          year and the denominator of which is 365. Such award shall be paid to
          the Executive as soon as practicable after the 2005 Annual Meeting.

has accordingly been assumed by AT&T and the Executive further acknowledges that
the Company shall have no obligation or liability to the Executive  with respect
to payment of such supplemental retirement benefit.

         SECTION 8.  Employee Benefit Programs.

         During the Term of  Employment,  the  Executive  shall be  entitled  to

programs  that may be sponsored by the Company from time to time,  including any
plans that  supplement  the  above-listed  types of plans or  programs,  whether

calculation  of all  benefits  shall  be  based  on,  the  assumptions  that the
Executive  has  met  all   service-period   or  other   requirements   for  such
participation  provided  that  no  such  assumptions  shall  be  made  as  to  a
tax-qualified plan if such assumption would jeopardize the tax- qualified status
of such plan.

          all outstanding RSUs (as well as the $10,000,000 guarantee set forth
          in Exhibit B), performance shares and other equity-based awards shall
          vest



                                       10



          and be paid out (at target, with respect to the performance shares) in
          a single installment promptly after his termination.

                  In no event shall a termination of the Executive's  employment
         for Disability  occur until the Party  terminating his employment gives
         written notice to the other Party in accordance with Section 24 below.




         (c) Termination by the Company for Cause.

                (i) A termination for Cause shall not take effect unless the
          provisions of this paragraph (i) are complied with. The Executive
          shall be given written notice by the Board, authorized by a vote of no
          less than 75% of the entire Board, of the intention to terminate him
          for Cause, such notice (A) to state in detail the particular act or
          acts or failure or failures to act that constitute the grounds on
          which the proposed termination for Cause is based and (B) to be given
          within six months of the Board learning of such act or acts or failure
          or failures to act. The Executive shall have ten calendar days after
          the date that such written notice has been given to the Executive in
          which to cure such conduct, to the extent such cure is possible. If he
          fails to cure such conduct, the Executive shall then be entitled to a
          hearing before the Board. Such hearing shall be held within 15
          calendar days of such notice to the Executive, provided he requests
          such hearing within ten calendar days of the written notice from the
          Board of the intention to terminate him for Cause. If, within five
          calendar days following such hearing, the Executive is furnished
          written notice by the Board confirming that, in its judgment, grounds
          for Cause on the basis of the original notice exist, he shall
          thereupon be terminated for Cause.

                (ii) In the event the Company terminates the Executive's
          employment for Cause:

                       (A) the  Executive  shall  be  entitled  to  Base  Salary
                  through the date of the termination;

                       (B) all  outstanding  options  which are not  exercisable
                  shall  be   forfeited;   exercisable   options   shall  remain
                  exercisable  until the earlier of the  ninetieth day after the
                  date of  termination or the  originally  scheduled  expiration
                  date of the options unless the Board determines otherwise;

                       (C) all restricted  stock as to which  restrictions  have
                  not lapsed shall be forfeited;

                       (D) all unvested RSUS shall be forfeited; and




                                       11


                       (E) all long-term  incentive  plan awards with respect to
                  performance  cycles which have not yet been completed shall be
                  forfeited.

         (d)  Termination  without Cause or  Constructive  Termination  without
Cause.  In the event the  Executive's  employment  is  terminated by the Company
without Cause, other than due to Disability or death, or in the event there is a
Constructive  Termination  without Cause, the Executive shall be entitled to the
following benefits:

               (i) Base Salary through the date of termination;

               (ii) an annual incentive award for the year in which termination
          occurs, equal to the Target Bonus for such year multiplied by a
          fraction, the numerator of which is the number of days that the
          Executive was employed during the applicable year and the denominator
          of which is 365, payable in a single installment promptly after his
          termination;

                (iii) all outstanding options, whether or not then exercisable,
          shall become exercisable and shall remain exercisable until the end of
          their originally scheduled ten-year terms;

                (iv) (A) any restrictions on any restricted stock shall lapse
          and (B) all outstanding RSUs (as well as the $10,000,000 guarantee set
          forth in Exhibit B), performance shares and other equity-based awards
          shall vest and be paid out (at target, with respect to the performance
          shares) in a single installment promptly after his termination; and

                (v) if such termination occurs on or prior to the second
          anniversary of the Effective Date, the Executive shall be entitled to
          receive a lump sum cash amount equal to the greater of (A) (X) the
          product of three multiplied by the sum of (I) the Base Salary, (II)
          the annual incentive award, equal to the target bonus established by
          AT&T for 2002, which was 150% of his then base salary, and (III) the
          long-term performance share award, equal to the performance share
          target set by AT&T for 2002 and (B) the product of four multiplied by
          the sum of Base Salary, at the annualized rate in effect on the date
          of termination, and the Target Bonus for the year in which the
          termination occurs (with respect to the Target Bonus, $2.7 million if
          such termination occurs in 2002 or 2005). If such termination occurs
          after the second anniversary of the Effective Date, the Executive
          shall be entitled to receive the payment set forth in clause (B) of
          this Section 10(d)(v).



                                       12



         (e) Voluntary Termination; Retirement.

                (i) Except as otherwise provided herein, termination of
          employment by the Executive on his own initiative, other than a
          termination due to death or Disability or a Constructive Termination
          without Cause or retirement following the end of the Term of
          Employment, shall have the same consequences as provided in Section
          10(c)(ii) for a termination for Cause. A voluntary termination under
          this Section 10(e) shall be effective 30 calendar days after prior
          written notice is received by the Company.

                (ii) Notwithstanding the foregoing, if the Executive elects to
          both (A) become Non-Executive Chairman of the Board prior to or at the
          2003 Annual Meeting and (B) retire from his position as Non-Executive
          Chairman of the Board prior to or at the 2004 Annual Meeting, but not
          earlier than January 1, 2004, the Company shall offer to enter into a
          consulting agreement with the Executive in the form attached hereto as
          Exhibit C under which he would serve as a consultant and senior
          advisor to the Company until the one year anniversary of the 2005
          Annual Meeting. All benefits owing to the Executive as a result of a
          retirement event described in the immediately preceding sentence shall
          be as set forth in the consulting agreement. The Company's failure to
          offer to enter into such consulting agreement shall constitute a
          termination of the Executive's employment without Cause covered by
          Section 10(d).

                (iii) The Executive may retire at any time following the end of
          the Term of Employment and thereupon commence receiving any benefits
          to which he is entitled as a retired senior executive in accordance
          with the Company's then existing plans and practices. Upon such
          retirement, all stock options, other than the Option, shall continue
          to be exercisable for the remainder of their originally scheduled
          ten-year terms.

          (f)   Gross-up Payment.

                (i) If the aggregate of all payments or benefits made or
          provided to the Executive under this Agreement and under all other
          plans and programs of the Company (the "Aggregate Payment") is
          determined to constitute a Parachute Payment within the meaning of
          Section 280G(b)(2) of the Code, the Company shall pay to the
          Executive, prior to the time any excise tax imposed by Section 4999 of
          the Code ("Excise Tax") is payable with respect to such Aggregate
          Payment, an additional amount (the "Gross-Up Payment") which, after
          the imposition of all income, employment, excise and other taxes
          thereon, is equal to the Excise Tax on the Aggregate Payment. The
          determination of whether the Aggregate



                                       13



          Payment constitutes a Parachute Payment and, if so, the amount to be
          paid to the Executive and the time of payment pursuant to this Section
          10(f)(i) shall be made by an independent auditor (the "Auditor")
          selected by the Parties and paid by the Company. The Auditor shall be
          a nationally recognized United States public accounting firm which has
          not, during the two years preceding the date of its selection, acted
          in any way on behalf of the Company or any Affiliate thereof. If the
          Executive and the Company cannot agree on the firm to serve as the
          Auditor, then the Executive and the Company shall each designate one
          accounting firm and those two firms shall jointly select the
          accounting firm to serve as the Auditor. All fees and expenses of the
          Auditor shall be borne solely by the Company. Any Gross- Up Payment
          shall be paid by the Company to the Executive within five calendar
          days of the receipt of the Auditor's determination. Any determination
          by the Auditor shall be binding upon the Company and the Executive.

                (ii) As a result of uncertainty in the application of Sections
          280G and 4999 of the Code at the time of the initial determination by
          the Auditor hereunder, it is possible that the Gross-Up Payment made
          will have been an amount more than the Company should have paid
          pursuant to Section 10(f)(i) (the "Overpayment") or that the Gross-Up
          Payment made will have been an amount less than the Company should
          have paid pursuant to Section 10(f)(i) (the "Underpayment"). In the
          event that there is a final determination by the Internal Revenue
          Service, or a final determination by a court of competent
          jurisdiction, that an Overpayment has been made, any such Overpayment
          shall be treated for all purposes as a loan to the Executive which the
          Executive shall repay to the Company together with interest at the
          applicable Federal rate provided for in Section 7872(f)(2) of the
          Code. In the event that there is a final determination by the Internal
          Revenue Service, a final determination by a court of competent
          jurisdiction or a change in the provisions of the Code or regulations
          pursuant to which an Underpayment arises under this Agreement, any
          such Underpayment shall be promptly paid by the Company to or for the
          benefit of the Executive together with interest at the applicable
          Federal rate provided for in Section 7872(f)(2) of the Code.

                (iii) The Executive shall notify the Company in writing of any
          claim by the Internal Revenue Service that, if successful, would
          result in an Underpayment and would require the payment by the Company
          of an additional Gross-Up Payment. Such notification shall be given as
          soon as practicable but no later than 10 business days after the
          Executive is informed in writing of such claim and shall apprise the
          Company of the nature of such claim and the date on which such claim
          is requested to be paid. The Executive shall not pay such claim prior
          to the expiration of the




                                       14



          30 calendar day period following the date on which the Executive gives
          such notice to the Company (or such shorter period ending on the date
          that any payment of taxes with respect to such claim is due). If the
          Company notifies the Executive in writing prior to the expiration of
          such period that it desires to contest such claim, the Executive
          shall:

                       (A) give the Company any information reasonably requested
                  by the Company relating to such claim,

                       (B) take such action in connection  with  contesting such
                  claim as the Company shall reasonably  request in writing from
                  time to time, including,  without limitation,  accepting legal
                  representation  with  respect  to such  claim  by an  attorney
                  reasonably selected by the Company,

                       (C)  cooperate  with the  Company  in good faith in order
                  effectively to contest such claim, and

                       (D) permit the Company to  participate  in any proceeding
                  relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income or employment tax (including
interest and penalties with respect thereto) imposed as a result of such
proceeding and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 10(f), the Company shall control all
proceedings taken in connection with such contest, provided that the Company's
control of the contest shall be limited to issues with respect to which a
Gross-Up Payment would be payable hereunder and Executive shall be entitled to
settle or contest, as the case may be, any other issue raised by the Internal
Revenue Service or any other taxing authority.

         (g) Other  Termination  Benefits.  In the case of any of the foregoing
         terminations  (other than retirement as  Non-Executive  Chairman of the
         Board pursuant to Section  10(e)(ii)) the Executive or his estate shall
         also be entitled to:

                (i) the balance of any incentive awards due for performance
          periods which have been completed, but which have not yet been paid;

                (ii) any expense reimbursements due the Executive;



                                       15



                (iii) other benefits, if any, in accordance with applicable
          plans and programs of the Company; and

                (iv) with respect to the Executive only, if such termination
          occurs on or prior to the second anniversary of the Effective Date,
          financial counseling services for a period of two years following the
          Executive's termination.

         (h) No  Mitigation;  No  Offset.  In the event of any  termination  of
employment  under this Section 10, the Executive shall be under no obligation to
seek other employment and there shall be no offset against amounts due the
Executive  under this Agreement on account of any  remuneration  attributable to
any subsequent employment that he may obtain.

                (i) Nature of Payments. Any amounts due under this Section 10
          are in the nature of severance payments considered to be reasonable by
          the Company and are not in the nature of a penalty.

         SECTION 11.  Confidential Information; Prohibited Public Statements;
Publicity.

         (a) The  Company (as  hereinafter  specially  defined for  purposes of
Sections  11  through  13  hereof),   pursuant  to  the  Executive's  employment
hereunder,  provides  him access to and  confides  in him  business  methods and
systems,  techniques and methods of operation  developed at great expense by the
Company ("Trade Secrets") and which the Executive recognizes to be unique assets
of the Company's business.  The Executive shall not, during or at any time after
the Term of  Employment,  directly  or  indirectly,  in any  manner  utilize  or
disclose to any person, firm,  corporation,  association or other entity, except
(i) where  required by law, (ii) to directors,  consultants  or employees of the
Company in the ordinary  course of his duties or (iii) during his employment and
in the ordinary course of his services as Chairman of the Board for such use and
disclosure  as he shall  reasonably  determine to be in the best interest of the
Company:  (A) any such Trade Secrets,  (B) any sales prospects,  customer lists,
products,  research  or data of any kind,  or (C) any  information  relating  to
strategic plans, sales, costs, profits or the financial condition of the Company
or any of its customers or prospective customers,  which are not generally known
to the public or  recognized  as standard  practice in the industry in which the
Company  shall be engaged.  The Executive  further  covenants and agrees that he
will promptly deliver to the Company all tangible  evidence of the knowledge and
information described in (A), (B) and (C), above, prior to or at the termination
of the Executive's employment. For purposes of Sections 11, 12 and 13 hereof the
term "Company" shall mean AT&T Comcast  Corporation  ("AT&T Comcast") as well as
(I) each of its more than fifty percent (50%) owned  subsidiaries  and (II) each
other entity in




                                       16



which AT&T Comcast directly or indirectly has a greater than ten percent (10%)
equity interest, the fair market value of which interest is in excess of
$50,000,000. In determining AT&T Comcast's equity interest for purposes of this
definition, any equity interest which AT&T Comcast has an option to purchase
shall be considered as owned by AT&T Comcast.

         (b) Neither the Executive nor the Company, its officers or directors
(collectively, the "Company Affiliated Entities") shall, either during or at any
time after the Term of Employment, directly or indirectly make any public
statement (including a private statement reasonably likely to be repeated
publicly) reflecting adversely on the Company Affiliated Entities or the
Executive, as the case may be, or the business prospects of the Company except
for (i) such statements which the Executive may be required to make in the
ordinary course of his service as a member of, including Chairman of, the Board
or (ii) with respect to each of the Executive and the Company Affiliated
Entities, as otherwise required by applicable law.

         (c) Neither the Executive nor the Company Affiliated Entities shall
publicly comment (including private statements reasonably likely to be repeated
publicly) on, or discuss the circumstances surrounding, this Agreement or the
consulting agreement attached hereto as Exhibit C, except as mutually agreed or
as required by applicable law.

         SECTION 12.  Noncompetition, Noninterference and Nonsolicitation.

         (a) Subject to the geographic limitation of Section 12(b) hereof, the
Executive during the Term of Employment and for a period of two (2) years
following termination of employment in accordance with this Agreement shall not,
directly or indirectly, on his behalf or on behalf of any other person, firm,
corporation, association or other entity, as an employee or otherwise, engage
in, or in any way be concerned with or negotiate for, or acquire or maintain any
ownership interest in any business or activity which is the same as or
competitive with that conducted by the Company at the termination of his
employment, or which was engaged in or developed by the Company at any time
during the Term of Employment for specific implementation in the immediate
future by the Company.

         (b) The Executive acknowledges that the Company is engaged in business
throughout the United States and in various foreign countries and that the
Company intends to expand the geographic scope of its activities. Accordingly
and in view of the nature of his position and responsibilities, the Executive
agrees that the provisions of this Section shall be applicable to each state and
each foreign country, possession or territory in which the Company may be
engaged in business during the Term of Employment, or, with respect to the
Executive's



                                       17



obligations following termination of his employment, at the termination of his
employment or at any time within the twelve-month period following the effective
date of his termination of employment.

         (c) The Executive agrees that for a period of two (2) years following
termination of employment in accordance with this Agreement, the Executive will
not, directly or indirectly, for himself or on behalf of any third party at any
time in any manner, request or cause any of the Company's customers to cancel or
terminate any existing or continuing business relationship with the Company;
solicit, entice, persuade, induce, request or otherwise cause any employee,
officer or agent of the Company (other than clerical employees of the Company)
to refrain from rendering services to the Company or to terminate his or her
relationship, contractual or otherwise, with the Company; induce or attempt to
influence any supplier to cease or refrain from doing business or to decline to
do business with the Company; divert or attempt to divert any supplier from the
Company; or induce or attempt to influence any supplier to decline to do
business with any businesses of the Company as such businesses are constituted
immediately prior to the termination of employment.

         (d) The Executive agrees that for a period of two (2) years following
his termination of employment in accordance with this Agreement, the Executive
will not directly or indirectly, for himself or on behalf of any third party,
solicit for business in competition with the business of the Company, accept any
business in competition with the business of the Company from or otherwise do,
or contract to do, business in competition with the business of the Company with
any person or entity who, at the time of, or any time during the twelve (12)
months preceding such termination, was an active customer or was actively
solicited by the Company according to the books and records of the Company and
within the knowledge, actual or constructive of the Executive.

         (e) Notwithstanding anything to the contrary in this Section 12, the
prohibitions and agreements contained in subsections 12(a), 12(c), and 12(d)
shall terminate immediately upon any termination of Executive's employment
hereunder following a Change in Control.

         (f) Nothing in this Section 12 shall prohibit the Executive from being
a passive owner of not more than one percent of the outstanding common stock,
capital stock and equity of any firm, corporation, or enterprise so long as the
Executive has no active participation in the management of the business of such
firm, corporation or enterprise.





                                       18



         SECTION 13.  Equitable Remedies.

         The Executive acknowledges that his compliance with the covenants in
Sections 11 and 12 of this Agreement is necessary to protect the good will and
other proprietary interests of the Company and that, in the event of any
violation by the Executive of the provisions of Section 11 or 12 of this
Agreement, the Company will sustain serious, irreparable and substantial harm to
its business, the extent of which will be difficult to determine and impossible
to remedy by an action at law for money damages. Accordingly, the Executive
agrees that, in the event of such violation or threatened violation by the
Executive, the Company shall be entitled to any injunction before trial from any
court of competent jurisdiction as a matter of course and upon the posting of
not more than a nominal bond in addition to all such other legal and equitable
remedies as may be available to the Company. The Executive further agrees that,
in the event any of the provisions of Sections 11 and 12 of this Agreement are
determined by a court of competent jurisdiction to be contrary to any applicable
statute, law or rule, or for any reason to be unenforceable as written, such
court may modify any of such provisions so as to permit enforcement thereof as
thus modified.

         SECTION 14.  Resolution of Disputes.

         Except as provided in Section 13, any disputes arising under or in
connection with this Agreement shall be resolved by third party mediation of the
dispute and, failing that, by binding arbitration, to be held in a location
mutually agreed to by the Parties, in accordance with the rules and procedures
of the American Arbitration Association. Judgment upon the award rendered by the
arbitrator(s) may be entered in any court having jurisdiction thereof. Each
Party shall bear his or its own costs of the mediation, arbitration or
litigation, except that the Company shall bear all such costs if the Executive
prevails in such mediation, arbitration or litigation on any material issue.

         SECTION 15.  Indemnification.

         (a) The Company agrees that if the Executive is made a party, or is
threatened to be made a party, to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding"), by reason of the
fact that he is or was a director, officer or employee of the Company or is or
was serving at the request of the Company as a director, officer, member,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, including service with respect to employee benefit plans,
whether or not the basis of such Proceeding is the Executive's alleged action in
an official capacity while serving as a director, officer, member, employee or
agent, the Executive shall be indemnified and held harmless by the Company to
the fullest extent legally permitted or authorized by the Company's certificate
of incorporation or bylaws



                                       19



or resolutions of the Company's Board of Directors or, if greater, by the laws
of the Commonwealth of Pennsylvania, against all cost, expense, liability and
loss (including, without limitation, attorney's fees, judgments, fines, ERISA
excise taxes or other liabilities or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by the Executive in connection
therewith, and such indemnification shall continue as to the Executive even if
he has ceased to be a director, member, employee or agent of the Company or
other entity and shall inure to the benefit of the Executive's heirs, executors
and administrators. The Company shall advance to the Executive all reasonable
costs and expenses incurred by him in connection with a Proceeding within 20
calendar days after receipt by the Company of a written request for such
advance. Such request shall include an undertaking by the Executive to repay the
amount of such advance if it shall ultimately be determined that he is not
entitled to be indemnified against such costs and expenses.

         (b) Neither the failure of the Company (including its board of
directors, independent legal counsel or shareholders) to have made a
determination prior to the commencement of any Proceeding concerning payment of
amounts claimed by the Executive under Section 15(a) above that indemnification
of the Executive is proper because he has met the applicable standard of
conduct, nor a determination by the Company (including its board of directors,
independent legal counsel or shareholders) that the Executive has not met such
applicable standard of conduct, shall create a presumption that the Executive
has not met the applicable standard of conduct.

         (c) The Company agrees to continue and maintain a directors' and
officers' liability insurance policy covering the Executive which is no less
favorable than the policy covering other senior officers of the Company.

         SECTION 16.  Assignability; Binding Nature.

         This Agreement shall be binding upon and inure to the benefit of the
Parties and their respective successors, heirs (in the case of the Executive)
and assigns. Rights or obligations of the Company under this Agreement may be
assigned or transferred by the Company pursuant to a merger or consolidation in
which the Company is not the continuing entity, or the sale or liquidation of
all or substantially all of the assets of the Company, provided that the
assignee or transferee is the successor to all or substantially all of the
assets of the Company and such assignee or transferee assumes the liabilities,
obligations and duties of the Company, as contained in this Agreement, either
contractually or as a matter of law. The Company further agrees that, in the
event of a sale of assets or liquidation as described in the preceding sentence,
it shall take whatever action it reasonably can in order to cause such assignee
or transferee to expressly assume the liabilities, obligations and duties of the
Company hereunder. No rights or




                                       20



obligations of the Executive under this Agreement may be assigned or transferred
by the Executive other than his rights to compensation and benefits, which may
be transferred only by will or operation of law.

         SECTION 17.  Representation.

         The Company represents and warrants that it is fully authorized and
empowered to enter into this Agreement and that the performance of its
obligations under this Agreement will not violate any agreement between it and
any other person, firm or organization. The Executive represents that the
performance of his obligations under this Agreement will not violate any
agreement between him and any other person, firm or organization that would be
violated by the performance of his obligations under this Agreement.

         SECTION 18.  Entire Agreement.

         This Agreement contains the entire understanding and agreement between
the Parties concerning the subject matter hereof and supersedes all prior
agreements, understandings, discussions, negotiations and undertakings, whether
written or oral, between the Parties with respect thereto.

         SECTION 19.  Amendment or Waiver.

         No provision in this Agreement may be amended unless such amendment is
agreed to in writing and signed by the Executive and an authorized officer of
the Company. No waiver by either Party of any breach by the other Party of any
condition or provision contained in this Agreement to be performed by such other
Party shall be deemed a waiver of a similar or dissimilar condition or provision
at the same or any prior or subsequent time. Any waiver must be in writing and
signed by the Executive or an authorized officer of the Company, as the case may
be.

         SECTION 20.  Severability.

         In the event that any provision or portion of this Agreement shall be
determined to be invalid or unenforceable for any reason, in whole or in part,
the remaining provisions of this Agreement shall be unaffected thereby and shall
remain in full force and effect to the fullest extent permitted by law so as to
achieve the purposes of this Agreement.

         SECTION 21.  Survivorship.

         Except as otherwise expressly set forth in this Agreement, the
respective rights and obligations of the Parties hereunder, including the
covenants and the




                                       21



agreements of Executive set forth in Sections 11, 12 and 13, shall survive any
termination of the Executive's employment. This Agreement itself (as
distinguished from the Executive's employment) may not be terminated by either
Party without the written consent of the other Party.

         SECTION 22.  References.

         In the event of the Executive's death or a judicial determination of
his incompetence, reference in this Agreement to the Executive shall be deemed,
where appropriate, to refer to his beneficiary, estate or other legal
representative.

         This Agreement shall be governed in accordance with the laws of the
State of New York without reference to principles of conflict of laws.

         SECTION 24.  Notices.

         All notices and other communications required or permitted hereunder
shall be in writing and shall be deemed given when (a) delivered personally, (b)

          remaining portion of the payment will be in Stock. AT&T stock units

          based upon shares of Stock ("Company RSUs"), as described in the
          Merger Agreement.

                (b) 1997 Grant:

                       (i) The Company RSUs and AT&T stock units shall vest and

                  Company RSUs and cash in respect of the AT&T stock units,

                  common stock on the day immediately prior to the Payment Date.

                       (iii) If the dollar value of the payment (determined by
                  adding the cash payment in respect of the AT&T stock units to

                  Payment Date, of the Stock paid with respect to the Company
                  RSUs) is less than $10,000,000, then the Executive will
                  receive in cash the excess of $10,000,000 over such dollar
                  value; provided that the calculation of Fair Market Value
                  shall not include any amounts attributable to dividends paid
                  with respect to such stock.

                (c) 2001 Grant: Pursuant to the terms of the Broadband
          Adjustment Plan, the 2001 grant shall vest in full and become payable
          as of the Effective Date. The form of payout will be Stock in respect
          of the Company RSUs, and cash in respect of the AT&T stock units,
          based, in the latter case, on the Fair Market Value of AT&T common
          stock on November 15, 2002.

           3.   Stock Options

                (a) The Executive shall receive an award under the Broadband
          Adjustment Plan for a certain number of options to purchase Broadband
          common stock, which shall be converted automatically into options to



                                       B-2



         purchase shares of Stock, as described in the EBA and the Merger
         Agreement.

          granted prior to December 19, 2001 shall vest in full as of the
          Effective Date and shall remain exercisable for the remainder of their
          original terms.

          terms.

           4.   Change in Control

         If an award described in Exhibit B of this Agreement is to be
determined by reference to AT&T shares, then such award shall vest and become
exercisable and be paid out, as the case may be, upon a Change in Control of
AT&T (substituting "AT&T" for the "Company" in the definition of Change in
Control). If an award described in Exhibit B of this Agreement is to be

                                       7


            (c) From the Effective Date until the 2005 Annual Meeting, the
Consultant shall be entitled to participate in each of the Company's executive

                (i) the Consultancy Fee through the end of the month in which
          his death occurs;

                (ii) all outstanding options, whether or not then exercisable,

          their originally scheduled ten-year terms; and

                (iii) all outstanding performance shares and other equity-based
          awards shall vest and be paid out (at target, with respect to the
          performance shares) in a single installment promptly after his death.



                                       8


            (b) Termination Due to Disability. In the event that the

                (iii) all outstanding performance shares and other equity-based
          awards shall vest and be paid out (at target, with respect to the
          performance shares) in a single installment promptly after his
          termination.

                  In no event shall a termination  of the  Consultant's  service
for  Disability  occur until the Party  terminating  his service  gives  written
notice to the other Party in accordance with Section 23 below.

            (c)   Termination by the Company for Cause.

                (i) A termination for Cause shall not take effect unless the
          provisions of this paragraph (i) are complied with. The Consultant
          shall be given written notice by the Board, authorized by a vote of no
          less than 75% of the Board, of the intention to terminate him for
          Cause, such notice (A) to state in detail the particular act or acts
          or failure or failures to act that constitute the grounds on which the
          proposed termination for Cause is based and (B) to be given within six
          months of the Board learning of such act or acts or failure or
          failures to act. The Consultant shall have ten calendar days after the
          date that such written notice has been given to the Consultant in
          which to cure such conduct, to the extent such cure is possible. If he
          fails to cure such conduct, the Consultant shall then be entitled to a
          hearing before the Board. Such hearing shall be held within 15
          calendar days of such notice to the Consultant, provided he requests
          such hearing within ten calendar days of the written notice from the
          Board of the intention to terminate him for Cause. If, within five
          calendar days following such hearing, the Consultant is furnished
          written notice by the Board confirming that, in its judgment, grounds
          for Cause on the basis of the original notice exist, he shall
          thereupon be terminated for Cause.

                (ii) In the event the Company terminates the Consultant's
          service for Cause:


                                       9


                       (A) the Consultant  shall be entitled to the  Consultancy
                  Fee through the date of the termination; and

                       (B) all outstanding options which are not exercisable
                  shall be forfeited; exercisable options shall remain
                  exercisable until the earlier of the ninetieth day after the
                  date of termination or the originally scheduled expiration
                  date of the options unless the Board determines otherwise.

            (d) Termination without Cause or Constructive Termination without
Cause. In the event the Consultant's service is terminated by the Company

Constructive Termination without Cause, the Consultant shall be entitled to the

                (i) the Consultancy Fee through the date of termination;

                (ii) a cash payment of $1,800,000, payable in a single
          installment promptly after his termination;

                (iii) all outstanding options, whether or not then exercisable,
          shall become exercisable and shall remain exercisable until the end of
          their originally scheduled ten-year terms;

                (iv) all outstanding performance shares and other equity-based
          awards shall vest and be paid out (at target, with respect to the
          performance shares) in a single installment promptly after his
          termination; and

                (v) if such termination occurs on or prior to the second
          anniversary of the effective date of the Employment Agreement, the
          Consultant shall be entitled to receive a lump sum cash amount equal
          to the greater of (A) (X) the product of three multiplied by the sum
          of (I) the Base Salary (as defined in the Employment Agreement), (II)
          the annual incentive award, equal to the target bonus established by
          AT&T for 2002, which was 150% of such Base Salary, and (III) the
          long-term performance share award, equal to the performance share
          target set by AT&T for 2002 and (B) the product of four multiplied by
          the sum of Base Salary (as defined in the Employment Agreement), at
          the annualized rate in effect on the date of termination of employment
          under the Employment Agreement, and the Target Bonus (as defined in
          the Employment Agreement) for the year in which the termination of
          employment under the Employment Agreement occurs. If such termination
          occurs after the second anniversary


                                       10


          of the effective date of the Employment Agreement, the Consultant
          shall be entitled to receive the payment set forth in clause (B) of
          this Section 8(d)(v).

          (e) Gross-up Payment.

                (i) If the aggregate of all payments or benefits made or
          provided to the Consultant under this Agreement and under all other
          plans and programs of the Company (the "Aggregate Payment") is
          determined to constitute a Parachute Payment within the meaning of
          Section 280G(b)(2) of the Code, the Company shall pay to the
          Consultant, prior to the time any excise tax imposed by Section 4999
          of the Code ("Excise Tax") is payable with respect to such Aggregate
          Payment, an additional amount (the "Gross-Up Payment") which, after
          the imposition of all income, employment, excise and other taxes
          thereon, is equal to the Excise Tax on the Aggregate Payment. The
          determination of whether the Aggregate Payment constitutes a Parachute
          Payment and, if so, the amount to be paid to the Consultant and the
          time of payment pursuant to this Section 8(e)(i) shall be made by an
          independent auditor (the "Auditor") selected by the Parties and paid
          by the Company. The Auditor shall be a nationally recognized United
          States public accounting firm which has not, during the two years
          preceding the date of its selection, acted in any way on behalf of the
          Company or any Affiliate thereof. If the Consultant and the Company
          cannot agree on the firm to serve as the Auditor, then the Consultant
          and the Company shall each designate one accounting firm and those two
          firms shall jointly select the accounting firm to serve as the
          Auditor. All fees and expenses of the Auditor shall be borne solely by
          the Company. Any Gross- Up Payment shall be paid by the Company to the
          Consultant within five calendar days of the receipt of the Auditor's
          determination. Any determination by the Auditor shall be binding upon
          the Company and the Consultant.

                (ii) As a result of uncertainty in the application of Sections
          280G and 4999 of the Code at the time of the initial determination by
          the Auditor hereunder, it is possible that the Gross-Up Payment made
          will have been an amount more than the Company should have paid
          pursuant to Section 8(e)(i) (the "Overpayment") or that the Gross-Up
          Payment made will have been an amount less than the Company should
          have paid pursuant to Section 8(e)(i) (the "Underpayment"). In the
          event that there is a final determination by the Internal Revenue
          Service, or a final determination by a court of competent
          jurisdiction, that an Overpayment has been made, any such Overpayment
          shall be treated for all purposes as a loan to the Consultant which
          the Consultant shall repay to the Company



                                       11



          together with interest at the applicable Federal rate provided for in
          Section 7872(f)(2) of the Code. In the event that there is a final
          determination by the Internal Revenue Service, a final determination
          by a court of competent jurisdiction or a change in the provisions of
          the Code or regulations pursuant to which an Underpayment arises under
          this Agreement, any such Underpayment shall be promptly paid by the
          Company to or for the benefit of the Consultant together with interest
          at the applicable Federal rate provided for in Section 7872(f)(2) of
          the Code.

                (iii) The Consultant shall notify the Company in writing of any
          claim by the Internal Revenue Service that, if successful, would
          result in an Underpayment and would require the payment by the Company
          of an additional Gross-Up Payment. Such notification shall be given as
          soon as practicable but no later than 10 business days after the
          Consultant is informed in writing of such claim and shall apprise the
          Company of the nature of such claim and the date on which such claim
          is requested to be paid. The Consultant shall not pay such claim prior
          to the expiration of the 30 calendar day period following the date on
          which the Consultant gives such notice to the Company (or such shorter
          period ending on the date that any payment of taxes with respect to
          such claim is due). If the Company notifies the Consultant in writing
          prior to the expiration of such period that it desires to contest such
          claim, the Consultant shall:

                       (A) give the Company any information reasonably requested
                  by the Company relating to such claim,

                       (B) take such action in connection with contesting such
                  claim as the Company shall reasonably request in writing from
                  time to time, including, without limitation, accepting legal
                  representation with respect to such claim by an attorney
                  reasonably selected by the Company,

                       (C) cooperate with the Company in good faith in order
                  effectively to contest such claim, and

                       (D) permit the Company to participate in any proceeding
                  relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Consultant harmless, on an
after-tax basis, for any Excise Tax or income or employment tax (including
interest and penalties with respect thereto) imposed as a result of such
proceeding and



                                       12


payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 8(e), the Company shall control all proceedings taken in connection
with such contest, provided that the Company's control of the contest shall be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Consultant shall be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

            (f) Other Termination Benefits. In the case of any of the foregoing
terminations the Consultant or his estate shall also be entitled to:

                (i) the balance of any incentive awards due for performance

                                       13


            (g) No Mitigation; No Offset. In the event of any termination of
service under this Section 8, the Consultant shall be under no obligation to
seek other employment and there shall be no offset against amounts due the
Consultant under this Agreement on account of any remuneration attributable to
any subsequent employment that he may obtain.

            (h) Nature of Payments. Any amounts due under this Section 8 are in
the nature of severance payments considered to be reasonable by the Company and
are not in the nature of a penalty.

         SECTION 9.  Confidential Information; Prohibited Public Statements;
Publicity.

            (a) The Company (as hereinafter specially defined for purposes of
Sections 9 through 11 hereof), pursuant to the Consultant's performance of
consulting services hereunder, provides the Consultant access to and confides in
him business methods and systems, techniques and methods of operation developed
at great expense by the Company ("Trade Secrets") and which the Consultant
recognizes to be unique assets of the Company's business. The Consultant shall
not, during or at any time after the Term, directly or indirectly, in any manner
utilize or disclose to any person, firm, corporation, association or other
entity, except (i) where required by law, (ii) to directors, consultants or
employees of the Company in the ordinary course of his duties or (iii) during
his performance of consulting services as a consultant or serving as a member of
the Board for such use and disclosure as he shall reasonably determine to be in
the best interest of the Company: (A) any such Trade Secrets, (B) any sales
prospects, customer lists, products, research or data of any kind, or (C) any
information relating to strategic plans, sales, costs, profits or the financial
condition of the Company or any of its customers or prospective customers, which
are not generally known to the public or recognized as standard practice in the
industry in which the Company shall be engaged. The Consultant further covenants
and agrees that he will promptly deliver to the Company all tangible evidence of
the knowledge and information described in (A), (B) and (C), above, prior to or
at the termination of the Consultant's service. For purposes of Sections 9, 10
and 11 hereof the term "Company" shall mean Comcast Corporation ("Comcast") as
well as (I) each of its more than fifty percent (50%) owned subsidiaries and
(II) each other entity in which Comcast directly or indirectly has a greater
than ten percent (10%) equity interest, the fair market value of which interest
is in excess of $50,000,000. In determining Comcast's equity interest for
purposes of this definition, any equity interest which Comcast has an option to
purchase shall be considered as owned by Comcast.



                                       14


            (b) Neither the Consultant nor the Company, its officers or
directors (collectively, the "Company Affiliated Entities") shall, either during
or at any time after the Term, directly or indirectly make any public statement
(including a private statement reasonably likely to be repeated publicly)
reflecting adversely on the Company Affiliated Entities or the Consultant, as
the case may be, or the business prospects of the Company, except for (a) such
statements which the Consultant may be required to make in the ordinary course
of his position as senior consultant to the Company or (b) with respect to each
of the Consultant and the Company Affiliated Entities, as otherwise required by
applicable law.

            (c) Neither the Consultant nor the Company Affiliated Entities shall
comment (including private statements reasonably likely to be repeated publicly)
on, or discuss the circumstances surrounding, this Agreement, except as mutually
agreed or as required by applicable law.

         SECTION 10.  Noncompetition, Noninterference and Nonsolicitation.

            (a) Subject to the geographic limitation of Section 10(b) hereof,
the Consultant, for the period beginning on the Effective Date and ending on the
Termination Date, shall not, directly or indirectly, on his behalf or on behalf
of any other person, firm, corporation, association or other entity, as an
employee or otherwise, engage in, or in any way be concerned with or negotiate
for, or acquire or maintain any ownership interest in any business or activity
which is the same as or competitive with that conducted by the Company at the
termination of his employment, or which was engaged in or developed by the
Company at any time during the term of the Employment Agreement for specific
implementation in the immediate future by the Company.

            (b) The Consultant acknowledges that the Company is engaged in
business throughout the United States and in various foreign countries and that
the Company intends to expand the geographic scope of its activities.
Accordingly and in view of the nature of his position and responsibilities, the
Consultant agrees that the provisions of this Section shall be applicable to
each state and each foreign country, possession or territory in which the
Company may be engaged in business during the Term or the term of the Employment
Agreement, or, with respect to the Consultant's obligations following
termination of his employment under the Employment Agreement, at the termination
of his service or at any time within the twelve-month period following the
effective date of his termination of employment under the Employment Agreement.

            (c) The Consultant agrees that, for the period beginning on the
Effective Date and ending on the Termination Date, the Consultant will not,
directly or indirectly, for himself or on behalf of any third party at any time
in any manner,



                                       15


request or cause any of the Company's customers to cancel or terminate any
existing or continuing business relationship with the Company; solicit, entice,
persuade, induce, request or otherwise cause any employee, officer or agent of
the Company (other than clerical employees of the Company) to refrain from
rendering services to the Company or to terminate his or her relationship,
contractual or otherwise, with the Company; induce or attempt to influence any
supplier to cease or refrain from doing business or to decline to do business
with the Company; divert or attempt to divert any supplier from the Company; or
induce or attempt to influence any supplier to decline to do business with any
businesses of the Company as such businesses are constituted immediately prior
to the termination of employment under the Employment Agreement.

            (d) The Consultant agrees that, for the period beginning on the
Effective Date and ending on the Termination Date, the Consultant will not
directly or indirectly, for himself or on behalf of any third party, solicit for
business in competition with the business of the Company, accept any business in
competition with the business of the Company from or otherwise do, or contract
to do, business in competition with the business of the Company with any person
or entity who, at the time of, or any time during the twelve (12) months
preceding such termination, was an active customer or was actively solicited by
the Company according to the books and records of the Company and within the
knowledge, actual or constructive, of the Consultant.

            (e) Notwithstanding anything to the contrary in this Section 10, the
prohibitions and agreements contained in subsections 10(a), 10(c), and 10(d)
shall terminate immediately upon any termination of Consultant's service
hereunder following a Change in Control.

            (f) Notwithstanding the foregoing, if, following the Term, the
Consultant engages in any behavior that would be prohibited under this Section,
as determined by the Company in its sole discretion, the Company shall be
relieved of its obligations under Section 8(f)(iv) of this Agreement.

            (g) Nothing in this Section 10 shall prohibit the Consultant from
being a passive owner of not more than one percent of the outstanding common
stock, capital stock and equity of any firm, corporation, or enterprise so long
as the Consultant has no active participation in the management of the business
of such firm, corporation or enterprise.

         SECTION 11.  Equitable Remedies.

         The Consultant acknowledges that his compliance with the covenants in
Sections 9 and 10 of this Agreement is necessary to protect the good will and



                                       16


other proprietary interests of the Company and that, in the event of any
violation by the Consultant of the provisions of Section 9 or 10 of this
Agreement, the Company will sustain serious, irreparable and substantial harm to
its business, the extent of which will be difficult to determine and impossible
to remedy by an action at law for money damages. Accordingly, the Consultant
agrees that, in the event of such violation or threatened violation by the
Consultant, the Company shall be entitled to any injunction before trial from
any court of competent jurisdiction as a matter of course and upon the posting
of not more than a nominal bond in addition to all such other legal and
equitable remedies as may be available to the Company. The Consultant further
agrees that, in the event any of the provisions of Sections 9 and 10 of this
Agreement are determined by a court of competent jurisdiction to be contrary to
any applicable statute, law or rule, or for any reason to be unenforceable as
written, such court may modify any of such provisions so as to permit
enforcement thereof as thus modified.

         SECTION 12.  Resolution of Disputes.

         Except as provided in Section 11, any disputes arising under or in
connection with this Agreement shall be resolved by third party mediation of the
dispute and, failing that, by binding arbitration, to be held in a location
mutually agreed to by the Parties, in accordance with the rules and procedures
of the American Arbitration Association. Judgment upon the award rendered by the
arbitrator(s) may be entered in any court having jurisdiction thereof. Each
Party shall bear his or its own costs of the mediation, arbitration or
litigation, except that the Company shall bear all such costs if the Consultant
prevails in such mediation, arbitration or litigation on any material issue.

         SECTION 13.  Indemnification.

            (a) The Company agrees that if the Consultant is made a party, or is
threatened to be made a party, to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding"), by reason of the
fact that he is or was a director, officer or employee of the Company or is or
was serving at the request of the Company as a director, officer, member,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, including service with respect to employee benefit plans,
whether or not the basis of such Proceeding is the Consultant's alleged action
in an official capacity while serving as a director, officer, member, employee
or agent, the Consultant shall be indemnified and held harmless by the Company
to the fullest extent legally permitted or authorized by the Company's
certificate of incorporation or bylaws or resolutions of the Board or, if
greater, by the laws of the Commonwealth of Pennsylvania, against all cost,
expense, liability and loss (including, without limitation, attorney's fees,
judgments, fines, ERISA excise taxes or other



                                       17


liabilities or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by the Consultant in connection therewith, and
such indemnification shall continue as to the Consultant even if he has ceased
to be a director, member, employee or agent of the Company or other entity and
shall inure to the benefit of the Consultant's heirs, executors and
administrators. The Company shall advance to the Consultant all reasonable costs
and expenses incurred by him in connection with a Proceeding within 20 calendar
days after receipt by the Company of a written request for such advance. Such
request shall include an undertaking by the Consultant to repay the amount of
such advance if it shall ultimately be determined that he is not entitled to be
indemnified against such costs and expenses.

            (b) Neither the failure of the Company (including its board of
directors, independent legal counsel or shareholders) to have made a
determination prior to the commencement of any Proceeding concerning payment of
amounts claimed by the Consultant under Section 13(a) above that indemnification
of the Consultant is proper because he has met the applicable standard of
conduct, nor a determination by the Company (including its board of directors,
independent legal counsel or shareholders) that the Consultant has not met such
applicable standard of conduct, shall create a presumption that the Consultant
has not met the applicable standard of conduct.

            (c) The Company agrees to continue and maintain a directors' and
officers' liability insurance policy covering the Consultant which is no less
favorable than the policy covering senior officers of the Company.

         SECTION 14. Assignability; Binding Nature. This Agreement shall be
binding upon and inure to the benefit of the Parties and their respective
successors, heirs (in the case of the Consultant) and assigns. Rights or
obligations of the Company under this Agreement may be assigned or transferred
by the Company pursuant to a merger or consolidation in which the Company is not
the continuing entity, or the sale or liquidation of all or substantially all of
the assets of the Company, provided that the assignee or transferee is the
successor to all or substantially all of the assets of the Company and such
assignee or transferee assumes the liabilities, obligations and duties of the
Company, as contained in this Agreement, either contractually or as a matter of
law. The Company further agrees that, in the event of a sale of assets or
liquidation as described in the preceding sentence, it shall take whatever
action it reasonably can in order to cause such assignee or transferee to
expressly assume the liabilities, obligations and duties of the Company
hereunder. No rights or obligations of the Consultant under this Agreement may
be assigned or transferred by the Consultant other than his rights to
compensation and benefits, which may be transferred only by will or operation of
law.



                                       18



         SECTION 15.  The Consultant's Independence and Discretion.

            (a) Nothing herein contained shall be construed to constitute the
Parties hereto as partners or as joint venturers, or either as agent of the
order, or as employer and employee. By virtue of the relationship described
herein the Consultant's relationship to the Company during the Term shall only
be that of an independent contractor and the Consultant shall perform all
services pursuant to this Agreement as an independent contractor. The Consultant
shall not provide any services under the Company's business name, except as
requested hereunder, and shall not present himself as an employee of the
Company.

            (b) Subject only to such specific limitations as are contained in
this Agreement, the manner, means, details or methods by which the Consultant
performs his obligations under this Agreement shall be solely within the
discretion of the Consultant. The Company shall not have the authority to, nor
shall it, supervise, direct or control the manner, means, details or methods
utilized by the Consultant to perform his obligations under this Agreement and
nothing in this Agreement shall be construed to grant the Company any such
authority.

            (c) To the extent consistent with applicable law, the Company will
not withhold any amounts as federal income tax withholding from wages or as
employee contributions under the Federal Insurance Contributions Act or any
other state or federal laws. The Consultant shall be solely responsible for
payment of any required employment taxes or contributions.

         SECTION 16. Representation. The Company represents and warrants that it
is fully authorized and empowered to enter into this Agreement and that the
performance of its obligations under this Agreement will not violate any
agreement between it and any other person, firm or organization. The Consultant
represents that the performance of his obligations under this Agreement will not
violate any agreement between him and any other person, firm or organization
that would be violated by the performance of his obligations under this
Agreement.

         SECTION 17. Entire Agreement. This Agreement contains the entire
understanding and agreement between the Parties concerning the subject matter
hereof and supersedes all prior agreements, understandings, discussions,
negotiations and undertakings, whether written or oral, between the Parties with
respect thereto, except, without duplication, for those provisions of the
Employment Agreement that would otherwise survive the termination of such
Employment Agreement. The Consultant acknowledges that, except as provided
herein, he shall not be entitled to any other payment, benefits or prerequisites
from the Company or any of its subsidiaries on account of his former employment
by, or his retirement from, the Company, except that the Consultant shall be
entitled



                                       19

to any benefits due to him as a retired employee under the Company's employee
benefit plans.

         SECTION 18. Amendment or Waiver. No provision in this Agreement may be
amended unless such amendment is agreed to in writing and signed by the
Consultant and an authorized officer of the Company. No waiver by either Party
of any breach by the other Party of any condition or provision contained in this
Agreement to be performed by such other Party shall be deemed a waiver of a
similar or dissimilar condition or provision at the same or any prior or
subsequent time. Any waiver must be in writing and signed by the Consultant or
an authorized officer of the Company, as the case may be.

         SECTION 19. Severability. In the event that any provision or portion of
this Agreement shall be determined to be invalid or unenforceable for any
reason, in whole or in part, the remaining provisions of this Agreement shall be
unaffected thereby and shall remain in full force and effect to the fullest
extent permitted by law so as to achieve the purposes of this Agreement.

         SECTION 20. Survivorship. Except as otherwise expressly set forth in
this Agreement, the respective rights and obligations of the Parties hereunder
shall survive any termination of the Consultant's service. This Agreement itself
(as distinguished from the Consultant's service) may not be terminated by either
Party without the written consent of the other Party.

         SECTION 21. References. In the event of the Consultant's death or a
judicial determination of his incompetence, reference in this Agreement to the
Consultant shall be deemed, where appropriate, to refer to his beneficiary,
estate or other legal representative.

         SECTION 22. Governing Law; Jurisdiction. This Agreement shall be
governed in accordance with the laws of the State of New York without reference
to principles of conflict of laws.

         SECTION 23. Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be deemed given when (a)
delivered personally, (b) sent by certified or registered mail, postage prepaid,
return receipt requested or (c) delivered by overnight courier (provided that a
written acknowledgment of receipt is obtained by the overnight courier) to the
Party concerned at the address indicated below or to such changed address as
such Party may subsequently give such notice of:
