Non-competition.

In consideration for payments made under this Agreement, including but not
limited to paragraphs 3(a) and 3(b), Executive agrees that he will not, for a
period of One (1) year after his Employment with the Company, establish a
relationship with a competitor (including but not limited to an employment or
consulting relationship) or engage in any activity which is in conflict with or
adverse to the interest of the Company, as defined by the AT&T Non-Competition
Guideline (hereinafter referred to as a "Competitive Activity"). Executive
recognizes that this obligation includes, and is not limited to, an agreement
that he shall not work for a competitor of AT&T Corp. as an executive,
consultant, independent contractor or in any other capacity for a period of One
(1) year following the termination of his employment with the Company,
regardless of whether Executive or the Company terminates the employment
relationship.

In addition to Executive's obligations outlined in paragraph 10(a) of this
Agreement, any and all payments (except those made from Company-sponsored
tax-qualified pension or welfare plans), benefits or other entitlements to which
the Executive may be eligible in accordance with the terms hereof, may be
forfeited, whether or not in pay status, at the discretion of the Company, if
Executive engages in Competitive Activity for a period of Two (2) years
following termination of his Employment from the Company, regardless of whether
Executive or the Company terminates the employment relationship. The payments,
benefits and other entitlements hereunder are being made in part in
consideration of the obligations of this paragraph 10 and in particular the
post-employment payments, benefits and other entitlements are being made in
consideration of, and dependent upon compliance with this paragraph. This
paragraph shall apply notwithstanding any other provision of this Agreement;
provided, however, that compensation awarded to Executive under paragraph 5
shall preclude Executive from Competitive Activity for One (1) year following
the termination of his employment.

No forfeiture or cancellation shall take place under paragraph 10(b) with
respect to any payments, benefits or entitlements hereunder or under any other
award agreement, plan or practice unless the Company shall have first given
Executive written notice of its intent to so forfeit, or cancel or pay out and
Executive has not, within thirty (30) calendar days of giving such notice,
ceased such unpermitted Competitive Activity, provided that the foregoing prior
notice procedure shall not be required with respect to either: (i) a Competitive
Activity which Executive initiated after the Company had informed the Executive
in writing that it believed such Competitive activity violated this paragraph 10
or the AT&T Non-Competition Guideline; or (ii) any Competitive Activity
regarding wireless local, regional or long distance telephone services or other
products or services, including broadband services, which are part of a line of
business which represents more than five percent (5%) of the Company's
consolidated gross revenues for its most recent completed fiscal year prior to
the commencement of the Competitive Activity.

Nothing in this Section 10 shall prohibit the Executive from being a passive
owner of not more than one percent (1%) of the outstanding common
<PAGE>
                                       8


stock, capital stock and equity of any firm, corporation or enterprise so long
as the Executive has no active participation in the management of business of
such firm, corporation or enterprise.

Nothing in this Section 10 or the Non-Competition Guideline shall preclude
Executive from serving on the Board of Directors of a start-up Company ("NewCo")
during the two (2) year period immediately following his last day of employment
with the Company provided that no active and significant competitor of the
Company is an active participant in the management of such NewCo. For purposes
of this Agreement a Company shall cease being a NewCo should its annual revenue
exceed 500 million dollars. Should the annual revenue of NewCo exceed 500
million dollars Executive's relationship with NewCo shall be subject to the Non
Competition Guideline. Nothing in this paragraph shall be deemed to diminish or
reduce the obligations of Executive not to use or disclose the Company's
confidential and proprietary information.

If the restrictions stated herein are found by a court to be unreasonable, the
Parties agree that the maximum period, scope or geographical area reasonable
under such circumstances shall be substituted for the stated period, scope or
area and that the court shall revise the restrictions contained herein to cover
the maximum period, scope and area permitted by law.

Resolution of Disputes. 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 New Jersey, 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. The Company shall pay the costs of the arbitrator or the
mediator but not the legal fees of Executive; provided, however, that the
Company shall bear all such costs if Executive prevails in such arbitration on
any material issue.

Non-Interference. During Executive's employment and for a period of Two (2)
years following the effective date of Executive's termination, for any reason,
from the Company, Executive agrees not to directly or indirectly recruit,
solicit or induce, any employees, consultants or independent contractors of the
Company to terminate, alter or modify their employment or other relationship
with the Company. During Executive's employment and for a period of Two (2)
years following the effective date of Executive's termination, for any reason,
from the Company, Executive agrees not to directly or indirectly solicit any
customer or business partner of the Company or interfere with the Company's
relationships with any of its customers or business partners on behalf of any
enterprise that directly or indirectly competes with the Company.

Injunction. If Executive commits a breach of any of the provisions of Sections 8
through 12 or any part thereof, the Company shall have the right and remedy to
have the provisions of this Agreement specifically enforced by way of
preliminary and/or permanent injunction by any court having jurisdiction, it
being acknowledged and agreed by Executive and Company that any such breach will
cause irreparable injury to the Company and that money damages will not provide
an adequate remedy to the Company. Furthermore, this Agreement is intended to
protect the proprietary rights of
<PAGE>
                                       9


the Company in important ways, and even the threat of any misuse of the
technology or other confidential information of the Company would be irreparably
harmful because of the importance of that technology and confidential
information. In light of these considerations, Executive agrees that a court of
competent jurisdiction should immediately enjoin any breach or threatened breach
of paragraphs 8 through 12 of this Agreement, upon Company's request, and the
Company is released from the requirement of posting any bond in connection with
temporary or preliminary injunctive relief, to the extent permitted by law. Such
right to injunctive relief shall be in addition to, and not in lieu of, any
other rights and remedies available to the Company under law or in equity.

Company Initiated Termination of Employment or Good Reason Termination. Should
the Company terminate Executive's employment without Cause or should Executive
terminate his employment for Good Reason, Executive will receive a payment
equivalent to payments to which other similarly situated Company executives
would be entitled at the time of the termination of his employment under the
terms of the Senior Officer Separation Plan. This payment shall be payable to
Executive within ninety (90) days of his last day of employment with the
Company. For termination by Executive for Good Reason or by the Company without
Cause, Executive shall also be entitled to the following: (a) accelerated
vesting of Stock Options, Restricted Shares and Restricted Stock Units in
accordance with the terms under which the grants were made; (b) payment of
Annual Bonus in the target amount for the year in which the termination occurs,
prorated to reflect length of employment during that year; (c) outstanding
Performance Shares shall continue to vest; (d) immediate vesting of the Special
Deferral Account set forth in paragraph 5(c); (e) payment to Executive of any
unpaid hiring bonus under paragraphs 5(c) and 5(d)(ii) of this Agreement; (f)
payment of the Special Individual Pension Arrangement in accordance with its
terms and reflecting the amount accrued as of the date of termination of
Executive's employment; (g) coverage for himself and eligible dependents under
the Senior Management Separation Medical Plan; (h) continuation of Senior
Management Universal Life Insurance; and (i) financial counseling for one year,
including income tax return preparation for year of termination and a federal
tax allowance to Executive for the cost of the financial counseling.

Termination for Cause and Good Reason. For purposes of this Agreement, "Cause"
and "Good Reason" shall be defined as follows:

                  (a) Cause shall mean: (1) conviction (including a plea of
         guilty or nolo contendere) of a felony or any crime or theft,
         dishonesty or moral turpitude; or (2) gross omission or gross
         dereliction of any statutory or common law duty of loyalty to the
         Company; or (3) violation of AT&T's Code of Conduct.

                  (b) "Good Reason" shall mean any termination of Executive's
         Company employment, initiated by Executive, resulting from any of the
         following events without Executive's express written consent, which are
         not cured by the Company within twenty (20) days of Executive giving
         the Company written notice thereof:

                  (i) Executive's demotion to a position which is not of a rank
                  and responsibility comparable to members of the
<PAGE>
                                       10


                  current Operations Group or those of a successor governance
                  body; provided, however, that the Company's decision not to
                  continue an Operations Group shall not be Good Reason, and
                  provided, further, that (1) changes in reporting relationships
                  shall not, alone, constitute Good Reason, unless such change
                  results in the Executive reporting to someone other than the
                  Company's Chief Executive Officer (or similar office), and/or
                  (2) a reduction in the Company's budget or employee head
                  count, without more, do not constitute Good Reason, or

                  (ii) A reduction in Executive's "Total Annual Compensation"
                  (defined as the sum of Executive's Annual Base Salary Rate,
                  Target Annual Incentive and "Target Annual Long Term Incentive
                  Grants") for any calendar or fiscal year, as applicable, to an
                  amount that is less than the Total Annual Compensation that
                  existed in the prior calendar or fiscal year, as applicable.
                  For purposes of this Paragraph the dollar value of the "Target
                  Annual Long Term Incentive Grants" shall exclude the value of
                  any special one-time or periodic long-term incentive grants,
                  and shall be determined by valuing Performance Shares, Stock
                  Units, Restricted Stock and stock options, Restricted Stock
                  Units at the market share price utilized in valuing the annual
                  Senior Management compensation structures in the materials
                  presented to the Compensation and Employee Benefits Committee
                  of the Company's Board of Directors ("the Committee") when
                  authorizing such grants, and assuming 100% performance
                  achievement if such grants include performance criteria. Stock
                  Options and Stock Appreciation Rights will be valued by the
                  Black-Scholes methodology (and related share price) as
                  utilized in the materials presented to the Committee when
                  authorizing such grants.

Termination Without Good Reason or For Cause. Should Executive leave his
employment without Good Reason ("Voluntary Termination"), Executive shall
receive nothing further under this Agreement except for (i) Stock Options,
Performance Shares, Restricted Shares and Restricted Stock Units already vested
and (ii) benefits in the then-applicable Senior Management Separation Medical
Plan but only if Voluntary Termination occurs after December 31, 2002. In the
event of a Voluntary Termination, Executive's Stock Options, Performance Shares,
Restricted Shares and Restricted Stock Units awarded but not vested shall be
cancelled. If Executive is terminated for Cause at any time during this

his termination and all Stock Options, Performance Shares, Restricted Shares and
Restricted Stock Units vested but not exercised shall be cancelled.

Special Voluntary Termination. If Executive resigns after December 31, 2002 and,
at the time of resignation, C. Michael Armstrong is no longer the Chief
Executive Officer of the Company and Executive has not been appointed to

the position of Chief Executive Officer ("Special Voluntary Termination"),
Executive shall be entitled to the benefits set forth in paragraph 16 as well as
an accelerated vesting of Stock Options, Restricted Shares and Restricted Stock

<PAGE>
                                       12


inability of Executive to perform his duties under this Agreement by reason of
any physical or mental impairment that is expected to prevent Executive from
performing his duties for a period exceeding twelve (12) months. Provided,
however, that nothing in this paragraph or this Agreement shall prevent the
Company from reassigning Executive's job duties on a temporary basis during any
period in which the Executive is receiving benefits under the Company's
applicable short-term disability benefits plan until the Executive returns to
work full-time or is terminated due to Disability.

Loan Repayment. Upon death, disability or termination of employment, for any
reason, Executive or Executive's estate must repay all outstanding loans within
ninety (90) days of the last day of employment.

or Advisory Committees of other companies in positions held prior to the
Execution Date assuming that the other company is not a competitor of the
Company as determined by the Secretary of the Company's Board of Directors.
Executive agrees to provide a list, as soon a practicable following the
Execution Date, of such Board and Committee memberships so that the Company may
make such determination.

Other Terms.

 This Agreement shall be governed by and construed and enforced in accordance
with the laws of the State of New Jersey, without regard to conflict of law
rules. If any provision of this Agreement is hereafter construed to be invalid
or unenforceable in any respect, the same shall not affect the remaining
provisions of this Agreement, without regard to the invalid portion, and any
such invalid provisions shall be reformed and construed to the extent necessary
to permit their enforceability so as to reflect the intent of the parties
hereto.

 Executive hereby represents and warrants that (i) Executive has the right to
enter into this Agreement with the Company and to grant the rights contained in
this Agreement, and (ii) the provisions of this Agreement do not violate any
other contracts or agreements that the Executive has entered into with any other
individual or entity.

Executive agrees that the terms of this Agreement are reasonable and properly
required for the protection of the Company's legitimate business interests. If
any of the covenants or provisions contained in this Agreement, or any part
thereof, is hereafter construed to be invalid or unenforceable in any respect,
the same shall not affect the remainder of the covenant, covenants or provisions
which shall be given the maximum effect possible without regard to the invalid
portions and the remainder shall then be fully enforceable.

The article headings contained herein are for reference purposes only and shall
not in any way affect the meaning or interpretation of this Agreement.

This Agreement sets forth the entire agreement and understanding of the Parties
relating to the subject matter hereof, and supersedes all prior agreements,
arrangements and understandings, written or oral, relating to the subject matter
hereof.

This Agreement may not be amended, modified, superseded or waived, except by a
written instrument executed by both Parties hereto, or, in the case of a waiver,
by the party waiving compliance. The failure of either Party at any time or
times to require performance of any provision hereof shall in no manner affect
the right at a later time to enforce the same. No waiver by either Party of the
breach of any term or covenant contained in this Agreement whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.

Duration of Terms. The respective rights and obligations of the parties
hereunder shall survive any termination of Executive's employment or this
Agreement to the extent necessary to the intended preservation of such rights
and obligations.

Acknowledgment. Executive acknowledges that before signing this Agreement,
Executive was given the opportunity to read it, evaluate it and discuss it with
Executive's personal advisors, Executive's attorney and with representatives of
the Company. Executive further acknowledges that the Company has not provided
Executive with any legal advice regarding this Agreement.

Assignment. The Company specifically reserves the right to assign the terms of
this Agreement to any successor, whether the successor is the result of any
sale, purchase, merger, consolidation, asset sale, divestiture or spin-off or
any form or combination thereof. No sale, purchase, merger, consolidation, asset
sale, divestiture or spin-off or any form or combination thereof shall be
construed as a termination of Executive's employment and will not trigger the
Company's obligations under paragraphs 14, 16 or 17 of this Agreement.

Release for Severance Payments. The Company shall be required to pay Executive
payments upon the termination of his employment as provided under this Agreement
only if Executive executes a release upon his termination releasing the Company
from any liability arising from his employment or termination thereof. This
release shall include, but not be limited to, claims for breach of contract or
those arising under state and federal employment statutes, including but not
limited to, the Civil Rights Act of 1964, as amended ("Title VII"), and the Age
Discrimination in Employment Act.
