The Other 365 Contract List may be updated from time to time after the date hereof to reflect any additional Other 365 Contract that the Purchaser may designate as a Designated Other 365 Contract or remove any previously designated Designated Other 365 Contract prior to the applicable Final Contract Designation Date.

2.1.6 Assignment of Non-365 Contracts.

(a) Non-365 Contracts

(i) Section 2.1.6(a)(i) of the Sellers Disclosure Schedule sets forth a list (as may be updated and/or amended from time to time, the “Non-365 Customer Contract List”) of all Sellers’ Customer Contracts other than 365 Customer Contracts (the “Non-365 Customer Contracts”), which the relevant Seller will assign to the Purchaser or a Designated Purchaser at Closing. The Non-365 Customer Contract List shall be updated after the date hereof with all 365 Customer Contracts entered into by the Sellers in the Ordinary Course between the date hereof and the Closing Date.

(iv) The Purchaser shall not have the right to amend the Other Non-365 Contract List after the applicable Final Contract Designation Date without the prior written consent of the Main Sellers.

(b) Real Estate Leases

(i) Section 2.1.6(b)(i) of the Sellers Disclosure Schedule sets forth a list prepared by the Sellers (the “Real Estate Lease List”) of all real estate used in the conduct of the Acquired Business, whether located in the United States or in any other jurisdiction, except as otherwise covered under the EMEA Asset Sale Agreement, and subject to leases, subleases, space licenses or other agreements permitting a Seller to occupy real property, including an indication of which of the related properties have been made available to the Purchaser for either a Sublease or, as described in Section 5.16, a post-closing transitional license (the “Available Real Estate Leases”).

(ii) Section 2.1.6(b)(ii) of the Sellers Disclosure Schedule sets forth a list of the Available Real Estate Leases with respect to which (x) the Purchaser has elected to have the relevant Seller enter into a Sublease (as defined in Section 5.24) with the Purchaser or a Designated Purchaser at Closing (the “Subleased Real Estate Leases”), in accordance with and subject to the terms of the relevant lease, with each such Sublease to have a term to expire as specified in Section 5.24; or (y) the Purchaser has elected to have the relevant Seller enter into a license agreement (as contemplated by Section 5.16) with the Purchaser or a Designated Purchaser at Closing. Prior to the applicable Final Contract Designation Date, the list of Subleased Real Estate Leases and the list of designated licenses may be updated to reflect the designation or removal of Available Real Estate Leases.

(iii) After the applicable Final Contract Designation Date, the Purchaser shall have no right to designate additional Available Real Estate Leases for entry into a Sublease with or license to the Purchaser or Designated Purchaser or to remove any Available Real Estate Lease which has or shall have previously been designated by the Purchaser for sublease under this Section 2.1.6(b), without the prior written consent of the Main Sellers;

(iv) It is further understood and agreed that the Purchaser shall be obligated to enter into Subleases under all Subleased Real Estate Leases.

(c) Subject to Section 2.1.6(d), Section 2.1.10, Section 5.13 and the receipt of any required Consent, all the Non-365 Customer Contracts and the Designated Other Non-365 Contracts in effect as of the Closing shall be assigned to the Purchaser or a Designated Purchaser at Closing pursuant to Section 2.1.1(c) and the Purchaser or a Designated Purchaser shall enter into a Sublease at Closing pursuant to Section 5.24 with the relevant Seller under each of the Subleased Real Estate Leases in effect as of the Closing.

(d) The Parties shall, and the Purchaser shall cause the Designated Purchasers to, use their reasonable best efforts to obtain all Consents required to permit the assignment to the Purchaser (or, if specified by the Purchaser, to a Designated Purchaser) of the 365 Customer Contracts, the Designated Other 365 Contracts, the Non-365 Customer Contracts and the Designated Other Non-365 Contracts in force as of the Closing Date, and the entry into the Subleases; provided, however, that, except as expressly provided in Section 2.1.7(c) with respect to Cure Costs for Customer Contracts, the Sellers shall be under no obligation to compromise any right, asset or benefit or to expend any amount or incur any Liability in seeking such Consents. For greater certainty, the failure to obtain any or all of such Consents shall not in itself entitle the Purchaser to terminate this Agreement or fail to complete the transactions contemplated hereby or entitle the Purchaser to any adjustment to the Purchase Price.

2.1.7 Cure Costs; Adequate Assurance.

(a) On or prior to the date hereof, the Sellers shall have delivered Section 2.1.7(a)(i) of the Sellers Disclosure Schedule to the Purchaser, which Schedule contains with respect to each Other 365 Contract and Other Non-365 Contract, the Sellers’ good faith estimate of the amount of Cure Costs.

(b) To the extent that the assumption and assignment of any 365 Customer Contract entails the payment of any Cure Cost, NNI shall, or shall cause the relevant U.S. Debtor to, pay or otherwise provide for payment of such Cure Cost as required by the U.S. Bankruptcy Code and provided in the U.S. Sale Order. To the extent that assumption and assignment of any Designated Other 365 Contract entails the payment of any Cure Cost (the “Other 365 Cure”) as required by the U.S. Bankruptcy Code and provided in the U.S. Sale Order, the Purchaser shall be responsible for payment of such Cure Cost; provided, that any such payment by the Purchaser shall not entitle the Purchaser to any adjustment to the Purchase Price or any reimbursement or indemnification from the Sellers on account of payments made by the Purchaser pursuant to this section 2.1.7(b).

(c) To the extent that assignment to the Purchaser or a Designated Purchaser of any Non-365 Customer Contract entails the payment of any Cure Cost, the relevant Main Sellers shall, or shall cause the relevant Seller to, pay such amounts directly to such counterparty in a manner agreed between such Main Seller or such relevant Seller, as applicable, and such counterparty or ordered by a court of competent jurisdiction. To the extent that assignment to the Purchaser or a Designated Purchaser of any Assigned Contract other than a Non-365 Customer Contract or an Assumed and Assigned Contract entails the payment of Cure Costs (the

“Other Non-365 Cure,” and together with the Other 365 Cure, the “Other Cure”), the Purchaser shall be responsible for payment of such Cure Cost to such contracting party in a manner agreed between the Purchaser, the Sellers and such contracting party or ordered by a court of competent jurisdiction; provided, that any such payment shall not entitle the Purchaser to any adjustment to the Purchase Price or any reimbursement or indemnification from the Sellers on account of payments made by the Purchaser pursuant to this section 2.1.7(c).

(d) The Purchaser and the Sellers agree to carry out the actions set forth in Exhibit 2.1.7(d).

(e) To the extent that entry into a Sublease with the Purchaser or a Designated Purchaser of any Subleased Real Estate Lease or the license of any Available Real Estate Lease pursuant to Section 2.1.6(b) entails the payment of Cure Costs, the Purchaser shall pay its pro-rata share (based on the ratio of the rentable square footage of the premises subject to such sublease or license to the overall rentable square footage of the premises demised under such Subleased Real Estate Lease or Available Real Estate Lease) of such Cure Costs directly to such contracting party in a manner agreed between the Purchaser and such contracting party or ordered by a court of competent jurisdiction. The Main Seller or relevant Seller shall be responsible to pay the remainder of such Cure Costs in a manner agreed between such Main Seller or such relevant Seller, as applicable, and such counterparty or ordered by a court of competent jurisdiction. In the case of any Cure Costs relating to any Available Real Estate Lease, the Sellers and the Purchaser shall agree as to the amounts required to be paid to the relevant landlord prior to payment by either the Sellers or the Purchaser with respect to the same.

(f) Prior to the hearing before the U.S. Bankruptcy Court to approve the assumption and assignment of the Assumed and Assigned Contracts, the Purchaser shall provide adequate assurance of its and the relevant Designated Purchasers’ future performance under each Assumed and Assigned Contract to the parties thereto (other than the U.S. Debtors) in satisfaction of section 365(f)(2)(B) of the U.S. Bankruptcy Code and to the extent required by the U.S. Sale Order.

(g) The Parties shall, and shall cause the Other Sellers and the Designated Purchasers, as applicable, to, use reasonable best efforts to obtain all Consents required to permit the assignment to the Purchaser (or, if specified by the Purchaser, a Designated Purchaser) of the Assigned Contracts and the entry into Subleases; provided, however, that the Sellers shall be under no obligation to seek any such Consent prior to the completion of the Auction or to compromise any right, asset or benefit or to expend any amount or incur any Liability or provide any other consideration in seeking such Consents other than filing and application fees to Government Entities and payment of Cure Costs for which such Party is responsible pursuant to Section 2.1.7, and, provided, further, that the failure to obtain any or all of such Consents shall not entitle the Purchaser to terminate this Agreement or fail to complete the transactions contemplated hereby or entitle the Purchaser to any adjustment to the Purchase Price.

2.1.8 Local Sale Agreements. Subject to the terms and conditions hereof, to the extent necessary to effect the Closing on the terms hereof, the relevant Sellers shall, and the Purchaser shall, and shall cause the relevant Designated Purchasers to, enter into such agreements or instruments, including bills of sale and/or assignment and assumption agreements

(the “Local Sale Agreements”), providing for (i) the sale, transfer, assignment or other conveyance to the Purchaser and/or relevant Designated Purchasers, in accordance with the requirements of applicable local Law, of any Assets located in the countries where such Local Sale Agreements are required, and (ii) the assumption by the Designated Purchasers of any Assumed Liability that the Purchaser intends to allocate to them. In the event of a conflict between this Agreement and any Local Sale Agreement, this Agreement shall prevail. The Parties further agree that no allocation of Purchase Price and no amounts by way of valuation of the Assets, whether provisional, estimated or final, shall be included in any instruments of assignment and/or transfer, except as required by applicable Law.

2.1.9 EMEA Asset Sale Agreement. Except as otherwise set forth in Exhibit 5.25 hereto, none of the EMEA Sellers or the Joint Administrators shall assume, or be deemed to assume, any Liability whatsoever under this Agreement and nothing in this Agreement (except to the extent expressly incorporated into the EMEA Asset Sale Agreement) shall apply to, or govern, the sale, assignment, transfer, retention or assumption of assets, rights, properties or Liabilities of, or by, any EMEA Sellers or the Joint Administrators in any manner whatsoever. The only assets, rights, properties and Liabilities of the EMEA Sellers or the Joint Administrators that are being sold, assigned or transferred to, and assumed by, the Purchaser or the EMEA Designated Purchasers, and the terms and conditions thereof, and representations with respect thereto, are solely as expressly set forth in the EMEA Asset Sale Agreement. Neither the Purchaser nor any Designated Purchaser shall be entitled to make any claim under this Agreement, or assert any right hereunder, against any Person other than the Sellers.

2.1.10 Non-Assignable Assets. Notwithstanding anything in this Agreement to the contrary, if a Consent of a Third Party (including a Government Entity) has not been obtained on or prior to Closing, then, unless such Consent is subsequently obtained, this Agreement shall not constitute an agreement to sell, transfer or assign, directly or indirectly, any Asset or any obligation or benefit arising thereunder if an attempted direct or indirect sale, transfer, lease, sublease or assignment thereof, without such Consent (in each case, after taking into account the effect of the U.S. Sale Order, the Canadian Approval and Vesting Order, and any other order of a court of competent jurisdiction), would constitute a breach, default, violation or other contravention of Law or the rights of such Third Party or would be ineffective with respect to any party to a Contract concerning such Asset. For greater certainty, except as explicitly set forth in Article VIII, failure to obtain any such Consent shall not entitle the Purchaser to terminate this Agreement or fail to complete the transactions contemplated hereby or entitle the Purchaser to any adjustment of the Purchase Price, and the Main Sellers and the Purchaser shall each act in accordance with Section 5.13 hereof in relation to any Deferred Transfer Purchased Assets.

SECTION 2.2 Purchase Price.

2.2.1 Purchase Price. Pursuant to the terms and subject to the conditions set forth in this Agreement, in consideration of the purchase, sale, assignment and conveyance of the Sellers’ and EMEA Sellers’ right, title and interest in, to and under the Assets and the EMEA Assets, respectively, pursuant and subject to the terms hereof and pursuant and subject to the terms of the EMEA Asset Sale Agreement, respectively, and of the rights granted by certain

Sellers and the EMEA Sellers under the Intellectual Property License Agreement and the Trademark License Agreement, the Purchaser, on its own behalf and as agent for the Designated Purchasers, shall (x) assume and become obligated to pay, perform and discharge, when due, the Assumed Liabilities and the EMEA Assumed Liabilities and (y) pay to the Distribution Agent, as agent for the Sellers and the EMEA Sellers, an aggregate amount of cash equal to Sixty Five million dollars ($65,000,000) (the “Base Purchase Price”), as adjusted pursuant to Sections 2.2.2 and 2.2.3 (as so adjusted, the “Purchase Price”); provided, that for the avoidance of doubt, the Parties acknowledge that amounts of or in respect of VAT (as defined in the EMEA Asset Sale Agreement) and/or Transfer Taxes that are the responsibility of the Purchaser pursuant to Section 6.1 shall be paid directly to the Tax Authority or, to the relevant Seller, EMEA Seller or Joint Administrators for remittance to the applicable Tax Authority in the amount required to be paid to such Tax Authority in accordance with applicable Law, pursuant to and in accordance with the relevant provisions of this Agreement and the EMEA Asset Sale Agreement and shall not be paid to the Distribution Agent).

(i) the Base Purchase Price; minus

(ii) the amount, if any, by which the Estimated Closing Adjusted Net Working Capital Transferred is less than the Target Adjusted Net Working Capital Transferred; minus

(iii) the Estimated EMEA Downward Adjustment; minus

(iv) the excess (if any) of the Estimated Total Prepaid Revenue Transferred over the Target Total Prepaid Revenue Transferred; minus

(v) an amount equal to the Estimated Pre-Close Employment Payments.

2.2.3 Post-Closing Purchase Price Adjustment.

2.2.3.1 Closing Statement; Dispute Resolution

(a) As promptly as practicable (and in any event within sixty (60) days after the Closing), the Purchaser shall deliver to the Main Sellers and the EMEA Sellers a written statement (the “Closing Statement”) that shall contain their final calculation of (i) the Adjusted Net Working Capital Transferred as of the Closing Date (the “Closing Adjusted Net Working Capital Transferred”), (ii) all EMEA Downward Adjustments as of the Closing (the “Closing EMEA Downward Adjustment”), (iii) the Total Prepaid Revenue Transferred as of the Closing Date (the “Closing Total Prepaid Revenue Transferred”), (iv) Pre-Close Employment Payments that the EMEA Sellers have failed to pay prior to the Closing as of the Closing (the “Closing Pre-Close Employment Payments”), (v) the final Purchase Price, and (vi) the amount payable by either Party pursuant to Section 2.2.3.2 as an adjustment to the Estimated Purchase Price. The Closing Statement shall be prepared in accordance with the Calculation Principles and the terms hereof. Throughout the periods during which the Closing Statement is being prepared and any disputes that may arise under this Section 2.2.3 are being resolved, the Main Sellers and the EMEA Sellers shall, promptly upon request, provide the Purchaser and its respective accountants reasonable access to the assets, books, records, documents, schedules and workpapers and personnel of the Acquired Business in connection with the preparation of the Estimated Closing Statement.

(b) If the Main Sellers and the EMEA Sellers disagree with the determination of the Closing Statement, the Main Sellers and the EMEA Sellers shall notify the Purchaser of such disagreement within sixty (60) days after delivery of the Closing Statement (such notice, the “Disagreement Notice”). The Disagreement Notice shall set forth, in reasonable detail, any disagreement with, and any requested adjustment to, the Closing Statement. If the Main Sellers and the EMEA Sellers fail to deliver the Disagreement Notice by the end of such sixty- (60-) day period, the Main Sellers and the EMEA Sellers shall be deemed to have accepted as final the Closing Statement delivered by the Purchaser. Matters included in the calculations in the Closing Statement to which the Main Sellers and the EMEA Sellers do not object in the Disagreement Notice shall be deemed accepted by the Main Sellers and the EMEA Sellers and shall not be subject to further dispute or review. Throughout the periods during which the Closing Statement is being prepared and any disputes that may arise under this Section 2.2.3 are being resolved, the Purchaser shall, promptly upon request, provide the Main Sellers and the EMEA Sellers and their respective accountants reasonable access to the assets, books, records, documents, schedules, workpapers and personnel of the Purchaser in connection with the Main Sellers’ and the EMEA Sellers’ and their respective accountants’ review of the Closing Statement. The Purchaser, the Main Sellers and the EMEA Sellers shall negotiate in good faith to resolve any disagreement with respect to the Closing Statement, and any resolution agreed to in writing by the Purchaser and the Main Sellers and the EMEA Sellers shall be final and binding upon the Parties.

(c) If the Purchaser and the Main Sellers and the EMEA Sellers are unable to resolve any disagreement as contemplated by Section 2.2.3.1(b) within fourteen (14) days after delivery of a Disagreement Notice by the Main Sellers and the EMEA Sellers, either the Main Sellers, the EMEA Sellers or the Purchaser may appoint the Accounting Arbitrator, on behalf of

all Parties and the EMEA Sellers, to resolve such disagreement. The Accounting Arbitrator’s determination shall be based only on the written submissions by the Main Sellers, the EMEA Sellers and the Purchaser and not upon any independent review by the Accounting Arbitrator. The Primary Parties and NNUK shall instruct the Accounting Arbitrator and the Accounting Arbitrator shall consider only those items and amounts set forth in the Closing Statement as to which the Main Sellers, the EMEA Sellers and the Purchaser have not resolved their disagreement. With respect to each such item, the decision of the Accounting Arbitrator shall be the amount claimed by the Main Sellers and the EMEA Sellers, the amount claimed by the Purchaser, or an amount between the amount claimed by the Main Sellers and the EMEA Sellers and the amount claimed by the Purchaser. The Main Sellers, NNUK and the Purchaser shall instruct, and they shall use their reasonable best efforts to cause, the Accounting Arbitrator to deliver to the Primary Parties and NNUK, as promptly as practicable (and in no event later than thirty (30) days after his or her appointment), a written report setting forth the resolution of any such disagreement determined in accordance with the terms of this Agreement. Such report and the Closing Statement, as adjusted thereby, shall be final and binding upon the Parties and the EMEA Sellers. Neither the Main Sellers, the EMEA Sellers nor the Purchaser shall have any ex parte communications or meetings with the Accounting Arbitrator regarding the subject matter hereof without the other Primary Parties’ prior consent. In the event the Accounting Arbitrator concludes that the Purchaser was correct as to a majority (by dollar amount) of the disputed items, then the Sellers and the EMEA Sellers shall pay the Accounting Arbitrator’s fees, costs and expenses. In the event the Accounting Arbitrator concludes that the Main Sellers and the EMEA Sellers were correct as to a majority (by dollar amount) of the disputed items, then the Purchaser shall pay the Accounting Arbitrator’s fees, costs and expenses.

(a) Prior to the date hereof, the Purchaser has delivered to NNI cash in the amount of $1.25 million ($1,250,000) (the “Good Faith Deposit”) to serve as earnest money under this Agreement and the EMEA Asset Sale Agreement.

2.2.6 Purchase Price Allocation.

(a) Except as otherwise required by applicable Law, the Parties and the EMEA Sellers shall (i) first allocate to the tangible Assets, the tangible EMEA Assets and the CIP Unbilled Accounts Receivable of the Acquired Business a proportion of the Purchase Price (and, to the extent properly taken into account under the applicable Tax Laws, the Assumed Liabilities and the EMEA Assumed Liabilities), equal to the net book value of such Assets and such EMEA Assets as of the Closing Date and (ii) then allocate the balance of the Purchase Price, as adjusted in clause (i) of this Section, to the intangible Assets and the intangible EMEA Assets.

(b) To the extent necessary to file Transfer Tax Returns, the Parties shall negotiate in good faith to determine an allocation of the Purchase Price, (and, to the extent properly taken into account under the applicable Tax Laws, the Assumed Liabilities and the EMEA Assumed Liabilities) among the Assets and the EMEA Assets in accordance with the principles of Section 1060 of the Code and the Treasury regulations promulgated thereunder and other applicable Tax Laws, which allocation shall be consistent with the principles of Section 2.2.6(a) (such allocation, a “Partial Allocation”). If the Parties do not reach agreement on a Partial Allocation after negotiating in good faith, the Partial Allocation shall be submitted to the Accounting Arbitrator, which shall prepare a final Partial Allocation; provided, however, that if a different Partial Allocation is required by a Government Entity (including for this purpose an allocation required, approved or authorized pursuant to a Bankruptcy Proceeding), then the Partial Allocation shall be modified as necessary to be consistent with the required allocation (but in all cases shall be consistent with the principles of Section 2.2.6(a) to the extent permitted by such Government Entity). Notwithstanding the preceding sentence, if the Parties have not reached agreement on the Partial Allocation and the Accounting Arbitrator has not submitted its determination on or before the date that a Transfer Tax Return is required to be filed with the relevant Tax Authority (giving effect to any valid extensions) pursuant to Section 6.7(b), then such Transfer Tax Return shall be timely filed in the manner that the Party with primary responsibility for filing such return reasonably determines and, upon receiving the Accounting Arbitrator’s later determination and to the extent permitted under applicable Law, the filing Party shall promptly file, or cause to be filed, an amended return in accordance therewith. The Parties agree (i) to be bound by the final Partial Allocation accepted by the Parties or prepared by the Accounting Arbitrator (as modified to be consistent with the allocation required by a Government Entity, as described above), as applicable, and (ii) to act in accordance with the allocations contained in such final Partial Allocation for all purposes relating to Transfer Taxes (including the preparation and filing of any Transfer Tax Returns). For purposes of this Section 2.2.6(b), the

term “Parties” shall include the EMEA Sellers to the extent any negotiations or agreement required hereunder concern Transfer Tax Returns.

SECTION 2.3 Closing.

2.3.1 Closing Date.

SECTION 2.4 Designated Purchaser(s).

(a) The Purchaser shall be entitled to designate, in accordance with the terms and subject to the limitations set forth in this Section 2.4, one or more Affiliates of the Purchaser to (i) purchase specified Assets (including specified Assigned Contracts), (ii) assume specified Assumed Liabilities, and/or (iii) employ identified Transferred Employees on and after the Closing Date (any Person that shall be properly designated by the Purchaser in accordance with this clause, a “Designated Purchaser”); it being understood and agreed, however, that any such right of the Purchaser to designate a Designated Purchaser is conditioned upon (y) such Designated Purchaser being able to perform the applicable covenants under Section 2.1.7 and Article VII and demonstrate satisfaction of the requirements of section 365 of the U.S. Bankruptcy Code (to the extent applicable), including the provision of adequate assurance for future performance with respect to the Assumed and Assigned Contracts and (z) any such designation not creating any Liability (including any Liability relating to Taxes other than Taxes for which the Purchaser is liable pursuant to Article VI) for the Sellers or their Affiliates that would not have existed had the Purchaser purchased the Assets, assumed the Assumed Liabilities and/or employed the Transferred Employees, and which Liability is not fully reimbursed by or on behalf of the Purchaser; provided, further, however, that the Sellers acknowledge and agree that each of Ericsson Inc., Ericsson Canada Inc., or Ericsson AB (each, a “Confirmed Designated Purchaser”) shall be deemed to satisfy the foregoing conditions and may be a Designated Purchaser. Subject to Section 6.2(c), if the designation of a Confirmed Designated Purchaser creates any Liability relating to Taxes for the Sellers or their Affiliates that would not have existed had the Purchaser purchased the relevant Assets, the Purchaser or the Designated Purchasers shall pay such additional amounts to the Sellers such that the total amount received by the applicable Sellers, after reducing such amount by the additional Liability relating to Taxes for the Sellers or their Affiliates created by the designation of such Confirmed Designated Purchaser, will equal the full amount such Seller would have received from the Purchaser had the designation not been made. No such designation shall relieve the Purchaser of any of its obligations hereunder. Any breach hereof by a Designated Purchaser shall be deemed a breach by the Purchaser. The Purchaser and each Designated Purchaser shall be jointly and severally liable for any obligations assumed by any of them hereunder.

(b) As soon as reasonably practicable and in no event later than twenty (20) days prior to the Closing Date, the Purchaser shall make the designation referenced in Section 2.4(a) by way of a written notice to be delivered to the Sellers; provided, however, that the Parties agree that such notice may be amended and/or updated by the Purchaser from time to time to the extent there is a relevant material change in the information provided by the Sellers with respect to the jurisdictions in which the Assets are located. Such notice shall, (x) for any Designated Purchasers other than the Confirmed Designated Purchasers, contain appropriate

information about the Designated Purchaser(s), including the legal name of the Designated Purchaser, the jurisdiction of incorporation or formation of the Designated Purchaser, the actual (and if there is any intention to change such residence on or prior to Closing proposed) jurisdiction of Tax residence of the Designated Purchaser and (y) (i) indicate in reasonable detail which Assets, Assumed Liabilities and Transferred Employees the Purchaser intends such Designated Purchaser(s) to purchase, assume and/or employ, as applicable, hereunder, (ii) include a signed counterpart or an accession agreement to this Agreement, in either case in a form reasonably acceptable to the Main Sellers, whereby such Designated Purchaser agrees to be bound by the terms of this Agreement and authorizing the Purchaser to act as such Designated Purchaser(s)’ agent for all purposes hereunder and (iii) for any Designated Purchasers other than the Confirmed Designated Purchasers, contain such reasonable evidence as the relevant Seller may reasonably require to demonstrate that any such designation will not (A) create any liability relating to Taxes for any Seller or any Affiliate thereof or any member of the Sellers’ group that would not have existed had the Purchaser purchased the relevant Asset, assumed the relevant Assumed Liability or employed the relevant Transferred Employee and (B) reduce the amount of consideration actually received by any Seller whether as a result of any deduction or withholding for or on account of Tax or otherwise, where such reduction would not have occurred had the purchase, assumption and/or employment (as relevant) been made by the Purchaser, in each of clauses (A) and (B) which cost is not fully reimbursed by the Purchaser or a Designated Purchaser at the Closing.

To the extent required by any Bankruptcy or other Laws, the Purchaser will be able to provide, at Closing or on such earlier date as is designated by the U.S. Bankruptcy Court, adequate assurance of its and/or the relevant Designated Purchasers’ future performance under each Assumed and Assigned Contract to the parties thereto (other than the U.S. Debtors) in satisfaction of section 365(f)(2)(B) of the U.S. Bankruptcy Code, and no other or further assurance will be necessary thereunder with respect to any Assumed and Assigned Contract.

(iv) no Seller, EMEA Seller or any other Person shall have or be subject to any liability to the Purchaser, any Designated Purchaser or any Affiliate or representative of the Purchaser or any Designated Purchaser resulting from the distribution to the Purchaser or any Designated Purchaser, or the Purchaser’s or any Designated Purchaser’s use, of the information referred to in Section 3.6(b)(ii);

For greater certainty, nothing herein shall require the items in the preceding sentence to be included in the Canadian Approval and Vesting Order or any endorsement thereof, notwithstanding that such provisions may be included in the form of the order set forth in Exhibit 5.2.1.

SECTION 5.3 Consultation; Notification.

(a) The Purchaser and the U.S. Debtors shall cooperate with prosecuting the U.S. Sale Motion, and obtaining entry of the U.S. Sale Order, and the U.S. Debtors shall deliver to the Purchaser prior to filing, and as early in advance as is practicable to permit adequate and reasonable time for the Purchaser and its counsel to review and comment, copies of all proposed pleadings, motions, notices, statements schedules, applications, reports and other material papers to be filed by the U.S. Debtors in connection with such motions and relief requested therein.

Each of the Parties hereby agrees to use its reasonable best efforts to obtain an expedited resolution of such appeal; provided, however, that, subject to the conditions set forth herein, nothing contained in this Section shall preclude the Parties from consummating, or permit the Parties not to consummate, the transactions contemplated hereby if the U.S. Sale Order shall have been entered and shall not have been stayed, modified, revised or amended, in which event the Purchaser and the relevant Designated Purchasers shall be able to assert the benefits of section 363(m) of the U.S. Bankruptcy Code and, as a consequence of which, such appeal shall become moot.

(d) If the Canadian Approval and Vesting Order or any other order of the Canadian Court relating to this Agreement shall be appealed by any Person (or a petition for certiorari or motion for rehearing, re-argument or stay shall be filed with respect thereto), the Canadian Debtors agree to take all reasonable steps, and use their reasonable best efforts to defend against such appeal, petition or motion, and the Purchaser agrees to cooperate in such efforts. Each of the Parties hereby agrees to use its reasonable best efforts to obtain an expedited resolution of such appeal; provided, however, that, subject to the conditions set forth herein, nothing in this Section shall preclude the Parties from consummating, or permit the Parties not to consummate, the transactions contemplated hereby if the Canadian Approval and Vesting Order shall have been entered and shall not have been stayed, modified, revised or amended.

SECTION 5.4 Pre-Closing Cooperation.

(a) Prior to the Closing, upon the terms and subject to the terms and conditions of this Agreement, in addition to any obligations pursuant to Section 5.5, each of the Parties shall use its reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable under applicable Law to consummate the transactions contemplated by this Agreement as soon as practicable and cause the fulfillment at the earliest practicable date of all of the conditions to the other Parties’ obligations to consummate the transactions contemplated by this Agreement, including: (i) the preparation and filing of all forms, registrations and notices required to be filed to consummate the Closing and the taking of such actions as are necessary to obtain any requisite Consent, provided, that the Sellers shall not be obligated to make any payment or deliver anything of value to any Third Party in order to obtain any Consent (other than filing and application fees to Government Entities, and payment of Cure Costs if responsible therefor pursuant to Section 2.1.7) and provided, further, that the Purchaser shall be obligated to cooperate with the Sellers in order to obtain any required Consents from landlords under any Subleased Real Estate Leases (to the extent consent is required) and to enter into Subleases, (ii) defending all lawsuits and other proceedings by or before any Government Entity challenging this Agreement or the consummation of the Closing, (iii) using reasonable efforts to cause to be

lifted or rescinded any injunction, decree, ruling, order or other action of any Government Entity that would prohibit, prevent, restrict or materially delay the consummation of the transactions contemplated by this Agreement, and (iv) cooperating in any reorganization of the Sellers that the Sellers consider necessary for the Sellers to facilitate the transactions contemplated hereby, any such reorganization to occur on or prior to the Closing Date. With respect to all supply Contracts related to the Business, after the entry of the U.S. Sale Order, and in respect of the Canadian Debtors, after the entry of the Canadian Approval and Vesting Order, the Sellers shall (i) at the Purchaser’s request to the extent permitted by Law (including any applicable Antitrust Laws), send a letter substantially in the form set forth in Exhibit 5.4(a) to each of the counterparties to such Contracts, as identified in writing by the Purchaser to the Main Sellers, (ii) provide to the Purchaser such contact information as is reasonably requested by the Purchaser with respect to the counterparties to such Contracts and (iii) more generally, to facilitate an orderly transition at Closing, work with outside counsel on the prosecution of pending patent applications and maintenance of existing patents. For greater certainty, the obligations in this Section 5.4(a) do not include an obligation to negotiate, agree to or accept any form of remedy, condition, undertaking or divestiture with any Government Entity; provided, however, that nothing in this Section 5.4(a) shall limit the obligations of the Purchaser or any Designated Purchaser set forth in Section 5.5.

(b) Each Primary Party shall promptly notify the other Primary Parties of the occurrence, to such Party’s Knowledge or knowledge, as applicable, of any event or condition, or the existence, to such Party’s Knowledge or knowledge, as applicable, of any fact, that would reasonably be expected to result in any of the conditions to any other Primary Party’s obligation to effect the Closing set forth in Article VIII not being satisfied.

(c) NNC and NNL shall execute, at or within a reasonable amount of time after Closing, upon the Purchaser’s request, such documents as reasonably requested by the Purchaser and as contemplated or otherwise permitted under the Patent Cross-License Agreements listed on Section 4.5(g)(iii) of the Sellers Disclosure Schedule in order to provide a sublicense to the Business (to the extent permitted thereunder) or trigger any spin-off right thereunder, such that the Business may continue to be licensed or sublicensed thereunder, all in accordance with the relevant Section of each such Patent Cross-License Agreement that permits NNC or NNL to sublicense or spin off the license granted to NNC or NNL thereunder to a divested business unit or product line. To the extent that any Patent Cross-License Agreement listed on Section 4.5(g)(iii) of the Sellers Disclosure Schedule, including, without limitation, (i) the Patent Cross License Agreement, effective as of June 16, 2006, between Ciena Corporation and NNL; (ii) the Patent Cross License Agreement, effective as of July 17, 2006, among Microsoft Corporation, NNC and NNL; and (iii) the License Agreement, effective as of January 1, 2001, between International Business Machines Corporation and NNC, contains a limitation on the number of times the relevant Seller may exercise any sublicense or spin off rights thereunder and such rights have not been exhausted prior to the date hereof, the Sellers agree that they shall not exhaust any such rights they may have between the date hereof and the Closing in a manner that would render this Section 5.4(c) ineffective. Notwithstanding the foregoing, the Sellers shall be under no obligation to execute any such documents prior to the completion of the Auction or to expend any amount (other than as directly resulting from the execution of relevant documents), incur any Liabilities or provide any other consideration in complying with their obligations under this section 5.4(c).

SECTION 5.5 Antitrust and Other Regulatory Approvals.

(a) In furtherance and not in limitation of the provisions of Section 5.4, each of the Parties agrees to prepare and file as promptly as practicable following the U.S. Sale Hearing and the Canadian Sale Hearing all necessary documents, registrations, statements, petitions, filings and applications for the Mandatory Regulatory Approvals, the Trade Approvals and any other Consent of any other Government Entities either required or that the Primary Parties mutually and reasonably agree are advisable to satisfy the condition set forth in Section 8.1(a) as expeditiously as possible.

(b) If a Primary Party or any of its Affiliates receives a request for information or documentary material from any Government Entity with respect to this Agreement or any of the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement), then such Primary Party shall make, or cause to be made, as soon as reasonably practicable and after consultation with the other Primary Parties, an appropriate response in compliance with such request.

(c) Each Primary Party shall keep the other Primary Parties apprised of the status of matters relating to the completion of the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement) and work cooperatively in connection with obtaining the Mandatory Regulatory Approvals and the Trade Approvals of each applicable Government Entity, including, to the extent permitted by Law or Government Entity:

(i) cooperating with each other in connection with the filings required under the applicable Antitrust Laws, Trade Laws or any Laws regulating foreign investment of any jurisdiction in connection with the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement) and each Mandatory Regulatory Approval and Trade Approval and liaising with each other in relation to each step of the procedure before the relevant Government Entities and as to the contents of all communications with such Government Entities. In particular, to the extent permitted by Law or Government Entity, no Party will make any notification in relation to the transactions contemplated hereunder without first providing the Primary Parties with a copy of such notification in draft form (subject to reasonable redactions or limiting such draft, or parts thereof, on an outside-counsel only basis where appropriate) and giving such Primary Parties a reasonable opportunity to discuss its content before it is filed with the relevant Government Entities, and such first Party shall consider and take account in good faith of all reasonable comments timely made by the Primary Parties in this respect; provided, however, that no Party shall be required to provide the other Party with such portions of notifications or submissions that would jeopardize any attorney-client or other legal privilege (it being understood, however, that the Parties shall cooperate in any reasonable efforts and requests that would enable otherwise required disclosure to the other Parties to occur without so jeopardizing privilege); provided, further, that a Party may provide such portions of notifications or submissions solely to the other Party’s outside counsel pursuant to a common interest agreement and non-disclosure agreement,

each to be negotiated by the Parties in good faith, if such Party determines, acting reasonably, that the provision to the other Party of such portions of notifications or submissions could reasonably be expected to have a material adverse effect upon it if the transactions contemplated by this Agreement are not consummated;

(ii) furnishing to the other Primary Parties all information within its possession that is required for obtaining the Mandatory Regulatory Approvals or Trade Approvals, or required for any application or other filing to be made by the other Party pursuant to the applicable Antitrust Laws, Trade Laws or any Laws regulating foreign investment of any jurisdiction in connection with the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement); provided, however, that (a) no such information shall be required to be provided by a Party if it determines, acting reasonably, that, such information is material and competitively sensitive or that the provision of such information could reasonably be expected to have a material adverse effect upon it if the transactions contemplated by this Agreement were not completed or that the provision of such information would jeopardize any attorney-client or other legal privilege (it being understood, however, that the parties shall cooperate in any reasonable efforts and requests that would enable otherwise required disclosure to the other parties to occur without so jeopardizing privilege), and (b) in any such case the Purchaser and the Main Sellers shall cooperate with a view to establishing a mutually satisfactory procedure for providing such information directly to the Government Entity requiring or requesting such information, and the relevant Main Seller or the Purchaser or the relevant Designated Purchaser required to provide such information shall provide it directly to such Government Entity requiring or requesting such information;

(iii) promptly notifying each other of any substantive communications from or with any Government Entity with respect to the transactions contemplated by this Agreement and/or by the EMEA Asset Sale Agreement and ensuring that each of the Parties is entitled to attend any meetings with, or other appearances before, any Government Entity with respect to the transactions contemplated by this Agreement and the EMEA Asset Sale Agreement; and

(iv) consulting and cooperating with each other in connection with all analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to the Mandatory Regulatory Approvals, the applicable Antitrust Laws or any Laws regulating foreign investment of any jurisdiction, in connection with the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement).

(d) In addition, subject to any limitations set forth in Section 5.5(e), the Purchaser shall, and shall cause each of the Designated Purchasers to, use its reasonable efforts to satisfy (or cause the satisfaction of) the conditions precedent to the Purchaser’s obligations hereunder as set forth in Section 8.1(a) to the extent the same is within its control and to take, or cause to be taken, all other action and to do, or cause to be done, all other things necessary,

proper or advisable under all applicable Laws to consummate the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement), including using its reasonable efforts to make all required filings and obtain all Mandatory Regulatory Approvals, and any other Consent of a Government Entity required to be obtained in order for the Parties to consummate the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement).

(e) Subject to the proviso below, the obligations of the Purchaser pursuant to Section 5.5(d) shall include committing, and causing the Designated Purchasers to commit, to any and all undertakings, divestitures, licenses or hold separate or similar arrangements with respect to their respective assets or the Assets and/or the EMEA Assets or conduct of business arrangements or terminating any and all existing relationships and contractual rights and obligations as a condition to obtaining any and all Consents from any Government Entity necessary to consummate the transactions contemplated hereby and/or by the EMEA Asset Sale Agreement, including taking any and all actions necessary in order to ensure the receipt of the necessary Consents and Mandatory Regulatory Approvals; provided, however, that none of the Purchaser, the Designated Purchasers, or the EMEA Designated Purchasers are under any obligation under this Agreement or the applicable provisions of the EMEA Asset Sale Agreement, in respect of obtaining the Mandatory Regulatory Approvals or otherwise, to commit, or cause the Designated Purchasers or the EMEA Designated Purchaser to commit, to any undertakings, divestitures, licenses or hold separate or similar arrangements with respect to their respective assets or the Assets and/or the EMEA Assets or conduct of business arrangements or terminate any and all existing relationships and contractual rights and obligations or take any other action where to do so could reasonably be expected to be materially adverse to the business, financial condition, or prospects of the Purchaser, any Designated Purchaser, any EMEA Designated Purchaser, or the Business or Assets being acquired pursuant to this Agreement and the EMEA Asset Sale Agreement.

(f) For the avoidance of doubt, the covenants under this Section 5.5 shall not apply to any action, effort, filing, Consent, proceedings, or other activity or matter relating to the Bankruptcy Courts, the Bankruptcy Proceedings and/or the Bankruptcy Consents.

SECTION 5.6 Pre-Closing Access to Information.

(a) The Main Sellers shall, and shall cause the Other Sellers (other than the EMEA Debtors or EMEA Sellers) to, (i) give the Purchaser and its authorized representatives, upon reasonable advance notice and during regular business hours, reasonable access to (x) all books, records, personnel, officers and other facilities and properties of the Acquired Business and (y) only after the entry of the U.S. Sale Order and the Canadian Approval and Vesting Order, all product documentation and design specifications of the Acquired Business, including access to certain managerial Employees designated by the Sellers, who have knowledge of the skills and competencies of Employees relative to the Business and will provide such information to the Purchaser and Human Resources personnel designated by the Sellers who can provide information relevant to the Purchaser otherwise complying with the Purchaser’s obligations pursuant to ARTICLE VII, (ii) permit the Purchaser and its representatives to make such copies and inspections thereof, upon reasonable advance notice and during regular business hours, as

the Purchaser may reasonably request, (iii) cause the officers of the Sellers to furnish the Purchaser with such financial, business and operating data and other information with respect to the Acquired Business as is regularly prepared in the Ordinary Course that the Purchaser may from time to time reasonably request, (iv) without limiting the generality of subsections (i), (ii) and (iii), deliver to the Purchaser no later than ten (10) Business Days following the end of each fiscal quarter a report reflecting any changes to the headcount of the Business since the previous fiscal quarter; provided, however, that (A) any such access shall be conducted at the Purchaser’s expense, in accordance with Law (including any applicable Antitrust Law and Bankruptcy Law), at a reasonable time, under the supervision of the Sellers’ personnel and in such a manner as to maintain confidentiality and not to unreasonably interfere with the normal operations of the Business or the other businesses of the Sellers and their Affiliates, (B) except pursuant to Section 7.1.1 and Section 5.6(e), the Sellers will not be required to provide to the Purchaser access to or copies of any Employee Records, other than as provided in Section 5.6(e). If any requested documentation and information includes what can reasonably be considered competitively sensitive information relating to sales, marketing or pricing of the Sellers products or services, such information shall be shared with any employees or representatives of the Purchaser who are designated by the Purchaser and reasonably agreed upon by the Sellers, who reasonably require access to such information for any reasonable business purpose related to the acquisition of the Business by the Purchaser and who have executed the Clean Team Confidentiality Agreement, provided, however, that where such documentation or information relates to pricing or other material competitive terms offered to any customer of the Business, the employees of the Purchaser shall not have access to such information unless they are not involved in making decisions regarding pricing or other material competitive terms for a competing business to the Business, and if the transaction does not close, agree not to be employed in such a role for an agreed-upon minimum period of time.

(b) Notwithstanding anything contained in this Agreement or any other agreement between the Purchaser and the Sellers executed on or prior to the date hereof (other than Section 6.5), the Sellers shall not have any obligation to make available to the Purchaser or its representatives, or provide the Purchaser or its representatives with, (i) any Tax Return filed by the Sellers or any of their Affiliates or predecessors, or any related material or (ii) more generally, any information if, in the good faith opinion of the Sellers, making such information available would (A) result in the loss of any attorney-client or other legal privilege or (B) cause the Sellers to be found in contravention of any applicable Law, or contravene any fiduciary duty or agreement existing on the date hereof (including any confidentiality agreement to which the Sellers or any of their Affiliates are a party), it being understood that the Sellers shall cooperate in any reasonable efforts and requests that would enable otherwise required disclosure to the Purchaser to occur without so jeopardizing privilege or contravening such Law, duty or agreement.

(c) To the extent not already made available to the Purchaser, the Purchaser’s employees or the Purchaser’s representatives (including its outside counsel), in order to facilitate the Purchaser’s entry into new supply arrangements effective as of the Closing, upon request the Sellers shall make available to the Purchaser, its employees and representatives (including its outside counsel) unredacted copies of all Contracts relating to the Business with suppliers of the Business, or in the case of Non-Exclusive Supply Contracts, unredacted copies of any portion thereof that are applicable to the Business (other than pricing/cost information or other

competitively sensitive information the sharing of which Sellers or their representatives reasonably determine may violate applicable Law), reasonably promptly following the date of such request (or in the event that such Contract is subject to confidentiality restrictions promptly following the receipt of any required consent which the Sellers will cooperate with the Purchaser to obtain as promptly as practicable). So long as the Purchaser is the Successful Bidder, the Sellers shall provide any competitively sensitive information redacted in accordance with the preceding sentence (including, but not limited to, Customer Contracts and Bundled Contracts) promptly following the later of the entry of the U.S. Sale Order, Canadian Approval and Vesting Order and the receipt of Antitrust Approvals; provided, that access to Bundled Contracts shall be limited to unredacted copies of any portion of any Bundled Contract that relates to the Business including any portion that relates to the Business and other businesses of the Sellers. Any access to Contracts pursuant to this Section 5.6(c) shall be subject to the available resources of the Sellers and availability of the Contracts and shall not interfere with the normal operations of the business of the Sellers. Any such disclosure shall be made to any employees or representatives of the Purchaser who are designated by the Purchaser, who reasonably require access to such information for any reasonable business purpose related to the acquisition of the Business by the Purchaser and who have executed the applicable addendums to the Clean Team Confidentiality Agreement; provided, however, that employees of the Purchaser shall not have access to such information unless they are not involved in making decisions regarding pricing or the other material competitive terms offered to any customer of a competing business to the Business.

(d) Following the later of the entry of the U.S. Sale Order, the Canadian Approval and Vesting Order and the receipt of Antitrust Approvals, the Sellers and the Purchaser shall cooperate (consistent with applicable Laws and any confidentiality restrictions requiring consent of Third Parties) in developing a strategy with respect to transitioning customers of the Business to the Purchaser, including a plan for the engagement of customers of the Business by the Purchaser. Commencing reasonably in advance of the expected Closing Date, the Sellers shall make introductions of the Purchaser to such customers with whom the Purchaser does not have an existing customer relationship, by, subject to applicable Law, participating in telephone calls and meetings with such customers.

(e) Within five (5) Business Days following the entry of the U.S. Sale Order and, in respect of the Canadian Debtors, the Canadian Approval and Vesting Order, the Sellers will provide the following additional information with respect to each of the Employees whose information was provided in Section 4.11(b) of the Sellers Disclosure Schedule: (i) full name and (ii) work e-mail address. Following the expiration of the Offer Consideration Period, provided, that the Purchaser provides the Sellers with proof that an Employee has consented in the Offer to its release and, if applicable, transfer across geographical boundaries, the Sellers will provide the Purchaser with the following additional information with respect to such Employees as permitted under applicable Law and within five (5) Business Days following the receipt by the Sellers of such proof: the HR SAP data elements (excluding data related to protected status under applicable Law) with respect to each such Employee, including payroll information where applicable from vendors, with such data elements to be updated by the Sellers ten (10) Business Days prior to the Closing Date. Following the completion of the Auction, and upon the Purchaser being named the Successful Bidder, upon the Purchaser’s reasonable request, the Sellers promptly will provide the Purchaser’s benefit service provider with census data with respect to gender, birthday, salary and zip code (if applicable) of the Employees (without

individually identifying any Employee and excluding any Employee unique identifier) for the sole purpose of calculating projected employee benefit costs and on the condition that census data is not disclosed to the Purchaser or any other Person.

SECTION 5.7 Public Announcements. Subject to (i) the provisions of Section 7.4(a) with respect to communications and announcements to the Employees and the employees of the Purchaser and the Designated Purchasers and the last sentence of this Section 5.7 and (ii) the Parties’ disclosure obligations imposed by Law (including any obligations under any Bankruptcy Laws) or stock exchange regulations, the Parties shall (a) cooperate with each other in the development and distribution of all news releases, other public information disclosures and announcements, including announcements and notices to customers, suppliers and Employees, with respect to this Agreement, or any of the transactions contemplated by this Agreement and the other Transaction Documents and (b) not issue any such announcement or statement prior to consultation with, and the approval of, the Primary Parties (such approval not to be unreasonably withheld or delayed); provided, that approval shall not be required where a Party determines, based on advice of counsel and after consultation with the Primary Parties, that such disclosure is required by Law or stock exchange regulations. For the avoidance of doubt, this Section 5.7 shall not impose any restrictions in addition to those set forth in the Confidentiality Agreement with respect to non-public communications between the Purchaser and its direct shareholders. The Parties shall comply with the provisions of Exhibit 5.7.

SECTION 5.8 Further Actions. From and after the Closing Date, each of the Parties shall execute and deliver such documents and other papers and take such further actions as may reasonably be required to carry out the provisions of this Agreement and give effect to the transactions contemplated herein, including the execution and delivery of such assignments, deeds and other documents (including Local Sale Agreements) as may be necessary to transfer any Assets as provided in this Agreement; provided, that subject to Section 2.1.6(d), Section 2.1.7(f), Section 5.4, Section 5.5 and Section 5.25, neither the Purchaser nor the Sellers shall be obligated to make any payment or deliver anything of value to any Third Party (other than filing and application fees to Government Entities and payment of Cure Costs for which such Party is responsible pursuant to Section 2.1.7) in order to obtain any Consent to the transfer of Assets or the assumption of Assumed Liabilities. If following the Closing, any Seller receives or becomes aware that it holds any asset, property or right which constitutes an Asset, then such Seller shall promptly transfer such asset, property or right to the Purchaser for no additional consideration in accordance with Section 2.1.1 (provided, that any costs or expenses incurred by the Sellers in connection with such transfer shall be borne by the Purchaser).

SECTION 5.9 Conduct of Acquired Business. The Sellers covenant that except as (i) the Purchaser may approve otherwise in writing (such approval not to be unreasonably withheld or delayed), (ii) set forth in Section 5.9 of the Sellers Disclosure Schedule, (iii) otherwise expressly contemplated or permitted by this Agreement or another Transaction Document, including Section 5.4, (iv) required by Law (including any applicable Bankruptcy Law or by order of a Bankruptcy Court entered as of the date hereof), or (v) relates solely to Excluded Assets or Excluded Liabilities in a manner that does not materially and

adversely affect the Acquired Business, Assets or Assumed Liabilities, the Sellers shall (A) conduct the Acquired Business and maintain the Owned Equipment and other Assets in the Ordinary Course, (B) use commercially reasonable efforts in the context of the Bankruptcy Proceedings and taking into account employee and customer attrition to continue operating the Business as a going concern and to maintain the business organizations of the Business intact, and (C) abstain from any of the following actions:

(a) sell, lease or otherwise dispose of a material portion of the Assets or any Assets material to the Acquired Business (other than sales of Inventory in the Ordinary Course);

SECTION 5.10 Transaction Expenses. Except as otherwise provided in this Agreement or the other Transaction Documents to which the Sellers are parties, each of the Purchaser and the Sellers shall bear its own costs and expenses (including brokerage commissions, finders’ fees or similar compensation, and legal fees and expenses) incurred in connection with this Agreement, the other Transaction Documents and the transactions contemplated hereby and thereby.

SECTION 5.11 Confidentiality.

(a) The Parties acknowledge that the Confidentiality Agreement (including all amendments thereto) and the Clean Team Confidentiality Agreement (including all addenda thereto) remain in full force and effect in accordance with their respective terms, which are incorporated herein by reference, and the Parties agree to be bound thereby in the same manner and to the same extent as if the terms had been set forth herein in full, except that the Sellers shall be at liberty to disclose the terms of this Agreement: (i) to the extent required by Law or any Action in respect of the Acquired Business, (ii) to any court, any liquidator or any member of any committee of creditors, Tax Authority or Government Entity, (iii) in connection with any auction process approved by the Bankruptcy Court, (iv) to show appropriate figures in their administration records, accounts and returns, or (v) subject to entering into a confidentiality agreement with the relevant Third Party, in connection with acquiring, merging or otherwise combining, or being acquired by, or selling all or part of their assets to any Third Party (whether in a single transaction or a series of related transactions and whether structured as an acquisition of assets, securities or otherwise); provided, that, with respect to information and data relating exclusively to the Business, the Purchaser’s and the Purchaser’s Representatives’ confidentiality obligations under this Section 5.11, the Confidentiality Agreement (including all amendments thereto) and the Clean Team Confidentiality Agreement (including all addenda thereto) shall terminate after the Closing Date. The Purchaser’s confidentiality obligations with respect to other Confidential Information relating to the Business and/or Assets under the Confidentiality Agreement and the Clean Team Confidentiality Agreement (including as incorporated herein) shall terminate after the Closing Date except with respect to the terms and conditions of any Patent Cross-License Agreement or Omitted Patent Cross-License Agreement listed in Section 4.5(g)(iii) of the Sellers Disclosure Schedule (but not with respect to the existence of such Patent Cross-License Agreements and Omitted Patent Cross-License Agreements and the Transferred Patents to which they relate); provided, that the Purchaser shall treat such other Confidential Information with at least the same degree of care and confidentiality as it would treat its own confidential information of similar sensitivity were it in the Sellers’ position. The Purchaser acknowledges that in the course of attempting to sell the Assets and the Business, one or more of the Sellers have entered into several confidentiality agreements with Third Parties in respect of information relating to the Assets and the Business and has disclosed such information to certain of those Third Parties.

(b) For purposes of this Agreement, “Confidential Information” consists of all competitively sensitive information and data related to the Sellers, the Business, the Assets (including Transferred Intellectual Property and competitively sensitive Business Information existing as of the Closing Date), the Purchaser or its Affiliates that is not, in each case, already available to the public (it being agreed that disclosure of Confidential Information to prospective purchasers, their representatives and other Persons affiliated with the sale process of the Business shall not be public disclosure thereof). Nothing herein or in the other Transaction Documents shall be construed as precluding, prohibiting, restricting or otherwise limiting the ability of the Sellers, the Sellers’ Affiliates or their respective representatives to (i) disclose the terms of any of the Transaction Documents to any court or to any liquidator or in connection with any auction process approved by a Bankruptcy Court and show appropriate figures in their administration records, accounts and return; (ii) exercise or enforce any of their rights, or perform any obligations under this Agreement or the other Transaction Documents, including the Transition Services Agreement and the Intellectual Property License Agreement, (iii) make permitted disclosures under Section 5.7; (iv) make any disclosures that are required by applicable Law; (v)

own, use or disclose Confidential Information that is not exclusive to the Business to the extent necessary to (in the reasonable judgment of the Sellers) operate the other business segments of the Sellers or their Affiliates or otherwise engage in any manner in any business activities unrelated to the Business; (vi) use Confidential Information to the extent necessary to perform any Seller Contracts not assigned to the Purchaser; (vii) share information to the extent reasonably necessary to allocate the purchase proceeds from the sale of the Assets; or (viii) make customary disclosures, subject to customary confidentiality agreements, regarding Confidential Information that is not exclusive to the Business and is primarily related to other business segments of the Sellers in connection with acquiring, merging or otherwise combining with, or being acquired by, or selling all or part of their assets to, any Person (whether in a single transaction or a series of related transactions or whether structured as an acquisition of assets, securities or otherwise).

(c) As promptly as reasonably practicable, and in no event more than thirty (30) days, after the Closing Date, the Sellers shall deliver to the Purchaser copies of correspondence, notices, filings, prosecution files, dockets, certifications and other documents relating to the filing, prosecution, issuance and renewal of the Business Registered IP, provided that all items to be delivered hereunder shall be delivered solely by remote telecommunication to the extent the Purchaser may so request. Without limiting the generality of the foregoing, within thirty (30) days of Closing, the Sellers shall and shall cause their Affiliates to, instruct their current attorneys and agents to deliver to the Purchaser, or attorneys designated by Purchaser, any and all records in the possession of such attorneys and agents relating to the prosecution of any applications, registrations and renewals of any Business Registered IP.

SECTION 5.12 Certain Payments or Instruments Received from Third Parties. To the extent that, after the Closing Date, (a) the Purchaser and/or any Designated Purchaser receives any payment or instrument that is for the account of a Seller according to the terms of any Transaction Document or relates primarily to any business or business segment of the Sellers other than the Acquired Business, the Purchaser shall, and shall cause the Designated Purchasers to, promptly deliver such amount or instrument to the relevant Seller, and (b) any of the Sellers receives any payment that is for the account of the Purchaser or any of the Designated Purchasers according to the terms of any Transaction Document or relates primarily to the Acquired Business, the Sellers shall, and shall cause the other Sellers to promptly deliver such amount or instrument to the Purchaser or the relevant Designated Purchaser, as applicable. All amounts due and payable under this Section 5.12 shall be due and payable by the applicable Party in immediately available funds, by wire transfer to the account designated in writing by the relevant Party. Notwithstanding the foregoing, each Party hereby undertakes to use reasonable efforts to direct or forward all bills, invoices or like instruments to the appropriate Party.

SECTION 5.13 Non-Assignable Contracts and Other Assets.

(a) To the extent that any Assigned Contract or any Seller Consent is not capable of being assigned under Section 365 of the U.S. Bankruptcy Code (or, if inapplicable, pursuant to other applicable Laws or the terms of such Contract or Consent) to the Purchaser or a

Designated Purchaser at the Closing, or that any Subleases cannot be entered into (A) without the Consent of the issuer thereof or the other party thereto, the master landlord or any Third Party (including a Government Entity) or (B) without the Sellers’ and their Affiliates’ compromising any right, asset or benefit or expending any amount or incurring any Liability or providing any other consideration other than as provided in Section 2.1.7 (collectively, the “Non-Assignable Contracts”), this Agreement will not constitute an assignment thereof, or an attempted assignment, nor shall any Sublease be entered into under any Non-Assignable Contract, unless and until any such Consent is obtained, including any Consents obtained following Closing; provided, however, that the Sellers will use reasonable best efforts (without incurring any Third Party costs) to (i) cooperate with the Purchaser in any commercially reasonable arrangement to provide the Purchaser the same interest, benefits, rights and Liabilities under any such Non-Assignable Contracts as the applicable Seller had immediately prior to the Closing and the Purchaser and the Sellers shall use reasonable best efforts to enter into one or more mutually agreed Subcontract Agreements, and (ii) facilitate the Purchaser’s negotiation with the other party to each Non-Assignable Contract that is a license of Intellectual Property to provide the Purchaser the same interest, benefits and rights under any such Non-Assignable Contracts as the applicable Seller had immediately prior to the Closing (including that the Sellers shall request such Third Party’s Consent if so requested by the Purchaser); provided, that there shall be no obligation on Sellers or their Affiliates to compromise any material right, asset or benefit or expend any amount or incur any Liability. As between the Sellers and the Purchaser (or the relevant Designated Purchaser), such Non-Assignable Contracts described above shall be deemed to be assigned or subleased, as the case may be, and the Purchaser (or the relevant Designated Purchaser) shall perform all obligations and covenants thereunder. Notwithstanding the foregoing sentences, (w) nothing in this Section 5.13 shall require any Seller to renew, modify or amend any Non-Assignable Contract once it has expired, (x) any efforts required of the Sellers pursuant to this paragraph shall be strictly on an interim basis and in no event shall such efforts or arrangements be required after the earlier of the (1) the date on which the Transition Services Agreement either expires or is terminated in accordance with its terms or (2) the effective date of a plan under Chapter 11 of the U.S. Bankruptcy Code confirmed by any of the U.S. Debtors pursuant to an order of the U.S. Bankruptcy Court (such date, the “Contract Rejection Date”), (y) the Sellers shall have the right, any time on or after the Contract Rejection Date, to exercise any right to terminate, reject or repudiate any Non-Assignable Contract, and (z) to the extent not prohibited, be of an administrative nature only, without any substantive function, and shall be carried out by employees of the Sellers under the Transition Services Agreement. In addition to performing and holding the Sellers harmless from any Liabilities under any Non-Assignable Contract, the Purchaser or the Designated Purchaser, as applicable, shall reimburse the relevant Seller for any direct, incremental and out-of-pocket costs and indemnify and hold each Seller harmless from and against all Liabilities, incurred or asserted, as a result of any actions taken pursuant to this Section 5.13. The Parties acknowledge that the fact that any Contract constitutes a Non-Assignable Contract shall not (i) constitute a breach of any covenant hereunder, (ii) entitle the Purchaser to terminate this Agreement or (iii) result in any reduction of the Purchase Price payable hereunder. Any Non-Assignable Contract assigned pursuant to the terms of this Section 5.13 shall, when assigned, constitute an Assigned Contract hereunder from and after such date.

(b) For the purposes of this Agreement (including Section 5.13(a) and all representations and warranties of the Sellers contained herein), the relevant Sellers shall be

deemed to have obtained all required Consents in respect of the assignment of any Assumed and Assigned Contract if, and to the extent that, pursuant to the U.S. Sale Order, the Sellers are authorized to assume and assign to the Purchaser or the Designated Purchasers such Seller Contract pursuant to section 365 of the U.S. Bankruptcy Code and any applicable Cure Cost has been satisfied as provided in Section 2.1.7.

(c) If and to the extent that sale to the Purchaser or any Designated Purchaser of any Assets pursuant to Section 2.1.1 would be a violation of applicable Law or require any Consent or the approval of any Government Entity or the fulfillment of any condition that cannot be fulfilled by the Purchaser prior to the Closing, then, to the extent permitted by applicable Law, including any Antitrust Laws, and unless the Purchaser shall otherwise agree, the sale to the Purchaser or any Designated Purchaser of such Asset shall be, without any further action by any Party hereto, automatically deferred and any sale of such Asset pursuant to Section 2.1.1 or otherwise shall be null and void until such time as all such violations of applicable Law are eliminated, such Consents or approvals of Government Entities are obtained and such conditions are fulfilled. Any such Asset shall be deemed a “Deferred Transfer Purchased Asset.”

(d) If and to the extent that the allocation to the Purchaser or any Designated Purchaser, and the Purchaser or any Designated Purchaser becoming responsible for, any Assumed Liabilities pursuant to Section 2.1.3 or otherwise would be a violation of applicable Law or require any Consent or the approval of any Government Entity, then, to the extent permitted by applicable Law, including any Antitrust Laws and unless the Parties shall otherwise agree, the allocation to the Purchaser or any of its Subsidiaries of, and the Purchaser or any such Designated Purchaser becoming responsible for, such Assumed Liability shall, without any further action by any party, be automatically deferred and any allocation or responsibility for such Assumed Liability pursuant to Section 2.1.3 or otherwise shall be null and void until such time as all violations of applicable Law are eliminated, such Consents or approvals of Government Entities are obtained. Any such Assumed Liability shall be deemed a “Deferred Transfer Assumed Liability.”

(e) With respect to any Deferred Transfer Purchased Asset or any Deferred Transfer Assumed Liability, insofar as it is reasonably possible and permitted under applicable Law, including any Antitrust Laws, (i) the Sellers shall, following the Closing, hold such Deferred Transfer Purchased Asset for the use and benefit of the Purchaser and its Subsidiaries (at the expense of the Purchaser) and (ii) in addition to performing and holding the Sellers harmless from any Deferred Transfer Assumed Liability, the Purchaser shall, or shall cause its applicable Subsidiary to, pay or reimburse the Sellers for all direct, incremental and out-of-pocket amounts paid or costs incurred in connection with the retention of such Deferred Transfer Assumed Liability. The Sellers shall, insofar as reasonably possible and to the extent permitted by applicable Law, including any Antitrust Laws, hold and treat such Deferred Transfer Purchased Asset in the Ordinary Course and take such other actions as may be reasonably requested by the Purchaser in order to place the Purchaser or any of its Subsidiaries, insofar as permissible under applicable Law, including any Antitrust Laws, and reasonably possible, in the same position as if such Deferred Transfer Purchased Asset had been sold to the Purchaser or a Designated Purchaser at the Closing and so that, to the extent possible, all the benefits and burdens relating to such Deferred Transfer Purchased Asset, including possession, use, risk of loss, potential for gain, and dominion, control and command over such Deferred Transfer

Purchased Asset, are to inure from and after the Closing to the Purchaser or its applicable Subsidiary entitled to the receipt of such Deferred Transfer Purchased Asset.

(f) If and when the violations of applicable Law are eliminated and such consents, approvals and/or conditions of Government Entities are obtained, the absence or non-satisfaction of which caused the deferral of transfer of any Deferred Transfer Purchased Asset pursuant to Sections 5.13(c), the sale of the applicable Deferred Transfer Purchased Asset shall be effected in accordance with and subject to the terms of this Agreement. If and when the violations of applicable Law are eliminated and such consents, approvals and/or conditions of Government Entities are obtained, the absence or non-satisfaction of which caused the deferral of the allocation of any Deferred Transfer Assumed Liability to the Purchaser or any Designated Purchaser pursuant to Sections 5.13(d), the allocation of the applicable Deferred Transfer Assumed Liability to the Purchaser or any Designated Purchaser shall be effected in accordance with and subject to the terms of this Agreement.

(g) Notwithstanding any other provision of this Section 5.13, any efforts required of the Sellers pursuant to this Section 5.13 in respect of Deferred Transfer Purchased Asset shall (i) be subject to receipt of adequate compensation in respect of all direct, incremental and out-of-pocket costs and expenses in respect of or related to such arrangement, (ii) be strictly on an interim basis and in no event required to continue after the expiration of the term of the Transition Services Agreement, (iii) to the extent not prohibited, be of an administrative nature only, without any substantive function, and be carried out by employees of the Sellers under the Transition Services Agreement. In no event shall the Sellers be under any obligation to compromise any right, asset or benefit or to expend any amount or incur any Liability in order to comply with its obligations under this Section 5.13 for which they are not reimbursed (other than filing and application fees to Government Entities and payment of Cure Costs for which the Sellers are responsible pursuant to Section 2.1.7) and the failure to transfer any Deferred Transfer Purchased Asset or any Deferred Transfer Assumed Liability shall not entitle the Purchaser to terminate this Agreement, not to complete the transactions contemplated hereby or reduce the Purchase Price payable hereunder.

SECTION 5.14 Bundled Contracts.

(a) Section 5.14(a) of the Sellers Disclosure Schedule lists each Contract that the Sellers have entered into prior to the date hereof providing for the sale or provision of Products or Services and the sale or provision of other products or services of the Sellers or their Affiliates (including any such Contract that has been unbundled prior to the date hereof) (as such list may be amended or supplemented pursuant to Section 5.14(c)) (each, a “Bundled Contract”). Subject to applicable Law, each of the Purchaser and the Sellers shall, and the Purchaser shall cause any relevant Designated Purchaser, as applicable, to, use its reasonable best efforts to, at least fifteen (15) Business Days prior to the Closing Date, enter into arrangements with the counterparty to each Bundled Contract to amend such Bundled Contract so as to delete all obligations and Liabilities therefrom as they relate to the Products and the Services and enter into a new Contract (effective as of, and conditioned upon the occurrence of, the Closing) with the applicable customer and which only relates to Products and Services on substantially the same terms and conditions as are in effect for the sale or provision of Products

and/or Services under the Bundled Contract or as otherwise acceptable to Purchaser, in which event such new Contract shall be deemed to be an Assigned Contract; provided, however, that the Sellers shall be under no obligation to compromise any right, asset or benefit or to expend any amount or incur any Liability in obtaining such arrangements and the failure to enter into such arrangements with respect to any Bundled Contract shall not entitle the Purchaser to terminate this Agreement, not to complete the transactions contemplated hereby or reduce the Purchase Price payable hereunder; . To the extent permitted by the terms of such Bundled Contract and applicable Law, each of the Sellers and the Purchaser shall notify the other Party if any customer has contacted such Party with regard to the matters set forth in this Section 5.14 and shall keep such other Party reasonably informed regarding the content of any discussions with the customer. For the avoidance of doubt, nothing in this Section 5.14(a) shall restrict the Sellers from taking any actions with respect to Bundled Contracts otherwise permitted pursuant to Section 5.9, including any amendments thereof. The Sellers shall, and shall cause their respective Affiliates (to the extent practicable) to, not enter into any Bundled Contracts after the date hereof.

(b) Subject to applicable Law and the terms of such Bundled Contracts, for those Bundled Contracts for which the arrangements mentioned in Section 5.14(a) could not be entered into fifteen (15) Business Days prior to the Closing Date, (i) the relevant Seller shall, until the Contract Rejection Date, to the extent requested by the Purchaser, use its reasonable best efforts to facilitate the entry by the Purchaser or the relevant Designated Purchaser and the other party to each such Bundled Contract into a new Contract that only relates to the Business, including by making available those employees who are responsible for managing the customer relationships with the customers of such Bundled Contracts (to the extent reasonably practicable and to the extent such employees remain in the employ of the Sellers), reasonably cooperating with the Purchaser to jointly contact each counterparty to such Bundled Contracts by making such contacts (by phone or in person) as may be reasonably requested by the Purchaser and by sending a joint letter, in form and substance satisfactory to each of such Seller and the Purchaser notifying the counterparty to each such Bundled Contract of the transactions and requesting the counterparty to agree to amend such Bundled Contract after the Closing Date or (ii) the relevant Seller and the Purchaser shall use their reasonable best efforts to cooperate in any commercially reasonable arrangement to provide the Purchaser or a Designated Purchaser, as applicable, with the same interest, benefits, rights and Liabilities (including obligations relating to warranties and Known Product Defects (as defined in the Nortel Accounting Principles) as the applicable Seller had immediately prior to the Closing under any such Bundled Contract insofar as they relate to the Acquired Business, including by entering into Subcontract Agreements with respect to the portion of any such Bundled Contract that relates to the Acquired Business (the “MSS Portion”) on the same terms and conditions as those set forth in the MSS Portion of the relevant Bundled Contract; provided, that (w) nothing in this Section 5.14 shall require any Seller to renew any Bundled Contract once it has expired, (x) the Sellers shall have the right after the Contract Rejection Date to exercise any right to terminate, reject or repudiate any Bundled Contract and (y) the Sellers shall be under no obligation with respect to the MSS Portion of any Bundled Contract that is, or is to be, subcontracted hereunder to compromise any right, asset or benefit or to expend any amount or incur any Liability in order to comply with its obligations under this sentence for which they are not reimbursed (other than filing and application fees to Government Entities, and payment of any Cure Costs for which the Sellers are responsible pursuant to Section 2.1.7) and the failure to enter into such arrangements with respect to any Bundled

Contract shall not entitle the Purchaser to terminate this Agreement, not to complete the transactions contemplated hereby or reduce the Purchase Price payable hereunder. Notwithstanding the foregoing, the Sellers shall not take any action to terminate or reject any Bundled Contract, or take any action or fail to take any action that would permit the other party to any Bundled Contract to terminate such Bundled Contract, in each case, prior to the Contract Rejection Date.

(c) Prior to the Closing Date, the Sellers shall, subject to the prior written consent of the Purchaser (such consent not to be unreasonably withheld), be entitled to update and/or supplement from time to time the list of Bundled Contracts entered into prior to the date hereof by written notices to the Purchaser promptly after discovering any such Bundled Contracts; provided, that no such update or supplement shall be made within five (5) Business Days of Closing, and provided further that the Sellers shall use commercially reasonable efforts to update the list of Bundled Contracts as soon as commercially practicable.

SECTION 5.15 Post-Closing Assistance for Litigation.

(a) Except with respect to Tax matters, after the Closing, the Purchaser shall, upon the reasonable request of the Sellers, and at no cost to the Sellers (other than reimbursement of direct, incremental and out-of-pocket expenses), make the Transferred Employees reasonably available at reasonable times and cooperate in all reasonable respects with the Sellers and their Affiliates in the preparation for, and defense of, any lawsuit, arbitration, Claim or other Action (whether disclosed or not disclosed in the Sellers Disclosure Schedule) filed or claimed against the Sellers or any of their Affiliates or any of the respective agents, directors, officers and employees of the Sellers and their Affiliates, whether currently pending or asserted in the future, concerning the operation or conduct of the Acquired Business prior to the Closing Date; provided, however, that the obligations of the Purchaser or its Affiliates hereunder shall only extend to the employees of such Purchaser or Purchaser’s Affiliates as of the date such employees are to be made available and shall not apply to former employees of such Purchaser or Purchaser’s Affiliates that have been terminated prior to such date.

(b) Except with respect to Tax matters, after the Closing, the Sellers and their Affiliates shall, upon the reasonable request of the Purchaser, and at no cost to the Purchaser or its Affiliates (other than reimbursement of direct, incremental and out-of-pocket expenses), make employees of the Sellers or their Affiliates and all necessary documents available at reasonable times and cooperate in all reasonable respects with the Purchaser and its Affiliates in the preparation for, and defense of, any lawsuit, arbitration or other Action filed or claimed against the Purchaser or any of its Affiliates or any of the respective agents, directors, officers and employees of the Purchaser and its Affiliates, whether currently pending or asserted in the future, concerning the operation or conduct of the Acquired Business prior to the Closing Date; provided, however, that the obligations of the Sellers or their Affiliates hereunder shall only extend to the employees of such Sellers or Sellers’ Affiliates as of the date such employees are to be made available and shall not apply to former employees of such Sellers or Sellers’ Affiliates that have been terminated prior to such date.

SECTION 5.16 Tangible Asset Removal.

(a) The Purchaser shall, and shall cause the relevant Designated Purchasers to, at the Purchaser’s sole cost and expense, within five (5) Business Days after the Closing Date, relocate all tangible Assets and the Purchaser’s activities from all premises owned or leased by the Sellers or their Affiliates after the Closing (other than any premises to be occupied by the Purchaser or any Designated Purchasers after the Closing Date pursuant to the provisions of a Sublease) with the Sellers’ cooperation, and in each case where the Purchaser or a Designated Purchaser fails to so relocate, the Purchaser shall compensate the Sellers for 200% of the Sellers’ actual, out-of-pocket rent and other occupancy costs with respect to such premises, plus 200% of the charges that the Sellers would impose on a subtenant in such premises for all services provided to such premises by a Seller or a third party services provider, and indemnify the Sellers for any liability or damages resulting from the Purchaser’s or a Designated Purchaser’s continued occupancy from one (1) Business Day after the Closing Date through the date upon which the Purchaser or such Designated Purchaser completes the relocation of all tangible Assets and the Purchaser’s activities from such premises. Notwithstanding the foregoing, subject to receipt of landlord Consent where required (it being agreed that the Sellers shall only be obligated to use commercially reasonable efforts, without incurring any third-party costs, to obtain any such required Consents) and subject to the Purchaser’s obligation to use commercially reasonable efforts to vacate all such premises as soon as reasonably practicable following the Closing Date, (w) the Purchaser shall be permitted to remain in occupancy at the Sellers’ Ottawa, Ontario facility through but no later than June 30, 2011, (x) the Purchaser shall be permitted to remain in occupancy at the Sellers’ St. Laurent, Quebec facility (BAN1) until the earlier of (1) the day which is sixty (60) days immediately following the Closing Date and (2) December 31, 2010, (y) the Purchaser shall be permitted to remain in occupancy at the Sellers’ St. Laurent, Quebec facility (BAN2) until December 31, 2010, and (z) the Purchaser shall be permitted to remain in occupancy at the Sellers’ Research Triangle Park North Carolina facility through the day which is six (6) months from the Closing Date, in each case provided that the Purchaser compensates the Sellers for the Sellers’ actual, out-of-pocket rent and other occupancy costs with respect to the space so licensed, compensates the Sellers for the services provided to the Purchaser or its Affiliate by a Seller or third party services provider at such facility, such services being those which have been normally and customarily provided to such facility prior to Closing, and indemnifies the Sellers for any liability or damages resulting from the Purchaser’s or a Designated Purchaser’s continued occupancy from the Closing Date through the date upon which the Purchaser or such Designated Purchaser actually surrenders such property in accordance with the requirements of a license agreement in the form of Exhibit 5.16 attached hereto, subject to the following conditions:

(i) The Sellers’ obligation to make any space available to the Purchaser or any other party on the date of or following Closing shall be subject to the Sellers’ right to implement their global real estate strategy, as such strategy develops over time, and in connection therewith to dispose of or retain real estate assets as the Sellers deem appropriate in their sole discretion and the Sellers shall have no liability to the Purchaser or any other party resulting from the implementation of the Sellers’ real estate strategy as contemplated hereby; provided, that, if the Sellers exercise their right to dispose of any real estate asset

prior to the earlier of (A) the date on which the Purchaser vacates the related property at its own election and (B) thirty (30) days after the Closing Date, the Sellers shall give the Purchaser or the relevant Designated Purchaser reasonable prior notice of such disposal and a reasonable opportunity to remove the Assets located thereon; and provided, further, that such notice from the Sellers shall in no event be given later than ten (10) Business Days prior to such disposal.

(ii) To the extent that the Sellers elect to, prior to Closing, terminate a lease or otherwise dispose of real property which is not included among the Assets and which is not a Subleased Real Estate Lease and at which Owned Equipment is located, the Sellers shall provide the Purchaser reasonable prior notice of such termination or disposal (provided, that such notice from the Sellers shall in no event be given later than ten (10) Business Days prior to such termination or disposal) and, following receipt of such notice, the Purchaser shall be permitted reasonable access to the real property for not less than ten (10) Business Days after receipt of the termination notice to identify any Assets acquired hereunder located at the subject premises. The Sellers agree that they will remove and store such Assets at the Sellers’ sole cost until delivery to the Purchaser or a Designated Purchaser at Closing (it being understood that the Sellers shall not be obligated to remove trade fixtures or fixtures, furniture, furnishings or fittings from any such real property or to store the same or to deliver the same at any point to the Purchaser or a Designated Purchaser unless the same are included in the Assets and are specifically identified by the Purchaser for removal). It is further agreed that transfer of any Assets stored in accordance herewith may be made by delivery of a receipt from any warehouse or storage facility entitling the Purchaser or a Designated Purchaser to retrieve all such Assets and the Purchaser shall be responsible for the cost of delivering such Assets to the Purchaser or a Designated Purchaser on or after the Closing Date. In the event the Purchaser fails to identify any Assets that it wishes to have stored, the Sellers shall be entitled to abandon or otherwise dispose of such Assets in their sole discretion without any liability to the Purchaser.

(b) The Sellers shall, within five (5) Business Days after the Closing Date, relocate all the Excluded Assets and the Sellers’ activities from any real property subject to a Sublease to be entered at Closing, with the Purchaser’s cooperation.

(c) In furtherance of the foregoing Sections 5.16(a) and 5.16(b), the Sellers and the Purchaser shall use reasonable efforts to agree on reasonable transition arrangements that provide for reasonable conditions under which each Party shall vacate those premises intended to be used exclusively by the other Party after the Closing Date.

SECTION 5.17 Termination of Overhead and Shared Services. The Purchaser acknowledges and agrees that, except as otherwise expressly provided in the Transition Services Agreement, effective as of the Closing Date (i) all Overhead and Shared Services provided to the Business shall cease and (ii) the Sellers or their Affiliates shall have no further obligation to provide any Overhead and Shared Services to the Business; provided,

however, that the Purchaser and the Sellers acknowledge that overhead costs of the Sellers associated with the provision of services under any Subleases will be included in the rental rates assessed under such Subleases.

SECTION 5.18 Insurance Matters.

(a) The Purchaser acknowledges and agrees that coverage of the assets, tangible or intangible property, Liabilities, ownership, activities, businesses, operations, current and former shareholders, and current and former directors, officers, employees and agents of, the Business (collectively, the “Covered Assets and Persons”) under all current or previous insurance policies of the Sellers and their Affiliates, including all environmental, directors’ and officers’ Liability, fiduciary Liability, employed lawyers, property and casualty flood, ocean marine, and contaminated products insurance policies and all other insurance policies or programs arranged or otherwise provided or made available by the Sellers or their Affiliates that cover (or covered) any of the Covered Assets and Persons at any time prior to the Closing (the “Seller Insurance Policies”) shall cease as of the Closing Date and the Covered Assets and Persons will be deleted in all respects as insured (or additional insured, as the case may be) under all Seller Insurance Policies. Subject to Section 5.18(c), the Sellers shall retain any rights to, including any right to any proceeds received in respect of, any claim pending as of the date hereof or made after the date hereof under any Seller Insurance Policy, even if such claims relates to the capital assets or properties of the Business.

(b) If after the Closing Date the Purchaser or the Sellers (or any of their respective Affiliates) reasonably require any information regarding claim data or other information pertaining to a claim or an occurrence reasonably likely to give rise to a claim (including any pre-Closing claims under the Seller Insurance Policies that are to be covered under the retrospective component of the new insurance policy) in order to give notice to or make filings with insurance carriers or claims adjustors or administrators or to adjust, administer or otherwise manage a claim, then the Sellers or the Purchaser, as the case may be, shall cause such information to be supplied to the other (or their designee), to the extent such information is in their possession and control or can be reasonably obtained by the Sellers or the Purchaser (or their respective Affiliates), as applicable, promptly upon a written request therefor. If the Purchaser desires access to, and utilization of, claims data or information maintained by an insurance company or other Third Party in respect of any claim (including any pre-Closing claims under any Seller Insurance Policies that are covered under the retrospective component of the new insurance policies), the Sellers, at the request of the Purchaser, shall use its commercially reasonably efforts to cause such insurance company or Third Party, at the Purchaser’s sole cost and expense, to transfer such claims data or information to any insurance company or Third Party designated by Purchaser, in each case to the extent permitted by applicable Law. If any Third Party requires the consent of the Sellers or any of their Affiliates to the disclosure of such information, such consent shall not be unreasonably withheld.

(c) Prior to Closing, the Sellers shall at all times maintain their current insurance in respect of the Assets, or in the event any such policies are cancelled or otherwise terminated, shall obtain other substantially comparable insurance policies that have substantially the same terms and conditions and make and pursue any applicable insurance claims related to

damage or destruction to any Assets to the extent that it is in the ordinary course to do so. Notwithstanding anything in this Agreement to the contrary if and to the extent that any item of Asset, wherever located, is destroyed or damaged prior to Closing, and is not replaced or repaired or restored to its condition prior to such damage or destruction, then at Closing, the Sellers shall pay to the Purchaser the amount of any net insurance proceeds received in respect of such Asset (excluding any insurance proceeds related to business interruption insurance) that have not been applied to repair, replacement or restoration, as applicable, and assign to Purchaser or Designated Purchaser any such claim and the rights to receive the proceeds of any such claim that has not yet been finally adjusted. For the avoidance of doubt, in the event that the Sellers transfer such proceeds to the Purchaser, the Sellers shall have no further obligations with respect to the Asset that was destroyed or damaged and the Purchaser shall not be entitled to rescind or terminate this Agreement and such events shall not result in any reduction of the Purchase Price.

SECTION 5.19 Sellers Deposits, Guarantees and Other Credit Support of the Business.

(a) Following the Closing, the Purchaser shall, or shall cause the applicable Designated Purchaser to, unless previously returned and/or released, procure the return or release by the applicable counterparty, as soon as reasonably practicable but in no event later than thirty (30) days after the Closing Date, of any continuing obligation of any Seller or any Affiliate thereof with respect to any Assigned Contract or any Contract, asset or obligation of the Acquired Business (including any guarantee, counter guarantee or credit support provided or procured by, or any letter of credit, performance bond or surety posted or procured by, any Seller or any of its Affiliates or any Third Party on behalf of the Sellers (and with a counter guarantee of the Sellers) in favor of Third Parties), all of which that involve the posting of cash or other collateral, any letter of credit, or any performance bond are set forth on Section 5.19(a) of the Sellers Disclosure Schedule; and

(b) indemnify and hold harmless the Sellers and their Affiliates from and against any Loss resulting from, or relating to, any failure of the Purchaser or Designated Purchasers to comply with the obligations set forth in clause (a) of this Section 5.19.

SECTION 5.20 Receivables. The Purchaser shall, and shall cause the Designated Purchasers to, use commercially reasonable efforts to cooperate with, and provide all necessary assistance to, any Seller to the extent necessary to enable or allow such Seller to collect any Seller Receivables (including, to the extent considered necessary by the Sellers in their reasonable good-faith judgment, collecting or facilitating the collection of any outstanding Seller Receivables on behalf of such Seller). The Purchaser shall not, and shall procure that no Designated Purchaser shall, without the prior written consent of the relevant Seller (such consent not to be unreasonably withheld), (i) compromise, enter into any settlement with, or release any, Third Party in respect of any Seller Receivables or (ii) institute, take any part in, defend, compromise, abandon or call for judgment, any legal proceedings or arbitration in connection with any Seller Receivables.

SECTION 5.21 Use of the Sellers’ Trademarks. Except as

expressly provided in the Trademark License Agreement, as of the Closing Date, neither the Purchaser nor any Designated Purchaser shall have the right to use the name “Nortel” or any other Trademarks owned by the Sellers or any of their Affiliates or any other Trademark employing the word “Nortel” or any confusingly similar Trademarks to any of the foregoing (collectively, the “Sellers’ Trademarks”). Without prejudice to the obligation of the Purchaser to cease and desist from the use of the Sellers’ Trademarks, the Purchaser shall not use the Sellers’ Trademarks in any manner that might dilute, tarnish, disparage or reflect adversely on any Seller or any of the Sellers’ Trademarks or result in any Liability to any Seller.

Such records may be sought under this Section 5.22(a) for any reasonable purpose, including to the extent reasonably required in connection with accounting, litigation, federal securities Law disclosure or other similar needs of the Sellers (other than claims between the Sellers and the Purchaser or any of their respective Subsidiaries under this Agreement or any Ancillary Agreement). Notwithstanding the foregoing, (i) any and all such records may be destroyed by the Purchaser if the Purchaser sends to the Sellers written notice of its intent to destroy such records, specifying in reasonable detail the contents of the records to be destroyed; such records may then be destroyed after the sixtieth (60th) day following such notice unless the Sellers notify the destroying party that the Sellers desire to obtain possession of such records, in which event the Purchaser shall transfer or cause to be transferred the records to the Sellers and the Sellers shall pay all reasonable expenses of the Purchaser in connection therewith and (ii) the Purchaser shall not be required to provide the Sellers access to, or copies of, any Tax records, the sharing of which shall be governed exclusively by Section 6.5 hereof, or audited financial statements covering any pre-Closing period.

(b) Subject to the provisions of Section 6.5 with respect to Tax records, after the Closing, the Sellers shall preserve, until the fifth (5th) anniversary of the Closing Date (or such longer period as may be required under applicable Law), all pre-Closing Date records to the extent relating to the Acquired Business possessed by, or that comes into the possession of, such Person. After the Closing Date and up until the fifth (5th) anniversary of the Closing Date (or such longer period as may be required under applicable Law), upon any reasonable request from the Purchaser, any Designated Purchaser or their respective representatives, the relevant Seller shall, and/or shall cause the Person holding such records to, (i) provide to the Purchaser, any Designated Purchaser or their respective representatives reasonable access to such records (to the extent permitted by applicable Law or Contract), and to that portion of records or information relating to the Business that would constitute Business Information but for the fact that it does not relate exclusively to the Business, during normal business hours and (ii) permit the Purchaser, any Designated Purchaser or their respective representatives to make copies of such records or information referred to in clause (i), in each case at no cost to the Purchaser, such Designated Purchaser or their respective representatives (other than for reasonable costs of segregating information commingled with information not relating to the Business and out-of-pocket expenses) and in such a manner not to interfere with the normal operations of the business of the Sellers; provided, however, that nothing herein shall require any Seller or any of its Affiliates to disclose any information to the Purchaser, any Designated Purchaser or their respective representatives if such disclosure would jeopardize any attorney-client or other legal privilege or contravene any applicable Law, fiduciary duty or agreement (it being understood that the Sellers shall cooperate in any reasonable efforts and requests for waivers that would enable otherwise required disclosure to the Purchaser, any Designated Purchaser or their respective representatives to occur without so jeopardizing privilege or contravening such Law, duty or agreement) or, other than as provided in Section 6.5, require the Sellers to disclose their Tax records. Such records may be sought under this Section 5.22(b) for any reasonable purpose, including to the extent reasonably required in connection with accounting, litigation, federal securities Law disclosure or other similar needs of the Purchaser, any Designated Purchaser or their respective representatives (other than claims between the Sellers and the Purchaser or any of their respective Subsidiaries under this Agreement or any Ancillary Agreement). Notwithstanding the foregoing, (y) any and all such records may be destroyed by the Sellers if the Sellers send to the Purchaser written notice of their intent to destroy such records, specifying in reasonable detail the contents of the records to be destroyed; such records may then be destroyed after the sixtieth (60th) day following such notice unless the Purchaser notifies the destroying party that the Purchaser or any Designated Purchaser desire to obtain possession of such records, in which event the Sellers shall transfer or cause to be transferred the records to the Purchaser and the Purchaser shall pay all reasonable expenses of the Sellers in connection therewith and (z) the Sellers shall not be required to provide the Purchaser, any Designated Purchaser or their respective representatives access to, or copies of, any Tax records, the sharing of which shall be governed exclusively by Section 6.5 hereof, or audited financial statements covering any pre-Closing period.

(b) The Sellers and the Purchaser will cooperate to determine how to segregate and demise the subleased premises, including the size and configuration of space to be subleased to the Purchaser or a Designated Purchaser (which shall be based upon the employee headcount reasonably agreed between the Purchaser and the Sellers on or prior to the Closing Date, as adjusted to take into account any laboratory and other non-desk space to be subject to a Sublease, which shall also take into account the continued marketability and required contiguity of that portion of the premises to be subject to the related Sublease and the premises not to be subject to the related Sublease and which shall not, in any instance, take into account any plans of the Purchaser to relocate employees included in the aforementioned employee headcount to other locations) and provide relevant information (subject to confidentiality limitations) on the subleased premises to the other; provided, that it is understood and agreed that all costs of such segregation and demising will be the sole responsibility of the Purchaser and that the Purchaser’s plans and specifications therefor will be subject to the Sellers’ reasonable approval. Prior to Closing, the Sellers will not engage in any segregation and demising activities to be undertaken (x) in order to maintain the marketability of the applicable premises prior to Closing or (y) in order to move any Owned Equipment from the applicable premises.

(c) The relevant Sellers shall provide, or cause a third party services provider (each, including any of its subcontractors, a “Service Provider”) to provide, with respect to any space subject to a sublease, to the Purchaser or its Affiliate services which are substantially the same in scope as the services which have been normally and customarily provided to the applicable space prior to Closing.

ARTICLE VI.

TAX MATTERS

SECTION 6.1 Transfer Taxes.

(a) The Parties agree that the Purchase Price is exclusive of any Transfer Taxes. The Purchaser shall (on behalf of itself and the Designated Purchasers) promptly pay directly to the appropriate Tax Authority all applicable Transfer Taxes imposed upon or payable

100

or collectible or incurred in connection with this Agreement or the transactions contemplated herein, or that may be imposed upon or payable or collectible or incurred in connection with the execution of any other Transaction Document; provided, that if any such Transfer Taxes are required to be collected, remitted or paid by a Seller or any Subsidiary, Affiliate, representative or agent thereof, such Transfer Taxes shall be paid by the Purchaser to such Seller, Subsidiary, Affiliate, representative or agent, as applicable, at the Closing or thereafter, as requested of or by the applicable Seller. Upon request from the Sellers, the Purchaser shall provide to the Sellers an original receipt (or such other evidence as shall be reasonably satisfactory to the Sellers) evidencing the payment of Transfer Taxes by the Purchaser to the applicable Tax Authority under this Section 6.1. For the avoidance of doubt the Purchaser shall remain liable in respect of any Transfer Taxes as provided in this Section 6.1 regardless of the date that the Assets are removed from the premises of a Seller or any Seller’s supplier. The Sellers, the Purchaser and any Designated Purchasers shall cooperate in timely filing all Tax Returns as may be required in connection with the payment of Transfer Taxes that are the subject of this Section 6.1. The Sellers, on the one hand, and the Purchaser and the Designated Purchasers, on the other hand, shall, as appropriate, use commercially reasonable efforts to execute and deliver all instruments and certificates reasonably necessary to enable the other to comply with any filing requirements and Laws relating to any such Transfer Taxes.

(b) The Parties shall make commercially reasonable efforts to cooperate in good faith to mitigate the Purchaser’s liability for any Transfer Taxes for which the Purchaser is liable under Section 6.1(a), provided that any such cooperation to be provided in this Section 6.1(b) shall not include or extend to (a) a liquidation or restructuring of a Seller or any business of a Seller, including the transfer of any assets or Assets or liabilities or Assumed Liabilities between Sellers or their Affiliates, except in the Sellers’ discretion, but in no case if there is a material cost to Seller or its Affiliates resulting from such liquidation or restructuring unless the Seller or the relevant Affiliate is indemnified (prior to such liquidation or restructuring) against any cost or expense of such liquidation or restructuring to its satisfaction (acting at all times reasonably and in good faith); (b) any action or omission that would result in the imposition on any Seller or any Affiliate of any Seller of any additional Tax liability or making any additional payment to any Tax Authority or Government Entity in respect of Tax which is an Excluded Liability, unless such Seller or Affiliate is (prior to the relevant action or omission) indemnified against such additional Tax liability or payment; (c) any action or omission that would result in any material out of pocket cost or expense for any Seller or any Affiliate of any Seller, unless such Seller or Affiliate is (prior to the relevant action or omission), indemnified against such cost or expense to their satisfaction (acting at all times reasonably and in good faith) by the Purchaser; (d) any action or omission which would cause the Sellers or any Affiliates of the Sellers to be in contravention of any applicable Law (including Bankruptcy Law) or published practice of a Tax Authority; (e) changing the identity or Tax residence of any Sellers, the location of any Assets or Assumed Liabilities, the nature or extent of any Assets or Assumed Liabilities, the Assets or Assumed Liabilities to be transferred by any particular Seller or the structure of the transaction as an asset sale rather than the sale of any form of entity, except in the Sellers’ commercially reasonable discretion, but in no case if there is a material cost to Seller or its Affiliates resulting from such action, unless the Seller or the relevant Affiliate is indemnified (prior to such action) against any cost or expense of such action to its satisfaction (acting at all times reasonably and in good faith); or (f) any reduction in the obligations of the Purchaser or rights of the Sellers, in each case under Section 2.4.

101

(c) If the Purchaser or any Designated Purchaser wishes to claim any exemption relating to, or a reduced rate of, or make an election with the effect of reducing, Transfer Taxes, in connection with this Agreement or the transactions contemplated herein, or in connection with the execution of any other Transaction Document, the Purchaser or any Designated Purchaser, as the case may be, shall be solely responsible for ensuring that such exemption, reduction or election applies and, in that regard, shall provide the Sellers prior to Closing with its permit number, GST/HST, VAT, provincial sales taxes or other similar registration numbers and/or any appropriate certificate of exemption, election and/or other document or evidence to support the claimed entitlement to such exemption or reduction by the Purchaser or such Designated Purchaser, as the case may be. All Parties shall make commercially reasonable efforts to cooperate to the extent necessary to obtain any such exemption or reduction.

(d) Provided that, in the opinion of the Sellers the sale qualifies for such an election or application, the Purchaser (or relevant Designated Purchaser) will jointly execute with the applicable Seller an election under Section 167(1) of Part IX of the Excise Tax Act (Canada) and any similar election or application provided under applicable provincial Laws, in the forms prescribed for such purposes, such that the sale and purchase of the Assets will take place without payment of any GST/HST. The Purchaser (or the relevant Designated Purchaser) will file such election with the relevant Tax Authority in the manner and within the time prescribed by Law and will provide the applicable Seller with a copy of the election and with satisfactory evidence that the election has been filed in a timely manner. The applicable Seller(s) confirms that it is registered for purposes of the Excise Tax Act (Canada) and its GST/HST registration number is 119409258RT0001 (in the case of NNL) and 118802974RT0001 (in the case of Nortel Networks Technology Corporation (“NNTC”). The Purchaser (or the relevant Designated Purchaser(s), as applicable) shall be responsible and indemnify and hold harmless the applicable Seller(s) for any GST/HST (and any comparable provincial Taxes) to the extent payable notwithstanding the elections contemplated by this Section 6.1, plus any interest and/or penalties payable as a consequence thereof.

SECTION 6.2 Withholding Taxes.

(a) To the extent that the Purchaser or a Designated Purchaser is required under the Code or any provision of U.S. state or local or non-U.S. Law to deduct and withhold an amount from the Purchase Price, such withheld amounts shall be treated for all purposes of this Agreement and any other Transaction Document, as having been paid to the Persons in respect of which such deductions and withholdings were made. The Purchaser and the Designated Purchasers shall promptly remit such withheld amounts to the appropriate Government Entity. None of the Parties is aware of any obligation to deduct and withhold any material amounts from the Purchase Price under the Code or any provision of U.S. state or local, or non-U.S. Law, with respect to the making of such payment. If any of the Parties learns of any such obligation on or prior to the Closing Date, then (i) in the case of a Seller, such Seller shall promptly provide reasonable notice of such obligation to the Purchaser and (ii) in the case of the Purchaser, the Purchaser shall promptly provide reasonable notice of such obligation to the Sellers. The Parties shall make commercially reasonable efforts to cooperate in good faith to minimize the amounts

102

that the Purchaser or Designated Purchasers, as the case may be, are required to deduct and withhold.

(b) Notwithstanding the foregoing, if the Purchaser or a Designated Purchaser is required for any reason to deduct or withhold from any payment made pursuant to this Agreement or any other Transaction Document, which payment is for, or deemed to be for, the purchase or use of Intellectual Property (including the license thereof), for any Tax imposed by a Tax Authority, and if the applicable Seller is unable to recover such Tax from such Tax Authority, the payment of the Purchase Price shall be increased to an amount which, after taking into account such deduction or withholding, will result in payment to the applicable Seller of the full amount such Seller would have received from the Purchaser or such Designated Purchaser had no such deduction or withholding been made. The Purchaser shall or shall cause such Designated Purchaser to promptly furnish the Sellers with such evidence as may be required by the applicable Tax Authorities to establish that any such Tax has been paid, and shall indemnify and hold harmless the Sellers on an after-Tax basis from any liability for penalties or interest due to the payor’s failure to timely withhold and remit amounts in respect of Taxes to the applicable Tax Authority.

(c) The Parties shall cooperate reasonably in good faith to reduce or eliminate, or maximize the potential for the refund or recovery of, any applicable Taxes to the extent allowed under applicable Law, including through the provision by either Party to the other Party any certification, form, legally valid invoice or other documentation reasonably requested by such other Party to allow for such reduction, elimination, refund or recovery of such Taxes. If the Purchase Price is increased pursuant to Section 6.2(b) or an additional amount is paid by the Purchaser or a Designated Purchaser pursuant to Section 2.4(a) and any of the Sellers subsequently obtains and is entitled to retain an actual cash refund of Tax or an actual reduction in a Tax liability (including by virtue of obtaining a deduction for Tax purposes) in respect of such increase in Purchase Price or such additional payment, then such Seller shall reimburse the Purchaser or a Designated Purchaser for an amount equal to the lower of the amount of: (i) such refund or such actual reduction, after deducting any Tax thereon and the reasonable costs and expenses incurred in obtaining such refund or reduction, and (ii) the amount of increase in Purchase Price or additional payment in respect of which such refund or actual reduction arises.

SECTION 6.3 Tax Characterization of Payments Under This Agreement. The Sellers and the Purchaser agree to treat all payments made either to or for the benefit of the other Party under this Agreement (other than payment of the Estimated Purchase Price and any interest payments) as adjustments to the Purchase Price for Tax purposes and that such treatment shall govern for purposes hereof to the extent permitted under applicable Tax Law.

SECTION 6.4 Apportionment of Taxes.

(a) Except as otherwise provided in this Article VI, (i) the Sellers shall and shall cause the Other Sellers, as the case may be, to bear (A) all Taxes of any kind relating to the Assets or the conduct or operation of the Acquired Business for all Tax periods or portions

103

thereof ending on or before the Closing Date and (B) all Taxes of any Seller imposed on or measured by such Seller’s net income, gross income, capital, gross receipts, profits, and all Taxes of the same or of a similar nature, for any Tax period (excluding Transfer Taxes that are the responsibility of the Purchaser pursuant to Section 6.1(a)) and (ii) the Purchaser shall and shall cause the Designated Purchasers to bear all Taxes relating to the Assets or the conduct or operation of the Acquired Business for all Tax periods or portions thereof beginning after the Closing Date.

(b) For purposes of this Agreement, any Taxes for a “Straddle Period” (a Tax period that includes, but does not end on, the Closing Date) shall be apportioned between the Sellers, on the one hand, and the Purchaser and the Designated Purchasers, on the other hand, based on the portion of the period ending on and including the Closing Date and the portion of the period beginning after the Closing Date, respectively. The amount of Taxes shall be allocated between portions of a Straddle Period in the following manner: (i) in the case of a Property Tax, the amount of Tax allocable to a portion of the Straddle Period shall be the total amount of such Tax for the period in question multiplied by a fraction, the numerator of which is the total number of days in such portion of such Straddle Period and the denominator of which is the total number of days in such Straddle Period, and (ii) in the case of all other Taxes (other than Transfer Taxes allocated under Section 6.1), such Taxes shall be determined from the books and records of the relevant Person as though the taxable period terminated at the close of business on the Closing Date.

SECTION 6.5 Records.

(a) Except as provided elsewhere in this Section 6.5, after the Closing Date, (i) the Purchaser and the Designated Purchasers, on the one hand, and the Sellers, on the other hand, will make available to the other, as reasonably requested, and to any Tax Authority, all records or documents relating to liability for Taxes with respect to the Assets, the Assumed Liabilities, or the Business for all periods prior to the Closing (including any item relating to a Canadian tax deduction or Canadian tax credit in respect of scientific research and experimental development), and will preserve such records or documents until the expiration of any applicable statute of limitations or extensions thereof, and (ii) in the event that one party needs access to records or documents in the possession of a second party relating to any of the Assets, the Assumed Liabilities, or the Business for purposes of preparing Tax Returns or complying with any Tax audit request, subpoena or other investigative demand by any Tax Authority, or for any other legitimate Tax-related purpose (including conducting any proceeding with respect of Taxes) not injurious to the second party, the second party will allow representatives of the other party access to such records or documents during regular business hours at the second party’s place of business for the sole purpose of obtaining information from records or documents for use as aforesaid and will permit such other party to make extracts and copies thereof as may be necessary or convenient, provided, however, that nothing herein shall require the Purchaser and the Designated Purchasers, on the one hand, and the Sellers, on the other hand, to disclose any information to the other if such disclosure would jeopardize any attorney-client or other legal privilege or contravene any applicable Law, fiduciary duty or agreement. The obligation to cooperate pursuant to this Section 6.5 shall terminate at the time the relevant applicable statute of limitations expires (giving effect to any extension thereof).

104

(b) Notwithstanding Section 6.5(a), the Sellers shall use their reasonable best efforts to calculate and provide to the Purchaser historical data relating to the qualified research expenses and gross receipts of the Business pursuant to Section 41 of the Code (including in particular Section 41(f)(3)(A) of the Code) and any analogous data under corresponding provisions of state, local or foreign law as requested by the Purchasers or the Designated Purchasers, provided that such historical data is available to the Sellers or could be made available to the Sellers with Sellers’ reasonable best efforts. Sellers shall use their reasonable best efforts to update such historical data to reflect any relevant adjustments arising after the Closing and provide copies of any such updates to the Purchaser or the applicable Designated Purchaser within ten (10) days of the date on which such adjustment is made. Notwithstanding the foregoing, nothing herein shall require Sellers to indemnify the Purchaser to the extent a credit of the Purchaser under section 41 of the Code (or any corresponding provisions of state, local or foreign law) is unavailable or challenged by the relevant Taxing Authority.

(c) At any time within the ten (10) years immediately following the Closing, NNL and NNTC may cause copies of Restricted Technical Records to be placed into escrow with the Records Custodian, who shall hold such Restricted Technical Records for a term ending no later than ten (10) years after the Closing Date in accordance with an escrow agreement between the Purchaser (or the relevant Designated Purchaser, as applicable), NNL and NNTC and the Records Custodian, in form satisfactory to the Purchaser (or the relevant Designated Purchaser), NNL and NNTC. The escrow agreement will provide for access to the copies of the Restricted Technical Records only by the relevant Canadian Tax Authority or by Tax advisors of any purchaser (“Tax Credit Purchaser”) relating to the scientific research and experimental development Tax credits of NNL and NNTC under the Income Tax Act (Canada), and only if such advisors have executed an appropriate confidentiality agreement in form satisfactory to the Purchaser (or the relevant Designated Purchaser), acting reasonably. The access permitted by the escrow agreement shall be only for the limited purpose of defending any audit, claim or action by any Canadian Tax Authority in respect of the characterization of expenditures by NNL or NNTC as qualified expenditures on scientific research and experimental development for purposes of the applicable provisions of the Income Tax Act (Canada) (“Qualified Expenditures”).

(d) The Purchaser shall use reasonable efforts to make available to the relevant Taxing Authority or Tax advisors of the Tax Credit Purchaser, those former employees of NNL or NNTC, as the case may be, with direct knowledge of the Qualified Expenditures who are then employed by the Purchaser and whose cooperation is necessary for the purpose of defending any audit, claim or action by any Taxing Authority of the characterization of expenditures by NNL or NNTC, as the case may be, as Qualified Expenditures, and provided, that such advisors have executed an appropriate confidentiality agreement satisfactory to the Purchaser.

(e) The Purchaser shall have no obligation to provide any access under this provision unless the Seller (if there is no Tax Credit Purchaser in respect of the request for access) or the Tax Credit Purchaser pays all the Purchaser’s reasonable expenses in connection with the foregoing provisions, including a reasonable per diem rate for access to former employees of NNL or NNTC, as the case may be (based on the total compensation of the employee at the time access is provided).

105

(f) At the request of the Purchaser, the Sellers shall provide reasonable access to records and employees of the Sellers to assist the Purchaser in claiming any future scientific research and experimental development Tax credits for Qualified Expenditures. The Sellers shall have no obligation to provide any access under this provision unless the Purchaser pays all of the Sellers’ reasonable expenses in connection with the foregoing provisions, including a reasonable per diem rate for access to employees of the Sellers (based on the total compensation of the employee at the time access is provided).

SECTION 6.6 Tax Disclosure. Notwithstanding anything to the contrary in this Agreement, except as reasonably necessary to comply with applicable securities laws and regulations, any Party may (i) consult any Tax adviser regarding the U.S. federal income Tax treatment or Tax structure of the transactions contemplated by this Agreement, and (ii) disclose to any and all Persons, without limitation of any kind, the U.S. federal income Tax treatment and Tax structure of the transactions contemplated hereunder and all materials of any kind (including opinions or other Tax analyses) that are provided to such Person relating to such Tax treatment and Tax structure (but without disclosure of identifying information or any non-public commercial or financial information); provided, however, that clause (ii) of this paragraph shall not apply until the date of the public announcement of the execution of this Agreement and performance of the transactions contemplated hereunder. For this purpose, “Tax structure” is limited to any facts relevant to the U.S. federal income Tax treatment of the transactions contemplated hereunder.

SECTION 6.7 Tax Returns.

(a) The Sellers shall be responsible for the preparation and timely filing (taking into account any extensions received from the relevant Tax Authorities) of all Tax Returns in respect of the Assets or the Acquired Business, for all Pre-Closing Taxable Periods (other than any Tax Returns with respect to Transfer Taxes (“Transfer Tax Returns”) described below in Section 6.7(b) or Tax Returns for any Straddle Period). Such Tax Returns shall be true, correct and complete in all material respects. Except as otherwise provided in this Agreement, all Taxes indicated as due and payable on such Tax Returns shall be paid by (or shall be caused to be paid by) the Sellers as and when required by Law.

(b) Each Transfer Tax Return with respect to Transfer Taxes imposed in respect of this Agreement and the transactions contemplated hereunder or in respect of the execution of any other Transaction Document shall be prepared by the Party that has primary responsibility for filing such Transfer Tax Return pursuant to the applicable Tax Laws. The Sellers shall make available to the Purchaser that portion of such Transfer Tax Returns prepared by the Sellers that is applicable to the sale and purchase transaction contemplated by this Agreement, and, to the extent not already disclosed, such information as will enable the Purchaser to review such portion of such Transfer Tax Returns, at least five (5) Business Days before such Tax Returns are due to be filed. The Purchaser shall be entitled to comment on any Transfer Tax Return prepared by a Seller prior to making any payment in respect thereof, such comments to be provided at least three (3) Business Days before such Transfer Tax Returns are due to be filed, and in the event of disagreement between the Parties, and the relevant Transfer Tax Return shall be filed in accordance with the Purchaser’s reasonable comments, it being

106

understood that the Purchaser shall remain responsible for any Transfer Taxes for which it is responsible pursuant to Section 6.1(a) whether or not shown on such Tax Return. The Purchaser shall pay to the Sellers any amount of Transfer Taxes payable in respect of Transfer Tax Returns to be filed by the Sellers pursuant to this Section 6.7(b) at least one (1) Business Day before such Transfer Tax becomes due and payable in each case to the extent such Transfer Taxes are the responsibility of the Purchaser pursuant to Section 6.1(a).

(c) The Purchaser or a Designated Purchaser shall be responsible for the preparation and timely filing (taking into account any extensions received from the relevant Tax Authorities) of all Tax Returns with respect to the Assets or the Acquired Business for all Straddle Periods. Such Tax Returns shall be true, correct and complete in all material respects. All Taxes indicated as due and payable on such Tax Returns shall be paid by (or shall be caused to be paid by) the Purchaser or a Designated Purchaser as and when required by Law; provided, however, that Taxes that are the responsibility of the Sellers pursuant to this Article VI shall be paid by the Sellers to the Purchaser or Designated Purchaser no later than one (1) Business Day prior to the due date for the applicable Straddle Period Tax Return.

(d) The Sellers shall be entitled to review and comment on any Tax Return (other than a Transfer Tax Return described in Section 6.7(b)) prepared by the Purchaser or a Designated Purchaser for any Straddle Period before any such Tax Return is filed. The Purchaser shall submit a draft of any such Tax Return to the Main Sellers at least thirty (30) days before the date such Tax Return is required to be filed with the relevant Tax Authority. The Main Sellers shall have ten (10) days after the date of receipt thereof to submit to the Purchaser, in writing, the Main Sellers’ written comments with respect to such Tax Return. The Purchaser shall notify the Main Sellers within five (5) days after receipt of such comments of (a) the extent, if any, to which the Purchaser accepts such comments and will file such Tax Return in accordance therewith and (b) the extent, if any, to which the Purchaser rejects such comments. To the extent the Purchaser rejects the comments of the Main Sellers, the Purchaser and the Main Sellers promptly shall negotiate in good faith to resolve their disagreements; if no agreement has been reached within three (3) days, the parties immediately shall appoint an Accounting Arbitrator to determine the correct manner for reporting the items that are in dispute and shall provide to the Accounting Arbitrator all relevant information. The Accounting Arbitrator shall have ten (10) days to submit its determination, which shall be binding upon the Parties, and the Purchaser shall file such Tax Return in accordance therewith. Notwithstanding the preceding sentence, if the Accounting Arbitrator shall not have submitted its determination on or before the date such Tax Return is required to be filed with the relevant Tax Authority (giving effect to any valid extensions), the Purchaser shall file its original draft of such Tax Return and shall, upon receiving the Accounting Arbitrator’s later determination and to the extent permitted under applicable Law, promptly file an amended return in accordance therewith. The Sellers shall pay to the Purchaser such amount as they in good faith believe that they owe. To the extent the Accounting Arbitrator determines that the amount of Sellers’ liability is greater than the amount actually paid to the Purchaser prior to such due date, the Sellers shall pay to the Purchaser such excess within three (3) Business Days after receiving the Accounting Arbitrator’s determination. To the extent the Accounting Arbitrator determines that the amount of Sellers’ liability is less than the amount actually paid to the Purchaser prior to such due date, the Purchaser shall refund the amount overpaid to the Sellers within three (3) Business Days after receiving the Accounting

107

Arbitrator’s determination. The fees and expenses of the Accounting Arbitrator shall be paid by the Party whose position is deemed to be least correct by the Accounting Arbitrator.

(e) To the extent any Tax Returns of the Sellers that are listed in Section 4.13(a) of the Sellers Disclosure Schedule are required to be filed by the Sellers have not been filed by the Closing Date, such Tax Returns shall be filed as soon as reasonably practicable but in no event later than three (3) months after the Closing Date; provided, however, that this Section 6.7(e) shall not be applicable to the extent that no Asset can be made subject to a Tax Lien and neither the Purchaser nor any Designated Purchaser could be held liable for Taxes of that Seller.

SECTION 6.8 Canadian Tax Election.

(a) Provided that a portion of the Assets transferred pursuant to this Agreement by the Sellers to the Purchaser or each Designated Purchaser which is a resident of Canada for purposes of the Income Tax Act (Canada) (and any equivalent provincial statute) is being transferred to the Purchaser (or the relevant Designated Purchaser) in consideration for the Purchaser (or the relevant Designated Purchaser) assuming prepaid obligations of the Seller to deliver goods or provide services in the future, the Sellers and the Purchaser (or the relevant Designated Purchaser) will prepare, execute and file, on a timely basis and using any prescribed form, a joint election under subsection 20(24) of the Income Tax Act (Canada) (and any equivalent provincial statute) as to such assumption hereunder, and prepare their respective Tax Returns in a manner consistent with such joint election. The elected amount will be jointly determined by the Sellers and the Purchaser (or relevant Designated Purchaser), acting reasonably. The Sellers and the Purchaser (or relevant Designated Purchaser) will make any required elections under corresponding provincial or territorial law and the foregoing provisions will apply mutatis mutandis in respect thereof.

(b) To the extent the Seller and the Purchaser (or the relevant Designated Purchaser) cannot agree on the amount to be elected under subsection 20(24) of the Income Tax Act (Canada) (and any equivalent provincial statute), the Seller and the Purchaser (or the relevant Designated Purchaser) promptly shall negotiate in good faith to resolve their disagreements; if no agreement has been reached within five (5) days, the relevant parties immediately shall appoint an Accounting Arbitrator to determine the correct amount to be elected and shall provide to the Accounting Arbitrator all relevant information. The Accounting Arbitrator shall have thirty (30) days to submit its determination, which shall be binding upon the Parties, and the Parties shall file all relevant elections and Tax Returns in accordance therewith. The fees and expenses of the Accounting Arbitrator shall be paid by the Party whose position is deemed to be least correct by the Accounting Arbitrator.

SECTION 6.9 Other Tax Matters.

(a) In the event that any Tax Authority shall (A) make any claim against any Purchaser Parties for any Taxes that are Excluded Liabilities of any Seller or (B) have in its favor a Lien on any of the Assets arising out of the non-payment of any Taxes that are Excluded

108

Liabilities of a Seller (any Taxes described in (A) and (B) above hereby are referred to collectively as “Excluded Taxes”), such Purchaser Party shall be entitled to recover all Losses arising out of or in connection with such Excluded Taxes promptly (in accordance with the following provisions) by obtaining cash from the Succession Tax Escrow Amount in an amount equal to the aggregate amount of such Losses, provided that (i) the aggregate amount to be recovered under this Section 6.9 in respect of such Losses shall not exceed the Succession Tax Escrow Amount (plus any accrued interest on the Succession Tax Escrow Amount); and (ii) the only Losses recoverable under this Section 6.9 shall be the amount of Excluded Taxes claimed, and any additional Losses incurred by a Purchaser Party after the earlier of the date on which a Tax Authority has made a claim described in (A) above or registered or imposed a Lien described in (B) above, as applicable.

(b) If a claim for Losses under Section 6.9(a) (a “Tax Claim”) is to be made by a Purchaser Party, the Purchaser shall give written notice (a “Tax Claim Notice”) on behalf of such Purchaser Party to the Main Sellers promptly after such Purchaser Party becomes aware that a Tax Authority has made a claim against it for any Excluded Taxes or that such Taxes have given rise to a Lien described in clause (B) of subsection (a) above, as applicable, stating, with reasonable specificity, the basis for the Tax Claim, and including a copy of all relevant documents received from the relevant Tax Authority. In the event that any Purchaser Party is entitled to recover the amount of any such Losses from the Succession Tax Escrow Amount, the Purchaser and the Main Sellers shall issue joint written instructions to the Escrow Agent authorizing distribution of the amount of such Losses to such Purchaser Party and such Purchaser Party shall be responsible for paying over to the relevant Tax Authority the amount of Excluded Taxes distributed to it from the Succession Tax Escrow Amount to the extent it has not already done so at the time of the distribution of such amount from such fund and shall provide Sellers with such written evidence as is reasonably requested in writing to confirm that payment to the relevant Tax Authority has been duly made.

(c) On the date that is the first Business Day after the first anniversary of the Closing Date, the Purchaser and the Main Sellers shall deliver to the Escrow Agent joint written instructions to release to the Distribution Agent, on behalf of the Sellers and the EMEA Sellers, any remaining portion of the Succession Tax Escrow Amount (including any accrued interest thereon) in excess of an amount equal to the aggregate of all Tax Claims which have been asserted prior to such date evidenced by one or more Claim Notices and which remain pending and unresolved on such date. Thereafter, as soon as reasonably practicable after the final resolution of the last Tax Claim, the Purchaser and the Main Sellers shall issue joint written instructions to the Escrow Agent to release to the Distribution Agent, on behalf of the Sellers and the EMEA Sellers, any remaining portion of the Succession Tax Escrow Amount (including any accrued interest thereon) after any distributions to Purchaser required hereby.

(d) In the event that a Claim Notice is served, the Purchaser shall take such steps as are commercially reasonable to mitigate or otherwise defend the assessment(s) made by the relevant Tax Authority. In the event that a payment from the Succession Tax Escrow Amount is made to a Purchaser Party pursuant to this Section 6.9, and subsequently a Purchaser Party becomes entitled to and receives a refund that is attributable to Excluded Taxes that were paid to such Purchaser Party from the Succession Tax Escrow Amount (in whole or in part), then the Purchaser shall, or shall cause the relevant Purchaser Party to, promptly pay to the

109

Distribution Agent, on behalf of the Sellers and the EMEA Sellers, an amount equal to the portion of such refund so attributable (including any interest paid in connection with such portion), net of reasonable out-of-pocket expenses (including taxes) incurred by the Purchaser Party in obtaining such portion, unless (i) such refund is received prior to the first anniversary of the Closing Date or (ii) at the time the refund is received, the Succession Tax Escrow Amount is less than the sum of the Tax Claims that are evidenced by one or more Claim Notices and which remain pending and unresolved on such date, then, in each case, the Purchaser Party shall pay the net amount of such portion to the Escrow Agent to be added to the Succession Tax Escrow Amount.

(e) Notwithstanding anything to the contrary in this Agreement, recourse to the Succession Tax Escrow Amount under this Section 6.9 shall be the sole and exclusive remedy available to the Purchaser and any Designated Purchaser following the Closing in respect of any liability for Taxes that are Excluded Liabilities of a Seller or any liability for Taxes that give rise to any Lien on any Assets in each case in the jurisdictions set forth on Section 6.9(e) of the Sellers Disclosure Schedule.

SECTION 6.10 Cooperation. The Sellers and the Purchaser shall make commercially reasonably efforts (taking into account available resources) to cooperate with each other in connection with the conduct of any Tax audit, investigation, dispute, or appeal relating to the Business or the Assets.

ARTICLE VII.

EMPLOYMENT MATTERS

SECTION 7.1 Employment Obligations with Respect to Employees.

7.1.1 Employment Terms. The Purchaser hereby agrees to offer employment to at least ninety-five percent (95%) of the Employees as set forth on Section 7.1 of the Sellers Disclosure Schedule. Promptly following the latest of the granting of the U.S. Sale Order and the Canadian Approval and Vesting Order and receipt of all Regulatory Approvals, the Purchaser shall, or shall cause a Designated Purchaser to, extend a written offer of employment (each, an “Offer” and collectively, “Offers”) in a manner that provides no less than a one-week Employee consideration period (“Offer Consideration Period”), in a form reasonably agreed by the Primary Parties (provided that the Seller provides feedback on any proposed offer letter or any revision thereof within 48 hours following receipt of the initial proposed offer letter draft from the Purchaser) and in compliance with applicable Law to each Employee (other than Employees whose employment transfers automatically by operation of Law to the Purchaser or a Designated Purchaser) with such employment to take effect under the terms stated herein as of the Effective Hire Date, as defined below. Offers shall, except to the extent otherwise required by Law, be for employment with (a) an annual base salary and an annual target incentive opportunity for each such Employee at least equal to the (i) annual base salary and (ii) annual target incentive

110

opportunity (excluding the KEIP, KERP and the Nortel Special Incentive Plan) for such Employee as set out in the Employee Information (provided that the form and performance metrics of such incentive opportunity shall be determined by the Purchaser in its sole discretion), and further provided that such target incentive opportunity shall be until the earlier of 12 months following the Closing Date and December 31, 2011, (b) employment in a reasonably comparable position as set out for the Employee in the Employee Information, (c) a location reasonably contiguous to their current location for the nine month period following the Closing Date as set out in the Employee Information, and (d) a deemed consent by the Employee to allow the Seller to transfer such Employee’s Employee Records as of the Effective Hire Date. Employees whose employment transfers by operation of Law shall be employed on terms and conditions of employment that are no less favorable than those set out above. For purposes of this Agreement, to the extent certain terms and conditions of employment are required to be maintained under applicable Law in order to avoid the Sellers incurring severance or other termination obligations with respect to Employees at any time after the Closing Date, such terms and conditions shall be deemed required by applicable Law. The Sellers shall provide to the Purchaser available and relevant information, and the Sellers and the Purchaser shall cooperate in good faith, so as to enable the Purchaser to comply with its undertakings under this Section 7.1.1. Employees’ employment with the Purchaser or a Designated Purchaser or, with respect to Employees whose employment transfers by operation of Law, continued employment after the Effective Hire Date, shall not include a probationary period and for Employees located outside of the United States shall not be conditioned upon such employees satisfactorily completing a drug test, or other employment screening processes unless such screening process is required by applicable Law; provided, however, that Employees’ employment with the Purchaser or Designated Purchaser may be contingent on (i) if, and only to the extent, required pursuant to the terms and conditions of any Customer Contract or similar contract or arrangement to which the Purchaser or a Designated Purchaser is a party, with respect to Employees providing services pursuant to the terms and conditions of such Customer Contract or similar contract or arrangement only, satisfactory completion of a background check, to the extent permitted and consistent with applicable Law, (ii) Employees’ providing evidence that they are legally permitted to be employed by the Purchaser or a Designated Purchaser, as required by applicable Law, (iii) in the case of an Inactive Employee (other than an Employee whose employment transfers by operation of Law), such Employee’s return to active status with the Sellers and (iv) the Closing. The Purchaser shall notify the Main Sellers of the acceptance and rejections of Offers that have been received from each of the Employees (A) periodically during the Offer Consideration Period and (B) in total within three (3) Business Days following the end of the Offer Consideration Period. Any Employee who accepts an Offer and commences employment with the Purchaser or a Designated Purchaser, as applicable, pursuant to this Agreement and any Employees whose employment transfers by operation of Law shall all be deemed to be a Transferred Employee for all purposes of this Agreement. Inactive Employees shall remain employed by the relevant Seller until the first (1^st) Business Day immediately following the date the Inactive Employee is released to return to active employment in accordance with the Sellers’ leave policies and on which such Inactive Employee reports to work with the Purchaser or a Designated Purchaser. To the extent not already provided pursuant to Section 5.6(e), the Sellers will use commercially reasonable best efforts to provide to the Purchaser Employee Records on or prior to seven (7) Business Days following the Effective Hire Date. The Purchaser or a Designated Purchaser shall use reasonable best efforts from the date hereof until the Closing Date to obtain, at its cost, such

111

visas or permits as are required for it to employ Employees with visas or permits, as indicated in the Employee Information, who accept Offers. The Effective Hire Date for Employees is (x) the Employee Transfer Date for those Employees other than Inactive Employees, and (y) 12:01 a.m. on the first (1^st) Business Day following the release to return to active employment from leave for all Inactive Employees and on which such Inactive Employee reports to work with the Purchaser or Designated Purchaser. Unless otherwise expressly provided, as of the Effective Hire Date for a period of not less than twelve (12) months after the Closing Date, the employment of Employees shall be on the terms and conditions set forth in Section 7.1, including any applicable schedules thereto.

7.1.2 Employee Benefits.

(a) The Purchaser or a Designated Purchaser shall, and shall cause its relevant Affiliates to, except as otherwise provided herein, recognize the service date of each Transferred Employee as set out in the Employee Information for all purposes, other than (x) benefit accrual or (y) otherwise for determination of the amount or duration of benefits under any defined benefit pension plan or equity incentive plan, to the extent that each such Transferred Employee was entitled to recognition of such service date under the corresponding Seller Employee Plan in which such Transferred Employee participated or was eligible to participate (including any Seller Employee Plan that is suspended or the benefits of which are suspended), and to the extent that such recognition would not result in a duplication of benefits or the funding thereof.

(b) After the date hereof, the Sellers and the Purchaser shall cooperate promptly and in good faith in preparing the transition of the Transferred Employees (and their eligible dependents, as applicable) from coverage under the Seller Employee Plans to coverage under the Purchaser Employee Plans effective as of the Transferred Employee’s Effective Hire Date. Except with respect to any Employee whose benefits are specified by applicable Law, the Purchaser or the relevant Purchaser’s Affiliates shall use reasonable best efforts to cause each Transferred Employee (and their eligible dependents, as applicable) to be eligible as of the relevant Effective Hire Date to participate in and accrue benefits under the Purchaser Employee Plans, in each case under the terms of such Purchaser Employee Plans. Notwithstanding the foregoing, for a period of twelve (12) months following the Closing Date, Purchaser shall, or cause its relevant Affiliate to, provide Transferred Employees with employee benefits substantially comparable, in the aggregate, to the employee benefits (other than benefits under (i) the KEIP, (ii) the KERP or (iii) the Nortel Special Incentive Plan, retiree medical benefits, equity based compensation or defined benefit pension benefits) provided to such Transferred Employees under Seller Employee Plans set forth on Section 4.11(a) of the Sellers Disclosure Schedule and as required by applicable Law prior to the Closing.

(c) Without limiting the generality of the foregoing, the Purchaser shall, or shall cause its relevant Affiliates to, provide the following benefits to Transferred Employees:

(i) For the period beginning on the Closing Date and ending on the date that is nine (9) months from the Closing Date, the Purchaser shall, or shall cause its relevant Affiliates to, provide Transferred Employees with the severance payments to which the Transferred Employee would have been entitled to under

112

the applicable Seller Employee Plan covering the Transferred Employee in effect immediately prior to the Effective Hire Date.

(ii) Section 7.1.2(c)(ii) of the Sellers Disclosure Schedule will set forth the amount of accrued and unused vacation days that are due and owing to the Transferred Employees as of the date hereof and such amount shall be updated by the Sellers as of the Closing Date. The Purchaser shall, or shall cause its relevant Affiliates to, grant each Transferred Employee paid time off in an amount equal to such accrued unused vacation days set forth for such Transferred Employee in the applicable Section of the Sellers Disclosure Schedule. If such Transferred Employee terminates employment with the Purchaser or an Affiliate of the Purchaser prior to receiving such paid time off, as described above, the Purchaser shall pay such Transferred Employee an amount equal to any such unused paid time off upon such employment termination.

(iii) The vacation accrual rate and maximum accrual of each Transferred Employee on and after the Effective Hire Date shall be determined under the vacation policy of the Purchaser or its relevant Affiliate following the crediting of such Transferred Employee with service as provided in Section 7.1.2(a). For the avoidance of doubt, such vacation accrual rate and maximum accrual applicable to Transferred Employees whose accrued vacation is specified in Section 7.1.2(c)(ii) of the Sellers Disclosure Schedule shall not be decreased prior to the date which is twelve (12) months following the Closing Date, or later if required by applicable Law, by the Purchaser or its Affiliates as a result of the obligation in Section 7.1.2(c)(ii) that Purchaser or its Affiliates grant or compensate such Employees with respect to accrued and unused vacation days due and owing as of the Effective Hire Date.

(iv) The Purchaser or Designated Purchaser shall provide each Transferred Employee employed in Australia with the benefit of the amount set forth on Section 7.1.2(c)(iv) of the Sellers Disclosure Schedule of long service leave and sick leave, at such time, if any, as payment of such amount is due and owing to each such Transferred Employee under applicable Law, taking into account in the calculation of such payment the service of such Transferred Employee as set forth in the Employee Information and such Transferred Employee’s service with the Purchaser on and after the Closing Date. Section 7.1.2(c)(iv) of the Sellers Disclosure Schedule shall be updated as of the Closing Date to reflect employee hiring, promotions, demotions, transfers or other status changes and attrition, and further accruals or reductions or other changes from the date hereof to the Closing Date, in each case if and only to the extent permitted under Section 5.9.

(v) For the avoidance of doubt, Inactive Employees, as of the Closing Date will be listed on Section 7.1.2(c)(ii) of the Sellers Disclosure Schedule and Section 7.1.2(c)(iv) of the Sellers Disclosure Schedule, as applicable; provided, however, that unless and until such Inactive Employees become Transferred

113

Employees, the Purchaser shall have no obligation with respect to Inactive Employees under this Section 7.1.2(c).

(d) With respect to each Transferred Employee (and their eligible dependents, as applicable), the Purchaser or the relevant Purchaser’s Affiliates shall use reasonable best efforts to cause the Purchaser Employee Plans to (i) waive any eligibility periods, evidence of insurability or pre-existing condition limitations and (ii) honor any deductibles, co-payments, co-insurance or out-of-pocket expenses paid or incurred by such employees, including with respect to their dependents, under comparable Seller Employee Plans during the Purchaser Employee Plan year in which the relevant Effective Hire Date occurs, in each case to the extent waived, inapplicable to such Transferred Employee, or honored under the Seller Employee Plans in which such Transferred Employee participated immediately prior to the Closing and to the extent doing so will not result in the duplication of benefits; provided, that such Transferred Employee provides an explanation of benefits or similar documentation, as reasonably required by the Purchaser, of any expenses paid or incurred to the Purchaser or its Affiliates. Nothing in this paragraph or otherwise in this Article VII shall be construed as constituting an amendment of any employee benefit plan.

(e) As of the Closing Date, the Purchaser or a Designated Purchaser shall establish or otherwise provide a registered pension plan for Transferred Employees employed in Canada and maintain such plan for a period of at least five (5) years following the Closing Date, or such shorter period as may be required or dictated by applicable Law and each such Transferred Employee’s participation shall commence on such Transferred Employee’s Employee Transfer Date.

(f) The Sellers shall be solely responsible for any required notice under the WARN Act with respect to terminations of employment of Employees that occur on or prior to the Closing Date and for any individual who does not become a Transferred Employee regardless of the date of termination; provided, that the Purchaser or Designated Purchaser, as applicable, has satisfied its obligations as set out in this Article VII. The Purchaser shall be solely responsible for any required notice under the WARN Act with respect to terminations of employment of Transferred Employees that occur after the Closing Date. On the Closing Date, the Sellers shall provide to the Purchaser, in writing, the number of Employees, by facility and operating unit, who have experienced an “employment loss” (as defined under the WARN Act) during the ninety (90) days prior to Closing.

(g) Nothing express or implied in this Agreement (including anything set forth in this Section 7.1) restricts the right of the Purchaser or any Designated Purchaser to terminate the employment of any Transferred Employee after the Closing, to modify the compensation or employee benefits of any Transferred Employee or relocate any Transferred Employee’s principal place of employment; provided any such termination, modification or relocation is effected in accordance with applicable Law and the terms and conditions of this Section 7.1.

SECTION 7.2 Employment Obligations with Respect to Union Employees. The provisions of this Section 7.2 shall apply to Union Employees

114

(a) As of the Closing Date, the Purchaser or its relevant Affiliate will be bound by the terms and obligations of the Collective Labor Agreements specified in the Employee Information with respect to the employment of the relevant Union Employees as a successor, assign or purchaser of the relevant Seller and shall employ the Union Employees in accordance therewith. Notwithstanding anything to the contrary herein, nothing in this Section 7.2 shall be deemed to preclude the Purchaser or the relevant Affiliates from renegotiating the terms of any Collective Labor Agreement after the Closing Date.

(b) During the period beginning on the later of (i) the approval of the U.S. Sale Order and (ii) the Canadian Approval and Vesting Order, and ending on the Closing Date, unless otherwise specifically required by applicable Law, the Sellers shall not limit the Purchaser or the Designated Purchasers’ ability to contact and communicate with the unions or any collective bargaining agents that are parties to the Collective Labor Agreements listed in Section 4.11(d) of the Sellers Disclosure Schedule. For the avoidance of doubt, unless otherwise specifically required by applicable Law, the Sellers shall not limit the Purchaser or the Designated Purchasers’ ability to negotiate with the union or any collective bargaining agent regarding the terms and conditions of employment with respect to the Union Employees; provided, however, that (i) the Purchaser or the Designated Purchasers shall not negotiate directly or indirectly with any Union Employee who is not a recognized representative of a union or a member of the union's collective bargaining team, (ii) the Purchaser or Designated Purchaser shall provide, upon the Sellers’ reasonable request, updated information regarding the Purchaser’s or Designated Purchaser’s contact and communication with the unions or collective bargaining agent, as applicable, and the status of any such negotiations, (iii) the Purchaser or the Designated Purchasers shall not bind or purport to bind any of the Sellers to any amendment to any collective agreement or any other agreement with any union, and (iv) any changes that the Purchaser or the Designated Purchasers may negotiate with a union shall be conditional upon and only take effect following Closing.

SECTION 7.3 Excluded Employee Liabilities. For purposes of clarity, the Sellers shall retain, and neither the Purchaser, any of the Designated Purchasers nor any Purchaser Employee Plan shall assume at the Closing, any of the following Liabilities of the Sellers, their Affiliates or Seller Employee Plans (the “Excluded Employee Liabilities”):

(a) any Liabilities related to Seller Employee Plans or any employee plans or arrangements related to employees of the Business employed by the Sellers, including the Sellers’, any of their Affiliates’ or Seller Employee Plans’ obligations to contribute to, make payments or provide benefits under any Seller Employee Plan except with respect to any payments or benefits provided for in Section 2.1.3(h);

(b) any obligation to provide continuation coverage pursuant to COBRA or any similar Law under any Seller Employee Plan that is a “group health plan” (as defined in Section 5000(b)(1) of the Code) to any Transferred Employees and/or their qualified beneficiaries who have a COBRA qualifying event that occurs prior to such Employees’ Effective Hire Date;

115

(c) any Liabilities resulting from any Action (i) by any Employee relating to his/her employment or termination of employment with any of the Sellers, except any Action related to the Purchaser’s failure to perform its obligations under this Article VII, or (ii) by an applicant with respect to potential employment with any of the Sellers in the Acquired Business.

(d) any other Liabilities for former employees, Employees and independent contractors related to the Acquired Business that are not Transferred Employees;

(e) any Liability with respect to the KERP, the KEIP, the Nortel Special Incentive Plan, the Nortel Networks Negotiated Pension Plan, or any other retention plan, program or arrangement of the Sellers that provides benefits to any Transferred Employee; and

(f) any Liability of the Sellers or any ERISA Affiliate under Title IV of ERISA.

SECTION 7.4 Other Employee Covenants.

(a) After the date hereof, and subject to each Party’s disclosure obligations imposed by Law or by Government Entities and each Party’s obligations hereunder, the Parties shall not, and shall procure that each of their Affiliates shall not, issue any announcement or communication to their respective employees or the Employees, prior to consultation with, and the approval of, the other Party (not to be unreasonably withheld or delayed) with respect to this Agreement or any of the transactions contemplated hereby (including any announcement or communication to any individual employee that the Purchaser is required to provide under applicable Law). Each Party shall cooperate in respect of the development and distribution of any announcement and communication to the employees of the other Party including Employees thereof, with respect to this Agreement or any of the transactions contemplated hereby.

(b) The Purchaser undertakes to keep the Employee Information in confidence and that, until the relevant Employee Transfer Date with respect to those Employees who become Transferred Employees, and at all times with respect to those Employees who do not become Transferred Employees:

(i) the Purchaser shall, and shall cause the Designated Purchasers to, restrict the disclosure of the Employee Information only to such of its employees, agents and advisors as is reasonably appropriate for the purposes of complying with its obligations pursuant to this Agreement, and the Employee Information shall not be disclosed to any other Person without the consent of the Main Sellers, such consent not to be unreasonably withheld;

(ii) the Employee Information shall not be used except for the purposes of complying with the obligations of the Purchaser and the Designated Purchasers pursuant to this Agreement, and for the purposes reasonably related to the same, and shall be returned to the Sellers or destroyed, at the Sellers’ election, if this Agreement is terminated; and

116

(iii) the Purchaser shall, and shall cause the Designated Purchasers to, comply with such additional obligations as may be reasonably required in any particular jurisdiction to comply with any applicable data privacy Laws.

(c) The Purchaser and the Sellers shall cooperate with each other in order to provide for an orderly transition of the Transferred Employees from the Sellers to the Purchaser or the Designated Purchasers, as applicable, and to minimize the disruption to the respective businesses of the Parties resulting from the transactions contemplated hereby.

(d) During the Non-Solicitation Period the Sellers shall not, and shall not permit, cause or encourage any of their Affiliates to, without the advance written consent of the Purchaser, either directly or indirectly solicit for employment, hire or otherwise engage to provide services any Transferred Employee or other employee of the Purchaser or Designated Purchaser unless the Purchaser or a Designated Purchaser involuntarily terminate the employment of such employee, without cause, prior to such action by the Sellers; provided, however, that nothing in this Section 7.4(d) shall prevent the Sellers from conducting generalized employment searches, including placing bona fide public advertisements, that are not specifically targeted at such Transferred Employees or other employees of the Purchaser or Designated Purchaser and hiring such Transferred Employees or other employees of the Purchaser or Designated Purchaser identified through such employment searches. During the Non-Solicitation Period, the Purchaser and the Designated Purchasers shall not, and shall not permit, cause or encourage any of their Affiliates to, without the Seller’s advance written consent, either directly or indirectly solicit for employment, hire or otherwise engage to provide services (i) any of the employees of the Sellers (other than Employees), unless the Sellers involuntarily terminate the employment of such employee, without cause, prior to such action by the Purchaser or the Designated Purchasers or as otherwise permitted by the Transition Services Agreement, or (ii) any Employees who have rejected an Offer of the Purchaser or a Designated Purchasers or objected to their transfer of employment to the Purchaser or a Designated Purchasers pursuant to this Agreement or Employees to whom the Purchaser or a Designated Purchaser did not make a compliant Offer pursuant to Section 7.1.1; provided, however, that nothing in this Section 7.4(d) shall prevent the Purchaser or the Designated Purchasers from conducting generalized employment searches, including placing bona fide public advertisements, that are not specifically targeted at such employees or former employees of the Sellers and hiring such employees or former employees of the Sellers identified through such employment searches.

(e) As of the Effective Hire Date, the Sellers and their Affiliates shall release any non-competition or confidentiality obligations in respect of the Acquired Business or Assets binding to the Transferred Employees which would survive the termination of the employment relationship between the Sellers and the Transferred Employees. For the avoidance of doubt, this release shall operate only to facilitate the Transferred Employees’ employment with the Purchaser or a Designated Purchaser, as applicable, in the Acquired Business and the subject non-competition and confidentiality obligations shall remain in full force and effect as to all other aspects of the Sellers’ business and all other Persons.

(f) Each Party shall reasonably cooperate to communicate relevant information to Employees relating to this Agreement and the transactions contemplated hereunder, and shall provide copies of all notices required by Law and related to the transactions

117

contemplated by this Agreement to the other Party. Each Party shall provide copies of such communications to the other Party reasonably in advance of distribution, and shall provide an opportunity for such other Party to comment.

(g) In the event and for so long as the Seller is actively contesting or defending against any third party Action or Claim in which the Employee Records are pertinent, the Purchaser or Designated Purchaser agrees to provide reasonable access to Employee Records solely for the purposes of such Action or Claim, at the cost of the Sellers.

(h) The Sellers shall use reasonable efforts to provide updated Employee Information to the Purchaser on the first Business Day of each month beginning after the date hereof and shall provide the Purchaser with the final updated Employee Information with respect to Employees ten (10) Business Days prior to the Closing Date in order to reflect Employee hiring, promotions, demotions, transfers, or other status changes and attrition, and further accruals or reductions or, if and to the extent applicable to such schedule, other changes in each Employee’s compensation from the date hereof to the Closing Date, in each case if and only to the extent permitted under Section 5.9.

SECTION 7.5 Sole Benefit of the Sellers and the Purchaser or Designated Purchaser. The terms and provisions of this Article VII are for the sole benefit of the Sellers and the Purchaser or Designated Purchaser. Nothing contained herein, express or implied (i) shall be construed to establish, amend, or modify any Seller Employee Plan, any Purchaser Employee Plan, or any other benefit plan, program, agreement or arrangement, (ii) shall alter or limit the ability of the Purchaser or Designated Purchaser, the Sellers, or any of their respective Affiliates to amend, modify or terminate any Seller Employee Plan, any Purchaser Employee Plan (other than as provided in Section 7.1.2(E), or any other benefit or employment plan, program, agreement or arrangement after the Closing Date, (iii) is intended to confer or shall confer upon any current or former employee any right to employment or continued employment, or constitute or create an employment agreement with any Transferred Employee, or (iv) is intended to confer or shall confer upon any individual or any legal representative of any individual (including employees, retirees, or dependents or beneficiaries of employees or retirees and including collective bargaining agents or representatives) any right as a third-party beneficiary of this Agreement.

SECTION 10.8 Exhibits; Sellers Disclosure Schedule.

(a) The Sellers Disclosure Schedule and the Exhibits attached hereto constitute a part of this Agreement and are incorporated into this Agreement for all purposes as if fully set forth herein.

(b) For purposes of the representations and warranties of the Sellers contained in this Agreement, disclosure in any section of the Sellers Disclosure Schedule of any facts or circumstances shall be deemed to be adequate response and disclosure of such facts or circumstances with respect to all representations or warranties by the Sellers calling for disclosure of such information, whether or not such disclosure is specifically associated with or purports to respond to one or more of such representations or warranties, if it is reasonably apparent from the Sellers Disclosure Schedule that such disclosure is applicable. The inclusion of any information in any section of the Sellers Disclosure Schedule or other document delivered by the Sellers pursuant to this Agreement shall not be deemed to be an admission or evidence of the materiality of such item, nor that such item could have a Material Adverse Effect, nor shall it establish a standard of materiality for any purpose whatsoever.

SECTION 10.9 Counterparts. The Parties may execute this Agreement in two or more counterparts (no one of which need contain the signatures of all Parties), each of which will be an original and all of which together will constitute one and the same instrument.

SECTION 10.10 No Presumption. The Parties agree that this Agreement was negotiated fairly between them at arm’s length and that the final terms of this Agreement are the product of the Parties’ negotiations. Each Party represents and warrants that it has sought and received experienced legal counsel of its own choosing with regard to the contents of this Agreement and the rights and obligations affected hereby. The Parties agree that this Agreement shall be deemed to have been jointly and equally drafted by them, and that the provisions of this Agreement therefore should not be construed against a Party on the grounds that such Party drafted or was more responsible for drafting the provisions.

SECTION 10.11 Severability. If any provision, clause, or part of this Agreement, or the application thereof under certain circumstances, is held invalid, illegal or incapable of being enforced in any jurisdiction, (i) as to such jurisdiction, the remainder of this Agreement or the application of such provision, clause or part under other circumstances, and (ii) as for any other jurisdiction, all provisions of this Agreement, shall not be affected and shall remain in full force and effect, unless, in each case, such invalidity, illegality or unenforceability in such jurisdiction materially impairs the ability of the Parties to consummate the transactions contemplated by this Agreement. Upon such determination that any clause or other provision is invalid, illegal or incapable of being enforced in such jurisdiction, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible even in such jurisdiction.

128

SECTION 10.12 Headings. The headings used in this Agreement are for the purpose of reference only and shall not affect the meaning or interpretation of any provision of this Agreement.

SECTION 10.13 Entire Agreement.

(a) This Agreement, the other Transaction Documents, the Confidentiality Agreement and the Clean Team Confidentiality Agreement together set forth the entire understanding of the Parties relating to the subject matter thereof, and all prior or contemporaneous understandings, agreements, representations and warranties, whether written or oral, are superseded by this Agreement, the other Transaction Documents, the Confidentiality Agreement and the Clean Team Confidentiality Agreement, and all such prior or contemporaneous understandings, agreements, representations and warranties are hereby terminated. In the event of any irreconcilable conflict between this Agreement and any other Transaction Documents, the Confidentiality Agreement or the Clean Team Confidentiality Agreement, the provisions of this Agreement shall prevail, regardless of the fact that certain other Transaction Documents, such as the Local Sale Agreements, may be subject to different governing Laws.

(b) For the sake of clarity, the provisions of the EMEA Asset Sale Agreement have been drafted separately from the provisions in the body of this Agreement to reflect differing market practices in the countries of jurisdiction of the EMEA Sellers. Unless the context specifically requires, the provisions contained in the body of this Agreement and the provisions of the EMEA Asset Sale Agreement shall be interpreted independently and without reference to each other.

SECTION 10.14 Availability of Equitable Relief; Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, subject to the limitations set forth in this Section 10.14, each of the Parties shall, without the posting of bond or other security (any requirement for which the Parties hereby waive), be entitled to equitable relief to prevent or remedy breaches of this Agreement, without the proof of actual damages, including in the form of an injunction or injunctions or orders for specific performance in respect of such breaches. Each Party agrees to waive any requirement for the security or posting of any bond in connection with any such equitable remedy. Each Party further agrees that the only permitted objections that it may raise in response to any action for such equitable relief is that it contests the existence of a breach or threatened breach of the provisions of this Agreement or that equitable relief is not permitted pursuant to this Section 10.14, and no Party will allege, and each Party hereby waives the defense or counterclaim, that there is an adequate remedy at Law except as expressly provided in this Section 10.14. For the avoidance of doubt, the Parties agree that specific performance shall not constitute the sole and exclusive remedy of the Parties, whether at Law or equity, for any and all breaches after Closing of the terms and conditions of this Agreement. In no event shall any Party be liable for special, exemplary, consequential or punitive damages.
