similar transaction or other change in corporate structure affecting the Shares,
such adjustments and other substitutions shall be made to the Plan and to Awards
as  the  Committee  in its  sole  discretion  deems  equitable  or  appropriate,
including without limitation such adjustments in the aggregate number, class and
kind of securities which may be delivered under the Plan, in the aggregate or to
any one Participant,  in the number, class, kind and option or exercise price of
securities subject to outstanding  Options,  Stock Appreciation  Rights or other
Awards granted under the Plan,  and in the number,  class and kind of securities
subject to Awards  granted under the Plan  (including,  if the  Committee  deems
appropriate,  the  substitution of similar options to purchase the shares of, or
other awards denominated in the shares of, another company) as the Committee may
determine to be appropriate in its sole discretion,  provided that the number of
Shares subject to any Award shall always be a whole number.

    SECTION 5. ELIGIBILITY.  Any  Employee shall be eligible to be selected as a
Participant.

    SECTION 6. STOCK OPTIONS.  Options may be granted  hereunder to Participants
either alone or in addition to other Awards  granted under the Plan.  Any Option

the Committee may from time to time approve. Any such Option shall be subject to
the following terms and conditions and to such additional  terms and conditions,
not  inconsistent  with the provisions of the Plan, as the Committee  shall deem
desirable:

    (a) OPTION PRICE. The purchase  price per Share purchasable  under an Option
shall be  determined  by the Committee in its sole  discretion;  provided  that,
except in the case of  Substitute  Awards or in  connection  with an  adjustment
provided for in Section  4(d),  such  purchase  price shall not be less than the
Fair Market Value of the Share on the date of the grant of the Option.

    (b) OPTION  PERIOD.  The term of each Option shall be fixed by the Committee
in its  sole  discretion;  provided  that no  Incentive  Stock  Option  shall be
exercisable  after  the  expiration  of ten  years  from the date the  Option is
granted.



    (c)  EXERCISABILITY.  Options shall be  exercisable at such time or times as
determined by the Committee at or subsequent to grant.

    (d) METHOD OF EXERCISE.  Subject to the other  provisions  of the Plan,  any
Option may be exercised by the  Participant  in whole or in part at such time or
times,  and the Participant may make payment of the option price in such form or
forms,  including,  without  limitation,  payment by delivery of cash, Shares or
other  consideration  (including,  where  permitted  by law and  the  Committee,
Awards)  having a Fair  Market  Value on the  exercise  date  equal to the total
option price, or by any combination of cash,  Shares and other  consideration as
the Committee may specify in the applicable Award Agreement.

    (e)  INCENTIVE  STOCK  OPTIONS.  In  accordance  with  rules and  procedures
established  by the Committee,  and except as otherwise  provided in Section 11,
the  aggregate  Fair Market  Value  (determined  as of the time of grant) of the
Shares with respect to which  Incentive  Stock  Options held by any  Participant
which are exercisable for the first time by such Participant during any calendar
year under the Plan (and  under any other  benefit  plans of the  Company or any
Subsidiary) shall not exceed $100,000 or, if different,  the maximum  limitation
in effect at the time of grant under  Section 422 of the Code,  or any successor
provision,  and any regulations promulgated thereunder.  Incentive Stock Options
shall be granted  only to  participants  who are  employees  of the Company or a
Subsidiary  of the Company.  The terms of any  Incentive  Stock  Option  granted
hereunder shall comply in all respects with the provisions of Section 422 of the
Code, or any successor provision, and any regulations promulgated thereunder.

    (f) FORM OF SETTLEMENT.  In its sole discretion,  the Committee may provide,
at the time of grant,  that the Shares to be issued  upon an  Option's  exercise
shall be in the form of  Restricted  Stock or other similar  securities,  or may
reserve the right so to provide after the time of grant.

    SECTION 7.  STOCK  APPRECIATION  RIGHTS.  Stock  Appreciation  Rights may be
granted  hereunder to  Participants  either alone or in addition to other Awards
granted  under the Plan and may,  but need  not,  relate  to a  specific  Option
granted under Section 6. The provisions of Stock Appreciation Rights need not be
the same with respect to each recipient. Any Stock Appreciation Right related to
a  Nonstatutory  Stock  Option may be  granted  at the same time such  Option is
granted or at any time thereafter  before exercise or expiration of such Option.
Any Stock  Appreciation  Right  related to an  Incentive  Stock  Option  must be
granted  at the same  time  such  Option  is  granted.  In the case of any Stock
Appreciation  Right  related  to any  Option,  the Stock  Appreciation  Right or
applicable portion thereof shall terminate and no longer be exercisable upon the
termination or exercise of the related Option,  except that a Stock Appreciation
Right  granted with respect to less than the full number of Shares  covered by a
related  Option shall not be reduced  until the exercise or  termination  of the
related   Option  exceeds  the  number  of  Shares  not  covered  by  the  Stock
Appreciation  Right. Any Option related to any Stock Appreciation Right shall no
longer be  exercisable  to the extent the related Stock  Appreciation  Right has
been exercised.  The Committee may impose such conditions or restrictions on the
exercise of any Stock Appreciation Right as it shall deem appropriate.

    SECTION 8.  RESTRICTED STOCK.

    (a)  ISSUANCE.  A  Restricted  Stock Award shall be subject to  restrictions
imposed by the Committee during a period of time specified by the Committee (the
"Restriction  Period").  Restricted  Stock  Awards  may be issued  hereunder  to
Participants, for no cash consideration or for such minimum consideration as may
be required  by  applicable  law,  either  alone or in addition to other  Awards
granted under the Plan.  The  provisions of Restricted  Stock Awards need not be
the same with respect to each recipient.


    (b) REGISTRATION.  Any Restricted Stock issued hereunder may be evidenced in
such manner as the  Committee  in its sole  discretion  shall deem  appropriate,
including,  without limitation,  book-entry  registration or issuance of a stock
certificate  or  certificates.  In the event any stock  certificate is issued in
respect of shares of Restricted  Stock awarded under the Plan, such  certificate
shall  be  registered  in the  name  of  the  Participant,  and  shall  bear  an
appropriate  legend  referring  to  the  terms,  conditions,   and  restrictions
applicable to such Award.

    (c) FORFEITURE.  Except as otherwise determined by the Committee at the time
of grant or thereafter, upon termination of employment for any reason during the
restriction  period, all Shares of Restricted Stock still subject to restriction
shall  be  forfeited  by  the   Participant   and  reacquired  by  the  Company.
Unrestricted  Shares,  evidenced  in such  manner as the  Committee  shall  deem
appropriate,  shall be  issued  to the  grantee  promptly  after  the  period of
forfeiture, as determined or modified by the Committee, shall expire.

    (d) MINIMUM VESTING CONDITION.  The minimum Restriction Period applicable to
any  Restricted  Stock  Award  that is not  subject  to  performance  conditions
restricting transfer shall be three (3) years from the date of grant;  provided,
however,  that a Restriction Period of less than three (3) years may be approved
for such Awards with respect to up to five (5) million Shares under the Plan.

    SECTION 9. PERFORMANCE AWARDS. Performance Awards may be issued hereunder to
Participants, for no cash consideration or for such minimum consideration as may
be required  by  applicable  law,  either  alone or in addition to other  Awards
granted  under the Plan.  The  performance  criteria to be  achieved  during any
Performance  Period and the length of the Performance Period shall be determined
by the Committee upon the grant of each Performance Award. Except as provided in
Section 11,  Performance  Awards will be  distributed  only after the end of the
relevant  Performance  Period.  Performance  Awards may be paid in cash, Shares,
other  property  or any  combination  thereof,  in the  sole  discretion  of the
Committee at the time of payment. The performance levels to be achieved for each
Performance  Period  and the  amount  of the  Award to be  distributed  shall be
conclusively  determined by the Committee.  Performance  Awards may be paid in a
lump sum or in installments following the close of the Performance Period or, in
accordance with procedures established by the Committee, on a deferred basis.

    SECTION 10.  OTHER STOCK UNIT AWARDS.

    (a) STOCK AND  ADMINISTRATION.  Other Awards of Shares and other Awards that
are  valued  in whole or in part by  reference  to, or are  otherwise  based on,
Shares or other property ("Other Stock Unit Awards") may be granted hereunder to
Participants,  either  alone or in addition to other  Awards  granted  under the
Plan.  Other Stock Unit Awards may be paid in Shares,  cash or any other form of
property as the  Committee  shall  determine.  Subject to the  provisions of the
Plan,  the  Committee  shall have sole and complete  authority to determine  the
Employees  of the  Company and its  Affiliates  to whom and the time or times at
which such Awards shall be made, the number of Shares to be granted  pursuant to
such Awards,  and all other  conditions of the Awards.  The  provisions of Other
Stock Unit Awards need not be the same with respect to each recipient.

    (b) TERMS AND  CONDITIONS.  Subject to the  provisions  of this Plan and any
applicable Award Agreement,  Awards and Shares subject to Awards made under this
Section  10,  may not be  sold,  assigned,  transferred,  pledged  or  otherwise
encumbered  prior to the date on which the Shares are issued,  or, if later, the
date on which any applicable restriction, performance or deferral period lapses.



For any Award or Shares  subject to any Award  made  under  this  Section 10 the
transferability  of which  is  conditioned  only on the  passage  of time,  such
restriction  period  shall be a minimum  of three (3) years.  Shares  (including
securities convertible into Shares) subject to Awards granted under this Section
10 may be issued for no cash consideration or for such minimum  consideration as
may be required by applicable law. Shares (including securities convertible into
Shares)  purchased  pursuant to a purchase  right  awarded under this Section 10
shall be purchased for such  consideration  as the  Committee  shall in its sole
discretion determine,  which, except in the case of Substitute Awards, shall not
be less than the Fair Market Value of such Shares or other  securities as of the
date such purchase right is awarded.

    SECTION 11.  CHANGE IN CONTROL PROVISIONS.

    (a) IMPACT OF EVENT.  Notwithstanding any other provision of the Plan to the
contrary,  unless the Committee shall  determine  otherwise at the time of grant
with respect to a particular Award, in the event of a Change in Control:

         (i) any Options and Stock  Appreciation  Rights  outstanding  as of the
date such Change in Control is  determined to have  occurred,  and which are not
then  exercisable and vested,  shall become fully  exercisable and vested to the
full extent of the original grant;

         (ii)  the  restrictions  and  deferral  limitations  applicable  to any
Restricted Stock shall lapse, and such Restricted Stock shall become free of all
restrictions  and  limitations  and become fully vested and  transferable to the
full extent of the original grant;

         (iii) all  Performance  Awards  shall be  considered  to be earned  and
payable in full,  and any  deferral  or other  restriction  shall lapse and such
Performance Awards shall be immediately settled or distributed; and

         (iv) The  restrictions  and deferral  limitations and other  conditions
applicable  to any Other Stock Unit Awards or any other Awards shall lapse,  and
such  Other  Stock Unit  Awards or such other  Awards  hall  become  free of all
restrictions, limitations or conditions and become fully vested and transferable
to the full extent of the original grant.

    (b) CHANGE IN CONTROL CASH-OUT.  Notwithstanding  any other provision of the
Plan, during the 60-day period from and after a Change in Control (the "Exercise
Period"), if the Committee shall determine at, or at any time after, the time of
grant, a Participant  holding an Option or Stock  Appreciation  Right shall have
the  right,  whether  or not the  Option  or Stock  Appreciation  Right is fully
exercisable  and in lieu of the  payment  of the  purchase  price for the Shares
being  purchased  under  the  Option or Stock  Appreciation  Right and by giving
notice to the Company, to elect (within the Exercise Period) to surrender all or
part of the Option or Stock  Appreciation  Right to the  Company  and to receive
cash,  within 30 days of such notice,  in an amount equal to the amount by which
the Change in Control Price per Share on the date of such election  shall exceed
the purchase price per Share under the Option or Stock  Appreciation  Right (the
"Spread")  multiplied by the number of Shares  granted under the Option or Stock
Appreciation  right as to which the right granted under this Section 11(b) shall
have been exercised.

    (c)  Notwithstanding  any other provision of this Plan, if any right granted
pursuant to this Plan would make a Change in Control transaction  ineligible for
pooling-of-interests  accounting  under APB No. 16, that (after giving effect to
any other  actions  taken to cause  such  transaction  to be  eligible  for such



pooling-of-interests  accounting  treatment)  but for the  nature of such  right
would otherwise be eligible for such accounting  treatment,  the Committee shall
have the  ability to  substitute  for the cash  payable  pursuant  to such right
Shares  with a Fair  Market  Value  equal to the cash that  would  otherwise  be
payable pursuant thereto.

    SECTION 12.  CODE SECTION 162(m) PROVISIONS.

    (a)  Notwithstanding  any other  provision  of this Plan,  if the  Committee
determines at the time Restricted  Stock, a Performance  Award or an Other Stock
Unit Award is granted to a Participant who is then a Senior Manager or an E band
employee that such  Participant  is, or is likely to be as of the end of the tax
year in which the Company would claim a tax  deduction in  connection  with such
Award, a Covered  Employee,  then the Committee may provide that this Section 12
is applicable to such Award.

    (b) If an  Award  is  subject  to this  Section  12,  then  the  lapsing  of
restrictions  thereon and the  distribution  of cash,  Shares or other  property
pursuant thereto,  as applicable,  shall be subject to the achievement of one or
more objective  performance goals  established by the Committee,  which shall be
based on the  attainment of specified  levels of one or any  combination  of the
following:  net cash provided by operating  activities,  earnings per share from
continuing  operations,  operating  income,  revenues,  gross margin,  return on
operating  assets,   return  on  equity,   economic  value  added,  stock  price
appreciation,  total stockholder  return, or cost control, of the Company or the
Affiliate  or division of the Company  for or within  which the  Participant  is
primarily  employed.   Such  performance  goals  also  may  be  based  upon  the
achievement  of  specified  levels of Company  performance  (or  performance  of
applicable  Affiliate  or  division  of the  Company)  under  one or more of the
measures described above relative to the performance of other corporations. Such
performance  goals  shall  be  set by  the  Committee  within  the  time  period
prescribed  by, and shall  otherwise  comply with the  requirements  of, Section
162(m) of the Code,  or any successor  provision  thereto,  and the  regulations
thereunder.

    (c)  Notwithstanding  any provision of this Plan other than Section 11, with
respect  to any Award  that is subject to this  Section  12, the  Committee  may
adjust  downwards,  but not upwards,  the amount payable pursuant to such Award,
and the Committee may not waive the  achievement of the  applicable  performance
goals except in the case of the death or disability of the Participant.

    (d) The Committee shall have the power to impose such other  restrictions on
Awards  subject to this Section 12 as it may deem  necessary or  appropriate  to
ensure  that  such  Awards  satisfy  all  requirements  for   "performance-based
compensation"  within the meaning of Section  162(m) (4) (C) of the Code, or any
successor provision thereto.

    (e)  Notwithstanding  any provision of this Plan other than Section 4(d), no
Participant may be granted Options and/or SARs in any three calendar year period
with respect to more than two million (2,000,000) Shares, and the maximum dollar
value payable with respect to  Performance  Units and/or Other Stock Unit Awards
that are valued with  reference to property other than Shares and granted to any
Participant in any one calendar year is $10,000,000.

    SECTION 13. AMENDMENTS AND TERMINATION. The Board may amend, alter, suspend,
discontinue or terminate the Plan or any portion  thereof at any time;  provided
that no such amendment, alteration,  suspension,  discontinuation or termination
shall be made without (i) shareholder  approval if such approval is necessary to



qualify for or comply with any tax or regulatory  requirement  for which or with
which the Board deems it necessary or desirable to qualify or comply or (ii) the
consent of the affected  Participant,  if such action would impair the rights of
such Participant under any outstanding  Award.  Notwithstanding  anything to the
contrary  herein,  the  Committee  may amend  the Plan in such  manner as may be
necessary so as to have the Plan conform to local rules and  regulations  in any
jurisdiction outside the United States.

    The  Committee  may  amend  the  terms  of any  Award  theretofore  granted,
prospectively or retroactively, but no such amendment shall impair the rights of
any  Participant  without his or her consent.  Notwithstanding  any provision of
this  plan,  the  Committee  may not amend the terms of any Option to reduce the
option price.

    SECTION 14.  GENERAL PROVISIONS.

    (a)  Unless  the  Committee  determines  otherwise  at the time the Award is
granted or thereafter:  (i) no Award,  and no Shares subject to Awards described
in  Section  10 which  have  not  been  issued  or as to  which  any  applicable
restriction,  performance  or  deferral  period  has not  lapsed,  may be  sold,
assigned, transferred, pledged or otherwise encumbered, except by will or by the
laws of  descent  and  distribution;  provided  that,  if so  determined  by the
Committee,  a  Participant  may,  in the manner  established  by the  Committee,
designate a beneficiary to exercise the rights of the  Participant  with respect
to any Award upon the death of the  Participant;  and (ii) each  Award  shall be
exercisable,  during the Participant's  lifetime, only by the Participant or, if
permissible  under  applicable  law,  by the  Participant's  guardian  or  legal
representative.

    (b) The term of each Award  shall be for such period of months or years from
the date of its grant as may be determined by the Committee; provided that in no
event shall the term of any  Incentive  Stock  Option or any Stock  Appreciation
Right  related to any  Incentive  Stock Option exceed a period of ten (10) years
from the date of its grant.

    (c) No Employee or Participant  shall have any claim to be granted any Award
under  the Plan and  there is no  obligation  for  uniformity  of  treatment  of
Employees or Participants under the Plan.

    (d) The  prospective  recipient of any Award under the Plan shall not,  with
respect to such Award,  be deemed to have become a  Participant,  or to have any
rights with respect to such Award,  until and unless such  recipient  shall have
executed an agreement or other  instrument  evidencing the Award and delivered a
copy thereof to the Company,  and otherwise  complied  with the then  applicable
terms and conditions.

    (e) Except as provided in Section 12, the  Committee  shall be authorized to
make adjustments in performance award criteria or in the terms and conditions of
other Awards in  recognition  of unusual or  nonrecurring  events  affecting the
Company or its financial  statements or changes in applicable laws,  regulations
or  accounting  principles.  The  Committee  may correct any defect,  supply any
omission or reconcile any  inconsistency  in the Plan or any Award in the manner
and to the extent it shall deem desirable to carry it into effect.  In the event
the Company shall assume  outstanding  employee  benefit  awards or the right or
obligation to make future such awards in connection  with the  acquisition of or
combination with another  corporation or business entity,  the Committee may, in
its discretion,  make such  adjustments in the terms of Awards under the Plan as
it shall deem appropriate.



    (f) The Committee shall have full power and authority to determine  whether,
to what  extent and under what  circumstances  any Award  shall be  canceled  or
suspended.  In addition,  all  outstanding  Awards to any  Participant  shall be
canceled if the Participant,  without the consent of the Company, while employed
by  the  Company  or  after  termination  of  such  employment,   establishes  a
relationship with a competitor of the Company or engages in activity which is in
conflict with or adverse to the interest of the Company, as determined under the
AT&T Non-Competition Guideline.

    (g) All  certificates  for Shares  delivered  under the Plan pursuant to any
Award shall be subject to such  stock-transfer  orders and other restrictions as
the  Committee  may deem  advisable  under  the  rules,  regulations,  and other
requirements of the Securities and Exchange Commission,  any stock exchange upon
which the Shares are then listed, and any applicable Federal or state securities
law,  and the  Committee  may  cause a legend or  legends  to be put on any such
certificates to make appropriate reference to such restrictions.

    (h) No  Award  granted  hereunder  shall  be  construed  as an offer to sell
securities of the Company,  and no such offer shall be  outstanding,  unless and
until the Committee in its sole  discretion has determined  that any such offer,
if made,  would be in compliance  with all applicable  requirements  of the U.S.
federal  securities laws and any other laws to which such offer, if made,  would
be subject.

     (i) The Committee shall be authorized to establish  procedures  pursuant to
which the payment of any Award may be deferred. Subject to the provisions of the
Plan and any Award  Agreement,  the  recipient of an Award  (including,  without
limitation,  any deferred  Award) may, if so  determined  by the  Committee,  be
entitled to receive,  currently or on a deferred basis, cash dividends,  or cash
payments  in  amounts   equivalent  to  cash  dividends  on  Shares   ("dividend
equivalents"),  with  respect to the number of Shares  covered by the Award,  as
determined  by the  Committee,  in its sole  discretion,  and the  Committee may
provide  that such amounts (if any) shall be deemed to have been  reinvested  in
additional Shares or otherwise reinvested.

    (j) Except as otherwise required in any applicable Award Agreement or by the
terms of the Plan,  recipients of Awards under the Plan shall not be required to
make any payment or provide consideration other than the rendering of services.

    (k) The Committee may delegate to one or more Senior Managers or a committee
of Senior  Managers the right to grant Awards to Employees  who are not officers
or directors of the Company and to cancel or suspend Awards to Employees who are
not officers or directors of the Company.

    (l) The Company  shall be  authorized  to withhold from any Award granted or
payment due under the Plan the amount of withholding  taxes due in respect of an
Award or payment  hereunder and to take such other action as may be necessary in
the opinion of the Company to satisfy  all  obligations  for the payment of such
taxes. The Committee shall be authorized to establish procedures for election by
Participants  to  satisfy  such  obligations  for the  payment  of such taxes by
delivery of or transfer of Shares to the Company, or by directing the Company to
retain Shares otherwise deliverable in connection with the Award.

    (m) Nothing  contained  in this Plan shall  prevent the Board from  adopting
other or additional compensation  arrangements,  subject to shareholder approval
if such  approval is required;  and such  arrangements  may be either  generally
applicable or applicable only in specific cases.



    (n) The  validity,  construction,  and  effect of the Plan and any rules and
regulations relating to the Plan shall be determined in accordance with the laws
of the State of New York and applicable Federal law.

    (o) If any  provision  of this  Plan is or  becomes  or is  deemed  invalid,
illegal or  unenforceable in any  jurisdiction,  or would disqualify the Plan or
any Award under any law deemed applicable by the Committee, such provision shall
be construed or deemed amended to conform to applicable  laws or if it cannot be
construed or deemed  amended  without,  in the  determination  of the Committee,
materially  altering  the  intent  of the  Plan,  it shall be  stricken  and the
remainder of the Plan shall remain in full force and effect.

    (p) Awards may be granted to Employees who are foreign nationals or employed
outside the United States, or both, on such terms and conditions  different from
those applicable to Awards to Employees employed in the United States as may, in
the judgment of the  Committee,  be necessary or desirable in order to recognize
differences in local law or tax policy. The Committee also may impose conditions
on the  exercise  or  vesting  of  Awards  in order to  minimize  the  Company's
obligation with respect to tax equalization for Employees on assignments outside
their home country.

    SECTION 15.  EFFECTIVE  DATE OF  PLAN.  The  Plan shall  be effective  as of
June 1, 1997.

    SECTION 16.  TERM OF PLAN.  No Award  shall be granted pursuant to  the Plan
after  May 31, 2002, but any  Award theretofore  granted may extend  beyond that
date.
