Item 2.  Acquisition or Disposition of Assets.

     On November 18, 2002, in accordance with the Agreement and Plan of Merger
dated as of December 19, 2001, as amended (the "Merger Agreement"), among
Comcast Holdings Corporation (formerly named Comcast Corporation) ("Old
Comcast"), AT&T Corp. ("AT&T"), AT&T Broadband Corp. ("AT&T Broadband"),
Comcast Corporation (formerly named AT&T Comcast Corporation) ("New Comcast"),
AT&T Broadband Acquisition Corp., a wholly owned subsidiary of New Comcast
("AT&T Broadband Merger Sub"), and Comcast Acquisition Corp., a wholly owned
subsidiary of New Comcast ("Comcast Merger Sub"), among other things, (i) AT&T
contributed its broadband communications business to AT&T Broadband, (ii) AT&T
distributed one share of AT&T Broadband common stock as a dividend on each
outstanding share of AT&T common stock held as of 5:00 p.m., New York City
time, on November 15, 2002, (iii) Old Comcast merged with Comcast Merger Sub,
and (iv) AT&T Broadband merged with AT&T Broadband Merger Sub. As a result of
the mergers described in the preceding sentence, each of Old Comcast and AT&T
Broadband became a wholly owned subsidiary of New Comcast. As a result of the
Old Comcast merger, Old Comcast shareholders are entitled to receive for each
of their shares of Old Comcast common stock one share of a corresponding class
of New Comcast common stock. As a result of the AT&T Broadband merger, AT&T
Broadband shareholders are entitled to receive for each of their shares of AT&T
Broadband common stock .3235 of a share of New Comcast Class A common stock.

     On November 18, 2002, New Comcast issued a press release announcing the
completion of the transaction. A copy of the press release is attached as an
exhibit hereto and is incorporated by reference herein.

     The issuance of New Comcast common stock as described above was registered
under the Securities Act of 1933, as amended, pursuant to New Comcast's
registration statement on Form S-4 (File No. 333-82460) (the "Registration
Statement") filed with the Securities and Exchange Commission (the "SEC") and
declared effective on May 14, 2002. The joint proxy statement/prospectus of Old
Comcast and AT&T included in the Registration Statement contains additional
information about the transactions described above. The New Comcast Class A
common stock and the New Comcast Class A Special common stock have been
approved for listing on The Nasdaq Stock Market and will trade under the ticker
symbols "CMCSA" and "CMCSK", respectively. The descriptions of such classes of
New Comcast common stock contained under the caption "Description of AT&T
Comcast Capital Stock" in the joint proxy statement/prospectus referred to
above is incorporated by reference herein.

     Old Comcast Class A common stock and Old Comcast Class A Special common
stock were registered pursuant to Section 12(g) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and listed on The Nasdaq Stock
Market. In reliance on Rule 12g-3(d) of the Exchange Act, New Comcast Class A
common stock and New Comcast Class A Special common stock are deemed registered
under Section 12(g) of the Exchange Act. Old Comcast is delisting the Old
Comcast Class A common stock and Old Comcast Class A Special common stock from
The Nasdaq Stock Market and filing a Form 15 with the SEC to terminate the
registration under the Exchange Act of the Old Comcast Class A Common Stock and
the Old Comcast Class A Special Common Stock.

Item 5.  Other Events.

Approval of Federal Communications Commission

     On November 13, 2002, the Federal Communications Commission (the "FCC")
gave conditional approval to the transfer of certain FCC licenses required to
complete the transactions described above. The Memorandum Opinion and Order
issued by the FCC ordered AT&T and Old Comcast to place AT&T Broadband's
interest in Time Warner Entertainment, L.P. ("TWE") into irrevocable trust
prior to completion of the transaction and to fully divest the TWE interest
within five-and-a-half years after completion of the transaction. Until TWE is
divested, the order prohibits New Comcast from any involvement in the video
programming activities of TWE and also other cable systems in which TWE and New
Comcast both have interests. Copies of the trust agreements pursuant to which
AT&T Broadband's TWE interest will be placed into irrevocable trust are
attached as exhibits hereto and incorporated by reference herein.

Adoption of Stockholder Rights Plan

     On November 18, 2002, pursuant to the Merger Agreement, New Comcast
adopted a shareholder rights plan. To implement the plan, the New Comcast Board
declared a dividend of one preferred stock purchase right (a





"Right") on each share of each class of New Comcast common stock outstanding as
of 3:40 p.m., New York City time, on November 18, 2002. A description of the
shareholder rights plan is included in the registration statement on Form 8-A
filed by New Comcast on the date hereof to register the Rights under the
Exchange Act.

Repayment of Intracompany Debt

     In connection with the closing of the transaction described above in Item
2, AT&T Broadband repaid all intercompany debt owed by AT&T's broadband
business to AT&T's communications business. AT&T Broadband effected this
repayment by making a cash payment to AT&T in an amount equal to approximately
$5.85 billion and by issuing approximately $3.51 billion in debt to retire
existing AT&T debt. The cash payment referred to in the preceding sentence
reflected certain adjustments and was made with the proceeds of (i) a borrowing
by AT&T Broadband of $4 billion under a bridge loan facility dated April 26,
2002 among AT&T Broadband, New Comcast, the lenders party thereto and JPMorgan
Chase Bank, as Administrative Agent, and (ii) a borrowing by AT&T Broadband of
$2.5 billion under a credit agreement dated April 26, 2002 among AT&T
Broadband, New Comcast, the lenders party thereto and JPMorgan Chase Bank, as
Administrative Agent. The retirement of existing AT&T debt by AT&T Broadband
referred to above resulted from a recently completed debt exchange offer
pursuant to which AT&T Broadband issued debt guaranteed by New Comcast and
certain of its cable subsidiaries in an aggregate principal amount of
approximately $3.51 billion consisting of approximately $2.43 billion of 8.375%
Notes Due 2013 and approximately $1.08 billion of 9.455% Notes Due 2022.

Name Changes

     Promptly after completion of the transaction described above, Old Comcast
amended its articles of incorporation to change its name from "Comcast
Corporation" to "Comcast Holdings Corporation" and New Comcast amended its
articles of incorporation to change its name from "AT&T Comcast Corporation" to
"Comcast Corporation".

Restated Articles of Incorporation of New Comcast) and the Separation and

Subsidiary of Parent (and, in the event of a merger with a newly formed wholly
owned Subsidiary of Parent (which Subsidiary shall have performed no activities
other than those incident to its formation and the transactions contemplated
hereby), Comcast Shareholder will be the surviving entity in such merger)
immediately prior to the Effective Time in a transaction in which the members
of Comcast Shareholder (or such successor), in exchange for all of their
outstanding membership or other equity interests in Comcast Shareholder (or
such successor), would receive in the aggregate the same consideration that
Comcast Shareholder (or such successor) would have received pursuant to Section

acquire the shares of Parent Class B Common Stock pursuant to the merger
contemplated by this Section 4.01(e)) agrees to indemnify Parent in respect of
any liabilities (including tax liabilities) of Comcast Shareholder or arising
in connection with the transactions under this Section 4.01(e).

outstanding shares of Comcast Common Stock, AT&T Common Stock, AT&T Broadband
Common Stock or AT&T Broadband Class A Common Stock shall have been changed
into a different number of shares, by reason of any stock dividend (other than
to create the number of shares of AT&T Broadband Common Stock necessary to
effect the Distribution and, if the QUIPS Exchange occurs, the QUIPS Exchange
or otherwise as a result of the Separation and Distribution and other than to
create the number of shares of AT&T Broadband Class A Common Stock necessary to
effect the Subsidiary Preferred Stock Exchange (as defined in the Separation
and Distribution Agreement)), subdivision, split or combination of shares, the
consideration payable pursuant to Section 4.01 will, if appropriate, be
correspondingly adjusted to reflect such stock dividend, subdivision, split or
combination of shares. If the reverse stock split of AT&T Common Stock approved
at the AT&T Shareholders' Meeting occurs, appropriate adjustments will be made
in this Agreement and the other Transaction Agreements.

     (g) For purposes of Sections 4.01(a)-(d), 4.01(f) and 6.06(c) but not for
purposes of any other section of this Agreement (including, without limitation,
Sections 5.05 and 6.05), (i) any share of Comcast Common Stock held by any
Comcast Subsidiary will not be treated as a share of Comcast Common Stock held
in the treasury of Comcast and (ii) any share of AT&T Broadband Common Stock or
AT&T Broadband Class A Common Stock held by any AT&T Broadband Subsidiary will
not be treated as a share of AT&T Broadband Common Stock or AT&T Broadband
Class A Common Stock, as the case may be, held in the treasury of AT&T
Broadband.

     SECTION 4.02. Exchange of Certificates. (a) Exchange Agent. At or prior to
the Effective Time, Parent shall deposit with a bank or trust company jointly
designated by AT&T and Comcast (the "Exchange Agent"), for the benefit of the
holders of shares of AT&T Broadband Common Stock and Comcast Common Stock, for
exchange in accordance with this Article 4, through the Exchange Agent, the
shares of Parent Common Stock (such shares of Parent Common Stock, together
with any dividends or other distributions to the extent provided in Section
4.02(c), the "Exchange Fund") issuable pursuant to Section 4.01 in exchange for
outstanding shares of AT&T Broadband Common Stock and Comcast Common Stock;
provided that Parent shall not be required to deliver to the Exchange Agent the
portion, if any, of the Exchange Fund that is payable


                                      A-33



pursuant to Sections 4.03 and 4.04 unless and until the amounts payable
thereunder are determined.

     (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates that immediately prior to the Effective Time
represented outstanding shares of AT&T Broadband Common Stock or Comcast Common
Stock (the "Certificates"), other than shares to be canceled or retired or
converted into AT&T Broadband Surviving Corporation Common Stock or Comcast
Surviving Corporation common stock in each case in accordance with Section
4.01, (i) a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent, and shall be in such form
and have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock. Upon (i) surrender
of a Certificate for cancellation to the Exchange Agent, together with such
letter of transmittal, duly executed, or (ii) receipt of an "agents message"
(or such other evidence, if any, of transfer as the Exchange Agent may
reasonably request) in the case of a book-entry transfer of uncertificated
shares ("Uncertificated Shares"), and (in either case) receipt of such other
documents as may reasonably be required by the Exchange Agent, the holder of
such Certificate or Uncertificated Shares, as the case may be, shall be
entitled to receive in exchange therefor (A) such shares of Parent Common Stock
(which at Parent's option, shall be in uncertificated book-entry form unless a
physical certificate is requested or is otherwise required by applicable law)
representing in the aggregate that number of whole shares of Parent Common
Stock that such holder has the right to receive pursuant to the provisions of
this Article 4, (B) cash in lieu of any fractional shares of Parent Common
Stock to the extent provided in Section 4.02(e) and (C) any dividends or
distributions to the extent provided in Section 4.02(c), and any Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of
ownership of AT&T Broadband Common Stock or Comcast Common Stock that is not
registered in the transfer records of AT&T Broadband or Comcast, as the case
may be, the proper number of shares of Parent Common Stock, cash in lieu of any
fractional shares of Parent Common Stock pursuant to Section 4.02(e) and any
dividends or other distributions to which such holder is entitled pursuant to
Section 4.02(c) may be issued and delivered to a Person other than the Person
in whose name the Certificate so surrendered is registered if such Certificate
shall be properly endorsed or otherwise be in proper form for transfer and the
Person requesting such payment shall pay any transfer or other taxes required
by reason of the issuance of shares of Parent Common Stock to a Person other
than the registered holder of such Certificate or establish to the satisfaction
of Parent that such tax has been paid or is not applicable. Until surrendered
as contemplated by


                                      A-34



this Section 4.02, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
certificate representing the appropriate number of whole shares of Parent
Common Stock, cash in lieu of any fractional shares of Parent Common Stock to
the extent provided in Section 4.02(e) and any dividends and distributions to
the extent provided in Section 4.02(c). No interest will be paid or will accrue
on any cash payable in lieu of any fractional shares of Parent Common Stock.
Any amounts payable or deliverable pursuant to this Agreement shall be subject
to and made net of applicable withholding taxes to the extent such taxes are
imposed under applicable law as determined by Parent in its reasonable
discretion. To the extent that amounts are so withheld, those amounts shall be
treated for all purposes as having been paid to the holders of AT&T Broadband
Common Stock or Comcast Common Stock, as the case may be, in respect of which
the deduction and withholding was made. It is understood that the number of
whole shares of Parent Common Stock to be issued under the provisions of this
Article 4, other than Sections 4.03 and 4.04, will be issued and delivered to
the holders entitled thereto in advance of the issuance and delivery of shares
of Parent Common Stock to be issued under Sections 4.03 and 4.04, if any, and
that the shares of Parent Common Stock to be issued under Sections 4.03 and
4.04, if any, will be issued and delivered to the holders entitled thereto
promptly after the number of shares payable thereunder, if any, is determined.

     (c) Distributions with Respect to Unexchanged Shares. No dividends or
other distributions with respect to Parent Common Stock with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Parent Common Stock represented
thereby, and no cash payment in lieu of fractional shares shall be paid to any
such holder pursuant to Section 4.02(e) until the surrender of such Certificate
in accordance with this Article 4. Subject to the effect of applicable law and
to the other provisions hereof, following surrender of any such Certificate,
there shall be paid to the holder of the certificate representing whole shares
of Parent Common Stock issued in exchange therefor, without interest, (i) at
the time of such surrender, the amount of any cash payable in lieu of a
fractional share of Parent Common Stock to which such holder is entitled
pursuant to Section 4.02(e) and the amount of dividends or other distributions
with a record date after the Effective Time theretofore paid with respect to
such whole shares of Parent Common Stock and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to such surrender and a payment date subsequent to
such surrender payable with respect to such whole shares of Parent Common
Stock.

     (d) No Further Ownership Rights in AT&T Broadband Common Stock or Comcast
Common Stock. All shares of Parent Common Stock issued (and any


                                      A-35



cash paid pursuant to Section 4.02(c) or 4.02(e)) upon conversion of shares of
AT&T Broadband Common Stock or Comcast Common Stock in accordance with the
terms of this Article 4 shall be deemed to have been issued (and paid) in full
satisfaction of all rights pertaining to the relevant shares of AT&T Broadband
Common Stock or Comcast Common Stock, as the case may be, and there shall be no
further registration of transfers on the stock transfer books of the applicable
Surviving Corporation, of the shares of AT&T Broadband Common Stock or Comcast
Common Stock, as the case may be, that were outstanding immediately prior to
the Effective Time. If, after the Effective Time, Certificates are presented to
Parent or the Exchange Agent for any reason, they shall be canceled and
exchanged as provided in this Article 4, except as otherwise provided by
applicable law. Shares of Parent Common Stock shall not be issued to any Person
who is a Rule 145 Affiliate until Parent has received written undertakings from
such Person in the form attached as Exhibit B.

     (e) No Fractional Shares. (i) No certificates or scrip or shares of Parent
Common Stock representing fractional shares of Parent Common Stock or
book-entry credit of the same shall be issued upon the surrender for exchange
of Certificates or upon conversion of shares, and such fractional share
interests shall not entitle the owner thereof to vote or to any rights of a
shareholder of Parent.

          (ii) As promptly as practicable following the Fractional Shares
     Payment Date, the Exchange Agent shall determine the excess of (A) the
     aggregate number of shares of Parent Common Stock that would be
     distributed to holders of the Certificates and Uncertificated Shares
     pursuant to Section 4.02(b) if no effect were given to Section 4.02(e)(i)
     over (B) the aggregate number of whole shares of Parent Common Stock to be
     distributed to holders of the Certificates or Uncertificated Shares
     pursuant to Section 4.02(b) taking into account the effect of Section
     4.02(e)(i) (such excess, the "Excess Shares"). As soon as practicable
     after the Fractional Shares Payment Date, the Exchange Agent, as agent for
     the holders of the Certificates, shall sell the Excess Shares at
     then-prevailing prices on Nasdaq, all in the manner provided in Section
     4.02(e)(iii).

          (iii) The sale of the Excess Shares by the Exchange Agent shall be
     executed on Nasdaq, and shall be executed in round lots to the extent
     practicable. The proceeds from such sale or sales available for
     distribution to the holders of Certificates and Uncertificated Shares
     shall be reduced by the compensation payable to the Exchange Agent and the
     expenses incurred by the Exchange Agent, in each case, in connection with
     such sale or sales of the Excess Shares, including all related
     commissions, transfer taxes and other out-of-pocket transaction costs.
     Until the net proceeds of such sale or sales have been distributed to the
     holders of the Certificates


                                      A-36



     and Uncertificated Shares, the Exchange Agent shall hold such proceeds in
     trust for the holders of the Certificates and Uncertificated Shares (the
     "Common Stock Trust"). The Exchange Agent shall determine the portion of
     the Common Stock Trust to which each holder of a Certificate or
     Uncertificated Share shall be entitled, if any, by multiplying the amount
     of the aggregate net proceeds comprising the portion of the Common Stock
     Trust attributable to the relevant class of Parent Common Stock by a
     fraction, the numerator of which is the amount of the fractional share
     interest in such class of Parent Common Stock to which such holder of a
     Certificate or Uncertificated Share is entitled and the denominator of
     which is the aggregate amount of fractional share interests in such class
     to which all holders of the Certificates and Uncertificated Shares are
     entitled.

          (iv) As soon as practicable after the determination of the amount of
     cash, if any, to be paid to holders of Certificates and Uncertificated
     Shares in lieu of any fractional share interests, the Exchange Agent shall
     make available such amounts, without interest, to such holders of
     Certificates and Uncertificated Shares that have surrendered their
     Certificates in accordance with this Article 4.

     (f) Termination of Exchange Fund and Common Stock Trust. Any portion of
the Exchange Fund and Common Stock Trust that remains undistributed for one
year after the Effective Time shall be delivered to Parent, upon demand, and
any holders of Certificates and Uncertificated Shares who have not theretofore
complied with this Article 4 shall thereafter look only to Parent for payment
of their claim for Parent Common Stock, any cash in lieu of fractional shares
of Parent Common Stock, and any dividends or other distributions with respect
to Parent Common Stock.

     (g) AT&T Stock Options and Other AT&T Equity-Based Awards. (i) At the
Effective Time, all options to purchase, and stock appreciation rights with
respect to, shares of AT&T Broadband Common Stock ("AT&T Stock Options" and
"AT&T SARs", respectively) that are outstanding and unexercised as of the
Effective Time shall cease to represent rights with respect to shares of AT&T
Broadband Common Stock and shall be converted automatically into options to
purchase, or stock appreciation rights with respect to, shares of Parent
Indexed Stock ("AT&T Converted Stock Options" and "AT&T Converted SARs",
respectively) and Parent shall assume each such AT&T Converted Stock Option and
AT&T Converted SAR, on the same terms and conditions as applied to such AT&T
Stock Option or AT&T SAR immediately before the Effective Time (including
without limitation any vesting as a result of the consummation of the
transactions contemplated hereby); provided, however, that, from and after the
Effective Time, (A) the number of shares of Parent Indexed Stock subject to
such


                                      A-37



AT&T Converted Stock Option or AT&T Converted SAR, as applicable, shall be
equal to the number of shares, rounded to the nearest whole share, of Parent
Indexed Stock whose fair market value, immediately after the Effective Time, is
equal to (a) minus (b), where "(a)" is the aggregate fair market value,
determined immediately prior to the Distribution using the AT&T Closing Stock
Value, of the AT&T Common Stock subject to the original option or stock
appreciation right (the "Original Award") with respect to which such AT&T Stock
Option or AT&T SAR was issued pursuant to the Employee Benefits Agreement; and
"(b)," in the case of a Broadband Employee, is zero, and in the case of a
Former Employee is the aggregate fair market value, determined immediately
after the Distribution using the AT&T Opening Stock Value (as such term is
defined in the Employee Benefits Agreement), of the AT&T Common Stock subject
to the "adjusted AT&T Option" into which the Original Award was partially
converted pursuant to Section 5.3(b) of the Employee Benefits Agreement; and
(B) the per share exercise price under such AT&T Converted Stock Option or AT&T
Converted SAR, as applicable, as of the Effective Time, shall be adjusted by
dividing the aggregate exercise price of the Original Award relating to such
AT&T Stock Option or AT&T SAR, as applicable (less, in the case of a Former
Employee, the aggregate exercise price of the relevant "adjusted AT&T Option"
referred to in (A) above), by the number of shares of Parent Indexed Stock to
which such AT&T Converted Stock Option or AT&T Converted SAR is subject,
rounded to the nearest one-hundredth of a cent. Notwithstanding the foregoing,
the number of shares and the per share exercise price of each AT&T Converted
Stock Option that is, as of the Effective Time, after giving effect to any
vesting as a result of the transactions contemplated hereby, an "incentive
stock option" (as defined in Section 422 of the Code) and each related AT&T
Converted SAR, if any, shall be adjusted in accordance with the requirements of
Section 424 of the Code. Accordingly, with respect to any incentive stock
options, fractional shares shall be rounded down to the nearest whole number of
shares, and, where necessary, the per share exercise price shall be rounded up
to the nearest cent. For purposes of this Section 4.02, the fair market value
of a share of Parent Indexed Stock shall be determined using the opening
per-share price of Parent Indexed Stock as listed on Nasdaq as of the opening
of trading on the First Trading Day following the Effective Time; provided,
however, that if the Effective Time occurs at a time when Nasdaq is open for
trading, fair market value shall be determined using the price at which Parent
Indexed Stock trades as of the moment immediately after the Effective Time;
provided, further, that if the Effective Time occurs prior to the opening of
trading on Nasdaq, the fair market value shall be determined using the price at
which the Parent Indexed Stock First trades after the opening of trading on
this day.

          (ii) At the Effective Time, all shares of AT&T Broadband restricted
     stock outstanding as of the Effective Time shall be converted


                                      A-38



     automatically into the right to receive Parent Common Stock on the terms
     and conditions set forth in the applicable sections of this Article 4 and
     all other equity based awards based upon shares of AT&T Broadband Common
     Stock (collectively, the "AT&T Equity Awards") outstanding as of the
     Effective Time shall be converted automatically into equivalent awards
     based upon shares of Parent Indexed Stock (collectively, the "AT&T
     Converted Equity Awards"), on the same terms and conditions as applied to
     such AT&T Equity Award immediately before the Effective Time (including
     without limitation any vesting as a result of the consummation of the
     transactions contemplated hereby); provided, however, that from and after
     the Effective Time, the number of shares of Parent Indexed Stock subject
     to such AT&T Converted Equity Award shall be equal to the number of shares
     of Parent Indexed Stock whose fair market value, immediately after the
     Effective Time, is equal to the aggregate fair market value, determined
     immediately prior to the Distribution using the AT&T Closing Stock Value,
     of the AT&T Common Stock subject to the original equity based award with
     respect to which such AT&T Equity Award was issued pursuant to the
     Employee Benefits Agreement.

          (iii) At or prior to the Effective Time, Parent shall reserve for
     issuance the number of shares of Parent Indexed Stock necessary to satisfy
     Parent's obligations under this Section 4.02(g). No later than five
     Business Days after the Effective Time, Parent shall File with the SEC a
     registration statement on Form S-8 (or other appropriate form) (an "S-8")
     under the 1933 Act with respect to the shares of Parent Indexed Stock
     subject to AT&T Converted Stock Options, AT&T Converted SARs and AT&T
     Converted Equity Awards issued pursuant to this Section 4.02(g), and shall
     use all reasonable best efforts to maintain the effectiveness of the
     applicable S-8 and current status of the prospectus related to the
     applicable S-8, as well as comply with any applicable state securities or
     "blue sky" laws, for so long as any such AT&T Converted Stock Options,
     AT&T Converted SARs and/or AT&T Converted Equity Awards remain
     outstanding.

     (h) Comcast Stock Options and other Comcast Equity-Based Awards. (i) At
the Effective Time, all options to purchase shares of Comcast Class A Special
Common Stock ("Comcast Stock Options") granted by Comcast or any Comcast
Subsidiary pursuant to the terms of any stock option or incentive plan and
held, as of the Effective Time, by an employee of Comcast of any Comcast
Subsidiary (or any beneficiary thereof) shall cease to represent rights to
purchase shares of Comcast Class A Special Common Stock and shall be converted
automatically into options to purchase ("Comcast Converted Stock Options"),


                                      A-39



on the same terms and conditions as applied to such Comcast Stock Option
immediately prior to the Effective Time, that number of shares of Parent
Indexed Stock, rounded to the nearest whole share, whose fair market value,
immediately after the Effective Time, is equal to the aggregate fair market
value, determined immediately prior to the Effective Time, of the Comcast Class
A Special Common Stock subject to such Comcast Stock Option, at a per share
exercise price equal to the aggregate exercise price of such Comcast Stock
Option divided by the number of shares of Parent Indexed Common Stock to which
such Comcast Converted Stock Option is subject. Notwithstanding the foregoing,
the number of shares and the per share exercise price of each Comcast Converted
Stock Option that is, as of the Effective Time, an "incentive stock option" (as
defined in Section 422 of the Code) and each related Comcast Converted SAR, if
any, shall be adjusted in accordance with the requirements of Section 424 of
the Code. Accordingly, with respect to any incentive stock options, fractional
shares shall be rounded down to the nearest whole number of shares, and, where
necessary, the per share exercise price shall be rounded up to the nearest
cent.

          (ii) At the Effective Time, Comcast restricted stock awards
     (collectively, the "Comcast Restricted Stock Awards") shall be converted
     automatically into (A) if the Preferred Structure Approval has been
     obtained, equivalent awards based upon shares of Parent Class A Common
     Stock or (B) if the Preferred Structure Approval has not been obtained,
     equivalent awards based upon shares of Parent Class C Common Stock
     (collectively, the "Comcast Converted Restricted Stock Awards"), on the
     same terms and conditions as applied to such Comcast Restricted Stock
     Award immediately prior to the Effective Time. The number of shares of
     Parent Class A Common Stock or Parent Class C Common Stock, as the case
     may be, subject to such Comcast Converted Restricted Stock Award shall be
     that number of shares of Parent Class A Common Stock or Parent Class C
     Common Stock, as the case may be, rounded to the nearest share, whose fair
     market value, immediately after the Effective Time is equal to the
     aggregate fair market value, determined immediately prior to the Effective
     Time, of the shares of Comcast Common Stock that were subject to such
     Comcast Restricted Stock Awards. All other equity based awards based upon
     shares of Comcast Class A Special Common Stock (collectively, the "Comcast
     Equity Awards") outstanding as of the Effective Time shall be converted
     automatically into equivalent awards based upon shares of Parent Indexed
     Stock (collectively, the "Comcast Converted Equity Awards"), on the same
     terms and conditions as applied to such Comcast Equity Award immediately
     prior to the Effective Time. The number of shares of Parent Indexed Stock
     subject to such Comcast Converted Equity Award shall be the number of
     shares of Parent Indexed Stock, rounded to the nearest


                                      A-40



     share, whose fair market value, immediately after the Effective Time, is
     equal to the aggregate fair market value, determined immediately prior to
     the Effective Time, of the shares of Comcast Common Stock that were
     subject to such Comcast Equity Award.

          (iii) At or prior to the Effective Time, Parent shall reserve for
     issuance the number of shares of Parent Indexed Stock necessary to satisfy
     Parent's obligations under this Section 4.02(h). No later than five
     Business days after the Effective Time, Parent shall File with the SEC an
     S-8 under the 1933 Act with respect to the shares of Parent Indexed Stock
     subject to the Comcast Converted Stock Options and Comcast Converted
     Equity Awards issued pursuant to this Section 4.02(h), and shall use
     reasonable best efforts to maintain the effectiveness of the applicable
     S-8 and current status of the prospectus related to the applicable S-8, as
     well as comply with any applicable state securities or "blue sky" laws,
     for so long as any such Comcast Converted Stock Options and/or Comcast
     Converted Equity Awards remain outstanding.

     (i) No Liability. None of the parties hereto or the Exchange Agent shall
be liable to any Person in respect of any shares of Parent Common Stock (or
dividends or distributions with respect thereto) or cash from the Exchange Fund
or the Common Stock Trust delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. Any shares of Parent
Common Stock, any cash in lieu of fractional shares of Parent Common Stock or
any dividends or other distributions with respect to Parent Common Stock
payable hereunder would otherwise escheat to or become the property of any
Governmental Authority, such shares, cash, dividends or other distributions
shall, to the extent permitted by applicable law, become the property of
Parent, free and clear of all claims or interest of any Person previously
entitled thereto.

     (j) Investment of Exchange Fund and Common Stock Trust. The Exchange Agent
shall invest any cash included in the Exchange Fund and Common Stock Trust, as
directed by Parent, on a daily basis; provided that no such investment or loss
thereon shall affect the amounts payable or the timing of the amounts payable
to AT&T Broadband or Comcast shareholders pursuant to this Article 4. Any
interest and other income resulting from such investments shall be paid to
Parent.

     (k) Lost Certificates. If any Certificate is lost, stolen or destroyed,
upon the making of an affidavit of that fact by the Person claiming such
Certificate to be lost, stolen or destroyed and executing an indemnity
reasonably satisfactory to Parent (and, if required by Parent in the case of a
Certificate representing more than 1,000 shares, the posting by such Person of
a bond, in such reasonable


                                      A-41



amount as Parent may direct, as indemnity) against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue, in
exchange for such lost, stolen or destroyed Certificate and in respect of the
shares of AT&T Broadband Common Stock or Comcast Common Stock, as the case may
be, formerly represented by such lost Certificate, that number of whole shares
of Parent Common Stock that such holder has the right to receive pursuant to
the provisions of this Article 4, cash in lieu of any fractional shares of
Parent Common Stock to the extent provided in Section 4.02(e) and any dividends
or distributions to the extent provided in Section 4.02(c).

     (l) If (i) any holder of AT&T Common Stock does not receive shares of AT&T
Broadband Common Stock in the Distribution in respect of such holder's shares
of AT&T Common Stock because such holder has purported to exercise rights
pursuant to Section 910 of the NYBCL in respect of such holder's shares of AT&T
Common Stock and (ii) such rights are subsequently invalidated or such holder
subsequently withdraws his purported exercise of such rights, then Parent shall
deliver to such holder at such time (or at such later time as is otherwise
provided for such delivery) the merger consideration payable pursuant to this
Article 4 in respect of the shares of AT&T Broadband Common Stock issuable in
the Distribution in respect such holder's shares of AT&T Common Stock.

     (m) Promptly after the Effective Time, AT&T Broadband shall cause its
Subsidiaries to exchange the shares of AT&T Broadband Class A Common Stock for
the shares of Parent Common Stock into which they were converted pursuant to
Section 4.01 on terms that are (to the extent applicable) substantially
consistent with the exchange arrangements set forth in this Section 4.02,
including, without limitation, Sections 4.02(c) and 4.02(e), with respect to
the shares of AT&T Broadband Common Stock converted pursuant to Section 4.01.

     SECTION 4.03. Section 355(e) Top-up. (a) In the event that the Preferred
Structure Approval has been obtained and if, but for a disparity in the per
share value of the Parent Class A Common Stock and the Parent Class A Special
Common Stock, the Qualified Holders would have received a number of shares of
Parent Common Stock pursuant to Section 4.01(a)(iii) at the Effective Time that
represents more than 50% of the total value of all shares of Parent Common
Stock (excluding any shares of Parent Common Stock held by Subsidiaries of
Parent), Parent shall issue additional shares of Parent Common Stock to the
holders of record (as of immediately prior to the Effective Time) of AT&T
Broadband Common Stock in an amount sufficient to ensure that Qualified Holders
will be treated as holding at the Effective Time more than 50% of the value of
all shares of Parent Common Stock (excluding any shares of Parent Common Stock
held by Subsidiaries of Parent); provided, however, that Parent shall not be
obligated to issue additional shares pursuant to this Section 4.03(a) to the
extent that AT&T


                                      A-42



has issued shares in breach of Section 8.01(d)(v) of this Agreement. The
holders of record of AT&T Broadband Class A Common Stock as of the Effective
Time shall receive on a per share basis the same amount of additional shares of
Parent Common Stock as the holders of AT&T Broadband Common Stock receive
pursuant to the preceding sentence.

     (b) In the event that the Preferred Structure Approval has not been
obtained and if, but for a disparity in the per share value of the Parent Class
C Common Stock and the Parent Class A Special Common Stock, the Qualified
Holders would have received a number of shares of Parent Common Stock pursuant
to Section 4.01(c)(iii) at the Effective Time that represents more than 50% of
the total value of all shares of Parent Common Stock (excluding any shares of
Parent Common Stock held by Subsidiaries of Parent), Parent shall issue
additional shares of Parent Common Stock to the holders of record of AT&T
Broadband Common Stock (as of immediately prior to the Effective Time) in an
amount sufficient to ensure that Qualified Holders will be treated as holding
at the Effective Time more than 50% of the value of all shares of Parent Common
Stock (excluding any shares of Parent Common Stock held by Subsidiaries of
Parent); provided, however, that Parent shall not be obligated to issue
additional shares pursuant to this Section 4.03(b) to the extent that AT&T has
issued shares in breach of Section 8.01(d)(v) of this Agreement. The holders of
record of AT&T Broadband Class A Common Stock as of the Effective Time shall
receive on a per share basis the same amount of additional shares of Parent
Common Stock as the holders of AT&T Broadband Common Stock receive pursuant to
the preceding sentence.

     (c) For purposes of this Section 4.03, (i) "Qualified Holders" shall mean
the holders of AT&T Broadband Common Stock other than holders that receive such
shares "pursuant to a plan or series of related transactions" with the
Distribution (within the meaning of Section 355(e) of the Code), (ii) the value
of the shares of each class of Parent Common Stock shall be determined as of
the Closing Date unless AT&T receives a ruling from the Internal Revenue
Service that permits Comcast and AT&T to use the valuation methodology used in
Section 4.04 (in which event such methodology will be used) and (iii) the value
of the shares of Parent Class B Common Stock shall be determined in accordance
with Section 4.03 of the Comcast Disclosure Schedule.

     SECTION 4.04. Additional Payments. (a) In the event that the Preferred
Structure Approval has been obtained and prior to the Effective Time Standard &
Poor's has not committed that the Parent Class A Common Stock will be included
in the Index immediately after the Effective Time, then in addition to the

wholly-owned Subsidiaries shall receive, in lieu of the number of shares
representing such excess voting power, an equivalent number of shares of Parent
Class A Special Common Stock.

circumstances exists that may reasonably give rise to a claim or lawsuit,
against any of the Comcast Benefit Arrangements, the Comcast Employee Plans and
the Comcast International Plans, any fiduciaries thereof with respect to their
duties thereto or the assets of any of the trusts thereunder, that could
reasonably be expected to result in any material liability of Comcast or any of

                                      A-56

exceptions as, individually or in the aggregate, have not had, and would not
reasonably be expected to have, a Comcast Material Adverse Effect, (i) each of
the contracts, agreements and commitments of Comcast and the Comcast
Subsidiaries is valid and in full force and effect and (ii) neither Comcast nor
any of the Comcast Subsidiaries has violated any provision of, or committed or
failed to perform any act that, with or without notice, lapse of time, or both,
would constitute a default under the provisions of any such contract, agreement
or commitment. To the knowledge of Comcast, no counterparty to any such
contract, agreement or commitment has violated any provision of, or committed
or failed to perform any act that, with or without notice, lapse of time, or
both would constitute a default or other breach under the provisions of, such
contract, agreement or commitment, except for defaults or breaches that,

any joint venture or partnership agreement pursuant to which it is obligated to
make capital contributions in excess of (x) $25,000,000 during the current or
any succeeding calendar year or (y) $100,000,000 during the remaining term of

     SECTION 5.22. Vote Required. The only votes of the holders of any class or
series of capital stock of Comcast that are or may be necessary to approve and
adopt this Agreement and the transactions contemplated hereby and the Parent
Charter that will be implemented at the Effective Time, including its corporate
governance provisions, are (i) the affirmative vote of the holders of shares of

required to approve such proposals, except that the Preferred Structure
Approval is required in order to effect the provisions hereof that are
expressly subject to obtaining the Preferred Structure Approval.

necessary to exempt the Comcast Merger and this Agreement and the transactions
contemplated hereby from the restrictions of Section 2555 of the PBCL or
otherwise to make such provisions inapplicable to this Agreement and the

                     REPRESENTATIONS AND WARRANTIES OF AT&T

binding agreement of AT&T and each AT&T Subsidiary that is a party thereto,
enforceable against AT&T and each such AT&T Subsidiary in accordance with its
terms, except (i) as the same may be limited by applicable bankruptcy,
insolvency, moratorium or similar laws of general application relating to or
affecting creditors' rights and (ii) for the limitations imposed by general
principles of equity.

extent related to the AT&T Broadband Group, AT&T Broadband or an AT&T Broadband

States federal income Tax Returns of AT&T and the AT&T Subsidiaries have been
examined and settled with the IRS (or the applicable statutes of limitation for

expired) for all years through 1992; (f) no extension of the statute of
limitations on the assessment of any Taxes has been granted by AT&T or any AT&T
Subsidiary and is currently in effect; (g) except for complete and accurate
copies of Tax sharing agreements and amendments thereto made available to
Comcast prior to the execution of this Agreement and listed in Section 6.16 of
the AT&T Disclosure Schedule, no agreements relating to the allocation or
sharing of Taxes exist between AT&T and/or any of the AT&T Subsidiaries, on the
one hand, and a third party, on the other hand; and (h) there are no Liens for
Taxes on any of the assets of AT&T or any AT&T Subsidiary except Liens for
current Taxes not yet due and payable.

     SECTION 6.17. Tax Opinions. Neither AT&T nor any AT&T Subsidiary has taken
any action or knows of any facts or circumstances relating to AT&T or any AT&T
Subsidiary that would prevent (i) the ruling or opinion referred to in Section

delivering the opinion referred to in Section 10.02(b) as of the date hereof.

     SECTION 6.18. Employee Benefit Plans and Labor Matters. Except as have not
had and would not reasonably be expected to have, individually or in the
aggregate, an AT&T Broadband Material Adverse Effect:

     (a) Section 6.18(a) of the AT&T Disclosure Schedule contains a true and
complete list, as of the date hereof, of all Broadband Employee Plans and all
Broadband Benefit Arrangements. Copies of each Broadband Employee Plan and
Broadband Benefit Arrangement (and, if applicable, related trust agreements)
and all amendments thereto have been made available to Comcast as of the date
hereof, together with the three most recent annual reports (Form 5500
including, if applicable, Schedule B thereto) and the most recent actuarial
valuation report prepared in connection with any Broadband Employee Plan.

     (b) No "accumulated funding deficiency" (as defined in Section 412 of the
Code) has been incurred with respect to any Broadband Employee Plan subject to
such Section 412 of the Code, whether or not waived. No "reportable event"
(within the meaning of Section 4043 of ERISA) for which the 30-day notice
period has not been waived, and no event described in Section 4062 or 4063 of
ERISA, has occurred in connection with any Broadband Employee Plan. Neither
AT&T nor any ERISA Affiliate of AT&T has (i) engaged in, or is a successor or
parent corporation to an entity that has engaged in, a transaction described in
Sections 4069 or 4212(c) of ERISA or (ii) incurred, or reasonably expects to
incur prior to the Effective Time, (A) any liability under Title IV of ERISA
arising in


                                      A-69



connection with the termination of, or a complete or partial withdrawal from,
any plan covered or previously covered by Title IV of ERISA or (B) any
liability under Section 4971 of the Code that in either case could become a
liability of Parent, AT&T Broadband, any AT&T Broadband Subsidiary, Comcast,
any Comcast Subsidiary, or any of their respective ERISA Affiliates after the
Effective Time. No Broadband Employee Plan is a Multiemployer Plan.

     (c) As of June 30, 2001, the fair market value of the assets of each
Broadband Pension Plan (excluding for these purposes any accrued but unpaid
contributions) exceeded the present value of the pension benefit obligations
accrued under such Broadband Pension Plan calculated pursuant to SFAS No. 87,
"Employers' Accounting for Pensions". As of September 30, 2001, the aggregate
unfunded liability of AT&T and any AT&T Subsidiary in respect of all Broadband
Deferred Compensation Plans, computed using reasonable actuarial assumptions
and determined as if all benefits under such plans were vested and payable as
of such date, did not exceed $132 million.

     (d) Neither AT&T, AT&T Broadband nor any AT&T Broadband Subsidiary has any
liability with respect of post-retirement health, medical or life insurance
benefits for retired, former or current Broadband Employees except as to
required to avoid excise tax under Section 4980B of the Code.

     (e) Each Broadband Employee Plan that is intended to be qualified under
Section 401(a) of the Code is so qualified and a favorable determination letter
is currently in effect for each such Broadband Employee Plan. To the knowledge
of AT&T, no fact or circumstance exists giving rise to a material likelihood
that such Broadband Employee Plan would not be treated as qualified by the
Internal Revenue Service.

     (f) There is no contract, plan or arrangement (written or otherwise)
covering any Broadband Employee that, individually or in the aggregate, could
give rise to the payment of any amount by AT&T Broadband or any of the AT&T
Broadband Subsidiaries that would not be deductible pursuant to the terms of
Sections 162(m) or 280G of the Code.

     (g) AT&T has made available to Comcast, as of the date hereof, a true and
complete list and copies of each material Broadband International Plan, other
than plans mandated by applicable law.

     (h) Each Broadband Employee Plan, Broadband Benefit Arrangement and
Broadband International Plan has been maintained in compliance with its terms
and with the requirements prescribed by all applicable laws, statutes, orders,
rules and regulations (including any special provisions relating to
registration or


                                      A-70



qualification where such plan was intended to be so registered or qualified)
and has been maintained in good standing with applicable Governmental
Authorities.

     (i) There has been no amendment to, written interpretation or announcement
(whether or not written) by AT&T or any of its Affiliates relating to, or
change in employee participation coverage under, a Broadband Employee Plan,
Broadband Benefit Arrangement or Broadband International Plan which would
increase materially the expense of maintaining such plan above the level of
expense incurred in respect thereof for the Fiscal year ended December 31,
2000.

     (j) No Broadband Employee, former Broadband Employee or independent
contractor of AT&T Broadband or any of the AT&T Broadband Subsidiaries, will
become entitled to any bonus, retirement, severance, job security or similar
benefit or enhanced such benefit (including acceleration of vesting or exercise
of an incentive award) as a result of the transactions contemplated hereby
(either alone or together with any other event).

     (k) Section 6.18(k) of the AT&T Disclosure Schedule sets forth a list of
all collective bargaining agreements to which AT&T Broadband or any of the AT&T
Broadband Subsidiaries is a party or otherwise covering any employee of AT&T
Broadband or any of the AT&T Broadband Subsidiaries. None of AT&T, AT&T
Broadband nor any of the AT&T Broadband Subsidiaries is involved in, or to the
knowledge of AT&T, threatened with any labor dispute, work stoppage, labor
strike, slowdown or grievance relating to the AT&T Broadband Group. To the
knowledge of AT&T, there is no organizing effort or representation question at
issue with respect to any collective bargaining unit of AT&T Broadband or any
of the AT&T Broadband Subsidiaries or any employee of AT&T Broadband or any of
the AT&T Broadband Subsidiaries.

     (l) There are no pending or threatened claims (other than claims for
benefits in the ordinary course), lawsuits or arbitrations that have been
asserted or instituted, and, to the knowledge of AT&T, no set of circumstances
exists that may reasonably give rise to a claim or lawsuit, against any of the
Broadband Benefit Arrangements, the Broadband Employee Plans and the Broadband
International Plans, any Fiduciaries thereof with respect to their duties
thereto or the assets of any of the trusts thereunder, that could reasonably be
expected to result in any material liability of AT&T or any of the AT&T
Subsidiaries to the PBGC, the United States Department of Treasury, the United
States Department of Labor, any foreign governmental authority, any
Multiemployer Plan, any of the Broadband Benefit Arrangements, the Broadband
Employee Plans and the Broadband International Plans, any participant therein,
or any other Person.

     SECTION 6.19. Environmental Matters. (a) Except as have not had and would
not reasonably be expected to have, individually or in the aggregate, an AT&T
Broadband Material Adverse Effect:

          (i) no notice, notification, demand, request for information,
     citation, summons or order has been received, no complaint has been Filed,
     no penalty has been assessed, and no investigation, action, claim, suit,
     proceeding or review is pending or, to the knowledge of AT&T, threatened
     by any Governmental Authority or other Person with respect to AT&T (to the
     extent relating to the AT&T Broadband Group), AT&T Broadband, any AT&T
     Broadband Subsidiary or the AT&T Broadband Group relating to or arising
     out of any Environmental Law;

          (ii) each member of AT&T (to the extent relating to the AT&T
     Broadband Group), AT&T Broadband, the AT&T Broadband Subsidiaries and the
     AT&T Broadband Group is and has been in compliance with all Environmental
     Laws and all Environmental Permits; and

          (iii) there are no liabilities of AT&T (to the extent relating to the
     AT&T Broadband Group), AT&T Broadband, the AT&T Broadband Subsidiaries or
     the AT&T Broadband Group of any kind whatsoever, whether accrued,
     contingent, absolute, determined, determinable or otherwise arising under
     or relating to any Environmental Law, and there are no facts, conditions,
     situations or set of circumstances that would reasonably be expected to
     result in, or be the basis for, any such liability.

     (b) There have been no environmental investigations, studies, audits,
tests, reviews or other analyses conducted of which AT&T has knowledge in
relation to the current or prior business of the AT&T Broadband Group, AT&T (to
the extent relating to the AT&T Broadband Group), AT&T Broadband or any AT&T
Broadband Subsidiary or any property or facility now or previously owned or
leased by the AT&T Broadband Group, AT&T (to the extent relating to the AT&T
Broadband Group), AT&T Broadband or any AT&T Broadband Subsidiary that reveal
matters that, individually or in the aggregate, have had, or would reasonably
be expected to have, an AT&T Broadband Material Adverse Effect.

     (c) For purposes of this Section 6.19, the terms "AT&T Broadband Group",
"AT&T (to the extent relating to the AT&T Broadband Group)", "AT&T Broadband"
and "AT&T Broadband Subsidiary" shall include any entity that is, in whole or
in part, a predecessor of the AT&T Broadband Group, AT&T (to the extent

Subsidiary.


                                      A-72



     SECTION 6.20. Intellectual Property. The Transaction Agreements, taken as
a whole, including the Separation and Distribution Agreement and the assets
transferred thereby, the Intellectual Property Agreement (as defined in the
Separation and Distribution Agreement) and the intellectual property licenses
granted thereby and the other Ancillary Agreements and all services furnished
thereby provide sufficient rights in or access to intellectual property owned
by AT&T to enable the AT&T Broadband Group, without violating such AT&T
intellectual property, to conduct its business immediately after the Effective
Time in all material respects as that business was conducted by the AT&T
Broadband Group immediately prior to the Effective Time. Neither AT&T nor any
AT&T Subsidiary has received any notice of infringement of or conflict with,
and, to AT&T's knowledge, there are no infringements of or conflicts with, the
rights of any Person with respect to the use of any trademark, service mark,
trade name, invention, patent, trade secret, copyright, know-how (including any
registrations or applications for registration of any of the foregoing) or any
other similar type of proprietary intellectual property right that, in either
such case, individually or in the aggregate, have had or would reasonably be
expected to have, an AT&T Broadband Material Adverse Effect.

     SECTION 6.21. Contracts. Except as set forth in Section 6.21 of the AT&T
Disclosure Schedule and except as may relate to TWE or At Home, neither AT&T
(to the extent relating to the AT&T Broadband Group), AT&T Broadband nor any of
the AT&T Broadband Subsidiaries is a party to or bound by (a) any "material
contract" (as defined in Item 601(b)(10) of Regulation S-K of the SEC) or any
agreement, contract or commitment that would be such a "material contract" but
for the exception for contracts entered into in the ordinary course of
business, (b) any non-competition agreement or any other agreement or
obligation that materially limits or will materially limit AT&T Broadband, the
AT&T Broadband Group or the AT&T Broadband Subsidiaries (or, after the Mergers,
Parent, Comcast or any of the Comcast Subsidiaries) from engaging in the
business of providing telephony, data transmission services, cable television
or programming content, or (c) any agreement, contract or commitment to which
Liberty Media Corporation, AT&T Wireless or any of their respective
Subsidiaries is a party that is material to or not in the ordinary course of

an AT&T Broadband Material Adverse Effect and except as may relate to TWE or At
Home, (i) each of the contracts, agreements and commitments of the AT&T
Broadband Group, AT&T (to the extent relating to the AT&T Broadband Group),
AT&T Broadband and the AT&T Broadband Subsidiaries is valid and in full force
and effect and (ii) neither the AT&T Broadband Group, AT&T (to the extent
relating to the AT&T Broadband Group), AT&T Broadband nor any of the AT&T


                                      A-73

agreement or commitment has violated any provision of, or committed or failed
to perform any act that, with or without notice, lapse of time, or both would
constitute a default or other breach under the provisions of such contract,
agreement or commitment, except for defaults or breaches that, individually or
in the aggregate, have not had, or would not reasonably be expected to have, an
AT&T Broadband Material Adverse Effect. Except as set forth in Section 6.21 of
the AT&T Disclosure Schedule and except as may relate to TWE or At Home,
neither AT&T (to the extent relating to the AT&T Broadband Group), the AT&T
Broadband Group, AT&T Broadband nor any AT&T Broadband Subsidiary is a party
to, or otherwise a guarantor of or liable with respect to (including pursuant
to any keepwell agreement), (i) any material interest rate, currency or other
swap or derivative transaction (other than those entered into in the ordinary
course of business solely for hedging purposes) or (ii) any Indebtedness of any
other Person except a wholly owned AT&T Broadband Subsidiary. Except as set

which it is obligated to make capital contributions in excess of (x)
$25,000,000 during the current or any succeeding calendar year or (y)
$100,000,000 during the remaining term of such agreement. Subject to applicable
confidentiality restrictions, AT&T has provided or made available to Comcast

favor of approval of the Parent Charter to be implemented at the Effective
Time, including its corporate governance provisions (the "AT&T Parent Charter

Shareholders' Approvals"), which the parties acknowledge are conditions to the
obligations of the parties to effect the Separation, Distribution and Mergers,
no other vote of the holders of any class or series of capital stock of AT&T
will be necessary to approve and adopt this Agreement and the transactions
contemplated


                                      A-74

necessary to exempt the AT&T Broadband Merger and this Agreement and the
transactions contemplated hereby from the restrictions of Section 203 of the
DGCL or otherwise to make such provisions inapplicable to this Agreement and
the transactions contemplated hereby, and, accordingly, neither Section 203 of
the DGCL nor any other antitakeover or similar statute or regulation applies or
purports to apply to any such transactions. No other "control share

Partnership Agreement or any related agreement or that materially affects the
rights or obligations of AT&T (to the extent relating to the AT&T Broadband
Group), AT&T Broadband, the AT&T Broadband Group or the AT&T Broadband
Subsidiaries with respect to TWE or any TWE Subsidiary or that was entered into
in connection with or relates to AT&T's TWE interest (the "TWE Contracts").
None of AT&T (to the extent relating to the AT&T Broadband Group), AT&T
Broadband or any of the AT&T Broadband Subsidiaries has violated any material
provision of, or committed or failed to perform any act that, with or without

AT&T Broadband Material Adverse Effect. The AT&T Broadband Group owns a Class A

                                      A-75



pursuant to Article VIII of the TWE Partnership Agreement (capitalized terms
used in this sentence and not defined have the meanings set forth in the TWE

     (A) through (F) above to the extent that AT&T Broadband and the AT&T
     Broadband Subsidiaries are not bound thereby and the AT&T Broadband Group

     in any way restrict AT&T or any of its Subsidiaries from taking any action
     (including granting any stay bonuses and paying or providing other
     compensation pursuant to retention plans or similar arrangements) on
     reasonable commercial terms that AT&T


                                      A-88



     determines is reasonably necessary or desirable in order to retain or

     Transaction Agreements inaccurate in any material respect at the Effective
     Time;

          (xxiv) take any action that would, or would reasonably be expected
     to, prevent, impair or materially delay the ability of AT&T or Comcast or
     any of their respective Subsidiaries to consummate the transactions
     contemplated by this Agreement and the other Transaction Agreements; or

          (xxv) agree or commit to do any of the foregoing; provided that the
     limitations set forth in Sections 8.01(d)(i) through 8.01(d)(xxii) shall
     not apply to any transaction between AT&T Broadband and any wholly owned
     AT&T Broadband Subsidiary or between AT&T (to the extent not relating to
     the AT&T Broadband Group) and any wholly owned AT&T Subsidiaries (other
     than AT&T Broadband and any AT&T Broadband Subsidiaries) and provided,
     further, that the limitations set forth in Sections 8.01(d)(i) through
     8.01(d)(xxii) shall not be deemed to in any way apply to or prohibit any
     Excepted Transaction or any transaction by or involving AT&T and its
     wholly owned Subsidiaries if AT&T (to the extent relating to the AT&T
     Broadband Group), the AT&T Broadband Group, AT&T Broadband and the AT&T
     Broadband Subsidiaries are not bound thereby, such transaction does not
     involve AT&T (to the extent relating to the AT&T Broadband Group), the
     AT&T Broadband Group, AT&T Broadband or any of the AT&T Broadband
     Subsidiaries and such transaction would not otherwise adversely affect the
     transactions contemplated hereby in any material respect. In no event will
     AT&T enter into, or permit the AT&T Broadband Group, AT&T Broadband or any
     AT&T Broadband Subsidiary to enter into, any agreement or contract that
     would bind or purport to bind, Parent or any of its Affiliates (other than
     AT&T Broadband and the AT&T Broadband Subsidiaries) after the Effective
     Time.

     SECTION 8.02. AT&T Shareholders' Meeting; Proxy Material. (a) Subject to
applicable law, AT&T shall cause the AT&T Shareholders' Meeting to be duly
called and held as soon as reasonably practicable (taking into consideration
all relevant factors, including delays due to complications of preparing
required pro forma and other Financial statements) for the purpose of voting on
proposals in respect of each of the AT&T Shareholders' Approvals; provided,
however, that if within five days of the time the parties are notified by the
SEC that it is willing to declare the Registration Statement effective any
conditions shall exist (such


                                      A-90



conditions, the "Mandatory Residual Conditions") such that, as a result of the
AT&T Transaction Approval being obtained, the holders of the Senior Notes would
be entitled to require AT&T or any of its Affiliates to repurchase all or any
portion of the Senior Notes, then AT&T shall be entitled to delay the calling
of the AT&T Shareholders' Meeting until such time as the Mandatory Residual
Conditions no longer exist. In connection with the AT&T Shareholders' Meeting,
AT&T will (i) subject to Section 8.02(b), use its reasonable best efforts to
obtain each of the AT&T Shareholders' Approvals and (ii) otherwise comply with
all legal requirements applicable to AT&T Shareholders' Meeting.

     (b) Except as provided below, AT&T's Board of Directors shall recommend
approval of each of the proposals in respect of the AT&T Shareholders'
Approvals by AT&T shareholders. AT&T's Board of Directors shall be permitted to
withdraw, or modify in a manner adverse to Comcast, its recommendations to AT&T
shareholders only if (i) AT&T has complied with the terms of Section 8.03,
including the requirement in Section 8.03(d) that it notify Comcast promptly
after its receipt of any AT&T Broadband Acquisition Proposal; (ii) AT&T's Board
of Directors determines in good faith by a majority vote, after consulting with
AT&T's outside counsel, that it must take such action to comply with its
fiduciary duties under applicable law; and (iii) AT&T shall have delivered to
Comcast a prior written notice advising Comcast that it intends to take such
action and describing its reasons for taking such action (such notice to be
delivered not less than two Business Days prior to the time such action is
taken). Unless this Agreement shall have been terminated in accordance with its
terms, subject to applicable law, AT&T shall submit proposals in respect of
each of the AT&T Shareholders' Approvals at the AT&T Shareholders' Meeting even
if AT&T's Board of Directors determines at any time after the date hereof that
this Agreement and the transactions contemplated hereby or the Parent Charter
to be implemented at the Effective Time, including the corporate governance
provisions included therein, are no longer advisable or recommends that AT&T
shareholders reject either of the proposals in respect of the AT&T
Shareholders' Approvals.

     SECTION 8.03. No Solicitation. (a) From the date hereof until the
termination hereof, AT&T will not, and will cause the AT&T Subsidiaries and the
officers, directors, employees, investment bankers, attorneys, accountants,
consultants or other agents, representatives or advisors of AT&T and the AT&T
Subsidiaries not to, directly or indirectly (i) take any action to solicit,
initiate, facilitate or encourage the submission of any AT&T Broadband
Acquisition Proposal; (ii) subject to Section 8.03(e), engage in any
discussions or negotiations with, or disclose any non-public information
relating to AT&T (to the extent relating to the AT&T Broadband Group), the AT&T
Broadband Group, AT&T Broadband or any AT&T Broadband Subsidiary or afford
access to the properties, books or records of AT&T (to the extent relating to
the AT&T Broadband Group),


                                      A-91



the AT&T Broadband Group, AT&T Broadband or any AT&T Broadband Subsidiary to,
any Person who is known by AT&T to be considering making, or has made, an AT&T
Broadband Acquisition Proposal; (iii)(A) amend or grant any waiver or release
under any standstill agreement, agreement restricting a party from engaging in
negotiations or discussions with other parties or any similar agreement with
respect to any class of equity securities of AT&T (other than in connection
with an Excepted Transaction) or with respect to the AT&T Broadband Group or
any of its material assets or (B) approve any transaction, or approve of any
Person becoming an "Interested Shareholder", under Section 912 of the NYBCL or
Section 203 of the DGCL; or (iv) enter into any agreement with respect to an
AT&T Broadband Acquisition Proposal (other than a confidentiality agreement as
described below).

     (b) Notwithstanding the provisions of Section 8.03(a) or any other
provision of this Agreement, prior to the AT&T Shareholders' Meeting, AT&T may,
in response to an unsolicited bona fide AT&T Broadband Acquisition Proposal
that AT&T's Board of Directors determines in good faith, by majority vote,
after consultation with its Financial advisors and outside legal counsel, would
reasonably be expected to lead to an AT&T Superior Proposal, furnish
confidential or nonpublic information and access to, and engage in discussions
and negotiate with, such Person making such proposal; provided that prior to
taking any of such actions, (i) AT&T has complied with the terms of this
Section 8.03, including the requirement in Section 8.03(d) that it notify
Comcast promptly after its receipt of any AT&T Broadband Acquisition Proposal,
(ii) the AT&T Board of Directors determines in good faith, by majority vote,
after consultation with AT&T's outside legal counsel that it must take such
action to comply with its Fiduciary duties under applicable law and (iii) such
Person making such proposal executes a confidentiality agreement with terms no
less favorable in the aggregate to AT&T than those contained in the AT&T
Confidentiality Agreement. "AT&T Superior Proposal" means an unsolicited, bona
Fide AT&T Broadband Acquisition Proposal that AT&T's Board of Directors
determines in good faith, after consultation with its Financial advisors and
outside legal counsel and taking into account all the terms and conditions of
the AT&T Broadband Acquisition Proposal, including the likelihood and timing of
consummation of the AT&T Broadband Acquisition Proposal (including, without
limitation, the likelihood of obtaining financing and receiving necessary
regulatory approvals), would be more favorable to the holders of AT&T Common
Stock than the transactions provided for in this Agreement.

     (c) Nothing contained in this Agreement shall prevent AT&T's Board of
Directors from complying with Rule 14e-2 and Rule 14d-9 under the 1934 Act with
regard to an AT&T Broadband Acquisition Proposal; provided that AT&T's Board of
Directors shall not recommend that AT&T shareholders tender their


                                      A-92



shares in connection with a tender offer, except to the extent AT&T's Board of
Directors by a majority vote determines in its good faith judgment that such a
recommendation is required to comply with the Fiduciary duties of AT&T's Board
of Directors under applicable law, after consulting with outside legal counsel.

     (d) AT&T will notify Comcast promptly (but in no event later than 24
hours) after receipt by AT&T (or any of its advisors) of any AT&T Broadband
Acquisition Proposal, or of any request for nonpublic information relating to
AT&T (to the extent relating to the AT&T Broadband Group), the AT&T Broadband
Group, AT&T Broadband or any AT&T Broadband Subsidiary or for access to the
properties, books or records of AT&T (to the extent relating to the AT&T
Broadband Group), the AT&T Broadband Group, AT&T Broadband or any AT&T
Broadband Subsidiary by any Person who is known to be considering making, or
has made, an AT&T Broadband Acquisition Proposal. AT&T shall provide such
notice orally and in writing and shall identify the Person making, and the
terms and conditions of, any such AT&T Broadband Acquisition Proposal,
indication or request. AT&T shall keep Comcast fully informed, on a prompt
basis (but in any event no later than 24 hours), of the status and details of
any such AT&T Broadband Acquisition Proposal, indication or request. AT&T
shall, and shall cause the AT&T Subsidiaries and the directors, employees and
other agents of AT&T and the AT&T Subsidiaries to, cease immediately and cause
to be terminated all activities, discussions or negotiations, if any, with any
Persons conducted prior to the date hereof with respect to any AT&T Broadband
Acquisition Proposal. This Section 8.03(d) shall not apply with respect to any
Excepted Transaction; provided that if an agreement is entered into with
respect to an Excepted Transaction that would reasonably be expected to delay
the transactions contemplated hereby, AT&T shall promptly thereafter notify
Comcast of such agreement and provide Comcast with information it may
reasonably request relating to such Excepted Transaction to the extent it is
relevant to the transactions contemplated hereby.

     (e) Notwithstanding anything in Section 8.03 to the contrary, in
connection with discussions or negotiations relating to a proposed Excepted
Transaction, AT&T may (i) disclose non-public information relating to AT&T (to
the extent relating to the AT&T Broadband Group), the AT&T Broadband Group,
AT&T Broadband or any AT&T Broadband Subsidiary and (ii) afford access to the
properties, books or records of AT&T (to the extent relating to the AT&T
Broadband Group), the AT&T Broadband Group, AT&T Broadband or any AT&T
Broadband Subsidiary, in the case of (i) and (ii), to the Person or Persons
with whom AT&T is engaged in such discussions or negotiations relating to such
proposed transaction; provided that (x) such Person or Persons (A) are not
known by AT&T to be considering making, or to have made, an AT&T Broadband


                                      A-93



Acquisition Proposal and (B) execute a confidentiality agreement with AT&T
Broadband with confidentiality terms no less favorable than those in the AT&T
Confidentiality Agreement pursuant to which such Person or Persons agree to
hold any information relating to AT&T (to the extent relating to the AT&T
Broadband Group), the AT&T Broadband Group, AT&T Broadband and any AT&T
Broadband Subsidiary confidential and (y) such disclosure and such access are
limited to that reasonably necessary in connection with such proposed
transaction.

     SECTION 8.04. Ancillary Agreements. Subject to the terms and conditions of
this Agreement, the Separation and Distribution Agreement and the other
Ancillary Agreements, AT&T shall, and shall cause each of its Subsidiaries
(which, after the Effective Time, shall not include any of the AT&T Broadband
Entities) to, comply with its respective obligations under the Separation and
Distribution Agreement and the other Ancillary Agreements pursuant to and in
accordance with the terms thereof. No provision of the Separation and
Distribution Agreement or any of the other Ancillary Agreements may be amended
or waived prior to the Effective Time without the prior written consent of
Comcast, except that the Primary Commercial Agreements and the Additional
Commercial Agreements may be amended or waived in the ordinary course of
business without the prior written consent of Comcast if such amendment or
waiver would not be adverse in any material respect to AT&T (to the extent
relating to the AT&T Broadband Group), the AT&T Broadband Group, AT&T Broadband
or any of the AT&T Broadband Subsidiaries. None of the Separation and
Distribution Agreement and the other Ancillary Agreements may be terminated
prior to the Effective Time without the prior written consent of Comcast. The
AT&T Broadband Group shall not grant any consent or approval under the
Separation and Distribution Agreement or any of the other Ancillary Agreements
prior to the Effective Time without the prior written concurrence of Comcast,
except that the AT&T Broadband Group may grant a consent or approval under any
Primary Commercial Agreement or Additional Commercial Agreement in the ordinary
course of business if such consent or approval would not be adverse in any
material respect to AT&T (to the extent relating to the AT&T Broadband Group),
the AT&T Broadband Group, AT&T Broadband or any of the AT&T Broadband
Subsidiaries. Any agreements entered into or documents executed pursuant to the
Primary Transaction Agreements shall be reasonably acceptable to Comcast. Prior
to the Effective Time, all determinations by the AT&T Broadband Group under the
Separation and Distribution Agreement or any of the other Ancillary Agreements
will be made for the benefit of the AT&T Broadband Group and, in the event of
any discretion as to terms, such terms shall be no less favorable to the AT&T
Broadband Group than arm's-length terms.


                                      A-94



     SECTION 8.05. Neutrality Agreement. Notwithstanding any other provision of
this Agreement, AT&T shall not renew, extend or modify the Neutrality and
Consent Election Agreement (the "Neutrality Agreement") among AT&T, the
Communications Workers of America and the International Brotherhood of
Electrical Workers, such that such agreement, as so renewed, extended or
modified, will apply to or otherwise bind or purport to apply to or otherwise
bind, after the Effective Time, AT&T Broadband, any of the AT&T Broadband
Subsidiaries, Parent, Comcast or any of the Comcast Subsidiaries, either as a
matter of contract or term or condition of employment. AT&T shall not enter
into any other agreement or arrangement with respect to the same or similar
matters as the matters covered by the Neutrality Agreement if such agreement or
arrangement would apply to or otherwise bind or purport to apply to or
otherwise bind, after the Effective Time, AT&T Broadband, any of the AT&T
Broadband Subsidiaries, Parent, Comcast or any of the Comcast Subsidiaries,
either as a matter of contract or term or condition of employment.

     SECTION 8.06. Broadband Employees. Prior to the Effective Time, AT&T
shall, and shall cause each of its Subsidiaries to, use reasonable best efforts
so that, immediately prior to the Effective Time, (i) all individuals (other
than Broadband Transferees) who are then primarily employed (whether actively
or then on an approved leave of absence) in connection with the AT&T Broadband
Business will be employed, as of the Effective Time, by the AT&T Broadband
Group and (ii) the AT&T Broadband Group will employ no individuals other than
those referred to in clause (i) of this Section 8.06 and the Broadband
Transferees; provided that no transfers required to implement this Section 8.06
shall result in any severance liabilities to AT&T Broadband.

     SECTION 8.07. AT&T Post-signing Equity Awards. With respect to any options
to purchase shares of AT&T Common Stock and any other equity-based awards based
upon shares of AT&T Common Stock granted by AT&T or any of its Subsidiaries
from the date hereof until the Effective Time, AT&T shall provide in the
agreements evidencing such awards that the transactions contemplated by this
Agreement or any of the other Transaction Agreements shall not constitute a
"Change in Control" for purposes of triggering accelerated vesting of the
awards; provided that if any employee who receives such an award is terminated
after the Effective Time under conditions entitling him to receive "Change in
Control Severance Benefits" under Appendix 2 of the AT&T Broadband Severance
Plan, the equity awards held by such employee shall become immediately vested
upon termination of employment and, if subject to exercise, shall remain
exercisable for the full extent of the original term of the award.

     SECTION 8.08. Redemption of TCI Pacific Preferred Stock. Prior to the
Effective Time, AT&T shall cause TCI Pacific Communications, Inc. (i) to call


                                      A-95



for redemption all of the outstanding shares of TCI Pacific Preferred Stock and
(ii) to the extent any of such shares are not exchanged for shares of AT&T
Common Stock prior to the applicable redemption date, to redeem all of such
shares remaining outstanding in exchange for shares of AT&T Common Stock, in
the case of each of (i) and (ii), in accordance with the terms of the
certificate of designation for the TCI Pacific Preferred Stock. The shares of
AT&T Common Stock used to effect the foregoing redemption or exchange shall be
provided by AT&T to TCI Pacific Communications, Inc. without payment of any
consideration or charge by TCI Pacific Communications, Inc. or the AT&T
Broadband Group.

     SECTION 8.09. Note Consent Process. AT&T will consult with Comcast in
connection with actions taken by AT&T in furtherance of satisfaction of the
condition specified in Section 10.01(l). AT&T will conduct such actions in a
manner reasonably designed to minimize the cost and expenses incurred in
connection with satisfaction of such condition. The parties agree that AT&T may
obtain Note Consents or otherwise satisfy the condition set forth in Section
10.01(l) by a one-time cash payment of a consent fee, through a coupon increase
or a combination thereof and that any costs and expenses incurred in connection
therewith (as calculated pursuant to Section 11.03) shall be shared pursuant to
Section 11.03(a)(iv). AT&T shall not be required to take any action other than
those referred to in the preceding sentence in order to satisfy the condition
set forth in Section 10.01(l) unless Comcast agrees that the costs and expenses
incurred in connection therewith shall be shared on the basis set forth in
Section 11.03(a)(iv).


                                   ARTICLE 9
                     COVENANTS OF AT&T, COMCAST AND PARENT

     SECTION 9.01. Best Efforts. (a) Subject to the terms and conditions of
this Agreement, each of the parties hereto will use its best efforts to
promptly (i) take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to consummate the Mergers and the other transactions contemplated
hereby as soon as practicable, including preparing and Filing as promptly as
practicable all documentation to effect all necessary Filings, notices,
petitions, statements, registrations, submissions of information, applications
and other documents and (ii) obtain and maintain all approvals, consents,
registrations, permits, authorizations and other confirmations required to be
obtained from any third Person that are necessary, proper or advisable to
consummate the Mergers and the other transactions contemplated hereby;
provided, that the parties' obligations to


                                      A-96



obtain the License Consents and the expiration (without either the Department
of Justice or the Federal Trade Commission obtaining any injunction or other
relief that prevents the consummation of the transactions contemplated hereby)
or termination of the applicable waiting periods under the HSR Act shall be
unconditional and shall not be qualified by best efforts. Consistent with its
obligations under the preceding sentence, Comcast and AT&T will commit to and
implement divestitures, hold separate or similar transactions or actions with
respect to assets or businesses of the Comcast Group and the AT&T Broadband
Group, which commitments and implementations may, at Comcast's or AT&T's
option, be conditioned upon and effective as of the Effective Time. No party
hereto shall, directly or indirectly, extend any waiting period under the HSR
Act or enter into any agreement with a Governmental Authority to delay or to
not consummate the Mergers or the other transactions contemplated by this
Agreement, except with the prior written consent of the other parties. The
parties' actions with respect to this paragraph shall be reasonable and
reasonably calculated to facilitate consummation of the Mergers by the End
Date. Subject to applicable law relating to the exchange of information,
Comcast and AT&T shall have the right to review in advance, and to the extent
practicable each will consult the other on, all the information relating to
Comcast and the Comcast Subsidiaries or AT&T and the AT&T Broadband
Subsidiaries, as the case may be, that appears in any Filing made with, or
written materials submitted to, any third party and/or any Governmental
Authority in connection with the Mergers and the other transactions
contemplated hereby. Prior to the date hereof, each of Comcast and AT&T has
provided to the other a list of all material Franchise Consents of such party,
all material License Consents of such party, all material PUC Consents of such
party and all rights that any Person may have under the terms of such party's
material Franchises to purchase all or any portion of a System owned and
operated by such party as a result of the transactions contemplated hereby
("Purchase Rights").

     (b) In furtherance and not in limitation of the foregoing, each of AT&T
and Comcast agrees to (i) make an appropriate Filing of a Notification and
Report Form pursuant to the HSR Act with respect to the Mergers and the other
transactions contemplated hereby as promptly as practicable (and, in any event,
within 45 calendar days of the date of this Agreement), (ii) supply as promptly
as practicable any additional information and documentary material that may be
requested pursuant to the HSR Act and (iii) complete the review process under
the HSR Act to permit the consummation of the Mergers and the other
transactions contemplated hereby, including causing the expiration or
termination of the applicable waiting periods under the HSR Act as soon as
practicable.

     SECTION 9.02. Joint Proxy Statement; Registration Statement. (a) As
promptly as practicable after the date hereof (and, in any event, within 60
calendar


                                      A-97



days of the date of this Agreement) the parties hereto shall prepare and File
the Joint Proxy Statement and the Registration Statement (in which the Joint
Proxy Statement will be included) with the SEC. AT&T and Comcast shall use
their reasonable best efforts to cause the Registration Statement to become
effective under the 1933 Act as soon after such Filing as practicable and to
keep the Registration Statement effective as long as is necessary to consummate
the Mergers. The Joint Proxy Statement shall include the recommendation of the
Board of Directors of Comcast in favor of approval of each of the proposals in
respect of the Comcast Shareholders' Approvals and the Preferred Structure
Approval and the recommendation of the Board of Directors of AT&T in favor of
approval of each of the proposals in respect of the AT&T Shareholders'
Approvals, except to the extent the Board of Directors of AT&T shall have
withdrawn or modified its approval or recommendation in favor of approval of
either of the proposals in respect of the AT&T Shareholders' Approvals as
permitted by Section 8.02(b). Comcast and AT&T each shall use its reasonable
best efforts to cause the Joint Proxy Statement to be mailed to its respective
shareholders as promptly as practicable after the Registration Statement
becomes effective. Each of Comcast and AT&T shall promptly provide copies,
consult with each other and prepare written responses with respect to any
written comments received from the SEC with respect to the Joint Proxy
Statement and the Registration Statement and advise one another of any oral
comments received from the SEC. The Registration Statement and the Joint Proxy
Statement shall comply as to form in all material respects with the rules and
regulations promulgated by the SEC under the 1933 Act and the 1934 Act,
respectively.

     (b) AT&T and Comcast shall make all necessary Filings with respect to the
Mergers and the transactions contemplated hereby under the 1933 Act and the
1934 Act and applicable state "blue sky" laws and the rules and regulations
thereunder. Each party hereto will advise the other parties, promptly after it
receives notice thereof, of the time when the Registration Statement has become
effective or any supplement or amendment has been Filed, the issuance of any
stop order, the suspension of the qualification of the Parent Common Stock
issuable in connection with the Mergers for offering or sale in any
jurisdiction, or any request by the SEC for amendment of the Joint Proxy
Statement or the Registration Statement or comments thereon and responses
thereto or requests by the SEC for additional information. No amendment or
supplement to the Joint Proxy Statement or the Registration Statement shall be
Filed without the approval of both AT&T and Comcast, which approval shall not
be unreasonably withheld or delayed. If, at any time prior to the Effective
Time, any information relating to AT&T or Comcast, or any of their respective
Affiliates, officers or directors should be discovered by AT&T or Comcast that
should be set forth in an amendment or supplement to the Registration Statement
or the Joint Proxy Statement so that such documents would not include any
misstatement of a


                                      A-98



material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, the party hereto that discovers such information shall promptly
notify the other parties hereto and an appropriate amendment or supplement
describing such information shall be promptly Filed with the SEC and, to the
extent required by law, disseminated to the shareholders of AT&T and Comcast.

     SECTION 9.03. Public Announcements. So long as this Agreement is in
effect, Comcast and AT&T will consult with each other before issuing any press
release or making any public statement with respect to this Agreement or the
transactions contemplated hereby and, except as may be required by applicable
law or any listing agreement with any national securities exchange or quotation
system, will not issue any such press release or make any such public statement
without the prior consent of the other, which consent shall not be unreasonably
withheld. Notwithstanding the foregoing, any such press release or public
statement that may be required by applicable law or any listing agreement with
any national securities exchange or quotation system may be issued without such
consent, if the party hereto making such release or statement has used its
reasonable best efforts to consult with the other parties.

     SECTION 9.04. Further Assurances. At and after the Effective Time, the
officers and directors of the applicable Surviving Corporation will be
authorized to execute and deliver, in the name and on behalf of AT&T Broadband
or Comcast, as the case may be, any deeds, bills of sale, assignments or
assurances and to take and do, in the name and on behalf of AT&T Broadband or
Comcast, as the case may be, any other actions and things to vest, perfect or
confirm of record in such Surviving Corporation, any and all right, title and
interest in, to and under any of the rights, properties or assets of AT&T
Broadband or Comcast, as the case may be, acquired or to be acquired by such
Surviving Corporation, as a result of or in connection with the applicable
Merger.

     SECTION 9.05. Access to Information. From the date hereof until the
Effective Time or earlier termination of this Agreement and subject to
applicable law and the Confidentiality Agreements, each of Comcast and AT&T
shall (a) give to the other and the other's legal counsel, Financial advisors,
auditors and other authorized representatives reasonable access during normal
business hours to the offices, properties, books and records of such party and
its Subsidiaries, (b) furnish to the other and the other's counsel, Financial
advisors, auditors and other authorized representatives such Financial and
operating data and other information as such Persons may reasonably request and
(c) instruct its employees, legal counsel, Financial advisors, auditors and
other authorized representatives to cooperate with the other in such other
party's investigation. Any investigation pursuant to this Section 9.05 shall be
conducted in a manner as not


                                      A-99



to interfere unreasonably with the conduct of the business of the party being
investigated. No information or knowledge obtained in any investigation
pursuant to this Section 9.05 shall affect or be deemed to modify any
representation or warranty made by any party hereunder. Each party hereto will
hold such information that is non-public in confidence in accordance with the
provisions of the applicable Confidentiality Agreement.

     SECTION 9.06. Tax-free Transactions. (a) Prior to the Effective Time, each
party hereto shall use its best efforts to cause the Mergers to qualify as
tax-free exchanges described in Section 351 of the Code ("351 Transactions"),
and will not take any action reasonably likely to cause the Mergers not to so
qualify.

     (b) Prior to the Effective Time, each party hereto shall use its best
efforts to (i) cause the Separation and Distribution to qualify as tax-free
transactions pursuant to Sections 355 and 368(a) of the Code, and will not take
any action reasonably likely to cause the Separation and Distribution not to so
qualify and (ii) ensure that the Mergers will not cause the Separation and
Distribution to fail to be qualified as tax-free transactions pursuant to
Sections 355 and 368(a) of the Code.

     (c) Each party hereto shall use its best efforts to obtain (i) the ruling
or opinion referred to in Section 10.01(j) and (ii) the opinions referred to in
Sections 10.02(b) and 10.03(b).

     SECTION 9.07. Affiliates. (a) Within 30 days following the date of the
AT&T Shareholders' Meeting, AT&T shall deliver to Comcast a letter identifying
all known Persons who may be deemed affiliates of AT&T Broadband under Rule 145
of the 1933 Act (an "AT&T Rule 145 Affiliate"). AT&T shall use its reasonable
best efforts to obtain and deliver to Comcast a written agreement from each
AT&T Broadband Rule 145 Affiliate as soon as practicable and, in any event,
prior to the Effective Time, substantially in the form attached as Exhibit B.

     (b) Within 30 days following the date of the Comcast Shareholders'
Meeting, Comcast shall deliver to AT&T a letter identifying all known Persons
who may be deemed affiliates of Comcast under Rule 145 of the 1933 Act (an
"Comcast Rule 145 Affiliate"). Comcast shall use its reasonable best efforts to
obtain and deliver to AT&T a written agreement from each Comcast Rule 145
Affiliate as soon as practicable and, in any event, prior to the Effective
Time, substantially in the form attached as Exhibit B.

     SECTION 9.08. Governance and Other Matters. Parent shall take all actions
necessary so that at the Effective Time the Parent Board of Directors shall


                                     A-100



consist of 12 directors, five (5) of whom shall be then-existing Comcast
directors designated by Comcast, five (5) of whom shall be then-existing AT&T
directors designated by AT&T and two (2) of whom shall be Independent Persons
jointly designated by Comcast and AT&T. Except as set forth on the Comcast
Disclosure Schedule or the AT&T Disclosure Schedule, the individuals designated
to be members of the Parent Board of Directors shall be mutually agreed by
Comcast and AT&T. The senior officers of Parent at the Effective Time shall be
designated by the chief executive officer of Comcast in consultation with the
chief executive officer of AT&T. Until Parent's 2005 annual meeting of
shareholders, Parent shall maintain an executive office in the New York City
metropolitan area. The headquarters for Parent shall initially be in
Philadelphia, Pennsylvania.

     SECTION 9.09. Notices of Certain Events. Each of Comcast and AT&T shall
promptly notify the other of:

     (a) any notice or other communication from any Person alleging that the
consent of such Person is or may be required in connection with the
transactions contemplated hereby;

     (b) any notice or other communication from any Governmental Authority in
connection with the transactions contemplated hereby;

     (c) the occurrence, or nonoccurrence, of any event the occurrence, or
nonoccurrence, of which would reasonably be expected to cause any
representation or warranty contained herein to be untrue or inaccurate in any
material respect at any time during the period commencing on the date hereof
and ending at the Effective Time; and

     (d) any failure of such party to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section
9.09 shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

     SECTION 9.10. Section 16 Matters. Prior to the Effective Time, Comcast,
AT&T and AT&T Broadband shall take all such actions as may be required to cause
any (i) dispositions of AT&T Common Stock or AT&T Broadband Common Stock
(including derivative securities with respect to AT&T Common Stock or AT&T
Broadband Common Stock) or Comcast Common Stock (including derivative
securities with respect to Comcast Common Stock) or (ii) acquisitions of Parent
Common Stock (including derivative securities with respect to Parent Common
Stock) resulting from the transactions contemplated by this Agreement by each
individual who is subject to the reporting requirements of


                                     A-101



Section 16(a) of the 1934 Act with respect to AT&T, AT&T Broadband or Comcast,
or will become subject to such reporting requirements with respect to Parent,
to be exempt under Rule 16b-3 promulgated under the 1934 Act.

     SECTION 9.11. Director and Officer Liability. (a) Parent shall indemnify
and hold harmless and advance expenses to the present and former officers and
directors of AT&T, the AT&T Subsidiaries, AT&T Broadband, the AT&T Broadband
Subsidiaries, Comcast and the Comcast Subsidiaries, and each individual who
prior to the Effective Time becomes an officer or director of AT&T, an AT&T
Subsidiary, AT&T Broadband, an AT&T Broadband Subsidiary, Comcast or a Comcast
Subsidiary (each an "Indemnified Person"), in respect of acts or omissions by
them in their capacities as such occurring at or prior to the Effective Time
(including for acts or omissions occurring in connection with this Agreement
and the consummation of the transactions contemplated hereby) to the maximum
extent permitted by law ("Indemnified Losses"); provided that notwithstanding
the foregoing Parent shall have no obligation to indemnify and hold harmless
and advance expenses to any Indemnified Person in respect of acts or omissions
of such Indemnified Person that occurred while such Indemnified Person was
acting in a capacity for AT&T and its Subsidiaries other than in connection
with either the AT&T Broadband Group or this Agreement and the transactions
contemplated hereby; provided, further, that AT&T shall indemnify and hold
harmless Parent for 50% of any Indemnified Losses arising out of acts or
omissions of the AT&T officers and directors in connection with this Agreement
and the consummation of the transactions contemplated hereby. Without limiting
the generality of the foregoing, the Indemnified Losses shall include
reasonable costs of prosecuting a claim under this Section 9.11(a). Parent
shall periodically advance or reimburse each Indemnified Person for all
reasonable fees and expenses of counsel constituting Indemnified Losses as such
fees and expenses are incurred; provided that such Indemnified Person shall
agree to promptly repay to Parent the amount of any such reimbursement if it
shall be judicially determined by judgment or order not subject to further
appeal or discretionary review that such Indemnified Person is not entitled to
be Indemnified by Parent in connection with such matter. In the event that
Parent sells, transfers or leases all or substantially all of its assets or is
not a surviving corporation in any merger, consolidation or other business
combination in which it may enter with any Person, Parent shall, as a condition
of any such transaction, cause such purchaser or such surviving corporation, as
the case may be, to assume Parent's obligations under this Section 9.11 upon
the consummation of any such transaction.

     (b) For six years after the Effective Time, Parent shall provide or shall
cause each of the Surviving Corporations to provide officers' and directors'
liability insurance in respect of acts or omissions occurring prior to the
Effective


                                     A-102



Time (including for acts or omissions occurring in connection with this
Agreement and the consummation of the transactions contemplated hereby),
covering each such Indemnified Person (but, in the case of officers and
directors of AT&T and its Subsidiaries, only in respect of acts or omissions of
such person acting in connection with the AT&T Broadband Group or this
Agreement and the transactions contemplated hereby) currently covered by the
officers' and directors' liability insurance policy of AT&T or Comcast, as the
case may be, on terms with respect to coverage and amount (including with
respect to the payment of attorneys' fees) no less favorable than those of such
policy in effect on the date hereof; provided that, if the aggregate annual
premiums for such insurance during such period shall exceed 300% of the per
annum rate of premium paid by either AT&T or Comcast as of the date hereof for
such insurance, then Parent shall provide or cause to be provided a policy for
the applicable individuals with the best coverage as shall then be available at
300% of such rate (it being agreed that in the event that Parent or its
Affiliate shall pay premiums in excess of such rate in order to cover directors
or officers of one such entity, it shall pay premiums at such higher rate to
cover directors or officers of the other such entity).

     (c) The rights of each Indemnified Person and his or her heirs and legal
representatives under this Section 9.11 shall be in addition to any rights such
Indemnified Person may have under the certificate of incorporation or bylaws of
AT&T, any AT&T Subsidiary, AT&T Broadband, any AT&T Broadband Subsidiary,
Comcast or any Comcast Subsidiary, or under the PBCL, the NYBCL, the DGCL or
any other applicable law.

     SECTION 9.12. Listing of Stock. Comcast and Parent shall use their
respective reasonable best efforts to cause the shares of Parent Class A Common
Stock and the Parent Class A Special Common Stock (and, if applicable, Parent
Class C Common Stock) to be issued in connection with the Mergers and reserved
for issuance in connection with the AT&T Stock Options, the AT&T Equity Awards,
the Comcast Options and the Comcast Equity Awards to be approved for listing on
Nasdaq subject to official notice of issuance.

     SECTION 9.13. Employee Matters. (a) Parent shall and shall cause its
Subsidiaries (including the AT&T Broadband Surviving Corporation and the
Comcast Surviving Corporation) to:

          (i) honor the terms of all Broadband Employee Plans and Broadband
     Benefit Arrangements, and to pay or provide, or cause its Subsidiaries to
     pay or provide, the benefits required thereunder, recognizing that the
     consummation of the transactions contemplated hereby will constitute a
     "change in control" for purposes of the Broadband Employee Plans and
     Broadband Benefit Arrangements that include a


                                     A-103



     provision for modifications to benefits in the event of a "change in
     control";

          (ii) until December 31, 2003 (the "Benefits Maintenance Period"),
     with respect to Broadband Employees (other than those subject to
     collective bargaining obligations or agreements), provide a level of
     aggregate employee benefits and compensation, taking into account all
     Employee Plans and Benefit Arrangements and other programs sponsored or
     maintained by AT&T and the AT&T Subsidiaries listed in Section 6.18(a) of
     the AT&T Disclosure Schedule to the extent they remain in effect, but
     excluding any severance, separation, or similar plan, program, policy or
     arrangement ("Severance Plans") that is substantially comparable in the
     aggregate to the aggregate employee benefits and compensation provided,
     with respect to service to AT&T Broadband or any of the AT&T Broadband
     Subsidiaries, to the Broadband Employees immediately prior to the
     Effective Time (excluding benefits provided under any Severance Plans);
     and

          (iii) until December 31, 2003, continue, without any change adverse
     to Broadband Employees, each severance plan identified in Section 6.18(a)
     of the AT&T Disclosure Schedule (the "AT&T Severance Plans").

     (b) If Broadband Employees are included in any Employee Plan, Benefit
Arrangement or International Plan sponsored or maintained by Parent or any of
its Subsidiaries following the Effective Time, the Broadband Employees shall
receive credit for service with AT&T and the AT&T Subsidiaries and their
predecessors prior to the Effective Time to the same extent and for the same
purposes thereunder as such service was counted under similar predecessor
Employee Plans and Benefit Arrangements for all purposes (except that, with
respect to benefit accrual, such service shall not be counted to the extent
that it would result in a duplication of benefits and shall not be counted for
purposes of benefit accrual under any defined benefit plan); provided, however,
that service with respect to Broadband Employees subject to collective
bargaining agreements or obligations shall be determined under such collective
bargaining agreements or obligations. Notwithstanding the foregoing, as soon as
practicable after the Benefits Maintenance Period, Broadband Employees who
satisfy eligibility requirements shall be allowed to participate in any
retirement medical or life insurance benefit plan then sponsored or maintained
by Parent or any of its Subsidiaries. If Broadband Employees or their
dependents are included in any medical, dental or health plan (a "Successor
Plan") other than the plan or plans in which they participated immediately
prior to the Effective Time (a "Prior Plan"), any such Successor Plan shall not
include any restrictions or limitations with


                                     A-104



respect to pre-existing condition exclusions or any actively-at-work
requirements (except to the extent such exclusions were applicable under any
similar Prior Plan at the Effective Time) and any eligible expenses incurred by
any Broadband Employee and his or her covered dependents during the portion of
the plan year of such Prior Plan ending on the date such employee's
participation in such Successor Plan begins shall be taken into account under
such Successor Plan for purposes of satisfying all deductible, coinsurance and
maximum out-of-pocket requirements applicable to such Broadband Employee and
his or her covered dependents for the applicable plan year as if such amounts
had been paid in accordance with such Successor Plan. Without limiting the
generality of the foregoing, for purposes of determining severance pay and
benefits under any applicable Broadband Severance Plan or other Severance Plan
covering a Broadband Employee at or after the Effective Time, each Broadband
Employee shall receive credit for service prior to the Effective Time with AT&T
and the AT&T Subsidiaries and their predecessors to the same extent and for the
same purposes as such service was counted under the applicable Broadband
Severance Plans as in effect before the Effective Time, as well as for service
from and after the Effective Time with Parent and any of its Subsidiaries
(including the AT&T Broadband Surviving Corporation and the Comcast Surviving
Corporation).

     (c) As soon as practicable after the Effective Time, Parent shall offer a
one-time grant of options to purchase a number of shares of Parent Common Stock
equal to 300 multiplied by the Exchange Ratio to each full-time employee of
Parent or any of its Subsidiaries (excluding any employee of a non-wholly owned
Comcast Subsidiary if the applicable subsidiary was a non-wholly owned Comcast
Subsidiary prior to the Effective Time, but including, for the avoidance of
doubt, each Broadband Employee).

     (d) Except as otherwise specifically set forth above, nothing contained
herein shall be construed as requiring Parent or any of its Subsidiaries to
continue any specific Employee Plan or Benefit Arrangement, or to continue the
employment of any specific person; provided, however, that any changes that
Parent or any of its Subsidiaries may make to any such Employee Plan or Benefit
Arrangement are permitted by the terms of the applicable Employee Plan or
Benefit Arrangement and under any applicable law.

     SECTION 9.14. Employment Agreements. Parent shall offer to enter into an
employment agreement, effective as of the Effective Time, with each of Mr.
Brian L. Roberts, Mr. Ralph J. Roberts and Mr. C. Michael Armstrong, in each
case on substantially the same terms as his existing employment agreement with
Comcast or AT&T, as the case may be, except that (a) "Parent" shall be
substituted for "Comcast" or "AT&T", as the case may be, wherever such term
appears in his existing employment agreement, (b) such additional concomitant


                                     A-105



adjustments as may be necessary to reflect the foregoing shall be made, (c)
such additional changes to reflect the provisions with respect to governance
set forth in the Parent Charter shall be made and (d) the term of the
employment agreement shall be extended to terminate no earlier than the date of
the annual meeting of shareholders of Parent in 2005.

     SECTION 9.15. Interim Finance Committee. (a) The parties agree promptly to
establish an Interim Finance Committee, comprised of Lawrence S. Smith (or if
he is unavailable to serve, another senior officer of Comcast appointed by
Comcast) and Charles Noski (or if he is unavailable to serve, another senior
officer of AT&T Broadband appointed by AT&T) for the purpose of engaging in
Financial planning for AT&T Broadband. The Interim Finance Committee will seek
to arrange Financing (the "Financing") in an amount sufficient to (a) pay to
AT&T at the Effective Time an amount equal to any Indebtedness owed by any AT&T
Broadband Entity to AT&T or any of its Subsidiaries (other than any AT&T
Broadband Entity) at such time (including, if applicable, the intercompany
Indebtedness referred to in Section 9.18), (b) refinance any of the TOPRS that
will be called for redemption at the Effective Time or shortly thereafter and
(c) provide appropriate cash reserves to fund the operations of AT&T Broadband
after the Effective Time, including the costs and expenses of AT&T Broadband
under Section 11.03(a). In the event the Interim Finance Committee agrees upon
the Financing, Comcast shall use its reasonable best efforts to arrange for the
Financing on the terms agreed by the Interim Finance Committee. In the event
Comcast is unable to obtain the Financing so agreed upon by the Interim Finance
Committee or the Interim Finance Committee does not agree upon the Financing,
Comcast shall arrange for a senior credit facility with a term not exceeding
five years to provide the Financing. The Interim Finance Committee may consult
with Financial advisors to the extent it deems necessary or advisable.

     (b) The Interim Finance Committee shall also have responsibility for
monitoring AT&T's progress in obtaining the Note Consents and in taking other
actions in furtherance of the satisfaction of the condition specified in
Section 10.01(l). At the request of AT&T, the Interim Finance Committee shall
give due consideration to any request made by AT&T that Comcast share in costs
and expenses incurred by AT&T in connection with an exchange offer, a tender
offer, a defeasance or other action proposed by AT&T in furtherance of
satisfaction of the condition specified in Section 10.01(l). After such
consideration, the Interim Finance Committee shall deliver a recommendation to
Comcast of the portion (if any) of the costs and expenses that the Interim
Finance Committee reasonably believes represents Comcast's equitable share of
the costs and expenses that would be incurred in connection with such action.
Comcast shall give due consideration to the recommendation of the Interim
Finance Committee but shall


                                     A-106



have no obligation to pay AT&T for any of such costs and expenses unless
Comcast expressly consents thereto in writing. Any expenses that Comcast so
expressly consents to pay shall, to the extent incurred, be treated as costs of
obtaining Note Consents for purposes of this Section 9.15(b) and Section
11.03(a). The costs and expenses of obtaining the Note Consents shall be paid
for by AT&T except as provided in Section 11.03(a).

     SECTION 9.16. TOPRS. (a) Subject to Section 9.16(d), at the Effective
Time, Parent shall (i) call for redemption each series of TOPRS that is
redeemable in accordance with its terms at the Effective Time and as to which
AT&T has guaranteed the obligations of the applicable Subsidiary Trust, issuer
or other obligor, (ii) cause AT&T to be released from any such guarantee of the
obligations of the applicable Subsidiary Trust, issuer or other obligor in
respect of such series or (iii) comply with Section 9.16(d) with respect to
such series.

     (b) Subject to Section 9.16(d), with respect to any series of TOPRS that
is not redeemable in accordance with its terms at the Effective Time and as to
which AT&T has guaranteed the obligations of the applicable Subsidiary Trust,
issuer or other obligor, Parent shall (i) redeem, or cause to be redeemed, such
series of TOPRS on the earliest date on which such TOPRS may be redeemed in
accordance with their terms, (ii) cause AT&T to be released from any such
guarantee of the obligations of the applicable Subsidiary Trust, issuer or
other obligor on such date in respect of such series or (iii) comply with
Section 9.16(d) with respect to such series on such date.

     (c) The parties shall reasonably cooperate prior to the Effective Time in
connection with the transactions contemplated by this Section 9.16.

     (d) If Parent does not comply with its obligations under Section
9.16(a)(i) or (ii) or Section 9.16(b)(i) or (ii), then with respect to each
series as to which it has failed to so comply, it will post, or cause to be
posted at the applicable time set forth above, a letter of credit from a United
States Financial institution reasonably acceptable to AT&T containing the terms
contemplated hereby and otherwise in form and substance reasonably acceptable
to AT&T (including any renewals thereof, the "Letter of Credit"). The term of
the initial Letter of Credit shall be no less than one year. Prior to the 60
days prior to the expiration of any Letter of Credit, Parent shall renew or
extend, or cause to be renewed or extended, the Letter of Credit for at least
one additional year. AT&T shall be entitled to draw under any Letter of Credit
if AT&T makes any payment in respect of its guarantees relating to the TOPRS or
if any Letter of Credit is not renewed at least 60 days prior to the expiration
thereof on the terms contemplated by this Section. The face amount of each
Letter of Credit shall at all times be no less than the combined monetary
liabilities under guarantees with respect to the


                                     A-107



principal amount of notes held by the applicable trust of all series of TOPRS
as to which Parent has not complied with Section 9.16(a)(i) or (ii) or Section
9.16(b)(i) or (ii) above and as to which AT&T has guaranteed (A) the
obligations of the applicable Subsidiary Trust, issuer or other obligor with
respect to such unredeemed TOPRS and (B) the obligations of AT&T Broadband, LLC
or MediaOne Group, Inc., as applicable, as "Sponsor" pursuant to the
declaration of trust applicable to the issuing Subsidiary Trust. The obligation
of Parent to post, or cause to be posted, the Letter of Credit shall terminate
with respect to any portion of the TOPRS with respect to which any guarantee of
AT&T is fully, irrevocably and unconditionally released and discharged, whether
as a result of refinancing or otherwise. Upon the posting, if any, of the
Letter of Credit, Parent shall provide AT&T with copies of all documentation
relating to such Letter of Credit and all such documentation shall be in form
and substance reasonably satisfactory to AT&T.

     SECTION 9.17. Consideration. AT&T and Comcast acknowledge and agree that
the grant by AT&T Broadband of the rights pursuant to Section 2.11 of the
Separation and Distribution Agreement and the assumption by AT&T Broadband of
the deferred tax liability pursuant to Section 3.7(f) of the Tax Sharing
Agreement constitute a portion of the consideration payable in respect of the
AT&T Broadband Group's interest in TWE.

     SECTION 9.18. QUIPS. (a) If on the date that would otherwise be the
Closing Date the QUIPS Exchange does not occur (such date, the "QUIPS Failure
Date"), then subject to Section 9.18(c), the Closing Date shall be delayed as
provided in this Section 9.18. Following the QUIPS Failure Date, AT&T and
Comcast will use their commercially reasonable efforts to consummate the QUIPS
Exchange. If Microsoft thereafter agrees to consummate the QUIPS Exchange, then
subject to the QUIPS Exchange occurring on the Closing Date, the Closing Date
shall occur on the earliest date practicable or, if on such date all conditions
to the Mergers set forth in Article 10, other than conditions that by their
nature are to be satisfied at the Effective Time, are not satisfied or (to the
extent permissible) waived, on the earliest date after such date on which all
such conditions are satisfied or (to the extent permissible) waived unless this
Agreement is previously terminated in accordance with its terms.

     (b) In the event that the Closing Date does not occur within thirty (30)
days of the QUIPS Failure Date, AT&T may for a period of fifteen (15) calendar
days commencing on such 30th day elect to terminate this Agreement by giving
two Business Days' written notice to Comcast of its intent to terminate this
Agreement pursuant to this Section 9.18(b). Notwithstanding the foregoing,
AT&T's notice to terminate this Agreement pursuant to this Section 9.18(b)
shall not be effective if, prior to the expiration of such two Business Day
period,


                                     A-108



Comcast delivers a written notice pursuant to and in accordance with the second
sentence of Section 9.18(c) (which notice complies with the proviso thereof),
unless Comcast fails to close within 60 days of the QUIPS Failure Date, in
which event AT&T shall be entitled to terminate this Agreement.

     (c) If the Closing Date has not occurred pursuant to Section 9.18(a) and
AT&T has not effectively terminated this Agreement pursuant to Section 9.18(b),
Comcast shall have the right to delay the consummation of the Mergers and the
other transactions contemplated by this Agreement until the date that is one
hundred eighty (180) calendar days after the QUIPS Failure Date. At any time
prior to the expiration of the 180 calendar day period referred to in the
preceding sentence, Comcast may elect to consummate the Mergers and the other
transactions contemplated by this Agreement on ten (10) Business Days' written
notice to AT&T in which event the Closing Date shall occur on the date
specified by Comcast in its notice or, if on such date all conditions to the
Mergers set forth in Article 10, other than conditions that by their nature are
to be satisfied at the Effective Time, are not satisfied or (to the extent
permissible) waived, on the earliest date after such date on which all such
conditions are satisfied or (to the extent permissible) waived; provided that
if Comcast delivers a notice pursuant to this Section 9.18(c) prior to the
second Business Day occurring after the forty-Fifth calendar day after the
QUIPS Failure Date, Comcast must specify a date in its notice that is no later
than the sixtieth day after the QUIPS Failure Date. Notwithstanding the
foregoing, the Closing Date shall occur no later than the date that is one
hundred eighty (180) calendar days after the QUIPS Failure Date or, if on such
date all conditions to the Mergers set forth in Article 10, other than
conditions that by their nature are to be satisfied at the Effective Time, are
not satisfied or (to the extent permissible) waived, on the earliest date after
such date on which all such conditions are satisfied or (to the extent
permissible) waived.

     (d) If at any time during the 180 calendar day period specified above, it
appears reasonably unlikely that the QUIPS Exchange shall occur, AT&T and
Comcast will use their commercially reasonable efforts to obtain, on terms
reasonably acceptable to Comcast and AT&T, the consent of Microsoft to the
QUIPS Transfer. If Microsoft consents to the QUIPS Transfer in accordance with
the preceding sentence and on any Closing Date specified or determined pursuant
to Section 9.18(c) the QUIPS Exchange does not occur, the QUIPS Transfer shall
be effected on such Closing Date.

     (e) On any Closing Date specified or determined pursuant to Section
9.18(c), if neither the QUIPS Exchange nor the QUIPS Transfer occurs, AT&T
Broadband will, immediately prior to the Separation on such Closing Date, pay
to AT&T an amount equal to the QUIPS Fair Market Value as determined as set
forth below in Section 9.18(f), which payment shall be made to give effect to
the


                                     A-109



retention of the QUIPS by AT&T and in connection with the transfer of assets
and liabilities to AT&T Broadband as contemplated herein.

     (f) Within 10 (ten) Business Days after the QUIPS Failure Date, each of
AT&T and Comcast shall deliver to the other an appraisal conducted by an
investment banking firm of nationally recognized standing of the fair market
value of the QUIPS at such time. If the higher of the two appraisals is not
greater than 110% of the lower of the two appraisals, then the average of the
two appraisals shall be deemed to be the fair market value of the QUIPS. If the
higher of the two appraisals is greater than 110% of the lower of the two
appraisals, then the two investment banking firms shall promptly select a third
investment banking Firm of nationally recognized standing acceptable to Comcast
and AT&T and shall cause such Firm to deliver within ten (10) Business Days of
the delivery of the initial appraisals an appraisal of the fair market value of
the QUIPS. In the event such third appraisal is required pursuant to the
immediately preceding sentence, the fair market value of the QUIPS as
determined by such third appraisal shall be averaged with the initial appraisal
that was closer in value to such third appraisal and such average shall be
deemed to be the fair market value of the QUIPS. The fair market value of the
QUIPS as determined pursuant to this Section 9.18(f) is referred to herein as
the "QUIPS Fair Market Value" and shall be determined without regard to accrued
and unpaid interest on the QUIPS.

     (g) Notwithstanding any other provision of this Agreement, if the Closing
Date is delayed pursuant to this Section 9.18, the End Date shall be extended
for the aggregate period of the delay; provided that the End Date shall in no
event be extended pursuant to this Section 9.18(g) for a period exceeding one
hundred eighty-five (185) calendar days after the QUIPS Failure Date.

     (h) In the event that the QUIPS Exchange and the QUIPS Transfer do not
occur, AT&T Broadband shall have no liability in respect of the QUIPS other
than as provided in Section 5.03(e) of the Separation and Distribution
Agreement and subject to Section 9.18(e). In the event that the QUIPS Exchange
does occur, none of AT&T Broadband and its Affiliates shall have any further
liability in respect of the QUIPS notwithstanding anything to the contrary
contained herein or in any other Transaction Agreement; provided that this
sentence shall not apply if the QUIPS Exchange is unwound pursuant to Section
3.03 of the Exchange Agreement. If the QUIPS Exchange has been completed and
not unwound AT&T will cancel the QUIPS immediately after the Effective Time.

     (i) AT&T and Comcast acknowledge and agree that in the event of an
Exchange Closing (as defined in the Exchange Agreement), notwithstanding
anything to the contrary in the Indenture or in the Trust Agreement, interest
in respect of the Debentures and Distributions (as defined in the Exchange


                                     A-110



Agreement) in respect of the QUIPS shall accrue up to and including the day
immediately prior to, and shall be payable on, the date of the Exchange
Closing.

     (j) For purposes of this Section 9.18, "QUIPS Transfer" means the
following actions: (i) the execution by AT&T Broadband of documents and
agreements identical in form, substance and economic effect to the holder of
QUIPS to the existing QUIPS transaction documents (including, but not limited
to, the Trust Agreement, the Trust Common Securities, the Indenture, the
Debentures, the Guarantee Agreement, the Expense Agreement and the Registration
Rights Agreement and any documents or agreements executed in connection
therewith or delivered pursuant thereto, but excluding any such documents or
provisions of such documents relating to the warrants issued to Microsoft in
connection with the sale of the QUIPS or relating to commercial transactions
entered into in connection with the issuance of the QUIPS), except such
differences as are required to reflect the identity of AT&T Broadband (rather
than AT&T) as party to each thereof and except that Article 12 of Indenture
will provide that, prior to the Mergers, the Debentures will be convertible
into AT&T Broadband Common Stock and following the Mergers, the Debentures will
be convertible into shares of Parent Common Stock, in each case, at a
conversion price appropriately adjusted for the Distribution and the Mergers,
(ii) the delivery by AT&T Broadband of all such replacement QUIPS transaction
documents other than the replacement Trust Common Securities to AT&T or its
designee and retention by AT&T Broadband of the replacement Trust Common
Securities, (iii) the delivery by AT&T or AT&T's designee of all such
replacement QUIPS transaction documents received from AT&T Broadband to
Microsoft in exchange for transfer by Microsoft to AT&T of the existing QUIPS
transaction documents and the release of AT&T and its subsidiaries in full from
any obligations under any of such agreements and the termination of all rights
of Microsoft thereunder other than the documents and rights relating to the
warrants issued to Microsoft by AT&T in connection with the sale of the QUIPS
and (iv) the termination of any further liability of the AT&T Broadband Group
in respect of the QUIPS; all of the foregoing to be on terms reasonably
satisfactory to AT&T and AT&T Broadband.

     SECTION 9.19. Index Stock. Each of Parent, Comcast and AT&T agrees to use
its reasonable best efforts to cause (i) if the Preferred Structure Approval is
obtained, the Parent Class A Common Stock to be included in the Index at the
Effective Time or as promptly thereafter as possible or (ii) if the Preferred
Structure Approval is not obtained, the Parent Class C Common Stock to be
included in the Index at the Effective Time or as promptly thereafter as
possible.

     SECTION 9.20. Use of Name and Logo. (a) Effective as of the Effective
Time, for a period of 180 calendar days after the Closing Date, AT&T (on behalf
of itself and its Subsidiaries) hereby grants each of Parent and its
Subsidiaries a


                                     A-111



limited, non-exclusive, non-transferable, royalty-free license to use the
trademarks, trade names, service marks, service names, logos and other indicia
of origin of AT&T or any of its Subsidiaries (the "AT&T Marks") to the same
extent, and in the same manner as, used at the Effective Time; provided that
each of Parent and its Subsidiaries will exercise commercially reasonable
efforts to remove all AT&T Marks from the AT&T Broadband Assets as soon as
reasonably practicable, and in any event within 180 calendar days, following
the Closing Date. After 180 calendar days following the Closing Date, Parent
and its Subsidiaries shall have no further rights or licenses to use any of the
AT&T Marks in connection with any products or services.

     (b) During the 180 calendar day period provided above, Parent and its
Subsidiaries shall ensure that any products or services being provided in
connection with the AT&T Marks are provided in accordance with standards of
quality equal to or greater than the standards of quality relating to products
and services which AT&T and its Subsidiaries provided under the AT&T Marks
immediately prior to the Effective Time. AT&T may conduct during regular
business hours and with ten (10) calendar days prior notice an examination of
products and services being provided by Parent or its Subsidiaries under the
AT&T Marks at Parent's facilities to determine compliance of such products and
services with the applicable standards of quality. If such products and
services shall, in the reasonable opinion of AT&T, fail to conform with such
standards of quality AT&T shall so notify Parent. Upon such notification Parent
and its Subsidiaries shall have a reasonable time within which to conform with
the standards of quality.

     (c) Notwithstanding the foregoing, nothing in this Section 9.20 will
require any of Parent and its Subsidiaries to remove or discontinue using any
such name or mark that is affixed to converters or other items already
installed in or to be used in customer homes or properties and neither Parent
nor any of its Subsidiaries will have any liability in respect thereof;
provided that at the First time Parent or its Subsidiaries shall have access to
such converters or other items (e.g., for repair or replacement), Parent or its
Subsidiaries shall completely obliterate or affix a label that completely
obscures any AT&T Mark on such converters or other items.

     SECTION 9.21. Exchange Agreement. Concurrently with the execution of this
Agreement, AT&T and Parent are executing the Admission Agreement pursuant to
which AT&T and Parent are (i) agreeing to effect the Exchange and, if
necessary, the unwind of the QUIPS Exchange, as provided in the Exchange
Agreement, (ii) becoming parties to the Exchange Agreement and (iii) making the
representations and warranties referred to in Sections 9.01(b) and 9.01(c),
respectively, thereof. AT&T will provide information to Comcast in order to


                                     A-112



permit Comcast to satisfy its obligations under Section 6.06(b) of the Exchange
Agreement, subject to applicable pre-existing third party confidentiality
restrictions and subject to applicable law. AT&T and Parent agree that
Microsoft will be a third party beneficiary of the First sentence of this
Section 9.21.

     SECTION 9.22. Significant Excepted Transactions. (a) AT&T may enter into
an agreement relating to a Significant Excepted Transaction but only if such
agreement would not reasonably be expected to result in a delay in the
consummation of the transactions contemplated by this Agreement past the End
Date; provided that, in such event, at the request of Comcast, the End Date
shall be extended by the reasonably expected period of delay in the
consummation of the transactions contemplated by this Agreement caused by such
Significant Excepted Transaction up to 60 days.

     (b) If AT&T proposes to enter into an agreement relating to a Significant
Excepted Transaction that would reasonably be expected to result in a delay in
the consummation of the transactions contemplated by this Agreement past the
End Date but which would not reasonably be expected to result in a delay in the
consummation of the transactions contemplated by this Agreement to a date that
is more than sixty (60) calendar days after the End Date, then at the request
of AT&T, AT&T and Comcast will use commercially reasonable efforts to obtain
the consent of Microsoft to extend the date specified in Section 10.01(c) of
the Exchange Agreement to the date after the End Date (which date shall be no
later than sixty (60) calendar days after the End Date) on which it is
reasonably anticipated that the transactions contemplated by this Agreement may
be consummated if AT&T were to enter into the proposed agreement relating to
the Significant Excepted Transaction. If Microsoft does not agree to so extend
the date specified in Section 10.01(c) of the Exchange Agreement, AT&T may not
enter into the proposed agreement relating to the Significant Excepted
Transaction. If Microsoft does agree to so extend such date, AT&T may enter
into the proposed agreement relating to the Significant Excepted Transaction;
provided that AT&T agrees to pay and be responsible for any costs, expenses or
fees payable in connection with obtaining the consent of Microsoft to so extend
such date and to indemnify AT&T Broadband from any such costs, expenses or
fees. In the event AT&T enters into the agreement relating to the Significant
Excepted Transaction, the End Date shall be extended to the same date that
Microsoft has agreed to extend the date specified in Section 10.01(c) of the
Exchange Agreement but in no event more than 60 days after the prior End Date.

     (c) AT&T may not enter into any agreement relating to a Significant
Excepted Transaction that would reasonably be expected to result in a delay in
the consummation of the transactions contemplated by this Agreement to a date
that is more than sixty (60) calendar days after the End Date.


                                     A-113



     (d) For purposes of this Section 9.22, the reasonably expected delay in
the consummation of the transactions contemplated by this Agreement that would
result from a Significant Excepted Transaction shall be determined as of the
date that AT&T would propose to enter into an agreement relating to a
Significant Excepted Transaction.

     SECTION 9.23. Comcast's AT&T Stock. (a) (i) Prior to the Record Date, AT&T
shall designate a series of preferred shares, par value $1.00 per share, of
AT&T as the "Series K Convertible Preferred Stock" (the "AT&T Convertible
Preferred Stock"). The AT&T Convertible Preferred Stock issued in accordance
with Section 9.23(a)(ii) shall in the aggregate be mandatorily convertible on
the twenty-third (23rd) Combined Trading Day following the Closing Date (the
"Conversion Date") into a number of shares of AT&T Common Stock equal to the
Conversion Amount (as adjusted to account for any stock split, dividend,
reclassification, recapitalization, stock combination or similar event the
record date for which is after the Record Date and on or before the Conversion
Date; provided that, in the event AT&T declares a stock dividend the record
date for which is the Record Date (other than the Distribution), then (x) in
lieu of shares of AT&T Common Stock the AT&T Convertible Preferred Stock shall
instead be convertible into a combination of AT&T Common Stock and, for each
such share of AT&T Common Stock, such shares of stock as are distributed upon
each share of AT&T Common Stock in such stock dividend (the "Dividend Stock")
and (y) the number of shares of AT&T Common Stock and Dividend Stock for which
the shares of AT&T Convertible Preferred Stock shall be convertible shall be
determined according to a formula based upon the formula provided in the
definition of "Conversion Amount," appropriately adjusted to account for such
stock dividend by including the Trading Value or NYSE Trading Value, as the
case may be, of such Dividend Stock in such formula), it being understood that
the 10% limitation set forth in the definition of Conversion Amount shall apply
to each class of stock to be issued upon conversion. Subject to the foregoing,
the AT&T Convertible Preferred Stock shall have such rights, preferences and
limitations as AT&T and Comcast shall mutually agree prior to the date that is
two Business Days prior to the Record Date.

          (ii) Immediately prior to the Record Date, Comcast shall exchange or
     cause to be exchanged each share of AT&T Common Stock held by Comcast or
     by any Comcast Subsidiary for one one-thousandth of a share of AT&T
     Convertible Preferred Stock and AT&T and Comcast shall make customary
     representations and warranties in connection therewith.


                                     A-114



     (b) If immediately after giving effect to the mandatory conversion on the
Conversion Date pursuant to Section 9.23(a)(i), Comcast and the Comcast
Subsidiaries own more than 5% of the outstanding shares of AT&T Common Stock,
Comcast agrees that it will sell or cause to be sold such excess shares within
one year after the Conversion Date. Prior to the time that such excess shares
are sold, Comcast agrees that it will vote or cause to be voted such excess
shares on all matters submitted to shareholders of AT&T in the same proportion
as all other holders of such stock vote on such matter. In the event that, as
of the Conversion Date, all of the excess shares could not be sold under Rule
144 under the 1933 Act within three months of the Conversion Date, AT&T shall
provide customary registration rights in respect of such excess shares. The
provisions of this Section 9.23(b) shall also apply to any Dividend Stock.

     (c) AT&T shall not effect any stock dividend the record date for which is
between the date following the Record Date and the Conversion Date, inclusive.

     (d) The shares of AT&T Common Stock (and Dividend Stock, if any) issued
upon conversion of the AT&T Convertible Preferred Stock shall be considered
Registrable Securities (as defined in the AT&T Registration Rights Agreement),
but subject to the last sentence of such definition.


                                   ARTICLE 10

     (g) all License Consents, Franchise Consents, PUC Consents and other

as would not, individually or in the aggregate, reasonably be expected to have
a Comcast Material Adverse Effect or an AT&T Broadband Material Adverse Effect;

     (h) no court, arbitrator or other Governmental Authority shall have issued

     (j) AT&T shall have obtained a supplemental private letter ruling or

will not cause the Separation and Distribution to fail to be qualified as a
tax-free transaction pursuant to Section 355 of the Code and (z) the Separation

Code. In lieu of obtaining the supplemental private letter ruling from the IRS

agree to obtain an opinion to the same effect from tax counsel of a nationally
recognized reputation mutually acceptable to AT&T and Comcast in form and
substance reasonably satisfactory to AT&T and Comcast, on the basis of certain

December 19, 2001, shall equal or exceed 66 2/3% of the aggregate principal
amount of indebtedness outstanding under the Notes Indenture on December 19,
2001 and (ii) AT&T shall not have issued after the date of this Agreement any

the following further conditions:

     (a) (i) Comcast shall have performed in all material respects all of its
obligations hereunder required to be performed by it at or prior to the

     SECTION 11.02. Effect of Termination. If this Agreement is terminated
pursuant to Section 11.01, this Agreement shall become void and of no effect
without liability of any party hereto (or any shareholder, director, officer,
employee, agent, consultant or representative of such party) to the other
parties hereto, except that (a) the agreements contained in this Section 11.02,
in the Confidentiality Agreements (subject to the terms thereof), and in
Section 11.03 shall survive the termination hereof and (b) no such termination
shall relieve any party hereto of any liability or damages resulting from any
intentional breach by such party of a covenant or other agreement included in
this Agreement or any knowing breach of a representation or warranty included
in this Agreement.

     SECTION 11.03. Fees and Expenses. (a) Except as otherwise provided in this
Section 11.03, all costs and expenses incurred in connection with this
Agreement and the other Transaction Agreements shall be paid by the party
incurring such cost or expense whether or not the Mergers are consummated.
Notwithstanding the foregoing, (i) AT&T shall pay any costs and expenses
incurred by AT&T Broadband or any AT&T Broadband Subsidiary in connection with
this Agreement and the other Transaction Agreements that are in excess of $120
million (exclusive of any costs and expenses incurred by AT&T Broadband or any
AT&T Broadband Subsidiary as described in clauses (ii), (iii), (iv) and (v) of
this sentence), (ii) AT&T Broadband shall pay any costs and expenses incurred
in connection with any Financing arrangements entered into by AT&T Broadband


                                     A-121



as contemplated by Section 9.15 (other than any costs and expenses incurred in
connection with the Financing arrangements entered into by AT&T Broadband and
Parent on April 26, 2002 or May 3, 2002, which shall be paid by Comcast), (iii)
AT&T Broadband shall pay any costs and expenses (to the extent not paid by
Parent) incurred in connection with the actions contemplated by Section 9.16,
(iv) AT&T Broadband shall pay 50% of any costs and expenses incurred by AT&T or
any of its Subsidiaries in connection with obtaining the Note Consents (through
either a one-time cash payment of a consent fee or through a coupon increase or
a combination thereof) that are in excess of $50 million, subject to and as
determined in accordance with Sections 11.03(b) and 11.03(c), and (v) AT&T
(other than any AT&T Broadband Entity) and Comcast each shall pay 50% of any
fees and expenses, other than attorneys' and accounting fees and expenses,
incurred in relation to the printing, Filing and mailing of the Registration
Statement and the Joint Proxy Statement.

     (b) The costs of obtaining the Note Consents shall include (i) any
transaction costs paid in obtaining the Note Consents (including, without
limitation, the costs, expenses and commissions of any solicitation agent,
counsel, Financial advisors and underwriters, any printing and mailing costs,
any SEC Filing fees, rating agency fees and any costs of the trustee under the
Notes Indenture for which AT&T or any Affiliate thereof is responsible) plus
(ii) (A) the amount of any one-time cash payment made to obtain a Note Consent,
and (B) with respect to an increase in the coupon on any of the series of
securities issued under the Notes Indenture in connection with obtaining a Note
Consent, the amount equal to the excess of the present value of the increased
coupon on such series of securities over the present value of the coupon on
such series of securities immediately prior to the increase of the coupon, in
each case calculated based on "market convention" (e.g., calculated on a 30/360
day basis in the case of a domestic fixed rate note and on an actual/360 day
basis in the case of a floating rate note, etc.) using a discount rate equal to
the Market Rate (determined as specified below in Section 11.03(c)). The
amounts described in clauses (i) and (ii) of the immediately preceding sentence
shall be reduced by the amount of any present or future tax benefit to AT&T as
a result of making any payments of such amounts. Such tax benefit shall be
calculated by multiplying the payment giving rise to the tax benefit by the
highest combined federal, state and local marginal corporate tax rate in effect
as of the Effective Time and, in the case of any future tax benefit, by
discounting such future tax benefit at the Market Rate.

     (c) The Market Rate shall be determined by mutual agreement of AT&T and
Comcast. In the event AT&T and Comcast cannot reach agreement within five (5)
calendar days of the date of determination (as set forth below), the Market
Rate shall be determined by a process in which AT&T and Comcast will mutually
appoint four broker/dealer Firms of national reputation to determine the


                                     A-122



then-current market yield for each impacted series of securities. After each
Firm has determined the then-current market yield for each impacted series of
securities, the arithmetic average of the four rates will be the Market Rate.
In determining each such Market Rate, the impacted series of securities shall
be deemed to be securities of AT&T, after giving effect to the Separation,
Distribution and the Mergers. Any determination of Market Rate pursuant to this
Section 11.03(c) shall be Final and binding. Each of AT&T and Comcast shall
bear the fees and expenses of the broker/dealer Firms which it appoints in
making such determinations. The Market Rate shall be determined in the case of
clause (ii)(B) of Section 11.03(b) as of the settlement date of the
transaction.

     (d) If this Agreement is terminated pursuant to Section 11.01(b)(iii) or
11.01(c)(i), Comcast shall pay to AT&T a termination fee of $1.5 billion in
cash (without duplication) (the "Comcast Termination Fee").

     (e) If this Agreement is terminated pursuant to Section 11.01(d)(i) or
11.01(d)(ii), AT&T shall pay to Comcast (or a wholly owned subsidiary of
Comcast designated by Comcast) a termination fee of $1.5 billion in cash
(without duplication) (the "AT&T Termination Fee").

     (f) If (i) this Agreement is terminated pursuant to Section 11.01(b)(iv),
(ii) after the date hereof and prior to the AT&T Shareholders' Meeting, an AT&T
Broadband Acquisition Proposal is made or continued or renewed by any Person
and not withdrawn prior to the AT&T Shareholders' Meeting and (iii) within one
year of the AT&T Shareholders' Meeting, either (A) AT&T or any AT&T Subsidiary
enters into an agreement with any Person with respect to an AT&T Broadband
Acquisition Proposal, that provides for (I) transfer or issuance of securities
representing more than 50% of the equity or voting interests in AT&T or the
AT&T Broadband Group or 75% of the equity or voting interests in any AT&T
Significant Broadband Subsidiary, (II) a merger, consolidation,
recapitalization or another transaction resulting in the issuance of cash or
securities of any Person (other than a reincorporation or a holding company
merger that results in the AT&T shareholders owning all of the equity interests
in the surviving corporation) to AT&T shareholders in exchange for more than
50% of the equity or voting interests in AT&T or the AT&T Broadband Group or
75% of the equity or voting interests in any AT&T Significant Broadband
Subsidiary or (III) transfer of assets, securities or ownership interests
representing more than 50% of the consolidated assets or EBITDA generating
power of AT&T or the AT&T Broadband Group or 75% of the consolidated assets or
EBITDA generating power of any AT&T Significant Broadband Subsidiary or (B) any
Person commences a tender offer that results in the acquisition by the Person
making the tender offer of a majority of the AT&T Common Stock, then AT&T


                                     A-123



shall pay to Comcast (or a wholly owned subsidiary of Comcast designated by
Comcast) the AT&T Termination Fee.

     (g) Any payment of the Comcast Termination Fee or AT&T Termination Fee
pursuant to this Section 11.03 shall be made within one Business Day after
termination of this Agreement, except that any payment of the AT&T Termination
Fee pursuant to Section 11.03(f) shall be paid within one Business Day after it
becomes payable. Any payment of the Comcast Termination Fee or AT&T Termination
Fee shall be made by wire transfer of immediately available funds. If any party
hereto fails to pay to the other parties promptly any fee or expense due
hereunder (including the Comcast Termination Fee or AT&T Termination Fee), the
defaulting party shall pay the costs and expenses (including legal fees and
expenses) in connection with any action, including the prosecution of any
lawsuit or other legal action, taken to collect payment, together with interest
on the amount of any unpaid fee at the publicly announced prime rate of The
Bank of New York in New York City from the date such fee was required to be
paid to the date it is paid.

     (h) Notwithstanding any other provision of this Agreement, any payment by
AT&T of the AT&T Termination Fee or any payment by Comcast of the Comcast
Termination Fee, in each case pursuant to Section 11.03, shall relieve (i) AT&T
and AT&T Broadband or (ii) Comcast, as the case may be, from any further
liability or damages under any provision of this Agreement (other than Section
11.03(a)) or in connection with this Agreement and the transactions
contemplated hereby.

"Corporation").

     SECOND: The location and post office address of the Corporation's current
registered office in this Commonwealth is:

        1500 Market Street, 35th floor
        Philadelphia, PA 19102-2148

     THIRD: The Corporation is incorporated under the provisions of the Business
Corporation Law of 1988. The purpose or purposes for which the Corporation is
organized are:

     To have unlimited power to engage in and to do any lawful act concerning
any or all lawful business for which corporations may be incorporated under the
Business Corporation Law.

     FOURTH: The term of its existence is perpetual.

     FIFTH: A. The aggregate number of shares which the Corporation shall have
authority to issue is SEVEN BILLION FIVE HUNDRED MILLION (7,500,000,000) shares
of Class A Common Stock, par value $0.01 per share, SEVEN BILLION FIVE HUNDRED
MILLION (7,500,000,000) shares of Class A Special Common Stock, par value $0.01
per share, SEVENTY FIVE MILLION (75,000,000) shares of Class B Common Stock, par
value $0.01 per share, and TWENTY MILLION (20,000,000) shares of Preferred
Stock, which the Board of Directors may issue, in one or more series, without
par value, with full, limited, multiple, fractional, or no voting rights, and
with such designations, preferences, qualifications, privileges, limitations,
restrictions, options, conversion rights and other special or relative rights as
shall be fixed by the Board of Directors.

    B. The descriptions, preferences, qualifications, limitations, restrictions
and the voting, special or relative rights in respect of the shares of each
class of Common Stock are as follows:

        1. (a) Subject to paragraph (B)(1)(c) of this Article FIFTH, each share
    of Class A Common Stock shall entitle the holder thereof to the number of
    votes equal to a quotient the numerator of which is the excess of (i) the
    Total Number of Votes (as defined below) over (ii) the sum of (A) the Total
    Number of B Votes (as defined below) and (B) the Total Number of Other Votes
    (as defined below) and the denominator of which is the number of outstanding
    shares of Class A Common Stock (provided that if at any time there are no
    outstanding shares of Class B Common Stock, each share of Class A Common
    Stock shall entitle the holder thereof to one (1) vote) and each share of
    Class B Common Stock shall entitle the holder thereof to fifteen (15) votes.
    Holders of shares of Class A Special Common Stock shall not be entitled to
    vote for the election of Directors (as defined below in Article SIXTH) or
    any other matter except as may be required by applicable law, in which case
    each share of Class A Special Common Stock shall entitle the holder thereof
    to the same number of votes to which each holder of Class A Common Stock is
    entitled for each of such holder's shares of Class A Common Stock. "Total
    Number of Votes" on any record date is equal to a quotient the numerator of
    which is the Total Number of B Votes on such record date and the denominator
    of which is the B Voting Percentage (as defined below) on such record date.
    "Total Number of B Votes" on any record date is equal to the product of (i)
    15 and (ii) the number of outstanding shares of Class B Common Stock on such
    record date. "Total Number of Other Votes" on any record date means the
    aggregate number of votes to which holders of all classes of capital stock
    of the Corporation other than holders of Class A Common Stock and Class B
    Common Stock are entitled to cast on such record date in an election of
    Directors. "B Voting Percentage" on any record date means the portion
    (expressed as a percentage) of the total number of votes entitled to be cast
    in an election of Directors by the holders of capital stock of the
    Corporation to which all holders of Class B Common Stock are entitled to
    cast on such record date in an election of Directors, as specified and
    determined pursuant to paragraph (B)(1)(c) of this Article FIFTH.

        (b) Except as provided in Article SEVENTH or required by applicable law,
    only the holders of Class A Common Stock, the holders of Class B Common
    Stock and the holders of any other class or series of Common Stock,
    Preferred Stock or other class of capital stock of the Corporation (if any)
    with voting rights shall be entitled to vote and shall vote as a single
    class on all matters with respect to which a vote of the shareholders of the
    Corporation is required or permitted under applicable law, these Articles of
    Incorporation, or the By-Laws of the Corporation. Whenever applicable law,
    these Articles of Incorporation or the By-Laws of the





    Corporation provide for a vote of the shareholders of the Corporation on any
    matter, approval of such matter shall require the affirmative vote of a
    majority of the votes cast by the holders entitled to vote thereon unless
    otherwise expressly provided under applicable law, these Articles of
    Incorporation or the By-Laws of the Corporation.

        (c) Notwithstanding any other provision of these Articles of
    Incorporation, including paragraph (B)(1)(a) of this Article FIFTH, but
    subject to Article SEVENTH, with respect to any matter on which the holders
    of Class B Common Stock and the holders of one or more classes or series of
    Common Stock, Preferred Stock or any other class of capital stock of the
    Corporation (if any) vote as a single class, each share of Class B Common
    Stock shall entitle the holder thereof to the number of votes necessary so
    that, if all holders of Class B Common Stock and all holders of each such
    other class or series of Common Stock, Preferred Stock and other class of
    capital stock of the Corporation (if any) were to cast all votes they are
    entitled to cast on such matter, the holders of the Class B Common Stock in
    the aggregate would cast thirty three and one-third (33 1/3) per cent of the
    total votes cast by all such holders, subject to reduction as set forth in
    the following sentence. If at any time after the Effective Time for any
    reason whatsoever the number of shares of Class B Common Stock outstanding
    at such time is reduced below the number of shares of Class B Common Stock
    outstanding at the Effective Time (appropriately adjusted for any stock
    dividend paid in Class B Common Stock, stock splits or reverse stock splits
    of the Class B Common Stock or combinations, consolidations or
    reclassifications of the Class B Common Stock), the percentage specified in
    the preceding sentence shall be reduced to a percentage equal to the product
    of (i) thirty three and one-third (33 1/3) and (ii) the fraction obtained by
    dividing the number of shares of Class B Common Stock outstanding at such
    time by the number of shares of Class B Common Stock outstanding at the
    Effective Time (appropriately adjusted for any stock dividend paid in Class
    B Common Stock, stock splits or reverse stock splits of the Class B Common
    Stock or combinations, consolidations or reclassifications of the Class B
    Common Stock). No reduction in the percentage of the voting power of the
    Class B Common Stock pursuant to the preceding sentence shall be reversed by
    any issuance of Class B Common Stock that occurs after such reduction.

        2. The holders of Class A Common Stock, the holders of Class A Special
    Common Stock and the holders of Class B Common Stock shall be entitled to
    receive, from time to time, when and as declared, in the discretion of the
    Board of Directors, such cash dividends as the Board of Directors may from
    time to time determine, out of such funds as are legally available therefor,
    in proportion to the number of shares held by them, respectively, without
    regard to class.

        3. The holders of Class A Common Stock, the holders of Class A Special
    Common Stock, and the holders of Class B Common Stock shall be entitled to
    receive, from time to time, when and as declared by the Board of Directors,
    such dividends of stock of the Corporation or other property as the Board of
    Directors may determine, out of such funds as are legally available
    therefor. Stock dividends on, or stock splits of, any class of Common Stock
    shall not be paid or issued unless paid or issued on all classes of Common
    Stock, in which case they shall be paid or issued only in shares of that
    class; provided, however, that stock dividends on, or stock splits of, Class
    B Common Stock may be paid or issued in shares of Class A Special Common
    Stock. Any decrease in the number of shares of any class of Common Stock
    resulting from a combination or consolidation of shares or other capital
    reclassification shall not be permitted unless parallel action is taken with
    respect to each other class of Common Stock, so that the number of shares of
    each class of Common Stock outstanding shall be decreased proportionately.
    Notwithstanding anything to the contrary contained herein, in the event of a
    distribution of property, plan of merger or consolidation, plan of asset
    transfer, plan of division, plan of exchange, or recapitalization pursuant
    to which the holders of Class A Common Stock, the holders of Class A Special
    Common Stock and the holders of Class B Common Stock would be entitled to
    receive equity interests of one or more corporations (including, without
    limitation, the Corporation) or other entities, or rights to acquire such
    equity interests, then the Board of Directors may, by resolution duly
    adopted, provide that the holders of Class A Common Stock, the holders of
    Class A Special Common Stock, and the holders of Class B Common Stock,
    respectively and as separate classes, shall receive with respect to their
    Class A Common Stock, Class A Special Common Stock, or Class B Common Stock
    (whether by distribution, exchange, redemption or otherwise), in proportion
    to the number of shares held by them, equity interests (or rights to acquire
    such equity interests) of separate classes or series having substantially
    equivalent relative designations, preferences, qualifications, privileges,
    limitations, restrictions and rights as the relative designations,
    preferences, qualifications, privileges, limitations, restrictions and
    rights of the Class A Common Stock, Class A Special Common Stock and Class B
    Common Stock. Except as provided above, if there should be any distribution
    of property, merger, consolidation, purchase or acquisition of property or
    stock, asset transfer, division, share exchange, recapitalization or
    reorganization of the Corporation, the holders of Class A Common Stock, the
    holders of Class A Special Common Stock, and the holders of Class B Common
    Stock shall receive the shares of stock, other securities or rights or other
    assets as would be issuable or payable upon such distribution, merger,
    consolidation, purchase or acquisition of such property or stock, asset
    transfer, division, share exchange, recapitalization or reorganization in
    proportion to the number of shares held by them, respectively, without
    regard to class.


                                       2




        4. Each share of Class B Common Stock shall be convertible at the option
    of the holder thereof into one share of Class A Common Stock or one share of
    Class A Special Common Stock. Each share of Class B Common Stock shall be
    cancelled after it has been converted as provided herein.

        5. Subject to Article SEVENTH and except as otherwise permitted by
    applicable law, each and any provision of these Articles of Incorporation
    may from time to time, when and as desired, be amended by a resolution of
    the Board of Directors and the affirmative vote of a majority of the votes
    cast by all shareholders entitled to vote thereon, as determined in
    accordance with the provisions of this Article FIFTH. There shall be no
    class voting on any such amendments or on any other matter except as shall
    be required by Article SEVENTH or by applicable law, in which case there
    shall be required the affirmative vote of a majority of the votes cast by
    the holders of the outstanding shares of each class entitled to vote by
    Article SEVENTH or by applicable law, voting as a separate class.

        6. If there should be any merger, consolidation, purchase or acquisition
    of property or stock, separation, reorganization, division or share
    exchange, the Board of Directors shall take such action as may be necessary
    to enable the holders of the Class B Common Stock to receive upon any
    subsequent conversion of their stock into Class A Common Stock or Class A
    Special Common Stock (as the case may be), in whole or in part, in lieu of
    any shares of Class A Common Stock or Class A Special Common Stock (as the
    case may be) of the Corporation, the shares of stock, securities, or other
    assets as would be issuable or payable upon such merger, consolidation,
    purchase, or acquisition of property or stock, separation, reorganization,
    division or share exchange in respect of or in exchange for such share or
    shares of Class A Common Stock or Class A Special Common Stock (as the case
    may be).

        7. In the event of any liquidation, dissolution or winding up (either
    voluntary or involuntary) of the Corporation, the holders of Class A Common
    Stock, the holders of Class A Special Common Stock and the holders of Class
    B Common Stock shall be entitled to receive the assets and funds of the
    Corporation in proportion to the number of shares held by them,
    respectively, without regard to class.

        8. At all times the Board of Directors shall take such action to adjust
    the conversion privileges of the Class B Common Stock and the number of
    shares of Class B Common Stock to be outstanding after any particular
    transaction to prevent the dilution of the conversion rights of the holders
    of Class B Common Stock.

        9. Except as expressly set forth in these Articles of Incorporation
    (including, without limitation, this Article FIFTH and Article SEVENTH), the
    rights of the holders of Class A Common Stock, the rights of the holders of
    Class A Special Common Stock and the rights of the holders of Class B Common
    Stock shall be in all respects identical.

        10. Neither the holders of the Class A Common Stock nor the holders of
    the Class B Common Stock nor the holders of any other class or series of
    Common Stock, Preferred Stock or other class of capital stock of the
    Corporation, whether issued prior to or after the Effective Time, shall have
    cumulative voting rights.

    meeting of shareholders pursuant to the last sentence of this paragraph
    (B)(5), the second) annual meeting of shareholders of the Corporation after
    the Effective Time shall occur on such date and at such time in April 2004
    as the Board of Directors may determine, or if the Board of Directors fails
    to set a date and time, on the second Thursday of April 2004 at 9:00 o'clock
    a.m., if, in either case, not a holiday on which national banks are or may
    elect to be closed ("Holiday"), and if such day is a Holiday, then such
    meeting shall be held on the next business day at such time. The second (or
    in the event the Board of Directors calls an annual meeting of shareholders
    pursuant to the last sentence of this paragraph (B)(5), the third) annual
    meeting of shareholders of the Corporation after the Effective Time shall
    occur on such date and at such time in April 2005 as the Board of Directors
    may determine, or if the Board of Directors fails to set a date and time, on
    the second Thursday of April 2005 at 9:00 o'clock a.m., if, in either case,
    not a Holiday, and if such day is a Holiday, then such meeting shall be held
    on the next business day at such time. The Corporation may, at the election
    of the Board of Directors, call an annual meeting of shareholders of the
    Corporation in 2003 for the purpose of conducting such business, other than
    the election of Directors, as the Board of Directors shall determine.

       provided that, if the Chairman and the CEO are not the same person, the

       further, that following the initial designation of officers by the CEO

    E. Directors Nominating Committee.

        1. The Directors Nominating Committee (the "Directors Nominating
    Committee") shall have the power to nominate individuals for election by the
    shareholders of the Corporation as Directors at the 2004 annual meeting of
    shareholders of the Corporation and thereafter. During the Initial Term, the
    Directors Nominating Committee shall consist of Mr. Brian L. Roberts, if he
    is the Chairman or the CEO, one (1) Comcast Director who is an Independent
    Person selected by the Comcast Directors and two (2) Directors who are
    Independent Persons selected from the AT&T Directors by the AT&T Directors
    who are Independent Persons and the Independent Directors after consultation
    with Mr. Brian L. Roberts. During the Initial Term, if Mr. Brian L. Roberts
    is not the Chairman or the CEO, the Directors Nominating Committee shall
    consist of two (2) Comcast Directors selected by the Comcast Directors at
    least one of whom shall be an Independent Person and two (2) Directors who
    are Independent Persons selected from the AT&T Directors by the AT&T
    Directors who are Independent Persons and the Independent Directors after
    consultation with a Comcast Director selected by the two (2) Comcast
    Directors selected to serve on the Directors Nominating Committee. During
    the 2004 Term, the Directors Nominating Committee shall consist of Mr. Brian
    L. Roberts, if he is the Chairman or the CEO, one (1) Comcast Director who
    is an Independent Person selected by the Comcast Directors and three (3)
    Directors who are Independent Persons selected from the AT&T Directors and
    the Independent Directors by the Comcast Directors. During the 2004 Term, if
    Mr. Brian L. Roberts is not the Chairman or the CEO, the Directors
    Nominating Committee shall consist of two (2) Comcast Directors selected by
    the Comcast Directors at least one of whom shall be an Independent Person
    and three (3) Independent Persons selected from the AT&T Directors and the
    Independent Directors by the Comcast Directors.


                                       6



    After the 2004 Term, the Directors Nominating Committee shall consist of Mr.
    Brian L. Roberts, if he is the Chairman or CEO, and four (4) Directors who
    are Independent Persons selected by Mr. Brian L. Roberts; provided that no
    more than one (1) person who was a Comcast Director or a Comcast Independent
    Designee may be selected by Mr. Brian L. Roberts as a member of the
    Directors Nominating Committee pursuant to this sentence prior to the
    seventh anniversary of the date that such Director was initially elected to
    the Board of Directors. After the 2004 Term, if Mr. Brian L. Roberts is not
    the Chairman or CEO, the Directors Nominating Committee shall be constituted
    as determined by the Board of Directors. Notwithstanding the foregoing, if
    Mr. Brian L. Roberts is the Chairman or CEO but is ineligible to serve on
    the Directors Nominating Committee at any relevant time under the applicable
    rules of the principal U.S. securities exchange or quotation system on which
    the Class A Common Stock is listed and traded, (i) during the Initial Term
    and the 2004 Term the Directors Nominating Committee shall be composed as it
    would be composed if Mr. Brian L. Roberts were not the Chairman or CEO at
    such time (all of the members of which shall be eligible to serve under such
    rules) and (ii) after the 2004 Term the Directors Nominating Committee shall
    be composed of five (5) directors (all of whom shall be eligible to serve
    under such rules and at least four of whom shall be Independent Persons)
    selected by Mr. Brian L. Roberts; provided that no more than two (2) persons
    who were Comcast Directors or Comcast Independent Designees may be selected
    by Mr. Brian L. Roberts as members of the Directors Nominating Committee
    pursuant to this clause (ii) prior to the seventh anniversary of the date
    such Director was initially elected to the Board of Directors. At any time
    that Mr. Brian L. Roberts is a member of the Directors Nominating Committee,
    he shall be the Chairman of the Directors Nominating Committee. Subject to
    paragraph (E)(2) of this Article SIXTH, all powers otherwise held by the
    Board of Directors to nominate individuals for election by the shareholders
    of the Corporation as Directors shall reside exclusively in the Directors
    Nominating Committee, no such nominations shall be made by the Board of
    Directors and all nominations of the Directors Nominating Committee shall be
    submitted directly to the shareholders of the Corporation without any
    requirement that such nominations be submitted to the Board of Directors for
    its approval or ratification.

        2. If the Directors Nominating Committee is able to reach agreement on a
    full slate of nominations for the 2004 annual meeting of shareholders of the
    Corporation, each of the individuals selected as a nominee who is a Director
    then in office will maintain the status of a "Comcast Director," "AT&T
    Director" or "Independent Director," as the case may be, and each of the
    other individuals, if any, selected as a nominee will have the status
    determined by the Directors Nominating Committee; provided that five (5) of
    the nominees have the status of a "Comcast Director," five (5) of the
    nominees have the status of an "AT&T Director" and two (2) of the nominees
    have the status of an "Independent Director." If the Directors Nominating
    Committee is unable to reach agreement on a full slate of nominations for
    the 2004 annual meeting of shareholders of the Corporation, each of the
    Directors then in office shall be nominated for election as a Director at
    the 2004 annual meeting of shareholders of the Corporation and shall
    maintain the status of a "Comcast Director," "AT&T Director" or "Independent
    Director," as the case may be. In the event that any of such Directors
    declines to stand for election as a Director at the 2004 annual meeting of
    shareholders of the Corporation, a replacement nominee will be selected by
    (i) if the Director declining to stand for election is a Comcast Director, a
    majority of the Comcast Directors then in office (other than the Comcast
    Director declining to stand for election), (ii) if the Director declining to
    stand for election is an AT&T Director, a majority of the AT&T Directors
    then in office (other than the AT&T Director declining to stand for
    election) and (iii) if the Director declining to stand for election is an
    Independent Director, the other Independent Director then in office, subject
    to the prior approval of the Board of Directors (other than the Independent
    Director declining to stand for election); provided that if each of the
    Independent Directors declines to stand for election as a Director at the
    2004 annual meeting of shareholders of the Corporation, replacement nominees
    will be selected by the Board of Directors (other than the Independent
    Directors). If a replacement nominee is selected to replace a declining
    Director pursuant to the preceding sentence, such replacement nominee shall
    be deemed to have the status of the declining Director as a "Comcast
    Director," "AT&T Director" or "Independent Director," as the case may be. If
    a person is elected as a Director at the 2004 annual meeting of shareholders
    who was not nominated pursuant to the provisions of this paragraph (E), such
    person will be deemed to have the status of the former Director he or she
    was elected in lieu of. If multiple persons are elected as Directors at the
    2004 annual meeting of shareholders who were not nominated pursuant to the
    provisions of this paragraph (E) and it is not possible to determine whom
    they were elected in lieu of, their status as "Comcast Directors," "AT&T
    Directors" or "Independent Directors" shall be determined by the entire
    Board of Directors; provided that there shall be five (5) Comcast Directors,
    five (5) AT&T Directors and two (2) Independent Directors and the status of
    the other Directors shall not be affected as a result of such determination.

        3. Any action of the Directors Nominating Committee shall require the
    approval of a majority of the entire Directors Nominating Committee. If any
    provision of this paragraph (E) provides for a selection or determination to
    be made by any given group of Directors, such selection or determination
    shall require the approval of a majority of the Directors in such entire
    group, and (except as otherwise specifically provided) not the approval of
    any given subset of such group.


                                       7




    F. Executive Committee. If the Board of Directors decides to establish an
Executive Committee, if he is willing and able to serve and for so long as he
shall be a member of the Board of Directors, Mr. Ralph J. Roberts shall be the
Chairman of the Executive Committee.

    G. Amendment. Subject to paragraph (H) of this Article SIXTH, until the
earlier to occur of (i) the date on which Mr. Brian L. Roberts is no longer
serving as the Chairman or the CEO and (ii) the sixth anniversary of the
expiration of the Initial Term, the provisions of this Article SIXTH and the
provisions of Article 9 of the By-Laws may not be amended, altered, repealed or
waived in any respect without the prior approval of at least 75% of the entire
Board of Directors.

    H. Termination. If Mr. Brian L. Roberts is no longer serving as the Chairman
or the CEO, the provisions of this Article SIXTH (other than paragraphs (A) and
(E) and the last sentence of paragraph (B)(1), in each case of this Article
SIXTH) shall terminate automatically without any further action of the Board of
Directors or the shareholders of the Corporation; provided that notwithstanding
the foregoing, in the event that Mr. Brian L. Roberts ceases to serve as the
Chairman or the CEO prior to the 2005 annual meeting of shareholders of the
Corporation, the provisions of paragraphs (A), (B), (C), (D)(1)(a)-(c) and (E)
of this Article SIXTH shall survive through the close of such annual meeting.

    SEVENTH: In addition to any other approval required by law or by these
Articles of Incorporation, and notwithstanding any provision of Article FIFTH,
the approval of the holders of Class B Common Stock, voting separately as a
class, shall be necessary to approve (i) any merger or consolidation of the
Corporation with another entity or any other transaction, in each case that
requires the approval of the shareholders of the Corporation pursuant to the law
of the Commonwealth of Pennsylvania or other applicable law, or any other
transaction that would result in any person or group (as such term is defined in
Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) owning
shares representing in excess of 10% of the combined voting power of the
resulting or surviving corporation, or any issuance of securities (other than
pursuant to director or officer stock option or purchase plans) requiring
shareholder approval under the applicable rules and regulations of any stock
exchange or quotation system, (ii) any issuance of shares of Class B Common
Stock or any securities exercisable or exchangeable for or convertible into
shares of Class B Common Stock or (iii) any amendment to these Articles of
Incorporation (including, without limitation, any amendment to elect to have any
of Subchapters E, F, G, H, I and J or Section 2538 of Subchapter D, in each case
of Chapter 25 of the Business Corporation Law of 1988, be applicable to the
Corporation or any amendment to this Article SEVENTH) or the By-Laws of the
Corporation or any other action (including, without limitation, the adoption,
amendment or redemption of a shareholder rights plan) that would, in any such
case, limit the rights of the holders of Class B Common Stock or any subsequent
transferee of Class B Common Stock to transfer, vote or otherwise exercise
rights with respect to capital stock of the Corporation. In addition to any
other approval required by law or by these Articles of Incorporation, and
notwithstanding any provision of Article FIFTH, the approval of the holder of
any class or series of shares of the Corporation shall be necessary to approve
any amendment to these Articles of Incorporation which would make any change in
the preferences, limitations or rights of the shares of such class or series
adverse to such class or series.

    EIGHTH: Special meetings of shareholders may be called only by the Board of
Directors and may not be called by shareholders of the Corporation.

    NINTH: The shareholders of the Corporation shall not be permitted to act by
written consent in lieu of a meeting; provided that notwithstanding the
foregoing, the holders of a majority of the Class B Common Stock shall be
permitted to act by written consent in lieu of a meeting in the exercise of
their approval rights under Article SEVENTH.

    TENTH: The Board of Directors shall have the power to amend the By-Laws to
the extent provided therein, subject only to applicable law. Any amendment to
the By-Laws approved by the shareholders of the Corporation shall not be deemed
to have been adopted by the Corporation unless it has been previously approved
by the Board of Directors.

    ELEVENTH: No person who is or was a Director shall be personally liable, as
such, for monetary damages (other than under criminal statutes and under
federal, state and local laws imposing liability on directors for the payment of
taxes) unless the person's conduct constitutes self-dealing, willful misconduct
or recklessness. No amendment or repeal of this Article ELEVENTH shall apply to
or have any effect on the liability or alleged liability of any person who is or
was a Director for or with respect to any acts or omissions of the Director
occurring prior to the effective date of such amendment or repeal. If the
Business Corporation Law of 1988 is amended to permit a Pennsylvania corporation
to provide greater protection from personal liability for its directors than the
express terms of this Article ELEVENTH, this Article ELEVENTH shall be construed
to provide for such greater protection.

    TWELFTH: No person who is or was an officer of the Corporation shall be
personally liable, as such, for monetary damages (other than under criminal
statutes and under federal, state and local laws imposing liability on directors
for the payment of taxes)


                                       8



unless the person's conduct constitutes self-dealing, willful misconduct or
recklessness. No amendment or repeal of this Article TWELFTH shall apply to or
have any effect on the liability or alleged liability of any person who is or
was an officer of the Corporation for or with respect to any acts or omissions
of the officer occurring prior to the effective date of such amendment or
repeal. If the Business Corporation Law of 1988 is amended to permit a
Pennsylvania corporation to provide greater protection from personal liability
for its officers than the express terms of this Article TWELFTH, this Article
TWELFTH shall be construed to provide for such greater protection.

    THIRTEENTH: Any or all classes and series of shares of the Corporation, or
any part thereof, may be represented by uncertificated shares to the extent
determined by the Board of Directors, except that shares represented by a
certificate that is issued and outstanding shall continue to be represented
thereby until the certificate is surrendered to the Corporation. Within a
reasonable time after the issuance or transfer of uncertificated shares, the
Corporation shall send to the registered owner thereof a written notice
containing the information required to be set forth or stated on certificates.
The rights and obligations of the holders of shares represented by certificates
and the rights and obligations of the holders of uncertificated shares of the
same class and series shall be identical.

    FOURTEENTH: Subchapters E, F, G, H, I and J and Section 2538 of Subchapter
D, in each case of Chapter 25 of the Business Corporation Law of 1988, shall not
be applicable to the Corporation.

    FIFTEENTH:  Henceforth, these Articles supersede the original Articles and
all amendments filed thereto.

     understandings that any of the agreements listed in clause (i) or (ii)
     expressly contemplates will survive the Distribution Date.

     SECTION 2.05. Documents Relating to Transfer of Real Property Interests
and Tangible Property Located Thereon. (a) To the extent necessary, in
furtherance of the assignment, transfer and conveyance of AT&T Communications
Real Property and the assumption of the related AT&T Communications Liabilities
pursuant to Section 2.01(a) and 2.01(b), on or prior to the Distribution Date
each of AT&T and AT&T Broadband, or their applicable Subsidiaries, will execute
and deliver such deeds, lease assignments and assumptions, leases, subleases
and sub-subleases as may be necessary to effect the transactions contemplated
by this Agreement,


                                      22



including this Section 2.05 (collectively, the "Real Property Instruments").
Real Property Instruments will be on mutually acceptable terms.

     (b) Except as otherwise expressly provided in this Agreement or any other
Ancillary Agreement and except for AT&T Broadband Assets, all leasehold
improvements, fixtures, furniture, office equipment, servers, private branch
exchanges, artwork and other tangible property (other than equipment subject to
capital or operating equipment leases, which will be transferred or retained
based on whether the associated capital or operating equipment lease is or is
not an AT&T Broadband Contract or as otherwise provided herein) located as of
the date hereof on any AT&T Communications Real Property shall be transferred
to a member of the AT&T Communications Group.

     (c) Schedule 2.05(c) sets forth a list of AT&T Communications Real
Property currently used in connection with both the AT&T Communications
Business and the AT&T Broadband Business and that following the Distribution
Date will be leased or subleased by members of the AT&T Communications Group to
members of the AT&T Broadband Group, on terms and for the transition period
reflected in Schedule 2.05(c).

     (d) Schedule 2.05(d) sets forth a list of AT&T Broadband Real Property
currently used in connection with both the AT&T Communications Business and the
AT&T Broadband Business and that following the Distribution Date will be leased
or subleased by AT&T Broadband or any of the AT&T Broadband Entities to members
of the AT&T Communications Group, on terms and for the transition period
reflected in Schedule 2.05(d).

     SECTION 2.06. Documents Relating to Other Transfers of Assets and
Assumption of Liabilities. In furtherance of the assignment, transfer and
conveyance of AT&T Broadband Assets and the assumption of AT&T Broadband
Liabilities pursuant to Sections 2.01(a) and 2.01(b), on or prior to the
Distribution Date, (a) AT&T shall execute and deliver, and shall cause its
Subsidiaries to execute and deliver, such bills of sale, stock powers,
certificates of title, assignments of contracts and other instruments of
transfer, conveyance and assignment as and to the extent necessary to evidence
the transfer, conveyance and assignment of all of AT&T's and its Subsidiaries'
right, title and interest in and to the AT&T Broadband Assets to AT&T Broadband
and (b) AT&T Broadband shall execute and deliver, to AT&T and its respective
Subsidiaries such bills of sale, stock powers, certificates of title,
assumptions of contracts and other instruments of assumption, as and to the
extent necessary to evidence the valid and effective assumption by AT&T
Broadband of the AT&T Broadband Liabilities that are not already Liabilities of
an AT&T Broadband Entity; provided that any instruments executed and delivered
pursuant to this Section 2.06 shall be in form and substance reasonably
satisfactory to Comcast.

     SECTION 2.07. Governmental Approvals and Consents. (a) If and to the
extent that the valid, complete and perfected transfer or assignment to AT&T
Broadband of any AT&T Broadband Assets (or from the AT&T Broadband Group of any
AT&T Communications Assets held by any member of such Group) would be a
violation of applicable laws or require any Consent or Governmental Approval in
connection with the Separation or the Distribution, then the transfer or
assignment to or from the AT&T Communications Group, as the case may be, of
such AT&T Broadband Assets or AT&T Communications Assets, respectively, shall
be automatically deemed deferred and any such purported transfer or assignment
shall be null and void until such time as all legal impediments are removed
and/or such Consents or Governmental Approvals have been obtained.
Notwithstanding the foregoing, any such Transferred Asset shall be deemed an
Asset of the transferee AT&T Communications Group or the AT&T Broadband Group,
as applicable, for purposes of determining whether any Liability is a Liability
of the AT&T Communications Group or the AT&T Broadband Group.

     (b) If the transfer or assignment of any Asset intended to be transferred
or assigned hereunder is not consummated prior to or at the Distribution Date,
whether as a result of the provisions of Section 2.07(a) or for any other
reason, then the Person retaining such Asset shall thereafter hold such Asset
for the use and benefit, insofar as reasonably possible, of the Person entitled
thereto (at the expense of the Person entitled thereto). In addition, the
Person retaining such Asset shall take such other actions as may be reasonably
requested by the Person to whom such Asset is to be transferred in order to
place such Person, insofar as reasonably possible, in the same position as if
such Asset had been transferred as contemplated hereby and so that all the
benefits and burdens relating to such AT&T Broadband Asset (or such AT&T
Communications Asset, as the case may be), including possession, use, risk of
loss, potential for gain, and dominion, control and command over such Asset,
are to inure from and after the Distribution Date to the AT&T Broadband Group
(or the AT&T Communications Group, as the case may be). To the extent permitted
by law and to the extent otherwise permissible in light of any required Consent
and/or Governmental Approval, the AT&T Broadband Group shall be entitled to,
and shall be responsible for, the management of any AT&T Broadband Asset not
yet transferred to it as a result of this Section 2.07(b) and the parties agree
to use reasonable commercial efforts to cooperate and coordinate with respect
thereto.

     (c) If and when the Consents and/or Governmental Approvals, the absence of
which caused the deferral of transfer of any Asset


                                      23



pursuant to Section 2.07(a), are obtained, the transfer of the applicable Asset
shall be effected in accordance with the terms of this Agreement and/or the
other applicable Ancillary Agreement.

     (d) The Person retaining an Asset due to the deferral of the transfer of
such Asset shall not be obligated, in connection with the foregoing, to expend
any money unless the necessary funds are advanced by the Person entitled to the
Asset, other than reasonable out-of-pocket expenses, attorneys' fees and
recording or similar fees, all of which shall be promptly reimbursed by the
Person entitled to such Asset.

     SECTION 2.08. Novation of AT&T Broadband Liabilities. (a) Each of AT&T and
AT&T Broadband, at the reasonable written request of the other, shall use its
reasonable commercial efforts to obtain, or to cause to be obtained, any
release, consent, substitution, approval or amendment required to novate and
assign all obligations under agreements, leases, licenses and other obligations
or Liabilities of any nature whatsoever that constitute AT&T Broadband
Liabilities, or to obtain in writing the unconditional release of all parties
to such arrangements other than any member of the AT&T Broadband Group, so
that, in any such case, the members of the AT&T Broadband Group will be solely
responsible for such Liabilities; provided, however, that none of AT&T, AT&T
Broadband or any of their respective Subsidiaries shall be obligated to pay any
consideration or surrender, release or modify any rights or remedies therefor
to any third party from whom such releases, consents, approvals, substitutions
and amendments are requested except as specifically set forth in the Merger
Agreement or elsewhere in this Agreement.

     (b) If AT&T or AT&T Broadband is unable to obtain, or to cause to be
obtained, any such required release, consent, substitution, approval or
amendment, the applicable member of the AT&T Communications Group shall
continue to be bound by such agreements, leases, licenses and other obligations
and, unless not permitted by law or the terms thereof, AT&T Broadband shall, as
agent or subcontractor for such member of the AT&T Communications Group, pay,
perform and discharge fully all the obligations or other Liabilities of such
member of the AT&T Communications Group thereunder from and after the date
hereof. AT&T Broadband shall indemnify each AT&T Indemnitee and hold it
harmless against any Liabilities arising in connection therewith. AT&T shall
cause each member of the AT&T Communications Group, without further
consideration, to pay and remit, or cause to be paid or remitted, to AT&T
Broadband or the applicable member of the AT&T Broadband Group promptly all
money, rights and other consideration received by it or any member of the AT&T
Communications Group in respect of such performance. If and when any such
release, consent, substitution, approval or amendment shall be obtained or such
agreement, lease, license or other rights or obligations shall otherwise become
assignable or able to be novated, AT&T shall promptly assign, or cause to be
assigned, all its rights, obligations and other Liabilities thereunder or any
rights, obligations or other Liabilities of any member of the AT&T
Communications Group to AT&T Broadband or to another member of the AT&T
Broadband Group without payment of further consideration and AT&T Broadband,
without the payment of any further consideration, shall, or shall cause such
other member of the AT&T Broadband Group to, assume such rights and
obligations. Notwithstanding the foregoing, unless AT&T shall so elect, AT&T
Broadband shall assume all Liabilities of any nature whatsoever that would
constitute AT&T Broadband Liabilities as of the Distribution Date, except for
Liabilities of another member of the AT&T Broadband Group.

     SECTION 2.09. Novation of AT&T Communications Liabilities. (a) Each of
AT&T and AT&T Broadband, at the reasonable written request of the other, shall
use its reasonable commercial efforts to obtain, or to cause to be obtained,
any release, consent, substitution, approval or amendment required to novate
and assign all obligations under agreements, leases, licenses and other
obligations or Liabilities of any nature whatsoever that constitute AT&T
Communications Liabilities, or to obtain in writing the unconditional release
of all parties to such arrangements other than any member of the AT&T
Communications Group, so that, in any such case, the members of the AT&T
Communications Group will be solely responsible for such Liabilities; provided,
however, that none of AT&T, AT&T Broadband or any of their respective
Subsidiaries shall be obligated to pay any consideration or surrender, release
or modify any rights or remedies therefor to any third party from whom such
releases, consents, approvals, substitutions and amendments are requested
except as specifically set forth in the Merger Agreement or elsewhere in this
Agreement.

     (b) If AT&T or AT&T Broadband is unable to obtain, or to cause to be
obtained, any such required release, consent, approval, substitution or
amendment, the applicable member of the AT&T Broadband Group shall continue to
be bound by such agreements, leases, licenses and other obligations and, unless
not permitted by law or the terms thereof, AT&T shall, as agent or
subcontractor for such member of the AT&T Broadband Group, pay, perform and
discharge fully all the obligations or other Liabilities of such member of the
AT&T Broadband Group thereunder from and after the date hereof. AT&T shall
indemnify each AT&T Broadband Indemnitee and hold each of them harmless against
any Liabilities arising in connection therewith. AT&T Broadband shall cause
each member of the AT&T Broadband Group, without further consideration, to pay
and remit, or cause to be paid or remitted, to AT&T or the applicable member of
the AT&T Communications Group promptly all money, rights and other
consideration received by it or any member of the AT&T Broadband Group in
respect of such performance. If and when any such release, consent,
substitution approval or amendment shall be obtained or such agreement, lease,
license or other rights or obligations shall otherwise become assignable or


                                      24



able to be novated, AT&T Broadband shall promptly assign, or cause to be
assigned, all its rights, obligations and other Liabilities thereunder or any
rights, obligations or other Liabilities of any member of the AT&T Broadband
Group to AT&T or to another member of the AT&T Communications Group without
payment of further consideration and AT&T, without the payment of any further
consideration, shall, or shall cause such other member of the AT&T
Communications Group to, assume such rights and obligations. Notwithstanding
the foregoing, unless AT&T Broadband shall so elect, AT&T shall assume all
Liabilities of any nature whatsoever that would constitute AT&T Communications
Liabilities as of the Distribution Date, except for Liabilities of another
member of the AT&T Communications Group.

     SECTION 2.10. Joint Purchasing Arrangements. (a) In the case of existing
purchasing agreements that prior to the Distribution Date provide the AT&T
Broadband Group and the AT&T Communications Group with volume discounts,
subject to applicable law, the parties agree to use their respective reasonable
best efforts so that, to the extent permitted under the terms of such existing
agreements, after the Distribution Date, each Group shall continue to be able
to make purchases and obtain the benefits of the volume discounts. In the case
of any other such contracts, subject to applicable law, the parties will
cooperate reasonably in seeking modifications to such contracts or alternative
or substitute arrangements so that, to the extent practicable after the
Distribution Date, each Group shall continue to be able to make purchases and
obtain the benefits of the volume discounts. Notwithstanding the foregoing, but
subject to the terms of any AT&T Broadband Contract or AT&T Communications
Contract, none of AT&T, AT&T Broadband or their respective Subsidiaries shall
be required to commit to any additional purchases or other obligations, make
any payments or waive any rights in order to effect the foregoing. Each party
hereby agrees to indemnify and hold harmless the other party, and if
applicable, the other party's Subsidiaries, with respect to any losses or
claims arising from such first party's, or such first party's Subsidiaries',
own purchases, commitments or other obligations under any such contracts.

     (b) Until December 31, 2003, subject to applicable law, the parties will
use reasonable commercial efforts to cooperate with each other and, as
applicable, with each other's Subsidiaries, to coordinate and combine their
purchases in cases where they purchase common supplies or use the same
supplier, in each case to the extent permitted by law from time to time. It is
the intent of the parties that this coordination and cooperation will be
focused on achieving more favorable pricing and terms for such supplies and
from such suppliers by aggregating the combined purchases of the parties and
their Subsidiaries. Notwithstanding the foregoing, no party shall be obligated
to make, or cause its Subsidiaries to make, any specific purchases or to use
any specific supplier except to the extent (i) it or one of its Subsidiaries
has previously committed to make a specific purchase or to use a specific
supplier, or (ii) subsequent to the date of this Agreement, it or one of its
Subsidiaries makes a commitment for a specific purchase or to use a specific
supplier. Each party will be responsible for its own and its Subsidiaries'
commitments and its own and its Subsidiaries' purchases and other obligations
made under any common or shared contracts with suppliers and will, in respect
of such commitments, purchases or other obligations, indemnify and hold
harmless the other party and the other party's Subsidiaries that use such
contracts.

     SECTION 2.11. TWE Arrangements. The parties agree to the terms set forth
in Annex I with respect to the partnership interests in TWE held, as of the
date hereof, by MediaOne TWE Holdings, Inc., an AT&T Broadband Entity, and the
TWE Option held by Media One of Colorado, Inc.

                                   ARTICLE 3

                            FINANCIAL RESTRUCTURING

     SECTION 3.01. Liability Management. The Indebtedness included on the AT&T

reflected on the September 30, 2001 balance sheet included in the AT&T
Broadband Financial Statements and the third party Indebtedness identified in
Item 3 of Schedule 6.11 to the Merger Agreement (unless any such Indebtedness
shall have been discharged) (ii) Indebtedness of the members of the AT&T
Broadband Group to members of the AT&T Communications Group and (iii) such
other debt as shall have been approved by the Interim Finance Committee. On the
Distribution Date, the AT&T Broadband Entities may incur additional
Indebtedness to parties (other than to members of the AT&T Communications
Group) in an amount sufficient to (i) pay in full at the Effective Time to AT&T
an amount equal to the Indebtedness owed by any member of the AT&T Broadband
Group to any member of the AT&T Communications Group, (ii) refinance the TOPRS
that may be called for redemption at the Effective Time or shortly thereafter
and (iii) provide appropriate cash reserves to fund the operations of the AT&T
Broadband Entities after the Effective Time. Such Indebtedness shall be
incurred in accordance with Section 9.15 of the Merger Agreement.

     SECTION 3.02. Repayment of Intracompany Indebtedness. AT&T Broadband
agrees that it will pay to AT&T, at the Effective Time and in connection with
the transfer of assets and liabilities hereunder to AT&T Broadband, an amount
of cash equal to the (i)


                                      25



excess of the total Indebtedness of all members of the AT&T Broadband Group to
any member of the AT&T Communications Group over (ii) $30 million, and AT&T
agrees to contribute (or cause its subsidiaries to contribute) such total
Indebtedness to the capital of AT&T Broadband. AT&T agrees that it will repay
or cause to repaid at the Effective Time any Indebtedness of any member of the
AT&T Communications Group to any member of the AT&T Broadband Group. AT&T also
agrees that it will repay or cause to be repaid at the Effective Time any
intercompany receivables owed by AT&T or any AT&T Subsidiary (other than any
AT&T Broadband Entity) to Western Range.

     SECTION 3.03. Note Consents. Subject to the terms and conditions of the
Merger Agreement, AT&T and AT&T Broadband shall each use its reasonable best
efforts to obtain the irrevocable consent to the transactions contemplated
hereby of the holders of at least a majority in aggregate principal amount of
each series of securities at the time outstanding issued under the Indenture,
dated as of September 7, 1990, between American Telephone & Telegraph Company
and The Bank of New York, as trustee.

                                   ARTICLE 4

                                THE DISTRIBUTION

     SECTION 4.01. The Distribution. (a) Subject to Section 4.03, on or prior
to the Record Date, AT&T will deliver to the Agent for the benefit of holders
of record of AT&T Common Stock on the Record Date, a single stock certificate,
endorsed by AT&T in blank, representing the shares of AT&T Broadband Common
Stock issuable in the Distribution (which, together with the shares to be
issued pursuant to the Exchange Agreement, shall constitute all of the shares
of AT&T Broadband Common Stock outstanding as of the Distribution Date), and
shall cause the transfer agent for the shares of AT&T Common Stock to instruct
the Agent to hold in trust (pending conversion of such shares of AT&T Broadband
Common Stock into shares of Parent Common Stock pursuant to the AT&T Broadband
Merger) the appropriate number of such shares of AT&T Broadband Common Stock
(as set forth in Section 4.01(b)) for each such holder or designated transferee
or transferees of such holder. For avoidance of doubt, AT&T will not be
considered a holder of record of AT&T Common Stock as of the Record Date with
respect to any shares of AT&T Common Stock held in its treasury.

     (b) Subject to Section 4.03, each holder of AT&T Common Stock on the
Record Date (or such holder's designated transferee or transferees) will be
entitled to receive in the Distribution a number of shares of AT&T Broadband
Common Stock equal to the number of shares of AT&T Common Stock held by such
holder on the Record Date; provided, that no holder of AT&T Common Stock having
purported to exercise rights pursuant to Section 910 of the NYBCL in respect of
such holder's shares of AT&T Common Stock shall be entitled to receive AT&T
Broadband Common Stock in the Distribution.

     (c) AT&T Broadband and AT&T, as the case may be, will provide to the Agent
all share certificates and any information reasonably required in order to
complete the Distribution on the basis specified above.

     (d) Immediately prior to the Record Date, each of the AT&T Broadband
Subsidiaries, in exchange (the "Subsidiary Preferred Stock Exchange") for all
of the shares of AT&T Subsidiary Preferred Stock held by such AT&T Broadband
Subsidiary immediately prior to the Subsidiary Preferred Stock Exchange, will
receive from AT&T a number of shares of AT&T Broadband Class A Common Stock
(or, if AT&T and AT&T Broadband agree, shares of another class of AT&T
Broadband stock) that has a value equal to the value of the shares of AT&T
Subsidiary Preferred Stock so exchanged. The shares of AT&T Broadband Class A
Common Stock to be issued pursuant to the preceding sentence shall be on the
terms set forth in Exhibit I. Subject to the preceding sentence, AT&T Broadband
agrees to amend its certificate of incorporation prior to the Subsidiary
Preferred Stock Exchange to create the shares of AT&T Broadband Class A Common
Stock necessary to effect the Subsidiary Preferred Stock Exchange. AT&T
Broadband agrees that it shall not, and shall not permit any AT&T Broadband
Subsidiary to, sell, dispose of or otherwise transfer any of the shares of AT&T
Broadband Class A Common Stock that it receives as a result of the Subsidiary
Preferred Stock Exchange, except upon conversion of such shares pursuant to
Article 4 of the Merger Agreement.

     (e) Immediately prior to the Record Date, each of the AT&T Subsidiaries
(other than AT&T Broadband and the AT&T Broadband Subsidiaries), in exchange
(the "Communications Subsidiary Preferred Stock Exchange") for all of the
shares of AT&T Subsidiary Preferred Stock held by such AT&T Subsidiary
immediately prior to the Communications Subsidiary Preferred Stock Exchange,
will receive from AT&T a number of shares of New AT&T Subsidiary Preferred
Stock (or, if AT&T and AT&T Broadband agree, shares of another class of AT&T
stock) that has a value equal to the value of the shares of AT&T Subsidiary
Preferred Stock so exchanged. The shares of New AT&T Subsidiary Preferred Stock
to be issued pursuant to the preceding sentence shall be on the terms set forth
in Exhibit J. Subject to the preceding sentence, AT&T agrees to file a
certificate of designation prior to the Communications Subsidiary Preferred
Stock Exchange to create the shares of New AT&T Subsidiary Preferred Stock
necessary to effect the Communications Subsidiary Preferred Stock Exchange.


                                      26



     (f) At the time of the Distribution, AT&T and AT&T Broadband will comply
with their obligations under the Exchange Agreement, including through the
transfer of shares of AT&T Broadband Common Stock from AT&T to Microsoft as
described therein.

     (g) If the QUIPS Transfer is to occur, AT&T Broadband and AT&T will effect
the QUIPS Transfer.

     (h) Each of AT&T, and AT&T Broadband agrees that in the event that any
holder of shares of AT&T Common Stock purports to exercise any appraisal rights
pursuant to Section 910 of the NYBCL, the parties will cooperate to
appropriately adjust the provisions hereof.

     (i) AT&T agrees that it will take all actions necessary to cancel (i) any
shares of AT&T Broadband stock (or any securities exercisable, exchangeable or
convertible therefor) owned or held by it or any of its Subsidiaries
immediately offer the Distribution so that the only outstanding shares of AT&T
Broadband stock are (A) the shares of AT&T Broadband Common Stock distributed
to the holders of AT&T Common Stock in the Distribution, (B) the shares of AT&T
Broadband Common Stock delivered to Microsoft in the QUIPS Exchange, and (C)
the shares of AT&T Broadband Class A Common Stock held by AT&T Broadband
Subsidiaries and (ii) any shares of AT&T Broadband Common Stock issued in
respect of restricted AT&T Common Stock which pursuant to the Employee Benefits
Agreement will be represented by or converted into AT&T restricted stock units
after the Distribution.

     SECTION 4.02. Actions Prior to the Distribution. (a) As promptly as
reasonably practicable after the execution of this Agreement, subject to the
provisions of the Merger Agreement, AT&T shall prepare and file with the
Commission a proxy statement (the "Proxy Statement") to be sent to shareholders
of AT&T in connection with their meeting to consider the Distribution (the
"AT&T Meeting"), it being understood that the AT&T Meeting may be combined with
any other meeting of shareholders regarding a possible business combination
involving the AT&T Broadband Group.

     (b) As promptly as reasonably practicable after the execution of this
Agreement, subject to the provisions of the Merger Agreement and if required by
applicable law to effect the Distribution, AT&T and AT&T Broadband shall
prepare, and AT&T Broadband shall file with the Commission a registration
statement on Form S-1 or S-4 or any amendment or supplement thereto pursuant to
which shares of AT&T Broadband issuable in the Distribution will be registered

Distribution Registration Statement is required by applicable law to be filed
with the Commission to effect the Distribution, AT&T and AT&T Broadband shall
use their reasonable best efforts to cause the Distribution Registration
Statement to become effective under the Exchange Act as soon after such filing
as reasonably practicable and to keep the Distribution Registration Statement
effective as long as is necessary to consummate the Distribution.

     (c) AT&T and AT&T Broadband shall take all such actions as are reasonably
necessary or appropriate under the federal or state securities or blue sky laws
of the United States (and any comparable laws under any foreign jurisdiction)
in connection with the Distribution.

     SECTION 4.03. Timing of the Distribution. AT&T shall consummate the
Separation and Distribution as soon as practicable (and, in any event, within
five Business Days) after satisfaction (or waiver to the extent permissible) of
all of the conditions to the Separation and the Distribution specified below
(other than conditions that by their nature are to be satisfied at the time of
the Distribution or the Mergers and will in fact be satisfied at such time).
The Separation shall occur on the Distribution Date prior to the Distribution
which shall occur at a time to be mutually agreed on the Distribution Date.
With the consent of Comcast, which consent shall not be unreasonably withheld,
AT&T may effect the Separation and/or the Distribution on different dates or
different times than provided for in the preceding sentence. The obligation of
AT&T to consummate the Separation and the Distribution and the other
transactions contemplated by this Agreement is subject to the satisfaction (or
waiver to the extent permissible) of the following conditions:

          (a) If required by applicable law to effect the Distribution, the
     Distribution Registration Statement shall have been filed and declared
     effective by the Commission, and there shall be no stop-order in effect
     with respect thereto;

          (b) The actions and filings with regard to material federal or state
     securities and blue sky laws of the United States (and any comparable laws
     under any foreign jurisdictions) described in Section 4.02(c) shall have
     been taken and, where applicable, become effective or been accepted;

          (c) Any Governmental Approvals and Consents including those listed on
     Schedule 4.03(c) necessary to consummate the


                                      27



     Distribution in the manner contemplated by this Agreement shall have been
     obtained and be in full force and effect, except for such Governmental
     Approvals and Consents the failure of which to obtain would not,
     individually or in the aggregate, reasonably be expected to have an AT&T
     Broadband Material Adverse Effect or an AT&T Material Adverse Effect;

          (d) All conditions to permit the Distribution to qualify as a
     tax-free distribution to AT&T, AT&T Broadband and shareholders of AT&T
     shall, to the extent applicable as of the time of the Distribution, be
     satisfied and there shall be no event or condition that is likely to cause
     any of such conditions not to be satisfied as of the time of the
     Distribution or thereafter;

          (e) No order, injunction or decree issued by any court or agency of
     competent jurisdiction or other material legal restraint or prohibition
     preventing the consummation of the Separation or the Distribution or any
     of the other transactions contemplated by this Agreement or any other
     Ancillary Agreement shall be in effect and the Separation and Distribution
     shall be in compliance in all material respects with applicable law;

          (f) This Agreement shall not have been terminated;

          (g) The supplemental private letter ruling or rulings from the IRS or
     the opinion described in Section 10.01(j) of the Merger Agreement shall
     have been obtained and shall continue in effect;

          (h) The Distribution shall have been approved by the affirmative vote
     of shareholders holding a majority of the voting power of the issued and
     outstanding shares of AT&T Common Stock at the AT&T Meeting; and

          (i) The conditions specified in Sections 10.01 and 10.02 (other than
     Section 10.01(i)) of the Merger Agreement shall have been satisfied (or
     waived to the extent permissible).

The foregoing conditions are for the sole benefit of AT&T and shall not give
rise to or create any duty on the part of AT&T or the Board of Directors of
AT&T to waive or not waive any such condition.

     SECTION 5.01. Release of Pre-Closing Claims. (a) Except as provided in

or in equity (including any right of contribution), whether arising under any
contract or agreement, by operation of law or otherwise, existing or arising
from any acts or events occurring or failing to occur or alleged to have
occurred or to have failed to occur or any conditions existing or alleged to
have existed on or before the Distribution Date, whether or not known as of the
Distribution Date, including in connection with the transactions and all other
activities to implement either the Separation or the Distribution.

     (b) Except as provided in Section 5.01(c), effective as of the
Distribution Date, AT&T Broadband, for itself and each other wholly owned
member of the AT&T Broadband Group (other than any member of the AT&T
Communications Group) and their respective successors and assigns, and all
shareholders, directors, officers, members, agents or employees of any wholly
owned member of the AT&T Broadband Group (in each case, in their respective

(other than any member of the AT&T Broadband Group), their respective
successors and assigns, and all shareholders, directors, officers, members,
agents or employees of any wholly owned member of the AT&T Communications Group
(in each case, in their respective capacities as such), and their respective

Liabilities whatsoever, whether at law or in equity (including any right of
contribution), whether arising under any contract or agreement, by operation of
law or otherwise, existing or arising from any acts or events occurring or
failing to occur or alleged to have occurred or to have failed to occur or any
conditions existing or alleged to have existed on or before the Distribution
Date, whether or not known as of the Distribution Date, including in


                                      28



connection with the transactions and all other activities to implement either
the Separation or the Distribution.

     (c) Nothing contained in Section 5.01(a) or 5.01(b) shall impair any right
of any Person to enforce this Agreement, any other Ancillary Agreement or any
agreements, arrangements, commitments or understandings that are specified in
Section 2.04(b) or the applicable Schedules thereto not to terminate as of the
Distribution Date, in each case in accordance with its terms. Nothing contained

          (i) any Liability provided in or resulting from any agreement among
     any members of the AT&T Broadband Group or the AT&T Communications Group
     that is specified in Section 2.04(b) or the applicable Schedules thereto
     as not to terminate as of the Distribution Date, or any other Liability
     specified in such Section 2.04(b) as not to terminate as of the
     Distribution Date;

          (ii) any Liability, contingent or otherwise, assumed, transferred,
     assigned or allocated to the Group of which such Person is a member in
     accordance with, or any other Liability of any member of any Group under,
     this Agreement or any other Ancillary Agreement;

          (iii) any Liability arising from or relating to the sale, lease,

     purchased, obtained or used in the ordinary course of business by a member
     of one Group from a member of any other Group prior to the Distribution
     Date;

          (iv) any Liability for payment for goods, services or property
     purchased, obtained or used in the ordinary course of business by a member
     of one Group from a member of any other Group prior to the Distribution
     Date or any related refund claims; or

          (v) any Liability the release of which would result in the release of
     any Person other than a Person released pursuant to this Section 5.01;
     provided that the parties agree not to bring suit or permit any of their
     Subsidiaries to bring suit against any Person with respect to any
     Liability to the extent that such Person would be released with respect to
     such Liability by this Section 5.01 but for the provisions of this clause
     (v).

     (d) AT&T shall not make, and shall not permit any member of the AT&T
Communications Group to make, any claim or demand, or commence any Action
asserting any claim or demand, including any claim of contribution or any
indemnification, against AT&T Broadband or any wholly owned member of the AT&T
Broadband Group, or any other Person released pursuant to Section 5.01(a), with
respect to any Liabilities released in respect of such Person pursuant to
Section 5.01(a). AT&T Broadband shall not make, and shall not permit any member
of the AT&T Broadband Group to make, any claim or demand, or commence any
Action asserting any claim or demand, including any claim of contribution or
any indemnification, against AT&T or any wholly owned member of the AT&T
Communications Group, or any other Person released pursuant to Section 5.01(b),
with respect to any Liabilities in respect of such Person released pursuant to
Section 5.01(b).

     (e) At any time, at the request of any other party, each party shall cause
each member of its respective Group to execute and deliver releases reflecting
the provisions of this Section 5.01.

     SECTION 5.02. Indemnification by AT&T. Except as provided in Section 5.04,
following the Distribution Date, AT&T shall indemnify, defend and hold harmless
AT&T Broadband, each member of the AT&T Broadband Group, AT&T Comcast (but only
in respect of subsections (d) and (e)) and each of their respective directors,
officers and employees, and each of the heirs, executors, successors and
assigns of any of the foregoing (collectively, the "AT&T Broadband
Indemnitees"), from and against any and all Liabilities (or in the case of
subsection (d), 50% of any and all Liabilities) of the AT&T Broadband
Indemnitees relating to, arising out of or resulting from any of the following
items (without duplication):

          (a) the failure of AT&T or any other member of the AT&T
     Communications Group or any other Person to pay, perform or otherwise
     promptly discharge any AT&T Communications Liabilities, or AT&T
     Communications Contract, in accordance with their respective terms,
     whether prior to or after the Distribution Date or the date hereof;

          (b) the AT&T Communications Business, any AT&T Communications Asset
     or any AT&T Communications Contract (except to the extent such Liabilities
     arise out of any breach by AT&T or any of its Subsidiaries prior to the
     Distribution Date of any AT&T Communications Contract entered into in
     connection with the separation, divestiture or termination of LMC and its
     Subsidiaries);

          (c) any breach by AT&T or any member of the AT&T Communications Group
     of this Agreement or any of the other Ancillary


                                      29



     Agreements;

          (d) any untrue statement or alleged untrue statement of a material
     fact or omission or alleged omission to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, with respect to all information contained in any Registration
     Statement, except to the extent such information relates to AT&T's
     proposal to create a tracking stock with respect to its consumer services
     business as contemplated by Section 11.06, AT&T's proposal to authorize a
     reverse stock split or any other AT&T 2002 annual meeting proposal other
     than the AT&T proposal to approve and adopt the Merger Agreement and the
     transactions contemplated by the Merger Agreement or the proposal in
     respect of the AT&T Parent Charter Approval (as defined in the Merger
     Agreement) (any Action relating to the matters set forth in this Section
     5.02(d) or Section 5.03(d), a "Registration Statement Claim"); and

        (e) any untrue statement or alleged untrue statement of a material fact
    or omission or alleged omission to state a material fact required to be
    stated therein or necessary to make the statements therein not misleading,
    with respect to all information contained in any Registration Statement to
    the extent such information relates to AT&T's proposal to create a tracking
    stock with respect to its consumer services business as contemplated by
    Section 11.06, AT&T's proposal to authorize a reverse stock split or any
    other AT&T 2002 annual meeting proposal other than the AT&T proposal to
    approve and adopt the Merger Agreement and the transactions contemplated by
    the Merger Agreement or the proposal in respect of the AT&T Parent Charter
    Approval (as defined in the Merger Agreement).

    SECTION 5.03. Indemnification by AT&T Broadband. Except as provided in
Section 5.04, following the Distribution Date, AT&T Broadband shall indemnify,
defend and hold harmless AT&T, each member of the AT&T Communications Group and
each of their respective directors, officers and employees, and each of the
heirs, executors, successors and assigns of any of the foregoing (collectively,
the "AT&T Indemnitees"), from and against any and all Liabilities (or in the
case of subsection (d), 50% of any and all Liabilities) of the AT&T Indemnitees
relating to, arising out of or resulting from any of the following items
(without duplication):

          (a) the failure of AT&T Broadband or any other member of the AT&T
     Broadband Group or any other Person to pay, perform or otherwise promptly
     discharge any AT&T Broadband Liabilities, or AT&T Broadband Contract, in
     accordance with their respective terms, whether prior to or after the
     Distribution Date or the date hereof;

          (b) the AT&T Broadband Business, any AT&T Broadband Asset or any AT&T
     Broadband Contract;

          (c) any breach by AT&T Broadband or any member of the AT&T Broadband
     Group of this Agreement or any of the other Ancillary Agreements;

          (d) any untrue statement or alleged untrue statement of a material
     fact or omission or alleged omission to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, with respect to all information contained in any Registration
     Statement, except to the extent such information relates to AT&T's
     proposal to create a tracking stock with respect to its consumer services
     business as contemplated by Section 11.06, AT&T's proposal to authorize a
     reverse stock split or any other AT&T 2002 annual meeting proposal other
     than the AT&T proposal to approve and adopt the Merger Agreement and the
     transactions contemplated by the Merger Agreement or the proposal in
     respect of the AT&T Parent Charter Approval (as defined in the Merger
     Agreement); and

          (e) if neither the QUIPS Exchange nor the QUIPS Transfer occurs, any
     Liabilities relating to, arising out of or resulting from any Actions
     commenced by Microsoft claiming that the transactions contemplated hereby
     or by the Merger Agreement violate the terms of the QUIPS; provided that
     for purposes hereof, in the event that AT&T is required to repay the QUIPS
     as a result of such Action, the indemnified Liability hereunder in respect
     of such repayment shall be reduced by the amount of the QUIPS Fair Market
     Value plus any accrued interest on the QUIPS since the date as of which
     the QUIPS Fair Market Value was determined (any such Action, a "Microsoft
     QUIPS Claim").

     Notwithstanding the foregoing, AT&T Broadband shall have no obligation to
indemnify, defend and hold harmless any AT&T Indemnitee from and against any
Liabilities arising out of any breach by At Home or any of its Subsidiaries of
any At Home Contract.

     SECTION 5.04. Indemnification Obligations Net of Insurance Proceeds and
Other Amounts. (a) The parties intend that any indemnification or reimbursement
obligation pursuant to this Article 5 will be net of Insurance Proceeds that
actually reduce the amount of the Liability. Accordingly, the amount which any
party (an "Indemnifying Party") is required to pay to any Person entitled to
indemnification hereunder (an "Indemnitee") will be reduced by any Insurance
Proceeds theretofore actually recovered by


                                      30



or on behalf of the Indemnitee in reduction of the related Liability. If an
Indemnitee receives a payment (an "Indemnity Payment") required by this
Agreement from an Indemnifying Party in respect of any Liability and
subsequently receives Insurance Proceeds, then the Indemnitee will pay to the
Indemnifying Party an amount equal to the excess of the Indemnity Payment
received over the amount of the Indemnity Payment that would have been due if
the Insurance Proceeds had been received, realized or recovered before the
Indemnity Payment was made.

     (b) An insurer who would otherwise be obligated to defend or make payment
in response to any claim shall not be relieved of the responsibility with
respect thereto or, solely by virtue of the indemnification provisions hereof,
have any subrogation rights with respect thereto, it being expressly understood
and agreed that no insurer or any other third party shall be entitled to a
"windfall" (i.e., a benefit it would not be entitled to receive in the absence
of the indemnification provisions) by virtue of the indemnification provisions
hereof.

     (c) With respect to all policies of insurance with insurance companies
other than American Ridge and Western Range, the parties agree to act in good
faith and to use their reasonable best efforts to preserve and maximize the
insurance benefits due to be provided thereunder and to cooperate with one
another as necessary to permit each other to access or obtain the benefits
under those policies, provided, however, that nothing in this Section 5.04
shall be construed to prevent any party or any other Person from asserting
claims for insurance benefits or accepting insurance benefits provided by the
policies. The parties agree to exchange information upon reasonable request of
the other party regarding requests that they have made for insurance benefits,
notices of claims, occurrences and circumstances that they have submitted to
the insurance companies or other entities managing the policies, responses they
have received from those insurance companies or entities, including any
payments they have received from the insurance companies and any agreements by
the insurance companies to make payments, and any other information that the
parties may need to determine the status of the insurance policies and the
continued availability of benefits thereunder.

     SECTION 5.05. Procedures for Indemnification of Third Party Claims. (a) If
an Indemnitee shall receive notice or otherwise learn of the assertion by a
Person (including any Governmental Authority) who is not a member of the AT&T
Broadband Group or the AT&T Communications Group of any claim or of the
commencement by any such Person of any Action (collectively, a "Third Party
Claim") with respect to which an Indemnifying Party may be obligated to provide
indemnification to such Indemnitee pursuant to Section 5.02 or 5.03, or any
other Section of this Agreement or any Ancillary Agreement (except as otherwise
provided therein), such Indemnitee shall give such Indemnifying Party written
notice thereof promptly after becoming aware of such Third Party Claim. Any
such notice shall describe the Third Party Claim in reasonable detail.
Notwithstanding the foregoing, the failure of any Indemnitee to give notice as
provided in this Section 5.05(a) shall not relieve the related Indemnifying
Party of its obligations under this Article 5, except to the extent that such
Indemnifying Party is actually prejudiced by such failure to give notice.

     (b) An Indemnifying Party may elect to defend (and, unless the
Indemnifying Party has specified any reservations or exceptions, to seek to
settle or compromise), at such Indemnifying Party's own expense (including
allocated costs of in-house counsel and other personnel) and by such
Indemnifying Party's own counsel, any Third Party Claim. Within 30 days after
the receipt of notice from an Indemnitee in accordance with Section 5.05(a) (or
sooner, if the nature of such Third Party Claim so requires), the Indemnifying
Party shall notify the Indemnitee of its election whether the Indemnifying
Party will assume responsibility for defending such Third Party Claim, which
election shall specify any reservations or exceptions. After notice from an
Indemnifying Party to an Indemnitee of its election to assume the defense of a
Third Party Claim, such Indemnitee shall have the right to employ separate
counsel and to participate in (but not control) the defense, compromise, or
settlement thereof, but the fees and expenses of such counsel shall be the
expense of such Indemnitee, except as set forth in the next sentence. In the
event that the Indemnifying Party has elected to assume the defense of the
Third Party Claim but has specified and continues to assert, any reservations
or exceptions in such notice, then, in any such case, the reasonable fees and
expenses of one separate counsel for all Indemnitees shall be borne by the
Indemnifying Party.

     (c) If an Indemnifying Party elects not to assume responsibility for
defending a Third Party Claim, or fails to notify an Indemnitee of its election
as provided in Section 5.05(b), such Indemnitee may defend such Third Party
Claim at the cost and expense (including allocated costs of in-house counsel
and other personnel) of the Indemnifying Party.

     (d) Unless the Indemnifying Party has failed to assume the defense of the
Third Party Claim in accordance with the terms of this Agreement, no Indemnitee
may settle or compromise any Third Party Claim without the consent of the
Indemnifying Party.

     (e) No Indemnifying Party shall consent to any settlement of the Third
Party Claim without the consent of the Indemnitee if the effect thereof is to
permit any injunction, declaratory judgment, other order or other nonmonetary
relief to be entered, directly or indirectly, against any Indemnitee.


                                      31



     (f) The provisions of Section 5.05 and Section 5.06 shall not apply to
Taxes (which are covered by the Tax Sharing Agreement) or to matters covered by
Sections 6.02 and 6.03.

     (g) Notwithstanding anything in this Agreement to the contrary, and
subject to any applicable provision of the AWS separation agreements, if either
party is named in any Action relating to any At Home Matter, Specified Matter,
Specified Transaction or Registration Statement Claim, that party shall be
entitled to assume and control its own defense and to employ its own counsel.
Neither party shall settle any such Action without the consent of the other
party (which consent will not be unreasonably withheld). All legal and other
fees (including allocated cost of in-house counsel and other personnel)
incurred in connection therewith shall be divided 50/50 between AT&T and AT&T
Broadband.

     SECTION 5.06. Additional Matters. (a) Any claim on account of a Liability
that does not result from a Third Party Claim shall be asserted by written
notice given by the Indemnitee to the related Indemnifying Party. Such
Indemnifying Party shall have a period of 30 days after the receipt of such
notice within which to respond thereto. If such Indemnifying Party does not
respond within such 30-day period, such Indemnifying Party shall be deemed to
have refused to accept responsibility to make payment. If such Indemnifying
Party does not respond within such 30-day period or rejects such claim in whole
or in part, such Indemnitee shall be free to pursue such remedies as may be
available to such party as contemplated by this Agreement and the other
Ancillary Agreements.

     (b) In the event of payment by or on behalf of any Indemnifying Party to
any Indemnitee in connection with any Third Party Claim, such Indemnifying
Party shall be subrogated to and shall stand in the place of such Indemnitee as
to any events or circumstances in respect of which such Indemnitee may have any
right, defense or claim relating to such Third Party Claim against any claimant
or plaintiff asserting such Third Party Claim or against any other person but
only to the extent related to such payment. Such Indemnitee shall cooperate
with such Indemnifying Party in a reasonable manner, and at the cost and
expense (including allocated costs of in-house counsel and other personnel) of
such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

     (c) In the event of an Action in which the Indemnifying Party is not a
named defendant, if either the Indemnitee or Indemnifying Party shall so
request, the parties shall endeavor to substitute the Indemnifying Party for
the named defendant, if at all practicable. If such substitution or addition
cannot be achieved for any reason or is not requested, the named defendant
shall allow the Indemnifying Party to manage the Action as set forth in this
Section 5.06 and the Indemnifying Party shall fully indemnify the named
defendant against all reasonable costs of defending the Action (including court
costs, sanctions imposed by a court, attorneys' fees, experts' fees and all
other external expenses, and the allocated costs of in-house counsel and other
personnel), the costs of any judgment or settlement, and the cost of any
interest or penalties relating to any judgment or settlement.

     SECTION 5.07. Remedies Cumulative. The remedies provided in this Article 5
shall be cumulative and shall not preclude assertion by any Indemnitee of any
other rights or the seeking of any and all other remedies against any
Indemnifying Party.

     SECTION 5.08. Survival of Indemnities. The rights and obligations of each
of AT&T, AT&T Broadband and their respective Indemnitees under this Article 5
shall survive the sale or other transfer by any party of any Assets or
businesses or the assignment by it of any Liabilities.

                                   ARTICLE 6

                      INSURANCE AND CERTAIN OTHER MATTERS

     SECTION 6.01. Insurance Matters. (a) The parties intend that both AT&T and
AT&T Broadband and each other member of the AT&T Communications Group and the
AT&T Broadband Group, after the Distribution Date, shall be
successors-in-interest to and retain all rights and interest (whether known,
unknown, contingent or otherwise) that each has as of the Distribution Date
under any Insurance Policy issued to and/or providing coverage to AT&T, as it
existed immediately prior to the Distribution Date, or any of its Subsidiaries
or Affiliates, and any agreements related to such Insurance Policies executed
and delivered prior to the Distribution Date, including any rights or interests
each has, as an insured, named insured, or additional named insured,
Subsidiary, Affiliate, division or department, to avail itself of any benefit
under any such Insurance Policy or any such agreement related to such policy as
in effect prior to the Distribution Date. The provisions of this Agreement are
not intended to relieve any insurer of any Liability under any policy.
Notwithstanding the foregoing, no member of the AT&T Broadband Group or the
AT&T Communications Group shall be deemed to have made any representation or
warranty as to the availability of any Insurance Policy or the rights and
benefits provided thereunder.


                                      32



     (b) This Agreement shall not be considered as an attempted assignment (if
such an assignment would be prohibited or would otherwise adversely affect the
rights of the insured parties under such policies) of any rights or interest
under any policy of insurance or as a contract of insurance and shall not be
construed to waive any right or remedy of any member of the AT&T Broadband
Group or the AT&T Communications Group in respect of any Insurance Policy or
any other contract or policy of insurance.

     (c) Each of AT&T and AT&T Broadband does hereby, for itself and each other
member of the AT&T Communications Group and the AT&T Broadband Group, agree
that, as and to the extent necessary to give effect to Section 6.01(a), it will
assign any chose in action, claim, right or benefit under an Insurance Policy.

     (d) AT&T Broadband does hereby, for itself and each other member of the
AT&T Broadband Group, agree that from and after the Distribution Date, AT&T
Broadband and each other member of the AT&T Broadband Group releases any and
all insurance or other claims that it may have against American Ridge and
Subsidiaries of American Ridge, whether known or unknown.

     (e) AT&T does hereby, for itself and each other member of the AT&T
Communications Group, agree that (i) no member of the AT&T Broadband Group or
any AT&T Broadband Indemnitee shall have any Liability whatsoever as a result
of the insurance policies and practices of AT&T and its Affiliates as in effect
or undertaken at any time prior to the Distribution Date, including as a result
of the level or scope of any such insurance, the creditworthiness of any
insurance carrier, the terms and conditions of any policy, the adequacy or
timeliness of any notice to any insurance carrier with respect to any claim or
potential claim or otherwise and (ii) from and after the Distribution Date,
AT&T and each other member of the AT&T Communications Group releases any and
all insurance or other claims that it may have against Western Range and
Subsidiaries of Western Range, whether known or unknown.

     (f) Each of AT&T and AT&T Broadband does hereby, for itself and each other
member of the AT&T Communications Group and the AT&T Broadband Group, agree
that all duties and obligations under any Insurance Policy, including the
fulfillment of any conditions and the payment of any deductibles, retentions,
co-insurance payment or retrospective premiums, that correspond in any way with
or may be necessary to perfect, preserve or maintain an insuredIs right to
obtain benefits under that Insurance Policy, will be performed by the insured
that is seeking the benefits, subject to the indemnification provisions of
Article 5. In the event members of both Groups have claims under a given
policy, any deductibles, retentions, co-insurance payments, retrospective
premiums, caps, limitations on average and similar items will be appropriately
allocated between such parties based on the recoveries they would have obtained
in the absence of such items.

     SECTION 6.02. Certain Post-Distribution Transactions and Related Matters.
(a) Each of AT&T and AT&T Broadband agrees that, until 12 months after the date
of the Distribution, it will (i) maintain its status as a company engaged in
the active conduct of a trade or business and (ii) not engage in any
transaction that would result in it ceasing to be a company engaged in the
active conduct of a trade or business, as defined in Section 355(b) of the
Code.

     (b) Each of AT&T and AT&T Broadband further agrees that, until 25 months
after the date of the Distribution, it will not, except as expressly
contemplated by this Agreement or the Merger Agreement, (i) enter into any
Proposed Acquisition Transaction or, to the extent AT&T or AT&T Broadband, as
the case may be, has the right to prohibit any Proposed Acquisition
Transaction, permit any Proposed Acquisition Transaction to occur (whether by
(A) redeeming rights under a shareholders rights plan, (B) finding a tender
offer to be a "permitted offer" under any such plan or otherwise causing any
such plan to be inapplicable or neutralized with respect to any Proposed
Acquisition Transaction, or (C) approving any Proposed Acquisition Transaction,
whether for purposes of any interested shareholder statute, any "fair price" or
other provision of its respective charter or bylaws or otherwise), (ii)
liquidate or partially liquidate, (iii) in a single transaction or series of
related transactions, sell or transfer all or substantially all of the assets
of AT&T or the assets of the AT&T Broadband Group that were transferred to AT&T
Broadband prior to the Distribution, as the case may be, (iv) redeem or
otherwise repurchase (directly or through an Affiliate) any of its stock, (v)
enter into any transaction or series of transactions as a result of which any
Person would acquire, or have the right to acquire, from AT&T or AT&T
Broadband, as the case may be, or one of their respective Affiliates, a number
of shares of stock that would comprise more than 5% of (A) the value of all
outstanding shares of stock of as of the date of such transaction, or in the
case of a series of transactions, the date of the last transaction of such
series, or (B) the voting power of the issued and outstanding shares of stock
as of the date of such transaction, or in the case of a series of transactions,
the date of the last transaction of such series or (vi) take any other action
or actions (including any action or transaction that would be inconsistent with
any representation made in the Tax Opinions/Rulings) that in the aggregate (and
taking into account any other transactions described in this subparagraph (b))
would be reasonably likely to have the effect of causing or permitting one or
more Persons to acquire directly or indirectly stock representing a 50 percent
or greater interest (within the meaning of Section 355(e) of the Code) in AT&T
or AT&T Broadband or otherwise jeopardize the non-recognition of taxable gain
or loss for U.S. federal income tax purposes to AT&T, AT&T Affiliates and
shareholders of AT&T in connection with the Separation and Distribution, unless
prior to taking any such action set forth in the foregoing clauses (i) through
(vi), AT&T (with respect to AT&T


                                      33



Broadband) and AT&T Broadband (with respect to AT&T) has determined, in its
sole and absolute discretion, which discretion shall be exercised in good faith
solely to preserve the tax-free status of the Separation and Distribution, that
such action or actions would not result in a Spin-Off Disqualification.
Anything in the preceding sentence to the contrary notwithstanding, a
transaction described in clauses (i) through (vi) of the preceding sentence
shall not require the determination of the other party in the event that as of
the date immediately preceding such transaction there has not been issued and,
when taken together with the shares to be issued pursuant to the transaction,
there will not be issued, directly or indirectly, pursuant to a Proposed
Acquisition Transaction or otherwise, including as a consequence of the Merger
Agreement, taking into account for such purpose all share transactions which
would be taken into account under Section 355(e) of the Code assuming all such
issuances were considered to be "part of a plan or series of related
transactions" with the Distribution number of shares in excess of 30 percent of
(A) the value of all outstanding shares of stock as of the date of such
transaction, or in the case of a series of transactions, the date of the last
transaction of such series, or (B) the voting power of the issued and
outstanding shares of stock as of the date of such transaction, or in the case
of a series of transactions, the date of the last transaction of such series.
"Proposed Acquisition Transaction" means a transaction or series of
transactions as a result of which AT&T or AT&T Broadband would merge or
consolidate with any other Person or pursuant to which any Person or any group
of related Persons would acquire, or have the right to acquire, directly or
indirectly, from one or more holders of outstanding shares of stock of a number
of shares of stock that would comprise more than 5% of (A) the value of all
outstanding shares of stock as of the date of such transaction, or in the case
of a series of transactions, the date of the last transaction of such series,
or (B) the voting power of the issued and outstanding shares of stock as of the
date of such transaction, or in the case of a series of transactions, the date
of the last transaction of such series. "Tax Opinions/Rulings" means,
collectively, the opinions of tax counsel and the rulings by the IRS
deliverable to AT&T in connection with the transactions contemplated by this
Agreement.

     (c) If one party (the "Issuing Party") notifies the other (the "Other
Party") that it desires to take one of the actions described in clauses (i)
through (vi) of Section 6.02(b) (the "Notified Action") and the Other Party
declines to exercise its discretion pursuant to Section 6.02(b) to permit the
Issuing Party to take such Notified Action, the Issuing Party, in its
reasonable discretion, may elect to seek a Subsequent Tax Opinion/Ruling that
would permit the Issuing Party to take the Notified Action, and the Other Party
shall cooperate in connection with such efforts; provided, however, that the
reasonable costs and expenses of obtaining any such Subsequent Tax
Opinion/Ruling shall be borne by the Issuing Party. "Subsequent Tax
Opinion/Ruling" means either (i) an unqualified opinion of counsel jointly
selected by the Issuing Party and the Other Party confirming that, as a
consequence of the consummation of the Notified Action, no income, gain or loss
for U.S. federal income tax purposes will be recognized by AT&T, the
shareholders or former shareholders of AT&T, or any AT&T Affiliate with respect
to the Separation and Distribution or (ii) an IRS private letter ruling to the
same effect that, after reasonable due diligence conducted by the Other Party,
are in form and substance reasonably satisfactory to the Other Party.

     (d) Notwithstanding anything to the contrary herein or any provision of
the Tax Sharing Agreement to the contrary, if there is a determination (as
defined in Section 1313 of the Code) that a Spin-Off Disqualification has
occurred, then AT&T Broadband shall indemnify and hold harmless AT&T and each
member of the consolidated group of which AT&T is a member from and against one
half of all Tax Related Losses imposed upon or incurred by AT&T or any member
of its group as a result of the Spin-Off Disqualification; provided, however,
that AT&T Broadband shall indemnify and hold harmless AT&T and each member of
the consolidated group of which AT&T is a member from and against any and all
Tax Related Losses imposed upon or incurred by AT&T or any member of its group
as a result of the Spin-Off Disqualification if such Spin-Off Disqualification
would not have occurred but for an AT&T Broadband Action and; provided,
further, that AT&T Broadband shall have no obligation to indemnify AT&T or any
member of the consolidated group of which AT&T is a member if the Spin-Off
Disqualification would not have occurred but for an AT&T Communications Action.
"AT&T Broadband Action" means (i) any transaction with respect to the stock or
assets of AT&T Broadband that occurs after the Distribution, (ii) AT&T
Broadband's failure to maintain its status as a company engaged in the active
conduct of a trade or business, and (iii) the failure of any representation
made by AT&T Broadband with respect to AT&T Broadband or the AT&T Broadband
Business, and the plans, proposals, intentions and policies of AT&T Broadband
after the Separation and Distribution in connection with a Subsequent Tax
Opinion/ Ruling to be true and correct in all material respects. "AT&T
Communications Action" means (i) any transaction with respect to the stock or
assets of AT&T that occurs after the Distribution, (ii) AT&T's failure to
maintain its status as a company engaged in the active conduct of a trade or
business, and (iii) the failure of any representation made by AT&T with respect
to AT&T or the AT&T Communications Business and the plans, proposals,
intentions and policies of AT&T after the Separation and Distribution in
connection with the Tax Opinions/Rulings or a Subsequent Tax Opinion/Ruling to
be true and correct in all material respects. The delivery of any Subsequent
Tax Opinion/Ruling shall not affect either party's rights and obligations with
respect to indemnification under this Section 6.02(d). "Tax Related Losses"
means (A) all federal, state and local Taxes (including interest and penalties
thereon) imposed pursuant to any settlement, final determination, judgment or
otherwise; (B) all accounting, legal and other professional fees, and court
costs incurred in connection with such taxes; and (C) all costs and expenses
that may result from adverse tax consequences to AT&T (including all costs,
expenses and damages associated with shareholder litigation or controversies)
payable by AT&T or AT&T Affiliates.


                                      34



     SECTION 6.03. Procedure for Indemnification for Tax Liabilities. (a) If
AT&T receives notice of the assertion of any claim, suit, arbitration, inquiry,
proceeding or investigation by or before any court, governmental or other
regulatory or administrative agency or commission or any arbitration tribunal
asserted by a Person other than AT&T or any AT&T Affiliate or AT&T Broadband or
any AT&T Broadband Affiliate that gives rise to a right of indemnification
hereunder (a "Third Party Tax Claim") with respect to which AT&T Broadband may
be obligated under Section 6.02(d) to provide indemnification, AT&T shall give
AT&T Broadband notice thereof (together with a copy of such Third Party Tax
Claim, process or other legal pleading) promptly after becoming aware of such
Third Party Tax Claim; provided, however, that the failure of AT&T to give
notice as provided in this Section shall not relieve AT&T Broadband of its
obligations under Section 6.02(d), except to the extent that AT&T Broadband is
actually prejudiced by such failure to give notice. Such notice shall describe
such Third-Party Tax Claim in reasonable detail.

     (b) (i) Notwithstanding any provision to the contrary contained in the Tax
Sharing Agreement, AT&T and AT&T Broadband shall jointly control the defense
of, and cooperate with each other with respect to defending, any Third Party
Tax Claim with respect to which AT&T Broadband may be obligated under Section
6.02(d) to provide indemnification; provided that AT&T Broadband shall forfeit
such joint control right with respect to a particular Third Party Tax Claim if
AT&T Broadband or any AT&T Broadband Affiliate makes any public statement or
filing, or takes any action (including, but not limited to, the filing of any
submission or pleading, or the giving of a deposition or production of
documents, in any administrative or court proceeding) in connection with such
Third Party Tax Claim that is inconsistent in a material respect with any
representation or warranty made by AT&T Broadband in the Agreement, the Tax
Opinions/Rulings, the Representation Letter or a Subsequent Tax Opinion/Ruling
and; provided, further, that AT&T shall forfeit such joint control right with
respect to a particular Third Party Tax Claim if AT&T or any AT&T Affiliate
makes any public statement or filing, or takes any action (including, but not
limited to, the filing of any submission or pleading, or the giving of a
deposition or production of documents, in any administrative or court
proceeding) in connection with such Third Party Tax Claim that is inconsistent
in a material respect with any representation or warranty made by AT&T in the
Agreement, the Tax Opinions/Rulings, the Representation Letter or a Subsequent
Tax Opinion/Ruling.

     (ii) AT&T and AT&T Broadband shall exercise their rights to jointly
control the defense of any such Third Party Tax Claim solely for the purpose of
defeating such Third Party Tax Claim and, unless required by applicable law,
neither AT&T nor AT&T Broadband shall make any statements or take any actions
that could reasonably result in the shifting of liability for any Tax Related
Losses arising out of such Third Party Tax Claim from the party making such
statement or taking such action (or any of its Affiliates) to the other party
(or any of its Affiliates).

     (iii) Statements made or actions taken by either AT&T or AT&T Broadband in
connection with the defense of any such Third Party Tax Claim shall not
prejudice the rights of such party in any subsequent action or proceeding
between the parties.

     (iv) If either AT&T or AT&T Broadband fails to jointly defend any such
Third Party Tax Claim, the other party shall solely defend such Third Party Tax
Claim and the party failing to jointly defend shall use commercially reasonable
efforts to cooperate with the other party in its defense of such Third Party
Tax Claim; provided, however, that neither party may compromise or settle any
such Third Party Tax Claim without the prior written consent of the other
party, which consent shall not be unreasonably withheld or delayed. All costs
and expenses of either party in connection with, and during the course of, the
joint control of the defense of any such Third Party Tax Claim shall be
initially paid by the party that incurs such costs and expenses. Such costs and
expenses shall be reallocated and reimbursed in accordance with the respective
indemnification obligations of the parties at the conclusion of the defense of
such Third Party Tax Claim.

     (c) (i) If there is a determination (as defined in Section 1313 of the
Code) that a Spin-Off Disqualification has occurred, AT&T and AT&T Broadband
shall attempt in good faith to resolve any disagreement with respect to whether
there is an indemnification obligation pursuant to Section 6.02(d). If the
parties cannot agree by the tenth Business Day following the determination (the
"Dispute Date"), then the liability shall initially be determined as follows:
Within 20 days of the Dispute Date, AT&T and AT&T Broadband shall each appoint
one arbitrator. The two arbitrators so appointed shall appoint a third
arbitrator within 30 days of the Dispute Date. If either party shall fail to
appoint an arbitrator within such 20-day period, the arbitration shall be
conducted by the sole arbitrator appointed by the other party. Whether selected
by AT&T, AT&T Broadband or otherwise, each arbitrator selected to resolve such
dispute shall be a tax attorney who is generally recognized in the tax
community as a qualified and competent tax practitioner with experience in the
tax area involved in the issue to be resolved. Such arbitrators shall be
empowered to determine initially whether or not AT&T Broadband is required to
indemnify AT&T pursuant to Section 6.02(d) hereunder. Each of AT&T and AT&T
Broadband shall bear 50% of the aggregate expenses of the arbitrators (or sole
arbitrator). The decision of the arbitrators shall be rendered no later than 90
days from the Dispute Date.


                                      55



     (ii) On the tenth Business Day following the determination that there has
been a Spin-Off Disqualification, if AT&T Broadband agrees that it has an
indemnification obligation, AT&T Broadband shall pay in full any amount due and
payable to AT&T pursuant to Section 6.02(d), together with interest calculated
at the Underpayment Rate from the date of the determination that there was a
Spin-Off Disqualification through the date of payment. If AT&T Broadband and
AT&T disagree as to whether an indemnity obligation is due, and the arbitration
process concludes that AT&T Broadband is liable, AT&T Broadband shall pay any
amount that would be due and payable to AT&T if AT&T were entitled to indemnity
pursuant to Section 6.02(d), together with interest on such amount calculated
at the Underpayment Rate from the date of the determination that there was a
Spin-Off Disqualification through the date of the payment. "Underpayment Rate"
shall mean the annual rate of interest described in Section 6621(c) of the Code
for large corporate underpayments of income Tax (or similar provision of state
or local income Tax law, as applicable), as determined from time to time.

     (iii) If pursuant to a final nonappealable order of a court of competent
jurisdiction, it is determined that AT&T Broadband is obligated to pay and has
not paid amounts payable to AT&T pursuant to Section 6.02(d) or that amounts
paid by AT&T Broadband to AT&T should not have been paid, AT&T Broadband shall
pay to AT&T the balance due, or AT&T shall repay to the excess amount paid, in
either event within five days of the final determination of liability or
overpayment, together with interest at the Underpayment Rate calculated (A)
from the date of the determination that there was a Spin-Off Disqualification
in the case of a payment to be made by AT&T Broadband or (B) from the date of
payment by AT&T Broadband to AT&T in the case of a repayment to be made by
AT&T. All payments pursuant to this Section 6.03(c) shall be made by wire
transfer to the bank account designated by AT&T or AT&T Broadband, as the case
may be, for such purpose.

     SECTION 6.04. Other Transactions. (a) Notwithstanding any provision of the
Tax Sharing Agreement to the contrary, AT&T Broadband shall indemnify and hold
harmless AT&T and each member of the consolidated group of which AT&T is a
member from and against one half of all Tax Related Losses imposed upon or
incurred by AT&T or any member of its group as a result of (i) the Separation
Transactions or the Split-Off failing to qualify as tax-free transactions under
the provisions of Sections 355, 361(c) and 368(a)(1)(D) of the Code, or (ii)
the shares of AWS or LMC failing to qualify as "qualified property" for
purposes of Section 355(c)(2) or 361(c) of the Code by reason of the
application of Section 355(e) of the Code (each such failure, a "Transaction
Disqualification"); provided, however, AT&T Broadband shall indemnify and hold
harmless AT&T and each member of the consolidated group of which AT&T is a
member from and against any and all Tax Related Losses imposed upon or incurred
by AT&T or any member of its group as a result of the Transaction
Disqualification if such Transaction Disqualification would not have occurred
but for an AT&T Broadband Action and; provided, further, that, AT&T Broadband
shall have no obligation to indemnify AT&T or any member of the consolidated
group of which AT&T is a member if the Transaction Disqualification would not
have occurred but for an AT&T Communications Action.

     (b) Any indemnity payment required to be made by AT&T Broadband under
Section 6.04(a) as a result of a Transaction Disqualification shall be net of
AT&T Broadband's Share of any indemnification that AT&T is entitled to receive
from AWS or LMC, as the case may be, as a result of such Transaction
Disqualification (a "Primary Indemnity Claim"). AT&T, at AT&T Broadband's
direction and expense, shall use reasonable efforts to pursue and collect AT&T
Broadband's Share of a Primary Indemnity Claim from AWS or LMC, as the case may
be, prior to seeking indemnification from AT&T Broadband for such amount. In
the event that AT&T has not received indemnification with respect to AT&T
Broadband's Share of a Primary Indemnity Claim at least five days prior to the
date on which AT&T is required to make a payment that gives rise to such claim,
AT&T shall be entitled to demand payment of AT&T Broadband's Share of a Primary
Indemnity Claim from AT&T Broadband, provided that AT&T Broadband shall have no
obligation to pay AT&T Broadband's Share of a Primary Indemnity Claim unless
AT&T has (i) provided AT&T Broadband with information in reasonable detail
describing its efforts to pursue and collect such Primary Indemnity Claim and
(ii) afforded AT&T Broadband the opportunity to take reasonable efforts on
behalf of AT&T, at AT&T Broadband's expense, to pursue and collect such Primary
Indemnity Claim. "AT&T Broadband's Share" means (i) 100% in the event the
Transaction Disqualification is attributable to an AT&T Broadband Action or
(ii) 50% otherwise. If AT&T Broadband makes payment to AT&T in respect of an
amount for which AT&T has a Primary Indemnity Claim, AT&T shall assign AT&T
Broadband's Share of such Primary Indemnity Claim to AT&T Broadband and shall
cooperate, at AT&T Broadband's direction and expense, with AT&T Broadband in
prosecuting such claim. If AT&T receives a payment required by Section 6.04(a)
from AT&T Broadband and subsequently receives a payment with respect to a
Primary Indemnity Claim that was not previously taken into account, in whole or
in part, in determining the amount of AT&T Broadband's payment to AT&T, then
AT&T will pay to AT&T Broadband an amount equal to the excess of the payment
made by AT&T Broadband over the amount of the payment that AT&T Broadband would
have been required to make if payment under the Primary Indemnity Claim had
been received by AT&T before payment was made by AT&T Broadband.

     (c) If there is a determination (as defined in Section 1313 of the Code)
that a Transaction Disqualification has occurred and the


                                      36



parties cannot agree whether such a Transaction Disqualification would not have
occurred but for an AT&T Communications Action or an AT&T Broadband Action, as
the case may be, the procedures set forth in Section 6.03(c) shall apply.

     (d) In the event that, in connection with a Transaction Disqualification
that is attributable to an AT&T Broadband Action, AT&T has any rights against
or obligations to AWS or LMC that are substantially similar to those set forth
in Section 6.03, (i) AT&T shall assign such rights and obligations to AT&T
Broadband, if at all practicable, or (ii) if such assignment cannot be achieved
for any reason, AT&T shall exercise such rights and perform such obligations at
the direction of AT&T Broadband and AT&T Broadband shall indemnify AT&T for all
associated costs. Such costs shall be reallocated and reimbursed in accordance
with the respective indemnification obligations as determined under Section
6.04(c). If a Transaction Disqualification is not attributable to an AT&T
Communications Action or an AT&T Broadband Action, such rights and obligations
shall, to the extent practicable, be exercised and performed jointly and all
associated costs shall be shared equally.

                                   ARTICLE 7

                    EXCHANGE OF INFORMATION; CONFIDENTIALITY

     SECTION 7.01. Agreement for Exchange of Information. (a) Each of AT&T and
AT&T Broadband, on behalf of the AT&T Communications Group and the AT&T
Broadband Group, respectively, agrees to provide, or cause to be provided, to
each other Group, at any time before or after the Distribution Date, as soon as
reasonably practicable after written request therefor, any Information in the
possession or under the control of such respective Group that the requesting
party reasonably needs (i) to comply with reporting, disclosure, filing or
other requirements imposed on the requesting party (including under applicable
securities or Tax laws) by a Governmental Authority having jurisdiction over
the requesting party, (ii) for use in any other judicial, regulatory,
administrative, Tax or other proceeding or in order to satisfy audit,
accounting, claims, regulatory, litigation, Tax or other similar requirements,
or (iii) to comply with its obligations under this Agreement or any other
Ancillary Agreement; provided, however, that in the event that any party
determines that any such provision of Information could be commercially
detrimental, violate any law or agreement, or waive any attorney-client
privilege, the parties shall take all reasonable measures to permit the
compliance with such obligations in a manner that avoids any such harm or
consequence. AT&T and AT&T Broadband intend that any transfer of Information
that would otherwise be within the attorney-client privilege shall not operate
as a waiver of any potentially applicable privilege.

     (b) After the date hereof, each of AT&T and AT&T Broadband shall maintain
in effect adequate systems and controls to the extent necessary to enable the
members of the other Group to satisfy their respective reporting, accounting,
audit and other obligations.

     SECTION 7.02. Ownership of Information. Any Information owned by one Group
that is provided to a requesting party pursuant to Section 7.01 shall be deemed
to remain the property of the providing party. Unless specifically set forth
herein, nothing contained in this Agreement shall be construed as granting or
conferring rights of license or otherwise in any such Information.

     SECTION 7.03. Compensation for Providing Information. The party requesting
such Information agrees to reimburse the other party for the reasonable costs,
if any, of creating, gathering and copying such Information, to the extent that
such costs are incurred for the benefit of the requesting party. Except as may
be otherwise specifically provided elsewhere in this Agreement or in any other
agreement between the parties, such costs shall be computed in accordance with
the providing party's standard methodology and procedures.

     SECTION 7.04. Record Retention. To facilitate the possible exchange of
Information pursuant to this Article 7 and other provisions of this Agreement
after the Distribution Date, the parties agree to use their reasonable best
efforts to retain all Information in their respective possession or control on
the Distribution Date in accordance with their respective record retention
policies. No party will destroy, or permit any of its Subsidiaries to destroy,
any Information that the other party may have the right to obtain pursuant to
this Agreement prior to the third anniversary of the date hereof without first
using its reasonable best efforts to notify the other party of the proposed
destruction and giving the other party the opportunity to take possession of
such information prior to such destruction; provided, however, that in the case
of any Information relating to Taxes or to Environmental Liabilities, such
period shall be extended to the expiration of the applicable statute of
limitations (giving effect to any extensions thereof). Moreover, no party will
destroy, or permit any of its Subsidiaries to destroy, any policies of
insurance (or records related to such insurance policies) without first using
its reasonable best efforts to notify the other party of the proposed
destruction and giving the other party reasonable opportunity to take
possession of such information prior to such destruction, if it is possible
that the other party may be able to obtain coverage under such policies. (The
foregoing includes "occurrence"-based liability policies, which continue to
cover liability for alleged harm during their policy period, even if no claim
is made based on such alleged harm until after the end of the policy period.)


                                      37



     SECTION 7.05. Limitation of Liability. No party shall have any liability
to any other party in the event that any Information exchanged or provided
pursuant to this Agreement that is an estimate or forecast, or that is based on
an estimate or forecast, is found to be inaccurate, in the absence of willful
misconduct by the party providing such Information. No party shall have any
liability to any other party if any Information is destroyed after reasonable
best efforts by such party to comply with the provisions of Section 7.04.

     SECTION 7.06. Other Agreements Providing for Exchange of Information. The
rights and obligations granted under this Article 7 are subject to any specific
limitations, qualifications or additional provisions on the sharing, exchange
or confidential treatment of Information set forth in any Ancillary Agreement.

     SECTION 7.07. Production of Witnesses; Records; Cooperation. (a) After the
Distribution Date, except in the case of an adversarial Action by one party
against the other party (which shall be governed by such discovery rules as may
be applicable thereto), each party hereto shall take all reasonable steps to
make available to the other party, upon written request, the former, current
and future directors, officers, employees, other personnel and agents of its
respective Group (whether as witnesses or otherwise) and any books, records or
other documents within its control or which it otherwise has the ability to
make available, to the extent that any such person (giving consideration to
business demands of such directors, officers, employees, other personnel and
agents) or books, records or other documents may reasonably be required in
connection with any Action (including preparation for such Action) in which the
requesting party may from time to time be involved, regardless of whether such
Action (or preparation for such action) is a matter with respect to which
indemnification may be sought hereunder. The requesting party shall bear all
costs and expenses (including allocated costs of in-house counsel and other
personnel) in connection therewith.

     (b) If an Indemnifying Party chooses to defend or to seek to compromise or
settle any Third Party Claim, or if any party chooses or is required to
prosecute, pursue, otherwise evaluate or defend any Action, the other parties
shall cooperate in such defense, settlement or compromise, or such prosecution,
evaluation or pursuit, as the case may be.

     (c) Without limiting the foregoing, the parties shall cooperate and
consult to the extent reasonably necessary with respect to any Actions.

     (d) Without limiting any provision of this Section 7.07, each of the
parties agrees to cooperate, and to cause each member of its respective Group
to cooperate, with each other in the defense of any infringement or similar
claim with respect to any intellectual property and shall not claim to
acknowledge, or permit any member of its respective Group to claim to
acknowledge, the validity or infringing use of any intellectual property of a
third Person in a manner that would hamper or undermine the defense of such
infringement or similar claim.

     (e) The obligation of the parties to make available former, current and
future directors, officers, employees, other personnel and agents pursuant to
this Section 7.07 is intended to be interpreted in a manner so as to facilitate
cooperation and shall include the obligation to make available inventors and
other officers without regard to whether such individual or the employer of
such individual could assert a possible business conflict (subject to the
exception set forth in the first sentence of Section 7.07(a)). Without limiting
the foregoing, each party agrees that (i) neither it nor any member of its
respective Group will take adverse action against any employee of its Group
based on such employee's provision of assistance or information to the other
party pursuant to Section 7.07(a) and (ii) to the extent relevant and
necessary, neither it nor any member of its respective Group will enforce any
confidentiality agreement against an employee of its Group that would otherwise
prevent or hinder such employee from cooperating or providing information to a
requesting party pursuant to Section 7.07(a).

     (f) In connection with any matter contemplated by this Section 7.07, the
parties will enter into a mutually acceptable joint defense agreement so as to
maintain to the extent practicable any applicable attorney-client privilege or
work product immunity of either Group.

     SECTION 7.08. Confidentiality. (a) Subject to Section 7.09, each of AT&T
and AT&T Broadband, on behalf of itself and its respective Group, agrees to
hold, and to cause its respective directors, officers, employees, agents,
accountants, counsel and other advisors and representatives to hold, in strict
confidence, with at least the same degree of care that applies to its own
confidential and proprietary information pursuant to policies in effect at the
relevant time, all Information concerning the other Group that is either in its
possession (including Information in its possession prior to any of the date
hereof, or the Distribution Date) or furnished by the other Group or its
respective directors, officers, employees, agents, accountants, counsel and
other advisors and representatives at any time pursuant to this Agreement, any
other Ancillary Agreement or otherwise, and shall not use any such Information
other than for such purposes as shall be expressly permitted hereunder or
thereunder, except, in each case, to the extent that such Information has


                                      38



been (i) in the public domain through no fault of such party or such party's
Group or any of their respective directors, officers, employees, agents,
accountants, counsel and other advisors and representatives, (ii) later
lawfully acquired from other sources by such party (or such party's Group),
which sources are not themselves bound by a confidentiality obligation, or
(iii) independently generated without reference to any proprietary or
confidential Information of the other party.

     (b) Each party agrees not to release or disclose, or permit to be released
or disclosed, any such Information concerning the other Group to any other
Person, except its directors, officers, employees, agents, accountants, counsel
and other advisors and representatives who need to know such Information (who
shall be advised of their obligations hereunder with respect to such
Information), except in compliance with Section 7.09. Without limiting the
foregoing, when any Information is no longer needed for the purposes
contemplated by this Agreement or any other Ancillary Agreement, each party
will promptly after request of the other party either return to the other party
all Information in a tangible form (including all copies thereof and all notes,
extracts or summaries based thereon) or certify to the other party that it has
destroyed such Information (and such copies thereof and such notes, extracts or
summaries based thereon).

     SECTION 7.09. Protective Arrangements. In the event that any party or any
of its Subsidiaries either determines on the advice of its counsel that it is
required to disclose any Information concerning the other Group pursuant to
applicable law or receives any demand under lawful process or from any
Governmental Authority to disclose or provide Information concerning the other
Group that is subject to the confidentiality provisions hereof, such party
shall notify the other party of such disclosure at least five days prior to
disclosing or providing such Information and shall cooperate at the expense of
the requesting party in seeking any reasonable protective arrangements
requested by such other party. Subject to the foregoing, after a court of
competent jurisdiction has had an opportunity to rule on such protective
arrangements, the Person that received such request may thereafter disclose or
provide Information to the extent required by such law (as so advised by
counsel) or by lawful process or such Governmental Authority.

                                   ARTICLE 8

                  FURTHER ASSURANCES AND ADDITIONAL COVENANTS

     SECTION 8.01. Further Assurances. (a) In addition to the actions
specifically provided for elsewhere in this Agreement, the other Ancillary
Agreements and the Merger Agreement, but subject to the provisions hereof and
thereof, each of the parties hereto shall use its reasonable best efforts,
prior to, on and after the Distribution Date, to take, or cause to be taken,
all actions, and to do, or cause to be done, all things, reasonably necessary,
proper or advisable under applicable laws, regulations and agreements to
consummate and make effective the transactions contemplated by this Agreement,
the other Ancillary Agreements and the Merger Agreement.

     (b) Without limiting the foregoing, prior to, on and after the
Distribution Date, each party hereto shall cooperate with the other party, and
without any further consideration, to execute and deliver, or use its
reasonable best efforts to cause to be executed and delivered, all instruments,
including instruments of conveyance, assignment and transfer, and to make all
filings with, and to obtain all consents, approvals or authorizations of, any
Governmental Authority or any other Person under any permit, license,
agreement, indenture or other instrument (including any Consents or
Governmental Approvals), and to take all such other actions as such party may
reasonably be requested to take by any other party hereto from time to time,
consistent with the terms of this Agreement, the other Ancillary Agreements and
the Merger Agreement, in order to effectuate the provisions and purposes of
this Agreement, the other Ancillary Agreements and the Merger Agreement and the
transfers of the AT&T Broadband Assets and the assignment and assumption of the
AT&T Broadband Liabilities and the other transactions contemplated hereby and
thereby.

     (c) On or prior to the Distribution Date, AT&T and AT&T Broadband in their
respective capacities as direct and indirect shareholders of their respective
Subsidiaries, shall each ratify any actions that are reasonably necessary or
desirable to be taken by AT&T and AT&T Broadband or any other Subsidiary of
AT&T, as the case may be, to effectuate the transactions contemplated by this
Agreement.

                                   ARTICLE 9

                                  TERMINATION

     SECTION 9.01. Termination. This Agreement may be terminated by AT&T prior
to the Distribution Date at any time following termination of the Merger
Agreement in accordance with its terms.


                                      39



     SECTION 9.02. Effect of Termination. In the event of any termination of
this Agreement prior to the Distribution Date, no party to this Agreement (or
any of its directors or officers) shall have any Liability or further
obligation to any other party with respect to this Agreement.

                                   ARTICLE 10

                       DISPUTE RESOLUTION AND ARBITRATION

     SECTION 10.01. Agreement to Arbitrate. Except as otherwise specifically
provided in this Agreement (including, without limitation, in Article 6,
concerning Third Party Tax Claims) or in any other Ancillary Agreement, the
procedures set forth in this Article 10 shall apply to all disputes,
controversies or claims (whether sounding in contract, tort or otherwise) that
may arise out of or relate to, or arise under or in connection with this
Agreement or any other Ancillary Agreement, or the transactions contemplated
hereby or thereby (including all actions taken in furtherance of the
transactions contemplated hereby or thereby on or prior to the date hereof), or
the commercial or economic relationship of the parties relating hereto or
thereto, between or among any member of the AT&T Broadband Group, or the AT&T
Communications Group. Each party agrees on behalf of itself and each member of
its respective Group that the procedures set forth in this Article 10 shall be
the sole and exclusive remedy in connection with any dispute, controversy or
claim relating to any of the foregoing matters and irrevocably waives any right
to commence any Action in or before any Governmental Authority, except as
expressly provided in Sections 10.11(c) and 10.12 and except to the extent
provided under the Federal Arbitration Act in the case of judicial review of
arbitration results or awards. Each party on behalf of itself and each member
of its respective Group irrevocably waives any right to any trial by jury with
respect to any claim, controversy or dispute set forth in the first sentence of
this Section 10.01. The parties agree that claims filed pursuant to this
Article 10 may seek direct damages but in no event for such claims shall either
party be liable to the other for any incidental, special, reliance,
consequential or any other indirect damages or losses (including lost profits
or revenues).

     SECTION 10.02. Reasonable Best Efforts to Resolve Disputes; Mediation. It
is the intent of the parties to use their respective reasonable best efforts to
negotiate and resolve expeditiously any dispute, controversy or claim between
or among them that may arise from time to time on a mutually acceptable
negotiated basis. The parties may, by mutual consent, retain a mediator to aid
in any attempt to informally negotiate resolution of any dispute, although any
opinion expressed by a mediator shall be strictly advisory and shall not be
binding on the parties, nor shall any opinion expressed by the mediator be
admissible in any arbitration proceedings. Costs of a mediation shall be borne
equally by the parties involved in the matter, except that each party shall be
responsible for its own expenses. Mediation is not a prerequisite to a demand
for arbitration under Section 10.03.

     SECTION 10.03. Demand for Arbitration. At any time before the Applicable
Deadline, any party involved in the dispute, controversy or claim may make a
written demand (the "Arbitration Demand Notice") that the dispute be resolved
by binding arbitration, which Arbitration Demand Notice shall be given to the
parties to the dispute, controversy or claim in the manner set forth in Section
11.08. Such Arbitration Demand Notice shall describe in reasonable detail the
facts surrounding such dispute, controversy or claim and the basis of such
party's claim for relief pursuant to this Article. Except as may be expressly
provided in any Ancillary Agreement, any Arbitration Demand Notice must be
asserted within one year after the later of the occurrence of the act or event
giving rise to the underlying claim or the date on which such act or event was,
or should have been, in the exercise of reasonable due diligence, discovered by
the party asserting the claim (as applicable and as it may in a particular case
be specifically extended by the parties in writing, the "Applicable Deadline";
provided that in no event will the Applicable Deadline occur with respect to
any matter before the first anniversary of the Distribution). Any discussions,
negotiations or mediations between the parties pursuant to this Agreement or
otherwise will not toll the Applicable Deadline unless expressly agreed in
writing by the parties. Each of the parties agrees on behalf of itself and each
member of its Group that if an Arbitration Demand Notice with respect to a
dispute, controversy or claim is not given prior to the expiration of the
Applicable Deadline, as between or among the parties and the members of their
Groups, such dispute, controversy or claim will be barred. Subject to Sections
10.11(c) and 10.12, upon delivery of an Arbitration Demand Notice prior to the
Applicable Deadline, the dispute, controversy or claim shall be decided by an
Arbitration Panel in accordance with the rules set forth in this Article 10.

     SECTION 10.04. Arbitration Panel. When an Arbitration Demand Notice is
given, the parties involved in the dispute, controversy or claim shall attempt
to select a sole arbitrator satisfactory to all such parties. In the event the
parties are not able jointly to select a sole arbitrator, such parties shall
each appoint an arbitrator within 30 days after delivery of the Arbitration
Demand Notice. Only one arbitrator may be appointed for the AT&T Broadband
Group and the AT&T Communications Group, respectively. In the event that a sole
arbitrator is not selected, the two chosen arbitrators, within 30 days after
the appointment of the later of them to be appointed, will in turn choose a
third arbitrator, and the three arbitrators thus chosen will constitute the
arbitration panel.


                                      40



     SECTION 10.05. Commencement and Place of Arbitration. The sole arbitrator
or arbitration panel (as applicable, the "Arbitration Panel") will meet within
30 days of the last appointment to commence the arbitration, which period may
be extended upon the agreement of the arbitrators. The Arbitration Panel will
set a time for the hearing of the matter, which will commence no later than 90
days after the date of the last appointment. The place of any arbitration
hereunder will be as agreed upon by the parties, or, if the parties are unable
to agree, as set by the Arbitration Panel.

     SECTION 10.06. Arbitration Hearings. The matter shall be presented to the
Arbitration Panel at a hearing by means of written submissions of memoranda and
verified witness statements, filed simultaneously, and responses, if necessary
in the judgment of the arbitrator or both the parties. If the Arbitration Panel
deems it to be appropriate for a fair resolution of the dispute, live
cross-examination or direct examination may be permitted. The Arbitration Panel
shall actively manage the arbitration with a view to achieving a just, speedy
and cost-effective resolution of the dispute, claim or controversy. The
arbitration hearing will be no longer than 30 full hearing days, unless in the
judgment of the Arbitration Panel the matter is complex and sophisticated and
thereby requires a longer time; provided, however, that such hearing shall in
any event be completed within 180 calendar days. The Arbitration Panel may set
time and other limits on the presentation of each party's case, its memoranda
or other submissions, and may refuse to receive any proffered evidence, that
the Arbitration Panel finds to be cumulative, unnecessary, irrelevant or of low
probative nature. Except as otherwise set forth herein, any arbitration
hereunder will be conducted in accordance with the CPR Rules for
Non-Administered Arbitration of Business Disputes then prevailing (except that
the arbitration will not be conducted under the auspices of the CPR and the fee
schedule of the CPR will not apply). To the extent that the provisions of this
Agreement and the prevailing rules of the CPR conflict, the provisions of this
Agreement shall govern.

     SECTION 10.07. Arbitration Decision. The final decision of the Arbitration
Panel will be rendered in writing to the parties not later than 60 days after
the last hearing date, unless otherwise agreed by the parties in writing. The
decision of the Arbitration Panel will be final and binding on the parties, and
judgment thereon may be had and will be enforceable in any court having
jurisdiction over the parties. Arbitration awards will bear interest at an
annual rate of the Prime Rate plus 2% per annum.

     SECTION 10.08. Discovery and Related Matters. Any party involved in the
applicable dispute may request limited document production from the other party
or parties of specific and expressly relevant documents. Any such discovery
shall be conducted expeditiously, and it is intended that discovery shall be
limited as compared to the provisions of the Federal Rules of Civil Procedure.
Depositions shall not occur except by consent of the parties or by order of the
Arbitration Panel. Disputes concerning the document production or other
discovery will be determined by written agreement of the parties involved in
the applicable dispute or, failing such agreement, will be referred to the
Arbitration Panel for resolution. All discovery requests will be subject to the
proprietary rights and rights of privilege of the parties, and the Arbitration
Panel will adopt procedures to protect such rights and to maintain the
confidential treatment of the arbitration proceedings (except as may be
required by law). Subject to the foregoing, the Arbitration Panel shall have
the power to issue subpoenas to compel the production of documents relevant to
the dispute, controversy or claim.

     SECTION 10.09. Arbitration Panel's Authority. The Arbitration Panel shall
have full power and authority to determine issues of arbitrability and to
interpret or construe the applicable provisions of this Agreement or any other
Ancillary Agreement and to fashion appropriate remedies for breaches of this
Agreement (including interim or permanent injunctive relief); provided that the
Arbitration Panel shall not have any right or authority (i) in excess of the
authority a court having jurisdiction over the parties and the controversy or
dispute would have absent these arbitration provisions; (ii) to award
incidental, special, reliance, consequential, or other indirect damages
(including lost profits or revenues); (iii) to award punitive or treble
damages; or (iv) to modify the terms of this Agreement. It is the intention of
the parties that in rendering a decision, the Arbitration Panel give effect to
the applicable provisions of this Agreement and the other Ancillary Agreements
and follow applicable law (it being understood and agreed that this sentence
shall not give rise to a right of judicial review of the arbitrator's award).

     SECTION 10.10. Confidentiality. Except as required by law, the parties
agree that the existence and contents of the entire arbitration, including the
award, shall be deemed a compromise of a dispute under Rule 408 of the Federal
Rules of Evidence, shall not be discoverable in any proceeding, shall not be
admissible in any court (except for the enforcement thereof) or arbitration and
shall not bind or collaterally estop either party with respect to any claim or
defense asserted by any third party. Except as required by law, the parties
shall hold, and shall cause their respective officers, directors, employees,
agents and other representatives to hold, the existence, content and result of
the arbitration or any mediation in confidence in accordance with the
provisions of Article 7 and except as may be required in order to enforce any
award. Each of the parties shall request that any mediator or arbitrator comply
with such confidentiality requirement.

     SECTION 10.11. Certain Additional Matters. (a) If a party fails or refuses
to appear at and participate in an arbitration hearing after due notice, the
arbitrator may hear and determine the controversy upon evidence produced by the
appearing party.


                                      41



     (b) Arbitration costs will be borne equally by each party involved in the
matter, except that each party will be responsible for its own attorneys' fees
and other costs and expenses, including the costs of witnesses selected by such
party.

     (c) Prior to the time at which the Arbitration Panel are appointed, any
party may seek one or more temporary restraining orders in a court of competent
jurisdiction if necessary in order to preserve and protect the status quo.
Neither the request for, or grant or denial of, any such temporary restraining
order shall be deemed a waiver of the obligation to arbitrate as set forth
herein and the Arbitration Panel may dissolve, continue or modify any such
order.

     (d) In the event that at any time any member of the Arbitration Panel
shall fail to serve as an arbitrator for any reason, the appropriate party or
the two party-selected arbitrators, as the case may be, shall select a new
arbitrator, in accordance with the procedures set forth in Section 10.04. The
extent, if any, to which testimony previously given shall be repeated or may be
relied upon based on the stenographic record (if there is one), shall be
determined by the replacement arbitrator.

     SECTION 10.12. Limited Court Actions. (a) Notwithstanding anything herein
to the contrary, in the event that any party reasonably determines the amount
in controversy in any dispute, controversy or claim (or any series of related
disputes, controversies or claims) under this Agreement or any other Ancillary
Agreement is, or is reasonably likely to be, in excess of $100 million and if
such party desires to commence an Action in lieu of complying with the
arbitration provisions of this Article 10, such party shall so state in its
Arbitration Demand Notice. If the other parties to the arbitration disagree
about whether the amount in controversy exceeds $100 million, the Arbitration
Panel selected pursuant to Section 10.04 shall decide the issue. The
Arbitration Panel shall set a date no later than ten days after the date of its
appointment for submissions by the parties with respect to such issue. There
shall be no discovery in connection with such issue. The Arbitration Panel
shall render its decision on such issue within five days of such date so set by
the Arbitration Panel. The parties agree that any statute of limitations
applicable to the dispute, controversy or claim before the Arbitration Panel
shall be tolled during the pendency of the decision described in the
immediately preceding sentence. In the event that the Arbitration Panel
determines that the amount in controversy is or is reasonably likely to be in
excess of $100 million, the provisions of Sections 10.05, 10.06, 10.07, 10.08,
and 10.14 shall not apply, and within 15 days of such decision, any party to
the arbitration may elect in lieu of arbitration, to commence an Action with
respect to such dispute, controversy or claim (or such series of related
disputes, controversies or claims) in any court of competent jurisdiction
returned to in Section 11.03. If the Arbitration Panel does determines that the
amount in controversy is not in excess of $100 million, the provisions of this
Article 10 (including with respect to time periods) shall apply as if no
determinations were sought or made pursuant to this Section 10.12(a).

     (b) In the event that an arbitration award in excess of $100 million is
issued in any arbitration proceeding commenced hereunder, any party may, within
60 days after the date of such award, submit the dispute, controversy or claim
(or series of related disputes, controversies or claims) giving rise thereto to
a court of competent jurisdiction, regardless of whether such party or any
other party sought to commence an Action in lieu of proceeding with arbitration
in accordance with Section 10.12(a). In such event, the applicable court may
elect to rely on the record developed in the arbitration or, if it determines
that it would be advisable in connection with the matter, allow the parties to
seek additional discovery or to present additional evidence. Each party shall
be entitled to present arguments to the court with respect to whether any such
additional discovery or evidence shall be permitted and with respect to all
other matters relating to the applicable dispute, controversy or claim (or
series of related disputes, controversies or claims).

     SECTION 10.13. Continuity of Performance and Remaining Obligations. Unless
otherwise agreed in writing, the parties will continue to provide service and
honor all other commitments under this Agreement and each other Ancillary
Agreement during the course of dispute resolution pursuant to the provisions of
this Article 10 with respect to all matters not subject to such dispute,
controversy or claim.

     SECTION 10.14. Law Governing Arbitration Procedures. The interpretation of
the provisions of this Article 10, only insofar as they relate to the agreement
to arbitrate and any procedures pursuant thereto, shall be governed by the
Federal Arbitration Act and other applicable federal law. In all other
respects, the interpretation of this Agreement shall be governed as set forth
in Section 11.02.

     SECTION 10.15. Non-applicability of Article. Notwithstanding anything
herein to the contrary, this Article 10 shall not apply to any dispute,
controversy or claim or to any other matter whatsoever arising under Section
6.02 or 6.03, the Tax Sharing Agreement, any other Tax sharing agreement or any
Third Party Tax Claims or to any other matter relating to Taxes. This Article
similarly shall not apply to the extent provided in any other Ancillary
Agreement.


                                      42



                                   ARTICLE 11
                                 MISCELLANEOUS

     SECTION 11.01. Counterparts; Entire Agreement; Corporate Power. (a) This
Agreement and each other Ancillary Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party.

     (b) This Agreement, and the other Ancillary Agreements and the Exhibits,
Schedules and Appendices hereto and thereto contain the entire agreement
between the parties with respect to the subject matter hereof or thereof,
supersede all previous agreements, negotiations, discussions, writings,
understandings, commitments and conversations with respect to such subject
matter and there are no agreements or understandings between the parties other
than those set forth or referred to herein or therein.

     (c) AT&T represents on behalf of itself and each of its Subsidiaries
(other than the AT&T Broadband Entities) and AT&T Broadband represents on
behalf of itself and each other AT&T Broadband Entity:

          (i) each such Person is a corporation or other entity duly
     incorporated or formed, validly existing and in good standing under the
     laws of the state of its incorporation or formation, has all corporate or
     other similar powers required to carry on its business as currently
     conducted and is duly qualified to do business and is in good standing in
     each jurisdiction where such qualification is necessary, except for those
     jurisdictions where failure to be so qualified, individually or in the
     aggregate, has not had and would not reasonably be expected to have an
     AT&T Material Adverse Effect or an AT&T Broadband Material Adverse Effect,
     respectively;

          (ii) each such Person has the requisite corporate or other power and
     authority and has taken all corporate or other similar action necessary in
     order to execute, deliver and perform each of this Agreement and each
     other Ancillary Agreements to which it is a party and to consummate the
     transactions contemplated hereby and thereby; and

          (iii) this Agreement and each other Ancillary Agreement to which any
     such Person is a party has been duly executed and delivered by such Person
     and constitutes a valid and binding agreement of such Person enforceable
     in accordance with the terms thereof.

     (d) Each party hereto acknowledges that it and each other party hereto is
executing certain of the Ancillary Agreements by facsimile, stamp or mechanical
signature. Each party hereto expressly adopts and confirms each such facsimile,
stamp or mechanical signature made in its respective name as if it were a
manual signature, agrees that it will not assert that any such signature is not
adequate to bind such party to the same extent as if it were signed manually
and agrees that at the reasonable request of any other party hereto at any time
it will as promptly as reasonably practicable cause each such Ancillary
Agreement to be manually executed (any such execution to be as of the date of
the initial date thereof).

     SECTION 11.02. Governing Law. This Agreement and, unless expressly
provided therein, each other Ancillary Agreement, shall be governed by and
construed and interpreted in accordance with the laws of the State of New York,
irrespective of the choice of laws principles of the State of New York, as to
all matters, including matters of validity, construction, effect,
enforceability, performance and remedies.

     SECTION 11.03. Jurisdiction. Except as otherwise expressly provided in
this Agreement, the parties hereto agree that any suit, action or proceeding
seeking to enforce any provision of, or based on any matter arising out of or
in connection with, this Agreement, any of the other Ancillary Agreements or
the transactions contemplated hereby or thereby shall be brought in the United
States District Court for the Southern District of New York or any New York
State court sitting in New York City, so long as one of such courts shall have
subject matter jurisdiction over such suit, action or proceeding, and that any
cause of action arising out of this Agreement or out of any of the other
Ancillary Agreements shall be deemed to have arisen from a transaction of
business in the State of New York, and each of the parties hereby irrevocably
consents to the jurisdiction of such courts (and of the appropriate appellate
courts therefrom) in any such suit, action or proceeding and irrevocably
waives, to the fullest extent permitted by law, any objection that it may now
or hereafter have to the laying of the venue of any such suit, action or
proceeding in any such court or that any such suit, action or proceeding which
is brought in any such court has been brought in an inconvenient forum. Process
in any such suit, action or proceeding may be served on any party anywhere in
the world, whether within or without the jurisdiction of any such court.
Without limiting the foregoing, each party agrees that service of process on
such party as provided in Section 11.06 shall be deemed effective service of
process on such party.


                                      43



     SECTION 11.04. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT, ANY OF THE OTHER ANCILLARY
AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     SECTION 11.05. Assignability. Except as set forth in any Ancillary
Agreement, this Agreement and each other Ancillary Agreement shall be binding
upon and inure to the benefit of the parties hereto and thereto, respectively,
and their respective successors and assigns; provided, however, that no party
hereto or thereto may assign its respective rights or delegate its respective
obligations under this Agreement or any other Ancillary Agreement without the
express prior written consent of each of the other parties hereto or thereto.

     SECTION 11.06. AT&T Restructuring. AT&T and AT&T Broadband recognize that
AT&T is contemplating creating a tracking stock with respect to its consumer
services business. Subject to AT&T's obligations under the Merger Agreement,
including Section 9.06(b) thereof, nothing in this Agreement shall prevent the
creation by AT&T of any tracking stock with respect to such business or
otherwise. In the event of the creation of such a tracking stock, (i)
references in this Agreement to AT&T Common Stock shall be adjusted as
necessary to accommodate the existence of such tracking stock and (ii) AT&T
may, but is not required to, distribute all or a portion of the shares of such
tracking stock in the Distribution. In the event any such tracking stock is
distributed in connection with the Distribution, Article 4 shall be revised to
appropriately account for such distribution. Any adjustment or revision
pursuant to the preceding sentence shall be reasonably satisfactory to Comcast.

     SECTION 11.07. Third Party Beneficiaries. Except for Comcast, which prior
to any termination of this Agreement shall be a third party beneficiary of AT&T
Broadband's rights under to this Agreement and each other Ancillary Agreement,
and except for the indemnification rights under this Agreement of any AT&T
Indemnitee or AT&T Broadband Indemnitee in their respective capacities as such,
and except as specifically provided in the Employee Benefits Agreement, (i) the
provisions of this Agreement and each other Ancillary Agreement are solely for
the benefit of the parties and are not intended to confer upon any Person
except the parties any rights or remedies hereunder, and (ii) there are no
third party beneficiaries of this Agreement or any other Ancillary Agreement
and neither this Agreement nor any other Ancillary Agreement shall provide any
third person with any remedy, claim, liability, reimbursement, claim of action
or other right in excess of those existing without reference to this Agreement
or any other Ancillary Agreement.

     SECTION 11.08. Notices. All notices or other communications under this
Agreement or any other Ancillary Agreement shall be in writing and shall be

notices are to be given.

     SECTION 11.09. Severability. If any provision of this Agreement or any
other Ancillary Agreement or the application thereof to any Person or
circumstance is determined by a court of competent jurisdiction to be invalid,
void or unenforceable, the remaining provisions hereof or thereof, or the
application of such provision to Persons or circumstances or in jurisdictions
other than those as to which it has been held invalid or unenforceable, shall
remain in full force and effect and shall in no way be affected, impaired or
invalidated thereby, so long as the economic or legal substance of the
transactions contemplated hereby or thereby, as the case may be, is not
affected in any manner adverse to any party. Upon such determination, the
parties shall negotiate in good faith in an effort to agree upon such a
suitable and equitable provision to effect the original intent of the parties.

     SECTION 11.10. Expenses. The provisions of Sections 11.03(a)-(c) of the
Merger Agreement are hereby incorporated by reference.

     SECTION 11.11. Headings. The Article, Section and paragraph headings
contained in this Agreement and in the other Ancillary Agreements are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement or any other Ancillary Agreement.

     SECTION 11.12. Waivers of Default. Waiver by any party of any default by
the other party of any provision of this Agreement or any other Ancillary
Agreement shall not be deemed a waiver by the waiving party of any subsequent
or other default, nor shall it prejudice the rights of the other party.

     SECTION 11.13. Specific Performance. In the event of any actual or
threatened default in, or breach of, any of the terms, conditions and
provisions of this Agreement or any other Ancillary Agreement, the party or
parties who are or are to be thereby aggrieved shall have the right to specific
performance and injunctive or other equitable relief of its rights under this
Agreement or such other Ancillary Agreement, in addition to any and all other
rights and remedies at law or in equity, and all such rights and remedies shall
be cumulative. The parties agree that the remedies at law for any breach or
threatened breach, including monetary damages, are inadequate compensation for
any loss and that any defense in any action for specific performance that a
remedy at law would be adequate is waived. Any requirements for the securing or
posting of any bond with such remedy are waived.

     SECTION 11.14. Amendments. No provisions of this Agreement or any other
Ancillary Agreement shall be deemed waived, amended, supplemented or modified
by any party, unless such waiver, amendment, supplement or modification is in
writing and signed by the authorized representative of the party against whom
such waiver, amendment, supplement or modification it is sought to be enforced.

     SECTION 11.15. Late Payments. Except as expressly provided to the contrary
in this Agreement or in any other Ancillary Agreement, any amount not paid when
due pursuant to this Agreement or any other Ancillary Agreement (and any
amounts billed or


                                      45



otherwise invoiced or demanded and properly payable that are not paid within 30
days of such bill, invoice or other demand) shall accrue interest at a rate per
annum equal to the Prime Rate plus 2%.

     SECTION 11.16. Interpretation. Words in the singular shall be held to

     The following provisions set forth the parties' understandings with
respect to the disposition of all or any portion of the interest in TWE (the
"TWE Interest") held, as of the date hereof, by MediaOne TWE Holdings, Inc. and
its affiliates at any time or from time to time whether prior to or after the
Closing Date:

     (a) The following terms, as used in this Annex I, have the following
meanings:

     "Closing Date" has the meaning set forth in the Merger Agreement.

     "Contingent Payment" means (i) 50% of the excess, if any, of (A) the
Determined Value over (B) the Threshold Amount, reduced by (ii) an amount equal
to the product of 50% of such excess and the rate set forth in subparagraph (e)
hereof.

     "Determined Value" means the Fair Market Value of the TWE Interest or
portion thereof disposed of, as the case may be; provided, however, that if all
or any portion of the TWE Interest is disposed of within the TWE Disposition
Period under Article XIII of the TWE Partnership Agreement or pursuant to one
or more negotiated dispositions or public or private market dispositions, then
the Determined Value with respect to such portion shall be the Proceeds from
such disposition(s).

     "Fair Market Value" means with respect to all or any portion of the TWE
Interest, the Proceeds that would be received in a public offering of such
interest (or corresponding equity securities of a corporation into which TWE is
converted or that holds the TWE interest) (after deducting (i) reasonable
expenses, including underwriters' discounts and commissions and (ii) in the
event such offering is an initial public offering, an appropriate initial
public offering discount) based on the then prevailing market conditions.

     "Parent" has the meaning set forth in the Merger Agreement.

     "Proceeds" means (subject to clause (d) below) (a) if the proceeds are
paid in cash, the amount of the cash actually received;

     (b) if the proceeds are paid in securities, assets or rights:

          (i) in the case of securities, assets or rights listed on any
     established stock exchange or a national market system including the
     National Market System of the National Association of Securities Dealers,
     Inc. Automated Quotation ("NASDAQ") System, Proceeds means the average of
     the closing sales price for such item (or the closing bid, if no sales
     were reported) reported in the Wall Street Journal for the 20 consecutive
     trading day period prior to such date;

          (ii) in the case of securities, assets or rights quoted on the NASDAQ
     System (but not on the National Market System thereof) or regularly quoted
     by a recognized securities dealer but selling prices are not reported,
     Proceeds means the average of the means between the high and low asked
     prices for the item for the 20 consecutive trading day period prior to
     such date; or

          (iii) in the absence of an established market for the securities,
     assets or rights (including the rights embodied in this Annex I), Proceeds
     means the fair value thereof as determined in good faith by a mutually
     acceptable investment banking firm.

     "Threshold Amount" means at any given time, an amount, which will
initially be $10.2 billion and shall be reduced by the aggregate Proceeds of
previous dispositions of the TWE Interest received from time to time, provided
that from the date the Merger Agreement is entered into, the outstanding
balance of the Threshold Amount from time to time shall bear simple interest at
a rate of 7% per annum and such interest shall be added to the Threshold
Amount.

     "TWE Disposition Period" has the meaning set forth in clause (b) of this
Annex I.

     (b) If all or any part of the TWE Interest is disposed of by AT&T
Broadband, Parent or their respective successors during the period beginning on
the date the Merger Agreement is signed and ending on the last day of the 54th
month after the Closing Date (the "TWE Disposition Period"), and the Closing
occurs, AT&T Broadband shall pay to AT&T on behalf of the AT&T Communications
Group, an amount equal to the Contingent Payment. Any Contingent Payment shall
be paid in the same proportion of cash, securities, assets and rights as was
received in the disposition and no Contingent Payment shall be made until
amounts equal to the Threshold Amount have been received as Proceeds. For the
avoidance of doubt, the transactions contemplated by the Merger Agreement and
this


                                      48



Agreement shall not be considered a disposition for purposes hereof.

     (c) If the TWE Interest has not been fully disposed of within the TWE
Disposition Period, the remaining interest shall be appraised by a mutually
acceptable investment banking firm on the basis of Fair Market Value. To the
extent that the Proceeds that would be received if such remaining interest were
disposed of for Fair Market Value exceeds the Threshold Amount, AT&T Broadband
shall pay to AT&T on behalf of the AT&T Communications Group an amount in cash
equal to 50% of such excess, reduced by an amount equal to the product at 50%
of such excess and the tax rate set forth in subparagraph (e) hereof, and AT&T
Broadband shall have no further obligations under this Annex I. If no payment
is required to be made pursuant to the preceding sentence, AT&T Broadband shall
have no further obligations under this Annex I.

     (d) In the event that, before the Closing Date, AT&T (subject to Section
8.01(xii) of the Merger Agreement), or after the Closing Date, Parent, effects
a disposition of the TWE Interest on a Tax deferred basis, the payment to be
made to AT&T (taking into account the present value of the deferred Tax, the
direct and indirect costs of executing the transaction (including the detriment
of any guarantees required to be given) and the risk of the transaction) shall
be determined in good faith by the Board of Directors of AT&T Broadband or
Parent, as applicable.

     (e) For purposes of this Annex I, the Tax rate will be assumed to be the
highest combined federal, state and local marginal corporate Tax rate in effect
at the relevant time.

     (f) For all Tax purposes (unless required by a change in applicable Tax
law or resolution of a contest conducted in good faith and not settled,
compromised and/or conceded without the other party's consent, which shall not
be unreasonably withheld), the parties hereto agree to treat, and to cause
their respective affiliates to treat any payment hereunder as a distribution by
AT&T Broadband to AT&T, as the case may be, occurring immediately prior to the
Distribution and in connection with the Distribution.

Trust shall have legal and record ownership of the MOC TWE Interest and all
other assets constituting Disposition Property (as defined in Section 4).

           (c) Grantor represents and warrants to the Operating Trustee that:
(i) the MOC TWE Contribution was effected in accordance with applicable FCC
Regulations; (ii) as of the Contribution Date, Grantor had full right and legal
authority to effect the MOC TWE Contribution as described herein; (iii) as of
the Contribution Date, the MOC TWE Interest was not subject to any liens or
other encumbrances (other than as created by, or permitted under, this
Agreement, the TWE Restructuring Documents or the TWE Partnership Agreement);
and (iv) all consents, waivers and approvals of the Federal Communications
Commission ("FCC") and third parties necessary for the MOC TWE Contribution
have been received and are in full force and effect.

           (d) If any additional interest in TWE is acquired by AT&T Comcast or
any of its subsidiaries during the Trust Term, AT&T Comcast shall cause such
interest to be contributed to the Trust and become property of the Trust or, if
AT&T Comcast so elects, AT&T Comcast may cause such additional interest to be
contributed to, and become property of, Trust III or (following its formation)
Trust II. Except as provided herein, no other property may be


                                      -8-



contributed to the Trust by any party without the prior written agreement of
the Operating Trustee.

      3. Term of the Trust and Irrevocability. The Trust shall be irrevocable
by Grantor and shall have a term that expires at such time as the Trust
terminates in accordance with the provisions of Section 13 (the "Trust Term").

      4. Operating Trustee Control of the Disposition Property. The Operating
Trustee shall have sole and exclusive authority to manage: (a) the MOC TWE
Interest; (b) any additional TWE interest subsequently contributed to the
Trust; (c) any Restricted Consideration (as defined in Section 5(c)) received
by the Trust; and (d) any other non-cash consideration received by the Trust in
an Alternate Disposition (as defined in Section 5(c)) or as a dividend or
distribution on securities or ownership interests held by the Trust and not
approved by the Media Bureau (as defined in Section 5(e)) for distribution to
Grantor in accordance with Section 5(e) or 6(b), respectively, (such TWE
interests, Restricted Consideration and other non-cash assets received by the
Trust and not approved for distribution, collectively, the "Disposition
Property"), and to exercise any and all rights with respect to any Disposition
Property including, without limitation, the MOC Assumed Rights and the right to
exercise any voting, director appointment, consent, approval or management
rights arising from the Disposition Property under the TWE Partnership
Agreement, in a manner intended to maximize the value of the Disposition
Property. Without limiting the foregoing, Grantor or its affiliates will, upon
or prior to the Closing, cause the representatives appointed by Grantor (or any
of its affiliates) to the TWE board of representatives to resign and,
subsequent to such resignations, the Operating Trustee will exercise any right
to appoint replacement representatives when, in the Operating Trustee's
judgment, doing so is necessary to protect the value of any Disposition
Property.


                                      -9-



Grantor shall not retain any voting, director appointment, consent, approval or
management rights with respect to the Disposition Property. Grantor shall not
have any rights to require the Operating Trustee to consult with Grantor or its
affiliates with respect to the exercise of such rights, and the Operating
Trustee shall not consult with Grantor with respect to such rights. As used
herein, the term "affiliates" shall have the definition adopted in 47 U.S.C.
ss. 153(1), provided however, that for purposes of this Agreement (i) neither
the Trust nor any of its subsidiaries shall be deemed to be an affiliate of
Grantor or of any of Grantor's affiliates, and (ii) neither MOTH nor any of its
subsidiaries shall be deemed to be an affiliate of Grantor or of any of
Grantor's affiliates after the closing of the TWE Restructuring. The Trust
shall retain and hold, and the Operating Trustee shall manage, the Disposition
Property in accordance with, and subject to, the terms and conditions set forth
in this Agreement, the TWE Partnership Agreement, the TWE Restructuring
Documents to the extent the Trust is a party thereto or is otherwise bound
thereby, and any other applicable constitutional document or other agreement
setting out rights and responsibilities with respect to any Disposition
Property entered into in connection with an Alternate Disposition, Public Sale
or Private Sale (collectively, the "Governing Agreements"). The Operating
Trustee shall have the authority to sell, transfer, assign, pledge or otherwise
dispose of or encumber the Disposition Property only to the extent and in the
manner provided in the Governing Agreements. The Operating Trustee shall cause
the Trust to comply with the applicable terms of the Governing Agreements.

      5.   Divestiture of the Disposition Property.

           (a) The Operating Trustee shall, in accordance with the terms of
this Agreement, divest the Disposition Property. Subject to compliance by the
Operating Trustee with its obligations under this Agreement, the decision to
divest part or all of the Disposition


                                     -10-



Property shall be made by the Operating Trustee in its sole discretion. Subject
to Section 5(c), Grantor shall not take any action to block a sale by the
Operating Trustee on any grounds other than the Operating Trustee's Malfeasance
(as defined in Section 7(h)).

           (b) During the period commencing with the Closing and ending five
(5) years thereafter (the "5-Year Period"), except as otherwise provided
herein, the Operating Trustee shall pursue such registration rights as are
available with respect to all or any portion of the Disposition Property
pursuant to the TWE Partnership Agreement, the TWE Restructuring Documents or
otherwise, in a manner intended to maximize the value received by Grantor,
consistent with the goal of concluding a complete divestiture of the
Disposition Property by the end of the 5-Year Period. The Operating Trustee
shall have complete authority to prosecute such registration rights, including
authority to engage in such litigation as may be necessary. In addition, if any
of the Disposition Property is saleable in the public market either under an
already effective registration statement or without the requirement of a
registration statement under Federal or state securities laws, then the
Operating Trustee may also seek to effect a sale pursuant thereto in a manner
intended to maximize the value received by Grantor, consistent with the goal of
concluding a complete divestiture of the Disposition Property by the end of the
5-Year Period. A sale by the Operating Trustee in the manner permitted in this
Section 5(b) is referred to herein as a "Public Sale." The Operating Trustee
shall not otherwise have the power to dispose of any of the Disposition
Property during the 5-Year Period, except pursuant to one or more Alternate
Dispositions or Private Sales (as defined in Section 5(g)), or as provided in
Section 13.

           (c) Notwithstanding the foregoing, at any time during the 5-Year
Period, Grantor may propose any one or more Alternate Dispositions (as defined
below) with respect to


                                     -11-



all or part of the Disposition Property, which the Operating Trustee shall be
obligated to use reasonable best efforts to cause the Trust to effect
(including by becoming a party to agreements related thereto, subject to
appropriate indemnification from Grantor and its affiliates), unless such
Alternate Disposition is withdrawn by Grantor. If necessary to effect an
Alternate Disposition, the Operating Trustee will discontinue (and will not
initiate) any efforts to effect a Public Sale, if inconsistent with the terms
of such Alternate Disposition, until the Alternate Disposition is closed or
terminated without closing. The following types of transactions or combinations
thereof constitute "Alternate Dispositions":

                (i) A sale or other transfer to any person or persons
           unaffiliated with Grantor for cash.

                (ii) A sale or other transfer, conversion or exchange to any
           person or persons unaffiliated with Grantor for any consideration
           other than cash, provided it is not for Restricted Consideration.
           "Restricted Consideration" is an interest in AOL Time Warner or an
           entity that, directly or indirectly, owns interests in cable systems
           or cable programming networks which are attributable under then
           current FCC Regulations to AOL Time Warner.

                (iii) A sale or other transfer, conversion or exchange to any
           person or persons unaffiliated with Grantor for Restricted
           Consideration. For the avoidance of doubt, the conversion of TWE to
           a corporation in connection with the registration rights process
           under the TWE Partnership Agreement, and the TWE Restructuring, each
           would be deemed to be an Alternate Disposition for Restricted
           Consideration.


                                     -12-



                (iv) A transaction: (A) with any person or persons unaffiliated
           with Grantor; (B) which involves a security linked to any of the
           Disposition Property or a security that would be deemed to be a
           "derivative security" (as defined in Rule 16a-1(c) under the
           Securities Exchange Act of 1934, as amended) with respect to any of
           the Disposition Property, or (even if not a security) which would
           (were it a security) be considered such a derivative security, or
           which transfers some or all of the economic risk of ownership of any
           of the Disposition Property, including, without limitation, any
           forward contract, equity swap, put or call, put or call equivalent
           position, collar, non-recourse loan, sale of exchangeable security
           or similar transaction; (C) which has a term ending no more than
           five (5) years following the Closing; and (D) pursuant to which the
           Trust receives cash and retains an economic interest equal to no
           more than 20% of the risk of loss or opportunity for gain or an
           economically equivalent combination of risk of loss and opportunity
           for gain; provided, however, that any such transaction shall have
           economics similar to a collar and the spread on the collar shall
           include the trading price of the relevant Disposition Property on
           the day the transaction is entered into (a "Derivative
           Transaction").

           (d) For the avoidance of doubt, Disposition Property shall, unless
divested by the Trust in accordance with this Section 5, be retained by the
Trust and not distributed to Grantor or its affiliates, except as provided
pursuant to Section 13.

           (e) In the event that all or part of the Disposition Property is
divested in an Alternate Disposition in return for any consideration that does
not constitute Restricted Consideration, the following shall apply: (i) cash
consideration will be distributed to Grantor, in


                                     -13-



accordance with Section 6; and (ii) non-cash consideration will remain in the
Trust as Disposition Property unless its distribution to Grantor is approved by
the FCC's Media Bureau (the "Media Bureau"). The Operating Trustee will
promptly file a written request with the Media Bureau, styled as a "Request to
Distribute Non-Cash, Non-Restricted Consideration," seeking approval to
distribute any such non-cash consideration that it receives to Grantor. The
distribution of such non-cash consideration to Grantor shall be deemed approved
unless the Media Bureau notifies the Operating Trustee, in writing and within
30 days of receipt of such notice from the Operating Trustee, that it objects
to such distribution, provided however, that the Media Bureau may, by written
notice to the Operating Trustee, extend the 30 day period for an additional 30
days if necessary to complete its review, in which case the distribution will
be deemed approved unless the Media Bureau notifies the Operating Trustee, in
writing and within 60 days of its receipt of the Operating Trustee's request,
that it objects to the proposed distribution. If the Media Bureau objects to
the distribution of any non-cash consideration within 30 days of notice from
the Operating Trustee (or, in the event the Media Bureau's review period is
extended as provided herein, within 60 days of the Operating Trustee's notice),
then such non-cash consideration shall constitute Disposition Property and
shall be retained by the Trust. If at any time after an Alternate Disposition
any Restricted Consideration received in such Alternate Disposition ceases to
be Restricted Consideration, the consideration will be treated as set forth in
this Section 5(e) with respect to consideration that is not Restricted
Consideration.

           (f) Following an Alternate Disposition, and subject to the
limitations contained in Section 5(g), the Operating Trustee will retain the
power for the remainder of the 5-Year Period to dispose of in a Public Sale any
remaining Disposition Property, other than that which is the subject of a
Derivative Transaction, in a manner intended to maximize the value


                                     -14-



received by Grantor, consistent with the goal of concluding a complete
divestiture of the Disposition Property by the end of the 5-Year Period and
subject to the provisions of the Governing Agreements. Following an Alternate
Disposition which is a Derivative Transaction, the Operating Trustee will not
take any action during the 5-Year Period (or, if shorter, during the period of
time such Disposition Property is the subject of the Derivative Transaction) to
effect a Public Sale of that part of the Disposition Property which is the
subject of the Derivative Transaction, without the consent of Grantor.

           (g) The Operating Trustee acknowledges that the registration rights
process currently provided for in the TWE Partnership Agreement has been
suspended. Grantor represents to the Operating Trustee that the Restructuring
Agreement provides that in the event of termination of the Restructuring
Agreement, the registration rights process in effect at the time of the
execution of the Restructuring Agreement will be reinstated at the same point
at which it was suspended (with the general rule being that the appraisal
previously completed in connection with such process shall be prepared again
and, in the event the investment banking firm that conducted such earlier
appraisal is not at such time eligible to be engaged, a new investment banking
firm will have to be selected and engaged, provided that in certain exceptional
circumstances the existing appraisal may be used). The Operating Trustee shall
take all actions necessary to implement the TWE Restructuring in accordance
with the terms of the TWE Restructuring Documents, will abide by the TWE
Restructuring Documents as if it were a party thereto, and will not take any
action that would result in a breach of the TWE Restructuring Documents by
Grantor or any of its affiliates. The Operating Trustee further agrees that,
following the closing of the TWE Restructuring, it will dispose of any
consideration received and assets retained in connection with the TWE
Restructuring in a manner consistent with the


                                     -15-



terms of this Agreement and the TWE Restructuring Documents, provided that
following the closing of the TWE Restructuring:

                (i) The Operating Trustee will not take any action during the
           90-day period following the closing of the TWE Restructuring to
           dispose of any publicly traded common stock of AOL Time Warner held
           by the Trust in a Public Sale, unless so requested by Grantor;

                (ii) The Operating Trustee will not take any action during the
           180-day period following the closing of the TWE Restructuring to
           effect any initial public offering of stock in MOTH, which as a
           result of the TWE Restructuring will become a subsidiary of AOL Time
           Warner and will hold a majority interest in TWE and certain other
           assets, pursuant to any applicable registration rights, unless so
           requested by Grantor; and

                (iii) If: (A) the consideration received or assets retained by
           the Trust in the TWE Restructuring includes a partnership interest
           in TWE; (B) the TWE Partnership Agreement (as amended and restated
           in connection with the TWE Restructuring) or any other TWE
           Restructuring Document restricts the rights of Grantor or the Trust
           to sell or otherwise transfer such partnership interest for a period
           of time following the closing of the TWE Restructuring not to exceed
           two years; (C) such amended and restated TWE Partnership Agreement
           (or a related agreement) provides procedures for the private sale of
           such partnership interest after such two year period; and (D) within
           three years following the closing of the TWE Restructuring Grantor
           has not elected to have the Trust effect such a private sale as an
           Alternate Disposition; then the Operating Trustee shall have the
           right


                                     -16-



           following such three year period (and not prior thereto) to effect
           such a private sale pursuant to such provisions (such a sale of such
           partnership interest pursuant to such provisions, a "Private Sale").
           For the avoidance of doubt, the term "Private Sale" may include a
           sale to MOTH or AOL Time Warner pursuant to an appraisal process set
           forth in a TWE Restructuring Document.

           (h) Neither Grantor nor any of its affiliates will be permitted to
be a purchaser in a Public Sale or a Private Sale or a counterparty in a
Derivative Transaction.

           (i) If any of the Disposition Property remains at the end of the
5-Year Period, the Operating Trustee will have the authority and be directed to
divest whatever portion of the interest remains as quickly as possible, and in
all events within six (6) months thereafter.

           (j) The Operating Trustee shall not divest all or part of the
Disposition Property until all necessary governmental approvals, if any, have
been received.

      6.   Distribution of Proceeds of Sale; Dividends.

           (a) In the event of any disposition involving all or part of the
Disposition Property, the Operating Trustee shall cause to be distributed to
Grantor as soon as practicable following receipt: (i) any cash; and (ii)
following approval by the Media Bureau pursuant to Section 5(e), any assets
which do not constitute Restricted Consideration. Such amounts may be reduced
by the amount of fees or expense reimbursements then owed by Grantor to the
Trustees.

           (b) In the event that dividends or distributions are paid in respect
of any portion of the Disposition Property, the Operating Trustee shall cause
to be distributed to Grantor as soon as practicable following receipt any such
dividends or distributions to the extent they consist of: (i) any cash; or (ii)
following approval by the Media Bureau pursuant to the procedure described in
Section 5(e), any assets which do not constitute Restricted Consideration.


                                     -17-



      7.   Trustee Obligations, Fees and Indemnification.

           (a) The Trust shall be administered by the Operating Trustee in
accordance with the provisions of this Agreement and applicable FCC
Regulations.

           (b) The Operating Trustee shall maintain such records, files and
books as the Operating Trustee, in the Operating Trustee's reasonable
discretion, deems necessary or appropriate to enable the Operating Trustee to
carry out the terms and conditions of this Agreement and to record the actions
taken by the Operating Trustee in the performance of the Operating Trustee's
duties under this Agreement.

           (c) The Operating Trustee is expressly authorized to incur and
obligate Grantor to pay all charges, taxes and other expenses that are
reasonable, necessary and proper in connection with the preparation, execution
and delivery of this Agreement and the performance by the Operating Trustee of
its duties under this Agreement. Grantor shall pay directly all such charges,
taxes and expenses or reimburse the Operating Trustee therefor within thirty
(30) days after receipt of the Operating Trustee's notice and documentation
under Section 7(e).

           (d) In compensation for the Operating Trustee's services under this
Agreement, Grantor will pay the Operating Trustee customary fees for the time
that the Operating Trustee spends in connection with the formation and
administration of the Trust. All such fees shall become due and payable within
thirty (30) days after the Operating Trustee has given notice thereof to
Grantor under Section 7(e).

           (e) The Operating Trustee shall provide timely and adequate written
notice to Grantor (no more frequently than once each month) specifying in
reasonable detail: (i) the charges, taxes and other expenses to be paid
directly by Grantor to third parties or for which


                                     -18-



Grantor shall reimburse the Operating Trustee (together with customary
supporting documentation); and (ii) the fees due to be paid to the Operating
Trustee.

           (f) The Operating Trustee shall provide to Grantor: (i) within
fifteen (15) days of receipt thereof, any accountings received by the Operating
Trustee with respect to the operations of TWE or any other issuer of securities
comprising Disposition Property, except to the extent disclosure of such
information to Grantor is prohibited by the terms of Section 12; and (ii)
within fifteen (15) days of receipt of a written request by Grantor, an
accounting of the expenses of the Operating Trustee incurred directly or by
third parties for the performance of services to the Operating Trustee in
connection with the performance of the Operating Trustee's duties under this
Agreement.

           (g) Except as specifically provided in this Agreement, the Operating
Trustee shall not be entitled to any other fee or other payment hereunder or
otherwise, including any termination fee.

           (h) Grantor hereby agrees to indemnify each Trustee and hold each
Trustee harmless against all claims, actions, proceedings, suits, costs of
defense (including reasonable and customary attorneys' and accountants' fees
and disbursements), expenses, liabilities, judgments, damages, awards and
settlements asserted against or incurred by such Trustee in connection with, or
in any way arising directly or indirectly from, the performance by such Trustee
of its duties under this Agreement, including claims and liabilities arising
from any actions taken by the Operating Trustee in furtherance of its
obligation to sell as quickly as possible any of the Disposition Property that
remains after the 5-Year Period, provided that the indemnification provided for
in this Section 7(h) shall not apply to any claims or liabilities arising from
such Trustee's Malfeasance. For purposes of this Agreement, a Trustee's


                                     -19-



"Malfeasance" shall mean such Trustee's bad faith, gross negligence, willful
misconduct or other action inconsistent with the terms of this Agreement or any
of the other Governing Agreements.

           (i) Except as incurred as a result of such Trustee's Malfeasance, a
Trustee shall not be liable with respect to actions taken by it in reliance
upon any paper, document or signature reasonably believed by such Trustee to be
genuine and to have been signed by the proper party that is not in fact
genuine. A Trustee shall not be liable for any error of judgment in any act
done or omitted, nor for any mistake of fact or law, nor for anything which
such Trustee may do or refrain from doing in accordance with this Agreement,
absent such Trustee's Malfeasance. A Trustee may consult with accountants,
attorneys and other advisors, and any action taken in accordance with the
advice of such advisor shall be presumptively done in good faith.

           (j) The Operating Trustee shall have no duty or liability to Grantor
with respect to any change in the value of any of the Disposition Property
resulting from TWE's operations or otherwise (except for the Operating
Trustee's Malfeasance) during the Trust Term.

           (k) Neither Trustee shall be required to furnish a bond or other
security in any jurisdiction for the faithful performance of such Trustee's
duties.

           (l) Except where the provision of Section 5(i) applies, the
Operating Trustee shall manage the property of the Trust, consistent with the
terms of this Agreement, in a manner intended to maximize the value of the
properties of the Trust, Trust II and Trust III, taken as a whole, and the
Trust, Trust II and Trust III shall cooperate with each other in connection
with any transaction by any of them.

           (m) The Trustee shall assist Grantor and Grantor's affiliates and
shall cooperate fully in all tax matters relating to the Trust or its assets,
including, without limitation,


                                     -20-



in connection with the preparation and filing of any tax returns or reports
which Grantor or any of Grantor's affiliates is required to prepare or file
with respect to the Trust or its assets.

      8. Trustee Selection. The Delaware Trustee, and any successor Delaware
Trustee, shall be either a natural person who is a resident of the State of
Delaware or a legal entity having its principal place of business in the State
of Delaware, in each case appointed by Grantor. The Operating Trustee shall be
appointed by Grantor after approval by the Media Bureau. Each of Trust I, Trust
II and Trust III shall have the same operating trustee and the same Delaware
trustee, respectively. No Trustee may be a director, officer, manager, agent or
employee of Grantor or its affiliates immediately prior to or at any time while
serving as Trustee, nor may any Trustee have any extratrust business, personal
or familial relationship with Grantor or its affiliates while serving as
Trustee that is inconsistent with any applicable FCC Regulations. In the event
that a Trustee enters into any relationship prohibited by this Section 8 at any
time while serving as Trustee, such Trustee shall resign in the manner provided
in Section 9.

      9.   Trustee Removal, Resignation, and Replacement.

           (a)  Grantor may not remove or replace a Trustee at will.

           (b) The rights and duties of the Trustees hereunder (other than a
Trustee's rights to receive payments to the extent accrued prior to termination
and to be indemnified hereunder) shall terminate upon such Trustee's incapacity
to act, death or bankruptcy or other insolvency. No interest in the Disposition
Property, nor any of the rights and duties of an incapacitated, deceased,
bankrupt or insolvent Trustee, may be transferred by such Trustee by will,
devise, succession or in any other manner except as provided in this Agreement.


                                     -21-



           (c) A Trustee may resign by giving thirty (30) days advance written
notice of resignation to Grantor, provided that such Trustee agrees that any
such resignation shall not become effective until a successor Trustee has been
appointed.

           (d) In the event of a Trustee's resignation, incapacity to act,
death or bankruptcy or other insolvency, such Trustee shall be succeeded by a
successor Trustee chosen by Grantor in compliance with FCC Regulations and the
terms of this Agreement. Any successor Trustee shall succeed to all of the
rights and obligations of the Trustee replaced hereunder upon execution by such
successor Trustee of a counterpart of this Agreement. A successor Trustee shall
not be liable for breaches of this Agreement committed by a predecessor
Trustee.

           (e) Notwithstanding any other provision of this Section 9, a Trustee
that resigns or is removed as trustee of Trust II or Trust III (other than upon
termination of such trust) shall likewise resign or be removed as Trustee of
the Trust.

      10.  Trustee Advisors.

           (a) The Operating Trustee shall have the right to retain such
accountants, attorneys, investment bankers, managing underwriters and other
advisors (collectively, "Advisors") as are necessary or appropriate to enable
the Operating Trustee to perform in a prudent and competent manner the duties
and obligations of the Operating Trustee under this Agreement; provided,
however, that: (i) the fees and expenses of such Advisors shall be reasonable
and customary; and (ii) such Advisors do not have any material business
relationship with AOL Time Warner during the term of the Trust. In order to
facilitate an expeditious divestiture, the Operating Trustee may retain any
Advisors retained prior to the Contribution Date by AT&T, Comcast or their
respective affiliates, provided, however, that: (i) such Advisors


                                     -22-



are solely accountable to the Operating Trustee in respect of advice or
services rendered to the Operating Trustee in connection with divestiture of
any Disposition Property; and (ii) such Advisors shall not continue to
represent AT&T Comcast or its affiliates in connection with divestiture of such
Disposition Property. The Operating Trustee shall be required to provide
Grantor with notice and documentation of fees and expenses incurred in
connection with the retention of Advisors pursuant to this Section 10(a).

           (b) Grantor and its affiliates also shall have the right to retain
Advisors to assist the Operating Trustee's Advisors with the divestiture of the
Disposition Property (including any Advisors retained by AT&T or Comcast prior
to the Contribution Date, to the extent they have not been retained by the
Operating Trustee pursuant to the previous subsection); provided, however, that
the Operating Trustee shall be free to accept or reject any advice offered by
such Advisors and shall be privy to any instructions that Grantor may give to
such Advisors, and provided further, that, for avoidance of doubt, the
Grantor's Advisors may communicate with the Operating Trustee's Advisors, but
shall not communicate directly with the Operating Trustee except in the
presence of Grantor and Operating Trustee's Advisors.

           (c) The Operating Trustee shall direct any Advisors that it retains,
and Grantor shall direct any Advisors that it retains, with regard to the
divestiture of the Disposition Property, to take appropriate steps to ensure
that such Advisors do not act as a conduit for communications between the
Operating Trustee and Grantor that are otherwise prohibited under the terms of
this Agreement.

      11. Grantor Involvement in TWE Management. Except as provided in Section
12(a), Grantor and its affiliates shall not have an interest in, control of or
involvement in the operation or management of TWE, or seek to influence the
operation or management of TWE or any cable


                                     -23-



system in which TWE has an interest, other than Kansas City Cable Partners and
Texas Cable Partners, L.P., on account of AT&T Comcast's 50% general
partnership interest therein which is held outside of TWE, provided that
Grantor and its affiliates shall not: (i) receive information from Kansas City
Cable Partners or Texas Cable Partners, L.P. regarding the price, terms or
conditions that TWE, or any affiliate of AOL Time Warner that is a successor to
TWE's interest in Kansas City Cable Partners or Texas Cable Partners, L.P. or
any of TWE's or such successor's affiliates (other than Kansas City Cable
Partners or Texas Cable Partners, L.P. or any of their subsidiaries),
negotiates for carriage of video programming on the cable systems owned by
Kansas City Cable Partners or Texas Cable Partners, L.P.; or (ii) provide
information to Kansas City Cable Partners or Texas Cable Partners, L.P.
regarding the price, terms or conditions that Grantor or its affiliates
negotiate for the carriage of video programming on the cable systems owned by
Grantor or its affiliates. For purposes of this Section 11, the term "TWE"
shall include TWE and any other issuer of securities or ownership interests
constituting Disposition Property. This Section 11 will cease to apply with
respect to Kansas City Cable Partners or Texas Cable Partners, L.P., as the
case may be, at such time as neither TWE nor any other affiliate of AOL Time
Warner owns any interest in such entity.

      12.  Communications.

           (a)  Communications Regarding Operation and Management of TWE.

                (i) The Operating Trustee shall not provide any information to
           Grantor concerning the operation or management of TWE or the
           operation or management of the cable systems in which TWE has a
           direct or indirect interest, except that the Operating Trustee shall
           use its reasonable best efforts to obtain and provide Grantor with
           financial statements and tax information with respect to


                                     -24-



           TWE and the MOC TWE Interest as and when furnished by TWE and as
           required by Grantor or its affiliates for compliance with securities
           and tax laws, rules and regulations, or other applicable legal or
           regulatory requirements. None of Grantor, or any of its affiliates,
           or any of its or their officers, directors or employees, shall
           communicate with the Operating Trustee, directly or indirectly,
           including indirectly through their Advisors, regarding the operation
           or management of TWE or the operation or management of any cable
           system in which TWE has an interest.

                (ii) The Operating Trustee shall have such access to Grantor
           and its affiliates' personnel, books, records and facilities related
           to the Disposition Property as may be reasonably necessary for the
           Operating Trustee to fulfill its obligations hereunder.

                (iii) Any communications between the Operating Trusteee and
           Grantor or its affiliates permitted by this subsection (a) shall be
           in writing.

           (b) Communications Regarding Public Sale, Private Sale or Alternate
Disposition. The Operating Trustee and Grantor and its affiliates may engage in
communications in order to facilitate divestiture of the Disposition Property
through any Public Sale, Private Sale or Alternate Disposition. The Operating
Trustee shall provide periodic reports (no less frequently than quarterly
during the 5-Year Period and no less frequently than monthly thereafter) to
Grantor (with a copy to the Media Bureau) describing the Operating Trustee's
efforts to accomplish divestiture of the Disposition Property through any
Public Sale, Private Sale or Alternate Disposition, provided, however, that to
the extent such reports contain information that Grantor deems confidential,
such reports shall be provided to the Media Bureau


                                     -25-



only after such confidential information has been redacted. In the event that
such reports are provided to the Media Bureau in redacted form, the unredacted
versions of such reports will be maintained by the Operating Trustee, or its
designee, at a location in the Washington, D.C. area, and shall be made
available upon request for inspection by the Media Bureau during normal
business hours. Upon request by the Media Bureau, the Operating Trustee shall
file the unredacted version of any such report with the Media Bureau
accompanied by a request for confidential treatment. Grantor will use its
reasonable best efforts, consistent with the terms of this Agreement and
applicable FCC Regulations, to assist the Operating Trustee in accomplishing
the divestiture of the Disposition Property, including using its reasonable
best efforts to provide such information as is required by the Operating
Trustee to effect such divestiture.

           (c)  Communications Regarding Fiduciary Matters. Communications
between the Trustees and Grantor regarding the fiduciary obligations owed by
the Trustees to Grantor shall be permitted at any time.

           (d) The Operating Trustee shall retain copies of all written
communications between the Operating Trustee or its Advisors and Grantor, its
affiliates or its Advisors. The Operating Trustee shall prepare (or, as
appropriate, instruct its Advisors to prepare) and retain a contemporaneous
written summary of all oral communications between the Operating Trustee or its
Advisors and Grantor, its affiliates or its Advisors, pursuant to subsections
(b) and (c) of this Section 12, provided that such summary shall not be
required for oral communications that are ministerial or non-substantive in
nature, or are otherwise not material to the performance of the Operating
Trustee's fiduciary obligations to Grantor or its efforts to (a) divest the
Disposition Property or (b) effect an Alternate Disposition in accordance with
the terms of this Agreement.


                                     -26-



All written communications and summaries of oral communications shall be
maintained by the Operating Trustee, or its designee, at a location in the
Washington, D.C. area, and shall be made available upon request for inspection
by the Media Bureau during normal business hours.

           (e) Subject to a customary confidentiality agreement and to the
terms of any other agreement to which the Trust is a party or otherwise
subject, the Operating Trustee shall permit prospective purchasers of the
Disposition Property in an Alternate Disposition (at the request of the
Grantor) or a Private Sale (at the Operating Trustee's discretion) to have
access to any and all financial or operational information to which the
Operating Trustee has access, as may be relevant to divestiture of the
Disposition Property.

      13.  Termination.

           (a) Subject to the provisions of Section 17(e), the Trust shall
dissolve upon written election by Grantor delivered to the Trustees, provided
that one of the following events has occurred (any such event, a "Dissolution
Event"):

                (i) divestiture of all of the Disposition Property and the
           payment of all proceeds to the order of Grantor with respect to such
           divestiture, in the manner provided in Sections 5(e) and 6(a);

                (ii) expiration of the six-month period following the 5-Year
           Period, provided, however, that if any portion of the Disposition
           Property remains in the


                                     -28-



           Trust at the expiration of the six-month period following the 5-Year
           Period, the Trust will continue until the FCC either approves the
           dissolution of the Trust or the remainder of the Disposition Property
           has been divested and all proceeds due to the order of Grantor with
           respect to such divestiture have been paid, in the manner provided in
           Sections 5(e) and 6(a); or

                (iii) AT&T Comcast ceases directly or indirectly to own any
           beneficial interest in the Trust.

           (b) Upon dissolution of the Trust, the Operating Trustee shall take
such action as is necessary or appropriate to deliver to the order of Grantor,
or such other party designated by Grantor in writing to the Operating Trustee,
all property then held by the Trust or the Operating Trustee on behalf of the
Trust pursuant to this Agreement, subject to satisfaction (whether by payment
or reasonable provision therefor) of claims of all creditors of the Trust
(other than Grantor) including, without limitation, the Trustees. The Operating
Trustee shall have a reasonable period to conclude the administration of the
Trust, and shall be compensated for all reasonably necessary services performed
after the dissolution date. Following completion by the Operating Trustee of
the actions required by this Section 13(b), the Operating Trustee shall provide
written notice to Grantor and, upon written request of Grantor, the Trustees
shall terminate the legal existence of the Trust by canceling the Certificate
of Trust in accordance with the Act.

           (c) Notwithstanding any other provision of this Section 13, upon a
Dissolution Event, Grantor may elect, in lieu of dissolving the Trust, to
terminate this Agreement and to convert the Trust into a Delaware limited
liability company, Delaware corporation or other legal entity, which conversion
shall be upon such terms as Grantor shall deem appropriate;


                                     -29-



provided that upon completion of such conversion all rights, obligations,
assets and liabilities of the Trust remain, under applicable law, rights,
obligations, assets and liabilities of the entity so created. The Trustees
shall cooperate with Grantor in connection with the foregoing.

           (d) At any time, subject to the Governing Agreements, Grantor may
cause the Trustees to merge the Trust with Trust II or Trust III, or to
transfer all of the assets and liabilities of the Trust (including, without
limitation, the Disposition Property) to Trust II or Trust III, or to accept a
transfer of all of the assets and liabilities of Trust II or Trust III to the
Trust; provided that, in each case and to the extent required under the
Governing Agreements, the successor or transferee trust shall assume the
obligations of the merged or transferor trust under the Governing Agreements
(other than the Declaration of Trust of the merged or transferor trust). For
purposes of this Section 13(d), the term "Governing Agreements" includes the
"Governing Agreements" as defined in this Agreement and in the Declaration of
Trust of the successor or transferee, or merged or transferor, trust, as the
case may be.

      14. Modification. This Agreement shall not be modified except by an
instrument in writing executed by Grantor and the Operating Trustee; provided
that the rights, duties, responsibilities and compensation of the Delaware
Trustee shall not be changed without the prior written consent of the Delaware
Trustee. No modifications of this Agreement, except for modifications that are
insubstantial and immaterial, shall be made unless approved by the Media
Bureau. A request for approval of a modification of this Agreement shall be
deemed approved unless the Media Bureau notifies the Operating Trustee, in
writing and within 14 days of receipt of such request from the Operating
Trustee, that it objects to such modification. A copy of any insubstantial and
immaterial modification in the Trust shall be filed with the FCC within ten
days following the execution thereof, with a copy to the Media Bureau.


                                     -30-



The parties shall cooperate in the modification of this Agreement in the event
changes or modifications are needed in order to bring this Agreement and the
transactions contemplated hereby into compliance with applicable FCC
Regulations or other applicable laws.

      15. Assignment. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their respective permitted successors and
permitted assigns. Subject to the power to delegate the performance of
ministerial responsibilities hereunder as deemed necessary by the Operating
Trustee, this Agreement shall not be assignable by the Trustees. Grantor shall
be entitled to assign its rights hereunder to AT&T Comcast or any subsidiary
thereof or any person who becomes the direct or indirect beneficial owner of
the Disposition Property as a result of a merger or transfer of all or
substantially all the assets of AT&T Comcast or any of its subsidiaries.

      16. Confidentiality. This Agreement and all matters concerning the
performance, enforcement and interpretation hereof shall be kept in strict
confidence by the parties, except where disclosure is required by law, rule or
regulation (including the Federal securities laws or FCC Regulations), to carry
out the express purposes and terms of this Agreement, or in connection with any
claims or actions relating to this Agreement.

      17.  Miscellaneous.

           (a) If any part of any provision of this Agreement or any other
agreement, document or writing given pursuant to or in connection with this
Agreement shall be invalid or unenforceable under applicable law, said part
shall be ineffective to the extent of such invalidity only, without in any way
affecting the remaining part of said provision or the remaining provisions of
this Agreement.


                                     -31-

hereto, and any claims and disputes relating thereto, shall be governed by and
construed in accordance with the laws of the State of Delaware (not including
the choice of law rules thereof).

           (d) This Agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original, and all of which together
shall be deemed to be one and the same instrument.

           (e) The provisions of Sections 7, 12(f), 14, 15, 16 and 17 shall
remain in effect, and shall survive, any termination of the Trust.

           (f) The failure of Grantor or a Trustee to exercise or enforce any
right or provision of this Agreement shall not constitute a waiver of such
right or provision.

           (g) This Agreement, together with the Certificate of Trust, is the
complete and exclusive agreement between the parties with respect to the
creation, operation and termination of the Trust, superseding and replacing any
and all prior agreements, communications and understandings, written or oral,
regarding such Trust.

           (h) Neither Trustee shall have any duty or other obligation to pay,
provide or arrange for the provision of funds necessary to perform such
Trustee's duties under this Agreement, other than the provision of the written
notices to Grantor pursuant to Section 7 hereof. Neither Trustee shall have any
personal liability for the payment of any Trust expense or obligation to third
parties whatsoever.


                                     -32-



      IN WITNESS WHEREOF, the parties hereto have executed this Agreement or

      WHEREAS, the parties hereto now wish to establish the terms and

      WHEREAS, Edith E. Holiday wishes to serve as Operating

      NOW, THEREFORE, in consideration of the foregoing and mutual covenants
and agreements hereinafter set forth, the parties hereto agree as follows:

      1.   General Provisions.

           (a) Name. The name of this trust is "TWE Holdings II Trust." The
Trust's business may be conducted under the name of the Trust or any other name
or names selected by the Operating Trustee.

           (b) Principal Office. The principal office of the Trust shall be 801
West Street, 2nd Floor, Wilmington, Delaware 19810, or such other place within
the State of Delaware as may from time to time be designated by the Operating
Trustee, provided, however, that the Operating Trustee shall not locate its
offices at the offices of AT&T Comcast or its affiliates, as defined below. The
Operating Trustee shall give prompt notice of any change in the address of its
principal office to Grantor and the Delaware Trustee. Neither the Delaware
Trustee nor the Operating Trustee shall maintain an office outside of the State
of Delaware for the conduct of the business of the Trust or conduct the
business of the Trust outside of the State of Delaware; provided that the
Operating Trustee may from time to time conduct the business of the Trust
outside of the State of Delaware if reasonably required for the conduct of such
business. The


                                      -6-


Operating Trustee shall comply with such conditions relating to the immediately
preceding sentence as Grantor shall reasonably request.

           (c) Delaware Trustee. The address of the Delaware Trustee in
Delaware is One Little Falls Centre I, Suite 210, 2711 Centreville Road,
Wilmington, Delaware 19808. The Delaware Trustee is appointed to serve as the
trustee of the Trust in Delaware for the sole purpose of satisfying the
requirements of Section 3807 of the Act that the Trust have at least one
trustee with a principal place of business in Delaware. The Delaware Trustee
shall be entitled to receive customary fees for its services. It is understood
and agreed by the parties hereto that the Delaware Trustee shall have none of
the rights, duties or liabilities of the Operating Trustee. The rights and
duties of the Delaware Trustee shall be limited to (a) accepting legal process
served on the Trust in Delaware and (b) the execution of any certificates
required to be filed with the Delaware Secretary of State which the Delaware
Trustee is required to execute under Section 3811 of the Act. To the extent
that, at law or in equity, the Delaware Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or Grantor, it is hereby
understood and agreed by the parties hereto, including Grantor, that such
duties and liabilities are replaced by the duties and liabilities of the
Delaware Trustee expressly set forth in this Agreement. The Delaware Trustee
and the Operating Trustee are referred to herein collectively as the "Trustees"
and each individually as a "Trustee."

           (d) Declaration of Trust. The Delaware Trustee and the Operating
Trustee each hereby declares that it will hold the assets of the Trust in trust
upon and subject to the conditions set forth herein for the benefit of Grantor,
the holder of 100% of the beneficial interests in the Trust, and in compliance
with all applicable rules, regulations and orders of the Federal Communications
Commission ("FCC Regulations"). It is the intention of the parties


                                      -7-


hereto that the Trust be a statutory trust under the Act. The Delaware Trustee
and the Operating Trustee are hereby authorized to execute any amendment or
restatement of the Certificate of Trust so long as such amendment or
restatement is not inconsistent with the provisions hereof. The Trust is not
intended to be, shall not be deemed to be, and shall not be treated as, a
general partnership, limited partnership, joint venture, corporation or joint
stock company.

           (e) No Individual Ownership. Title to all of the assets of the Trust
shall be vested in the Trust until the Trust dissolves or is converted in
accordance with Section 13 hereof; provided, however, if the applicable laws of
any jurisdiction require that title to any part of the assets of the Trust be
vested in a trustee of the Trust, then title to that part of the assets of the
Trust shall be vested in the Operating Trustee to the extent so required, but
the beneficial interest with respect to such asset shall remain in the Trust
for the benefit of the Trust beneficiaries.

           (f) Tax Treatment. The parties hereby agree that the Trust shall be
treated as a "grantor trust" or, in the event the Trust shall be engaged in the
conduct of a business for profit, as a business entity that is disregarded as
separate from Grantor for purposes of the U.S. Federal, state and local tax
laws, and further agree: (i) not to take any position (or cause the Trust to do
so), in a tax return or otherwise, or take any other action, that is
inconsistent with such treatment; and (ii) to take all commercially reasonable
actions necessary to cause the Trust to be so treated.

      2.   Contribution to the Trust.

           (a)  The date on which the Trust 2 Conversion was
completed (i.e., the date hereof) is referred to in this
Agreement as the "Contribution Date".

           (b) Following the Contribution Date and during the Trust Term (as
defined in Section 3), except as otherwise provided by this Agreement, the
Trust shall have legal and record


                                      -8-


ownership of the Restructuring Proceeds and all other assets constituting
Disposition Property (as defined in Section 4).

           (c) Grantor represents and warrants to the Operating Trustee that:
(i) the MOTH Stock Contribution and the Trust 2 Conversion were effected in
accordance with applicable FCC Regulations; (ii) as of the date of the MOTH
Stock Contribution and the date of the Trust 2 Conversion, Grantor had full
right and legal authority to effect such action occurring on such date as
described herein; (iii) immediately after the closing of the TWE Restructuring,
the Restructuring Proceeds will not be subject to any liens or other
encumbrances (other than as created by, or permitted under, this Agreement, the
TWE Restructuring Documents or as arising under securities laws of general
applicability); and (iv) all consents, waivers and approvals of the Federal
Communications Commission ("FCC") and third parties necessary for the MOTH
Stock Contribution and the Trust 2 Conversion have been received and are in
full force and effect.

           (d) If any additional interest in TWC or AOL Time Warner is acquired
by AT&T Comcast or any of its subsidiaries during the Trust Term, AT&T Comcast
shall cause such interest to be contributed to the Trust and become property of
the Trust or, if AT&T Comcast so elects, AT&T Comcast may cause such additional
interest to be contributed to, and become property of, Trust I. Except as
provided herein, no other property may be contributed to the Trust by any party
without the prior written agreement of the Operating Trustee.

      3. Term of the Trust and Irrevocability. The Trust shall be irrevocable
by Grantor and shall have a term that expires at such time as the Trust
terminates in accordance with the provisions of Section 13 (the "Trust Term").

      4. Operating Trustee Control of the Disposition Property. The Operating
Trustee shall have sole and exclusive authority to manage: (a) the
Restructuring Proceeds; (b) any


                                      -9-


additional TWC or AOL Time Warner shares subsequently contributed to the Trust;
(c) any other Restricted Consideration (as defined in Section 5(c)) received by
the Trust; and (d) any other non-cash consideration received by the Trust in an
Alternate Disposition (as defined in Section 5(c)) or as a dividend or
distribution on securities or ownership interests held by the Trust and not
approved by the Media Bureau (as defined in Section 5(e)) for distribution to
Grantor in accordance with Section 5(e) or 6(b), respectively, (such
Restructuring Proceeds, additional TWC or AOL Time Warner shares, other
Restricted Consideration and other non-cash assets received by the Trust and
not approved for distribution, collectively, the "Disposition Property"), and
to exercise any and all rights with respect to any Disposition Property
including, without limitation, the MOTH Stock Assumed Rights and the right to
exercise any voting, director appointment, consent, approval or management
rights arising from the Disposition Property under the TWE Restructuring
Documents, in a manner intended to maximize the value of the Disposition
Property. Grantor shall not retain any voting, director appointment, consent,
approval or management rights with respect to the Disposition Property. Grantor
shall not have any rights to require the Operating Trustee to consult with
Grantor or its affiliates with respect to the exercise of such rights and the
Operating Trustee shall not consult with Grantor with respect to such rights.
As used herein, the term "affiliates" shall have the definition adopted in 47
U.S.C. ss. 153(1), provided, however, that for purposes of this Agreement (i)
neither the Trust nor any of its subsidiaries shall be deemed to be an
affiliate of Grantor or of any of Grantor's affiliates and (ii) neither MOTH
nor any of its subsidiaries shall be deemed to be an affiliate of Grantor or of
any of Grantor's affiliates after the closing of the TWE Restructuring. The
Trust shall retain and hold, and the Operating Trustee shall manage, the
Disposition Property in accordance with, and subject to, the terms and
conditions set forth in this Agreement, the TWE


                                     -10-


Partnership Agreement, the TWE Restructuring Documents to the extent the Trust
is a party thereto or is otherwise bound thereby, and any other applicable
constitutional document or other agreement setting out rights and
responsibilities with respect to any Disposition Property entered into in
connection with an Alternate Disposition, Public Sale or Private Sale
(collectively, the "Governing Agreements"). The Operating Trustee shall have
the authority to sell, transfer, assign, pledge or otherwise dispose of or
encumber the Disposition Property only to the extent and in the manner provided
in the Governing Agreements. The Operating Trustee shall cause the Trust to
comply with the applicable terms of the Governing Agreements.

      5.   Divestiture of the Disposition Property.

           (a) The Operating Trustee shall, in accordance with the terms of
this Agreement, divest the Disposition Property. Subject to compliance by the
Operating Trustee with its obligations under this Agreement, the decision to
divest part or all of the Disposition Property shall be made by the Operating
Trustee in its sole discretion. Subject to Section 5(c), Grantor shall not take
any action to block a sale by the Operating Trustee on any grounds other than
the Operating Trustee's Malfeasance (as defined in Section 7(h)).

           (b) During the period commencing on the date hereof and ending five
(5) years after the AT&T Comcast Transaction Closing (the "5-Year Period"),
except as otherwise provided herein, the Operating Trustee shall pursue such
registration rights as are available with respect to all or any portion of the
Disposition Property pursuant to the TWE Partnership Agreement, the TWE
Restructuring Documents or otherwise, in a manner intended to maximize the
value received by Grantor, consistent with the goal of concluding a complete
divestiture of the Disposition Property by the end of the 5-Year Period. The
Operating Trustee shall have complete authority to prosecute such registration
rights, including authority to engage


                                     -11-


in such litigation as may be necessary. In addition, if any of the Disposition
Property is saleable in the public market either under an already effective
registration statement or without the requirement of a registration statement
under Federal or state securities laws, then the Operating Trustee may also
seek to effect a sale pursuant thereto in a manner intended to maximize the
value received by Grantor, consistent with the goal of concluding a complete
divestiture of the Disposition Property by the end of the 5-Year Period. A sale
by the Operating Trustee in the manner permitted in this Section 5(b) is
referred to herein as a "Public Sale." The Operating Trustee shall not
otherwise have the power to dispose of any of the Disposition Property during
the 5-Year Period, except pursuant to one or more Alternate Dispositions or
Private Sales (as defined in Section 5(g)), or as provided in Section 13.

           (c) Notwithstanding the foregoing, at any time during the 5-Year
Period, Grantor may propose any one or more Alternate Dispositions (as defined
below) with respect to all or part of the Disposition Property, which the
Operating Trustee shall be obligated to use reasonable best efforts to cause
the Trust to effect (including by becoming a party to agreements related
thereto, subject to appropriate indemnification from Grantor and its
affiliates), unless such Alternate Disposition is withdrawn by Grantor. If
necessary to effect an Alternate Disposition, the Operating Trustee will
discontinue (and will not initiate) any efforts to effect a Public Sale, if
inconsistent with the terms of such Alternate Disposition, until the Alternate
Disposition is closed or terminated without closing. The following types of
transactions or combinations thereof constitute "Alternate Dispositions":

                  (i) A sale or other transfer to any person or persons
            unaffiliated with Grantor for cash.


                                     -12-


                  (ii) A sale or other transfer, conversion or exchange to any
            person or persons unaffiliated with Grantor for any consideration
            other than cash, provided it is not for Restricted Consideration.
            "Restricted Consideration" is an interest in AOL Time Warner or an
            entity that, directly or indirectly, owns interests in cable
            systems or cable programming networks which are attributable under
            then current FCC Regulations to AOL Time Warner.

                  (iii) A sale or other transfer, conversion or exchange to any
            person or persons unaffiliated with Grantor for Restricted
            Consideration.

                  (iv) A transaction: (A) with any person or persons
            unaffiliated with Grantor; (B) which involves a security linked to
            any of the Disposition Property or a security that would be deemed
            to be a "derivative security" (as defined in Rule 16a-1(c) under
            the Securities Exchange Act of 1934, as amended) with respect to
            any of the Disposition Property, or (even if not a security) which
            would (were it a security) be considered such a derivative
            security, or which transfers some or all of the economic risk of
            ownership of any of the Disposition Property, including, without
            limitation, any forward contract, equity swap, put or call, put or
            call equivalent position, collar, non-recourse loan, sale of
            exchangeable security or similar transaction; (C) which has a term
            ending no more than five (5) years following the AT&T Comcast
            Transaction Closing; and (D) pursuant to which the Trust receives
            cash and retains an economic interest equal to no more than 20% of
            the risk of loss or opportunity for gain or an economically
            equivalent combination of risk of loss and opportunity for gain;
            provided, however, that any such transaction shall have economics
            similar to a collar and the spread on the


                                     -13-


           collar shall include the trading price of the relevant Disposition
           Property on the day the transaction is entered into (a "Derivative
           Transaction").

           (d) For the avoidance of doubt, Disposition Property shall, unless
divested by the Trust in accordance with this Section 5, be retained by the
Trust and not distributed to Grantor or its affiliates, except as provided
pursuant to Section 13.

           (e) In the event that all or part of the Disposition Property is
divested in an Alternate Disposition in return for any consideration that does
not constitute Restricted Consideration, the following shall apply: (i) cash
consideration will be distributed to Grantor, in accordance with Section 6; and
(ii) non-cash consideration will remain in the Trust as Disposition Property
unless its distribution to Grantor is approved by the FCC's Media Bureau (the
"Media Bureau"). The Operating Trustee will promptly file a written request
with the Media Bureau, styled as a "Request to Distribute Non-Cash,
Non-Restricted Consideration," seeking approval to distribute any such non-cash
consideration that it receives to Grantor. The distribution of such non-cash
consideration to Grantor shall be deemed approved unless the Media Bureau
notifies the Operating Trustee, in writing and within 30 days of receipt of
such notice from the Operating Trustee, that it objects to such distribution,
provided however, that the Media Bureau may, by written notice to the Operating
Trustee, extend the 30 day period for an additional 30 days if necessary to
complete its review, in which case the distribution will be deemed approved
unless the Media Bureau notifies the Operating Trustee, in writing and within
60 days of its receipt of the Operating Trustee's request, that it objects to
the proposed distribution. If the Media Bureau objects to the distribution of
any non-cash consideration within 30 days of notice from the Operating Trustee
(or, in the event the Media Bureau's review period is extended as provided
herein, within 60 days of the Operating Trustee's notice), then such non-


                                     -14-


cash consideration shall constitute Disposition Property and shall be retained
by the Trust. If at any time after an Alternate Disposition any Restricted
Consideration received in such Alternate Disposition ceases to be Restricted
Consideration, the consideration will be treated as set forth in this Section
5(e) with respect to consideration that is not Restricted Consideration.

           (f) Following an Alternate Disposition, and subject to the
limitations contained in Section 5(g), the Operating Trustee will retain the
power for the remainder of the 5-Year Period to dispose of in a Public Sale any
remaining Disposition Property, other than that which is the subject of a
Derivative Transaction, in a manner intended to maximize the value received by
Grantor, consistent with the goal of concluding a complete divestiture of the
Disposition Property by the end of the 5-Year Period and subject to the
provisions of the Governing Agreements. Following an Alternate Disposition
which is a Derivative Transaction, the Operating Trustee will not take any
action during the 5-Year Period (or, if shorter, during the period of time such
Disposition Property is the subject of the Derivative Transaction) to effect a
Public Sale of that part of the Disposition Property which is the subject of
the Derivative Transaction without the consent of Grantor.

           (g) The Operating Trustee shall take all actions necessary to
implement the TWE Restructuring in accordance with the terms of the TWE
Restructuring Documents, will abide by the TWE Restructuring Documents as if it
were a party thereto and will not take any action that would result in a breach
of the TWE Restructuring Documents by Grantor or any of its affiliates. The
Operating Trustee further agrees that it will dispose of any consideration
received and assets retained in connection with the TWE Restructuring in a
manner consistent with the terms of this Agreement and the TWE Restructuring
Documents; provided that:


                                     -15-


                  (i) The Operating Trustee will not take any action during the
            90-day period following the closing of the TWE Restructuring to
            dispose of any publicly traded common stock of AOL Time Warner held
            by the Trust in a Public Sale, unless so requested by Grantor;

                  (ii) The Operating Trustee will not take any action during
            the 180-day period following the closing of the TWE Restructuring
            to effect any initial public offering of stock in TWC, pursuant to
            any applicable registration rights, unless so requested by Grantor;
            and

                  (iii) If: (A) the consideration received or assets retained
            by the Trust in the TWE Restructuring includes a partnership
            interest in TWE; (B) the TWE Partnership Agreement (as amended and
            restated in connection with the TWE Restructuring) or any other TWE
            Restructuring Document restricts the rights of Grantor or the Trust
            to sell or otherwise transfer such partnership interest for a
            period of time following the closing of the TWE Restructuring not
            to exceed two years; (C) such amended and restated TWE Partnership
            Agreement (or a related agreement) provides procedures for the
            private sale of such partnership interest after such two year
            period; and (D) within three years following the closing of the TWE
            Restructuring Grantor has not elected to have the Trust effect such
            a private sale as an Alternate Disposition; then the Operating
            Trustee shall have the right following such three year period (and
            not prior thereto) to effect such a private sale pursuant to such
            provisions (such a sale of such partnership interest pursuant to
            such provisions, a "Private Sale"). For the avoidance of doubt, the
            term


                                     -16-


            "Private Sale" may include a sale to MOTH or AOL Time Warner
            pursuant to an appraisal process set forth in a TWE Restructuring
            Document.

           (h) Neither Grantor nor any of its affiliates will be permitted to
be a purchaser in a Public Sale or a Private Sale or a counterparty in a
Derivative Transaction.

           (i) If any of the Disposition Property remains at the end of the
5-Year Period, the Operating Trustee will have the authority and be directed to
divest whatever portion of the interest remains as quickly as possible, and in
all events within six (6) months thereafter.

           (j) The Operating Trustee shall not divest all or part of the
Disposition Property until all necessary governmental approvals, if any, have
been received.

      6.   Distribution of Proceeds of Sale; Dividends.

           (a) In the event of any disposition involving all or part of the
Disposition Property, the Operating Trustee shall cause to be distributed to
Grantor as soon as practicable following receipt: (i) any cash; and (ii)
following approval by the Media Bureau pursuant to Section 5(e), any assets
which do not constitute Restricted Consideration. Such amounts may be reduced
by the amount of fees or expense reimbursements then owed by Grantor to the
Trustees.

           (b) In the event that dividends or distributions are paid in respect
of any portion of the Disposition Property, the Operating Trustee shall cause
to be distributed to Grantor as soon as practicable following receipt any such
dividends or distributions to the extent they consist of: (i) any cash; or (ii)
following approval by the Media Bureau pursuant to the procedure described in
Section 5(e), any assets which do not constitute Restricted Consideration.

      7.   Trustee Obligations, Fees and Indemnification.

           (a) The Trust shall be administered by the Operating Trustee in
accordance with the provisions of this Agreement and applicable FCC
Regulations.


                                     -17-


           (b) The Operating Trustee shall maintain such records, files and
books as the Operating Trustee, in the Operating Trustee's reasonable
discretion, deems necessary or appropriate to enable the Operating Trustee to
carry out the terms and conditions of this Agreement and to record the actions
taken by the Operating Trustee in the performance of the Operating Trustee's
duties under this Agreement.

           (c) The Operating Trustee is expressly authorized to incur and
obligate Grantor to pay all charges, taxes and other expenses that are
reasonable, necessary and proper in connection with the preparation, execution
and delivery of this Agreement and the performance by the Operating Trustee of
its duties under this Agreement. Grantor shall pay directly all such charges,
taxes and expenses or reimburse the Operating Trustee therefor within thirty
(30) days after receipt of the Operating Trustee's notice and documentation
under Section 7(e).

           (d) In compensation for the Operating Trustee's services under this
Agreement, Grantor will pay the Operating Trustee customary fees for the time
that the Operating Trustee spends in connection with the formation and
administration of the Trust. All such fees shall become due and payable within
thirty (30) days after the Operating Trustee has given notice thereof to
Grantor under Section 7(e).

           (e) The Operating Trustee shall provide timely and adequate written
notice to Grantor (no more frequently than once each month) specifying in
reasonable detail: (i) the charges, taxes and other expenses to be paid
directly by Grantor to third parties or for which Grantor shall reimburse the
Operating Trustee (together with customary supporting documentation); and (ii)
the fees due to be paid to the Operating Trustee.

           (f) The Operating Trustee shall provide to Grantor: (i) within
fifteen (15) days of receipt thereof, any accountings received by the Operating
Trustee with respect to the


                                     -18-


operations of TWC or any other issuer of securities comprising Disposition
Property, except to the extent disclosure of such information to Grantor is
prohibited by the terms of Section 12; and (ii) within fifteen (15) days of
receipt of a written request by Grantor, an accounting of the expenses of the
Operating Trustee incurred directly or by third parties for the performance of
services to the Operating Trustee in connection with the performance of the
Operating Trustee's duties under this Agreement.

           (g) Except as specifically provided in this Agreement, the Operating
Trustee shall not be entitled to any other fee or other payment hereunder or
otherwise, including any termination fee.

           (h) Grantor hereby agrees to indemnify each Trustee and hold each
Trustee harmless against all claims, actions, proceedings, suits, costs of
defense (including reasonable and customary attorneys' and accountants' fees
and disbursements), expenses, liabilities, judgments, damages, awards and
settlements asserted against or incurred by such Trustee in connection with, or
in any way arising directly or indirectly from, the performance by such Trustee
of its duties under this Agreement, including claims and liabilities arising
from any actions taken by the Operating Trustee in furtherance of its
obligation to sell as quickly as possible any of the Disposition Property that
remains after the 5-Year Period, provided that the indemnification provided for
in this Section 7(h) shall not apply to any claims or liabilities arising from
such Trustee's Malfeasance. For purposes of this Agreement, a Trustee's
"Malfeasance" shall mean such Trustee's bad faith, gross negligence, willful
misconduct or other action inconsistent with the terms of this Agreement or any
of the other Governing Agreements.

           (i) Except as incurred as a result of such Trustee's Malfeasance, a
Trustee shall not be liable with respect to actions taken by it in reliance
upon any paper, document or


                                     -19-


signature reasonably believed by such Trustee to be genuine and to have been
signed by the proper party that is not in fact genuine. A Trustee shall not be
liable for any error of judgment in any act done or omitted, nor for any
mistake of fact or law, nor for anything which such Trustee may do or refrain
from doing in accordance with this Agreement, absent such Trustee's
Malfeasance. A Trustee may consult with accountants, attorneys and other
advisors, and any action taken in accordance with the advice of such advisor
shall be presumptively done in good faith.

           (j) The Operating Trustee shall have no duty or liability to Grantor
with respect to any change in the value of any of the Disposition Property
resulting from TWC's or AOL Time Warner's operations or otherwise (except for
the Operating Trustee's Malfeasance) during the Trust Term.

           (k) Neither Trustee shall be required to furnish a bond or other
security in any jurisdiction for the faithful performance of such Trustee's
duties.

           (l) Except where the provision of Section 5(i) applies, the
Operating Trustee shall manage the property of the Trust, consistent with the
terms of this Agreement, in a manner intended to maximize the value of the
properties of the Trust and Trust I, taken as a whole, and the Trust and Trust
I shall cooperate with each other in connection with any transaction by either
of them.

           (m) The Trustee shall assist Grantor and Grantor's affiliates and
shall cooperate fully in all tax matters relating to the Trust or its assets,
including, without limitation, in connection with the preparation and filing of
any tax returns or reports which Grantor or any of Grantor's affiliates is
required to prepare or file with respect to the Trust or its assets.


                                     -20-


      8. Trustee Selection. The Delaware Trustee, and any successor Delaware
Trustee, shall be either a natural person who is a resident of the State of
Delaware or a legal entity having its principal place of business in the State
of Delaware, in each case appointed by Grantor. The Operating Trustee shall be
appointed by Grantor after approval by the Media Bureau. Each of the Trust and
Trust I shall have the same operating trustee and the same Delaware trustee,
respectively. No Trustee may be a director, officer, manager, agent or employee
of Grantor or its affiliates immediately prior to or at any time while serving
as Trustee, nor may any Trustee have any extratrust business, personal or
familial relationship with Grantor or its affiliates while serving as Trustee
that is inconsistent with any applicable FCC Regulations. In the event that a
Trustee enters into any relationship prohibited by this Section 8 at any time
while serving as Trustee, such Trustee shall resign in the manner provided in
Section 9.

      9.   Trustee Removal, Resignation, and Replacement.

           (a)  Grantor may not remove or replace a Trustee at will.

           (b) The rights and duties of the Trustees hereunder (other than a
Trustee's rights to receive payments to the extent accrued prior to termination
and to be indemnified hereunder) shall terminate upon such Trustee's incapacity
to act, death or bankruptcy or other insolvency. No interest in the Disposition
Property, nor any of the rights and duties of an incapacitated, deceased,
bankrupt or insolvent Trustee, may be transferred by such Trustee by will,
devise, succession or in any other manner except as provided in this Agreement.

           (c) A Trustee may resign by giving thirty (30) days advance written
notice of resignation to Grantor, provided that such Trustee agrees that any
such resignation shall not become effective until a successor Trustee has been
appointed.


                                     -21-


           (d) In the event of a Trustee's resignation, incapacity to act,
death or bankruptcy or other insolvency, such Trustee shall be succeeded by a
successor Trustee chosen by Grantor in compliance with FCC Regulations and the
terms of this Agreement. Any successor Trustee shall succeed to all of the
rights and obligations of the Trustee replaced hereunder upon execution by such
successor Trustee of a counterpart of this Agreement. A successor Trustee shall
not be liable for breaches of this Agreement committed by a predecessor
Trustee.

           (e) Notwithstanding any other provision of this Section 9, a Trustee
that resigns or is removed as trustee of Trust I (other than upon termination
of such trust) shall likewise resign or be removed as Trustee of the Trust.

      10.  Trustee Advisors.

           (a) The Operating Trustee shall have the right to retain such
accountants, attorneys, investment bankers, managing underwriters and other
advisors (collectively, "Advisors") as are necessary or appropriate to enable
the Operating Trustee to perform in a prudent and competent manner the duties
and obligations of the Operating Trustee under this Agreement; provided,
however, that: (i) the fees and expenses of such Advisors shall be reasonable
and customary; and (ii) such Advisors do not have any material business
relationship with AOL Time Warner during the term of the Trust. In order to
facilitate an expeditious divestiture, the Operating Trustee may retain any
Advisors retained prior to the Contribution Date by AT&T, Comcast or their
respective affiliates, provided, however, that: (i) such Advisors are solely
accountable to the Operating Trustee in respect of advice or services rendered
to the Operating Trustee in connection with divestiture of any Disposition
Property; and (ii) such Advisors shall not continue to represent AT&T Comcast
or its affiliates in connection with


                                     -22-


divestiture of such Disposition Property. The Operating Trustee shall be
required to provide Grantor with notice and documentation of fees and expenses
incurred in connection with the retention of Advisors pursuant to this Section
10(a).

           (b) Grantor and its affiliates also shall have the right to retain
Advisors to assist the Operating Trustee's Advisors with the divestiture of the
Disposition Property (including any Advisors retained by AT&T or Comcast prior
to the Contribution Date, to the extent they have not been retained by the
Operating Trustee pursuant to the previous subsection); provided, however, that
the Operating Trustee shall be free to accept or reject any advice offered by
such Advisors and shall be privy to any instructions that Grantor may give to
such Advisors, and provided further, that, for avoidance of doubt, the
Grantor's Advisors may communicate with the Operating Trustee's Advisors, but
shall not communicate directly with the Operating Trustee except in the
presence of Grantor and Operating Trustee's Advisors.

           (c) The Operating Trustee shall direct any Advisors that it retains,
and Grantor shall direct any Advisors that it retains, with regard to the
divestiture of the Disposition Property, to take appropriate steps to ensure
that such Advisors do not act as a conduit for communications between the
Operating Trustee and Grantor that are otherwise prohibited under the terms of
this Agreement.

      11. Grantor Involvement in TWC Management. Except as provided in Section
12(a), Grantor and its affiliates shall not have an interest in, control of or
involvement in the operation or management of TWC, or seek to influence the
operation or management of TWC or any cable system in which TWC has an
interest, other than Kansas City Cable Partners and Texas Cable Partners, L.P.,
on account of AT&T Comcast's 50% general partnership interest therein which is
held outside of TWC, provided that Grantor and its affiliates shall not: (i)
receive information


                                     -23-


from Kansas City Cable Partners or Texas Cable Partners, L.P. regarding the
price, terms or conditions that TWC, or any affiliate of AOL Time Warner that
is a successor to TWC's interest in Kansas City Cable Partners or Texas Cable
Partners, L.P. or any of TWC's or such successor's affiliates (other than
Kansas City Cable Partners or Texas Cable Partners, L.P. or any of their
subsidiaries), negotiates for carriage of video programming on the cable
systems owned by Kansas City Cable Partners or Texas Cable Partners, L.P.; or
(ii) provide information to Kansas City Cable Partners or Texas Cable Partners,
L.P. regarding the price, terms or conditions that Grantor or its affiliates
negotiate for the carriage of video programming on the cable systems owned by
Grantor or its affiliates. For purposes of this Section 11, the term "TWC"
shall include TWC and any other issuer of securities or ownership interests
constituting Disposition Property. This Section 11 will cease to apply with
respect to Kansas City Cable Partners or Texas Cable Partners, L.P., as the
case may be, at such time as neither TWC nor any other affiliate of AOL Time
Warner owns any interest in such entity.

      12.  Communications.

           (a)  Communications Regarding Operation and Management of TWC.

                  (i) The Operating Trustee shall not provide any information
            to Grantor concerning the operation or management of TWC or the
            operation or management of the cable systems in which TWC has a
            direct or indirect interest, except that the Operating Trustee
            shall use its reasonable best efforts to obtain and provide Grantor
            with financial statements and tax information with respect to TWC
            and the Disposition Property as and when furnished by TWC and as
            required by Grantor or its affiliates for compliance with
            securities and tax laws, rules and regulations, or other applicable
            legal or regulatory requirements. None


                                     -24-


            of Grantor, or any of its affiliates, or any of its or their
            officers, directors or employees, shall communicate with the
            Operating Trustee, directly or indirectly, including indirectly
            through their Advisors, regarding the operation or management of
            TWC or the operation or management of any cable system in which TWC
            has an interest.

                  (ii) The Operating Trustee shall have such access to Grantor
            and its affiliates' personnel, books, records and facilities
            related to the Disposition Property as may be reasonably necessary
            for the Operating Trustee to fulfill its obligations hereunder.

                  (iii) Any communications between the Operating Trusteee and
            Grantor or its affiliates permitted by this subsection (a) shall be
            in writing.

            (b) Communications Regarding Public Sale, Private Sale or Alternate
Disposition. The Operating Trustee and Grantor and its affiliates may engage in
communications in order to facilitate divestiture of the Disposition Property
through any Public Sale, Private Sale or Alternate Disposition. The Operating
Trustee shall provide periodic reports (no less frequently than quarterly
during the 5-Year Period and no less frequently than monthly thereafter) to
Grantor (with a copy to the Media Bureau) describing the Operating Trustee's
efforts to accomplish divestiture of the Disposition Property through any
Public Sale, Private Sale or Alternate Disposition, provided, however, that to
the extent such reports contain information that Grantor deems confidential,
such reports shall be provided to the Media Bureau only after such confidential
information has been redacted. In the event that such reports are provided to
the Media Bureau in redacted form, the unredacted versions of such reports will
be maintained by the Operating Trustee, or its designee, at a location in the
Washington, D.C. area,


                                     -25-


and shall be made available upon request for inspection by the Media Bureau
during normal business hours. Upon request by the Media Bureau, the Operating
Trustee shall file the unredacted version of any such report with the Media
Bureau accompanied by a request for confidential treatment. Grantor will use
its reasonable best efforts, consistent with the terms of this Agreement and
applicable FCC Regulations, to assist the Operating Trustee in accomplishing
the divestiture of the Disposition Property, including using its reasonable
best efforts to provide such information as is required by the Operating
Trustee to effect such divestiture.

           (c) Communications Regarding Fiduciary Matters. Communications
between the Trustees and Grantor regarding the fiduciary obligations owed by
the Trustees to Grantor shall be permitted at any time.

           (d) The Operating Trustee shall retain copies of all written
communications between the Operating Trustee or its Advisors and Grantor, its
affiliates or its Advisors. The Operating Trustee shall prepare (or, as
appropriate, instruct its Advisors to prepare) and retain a contemporaneous
written summary of all oral communications between the Operating Trustee or its
Advisors and Grantor, its affiliates or its Advisors, pursuant to subsections
(b) and (c) of this Section 12, provided that such summary shall not be
required for oral communications that are ministerial or non-substantive in
nature, or are otherwise not material to the performance of the Operating
Trustee's fiduciary obligations to Grantor or its efforts to (a) divest the
Disposition Property or (b) effect an Alternate Disposition in accordance with
the terms of this Agreement. All written communications and summaries of oral
communications shall be maintained by the Operating Trustee, or its designee,
at a location in the Washington, D.C. area, and shall be made available upon
request for inspection by the Media Bureau during normal business hours.


                                     -26-


           (e) Subject to a customary confidentiality agreement and to the
terms of any other agreement to which the Trust is a party or otherwise
subject, the Operating Trustee shall permit prospective purchasers of the
Disposition Property in an Alternate Disposition (at the request of the
Grantor) or a Private Sale (at the Operating Trustee's discretion)] to have
access to any and all financial or operational information to which the
Operating Trustee has access, as may be relevant to divestiture of the
Disposition Property.

      13.  Termination.

           (a) Subject to the provisions of Section 17(e), the Trust shall
dissolve upon written election by Grantor delivered to the Trustees, provided
that one of the following events has occurred (any such event, a "Dissolution
Event"):

                  (i) divestiture of all of the Disposition Property and the

            such divestiture, in the manner provided in Sections 5(e) and 6(a);

                  (ii) expiration of the six-month period following the 5-Year
            Period, provided, however, that if any portion of the Disposition
            Property remains in the Trust at the expiration of the six-month
            period following the 5-Year Period, the Trust will continue until
            the FCC either approves the dissolution of the Trust or the
            remainder of the Disposition Property has been divested and all
            proceeds due


                                     -28-


           to the order of Grantor with respect to such divestiture have been
           paid, in the manner provided in Sections 5(e) and 6(a); or

                 (iii) AT&T Comcast ceases directly or indirectly to own any
           beneficial interest in the Trust.

           (b) Upon dissolution of the Trust, the Operating Trustee shall take
such action as is necessary or appropriate to deliver to the order of Grantor,
or such other party designated by Grantor in writing to the Operating Trustee,
all property then held by the Trust or the Operating Trustee on behalf of the
Trust pursuant to this Agreement, subject to satisfaction (whether by payment
or reasonable provision therefor) of claims of all creditors of the Trust
(other than Grantor) including, without limitation, the Trustees. The Operating
Trustee shall have a reasonable period to conclude the administration of the
Trust, and shall be compensated for all reasonably necessary services performed
after the dissolution date. Following completion by the Operating Trustee of
the actions required by this Section 13(b), the Operating Trustee shall provide
written notice to Grantor and, upon written request of Grantor, the Trustees
shall terminate the legal existence of the Trust by canceling the Certificate
of Trust in accordance with the Act.

           (c) Notwithstanding any other provision of this Section 13, upon a
Dissolution Event, Grantor may elect, in lieu of dissolving the Trust, to
terminate this Agreement and to convert the Trust into a Delaware limited
liability company, Delaware corporation or other legal entity, which conversion
shall be upon such terms as Grantor shall deem appropriate; provided that upon
completion of such conversion all rights, obligations, assets and liabilities
of the Trust remain, under applicable law, rights, obligations, assets and
liabilities of the entity so created. The Trustees shall cooperate with Grantor
in connection with the foregoing.


                                     -29-


           (d) At any time, subject to the Governing Agreements, Grantor may
cause the Trustees to merge the Trust with Trust I, or to transfer all of the
assets and liabilities of the Trust (including, without limitation, the
Disposition Property) to Trust I, or to accept a transfer of all of the assets
and liabilities of Trust I to the Trust; provided that, in each case and to the
extent required under the Governing Agreements, the successor or transferee
trust shall assume the obligations of the merged or transferor trust under the
Governing Agreements (other than the Declaration of Trust of the merged or
transferor trust). For purposes of this Section 13(d), the term "Governing
Agreements" includes the "Governing Agreements" as defined in this Agreement
and in the Declaration of Trust of the successor or transferee, or merged or
transferor, trust, as the case may be.

      14. Modification. This Agreement shall not be modified except by an
instrument in writing executed by Grantor and the Operating Trustee; provided
that the rights, duties, responsibilities and compensation of the Delaware
Trustee shall not be changed without the prior written consent of the Delaware
Trustee. No modifications of this Agreement, except for modifications that are
insubstantial and immaterial, shall be made unless approved by the Media
Bureau. A request for approval of a modification of this Agreement shall be
deemed approved unless the Media Bureau notifies the Operating Trustee, in
writing and within 14 days of receipt of such request from the Operating
Trustee, that it objects to such modification. A copy of any insubstantial and
immaterial modification in the Trust shall be filed with the FCC within ten
days following the execution thereof, with a copy to the Media Bureau. The
parties shall cooperate in the modification of this Agreement in the event
changes or modifications are needed in order to bring this Agreement and the
transactions contemplated hereby into compliance with applicable FCC
Regulations or other applicable laws.


                                     -30-


      15. Assignment. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their respective permitted successors and
permitted assigns. Subject to the power to delegate the performance of
ministerial responsibilities hereunder as deemed necessary by the Operating
Trustee, this Agreement shall not be assignable by the Trustees. Grantor shall
be entitled to assign its rights hereunder to AT&T Comcast or any subsidiary
thereof or any person who becomes the direct or indirect beneficial owner of
the Disposition Property as a result of a merger or transfer of all or
substantially all the assets of AT&T Comcast or any of its subsidiaries.

      16. Confidentiality. This Agreement and all matters concerning the
performance, enforcement and interpretation hereof shall be kept in strict
confidence by the parties, except where disclosure is required by law, rule or
regulation (including the Federal securities laws or FCC Regulations), to carry
out the express purposes and terms of this Agreement, or in connection with any
claims or actions relating to this Agreement.

      17.  Miscellaneous.

           (a) If any part of any provision of this Agreement or any other
agreement, document or writing given pursuant to or in connection with this
Agreement shall be invalid or unenforceable under applicable law, said part
shall be ineffective to the extent of such invalidity only, without in any way
affecting the remaining part of said provision or the remaining provisions of
this Agreement.

           (b) The headings of the sections and subsections of this Agreement
are inserted for convenience of reference only and do not form a part or affect
the meaning hereof.


                                     -31-


           (c) This Agreement, the rights and obligations of the parties
hereto, and any claims and disputes relating thereto, shall be governed by and
construed in accordance with the laws of the State of Delaware (not including
the choice of law rules thereof).

           (d) This Agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original, and all of which together
shall be deemed to be one and the same instrument.

           (e) The provisions of Sections 7, 12(f), 14, 15, 16 and 17 shall
remain in effect, and shall survive, any termination of the Trust.

           (f) The failure of Grantor or a Trustee to exercise or enforce any
right or provision of this Agreement shall not constitute a waiver of such
right or provision.

           (g) This Agreement, together with the Certificate of Trust, is the
complete and exclusive agreement between the parties with respect to the
creation, operation and termination of the Trust, superseding and replacing any
and all prior agreements, communications and understandings, written or oral,
regarding such Trust.

           (h) Neither Trustee shall have any duty or other obligation to pay,
provide or arrange for the provision of funds necessary to perform such
Trustee's duties under this Agreement, other than the provision of the written
notices to Grantor pursuant to Section 7 hereof. Neither Trustee shall have any
personal liability for the payment of any Trust expense or obligation to third
parties whatsoever.


                                     -32-

      WHEREAS, the parties hereto now wish to establish the terms and
conditions under which the Trust will be administered in order to effect
divestiture of the Disposition Property (as defined in Section 4); and

      WHEREAS, Edith E. Holiday wishes to serve as Operating
Trustee of the Trust.

      NOW, THEREFORE, in consideration of the foregoing and mutual covenants
and agreements hereinafter set forth, the parties hereto agree as follows:

      1.   General Provisions.

           (a) Name. The name of this trust is "TWE Holdings III Trust." The
Trust's business may be conducted under the name of the Trust or any other name
or names selected by the Operating Trustee.

           (b) Principal Office. The principal office of the Trust shall be 801
West Street, 2nd Floor, Wilmington, Delaware 19801, or such other place within
the State of Delaware as may from time to time be designated by the Operating
Trustee, provided, however, that the Operating Trustee shall not locate its
offices at the offices of AT&T Comcast or its affiliates, as


                                      -5-


defined below. The Operating Trustee shall give prompt notice of any change in
the address of its principal office to Grantor and the Delaware Trustee.
Neither the Delaware Trustee nor the Operating Trustee shall maintain an office
outside of the State of Delaware for the conduct of the business of the Trust
or conduct the business of the Trust outside of the State of Delaware; provided
that the Operating Trustee may from time to time conduct the business of the
Trust outside of the State of Delaware if reasonably required for the conduct
of such business. The Operating Trustee shall comply with such conditions
relating to the immediately preceding sentence as Grantor shall reasonably
request.

           (c) Delaware Trustee. The address of the Delaware Trustee in
Delaware is One Little Falls Centre I, Suite 210, 2711 Centreville Road,
Wilmington, Delaware 19808. The Delaware Trustee is appointed to serve as the
trustee of the Trust in Delaware for the sole purpose of satisfying the
requirements of Section 3807 of the Act that the Trust have at least one
trustee with a principal place of business in Delaware. The Delaware Trustee
shall be entitled to receive customary fees for its services. It is understood
and agreed by the parties hereto that the Delaware Trustee shall have none of
the rights, duties or liabilities of the Operating Trustee. The rights and
duties of the Delaware Trustee shall be limited to (a) accepting legal process
served on the Trust in Delaware and (b) the execution of any certificates
required to be filed with the Delaware Secretary of State which the Delaware
Trustee is required to execute under Section 3811 of the Act. To the extent
that, at law or in equity, the Delaware Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or Grantor, it is hereby
understood and agreed by the parties hereto, including Grantor, that such
duties and liabilities are replaced by the duties and liabilities of the
Delaware Trustee expressly set forth in this


                                      -6-


Agreement. The Delaware Trustee and the Operating Trustee are referred to
herein collectively as the "Trustees" and each individually as a "Trustee."

           (d) Declaration of Trust. The Delaware Trustee and the Operating
Trustee each hereby declares that it will hold the assets of the Trust in trust
upon and subject to the conditions set forth herein for the benefit of Grantor,
the holder of 100% of the beneficial interests in the Trust, and in compliance
with all applicable rules, regulations and orders of the Federal Communications
Commission ("FCC Regulations"). It is the intention of the parties hereto that
the Trust be a statutory trust under the Act. The Delaware Trustee and the
Operating Trustee are hereby authorized to execute any amendment or restatement
of the Certificate of Trust so long as such amendment or restatement is not
inconsistent with the provisions hereof. The Trust is not intended to be, shall
not be deemed to be, and shall not be treated as, a general partnership,
limited partnership, joint venture, corporation or joint stock company.

           (e) No Individual Ownership. Title to all of the assets of the Trust
shall be vested in the Trust until the Trust dissolves or is converted in
accordance with Section 13 hereof; provided, however, if the applicable laws of
any jurisdiction require that title to any part of the assets of the Trust be
vested in a trustee of the Trust, then title to that part of the assets of the
Trust shall be vested in the Operating Trustee to the extent so required, but
the beneficial interest with respect to such asset shall remain in the Trust
for the benefit of the Trust beneficiaries.

           (f) Tax Treatment. The parties hereby agree that the Trust shall be
treated as a "grantor trust" or, in the event the Trust shall be engaged in the
conduct of a business for profit, as a business entity that is disregarded as
separate from Grantor for purposes of the U.S. Federal, state and local tax
laws, and further agree: (i) not to take any position (or cause the Trust to do


                                      -7-


so), in a tax return or otherwise, or take any other action, that is
inconsistent with such treatment; and (ii) to take all commercially reasonable
actions necessary to cause the Trust to be so treated.

      2.   Contribution to the Trust.

           (a) The date on which the MOTH TWE Contribution and the Trust 3
Conversion were completed is referred to in this Agreement as the "Contribution
Date".

           (b) Following the Contribution Date and during the Trust Term (as
defined in Section 3), except as otherwise provided by this Agreement, the
Trust shall have legal and record ownership of the MOTH TWE Interest and all
other assets constituting Disposition Property (as defined in Section 4).

           (c) Grantor represents and warrants to the Operating Trustee that:
(i) the MOTH TWE Contribution was effected in accordance with applicable FCC
Regulations; (ii) as of the Contribution Date, Grantor had full right and legal
authority to effect the MOTH TWE Contribution as described herein; (iii) as of
the Contribution Date, the MOTH TWE Interest was not subject to any liens or
other encumbrances (other than as created by, or permitted under, this
Agreement, the TWE Restructuring Documents or the TWE Partnership Agreement);
and (iv) all consents, waivers and approvals of the Federal Communications
Commission ("FCC") and third parties necessary for the MOTH TWE Contribution
have been received and are in full force and effect.

           (d) If any additional interest in TWE is acquired by AT&T Comcast or
any of its subsidiaries during the Trust Term, AT&T Comcast shall cause such
interest to be contributed to the Trust and become property of the Trust or, if
AT&T Comcast so elects, AT&T Comcast may cause such additional interest to be
contributed to, and become property of, Trust I. Except


                                      -8-


as provided herein, no other property may be contributed to the Trust by any
party without the prior written agreement of the Operating Trustee.

      3. Term of the Trust and Irrevocability. The Trust shall be irrevocable
by Grantor and shall have a term that expires at such time as the Trust
terminates in accordance with the provisions of Section 13 (the "Trust Term").

      4. Operating Trustee Control of the Disposition Property. The Operating
Trustee shall have sole and exclusive authority to manage: (a) the MOTH TWE
Interest; (b) any additional TWE interest subsequently contributed to the
Trust; (c) any Restricted Consideration (as defined in Section 5(c)) received
by the Trust; and (d) any other non-cash consideration received by the Trust in
an Alternate Disposition (as defined in Section 5(c)) or as a dividend or
distribution on securities or ownership interests held by the Trust and not
approved by the Media Bureau (as defined in Section 5(e)) for distribution to
Grantor in accordance with Section 5(e) or 6(b), respectively, (such TWE
interests, Restricted Consideration and other non-cash assets received by the
Trust and not approved for distribution, collectively, the "Disposition
Property"), and to exercise any and all rights with respect to any Disposition
Property including, without limitation, the MOTH Assumed Rights and the right
to exercise any voting, director appointment, consent, approval or management
rights arising from the Disposition Property under the TWE Partnership
Agreement, in a manner intended to maximize the value of the Disposition
Property. Without limiting the foregoing, Grantor or its affiliates will, upon
or prior to the Closing, cause the representatives appointed by Grantor (or any
of its affiliates) to the TWE board of representatives to resign and,
subsequent to such resignations, the Operating Trustee will exercise any right
to appoint replacement representatives when, in the Operating Trustee's
judgment, doing so is necessary to protect the value of any Disposition
Property.


                                      -9-


Grantor shall not retain any voting, director appointment, consent, approval or
management rights with respect to the Disposition Property. Grantor shall not
have any rights to require the Operating Trustee to consult with Grantor or its
affiliates with respect to the exercise of such rights and the Operating
Trustee shall not consult with Grantor with respect to such rights. As used
herein, the term "affiliates" shall have the definition adopted in 47 U.S.C.
ss. 153(1) provided however, that for purposes of this Agreement neither the
Trust nor any of its subsidiaries shall be deemed to be an affiliate of Grantor
or of any of Grantor's affiliates. The Trust shall retain and hold, and the
Operating Trustee shall manage, the Disposition Property in accordance with,
and subject to, the terms and conditions set forth in this Agreement, the TWE
Partnership Agreement, the TWE Restructuring Documents to the extent the Trust
is a party thereto or is otherwise bound thereby, and any other applicable
constitutional document or other agreement setting out rights and
responsibilities with respect to any Disposition Property entered into in
connection with an Alternate Disposition or Public Sale (collectively, the
"Governing Agreements"). The Operating Trustee shall have the authority to
sell, transfer, assign, pledge or otherwise dispose of or encumber the
Disposition Property only to the extent and in the manner provided in the
Governing Agreements. The Operating Trustee shall cause the Trust to comply
with the applicable terms of the Governing Agreements.

      5.   Divestiture of the Disposition Property.

           (a) The Operating Trustee shall, in accordance with the terms of
this Agreement, divest the Disposition Property. Subject to compliance by the
Operating Trustee with its obligations under this Agreement, the decision to
divest part or all of the Disposition Property shall be made by the Operating
Trustee in its sole discretion. Subject to Section 5(c),


                                     -10-


Grantor shall not take any action to block a sale by the Operating Trustee on
any grounds other than the Operating Trustee's Malfeasance (as defined in
Section 7(h)).

           (b) During the period commencing with the Closing and ending five
(5) years thereafter (the "5-Year Period"), except as otherwise provided
herein, the Operating Trustee shall pursue such registration rights as are
available with respect to all or any portion of the Disposition Property
pursuant to the TWE Partnership Agreement, the TWE Restructuring Documents or
otherwise, in a manner intended to maximize the value received by Grantor,
consistent with the goal of concluding a complete divestiture of the
Disposition Property by the end of the 5-Year Period. The Operating Trustee
shall have complete authority to prosecute such registration rights, including
authority to engage in such litigation as may be necessary. In addition, if any
of the Disposition Property is saleable in the public market either under an
already effective registration statement or without the requirement of a
registration statement under Federal or state securities laws, then the
Operating Trustee may also seek to effect a sale pursuant thereto in a manner
intended to maximize the value received by Grantor, consistent with the goal of
concluding a complete divestiture of the Disposition Property by the end of the
5-Year Period. A sale by the Operating Trustee in the manner permitted in this
Section 5(b) is referred to herein as a "Public Sale." The Operating Trustee
shall not otherwise have the power to dispose of any of the Disposition
Property during the 5-Year Period, except pursuant to one or more Alternate
Dispositions, or as provided in Section 13.

           (c) Notwithstanding the foregoing, at any time during the 5-Year
Period, Grantor may propose any one or more Alternate Dispositions (as defined
below) with respect to all or part of the Disposition Property, which the
Operating Trustee shall be obligated to use reasonable best efforts to cause
the Trust to effect (including by becoming a party to agreements


                                     -11-


related thereto, subject to appropriate indemnification from Grantor and its
affiliates), unless such Alternate Disposition is withdrawn by Grantor. If
necessary to effect an Alternate Disposition, the Operating Trustee will
discontinue (and will not initiate) any efforts to effect a Public Sale, if
inconsistent with the terms of such Alternate Disposition, until the Alternate
Disposition is closed or terminated without closing. The following types of
transactions or combinations thereof constitute "Alternate Dispositions":

                  (i) A sale or other transfer to any person or persons
            unaffiliated with Grantor for cash.

                  (ii) A sale or other transfer, conversion or exchange to any
            person or persons unaffiliated with Grantor for any consideration
            other than cash, provided it is not for Restricted Consideration.
            "Restricted Consideration" is an interest in AOL Time Warner or an
            entity that, directly or indirectly, owns interests in cable
            systems or cable programming networks which are attributable under
            then current FCC Regulations to AOL Time Warner.

                  (iii) A sale or other transfer, conversion or exchange to any
            person or persons unaffiliated with Grantor for Restricted
            Consideration. For the avoidance of doubt, the conversion of TWE to
            a corporation in connection with the registration rights process
            under the TWE Partnership Agreement, and the TWE Restructuring,
            each would be deemed to be an Alternate Disposition for Restricted
            Consideration.

                  (iv) A transaction: (A) with any person or persons
            unaffiliated with Grantor; (B) which involves a security linked to
            any of the Disposition Property or a security that would be deemed
            to be a "derivative security" (as defined in


                                     -12-


           Rule 16a-1(c) under the Securities Exchange Act of 1934, as
           amended) with respect to any of the Disposition Property, or (even
           if not a security) which would (were it a security) be considered
           such a derivative security, or which transfers some or all of the
           economic risk of ownership of any of the Disposition Property,
           including, without limitation, any forward contract, equity swap,
           put or call, put or call equivalent position, collar, non-recourse
           loan, sale of exchangeable security or similar transaction; (C)
           which has a term ending no more than five (5) years following the
           Closing; and (D) pursuant to which the Trust receives cash and
           retains an economic interest equal to no more than 20% of the risk
           of loss or opportunity for gain or an economically equivalent
           combination of risk of loss and opportunity for gain; provided,
           however, that any such transaction shall have economics similar to
           a collar and the spread on the collar shall include the trading
           price of the relevant Disposition Property on the day the
           transaction is entered into (a "Derivative Transaction").

           (d) For the avoidance of doubt, Disposition Property shall, unless
divested by the Trust in accordance with this Section 5, be retained by the
Trust and not distributed to Grantor or its affiliates, except as provided
pursuant to Section 13.

           (e) In the event that all or part of the Disposition Property is
divested in an Alternate Disposition in return for any consideration that does
not constitute Restricted Consideration, the following shall apply: (i) cash
consideration will be distributed to Grantor, in accordance with Section 6; and
(ii) non-cash consideration will remain in the Trust as Disposition Property
unless its distribution to Grantor is approved by the FCC's Media Bureau (the
"Media Bureau"). The Operating Trustee will promptly file a written request
with the


                                     -13-


Media Bureau, styled as a "Request to Distribute Non-Cash, Non-Restricted
Consideration," seeking approval to distribute any such non-cash consideration
that it receives to Grantor. The distribution of such non-cash consideration to
Grantor shall be deemed approved unless the Media Bureau notifies the Operating
Trustee, in writing and within 30 days of receipt of such notice from the
Operating Trustee, that it objects to such distribution, provided however, that
the Media Bureau may, by written notice to the Operating Trustee, extend the 30
day period for an additional 30 days if necessary to complete its review, in
which case the distribution will be deemed approved unless the Media Bureau
notifies the Operating Trustee, in writing and within 60 days of its receipt of
the Operating Trustee's request, that it objects to the proposed distribution.
If the Media Bureau objects to the distribution of any non-cash consideration
within 30 days of notice from the Operating Trustee (or, in the event the Media
Bureau's review period is extended as provided herein, within 60 days of the
Operating Trustee's notice), then such non-cash consideration shall constitute
Disposition Property and shall be retained by the Trust. If at any time after
an Alternate Disposition any Restricted Consideration received in such
Alternate Disposition ceases to be Restricted Consideration, the consideration
will be treated as set forth in this Section 5(e) with respect to consideration
that is not Restricted Consideration.

           (f) Following an Alternate Disposition, and subject to the
limitations contained in Section 5(g), the Operating Trustee will retain the
power for the remainder of the 5-Year Period to dispose of in a Public Sale any
remaining Disposition Property, other than that which is the subject of a
Derivative Transaction, in a manner intended to maximize the value received by
Grantor, consistent with the goal of concluding a complete divestiture of the
Disposition Property by the end of the 5-Year Period and subject to the
provisions of the Governing Agreements. Following an Alternate Disposition
which is a Derivative Transaction,


                                     -14-


the Operating Trustee will not take any action during the 5-Year Period (or, if
shorter, during the period of time such Disposition Property is the subject of
the Derivative Transaction) to effect a Public Sale of that part of the
Disposition Property which is the subject of the Derivative Transaction without
the consent of Grantor.

           (g) The Operating Trustee acknowledges that the registration rights
process currently provided for in the TWE Partnership Agreement has been
suspended. Grantor represents to the Operating Trustee that the Restructuring
Agreement provides that in the event of termination of the Restructuring
Agreement, the registration rights process in effect at the time of the
execution of the Restructuring Agreement will be reinstated at the same point
at which it was suspended (with the general rule being that the appraisal
previously completed in connection with such process shall be prepared again
and, in the event the investment banking firm that conducted such earlier
appraisal is not at such time eligible to be engaged, a new investment banking
firm will have to be selected and engaged, provided that in certain exceptional
circumstances the existing appraisal may be used). The Operating Trustee shall
take all actions necessary to implement the TWE Restructuring in accordance
with the terms of the TWE Restructuring Documents, will abide by the TWE
Restructuring Documents as if it were a party thereto and will not take any
action that would result in a breach of the TWE Restructuring Documents by
Grantor or any of its affiliates.

           (h) Neither Grantor nor any of its affiliates will be permitted to
be a purchaser in a Public Sale or a counterparty in a Derivative Transaction.

           (i) If any of the Disposition Property remains at the end of the
5-Year Period, the Operating Trustee will have the authority and be directed to
divest whatever portion of the interest remains as quickly as possible, and in

           (b) In the event that dividends or distributions are paid in respect
of any portion of the Disposition Property, the Operating Trustee shall cause

discretion, deems necessary or appropriate to enable the Operating Trustee to
carry out the terms and conditions of this Agreement and to record the actions

duties under this Agreement.

           (c) The Operating Trustee is expressly authorized to incur and
obligate Grantor to pay all charges, taxes and other expenses that are
reasonable, necessary and proper in


                                     -16-


connection with the preparation, execution and delivery of this Agreement and
the performance by the Operating Trustee of its duties under this Agreement.
Grantor shall pay directly all such charges, taxes and expenses or reimburse
the Operating Trustee therefor within thirty (30) days after receipt of the
Operating Trustee's notice and documentation under Section 7(e).

           (d) In compensation for the Operating Trustee's services under this
Agreement, Grantor will pay the Operating Trustee customary fees for the time
that the Operating Trustee spends in connection with the formation and
administration of the Trust. All such fees shall become due and payable within
thirty (30) days after the Operating Trustee has given notice thereof to
Grantor under Section 7(e).

           (e) The Operating Trustee shall provide timely and adequate written
notice to Grantor (no more frequently than once each month) specifying in
reasonable detail: (i) the charges, taxes and other expenses to be paid

within fifteen (15) days of receipt of a written request by Grantor, an

                                     -17-


           (g) Except as specifically provided in this Agreement, the Operating
Trustee shall not be entitled to any other fee or other payment hereunder or
otherwise, including any termination fee.

           (h) Grantor hereby agrees to indemnify each Trustee and hold each
Trustee harmless against all claims, actions, proceedings, suits, costs of
defense (including reasonable and customary attorneys' and accountants' fees
and disbursements), expenses, liabilities, judgments, damages, awards and
settlements asserted against or incurred by such Trustee in connection with, or
in any way arising directly or indirectly from, the performance by such Trustee
of its duties under this Agreement, including claims and liabilities arising
from any actions taken by the Operating Trustee in furtherance of its
obligation to sell as quickly as possible any of the Disposition Property that
remains after the 5-Year Period, provided that the indemnification provided for
in this Section 7(h) shall not apply to any claims or liabilities arising from
such Trustee's Malfeasance. For purposes of this Agreement, a Trustee's
"Malfeasance" shall mean such Trustee's bad faith, gross negligence, willful
misconduct or other action inconsistent with the terms of this Agreement or any
of the other Governing Agreements.

           (i) Except as incurred as a result of such Trustee's Malfeasance, a
Trustee shall not be liable with respect to actions taken by it in reliance
upon any paper, document or signature reasonably believed by such Trustee to be
genuine and to have been signed by the proper party that is not in fact
genuine. A Trustee shall not be liable for any error of judgment in any act
done or omitted, nor for any mistake of fact or law, nor for anything which
such Trustee may do or refrain from doing in accordance with this Agreement,
absent such Trustee's Malfeasance. A Trustee may consult with accountants,
attorneys and other advisors, and any


                                     -18-


action taken in accordance with the advice of such advisor shall be
presumptively done in good faith.

           (j) The Operating Trustee shall have no duty or liability to Grantor
with respect to any change in the value of any of the Disposition Property
resulting from TWE's operations or otherwise (except for the Operating
Trustee's Malfeasance) during the Trust Term.

           (k) Neither Trustee shall be required to furnish a bond or other
security in any jurisdiction for the faithful performance of such Trustee's
duties.

           (l) Except where the provision of Section 5(i) applies, the
Operating Trustee shall manage the property of the Trust, consistent with the
terms of this Agreement, in a manner intended to maximize the value of the
properties of the Trust and Trust I, taken as a whole, and the Trust and Trust
I shall cooperate with each other in connection with any transaction by either
of them.

           (m) The Trustee shall assist Grantor and Grantor's affiliates and
shall cooperate fully in all tax matters relating to the Trust or its assets,
including, without limitation, in connection with the preparation and filing of
any tax returns or reports which Grantor or any of Grantor's affiliates is
required to prepare or file with respect to the Trust or its assets.

      8. Trustee Selection. The Delaware Trustee, and any successor Delaware
Trustee, shall be either a natural person who is a resident of the State of
Delaware or a legal entity having its principal place of business in the State
of Delaware, in each case appointed by Grantor. The Operating Trustee shall be
appointed by Grantor after approval by the Media Bureau. Each of the Trust and
Trust I shall have the same operating trustee and the same Delaware trustee,
respectively. No Trustee may be a director, officer, manager, agent or employee
of Grantor or its affiliates immediately prior to or at any time while serving
as Trustee, nor may any Trustee have


                                     -19-


any extratrust business, personal or familial relationship with Grantor or its
affiliates while serving as Trustee that is inconsistent with any applicable
FCC Regulations. In the event that a Trustee enters into any relationship
prohibited by this Section 8 at any time while serving as Trustee, such Trustee
shall resign in the manner provided in Section 9.

      9.   Trustee Removal, Resignation, and Replacement.

           (a)  Grantor may not remove or replace a Trustee at will.

           (b) The rights and duties of the Trustees hereunder (other than a
Trustee's rights to receive payments to the extent accrued prior to termination
and to be indemnified hereunder) shall terminate upon such Trustee's incapacity
to act, death or bankruptcy or other insolvency. No interest in the Disposition
Property, nor any of the rights and duties of an incapacitated, deceased,
bankrupt or insolvent Trustee, may be transferred by such Trustee by will,
devise, succession or in any other manner except as provided in this Agreement.

           (c) A Trustee may resign by giving thirty (30) days advance written
notice of resignation to Grantor, provided that such Trustee agrees that any
such resignation shall not become effective until a successor Trustee has been
appointed.

           (d) In the event of a Trustee's resignation, incapacity to act,
death or bankruptcy or other insolvency, such Trustee shall be succeeded by a
successor Trustee chosen by Grantor in compliance with FCC Regulations and the
terms of this Agreement. Any successor Trustee shall succeed to all of the
rights and obligations of the Trustee replaced hereunder upon execution by such
successor Trustee of a counterpart of this Agreement. A successor Trustee shall
not be liable for breaches of this Agreement committed by a predecessor
Trustee.


                                     -20-


           (e) Notwithstanding any other provision of this Section 9, a Trustee
that resigns or is removed as trustee of Trust I (other than upon termination
of such trust) shall likewise resign or be removed as Trustee of the Trust.

      10.  Trustee Advisors.

           (a) The Operating Trustee shall have the right to retain such
accountants, attorneys, investment bankers, managing underwriters and other
advisors (collectively, "Advisors") as are necessary or appropriate to enable
the Operating Trustee to perform in a prudent and competent manner the duties
and obligations of the Operating Trustee under this Agreement; provided,
however, that: (i) the fees and expenses of such Advisors shall be reasonable
and customary; and (ii) such Advisors do not have any material business
relationship with AOL Time Warner during the term of the Trust. In order to
facilitate an expeditious divestiture, the Operating Trustee may retain any
Advisors retained prior to the Contribution Date by AT&T, Comcast or their
respective affiliates, provided, however, that: (i) such Advisors are solely
accountable to the Operating Trustee in respect of advice or services rendered
to the Operating Trustee in connection with divestiture of any Disposition
Property; and (ii) such Advisors shall not continue to represent AT&T Comcast
or its affiliates in connection with divestiture of such Disposition Property.
The Operating Trustee shall be required to provide Grantor with notice and
documentation of fees and expenses incurred in connection with the retention of
Advisors pursuant to this Section 10(a).

           (b) Grantor and its affiliates also shall have the right to retain
Advisors to assist the Operating Trustee's Advisors with the divestiture of the
Disposition Property (including any Advisors retained by AT&T or Comcast prior
to the Contribution Date, to the extent they have not been retained by the
Operating Trustee pursuant to the previous subsection);


                                     -21-


provided, however, that the Operating Trustee shall be free to accept or reject
any advice offered by such Advisors and shall be privy to any instructions that
Grantor may give to such Advisors, and provided further, that, for avoidance of
doubt, the Grantor's Advisors may communicate with the Operating Trustee's
Advisors, but shall not communicate directly with the Operating Trustee except
in the presence of Grantor and Operating Trustee's Advisors.

           (c) The Operating Trustee shall direct any Advisors that it retains,
and Grantor shall direct any Advisors that it retains, with regard to the
divestiture of the Disposition Property, to take appropriate steps to ensure
that such Advisors do not act as a conduit for communications between the
Operating Trustee and Grantor that are otherwise prohibited under the terms of
this Agreement.

      11. Grantor Involvement in TWE Management. Except as provided in Section
12(a), Grantor and its affiliates shall not have an interest in, control of or
involvement in the operation or management of TWE, or seek to influence the
operation or management of TWE or any cable system in which TWE has an
interest, other than Kansas City Cable Partners and Texas Cable Partners, L.P.,
on account of AT&T Comcast's 50% general partnership interest therein which is
held outside of TWE; provided that Grantor and its affiliates shall not: (i)
receive information from Kansas City Cable Partners or Texas Cable Partners,
L.P. regarding the price, terms or conditions that TWE, or any affiliate of AOL
Time Warner that is a successor to TWE's interest in Kansas City Cable Partners
or Texas Cable Partners, L.P. or any of TWE's or such successor's affiliates
(other than Kansas City Cable Partners or Texas Cable Partners, L.P. or any of
their subsidiaries), negotiates for carriage of video programming on the cable
systems owned by Kansas City Cable Partners or Texas Cable Partners, L.P.; or
(ii) provide information to Kansas City Cable Partners or Texas Cable Partners,
L.P. regarding the price, terms or conditions that


                                     -22-


Grantor or its affiliates negotiate for the carriage of video programming on
the cable systems owned by Grantor or its affiliates. For purposes of this
Section 11, the term "TWE" shall include TWE and any other issuer of securities
or ownership interests constituting Disposition Property. This Section 11 will
cease to apply with respect to Kansas City Cable Partners or Texas Cable
Partners, L.P., as the case may be, at such time as neither TWE nor any other
affiliate of AOL Time Warner owns any interest in such entity.

      12.  Communications.

           (a)  Communications Regarding Operation and Management of TWE.

                 (i) The Operating Trustee shall not provide any information
           to Grantor concerning the operation or management of TWE or the
           operation or management of the cable systems in which TWE has a
           direct or indirect interest, except that the Operating Trustee
           shall use its reasonable best efforts to obtain and provide Grantor
           with financial statements and tax information with respect to TWE
           and the MOTH TWE Interest as and when furnished by TWE and as
           required by Grantor or its affiliates for compliance with
           securities and tax laws, rules and regulations, or other applicable
           legal or regulatory requirements. None of Grantor, or any of its
           affiliates, or any of its or their officers, directors or
           employees, shall communicate with the Operating Trustee, directly
           or indirectly, including indirectly through their Advisors,
           regarding the operation or management of TWE or the operation or
           management of any cable system in which TWE has an interest.

                 (ii) The Operating Trustee shall have such access to Grantor
           and its affiliates' personnel, books, records and facilities
           related to the Disposition


                                     -23-


           Property as may be reasonably necessary for the Operating Trustee
           to fulfill its obligations hereunder.

                 (iii) Any communications between the Operating Trusteee and
           Grantor or its affiliates permitted by this subsection (a) shall be
           in writing.

           (b) Communications Regarding Public Sale or Alternate Disposition.
The Operating Trustee and Grantor and its affiliates may engage in
communications in order to facilitate divestiture of the Disposition Property
through any Public Sale or Alternate Disposition. The Operating Trustee shall
provide periodic reports (no less frequently than quarterly during the 5-Year
Period and no less frequently than monthly thereafter) to Grantor (with a copy
to the Media Bureau) describing the Operating Trustee's efforts to accomplish
divestiture of the Disposition Property through any Public Sale or Alternate
Disposition, provided, however, that to the extent such reports contain
information that Grantor deems confidential, such reports shall be provided to
the Media Bureau only after such confidential information has been redacted. In
the event that such reports are provided to the Media Bureau in redacted form,
the unredacted versions of such reports will be maintained by the Operating
Trustee, or its designee, at a location in the Washington, D.C. area, and shall
be made available upon request for inspection by the Media Bureau during normal
business hours. Upon request by the Media Bureau, the Operating Trustee shall
file the unredacted version of any such report with the Media Bureau
accompanied by a request for confidential treatment. Grantor will use its
reasonable best efforts, consistent with the terms of this Agreement and
applicable FCC Regulations, to assist the Operating Trustee in accomplishing
the divestiture of the Disposition Property, including using its reasonable
best efforts to provide such information as is required by the Operating
Trustee to effect such divestiture.


                                     -24-


           (c) Communications Regarding Fiduciary Matters. Communications
between the Trustees and Grantor regarding the fiduciary obligations owed by
the Trustees to Grantor shall be permitted at any time.

           (d) The Operating Trustee shall retain copies of all written
communications between the Operating Trustee or its Advisors and Grantor, its
affiliates or its Advisors. The Operating Trustee shall prepare (or, as
appropriate, instruct its Advisors to prepare) and retain a contemporaneous
written summary of all oral communications between the Operating Trustee or its
Advisors and Grantor, its affiliates or its Advisors, pursuant to subsections
(b) and (c) of this Section 12, provided that such summary shall not be
required for oral communications that are ministerial or non-substantive in
nature, or are otherwise not material to the performance of the Operating
Trustee's fiduciary obligations to Grantor or its efforts to (a) divest the
Disposition Property or (b) effect an Alternate Disposition in accordance with
the terms of this Agreement. All written communications and summaries of oral
communications shall be maintained by the Operating Trustee, or its designee,
at a location in the Washington, D.C. area, and shall be made available upon
request for inspection by the Media Bureau during normal business hours.

           (e) Subject to a customary confidentiality agreement and to the
terms of any other agreement to which the Trust is a party or otherwise
subject, the Operating Trustee shall permit prospective purchasers of the
Disposition Property in an Alternate Disposition (at the request of the
Grantor) to have access to any and all financial or operational information to
which the Operating Trustee has access, as may be relevant to divestiture of
the Disposition Property.

           (f) All notices, requests, consents, approvals, waivers and demands

                (ii) expiration of the six-month period following the 5-Year
           Period, provided, however, that if any portion of the Disposition
           Property remains in the Trust at the expiration of the six-month
           period following the 5-Year Period, the Trust will continue until
           the FCC either approves the dissolution of the Trust or the
           remainder of the Disposition Property has been divested and all
           proceeds due to the order of Grantor with respect to such
           divestiture have been paid, in the manner provided in Sections 5(e)
           and 6(a); or

           (b) Upon dissolution of the Trust, the Operating Trustee shall take

or such other party designated by Grantor in writing to the Operating Trustee,
all property then held by the Trust or the Operating


                                     -27-


Trustee on behalf of the Trust pursuant to this Agreement, subject to
satisfaction (whether by payment or reasonable provision therefor) of claims of
all creditors of the Trust (other than Grantor) including, without limitation,
the Trustees. The Operating Trustee shall have a reasonable period to conclude
the administration of the Trust, and shall be compensated for all reasonably
necessary services performed after the dissolution date. Following completion
by the Operating Trustee of the actions required by this Section 13(b), the
Operating Trustee shall provide written notice to Grantor and, upon written
request of Grantor, the Trustees shall terminate the legal existence of the
Trust by canceling the Certificate of Trust in accordance with the Act.

           (c) Notwithstanding any other provision of this Section 13, upon a
Dissolution Event, Grantor may elect, in lieu of dissolving the Trust, to
terminate this Agreement and to convert the Trust into a Delaware limited
liability company, Delaware corporation or other legal entity, which conversion
shall be upon such terms as Grantor shall deem appropriate; provided that upon
completion of such conversion all rights, obligations, assets and liabilities
of the Trust remain, under applicable law, rights, obligations, assets and
liabilities of the entity so created. The Trustees shall cooperate with Grantor

           (d) At any time, subject to the Governing Agreements, Grantor may
cause the Trustees to merge the Trust with Trust I, or to transfer all of the
assets and liabilities of the Trust (including, without limitation, the
Disposition Property) to Trust I, or to accept a transfer of all of the assets
and liabilities of Trust I to the Trust; provided that, in each case and to the
extent required under the Governing Agreements, the successor or transferee
trust shall assume the obligations of the merged or transferor trust under the
Governing Agreements (other than the Declaration of Trust of the merged or
transferor trust). For purposes of this Section 13(d), the


                                     -28-


term "Governing Agreements" includes the "Governing Agreements" as defined in
this Agreement and in the Declaration of Trust of the successor or transferee,
or merged or transferor, trust, as the case may be.

effect such assignments of the MOTH TWE Assumed Rights and MOTH TWE Assumed
Obligations to Trust I and/or Trust II as the Grantor shall request in writing
and (ii) immediately following such assignment (or if there is no such
assignment, then at the closing of the TWE Restructuring) cause the Trust to
merge with and into Grantor, pursuant to such terms as the Grantor shall deem
appropriate, or to dissolve.

      14. Modification. This Agreement shall not be modified except by an
instrument in writing executed by Grantor and the Operating Trustee; provided
that the rights, duties, responsibilities and compensation of the Delaware
Trustee shall not be changed without the prior written consent of the Delaware
Trustee. No modifications of this Agreement, except for modifications that are
insubstantial and immaterial, shall be made unless approved by the Media
Bureau. A request for approval of a modification of this Agreement shall be
deemed approved unless the Media Bureau notifies the Operating Trustee, in
writing and within 14 days of receipt of such request from the Operating
Trustee, that it objects to such modification. A copy of any insubstantial and
immaterial modification in the Trust shall be filed with the FCC within ten
days following the execution thereof, with a copy to the Media Bureau. The
parties shall cooperate in the modification of this Agreement in the event
changes or modifications are needed in order to bring this Agreement and the
transactions contemplated hereby into compliance with applicable FCC
Regulations or other applicable laws.


                                     -29-


      15. Assignment. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their respective permitted successors and
permitted assigns. Subject to the power to delegate the performance of
ministerial responsibilities hereunder as deemed necessary by the Operating
Trustee, this Agreement shall not be assignable by the Trustees. Grantor shall
be entitled to assign its rights hereunder to AT&T Comcast or any subsidiary
thereof or any person who becomes the direct or indirect beneficial owner of
the Disposition Property as a result of a merger or transfer of all or
substantially all the assets of AT&T Comcast or any of its subsidiaries.

      16. Confidentiality. This Agreement and all matters concerning the
performance, enforcement and interpretation hereof shall be kept in strict
confidence by the parties, except where disclosure is required by law, rule or
regulation (including the Federal securities laws or FCC Regulations), to carry
out the express purposes and terms of this Agreement, or in connection with any
claims or actions relating to this Agreement.

      17.  Miscellaneous.

           (a) If any part of any provision of this Agreement or any other
agreement, document or writing given pursuant to or in connection with this
Agreement shall be invalid or unenforceable under applicable law, said part
shall be ineffective to the extent of such invalidity only, without in any way
affecting the remaining part of said provision or the remaining provisions of
this Agreement.
