ITEM 1. BUSINESS.

GENERAL

         AT&T Corp. ("AT&T" or the "Company") was incorporated in 1885 under the
laws of the  State of New York and has its  principal  executive  offices  at 32
Avenue  of the  Americas,  New  York,  New  York  10013-2412  (telephone  number
212-387-5400). Internet users can access information about AT&T and its services
at http://www.att.com/.

         AT&T   is   currently   a   major   participant   in  two   industries:
telecommunications   and   financial   services.   AT&T  is  among  the  world's
communications  leaders,  providing  voice,  data and  video  telecommunications
services to large and small businesses,  consumers and government entities. AT&T
and  its  subsidiaries  furnish  regional,  domestic,  international  and  local
communication transmission services. AT&T's wholly owned subsidiaries, including
AT&T Wireless  Services,  Inc.,  provide  cellular  telephone and other wireless
services.  AT&T also provides billing,  directory,  and calling card services to
support its communications business as well as offering a general purpose credit
card through its wholly owned  subsidiary,  AT&T  Universal  Card Services Corp.
("AT&T Universal Card Services").

         On  September  20,  1995,  AT&T  announced  a  plan  to  separate  (the
"Separation")  into three publicly held stand-alone  global companies focused on
serving certain core  businesses:  communication  and  information  services and
general  purpose  credit card (to be carried on by the new AT&T,  which includes
AT&T  Universal  Card  Services),  communications  systems and technology (to be
carried on by Lucent Technologies Inc.  ("Lucent")),  and  transaction-intensive
computing  (to be carried on by NCR  Corporation  ("NCR",  formerly  AT&T Global
Information Solutions Company)).

         AT&T  completed  the  Separation  in  1996.  AT&T  distributed  to  its
shareowners all of the shares AT&T owned of Lucent on September 30, 1996 and all
of the shares of NCR on December 31, 1996. These  distributions were tax free to
shareowners,  except to the extent cash was received for fractional  shares. The
Lucent distribution had been preceded by the initial public offering of 17.6% of
Lucent shares.  In addition,  on October 1, 1996, AT&T completed the sale of its
majority  interest in AT&T  Capital  Corporation,  in which AT&T  received  $1.8
billion in cash, recognizing a $162 million after-tax gain.

COMMUNICATION AND INFORMATION SERVICES

         AT&T's  communication and information  services business  addresses the
needs of consumers, large and small businesses, the Federal government and state
and local  governments for voice,  data and video  telecommunications  services.
Business  units  within this group  provide  regular  and custom  long  distance
communications services, data transmission services, 500 services,  toll-free or
800 and 888 services,  900 services,  private line  services,  software  defined
network  services   ("SDN"),   integrated   services  digital  network  ("ISDN")
technology based services, and electronic mail, electronic data interchanges and
enhanced facsimile services.

         AT&T also  provides  special long  distance  services,  including  AT&T
Calling Card  services,  special  calling plans and the  Company's  domestic and
international operator services. AT&T provides communications services

<PAGE>

internationally,   including  transaction  services,  global  networks,  network
management  and value  added  network  services  (i.e.,  services  offered  over
communications   transmission   facilities  that  employ   computer   processing
applications).

         AT&T    provides    interstate    and    intrastate    long    distance
telecommunications   services  throughout  the  continental  United  States  and
provides, or joins in providing with other carriers, telecommunications services
to and from Alaska, Hawaii, Puerto Rico and the Virgin Islands and international
telecommunications  services to and from  virtually all nations and  territories
around the world.

         In  the  continental   United  States,   AT&T  provides  long  distance
telecommunications  services  over  its  own  network.  Virtually  all  switched
services are computer  controlled and digitally switched and interconnected by a
packet  switched   signaling   network.   Transmission   facilities  consist  of
approximately  2 billion  circuit-miles  using  lightwave,  satellite,  wire and
coaxial cable and microwave radio technology.  International  telecommunications
services are provided via multiple  international  transoceanic  submarine cable
(primarily  lightwave)  systems  and  via  international   satellite  and  radio
facilities.

         AT&T has also  begun  providing  a variety of new  services,  including
online services,  internet access and local telecommunications  services. Online
and internet access services include AT&T WorldNet* Service, a service providing
dedicated and dial-up access to the internet, AT&T Easy World Wide Web* Service,
an internet  web site  creation  and hosting  service,  custom web site  hosting
services,  and AT&T SecureBuy*  Service,  an Internet  transaction  service that
simplifies buying and selling on the Internet.

         Following   passage  of  the   Telecommunications   Act  of  1996  (the
"Telecommunications  Act"),  AT&T has applied for  permission  to provide  local
service in all 50 states.  At December 31, 1996, AT&T had received  authority to
provide service in 42 states and anticipates  that it will receive the remaining
approvals   as  the  other   states  take  the  actions   contemplated   by  the
Telecommunications  Act.  In the fourth  quarter of 1996,  AT&T began  providing
local  telephone  service to  residential  customers  on a  controlled  basis in
Sacramento,  California. In addition, in February 1997 AT&T began offering local
telephone  service  to  business  customers  throughout  California  as  well as
offering in 45 states AT&T Digital  Link,  which enables  business  customers to
place local calls over high capacity lines connected directly to AT&T's existing
switches.

         AT&T  Solutions,  Inc.,  established in 1995,  assists  corporations in
global  network and computer  management.  AT&T  Solutions  designs,  builds and
operates corporate clients' computer networks, designs software and manages data
centers for its clients.

AT&T is one of the world's largest  wireless  service  providers.  In the United
States,  AT&T holds licenses to operate  systems  providing  broadband  wireless
services  covering markets with a population of over 200 million  nationwide and
messaging and air-to-ground services throughout the country. The
- ------------
* Service Mark
<PAGE>

services   provided  by  AT&T   currently   include   cellular,   messaging  and
air-to-ground communications.

         In addition, AT&T has purchased (primarily in auctions conducted by the
Federal Communications  Commission ("FCC")) wireless broadband PCS (or "personal
communication  services") licenses covering markets with a population of over 70
million.  AT&T is required by the FCC to provide adequate  broadband PCS service
to at least  one-third of the population in its licensed areas within five years
of being  licensed and two-thirds of the population in its licensed areas within
ten years of being  licensed.  The  licenses are granted for ten year terms from
the  original  date of issuance  and may be renewed by AT&T by meeting the FCC's
renewal criteria and upon compliance with the FCC's renewal procedures.

         AT&T has  created  service  clusters  in major  metropolitan  areas and
linked its and other service  providers systems into a network which permits its
wireless  cellular  subscribers  to both place and receive  calls  anywhere they
travel in areas  served by the  network,  even if the local  wireless  telephone
service is not provided by AT&T.  AT&T is now integrating  other  communications
technologies,  such as PCS, into the network.  AT&T will continue to explore the
use of emerging  technologies  to expand the reach of the network and to provide
additional services (especially data and internet services).

         AT&T also offers one-way messaging systems such as paging services.  As
of  December  31,  1996,  the Company  had over 1.1  million  messaging  service
subscribers. The majority of these subscribers are in locations where AT&T holds
cellular or PCS licenses.

         AT&T's wireless services are conducted  primarily through  subsidiaries
of AT&T Wireless Services,  Inc. (formerly McCaw Cellular  Communications,  Inc.
("McCaw")),  which  was  merged  with a  special-purpose  subsidiary  of AT&T in
September 1994. At that time,  McCaw owned 52% of LIN  Broadcasting  Corporation
(which held cellular and broadcast television  properties),  which in turn owned
100%  of  LIN  Television  Corporation.   In  December  1994,  LIN  Broadcasting
Corporation  distributed to its  shareholders all of the stock of LIN Television
Corporation, so that upon the distribution AT&T became the direct owner (through
its  wholly  owned  subsidiaries)  of  52%  of LIN  Television  Corporation.  In
September  1995, AT&T acquired the remaining 48%  publicly-held  interest in LIN
Broadcasting Corporation at an aggregate price of approximately $3.3 billion.

         AT&T has  established a number of  international  alliances to increase
the reach and scope of AT&T's  network  over time and has  invested  in  certain
countries  in order to  increase  the  range of  services  AT&T  offers in those
countries.  For  example,  AT&T  founded the  WorldPartners  alliance in 1993 to
provide  multinational  customers with seamless  telecommunications  and related
services. As of the end of 1996,  WorldPartners  included 30 members who provide
services  to  multinational  customers  in North  America,  Europe and Asia.  In
addition,  in 1996 AT&T began  offering  business and  consumer  services in the
United Kingdom and in early 1997 AT&T's joint venture in Mexico,  Alestra, began
offering long distance  service.  AT&T also has an interest in several  wireless
communications  companies  outside  of the  United  States,  including  cellular
operators licensed to serve Hong Kong, Columbia and parts of India.

AT&T UNIVERSAL CARD SERVICES

         AT&T Universal  Card Services began  operations in early 1990. The AT&T
Universal  Card is a  combined  general-purpose  consumer  credit  card and AT&T
Calling Card that at year-end had managed receivables in excess of $13.5 billion
in 1996, $14.1 billion in 1995, $12.3 billion in 1994, $9.1 billion in 1993, and
$6.6 billion in 1992. The AT&T Universal Card is offered  directly  through AT&T
Universal  Financial Corp., a Utah industrial loan company,  and Universal Bank,
N.A., in Columbus,  Georgia,  which are both wholly owned by AT&T,  and under an
affinity relationship with Columbus Bank and Trust Company in Columbus, Georgia,
a subsidiary of Synovus  Financial Corp.  AT&T Universal Card Services  provides
marketing  and  customer  support  for the AT&T  Universal  Card  program and it
purchases cardholder receivables generated by the AT&T Universal Card program.

         Some  seasonality  exists in the consumer credit card industry,  with a
higher number of purchases  occurring during the year-end holiday season.  Based
on the number of cardholder accounts,  the AT&T Universal Card program is one of
the largest bankcard/credit card programs in the United States.

LEGISLATIVE AND REGULATORY DEVELOPMENTS

Telecommunications Act of 1996

         In  February   1996,  the   Telecommunications   Act  became  law.  The
Telecommunications  Act,  among  other  things,  was  designed  to foster  local
exchange  competition  by  establishing  a  regulatory  framework  to govern new
competitive  entry in local and long  distance  telecommunications  services and
requiring  incumbent local exchange  carriers  ("LECs"),  including the Regional
Bell Operating Companies ("RBOCs"),  to implement a checklist of conditions that
would support local exchange  competition.  These conditions  include  requiring
incumbent  LECs to provide to competing  service  providers  (i) local  exchange
services  for resale at  wholesale  rates,  (ii)  interconnection  and access to
unbundled  network elements at any technically  feasible point and at cost-based
rates, (iii) telephone number portability for customers changing carriers,  (iv)
dialing parity for customers and (v) access to rights of way.

         The  Telecommunications Act also permits an RBOC to petition the FCC at
any time for  permission to provide  interexchange  services  originating in any
state in its region. The FCC must review such request within 90 days, but cannot
approve  such a request  unless  (i)  approval  is  consistent  with the  public
interest,  convenience  and  necessity;  (ii)  the FCC has  consulted  with  the
Department  of Justice  ("DOJ")  and given the DOJ's views  substantial  weight;
(iii)  the  RBOC  has  implemented  the   Telecommunications  Act  checklist  of
conditions  throughout such state; and (iv) either (A) the RBOC has entered into
a binding interconnection agreement, approved by the relevant state, with one or
more  unaffiliated  competing  providers of telephone service to residential and
business  subscribers which are offered either exclusively or predominantly over
such competitors' own facilities,  or (B) the RBOC has received no such requests
for interconnection within the statutory prescribed time period.

In August 1996, the FCC adopted rules and regulations (the "Implementing Rules")
to implement the local  competition  provisions of the  Telecommunications  Act,
including with respect to the terms and conditions of  interconnection  with LEC
networks and the standards  governing the purchase of unbundled network elements
and wholesale services from LECs. The Implementing
<PAGE>

Rules rely on each state to develop the specific  rates and  procedures  in such
state within the framework  prescribed by the FCC for developing  such rates and
procedures.

         For  example,   the  Implementing  Rules  identify  a  minimum  set  of
technically  feasible  points  of  interconnection  that an  incumbent  LEC must
provide;  identify a minimum set of network elements that must be made available
by an incumbent  LEC on an unbundled  basis,  without  restriction;  and require
incumbent LECs to provide nondiscriminatory access to operations support systems
for ordering, provisioning, maintenance and repair.

         In addition, the Implementing Rules establish a methodology that states
must use for determining the wholesale rates that LECs must provide to resellers
of their  services and which is based on retail rates less  marketing,  billing,
collection and other avoided or avoidable  costs. In addition,  the Implementing
Rules  establish  a default  discount in the range of 17-25% that states may use
pending implementation of this methodology.

         Finally,  the  Implementing  Rules  require  states to set  prices  for
interconnection  and unbundled  network  elements  pursuant to a forward looking
economic cost pricing  methodology  which is based on the Total Element Long-Run
Incremental  Cost  ("TELRIC") of providing a particular  network  element plus a
reasonable share of forward-looking joint and common costs. If states are unable
to conduct a cost study to determine  such rates within the statutory time frame
for  arbitrating  interconnection  disputes,  the  Implementing  Rules establish
default ranges or ceilings for unbundled network elements.

Although the FCC deferred interstate access charge reform to another proceeding,
the Implementing  Rules only permit incumbent LECs to recover from interexchange
carriers using unbundled  network elements for local service certain portions of
the current interstate access charges.  Such interexchange  carriers will not be
required  to pay  these  charges  as of the  earliest  of  July  1,  1997 or the
occurrence of certain other events, such as RBOC receipt of authority to provide
in-region long distance service.

         In October 1996, the United States Court of Appeals for the 8th Circuit
ordered a stay of the  effectiveness  of those  provisions  of the  Implementing
Rules  addressed to the pricing of  unbundled  network  elements  and  wholesale
services  ("Pricing  Rules"),  among  others,  until  such  court  resolves  the
challenges to the Implementing Rules by local telephone  companies and telephone
regulators  in several  states.  The court heard  argument on the  challenges in
January 1997.

         AT&T  believes  that the stay of the  Pricing  Rules  may  inhibit  the
establishment  of  appropriate  permanent  rates for the  provision  of  network
elements and wholesale  services.  Absent full effectiveness of the Implementing
Rules, each state will determine the applicable rates and procedures independent
of the framework of the Pricing  Rules.  Since the stay was issued,  many states
have used the Pricing  Rules as guidelines  in  establishing  interim rates that
will apply pending the  determination  of permanent  rates in  subsequent  state
proceedings.  Nevertheless, in the absence of the Pricing Rules, there can be no
assurance  that the prices and other  conditions  established in each state will
provide for effective  local service entry and  competition or provide AT&T with
new market opportunities.

         AT&T has  applied for  permission  to provide  local  service in all 50
states. At December 31, 1996, AT&T had received  authority to provide service in
42 states and  anticipates  that it will receive the remaining  approvals as the
other states take the actions contemplated by the Telecommunications  Act. While
the Telecommunications Act makes clear that no state can prohibit AT&T or any

<PAGE>

other entity from providing local services, AT&T cannot be certain as to when it
will receive certification in each state and the conditions that might attach to
each such  certification.  Most of the RBOCs have indicated  their  intention to
petition the FCC during 1997 for permission to provide interexchange services in
one or more states within their home market.

         As a result of the  legislative and regulatory  developments  discussed
above, there can be no assurance that all of the necessary preconditions for the
development of effective local  competition will be achieved in a timely or even
manner  and  that  long  distance  carriers  will be in a  position  to  compete
effectively  against RBOCs in local service at the time RBOCs receive permission
to enter  the long  distance  market.  Because  it is  widely  anticipated  that
substantial  numbers of long  distance  customers  will seek to purchase  local,
interexchange  and other services from a single carrier as part of a combined or
full service  package,  any  competitive  disadvantage,  inability to profitably
provide local service at competitive rates or delays or limitations in providing
local service or combined  service packages could adversely affect AT&T's future
revenues and earnings.

Modification of Final Judgment of 1982

         Prior to 1996, AT&T and the RBOCs were subject to the provisions of the
Modification of Final Judgment of 1982 (the "MFJ") since its implementation. The
Telecommunications Act effectively superseded future
operation  of the MFJ.
Consequently, on April 11, 1996, Judge Harold Greene issued an order terminating
the MFJ.

Regulation of Rates

         AT&T  is  subject  to the  jurisdiction  of the  FCC  with  respect  to
interstate and international rates, lines and services,  and other matters. From
July 1989 to October 1995, the FCC regulated AT&T under a system known as "price
caps" whereby AT&T's prices, rather than its earnings,  were limited. On October
12, 1995,  recognizing a decade of enormous  change in the long distance  market
and finding  that AT&T  lacked  market  power in the  interstate  long  distance
market,  the FCC reclassified AT&T as a "non-dominant"  carrier for its domestic
interstate services. As a result, AT&T became subject to the same regulations as
its long  distance  competitors  for such  services.  Thus,  AT&T was no  longer
subject to price cap  regulation  for these  services,  was able to file tariffs
that are presumed lawful on one day's notice,  and was free of other regulations
and reporting requirements that apply only to dominant carriers.

         In addition,  in further  recognition of competitive  developments,  on
October  31,  1996,  the FCC  issued an order,  to be  effective  in late  1997,
prohibiting AT&T and other  non-dominant  carriers from filing tariffs for their
domestic  interstate  services.  Accordingly,  carriers  will be required to use
contracts and other  commercial  arrangements  to establish the terms of service
with  customers.  In February  1997,  the United States Court of Appeals for the
District of Columbia  ordered a stay of the  effectiveness  of the FCC'c  order.
Argument is expected to be heard later this year.

         AT&T remains  subject to the statutory  requirements of Title II of the
Communications  Act. AT&T must offer service under rates,  terms and  conditions
that are just, reasonable and not unreasonably discriminatory,  it is subject to
the FCC's  complaint  process,  and it must give notice to the FCC and  affected
customers prior to discontinuance, reduction, or impairment of service. AT&T has
also made certain commitments that address concerns that had been raised with

<PAGE>

regard to the potential impact of declaring AT&T to be non-dominant, including a
three-year rate assurance for low income and low usage  residential  users and a
three-year  limit on, and 5 days  advance  notice  for,  rate  increases  on 800
directory assistance and analog private line services.

         AT&T's  international  private line  services  have been  classified as
non-dominant  for several years.  AT&T's  switched  international  services have
become subject to increased competition, similar to its domestic services and on
May 9, 1996,  the FCC  adopted  an order  reclassifying  AT&T as a  non-dominant
carrier for such  services.  AT&T has made certain  voluntary  commitments  that
address issues raised in that proceeding, including commitments: (i) to maintain
its annual average revenue per minute for international  residential calls at or
below the 1995  level  through  May 9, 1999,  and in the event of a  significant
change that substantially  raises AT&T's costs, to provide the FCC five business
days notice prior to  implementing  rate  increases  that would raise the annual
average  revenue  per minute for such calls  above the 1995  level;  and (ii) to
maintain  certain  discount  calling plans providing at least a 15% discount off
basic pricing schedules until May 9, 1999. AT&T also made voluntary  commitments
relating to its operation of international cable facilities,  its negotiation of
settlement  agreements with foreign carriers and its  relationship  with foreign
partners.

         In  addition  to  the  matters  described  above  with  respect  to the
Telecommunications  Act, state public service commissions or similar authorities
having  regulatory  power over  intrastate  rates,  lines and services and other
matters regulate AT&T's local and intrastate communications services. The system
of regulation used in many states is rate-of-return regulation. In recent years,
many states have adopted  different  systems of  regulation,  such as:  complete
removal of rate-of-return regulation, pricing flexibility rules, price caps, and
incentive regulation.

COMPETITION

     AT&T  currently  faces  significant  competition in the  communication  and
information  services  industry and expects that the level of  competition  will
continue to increase.  As  competitive,  regulatory  and  technological  changes
occur,  including  those  occasioned by the enactment of the  Telecommunications
Act, AT&T anticipates  that new and different  competitors will enter and expand
their  position  in the  communications  services  markets.  These  may  include
entrants  from other  segments of the  communication  and  information  services
industry or global  competitors  seeking to expand their  market  opportunities.
Many such new  competitors  are likely to enter with a strong  market  presence,
well recognized names and pre-existing direct customer relationships.

         The   Telecommunications   Act  has  already  begun  to  intensify  the
competitive  environment.  Anticipating changes in the industry,  non-RBOC LECs,
which are not required to implement  the  Telecommunications  Act's  competitive
checklist  prior to offering  long  distance in their home  markets,  have begun
integrating  their local  service  offerings  with long  distance  offerings  in
advance of AT&T being able to offer combined local and long distance  service in
these areas. If such non-RBOC LECs continue to offer combined  services  without
offering reasonable terms of interconnection and service elements at competitive
rates,  AT&T's  revenues and earnings in these service regions will be adversely
affected.

         Similarly,  to the extent  that the RBOCs  obtain  in-region  interLATA
authority before the Telecommunications Act's checklist of conditions have been

<PAGE>

fully or satisfactorily implemented and adequate facilities-based local exchange
competition   exists,   there  is  a  substantial   risk  that  AT&T  and  other
interexchange  service  providers  would be at a  disadvantage  to the  RBOCs in
providing both local service and combined  service  packages.  Furthermore,  the
previously   announced  merger  of  British   Telecommunications   PLC  and  MCI
Communications Corp. will create a large, well-capitalized competitor for AT&T's
offerings, domestically as well as internationally,  with substantial financial,
technical, marketing and other resources and a large worldwide installed base of
customers.

        Furthermore,  in February 1997, a General Agreement on Trade in Services
(the "GATS") was reached  under the World Trade  Organization.  The GATS,  which
will  become  effective  January 1, 1998,  is  designed  to open each  country's
domestic telecommunications markets to foreign competitors. The GATS, and future
trade  agreements,  may accelerate the entrance into the U.S.  market of foreign
telecommunications  providers,  certain of whom are  likely to possess  dominant
home market positions in which there is not effective competition.  The GATS may
also  permit  AT&T's  entrance  into  other  markets  as only a small  number of
countries refused to eliminate their foreign ownership restrictions.

         In addition to the matters  referred to above,  various other  factors,
including  market  acceptance,  start-up and ongoing costs  associated  with the
provision of new services and local  conditions and obstacles,  could  adversely
affect  the  timing  and  success  of AT&T's  entrance  into the local  exchange
services  market and AT&T's  ability to offer  combined  service  packages  that
include local service.  In addition,  the simultaneous  entrance of numerous new
competitors  for  interexchange  and  combined  service  packages  is  likely to
adversely  affect  AT&T's long  distance  revenues  and could  adversely  affect
earnings.

        AT&T's other industry segment, the financial services industry,  is also
highly   competitive.   Participants  in  the  industry  compete  through  price
(including  the  ability to control  costs),  risk  management,  innovation  and
customer service.  Principal cost factors include the cost of funds, the cost of
selling to or acquiring  new  end-user  customers  and vendors,  and the cost of
managing portfolios (including,  for example, billing,  collection,  credit risk
management and residual management).


FORWARD LOOKING STATEMENTS

         Except for the historical  statements and discussions contained herein,
statements  contained in this Report on Form 10-K  constitute  "forward  looking
statements"  within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Any Form 10-K, Annual Report
to  Shareowners,  Form  10-Q or Form 8-K of AT&T  may  include  forward  looking
statements.  In addition,  other  written or oral  statements  which  constitute
forward looking statements have been made and may in the future be made by or on
behalf of AT&T,  including statements  concerning future operating  performance,
AT&T's share of new and existing  markets,  AT&T's short- and long-term  revenue
and  earnings  growth  rates,  and  general  industry  growth  rates and  AT&T's
performance relative thereto.  These forward looking statements rely on a number
of   assumptions   concerning   future   events,   including  the  adoption  and
implementation  of balanced and effective  rules and  regulations by the FCC and
the  state  public  regulatory  agencies,   and  AT&T's  ability  to  achieve  a
significant market penetration in new markets.  These forward looking statements
are subject to a number of uncertainties and other factors, many of which are

<PAGE>

outside AT&T's  control,  that could cause actual  results to differ  materially
from such statements. These factors include, but are not limited to:

- - the efficacy of the Implementing Rules and other rules and regulations to be
  adopted by the FCC to implement the provisions of the Telecommunications Act;

- - the outcome of negotiations  with LECs and state  regulatory arbitrations and
  approvals with respect to interconnection agreements; the timing of receipt of
  and the conditions that attach to,  certification  to provide local service in
  each  state;  and the  ability  to  purchase  unbundled network  elements  or
  wholesale  services from LECs at a price  sufficient to permit the  profitable
  offering of local exchange service at competitive rates;

- - success and market  acceptance  for new  offerings,  including local service;
  start-up costs associated with entering new markets, including advertising and
  promotional efforts;  successful deployment of new systems and applications to
  support new offerings; and local conditions and obstacles;

- - competitive pressures, including pricing pressures, technological developments
  and the ability to offer combined service packages that include local service;
  the extent and pace at which different  competitive environments  develop for
  each segment of the  telecommunications  industry; the extent at and duration
  for which competitors from each segment of the telecommunications industry are
  able to offer  combined or full service  packages prior to AT&T being able to;
  and the degree to which AT&T experiences  material  competitive impacts to its
  traditional service offerings prior to achieving adequate local service entry;

- - the availability, terms and deployment of capital; and the ability to achieve
  cost savings; and

- - general economic conditions,  government and regulatory policies, and business
  conditions in the communications industry.

         Readers are cautioned not to put undue reliance on such forward looking
statements.   For  a  more  detailed   description   of  these  and   additional
uncertainties  and other  factors  that  could  cause  actual  results to differ
materially  from such forward looking  statements,  see "Results of Operations",
"Financial   Condition",   "Regulatory   and  Legislative   Developments",   and
"Competition"  included in or  incorporated by reference into this Form 10-K. As
described  elsewhere in this Form 10-K,  these  uncertainties  and factors could
adversely  affect  the  timing and  success  of AT&T's  entrance  into the local
exchange  services market and AT&T's ability to offer combined  service packages
that include local service,  thereby adversely  affecting AT&T's future revenues
and earnings. AT&T disclaims any intention or obligation to update or revise any

<PAGE>

Statements  of  Income on page 30 of the  Company's  annual  report to  security
holders  for  the  year  ended  December  31,  1996.  All  such  information  is
incorporated herein by reference pursuant to General Instruction G(2).

EMPLOYEE RELATIONS

         At December 31, 1996 AT&T employed approximately 130,000 persons in its
operations, approximately 124,000 of whom are located domestically. About 41% of
the domestically  located  employees of AT&T are represented by unions. Of those
so  represented,  about 96% are  represented  by the  Communications  Workers of
America  ("CWA"),  which  is  affiliated  with  the  AFL-CIO;  about  4% by  the
International   Brotherhood  of  Electrical  Workers  ("IBEW"),  which  is  also
affiliated  with the AFL-CIO.  In addition,  there is a very small  remainder of
domestic  employees  represented by other unions.  Labor agreements with most of
these unions extend through May 1998.

ITEM 2.  PROPERTIES.

         The properties of AT&T consist primarily of plant and equipment used to
provide long  distance  telecommunications  services and  administrative  office
buildings.

         Telecommunications  plant and  equipment  consists of:  central  office
equipment,  including  switching and  transmission  equipment;  connecting lines
(cables,  wires, poles, conduits,  etc.); land and buildings;  and miscellaneous
properties  (work equipment,  furniture,  plant under  construction,  etc.). The
majority of the  connecting  lines are on or under  public  roads,  highways and
streets and international and territorial  waters. The remainder are on or under
private  property.  AT&T also operates a number of sales offices,  customer care
centers, and other facilities, such as research and development laboratories.

         AT&T continues to manage the  deployment and  utilization of its assets
in order to meet its global  growth  objectives  while at the same time ensuring
that these assets are generating economic value added for the shareholder.  AT&T
will  continue  to  manage  its  asset  base   consistent   with   globalization
initiatives, marketplace forces, productivity growth and technology change.

         A  substantial  number  of the  administrative  offices  of AT&T are in
leased buildings.  Substantially all of the important communications  facilities
are in  buildings  owned by AT&T or leased from the regional  holding  companies
created at divestiture.  Many of the smaller  facilities are in rented quarters.
Most of the  important  buildings are on land held in fee, but a few are on land
held under long-term leases.

ITEM 3.  LEGAL PROCEEDINGS.

         In the normal  course of  business,  AT&T is  subject  to  proceedings,
lawsuits and other  claims,  including  proceedings  under  government  laws and
regulations related to environmental and other matters. Such matters are subject
to  many   uncertainties  and  outcomes  are  not  predictable  with  assurance.
Consequently,  AT&T is unable to  ascertain  the  ultimate  aggregate  amount of
monetary liability or financial impact with respect to these matters at December
31, 1996. While these matters could affect operating  results of any one quarter
when resolved in future periods, it is management's opinion that after final

<PAGE>

disposition,  any monetary  liability  or  financial  impact to AT&T beyond that
provided  for at year-end  would not be material to AT&T's  annual  consolidated
financial position or results of operations.

     On February 14, 1996,  Bell  Atlantic  Corporation  and DSC  Communications
Corporation  filed a  complaint  against  AT&T and Lucent in the  United  States
District Court for the Eastern District of Texas. The complaint asserted,  among
other  things,  monopolization  or attempted  monopolization  claims  concerning
communications    transmission   equipment,    related   software   and   caller
identification  services.  AT&T filed  counterclaims  against Bell  Atlantic and
Lucent filed counterclaims  against DSC Communications.  In the first quarter of
1997, Bell Atlantic,  DSC Communications,  AT&T and Lucent independently reached
separate settlements with plaintiffs pursuant to confidential agreements,  which
resolved  the claims among the parties.  The  settlements  will have no material
impact on AT&T's financial position or results of operations.

         AT&T is also a named party in a number of environmental  actions,  none
of which are material to the  consolidated  financial  statements or business of
the Company. In addition,  pursuant to the Separation and Distribution Agreement
by and among AT&T, Lucent, and NCR, dated as of February 1, 1996 and amended and
restated  as of March 29,  1996,  Lucent has assumed  liability,  subject to the
liability sharing provisions of that agreement, for a number of actions in which
AT&T remains a named  party.  AT&T is working to be released as a party to these
actions,  although  there can be no assurance that it will be successful in this
regard.

     There are three environmental proceedings which are required to be reported
pursuant to  Instruction  5.C. of Item 103 of  Regulation  S-K, all of which are
proceedings for which Lucent has assumed liability,  as described above. On July
31, 1991, the United States Environmental  Protection Agency Region III issued a
complaint  pursuant to Section 3008a of the Resource  Conservation  and Recovery
Act alleging violations of various waste management regulations at the Company's
Richmond Works, Richmond,  Virginia. The complaint seeks a total of $4.2 million
in penalties.  In addition,  on July 31, 1991,  the United States  Environmental
Protection  Agency filed a civil  complaint in the U.S.  District  Court for the
Southern District of Illinois against the Company and nine other parties seeking
enforcement  of  its  Comprehensive  Environmental  Response,  Compensation  and
Liability Act ("CERCLA") Section 106 cleanup order,  issued in November 1990 for
the NL Granite  City  Superfund  site,  Granite,  Illinois,  past  costs,  civil
penalties  of $25,000  per day and  treble  damages  related  to certain  United
States' costs. Finally,  during 1994, AT&T Nassau Metals Corporation ("Nassau"),
a  wholly  owned  subsidiary  of  AT&T,  and the New York  State  Department  of
Environmental  Conservation ("NYSDEC") were engaged in negotiations over a study
and  cleanup  of the Nassau  plant  located on  Richmond  Valley  Road in Staten
Island,  New York.  During these  negotiations,  in June 1994,  NYSDEC presented
Nassau with a draft consent order which included not only provisions relating to
site  investigation  and  remediation but also a provision for payment of a $3.5
million   penalty  for  alleged   violations  of  hazardous   waste   management
regulations. No formal proceeding has been commenced by NYSDEC.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS.

   No matter was submitted to a vote of security  holders in the fourth  quarter
of the fiscal year covered by this report.

   All of the above executive officers have held high level managerial positions
with AT&T or its  affiliates  for more than the past five years,  except Messrs.
Hooper,  Millar,  Miller, Nagel, Ponder,  Srednicki and Walter. Prior to joining
AT&T  in  September   1994,  at  the  time  of  the  merger  of  McCaw  Cellular
Communications,  Inc. with AT&T, Mr. Hooper was Chief Financial Officer of McCaw
(AT&T Wireless Services, Inc.), from 1993, and held various other positions with
McCaw prior to that time. Prior to joining AT&T in February 1995, Mr. Millar was
with Unisys Corporation,  an information services company,  serving as President
from 1992. Prior to joining AT&T in August 1993, Mr. Miller was with Wang

<PAGE>

Laboratories,  Inc.,  a computer  company,  from 1989 through  1993,  serving as
President and Chief Operating Officer and later as Chairman, President and Chief
Executive  Officer.  On February 3, 1997,  AT&T  announced  that Mr.  Miller was
resigning his position with AT&T. Prior to joining AT&T in April 1996, Mr. Nagel
was with Apple Computer,  a computer  company,  serving as Senior Vice President
from 1995 and General  Manager from 1988 through 1995.  Prior to joining AT&T in

be  mailed  not less than ten nor more  than  fifty  days  before  the  meeting,
directed to each shareholder  entitled to vote at said meeting at his address as

other address, in which case it shall be directed to him at such other address.

      Section 2. The Board of  Directors  may fix, in  advance,  a date not more
than  fifty  nor less  than  ten days  before  the  date of any  meeting  of the
shareholders as the record date for  determination  of shareholders  entitled to
notice of or to vote at such meeting,  and only  shareholders  of record on such
date shall be entitled to notice of or to vote at such meeting.

      Section 3. Special  meetings of the shareholders may be called at any time

      A notice of not less than ten nor more than  fifty  days shall be given by
mail for each special  meeting,  in the manner provided for notice of the annual
meeting.  Such notice  shall state the purpose or purposes for which the meeting

indicate that the notice is being issued by or at the direction of the person or
persons calling the meeting.

      Section 4. Failure to receive  notice of any meeting shall not  invalidate

      Section  5.  Notice  of  shareholders   business  at  annual  meetings  of

of this By-Law,
           the  shareholder  must have given timely notice thereof
in writing to
           the Secretary of the company and such  business  must

           proper matter for shareholder  action.  To be timely, a
shareholder's
           notice shall be delivered to the Secretary at the
principal executive
           offices of the  company  not later than the close of

           meeting  but not later than the close of business on
the later of the
           90th  calendar day prior to such annual  meeting or the
10th calendar
           day  following the calendar day on which public
announcement  of the
           date of such meeting is first made by the Company.  In
no event shall
           the  public  announcement  of an  adjournment  of an
annual  meeting
           commence a new time period for the giving of a
shareholder's  notice
           as described above. Such shareholder's  notice shall
set forth (a) as
           to any  description of the business  desired to be
brought before the
           meeting,  the reasons for conducting such business at

shareholder  and
           beneficial  owner,  if any, on whose behalf the
proposal is made; and
           (b) as to the shareholder giving the notice and the
beneficial owner,

is made (i) the
           name and address of such shareholder, as they appear on
the Company's
           books,  and of such beneficial owner and (ii) the class
and number of
           shares of the Company which are owned  beneficially
and of record by
           such shareholder and such beneficial owner.


                                   ARTICLE II.

                      The Conduct of Shareholders' Meetings

      At all  meetings of the  shareholders,  the holders of forty per centum of
the  shares  entitled  to vote  thereat  shall  constitute  a quorum,  except as
otherwise required by law; but the shareholders  present may adjourn the meeting
to another  time or place  despite  the absence of a quorum.  Every  shareholder
entitled to vote shall be  entitled  to one vote for each share  standing in his
name on the record of shareholders;  and every shareholder  entitled to vote may
vote in person or by proxy.

      All elections by shareholders shall be by ballot.

      The Board of Directors,  in advance of any  shareholders'  meeting,  shall
appoint three  Inspectors to act at the meeting or any adjournment  thereof.  In
case any person  appointed  fails to appear or act, the vacancy may be filled by
appointment made by the Board in advance of the meeting or at the meeting by the
person presiding thereat.


                                   ARTICLE IV.

         Environmental Liabilities accrued as of the date hereof
solely relating
         to,  arising out of or resulting  from the  existence of
any  leasehold
         interest that is an Lucent Asset if the applicable
lessor, sublessor or
         sub-sublessor under the applicable lease, sublease or
sub-sublease is a
         member of the AT&T Services Group or the NCR Group.

                  2.4.  TERMINATION  OF  AGREEMENTS.  (a) Except as set forth in
Section 2.4(b),  in furtherance of the releases and other  provisions of Section
5.1 hereof,  Lucent and each member of the Lucent  Group,  on the one hand,  and
each of AT&T, NCR and the respective  members of the AT&T Services Group and the
NCR  Group,  on the  other  hand,  hereby  terminate,  any and  all  agreements,
arrangements,  commitments or understandings, whether or not in writing, between
or among Lucent and/or any member of the Lucent Group, on the one hand, and AT&T
or NCR  and/or any member of the AT&T  Services  Group or the NCR Group,  on the
other hand, effective as of the Closing Date;  provided,  however, to the extent
any such agreement,  arrangement,  commitment or  understanding  is inconsistent
with any Ancillary Agreement, such termination shall be effective as of the date
of  effectiveness  of the applicable  Ancillary  Agreement.  No such  terminated
agreement,  arrangement,  commitment or  understanding  (including any provision
thereof which purports


<PAGE>

to  survive  termination)  shall be of any  further  force or  effect  after the
Closing Date (or, to the extent  contemplated  by the proviso to the immediately
preceding  sentence,  after  the  effective  date  of the  applicable  Ancillary
Agreement).  Each party  shall,  at the  reasonable  request of any other party,
take, or cause to be taken, such other actions as may be necessary to effect the
foregoing.


                  (b) The provisions of Section 2.4(a) shall not apply to any of
the following agreements, arrangements, commitments or understandings (or to any
of the provisions thereof): (i) this Agreement and the Ancillary Agreements (and
each other agreement or instrument  expressly  contemplated by this Agreement or
any Ancillary  Agreement to be entered into by any of the parties  hereto or any
of the members of their respective Groups);  (ii) any agreements,  arrangements,
commitments or understandings listed or described on Schedule 2.4(b)(ii);  (iii)
any agreements, arrangements,  commitments or understandings to which any Person
other than the parties  hereto and their  respective  Affiliates  is a party (it
being  understood  that to the extent  that the rights  and  obligations  of the
parties and the members of their  respective  Groups under any such  agreements,
arrangements,  commitments or understandings  constitute Lucent Assets or Lucent
Liabilities,  they  shall  be  assigned  pursuant  to  Section  2.1);  (iv)  any
intercompany  accounts payable or accounts  receivable accrued as of the Closing
Date that are  reflected  in the books and records of the  parties or  otherwise
documented in writing in accordance  with past  practices;  (v) any  agreements,
arrangements, commitments or understandings to which AT&T Capital Corporation or
any other non-wholly  owned  Subsidiary of AT&T,  Lucent or NCR, as the case may
be, is a party (it being understood that directors' qualifying shares or similar
interests will be disregarded  for purposes of determining  whether a Subsidiary
is wholly owned);  (vi) any written Tax sharing or Tax allocation  agreements to
which  any  member of any  Group is a party;  and  (vii)  any other  agreements,
arrangements, commitments or understandings that this Agreement or any Ancillary
Agreement expressly contemplates will survive the Closing Date.


                  2.5. DOCUMENTS RELATING TO TRANSFER OF REAL PROPERTY INTERESTS
AND TANGIBLE  PROPERTY  LOCATED  THEREON.  (a) In furtherance of the assignment,
transfer  and   conveyance  of  Lucent  Assets  and  the  assumption  of  Lucent
Liabilities  set  forth  in  Section  2.1(a)  and (b),  simultaneously  with the
execution and delivery hereof or as promptly as practicable thereafter,  each of
AT&T,  Lucent  and NCR,  or their  applicable  Subsidiaries,  is  executing  and
delivering or will execute and deliver deeds, lease assignments and assumptions,
leases,  subleases  and  sub-subleases  substantially  in the forms  attached as
Schedule 2.5 (which in certain cases includes  different forms for real property
and leasehold interests located outside of the United States), with such changes
as may be necessary to conform to any laws,  regulations or usage  applicable in
the jurisdiction in which the relevant real property is located.
Set forth in,
or  referenced  by, such  Schedule  is,  among other  things,  a summary of each
property or interest  therein to be  conveyed,  assigned,  leased,  subleased or
sub-subleased,  the  applicable  entities  relevant to each  property  and their
capacities  with respect to each  property  (e.g.,  as  transferor,  transferee,
assignor,  assignee,  lessor,  lessee,  sublessor,  sublessee,  sub-sublessor or
sub-sublessee), and any terms applicable to each property that are not specified
in the forms of deed,  lease  assignment  and  assumption,  lease,  sublease  or
sub-sublease (e.g., rent and term).

                  (b) Except as otherwise  expressly  provided in this Agreement
or any Ancillary Agreement, all tenant improvements, fixtures, furniture, office
equipment,  servers,  private  branch  exchanges,  artwork  and  other  tangible
property (other than equipment subject to capital or operating equipment leases,
which will be transferred or retained based on whether the associated capital or
operating equipment lease is or is not an Lucent Contract)


<PAGE>

located  as of the date  hereof  on any real  property  that is  covered  by any
Ancillary  Agreement  referred to in Section  2.5(a),  including  the  Schedules
thereto,  shall, except to the extent expressly set forth on a Schedule referred
to in Section 2.5(a), be transferred or retained as follows:

                  (i) DEEDS AND ASSIGNMENTS. In the case of any
real property or
         leasehold  interests  covered by an  Ancillary
Agreement  set forth on
         Schedule 2.5 that is a deed or lease  assignment  and
assumption,  all
         such  tangible  property  will  be  transferred  to the
transferee  or
         assignee of the applicable real property or leasehold
interest;

                  (ii) SHARED FACILITIES WITHOUT THIRD PARTY
LEASES. In the case
         of any real  property or  leasehold  interests  covered
by an Ancillary
         Agreement set forth on Schedule 2.5 that is a lease,  all
such tangible
         property  will be retained by the lessor  under the
applicable  lease,
         except that any such tangible property (other than tenant
improvements,
         fixtures,  furniture and artwork) used  exclusively by
the lessee shall
         be transferred to, or retained by, the lessee.

                  (iii) SHARED DOMESTIC  FACILITIES WITH THIRD
PARTY LEASES.  In
         the case of any real  property or  leasehold  interests
located in the
         United States  covered by an Ancillary  Agreement set
forth on Schedule
         2.5 that is a sublease or sub-sublease, all such tangible
property will
         be retained by the sublessor or sub-sublessor,
respectively, under the
         applicable  sublease or  sub-sublease,  except  that any
such  tangible
         property  (other  than  tenant  improvements,  fixtures
and  artwork),
         including furniture used exclusively by the sublessee or
sub-sublessee,
         respectively,  shall be transferred  to, or retained by,
such sublessee
         or sub-sublessee.

                  (iv) SHARED NON-U.S.  FACILITIES  WITH THIRD
PARTY LEASES.  In
         the case of any real property or leasehold interests
located outside of
         the  United  States  covered  by an  Ancillary
Agreement  set forth on
         Schedule  2.5 that is a sublease  or  sub-sublease,  all
such  tangible
         property   will  be  retained  by  the   sublessor  or
sub-sublessor,
         respectively,  under the applicable  sublease or
sub-sublease,  except
         that  any such  tangible  property  (other  than  tenant
improvements,
         fixtures,  furniture and artwork) used  exclusively by
the sublessee or
         sub-sublessee,  respectively,  shall be transferred to,
or retained by,
         such sublessee or sub-sublessee.

In the case of this Section 2.5(b),  all  determinations  as to exclusive use by
any member of a Group shall be made without  regard to infrequent and immaterial
use by the members of any other Group,  if the transfer of such Asset to, or the
retention of such Asset by, such first Group would not interfere in any material
respect  with  either  the  business  or  operations  of any such  other  Group.
Notwithstanding  the foregoing  provisions of this Section  2.5(b),  any artwork
located as of the date  hereof in the  private  office of any senior  manager or
officer of any Group may, at the election of such senior manager or officer,  be
retained by, or transferred to, the Group by which such executive is employed as
of the Closing Date.

                  (c) In the case of any real  property  or  leasehold  interest
that is covered by Section  2.5(b)(i)  and any of Section  2.5(b)(ii),  (iii) or
(iv),  all such  tangible  property  shall  first be  allocated  pursuant to the
provisions  of Section  2.5(b)(i) and  thereafter  pursuant to whichever of such
other clauses is applicable.

                  2.6. DOCUMENTS RELATING TO OTHER TRANSFERS OF
ASSETS AND
ASSUMPTION OF LIABILITIES. In furtherance of the assignment,
transfer and
conveyance of Lucent Assets and the assumption of Lucent
Liabilities set forth
in Section 2.1(a) and (b), simultaneously


<PAGE>

with the execution and delivery hereof or as promptly as practicable thereafter,
(i) each of AT&T and NCR shall  execute  and  deliver,  and each shall cause its
respective  Subsidiaries  to execute  and  deliver,  such  bills of sale,  stock
powers, certificates of title, assignments of contracts and other instruments of
transfer,  conveyance and assignment as and to the extent  necessary to evidence
the  transfer,  conveyance  and  assignment  of all of  AT&T's,  NCR's and their
respective  Subsidiaries'  right, title and interest in and to the Lucent Assets
to Lucent and (ii) Lucent  shall  execute and  deliver,  to AT&T,  NCR and their
respective Subsidiaries such bills of sale, stock powers, certificates of title,
assumptions  of contracts  and other  instruments  of  assumption  as and to the
extent  necessary to evidence the valid and  effective  assumption of the Lucent
Liabilities by Lucent.

                  2.7. OTHER ANCILLARY AGREEMENTS. (a) Effective
as of the date
hereof, except as provided in Section 2.7(b) or Section 2.8, each
of AT&T,
Lucent and NCR will execute and deliver all Ancillary Agreements
to which it is
a party.


               (b) Effective as of March 29, 1996, the parties shall execute and
deliver each of the following Ancillary Agreements to which it is a party:

                  (i) the Patent Assignments and related
agreements regarding
         powers of attorney;

                  (ii) the Patent License Agreement;

                  (iii) the Patent Joint Ownership Agreement;

                  (iv) the Patent Defensive Protection Agreements;

                  (v) the Technology Assignment and Joint
Ownership Agreements;
         and

                  (vi) the Technology License Agreement.

                  (a) 2.8. THE NON-U.S. PLAN. (a) Each of AT&T,
Lucent and NCR
shall take, and shall cause each member of its respective Group to
take, such
action as reasonably necessary to consummate the transactions
contemplated by
the Non-U.S. Plan (whether prior to or after the Closing Date).
Notwithstanding
anything in this Agreement or in any Ancillary Agreement to the
contrary, no
party shall be entitled to receive or retain any Asset unless such
party shall
have paid any consideration contemplated to be paid in connection
therewith
pursuant to the Non-U.S. Plan.


                  (b) After the date hereof and on or prior to the Closing Date,
AT&T shall  transfer  all of its right,  title and interest in and to all of the
issued and outstanding  capital stock in each of ATTI and NCS Ventures,  Inc., a
Delaware corporation, to Lucent by means of a contribution of such capital stock
by AT&T to Lucent.  The parties hereto shall  execute,  or cause to be executed,
such transfer  instruments  as they mutually deem  appropriate to effectuate and
evidence such transfer.

                  2.9. AT&T VENTURES; LUCENT FOUNDATION.  (a) On or prior to the
Closing Date,  AT&T shall transfer to Lucent 35% of AT&T's interest as a limited
partner in AT&T  Ventures and Lucent shall assume all  Liabilities  of a limited
partner of AT&T Ventures  relating to such  interest.  AT&T and Lucent shall use
reasonable  best  efforts to  cooperate  so that Lucent will be admitted to AT&T
Ventures as a limited partner in respect of such interest.  Without  duplication
of any such Liability assumed in its capacity as a limited


<PAGE>

partner,  Lucent shall indemnify,  defend and hold harmless each AT&T Indemnitee
and each NCR Indemnitee  from and against 35% of any and all  Liabilities of the
AT&T Indemnitees or the NCR Indemnitees,  respectively, relating to, arising out
of or resulting from AT&T Ventures, including in respect of any capital calls or
commitments and in connection with the operation or management thereof.

                  (b) (i) Following the date hereof,  Lucent will  incorporate a
private foundation to be qualified under Section 501(c)(3) of the Code. The AT&T
Foundation  will  make an $18  million  grant to the new  foundation  formed  by
Lucent,  as soon as is reasonably  practicable  following such new  foundation's
request,  subject to the  satisfaction  by such new  foundation of the following
requirements:  the election or appointment of a governing  board of directors or
trustees,  the  adoption of by-laws,  the hiring of a  professional  staff,  the
formulation  of a mission  statement,  and  commencement  of the  development of
programs and priorities for funding grants. The determination as to whether such
requirements  have  been  satisfied  shall be made by the  trustees  of the AT&T
Foundation in their sole  discretion  and shall be binding on all parties.  Such
$18 million grant shall be payable, at the AT&T Foundation's  election,  in cash
or in appreciated property (or any combination thereof). All determinations with
respect to the fair market value of any appreciated property will be made by the
trustees of the AT&T Foundation in their sole discretion and shall be binding on
all parties.

                  (ii) The AT&T Foundation has approved a 1996 grant budget that
includes grants totalling $13 million relating to Lucent initiatives. The staffs
of the AT&T Foundation and the new foundation to be formed by Lucent pursuant to
subparagraph  (i) above will work together to administer the grants  relating to
these  Lucent  initiatives.  In the event  such $13  million  has not been fully
disbursed prior to the  Distribution  Date, the AT&T Foundation will transfer to
the new  foundation  formed by Lucent an amount equal to the portion of such $13
million  that has not  been  disbursed,  and such  foundation  will  assume  the
obligation to make grants equal to such remaining  amount.  The AT&T  Foundation
will also  allocate  up to $1  million  of its 1996  administrative  budget  for
administrative costs related to Lucent programs.

                  2.10.  DISCLAIMER OF REPRESENTATIONS AND WARRANTIES.  (a) Each
of AT&T (on behalf of itself and each member of the AT&T Services Group), Lucent
(on behalf of itself and each member of the Lucent  Group) and NCR (on behalf of
itself and each member of the NCR Group)  understands and agrees that, except as
expressly  set forth herein  (including  in Section  7.2(g)) or in any Ancillary
Agreement,  no party to this  Agreement,  any  Ancillary  Agreement or any other
agreement or document contemplated by this Agreement, any Ancillary Agreement or
otherwise, is representing or warranting in any way as to the Assets, businesses
or Liabilities  transferred or assumed as contemplated  hereby or thereby, as to
any consents or approvals required in connection  therewith,  as to the value or
freedom from any Security  Interests  of, or any other  matter  concerning,  any
Assets of such party, or as to the absence of any defenses or right of setoff or
freedom from  counterclaim  with respect to any claim or other Asset,  including
any accounts  receivable,  of any party,  or as to the legal  sufficiency of any
assignment,  document or instrument  delivered  hereunder to convey title to any
Asset or thing of value  upon the  execution,  delivery  and  filing  hereof  or
thereof.  Except  as may  expressly  be set  forth  herein  or in any  Ancillary
Agreement, all such Assets are being transferred on an "as is," "where is" basis
(and, in the case of any real property,  by means of a quitclaim or similar form
deed or conveyance) and the respective  transferees  shall bear the economic and
legal risks that any conveyance  shall prove to be  insufficient  to vest in the
transferee good and marketable title, free and clear of any Security Interest.


<PAGE>

                  2.11. FINANCING  ARRANGEMENTS.  (a) Prior to the Closing Date,
AT&T and Lucent shall enter into the Financing  Facility.  AT&T and Lucent agree
to take all such reasonable  action as may be necessary to permit AT&T to borrow
such amount as it shall  determine  under the  Financing  Facility  prior to the
Closing Date and to assure the assignment to and the assumption by Lucent of all
obligations  thereunder  and the full release and  discharge of each of AT&T and
any other member of the AT&T Group of all of its  obligations  thereunder  as of
the Closing Date in accordance  with the terms of the Financing  Facility.  AT&T
and  Lucent  shall   participate  in  the   preparation  of  all  materials  and
presentations  as may be reasonably  necessary to secure funding pursuant to the
Financing Facility,  including rating agency  presentations  necessary to obtain
the  requisite  ratings  needed  to secure  the  financing  under the  Financing
Facility and such assignment,  assumption, release and discharge. As of the time
of such assignment,  assumption, release and discharge, AT&T shall pay all third
party costs and  expenses  incurred  by any member of the AT&T Group  associated
with the Financing Facility.

                  (b)  Simultaneously   with  or  following  the  execution  and
delivery of this  Agreement,  Lucent  intends to enter into the Working  Capital
Facility.  Lucent agrees to cause all obligations of AT&T or any other member of
the AT&T Group, if any, under the Working  Capital  Facility to be terminated at
the Closing  Date.  Lucent  shall pay all expenses  associated  with the Working
Capital Facility.

                  2.12. GOVERNMENTAL APPROVALS AND CONSENTS. (a)
To the extent
that the Separation requires any Governmental Approvals or
Consents, the parties
will use their reasonable best efforts to obtain any such
Governmental Approvals
and Consents.

                  (b)  If and  to  the  extent  that  the  valid,  complete  and
perfected  transfer  or  assignment  (or  novation  of  any  federal  government
contract) to the Lucent Group of any Lucent  Assets (or from the Lucent Group of
any  Non-Lucent  Assets) would be a violation of applicable  laws or require any
Consent or Governmental  Approval in connection with the Separation,  the IPO or
the Distribution,  then, unless AT&T shall otherwise determine,  the transfer or
assignment  to or from the  Lucent  Group,  as the case may be,  of such  Lucent
Assets  or  Non-Lucent  Assets,  respectively,  shall  be  automatically  deemed
deferred and any such  purported  transfer or assignment  shall be null and void
until such time as all legal  impediments  are removed  and/or such  Consents or
Governmental Approvals have been obtained.  Notwithstanding the foregoing,  such
Asset shall be deemed an Lucent  Asset for purposes of  determining  whether any
Liability is an Lucent Liability.

                  (c) If the transfer or assignment of any Assets intended to be
transferred or assigned hereunder,  including pursuant to the Non-U.S.  Plan, is
not  consummated  prior to or at the  Closing  Date,  whether as a result of the
provisions of Section 2.12(b) or for any other reason, then the Person retaining
such Asset shall thereafter hold such Asset for the use and benefit,  insofar as
reasonably  possible,  of the Person  entitled  thereto  (at the  expense of the
Person entitled  thereto).  In addition,  the Person  retaining such Asset shall
take such other  actions as may be  reasonably  requested  by the Person to whom
such  Asset is to be  transferred  in order to place  such  Person,  insofar  as
reasonably possible,  in the same position as if such Asset had been transferred
as contemplated hereby and so that all the benefits and burdens relating to such
Lucent  Assets  (or such  Non-Lucent  Assets,  as the  case  may be),  including
possession,  use, risk of loss,  potential for gain,  and dominion,  control and
command  over such  Assets,  are to inure from and after the Closing Date to the
Lucent Group (or the AT&T Group, as the case may be).


<PAGE>

                  (d) If and when the Consents  and/or  Governmental  Approvals,
the absence of which  caused the  deferral of transfer of any Asset  pursuant to
Section  2.12(b),  are obtained,  the transfer of the applicable  Asset shall be
effected in accordance  with the terms of this  Agreement  and/or the applicable
Ancillary Agreement.

                  (e) The Person  retaining  an Asset due to the deferral of the
transfer of such Asset shall not be obligated, in connection with the foregoing,
to expend  any money  unless  the  necessary  funds are  advanced  by the Person
entitled to the Asset, other than reasonable out-of-pocket expenses,  attorneys'
fees and recording or similar fees, all of which shall be promptly reimbursed by
the Person entitled to such Asset.

                  2.13.  NOVATION  OF ASSUMED  LUCENT  LIABILITIES.  (a) Each of
AT&T,  Lucent  and NCR,  at the  request of any of the  others,  shall use their
reasonable  best  efforts to obtain,  or to cause to be  obtained,  any consent,
substitution,  approval or amendment  required to novate (including with respect
to any federal government  contract) or assign all obligations under agreements,
leases,  licenses and other obligations or Liabilities  (including Lucent OFL's)
of any nature  whatsoever  that constitute  Lucent  Liabilities or Nassau Metals
Liabilities, or to obtain in writing the unconditional release of all parties to
such  arrangements  other than any member of the Lucent  Group,  so that, in any
such  case,  Lucent and its  Subsidiaries  will be solely  responsible  for such
Liabilities;  provided,  however,  that  none of AT&T,  Lucent  or NCR  shall be
obligated  to pay any  consideration  therefor to any third party from whom such
consents, approvals, substitutions and amendments are requested.

                  (b) If AT&T, Lucent or NCR is unable to obtain, or to cause to
be obtained,  any such required  consent,  approval,  release,  substitution  or
amendment, the applicable member of the AT&T Services Group or the NCR Group, as
the case may be, shall continue to be bound by such agreements, leases, licenses
and other  obligations  and,  unless not  permitted by law or the terms  thereof
(except to the extent  expressly  set forth in Section 7.3 in the case of Lucent
OFL's),  Lucent shall,  as agent or  subcontractor  for AT&T,  NCR or such other
Person, as the case may be, pay, perform and discharge fully all the obligations
or other  Liabilities  of AT&T,  NCR or such other  Person,  as the case may be,
thereunder  from and after the date  hereof.  Lucent shall  indemnify  each AT&T
Indemnitee and each NCR Indemnitee,  and hold each of them harmless  against any
Liabilities  arising in connection  therewith.  Except as expressly set forth in
Section 7.3 in the case of Lucent  OFL's,  each of AT&T and NCR, as the case may
be, shall, without further consideration,  pay and remit, or cause to be paid or
remitted, to Lucent promptly all money, rights and other consideration  received
by it or any  member of its  respective  Group in  respect  of such  performance
(unless  any such  consideration  is an  Excluded  Asset).  If and when any such
consent, approval, release,  substitution or amendment shall be obtained or such
agreement,  lease, license or other rights or obligations shall otherwise become
assignable  or able to be  novated,  each of AT&T and  NCR,  as the case may be,
shall thereafter  assign, or cause to be assigned,  all its rights,  obligations
and other  Liabilities  thereunder or any rights or obligations of any member of
its respective  Group to Lucent  without  payment of further  consideration  and
Lucent  shall,  without the payment of any  further  consideration,  assume such
rights and obligations.

                  2.14.  NOVATION  OF  ASSUMED  LIABILITIES  OTHER  THAN  LUCENT
LIABILITIES.  (a) Each of AT&T,  Lucent  and NCR,  at the  request of any of the
others,  shall use their  reasonable  best efforts to obtain,  or to cause to be
obtained, any consent, substitution, approval or amendment required to novate or
assign all obligations under agreements,  leases, licenses and other obligations
or  Liabilities  of  any  nature   whatsoever  that  do  not  constitute  Lucent
Liabilities  or  Nassau  Metals  Liabilities,   or  to  obtain  in  writing  the
unconditional release of


<PAGE>

all parties to such  arrangements  other than any member of the AT&T  Group,  so
that, in any such case, the members of the AT&T Group will be solely responsible
for such Liabilities;  provided, however, that none of AT&T, Lucent or NCR shall
be obligated to pay any consideration therefor to any third party from whom such
consents, approvals, substitutions and amendments are requested.

                  (b) If AT&T, Lucent or NCR is unable to obtain, or to cause to
be obtained,  any such required  consent,  approval,  release,  substitution  or
amendment,  the applicable member of the Lucent Group shall continue to be bound
by such  agreements,  leases,  licenses and other  obligations  and,  unless not
permitted  by law or the terms  thereof,  AT&T shall  cause a member of the AT&T
Group,  as agent or  subcontractor  for such member of the Lucent Group, to pay,
perform and discharge  fully all the  obligations  or other  Liabilities of such
member of the Lucent Group thereunder from and after the date hereof. AT&T shall
indemnify  each Lucent  Indemnitee  and hold each of them  harmless  against any
Liabilities arising in connection  therewith.  Lucent shall cause each member of
the Lucent Group without further consideration, to pay and remit, or cause to be
paid or remitted,  to AT&T or to another  member of the AT&T Group  specified by
AT&T promptly all money,  rights and other  consideration  received by it or any
member of the Lucent Group in respect of such performance.  If and when any such
consent, approval, release,  substitution or amendment shall be obtained or such
agreement,  lease, license or other rights or obligations shall otherwise become
assignable or able to be novated,  Lucent shall promptly assign,  or cause to be
assigned,  all its rights,  obligations and other Liabilities  thereunder or any
rights or  obligations  of any member of the Lucent  Group to AT&T or to another
member  of  the  AT&T  Group  specified  by  AT&T  without  payment  of  further

                  2.15.  THIRD PARTY PATENT  LICENSE  AGREEMENTS.
(a) Except as
otherwise set forth in this Section 2.15,  effective as of the
date of execution
of the Patent Assignments and other agreements set forth in
Section 2.7(b), AT&T
hereby:  (i)  grants to each of Lucent  and NCR the right to share with AT&T the
license rights granted by any third party to AT&T pursuant to any patent license
agreement  between AT&T and such third party  existing as of the date hereof and
(ii) grants to Lucent the right to receive any net royalty  payments  from third
parties  pursuant  to the patent  license  agreements  referred to in clause (i)
above.  Except as otherwise set forth in this Section 2.15, AT&T will retain all
rights in and to the patent license agreements referred to in this Section 2.15.

                  (b) The  grants  set forth in the first  sentence  of  Section
2.15(a)  shall  not  apply to (i) the  patent  license  agreements  set forth in
Schedule  2.15(b) or (ii) any other  patent  license  agreement  with respect to
which there otherwise exists, on or prior to the date of execution of the Patent
Assignments,  written  provision  for the  allocation or sharing of rights under
such  patent  license  agreement  between or among any two or all three of AT&T,
Lucent and NCR.

                  (c) Except as set forth in Section 2.15(d),  in the event that
any grant of rights set forth in Section  2.15(a)  would  violate or is found to
violate the terms of, or result in the loss of rights or  imposition  of penalty
under, any patent license agreement  covered thereby,  or would not be effective
subsequent to the  Distribution  Date, such grant of rights with respect to such
patent license agreement shall be deemed null and void and, in lieu thereof, (i)
effective as of the  Distribution  Date,  AT&T hereby  transfers any such patent
license  agreement  to Lucent  without  retaining  any rights  therein (and AT&T
waives any


<PAGE>

such right it could  otherwise  retain) and (ii) Lucent shall use all reasonable
efforts to arrange for the grant by the  applicable  third  party of  comparable
rights  (other than any right to receive  royalty  payments) to each of AT&T and
NCR,  provided  that none of Lucent,  AT&T or NCR shall be  obligated to pay any
consideration therefor.

                  (d) In the  event  that any  transfer  set  forth  in  Section
2.15(c) would violate or is found to violate the terms of, or result in the loss
of rights or imposition of penalty under, any patent license  agreement  covered
thereby,  or would not be effective  subsequent to the  Distribution  Date, such
transfer  shall be deemed  null and void and, in lieu  thereof,  (i) AT&T hereby
retains all rights under any such patent license  agreement,  (ii) AT&T will pay
over to Lucent any royalty payments it may receive from any third party pursuant
to any such patent  license  agreement  and (iii) AT&T shall use all  reasonable
efforts to arrange for the grant by the  applicable  third  party of  comparable
rights  (other  than any right to royalty  payments)  to each of Lucent and NCR,
provided  that  none  of  Lucent,  AT&T or NCR  shall  be  obligated  to pay any
consideration therefor.

                  (e) In the event that license  rights under any patent license
agreement  intended to be granted or  transferred  to Lucent  under this Section
2.15 are not  effectively  granted or  transferred  (including in the event such
grant or  transfer  is not  effective  after the  Distribution  Date  and/or the
parties  are unable to arrange  for the grant by the  applicable  third party of
comparable  license rights to Lucent),  then, at the written  request of Lucent:
(i) AT&T will  exercise any  have-made  rights it may have under the  applicable
third-party  license  agreement  to have Lucent  make,  and will  purchase  from
Lucent,  such  products  or other  materials  as  Lucent  may  direct  using the
applicable  third-party  patents as to which AT&T has such have-made  rights (at
the price and on the terms to be paid and  agreed to by the Person or Persons to
whom AT&T may be directed to sell such products or other  materials  pursuant to
the following clause (ii)); and (ii) following any such purchase, AT&T will sell
such products or other  materials to such Person or Persons,  on such terms,  as
may be  directed  by Lucent  (except  that AT&T will not be required to make any
representations,  warranties  or  commitments  in respect  thereof other than to
provide  to  such  Person  or  Persons  the   representations,   warranties  and
commitments of Lucent in respect thereof,  for which only Lucent,  and not AT&T,
will be  responsible).  In connection with the foregoing,  Lucent will cause the
Person  or  Persons  to  which  such  products  or other  materials  are sold to
acknowledge in writing that only Lucent and the members of the Lucent Group, and
not AT&T or any member of the AT&T Group,  will be responsible to such Person or
Persons in respect of such products or other materials.  Nothing in this Section
(e) shall be  construed  to  require  AT&T or any  member  of the AT&T  Group to
violate any applicable laws, rules or regulations of any Governmental Authority.

                  (f) In the  event  AT&T  makes  any  purchases  and  sales  as
directed by Lucent under the  foregoing  paragraph  (e),  then:  (i) Lucent will
promptly reimburse AT&T for all costs and expenses (including allocated costs of
in-house  counsel and other personnel) that AT&T or any member of the AT&T Group
may incur in connection  with such actions,  plus a fee of two percent (2%); and
(ii) Lucent will  indemnify and hold harmless AT&T and each AT&T  Indemnitee for
all Liabilities that may arise as a result of such actions (including any claims
by the purchaser of such products or materials, any loss incurred on the sale of
such products or materials by AT&T to the Person or Persons  directed by Lucent,
or arising  out of the  failure  of such  Person or  Persons  to  purchase  such
products or materials on the terms directed by Lucent,  and any claims  alleging
any infringement of any patent,  copyright,  trademark or  misappropriation of a
trade secret,  any product liability claims, and any other claims, in connection
with such products or materials).


<PAGE>

                  (g) Each of AT&T,  Lucent and NCR agrees that it will  fulfill
any  obligations  it may have to any third party  pursuant to the patent license
agreements to which the provisions of this Section 2.15 apply.

in this Agreement or any Ancillary Agreement to the contrary, the
rights granted
to Lucent and the members of the Lucent Group shall be subject to
the provisions

provides,  either directly or indirectly  (whether through any reseller or joint
venture or otherwise),  any  Telecommunications  Services of the type offered by
the AT&T Services Business as of the Closing Date, then:

                  (i)  pursuant  to  Section  2.5 and  Article  IX
of the  Brand
         License Agreement,  AT&T may, in its sole discretion,
terminate all or
         any  portion  of the rights  granted  to Lucent and the
members of the
         Lucent Group pursuant to the Brand License Agreement;

                  (ii) AT&T may, in its sole  discretion,
terminate  all or any

Agreement;

                  (iii) AT&T may, in its sole  discretion,
exercise  either the

the  Supplemental
         General Purchase Agreement,  dated as of the date
hereof,  between AT&T
         and Lucent;

                  (iv) AT&T may, in its sole  discretion,
terminate  all or any
         portion of the rights to patents and  technology  of AT&T
or any member
         of the AT&T Group granted to Lucent and the members of
the Lucent Group
         pursuant to the Patent  License  Agreement and the
Technology  License
         Agreement; and

                  (v) at  AT&T's  direction,  which  may be
given  in its  sole
         discretion, Lucent and the members of the Lucent Group
will reconvey to
         AT&T or any  member  of the AT&T  Group all of their
right,  title and
         interest in any and all patents and  technology  in which
Lucent or any
         member of the Lucent Group was granted an undivided
one-half  interest
         pursuant to the Patent  Assignments  or the  Technology
Assignment and
         Joint Ownership Agreement.

                  (c) Lucent and the  members of the Lucent  Group  shall not be
deemed  to offer,  furnish  or  provide,  either  directly  or  indirectly,  any
Telecommunications  Services  (and  Section  2.16(b)  will not apply)  solely by
virtue of either of the following:

                  (i) a passive  investment  by Lucent or any of
the  members of
         the  Lucent  Group  of,  in the  aggregate,  (A)  less

         ownership  interest in any Person that  offers,
furnishes  or provides
         Telecommunications  Services in the United  States or (B)
not more than
         15% of the ownership  interest in any Person that
offers,  furnishes or
         provides  Telecommunications  Services  solely  outside
of the  United
         States (it being understood that Telecommunications
Services operating
         outside the United States will be considered  solely
outside the United
         States notwithstanding the ability


<PAGE>

         of such  Telecommunications  Services to receive
transmissions from or
         send   transmissions   to  the   United   States,   so
long  as  such
         Telecommunications  Services  may  not be  used  to
send  and  receive
         transmissions solely within the United States); or

                  (ii) an  investment  by  Lucent or any of the
members  of the
         Lucent Group of, in the  aggregate,  not more than 40% of
the ownership
         interest in any Person outside the United States formed
for the purpose
         of  building  a  network  or  similar   system  for  the
provision  of
         Telecommunications  Services solely outside of the United
States, which
         network  or  system is built by Lucent  or any  members
of the  Lucent
         Group;  so long as Lucent and the  members of the Lucent
Group  divest
         such interest to, in the aggregate,  not more than 15% of
the ownership
         interest  in  such  Person  within  one  year  of
commencement  of the
         provision  of any  Telecommunications  Services  over
such  network  or
         system,  or such  longer  period as may be  necessary
to  permit  such
         reduction in interest and to which AT&T shall  consent,
which  consent
         will not be unreasonably withheld; or

                  (iii) the offer,  furnishing  or  provision  by
Lucent and the
         members  of  the  Lucent  Group,  either  directly  or
indirectly,  of
         Telecommunications  Services from which the  aggregate
revenues in any
         fiscal  year do not exceed one  percent of the
aggregate  revenues  of
         Lucent  and the  members  of the  Lucent  Group for such
fiscal  year,
         provided  that, in determining  whether such one percent
threshold has
         been met, any resale of Telecommunications Services
provided by AT&T or
         any  member of the AT&T  Group to Lucent  or any  member
of the  Lucent
         Group  pursuant to the VTNS  Agreement or any tariff or

discretion  that it
         will  own  at  least  80.1%  of the  outstanding  Lucent

         following the IPO on a fully diluted basis,  after giving
effect to the
         issuance of any shares of restricted stock or employee
stock options to
         any  employees  of  Lucent,  and all other  conditions
to  permit  the
         Distribution to qualify as a tax-free  distribution to
AT&T, Lucent and
         AT&T's  shareholders  shall, to the extent applicable as
of the time of
         the IPO, be satisfied and there shall be no event or
condition  that is

                                THE DISTRIBUTION

                  4.1. THE  DISTRIBUTION.  (a) Subject to Section 4.3 hereof, on
or prior to the  Distribution  Date,  AT&T  will  deliver  to the  Agent for the
benefit of holders of record of AT&T Common  Stock on the Record  Date, a single
stock  certificate,   endorsed  by  AT&T  in  blank,  representing  all  of  the
outstanding  shares of Lucent  Common  Stock then owned by AT&T or any member of
the AT&T Group, and shall cause the transfer agent for the shares of AT&T Common
Stock  to  instruct  the  Agent  to  distribute  on the  Distribution  Date  the

on the Record Date (or such holder's designated  transferee or transferees) will
be entitled to receive in the  Distribution  a number of shares of Lucent Common
Stock equal to the number of shares of AT&T Common  Stock held by such holder on
the Record Date multiplied by a fraction the numerator of which is the number of
shares of Lucent Common Stock  beneficially owned by AT&T or any other member of
the AT&T Group on the Record Date and the  denominator of which is the number of
shares of AT&T Common Stock outstanding on the Record Date.

                  (c) Lucent and AT&T,  as the case may be, will  provide to the
Agent all share  certificates and any information  required in order to complete
the Distribution on the basis specified above.


<PAGE>

                  4.2.  ACTIONS PRIOR TO THE  DISTRIBUTION.  (a) AT&T and Lucent
shall prepare and mail, prior to the  Distribution  Date, to the holders of AT&T
Common Stock, such information  concerning Lucent, its business,  operations and
management,  the  Distribution  and such other matters as AT&T shall  reasonably
determine  and as may be required  by law.  AT&T and Lucent  will  prepare,  and
Lucent  will,  to the  extent  required  under  applicable  law,  file  with the
Commission any such documentation and any requisite no action letters which AT&T
determines  are necessary or desirable to effectuate the  Distribution  and AT&T
and Lucent shall each use its  reasonable  best efforts to obtain all  necessary
approvals from the Commission with respect thereto as soon as practicable.

                  (b) AT&T and  Lucent  shall  take  all such  action  as may be
necessary or  appropriate  under the  securities  or blue sky laws of the United
States (and any comparable  laws under any foreign  jurisdiction)  in connection
with the Distribution.

                  (c) AT&T and Lucent shall take all reasonable  steps necessary
and  appropriate  to cause the  conditions  set forth in Section 4.3 (subject to
Sections  4.3(d))  to be  satisfied  and  to  effect  the  Distribution  on  the
Distribution Date.

                  (d)  Lucent  shall  prepare  and  file,   and  shall  use  its
reasonable best efforts to have approved,  an application for the listing of the
Lucent Common Stock to be distributed in the  Distribution on the NYSE,  subject
to official notice of distribution.

                  4.3.  CONDITIONS  TO  DISTRIBUTION.  The AT&T Board  currently
intends  to effect  the  Distribution  by  December  31,  1996.  Subject  to any
restrictions contained in the Underwriting Agreement,  the AT&T Board shall have
the sole discretion to determine the date of consummation of the Distribution at
any time after the Closing Date and on or prior to December 31, 1996. AT&T shall
be obligated to  consummate  the  Distribution  no later than December 31, 1996,
subject to the satisfaction, or waiver by the AT&T Board in its sole discretion,
of the  conditions set forth below.  In the event that any such condition  shall
not have been  satisfied or waived on or before  December  31, 1996,  AT&T shall
consummate  the   Distribution   as  promptly  as   practicable   following  the
satisfaction or waiver of all such conditions.

                  (a) a private letter ruling from the Internal
Revenue Service
         shall have been obtained,  and shall continue in effect,
to the effect
         that, among other things,  the Distribution  will qualify
as a tax-free
         distribution  for federal  income tax purposes under
Section 355 of the
         Code and the transfer to Lucent of the Lucent Assets and
the assumption
         by Lucent of the Lucent  Liabilities in connection  with
the Separation
         will not result in the recognition of any gain or loss to
AT&T,  Lucent
         or AT&T's or Lucent's shareholders for federal income tax
purposes, and
         such ruling shall be in form and substance  satisfactory
to AT&T in its
         sole discretion;

                  (b) any material Governmental Approvals and
Consents necessary
         to consummate the Distribution  shall have been obtained
and be in full
         force and effect;

                  (c) no  order,  injunction  or  decree  issued
by any court or
         agency  of  competent   jurisdiction   or  other  legal
restraint  or
         prohibition preventing the consummation of the
Distribution shall be in
         effect  and no other  event  outside  the  control  of
AT&T  shall have
         occurred  or failed to occur  that  prevents  the
consummation  of the
         Distribution; and


<PAGE>

                  (d) no  other  events  or  developments  shall
have  occurred
         subsequent  to the Closing  Date that,  in the judgment
of the Board of
         Directors of AT&T, would result in the  Distribution
having a material
         adverse effect on AT&T or on the shareholders of AT&T.

The  foregoing  conditions  are for the sole  benefit of AT&T and shall not give
rise to or create any duty on the part of AT&T or the AT&T Board of Directors to
waive or not waive any such condition.


                  4.4.  FRACTIONAL  SHARES.  As soon as  practicable  after  the
Distribution  Date, AT&T shall direct the Agent to determine the number of whole
shares and fractional  shares of Lucent Common Stock allocable to each holder of
record or  beneficial  owner of AT&T  Common  Stock as of the  Record  Date,  to
aggregate all such fractional  shares and sell the whole shares obtained thereby
at the  direction  of AT&T  either  to  AT&T,  in open  market  transactions  or
otherwise,  in each case at then prevailing  trading prices,  and to cause to be
distributed  to each such  holder  or for the  benefit  of each such  beneficial
owner, in lieu of any fractional  share,  such holder's or owner's ratable share
of the proceeds of such sale, after making appropriate  deductions of the amount
required to be withheld for federal  income tax purposes and after  deducting an
amount equal to all brokerage charges, commissions and transfer taxes attributed
to such sale.  AT&T and the Agent  shall use their  reasonable  best  efforts to
aggregate  the shares of AT&T  Common  Stock that may be held by any  beneficial
owner thereof through more than one account in determining the fractional  share
allocable to such beneficial owner.

                  4.5. THE LUCENT BOARD OF DIRECTORS. AT&T and Lucent shall each
take  all  actions  which  may be  required  to elect or  otherwise  appoint  as
directors  of  Lucent,  on or  prior to the  Distribution  Date,  persons  to be
designated  by a  nominating  committee of Lucent's  Board of  Directors  (which
nominating  committee  shall be  comprised of  individuals  who are at such time
neither  officers nor directors of AT&T) as additional or substitute  members of
the Board of Directors of Lucent on the Distribution Date.

failed to occur or any  conditions  existing  or alleged  to have  existed on or
before the Closing Date,  including in connection with the  transactions and all
other  activities  to  implement  any  of  the  Separation,   the  IPO  and  the
Distribution.

                  (c) Nothing  contained  in Section  5.1(a) or (b) shall impair
any right of any Person to enforce this  Agreement,  any Ancillary  Agreement or
any agreements,  arrangements,  commitments or understandings that are specified
in Section 2.4(b) or the applicable Schedules thereto not to terminate as of the
Closing Date, in each case in accordance  with its terms.  Nothing  contained in
Section 5.1(a) or (b) shall release any Person from:

                  (i) any Liability  provided in or resulting from
any agreement
         among any members of the AT&T Services  Group,  the
Lucent Group or the
         NCR  Group  that is  specified  in  Section  2.4(b)  or
the  applicable
         Schedules  thereto as not to terminate as of the Closing

to terminate as

                  (ii)  any   Liability,   contingent  or
otherwise,   assumed,
         transferred, assigned or allocated to the Group of which
such Person is
         a member in accordance  with,  or any other  Liability of
any member of
         any Group under, this Agreement or any Ancillary
Agreement;

                  (iii) any  Liability  for the  sale,  lease,
construction  or
         receipt of goods,  property or services purchased,
obtained or used in
         the ordinary  course of business by a member of one Group
from a member

         member of another Group;

                  (v) any  Liability  that the parties may have
with  respect to
         indemnification  or contribution  pursuant to this
Agreement for claims
         brought against the parties by third Persons,  which
Liability shall be
         governed by the provisions of this Article V


<PAGE>

         and Article VI and, if applicable, the appropriate
provisions of the
         Ancillary Agreements; or

                  (vi) any  Liability  the release of which would
result in the
         release of any Person  other than a Person  released
pursuant  to this
         Section  5.1;  provided  that the  parties  agree not to
bring  suit or
         permit any of their  Subsidiaries to bring suit against
any Person with
         respect  to any  Liability  to the  extent  that such
Person  would be
         released with respect to such Liability by this Section
5.1 but for the
         provisions of this clause (vi).

                  (d) Lucent shall not make,  and shall not permit any member of
the Lucent Group to make, any claim or demand,  or commence any Action asserting
any claim or demand, including any claim of contribution or any indemnification,
against AT&T, NCR or any member of the AT&T Services Group or NCR Group,  or any
other  Person  released  pursuant  to  Section  5.1(a),   with  respect  to  any
Liabilities  released pursuant to Section 5.1(a).  AT&T shall not, and shall not
permit any member of the AT&T Services  Group,  to make any claim or demand,  or
commence  any  Action  asserting  any claim or  demand,  including  any claim of
contribution or any indemnification,  against Lucent or any member of the Lucent
Group, or any other Person released pursuant to Section 5.1(b),  with respect to
any Liabilities  released  pursuant to Section 5.1(b).  NCR shall not, and shall
not permit any member of the NCR Group, to make any claim or demand, or commence
any Action asserting any claim or demand, including any claim of contribution or
any  indemnification,  against Lucent or any member of the Lucent Group,  or any
other  Person  released  pursuant  to  Section  5.1(b),   with  respect  to  any
Liabilities released pursuant to Section 5.1(b).

                  (e) It is the intent of each of AT&T, Lucent and NCR by virtue
of the provisions of this Section 5.1 to provide for a full and complete release
and  discharge of all  Liabilities  existing or arising from all acts and events
occurring  or failing to occur or alleged to have  occurred or to have failed to
occur and all  conditions  existing or alleged to have  existed on or before the
Closing Date,  between or among Lucent or any member of the Lucent Group, on the
one hand,  and AT&T,  NCR or any  member of the AT&T  Services  Group or the NCR
Group, on the other hand  (including any contractual  agreements or arrangements
existing or alleged to exist  between or among any such members on or before the
Closing Date),  except as expressly set forth in Section 5.1(c). At any time, at
the  request of any other  party,  each  party  shall  cause each  member of its
respective  Group to execute  and deliver  releases  reflecting  the  provisions
hereof.

                  5.2.  INDEMNIFICATION BY LUCENT. Except as provided in Section
5.4, Lucent shall  indemnify,  defend and hold harmless AT&T, each member of the
AT&T  Services  Group  and  each of their  respective  directors,  officers  and
employees,  and each of the heirs,  executors,  successors and assigns of any of
the foregoing  (collectively,  the "AT&T Indemnitees"),  and NCR, each member of
the NCR Group and each of their  respective  directors,  officers and employees,
and each of the heirs, executors, successors and assigns of any of the foregoing
(collectively, the "NCR Indemnitees"),  from and against any and all Liabilities
of the AT&T  Indemnitees  and the NCR  Indemnitees,  respectively,  relating to,
arising  out  of  or  resulting  from  any  of  the  following   items  (without
duplication):

                  (a) the  failure  of Lucent or any other  member
of the Lucent
         Group  or any  other  Person  to pay,  perform  or
otherwise  promptly
         discharge  any Lucent  Liabilities,  any Nassau Metals
Liabilities  or
         Lucent  Contract in accordance  with their  respective
terms,  whether
         prior to or after the Closing Date or the date hereof;


<PAGE>

                  (b) the Lucent Business, any Lucent Liability,
any Lucent
         Contract or any Nassau Metals Liabilities;

                  (c) any breach by Lucent or any member of the
Lucent Group of
         this Agreement or any of the Ancillary Agreements; and

                  (d) any untrue  statement  or alleged  untrue
statement  of a
         material fact or omission or alleged  omission to state a
material fact
         required  to be stated  therein  or  necessary  to make
the  statements
         therein not misleading,  with respect to all
information  contained in
         any IPO Registration Statement or Prospectus.

                  5.3.  INDEMNIFICATION  BY AT&T  AND BY  NCR.  (a)  AT&T  shall
indemnify,  defend and hold harmless Lucent, each member of the Lucent Group and
each of their  respective  directors,  officers and  employees,  and each of the
heirs, executors,  successors and assigns of any of the foregoing (collectively,
the  "Lucent  Indemnitees"),  from and against  any and all  Liabilities  of the
Lucent  Indemnitees  relating to,  arising out of or  resulting  from any of the
following items (without duplication):

                  (i) the failure of AT&T or any other  member of
the AT&T Group
         or any other Person to pay, perform or otherwise promptly
discharge any
         Liabilities  of the AT&T Group other than the Lucent
Liabilities,  the
         Nassau  Metals  Liabilities  and the NCR Covered
Liabilities,  whether
         prior to or after the Closing Date or the date hereof;

                  (ii) the AT&T  Services  Business or any
Liability of the AT&T
         Group other than the Lucent Liabilities,  the Nassau
Metals Liabilities
         and the NCR Covered Liabilities; and

                  (iii) any  breach by AT&T or any  member of the
AT&T  Services
         Group of this Agreement or any of the Ancillary Agreements.

                  (b) NCR shall indemnify,  defend and hold harmless each Lucent
Indemnitee  from and against any and all  Liabilities of the Lucent  Indemnitees
relating  to,  arising  out of or  resulting  from  any of the  following  items
(without duplication):  (i) the failure of NCR or any member of the NCR Group or
any other Person to pay, perform or otherwise  promptly  discharge any Exclusive
NCR Contingent  Liability or any Shared NCR Percentage of any Shared  Contingent
Liability,  whether  prior to or after the Closing Date or the date hereof;  and
(ii) any breach by NCR or any member of the NCR Group of this  Agreement  or any
of the Ancillary Agreements,  or any other agreement that is not contemplated to
be terminated as of the Closing Date pursuant to Section  2.4(b)  (collectively,
the "NCR Covered Liabilities").

                  (c) NCR shall  indemnify,  defend and hold  harmless each AT&T
Indemnitee  from and against  any and all  Liabilities  of the AT&T  Indemnitees
relating to, arising out of or resulting from any NCR Covered
Liability.

                  5.4. INDEMNIFICATION OBLIGATIONS NET OF INSURANCE PROCEEDS AND
OTHER  AMOUNTS.   (a)  The  parties   intend  that  any  Liability   subject  to
indemnification  or reimbursement  pursuant to this Article V or Article VI will
be net of  Insurance  Proceeds  and any  amounts  recovered  pursuant to an RBOC
Agreement  that actually  reduce the amount of the Liability.  Accordingly,  the
amount  which any party (an  "Indemnifying  Party")  is  required  to pay to any
Person entitled to indemnification hereunder (an "Indemnitee") will be


<PAGE>

reduced by any Insurance Proceeds theretofore actually recovered by or on behalf
of the  Indemnitee  in  reduction  of the  related  Liability  and by any amount
actually theretofore  recovered pursuant to an RBOC Agreement.  If an Indemnitee
receives a payment (an "Indemnity  Payment")  required by this Agreement from an
Indemnifying  Party  in  respect  of any  Liability  and  subsequently  receives
Insurance Proceeds,  or recovers any amount pursuant to an RBOC Agreement,  then
the Indemnitee will pay to the Indemnifying  Party an amount equal to the excess
of the Indemnity  Payment received over the amount of the Indemnity Payment that
would have been due if the Insurance Proceeds and/or RBOC Agreement recovery had
been received, realized or recovered before the Indemnity Payment was made.

                  (b) In  the  case  of any  Shared  Contingent  Liability,  any
Insurance  Proceeds,  or  recoveries  pursuant  to any RBOC  Agreement  actually
received, realized or recovered by any party in respect of the Shared Contingent
Liability will be shared among the parties in such manner as may be necessary so
that the obligations of the parties for such Shared Contingent Liability, net of
such Insurance  Proceeds or recovery pursuant to an RBOC Agreement,  will remain
in proportion to their respective Shared Percentages,  regardless of which party
or parties may actually receive,  realize or recover such Insurance  Proceeds or
amount pursuant to an RBOC Agreement.

                  (c) An insurer who would  otherwise  be  obligated  to pay any
claim shall not be  relieved  of the  responsibility  with  respect  thereto or,
solely by virtue of the indemnification  provisions hereof, have any subrogation
rights with respect  thereto,  it being expressly  understood and agreed that no
insurer or any other third party shall be  entitled  to a  "windfall"  (i.e.,  a
benefit   they  would  not  be  entitled  to  receive  in  the  absence  of  the
indemnification  provisions) by virtue of the indemnification provisions hereof.
Nothing  contained in this Agreement or any Ancillary  Agreement  shall obligate
any member of any Group to seek to collect or recover any Insurance Proceeds.

                  5.5. PROCEDURES FOR INDEMNIFICATION OF THIRD PARTY CLAIMS. (a)
If an Indemnitee  shall receive notice or otherwise  learn of the assertion by a
Person  (including any  Governmental  Authority) who is not a member of the AT&T
Services  Group,  the  Lucent  Group  or the NCR  Group  of any  claim or of the
commencement  by any such  Person of any Action  (collectively,  a "Third  Party
Claim") with respect to which an Indemnifying  Party may be obligated to provide
indemnification to such Indemnitee  pursuant to Section 5.2 or 5.3, or any other
Section of this Agreement or any Ancillary Agreement, such Indemnitee shall give
such Indemnifying Party and, if AT&T is not the Indemnifying Party, AT&T written
notice  thereof  within 20 days after  becoming aware of such Third Party Claim.
Any such notice shall  describe the Third Party Claim in reasonable  detail.  If
any Person shall receive  notice or otherwise  learn of the assertion of a Third
Party  Claim  which  may  reasonably  be  determined  to be a Shared  Contingent
Liability,  such Person (if other than AT&T) shall give AT&T and any other party
to this Agreement  written notice thereof within 20 days after becoming aware of
such Third Party Claim.  Any such notice shall describe the Third Party Claim in
reasonable detail.  Notwithstanding the foregoing, the failure of any Indemnitee
or other  Person to give  notice as provided in this  Section  5.5(a)  shall not
relieve the related  Indemnifying Party of its obligations under this Article V,
except to the extent that such Indemnifying Party is actually prejudiced by such
failure to give notice.


                  (b) If the Indemnitee, the party receiving any notice pursuant
to Section 5.5(a) or any other party to this  Agreement  believes that the Third
Party Claim is or may be a Shared Contingent Liability, such Indemnitee or other
party may make a Determination


<PAGE>

Request  at  any  time  following  any  notice  given  by the  Indemnitee  to an
Indemnifying  Party or given by any other  Person to AT&T  pursuant  to  Section
5.5(a).  AT&T may make such a  Determination  Request  at any time.  Unless  all
parties have  acknowledged  that the applicable Third Party Claim (including any
Third  Party  Claim  set  forth  on  Schedule  6.6) is not a  Shared  Contingent
Liability or unless a  determination  to such effect has been made in accordance
with  Section  6.6,  AT&T shall be entitled  (but not  obligated)  to assume the
defense  of  such  Third  Party  Claim  as if it  were  the  Indemnifying  Party
hereunder. In any such event, AT&T shall be entitled to reimbursement of all the
costs and  expenses  (including  allocated  costs of in-house  counsel and other
personnel) of such defense once a final  determination or acknowledgment is made
as to the status of the Third Party Claim from the  applicable  party or parties
that would  have been  required  to pay such  amounts if the status of the Third
Party Claim had been determined immediately;  provided that, if such Third Party
Claim is determined to be a Shared Contingent Liability, such costs and expenses
shall be shared as provided in Section 5.5(c).

                  (c) AT&T shall  assume the  defense of, and may seek to settle
or compromise,  any Third Party Claim that is a Shared Contingent Liability, and
the costs and expenses (including  allocated costs of in-house counsel and other
personnel)  thereof  shall be included in the  calculation  of the amount of the
applicable  Shared   Contingent   Liability  in  determining  the  reimbursement
obligations of the other parties with respect  thereto  pursuant to Section 6.4.
Any Indemnitee in respect of a Shared Contingent  Liability shall have the right
to employ separate  counsel and to participate in (but not control) the defense,
compromise,  or  settlement  thereof,  but all fees and expenses of such counsel
shall be the expense of such Indemnitee.

                  (d) Other than in the case of a Shared  Contingent  Liability,
an Indemnifying  Party may elect to defend (and,  unless the Indemnifying  Party
has specified any reservations or exceptions,  to seek to settle or compromise),
at such Indemnifying  Party's own expense and by such  Indemnifying  Party's own
counsel,  any Third Party Claim. Within 30 days after the receipt of notice from
an  Indemnitee in accordance  with Section  5.5(a) (or sooner,  if the nature of
such Third Party Claim so  requires),  the  Indemnifying  Party shall notify the
Indemnitee  of  its  election  whether  the   Indemnifying   Party  will  assume
responsibility  for  defending  such Third Party  Claim,  which  election  shall
specify any reservations or exceptions.  After notice from an Indemnifying Party
to an  Indemnitee  of its election to assume the defense of a Third Party Claim,
such  Indemnitee  shall  have  the  right  to  employ  separate  counsel  and to
participate in (but not control) the defense, compromise, or settlement thereof,
but the  fees  and  expenses  of  such  counsel  shall  be the  expense  of such
Indemnitee  except as set forth in the next sentence.  In the event that (i) the
Third Party Claim is not a Shared Contingent Liability and (ii) the Indemnifying
Party has  elected  to assume  the  defense  of the  Third  Party  Claim but has
specified,  and  continues to assert,  any  reservations  or  exceptions in such
notice, then, in any such case, the reasonable fees and expenses of one separate
counsel for all Indemnitees shall be borne by the Indemnifying Party.

                  (e) Other than in the case of a Shared  Contingent  Liability,
if an  Indemnifying  Party elects not to assume  responsibility  for defending a
Third Party Claim,  or fails to notify an Indemnitee of its election as provided
in Section 5.5(d), such Indemnitee may defend such Third Party Claim at the cost
and expense (including  allocated costs of in-house counsel and other personnel)
of the Indemnifying Party.

                  (f)  Unless  the  Indemnifying  Party has failed to assume the
defense of the Third Party Claim in accordance with the terms of this Agreement,
no Indemnitee may


<PAGE>

settle or  compromise  any Third  Party  Claim  that is not a Shared  Contingent
Liability  without the consent of the  Indemnifying  Party.  No  Indemnitee  may
settle or compromise any Third Party Claim that is a Shared Contingent Liability
without the consent of AT&T.

                  (g) In the case of a Third  Party  Claim  that is not a Shared
Contingent  Liability,  no  Indemnifying  Party  shall  consent  to entry of any
judgment  or enter into any  settlement  of the Third  Party  Claim  without the
consent of the  Indemnitee  if the effect  thereof is to permit any  injunction,
declaratory  judgment,  other order or other  nonmonetary  relief to be entered,
directly or  indirectly,  against any  Indemnitee.  In the case of a Third Party
Claim that is a Shared Contingent Liability,  AT&T shall not consent to entry of
any judgment or enter into any  settlement  of the Third Party Claim without the
consent of the  Indemnitee  if the effect  thereof is to permit any  injunction,
declaratory  judgment,  other order or other  nonmonetary  relief to be entered,
directly or indirectly, against any Indemnitee.

                  (h) The  provisions  of Section  5.5 and Section 5.6 shall not
apply to Taxes (which are covered by the Tax Sharing Agreement).

                  5.6.  ADDITIONAL  MATTERS.  (a)  Any  claim  on  account  of a
Liability  which does not result  from a Third  Party Claim shall be asserted by
written notice given by the Indemnitee to the related  Indemnifying  Party. Such
Indemnifying  Party  shall  have a period of 30 days  after the  receipt of such
notice  within which to respond  thereto.  If such  Indemnifying  Party does not
respond within such 30-day period,  such  Indemnifying  Party shall be deemed to
have refused to accept  responsibility  to make  payment.  If such  Indemnifying
Party does not respond  within such 30-day period or rejects such claim in whole
or in part,  such  Indemnitee  shall be free to pursue  such  remedies as may be
available to such party as  contemplated  by this  Agreement  and the  Ancillary
Agreements.

                  (b)  In  the  event  of   payment  by  or  on  behalf  of  any
Indemnifying  Party to any Indemnitee in connection  with any Third Party Claim,
such  Indemnifying  Party shall be subrogated to and shall stand in the place of
such  Indemnitee  as to any  events or  circumstances  in  respect of which such
Indemnitee  may have any right,  defense or claim  relating  to such Third Party
Claim  against any  claimant or  plaintiff  asserting  such Third Party Claim or
against any other person. Such Indemnitee shall cooperate with such Indemnifying
Party in a reasonable manner,  and at the cost and expense (including  allocated
costs of in-house  counsel and other personnel) of such  Indemnifying  Party, in
prosecuting any subrogated right, defense or claim; provided, however, that AT&T
shall be entitled to control the prosecution of any such right, defense or claim
in respect of any Shared Contingent Liability.


                  (c) In the event of an Action in which the Indemnifying  Party
is not a named defendant,  if either the Indemnified Party or Indemnifying Party
shall so request,  the parties  shall  endeavor to substitute  the  Indemnifying
Party for the named defendant or, in the case of a Shared Contingent  Liability,
add the Indemnifying Party as a named defendant, if at all practicable.  If such
substitution  or addition cannot be achieved for any reason or is not requested,
the named defendant shall allow the  Indemnifying  Party to manage the Action as
set forth in this  Section  and,  subject to Section 6.4 with  respect to Shared
Contingent  Liabilities,  the Indemnifying Party shall fully indemnify the named
defendant  against all costs of  defending  the Action  (including  court costs,
sanctions  imposed  by a court,  attorneys'  fees,  experts'  fees and all other
external  expenses,  and the  allocated  costs of  in-house  counsel  and  other
personnel),  the  costs  of any  judgment  or  settlement,  and the  cost of any
interest or penalties relating to any judgment or settlement.

                  5.7.  REMEDIES  CUMULATIVE.  The  remedies  provided  in  this
Article V shall be  cumulative  and,  subject to the  provisions  of Article IX,
shall not  preclude  assertion  by any  Indemnitee  of any  other  rights or the
seeking of any and all other remedies against any Indemnifying Party.

                  5.8.  SURVIVAL OF  INDEMNITIES.  The rights and obligations of
each of AT&T, Lucent and NCR and their respective Indemnitees under this Article
V shall  survive  the sale or other  transfer  by any  party  of any  Assets  or
businesses or the assignment by it of any Liabilities.

                  5.9. RBOC AGREEMENT  PROCEDURES.  (a) With respect to the RBOC
Agreements, and except as otherwise provided in this Section 5.9 or as otherwise
agreed by the  parties  hereto,  AT&T shall be the party to provide  and receive
notices and all other  information to and from the RBOCs,  and otherwise to deal
with the RBOCs,  in respect of all matters  arising under the RBOC Agreements or
the RBOC Plan.  Without  limiting  the  foregoing,  AT&T shall  continue  as the
representative of all Groups to the contingent  liability  oversight  committee,
except as and to the extent  AT&T and the other  parties to the RBOC  Agreements
may otherwise agree.

                  (b) After the date hereof, AT&T and Lucent will cooperate with
each other to take reasonable  steps to transfer to Lucent the  responsibilities
for providing and receiving  notices and other  information to and from, and for
otherwise  dealing  with,  the RBOCs in  respect of Lucent  Liabilities  and any
Nassau  Metals  Liabilities  that may be subject to sharing with the RBOCs under
any RBOC Agreements  (other than Shared  Contingent  Liabilities,  which will be
controlled  by AT&T in  accordance  with  the  provisions  of  Section  5.5(c)),
including the right to receive directly from the RBOCs any sharing payments that
may be due from the  RBOCs  under  any RBOC  Agreements  in  respect  of  Lucent
Liabilities or Nassau Metals Liabilities. Unless and until such responsibilities
are  transferred to Lucent in accordance  with the foregoing,  the provisions of
the following paragraphs (c), (d) and (e) will apply.

                  (c) In the  event  that  Lucent  determines  that  any  Lucent
Liability  or any  Nassau  Metals  Liability  (other  than a  Shared  Contingent
Liability)  is or may be subject to sharing with the RBOCs  pursuant to any RBOC
Agreement,  and Lucent so requests,  AT&T will promptly submit any notice, claim
or other information or material with respect thereto as may be required by such
RBOC  Agreement  and  provided by Lucent to AT&T in  accordance  with the notice
provisions  of Section 12.5  hereof.  Upon receipt of any amounts from any RBOCs
with respect to their sharing  obligation under an RBOC Agreement relating to an
Lucent Liability or any Nassau Metals Liability (other than a Shared  Contingent
Liability),  AT&T will  promptly  remit such  amounts to Lucent.  AT&T will also
forward to Lucent,  in  accordance  with the notice  provisions  of Section 12.5
hereof, any notices, information or other materials that it may receive from the
RBOCs pursuant to such RBOC Agreement in respect of any Lucent  Liability or any
Nassau Metals Liability.  Notwithstanding the foregoing,  in no event shall AT&T
have any liability for its failure or delay in submitting or forwarding any such
notice,  claim,  information  or other  material  except to the extent Lucent is
prejudiced  thereby.  AT&T shall have no obligation to send, deliver or make any
such  notice or claim,  or take any other  action  under any RBOC  Agreement  in
respect of any Lucent  Liability or any Nassau Metals  Liability,  unless Lucent
shall request that AT&T do so, and provide AT&T with any necessary notice, claim
or other information or material, as set forth above.


<PAGE>

                  (d) In the event any  member of the  Lucent  Group  desires to
commence an arbitration  or other  proceeding to recover any amounts that may be
due under any RBOC  Agreement  in respect of an Lucent  Liability  or any Nassau
Metals Liability (other than a Shared Contingent Liability), AT&T will take such
action as such  member of the Lucent  Group may  reasonably  request to commence
such  arbitration or other  proceeding in accordance  with such RBOC  Agreement,
including  consenting  to be the  named  party  in  such  arbitration  or  other
proceeding,  but  such  arbitration  or other  proceeding  will be  managed  and
controlled  by such  member of the  Lucent  Group and such  member of the Lucent
Group will be  responsible  for the  prosecution  of such  arbitration  or other
proceeding and all decisions made with respect thereto.

                  (e)  Lucent  will,  upon  receipt  of  any  invoice  therefor,
promptly reimburse AT&T for all costs or expenses (including  allocated costs of
in-house counsel and other personnel) incurred in taking any actions pursuant to
the  foregoing  paragraphs  (c) and (d),  and will  defend,  indemnify  and hold
harmless AT&T and each other AT&T  Indemnitee  with respect to all matters taken
at the direction of or on behalf of any member of the Lucent Group in connection
with any RBOC Agreement.

                  (f) Each party hereto further agrees that it will from time to
time  promptly  provide  AT&T  with  all such  information,  notices  and  other
materials  (and shall make available the former,  current and future  directors,
officers, employees, other personnel and agents of the members of its respective
Group as witnesses and any books,  records or other documents within its control
or which it otherwise  has the ability to make  available) as AT&T may determine
to be  necessary  or  advisable to permit AT&T to pursue any rights or potential
rights under each such RBOC Agreement,  to perform the obligations of any member
of the AT&T  Group  under  each  such  RBOC  Agreement  in  accordance  with the
respective  terms thereof and to defend  itself,  its  Affiliates  and any other
Person   for  which  AT&T  may  have  any   indirect   liability   (through   an
indemnification  obligation  or otherwise)  from any claims or potential  claims
thereunder.

                  5.10.  ALLEGED  INFRINGEMENT  OR  MISAPPROPRIATION.   (a)  The
provisions of this Section 5.10 shall apply notwithstanding any other provisions
of this Agreement or any Ancillary Agreement. In the event of any claim, action,
proceeding  or suit by a third  party  against  any  member  of the  AT&T  Group
alleging an infringement of any patent, copyright, trademark or misappropriation
of a trade  secret  with  respect to any  product,  software  or other  material
provided by or ordered from the Lucent Business prior to the Closing Date (other
than any such product,  software or other  material  provided  under and ordered
pursuant to the AT&T General Purchase Agreement,  or any supplemental or related
agreement  thereto,  with respect to which an infringement  or  misappropriation
indemnity  is  provided  under  such  agreement)  for use by the  AT&T  Services
Business or the NCR  Business  (whether  used alone or in  combination  with any
product,  software or other  material  provided  by the Lucent  Business or by a
third party),  Lucent, at its expense,  shall defend and hold harmless each such
member of the AT&T Group with respect to such claim, action, proceeding or suit,
subject to the conditions and exceptions  stated in paragraphs  (b), (c) and (d)
below.  Lucent shall reimburse each such member of the AT&T Group for all costs,
expenses or attorneys' fees (including  allocated costs of in-house  counsel and
other  personnel)  incurred at Lucent's  written request or  authorization,  and
shall  indemnify  each  such  member of the AT&T  Group  against  any  liability
assessed  against  it by final  judgment,  on account  of such  infringement  or
misappropriation arising out of such use.

                  (b) If the use by any  member  of the  AT&T  Group of any such
product,  software or other material  referred to in Section 5.10(a) is enjoined
or in the opinion of


<PAGE>

such member of the AT&T Group is likely to be  enjoined,  Lucent  shall,  at its
expense and at the sole option of such member of the AT&T Group, (i) replace the
enjoined  product,   software  or  materials  with  a  substitute  free  of  any
infringement;  (ii) modify the enjoined  product,  software or materials so that
they will be free of the  infringement;  or (iii) procure for such member of the
AT&T Group a license or other  right to use the  enjoined  product,  software or
materials. In the alternative, such member of the AT&T Group, may at its option,
procure a license  with a  reasonable  royalty  rate  payable to the third party
alleging infringement,  and Lucent shall reimburse,  indemnify and hold harmless
such member of the AT&T Group for all liability  for payment of such  reasonable
royalty.

                  (c) AT&T or another member of the AT&T Group shall give Lucent
prompt written notice of all such claims, actions, proceedings or suits alleging
infringement  or  misappropriation  and  Lucent  shall  have  full and  complete
authority to assume the sole defense thereof,  including appeals,  and to settle
the same; provided,  however,  that this does not limit any rights of any member
of the AT&T Group  concerning  injunctions  addressed  in Section  5.10(b).  The
members of the AT&T Group shall,  upon Lucent's request and at Lucent's expense,
furnish all  information  and  assistance  available to such members of the AT&T
Group and cooperate in every  reasonable  way to facilitate  the defense  and/or
settlement of any such claim, action, proceeding or suit.

                  (d) The  foregoing  indemnity  will not  apply to any  alleged
infringement or misappropriation if and to the extent such alleged  infringement
or  misappropriation  arises from (i) the use by any member of the AT&T Group of
any product,  software or other  material  provided by the Lucent  Business,  in
combination  with any product,  software or other  material  provided  after the
Closing Date by a third party  (other than any  third-party  product,  software,
other  material or components  furnished to such member of the AT&T Group by any
member of the Lucent Group),  or (ii) any changes made by any member of the AT&T
Group after the Closing  Date in any  combination  of any  product,  software or
other material  provided by the Lucent Business,  with any product,  software or
other material  provided by a third party (other than any  third-party  product,
software,  other material or components  furnished by the Lucent Group),  except
for the  addition of any  product,  software or other  material  provided by any
member of the Lucent  Group after the Closing  Date to any such  combination  in
place as of the Closing Date.

                                   ARTICLE VI
                   CONTINGENT GAINS AND CONTINGENT LIABILITIES

                  6.1. DEFINITIONS RELATING TO CONTINGENT GAINS
AND CONTINGENT
LIABILITIES. For the purpose of this Agreement the following terms
shall have
the following meanings:

                  (a) CONTINGENT  CLAIM COMMITTEE means a committee  composed of
one representative  designated from time to time by each of AT&T, NCR and Lucent
that shall be established in accordance with Section 6.6.

                  (b)  CONTINGENT  GAIN means any claim or other  right of AT&T,
Lucent, NCR or any their respective  Affiliates,  whenever arising,  against any
Person other than AT&T,  Lucent, NCR or any of their respective  Affiliates,  if
and to the  extent  that (i) such claim or right has  accrued as of the  Closing
Date (based on then existing law) and (ii) the


<PAGE>

existence or scope of the obligation of such other Person as of the Closing Date
was not  acknowledged,  fixed or  determined in any material  respect,  due to a
dispute  or other  uncertainty  as of the  Closing  Date or as a  result  of the
failure of such claim or other right to have been  discovered  or asserted as of
the Closing  Date. A claim or right meeting the  foregoing  definition  shall be
considered a Contingent Gain regardless of whether there was any Action pending,
threatened  or  contemplated  as of the Closing Date with respect  thereto.  For
purposes of the  foregoing,  a claim or right shall be deemed to have accrued as
of the Closing Date if all the elements of the claim necessary for its assertion
shall have  occurred  on or prior to the  Closing  Date,  such that the claim or
right,  were it asserted in an Action on or prior to the Closing Date, would not
be  dismissed  by a court on ripeness or similar  grounds.  Notwithstanding  the
foregoing,  none of (i) any payment to any member of any Group pursuant to or in
respect of any of the RBOC Agreements,  (ii) any Insurance  Proceeds,  (iii) any
Excluded  Assets,  (iv) any reversal of any litigation or other reserve,  or (v)
any matters relating to Taxes (which are governed by the Tax Sharing  Agreement)
shall deemed to be a Contingent Gain.

                  (c)  CONTINGENT  LIABILITY  means any  Liability,  other  than
Liabilities  for Taxes  (which are  governed by the Tax Sharing  Agreement),  of
AT&T, Lucent, NCR or any of their respective  Affiliates,  whenever arising,  to
any Person other than AT&T, Lucent,  NCR or any of their respective  Affiliates,
if and to the extent that (i) such  Liability has accrued as of the Closing Date
(based on then existing  law) and (ii) the existence or scope of the  obligation
of AT&T,  Lucent,  NCR or any of their  respective  Affiliates as of the Closing
Date with respect to such Liability was not acknowledged, fixed or determined in
any material  respect,  due to a dispute or other  uncertainty as of the Closing
Date or as a result of the failure of such Liability to have been  discovered or
asserted as of the Closing  Date (it being  understood  that the  existence of a
litigation  or  other  reserve  with  respect  to  any  Liability  shall  not be
sufficient  for  such  Liability  to  be  considered   acknowledged,   fixed  or
determined).  In the case of any  Liability a portion of which had accrued as of
the Closing Date and a portion of which  accrues  after the Closing  Date,  only
that  portion  that had accrued as of the  Closing  Date shall be  considered  a
Contingent Liability. For purposes of the foregoing, a Liability shall be deemed
to have  accrued as of the Closing Date if all the  elements  necessary  for the
assertion of a claim with respect to such  Liability  shall have  occurred on or
prior to the Closing Date, such that the claim, were it asserted in an Action on
or prior to the Closing  Date,  would not be dismissed by a court on ripeness or
similar grounds.  For purposes of  clarification  of the foregoing,  the parties
agree that no  Liability  relating  to,  arising  out of or  resulting  from any
obligation  of any Person to perform the  executory  portion of any  contract or
agreement  existing as of the Closing Date, or to satisfy any obligation accrued
under any Plan (as defined in the Employee Benefits Agreement) as of the Closing
Date, shall deemed to be a Contingent Liability.

                  (d)  EXCESS  PORTION  means  that  portion,  if  any,  of  the
aggregate  Value of all amounts  actually  paid by AT&T,  Lucent or NCR (in each
case,  together  with any members of its  respective  Group),  in respect of any
single  Exclusive  Contingent  Liability of such Group or any Related  Exclusive
Contingent Liabilities of such Group that is in excess of $100 million.

                  (e) EXCLUSIVE AT&T  CONTINGENT  GAIN means any
Contingent Gain
if such  Contingent  Gain  primarily  relates  to any  AT&T
Services  Business,

such  Contingent  Liability  is  expressly  assigned  to AT&T  pursuant  to this
Agreement or any Ancillary Agreement.

                  (i) EXCLUSIVE  CONTINGENT  LIABILITY  means any Exclusive AT&T
Contingent Liability, Exclusive NCR Contingent Liability or Exclusive Lucent
Contingent Liability.


                  (j) EXCLUSIVE LUCENT CONTINGENT LIABILITY means any Contingent
Liability  (other  than an RBOC  Liability)  if (i)  such  Contingent  Liability
primarily  relates to any Lucent  Business or to the matters listed or described
on Schedule  2.3(a)(v),  including  the matters  listed or described on Schedule
6.1(f) (as supplemented pursuant to Section 6.6(d)) hereto, (ii) such Contingent
Liability relates to, arises out of or results from any Nassau Metals Liability,
or (iii) such Contingent  Liability is expressly  assigned to Lucent pursuant to
this  Agreement or any Ancillary  Agreement.  The parties agree that the matters
specified on Schedule  6.1(f)(iv) shall be deemed  Exclusive  Lucent  Contingent
Liabilities to the extent reflected thereon.

                  (k) EXCLUSIVE NCR  CONTINGENT  LIABILITY  means any Contingent
Liability (other than an RBOC Liability) if such Contingent  Liability primarily

         Exclusive  Contingent  Liabilities of such Group (but not
including any
         Exclusive Contingent Liabilities of any other Group) arising from:

                           (A) any single Action (including any
group of Actions
                  that are  consolidated  as a single  Action  and
any Action or
                  Actions certified as a class action);

                           (B) any Action that is brought or
threatened to be
                  brought as a class action and that is settled; or

                           (C)  any  group  of  Actions   (other
than  workers'
                  compensation  Actions  by or on behalf  of
former or  current

                           (A) any and all Environmental
Liabilities of such
                  Group associated with a single site; and

                           (B)  any and all  Environmental
Liabilities  of such
                  Group arising from  separate  sites but listed
on the National
                  Priorities List as a single site.
Exclusive  Contingent
                  Liabilities of such Group that are
Environmental  Liabilities
                  of such Group  arising  from sites  listed
separately  on the
                  National  Priorities  List  shall not be deemed
to be  Related
                  Exclusive Contingent Liabilities.  Whether sites
not listed on
                  the National  Priorities  List shall be deemed
to be a "single
                  site" for purposes of clause (B) of this

state or local
                  Governmental  Authority  similar in import to
those authorized
                  by the definition of "on-site" in 40 C.F.R.
Section 300.5 (as
                  in effect as of the date of this Agreement)
shall similarly be
                  determinative  of  whether  sites not  listed on
the  National
                  Priorities  List  shall be deemed  to be a

                  6.2.  CONTINGENT GAINS. (a) Each of AT&T, Lucent and NCR shall
have sole and  exclusive  right to any  benefit  received  with  respect  to any
Exclusive AT&T Contingent Gain,  Exclusive  Lucent  Contingent Gain or Exclusive
NCR Contingent Gain, respectively.  Each of AT&T, Lucent and NCR shall have sole
and  exclusive  authority  to  commence,  prosecute,  settle,  manage,  control,
conduct, waive, forego, release, discharge,  forgive and otherwise determine all
matters whatsoever with respect to any Exclusive AT&T Contingent Gain, Exclusive
Lucent Contingent Gain or Exclusive NCR Contingent Gain, respectively.

                  (b)  Any  benefit  that  may  be  received   from  any  Shared
Contingent Gain shall be shared among AT&T,  Lucent and NCR in proportion to the
Shared  AT&T  Percentage,  the  Shared  Lucent  Percentage  and the  Shared  NCR
Percentage,  respectively,  and shall be paid in  accordance  with  Section 6.5.
Notwithstanding  the foregoing,  AT&T shall have sole and exclusive authority to
commence,  prosecute,  settle, manage, control,  conduct, waive, forgo, release,
discharge,  forgive and otherwise  determine all matters whatsoever with respect
to any Shared Contingent Gain.  Neither Lucent nor NCR shall take, or permit any
member of their respective Groups to take, any action (including  commencing any
claim) that would  interfere with such rights and powers of AT&T. AT&T shall use
its  reasonable  efforts  to notify  each of Lucent and NCR in the event that it
commences an Action with respect to a Shared Contingent Gain;  provided that the
failure to provide  such notice shall not give rise to any rights on the part of
Lucent or NCR against  AT&T or affect any other  provision  of this Section 6.2.
Each of Lucent and NCR acknowledges that AT&T may


<PAGE>

elect  not to  pursue  any  Shared  Contingent  Gain for any  reason  whatsoever
(including a different  assessment  of the merits of any Action,  claim or right
than Lucent or NCR or any  business  reasons  that are in the best  interests of
AT&T or a  member  of the  AT&T  Services  Group,  without  regard  to the  best
interests of any member of the Lucent Group or the NCR Group) and that no member
of the AT&T Group shall have any liability to any Person  (including  any member
of the Lucent Group or the NCR Group) as a result of any such determination.

                  (c) In the event of any  dispute  as to  whether  any claim or
right is a Contingent Gain or whether any Contingent Gain is a Shared Contingent
Gain, an Exclusive AT&T Contingent Gain, an Exclusive Lucent  Contingent Gain or
an Exclusive  NCR  Contingent  Gain,  AT&T may,  but shall not be obligated  to,
commence  prosecution  or  other  assertion  of  such  claim  or  right  pending
resolution  of  such  dispute.  In  the  event  that  AT&T  commences  any  such
prosecution or assertion and, upon resolution of the dispute, a party other than
AT&T is determined hereunder to have the exclusive right to such claim or right,
AT&T shall,  promptly  upon the  request of such other  party,  discontinue  the
prosecution or assertion of such right or claim and transfer the control thereof
to the party so determined to have the right thereto.  In such event,  the party
having the right to such claim or right  will  reimburse  AT&T for all costs and
expenses  (including  allocated costs of in-house counsel and other  personnel),
reasonably  incurred  prior to resolution of such dispute in the  prosecution or
assertion of such claim or right.

                  6.3. EXCLUSIVE CONTINGENT LIABILITIES. (a) Except as otherwise
provided in this Section 6.3,  each  Exclusive  Contingent  Liability or Related
Exclusive   Contingent   Liability  shall   constitute  a  Liability  for  which
indemnification is provided by AT&T, Lucent or NCR, as the case may be, pursuant
to Article V hereof and shall be subject to the  procedures set forth in Article
V with respect thereto.

                  (b)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  except as set forth in  paragraph  (f) of this  Section  6.3, if the
aggregate  Value of all  amounts  paid by  AT&T,  Lucent  or NCR (in each  case,
together  with any  members  of its  respective  Group) in respect of any single
Exclusive Contingent Liability of such Group or any Related Exclusive Contingent
Liabilities of such Group is in excess of $100 million,  each of AT&T, Lucent or
NCR, as the case may be,  shall be entitled  to  reimbursement  from each of the
others  for a share of the  Excess  Portion  in  accordance  with the  following
percentages:

                  (i) in the case of Exclusive AT&T Contingent
Liabilities, AT&T
         shall bear 75  percent of such  Excess  Portion,  Lucent
shall bear 22
         percent of such  Excess  Portion,  and NCR shall bear 3
percent of such
         Excess Portion;

                  (ii) in the case of Exclusive NCR Contingent
Liabilities,  NCR
         shall  bear 50  percent  of such  Excess  Portion,  AT&T
shall bear 37
         percent of such Excess Portion and Lucent shall bear 13
percent of such
         Excess Portion; and

                  (iii) in the case of Exclusive Lucent
Contingent  Liabilities,
         Lucent shall bear 50 percent of such Excess Portion, AT&T shall bear 47
         percent  of such  Excess  Portion  and NCR shall bear 3
percent of such
         Excess Portion.

                  (c) In the event that  after any  payment is made by any party
to any other  party in  accordance  with the  allocation  set  forth in  Section
6.3(b),  any party or any member of such party's  Group  receives any  Insurance
Proceeds,  obtains any  recovery  pursuant to an RBOC  Agreement  or obtains any
other amounts that, in any such case, would reduce the


<PAGE>

Value of all amounts  paid by such party and the members of its Group in respect
of the applicable Exclusive Contingent Liability or Liabilities, such party will
promptly  notify each other party of the receipt of such  Insurance  Proceeds or
recovery of such amount  pursuant to an RBOC  Agreement  or  otherwise  and will
promptly  reimburse  each other  party for the amount of any  payment  that such
first party  would not have been  entitled  to receive if it had  received  such
Insurance  Proceeds or obtained such recovery  pursuant to an RBOC  Agreement or
otherwise  on or  prior to the  date it  received  a  payment  pursuant  to this
Section.  Each such repayment will be accompanied by interest  accruing from the
date of receipt of the original  payment pursuant to this Section to the date of
such repayment at a rate equal to the Prime Rate plus 2% per annum.

                  (d) Each party  agrees to use its  reasonable  best efforts to
advise each other party if it becomes aware of one or more Exclusive  Contingent
Liabilities  that may  result  in a Value  of $100  million  or more;  provided,
however,  that no failure to give any such notice shall  relieve any other party
of any obligation  pursuant to this Agreement.  In the event of any such notice,
or if any other party  otherwise  determines  that any such risk may exist,  the
other  parties will be entitled at their own expense to monitor any such Action.
In any such  event,  the  parties  will enter into a mutually  acceptable  joint
defense  agreement so as to maintain to the extent  reasonably  practicable  the
attorney-client privilege with respect thereto.

                  (e) It shall not be a defense to any  obligation  by any party
to pay any  amount in  respect  of any  Excess  Portion  that such party was not
consulted in the defense thereof,  that such party's views or opinions as to the
conduct of such defense  were not accepted or adopted,  that such party does not
approve of the  quality  or manner of the  defense  thereof or that such  Excess
Portion  was  incurred  by reason of a  settlement  rather than by a judgment or
other  determination  of liability  (even if,  subject to Section  5.5(g),  such
settlement  was  effected  without  the  consent or over the  objection  of such
party).

                  (f)  Neither   AT&T  nor  Lucent  (nor  any  member  of  their
respective  Groups) will be entitled to  reimbursement  pursuant to this Section
6.3 for a share of the Excess  Portion in  respect of any  Exclusive  Contingent
Liability or Related Exclusive  Contingent  Liabilities that would be subject to
sharing with the RBOCs  pursuant to any RBOC  Agreement,  unless the  applicable
party shall have pursued in good faith any recovery to which it or any member of
its Group may be entitled under such RBOC Agreement in respect of such Exclusive
Contingent Liability or Related Exclusive Contingent Liabilities.

                  6.4.  SHARED  CONTINGENT  LIABILITIES.  (a)  As set  forth  in
Section  5.5(c),  AT&T shall  assume the  defense  of, and may seek to settle or
compromise, any Third Party Claim that is a Shared Contingent Liability, and the
costs and  expenses  (including  allocated  costs of in-house  counsel and other
personnel)  thereof  shall be included in the  calculation  of the amount of the
applicable  Shared   Contingent   Liability  in  determining  the  reimbursement
obligations of the other parties with respect  thereto  pursuant to this Section
6.4.

                  (b) Each of AT&T,  Lucent and NCR shall be responsible for its
Shared Percentage of any Shared Contingent Liability.  It shall not be a defense
to any  obligation  by any party to pay any  amount  in  respect  of any  Shared
Contingent  Liability that such party was not consulted in the defense  thereof,
that such  party's  views or opinions as to the conduct of such defense were not
accepted or adopted, that such party does not approve of the


<PAGE>

quality  or  manner  of the  defense  thereof  or that  such  Shared  Contingent
Liability  was incurred by reason of a  settlement  rather than by a judgment or
other  determination  of liability  (even if,  subject to Section  5.5(g),  such
settlement  was  effected  without  the  consent or over the  objection  of such
party).

                  6.5.  PAYMENTS.  (a) Any amount  owed in respect of any Shared
Contingent  Liabilities  (including   reimbursement  for  the  cost  or  expense
(including  allocated costs of in-house  counsel and other personnel) of defense
of (i) any Third Party Claim that is a Shared  Contingent  Liability),  (ii) any
Excess  Portion  of any  Exclusive  Contingent  Liabilities  or of  any  Related
Exclusive  Contingent  Liabilities or (iii) any Shared Contingent Gains pursuant
to this Article VI shall be remitted  promptly  after the party entitled to such
amount provides an invoice  (including  reasonable  supporting  information with
respect thereto) to the party owing such amount.

                  (b) In the case of any Shared Contingent Liability, AT&T shall
be  entitled  to  reimbursement  from  Lucent  and  NCR in  advance  of a  final
determination  of any Action for amounts  paid in respect of costs and  expenses
(including  allocated  costs of in-house  counsel and other  personnel)  related
thereto,  from time to time as such costs and expenses are incurred. In the case
of any Shared  Contingent Gain, AT&T shall be entitled to retain from the amount
of the Shared  Contingent Gain otherwise payable to Lucent and NCR, Lucent's and
NCR's  respective  Shared  Percentage  of  the  costs  and  expenses  (including
allocated costs of in-house  counsel and other personnel) paid or incurred by or
on  behalf of any  member of the AT&T  Services  Group in  connection  with such
Shared Contingent Gain.

                  (c) Any amounts billed and properly payable in accordance with
this  Article  VI that are not  paid  within  30 days of such  bill  shall  bear
interest at the Prime Rate plus 2% per annum.


                  6.6. PROCEDURES TO DETERMINE STATUS OF
CONTINGENT LIABILITY OR
CONTINGENT  GAIN. (a) With respect to the Actions set forth on
Schedule 6.6, and
with  respect to any other  matters not set forth on Schedules
6.1(e),  6.1(f),
6.1(g) or 6.1(n)  (regardless of whether such matters are currently  pending but
not set forth on such  Schedules  or are  asserted  or filed  hereafter),  AT&T,
Lucent  and NCR will form the  Contingent  Claim  Committee  for the  purpose of
resolving whether:


                  (i) any claim or right is a Contingent Gain;

                  (ii) any Contingent Gain is a Shared Contingent
Gain, an
         Exclusive AT&T Contingent Gain, an Exclusive Lucent
Contingent Gain or
         an Exclusive NCR Contingent Gain;

                  (iii) any Liability is a Contingent Liability;

                  (iv) any Contingent Liability is a Shared
Contingent
         Liability, an Exclusive AT&T Contingent Liability, an
Exclusive Lucent
         Contingent Liability or an Exclusive NCR Contingent
Liability; or

                  (v) any Exclusive Contingent Liabilities
constitute Related
         Exclusive Contingent Liabilities.

                  (b) Any of the  parties  may  refer any  potential  Contingent
Gains or Contingent Liabilities to the Contingent Claim Committee for resolution
as described in Section


<PAGE>

6.6(a) and the Contingent Claim Committee's  determination  (which shall be made
within 30 days of such referral),  if unanimous,  shall be binding on all of the
parties  and their  respective  successors  and  assigns.  In the event that the
Contingent  Claim  Committee  cannot reach a unanimous  determination  as to the
nature or status of any such Contingent  Liabilities or Contingent  Gains within
30 days  after  such  referral,  the issue  will be  submitted  for  arbitration
pursuant to the procedures set forth in Article IX of this Agreement, subject to
Section 9.8. The outcome of the  arbitration  pursuant to Article IX (subject to
Section  9.8) shall be final and  binding on all  parties  and their  respective
successors and assigns.



                  (c) In  resolving,  with  respect  to any  Action set forth on
Schedule  6.6 or any other  matter not set forth in  Schedules  6.1(e),  6.1(f),
6.1(g) and 6.1(n),  whether (i) any Contingent Gain is a Shared Contingent Gain,
an Exclusive AT&T  Contingent  Gain, an Exclusive  Lucent  Contingent Gain or an
Exclusive  NCR  Contingent  Gain or (ii) any  Contingent  Liability  is a Shared
Contingent  Liability,  an Exclusive  AT&T  Contingent  Liability,  an Exclusive
Lucent  Contingent  Liability  or an Exclusive  NCR  Contingent  Liability,  the
categorization  of Contingent  Claims and  Contingent  Liabilities  reflected in
Schedules  6.1(e),  6.1(f),  6.1(g) and 6.1(n) shall be considered and used as a
precedential guide.




                  (d) At any  time or from  time to time  prior  to the  Closing
Date, the Solicitor General of AT&T, following consultation with representatives
of each of Lucent and NCR, may amend or supplement any of
Schedules  6.1(e),
6.1(f), 6.1(g) and 6.1(n). Without limiting the foregoing,  prior to the Closing
Date, the parties will continue to review Schedule 6.6 to determine  whether any
matter set forth therein will be reassigned to one of Schedules
6.1(e),  6.1(f),
6.1(g) or 6.1(n).

                  6.7.  CERTAIN  CASE  ALLOCATION  MATTERS.  (a)  Lucent and NCR
acknowledge  that  Third  Party  Claims  may be  asserted  in respect of alleged
repetitive stress injuries in a single Action (including a group of consolidated
Actions) that involve both computer keyboards or related equipment  manufactured
in the conduct of the NCR Business  (which  would  constitute  an Exclusive  NCR
Contingent  Liability) and computer keyboards or related equipment  manufactured
in the  conduct  of  the  discontinued  computer  operations  of  AT&T  and  its
Affiliates,  other than any member of the NCR Group (which would  constitute  an
Exclusive  Lucent  Contingent  Liability).  Lucent  and NCR  agree to use  their
reasonable  best efforts to share  responsibility  (including  for all costs and
expenses  (including  allocated costs of in-house counsel and other  personnel))
for any such Third Party Claims or Actions,  notwithstanding  any  allocation of
such Actions set forth in Schedules 6.1(e),  6.1(f), 6.1(g) and 6.1(n), so that,
to the maximum  extent  reasonably  practicable,  the parties will have the same
rights and  obligations  (including  pursuant to Article V hereof) as would have
been  applicable if such matters had been commenced as separate  Actions.  Third
Party   Claims  with  respect  to  computer   keyboards  or  related   equipment
manufactured  in the  conduct  of the NCR  Business  shall  not be  deemed to be
Related Exclusive Contingent Liabilities with Third Party Claims with respect to
any computer  keyboards or related equipment  manufactured in the conduct of the
discontinued  computer  operations  of AT&T and its  Affiliates  (other than any
member of the NCR Group).

                  (b) The  parties  agree  that if any  Action  not set forth on
Schedule 6.1(e),  6.1(f), 6.1(g) or 6.1(n) involves separate and distinct claims
that, if not joined in a single  Action,  would  constitute  separate  Exclusive
Contingent  Liabilities of two or more parties,  they will use their  reasonable
best  efforts  to  segregate  such  separate  and  distinct  claims  so that the
Liabilities  associated  with each such claim  (including all costs and expenses
(including  allocated costs of in-house counsel and other  personnel))  shall be
treated as Exclusive Contingent Liabilities of the appropriate party and so that
each party shall have the rights


<PAGE>

and obligations with respect to each such claim (including pursuant to Article V
hereof) as would have been applicable had such claims been commenced as separate
Actions. Notwithstanding the foregoing provisions, this Section 6.7(b) shall not
apply to any  separate  and  distinct  claim that is de minimis or  frivolous in
nature.


                  (c) The parties  agree that  notwithstanding  anything in this
Agreement to the contrary,  all  Liabilities  arising out of,  resulting from or
relating  to  the  Action  commenced  by  Bell  Atlantic   Corporation  and  DSC
Communications Corporation against AT&T and Lucent in the United States District
Court for the Eastern  District of Texas on February 14, 1996, (i) to the extent
relating to Caller ID services,  shall be Exclusive AT&T Contingent  Liabilities
and (ii) to the extent  relating  to  telecommunications  equipment,  systems or
software,  shall be Exclusive Lucent  Contingent  Liabilities;  provided however
that  each of the  parties  shall  bear its own costs  and  expenses  (including
allocated costs of in-house  counsel and other  personnel) of defending any such
claims,   including  any  such  costs  and  expenses  of  any  related  document
productions.

                                   ARTICLE VII
                  INTERIM OPERATIONS AND CERTAIN OTHER MATTERS

                  7.1. INSURANCE MATTERS.  (a) Lucent agrees that it will pay to
AT&T $1 million per month  (prorated on a daily basis for any partial  month) in
respect of the period from the date hereof  until the  Distribution  Date,  such
amount to be payable in arrears by the 10th day of the next succeeding month, in
respect of Insurance  Policies under which Lucent will continue to have coverage
following  the date hereof.  AT&T and Lucent agree to cooperate in good faith to
provide for an orderly  transition  of insurance  coverage  from the date hereof
through the  Distribution  Date and for the treatment of any Insurance  Policies
that will remain in effect  following  the Closing Date on a mutually  agreeable
basis.  In no event shall AT&T,  any other  member of the AT&T Group or any AT&T
Indemnitee or NCR  Indemnitee  have  liability or  obligation  whatsoever to any
member of the  Lucent  Group in the  event  that any  Insurance  Policy or other
contract or policy of insurance  shall be terminated or otherwise cease to be in
effect for any reason, shall be unavailable or inadequate to cover any Liability
of any member of the  Lucent  Group for any  reason  whatsoever  or shall not be
renewed or extended beyond the current expiration date.

                  (b) As  promptly  as  practicable,  each  party  shall use its
reasonable  best efforts to consummate  the  transactions  set forth on Schedule
7.1(b) with respect to American Ridge and its Subsidiaries.

                  (c) (i) Except in the case of the Ridge  Lucent  Policies  and
except as otherwise provided in any Ancillary  Agreement,  the parties intend by
this  Agreement  that  Lucent  and each  other  member  of the  Lucent  Group be
successors-in-interest  to all rights  that any  member of the Lucent  Group may
have as of the Closing Date as a subsidiary,  affiliate,  division or department
of AT&T prior to the Closing Date under any policy of  insurance  issued to AT&T
by any insurance carrier  unaffiliated with AT&T or under any agreements related
to such policies executed and delivered prior to the Closing Date, including any
rights such  member of the Lucent  Group may have,  as an insured or  additional
named insured, subsidiary, affiliate, division or department, to avail itself of
any such policy of insurance or any such agreements  related to such policies as
in effect prior to the Closing Date.  At the request of Lucent,  AT&T shall take
all reasonable  steps,  including the execution and delivery of any instruments,
to effect the foregoing; provided however that AT&T


<PAGE>

shall not be required to pay any amounts, waive any rights or
incur any
Liabilities in connection therewith.

                  (ii)  Except  in the case of the  Ridge  Lucent  Policies  and
except as otherwise  contemplated by any Ancillary Agreement,  after the Closing
Date, none of AT&T or Lucent or any member of their respective
Groups  shall,
without the  consent of the other,  provide any such  insurance  carrier  with a
release,  or  amend,  modify  or waive  any  rights  under  any such  policy  or
agreement,  if such release,  amendment,  modification or waiver would adversely
affect  any  rights  or  potential  rights  of any  member  of the  other  Group
thereunder;  provided  however  that the  foregoing  shall not (A)  preclude any
member of any Group  from  presenting  any claim or from  exhausting  any policy
limit, (B) require any member of any Group to pay any premium or other amount or
to incur any Liability,  or (C) require any member of any Group to renew, extend
or  continue  any  policy in  force.  Each of Lucent  and AT&T will  share  such
information  as is  reasonably  necessary in order to permit the other to manage
and conduct its insurance matters in an orderly fashion.

                  (d) This  Agreement  shall not be  considered  as an attempted
assignment  of any policy of insurance  or as a contract of insurance  and shall
not be construed to waive any right or remedy of any member of the AT&T Group in
respect of any Insurance Policy or any other contract or policy of insurance.

                  (e) Lucent does  hereby,  for itself and each other  member of
the Lucent Group, their respective Affiliates (other than any member of the AT&T
Group),  successors  and  assigns,  and all  Persons  who at any time  have been
shareholders,  directors,  officers,  agents or  employees  of any member of the
Lucent Group (in each case, in their respective  capacities as such), agree that
all Ridge Lucent Policies will automatically be terminated in all respects as of
the Distribution Date (without any further action by any Person) and, as of such
date,  remise,  release and forever  discharge each AT&T Indemnitee and each NCR
Indemnitee  with respect  thereto.  Lucent agrees to indemnify,  defend and hold
harmless  each  member  of the AT&T  Group  and  each  AT&T  Indemnitee  and NCR
Indemnitee if any Person shall claim that it is entitled to any payment from any
of the foregoing in respect of any Ridge Lucent Policy.  At the request of AT&T,
Lucent will take,  or cause to be taken,  all action  necessary to terminate any
Ridge  Lucent  Policies  and all  Liabilities  of any  member of the AT&T  Group
thereunder, effective as of the Distribution Date.

                  (f) Lucent does  hereby,  for itself and each other  member of
the Lucent Group,  agree that no member of the AT&T Group or any AT&T Indemnitee
or NCR  Indemnitee  shall  have any  Liability  whatsoever  as a  result  of the
insurance  policies and practices of AT&T and its Affiliates as in effect at any
time prior to the Closing  Date,  including as a result of the level or scope of
any such insurance, the creditworthiness of any insurance carrier, the terms and
conditions  of any  policy,  the  adequacy  or  timeliness  of any notice to any
insurance carrier with respect to any claim or potential claim or otherwise.

                  (g) Nothing in this Agreement  shall be deemed to restrict any
member of the Lucent Group from acquiring at its own expense any other insurance
policy in respect of any Liabilities or covering any period.

                  7.2.   COLLECTION   OF   ACCOUNTS   RECEIVABLE.   (a)   Lucent
acknowledges  on behalf of itself and each other member of the Lucent Group that
it is aware that the Retained  Receivables  are Excluded Assets and that certain
Persons that are account debtors with respect to accounts  receivables  included
in the Lucent  Assets (or that in the future may otherwise  become  payable to a
member of the Lucent Group) are also account debtors with


<PAGE>

respect to the Retained Receivables.  Lucent agrees that from and after the date
hereof and prior to December 31, 1997, unless otherwise specifically directed by
AT&T,  Lucent,  as agent for AT&T, will take all  commercially  reasonable steps
consistent with the Lucent  Business's  current practices to service and collect
the  Retained  Receivables.  AT&T and Lucent  will  cooperate  to  establish  as
promptly as practicable mutually acceptable operational procedures. In addition,
Lucent will use all  reasonable  best efforts to satisfy any  conditions  to the
payment of any  Retained  Receivables  and to  fulfill  all  obligations  to the
applicable  account  debtors  related to such  Retained  Receivables;  provided,
however  that if,  in order to  collect  any  Retained  Receivables,  Lucent  is
required to engage a collection  agency or to institute legal proceedings or any
other  Action  it  shall  be  entitled  to  be  reimbursed  for  its  reasonable
out-of-pocket  costs  and  expenses  incurred  in  connection  therewith.  After
December 31, 1997,  the parties will negotiate in good faith with respect to the
final disposition of any then outstanding Retained Receivables.

                  (b) Any  payment  made by an  account  debtor to Lucent or any
member of the Lucent  Group  with  respect  to an  account  receivable  shall be
applied to the Retained  Receivables  (and paid over to AT&T in accordance  with
this  Section  7.2)  before  they are  applied to any other  account  receivable
whenever arising for such account debtor  (regardless of the respective dates of
such  accounts  receivable  or of any  specific  notation to the contrary by the
applicable account debtor),  unless the applicable account debtor specifies that
such payment shall be applied to another  account payable of such account debtor
that (i) arose from an order placed after the date of this Agreement and (ii) is
both due and paid prior to the first due date of any Retained  Receivable or any
other account receivable of such account debtor.

                  (c) Each of AT&T and  Lucent  shall  deliver to the other such
schedules and other information with respect to the Retained Receivables and the
accounts  receivables  included  in the Lucent  Assets as each shall  reasonably
request  from time to time in order to permit such  parties to  reconcile  their
respective  records and to monitor the  collection  of all  accounts  receivable
(whether Lucent Assets or Retained  Receivables).  Each of Lucent and AT&T shall
afford the other  reasonable  access to its books and  records  relating  to any
accounts receivable.  Without limiting the foregoing,  Lucent shall at all times
maintain  the  ability  to  provide  to AT&T  promptly  upon  request a true and
complete schedule of all Retained Receivables due and owing as of the end of the
prior month.

                  (d) By the  15th  day of each  month  (or if such day is not a
business day, by the next business day), Lucent hereby irrevocably agrees to pay
over, or cause to be paid over, in  immediately  available  funds to AT&T, at no
cost or charge to AT&T or any of its  Affiliates  (other  than any member of the
Lucent  Group),  any and all amounts which were received (or deemed  received in
accordance with Section  7.2(b)) during the  immediately  preceding month by any
member of the  Lucent  Group in respect of the  Retained  Receivables.  Any such
amounts  not paid over to AT&T by the date  specified  in the first  sentence of
this Section 7.2(d) shall bear interest at the Prime Rate plus 2% per annum.

                  (e) Nothing in this Agreement or any Ancillary Agreement shall
be  construed  to grant to any  member of the Lucent  Group any right,  title or
interest in any Retained Receivable and no member of the Lucent Group shall have
any right or power to, and no member of the Lucent Group shall,  grant or suffer
to exist  any  right of set off,  lien or any  other  Security  Interest  in any
Retained  Receivables  or proceeds  thereof.  Lucent  will not,  and it will not
permit any member of the Lucent Group to, extend or otherwise  change the amount
or other terms of payment of any Retained  Receivable,  unless Lucent shall have
paid to AT&T an amount  equal to the full  amount of such  Retained  Receivable.
Lucent


<PAGE>

hereby irrevocably and  unconditionally  agrees that it shall not assert (and it
shall not permit any member of the Lucent Group to assert) any offsets,  claims,
counterclaims  or  defenses  in  respect  of  the  Retained  Receivables  or its
obligations to pay over any such Retained Receivables to AT&T hereunder (whether
existing on the date hereof or arising  hereafter and whether or not relating to
the  transactions  contemplated  by this Agreement,  any Ancillary  Agreement or
otherwise).

                  (f) AT&T shall  retain the right to collect or seek to collect
in such manner as it may in its sole discretion  determine all or any portion of
the Retained Receivables.

                  (g) Lucent  hereby  represents  and warrants to AT&T that each
Retained  Receivable  constitutes a legal,  valid and binding  obligation of the
applicable account debtor enforceable  against such account debtor in accordance
with its respective terms,  except as the enforceability  thereof may be limited
by  bankruptcy,  insolvency,  moratorium  and other  similar laws  affecting the
enforcement of creditors' rights  generally,  and is not subject to any Security
Interest or any other lien, claim, defense or right of set-off.

                  (h) On or prior to February 15, 1996,  Lucent shall deliver to
AT&T a true and correct list of each of the Retained Receivables in such form as
AT&T shall reasonably  request.  Such list shall specify the face amount of each
Retained Receivable and a summary of the total Retained  Receivables,  including
the allocations  thereof among the Lucent business units, the applicable  credit
loss  reserve  thereon  and such  other  information  as AT&T  shall  reasonably
request.

                  7.3. OPERATING  FINANCIAL  LIABILITIES.  (a) As between Lucent
and AT&T, Lucent hereby irrevocably assumes and agrees to pay, perform,  satisfy
and discharge all liabilities, obligations,  contingencies and other Liabilities
under,  or otherwise  relating to, arising out of or resulting  from, all Lucent
OFL's.  For  purposes of this  Agreement,  the term "Lucent OFL" means the OFL's
listed or  described on Schedule  7.3(a) and any other OFL's that are  primarily
related  to,  arise out of or result  from any Lucent  Asset,  Lucent  Liability
(including  any  Lucent  Contract)  or Lucent  Business  or that were  otherwise
entered into in connection with the conduct of the Lucent Business.  The parties
hereto  acknowledge  that there may be OFL's that are Lucent  OFL's that are not
set forth or described on such Schedule  7.3(a),  either  because such OFL's are
entered  into  after the date  hereof or because  such OFL's were  inadvertently
excluded from such Schedule. As a result, the parties agree to cooperate in good
faith  to  supplement  Schedule  7.3(a)  as  any  additional  Lucent  OFL's  are
identified.  In the event that any OFL is so added to such Schedule 7.3(a), AT&T
will  retroactively  bill  Lucent in  accordance  with this  Section 7.3 for any
amount payable by any member of the AT&T Group on or after the date hereof,  and
AT&T will  retroactively  credit Lucent in accordance  with this Section 7.3 for
any amount  paid to any  member of the AT&T  Group on or after the date  hereof,
together in each case with  interest  thereon  from the date of payment by or to
any such member of the AT&T Group, as the case may be, to the date of settlement
of such bill or credit,  at the AT&T CP Rate that would have been  applicable if
such Lucent OFL had  originally  been  included on Schedule  7.3(a),  subject to
increase pursuant to Section 7.3(c)(ii).

                  (b) (i) AT&T  may,  from time to time,  set forth on  Schedule
7.3(a)  whether  any  Lucent  OFL's  are to be paid,  performed,  satisfied  and
discharged  directly by Lucent.  AT&T may at any time or from time to time on at
least 30 days' written notice to Lucent,  modify such Schedule  7.3(a) to change
whether  any Lucent  OFL shall  thereafter  be paid,  performed,  satisfied  and
discharged  directly  by Lucent or by AT&T.  AT&T  shall,  in the absence of any
default by Lucent under this Section 7.3, pay, or cause to be paid, all other


<PAGE>

Lucent  OFL's,  and  Lucent  agrees  to  reimburse  AT&T  for such  payments  in
accordance with the terms of this Section 7.3. If Lucent is in default of any of
its obligations under this Section 7.3, AT&T shall no longer be required to pay,
or cause to be paid,  any Lucent OFL's and Lucent shall be required  directly to
pay, perform, satisfy and discharge such Lucent OFL's.

                  (ii) In the  event  that  payments  are made by a third  party
under any Lucent  OFL,  if Lucent is not in  default  of any of its  obligations
under this  Section  7.3,  (A) if any such  payment is made to any member of the
Lucent  Group,  such  member of the Lucent  Group will be entitled to retain any
such payments  received by it, and (B) if any such payment is made to any member
of the AT&T Group,  such  member of the AT&T Group  shall,  at AT&T's  election,
either remit any such amounts it receives to Lucent or net such amounts  against
payments  AT&T is then  required  to make under any other  Lucent OFL or against
payments then owed (whether or not then due) to AT&T by Lucent hereunder.

                  (iii) In the event  that  payments  are made by a third  party
under any Lucent  OFL, if Lucent is in default of any of its  obligations  under
this  Section  7.3,  (A) if any such payment is made to any member of the Lucent
Group,  Lucent shall  promptly  remit any such payments to AT&T,  and (B) if any
such  payment is made to any member of the AT&T  Group,  AT&T shall be  entitled
(but not  required)  to apply any such  payments to satisfy,  any such breach by
Lucent,  either,  at AT&T's option, by netting amounts then owed (whether or not
then due) to AT&T by Lucent  hereunder or by paying over such monies in order to
satisfy any obligation in respect of any Lucent OFL.

                  (iv) In the event that  payment or receipt of  commodities  or
other  property is called for under any Lucent OFL,  the parties  will  mutually
agree upon  reasonable  then  current  market-based  valuations  to convert such
payment or receipt into dollars,  unless  Lucent  determines to make delivery or
take receipt under the Lucent OFL in commodities or property.

                  (c)  (i)  AT&T  shall  issue a  statement  to  Lucent  for the
payments  due from or payable to Lucent  pursuant to this Section 7.3 in respect
of any  month by the  tenth  business  day of the  following  month.  Each  such
statement shall set forth the AT&T CP Rate for the immediately  preceding month.
Interest  will accrue and be payable by Lucent on all  amounts  due  pursuant to
this  Section  7.3 in respect of Lucent  OFL's at the AT&T CP Rate in effect for
the month immediately  preceding the month in which the statement is issued from
the date of payment of any such amount by any member of the AT&T Group under any
Lucent  OFL to the date of  payment  therefor  to AT&T by  Lucent.  In the event
payments  are due by AT&T to  Lucent  under  this  Section  7.3,  AT&T  will pay
interest at the AT&T CP Rate in effect for the month  immediately  preceding the
month in which the statement is issued from the date of receipt by AT&T under an
Lucent OFL to the date of payment by AT&T.  All payments  under this Section 7.3
shall be in same day funds.

                  (ii) Lucent  agrees to pay AT&T any amounts due  (including in
respect of  interest)  within 10 days of receipt  of each  statement.  AT&T will
remit to Lucent any payments  (including in respect of interest) received by any
member of the AT&T  Group  under any  Lucent  OFL (to the  extent  not netted in
accordance  with Section  7.3(b))  within 10 days of the date of statement.  Any
amounts  not paid when due shall  bear  interest  at the Prime  Rate plus 2% per
annum in lieu of the AT&T CP Rate.

                  (d) (i) Lucent may prepay (or effect the early termination) of
any Lucent OFL's  provided that no additional  Liability is thereby  created for
any member of the AT&T


<PAGE>

Group other than any  Liabilities  that are fully  discharged  and  satisfied by
Lucent simultaneously with such prepayment or early termination.

                  (ii) Without  AT&T's  written  consent,  Lucent will not enter
into or permit any  amendment,  modification  or waiver of any  provision of any
Lucent  OFL;  provided  that  AT&T  agrees  that it  will  consent  to any  such
amendments,  modifications or waivers that do not create additional  obligations
or Liabilities  for any member of the AT&T Group or otherwise  adversely  affect
any member of the AT&T Group.

                  (iii) Each party will give prompt notice to the other party of
any default by it or, if it becomes aware thereof,  by any third party under any
Lucent OFL.

                  (iv) In the event that Lucent  makes any payment in respect of
an Lucent OFL,  Lucent will be subrogated to all rights of AT&T or any member of
the AT&T Group with  respect  to such  Lucent  OFL,  including  with  respect to
collateral, to the extent of such payment.

                  7.4.  CERTAIN  BUSINESS  MATTERS.  (a) No  member of any Group
shall  have  any  duty to  refrain  from (i)  engaging  in the  same or  similar
activities  or lines of  business as any member of any other  Group,  (ii) doing
business with any potential or actual  supplier or customer of any member of any
other Group,  or (iii)  engaging in, or refraining  from,  any other  activities
whatsoever  relating to any of the potential or actual suppliers or customers of
any member of any other Group.

                  (b) Each of AT&T,  Lucent  and NCR is aware  that from time to
time certain business  opportunities  may arise which more than one Group may be
financially able to undertake,  and which are, from their nature, in the line of
more than one Group's  business and are of practical  advantage to more than one
Group.  In  connection  therewith,  the parties  agree that if prior to (but not
following) the Distribution  Date, any of AT&T, Lucent or NCR acquires knowledge
of an  opportunity  that meets the foregoing  standard with respect to more than
one Group,  none of AT&T,  Lucent or NCR shall have any duty to  communicate  or
offer such  opportunity  to any of the  others  and may  pursue or acquire  such
opportunity for itself,  or direct such opportunity to any other Person,  unless
(i) such opportunity relates primarily to the AT&T Services Business, the Lucent
Business or the NCR Business, in which case the party that acquires knowledge of
such opportunity  shall use its reasonable best efforts to communicate and offer
such opportunity to AT&T, Lucent or NCR, respectively,  or (ii) such opportunity
relates  both to the AT&T  Services  Business  and the Lucent  Business  but not
primarily to either one, in which case such party shall use its reasonable  best
efforts to communicate and offer such opportunity to Lucent. Notwithstanding the
foregoing,  no party  shall be  required  to so  communicate  or offer  any such
opportunity  if it would  result in the breach of any  contract or  agreement or
violate any applicable law, rule or regulation of any Governmental Authority, no
party shall have any  obligation  to finance  (or  provide any other  assistance
whatsoever) to any other party in connection with any such  opportunity.  In the
event the foregoing clause (i) or (ii) is applicable,  no party,  other than the
party to whom the  opportunity  must be offered in accordance with such clauses,
shall pursue or acquire such opportunity for itself,  or direct such opportunity
to any other Person,  unless the party to whom the opportunity is required to be
offered does not within a reasonable period of time begin to pursue, or does not
thereafter continue to pursue, such opportunity diligently and in good faith.

                  7.5. LATE PAYMENTS. Except as expressly provided
to the
contrary in this Agreement or in any Ancillary Agreement, any
amount not paid
when due pursuant to this


<PAGE>

Agreement  or any  Ancillary  Agreement  (and any  amounts  billed or  otherwise
invoiced or demanded  and  properly  payable that are not paid within 30 days of
such bill,  invoice or other demand)  shall accrue  interest at a rate per annum
equal to the Prime Rate plus 2%.

                  7.6. TRANSITIONAL BELL LABS SERVICES.  Prior to, on, and after
the Closing Date, AT&T and each member of the AT&T Group,  shall have the right,
to obtain from Lucent or any member of the Lucent  Group,  the  Identified  Bell
Labs  Services,  and such  other  services  that are  provided  by  Lucent  Bell
Laboratories that AT&T may from time to time reasonably  determine are necessary
to assure a smooth and orderly  transition of the businesses,  in each case on a
commercially  reasonable  basis.  Each of the parties shall use their reasonable
best efforts to identify and document any such  additional  services on or prior
to the Closing Date; provided,  however, that whether or not identified prior to
the Closing Date,  prior to, on, and after the Closing Date,  each member of the
AT&T  Group  shall  continue  to have the  right to  obtain  such  services,  on
commercially reasonable terms, as contemplated by this Section 7.6.

                                  ARTICLE VIII
                    EXCHANGE OF INFORMATION; CONFIDENTIALITY

                  8.1. AGREEMENT FOR EXCHANGE OF INFORMATION; ARCHIVES. (a) Each
of AT&T, Lucent and NCR, on behalf of its respective  Group,  agrees to provide,
or cause to be provided,  to each other  Group,  at any time before or after the
Distribution  Date, as soon as  reasonably  practicable  after  written  request
therefor,  any  Information  in the  possession  or under  the  control  of such
respective  Group which the requesting party reasonably needs (i) to comply with
reporting,  disclosure,  filing or other requirements  imposed on the requesting
party  (including  under  applicable  securities or tax laws) by a  Governmental
Authority having  jurisdiction  over the requesting  party,  (ii) for use in any
other judicial, regulatory,  administrative, tax or other proceeding or in order
to satisfy  audit,  accounting,  claims,  regulatory,  litigation,  tax or other
similar  requirements,  or  (iii) to  comply  with its  obligations  under  this
Agreement, any Ancillary Agreement or any Lucent OFL; provided, however, that in
the event that any party determines that any such provision of Information could
be  commercially  detrimental,  violate  any  law or  agreement,  or  waive  any
attorney-client  privilege,  the parties shall take all  reasonable  measures to
permit the  compliance  with such  obligations  in a manner that avoids any such
harm or consequence.

                  (b) After the Closing  Date,  Lucent shall have access  during
regular  business  hours (as in effect from time to time) to the  documents  and
objects of historic  significance  that relate to the Lucent  Business  that are
located in the AT&T Archives  located at 5 Reineman  Road,  Warren,  New Jersey.
Lucent may obtain copies (but not originals) of documents for bona fide business
purposes  and may  obtain  objects  for  exhibition  purposes  for  commercially
reasonable periods of time if required for bona fide business purposes, provided
that  Lucent  shall cause any such  objects to be returned  promptly in the same
condition  in which they were  delivered  to Lucent and Lucent shall comply with
any  rules,  procedures  or other  requirements,  and  shall be  subject  to any
restrictions  (including prohibitions on removal of specified objects), that are
then  applicable to AT&T.  Lucent shall pay $125 per hour for archives  research
services  (subject to increase from time to time to reflect rates then in effect
for AT&T  generally).  Nothing  herein shall be deemed to restrict the access of
any member of the AT&T Group or the NCR Group to any such  documents  or objects
or to impose any liability on any member of the AT&T Group if any such documents
or objects are not maintained or preserved by AT&T.


<PAGE>

                  (c) After the date hereof, (i) Lucent shall maintain in effect
at its own  cost  and  expense  adequate  systems  and  controls  to the  extent
necessary  to enable the members of the AT&T Group to satisfy  their  respective
reporting,  accounting,  audit  and other  obligations,  and (ii)  Lucent  shall
provide, or cause to be provided, to AT&T in such form as AT&T shall request, at
no  charge  to AT&T,  all  financial  and  other  data and  information  as AT&T
determines  necessary or advisable in order to prepare AT&T financial statements
and reports or filings with any Governmental Authority.

                  8.2.  OWNERSHIP OF INFORMATION.  Any Information  owned by one
Group that is provided to a  requesting  party  pursuant to Section 8.1 shall be
deemed to remain the property of the providing  party.  Unless  specifically set
forth herein, nothing contained in this Agreement shall be construed as granting
or conferring rights of license or otherwise in any such Information.

                  8.3.  COMPENSATION  FOR  PROVIDING   INFORMATION.   The  party
requesting  such  Information  agrees  to  reimburse  the  other  party  for the
reasonable  costs, if any, of creating,  gathering and copying such Information,
to the extent that such costs are  incurred  for the  benefit of the  requesting
party.  Except  as may be  otherwise  specifically  provided  elsewhere  in this
Agreement or in any other  agreement  between the  parties,  such costs shall be
computed in  accordance  with the providing  party's  standard  methodology  and
procedures.

                  8.4. RECORD RETENTION.  To facilitate the possible exchange of
Information pursuant to this Article VIII and other provisions of this Agreement
after the  Distribution  Date,  the parties agree to use their  reasonable  best
efforts to retain all Information in their  respective  possession or control on
the  Distribution  Date in accordance  with the policies of AT&T as in effect on
the Closing Date. No party will destroy,  or permit any of its  Subsidiaries  to
destroy,  any  Information  which the  other  party may have the right to obtain
pursuant to this  Agreement  prior to the third  anniversary  of the date hereof
without first using its reasonable best efforts to notify the other party of the
proposed  destruction  and  giving  the  other  party  the  opportunity  to take
possession of such information  prior to such  destruction;  provided,  however,
that in the  case of any  Information  relating  to  Taxes  or to  Environmental
Liabilities,  such period shall be extended to the  expiration of the applicable
statute of limitations (giving effect to any extensions thereof).

                  8.5.  LIMITATION  OF  LIABILITY.   No  party  shall  have  any
liability  to any other  party in the event that any  Information  exchanged  or
provided  pursuant to this Agreement which is an estimate or forecast,  or which
is based on an estimate or forecast,  is found to be inaccurate,  in the absence
of willful  misconduct by the party providing such  Information.  No party shall
have any  liability to any other party if any  Information  is  destroyed  after
reasonable  best efforts by such party to comply with the  provisions of Section
8.4.

                  8.6. OTHER  AGREEMENTS  PROVIDING FOR EXCHANGE OF INFORMATION.
The rights and  obligations  granted  under this Article VIII are subject to any
specific  limitations,  qualifications or additional  provisions on the sharing,
exchange or  confidential  treatment of  Information  set forth in any Ancillary
Agreement.

                  8.7. PRODUCTION OF WITNESSES;  RECORDS; COOPERATION. (a) After
the  Closing  Date,  except  in the case of an  adversarial  Action by one party
against another party (which shall be governed by such discovery rules as may be
applicable  under  Article IX or  otherwise),  each party  hereto  shall use its
reasonable  best efforts to make  available  to each other  party,  upon written
request, the former, current and future directors,  officers,  employees,  other
personnel and agents of the members of its respective Group as witnesses and


<PAGE>

any books,  records or other documents  within its control or which it otherwise
has the ability to make  available,  to the extent that any such person  (giving
consideration to business demands of such directors,  officers, employees, other
personnel and agents) or books,  records or other  documents  may  reasonably be
required in connection  with any Action in which the  requesting  party may from
time to time be  involved,  regardless  of whether  such Action is a matter with
respect to which  indemnification may be sought hereunder.  The requesting party
shall bear all costs and expenses (including allocated costs of in-house counsel
and other personnel) in connection therewith.

                  (b) If an  Indemnifying  Party or AT&T chooses to defend or to
seek to compromise  or settle any Third Party Claim,  or if any party chooses to
prosecute or otherwise evaluate or to pursue any Contingent Gain or any recovery
in respect of any RBOC Agreement, the other parties shall make available to such
Indemnifying  Party,  AT&T or such other party, as the case may be, upon written
request, the former, current and future directors,  officers,  employees,  other
personnel and agents of the members of its respective Group as witnesses and any
books,  records or other documents  within its control or which it otherwise has
the  ability to make  available,  to the  extent  that any such  person  (giving
consideration to business demands of such directors,  officers, employees, other
personnel and agents) or books,  records or other  documents  may  reasonably be
required in connection  with such defense,  settlement  or  compromise,  or such
prosecution,  evaluation  or  pursuit,  as the case may be, and shall  otherwise
cooperate  in such  defense,  settlement  or  compromise,  or such  prosecution,
evaluation or pursuit, as the case may be.

                  (c)  Without   limiting  the  foregoing,   the  parties  shall
cooperate  and consult to the extent  reasonably  necessary  with respect to any
Actions, Contingent Liabilities and Contingent Gains.

                  (d) Without  limiting any provision of this  Section,  each of
the parties  agrees to  cooperate,  and to cause each  member of its  respective
Group to  cooperate,  with each  other in the  defense  of any  infringement  or
similar  claim with  respect any  intellectual  property  and shall not claim to
acknowledge,  or  permit  any  member  of  its  respective  Group  to  claim  to
acknowledge,  the validity or infringing use of any  intellectual  property of a
third  Person in a manner  that would  hamper or  undermine  the defense of such
infringement or similar claim.

                  (e)  The  obligation  of  the  parties  to  provide  witnesses
pursuant to this Section 8.7 is intended to be  interpreted in a manner so as to
facilitate  cooperation and shall include the obligation to provide as witnesses
inventors  and other  officers  without  regard to  whether  the  witness or the
employer of the witness could assert a possible  business  conflict  (subject to
the exception set forth in the first sentence of Section 8.7(a)).

                  (f) In connection with any matter contemplated by this Section
8.7, the parties will enter into a mutually  acceptable joint defense  agreement
so as to  maintain  to the extent  practicable  any  applicable  attorney-client
privilege or work product immunity of any member of any Group.

                  8.8.  CONFIDENTIALITY.  (a)  Subject to Section  8.9,  each of
AT&T,  Lucent  and NCR,  on behalf of itself and each  member of its  respective
Group,  agrees  to  hold,  and to  cause  its  respective  directors,  officers,
employees,  agents, accountants,  counsel and other advisors and representatives
to hold,  in  strict  confidence,  with at least  the same  degree  of care that
applies to AT&T's confidential and proprietary  information pursuant to policies
in effect as of the Closing Date,  all  Information  concerning  each such other
Group that is


<PAGE>

either in its possession  (including  Information in its possession prior to any
of the date hereof,  the Closing Date or the Distribution  Date) or furnished by
any such other Group or its respective directors,  officers,  employees, agents,
accountants, counsel and other advisors and representatives at any time pursuant
to this Agreement,  any Ancillary Agreement or otherwise,  and shall not use any
such  Information  other than for such purposes as shall be expressly  permitted
hereunder  or  thereunder,  except,  in  each  case,  to the  extent  that  such
Information  has been (i) in the public domain through no fault of such party or
any  member  of such  Group  or any of  their  respective  directors,  officers,
employees, agents, accountants,  counsel and other advisors and representatives,
(ii) later lawfully  acquired from other sources by such party (or any member of
such party's Group) which sources are not themselves bound by a  confidentiality
obligation),   or  (iii)  independently   generated  without  reference  to  any
proprietary or confidential Information of the other party.

                  (b) Each party agrees not to release or disclose, or permit to
be released or disclosed,  any such Information to any other Person,  except its
directors, officers, employees, agents, accountants,  counsel and other advisors
and  representatives  who need to know such Information (who shall be advised of
their  obligations  hereunder  with  respect  to such  Information),  except  in
compliance  with  Section  8.9.  Without   limiting  the  foregoing,   when  any
Information is no longer needed for the purposes  contemplated by this Agreement
or any Ancillary Agreement,  each party will promptly after request of the other
party  either  return to the other  party all  Information  in a  tangible  form
(including  all  copies  thereof  and all notes,  extracts  or  summaries  based
thereon) or certify to the other party that it has  destroyed  such  Information
(and such copies thereof and such notes, extracts or summaries based thereon).

                  8.9. PROTECTIVE  ARRANGEMENTS.  In the event that any party or
any member of its Group either  determines  on the advice of its counsel that it
is required to disclose any  Information  pursuant to applicable law or receives
any demand under lawful process or from any  Governmental  Authority to disclose
or provide  Information  of any other party (or any member of any other  party's
Group)  that is subject to the  confidentiality  provisions  hereof,  such party
shall notify the other party prior to disclosing or providing  such  Information
and shall  cooperate  at the  expense of the  requesting  party in  seeking  any
reasonable protective arrangements requested by such other party. Subject to the
foregoing,  the Person that  received  such request may  thereafter  disclose or
provide  Information  to the  extent  required  by such  law (as so  advised  by
counsel) or by lawful process or such Governmental Authority.

                                   ARTICLE IX
                         ARBITRATION; DISPUTE RESOLUTION

                  9.1. AGREEMENT TO ARBITRATE.  Except as otherwise specifically
provided in any Ancillary Agreement, the procedures for discussion,  negotiation
and  arbitration  set  forth in this  Article  IX shall  apply to all  disputes,
controversies or claims (whether  sounding in contract,  tort or otherwise) that
may  arise  out of or  relate  to,  or arise  under or in  connection  with this
Agreement or any Ancillary Agreement, or the transactions contemplated hereby or
thereby  (including  all  actions  taken  in  furtherance  of  the  transactions
contemplated  hereby  or  thereby  on or  prior  to  the  date  hereof),  or the
commercial or economic  relationship of the parties  relating hereto or thereto,
between or among any member of the AT&T Services Group, the Lucent Group and the
NCR  Group.  Each  party  agrees  on behalf  of  itself  and each  member of its
respective Group that the procedures set forth in this


<PAGE>

Article  IX shall  be the  sole and  exclusive  remedy  in  connection  with any
dispute,  controversy  or claim  relating  to any of the  foregoing  matters and
irrevocably   waives  any  right  to  commence  any  Action  in  or  before  any
Governmental Authority,  except as expressly provided in Sections 9.7(b) and 9.8
and  except to the  extent  provided  under the  Arbitration  Act in the case of
judicial review of arbitration results or awards. Each party on behalf of itself
and each  member of its  respective  Group  irrevocably  waives any right to any
trial by jury with respect to any claim, controversy or dispute set forth in the
first sentence of this Section 9.1.

                  9.2.  ESCALATION.  (a) It is the intent of the  parties to use
their respective  reasonable best efforts to resolve  expeditiously any dispute,
controversy  or claim between or among them with respect to the matters  covered
hereby  that may arise  from time to time on a  mutually  acceptable  negotiated
basis.  In  furtherance  of the  foregoing,  any party  involved  in a  dispute,
controversy or claim may deliver a notice (an "Escalation  Notice") demanding an
in person meeting involving  representatives of the parties at a senior level of
management of the parties (or if the parties agree, of the appropriate strategic
business  unit or division  within such entity).  A copy of any such  Escalation
Notice shall be given to the General  Counsel,  or like officer or official,  of
each party involved in the dispute, controversy or claim (which copy shall state
that it is an  Escalation  Notice  pursuant  to  this  Agreement).  Any  agenda,
location or procedures for such discussions or negotiations  between the parties
may be established by the parties from time to time; provided, however, that the
parties  shall use their  reasonable  best efforts to meet within 30 days of the
Escalation Notice.

                  (b) The parties may, by mutual  consent,  retain a mediator to
aid the parties in their  discussions and  negotiations by informally  providing
advice to the parties.  Any opinion  expressed by the mediator shall be strictly
advisory  and shall  not be  binding  on the  parties,  nor  shall  any  opinion
expressed by the mediator be  admissible  in any  arbitration  proceedings.  The
mediator  may be chosen  from a list of  mediators  previously  selected  by the
parties or by other  agreement of the parties.  Costs of the mediation  shall be
borne  equally by the parties  involved  in the  matter,  except that each party
shall be responsible for its own expenses.  Mediation is not a prerequisite to a
demand for arbitration under Section 9.3.


                  9.3. DEMAND FOR  ARBITRATION.  (a) At any time after the first
to occur of (i) the date of the meeting actually held pursuant to the applicable
Escalation Notice or (ii) 45 days after the delivery of an Escalation Notice (as
applicable,  the "Arbitration  Demand Date"), any party involved in the dispute,
controversy or claim  (regardless of whether such party delivered the Escalation
Notice) may, unless the Applicable Deadline has occurred,  make a written demand
(the  "Arbitration  Demand  Notice")  that the  dispute be  resolved  by binding
arbitration,  which  Arbitration  Demand Notice shall be given to the parties to
the dispute,  controversy  or claim in the manner set forth in Section  12.5. In
the event that any party shall deliver an  Arbitration  Demand Notice to another
party, such other party may itself deliver an Arbitration  Demand Notice to such
first  party with  respect to any  related  dispute,  controversy  or claim with
respect to which the Applicable  Deadline has not passed without the requirement
of  delivering  an  Escalation  Notice.  No party may assert that the failure to
resolve any matter during any discussions or negotiations, the course of conduct
during the  discussions  or  negotiations  or the failure to agree on a mutually
acceptable time, agenda,  location or procedures for the meeting,  in each case,
as  contemplated  by Section 9.2, is a prerequisite  to a demand for arbitration
under Section 9.3. In the event that any party  delivers an  Arbitration  Demand
Notice with respect to any dispute, controversy or


<PAGE>

claim that is the subject of any then  pending  arbitration  proceeding  or of a
previously delivered Arbitration Demand Notice, all such disputes, controversies
and  claims  shall  be  resolved  in the  arbitration  proceeding  for  which an
Arbitration  Demand Notice was first  delivered  unless the arbitrator in his or
her sole discretion determines that it is impracticable or otherwise inadvisable
to do so.


                  (b)  Except  as may be  expressly  provided  in any  Ancillary
Agreement, any Arbitration Demand Notice may be given until one year and 45 days
after  the  later  of the  occurrence  of the act or  event  giving  rise to the
underlying  claim or the date on which  such act or event  was,  or should  have
been,  in the exercise of  reasonable  due  diligence,  discovered  by the party
asserting  the  claim  (as  applicable  and as it may in a  particular  case  be
specifically extended by the parties in writing, the "Applicable Deadline"). Any
discussions,  negotiations  or mediations  between the parties  pursuant to this
Agreement or otherwise will not toll the Applicable  Deadline  unless  expressly
agreed in writing by the parties. Each of the parties agrees on behalf of itself
and each member of its Group that if an  Arbitration  Demand Notice with respect
to a dispute,  controversy  or claim is not given prior to the expiration of the
Applicable  Deadline,  as between or among the  parties and the members of their
Groups, such dispute,  controversy or claim will be barred.  Subject to Sections
9.7(d) and 9.8,  upon  delivery  of an  Arbitration  Demand  Notice  pursuant to
Section 9.3(a) prior to the  Applicable  Deadline,  the dispute,  controversy or
claim shall be decided by a sole  arbitrator  in  accordance  with the rules set
forth in this Article IX.

                  9.4. ARBITRATORS. (a) Within 15 days after a
valid Arbitration
Demand Notice is given, the parties involved in the dispute,
controversy or
claim referenced therein shall attempt to select a sole arbitrator
satisfactory
to all such parties.


                  (b) In the event  that such  parties  are not able  jointly to
select a sole  arbitrator  within such 15-day  period,  such parties  shall each
appoint an arbitrator  (who need not be  disinterested  as to the parties or the
matter) within 30 days after delivery of the Arbitration  Demand Notice.  If one
party  appoints  an  arbitrator  within  such time period and the other party or
parties fail to appoint an arbitrator  within such time period,  the  arbitrator
appointed by the one party shall be the sole arbitrator of the matter.


                  (c)  In the  event  that a  sole  arbitrator  is not  selected
pursuant to paragraph (a) or (b) above and,  instead,  two or three  arbitrators
are selected pursuant to paragraph (b) above, the two or three arbitrators will,
within 30 days  after  the  appointment  of the  later of them to be  appointed,
select an  additional  arbitrator  who shall act as the sole  arbitrator  of the
dispute. After selection of such sole arbitrator,  the initial arbitrators shall
have no  further  role  with  respect  to the  dispute.  In the  event  that the
arbitrators  so appointed do not,  within 30 days after the  appointment  of the
later of them to be appointed,  agree on the  selection of the sole  arbitrator,
any party  involved  in such  dispute  may apply to CPR,  New York,  New York to
select the sole arbitrator,  which selection shall be made by such  organization
within 30 days after such application.  Any arbitrator selected pursuant to this
paragraph (c) shall be disinterested  with respect to any of the parties and the
matter and shall be reasonably competent in the applicable subject matter.

                  (d) The sole  arbitrator  selected  pursuant to paragraph (a),
(b) or (c)  above  will set a time for the  hearing  of the  matter  which  will
commence  no  later  than 90 days  after  the  date of  appointment  of the sole
arbitrator pursuant to paragraph (a), (b) or (c) above and which hearing will be
no longer than 30 days (unless in the judgment of the  arbitrator  the matter is
unusually complex and sophisticated and thereby requires a longer time, in which
event such hearing shall be no longer than 90 days). The final decision of


<PAGE>

such  arbitrator  will be  rendered  in writing to the parties not later than 60
days after the last  hearing  date,  unless  otherwise  agreed by the parties in
writing.

                  (e) The place of any  arbitration  hereunder will be New York,
New York, unless otherwise agreed by the parties.


                  9.5.  HEARINGS.  Within the time period  specified  in Section
9.4(d), the matter shall be presented to the arbitrator at a hearing by means of
written  submissions  of  memoranda  and  verified  witness  statements,   filed
simultaneously, and responses, if necessary in the judgment of the arbitrator or
both  the  parties.  If  the  arbitrator  deems  it to be  essential  to a  fair
resolution of the dispute,  live  cross-examination or direct examination may be
permitted,  but is not generally  contemplated  to be necessary.  The arbitrator
shall actively  manage the arbitration  with a view to achieving a just,  speedy
and  cost-effective  resolution  of  the  dispute,  claim  or  controversy.  The
arbitrator  may,  in his or her  discretion,  set time and  other  limits on the
presentation  of each party's  case,  its  memoranda or other  submissions,  and
refuse to receive any proffered  evidence,  which the arbitrator,  in his or her
discretion, finds to be cumulative,  unnecessary, irrelevant or of low probative
nature.  Except as otherwise set forth herein, any arbitration hereunder will be
conducted in accordance with the CPR Rules for  Non-Administered  Arbitration of
Business Disputes then prevailing  (except that the fee schedule of CPR will not
apply).  Except as expressly  set forth in Section  9.8(b),  the decision of the
arbitrator will be final and binding on the parties, and judgment thereon may be
had and will be enforceable in any court having  jurisdiction  over the parties.
Arbitration  awards will bear  interest at an annual rate of the Prime Rate plus
2% per annum.  To the  extent  that the  provisions  of this  Agreement  and the
prevailing  rules of the CPR conflict,  the provisions of this  Agreement  shall
govern.



                  9.6.  DISCOVERY  AND  CERTAIN  OTHER  MATTERS.  (a) Any  party
involved in the applicable dispute may request limited document  production from
the other party or parties of specific and expressly  relevant  documents,  with
the reasonable  expenses of the producing party incurred in such production paid
by the requesting  party. Any such discovery (which rights to documents shall be
substantially  less than document  discovery rights prevailing under the Federal
Rules of Civil Procedure) shall be conducted  expeditiously  and shall not cause
the hearing  provided for in Section 9.5 to be adjourned  except upon consent of
all parties involved in the applicable dispute or upon an extraordinary  showing
of cause  demonstrating  that such  adjournment is necessary to permit discovery
essential to a party to the proceeding.  Depositions,  interrogatories  or other
forms of discovery  (other than the document  production  set forth above) shall
not occur except by consent of the parties  involved in the applicable  dispute.
Disputes  concerning  the scope of document  production  and  enforcement of the
document  production  requests will be  determined  by written  agreement of the
parties involved in the applicable  dispute or, failing such agreement,  will be
referred to the  arbitrator  for  resolution.  All  discovery  requests  will be
subject to the parties' rights to claim any applicable privilege. The arbitrator
will adopt  procedures to protect the  proprietary  rights of the parties and to
maintain the confidential  treatment of the arbitration  proceedings  (except as
may be required by law). Subject to the foregoing, the arbitrator shall have the
power to issue  subpoenas to compel the production of documents  relevant to the
dispute, controversy or claim.


                  (b) The  arbitrator  shall  have full power and  authority  to
determine issues of arbitrability but shall otherwise be limited to interpreting
or  construing  the  applicable  provisions  of this  Agreement or any Ancillary
Agreement,  and will have no authority or power to limit, expand,  alter, amend,
modify,  revoke or suspend any  condition or provision of this  Agreement or any
Ancillary Agreement; it being understood, however, that the arbitrator


<PAGE>

will have full  authority to implement the  provisions of this  Agreement or any
Ancillary  Agreement,  and to fashion appropriate  remedies for breaches of this
Agreement (including interim or permanent injunctive relief);  provided that the
arbitrator  shall not have (i) any  authority in excess of the authority a court
having  jurisdiction  over the parties and the controversy or dispute would have
absent these arbitration provisions or (ii) any right or power to award punitive
or treble  damages.  It is the  intention  of the  parties  that in  rendering a
decision  the  arbitrator  give  effect  to the  applicable  provisions  of this
Agreement  and the  Ancillary  Agreements  and follow  applicable  law (it being
understood  and  agreed  that  this  sentence  shall not give rise to a right of
judicial review of the arbitrator's award).

                  (c) If a party  fails or refuses to appear at and  participate
in an  arbitration  hearing  after  due  notice,  the  arbitrator  may  hear and
determine the controversy upon evidence produced by the appearing party.

                  (d)  Arbitration  costs  will be borne  equally  by each party
involved in the matter,  except that each party will be responsible  for its own
attorney's  fees and other costs and expenses,  including the costs of witnesses
selected by such party.

                  9.7. CERTAIN  ADDITIONAL  MATTERS.  (a) Any arbitration  award
shall be a bare award  limited to a holding  for or against a party and shall be
without  findings as to facts,  issues or  conclusions  of law  (including  with
respect to any matters  relating to the validity or  infringement  of patents or
patent  applications) and shall be without a statement of the reasoning on which
the award rests,  but must be in adequate form so that a judgment of a court may
be entered  thereupon.  Judgment  upon any  arbitration  award  hereunder may be
entered in any court having jurisdiction thereof.

                  (b)  Prior to the time at which  an  arbitrator  is  appointed
pursuant to Section  9.4, any party may seek one or more  temporary  restraining
orders in a court of  competent  jurisdiction  if necessary in order to preserve
and protect the status quo.  Neither the request for, or grant or denial of, any
such temporary  restraining  order shall be deemed a waiver of the obligation to
arbitrate  as set forth  herein and the  arbitrator  may  dissolve,  continue or
modify any such order.  Any such  temporary  restraining  order shall  remain in
effect  until the first to occur of the  expiration  of the order in  accordance
with its terms or the dissolution thereof by the arbitrator.

                  (c) Except as required by law,  the  parties  shall hold,  and
shall cause their respective officers,  directors,  employees,  agents and other
representatives  to hold,  the  existence,  content and result of  mediation  or
arbitration in confidence in accordance  with the provisions of Article VIII and
except as may be  required  in order to enforce  any award.  Each of the parties
shall request that any mediator or arbitrator  comply with such  confidentiality
requirement.

                  (d) In the event  that at any time the sole  arbitrator  shall
fail to serve as an  arbitrator  for any reason,  the parties shall select a new
arbitrator  who  shall be  disinterested  as to the  parties  and the  matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator.  The extent,  if any, to which testimony  previously  given shall be
repeated  or as to  which  the  replacement  arbitrator  elects  to  rely on the
stenographic  record (if there is one) of such testimony  shall be determined by
the replacement arbitrator.


                  9.8. LIMITED COURT ACTIONS. (a) Notwithstanding
anything
herein to the contrary, in the event that any party reasonably
determines the
amount in controversy in any dispute, controversy or claim (or any
series of
related disputes, controversies or claims)


<PAGE>

under this Agreement or any Ancillary  Agreement is, or is reasonably  likely to
be, in excess of $100 million and if such party desires to commence an Action in
lieu of complying with the  arbitration  provisions of this Article,  such party
shall so state in its Arbitration  Demand Notice or by notice given to the other
parties  within 20 days  after  receipt of an  Arbitration  Demand  Notice  with
respect  thereto.  If the other parties to the arbitration do not agree that the
amount in controversy  in such dispute,  controversy or claim (or such series of
related disputes, controversies or claims) is, or is reasonably likely to be, in
excess of $100 million,  the arbitrator  selected pursuant to Section 9.4 hereof
shall decide whether the amount in  controversy in such dispute,  controversy or
claim (or such series of related  disputes,  controversies  or claims) is, or is
reasonably  likely to be, in excess of $100 million.  The arbitrator shall set a
date that is no later than ten days after the date of his or her appointment for
submissions  by the parties with  respect to such issue.  There shall not be any
discovery in connection with such issue.  The arbitrator shall render his or her
decision on such issue  within five days of such date so set by the  arbitrator.
In the event that the  arbitrator  determines  that the amount in controversy in
such  dispute,  controversy  or  claim  (or such  series  of  related  disputes,
controversies  or  claims)  is or is  reasonably  likely to be in excess of $100
million,  the  provisions  of Sections  9.4(d) and (e),  9.5,  9.6, 9.7 and 9.10
hereof shall not apply and on or before (but,  except as expressly  set forth in
Section  9.8(b),  not  after)  the  tenth  business  day  after the date of such
decision,  any party to the arbitration  may elect,  in lieu of arbitration,  to
commence an Action with respect to such dispute,  controversy  or claim (or such
series of related  disputes,  controversies or claims) in any court of competent
jurisdiction.  If the arbitrator  does not so determine,  the provisions of this
Article  (including  with  respect  to  time  periods)  shall  apply  as  if  no
determinations were sought or made pursuant to this Section 9.8(a).


                  (b) In the event that an  arbitration  award in excess of $100
million is issued in any arbitration  proceeding commenced hereunder,  any party
may,  within  60 days  after  the  date  of  such  award,  submit  the  dispute,
controversy or claim (or series of related  disputes,  controversies  or claims)
giving rise thereto to a court of competent jurisdiction,  regardless of whether
such party or any other party sought to commence an Action in lieu of proceeding
with  arbitration  in  accordance  with  Section  9.8(a).  In  such  event,  the
applicable  court may elect to rely on the record  developed in the  arbitration
or, if it determines  that it would be advisable in connection  with the matter,
allow  the  parties  to  seek  additional  discovery  or to  present  additional
evidence.  Each party shall be entitled to present  arguments  to the court with
respect to whether any such additional  discovery or evidence shall be permitted
and with  respect  to all other  matters  relating  to the  applicable  dispute,
controversy or claim (or series of related disputes, controversies or claims).


                  (c)  No  party  shall  raise  as  a  defense  the  statute  of
limitations  if the  applicable  Arbitration  Demand  Notice was delivered on or
prior to the Applicable Deadline and, if applicable,  if the matter is submitted
to a court of  competent  jurisdiction  within the 60-day  period  specified  in
Section 9.8(b).

                  9.9.  CONTINUITY OF SERVICE AND PERFORMANCE.  Unless otherwise
agreed in writing,  the parties will  continue to provide  service and honor all
other commitments  under this Agreement and each Ancillary  Agreement during the
course of dispute resolution  pursuant to the provisions of this Article IX with
respect to all matters not subject to such dispute, controversy or claim.

                  9.10. LAW GOVERNING ARBITRATION PROCEDURES. The
interpretation
of the provisions of this Article IX, only insofar as they relate
to the
agreement to arbitrate and


<PAGE>

any procedures  pursuant  thereto,  shall be governed by the Arbitration Act and
other applicable federal law. In all other respects,  the interpretation of this
Agreement shall be governed as set forth in Section 12.2.

                                    ARTICLE X
                   FURTHER ASSURANCES AND ADDITIONAL COVENANTS

                  10.1.  FURTHER  ASSURANCES.  (a) In  addition  to the  actions
specifically  provided  for  elsewhere  in this  Agreement,  each of the parties
hereto shall use its reasonable best efforts, prior to, on and after the Closing
Date,  to take,  or cause to be taken,  all  actions,  and to do, or cause to be
done, all things,  reasonably  necessary,  proper or advisable under  applicable
laws,   regulations   and  agreements  to  consummate  and  make  effective  the
transactions contemplated by this Agreement and the Ancillary Agreements.

                  (b) Without limiting the foregoing, prior to, on and after the
Closing Date,  each party hereto shall  cooperate  with the other  parties,  and
without any further  consideration,  but at the expense of the requesting party,
to  execute  and  deliver,  or use its  reasonable  best  efforts to cause to be
executed and delivered,  all instruments,  including  instruments of conveyance,
assignment  and  transfer,  and to make all  filings  with,  and to  obtain  all
consents,  approvals or  authorizations  of, any  Governmental  Authority or any
other Person under any permit, license, agreement, indenture or other instrument
(including any Consents or Governmental  Approvals),  and to take all such other
actions as such party may  reasonably  be  requested  to take by any other party
hereto from time to time,  consistent  with the terms of this  Agreement and the
Ancillary Agreements, in order to effectuate the provisions and purposes of this
Agreement  and the Ancillary  Agreements  and the transfers of the Lucent Assets
and the  assignment  and  assumption  of the  Lucent  Liabilities  and the other
transactions  contemplated  hereby and thereby.  Without limiting the foregoing,
each party will, at the reasonable request, cost and expense of any other party,
take such other  actions as may be  reasonably  necessary  to vest in such other
party good and marketable title, free and clear of any Security Interest, if and
to the extent it is practicable to do so.

                  (c) On or prior to the Closing Date,  AT&T,  Lucent and NCR in
their  respective  capacities  as  direct  and  indirect  stockholders  of their
respective  Subsidiaries,  shall each  ratify any actions  which are  reasonably
necessary or desirable to be taken by AT&T,  Lucent, NCR or any other Subsidiary
of AT&T, as the case may be, to effectuate the transactions contemplated by this
Agreement.  On or prior to the  Closing  Date,  AT&T and  Lucent  shall take all
actions as may be necessary to approve the stock-based employee benefit plans of
Lucent in order to satisfy the  requirement of Rule 16b-3 under the Exchange Act
and Section 162(m) of the Code.

                  (d) The parties  hereto agree to take any  reasonable  actions
necessary in order for the  Distribution  to qualify as a tax-free  distribution
pursuant to Section 355 of the Code.

                  (e) AT&T,  Lucent  and NCR,  and each of the  members of their
respective Groups, waive (and agree not to assert against any of the others) any
claim or demand  that any of them may have  against  any of the  others  for any
Liabilities  or other  claims  relating to or arising out of: (i) the failure of
Lucent or any member of the Lucent Group,  on the one hand,  or of AT&T,  NCR or
any member of the AT&T  Services  Group or the NCR Group,  on the other hand, to
provide any notification or disclosure required under any state


<PAGE>

Environmental  Law in connection  with the Separation or the other  transactions
contemplated  by this  Agreement,  including  the  transfer by any member of any
Group to any member of any other Group of  ownership or  operational  control of
any Assets not  previously  owned or  operated by such  transferee;  or (ii) any
inadequate,  incorrect or incomplete  notification or disclosure  under any such
state  Environmental  Law by  the  applicable  transferor.  To  the  extent  any
Liability to any  Governmental  Authority or any third Person  arises out of any
action or inaction  described in clause (i) or (ii) above, the transferee of the
applicable Asset hereby assumes and agrees to pay any such Liability.

                  (f) Prior to the Closing  Date,  if one or more of the parties
identifies any commercial or other service that is needed to assure a smooth and
orderly  transition of the businesses in connection with the consummation of the
transactions  contemplated  hereby,  and that is not  otherwise  governed by the
provisions  of this  Agreement  or any  Ancillary  Agreement,  the parties  will
cooperate in  determining  whether there is a mutually  acceptable  arm's-length
basis on which one or more of the other parties will provide such service.

                  10.2.  QUALIFICATION  AS  TAX-FREE  DISTRIBUTION.   After  the
Closing  Date,  none of AT&T,  Lucent or NCR shall take, or permit any member of
its respective  Group to take, any action which could  reasonably be expected to
prevent the Distribution from qualifying as a tax-free  distribution  within the
meaning of Section 355 of the Code or any other transaction contemplated by this
Agreement  or any  Ancillary  Agreement  which is  intended by the parties to be
tax-free from failing so to qualify.  Without limiting the foregoing,  after the
Closing Date and on or prior to the Distribution Date, Lucent shall not issue or
grant,  and shall not permit  any member of the Lucent  Group to issue or grant,
directly  or  indirectly,  any  shares of  Lucent  Common  Stock or any  rights,

                                  MISCELLANEOUS

                  12.1. COUNTERPARTS; ENTIRE AGREEMENT; CORPORATE
POWER. (a)
This Agreement and each Ancillary Agreement may be executed in one
or more

                  (b)  This  Agreement,  and the  Ancillary  Agreements  and the
Exhibits,  Schedules  and  Appendices  hereto  and  thereto  contain  the entire

understandings,  commitments  and  conversations  with  respect to such  subject
matter and there are no agreements or  understandings  between the parties other
than those set forth or referred to herein or therein.

                  (c) AT&T  represents on behalf of itself and each other member
of the AT&T Services Group, Lucent represents on behalf of itself and each other
member of the Lucent Group and NCR represents on behalf of itself and each other
member of the NCR Group as follows:

                  (i) each such  Person  has the  requisite
corporate  or other

other  action
         necessary  in  order  to  execute,  deliver  and
perform  each of this

Agreement to which it
         is a party has been duly executed and delivered by it and
constitutes a
         valid and binding  agreement of it enforceable  in
accordance  with the
         terms thereof.

                  (d) Each  party  hereto  acknowledges  that it and each  other
party hereto is executing  certain of the  Ancillary  Agreements  by  facsimile,
stamp or mechanical  signature.  Each party hereto expressly adopts and confirms
each such facsimile,  stamp or mechanical  signature made in its respective name
as if it were a manual  signature,  agrees that it will not assert that any such
signature  is not  adequate  to bind such party to the same extent as if it were
signed  manually  and agrees that at the  reasonable  request of any other party
hereto at any time it will as promptly as reasonably practicable cause each such
Ancillary  Agreement to be manually executed (any such execution to be as of the
date of the initial date thereof).

                  (e)  Notwithstanding  any  provision of this  Agreement or any
Ancillary  Agreement,  neither AT&T, Lucent nor NCR shall be required to take or
omit to take any act that would  violate its  fiduciary  duties to any  minority
stockholders  of  AT&T  Capital   Corporation  or  any  other  non-wholly  owned
Subsidiary of AT&T,  Lucent or NCR, as the case may be (it being understood that
directors'  qualifying  shares or  similar  interests  will be  disregarded  for
purposes of determining whether a Subsidiary is wholly owned).

                  12.2. GOVERNING LAW. Except as set forth in
Section 9.10, this
Agreement and, unless  expressly  provided  therein,  each
Ancillary  Agreement,
shall be governed by and construed and  interpreted in accordance  with the laws
of the State of New York (other than as to its laws of  arbitration  which shall
be governed under the Arbitration Act or other



<PAGE>

applicable federal law pursuant to Section 9.10),  irrespective of the choice of
laws principles of the State of New York, as to all matters,  including  matters
of validity, construction, effect, enforceability, performance and remedies.

                  12.3. ASSIGNABILITY.  (a) Except as set forth in any Ancillary
Agreement, this Agreement and each Ancillary Agreement shall be binding upon and
inure to the benefit of the parties hereto and thereto,  respectively, and their
respective  successors and assigns;  provided,  however, that no party hereto or
thereto may assign its respective rights or delegate its respective  obligations

written consent of the other parties hereto or thereto.

                  (b)  Lucent  agrees and  acknowledges  on behalf of itself and
each  other  member of the  Lucent  Group that (i) AT&T and NCR may enter into a
separation and  distribution  agreement and other  agreements and instruments in

obligation  to proceed with the NCR  Distribution,  and (iv) except as set forth
below,  all of the  rights  and  obligations  of the NCR  Group  shall  continue

technical or other  nonmaterial  amendments  to this  Agreement or any Ancillary
Agreement  are  advisable  in  connection  with  the  NCR  Distribution  or  the
separation  of the NCR Business  from the AT&T  Services  Business,  Lucent will
reasonably cooperate with AT&T and NCR in connection therewith for no additional
consideration.  Without limiting the foregoing,  effective immediately on notice

hereunder or under any Ancillary  Agreement (and any rights of any member of the
NCR Group in  connection  therewith)  and all  members  of the NCR  Group  shall
thereupon automatically be released therefrom.



                  12.4.    THIRD   PARTY    BENEFICIARIES.    Except   for   the
indemnification  rights  under this  Agreement  of any AT&T  Indemnitee,  Lucent
Indemnitee or NCR  Indemnitee in their  respective  capacities as such,  (a) the
provisions  of this  Agreement and each  Ancillary  Agreement are solely for the
benefit of the parties and are not intended to confer upon any Person except the
parties  any  rights or  remedies  hereunder,  and (b) there are no third  party
beneficiaries  of this  Agreement or any  Ancillary  Agreement  and neither this
Agreement  nor any Ancillary  Agreement  shall provide any third person with any
remedy,  claim,  liability,  reimbursement,  claim of action  or other  right in
excess of those  existing  without  reference to this Agreement or any Ancillary
Agreement. No party hereto shall have any right, remedy or claim with respect to
any provision of this  Agreement or any  Ancillary  Agreement to the extent such
provision  relates solely to the other two parties hereto or the members of such
other two parties'  respective Groups. No party shall be required to deliver any
notice under this Agreement or under any Ancillary  Agreement to any other party
with  respect to any matter in which  such other  party has no right,  remedy or
claim.

                  12.6. SEVERABILITY.  If any provision of this Agreement or any
Ancillary  Agreement or the application thereof to any Person or circumstance is
determined  by a  court  of  competent  jurisdiction  to  be  invalid,  void  or
unenforceable, the remaining provisions hereof or thereof, or the application of
such provision to Persons or circumstances or in jurisdictions  other than those
as to which it has been held  invalid  or  unenforceable,  shall  remain in full
force  and  effect  and shall in no way be  affected,  impaired  or  invalidated
thereby,  so  long  as the  economic  or  legal  substance  of the  transactions
contemplated  hereby  or  thereby,  as the case may be, is not  affected  in any
manner  adverse  to any  party.  Upon  such  determination,  the  parties  shall
negotiate in good faith in an effort to agree upon such a suitable and equitable
provision to effect the original intent of the parties.

                  12.7.  FORCE  MAJEURE.  No party shall be deemed in default of
this  Agreement  or any  Ancillary  Agreement  to the  extent  that any delay or

Ancillary  Agreement  results from any cause beyond its  reasonable  control and
without its fault or negligence,  such as acts of God, acts of civil or military
authority, embargoes,  epidemics, war, riots, insurrections,  fires, explosions,
earthquakes,  floods,  unusually  severe weather  conditions,  labor problems or
unavailability  of parts,  or, in the case of computer  systems,  any failure in
electrical  or air  conditioning  equipment.  In the  event of any such  excused
delay, the time for performance shall be extended for a period equal to the time
lost by reason of the delay.

                  12.8.  PUBLICITY.  Prior to the Distribution,  each of Lucent,

or any of the other  transactions  contemplated  hereby  and prior to making any
filings with any Governmental Authority with respect thereto.



<PAGE>

                  12.9.  EXPENSES.   Except  as  expressly  set
forth  in  this
Agreement  (including  Section  3.1(h)  hereof) or in any
Ancillary  Agreement,

costs and expenses paid or incurred in connection with the Distribution will be
paid by AT&T.

                  12.10. HEADINGS. The article, section and
paragraph headings

whether AT&T shall consummate, delay, modify or abandon the NCR Distribution.

                  12.12. WAIVERS OF DEFAULT. Waiver by any party
of any default
by the other party of any provision of this Agreement or any
Ancillary Agreement
shall not be deemed a waiver by the waiving party of any
subsequent or other
default, nor shall it prejudice the rights of the other party.

                  12.13.  SPECIFIC  PERFORMANCE.  In the event of any  actual or
threatened default in, or breach of, any of the terms, conditions and provisions
of this  Agreement or any Ancillary  Agreement,  the party or parties who are or
are to be thereby  aggrieved  shall have the right to specific  performance  and
injunctive or other equitable  relief of its rights under this Agreement or such
Ancillary Agreement, in addition to any and all other rights and remedies at law
or in equity, and all such rights and remedies shall be cumulative.  The parties
agree that the remedies at law for any breach or  threatened  breach,  including
monetary damages, are inadequate  compensation for any loss and that any defense
in any action for specific performance that a remedy at law would be adequate is
waived.  Any  requirements  for the  securing  or  posting of any bond with such
remedy are waived.

                  12.14. AMENDMENTS.  (a) No provisions of this Agreement or any
Ancillary Agreement shall be deemed waived, amended, supplemented or modified by
any party,  unless such waiver,  amendment,  supplement  or  modification  is in
writing and signed by the authorized representative of the party against whom it
is sought to enforce such waiver, amendment, supplement or modification. Without
limiting the foregoing, the parties agree that any waiver, amendment, supplement
or modification of this Agreement or any Ancillary Agreement that solely relates
to and  affects  only two of the three  parties  hereto  shall not  require  the
consent of the third party hereto.

                  (b) Without  limiting the  foregoing,  the parties  anticipate
that,  prior to the Closing Date, some or all of the Schedules to this Agreement
may be amended or supplemented  and, in such event, such amended or supplemented
Schedules shall be attached hereto in lieu of the original Schedules.

                  (b)  AT&T  and  NCR  shall  take  all  such  action  as may be

have  the  sole  discretion  to  determine  the  NCR  Record
Date  and  the NCR

time as each of the following conditions shall have been satisfied or shall have
been waived by the AT&T Board in its sole discretion:

                  (a) a private letter ruling from the Internal
Revenue Service
         shall have been obtained,  and shall continue in effect,
to the effect
         that,  among  other  things,  the NCR  Distribution
will  qualify as a
         tax-free distribution for federal income tax purposes
under Section 355
         of  the  Code,   and  such  ruling  shall  be  in  form
and  substance
         satisfactory to AT&T in its sole discretion;

                  (b) any material Governmental Approvals and
Consents necessary
         to consummate the NCR  Distribution  shall have been
obtained and be in
         full force and effect;

                  (c) no  order,  injunction  or  decree  issued
by any court or
         agency  of  competent   jurisdiction   or  other  legal
restraint  or
         prohibition  preventing the consummation of the NCR
Distribution  shall
         be in effect and no other event shall have  occurred or
failed to occur
         that prevents the consummation of the NCR Distribution;

         among  other  matters,   whether  the  NCR
Distribution  and  related
         transactions  may be effected  without  registration  of
the NCR Common
         Stock  (and  related   Preferred  Share  Purchase
Rights)  under  the
         Securities Act;





<PAGE>

                  (f) the NCR Common Stock (and related Preferred
Share Purchase
         Rights)  shall have been  accepted  for  listing by the

         mutually agreeable stock exchange or quotations system;
and

                  (g) the AT&T Board shall have formally approved
the
         Distribution;

provided  that  the  satisfaction  of  such  conditions  shall  not  create  any
obligation on the part of AT&T,  NCR or any other Person to effect or to seek to
effect the NCR  Distribution  or in any way limit AT&T's right to terminate this
Agreement  as set forth in  Section  7.1 or alter the  consequences  of any such
termination from those specified in Section 7.2.

Common Stock in the NCR Distribution.  Holders that receive  certificates in the
NCR  Distribution  and  holders  that  receive  less than one whole share of NCR
Common Stock in the NCR Distribution will receive cash in lieu of such
fractional  shares as contemplated  hereby. As soon as practicable after the NCR
Distribution  Date,  AT&T  shall  direct  the Agent to  determine  the number of
fractional  shares of NCR Common  Stock  allocable  to each  holder of record or
beneficial  owner of AT&T Common  Stock as of the Record Date that will  receive
cash in lieu of such fractional  shares, to aggregate all such fractional shares
and sell the whole shares obtained by aggregating such fractional  shares either
in open  market  transactions  or  otherwise,  in each  case at then  prevailing
trading  prices,  and to cause to be  distributed to each such holder or for the
benefit of each such  beneficial  owner, in lieu of any fractional  share,  such
holder's or owner's  ratable  share of the  proceeds of such sale,  after making
appropriate  deductions of the amount required to be withheld for federal income
tax purposes  and after  deducting  an amount  equal to all  brokerage  charges,
commissions and transfer taxes attributed to such sale. AT&T and the Agent shall
use their  reasonable  best efforts to aggregate the shares of AT&T Common Stock
that may be held by any beneficial  owner thereof  through more than one account
in determining the fractional share allocable to such beneficial owner.

                   (i) any Liability provided in or resulting from
any agreement
         among any members of the AT&T  Services  Group or the NCR
Group that is
         specified in the  Separation  and  Distribution
Agreement,  in Section
         3.4(b)  or  the  applicable  Schedules  hereto  or
thereto  as  not to
         terminate as of the Closing Date or as of the NCR
Distribution Date, as
         the  case  may  be,  or any  other  Liability  so
specified  as not to
         terminate as of the Closing Date or NCR Distribution Date;

                  (ii)  any   Liability,   contingent  or
otherwise,   assumed,
         transferred, assigned or allocated to the Group of which
such Person is
         a member in accordance  with,  or any other  Liability of
any member of
         any Group under, any Transaction Agreement;





<PAGE>

                 (iii) any  Liability  that the parties may have
with respect to
         indemnification  or contribution  pursuant to this
Agreement for claims
         brought against the parties by third Persons,  which
Liability shall be
         governed by the provisions of this Article IV and by the
Separation and
         Distribution  Agreement,   and,  if  applicable,   by
the  appropriate
         provisions of the Ancillary Agreements or NCR Ancillary
Agreements; or

                  (iv) any  Liability  the release of which would
result in the
         release of any Person  other than a Person  released
pursuant  to this
         Section  4.1;  provided  that the  parties  agree not to
bring  suit or
         permit any of their  Subsidiaries to bring suit against
any such Person
         with  respect to any  Liability to the extent that such
Person would be
         released with respect to such Liability by this Section
4.1 but for the
         provisions of this clause (iv).

                  (d) NCR shall not make, and shall not permit any member of the
NCR Group to make,  any claim or demand,  or commence any Action  asserting  any
claim or demand,  including any claim of  contribution  or any  indemnification,
against  AT&T,  any  member of the AT&T  Services  Group,  or any  other  Person
released  pursuant to Section 4.1(a),  with respect to any Liabilities  released
pursuant to Section  4.1(a).  AT&T shall not, and shall not permit any member of
the AT&T  Services  Group,  to make any claim or demand,  or commence any Action
asserting  any  claim or  demand,  including  any claim of  contribution  or any
indemnification, against NCR or any member of the NCR Group, or any other Person
released  pursuant to Section 4.1(b),  with respect to any Liabilities  released
pursuant to Section 4.1(b).

                  (e) It is the  intent of each of AT&T and NCR by virtue of the
provisions  of this Section 4.1 to provide for a full and  complete  release and
discharge  of all  Liabilities  existing  or  arising  from all acts and  events
occurring  or failing to occur or alleged to have  occurred or to have failed to
occur and all  conditions  existing or alleged to have  existed on or before the
NCR Distribution  Date,  between or among NCR or any member of the NCR Group, on
the one hand,  and AT&T or any member of the AT&T Services  Group,  on the other
hand (including any contractual  agreements or arrangements  existing or alleged
to exist  between or among any such  members  on or before the NCR  Distribution
Date),  except as expressly  set forth in Section  4.1(c).  At any time,  at the
request of any other party, each party shall cause each member of its respective
Group to execute and deliver releases reflecting the provisions hereof.

                  4.2.  INDEMNIFICATION BY NCR. NCR shall indemnify,  defend and
hold harmless  AT&T,  each member of the AT&T  Services  Group and each of their
respective directors,  officers and employees, and each of the heirs, executors,
successors  and  assigns  of any  of  the  foregoing  (collectively,  the  "AT&T
Indemnitees"),  from and against any and all Liabilities of the AT&T Indemnitees
relating  to,  arising  out of or  resulting  from  any of the  following  items
(without duplication),  in each case whether arising before, on or after the NCR
Distribution Date:

                  (a) the failure of NCR or any other member of
the NCR Group or
         any other Person to pay,  perform or otherwise  promptly
discharge any
         Liabilities of any mem-

         ber of the NCR Group in accordance with their respective

hereof;

                  (b) the NCR Business (including any claim by any
creditor of
         AT&T UK Holdings Ltd. to the extent relating to the NCR

         or any NCR Covered Liability;

                  (c) any Asset (including contracts,  agreements,

         and  leasehold  interests)  of any  member of the NCR
Group at any time
         (other than Assets transferred to any member of the AT&T
Services Group
         prior  to the NCR  Distribution  Date),  and any
contract,  agreement,
         letter of credit or other  commitment or obligation
listed on Schedule
         4.2 hereof;

                  (d) the  operation  of the NCR  Business,  as
conducted at any
         time prior to, on or after the NCR  Distribution  Date
(including  any
         Liability  relating  to,  arising out of or  resulting
from any act or
         failure  to  act  by  any  director,   officer,
employee,   agent  or
         representative  (whether  or not such act or  failure  to
act is or was
         within such Person's authority));

                          (e) any guarantee, indemnity,
                          representation, warranty or
         other  Liability of or made by any member of the AT&T

         respect of any Liability or alleged  Liability of any
member of the NCR
         Group;

                  (f) any  breach by NCR or any  member of the NCR
Group of this
         Agreement,  the Separation and  Distribution  Agreement,
any Ancillary
         Agreement or any of the NCR Ancillary Agreements;

                  (g) any  Liabilities  relating to, arising out
of or resulting
         from the NCR Business (including any NCR Covered
Liabilities) for which
         AT&T has agreed to indemnify and hold  harmless the
Lucent  Indemnitees
         pursuant  to  Section  5.3(a)  of  the   Separation
and   Distribution
         Agreement;

                  (h) actions taken by any member of the AT&T

         any member of the NCR Group pursuant to the Separation

                  (i) any untrue  statement  or alleged  untrue
statement  of a
         material fact or omission or alleged  omission to state a
material fact
         required  to be stated  therein  or  necessary  to make
the  statements
         therein not misleading,  with respect to all
information  contained in
         the NCR Information Statement or NCR Form 10; and

                  (j) any  Liability  relating  to,  arising out
of or resulting
         from any actual or threatened  Action or other claim
alleging that any
         Liability was  improperly  allocated to the NCR Group or
that any Asset
         was  improperly  withheld from the NCR Group,  in each
case pursuant to
         any of the Transaction Agreements.





<PAGE>

Nothing in this  Agreement  shall be deemed to amend or modify Section 5.3(c) of
the Separation and  Distribution  Agreement and the provisions of the Separation
and Distribution Agreement shall govern matters covered thereby.

                  4.3. INDEMNIFICATION BY AT&T. (a) AT&T shall indemnify, defend
and hold harmless NCR, each member of the NCR Group and each of their respective
directors, officers and employees, and each of the heirs, executors,  successors
and assigns of any of the foregoing (collectively, the "NCR Indemnitees"),  from
and against any and all Liabilities of the NCR Indemnitees  relating to, arising
out of or resulting from any of the following  items (without  duplication),  in
each case whether arising before, on or after the NCR Distribution Date:

                   (i) the failure of AT&T or any other member of
the AT&T Group
         or any other Person to pay, perform or otherwise promptly
discharge any
         Liabilities  of the AT&T  Services  Group whether prior
to or after the
         NCR Distribution Date or the date hereof;

                  (ii) the AT&T Services Business (including any
claim by any
         creditor of AT&T UK Holdings Ltd. to the extent relating
to the AT&T
         Services Business conducted by such entity) or any
Liability of the
         AT&T Services Group; and

                 (iii)  any  breach by AT&T or any  member of the
AT&T  Services
         Group of this Agreement, the Separation and Distribution
Agreement, any
         Ancillary Agreement or any of the NCR Ancillary
Agreements;

provided however that this Section 4.3 shall not apply to any
Liability relating
to the NCR Business.

                  4.4. INDEMNIFICATION OBLIGATIONS NET OF INSURANCE PROCEEDS AND
OTHER  AMOUNTS.   (a)  The  parties   intend  that  any  Liability   subject  to
indemnification  or  reimbursement  pursuant  to this  Article IV will be net of
Insurance   Proceeds  that  actually   reduce  the  amount  of  the   Liability.
Accordingly, the amount which any party (an "Indemnifying Party") is required to
pay to any Person entitled to  indemnification  hereunder (an "Indemnitee") will
be reduced by any Insurance  Proceeds  theretofore  actually  recovered by or on
behalf of the Indemnitee in reduction of the related Liability. If an Indemnitee
receives a payment (an "Indemnity  Payment")  required by this Agreement from an
Indemnifying  Party  in  respect  of any  Liability  and  subsequently  receives
Insurance  Proceeds,  then the Indemnitee will pay to the Indemnifying  Party an
amount equal to the excess of the Indemnity  Payment received over the amount of
the  Indemnity  Payment  that  would  have  been due if the  Insurance  Proceeds
recovery had been received,  realized or recovered before the Indemnity  Payment
was made.

                  (b) An insurer who would  otherwise  be  obligated  to pay any
claim shall not be  relieved  of the  responsibility  with  respect  thereto or,
solely by virtue of the indemnification  provisions hereof, have any subrogation
rights with respect  thereto,  it being expressly  understood and agreed that no
insurer or any other third party shall be entitled to a "windfall"





<PAGE>

(i.e.,  a benefit  they would not be  entitled  to receive in the absence of the
indemnification provisions) by virtue of the indemnification provisions hereof.

                  4.5. PROCEDURES FOR INDEMNIFICATION OF THIRD PARTY CLAIMS. (a)
If an Indemnitee  shall receive notice or otherwise  learn of the assertion by a
Person  (including any  Governmental  Authority) who is not a member of the AT&T
Services Group or the NCR Group of any claim or of the  commencement by any such
Person of any Action (collectively, a "Third Party Claim") with respect to which
an  Indemnifying  Party may be  obligated  to  provide  indemnification  to such
Indemnitee  pursuant  to  Section  4.2 or  4.3,  or any  other  Section  of this
Agreement  or any NCR  Ancillary  Agreement,  such  Indemnitee  shall  give such
Indemnifying Party written notice thereof within 20 days after becoming aware of
such Third Party Claim.  Any such notice shall describe the Third Party Claim in
reasonable detail.  Notwithstanding the foregoing, the failure of any Indemnitee
to give notice as provided in this Section  4.5(a) shall not relieve the related
Indemnifying  Party of its  obligations  under this  Article  IV,  except to the
extent that such  Indemnifying  Party is actually  prejudiced by such failure to
give notice.

                  (b) If the  Indemnitee  or any other  party to
this  Agreement
believes that the Third Party Claim is or may be a Shared
Contingent  Liability,
such  Indemnitee or other party may make a  Determination  Request in accordance
with the Separation and Distribution  Agreement at any time following any notice
given by the Indemnitee to an  Indemnifying  Party  pursuant to Section  4.5(a).
AT&T may make such a Determination Request at any time. Unless each of AT&T, NCR
and Lucent has acknowledged that the applicable Third Party Claim (including any
Third Party Claim set forth on Schedule 6.6 to the Separation  and  Distribution
Agreement) is not a Shared  Contingent  Liability or unless a  determination  to
such effect has been made in accordance  with the  Separation  and  Distribution
Agreement,  AT&T shall be entitled (but not  obligated) to assume the defense of
such Third Party Claim as if it were the Indemnifying  Party  hereunder.  In any
such  event,  AT&T  shall be  entitled  to  reimbursement  of all the  costs and
expenses (including  allocated costs of in-house counsel and other personnel) of
such  defense once a final  determination  or  acknowledgment  is made as to the
status of the Third Party Claim from the applicable  party or parties that would
have been  required  to pay such  amounts if the status of the Third Party Claim
had been  determined  immediately;  provided  that, if such Third Party Claim is
determined to be a Shared Contingent Liability, such costs and expenses shall be
shared  as  provided  in  Section  5.5(c)  of the  Separation  and  Distribution
Agreement.

                  (c) AT&T shall  assume the  defense of, and may seek to settle
or compromise,  any Third Party Claim that is a Shared Contingent Liability, and
the costs and expenses (including  allocated costs of in-house counsel and other
personnel)  thereof  shall be included in the  calculation  of the amount of the
applicable  Shared   Contingent   Liability  in  determining  the  reimbursement
obligations of the other parties with respect thereto pursuant to Section 6.4 of
the Separation and Distribution Agreement. Any Indemnitee in respect of a Shared
Contingent  Liability  shall have the right to employ  separate  counsel  and to
participate in (but not control) the defense, compromise, or settlement thereof,
but all  fees  and  expenses  of  such  counsel  shall  be the  expense  of such
Indemnitee.





<PAGE>

                  (d) Other than in the case of a Shared  Contingent  Liability,
an Indemnifying  Party may elect to defend (and,  unless the Indemnifying  Party
has specified any reservations or exceptions,  to seek to settle or compromise),
at such Indemnifying  Party's own expense and by such  Indemnifying  Party's own
counsel,  any Third Party Claim. Within 30 days after the receipt of notice from
an  Indemnitee in accordance  with Section  4.5(a) (or sooner,  if the nature of
such Third Party Claim so  requires),  the  Indemnifying  Party shall notify the
Indemnitee  of  its  election  whether  the   Indemnifying   Party  will  assume
responsibility  for  defending  such Third Party  Claim,  which  election  shall
specify any reservations or exceptions.  After notice from an Indemnifying Party
to an  Indemnitee  of its election to assume the defense of a Third Party Claim,
such  Indemnitee  shall  have  the  right  to  employ  separate  counsel  and to
participate in (but not control) the defense, compromise, or settlement thereof,
but the  fees  and  expenses  of  such  counsel  shall  be the  expense  of such
Indemnitee  except as set forth in the next sentence.  In the event that (i) the
Third Party Claim is not a Shared Contingent Liability and (ii) the Indemnifying
Party has  elected  to assume  the  defense  of the  Third  Party  Claim but has
specified,  and  continues to assert,  any  reservations  or  exceptions in such
notice, then, in any such case, the reasonable fees and expenses of one separate
counsel for all Indemnitees shall be borne by the Indemnifying Party.

                  (e) Other than in the case of a Shared  Contingent  Liability,
if an  Indemnifying  Party elects not to assume  responsibility  for defending a
Third Party Claim,  or fails to notify an Indemnitee of its election as provided
in Section 4.5(d), such Indemnitee may defend such Third Party Claim at the cost
and expense (including  allocated costs of in-house counsel and other personnel)
of the Indemnifying Party.

                  (f)  Unless  the  Indemnifying  Party has failed to assume the
defense of the Third Party Claim in accordance with the terms of this Agreement,
no  Indemnitee  may settle or  compromise  any Third  Party  Claim that is not a
Shared Contingent  Liability  without the consent of the Indemnifying  Party. No
Indemnitee  may  settle or  compromise  any Third  Party  Claim that is a Shared
Contingent Liability without the consent of AT&T.

                  (g) In the case of a Third  Party  Claim  that is not a Shared
Contingent  Liability,  no  Indemnifying  Party  shall  consent  to entry of any
judgment  or enter into any  settlement  of the Third  Party  Claim  without the
consent of the  Indemnitee  if the effect  thereof is to permit any  injunction,
declaratory  judgment,  other order or other  nonmonetary  relief to be entered,
directly or  indirectly,  against any  Indemnitee.  In the case of a Third Party
Claim that is a Shared Contingent Liability,  AT&T shall not consent to entry of
any judgment or enter into any  settlement  of the Third Party Claim without the
consent of the  Indemnitee  if the effect  thereof is to permit any  injunction,
declaratory  judgment,  other order or other  nonmonetary  relief to be entered,
directly or indirectly, against any Indemnitee.

                  (h) The  provisions  of Section  4.5 and Section 4.6 shall not
apply to Taxes (which are covered by the Tax Sharing Agreement).

                  4.6. ADDITIONAL MATTERS. (a) Any claim on
account of a
Liability which does not result from a Third Party Claim shall be
asserted by
written notice given by the Indemnitee to the related Indemnifying
Party. Such
Indemnifying Party shall have a period




<PAGE>

of 30 days after the receipt of such notice within which to respond thereto.  If
such  Indemnifying  Party does not  respond  within  such  30-day  period,  such
Indemnifying  Party shall be deemed to have refused to accept  responsibility to
make payment.  If such  Indemnifying  Party does not respond  within such 30-day
period or rejects such claim in whole or in part, such Indemnitee  shall be free
to pursue such remedies as may be available to such party as contemplated by any
Transaction Agreement.

                  (b)  In  the  event  of   payment  by  or  on  behalf  of  any
Indemnifying  Party to any Indemnitee in connection  with any Third Party Claim,
such  Indemnifying  Party shall be subrogated to and shall stand in the place of
such  Indemnitee  as to any  events or  circumstances  in  respect of which such
Indemnitee  may have any right,  defense or claim  relating  to such Third Party
Claim  against any  claimant or  plaintiff  asserting  such Third Party Claim or
against any other person. Such Indemnitee shall cooperate with such Indemnifying
Party in a reasonable manner,  and at the cost and expense (including  allocated
costs of in-house  counsel and other personnel) of such  Indemnifying  Party, in
prosecuting any subrogated right, defense or claim; provided, however, that AT&T
shall be entitled to control the prosecution of any such right, defense or claim
in respect of any Shared Contingent Liability.

                  (c) In the event of an Action in which the Indemnifying  Party
is not a named defendant,  if either the Indemnified Party or Indemnifying Party
shall so request,  the parties  shall  endeavor to substitute  the  Indemnifying
Party for the named defendant or, in the case of a Shared Contingent  Liability,
add the Indemnifying Party as a named defendant, if at all practicable.  If such
substitution  or addition cannot be achieved for any reason or is not requested,
the named defendant shall allow the  Indemnifying  Party to manage the Action as
set forth in this  Section  and,  subject to Section 6.4 of the  Separation  and
Distribution  Agreement  with  respect  to Shared  Contingent  Liabilities,  the
Indemnifying  Party shall fully indemnify the named defendant  against all costs
of defending the Action  (including court costs,  sanctions  imposed by a court,
attorneys'  fees,  experts'  fees  and  all  other  external  expenses,  and the
allocated  costs of  in-house  counsel  and other  personnel),  the costs of any
judgment or  settlement,  and the cost of any interest or penalties  relating to
any judgment or settlement.

                  4.7.  REMEDIES  CUMULATIVE.  The  remedies  provided  in  this
Article IV shall be cumulative  and,  subject to the provisions of Article IX of
the Separation and Distribution  Agreement,  shall not preclude assertion by any
Indemnitee  of any other  rights or the  seeking  of any and all other  remedies
against any Indemnifying Party.

                  4.8. SURVIVAL OF INDEMNITIES. The rights and
obligations of
each of AT&T and NCR and their respective Indemnitees under this
Article IV
shall  survive  the  sale or  other  transfer  by any  party  of any  Assets  or
businesses or the assignment by it of any Liabilities.

                  4.9. RELATIONSHIP TO SEPARATION AND DISTRIBUTION
AGREEMENT
DISPUTE RESOLUTION PROCEDURES. (a) Each of NCR and AT&T agrees
that the
procedures for discussion, negotiation and arbitration set forth
in Article IX
of the Separation and Distribution Agreement (which are hereby
incorporated
herein by reference) shall apply to all dis-




<PAGE>

putes, controversies or claims (whether sounding in contract, tort or otherwise)
that may arise out of or relate to, or arise  under or in  connection  with this
Agreement or, except as otherwise expressly provided therein,  any NCR Ancillary
Agreement (as if each of this Agreement and each of the NCR Ancillary Agreements
were an Ancillary Agreement), or the transactions contemplated hereby or thereby
(including  all actions taken in furtherance  of the  transactions  contemplated
hereby or thereby on or prior to the date hereof), or the commercial or economic
relationship  of the parties  relating  hereto or thereto,  between or among any
member of the AT&T Services Group and the NCR Group.

                  (b) Each party  agrees on behalf of itself and each  member of
its  respective  Group that the procedures set forth in such Article IX shall be
the sole and exclusive  remedy in connection  with any dispute,  controversy  or
claim relating to any of the foregoing matters and irrevocably  waives any right
to  commence  any  Action in or before  any  Governmental  Authority,  except as
expressly provided in Sections 9.7(b) and 9.8 of the Separation and Distribution
Agreement and except to the extent  provided  under the  Arbitration  Act in the
case of judicial review of arbitration  results or awards.  Each party on behalf
of itself and each member of its respective Group  irrevocably  waives any right
to any trial by jury with respect to any claim, controversy or dispute set forth
in  the  first  sentence  of  Section  9.1 of the  Separation  and  Distribution
Agreement.

                  (c) Without limiting the foregoing, each of the parties agrees
on behalf of itself and each member of its Group that if an  Arbitration  Demand
Notice with respect to a dispute, controversy or claim is not given prior to the
expiration of the Applicable  Deadline,  as between or among the parties and the
members of their Groups, such dispute, controversy or claim will be barred.

                  (d) Subject to Sections  9.7(d) and 9.8 of the  Separation and
Distribution  Agreement,  upon delivery of an Arbitration Demand Notice pursuant
to Section  9.3(a) of the  Separation and  Distribution  Agreement  prior to the
Applicable  Deadline,  the dispute,  controversy  or claim shall be decided by a
sole  arbitrator  in  accordance  with the rules set forth in  Article IX of the
Separation and Distribution Agreement.

                  (e) The  interpretation  of the provisions of this Section 4.9
and  Article IX of the  Separation  and  Distribution  Agreement  (to the extent
incorporated herein by reference),  only insofar as they relate to the agreement
to  arbitrate  and any  procedures  pursuant  thereto,  shall be governed by the
Arbitration Act and other  applicable  federal law. In all other  respects,  the
interpretation of this Agreement shall be governed as set forth in Section 8.2.


                                    ARTICLE V
                  INTERIM OPERATIONS AND CERTAIN OTHER MATTERS


                  5.1. CERTAIN TAX MATTERS. Notwithstanding any
other provision
of this Agreement, the Tax Sharing Agreement or any other
Transaction Agreement,
in the case of any Adjustment comprising a Restructuring
Adjustment that relates
to the NCR Distribution




<PAGE>

and arises as a result of the acquisition of all or a portion of the NCR capital
stock of any class or series and/or of its assets by any means whatsoever by any
Person other than an Affiliate of NCR following such NCR Distribution, NCR shall
indemnify,  defend  and  hold  harmless  AT&T  from  and  against  any  and  all
Liabilities  of  AT&T  relating  to,  arising  out  of or  resulting  from  such
Adjustment.

                  5.2. AGREEMENT FOR EXCHANGE OF INFORMATION;
ARCHIVES. Each of
AT&T and NCR agrees that the  provisions of Article VIII of the
Separation  and
Distribution  Agreement shall continue to apply after the NCR
Distribution Date;
provided however, that as between the members of NCR Group, on the one hand, and
the AT&T  Services  Group,  on the  other  hand,  the  reference  to "the  third
anniversary   of  the  date  hereof"  in  Section  8.2  of  the  Separation  and
Distribution  Agreement shall be deemed to be the third  anniversary of the date
of this  Agreement.  Without  limiting the foregoing,  (a) NCR shall maintain in
effect at its own cost and expense  adequate  systems and controls to the extent
necessary  to enable the members of the AT&T Group to satisfy  their  respective
reporting,  accounting,  audit and other obligations, and (b) NCR shall provide,
or cause to be  provided,  to AT&T in such  form as AT&T  shall  request,  at no
charge to AT&T, all financial and other data and  information as AT&T determines

                                   ARTICLE VI
                   FURTHER ASSURANCES AND ADDITIONAL COVENANTS

                  6.1.  FURTHER  ASSURANCES.  (a) In  addition  to  the  actions
specifically  provided  for  elsewhere  in this  Agreement,  each of the parties
hereto shall use its  reasonable  best  efforts,  prior to, on and after the NCR
Distribution  Date,  to take, or cause to be taken,  all actions,  and to do, or
cause to be done, all things,  reasonably  necessary,  proper or advisable under
applicable laws, regulations and agreements to consummate and make effective the
transactions contemplated by this Agreement and the NCR Ancillary Agreements.

                  (b) Without limiting the foregoing, prior to, on and after the
NCR Distribution Date, each party hereto shall cooperate with the other parties,
and  without  any further  consideration,  but at the expense of the  requesting
party, to execute and deliver, or use its reasonable best efforts to cause to be
executed and delivered,  all instruments,  including  instruments of conveyance,
assignment  and  transfer,  and to make all  filings  with,  and to  obtain  all
consents,  approvals or  authorizations  of, any  Governmental  Authority or any
other Person under any permit, license, agreement, indenture or other instrument
(including any Consents or Governmental  Approvals),  and to take all such other
actions as such party may  reasonably  be  requested  to take by any other party
hereto from time to time,  consistent  with the terms of this  Agreement and the
NCR Ancillary Agreements,  in order to effectuate the provisions and purposes of
this  Agreement  and the NCR  Ancillary  Agreements  and the other  transactions
contemplated  hereby and thereby.  Without  limiting the  foregoing,  each party
will, at the reasonable request,  cost and expense of any other party, take such
other actions as may be





<PAGE>

reasonably necessary to vest in such other party good and marketable title, free
and clear of any Security Interest, if and to the extent it is practicable to do
so.

                  (c) Each of AT&T and NCR, at the  request of the other,  shall
use its  reasonable  best  efforts to obtain,  or to cause to be  obtained,  any
consent, substitution,  approval or amendment required to novate (including with
respect to any federal  government  contract)  or assign all  obligations  under
agreements,  leases, licenses and other obligations or Liabilities of any nature
whatsoever  that  constitute  Liabilities of the NCR Group or  Liabilities  that
relate to the NCR Group,  or to obtain in writing the  unconditional  release of
all  parties to such  arrangements  other  than any member of the NCR Group,  so
that, in any such case, NCR and its Subsidiaries will be solely  responsible for
such  Liabilities;  provided,  however,  that  neither  AT&T  nor NCR  shall  be
obligated  to pay any  consideration  therefor to any third party from whom such
consents, approvals, substitutions, amendments and releases are requested.

                  (d) If AT&T or NCR is  unable  to  obtain,  or to  cause to be
obtained,  any  such  required  consent,  approval,  release,   substitution  or
amendment, the applicable member of the AT&T Services Group shall continue to be
bound by such agreements, leases, licenses and other obligations and, unless not
permitted by law or the terms thereof,  NCR shall, as agent or subcontractor for
AT&T or such other Person,  as the case may be, pay, perform and discharge fully
all the  obligations or other  Liabilities of AT&T or such other Person,  as the
case may be, thereunder from and after the date hereof. NCR shall indemnify each
AT&T Indemnitee,  and hold each of them harmless against any Liabilities arising
in connection therewith.

                  (e) On or prior to the Closing  Date,  AT&T and NCR shall take
all actions as may be  necessary  to approve the  stock-based  employee  benefit
plans of NCR in order to  satisfy  the  requirements  of Rule  16b-3  under  the
Exchange Act and Section 162(m) of the Code.

                  (f) The parties  hereto agree to take any  reasonable  actions
necessary  in  order  for  the  NCR   Distribution  to  qualify  as  a  tax-free
distribution pursuant to Section 355 of the Code.

                  6.2. QUALIFICATION AS TAX-FREE DISTRIBUTION. (a) After the NCR
Distribution  Date,  none of AT&T or NCR shall take, or permit any member of its
respective  Group to take,  any action  which  could  reasonably  be expected to
prevent the NCR Distribution from qualifying as a tax-free  distribution  within
the meaning of Section 355 of the Code or any other transaction  contemplated by
this  Agreement  or any other  Transaction  Agreement  which is  intended by the
parties to be tax-free from failing so to qualify.

                  (b) After the NCR Distribution  Date, NCR shall not, nor cause
or  permit,  any  member of the NCR Group to take any  action or enter  into any
transaction  which could  reasonably be expected to materially  adversely impact
the reasonably  expected tax  consequences to AT&T which are known to NCR of any
transaction  contemplated  by  this  Agreement  or  any  Transaction  Agreement;
provided,  however,  nothing in this section shall  prohibit NCR from taking any
action, or entering into any transaction (or permitting or causing any member of
the NCR Group so to act or enter) in the  ordinary  course of business or in the
ordinary course of business dealing, or in connection with the settlement of any
audit issue or in  connection  with the filing of any tax return.  After the NCR
Distribution  Date, AT&T shall not, nor cause or permit,  any member of the AT&T
Group to take any action or enter into any transaction which could reasonably be
expected to materially  adversely  impact the expected tax  consequences  to NCR
which are known to AT&T of any transaction contemplated by this Agreement or any
Transaction Agreement; provided, however, nothing in this section shall prohibit
AT&T from taking any action,  or entering into any transaction (or permitting or
causing any member of the AT&T Group so to act or enter), in the ordinary course
of business or in the ordinary course of business dealing, or in connection with
the  settlement of any audit issue or in  connection  with the filing of any tax
return.

that would violate its fiduciary duties to any minority  stockholders of Lucent,
AT&T Capital  Corporation or any other  non-wholly  owned Subsidiary of AT&T (it

NCR Ancillary Agreement or the application thereof to any Person or circumstance
is  determined  by a court of  competent  jurisdiction  to be  invalid,  void or
unenforceable, the remaining provisions hereof or thereof, or the application of
such provision to Persons or circumstances or in jurisdictions  other than those
as to which it has been held  invalid  or  unenforceable,  shall  remain in full
force  and  effect  and shall in no way be  affected,  impaired  or  invalidated
thereby,  so  long  as the  economic  or  legal  substance  of the  transactions
contemplated  hereby  or  thereby,  as the case may be, is not  affected  in any
manner  adverse  to any  party.  Upon  such  determination,  the  parties  shall
negotiate in good faith in an effort to agree upon such a suitable and equitable

                  8.7.  FORCE  MAJEURE.  No party  shall be deemed in default of
this  Agreement or any NCR  Ancillary  Agreement to the extent that any delay or

without its fault or negligence,  such as acts of God, acts of civil or military
authority, embargoes,  epidemics, war, riots, insurrections,  fires, explosions,
earthquakes,  floods,  unusually  severe weather  conditions,  labor problems or
unavailability  of parts,  or, in the case of computer  systems,  any failure in
electrical  or air  conditioning  equipment.  In the  event of any such  excused
delay, the time for performance shall be extended for a period equal to the time
lost by reason of the delay.

                  8.8.  PUBLICITY.  Prior to the NCR Distribution  Date, each of
NCR and AT&T shall  consult with each other prior to issuing any press  releases

hereby and prior to making any  filings  with any  Governmental  Authority  with
respect thereto.

                  8.9. EXPENSES. Except as expressly set forth in this Agreement
or in any NCR  Ancillary  Agreement,  whether  or not the  NCR  Distribution  is
consummated,  all third party fees, costs and expenses paid or incurred prior to
the NCR Distribution  Date in connection with the NCR Distribution  will be paid
by AT&T;  provided  however that NCR shall  consult with AT&T prior to incurring
any such third party obligations.

paragraph headings
contained in this Agreement and in the NCR Ancillary Agreements
are for

set forth in
any NCR Ancillary Agreement, the covenants, representations and
warranties
contained in this Agreement and each NCR Ancillary Agreement, and
liability for

contained  herein,  shall survive the NCR  Distribution and shall remain in full
force and effect following the consummation of the NCR Distribution.

                  8.12.  WAIVERS OF DEFAULT.  Waiver by any party of any default
by the other  party of any  provision  of this  Agreement  or any NCR  Ancillary
Agreement shall not be deemed a waiver by the waiving party of any subsequent or
other default, nor shall it prejudice the rights of the other party.

                  8.13.  AMENDMENTS.  No provisions of this Agreement or any NCR
Ancillary Agreement shall be deemed waived, amended, supplemented or modified by
any party,  unless such waiver,  amendment,  supplement  or  modification  is in

                              TAX SHARING AGREEMENT

                  THIS TAX SHARING  AGREEMENT,  dated as of February 1, 1996, is
by and among AT&T, Lucent and NCR.  Capitalized terms used herein shall have the
respective  meanings  assigned  to  them  in  the  Separation  Agreement  unless
otherwise defined in Article I hereof.

                  WHEREAS,  AT&T,  Lucent and NCR have  executed the  Separation
Agreement  pursuant to which AT&T's  existing  businesses will be separated into
three independent businesses; and

                  WHEREAS,  it is  appropriate  and  desirable  to set forth the
principles  and  responsibilities  of the  parties to this  Agreement  regarding
future  Adjustments  with respect to Taxes,  Tax Contests and other  related Tax
matters.

                  NOW,  THEREFORE,  the parties,  intending to be
legally bound,
agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

                  For the purpose of this  Agreement the  following  terms shall
have the following meanings:

                  1.1.  ADJUSTMENT  means the deemed  increase  or
decrease in a
Tax,  determined on an  issue-by-issue or
transaction-by-transaction  basis, as
appropriate, and using the assumptions set forth in the next sentence, resulting
from an adjustment  made or proposed by a Taxing  Authority  with respect to any
amount reflected or required to be reflected on any Return relating to such Tax.
For  purposes  of  determining  such deemed  increase or decrease in a Tax,  the
following  assumptions  will be used:  (a) in the case of any  income  Tax,  the
highest  marginal  Tax  rate or,  in the  case of any  other  Tax,  the  highest
applicable  Tax rate,  in each case in effect  with  respect to that Tax for the
Taxable  period or any  portion of the  Taxable  period to which the  adjustment
relates;  and (b) such determination shall be made without regard to whether any
actual increase or decrease in such Tax will in fact be realized with respect to
the Return to which such adjustment relates.

                  (ii)  second,  the  Net  Restructuring   Adjustment  shall  be
allocated  among  AT&T,  Lucent  and  NCR  in  proportion  to  the  Shared  AT&T
Percentage, the Shared Lucent Percentage and the Shared
NCR  Percentage,
respectively,  to the  extent  each  such  party is  liable  for  and/or  has an
obligation  to make,  or has the  right  to  receive,  as the  case may be,  any
indemnity  payment,   reimbursement  or  other  payment  with  respect  to  such
Restructuring Adjustment under this Agreement; and

                  (iii) finally,  with respect to a party to which a Correlative
Adjustment  is  attributable,  that  party's  share  of  the  Net  Restructuring
Adjustment as allocated  pursuant to paragraph  (ii) of this Section 2.3(d) will
be  increased  or  decreased,  as  appropriate,  by the  amount,  if any, of the
Correlative  Adjustment that is attributable to such party in order to arrive at
such party's share of the Restructuring Adjustment.

Notwithstanding  any  other  provision  of  this  Agreement  or  the  Separation
Agreement  to  the  contrary,  in  the  case  of  any  Adjustment  comprising  a
Restructuring Adjustment that relates to the Distribution and arises as a result
of the  acquisition of all or a portion of the Lucent stock and/or its assets by
any means  whatsoever by any Person other than an Affiliate of Lucent  following
such  Distribution,  then the  Shared  Lucent  Percentage  with  respect to such
Adjustment  shall be 100% and each of the Shared AT&T  Percentage and the Shared
NCR Percentage shall be 0%.

                  (e)  Following  the  determination  of a  party's  share  of a
Restructuring  Adjustment  pursuant  to Section  2.3(d)  above,  and  subject to
Section 3.4 and 3.5 hereof,  the Controlling Party that controls the Tax Contest
to  which  such  Restructuring  Adjustment  relates  shall  (i) be  entitled  to
reimbursement  from AT&T,  Lucent  and/or  NCR,  as the case may be, for each of
their respective  shares, if any, of any Restructuring  Adjustment the amount of
which increases a Tax; and (ii) reimburse  AT&T,  Lucent or NCR, as the case may
be, for each of their respective shares, if any, of any Restructuring Adjustment
the amount of which decreases a Tax.

                  2.4.  NON-LINE OF BUSINESS  ADJUSTMENTS.  (a) Lucent  shall be
liable for, and shall indemnify and hold harmless, as appropriate, any member of

amount of which  increases a Tax for any Taxable  period or portion of a Taxable
period ending or deemed to end on or before the Distribution  Date, in each case
with respect to any Return of any member of the Lucent Group,  the AT&T Services
Group or the NCR Group.  Lucent shall be entitled to receive,  and shall be paid
(i) by AT&T,  Lucent's  share,  as  determined in Section  2.4(d) below,  of any
Non-Line  of  Business  Adjustment  the amount of which  decreases a Tax for any
Taxable  period or  portion  of a Taxable  period  ending or deemed to end on or
before the Distribution Date with respect to any Return of any member of the



<PAGE>

AT&T  Services  Group;  and/or (ii) by NCR,  Lucent's  share,  as  determined in

deemed to end on or before the  Distribution  Date with respect to any Return of
any member of the NCR Group.

                  (b) AT&T shall be liable  for,  and shall  indemnify  and hold
harmless,  as  appropriate,  (i) any member of the Lucent Group  against  AT&T's
share,  as  determined  in Section  2.4(d)  below,  of any  Non-Line of Business
Adjustment the amount of which increases a Tax for any Taxable period or portion
of a Taxable period ending or deemed to end on or before the Distribution  Date;
and (ii) any member of the NCR Group  against  AT&T's  share,  as  determined in

deemed to end on or before the date of the NCR  Distribution,  in each case with
respect to any Return of any member of the Lucent Group, the AT&T Services Group
or the NCR Group.  AT&T shall be entitled  to receive,  and shall be paid (i) by
Lucent,  AT&T's share, as determined in Section 2.4(d) below, of any Non-Line of
Business  Adjustment the amount of which  decreases a Tax for any Taxable period
or  portion  of a Taxable  period  ending  or  deemed  to end on or  before  the
Distribution  Date with respect to any Return of any member of the Lucent Group;
and/or (ii) by NCR,  AT&T's share, as determined in Section 2.4(d) below, of any

before the date of the NCR Distribution with respect to any Return of any member
of the NCR Group.

                  (c) NCR shall be liable  for,  and  shall  indemnify  and hold
harmless,  as  appropriate,  (i) any member of the Lucent  Group  against  NCR's

Adjustment the amount of which increases a Tax for any Taxable period or portion
of a Taxable period ending or deemed to end on or before the Distribution  Date;
and  (ii)  any  member  of the AT&T  Services  Group  against  NCR's  share,  as
determined in Section 2.4(d) below,  of any Non-Line of Business  Adjustment the
amount of which  increases a Tax for any Taxable  period or portion of a Taxable
period ending or deemed to end on or before the date of the NCR Distribution, in
each case with respect to any Return of any member of the Lucent Group, the AT&T
Services Group or the NCR Group. NCR shall be entitled to receive,  and shall be
paid (i) by Lucent,  NCR's share,  as determined in Section 2.4(d) below, of any
Non-Line  of  Business  Adjustment  the amount of which  decreases a Tax for any
Taxable  period or  portion  of a Taxable  period  ending or deemed to end on or
before  the  Distribution  Date with  respect to any Return of any member of the
Lucent Group;  and/or (ii) by AT&T, NCR's share, as determined in Section 2.4(d)
below,  of any Non-Line of Business  Adjustment the amount of which  decreases a
Tax for any Taxable



<PAGE>

period or portion of a Taxable  period  ending or deemed to end on or before the
date of the NCR  Distribution  with  respect  to any Return of any member of the
AT&T Services Group.

                  (d)  AT&T,  Lucent  and NCR  shall  share  the  amount  of any
Non-Line of Business Adjustment if, and to the extent, each such party is liable
for and/or has an obligation  to make, or has the right to receive,  as the case
may be, any indemnity  payment,  reimbursement  or other payment with respect to
such Non-Line of Business Adjustment under this Agreement,  in proportion to the
Shared  AT&T  Percentage,  the  Shared  Lucent  Percentage  and the  Shared  NCR
Percentage, respectively; provided, however, that in the event that there is any
Correlative Adjustment with respect to any such Non-Line of Business Adjustment,
then AT&T,  Lucent and NCR shall share such  Non-Line of Business  Adjustment in
the following manner in order to ensure that the party or parties that will bear
the burden or inure to the benefit of the  Correlative  Adjustment in the future
will share the Non-Line of Business  Adjustment  in  proportion to each of their
respective   Shared   Percentages   after  giving  effect  to  such  Correlative
Adjustment:

                  (i)  first,  the  amount  of any  such  Non-Line  of  Business
Adjustment shall be increased or decreased, as appropriate, by the amount of the
Correlative Adjustment,  the net amount resulting from such increase or decrease
being hereinafter  referred to as the "Net Non-Line of Business  Adjustment" for
purposes of this Section 2.4(d);

                  (ii) second, the Net Non-Line of Business  Adjustment shall be
allocated  among  AT&T,  Lucent  and  NCR  in  proportion  to  the  Shared  AT&T
Percentage, the Shared Lucent Percentage and the Shared
NCR  Percentage,
respectively,  to the  extent  each  such  party is  liable  for  and/or  has an
obligation  to make,  or has the  right  to  receive,  as the  case may be,  any
indemnity payment,  reimbursement or other payment with respect to such Non-Line
of Business Adjustment under this Agreement; and

                  (iii) finally,  with respect to a party to which a Correlative
Adjustment is  attributable,  that party's share of the Net Non-Line of Business
Adjustment as allocated  pursuant to paragraph  (ii) of this Section 2.4(d) will
be  increased  or  decreased,  as  appropriate,  by the  amount,  if any, of the
Correlative  Adjustment that is attributable to such party in order to arrive at
such party's share of the Non-Line of Business Adjustment.

                  (e)  Following  the  determination  of a  party's  share  of a
Non-Line of Business Adjustment pursuant to Section 2.4(d) above, and subject to
Section 3.4 and 3.5 hereof,  the Controlling Party that controls the Tax Contest
to which such Non-Line of Business  Adjustment  relates shall (i) be entitled to
reimbursement from AT&T, Lucent



<PAGE>

and/or NCR, as the case may be, for each of their respective  shares, if any, of
any  Non-Line of Business  Adjustment  the amount of which  increases a Tax; and
(ii)  reimburse  AT&T,  Lucent  or NCR,  as the case  may be,  for each of their
respective shares, if any, of any Non-Line of Business  Adjustment the amount of
which decreases a Tax.

                                   ARTICLE III
                                  TAX CONTESTS

                  3.1. NOTIFICATION OF TAX CONTESTS. The Controlling Party shall
promptly  notify  all  Interested  Parties  of (a) the  commencement  of any Tax
Contest  pursuant  to which such  Interested  Parties may be required to make or
entitled to receive an indemnity  payment,  reimbursement or other payment under
this  Agreement;  and (b) as required and  specified in Section 3.4 hereof,  any
Final  Determination made with respect to any Tax Contest pursuant to which such
Interested  Parties may be required to make or entitled to receive any indemnity
payment,  reimbursement or other payment under this Agreement.  The failure of a
Controlling  Party to promptly  notify any Interested  Party as specified in the
preceding  sentence shall not relieve any such Interested Party of any liability
and/or  obligation  which  it may  have  to the  Controlling  Party  under  this
Agreement  except to the extent that the Interested Party was prejudiced by such
failure,  and in no event shall such failure  relieve the Interested  Party from
any other liability or obligation which it may have to such Controlling Party.

                  3.2. TAX CONTEST  SETTLEMENT  RIGHTS.  The  Controlling  Party
shall  have the sole  right to  contest,  litigate,  compromise  and  settle any
Adjustment that is made or proposed in a Tax Contest without obtaining the prior
consent of any Interested Party;  provided,  however, that, unless waived by the
parties in writing, the Controlling Party shall, in connection with any proposed
or assessed  Adjustment  in a Tax Contest for which an  Interested  Party may be
required to make or entitled to receive an indemnity  payment,  reimbursement or
other payment under this Agreement (a) keep all such Interested Parties informed
in a  timely  manner  of all  actions  taken  or  proposed  to be  taken  by the
Controlling  Party;  and (b) provide all such Interested  Parties with copies of
any  correspondence  or filings  submitted  to any Taxing  Authority or judicial
authority, in each case in connection with any contest,  litigation,  compromise
or settlement relating to any such Adjustment in a Tax Contest. The failure of a
Controlling Party to take any action as specified in the preceding sentence with
respect to an Interested  Party shall not relieve any such  Interested  Party of
any liability and/or obligation which it may have to the Controlling Party under
this Agreement  except to the extent that the Interested Party was prejudiced by
such failure,  and in no event shall such failure  relieve the Interested  Party
from any other  liability or  obligation  which it may have to such  Controlling
Party. The Controlling Party may, in its sole discretion,  take into account any
suggestions made by



<PAGE>

an Interested Party with respect to any such contest, litigation,  compromise or
settlement of any Adjustment in a Tax Contest.  All costs of any Tax Contest are
to be borne by the  Controlling  Party;  provided,  however,  that (x) any costs
related  to an  Interested  Party's  attendance  at any  meeting  with a  Taxing
Authority or hearing or  proceeding  before any judicial  authority  pursuant to
Section  3.3  hereof,  and (y) the costs of any  legal or other  representatives
retained by an  Interested  Party in  connection  with any Tax  Contest  that is
subject to the provisions of this  Agreement,  shall be borne by such Interested
Party.

                  3.3.  TAX  CONTEST  PARTICIPATION.  (a)  Unless  waived by the
parties in writing, the Controlling Party shall provide an Interested Party with
written notice  reasonably in advance of, and such  Interested  Party shall have
the right to attend,  any formally scheduled meetings with Taxing Authorities or
hearings or proceedings  before any judicial  authorities in connection with any
contest,  litigation,  compromise  or  settlement  of any  proposed  or assessed
Adjustment  comprising  any Tax Adjustment or Tax Benefit that is the subject of
any Tax Contest  pursuant to which such Interested Party may be required to make
or entitled to receive an  indemnity  payment,  reimbursement  or other  payment
under this Agreement. In addition,  unless waived by the parties in writing, the
Controlling  Party shall provide each such Interested Party with draft copies of
any  correspondence  or  filings to be  submitted  to any  Taxing  Authority  or
judicial  authority with respect to such Adjustments for such Interested Party's
review and  comment.  The  Controlling  Party shall  provide  such draft  copies
reasonably  in advance of the date that they are to be  submitted  to the Taxing
Authority  or judicial  authority  and the  Interested  Party shall  provide its
comments,  if any, with respect  thereto within in a reasonable time before such
submission.   The  failure  of  a  Controlling  Party  to  provide  any  notice,
correspondence  or filing as specified in this Section  3.3(a) to an  Interested
Party  shall not  relieve  any such  Interested  Party of any  liability  and/or
obligation  which it may have to the  Controlling  Party  under  this  Agreement
except to the extent that the  Interested  Party was prejudiced by such failure,
and in no event shall such failure  relieve the Interested  Party from any other
liability or obligation which it may have to such Controlling Party.

                  (b) Unless waived by the parties in writing,  the  Controlling
Party shall  provide an  Interested  Party with  written  notice  reasonably  in
advance  of, and such  Interested  Party  shall  have the right to  attend,  any
formally  scheduled  meetings with Taxing Authorities or hearings or proceedings
before any judicial  authorities  in  connection  with any contest,  litigation,
compromise or settlement of any proposed or assessed  Adjustment  comprising any
Restructuring  Adjustment or Non-Line of Business Adjustment that is the subject
of any Tax Contest  pursuant to which such  Interested  Party may be required to
make or entitled to receive an indemnity payment, reimbursement or other payment
under this  Agreement,  but only if the Interested  Party bears,  or in the good
faith judgment of the Controlling Party, may bear, a Significant Obligation with
respect to such Adjustment;  provided,  however, that the Controlling Party may,
in its sole



<PAGE>

discretion,  permit an Interested Party that does not bear, or potentially bear,
such a Significant  Obligation  with respect to such an Adjustment  comprising a
Restructuring  Adjustment or Non-Line of Business  Adjustment to attend any such
meetings,  hearings or proceedings that relate to such Adjustment.  In addition,
unless  waived by the parties in writing,  the  Controlling  Party shall provide
each such Interested Party with draft copies of any correspondence or filings to
be submitted to any Taxing Authority or judicial  authority with respect to such
Adjustments  for such  Interested  Party's review and comment.  The  Controlling
Party shall  provide  such draft copies  reasonably  in advance of the date that
they are to be submitted to the Taxing  Authority or judicial  authority and the
Interested Party shall provide its comments, if any, with respect thereto within
in a reasonable time before such submission.  The failure of a Controlling Party
to provide any notice,  correspondence  or filing as  specified  in this Section
3.3(b) to an Interested Party shall not relieve any such Interested Party of any
liability  and/or  obligation  which it may have to the Controlling  Party under
this Agreement  except to the extent that the Interested Party was prejudiced by
such failure,  and in no event shall such failure  relieve the Interested  Party
from any other  liability or  obligation  which it may have to such  Controlling
Party.

                  3.4.  TAX  CONTEST  WAIVER.  (a) The
Controlling  Party shall
promptly  provide  written  notice,  sent postage prepaid by United States mail,
certified mail,  return receipt  requested,  to all Interested  Parties in a Tax
Contest (i) that a Final  Determination  has been made with  respect to such Tax
Contest; and (ii) enumerating the amount of the Interested Party's share of each
Adjustment  reflected in such Final  Determination  of the Tax Contest for which
such  Interested  Party  may be  required  to make or  entitled  to  receive  an
indemnity payment, reimbursement or other payment under this Agreement.

                  (b) Within ninety (90) days after an Interested Party receives
the notice described in Section 3.4(a) hereof from the Controlling  Party,  such
Interested  Party  shall  execute  a  written  statement  giving  notice  to the
Controlling Party (i) that the Interested Party agrees with each Adjustment (and
its share thereof)  enumerated in the notice  described in Section 3.4(a) hereof
except with respect to those  Adjustments  (and/or its shares  thereof) that, in
the good faith  judgment of the  Interested  Party,  it  disagrees  with and has
specifically  enumerated  its  disagreement  with,  including the amount of such
disagreement,  in the statement  (each such disagreed  Adjustment  (and/or share
thereof) hereinafter referred to as a "Disputed Adjustment");  and (ii) that the
Interested  Party thereby waives it right to a  determination  by an Independent
Third Party pursuant to the provisions of Section 3.5 hereof with respect to all
Adjustments  to which it  agrees  with its  share  (this  statement  hereinafter
referred to as the  "Interested  Party  Notice").  The failure of an  Interested
Party to provide the Interested Party Notice to the Controlling Party within the
ninety (90) day period  specified in the preceding  sentence  shall be deemed to
indicate that such Interested Party agrees with its share of all Adjustments



<PAGE>

enumerated  in the  notice  described  in  Section  3.4(a)  hereof and that such
Interested  Party waives it right to a  determination  by an  Independent  Third
Party with respect to all such Adjustments (and its shares thereof)  pursuant to
Section 3.5 hereof.

                  (c) During the ninety  (90) day period  immediately  following
the  Controlling  Party's  receipt of the Interested  Party Notice  described in
Section 3.4(b) above,  the Controlling  Party and the Interested  Party shall in
good faith confer with each other to resolve any disagreement over each Disputed
Adjustment that was specifically  enumerated in such Interested Party Notice. At
the end of the  ninety  (90) day period  specified  in the  preceding  sentence,
unless otherwise  extended in writing by the mutual consent of the parties,  the
Interested  Party shall be deemed to agree with all  Disputed  Adjustments  that
were specifically  enumerated in the Interested Party Notice and waive its right
to a determination by an Independent  Third Party pursuant to Section 3.5 hereof
with respect to all such Disputed Adjustments unless, and to the extent, that at
any  time  during  such  ninety  (90)  day  (or  extended)  period,  either  the
Controlling  Party or the  Interested  Party has given the other  party  written
notice that it is seeking a determination by an Independent Third Party pursuant
to Section 3.5 hereof regarding the propriety of any such Disputed Adjustment.

                  (d)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  an Interested Party that does not have a Significant  Obligation with
respect  to an  Adjustment  comprising  either  a  Restructuring  Adjustment  or
Non-Line  of  Business  Adjustment  has  no  right  to  a  determination  by  an
Independent  Third  Party  under  section  3.5 hereof  with  respect to any such
Adjustment  comprising  a  Restructuring  Adjustment  or  Non-Line  of  Business
Adjustment.

                  3.5.  TAX CONTEST  DISPUTE  RESOLUTION.  (a) In the event that
either a  Controlling  Party or an  Interested  Party has given the other  party
written  notice as  required  in  Section  3.4(c)  hereof  that it is  seeking a
determination  by an  Independent  Third Party pursuant to this Section 3.5 with
respect to any Disputed  Adjustment  that was enumerated in an Interested  Party
Notice,  then the parties shall, within ten (10) days after a party has received
such  notice,   jointly  select  an   Independent   Third  Party  to  make  such
determination.  In the  event  that  the  parties  cannot  jointly  agree  on an
Independent  Third  Party to make such  determination  within  such ten (10) day
period,  then  the  Controlling  Party  and  the  Interested  Party  shall  each
immediately  select an Independent Third Party and the Independent Third Parties
so selected by the parties shall jointly  select,  within ten (10) days of their
selection, another Independent Third Party to make such determination.

                  (b) In making its  determination  as to the  propriety  of any
Disputed  Adjustment,  the Independent  Third Party selected pursuant to Section
3.5(a) above shall assume that the Interested  Party is not required or entitled
under applicable law to be a



<PAGE>

member of any  Consolidated  Return.  In addition,  the Independent  Third Party
shall make its determination according to the following procedure:

                  (i) The  Independent  Third  Party shall  first  analyze  each
Disputed Adjustment for which a determination is sought pursuant to this Section
3.5 on a stand alone basis to determine  whether the actual outcome reached with
respect to such Disputed  Adjustment as reflected in the Final  Determination of
the Tax  Contest was fair and  appropriate  taking  into  account the  following
exclusive  criteria:  (A)  the  facts  relating  to  such  Adjustment;  (B)  the
applicable law, if any, with respect to such Adjustment; (C) the position of the
applicable Taxing Authority with respect to compromise, settlement or litigation
of such Adjustment;  (D) the strength of the factual and legal arguments made by
the Controlling Party in reaching the outcome with respect to such Adjustment as
reflected in the Final Determination of the Tax Contest; and (E) the strength of
the  factual  and legal  arguments  being made by the  Interested  Party for the
alternative  outcome being  asserted by such  Interested  Party  (including  the
availability of facts, information and documentation to support such alternative
outcome).  Based on this analysis,  the Independent  Third Party shall determine
what  is the  fair  and  appropriate  outcome  (hereinafter  referred  to as the
"Initial Determination") with respect to each such Disputed Adjustment.

                  (ii)  The   Interested   Party   shall  not  be   entitled  to
modification of its share of a Disputed Adjustment under this Section 3.5 if, as
the case may be,  either  (A) the amount  that  would be paid by the  Interested
Party under the Initial  Determination with respect to such Disputed  Adjustment
is 80% or more than the amount that would be paid by the  Interested  Party with
respect to such  Disputed  Adjustment  under the  actual  outcome  reached  with
respect to such Disputed Adjustment; or (B) the amount that would be received by
the  Interested  Party  under the  Initial  Determination  with  respect to such
Disputed  Adjustment is 120% or less than the amount that the  Interested  Party
would receive with respect to such Disputed  Adjustment under the actual outcome
reached with respected to such Disputed Adjustment.  The Independent Third Party
will provide notice to the  Controlling  Party and the  Interested  Party in the
event the Interested  Party is not entitled to  modification of its share of the
Disputed Adjustment pursuant to this paragraph (ii).

                  (iii) If the modification of an Interested  Party's share of a
Disputed  Adjustment  under  this  Section  3.5 is not  prohibited  pursuant  to
paragraph (ii) above,  then the Independent  Third Party shall determine what is
the fair and  appropriate  outcome  (hereinafter  referred  to as the  "Ultimate
Determination") to the Interested Party with respect to such Disputed Adjustment
in the context of the entire Tax Contest as it relates to the Interested  Party.
In making this  determination,  the  Independent  Third Party shall consider the
Disputed Adjustment as if it were raised in an independent audit of the



<PAGE>

Interested Party by the appropriate  Taxing Authority and the Independent  Third
Party shall take into account and give appropriate weight in its sole discretion
to the following exclusive  criteria:  (A) the strength of the legal and factual
support for other potential,  non-frivolous  Adjustments with respect to matters
that were actually  raised and contested by the applicable  Taxing  Authority in
the Tax Contest for which the Interested Party could have been liable under this
Agreement but which were  eliminated  or reduced as a result of the  Controlling
Party   agreeing  to  the  Disputed   Adjustment   as  reflected  in  the  Final
Determination  of the Tax Contest;  (B) the effect of the actual outcome reached
with respect to the Disputed  Adjustment on other  Taxable  periods and on other
positions taken or proposed to be taken in Returns filed or proposed to be filed
by the Interested Party; (C) the realistic  possibility of avoiding  examination
of  potential,  non-frivolous  issues for which the  Interested  Party  could be
liable  under  this  Agreement  and that were  contemporaneously  identified  in
writings by the party or parties  during the course of the Tax Contest but which
had not been raised and contested by the applicable  Taxing Authority in the Tax
Contest;  and (D) the  benefits  to the  Interested  Party in  reaching  a Final
Determination,  and the strategy and  rationale  with respect to the  Interested
Party's Disputed  Adjustment that the Controlling Party had for agreeing to such
Disputed Adjustment in reaching the Final Determination,  in each case that were
contemporaneously  identified  in  writings  by the party or parties  during the
course of the Tax Contest.

                  (iv)  The   Interested   Party   shall  only  be  entitled  to
modification of its share of a Disputed Adjustment under this Section 3.5 if, as
the case may be,  either  (A) the amount  that  would be paid by the  Interested
Party under the Ultimate  Determination with respect to such Disputed Adjustment
is less than 80% of the amount that would be paid by the  Interested  Party with
respect to such  Disputed  Adjustment  under the  actual  outcome  reached  with
respect to such Disputed Adjustment; or (B) the amount that would be received by
the  Interested  Party under the  Ultimate  Determination  with  respect to such
Disputed  Adjustment is more than 120% of the amount that the  Interested  Party
would receive with respect to such Disputed  Adjustment under the actual outcome
reached with respected to such Disputed  Adjustment.  If an Interested  Party is
entitled  to  modification  of its share of any  Disputed  Adjustment  under the
preceding  sentence,  the amount the Interested Party is entitled to receive, or
is required to pay, as the case may be, with respect to such Disputed Adjustment
shall be equal to the  amount of the  Ultimate  Determination  of such  Disputed
Adjustment.  The Independent  Third Party will provide notice to the Controlling
Party and the Interested  Party stating whether the Interested Party is entitled
to  modification  of its  share  of the  Disputed  Adjustment  pursuant  to this
paragraph  (iv) and, if the Interested  Party is entitled to such  modification,
the amount as determined in the preceding  sentence that the Interested Party is
entitled to receive  from,  or required  to pay to, the  Controlling  Party with
respect to such Disputed Adjustment.

                  (b) If after  (i)  notice  of a Final  Determination  of a Tax
Contest as required and  specified in Section  3.4(a) hereof has been given by a

                  (D) provided the Interested  Party Notice specified in Section
3.4(b)  hereof  within the ninety (90) day period  specified  in Section  3.4(b)

for  which  the  notice  specified  in  either  Section  3.5(b)(ii)  or  Section
3.5(b)(iv) hereof relating to any such Disputed  Adjustment has been given by an

indemnification,  reimbursement  or other  payment is sought (the  "Indemnifying
Party") of its right to and the amount of such indemnification, reimbursement or
other payment;  provided,  however,  that the failure to notify the Indemnifying
Party  shall not  relieve  the  Indemnifying  Party  from any  liability  and/or
obligation  which  it  may  have  to an  Indemnified  Party  on  account  of the
provisions   contained  in  this  Agreement   except  to  the  extent  that  the
Indemnifying  Party was  prejudiced by such failure,  and in no event shall such
failure  relieve the  Indemnifying  Party from any other liability or obligation
which it may have to such Indemnified  Party. The Indemnifying  Party shall make
such indemnity payment,  reimbursement or other payment to the Indemnified Party
within  thirty (30) days of the receipt of the written  notice  specified in the
preceding sentence.

Indemnifying  Party
to an Indemnified Party shall be made, at the option of the
Indemnifying  Party,
by (a) certified  check payable to the order of the  Indemnified  Party;  or (b)
wire transfer of immediately  available  funds to such bank and/or other account
of the Indemnified  Party as from time to time the Indemnified  Party shall have
directed the Indemnifying Party, in writing.

reimbursement or other
payment required to be made by an Interested Party pursuant to

CONSOLIDATION. It is
understood and agreed that during Consolidation:

                  (a) Members of the Lucent  Group and members of the NCR Group,
respectively,  shall each adopt and follow the Tax policies and procedures  that
have been  established by AT&T and  communicated to Lucent and NCR unless,  AT&T
shall otherwise  consent,  as provided herein. In the event that a member of the
Lucent  Group  and/or the NCR Group  desires to adopt and follow a Tax policy or
procedure that is different from that established by AT&T, Lucent and/or NCR, as
the case may be, shall,  in writing,  (i) request  AT&T's  consent to do so; and
(ii)  provide  AT&T with the  reasons  for the  request to adopt and follow such
different Tax policy or procedure. If AT&T determines in its good faith judgment
that it would be reasonable  and  appropriate  from the  perspective of the AT&T
Services Group for such member of the Lucent Group and/or the NCR Group to adopt
and follow  such  different  Tax policy or  procedure,  AT&T shall  provide  its
written consent thereto.

                  (b) AT&T shall provide to Lucent and NCR timely written notice
of any material proposed change in established Tax policies or procedures.

such Tax elections relating to a Consolidated  Return as may be taken or made by
AT&T,  or as  reasonably  requested by AT&T to be taken or made by any member of
the Lucent Group and/or any member of the NCR Group,  as the case may be, unless
AT&T shall  otherwise  consent,  as  provided  herein.  In the event that Lucent
and/or NCR determines that it would be reasonable and appropriate for any member
of the  Lucent  Group or any  member  of the NCR  Group,  respectively,  to take
positions or make elections relating to a Consolidated Return that are different
from those taken or made by AT&T (or reasonably  requested by AT&T of any member
of the Lucent Group or any member of the NCR Group),  Lucent  and/or NCR, as the
case may be, shall, in writing,



<PAGE>

(i) request  AT&T's consent to do so; and (ii) provide AT&T with the reasons for
the request to take such different  positions or make such different  elections.
If AT&T  determines in its good faith  judgment that it would be reasonable  and
appropriate  from the  perspective of the AT&T Services Group for such member of
the Lucent Group and/or the NCR Group to take such  different  positions or make
such different elections, AT&T shall provide its written consent thereto.

                  5.2.  COOPERATION.   Except  as  otherwise  provided  in  this
Agreement,  and without limiting the provisions contained in Article VIII of the
Separation  Agreement  which are  incorporated  herein by reference  pursuant to
Section 6.3(a) hereof,  each member of the AT&T Services Group, the Lucent Group
and/or the NCR Group, as the case may be, shall, at their own expense, cooperate
with each other in the filing of, or any Tax Contest relating to, any Return and
any other  matters  relating to Taxes and, in  connection  therewith,  shall (i)
maintain  appropriate  books and records for any and all Taxable  periods or any
portion of a Taxable  period  that may be required  by AT&T's  record  retention
policies;  (ii)  provide to each other such  information  as may be necessary or
useful in the filing of, or any Tax Contest relating to, any such Return;  (iii)
execute and  deliver  such  consents,  elections,  powers of attorney  and other
documents that may be required or appropriate  for the proper filing of any such
Return or in conjunction with any Tax Contest  relating to any such Return;  and
(iv) make available for responding to inquiries of any other party or any Taxing
Authority,  appropriate  employees and officers of and advisors  retained by any
member of the AT&T Services  Group,  the Lucent Group,  or the NCR Group, as the
case may be.

                  5.3.  FILING  OF  RETURNS.   The  Person  that  would  be  the
Controlling Party with respect to any Tax Contest relating to a Return for which
any indemnity  payment,  reimbursement or other payment may be sought under this
Agreement  shall (a) prepare and file,  or cause to be prepared  and filed,  any
such Return within the time  prescribed  for filing such Return  (including  all
extensions of time for filing);  and (b) shall timely pay, or cause to be timely
paid,  the  amount  of any Tax  shown to be due and  owing  on any such  Return;
provided,  however,  that in the case of Taxes which are  Liabilities  of Lucent
pursuant to Section 2.3(a)(ii) of the Separation Agreement, if AT&T or any other
member of the AT&T Group is  required  pursuant to this  Agreement  to file such
Return  and pay the Taxes  shown as due  thereon,  Lucent  will pay to AT&T,  in
advance of the date on which AT&T must pay such  Taxes,  an amount  equal to the
amount of such Taxes which are Liabilities of Lucent. Such Person shall bear all
costs associated with preparing and filing, or causing to be prepared and filed,
any such  Return.  Except as  provided in Section  5.1(c)  hereof  (relating  to
Consolidated Returns), such Person shall establish all Return positions and make
all Tax elections relating to such Returns.

or a corporate division having a "Company Code," "Managed Entity Code" or "Legal
Entity  Code"  set  forth in  Schedule  V, to the  extent  such  information  is
available, and who has not had an intervening period of employment covered by an
interchange  agreement  under which assets and  liabilities  with respect to the
individual  were or are to be  transferred  from an AT&T Pension  Plan, or (iii)
otherwise is identified pursuant to a methodology  approved by the Lucent Senior
Vice President-Human  Resources and the AT&T Senior Vice  President-Benefits and
Compensation,  which  methodology  shall be  consistent  with the  intent of the
parties  that former  employees  of AT&T or a past or present  Affiliate of AT&T
will be aligned  with the entity for which they most  recently  worked and based
upon the business of such entity. Transferred Individuals shall also include the
Lucent Administrative  Employees and the individuals designated as such pursuant
to Section 9.2. An alternate  payee under a QDRO,  alternate  recipient  under a
QMCSO,  beneficiary or covered dependent, in each case, of an employee or former
employee  described in either of the  preceding  two  sentences  shall also be a
Transferred  Individual  with respect to that  employee's  or former  employee's
benefit  under  the  applicable  Plans.  Such  an  alternate  payee,   alternate
recipient, beneficiary, or covered dependent shall not otherwise be considered a
Transferred  Individual  with  respect  to his or her  own  benefits  under  any
applicable  Plans  unless  he or she is a  Transferred  Individual  by virtue of
either of the first two  sentences of this  definition.  In  addition,  AT&T and

individuals,  as  Transferred  Individuals.  An individual  may be a Transferred
Individual pursuant to this definition  regardless of whether such individual is

the Distribution Date, alive, actively employed, on a temporary leave of absence
from active employment, on layoff, terminated from employment, retired or on any
other type of employment or post-employment status relative to an AT&T Plan, and
regardless of whether, as of the Close of the Distribution Date, such individual
is then receiving any benefits from an AT&T Plan. Notwithstanding the foregoing,
if the Distribution does not occur on or before December 31, 1997, references in
this definition to the Close of the  Distribution  Date shall be deemed to refer
to the close of business on the earlier of the date AT&T publicly announces that
the Distribution will not occur and December 31, 1997.

with respect to that  individual's  benefit under the applicable  Plans. Such an

(v)  all  other  Liabilities  relating  to,  arising  out of or  resulting  from
obligations,  liabilities and responsibilities  expressly assumed or retained by
Lucent,  a  Lucent  Entity,  or  a  Lucent  Plan  pursuant  to  this  Agreement.
Notwithstanding  the foregoing,  Lucent shall not, by virtue of any provision of
this Agreement or the Separation and Distribution  Agreement,  be deemed to have
assumed any Excluded Liability or to have agreed to alter or amend any provision
of Article VI of the Separation and Distribution Agreement.

                  (b) EXCLUDED  LIABILITIES.  All  Liabilities to or relating to

Entity not described in the preceding  sentence may, at its request and with the
consent  of  AT&T  (which  shall  not  be  unreasonably   withheld),   become  a

continue through the Close of the Distribution  Date to administer,  or cause to
be  administered,  in accordance  with their terms and applicable  law, the AT&T
Plans,  and shall have the sole  discretion  and authority to interpret the AT&T
Plans as set forth  therein.  Before the Close of the  Distribution  Date,  AT&T
shall not,  without first  consulting  with Lucent (on behalf of itself and each
Lucent Entity which is a Participating  Company),  amend any Material Feature of
any AT&T Plan in which  Lucent or a Lucent  Entity is a  Participating  Company,
except to the extent  such  amendment  would not affect any  benefits  of Lucent
Individuals or Transferred Individuals under such Plan or as may be necessary or
appropriate  to comply with any  collective  bargaining  agreement or applicable
law.

                  (d) LUCENT'S  GENERAL  OBLIGATIONS AS
PARTICIPATING  COMPANY.
Lucent shall perform with respect to its  participation  in the
AT&T Plans,  and
shall cause each other Lucent Entity that is a Participating
Company in any AT&T
Plan to  perform,  the  duties of a  Participating  Company as set forth in such

the   administration   of  claims,   to  the  extent  requested  by  the  claims
administrator of the applicable AT&T Plan; (ii) cooperating fully with AT&T Plan
auditors,   benefit   personnel  and  benefit  vendors;   (iii)  preserving  the

vendors, claims administrators,  trustees or any other entity or individual with
whom AT&T has entered  into an  agreement  relating to the AT&T Plans;  and (iv)
preserving the  confidentiality  of participant  health  information  (including

                  (e) TERMINATION OF PARTICIPATING COMPANY STATUS.  Effective as

to be a  Participating  Company in the AT&T  Plans,  except that Lucent and each
Lucent Entity shall cease to be a Participating  Company in the AT&T Rabbi Trust
as of the Rabbi Trust Determination Date.

         2.3  ESTABLISHMENT  OF LUCENT PLANS.  Effective  Immediately  after the
Distribution  Date,  Lucent  shall  adopt,  or cause to be  adopted,  the Lucent
Pension  Plans,  the Lucent  Savings  Plans,  the Lucent ESOP,  the Lucent Stock
Purchase Plan (if the AT&T Stock Purchase Plan is then in existence), the Lucent
Health and Welfare Plans, and the Lucent Executive Benefit Plans for the benefit
of the Transferred  Individuals and other current,  future, and former employees
of Lucent and the Lucent  Entities.  Except for the Lucent  Long Term  Incentive
Plan and the Lucent Stock Purchase Plan, the foregoing Lucent Plans as in effect
Immediately after the Distribution Date shall be substantially identical in all



<PAGE>

Material Features to the  corresponding  AT&T Plans as in effect as of the Close
of the  Distribution  Date.  The Lucent Long Term  Incentive Plan and the Lucent
Stock  Purchase  Plan shall be adopted  by Lucent and  approved  by AT&T as sole
shareholder of Lucent,  before the Closing Date, to become effective Immediately
after the  Distribution  Date.  Effective as of the Closing  Date,  Lucent shall
adopt, or cause to be adopted,  the Lucent Non-Employee  Director Plans, for the
benefit  of Lucent  Non-Employee  Directors  who were,  immediately  before  the
Closing Date, AT&T  Non-Employee  Directors.  The Lucent  Non-Employee  Director
Plans  shall  be  substantially  identical  in  all  Material  Features  to  the
corresponding AT&T Non-Employee Director Plans as in effect on the Closing Date,
except that they need not provide for the accrual of additional  benefits  after
the Closing Date. In addition, before the Closing Date, Lucent may adopt, and in
that event AT&T shall  approve as sole  shareholder  of Lucent,  a plan or other
arrangement for the payment of compensation of the Lucent Non-Employee Directors
in Lucent Common Stock,  under which the number of shares permitted to be issued
before  the  Close of the  Distribution  Date  shall  not  exceed  10,000 in the
aggregate.

         2.4 TERMS OF PARTICIPATION  BY TRANSFERRED  INDIVIDUALS
IN LUCENT PLANS
AND LUCENT NON-EMPLOYEE DIRECTORS IN LUCENT NON-EMPLOYEE DIRECTOR
PLANS.

                  (a) LUCENT  PLANS.  The Lucent Plans shall be, with respect to
Transferred  Individuals,  in all  respects the  successors  in interest to, and
shall  not  provide   benefits  that   duplicate   benefits   provided  by,  the
corresponding AT&T Plans. AT&T and Lucent shall agree on methods and procedures,
including  amending  the  respective  Plan  documents,  to  prevent  Transferred
Individuals  from  receiving  duplicative  benefits  from the AT&T Plans and the
Lucent  Plans.  Lucent  shall not  permit any Lucent  Plan to  commence  benefit
payments  to any  Transferred  Individual  until it  receives  notice  from AT&T
regarding the date on which  payments  under the  corresponding  AT&T Plan shall
cease. With respect to Transferred  Individuals,  each Lucent Plan shall provide
that  all   service,   all   compensation   and  all   other   benefit-affecting
determinations  that, as of the Close of the Distribution  Date, were recognized
under  the   corresponding   AT&T  Plan  shall,  as  of  Immediately  after  the
Distribution Date,  receive full recognition,  credit, and validity and be taken
into account under such Lucent Plan to the same extent as if such items occurred
under such Lucent Plan,  except to the extent that duplication of benefits would
result. The provisions of this Agreement for the transfer of assets from certain
trusts  relating to AT&T Plans  (including  Foreign Plans) to the  corresponding
trusts  relating to Lucent Plans  (including  Foreign  Plans) are based upon the
understanding  of the  parties  that  each such  Lucent  Plan  will  assume  all
Liabilities  of the  corresponding  AT&T  Plan  to or  relating  to  Transferred
Individuals, as provided for herein. If any such Liabilities are not effectively
assumed by the appropriate Lucent Plan, then the amount of assets transferred to
the  trust  relating  to  such  Lucent  Plan  from  the  trust  relating  to the
corresponding  AT&T Plan shall be recomputed,  ab initio, as set forth below but
taking into account the  retention of such  Liabilities  by such AT&T Plan,  and
assets  shall be  transferred  by the trust  relating to such Lucent Plan to the
trust  relating to such AT&T Plan so as to place each such trust in the position
it would have been in, had the initial  asset  transfer  been made in accordance
with such recomputed amount of assets.

                  (b)   LUCENT   NON-EMPLOYEE   DIRECTOR   PLANS.   The   Lucent
Non-Employee  Director  Plans shall be, with respect to the Lucent  Non-Employee
Directors who  participated  in the  corresponding  AT&T  Non-Employee  Director
Plans,  in all  respects  the  successors  in interest to, and shall not provide
benefits that duplicate benefits provided by such AT&T Plans.

(without
duplication thereof) for Transition Individuals shall be set forth

shall become,  an  Interchange  Company  under the MPA, with all the  applicable
rights and obligations of such an Interchange  Company.  Each Lucent Entity that
is an  Interchange  Company as of the date of this  Agreement  shall continue as
such. Effective as of any date on or after the Participation  Commencement Date,
any other Lucent Entity that becomes a Participating Company in the AT&T Pension
Plans  pursuant  to Section 2.2 may, at its request and with the consent of AT&T
(which  shall not be  unreasonably  withheld),  become an  Interchange  Company.
Effective  Immediately  after the  Distribution  Date,  the Lucent Pension Plans
shall be "Interchange Company Pension Plans" under, and subject to the terms of,
the MPA. AT&T shall use its reasonable  best efforts to seek an amendment of the
MPA to allow Lucent to become a "Tier II Signatory  Company"  under the MPA with
the same rights and obligations as have been granted to AirTouch  International,
Inc.  as a Tier II  Signatory  Company.  Lucent  shall take any and all  action,
including any action reasonably requested by AT&T, to become a Tier II Signatory
Company under the MPA. During the applicable  Transition  Periods,  neither AT&T
nor Lucent shall permit any  Transition  Individual  covered by the  Interchange
Agreements  described above to waive  portability  under the MPA with respect to
movement as a Transition Individual.

                  (b) MANAGEMENT INTERCHANGE AGREEMENT. On or before the Closing
Date,  AT&T and Lucent shall enter into an Interchange  Agreement  providing for
(among  other  things) the  portability  of benefits and mutual  recognition  of
service  during the  Management  Transition  Period with  respect to  Transition
Individuals who terminate  employment with AT&T or an AT&T Entity and who become
Management  Employees (or employees  covered by an alternate benefit program) of
Lucent or a Lucent Entity and Transition  Individuals  who terminate  employment
with Lucent or a Lucent Entity and who become Management Employees (or employees
covered by an  alternate  benefit  program) of AT&T or an AT&T Entity  after the
Distribution Date, as more fully described in Section 2.5(d).

                  (c)  OCCUPATIONAL  INTERCHANGE  AGREEMENT.  On or  before  the
Closing  Date,  AT&T  and  Lucent  shall  enter  into an  Interchange  Agreement
providing  for the  portability  of benefits and mutual  recognition  of service
during the Occupational Transition Period with respect to Transition Individuals
who cease  employment  with AT&T or an AT&T  Entity and who become  Occupational
Employees  of Lucent or a Lucent  Entity and  Transition  Individuals  who cease
employment with Lucent or a Lucent Entity and who become Occupational  Employees
of AT&T or an AT&T Entity after the  Distribution  Date, as more fully described
in Section 2.5(d).

                  (d)  TERMS  OF THE  MANAGEMENT  AND
OCCUPATIONAL  INTERCHANGE
AGREEMENTS.  The Interchange  Agreements described in Sections 2.5(b) and 2.5(c)
shall provide in a mutually  agreeable  manner for the following with respect to
Transition  Individuals:  (i) prohibition of the  commencement of benefits under
any  transferor  AT&T or Lucent  Pension  Plan,  and  suspension of any benefits
already  commenced,  with respect to any  individual  for whom the liability for
benefits is transferred either from the AT&T Pension Plans to the Lucent Pension
Plans or from the Lucent Pension Plans to the AT&T Pension Plans;  (ii) transfer
of  service  credit  between  the  AT&T  Plans  and  the  Lucent  Plans,   where
appropriate;  (iii) transfer of assets and liabilities  between the AT&T Pension
Plans and the Lucent Pension Plans in the same manner and in accordance with the
same methods and  assumptions  as prescribed  by the MPA,  regardless of whether
such employees are covered by the




<PAGE>

MPA (but in no  event  shall a  Transition  Individual  be  entitled  to  obtain
overlapping  benefits under both the MPA and the  Interchange  Agreement);  (iv)
transfer  of  accounts  between the AT&T  Savings  Plans and the Lucent  Savings
Plans;  (v) transfer of accounts between the AT&T ESOP and the Lucent ESOP; (vi)
transfer of accounts  between the AT&T Stock  Purchase Plan and the Lucent Stock

Welfare Plans and the Lucent Health and Welfare Plans of the coverage  elections
and all amounts applied to deductibles and out-of-pocket  maximums met under the
other  company's  Health  and  Welfare  Plans for plan  years in the  applicable
Transition Period;  (viii) mutual maintenance and recognition by the AT&T Health
and  Welfare  Plans and the Lucent  Health  and  Welfare  Plans of all  lifetime
maximum  benefits  reached under the other  company's  Health and Welfare Plans;
(ix)  transfer  of service  credit,  assets,  and  liabilities  between the AT&T
Executive  Benefit Plans and the Lucent Executive  Benefit Plans and the related
trusts,  insurance  policies and other  funding  vehicles;  (x)  allocation  and
transfer of RFA assets and  liabilities  between the applicable  AT&T Health and
Welfare Plans and the applicable Lucent Health and Welfare Plans and the related
trusts,  insurance  policies and other funding vehicles;  and (xi) assumption of
Individual Agreements.  Each of the service crediting provisions described above
shall be subject to any  applicable  "service  bridging"  or "break in  service"
rules under the AT&T Plans and the Lucent Plans.

                  (e)  RESTRICTION  ON PLAN  AMENDMENTS.  During the  Management
Transition Period,  neither AT&T nor Lucent shall adopt any amendment,  or allow
any amendment to be adopted,  to any of their respective Pension Plans,  Savings
Plans or ESOPs that would violate Code Section 411(d)(6) or that would create an
optional form of benefit subject to Code Section 411(d)(6).

identical  in all  Material  Features  to the trust  established  under the AT&T

of Lucent or its authorized  delegate after the Close of the  Distribution  Date
(and Lucent shall seek such  ratification  within 60 days after the Close of the

the difference (positive or negative) between (x) the amount of assets as of the
Close of the  Distribution  Date of the AT&T MPP and (y) the sum of the  Funding
Policy Amounts for the AT&T MPP and the  corresponding  Lucent Pension Plan. The
assumptions used in determining the 414(l)(1) Amount for each Pension Plan shall
be those used in the  determination of the minimum required  contribution  under
ERISA for the Plan year  beginning  January 1, 1996,  except  that the  discount
rates shall be the rates issued by the PBGC for valuing annuities in terminating
single-employer  pension  plans  during  the month  containing  the Close of the
Distribution Date.

                           (B) If the aggregate amount of the
assets of the AT&T
MPP as of the  Close of the  Distribution  Date is not less  than the sum of the
414(l)(1)  Amounts for the AT&T MPP and the  corresponding  Lucent Pension Plan,
then such assets shall be allocated  between the AT&T MPP and the  corresponding
Lucent  Pension  Plan in  accordance  with  the  following:  (1) if the  Initial
Allocation  Amount is greater than or equal to the 414(l)(1) Amount for the AT&T
MPP, and the Initial Allocation Amount is greater than or equal to the 414(l)(1)
Amount for the  corresponding  Lucent  Pension Plan,  then the amounts of assets
allocated to the AT&T MPP and the corresponding  Lucent Pension Plan shall equal
their  respective  Initial  Allocation  Amounts;  (2) if the Initial  Allocation
Amount is greater  than or equal to the  414(l)(1)  Amount for the AT&T MPP, but
the  Initial  Allocation  Amount  is less  than  the  414(l)(1)  Amount  for the
corresponding  Lucent Pension Plan,  then the amount of assets  allocated to the
Lucent Pension Plan shall equal the 414(l)(1)  Amount for that Pension Plan, and
the amount of assets allocated to the AT&T MPP shall equal the excess of (x) the
total amount of assets,  as of the Close of the  Distribution  Date, of the AT&T
MPP over (y) the 414(l)(1) Amount for the corresponding Lucent Pension Plan; and
(3) if the Initial  Allocation  Amount is less than the 414(l)(1) Amount for the
AT&T MPP,  but the  Initial  Allocation  Amount is greater  than or equal to the
414(l)(1) Amount for the  corresponding  Lucent Pension Plan, then the amount of
assets  allocated to the AT&T MPP shall equal the 414(l)(1)  Amount for the AT&T
MPP, and the amount of assets allocated to the corresponding Lucent Pension Plan
shall equal the excess of (x) the total amount of assets, as of the Close of the
Distribution  Date, of the AT&T MPP over (y) the  414(l)(1)  Amount for the AT&T
MPP.

                           (C) If the aggregate amount of the
assets of the AT&T
MPP as of the  Close  of the  Distribution  Date  is  less  than  the sum of the
414(l)(1)  Amounts for the AT&T MPP and the  corresponding  Lucent Pension Plan,
then such assets shall be allocated  between the AT&T MPP and the  corresponding
Lucent Pension Plan as follows: (i) AT&T






<PAGE>

and Lucent shall obtain a quote from a mutually agreeable  insurance company for
the provision of immediate and deferred annuities payable under the AT&T MPP and
the  corresponding  Lucent Pension Plan for all accrued  benefits under the AT&T
MPP as of the Close of the Distribution Date; (ii) if the amount of assets as of
the Close of the  Distribution  Date is not less than the amount of such  quote,
the  amount of assets  allocated  to the AT&T MPP and the  corresponding  Lucent
Pension  Plan shall equal the portion of the quote  allocable  to each plan plus
one-half of the  excess,  if any,  over such  quote;  and (iii) if the amount of
assets as of the Close of the Distribution  Date is less than the amount of such
quote,  the  amount of assets  allocated  to the AT&T MPP and the  corresponding
Lucent  Pension  Plan  shall  be  determined  on a  plan  termination  basis  in
accordance  with ERISA Section 4044 using the same  assumptions as those used in
computing the 414(l)(1) Amounts.

                  (ii) CALCULATION OF THE AT&T PP'S ASSET
ALLOCATION.  The asset
allocation  of the AT&T PP and the  corresponding  Lucent  Pension
Plan shall be
determined by applying Section  3.2(b)(i) but  substituting  "AT&T
PP" for "AT&T
MPP" wherever it appears in that section.

                  (iii)  SEGREGATION OF LUCENT PENSION PLANS'  INTERESTS  WITHIN
THE AT&T GROUP PENSION  TRUST.  The actual  segregation  of the interests of the
Lucent  Pension  Plans in the AT&T  Group  Pension  Trust  into  separate  trust
accounts  shall  occur as soon as  practicable  after  the  calculation  of such
interests  pursuant to Section  3.2(b)(i) and (ii),  but in no event before AT&T
determines that the calculation and the data on which it is based are acceptably
complete,  accurate and  consistent.  In addition,  the  interests so calculated
shall be adjusted as of the date of the actual segregation by AT&T to the extent
necessary or  appropriate  to reasonably and  appropriately  reflect  additional
pension  contributions,  interest,  investment  gains and  losses,  and  benefit
payments and data corrections,  enhancements, and computational refinements from
Immediately  after  the  Distribution  Date  through  the  date  of  the  actual
segregation of such interests. If the master pension trust established by Lucent
pursuant  to the last  sentence  of  Section  3.1 is for any  reason  not then a
participating  trust in the AT&T Group Pension Trust,  such master pension trust
shall be entitled to receive its allocable share of the assets of the AT&T Group
Pension Trust as determined pursuant to the foregoing provisions of this Section
3.2(b) in  redemption of the  interests  therein of the Lucent  Pension Plans as
promptly  as  prudently  practicable.  Such  allocable  share  shall  consist of
Lucent's  allocable  share of each  class of  assets in the AT&T  Group  Pension
Trust, unless AT&T and Lucent agree otherwise.

Distribution Date, Lucent shall establish, or cause to be established,  separate
trusts  qualified  under Code Section  401(a),  exempt from taxation  under Code
Section 501(a)(1), and forming part of the Lucent LTSPME and Lucent RSPSP, which
shall be participating trusts in the AT&T Management Savings Group Trust.

         (b) ASSUMPTION OF LIABILITIES AND TRANSFER OF ASSETS.
Effective
Immediately after the Distribution Date: (i) the Lucent LTSPME and

<PAGE>

the accounts of the Transferred  Individuals  under the AT&T LTSPME and the AT&T
RSPSP which are held by their related trusts as of the Close of the Distribution
Date to be transferred to the Lucent LTSPME and the Lucent RSPSP,  respectively,
and their related trusts, and Lucent shall cause such transferred accounts to be
accepted by such plans and trusts. Effective no later than Immediately after the
Distribution  Date,  Lucent shall use its reasonable  best efforts to enter into
such  agreements  satisfactory  to Lucent to  accomplish  such  assumptions  and
transfers, the maintenance of the necessary participant records, the appointment
of Fidelity  Institutional  Trust  Company as initial  trustee  under the Lucent
LTSPME and the Lucent RSPSP, and the engagement of Fidelity  Records  Management
Company as initial recordkeeper under such plans.

         4.2 LTSSPS AND LESOPS.

                  (a) OCCUPATIONAL  SAVINGS PLAN TRUSTS.  Effective  Immediately
after the Distribution Date, Lucent shall establish, or cause to be established,
a separate trust,  qualified in accordance with Code Section 401(a), exempt from
taxation  under Code Section  501(a)(1),  and forming part of the Lucent  LTSSP,
which shall be a  participating  trust in the AT&T  Occupational  Savings  Group
Trust.

                  (b)  ASSUMPTION OF LTSSP  LIABILITIES.  Effective  Immediately
after the  Distribution  Date:  (i) the Lucent  LTSSP shall assume and be solely
responsible for all Liabilities to or relating to Transferred  Individuals under
the AT&T LTSSP,  other than Liabilities  referred to in Section 4.2(c); and (ii)
AT&T shall cause the  accounts  of the  Transferred  Individuals  under the AT&T
LTSSP  which are held by its related  trust as of the Close of the  Distribution
Date to be  transferred  to the Lucent LTSSP and its related  trust,  and Lucent
shall cause such  transferred  accounts to be accepted by such plans and trusts.
Effective no later than Immediately  after the Distribution  Date,  Lucent shall
use its reasonable best efforts to enter into agreements  satisfactory to Lucent
to accomplish  such  assumption and transfer,  the  maintenance of the necessary
participant  records, the appointment of the then-current trustee under the AT&T
LTSSP as initial  trustee  under the Lucent  LTSSP,  and the  engagement  of the
then-current  recordkeeper of the AT&T LTSSP as initial  recordkeeper under such
plans.

                  (c) LEVERAGED STOCK OWNERSHIP PLAN.

                           (i) Effective Immediately after the
Distribution
Date, Lucent shall establish, or cause to be established,  a separate trust (the
"Lucent LESOP Trust"),  qualified in accordance with Code Section 401(a), exempt
from taxation under Code Section 501(a), and forming part of the Lucent LTSSP.

                           (ii) Before the Distribution Date, AT&T
and Lucent
shall use their  reasonable  best  efforts  to  renegotiate  the note  agreement
between Bankers Trust Company, as trustee of the AT&T LESOP, and various lenders
dated March 9, 1990 (the "Existing Acquisition Loan") so that it is restructured
into two note  agreements  for two  loans,  the  principal  amount  of one being
attributable  to the  accounts  to be  transferred  to the  Lucent  LESOP  Trust
pursuant  to  Section  4.2(c)(iii)  (the  "Lucent  Acquisition  Loan")  and  the
principal  amount of the other being  attributable to the accounts  remaining in
the AT&T LESOP (the "AT&T Acquisition Loan"). The principal amount of the Lucent
Acquisition  Loan shall be determined by multiplying the principal amount of the
Existing  Acquisition Loan as of the Distribution Date by the fraction described
in Section 4.2(c)(iii).  AT&T and Lucent shall use their reasonable best efforts
to cause the terms of the AT&T Acquisition Loan and the Lucent  Acquisition Loan
to be as favorable to Lucent and AT&T, respectively, as the




<PAGE>

terms  of the  Existing  Acquisition  Loan,  and,  to the  extent  permitted  by
applicable law,  including Code Section 133, the terms of the Lucent Acquisition
Loan to be no less favorable to Lucent and the Lucent LESOP Trust than the terms
of the AT&T Acquisition Loan are to AT&T and the AT&T LESOP Trust.

                           (iii) Effective Immediately after the
Distribution
Date:  (A) the  Lucent  LTSSP  shall  assume and be solely  responsible  for all
Liabilities to or relating to Transferred  Individuals under the AT&T LTSSP that
relate to, arise out of or result from the AT&T LESOP;  (B) AT&T shall cause the
accounts of the Transferred  Individuals  under the AT&T LTSSP which are held by
the AT&T LESOP Trust as of the Close of the Distribution  Date to be transferred
to the Lucent LTSSP and the Lucent LESOP Trust; (C) if the Existing  Acquisition
Loan  has  been  restructured  into,  and  subject  to the  terms  of,  the AT&T
Acquisition Loan and the Lucent  Acquisition  Loan, AT&T shall cause the trustee
of the AT&T LESOP Trust to  transfer to the Lucent  LESOP Trust a portion of the
assets  held in the  "Suspense  Account"  (as  defined in Article 20 of the AT&T
LTSSP)  attributable to the Transferred  Individuals,  determined by multiplying
the number of shares of AT&T Common Stock and the fair market value of any other
assets held in such suspense account as of the Close of the Distribution Date by
a fraction,  the numerator of which is the amount deemed to be employer matching
contributions  attributable to Lucent  Individuals and other employees of Lucent
and the Lucent Entities for the latest calendar month that ends on or before the
Distribution Date, and the denominator of which is the total amount deemed to be
employer matching  contributions for all participants in the AT&T LTSSP for such
calendar month; and (D) Lucent shall cause all accounts  transferred pursuant to
clauses (B) and (C) to be accepted  by such plan and trust.  Effective  no later
than Immediately  after the Distribution  Date,  Lucent shall use its reasonable
best efforts to enter into  agreements  acceptable to Lucent to accomplish  such
assumption  and transfers,  the  maintenance  of the necessary  participant  and
suspense  account  records,  the appointment of Bankers Trust Company as initial
trustee  of the Lucent  LESOP  Trust,  and the  engagement  of the  then-current
recordkeeper of the AT&T LESOP as initial recordkeeper of the Lucent LESOP.

                           (iv) The parties intend that, as the
result of the
above-described transactions,  after the Close of the Distribution Date, each of
them will be the sponsor of an  "employee  stock  ownership  plan" as defined in
Code  Section  4975(e)(7),  and  that  the  AT&T  Acquisition  Loan  and  Lucent
Acquisition  Loan will be exempt from the  prohibited  transaction  rules of the
Code and ERISA pursuant to Code Section 4975(d)(3).

                           (v) The parties acknowledge that, as a
result of the
transfer of assets described in Section  4.2(c)(iii) and the Distribution,  both
the AT&T LESOP and the Lucent  LESOP will,  after the Close of the  Distribution
Date, hold shares of both AT&T Common Stock and Lucent Common Stock. The parties
further  acknowledge  that  applicable  law generally  prohibits such plans from
holding  securities that are not  "qualifying  employer  securities"  within the
meaning  of  Code  Section  409  for  more  than a  reasonable  time  after  the
Distribution Date unless the IRS grants an extension of time.
Accordingly,  AT&T
and Lucent  shall each  request the IRS to grant an  extension  of such  holding
period as their financial advisors shall deem prudent to allow the AT&T LESOP to
dispose of the shares of Lucent  Common Stock  received by it as a result of the
Distribution  and to allow the  Lucent  LESOP to  dispose  of the shares of AT&T
Common  Stock it holds as a result  of the  transfer  of  accounts  pursuant  to
Section  4.2(c)(iii),  and, in each case,  to reinvest  in  qualifying  employer
securities,  in a  manner  consistent  with  the  best  interests  of the  LESOP
participants.  In furtherance of such dispositions and  reinvestments,  AT&T and
Lucent shall take all actions necessary or appropriate to permit the exchange of
shares of Lucent  Common  Stock held by the AT&T LESOP  Trust for shares of AT&T
Common Stock held by the Lucent




<PAGE>

LESOP Trust,  including the engagement of a fiduciary not affiliated with either
AT&T or Lucent to advise the parties  regarding  the time and manner  (including
the  exchange  ratio) of such  exchange.  If the  restructuring  of the Existing
Acquisition  Loan results in any prepayment or "make whole"  penalty,  or if the
interest  rate  payable  pursuant  to the Lucent  Acquisition  Loan  exceeds the
interest rate payable pursuant to the AT&T Acquisition Loan or vice versa,  then
Lucent  and  AT&T  and  their  respective  LESOPs  shall  bear  the cost of such
penalties  and the excess  interest  expense so  incurred in  proportion  to the
relative initial principal  amounts of the Lucent  Acquisition Loan and the AT&T
Acquisition  Loan,  taking  into  account  any  tax  benefits  realized  or  tax
detriments suffered in connection therewith.

                           (vi) Notwithstanding the foregoing, if
it is
determined by AT&T or Lucent before the Distribution Date that the restructuring
of the Existing  Acquisition Loan is not practicable on commercially  reasonable
terms and conditions,  then, unless AT&T and Lucent agree otherwise,  AT&T shall
terminate the AT&T LESOP and its related trust before the Distribution Date, and
shall  direct the trustee of the AT&T LESOP trust to sell  sufficient  shares of
AT&T  Common  Stock  held  under  the AT&T  LESOP  trust to repay  the  Existing
Acquisition Loan. Any remaining "Financed Shares" (as defined in the AT&T LESOP)
that  are  released  after  repayment  of the loan  and not the  subject  of any
subsequent  refinancing  shall be used by the  Participating  Companies  to make
matching  contributions  with  respect  to  periods  before  the  Close  of  the
Distribution  Date to the AT&T LTSSP in accordance with their  obligations under
the AT&T LTSSP.

         4.3  ESOPS.

                  (a) ESOP TRUST.  Effective  Immediately after the Distribution
Date, Lucent shall establish, or cause to be established,  a separate trust (the
"Lucent ESOP Trust"),  qualified in accordance with Code Section 401(a),  exempt
from taxation under Code Section 501(a), and forming part of the Lucent ESOP.

                  (b)  ASSUMPTION OF LIABILITIES AND TRANSFER OF
ASSETS.

                           (i) Effective Immediately after the
Distribution
Date, the Lucent ESOP shall assume and be solely responsible for all Liabilities
to or relating to  Transferred  Individuals  under the AT&T ESOP, and AT&T shall
cause the accounts of the Transferred  Individuals under the AT&T ESOP as of the
Close of the  Distribution  Date to be  transferred  to the Lucent  ESOP and the
Lucent  ESOP  Trust,  and Lucent  shall cause such plan and trust to accept such
assets.  Effective no later than Immediately after the Distribution Date, Lucent
shall use its  reasonable  best efforts to enter into  agreements  acceptable to
Lucent to accomplish  such  assumptions  and transfers,  the  maintenance of the
necessary  participant  records,  the  appointment  of Midlantic Bank as initial
trustee of the Lucent ESOP Trust and the  engagement of American  Transtech Inc.
as initial recordkeeper of the Lucent ESOP.

                           (ii) The parties acknowledge that, as a
result of the
transfer of assets described in Section 4.3(b)(i) and the Distribution, both the
AT&T ESOP and the Lucent ESOP will, after the Distribution  Date, hold shares of
both AT&T Common Stock and Lucent Common Stock and that, in order to continue to
qualify as employee stock  ownership  plans,  each such plan will be required to
dispose of securities that are not qualifying  employer  securities and reinvest
in  qualifying  employer  securities.   The  parties  further  acknowledge  that
applicable law generally  prohibits such plans from holding  securities that are
not "qualifying  employer securities" within the meaning of Code Section 409 for
more than a reasonable time after the Distribution Date unless the IRS grants an
extension  of time.  Accordingly,  AT&T and Lucent shall each request the IRS to
grant an extension of such




<PAGE>

holding period as their financial  advisors shall deem prudent to allow the AT&T
ESOP to dispose of the shares of Lucent Common Stock  received by it as a result
of the  Distribution  and to allow the  Lucent  ESOP to dispose of the shares of
AT&T Common Stock it holds as a result of the  transfer of accounts  pursuant to
Section  4.3(b)(i),  and,  in each case,  to  reinvest  in  qualifying  employer
securities,  in a  manner  consistent  with  the  best  interests  of  the  ESOP
participants.  In furtherance of such dispositions and  reinvestments,  AT&T and
Lucent shall take all actions necessary or appropriate to permit the exchange of
shares of Lucent  Common  Stock  held by the AT&T ESOP  Trust for shares of AT&T
Common  Stock held by the Lucent  ESOP  Trust,  including  the  engagement  of a
fiduciary  not  affiliated  with  either  AT&T or Lucent to advise  the  parties
regarding the time and manner (including the exchange ratio) of such exchange.

                            HEALTH AND WELFARE PLANS

         5.1  ESTABLISHMENT  OF MIRROR  HEALTH AND WELFARE  PLAN  TRUSTS.  On or
before  the  Distribution   Date,  Lucent  shall  establish,   or  cause  to  be
established:  (a) the Lucent  Health  Plans  Benefit  Trust,  for the purpose of
funding claims, other than for post-retirement benefits, under the Lucent Health
Plans;  (b) the Lucent  Management  VEBA,  for the purpose of funding claims for
post-retirement  benefits of employees not covered by any collective  bargaining
agreement  under the Lucent  Health  Plans;  (c) the Lucent Union VEBA,  for the
purpose of funding claims for  post-retirement  benefits under the Lucent Health
Plans of employees  covered by a collective  bargaining  agreement;  and (d) the
Lucent LTD VEBA, for the purpose of funding long-term  disability and disability
pension  benefits under the Lucent Health and Welfare  Plans.  Such trusts shall
meet the requirements of Code Sections 419, 419A, 501(a), and 501(c)(9).  Lucent
shall use its reasonable best efforts to enter into  agreements  satisfactory to
Lucent  for the  appointment  as  initial  trustee  under each such trust of the
trustee of the corresponding AT&T trust.

         5.2 ASSUMPTION OF HEALTH AND WELFARE PLAN LIABILITIES.

                  (a) Immediately  after the Distribution  Date, all Liabilities
to or  relating  to  Transferred  Individuals  under the AT&T Health and Welfare
Plans shall  cease to be  Liabilities  of the AT&T Health and Welfare  Plans and
shall be assumed by the corresponding Lucent Health and Welfare Plans.

                  (b) Notwithstanding  Section 5.2(a), all treatments which have
been  pre-certified for or are being provided to a Transferred  Individual as of
the Close of the Distribution Date shall be provided without  interruption under
the  appropriate  AT&T Health and Welfare Plan until such treatment is concluded
or discontinued  pursuant to applicable plan rules and  limitations,  but Lucent
shall continue to be responsible for all Liabilities relating to, arising out of
or resulting from such on-going  treatments as of the Close of the  Distribution
Date.

                  (c)  Lucent  shall  assume,  effective  Immediately  after the
Distribution Date, all Liabilities relating to, arising out of or resulting from
special  commitments made by AT&T before the Close of the  Distribution  Date to
provide  benefits to or with respect to  Transferred  Individuals  for custodial
care or other  services  not covered by any AT&T  Health and Welfare  Plans (but
only if such special commitments were made with the prior written consent of the
Lucent Senior Vice President, Human Resources or his delegate, to

                                  April 1, 1996



                            Lucent Technologies Inc.
                              600 Mountain Avenue
                            Murray Hill, N.J. 07974

Dear Sirs:

         With  reference  to  the  registration   statement  on  Form  S-1  (No.
333-00703; the "Registration  Statement") filed by Lucent Technologies Inc. (the
"Company") with the Securities and Exchange  Commission under the Securities Act
of 1933, as amended,  relating to  127,650,000  shares of the  Company's  common
stock,  par value $0.01 per share (the  "Common  Stock"),  we are of the opinion
that:

         1.      the Company is a duly organized and validly
existing
                 corporation under the laws of the State of
Delaware;

         2.      the issuance of the Common Stock has been duly
authorized by
                 appropriate corporate action; and

         3.      when the Common Stock has been issued,  paid for
and  delivered
                 pursuant to a sale in the manner  described in
the Registration
                 Statement, such Common Stock will be validly
issued, fully paid
                 and non-assessable.

          We hereby  consent to the filing of this opinion  with the  Securities
and  Exchange  Commission  in  connection  with the  filing of the  Registration
Statement.  We also consent to the making of the statement with respect to us in
the related prospectus under the heading "Legal Opinions".

                                              Very truly yours,

                                             /s/ Wachtell, Lipton,

the extent such commitments are made after the Participation Commencement Date).
Before the Close of the Distribution  Date, AT&T shall transfer to Lucent copies
of all documentation,  and a complete written  description,  of the terms of all
such special commitments to Transferred Individuals.

         5.3 VEBA ASSET TRANSFERS. This Section 5.3 shall govern the transfer of
assets from the AT&T Health  Trusts  (other than the AT&T Health  Plans  Benefit
Trust) to the  corresponding  Lucent Health Trusts and from the AT&T LTD VEBA to
the Lucent LTD VEBA,  except to the extent that  Section 5.5 is  applicable.  As
soon as  practicable  after  the  Close of the  Distribution  Date,  AT&T  shall
determine the aggregate present value, as of the Close of the Distribution Date,
of the future  benefit  obligations  of each AT&T Plan  funded by a VEBA  ("VEBA
Plans"),  with respect to  Transferred  Individuals  who are eligible to receive
benefits under the applicable VEBA Plan as of the Close of the Distribution Date
(and, in the case of any  post-retirement  health benefits,  who have terminated
employment as of the Close of the  Distribution  Date).  As soon as  practicable
after such determination is made, there shall be transferred from each AT&T VEBA
to the corresponding  Lucent VEBA an amount of assets having a fair market value
on the  date of  transfer  equal  to the  amount  determined  by  dividing  such
aggregate  present value of future benefit  obligations  for the applicable VEBA
Plans  of  Lucent  by the  aggregate  of all  such  present  values  of all  the
applicable  VEBA  Plans of AT&T and all the  applicable  VEBA  Plans of  Lucent,
multiplied  by the fair market  value of the assets of the AT&T VEBA on the date
of  transfer,  adjusted  to take into  account  the extent to which AT&T  and/or
Lucent has opted to forego reimbursement from the applicable VEBA of any benefit
obligation  that was paid by AT&T or  Lucent,  as  applicable,  on or after  the
Participation Commencement Date and before the Close of the Distribution Date.

         5.4 TRANSFER OF RETIREMENT  FUNDING  ACCOUNT  ASSETS.  This Section 5.4
shall  apply to AT&T  Health and  Welfare  Plans with group term life  insurance
policies  that have RFAs  maintained  for the purpose of  accumulating,  through
employer contributions in advance of employee retirements,  a fund to be used to
pay all or a portion of the costs for continuing  life insurance  protection for
employees after their retirement.  As soon as practicable after the Close of the
Distribution Date, there shall be transferred to the corresponding RFA of Lucent
an amount of assets  (determined  by AT&T subject to audit by Coopers & Lybrand)
having a fair market value as of the Close of the Distribution Date equal to the
product of (a) the present value, as of the Close of the  Distribution  Date, of
the future  benefit  obligation  with respect to  Transferred  Individuals to be
discharged  from the RFA,  divided by the  present  value of the future  benefit
obligations with respect to all individuals  whose benefits are to be discharged
from the RFA assets as of the Close of the Distribution  Date times (b) the fair
market value of all RFA assets as of the Close of the  Distribution  Date.  AT&T
and Lucent shall  adopt,  and shall use their  reasonable  best efforts to cause
their  insurers to adopt,  procedures  to  implement  such asset  transfers in a
reasonable and expeditious  manner that is consistent with the underlying  group
life insurance  contracts and  applicable  legal  requirements.  Nothing in this
Agreement  shall be interpreted  to provide that any assets so transferred  have
reverted to AT&T or Lucent.

         5.5 VEBAs  FUNDED WITH  TRUST-OWNED  LIFE  INSURANCE.  This Section 5.5
shall govern  transfers of assets of AT&T VEBAs that are funded,  in whole or in
part, with trust-owned life insurance policies.

                  (a) GENERAL PROVISIONS. As soon as practicable
after the Close
of the Distribution Date, AT&T shall cause each such AT&T VEBA to
transfer to
the corresponding Lucent VEBA such assets as are attributable to
Transferred
Individuals who are eligible to




<PAGE>

receive post-retirement health benefits under the AT&T Health Plans with respect
to such AT&T  VEBA;  provided,  that AT&T  shall not be  required  to cause such
transfer to occur before AT&T has obtained  appropriate  rulings from regulatory
agencies   indicating   that  the  transfers  do  not  contravene  any  statute,
regulation, or technical pronouncement.

                  (b) AT&T MANAGEMENT VEBA:  TRUST-OWNED LIFE INSURANCE  (VEBA).
To accomplish the transfers  required by Section 5.5(a), all or a portion of the
Trust-Owned  Life Insurance  (VEBA) policies and any residual assets in the AT&T
Management  VEBA shall be allocated  between the trustee of the AT&T  Management
VEBA,  and the trustee of the Lucent  Management  VEBA, in  accordance  with the
following procedures.

                           (i) AT&T shall determine the extent to
which the
assets of the AT&T  Management VEBA are sufficient to satisfy all Liabilities to
or relating to Transferred  Individuals who have  terminated  employment and are
eligible to receive  post-retirement health benefits under the AT&T Health Plans
with  respect to the AT&T  Management  VEBA as of the Close of the  Distribution
Date.

                           (ii) AT&T shall instruct the trustee of
the AT&T
Management  VEBA  to  transfer  one of the  Trust-Owned  Life  Insurance  (VEBA)
policies to the Lucent  Management VEBA. AT&T shall determine which policy shall
be transferred  based on the present values of relative  post-retirement  health
liabilities  (benefit  obligations)  retained  by AT&T  and  assumed  by  Lucent
pursuant to this  Agreement,  without regard to which entity employs the insured
individuals,  provided,  that  before such  transfer,  AT&T shall  instruct  the
trustee of the AT&T  Management  VEBA to adjust and/or  allocate the cash values
under the Trust-Owned  Life Insurance (VEBA) policies such that the policy to be
transferred to the Lucent Management VEBA shall have a proportionate  cash value
consistent with the proportion of post-retirement  health  liabilities  (benefit
obligations) to be assumed by Lucent.  Upon such assignment,  the trustee of the
Lucent  Management  VEBA  shall  assume  and  be  solely   responsible  for  all
Liabilities relating to, arising out of or resulting from such policy, including
the  payment of any  premiums  and any loan  repayments  required,  and shall be
entitled to all benefits, under the policy.

                  (c)  OTHER  ASSET  TRANSFERS.   To  accomplish
the  transfers
required by Section 5.5(a),  a portion of the assets of the AT&T
Management VEBA
(other than  Trust-Owned Life Insurance (VEBA) policies) shall be transferred to
the Lucent  Management VEBA to the extent  necessary so that  immediately  after
such  transfer and the  transfer  pursuant to Section  5.5(b),  the ratio of the
assets of each such VEBA trust to the liabilities payable therefrom as described
in Section 5.5(b)(i), is equal.

                  (d)   ADMINISTRATION.   Lucent  and  AT&T   shall   share  all
information  necessary to determine when and whether any individuals  insured by
the Trust-Owned Life Insurance (VEBA) policies owned by the trustees of the AT&T
Management VEBA and Lucent Management VEBA,  respectively,  are deceased, and as
otherwise necessary to administer their respective Management VEBAs.

         5.6  CONTRIBUTIONS  TO,  INVESTMENTS OF AND  DISTRIBUTIONS  FROM VEBAS.
Before the Close of the  Distribution  Date,  AT&T shall have sole  authority to
direct the trustee of the AT&T Health  Trusts and AT&T LTD VEBA as to the timing
and manner of any contributions to the AT&T Health Trusts and AT&T LTD VEBA, the
investment of any trust assets, and the distributions  and/or transfers of trust
assets to AT&T,  Lucent,  any  Participating  Company in the trusts,  any paying
agent, any successor trustee, or any other Person.

         5.7 VENDOR CONTRACTS.

                         (a) THIRD-PARTY ASO CONTRACTS.

                           (i) AT&T shall use its reasonable best
efforts to
amend  each   administrative   services   only   contract   with  a  third-party
administrator  that relates to any of the AT&T Health and Welfare Plans (an "ASO
Contract")  in  existence as of the date of this  Agreement to permit  Lucent to
participate  in the terms and  conditions of such ASO Contract from  Immediately
after the Distribution Date until the expiration of the financial fee guarantees
in effect under such ASO Contract as of the Close of the Distribution Date. AT&T
shall use its reasonable best efforts to cause all ASO Contracts into which AT&T
enters after the date of this Agreement but before the Close of the Distribution
Date  (including  contracts with a subrogation  vendor,  a COBRA  administration
vendor and a Disability 2000 vendor) to allow Lucent to participate in the terms
and conditions thereof effective  Immediately after the Distribution Date on the
same basis as AT&T.

                           (ii) AT&T shall have the right to
determine, and
shall promptly notify Lucent of, the manner in which Lucent's  participation  in
the  terms  and  conditions  of  ASO  Contracts  as set  forth  above  shall  be
effectuated.  The  permissible  ways  in  which  Lucent's  participation  may be
effectuated include  automatically making Lucent a party to the ASO Contracts or
obligating  the third party to enter into a separate  ASO  Contract  with Lucent
providing  for  the  same  terms  and  conditions  as are  contained  in the ASO
Contracts to which AT&T is a party.  Such terms and conditions shall include the
financial  and  termination  provisions,   performance  standards,  methodology,
auditing policies,  quality measures,  reporting requirements and target claims.
Lucent hereby authorizes AT&T to act on its behalf to extend to Lucent the terms
and conditions of the ASO Contracts.  Lucent shall fully  cooperate with AT&T in
such efforts,  and Lucent shall not perform any act,  including  discussing  any
alternative  arrangements  with any third  party,  that would  prejudice  AT&T's
efforts.

                           (iii) If AT&T determines that it will
not be
successful in negotiating  contract  language that will permit  compliance  with
Sections 5.7(a)(i) and 5.7(a)(ii),  AT&T shall so notify Lucent promptly, but in
no event later than July 20,1996,  and after such notification,  Lucent shall be
released  from  the  restriction  contained  in the  last  sentence  of  Section
5.7(a)(ii).  In  such  case,  AT&T  shall  offer  a  contingency  plan  for  the
administration of the portion of the Lucent Health and Welfare Plans affected by
the unavailability of such ASO Contract, including, if possible, an offer by the
third-party  administrator under the relevant ASO Contract of its services under
a  separate  contract  with  Lucent,  with  terms and  conditions  as similar as
practicable  to those of the ASO Contract  with AT&T.  Lucent  shall,  effective
Immediately  after the Distribution  Date, either adopt its own contingency plan
or the contingency plan established by AT&T for such arrangement.

                          (b) GROUP INSURANCE POLICIES.

                           (i) This Section 5.7(b) applies to
group insurance
policies  not  subject to  allocation  or  transfer  pursuant  to the  foregoing
provisions of this Article V ("Group Insurance Policies").

                           (ii) AT&T shall use its reasonable best
efforts to
amend each Group Insurance  Policy in existence as of the date of this Agreement
for the  provision  or  administration  of  benefits  under the AT&T  Health and
Welfare Plans to permit Lucent to





<PAGE>

participate  in the terms and conditions of such policy from  Immediately  after
the  Distribution  Date  until  the  expiration  of the  financial  fee and rate
guarantees  in effect under such Group  Insurance  Policy as of the Close of the
Distribution Date. AT&T shall use its reasonable best efforts to cause all Group
Insurance Policies into which AT&T enters or which AT&T renews after the date of
this Agreement but before the Close of the Distribution  Date to allow Lucent to
participate in the terms and conditions thereof effective  Immediately after the
Distribution Date on the same basis as AT&T.

                           (iii) Lucent's participation in the
terms and
conditions  of  each  such  Group  Insurance  Policy  shall  be  effectuated  by
obligating the insurance  company that issued such  insurance  policy to AT&T to
issue one or more separate  policies to Lucent.  Such terms and conditions shall
include the  financial and  termination  provisions,  performance  standards and
target claims.  Lucent hereby  authorizes AT&T to act on its behalf to extend to
Lucent the terms and conditions of such Group Insurance  Policies.  Lucent shall
fully cooperate with AT&T in such efforts, and Lucent shall not perform any act,
including discussing any alternative arrangements with third parties, that would
prejudice AT&T's efforts.

                           (iv) If AT&T determines that it will
not be
successful in negotiating  policy  provisions  that will permit  compliance with
Sections 5.7(b)(ii) and 5.7(b)(iii),  AT&T shall so notify Lucent promptly,  but
in no event later than July 20, 1996, and after such notification,  Lucent shall
be  released  from the  restriction  contained  in the last  sentence of Section
5.7(b)(iii).  In such case, AT&T shall use its reasonable best efforts to either
continue  to cover  Lucent  under  its Group  Insurance  Policies  or  procure a
separate  policy for Lucent until Lucent has procured  such  separate  insurance
policy or made other  arrangements  for replacement  coverage,  and Lucent shall
bear all costs incurred by AT&T to continue such coverage.

                  (c)  HMO AGREEMENTS.

                           (i) Before the Distribution Date, AT&T
shall use its
reasonable  best efforts to amend all letter  agreements  with HMOs that provide
medical  services  under the AT&T Medical Plans for 1996 ("HMO  Agreements")  in
existence as of the date of this  Agreement to permit Lucent to  participate  in
the terms and conditions of such HMO Agreements,  in each case, from Immediately
after  the  Distribution  Date  until  December  31,  1996.  AT&T  shall use its
reasonable best efforts to cause all HMO Agreements into which AT&T enters after
the date of this  Agreement  but  before the Close of the  Distribution  Date to
allow Lucent to  participate  in the terms and conditions of such HMO Agreements
from Immediately after the Distribution Date until December 31, 1996 on the same
basis as AT&T.

                           (ii) AT&T shall have the right to
determine, and
shall promptly notify Lucent of, the manner in which Lucent's  participation  in
the terms and  conditions  of all HMO  Agreements  as set forth  above  shall be
effectuated.  The  permissible  ways  in  which  Lucent's  participation  may be
effectuated include automatically making Lucent a party to the HMO Agreements or
obligating  the HMOs to enter  into  letter  agreements  with  Lucent  which are
identical to the HMO  Agreements.  Such terms and  conditions  shall include the
financial  and  termination  provisions  of the HMO  Agreements.  Lucent  hereby
authorizes  AT&T  to act on its  behalf  to  extend  to  Lucent  the  terms  and
conditions of the HMO Agreements. Lucent shall fully cooperate with AT&T in such
efforts,  and  Lucent  shall  not  perform  any act,  including  discussing  any
alternative  arrangements  with any  third-party,  that would  prejudice  AT&T's
efforts.





<PAGE>

                           (iii) If AT&T determines that it will
not be
successful in negotiating arrangements that will permit compliance with Sections
5.7(c)(i) and  5.7(c)(ii),  AT&T shall so notify Lucent  promptly,  but no event
later than July 20, 1996, and after such notification,  Lucent shall be released
from the restriction  contained in the last sentence of Section  5.7(c)(ii).  In
such case,  Lucent shall enter into letter  agreements  with one or more HMOs to
provide  benefits under the Lucent Medical Plans, at least through  December 31,
1996, in the geographic area serviced by the HMOs covered by AT&T's notice. AT&T
shall,  if  requested  by Lucent  and  permitted  by the HMOs,  arrange  for the
continued  provision  under its HMO  Agreements  of medical  services  to Lucent
Medical Plan  participants  from Immediately after the Distribution Date through
December 31, 1996,  and Lucent shall bear all costs incurred by AT&T to continue
such services.

                           (iv) Notwithstanding anything in this
Article V to
the contrary,  Lucent shall have the sole  discretion to determine which HMOs to
offer to the  participants  in the Lucent  Medical Plans for 1997 and subsequent
years,  and all HMO  Agreements  in which Lucent  participates  pursuant to this
Section  5.7(c)  shall  provide  Lucent  with  the  right  to  discontinue   its
participation effective January 1, 1997.

                  (d) EFFECT OF CHANGE IN RATES. AT&T and Lucent shall use their
reasonable  best  efforts  to  cause  each  of the  insurance  companies,  HMOs,
point-of-service  vendors and third-party  administrators providing services and
benefits  under the AT&T  Health and  Welfare  Plans and the  Lucent  Health and
Welfare Plans to maintain the premium and/or  administrative  rates based on the
aggregate  number of  participants in both the AT&T Health and Welfare Plans and
the Lucent Health and Welfare Plans through the  expiration of the financial fee
or rate guarantees in effect as of the Close of the Distribution  Date under the
respective ASO Contracts,  Group Insurance Policies, and HMO Agreements.  To the
extent they are not successful in such efforts,  AT&T and Lucent shall each bear
the revised  premium or  administrative  rates  attributable  to the individuals
covered by their respective Health and Welfare Plans.

         5.8 PROCEDURES FOR AMENDMENTS TO PLANS, PLAN DESIGNS,
ADMINISTRATIVE
PRACTICES, AND VENDOR CONTRACTS.

                  (a) AMENDMENTS TO PLAN DOCUMENTS.  From Immediately  after the
Distribution Date through December 31, 1998, no amendment to any AT&T Health and
Welfare Plan or Lucent  Health and Welfare  Plan shall be  effective  unless the
party  intending  to amend its Health and Welfare  Plan has: (i) given the other
party  written  notice of the intention to amend,  accompanied  by a copy of the
proposed  amendment,  at  least 30 days in  advance  of the  earlier  of (A) the
proposed amendment  effective date, or (B) the proposed amendment adoption date;

third-party  administrators,  insurance  companies  and other vendors and passed
through to one or both of the parties;  and (iii)  certified to the other party,
and  provided  to the other  party the written  concurrence  of all  third-party
administrators,  insurance  companies  and other vendors  providing  services in
connection  with such Plan, that (after taking into account the effect of clause
(ii))  the  proposed  amendment  to the  Health  and  Welfare  Plan will have no
material  adverse  impact  (financial,   administrative  or  otherwise)  on  the
corresponding Health and Welfare Plan sponsored by the other party.

                           (ii) Neither AT&T nor Lucent shall make
any Change
unless the party  intending  to make the Change  has:  (A) given the other party

taking into account the effect of clause (B)) the  proposed  Change will have no
material  adverse  impact  (financial,   administrative  or  otherwise)  on  the
corresponding Health and Welfare Plan sponsored by the other party.

                           (iii) SUBMISSION TO HEALTH, WELFARE AND

for approval of the Change,  accompanied by a written description of the Change,
to the HWLI  Committee.  If such a request is made,  the  desired  Change may be
implemented only after the Change is approved in writing by the HWLI Committee.

                  (c) EMPLOYEE CONTRIBUTIONS.  Notwithstanding the provisions of
Sections  5.8(a) and 5.8(b),  as of the first  January 1 after the  Distribution

<PAGE>

strategic  oversight  and direction of the cohesive  administration  of the AT&T
Health and Welfare  Plans and the Lucent Health and Welfare  Plans.  Issues that
cannot be resolved  by the HWLI  Committee  shall be decided,  at the request of
either  party,  by the  Executive  Oversight  Committee  comprised of the Lucent
Senior   Vice    President-Human    Resources   and   the   AT&T   Senior   Vice
President-Benefits and Compensation.

         5.10 AT&T SICKNESS AND ACCIDENT DISABILITY, LONG TERM
DISABILITY AND
PENSION DISABILITY BENEFITS.

                  (a) ADMINISTRATION OF AT&T SADBP CLAIMS. AT&T shall administer
claims  incurred  under  the  AT&T  SADBP  by  Transferred  Individuals,  Lucent
Individuals  and other  employees and former  employees of Lucent and the Lucent
Entities on or after the Participation Commencement Date but before the Close of
the Distribution  Date, to the extent such claims are not administered by Lucent
pursuant  to the  terms  of the  AT&T  SADBP  as in  effect  on the date of this
Agreement.  Any  determination  made or  settlements  entered  into by AT&T with
respect to such claims shall be final and binding. If claims incurred before the
Close of the Distribution Date under the AT&T SADBP by Transferred  Individuals,
Lucent  Individuals and other  employees and former  employees of Lucent and the
Lucent Entities were administered by Lucent before the Close of the Distribution
Date, such claims shall continue to be administered by Lucent after the Close of
the Distribution Date, unless outsourced pursuant to Section 5.10(b). AT&T shall
transfer  to  Lucent,   effective   Immediately  after  the  Distribution  Date,
responsibility for administering all claims incurred by Transferred Individuals,
Lucent  Individuals and other  employees and former  employees of Lucent and the
Lucent Entities before the Close of the Distribution  Date that are administered
by AT&T as of the Close of the Distribution  Date.  Lucent shall administer such
claims in the same manner,  and using the same methods and  procedures,  as AT&T
used  in  administering  such  claims.  Lucent  shall  have  sole  discretionary
authority  to make any  necessary  determinations  with  respect to such claims,
including entering into settlements with respect to such claims.

                  (b)  OUTSOURCING OF CLAIMS.  AT&T,  pursuant to its Disability

administrator or insurance company to administer  ("outsource")  claims incurred
under the AT&T SADBP that are being  administered  by AT&T  pursuant  to Section
5.10(a), claims incurred under the AT&T LTD Plans, and claims incurred under the
pension  disability  provisions  of the AT&T  Pension  Plans,  including  claims
incurred by Transferred Individuals,  Lucent Individuals and other employees and
former  employees  of Lucent  and the  Lucent  Entities  before the Close of the
Distribution Date. AT&T may determine the manner and extent of such outsourcing,
including the selection of one or more third-party  administrators  or insurance
companies  and the ability to transfer the  liability  for such claims to one or
more independent  insurance companies.  AT&T shall promptly notify Lucent of its
intent to outsource  such claims,  and the material  terms and  condition of the
outsourcing,  before the effective date thereof.  Lucent shall have the right to
notify AT&T,  within a reasonable  period of time after Lucent  receives  AT&T's
notice of intent to outsource, of Lucent's desire to participate in the proposed
outsourcing.  If Lucent gives such notice,  all claims  incurred by  Transferred
Individuals,  Lucent  Individuals  and other  employees and former  employees of
Lucent and the Lucent  Entities before the Close of the  Distribution  Date that
are  administered by Lucent pursuant to Section 5.10(a) shall be included in the
proposed  outsourcing.  In the  event  Lucent  elects  to  participate  in  such
outsourcing,  Lucent  shall  be  bound  by  the  terms  and  conditions  thereof
(including  all   consequences   of  any  transfer  of  liability)  and  to  any
determinations  and settlements  entered into by the  third-party  administrator
pursuant thereto.

solely  be  responsible  for  administering  compliance  with  the  health  care

plans, and, with respect to Transferred Individuals, the AT&T Health and Welfare
Plans.

responsible for administering compliance with the AT&T Leave of Absence Programs

FMLA, respectively.

                  (b) Effective  Immediately  after the  Distribution  Date: (i)

such leaves that are to commence after the  Distribution  Date; (iii) Lucent and
each Lucent  Entity  shall be solely  responsible  for  administering  leaves of
absence  and  compliance  with FMLA with  respect to their  employees;  and (iv)
Lucent  and each  Lucent  Entity  shall  recognize  all  periods  of  service of
Transferred  Individuals  with AT&T or an AT&T  Entity,  as  applicable,  to the
extent such service is  recognized  by AT&T for the purpose of  eligibility  for
leave entitlement  under the AT&T Leave of Absence Programs and FMLA;  provided,
that no duplication of benefits shall be required by the foregoing.

                  (c) As soon as  administratively  possible  after the Close of

previously to Lucent or a Lucent Entity.

        5.15  AT&T WORKERS' COMPENSATION PROGRAM.

                          (a) ADMINISTRATION OF CLAIMS.

                           (i) Through the Close of the
Distribution Date or
such earlier date as may be agreed by AT&T and Lucent,  (A) AT&T shall  continue
to be  responsible  for the  administration  of all claims that (1) are, or have
been,  incurred under the AT&T WCP before the Close of the Distribution  Date by
Transferred  Individuals,  Lucent  Individuals  and other  employees  and former
employees  of  Lucent  and  the  Lucent  Entities   through  the  Close  of  the
Distribution   Date  ("Lucent  WCP  Claims")  and  (2)  have  been  historically
administered by AT&T or its insurance company,  and (B) Lucent shall continue to
be responsible  for the  administration  of all Lucent WCP Claims that have been
historically administered by the Lucent Business.

                           (ii) Effective immediately after the
Distribution
Date or such earlier date as may be agreed by AT&T and Lucent, (A) Lucent shall,
to the extent Legally  Permissible  (as defined  below),  be responsible for the
administration  of all Lucent WCP Claims,  whether those claims were  previously
administered  by AT&T or  Lucent,  and (B)  AT&T  shall be  responsible  for the
administration  of all Lucent WCP Claims not  administered by Lucent pursuant to
clause (A), whether previously  administered by AT&T or Lucent and whether under
the self-insured or insured portion of the AT&T WCP. Any determination  made, or
settlement  entered into, by either party or its insurance  company with respect
to Lucent WCP Claims for which it is administratively responsible shall be final
and binding upon the other party.

                           (iii) Each party shall fully cooperate
with the other
with  respect to the  administration  and  reporting  of Lucent WCP Claims,  the
payment of Lucent WCP Claims  determined to be payable,  and the transfer of the
administration  of any Lucent WCP Claims to the other party as determined  under
Section  5.15(a)(ii).  Either party shall have the right to  "outsource"  (i.e.,
transfer the  administration  of claims to a third party  administrator or cause
claims to be paid through  insurance) any and all Lucent WCP Claims for which it
is administratively responsible.

                           (iv) For purposes of this Section
5.15(a), "Legally
Permissible" shall be determined on a state-by-state basis, and
shall mean that
administration of Lucent




<PAGE>

WCP  Claims by Lucent  both (A) is  permissible  under  the  applicable  state's
workers'  compensation  laws (taking into account all relevant facts,  including
that Lucent may have a  self-insurance  certificate in that state) and (B) would
not have a material adverse effect on AT&T's  self-insurance  certificate within
that state.  If it is  determined  that,  in a particular  state,  it is Legally
Permissible  for Lucent to  administer  Lucent WCP Claims,  then Lucent shall be
responsible  for the  administration  of all Lucent WCP Claims  incurred in that
state, whether previously administered by AT&T, Lucent, or an insurance company.
If it is determined that, in a particular  state, it is not Legally  Permissible
for Lucent to administer  Lucent WCP Claims,  then AT&T shall be responsible for
the  administration  of all Lucent WCP Claims  incurred in that  state,  whether
previously administered by AT&T, Lucent, or an insurance company.

                           (b) SELF-INSURANCE STATUS.

                           (i) AT&T shall amend its certificates of
self-insurance  with respect to workers'  compensation  and any applicable group
insurance  policies to include Lucent until the Close of the Distribution  Date,
and Lucent shall fully  cooperate  with AT&T in obtaining such  amendments.  All
costs  incurred  by  AT&T in  amending  such  certificates  or  group  insurance
policies,  including  filing  fees,  adjustments  of  security  and excess  loss
policies and amendment of safety  programs,  shall be shared equally by AT&T and
Lucent.  AT&T shall use its  reasonable  best  efforts to obtain  self-insurance
status for workers'  compensation  for Lucent  effective  Immediately  after the
Distribution  Date in each jurisdiction in which Lucent conducts business and in
which AT&T is self-insured, if AT&T determines that such status is beneficial to
Lucent.  Lucent  hereby  authorizes  AT&T  to take  all  actions  necessary  and
appropriate on its behalf in order to obtain such self-insurance status.

                           (ii) AT&T shall also arrange a
contingent insured or
other arrangement for payment of workers' compensation claims, into which Lucent
shall enter if and to the extent that AT&T fails to obtain  self-insured  status
for Lucent as provided in Section 5.15(b)(i), unless Lucent obtains another such
arrangement that is effective  Immediately after the Distribution Date, in which
event Lucent shall reimburse AT&T for any expenses incurred by AT&T in procuring
such contingent arrangement.

                  (c)  INSURANCE POLICY.

                           (i) In the event the workers'
compensation insurance
policy that AT&T maintains  under the AT&T WCP expires  before the  Distribution
Date,  AT&T shall use its  reasonable  best  efforts to renew such policy and to
cause the issuing  insurance  company to issue a separate  policy to Lucent.  If
AT&T is not  able to  cause  such  insurance  company  to  issue  such  separate
insurance  policy,  Lucent  shall use its  reasonable  best efforts to procure a
separate  policy  from  another  insurance  company or to obtain  self-insurance
status,  and AT&T shall use its  reasonable  best  efforts to  continue to cover
Lucent  under its  renewed  policy  until the  earlier  of (A) the date on which
Lucent's application for such self-insurance  status is approved or (B) the date
on which a separate  insurance policy is procured.  Lucent shall compensate AT&T
for all costs incurred by AT&T to continue such coverage. Any claims incurred by
Transferred  Individuals  after the Close of the Distribution  Date that will be
covered under and during any such  continuation  of coverage shall be treated as
being  incurred  before  the  Close of the  Distribution  Date for  purposes  of
determining the party responsible for the administration of benefits.





<PAGE>

                           (ii) AT&T shall use its best effort to
maintain the
premium rates for all workers' compensation insurance policies for both AT&T and
Lucent in effect for periods  through the Close of the  Distribution  Date to be
based  on  the  aggregate  number  of  employees   covered  under  the  workers'
compensation  insurance policies of both AT&T and Lucent. Any premiums due under
the separate workers'  compensation  insurance issued to Lucent shall be payable
by Lucent.

         5.16 AMERICAN TRANSTECH INC. AND BENEFIT DIRECTIONS
ENROLLMENT CENTER.
AT&T shall cause American Transtech Inc. to enter into an
agreement with Lucent
for the provision of data and enrollment services and customer
service for
enrollment and eligibility matters through the 1996 fall open
enrollment period
using the Benefit Directions Enrollment Center (the "BDEC") and
the Benefit
Direction System (the "BDS") database. Such services shall be
provided by
American Transtech Inc. to Lucent on terms and conditions and at
prices
comparable to those on which American Transtech Inc. provides
similar services
to AT&T.

        5.17 AT&T EMPLOYEE ASSISTANCE PROGRAM.  Effective  Immediately after the
Distribution Date, Lucent shall either (a) provide a centralized Lucent Employee
Assistance  Program  staff to provide  case  management  services  for  chemical
dependency/substance abuse treatments to Transferred Individuals or (b) contract
with the mental health network vendor used by AT&T to provide such services.  As
of the Close of the  Distribution  Date,  the AT&T Employee  Assistance  Program
shall cease to have any  responsibility to provide case management  services for
any Transferred Individuals' chemical dependency/substance abuse treatments.

        5.18 AT&T WORK AND FAMILY PROGRAM.  Before the Close of the Distribution
Date,  AT&T and Lucent shall use their  reasonable  best efforts to agree on the
manner  in  which  the  Work and  Family  Program,  including  the  Family  Care
Development Fund, will be jointly funded,  operated and  administered.  Until an
agreement is reached,  AT&T will have sole  responsibility  for  determining the
1996 grant payments to be made under the occupational and management Family Care
Development Fund. After an agreement is reached,  but no later than the Close of
the Distribution Date, Lucent will have sole discretion to determine whether and
at what rate to make payments for the Lucent Fund for Management  Employees.  In
addition,  Lucent will have sole discretion for  administering the Lucent Family
Development Fund Program,  provided that it funds its proportionate share of the
grants  required  by the  National  AT&T/CWA/IBEW  Memorandum  of  Understanding
executed by AT&T and the CWA and IBEW as of May 31,  1992 (the "1992  Collective
Bargaining  Agreement") and the Collective Bargaining Agreement.  The share will
be determined in accordance  with a methodology  agreed upon by AT&T and Lucent,
and if they fail to agree upon a methodology,  Lucent's allocable share shall be
that  portion of the total of such  grants that bears the same  relationship  to
such  total  grants as the  number of Lucent  Individuals  who are  occupational
employees  bears to total number of  occupational  employees  of AT&T,  the AT&T
Entities,  Lucent and the Lucent Entities as of the  Participation  Commencement
Date.  Until  all  of  the  foregoing  obligations  under  the  1992  Collective
Bargaining   Agreement  and  the  Collective   Bargaining  Agreement  have  been
satisfied,  Lucent will  provide  AT&T with  quarterly  reports of  occupational
grants funded.  Before the Close of the  Distribution  Date,  AT&T shall use its
reasonable  best efforts to cause its agreement with its Work and Family vendors
to permit Lucent to participate  in the terms and conditions of such  agreements
until the  expiration  of the  agreements.  These  efforts  shall  substantially
conform to the guidelines set forth in Section 5.7(a) as if such agreements were
ASO Contracts.




<PAGE>

        5.19 WORLD WIDE WEB. Before the Close of the Distribution Date, AT&T and
Lucent  shall  jointly  continue to explore  (including  by  participation  in a
testing program) the feasibility of offering participants in their Plans on-line
computer access to the  point-of-service  provider  directories,  fee schedules,
enrollment and other benefit communication materials through the AT&T customized
Internet  World Wide Web developed by AT&T Bell  Laboratories  and a third-party
vendor.  Lucent  shall have the right to offer  Lucent Plan  participants  these
on-line  computer  services after the  Distribution  Date,  provided that Lucent
exercises  this right by giving written notice of its intent to do so to AT&T on
or before  the  Distribution  Date.  If the  portion  of AT&T Bell  Laboratories
responsible for developing and  maintaining  the AT&T customized  Internet World
Wide Web is  transferred to Lucent  pursuant to the Separation and  Distribution
Agreement, AT&T shall have the right to use, and Lucent agrees to maintain, this
service  pursuant to a contract  entered into between AT&T and Lucent as soon as
practicable  after the Close of the  Distribution  Date.  If the portion of AT&T
Bell Laboratories responsible for developing and maintaining the AT&T customized
Internet  World  Wide Web  remains  with AT&T  pursuant  to the  Separation  and
Distribution  Agreement,  Lucent shall have the right to use, and AT&T agrees to
maintain,  this  service  pursuant to a contract  entered  into between AT&T and
Lucent as soon as practicable after the Close of the Distribution Date.

        5.20  UNEMPLOYMENT INSURANCE TAX MANAGEMENT PROGRAM.

                  (a) AT&T  shall  cause  Lucent  to be  covered  under the AT&T
Unemployment   Insurance   Tax   Management   Program  from  the   Participation
Commencement  Date  through the Close of the  Distribution  Date.  Lucent  shall
reimburse AT&T for its allocable share of fees paid by AT&T to its  unemployment
insurance tax management vendor for services rendered during such period. Lucent
shall  cooperate  with the  unemployment  insurance  tax  management  vendor  by
providing  information in its possession that is necessary for administration of
the AT&T Unemployment Insurance Tax Management Program.

                  (b)  Before  the   Distribution   Date,  AT&T  shall  use  its
reasonable best efforts to cause its agreement with its  unemployment  insurance
tax management  vendor and any successor thereto to permit Lucent to participate
in the  terms and  conditions  of such  agreements  from  Immediately  after the
Distribution  Date through  June 30, 1997.  These  efforts  shall  substantially
conform to the guidelines set forth in Section 5.7(a) as if such agreements were
ASO  Contracts.  AT&T  shall  use its  reasonable  best  efforts  to cause  such
agreements to provide that Lucent's  participation shall include  administration
of all  unemployment  compensation  claims of  Transferred  Individuals,  Lucent
Individuals  and other  employees and former  employees of Lucent and the Lucent
Entities,  regardless of whether such claims were filed before, on, or after the
Distribution Date.

Transferred  Individuals  under the AT&T Health and Welfare Plans and apply such

period or periods for which such  elections are by their terms  applicable.  The
transfer or other movement of employment  from AT&T to Lucent at any time before

"status change" under the AT&T Health and Welfare Plans or the Lucent Health and
Welfare Plans.

cause the AT&T Health and Welfare Plans to permit  eligible AT&T and AT&T Entity

the terms and conditions of the applicable  Health and Welfare Plans.  Effective

employees or lawful spouse  retirees may be covered under both the Lucent Health
and  Welfare  Plans and the AT&T  Health and  Welfare  Plans,  and the  benefits
provided under both plans shall be coordinated  pursuant to the applicable terms
and conditions of the  respective  Health and Welfare Plans in effect as of such
date and thereafter as amended from time to time.

                           (ii) HCFA DATA MATCH. Immediately after
the
Distribution Date, Lucent shall assume all Liabilities  relating to, arising out
of or resulting from claims verified by AT&T or Lucent under the HCFA data match

Individuals.  Lucent  shall  not  change  any  employee  identification  numbers
assigned  by AT&T  without  notifying  AT&T of the change  and the new  Employee

negotiations between its health plan carriers or claims  administrators and HCFA
before the end of the  Occupational  Transition  Period,  Lucent  shall have the
right to participate in such negotiations.

insurance contract,  or HMO letter agreement associated with a Lucent Health and
Welfare Plan, (b) become a  self-insured  entity for the purposes of one or more
Lucent Health and Welfare Plans,  (c) assume all or a portion of the liabilities
or administrative  responsibilities for benefits which arose before the Close of

expressly assumed by Lucent pursuant to the terms of this Agreement, or (d) take
any other action, extend any coverage, assume any other liability or fulfill any
other  responsibility  that Lucent would otherwise be required to take under the
terms of this Article V, unless it is clear from the context that the particular
reference is not intended to include a Lucent  Entity.  In all such instances in
which a reference in this Article V to "Lucent" includes a reference to a Lucent
Entity,  Lucent shall be responsible to AT&T for ensuring that the Lucent Entity
complies  with  the  applicable  terms  of this  Agreement  and the  Transferred
Individuals  allocated  to such  Lucent  Entity  shall have the same  rights and
entitlements  to benefits under the  applicable  Lucent Health and Welfare Plans
that the  Transferred  Individual  would have had if he or she had instead  been
allocated to Lucent.

reasonable  best  efforts  to  obtain,  or cause to be  obtained,  to the extent
necessary,  the written consent of each Transferred Individual who is a party to
an Individual Agreement and/or a participant in any AT&T Executive Benefit Plan,

Non-Employee  Director  Plan,  to the  treatment of such  Individual  Agreement,
Executive Benefit Plan and/or AT&T Non-Employee Director Plan, as applicable, in
accordance  with this Article VI,  including  the  assumption  by Lucent and the
Lucent  Entities,  of sole  responsibility  for, and the release of AT&T and the
AT&T Entities from, all  Liabilities  thereunder;  provided,  that no failure to
seek or to obtain any such consent shall have any effect upon the obligations of
Lucent and the Lucent Entities with respect to such Liabilities.

         6.3 AT&T SHORT TERM INCENTIVE  PLAN.  Lucent shall be
responsible  for
determining,  with respect to all Awards that would  otherwise be

                  (a) TRANSFERRED INDIVIDUALS WHO ARE ACTIVE
EMPLOYEES OF
LUCENT.

                           (i) STOCK OPTIONS. Lucent shall cause
each Award
consisting  of an  AT&T  Option  that  is  outstanding  as of the  Close  of the
Distribution  Date (or, in the case of a Lucent  Administrative  Employee,  such
later  date as he or she  becomes  a  Transferred  Individual)  and is held by a
Transferred  Individual who, as of the  Distribution  Date (or, in the case of a
Lucent  Administrative  Employee,  such  later  date  as he  or  she  becomes  a
Transferred  Individual),  is an active  employee of or on leave of absence from
Lucent  or a Lucent  Entity  to be  replaced,  effective  Immediately  after the
Distribution  Date,  with a Lucent Option.  Such Lucent Option shall provide for
the purchase of a number of shares of Lucent Common Stock equal to the number of
shares of AT&T Common  Stock  subject to such AT&T Option as of the Close of the
Distribution Date, multiplied by the Ratio, and then rounded down to the nearest
whole share.  Lucent shall pay to the holder of such  replacement  Award, at the
time of such  replacement,  cash in lieu of any  fractional  share  equal to the
product of (A) the fraction  represented by such fractional  share times (B) (1)
the excess of the Lucent Stock Value over (2) the  per-share  exercise  price of
such AT&T Option as of the Close of the Distribution  Date divided by the Ratio.
The  per-share  exercise  price of such Lucent  Option shall equal the per-share
exercise  price of such AT&T  Option as of the  Close of the  Distribution  Date
divided by the Ratio.  Each such Lucent  Option  shall  otherwise  have the same
terms and conditions as were applicable to the  corresponding  AT&T Option as of
the Close of the  Distribution  Date,  except  that  references  to AT&T and its
Affiliates shall be amended to refer to Lucent and its Affiliates.

                           (ii) PERFORMANCE SHARES AND STOCK
UNITS. Lucent shall
cause each Award consisting of AT&T performance  shares or AT&T stock units that
is  outstanding as of the Close of the  Distribution  Date (or, in the case of a
Lucent  Administrative  Employee,  such  later  date  as he  or  she  becomes  a
Transferred  Individual) and is held by a Transferred  Individual who, as of the
Distribution  Date (or, in the case of a Lucent  Administrative  Employee,  such
later date as he or she becomes a Transferred Individual), is an active employee
of or on  leave of  absence  from  Lucent  or a Lucent  Entity  to be  replaced,
effective  Immediately after the Distribution Date, with a new performance share
award or a new stock unit award,  as the case may be,  consisting of a number of
Lucent  performance  shares or Lucent stock units,  as the case may be, equal to
the number of AT&T  performance  shares or AT&T stock units, as the case may be,
constituting such Award immediately before the Distribution Date,  multiplied by
the Ratio, and then rounded down to the nearest whole share. Lucent shall pay to
the holder of such replacement  Award, at the time of such replacement,  cash in
lieu of any  fractional  share  based  on the  Lucent  Stock  Value.  Each  such
replacement  Award shall  otherwise  have the same terms and  conditions as were
applicable to the  corresponding  AT&T Award as of the Close of the Distribution
Date,  except that  references  to AT&T and its  Affiliates  shall be amended to
refer to Lucent and its Affiliates  and dividend  equivalent  payments,  if any,
shall be payable  after the Close of the  Distribution  Date with  reference  to
dividends on Lucent Common Stock.

                           (iii) RESTRICTED STOCK AND RESTRICTED
STOCK UNITS.
Lucent shall cause each Award that consists of non-vested  restricted  shares of
AT&T Common Stock or  restricted  stock units  relating to shares of AT&T Common
Stock that is outstanding as of the Close of the  Distribution  Date (or, in the
case of a Lucent Administrative Employee, such later date as he or she becomes a
Transferred  Individual) and is held by a Transferred  Individual who, as of the
Close of the  Distribution  Date  (or,  in the  case of a Lucent  Administrative
Employee, such later date as he or she becomes a Transferred Individual),  is an
active  employee of or on leave of absence from Lucent or a Lucent  Entity to be
replaced,  effective  Immediately after the Distribution  Date, with a new Award
consisting of a number




<PAGE>

of non-vested  restricted  shares of Lucent Common Stock and/or restricted stock
units  relating  to  shares  of  Lucent  Common  Stock  equal to the  number  of
non-vested  restricted  shares or  restricted  stock units of AT&T Common  Stock
constituting  such Award as of the Close of the Distribution  Date multiplied by
the Ratio, and then rounded down to the nearest whole share. Lucent shall pay to
the holder of such replacement  Award, at the time of such replacement,  cash in
lieu of any  fractional  share  based  on the  Lucent  Stock  Value.  Each  such
replacement  Award shall  otherwise  have the same terms and  conditions as were
applicable to the  corresponding  AT&T Award as of the Close of the Distribution
Date,  except that  references  to AT&T and its  Affiliates  shall be amended to
refer to Lucent and its Affiliates  and dividend  equivalent  payments,  if any,
shall be payable  after the  Distribution  Date with  reference  to dividends on
Lucent Common Stock.

                           (iv) SPECIAL PAYMENT. On the thirtieth
day following
the  Distribution  Date, AT&T shall pay to Lucent an amount in cash equal to the
excess,  if any,  of (a) the Gross Value of the  Assumed  Stock  Awards over (b)
seven percent (7%) of the Aggregate Lucent Stock Value.

                  (b) TRANSFERRED  INDIVIDUALS  WHO ARE NOT ACTIVE  EMPLOYEES OF
LUCENT. Each outstanding Award that is held by a Transferred  Individual who, as
of  the  Close  of  the  Distribution   Date  (or,  in  the  case  of  a  Lucent
Administrative  Employee,  such  later date as he or she  becomes a  Transferred
Individual),  is not an active employee of or on leave of absence from Lucent or
a Lucent Entity shall remain outstanding Immediately after the Distribution Date
in accordance  with its terms as applicable as of the Close of the  Distribution
Date,  subject to such  adjustments as may be applicable to  outstanding  Awards
held by individuals  who remain active  employees of or on leave of absence from
AT&T or an AT&T Entity after the Distribution Date.

         6.5  AT&T  SENIOR  MANAGEMENT   INCENTIVE  AWARD  DEFERRAL  PLAN.  Each
Transferred Individual who has a deferred AT&T share unit account under the AT&T
Deferral Plan shall be permitted an irrevocable election to have the share units
in such  account  converted  to their  cash  value and  transferred  to the cash
account under the AT&T Deferral Plan, which election shall be made in accordance
with  procedures  established  by  AT&T,  in its  sole  discretion,  before  and
effective  as of the  Close of the  Distribution  Date.  Immediately  after  the
Distribution  Date, the balance of any Transferred  Individual in either an AT&T
share unit  account or a cash  account  under the AT&T  Deferral  Plan as of the
Close of the  Distribution  Date  shall be  transferred  to a Lucent  share unit
account or cash account,  respectively,  under the Lucent  Deferral Plan, with a
number of Lucent  share  units equal to the number of AT&T share units under the
AT&T Deferral Plan as of the Close of the  Distribution  Date  multiplied by the
Ratio.

         6.6  NON-EMPLOYEE DIRECTOR BENEFITS.

                  (a)  NON-EMPLOYEE  DIRECTOR  PLANS.  As of the  Closing  Date,
Lucent shall assume and be solely responsible for all Liabilities under the AT&T
Non-Employee Director Plans to or relating to Lucent Non-Employee Directors.

                  (b) DEFERRED  COMPENSATION  PLAN FOR  NON-EMPLOYEE  DIRECTORS.
Each Lucent  Non-Employee  Director  who has a deferred  AT&T share unit account
under the AT&T Deferred  Compensation  Plan for Non-Employee  Directors shall be
permitted  an  irrevocable  election  to have the  share  units in such  account
converted to their cash value and




<PAGE>

transferred  to the cash account under the AT&T Deferred  Compensation  Plan for
Non-Employee  Directors,  which  election  shall  be  made  in  accordance  with
procedures established by AT&T, in its sole discretion,  before and effective as
of  the  Closing  Date.  As of the  Closing  Date,  the  balance  of any  Lucent
Non-Employee  Director  in either an AT&T share unit  account or a cash  account
under the AT&T Deferred  Compensation  Plan for Non-Employee  Directors shall be
transferred to a Lucent share unit account or cash account, respectively,  under
the Lucent Deferred Compensation Plan for Non-Employee Directors,  with a number
of Lucent  share  units  equal to the number of AT&T share  units under the AT&T
Deferred  Compensation  Plan for  Non-Employee  Directors as of the Closing Date
multiplied by the amount  obtained by dividing (A) the average of the daily high
and low  per-share  prices of the AT&T Common Stock as listed on the NYSE during
each of the five trading days  Immediately  after the Closing  Date,  by (B) the
average of the daily high and low per-share prices of the Lucent Common Stock as
listed on the NYSE during each of the five  trading days  Immediately  after the
Closing Date.

         6.7  NON-COMPETITION GUIDELINES.

                  (a) AT&T NON-COMPETITION GUIDELINE.  Effective as of the Close
of the Distribution Date, AT&T shall cause the AT&T Non-Competition Guideline to
be amended to provide that until the end of the  eighteenth  calendar month that
ends after the Close of the Distribution Date,  employment by Lucent or a Lucent
Entity shall not be a violation of the guideline.

                  (b) LUCENT  NON-COMPETITION  GUIDELINE.  Effective Immediately
after the Distribution  Date,  Lucent shall adopt a  non-competition  guideline,
applicable  to  employees of Lucent and the Lucent  Entities  who are  similarly
situated to those employees of AT&T and the AT&T Entities who are subject to the
AT&T  Non-Competition  Guideline,  which guideline shall expressly  provide that
until the end of the eighteenth  calendar month that ends after the Close of the
Distribution  Date,  employment by AT&T shall not  constitute a violation of the
guideline.

                  (c) CONFIDENTIALITY AND PROPRIETARY INFORMATION.  No provision
of the  Separation  and  Distribution  Agreement  shall be deemed to release any
individual  for any  violation  of the  AT&T  Non-Competition  Guideline  or any
agreement or policy  pertaining to  confidential  or proprietary  information of
AT&T or any of its Affiliates, or otherwise relieve any individual of his or her
obligations under such Guideline or any such agreement or policy.

         6.8 RABBI TRUST AND CORPORATE-OWNED LIFE INSURANCE.


                  (a)  ESTABLISHMENT  OF MIRROR RABBI TRUST.  Effective no later
than Immediately after the Distribution  Date, Lucent shall establish,  or cause
to be  established,  the Lucent Rabbi Trust as a grantor  trust  subject to Code
SectionSection  671 et seq.,  which  shall  be  substantially  identical  in all
Material  Features to the AT&T Rabbi Trust,  other than the  definitions  of the
terms  "potential  change in control"  and  "change in  control."  Lucent  shall
appoint as trustee under the Lucent Rabbi Trust the then-current  trustee of the
AT&T Rabbi Trust.


                  (b) FUNDING OF LUCENT RABBI TRUST.

                           (i) As of the earlier of the Close of
the
Distribution  Date and the date when assets are first transferred or contributed
to the Lucent Rabbi Trust (the "Rabbi





<PAGE>

Trust  Determination  Date"), AT&T shall determine the amount of the liabilities
under the AT&T Executive  Benefits Plans (other than the AT&T Senior  Management
Incentive Award Deferral Plan) that are payable from the AT&T
Rabbi Trust.  AT&T
shall then cause the  trustee of the AT&T Rabbi Trust to transfer to the trustee
of the Lucent  Rabbi  Trust (A) the most  recently  purchased  trust-owned  life
insurance  policy  held by the AT&T Rabbi  Trust if more than one such policy is
then so held (regardless of which entity employs the insured  individuals),  and
(B) if AT&T, in its sole  discretion,  so determines,  all cash then held in the
AT&T Rabbi Trust that is not invested in  trust-owned  life  insurance.  If AT&T
determines (or projects) that  immediately  after such transfer the ratio of the
value of the  assets in the  Lucent  Rabbi  Trust to the  liabilities  under the
Lucent  Executive  Benefit  Plans  (other  than  the  Lucent  Senior  Management
Incentive Award Deferral Plan) that are payable from the Lucent Rabbi Trust will
be less  than the  ratio of the  value of the  assets  in the AT&T  Rabbi  Trust
(before the  allocation of assets to the Lucent Rabbi Trust) to the  liabilities
under the AT&T  Executive  Benefit Plans (other than the AT&T Senior  Management
Incentive  Award  Deferral  Plan) (before the  allocation of  liabilities to the
Lucent Rabbi Trust),  then Lucent shall make an additional  contribution  to the
Lucent  Rabbi Trust from its  general  assets in cash,  simultaneously  with the
transfer of assets from the AT&T Rabbi Trust to the Lucent  Rabbi  Trust,  in an
amount such that,  immediately  following  the  transfer of assets from the AT&T
Rabbi Trust to the Lucent Rabbi  Trust,  the ratio of the value of the assets in
the Lucent Rabbi Trust to the  liabilities  under the Lucent  Executive  Benefit
Plans (other than the Lucent Senior  Management  Incentive  Award Deferral Plan)
will immediately thereafter be equal to the ratio of assets to liabilities under
the AT&T Rabbi Trust  (other than  liabilities  associated  with the AT&T Senior
Management  Incentive Award Deferral Plan) immediately  before the allocation of
assets and  liabilities to the Lucent Rabbi Trust.  For purposes of this Section
6.8(b)(i),  liabilities shall be determined based upon the "Full Funding Amount"
as defined in Section 2.5 of the AT&T Rabbi Trust.

                           (ii) As of the Rabbi Trust
Determination Date, Lucent
and AT&T  shall  identify  the  Transferred  Individuals  and other  individuals
insured by trust-owned  life  insurance  polices held by the trustee of the AT&T
Rabbi Trust and (after any transfers described in Section 6.8(b)(i)) the trustee
of the Lucent  Rabbi  Trust,  and shall share (and shall  cause the  trustees of
their respective Rabbi Trusts to share) such information as may be necessary for
each to determine when and whether such individuals are deceased.

                  (c) CORPORATE-OWNED LIFE INSURANCE. Lucent and AT&T shall take
all actions,  including creating any trust  arrangements  necessary to replicate
the manner in which AT&T has  heretofore  held such  policies,  and executing or
accepting  delivery of any assignments  reasonably  requested by either party or
any insurance company insuring one or more lives under the Corporate-Owned  Life
Insurance,  as may be necessary or appropriate in order to assign those policies
insuring  Transferred  Individuals to Lucent,  effective  Immediately  after the
Distribution Date. If a Corporate-Owned  Life Insurance Policy is so assigned to
Lucent,  Lucent shall assume and be solely responsible for all Liabilities,  and
shall be entitled to all  benefits,  thereunder,  effective as of the earlier of
(i) the  Close of the  Distribution  Date and (ii) the date of such  assignment.
AT&T and Lucent shall continue, liquidate and/or administer such Corporate-Owned
Life Insurance  Policies on terms and  conditions  agreed to by AT&T and Lucent.
Lucent and AT&T shall share all  information  that may be  necessary to identify
the individuals insured by the Corporate-Owned  Life Insurance policies owned by
AT&T and Lucent and to determine when and whether such individuals are deceased.

         6.9 AT&T SPLIT DOLLAR LIFE INSURANCE. AT&T and Lucent
shall take all
actions necessary or appropriate to assign to Lucent, AT&T's
rights and
interests in the Split Dollar




<PAGE>

Life Insurance  policies under the Senior  Management  Individual Life Insurance
Program  and the  Senior  Management  Basic  Life  Insurance  Program  issued by
Metropolitan  Life  Insurance  Company,  Hartford Life  Insurance  Company,  and
Confederation Life Insurance Company (or their successors in interest, including
Pacific Mutual Life  Insurance  Company),  and any additional  split dollar life
insurance  program  that may be  implemented  by AT&T  before  the  Close of the
Distribution   Date,   with  respect  to  Transferred   Individuals,   effective
Immediately  after  the  Distribution  Date,  and  under  the AT&T  Non-Employee
Director  Plans with respect to AT&T  Non-Employee  Directors  who become Lucent
Non-Employee  Directors,  effective as of the Closing Date (such  policies,  the
"Assigned  Split  Dollar   Policies").   Such  actions  shall  include  Lucent's
acceptance of any  collateral  assignments,  policy  endorsements  or such other
documentation  executed by or on behalf of  Transferred  Individuals  and Lucent
Non-Employee  Directors,  or any trustee of any trust to which such individual's
policy rights or incidents of ownership under the Assigned Split Dollar Policies
have  been  assigned,  and  Lucent's  entering  into such  agreements  as may be
necessary  to  fulfill  any  obligations  of AT&T to any  insurance  company  or
insurance  agent or broker under the Assigned  Split Dollar  Policies.  From and
after the date of the  assignment of any Assigned Split Dollar Policy to Lucent,
Lucent shall assume and be solely responsible for all Liabilities,  and shall be
entitled  to all  benefits,  of AT&T  under  such  policy  and under the  Senior
Management Life Insurance  Program,  the Senior  Management Basic Life Insurance
Program,  the AT&T  Non-Employee  Director Plans and any additional split dollar
life  insurance  program that may be implemented by AT&T before the Close of the
Distribution  Date, as the case may be, with respect to such  policies,  and any
related   agreements   entered  into  by   Transferred   Individuals  or  Lucent
Non-Employee Directors.


                                   ARTICLE VII
                             MISCELLANEOUS BENEFITS

         7.1 TRANSFER OF STOCK PURCHASE PLAN RECORDKEEPING
ACCOUNTS. If the AT&T
Stock Purchase Plan is in effect as of the Close of the
Distribution  Date, AT&T
shall cause the recordkeeping accounts under the AT&T Stock Purchase Plan of all
Transferred  Individuals to be transferred,  as of the Close of the Distribution
Date or as soon as  practicable  thereafter,  to,  and  Lucent  shall  cause the
accounts to be accepted by, the recordkeeper for the Lucent Stock Purchase Plan.
Lucent  shall  use  its  reasonable   best  efforts  to  enter  into  agreements
satisfactory to Lucent with the  recordkeeper of the AT&T Stock Purchase Plan to
ensure the transfer and maintenance of the participant records.  Through the end
of the Occupational  Transition  Period,  Lucent shall use a recordkeeper and an
enrollment  vendor  under the Lucent Stock  Purchase  Plan  compatible  with the
recordkeeper and enrollment vendor under the AT&T Stock Purchase Plan.

         7.2  CONCESSION  TELEPHONE  SERVICE.  Effective  Immediately  after the
Distribution  Date  through June 30,  1998,  Lucent shall  continue to provide a
concession  telephone  service program for Transferred  Individuals who are then
retired or who retire on or before June 30, 1998,  which shall be  substantially
identical  in  all  Material  Features  to  the  corresponding  AT&T  concession
telephone service program (provided, that Lucent shall only reimburse or pay for
long-distance services provided by AT&T to such Transferred Individuals).

         7.3  SERVICE ANNIVERSARY AND RETIREMENT AWARD PROGRAM.

                  (a) Before the Close of the Distribution  Date, AT&T shall use
its reasonable best efforts to amend the service anniversary  merchandise vendor
contract in existence as of




<PAGE>

the date of this  Agreement  and  related to the AT&T  Service  Anniversary  and
Retirement Award Program to permit Lucent and the Lucent Entities to participate
in the terms and  conditions of such contract  effective  Immediately  after the
Distribution Date. These efforts shall substantially conform with the guidelines
set forth in Section  5.7(a) as if the service  anniversary  merchandise  vendor
contract were an ASO Contract.

                  (b)  Lucent  and the  Lucent  Entities  may  provide  to their
employees service  anniversary  merchandise bearing the name and/or logo of AT&T
ordered by AT&T before the date of this Agreement and delivered under the Lucent
Service  Anniversary  and Retirement  Award Program to Transferred  Individuals,
Lucent  Individuals and other  employees and former  employees of Lucent and the
Lucent Entities whose service anniversary occurs on or before December 31, 1996,
subject to the terms and conditions of any separate  agreement  between AT&T and
Lucent regarding the use of the corporate names, logos,  service marks and other
intellectual  property  of  AT&T  and an AT&T  Entity.  No  service  anniversary
merchandise bearing the corporate name and/or logo of AT&T shall be delivered to
any Transferred  Individuals,  Lucent  Individuals or other employees and former
employees  of  Lucent  and  the  Lucent  Entities  with  respect  to  a  service
anniversary on or after January 1, 1997,  without the express written consent of
AT&T.

         7.4  SHARES  FOR  GROWTH  PROGRAM.   Effective  Immediately  after  the
Distribution  Date,  Lucent  shall  assume  and be  solely  responsible  for all
Liabilities  relating to, arising out of or resulting from awards to Transferred
Individuals  under the Shares for Growth Program  provided for in the Collective
Bargaining Agreement.  Awards to Transferred Individuals payable after the Close
of the  Distribution  Date shall be made in shares of Lucent Common Stock rather
than shares of AT&T Common  Stock,  and in  determining  the number of shares of
Lucent Common Stock  Transferred  Individuals will receive for such awards,  the
August  1995  reference  price  for a share  of  Lucent  Common  Stock  shall be
calculated  by  dividing  the August  1995  reference  price for a share of AT&T
Common Stock as set forth in the Collective Bargaining Agreement by the Ratio.

         7.5 THEODORE N. VAIL AWARD TRUST  ASSETS.  Lucent shall have the option
to continue to offer the Theodore N. Vail  Memorial  Fund Awards  program to its
employees after the Close of the Distribution  Date,  provided that it exercises
this option by giving  written  notice of its intent to AT&T before the Close of
the  Distribution  Date.  If Lucent  elects to offer the Theodore N. Vail Awards
program,  and it is  determined  by AT&T to be legally  permissible  to transfer
assets from the AT&T  Theodore N. Vail Awards  trust to a trust  established  by
Lucent for purposes of the Lucent  Theodore N. Vail Awards  program,  AT&T shall
transfer from the AT&T  Theodore N. Vail Awards trust to such trust  established
by Lucent  assets  determined by AT&T to have a fair market value that bears the
same  relationship  to the fair  market  value of the total  assets in such AT&T
trust as the  number of  Transferred  Individuals  bears to the total  number of
employees and former employees of AT&T, the AT&T Entities, Lucent and the Lucent
Entities  as of the Close of the  Distribution  Date.  AT&T  shall have the sole
discretion to determine  whether such assets will be  transferred  to the Lucent
trust in the form of AT&T Stock or cash or a combination thereof.

         7.6  1996  MANAGEMENT  INCENTIVE   COMPENSATION   PAYMENTS.   Effective
Immediately  after  the  Distribution  Date,  Lucent  shall be  responsible  for
determining,  with  respect  to company  performance  awards,  unit  performance
awards, and merit awards that would otherwise be payable under AT&T's management
compensation  program to Transferred  Individuals for the 1996 performance year,
(a) the extent to which  established  performance  criteria (as  interpreted  by
Lucent, in its sole discretion, after taking into account the effects




<PAGE>

of the IPO and the Distribution) have been met and (b) the payment
level for
each Transferred Individual.

                                  ARTICLE VIII
                           GENERAL AND ADMINISTRATIVE

         8.1 PAYMENT OF 1996 ADMINISTRATIVE COSTS AND EXPENSES.

                  (a) SHARED  COSTS.  The  estimated  budget for 1996 for AT&T's
Benefits and  Compensation  organization  is set forth on Schedule VII. AT&T and
Lucent shall each be  responsible  for their  allocable  share of such  budgeted
costs as set forth on Schedule VII. Lucent shall pay to AT&T  one-twelfth of its
allocable  share of such  budgeted  costs each  month  during  1996.  AT&T shall
provide,  as  soon as  practicable  after  the  date  of  this  Agreement,  such
information   as  may   reasonably  be  requested  by  Lucent   concerning   the
determination of such budgeted costs.

                  (b) ADDITIONAL UNANTICIPATED EXPENSES. If there are additional
expenses not anticipated in the 1996 budget for AT&T's Benefits and Compensation
organization,  then  Lucent  shall pay to AT&T  one-half  of such  unanticipated
expenses, but only to the extent that the additional expenses are (i) reasonable
and  necessary  and (ii)  incurred  as a direct  result  of,  and solely for the
purpose of, the normal  administration (as currently  projected for 1996) of the
AT&T Plans and the Lucent Plans during 1996. If any  unanticipated  expenses are
incurred  at the  request of Lucent or a Lucent  Entity,  they shall be the sole
responsibility  of Lucent.  Any other  unanticipated  expenses shall be the sole
responsibility of AT&T.

                  (c)  ADMINISTRATIVE  PERSONNEL.  A schedule of the individuals
employed  in  AT&T's  Benefits  and  Compensation  organization  who  have  been
designated  to  become  employees  of  Lucent or a Lucent  Entity  (the  "Lucent
Administrative  Employees")  has been  agreed to by Lucent and AT&T.  The Lucent
Administrative  Employees shall remain on AT&T's payroll until December 31, 1996
unless AT&T and Lucent agree to a different  date. If AT&T and Lucent elect that
the  Lucent  Administrative  Employees  be placed on the Lucent  payroll  before
January  1,  1997,  then  Lucent's  direct  cost  with  respect  to  the  Lucent
Administrative  Employees  (including  salary and loading  for  benefit  related
charges) for each month after they leave AT&T's payroll shall be subtracted from
the monthly amount  payable by Lucent in accordance  with Section  8.1(a).  Such
individuals  shall become  Transferred  Individuals  when they are placed on the
payroll  of  Lucent  or a Lucent  Entity  if such date is after the Close of the
Distribution Date. Regardless of whether the Lucent Administrative Employees are
on the  payroll of AT&T or Lucent or a Lucent  Entity,  they shall be subject to
the supervision of AT&T's Senior Vice President,  Benefits and Compensation,  or
his delegates, through December 31, 1996.

                  (d)   POST-DISTRIBUTION   ADMINISTRATION  IN
1996.  From  the
Distribution  Date  through  December 31, 1996,  AT&T's  Senior Vice  President,
Benefits and  Compensation,  and his staff (including the Lucent  Administrative
Employees) shall have full authority and responsibility to administer the Lucent
Plans to the same  extent as if  AT&T's  Senior  Vice  President,  Benefits  and
Compensation,  and his  staff  were  employees  of  Lucent  or a Lucent  Entity.
Notwithstanding the foregoing,  Lucent shall retain all fiduciary responsibility
for the  administration  of the Lucent Plans and, subject to the need to conform
the  administration  of the AT&T Plans and the Lucent Plans during 1996,  Lucent
shall have the right to




<PAGE>

direct AT&T's Senior Vice President, Benefits and
Compensation,  in the  manner  in  which  it  intends  the
Lucent  Plans  to be
administered.

         8.2 PAYMENT OF LIABILITIES, PLAN EXPENSES AND RELATED
MATTERS.

                  (a) ACTUARIAL AND ACCOUNTING  METHODOLOGIES  AND  ASSUMPTIONS.
For purposes of this Agreement, unless specifically indicated otherwise: (i) all
actuarial methodologies and assumptions used for a particular Plan shall (except
to the  extent  otherwise  determined  by AT&T and  Lucent to be  reasonable  or
necessary) be substantially the same as those used in the actuarial valuation of
that Plan used to determine minimum funding requirements under ERISA Section 302
and Code  Section 412 for 1996,  or, if such Plan is not subject to such minimum
funding  requirements,  used to determine AT&T's deductible  contributions under
Code  Section  419A or, if such Plan is not subject to Code  Section  419A,  the
assumptions used to prepare AT&T's audited financial statements for 1996, as the
case may be; and (ii) the value of plan  assets  shall be the value  established
for purposes of audited  financial  statements of the relevant plan or trust for
the period  ending on the date as of which the  valuation is to be made.  Lucent
Liabilities  relating to,  arising out of or resulting from the status of Lucent
and the Lucent  Entities as  Participating  Companies in AT&T Plans, as provided
for in Section 2.2 and all accruals relating thereto shall be determined by AT&T
using  actuarial  assumptions  and  methodologies  (including  with  respect  to
demographics, medical trends and other relevant factors) determined by AT&T in a
manner  consistent  with  AT&T's  practice  as in  effect  on the  Participation
Commencement  Date and in  conformance  with the  generally  accepted  actuarial
principles  promulgated by the American Academy of Actuaries,  the Code,  ERISA,
and/or generally accepted accounting principles,  as applicable, in each case as
interpreted  by  AT&T  consistent  with  past  practice.   Except  as  otherwise
contemplated by this Agreement or as required by law, all  determinations  as to
the amount or valuation  of any assets of or relating to any AT&T Plan  (whether
or not  such  assets  are  being  transferred  to a Lucent  Plan)  shall be made
pursuant to procedures to be established by the parties before the Closing Date.

                  (b) PAYMENT OF LIABILITIES;  DETERMINATION OF EMPLOYEE STATUS.
Lucent shall pay  directly,  or reimburse  AT&T  promptly  for, all  Liabilities
assumed by it pursuant to this Agreement,  including all compensation payable to
Lucent  Individuals and Transferred  Individuals for services  rendered while in
the employ of AT&T or an AT&T  Entity  before  becoming a Lucent  Individual  or
Transferred Individual,  respectively (to the extent not charged for pursuant to
Section 8.1 or another  Ancillary  Agreement).  To the extent the amount of such
Liabilities is not yet determinable  because the status of individuals as Lucent
Individuals  or  Transferred  Individuals  is  not  yet  determined,  except  as
otherwise  specified  herein or in another  Ancillary  Agreement with respect to
particular Liabilities,  Lucent shall make such payments or reimbursements based
upon AT&T's reasonable estimates of the amounts thereof, and when such status is
determined,  Lucent shall make additional  reimbursements  or payments,  or AT&T
shall reimburse  Lucent, to the extent necessary to reflect the actual amount of
such  Liabilities.  In  determining  the number of individuals in any particular
group of employees described in this Agreement (such as "Transferred Individuals
and Lucent  Individuals"),  no  individual  shall be counted twice (even if, for
example,  he or she is both a Lucent  Individual and a Transferred  Individual).
Determinations of what entity employs or employed a particular  individual shall
be made by reference to the  applicable  legal entity  and/or other  appropriate
accounting code, to the extent possible.

                  (c) CONTRIBUTIONS TO TRUSTS. Lucent shall pay
its share of any
contributions made to any trust maintained in connection with an
AT&T Plan with
respect to any



<PAGE>

period while Lucent or a Lucent Entity is a  Participating  Company in that AT&T
Plan; provided,  however, that Lucent shall not be required to contribute to the
AT&T  Rabbi  Trust  after  the  date of this  Agreement.  Lucent's  share of any
contributions  to the AT&T Health  Benefits  Trust shall be determined  based on
AT&T's  reasonable  estimate of the claims under the AT&T Plans  funded  through
such trust that are paid to or for the benefit of Lucent  Individuals  and other
employees and former  employees of Lucent and the Lucent  Entities,  Transferred
Individuals  and  beneficiaries  and  dependents  thereof,  until a cash benefit
payment  procedure  for daily check  presentments  separately  to Lucent and the
Lucent  Entities for such claims is  implemented,  after which Lucent's share of
such contributions shall be determined based upon such procedure. Lucent's share
of any  contributions  to any other such trust  shall be  determined  by AT&T by
computing  separate  contribution  amounts for AT&T and Lucent, as if Lucent and
the Lucent  Entities  were not  Affiliates  of AT&T and the AT&T  Entities,  but
followed the same funding  policy and used the same funding  assumptions as AT&T
and the AT&T Entities with respect to such trust;  provided,  that if the sum of
the amounts so determined is less than or exceeds the total  contribution  to be
made to such trust in  accordance  with such funding  policy as applied to AT&T,
the AT&T  Entities,  Lucent and the Lucent  Entities as a group,  then  Lucent's
share of such  contribution  shall be  determined by increasing or reducing both
such amounts, as applicable, proportionately so as to eliminate such difference.

                  (d)  PARTICIPANT  CONTRIBUTIONS;   SETTLEMENTS,  REFUNDS,  AND
SIMILAR  PAYMENTS.  Until  such  time as a cash  benefit  payment  procedure  is
implemented pursuant to which the participant  contributions made under any AT&T
Health and Welfare Plan made by Lucent Individuals,  Transferred Individuals and
other  employees  and former  employees  of Lucent and the Lucent  Entities  and
beneficiaries and dependents thereof can be specifically identified as such, for
purposes of determining the Lucent  Liabilities  associated with such Plan, such
individuals  shall be deemed to have made such  contributions  in an amount that
bears the same  relationship to the total  contributions  by all participants to
such Plan as the number of such  individuals  who are  participants in such Plan
bears to the  total  number of  participants  in such  Plan.  If AT&T or an AT&T
Entity  receives  any amount that  represents  an offset to or  reduction of any
Liability relating to, arising out of or resulting from any AT&T Plan (including
any amount received in settlement of a dispute  regarding the amount of benefits
payable  under  such  Plan and any  refund of  premiums  paid to an  insurer  of
benefits  under  such Plan)  with  respect  to a period  before the Close of the
Distribution Date, then except to the extent Section  5.21(c)(iv) is applicable,
AT&T  shall  pay to  Lucent  a  portion  of such  amount  that  bears  the  same
relationship  to the total of such  amount as the number of Lucent  Individuals,
Transferred  Individuals and other employees and former  employees of Lucent and
the Lucent  Entities  who were  participants  in such Plan  during the period to
which such amount  relates  bears to the total  number of  participants  in such
Plan.

                  (e) ADMINISTRATIVE  EXPENSES NOT CHARGEABLE TO A TRUST. To the
extent not charged for pursuant to Section 8.1 or another Ancillary Agreement or
the ASA Agreement and to the extent not  chargeable  to a trust  established  in
connection with an AT&T Plan, Lucent shall be responsible, through either direct
payment from its own cash or  reimbursement  of AT&T from its own cash,  for the
following  expenses in the  administration  of the AT&T Plans while  Lucent or a
Lucent Entity is a Participating  Company in such Plans (and except as expressly
provided  below,  Lucent's  allocable  share  of  the  following  administrative
expenses  shall be that portion of the total such  expenses  that bears the same
relationship  to such  total  expenses  as the  number  of  Lucent  Individuals,
Transferred  Individuals and other employees and former  employees of Lucent and
the Lucent  Entities who are  participants in the applicable Plan bears to total
number of participants in




<PAGE>

such Plan):  (i) the costs  incurred in the  administration  of the AT&T Pension
Plans and other Plans providing benefits to retired  individuals,  including the
cost of managing any trust assets and performing  actuarial  calculations (which
shall be shared equally between Lucent and AT&T); (ii) the  recordkeeping  costs
(including  expenses  in  development  and  operation  of  the  daily  valuation
recordkeeping  system  for the AT&T  LTSSP)  and  other  costs  incurred  in the
administration  of the  AT&T  Savings  Plans  (including  expenses  in  employee
communications  materials  for the AT&T Savings Plans and  consultant  and other
out-of-pocket   fees  and   expenses   generally   related   to  the  design  or
administration  of the AT&T  Savings  Plans);  (iii)  the fees  paid to  benefit
delivery vendors under AT&T Health and Welfare Plans; (iv) COBRA  administrative
costs (of which Lucent's allocable share shall be that portion of the total such
costs that  bears the same  relationship  to such  total  costs as the number of
Lucent  Individuals,  Transferred  Individuals  and other  employees  and former
employees of Lucent and the Lucent  Entities and  beneficiaries  and  dependents
thereof who are  participants  in the  applicable  Plan bears to total number of
participants  in such Plan);  (v) the cost of  administrative  services  for the
Family Care Development Fund and other Work and Family programs;  (vi) the costs
incurred in the administration of the AT&T Executive  Benefits Plans,  including
payments  made to insurance  agents and brokers  (such as the agents and brokers
who administer  corporate-owned  life insurance and  trust-owned  life insurance
programs),  and payments made to vendors  (such as the vendor(s) who  administer
the AT&T Senior Management  Financial  Counseling  Program);  (vii) the expenses
incurred in  establishing  the AT&T Stock  Purchase  Plan and its  recordkeeping
system;  (viii)  the  consultant  and  other  out-of-pocket  fees  and  expenses
(including accounting,  actuarial, consulting, and legal fees, and photocopying,
printing,   and   similar   expenses)   generally   related  to  the  design  or
administration  of the AT&T Plans (which shall be shared equally  between Lucent
and AT&T); (ix) the payments for  administration of the AT&T Rabbi Trust and for
actuarial and legal work in connection with the AT&T Rabbi Trust (which shall be
shared equally between Lucent and AT&T); and (x) the payments for the management
of the assets of the AT&T Rabbi Trust  (which shall be prorated  between  Lucent
and AT&T based on relative value of Lucent's and AT&T's share of the liabilities
funded by AT&T Rabbi Trust assets with respect to AT&T and Lucent  Executives as
reflected in the IPO Registration Statement).

                  (f)  STOCK  AWARD  CHARGEBACKS.  Lucent  shall  pay  AT&T  the
following  amounts:  (i) with respect to each AT&T Option that is exercised by a
Lucent  Individual or another  employee of Lucent or a Lucent Entity at any time
after the Closing  Date,  the Spread on such  Option;  (ii) with respect to each
purchase of AT&T Common  Stock  pursuant  to the AT&T Stock  Purchase  Plan by a
Lucent  Individual or another  employee of Lucent or a Lucent Entity at any time
after the Closing  Date,  the Spread with respect to such  purchase;  (iii) with
respect to the vesting or delivery at any time after the Closing  Date of shares
of AT&T Common Stock  pursuant to an Award (other than an AT&T Option) held by a
Lucent Individual or another employee of Lucent or a Lucent Entity, the Value of
such AT&T Common Stock on the date of such vesting or delivery.  AT&T shall bill
Lucent  for such  amounts  from  time to time  (but  only  after  the  exercise,
purchase, vesting or delivery that gives rise to the obligation to make any such
payment),  and Lucent  shall pay such  amounts  promptly  after  receipt of such
bills.  The "Spread" on an Option or with respect to a purchase  pursuant to the
AT&T Stock Purchase Plan means the excess, if any, of the Value of the purchased
shares on the date of exercise of such Option or the date of such  purchase,  as
applicable,  over the price paid for such shares. The "Value" of a share of AT&T
Common Stock on a given date means the average of the high and the low per-share
prices of the AT&T Common Stock as listed on the NYSE on such date,  or if there
is no trading  on the NYSE on such date,  on the most  recent  previous  date on
which such trading takes place.

         8.3 1984 AT&T UNFUNDED DIVESTITURE  REIMBURSEMENT  AGREEMENTS. In order
to permit  AT&T to continue to honor any  obligations  it may have for  on-going
reimbursement  costs  payable  periodically  to the seven  Regional Bell Holding
Companies  and  Bell  Communications  Research,  Inc.  in  accordance  with  the
provisions of the Unfunded Cost Sharing Agreements,  Lucent shall provide, on an
annual basis and in accordance with the schedule  provided to Lucent by AT&T, at
no cost to AT&T, any  information  in its possession  required to enable AT&T to
determine,  validate,  and  reconcile the AT&T offset  amounts  specified in the
Unfunded  Cost  Sharing   Agreements.   Lucent  shall  also  provide  AT&T  with
information in its possession to the extent  requested by a party to an Unfunded
Cost Sharing  Agreement  pursuant to its rights  thereunder to audit information
provided  by Lucent to AT&T.  If Lucent or any Lucent  Entity  grants an "ad hoc
pension increase" as defined in either of the Unfunded Cost Sharing  Agreements,
as a result of which AT&T or any AT&T  Entity is  required  to pay  pursuant  to
either or both of the Unfunded Cost Sharing  Agreements any amounts in excess of
the  amounts  it would have been  required  to pay  absent  such ad hoc  pension
increase, then Lucent shall reimburse AT&T for the amount of such excess, as and
when it is paid by AT&T or such AT&T Entity.  The parties agree that any such ad
hoc increase  made by Lucent or any Lucent Entity to the extent not in excess of
a prior ad hoc  increase  by AT&T or any AT&T  Entity made after the date hereof
will not give rise to any  reimbursement  obligation  pursuant to the  foregoing
sentence,  but an ad hoc increase  made by Lucent or any Lucent  Entity prior to
any ad hoc  increase  made by AT&T or any AT&T  Entity  will  give  rise to such
reimbursement obligation (with no reduction in such reimbursement obligation due
to the  subsequent  ad hoc  increase  by AT&T or any  AT&T  Entity).  Except  as
specifically provided in the preceding two sentences, the foregoing shall not be
deemed to give rise to any  liability of Lucent under the Unfunded  Cost Sharing
Agreements.



         8.4 SHARING OF  PARTICIPANT  INFORMATION.  AT&T and Lucent shall share,
AT&T shall cause each  applicable  AT&T Entity to share,  and Lucent shall cause
each  applicable  Lucent Entity to share,  with each other and their  respective
agents and vendors  (without  obtaining  releases) all  participant  information
necessary  for the  efficient  and accurate  administration  of each of the AT&T
Plans and the Lucent Plans during the respective  Transition  Periods applicable
to such Plans, and with respect to each of the AT&T Health and Welfare Plans and
Lucent Health and Welfare Plans,  any additional  periods during which such Plan
is  subject  to the  restrictions  of  Section  5.8.  AT&T and  Lucent and their
respective   authorized   agents   shall,   subject   to   applicable   laws  on
confidentiality,  be given  reasonable and timely access to, and may make copies
of, all information relating to the subjects of this Agreement in the custody of
the other party,  to the extent  necessary  for such  administration.  Until the
Close of the Distribution Date, all participant information shall be provided in
the manner and medium  applicable to  Participating  Companies in the AT&T Plans
generally,  and thereafter until December 31, 1998, all participant  information
shall be  provided  in a manner  and  medium  that is  compatible  with the data
processing  systems of AT&T as in effect of the Close of the Distribution  Date,
unless otherwise agreed to by AT&T and Lucent.

         8.5 REPORTING AND DISCLOSURE AND COMMUNICATIONS TO PARTICIPANTS.  While
Lucent is a  Participating  Company in the AT&T Plans,  Lucent  shall take,  and
shall cause each other applicable  Lucent Entity to take, all actions  necessary
or  appropriate  to  facilitate  the  distribution  of  all  AT&T   Plan-related
communications  and  materials to  employees,  participants  and  beneficiaries,
including   summary  plan   descriptions  and  related   summaries  of  material
modification,  summary annual  reports,  investment  information,  prospectuses,
notices and enrollment  material for the Lucent Plans. Lucent shall pay AT&T the
cost relating to the copies of all such documents provided to Lucent,  except to
the extent  such costs are  charged  pursuant  to Section  8.1 or pursuant to an
Ancillary Agreement or the ASA Agreement.  Lucent shall assist, and Lucent shall
cause each other applicable Lucent Entity to assist,  AT&T in complying with all
reporting and disclosure  requirements  of ERISA,  including the  preparation of
Form 5500 annual reports for the AT&T Plans, where applicable.





<PAGE>

         8.6  NON-TERMINATION OF EMPLOYMENT;  NO THIRD-PARTY  BENEFICIARIES.  No
provision of this Agreement or the Separation and  Distribution  Agreement shall
be construed to create any right, or accelerate entitlement, to any compensation
or  benefit  whatsoever  on the  part  of  any  Lucent  Individual,  Transferred
Individual or other future,  present or former employee of AT&T, an AT&T Entity,
Lucent,  or a Lucent  Entity  under any AT&T Plan or Lucent  Plan or  otherwise.
Without  limiting the generality of the foregoing:  (i) neither the Distribution
nor the  termination of the  Participating  Company status of Lucent or a Lucent
Entity shall cause any employee to be deemed to have incurred a  termination  of
employment  which entitles such individual to the commencement of benefits under
any of  the  AT&T  Plans,  any of the  Lucent  Plans,  or any of the  Individual
Agreements; and (ii) except as expressly provided in this Agreement,  nothing in
this  Agreement  shall  preclude  Lucent,  at any time  after  the  Close of the
Distribution Date, from amending, merging, modifying, terminating,  eliminating,
reducing,  or  otherwise  altering in any respect any Lucent  Plan,  any benefit
under any Plan or any trust,  insurance policy or funding vehicle related to any
Lucent Plan.

         8.7 PLAN AUDITS.

                  (a) AUDIT RIGHTS WITH RESPECT TO THE ALLOCATION OR TRANSFER OF
PLAN ASSETS.  The allocation of Pension Plan assets and liabilities  pursuant to
Section 3.2, the transfer of assets from AT&T VEBAs pursuant to Sections 5.3 and
5.5,  the  transfer of RFA assets  pursuant  to Section 5.4 and the  transfer of
assets  from the AT&T Rabbi  Trust  pursuant  to Section 6.8 shall be audited on
behalf of both AT&T and Lucent by the  consulting  firm of Milliman & Robertson.
The scope of such audit  shall be limited  to the  accuracy  of the data and the
accuracy of the computation  and adherence to the methodology  specified in this
Agreement and except as set forth in the last  sentence of this Section  8.7(a),
such audit  shall not be  binding on the  parties.  Milliman &  Robertson  shall
provide  its report to both AT&T and Lucent.  No other audit shall be  conducted
with respect to the  transfer or  allocation  of Plan assets.  The costs of such
audit  shall  be  shared  equally  by AT&T and  Lucent,  or,  at each  company's
discretion and to the extent  allocable  thereto,  by their  respective  Pension
Plans.  To the  extent  such  audit  recommends  a change to the value of assets
allocated to a Lucent Plan of less than 0.25%, the original  determination shall
be binding on the  parties  and shall not be subject to the  dispute  resolution
process provided under the Separation and Distribution  Agreement. To the extent
such audit  recommends  such a change of 0.25% or more, any  unresolved  dispute
between the parties as to whether and how to make any change in response to such
recommendation shall be subject to the dispute resolution process provided under
the Separation and Distribution Agreement.

                  (b) AUDIT RIGHTS WITH RESPECT TO INFORMATION
PROVIDED.

                           (i) Each of AT&T and Lucent, and their
duly
authorized representatives,  shall have the right to conduct audits with respect
to all information  provided to it by the other party.  The party conducting the
audit (the  "Auditing  Party")  shall have the sole  discretion to determine the
procedures  and  guidelines  for  conducting  audits and the  selection of audit
representatives under this Section 8.7(b); provided, that audits with respect to
the allocation or transfer of Plan assets and liabilities  shall be subject only
to Section 8.7(a). The Auditing Party shall have the right to make copies of any
records at its expense,  subject to the confidentiality  provisions set forth in
the Separation and Distribution  Agreement,  which are incorporated by reference
herein.   The  party  being   audited   shall   provide  the  Auditing   Party's
representatives  with  reasonable  access  during normal  business  hours to its
operations, computer systems and paper and electronic files, and


                                      -50-

<PAGE>

provide  workspace to its  representatives.  After any audit is  completed,  the
party being audited shall have the right to review a draft of the audit findings
and to comment on those  findings  in writing  within five  business  days after
receiving such draft.

                           (ii) The Auditing Party's audit rights
under this
Section  8.7(b) shall  include the right to audit,  or  participate  in an audit
facilitated by the party being audited,  of any  Subsidiaries  and Affiliates of
the party being audited and of any benefit providers and third parties with whom
the party being  audited  has a  relationship,  or agents of such party,  to the
extent  any  such  persons  are  affected  by or  addressed  in  this  Agreement
(collectively,  the "Non-parties").  The party being audited shall, upon written
request from the Auditing Party,  provide an individual (at the Auditing Party's
expense) to  supervise  any audit of a Non-party.  The  Auditing  Party shall be
responsible for supplying, at the Auditing Party's expense, additional personnel
sufficient  to  complete  the  audit  in  a  reasonably   timely   manner.   The
responsibility of the party being audited shall be limited to providing,  at the
Auditing Party's expense,  a single individual at each audited site for purposes
of facilitating the audit.

                  (c) AUDITS REGARDING VENDOR CONTRACTS.  From Immediately after
the Distribution  Date through December 31, 1998, AT&T and Lucent and their duly
authorized  representatives  shall have the right to conduct  joint  audits with
respect to any vendor  contracts that relate to both the AT&T Health and Welfare
Plans and the Lucent  Health and Welfare  Plans.  The scope of such audits shall
encompass  the  review of all  correspondence,  account  records,  claim  forms,
canceled drafts (unless retained by the bank),  provider bills,  medical records
submitted with claims,  billing  corrections,  vendor's internal  corrections of
previous errors and any other documents or instruments  relating to the services
performed by the vendor under the applicable vendor  contracts.  AT&T and Lucent
shall agree on the performance standards, audit methodology, auditing policy and
quality measures and reporting  requirements relating to the audits described in
this Section 8.7 and the manner in which costs incurred in connection  with such
audits will be shared.

         8.8  BENEFICIARY  DESIGNATIONS.  All beneficiary  designations  made by
Transferred  Individuals  for AT&T Plans shall be  transferred to and be in full
force and effect under the  corresponding  Lucent  Plans until such  beneficiary
designations are replaced or revoked by the Transferred  Individual who made the
beneficiary designation.

         8.9  REQUESTS FOR IRS RULINGS AND DOL OPINIONS.

                  (a) COOPERATION. Lucent shall cooperate fully with AT&T on any
issue relating to the transactions contemplated by this Agreement for which AT&T
elects to seek a  determination  letter or private letter ruling from the IRS or
an advisory  opinion from the DOL. AT&T shall  cooperate  fully with Lucent with
respect to any request for a determination  letter or private letter ruling from
the IRS or advisory opinion from the DOL with respect to any of the Lucent Plans
relating to the transactions contemplated by this Agreement.

                  (b) APPLICATIONS. AT&T and Lucent shall make such applications
to regulatory agencies, including the IRS and DOL, as may be necessary to ensure
that any  transfers of assets from the AT&T Health  Trusts to the Lucent  Health
Trusts and from the AT&T LTD VEBA to the Lucent LTD VEBA will neither (i) result
in any adverse tax, legal or fiduciary consequences to AT&T and Lucent, the AT&T
Health Trusts and the AT&T LTD VEBA, the Lucent Health Trusts and the Lucent LTD
VEBA, any participant  therein or beneficiaries  thereof,  or any of AT&T Health
Trusts and the AT&T LTD



<PAGE>

VEBA, any successor welfare benefit funds established by or on behalf of Lucent,
or the trustees of such trusts,  nor (ii) contravene any statute,  regulation or
technical pronouncement issued by any regulatory agency. Before the Close of the
Distribution  Date,  Lucent shall prepare all forms required to obtain favorable
tax-exempt  determination  letters from the IRS for the Lucent Health Trusts and
the Lucent LTD VEBA, and, if applicable, the Lucent Union VEBA.
Lucent and AT&T
agree to  cooperate  with each other to fulfill  any  filing  and/or  regulatory
reporting obligations with respect to such transfers.

                  (c) LIFE  INSURANCE.  To the extent the transfer or allocation
of all or a portion of any life insurance policies results in any adverse tax or
legal consequences,  including (i) any finding that such transfer results in the
creation of a modified  endowment  contract  within the meaning of Code  Section
7702A, a transfer for value within the meaning of Code Section 101(a), or a lack
of insurable  interest for either AT&T or Lucent (or their respective trusts, if
any), or (ii) multiple claims for insurance proceeds, AT&T and Lucent shall take
such steps as may be necessary to contest any such finding and, to the extent of
any final determination that such adverse tax or legal consequences will result,
AT&T and Lucent shall make such further  adjustments so as to place both parties
in the  proportionate  financial  position  that  they each  would  have been in
relative to the other but for such adverse tax or legal consequences.

         8.10  FIDUCIARY MATTERS.

                  (a) FIDUCIARY  STATUS.  AT&T and Lucent each acknowledges that
actions  required  to be taken  pursuant  to this  Agreement  may be  subject to
fiduciary  duties or standards of conduct under ERISA or other  applicable  law,
and no party shall be deemed to be in violation of this Agreement if it fails to
comply with any provisions hereof based upon its good faith  determination  that
to do so would violate such a fiduciary duty or standard.

                  (b)  INDEPENDENT  FIDUCIARY.  Lucent  shall retain a fiduciary
independent  of AT&T to review and  approve the types and value of the assets to
be  transferred to the Lucent Plans from the AT&T Plans as described in Articles
III and IV of this Agreement to the extent that such Plans are subject to Part 4
of Title I of ERISA.  The foregoing  shall not prevent  Lucent from engaging any
fiduciaries for any other purposes.

         8.11 AGREEMENT WITH ACTUARIAL  SCIENCES  ASSOCIATES,  INC. Lucent shall
enter into an agreement with Actuarial Sciences  Associates,  Inc. ("ASA"), in a
form  substantially  similar to Exhibit A. Within 60 days after the Distribution
Date,  such agreement  shall be presented for  ratification by Lucent's Board of
Directors or its authorized delegate.

         8.12  COLLECTIVE  BARGAINING.  To the  extent  any  provision  of  this
Agreement is contrary to the provisions of the Collective  Bargaining  Agreement
or any other collective  bargaining  agreement to which AT&T or any Affiliate of
AT&T is a  party,  the  terms  of such  collective  bargaining  agreement  shall
prevail.  Should any provisions of this Agreement be deemed to relate to a topic
determined by an appropriate  authority to be a mandatory  subject of collective

                                 QUALIFIED PLANS

         3.1 NCR PENSION PLANS.

             (a) NAMED  FIDUCIARY FOR NCR PENSION PLANS.  NCR hereby  represents
and  warrants  to  AT&T  that  (i) the  NCR  Pension  Plans  as  defined  herein
constitute,  as of the date hereof,  all of the defined  benefit  pension  plans
sponsored by NCR and the Persons that are, as of the date hereof, NCR Controlled
Persons, all other such plans having been merged into the NCR Pension Plan on or
before November 15, 1996, (ii) each NCR Pension Plan has been amended to provide
that NCR is the named  fiduciary of such NCR Pension Plan,  and that AT&T is not
the named  fiduciary  of such NCR  Pension  Plan,  in each case for  purposes of
negotiating  the terms and conditions of this Section 3.1 and entering into this
Agreement,  and (iii) that it has  delivered to AT&T true,  correct and complete
copies  of such  amendments  and  the  resolutions  of its  Board  of  Directors
authorizing such amendments and providing for the delegation of the authority to
act in such fiduciary capacity by NCR to individual employees of NCR. As soon as
practicable  after  the  Close of the NCR  Distribution  Date,  and in any event
before the Second Transfer, NCR shall seek to have its Board of Directors ratify
such amendments and resolutions.

             (b)  PRE-DISTRIBUTION  ACTIONS BY NCR.  NCR shall
take all  actions
necessary or appropriate so that before the Close of the NCR
Distribution  Date:
(i) one or more  individuals or entities are appointed in place of AT&T as named
fiduciary under the NCR Pension Plans;  (ii) appropriate  trustees,  custodians,
investment  managers and other fiduciaries with respect to the NCR Pension Plans
have been appointed, so as to permit the LTIT





<PAGE>

Redemption  and the MPT  Withdrawal to occur  promptly in  accordance  with this
Section 3.1; (iii) NCR shall have entered into an Investment  Advisory Agreement
with ATTIMCO providing for the management of the assets of the NCR Pension Plans
by ATTIMCO during the period from Immediately  after the NCR  Distribution  Date
until the completion of the LTIT Redemption and the MPT Withdrawal in accordance
with this  Section  3.1;  and (iv) NCR shall  have taken all such  actions  with
respect  to the  assets  identified  on  Schedule  V  hereto  as  ATTIMCO  shall
reasonably require.

             (c) TRANSFER OF ASSETS OF NCR PENSION PLANS FROM LTIT
AND MPT.

                 (i) LTIT  REDEMPTION  AND MPT  WITHDRAWAL.  AT&T shall take all
actions necessary or appropriate to accomplish the LTIT Redemption, and AT&T and
NCR  shall  take all  steps  necessary  or  appropriate  to  accomplish  the MPT
Withdrawal,  in each case in accordance  with this Section 3.1(c) as promptly as
practicable  after the later of (A) the Close of the NCR  Distribution  Date and
(B) the  completion  of the  ratification  referred  to in the last  sentence of
Section 3.1(a) and all actions required to be taken pursuant to Section 3.1(b).

                 (ii) VALUATION OF LTIT ASSETS; LTIT REDEMPTION. Under the terms
of the LTIT Agreement, the Total Asset Value and Net Asset Value (as those terms
are defined in the LTIT  Agreement) of the assets of the LTIT will be determined
by ATTIMCO,  in its capacity as named  fiduciary of the LTIT, as of December 31,
1996. As part of such  determination  process,  ATTIMCO shall also determine the
portion of such Net Asset Value that  represents the share  allocable to the NCR
Pension Plans in the LTIT through their interests in the MPT (the "NCR Allocable
Share") in accordance with the terms of the LTIT Agreement.  Such determinations
shall be audited by Coopers & Lybrand in  accordance  with the normal  valuation
procedures for the LTIT. AT&T, in its capacity as Authorized  Fiduciary  (within
the meaning of the LTIT  Agreement) for the MPT, shall then direct  ATTIMCO,  in
its capacity as named fiduciary of the LTIT, to redeem,  pursuant to Section 7.2
of the LTIT  Agreement,  a portion of the MPT's allocable share of the assets of
the LTIT having a value,  as of  December  31,  1996,  at least equal to the NCR
Allocable Share (the "LTIT  Redemption").  Such assets shall consist of a mix of
assets  satisfying the  requirements of Schedule VI hereto (as such Schedule may
be amended  hereafter by written  agreement  between AT&T and NCR). AT&T and NCR
acknowledge that the LTIT Redemption may be subject, in whole or in part, to the
consent of Lucent,  in its capacity as Authorized  Fiduciary (within the meaning
of the  LTIT) of  certain  plans  participating  in the  LTIT,  and agree to use
reasonable  best  efforts to obtain any such  required  consent,  but failure to
obtain such consent shall not be considered a violation hereof.

                 (iii)  WITHDRAWAL  FROM  MPT.  AT&T (in its  capacity  as named
fiduciary of the MPT) shall cause the assets received by the MPT pursuant to the
LTIT  Redemption to be segregated  upon such receipt in  anticipation of the MPT
Withdrawal.  Such assets, together with the proceeds of any sale of such assets,
any other assets in which such proceeds may be  reinvested,  and any  dividends,
interest, distributions and other income realized from such assets, proceeds and
other assets, in each case during the period from their receipt by the MPT until
they are  transferred  to the trustee(s) of the NCR Pension Plans as hereinafter
provided,  are referred to collectively as the "Segregated Assets." AT&T and NCR
shall then direct the  withdrawal of the NCR Pension Plans from the MPT pursuant
to Section 5(c) of MPT Agreement (the "MPT Withdrawal") in exchange for all or a
portion of the Segregated Assets, as set forth below. The transfer of Segregated
Assets from the trustee of the MPT to the  trustee(s)  of the NCR Pension  Plans
pursuant to the MPT  Withdrawal  shall  occur in two steps.  The first step (the
"First Transfer") shall be a





<PAGE>

transfer  of a portion of the  Segregated  Assets  selected  by ATTIMCO  (in its
capacity as a fiduciary of the MPT) that it  determines  to have a value,  as of
December 31, 1996, equal to approximately 90 percent of the NCR Allocable Share.
The  second  step (the  "Second  Transfer")  shall be a transfer  of  additional
Segregated  Assets  selected by ATTIMCO (in its  capacity as a fiduciary  of the
MPT), such that the Segregated  Assets  transferred to the trustee(s) of the NCR
Pension Plans in the First Transfer and the Second Transfer (I) have a value, as
of December 31, 1996,  equal to the NCR Allocable  Share,  and (II) constitute a
mix of assets  satisfying the requirements of Schedule VI hereto.  No adjustment
shall be made to the assets so  transferred as a result of any  diminishment  in
the value of the Segregated Assets after December 31, 1996.

                 (iv) ACCEPTANCE OF ASSET TRANSFER.  The completion of the First
Transfer and the Second Transfer shall be subject in each case to the receipt by
ATTIMCO, from NCR and each of the recipient trustee(s) of the NCR Pension Plans,
of a Receipt and Release  substantially in the forms attached hereto as Exhibits
A and B, respectively  (with such modifications as may be agreed to by ATTIMCO).
NCR hereby  agrees to give  Receipts  and Releases  substantially  in such forms
unless it determines in good faith that either (I) AT&T or ATTIMCO has failed to
comply with the  requirements  of this Section  3.1(c) or (II) it is required by
ERISA to withhold such Receipts and Releases.

             (d) RELEASE AND ASSUMPTION OF LIABILITIES.

                 (i) RELEASES.  Effective Immediately after the NCR Distribution

                 (iii)  RESTRICTED  STOCK AND RESTRICTED  STOCK UNITS. NCR shall
cause each Award that  consists of non-vested  restricted  shares of AT&T Common
Stock or restricted  stock units relating to shares of AT&T Common Stock that is
outstanding and held by an NCR Employee as of the Close of the NCR  Distribution
Date, other than the Awards described in Schedule VII, to be replaced, effective
Immediately  after the NCR  Distribution  Date, with either a replacement  Award
described below or such other form of compensation not based on NCR Common Stock
as NCR  shall  determine.  Any  such  replacement  Award  shall  be a new  Award
consisting  of a number of  non-vested  restricted  shares of NCR  Common  Stock
and/or  restricted  stock units  relating to shares of NCR Common Stock equal to
the number of non-vested  restricted  shares or  restricted  stock units of AT&T
Common  Stock  constituting  such Award as of the Close of the NCR  Distribution
Date multiplied by the Ratio,  and then rounded down to the nearest whole share.
NCR shall pay to the holder of any such  replacement  Award, at the time of such
replacement,  cash in lieu of any fractional share based on the NCR Stock Value.
Each such  replacement  Award shall otherwise have the same terms and conditions
as were  applicable to the  corresponding  AT&T Award as of the Close of the NCR
Distribution  Date,  except that references to AT&T and its Affiliates  shall be
amended to refer to NCR and its Affiliates and dividend equivalent payments,  if
any,  with  respect to  dividends,  the  record  date for which is after the NCR
Distribution  Date shall be paid with  reference  to  dividends,  if any, on NCR
Common Stock.

                 (iv)  CHARGEBACK.  If,  at any time  after the Close of the NCR
Distribution  Date,  AT&T is required to deliver shares of AT&T Common Stock, or
shares of AT&T Common Stock vest, pursuant to an Award that NCR fails to replace
pursuant to this Section 4.3 or an Award  listed on Schedule  VII, NCR shall pay
AT&T the following amounts:  (A) with respect to each such Award that is an AT&T
Option,  the Spread on such Option;  (B) with respect to the vesting or delivery
of shares of AT&T Common  Stock  pursuant  to such an Award  (other than an AT&T
Option),  the Value of such AT&T  Common  Stock on the date of such  vesting  or
delivery and (C) with respect to each such Award,  the amount of any withholding
taxes  with  respect  thereto  which are not paid or  reimbursed  to AT&T by the
holder of such Award. In addition, NCR shall pay AT&T the amount of any payments
made by AT&T with respect to fractional shares under any Award that NCR fails to
replace  pursuant to this Section 4.3 or an Award listed on Schedule  VII.  AT&T
shall bill NCR for such amounts from time to time (but only after the  exercise,
purchase, vesting, delivery or payment that gives rise to the obligation to make
any such payment), and NCR shall pay such amounts promptly after receipt of such
bills.  The "Spread" on an Option means the excess,  if any, of the Value of the
purchased  shares on the date of exercise of such Option over the price paid for
such  shares.  The "Value" of a share of AT&T Common Stock on a given date means
the average of the high and the low per-share prices of the AT&T Common Stock as
listed on the NYSE on such  date,  or if there is no trading on the NYSE on such
date, on the most recent previous date on which such trading takes place.

             (c) NCR INDIVIDUALS  WHO ARE NOT NCR EMPLOYEES.  Each Award that is
outstanding  and held by an NCR Individual  other than an NCR Employee as of the
Close of the NCR Distribution  Date shall remain  outstanding  Immediately after
the NCR  Distribution  Date in accordance with its terms as applicable as of the
Close  of the NCR  Distribution  Date,  subject  to such  adjustments  as may be
applicable to outstanding Awards held by AT&T Individuals.

         4.4 AT&T  SPLIT  DOLLAR  LIFE  INSURANCE.  AT&T and NCR shall  take all
actions necessary or appropriate to assign to NCR,  effective  Immediately after
the NCR Distribution  Date, AT&T's rights and interests in the Split Dollar Life
Insurance policies under the Senior Management Individual Life Insurance Program
and the Senior  Management  Basic Life Insurance  Program issued by Metropolitan
Life Insurance Company,  Hartford Life Insurance Company, and Confederation Life
Insurance  Company (or their  successors in interest,  including  Pacific Mutual
Life Insurance Company),  and any additional split dollar life insurance program
that may be implemented by AT&T before the Close of the NCR  Distribution  Date,
with respect to NCR  Individuals  (such  policies,  the  "Assigned  Split Dollar
Policies").  Such actions  shall  include  NCR's  acceptance  of any  collateral
assignments,  policy endorsements or such other documentation  executed by or on
behalf  of  NCR  Individuals,  or  any  trustee  of  any  trust  to  which  such
individual's  policy rights or incidents of ownership  under the Assigned  Split
Dollar  Policies have been assigned,  and NCR's entering into such agreements as
may be necessary to fulfill any obligations of AT&T to any insurance  company or
insurance  agent or broker under the Assigned  Split Dollar  Policies.  From and
after the date of the assignment of any Assigned Split Dollar Policy to NCR, NCR
shall  assume  and be  solely  responsible  for all  Liabilities,  and  shall be
entitled  to all  benefits,  of AT&T  under  such  policy  and under the  Senior
Management Life Insurance  Program,  the Senior  Management Basic Life Insurance
Program and any  additional  split  dollar life  insurance  program  that may be
implemented by AT&T before the Close of the NCR  Distribution  Date, as the case
may be, with respect to such policies,  and any related  agreements entered into
by NCR Individuals.

         4.5 INDIVIDUAL AGREEMENTS.

             (a)  GENERAL.  Except  as  specifically  provided  in the  next two
sentences,  NCR  shall  assume  or  retain,  as the case may be,  and be  solely
responsible  for all  Liabilities  relating to, arising out of or resulting from
NCR Individual Agreements,  and AT&T shall assume or retain, as the case may be,
and be solely  responsible  for all  Liabilities  relating to, arising out of or
resulting from AT&T  Individual  Agreements.  AT&T shall retain the  Liabilities
under NCR Individual  Agreements  specified on Schedule VIII and shall reimburse
NCR for the amounts  described  on Schedule IX when and as such amounts are paid
by NCR. NCR shall reimburse AT&T for the amounts  described on Schedule X as set
forth  thereon.  For  purposes of this  Section  4.5,  Liabilities  relating to,
arising out of or resulting  from NCR Plans or AT&T Plans  without  reference to
any Individual  Agreement  shall not be considered to relate to, arise out of or
result from any  Individual  Agreement,  even if such  Liabilities  or Plans are
described in such Individual Agreements.

             (b) PHANTOM  SHARE  ACCOUNTS.  The phantom AT&T Shares  credited to
each of the phantom share accounts established pursuant to the agreements listed
on  Schedule  XI  shall  be  converted,  effective  Immediately  after  the  NCR
Distribution Date, to a number of phantom NCR Shares equal to the number of such
phantom  AT&T  Shares  reflected  in such  account  as of the  Close  of the NCR
Distribution  Date multiplied by the Ratio. If AT&T declares any dividend (other
than the dividend that effects the NCR Distribution),  the record date for which
is before the NCR Distribution  Date and the payment date for which is after the
NCR  Distribution  Date,  each such phantom share account shall be credited with
such dividend in accordance with the terms of the relevant  agreement  listed on
Schedule XI, except that such dividend  shall be converted into NCR Common Stock
rather than AT&T Common Stock. After the Close of the NCR Distribution Date, the
dividends  credited  to such  phantom  share  accounts  shall be  determined  by
reference to dividends on NCR Common Stock rather than AT&T Common Stock.

<PAGE>

York, as to all matters,  including matters of validity,  construction,  effect,
performance and remedies.

         7.9 TAX DEDUCTIONS.  It is the intention of AT&T and NCR that the party
that  actually  bears the cost  (whether  directly  or  indirectly)  of making a
payment  with  respect to, or (except as provided  below) whose stock is used to
satisfy, a Liability governed by this Agreement shall be entitled to any and all
tax benefits associated  therewith,  including the benefit of taking a deduction
with respect to such payment or satisfaction for income tax purposes,  and shall
be obligated to satisfy all tax withholding  obligations  with respect  thereto,
and AT&T and NCR  agree to take no  action  inconsistent  with  such  intention.
Notwithstanding  the foregoing,  AT&T and NCR recognize that it is possible that
the Internal  Revenue Service or another taxing  authority will take a different
position.  Therefore, AT&T and NCR agree that: (a) if either of them is notified
by the Internal Revenue Service or another taxing authority that it is taking or
proposes to take a different position,  the party receiving such notice shall so
notify the other;  (b) if,  when and to the extent that AT&T or a Person that is
then an AT&T  Controlled  Person receives a tax benefit as a result of a payment
made by NCR or a Person that is then an NCR  Controlled  Person with respect to,
or the  use of NCR  Common  Stock  to  satisfy,  a  Liability  governed  by this
Agreement,  AT&T shall pay to NCR, or shall cause such AT&T Controlled Person to
pay to NCR, an amount equal to the net tax benefit realized by AT&T or such AT&T
Controlled  Person, as and when realized;  and (c) if and to the extent that NCR
or a Person that is then an NCR  Controlled  Person  receives a tax benefit as a
result of a  payment  made by AT&T or a Person  that is then an AT&T  Controlled
Person with  respect to, or (except as provided  below) the use of AT&T stock to
satisfy, a Liability governed by this Agreement, NCR shall pay to AT&T, or shall
cause such NCR Controlled  Person to pay to AT&T, an amount equal to the net tax
benefit realized by NCR or such NCR Controlled Person, as and when realized. For
purposes of this  Section 7.9, NCR shall be entitled to any and all tax benefits
with  respect  to Awards as to which NCR  makes a payment  to AT&T  required  by
Section  4.3(b)(iv)  hereof,  and AT&T  shall  not be  entitled  to any such tax
benefits, notwithstanding the fact that its stock is used to satisfy, or it pays
cash to satisfy,  the Liabilities  with respect to such Awards;  provided,  that
AT&T shall be  obligated  in the first  instance to satisfy all tax  withholding
obligations  with respect  thereto,  subject to reimbursement by NCR pursuant to
Section  4.3(b)(iv)  hereof.  The net tax benefit to either party resulting from
payment or  satisfaction  of a Liability  shall be deemed to equal the excess of
(i) the taxes that would have been paid by such party if such party had not paid
or satisfied  such  Liability over (ii) the taxes that are actually paid by such
party.

         7.10  AGREEMENTS  WITH THIRD PARTIES.  The provisions of this Agreement
regarding the  allocation of  Liabilities  are intended only to provide for such
allocation  as between AT&T and NCR, and shall have no effect on any  agreements
with respect thereto among AT&T, any of its Affiliates  and/or one or more third
parties,  or  among  NCR  and any of its  Affiliates  and/or  one or more  third
parties,  including the Lucent EBA. To the extent that (i) any Liability assumed
or retained by NCR  hereunder,  (ii) any other  Liability  accrued under any NCR
Plan  not   specifically   assumed  by  AT&T  hereunder,   or  (iii)  any  other
employee-related  Liability  primarily  related to,  arising out of or resulting
from the operation of the NCR Business (as conducted at any time prior to, on or
after the NCR Distribution Date) not specifically assumed by AT&T hereunder,  is
subject to the sharing  arrangement  for  Contingent  Liabilities  under Section
6.3(b)(ii) of the Separation  and  Distribution  Agreement,  NCR shall be solely
responsible  for AT&T's share  thereof (as  determined  pursuant to said Section
6.3(b)(ii)),  but no provision of this  Agreement  shall be deemed to relieve or
release Lucent from responsibility for its share thereof (as determined pursuant
to said Section 6.3(b)(ii)).

                               NATURE OF AGREEMENT

                  1A.1 PURPOSE AND SCOPE OF THIS AGREEMENT.  The purpose of this
Agreement  is to permit  Supplier  to provide  and  Ordering  Company to receive
Supplier's  Products,  Licensed  Materials,  and Services.  This Agreement shall
govern all transactions  pursuant to which Supplier provides Products,  Licensed
Materials  and Services to AT&T and Ordering  Companies.  AT&T and Supplier will
develop a  template  no later than June 30,  1996 for use when AT&T or  Ordering
Company is ordering  Products,  Licensed  Materials  and Services  from Supplier
pursuant to this Agreement for use outside the United States. This template will
be used as the  starting  point for  Supplemental  Agreements  to  address  such
purchases and will address the additional  country and  customer-specific  terms
and requirements  with the particular  transaction.  This Agreement shall govern
Supplier's  sale and  licensing to Ordering  Companies of  Supplier's  Products,
Licensed Materials and Services for Ordering  Companies'  internal business uses
only,  and does not permit AT&T to resell or sublicense  any Products,  Licensed
Materials or Services provided hereunder as a distributor of same. However, this
Agreement,  including  any  restrictions  on use,  resale  and  transfer  is not
intended to prohibit  Ordering  Company from reselling or transferring  Products
and Licensed  Materials  no longer  needed for the  operation  of its  business,
provided,  that, in the case of Software,  such transfers are made in accordance
with the provisions of Article 9. All terms and conditions  governing  resale or
sublicensing  of  Supplier's  Products,  Licensed  Materials  and  Services as a
distributor shall be addressed in a separate agreement.


<PAGE>




This  Agreement  is  organized in the  following  manner:  Part 1 sets forth the
common  terms and  conditions  that  apply to all sales  and  licenses  executed
pursuant to this Agreement, unless otherwise stated in Part 2. Part 2 sets forth
the additional terms and conditions which govern Supplier's provision of network
infrastructure Products,  Licensed Materials and Services, other than such items
currently provided by Supplier's Business  Communications Systems business unit,
previously known as "GBCS," ("BCS").  Part 3 sets forth the additional terms and
conditions which govern Supplier's provision of Products, Licensed Materials and
Services provided by BCS.

                  1A.2 STATEMENT OF ASPIRATIONS. In an effort to ensure that the
parties remain fully focused upon their shared  objectives and aspirations,  the
parties  agree that the  following  principles  shall govern their work together
during the term of this Agreement:


                (a) Both parties want Lucent  Technologies  Inc.
to provide AT&T
with Products,  Licensed  Materials and Services that confer
significant  offer
differentiation,  premium value and operating  cost  reduction
consistent  with
AT&T's brand equity, and shall work together so that Lucent
Technologies Inc.
may assist AT&T in this manner;



                  (b) The parties recognize that Supplier's pricing of Products,
Licensed  Materials  and  Services  must balance two  fundamental  requirements:
AT&T's  requirement  for the  lowest  possible  operating  costs and  Supplier's
requirement for adequate return on and recovery of investment;

                  (c) The  parties  shall  at all  times  take  care to  conduct
themselves with the highest integrity, to respect all individuals, and to obtain
the maximum benefits of a shared end user customer focus, effective teamwork and
the parties' innovativeness; and

                  (d) The  parties  desire to  maintain a
relationship  that is
warm, open and mutually profitable.

                  1A.3 VOLUME  COMMITMENT.  (a) AT&T commits that the  aggregate
amount paid by Ordering  Companies  (including  AT&T Wireless  Services Inc.) to
Supplier during the calendar years 1996,  1997, and 1998 for Products,  Licensed
Materials, and Services, pursuant to this Agreement, any Supplemental Agreement,
any other agreement or otherwise,  between an Ordering  Company and Supplier for
Supplier's provision of Products,  Licensed Materials or Services to an Ordering
Company,  will total at least three billion  dollars  ($3,000,000,000).  If that
commitment is not  fulfilled by December 31, 1998,  Supplier  shall,  in January
1999,  bill AT&T a carrying  charge equal to the shortfall at December 31, 1998,
multiplied  by the Prime Rate (as  defined in the  Separation  and  Distribution
Agreement) plus two percent (2%).  Thereafter,  Supplier shall, each month, bill
AT&T a  carrying  charge  equal  to the  shortfall,  if  any,  at the end of the
preceding  month,  multiplied  by 1/12  multiplied  by the  Prime  Rate plus two
percent  (2%).  Such  billing  shall  continue  until the three  billion  dollar
($3,000,000,000) commitment is fulfilled. AT&T will pay these bills as set forth
in Section 3.2, INVOICES AND TERMS OF PAYMENT.  The remedy in this Section 1A.3,
VOLUME COMMITMENT, is


<PAGE>



Supplier's  exclusive  remedy for AT&T's  failure to fulfill  the three  billion
dollar ($3,000,000,000) volume commitment.

                  (b) AT&T expects, but does not commit, that Products, Licensed
Materials  and  Services  in the amount of one  billion  three  hundred  million
dollars  ($1,300,000,000),  out of the three  billion  dollar($3,000,000)  total
volume commitment, will be ordered in 1996. Therefore, the shortfall billing and
payment  arrangement  set  forth in  subparagraph  (a)  above  does not apply to
failure to meet this expectation by the end of 1996.

                  (c) Prior to the Closing  Date (as  defined in the  Separation
and Distribution  Agreement),  AT&T shall deliver to Supplier as advance payment
for purchases of Products,  Services,  Software, or Licensed Materials an amount
equal to five hundred million dollars  ($500,000,000).  Commencing on January 1,
1997,  Supplier  shall  apply a portion of such  amount as a credit  against any
undisputed  invoiced  amounts due and payable to Supplier  from AT&T or, if AT&T
shall so  specify  at any time,  from any other  Ordering  Company,  on or after
January 1, 1997, in full  satisfaction  of all  obligations  of AT&T or any such
Ordering Company then due in connection therewith. Supplier shall continue to so
apply such advance  payment as a credit against such  undisputed  invoices until
fully applied.

                 1A.4 GOVERNING  TERMS.  (a) Current Order  Performance:  On the
Effective Date of this Agreement, Supplier shall be in the process of performing
several  Ordering  Company  orders,  some of which have not been the  subject of
written Orders and purchase agreements. In addition, Supplier shall be following
many existing engineering, installation and maintenance practices and procedures
that have been developed  mutually by Supplier and Ordering Company but have not
been completely  documented.  The parties intend that Supplier shall continue to
provide the same  Products,  Services and Licensed  Materials  which Supplier is
providing or has agreed to provide each Ordering Company  (hereinafter  "Pending
Orders") subject to the availability of third party components and provided that
Ordering  Company  shall  retroactively  compensate  Supplier for any  Products,
Licensed Materials and Services provided by Supplier without compensation at the
prices  and  rates  set  forth  in any  mutual  agreements  entered  into.  Such
retroactive  compensation  shall begin no earlier  than the  Effective  Date and
shall be capped at twenty  million  dollars  ($20,000,000)  per month.  Supplier
shall not be liable  for any  injury  to  Ordering  Company  that  results  from
Supplier's  employees  and/or  contractors  failure to be aware of practices and
procedures  that had not, at the time of  Supplier's  actions,  been  reduced to
writing. Supplier and Ordering Company recognize that the existing practices and
procedures  will need to be reevaluated in light of the  restructure of AT&T. As
part of this reevaluation,



<PAGE>





Supplier  and Ordering  Company may decide to continue  existing  practices  and
procedures  or one  party  may  notify  the  other  that it  wishes to change or
eliminate certain practices or procedures.


The  parties  agree to use their best  efforts to identify  any other  Products,
Licensed  Materials and Services  provided by Supplier to Ordering  Company that
require  commercialization and to formalize such undocumented  arrangements in a
commercially  reasonable manner that is consistent with the terms and conditions
contained herein no later than March 31, 1996. The parties acknowledge that such
formalization  and  modification of those  arrangements may result in changes in
the terms  and  conditions  pursuant  to which  such  items  are  provided.  All
agreements  will be reduced to writing  which will govern  transactions  between
Supplier and all Ordering Companies,  unless otherwise agreed to. If the parties
are unable to  negotiate  a  satisfactory  resolution,  the  dispute  resolution
provisions of Article 5A herein shall apply. Services not currently performed by
Supplier are not covered under this Section 1A.4,  GOVERNING  TERMS, and will be
covered under separate Supplemental Agreements.

With respect to Pending  Orders,  this Agreement is  incorporated  by reference,
however,  in the event of  conflict  between  the terms and  conditions  of this
Agreement  and the  terms  and  conditions  of  Pending  Orders,  the  terms and
conditions of Pending Orders shall prevail over the terms and conditions of this
Agreement until such time that the Pending Orders are formalized,  terminated or
expired.

                  (b) Future  Procurements:  All future Orders and  Supplemental
Agreements pursuant to which Supplier provides Products,  Licensed Materials and
Services to AT&T Company  shall be deemed to  incorporate  and be subject to the
terms and conditions of this Agreement,  regardless of whether any such Order or
Supplemental  Agreement  expressly  incorporates  this  Agreement by  reference,
unless such Order or Supplemental  Agreement  expressly  provides that it is not
subject to this  Agreement.  To the extent that any exhibit to this Agreement or
any document other than a Supplemental Agreement conflicts with the body of this
Agreement,  the body of this Agreement  shall prevail over such exhibit or other
document.  To the  extent  that a  Supplemental  Agreement  conflicts  with this
General Purchase  Agreement,  the Supplemental  Agreement shall prevail over the
body of this Agreement.  To the extent that the  Supplemental  General  Purchase
Agreement,  No.  LC3757D,  conflicts with either or both of this Agreement and a
Supplemental  Agreement,  the  Supplemental  General  Purchase  Agreement  shall
prevail over those other agreements.

                 1A.5 TERM OF AGREEMENT.  This Agreement shall become  effective
on the  Effective  Date and shall  continue  in effect  for a period of five (5)
years. The term of this Agreement shall thereafter be automatically extended for
additional one (1) year periods unless either party provides the other party one
(1) year's prior written notice of its desire to permit this Agreement to expire
without  further  extension  of its term,  in which event this  Agreement  shall
expire  on the day  before  this  Agreement  would  otherwise  be  automatically
extended.  The amendment or termination  of this Agreement  shall not affect the
obligations of an Ordering  Company or Supplier under any then existing Order or
Supplemental Agreement issued under this Agreement.



<PAGE>



                  1A.6 TRANSITION  PERIOD.  Although all terms of this Agreement
are  effective  on the  Effective  Date,  the parties  recognize  that  complete
implementation  of certain terms depends upon the  development and deployment of
necessary practices and systems. Those terms include, but are not limited to:

                  -  Section  2.1 -  Orders  -  Section  2.2 -
Order  Acceptance
                  Section  2.6 - Order  Cancellation  and  Holds
- -  Section  3.1
                  Pricing - Section 3.2 - Invoices and Terms of
Payment  Section
                  5.1 -  Ordering  Companies  Remedies  - Section
5.2  Supplier
                  Performance  - Section 6.21 - Record  Retention
- - Section 8.16
                  Planning Information for Orders for
                         Commercially Available Products

Both parties  agree to use their  reasonable  best efforts to develop and deploy
those  practices  and  systems  underlying  these and other terms as promptly as
possible,  but not later than March 29, 1997.  The  inability of either party to
comply with any of these terms as a result of not having  developed and deployed
such  practices  and systems  prior to March 29,  1997,  will not be construed a
breach  of  contract,  provided,  however,  that if  such  Supplier's  delay  in
developing  and  deploying  necessary  practices  and systems  delays  affording
Ordering  Company the benefits of the Pricing  Agreement,  Supplier shall afford
those benefits to Ordering Company, as promptly as possible,  retroactive to the
Effective Date.

                  1A.7 PURCHASES BY AT&T'S AFFILIATES. This
Agreement shall
govern purchases from Supplier by AT&T, its Affiliates and
Ordering Companies,
but shall not govern purchases by other entities.

                  1A.8 ADDITIONAL TECHNOLOGY RIGHTS. Supplemental Agreements may
provide,  on a case-by-case  basis, for Ordering Company's  ownership (up to and
including  100%  ownership)  of  specified   intellectual   property  rights  in
technology newly developed by Supplier solely on behalf of Ordering Company.  In
the event technology is licensed by Supplier to Ordering  Company,  Supplier may
agree to grant  Ordering  Company (a) the right to make,  have made,  use, sell,
modify,  offer for sale or  import  specified  Products  and  provide  specified
Services  and  (b)  the  title  and  intellectual  property  rights  to  certain
modifications and resulting derivative works made by Ordering Company.

         been consumed in performing the Services; plus

                                    (B) the cost of undelivered
materials (less
         salvage value, if any) planned for use in performance of
this Agreement
         for which irrevocable Work Orders have been placed by
Supplier prior to
         the effective date of cancellation; plus

                                    (C) the cost of any other
capital
         expenditure  that has been incurred in order to perform
the  terminated
         project and that  cannot be  re-applied  by  Supplier to
provide  other
         Services; plus


<PAGE>



                                    (D) the cost to Supplier of
terminating and
         settling any subcontracts.

                           (v) For purposes of this  subparagraph
(a), "salvage
         value"  shall  include  the  proceeds  of the sale of
the  material  to
         another  Ordering  Company and the costs Supplier avoids
as a result of
         its reapplying  materials to meet other needs of Ordering
Company,  the
         needs of other  customers or its own internal  needs
within ninety (90)
         days of Order  cancellation.  Supplier shall make
reasonable efforts to
         maximize   salvage   value.   Upon  written   request,
Supplier  will
         substantiate such avoided costs.

                  (b) HOLDS.  Ordering  Company  may issue  "holds" on Orders or
suspend  performance  under this  Agreement,  in whole or in part,  upon written
notice to Supplier and shall  compensate  Supplier for any  incremental  expense
(including, but not limited to, warehousing, loss, damage and inventory carrying
costs) incurred.  A hold  automatically  converts to an Order cancellation after
thirty (30) days.

                  (c)  CANCELLATION FOR CAUSE. In the event Supplier shall be in
material breach or default of any of the terms, conditions,  or covenants of any
Order or Supplemental Agreement and if such breach or default shall continue for
a period of forty-five  (45) days in 1996 and thereafter  thirty (30) days after
Supplier's  receipt of notice thereof by Ordering Company,  then, in addition to
the remedies specified in Section 5.1, ORDERING  COMPANIES'  REMEDIES,  Ordering
Company  shall have the right to cancel  such Order or  Supplemental  Agreement,
except  to the  extent  that  Products,  Licensed  Materials  or  Services  have
previously been provided pursuant to such Order or Supplemental Agreement.

                  (d) SURVIVAL. The obligations of this Section
2.5 shall
survive termination of this Agreement.

                  2.6 SHIPPING,  PACKING AND DELIVERY. (a) Supplier shall, at no
additional  charge,  pack Products in accordance with its standard practices for
shipments  to Ordering  Company's  locations.  Unless  instructed  otherwise  by
Ordering  Company,  Supplier shall (i) ship Orders as available,  but not before
the customer requested ship date, (ii) ship to the destination designated in the
Order, (iii) mark all subordinate  documents with the Order number, (iv) enclose
a packing  memorandum  with each  shipment,  and when more than one  package  is
shipped,  identify the package containing the memorandum,  and (v) mark Ordering
Company's Order number on all packages and shipping papers.

                  (b)  Where,  in order  to meet  Ordering  Company's  requests,
Supplier packs Products in other than its normal manner,  Ordering Company shall
pay Supplier's  additional  charges for such packing.  Absent written  agreement
otherwise,  Supplier  will deliver  Products and Licensed  Materials to Ordering
Company  FOB  (free  on  board)  the   manufacturing,   warehouse   or  Software
distribution facility of Supplier or its vendor.


<PAGE>



                  (c) Unless otherwise  directed by Ordering  Company,  Supplier
shall (i) ship equipment from its nearest facility or that of its vendor capable
of filling the Order, (ii) use the lowest available rate from Ordering Company's
pre-selected  designated carrier (rail, truck or freight  forwarder),  and (iii)
prepay  transportation  charges at cost as a separate item on Ordering Company's
invoice  when the cost of  transportation  is to be borne by  Ordering  Company.
Ordering  Company  shall  promptly  pay to Supplier  any prepaid  transportation
charges.  Supplier will provide to Ordering Company a transportation factor card
to  be  used  for  estimating   transportation   rates.   Shipping  and  routing
instructions may be furnished or altered by Ordering Company in writing, subject
to additional charges, if applicable.

                  (d) Supplier agrees not to deliver  Products prior to five (5)
business days before the agreed upon delivery date without Ordering Company's
prior written authorization.

                  2.7  TITLE  AND  RISK OF  LOSS.  Title  to and risk of loss to
Products and risk of loss of Licensed  Materials shall pass to Ordering  Company
upon delivery to Ordering Company. For purposes of this clause, "delivery" shall
mean the point at which  Supplier  or  Supplier's  supplier  or agent turns over
possession of the Product or Licensed  Materials to Ordering  Company,  Ordering
Company's employee, Ordering Company's pre-selected designated carrier, Ordering
Company's  warehouse,  or other Ordering Company's agent and not necessarily the
final  destination  shown on the Order.  Ordering  Company shall notify Supplier
promptly of any claim with respect to loss which  occurs while  Supplier has the
risk of loss and shall  cooperate  in every  reasonable  way to  facilitate  the
settlement of any claim.

                                   ARTICLE III
                               PRICES AND PAYMENT

                  3.1  PRICES.  (a) To the extent  Ordering  Company's  Order is
subject to a firm price  quotation made by Supplier,  prices,  fees, and charges
("Prices")  shall be as set  forth in  Supplier's  firm  price  quotation  or as
specified in the governing  Supplemental  Agreement.  In all other cases, Prices
shall be as set  forth in the  Product  Information  Catalog  Extraction  System
("PRICES")  which  provides  toll free  access to  Supplier's  complete  Product
listing or in ELIB (electronic  library  information  bulletin) or its successor
and will be provided in  electronic  media.  For firm price  quotations,  Prices
shall be valid for thirty (30) days from the date of the quotation. Prices shall
be applied based upon the date Supplier receives Ordering  Company's Order. Both
parties  will work  together in the first  quarter of 1996 to develop a plan for
the migration to PRICES.

                  (b) The  database for pricing of all  Standard
Service  Units
("SSU's") Products and Services is Service Unit Dictionary System
("SUDS").

                  (c)  Where  Supplier  is  not  performing  installation,   all
expenses after shipment from Supplier's  manufacturing or software  distribution
facility  shall  be paid by  Ordering  Company.  If  Supplier  pays  any of such
expenses, they shall be borne by Ordering Company plus


<PAGE>



a fifteen  percent  (15%)  administration  fee.  Supplier  will not  incur  such
expenses  unless it is requested to do so in writing by Ordering  Company (which
request shall constitute  Ordering Company's  agreement to pay Supplier for such
expenses).

                  (d) Notwithstanding the foregoing, if Supplier is delayed from
completion of an Order due to any change  requested by Ordering  Company or as a
result of delay by Ordering  Company in furnishing  information or in performing
its obligations  (including site preparation),  Supplier's prices are subject to
change to the extent that Supplier incurs costs for such delay.

                  (e) Unless expressly stated in writing,  Supplier's prices are
exclusive of charges for  transportation  and other  related  Services,  and any
sales or other tax or duty which Supplier may be required to collect or pay upon
the ordered transaction. Supplier shall include these items as separate items in
its invoiced prices to Ordering  Company.  Ordering Company shall be responsible
for prepaid  transportation  paid by Supplier.  Billable premium  transportation
will be used only with Ordering Company's concurrence.

                  (f)  Supplier may amend its pricing  schedules  once every six
(6) months by  providing  sixty  (60) days'  prior  written  notice.  Unless the
parties agree otherwise in writing,  Supplier's unaccepted firm price quotations
may be amended on ten (10) days'  written  notice.  Such  changes in  Supplier's
pricing shall apply only to Orders  received on or after the  effective  date of
such price changes.

                  (g) In addition to the applicable Price,  reasonable  expenses
for  travel  and  living of  Supplier's  personnel  while on travel  assignments
outside the local area,  approved by Ordering  Company,  shall be  reimbursable.
Such  approval may be written or oral and on an  individual  case basis or for a
category of such  assignments.  If oral approval is given,  it shall be followed
with a written  approval in ten (10) days.  Supplier  shall submit  invoices for
reimbursable  travel and living expenses  promptly upon completion of the travel
events.  Supplier  shall list the travel and living charges as separate items on
each invoice. Supplier shall retain all records in accordance with IRS standards
of such  charges for a period of not less than one (1)  calendar  year after the
expiration of the travel  assignment.  Upon reasonable request in the event of a
question,  Supplier shall make such records available for inspection by Ordering
Company.

                  3.2 INVOICES AND TERMS OF PAYMENT.

                  (a) FOR  CALENDAR  YEAR  1996.  Invoices  and terms of payment
shall be  mutually  agreed to by both  parties no later than March 1, 1996.  The
intent is that both  parties  will plan a  movement  toward the terms of Section
3.2(b),  INVOICES  AND TERMS OF  PAYMENT,  and away from the  current  practice,
NS/NSD  Payment and Invoicing  Policy dated January 30, 1995. The principles for
1996 which the parties will strive to meet will  include (i) the  provision of a
single bill per order on last  shipment;  (ii) such bill shall not be  submitted
manually;   (iii)  billing  upon  shipment  for  Products,   Licensed  Materials
(including  transportation  charges and taxes, if applicable)  and  Engineering,
except engineering Services associated with


<PAGE>



outside plant  construction;  (iv) billing for  Installation  upon  Installation
Complete Date; and (v) implementation on or before April 1, 1996.

                  (b) AFTER 1996.

                   (i) Products,  Licensed Materials  (including  transportation
charges and taxes, if applicable),  and Engineering Services, except engineering
Services associated with outside plant construction, shall be billed by Supplier
when last shipment on an Order is made, or as soon thereafter as practical;

                           (ii) Installation shall be billed upon
Acceptance;

                           (iii) Engineering Services associated
with outside
plant construction shall be billed as performed or, at Supplier's
discretion, on
a monthly basis;

                           (iv) Consulting, design, outside plant
construction,
system integration and program management  Services shall be billed, as mutually
agreed to by the parties (1) on a progress  basis based on the percentage of job
completed up to  eighty-five  percent of the charge or, (2) on a monthly  basis.
Final billing for such Services will be invoiced when such Service is completed;

                           (v) Unless otherwise agreed to,
Maintenance Services
shall be billed monthly, in advance. Supplier will work with Ordering Company to
minimize  the  number of bills  Ordering  Company  receives  each month for such
Services.  If Ordering  Company  requests  quarterly or annual  invoicing,  such
invoicing shall be rendered in advance of such Services;

                  (vi) Payment for generally available Licensed
Material is payable in full upon delivery to First Field
Application; and

                           (vii) Software and/or other technology
development
for  small  projects  (i.e.  less  than or  equal  to  fifteen  million  dollars
($15,000,000)  and less than or equal to twelve (12) months)  shall be billed as
follows:  ten percent (10%) at  commitment  (i.e.,  signing of contract),  forty
percent (40%) upon delivery of the Software to the  Integrated  Test Network (if
the Software  will not be tested in the ITN,  this forty  percent  (40%) payment
shall be due upon  delivery to the First Field  Application),  and fifty percent
(50%)  when  Software  is ready  for  deployment,  or  thirty  (30)  days  after
Acceptance  of the  Software in the First Field  Application,  whichever  occurs
sooner.  Billing for Software and/or other  technology  development for projects
other  than  small  projects  as defined  in the  preceding  sentence,  shall be
determined  on a case by case basis.  The parties will conform the  Supplemental
Agreements to this Section 3.4(b)(vii) by March 31, 1996.

                  (c) Ordering Company shall pay such invoiced amounts, less any
items known then to be disputed  items,  within  thirty (30) days of the date of
Supplier's  invoice.  Ordering  Company  shall  notify  Supplier of any disputed
invoice within eighteen (18) months from the date of the invoice. Such notice of
dispute shall not excuse Ordering Company from


<PAGE>



timely payment of the undisputed portion(s) of any invoice containing a disputed
portion.  Supplier may apply any credit which  remains  outstanding  in favor of
Ordering  Company to the oldest  undisputed  invoice  which  remains in Ordering
Company's account, unless directed otherwise by Ordering Company.

                  (d) Unless otherwise agreed,  payment of all amounts contained
in this  Agreement  shall be made in United States dollars and invoices shall be
rendered  in the same  currency.  Unless  otherwise  agreed to by  Supplier  and
Ordering Company,  payments shall be made by electronic  transfer to the account
and address  indicated by Supplier and shall  reference the  invoice(s) to which
they relate.

                  (e) AT&T  guarantees  payment in United States  dollars of the
obligations of Ordering  Companies that are not Affiliates of AT&T on any Orders
placed pursuant to this  Agreement.  Payment shall be made by AT&T within thirty
(30) days after  receipt of invoice of a guaranteed  payment.  Such invoice will
only be issued to AT&T  after  Supplier  has made  reasonable  efforts to obtain
payment from Ordering  Company.  Ordering  Companies that are Affiliates of AT&T
shall  bear  sole  responsibility  for  the  performance  of  their  obligations
hereunder.

                  3.3 TAXES. (a) Ordering Company shall bear all taxes,  levies,
duties and other  similar  charges  (and any related  interest  and  penalties),
however  designated,  (herein  referred to as "Tax")  imposed as a result of the
existence or operation of this Agreement,  Order or any Supplemental  Agreement,
including  but not  limited to any tax which  Ordering  Company is  required  to
withhold,  collect  or deduct  from  payments  to  Supplier,  except (i) any tax
imposed upon Supplier in a jurisdiction outside the United States if such tax is
allowable as a credit  against the United States  income taxes of Supplier;  and
(ii) any net income  tax  imposed  upon  Supplier  by the  United  States or any
governmental  entity  within the United States proper (the fifty (50) states and
the District of Columbia including, but not limited to counties,  municipalities
and other  localities).  In order for the  exception  contained in (i) to apply,
Ordering  Company must furnish Supplier with such evidence as may be required by
United States taxing  authorities  to establish  that such Tax has been paid, if
any, so Supplier may claim the credit.

                  (b) If Ordering  Company is required to bear a tax pursuant to
paragraph (a) above,  Ordering  Company shall pay to Supplier or the appropriate
government  entity  or taxing  authority,  such Tax and  other  charges  and any
additional  amounts as are necessary to ensure that the net amounts  received by
Supplier  after all such  payments  or  withholdings  equal the amounts to which
Supplier is  otherwise  entitled  under this  Agreement  as if such Tax or other
charges did not exist.

                  (c) If  Ordering  Company  is  exempt  from any Tax,  Ordering
Company shall  provide  Supplier  with all required  documentation  necessary to
establish  Ordering  Company's exempt status.  Ordering Company hereby agrees to
indemnify  Supplier from any Tax,  including  penalties and interest,  resulting
from Supplier's reliance on Ordering Company's claim of exempt status.


<PAGE>



                  (d)  If   Ordering   Company   disputes   in  good  faith  the
applicability  of any Tax imposed as a result of the  existence  or operation of
this Agreement,  Ordering  Company,  at its own expense and in its own name, may
contest the taxing jurisdiction of the disputed Tax. In the event the applicable
law  requires  that such  contest  must be taken in the name of  Supplier  only,
Supplier  shall in good faith and with due diligence at Ordering  Company's sole
expense  contest the  imposition of such Tax provided that (i) Supplier will not
be required to pursue such  contest if the action will result in a lien  against
Supplier for which Ordering Company has not adequately  indemnified  Supplier or
(ii) will result in a penalty being assessed against Supplier for which Ordering
Company has not adequately indemnified Supplier.


                                   ARTICLE IV
                          INTELLECTUAL PROPERTY RIGHTS

             4.1 USE OF INFORMATION.  (a) All technical and business Information
disclosed  by one  party  to the  other  subsequent  to the  execution  of  this
Agreement  in  whatever  form  recorded   which  is  marked   "proprietary"   or
"confidential"  or bears a legend or notice  restricting  its use,  copying,  or
dissemination  or, if not in tangible form, is described as being proprietary or
confidential  at the time of  disclosure  and is  subsequently  summarized  in a
writing so marked and delivered to the  receiving  party within thirty (30) days
of disclosure to the receiving party shall remain the property of the furnishing
party. Similarly,  all technical and business Information disclosed by one party
to the other party prior to the execution of this Agreement and described at the
time of disclosure by the furnishing party as being  proprietary or confidential
or known by the party receiving disclosure of such Information to be proprietary
or confidential shall remain the property of the furnishing party (regardless of
whether it is ever recorded in tangible form).

          (b) The furnishing  party grants the receiving  party the right to use
such Information  only as follows:  Such Information (i) shall not be reproduced
or copied, in whole or part, except for use as authorized in this Agreement; and
(ii) shall,  together with any full or partial  copies  thereof,  be returned or
destroyed  when  no  longer  needed.   Supplier  shall  use  Ordering  Company's
Information  only for the  purpose  of  performing  under  this  Agreement,  and
Ordering  Company shall use Supplier's  Information  only (i) to order Products,
Licensed Materials or Services;  (ii) to evaluate Supplier's Products,  Licensed
Materials or Services; or (iii) to install,  operate and maintain the particular
Products  or  Licensed  Materials  for which  such  Information  was  originally
furnished.  Unless the furnishing party consents in writing,  such  Information,
except for that part, if any, which was previously  known to the receiving party
free of any  confidential  obligation,  or which becomes  generally known to the
public  through  acts  not  attributable  to the  receiving  party,  or  which a
receiving  party  receives from a third party without  restriction,  or which is
independently  developed by the receiving party,  shall be held in confidence by
the receiving  party. The receiving party may disclose such Information to other
persons, upon the furnishing party's prior written authorization,  but solely to
perform  acts which this clause  expressly  authorizes  the  receiving  party to
perform itself and further provided that


<PAGE>



such other person agrees in writing (a copy of which writing will be provided to
the furnishing  party at its request) to the same  conditions  respecting use of
Information  contained  in this  clause and to any other  reasonable  conditions
requested  by  the  furnishing   party.  The  contents  of  this  Agreement  are
confidential  and  shall not be  disclosed  by  either  party to third  parties,
without the prior written agreement of both parties hereto, except to the extent
required  by  applicable  law,  a  court  or  regulatory   agency  of  competent
jurisdiction.

                  (c) Each  party  shall be  liable  to the  other  for  damages
resulting  from  violation of this Section 4.1. Those damages shall be unlimited
as to nature and limited as to amount to thirty  million  dollars  ($30,000,000)
per occurrence.

                  4.2 INFRINGEMENT AND MISAPPROPRIATION. (a) In the event of any
claim,  action,  proceeding  or suit by a third party against  Ordering  Company
alleging an infringement of any patent, copyright, trademark or misappropriation
of a trade secret  recognized in any jurisdiction  where an Ordering Company may
lawfully use or operate Products or Licensed Materials purchased  hereunder,  or
if by reason of the use, in accordance  with Supplier's  Specifications,  in any
such jurisdiction of any Products or Licensed Materials furnished by Supplier to
an Ordering Company under this Agreement, Supplier, at its expense, shall defend
Ordering Company,  subject to the conditions and exceptions stated in Paragraphs
(b), (c), (d), and (e) below.  Supplier shall reimburse Ordering Company for all
costs,  expenses or attorneys'  fees incurred at Supplier's  written  request or
authorization,  and shall  indemnify  Ordering  Company  against  any  liability
assessed  against  Ordering  Company  by  final  judgment  on  account  of  such
infringement or violation arising out of such use. In no event shall Supplier be
liable for Ordering Company's consequential damages.

                  (b) If Ordering  Company's  use is  enjoined or in  Supplier's
opinion  is  likely to be  enjoined,  Supplier  shall,  at its  expense  use its
reasonable best efforts,  to either (i) replace the enjoined Product or Licensed
Materials  furnished  pursuant to this Agreement  with a substitute  free of any
infringement;  (ii)  modify it so that it will be free of the  infringement;  or
(iii)  procure for Ordering  Company a license or other right to use it. If none
of the foregoing options is achievable through reasonable best efforts, Supplier
shall remove the enjoined Product or Licensed  Materials and refund or credit to
Ordering Company any amounts paid to Supplier  therefor less a reasonable charge
for depreciation and any actual period of use by Ordering Company.  In no event,
however,  shall  Supplier's  liability  under  this  Section  4.2(b)  exceed the
amount(s)  paid by Ordering  Company to  Supplier to purchase  the Product or to
obtain the right to use the Licensed  Materials which are alleged to violate the
rights described in Paragraph (a) above.

                  (c) Ordering Company shall give Supplier prompt written notice
of all such claims,  actions,  proceedings  or suits  alleging  infringement  or
violation and Supplier shall have full and complete authority to assume the sole
defense thereof,  including appeals, and to settle same. Ordering Company shall,
upon Supplier's request and at Supplier's  expense,  furnish all information and
assistance  available to Ordering  Company and cooperate in every reasonable way
to  facilitate  the  defense  and/or  settlement  of  any  such  claim,  action,
proceeding or suit.


<PAGE>



                  (d) No  undertaking of Supplier under this clause shall extend
to any such alleged  infringement or violation to the extent that it: (i) solely
arises from  adherence to design  modifications,  Specifications,  drawings,  or
written  instructions  which Supplier is directed by Ordering  Company to follow
but only if such alleged  infringement  or  misappropriation  does not reside in
material  of  Supplier's  origin,  design  or  selection;  or (ii)  arises  from
adherence to instructions to apply Ordering Company's  trademark,  trade name or
other company identification; or (iii) resides in equipment or Software which is
furnished by Ordering Company to Supplier for use under this Agreement;  or (iv)
arises  from use of the Product or  Licensed  Materials  provided by Supplier in
combination  with any item not furnished  directly by Supplier;  or (v) is based
upon modification made by Ordering Company of any Product or Licensed Materials;
or (vi)  arises  from use of any  Product or  Licensed  Material in a manner for
which it was not  designed.  In the foregoing  cases  numbered (i) through (vi),
Ordering  Company shall defend and save Supplier  harmless,  subject to the same
terms and  conditions and  exceptions  stated above,  with respect to Supplier's
rights and obligations under this clause.

                  (e) The liability of Supplier,  AT&T and Ordering Company with
respect to any and all claims,  actions,  proceedings  or suits by third parties
alleging infringement of patents, trademarks or copyrights or violation of trade
secrets or proprietary rights because of, or in connection with, any Products or
Licensed Materials  furnished pursuant to this Agreement shall be limited to the
specific undertakings contained in this Section 4.2.

                  4.3 NO PATENT  LICENSES.  Nothing  contained  herein  shall be
construed as  conferring  by  implication,  estoppel or otherwise any license or
right  under  any  patent,  except  that  which is  essential  to the use of the
Products and/or Licensed Materials as provided by Supplier, and provided however
that  this  Section  4.3  shall  not  limit  or  modify  any of the  rights  and
obligations of the Intellectual  Property Agreements or the Supplemental General
Purchase  Agreement,  No.  LC3757D,  both  executed as of this date as Ancillary
Agreements to the Separation and Distribution  Agreement.  Supplier shall retain
all ownership rights in all intellectual property used or embodied in Supplier's
Products,  Licensed Materials and Service unless otherwise  expressed herein, or
in a Supplemental Agreement.

                  4.4  TRADEMARKS.  (a) Subject to the  provisions  of the Brand
License  Agreement,  executed as of this date as an  Ancillary  Agreement to the
Separation and  Distribution  Agreement,  each party shall have the right to use
Products and Licensed Materials which bear the other party's  trademarks,  trade
name, logos, trade devices,  service marks, symbols, and codes, unless otherwise
directed by that party to remove such indicia.

                  (b) Except as provided in Section s 4.4 (a) above,  each party
(including  in the  case  of  AT&T,  each  Ordering  Company)  shall  not use in
advertising or otherwise,  any of the other party's trade name, logo, trademark,
trade device, service mark, symbol, code or Specification,  or any abbreviation,
contraction,  or simulation  thereof,  without the prior written consent of such
party. Neither party shall claim any ownership therein, and any such usage shall
inure to the benefit of the party which owns such trade name, logo, trademark,

<PAGE>

trade device, service mark, symbol, code or Specification.

                  4.5 PROPRIETARY  NOTICE.  Ordering Company shall reproduce and
include any Supplier copyright or proprietary notice on all authorized copies of
Licensed  Materials.  Ordering Company shall also mark all media containing such

         (a) An Ordering  Company's  exclusive remedies and the entire liability
of Supplier,  Supplier's  Affiliates and their  employees and agents,  and their
vendors for any claim,  loss, damage or expense of Ordering Company or any other
entity arising out of this Agreement or any Supplemental  Agreement,  or the use
or performance of any Product,  Licensed Materials,  or Services,  whether in an
action for or  arising  out of breach of  contract,  warranty,  tort,  including

remedy shall include those set forth in the applicable "warranty" clause;

                           (iv) For third party claims against
Ordering Company
for personal injury and property damage for which Supplier is held
liable -- the
remedy afforded by the governing law;

                           (v) For tangible property damage to
Ordering Company
caused by Supplier's negligence -- the amount of the direct

or Services on Supplier's  scheduled  delivery date and (ab)  thereafter  thirty
(30) days from receipt of such notice, the following remedies shall apply:


<PAGE>



                                    (A) Ordering Company may
cancel the Order
without incursion of cancellation fees; and,

                                    (B) Ordering Company may
request and
Supplier will reduce AT&T's volume purchase commitment by an amount equal to the
value of the Order. In addition, if a worldwide supply shortage exists, Ordering
Company may request and, upon such request, shall receive priority on allocation
of such  delivered  Products,  Licensed  Materials  or  Services  in a  shortage
condition  based  upon  priority  criteria  agreed to between  Supplier  and its
affected customers established for the particular shortage condition.

                  (b)  Notwithstanding any other provision of this
Agreement and
except as provided in Section 5.1(a)(ii) above,  ORDERING
COMPANIES'  REMEDIES,
Supplier,  Supplier's  Affiliates  and their  employees  and  agents,  and their
vendors shall not be liable for any consequential  damages in the nature of lost
profits,  revenues  or  savings  arising  out of this  Agreement,  or the use or
performance  of any Product,  Licensed  Materials,  or  Services,  whether in an
action for or  arising  out of breach of  contract,  warranty,  tort,  including
negligence, or strict liability.

                  (c) Other than damages pursuant to Section  5.1(a)(ii)  above,
ORDERING COMPANIES'  REMEDIES,  Supplier's total liability for incidental and/or
consequential  damages and damages  resulting from network outages which must be
reported  by  Ordering  Company  to the  Federal  Communications  Commission  in
accordance  with its rules  ("Network  Outage(s)")  shall not exceed ten million
dollars  ($10,000,000)  per  occurrence  with a total  not to  exceed  of thirty
million dollars ($30,000,000) in any one year. This Section 5.1(c) shall survive
failure of an exclusive or limited remedy.

                  (d) Ordering Company shall give Supplier prompt written notice
of any claim.  Any action or proceeding  against Supplier must be brought within
thirty-six (36) months after the cause of action accrues.


                  (e)  Supplier  acknowledges  that a Network  Outage will cause
damage to AT&T in an amount  impossible  to  ascertain.  Supplier  agrees to pay
AT&T, as liquidated damages and not as a penalty, the sum of one million dollars
($1,000,000)  per  occurrence in the event of a Network  Outage caused solely by
Supplier in  connection  with network  infrastructure  equipment and one hundred
thousand  dollars  ($100,000)  per  occurrence in the event of a Network  Outage
caused  solely by Supplier in connection  with BCS  Products,  whether or not by
breach of warranty and whether before, during or after any Warranty Period. With
respect to a Network Outage caused solely by Supplier in connection with network
infrastructure  equipment,  Supplier's  total  liability for damages for Network
Outages,  including the liquidated damages described herein shall be one million
dollars  ($1,000,000)  per  occurrence not to exceed the amount of three million
dollars  ($3,000,000)  for any calendar year, and Supplier's total liability for
damages  for Network  Outages  for any three (3) year period of this  Agreement,
including the liquidated damages described herein, shall be five million dollars
($5,000,000); provided that AT&T is meeting its obligations specified in Section
1A.3, VOLUME COMMITMENT, and the




<PAGE>



Pricing Agreement.  With respect to Network Outages caused solely by Supplier in
connection  with BCS Products,  Supplier's  total  liability  under this section
shall be one hundred  thousand  dollars  ($100,000) per occurrence not to exceed
the amount of three hundred  thousand  dollars  ($300,000) for any calendar year
,and  Supplier's  total  liability for damages for Network Outages for any three
(3) year period of this Agreement,  including the liquidated  damages  described
herein, shall be five hundred thousand dollars ($500,000); provided that AT&T is
meeting its obligations  specified in Section 1A.3, VOLUME  COMMITMENT,  and the
Pricing Agreement. If, at any time during the term of this Agreement, AT&T fails
to meet its obligations  specified in Section 1A.3, VOLUME  COMMITMENT,  and the
Pricing  Agreement,  it shall not be  entitled  to the  remedy  in this  Section
5.1(e).  Any damages  paid by Supplier  pursuant to this  Subparagraph  shall be
considered  incidental and  consequential  damages subject to the limitations on
AT&T's  right to  recover  same that are set forth in Section  5.1(c),  ORDERING
COMPANIES' REMEDIES.  At AT&T's option, AT&T may take all or part of the payment
as a credit  against any invoice due or to become due to Supplier.  The remedies
available  to AT&T under  Section 5.1,  ORDERING  COMPANIES'  REMEDIES,  and the
foregoing  liquidated  damages shall constitute AT&T's sole and exclusive remedy
for Network  Outages  caused to any extent by  Supplier  during the term of this
Agreement.

                  5.2  SUPPLIER  PERFORMANCE.  AT&T and  Supplier  will  jointly
develop  requirements for an annual Supplier Merit Award by December 1st of each
year for the following  year. For 1996, the  requirements  are listed in Exhibit
5-1. The award  program will  provide that if Supplier  meets or exceeds  either
award performance criteria for receipt of a Supplier Merit Award, AT&T shall:

                           (a) increase its minimum volume
purchase commitment
for the  following  year (if the volume  purchase  commitment  in Section  1A.3,
VOLUME COMMITMENT,  is in effect),  by twenty million dollars  ($20,000,000) for
achieving the on-time delivery criteria and ten million dollars
($10,000,000)
for achieving the FCC reportable incidents criteria or

                           (b) if a volume purchase commitment is
not in effect,
increase its purchase or license of Supplier's Products,  Licensed Materials and
Services for the following  year by twenty  million  dollars  ($20,000,000)  for
achieving the on-time delivery criteria and ten million dollars
($10,000,000)
for achieving the FCC reportable  incidents criteria. A public relations program
will be jointly developed and executed in support of this award program.

                  5.3 INSURANCE.  Supplier  shall maintain and cause  Supplier's
subcontractors  to  maintain  during the term of this  Agreement:  (a)  Workers'
Compensation  insurance as prescribed by the law of the state or nation in which
the work is performed,  (b)  employer's  liability  insurance  with limits of at
least  three  hundred  thousand  dollars  ($300,000)  for each  occurrence;  (c)
comprehensive  automobile  liability  insurance if the use of motor  vehicles is
required,  with limits of at least one  million  dollars  ($1,000,000)  combined
single limit for bodily  injury and  property  damage for each  occurrence,  (d)
Comprehensive General Liability ("CGL") insurance, including Blanket Contractual
Liability and Broad Form Property damage, with limits of at least


<PAGE>





one million dollars  ($1,000,000)  combined single limit for personal injury and
property  damage for each  occurrence;  and (e) if the  furnishing  to  Ordering
Company  (by sale or  otherwise)  of  Products  or  material  is  involved,  CGL
insurance  endorsed  to include  products  liability  and  completed  operations
coverage in the amount of five million dollars ($5,000,000) for each occurrence.
If specifically requested by Ordering Company,  Supplier's  subcontractors shall
furnish,  prior to the  start of work,  certificates  or  adequate  proof of the
foregoing  insurance,   including  copies  of  the  endorsements  and  insurance
policies.  Supplier's  obligations  to maintain  insurance  may be  satisfied by
providing proof of self-insurance in a form satisfactory to Company.

                         ARBITRATION; DISPUTE RESOLUTION

                  5A.1 AGREEMENT TO ARBITRATE.  The  procedures for  discussion,
negotiation  and  arbitration  set forth in this  Article 5A shall  apply to all
disputes,  controversies  or  claims  (whether  sounding  in  contract,  tort or
otherwise)  that may arise out of or related to, or arise under or in connection
with  this  Agreement  or  any  Supplemental   Agreement,  or  the  transactions
contemplated  hereby or thereby  (including  all actions taken in furtherance of
the transactions contemplated hereby or thereby on or prior to the date hereof),
or the  commercial  or economic  relationship  of the parties  relating  hereto,
between the  parties.  Each party agrees that the  procedures  set forth in this
Article  5A shall  be the  sole and  exclusive  remedy  in  connection  with any
dispute,  controversy  or claim  relating  to any of the  foregoing  matters and
irrevocably   waives  any  right  to  commence  any  Action  in  or  before  any
Governmental Authority except as expressly provided in Section 5A.7(b),  CERTAIN
ADDITIONAL  MATTERS,  and 5A.8,  LIMITED COURT ACTIONS,  below and except to the
extent  provided  under the  Arbitration  Act in the case of judicial  review of
arbitration results or awards. Each party on behalf of itself irrevocably waives
any right to any trial by jury with respect to any such claim,  controversy,  or
dispute.





<PAGE>



                  5A.2  ESCALATION.  (a) It is the intent of the  parties to use
their respective  reasonable best efforts to resolve  expeditiously any dispute,
controversy  or claim between or among them with respect to the matters  covered
hereby  that may arise  from time to time on a  mutually  acceptable  negotiated
basis.  In  furtherance  of the  foregoing,  any party  involved  in a  dispute,
controversy or claim may deliver a notice (an "Escalation  Notice") demanding an
in person meeting involving  representatives of the parties at a senior level of
management of the parties (or if the parties agree, of the appropriate strategic
business  unit or division  within such entity).  A copy of any such  Escalation
Notice shall be given to the General  Counsel,  or like officer or official,  of
each party involved in the dispute, controversy or claim (which copy shall state
that it is an  Escalation  Notice  pursuant  to  this  Agreement).  Any  agenda,
location or procedures for such discussions or negotiations  between the parties
may be established by the parties from time to time; provided, however, that the
parties shall use their  reasonable best efforts to meet within thirty (30) days
of the Escalation Notice.

                  (b) The parties may, by mutual  consent,  retain a mediator to
aid the parties in their  discussions and  negotiations by informally  providing
advice to the parties.  Any opinion  expressed by the mediator shall be strictly
advisory  and shall  not be  binding  on the  parties,  nor  shall  any  opinion
expressed by the mediator be  admissible  in any  arbitration  proceedings.  The
mediator  may be chosen  from a list of  mediators  previously  selected  by the
parties or by other  agreement of the parties.  Costs of the mediation  shall be
borne  equally by the parties  involved  in the  matter,  except that each party
shall be responsible for its own expenses.  Mediation is not a prerequisite to a
demand for arbitration under Section 5A.3, DEMAND FOR ARBITRATION.
   

                 5A.3.  DEMAND FOR ARBITRATION.  (a) At any time after the first
to occur of (i) the date of the meeting actually held pursuant to the applicable
Escalation  Notice  or (ii)  forty  five  (45) days  after  the  delivery  of an
Escalation  Notice (as applicable,  the  "Arbitration  Demand Date"),  any party
involved in the dispute,  controversy or claim (regardless of whether such party
delivered  the  Escalation  Notice)  may,  unless the  applicable  deadline  has
occurred,  make a written  demand (the  "Arbitration  Demand  Notice")  that the
dispute be resolved by binding  arbitration,  which  Arbitration  Demand  Notice
shall be given in the  manner set forth in Section  6.3,  NOTICES.  In the event
that any party shall deliver an Arbitration Demand Notice to another party, such
other party may itself deliver an Arbitration  Demand Notice to such first party
with respect to any related dispute,  controversy or claim with respect to which
the applicable  deadline has not passed without the requirement of delivering an
Escalation  Notice.  No party may assert  that the failure to resolve any matter
during  any  discussions  or  negotiation,  the  course of  conduct  during  the
discussions  or  negotiations  or the failure to agree on a mutually  acceptable
time,  agenda,  location  or  procedures  for  the  meeting,  in each  case,  as
contemplated  by  Section  5A.2,  ESCALATION,  is  prerequisite  to a demand for
arbitration  under this Section  5A.3.  In the event that any party  delivers an
Arbitration Demand Notice with respect to any dispute, controversy or claim that
is the subject of any then  pending  arbitration  proceeding  or of a previously
delivered Arbitration Demand Notice, all such disputes, controversies and claims
shall be resolved in the arbitration  proceeding for which an Arbitration Demand
Notice was first delivered unless the




<PAGE>



arbitrator in his or her sole discretion determines that it is
impracticable or
otherwise inadvisable to do so.

                  (b) Any Arbitration  Demand Notice may be given until one year
and forty five (45) days after the later of the  occurrence  of the act or event
in the exercise of reasonable due diligence  giving rise to the underlying claim
or the date on which such act or event was, or should have been,  discovered  by
the party asserting the claim (as applicable, and as it may in a particular case
be specifically extended by the parties in writing, the "Applicable  Deadline").
Any discussions, negotiations or mediations between the parties pursuant to this
Agreement or otherwise will not toll the Applicable  Deadline  unless  expressly
agreed  in  writing  by the  parties.  Each  of the  parties  agrees  that if an
Arbitration Demand Notice with respect to a dispute, controversy or claim is not
given prior to the  expiration of the Applicable  Deadline,  as between or among
the  parties,  such  dispute,  controversy  or claim will be barred.  Subject to
Section 5A.7 (d), CERTAIN ADDITIONAL  MATTERS,  and 5A.8, LIMITED COURT ACTIONS,
upon delivery of an  Arbitration  Demand  Notice  pursuant to Section 5A.3 (b) ,
DEMAND  FOR  ARBITRATION,   prior  to  the  Applicable  Deadline,  the  dispute,
controversy  or claim shall be decided by a sole  arbitrator in accordance  with
the rules set forth in this Article 5A.

                  5A.4. ARBITRATORS. (a) Within fifteen (15) days
after a valid
Arbitration Demand Notice is given, the parties involved in the
dispute,
controversy or claim referenced therein shall attempt to select a
sole
arbitrator satisfactory to all such parties.

                  (b) In the event  that such  parties  are not able to  jointly
select a sole arbitrator within such fifteen (15) day period, such parties shall
each appoint an arbitrator (who need not be  disinterested  as to the parties or
the matter)  within thirty (30) days after  delivery of the  Arbitration  Demand
Notice.  If one party  appoints  an  arbitrator  within such time period and the
other party or parties  fail to appoint an  arbitrator  within such time period,
the  arbitrator  appointed by the one party shall be the sole  arbitrator of the
matter.

                  (c)  In the  event  that a  sole  arbitrator  is not  selected
pursuant  to  paragraph  (a) or (b)  above  and,  instead,  two (2) or three (3)
arbitrators  are  selected  pursuant to  paragraph  (b) above,  the two or three
arbitrators  will, within thirty (30) days after the appointment of the later of
them to be appointed,  select an additional arbitrator who shall act as the sole
arbitrator of the dispute. After selection of such sole arbitrator,  the initial
arbitrators shall have no further role with respect to the dispute. In the event
that the  arbitrators  so  appointed do not,  within  thirty (30) days after the
appointment of the later of them to be appointed,  agree on the selection of the
sole arbitrator,  any party involved in such dispute may apply to CPR, New York,
New York, to select the sole  arbitrator,  which selection shall be made by such
organization  within  thirty (30) days after such  application.  Any  arbitrator
selected  pursuant to this paragraph (c) shall be disinterested  with respect to
any of the  parties  and the matter  and shall be  reasonably  competent  in the
applicable subject matter.

                  (d) The sole  arbitrator  selected  pursuant to paragraph (a),
(b) or (c)  above  will set a time for the  hearing  of the  matter  which  will
commence no later than ninety (90) days after the





<PAGE>




date of appointment of the sole arbitrator pursuant to paragraph (a), (b) or (c)
above,  and which hearing will be no longer than thirty (30) days (unless in the
judgment of the arbitrator the matter is unusually complex and sophisticated and
thereby  requires a longer time,  in which event such hearing shall be no longer
than ninety (90) days).  The final decision of such  arbitrator will be rendered
in writing to the parties not later than sixty (60) days after the last  hearing
date, unless otherwise agreed by the parties in writing.

                  (e) The place of any arbitration hereunder will
be New Jersey,
unless otherwise agreed by the parties.

                  5A.5  HEARINGS.  Within the time period  specified  in Section
5A.4 (d),  ARBITRATORS,  the matter shall be presented  to the  arbitrator  at a
hearing  by means of written  submissions  of  memoranda  and  verified  witness
statements, filed simultaneously, and responses, if necessary in the judgment of
the arbitrator or both parties.  If the arbitrator deems it to be essential to a
fair resolution of the dispute, live cross-examination or direct examination may
be permitted,  but is not generally contemplated to be necessary. The arbitrator
shall actively  manage the arbitration  with a view to achieving a just,  speedy
and  cost-effective  resolution  of  the  dispute,  claim  or  controversy.  The
arbitrator may, in his discretion, set time and other limits on the presentation
of each party's case, its memoranda or other submissions,  and refuse to receive
any proffered  evidence,  which the arbitrator,  in his discretion,  finds to be
cumulative,  unnecessary,  irrelevant  or of low  probative  nature.  Except  as
otherwise  set forth  herein,  any  arbitration  hereunder  will be conducted in
accordance  with the CPR  Rules for  Non-Administered  Arbitration  of  Business
Disputes  (except  that the fee  schedule of the CPR will not apply).  Except as
expressly set forth in Section 5A.8(b),  LIMITED COURT ACTIONS,  the decision of
the arbitrator  will be final and binding on the parties,  and judgment  therein
may be had and will be  enforceable  in any court having  jurisdiction  over the
parties.  Arbitration  awards will bear  interest at an annual rate of the Prime
Rate Plus two percent (2%) per annum.  To the extent that the provisions of this
Agreement and the prevailing  rules of the CPR conflict,  the provisions of this
Agreement shall govern.


                  5A.6  DISCOVERY  AND  CERTAIN  OTHER  MATTERS.  (a) Any  party
involved in the applicable dispute may request limited document  production from
the other party or parties of specific and expressly  relevant  documents,  with
the reasonable  expenses of the producing party incurred in such production paid
by the requesting  party. Any such discovery (which rights to documents shall be
substantially  less than document  discovery rights prevailing under the Federal
Rules of Civil Procedure) shall be conducted  expeditiously  and shall not cause
the hearing provided for in Section 5A.5, HEARINGS,  to be adjourned except upon
consent  of  all  parties  involved  in  the  applicable   dispute  or  upon  an
extraordinary  showing of cause demonstrating that such adjournment is necessary
to  permit  discovery  essential  to a  party  to the  proceeding.  Depositions,
interrogatories or other forms of discovery (other than the document  production
set forth above) shall not occur except with the consent of the parties involved
in the applicable dispute.  Disputes concerning the scope of document production
and  enforcement  of the document  production  requests  will be  determined  by
written agreement of the parties




<PAGE>



involved in the applicable dispute or, failing such agreement,  will be referred
to the arbitrator for resolution.  All discovery requests will be subject to the
parties'  rights to claim any applicable  privilege.  The arbitrator  will adopt
procedures to protect such rights and to maintain the confidential  treatment of
the arbitration  proceedings  (except as may be required by law). Subject to the
foregoing,  the arbitrator shall have the power to issue subpoenas to compel the
production of documents relevant to the dispute, controversy or claim.     
                  (b) Except where  contrary to the provisions set forth in this
Agreement or any  Supplemental  Agreement,  the rules of the CPR for  commercial
arbitration  will be applied to all matters of procedure,  including  discovery.
The  arbitrator  shall  have full power and  authority  to  determine  issues of
arbitrability  but shall  otherwise be limited to interpreting or continuing the
applicable  provisions of this  Agreement and will have no authority or power to
limit,  expand,  alter,  amend,  modify,  revoke or  suspend  any  condition  or
provision of the Agreement;  it being understood,  however,  the arbitrator will
have full  authority to  implement  the  provisions  of this  Agreement,  and to
fashion appropriate  remedies for breaches of this Agreement  (including,  other
than in the case of disputes,  controversies  or claims relating to, arising out
of or  resulting  from  Patents  (as such term is defined in the Patent  License
Agreement),   interim  or  permanent  injunctive  relief);   provided  that  the
arbitrator  shall not have (i) any  authority in excess of the authority a court
having  jurisdiction  over the parties and the controversy or dispute would have
absent these arbitration provisions or (ii) any right or power to award punitive
damages.  It is the  intention of the parties that in rendering a decision,  the
arbitrator give effect to the applicable provisions of this agreement and follow
applicable law (it being understood and agreed that this sentence shall not give
rise to a right of judicial review of the arbitrator's award).

                  (c) If a party  fails or refuses to appear at and  participate
in an  arbitration  hearing  after  due  notice,  the  arbitrator  may  hear and
determine the controversy upon evidence produced by the appearing party.

                  (d)  Arbitration  costs  will be borne  equally  by each party
involved in the matter,  except that each party will be responsible  for its own
attorneys  fees and other  costs,  expenses,  including  the costs of  witnesses
selected by such party.

                  5A.7.  CERTAIN ADDITIONAL  MATTERS.  (a) Any arbitration award
shall be a bare award  limited to a holding  for or against a party and shall be
without  findings as to facts,  issues or  conclusions  of law  (including  with
respect to any matters  relating to the validity or infringement of Patents) and
shall be without a statement of the reasoning on which the award rests, but must
be in  adequate  form so that a judgment  of a court may be  entered  thereupon.
Judgment upon any arbitration award hereunder may be entered in any court having
jurisdiction thereof.

                  (b)  Prior to the time at which  an  arbitrator  is  appointed
pursuant  to  Section  5A.4(c),  ARBITRATORS,  any  party  may  seek one or more
temporary restraining orders in a





<PAGE>





court of  competent  jurisdiction  if necessary in order to preserve and protect
the  status  quo.  Neither  the  request  for,  nor grant or denial of, any such
temporary  restraining  order  shall be  deemed a waiver  of the  obligation  to
arbitrate  as set forth  herein and the  arbitrator  may  dissolve,  continue or
modify any such order.  Any such  temporary  restraining  order shall  remain in
effect  until the first to occur of the  expiration  of the order in  accordance
with its terms or the dissolution thereof by the arbitrator.

                  (c) Except as required by law,  the  parties  shall hold,  and
shall cause their respective officers,  directors,  employees,  agents and other
representatives  to hold,  the  existence,  content and result of  mediation  or
arbitration  in confidence in accordance  with the provisions of Section 6.2 and
except as may be  required  in order to enforce  any award.  Each of the parties
shall request that any mediator or arbitrator  comply with such  confidentiality
requirement.

                  (d) In the event  that at any time the sole  arbitrator  shall
fail to serve as an  arbitrator  for any reason,  the parties shall select a new
arbitrator  who  shall be  disinterested  as to the  parties  and the  matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator.  The extent,  if any, to which testimony  previously  given shall be
repeated  or as to  which  the  replacement  arbitrator  elects  to  rely on the
stenographic  record (if there is one) of such testimony  shall be determined by
the replacement arbitrator.


                  5A.8  LIMITED  COURT  ACTIONS.  (a)  Notwithstanding  anything
herein to the contrary,  in the event that any party  reasonably  determines the
amount of  controversy  in any dispute,  controversy  or claim (or any series of
related  disputes,  controversies  or  claims)  under this  Agreement  is, or is
reasonably likely to be, in excess of one hundred million dollars ($100,000,000)
and if such party  desires to commence an Action in lieu of  complying  with the
arbitration  provisions  of this  Article,  such  party  shall  so  state in its
Arbitration  Demand Notice or by notice given to the other parties within twenty
(20) days after receipt of an Arbitration Demand Notice with respect thereto. If
the other parties to the arbitration do not agree that the amount in controversy
in such  dispute,  controversy  or claim (or such  series of  related  disputes,

hundred million dollars ($100,000,000).  The arbitrator shall set a date that is
no later than ten (10) days after the date of his appointment for submissions by

claims)  is, or is  reasonably  likely to be, in excess of one  hundred  million
dollars   ($100,000,000),   the  provisions  of  Sections   5A.4(d),   and  (e),

hereof shall not apply and on or before (but,  except as expressly  set forth in
Section 5A.8(b), not after) the tenth (10th) business day after the date of






<PAGE>





such decision,  any party to the arbitration may commence an Action with respect
to such  dispute,  controversy  or claim (or such  series of  related  disputes,
controversies  or  claims)  in  any  court  of  competent  jurisdiction.  If the
arbitrator does not so determine, the provisions of this Article (including with
respect to time periods) shall apply as if no determinations were sought or made
pursuant to this Section 5A.8.

                  (b) In the event  that an  arbitration  award in excess of one
hundred million dollars  ($100,000,000.) is issued in any arbitration proceeding
commenced  hereunder,  any party may,  within  sixty (60) days after the date of
such  award,  submit  the  dispute,  controversy  or claim (or series of related
disputes,  controversies  or claims)  giving rise  thereto a court of  competent
jurisdiction,  regardless  of whether  such party or any other  party  sought to
commence an action in lieu of proceeding  with  arbitration  in accordance  with
Section 5A.8(a).  In such event, the applicable court may, if it determines that
it would be advisable in connection  with the matter,  allow the parties to seek
additional  discovery  or to present  additional  evidence.  Each party shall be
entitled  to present  arguments  to the court with  respect to whether  any such
additional  discovery  or evidence  shall be  permitted  and with respect to all
other  matters  relating to the  applicable  dispute,  controversy  or claim (or
series of related disputes, controversies or claims).

                  (c)  No  party  shall  raise  as  a  defense  the  statute  of
limitations  if the  applicable  Arbitration  Demand  Notice was delivered on or
prior to the Applicable Deadline and, if applicable,  the matter is submitted to
a court of competent  jurisdiction within the sixty (60) day period specified in
Section 5A.8(b).

                  5A.9. CONTINUITY OF SERVICE AND PERFORMANCE.  Unless otherwise
agreed in writing,  the parties will  continue to provide  service and honor all
other commitments  under this Agreement during the course of dispute  resolution

subject to such dispute, controversy or claim.

                  5A.10.    LAW   GOVERNING    ARBITRATION    PROCEDURES.    The
interpretation of the provisions of this Article 5A, only insofar as they relate

governed by the Arbitration Act and other  applicable  federal law. In all other
respects, the interpretation of this Agreement shall be governed as set forth in
Section 6.19, GOVERNING LAW.

                                   ARTICLE VI
                                  MISCELLANEOUS

                  6.1 EXPORT  CONTROL.  The parties  acknowledge  that Products,
Licensed Materials and Information (including,  but not limited to, Services and
training)  provided  under this  Agreement  are subject to U.S.  export laws and
regulations,  and any use or transfer of such Products and  Information  must be
authorized  under  those  regulations.   AT&T  agrees  that  it  will  not  use,
distribute,   transfer,   or  transmit  the  Products,   Licensed  Materials  or
Information  (even if  incorporated  into other  products)  in violation of U.S.
export regulations. If requested by Supplier, AT&T shall sign written assurances
and other export-related documents as may be






<PAGE>



required for Supplier to comply with U.S. export regulations.  This Section does
not grant AT&T any contractual right to Export Supplier's  Products and Licensed
Materials.  Such  right  shall  only  be  granted  expressly  in  an  applicable
Supplemental Agreement.

                  6.2  PUBLICATION  OF  AGREEMENT.  The parties  shall treat the
provisions  of  this  Agreement  and any  Supplemental  Agreement  or any  Order
submitted  hereunder  as  Information  subject  to the  restrictions  on use and
disclosure  set forth in Section 4.1, USE OF  INFORMATION,  except as reasonably
necessary  for  performance  hereunder  (including   enforcement  of  Supplier's
obligations under the Pricing  Agreement and AT&T's  obligations under Exhibit 1
thereto) and except to the extent  disclosure may be required by applicable laws
or regulations, in which latter case, the party required to make such disclosure
shall promptly  inform the other prior to such  disclosure in sufficient time to
enable  such  other  party  to make  known  any  objections  it may have to such
disclosure.   The  party  required  to  disclose  information   concerning  this
Agreement, a Supplemental Agreement or Order to a third party in accordance with
the previous  sentence  shall take all  reasonable  steps to secure a protective
order or otherwise  assure that the Agreement,  Supplemental  Agreement or Order
will be withheld from the public record.

                  6.3  NOTICES.  All notices  under this  Agreement  shall be in
writing (except where otherwise stated) by confirmed, facsimile, electronic mail
or similar communication, or by certified or registered mail.
Within ten (10)
days  following  the  Effective  Date,  the parties will  exchange the names and
addresses  to whom the notices  should be sent. A notice shall be deemed to have
been given, if by electronic mail,  facsimile or similar  communication,  on the
date it is sent,  and, if by certified  or  registered  mail,  on the date it is
deposited postage prepaid. Communications may be made orally between the parties
when the nature of the  communication  does not require written  notice.  In the
event of a change  of  address,  written  notice of such  change  shall be given
promptly to the other party.

                  6.4 ORDERING  COMPANY'S  RESPONSIBILITY.  (a) Ordering Company
shall, at no charge to Supplier, provide Supplier with notice of site conditions
known to Ordering  Company and such  electrical  and  environmental  conditions,
technical  information,  data, technical support or assistance as may reasonably
be required by Supplier to fulfill its  obligations  under this  Agreement,  any
Supplemental  Agreement  or Order.  If  Ordering  Company  fails to provide  the
required  conditions,   technical  information,  data,  support  or  assistance,
Supplier shall be discharged from its obligations to perform  hereunder for that
Order.  Where  Services are to be  performed  by Supplier in buildings  owned or
controlled  by Ordering  Company,  Ordering  Company  shall be  responsible  for
ensuring  that the  premises  where the work is to be  performed by Supplier are
accessible  to Supplier  and ready and suitable for the Services to be performed
in   accordance   with   Supplier's   reasonable   site-preparation   conditions
communicated in advance to Ordering Company.  Such conditions  include,  but are
not limited to, (a) site readiness and (b) access to adequate  storage space for
tools and other small items  necessary  for the work,  working  space,  personal
facilities,  heat,  light,  ventilation,   telephone,  electrical  current,  and
outlets, all provided within a reasonable distance of the area where the work is
to be performed, if available.





<PAGE>



                  (b) Supplier's  representative shall have the right to inspect
the site prior to Service Start Date.  If Ordering  Company or its other vendors
or contractors fail to timely complete site readiness or if the work of Ordering
Company  or  its  other  vendors  or  contractors   interferes  with  Supplier's
performance,  the applicable  Completion  Date shall be extended as necessary to
compensate  for such  delay or  interference  and  additional  charges  shall be
invoiced to recover the additional  expenses incurred by Supplier as a result of
such failure or interference.  Moreover,  should Ordering Company fail to comply
with the reasonable site-preparation conditions after Supplier provides Ordering
Company notice,  Supplier may perform such work or furnish such items and charge
Ordering  Company  for them in  addition  to the  prices  otherwise  charged  by
Supplier for such Services.

                  6.5  SUPPLIER'S  RESPONSIBILITY.  (a)  Supplier  shall  become
acquainted  with  conditions  governing  the  delivery,  receipt  and storage of
materials  at the site of the work so that  Supplier  will  not  interfere  with
Ordering Company's operations.  For items other than those identified in Section
6.4,  ORDERING  COMPANY'S   RESPONSIBILITY,   above,   storage  space  will  not
necessarily be provided  adjacent to the site of the work.  Therefore,  Supplier
shall be expected to select,  uncrate,  remove and transport  materials from the
storage areas provided. Except to the extent that Supplier's property located on
Ordering   Company's  property  is  damaged  or  misappropriated  by  employees,
contractors or  representatives  of Ordering  Company,  Ordering  Company is not
responsible  for the  safekeeping of such  property.  When  Supplier's  property
located  on  Ordering  Company's  property  is  damaged  or  misappropriated  by
employees, contractors, or representatives of Ordering Company, Ordering Company
shall be liable to Supplier for such damage or misappropriation.  Supplier shall
not stop,  delay or interfere with Ordering  Company's work schedule without the
prior  approval  of  Ordering  Company.  Supplier  shall  provide  and  maintain
sufficient covering and take any other precautions necessary to protect Ordering
Company's  stock,  equipment  and other  property  from damage due to Supplier's
performance of the work.

                  (b)  Supplier  recognizes  that  the  continuity  of  Ordering
Company's  telecommunications  services is of paramount  importance  to Ordering
Company,  and Supplier  shall at all times exercise  reasonable  care to prevent
damage to  Company's  plant and shall not use any  equipment  or  methods  which
Ordering  Company  has  informed  Supplier,  either in writing  or through  oral
directives at the work site, might endanger or interfere with its service.

                  6.6 EACH PARTY'S RESPONSIBILITY.  Each party shall be entirely
responsible for all persons that it furnishes working in harmony with all others
when  working  on the other  party's  premises  or those of  Ordering  Company's
customers.   Services  performed  by  either  party  or  its  other  vendors  or
contractors shall not interfere with the other party's performance of services.

                  6.7 ASSURANCE OF SUPPLY. (a) AT&T and Supplier
will jointly
conduct regularly scheduled Life Cycle Management reviews for the
purpose of
sharing information concerning current and future Product and
support
requirements in order to permit both parties to make informed
decisions
concerning such matters. AT&T's priority is to assure the ongoing





<PAGE>





growth and service capabilities of the network are satisfied. In order to ensure
the long term  viability  of the  network,  AT&T will have the option to request
sustained manufacturing service for all Products and components that are used in
the network.

                  (b)  Supplier  must  provide  written   notification  to  AT&T
eighteen (18) months in advance of Supplier's intended date of DA of any Product
used in Ordering Company's network,  or to substitute or replace such Product if
Form, Fit or Function is affected. Supplier will provide nine (9) months written
notice with  regard to BCS  Products  not used in Order  Company's  network.  If
Supplier's  vendor  terminates  production  of a Product  and/or  component of a
Product,  Supplier  will use  reasonable  efforts to  provide  the  Products  or
components or secure sources for such Products or components;  provided however,
that  Supplier  reserves  the right to  provide  a  shorter  notice in the event
suppliers  of  a  Product  or  critical  component   terminates   production  or
maintenance  of such items and no other  sources  for such items can be secured.
Within  six  (6)  months  of  notification  of DA,  AT&T  will  provide  written
notification  to Supplier  that it concurs with  Supplier's  decision or that it
intends to negotiate the terms,  conditions and prices under which  availability
shall be  extended,  provided  that  such  Product  and/or  its  components  are
available  to  Supplier.  Unless  otherwise  agreed to, the  framework  for that
agreement  is that  Supplier  will be entitled to recover its costs of providing
continued  availability,  plus a reasonable  profit.  Software DA is governed by
Section 9.20, NOTIFICATION OF DISCONTINUED AVAILABILITY OF SOFTWARE.

                  6.8 PUBLICITY. Each party shall submit to the other a proposed
copy of all advertising  wherein the name,  trademark,  code,  Specification  or
service mark of the other party or its  Affiliates is  mentioned.  Neither party
shall  publish  or use  such  advertising  without  the  other's  prior  written
approval, which consent shall not be unreasonably withheld or delayed.

                  6.9 RIGHT OF  ACCESS/PERMITS  AND APPROVALS.  Each party shall
have the right to enter the premises of the other party during  normal  business
hours with respect to the  performance of this  Agreement,  subject to all plant
rules and regulations,  security  regulations and procedures and U.S. Government
clearance  requirements if applicable.  No charge shall be made for such access.
Reasonable prior notification  shall be given when access is required.  Ordering
Company shall have the responsibility for obtaining all state, local and federal
approvals and permits prior to the  commencement  of the work. Any limitation of
or delay in  providing  timely  access  may  result  in a change  of  Supplier's
schedule for performing  its  obligations  hereunder and  additional  charges to
recover additional expenses incurred by Supplier as a result of such limitations
or delays.

                  6.10 FORCE  MAJEURE.  Neither party shall be held  responsible
for any delay or failure in performance to the extent that such delay or failure
is caused by a Force Majeure; provided, however, that Ordering Company shall not
be  relieved  by reason of such  cause of its  obligation  to make  payments  to
Supplier.  If any Force Majeure condition occurs, the party delayed or unable to
perform shall give prompt  notice to the other party,  stating the nature of the
Force  Majeure  condition  and any action  being taken to avoid or minimize  its
effect.  The  party  affected  by the  other's  delay or  inability  to  perform
(hereinafter the "Affected Party") may elect






<PAGE>





to: (a) suspend the applicable  Supplemental Agreement or Order for the duration
of the Force Majeure condition and (i) only to the extent  reasonably  necessary
to maintain the normal  operation of the Affected Party's  business,  buy, sell,
obtain or furnish  elsewhere  the Product,  Licensed  Material or Services to be
bought,  sold, obtained or furnished  thereunder (unless such sale or furnishing
is prohibited  under this  Agreement,  a Supplemental  Agreement or an Order, in
which event an Ordering  Company  experiencing a Force Majeure  condition  shall
bear Supplier's  reasonable costs (including  inventory costs) incurred awaiting
cessation  of the Force  Majeure  condition)  and, at the option of the Affected
Party,  deduct  from any  commitment  the  quantity  bought,  sold,  obtained or
furnished or for which  commitments  have been made  elsewhere and (ii) once the
Force  Majeure  condition  ceases,   resume  performance  under  the  applicable
Supplemental  Agreement or Order with an option in the Affected  Party to extend
the period of such Supplemental  Agreement or Order up to the length of time the
Force  Majeure  condition  endured  and/or (b) when the delay or  nonperformance
continues for a period of at least thirty (30) days, terminate, at no charge and
without any  liability,  the applicable  Supplemental  Agreement or Order or the
part of it relating to Products or Licensed  Material  not already  shipped,  or
Services not already performed. Unless written notice is given within forty-five
(45) days after the Affected  Party is notified of the Force Majeure  condition,
option (a) shall be deemed selected. Nothing contained herein or elsewhere shall
impose any obligation on either party to settle any labor difficulty.

                  6.11 INDEPENDENT  CONTRACTOR.  All work performed by Supplier,
AT&T or an  Ordering  Company  under this  Agreement  shall be  performed  as an
independent  contractor  and  not as an  agent  of  the  other,  and no  persons
furnished by the performing party shall be considered the employees or agents of
the other.  Each party is wholly  responsible for withholding and payment of all
federal,  state,  and local income and other  payroll  taxes with respect to its
employees, including contributions from them as required by law.

                  6.12 RELEASES  VOID.  Neither party shall require  releases or
waivers of any personal rights from representatives or employees of the other in
connection  with  visits to its  premises,  nor shall  such  parties  plead such
releases or waivers in any action or proceeding.

                  6.13 SURVIVAL OF OBLIGATIONS. The rights and
obligations of
the parties which by their nature would continue beyond the
termination,
cancellation, or expiration of this Agreement, including, but not

MISAPPROPRIATION, INSURANCE,
RELEASES VOID, USE OF INFORMATION, CONTINUING PRODUCT SUPPORT -
PARTS AND
SERVICE, PRODUCT WARRANTY, SOFTWARE WARRANTY, WARRANTY FOR
SERVICES OTHER THAN

survive such
termination, cancellation or expiration.
   

                  6.14 GOVERNMENT  CONTRACT  PROVISIONS.  Ordering Company shall
identify in a request for proposed Supplemental Agreement if a Product, Licensed
Material or Service to be  provided  by  Supplier  is  intended  for use under a
government  contract and if government  contract flowdown provisions shall apply
to such procurement, with identification of such flowdown





<PAGE>




provisions.  In such a case,  Supplier  will  advise  AT&T if it will  submit  a
proposal,  bid or accept an Order on such basis and, if so, it will  address its
acceptance or compliance with the flowdown terms and conditions in its proposal,
bid or Supplemental  Agreement.  Orders placed in accordance with such proposal,
bid or  Supplemental  Agreement  will be  subject to the  identified  government
contract provisions as negotiated.  If an Order or Supplemental  Agreement fails
to specify the  inclusion of  government  flowdown  clauses or is issued by AT&T
without the prior  identification of government contract use or flowdown clauses
as provided  above,  Supplier  shall have the right to  terminate  such Order or
Supplemental  Agreement and collect from Ordering  Company  charges for expenses
incurred until the effective date of such termination.

                  6.15 QUALITY SYSTEM AUDIT. (a) Supplier shall
maintain a
compliant quality system that is subject to third party quality
system audit
that shall include the following elements:

                  (i)      Management Responsibility
                  (ii)     Quality System Principles
                  (iii)    Quality in Marketing
                  (iv)     Quality in Specification/Design
                  (v)      Quality in Procurement
                  (vi)     Quality in Production
                  (vii)    Control of Production
                  (viii)   Product Verification
                  (ix)     Control of Measuring and Test Equipment
                  (x)      Non-conformity
                  (xi)     Corrective Action
                  (xii)    Handling and Post-production
                  (xiii)   Quality Documentation and Records
                  (xiv)    Use of Statistical Methods

                  (b)  Such  an  audit  shall  assess  the   effectiveness   and
documentation  of the  various  elements  that  comprise a  functioning  quality
system.  Supplier agrees that any deficiencies  discovered in Supplier's quality
system as a result of the audit(s)  shall be remedied by Supplier at  Supplier's
expense.

                  6.16 ISO 9000.  Supplier will undertake all reasonable actions
to become ISO 9000  registered.  Certain  vintage  Products are exempt from this
Section. Such registration must be made by a third party registrar(s) accredited
in the  following  countries:  United  States or such  other  country  as may be
designated in writing by AT&T or an Ordering Company.

                  6.17   UTILIZATION  OF  MINORITY  AND   WOMEN-OWNED   BUSINESS
ENTERPRISES.  It  is  AT&T's  policy  that  minority  and  women-owned  business
enterprises  ("MWBE's)  as  defined  in  Exhibit  6-1  shall  have  the  maximum
practicable opportunity to participate in the performance of contracts. Supplier
agrees to use its good faith efforts to utilize  MWBE's to carry out this policy
to the fullest extent consistent with the efficient  performance of its business
and this





<PAGE>




Agreement.  In addition to these general  conditions for MWBE support,  provided
that Ordering  Company will work with Supplier to seek out MWBE's and works with
Supplier in the  development of  opportunities  for the use of MWBE's,  Supplier
agrees  to (a) work with  Ordering  Company  to  develop  opportunities  for the
utilization  of MWBE's  for  first  tier  procurement  of  Supplier's  Products,
Licensed  Materials  and  Services by Ordering  Company,  (b) use its good faith
efforts to utilize MWBE's in support of this Agreement and strive to achieve the
portion of total expenditures for all Products,  Licensed Materials and Services
purchased  from  Supplier  equal  to 5% of  the  value  of  Ordering  Companies'
purchases of Products,  Licensed  Materials  and Services from Supplier in 1996,
and strive to increase such  percentage  by 10% each of the  following  years of
this Agreement and (c) support Ordering  Companies' state and regional goals for
MWBE  and   service-disabled   veterans   spending  in   California   and  other
states/regions  as may be defined in the  future.  Supplier  agrees to conduct a
program which will enable MWBE's to be considered fairly as  subcontractors  and
suppliers under this Agreement.  Supplier shall submit to AT&T periodic  reports
of work with known  MWBE's in the form of Exhibit 6-1 in such manner and at such
time (not more than  quarterly) as AT&T's  representative  may  prescribe.  Such
periodic  reports shall state  separately for MBE's and WBE's the  subcontracted
work which is  attributable  to Ordering  Companies.  In instances  where direct
correlation  cannot be  determined,  such MWBE  payments may be  established  by
Supplier comparing  Ordering Company's payments to Supplier,  in that period, to
total payments to Supplier from all of its customers,  in that period,  and then
arriving at Ordering Company's  apportionment of such MWBE payments.  Nothing in
this clause shall affect or diminish Supplier's  obligations as set forth in the
assignment and subcontracting provisions.

                  6.18 ASSIGNABILITY. Except as provided in this clause, neither
party shall assign this Agreement or any right or interest under this Agreement,
nor delegate any work or  obligation  to be performed  under this  Agreement (an
"assignment")  without the other party's prior  written  consent.  Any attempted
assignment  in  contravention  of this  clause  shall be void  and  ineffective.
Nothing shall  preclude a party from employing a  subcontractor  in carrying out
its obligations under this Agreement; provided, however, that if Supplier uses a
subcontractor  to perform a material service or obligation under this Agreement,
such use will be  subject  to AT&T's  written  consent.  Supplier's  use of such
subcontractor  shall  not  release  Supplier  from its  obligations  under  this
Agreement.  Notwithstanding  the  foregoing,  Supplier  shall  have the right to
assign this Agreement and to assign its rights under this Agreement, in whole or
in part,  to any present or future  Affiliate or to any entity  which  purchases
from  Supplier  the  operating  asset(s)  utilized  by  Supplier  to fulfill its
obligations  hereunder,  subject to AT&T's written consent,  which consent shall
not be unreasonably withheld; provided, however, that in any such event Supplier
shall not be released from its obligations hereunder and shall indemnify, defend
and hold  harmless each  Ordering  Company for all losses or damages  arising in
connection  therewith,  including  from any  breach  of this  Agreement  by such
assignee.  The notice of  assignment  shall state the  effective  date  thereof.
Following the effective date and to the extent of the assignment, Supplier shall
not be released from obligations.  For purposes of this clause,  the "Agreement"
includes this Agreement,  each Supplemental Agreement,  each Order and any other
subordinate agreement placed under this Agreement.

GOVERNING ARBITRATION PROCEDURES,  this Agreement and, unless expressly provided
therein,  each  Supplemental  Agreement,  shall be governed by and construed and

expense with applicable laws, ordinances, regulations, codes, rules, guidelines,
orders,  permits and  approvals of any  governmental  body,  including,  but not
limited to, those relating to the environment,  health,  and safety.  Each Party
agrees to indemnify, defend (at the other party's request) and save harmless the
other party, its Affiliates, its and their customers and each of their officers,
directors and employees from and against any losses,  damages,  claims, demands,
suits,   liabilities,   fines,  penalties  and  expenses  (including  reasonable
attorney's  fees) that arise out of or result  from (i) failure to do so or (ii)
activity,  duty  or  status  of such  party  that  triggers  any  obligation  to
investigate or remediate environmental contamination.

                  6.21 RECORD  RETENTION.  Ordering  Company
agrees to keep true
and accurate  records with regard to its use of  Supplier's
Licensed  Material.
Supplier  shall have the right to inspect such records at any  reasonable  time,
not more often than once each calendar year, upon  reasonable  notice in writing
to Ordering Company. Supplier shall bear the cost of such auditing.

                  6.22  NON-WAIVERS.  The failure of either party at any time to
enforce any right or remedy  available  to it under this  Agreement or otherwise
with  respect to any breach or failure by the other party shall not be construed
to be a waiver  of such  right or remedy  with  respect  to any other  breach or
failure by the other party.

                  6.23 THIRD PARTY  BENEFICIARIES.  Except as otherwise provided

of  substitute
         components  of Ordering  Company's  selection  and not

days  after  (aa)
         installation  completion  of a Product,  if Supplier has
installed the
         Product or (ab) delivery, if Supplier is not installing
the Product, if
         Ordering  Company  notifies  Supplier of a defect or
nonconformity  of
         Products  to the  Specifications,  that does not  appear
to be  curable
         through repair or replacement within a reasonable time
period, Ordering
         Company will be entitled,  at its option,  to a refund of
the Product's
         purchase price and  installation  charges and the
associated  Licensed
         Materials charges.  Should Ordering Company seek such a
refund, it will
         provide  Supplier such  cooperation as necessary to
enable  Supplier to
         remove the Product from Ordering Company's premises,  if
necessary.  In
         the event of such refund,  Ordering  Company may also
return for credit
         any other  Products  intended for use with the
defective  Product that
         cannot be applied to another  use by  Ordering  Company
and may cancel,
         without liability for cancellation charges, any pending
Orders for such
         Product.

                           (ii)  After  sixty  (60) days from
(aa)  installation
         completion of a Product,  if Supplier has installed the
Product or (ab)
         delivery,  if Supplier is not installing the Product,
with respect to a
         defect or  nonconformity  of  Products  to  Supplier's
Specifications,
         Supplier shall take the following action promptly:

                                    (A) Supplier, at its option,
shall attempt
         first to repair or  replace  such  Product  without
charge  or, if not
         feasible,  provide a refund or credit  based on the
original  purchase
         price,  installation  charges paid by Ordering  Company
if installed by
         Supplier,  and the  associated  Licensed  Materials
charges.  Ordering
         Company  must return  Product to Supplier  for repair
and  replacement,
         except as noted in  Sections  8.2 (c) (ii) (B) and (C).
In the event of
         such  refund,  Ordering  Company  may also  return for
credit any other
         Products  intended  for use with the  defective  Product
that cannot be
         applied to another  use by Ordering  Company  and may
cancel,  without
         liability  for  cancellation  charges,  any  pending
Orders  for  such
         Product.

                                    (B) Supplier, in the case of
any service
         affecting  defect,  shall  either (1) repair  such
defect in the field
         using best reasonable efforts to avoid any service
interruption; or (2)
         immediately  replace  the  defective  Product,  Licensed
Material,  or
         Service with a working replacement, at Supplier's
expense, for the time
         that it takes the original Product, Licensed Material, or
Service to be
         repaired.  At Ordering Company's option,  Ordering
Company may elect to
         retain  the  replacement  Product,  Licensed  Material,
or  Service if
         substitution of the original after repair could cause a
further service
         interruption. Where Supplier has elected to repair or
replace a Product
         (other than Cable and Wire  Products)  which has not
been  installed by
         Supplier  and  Supplier  ascertains  that the  Product
is not  readily
         returnable  by Ordering  Company,  Supplier  will repair
or replace the
         Product at Ordering  Company's  site.  For the purposes
of Sections 8.2
         (c) (ii) (B) and (C) and Section 8.2 (d), Cable and Wire
Products shall

interbay cable,
         closures, arrays, and mounts.

                                    (C) With respect to Cable and
Wire Products
         which Supplier has ascertained  are not readily
returnable for repair,
         whether or not installed by Supplier,  Supplier may elect
to repair the
         Cable and Wire Products at Ordering Company's site.

                  (d) If  Supplier  has elected to repair or replace a defective
Product,  Ordering  Company is  responsible  for removing and  reinstalling  the
Product and, in addition,  for on-site  repair or  replacement of cable and wire
products,  Ordering  Company  must make the  Product  accessible  for  repair or
replacement, and is responsible to restore the site.

                  (e)  Products  returned  for  repair  or  replacement  will be
accepted by Supplier only in accordance with its instructions and procedures for
such returns. The transportation  expense associated with returning such Product
to Supplier shall be borne by Ordering  Company.  Supplier shall pay the cost of
transportation   of  the  repaired  or  replacing  Product  to  the  destination
designated by Ordering  Company.  The same Product or part shall not be returned
by Supplier to Ordering Company with the notation no-trouble-found (NTF) on more
than two (2)  occasions.  On the third  occasion that a Product or part has been
classified by Supplier as NTF, the Product or part shall be returned to Supplier
and shall become Supplier's property. Supplier shall ship a new, refurbished, or
reconditioned  replacement to Ordering  Company for the returned Product or part
at no charge for that  Product  under  warranty.  For out of  warranty  Product,
Supplier shall ship a new, refurbished, or reconditioned replacement to Ordering
Company for the returned Product or part at Supplier's  current negotiated price
for the production equipment element/component.

                  (f) The defective or nonconforming Products or parts which are
replaced  shall  become  Supplier's  property.  Supplier  may  use  either  new,
remanufactured,  reconditioned, refurbished, or functionally equivalent Products
or parts in the  furnishing  of repairs or  replacements  under this  Agreement.
Unless otherwise agreed or unless unavailable, Supplier shall use new components
in the repair of Products.

                  (g) If a Product for which warranty  Service is claimed is not
defective or is in conformance,  Ordering  Company shall pay Supplier's costs of
handling, inspecting, testing, and transporting, and, if applicable,  reasonable
traveling and related expenses as referenced in Section 3.1 (g), PRICES.

                  (h)  Supplier  makes no  warranty  with  respect to  defective
conditions or  nonconformities  resulting from the following:  Ordering  Company
modifications,  misuse, neglect,  accident or abuse, improper wiring, repairing,
splicing,  alteration,  installation,  storage  or  maintenance  other  than  by
Supplier,  use in a  manner  not  in  accordance  with  Supplier's  or  vendor's
Specifications or operating instructions or failure of Ordering Company to apply
previously   applicable  Supplier   modifications  and  corrections  which  were
available  without extra charges and which  Ordering  Company had had reasonable
opportunity  to apply.  In addition,  Supplier makes no warranty with respect to
Products  which have had their serial  numbers or month and year of  manufacture

manufacturing  (i.e. any custom or legacy products  requiring unique procedures,
such as NGLN, DDM1000,  FT-Series G and projects such as Customer Connectivity).
Special Product or unique arrangements will require a Supplemental  Agreement to
document the agreements made specifically for that Product or project only.

                  (b) Supplier and Ordering  Company shall identify  Products or
technologies that will require special arrangements and for which Supplemental
Agreements must be negotiated.

                  (c)  Ordering  Company  will  provide to Supplier on a monthly
basis via the Customer Demand Planning (CDP)  mechanized  system,  a forecast of

encompass all of the network Product requirements for Ordering Companies.





<PAGE>



                  (e) Orders will be placed within Supplier's  planning interval
documented in Exhibit 2-1, Planning Intervals,  to the extent possible, and will
constitute  a  commitment  to buy.  Ordering  Company  will  compare the monthly
forecast with the  semi-annual  planning  forecast  being  provided in April and
September,  and  will  reconcile  the two  accordingly.  In the  future,  if the
frequency of these forecasts changes, a similar reconciliation will be performed
on all Product  elements that are provided in the planning  forecasts.  Ordering
Company  and  Supplier  will  review  Ordering  Company's  forecasting  accuracy
quarterly with the goal of obtaining 80% forecasting accuracy.  Ordering Company
will work with Supplier to provide Product level requirements on a monthly basis
especially  for those  forecasts  within the six (6) month window as part of the
rolling forecast.

                  (f) CUSTOMER DEMAND PLANNING  (CDP).  Should Ordering  Company
request a programming change to the CDP system that would benefit external users
of the CDP system,  Supplier shall make such modification at no cost to Ordering

that is specific to Ordering  Company's needs,  such  modification to the system
shall be made at a cost mutually  agreed upon by Ordering  Company and Supplier.
Supplier  shall  provide  Ordering  Company  with  CDP  system  support  via the
1-800-CDP-8845 Hotline at no cost to Ordering Company.

                  (g) METRICS.  Ordering  Company and Supplier  agree to monitor
forecast accuracy on a monthly basis.  Forecast accuracy  measurements  shall be
based  upon a two month  lead time for each  forecasted  item.  CDP shall be the
vehicle  for  gathering  data on forecast  accuracy  and  shipping  performance.
Ordering Company will monitor its forecasts and seek to achieve  improvements in
accuracy as described in Exhibit 8-3.  Supplier will monitor and seek to achieve
improvements on performance to customer  requested  completion date (CRCD),  and
performance to published order  intervals.  This is an informal process and does
not imply  penalty for  non-performance.  The 1996 metric goals are set forth in
Exhibit  8-3.  Joint  goals  and  metrics  for  future  years  will be  mutually
negotiated for continuous improvement.

                  (h)  FORECASTING  PROCESS   MONITORING.
Forecasting  Process
Performance  Goals  will be  monitored  on an  ongoing  basis  by the  Inventory
Management Process Management Team and the Forecasting Quality
Improvement Team.
Additional  meetings to review forecasting  specifics may be scheduled as needed
by either Ordering Company or Supplier.

                                    (A) Database Problems - If the
condition is
         mutually  determined  to be the result of  corruption  of
the  Software
         Product data base, and such  corruption is not the direct
result of the
         Product,  the condition  will be referred back to
Ordering  Company for

Supplier's option,
         Supplier  may  prepare a proposal  for  billable
corrective  action to

corruption is the
         result of, or caused by another of  Supplier's  Products
or  Services,
         Supplier shall initiate Problem  Management  regardless
of whether such

arrangements  Ordering
         Company may have for such hardware or Firmware.

         condition is determined mutually to be caused by systems
other than the
         Products covered under the existing Order,  including,
but not limited
         to,  systems which  interface  with the Product,  the
condition will be
         referred to Ordering  Company for  corrective  action
unless such other
         system has been  furnished by Supplier,  in which case,
Supplier shall
         initiate Problem  Management.  However,  if a defect is
identified with
         Software  or  Products  covered  by the Order  which is
documented  or
         advertised to interface or work with other systems,
hardware,  Products
         or Software,  Supplier shall conduct restoral and

Additional
         services,  including  but not  limited to custom

provided by Ordering  Company.  If the Services prove to be not so performed and
if Ordering  Company notifies  Supplier,  within the period of time equal to the
repaired  Product  warranty period (Exhibit 8-1), of the Product being repaired,
or six (6) months,  whichever is less,  commencing  on the date of Acceptance of
the Service,  as  identified in writing by Supplier,  Supplier,  at it's option,
either will correct the defect or  nonconforming  Service for which  Supplier is
responsible or render a full or prorated  refund or credit based on the original
charge for the Services.  After the corrective  action,  Ordering  Company shall
have the right to Acceptance of the corrective work done.

Company;  or, (b) license Ordering Company to reproduce  Supplier's  copyrighted
training modules or manuals, covering those areas of interest outlined in (a) of
this  clause,  sufficient  in detail and format,  to allow  Ordering  Company to

         otherwise   provided   in   Section   11.18,
ARCHAEOLOGICAL   SITES;
         ENVIRONMENTAL  PROTECTION,  Ordering  Company  shall
provide,  or,  at
         Ordering  Company's option,  shall authorize  Supplier to
provide,  any
         consultants for special considerations,  including, but
not limited to,
         biologists to evaluate  endangered species impacts or
archaeologists to
         evaluate historically sensitive sites and qualified
experts to evaluate
         environmentally  hazardous  conditions.  In  the  event
that  Supplier
         provides such  consultants,  Ordering Company shall
reimburse  Supplier
         for such consultant costs on a Lump Sum Price basis; and

                           (ii) EASEMENTS,  PERMITS,  AND RIGHTS
OF WAY - Unless
         otherwise  required by applicable  ordinances,  codes or
statutes,  any
         necessary highway permits,  construction permits,

         or  right of way  grants  shall be  obtained  and paid
for by  Ordering
         Company and Ordering  Company shall file, or have filed,
the necessary
         papers (collectively, the "Ordering Company Permits").
Ordering Company
         Permits  and  corresponding  permit  applications,  if
necessary,  are
         included in the Agreement Documents.  If a permit is
unavailable at the
         time of issue of the Agreement  Documents,  the permit
application only
         will appear.  Permits  which are not  available at the
time of issue of
         the Agreement Documents will be provided to Supplier
prior to the Start
         Date  specified  in each Work  Order.  When  permits  not
listed in the
         Agreement  Documents are obtained by Ordering  Company,
a copy will be
         provided to Supplier.

                           (iii) Railroad flagmen and/or
inspectors  required to
         be on the Site as a condition of an easement  permit or
right of way or
         other railroad requirement,  will be provided by Ordering
Company at no
         cost to Supplier.

                  11.5 WORK ORDERS;  CHANGES.  (a) Ordering Company shall submit
Work Orders to Supplier  utilizing  Ordering Company's form. Each Work Order and
Field  Order shall  contain or refer to a document  containing  the  information
necessary for Supplier to fulfill the Work Order, including, but not limited to,
the information  called for by Section 2.1,  ORDERS,  above, a reference to this
Agreement,  Special Conditions,  a Start Date,  Completion Date and a Completion
Schedule.  If such work items have been mutually agreed upon in a writing signed
by the parties  (e.g.,  a  Supplemental  Agreement or a  previously  issued Work
Order),  then Supplier  shall proceed to fulfill the Work Order (i.e.,  the Work
Order shall  function as a notice by  Ordering  Company for  Supplier to proceed
with the Work). If such items have not been agreed upon, Supplier may reject the
Work Order or propose  changes to the Work  Order.  If the parties are unable to
agree, the Work Order shall be deemed abandoned.


<PAGE>



                  (b) Each Work  Order and Field  Order  shall be subject to the
terms and conditions of this Agreement  which shall control over any conflicting
provisions in such Work Order.

                  (c)  Changes by  Ordering  Company to an  accepted  Work Order
shall be treated as a separate  Work Order  unless the parties  expressly  agree
otherwise.  In  addition,  subject  to  Section  11.18,   ARCHAEOLOGICAL  SITES;
ENVIRONMENTAL  PROTECTION,  Supplier may identify additional changes to the Work
which must be performed due to certain conditions, as set forth in Section 11.8,
LOCAL  CONDITIONS;  DIFFERING SITE CONDITIONS  below. If any such change affects
Supplier's  ability to meet its obligations  under the original Work Order,  any
Price or  Completion  Date quoted by Supplier with respect to such original Work
Order is subject to change.  All such  changes  must be  approved  in writing by
authorized representatives of both parties using Ordering Company's Form.

                  (d) Minor changes may be made by means of a
Field Order.

                  11.6 PLANT PROTECTION; UNDERGROUND FACILITIES.
(a) Supplier
shall adhere to the applicable MOP with respect to Ordering
Company's
underground facilities.

                  (b)  Ordering  Company  has made  minimal  efforts to identify
existing  utilities  by field  surveys and utility  records  research.  Existing
underground and aerial utilities within the construction  limits of the Work are
indicated on the Drawings only to the extent  information  on such utilities has
been made available to, or discovered by, the Engineer in the performance of the
design  work.  Except to the  extent  that the  information  contains a material
misrepresentation  of fact, the Engineer and Ordering Company expressly disclaim
all  responsibility  for  the  accuracy  and  completeness  of  the  information
indicated.  Supplier shall conduct its operations on the basis that  underground
and aerial utilities may exist which are not indicated on the Drawings.

                  (c)   Supplier   shall  be   responsible   for   locating  and
identifying,  except  for  Ordering  Company's  facilities  or  structures,  all
existing  utilities or  structures  within the  construction  limits of Work and
elsewhere where Supplier's  construction operations may subject the utilities or
structures to damage.  This shall be done prior to the  performance of the Work.
All information  relative to the above shall be recorded and  incorporated  into
the records in a manner reasonably acceptable by the Engineer.

                  (d) For Ordering  Company  facilities or structures,  Supplier
shall adhere to the "One Call" procedure, as set forth in the Specifications.

                  11.7 PROTECTION OF PUBLIC AND PUBLIC PROPERTY.
Subject to any
more stringent requirements of Section 11.18, ARCHAEOLOGICAL SITES;
ENVIRONMENTAL PROTECTION, and Section 6.20, COMPLIANCE WITH LAW:

                  (a) Supplier  shall in the  performance  of the Work  exercise
reasonable  measures to minimize  inconvenience  to the public and shall use its
reasonable efforts to preserve and protect


<PAGE>



all trees, shrubs, grass, or other vegetation on or adjacent to the right of way
or Site which do not  unreasonably  interfere  with the Work.  Unless  otherwise
required by Ordering Company's  Representative,  Supplier shall restore all such
property  which may be  disturbed  in the  execution  of its Work to its  former
visible condition.

                  (b) In accordance with  Supplier's  standard  procedures,  all
pavement,  surfacing,  driveways,  curbs, walks,  buildings,  utility poles, guy
wires,  fences,  and other  surface  structures  affected  by  Supplier's  Work,
together  with  all  sod and  shrubs  in  yards  and  parking  areas,  shall  be
substantially  restored to their original visible  condition,  whether within or
outside the easement.  Supplier shall be responsible  for (i) making  reasonably
satisfactory  and  acceptable  arrangements  with the owner of, or the agency or
authority having  jurisdiction over, the damaged property  concerning its repair
or (ii) replacement,  or payment of reasonable costs incurred in connection with
such damage caused by Supplier or its Subcontractors.

                  11.8 LOCAL  CONDITIONS;  DIFFERING SITE  CONDITIONS.  (a) Upon
execution of a Work Order,  Supplier admits to being  reasonably  informed as to
the nature and locations of the Work set forth therein; provided,  however, that
in all cases,  except as  otherwise  provided in Section  11.18,  ARCHAEOLOGICAL
SITES;  ENVIRONMENTAL  PROTECTION,  Differing Site Conditions shall be the basis
for a Change  Order  and  additional  compensation  as set  forth  below in this
Section 11.8.

                  (b) Delays,  Additional  Work,  or extra costs may result from
Differing Site Conditions of which neither  Ordering Company nor Supplier should
reasonably  have had knowledge at the time of the effective  date of the earlier
of the  Supplemental  Agreement,  the Work Order and the Change  Order.  In such
case:

                           (i) Supplier  shall,  promptly  and
before  Differing
         Site Conditions are disturbed,  notify the Engineer in
writing by means
         of the Ordering Company Change Order Form of such
conditions;

                           (ii)  After  receiving  notice  from
Supplier,   the
         Engineer shall promptly investigate the Differing Site
Conditions, and,
         if in his reasonable  judgment,  such  conditions
exist,  the Ordering
         Company  Representative  shall  by  means  of a  Change
Order  make an
         equitable  adjustment  to the Price  and the  Completion
Schedule,  as
         agreed by Supplier; and

                           (iii)  No  claim  of   Supplier   for
an   equitable
         adjustment because of Differing Site Conditions shall be
allowed unless
         written notice has been given as required.

                  11.9 OUTSIDE PLANT SERVICES SCHEDULING. Prior to
the
pre-construction meeting, Supplier shall submit a detailed Outside
Plant
Services Scheduling schedule as set forth in the Specifications.
The Engineer,
Supplier and Ordering Company Representative shall hold


<PAGE>



weekly  status  meetings  at mutually  agreed upon times and
places.  Additional
coordination between the parties will be held on an as needed
basis as set forth
in the Specifications.

                  11.10  INSPECTION AND CORRECTION OF DEFECTS;  ACCEPTANCE.  (a)
Ordering Company's  Representative  shall have free access to the Work performed
and  materials  furnished by Supplier  under this  Agreement  for the purpose of
inspection thereof. Prior to the commencement of the Warranty Period (as defined
in Section  11.12,  WARRANTY,  below),  Supplier  shall upon  receipt of written
request from Ordering  Company's  Representative,  furnish  sufficient labor and
facilities  at  Supplier's  expense,  to make  an  inspection  of  Work  already
completed by uncovering and exposing the Work for inspection.

                  (b) If the  inspection  discloses  that  the  Work  reasonably
conforms to the applicable  Specifications in all material respects, the cost to
Supplier  of (i)  uncovering  and  exposing  the Work,  and (ii)  examining  and
restoring  of the Work shall be  considered a Change Order and shall be paid for
by Ordering  Company.  In addition,  if  completion of the Work has been delayed
thereby, Supplier shall be granted a suitable extension of time and/or delay and
disruption  compensation,   as  mutually  determined  by  Ordering  Company  and
Supplier.

                  (c) If the inspection discloses that the Work does not conform
to the applicable  Specifications in all material  respects,  Supplier shall not
have a basis for a Change Order and shall correct the Work at
its own expense.
The  Completion  Date shall not be extended  because of any delay caused by such
non-conforming Work.

                  (d) If  Ordering  Company  notifies  Supplier  of a defect  or
non-conformance  during the progress of the Work or prior to Final Acceptance or
Beneficial  Occupancy,  Supplier will schedule the repair or replacement of such
Work within two (2) work days after receipt of written notice.

                  (e)  Supplier  may  submit  to  Ordering  Company  a notice of
completion,  placing  Ordering  Company on notice that the Work is complete  and
ready for inspection. Ordering Company shall inspect the Work promptly and in no
event later than seven (7) business  days after  receipt of such notice.  In the
event that  Ordering  Company does not inspect the Work within such time period,
Final  Acceptance shall be deemed to have occurred with respect to such Work. If
the inspection  results in a Punch List,  Final  Acceptance shall occur when the
Punch List is complete to Ordering  Company's  reasonable  satisfaction.  Again,
Supplier may submit a notice of completion regarding the Punch List and the same
procedure set forth above shall apply (i.e.,  Ordering Company shall inspect the
Work no later than seven (7)  business  days  after  receipt of such  notice and
Final  Acceptance  shall be deemed if Ordering  Company fails to inspect  within
that time).

                  11.11 SUPERVISION; CONTROL OF WORK. (a) Supplier
shall keep on
the Work site a competent Superintendent and any necessary
assistants and all of
them shall be reasonably satisfactory to Ordering Company's
Representative.


<PAGE>



                  (b) Supplier  shall have full control and  direction  (i) over
the mode and manner of doing the Work, subject to Sections 6.20, COMPLIANCE WITH
LAWS, and 11.18,  ARCHAEOLOGICAL SITES;  ENVIRONMENTAL PROTECTION,  and MOPS and
(ii) of its personnel employed on or about the Work.

                  11.12 WARRANTY.

                  (a) FOR  PRODUCTS.  The  Warranty for Products
is set forth in
         Section 8.2, WARRANTY; the Warranty Period is set forth
in Exhibit 8-1,
         provided , however,  that the Warranty  Period begins on
the earlier of
         Final Acceptance of a completed Work Order or Beneficial
Occupancy.

                  (b) FOR SERVICES.  The warranty  shall begin on the earlier of
Final  Acceptance of a completed  Work Order or  Beneficial  Occupancy and shall
extend for one (1) year (the "Warranty Period"). Supplier agrees to perform Work
in a professional manner;  using competent and responsible  personnel trained as
required by the most stringent of accepted industry practice, Supplier practice,
Section 6.20  COMPLIANCE WITH LAWS, and Applicable  EH&S  Requirements  (Section
11.18 (c));  and in  accordance  with the  Specifications  or other  agreed upon
specifications  and in accordance  with  accepted  practices in the community in
which the Work is performed  using  material free from defects except where such
material is provided by Ordering  Company.  If Work provided by Supplier  proves
not to have been so  performed,  and if Ordering  Company  notifies  Supplier in
writing to that effect within the Warranty  Period,  then Supplier shall, at its
option, correct any defects or render a full pro-rated refund or credit based on
the original charges for the Work.

                  (c) If the refund or option is not  chosen and if,  during the
Warranty Period,  Ordering  Company notifies  Supplier of a defect covered under
paragraphs (a) and (b) above,  then Supplier shall commence to repair or replace
such Work within seven (7) days after receipt of written notice. Notwithstanding
the above, if the refund or credit option is not chosen and if Ordering  Company
notifies  Supplier  that the defective or  non-conforming  Work is of a critical
nature for network protection or for safety reasons,  Supplier shall commence to
repair or  replace  the Work  within  twenty-four  (24) hours  after  receipt of
written notice.

                  (d) The warranties provided in this Section 11.12 do not cover
repair for damages,  malfunctions or service  failures caused by: (i) actions of
any personnel not employed,  directly or indirectly,  by Supplier; (ii) Ordering
Company's  failure to follow Supplier's  installation,  maintenance or operation
instructions; or (iii) a condition of Force Majeure.

                  (e) THE WARRANTIES  STATED IN THIS SECTION 11.12
ARE EXCLUSIVE
AND ARE IN LIEU OF ALL OTHER EXPRESSED OR IMPLIED WARRANTIES,
INCLUDING BUT NOT
LIMITED TO WARRANTIES OF  MERCHANTABILITY  OR FITNESS FOR A
PARTICULAR  PURPOSE.
EXCEPT FOR (a) TANGIBLE  PROPERTY  DAMAGE AND PERSONAL INJURY FOR
WHICH SUPPLIER
IS HELD LIABLE AND (b) THE REMEDY PROVIDED IN SECTION 5.1(e),
ORDERING


<PAGE>



COMPANIES' REMEDIES, ORDERING COMPANY'S SOLE AND EXCLUSIVE REMEDY
SHALL BE
SUPPLIER'S OBLIGATION TO REPAIR, REPLACE, MAKE CORRECTIONS OR
REFUND AS SET
FORTH ABOVE IN THIS WARRANTY.

                  (f) PRODUCT RELOCATION OR MODIFICATION. Ordering Company shall
advise  Supplier  promptly  of any change in  location  or  modification  to any
Product  covered by warranty  service under this Agreement.  If such change,  in
Supplier's opinion, creates a safety hazard or is likely to cause a malfunction,
Supplier  may at  Ordering  Company's  expense,  correct the  condition.  If the
condition cannot be corrected to Supplier's  reasonable  satisfaction,  Supplier
reserves the right to terminate  without  liability  warranty service under this
Agreement for the products relocated and/or modified.

                  11.13 SAFETY; EMERGENCY. (a) Supplier shall be
responsible for
the safety of the Work it performs; provided, however, that
Supplier shall not
be responsible for any unsafe circumstance caused by Ordering
Company or Others.

                  (b) Whenever, in the reasonable opinion of Ordering Company or
the Engineer,  Supplier has not taken  sufficient  precautions for the safety of
the public or the protection of the Work or adjacent structures or property, and
whenever,  in the  reasonable  opinion of Ordering  Company or the Engineer,  an
emergency has arisen and immediate action is considered necessary, then Ordering
Company,  with prior  notice to Supplier,  may provide  suitable  protection  by
causing Work to be done and material to be furnished  and placed.  To the extent
that Supplier is responsible  for such emergency,  the reasonable  out-of-pocket
cost of such Work and material  shall be borne by  Supplier,  and if the same is
not paid on presentation of the bills therefor,  such costs may be deducted from
amounts due or to become due Supplier.  The  performance  of such emergency Work
shall not relieve Supplier to the extent of its  responsibility for damage which
may  occur.  Ordering  Company  shall make a good  faith  effort to contact  and
utilize the  services of Supplier to correct the  emergency  protection  problem
prior to retaining the services of another contractor.

                  11.14  ENGINEER'S  DRAWINGS AND
SPECIFICATIONS.  (a) Supplier
will be furnished a sufficient  number of sets of Drawings
including  revisions
thereto and sufficient copies of the Specifications without
charge. All Drawings
and  Specifications  shall be returned to the Engineer  upon
completion  of the
Work.   Supplier   may  retain   sufficient   copies  to  perform
its  Warranty
administration.

                  (b) The Drawings shall be signed by Ordering
Company's
Representative and by Supplier.

                  (c) Supplier shall conduct a normal and customary check of all
dimensions,  elevations,  and  quantities  indicated  on the  Drawings and lists
furnished by the  Engineer.  If  Suppliers  discovers in the course of its work,
major discrepancies  between the Drawings and the conditions at the site, errors
or omissions in the Drawings,  and in the layout as given by stakes,  points, or
instructions,  Supplier shall notify the Engineer.  Supplier will not be allowed
to take


<PAGE>



advantage of errors or omissions in the Drawings or other  Agreement  Documents.
Full  instructions  will be  furnished  by the  Engineer  should  such  error or
omission be  discovered,  and Supplier shall carry out such  instructions  as if
originally   specified;   provided,   however,  that  in  the  event  that  such
instructions  result in an increase  in  Supplier's  costs or in a  Construction
Delay (as defined in Section 11.20, CONSTRUCTION DELAY, below) in the Completion
Schedule,  Supplier  shall  be  entitled  to  reasonable  compensation  and,  if
necessary, an extension in the Completion Schedule.

                  11.15 REFERENCE  STANDARDS.  Reference to the standards of any
technical society,  organization,  or association, or to codes of local or state
authorities,  or AT&T EH&S  Practices  shall  mean the  latest  standard,  code,
Specification,  or tentative standard adopted and published, unless specifically
stated otherwise.  Since the Agreement will likely cover multiple years,  except
as otherwise  required by Section 6.20,  COMPLIANCE  WITH LAW,  Supplier will be
given  sufficient  time to assess and comply with new standards,  and to request
additional time and/or compensation for compliance.

                  11.16  RECORDS.   Supplier  shall  maintain  complete  records
including, but not limited to all labor and equipment hours, material purchased,
and Work  subcontracted  to other  parties.  The records  shall be maintained in
accordance with recognized  commercial  accounting  practices and in such manner
that  they  may be  readily  audited.  The  records,  including  all  supporting
documents,  shall be  available  at all  reasonable  times for audit by Ordering
Company both during the contract  period and for one year  following the date of
final  payment or until all  disputes,  if any,  between  Supplier  and Ordering
Company have been finally  resolved,  whichever  is later.  Supplier  shall also
maintain  weekly sheets,  showing all labor and equipment  employed and material
received.

                  (a)  Supplier  shall  maintain at the site where Work is being
performed or Supplier's  local  construction  office a file of current copies of
all Drawings,  Specifications,  and other Agreement  Documents and supplementary
data.

                  (b) Supplier shall create a timed and dated  pictorial  record
of the Site,  including  paths of ingress and  egress,  before and after Work is
performed for the purpose of precluding or settling claims.

                  11.17 UNFAVORABLE CONSTRUCTION CONDITIONS.  (a) During periods
of unfavorable weather, wet or frozen grounds, or other unsuitable  construction
conditions,  Supplier  shall  confine its  operations  to Work which will not be
affected  adversely  thereby.  No portion of the Work shall be constructed under
conditions  which  would  adversely  affect the quality or  efficiency  thereof,
unless special means or precautions are taken by Supplier to perform the Work in
a proper and satisfactory manner.

                  (b) If adverse weather  conditions are encountered by Supplier
or its subcontractor(s) which are abnormal for the location and time of year for
which such claim is made,  the  construction  schedule  shall be  extended by an
amount of time equal to the effect of


<PAGE>



such adverse weather. If adverse weather is the basis of a claim by Supplier for
additional  time,  such claim shall be  documented  by Supplier and include data
substantiating  that weather  conditions were abnormal for the period of time in
question and Supplier could not have been  reasonably  anticipated  such adverse
weather  and  that  such  weather  conditions  had  an  adverse  effect  on  the
construction schedule.

                  11.18 ARCHAEOLOGICAL SITES; ENVIRONMENTAL
PROTECTION. (a)
Known archaeological, historical or cultural sites along the route
will be
indicated on the Drawings by the Engineer.

                  (b) If  archaeological,  historical or cultural  artifacts are
encountered during construction  anywhere along the route,  construction at that
location shall stop and the Engineer shall be promptly notified.  Supplier shall
not harm or disturb  such  artifacts  until  instructed  by Ordering  Company or
Engineer as to how to proceed. If an extended delay is anticipated, Supplier may
elect to move to  another  location  of Work.  Notwithstanding  anything  to the
contrary herein,  Demobilization and Remobilization or construction delay due to
unanticipated  archaeological  findings  shall  be a basis  for  extra  payment.
Ordering  Company shall be  responsible  for obtaining any necessary  permits in
order to continue Work in the affected area.

                  (c) Ordering  Company  shall  provide  Supplier with AT&T EH&S
Practices, including updates. At the end of each calendar year, Ordering Company
shall provide  Supplier a list of all AT&T EH&S Practices still in effect.  AT&T
EH&S  Practices  shall be deemed  applicable to the Work under a Work Order only
when  provided to  Supplier at or prior to the date of the Work Order.  Supplier
shall  at its  own  expense  comply  with  the  most  stringent  of:  applicable
governmental laws,  regulations,  ordinances,  rules, codes, orders,  guidances,
permits,  approvals;  applicable  easement  or  license  conditions;  applicable
Supplier  EH&S  practices;  and  applicable  AT&T EH&S  Practices  (collectively
"Applicable EH&S Requirements").

                  (d)  Supplier  shall be  deemed  the  generator  of all  waste
associated  with the Work and shall  dispose of that waste at its own expense as
set forth in Section 11.18(c),  ARCHAELOGICAL SITES;  ENVIRONMENTAL  PROTECTION,
above.  "Waste" shall include without limitation all hazardous and non-hazardous
substances  and  materials  associated  with the Work which are  intended  to be
discarded,  scrapped,  or recycled. It shall be presumed that all substances and
materials  associated  with the Work  that  are not  incorporated  into the Work
(including  without   limitation   damaged   components  or  tools,   leftovers,
containers,  garbage, scrap, residues or byproducts),  except for substances and
materials that Supplier or Ordering Company intend to use in their original form
in connection with similar work, are waste.

                  (e) In the event  conditions  are  discovered or created at or
near the site of the Work which may require (i)  investigation or remediation or
(ii)  unforeseen   measures  to  protect  the  environment,   health  or  safety
(collectively  "Adverse EH&S  Conditions"),  the party discovering the condition
shall  immediately  notify the other party. The party in the best position to do
so (or, if the parties are equally  situated,  Supplier)  will then  immediately
take reasonable


<PAGE>



measures  temporarily to contain or otherwise avoid  exacerbation of or exposure
to the  conditions.  Unless Ordering  Company  affirmatively  notifies  Supplier
otherwise,  Supplier  shall also take such  other  actions  as  Applicable  EH&S
Requirements prescribe.

   

                  (f) In the event  Supplier's  failure to comply  with  Section
11.18(c),  ARCHAELOGICAL SITES;  ENVIRONMENTAL  PROTECTION,  above or Supplier's
negligence  or  willful  misconduct  was a not  insignificant  cause  of (i) the
Adverse EH&S  Conditions or (ii)  exacerbation  of the Adverse EH&S  Conditions,
Supplier shall indemnify and hold harmless  Ordering  Company and be responsible
for all costs associated with curing the Adverse EH&S  Conditions.  In all other
events Ordering  Company shall indemnify and hold harmless  Supplier from and be
responsible for all costs  associated  with curing the Adverse EH&S  Conditions.
    

                  11.19  REPORTING  DEFECTS.  (a) If any part of Supplier's Work
depends,  for its proper  execution  or  results,  upon the Work of any  Others,
excepting Subcontractors, Supplier shall inspect and promptly report to Ordering
Company's  Representative  any defects in the Work that render it unsuitable for
the proper execution or results,  and Supplier shall not proceed with that phase
of the Work until so authorized by Ordering Company's  Representative.  Ordering
Company may request and Supplier shall provide such reports in writing.

                  (b)  Supplier  shall be made aware of the  delivery  status of
Ordering Company  furnished  materials and of the progress of construction  Work
being performed under separate  contracts,  in each case as informed by Ordering
Company pursuant to (c) below.

                  (c)  Ordering  Company will  furnish  information  to Supplier
which may be available to it regarding the status of Ordering Company  furnished
materials or construction Work being performed under separate
contracts.

                  11.20 CONSTRUCTION DELAY. (a) Supplier will
complete all Work
on or before the Completion Date unless either Ordering Company
agrees to extend
that Date or Supplier is entitled to an extension pursuant to this
Agreement.

                  (b)  Ordering  Company  will  perform all of its  obligations,
including  provision  of labor and  materials  to be  furnished  by it in such a
manner so as not to delay the  progress of the Work (such being a  "Construction
Delay"),  and in event of its failure to do so, thereby causing loss to Supplier
or as a result of one or more of the  circumstances  set forth in paragraph  (c)
immediately below,  Ordering Company agrees that it will compensate Supplier for
such loss and, if necessary, reschedule the Completion Date to a mutually agreed
upon date. Supplier agrees that if Supplier shall delay the progress of the Work
in breach of its obligations hereunder and such delay causes Ordering Company to
sustain a loss,  then Supplier will  reimburse  Ordering  Company for such loss,
subject to the limitation of Supplier's liability set forth in Article 5 of this
Agreement.

                  (c)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  among the causes of "Construction Delay" for which Supplier shall be
compensated and the Completion  Date shall be rescheduled  pursuant to paragraph
(b) immediately above, are the following:

                           (i) Lack of Ordering Company Permits;

                           (ii) Lack of Ordering Company furnished
material;

                           (iii) Work stoppage by landowner;

                           (iv) Work stoppage by permitting agency
even though
         Supplier has met the requirements of the relevant permits;

                   (v) Railroad company denying access to the
      right-of-way or rail due to railroad's operations which
regulate the
                                Work conditions;

                           (vi) Work stoppage by Ordering Company
to implement
         new requirements, including changes to the Completion
Date or
         Completion Schedule;

                 (vii) Waiting for the presence of the Ordering
                             Company Representative;

                  (viii) Defective or damaged Ordering Company
                               furnished material;

                    (ix) Special Service Precautions per the
         Specifications; and

                 (x) Waiting for Engineer's written approval to
              proceed due to the interference of other contractors.

                  (d) Delay time is payable by Ordering Company for Construction
Delay for the reasons  set forth  above,  when  Supplier  is  prevented  from or
delayed in working on any contracted item that is available
to  Supplier.
Construction  Delay time will begin after Supplier has been denied access to the
Work or Ordering  Company has delayed the Work for an accumulated time in excess
of one (1) hour during a given normal working day.

                  (e) The term  "accumulated  time" shall include  discontinuous
amounts  of time and  shall  be  applied  to an  entire  crew.  For  example,  a
four-person crew that incurred a forty five (45) minute  Construction  Delay due
to a  permit  problem  and  then  later  in the same  working  day  incurred  an
additional Construction Delay for another reason, would begin Construction Delay
time for the crew after fifteen (15) minutes of the second  delay.  If a crew is
into  Construction  Delay  time at the end of a Work day and is  prevented  from
working on any  contracted  item  available  the next Work day and the condition
that caused the Construction  Delay still exists,  then Construction  Delay time
shall continue  without the requirement that it be in excess of one hour for the
second day.


<PAGE>



                  (f) If  Supplier  is forced  to cease all or a portion  of its
operations due to lack of right-of-way, by reason of injunction against Ordering
Company  or  other  legal  obstacles,  or delay  in  Ordering  Company-furnished
material deliveries,  Ordering Company may request that Supplier move to another
site or to move off the project.  At Ordering Company's request,  Supplier shall
move from the portion of the  project  upon which he was  previously  engaged to
another point in the project  designated  by Ordering  Company or to an Ordering
Company  location  completely  off the project.  Supplier  shall at a later date
complete the Work left behind, when requested to do so by Ordering Company,  and
such Work shall be done at prices specified in the Proposal plus  Demobilization
and Remobilization.

                  11.21  NOTICE  OF  LABOR  DISPUTES.   Whenever   Supplier  has
knowledge  that any labor  dispute is delaying or  threatens to delay the timely
performance of the Work, Supplier shall promptly give notice thereof to Ordering
Company.  Supplier  shall  confirm the notice in writing  within  three (3) Work
days.

                  11.22  PERFORMANCE  AND PAYMENT BOND.  Ordering  Company shall
have the right to require  Supplier to furnish a bond for the full and  faithful
performance of the Work and for the payment of all bills,  debts and obligations
related to the Work. The bond shall be in such form,  principal  amount and with
such  sureties as may be required by Ordering  Company.  Ordering  Company shall
reimburse Supplier for the net premium on the bond upon receipt of the sureties'
bills to  Supplier.  Supplier  agrees  and  represents  that no amount  for bond
premium is included in the contract price.

                  11.23 APPLICATION FOR PAYMENT;  TERMS OF PAYMENT. (a) Supplier
shall render to Ordering  Company  Applications  for Payment for an amount based
upon the  quantities  of Work in a Work  Order  which  have  been  completed  by
Supplier during the monthly invoicing period,  unless billing is rendered sooner
pursuant to a written  modification  of this Section or for delay and disruption
compensation  or Special  Conditions  accrued as provided  for  elsewhere in the
Agreement.  Ordering  Company shall promptly approve the Application for Payment
within ten (10)  business  days or notify  Supplier of any disputed  items in an
Application  for Payment.  If at the expiration of such ten business day period,
Supplier does not receive written  approval or rejection from Ordering  Company,
the Application for Payment shall be deemed approved.

                  (b) The method of measurement, basis of payment and conditions
under  which  payments  for  Special  Conditions  are  made  can be found in the
Specifications.

                  (c) For  material  furnished  by  Supplier,  the same terms of
payment  shall apply as the terms which apply for  Services  billed by Supplier.
For Material  supplied by Ordering Company and ordered from Supplier pursuant to
another Article of this General  Purchase  Agreement (e.g., an Order for cable),
the  terms  of  payment  are set  forth in such  Article  or  elsewhere  in this
Agreement.

                  11.24  LIENS.  If as a  result  of  any  act
or  omission  of
Supplier,  any  lien is  filed  by a  Subcontractor  against
Ordering  Company,
Supplier shall cause the same to be discharged of record within  forty-five (45)
days after receipt of written notice thereof from Ordering Company.

                                   ARTICLE XII

prior  employment by such party. In the performance of this Agreement,  Supplier
shall not at any time: (i) misrepresent itself or its status to any third party;
(ii)  provide a false or  deliberately  misleading  reason for  inquiries or the
collection of Information;  (iii) misstate the nature of its  relationship  with

or otherwise  any license or right under any patent,  trademark,  service  mark,

other intellectual  property right which is owned,  controlled by or licensed to

                  (c) The parties'  respective  ownership  interests,  up to and
including one hundred percent (100%),  in and rights to use information  used or
produced by Supplier to perform Consulting Services hereunder,  other than those

Supplemental  Agreement pursuant to which Ordering Company purchases  Consulting
Services from Supplier.

                  12.4 EQUIPMENT  SUPPLIER.  Ordering  Company  warrants that no
current corporate  policy,  would give rise to Supplier or any of its Affiliated
Companies  being  disqualified,  as a  result  of  this  Agreement  or the  work
performed  under it,  from  bidding  upon or being  awarded a contract to supply
telecommunications  or  computer  equipment,  Software,  or related  Services to
Ordering Company.

                  12.5  ORDERING  COMPANY'S   RESPONSIBILITY.

Services  will be  performed in a  professional  manner and in  accordance  with
Ordering Company's  specifications or those referenced in the Order and shall be
in accordance with such  requirements or restrictions as may be lawfully imposed
by governmental  authority.  If the Services prove to be not so performed and if
Ordering Company notifies  Supplier within a thirty (30) day period,  commencing
on the date of completion of the Service, at Ordering Company's option, Supplier
either will correct the nonconforming  Service for which Supplier is responsible
or render a full or prorated  refund or credit based on the original  charge for
the Services.

specific  additional  terms  and  conditions  pursuant  to  which  the  Business
Communications  Systems unit of Supplier  ("BCS")  shall  provide,  and Ordering

applicable Supplemental Agreement,  the Pricing Agreement (LC3775D) or any other
governing  agreement  covering pricing,  except that Sections 1.3 and 1.4 of the
Pricing  Agreement shall govern in any event.  With respect to BCS Products used

                  13.3 ORDERS

                  (a) The term "Order" shall be defined as any Ordering  Company
request to purchase  Products,  to receive a license to use Licensed Material or

Product Agreement,  Service  Agreement,  Purchase/Service  Agreement,  Equipment

                  (b)   Subject   to   Section   2.2,   subsequent   Orders  for
modifications,  additions  or  changes  will  become  an  integral  part of this
Agreement when accepted by BCS.

                  (c) The  Customer  Contract  Return  Date is the date BCS must

                  13.5 BILLING AND PAYMENT

                  (a) This section overrides any inconsistent provisions in Part
1 and covers how BCS will invoice Ordering Company.

                  (b) For Products  that BCS  installs,  BCS will bill  Ordering
Company for the Product and installation charges on the In-Service Date, except
as provided in Section 14.4(b).

                  (c) For Ordering Company-installed  Products,
BCS will invoice

apply.

                  (f) If Ordering  Company  does not  generally  pay in a timely
fashion,  the  parties  agree to review the billing  and  payment  processes  to
improve such processes.

                  13.6 HAZARDOUS  MATERIAL.  Ordering Company is responsible for
removal  of  any  hazardous  material  (e.g.,  asbestos)  or  correction  of any
hazardous condition that affects BCS's performance of Services. Services will be
delayed until Ordering Company removes or corrects any such hazardous  condition
with no penalty to BCS.

                  13.7 IDENTIFICATION CREDENTIALS.  Ordering Company may, at its
discretion, require BCS's employees and subcontractors to exhibit identification
credentials,  which  Ordering  Company  may  issue,  in order to gain  access to
Ordering  Company's premises for the performance of the work. If for any reason,
any of BCS's  employees or  subcontractors  are no longer  performing  work, BCS
shall  immediately  inform Ordering  Company's  Representative  in the speediest
manner  possible.  Notification  shall be  followed  by the prompt  delivery  to
Ordering Company's Representative of the identification  credentials involved or
a written statement of the reasons why the identification  credentials cannot be
returned.  Subject to Section 5.1 of this Agreement, BCS shall be liable for any
damage or loss sustained by Ordering Company if the  identification  credentials
are not returned to Ordering Company.

                                   ARTICLE XIV
                              PURCHASE OF PRODUCTS

                  14.1  GENERAL.  The  provisions  of this  Article  14 shall be
applicable  to the  purchase  of  Products  from BCS.  If Software is also to be
licensed  for  use  on a  purchased  Product,  or if a  Product  is  also  to be
engineered or installed by BCS, the  provisions of Articles 15 and 16 shall also
be applicable.


<PAGE>




                  14.2 CHANGE  CONTROL DATE. The Change Control Date ("CCD") for
Orders,  is a date shown on the Order or confirmation  of the Order,  and is the
last date BCS will be required  to accept  changes to the  Products  ordered for
delivery  on  the  Delivery   Date  for   Customer-installed   Products  or  for
installation on the In-Service Date for BCS-installed  Products.  The CCD is the
date BCS accepts the Order or is deemed to have  accepted it pursuant to Section
2.2, unless a different date is shown on the Order or confirmation of the Order.
Changes to the original  Order received by BCS prior to the CCD must be approved
in writing by authorized  representatives  of both parties.  Changes to an Order
received  and  accepted by BCS after the CCD will be treated as separate  Orders
and may be delivered after the Delivery Date for Customer-installed  Products or
may be installed after the In-Service Date for BCS-installed  Products.  The CCD
for Orders for modifications or additions  addressed in this Section will be the
date BCS accepts the Order or is deemed to have  accepted it pursuant to Section
2.2.

                  14.3 ORDERING COMPANY-INSTALLED PRODUCTS.

                  (a) The "Delivery  Date" is the date BCS
delivers the Products
to the Ordering  Company's  facility as specified in an Order or
confirmation of
Order.

                  (b)  BCS  will  make  reasonable  accommodations  if  Ordering
Company requests a delay in the originally  scheduled  Delivery Date if Ordering
Company  gives BCS written  notice prior to the CCD. If Ordering  Company  gives
notice of a request for a delay in the originally  scheduled delivery date after
the CCD,  requests more than one delay in the Delivery Date prior to the CCD, or
causes a delay in the Delivery Date as a result of Ordering Company's failure to
meet  obligations  under  this  Agreement,  BCS may  cancel  the  Order and bill
Ordering  Company for  cancellation  charges as set forth in Part 1 of this GPA;
provided however, that BCS shall give Ordering Company fifteen (15) days written
notice of its  intention  to cancel the Order and to bill  cancellation  charges
pursuant  to this  Section  and shall not cancel the Order if  Ordering  Company
accepts  delivery  prior to the  expiration of such period.  In addition,  BCS's
notice  shall  include a  reasonable  estimate of the  anticipated  cancellation
charges.  Notwithstanding  the  foregoing  provisions  of this Section  14.3(b),
Ordering  Company  may  delay  delivery  one time for up to  thirty  (30)  days,
provided Ordering Company has given BCS seven (7) business days' notice prior to
the scheduled ship date.

                  (c) Shipping charges may be adjusted if Ordering
Company
changes the location for delivery.

                          14.4 BCS-INSTALLED PRODUCTS.

                  (a) This Section 14.4 overrides any inconsistent
terms in Part
1 of this Agreement.  For all BCS Products,  if BCS installs such
Products,  BCS
will notify Ordering Company that the Product is installed in good
working order
and complies with BCS's  standard  specifications  and any other
specifications
agreed to by the parties (the "In-Service Date"). For


<PAGE>




BCS's DEFINITYPBX and Multimedia Messaging and Response ("MM&R") Products,  such
notice  will be in  writing  and  Ordering  Company  shall  have ten  (10)  days
following the  In-Service  Date (the  "Acceptance  Period") to test the DEFINITY
and/or MM&R Product and to determine  whether  Ordering  Company agrees with BCS
that such Product complies with the applicable specifications and warranties for
that  Product.  If Ordering  Company does not notify BCS in writing  during such
Acceptance   Period  of  any   non-conformities   to  the   applicable   product
specifications  and  warranties,  the Product will be deemed  accepted as of the
In-Service Date.

                  During the  Acceptance  Period,  Ordering  Company may conduct
appropriate tests and then shall either:  (a) accept the Product -- by providing
written  notice to BCS of that fact,  in which case the  Product  will be deemed
accepted  as  of  the  In-Service  Date;  or  (b)  if  non-conformities  to  the
specifications  or warranties  exist, so advise BCS in writing,  specifying such
non-conformities.  BCS shall promptly correct such  non-conformities  and notify
Ordering  Company that they were corrected.  The Product will be deemed accepted
by  Ordering  Company  upon  correction  of the  non-conformities  specified  in
Ordering Company's notice.

                  If  BCS  is  unable  to   correct   all  of  the   significant
non-conformities  described in Ordering Company's notice within thirty (30) days
of receipt of Ordering  Company's  notice,  Ordering  Company shall either:  (a)
accept the  Product,  in which case BCS will be  required to continue to correct
any outstanding  non-conformity;  or (b) Ordering Company may reject the Product
without  any  liability  and BCS will  refund  all  amounts  paid to BCS for the
returned Product plus transportation  charges from BCS' plant and return; or (c)
have the Product  replaced  by BCS as  promptly  as possible by giving  Ordering
Company  priority  over other  customers at no  additional  charge.  If Ordering
Company  elects to reject the  Product,  it must do so in  writing  and within a
reasonable time frame.

                  (b)  BCS  will  make  reasonable  accommodations  if  Ordering
Company requests a delay in the originally scheduled In-Service Date if Ordering
Company  gives BCS written  notice prior to the CCD. If Ordering  Company  gives
notice of a request for delay in the originally  scheduled In-Service Date after
the CCD,  requests more than one delay in the In-Service  Date prior to the CCD,
or  causes a delay in the  In-Service  Date as a result  of  Ordering  Company's
failure to meet its obligations (e.g., its obligations under Section 13.6) under
this  Agreement,  Ordering  Company and BCS will mutually  agree to either:  (i)
deliver the Products and commence billing as of the originally scheduled
In-Service  Date, in which case  installation  will be rescheduled at a mutually
agreeable time and additional installation charges may apply; or (ii) cancel the
Order and bill Ordering Company for cancellation  charges as set forth in Part 1
of this GPA.  Notwithstanding the foregoing  provisions of this Section 14.4(b),
Ordering  Company  may  delay  delivery  one time for up to  thirty  (30)  days,
provided Ordering Company has given BCS seven (7) business days' notice prior to
the scheduled ship date.

                  (c) For BCS-installed Products, BCS will perform a site survey
to identify Ordering Company's specific installation  requirements.  If the site
survey  cannot be  performed  prior to the  execution  of an  Order,  it will be
scheduled and conducted as soon as Ordering




<PAGE>




Company's facilities are available. Upon completion of the site survey, BCS will
identify and  communicate to Ordering  Company any  additional  charges that may
apply.  If there were  additional  charges  identified  during the site  survey,
Ordering Company may cancel the Order without incurring  cancellation charges if
Ordering  Company  notifies  BCS in  writing  within  ten (10) days of  Ordering
Company's receipt of the notice from BCS of the additional charges.

                  (d) Installation and shipping charges may be
adjusted if
Ordering Company changes the installation location.

                  14.5 PRODUCT WARRANTY.

                  (a) BCS warrants  that as of the date title  passes,  BCS will
have the right to sell,  transfer  and assign  Products  and the title  conveyed
shall be good and Products shall be delivered  free from any security  interests
or any other liens or encumbrances.

                  (b) For purposes of Sections 14.5(b) through 14.5(g) only, the
term  "Product"  also includes the  Product's  associated  Software.  During the
warranty period,  BCS warrants to Ordering  Company that the Products  furnished
shall conform to and perform in accordance with BCS's standard specifications or
documentation  and any other mutually agreed  specifications.  In addition,  BCS
warrants to Ordering  Company that the Products shall be  merchantable  and free
from defects in design (except to the extent (i) designed by Ordering Company or
(ii) design  defects are caused by the presence in BCS's  Product of  substitute
components of Ordering Company's selection not recommended by BCS), material and
workmanship. BCS also warrants that the Products will be new, remanufactured, or
refurbished,  and that  installation  and other  services will be performed in a
first-class workmanlike manner.

confirmation  of the Order and shall  begin on the  Delivery  Date for  Ordering
Company-installed Products or on the In-Service Date for
BCS-installed Products.

significant  problems  occur such that  acceptance  is delayed for more than ten
(10) days  following  Ordering  Company's  notice  concerning  such  significant
problems,  the warranty  period shall  commence  upon  acceptance.  The warranty
period shall be one year if none is specified  on the Order or  confirmation  of

                   (e)  If a  Product  (including  any  associated  Installation
Services)  does  not meet the  above  warranties  during  the  warranty  period,
Ordering  Company shall promptly notify BCS. BCS shall take the following action
promptly:

         (i)  Within  the first  sixty  (60)  days of the
warranty  period,  if
         Ordering Company notifies BCS of a defect or
non-conformity  that does
         not  appear  to be  curable  through  repair  or
replacement  within a
         reasonable  time period,  Ordering  Company  will be
entitled,  at its
         option,  to a refund of the Product's  purchase price
and  installation
         charges upon return of the Product. Should Ordering
Company seek such a
         refund, it will provide BCS such cooperation as necessary
to enable BCS
         to remove the Product from Ordering Company's  premises,
if necessary.
         Transportation  costs and risk of loss or damage  in
transit  shall be
         borne by BCS. In the event of such a refund,  Ordering
Company may also
         return  for  credit any other BCS  Products  intended
for use with the
         defective  Product  that  cannot be applied to another
use by Ordering
         Company and may cancel, without liability for
cancellation charges, any
         pending Orders for such Products.

         (ii) After sixty (60) days, BCS, at its option,  shall
attempt first to
         repair or replace  such  Product  without  charge or, if
not  feasible,
         refund the original  purchase price and  installation
charges.  In the
         event  of  such  refund,   Ordering  Company  shall
provide  BCS  such
         cooperation  as  necessary  to enable  BCS to remove the
Product  from
         Ordering Company's  premises,  if necessary.
Transportation  costs and
         risk of loss or damage in transit  shall be borne by BCS.
In  addition,
         in the event of such  refund,  Ordering  Company  may
also  return  for
         credit  any  other BCS  Products  intended  for use with
the  defective
         Product  that cannot be applied to another use by
Ordering  Company and
         may cancel,  without  liability for cancellation
charges,  any pending
         Orders for such Product.

                  (f) All  warranties  shall  continue  in full force and effect
notwithstanding  transfer  of  title  (except  for  title  to  their  associated
Software) to the Products by Ordering  Company,  so long as Ordering  Company or
its Affiliates  shall remain the user of the Product.  All warranties shall also
survive inspection, acceptance and payment.

                  (g) THE FOREGOING PRODUCT  WARRANTIES ARE
EXCLUSIVE AND ARE IN
LIEU OF ALL OTHER EXPRESS AND IMPLIED  WARRANTIES,  INCLUDING BUT
NOT LIMITED TO
WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE. EXCEPT FOR (1)
TANGIBLE PROPERTY
DAMAGE  AND  PERSONAL  INJURY  FOR WHICH BCS IS HELD  LIABLE  AND
(2) THE REMEDY
PROVIDED IN SECTION 5.1(E),  ORDERING  COMPANY'S SOLE AND
EXCLUSIVE REMEDY SHALL
BE BCS'S OBLIGATION TO REPAIR, REPLACE,  CREDIT, OR REFUND AS SET
FORTH ABOVE IN
THIS WARRANTY.

                  (b) The warranty  provided in Section  14.5 and  post-warranty
service do not cover repair for damages or  malfunctions  caused by: (1) actions
of non-BCS  personnel or the  attachment  to the  Products of non-BCS  furnished
equipment  or  Software;   (2)  Ordering   Company's  failure  to  follow  BCS's

Company's  failure to permit  BCS timely  remote  access to  Ordering  Company's
Products;  (3) failure of products  not  serviced by BCS;  (4) abuse,  misuse or
negligent acts of non-BCS personnel;  or (5) Force Majeure conditions  following

service if Ordering Company modifies the Software. If Ordering Company requests,
BCS will  perform  repair or other  services  not covered by this  Agreement  to
Ordering  Company's  BCS  Products  at the  mutually  agreed  to rates  for such
service.

                  (c)  Additional  charges  may apply if BCS  incurs  additional
costs  in  providing  warranty  or  post-warranty  services  as  a  result  of a
modification of Products.  Unless otherwise agreed, BCS shall not be responsible
to provide warranty or post-warranty  Maintenance  Services, if Ordering Company
has moved a Product without notifying BCS.

                  (d) BCS DOES NOT WARRANT UNINTERRUPTED OR
ERROR-FREE OPERATION
OF THE PRODUCTS AND BCS DOES NOT WARRANT THAT THE PRODUCTS WILL
PREVENT, AND BCS
WILL NOT BE  RESPONSIBLE  FOR,  UNAUTHORIZED  USE (OR  CHARGES
FOR SUCH USE) OF
COMMON  CARRIER  TELECOMMUNICATION  SERVICES OR FACILITIES
ACCESSED  THROUGH OR
CONNECTED TO PRODUCTS. ORDERING COMPANY MAY PURCHASE BCS'S TOLL
FRAUD PROTECTION
PRODUCTS OR OFFERINGS (E.G.,  DEFINITY TOLL FRAUD INDEMNITY OFFER) IF IT CHOOSES
TO DO SO, PROVIDED BCS CONTINUES SUCH OFFERING.

                  14.7  DOCUMENTATION.  BCS shall furnish to Ordering Company at
no additional charge and grant Ordering Company the right to use one copy of the
documentation   for  each  unit  of  the  Products  provided   hereunder.   Such
documentation  will be that  customarily  provided by BCS to its customers,  for
that  Product,  at no  additional  charge.  BCS shall also  furnish to  Ordering

BCS to Ordering
Company.  Additional  copies of the  documentation  are
available  at  mutually
agreeable prices.

                  14.8  SPECIFICATIONS.  Upon  request,  BCS  shall  provide  to
Ordering Company,  at no charge, and grant Ordering Company the right to use and
reproduce a copy of BCS's  available  commercial  Specifications  applicable  to
Products ordered hereunder. In addition, a copy of BCS's Specifications shall be
provided with each unit.  Additional copies are available at mutually  agreeable

                  14.9  REGISTRATION  AND  RADIATION  STANDARDS.  When a Product
furnished  under this Part III is subject to Part 68,  Part 15 or any other part
of the Federal Communications Commission's Rules and Regulations, as they may be
amended from time to time,  (hereinafter  "FCC  Rules"),  BCS warrants that such
Product complies with the registration,  certification,  type-acceptance  and/or
verification standards of FCC Rules including, but not limited to, all labeling,
customer instruction requirements, and the suppression of radiation to specified
levels.  BCS shall also establish  periodic  ongoing  compliance  re-testing and
follow a Quality Control  program,  to assure that Product shipped complies with
the  applicable  FCC Rules.  BCS agrees to indemnify and save  Ordering  Company
harmless from any liability,  claims, or demands (including costs,  expenses and
reasonable attorney's fees on account thereof) that may be made because of BCS's
noncompliance  with the  applicable  FCC Rules.  BCS  agrees to defend  Ordering
Company, at Ordering Company's request, against such liability, claim or demand.
In addition, should Product which is subject to Part 15 of the FCC Rules, during
use generate harmful interference to radio communications,  BCS shall provide to
Ordering   Company   information   relating  to  methods  of  suppressing   such
interference and pay the cost of suppressing such interference or, at the option
of Ordering Company, accept return of the Product and refund to Ordering Company
the price paid for the Product less a  reasonable  amount for  depreciation,  if
applicable.  Nothing  in this  Section  14.9  shall be  deemed  to  diminish  or

shall be marked for  identification  purposes in accordance with mutually agreed
upon  marking  specifications.  Such  specifications  shall  be set  forth  in a
Supplemental  Agreement  or Order.  All such  Product  shall also be marked with

                                   ARTICLE XV
                                    SOFTWARE

                  15.1 GENERAL.

                  (a) The  provisions of this Article 15 apply to the furnishing
of Software by BCS to Ordering Company pursuant to this Agreement. The ownership
interests  and rights of the  parties in Custom  Software,  in  addition  to the
applicable  rights  set  forth  in  this  Article,  shall  be  established  on a
case-by-case basis in subsequent Supplemental Agreements.

                  (b) To the extent that any provision set forth in this Article
conflicts with any provision set forth elsewhere in this Agreement, this Article
shall control.

                  (c) Software in this Article means both Custom
Software and
Licensed Materials.

                  15.2 SOFTWARE LICENSE.

                  (a) BCS grants Ordering  Company a personal,  non-transferable
(except to the extent allowed in Section 15.2(d) below) and non-exclusive  right
to use, in object code form,  all Licensed  Materials and related  documentation
furnished under this Agreement. Title to and ownership of all Licensed Materials
shall remain with BCS or its suppliers.  This grant shall be limited to use with
the equipment  for which the Licensed  Materials was obtained or, on a temporary
basis, on back-up  equipment when the original  equipment is inoperable.  Use of
Licensed Materials on multiple  processors is prohibited unless otherwise agreed
to in  writing by BCS.  Ordering  Company  will not  reverse  assemble,  reverse
compile, disassemble or decompile the Licensed Materials to derive a source code
equivalent of the Licensed  Materials.  Ordering  Company will take  appropriate
action to  instruct  Ordering  Company's  employees  and  users of all  Licensed
Materials of Ordering Company's obligations under this Section.

                  (b) Ordering Company may make a reasonable number of copies of
Licensed Materials,  solely for the purpose of back-up or archival use. Any such
copy must contain the same  copyright  and other  notices and markings  that the
original Licensed Materials contains. Use of Licensed Materials on any equipment
other than that for which it was obtained or removal of Licensed  Materials from
the  United  States  or  other  country  in which  the  Licensed  Materials  was
originally  deployed  (without  written  consent  of  BCS,  which  will  not  be
unreasonably withheld), or reverse assembly, reverse compilation, disassembly or
decompilation of the Licensed Materials to derive a source code equivalent shall
immediately  and  automatically  terminate  the  license  with  respect  to  the
particular unit of the Licensed Materials. If Ordering Company commits any other
material breach of the Licensed Materials license, the conditions of Article 5A,
ARBITRATION;  DISPUTE  RESOLUTION shall apply. BCS's cancellation of the license
at issue shall be tolled pending the outcome of the Dispute Resolution  process.
Simultaneous with initial invocation of


<PAGE>





such process, Ordering Company shall deposit and have held in escrow, until such
dispute is resolved,  an amount equal to the current market price of the license
in question.

                  (c) BCS may provide  Ordering Company with Software that bears
the logo or copyright of another  company.  If BCS provides such Software with a
"shrinkwrap"  or other license from the other company,  those terms apply rather
than the license terms in this Agreement. If Ordering Company requests, BCS will
give Ordering Company a copy of such other license terms before Ordering Company
orders the Software.

                  (d) If the equipment  purchased  hereunder is sold or assigned
to another  party,  BCS  requires  that the new owner or assignee  execute a new
Licensed  Materials license and pay the then current Licensed  Materials license
fee, if any. Upon written  request,  BCS will grant the new owner or assignee of
the equipment the right to use any related Licensed Materials,  provided the new
owner or assignee  agrees,  in writing,  to BCS's terms and  conditions and pays
BCS's then current Licensed Materials license fee. BCS shall seek to enforce its
rights in the first instance against the new owner or assignee. If the new owner
or assignee of the equipment refuses to execute a new Licensed Materials license
agreement  or pay the  applicable  Licensed  Materials  license  fee,  or if the
equipment is no longer to be used by Ordering  Company,  Ordering  Company shall
either return the Licensed  Materials,  together with any copies, or destroy the
Licensed Materials and all copies, and provide BCS with prompt written notice of
such  destruction.  Notwithstanding  the  preceding  provisions  of this Section
15.2(d),  Ordering  Company  may  transfer  the  Licensed  Materials  to another
Ordering Company in connection with a transfer of the associated equipment,  and
BCS will not charge the new Ordering  Company a Licensed  Materials  license fee
therefor.

                  15.3  SOFTWARE.  On the delivery  date,  BCS shall  furnish to
Ordering Company,  at the fee specified in the Order or Supplemental  Agreement,
at least the following basic items:

                  (a)  Object  Code  stored  in a  medium
compatible  with  the
equipment,  as described in BCS's  Specifications,  the
applicable  Supplemental
Agreement or the Order;

                  (b)  User  documentation   which  BCS  normally  furnishes  to
customers  with the Licensed  Materials at no  additional  charge,  and any user
documentation specified in the applicable Supplemental Agreement; and

                  (c) If appropriate and if not previously
provided, the
required machine configuration.

                  15.4  INSTALLATION  OF  SOFTWARE.  Where  Ordering  Company is
responsible  for  installation  of  Software,  BCS's sole  responsibility  is to
deliver the  Software to Ordering  Company on or before the  scheduled  Delivery
Date  specified  in the  Order or  Supplemental  Agreement.  However,  if BCS is
responsible  for such  installation,  BCS shall deliver the Software to Ordering
Company in sufficient time for it to be installed on or before the scheduled In-



<PAGE>





Service Date  specified in the Order or  Supplemental  Agreement,  and BCS shall
complete its installation and associated testing on or before such date.

                  15.5 CENTRALIZED MAINTENANCE.  Ordering Company
may specify in
an Order that,  for  centralized  maintenance  purposes,  all
Software  changes,
including  Enhancements,  provided by BCS shall be provided only to the Ordering
Company's  Centralized  Support  Organization.  BCS  will,  in  that  event,  be
responsive to  maintenance  requests  which the Ordering  Company's  Centralized
Support  Organization issues. This Organization will be responsible for Software
application,  initial acceptance testing and distribution of the Software to all
licensed  installations.  BCS grants Ordering  Company the right to transmit the
Software  by means of data links from  Ordering  Company's  Centralized  Support
Organization to each licensed  installation.  BCS grants to Ordering Company, at
no  additional  fee, a license  to use a copy of the  Software  for  centralized
maintenance  purposes  only.  BCS shall  provide  this  maintenance  copy of the
Software in response to an Order  requesting same. The maintenance copy provided
to the Ordering Company's  Centralized Support Organization will be used only to
perform  systems or  application  support  functions for the Ordering  Company's
application programmers, except as provided hereinafter. If the maintenance copy
of the  Software  provided  pursuant to this  Section  15.5 or a copy thereof is
later incorporated by the Ordering Company's  Centralized  Support  Organization
into a Ordering Company system or application support Software, Ordering Company
shall notify BCS and shall pay BCS the current  applicable rate paid by Ordering
Company for use of the Software.

                  15.6  ENHANCEMENTS.  BCS shall  promptly  furnish to  Ordering
Company during the duration of the Order, at an agreed upon charge,  if any, all
Software  Enhancements and telephone technical  assistance made available by BCS
to  commercial  customers  and shall  promptly  provide to Ordering  Company any
revisions  to the basic  Software  items  defined in Section 15.3 to reflect the
Enhancements.  All  Enhancements  shall be  considered  Software  subject to the
provisions of the Order.  Ordering Company may incorporate the Enhancements into
the Software or continue  using previous  versions of the Software,  at Ordering
Company's  option.  Ordering  Company  may,  at any time and at its  discretion,
discontinue  maintenance of the Software.  BCS shall not charge Ordering Company
for Quality  Protection Plan Change Notices  (QPPCNs) during the warranty period
or during any contracted-for  post-warranty  maintenance period. If the QPPCN is
required for warranty or post-warranty  service, and Ordering Company elects not
to obtain the QPPCN,  continuation of warranty or  post-warranty  service may be
subject to additional charges.

                  15.7 TRAINING AND TECHNICAL SERVICE. BCS shall
provide such
assistance, advice and training at no additional charge, as it
normally provides
without charge to other customers.

                  15.8 SOFTWARE WARRANTY. BCS warrants to Ordering
Company all
of the following:




<PAGE>




                  (a) The Software will be free from  significant  errors,  will
conform to and perform in accordance with the  Specifications  and will function
properly. The Media conveying the Software will be free from defects in material
and  workmanship.  The  Software  will  be  compatible  with  and may be used in
conjunction with other Software as described in the Specifications.  If an Order
states  that  the  Software  is to be  used  in  conjunction  with  certain  BCS
equipment,  the Software shall be compatible with that equipment.  The foregoing
warranties  extend to the future  performance of the Software and shall continue
for one year except as otherwise specified in a Supplemental Agreement or Order.

                  (b) Software-related Work will be performed in a
first-class,
workmanlike manner.

                  (c) With respect to BCS-developed Software,  there are no copy
protection or similar  mechanisms  within the Software which will, either now or
in the future,  interfere  with the grants made in this  Agreement or an Order .
With respect to non-BCS developed  Software,  BCS will use reasonable efforts to
insure  that  there are no copy  protection  or  similar  mechanisms  within the
Software which will, either now or in the future, interfere with the grants made
in this Agreement or an Order.

                  (d) Ordering Company shall have quiet enjoyment
of the
Software.

                  (e) As to  Software  for  which  BCS does not  solely  own all
intellectual property rights, BCS has full right, power and authority to license
the Software to Ordering Company as provided in this Agreement or an Order.

                  (f) If the  Software,  or any portion  thereof,  is or becomes
unusable,  totally,  or in any respect during the applicable warranty period, or
if the work  fails to meet the  warranties,  BCS will  reperform  work,  correct
errors,  defects and  nonconformities  and restore  the  Software to  conforming
condition free of significant  errors at no cost to Ordering Company.  Corrected
Software shall be warranted as set forth in this clause.

                  (g) The Software does not contain any malicious code, program,
or other internal component (e.g.  computer virus,  computer worm, computer time
bomb, or similar  component),  which could damage,  destroy,  or alter Software,
firmware, or hardware or which could, in any manner, reveal, damage, destroy, or
alter  any  data or other  information  accessed  through  or  processed  by the
Software  in any manner.  BCS shall  immediately  advise  Ordering  Company,  in
writing,  upon  reasonable  suspicion  or  actual  knowledge  that the  Software
provided  under  this  Agreement  or an Order may  result in the harm  described
above.

                  (h) All warranties shall survive inspection,
acceptance and
payment.

                  15.9 RELATED DOCUMENTATION. BCS shall furnish to
Ordering
Company, at no additional charge, and grant Ordering Company the
right to use
one copy of the related




<PAGE>




documentation  for each unit of the  Software  furnished by BCS pursuant to this
Agreement for the sole purpose of operating and maintaining such Software.  Such
related  documentation will be that customarily provided by BCS to its customers
for such  Software,  consistent  with the  vintage,  options  and feature of the
system on which it operates.  Such related documentation shall be provided prior
to or included with provision of Software by BCS to Ordering Company. Additional
copies of the related  documentation  are available at prices set forth in BCS's
Price List.

                  15.10  NOTIFICATION OF DISCONTINUED  AVAILABILITY OF SOFTWARE.
BCS  shall  notify  Ordering  Company  at  least  one  (1)  year in  advance  of
discontinued  availability of the last standard Software generic.  For a minimum
of two (2) years after  discontinued  availability,  BCS will make  available to
Ordering  Company,  Software  support  service  which affords  Ordering  Company
reasonable continued use of the Software.

                  15.11 RISK OF LOSS.  If any  Software  fixed in Media is lost,
damaged or made invalid during shipment,  BCS will promptly replace the Software
and Media therefor at no additional charge to Ordering Company.  If any Software
is lost or  damaged  while  in the  possession  of  Ordering  Company,  BCS will
promptly replace the Software at mutually agreed charges.

                           15.12 ACCESS TO SOURCE CODE

                  (a) If Supplier is declared bankrupt,  and as a result of such
bankruptcy,  BCS is unable to  maintain  Software  so that  Ordering  Company is
unable to use the Software,  then BCS shall furnish to Ordering Company (under a
suitable license  agreement,  if applicable) BCS's then existing Software Source
Code and associated  documentation for the affected Product(s) for such standard
version  only to the  extent to allow  Ordering  Company  to use  solely for its
internal  purposes  such  Software for which  Ordering  Company has a perpetual,
non-exclusive right to use.

                  (b) If  Ordering  Company's  use of the  Software  Source Code
provided  pursuant to Section  15.12(a)  involves use or copying of  copyrighted
material or the practice of any invention  covered by a patent,  Supplier  shall
not assert the  copyright  or patent  against  Ordering  Company  for use of the
Software Source Code as originally  provided by Supplier within the scope of the
rights granted in Section 15.12(a).

                  (c) The parties may negotiate  additional  rights for Ordering
Company to access  particular  Software Source Code on a case-by-case  basis, as

                                    Form of
                           VOLUME PURCHASE AGREEMENT

        THIS Volume Purchase  Agreement  ("Agreement")  dated as of November 20,
1996  is  between  AT&T  Corp.,  a  New  York  corporation  ("AT&T"),   and  NCR
Corporation, a Maryland corporation ("NCR").

        WHEREAS, the Board of Directors of AT&T has determined that it is in the
best  interests  of AT&T  and  its  shareholders  to  separate  AT&T's  existing
businesses into three independent businesses;

        WHEREAS,  in  furtherance  of the  foregoing,  AT&T and NCR will,  on or
before  January 1, 1997,  execute and deliver a Distribution  Agreement,  by and
between AT&T and NCR (the "Distribution Agreement").

        WHEREAS,  this Agreement is one of the NCE Ancillary Agreements (as such
term is defined in the Distribution  Agreement) contemplated by the Distribution
Agreement; and

        WHEREAS,  in  anticipation  of NCR's  spin-off,  AT&T and NCR  desire to
memorialize  and formalize the volume,  prices,  and other terms and  conditions
under which AT&T will buy products and services from NCR in 1997 and thereafter.

        NOW THEREFORE, AT&T and NCR agree as follows:

1. TERM OF AGREEMENT.  (a) Except as otherwise expressly provided herein or in a
subsequent  agreement  between the  parties,  the terms and  conditions  of this
Agreement  and the General  Agreement  between the parties of even date herewith
shall govern all of AT&T's  purchases of products and services  from NCR fro the
five-year  period  beginning as of January 1, 1997 and ending December 31, 2001,
unless this Agreement is terminated sooner as permitted by Section 1(b).

        (b) Upon at least  90 days'  prior  written  notice,  either  party  may
terminate  this  Agreement for its  convenience,  without  requirement of cause,
provided that the effective date of such  termination is after expiration of the
Purchasing Period described in Section 2.

2.      COMMITMENT

        (a) Under the terms and conditions of this Agreement,  during the period
beginning  January 1, 1997 and ending  December 31, 1999  ("Purchasing  Period")
AT&T  contractually  commits to purchase  not less than $350 million of products
and services from NCR or any present or future subsidiaries or affiliates of NCR
(collectively "NCR Entities")  ("Commitment"),  unless the Commitment is reduced
or  terminated  as provided in Section 7. AT&T may satisfy  this  Commitment  by
purchasing  the entire  Commitment  amount of products or services in any of the
three years or  cumulatively  over the three years. If AT&T fails to satisfy the
Commitment,  the adjustment  described in Section 9 shall apply.  Subject to the
clause in Article VI of the General Agreement  entitled SCOPE OF AGREEMENT,  any
purchases of Eligible Products, as hereinafter defined, by any present or future
subsidiary or other affiliate of AT&T (collectively, the "AT&T Entities") during
the  Purchasing  Period  shall be  included  in the  calculation  of whether the
Commitment has been satisfied.

        (b) Upon  written  notice to NCR,  AT&T may, at its  option,  extend the
Purchasing  Period until December 31, 2000 and/or December 31, 2001,  subject to
Sections 9(a) and 9(b).

3. PRODUCTS AND SERVICES.  The NCR products and services which the AT&T Entities
may purchase in satisfaction of the Commitment ("Eligible Products") include all
present and future  products and services of any NCR Entity except products that
are exclusive to the Personal Computer,  Retail, and/or Financial product lines.
Eligible Products include,  but are not limited to, the following:  Professional
Services;  Customer Support Services (including without limitation Large Systems
Support  and  Software  Support;  repair  and  replacement  parts and  technical
support;   and  all  products  and  services  purchased  in  support  of  AT&T's
self-maintenance activities, including any parts purchased in the fourth quarter
of 1996 in contemplation of NCR's spin-off,  systems infrastructure and customer
engineer  education);  Servers;  Massively Parallel  Processors;  Software;  and
Networking Products.  The AT&T Entities may purchase Eligible Products for their
own internal use or (pursuant to the terms of a separate written  agreement) for
resale worldwide (but with the applicable AT&T Entity  additionally  responsible
for any customs,  duties,  or local country  taxes  incurred by NCR by providing
products and services  outside the United States),  provided that the applicable
AT&T products or services to a customer ("Solutions Sale"), and provided further
that if the AT&T Entity receives written notice that NCR has






<PAGE>

entered into an exclusive  distribution  agreement with a third party in a given
foreign country, that AT&T Entity will not be authorized hereunder to resell NCR
products and  services in that foreign  country  without  obtaining  NCR's prior
written consent,  which consent will not be unreasonably  withheld or delayed if
the resale can be accomplished without violation of such exclusive  distribution
agreement.  Subsidiaries  acquired by Supplier  after the effective date of this
Agreement  shall have their  products  and services  added to this  Agreement at
mutually agreeable discount rates.

4.  INDIRECT  PURCHASES.  Subject to the  clause in  Article  VI of the  General
Agreement  entitled SCOPE OF AGREEMENT,  if the AT&T Entities  purchase Eligible
Products  from  any of  NCR's  authorized  Value  Added  Resellers  ("VARs")  or
Independent  Software  Vendors  ("ISVs")  or from a third  party  NCR  exclusive
distributor  in  a  given  foreign  country,  NCR  will  credit  towards  AT&T's
Commitment  hereunder,  the price paid by the AT&T  Entities to the VAR,  ISV or
third party foreign distributor for components produced by NCR.

5.      PRICES. Unless the parties otherwise mutually agree, and
except as
required by Section 6, NCR prices to the AT&T Entities for the
Purchasing
Period shall be determined as follows:

        (a) For all NCR  products  and  services  for which NCR has  published a
Manufacturer's  Suggested  References  Price  ("MSRP"),  the  price  to the AT&T
Entities shall be the MSRP reduced by a Discount  calculated in accordance  with
Section 5(b).  NCR has furnished AT&T with a list of MSRPs for all such products
and  services  and  thereafter  shall  provide AT&T not less than 30 days' prior
written  notice of any  changes to the MSRP list.  For  United  States  Customer
Support Services, any increase in the MSRP for Customer Support Services (or any
component  thereof)  shall not exceed the  percentage  increase in the  Consumer
Price Index - All Urban Wage  Earners  and  Clerical  Workers,  as issued by the
Bureau of Labor  Statistics  of the United  States  Department  of Labor ("CPI")
relative  to the CPI that was in effect on the later of  January  1, 1996 or the
date the previous list price became effective.

        (b) For each category of NCR product or service, the Discount shall be a
percentage  equal to the  effective  discount off MSRP that was  available as of
January  1, 1996  under the  lowest  NCR  prices  regularly  offered to any AT&T
business  unit.  The  formula  for  calculating  the  Discount,  using  MSRP and
discounted price in effect as of January 1, 1996 is as follows:




<PAGE>

     (1/1/96 MSRP - 1/1/96 discounted price)         x 100 =
Discount (%)
     ---------------------------------------
                   1/1/96 MSRP

Based on this formula,  NCR and AT&T will establish the percentage amount of the
Discount for each product or service category by mutual written agreement.

        (c) For all NCR products and services for which NCR has not published an
MSRP, NCR and AT&T shall negotiate prices in good faith. Such prices shall yield
margins to NCR not greater than the margins realized on comparable  products and
services priced in accordance with Section 5(a).

        (d) In order for NCR to comply with all applicable laws and regulations,
NCR's  prices  for  products  and  services  which  the AT&T  Entities  purchase
indirectly  through VARs and ISVs will be NCR's  standard  prices in effect with
such VARs and ISVs,  and  NCR's  prices  for  products  which the AT&T  Entities
purchase for Solution  Sales in which title to the NCR product passes to an AT&T
customer will be NCR's standard  resale prices or such prices as the parties may
separately negotiate ("Indirect and Resale Prices").

        (e) In the event that NCR  redefines  its  pricing  strategy in a manner
that would make the current model pricing obsolete, the AT&T Entities shall have
the option to move to this new  pricing  paradigm  in its  entirety  through the
remaining term of this Agreement.  Should a new pricing paradigm occur, only new
products/service transactions would be impacted through this change.

        (f) NCR may,  from time to time,  offer AT&T to  substitute  upgraded or
later-developed  items  of  equipment,  components  or  parts  for the  products
purchased  herein.  In such  event,  NCR will  allow a  trade-in  credit for the
equipment being traded-in toward the purchase of the upgraded or later-developed
equipment.  the trade-in credit shall be in accordance with mutually agreed upon
allowances in effect at the time of such trade-in.

6.      MOST FAVORED CUSTOMER STATUS.

        (a) For the Purchasing  Period,  NCR agrees that all prices,  except for
Indirect and Resale Prices and non-United States services prices, charged to the
AT&T Entities under this  Agreement  shall be as favorable as any prices offered
or charged by NCR during the preceding 12-month period to any other NCR customer
making a comparable purchasing commitment,  in each case taking into account the
value of terms  and  conditions  of sale.  With  respect  to  non-United  States
services pricing, prices charged to the AT&T Entities in any given country




<PAGE>

shall be as  favorable  as any  prices  offered  or  charged  by NCR  during the
preceding  12-month  period  to any  other  NCR  customer  making  a  comparable
purchasing  commitment  for  comparable  services in that country,  in each case
taking into account the value of terms and  conditions of sale.  For purposes of
this Section 6, the  purchasing  commitment  made to NCR by Lucent  Technologies
Inc., and the terms and conditions of sale applicable  thereto,  shall be deemed
comparable  to those of the AT&T Entities  under this  Agreement and the General
Agreement.  If NCR  charges a more  favorable  price  (other than an Indirect or
Resale Price) to any such NCR customer,  NCR shall  immediately  reduce the AT&T
Entities  price as necessary to comply with this Section 6;  provided,  however,
that AT&T's and the AT&T's Entities' sole remedy for NCR's unintentional  breach
of this requirement shall be to recover from NCR the difference between what the
applicable  AT&T Entity was  actually  charged and what should have been charged
had NCR complied with its obligations hereunder.  Notwithstanding the foregoing,
NCR may offer or charge more  favorable  prices to other NCR  customers  without
lowering the prices to the AT&T Entities under this Agreement, provided any such
more  favorable  prices  are  offered  or  charged  for the  limited  purpose of
initiating a new customer  relationship,  reestablishing a customer relationship
that has been  discontinued  for no less  than six (6)  months or  expanding  an
existing  customer  relationship  by selling  products or services of a type not
previously  sold to that  customer  during the  previous 12 months and  provided
further that such more favorable prices are not offered or charged for more than
6 months.

        (b) At AT&T's  request,  but not more frequently than once each calendar
year,  NCR's  compliance  with its  obligations  under  this  Section 6 shall be
subject to an audit of reasonable scope by an independent auditing firm selected
by AT&T and reasonably  satisfactory to NCR. AT&T will bear the auditing firms's
charges.  The audit  will be  conducted  in a manner  that will  minimize  NCR's
inconvenience  and expense in  providing  information  necessary  to perform the
audit. Prior to the auditor submitting  findings to AT&T, NCR will be afforded a
reasonable  opportunity to review and comment on any preliminary  finding by the
auditor  that NCR has failed to fulfill  its  obligation  under this  Section 6.
Prior  to  the   commencement  of  each  audit,   the  auditor  will  execute  a
non-disclosure  agreement  reasonably  acceptable  to NCR which will require the
auditor to hold all  information  received from NCR in  confidence,  except such
information contained in the auditor's final report (which shall be disclosed to
AT&T only upon AT&T's entry into a non-disclosure  agreement acceptable to NCR.)
Should the auditor  determine that NCR has not fulfilled its  obligations  under
this Section 6, NCR will issue AT&T a credit (without interest) in the









<PAGE>



amount determined to be the difference between what AT&T paid and the price that
AT&T would  have paid had NCR  complied  with its  obligations  hereunder.  Such
credit may be reduced by the amount of any underbillings  which may be disclosed
by the audit and substantiated with evidence reasonably satisfactory to AT&T.

7. ADJUSTMENTS TO COMMITMENT.  The parties recognize that future events may make
it impractical or inequitable for the AT&T Entities to purchase NCR products and
services  in the  amounts  contemplated  by  the  Commitment.  Accordingly,  the
Commitment  shall be reduced in amount,  or terminated and  extinguished  in its
entirety, under the circumstances described in this Section 7.

        (a)  If an  AT&T  Competitor  (as  hereinafter  defined)  enters  into a
relationship  with NCR that  would  potentially  enable the AT&T  Competitor  to
obtain  AT&T   (including  its   subsidiaries)   proprietary   or   confidential
information,  NCR  will  take  all  necessary  steps  to  assure  that  the AT&T
Competitor does not have access to such  information  through NCR without AT&T's
express prior written  consent.  In addition,  if at any time an AT&T Competitor
owns or controls shares representing a controlling interest in NCR, AT&T may, at
its option,  terminate the  Commitment at any time by giving  written  notice to
NCR. Upon any such  termination,  the Commitment shall be  extinguished,  AT&T's
obligation  thereunder  shall be deemed entirely  fulfilled,  and the Purchasing
Period shall  terminate.  For purposes of this Agreement,  an AT&T Competitor is
any  company,  person,  or other  entity  which,  either  directly or through an
affiliate,  offers (or has  announced  future  availability  of) any  product or
service that AT&T reasonably  determines to be substantially  competitive with a
product or service  offered or announced by AT&T  (including its  subsidiaries);
provided,  that a third party will not be deemed an AT&T Competitor  unless AT&T
(including its  subsidiaries) and such third party each have aggregate actual or
forecasted annual revenues from substantially  competitive products and services
exceeding $250 MILLION for at least one year of the Purchasing Period.

        (b) If AT&T or a  controlled  United  States  subsidiary  purchases  any
information  technology  product or service from a third party  ("Alternative IT
Supplier")  because the  available  Eligible  Products do not meet its needs (as
defined in this Section 7(b)),  the amount of the Commitment shall be reduced by
the amount of each such purchase from the Alternative IT Supplier.  For purposes
of this  Section  7(b),  failure  to meet the  needs of AT&T or such  controlled
United  States  subsidiary  means  circumstances  substantially  similar  to the
following:




<PAGE>

        (i) NCR has  discontinued  an Eligible  Product and has
not  replaced it
        with a  comparable,  technologically  compatible
Eligible  Product that
        delivers equal or better performance, features, and value.

        (ii) NCR is unable or  unwilling  to provide  the
delivery  interval or
        response time  reasonably  required by AT&T or such
affected  subsidiary
        for an Eligible Product, or imposes unreasonable charges
to do so.

        (iii)  Multiple  units  of an  Eligible  Product  do not
meet  industry
        standards  or the  reasonable  requirements  of AT&T  or
such  affected
        subsidiary for quality, performance, or reliability.

        (iv) A  substantial  number of units of an Eligible
Product have had an
        excessive failure rate, or have performed below NCR's
specifications.

        (c) If AT&T or a  controlled  United  States  subsidiary  purchases  any
Information  Technology  product  or service  from an  Alternative  IT  Supplier
because NCR has  unreasonably  refused to modify,  extend,  or adapt an Eligible
Product  to offer  functionality,  features,  performance,  or  interoperability
required by AT&T or such affected subsidiary, the Commitment may be reduced by a
mutually  agreed  amount  (or absent  such  agreement,  by an amount  determined
pursuant to Article V DISPUTE RESOLUTION of the General Agreement, not to exceed
the amount of each such purchase from the Alternative IT Supplier). For purposes
of this Section 7(c), the extent to which NCR's refusal was  reasonable  will be
evaluated by considering such factors as (i) whether NCR possessed the requisite
know-how (and, if applicable,  the production  capability) to accommodate AT&T's
or such affected  subsidiary's  request,  (ii) whether the new Eligible  Product
could have been  marketed to other  customers in markets that NCR is  addressing
now and new  markets it may address in the future,  (iii)  whether  AT&T or such
affected  subsidiary has offered to pay a reasonable  price for the new Eligible
Product, taking into account NCR's anticipated costs and the potential for sales
to other customers,  and (iv) whether the development  requested by AT&T or such
affected  subsidiary  is necessary to sustain the  utility,  functionality,  and
value of other Eligible Products purchased by AT&T or such affected subsidiary.

        (d)  Subject  to the  clause  in  Article  VI of the  General  Agreement
entitled SCOPE OF AGREEMENT,  if AT&T or a controlled  United States  subsidiary
cancels any order, terminates any service, or receives any refund or credit from
NCR due to delays,  lateness (except for delays or lateness due to force majeure
conditions under the General Agreement), breach of warranty, breach of



<PAGE>

contract,  or  nonperformance  by NCR,  the  amount of the  Commitment  shall be
reduced  by the  amount  (included  any  related  purchases)  that  AT&T or such
affected subsidiary would have spent but for such event.

        (e) AT&T's spending  forecast in effect as of January 1, 1997 sets forth
AT&T's initial  estimate of its aggregate  spending for  information  technology
products and services  obtained from all sources  during the  Purchasing  Period
("Initial  Forecasted  Spending").  If, after the date of this  Agreement,  AT&T
adopts a smaller  aggregate  budget  for such  information  technology  spending
during the Purchasing  Period ("Revised  Forecasted  Spending"),  the Commitment
will be proportionately reduced according to the following formula:


- --                                        --   --               --
|Revised Forecasted Spending | |other adjustments|
|---------------------------
X $350 million| - | to Commitment | = adjusted |Initial  Forecasted Spending | |
per Section 7 | Commitment
- --                                        --   --               --

Notwithstanding   the  foregoing,   if  AT&T's  actual  aggregate  spending  for
information  technology  Products  and  Services  during the  Purchasing  Period
("Actual Spending") is less than Initial Forecasted Spending but exceeds Revised
Forecasted Spending,  Actual Spending will be used instead of Revised Forecasted
Spending in the above formula; provided, however, that for purposes of the above
formula,  the ratio of  Revised  Forecasted  Spending  (or Actual  Spending,  if
applicable)  to  Initial  Forecasted  Spending  shall not  exceed  1/1,  and the
adjustment  to  Commitment  described  in this  Section 7(e) shall not under any
circumstances be used to increase the amount of the Commitment.  For purposes of
this Section 7(e), Revised Forecasted Spending and Actual Spending shall exclude
spending  by (or on  behalf  of) any  AT&T  business  organization  that was not
included in the projection of Initial Forecasted Spending.

        (f) NCR acknowledges  that AT&T's ability to fulfill the Commitment will
be impaired if companies engaged in equipment  financing or leasing  ("Financing
Companies")  are  unwilling to provide  financing or leasing for NCR products on
terms as favorable as those offered for comparable  non-NCR products  ("Standard
Financing Terms").  Accordingly,  the Commitment shall be adjusted in accordance
with this Section 7(f) if any of the following events occurs:

        (i) If any  Financing  Company  selected  by a  customer
of AT&T or its
        controlled United States subsidiaries (or by its agent,
including AT&T's
        AT&T Solutions business unit) refuses to provide financing
or leasing to
        or for that  customer  for any  Eligible  Product on
Standard  Financing
        Terms,


<PAGE>


        and if such refusal persists after NCR has had a
reasonable  opportunity
        to address the reasons therefor,  the Commitment shall be
reduced by the
        dollar amount of the purchases AT&T  represents  would
have been made by
        or for such customer from NCR (including related
purchases) but for such
        refusal.

        (ii) If any four  Major  Financing  Companies  (as
defined  in  Section
        7(f)(iv))  selected by a dealer or distributor or reseller
(or by any of
        their  respective  agents)  or  AT&T  or its  controlled
United  States
        subsidiary refuse to provide financing or leasing to such
person for any
        Eligible  Product  on  Standard  Financing  Terms,  and if
such  refusal
        persists  after NCR has had a reasonable  opportunity
(not to exceed 90
        days) to address the reasons  therefor,  the Commitment
shall be reduced
        by the dollar amount of the purchases  AT&T  represents
would have been
        made by or for such dealer,  distributor or reseller from
NCR (including
        related purchases) but for such refusal.

        (iii) If any four Major Financing  Companies selected by
AT&T (including
        its controlled United States  subsidiaries)  refuse to
provide financing
        or  leasing  to AT&T or such  subsidiary  for any
Eligible  Product  on
        Standard Financing Terms, and if such refusal persists
after NCR has had
        a reasonable  opportunity (not to exceed 90 days) to
address the reasons
        therefor, AT&T may, at its option,  terminate the
Commitment at any time
        by  giving  written  notice  to NCR.  Upon  any  such
termination,  the
        Commitment shall be extinguished,  AT&T's obligation
thereunder shall be
        deemed entirely fulfilled, and the Purchasing Period shall
terminate.

        (iv) As used in this Section 7(f), the term "Major
Financing  Companies"
        includes the five  Financing  Companies  having the
greatest  aggregate
        dollar  volume of current  financing or leasing
transactions  with AT&T
        (including its controlled  United States  subsidiaries),
plus all other
        Financing Companies that are among the 20 largest Financing Companies.

8.      MONITORING AND REPORTING.

        (a) At least once each  calendar  quarter,  NCR shall  furnish to AT&T a
written  report of  Commitment  fulfilled by AT&T's  direct  purchases  from NCR
during the  preceding  quarter.  Each such report  shall  include a breakdown of
Eligible  Products  purchased,  by  product  and  service  category,  and  shall
summarize the cumulative status of Commitment fulfillment.



<PAGE>

        (b) At least once each  calendar  quarter,  AT&T shall  furnish to NCR a
written  report of Eligible  Products  purchased  by AT&T from NCR VARs and ISVs
both  domestic and  international  during the preceding  quarter.  AT&T's report
shall also identify any  adjustments  to Commitment  claimed by AT&T pursuant to
Section 7 as a result  of events  that  became  known to AT&T in that  preceding
quarter.

        (c) Within 90 days after the end of each calendar year of the Purchasing
Period, NCR and AT&T shall enter into a written agreement documenting the amount
of Commitment  fulfilled  achieved during that year and the remaining balance of
unfulfilled Commitment.  If the parties are unable to reach agreement during the
90-day  interval,  either  party may  initiate  alternative  dispute  resolution
pursuant to Article V of the General Agreement.

        (d) Each party  shall  afford the other  party  such  documentation  and
limited audit rights as may be reasonably  necessary to enable  verification  of
the information reported pursuant to this Section 8.

9.      NONFULFILLMENT OF COMMITMENT.

        (a) If AT&T has failed to fulfill its  Commitment  by December 31, 1999,
and elects to extend the  Purchasing  Period until December 31, 2000 pursuant to
Section 2(b), the remaining  unfulfilled balance of the Commitment as of January
1, 2000 shall be increased by 5 percent, according to the following formulas:

               | adjustments to  |
               |   Commitment    |   |  Commitment    |
|unfulfilled |
$350 million - |  per Section 7  | - |  fulfillment   | = |
Commitment |
               |through 12/31/99 |   |through 12/31/99|   |as of
1/1/00|


               |  unfulfilled |
               |  Commitment  | X 1.05 = Year 2000 Increased
Commitment
               | as of 1/1/00 |

        (b) If AT&T has failed to fulfill its  Increased  Commitment by December
31, 2000 and elects to extend the Purchasing Period until
December  31, 2001
pursuant to Section 2(b), the remaining unfulfilled balance of the
Increased



<PAGE>


Commitment as of January 1, 2001 shall be increased by 10 percent,  according to
the following formulas:

                     | adjustments to |
                     |   Year 2000    |
        Year 2000    |   Commitment   |   |   Year 2000    |   |

        Commitment - | per Section 7  | - |   Commitment   | = |
Commitment  |
                     |  from 1/01/00  |   |   fulfillment  |   |
as of 1/1/01|
                     |through 12/31/00|   |through 12/31/00|



        |unfulfilled |
        | Commitment | X 1.10 = Year 2001 Increased Commitment
        |as of 1/1/01|

        (c) At the conclusion of the Purchasing Period (as extended, should AT&T
so elect  pursuant  to  Section  2(b)),  if AT&T has not  fully  discharged  the
Commitment,  NCR shall,  in January  2000 (or in  January  2001 or 2002,  if the

AGENTS) BE HEREUNDER
LIABLE  TO THE OTHER  PARTY  FOR ANY  INDIRECT,  INCIDENTAL,
CONSEQUENTIAL,  OR
PUNITIVE DAMAGES (EVEN IF MADE AWARE OF THE POSSIBILITY OF SUCH
DAMAGES), OR FOR
LOSS OF PROFITS OR REVENUE.

        (g) THE  LIMITATIONS OF REMEDIES AND  LIABILITIES  SET
FORTH IN SECTIONS
9(e)  THROUGH  9(f) SHALL  APPLY  REGARDLESS  OF THE FORM OF
ACTION,  WHETHER IN
CONTRACT, TORT (INCLUDING NEGLIGENCE,  WHETHER ACTIVE OR PASSIVE),
OR OTHERWISE,
AND SHALL SURVIVE THE EXPIRATION OR TERMINATION OF THIS AGREEMENT.

10.  TERMS  AND  CONDITIONS  GOVERNING  PURCHASES.  Contemporaneously  with  the
execution of this Agreement, AT&T and NCR are entering into a General Procedures
Agreement  (hereinabove  and below referred to as the "General  Agreement"),  to
establish  terms and  conditions  governing  AT&T's  purchases  of products  and
services from NCR. In the event of any conflict between the terms and conditions
of this Agreement and those in the General  Agreement,  the terms and conditions
of this Agreement shall prevail and control.

11.     COUNTERPARTS; ENTIRE AGREEMENT; CORPORATE POWER.
(a) This Agreement may be executed in one or more counterparts,
all of which
shall be considered one and the same agreement, and shall become
effective when
one or more counterparts have been signed by each of the parties
and delivered
to the other party.

        (b) This  Agreement,  including the documents  incorporated by reference
herein,  together  with the General  Agreement,  contains  the entire  agreement
between the parties with respect to the subject  matter  hereof,  and supersedes
all previous agreements,  negotiations,  discussions,  writings, understandings,
commitments, and conversations with respect to such subject matter.

        (c) AT&T  represents  on behalf of itself and each of its  subsidiaries,
and NCR represents on behalf of itself and each of its subsidiaries, as follows:

        (i) each such  person has the  requisite  corporate  or
other  power and
        authority and has taken all corporate or other action
necessary in order
        to execute,  deliver,  and perform this  Agreement and to
consummate the
        transactions contemplated hereby; and



<PAGE>

        (ii) this  Agreement  has been duly  executed  and
delivered  by it and
        constitutes  a  valid  and  binding   agreement  of  it
enforceable  in
        accordance with the terms thereof.

12.     SUCCESSOR COMPANIES.  The parties recognize that the
ownership and
organization of their respective companies may change during the
term of this
Agreement. Accordingly, the parties agree as follows:

        (a) If a third party (including without limitation any present or future
NCR parent or affiliate)  succeeds to any substantial portion of the business of
NCR with respect to any Eligible  Product ("NCR Successor  Company"),  NCR shall
use reasonable  efforts to continue  making such Eligible  Product  available to
AT&T under this Agreement and the General Agreement.  These efforts may include,
at NCR's  option,  arranging  for NCR to resell  the  Eligible  Product to AT&T.
Alternatively,  NCR may obtain the NCR Successor  Company's agreement to join in
the terms and  conditions  of this  Agreement and of the General  Agreement,  in
which event the parties  shall  promptly  amend the  definitions  of NCR in this
Agreement and in the General Agreement to include the NCR Successor Company.  If
NCR is unable or unwilling to continue making the Eligible Product  available to
AT&T under this Agreement and the General Agreement, NCR shall be deemed to have
failed to meet AT&T's needs for the Eligible  Product,  and any  resulting  AT&T
purchases  from   Alternative  IT  Suppliers  shall  reduce  the  Commitment  in
accordance with Section 7(b).

        (b) If AT&T  notifies  NCR that any third  party has  succeeded  or will
succeed to any  substantial  portion of the  business of AT&T  ("AT&T  Successor
Company"), the parties shall take the following steps:

        (i) If the AT&T Successor Company directly or indirectly
controls AT&T,
        or if the AT&T Successor Company and AT&T are under
substantial  common
        control,  and if the AT&T Successor  Company's  spending
for Information
        Technology  products  and  services is included  in the
aggregate  AT&T
        budget for information  technology  spending  described in
Section 7(e),
        the parties  (subject to the concurrence of the AT&T
Successor  Company)
        will amend the  definitions of AT&T in this Agreement and
in the General
        Agreement to include the AT&T Successor  Company.  Such
amendments will
        enable the AT&T Successor Company to purchase from NCR
under the prices,
        terms,  and conditions of this  Agreement and of the
General  Agreement,
        and all such  purchases  by the AT&T  Successor  Company
will be deemed
        purchases by AT&T for purposes of Commitment fulfillment.



<PAGE>



     (ii) If the AT&T  Successor  Company is an  affiliate  of
AT&T but does not
     control and is not under common control with AT&T, or if the
AT&T Successor
     Company's spending for information  technology products and
services is not
     included in the aggregate AT&T budget for information
technology  spending
     described  in Section  7(e),  NCR and AT&T (in  consultation
with the AT&T
     Successor  Company) will mutually determine whether to amend
this Agreement
     and the General Agreement in the manner described in Section
12(b)(i).  If
     NCR and AT&T fail to agree upon such amendments within 60 days after AT&T's
     notice, AT&T may, at its option,  reduce the Commitment
pursuant to Section
     7(e) by excluding all future  purchases by the AT&T
Successor  Company from
     AT&T's Revised Forecasted Spending and AT&T's Actual Spending.

     (iii) If the AT&T Successor Company is neither a parent nor
an affiliate of
     AT&T,  AT&T may, at its option,  reduce the Commitment
pursuant to Section
     7(e) by excluding all future  purchases by the AT&T
Successor  Company from
     AT&T's Revised Forecasted Spending and AT&T's Actual Spending.

     (iv) If AT&T  elects to reduce the  Commitment  as
permitted  by  Sections
     12(b)(ii)  or  (iii),  NCR will  have no  obligation  to
make  the  pricing
     described in this Agreement  available to the AT&T Successor
Company,  and
     future  purchases  by the AT&T  Successor  Company  will not
count  toward
     Commitment fulfillment.

13.  MISCELLANEOUS. The provisions of Article 8 of the
Distribution Agreement
are specifically incorporated herein by reference.

                  to  a  pension),  if   the  period  after  the
last  day  the
                  Participant  was  on  the  active  payroll  and
prior  to the
                  Participant's sixty-fifth birthday  had been
included  in  the
                  Participant's  term  of  employment  as  of
the  end  of  the
                  applicable averaging  period under the Pension
Plan,  plus (b)
                  the monthly  pension the Participant  would have
been entitled
                  to receive commencing  at age 65 under the AT&T
Non-Qualified
                  Pension Plan (as in effect on the last day the
Participant was
                  on  the  active  payroll, but  ignoring  any
minimum  service
                  requirements  for  eligibility to  a pension),
if the  period
                  after the last day the Participant  was on the
active  payroll
                  and prior to the Participant's sixty-fifth
birthday  had been
                  included  in the  Participant's  Term of
Employment as of  the
                  end  of  the  applicable  averaging   period
under  the  AT&T
                  Non-Qualified  Pension Plan, reduced by any
amounts  described
                  in  Section 2.05(c) that are attributable  to
the  period for
                  which benefits are provided under this paragraph.

2.05.    (a)      The  Disability  allowance  determined  for any
period  under
                  Section 2.02  shall  be  reduced  by the  sum of
the following
                  benefits  received by  the Participant  which
are attributable
                  to the period for which such disability
allowance is provided:
                  a service  pension,  deferred  vested  pension,

Disability  Benefit
                  Plan, any Workers' Compensation  Benefit, plus
any  comparable
                  benefits   provided   under  the  plans  or
programs  of  any
                  Successor Plan Sponsor and any other benefit
payments required
                  by law on account of the  Participant's
disability.  However,
                  no reduction shall be made on account of any
pension under the
                  Pension Plan at a rate greater than  the rate of
such  pension
                  on  the  date  the  Participant  first
received  such pension
                  after his or her disability, and no  reduction
shall  be made
                  on  account  of any  pension  under  the AT&T
Non-Qualified
                  Pension Plan, the  AT&T Excess Benefit and
Compensation  Plan,
                  or the AT&T Mid-Career Pension Plan at a rate
greater than the
                  rate of such pension, including adjustments if
any to  reflect
                  post-retirement incentive awards to the
Participant  under the
                  Short  Term  Plan, as  of  the  first  date
the   Participant
                  was  entitled  to  receive  such  pension
after  his  or her
                  disability.

         (b)      The  disability  allowance  determined  for
any  period under
                  Section 2.03  shall  be  reduced  by  the sum of
the following
                  benefits  received by  the Participant  which
are attributable
                  to the period for which such disability
allowance is provided:
                  a  service  pension,  deferred  vested  pension
or  disability
                  pension under  the  Pension  Plan,  a  pension
under the AT&T
                  Excess Benefit and Compensation Plan, a pension
under the AT&T
                  Non-Qualified   Pension  Plan,  a   pension

                  Mid-Career Pension Plan, an accident  disability
benefit under
                  the  Disability   Benefit Plan, any  other
retirement  income
                  payments from the Participant's Participating
Company  or any
                  Successor Plan Sponsor,  any  Workers'
Compensation  Benefit,
                  plus  any  Social  Security  Insurance
Benefit.  However,  no
                  reduction  shall be  made on account of any
pension  under the
                  Pension Plan at  a rate  greater than the rate
of such pension
                  on the date the Participant first received such
pension  after
                  his  or  her  disability, and  no  reduction
shall be made on
                  account of any pension under the  AT&T
Non-Qualified  Pension
                  Plan,  the   AT&T  Excess  Benefit and
Compensation  Plan, or
                  under  the  AT&T  Mid-Career  Pension  Plan at a
rate  greater
                  than the rate of such pension, including
adjustments if any to
                  reflect  post-retirement incentive  awards to
the  Participant
                  under  the  Short  Term  Plan,  as  of  the
first  date   the
                  Participant  was  entitled to receive  such
pension  after his
                  or her disability, and no  reduction  shall be
made on account
                  of any Social Security  Benefit at  a  rate
greater  than the
                  rate which the  Participant  would have first
been eligible to
                  receive  after  his  or  her  disability  and
as  if no other
                  members of  his or  her family  were  eligible
for any Social
                  Security Benefit. Furthermore,  the Board of
Directors  of the
                  Company,  in   its  discretion,  may   reduce
the  disability
                  allowance by the amount of  outside
compensation  or earnings
                  of     the    Participant   for   work
performed   by    the
                  Participant  during   the  period for  which
such  disability
                  allowance is provided.

         (c)      The  disability  allowance  determined  for
any  period under
                  Section 2.04  shall  be  reduced  by  the sum of
the following
                  benefits  received by  the Participant  which
are attributable
                  to the period for which such disability
allowance is provided:
                  a service   pension,  deferred  vested  pension
or disability
                  pension  under  the  Pension  Plan, a  pension
under the AT&T
                  Excess  Benefit  and  Compensation  Plan, a
pension  under the
                  AT&T  Non-Qualified  Pension  Plan, a pension
under the  AT&T
                  Mid-Career Pension Plan, an accident  disability
benefit under
                  the  Disability  Benefit Plan,  any  other
retirement  income
                  payments  from  the  Participant's
Participating  Company  or
                  any Successor  Plan  Sponsor, plus  any
Workers'  Compensation
                  Benefit. However, no reduction shall be made on
account of any
                  pension  under the Pension  Plan at a rate
greater  than  the
                  rate  of  such  pension  on  the  date the
Participant  first
                  received  such  pension  after  his or her
disability, and no
                  reduction  shall be  made on account of any
pension  under the
                  AT&T  Non-Qualified  Pension Plan, the AT&T
Excess Benefit and
                  Compensation  Plan, or under the AT&T
Mid-Career  Pension Plan
                  at a rate greater than the rate  of  such
pension,  including
                  adjustments if any to reflect post-retirement
incentive awards
                  to the Participant  under the Short Term Plan,
as of the first
                  date  the  Participant was entitled  to  receive
such  pension
                          after his or her disability.

2.06.    For purposes of Sections  2.01(a) and 2.01(b), the
measurement of time
         following the onset of a physical or mental  impairment
shall coincide
         with the measurement of time used to calculate  periods
of Sickness and
         Accident Disability Benefits under  Sections 4 and 5 of
the  Disability
         Benefit Plan. Successive periods of physical or mental
impairment shall
         be  counted  together  in  computing  the  periods
during  which   the
         Participant  shall be entitled to the benefits  provided
under Sections
         2.02 and 2.03, except that any disability absence after
the Participant
         has been  continuously  engaged in the performance of
duty for thirteen
         weeks  shall  be  considered  to  commence  a new period
of physical or
         mental  impairment  under Section  2.01 (a),  so that
such  Participant
         shall be entitled during such new period to the benefits
provided under
         Section 2.02.

2.07.    With respect to a  Participant  not subject to mandatory
retirement at
         age 65 under the Age  Discrimination in Employment Act
(29 U.S.C. 631),
         the period of  eligibility  for the  disability
allowance  provided in
         Section 2.03 and the period of eligibility for the
disability allowance
         provided  in Section  2.04,  shall be the period
described  in Section
         2.03, and the period described in Section 2.04,
respectively,  or such
         other period as is required under the Age  Discrimination
in Employment
         Act or under any applicable  governing  regulations or
interpretations
         thereunder.

3.01.    A Participant  described in Section  1.10(a)  whose term
of  employment
         has  been  five  years  or  more and  is  not disabled,
who terminates
         employment  on   or  after  his  or  her  sixty-second
birthday,  or a
         Participant described  in Section 1.10(b)  who is
retired  on a service
         pension under the Pension Plan, shall be eligible to
receive a  monthly
         minimum  retirement  benefit  equal to one and
one-quarter  percent of
         Participant's annual basic pay, as defined in Section
1.04, on the last
         day the  Participant  was on the active  payroll reduced
by the sum of
         the  following   benefits  received  by   the
Participant  which   are
         attributable  to the  period for  which  benefits  are
provided  under
         this  Article 3: a  service  pension or  deferred  vested
pension under
         the  Pension Plan,  a  pension  under  the  AT&T
Excess   Benefit  and
         Compensation Plan, a pension under the AT&T Non-Qualified

         a pension under the AT&T  Mid-Career  Pension Plan, and
by  any  other
         retirement  income  payments  received  by  the
Participant  from  his
         or her Participating Company or from a Successor Plan
Sponsor. However,
         no reduction shall be made on account of any pension
under the Pension
         Plan at a rate  greater  than the rate of such  pension
on the date the
         Participant  first  received  such pension after his or
her  retirement
         or other  termination of employment, and no reduction
shall be made on
         account  of  any  pension under the AT&T  Non-Qualified
Pension  Plan,
         the  AT&T Excess  Benefit and  Compensation  Plan, or
under  the  AT&T
         Mid-Career  Pension  Plan  at a  rate greater  than the
rate  of  such
         pension,  including   adjustments  if any   to reflect
post-retirement
         incentive awards   to the  Participant  under the Short
Term Plan,  as
         of the first date the Participant was entitled  to
receive such pension
         after his or her retirement or other termination of
employment.

3.02.    If an amendment to the Pension  Plan  effective on or
after  January 1,
         1988,  provides for an increase in the service  pensions
of  previously
         retired  employees,  then a Participant's  minimum
retirement  benefit
         shall be increased pursuant to the same terms and
conditions as are set
         forth in such Pension Plan amendment.

4.01.     In the  event  of the  death of a  Participant,  who is
described  in
          Section 1.10(c), the surviving lawful spouse of such
Participant shall
          be eligible to receive a monthly  benefit equal to one

          percent of the  Participant's  annual basic pay, as
defined in Section

payroll prior
          to his or her  death  reduced  by the  sum of the
following  benefits
          received by the  Participant's  surviving  lawful spouse
on account of
          the death of the Participant and which are  attributable
to the period
          for which  benefits are provided  under this Article 4:
an annuitant's
          pension   under  the  Pension  Plan,  an  annuity
under  the  Insured
          Annuitant's Plan, an annuitant's pension under the AT&T
Excess Benefit
          and  Compensation   Plan,  an  annuitant's   pension
under  the  AT&T
          Non-Qualified  Pension  Plan and any other  lifetime
payments to such
          surviving lawful spouse from the Participant's
Participating  Company
          or from any Successor  Plan Sponsor.  However,  no
reduction  shall be
          made on account of an  annuitant's  pension under the
Pension Plan, or
          on  account of an  annuitant's  pension  under the AT&T
Non-Qualified
          Pension Plan or on account of an  annuitant's  pension
under the AT&T
          Excess  Benefit and  Compensation  Plan,  or on account
of any annuity
          under the Insured Annuitant's Plan at a rate greater
than (1) the rate
          of such  pension or annuity  on the date such  pension
or annuity  was
          first payable in the case of the death of a Participant
who is on the
          active  payroll or (2) the rate of such pension or
annuity on the date
          such  pension  or  annuity  first  would  have  been
payable  had the
          Participant  died on the day after the last day the
Participant was on
          the active  payroll in the case of the death of a
Participant  who is
          not on the active payroll.

4.02.    Notwithstanding  any  provision  of Section 4.01 to the
contrary,  the
         surviving  lawful  spouse of a  Participant  shall not
be  eligible  to
         receive  benefits  under this Article 4 if, prior to the
Participant's
         death,  he could  have  elected  under  the  Pension
Plan or under any
         predecessor  pension  plan  maintained  by a
Participating  Company to
         receive  a  reduced  pension  for his or her life in
order to  provide
         thereafter an annuity for the life of his or her lawful
spouse,  but he
         declined to make such an election.

4.03.    If an amendment to the Pension  Plan  effective on or
after  January 1,
         1988,  provides for an increase in the survivor annuities
payable under
         said Plan, then the Surviving Spouse Benefit payable
under Section 4.01
         above shall be increased  pursuant to the same terms and
conditions as
         are set  forth in such  Pension  Plan  amendment,
except  that no such
         increase  shall  apply to the  Surviving  Spouse
Benefit  related to a
         deceased Participant who had not terminated employment or
died prior to
         the effective date of such amendment.

                                 DEATH BENEFITS

5.01.    Upon the death of a Participant described in Section
1.10(d) whose last
         day on the active payroll occurred on or after January 1,
1987, and who
         has not retired on a service pension or a disability
pension under the
         Pension Plan, a death benefit in the amount of the
Participant's annual
         base salary rate in effect on the last day said
Participant was on the
         active payroll shall be paid to one or more of the
beneficiaries listed
         in  Section  5.02  below  as  determined  by the
Committee,  provided,
         however,  that such  death  benefit  shall be reduced by
the sum of any
         death  benefit  paid under  Section 5 of the Pension Plan
on account of
         the Participant's death.

5.02.    The persons who may be the beneficiaries of the death

mentally  incapable of
         self-support)  who  were  being  supported  in  whole or
in part by the
         deceased at his or her death,  or a dependent  parent or
parents living
         with  the  deceased  at the time of his or her  death or
in a  separate
         household in the vicinity of the deceased and provided by
him.

5.03.    If the  Participant  is not  survived  by any person
listed in Section
         5.02,  a death  benefit up to the maximum  amount shown

         above may be payable, at the discretion of the
Committee,  to any other
         dependent  relative  receiving or entitled to receive
support from the
         deceased; if no such dependent relative survives the
deceased, no death
         benefit will be payable under this Plan.

                                SOURCE OF PAYMENT

6.01.    Source of Payments.

         AT&T may  establish a trust to hold  assets to be used to
make  benefit
         payments  under the terms of this  Plan,  provided  such
trust does not
         cause the Plan to be  "funded"  within  the  meaning  of
ERISA.  Funds
         invested  hereunder  shall, for purposes of this Plan, be
considered to
         be  part of the  general  assets  of the  Participating
Company  which
         invested the funds,  and no  Participant,  beneficiary or
lawful spouse
         shall have any  interest  or right in such funds.  To the
extent  trust
         assets are  available,  they may be used to pay benefits
arising under
         this Plan and all costs,  charges and expenses relating
thereto. To the
         extent  that the funds held in the trust are
insufficient  to pay such
         benefits,   costs,  charges  and  expenses,  AT&T  or
the  responsible
         Participating  Company  shall pay such  benefits,
costs,  charges  and
         expenses from its general  assets.  In addition,  AT&T
may, in its sole
         discretion,  direct  that  payments  required  under
this  Plan to any
         Participant or surviving lawful spouse be made through
the purchase and
         distribution of one or more nontransferable  annuity
contracts or cause
         the  trustee  of the trust to  purchase  and  distribute
such  annuity
         contracts.  Any such purchase and  distribution of an
annuity  contract
         shall be a full and complete  discharge  of the Plan's,
AT&T's and the
         Participating  Companies'  liability for payments assumed
by the issuer
         of the annuity  contract.  Further,  the Senior Vice
President,  Human
         Resources,  may  determine,  in  his  or her  sole
discretion,  to pay
         additional  sums to any  Senior  Manager,  from the
Company's  general
         assets or from the trust,  if any, to reimburse the
Senior  Manager for
         additional  federal and state income taxes  estimated to
be incurred by
         reason of the  distribution of any such annuity
contracts.  The Senior
         Vice  President,  Human  Resources  shall  establish a
methodology  or
         methodologies  for determining the amount of such
additional  sums. The
         methodology  or  methodologies  selected shall be those
that the Senior
         Vice  President,  Human  Resources  determines,  in  his
or  her  sole
         discretion,  to be the most effective and
administratively feasible for
         the purpose of  producing  after tax  periodic  benefit
payments  that
         approximate  the after tax periodic  benefit  payments
that would have
         been received by Participants in the absence of the
distribution of the
         annuity contract.

6.02.    Unfunded Status.

         The Plan at all times shall be entirely  unfunded  for
purposes of the
         Internal  Revenue Code of 1986, and ERISA,  and,  except
as provided in
         Section  6.01,  no provision  shall at any time be made
with respect to
         segregating  any assets of a  Participating  Company for
payment of any
         benefits  hereunder.  Funds invested  hereunder  shall
continue for all
         purposes to be part of the general assets of the
Participating  Company
         which  invested the funds.  The Plan  constitutes a mere
promise by the
         Participating  Company to make  payments,  if any,  in
the  future.  No
         Participant,  spouse,  beneficiary  or any other  person
shall have any
         interest in any particular assets of a Participating
Company by reason
         of the right to receive a benefit  under the Plan and to
the extent the
         Participant,  surviving lawful spouse,  beneficiary or
any other person
         acquires a right to receive  benefits under this Plan,
such right shall
         be no greater  than the right of any  unsecured  general
creditor of a
         Participating Company.

7.01.    Administration and Authorities.

         The Plan shall be  administered  by the  Company and it
shall have full
         discretionary  authority  to  manage  and  control  the
operation  and
         administration of the Plan, including the power to
interpret provisions
         of  the  Plan,  make  determinations  of  fact,
promulgate  rules  and
         regulations, determine benefit eligibility of individual
and classes of
         Participants,   delegate  its  powers  and  duties
hereunder  to  the
         Committee, the Administrator or others and take such
other action as it
         shall find necessary and appropriate to implement the
provisions of the
         Plan.  The  Committee  and  the  Administrator  may
retain  attorneys,
         consultants,  accountants or other persons (who may be
employees of the
         Company or an Affiliated  Corporation)  to render advice
and assistance
         and may delegate any of the authorities conferred on it
to such persons
         as it shall  determine to be appropriate to effect the
discharge of its
         duties hereunder.  The Company, the Affiliated
Corporations and any of
         their officers and employees shall be entitled to rely
upon the advice,
         opinions,  and determinations of any such persons.  Any
exercise of the
         authorities  set forth in this  Section,  whether by the
Company,  the
         Committee or its  Delegate,  or the  Administrator,
shall be final and
         binding upon the Company, its Affiliated Corporations,
their officers,
         directors and affected Participants and beneficiaries.

7.02.    Committee.

         The Company has delegated to the Committee  authority to
make the final
         determination  to grant or deny claims for benefits under
the Plan with
         respect to Participants and to authorize disbursements
according to the
         terms of the Plan.

7.03.    Indemnification.

         No member of the Board or the Committee or the
Administrator  shall be
         personally  liable  by  reason  of any  contract  or
other  instrument
         executed  by  such  individual  on his or her  behalf  or
in his or her
         capacity as a member of the Board,  Committee or the
Administrator nor
         for any  mistake  of  judgment  made  in good  faith,
and  AT&T  shall
         indemnify and hold  harmless  each member of the Board,
each member of
         the Committee,  the Administrator and each other
employee,  officer, or
         director of AT&T or any Participating Company to whom any
duty or power
         relating to the  administration  or  interpretation  of
the Plan may be
         allocated  or  delegated,   against  any  cost  or
expense  (including
         attorneys' fees) or liability  (including any sum paid in
settlement of
         a claim)  arising out of any act or omission to act in
connection  with
         the Plan unless arising out of such person's own fraud or
bad faith.

7.04.    Benefit Claims and Appeals.

         (a)      Benefit  Claims.  All claims for benefit
payments  under  the
                  Plan shall be  submitted in writing  by
Participants  to  the
                  person  designated  by  the  Company  to  make
determinations
                  as to eligibility  for benefits under the Plan
and such person
                  shall notify the  Participant in writing  within
90 days after
                  receipt as to whether  the claim has been
granted or  denied.
                  This  period  may be extended for up to an
additional 90 days
                  in  unusual  cases   provided  that written
notice  of  the
                  extension is furnished to the claimant  prior to
the
                  commencement  of the  extension.  In    the
event the claim is
                  denied,  such notice  shall (i) set forth the
specific
                  reason or reasons for denial, (ii) make
reference to the
                  pertinent  Plan  provisions on which the denial
is based,
                  (iii)  describe  any  additional  material  or
information
                  necessary  before the  Participant's request may
be acted upon
                  favorably,  and (iv) explain the  procedure  for
appealing the
                  adverse determination.

         (b)      Benefit  Appeals.  A Participant  whose claim
for benefits has
                  been denied may, within 60 days of   receipt of
any  adverse
                  benefit  determination,  appeal  such denial to
the Committee.
                  All appeals shall be in the form of a  written
statement  and
                  shall (i) set forth all of the reasons in
support of favorable
                  action on the appeal,  (ii)  identify    those
provisions  of
                  the Plan  upon  which  the  claimant  is
relying,  and (iii)
                  include  copies  of  any other  documents or
materials  which
                  may support  favorable  consideration  of   the
claim.   The
                  Committee shall decide the issues presented
within
                  60 days after receipt of such request,  but this
period may be
                  extended  for up to an  additional  60 days in
unusual  cases
                  provided that written  notice of the extension
is furnished to
                  the claimant prior to the  commencement of the
extension.  The
                  decision  of the  Committee  shall be set
forth  in  writing,
                  include specific reasons for the decision,
refer to pertinent
                  Plan  provisions on which the decision is
based,  and shall be
                  final and binding on all persons affected
thereby.

                       Adoption, Amendment and Termination


8.01.    Adoption of Plan.

         Any Affiliated  Corporation that  participates in the
Pension Plan may,
         with the consent of the  Committee,  elect to
participate in the Plan.
         Such Affiliated  Corporation shall become a Participating
Company as of
         the date  specified by the  Committee in its  resolution
approving the
         participation of the Affiliated Corporation in the Plan.

8.02.    Amendment and Termination.

         AT&T is the Sponsor of the Plan and the Board or its
delegate, may from
         time to time  amend,  modify  or  change  the Plan as set
forth in this
         document, and the Board or its delegate (acting pursuant
to the Board's
         delegations  of authority then in effect) may terminate
the Plan at any
         time. Plan amendments may include,  but are not limited
to, elimination
         or reduction in the level or type of benefits  provided
to any class or
         classes or Participants,  surviving lawful spouses and
beneficiaries).
         Any and all Plan  amendments  may be made  without  the
consent of any
         employee,  Participant,  spouse  or  beneficiary.
Notwithstanding  the
         foregoing,  the exercise of the power to amend, modify or
terminate the
         Plan shall be subject to the  limitations  described in
paragraphs  (a)
         and (b) below.

         (a)      Such amendment,  modification or termination
shall not affect
                  the rights of any  Participant  or  surviving
lawful  spouse,
                  without his or her consent,  to any benefit
under the Plan to
                  which such  Participant  or surviving  lawful
spouse may have
                  previously become entitled as a result of
disability, death or
                  termination of employment which occurred prior
to the later of
                  the adoption date or the effective  date of
such  amendment or
                  termination.

         (b)      Such  amendment,  modification  or termination
shall not
                  affect the rights of any Participant or  his or
her surviving
                  lawful spouse,  without his or her consent,  to
any future
                  benefits payable   under  Article 3 or Article
4,  provided
                  that,  prior to the later of the  adoption  date
or the
                  effective date of such amendments or
termination,  such
                  participant  either (i) had satisfied the
requirements  for
                  eligibility  for  the  benefits   described  in
Article  3,
                  other  than  the termination  of  employment
requirement,  or
                  (ii) had begun to  receive a  disability
allowance  under
                  Article 2. For  purpose of  determining  a
spouse's  benefit,
                  it shall be assumed  that a     Participant  who
is  receiving
                  a disability  allowance  as of the later of the
adoption
                  date or  effective  date of such  amendment
will  continue to
                  receive  said  allowance  until his or her
death.  The annual
                  basic pay used to compute such future  benefits
under
                  Article 3 or Article 4  shall be the
Participant's  highest
                  annual  basic pay as  described  in Section 1.04
on any day
                  during the term of his or her  employment
completed  prior to
                  the later of the adoption  date or the
effective  date of such
                  amendments  or  termination  as if the
Participant  had
                  terminated  employment on that day.

8.03.    Sale, Spin-Off, or Other Disposition of Participating
Company.

         (a)      Subject to Section 8.02 of this Plan, in the
event AT&T sells,
                  spins off, or otherwise disposes of an
Affiliated Corporation,
                  or  disposes of all or  substantially  all of
the assets of an
                  Affiliated  Corporation  such  that  one or
more  Participants
                  terminate  employment for the purposes of
accepting employment
                  with  the  purchaser  of such  stock  or
assets,  any  person
                  employed by such  Affiliated  Corporation  who
ceases to be an
                  employee  of the  Company or an  Affiliated
Corporation  as a
                  result of the sale,  spin-off,  or disposition
shall be deemed
                  to have  terminated his or her employment with a
Participating
                  Company for all relevant purposes under this Plan.

         (b)      Notwithstanding   the   foregoing   provisions
of   this
                  Section 8.03,  and subject to Section 8.02 of
this Plan, if
                  the sale,  spin-off,  or other  disposition of
the stock or
                  assets of an Affiliated Corporation  is to a
Successor  Plan
                  Sponsor with the effect that a  Participant  is
or becomes a
                  Transition  Participant,  the  Successor  Plan
Sponsor  shall
                  be solely liable for the payment of  the pension
and death
                  benefits  described in this Plan,  and the
entitlement  of
                  the Transition  Participant  or his or her
surviving  lawful
                  spouse or  beneficiary  to benefits  under this
Plan  shall
                  terminate.  A Transition  Participant  shall not
be considered
                  to have  terminated  his or  her employment with
AT&T or a
                  Participating Company for any purpose under this Plan.

                                    ARTICLE 9
                               GENERAL PROVISIONS


9.01.    Effective Date.

         This  Plan was first  adopted  with  effect  on March
17,  1976 and is
         amended and restated  effective  January 1, 1995.  The
amendments  set
         forth herein shall be effective with respect to
Participants  who first
         become  eligible  for benefits  under this Plan on or
after  January 1,
         1995.

9.02.    Assignment of Benefits.

         The benefits payable  hereunder or the right to receive
future benefits
         under the Plan may not be anticipated,  alienated,
sold,  transferred,
         assigned,  pledged,  executed  upon,  encumbered,  or
subjected to any
         charge or legal process;  no interest or right to receive
a benefit may
         be taken, either voluntarily or involuntarily,  for the
satisfaction of
         the debts of, or other  obligations or claims  against,
such person or
         entity,  including  without  limitation,  any  judgment
or  claim  for
         alimony,  support  or  separate  maintenance  pursuant
to  a  domestic
         relations  order  within the meaning of Section
206(d)(3) of ERISA and
         claims in bankruptcy proceedings.  Any such attempted
disposition shall
         be null and void.

9.03.    Claims Release.

         In case of accident  resulting  in injury to or death of
a  Participant
         which entitles the Participant or his or her surviving
lawful spouse to
         benefits under the Plan, the Participant or his or her
surviving lawful
         spouse may elect to accept such benefits or to prosecute
such claims at
         law as the Participant or the surviving  lawful spouse
may have against
         one or more Participating  Companies.  If an election is
made to accept
         the  benefits  under the Plan,  such  election  shall be
in writing and
         shall  release  such   Participating   Company  or  such
Participating
         Companies  from all claims and demands that the
Participant  or his or
         her  surviving  lawful  spouse may have  against  it, or
against  them,
         otherwise than under this Plan or under any other plan
maintained by a
         Participating  Company,  on account of such accident.
The right of the
         Participant to a disability allowance under Article 2 of
the Plan shall
         lapse if election to accept such benefits,  as above
provided,  is not
         made within sixty days after injury, or within such
greater time as the
         Company shall fix for the making of such election.

9.04.    Damage Claims or Suits.

         Should a claim  other  than  under  this Plan or under
any other  plan
         maintained  by a  Participating  Company be  presented
or suit brought
         against a  Participating  Company,  for damages on
account of injury or
         death of a  Participant,  nothing  shall be payable
under this Plan on
         account of such injury or death  except as  provided  in
Section  9.05,
         provided,  however,  that the Company may, in its
discretion  and upon
         such terms as it may prescribe  waive this  provision if
such claims be
         withdrawn or if such suit be discontinued.

9.05.    Judgment or Settlement.

         In case any judgment is recovered  against a
Participating  Company or
         any settlement is made of any claim or suit on account of
the injury or
         death of a Participant, and the total amount which would
otherwise have
         been payable under the Plan and under any other plan
maintained by the
         Participating  Company  is greater  than the amount  paid
on account of
         such judgment or settlement,  the lesser of (a) the
difference  between
         such two  amounts or (b) the amount  which  would
otherwise  have been
         payable  under this Plan,  may in the  discretion  of
the  Company,  be
         distributed to the beneficiaries who would have received
benefits under
         this Plan.

9.06.    Forfeiture of Benefits.

         All Benefits to which a Participant  and his or her
lawful spouse would
         be otherwise eligible hereunder may be forfeited,  at the
discretion of
         the Board or of the Committee,  if an individual  without
the Company's
         consent  establishes a relationship with a competitor of
the Company or
         engages in any activity in conflict with or adverse to
the interests of
         the Company under the standards of the AT&T
Non-Competition  Guideline
         and as determined by the Board or the Committee in its
sole discretion.

9.07.    Payment under Law.

         In the case of any benefit,  which the Committee  shall
determine to be
         of the same general  character as a payment provided by
the Plan, shall
         be payable to any participant, to his or her
beneficiaries,  his or her
         estate or his or her annuitant  under any law now in
force or hereafter
         enacted,  only the excess, if any, of the amount
prescribed in the Plan
         above the  amount of such  payment  prescribed  by law
shall be payable
         under the Plan;  provided,  however,  that no benefit
payable under the
         Plan shall be reduced by reason of any governmental
benefit or pension
         payable  on  account of  military  service or by reason
of any  benefit
         which the  recipient  would be  entitled  to  receive
under the Social
         Security Act or Railroad Retirement Act. In those cases
where,  because
         of  differences  in the  beneficiaries  or in the  time
or  methods  of
         payment  or  otherwise,  the  determination  of any such
excess is not
         ascertainable  by mere comparison but  adjustments  are
necessary,  the
         Committee  or  the   Administrator,   as  applicable,
shall,  in  its
         discretion, determine whether or not in fact any such
excess exists and
         make the  adjustments  necessary  to carry out in a fair
and  equitable
         manner the spirit of the provision for the payment of any
such excess.

9.08.    Governing Law.

         To the  extent  such laws are not  preempted  by the laws
of the United
         States of America,  the Plan shall be governed by the
laws of the State
         of New Jersey, except as to its principles of conflict of
laws.

9.09.    Severability.

         If any section,  clause,  phrase,  provision or portion
of this Plan or
         the application  thereof to any person or circumstance
shall be invalid
         or unenforceable  under any applicable law, such event
shall not affect
         or render invalid or unenforceable the remainder of this
Plan and shall
         not  affect the  application  of any  section,  clause,
provision,  or
         portion hereof to other persons or circumstances.

9.10.    Facility of Payment.

         If the  Administrator  shall find that any person to whom
any amount is
         or was payable  under the Plan is unable to care for his
or her affairs
         because of illness or accident,  then any payment, or any
part thereof,
         due to such person  (unless a prior claim  therefor  has
been made by a
         duly appointed  legal  representative),  may, if the
Administrator  so
         directs  AT&T, be paid to the same person or
institution  that benefit
         with  respect to such  person is paid or to be paid
under the  Pension
         Plan if applicable,  or the  Participant's  lawful
spouse,  a child, a
         relative, an institution  maintaining or having custody
of such person,
         or  any  other  person  deemed  by  the  Administrator
to be a  proper
         recipient on behalf of such person otherwise  entitled to

liability of AT&T,
         the Board,  the Committee,  the  Administrator,  and the
Participating
         Company therefor.  If any payment to which a Participant
or beneficiary
         is entitled  under this Plan is unclaimed  or otherwise
not subject to
         payment to the person or persons so entitled, such
amounts representing
         such payment or payments shall be forfeited after a
period of two years
         from the date the first such  payment was payable and
shall not escheat
         to any state or revert to any party;  provided,  however,
that any such
         payment or payments shall be restored if any person
otherwise  entitled
         to such payment or payments makes a valid claim.

                               Enrollment Package
Program Overview

The Directors  Individual Life Insurance Program (DILIP) is an arrangement where
the Company and you purchase a permanent life insurance  policy on your life and
share the premium payment. If you die while AT&T is still a party to the policy,
typically  before you reach age 70, the death benefit is also shared between the
Company and your designated beneficiary.  This type of arrangement this known in
the insurance industry as "Split Dollar." After attaining age 70 or if later, 10
years (in some cases it may be longer to avoid violation of the Internal Revenue
Service  Regulations  Section 7702 guidelines) from the date of issuance of this
policy,  the  Company  will  recoup  its  premium  payments  from the cash value
build-up  in the  policy  and  cease to have any  interest  in the  policy.  The
remaining  cash value will be sufficient  to give you a "paid-up"  death benefit
after  attaining  normal  retirement  age, i.e., all premiums will cease and the
death benefit of the policy will be secured for the designated  beneficiary with
no further cost to you.

At the time of  enrollment  your  death  benefit  will be  $100,000.  Your death
benefit will increase annually at 7%. The premium cost to you will also increase
to reflect your  increasing  age as well as the  increased  death  benefit.  The
Company  will  pay a  significant  portion  of the  premium  (see  the  attached
illustration). Over time, the Company portion of the premium will decrease.

Although  this  arrangement  is  primarily  designed to pay a benefit  upon your
death, there is also a cash value build-up occurring coincident with the premium
payments that continues after the premium payments cease.  Once sufficient funds
have  accumulated  and the  Company no longer  has an  interest  in the  policy,
because it has recouped its premiums,  you have the option to use some or all of
the remaining cash in lieu of some or all of the death benefit.

Eligibility

DILIP is for non-employee members of the AT&T Board of Directors.

Coverage

The death benefit will automatically increase 7% on January 1 of each year.

Insurability

If you enroll within 60 days of becoming a Board Member,  you are  guaranteed to
be insured.  If you choose to delay  enrollment,  proof of  insurability  may be
required at that time before a policy can be written or coverage  increased.  If
you are on disability  at the time of  eligibility,  enrollment  must be delayed
until you return to work.



<PAGE>


Premium Sharing/Benefit Sharing

DILIP  has its  origin in what the  insurance  industry  calls a "Split  Dollar"
program.  The term "Split Dollar" insurance comes from a concept of the Employer
and the Employee  sharing the premium payment on a life insurance  policy on the
employee.  At age 70 or if later,  10 years  (in some  cases it may be longer to
avoid  violation  of the  Internal  Revenue  Service  Regulations  Section  7702
guidelines)  from the date of issuance of the policy,  the  Company's  aggregate
premiums  are  returned  from a  "special"  cash  value  built  into the  policy
expressly  for this  purpose.  Should  you die before  the  Company's  aggregate
premiums are returned,  death benefit  payments are made to both the Company and
your beneficiary.  However, the benefit the Company receives does not reduce the
death benefit paid to your beneficiary.  After the Company's  aggregate premiums
are returned,  the Company no longer has an interest in the policy. At that time
you will have a "paid up" permanent life insurance policy with a cash value that
can be made available to you at your option.

* This example is for illustrative  purposes only and assumes a 7% annual growth
in death benefit  (assumed  base salary) and an 8% yield on  investment  for the
cash value. The yield on investment is not guaranteed.

# At normal retirement the death benefit becomes  constant,  premiums cease, the
Company's  aggregate  premiums  are returned and your cash value may continue to
grow.

Premium Period

DILIP is designed for premiums to be extended  over a period of time to ease the
impact on cash flow to both you and the  Company.  This period is normally  from
the time of your enrollment  until you reach age 70,  however,  premiums must be
paid  for a  minimum  of 10  years  (in some  cases  it may be  longer  to avoid
violation of the Internal Revenue Service  Regulations Section 7702 guidelines).
Therefore,  if you enroll in the program  after age 60, you and the Company will
continue premium contributions until the minimum is reached.



<PAGE>


Premium Amount

Included as an attachment is a personal  illustrations.  The illustration  shows
the Company's as well as your annual premium through the life of the policy.

Premium Waivers

There are no Premium Waivers associated with this policy.

Ownership

There are three options:

         Board Member as Owner
         All paperwork  should be signed by Senior  Manager as proposed  insured
and owner.

         Owner at Enrollment is not the Board Member
         Another option is for you not to take  ownership,  but
rather  another,
         i.e., individual, trust, etc., apply for ownership of the
policy. It is
         of  particular  importance  that if the owner of the
policy is not you,
         the  owner  must  sign as the  "Applicant/Owner"  and you
must sign the
         application as the "Proposed Insured".

         Transfer of Ownership
         The  owner  of this  policy  may  subsequently  transfer
ownership  to
         another, i.e., an individual, trust, etc. Please contact
Kathy Pruna at
         908 630-2827 for the necessary forms and/or information.

Since ownership has long term and/or  irrevocable  implications,  we urge you to
consult with an attorney and/or tax advisor before making this decision.

Cash Value

This  program is designed to provide you with a pre- and  post-retirement  death
benefit.  However,  in  addition  to the death  benefit,  there is a cash  value
build-up.  That is, part of each  premium is placed in an  "investment  fund" to
earn income.  Investment  earnings beyond the amounts  necessary to increase the
death benefit, build on a tax advantaged basis in the policy.



<PAGE>


Cash Availability

         Cash Build-up

         Your share of the cash build-up will not begin until
several years into
         the policy but will build  quickly after that. As with
any cash amount,
         the longer it is left intact the greater the amount will
be.

         Loans

         The cash value attributed to you may be withdrawn in the
form of a loan
         after the Company no longer has an  interest  in the
policy.  There are
         certain  restrictions and tax  implications  associated
with a loan. We
         suggest that you speak with your financial counselor/tax
advisor before
         taking such a step.

         Income Stream or Lump Sum

         It is possible, after retirement,  to convert all or any
portion of the
         policy  from a death  benefit to either an income
"stream"  (i.e.,  an
         annuity) or a lump sum cash payout.  The extent to which
you convert to
         income or cash will cancel or reduce the valuable death
benefit.  Once
         you convert,  it is not  possible to  re-establish  the
original  death
         benefit.

Early Retirement

If you before age 70, the death benefit will continue to increase  until age 70.
Both you and the Company will continue to pay premiums until you reach age 70 or
if later,  10 years (in some  cases it may be longer to avoid  violation  of the
Internal Revenue Service  Regulations  Section 7702 guidelines) from the date of
issuance of the policy.  At that time the premiums  will cease and the Company's
aggregate premiums will be returned to the Company. If you leave the Company and
engage in competitive  activity as determined by AT&T,  the Company's  aggregate
premiums will be immediately  returned to the Company.  You can, at your option,
either  maintain the policy by continuing to pay the total premium,  i.e.,  both
your amount and the amount  previously  paid by the Company,  use the  remaining
cash value (if any) to buy paid up life  insurance,  or withdraw  any  remaining
cash value and cancel the policy.

Contractual Agreement

One of the  unique  aspects  of this  insurance  policy  is the  existence  of a
contract  between you and AT&T. This agreement has no relationship to employment
or any other benefit but rather defines the responsibilities of both the Company
and you in the  operation of the policy.  You will own the policy and  determine
who  beneficiary.  The  Company  will  hold the  policy  and have a  "Collateral
Assignment"  from the owner (you or another you name) entitling AT&T, as long as
it has a collateral  interest in the policy,  to an amount equal to its premiums
paid.  This  document is a legal  agreement  and as such  includes a significant
amount of detail and  warrants  your careful  review  before  signing.  Although
somewhat unique to life insurance, a collateral assignment is similar in context
to an automobile loan where the car becomes  "collateral"  for the money lent to
buy it. In this case,  a portion  of the value and  benefit of the policy is the
collateral the Company receives for  contributing  premium payments to "buy" the
life insurance  policy.  The agreement is satisfied when the premium paid by the
Company is returned. Some of the major sections of the agreement are:

                  - Description  of the policy - How the premiums
are paid - How
                  the proceeds are paid - How the agreement
terminates - Claims
                  procedure - Description of the assignment

The Agreement is included with this package.

Taxes

Split Dollar life insurance policies have been in existence for decades. The IRS
has issued several rulings over this period which treat these policies favorably
from a tax perspective.  However, the Company does not assure any particular tax
treatment and  recommends  that you review your own situation with your personal
attorney and/or tax advisor.

Enrollment

Included  with this  package are the  documents  required  for  enrolling in the
Directors   Individual  Life  Insurance  Program.  The  Application  Form  while
appearing  lengthy  requires,  for our  purposes,  just a few  basic  pieces  of
information,  as does the Beneficiary  Designation form. Both of these documents
include  instructions  on how to complete.  The Collateral  Assignment  requires
signatures only.

                           ADMINISTRATION OF THE PLAN

                    AT&T EXCESS BENEFIT AND COMPENSATION PLAN

                 AMENDED and RESTATED effective October 1, 1996

                                     Article

                            1. Background and Purpose

         The AT&T  Excess  Benefit  Plan was  established  to  provide  eligible
management and occupational employees of AT&T Corp. (formerly American Telephone
and Telegraph  Company) ("AT&T") and its subsidiaries that became  Participating
Companies  with certain  benefits  which would have been payable  under the AT&T
Management  Pension Plan or the AT&T  Pension  Plan,  respectively,  but for the
limitations placed on benefits payable under the AT&T Management Pension Plan or
the AT&T Pension Plan by section 415 of the  Internal  Revenue Code of 1986,  as
amended (and its  predecessor,  the Internal  Revenue Code of 1954,  as amended)
("Code").  Effective  January 1, 1989,  AT&T  established an additional  plan to
provide  eligible  management  employees with certain  benefits which would have
been payable  under the AT&T  Management  Pension  Plan but for the  limitations
placed on eligible compensation by Code ss. 401(a)(17). The aforementioned plans
are intended to encompass  those plans  identified  in AT&T's  December 28, 1992
filing with the Pension and Welfare Benefits Administration ("PWBA") in response
to the  PWBA's  September  21,  1992  Notice  (Extension  of  Grace  Period  for
Assessment of Civil  Penalties for Failure to File Timely Annual Return Reports;
Top Hat Plans and  Pre-Grace  Period Late  Filers).  These plans are amended and
restated,  effective  January 1, 1994,  and shall  hereinafter  be  referred  to
collectively as the "AT&T Excess Benefit and Compensation Plan" or "Plan."

         The Plan is intended to constitute an unfunded "excess benefit plan" as
defined in section 3(36) of the Employee Retirement Income Security Act of 1974,
as amended  ("ERISA"),  to the extent it  provides  benefits  that would be paid
under the AT&T  Management  Pension  Plan or the AT&T  Pension  Plan but for the
limitations  imposed  by  Code  ss.  415,  and an  "unfunded  plan  of  deferred
compensation for a select group of management or highly  compensated  employees"
for purposes of Title I of ERISA, to the extent it provides other benefits.

         Except as expressly  provided  below,  this  amended and restated  plan
document applies only to employees who terminate  employment on or after October
1, 1996. For former employees who terminated employment before
October 1, 1996,
the  provisions of the AT&T Excess  Benefit and  Compensation  Plan in effect at
termination of the former employee's employment governs.

         Effective  October 1, 1996, Lucent  Technologies  Inc.  established the
Lucent  Technologies Inc. Excess Benefit and Compensation Plan as a successor to
the AT&T Excess  Benefit and  Compensation  Plan,  in effect as of September 30,
1996,  with  respect to  Transferred  Individuals  (as  defined  in Article  2).
Accordingly,  the AT&T Excess Benefit and Compensation  Plan relinquished to the
Lucent Technologies Inc. Excess Benefit and Compensation Plan all liabilities as
of  September  30, 1996  relating  to  Transferred  Individuals,  and the Lucent
Technologies  Inc.  Excess Benefit and  Compensation  Plan assumed and is solely
responsible  for all such  liabilities.  Except to the extent required by law or
Article 5 of this Plan,  the Plan shall not recognize  service and  compensation
before October 1, 1996 with respect to Transferred Individuals.  Effective as of
the date an individual becomes a "Transition  Individual" (as defined in Section
1.38(a) or (d) of the Management Interchange Agreement or Section 1.30(a) or (d)
of the Occupational  Interchange  Agreement),  the Plan shall also assume and be
solely responsible for all liabilities relating to such Transition Individuals.

benefit  actually
         payable  to  such  Participant  or  Surviving  Spouse
under  the  AT&T
         Management Pension Plan or the AT&T Pension Plan.

         The amount of the Excess Retirement  Benefit payable as a result of the
application of the Benefit  Limitation under the AT&T Management Pension Plan or
the AT&T Pension Plan shall be determined or  redetermined,  based upon the AT&T
Management  Pension Plan or the AT&T Pension Plan  formula,  as  applicable,  in

Benefit prior to age 55 and/or for the cost of the survivor annuity,  if any, in

 4.3.     Commencement and Form of Benefits Payable to Participant
or  Surviving
Spouse

         The Excess  Retirement  Benefit  provided  under  this Plan  payable to

time, (b) shall be paid for as long as (subject to Section 4.2) and (c) shall be
paid  in the  same  benefit  form as the  Participant's  or  Surviving  Spouse's
benefits  are paid under the AT&T  Management  Pension  Plan or the AT&T Pension
Plan; whichever is applicable,  provided, however, that the Committee shall have
the  right to  approve  the  Participant's  election  of the form of the  Excess
Retirement Benefit payable to the Participant.

 4.4.     No Surviving Spouse

         If a  Participant  dies  before the date as of which his or her benefit
commences under the AT&T  Management  Pension Plan or the AT&T Pension Plan, and
he or she does not  have a  Surviving  Spouse  on his or her date of  death,  no
Excess Retirement  Benefit shall be paid after the death of the Participant with
respect to the Participant.

 4.5.     Future Benefit Adjustments

         (a)......If  a  Participant  has  commenced   receiving  a  service  or
disability  pension under the AT&T  Management  Pension Plan or the AT&T Pension
Plan in the  form of a joint  and 50  percent  survivor  annuity  and his or her
designated  annuitant  subsequently  predeceases  him or her, the  Participant's
Excess Retirement Benefit under this Plan shall be calculated in accordance with
Section 4.02 and thereafter paid, prospectively,  by restoring the original cost
of the joint and 50 percent  survivor  annuity  form of  benefit  under the AT&T
Management Pension Plan or the AT&T Pension Plan, whichever is applicable.  Such
adjustment  shall be effective as of the first day of the first month  following
the death of the Participant's surviving annuitant.

         (b)......In  the event that,  following  commencement  of benefits to a
Participant  under  the  Plan,  the AT&T  Management  Pension  Plan  benefit  is
subsequently adjusted to include any payments considered  Compensation under the
AT&T  Management  Pension Plan paid after  commencement  of the AT&T  Management
Pension Plan benefit,  the Excess  Retirement  Benefit to the Participant  under
this Plan shall be recalculated as soon as practicable after the AT&T Management
Pension Plan benefit is adjusted and shall be paid retroactively to the date the
AT&T Management Pension Plan benefit  commences,  if the AT&T Management Pension
Plan benefit is adjusted retroactively to such date.

         (c)......In  the event that,  following  commencement  of benefits to a
Participant or Surviving Spouse under the Plan, the AT&T Management Pension Plan
or AT&T  Pension  Plan  benefit  is  subsequently  increased  as a  result  of a
successful  claim for benefits  under the AT&T  Management  Pension Plan or AT&T
Pension Plan,  the Excess  Retirement  Benefit to the  Participant  or Surviving
Spouse under this Plan shall be  recalculated  as soon as practicable  after the
AT&T Management Pension Plan or the AT&T Pension Plan benefit is adjusted.

 4.6.     Determination of Benefits

         Excess  Retirement  Benefit  payments and Excess Death Benefit payments
under this Plan shall be calculated in  accordance  with the rules,  procedures,
and  assumptions  utilized  under the AT&T  Management  Pension Plan or the AT&T
Pension  Plan,  whichever  is  applicable.  Thus,  whenever it is  necessary  to
determine whether one benefit is less than, equal to, or larger than another, or
to determine the equivalent actuarial value of any benefit,  whether or not such
form of benefit is provided under this Plan, such  determination  shall be made,
at the Administrator's  discretion, by AT&T's enrolled actuary, using mortality,
interest  and  other  assumptions  normally  used  at the  time  in  determining
actuarial  equivalence  under the AT&T  Management  Pension Plan or AT&T Pension
Plan, whichever is applicable.

 4.7.     Suspension and Recommencement of Benefit Payments

         A Participant's  employment or reemployment subsequent to retirement or
termination of employment with entitlement to an Excess Retirement Benefit under
this Plan  shall  result in the  permanent  suspension  of payment of the Excess
Retirement  Benefit  to the  Participant  for the period of such  employment  or
reemployment  to the  extent  and in a  manner  consistent  with the  terms  and
conditions  applicable  to the  suspension  of benefit  payments  under the AT&T
Management  Pension Plan or the AT&T Pension Plan,  whichever is  applicable.  A
Participant's Excess Retirement Benefit shall recommence simultaneously with the
recommencement of his or her benefits under the AT&T Management  Pension Plan or
the AT&T Pension Plan. The amount of the Participant's Excess Retirement Benefit
upon  recommencement  shall be adjusted to reflect  adjustments,  if any, in the
amount of the  Participant's  pension benefit under the AT&T Management  Pension
Plan or the AT&T  Pension  Plan  resulting  from  the  period  of  reemployment,
pursuant to Section 4.2.  Following  recommencement  of payment under this Plan,
the  Participant  (or  Surviving  Spouse)  shall not be  eligible to receive any
Excess  Retirement  Benefit  payments that would otherwise have been payable but
for the suspension.

 4.8.     Mandatory Portability Agreement

         A Participant (a) who is employed by an "Interchange  Company", as that
term is defined under the Mandatory Portability Agreement ("MPA"), subsequent to
retirement or  termination  of employment  from AT&T,  its  subsidiaries  or any
Affiliated  Company,  (b) who is covered  under the terms and  conditions of the
MPA,  and (c) for whom  assets and  liabilities  are  transferred  from the AT&T
Management Pension Plan or the AT&T Pension Plan, shall forfeit his rights to an
Excess  Retirement  Benefit  under  this  Plan,  including  the  rights  of  the
Participant's  spouse to an Excess Retirement  Benefit as a Surviving Spouse and
the rights of Beneficiary to an Excess Death Benefit.

 4.9.     Excess Death Benefit

         (a)......If the actual  Accident Death Benefit,  Sickness Death Benefit
or Pensioner Death Benefit ("Death  Benefit")  payable to any person as a result
of the death of a  Participant  under the terms of the AT&T  Management  Pension
Plan is reduced or limited by reason of the Compensation  Limitation,  an Excess
Death Benefit  shall be paid as provided in this Section 4.9 to the  beneficiary
otherwise  entitled to receive the Death Benefit under the terms and  conditions
of the AT&T Management Pension Plan.

         (b)......The  amount, if any, of the Excess Death Benefit payable shall
be equal to the difference between (i) and (ii) where:

                  (i) is the amount of the Death Benefit which
would be provided
         to the  beneficiary  under the AT&T  Management  Pension
Plan  without
         regard to the Compensation Limitation under the AT&T
Management Pension
         Plan in effect as of the date of death; and

                  (ii) is the amount of the Death  Benefit  actually  payable to
such beneficiary under the AT&T Management Pension Plan.

         (c)......The  Excess Death Benefit  provided  under this Plan (i) shall
commence at the same time, (ii) shall be paid for as long as, and (iii) shall be
paid in the same  benefit form as the  Committee or its delegate has  determined
with respect to the Death  Benefit  payable  under the AT&T  Management  Pension
Plan.

Company

         (a)......Subject  to  Sections  4.8 and 9.1,  in the event AT&T  sells,
spins off, or otherwise  disposes of a Subsidiary or an Affiliated  Corporation,
or  disposes of all or  substantially  all of the assets of a  Subsidiary  or an
Affiliated  Corporation such that one or more Participants  terminate employment
for the purpose of  accepting  employment  with the  purchaser  of such stock or
assets,  any person  employed by such  Subsidiary or Affiliated  Corporation who
ceases to be an employee as a result of the sale, spin-off, or disposition shall
be deemed to have terminated his or her employment with a Participating  Company
and be eligible for an Excess Retirement  Benefit commencing at the same time as
his or her benefit,  if any, commences under the AT&T Management Pension Plan or
the AT&T Pension Plan.  Further,  if the Participant  dies after  termination of

entitled  to an Excess  Retirement  Benefit,  if eligible as provided in Section
4.1,  and/or his or her  Beneficiary may be entitled to an Excess Death Benefit,

Retirement  Benefit  and/or the Excess Death  Benefit to which the  Participant,
Surviving Spouse and/or  Beneficiary would have been entitled under the Plan but

Participant  or his or her  Surviving  Spouse  to an Excess  Retirement  Benefit
and/or  any  Beneficiary  to an Excess  Death  Benefit  under  this  Plan  shall
terminate.  Any subsequent  entitlement of the former  Participant or his or her
Surviving  Spouse or  Beneficiary  to the Excess  Retirement  Benefit and/or the
Excess Death Benefit  shall be the sole  responsibility  of the assuming  party.
Upon the  assumption of the  liability  for the payment of an Excess  Retirement
Benefit and Excess Death Benefit by Lucent Technologies Inc. pursuant to Section

                              6. Source of Payment

 6.1.     Source of Payments

         Benefits arising under this Plan and all costs,  charges,  and expenses
relating thereto will be payable from the Company's general assets.  The Company
may,  however,  establish a trust to pay such  benefits  and  related  expenses,
provided such trust does not cause the Plan to be "funded" within the meaning of
ERISA.  To the  extent  trust  assets  are  available,  they  may be used to pay
benefits arising under this Plan and all costs,  charges,  and expenses relating
thereto.  To  the  extent  that  the  funds  held  in the  trust,  if  any,  are
insufficient  to pay such  benefits,  costs,  charges and expenses,  the Company
shall pay such benefits,  costs,  charges, and expenses from its general assets.
In addition,  the Company may, in its sole  discretion,  purchase and distribute
one or more commercial annuity  contracts,  or cause the trustee of the trust to
purchase  and  distribute  one or more  commercial  annuity  contracts,  to make
benefit payments required under this Plan, to any Senior Manager,  as defined in
the AT&T  Non-Qualified  Pension  Plan,  or the  Surviving  Spouse of any Senior
Manager,  provided,  however,  that the  purchase and  distribution  of any such
annuity  contracts  shall be no sooner  than the  expiration  of any  forfeiture
provisions  applicable  to the  Senior  Manager  under the AT&T  Non-Competition
Guidelines.  Such annuity  contracts may be purchased from a commercial  insurer
acceptable to the  Executive  Vice  President - Human  Resources.  Further,  the
Executive  Vice  President  -  Human  Resources,  may  determine,  in  his  sole
discretion,  to pay additional  sums to any Senior  Manager,  from the Company's
general  assets or from the trust,  if any, to reimburse the Senior  Manager for
additional  federal and state income taxes estimated to be incurred by reason of
the  distribution  of any such annuity  contracts.  The Executive Vice President
Human Resources shall establish a methodology or  methodologies  for determining
the amount of such additional  sums. The methodology or  methodologies  selected
shall be those that the Executive Vice President - Human  Resources  determines,
in his sole discretion,  to be the most effective and administratively  feasible
for  the  purpose  of  producing  after  tax  periodic   benefit  payments  that
approximate  the  after tax  periodic  benefit  payments  that  would  have been
received by Senior  Managers in the absence of the  distribution  of the annuity
contract.

 6.2.     Unfunded Status

         The Plan at all times shall be entirely  unfunded  for  purposes of the
Code and  ERISA  and no  provision  shall at any time be made  with  respect  to
segregating  any assets of a  Participating  Company for payment of any benefits
hereunder.  Funds that may be invested  through a trust described in Section 6.1
shall  continue  for  all  purposes  to be  part of the  general  assets  of the
Participating  Company  which  invested the funds.  The Plan  constitutes a mere
promise  by AT&T  and the  Participating  Companies  to make  Excess  Retirement
Benefit payments and Excess Death Benefit  payments,  if any, in the future.  No
Participant, Surviving Spouse or any other person shall have any interest in any
particular assets of a Participating Company by reason of the right to receive a
benefit under the Plan and to the extent the  Participant,  Surviving  Spouse or
any other  person  acquires a right to receive  benefits  under this Plan,  such
right shall be no greater than the right of any unsecured  general creditor of a
Participating Company.

 6.3.     Fiduciary Relationship

         Nothing  contained  in the Plan,  and no action  taken  pursuant to the
provisions  of the Plan,  shall  create or be  construed  to create a trust or a
fiduciary  relationship between or among AT&T, any other Participating  Company,
the Board, the  Administrator,  the Committee,  any  Participant,  any Surviving
Spouse, or any other person, except as provided in Section 7.4.

                              9. General Provisions

 9.1.     Binding Effect

         The  Plan  shall be  binding  upon and  inure  to the  benefit  of each
Participating  Company and its successors and assigns,  and to each Participant,
his or her successors,  designees,  Beneficiaries,  designated  annuitants,  and
estate.  The Plan  shall  also be  binding  upon any  successor  corporation  or
organization succeeding to substantially all of the assets and business of AT&T.
Nothing in the Plan shall  preclude AT&T from merging or  consolidating  into or
with,  or  transferring  all or  substantially  all of its  assets  to,  another
corporation  which assumes the Plan and all obligations of AT&T hereunder.  AT&T
agrees  that it will make  appropriate  provision  for the  preservation  of the
rights of Participants,  Surviving Spouses and  Beneficiaries  under the Plan in
any  agreement or plan or  reorganization  into which it may enter to effect any
merger,  consolidation,  reorganization,  or  transfer  of  assets.  Upon such a
merger,  consolidation,   reorganization,   or  transfer  of  assets,  the  term
"Participating Company" shall refer to such other corporation and the Plan shall
continue in full force and effect.

 9.2.     No Guarantee of Employment

         Neither the Plan nor any action taken  hereunder  shall be construed as
(i) a contract of employment or deemed to give any  Participant  the right to be
retained in the employment of a Participating Company, the right to any level of
compensation,  or the  right  to  future  participation  in the  Plan;  or  (ii)
affecting  the right of a  Participating  Company to  discharge  or dismiss  any
Participant at any time.

 9.3.     Tax Withholding

         AT&T or a  Participating  Company,  as  applicable,  shall withhold all
federal, state, local, or other taxes required by law to be withheld from Excess
Retirement  Benefit  payments under the Plan.  AT&T shall also withhold all FICA
taxes  required  by law  to be  withheld  on an  Executive's  Excess  Retirement
Benefits under the Plan.

 9.4.     Assignment of Benefits

         No Excess Retirement Benefit or Excess Death Benefit under this Plan or
any right or interest in such Excess Retirement  Benefit or Excess Death Benefit
shall be assignable or subject in any manner to anticipation,  alienation, sale,
transfer, claims of creditors,  garnishment,  pledge,  execution,  attachment or
encumbrance of any kind, including, but not limited to, pursuant to any domestic
relations order (within the meaning of ERISA ss.
206(d)(3)  and Code ss.
414(p)(1)(B)) or judgment or claims for alimony,  support, separate maintenance,
and claims in bankruptcy  proceedings,  and any such attempted disposition shall
be null and void.

 9.5.     Facility of Payment

         If the  Administrator  shall find that any person to whom any amount is
or was payable  under the Plan is unable to care for his or her affairs  because
of illness or  accident,  then any  payment,  or any part  thereof,  due to such
person (unless a prior claim  therefor has been made by a duly  appointed  legal
representative),  may, if the Administrator so directs AT&T, be paid to the same
person or institution that the benefit with respect to such person is paid or to
be paid  under  the  AT&T  Management  Pension  Plan or AT&T  Pension  Plan,  if
applicable,  or the  Participant's  lawful  spouse,  a  child,  a  relative,  an
institution  maintaining or having  custody of such person,  or any other person
deemed by the  Administrator  to be a proper  recipient on behalf of such person
otherwise  entitled to payment.  Any such payment shall be in complete discharge
of the liability of AT&T, the Board, the Committee,  the Administrator,  and the
Participating Company therefor. If any payment to which a Participant, Surviving
Spouse or  Beneficiary is entitled under this Plan is unclaimed or otherwise not
subject  to  payment  to  the  person  or  persons  so  entitled,  such  amounts
representing  such payment or payments shall be forfeited  after a period of two
years from the date the first such  payment was payable and shall not escheat to
any state or revert to any party;  provided,  however,  that any such payment or
payments shall be restored if any person  otherwise  entitled to such payment or
payments makes a valid claim.

 9.6.     Severability

         If any section,  clause, phrase,  provision, or portion of this Plan or
the  application  thereof  to any  person or  circumstance  shall be  invalid or
unenforceable  under any  applicable  law, such event shall not affect or render
invalid or  unenforceable  the  remainder  of this Plan and shall not affect the
application  of any  section,  clause,  provision,  or  portion  hereof to other
persons or circumstances.

 9.7.     Plan Year

         For purposes of  administering  the Plan, each plan year shall begin on
January 1 and end on December 31.

 9.8.     Headings

         The captions  preceding  the  sections  and  articles  hereof have been
inserted solely as a matter of convenience and shall not in any manner define or
limit the scope or intent of any provisions of the Plan.

 9.9.     Governing Law

         The Plan  shall be  governed  by the  laws of the  State of New  Jersey
(other than its conflict of laws provisions) from time to time in effect, except

America.

 9.10.    Entire Plan

         This written Plan document is the final and exclusive  statement of the
terms of this Plan, and any claim of right or  entitlement  under the Plan shall
be determined  in  accordance  with its  provisions  pursuant to the  procedures
described  in  Article  7.  Unless  otherwise  authorized  by the  Board  or its

by  which  such
                        Officer's  age at the time benefits are
first paid under

pursuant  to the
                        Pension Plan or a retired Officer.


         (b)      Alternate  Formula.  The annual  benefit  under
the  Alternate
                  Formula  shall be the  excess of B over A,

of one percent
                  (0.8%) of the Participant's Covered Compensation
Base, and the
                  Participant's  Term of Employment.  The service
benefit under
                  this  Alternate  Formula will be reduced in case
of retirement
                  before age 60 by applying  the  appropriate
reduction  factor
                  from the Table of such  factors  shown in
Appendix  C to such
                  benefit.

                  Alternate  Minimum Formula in this Section
4.02(c) shall be an

         The annual benefit  determined under this Article 4 shall
be divided by
         twelve  (12) and shall be payable  monthly or at such

                                SOURCE OF PAYMENT

6.01.    Source of Payments.

         AT&T may  establish a trust to hold  assets to be used to
make  benefit
         payments  under the terms of this  Plan,  provided  such
trust does not
         cause the Plan to be  "funded"  within  the  meaning  of
ERISA.  Funds
         invested  hereunder  shall, for purposes of this Plan, be
considered to
         be  part of the  general  assets  of the  Participating
Company  which
         invested the funds,  and no  Participant,  beneficiary or
lawful spouse
         shall have any  interest  or right in such funds.  To the
extent  trust
         assets are  available,  they may be used to pay benefits
arising under
         this Plan and all costs,  charges and expenses relating
thereto. To the
         extent  that the funds held in the trust are
insufficient  to pay such
         benefits,   costs,  charges  and  expenses,  AT&T  or
the  responsible
         Participating  Company  shall pay such  benefits,
costs,  charges  and
         expenses from its general  assets.  In addition,  AT&T
may, in its sole
         discretion,  direct  that  payments  required  under
this  Plan to any
         Participant or surviving lawful spouse be made through
the purchase and
         distribution of one or more nontransferable  annuity
contracts or cause
         the  trustee  of the trust to  purchase  and  distribute
such  annuity
         contracts.  Any such purchase and  distribution of an
annuity  contract
         shall be a full and complete  discharge  of the Plan's,
AT&T's and the
         Participating  Companies'  liability for payments assumed
by the issuer
         of the annuity  contract.  Further,  the Senior Vice
President,  Human
         Resources,  may determine,  in his sole  discretion,  to
pay additional
         sums to any Senior Manager,  from the Company's  general
assets or from
         the trust,  if any, to  reimburse  the Senior  Manager
for  additional
         federal and state  income  taxes  estimated to be
incurred by reason of
         the  distribution  of any  such  annuity  contracts.
The  Senior  Vice
         President,   Human   Resources   shall   establish  a
methodology   or
         methodologies  for determining the amount of such
additional  sums. The
         methodology  or  methodologies  selected shall be those
that the Senior
         Vice President,  Human Resources determines, in his sole
discretion, to
         be the most effective and administratively  feasible for
the purpose of
         producing  after tax periodic  benefit  payments that
approximate  the
         after tax periodic  benefit  payments  that would have
been received by
         [Senior  Managers]  in the absence of the  distribution
of the annuity
         contract.

6.02.    Unfunded Status.

         The Plan at all times shall be entirely  unfunded  for
purposes of the
         Internal  Revenue  Code of 1986 and ERISA,  and,  except
as provided in
         Section  6.01,  no provision  shall at any time be made
with respect to
         segregating  any assets of a  Participating  Company for
payment of any
         benefits  hereunder.  The  Plan  constitutes  a  mere
promise  by  the
         Participating  Company to make  payments,  if any,  in
the  future.  No
         Participant, surviving lawful spouse or any other person
shall have any
         interest in any particular assets of a Participating
Company by reason
         of the right to receive a benefit  under the Plan and to
the extent the
         Participant,  surviving  lawful  spouse or any other
person  acquires a
         right to  receive  benefits  under this  Plan,  such
right  shall be no
         greater  than  the  right  of  any  unsecured  general
creditor  of  a
         Participating Company.

                           ADMINISTRATION OF THE PLAN




7.01.    Administration and Authorities.

         The Plan shall be  administered  by the  Company and it
shall have full
         discretionary  authority  to  manage  and  control  the
operation  and
         administration of the Plan, including the power to
interpret provisions
         of  the  Plan,  make  determinations  of  fact,
promulgate  rules  and
         regulations, determine benefit eligibility of individual
and classes of
         Participants  (including,  without  limitation,
determinations  of  a
         Participant's applicable Term of Employment,  Position
Rate and rate of
         pay),  delegate its powers and duties  hereunder to the
Committee,  the
         Administrator  or others  and take such  other  action as
it shall find
         necessary and  appropriate to implement the provisions of
the Plan. The
         Committee  and the  Administrator  may retain
attorneys,  consultants,
         accountants or other persons (who may be employees of the
Company or an
         Affiliated  Corporation)  to  render  advice  and
assistance  and  may
         delegate any of the  authorities  conferred on it to such
persons as it
         shall determine to be appropriate to effect the discharge
of its duties
         hereunder.  The Company,  the Affiliated  Corporations
and any of their
         Officers  and  E-band  Employees  shall be  entitled  to
rely  upon the
         advice,  opinions, and determinations of any such
persons. Any exercise
         of the authorities  set forth in this Section,  whether
by the Company,
         the Committee or its Delegate, or the Administrator,
shall be final and
         binding upon the Company, its Affiliated Corporations,
their officers,
         directors and affected Participants and beneficiaries.

7.02.    Committee.

         The Company has delegated to the Committee  authority to
make the final
         determination  to grant or deny claims for benefits under
the Plan with
         respect  to   Participants,   surviving   lawful
spouses,   and  other
         beneficiaries and to authorize  disbursements according
to the terms of
         the Plan.

7.03.    Indemnification.

         No member of the Board,  the  Committee or the
Administrator  shall be
         personally  liable  by  reason  of any  contract  or
other  instrument
         executed  by  such  individual  or on his or her  behalf
in his or her
         capacity as a member of the Board,  Committee or the
Administrator nor
         for any  mistake  of  judgment  made  in good  faith,
and  AT&T  shall
         indemnify and hold  harmless  each member of the Board,
each member of
         the Committee,  the Administrator and each other
employee,  officer, or
         director of AT&T or any Participating Company to whom any
duty or power
         relating to the  administration  or  interpretation  of
the Plan may be
         allocated  or  delegated,   against  any  cost  or
expense  (including
         attorneys' fees) or liability  (including any sum paid in
settlement of
         a claim)  arising out of any act or omission to act in
connection  with
         the Plan unless arising out of such person's own fraud or
bad faith.

7.04.    Benefit Claims and Appeals


         (a)      Benefit Claims. All claims for benefit payments
under the Plan
                  shall be  submitted in writing by  Participants
to the person
                  designated  by  the  Company  to  make
determinations  as  to
                  eligibility  for benefits under the Plan and
such person shall
                  notify the Participant in writing within 90 days
after receipt
                  as to  whether  the claim has been  granted  or
denied.  This
                  period  may be  extended  for up to an
additional  90 days in
                  unusual cases provided that written notice of
the extension is
                  furnished to the  claimant  prior to the
commencement  of the
                  extension. In the event the claim is denied,
such notice shall
                  (i) set forth the specific reason or reasons for
denial,  (ii)
                  make reference to the pertinent  Plan
provisions on which the
                  denial is based,  (iii)  describe any
additional  material or
                  information  necessary before the Participant's
request may be
                  acted upon  favorably,  and (iv)  explain  the
procedure  for
                  appealing the adverse determination.


         (b)      Benefit  Appeals.  A  Participant  whose  claim
for  benefits
                  has  been  denied  may,  within  60 days  of
receipt  of  any
                  adverse  benefit  determination,  appeal  such
denial  to the
                  Committee.  All   appeals  shall be  in  the
form of a written
                  statement  and  shall (i) set  forth  all  of
the  reasons in
                  support of favorable action on the appeal, (ii)
identify those
                  provisions of the Plan upon which the claimant
is relying, and
                  (iii) include copies of any other documents or
materials which
                  may   support  favorable  consideration   of
the  claim. The
                  Committee shall  decide  the issues  presented
within 60 days
                  after receipt of such request, but this period
may be extended
                  for up to an additional 60 days in unusual cases
provided that
                  written  notice of  the extension is furnished
to the claimant
                  prior to the  commencement  of the  extension.
The decision of
                  the Committee shall be set forth in writing,
include specific
                  reasons for  the decision,  refer to pertinent
Plan provisions
                  on which the decision is based, and shall be
final and bindin
                        on all persons affected thereby.

                       Adoption, Amendment and Termination




8.01.    Adoption of Plan.

         Any Affiliated  Corporation that  participates in the
Pension Plan may,
         with the consent of the  Committee,  elect to
participate in the Plan.
         Such Affiliated  Corporation shall become a Participating
Company as of
         the date  specified by the  Committee in its  resolution
approving the
         participation of the Affiliated Corporation in the Plan.

8.02.    Amendment and Termination.

         AT&T is the Sponsor of the Plan and the Board or its
Delegate, may from
         time to time  amend,  modify  or  change  the Plan as set
forth in this
         document, and the Board or its Delegate (acting pursuant
to the Board's
         delegations  of authority then in effect) may terminate
the Plan at any
         time. Plan amendments may include,  but are not limited
to, elimination
         or reduction in the level or type of benefits  provided
to any class or
         classes of Participant (and surviving lawful spouses).
Any and all Plan
         amendments  may  be  made  without  the  consent  of
any  Participant,
         surviving lawful spouse or beneficiary.  Notwithstanding
the foregoing,
         no such amendment, suspension or termination shall
retroactively impair
         or  otherwise  adversely  affect  the  rights  of  any
Participant  or
         surviving  lawful spouse to benefits  under the Plan to
which they have
         previously become entitled as a result of a
Participant's  satisfaction
         of the  vesting  schedule  of this Plan  which is the
same as and never
         will be greater than the vesting schedule under the
Pension Plan.

8.03.    Sale, Spin-Off, or Other Disposition of Participating
Company.


         (a)      Subject to Section 9.01 of this Plan, in the
event AT&T sells,
                  spins off, or otherwise disposes of an
Affiliated Corporation,
                  or  disposes of all or  substantially  all of
the assets of an
                  Affiliated  Corporation  such  that  one or
more  Participants
                  terminate  employment for the purposes of
accepting employment
                  with  the  purchaser  of such  stock  or
assets,  any  person
                  employed by such  Affiliated  Corporation  who
ceases to be an
                  employee  of the  Company or an  Affiliated
Corporation  as a
                  result of the sale,  spin-off,  or disposition
shall be deemed
                  to have  terminated his or her employment with a
Participating
                  Company for all relevant purposes under this Plan.


         (b)      Notwithstanding the foregoing provisions of this
Section 8.03,
                  and  subject  to  Section  9.01 of  this  Plan,
if the  sale,
                  spin-off,  or other  disposition  of the stock
or assets of an
                  Affiliated Corporation is to a Successor Plan
Sponsor with the
                  effect  that  a   Participant   is  or  becomes
a  Transition
                  Participant, the Successor Plan Sponsor shall be
solely liable
                  for the payment of the pension and death
benefits described in
                  this Plan, and the  entitlement of the
Transition  Participant
                  or  his or her  surviving  lawful  spouse  or
beneficiary  to
                  benefits  under  this  Plan  shall  terminate.
A  Transition
                  Participant  shall not be considered to have
terminated his or
                  her employment  with AT&T or a  Participating
Company for any
                  purpose under this Plan.

                               GENERAL PROVISIONS




9.01.    Binding Effect.

         The  Plan  shall be  binding  upon and  inure  to the
benefit  of each
         Participating   Company  and  its  successors  and
assigns,  and  each
         Participant,  employee,  his or  her  successors,
assigns,  designees,
         spouse,  and estate.  The Plan shall also be binding upon
any successor
         corporation  or  organization  succeeding to
substantially  all of the
         assets and  business of AT&T,  but  nothing in the Plan
shall  preclude
         AT&T from merging or consolidating into or with, or
transferring all or
         substantially  all of its assets to, another  corporation
which assumes
         the Plan and all  obligations  of AT&T  hereunder.  AT&T
agrees that it
         will make  appropriate  provision for the preservation of
the rights of
         Participants,  employees and surviving lawful spouses
under the Plan in
         any  agreement  or plan or  reorganization  into  which
it may enter to
         effect any merger, consolidation, reorganization or
transfer of assets.
         Upon such a  merger,  consolidation,  reorganization,
or  transfer  of
         assets and  assumption  that results in a Participant
continuing to be
         employed  by  the  Company  or  an  Affiliated
Corporation,  the  term
         "Participating  Company" shall refer to such other
corporation and the
         Plan shall continue in full force and effect as to that
Participant and
         his or her lawful spouse or other beneficiary.

9.02.    Fiduciary Relationship.

         Nothing  contained  in the Plan,  and no action  taken
pursuant to the
         provisions of the Plan,  shall create or be construed to
create a trust
         or contract of any kind, or a fiduciary  relationship
between or among
         AT&T, any other Participating Company, any Affiliated
Corporation,  the
         Board, the Administrator, the Committee, any Participant,
employee, any
         surviving lawful spouse or any other person.

9.03.    No Guarantee of Employment.

         Neither the Plan nor any action taken  hereunder  shall
be construed as
         (i) a contract of  employment  or deemed to give any
employee the right
         to be retained in the employment of a Participating
Company, the right
         to any level of compensation,  or the right to future
participation in
         the Plan; or (ii) affecting the right of the
Participating  Company to
         discharge or dismiss any employee at any time.



<PAGE>



9.04.    Tax Withholding.

         AT&T shall withhold all federal,  state,  local or other
taxes required
         by law to be withheld from payments or accruals under the
Plan.

9.05.    Assignment of Benefits.

         The benefits payable  hereunder or the right to receive
future benefits
         under the Plan may not be anticipated,  alienated,
sold,  transferred,
         assigned,  pledged,  executed  upon,  encumbered,  or
subjected to any
         charge or legal process;  no interest or right to receive
a benefit may
         be taken, either voluntarily or involuntarily,  for the
satisfaction of
         the debts of, or other  obligations or claims  against,
such person or
         entity,  including  without  limitation,  any  judgment
or  claim  for
         alimony,  support  or  separate  maintenance  pursuant
to  a  domestic
         relations  order  within the meaning of Section
206(d)(3) of ERISA and
         claims in bankruptcy proceedings.  Any such attempted
disposition shall
         be null and void.

9.06.    Facility of Payment.

         If the  Administrator  shall find that any person to whom
any amount is
         or was payable  under the Plan is unable to care for his
or her affairs
         because of illness or accident,  then any payment, or any
part thereof,
         due to such person  (unless a prior claim  therefor  has
been made by a
         duly appointed  legal  representative),  may, if the
Administrator  so
         directs  AT&T,  be paid to the  same  person  or
institution  that the
         benefits with respect to such person are paid under the
Pension Plan if
         applicable, or to the Participant's surviving lawful
spouse, a child, a
         relative, an institution  maintaining or having custody
of such person,
         or to any  other  person  deemed  by the  Administrator
to be a proper
         recipient on behalf of such person otherwise  entitled to
payment.  Any
         such payment  shall be in complete  discharge of the
liability of AT&T,
         the Board,  the Committee,  the  Administrator,  and the
Participating
         Company therefor.  If any payment to which a Participant
or beneficiary
         is entitled  under this Plan is unclaimed  or otherwise
not subject to
         payment to the person or persons so entitled, such
amounts representing
         such payment or payments shall be forfeited after a
period of two years
         from the date the first such  payment was payable and
shall not escheat
         to any state or revert to any party;  provided,  however,
that any such
         payment or payments shall be restored if any person
otherwise  entitled
         to such payment or payments makes a valid claim.

9.07.    Severability.

         If any section,  clause,  phrase,  provision or portion
of this Plan or
         the application  thereof to any person or circumstance
shall be invalid
         or unenforceable  under any applicable law, such event
shall not affect
         or render invalid or unenforceable the remainder of this
Plan and shall
         not  affect the  application  of any  section,  clause,
provision,  or
         portion hereof to other persons or circumstances.

9.08.    Effective Date.

         This Plan first became effective for Officers  actively
employed on or
         after October 1, 1980 and for E-band Employees  actively
employed on or
         after on January 1, 1984 and is amended and restated
effective January
         1, 1995.

9.09.    Plan Year.

         For purposes of  administering  the Plan,  the plan year
shall begin on
         January 1 and end on December 31.

9.10.    Headings.

         The captions of the  preceding  sections and articles
hereof have been
         inserted  solely as a matter of convenience and shall not
in any manner
         define or limit the scope or intent of any provision of
the Plan.

9.11.    Governing Law.

         To the  extent  such laws are not  preempted  by the laws
of the United
         States of America,  the Plan shall be governed by the
laws of the State
         of New Jersey, except as to its principles of conflict of
laws.

9.12.    Forfeiture of Benefits.

         Except as provided in this  Section  9.12 and  Section
3.02,  benefits
         previously  awarded may not be canceled and,  upon
attaining the right
         under the Plan for an immediate  service benefit or
deferred benefit or
         for an automatic survivor annuity,  such right shall be
nonforfeitable.
         Notwithstanding  any  eligibility  or  entitlement  to
benefits  of an
         individual  arising or conferred under any other
provision or paragraph
         of this Plan, all benefits for which a Participant
would  otherwise be
         eligible hereunder may be forfeited,  at the discretion
of the Board or
         the  Committee,   if  an  individual   without  the
Company's  consent
         establishes a relationship  with a competitor of the
Company or engages
         in activity in conflict with or adverse to the interests
of the Company
         under  the  standards  of the  AT&T  Non-Competition
Guideline  and as
         determined by the Board or the Committee in its sole
discretion.

9.13.    Option During Disability.

         If an employee who has left the service of a
Participating  Company has
         elected to continue receiving  disability  benefits which
he or she had
         been receiving  prior to his or her  termination and to
defer receiving
         pension payments under the Pension Plan to which he or
she is eligible,
         benefits  under  the Plan  shall be  deferred  until
such  time as the
         employee begins to receive payments under the Pension
Plan.

9.14.    Special Classification.

         For purposes of the Plan,  the  determination  of those
causes of death
         not  classified as due to accident  shall be
accomplished  in the same
         manner as set forth in the Pension Plan.

9.15.    Claims Release.

         In case of  accident  resulting  in the  death of a
Participant  which
         entitles  his or her  beneficiaries  or his or her
annuitant  to death
         benefits under the Plan, such  beneficiaries or annuitant
shall,  prior
         to the  payment of any such  benefits,  sign a release,
releasing  the
         Company  or other  Participating  Companies,  as
applicable,  from all
         claims  and  demands  which  the  deceased  had  and
which  his or her
         beneficiaries or his or her annuitant may have against
them,  otherwise
         than under the Plan, on account of such accident.  If any
persons other
         than the  beneficiaries  under this Plan might  legally
assert  claims
         against  a  Participating  Company  on  account  of  the
death  of the
         individual, no part of the death benefit under the Plan
shall be due or
         payable  until there have also been  delivered to the
Committee or the
         Administrator,  as  applicable,  good and  sufficient
releases  of all
         claims,  arising  from or growing  out of the death of
the  individual,
         which such other persons might legally assert against any
Participating
         Company.  The Committee or the  Administrator,  as
applicable,  in its
         discretion, may require that the releases described above
shall release
         any other company connected with the accident, including
the Company or
         any other Participating  Company, as applicable.  This
requirement of a
         release or releases  shall not apply in the case of
Survivor  Annuities
         as described in Section 4.02(d).

9.16.    Damage Claims or Suits.

         Should a claim other than under the Plan be  presented
or suit brought
         against the Company or any Participating Company for
damages on account
         of death of a  Participant,  nothing shall be payable
under the Plan on
         account of such death  except as  provided in Section
9.17;  provided,
         however, that the Committee or the Administrator,  as
applicable,  may,
         in its discretion  and upon such terms as it may
prescribe,  waive this
         provision if such claim be  withdrawn or if such suit be
discontinued;
         and provided further that this provision shall not
preclude the payment
         of Survivor Annuities as described in Section 4.02(d).

9.17.    Judgment or Settlement.

         In case any judgment is recovered against any
Participating  Company or
         any  settlement is made of any claim or suit on account
of the death of
         a Participant,  and the amount paid to the beneficiaries
who would have
         received benefits under the Plan is less than what would
otherwise have
         been payable  under the Plan,  the  difference  between
the two amounts
         may,  in the  discretion  of the  Committee  or the
Administrator,  as
         applicable, be distributed to such beneficiaries.

9.18.    Payment under Law.

         In the case of any benefit  (which the Committee or the
Administrator,
         as applicable, shall determine to be of the same general
character as a
         payment provided by the Plan)that is payable to any
Participant, to his
         or her  beneficiaries,  his or her estate or his or her
annuitant under
         any law now in force or hereafter enacted,  only the
excess, if any, of
         the amount  prescribed  in the Plan  above the  amount of
such  payment
         prescribed by law shall be payable under the Plan;
provided,  however,
         that no  benefit  payable  under the Plan shall be
reduced by reason of
         any  governmental  benefit  or pension  payable on
account of  military
         service  or by  reason of any  benefit  which  the
recipient  would be
         entitled  to  receive  under  the  Social   Security
Act  or  Railroad
         Retirement  Act. In those cases where,  because of
differences  in the
         beneficiaries  or in the time or methods of payment or
otherwise,  the
         determination  of  any  such  excess  is  not
ascertainable  by  mere
         comparison  but  adjustments  are  necessary,   the
Committee  or  the
         Administrator,  as  applicable,  shall,  in its
discretion,  determine
         whether or not in fact any such excess exists and make
the  adjustments
         necessary to carry out in a fair and equitable manner the
spirit of the
         provision for the payment of any such excess.  Further,
in determining
         whether or not there is an excess, to the extent any
payments under any
         law are considered in  determining  whether there is any
excess payable
         to an  employee  under  any  other  comparable  plan
sponsored  by the
         Company,  the amount of such payments under law shall not
be considered
         under this Plan.

9.19.    Entire Plan.

         This written Plan document is the final and exclusive
statement of the
         terms of this  Plan,  and any claim of right or
entitlement  under the
         Plan shall be determined in accordance with its
provisions  pursuant to
         the procedures  described in Article 7. Unless otherwise
authorized by
         the Board or its delegate,  no amendment or
modification  to this Plan
         shall be  effective  until  reduced to writing and
adopted  pursuant to
         Section 8.02.

Prior Pension Formulas


         The pension formulas in effect for retirements  between
the period from
         August 10, 1980 to April 14, 1991,  inclusive,  are
outlined below. The
         Basic  Formula  shown  in Part  1.  applies  solely  to
Officers;  the
         Alternate  Formula in Part 2. applies to all
participants  for service
         benefit  purposes  only,  and an Officer  is  entitled
to the  greater
         benefit provided under either the Basic Formula or
Alternate Formula.


Part 1 - Basic Formula:


         The  product of one and six tenths  percentum  (1.6%) and
an  Officer's
         Adjusted  Career  Income.  The  early  retirement
discounts  shown  is
         Paragraphs  3(b)(ii)  and  4(b)(i)  of  Section 4 of the
Plan  apply to
         pension benefits under this Formula.


         "Adjusted Career Income" is calculated in two steps:


         Step 1 - Determine  the  average of the amount of short
term  incentive
         awards or standard  awards up to a permitted  maximum
amount which were
         paid or effective  during a specified pay base period and
multiply this
         average amount by Term of Employment completed as of the
end of the pay
         base period;


         Step 2 - Total the amount of the  applicable  awards
after the pay base
         period to retirement and add this amount to the amount
calculated under
         Step 1.


         The  components  of the adjusted  career income
calculation  are shown
         below:

Part 2 - Alternate Formula:


Provisions applicable from January 2, 1984 through May 30, 1988


The  following  Alternate  Formula was  effective  for  retirements  on or after
January 2, 1984 through May 30. 1988:


     A.  The product of one and two-tenths  percentum (1.2%) and
Adjusted Career
         Average Pay,


                                      PLUS


     B.  Ten dollars ($10.) and the product of  five-hundredths
percentum (.05%)
         and the difference between the Covered Compensation  Base
for the  year
         of retirement and the Adjusted Career Average Pay.


                                      TIMES


     C.  Term of employment at retirement,


                                      MINUS


     D.  Annual Service  pension payable under the Pension Plan
before reduction
         for a Survivor Annuity or early retirement.


                  The early retirement  discount described in Appendix C of this
Plan applies to the amounts computed under the Alternate Formula.


                  "Adjusted  Career  Average  Pay" in the case of
an  Officer is
                  calculated  by dividing the sum of the total
Adjusted  Career
                  Income  under  the  Basic  Formula  of this
Plan in effect at
                  retirement  and the total  Adjusted  Career
Income  under the
                  Pension Plan formula in effect at retirement by
such Officer's
                  Term of Employment at retirement.


                  "Adjusted  Career  Average  Pay"  for an
E-band  Employee  is
                  Calculated by dividing the total Adjusted
Career Income under
                  the  Pension  Plan  formula  in effect at
retirement  by such
                  employee's Term of Employment at retirement.




<PAGE>



Provisions applicable from May 31, 1988 through October 18, 1993


The following  Alternate  Formula was effective for  retirements on or after May
31, 1988 through October 18. 1993:


     A.  The  product  of  one and  seven-tenths  percentum (1.7%)
and  Adjusted
         Career Average Pay,


                                      MINUS


     B.  The product of eight-tenths (0.8%) and the Covered
Compensation Base,


                                      TIMES


     C.  Term of employment at retirement,


                                      MINUS


     D.  Annual Service pension payable under  the Pension Plan
before reduction
         for a Survivor Annuity or early retirement.


                  The early retirement  discount described in Appendix C of this
Plan applies to the amounts computed under the Alternate Formula.


                  "Adjusted  Career  Average Pay" is  calculated
by dividing the
                  sum of the  total  Adjusted  Career  Income
under  the  Basic
                  Formula  of this Plan in effect  at  retirement
and the total
                  Adjusted  Career  Income  under the  Pension
Plan  formula in
                  effect at retirement by such  Officer's  Term of
Employment at
                  retirement.


Part 3 - Waiver of Death Benefit


         Waiver of the Death Benefit. If an Officer is deemed to
have waived the
         death  benefit under the Pension Plan, he or she will be
deemed to have
         waived such death benefits  pursuant to this Plan as
well,  provided he
         or she  either  died  before  January  1, 1987 or he or
she  retired or
         terminated  employment before December 31, 1986 and had
attained age 55
         on or before  December  31,  1983;  if a prior  waiver by
an Officer of
         death  benefits  under the Pension Plan is deemed
rescinded  under the
         Pension Plan, such waiver is deemed rescinded under this
Plan effective
         December 31, 1986.

              AT&T SENIOR MANAGEMENT INCENTIVE AWARD DEFERRAL PLAN
                         (as amended December 20, 1995)


1.       ELIGIBILITY

         Any Senior  Manager  (as  defined in the AT&T 1987 Long
Term  Incentive
Program [the "1987 Plan"]) of American  Telephone and Telegraph Company ("AT&T")
or an Affiliate (as defined in the 1987 Plan) who is eligible for an award under
the AT&T Short Term Incentive Plan (the "Short Term Incentive  Plan") and/or who
has been granted a Performance Award or a Stock Unit Award under the AT&T Senior
Management Long Term Incentive Plan (the "Long Term Incentive Plan") or the 1987
Plan,  or who is eligible  for an award under the AT&T  Paradyne  GMT Short Term
Incentive Plan (the "Paradyne  Plan"),  shall be eligible to participate in this
AT&T Senior Management  Incentive Award Deferral Plan (the "Plan"). For purposes
of the Plan,  AT&T and any  Affiliate  shall be referred to as a  "Participating
Company".  Prior to January 1, 1984,  the Plan was named the Bell System  Senior
Management Incentive Award Deferral Plan.


2.       PARTICIPATION

         (a) Prior to the beginning of any calendar year, any Senior Manager may
elect to participate in the Plan by directing that (i) all or part of the awards
under the Short Term  Incentive  Plan or the Paradyne  Plan, or the  Performance
Awards or the Stock Unit Awards under the Long Term  Incentive  Plan or the 1987
Plan and/or (ii) all or part of the dividend  equivalent payments under the Long
Term  Incentive  Plan or the 1987  Plan,  which  such  employee's  Participating
Company would otherwise pay currently to such employee in such calendar year and
subsequent  calendar years,  shall be credited to a deferred  account subject to
the terms of the Plan. However, in no event shall the part of an award under any
plan credited during any calendar year be less than $1,000 (based on a valuation
at the time the award would  otherwise be paid).  There shall be no such minimum
limitation  on amounts  credited  during any  calendar  year that are related to
dividend equivalent payments.

         In addition,  prior to the beginning of any calendar year, the Chairman
of the Board and any other  Senior  Manager  designated  by the  Chairman of the
Board may elect to participate in the Plan by directing that all or part of such
Senior  Manager's  salary,  which such  employee's  Participating  Company would
otherwise pay  currently to such  employee in such calendar year and  subsequent
calendar years,  shall be credited to a deferred account subject to the terms of
the Plan.

         (b) Such an election to participate in the Plan shall be in the form of
a document executed by the employee and filed with the employee's  Participating
Company.  An election related to awards,  dividend  equivalent  payments and/ or
salary otherwise payable currently in any calendar year shall become irrevocable
on the last day prior to the beginning of such calendar year.

         (c) An  election  shall  continue  until  the  employee  terminates  or
modifies such election by written notice.  Any such  termination or modification
shall become  effective as of the end of the calendar  year in which such notice
is  given  with  respect  to all  awards,  dividend  equivalents  and/or  salary
otherwise payable in subsequent calendar years.

         (d) An eligible  employee who has filed a  termination  of election may
thereafter  again  file an  election  to  participate  with  respect  to awards,
dividend  equivalent  payments and/or salary otherwise payable in calendar years
subsequent to the filing of such election.


3.       DEFERRED ACCOUNTS

         (a)  (i)  Deferred  amounts  related  to  awards,  dividend  equivalent
payments which would otherwise have been  distributed in cash by a Participating
Company  and  deferred  amounts  related  to  salary  shall be  credited  to the
employee's  account and shall bear interest  from the date the awards,  dividend
equivalent  payments  and/or salary would otherwise have been paid. The interest
credited to the account will be compounded at the end of each calendar  quarter,
and the annual rate of interest applied at the end of any calendar quarter shall
be determined by the AT&T Board of Directors from time to time.

                  (ii) Furthermore, if an employee made an election described in
Section  2, which  election  was  effective  on  December  31,  1983,  then such
employee's  account  shall also be credited  during 1984 with an amount equal to
the deferred  amounts which would have been credited to the  employee's  account
during 1984 had the company  which  employed  the  employee on December 31, 1983
continued to be a Participating  Company during 1984, and such amount shall bear
interest in  accordance  with (a)(i)  above from the date such amount would have
been credited had such company  continued to be a  Participating  Company during
1984.

         (b) Deferred  amounts related to awards which would otherwise have been
distributed in AT&T common shares by a  Participating  Company shall be credited
to the employee's account as deferred AT&T shares.  Furthermore,  if an employee
made an  election  described  in Section  2, which  election  was  effective  on
December 31, 1983,  then such  employee's  account shall also be credited during
1984 with the  deferred  AT&T  Shares  which  would  have been  credited  to the
employee's  account had the company which  employed the employee on December 31,
1983  continued to be a  Participating  Company in the Plan and in the Long Term
Incentive  Plan during 1984.  The  employee's  account shall also be credited on
each  dividend  payment  date for AT&T shares with an amount  equivalent  to the
dividend  payable on the  number of AT&T  common  shares  equal to the number of
deferred  AT&T  shares in the  employee's  account on the  record  date for such
dividend. Such amount shall then be converted to a number of additional deferred
AT&T  shares  determined  by  dividing  such  amount by the price of AT&T common
shares, as determined in the following sentence. The price of AT&T common shares
related to any dividend  payment date shall be the average of the daily high and
low sale prices of AT&T common  shares on the New York Stock  Exchange  ("NYSE")
for the period of five trading days ending on such dividend payment date, or the
period of five trading days immediately  preceding such dividend payment date if
the NYSE is closed on the dividend payment date.

         (c) In the event of any change in  outstanding  AT&T  common  shares by
reason of any stock dividend or split, recapitalization,  merger, consolidation,
combination or exchange of shares or other similar  corporate  change,  the AT&T
Board  of  Directors  shall  make  such  adjustments,  if  any,  that  it  deems
appropriate  in the number of deferred  AT&T shares then  credited to employees'
accounts.  Any and all such adjustments shall be conclusive and binding upon all
parties concerned.


4.       DISTRIBUTION

         (a) At the time an eligible  employee  makes an election to participate
in the Plan,  the  employee  shall  also make an  election  with  respect to the
distribution  (during the employee's  lifetime or in the event of the employee's
death) of the  amounts  credited to the  employee's  deferred  account.  Such an
election related to the distribution during the employee's lifetime,  of amounts
otherwise  payable  currently in any calendar year, shall become  irrevocable on
the last day prior to the beginning of such calendar year.

         The election related to the distribution in the event of the employee's
death,  including the  designation  of a beneficiary  or  beneficiaries,  may be
changed by the employee at any time by filing the appropriate  document with the
Secretary of the Company.

         Amounts credited as cash plus accumulated interest shall be distributed
in cash;  amounts  credited as deferred AT&T shares shall be  distributed in the
form of an equal number of AT&T shares.

         (b) An  employee  may elect to  receive  the  amounts  credited  to the
employee's account in one payment or in some other number of approximately equal
annual  installments (not exceeding 20),  provided  however,  that the number of
annual  installments  may not extend beyond the life expectancy of the employee,
determined as of the date the first installment is paid. The employee's election
shall also  specify  that the first  installment  (or the single  payment if the
employee  has so  elected)  shall be paid  either  (1) on the  first  day of the
calendar  quarter  next  following  the end of the month in which  the  employee
attains the age specified in such election,  which age shall not be earlier than
age 55 or later than age 70-1/2,  (2) on the first day of the  calendar  quarter
next  following  the end of the  month  in which  the  employee  retires  from a
Participating  Company or otherwise terminates employment with any Participating
Company  (except for a transfer  to another  Participating  Company);  provided,
however, that the AT&T Board of Directors or the Compensation  Committee of such
Board may, in its sole  discretion,  direct that the first  installment  (or the
single payment) shall be paid on the first day of the first calendar  quarter in
the calendar year next following the year of retirement or other  termination of
employment,  or (3) on the  first  day of  the  first  calendar  quarter  in the
calendar year next  following  the calendar  year in which the employee  retires
from a  Participating  Company  or  otherwise  terminates  employment  with  any
Participating Company (except for a transfer to another Participating Company).

         (c)  Notwithstanding  an  election  pursuant to  Paragraph  (b) of this
Section 4, the entire  amount then  credited to an  employee's  account shall be
paid immediately in a single payment (a) if the employee is discharged for cause
by his or her  Participating  Company,  (b) if the  Board of  Directors  of such
Participating  Company  determined  that the employee  engaged in  misconduct in
connection with the employee's employment with the Participating Company, (c) if
the  employee  without  the  consent  of the  Board of  Directors  of his or her
Participating Company, while employed by such Participating Company or after the
termination of such employment, becomes associated with, employed by, or renders
services to, or owns an interest in, any business  that is in  competition  with
any Participating  Company or with any business in which a Participating Company
has a substantial  interest (other than as a shareholder with a  non-substantial
interest  in  such  business),  or  (d)  the  employee  becomes  employed  by  a
governmental  agency having  jurisdiction over the activities of a Participating
Company or any of its subsidiaries.

         (d) An employee may elect that,  in the event the  employee  should die
before full  payment of all  amounts  credited to the  employee's  account,  the
balance of the deferred  amounts shall be  distributed in one payment or in some
other number of approximately  equal annual  installments  (not exceeding 10) to
the beneficiary or beneficiaries designated in writing by the employee, or if no
designation has been made, to the estate of the employee.  The first installment
(or the single  payment if the  employee  has so  elected)  shall be paid on the
first day of the calendar  quarter next following the month of death;  provided,
however, that the AT&T Board of Directors or the Compensation  Committee of such
Board may, in its sole  discretion,  direct that the first  installment  (or the
single payment) shall be paid on the first day of the first calendar  quarter in
the calendar year next following the year of death.

         (e) Installments  subsequent to the first  installment to the employee,
or to a beneficiary or to the employee's estate,  shall be paid on the first day
of the applicable  calendar  quarter in each succeeding  calendar year until the
entire amount credited to the employee's  deferred account shall have been paid.
Deferred  amounts held pending  distribution  shall continue to be credited with
interest or  additional  deferred  AT&T shares,  as  applicable,  determined  in
accordance with Section 3(a) and (b).

         (f) In the event an employee,  or the employee's  beneficiary after the
employee's  death,  incurs  a  severe  financial  hardship,  the  AT&T  Board of
Directors or the  Compensation  Committee of such Board, in its sole discretion,
may  accelerate or otherwise  revise the payment  schedule  from the  employee's
account to the extent  reasonably  necessary to eliminate  the severe  financial
hardship.  For the purpose of this subsection (f), a severe  financial  hardship
must have been caused by an accident, illness, or other event beyond the control
of the employee or, if applicable, the beneficiary.

         (g) The obligation to make a distribution of deferred  amounts credited
to an employee's  account during any calendar year plus the  additional  amounts
credited on such  deferred  amounts  pursuant  to Section  3(a) and (b) shall be
borne by the  Participating  Company which otherwise would have paid the related
award or salary  currently.  However,  the obligation to make  distribution with
respect  to  deferred  amounts  which are  related  to  amounts  credited  to an
employee's  account  under  Section  3(a)(ii)  and under the second  sentence of
Section 3(b), and with respect to which no Participating Company would otherwise
have  paid the  related  award  currently,  shall be borne by the  Participating
Company which employed the employee on January 1, 1984.


5.       MISCELLANEOUS

         (a) The  deferred  amounts  shall be held in the  general  funds of the
Participating  Companies.  The Participating  Companies shall not be required to
reserve, or otherwise set aside, funds for the payment of such amounts.

         (b)  The  rights  of an  employee  to any  deferred  amounts  plus  the
additional  amounts  credited  pursuant  to  Section  3(a) and (b)  shall not be
subject to assignment by the employee.

         (c) The Senior Vice President - Human  Resources of AT&T shall have the
authority to administer and to interpret the Plan.

         (d) The AT&T  Board of  Directors  may at any  time  amend  the Plan or
terminate the Plan, but such amendment or termination shall not adversely affect
the rights of any employee, without his or her consent, to any benefit under the
Plan to which such employee may have  previously  become  entitled  prior to the
effective date of such amendment or termination. The Senior Vice President Human
Resources of AT&T with the  concurrence of the Senior Vice President and General
Counsel of AT&T shall be authorized to make minor or  administrative  changes to
the Plan, as well as amendments  required by applicable federal or state law (or
authorized or made desirable by such statutes).

         No  service,  disability,  or deferred  benefit  under this Plan or any
right or interest in such  service,  disability,  or deferred  benefit  shall be
assignable or subject in any manner to anticipation, alienation, sale, transfer,
claims of creditors,  garnishment,  pledge, execution, attachment or encumbrance
of any kind,  including,  but not limited to, pursuant to any domestic relations
order (within the meaning of ERISA ss.  206(d)(3) and Code ss.  414(p)(1)(B)) or
judgment or claims for alimony,  support,  separate  maintenance,  and claims in
bankruptcy  proceedings,  and any such attempted  disposition  shall be null and
void.

 5.3.     Breaks in Service

         For  purposes  of this Plan a break in  service  shall be  defined  and
treated in the same manner as is set forth in the Pension Plan.

 5.4.     Leave of Absence

         For  purposes  of this Plan,  a leave of absence  shall be defined  and
administered in the same manner as is set forth in the Pension Plan.

 5.5.     Method of Payment

         Payments  under  this Plan  shall be made in the same  manner as is set
forth under the Pension Plan.

 5.6.     Amounts Accrued Prior to Death

         Benefit amounts accrued but not actually paid at the time of death of a
former  employee or retiree shall be paid in  accordance  with the standards and
procedures set forth in the Pension Plan.

 5.7.     Facility of Payment

         If the  Administrator  shall find that any person to whom any amount is
or was payable  under the Plan is unable to care for his or her affairs  because
of illness or  accident,  then any  payment,  or any part  thereof,  due to such
person (unless a prior claim  therefor has been made by a duly  appointed  legal
representative),  may, if the  Administrator so directs the Company,  be paid to
the same person or  institution  that the benefit with respect to such person is
paid or to be paid  under  the  Pension  Plan,  or to the  Participant's  lawful
spouse,  a child, a relative,  or  institution  maintaining or having custody of
such person,  or any other  person  deemed by the  Administrator  to be a proper
recipient  on behalf of such person  otherwise  entitled  to  payment.  Any such
payments made pursuant to this Section 5.7 shall be in complete discharge of the
liability of the Company, the Board, the Committee,  the Administrator,  and the
Participating  Company  therefor.  If any  payment  to  which a  Participant  or
beneficiary is unclaimed,  such payment shall be forfeited after a period of two
years from the date the first such  payment was payable and shall not escheat to
any state or revert to any party;  provided,  however,  that any such payment or
payments shall be restored if any person  otherwise  entitled to such payment or
payments makes a valid claim.

 5.8.     Option During Disability

         For an employee who has left the service of a Participating Company and
has elected to continue receiving  disability  benefits which he or she had been
receiving  prior to his or her termination of employment  (including  disability
benefits  under the AT&T  Senior  Manager  Long  Term  Disability  and  Survivor
Protection Plan) and to defer receiving  pension payments under the Pension Plan
to which he or she is eligible, benefits under this Plan shall be deferred until
such time as the employee begins to receive payments under the Pension Plan.

 5.9.     Payments Under Law

         In case any benefit  which the Committee  shall  determine to be of the
same general  character  as a payment  provided by the Plan that is payable to a
former  employee  of a  Participating  Company  under  any law now in  force  or
hereafter enacted, the excess only, if any, of the amount prescribed in the Plan
the amount of such payment  prescribed  by law shall be payable  under the Plan;
provided,  however,  that no benefit payable under this Plan shall be reduced by
reason of any  governmental  benefit or pension  payable on account of  military
service,  or by reason of any benefit which the  recipient  would be entitled to
receive under the Social  Security Act or the Railroad  Retirement Act. In those
cases where, because of differences in the beneficiaries,  or differences in the
time or methods of payment, or otherwise, whether or not there is such excess is
not  ascertainable  by  mere  comparison  but  adjustments  are  necessary,  the
Committee  has  discretion  to determine  whether or not in fact any such excess
exists  and to  make  the  adjustments  necessary  to  carry  out in a fair  and
equitable  manner the spirit of the  provision  for the payment of such  excess.
Further,  in  determining  whether or not there is an excess,  to the extent any
payments under any law are considered in determining whether there is any excess
payable to an employee under the Pension Plan, the amount of such payments under
law shall not be considered under this Plan.

 5.10.    Binding Effect

         The  Plan  shall be  binding  upon and  inure  to the  benefit  of each
Participating  Company and its successors and assigns,  and to each Participant,
his or her successors,  designees,  beneficiaries,  designated  annuitants,  and
estate.  The Plan  shall  also be  binding  upon any  successor  corporation  or
organization  succeeding  to  substantially  all of the assets and business of a
Participating  Company.  Nothing  in the Plan  shall  preclude  a  Participating
Company from merging or  consolidating  into or with, or  transferring  all or a
portion of all of its assets to, another corporation which assumes the Plan or a
portion of the Plan and all or a portion of the  obligations of a  Participating
Company  hereunder.   Each  Participating  Company  agrees  that  it  will  make
appropriate  provision for the  preservation of the rights of  Participants  and
beneficiaries  under the Plan in any  agreement or plan or  reorganization  into
which it may enter to effect  any  merger,  consolidation,  reorganization  into
which it may enter to  effect  any  merger,  consolidation,  reorganization,  or
transfer  of  assets.  Upon such a  merger,  consolidation,  reorganization,  or
transfer of assets, the term  "Participating  Company" shall refer to such other
corporation and the Plan shall continue in full force and effect.

 5.11.    Severability

         If any section,  clause, phrase,  provision, or portion of this Plan or
the  application  thereof  to any  person or  circumstance  shall be  invalid or
unenforceable  under any  applicable  law, such event shall not affect or render
invalid or  unenforceable  the  remainder  of this Plan and shall not affect the
application  of any  section,  clause,  provision,  or  portion  hereof to other
persons or circumstances.

 5.12.    Headings

         The captions  preceding  the  sections  and  articles  hereof have been
inserted solely as a matter of convenience and shall not in any manner define or
limit the scope or intent of any provisions of the Plan.

 5.13.    Entire Plan

         This written Plan document is the final and exclusive  statement of the
terms of this Plan, and any claim of right or  entitlement  under the Plan shall
be determined  in  accordance  with its  provisions  pursuant to the  procedures
described  in  Article  3.  Unless  otherwise  authorized  by the  Board  or its
delegate,  no amendment or  modification  to this Plan shall be effective  until
reduced to writing and adopted pursuant to Section 6.1.

                              6. Plan Modification

 6.1.     Amendment and Termination

         Pursuant to ERISA ss.  402(b)(3),  the Board or its  delegate,  (acting
pursuant to the Board's  delegations  of authority then in effect) may from time
to time  amend,  modify  or  change  the Plan at any  time as set  forth in this
document,  and  the  Board  or its  delegate  (acting  pursuant  to the  Board's
delegations  of authority  then in effect) may  terminate  the Plan at any time.
Plan amendments may include, but are not limited to, elimination or reduction in
the level or type of benefits provided to employees. Any and all Plan amendments
may be made without the consent of any employee.  Notwithstanding the foregoing,
no such  amendment,  suspension or  termination  shall  retroactively  impair or
otherwise adversely affect the accrued benefit of any employee as of the date of
such action.

                              7. Source of Payment

 7.1.     Source of Payments

         Benefits arising under this Plan and all costs,  charges,  and expenses
relating thereto will be payable from the Company's general assets.  The Company
may,  however,  establish a trust to pay such  benefits  and  related  expenses,
provided such trust does not cause the Plan to be "funded" within the meaning of
ERISA.  To the  extent  trust  assets  are  available,  they  may be used to pay
benefits arising under this Plan and all costs,  charges,  and expenses relating
thereto.  To  the  extent  that  the  funds  held  in the  trust,  if  any,  are
insufficient  to pay such  benefits,  costs,  charges and expenses,  the Company
shall pay such benefits,  costs,  charges, and expenses from its general assets.
In addition,  the Company may, in its sole  discretion,  purchase and distribute
one or more commercial annuity  contracts,  or cause the trustee of the trust to
purchase  and  distribute  one or more  commercial  annuity  contracts,  to make
benefit payments required under this Plan, to any Senior Manager,  as defined in
the AT&T  Non-Qualified  Pension  Plan,  or the  Surviving  Spouse of any Senior
Manager,  provided,  however,  that the  purchase and  distribution  of any such
annuity  contracts  shall be no sooner  than the  expiration  of any  forfeiture
provisions  applicable  to the  Senior  Manager  under the AT&T  Non-Competition
Guidelines.  Such annuity  contracts may be purchased from a commercial  insurer
acceptable to the  Executive  Vice  President - Human  Resources.  Further,  the
Executive  Vice  President  -  Human  Resources,  may  determine,  in  his  sole
discretion,  to pay additional  sums to any Senior  Manager,  from the Company's
general  assets or from the trust,  if any, to reimburse the Senior  Manager for
additional  federal and state income taxes estimated to be incurred by reason of
the  distribution  of any such annuity  contracts.  The Executive Vice President
Human Resources shall establish a methodology or  methodologies  for determining
the amount of such additional  sums. The methodology or  methodologies  selected
shall be those that the Executive Vice President - Human  Resources  determines,
in his sole discretion,  to be the most effective and administratively  feasible
for  the  purpose  of  producing  after  tax  periodic   benefit  payments  that
approximate  the  after tax  periodic  benefit  payments  that  would  have been
received by Senior  Managers in the absence of the  distribution  of the annuity
contract.

 7.2.     Unfunded Status

         The Plan at all times shall be entirely  unfunded  for  purposes of the
Code and  ERISA  and no  provision  shall at any time be made  with  respect  to
segregating  any assets of a  Participating  Company for payment of any benefits
hereunder.  Funds that may be invested  through a trust described in Section 7.1
shall  continue  for  all  purposes  to be  part of the  general  assets  of the
Participating  Companies which invested the funds.  The Plan  constitutes a mere
promise by the Participating  Companies to make benefit payments under this Plan
in the future.  No Participant  shall have any interest in any particular assets
of a Participating Company by reason of the right to receive a benefit under the
Plan and to the extent  the  Participant  acquires  a right to receive  benefits
under this Plan,  such right shall be no greater than the right of any unsecured
general creditor of a Participating Company.

 8.1.     Sale, Spin-Off, or Other Disposition of Participating
Company

         (a)......Subject to Section 5.10, in the event the Company sells, spins
off, or otherwise  disposes of a Subsidiary  or an  Affiliated  Corporation,  or
disposes  of  all or  substantially  all of the  assets  of a  Subsidiary  or an
Affiliated  Corporation such that one or more Participants  terminate employment
for the purpose of  accepting  employment  with the  purchaser  of such stock or
assets,  any person  employed by such  Subsidiary or Affiliated  Corporation who
ceases to be an employee as a result of the sale, spin-off, or disposition shall
be deemed to have terminated his or her employment with a Participating  Company
and be eligible for a Mid-Career  Pension benefit commencing at the same time as
his or her benefit, if any, commences under the Pension Plan.

         (b)......Notwithstanding  the foregoing provisions of this Section 8.1,
and  subject  to  Section  5.10,  if,  as part of the sale,  spin-off,  or other
disposition  of the stock or assets of a Subsidiary or  Affiliated  Corporation,
the  Subsidiary or Affiliated  Corporation,  its successor  owner,  or any other
party  agrees  in  writing  to  assume  the  liability  for the  payment  of the
Mid-Career  Pension  benefit to which the  Participant  would have been entitled
under  the Plan but for such  sale,  spin-off,  or other  disposition,  then the
entitlement of the  Participant to a Mid-Career  Pension benefit under this Plan
shall  terminate.  Any subsequent  entitlement of the former  Participant to the
Mid-Career  Pension  benefit  shall be the sole  responsibility  of the assuming
party.  Upon the  assumption  of the  liability  for the payment of a Mid-Career
Pension  benefit by Lucent  Technologies  Inc.  pursuant  to Section  7.1 of the
Management Interchange Agreement or Section 3.1 of the Occupational  Interchange
Agreement,  both dated as of April 8, 1996, between Lucent Technologies Inc. and
AT&T Corp.,  the  entitlement of a Transition  Individual (as defined in Section
1.38(b) or (c) of the Management Interchange Agreement or Section 1.30(b) or (c)
of the  Occupational  Interchange  Agreement),  to a Mid-Career  Pension benefit
under this Plan shall terminate.

Program Overview

The Senior  Management  Basic Life Insurance  Program (SMBLIP) is an arrangement
where the Company and you  purchase a permanent  life  insurance  policy on your
life. SMBLIP replaces the pre-age 65 one times salary rounded to the next higher
$1,000 death benefit  provided  under the AT&T Corp.  Basic Group Life Insurance
Plan.

The Company pays the annual  premium.  Your W-2 will  reflect an imputed  income
amount associated with the insurance  coverage provided to you under the policy.
In certain cases, e.g., your death before retirement, the total benefits will be
shared between the Company and your designated  beneficiary but the Company will
share in the death  benefit only to the extent that the total  insurance  amount
exceeds one times your salary rounded to the next highest  $1,000.  This type of
arrangement is known in the insurance industry as "Split Dollar."

After attaining normal retirement (age 65) or, if later, 10 years (in some cases
it may be longer to avoid violation of the Internal Revenue Service  Regulations
Section 7702 guidelines)  from the date of issuance of this policy,  the Company
will recoup its premium  payments from the cash value build-up and cease to have
any  interest in the policy.  The  remaining  cash value will be  sufficient  to
maintain your death benefit without further premium payments.

As in the Basic Group Life  Insurance  Plan,  your death  benefit will change to
reflect any change in your salary. At retirement, your death benefit will become
frozen at your final annual salary rounded to the next higher $1,000. During the
period in which the Company makes  premium  payments,  your imputed  income will
increase  to reflect  your  increasing  age,  as well as any  increase  in death
benefit.  Your imputed  income will be lower than under the current  Basic Group
Life  Insurance  Plan  because  it will be  based  on the  insurers'  term  life
insurance  rates,  which are lower  than the  corresponding  federal  government
standard rates for group insurance.  After premium payments  discontinue,  i.e.,
the later of your  attaining  age 65 or 10 years (in some cases it may be longer
to avoid  violation of the Internal  Revenue  Service  Regulations  Section 7702
guidelines) from the policy issue date, you will have no further imputed income.

Although  this  arrangement  is  primarily  designed to pay a benefit  upon your
death,  there  is  also  a cash  value  build-up.  Once  sufficient  funds  have
accumulated  and the Company no longer has an interest in the policy  because it
has  recouped  its  premiums,  you  have  the  option  to use some or all of the
remaining cash in lieu of some or all of the death benefit.

AT&T Corp.  has selected two insurers to provide the SMBLIP  coverage.  You will
therefore  have two  policies  on your  life;  one from each  insurer,  and each
insurer will provide half the defined amount of death benefit on
your life.






Eligibility

SMBLIP is for active AT&T Corp. Senior Managers.  Employees who
are  promoted to
or hired as Senior Managers are immediately eligible to enroll in
this program.


Coverage

SMBLIP is provided as a  replacement  to the death benefit  coverage  associated
with the Basic  Group Life  Insurance  Plan.  The  benefit  is one times  salary
rounded to the next higher $1,000.

The death benefit will be updated to reflect  changes in your salary.  There may
be  circumstances   where  a  large  increase  in  salary  and,   therefore,   a
corresponding   increase  in  death  benefit,  will  require  providing  medical
information to the insurer. By providing this medical  information,  the insurer
is able to keep the premium payments at the lowest level. A medical  information
waiver,  signed  by you,  will be kept on file in the  event  this  circumstance
occurs.  This will allow the Company to release,  to the  insurer,  the required
information  from your Company medical  records.  Higher death benefit  coverage
associated  with  salary  increases  is  guaranteed,  no matter what your health
circumstances may be at that time.


Conversion Rights

If you were a participant  in the AT&T Corp.  Basic Group Life Insurance Plan at
the time you became  eligible for SMBLIP,  for a limited period of time you have
the right to  convert  your  coverage  under the Basic  Group Plan to a separate
individual  policy  provided  by the group  insurance  carrier.  We suggest  you
discuss this with your  financial  advisor  before  exercising or declining this
right.  You may exercise this right by contacting your Executive Human Resources
Consultant  or  Rosemarie   Wolfstromer   at   Metropolitan   Life  directly  on
201-712-5463.


Program Illustration

Included  as an  attachment  is a personal  illustration  based on your  current
salary.  This  illustration  shows  your  costs  and  benefits  as  well  as the
Company's,  over the life of the policy. It is provided to give a picture of how
the policy works and what your tax on imputed  income might be, using an assumed
salary growth.  The actual ongoing life insurance amounts will be different from
this illustration.

Imputed Income Rate Comparison with Basic Group Life Insurance

SMBLIP offers a cost-effective life insurance program for Senior Managers,  with
imputed income rates  substantially  below the Basic Group Life rates. (The cost
to you of the  SMBLIP  will be the  income  tax  payable  on the  amount of your
imputed income.)



                  Annual Imputed Income Rate per $1,000 of Life
Insurance

Premium Period

SMBLIP is designed for premiums to be extended over a period of time to ease the
impact on cash flow to the  Company.  This period is  normally  from the time of
your  enrollment  until the  first  policy  anniversary  after you reach age 65.
However,  in all cases,  premiums must be paid for a minimum of 10 years(in some
cases it may be  longer  to avoid  violation  of the  Internal  Revenue  Service
Regulations  Section 7702 guidelines).  Therefore,  if you enroll in the program
after age 55, the Company will continue  premium  payments and you will continue
to recognize income until the minimum is reached.


Cash Value

This  program is designed to provide you with a pre- and post  retirement  death
benefit.  However,  in  addition  to the death  benefit,  there is a cash  value
build-up.  That is, part of each  premium is placed in an  "investment  fund" to
earn income.  Investment  earnings  beyond the amounts  necessary to provide the
death  benefit  coverage  build on a tax  advantaged  basis in the  policy.  The
policy's  cash  value is the  basis for your  subsequent  "premium  free"  death
benefit.




<PAGE>


Cash Availability

Under  SMBLIP you have  considerably  greater  flexibility  than under the Basic
Group Life Insurance Plan.  After the Company  interest has been satisfied,  you
may reduce  your death  benefit and utilize the policy cash value in a number of
ways. For example:

           a) Loans
              The cash value attributed to you may be withdrawn in
the form of a
              loan.  There could be tax  implications  as well as
death  benefit
              diminution associated with a loan.

           b) Income Stream or Lump Sum
              It is  possible to convert all or any portion of the
policy from a
              death benefit to either an income "stream" (i.e., an
annuity) or a
              lump sum cash payout. The extent to which you
convert to income or
              cash will cancel or reduce the death benefit. Once
you convert, it
              is not possible to re-establish the original death
benefit.

We suggest that you speak with your financial  advisor before  exercising  these
options.


Insurability

During the enrollment period you will be guaranteed to be insured.  Your imputed
income rate, however, will not depend on your health or smoking status.  Rather,
it will differ from others depending only on age and amount of
Death  Benefit.
This  enrollment  methodology  also  applies to new Senior  Managers  who enroll
within  60 days of  becoming  a  Senior  Manager.  Enrollment  after 60 days may
require a medical questionnaire or examination.


Transfer of Ownership

As with the Basic Group Life  Insurance  Plan,  after you take  ownership in the
policy,  you may transfer  ownership to anyone you choose,  e.g., an individual,
trust, etc. Since these transfers are generally construed to be irrevocable,  we
urge you to consult  with an  attorney  and/or tax  advisor  before  making this
decision.

Another  option is for you to not take  ownership,  but  rather  another,  e.g.,
individual,  trust,  etc.,  may  apply for  ownership  of the  policy.  It is of
particular  importance that if the original owner of the policy is not you, that
the  owner  should  sign  as the  "Applicant/Owner"  and  you  should  sign  the
application as the "Proposed Insured".


Early Retirement or Termination

If, at retirement,  you are "Pension Eligible" (i.e., you retire on an immediate
Service or Disability  Pension under the AT&T Corp.  Management Pension Plan, or
with a Disability  Allowance or Minimum  Retirement Benefit under the AT&T Corp.
Senior  Management  Long Term Disability and Survivor  Protection  Plan) and you
have not reached  normal  retirement  age (65), the Company will continue to pay
premiums until you reach age 65 or, if later, ten years (in some cases it may be
longer to avoid violation of the Internal  Revenue Service  Regulations  Section
7702 guidelines) from the date of issuance of the policy. During this period you
will  continue  to have  imputed  income  based  on your age and the  amount  of
insurance  in force.  At the end of this period,  i.e.,  the later of the policy
anniversary  immediately  following  your  attainment of age 65 or the tenth (in
some cases it may be longer to avoid  violation of the Internal  Revenue Service
Regulations Section 7702 guidelines) policy anniversary, the premiums will cease
and the aggregate Company premiums will be returned to the Company.

If you separate from the Company without being Pension  Eligible,  the aggregate
amount of Company premiums paid up to that point will be immediately returned to
the Company from the cash value of the policy.  You can, at your option,  either
maintain the policy by paying the policy premiums,  or you may use the remaining
cash value (if any) to buy other  "self-supporting"  life insurance,  or you may
withdraw any remaining cash value and cancel the policy.

Whether or not you are Pension Eligible,  if you leave the Company,  and without
the Company's consent, establish a relationship with a competitor of the Company
or engage in  activity  in  conflict  with or  adverse to the  interests  of the
Company under the standards of the AT&T Corp.  Non-Competition Guidelines and as
determined by the AT&T Corp. Management Executive Committee, the process will be
the same as with retirement/termination without being Pension Eligible.


Demotion

If you are demoted to a position  which is not a Senior  Manager,  the effect is
the same as if  terminated  from the Company.  You will  however,  automatically
become  re-eligible for coverage under the AT&T Corp. Basic Group Life Insurance
Plan.


Contractual Agreement

One of the  unique  aspects  of this  insurance  policy  is the  existence  of a
contract  between you and AT&T Corp..  This  agreement  has no  relationship  to
employment or any other benefit but rather defines the  responsibilities of both
the Company and you in the  operation of the policy.  You, or another,  will own
the policy and  determine  who the  beneficiary  is. The  Company  will hold the
policy and have a "Collateral  Assignment"  from the owner entitling AT&T Corp.,
as long as it has a  collateral  interest  in the policy,  to any death  benefit
amounts in excess of one times your salary,  and all cash values up to an amount
equal to its cumulative premiums paid. This document is a legal agreement and as
such includes a significant  amount of detail and warrants careful review before
signing.  Although somewhat unique to life insurance, a collateral assignment is
similar in context to an automobile loan where the car becomes  "collateral" for
the money  lent to buy it. In this  case,  a portion of the cash value and death
benefit of the policy is the  collateral the Company  receives for  contributing
premium payments to "buy" the life insurance policy.  The agreement is satisfied
when the aggregate premiums paid by the Company are returned.  Some of the major
sections of the agreement are:

                                    -       Description of the
policy
                                    -       How the premiums are
paid
                                    -       How the proceeds are
paid
                                    -       How the agreement
terminates
                                    -       Claims procedure
                                    -       Description of the
assignment

The Agreement is included with this package.


Secured Benefit

Changes to the tax law over the years have  required more and more of the Senior
Management  benefit programs to be paid from Company  operating  income.  SMBLIP
allows the Company to  contribute  towards the cost of this  program on a timely
basis while  securing  the  benefit  payment  from a third party (the  insurance
companies).

Taxes

Split Dollar life insurance policies have been in existence for decades. The IRS
has issued several rulings over this period which treat these policies favorably
from a tax perspective.  However, the Company does not assure any particular tax
treatment and  recommends  that you review your own situation with your personal
attorney and/or tax advisor.


Enrollment

AT&T Corp.  has  selected  two  insurers to provide the coverage for each Senior
Manager.  This was done to provide  the best  combination  of premium  rates and
Senior  Manager  protection.  As  such,  there  may be a  requirement  for  some
duplication  of forms,  signatures,  etc. Once  enrollment  has been  completed,
however, this two insurer approach should have a minimal impact on you.

The  documents  required  for  enrolling  in the  Senior  Management  Basic Life
Insurance Program are included. The Application Forms require, for this program,
just a few basic pieces of information, as do the Beneficiary
Designation forms.
The documents include instructions on how to fill them out.
The Collateral Assignment requires signature only.

After  completing  the forms,  enclose them in the  self-addressed  envelope and
return to the Executive Human Resources Group.



                                     Form of
                              EMPLOYMENT AGREEMENT

         This  Agreement,  dated as of October 23,  1996,  by and  between  AT&T
Corp.,  a New  York  Corporation  with  its  headquarters  at 32  Avenue  of the
Americas, New York, New York 10013 (hereinafter called the "Company"),  and John
R. Walter (hereinafter called the "Employee").

         WHEREAS the Employee was employed  as a senior
executive  with another
company; and

         WHEREAS the Employee has accepted employment with the
Company; and

         WHEREAS the Company has assigned and appointed the Employee to a Senior
Management  position as President  and Chief  Operating  Officer of the Company,
reporting to the Chairman, with the contemplation that after a transition period
he will  become  Chief  Executive  Officer  of the  Company  and  later be named
Chairman of the Board.  Employee has also been elected a member of the Company's
Board of Directors.

         WHEREAS,  it is of special  importance  for the Company to mitigate the
impact on Employee of early departure from the Employee's prior employer;

         NOW,  therefore,  and in  consideration  of the promises
and the mutual
agreements  as set forth  above  and  hereinafter  contained,
the  Company  and
Employee do hereby agree as follows:

         1.  Employment.  Subject to the provisions set forth  elsewhere in this
Agreement,  the Company  hereby  employs the Employee  and the  Employee  hereby
accepts  employment with the Company as President and Chief Operating Officer of
the Company during the employment  term set forth in Section 2 of this Agreement
with  the  contemplation  that at the time  periods  announced  by the  Company,
Employee will become Chairman and Chief Executive Officer.  The Company has also
elected  Employee  as a member of the  Company's  Board of  Directors.  Employee
represents  and warrants that there are no agreements or  arrangements,  whether
written or oral,  in effect  which would  prevent him from  rendering  exclusive
services to the  Company  during the term  hereof,  and that he has not made and
will  not make any  commitment,  agreement  or  arrangement,  or do any act,  in
conflict with this  Agreement and that entering into this  Agreement will not be
in violation of any other agreement. Such employment shall be upon the terms and
conditions hereinafter contained.

         2.  Term  of  Employment.   The  term  of  employment  hereunder  ("the
Employment  Term") shall commence on October 23, 1996 (the "Effective Date") and
will terminate at the will of either party to this Agreement upon written notice
to the other and shall be subject to the terms and conditions of the Agreement.

         3. Employee's Compensation and Benefits.  Subject to this Agreement and
as more fully set forth  hereinbelow,  during the Employment  Term, the Employee
shall be treated in the same  manner as, and be entitled  to such  benefits  and
other perquisites and terms and conditions of employment no less favorable than,
Senior  Managers  of  the  Company  at  a  similar  level  and  with  comparable
responsibilities.  Employee shall receive no additional compensation for serving
as a member  of the  Board of  Directors  of the  Company  or as an  officer  or
director of any subsidiary or affiliate.

                  (a) Base  Salary.  The Company  agrees to pay and the Employee
agrees to accept for  services to be rendered  hereunder  during the  Employment
Term, a base salary of not less than $975,000 a year, payable in installments on
a monthly or other  periodic  basis in accordance  with the  prevailing  payroll
practices of the Company.  Employee  will be eligible for  consideration  by the
Compensation  Committee  of base salary  increases as  appropriate  from time to
time.

<PAGE>

                  (b) Perquisites. During the Employment Term, the Company shall
(i) provide the Employee with perquisites of employment as are commonly provided
to  an  employee  of  the  Company  at  a  similar  level  and  with  comparable
responsibilities,  and (ii)  reimburse the Employee for reasonable and necessary
business expenses incurred in connection with his employment, in accordance with
employee business expense practices  applicable to employees of the Company at a
similar level and with comparable responsibilities.

                  (c)  Benefits.  Subject  to the terms and  provisions  of this
Agreement,  during the  Employment  Term,  the  Employee  shall be  entitled  to
coverage  under or  benefits  in  accordance  with  those  employee  and  Senior
Management  benefit  plans  and  programs  as are made  available,  or which may
subsequently  become  applicable,  to other  Senior  Managers  of the Company at
comparable  levels.  Employee  shall be  entitled  to five (5)  weeks of  annual
vacation applicable to 1997 and subsequent years, provided however, Employee may
commence  taking his 1997 vacation any time after the Effective  Date.  Employee
shall also be entitled to:

         -- Relocate under the terms of the AT&T  Management
Relocation Plan

         -- Utilize  the  assistance  of  one  or  more firms of
his choice for
            purposes of the Company's financial counseling program

         -- Receive  death  benefit  coverage at a rate of two
times base salary
            under the AT&T  Senior  Management  Basic  Life
Insurance  Plan,  a
            split-dollar life insurance program, or any successor
program.

         -- Commencing the month Employee closes on his New Jersey
residence, in
            lieu  of  any   Mortgage   Interest  or  High
Housing   Cost  Area
            Differentials under the AT&T Management Relocation
Plan, the Company
            will provide a temporary (i.e., 36 month) monthly
housing  allowance
            of $10,500  for each of the first 12  months,  8,400
for each of the
            next 12 months and $6,300 for each of the final 12
months.

                  (d) Incentive Plans.  During the Employment Term, the Employee
will be  eligible  for  consideration  for both long term and  annual  incentive
awards  pursuant to the terms of the Company's 1987 Long Term Incentive  Program
and  Short-Term   Incentive  Plan,   respectively  (the  "Incentive  Plans")  or
replacements thereof, as are in effect from time to time, at levels and on terms
and  conditions  consistent  with  awards  to  other  Senior  Managers.   Annual
incentives for AT&T Senior Managers  currently take the form of AT&T Performance
Awards  (APA) and Merit  Awards  (MA).  Award  levels  under the APA program are
predicated  on  overall  corporate  performance  and award  levels  under the MA
program are  determined by individual and team  contributions.  Employee will be
eligible for a prorated 1996 Annual  Incentive  based on his partial  service in
1996. The Company cannot make any representations  regarding the continuation of
the APA/MA incentive  format, or the size of Employee's APA and MA awards in any
given year,  if any.  Notwithstanding  the  foregoing,  Employee's  standard (or
target)  annual  incentive  opportunity  under such  Incentive  Plans,  or those
replacement  plans as may from  time-to-time be in effect,  for 1997 (payable in
1998) shall not be less than $1,170,000 and for 1998 and 1999 it is contemplated
such  target  annual  incentive  opportunities  shall  not be less  than 120% of
Employee's base salary as of the first day of such year.


<PAGE>

         As of the Effective Date, the Compensation Committee has awarded 34,175
Performance  Shares/Stock  Units to the Employee  under the Company's  1987 Long
Term Incentive Program covering the 1996 - 1998 performance  period,  subject to
the terms and conditions set forth in the Stock Unit Award Agreement provided to
Employee  with  this   Agreement.   Distributions   of  Long  Term   Performance
Shares/Stock  Units will be in  accordance  with the  applicable  1987 Long Term
Incentive Program and award provisions,  provided,  however, that as a result of
the Company's  restructuring and the difficulty of setting  long-term  financial
targets  while  the  restructure  is  in  progress,   the  performance  criteria
established  for the 1996 - 1998 long-term  cycle are not  applicable.  For such
performance  period,  the  criteria  are  deemed to have been met at the  target
level.  However, the opportunity to earn a payout above 100% is eliminated,  and
all other terms and conditions of the award continue to apply.  In January 1997,
Employee will also be eligible to receive a Performance  Share/Stock  Unit Award
for the 1997 - 1999  performance  period or a  replacement  long term  incentive
vehicle of generally  comparable value. The Compensation  Committee of the Board
has not yet determined the format or magnitude of such award.

         Also, as of the Effective Date of this Agreement,  a Stock Option Award
with  respect to 112,500  shares of AT&T  Common  Stock has been  granted to the
Employee  under the Company's 1987 Long Term  Incentive  Program.  Such Award is
subject to the terms and conditions set forth in the Non-statutory  Stock Option
Agreement provided to Employee with this Agreement.  The option price is 100% of
market price on the  Effective  Date.  In January  1997,  Employee  will also be
eligible to receive  another Stock Option grant,  the magnitude of which has not
yet been determined by the Compensation Committee.

         As with the Annual  Incentive  Award,  Long Term Incentives are closely
linked with the  Company's  strategy to meet the  challenges of an ever changing
marketplace.  Accordingly,  other than the grants as made in this Agreement, the
Company  cannot  guarantee  continuation  of the Long Term Incentive Plan in its
current  format,  nor  can  it  guarantee  annual  grant  levels  to  individual
participants.  Notwithstanding  the  foregoing,  to further  incent  Employee to
achieve  Company's goal of  substantially  enhancing  shareowner  wealth,  it is
contemplated  Employee  will receive (i) Stock Option  grants for Company  Stock
that will  average no less than  200,000  options per year  (adjusted  for stock
splits or other  occurrences  that result in  adjustments  of shares  subject to
outstanding  stock  options)  during  1997,  1998 and 1999  delivered  through a
variety  of grant  forms  e.g.,  standard  annual  grants,  special  grants  and
"premium"  grants  and  (ii)  awards  of  Performance   Shares/Stock   Units  or
replacement  long term equity  incentives that will have an average value at the
time of grant during  1997,  1998 and 1999 of at least  $1,350,000,  per year on
terms and conditions as the  Compensation  Committee shall determine at the time
of the  awards,  provided  that  such  terms  and  conditions  shall  be no less
favorable to Employee than for long term equity awards being simultaneously made
to other Senior Managers.

         The terms and  conditions  of various  long-term  incentive  awards set
forth in the attached Award Agreements and in this Agreement,  are in accordance
with the scope and provisions of the Company's 1987 Long-Term Incentive Program.

                  (e) Hiring Bonus. To recognize  certain
forfeitures  Employee
will  incur when he leaves his  current  employer  and to incent
him to join the
Company,  the  Compensation  Committee  has as of the  Effective
Date  of  this
Agreement granted the following one time special arrangements to
Employee:
<PAGE>

             --   An award of 34,175  "Seasoned"  1995 - 1997
AT&T  Performance
                  Shares/Stock Units (i.e., Performance
Shares/Stock Units which
                  would  have  been  granted  to  Employee  had he
been with the
                  Company in 1995) under the AT&T Long Term
Incentive  Program,
                  as set forth in the Stock Unit  Award
Agreement  provided  to
                  Employee  with  this  Agreement.  As  a  result
of  Company's
                  restructuring   and  the   difficulty  of
setting   long-term
                  financial  targets while the  restructure is in
progress,  the
                  performance criteria established for the 1995 -
1997 cycle are
                  not applicable and for this performance
period,  the criteria
                  are deemed to have been met at the target
level.  However, the
                  opportunity to earn a payout above 100% is
eliminated, and all
                  other terms and conditions of the award continue
to apply.

             --   A  $5,000,000  cash  bonus  payable  within
ten  days  of the
                  Effective  Date.  Employee has expressed a
desire that he will
                  use a  substantial  portion of the  after-tax
proceeds of the
                  bonus to  purchase,  with the  intent to retain
for long term
                  investment purposes, 50,000 shares of AT&T
Common Stock.

             --   A stock  option  award on the  Effective  Date
with respect to
                  112,500 shares of AT&T Common Stock,  subject to
the terms and
                  conditions  set  forth  in  the  Non-statutory
Stock  Option
                  Agreement  provided to  Employee  with this
Agreement,  which
                  terms  include,  but are not  limited  to, an
option  exercise
                  price equal to the market price per share of
AT&T Common Stock
                  on the Effective Date.

             --   An award of 75,000 AT&T Restricted Stock Units,
subject to the
                  terms  and  conditions  set  forth  in the
Stock  Unit  Award
                  Agreement provided to Employee with this Agreement.

             --   Two "premium"  stock option awards on the
Effective Date, each
                  with respect to 100,000  shares of AT&T Common
Stock,  subject
                  to the terms  and  conditions  set forth in the
Non-statutory
                  Stock  Option  Agreements   provided  to
Employee  with  this
                  Agreement,  which  terms  include,  but are not
limited to, an
                  option  exercise  price equal to the market
price per share of
                  AT&T Common Stock on the Effective Date.

             --   Establishment  of a Deferred Account to be
maintained and paid
                  to Employee in accordance  with the following
provisions:  On
                  the  Effective  Date,  the Company  shall
credit the Deferred
                  Account with an initial  balance of
$7,000,000.  The Deferred
                  Account will be  maintained  as a  bookkeeping
account on the
                  records of the Company and the Employee will
have no ownership
                  interest  in the  Deferred  Account,  nor in
any  asset of the
                  Company with respect thereto.  The Deferred
Account may not be
                  assigned,  pledged or otherwise  alienated by
the Employee 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.  Employee  shall not have any right
to receive any
                  payment  with  respect  to the  Deferred
Account,  except  as
                  expressly provided below. The Company shall
credit interest to
                  the Deferred  Account as of the end of each
calendar  quarter
                  (and  compounded  quarterly) at a rate equal to
one quarter of
                  120% of the Applicable  Annual Federal Mid-Term
Rate in effect
                  for the last month of such quarter. The vesting,
forfeiture or
                  distribution  of the Deferred  Account  shall be
in accordance
                         with the following provisions:

                  In the event of termination of Employee's
employment prior to
                  the fifth anniversary of the Effective Date:
<PAGE>
                  --     For any reason other than death, "Long
Term Disability"
                         (as defined below),  Company-initiated
termination for
                         other than  "Cause" (as defined  below),
or  Employee-
                         initiated  termination  for "Good
Reason"  (as defined
                         below),  then all amounts in the Deferred
Account shall
                         be  cancelled  and  Employee   shall
not  receive  any
                         distribution with respect to the
Deferred  Account;  or
                         have any further interest in the Deferred
Account

                  --     By reason of death or Long-Term
Disability, all amounts
                         credited  through  the last day of the
first  calendar
                         quarter  of the  calendar  year
following  the year in
                         which such  termination  of employment
occurs shall be
                         paid to Employee  (or,  in the event of
the  Employee's
                         death to Employee's beneficiary
designated on a Company
                         form filed with Executive  Human
Resources,  or to his
                         estate if no beneficiary has been
designated),  within
                         30 business days of the end of such
calendar  quarter;
                         or

                  --     By reason of  Company-initiated
termination  for other
                         than Cause, or Employee-initiated
termination for Good
                         Reason,  amounts credited to the Deferred
Account shall
                         continue  to accrue  interest  through
the later of (i)
                         the last day of the calendar quarter in
which the fifth
                         anniversary of this  Agreement  occurs or
(ii) the last
                         day of the first calendar  quarter of the
calendar year
                         following the year in which such
termination occurs, at
                         which time the balance credited to the
Deferred Account
                         shall  be  paid  to the  Employee  (or
his  designated
                         beneficiary or estate, as described
above, in the event
                         of his death)  within 30 business days
after the end of
                                  such quarter;

         In the event of  termination of Employee's  employment  after the fifth
anniversary  of the Effective Date for any reason,  all amounts  credited to the
Deferred  Account  through  the last day of the first  calendar  quarter  of the
calendar year following the year in which such termination of employment  occurs
shall be paid to the  Employee (or his  designated  beneficiary,  or estate,  as
described  above,  in the event of his death)  within 30 business days after the
end of such quarter.

         Payments  from the Deferred  Account are in addition to and not in lieu
of any pension,  savings, or other defined benefit or defined contribution plan,
program or arrangement  covering  Employee,  including other  provisions of this
Agreement.  The Company shall pay to Employee an additional amount which,  after
gross-up for applicable Federal and state income,  payroll and other withholding
taxes in  accordance  with the  Company's  tax gross-up  policies  applicable to
Senior  Management,  is equal  to the FICA  Medicare  tax  withholding  due from
Employee on the initial $7,000,000  deferral (but not earnings thereon) upon the
establishment of the Deferred Account or, if not then so taxable, when such FICA
Medicare tax becomes due.

         For purposes of this Agreement:

         "Long Term Disability" shall mean termination of Employee's  employment
with the Company with  eligibility to receive a disability  allowance  under the
AT&T Senior  Management Long Term  Disability and Survivor  Protection Plan or a
replacement plan.


<PAGE>

         "Good  Reason"  shall mean a material  breach of this  Agreement by the
Company  which is not cured within  twenty days of the giving of written  notice
thereof by  Employee.  Good reason  shall  include  any  uncured  failure by the
Company to provide the compensation and benefits required hereunder,  to provide
the contemplated  equity and incentive awards as stated hereunder  (except those
that cannot  legally be  continued)  or awards that the  Compensation  Committee
believes  in good faith  provide  substantially,  in the  aggregate,  equivalent
pre-tax  economic  benefits and  opportunities  to the  foregoing,  to elect the
Employee to the future offices  contemplated  by this Agreement  within the time
framework announced by the Company,  to maintain Employee in such positions,  or
to effect an assumption as provided in Section 10(b). Employee's sole remedy for
any breach of this  Agreement by the Company  during the  Employment  Term which
would provide him with a right to terminate with Good Reason,  including but not
limited to failures  referred to in the prior  sentence,  shall be a termination
for Good  Reason and the  amounts  and  benefits  provided  hereunder  upon such
termination (as well as any accrued but unpaid base salary, accrued vacation and
amounts due under the terms of any plan or program upon such  termination),  and
in no event shall the Company or its  affiliates be liable for any other damages
of any kind  whatsoever  as a result of any such  breach.  The amounts  paid and
benefits provided upon such a Good Reason termination shall be deemed to include
liquidated  damages for such breach,  and Employee  shall not be entitled to any
actual damages (which the parties agree would be difficult,  if not  impossible,
to determine).  Any notice of termination of employment for Good Reason shall be
given  within  180 days  after the  occurrence  of the event on which  such Good
Reason termination is to be based.

         For  purposes of this  Agreement,  any award  agreement,  and any other
agreement,  plan or program of the  Company to which  Employee  is a party or by
which he is covered, "Cause" or "cause" (or words of similar import) shall mean:

         (i)      The Employee  is convicted (including a plea of
guilty or nolo
                  contendere) of  a  felony involving  theft or
moral turpitude,
                  other  than  a  felony  predicated  on
Employee's  vicarious
                  liability.  Vicarious  liability  means, and
only  means, any
                  liability which is based on acts of the  Company
for which the
                  Employee  is  charged solely  as a result of
his  offices with
                  the  Company and in which he was not directly
involved  or did
                  not  have prior knowledge of such actions or
intended actions.

         (ii)     The Employee engages in conduct that constitutes
willful gross
                  neglect or willful gross misconduct in carrying
out his duties
                  under this Agreement,  resulting,  in either
case, in material
                          economic harm to the Company.

         4.  Special Pension and Other Post-Termination
Arrangements.

                  (a) In the event Employee's  employment terminates on or after
Employee's  55th  birthday  for any reason  other  than for a  Company-initiated
termination  for Cause,  the Company will provide an immediate  pension  benefit
(the  "Special  Pension")  based  on (1)  the  greater  of the  pension  amounts
reflected  in  Attachment  A or (2) actual  Company  Net  Credited  Service  and
compensation   calculated  under  the   then-existing   Company   qualified  and
non-qualified  pension  formulas,  but  without  reference  to age  and  service
eligibility  requirements  for  purposes of  determining  benefit  commencement,
(i.e.,  such accrued  pension  benefits would normally under plan  provisions be
payable at age 65, therefore waiving the age and service eligibility requirement
will facilitate payment of such accrued benefits commencing as early as age 55).
Non-qualified  pensions affected by these practices would include those provided
under the AT&T Non-Qualified Pension Plan, the AT&T Mid-Career Pension Plan, but
specifically  would exclude the minimum  retirement benefit and surviving spouse
benefit  payable  under the AT&T  Senior  Management  Long-Term  Disability  and
Survivor Protection Plan. Special Pension payments shall be paid to the Employee
from Company  operating  income and Employee shall be a general  creditor of the
Company with regard to such benefits. Such benefits may not be assigned, pledged
or  otherwise  alienated  by the  Employee  and  any  attempt  to do so,  or any
garnishment, execution or levy of any kind with respect to the Special Pension,

<PAGE>

will not be recognized.  The total pension amount which results from application
of the preceding provisions of this Section 4 will be reduced by (1) the pension
payable by Employee's  former employer and (2) all amounts actually  received by
Employee  or his  surviving  spouse  under  any  other  Company  or  affiliate's
qualified or non-qualified  pension,  retirement,  disability or annuity plan or
program, except the AT&T Long-Term Savings Plan for Management Employees and the
AT&T Senior Management  Incentive Award Deferral Plan.  Special Pension benefits
payable under this Section 4 will be afforded the same post  employment "ad hoc"
inflation  adjustments,  if any, as may be applicable to the AT&T  Non-Qualified
Pension Plan from time to time.

                  Employee may elect,  prior to the  commencement of the Special
Pension (or, if earlier,  such earlier date such that the election  would not be
subject to constructive receipt treatment) to receive the benefit in the form of
a joint and 50% survivor  annuity  with his spouse (or under any other  optional
form of  benefit  then  available  under  the AT&T  Management  Pension  Plan or
replacement  plan) at the time of such election,  subject to the  adjustments as
provided  for in  Attachment  A. To the  extent any  adjustments  in form of any
benefit are required to calculate an offset, the actuarial practices  applicable
to the AT&T  Management  Pension  Plan or  replacement  plan shall be used.  Any
benefits with a later starting date than this Special  Pension  benefit shall be
offset only when such offsetting benefits commence.  In the event termination is
as a result of the  Employee's  death,  a 50% survivor  annuity shall be paid to
Employee's spouse, if any, assuming,  for benefit calculation  purposes,  he had
terminated his employment and commenced  benefits in the form of a joint and 50%
survivor annuity on the day before his death.

                  (b)  Conditioned   upon  termination  and  eligibility  to  an
immediate pension under Section 4(a), Employee will be entitled to the following
post-termination  ancillary  entitlements,  administered in a manner  consistent
with the then-current  treatment of Service Pension eligible Senior Managers and
in accordance with the terms and conditions applicable to each Senior Management
plan, program or practice (or replacement  therefor) as they may exist from time
to time.

         --       Two times base salary Senior Management Basic
Life Insurance

         --       One and  one half  times  salary  Senior

         --       One times salary plus annual  incentive death
benefit normally
                  payable  under  the  AT&T  Management  Pension
Plan  and AT&T
                  Non-Qualified  Pension  Plan to certain
qualified  survivors,
                  e.g., spouse or dependent child of a Service
Pensioner. In the
                  event:  (1) such benefit is  available  to
Service  Pensioners
                  upon  Employee's  death and (2)  Employee is
not  eligible for
                  such benefit,  then in such case a death benefit
equal to such
                  benefit will be paid from the Company's
operating income to a
                  qualified  survivor,  if any,  per  comparable
death  benefit
                  provisions  under the AT&T  Management  Pension
Plan. Any lump
                  sum death  benefit  payable  under the AT&T
Senior  Management
                  Long Term  Disability and Survivor  Protection
Plan will be an
                  offset to the death benefit payable under this
provision.

         --       Participation in the post-retirement Senior
Management benefit
                  or prerequisite  plans,  programs and practices

                  employee  benefit  plan,  (except  those for
which  alternate
                  coverage  is made  available  in the  Agreement
or  through a
                  special Senior Management plan, program or
practice), but only
                  to the  extent and under  such  terms and
conditions  as such
                  employee   benefits   and  Senior   Management
benefits  and
                  perquisites are available to Service  Pension
eligible Senior
                  Managers at the time of Employee's termination.

         5. Powers and Duties.  The Employee shall devote his full business time
and  best  efforts  and  abilities  to the  performance  of  duties  under  this
Agreement,  it being  understood  in  connection  therewith  that he may, in his
discretion and subject to not interfering  with his duties and  responsibilities
hereunder,  devote time to civic,  public and  professional  activities  and may
serve as a director of other  business  corporations  not engaged in competition
with the  Company or any  subsidiary  or  affiliate  of the  Company;  provided,
however,  that he shall not accept  directorships  on more than three  boards of
other business  corporations;  and provided,  further,  that for purposes of the
immediately  preceding  clause,  directorships  on the  boards  of  two or  more
companies with at least 50% common  ownership  shall count as a single  company.
Furthermore,  so long as it does not  interfere  with  his  Company  duties  and
subject to the AT&T Non-Competition  Guideline,  Employee may continue to manage
his passive investments.

         6.  Indemnification.  The  Company  and  Employee  shall
promptly enter
into the Indemnity Agreement annexed hereto as Attachment B.

         7.  Restrictive Convenants.

                  (a) Competition.  Notwithstanding any other provisions 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
Employee 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 the Employee
at any time without the consent of the Company  "establishes a relationship with
a competitor"  or "engages in an activity"  which is in conflict with or adverse
to the  interest of the Company,  all within the meaning of the  Non-Competition
Guidelines referred to below (a "Competitive Activity"). The payments,  benefits
and other entitlements  hereunder are being made in part in consideration of the
obligations  of this Section 7 and in particular the  post-employment  payments,
benefits  and  other  entitlements  are  being  made in  consideration  of,  and
dependent  upon,  compliance with this Section 7(a) and, to the extent set forth
in Section 8, the Release and Agreement  referred to in Section 8.  Attachment C
is a copy of the Non-Competition Guideline.


<PAGE>

                  (b) Confidentiality.  The Employee agrees that he will not, at
any time  during  his  employment  pursuant  to this  Agreement  or  thereafter,
disclose or use any trade secret, proprietary or confidential information of the
Company or any  subsidiary  or  affiliate of the  Company,  obtained  during the
course of his employment, except as required in the course of such employment or
with the written permission of the Company or, as applicable,  any subsidiary or
affiliate  of the  Company  or as may be  required  by law,  provided  that,  if
Employee  receives legal process with regard to disclosure of such  information,
he shall promptly notify the Company and cooperate with the Company in seeking a
protective order.

         The  Employee  agrees  that  at  the  time  of the  termination  of his
employment  with the  Company,  whether at the  instance of the  Employee or the
Company,  and  regardless  of the  reasons  therefore,  he will  deliver  to the
Company,  and not keep or deliver  to anyone  else,  any and all  notes,  files,
memoranda,  papers and,  in  general,  any and all  physical  matter  containing
information,  including any and all documents  significant to the conduct of the
business of the Company or any  subsidiary or affiliate of the Company which are
in his  possession,  except  for any  documents  for  which the  Company  or any
subsidiary or affiliate of the Company has given  written  consent to removal at
the  time of the  termination  of the  Employee's  employment  and his  personal
rolodex, phone book and similar items.

         Employee agrees that the Company's  remedies at law would be inadequate
in  the  event  of  a  breach  or  threatened  breach  of  this  Paragraph  (b);
accordingly, the Company shall be entitled, in addition to its rights at law, to
an injunction and other equitable relief without the need to post a bond.

                  (c) Any Competitive  Activity by the Employee not permitted by
the  provisions  of Section 7(a) above shall  result,  at the  discretion of the
Company,  in the  cancellation  of all rights and  entitlements  of the Employee
hereunder  (including  but not  limited  to those  for  payments  or  benefits),
provided  that:  (i) the Deferred  Account in such event shall not be forfeited,
but  may at the  Company's  discretion  be  immediately  paid  out  and  (ii) no
forfeiture or cancellation (or accelerated payout of the Deferred Account) shall
take place 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 the Employee  written notice of its intent to so forfeit,  or cancel
or pay out and Employee has not,  within thirty (30) days of giving such notice,
ceased such unpermitted Competitive Activity,  provided that the foregoing prior
notice  procedure  shall  not be  required  with  respect  to (x) a  Competitive
Activity which Employee initiated after the Company had informed the Employee in
writing that it believed such Competitive  Activity violated Section 7(a) or the
AT&T Non-Competition  Guidelines,  (y) any Competitive Activity regarding local,
regional or long distance telephone services or other products or services which
are part of a line of  business  which  represents  more than 5%  percent of the
Company's  consolidated gross revenues for its most recent completed fiscal year
at the time the Competitive Activity commences.

         8.  Termination Provision.

                  (a) If,  at any time  during  the  period  beginning  with the
Effective  Date and  ending on the day prior to the  Employee's  55th  birthday,
Employee is  terminated  by the Company for any reason  other than Cause or Long
Term Disability or Employee  terminates his Company  employment for Good Reason,
the Employee will be entitled to:

         --    Monthly  payments  for a 12 month period
following  termination,
               each  such  payment  in an  amount  equal to one

               greater of (1)  $3,217,500  or (2) 150% of the sum
of  Employee's
               annual  base salary rate plus  target  Annual
Incentive  rate in
               effect as of the date of Employee's termination.


<PAGE>

         --    An annual incentive award for the year of
termination  payable at

and  payable  to
               Employee   within   fifteen   (15)   business

               termination.

         --    Distribution  of  the   Deferred  Account  as
provided  for  in
               Section 3(e).

         --    The  Special  Pension  provided  for  in  Section
4(a)  of  this
               Agreement   determined  on  the  basis  that
Employee's  age  at
               termination  was the greater of age 55 or his
actual age plus two
               years,  and further  provided  that such pension
will commence no
               earlier than his actual attainment of age 55.

         --    The  post-termination  benefits  and entitlements
as described in
               Section 4(b)

                  (b) If,  at any time  during  the  period  beginning  with the
Effective  Date of this  Agreement and ending on the day prior to the Employee's
55th birthday, Employee's employment terminates because of Long
Term Disability, the Employee will be entitled to:

         --    Distribution  of  the Deferred Account as provided
for in Section
               3(e)

         --    The  Special  Pension  provided  for  in  Section
4(a)  of  this
               Agreement assuming  Employee's age at termination
was the greater
               of age 55 or his actual age plus two years,  and
further provided
               that such pension will commence no earlier than his
actual
                  attainment of age 55.

         --    The  post-termination   benefits  entitlements  as
described  in
               Section 4(b)

         --    Employee's  surviving  spouse  shall be  entitled
to a  survivor
               pension  for her  lifetime  commencing  the month
after the month
               which includes the date of Employee's  death.  The
amount of such
               pension shall be $29,000 per month. This survivor
pension will be
               offset by the minimum  surviving  spouse pension
benefit (or lump
               sum alternate if such becomes  available)  payable
under the AT&T

                        payable to the surviving spouse.

         --    In addition,  amounts and  benefits  shall be paid
or provided as
               otherwise  specified  herein  or as  provided  in
the  applicable
               Company programs and plans upon an in-service death.

                  (d) In the event Employee's employment terminates  voluntarily
(other than for Good Reason) or as the result of a Company-initiated termination
for Cause,  at any time during the period  beginning with the Effective Date and
ending on the day prior to the  Employee's  55th  birthday,  Employee shall only
receive such amounts and benefits as are provided  under the Company's  programs
and plans.


<PAGE>

                  (e) Any payments or benefits  made  pursuant to this Section 8
are: (1) subject to the provisions, restrictions and limitations of Section 7(a)
and (c) above, but not otherwise subject to offset or mitigation, (2) subject to
Employee  signing a Release and  Agreement not to sue the Company in the form of
Attachment  D hereto with such changes  therein or  additions  thereto as needed
under  then  applicable  law to give  effect to the  intent of the  Release  and
Agreement  and  (3)  receipt  of  Employee's   resignation   from  all  offices,
directorships and fiduciary positions with the Company, its affiliates and their
respective benefit plans.  Notwithstanding  the due date of any  post-employment
payment,  any amounts due under this  Section 8 shall not be due until after the
end  of any  applicable  revocation  period  with  regard  to  the  Release  and
Agreement.

         9.  Dispute  Resolution.  At the option of the Employee or the Company,
any dispute,  controversy, or question arising under, out of or relating to this
Agreement or the breach  thereof,  other than that for  injunctive  relief under
Section 7(b),  shall be referred for decision by arbitration in the State of New
Jersey by a neutral  arbitrator  selected by the parties hereto.  The proceeding
shall be governed by the 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). If the parties are unable to agree upon such a neutral arbitrator
within thirty (30) days after either 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 an appointment of a neutral  arbitrator,  or if such Association is not then
in existence or does not act in the matter within 30 days of application, either
party may apply to the  Presiding  Judge of the Superior  Court of any county in
New Jersey for an  appointment  of a neutral  arbitrator to hear the parties and
settle the dispute, controversy or question, and such Judge is hereby authorized
to make such appointment.  In the event that either party exercises the right to
submit a dispute arising  hereunder to arbitration,  the decision of the neutral
arbitrator shall be final,  conclusive and binding on all interested persons and
no action at law or  equity  shall be  instituted  or,  if  instituted,  further
prosecuted  by either  party  other  than to  enforce  the award of the  neutral
arbitrator. The award of the neutral arbitrator may be entered in any court that
has  jurisdiction.  In the event that the Employee is successful in pursuing any
claim or dispute arising out of this Agreement,  the Company shall reimburse all
of the Employee's  attorney's  fees and costs,  including the  compensation  and
expenses of any arbitrator,  relating solely,  or allocable,  to such successful
claim. In any other case, the Employee and the Company shall each bear all their
own costs and  attorneys  fees,  except the  Company  shall pay the costs of any
arbitrator appointed hereunder.

         10.  Assignment.

                  (a) Employee.  This  Agreement is a personal  contract and the
rights and  interests of the Employee  hereunder  may not be sold,  transferred,
assigned, pledged or hypothecated by him, but shall be binding upon and inure to
the benefit of his heirs, administrators, and executors..

                  (b) Company.  This Agreement shall inure to the benefit of and
be binding upon the Company,  its  successors  and  assigns,  provided  that the
Company may not assign this Agreement except in connection with an assignment of
all or substantially all of the assets of the Company or by law as a result of a
merger or  consolidation.  In the  event of such  assignment,  a failure  by the
successor to  specifically  assume in writing,  delivered to the  Employee,  the
obligations and liabilities of the Company  hereunder shall be deemed a material
breach of this Agreement.

         11.  Taxes.  It is  understood  that all payments and
benefits provided
under this  Agreement are  subject to  withholding for applicable
federal, state
and local income (or similar) taxes.


<PAGE>

         12. Other. The Company reserves the right to prospectively  discontinue
or modify its compensation,  incentive,  benefit and perquisite plans,  programs
and practices,  but any such  discontinuance or modification  shall not diminish
any specified right of Employee  hereunder.  Moreover,  the very brief summaries
contained herein are subject to the terms of such plans, programs and practices.
For purposes of the employee benefit plans, the definition of compensation is as
stated in the plans.  Currently,  pensions  are based on base  salary and annual
incentives.  Other  benefits are based on either base salary or base salary plus
annual  incentives.  All  other  compensation  and  payments  included  in  this
Agreement are not included in the base for calculation of employee benefits. The
amounts paid under this  Agreement  upon a termination of employment are in lieu
of and  inclusive  of any  amounts  payable  under any other  plan,  program  or
practice of the Company with regard to termination of employment.

         13. Entire Agreement; Amendments. This Agreement, which may be executed
in two or more  counterparts,  comprises 23 pages, 16 Sections and 4 Attachments
and represents the entire Agreement  between Employee and the Company in respect
of the subject matter  contained  herein and  supersedes  all prior  agreements,

Management's Discussion and Analysis

     1996 was a historic year for AT&T as we  successfully separated into three
independent entities.

     In 1996 we successfully  completed our plan to separate into three publicly
held  stand-alone  companies,  each focused on serving certain core  businesses.
This  began  with  the  initial  public   offering  (IPO)  of  17.6%  of  Lucent
Technologies Inc. (Lucent) shares in April 1996, the largest IPO in history.  We
distributed to our shareowners all of the shares we owned of Lucent on September
30, 1996. On October 1, 1996, we completed the sale of our majority  interest in
AT&T Capital  Corporation  (AT&T  Capital) and we received $1.8 billion in cash.
Finally,  on December 31, 1996 we completed our plan when we  distributed to our
shareowners all of our shares in NCR Corporation (NCR).

     The actions taken in 1996 leave us in a strong position for the future. Our
debt ratio,  excluding financial  services,  at the end of 1996 was 18.7%, among
the  lowest in our  industry.  Our  return on  average  assets  from  continuing
operations was approximately 10.3%, among the highest in our industry.

     We made  significant  expenditures in 1996 for strategic  investments  into
various  markets which we believe  complement our core  business.  These include
internet  access,  consulting and  outsourcing and local  expansion.  In 1996 we
continued our market share leadership in the consumer and business long distance
markets.

     We continued to provide new products and services to our customers, such as
our  AT&T  One  Rate  program,  a flat  15-cents-a-minute  plan  for  consumers.
Announced  at the end of  September,  the  program  already had nearly 3 million
subscribers at the end of December.  Although the majority of One Rate customers
are  existing  AT&T  customers  moving from other  calling  plans,  One Rate has
attracted a number of wins from competitors.  Success in the  telecommunications
market is about  meeting  complex  customer  needs and  providing  valuable  and
reliable  services.  We are  committed to meeting  these needs by providing  the
necessary  service plans and by maintaining the AT&T long distance network which
has unparalleled reliability by almost any measure.

     We continued to expand our  relationship  with our business  customers from
one of simply carrying voice and data traffic playing a consultative role and

<PAGE>

becoming strategic partners. We now provide business consulting, outsourcing and
electronic  commerce  solutions  among other services to business  markets.  For
example,  we signed a $1.1 billion,  ten-year  contract  with  Textron,  Inc. to
upgrade, expand and manage their global communications infrastructure.

     As a result of the strategic  restructuring,  some changes in our financial
reporting format have been made. In order to  appropriately  reflect the ongoing
operations  of the  "new"  AT&T,  certain  reclassifications  have  been made to
reflect  the  results of  businesses  that we have  divested  or plan to divest.
Accordingly, the revenues and expenses, assets and liabilities and cash flows of
Lucent,  NCR and AT&T Capital,  as well as certain other  businesses,  have been
excluded from the respective captions in the Consolidated  Statements of Income,
Consolidated  Balance Sheets and Consolidated  Statements of Cash Flows. The net
operating  results of these businesses have been reported as "Income (loss) from
discontinued operations," net of applicable income taxes, the net assets as "Net
assets of  discontinued  operations" and the net cash flows as "Net cash used in
discontinued  operations." In addition,  the consolidated results for continuing
operations   have  been   reclassified   to  improve   comparability   with  the
communications services industry. As a result of the spin-offs of Lucent and NCR
and the sale of AT&T  Capital,  our  Consolidated  Balance Sheet at December 31,
1996  no  longer   includes  these  entities  in  "Net  assets  of  discontinued
operations."  Additionally,  the  results of  operations  and net cash flows for
Lucent and AT&T Capital are reflected in our  Consolidated  Statements of Income
and  Consolidated  Statements of Cash Flows through the date these  dispositions
occurred.

Restructuring and Other Charges

     In the fourth quarter of 1995 we recorded a pretax charge of $3,029 million
for  restructuring  costs of  $2,307  million  and asset  impairments  and other
charges of $722 million.  The charges  covered  consolidating  and  reorganizing
numerous  corporate and business unit operations  over several years.  The total
pretax  charge was recorded as $844 million in network and other  communications
services,  $934 million in  depreciation  and  amortization,  $1,245  million in
selling,  general  and  administrative  and $6  million  in  financial  services
expenses. The tax benefit associated with the charges was $993 million.

     During 1996 we continued to implement our restructuring plans. We completed
the restructuring of our proprietary  network and messaging  services  business,
closed several call servicing centers,  sold certain  international  operations,
and reorganized and reduced certain corporate support functions.  As of December
31,  1996,  approximately  5,000  management  employees  and 1,000  occupational
employees   have  been   separated.   Of  the  5,000   management   separations,
approximately 3,000 accepted voluntary separation packages. We expect the

<PAGE>

majority of our plans to be completed during 1997.  However,  certain  severance
and  facility  costs  have  payment  terms  extending  beyond  1997.  A detailed
discussion of  restructuring  and other charges is in Note 5 to the Consolidated
Financial Statements.

     AT&T operates in two industry segments, the telecommunications industry and
the financial services industry.  Our communications  services (which is part of
the telecommunications industry) consists of a wide range of services to
residential  and  business  customers,   including  domestic  and  international
wireline  long  distance  voice,  data and video  services,  wireless  services,
network  management,  business  consulting,   outsourcing,  electronic  commerce
solutions and internet access service.  Our financial services segment primarily
consists of our AT&T Universal Card credit card business.

COMMUNICATIONS SERVICES

     Communications services revenues grew 4.4% in 1996 and 5.4% in 1995.

Operating margin                         17.3%         10.7%          16.0%

     Wireline  services revenue,  which includes  traditional long distance toll
calling,  network  management,  messaging  and other  network-enabled  services,
increased 3.2% in 1996 and 4.5% in 1995. We handled a record 68 billion calls in
1996, causing  conversation minutes for switched long distance services (volume)
to rise 5.9%.  The volume  growth in 1996  slowed  from the nearly  9.0%  growth
registered in 1995, reflecting competitive pressures from traditional sources in
the  consumer  markets  as  well  as  nontraditional  sources  such  as  smaller
telecommunications  companies  and  dial-around  resellers.  This  pressure  was
somewhat  offset  by  strong  volume  growth  in  business   inbound   services,
particularly toll-free 800 and 888 services.

     Volume growth  continued to exceed revenue  growth in 1996.  This reflected
lower pricing from  promotional  discounts,  increased  movement of customers to
optimal calling plans and increased  discounts  given to large  accounts.  As we
continued  to expand  internationally,  international  volumes  increased  while
related revenue remained relatively flat.

<PAGE>

     In 1995 we saw volume growth in calling card, business inbound services and
consumer international services.  Although volume growth exceeded revenue growth
(due  primarily  to  customers   taking  advantage  of  our  calling  plans  and
promotions),  the gap between  revenues  and volumes was about 4% in 1995.  This
reflected  movement  among  calling  plans  by  both  business  and  residential
customers and some targeted price increases.

     The long  distance  market  is  increasingly  characterized  by  aggressive
pricing  actions,  the  introduction  of new  competitors  (such as  dial-around
resellers) and price sensitivity on the part of consumers.  As a result, revenue
as well as volume growth was adversely impacted. We expect that these conditions
will  intensify in the future as the Regional Bell Operating  Companies  (RBOCs)
are permitted to provide long distance  services in their home regions,  thereby
negatively  impacting our long distance  volume and revenue.  As the RBOCs,  who
currently have zero market share,  begin  providing long distance  services,  we
will lose long distance market share.  However, we will gain market share in the
local telephone service market as we are able to enter it.

     Wireless services revenue, which includes cellular, messaging services, and
air-to-ground services, grew 18.8% in 1996 and 28.3% in 1995. The growth in both
periods was the result of consolidated  cellular  subscriber  growth of 31.7% in
1996 and 39.2% in 1995.

     Cellular  customers,  reported on the same basis as  consolidated  wireless
revenues, stood at 5.2 million at December 31, 1996 compared with 3.9 million at
December  31, 1995 and 2.8  million at December  31,  1994.  Cellular  customers
served by companies in which we have or share a controlling  interest  increased
to 7.1  million at December  31, 1996 from 5.5 million at December  31, 1995 and
4.0  million  at  December  31,  1994.   Cellular  revenue  per  subscriber  was
approximately $60 per month in 1996 compared with  approximately $69 in 1995 and
approximately  $79  in  1994.  The  decline  reflected   industry  wide  pricing
pressures,  as well as lower average usage per subscriber as expansion  included
growth in  subscribers  who are more casual users (e.g.  for emergency and other
personal  use).  However,  based on reported  financial  information of wireless
competitors,  our revenue per  subscriber  is above the  industry  average.  The
number of casual  users is  expected  to  continue  to grow in 1997,  which will
likely result in lower average revenue per subscriber next year.

     By combining  our 800 MHZ  cellular  and 1900 MHZ  personal  communications
services (PCS) licenses,  we can eventually  provide wireless  telecommunication
services  to  markets  covering  approximately  93% of the U.S.  population.  In
October  1996 we  launched  AT&T  Digital  PCS  service  in more  than 40 of our
existing 800 MHZ wireless markets,  covering 70 million potential customers. The
difference  between  AT&T  Digital  PCS and  analog  cellular  service is in the
features.  AT&T Digital PCS provides  longer battery life,  short text messaging
service, caller identification, message waiting indicator and enhanced security.

<PAGE>

     AT&T  Digital  PCS  allows  customers  to make and  receive  voice and data
transmissions  to people  rather than places.  At December 31, 1996, we had more
than 900,000 digital subscribers,  including over 500,000 receiving AT&T Digital
PCS service.

     The overall  penetration rate (number of cellular customers as a percentage
of the total  population in the service  territory) for markets in which we have
or share a controlling interest increased from 5.9% at December 31, 1995 to 7.5%
at December 31, 1996.

     Products and other services revenue includes wireless product sales, online
services,  consulting and outsourcing services,  and other sales and services to
businesses and consumers. Products and other services revenue increased 11.2% in
1996 and decreased 6.5% in 1995. The roll-out of new and nontraditional services
drove the  increase  in 1996.  The 1995  decrease  was mainly due to lower other
services in our wireless business.

     During  1996  we  began  offering   internet   access  service  under  AT&T
WorldNet(sm)  and had  568,000  subscribers  by the end of the  year.  Our  AT&T
WorldNet(sm) and hosting services and our consulting and outsourcing  businesses
contributed  to the increase in revenues.  However,  these  start-up  businesses
required significant expenditures in both years. These investments are necessary
for us to expand  into the  strategic  areas we  believe  are  important  to our
future.

     We signed numerous agreements in 1996 to provide consulting and outsourcing
services to various  companies.  We expect these agreements to increase products
and other services revenue in 1997. Revenue expected under contracts executed in
1996  primarily  for  outsourcing  amounted  to  approximately  $2.9  billion at
December 31, 1996. This is earned over the contract term, which can extend to up
to 10 years.  Since  revenue  depends on actual usage under  service  contracts,
actual  revenue  for a  particular  contract  may be  higher  or lower  than the
reported expected amount.

Operating Expenses

     Operating expenses for  communications  services included $3,023 million of
restructuring  and other  charges  in 1995 and $246  million  of McCaw  Cellular
Communications,  Inc. (McCaw)  merger-related  expenses in 1994. Excluding these
charges,  operating expenses for communications  services increased 3.9% in 1996
and 5.0% in 1995.  The 1996  growth was due to  increased  selling,  general and
administrative  expenses and increased network and other communications services
expenses  partially  offset  by  decreased  access  and  other   interconnection
expenses.  The 1995 growth was primarily due to increased  selling,  general and
administrative expenses. The expense growth rate decreased in 1996 primarily due
to lower access and other  interconnection  charges.  As a result, the operating
margin  for  communications  services  increased  in 1996 to 17.3% from 16.9% in
1995, excluding restructuring and other charges, and 16.6% in 1994.

<PAGE>

     Access and other  interconnection  expenses are the charges for  facilities
provided by local  exchange  carriers and other domestic  service  providers and
fees paid to foreign telephone companies (international  settlements) to connect
calls  made to or from  foreign  countries  on our  behalf.  These  charges  are
designed to reimburse these carriers for the common and dedicated facilities and
switching equipment used to connect our network with their network.  These costs
declined in both 1996 and 1995 due to lower  per-minute  access  cost  resulting
from  changes  in  the  price  setting  methodology   approved  by  the  Federal
Communications  Commission (FCC), operational improvements in our infrastructure
and reduced international  settlements.  The decrease in 1996 was also partially
due to a second quarter accounting  adjustment of previously  estimated accruals
to reflect actual billing.  These  reductions were partially offset by increased
volumes and international traffic mix. Access and other interconnection expenses
as a percentage of wireline  services  revenue were 35.8% in 1996, 39.8% in 1995
and 42.1% in 1994.

     Network and other  communications  services  expenses include operating and
maintaining our network,  operator  services,  nonincome taxes and the provision
for  uncollectible  receivables.   Network  and  other  communications  services
expenses,  excluding  $844  million in 1995 related to  restructuring  and other
charges,  increased  in both  1996  and  1995 due to  increased  costs  from our
expansion into new  initiatives,  enhancements  made in customer care facilities
and higher provisions for uncollectibles.

     New initiatives such as AT&T WorldNet(sm) and hosting  services,  preparing
for  local  service  entry  and  our  consulting  and   outsourcing   businesses
represented   approximately   half  of  the   increase   in  network  and  other
communications  services  expenses in 1996 and most of the increase in 1995.  We
filed to offer  local  service in all 50 states  less than three weeks after the
Telecommunications  Act of 1996  (the  Telecommunications  Act)  was  signed  in
February  1996.  As of December 31, 1996,  we had received  authority to provide
local service in 42 states.

     The higher provision for uncollectibles in 1996 reflects  collection issues
as well as a shift in industry wide credit risk  profiles of business  customers
which resulted in increased bankruptcies, delinquencies and fraud. In particular
the business reseller market has experienced  significant  competition which has
had a  negative  impact  on  these  customers'  payment  patterns.  Our  ongoing
provision for uncollectibles  will continue to reflect the increased risk in our
business markets.

     In 1996  the  cost of  operating  our  worldwide  intelligent  network  was
essentially  unchanged  despite  increased  calling  volumes  and the  increased
complexity of our service offerings.

     Depreciation   and  amortization   expenses,   excluding  $934  million  of
restructuring and other charges in 1995, increased $154 million or 6.0% in 1996.
This increase was  primarily  the result of additions to the  telecommunications
network and was partially  offset by the impact of the asset  write-downs at the
end of 1995.  We expect  depreciation  and  amortization  expense to continue to
increase with the expansion of our networks.  (See Financial  Condition and Cash
Flows - Investing activities for a discussion of capital expenditures.)

     Additionally, subsequent to their divestment, purchases from Lucent and NCR
are recorded at the full commercial  price. When these entities were part of our
consolidated  results,  these  purchases were  reflected at their  manufacturing
costs.  Going  forward,  this will  result in higher  capital  expenditures  and
related  depreciation  expense as well as higher period expenses for those items
not capitalized. We have committed to purchase $3,000 million from Lucent by the
end of 1998 and $350 million from NCR by the end of 1999.  By the end of 1996 we
had purchased $2,726 million from Lucent and NCR under these agreements.

     In 1995  depreciation and amortization  expenses  increased $192 million or
8.0%,  excluding  restructuring  and other  charges,  due to  increased  capital
expenditures to support our telecommunications  network services, to provide for
growth  in  calling  volumes,   to  introduce  new  technology  and  to  enhance
reliability.  Also contributing to the increase was amortization associated with
the acquisition of the remaining interest in LIN Broadcasting  Corporation (LIN)
in October 1995.

     Selling, general and administrative  expenses,  excluding $1,245 million of
restructuring and other charges in 1995 and $246 million of McCaw merger-related
expenses in 1994, were 29.3% of communications  services revenues in 1996, 27.1%
in  1995  and  24.8%  in  1994.   These  costs  increased  as  a  percentage  of
communications  services  revenues in both 1996 and 1995 due to expenditures for
new  initiatives,  higher  marketing  and sales  expenses  and  enhancements  to
customer care facilities.

     Our  initiatives  for online  services,  such as AT&T  WorldNet(sm),  local
expansion and our consulting and outsourcing businesses represented about 30% of
our increase in 1996 and approximately 15% of our increase in 1995.

     These  increases were slightly  offset in 1996 by lower costs per point for
our True Rewards  program as well as the expiration of some True Rewards points.
Additionally,  further offsetting the 1996 increase were cost reduction benefits
obtained from the 1995 restructuring.

     Also  included in selling,  general and  administrative  expenses were $640
million,  $563 million and $463 million of research and development  expenses in
1996, 1995 and 1994, respectively. Research and development expenditures are

<PAGE>

mainly for work on wireless  technology,  advanced communications  services and
projects aimed at international  growth.  These expenses  included $6 million of
restructuring and other charges in 1995.

(1) Reflects  revenues  from owned  receivables  only.  Owned  receivables  as a
percentage  of total owned and managed  receivables  were 52% in 1996 and 75% in
1995.

     Our  financial  services  segment  is  primarily  our AT&T  Universal  Card
Services business.  Contributing to a lesser degree are some finance assets that
we retained from AT&T Capital as a result of their 1993 restructuring. Universal
Card  continued  to  experience   competitive   pricing   pressures  and  higher
charge-offs  in 1996, as did the industry.  The reserve for credit losses is set
based on  experience,  current  delinquencies  and the outlook for the  economy.
Revenues have  decreased in 1996 compared with 1995  primarily due to the impact
of securitizations we completed during 1995 and 1996.  Additionally,  lower rate
offers continued to decrease margins. In 1995 revenues increased due to a higher
level of average owned receivables.  Universal Card's total managed  receivables
included $6,500 million and $3,500 million of cumulative securitized receivables
at the end of 1996 and 1995, respectively.  Universal Card retains the servicing
and customer  relationships  of the credit card accounts that were  securitized.
Financial services expenses  decreased $356 million or 18.2% in 1996,  excluding
$6 million in 1995 for restructuring and other charges. This decrease reflects a
decrease in overall direct portfolio expenses  (interest,  provisions for credit
losses and other related  costs) due to decreased  owned  receivables  primarily
associated with the securitization program.  Selling, general and administrative
expenses increased $83 million primarily due to customer loyalty programs.

     Financial  services  operating  income  decreased $236 million in 1996, and
increased  $84  million  in 1995,  excluding  restructuring  and other  charges.
Operating margin was 3.8% in 1996, 13.3% in 1995 and 11.8% in 1994. The decrease
in 1996 was primarily due to the continued declinein portfolio credit

<PAGE>

performance and increased  selling,  general and  administrative expenses.  The
increase in 1995 was due to a higher level of average earning assets.

Other Income Statement Line Items

     Other income - net includes sales and exchanges of cellular properties, net
equity earnings from investments, increases in the value of corporate-owned life
insurance  policies on officers,  minority owners'  interests in the earnings or
losses of subsidiaries and other miscellaneous transactions.

     In  addition  to the above,  other  income for 1996  included a loss on our
investment  in Novell,  Inc.  stock and other income for 1994  included the loss
from a lost satellite and preferred dividends of a subsidiary.

     Interest  expense  decreased in 1996 compared with 1995 due to lower levels
of average debt. The lower levels of average debt are primarily  attributable to
the  assignment of debt to Lucent and the  application  of the proceeds from the
sale of AT&T Capital. Interest expense in 1995 compared with 1994 increased as a
result of higher levels of average debt offset  partially by lower average rates
on long-term debt.

     The  effective  income  tax rate is the  provision  for  income  taxes as a
percentage  of income  from  continuing  operations  before  income  taxes.  The
effective  income  tax  rate  for 1996 of 36.7%  was  impacted  by tax  benefits
associated with various legal entity  restructurings.  The 1995 effective income
tax rate of 39.0% was impacted by the restructuring and other charges. Excluding
such charges,  our 1995 effective  income tax rate was 36.7% which was favorably
impacted  by lower  state  tax  rates  and  higher  research  credits.  The 1994
effective income tax rate of 39.3% was impacted by McCaw merger-related expenses
as well as a tax  benefit  of $74  million  as a result of the  redemption  of a
subsidiary's  preferred stock. Excluding these charges, our effective income tax
rate for 1994 was 38.8%.

     Income from discontinued  operations was $138 million in 1996, $251 million
in 1995 excluding  restructuring  and other charges of $3,317 million,  and $317
million in 1994. Income from discontinued operations includes the results of NCR
and other  businesses,  and the  results  of  Lucent  and AT&T  Capital  through
September 30, 1996. As a result, the decline in 1996 relates primarily to Lucent
and AT&T Capital  being  included  for only a portion of the year.  Discontinued
operations  also  includes the  elimination  of  intercompany  transactions,  an
allocation  of  AT&T's  interest  expense  (based  on a ratio of net  assets  of
discontinued  operations to total AT&T  consolidated  assets),  and a portion of
AT&T's consolidated taxes attributable to discontinued businesses. We recognized
a $162  million  after-tax  gain  on the  sale  of AT&T  Capital  as a  separate
component  of  discontinued  operations  in 1996.  Included  in 1996 income from
discontinued operations in 1996.

<PAGE>

     Included in 1996 income from discontinued  operations is a nonrecurring tax
benefit of $155 million as a result of reversing deferred tax liabilities on the
earnings of Lucent's non-U.S.  consolidated subsidiaries.  The subsidiaries have
the ability and specific  intention to permanently  reinvest such  undistributed
earnings.  These  deferred  tax  liabilities  reduced  income from  discontinued
operations in earlier years.

Financial Condition and Cash Flows

Operating  activities.  Cash flow from  operating  activities  decreased 3.6% to
$8,734  million  in 1996 and  increased  14.0% to $9,060  million  in 1995.  The
decrease in 1996 related to required cash payments for  restructuring  and other
charges  amounting  to $471  million.  We expect that  another $1.4 billion will
require  future cash  payments.  The  increase in 1995 was  consistent  with the
growth in our income from continuing  operations,  excluding  restructuring  and
other charges.

     EBITDA (earnings before interest, taxes, depreciation and amortization) for
our  communications  services  business  was  $11,938  million in 1996,  $11,098
million in 1995 (excluding  restructuring and other charges) and $10,138 million
in 1994 (excluding merger-related expenses). The increase in EBITDA in both 1996
and  1995   relates  to  a  higher  level  of  revenues  and  lower  access  and
interconnection  expenses.  EBITDA is a measure of our ability to generate  cash
flows,  and should be  considered  in addition to, but not as a substitute  for,
other measures of financial  performance  reported in accordance  with generally
accepted accounting principles.

Investing activities. We used $1,490 million in 1996, $8,987 million in 1995 and
$7,276  million in 1994 for  investing  activities.  Included in 1996  investing
activities were net capital expenditures, proceeds received from securitizations
and proceeds  received  from  divestments,  including  the sale of AT&T Capital.
Capital  expenditures  (primarily  associated  with  our  network  and  wireless
infrastructure), acquisitions of businesses and investments and the acquisitions
of PCS and cellular  licenses  were  approximately  $7.3 billion in 1996,  $10.0
billion in 1995 and $3.9 billion in 1994.  This resulted in net cash outlays for
the  foregoing in each of 1996,  1995 and 1994 of  approximately  $6.9  billion,
$10.1 billion and $3.8 billion, respectively.

     In 1996 we  continued to invest in our  communications  network in order to
increase capacity,  reliability and enhance network  intelligence to provide new
products and services.  This included the  continued  deployment of  Synchronous
Optical Network  Technology  (SONET) for our long distance  network,  as well as
SONET rings which provide  millisecond  restoration of traffic in the event of a
fiber cut.  We also  invested  in  switching  system  software  associated  with
advanced call  features.  Further,  we expanded our wireless  infrastructure  to
provide higher capacity and improve service quality.  Substantial investments in
our communications  services business are expected to continue as we upgrade our
network and invest in new markets.

<PAGE>

     Competition  in   communications   is  global  and  increasingly   involves
multinational firms and partners.  We believe commitments of resources to expand
globally are necessary for future  growth.  For example,  we have  established a
presence in the United  Kingdom to compete  directly with the dominant  national
provider.

     Also  contributing  to  investing  activities  is  our  financial  services
business.  Securitizations  of credit card  receivables  brought in cash of $3.0
billion in 1996 and $3.5 billion in 1995. Securitization may continue to be used
as a financing alternative in the future.

Financing  activities.  Cash used for financing activities was $5,381 million in
1996 and $222 million in 1994.  In 1995  financing  activities  provided cash of
$1,420  million.  AT&T has  raised  all  necessary  external  financing  through
issuances  of  commercial  paper and  long-term  debt,  as well as  asset-backed
securities (the Universal Card securitizations) and equity. We expect to be able
to arrange any necessary  future  financing  using these same sources,  with the
timing  of  issue,  principal  amount  and form  depending  on our needs and the
prevailing market and economic conditions.

     During  1996 we retired  long-term  debt of $1,236  million  and  decreased
short-term  debt by $5,302  million.  The  changes  in debt  reflect  the use of
alternative sources of funding,  such as securitizations,  as well as the impact
of Lucent obtaining its own external financing in 1996.  Additionally,  the cash
collection  of  the  $2.0  billion  in  accounts  receivable  retained  by  AT&T
continuing operations as part of the restructuring plan and the proceeds of $1.8
billion from the sale of AT&T Capital were used to pay down our debt.

     In 1995 we retired  $2,137  million of  long-term  debt,  but  borrowed  an
additional  $2,392  million of long-term  debt and $1,939  million of short-term
debt. In 1994 we retired $4,078  million in long-term  debt and borrowed  $3,422
million of long-term debt and $1,217 million of short-term debt.

     In each of the past three  years,  we issued new shares of common  stock in
our shareowner and employee benefit stock-ownership plans. In 1997 stock used in
our shareowner and employee benefit  stock-ownership plans will now be purchased
in the stock  market  instead of using  unissued or treasury  shares.  This will
minimize the  dilutive  effects of these plans on equity  shareowners,  but will
require us to use cash to purchase the shares.  We also paid dividends of $2,122
million in 1996, $2,088 million in 1995 and $1,870 million in 1994.

<PAGE>

     On a limited basis, we use certain derivative  financial  instruments in an
effort to manage  exposure to interest rate risk and foreign  exchange risk. Our
utilization of these  instruments  is limited to interest rate swap  agreements,
forward  contracts and options in foreign  currencies to hedge exposures.  We do
not enter into such instruments for speculative  purposes.  All hedging activity
is in accordance with  board-approved  policies.  Any potential loss or exposure
related  to our use of  derivative  instruments  is  immaterial  to our  overall
operations,   financial  condition  and  liquidity.   The  notional  amounts  of
derivative  contracts do not  represent  direct  credit  exposure or future cash
requirements.  Credit  exposure is  determined by the market value of derivative
contracts that are in a gain position as well as the ability of the counterparty
to perform its payment obligations under the agreements.  We control credit risk
of our derivative contracts through credit approvals,  exposure limits and other
monitoring procedures.  There were no past due amounts related to our derivative
contracts  at December  31,  1996,  nor have we ever  recorded  any  charge-offs
related to derivative contracts.

     Total  assets  decreased  from the end of 1995  primarily  due to lower net
assets of discontinued  operations,  finance  receivables  and current  deferred
income taxes. The decrease in net assets of discontinued operations is primarily
due to the  dispositions  of  Lucent,  NCR and AT&T  Capital  in  1996.  Finance
receivables  decreased  mainly due to the Universal  Card  securitizations.  The
decrease  in  current  deferred  income tax  assets is  partially  offset by the
decrease in long-term  deferred income tax liabilities.  These decreases reflect
the portion of long-term  deferred  income tax liabilities at year-end 1995 that
became current in 1996.

     The  decreases  in assets were  partially  offset by increases in property,
plant and equipment and accounts receivable. The increase in property, plant and
equipment  was primarily  due to capital  expenditures  for the AT&T network and
wireless  infrastructure.  The increased  accounts  receivable was driven by our
increased revenues.

     Total  liabilities  decreased from December 31, 1995 primarily due to lower
short- and long-term debt, deferred income taxes and other long-term liabilities
and deferred credits. The lower levels of debt are primarily attributable to the
Universal Card securitization program, the assignment of debt to Lucent, and the
application  of the cash received from the $2.0 billion in retained  receivables
from Lucent and the proceeds from the sale of AT&T Capital.  Long-term  deferred
income tax liabilities  declined due to the  reclassification of deferred income
taxes to current as discussed  above.  Other long-term  liabilities and deferred
credits were down  primarily  due to certain  restructuring-related  liabilities
becoming current.

     These  decreases  were offset by  increases  in accounts  payable and other
current  liabilities.  Increased  accounts  payable relate to increased  capital
expenditures, higher international settlement payables due to timing of payments
and payables related to increased marketing and sales efforts. Increased current

<PAGE>

liabilities reflect increased current taxes payable due primarily
to the sale of
AT&T Capital.

     Shareowners'  equity was $20,295  million at December  31, 1996 and $17,274
million at December  31, 1995.  The increase is due  primarily to net income and
shares issued under employee plans offset  primarily by the impact of the Lucent
and NCR spin-offs of approximately $2.2 billion and dividends of $2.1 billion.

     The ratio of total debt to total  capital  (debt plus equity)  decreased to
33.8% at December 31, 1996,  compared  with 54.5% at December 31, 1995.  Most of
our debt supports financial services  operations.  Excluding financial services,
our debt  ratio was  18.7% at the end of 1996 and  41.3% at the end of 1995.  In
1996 we reduced our debt levels significantly as discussed above. The 1995 ratio
was higher because of the restructuring and other charges and by the issuance of
additional  debt to finance the  acquisitions  of PCS licenses and the remaining
48% of LIN. Additionally,  we had approximately $6.0 billion of unused available
lines of credit at December 31, 1996.

     The fair value of our  pension  plan assets is greater  than our  projected
pension  obligations.  We record pension income when our expected return on plan
assets  plus the  amortization  of the  transition  asset  (created  by our 1986
adoption of the current  standard  for pension  accounting)  is greater than the
interest  cost on our  projected  benefit  obligation  plus service cost for the
year. Consequently we continued to have pension income that added to our prepaid
pension asset in 1996.

Legislative Developments, Regulatory Developments and Competition

     In   February   1996   the   Telecommunications   Act   became   law.   The
Telecommunications  Act,  among  other  things,  was  designed  to foster  local
exchange  competition  by  establishing  a  regulatory  framework  to govern new
competitive entry in local and long distance  telecommunications  services.  The
Telecommunications  Act permits RBOCs to provide  interexchange  services  after
demonstrating  to the FCC that such  provision  is in the  public  interest  and
satisfying the conditions for developing  local  competition  established by the
Telecommunications Act.

     In August  1996 the FCC adopted  rules and  regulations  (the  Implementing
Rules) to implement the local competition  provisions of the  Telecommunications
Act. The Implementing Rules rely on each state to develop the specific rates and
procedures  in  such  state  within  the  framework  prescribed  by the  FCC for
developing such rates and procedures. In October 1996 the United States Court of
Appeals for the 8th circuit  ordered a stay of the  effectiveness  of certain of
the  Implementing  Rules until such court resolves  challenges  thereto by local
telephone companies and telephone regulators in several states.

<PAGE>

     We believe  that such stay may inhibit  the  establishment  of  appropriate
permanent  rates for the provision of network  elements and wholesale  services.
Absent full  effectiveness  of the stayed  Implementing  Rules,  each state will
determine the applicable  rates and  procedures  independent of the framework of
the  Implementing  Rules.  Since the stay was issued,  many states have used the
Implementing  Rules as guidelines in establishing  interim rates that will apply
pending the  determination of permanent rates in subsequent  state  proceedings.
Nevertheless,  in  the  absence  of  the  Implementing  Rules,  there  can be no
assurance  that the prices and other  conditions  established in each state will
provide for effective local service entry and competition or provide us with new
market opportunities.

     In addition  to the  matters  referred  to above,  various  other  factors,
including  market  acceptance,  start-up and ongoing costs  associated  with the
provision of new services and local  conditions and obstacles,  could  adversely
affect the timing and success of our entrance into the local  exchange  services
market and our ability to offer  combined  service  packages  that include local
service.  Because  it is widely  anticipated  that  substantial  numbers of long
distance customers will seek to purchase local, interexchange and other services
from a  single  carrier  as part of a  combined  or full  service  package,  any
competitive  disadvantage,  inability to  profitably  provide  local  service at
competitive  rates or  delays or  limitations  in  providing  local  service  or
combined  service  packages  could  adversely  affect  our future  revenues  and
earnings. In addition, the simultaneous entrance of numerous new competitors for
interexchange  and combined  service  packages is likely to adversely affect our
long distance revenues and could adversely affect earnings.

     We currently face significant  competition in the  communications  services
industry and expect that the level of competition will continue to increase. The
Telecommunications   Act  has  already  begun  to  intensify   the   competitive
environment in recent months.  Non-RBOC local exchange  carriers,  which are not
required to implement the  Telecommunications Act competitive checklist prior to
offering  long  distance  in their  home  markets,  anticipating  changes in the
industry,  have  begun  integrating  their  local  service  offerings  with long
distance  offerings  in advance of AT&T being able to offer  combined  local and
long  distance  service  in these  areas.  In  addition,  most of the RBOCs have
indicated  their  intention  to petition the FCC during 1997 for  permission  to
offer interexchange services in one or more states within their home regions.

Recent Pronouncements

     In June 1996 the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting  Standards  (SFAS) No. 125,  "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities." This statement
requires  that  liabilities  incurred or obtained  by  transferors  as part of a
transfer of financial assets be initially measured at fair value, if practical.

<PAGE>

     It also  requires that  servicing  assets and other  retained  interests in
transferred  assets be  recognized  and  measured  by  allocating  the  previous
carrying  amount  between  assets sold and retained  interests  based upon their
relative  fair values at the date of transfer.  The  statement is effective  for
transfers and servicing of financial assets and  extinguishments  of liabilities
occurring  after  December  31,  1996,  and early  adoption is  prohibited.  The
adoption of this  standard will not have a material  impact on our  consolidated
financial statements.

REPORT OF MANAGEMENT

     Management is responsible for the preparation, integrity and objectivity of
the financial  statements and all other financial  information  included in this
report.  Management  is also  responsible  for  maintaining a system of internal
controls  as  a  fundamental  requirement  for  the  operational  and  financial
integrity of results.

     The financial  statements,  which reflect the consolidated accounts of AT&T
Corp.  and  subsidiaries  (AT&T) and other  financial  information  shown,  were
prepared in conformity with generally accepted accounting principles.  Estimates
included  in the  financial  statements  were based on  judgments  of  qualified
personnel.

     To maintain its system of internal controls,  management  carefully selects
key  personnel  and  establishes  the  organizational  structure  to  provide an
appropriate  division of  responsibility.  We believe it is essential to conduct
business  affairs in accordance with the highest ethical  standards as set forth
in the AT&T Code of Conduct.  These guidelines and other informational  programs
are  designed  and  used to  ensure  that  policies,  standards  and  managerial
authorities are understood  throughout the  organization.  Our internal auditors
monitor  compliance  with the system of internal  controls by means of an annual
plan of internal audits. On an ongoing basis, the system of internal controls is
reviewed, evaluated and revised as necessary in light of the results of constant
management  oversight,  internal  and  independent  audits,  changes  in  AT&T's
business and other conditions.

     Management believes that the system of internal controls, taken as a whole,
provides reasonable assurance that (1) financial records are adequate and can be
relied upon to permit the preparation of financial statements in conformity with
generally accepted accounting principles and (2) access to assets occurs only in
accordance with management's authorizations. The Audit Committee of the Board of
Directors,  which  is  composed  of  directors  who  are  not  employees,  meets
periodically  with  management,   the  internal  auditors  and  the  independent
accountants  to review  the  manner in which  these  groups of  individuals  are
performing  their  responsibilities  and to  carry  out  the  Audit  Committee's
oversight  role with  respect  to  auditing,  internal  controls  and  financial
reporting matters. Periodically,  both the internal auditors and the independent
accountants meet privately with the Audit Committee. These accountants also have
access to the Audit Committee and its individual members at any time.

     The financial statements in this annual report have been audited by Coopers
& Lybrand  L.L.P.,  Independent  Accountants.  Their  audits were  conducted  in
accordance with generally  accepted auditing standards and include an assessment
of the internal  control  structure and selective tests of  transactions.  Their
report follows.



Richard W. Miller                             Robert E. Allen

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareowners of AT&T Corp.:

     We  have  audited  the  consolidated  balance  sheets  of  AT&T  Corp.  and
subsidiaries (AT&T) at December 31, 1996 and 1995, and the related  consolidated
statements  of  income,  changes in  shareowners'  equity and cash flows for the
years ended December 31, 1996, 1995 and 1994. These financial statements are the
responsibility of AT&T's management. Our responsibility is to express an opinion
on these financial statements based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all  material  respects,  the  consolidated  financial  position  of  AT&T at
December 31, 1996 and 1995, and the consolidated results of their operations and
their  cash flows for the years  ended  December  31,  1996,  1995 and 1994,  in
conformity with generally accepted accounting principles.

(a) The net  impact of the  spin-offs  of Lucent  and NCR on total  shareowners'
equity was $2,199 million.

     In March  1990 we  issued  13.4  million  new  shares  of  common  stock in
connection  with the  establishment  of an ESOP  feature  for the  nonmanagement
savings plan. The shares are being allocated to plan participants over ten years
commencing  in July 1990 as  contributions  are made to the plan.  In connection
with the Lucent  spin-off,  $106  million  of the  unamortized  guaranteed  ESOP
obligation was assumed by Lucent.

     We have 100 million  authorized  shares of preferred stock at $1 par value.
No preferred stock is currently issued or outstanding.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AT&T CORP. AND SUBSIDIARIES (AT&T)
(Dollars in millions, except per share amounts)


1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION

     The   consolidated   financial   statements   include  all   majority-owned
subsidiaries.  Investments in which we exercise significant  influence but which
we do not control  (generally a 20% - 50% ownership  interest) are accounted for
under the equity  method of  accounting.  This  represents  the  majority of our
investments.  Generally,  investments in which we have less than a 20% ownership
interest are accounted for under the cost method of accounting.

CURRENCY TRANSLATION

     For  operations  outside of the U.S. that prepare  financial  statements in
currencies other than the U.S. dollar,  we translate income statement amounts at
average  exchange rates for the year, and we translate assets and liabilities at
year-end exchange rates. We present these translation  adjustments as a separate
component of shareowners' equity.

REVENUE RECOGNITION

     We recognize  wireline and wireless  services revenue based upon minutes of
traffic  processed and contracted  fees.  Generally,  we recognize  products and
other services revenue in accordance with contract terms. Our financial services
revenue  is  recognized  over  the life of the  finance  receivables  using  the
interest method.

ADVERTISING COSTS

     We expense  costs of  advertising  as  incurred.  Advertising  expense  was
$2,667, $2,148 and $2,050 in 1996, 1995 and 1994, respectively.

INVESTMENT TAX CREDITS

     We amortize  investment  tax credits as a reduction  to the  provision  for
income taxes over the useful lives of the property that produced the credits.

EARNINGS PER SHARE

     We use the  weighted-average  number of shares of common  shares and common
share equivalents  outstanding during each period to compute earnings per common
share.  Common share  equivalents  are stock options assumed to be exercised for
purposes of this computation.

<PAGE>

STOCK-BASED COMPENSATION

     We apply the intrinsic value based method of accounting for our stock-based
compensation  plans, and except for certain plans, we do not record compensation
expense.

CASH EQUIVALENTS

     We consider all highly  liquid  investments  with  original  maturities  of
generally three months or less to be cash equivalents.

PROPERTY, PLANT AND EQUIPMENT

     We state  property,  plant and  equipment  at cost,  unless  impaired,  and
determine  depreciation  based upon the  assets=  estimated  useful  lives using
either the group or unit method.  The group method is used for most  depreciable
assets.  When we sell or retire  assets  that were  depreciated  using the group
method,  we deduct the cost from property,  plant and equipment and  accumulated
depreciation.  The unit method is used primarily for large computer  systems and
undersea  submarine cables.  When we sell assets that were depreciated using the
unit method, we include the gains or losses in operating results.

     We use accelerated  depreciation  methods  primarily for digital  equipment
used in the telecommunications network, except for switching equipment placed in
service before 1989 and certain high technology computer  processing  equipment.
All other plant and equipment is depreciated on a straight-line basis.

     Long-lived assets are reviewed for impairment whenever events or changes in
circumstances  indicate that the carrying amount may not be recoverable.  If the
sum of the  expected  future  undiscounted  cash flows is less than the carrying
amount of the asset, a loss is recognized  for the  difference  between the fair
value and carrying value of the asset.

LICENSING COSTS

     Licensing costs are costs incurred to develop or acquire cellular, personal
communications  services (PCS) and messaging licenses.  Generally,  amortization
begins with the  commencement  of service to customers and is computed using the
straight-line method over a period of 40 years.

GOODWILL

     Goodwill  is the  excess of the  purchase  price over the fair value of net
assets acquired in business combinations accounted for as purchases. We amortize
goodwill on a straight-line  basis over the periods  benefited ranging from 5 to
40 years.  Goodwill is reviewed for  impairment  annually or whenever  events or
changes  in  circumstances   indicate  that  the  carrying  amount  may  not  be
recoverable.  If the sum of the expected future  undiscounted cash flows is less
than the carrying  amount,  a loss is recognized for the difference  between the
fair value and carrying value of the asset.

DERIVATIVE FINANCIAL INSTRUMENTS

     We  use  various  financial  instruments,  including  derivative  financial
instruments, for purposes other than trading. We do not use derivative financial
instruments  for  speculative  purposes.  Derivatives,  used as part of our risk
management strategy, must be designated at inception as a hedge and measured for
effectiveness  both at inception and on an ongoing basis.  Gains and losses that
do not qualify as hedges are recognized in other income - net.

<PAGE>

USE OF ESTIMATES

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements, and revenues and expenses during the period reported. Actual results
could  differ  from those  estimates.  Estimates  are used when  accounting  for
certain  items such as long-term  contracts,  allowance  for doubtful  accounts,
depreciation  and  amortization,  employee benefit plans,  taxes,  restructuring
reserves and contingencies.

RECLASSIFICATIONS

     We reclassified certain amounts for previous years to conform with the 1996
presentation.


2.  DISCONTINUED OPERATIONS

     On  September  20,  1995,  AT&T  announced  a  plan,   subject  to  certain
conditions, to separate into three independent, publicly held, global companies:
communications services (AT&T),  communications systems and technologies (Lucent
Technologies   Inc.,   "Lucent")  and   transaction-intensive   computing   (NCR
Corporation,  "NCR").  In April 1996 Lucent  sold 112  million  shares of common
stock in an initial  public  offering  (IPO),  representing  17.6% of the Lucent
common stock outstanding. Because of AT&T's plan to spin off its remaining 82.4%
interest  in Lucent,  the sale of the  Lucent  stock was  recorded  as an equity
transaction,  resulting in an increase in AT&T's  additional  paid-in capital at
the time of the IPO. In addition,  in connection with the restructuring,  Lucent
assumed  $3.7  billion  of AT&T  debt in  1996.  On  September  30,  1996,  AT&T
distributed  to AT&T  shareowners  of  record  as of  September  17,  1996,  the
remaining  Lucent common stock held by AT&T. The shares were  distributed on the
basis of .324084 of a share of Lucent for each AT&T share outstanding.

     Also announced as part of the  separation  plan was AT&T's intent to pursue
the sale of its remaining  approximate 86% interest in AT&T Capital  Corporation
(AT&T  Capital).  On October 1, 1996,  AT&T sold its remaining  interest in AT&T
Capital for approximately $1.8 billion, resulting in a gain of $162, or $.10 per
share, after taxes.

     On December 31, 1996, AT&T also  distributed all of the outstanding  common
stock of NCR to AT&T  shareowners  of record as of December 13, 1996. The shares
were  distributed  on the basis of .0625 of a share of NCR for each  AT&T  share
outstanding on the record date. As a result of the Lucent and NCR distributions,
AT&T's shareowners' equity was reduced by $2.2 billion. The distributions of the
Lucent and NCR common stock to AT&T shareowners were noncash  transactions which
did not affect  AT&T's  results of  operations.  The  distribution  of NCR stock
completed  AT&T's  strategic  restructuring  plan as announced on September  20,
1995.

     The consolidated financial statements of AT&T have been restated to reflect
the dispositions of Lucent, NCR and AT&T Capital and the planned dispositions of
other businesses as discontinued  operations.  Accordingly,  the revenues, costs
and  expenses,  assets and  liabilities,  and cash flows of  Lucent,  NCR,  AT&T
Capital and other businesses have been excluded from the respective  captions in
the  Consolidated   Statements  of  Income,   Consolidated  Balance  Sheets  and
Consolidated  Statements of Cash Flows, and have been reported through the dates
of  disposition  as  "Income  (loss)  from  discontinued   operations,"  net  of
applicable income taxes; as "Net assets of discontinued operations"; and as "Net
cash used in discontinued operations" for all periods presented.

<PAGE>

     Summarized  financial  information  for the  discontinued
operations is as
follows:

                                           1996       1995        1994
          Revenues                      $22,341    $28,945     $27,318

            income taxes                   (236)    (4,320)        278
          Net income (loss)                 138     (3,066)        317
          Current assets                    554     17,415
          Total assets                      862     34,181
          Current liabilities               230     14,787
          Total liabilities                 336     26,755
          Net assets of discontinued
            operations                  $   526    $ 7,426

     The income (loss) before income taxes includes  allocated  interest expense
of $45, $134 and $198 in 1996, 1995 and 1994, respectively. Interest expense was
allocated  to  discontinued  operations  based  on a  ratio  of  net  assets  of
discontinued operations to total AT&T consolidated assets.


3.  CHANGES IN ACCOUNTING PRINCIPLES

     In 1997 we will adopt Statement of Financial  Accounting  Standards  (SFAS)
No. 125,  "Accounting  for  Transfers  and  Servicing  of  Financial  Assets and
Extinguishments of Liabilities." Among other provisions,  this standard requires
that in connection with the transfer of financial assets,  liabilities  incurred
should be measured at fair value and retained  interests should be recorded as a
portion of the original carrying amount of the transferred financial assets. The
adoption  of this  standard  will not have a material  impact on our  results of
operations, financial position or cash flows.

     On  September  30, 1996 AT&T  distributed  to AT&T  shareowners  all of the
remaining  82.4% of Lucent  common  stock held by AT&T,  resulting  in a noncash
distribution of $2.7 billion. Also, on December 31, 1996 AT&T distributed all of
the  outstanding  stock  of NCR to  AT&T  shareowners,  resulting  in a  noncash
distribution of $2.1 billion.

     In 1995 we acquired the remaining 48% of LIN Broadcasting Corporation (LIN)
for  approximately  $3.3 billion.  The purchase  price was allocated to the fair
value of assets  acquired  of $4.0  billion  and the fair  value of  liabilities
assumed of $.7 billion.

5.  BUSINESS RESTRUCTURING AND OTHER CHARGES

     In the  fourth  quarter of 1995 we  recorded  a pretax  charge of $3,029 to
cover  restructuring  costs of $2,307 and asset impairments and other charges of
$722.  This  charge  included  plans to exit  certain  proprietary  network  and
messaging services; restructure customer service organizations; consolidate call
servicing centers; exit certain satellite services; reorganize corporate support
functions such as information systems, human resources and financial operations;
and restructure certain international operations.

     As part of our  plan to sell  certain  businesses  and to  restructure  our
operations,  restructuring  liabilities  of $1,718 were  recorded  for  employee
separation costs, costs associated with early termination of building leases and
other items. In addition,  asset impairments of $567 (which directly reduced the
carrying  value of the related  asset  balances)  and $22 of benefit plan losses
were  recorded.  Benefit  plan losses  relate to our pension and other  employee
benefit plans and primarily  represent  losses in the current year for actuarial
changes that otherwise might have been amortized over future periods.

     The 1995 restructure charge of $2,307 included  separation costs for nearly
17,000  employees,  which  included  approximately  12,000  management and 5,000
occupational employees. As of December 31, 1996,  approximately 5,000 management
employees and 1,000  occupational  employees have been  separated.  Of the 5,000
management  sepa  rations,  approximately  3,000  accepted  voluntary  severance
packages.

     During 1996 we completed the  restructuring of our proprietary  network and
messaging services business, closed several call servicing centers, sold certain
international  operations and reorganized  certain corporate support  functions.
The implementation of certain restructuring activities are occurring at a slower
pace than  planned.  There have been delays in exiting  certain  businesses  and
reorganizing   corporate  support   functions,   in  part,  to  ensure  customer
satisfaction  during this transition period. We expect the majority of our plans
to be completed during 1997. However,  certain severance and facility costs have
payment terms extending  beyond 1997. We believe that the balance is adequate to
complete these plans.

<PAGE>

     The following  table displays a rollforward of the liabilities for business
restructuring from December 31, 1994 to December 31, 1996:

     Utilization   primarily   represents   cash   payments  and  other  noncash
utilization of restructuring reserves. 1996 noncash utilization includes $112 of
net transfers to Lucent and NCR.

     The December 31, 1994  business  restructuring  balance  included  reserves
primarily for real estate and reengineering  operator  services.  As of December
31, 1996, $319 of the $699 December 31, 1994 balance  remained.  This balance is
primarily  related to excess space in various leased  facilities and is expected
to be fully  utilized  over the  remaining  terms of the leases.  The balance is
adequate to complete these plans.

     The 1995 charge of $722 for asset  impairments  and other charges  included
$668 for writing down certain impaired  assets,  including the write-down in the
value of some  unnecessary  network  facilities,  the write-down of nonstrategic
wireless  assets and the reduction in value of some  investments.  There were no
assets to be disposed of or sold included in these write-downs.  The charge also
included $54 of other items, none of which  individually  exceed 1% of the total
charge.

     The total pretax  charge of $3,029 for 1995 was recorded as $844 in network
and other communications services; $934 in depreciation and amortization; $1,245
in selling,  general and administrative;  and $6 in financial services expenses.
If  viewed by type of cost,  the  combined  charges  reflect  $956 for  employee
separations  and other related  items;  $1,235 for asset  write-downs;  $497 for
closing,  selling and  consolidating  facilities;  and $341 for other items. The
total charge reduced income from continuing  operations by $2,036,  or $1.28 per
share.

<PAGE>

     In addition,  charges of $1,172 (net of taxes) in the third quarter of 1995
and $2,145  (net of taxes) in the fourth  quarter of 1995 are  reflected  in the
loss  from   discontinued   operations.   These  charges   reduced  income  from
discontinued operations by a total of $3,317, or $2.08 per share in 1995.

     Deferred  income  tax  liabilities  are  taxes we  expect  to pay in future
periods.  Similarly,  deferred  income  tax  assets are  recorded  for  expected
reductions  in taxes  payable in future  periods.  Deferred  income  taxes arise
because  of  differences  in the  book  and tax  bases  of  certain  assets  and
liabilities.

     Deferred income tax liabilities and assets consist of the following:

     At December 31, 1996 we had net operating loss carryforwards (tax effected)
for federal and state income tax purposes of $15 and $57, respectively, expiring
through  2010.  We also  had  foreign  net  operating  loss  carryforwards  (tax
effected)  of $103,  of  which  $96 has no  expiration  date,  with the  balance
expiring by the year 2000. We also had federal tax credit  carryforwards  of $47
which are not  subject to  expiration.  We  recorded a  valuation  allowance  to
reflect the estimated amount of deferred tax assets which, more likely than not,
will not be realized.


7.  EMPLOYEE BENEFIT PLANS

PENSION PLANS

     We sponsor  noncontributory  defined benefit plans covering the majority of
our  employees.  Benefits for  management  employees  are  principally  based on
career-average pay. Benefits for occupational employees are not directly related
to pay.  Pension  contributions  are principally  determined using the aggregate
cost method and are  primarily  made to trust funds held for the sole benefit of
plan participants.

<PAGE>

     Immediately  following the spin-off of Lucent on September 30, 1996, Lucent
established  separate  defined  benefit  plans,  and  a  share  of  the  pension
obligations  and  pension  assets  held in trust were  transferred  from AT&T to
Lucent based on methods and  assumptions  that were agreed to by both companies.
The asset and pension  obligation  amounts that were  transferred  to Lucent are
subject to final  adjustment.  The final amounts to be transferred to Lucent are
not expected to be materially different from the estimated amounts.

     We compute  pension cost using the projected unit credit method and assumed
a long-term rate of return on plan assets of 9.0% in 1996, 1995 and 1994.

     Pension cost includes the following components:

Years ended December 31                      1996       1995        1994
Service cost - benefits earned during
  the period                               $  299     $  203      $  239
Interest cost on projected benefit
  obligation                                  863        748         701
Amortization of unrecognized prior
  service costs                                99         90          73
Credit for expected return on plan
  assets*                                  (1,195)    (1,043)     (1,015)
Amortization of transition asset             (183)      (193)       (193)
Charges for special pension options             -         58           -
Net pension credit                         $ (117)    $ (137)    $  (195)

* The actual  return on plan assets was $2,981 in 1996,  $1,044 in 1995 and $156
in 1994.

     The net pension credit in 1995 includes a one-time  charge of $58 for early
retirement options and curtailments.

     This table shows the funded status of the defined benefit plans:

At December 31                                          1996         1995
Actuarial present value of accumulated benefit
  obligation, including vested benefits of
  $10,083 and $9,874                                 $11,520      $10,959

Plan assets at fair value                            $17,680      $15,294
Less: Actuarial present value of projected
  benefit obligation                                  12,380       11,572
Excess of assets over projected benefit obligation     5,300        3,722
Unrecognized prior service costs                         766          804
Unrecognized transition asset                           (889)      (1,136)
Unrecognized net gain                                 (3,303)      (1,620)
Net minimum liability of nonqualified plans              (51)         (49)
Prepaid pension costs                                $ 1,823    $   1,721

<PAGE>

     We used these rates and  assumptions  to calculate  the  projected  benefit
obligation:

At December 31                                          1996       1995
Weighted-average discount rate                           7.5%       7.0%
Rate of increase in future compensation levels           5.0%       5.0%

     The prepaid  pension costs shown above are net of pension  liabilities  for
plans where  accumulated  plan benefits  exceed  assets.  Such  liabilities  are
included in other liabilities in the Consolidated Balance Sheets.

     We are amortizing over approximately 15.9 years the unrecognized transition
asset related to our 1986 adoption of SFAS No. 87,  "Employers'  Accounting  for
Pensions." We amortize prior service costs  primarily on a  straight-line  basis
over the average remaining  service period of active employees.  Our plan assets
consist  primarily of listed stocks  (including $56 and $61 of AT&T common stock
at December 31, 1996 and 1995,  respectively),  corporate and governmental debt,
real estate investments and cash and cash equivalents.

SAVINGS PLANS

     We sponsor savings plans for the majority of our employees. The plans allow
employees to  contribute a portion of their pretax  and/or  after-tax  income in
accordance  with  specified  guidelines.  We match a percentage  of the employee
contributions up to certain limits. Our contributions  amounted to $180 in 1996,
$159 in 1995 and $134 in 1994.


8.  POSTRETIREMENT BENEFITS

     Our benefit plans for retirees include health care benefits, life insurance
coverage and telephone concessions.

     Immediately  following the spin-off of Lucent on September 30, 1996, Lucent
established  separate   postretirement   benefit  plans,  and  a  share  of  the
postretirement  benefit  obligations and  postretirement  benefit assets held in
trust were transferred from AT&T to Lucent based on methods and assumptions that
were  agreed  to by  both  companies.  The  assets  and  postretirement  benefit
obligations that were transferred to Lucent are subject to final adjustment. The
final  amounts to be  transferred  to Lucent are not  expected to be  materially
different from the estimated amounts.

     This table shows the components of the net postretirement benefit cost:

Years ended December 31                             1996       1995       1994
Service cost - benefits earned during the period    $ 54       $ 41       $ 45
Interest cost on accumulated postretirement

Net postretirement benefit cost                     $260       $241       $231

* The actual  return on plan assets was $313 in 1996,  $256 in 1995 and $(11) in
1994.

     We had approximately  37,900, 34,500 and 34,000 retirees as of December 31,
1996, 1995 and 1994, respectively.

<PAGE>

     Our  plan  assets  consist  primarily  of  listed  stocks,   corporate  and
governmental debt, cash and cash equivalents and life insurance  contracts.  The
following  table shows the funded  status of our  postretirement  benefit  plans
reconciled with the amounts recognized in the Consolidated Balance Sheets:

At December 31
                                                            1996       1995

5.6%       6.1%

     We assumed  that the growth in the per capita  cost of covered  health care
benefits (the health care cost trend rate) would gradually decline after 1996 to
4.7% by the year 2006 and then remain level. This assumption greatly affects the
amounts reported. To illustrate, increasing the assumed trend rate by 1% in each
year would raise our accumulated  postretirement  benefit obligation at December
31, 1996 by $166 and our 1996 postretirement benefit costs by $19.


9.  STOCK-BASED COMPENSATION PLANS

     Under  the  1987  Long-Term  Incentive  Program,  we grant  stock  options,
performance  shares,  restricted  stock and other  awards.  On January 1 of each
year,  0.6% of the outstanding  shares of our common stock become  available for
grant.  The  exercise  price of any stock option is equal to or greater than the
stock price when the option is granted.  Generally,  the options vest over three
years and are  exercisable  up to ten years from the date of grant.  Performance
share units are awarded to key  employees in the form of either  common stock or
cash  at the  end of a  three  year  period  based  on  AT&T's  return-to-equity
performance compared with a target.

     Under the AT&T 1996 Employee Stock Purchase Plan (Plan) which was effective
July 1, 1996, we are authorized to issue up to 50 million shares of common stock
to our eligible employees. Under the terms of the Plan, employees may have up to
10% of their  earnings  withheld to purchase  AT&T's common stock.  The purchase
price of the stock on the date of exercise  is 85% of the  average  high and low
sale  prices of shares on the New York Stock  Exchange  for that day.  Under the
Plan, we sold approximately 3 million shares to employees during 1996.

<PAGE>

     We apply Accounting  Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees," and related  Interpretations  in accounting for our plans.
Accordingly,  no  compensation  expense has been  recognized for our stock-based
compensation  plans other than for our  performance-based  and restricted  stock
awards,  SARs,  and prior to July 1, 1996 for the stock purchase plan for former
McCaw  Cellular  Communications,  Inc.  employees.  Compensation  costs  charged
against income were $41 in 1996.

     Effective  on the dates of spin-off of Lucent and NCR,  AT&T stock  options
held by Lucent and NCR employees were  canceled.  For the holders of unexercised
AT&T stock options,  the number of options was adjusted and all exercise  prices
were decreased immediately following each spin-off date to preserve the economic
values of the options that existed prior to those dates.

     During  1996,  73,145 SARs were  exercised  and no SARs were  granted.  The
number of outstanding SARs was adjusted by 131,088 in connection with the Lucent
and NCR spin-offs. At December 31, 1996, 743,840 SARs remained unexercised,  all
of which were exercisable.

<PAGE>

     AT&T  has  adopted  the   disclosure-only   provisions  of  SFAS  No.  123,
"Accounting  for  Stock-Based  Compensation."  If AT&T had elected to  recognize
compensation  costs  based on the fair  value at the date of grant for awards in
1996 and 1995, consistent with the provisions of SFAS No. 123, AT&T's net income
and earnings per common share would have been reduced to the following pro forma
amounts:

Years ended December 31                              1996
1995
Income from continuing operations                  $5,537
$3,192
Income (loss) from discontinued operations            111
(3,072)
Net income                                         $5,810
$  120

Earnings per common share
Continuing operations                              $ 3.43        $

Discontinued operations                               .07
(1.92)
Net income                                         $ 3.60
$  .08

     Without the effect of pro forma costs related to the  conversion of options
in the Lucent and NCR spin-offs, pro forma income from continuing operations was
$5,567 or $3.44 per share in 1996.

     The  pro  forma  effect  on  net  income  for  1996  and  1995  may  not be
representative of the pro forma effect on net income of future years because the
SFAS No. 123 method of  accounting  for pro forma  compensation  expense has not
been applied to options granted prior to January 1, 1995.

     The  weighted-average  fair  values  at date of grant for  options  granted
during 1996 and 1995 were $13.12 and $14.02,  respectively,  and were  estimated
using the  Black-Scholes  option-pricing  model. The following  assumptions were
applied for periods  before the Lucent  spin-off  and  subsequent  to the Lucent
spin-off,  respectively:  (i) expected  dividend  yields of 2.4% and 2.8%,  (ii)
expected  volatility  rates of 19.0% and 21.0%,  and (iii) expected lives of 5.0
years and 4.5 years. The risk-free interest rates applied for 1996 and 1995 were
6.11% and 6.44%, respectively.

11.  FINANCIAL INSTRUMENTS

     In the normal  course of  business we use  various  financial  instruments,
including derivative financial instruments,  for purposes other than trading. We
do not use derivative  financial  instruments  for speculative  purposes.  These
instruments include commitments to extend credit, letters of credit,  guarantees
of debt,  interest rate swap agreements and foreign currency exchange contracts.
Interest rate swap agreements and foreign currency  exchange  contracts are used
to  mitigate  interest  rate  and  foreign  currency  exposures.  Collateral  is
generally not required for these types of instruments.

     By their nature all such  instruments  involve  risk,  including the credit
risk of  nonperformance  by  counterparties,  and our maximum potential loss may
exceed the amount recognized in our balance sheet. However, at December 31, 1996
and 1995, in management's  opinion there was no significant  risk of loss in the
event of nonperformance of the counterparties to these financial instruments. We
control our exposure to credit risk through credit approvals,  credit limits and
monitoring  procedures and we believe that our reserves for losses are adequate.
We  do  not  have  any  significant  exposure  to  any  individual  customer  or
counterparty,  nor do we have any major  concentration of credit risk related to
any financial instruments.

COMMITMENTS TO EXTEND CREDIT

     We participate  in the  general-purpose  credit card business  through AT&T
Universal  Card  Services  Corp.,  a  wholly  owned   subsidiary.   We  purchase
essentially  all  cardholder  receivables  under an agreement with the Universal
Bank, which issues the cards. The unused portion of available credit was $69,041
at December  31, 1996 and $72,179 at December  31,  1995.  This  represents  the
receivables  we would need to purchase if all Universal  Card accounts were used
up to their full credit limits.  The potential risk of loss associated with, and
the estimated  fair value of, the unused  credit lines are not  considered to be
significant.

LETTERS OF CREDIT

     Letters of credit are purchased  guarantees  that ensure our performance or
payment to third parties in accordance  with specified  terms and conditions and
do not create any additional risk to AT&T.

GUARANTEES OF DEBT

     From time to time we  guarantee  the debt of our  subsidiaries  and certain
unconsolidated joint ventures.  Additionally,  in connection with restructurings
of AT&T, we issued  guarantees for certain debt  obligations of AT&T Capital and
NCR. At December 31, 1996, the amount of guaranteed  debt  associated  with AT&T
Capital and NCR was $230.

<PAGE>

INTEREST RATE SWAP AGREEMENTS

     We enter into  interest  rate swaps to manage  our  exposure  to changes in
interest  rates and to lower our overall costs of financing.  We enter into swap
agreements to manage the  fixed/floating  mix of our debt  portfolio in order to
reduce aggregate risk to interest rate movements. Interest rate swaps also allow
us to raise funds at floating rates and  effectively  swap them into fixed rates
that are lower than those  available to us if  fixed-rate  borrowings  were made
directly.  These agreements involve the exchange of floating-rate for fixed-rate
payments or fixed-rate for  floating-rate  payments  without the exchange of the
underlying  principal amount.  Fixed interest rate payments at December 31, 1996
are at rates  ranging from 4.68% to 7.75%.  Floating-rate  payments are based on
rates tied to prime,  LIBOR or U.S. Treasury bills.  Interest rate differentials
paid or received under these swap contracts are recognized  over the life of the
contracts as  adjustments to the effective  yield of the underlying  debt. If we
terminate a swap agreement, the gain or loss is recorded as an adjustment to the
basis of the  underlying  asset or liability  and  amortized  over the remaining
life.

     The  following  table  indicates  the types of swaps in use at December 31,
1996 and 1995 and their weighted-average  interest rates. Average variable rates
are those in effect at the reporting date and may change  significantly over the
lives of the contracts.

                                                                 1996       1995

  Average receive rate                             6.67%      6.57%
  Average pay rate                                 5.45%      5.62%
Variable to fixed swaps - notional amount        $  351     $  894
  Average receive rate                             5.77%      5.64%
  Average pay rate                                 5.71%      6.05%

     The weighted average  remaining terms of the swap contracts are 4 years for
1996 and 8 years for 1995.

FOREIGN EXCHANGE

     We enter into foreign currency  exchange  contracts,  including forward and
option contracts,  to manage our exposure to changes in currency exchange rates,
principally French francs, Deutsche marks, pounds sterling and Japanese yen. The
use of these derivative  financial  instruments allows us to reduce our exposure
to the risk of adverse  changes in exchange rates on the eventual  reimbursement
to foreign telephone  companies for their portion of the revenues billed by AT&T
for  calls  placed in the U.S.  to a foreign  country.  These  transactions  are
generally  expected  to occur in less than one year.  Gains or losses on foreign
exchange contracts that are designated for forecasted and other foreign currency
transactions are recognized in other income as the exchange rates change.

FAIR VALUES OF FINANCIAL INSTRUMENTS INCLUDING DERIVATIVE
FINANCIAL INSTRUMENTS

     The following table summarizes the notional  amounts of material  financial
instruments.  The  notional  amounts  represent  agreed  upon  amounts  on which
calculations of dollars to be exchanged are based. They do not represent amounts
exchanged by the parties and, therefore,  are not a measure of our exposure. Our
exposure  is  limited to the fair value of the  contracts  with a positive  fair
value plus interest receivable, if any, at the reporting date.

respectively.  For debt excluding capital leases,  the carrying amounts and fair

$21,225, respectively, for 1995.

with  proceeds  received  of $3,000 and  $3,492,  respectively.  We  continue to

CONCENTRATIONS

     As of December 31, 1996 we are not aware of any  significant  concentration
of  business  transacted  with a  particular  customer,  supplier or lender that
could, if suddenly  eliminated,  severely impact our operations.  We also do not
have a concentration  of available  sources of labor,  services,  or licenses or
other rights that could, if suddenly eliminated, severely impact our operations.

13.  AT&T CREDIT HOLDINGS, INC.

     In  connection  with a March 31, 1993 legal  restructuring  of AT&T Capital
Holdings, Inc. (formerly AT&T Capital Corporation), we issued a direct, full and
unconditional  guarantee  of all the  outstanding  public  debt  of AT&T  Credit
Holdings, Inc. (formerly AT&T Credit Corporation).  At December 31, 1996, $59 of
the guaranteed debt remained outstanding.

     AT&T Credit  Holdings,  Inc.  holds the  finance  assets of the former AT&T
Credit  Corporation  and prior to the sale of AT&T  Capital  on October 1, 1996,
held the majority of AT&T's  investment in AT&T  Capital.  The table below shows
summarized consolidated financial information for AT&T Credit Holdings, Inc. The
summarized  financial  information  includes  transactions  with  AT&T  that are
eliminated in consolidation.

14.  COMMITMENTS AND CONTINGENCIES

     In the normal  course of business we are subject to  proceedings,  lawsuits
and other claims,  including  proceedings under laws and regulations  related to
environmental and other matters. Such matters are subject to many uncertainties,
and outcomes are not predictable with assurance.  Consequently, we are unable to
ascertain  the  ultimate  aggregate  amount of monetary  liability  or financial
impact with respect to these  matters at December 31, 1996.  These matters could
affect the operating results of any one quarter when resolved in future periods.
However,  we believe that after final  disposition,  any  monetary  liability or
financial  impact  to us  beyond  that  provided  for at  year-end  would not be
material to our annual consolidated financial statements.

     We lease land,  buildings and equipment  through  contracts  that expire in
various years through 2014. Our rental expense under  operating  leases was $721
in 1996,  $766 in 1995 and $819 in 1994.  The  following  table shows our future
minimum lease payments due under noncancelable  operating leases at December 31,
1996. Such payments total $2,873. The total of minimum rentals to be received in
the future under noncancelable subleases as of December 31, 1996 was $329.

Later Years
       $606       $469       $359       $312       $234
$893

     We have  entered into  agreements  with Lucent and NCR pursuant to which we
will purchase products and services totaling at least $3,000 cumulatively by the
end of 1998 from Lucent and $350 from NCR by the end of 1999. As of December 31,
1996 we  purchased  $2,726 of products  and  services  from Lucent and NCR under
these agreements.

<PAGE>

     In  January  1997  one of our  satellites  went out of  orbital  alignment.
Contact could not be  reestablished  and the satellite was declared  permanently
out  of  service.   Under  various   contracts  related  to  previous  sales  of
transponders associated with this satellite, we are required to either repair or
replace the  transponder or refund portions of the sale price. We have insurance
to  cover a  portion  of our  exposure  under  these  warranties  as well as the
carrying value of the satellite.  We believe that the ultimate  resolution  will
not have a material impact on our results of operations.
