or among Avaya and/or any member of the Avaya Group, on the one hand, and Lucent

cause to be taken, such other actions as may be necessary to effect the
foregoing.

                  (b) The provisions of Section 2.4(a) shall not apply to any of
the following agreements, arrangements, commitments or understandings (or to any
of the provisions thereof): (i) this Agreement and the Ancillary Agreements (and
each other agreement or instrument expressly contemplated by this Agreement or

Groups under any such agreements, arrangements, commitments or understandings
constitute Avaya Assets or Avaya Liabilities, they shall be assigned pursuant to
Section 2.1); (iv) any intercompany accounts payable or accounts receivable
accrued as of the Distribution Date that are reflected in the books and records
of the parties or otherwise documented in writing in accordance with past
practices; (v) any agreements, arrangements, commitments or understandings to

interests will be disregarded for purposes of determining whether a Subsidiary
is wholly owned); (vi) any written Tax sharing or Tax allocation agreements to

to the Crossover Agreements. The parties intend that Lucent and/or Avaya, as the

Agreements and to provide products, software or services related to their
respective businesses pursuant to the Crossover Agreements on the terms and
conditions set forth in any such Crossover Agreement for the entire unexpired
initial term thereof, including any renewal options that may be unilaterally
exercised by the customer (but not for any other term of renewal). The prices

         2.5. Documents Relating to Transfer of Real Property Interests and
Tangible Property Located Thereon

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

                  (b) Except as otherwise expressly provided in this Agreement
or any Ancillary Agreement, all tenant improvements, fixtures, furniture, office
equipment, servers, private branch exchanges, artwork and other tangible
property (other than equipment subject to capital or operating equipment leases,
which will be transferred or retained based on whether the associated capital or
operating equipment lease is or is not an Avaya Contract) located as of the date
hereof on any real property that is covered by any Ancillary Agreement referred
to in Section 2.5(a), including the Schedules thereto, shall, except to the
extent expressly set forth on a Schedule referred to in Section 2.5(a), be
transferred or retained as follows:

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

                           (ii) SHARED FACILITIES THAT ARE OWNED. In the case of
any real property or leasehold interests covered by an Ancillary Agreement set
forth on Schedule 2.5 that is a lease, all such tangible property will be
retained by the lessor under the applicable lease, except that any such tangible
property (other than tenant improvements, fixtures, furniture and artwork) used
exclusively by the lessee shall be transferred to, or retained by, the lessee.

                           (iii) SHARED DOMESTIC FACILITIES WITH THIRD PARTY
LEASES. In the case of any real property or leasehold interests located in the
United States covered by an Ancillary Agreement set forth on Schedule 2.5 that
is a sublease or sub-sublease, all such tangible property will be retained by
the sublessor or sub-sublessor, respectively, under the applicable sublease or


                                      -19-
<PAGE>   25
sub-sublease, except that any such tangible property (other than tenant
improvements, fixtures and artwork), including furniture used exclusively by the
sublessee or sub-sublessee, respectively, shall be transferred to, or retained
by, such sublessee or sub-sublessee.

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

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

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

         2.6. Documents Relating to Other Transfers of Assets and Assumption of
Liabilities

                  In furtherance of the contribution, assignment, transfer and
conveyance of Avaya Assets and the acceptance and assumption of Avaya
Liabilities set forth in Section 2.1(a) and (b) simultaneously with the
execution and delivery hereof or as promptly as practicable thereafter, (i)
Lucent shall execute and deliver, and shall cause its Subsidiaries to execute
and deliver, such bills of sale, stock powers, certificates of title,
assignments of Contracts and other instruments of transfer, conveyance and
assignment as and to the extent necessary to evidence the transfer, conveyance
and assignment of all of Lucent's and its Subsidiaries' right, title and
interest in and to the Avaya Assets to Avaya and (ii) Avaya shall execute and
deliver, to Lucent and its Subsidiaries such bills of sale, stock powers,
certificates of title, assumptions of contracts and other instruments of
assumption as and to the extent necessary to evidence the valid and effective
assumption of the Avaya Liabilities by Avaya.

         2.7. Ancillary Agreements

                  (a) On the date hereof, but effective as of the date

                                      -20-
<PAGE>   26
                  (b) Effective on the date hereof, the parties shall execute
and deliver each of the following Ancillary Agreements to which it is a party:

                           (i) the Patent Assignment;

                           (ii) the Technology Assignment and Joint Ownership
Agreement;

                           (iii) the Trade Dress Assignment; and

                           (iv) the Trademark and Service Mark Assignment.

         2.8. The Non-U.S. Plan

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

         2.9. Disclaimer of Representations and Warranties

                  (a) Each of Lucent (on behalf of itself and each member of the
Lucent Group), and Avaya (on behalf of itself and each member of the Avaya
Group) understands and agrees that, except as expressly set forth herein
(including in Section 7.2(g)) or in any Ancillary Agreement, no party to this
Agreement, any Ancillary Agreement or any other agreement or document
contemplated by this Agreement, any Ancillary Agreement or otherwise, is
representing or warranting in any way as to the Assets, businesses or
Liabilities transferred or assumed as contemplated hereby or thereby, as to any
consents or approvals required in connection therewith, as to the value or
freedom from any Security Interests of, or any other matter concerning, any
Assets of such party, or as to the absence of any defenses or right of setoff or
freedom from counterclaim with respect to any claim or other Asset, including
any accounts receivable, of any party, or as to the legal sufficiency of any
assignment, document or instrument delivered hereunder to convey title to any
Asset or thing of value upon the execution, delivery and filing hereof or
thereof. Except as may expressly be set forth herein or in any Ancillary
Agreement, all such Assets are being transferred on an "as is," "where is" basis
(and, in the case of any real property, by means of a quitclaim or similar form
deed or conveyance) and the respective transferees shall bear the economic and
legal risks that (i) any conveyance shall prove to be insufficient to vest in
the transferee good and marketable title, free and clear of any Security
Interest, and (ii) any necessary consents or approvals are not obtained or that
any requirements of laws or judgments are not complied with.

         2.10. Financing Arrangements

                  Prior to the Distribution Date, Lucent and Avaya entered into
the Financing Facility. Lucent and Avaya agree to take all such reasonable
action as may be necessary to


                                      -21-
<PAGE>   27
assure the assignment to and the assumption by Avaya of all obligations
thereunder and the full release and discharge of each of Lucent and any other
member of the Lucent Group of all of its obligations thereunder as of the
Distribution Date in accordance with the terms of the Financing Facility. Lucent
and Avaya shall participate in the preparation of all materials as may be
reasonably necessary to obtain such assignment, assumption, release and
discharge. As of the time of such assignment, assumption, release and discharge,
Lucent shall pay all third party costs and expenses incurred by any member of
the Lucent Group associated with the Financing Facility.

         2.11. Governmental Approvals and Consents

                  (a) To the extent that the Contribution requires any
Governmental Approvals or Consents, the parties will use their reasonable best
efforts to obtain any such Governmental Approvals and Consents.

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

                  (c) If the transfer or assignment of any Assets intended to be
transferred or assigned hereunder including pursuant to the Non-U.S. Plan, is
not consummated prior to or at the Distribution Date, whether as a result of the
provisions of Section 2.11(b) or for any other reason, then the Person retaining
such Asset shall thereafter hold such Asset for the use and benefit insofar as
reasonably possible, of the Person entitled thereto (at the expense of the
Person entitled thereto). In addition, the Person retaining such Asset shall
take such other actions as may be reasonably requested by the Person to whom
such Asset is to be transferred in order to place such Person, insofar as
reasonably possible, in the same position as if such Asset had been transferred
as contemplated hereby and so that all the benefits and burdens relating to such
Avaya Assets (or such Non-Avaya Assets, as the case may be), including
possession, use, risk of loss, potential for gain, and dominion, control and
command over such Assets, are to inure from and after the Distribution Date to
the Avaya Group (or the Lucent Group, as the case may be).

                  (d) If and when the Consents and/or Governmental Approvals,
the absence of which caused the deferral of transfer of any Asset pursuant to
Section 2.11(b), are obtained, the transfer of the applicable Asset shall be
effected in accordance with the terms of this Agreement and/or the applicable
Ancillary Agreement.


                                      -22-
<PAGE>   28
                  (e) The Person retaining an Asset due to the deferral of the
transfer of such Asset shall not be obligated, in connection with the foregoing,
to expend any money unless the necessary funds are advanced by the Person
entitled to the Asset, other than reasonable out-of-pocket expenses, attorneys'
fees and recording or similar fees, all of which shall be promptly reimbursed by
the Person entitled to such Asset.

         2.12. Novation of Assumed Avaya Liabilities

                  (a) Each of Lucent and Avaya, at the request of the other,
shall use its reasonable best efforts to obtain, or to cause to be obtained, any
consent, substitution, approval or amendment required to novate (including with
respect to any federal government contract) or assign all obligations under
agreements, leases, licenses and other obligations or Liabilities (including
Avaya OFL's) of any nature whatsoever that constitute Avaya Liabilities, or to
obtain in writing the unconditional release of all parties to such arrangements
other than any member of the Avaya Group, so that, in any such case, Avaya and
its Subsidiaries will be solely responsible for such Liabilities; provided,
however, that none of Lucent or Avaya shall be obligated to pay any
consideration therefor to any third party from whom such consents, approvals,
substitutions and amendments are requested. Lucent and Avaya agree to enter into
a novation agreement with the United States Government providing for the
assignment of prime Government contracts that are Avaya Contracts from Lucent to
Avaya substantially in the form of the novation agreement prescribed by the
Federal Acquisition Regulation (FAR) or upon such terms as may be reasonably
requested by the Government and to provide the documents prescribed by the FAR
to be filed with such novation request.

                  (b) If Lucent or Avaya is unable to obtain, or to cause to be
obtained, any such required consent, approval, release, substitution or
amendment, the applicable member of the Lucent Group shall continue to be bound
by such agreements, leases, licenses and other obligations and, unless not
permitted by law or the terms thereof (except to the extent expressly set forth
in Section 7.2 in the case of Avaya OFL's), Avaya shall, as agent or
subcontractor for Lucent or such other Person and where appropriate in the name
thereof, as the case may be, pay, perform and discharge fully all the
obligations or other Liabilities of Lucent or such other Person, as the case may
be, thereunder from and after the date hereof. Avaya shall indemnify each Lucent
Indemnitee and hold each of them harmless against any Liabilities arising in
connection therewith. Except as expressly set forth in Section 7.2 in the case
of Avaya OFL's, Lucent shall, without further consideration, pay and remit, or
cause to be paid or remitted to Avaya promptly all money, rights and other
consideration received by it or any member of its Group in respect of such
performance (unless any such consideration is an Excluded Asset). If and when
any such consent, approval, release, substitution or amendment shall be obtained
or such agreement, lease, license or other rights or obligations shall otherwise
become assignable or able to be novated, Lucent shall thereafter assign, or
cause to be assigned, all its rights, obligations and other Liabilities
thereunder or any rights or obligations of any member of its Group to Avaya
without payment of further consideration and Avaya shall, without the payment of
any further consideration, assume such rights and obligations.

         2.13. Novation of Liabilities other than Avaya Liabilities


                                      -23-
<PAGE>   29
                  (a) Each of Lucent and Avaya, at the request of the other,
shall use its reasonable best efforts to obtain, or to cause to be obtained, any
consent, substitution, approval or amendment required to novate or assign all
obligations under agreements, leases, licenses and other obligations or
Liabilities of any nature whatsoever that do not constitute Avaya Liabilities,
or to obtain in writing the unconditional release of all parties to such
arrangements other than any member of the Lucent Group, so that, in any such
case, the members of the Lucent Group will be solely responsible for such
Liabilities; provided, however, that neither Lucent nor Avaya shall be obligated
to pay any consideration therefor to any third party from whom such consents,
approvals, substitutions and amendments are requested.

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

         2.14. Third Party Intellectual Property License Agreements

                  (a) Effective as of the date hereof, Lucent hereby assigns to
Avaya the intellectual property license agreements listed on Schedule 2.14(a).
Except for the intellectual property license agreements listed on Schedule

among other things, the Distribution will qualify as a tax-free distribution for
federal income tax purposes under Section 355 of the Code and the transfer to
Avaya of the Avaya Assets and the assumption by Avaya of the Avaya Liabilities
in connection with the Contribution will not result in the recognition of any
gain or loss to Lucent, Avaya or Lucent's or Avaya's stockholders for federal
income tax purposes, and such ruling shall be in form and substance satisfactory
to Lucent in its sole discretion.

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

                   (d) No other events or developments shall have occurred
subsequent to the date hereof that, in the judgment of the Lucent Board of
Directors, would result in the Distribution having a material adverse effect on
Lucent or on the stockholders of Lucent.

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

owner of Lucent Common Stock as of the Record Date, to aggregate all such
fractional shares and sell the whole shares obtained thereby at the direction of
Lucent either to Lucent, in open market transactions or otherwise, in each case
at then prevailing trading prices, and to cause to be distributed to each such
holder or for the benefit of each such beneficial owner, in lieu of any
fractional share, such holder's or owner's ratable share of the proceeds of such
sale, after making appropriate deductions of the amount required to be withheld
for federal income tax purposes and after deducting an amount equal to all
brokerage charges, commissions and transfer taxes attributed to such sale.

                                      -31-
<PAGE>   37
Lucent Indemnitees relating to, arising out of or resulting from any of the
following items (without duplication):

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

                  (b) the Avaya Business, any Avaya Liability or any Avaya
Contract;

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

                  (d) (i) termination pay, (ii) severance cost or expense or
(iii) other direct cost or expense, in each case related to, or otherwise
arising from, Lucent's providing Avaya with interim services related to accounts
payable, accounts receivable and payroll processing pursuant to the Interim
Services and Systems Replication Agreement; and

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

         5.3.     Indemnification by Lucent

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

                  (a) the failure of Lucent or any other member of the Lucent
Group or any other Person to pay, perform or otherwise promptly discharge any
Liabilities of the Lucent Group other than the Avaya Liabilities whether prior
to or after the date hereof;

                  (b) the Lucent Business or any Liability of the Lucent Group
other than the Avaya Liabilities; and

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

         5.4. Indemnification Obligations Net of Insurance Proceeds and Other
Amounts

                  (a) The parties intend that any Liability subject to
indemnification or reimbursement pursuant to this Article V or Article VI will
be net of Insurance Proceeds that actually reduce the amount of the Liability.
Accordingly, the amount which any party (an "Indemnifying Party") is required to
pay to any Person entitled to indemnification hereunder (an


                                      -32-
<PAGE>   38
"Indemnitee") will be reduced by any Insurance Proceeds theretofore actually
recovered by or on behalf of the Indemnitee in reduction of the related
Liability. If an Indemnitee receives a payment (an "Indemnity Payment") required
by this Agreement from an Indemnifying Party in respect of any Liability and
subsequently receives Insurance Proceeds, then the Indemnitee will pay to the
Indemnifying Party an amount equal to the excess of the Indemnity Payment
received over the amount of the Indemnity Payment that would have been due if
the Insurance Proceeds had been received, realized or recovered before the
Indemnity Payment was made.

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

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

         5.5.     Procedures for Indemnification of Third Party Claims

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

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


                                      -33-

following any notice given by the Indemnitee to the Indemnifying Party. Unless
the parties have acknowledged that the applicable Third Party Claim (including
any Third Party Claim set forth on Schedule 6.6) is not a Shared Contingent
Liability or unless a determination to such effect has been made in accordance
with Section 6.6, Lucent shall be entitled (but not obligated) to assume the
defense of such Third Party Claim as if it were the Indemnifying Party
hereunder. In any such event, Lucent shall be entitled to reimbursement of all
the costs and expenses of such defense once a final determination or
acknowledgment is made as to the status of the Third Party Claim; provided that,
if such Third Party Claim is determined to be a Shared Contingent Liability,
such costs and expenses shall be shared as provided in Section 5.5(c).

                  (c) Lucent shall assume the defense of, and may, subject to
Section 5.5(g), seek to settle or compromise, any Third Party Claim that is a
Shared Contingent Liability, and the costs and expenses thereof shall be
included in the calculation of the amount of the applicable Shared Contingent
Liability in determining the reimbursement obligations of the other parties with
respect thereto pursuant to Section 6.4. Any Indemnitee in respect of a Shared
Contingent Liability shall have the right to employ separate counsel and to
participate in (but not control) the defense, compromise, or settlement thereof,
but all fees and expenses of such counsel shall be the expense of such
Indemnitee.

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

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

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

<PAGE>   40
                  (g) In the case of a Third Party Claim that is not a Shared
Contingent Liability, no Indemnifying Party shall consent to entry of any
judgment or enter into any settlement of the Third Party Claim without the
consent of the Indemnitee if the effect thereof is to permit any injunction,
declaratory judgment, other order or other nonmonetary relief to be entered,
directly or indirectly against any Indemnitee. In the case of a Third Party
Claim that is a Shared Contingent Liability, Lucent shall not consent to entry
of any judgment or enter into any settlement of the Third Party Claim without
the consent of the Indemnitee if the effect thereof is to permit any injunction,
declaratory judgment, other order or other nonmonetary relief to be entered,
directly or indirectly, against any Indemnitee.

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

         5.6.     Additional Matters

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

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

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

         5.7.     Remedies Cumulative

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

         5.8.     Survival of Indemnities

                  The rights and obligations of each of Lucent and Avaya and
their respective Indemnitees under this Article V shall survive the sale or
other transfer by any party of any Assets or businesses or the assignment by it
of any Liabilities.

         5.9.     Alleged Infringement or Misappropriation

                  (a) The provisions of this Section 5.9 shall apply
notwithstanding any other provisions of this Agreement or any Ancillary
Agreement. The provisions of this Section 5.9 shall apply in the event of any
claim, action, proceeding or suit by a third party alleging an infringement of
any patent, copyright, trademark or misappropriation of a trade secret against
(i) Lucent or any member of the Lucent Group with respect to any product,
software or other material provided by or ordered from the Avaya Business, or
(ii) Avaya or any member of the Avaya Group with respect to any product,
software or other material provided by or ordered from the Lucent Business, in
each case prior to the Distribution Date. In each case, Lucent, such member of
the Lucent Group, Avaya or such member of the Avaya Group is referred to as the
"IP Indemnified Party," and Lucent (in the case where Avaya or a member of the
Avaya Group is the IP Indemnified Party) or Avaya (in the case where Lucent or a
member of the Lucent Group is the Indemnified Party) shall be referred to as the
"IP Indemnifying Party." In any such claim, action, proceeding or suit, the IP
Indemnifying Party, at its expense, will defend the IP Indemnified Party,
subject to the conditions and exceptions stated below. The IP Indemnifying Party
will reimburse the IP Indemnified Party for any cost, expense or attorneys'
fees, incurred at the IP Indemnifying Party's written request or authorization,
and will indemnify the IP Indemnified Party against any liability assessed
against the IP Indemnified Party by final judgment on account of such
infringement or misappropriation arising out of such use.

                  (b) If the IP Indemnified Party's use shall be enjoined or in
the IP Indemnified Party's opinion is likely to be enjoined, the IP Indemnifying
Party will, at its expense and at its option, either (i) replace the enjoined
product, software or other material furnished as described in Section 5.9(a)
with a suitable substitute free of any infringement; (ii) modify it so that it
will be free of the infringement; or (iii) procure for the IP Indemnified Party
a license or other right to use it. If none of the foregoing options are
practical despite the IP Indemnifying Party's commercially reasonable efforts,
then the IP Indemnifying Party will remove the enjoined product, software or
other material and refund to the IP Indemnified Party any amounts paid to the IP
Indemnifying Party therefor less a reasonable charge for any actual period of
use by the IP Indemnified Party.

                  (c) The IP Indemnified Party shall give the IP Indemnifying
Party prompt written


                                      -36-
<PAGE>   42
notice of all such claims, actions, proceedings or suits alleging infringement
or violation and the IP Indemnifying Party shall have full and complete
authority to assume the sole defense thereof, including appeals, and to settle
same; provided, however, the IP Indemnifying Party shall not consent to entry of
any judgment or enter into any settlement without the consent of the IP
Indemnified Party if the effect thereof is to permit any injunction, declaratory
judgment, other order or other nonmonetary relief to be entered, directly or
indirectly, against the IP Indemnified Party. The IP Indemnified Party shall,
upon the IP Indemnifying Party's request and at the IP Indemnifying Party's
expense, furnish all information and assistance available to the IP Indemnified
Party and cooperate in every reasonable way to facilitate the defense and/or
settlement of any such claim, action, proceeding or suit.

                  (d) No undertaking of the IP Indemnifying Party under this
Section 5.9 shall extend to any such alleged infringement or violation to the
extent that it: (i) arises from adherence to design modifications,
specifications, drawings, or written instructions which the IP Indemnifying
Party was directed by the IP Indemnified Party to follow, but only if such
alleged infringement or violation does not reside in corresponding commercial
product, software or other material of the IP Indemnifying Party's design or
selection; or (ii) arises from adherence to instructions to apply the IP
Indemnified Party's trademark, trade name or other company identification; or
(iii) resides in a product, software or other material which are not of the IP
Indemnifying Party's origin and which are furnished by the IP Indemnified Party
to the IP Indemnifying Party for use as described in Section 5.9(a); or (iv)
relates to uses of product, software or other material provided by the IP
Indemnifying Party in combinations with other product, software or other
material, furnished either by the IP Indemnifying Party or others, which
combination was not installed, recommended or otherwise approved by the IP
Indemnifying Party. In the foregoing cases numbered (i) through (iv), the IP
Indemnified Party will defend and save the IP Indemnifying Party harmless,
subject to the same terms and conditions and exceptions stated above, with
respect to the IP Indemnifying Party's rights and obligations under this
section.

                  (e) The liability and rights of the IP Indemnifying Party and
the IP Indemnified Party with respect to any and all claims, actions,
proceedings or suits by third parties alleging infringement of patents,
trademarks or copyrights or violation of trade secrets or proprietary rights
because of, or in connection with, any product, software or other material
furnished as described in Section 5.9(a) shall be limited to the specific
undertakings contained in this Section 5.9.


                                   ARTICLE VI
                   CONTINGENT GAINS AND CONTINGENT LIABILITIES

         6.1. Definitions Relating to Contingent Gains and Contingent
Liabilities

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


                                      -37-
<PAGE>   43
                  (a) CONTINGENT CLAIM COMMITTEE means a committee composed of
one representative designated from time to time by each of Lucent and Avaya that
shall be established in accordance with Section 6.6.

                  (b) CONTINGENT GAIN means any claim or other right of Lucent,
Avaya or any of their respective Affiliates, whenever arising, against any
Person other than Lucent, Avaya or any of their respective Affiliates, if and to
the extent that (i) such claim or right has accrued as of the Distribution Date
(based on then existing law) and (ii) the existence or scope of the obligation
of such other Person as of the Distribution Date was not acknowledged, fixed or
determined in any material respect, due to a dispute or other uncertainty as of
the Distribution Date or as a result of the failure of such claim or other right
to have been discovered or asserted as of the Distribution Date. A claim or
right meeting the foregoing definition shall be considered a Contingent Gain
regardless of whether there was any Action pending, threatened or contemplated
as of the Distribution Date with respect thereto. For purposes of the foregoing,
a claim or right shall be deemed to have accrued as of the Distribution Date if
all the elements of the claim necessary for its assertion shall have occurred on
or prior to the Distribution Date, such that the claim or right, were it
asserted in an Action on or prior to the Distribution Date, would not be
dismissed by a court on ripeness or similar grounds. Notwithstanding the
foregoing, none of (i) any Insurance Proceeds, (ii) any Excluded Assets, (iii)
any reversal of any litigation or other reserve, or (iv) any matters relating to
Taxes (which are governed by the Tax Sharing Agreement) shall be deemed to be a
Contingent Gain.

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


                                      -38-
<PAGE>   44
                  (d) EXCESS PORTION means that portion, if any, of the
aggregate Value of all amounts actually paid by Lucent or Avaya (in each case,
together with any members of its respective Group), in respect of any single
Exclusive Contingent Liability of such Group or any Related Exclusive Contingent
Liabilities of such Group that is in excess of $50 million.

                  (e) EXCLUSIVE CONTINGENT LIABILITY means any Exclusive Lucent
Contingent Liability or Exclusive Avaya Contingent Liability.

                  (f) EXCLUSIVE AVAYA CONTINGENT GAIN means any Contingent Gain
if such Contingent Gain primarily relates to any Avaya Business (including any
Avaya Business included in the definition of an Exclusive Lucent Contingent Gain
within the meaning of the SDA Agreement), including the matters listed or
described on Schedule 6.1(f) hereto, or if such Contingent Gain is expressly
assigned to Avaya pursuant to this Agreement or any Ancillary Agreement.

                  (g) EXCLUSIVE LUCENT CONTINGENT GAIN means any Contingent Gain
if such Contingent Gain primarily relates to any Lucent Business(including any
Lucent Business included in the definition of an Exclusive Lucent Contingent
Gain within the meaning of the SDA Agreement), including the matters listed or
described on Schedule 6.1(g) hereto, or if such Contingent Gain is expressly
assigned to Lucent pursuant to this Agreement or any Ancillary Agreement.

                  (h) EXCLUSIVE AVAYA CONTINGENT LIABILITY means any Contingent
Liability if such Contingent Liability primarily relates to any Avaya Business
(including any Avaya Business included in the definition of an Exclusive Lucent
Contingent Liability within the meaning of the SDA Agreement) , including the
matters listed or described on Schedule 6.1(f) hereto, or if such Contingent
Liability is expressly assigned to Avaya pursuant to this Agreement or any
Ancillary Agreement.

                  (i) EXCLUSIVE LUCENT CONTINGENT LIABILITY means any Contingent
Liability if such Contingent Liability primarily relates to any Lucent Business
(including any Lucent Business included in the definition of an Exclusive Lucent
Contingent Liability within the meaning of the SDA Agreement) including the
matters listed or described on Schedule 6.1(g) hereto, or if such Contingent
Liability is expressly assigned to Lucent pursuant to this Agreement or any
Ancillary Agreement.

                  (j) RELATED EXCLUSIVE CONTINGENT LIABILITIES of any Group
means:

                           (i) in the case of any Exclusive Contingent
Liabilities of such Group other than Environmental Liabilities, any set or group
of Exclusive Contingent Liabilities of such Group (but not including any
Exclusive Contingent Liabilities of any other Group) arising from:

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


                                      -39-
<PAGE>   45
                                    (B) any Action that is brought or threatened
to be brought as a class action and that is settled; and

                           (ii) in the case of any Exclusive Contingent
Liabilities of such Group that are Environmental Liabilities:

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

                                    (B) any and all Environmental Liabilities of
such Group arising from separate sites but listed on the National Priorities
List as a single site. Exclusive Contingent Liabilities of such Group that are
Environmental Liabilities of such Group arising from sites listed separately on
the National Priorities List shall not be deemed to be Related Exclusive
Contingent Liabilities. Whether sites not listed on the National Priorities List
shall be deemed to be a "single site" for purposes of clause (B) of this
definition shall be determined by applying the definition of "on-site" contained
in 40 C.F.R. Section 300.5 (as in effect an as of the date of this Agreement)
which provides that "On-site means the areal extent of contamination and all
suitable areas in very close proximity to the contamination necessary for
implementation of the response action." Site identifications by a state or local
Governmental Authority similar in import to those authorized by the definition
of "on-site" in 40 C.F.R. Section 300.5 (as in effect as of the date of this
Agreement) shall similarly be determinative of whether sites not listed on the
National Priorities List shall be deemed to be a "single site" for purposes of
this definition.

                  (k) SHARED CONTINGENT GAIN means any Contingent Gain that is
not an Exclusive Lucent Contingent Gain or an Exclusive Avaya Contingent Gain
including any Contingent Gain relating to, arising out of or resulting from the
matters set forth on Schedule 6.1(k).

                  (l) SHARED CONTINGENT LIABILITY means, without duplication:

                           (i) any Contingent Liability that is not an Exclusive
Lucent Contingent Liability or an Exclusive Avaya Contingent Liability;

                           (ii) any Liability (other than Taxes) relating to,
arising out of or resulting from any Other Discontinued Operations;

                           (iii) any Liability (other than Taxes) relating to,
arising out of or resulting from the matters set forth on Schedule 6.1(l); and

                           (iv) any Shared Contingent Liability within the
meaning of the SDA Agreement.

                  (m) SHARED AVAYA PERCENTAGE means [90]%.

                  (n) SHARED LUCENT PERCENTAGE means [10]%.

                  (o) SHARED PERCENTAGE means the Shared Lucent Percentage or
the Shared Avaya Percentage, as the case may be.

                  (p) VALUE means the aggregate amount of all cash payments, the
fair market value of all non-cash payments and the incremental cost of providing
any goods or services made or provided in respect of any Exclusive Contingent
Liability or Related Exclusive Contingent Liabilities, whether in satisfaction
of any judgment, in settlement of any Action or threatened Action or otherwise
(including all costs and expenses of defending or investigating any Action or
threatened Action), net of: (i) any Insurance Proceeds received or realized in
respect of the applicable Exclusive Contingent Liability or Related Exclusive
Contingent Liabilities (applied in reduction of the applicable Liability in the
manner contemplated by Section 5.4), (ii) any Tax benefits associated with such
payments or the provision of such goods or services (based on assumed effective
Tax rate equal to the effective Tax rate of the applicable party for the fiscal
year immediately preceding the year in which such payments are made or goods or
services provided (it being understood that the effective Tax rate for any party
whose earnings for such immediately preceding fiscal year are consolidated for
federal income tax purposes with another corporation shall be the effective Tax
rate of the corporation filing such federal income tax return for such
immediately preceding fiscal year)), (iii) any other amounts recovered
(including by way of set off) from a third party in connection with any such
Action or threatened Action and (iv) the amount of any reserve, account payable
or similar accrual in respect of the Exclusive Contingent Liability or Related
Exclusive Contingent Liabilities, net of any offsetting receivables in respect
of such Exclusive Contingent Liability or Related Exclusive Contingent
Liabilities, in each case as reflected on the Avaya Balance Sheet or the audited
consolidated balance sheet of Lucent, including the notes thereto, as of

         6.2.     Contingent Gains

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

                  (b) Any benefit that may be received from any Shared
Contingent Gain shall be shared among Lucent and Avaya in proportion to the
Shared Lucent Percentage and the Shared Avaya Percentage, respectively, and
shall be paid in accordance with Section 6.5. Notwithstanding the foregoing,
Lucent shall have sole and exclusive authority to commence, prosecute, settle,
manage, control, conduct, waive, forgo, release, discharge, forgive and
otherwise determine all matters whatsoever with respect to any Shared Contingent
Gain. Avaya shall not take, or permit any member of its Group to take, any
action (including commencing any claim) that would interfere with such rights
and powers of Lucent. Lucent shall use its reasonable efforts to notify Avaya in
the event that it commences an Action with respect to a Shared Contingent Gain;
provided that the failure to provide such notice shall not give rise to any


                                      -41-
<PAGE>   47
rights on the part of Avaya against Lucent or affect any other provision of this
Section 6.2. Avaya acknowledges that Lucent may elect not to pursue any Shared
Contingent Gain for any reason whatsoever (including a different assessment of
the merits of any Action, claim or right than Avaya or any business reasons that
are in the best interests of Lucent or a member of the Lucent Group, without
regard to the best interests of any member of the Avaya Group) and that no
member of the Lucent Group shall have any liability to any Person (including any
member of the Avaya Group) as a result of any such determination.

                  (c) In the event of any dispute as to whether any claim or
right is a Contingent Gain or whether any Contingent Gain is a Shared Contingent
Gain, an Exclusive Lucent Contingent Gain or an Exclusive Avaya Contingent Gain,
Lucent may, but shall not be obligated to, commence prosecution or other
assertion of such claim or right pending resolution of such dispute. In the
event that Lucent commences any such prosecution or assertion and, upon
resolution of the dispute, it is determined hereunder that Avaya has the
exclusive right to such claim or right, Lucent shall, promptly upon the request
of Avaya, discontinue the prosecution or assertion of such right or claim and
transfer the control thereof to Avaya. In such event, Avaya will reimburse
Lucent for all costs and expenses, reasonably incurred prior to resolution of
such dispute in the prosecution or assertion of such claim or right.

         6.3.     Exclusive Contingent Liabilities

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

                  (b) Notwithstanding anything to the contrary in this
Agreement, if the aggregate Value of all amounts paid by Lucent or Avaya (in
each case, together with any members of its respective Group) in respect of any
single Exclusive Contingent Liability of such Group or any Related Exclusive
Contingent Liabilities of such Group is in excess of $50 million, each of Lucent
or Avaya, as the case may be, shall be entitled to reimbursement from each of
the others for a share of the Excess Portion in accordance with the following
percentages:

                           (i) in the case of Exclusive Lucent Contingent
Liabilities, Lucent shall bear [90]% of such Excess Portion and Avaya shall bear
[10]% of such Excess Portion; and

                           (ii) in the case of Exclusive Avaya Contingent
Liabilities, Avaya shall bear 50% of such Excess Portion and Lucent shall bear
50% of such Excess Portion.

                  (c) In the event that after any payment is made by any party
to the other party in accordance with the allocation set forth in Section
6.3(b), either party or any member of such party's Group receives any Insurance
Proceeds or obtains any other amounts that, in any such case, would reduce the
Value of all amounts paid by such party and the members of its Group in respect
of the applicable Exclusive Contingent Liability or Liabilities, such party will
promptly notify the other party of the receipt of such Insurance Proceeds or
otherwise and will promptly reimburse the other party for the amount of any
payment that such first party would not have


                                      -42-
<PAGE>   48
been entitled to receive if it had received such Insurance Proceeds or obtained
such recovery on or prior to the date it received a payment pursuant to this
Section. Each such repayment will be accompanied by interest accruing from the
date of receipt of the original payment pursuant to this Section to the date of
such repayment at a rate equal to the Prime Rate plus 2% per annum.

                  (d) Each party agrees to use its reasonable best efforts to
advise the other party if it becomes aware of one or more Exclusive Contingent
Liabilities or Related Exclusive Contingent Liabilities that may result in a
Value of $50 million or more; provided, however, that no failure to give any
such notice shall relieve the other party of any obligation pursuant to this
Agreement. In the event of any such notice, or if the other party otherwise
determines that any such risk may exist, the other party will be entitled at its
own expense to monitor any such Action. In any such event, the parties will
enter into a mutually acceptable joint defense agreement so as to maintain to
the extent reasonably practicable the attorney-client privilege, attorney work
product and other judicially recognized protections and privileges with respect
thereto.

                  (e) It shall not be a defense to any obligation by any party
to pay any amount in respect of any Excess Portion that such party was not
consulted in the defense thereof, that such party's views or opinions as to the
conduct of such defense were not accepted or adopted, that such party does not
approve of the quality or manner of the defense thereof or that such Excess
Portion was incurred by reason of a settlement rather than by a judgment or
other determination of liability (even if, subject to Section 5 .5(g), such
settlement was effected without the consent or over the objection of such
party).

         6.4.     Shared Contingent Liabilities

                  (a) As set forth in Section 5.5(c) and subject to Section
5.5(g), Lucent shall assume the defense of, and may seek to settle or
compromise, any Third Party Claim that is a Shared Contingent Liability, and the
costs and expenses thereof shall be included in the calculation of the amount of
the applicable Shared Contingent Liability in determining the reimbursement
obligations of the other parties with respect thereto pursuant to this Section
6.4.

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

         6.5.     Payments

                  (a) Any amount owed in respect of any Shared Contingent
Liabilities (including reimbursement for the cost or expense of defense of (i)
any Third Party Claim that is a Shared Contingent Liability, (ii) any Excess
Portion of any Exclusive Contingent Liabilities or of any


                                      -43-
<PAGE>   49
Related Exclusive Contingent Liabilities or (iii) any Shared Contingent Gains
pursuant to this Article VI shall be remitted promptly after the party entitled
to such amount provides an invoice (including reasonable supporting information
with respect thereto) to the party owing such amount.

                  (b) In the case of any Shared Contingent Liability, Lucent
shall be entitled to reimbursement from Avaya in advance of a final
determination of any Action for amounts paid in respect of costs and expenses
related thereto, from time to time as such costs and expenses are paid. In the
case of any Shared Contingent Gain, Lucent shall be entitled to retain from the
amount of the Shared Contingent Gain otherwise payable to Avaya, Avaya's Shared
Percentage of the costs and expenses paid or incurred by or on behalf of any
member of the Lucent Group in connection with such Shared Contingent Gain.

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

         6.6. Procedures to Determine Status of Contingent Liability or
Contingent Gain

                  (a) With respect to the Actions set forth on Schedule 6.6, and
with respect to any other matters not set forth on Schedules 6.1(f), 6.1(g) or
6.1(k) (regardless of whether such matters are currently pending but not set
forth on such Schedules or are asserted or filed hereafter), Lucent and Avaya
will form the Contingent Claim Committee for the purpose of resolving whether:

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

                           (ii) any Contingent Gain is a Shared Contingent Gain,
an Exclusive Lucent Contingent Gain or an Exclusive Avaya Contingent Gain;

                           (iii) any Liability is a Contingent Liability;

                           (iv) any Contingent Liability is a Shared Contingent
Liability, an Exclusive Lucent Contingent Liability or an Exclusive Avaya
Contingent Liability; or

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

                  (b) Any of the parties may refer any potential Contingent
Gains or Contingent Liabilities to the Contingent Claim Committee for resolution
as described in Section 6.6(a) and if the Contingent Claim Committee reaches a
determination (which shall be made within 30 days of such referral), then that
determination shall be binding on all of the parties and their respective
successors and assigns. In the event that the Contingent Claim Committee cannot
reach a determination as to the nature or status of any such Contingent
Liabilities or Contingent Gains within 30 days after such referral, then the
issue will be submitted to the respective General


                                      -44-
<PAGE>   50
Counsel of Lucent and Avaya for determination. If the General Counsel cannot
reach a determination, then the procedures set forth in Article IX of this
Agreement shall govern.

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

         6.7.     Certain Case Allocation Matters

                  The parties agree that if any Action not set forth on Schedule
6.1(f), 6.1(g) or 6.1(k) involves separate and distinct claims that, if not
joined in a single Action, would constitute separate Exclusive Contingent
Liabilities of two or more parties, they will use their reasonable best efforts
to segregate such separate and distinct claims so that the Liabilities
associated with each such claim (including all costs and expenses) shall be
treated as Exclusive Contingent Liabilities of the appropriate party and so that
each party shall have the rights and obligations with respect to each such claim
(including pursuant to Article V hereof) as would have been applicable had such
claims been commenced as separate Actions. Notwithstanding the foregoing
provisions, this Section 6.7 shall not apply to any separate and distinct claim
that is de minimis or frivolous in nature.

         6.8.     Termination of Certain Article VI Provisions

                  The provisions set forth in this Article VI related to sharing
of Contingent Gains, Contingent Liabilities and the Excess Portion of any
Exclusive Liability shall terminate on the third anniversary of the Distribution
Date except for (i) any claim or action pending or asserted by either party on
or prior to such termination, or (ii) any claim or action related to any matter
that has a statute of limitations that extends beyond such termination date. Any
claim or action referred to in (i) and (ii) above shall survive until the later
of the final determination applicable to any such claim or action or for the
applicable statute of limitations covering such claim or action.


                                   ARTICLE VII
                  INTERIM OPERATIONS AND CERTAIN OTHER MATTERS

         7.1.     Insurance Matters

                  (a) Lucent and Avaya agree to cooperate in good faith to
provide for an orderly transition of insurance coverage for the treatment of any
Insurance Policies that will remain in effect following the Distribution Date on
a mutually agreeable basis. In no event shall Lucent, any other member of the
Lucent Group or any Lucent Indemnitee have liability or obligation whatsoever to
any member of the Avaya Group in the event that any Insurance Policy or other


                                      -45-
<PAGE>   51
contract or policy of insurance shall be terminated or otherwise cease to be in
effect for any reason, shall be unavailable or inadequate to cover any Liability
of any member of the Avaya Group for any reason whatsoever or shall not be
renewed or extended beyond the current expiration date.

                  (b) (i) Except as otherwise provided in any Ancillary
Agreement, the parties intend by this Agreement that Avaya and each other member
of the Avaya Group be successors-in-interest to all rights that any member of
the Avaya Group may have as of the Distribution Date as a subsidiary, affiliate,
division or department of Lucent prior to the Distribution Date under any policy
of insurance issued to Lucent by any insurance carrier or under any agreements
related to such policies executed and delivered prior to the Distribution Date,
including any rights such member of the Avaya Group may have, as an insured or
additional named insured, subsidiary, affiliate, division or department, to
avail itself of any such policy of insurance or any such agreements related to
such policies as in effect prior to the Distribution Date. At the request of
Avaya, Lucent shall take all reasonable steps, including the execution and
delivery of any instruments, to effect the foregoing; provided, however that
Lucent shall not be required to pay any amounts, waive any rights or incur any
Liabilities in connection therewith.

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

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

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

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

         7.2.     Operating Financial Liabilities

                  (a) As between Lucent and Avaya, Avaya hereby irrevocably
assumes and agrees to pay, perform, satisfy and discharge all liabilities,
obligations, contingencies and other Liabilities under, or otherwise relating
to, arising out of or resulting from, all Avaya OFL's. For purposes of this
Agreement, the term "Avaya OFL" means the OFL's listed or described on Schedule
7.2(a) and any other OFL's that are primarily related to, arise out of or result
from any Avaya Asset, Avaya Liability (including any Avaya Contract) or Avaya
Business or that were otherwise entered into in connection with the conduct of
the Avaya Business. The parties hereto acknowledge that there may be OFL's that
are Avaya OFL's that are not set forth or described on such Schedule 7.2(a)
because such OFL's were inadvertently excluded from such Schedule. As a result,
the parties agree to cooperate in good faith to supplement Schedule 7.2(a) as
any additional Avaya OFL's are identified. In the event that any OFL is so added
to such Schedule 7.2(a), Lucent will retroactively bill Avaya in accordance with
this Section 7.2 for any amount payable by any member of the Lucent Group on or
after the date hereof, and Lucent will retroactively credit Avaya in accordance
with this Section 7.2 for any amount paid to any member of the Lucent Group on
or after the date hereof, together in each case with interest thereon from the
date of payment by or to any such member of the Lucent Group, as the case may
be, to the date of settlement of such bill or credit, at the Lucent CP Rate that
would have been applicable if such Avaya OFL had originally been included on
Schedule 7.2(a), subject to increase pursuant to Section 7.2(c)(ii).

                  (b) (i) Lucent may, from time to time, set forth on Schedule
7.2(a) whether any Avaya OFL's are to be paid, performed, satisfied and
discharged directly by Avaya. Lucent may at any time or from time to time on at
least 30 days' written notice to Avaya, modify such Schedule 7.2(a) to change
whether any Avaya OFL shall thereafter be paid, performed, satisfied and
discharged directly by Avaya or by Lucent. Lucent shall, in the absence of any
default by Avaya under this Section 7.2, pay, or cause to be paid, all other
Avaya OFL's, and Avaya agrees to reimburse Lucent for such payments in
accordance with the terms of this Section 7.2. If Avaya is in default of any of
its obligations under this Section 7.2, Lucent shall no longer be required to
pay, or cause to be paid, any Avaya OFL's and Avaya shall be required directly
to pay, perform, satisfy and discharge such Avaya OFL's.

                           (ii) In the event that payments are made by a third
party under any Avaya OFL, if Avaya is not in default of any of its obligations
under this Section 7.2, (A) if any such payment is made to any member of the
Avaya Group, such member of the Avaya Group will be entitled to retain any such
payments received by it, and (B) if any such payment is made to any member of
the Lucent Group, such member of the Lucent Group shall, at Lucent's election,
either remit any such amounts it receives to Avaya or net such amounts against
payments Lucent is then required to make under any other Avaya OFL or against
payments then owed (whether or not then due) to Lucent by Avaya hereunder.

                           (iii) In the event that payments are made by a third
party under any Avaya OFL, if Avaya is in default of any of its obligations
under this Section 7.2, (A) if any such payment is made to any member of the
Avaya Group, Avaya shall promptly remit any such


                                      -47-
<PAGE>   53
payments to Lucent, and (B) if any such payment is made to any member of the
Lucent Group, Lucent shall be entitled (but not required, to apply any such
payments to satisfy, any such breach by Avaya, either, at Lucent's option) by
netting amounts then owed (whether or not then due) to Lucent by Avaya hereunder
or by paying over such monies in order to satisfy any obligation in respect of
any Avaya OFL.

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

                  (c) (i) Lucent shall issue a statement to Avaya for the
payments due from or payable to Avaya pursuant to this Section 7.2 in respect of
any month by the tenth business day of the following month. Each such statement
shall set forth the Lucent CP Rate for the immediately preceding month. Interest
will accrue and be payable by Avaya on all amounts due pursuant to this section
7.2 in respect of Avaya OFL's at the Lucent CP Rate in effect for the month
immediately preceding the month in which the statement is issued from the date
of payment of any such amount by any member of the Lucent Group under any Avaya
OFL to the date of payment therefor to Lucent by Avaya. In the event payments
are due by Lucent to Avaya under this Section 7.2, Lucent will pay interest at
the Lucent CP Rate in effect for the month immediately preceding the month in
which the statement is issued from the date of receipt by Lucent under an Avaya
OFL to the date of payment by Lucent. All payments under this Section 7.2 shall
be in same day funds.

                      (ii) Avaya agrees to pay Lucent any amounts due (including
in respect of interest) within 10 days of receipt of each statement. Lucent will
remit to Avaya any payments (including in respect of interest) received by any
member of the Lucent Group under any Avaya OFL (to the extent not netted in
accordance with Section 7.2(b)) within 10 days of the date of statement. Any
amounts not paid when due shall bear interest at the Prime Pate plus 2% per
annum in lieu of the Lucent CP Rate.

                  (d) (i) Avaya may prepay (or effect the early termination) of
any Avaya OFL's provided that no additional Liability is thereby created for any
member of the Lucent Group other than any Liabilities that are fully discharged
and satisfied by Avaya simultaneously with such prepayment or early termination.

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

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


                                      -48-
<PAGE>   54
                           (iv) In the event that Avaya makes any payment in
respect of an Avaya OFL, Avaya will be subrogated to all rights of Lucent or any
member of the Lucent Group with respect to such Avaya OFL, including with
respect to collateral, to the extent of such payment.

         7.3.     Certain Business Matters

                  Subject to Section 2.15, no member of any Group shall have any
duty to refrain from (i) engaging in the same or similar activities or lines of
business as any member of any other Group, (ii) doing business with any
potential or actual supplier or customer of any member of any other Group, or
(iii) engaging in, or refraining from, any other activities whatsoever relating
to any of the potential or actual suppliers or customers of any member of any
other Group.

         7.4.     Late Payments

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


                                  ARTICLE VIII
                    EXCHANGE OF INFORMATION; CONFIDENTIALITY

         8.1.     Agreement for Exchange of Information; Archives

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

                  (b) After the Distribution Date, Avaya shall have access
during regular business hours (as in effect from time to time) to the documents
and objects of historic significance that relate to the Avaya Business that are
located in archives retained or maintained by Lucent.


                                      -49-
<PAGE>   55
Avaya may obtain copies (but not originals) of documents for bona fide business
purposes and may obtain objects for exhibition purposes for commercially
reasonable periods of time if required for bona fide business purposes, provided
that Avaya shall cause any such objects to be returned promptly in the same
condition in which they were delivered to Avaya and Avaya shall comply with any
rules, procedures or other requirements, and shall be subject to any
restrictions (including prohibitions on removal of specified objects), that are
then applicable to Lucent. Avaya shall pay the applicable fee or rate per hour
for archives research services (subject to increase from time to time to reflect
rates then in effect for Lucent generally). Nothing herein shall be deemed to
restrict the access of any member of the Lucent Group to any such documents or
objects or to impose any liability on any member of the Lucent Group if any such
documents or objects are not maintained or preserved by Lucent.

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

         8.2.     Ownership of Information

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

         8.3.     Compensation for Providing Information

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

         8.4.     Record Retention

                  To facilitate the possible exchange of Information pursuant to
this Article VIII and other provisions of this Agreement after the Distribution
Date, the parties agree to use their reasonable best efforts to retain all
Information in their respective possession or control on the Distribution Date
in accordance with the policies of Lucent as in effect on the Distribution Date
or such other policies as may be reasonably adopted by the applicable party
after the Distribution Date. No party will destroy, or permit any of its
Subsidiaries to destroy, any Information which the other party may have the
right to obtain pursuant to this Agreement prior to the third anniversary of the
date hereof without first using its reasonable best efforts to notify the other

party of the proposed destruction and giving the other party the opportunity to
take possession of such information prior to such destruction; provided,
however, that in the case of any Information relating to Taxes, employee
benefits or to Environmental Liabilities, such period shall be extended to the
expiration of the applicable statute of limitations (giving effect to any
extensions thereof) ; provided further, however, that in the event that any such
Information is also subject to a retention requirement contained in any
Ancillary Agreement that is longer than the requirement contained in this
Section 8.4, then the requirement in such agreement shall supersede this Section
8.4.

         8.5.     Limitations of Liability

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

         8.6.     Other Agreements Providing for Exchange of Information

                  The rights and obligations granted under this Article VIII are
subject to any specific limitations, qualifications or additional provisions on

Ancillary Agreement.

         8.7.     Production of Witnesses; Records; Cooperation

                  (a) After the Distribution Date, except in the case of an
adversarial Action by one party against another party, each party hereto shall
use its reasonable best efforts to make available to each other party, upon
written request, the former, current and future directors, officers, employees,
other personnel and agents of the members of its respective Group as witnesses
and any books, records or other documents within its control or which it
otherwise has the ability to make available, to the extent that any such person
(giving consideration to business demands of such directors, officers,
employees, other personnel and agents) or books, records or other documents may
reasonably be required in connection with any Action in which the requesting
party may from time to time be involved, regardless of whether such Action is a
matter with respect to which indemnification may be sought hereunder. The
requesting party shall bear all costs and expenses in connection therewith.

                  (b) If an Indemnifying Party or Lucent chooses to defend or to
seek to compromise or settle any Third Party Claim, or if any party chooses to
prosecute or otherwise evaluate or to pursue any Contingent Gain, the other
parties shall make available to such Indemnifying Party, Lucent or such other
party, as the case may be, upon written request, the former, current and future
directors, officers, employees, other personnel and agents of the members of its
respective Group as witnesses and any books, records or other documents within
its control or which it otherwise has the ability to make available, to the
extent that any such person (giving consideration to business demands of such
directors, officers, employees, other


                                      -51-
<PAGE>   57
personnel and agents) or books, records or other documents may reasonably be
required in connection with such defense, settlement or compromise, or such
prosecution, evaluation or pursuit, as the case may be, and shall otherwise
cooperate in such defense, settlement or compromise, or such prosecution,
evaluation or pursuit, as the case may be.

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

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

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

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

         8.8.     Confidentiality

                  (a) Subject to Section 8.9, each of Lucent and Avaya, on
behalf of itself and each member of its respective Group, agrees to hold, and to
cause its respective directors, officers, employees, agents, accountants,
counsel and other advisors and representatives to hold, in strict confidence,
with at least the same degree of care that applies to Lucent's confidential and
proprietary information pursuant to policies in effect as of the Distribution
Date, all Information concerning each such other Group that is either in its
possession (including Information in its possession prior to any of the date
hereof or the Distribution Date) or furnished by any such other Group or its
respective directors, officers, employees, agents, accountants, counsel and
other advisors and representatives at any time pursuant to this Agreement, any
Ancillary Agreement or otherwise, and shall not use any such Information other
than for such purposes as shall be expressly permitted hereunder or thereunder,
except, in each case, to the extent that such Information has been (i) in the
public domain through no fault of such party or any member of such Group or any
of their respective directors, officers, employees, agents, accountants, counsel
and other advisors and representatives, (ii) later lawfully acquired from other
sources by such party (or any member of such party's Group) which sources are
not themselves bound by a confidentiality obligation), or (iii) independently
generated without reference to any proprietary or confidential Information of
the other party.


                                      -52-
<PAGE>   58
                  (b) Each party agrees not to release or disclose, or permit to
be released or disclosed, any such Information to any other Person, except its
directors, officers, employees, agents, accountants, counsel and other advisors
and representatives who need to know such Information (who shall be advised of
their obligations hereunder with respect to such Information), except in
compliance with Section 8.9. Without limiting the foregoing, when any
Information is no longer needed for the purposes contemplated by this Agreement
or any Ancillary Agreement, each party will promptly after request of the other
party either return to the other party all Information in a tangible form
(including all copies thereof and all notes, extracts or summaries based
thereon) or certify to the other party that it has destroyed such Information
(and such copies thereof and such notes, extracts or summaries based thereon).

         8.9.     Protective Arrangements

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


                                   ARTICLE IX
                               DISPUTE RESOLUTION

         9.1.     Disputes

                  Except as otherwise specifically provided in any Ancillary
Agreement, the procedures for discussion, negotiation and mediation set forth in
this Article IX shall apply to all disputes, controversies or claims (whether
arising in contract, tort or otherwise) that may arise out of or relate to, or
arise under or in connection with this Agreement or any Ancillary Agreement, or
the transactions contemplated hereby or thereby (including all actions taken in
furtherance of the transactions contemplated hereby or thereby on or prior to
the date hereof), or the commercial or economic relationship of the parties
relating hereto or thereto, between or among any member of the Lucent Group and
the Avaya Group.

         9.2.     Escalation; Mediation

                  (a) It is the intent of the parties to use their respective
reasonable best efforts to resolve expeditiously any dispute, controversy or
claim between or among them with respect to the matters covered hereby that may
arise from time to time on a mutually acceptable negotiated basis. In
furtherance of the foregoing, any party involved in a dispute, controversy or
claim may


                                      -53-
<PAGE>   59
deliver a notice (an "Escalation Notice") demanding an in person meeting
involving representatives of the parties at a senior level of management of the
parties (or if the parties agree, of the appropriate strategic business unit or
division within such entity). A copy of any such Escalation Notice shall be
given to the General Counsel, or like officer or official, of each party
involved in the dispute, controversy or claim (which copy shall state that it is
an Escalation Notice pursuant to this Agreement). Any agenda, location or
procedures for such discussions or negotiations between the parties may be
established by the parties from time to time; provided, however, that the
parties shall use their reasonable best efforts to meet within 30 days of the
Escalation Notice.

                  (b) If the parties are not able to resolve the dispute,
controversy or claim through the escalation process referred to above, then the
matter shall be referred to mediation. The parties shall retain a mediator to
aid the parties in their discussions and negotiations by informally providing
advice to the parties. Any opinion expressed by the mediator shall be strictly
advisory and shall not be binding on the parties, nor shall any opinion
expressed by the mediator be admissible in any other proceeding. The mediator
may be chosen from a list of mediators previously selected by the parties or by
other agreement of the parties. Costs of the mediation shall be borne equally by
the parties involved in the matter, except that each party shall be responsible
for its own expenses. Mediation shall be a prerequisite to the commencement of
any action by either party.

         9.3.     Court Actions

                  (a) In the event that any party, after complying with the
provisions set forth in Section 9.2 above, desires to commence an Action, such
party may submit the dispute, controversy or claim (or such series of related
disputes, controversies or claims) to any court of competent jurisdiction.

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


                                    ARTICLE X
                   FURTHER ASSURANCES AND ADDITIONAL COVENANTS

         10.1.    Further Assurances

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


                                      -54-
<PAGE>   60
                  (b) Without limiting the foregoing, prior to, on and after the
Distribution Date, each party hereto shall cooperate with the other party, and
without any further consideration, but at the expense of the requesting party,
to execute and deliver, or use its reasonable best efforts to cause to be
executed and delivered, all instruments, including instruments of conveyance,
assignment and transfer, and to make all filings with, and to obtain all
consents, approvals or authorizations of, any Governmental Authority or any
other Person under any permit, license, agreement, indenture or other instrument
(including any Consents or Governmental Approvals), and to take all such other
actions as such party may reasonably be requested to take by any other party
hereto from time to time, consistent with the terms of this Agreement and the
Ancillary Agreements, in order to effectuate the provisions and purposes of this
Agreement and the Ancillary Agreements and the transfers of the Avaya Assets and
the assignment and assumption of the Avaya Liabilities and the other
transactions contemplated hereby and thereby. Without limiting the foregoing,
each party will, at the reasonable request, cost and expense of any other party,
take such other actions as may be reasonably necessary to vest in such other
party good and marketable title, free and clear of any Security Interest, if and
to the extent it is practicable to do so.

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

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

                  (e) Lucent and Avaya, and each of the members of their
respective Groups, waive (and agree not to assert against any of the others) any
claim or demand that any of them may have against any of the others for any
Liabilities or other claims relating to or arising out of: (i) the failure of
Avaya or any member of the Avaya Group, on the one hand, or of Lucent or any
member of the Lucent Group, on the other hand, to provide any notification or
disclosure required under any state Environmental Law in connection with the
Contribution or the other transactions contemplated by this Agreement, including
the transfer by any member of any Group to any member of any other Group of
ownership or operational control of any Assets not previously owned or operated
by such transferee; or (ii) any inadequate, incorrect or incomplete notification
or disclosure under any such state Environmental Law by the applicable
transferor. To the extent any Liability to any Governmental Authority or any
third Person arises out of any action or inaction described in clause (i) or
(ii) above, the transferee of the applicable Asset hereby assumes and agrees to
pay any such Liability.

                  (f) Prior to the Distribution Date, if one or more of the
parties identifies any commercial or other service that is needed to assure a
smooth and orderly transition of the businesses in connection with the
consummation of the transactions contemplated hereby, and that is not otherwise
governed by the provisions of this Agreement or any Ancillary Agreement,


                                      -55-
<PAGE>   61
the parties will cooperate in determining whether there is a mutually acceptable
arm's-length basis on which one or more of the other parties will provide such
service.

         10.2.    Qualifications as Tax-Free Distribution

                  After the Distribution Date, neither Lucent nor Avaya shall
take, or permit any member of its respective Group to take, any action which
could reasonably be expected to prevent the Distribution from qualifying as a
tax-free distribution within the meaning of Section 355 of the Code or any other
transaction contemplated by this Agreement or any Ancillary Agreement which is
intended by the parties to be tax-free from failing so to qualify.

         10.3.    Changes in Avaya Stock Ownership Following the Distribution

                  (a) For each proposed Change in Avaya Stock Ownership
occurring during the two-year period following the Distribution after which the
Avaya Cumulative Ownership Change will exceed 25 percent, Avaya agrees that
prior to consummating such Change in Avaya Stock Ownership it will (i) notify
Lucent of such proposed agreement or plan, and (ii) not consummate such
agreement or plan unless (1) Lucent shall have obtained a Supplemental Ruling in
accordance with Section 6.5(e) of the Tax Sharing Agreement that the
consummation of such agreement or plan will not effect the treatment of the
Distribution under Section 355 of the Code; or (2) Avaya shall have obtained an
opinion of Cravath, Swaine & Moore (or other nationally recognized tax counsel
acceptable to Lucent) that the consummation of such agreement or plan will not
effect the treatment of the Distribution under Section 355 of the Code; or (3)
Lucent shall have waived the requirement to obtain such a ruling or opinion, or
(4) Avaya and the other party or parties to the proposed Change in Avaya Stock
Ownership shall have agreed to indemnify Lucent, on an after-tax basis, from and
against any and all tax liabilities that may be imposed on Lucent as a result of
the proposed Change in Avaya Stock Ownership, including, but not limited to, any
tax imposed under Section 355(e) of the Code, which indemnification is
acceptable to Lucent in its sole discretion and is supported with appropriate
credit assurance, such as an escrow or a line of credit. Notwithstanding the
foregoing, if a proposed Change in EN Stock Ownership is a result of
negotiations, discussions or similar transactions that occurred at any time
during the two-year period following the Distribution, then the preceding
sentence shall apply to each such proposed Change in EN Stock Ownership during
the three-year period following the Distribution.

                  (b) If Avaya notifies Lucent of a proposed agreement or plan
under this Section 10.3, Avaya and Lucent shall reasonably cooperate to attempt
to obtain the IRS ruling or opinion of counsel referred to in the preceding
sentence, unless Lucent shall have waived the requirement to obtain such ruling
or opinion.

                  (c) For all Changes in Avaya Stock Ownership occurring during
the two-year period following the Distribution after which the Avaya Cumulative
Ownership Change will not exceed 25 percent, Avaya agrees that within 30 days
after entering into an agreement or adopting a plan to consummate such Change in
Avaya Stock Ownership, it will notify Lucent of such agreement or plan and
provide Lucent with complete details as to how the proposed Change in Avaya
Stock Ownership will impact the Avaya Cumulative Ownership Change.

         10.4.    Compliance with Separation and Distribution Agreement

                  From and after the date hereof, Avaya agrees to comply with
and abide by the provisions of the SDA Agreement applicable to Avaya, including,
without limitation, Section


                                      -56-

                  No party shall be deemed in default of this Agreement or any
Ancillary Agreement to the extent that any delay or failure in the performance
of its obligations under this Agreement or any Ancillary Agreement results from
any cause beyond its reasonable control and without its fault or negligence,
such as acts of God, acts of civil or military authority, embargoes, epidemics,
war, riots, insurrections, fires, explosions, earthquakes, floods, unusually
severe

weather conditions, labor problems or unavailability of parts, or, in the case
of computer systems, any failure in electrical or air conditioning equipment. In
the event of any such excused delay, the time for performance shall be extended
for a period equal to the time lost by reason of the delay.

         12.8.    Publicity

                  Prior to the Distribution, each of Lucent and Avaya shall
consult with each other prior to issuing any press releases or otherwise making
public statements with respect to the Contribution, the Distribution or any of
the other transactions contemplated hereby and prior to making any filings with
any Governmental Authority with respect thereto.

         12.9.    Expenses

                  Except as otherwise provided herein, all third party fees,
costs and expenses paid or incurred in connection with the Distribution will be
paid by Avaya.

         12.10.   Headings

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

         12.11.   Survival of Covenants

                  Except as expressly set forth in any Ancillary Agreement, the
covenants, representations and warranties contained in this Agreement and each
Ancillary Agreement, and liability for the breach of any obligations contained
herein, shall survive the Contribution and the Distribution and shall remain in
full force and effect.

         12.12.   Waivers of Default

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

         12.13.   Specific Performance

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


                                      -60-

is waived. Any requirements for the securing or posting of any bond with such
remedy are waived.

         12.14.   Amendments

                  No provisions of this Agreement or any Ancillary Agreement
shall be deemed waived, amended, supplemented or modified by any party, unless
such waiver, amendment, supplement or modification is in writing and signed by
the authorized representative of the party against whom it is sought to enforce
such waiver, amendment, supplement or modification.


         12.15.   Interpretation

                  Words in the singular shall be held to include the plural and
vice versa and words of one gender shall be held to include the other genders as
the context requires. The terms "hereof," "herein," and "herewith" and words of
similar import shall, unless otherwise stated, be construed to refer to this

particular provision of this Agreement (or such Ancillary Agreement). Article,
Section, Exhibit, Schedule and Appendix references are to the Articles,
Sections, Exhibits, Schedules and Appendices to this Agreement (or the
