addition to assuming the Assumed Liabilities, Buyer shall pay to Seller at the
Closing, $310,400,000 (as may be adjusted in accordance with this Section 2.3)
(the "PURCHASE PRICE"). The payment to be made by Buyer to Seller in respect of
the Purchase Price on the Closing Date shall be made in cash by wire transfer of
immediately available funds to an account designated by Seller's written
instructions to Buyer at least two (2) Business Days prior to Closing, prior to
the Closing Date. In addition to the foregoing, the Buyer shall pay to the

         (b) On the date which is five (5) Business Days prior to the Closing
Date (the "Cut-Off Date"), Seller shall prepare and deliver to Buyer an
unaudited balance sheet of the Business as of the Cut-Off Date substantially in
the form of the Initial Balance Sheet (the "CUT-OFF BALANCE SHEET"). Seller
agrees to deliver to Buyer all drafts of the Cut-Off Balance Sheet prepared by
Seller from and after the date hereof and prior to and in connection with the
preparation of the final Cut-Off Balance Sheet. Buyer shall be given full access
to the relevant records and working papers used by Seller to prepare the Cut-Off

conduct of the physical inventory of the Principal Equipment and the Purchased
Inventory, Buyer shall advise Seller whether it believes that the Cut-Off
Balance Sheet materially reflects the balance sheet of the Business as of the
Cut-Off Date. In the event Buyer agrees with the Cut-Off Balance Sheet, the
Purchase Price shall be adjusted to reflect the Net Asset Value as reflected on
the Cut-Off Balance Sheet (the "CUT-OFF NET ASSET VALUE"). In the event Buyer
disagrees with the Cut-Off Balance Sheet, the parties shall use their respective
best good faith efforts to resolve such disagreement within five (5) days of
receipt by Buyer of the Cut-Off Balance Sheet; PROVIDED, HOWEVER, that if the
parties cannot come to an agreement within such five (5) day period, then on the
Closing Date the Purchase Price shall be adjusted to reflect the Cut-Off Net
Asset Value.

<PAGE>


         (c) In the event that the parties cannot agree on the Cut-Off Net Asset
Value by the Closing Date, Buyer shall, within forty-five (45) days following
the Closing Date, give written notice to Seller of any proposed changes to be
made to the Cut-Off Balance Sheet or of its inability to confirm whether such
balance sheet has been prepared in a manner consistent with the preparation of
the Initial Balance Sheet (a "MATERIAL UNCERTAINTY"), describing the change or
Material Uncertainty and the basis for the change or Material Uncertainty in
reasonable detail. Failure to so notify Seller shall constitute acceptance and
approval of the Cut-Off Balance Sheet. If Seller agrees that a proposed change
is appropriate, the change shall be made to the Cut-Off Balance Sheet. If Seller
does not agree that any proposed change is appropriate, and Buyer and Seller
cannot agree on the treatment of the proposed change, the Seller and Buyer shall
select an auditor from a national certified public accounting firm, other than
the Seller's or the Buyer's external auditors, who shall decide if the change is
appropriate, and the Cut-Off Balance Sheet will be adjusted in accordance with
such auditor's decision. The balance sheet so adjusted shall be referred to as
the "CLOSING BALANCE SHEET." Buyer and Seller shall each pay one-half of the
reasonable fee charged by such auditor.

         (d) The Closing Balance Sheet shall include a calculation of the Net
Asset Value of the Business as of the Closing Date (such amount as set forth in
the Closing Balance Sheet, the "FINAL NET ASSET VALUE"). If the Cut-Off Net
Asset Value is less than the Final Net Asset Value by an amount in excess of $1
million, Buyer shall pay the amount by which the Final Net Asset Value exceeds
the Cut-Off Net Asset Value to Seller, and if the Cut-Off Net Asset Value is
greater than the Final Net Asset Value by an amount in excess of $1 million,
Seller shall pay the amount by which the Cut-Off Net Asset Value exceeds the
Final Net Asset Value to Buyer. Any such payment shall be made on or before
fifty (50) calendar days after the Closing Date, and any such payment shall be
considered an addition or reduction, as applicable, to the Purchase Price.

2.4      ASSUMED LIABILITIES

         On the Closing Date, Buyer shall execute and deliver to Seller the one
or more Assumption Agreements pursuant to which Buyer shall accept, assume and

                  of the accrued but unused vacation of such Initially

                  or the Purchased Assets, known or unknown, absolute or
                  contingent, arising on or after the Closing Date, and the
                  obligations and liabilities with respect to the Transferred
                  Employees arising on or after their Transfer Date, in each
                  case known or unknown, absolute or contingent.

2.5      EXCLUDED LIABILITIES

obligations not so assumed being referred to herein as the "EXCLUDED
LIABILITIES").

their successors and assigns, the assumption of the liabilities and obligations
intended to be assumed by Buyer under this Agreement and the Collateral
Agreements, and to otherwise make effective the transactions contemplated hereby
and thereby.

         (c) Nothing in this Agreement nor the consummation of the transactions
contemplated hereby shall be construed as an attempt or agreement to assign any
Purchased Asset, including any Contract, License, Governmental Permit,
certificate, approval, authorization or other right, which by its terms or by
Law is nonassignable without the consent of a Third Party or a Governmental Body
or is cancellable by a Third Party in the event of an assignment ("NONASSIGNABLE
ASSETS") unless and until such consents shall be given. Seller agrees, and
agrees to cause its Affiliates, to cooperate with Buyer at its request to use
reasonable commercial efforts to obtain such consents promptly; PROVIDED,

obligations or liabilities that constitute Assumed Liabilities or to obtain in
writing the unconditional release of Seller and its Affiliates so that, in any
such case, Buyer and its Affiliates shall be solely responsible for such

otherwise as Buyer may reasonably request so as to provide Buyer with the
benefits of the Nonassignable Assets and to effect collection of money or other
consideration to become due and payable under the Nonassignable Assets, and
Seller or its Affiliates shall promptly pay over to Buyer all money or other
consideration received by it in respect to all Nonassignable Assets.

         (e) As of and from the Closing Date, Seller on behalf of itself and its
Affiliates authorizes Buyer, to the extent permitted by applicable Law and the
terms of the Nonassignable Assets, at Buyer's expense, to perform all the
obligations and receive all the benefits of Seller or its Affiliates under the

Affiliate's behalf with respect thereto.

the Supply Agreement, no title, right or license of any kind is granted to Buyer
pursuant to this Agreement with respect to Seller's or any of its Affiliate's
Proprietary Information, either directly or indirectly, by implication, by
estoppel or otherwise.

and ending on the first anniversary of the Closing Date to fulfill its
obligations to Seller under the Supply Agreement (other than Purchased Inventory
which has been or is required to be returned to or purchased by Seller pursuant
to the Supply Agreement) ("REMAINING PURCHASED INVENTORY"), Buyer shall have the
right to cause Seller to purchase up to ninety million dollars (US$90,000,000)
of the Remaining Purchased Inventory as specified below, upon providing Seller
with a notice setting forth the amount of such Remaining Purchased Inventory and
applicable purchase price. The purchase price of the Remaining Purchased
Inventory shall be equal to the purchase price paid by Buyer to Seller for the
Remaining Purchased Inventory hereunder, provided that the aggregate amount of
the purchase price payable by Seller to Buyer for the Remaining Purchased
Inventory under this Section 2.10 and Section 2.10 of the Columbus APA shall not

to be acquired under this Agreement and the Collateral Agreements (including the
services to be provided pursuant to the Transition Services Agreement)

license any assets, properties or Proprietary Information or provide any
services used in the Business, such breach shall be deemed cured if Seller
promptly transfers such properties or assets, licenses such Proprietary
Information or provides such services to Buyer, and Buyer shall have no further

knowledge, no proceeding is pending or threatened to revoke or limit any such
Governmental Permit. Seller has provided to Buyer a true and complete copy of

Licenses which would require over the full term thereof payments by or to Seller

                            conduct of the Business and are not generally
                            observed by the public or are intended for use as

                            MARKED ASSETS"). For the purposes of this Section
                            5.9, "REASONABLE EFFORTS" means Buyer shall remove
                            Seller Name from such Other Marked Assets but only

                            otherwise is taken out of service in the normal
                            course of business due to regular maintenance or
                            repair (but only for such repairs or maintenance
                            where such removal could normally be undertaken, for
                            example, repair or maintenance of a mold cavity)
                            whichever occurs first; PROVIDED that, in no event
                            shall Buyer use Seller Name after the date which is
                            six (6) months from the Closing Date. Buyer shall
                            not be required to perform such removal on such
                            Other Marked Assets that are not or no longer used
                            to manufacture the products of the Business or other
                            parts, or if discontinuance of use of such Other
                            Marked Assets is reasonably anticipated during such
                            time period; provided, such Other Marked Assets are
                            not sold or otherwise transferred to a Third Party
                            absent Lucent's prior written approval.

                  (v)      Seller hereby grants to Buyer a limited right to use
                           Seller Marks with regard to the Marked Assets,

                           owner of Seller Marks and all goodwill attached
                           thereto. This Agreement does not give Buyer any
                           interest in Seller Marks except the right to use
                           Seller

                            relevant Laws and requirements of Governmental

                                 (III)    potential Hazardous Substances in and
                                          from the transformer at the nitrogen

             (v)            The Investigation will continue following the date
                            hereof with the intent of completing the
                            Investigation within three months from the date
                            hereof. Seller and Buyer acknowledge that the
                            completion of the Investigation shall most likely
                            occur following the Closing Date and that the
                            completion of the Investigation shall not be a
                            condition to the Closing.

             (vi)           The reports to be produced  recording matters
                            relevant to the Investigation, including the Phase I
                            and Phase II Environmental Site Assessments, (the
                            "Reports") shall, among other things, set out the
                            location, likely extent and concentration of each
                            Hazardous Substance discovered in, on, under, about
                            or from the Oklahoma Premises. The parties will have
                            an opportunity to review and comment on the draft
                            Reports upon their becoming available and before
                            being prepared by the Consultant in final form and
                            Consultant shall by instructed to consider and
                            incorporate on a reasonable basis all reasonable
                            comments of the parties. Seller shall keep the
                            Reports confidential except that Seller shall be
                            entitled to provide copies of the Reports on a
                            confidential basis to such Persons reasonably
                            determined by Seller to require such information to
                            effectuate the provisions of this Section 5.10 as is
                            required by applicable Law, by securities regulatory
                            authorities and stock exchanges or in connection
                            with any dispute relating hereto. Seller and Buyer
                            agree that the Reports shall constitute
                            non-exclusive evidence of the environmental and

                            Described EH&S Conditions".

             (vii)          Buyer shall pay all fees of the Consultant in
                            connection with the Investigation, including the
                            preparation of and finalization of the Reports, and
                            Seller and Buyer shall each otherwise be responsible
                            for any costs such party incurs in connection
                            therewith.

             (viii)         Seller,  at its sole  cost,  shall  promptly  take
                            all action required by Environmental Law to
                            investigate, remediate or otherwise resolve the
                            issues related to the Golder Described EH&S
                            Conditions (including, without limitation, the
                            presence or release of Hazardous Substances) and
                            will retain all liability for and the responsibility
                            to address the Golder Described EHS Conditions to
                            the extent that the Golder Described EHS Conditions
                            are not so investigated, remediated or resolved with
                            from time to time. The parties acknowledge that the
                            fact that the Consultant describes a matter as an
                            environmental or health and safety condition does
                            not determine whether or not such matter requires
                            investigation, remediation or other resolution under
                            Environmental Law. All action of Seller shall be
                            conducted in a manner complying with Environmental
                            Law and other relevant Laws and requirements of
                            Governmental Bodies, which shall include without
                            limitation minimizing interference (to the extent
                            practicable) with activities of Buyer and others on
                            the Oklahoma Premises, using reasonably competent
                            personnel as selected by Seller to accomplish such
                            objectives and restoring the Oklahoma Premises to a
                            condition after such action consistent with the use
                            of such Premises for activity of the type (i.e.
                            industrial) presently conducted by Seller.

             (ix)           To the extent that remediation involves the use of
                            engineering and/or institutional controls acceptable
                            to Buyer and Hazardous Substances are permitted to
                            remain on the Oklahoma Premises, Seller shall remain
                            liable for and shall be responsible for all future
                            costs associated with maintaining the engineering
                            and institutional controls.

             (x)            Buyer shall cooperate with Seller as necessary to
                            effectuate the provisions of this Section 5.10
                            (including without limitation furtherance of the
                            investigatory and remedial actions set forth above)
                            in accordance with the provisions of this Agreement
                            provided that all reasonable costs thereof shall be

(with the understanding that each party shall include in its initial application
the preferred redactions being sought by the other party). Each party agrees

the Business Day prior to the Closing Date, the parties may modify Schedule 5.4
to reflect the Initially Transferred Employees, if any, to whom Buyer will offer
employment on the Closing Date based solely on Buyer's assessment of its
business needs. Seller and Buyer shall work together, acting reasonably and in
good faith, to agree on any changes to Schedules effected pursuant to (ii)
above, and to use their reasonable efforts to ensure that Closing is not delayed
as a result of changes to Schedules pursuant to (ii) above.

5.13     SURPLUS ASSETS

         For a period of six (6) months following the Closing Date, Buyer shall
have an option to purchase from Seller certain Excluded Assets, which shall be
identified on Schedule 2.2(i) as being subject to this Section 5.13, upon
providing Seller with a notice identifying such Excluded Assets and the

Excluded Assets, Seller shall notify Buyer and Buyer shall have five (5)

destroyed. The purchase price of such Excluded Assets shall be equal to the
lesser of the net book value of such Excluded Assets at the Closing Date and the

the purchase price applicable to such Excluded Assets no later than ten (10)
Business Days following the receipt by Seller of the relevant notice provided by
Buyer and upon delivery by Seller to Buyer of such Excluded Assets.

5.14     BUSINESS SERVICES AGREEMENT

         Prior to the Closing Date, Buyer and Seller shall use all reasonable

         Buyer agrees that the Confidentiality Agreement shall apply to (a) all

therewith and the preparation of this Agreement and related documents and (b)
all analyses, reports, compilations, evaluations and other materials prepared by
Buyer or its counsel, accountants or financial advisors that contain or
otherwise reflect or are based upon, in whole or in part, any of the provided
information; PROVIDED, HOWEVER, that subject to Section 6.2(a), the
Confidentiality Agreement shall terminate as of the Closing and shall be of no
further force and effect thereafter with respect to information of Seller the
ownership of which is transferred to Buyer.

6.2      SELLER'S PROPRIETARY INFORMATION

         (a) Except as provided in Section 6.2(b) and 6.2(d), and except as
otherwise provided in the Intellectual Property Agreement or the Supply

market testing information, development plans, specifications, customer

         (b) Notwithstanding the foregoing, such Proprietary Information shall
not be deemed confidential and Buyer shall have no obligation with respect to
any such Proprietary Information that:

             (i)           at the time of disclosure was already known to Buyer
                           other than through this transaction, free of
                           restriction as evidenced by documentation in Buyer's
                           possession;

             (ii)          is or becomes publicly known through publication,
                           inspection of a product, or otherwise, and through no
                           negligence or other wrongful act of Buyer;

             (iii)         is received by Buyer from a Third Party without
                           similar restriction and without breach of any
                           agreement;

             (iv)          to the extent it is independently developed by Buyer;
                           or

             (v)           is, subject to Section 6.2(c), required to be
                           disclosed under applicable Law or judicial process.

         (c) If Buyer (or any of its Affiliates) is requested or required (by
oral question, interrogatory, request for information or documents, subpoena,
civil investigative demand or similar process) to disclose any of Seller's
Proprietary Information, Buyer will promptly notify Seller of such request or
requirement and will cooperate with Seller such that Seller may seek an
appropriate protective order or other appropriate remedy. If, in the absence of
a protective order or the receipt of a waiver hereunder, Buyer (or any of its
Affiliates) is in the written opinion of Buyer's counsel required to disclose
the Proprietary Information, Buyer (or its Affiliate) may disclose only so much
of the Proprietary Information to the party compelling disclosure as is required
by Law. Buyer will exercise its (and will cause its Affiliates to exercise
their) reasonable commercial efforts to obtain a protective order or other
reliable assurance that confidential treatment will be accorded to such
Proprietary Information.

         (d) Except to the extent that disclosure thereof is required under
accounting, stock exchange or Federal Securities Laws disclosure obligations,
the terms and conditions of this Agreement, and all attachments and amendments
hereto and thereto shall be considered Proprietary Information protected under
this Article 6. Notwithstanding anything in this Article 6 to the contrary, in
the event that any such Seller's Proprietary Information is also subject to a
limitation on disclosure or use contained in another written agreement between
Buyer and Seller (including but not limited to, the Intellectual Property
Agreement) that is more restrictive than the limitation contained in this
Article 6, then the limitation in such agreement shall supersede this Article 6.
Notwithstanding anything in this Article 6 to the contrary, Buyer shall be
permitted to disclose the terms and conditions of this Agreement, and all
attachments and amendments hereto and thereto, and copies thereof, to its
Affiliates and to its and their respective officers, directors and employees and
professional advisors, in each case, who have a need to know such information
for the purposes of discharging their duties to Buyer and its Affiliates, and to
its lenders and investment dealers where required to


                                     - 40 -

do so under binding agreements with such Persons; provided, however, that Buyer
shall require all such Persons to maintain the confidentiality of any such
information in accordance with the terms hereof and Buyer shall remain
responsible to Seller for the actions of such parties with respect to such
information.

time within five (5) Business Days following the date on which the last of the
conditions specified in Article 8 to be satisfied or waived has been satisfied
or waived, or at such other place or time or on such other date as Seller and
Buyer may agree upon in writing (such date and time being referred to herein as
the "Closing Date").

7.4      CONTEMPORANEOUS EFFECTIVENESS

         All acts and deliveries prescribed by this Article 7, regardless of
chronological sequence, will be deemed to occur contemporaneously and
simultaneously on the occurrence of the last act or delivery required by this
Article, and none of such acts or deliveries will be effective until the last of
the same has occurred.

7.5      RISK OF LOSS FOR PURCHASED ASSETS

         From the date hereof to the Effective Time on the Closing Date, the
Purchased Assets shall be and remain at the risk of Seller. If prior to the
Effective Time on the Closing Date, any of such Purchased Assets are destroyed
or damaged by fire or any other casualty or shall be appropriated, expropriated
or seized by Governmental Body or other lawful authority, Buyer shall not be
required to complete the purchase of such Purchased Asset and shall not be
required to pay to Seller the portion of the Purchase Price attributed to such
Purchased Asset. In the event that the relevant Purchased Asset has not been
destroyed or appropriated, expropriated or seized but merely damaged and Buyer
elects to complete the purchase of such asset, the Purchase Price shall be
reduced by an amount mutually agreed by the parties or, if mutually agreed to by
the parties, Buyer shall pay the full Purchase Price therefor and any proceeds
of insurance net of all proven expenses incurred and paid by Seller to obtain
payment of such insurance proceeds, shall be paid to Buyer, if previously
received, or assigned to Buyer, in either case, as at the Effective Time on the
Closing Date.

                  Adverse Effect.

                  such representations and warranties were made at and as of the
                  Closing Date, except to the extent that such representations
                  and warranties are made as of a specified date, in which case

9.3      GENERAL AGREEMENT TO INDEMNIFY

         (a) Seller and Buyer shall indemnify, defend and hold harmless the
other party hereto, any Affiliate thereof, and any director, officer or employee
of such party or Affiliate thereof (each an "INDEMNIFIED PARTY") from and
against any and all claims, actions, suits, proceedings, liabilities,
obligations, losses, and damages, amounts paid in settlement, interest, costs
and expenses (including reasonable attorney's fees, court costs and other
out-of-pocket expenses incurred in investigating, preparing or defending the
foregoing) (collectively, "LOSSES") incurred or suffered by any Indemnified
Party to the extent that the Losses arise by reason of, or result from (i) the
failure of any representation or warranty of such party contained in this
Agreement to have been true in all material respects when made and as of the
Closing Date except as expressly provided otherwise in Section 8.2(a) or 8.3(a),
or (ii) the breach by such party of any covenant or agreement of such party
contained in this Agreement to the extent not waived by the other party.

         (b) Seller further agrees to indemnify and hold harmless Buyer from and
against any Losses incurred by Buyer arising out of, resulting from, or relating
to: (i) the Excluded Liabilities; (ii) Buyer's waiver of any applicable Bulk
Sales Laws; (iii) any claim, demand or liability for Taxes imposed on Buyer for
which Seller is responsible pursuant to Section 2.9; (iv) any claims of any
Business Employee employed by Buyer in connection with any Benefit Plan of
Seller or such Business Employee's employment with Seller accruing prior to and
including the Closing Date; (v) any event occurring or any condition existing at

rise to any liability under, any Environmental Law; (vi) any presence or any
release, spill, emission, discharge, leak, disposal, leaching or migration into

                                                    CONFIDENTIAL TREATMENT
                                                    REQUESTED.

Section 2.9; and (iii) any medical, health or disability claims of any
Transferred Employee, for claims for expenses incurred on or before the close of
business on the Closing Date which are not presented on a reasonably timely
basis to Seller by such Transferred Employee for payment or reimbursement in
accordance with the terms of the applicable Benefit Plan of Seller due to fault
of Buyer.

         (d) Amounts payable in respect of the parties' indemnification
obligations shall be treated as an adjustment to the Purchase Price. Buyer
and Seller agree to cooperate in the preparation of a supplemental Asset
Acquisition Statement as required by Section 5.3 and Treasury Reg. Section
1.1060-1T(e) as a result of any adjustment to the Purchase Price pursuant to
the preceding sentence. Whether or not the Indemnifying Party (as defined
below) chooses to defend or prosecute any Third-Party Claim (as defined in
Section 9.4(a)) both parties hereto shall cooperate in the defense or
prosecution thereof and shall furnish such records, information and
testimony, and attend such conferences, discovery proceedings, hearings,
trials and appeals, as may be reasonably requested in connection therewith or
as provided in Section 5.1.

         (e) The amount of the Indemnifying Party's liability under this
Agreement shall be determined taking into account any applicable insurance
proceeds actually received by, and other savings, including Tax savings, that
actually reduce the overall impact of the Losses upon, the Indemnified Party.
The indemnification obligations of each party hereto under this Article 9 shall
inure to the benefit of the directors, officers and Affiliates of the other
party hereto on the same terms as are applicable to such other party.

         (f) The Indemnifying Party's aggregate liability for all claims made
under (i) Section 9.3(a) hereof (other than with respect to breaches of
covenants relating to environmental or occupational health and safety matters),
(ii) Section 9.3(a) of the Columbus APA (other than with respect to breaches of
covenants relating to environmental or occupational, health and safety matters),
and (iii) Section 47.2 of the Supply Agreement shall be subject to the following
limitations: (i) the Indemnifying Party shall have no liability for such claims
until the aggregate amount of the Losses incurred shall exceed ***
dollars (US$***), in which case the Indemnifying Party shall be liable
only for the portion of the Losses exceeding *** dollars
(US$***), and (ii) the Indemnifying Party's aggregate liability for all such
claims (whether made under one or more of Section 9.3(a) hereof, Section 9.3(a)
of the Columbus APA or Section 46.2 of the Supply Agreement) shall not exceed
*** dollars (US$***). The Indemnified Party may not make a
claim for indemnification under Section 9.3(a) for breach by the Indemnifying
Party of a particular representation or warranty after the expiration of the
survival period specified in Section 9.2.

         (g) The Indemnifying Party's liability for all claims (excluding those
made under Section 9.3(a) which shall be governed by Section 9.2(f) and
excluding all claims made under Section 9.3(b)(v), (vi) or (vii) with respect to
environmental or occupational health and safety matters), shall be subject to
the following limitation: the Indemnifying Party shall have no liability for
such claims until the aggregate amount of the Losses incurred shall


                                     - 46 -

                          LUCENT TECHNOLOGIES/CELESTICA
<PAGE>


exceed one million dollars (US$1,000,000) (the "Threshold Amount"), in which
case the Indemnifying Party shall be liable for all Losses including the
Threshold Amount.

         (h) The indemnification provided in this Article 9 shall be the sole
and exclusive remedy after the Closing Date for damages available to the parties
to this Agreement for breach of any of the terms, conditions, representations or
warranties contained herein or any right, claim or action arising from the
transactions contemplated by this Agreement; PROVIDED, HOWEVER, this exclusive
remedy for damages does not preclude a party from bringing an action for
specific performance or other equitable remedy to require a party to perform its
obligations under this Agreement or any Collateral Agreement.

         (i) Notwithstanding anything contained in this Agreement to the
contrary, no party shall be liable to the other party for indirect, special,
punitive, exemplary or consequential loss or damage (including any loss of
revenue or profit) arising out of this Agreement, PROVIDED, HOWEVER, the
foregoing shall not be construed to preclude recovery by the Indemnified Party
in respect of Losses directly incurred from Third Party Claims. Both parties
shall use reasonable efforts to mitigate their damages.

         (j) The rights to indemnification under Section 9.3 shall not be
subject to set-off for any claim by the Indemnifying Party against any
Indemnified Party, whether or not arising from the same event giving rise to
such Indemnified Party's claim for indemnification.

9.4      GENERAL PROCEDURES FOR INDEMNIFICATION

         (a) The Indemnified Party seeking indemnification under this Agreement
shall promptly notify the party against whom indemnification is sought (the
"INDEMNIFYING PARTY") of the assertion of any claim, or the commencement of any
action, suit or proceeding by any Third Party, in respect of which indemnity may
be sought hereunder and will give the Indemnifying Party such information with
respect thereto as the Indemnifying Party may reasonably request, but failure to
give such notice shall not relieve the Indemnifying Party of any liability
hereunder (unless such failure prevents the Indemnifying Party from effectively
contesting the claim in respect of which indemnification is sought). The
Indemnifying Party shall have the right, but not the obligation, exercisable by
written notice to the Indemnified Party within thirty (30) days of receipt of
notice from the Indemnified Party of the commencement of or assertion of any
claim, action, suit or proceeding by a Third Party in respect of which indemnity
may be sought hereunder (a "THIRD-PARTY CLAIM"), to assume the defense and
control the settlement of such Third-Party Claim that (i) involves (and
continues to involve) solely money damages, or (ii) involves (and continues to
involve) claims for both money damages and equitable relief against the
Indemnified Party that cannot be severed, where the claims for money damages are
the primary claims asserted by the Third Party and the claims for equitable
relief are incidental to the claims for money damages.

         (b) The Indemnifying Party or the Indemnified Party, as the case may
be, shall have the right to participate in (but not control), at its own
expense, the defense of any Third-Party Claim that the other is defending, as
provided in this Agreement.

                          LUCENT TECHNOLOGIES/CELESTICA
<PAGE>


         (c) The Indemnifying Party, if it has assumed the defense of any
Third-Party Claim as provided in this Agreement, shall not consent to a
settlement of, or the entry of any judgment arising from, any such Third-Party
Claim without the Indemnified Party's prior written consent (which consent shall
not be unreasonably withheld) unless such settlement or judgment relates solely
to monetary damages. The Indemnifying Party shall not, without the Indemnified
Party's prior written consent, enter into any compromise or settlement that (i)
commits the Indemnified Party to take, or to forbear to take, any action, or
(ii) does not provide for a complete release by such Third Party of the
Indemnified Party. The Indemnified Party shall have the sole and exclusive right
to settle any Third-Party Claim, on such terms and conditions as it deems
reasonably appropriate, to the extent such Third-Party Claim involves equitable
or other non-monetary relief against the Indemnified Party, and shall have the
right to settle any Third-Party Claim involving money damages for which the
Indemnifying Party has not assumed the defense pursuant to this Section 9.4 with
the written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed.

         (d) In the event an Indemnified Party shall claim a right to payment
pursuant to this Agreement, such Indemnified Party shall send written notice of
such claim to the Indemnifying Party. Such notice shall specify the basis for
such claim. As promptly as possible after the Indemnified Party has given such
notice, and subject to the limitations set forth in Section 9.3, the Indemnified
Party and the Indemnifying Party shall establish the merits and amount of such
claim by mutual agreement, or, if necessary, by arbitration in a manner
reasonably determined by mutual agreement of such parties.

9.5      BREACH OF REPRESENTATIONS RESULTING IN LIMITATION OF OBLIGATIONS UNDER
THE SUPPLY AGREEMENT

         To the extent Buyer is unable to perform any of its obligations under
the Supply Agreement as a result of Seller failing to provide to Buyer
Proprietary Information in breach of Section 3.4(c) or 3.12(c) hereof, then
Buyer shall be relieved of such obligations under the Supply Agreement during
the period of time that the breach of Section 3.4(c) or 3.12(c), as the case may
be, remains uncured, and Buyer's failure to perform such obligations shall not
affect any applicable measure of Buyer's performance under the Supply Agreement,
including performance related to delivery under the Supply Agreement, and Seller
shall not assert any of its rights and remedies under the Supply Agreement
against Buyer as a result of such non-performance.

10.      MISCELLANEOUS PROVISIONS

10.1     NOTICES

         All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given upon receipt if (i) mailed by certified

other express carrier, fee prepaid, (iii) sent via facsimile with receipt
confirmed, or (iv) delivered personally, addressed as follows or to such other
