Dear Gail:

         The purpose of this letter  agreement  (hereinafter  "Agreement") is to
detail and document a special individual  non-qualified  supplemental retirement
arrangement we have developed for you. Under this Agreement,  a deferred account
(hereinafter   "Deferred  Account")  will  be  established  in  your  name.  The
maintenance,  vesting, forfeiture and distribution of the Deferred Account shall
be in accordance with the following terms and conditions.

         On November 1, 1997  (hereinafter  the  "Effective  Date"),  AT&T Corp.
(hereafter  "the  Company")  shall credit the  Deferred  Account with an initial
balance of Eight Hundred and Twenty  Thousand  Dollars  ($820,000).  The Company
shall  credit  interest to the Deferred  Account as of the end of each  calendar
quarter at a rate equal to one-quarter of the average 30 Year Treasury Bond Rate
in effect for the last previous quarter.

         The Deferred Account will be maintained as a bookkeeping account on the
records of the Company and you will have no present  ownership right or interest
in the Deferred Account,  nor in any assets of the Company with respect thereto.
The Deferred Account may not be assigned,  pledged or otherwise alienated by you
and any attempt to do so, or any garnishment, execution or levy of any kind with
respect to the Deferred Account, will not be recognized.  You shall not have any
right to receive any payment  with respect to the  Deferred  Account,  except as
expressly provided below.

         In the event you cease to be a Company  employee  prior to the  seventh
anniversary of the Effective Date:

                    (a)    by  reason  of  death  or  Long-Term  Disability  (as
                           defined below),  all amounts credited to the Deferred
                           Account through the  date of such  termination, shall
                           be   paid   to  you  [or, upon  your  death  to  your
                           beneficiary,   as   designated  on    a  form   filed
                           with  Executive  Human  Resources,  or to your estate
                           if no beneficiary  has  been designated, (hereinafter
                           your   Survivors)]  within   the   calendar   quarter
                           immediately  following  the  quarter  which  includes
                           the date of  your  termination of Company employment;

                  (b)      by reason of Company-initiated  termination for other

                           to  the   Deferred   Account   through   the  seventh

                           you  (or  to  your  Survivors)  within  the  calendar
                           quarter  immediately   following  the  quarter  which
                           includes such seventh anniversary;

                  (c)      by reason of your election to terminate  your Company
                           employment  for Good Reason (as defined  below),  all
                           amounts  credited to the Deferred Account through the
                           seventh  anniversary  of the Effective  Date shall be
                           paid  to  you  (or  to  your  Survivors)  within  the

                           Deferred Account.

                  moral turpitude;

         (iii)    gross omission or gross  dereliction of any statutory,  common

                  Management Team  or  those of a  similar/replacing  governance
                  body;  provided, however,  that the Company's decision  not to

                  in your  business unit's head  count,  by  themselves,  do not
                  constitute  Good Reason; or

         (ii)     a  reduction  in  your "Total Annual Compensation" (defined as

                  for any calendar or fiscal year, as applicable,  to  an amount

                  value of any special one-time or periodic long-term  incentive
                  grants, and shall be determined by valuing Performance Shares,
                  Stock  Units, Restricted Stock,  Restricted Stock Units, etc.,
                  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 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 such Compensation and Employee Benefits
                  Committee when authorizing such grants.

          It is understood and agreed that you will not talk about,  write about
or otherwise  publicize  the terms or  existence  of this  Agreement or any fact
concerning  its  execution  or  implementation.  You may,  however,  discuss its
contents  with your  spouse,  legal  and/or  financial  counselor.  IN ADDITION,
DEFERRED ACCOUNT AMOUNTS PROVIDED UNDER THIS AGREEMENT ARE SUBJECT TO FORFEITURE
(OR  REPAYMENT IF SUCH  AMOUNTS  ALREADY HAVE BEEN PAID) IF YOU VIOLATE THE AT&T
NON-COMPETITION  GUIDELINE IN EFFECT AT THE TIME OF THE VIOLATION  ANYTIME PRIOR
TO THE THIRD ANNIVERSARY OF YOUR TERMINATION OF COMPANY EMPLOYMENT. (THE CURRENT
GUIDELINE SUMMARY IS ATTACHED.)

         THIS  AGREEMENT  IS  NOT  AN  EMPLOYMENT  CONTRACT  AND  SHOULD  NOT BE
CONSTRUED OR INTERPRETED  AS CONTAINING  ANY GUARANTEE OF CONTINUED  EMPLOYMENT.
THE   EMPLOYMENT   RELATIONSHIP   WITH  THE   COMPANY   IS  BY  MUTUAL   CONSENT
("EMPLOYMENT-AT-WILL").  THIS MEANS THAT  EMPLOYEES  HAVE THE RIGHT TO TERMINATE
THEIR EMPLOYMENT AT ANY TIME AND FOR ANY REASON.  LIKEWISE, THE COMPANY RESERVES
THE RIGHT TO DISCONTINUE  YOUR  EMPLOYMENT WITH OR WITHOUT CAUSE AT ANY TIME AND
FOR ANY REASON.

         Payments  from the Deferred  Account are in addition to and not in lieu
of any qualified or non-qualified  pension,  savings,  or other retirement plan,
program  or  arrangement  covering  you,  nor are such  payments  in lieu of any
payments  or other  benefits  which may be provided to you under the AT&T Senior



Officer  Severance  Plan.  The Deferred  Account  payments  provided  under this
Agreement  are subject to payroll tax  withholding  and  reporting,  and amounts
credited to the Deferred  Account are not  included in the base for  calculating
benefits  under any  employee  or Senior  Management  benefit  plan,  program or
practice.

         Any  dispute,  controversy,  or  question  arising  under,  out of,  or
relating  to this  Agreement  or the  breach  thereof,  shall  be  referred  for
arbitration in the State of New Jersey to a neutral  arbitrator  selected by you
and the Company. The proceeding shall be governed by the Commercial Rules of the
American Arbitration Association then in effect or such rules last in effect (in
the event such  Association  is no longer in existence)  and the decision of the
arbitrator  shall be  governed  by the rule of law. If the parties are unable to
agree upon a neutral  arbitrator  within  thirty  (30) days after each party has
given the other written notice of the desire to submit the dispute,  controversy
or question  for  decision  as  aforesaid,  then  either  party may apply to the
American  Arbitration  Association for the appointment of a neutral  arbitrator,
or, if such  Association  is not then in  existence or does not desire to act in
the matter,  either party may apply to the Presiding Judge of the Superior Court
of any county in New Jersey for the appointment of a neutral  arbitrator to hear
the parties and settle the dispute,  controversy or question,  and such right to
submit a dispute  arising  hereunder  to  arbitration  and the  decision  of the
neutral  arbitrator  shall be final,  conclusive  and binding on all  interested
persons  and  no  action  at  law or in  equity  shall  be  instituted,  or,  if
instituted,  further  prosecuted by either party other than to enforce the award
of the neutral arbitrator.  You and the Company shall each bear all your and its
own costs and attorney fees,  except that the Company shall pay the costs of any
arbitrator appointed hereunder as well as the copy of any official transcript of
the proceeding.

         The  construction,  interpretation  and  performance  of this Agreement
shall be governed by the laws of the State of New Jersey,  without regard to its
conflict of laws rule.

         Gail,  I am  happy to  present  this  special  arrangement  to you.  It
