         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
in the
separate agreements provided for below.

                  (a)  MANDATORY  PORTABILITY  AGREEMENT.  Effective  as of  the

shall become,  an  Interchange  Company  under the MPA, with all the  applicable
rights and obligations of such an Interchange  Company.  Each Lucent Entity that

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






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
Purchase Plan;  (vii) mutual  maintenance and recognition by the AT&T Health and
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

(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).


                                   ARTICLE III
                              DEFINED BENEFIT PLANS

         3.1  ESTABLISHMENT  OF MIRROR PENSION  TRUSTS.  Before the Close of the
Distribution  Date, AT&T shall cause the trust presently  established  under the
AT&T  Pension  Plans to be amended and  restated as a group trust under IRS Rev.
Rul. 81-100 (the "AT&T Group Pension  Trust") in a form reasonably  satisfactory
to  Lucent.  AT&T  shall  establish,  or cause to be  established,  a new master
pension  trust  under  the AT&T  Pension  Plans,  which  shall be  substantially
identical  in all  Material  Features  to the trust  established  under the AT&T
Pension Plans as in effect before such amendment and restatement and which shall
be a participating trust in the AT&T Group Pension Trust.  Effective Immediately
after the Distribution Date, Lucent shall establish, or cause to be established,
a master pension trust qualified in accordance with Code Section 401(a),  exempt
from  taxation  under Code  Section  501(a)(1),  and forming  part of the Lucent
Pension Plans,  which shall be a  participating  trust in the AT&T Group Pension
Trust,  subject to ratification of such  participation by the Board of Directors
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
Distribution Date).

         3.2 ASSUMPTION OF PENSION PLAN LIABILITIES AND ALLOCATION
OF INTERESTS
IN THE AT&T MASTER PENSION TRUST.

                  (a)   ASSUMPTION  OF   LIABILITIES  BY  LUCENT  PENSION  PLAN.
Immediately  after the  Distribution  Date,  all  Liabilities  to or relating to
Transferred  Individuals  under  the AT&T MPP or AT&T PP, as  applicable,  shall
cease to be Liabilities of the AT&T MPP or AT&T PP, as applicable,  and shall be
assumed by the corresponding Lucent Pension Plan.







         (b) ASSET ALLOCATIONS AND TRANSFERS.

                  (i) CALCULATION OF ASSET ALLOCATION.

                           (A) As soon as practicable after the
Close of the
Distribution  Date, AT&T shall cause to be calculated,  for the AT&T MPP and the
corresponding  Lucent  Pension Plan, as of  Immediately  after the  Distribution
Date,  (1) the  "Funding  Policy  Amount,"  which shall be  consistent  with the
minimum amount  necessary to satisfy AT&T's pension  funding policy as set forth
in Schedule VI, as applied to the AT&T MPP and the corresponding  Lucent Pension
Plan; (2) the "414(l)(1) Amount," which shall equal the minimum amount necessary
to fully fund benefits under the AT&T MPP and the  corresponding  Lucent Pension
Plan on a "termination  basis" (as that term is defined in Treas.  Reg.  Section
1.414(l)-1(b)(5));  and (3) the "Initial  Allocation  Amount," which shall equal
the Funding Policy Amount for that particular  Pension Plan, plus one-half times
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








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.

                                   ARTICLE IV

                           DEFINED CONTRIBUTION PLANS

    4.1 LTSPMEs AND RSPSPs.

         (a) MANAGEMENT  SAVINGS PLAN TRUSTS.  Effective  Immediately  after the
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
the Lucent
RSPSP shall assume and be solely responsible for all Liabilities
to or relating
to Transferred Individuals under the AT&T LTSPME and the AT&T
RSPSP,
respectively; and (ii) AT&T shall cause






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






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






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






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

post-retirement  benefits of employees not covered by any collective  bargaining

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

                            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,
Rosen & Katz



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






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







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.







                           (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;
(ii) agreed to bear all of the costs of implementing  the amendment  incurred by
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.







                  (b) CHANGES IN VENDOR CONTRACTS, GROUP INSURANCE
POLICIES,
PLAN DESIGN, AND ADMINISTRATION PRACTICES AND PROCEDURES.

                           (i) From Immediately after the
Distribution Date
through the earlier of the expiration of the financial fee or rate guarantees in
effect  as of the  Close of the  Distribution  Date  under  the  applicable  ASO
Contract, Group Insurance Policy or HMO Agreement, and
December  31, 1998,
neither  AT&T nor Lucent  shall  materially  modify,  or take other action which
would have a material effect on, any of the following (each such modification, a
"Change") without complying with Section  5.8(b)(ii):  (A) the termination date,
administration, or operation of (1) an ASO contract between AT&T or Lucent and a
third-party  administrator,  (2) a  Group  Insurance  Policy  issued  to AT&T or
Lucent,  or (3) an HMO Agreement with AT&T or Lucent, in each case, the material
terms and  conditions of which  contracts and policies are extended to Lucent or
to which  Lucent  becomes a party  pursuant  to Section  5.7;  (B) the design of
either an AT&T Health and Welfare Plan or a Lucent  Health and Welfare  Plan; or
(C) the  financing,  operation,  administration  or delivery  of benefits  under
either an AT&T Health and Welfare Plan or a Lucent Health and Welfare Plan.

                           (ii) Neither AT&T nor Lucent shall make
any Change
unless the party  intending  to make the Change  has:  (A) given the other party
written  notice of the  intention to make the Change,  accompanied  by a written
description  of the  Change,  at  least  180  days in  advance  of the  proposed
effective  date  of  the  Change;  (B)  agreed  to  bear  all of  the  costs  of
implementing  the Change which are incurred by all  third-party  administrators,
insurance companies, HMOs and other vendors and passed through to one or both of
the parties;  and (C)  certified  to the other party,  and provided to the other
party the  written  concurrence  of each  third-party  administrator,  insurance
company,  HMO  or  other  vendor  associated  with  or  performing  services  in
connection with the Health and Welfare Plan affected by the Change,  that (after
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
LIFE
INSURANCE  COMMITTEE.  If AT&T or Lucent  desires to make a Change that requires

                  (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
2000  project  or  otherwise,  shall  have  the  right to  engage a  third-party
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.

continuation  coverage  requirements  of COBRA and the Lucent Health and Welfare
plans, and, with respect to Transferred Individuals, the AT&T Health and Welfare
Plans.

        5.14  LEAVE OF ABSENCE PROGRAMS AND FMLA.

                  (a) Through the Close of the Distribution  Date, AT&T shall be
responsible for administering compliance with the AT&T Leave of Absence Programs

determining whether their respective  employees are eligible for leave under the
AT&T Leave of Absence  Programs and FMLA in  accordance  with such  programs and
FMLA, respectively.

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

absence programs which are  substantially  identical in all Material Features to
the AT&T Leave of Absence Programs as in effect on the  Distribution  Date; (ii)
Lucent shall honor,  and shall cause each Lucent Entity to honor,  all terms and

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

        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






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.







                           (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.






        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.

MAXIMUM

                           (i) Lucent shall cause the Lucent

Transferred  Individuals  under the AT&T Health and Welfare Plans and apply such
elections  under the Lucent  Health and Welfare  Plans for the  remainder of the
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
the Close of the Distribution Date shall neither  constitute nor be treated as a
"status change" under the AT&T Health and Welfare Plans or the Lucent Health and
Welfare Plans.






                           (ii) Lucent shall cause the Lucent
Health and Welfare

out-of-pocket  maximums,  and other  applicable  benefit  coverage  limits  with
respect to which such  expenses have been  incurred by  Transferred  Individuals
under the AT&T Health and Welfare  Plans for the  remainder of the year in which
the Distribution  occurs,  and (B) all benefits paid to Transferred  Individuals
under the AT&T Health and Welfare  Plans for purposes of  determining  when such
persons have reached their lifetime maximum benefits under the Lucent Health and
Welfare Plans.

                           (iii) Lucent shall recognize and
maintain through
December  31,  1998 all  eligible  populations  covered  by the AT&T  Health and
Welfare  Plans (as  defined  in the  applicable  AT&T  Health and  Welfare  Plan
documents),  including  Class I and  Class II  dependents,  term  and  temporary

                           (iv) Lucent shall (A) provide coverage
to Transferred
Individuals  under the Lucent Group Life  Program  without the need to undergo a
physical  examination or otherwise  provide  evidence of  insurability,  and (B)
recognize  and maintain all  irrevocable  assignments  and  accelerated  benefit
option  elections  made by  Transferred  Individuals  under the AT&T  Group Life
Program.


                  (b)  ADMINISTRATION.

                           (i) COORDINATION OF BENEFITS FOR
SPOUSES AND
DEPENDENTS.  Effective  as of the first  January  1 that  occurs on or after the
Distribution  Date,  Lucent shall cause the Lucent  Health and Welfare  Plans to
permit  eligible  Transferred  Individuals  to cover  their  lawful  spouses  as
dependents if such lawful  spouses are active or retired AT&T  employees.  As of
the first January 1 that occurs on or after the  Distribution  Date,  AT&T shall
cause the AT&T Health and Welfare Plans to permit  eligible AT&T and AT&T Entity
employees to cover their lawful spouses as dependents if such lawful spouses are
active or retired  Lucent  employees.  All  benefits  provided  under either the
Lucent Health and Welfare Plans or the AT&T Health and Welfare Plans to a lawful
spouse  dependent of the other company's plans shall be coordinated  pursuant to
the terms and conditions of the applicable  Health and Welfare Plans.  Effective
as of January 1, 1997,  eligible  dependents  of AT&T and Lucent  lawful  spouse
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
reports that relate to Transferred Individuals.  Lucent and AT&T shall share all
information  necessary to verify HCFA data match reports  regarding  Transferred
Individuals.  Lucent  shall  not  change  any  employee  identification  numbers
assigned  by AT&T  without  notifying  AT&T of the change  and the new  Employee
Identification  Number.  To the  extent  that AT&T  enters  into any  settlement
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.

Transferred  Individual.  If Lucent recovers any amounts through  subrogation or
otherwise for claims incurred by or reimbursed to employees and former employees

HPSS data  during  the period  from the first  January 1 that  occurs  after the
Distribution  Date through December 31, 1998, and share all such data. Both AT&T
and Lucent shall have the right to access and use eligibility,  incurred claims,
and HPSS data for periods  through  December 31, 1998 for such  purposes as each
determines.

         5.22 APPLICATION OF ARTICLE V TO LUCENT ENTITIES. Any

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
the  Distribution  Date  under an AT&T  Health and  Welfare  Plan and which were
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.


                                   ARTICLE VI
              EXECUTIVE BENEFITS AND NON-EMPLOYEE DIRECTOR BENEFITS

         6.1  ASSUMPTION  OF  OBLIGATIONS.   Effective   Immediately  after  the
Distribution  Date,  Lucent and the Lucent  Entities  shall assume and be solely
responsible for all Liabilities to or relating to Transferred  Individuals under

         6.2  CONSENTS  AND  NOTIFICATIONS.  AT&T and  Lucent  shall  use  their
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,
and of each  Lucent  Non-Employee  Director  who is a  participant  in any  AT&T
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

interpreted  by Lucent,  in its sole  discretion,  after taking into account the
effects of the IPO and the Distribution) have been met and (b) the payment level
for each Transferred Individual.

         6.4 AT&T LONG TERM  INCENTIVE  PLANS.  AT&T and Lucent  shall use their
reasonable  best efforts to take all actions  necessary or  appropriate  so that
each  outstanding  Award granted under any AT&T Long Term Incentive Plan held by
any  Transferred  Individual  shall be replaced as set forth in this Section 6.4
with an Award under the Lucent Long Term Incentive Plan.







                  (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






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






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







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






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

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

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

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

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

                  (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






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






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





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






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.







         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

                  (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

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

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

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





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
bargaining,  AT&T  or  Lucent  may  be  obligated  to  bargain  with  the  union
representing  affected employees  concerning those subjects.  Neither party will
agree to a  modification  of the  Collective  Bargaining  Agreement  without the
consent  of the  other.  In the event a force  surplus  affecting  members  of a
bargaining  unit in both AT&T or any AT&T Entity (on the one hand) and Lucent or
any Lucent Entity (on the other hand) directly results, due to the provisions of
the Collective Bargaining Agreement, in an






employee  involuntarily  leaving  the  payroll  of the party not  declaring  the
surplus,  then  the  party  declaring  the  surplus  shall  bear the cost of any
severance payable to such employee.

         8.13 CONSENT OF THIRD  PARTIES.  If any provision of this  Agreement is
dependent  on the  consent of any third  party (such as a vendor or a union) and
such  consent is  withheld,  AT&T and  Lucent  shall use their  reasonable  best
efforts to implement the  applicable  provisions  of this  Agreement to the full
extent practicable. If any provision of this Agreement cannot be implemented due
to the failure of such third party to consent,  AT&T and Lucent shall  negotiate
in good faith to implement the provision in a mutually  satisfactory manner. The
phrase  "reasonable  best  efforts" as used  herein  shall not be  construed  to
require the incurrence of any non-routine or  unreasonable  expense or liability
or the waiver of any right.

         8.14 POST-DISTRIBUTION  BENEFIT
DELIVERY/ADMINISTRATION.  Lucent shall
continue to use the P2000 benefit administration system and a compatible pension
payment  system,  to administer  the Lucent Pension Plans through the end of the
Management Transition Period.

         8.15 QUIET  PERIODS.  Lucent  shall take such action as is necessary to
ensure that participants in the Lucent LTSSP, the Lucent LTSPME,  and the Lucent
RSPSP are notified that a quiet period will occur  beginning on or about October
1,  1996,  during  which  changes  in  investment   direction  with  respect  to
participants' accounts generally will not be permitted.

or construed by the parties or any third party as creating the  relationship  of

understood  and agreed that no  provision  contained  herein,  and no act of the
