Ladies and Gentlemen:

1.       The Exchange Offer. AT&T Corp., a New York corporation ("AT&T"), AT&T
         Broadband Corp., a Delaware corporation ("Broadband"), MediaOne Group,
         Inc., a Delaware corporation ("MediaOne"), AT&T Broadband, LLC, a
         Delaware limited liability company ("TCI"), AT&T Comcast Corporation, a
         Pennsylvania corporation ("AT&T Comcast"), and Comcast Cable
         Communications, Inc. ("Comcast Cable", together with MediaOne, TCI and
         AT&T Comcast, the "Guarantors" and, collectively with AT&T and
         Broadband, the "Registrants"), plan to commence an exchange offer for
         (i) AT&T's notes listed on Schedule I hereto under the heading
         "Broadband Eligible Notes" (collectively, the "Broadband Eligible
         Notes") for a like principal amount of Broadband Exchange Notes of AT&T
         and Broadband (the "Broadband Exchange Notes"), which will be
         mandatorily exchanged for notes (the "New Broadband Notes") of
         Broadband, and (ii) AT&T's notes listed on Schedule I hereto under the
         heading "AT&T Eligible Notes" (collectively, the "AT&T Eligible Notes",
         and together with the Broadband Eligible Notes, the "Securities") for a
         like principal amount of notes of AT&T (the "New AT&T Notes", together
         with the Broadband Exchange Notes

         and the New Broadband Notes, the "New Notes") and engage in a related
         solicitation of consents from holders of the Securities to certain
         amendments to the Indenture, dated as of September 7, 1990, between
         AT&T and The Bank of New York (the "Trustee"), as amended by a
         supplemental indenture, dated as of October 30, 1992, between AT&T and
         the Trustee, under which the Securities were issued (the "AT&T
         Indenture") (such exchange offer and consent solicitation hereinafter
         referred to, together with any amendments, supplements or extensions
         thereof, as the "Exchange Offer"), on the terms and subject to the
         conditions set forth in the Exchange Offer Material (as hereinafter
         defined) as the same may be amended or supplemented from time to time.
         The New Broadband Notes are to be guaranteed (the "Guarantees") on an
         unsecured and unsubordinated basis by the Guarantors.

2.       Appointment as Dealer Managers. The Registrants hereby appoint you and
         your affiliates as Dealer Managers and Solicitation Agents
         (collectively, the "Dealer Managers" or "you") and authorize you to act
         as such in connection with the Exchange Offer. On the basis of the
         representations, warranties and covenants of the Registrants and
         Comcast Corporation, a Pennsylvania corporation ("Comcast" and,
         together with the Registrants, the "Companies"), contained herein, you
         agree, in accordance with your customary practice, to perform those
         services in connection with the Exchange Offer as are customarily
         performed by investment banks in connection with exchange offers and
         consent solicitations of a like nature, including, but not limited to,
         communicating generally regarding the Exchange Offer with brokers,
         dealers, commercial banks and trust companies and other holders of the
         Securities. You further agree that you will not make any statements or
         disseminate any information about or concerning the Companies, their
         businesses or subsidiaries, or the Exchange Offer, other than as
         disclosed in the Exchange Offer Material. You have been engaged to act
         as the sole Dealer Managers in connection with the Exchange Offer and
         in such capacity, each of you shall act as an independent contractor,
         and each of your duties arising out of your engagement pursuant to this
         Agreement shall be owed solely to the Companies.

         The Registrants further authorize you to communicate with The Bank of
         New York in its capacity as exchange agent for the Exchange Offer with
         respect to all of the Securities other than the Luxembourg Notes (as
         defined in the Exchange Offer Material) (the "Exchange Agent"), The
         Bank of New York (Luxembourg) S.A., in its capacity as exchange agent
         and listing agent (the "Luxembourg Agent") for the Exchange Offer with
         respect to the Luxembourg Notes (as defined in the Prospectus) and D.F.
         King & Co. Inc. in its capacity as information agent for the Exchange
         Offer (the "Information Agent"), with respect to matters relating to
         the Exchange Offer. AT&T has instructed the Exchange Agent to advise
         you at least daily as to the number of Securities which have been
         tendered pursuant to the Exchange Offer and as to such other matters in
         connection with the Exchange Offer as you may reasonably request.


                                       2

3.       No Liability for Acts of Brokers, Dealers, Banks, Trust Registrants and
         Other Nominees. Neither you nor any of your affiliates, officers, other
         employees or directors shall have any liability to the Companies or any
         other person for any losses, claims, damages, liabilities and expenses
         (each, a "Loss" and collectively, the "Losses") arising from any act or
         omission on the part of any broker or dealer in securities (other than
         any of your affiliates), bank, trust company, any other nominees or any
         other person, and neither you nor any of your affiliates, officers,
         other employees or directors shall be liable for any Losses arising
         from your own acts or omissions in performing your obligations as
         Dealer Managers hereunder, except for any such Losses which are finally
         and judicially determined to have resulted primarily from your bad
         faith or gross negligence. In soliciting or obtaining tenders and
         consents, no dealer, bank, trust company or other nominee is to be
         deemed to be acting as your agent or the agent of the Companies or any
         of their affiliates, and you, as Dealer Managers, are not to be deemed
         the agent of any dealer, bank, trust company or other nominee or the
         agent or fiduciary of the Companies or any of their affiliates,
         security holders, creditors or of any other person. In soliciting or
         obtaining tenders and consents, you shall not be and shall not be
         deemed for any purpose to act as a partner or joint venturer of or a
         member of a syndicate or group with the Companies or any of their
         affiliates in connection with the Exchange Offer, any acceptance of the
         Securities or the consents, or otherwise, and neither the Companies nor
         any of their affiliates shall be deemed to act as your agent. AT&T and
         Comcast, acting jointly, shall have sole authority for the acceptance
         or rejection of any and all tenders. In addition, the obligations of
         the Dealer Managers under this Agreement are several and not joint, and
         no Dealer Manager shall be liable for any acts or omissions of any
         other Dealer Manager.

4.       The Exchange Offer Material and Withdrawal Rights. The Registrants
         agree to furnish you, at their expense, with as many copies as you may
         reasonably request of (i) each of the documents that is filed by the
         Registrants with the Securities and Exchange Commission (the
         "Commission") or any other U.S. federal, state, local or foreign
         governmental or regulatory authorities or agency (the "Other Agencies")
         or any court in connection with the Exchange Offer, including the
         registration statement on Form S-4 relating to the Exchange Offer (as
         it may be amended or supplemented and including the documents
         incorporated by reference therein and all financial statements,
         schedules and exhibits, as applicable, the "Registration Statement")
         and any preliminary prospectus or any final prospectus included
         therein, as filed with, or delivered for filing to the Commission
         pursuant to Rule 424 of the Securities Act of 1933, as amended, and the
         rules and regulations promulgated by the Commission thereunder
         (collectively, the "Securities Act") filed with the Commission in
         connection with the Exchange Offer and all documents incorporated
         therein by reference, (ii) the Letter(s) of Transmittal for the
         Exchange Offer and any related letters, filings, documents, releases or
         communications mailed, delivered, published or filed by or on behalf of
         the Registrants, in connection with the Exchange Offer, (iii) any other
         document required to be filed with the Commission pursuant to the
         provisions of the Securities Act and the Securities Exchange Act of
         1934, as amended, and the

                                       3

         rules and regulations promulgated by the Commission thereunder
         (collectively, the "Exchange Act") pertaining to either the Exchange
         Offer or the Registrants during the term of this Agreement and (iv)
         each appendix, attachment, modification, amendment or supplement to any
         of the foregoing and all related documents (each of (i), (ii), (iii)
         and (iv), together with each document incorporated by reference in any
         of the foregoing, the "Exchange Offer Material"). The final prospectus
         included in the Registration Statement (including any documents
         incorporated by reference therein and as it may be amended or
         supplemented from time to time) is herein called the "Prospectus,"
         except that if the final prospectus furnished to the Dealer Managers
         for use in connection with the Exchange Offer differs from the
         prospectus set forth in the Registration Statement (whether or not such
         prospectus is required to be filed pursuant to Rule 424 (b)), the term
         "Prospectus" shall refer to the final prospectus furnished to the
         Dealer Managers for such use and as it may be amended or supplemented.
         The Exchange Offer Material has been or will be prepared and approved
         by, and is the sole responsibility of, the Companies. At the
         commencement of the Exchange Offer, the Registrants shall cause timely
         to be mailed, to each registered holder of any Securities, the Exchange
         Offer Material and any other offering materials prepared expressly for
         use by holders of Securities tendering in the Exchange Offer, together
         with a return envelope. Thereafter, to the extent practicable, until
         the expiration of the Exchange Offer, the Registrants shall use their
         commercially reasonable efforts to cause copies of such materials and a
         return envelope to be mailed to each additional person who becomes a
         record holder of any applicable Securities.

         The Companies acknowledge and agree that each of you may use the
         Exchange Offer Material as specified herein without assuming any
         responsibility for independent investigation or verification on your
         part and the Companies represent and warrant to you that you may rely
         on the accuracy and adequacy of any information delivered to you by or
         on behalf of the Companies without assuming any responsibility for
         independent verification of such information or without performing or
         receiving any appraisal or evaluation of the Companies' assets or
         liabilities. You acknowledge and agree that you will not use any
         Exchange Offer Material after such time as any of the Companies has
         notified you that such Exchange Offer Material is inaccurate or
         otherwise inadequate, or use any Exchange Offer Material that has been
         amended or supplemented without such amendment or supplement.

         You hereby agree, as Dealer Managers, that, without the prior consent
         of the Registrants, you will not disseminate any written material for
         or in connection with the solicitation of tenders of the Securities
         pursuant to the Exchange Offer other than the Exchange Offer Material.

         The Registrants agree that no Exchange Offer Material will be used in
         connection with the Exchange Offer or filed with the Commission or any
         Other Agency with respect to the Exchange Offer without first providing
         you a copy thereof a reasonable time prior to such time as such
         materials are proposed to be used and

                                       4

         giving reasonable consideration to your and your counsel's comments, if
         any thereon. In the event that (a) any of the Companies use or permits
         the use of any Exchange Offer Material in connection with the Exchange
         Offer or files any such material with the Commission or any Other
         Agency and such materials unreasonably fail to address any comments
         provided by you or your counsel, (b) any of the Companies shall have
         breached any of its representations, warranties, agreements or
         covenants herein in any material respect or (c) any condition set forth
         in Section 10 hereof shall have failed to have been satisfied, then any
         of you shall be entitled to (I) withdraw as a Dealer Manager in
         connection with the Exchange Offer without any liability or penalty to
         you or any person indemnified under Section 11 hereof for such
         withdrawal, and without loss of any right to the indemnification
         provided in such Section 11, (II) the payment of all fees and expenses,
         if any, payable under this Agreement which have accrued pursuant to the
         applicable Fee Side Letters (as defined below) to the date of such
         withdrawal or would otherwise be due to any of you on such date and
         (III) the benefit of any other provisions surviving such withdrawal
         pursuant to Section 14 hereof. If any Dealer Manager withdraws as a
         Dealer Manager hereunder, the fees accrued and reimbursement for such
         Dealer Manager's expenses that are payable pursuant to the terms of the
         applicable Fee Side Letters through the date of such withdrawal shall
         be paid to the withdrawing Dealer Manager on or promptly after such
         date.

5.       Compensation. In consideration for each of your services as financial
         advisor to the Companies in connection with the Exchange Offer,
         including each of your services as Dealer Manager, AT&T agrees to pay
         Credit Suisse First Boston Corporation, Deutsche Bank Securities Inc.
         and Goldman, Sachs & Co. the fees specified in the side letter between
         such parties and Comcast agrees to pay J.P. Morgan Securities Inc.,
         Merrill Lynch, Pierce, Fenner and Smith Incorporated and Morgan Stanley
         & Co. Incorporated the fees specified in the letter between such
         parties dated October 3, 2002 (collectively, the "Fee Side Letters").
         Such payment shall be made pursuant to and in accordance with the terms
         of such Fee Side Letters, respectively.

6.       Expenses of Dealer Manager and Others. In addition to your compensation
         for your services hereunder pursuant to Section 5 hereof, expenses for
         which you are entitled to reimbursement under the Fee Side Letters
         shall be paid to you in accordance with the Fee Side Letters.

7.       Holder Lists. AT&T will cause you to be provided with cards or lists or
         other records showing the names and addresses (if available) of, and
         the principal amount of the Securities, held by, the holders of the
         Securities as of a recent date and will cause you to be advised from
         day to day during the period of the Exchange Offer as to any transfers
         of record of Securities. You agree that, except as may be required by
         law or the applicable rules and regulations of any self-regulatory
         organization, such cards or lists or other records shall be kept
         confidential and shall be used only in connection with your duties as
         Dealer Manager hereunder or as otherwise requested by the Companies.


                                       5

8.       Additional Obligations of the Registrants.

         a)       Unless the Registrants terminate the Exchange Offer, the
                  Companies will prepare and file, as required by applicable
                  law, any and all necessary amendments or supplements to any of
                  the Exchange Offer Material, will promptly furnish to you true
                  and complete copies of each such amendment and supplement
                  within a reasonable period of time prior to the filing thereof
                  and will notify you as promptly as practicable of the same
                  becoming effective. The Registrants will not file any
                  amendment or supplement to the Registration Statement or the
                  Prospectus without first providing you a copy thereof a
                  reasonable time prior to such time as such materials are
                  proposed to be used and giving reasonable consideration to
                  your and your counsel's comments, if any thereon.

         b)       The Registrants will advise each of you as promptly as
                  practicable (confirming such advice in writing) of (i) the
                  time when the Registration Statement has become effective and
                  when any post-effective amendment thereto becomes effective,
                  (ii) the occurrence of any event, or the discovery of any
                  fact, the occurrence or existence of which it believes would
                  require the making of any change in any of the Exchange Offer
                  Material then being used or would cause any representation or
                  warranty contained in this Agreement to be untrue or
                  inaccurate in any material respect, (iii) any proposal or
                  requirement to make, amend or supplement any filing required
                  by the Securities Act, the Exchange Act, "blue sky" or other
                  U.S. and non-U.S. state securities laws or any Other Agency in
                  connection with the Exchange Offer or to make any filing in
                  connection with the Exchange Offer pursuant to any other
                  applicable law, rule or regulation, (iv) the issuance by the
                  Commission or any Other Agency of any comment or order or the
                  taking of any other action concerning the Registration
                  Statement, the Prospectus or the Exchange Offer (and, if in
                  writing, will furnish you with a copy thereof), (v) any
                  material developments in connection with the Exchange Offer,
                  including, without limitation, the commencement of any lawsuit
                  concerning the Exchange Offer, and (vi) any other information
                  relating to the Exchange Offer, the Exchange Offer Material or
                  this Agreement which you may from time to time reasonably
                  request. If at any time the Commission shall issue any order
                  suspending the effectiveness of the Registration Statement,
                  any U.S. and non-U.S. state securities commission or other
                  regulatory authority shall issue an order suspending the
                  qualification of the Securities or the New Notes under U.S.
                  and non-U.S. state securities or "blue sky" laws or any Other
                  Agency shall issue any order impeding the making or
                  consummation of the Exchange Offer, the Registrants shall
                  notify you of such order as promptly as practicable and shall
                  make reasonable effort to obtain the lifting or removal
                  thereof as soon as possible.

         c)       Prior to the issuance of the New Notes, the Registrants shall
                  (i) obtain the registration or qualification thereof under the
                  U.S. and non-U.S. securities or "blue sky" laws of such
                  jurisdictions as may be required for the

                                       6

                  consummation of the Exchange Offer and (ii) comply with any
                  requirements of the NASD, LSE and NYSE and any Other Agency
                  (together the "Exchanges") with respect to the Exchange Offer,
                  including with respect to the listing of the New Notes,
                  Broadband Exchange Notes and New Broadband Notes on the NYSE
                  and certain New Notes on the LSE, and shall furnish you with
                  preliminary and final forms of "blue sky" memoranda, if
                  applicable, evidencing such registration and qualification.

         d)       Until the Exchange Offer is completed or terminated, AT&T,
                  Comcast and Comcast Cable will deliver to you, promptly upon
                  their becoming available, copies of all financial statements,
                  reports, notices and proxy statements sent by AT&T, Comcast
                  and Comcast Cable to their security holders, and of all
                  current, regular and periodic reports filed by AT&T, Comcast
                  and Comcast Cable or any of their subsidiaries with any
                  securities exchange or with the Commission or any governmental
                  authority succeeding to any of the Commission's functions.

         e)       In making and consummating the Exchange Offer, AT&T will fully
                  comply in a timely manner in all material respects with the
                  applicable requirements of the Securities Act, the Exchange
                  Act and the Trust Indenture Act of 1939, as amended, and the
                  rules and regulations promulgated by the Commission thereunder
                  (the "Trust Indenture Act") and any applicable non-U.S. laws
                  and requirements.

         f)       AT&T, AT&T Comcast and Comcast Cable agree to make generally
                  available to their security holders as soon as practicable an
                  earnings statement that will satisfy the provisions of Section
                  11(a) of the Securities Act covering a twelve month period
                  beginning not later than the first day of AT&T's, AT&T
                  Comcast's and Comcast Cable's fiscal quarter next following
                  the effective date of the Registration Statement.

9.       Additional Representations, Warranties and Covenants of the
         Registrants.

         would not materially adversely affect the ability of the Comcast
         Parties to execute, deliver and perform this Agreement or to commence
         and consummate the Comcast Transactions in accordance with their terms.

                  (vi) The Comcast Transactions do not and will not (i) conflict
         with or result in a violation of any of the provisions of the
         certificate of incorporation or by-laws of any of the Comcast Parties,
         (ii) conflict with, or result in the acceleration of any obligation
         under or in a breach of, or constitute a default under, any of the
         provisions of any indenture, agreement or undertaking to which any of
         the Comcast Parties or any of their subsidiaries is a party or by which
         any of them is bound or to which any of their property or assets is
         subject or (iii) contravene any federal, state or local law, rule or
         regulation applicable to any of the Comcast Parties or any of their
         subsidiaries, or any order applicable to any of them of any court or
         any other governmental agency or instrumentality having jurisdiction
         over it or any of their property.

              (vii) No stop order suspending the effectiveness of the
         Registration Statement has been issued and no proceedings for that
         purpose are pending or, to the knowledge of the Comcast Parties,
         threatened by the Commission and no injunction suspending the offer,
         issuance, delivery or exchange of the New Notes pursuant to the
         Exchange Offer has been issued and no proceedings for that purpose are
         pending or, to the knowledge of the Comcast Parties, have been
         threatened

                                       14

              (viii) Since the respective dates as of which information is given
         in the Exchange Offer Material (other than AT&T Material), there has
         not been any material adverse change, financial or otherwise, in the
         condition of the Comcast Parties from that set forth in the Exchange
         Offer Material (other than with respect to AT&T Material) or in
         Comcast's reports filed with the Commission pursuant to Section 13(a)
         of the Exchange Act.

              (ix) Deloitte & Touche LLP, the accountants who have certified the
         financial statements and supporting schedules of the Comcast Parties
         included or incorporated by reference in the Exchange Offer Material,
         are independent public accountants with respect to the Comcast Parties
         and their subsidiaries as required by the Securities Act.


              (x) The financial statements, together with the related schedules
         and notes of the Comcast Parties, included or incorporated by reference
         in the Exchange Offer Material, present fairly in all material respects
         the combined financial position, results of operations and changes in
         financial position of the Comcast Parties and their subsidiaries on the
         basis stated in the Exchange Offer Material or incorporated therein by
         reference as of the respective dates indicated and for the respective
         periods specified; except as otherwise stated therein, said financial
         statements and related schedules and notes have been prepared in
         conformity with generally accepted accounting principles applied on a
         consistent basis; and the other financial and statistical information
         and data of the Comcast Parties included or incorporated by reference
         in the Exchange Offer Material is, in all material respects, fairly
         presented and prepared on a basis consistent with such financial
         statements and derived from books and records of the Comcast Parties,
         as applicable.


              (xi) The Guarantees have been duly authorized and, when the New
         Broadband Notes have been duly executed, authenticated and delivered in
         accordance with the terms of the New Broadband Indenture, will be the
         legal, valid and binding obligations of the Comcast Parties (other than
         Comcast) entitled to the benefits of the New Broadband Indenture and
         enforceable against them in accordance with their terms except as
         enforceability thereof may be limited by bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and other similar laws
         now or hereafter in effect relating to creditors' rights generally and
         general principles of equity.

              (xii) The New Broadband Indenture has been duly authorized and,
         when executed and delivered by the Comcast Parties (other than
         Comcast), will be a legal, valid and binding agreement of Comcast
         Parties (other than Comcast) enforceable against them in accordance
         with its terms except as enforceability thereof may be limited by
         bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
         and other similar laws now or hereafter in effect relating to
         creditors' rights generally and general principles of equity. The form
         of the New Broadband Indenture conforms in all material respects to the


                                       15

         requirements of, and when filed in definitive form with the Commission
         will be qualified under, the Trust Indenture Act.

              (xiii) The statements in the Prospectus under "Description of the
         New Broadband Notes and the Cable Guarantees" and "Comparison of the
         New Broadband Notes and the Broadband Exchange Notes", insofar as such
         statements constitute a summary of the legal matters or documents
         referred to therein, fairly present the information called for with
         respect to such legal matters and documents.

20.      Counterparts; Severability. This Agreement may be executed in two or
         more separate counterparts, each of which shall be deemed an original,
         but all of which together shall constitute one and the same instrument.
         Any term or provision of this Agreement which is invalid or
         unenforceable in any jurisdiction, by any rule of law, or public
         policy, shall, as to such jurisdiction, be ineffective to the extent of

         unenforceable the remaining terms and provisions of this Agreement or
         affecting the validity or enforceability of any of the terms or
         provisions of this Agreement in any other jurisdiction. Upon such
         determination that any term or provision is invalid, illegal or

         in this Agreement, express or implied, is intended to or shall confer
         upon any other person any right, benefit or remedy of any nature
         whatsoever under or by reason of this Agreement.

22.      Tombstone. The Companies acknowledge that each of the Dealer Managers
         may at its own expense place an announcement in such newspapers and
         periodicals as it may choose (in addition to the announcement specified
         in Section 6(c)), stating that such Dealer Manager has acted or is
         acting as Dealer Manager and financial advisor to the Companies in
         connection with the Exchange Offer.

23.      Trading Activities. Each of the Companies acknowledges that, at any

         account or for the accounts of their customers, and accordingly may
         hold a long or short position in the Securities, the New Notes or other
