(ii) Section 2.1.5(b)(ii) of the Sellers Disclosure Schedule sets forth
a list of all 365 Real Estate Leases that the Purchaser has elected to have the relevant U.S. Debtor pursuant to section 365 of the U.S. Bankruptcy Code assume and assign to the Purchaser or a Designated Purchaser at Closing. Such designated 365
Real Estate Leases (together with any additional 365 Real Estate Leases the Purchaser has elected to have assumed and assigned pursuant to Section 2.1.5(b)(iv), are referred to herein as the Designated 365 Real Estate
Leases).

(iii) Section 2.1.5(b)(iii) of the Sellers Disclosure Schedule sets forth a list of
all 365 Real Estate Leases that the Purchaser has elected to have the relevant U.S. Debtor, pursuant to section 365 of the U.S. Bankruptcy Code, assume and under which the Purchaser or a Designated Purchaser will enter into a Sublease (as defined in
Section 5.28) in accordance with the terms of the related 365 Real Estate Lease (together with any additional 365 Real Estate Leases the Purchaser has elected to have assumed and subleased pursuant to Section 2.1.5(b)(iv), the
Assumed and Subleased Real Estate Leases) at Closing, with each such Sublease to have a term to expire as specified in Section 5.28. Notwithstanding the foregoing, the 365 Real Estate Lease identified in
Section 2.1.5(b)(iii) of the Sellers Disclosure Schedule as Lease A shall constitute an Assumed and Subleased Real Estate Lease only if Seller does not enter into Replacement Lease A at or prior to Closing. Purchaser shall have the right to
make the election in Section 2.1.5(b)(v) with respect to the 365 Real Estate Lease identified in Section 2.1.5(b)(iii) of the Sellers Disclosure Schedule as Lease B.

(iv) It is understood and agreed that, following the date of this Agreement but prior to the applicable Contract Designation
Date, the Purchaser shall be entitled to, by written notice to NNI:

(A) designate additional 365 Real Estate
Leases for assumption by the relevant U.S. Debtors and assignment to the Purchaser or Designated Purchaser at Closing solely from the list of 365 Real Estate Leases set forth in Section 2.1.5(b)(iv) of the Sellers Disclosure Schedule that are
designated for Assignment;

(B) designate additional 365 Real Estate Leases for assumption by the
relevant U.S. Debtors and entry into a Sublease with the Purchaser or Designated Purchaser at Closing solely from the list of 365 Real Estate Leases set forth in Section 2.1.5(b)(iv) of the Sellers Disclosure Schedule that are designated for
Sublease; and

(C) elect to remove entirely (but not to change the designation from an Assumed and
Subleased Real Estate Lease to a Designated 365 Real Estate Lease or vice versa) any 365 Real Estate Lease which had therefore been set forth in Section 2.1.5(b)(ii) of the Sellers Disclosure Schedule so that neither Purchaser nor any
Designated Purchaser shall



56



---

have any further obligation to accept an assignment or sublease thereof at Closing.

Subsequent to the Contract Designation Date, the Purchaser shall have no right to designate additional 365 Real Estate Leases for assumption by the relevant U.S. Debtors and assignment to or entry into a
Sublease with the Purchaser or Designated Purchaser at Closing or to remove any 365 Real Estate Leases which had previously been designated by Purchaser for assumption or sublease under this Section 2.1.5(b), without the prior written consent
of NNI.

(v) Purchaser shall be obligated to enter into a Sublease with respect to that portion of Lease B
indicated on Exhibit 2.1.5(b)(v), unless in lieu of entering into such Sublease, Purchaser elects, by written notice delivered to NNI on or prior to the date that is thirty (30) days following the date of this Agreement, either
(A) to take an assignment at Closing, either by itself or through a Designated Purchaser, of such Lease B in its entirety, or (B) to remove all Assets, Employees and operations relating to the Business from the premises covered by such
Lease B, in which event Purchaser will not be required to take an assignment of Lease B or enter into a Sublease thereunder at the Closing and Lease B will no longer be deemed a Mission Critical Lease for any purpose under this Agreement. Purchaser
shall be obligated to complete the removal of all such Assets, Employees and operations from such premises no later than March 30, 2010, and the Sellers agree that notwithstanding the provisions of Section 5.31 hereof, the Sellers will not
reject Lease B in advance of such removal provided such removal has been completed no later than March 30, 2010. The parties shall convene to discuss and agree on a mutually acceptable strategy for negotiating a Temporary Lease or an Equivalent
Lease for Equivalent Space subject to the principles of Section 5.31(g)(ii) and 5.31(g)(iii) (except that the Purchaser will be responsible for all Relocation Costs and the rent and occupancy costs under any Temporary Lease or Equivalent
Lease). All costs relating to such removal, including but not limited to Relocation Costs, shall be borne exclusively by Purchaser such that neither any Seller nor any Affiliate of a Seller shall have liability as a result of such election by
Purchaser. Purchaser shall be obligated to pay Sellers, prior to the dates on which such sums are due to the relevant landlord, one hundred percent (100%) of the relevant Sellers actual, out of pocket rent and other occupancy costs under
Lease B, with respect to all space (regardless of whether all such space is used by the Business as of the date of this Agreement) subject to such Lease B other than that space which is subject as of the date of this Agreement to a sublease with the
relevant Seller as sublandlord thereunder, from the Closing Date through the date on which Purchaser has completed its removal of all such Assets, Transferred Employees and operations and left such premises in broom clean condition. Purchasers
occupancy of such premises following Closing for the purpose of removing Assets, Transferred Employees and operations shall be pursuant to the terms of a customary form of license agreement reasonably acceptable to the Purchaser and Sellers and, to
the extent that the relevant landlords Consent is required under such Lease B to the granting



57



---

of such license, the applicable provisions of Section 5.16(a)(iii) shall govern the rights and obligations of Purchaser, any Designated Purchaser and Sellers.

(vi) It is understood and agreed that, other than as expressly permitted in Section 2.1.5(b)(iv)(C), the Purchaser shall
be obligated to accept assignment of all Designated 365 Real Estate Leases and enter into Subleases of all Assumed and Subleased Real Estate Leases.

(vii) Notwithstanding the foregoing and subject to the terms of Section 5.31 and Section 5.32, the Sellers obligation to make 365 Real Estate Leases available for designation by the
Purchaser pursuant to this Section 2.1.5(b)(vii) shall be subject to the Sellers right in all instances to reject such leases pursuant to the U.S. Bankruptcy Code in accordance with the terms of Section 5.31 and the Sellers
right in all instances to restructure such leases in accordance with the terms of Section 5.32.

relevant Seller assign to the Purchaser or a Designated Purchaser (such Contracts on the Non-365 SI/SP Contract List shall be collectively referred to as the Rejected Non-365 SI/SP Contracts). In accordance with applicable Law and
subject to the provisions of the Clean Team Confidentiality Agreement and the Confidentiality Agreement, the Sellers have used their reasonable best efforts to (x) make available to the Purchaser in the Data Room or to appropriate Clean Team
Members all material documentation that forms part of the Non-365 SI/SP Contracts and (y) provide in the Data Room or to appropriate Clean Team Members all information about such Contracts that the Purchaser had previously reasonably requested

than (30) days from the date hereof, the Sellers shall prepare a list (to be updated each seven (7) days thereafter) (the Other Non-365 Contract List) of all the Other Contracts that are not Other 365 Contracts
(Contracts that may be included on the Other Non-365 Contract List, the Other Non-365 Contracts). In accordance with applicable Law and subject to the provisions of the Clean Team Confidentiality Agreement and the Confidentiality

Contracts, shall not be Assigned Contracts hereunder and all Liabilities thereunder shall be Excluded Liabilities.

(v) Subsequent to the relevant Contract Designation Date, the Purchaser shall not have the right to make or change any designation of Designated Non-365 SI/SP Contracts, Designated Other Non-365
Contracts, Rejected Pre-Signing Customer Contracts or Rejected Post-Signing Customer Contracts without the prior written consent of the Main Sellers, which shall not be unreasonably withheld.

forth a list of the Non-365 Real Estate Leases with respect to which the Purchaser has elected to have the relevant Seller enter into a Sublease (as defined in Section 5.28) with the Purchaser or a Designated Purchaser (together with any

the relevant Lease, with each such Sublease to have a term to expire as specified in Section 5.28.

(iv)
It is understood and agreed that, following the date of this Agreement but prior to the applicable Contract Designation Date, the Purchaser shall be entitled to, by written notice to the Main Sellers:

(A) designate additional Non-365 Real Estate Leases for assignment to the Purchaser or Designated Purchaser at Closing
solely from the list of Non-365 Real Estate Leases set forth in Section 2.1.6(b)(iv) of the Sellers Disclosure Schedule that are designated for Assignment;

(B) designate additional Non-365 Real Estate Leases for entry into a Sublease with the Purchaser or Designated Purchaser at
Closing solely from the list of Non-365 Real Estate Leases set forth in Section 2.1.6(b)(iv) of the Sellers Disclosure Schedule that are designated for Sublease; and

(C) elect to remove entirely (but not to change the designation from a Non-365 Subleased Real Estate Lease to a Designated
Non-365 Real Estate Lease or vice versa) any Non-365 Real Estate Lease which had therefore been set forth in either Section 2.1.6(b)(ii) or 2.1.6(b)(iii) of the Sellers Disclosure Schedule so that Purchaser shall have no further obligation to
accept an assignment or sublease thereof at Closing.

Subsequent to the Contract Designation Date, the Purchaser shall have no
right to designate additional Non-365 Real Estate Leases for assignment to or entry into a Sublease with the Purchaser or Designated Purchaser at Closing or to remove any Non-365 Real Estate Lease which had previously been designated by Purchaser

Section 5.28 with the relevant Seller under each of the Non-365 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 Designated 365 Contracts and the Designated Non-365 Contracts in force as of the Closing Date, the change of control of the tenant under any Company Leases in force as of the Closing Date and the entry into the Subleases
and the Lease A Sublease; 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 and provided further that the Purchaser shall comply with the requirements set forth in Section 5.4 of the Sellers Disclosure Schedule in connection therewith. 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 before the fifteenth (15th) day after the execution of this Agreement, the Sellers shall provide to the Purchaser a good faith
estimate of the amount of the Cure Cost for each 365 Real Estate Lease or Non-365 Real Estate Lease listed of the date hereof on Sections 2.1.5(b)(ii), 2.1.5(b)(iii), 2.1.6(b)(ii) or 2.1.6(b)(iii) of the Sellers Disclosure Schedule, provided that
the Sellers may supplement such estimate as further information is received from landlords.

in no event later than fifteen (15) Business Days from the date hereof, representatives of the Sellers and the Purchaser shall meet to discuss, subject to applicable Law (including any applicable Antitrust Law), Purchasers post-Closing
strategy with respect to the assignment, novation, termination or rejection of the Other Contracts of the Business. Within five (5) Business Days after such meeting, subject to the Main Sellers compliance with subparts (x) and (y) of
Sections 2.1.5(a)(ii) and 2.1.6(a)(ii), the Purchaser shall provide to the Main Sellers a list of those suppliers of the Business that are party to Other Contracts that the Purchaser may wish to have assigned to the Purchaser or a Designated
Purchaser at Closing (the Selected Suppliers). The Purchaser shall be entitled to supplement the list of Selected Suppliers by written notice to the Main Sellers within the following thirty (30) Business Days. On or before
the thirtieth (30th) day after the date when the Purchaser delivers to the Main Sellers the list of Selected Suppliers (or a supplement thereto) in accordance with the previous sentences, the Main Sellers shall provide to the Purchaser a good
faith estimate of the amount of the Cure Cost aggregated for each Selected Supplier under the Other Contracts with each Selected Supplier, as of the date thereof. If, subsequent to the delivery of such good faith estimates, it is determined that the
Cure Costs under the Other Contracts with a Selected Supplier exceed by more than ten percent (10%) the good faith estimate provided by the Main

Sellers to the Purchaser, the Contract Designation Date for such Other Contracts shall be extended pursuant to clause (a) of the definition of Contract Designation Date.

(c) To the extent that the assumption and assignment of any 365 Customer Contract or 365 SI/SP 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
Assumed and Assigned Contract (other than a 365 Customer Contract or 365 SI/SP Contract) entails the payment of any Cure Cost, the Purchaser shall directly 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 and such payment shall not entitle the Purchaser to any adjustment to the Purchase Price.

(d) To the extent that assignment to the Purchaser or a Designated Purchaser of any Non-365 Customer Contract or Non-365 SI/SP 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 Non-365 SI/SP Contract or an Assumed and Assigned Contract entails the payment of Cure Costs, the Purchaser shall pay such amounts directly to
such contracting party in a manner agreed between the Purchaser and such contracting party or ordered by a court of competent jurisdiction, and such payment shall not entitle the Purchaser to any adjustment to the Purchase Price.

(e) To the extent that entry into a Sublease with the Purchaser or a Designated Purchaser of any Assumed and Subleased Real Estate Lease or
Non-365 Subleased Real Estate Lease 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 to the overall rentable square footage of
the premises demised under such Assumed and Subleased Real Estate Lease or Non-365 Subleased 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 and 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 (or, at the election of Purchaser, Purchaser shall be entitled to pay the entirety of such Cure Costs and receive an adjustment to the Purchase Price for the Cure Costs paid on Sellers behalf). In the case
of any Cure Costs relating to any Non-365 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 assume 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; provided, however, that the Purchaser may, subject to the conditions set forth herein (and other than with respect to a



62



---

Real Estate Lease, Customer Contract or SI/SP Contract), elect to forego performing such actions and incurring such costs and expenses, in which case the relevant Assumed and Assigned Contract
shall be deemed a Non-Assigned Contract at Closing and all liabilities thereunder shall be Excluded Liabilities.

(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 Designated 365 Contracts and the Designated Non-365 Contracts in force as of the Closing Date and the entry into Subleases; 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 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, for greater
certainty, 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 or desirable 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 a sale agreement and quit-claim deed for the
Owned Real Estate (but only in the event that Purchaser exercises its election under Section 2.1.1 to include the Owned Real Estate among the Assets) and 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 countries
where such Local Sale Agreements are required or desirable, and (ii) the assumption by the Designated Purchasers of any Assumed Liability that the Purchaser intends to allocate to them.

2.1.9. EMEA Asset Sale Agreement. Except as expressly set forth in Sections 2.2, 5.26, 9.2, 9.3, 9.4, 10.14, 10.17 and 10.19 and (in
the case of NNUK and Nortel Networks (Ireland) Limited only) Section 5.36, none of the EMEA Sellers, the Joint Administrators or the Joint Israeli 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 in any manner whatsoever. The only assets, rights, properties and Liabilities of the EMEA Sellers 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.

2.1.10. Non-Assignable Assets. Notwithstanding anything in this Agreement to the contrary, if the requisite Consent 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 the Consent of a third party (including a Government Entity), would constitute a breach, default,



63



---

violation or other contravention of the rights of such third party or would be ineffective with respect to any party to a Contract concerning such Asset. For greater certainty, 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.

Statement delivered by the Main Sellers and the EMEA Sellers. Matters included in the calculations in the Closing Statement to which the Purchaser does not object in the Disagreement Notice shall be deemed accepted by the Purchaser 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 Main Sellers and the EMEA Sellers shall, promptly
upon request, provide the Purchaser, the Designated Purchasers and their respective accountants reasonable access to the books, records, documents, schedules, workpapers and personnel of the Main Sellers and the EMEA Sellers in connection with the

cooperate in any reasonable efforts and requests that would enable otherwise required disclosure to the Purchaser, the Designated Purchasers or their respective representatives to occur without so jeopardizing privilege). 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 Purchaser, 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 or



67

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 Partys 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

2.2.7. Purchase Price Allocation.

(a) The Parties and the EMEA Sellers shall (i) first allocate to the tangible Assets a proportion of the Purchase Price (and, to the
extent properly taken into account under the applicable Tax Laws, the Assumed Liabilities, and after reducing such Purchase Price by the $10 million reduction for transition services described in Section 5.36(c)), equal to the net book value of
such 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 tangible Assets and intangible Assets as the Parties and the EMEA Sellers may agree.

(b) To the extent necessary to file Transfer Tax Returns, or to implement a Section 338(h)(10) Election or a Loss Duplication
Election (if such an election is made), the Parties shall negotiate in good faith to determine an allocation of the Purchase Price, less the $10 million reduction for transition services described in Section 5.36(c), (and, to the extent
properly taken into account under the applicable Tax Laws, the Assumed Liabilities) among the Assets, the EMEA Assets and the Shares (and, if applicable, the non-compete agreement as set forth in Section 5.33) 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 subject to the principles of Section 2.2.7(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 subject to the principles of Section 2.2.7(a)). 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 6.8(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 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 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, filing and audit of any Transfer Tax Returns) and to a Section 338(h)(10) Election or a Loss Duplication Election. For purposes of this Section 2.2.7(b), the term Parties shall include the EMEA Sellers to the
extent any negotiations or agreement required hereunder concern Transfer Tax Returns.

2.2.8. Accrued Cash-Out Vacation
Escrow Amount. The Sellers shall pay to the Transferred Employees listed on Section 2.2.8 of the Sellers Disclosure Schedule (as updated prior to Closing 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) the accrued but unused vacation amount that is owed as of the
Closing Date (determined in accordance with



74



---

the Calculation Principles) less applicable withholding Taxes and shall timely pay any Taxes required to be withheld or paid to appropriate Government Entities in connection therewith. Upon
certification by an officer of the Sellers to the Purchaser and the Escrow Agent of the actual payment of such amount to such Transferred Employees and withholding and payment of such Taxes in connection therewith, unless the Purchaser reasonably
objects in writing, with copy to the Escrow Agent, to such certification within three (3) Business Days from receipt thereof, NNI and NNL (without the need for joint instructions from the Purchaser) shall direct the Escrow Agent to disburse
funds in the Accrued Cash-Out Vacation Escrow Account to reimburse the Sellers for the amount so certified (not to exceed, in the aggregate, the Accrued Cash-Out Vacation Escrow Amount, together with accrued earnings thereon). Any positive balance
remaining in the Accrued Cash-Out Vacation Escrow Account giving effect to any distributions therefrom made or required to be made as a result of certifications submitted by the Sellers on or before the Accrued Vacation Amount Final Payment Date
shall be transferred to the Purchase Price Adjustment Escrow Account, added to the Purchase Price Adjustment Escrow Amount and applied as provided in Section 2.2.4.

SECTION 2.3. Closing.

2.3.1. Closing Date. The completion of the
purchase and sale of the Assets and the Shares and the assumption of the Assumed Liabilities (the Closing) shall occur simultaneously with closing of the transaction contemplated by the EMEA Asset Sale Agreement and shall take

any actions, undertakings, divestitures, licenses or hold separate or similar arrangements or any arrangements for the conduct of any business and/or terminating any relationships or contractual rights or obligations that, individually or in the

(A) any such access shall be conducted at 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 or Companies
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) the Sellers will not be required to
provide to the Purchaser access to or copies of any Employee Records if the provision of such Employee Records would cause the Sellers to be in contravention of any applicable Law (but shall cooperate in good faith and use reasonable best efforts to
provide Purchaser with the maximum employee information, excluding health and protected status data, allowed by Law), (C) access to information which the Main Sellers reasonably consider to be commercially sensitive shall only be provided to
appropriate Clean Team Members in accordance with applicable Law and subject to the provisions of the Clean Team Confidentiality Agreement and the Confidentiality Agreement, as applicable, and (D) with respect to the NGS Companies, any such

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.

Section 5.4, Section 5.5 and Section 5.36, 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 and in order to obtain any Consent to the transfer of Assets or the assumption of Assumed Liabilities).

(b) The Sellers shall use their reasonable best efforts to make available (in accordance with applicable Law and subject to the provisions
of the Clean Team Confidentiality Agreement and the Confidentiality Agreement), to the Purchaser in the Data Room or to appropriate Clean Team Members, as soon as practicable, all material documentation that forms part of, and all other information
reasonably requested by the Purchaser in writing to enable the Purchaser to review by the relevant Contract Designation Date, the Other 365 Contracts and Other Non-365 Contracts.

otherwise provided in this Agreement or the Transaction Documents, 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)

SECTION 5.11. Confidentiality.

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 to any court or to any liquidator or in connection with any
auction process approved by the Bankruptcy Court and show appropriate figures in their administration records, accounts and returns.

(b) From the Closing Date until the date that is five (5) years after the Closing Date, the Sellers shall not, and shall cause their Affiliates not to, and shall use reasonable best efforts to cause the respective representatives of
the Sellers and their Affiliates not to, use or disclose to any Third Party, any Confidential Information. For purposes of this Agreement,



112



---

Confidential Information consists of all competitively sensitive information and data related to the Business, the Assets and/or the Companies (including Transferred
Intellectual Property and competitively sensitive Business Information existing as of the Closing Date), Purchaser or its Affiliates that is not, in each case, already available to the public, provided that nothing herein or in the other
Transaction Documents shall be construed as precluding, prohibiting, restricting or otherwise limiting the ability of the Sellers, Sellers 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) make permitted disclosures under
Section 5.7; (iii) exercise or enforce any of its rights, or perform any obligations under this Agreement or the other Transaction Documents, including the Transition Services Agreement and the Intellectual Property License Agreement,
(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 in compliance with Section 5.33; (vi) use Confidential Information to the extent necessary to
perform Rejected Customer Contracts; or (vii) 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).

SECTION 5.12. Certain Payments or Instruments Received
from Third Parties. To the extent that, after the Closing Date, (a) the Purchaser, any Designated Purchaser or any Company receives any payment or instrument that is for the account of a Seller according to the terms of any Transaction
Document, the Purchaser shall, and shall cause the Designated Purchasers and the Companies 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, any of the Designated Purchasers or the Companies according to the terms of any Transaction Document, the Sellers shall, and shall cause the other Sellers to promptly deliver such amount or instrument to the Purchaser or the relevant
Designated Purchaser or Company, 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 best 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 Seller 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 Sublease cannot be entered into, without the Consent of the issuer thereof
or the other party thereto or the master landlord or any Third Party (including a Government Entity) (collectively, the Non-Assignable Contracts), this Agreement will not constitute an assignment thereof, or an attempted
assignment, nor shall any Sublease be entered



113



---

under any Non-Assignable Contract, unless any such Consent is obtained following Closing; provided, however, that the Sellers will use their reasonable best efforts to 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, including using
reasonable best efforts to enter into one or more mutually agreed Subcontract Agreements. As between the Sellers and the Purchaser (or the relevant Designated Purchaser), such Non-Assignable Contracts 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: (i) nothing in this Section 5.13 shall require any Seller to renew
any Non-Assignable Contract once it has expired, (ii) any efforts required of the Sellers pursuant to this paragraph shall (A) be subject to receipt of adequate compensation in respect of all direct incremental costs and expenses incurred
in respect of or related to such arrangement, (B) be strictly on an interim basis and in no event required to continue after the expiration of the term of the Transition Services Agreement, and (C) 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. The Purchaser or the Designated Purchaser, as applicable, shall reimburse the relevant Seller
for any direct incremental cost incurred 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. For the avoidance of doubt, 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 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 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, which
in all cases shall be no later than 12 months from the Closing Date unless otherwise agreed to by the Parties hereto. Any such Asset shall be deemed a Deferred Transfer Purchased Asset.



114



---

(d) If and to the extent that the allocation to Purchaser or any Designated Purchaser, and
Purchasers or any Designated Purchasers 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
or the fulfillment of any condition that cannot be fulfilled by Sellers prior to the Closing, then, to the extent permitted by applicable Law, including any Antitrust Laws and unless the parties hereto shall otherwise agree, the allocation to
Purchaser or any of its Subsidiaries of, and Purchasers or any such Designated Purchasers 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, and such
conditions are fulfilled. 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) 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) the Purchaser shall, or shall cause its applicable Subsidiary to, pay or reimburse
Seller for all amounts paid or incurred in connection with the retention of such Deferred Transfer Assumed Liability. 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(b), the sale of the applicable Deferred Transfer Purchased Asset 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 (A) be subject to receipt of adequate compensation in respect of all incremental costs and expenses incurred in respect of or related to such arrangement, (B) be strictly on an interim
basis and in no event required to continue after the expiration of the term under the Transition Services Agreement, (C) 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



115



---

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).

(h) Each of the Purchaser and the Sellers shall, and the Purchaser
shall cause any relevant Designated Purchaser and the Sellers shall cause any Subsidiary (other than the EMEA Sellers) to, use reasonable efforts and work cooperatively in good faith to facilitate the Purchasers negotiation with the
counter-party to any Inbound License Agreement or any Cross-License Agreement listed in Section 5.13(h) of the Sellers Disclosure Schedule that, in each case, is not a Seller Contract and is not assigned to the Purchaser or a Designated
Purchaser to obtain rights for the Purchaser or a Designated Purchaser to use the Intellectual Property that is licensed to the Sellers or a Subsidiary under such Inbound License Agreement or Cross-License Agreement, or, if that negotiation is
unsuccessful, the Sellers shall use reasonable efforts to provide the same interests, benefits, and rights under such Inbound License Agreement or such Cross-License Agreement, in each case, as reasonably necessary to effectively operate the
Business from and after Closing, including in the case of the Sellers requesting Consent to the grant of such rights from the relevant third party; 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 (including relinquishment of rights outside the Exclusive Purchaser Field, as defined in the Intellectual Property License Agreement) or to expend any amount or incur any
Liability or provide any other consideration in complying with its obligations under this Section 5.13(h).

SECTION 5.14.
Bundled Contracts; Selected Rejected Customer Contracts.

(a) 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 Contract that provides for the sale or provision of Products and/or Services and the sale or provision of other products and/or services of the Sellers or their Affiliates and is listed in Section 5.14 of the Sellers Disclosure Schedule
(a 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 and, unless otherwise agreed by the Purchaser, is on commercially reasonable terms that are consistent with contract terms that the
Purchaser generally offers to similarly situated customers, in which event such new Contract shall be deemed to be a Seller 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 with respect to any Bundled Contract. For the avoidance of doubt, the parties acknowledge that the failure to enter into such arrangements shall not entitle the
Purchaser to terminate this Agreement, not to complete the transactions contemplated hereby or reduce the Purchase Price payable hereunder. The Sellers shall use reasonable best efforts not to enter into any Bundled Contracts after the date hereof.
For the avoidance of doubt, under no circumstances shall the Purchaser be required to enter into any new customer contract (including, for the avoidance of doubt, a customer contract that relates to an SI/SP Contract) or, pursuant to



116



---

Section 5.14(b), any Subcontract with any customer that requires the Purchaser to deliver products and services of the Sellers other than the Products and the Services.

(b) Subject to applicable Law, for those Bundled Contracts that are not Post-Signing Customer Contracts and 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) if requested by the Purchaser, the Sellers shall use 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 Products and/or Services, and (ii) the Sellers and the Purchaser shall use 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 in so far as they relate to the Business, including by entering into Subcontract Agreements as follows: (A) if the
economic and other terms and conditions of the portion of any such Bundled Contract that relate to the Business (the Enterprise Portion) can be reasonably identified and the Enterprise Portion meets the Pre-Signing Inclusion
Criteria for Major Customer Contracts, the Purchaser or a Designated Purchaser shall enter into a Subcontract Agreement relating to such Enterprise Portion on the same terms as those set forth in the relevant Bundled Contract or (B) if the
Enterprise Portion of any such Bundled Contract cannot be reasonably identified or the Enterprise Portion does not meet the Pre-Signing Inclusion Criteria for Major Customer Contracts the Purchaser or a Designated Purchaser and the relevant Seller
shall use their reasonable best efforts to agree on commercially reasonable terms for the subcontract of such Enterprise Portion under a Subcontract Agreement and then enter into such Subcontract Agreement, it being understood that the terms of such
a Subcontract Agreement shall be considered commercially reasonable if and only if the terms of such Subcontract Agreement: (1) are at least as favorable to the Purchaser or the relevant Designated Purchaser as the terms generally offered by
the Purchaser or its Subsidiaries to customers that are similarly situated to the counterparty to the relevant Bundled Contract and (2) provide for material terms (including any terms addressed by the Pre-Signing Inclusion Criteria for Major
Customer Contracts) that are in the aggregate equivalent to, or better than, the material terms associated with the relevant Bundled Contract or the Enterprise Portion thereof; provided that (w) nothing in this Section 5.14 shall
require the Sellers to renew any Bundled Contract once it has expired, (x) the Sellers shall have the right, any time after the expiration of the Transition Services Agreement, to exercise any right to terminate any Bundled Contract and
(y) the Sellers shall be under no obligation with respect to the Enterprise 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, payment of Cure Costs for which the Sellers are responsible pursuant to
Section 2.1.7). Any Subcontract Agreement entered into pursuant to clause (A) or (B) above shall not require the Purchaser or the Designated Purchaser to perform under such Subcontract Agreement to the extent that the TSA Sellers are
in material breach of their obligation to perform services under the Transition Services Agreement and such breach frustrates the Purchasers ability to perform and (y) permit the Purchaser or the Designated Purchaser to terminate such
subcontract upon the earliest of (i) in the case of a Subcontract Agreement described in clause



117



---

(A) above, twelve (12) months from the Closing Date and in the case of a Subcontract Agreement described in clause (B) above, six (6) months from the Closing Date, (ii) the
expiration of the relevant Bundled Contract (without giving effect to any extension of the term thereof other than at the option of the counterparty thereto), (iii) the earliest date on which the relevant Seller has the right to terminate the
relevant Bundled Contract without penalty or (iv) the date on which the relevant Bundled Contract is terminated by the counterparty thereto. Notwithstanding the foregoing, the Purchaser shall be allowed to refuse to enter into a Subcontract
Agreement relating to a Bundled Contract if (i) the Purchaser offers to contract directly with the counterparty to such Bundled Contract on commercially reasonable terms that are consistent with contract terms that the Purchaser generally
offers to similarly situated customers or (ii) the Purchaser has an existing contract with the counterparty to such Bundled Contract and offers to provide the applicable Products and/or Services under such Bundled Contract through
Purchasers existing contract and pursuant to the terms thereof; provided that, in each of clauses (i) and (ii) of this sentence, the counterparty to the relevant Bundled Contract accepts the offer from the Purchaser and releases in
writing the relevant Seller from any obligation to perform and any other Liability under the Enterprise Portion of the relevant Bundled Contract.

(c) At least thirty (30) days prior to the Closing Date, the Sellers will deliver to the Purchaser a list of those Rejected Customer Contracts, if any, that the Sellers want the Purchaser to perform
on a subcontract basis after Closing (the Selected Rejected Customer Contracts); provided that, the Sellers shall not be allowed to include in such list of Selected Rejected Customer Contracts any
(i) (A) Rejected 365 SI/SP Contract, (B) Rejected Non-365 SI/SP Contract or (C) Rejected Customer Contract that is an Indirect Customer Contract, which, in each case, (1) if it is a 365 Contract, at the time of such
inclusion in the list can still be rejected by the relevant U.S. Debtor pursuant to section 365 of the U.S. Bankruptcy Code or (2) for any Contract, can be terminated by the relevant Seller at will without penalty, (ii) Customer Contract
that has expired pursuant to its terms, (iii) Post-Signing Customer Contract and (iv) any Bundled Contract. Subject to applicable Law, the Purchaser or a Designated Purchaser and the relevant Seller shall use their reasonable best efforts
to agree in good faith on commercially reasonable terms for each such Subcontract Agreement and shall then enter into such Subcontract Agreement, it being understood that the terms of any Subcontract Agreement shall (i) be considered
commercially reasonable if and only if the terms of such Subcontract Agreement: (A) are at least as favorable to the Purchaser or the relevant Designated Purchaser as the terms generally offered by the Purchaser or its Subsidiaries to customers
that are similarly situated to the counterparty to the relevant Selected Rejected Customer Contract and (B) provide for material terms (including any terms addressed by the Pre-Signing Inclusion Criteria for Major Customer Contracts) that are
in the aggregate equivalent to, or better than, the material terms associated with the relevant Selected Rejected Customer Contract and (ii) permit the Purchaser or the Designated Purchaser to terminate such subcontract upon the earliest of
(A) six (6) months from the Closing Date, (B) the expiration of the relevant Selected Rejected Customer Contract (without giving effect to any extension of the term thereof other than at the option of the counterparty thereto),
(C) the earliest date on which the relevant Seller has the right to terminate the relevant Selected Rejected Customer Contract without penalty or (D) the date on which the relevant Selected Rejected Customer Contract is terminated by the
counterparty thereto. Notwithstanding the above, any Subcontract Agreement entered into pursuant to clause (i)(A) or



118



---

(B) above shall not require the Purchaser or the Designated Purchaser to perform under such Subcontract Agreement to the extent that the TSA Sellers are in material breach of their obligation to
perform services under the Transition Services Agreement and such breach frustrates the Purchasers ability to perform and the Purchaser shall be allowed to refuse to enter into a Subcontract Agreement relating to a Selected Rejected Customer
Contract if (i) the Purchaser offers to contract directly with the counterparty to such Selected Rejected Customer Contract on commercially reasonable terms that are consistent with contract terms that the Purchaser generally offers to
similarly situated customers or (ii) the Purchaser has an existing contract with the counterparty to such Selected Rejected Customer Contract and offers to provide the applicable Products and/or Services under such Selected Rejected Customer
Contract through Purchasers existing contract and pursuant to the terms thereof; provided that, in each of clauses (i) and (ii) of this sentence, the relevant counterparty to the Selected Rejected Customer Contract accepts the offer
from the Purchaser and releases in writing the relevant Seller from any obligation to perform and any other Liability under the relevant Selected Rejected Customer Contract.

SECTION 5.15. Post-Closing Assistance for Litigation.

(a) After the Closing, the Purchaser shall, upon the request of the Sellers, and at no cost to the Sellers (other than reimbursement of out of pocket expenses), make the Transferred Employees 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 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 Business prior to the Closing Date; provided, however, that the obligations of the Purchasers or their Affiliates hereunder shall only extend to the employees of such Purchasers or Purchasers 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) After the Closing, the Sellers and their Affiliates shall, upon the request of the Purchaser, and at no cost to the Purchaser or its
Affiliates (other than reimbursement of 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 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 Sellers Affiliates that have been terminated prior to such
date.

SECTION 5.16. Tangible Asset Removal.



119



---

(a) The Purchaser shall, and shall cause the relevant Designated Purchasers to, within
thirty (30) days after the Closing Date, relocate all tangible Assets and Purchasers activities from all premises owned or leased by the Sellers or their Affiliates after the Closing (other than those premises to be occupied by the
Purchaser or any Designated Purchasers after the Closing Date pursuant to the provisions of the Real Estate Agreements, the Assumed and Assigned Contracts, and the Company Leases) with Sellers cooperation; provided, however, that,
subject to receipt of landlord Consent where required (it being agreed that 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
Purchasers obligation to use commercially reasonable efforts to vacate all such premises as soon as reasonably practicable regardless of the length of the Applicable Transitional Occupancy Period, the Purchaser shall be permitted to remain in
occupancy, pursuant to the terms of customary forms of license agreements reasonably acceptable to the Purchaser and Sellers, at those premises identified in Section 5.16(a) of the Sellers Disclosure Schedule (to the extent such premises are
not to be occupied by the Purchaser or any Designated Purchasers after the Closing Date pursuant to the provisions of the Real Estate Agreements, the Assumed and Assigned Contracts, and the Company Leases), for, in each instance, the Applicable
Transitional Occupancy Period, subject to the following conditions:

(i) in all instances other than the
properties identified in Section 5.16(a) of the Sellers Disclosure Schedule, 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 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) the expiration of the Applicable Transitional Occupancy Period, 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 the Applicable Latest
Termination Notification Date.

(ii) The Purchaser or the relevant Designated Purchasers shall only be entitled
to remain in occupancy of the premises identified in Section 5.16(a) of the Sellers Disclosure Schedule during the Applicable Transitional Occupancy Period so long as the Purchaser or the relevant Designated Purchasers (1) in the case of
any real property identified in Section 5.16(a) of the Sellers Disclosure Schedule which is leased by a Seller as a tenant, compensates Sellers for Sellers actual, out of pocket rent and other occupancy costs with respect to either, as
indicated in Section 5.16(a) of the Sellers Disclosure Schedule, (A) the space actually being occupied by the Purchaser or such Designated Purchaser or (B) the entire premises subject to the applicable real estate lease, and in either
case indemnifies the Seller for any liability or damages resulting from the Purchasers or such Designated Purchasers continued occupancy from the Closing Date through the



120



---

date upon which the Purchaser or such Designated Purchaser actually surrenders such property in accordance with the requirements of the license agreement referenced above, and (2) in the
case of any real property identified in Section 5.16 of the Sellers Disclosure Schedule which is owned by a Seller, compensates Sellers for the Purchasers or such Designated Purchasers occupancy of such property by paying fair
market rental for such portion of the property that the Purchaser or such Designated Purchaser is actually occupying and indemnifying Seller for any liability or damages resulting from the Purchasers occupancy.

(iii) In any circumstance where a landlords Consent is required to permit the Purchasers continued occupancy of
premises identified in Section 5.16(a) of the Sellers Disclosure Schedule during the Applicable Transitional Occupancy Period and Sellers have been unable, despite using commercially reasonable efforts, to procure such Consent prior to the
Closing Date, (A) the Purchaser shall not have the right to continue in occupancy of such premises and, notwithstanding any provision herein to the contrary, the Applicable Transitional Occupancy Period shall not extend beyond the Closing Date
and (B) the Sellers will cooperate with the Purchaser, at the Purchasers sole cost and expense, to provide access to the applicable premises for the purpose of expediting the Purchasers removal of assets therefrom; provided
that the Purchaser (or the relevant Designated Purchaser) shall perform all obligations and covenants set forth in this Section 5.16 with respect to such premises for so long as its property remains in such premises and provided further
that neither any Seller nor any Affiliate of any Seller shall have any liability to the Purchaser (or a Designated Purchaser) for the refusal by any landlord to grant a consent to any transitional occupancy by the Purchaser (or a Designated
Purchaser). Notwithstanding the foregoing, nothing in this Section 5.16 shall require any Seller to renew or extend the term of any lease once it has by its terms expired. The Purchaser or the Designated Purchaser, as applicable, shall hold
each Seller harmless from and against all Liabilities, incurred or asserted, as a result of any actions taken pursuant to this Section 5.16.

(iv) 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 neither an Assumed and Subleased
Real Estate Lease nor a Non-365 Subleased Real Estate Lease and at which Owned Equipment is located and which is not identified in Section 5.16(a) of the Sellers Disclosure Schedule, 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 the Applicable Latest Termination Notification Date) 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 Sellers sole cost until delivery to the Purchaser or a Designated Purchaser at Closing (it being understood that Sellers shall not be obligated to remove trade fixtures or fixtures, furniture, furnishings or
fittings from any such real property



121



---

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.

(v) The Purchaser or the relevant Designated Purchaser shall surrender any such premises in substantially the same condition in which the Purchaser or such Designated Purchaser received it (with the
Assets removed and broom clean).

(b) The Sellers shall, within thirty (30) days after the Closing Date, relocate all the
Excluded Assets and Sellers activities from all owned real property or other leased or subleased real property covered by this Agreement with the Purchasers cooperation; provided, however, that, subject to receipt of landlord
Consent where required (it being agreed that the Purchaser shall only be obligated to use commercially reasonable efforts, without incurring any third-party costs, to obtain any such required Consents), pursuant to the terms of license agreements
referred to in Section 5.16(a) above, the Sellers shall have up to six (6) months after the date of the Closing to relocate all the Excluded Assets and Sellers activities from the premises listed in Section 5.16(b) of the
Sellers Disclosure Schedule, subject to the following conditions:

(i) in all instances other than in the case
of the premises shown on Section 5.16(b) of the Sellers Disclosure Schedule, the Purchasers obligation to make any space available to the Sellers or any other party on the date of or following Closing shall be subject to the
Purchasers right to implement its global real estate strategy, as such strategy develops over time, and in connection therewith to dispose of or retain real estate assets as the Purchaser deems appropriate in its sole discretion and the
Purchaser shall have no liability to the Sellers or any other party resulting from the implementation of the Sellers real estate strategy as contemplated hereby; provided that if the Purchaser exercises its right to dispose of real
estate assets prior to the earlier of (A) the date on which Sellers vacate the related property at their own election and (B) the six (6) month anniversary of the date of this Agreement, in the case of any real property identified in
Section 5.16(b) of the Sellers Disclosure Schedule, or thirty (30) days after the Closing Date in the case of any other real property, the Purchaser shall give the Sellers reasonable notice, not less than thirty (30) days, of such
disposal and a reasonable opportunity to remove the Excluded Assets located thereon;

(ii) the Sellers shall
only be entitled to remain in occupancy of the premises identified in Section 5.16(b) of the Sellers Disclosure Schedule for



122



---

periods of up to six (6) months from the date of Closing so long as the Sellers (1) in the case of any real property identified in Section 5.16(b) of the Sellers Disclosure
Schedule which is leased by the Purchaser or a Designated Purchaser as a tenant, compensates the Purchaser or such Designated Purchaser for the Purchasers or such Designated Purchasers actual, out of pocket rent and other occupancy costs
with respect to the space actually being occupied by the Seller and indemnifies the Purchaser or such Designated Purchaser for any liability or damages resulting from the Sellers continued occupancy from the Closing Date through the date upon
which Seller actually surrenders such property in accordance with the requirements of the license agreement referenced above, and (2) in the case of any real property identified in Section 5.16(b) of the Sellers Disclosure Schedule which
is owned by the Purchaser or a Designated Purchaser, compensates the Purchaser or such Designated Purchaser for the Sellers occupancy of such property by paying fair market rental for such portion of the property that Seller is actually
occupying and indemnifying the Purchaser or such Designated Purchaser for any liability or damages resulting from the Sellers occupancy;

(iii) in any circumstance where a landlords Consent is required to permit a Sellers occupancy of premises identified in Section 5.16(b) of the Sellers Disclosure Schedule for up to six
(6) months following the Closing Date and the Purchaser has been unable, despite using commercially reasonable efforts, to procure such Consent prior to the Closing Date, (A) the relevant Seller shall not have the right to continue in
occupancy of such premises beyond the Closing Date and (B) the Purchaser will cooperate with the Sellers, at Sellers sole cost and expense, to provide access to the applicable premises for the purpose of expediting Sellers removal
of assets therefrom; provided that the relevant Seller shall perform all obligations and covenants set forth in this Section 5.16(b) with respect to such premises for so long as its property remains in such premises and provided
further that neither the Purchaser nor any Designated Purchaser nor any Affiliate of any either shall have any liability to any Seller for the refusal by any landlord to grant a consent to any transitional occupancy by a Seller. Notwithstanding the
foregoing, nothing in this Section 5.16 shall require the Purchaser or a Designated Purchaser to renew or extend the term of any lease once it has by its terms expired. The relevant Seller shall hold the Purchaser or a Designated Purchaser
harmless from and against all Liabilities, incurred or asserted, as a result of any actions taken pursuant to this Section 5.16; and

(iv) the Sellers shall surrender any such premises in the substantially the same condition in which the Sellers received it (with the Excluded Assets removed and broom clean).

(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.



123



---

(d) From the date hereof until the Closing Date, in addition to providing the reasonable
notice specified above of Sellers intent to reject or otherwise terminate any 365 Real Estate Leases, any Non-365 Real Estate Leases and any other leases where Assets are located, Sellers shall keep Purchaser reasonably informed of any
activities at any of the premises subject to a Real Estate Lease that may impact the transition arrangements. Sellers and Purchaser shall cooperate to plan reasonable transition arrangements at the real property listed in Sections 5.16(a) and
5.16(b) of the Sellers Disclosure Schedule as well as other real property subject to this Agreement, in accordance with the principles set forth in this Section 5.16.

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 or the Companies (except the Transferred Overhead and Shared Services) shall cease and (ii) the
Sellers or their Affiliates shall have no further obligation to provide any Overhead and Shared Services to the Companies and/or the Business.

SECTION 5.18. [Reserved].

SECTION 5.19. Cancellation of Intercompany
Accounts. The Sellers shall procure that all payables and/or receivables between the Sellers or any of their Affiliates (other than the Companies), on the one hand, and the Companies, on the other hand, be cancelled without payment prior to or
as of the Closing Date.

SECTION 5.20. Directors and Officers Release, Indemnification and Insurance.

(a) The Purchaser shall cause the Companies to irrevocably release and discharge, effective as of the Closing Date, the
directors and officers of the Companies holding office as of the Closing Date and any former director or officer of the Companies from and against any and all past, existing or future, claims, demands, obligations and Liabilities, whether known or
unknown, suspected or unsuspected, at law or in equity, arising from or related to any act or omission by any of those individuals in their capacity of directors or officers of the Companies prior to the Closing Date; provided, however, nothing
herein shall release or discharge the directors and officers of the Companies of any criminal acts, fraud or other intentional malfeasance contrary to the interests of the Companies.

(b) The Purchaser further agrees that all rights to exculpation, indemnification and advancement of expenses now existing in favor of the
current or former directors, officers or employees, as the case may be, of the Companies as provided in their respective certificates of incorporation or by-laws or other similar constituent documents or in the agreements listed on Section 5.20
of the Sellers Disclosure Schedule shall continue in full force and effect after the Closing. For a period of 6 years from the Closing Date, the Purchaser shall cause the Companies to (i) maintain in effect the exculpation, indemnification and
advancement of expenses provisions of any Companys certificates of incorporation and by-laws or similar constituent documents as in effect on the date hereof or in any indemnification agreements listed on Section 5.20 of the Sellers
Disclosure Schedule, and (ii) not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals



124



---

who at the Closing Date were current or former directors, officers or employees of the Companies; provided, however, that all rights to indemnification in respect of any actual or
threatened Action pending or asserted or any claim made within such period shall continue until the disposition of such Action or resolution of such claim. From and after the Closing Date, the Purchaser shall cause the Companies to honor, in
accordance with their respective terms, each of the covenants contained in this Section 5.20 without limit as to time.

(c) From and after the Closing, the Purchaser shall, and shall cause the Companies to, to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current
and former director or officer of the Companies (each, together with such Persons heirs, executors or administrators, an Indemnified Person) against any costs or expenses (including advancing reasonable attorneys fees
and expenses in advance of the final disposition of any claim or Action to each Indemnified Person to the fullest extent permitted by Law), judgments, fines, losses, claims, damages, Liabilities and amounts paid in settlement in connection with any
Action, arising out of, relating to or in connection with any such Persons service as a director or officer of the Companies or services performed in connection with such Persons serving as an officer or director or other fiduciary in
any entity if such service was at the request or for the benefit of the Companies, in each case, at or prior to the Closing Date (collectively, the Indemnified Expenses); provided, however, that the Purchaser and the
Companies shall not be liable for any settlement effected without their prior written consent and the Purchaser and the Companies shall not be obligated to pay the fees and expenses of more than one counsel (selected by a plurality of the applicable
Indemnified Persons and reasonably satisfactory to the Purchaser or the Companies, as applicable) for all Indemnified Persons in any jurisdiction with respect to any single such claim or Action, unless the use of one counsel for such Indemnified
Persons would present such counsel with a conflict of interest that would make such joint representation inappropriate. In the event of any such Action, the Purchaser shall, and shall cause the Companies to, reasonably cooperate with the Indemnified
Person in the defense of any such Action. Notwithstanding the foregoing, nothing herein shall require the Purchaser to, or cause the Companies to, reasonably cooperate with or indemnify and hold harmless any current or former director or officer of
a Company against any Indemnified Expenses arising out of, relating to or in connection with any criminal acts, fraud or other intentional malfeasance contrary to the interests of such Company.

(d) The Purchaser shall, and shall cause the Companies to, obtain, effective as of the Closing Date, tail insurance policies
with a claims period of at least six years from the Closing Date with respect to directors and officers liability insurance of the type and with an amount of coverage as are substantially similar to those of the directors and
officers liability insurance maintained as of the date hereof by the Sellers and the Companies (the Current Policies), and with such other terms as are no less favorable than those of the Current Policies; provided
that, in satisfying such obligation, the Companies shall not be obligated to pay aggregate premiums in excess of 225% of the aggregate per annum amount that the Sellers or the Companies paid for such coverage of such directors and
officers liability under the Current Policies in the last full year prior to the date hereof, it being understood and agreed that the Companies shall nevertheless be obligated to provide the maximum coverage as may be obtained for such amount.



125



---

(e) The Purchaser shall cause the Companies to pay all reasonable expenses, including
reasonable attorneys fees, that may be incurred by any Indemnified Person in enforcing the indemnity and other obligations provided in Section 5.20.

(f) The rights of each Indemnified Person hereunder shall be in addition to, and not in limitation of, any other rights such Indemnified Person may have under the certificates of incorporation or by-laws
or other constituent documents of the Companies, any other indemnification arrangement, the Delaware General Corporation Law or otherwise. The provisions of this Section 5.20 expressly are intended to benefit, and are enforceable by, each of
the Indemnified Persons.

(g) In the event the Purchaser or any Company or any of their successors or assigns
(i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person,
then, and in either such case, proper provision shall be made so that the successors and assigns of the Purchaser or the Companies shall assume the obligations set forth in this Section 5.20.

SECTION 5.21. 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 and the Companies (collectively with the Business and the Companies, the Covered Assets and Persons) under all current or previous insurance policies of
the Sellers and their Affiliates (other than the Companies), 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 (other than the Companies) 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. Except to the extent provided in Section 2.1.1(p) or Section 5.21(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 or the Companies.

(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



126



---

their respective Affiliates), as applicable, promptly upon a written request therefore. 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 Purchaser shall be
exclusively responsible for acquiring from such insurance company or Third Party, at the Purchasers sole cost and expense, the rights necessary to permit them to obtain access to and utilization of such claims data or information. 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 property insurance in respect of the Included Real Estate and the Owned Equipment (including buildings, equipment, leasehold
improvements and business interruption) and make and diligently pursue any applicable insurance claims related to damage or destruction to any Owned Equipment wherever located, or any damage or destruction to improvements or leasehold improvements
owned by, or the responsibility of, the Sellers and located at or on any Included Real Estate, it being acknowledged that the insurance provisions in the relevant Real Estate Leases will apply where damage or destruction has occurred to the extent
applicable. Notwithstanding anything in this Agreement to the contrary:

(i) if and to the extent that any
Owned Equipment, 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 Owned Equipment (excluding any insurance proceeds related to business interruption insurance) that have not been applied to repair, replacement or restoration, as applicable, and assign any such
claim and the rights to receive the proceeds of any such claim that has not yet been finally adjusted;

(ii) if
and to the extent that the Owned Real Estate (to the extent the Purchaser exercises its election under Section 2.1.1 to purchase the Owned Real Estate) 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 Owned Real Estate (excluding any proceeds related to business interruption
insurance) that have not been applied to repair, replacement or restoration, as applicable, and assign any such claim and the rights to receive the proceeds of any such claim that has not yet been finally adjusted;

(iii) if and to the extent that any leasehold improvements at any property that is subject to a Designated 365 Real Estate
Lease, Designated Non-365 Real Estate Lease, or Company Lease are destroyed or damaged prior to Closing and are not replaced or repaired or restored to their condition prior to such damage or destruction, then at Closing, with respect to any such
leasehold improvements (excluding any proceeds related to business interruption insurance), the Sellers shall pay to the Purchaser the amount of any net insurance proceeds received in respect of such leasehold improvements that have not been



127



---

applied to repair, replacement or restoration, as applicable, and assign any such claim and the rights to receive the proceeds of any such claim that has not yet been finally adjusted;

(iv) if and to the extent that any improvements or leasehold improvements at any property that is subject to a
Sublease are destroyed or damaged prior to Closing, to the extent of the receipt of insurance proceeds (excluding any proceeds related to business interruption insurance) and subject to the terms of the overlease, the Sellers shall be responsible to
the extent required under the terms of the Sublease (as if the Sublease were in effect prior to Closing and as if the sublandlord were obligated to restore such improvements and leasehold improvements under the Sublease, unless and to the extent the
prime landlord is expressly obligated to restore such improvements under the terms of the overlease), to restore the applicable improvements and leasehold improvements to the condition prior to such damage or destruction. To the extent that any
property subject to a Sublease is destroyed or damaged after Closing, the applicable terms of the Sublease shall apply; and

(v) if and to the extent that any Direct Lease Real Estate is destroyed or damaged prior to Closing, to the extent of the receipt of insurance proceeds (excluding any proceeds related to business
interruption insurance), the Sellers shall be responsible to the extent required under the terms of the Direct Lease (as if the Direct Lease were in effect prior to Closing and as if the landlord were required to restore tenant improvements in the
same manner as other improvements) to restore the applicable improvements and leasehold improvements to the condition prior to such damage or destruction. To the extent that any Direct Lease Real Estate is destroyed or damaged after Closing, the
applicable terms of the Direct Lease shall apply.

SECTION 5.22. Sellers Deposits, Guarantees and Other Credit Support of
the Business. Following the Closing, the Purchaser shall, or shall cause a Designated Purchaser to:

(a) procure the
return and/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:

(i) any lease security deposits given by the Sellers under those real estate leases listed in Section 5.22(a)(i) of the
Sellers Disclosure Schedule that are Assigned Contracts that have not been set off or otherwise applied by the holders thereof (the Security Deposits); and

(ii) 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 (other than the Companies) or any Third Party on behalf (and with a counter guarantee of) the Sellers in favor of Third Parties, securing Liabilities of the Business under the
Assigned Contracts or Liabilities of the Companies; provided that the obligations of Purchaser or any Designated Purchaser under this Section 5.22(a)(ii) shall be limited, in the case of



128



---

any Real Estate Lease, to guaranties, credit support, letters of credit, performance bonds and sureties identified in Section 5.22(a)(ii) of the Sellers Disclosure Schedule;

(b) if the Security Deposits are not released or returned to the relevant Seller within thirty (30) days from Closing, pay to the
relevant Seller an amount equal to such outstanding Security Deposits (in which case, effective upon such payment, the relevant Seller hereby assigns to the Purchaser any right or credit against the relevant lessor relating to such Security
Deposit); and

(c) hold harmless the Sellers and their Affiliates from and against any Loss resulting from, or relating to,
any obligation set forth in clauses (a) and (b) of this Section 5.22.

SECTION 5.23. Use of Sellers
Trademarks. Except as expressly provided in the Trademark License Agreement, as of the Closing Date, neither Purchaser nor the Companies shall have the right to use, and the Purchaser shall cause the Companies to cease and desist from all use
of, the name Nortel or any Trademarks owned by the Sellers or any of their Affiliates or any other mark employing the word Nortel or any confusingly similar Trademarks to any of the foregoing (collectively, the
Sellers Trademarks) and the Purchaser shall cause the Companies to adopt new Trademarks related thereto which are not confusingly similar to the Sellers Trademarks and logos.

SECTION 5.24. Maintenance of Books and Records.

(a) After the Closing, the Purchaser shall, and shall cause the Designated Purchasers and the Companies to, 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 Business possessed or to be possessed by such Person. After the Closing Date and 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 Sellers or their representatives, the Purchaser shall, and/or shall cause the Person holding such records to, (a) provide to the Sellers or their
representatives reasonable access to such records during normal business hours and (b) permit the Sellers or their representatives to make copies of such records, in each case at no cost to the Sellers or their representatives (other than for
reasonable out-of-pocket expenses). In addition, in the event that the financial statements of the Business or the Companies are audited for any period prior to the Closing Date, upon execution of a customary access letter if required, the Sellers
and their representatives (including their outside accountants) shall be granted access to all relevant work papers, schedules, memoranda and other documents prepared by the Companies or their representatives (including outside accountants) in
connection with the Sellers completing the audit of their accounts for the 2009 fiscal year; provided, however, that nothing herein shall require the Purchaser to disclose any information to the Sellers 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 Purchaser shall cooperate in any reasonable efforts and requests that would enable otherwise required
disclosure to the Sellers to occur without so jeopardizing privilege or contravening such Law, duty or agreement) or require the Purchaser to disclose its Tax records. Such records may be sought under this Section 5.24 for any reasonable
purpose, including to the extent reasonably



129



---

required in connection with accounting, litigation, federal securities 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 or audited financial statements covering any pre-Closing period.

(b) After the Closing, 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 Business possessed or to be possessed by such Person. After the Closing Date and 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,
(a) provide to the Purchaser, any Designated Purchaser or their respective representatives reasonable access to such records during normal business hours and (b) permit the Purchaser, any Designated Purchaser or their respective
representatives to make copies of such records, in each case at no cost to the Purchaser, such Designated Purchaser or their respective representatives (other than for reasonable out-of-pocket expenses); provided, however, that nothing herein
shall require any Seller 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 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 require the Sellers to disclose their Tax records. Such records may be sought under this Section 5.24(b) for any reasonable purpose, including to the
extent reasonably required in connection with accounting, litigation, federal securities 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, (i) 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 desires 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 (ii) 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 or audited financial statements covering any
pre-Closing period.

SECTION 5.25. Right to Exclude.

(a) At any time from the execution of this Agreement until the end of the Contract Review Period, the Purchaser may elect, by written notice
to the Main Sellers, but without any effect on the Purchase Price or the Purchasers obligation to offer employment to at least the numbers of Employees set out in Section 7.1.1 of the Sellers Disclosure Schedule, to designate as Excluded
Assets all of the assets, interests and rights of any Excludable Other Seller if (i) such Excludable Other Seller is listed on Section 5.25(a) of the Sellers Disclosure Schedule, or (ii) it is the case that, absent such election, by
consummating the transactions contemplated hereby, the Purchaser or a Designated Purchaser would succeed to an Undisclosed Material Liability of such Excludable Other Seller or an Undisclosed Material Liability of such Excludable Other Seller would
be transferred to or assumed by the Purchaser or a Designated Purchaser (any such Excludable Other Seller so designated by the Purchaser, an Excluded Other Seller and, together with any Excluded EMEA Seller, the Excluded
Sellers), whereupon such assets, interests and rights shall be Excluded Assets and any Liabilities to the extent arising from or related to such assets, interests or rights shall be Excluded Liabilities, and such Excluded Other Seller
shall not be a Party to this Agreement, shall not be an Other Seller, and shall have no rights or obligations hereunder, provided that (x) each Excluded Other Seller shall remain bound by the provisions of Article X, (y) the Data
Inventory Floor, the Voice Inventory Floor, the Spares and Services Inventory Floor, the Inventory Value, the Sellers Inventory Schedule and the revenue assumptions presented in the Sellers Forecast set forth in Section 1.1(d)(ii) of the
Sellers Disclosure Schedule shall be adjusted after the end of the Contract Review Period to reflect the exclusion of the relevant revenues and inventory of the Excluded Sellers, and (z) and each Excluded Other Seller shall retain the right to
designate (A) any Customer Contracts to which it is a party that was entered into in the Ordinary Course and meets the requirements of the first sentence of Section 5.14(c) (other than clause (iii) thereof) as a Selected Rejected
Customer Contract entitled to the benefits of Section 5.14(c) and (B) the Enterprise Portion of each Bundled Contract to which it is a party as an Enterprise Portion entitled to the benefits of Section 5.14(b)(B). In addition to the
foregoing, following such election of an Excluded Other Seller by the Purchaser, no Sublease and no license or other arrangement pursuant to Section 5.16(a) shall be required to be entered into with respect to any premises related to such
Excluded Other Sellers operations prior to the date of the Purchasers election. For the avoidance of doubt, the designation of assets, interests or rights in any country as Excluded Assets shall not in any way prevent the Purchaser or
any of its Affiliates from engaging in the Business (defined as if such assets, interests or rights were not Excluded Assets) in such country either before or after the Closing. Any Customer Contract to which any Seller (or any of its Subsidiaries)
that is designated as an Excluded Asset is party will be deemed to be a Rejected Customer Contract. If a TSA Seller becomes an Excluded Other Seller pursuant to this Section 5.25(a), such entity shall not be required to be a party to the
Transition Services Agreement. For the avoidance of doubt, the failure of any TSA Seller to become party to the Transition Services Agreement shall not in any way diminish the obligations of the remaining TSA Sellers to provide, or to cause one or
more of the Providers (as defined in the Transition Services Agreement) to provide, all Services (as defined therein). Notwithstanding anything herein to the contrary, the Parties agree that neither the Included Services nor the Extra Services shall
include any service currently provided by an Excluded Seller unless such service can



131



---

reasonably be provided by the TSA Sellers without materially changing or burdening the operations of the TSA Sellers.

(b) The Main Sellers agree that, as of the Closing, (i) neither any Seller nor any Sellers Affiliate will be a party to any
Contract with any Excluded Seller that will restrict the Purchaser or a Designated Purchaser, in any material respect, from engaging after the Closing in any business activity relating to the Business in the country where such Excluded Seller is
located or organized; and (ii) the Sellers and their Affiliates will cease to supply Products or Services or provide other assistance to an Excluded Seller with respect to the Business (except to the extent required in order to allow such
Excluded Seller to continue to perform any obligations under (x) a contract with one of its customers existing as of the date hereof, or (y) a contract with one of its customers entered into after the date hereof but before Closing that
complies with the Post-Signing Inclusion Criteria entered into in the Ordinary Course, in each case which such Excluded Seller is required by such contract to perform until the earliest of (A) the expiration of such contract (without giving
effect to any extension of the term thereof other than at the option of the counterparty thereto), (B) the earliest date on which such Excluded Seller has the right to terminate such contract without penalty or (C) the date on which such
contract is terminated by the counterparty thereto; provided that the Purchaser and its Affiliates shall be under no obligation to make Products or Services (or any other products or services) available to the Sellers or their Affiliates or provide
other assistance in connection therewith) and the Purchaser and its Affiliates will have no obligation to supply Products or Services (or any other products or services) or provide other assistance to the Excluded Sellers; provided that,
notwithstanding clauses (i) and (ii) above, the Purchaser or a Designated Purchaser will, if requested to do so, perform any Subcontracts that it enters into pursuant to Section 5.14(c) or Clause 10.35 of the EMEA Asset Sale Agreement
at the request of an Excluded Seller and the Sellers may be a conduit through which the Purchaser supplies Products or Services to an Excluded Seller.

SECTION 5.26. Certain Ancillary Agreements.

(a) The Primary Parties and,
to the extent applicable, the relevant EMEA Sellers, shall use their reasonable best efforts to:

(i) negotiate
in good faith with the relevant contract manufacturers to finalize the terms of the Contract Manufacturing Inventory Agreements based on the term sheet attached hereto as Exhibit E;

(ii) negotiate in good faith with the LGN Joint Venture the LGN/Korea Distribution Agreement and the LGN/Korea Supply

(iii) negotiate in good faith with Uni-Nortel the Uni-Nortel Distribution Agreement, subject to the Sellers production of sufficient information on the relevant entities and documents.

(b) The Parties and the EMEA Sellers acknowledge that, as of the date hereof, the Business entertains several bilateral relationships
with other businesses, business segments or



132



---

divisions of certain Sellers for the supply and/or development of products and services (including certain Products and Services). To the extent such relationships are required to be in place in
order to fulfill customer commitments existing as of the Closing Date and which will continue thereafter (for the duration of any individual customer contract including frame contracts), the Primary Parties and the relevant EMEA Sellers shall use
their reasonable best efforts to negotiate, or to cause to be negotiated, in good faith commercially reasonable terms in order to address the interdependencies among businesses set forth in Exhibit L, including through a potential Mutual
Development Agreement, Purchaser Supply Agreement, Seller Supply Agreement or other appropriate commercial arrangements, and taking into account options available to the Primary Parties. The Primary Parties shall also use their reasonable best
efforts to negotiate in good faith Subcontract Agreements.

(c) On or before the Closing, the relevant Parties shall enter
into the Transition Services Agreement, the Intellectual Property License Agreement and the Trademark License Agreement, each in the form attached hereto.

Sellers covenant that they shall not commence any action under sections 544 through 551, 553 and 558 of the U.S. Bankruptcy Code against any customer, contract party or vendor of the Business.

SECTION 5.28. Subleases.

(a) For each Assumed and Subleased Real Estate Lease designated to be subleased pursuant to Section 2.1.5(b) or Non-365 Subleased Real Estate Lease designated to be subleased pursuant to
Section 2.1.6(b), the relevant Seller, as sublandlord, and Purchaser or a Designated Purchaser, as subtenant, will enter into a sublease in the form attached hereto as Exhibit N (each such sublease a Sublease) at
Closing with a term to expire one Business Day prior to the scheduled expiration date of the applicable Assumed and Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease (subject to the provisions of Section 5.31) with respect to
the portion of the applicable property to be used by the Purchaser or a Designated Purchaser for the Business.

(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 Purchaser or a Designated Purchaser (which shall, other than in the case of
any Sublease relating to Lease A or Replacement Lease A (which shall be determined in accordance with Exhibit 5.28(g)) and any Sublease relating to Lease B (which shall be determined in accordance with Exhibit 2.1.5(b)(v)), be based upon the
contemplated use of the demised premises and employee headcount reasonably agreed between Purchaser and Sellers on or prior to the Closing Date and 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 provide relevant information (subject to confidentiality limitations) on the subleased premises to the other provided that it is
understood



133



---

and agreed that all costs of such segregation and demising will be the sole responsibility of Purchaser and that Purchasers plans and specifications therefor will be subject to
Sellers reasonable approval.

(c) From and after the date hereof and subject in all cases to Section 5.28(d),
Purchaser shall be permitted to contact and have reasonable access to any landlord under the Assumed and Subleased Real Estate Leases or Non-365 Subleased Real Estate Leases for the purpose of (x) negotiating a direct lease between such
landlord and Purchaser or Designated Purchaser for all or a portion of the space covered or reasonably anticipated to be covered by the relevant Sublease, (y) recognition and non-disturbance protections for the benefit of Purchaser, and/or
(z) leasing other space in the building to which the Assumed and Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease relates (it being agreed that the leasing or subleasing of such other space shall not relieve Purchaser or a
Designated Purchaser of its obligations in respect of the relevant Sublease) and for no other purpose. Seller shall cooperate with Purchaser or Designated Purchaser and use commercially reasonable efforts, without incurring any third-party costs, to
assist Purchaser or Designated Purchaser in connection with such negotiations.

(d) Purchasers rights set forth in
Section 5.28(c) shall be subject to applicable Law and the following conditions:

(i) Seller and Purchaser
or Designated Purchaser shall have reasonably agreed on a mutually acceptable strategy for negotiations with each landlord (including, without limitation, the ability of the Purchaser or a Designated Purchaser to enter into a direct lease for all or
less than all of the space covered or reasonably anticipated to be covered by the relevant Sublease in lieu of a Sublease) and the Main Sellers shall be afforded the right to participate in all such communications with the landlord to the extent
that they wish to do so,

(ii) neither any Seller nor Purchaser nor Designated Purchaser shall have any
obligation to agree to any increase in any of its obligations under the applicable Assumed and Subleased Real Estate Lease, Non-365 Subleased Real Estate Lease or Sublease in connection with such discussions with the landlords,

(iii) such negotiations shall be immediately terminated if they are having an adverse impact on the landlord-tenant
relationship between the Sellers and such landlord, as determined by the Sellers in their reasonable discretion,

(iv) the Sellers shall have no obligations under or with respect to such direct lease negotiated by Purchaser or any Designated Purchaser, and

(v) neither Purchaser nor any Designated Purchaser shall be permitted to enter into a direct lease without obtaining NNIs prior written consent, which consent may be granted or withheld in the
Sellers sole discretion, unless:



134



---

(A) there is no modification to the terms of the related Assumed and
Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease that is adverse to the Sellers in connection with the entry into such direct lease,

(B) the Sellers shall not be obligated to pay any fees, penalties or other charges in connection with the entry into the direct lease by the Purchasers or the Designated Purchaser,

(C) Sellers are fully and finally released from all obligations and liability to such landlord and any other parties with
respect to the space subject to the direct lease, and

(D) either (x) all, but not less than all, of the
space covered or reasonably anticipated to be covered by the relevant Sublease is subject to such direct lease or (y) if such proposed direct lease covers less than all of the space covered or reasonably expected to be covered by the relevant
Sublease then (A) the remainder of such space (taking into account the relevant loss factors and all common area cost allocation) is expressly removed from the demised premises for all purposes covered by the relevant Assumed and Subleased Real
Estate Lease or Non-365 Subleased Real Estate Lease and the rent and additional rent obligations of Seller is reduced accordingly and (B) the demised premises which thereafter remain subject to a Sellers Assumed and Subleased Real Estate
Lease or Non-365 Subleased Real Estate Lease is not divided into two or more non-contiguous portions and is not less marketable than it was prior to Purchasers or Designated Purchasers entry into such direct lease.

(e) After the Closing, the subtenant under each Sublease shall also be permitted to have contact with the landlord under the related Assumed
and Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease on routine facilities maintenance matters, and the applicable sublandlord will reasonably cooperate with such subtenant, at Purchasers expense, to enforce the obligations
of such landlord under the applicable Assumed and Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease.

(f)
With respect to the Sublease of property located at Belleville, Ontario, the Sellers agree that they will not exercise any options to extend the applicable Non-365 Subleased Real Estate Lease related thereto and the Purchaser or a Designated
Purchaser will in its sole discretion be permitted to negotiate a direct lease with the landlord with respect to the time after the expiration of the term of the applicable Non-365 Subleased Real Estate Lease and Sellers shall have no obligations
under or with respect to such direct lease.

(g) Notwithstanding any provision of this Agreement to the contrary, Purchaser
(on behalf of itself and any Designated Purchaser) and Sellers agree to be bound by and comply with the terms set forth in Exhibit 5.28(g) with respect to the 365 Real Estate Lease identified as Lease A in
Section 2.1.5(b)(iii) of the Sellers Disclosure Schedule and the Replacement Lease A identified in such Exhibit 5.28(g).

SECTION 5.29. Competing Transaction. From the date of this Agreement until the entry
of the U.S. Bidding Procedures Order, and from the date of the conclusion of the Auction (as defined in the U.S. Bidding Procedures Order) until the Closing Date or termination of this Agreement, neither any Seller nor any Affiliate of any Seller
shall, directly or indirectly through any of its officers, directors, employees, agents, professional advisors or other representatives (collectively, the Representatives), (i) solicit, initiate or encourage or engage in
discussions or negotiations with respect to any proposal or offer from any Person (other than the Purchaser or its affiliates) relating to in each case any acquisition, divestiture, recapitalization, business combination or reorganization of or
involving all or a substantial part of the business and operations of the Business (a Competing Transaction), (ii) furnish any information with respect to, or participate in, or assist, any effort or attempt by any Person to
do or seek the foregoing, (iii) execute any letter of intent or agreement providing for a Competing Transaction, or (iv) seek or support Bankruptcy Court approval of a motion or Order inconsistent with the transactions contemplated herein
(provided, however, that nothing contained herein shall prohibit the Sellers from providing any Person with the Bidding Procedures and related documents, answering questions about the Bidding Procedures or announcing the execution of
this Agreement or the Auction). Notwithstanding the foregoing, from the date of this Agreement until the entry of the U.S. Bidding Procedures Order, the Sellers may provide continued access to written due diligence materials about the Business in an
electronic data room (including written responses to requests for information made after the date hereof), to only such Person or Persons that (A) have access to such electronic data room as of the date hereof and (B) have satisfied the
requirements of paragraph (a) of the Participation Requirements of the U.S. Bidding Procedures Order within ten (10) Business Days from the date hereof (it being understood that, during such ten (10) Business Day period,
the Sellers will be allowed to (x) request such Persons to enter into amendments to their existing confidentiality agreements in order to render them compliant with the requirements of the U.S. Bidding Procedures, (y) discuss and negotiate
such amendments with those Persons and (z) execute such amendments, and each such action shall not constitute a breach of this Section 5.29); provided, however, that the Sellers must provide the Purchaser at least equivalent
access to all such written due diligence materials. Without prejudice to any other methods or actions that may result in the cure of any breach of this Section 5.29, the Parties acknowledge and agree that in the event that any officer or other
employee of any Seller acting alone (without the assistance of outside advisors) in violation of a corporate policy approved by the board of directors of NNC takes an action that constitutes a breach of clause (i) of this Section 5.29 but
does not constitute a breach of any other clause of this Section 5.29, such breach shall be deemed cured in the event such action ceases and one or more of the Sellers notifies the counterparty or counterparties to the potential Competing
Transaction in writing that the Sellers will not undertake such Competing Transaction, in each case no later than the fifth (5th) day after the Sellers become aware of such breach (for such purposes excluding the knowledge of the employee or
officer whose action constitutes such breach), provided that such action that constituted the breach did not involve substantive negotiations regarding the terms of such Competing Transaction.

SECTION 5.30. Direct Leases.

(a) For each of the properties owned in fee by the Sellers identified on Section 5.30(a) of the Sellers Disclosure Schedule (the Direct Lease Real Estate), Purchaser agrees that
the relevant Seller and Purchaser or a Designated Purchaser will enter into a lease on fair



136



---

market terms for a term of 3 years and otherwise in substantially the form attached hereto as Exhibit N (the Direct Leases) and a notice of lease with respect thereto
for recording in the registry of deeds to the extent possible in each relevant jurisdiction (the Notices of Lease) with respect to the portion of the Direct Lease Real Estate to be leased by the Purchaser or a Designated Purchaser
for the Business.

(b) The Purchaser will have until the relevant Contract Designation Date to elect to have the Purchaser or
a Designated Purchaser enter into a Direct Lease with the relevant Seller at Closing with respect to any properties identified in Section 5.30(b) of the Sellers Disclosure Schedule or with respect to the Owned Real Estate. Following any
election, prior to the relevant Contract Designation Date, by Purchaser to enter into a Direct Lease with respect to the Owned Real Estate or a property identified in such Section 5.30(b), the Owned Real Estate or such site, as applicable,
shall thereafter be deemed included among the Direct Lease Real Estate for all purposes hereunder. It is understood that the Purchaser shall be entitled, by written notice to NNI to elect to remove entirely any Direct Lease Real Estate which had
therefore been set forth in Section 5.30 of the Sellers Disclosure Schedule prior to the applicable Contract Designation Date.

(c) The Sellers obligation to make any Direct Lease Real Estate available to the Purchaser or a Designated Purchaser, either at Closing or during the term of a Direct Lease, 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 Direct Lease Real Estate as the Sellers deem appropriate in their sole discretion, either, at Sellers election,
subject to the related Direct Lease or, in accordance with the requirements of this Section 5.30(c), free and clear of the same. Sellers shall give Purchaser or a Designated Purchaser reasonable prior notice, not less than the number of days
specified in Section 5.30(a) or 5.30(b), as applicable, of the Sellers Disclosure Schedule with respect to such property, of any such disposition of Direct Lease Real Estate, and Purchasers shall be permitted to remain at such property under
the terms of the Direct Lease until the end of the notice period. Sellers only liability to the Purchaser or any other party in the event that any Direct Lease Real Estate with respect to which Purchaser has, prior to the relevant Contract
Designation Date, elected to enter into a Direct Lease is not made available at Closing or, following entry into a Direct Lease, the relevant Seller terminates such Direct Lease in order to sell or otherwise disposes of such Direct Lease Real Estate
free and clear of such Direct Lease shall be to pay the Relocation Costs of Purchaser or Designated Purchaser relating to the relocation of all Assets and business operations required as a result of such sale or other disposition. To the extent that
the relevant Seller sells or otherwise disposes of any Direct Lease Real Estate with respect to which Purchaser has, prior to the relevant Contract Designation Date, elected to enter into a Direct Lease prior to Closing, the relevant Seller and
Purchaser or a Designated Purchaser shall further comply with the requirements of clauses (ii), (iii) and (v) of Section 5.31(g) relating to Mission Critical Leases, to the extent applicable.

(d) Sellers and Purchaser will cooperate to determine how to segregate and demise the leased premises to Purchaser or a Designated Purchaser
(which shall be based upon the contemplated use of the demised premises and employee headcount reasonably agreed between Purchaser and Sellers on or prior to the Closing Date and shall also take into account the continued marketability and required
contiguity of those portions of such Direct Lease Real



137



---

Estate to be subject and not to be subject, respectively, to the related Direct Lease) and provide relevant information (subject to confidentiality limitations) on the Direct Lease Real Estate to
the other provided that it is understood and agreed that all costs of such segregation and demising will be the sole responsibility of Purchaser and that Purchasers plans and specifications therefor will be subject to Sellers reasonable
approval.

SECTION 5.31. Rejection and Expiration of Real Estate Leases.

(a) Notwithstanding any provision of this Agreement to the contrary, it is understood and agreed that the Sellers obligations to
(i) assign any 365 Real Estate Lease to the Purchaser or a Designated Purchaser and (ii) enter into or continue to sublease pursuant to a Sublease under any Assumed and Subleased Real Estate Lease (the Conditional
Subleases) shall be subject to the Sellers right to reject such 365 Real Estate Lease (including Assumed and Subleased Real Estate Leases) at any time on or before the Latest Lease Rejection Date, except, only in the event the
Purchaser exercises its election under Section 2.1.5(b)(v) to remove all Assets, Employees and operations relating to the Business from the premises covered by the Lease identified as Lease B on Section 2.1.5(b)(iii) of the Sellers
Disclosure Schedule, which is governed by Section 2.1.5(b)(v). The Sellers may exercise such right to reject any 365 Real Estate Lease and, as applicable, either be relieved of their obligation to assign such 365 Real Estate Lease to the
Purchaser or a Designated Purchaser or terminate, or be relieved of their obligation to enter, the related Conditional Sublease at any time following the execution of this Agreement, including, as applicable, following the execution of such
Conditional Sublease with the Purchaser or a Designated Purchaser (provided that after Closing, the Sellers will not reject any 365 Real Estate Leases that are Assumed and Assigned Contracts).

(b) In each instance in which a Seller on or before the applicable Latest Lease Rejection Date, in its sole discretion, rejects a 365 Real
Estate Lease that Sellers would otherwise be obligated to assign to the Purchaser or a Designated Purchaser or under which Sellers would otherwise be obligated to enter into a Sublease,

(i) Sellers will provide Purchaser a copy of the rejection notice delivered to the relevant landlord; provided that no
failure to provide any such copy shall impair or impact the effectiveness of such rejection;

(ii) except as
provided in Section 5.31(g) with respect to Relocation Costs, no reimbursements for any costs, expenses or damages shall be payable by any Seller or any of their Affiliates to Purchaser, any Designated Purchaser, any of their Affiliates or any
other Person as a result of such rejection; provided that if the Seller performs the relocation of Assets, Employees or business operations in connection with any such rejection occurring after the Closing that, individually or in the aggregate with
other relocations, has a Material Adverse Effect, then, to the extent that such Material Adverse Effect resulted from Sellers gross negligence in performing such relocation, Seller shall be responsible for the Relocation Damages resulting
therefrom;

(iii) Sellers agree that such rejection shall only be effective (except with respect to Mission
Critical Leases, as to which the terms of Section 5.31(g)



138



---

shall apply) upon reasonable prior notice to Purchaser from Sellers, no less than ten days following Sellers notification to Purchaser of the same, and termination of the related
Conditional Sublease (as applicable) shall be effective upon reasonable prior notice from Sellers, no less than nine days following Sellers notification to Purchaser of the same; provided, however, that any rejection of the 365 Real Estate
Lease identified in Section 2.1.5(b)(iv)(B) of the Sellers Disclosure Schedule shall only be effective, to the extent that such 365 Real Estate Lease becomes an Assumed and Subleased Real Estate Lease hereunder, on not less than one year
notice;

(iv) Purchaser shall be relieved of its obligation to accept assignment or enter into a Sublease with
respect to the applicable 365 Real Estate Lease; and

(v) the Sellers will cooperate with Purchaser or a
Designated Purchaser and use commercially reasonable efforts, in each instance, to minimize the disruption to the affected business operations as a result of any rejections.

(c) If the rejection is effective on or prior to Closing, Seller will give Purchaser access to the subject premises for not less than ten
(10) Business Days after receipt of the rejection 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 Sellers sole cost and expense 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 at Closing unless the same are included in the Assets and are specifically identified by Purchaser for removal). It is further understood that transfer of the 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 or a Designated 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 within ten (10) Business Days that it wishes to have stored within the above time
frame, the Sellers shall be entitled to abandon or otherwise dispose of such Assets in their sole discretion without any liability to Purchaser.

(d) If a rejection of an Assumed and Subleased Real Estate Lease is effective after Closing, subject to the provisions of Section 5.31(g) with respect to Mission Critical Leases, the Purchaser agrees
to, or to cause a Designated Purchaser to, vacate the premises which are subject to such Conditional Sublease in conformance with the requirements of the relevant Assumed and Subleased Real Estate Lease and as otherwise required by such Conditional
Sublease.

(e) In connection with any 365 Real Estate Lease as to which the Sellers give a notice of rejection, at the
Purchasers option and written request and sole cost and expense exercised within ten (10) Business Days following receipt of the rejection notice referred to above, the Sellers will reasonably cooperate (without incurring any third-party
costs) with the Purchasers efforts to enter into a new lease with respect to all of the subject premises directly with the relevant landlord (it being agreed that Sellers shall have no obligations under or with



139



---

respect to any such direct lease). Purchaser further acknowledges that the Sellers have requested the agreement of the landlord under each Designated 365 Real Estate Lease and Assumed and
Subleased Real Estate Lease to an extension of the relevant Latest Lease Rejection Date to a date beyond the latest date when the parties estimate a Closing might reasonably occur, provided that it is agreed that, other than for Mission Critical
Leases:

(i) should any such landlord agree to such extension, then at Purchasers election exercised
within ten (10) Business Days following notice by Sellers of such extension and Sellers intention to reject, the applicable 365 Real Estate Lease will be deemed an Assumed and Assigned Lease and Purchaser shall take an assignment of such
365 Real Estate Lease at Closing (regardless of whether such lease was designated as of the date hereof for assignment or for entry into a Sublease) and Purchaser shall pay Sellers, irrespective of whether Closing subsequently occurs, (A) at
the time of such agreement by landlord, one hundred percent (100%) of any extension or option fees imposed by such landlord or otherwise payable by Sellers and (B) prior to the date upon which any such payments are due to landlord, fifty
percent (50%) of all of Sellers actual, out of pocket rent and other occupancy costs under such 365 Real Estate Lease through Closing (regardless of whether all such space is used by the Business as of the date of this Agreement); and

(ii) should such landlord refuse to agree to such extension, or if Closing does not occur on or before the
Latest Lease Rejection Date as extended, or if Purchaser elects not to take an assignment of such 365 Real Estate Lease, Sellers shall be free to reject such 365 Real Estate Lease in accordance with the provisions set forth above.

(f) In the case of Real Estate Leases scheduled to expire prior to the Closing that the Sellers are not otherwise planning to extend, at the
request of the Purchaser or a Designated Purchaser, the Sellers will use commercially reasonable efforts, without incurring third party costs, to obtain the agreement of the relevant landlord to a short-term extension of the relevant lease
expiration date to a date beyond the latest date when the parties estimate a Closing might reasonably occur, provided it is agreed that:

(i) should such landlord agree to such extension, Purchaser or a Designated Purchaser shall take an assignment of such Real Estate Lease at Closing (regardless of whether such lease was designated as of
the date hereof for assignment or for entry into a Sublease) and Purchaser shall pay Sellers, irrespective of whether Closing subsequently occurs, (A) at the time of such agreement by landlord, one hundred percent (100%) of any extension
option fees, increased rent or other increased occupancy costs imposed by such landlord or otherwise payable by Sellers and (B) prior to the date upon which any such payments are due to landlord, fifty percent (50%) of all of Sellers
actual, out of pocket rent and other occupancy costs (without taking into account any increased charges which are the subject of (A) above) under such 365 Real Estate Lease through Closing (regardless of whether all such space is used by the
Business as of the date of this Agreement); and



140



---

(ii) should such landlord refuse to agree to such extension, or if Closing
does not occur on or before the extended expiration date of such lease, Sellers shall be free to allow such lease to expire.

(g) Notwithstanding anything to the contrary in this Agreement, if the Sellers elect to reject any Designated 365 Real Estate Lease or Assumed and Subleased Real Estate Lease identified in Section 5.31(g) of the Sellers Disclosure
Schedule (collectively, the Mission Critical Leases),

(i) in the case of any rejection
which is to be effective prior to Closing, Sellers will give Purchaser or a Designated Purchaser reasonable prior notice, not less than thirty (30) days subject to Sellers obligations pursuant to Section 5.31(g)(v) (subject to
Sellers obligation to comply with their covenant in Section 5.31(g)(ii)), of their intent to reject such Mission Critical Lease and will provide Purchaser or such Designated Purchaser a copy of the rejection notice; provided that
no failure to provide any such notice or copy shall impair or impact the effectiveness of such rejection;

(ii)
in the case of any rejection which is to be effective prior to Closing, the relevant Seller and the Purchaser or a Designated Purchaser shall convene to discuss and agree on a mutually acceptable strategy for negotiating and entering into an
Equivalent Lease for Equivalent Space, including without limitation determining whether a Seller or the Purchaser will be the tenant under such Equivalent Lease, which party will enter into a lease, sublease or other arrangement for temporary space,
which may include corporate office sharing, home-basing or other similar alternative arrangements (each, a Temporary Lease), and which party will be primarily responsible for the negotiations of the Equivalent Lease and/or the
Temporary Lease. Both parties will have a reasonable opportunity to participate in the negotiations for the Temporary Lease and the Equivalent Lease. If a Temporary Lease is to be entered into, it will be sufficient, throughout the temporary
occupancy period and until the Purchaser or a Designated Purchaser is able to commence operations at the Equivalent Space, to reasonably continue operation of the Business conducted at the property subject to the rejected Mission Critical Lease in
the manner in which the same is conducted at such property on the date of this Agreement, taking into account the agreement of Purchaser and Sellers to minimize the costs associated with outfitting such alternative temporary space. If the Sellers
enter into an Equivalent Lease or a Temporary Lease, such Equivalent Lease or Temporary Lease shall, following its execution, be deemed an Included Real Estate Lease for all purposes hereunder and shall be assigned to the Purchaser or a Designated
Purchaser at Closing. If the Purchaser or a Designated Purchaser enters into an Equivalent Lease or a Temporary Lease prior to Closing, the Purchaser or a Designated Purchaser and the Sellers will enter into a sublease thereof on terms to be
reasonably agreed between the parties (it being understood that the occupancy costs under such sublease shall be set so that Purchaser is merely passing through such costs under such Equivalent Lease or Temporary Lease) for the term of the
Equivalent Lease or Temporary Lease, with respect to the property covered by



141



---

such Equivalent Lease or Temporary Lease, provided that (A) the Sellers will post a letter of credit covering the rent and other occupancy costs due under such sublease during the term
thereof, (B) the sublease will provide that it will terminate at the Closing, if the Closing occurs, and (C) nothing herein shall be construed to require either party to enter into or assume any liability with respect to an Equivalent
Lease or any sublease thereunder prior to Closing so long as other means of reasonably continuing operation of the Business conducted at the property subject to the rejected Mission Critical Lease substantially in the manner in which the same is
conducted at such property on the date of this Agreement are available including but not limited to entry into a Temporary Lease prior to Closing followed by entry into an Equivalent Lease following Closing;

(iii) in the case of any rejection which is to be effective prior to Closing, the Sellers shall relocate the Assets,
Employees and business operations at their sole cost and expense from the property subject to the rejected Mission Critical lease into the property subject to the Temporary Lease or into the Equivalent Space on or prior to the effective date of the
rejection in such a manner as to reasonably permit the continued operation of the Business conducted at the property subject to the rejected Mission Critical Lease. If a Temporary Lease is entered into, the Sellers will relocate the Assets,
Employees and business operations at their sole cost and expense from the property subject to the Temporary Lease into the Property subject to Equivalent Space. The occupancy and operating costs under the Temporary Lease or Equivalent Lease and the
property subject thereto shall be borne by Sellers for all periods up to the Closing Date, either directly, if the Sellers enter into such Temporary Lease or Equivalent Lease, or via a sublease as described above, if the Purchaser enters into such
Temporary Lease or Equivalent Lease. If such Temporary Lease remains in place after the Closing Date, the occupancy and operating costs under the Temporary Lease and the property subject thereto for the period after Closing shall be borne
exclusively by Purchaser, unless and until Purchaser has entered into and commenced paying rent and occupancy costs on an Equivalent Lease, in which case the Sellers shall pay fifty percent (50%) of the rent and occupancy costs under the
Temporary Lease for six months commencing on the date on which Purchaser commences monthly rental payments under the Equivalent Lease. If such Temporary Lease remains in effect after the Closing, Purchaser shall diligently pursue its procurement of
Equivalent Space to which to relocate the Assets, Employees and business operations subject to the terms of this Section 5.31(g);

(iv) in the case of any rejection which is to be effective prior to Closing, the Sellers shall pay all Relocation Costs of Purchaser or Designated Purchaser relating to the relocation of all Assets,
Employees and business operations required as a result of said rejection, including without limitation any relocation of all Assets, Employees and business operations from the property subject to the rejected Mission Critical Lease to the property
subject to the Temporary Lease and, thereafter, to Equivalent Space; provided that Sellers shall not be required to compensate Purchaser or any other party for any other amounts



142



---

or damages of any kind in connection with such relocation except as expressly set forth in Section 5.31(b)(ii), including but not limited to as a result of any difference in the economic
terms of the rejected Mission Critical Lease and any new Equivalent Lease entered into by Purchaser or an Affiliate of Purchaser;

(v) the Sellers shall cooperate with Purchaser or a Designated Purchaser and use reasonable efforts, in each instance to minimize the disruption to the affected business operations as a result of such
relocation;

(vi) notwithstanding the foregoing, if the Sellers elect to reject, effective on or after the
Closing Date, a Mission Critical Lease, (A) the Sellers will give the Purchaser or a Designated Purchaser reasonable (but in no event less than thirty (30) days) prior notice (provided that thirty days is sufficient notice for Sellers to
comply with their covenant in Section 5.31(g)(v)), of their intent to reject such Mission Critical Lease and will provide the Purchaser or such Designated Purchaser a copy of the rejection notice (provided that no failure to provide any such
notice or copy shall impair or impact the effectiveness of such rejection), (B) the Seller and the Purchaser or a Designated Purchaser shall convene to discuss and agree on a mutually acceptable strategy for negotiating a lease for Equivalent
Space, (C) the Purchaser or such Designated Purchaser and the Sellers shall cooperate to make arrangements for securing Equivalent Space and the relocation of all Assets and business operations thereto, (D) the Seller shall cooperate with
Purchaser or a Designated Purchaser and use commercially reasonable efforts, in each instance to minimize the disruption to the affected business operation as a result of such relocation, and (E) the Sellers shall pay all Relocation Costs of
the Purchaser or such Designated Purchaser relating to the relocation to Equivalent Space of all Assets, Employees and business operations required as a result of said rejection, including without limitation any relocation of all Assets, Employees
and business operations from the property subject to the rejected Mission Critical Lease to the property subject to the Temporary Lease and, thereafter, to Equivalent Space; provided that Sellers shall not be required to compensate Purchaser or any
other party for any other amounts, including but not limited to as a result of any difference in the economic terms of the rejected Mission Critical Lease and any new lease entered into by Purchaser or an Affiliate of Purchaser; and provided further
if Purchaser has commenced paying rent and occupancy costs on a lease for Equivalent Space, Sellers shall be obligated to pay fifty percent (50%) of the rent and occupancy costs under the related Temporary Lease, if applicable, for six months
commencing on the date on which Purchaser commences monthly rental payments under the lease for Equivalent Space. If Purchaser or an Affiliate of Purchaser enters into a Temporary Lease following a rejection, effective on or after the Closing Date,
of a Mission Critical Lease, Purchaser shall diligently pursue its procurement of Equivalent Space to which to relocate the Assets, Employees and business operations subject to the terms of this Section 5.31(g);

(vii) if the Sellers elect to reject Lease C, the provisions of Exhibit 5.32(c) shall apply in addition to the
provisions of this Section 5.31(g).



143



---

Notwithstanding the foregoing, if Purchaser elects, pursuant to Section 2.1.5(b)(v), neither to take an
Assignment of Lease B nor to remove all Assets, Employees, and operations relating to the Business from the premises covered by such Lease B and Sellers elect to reject Lease B, Purchaser agrees that Sellers obligation to pay Relocation Costs
of Purchaser or Designated Purchaser shall be limited to the relocation of Assets, Employees and business operations located as of the date of this Agreement in the premises indicated in Exhibit 2.1.5(b)(v).

(h) If the relevant landlord has refused to provide its required Consent to a Sublease under a Mission Critical Lease or does not respond to
a request for such Consent, then the Sellers shall pay all Relocation Costs of Purchaser or Designated Purchaser relating to the relocation of all Assets and business operations required as a result of Sellers inability to enter into such
Sublease; provided that Sellers shall not be required to pay any Relocation Costs of Purchaser or any other party in any instance where a landlord under a Mission Critical Lease has refused to deliver a required Consent as a result of
Purchasers or a Designated Purchasers refusal or other failure to comply with the provisions of Section 5.4 of the Sellers Disclosure Schedule; and provided further that Sellers shall not be required to compensate Purchaser or any
other party for any other amounts, including but not limited to as a result of any difference in the economic terms of the relevant Mission Critical Lease and any new lease entered into by Purchaser or an Affiliate of Purchaser and provided further
that Sellers and Purchaser or a Designated Purchaser shall be obligated to comply with the requirements of Section 5.13 prior to the completion of such relocation.

SECTION 5.32. Restructure of Leases.

(a) The Purchaser acknowledges that
the Sellers have commenced negotiations with certain of the landlords under certain 365 Real Estate Leases and Non-365 Real Estate Leases with the intention of agreeing to modifications of such Real Estate Leases. The Purchaser agrees that the
Sellers shall be permitted to restructure the 365 Real Estate Leases and the Non-365 Real Estate Leases, including to reduce the size of the premises demised thereby and to vacate one or more buildings covered by single Real Estate Leases, and, in
connection therewith, at the Sellers sole cost and expense, to relocate applicable Employees, Assets and business operations within the facilities subject to such Real Estate Leases (including, in the case of Sellers operations at the C
Campus as defined in Section 5.32(c) of the Sellers Disclosure Schedule, relocation of Employees, Assets and business operations between facilities covered by separate Real Estate Leases) so long as:

(i) the space made available to the Purchaser at Closing under such Real Estate Lease contains usable and rentable square
footage sufficient to reasonably support the contemplated use of the demised premises and employee headcount reasonably agreed between Purchaser and Sellers on or prior to the Closing Date and to conduct the Business at such premises in a manner
substantially similar to the manner conducted at such premises (and any adjacent premises from which Employees, Assets and business operations are being transferred) as of the date hereof and such space is not divided into two or more non-contiguous
portions,



144



---

(ii) upon Purchasers request, the relevant Seller and the Purchaser
shall convene to discuss and agree on a mutually acceptable strategy for approaching such negotiations with the relevant landlord and Purchaser shall provide the relevant Seller with a detailed description of its contemplated use of the premises and
employee headcount and space needs (subject to reasonable confidentiality limitations),

(iii) the occupancy
costs or security deposit to the Purchaser or a Designated Purchaser at such real property shall not be increased in any material respect over what they would be in the absence of such amendment of such Real Estate Leases, it being agreed
specifically that Purchaser or a Designated Purchaser shall be subject to no increased security deposit requirements as a result of such amendment,

(iv) the Sellers shall pay all Relocation Costs of the Purchaser or Designated Purchaser relating to the relocation required as a result of said restructuring,

(v) except as provided in Section 5.32(a)(iv) with respect to Relocation Costs, no reimbursements for any costs,
expenses or damages shall be payable by any Seller or any of their Affiliates to Purchaser, any Designated Purchaser, any of their Affiliates or any other Person as a result of such restructuring; provided that if the Seller performs the relocation
of Assets, Employees or business operations in connection with any such restructuring occurring after the Closing that, individually or in the aggregate with other relocations, has a Material Adverse Effect, then to the extent that such Material
Adverse Effect resulted from Sellers gross negligence in performing such relocation, Seller shall be responsible for the Relocation Damages resulting therefrom; and

(vi) the Sellers shall cooperate with Purchaser or a Designated Purchaser and use reasonable efforts, in each instance, to
minimize the disruption to the affected business operations as a result of such relocation.

(b) In the event that Sellers
have not, prior to Closing, completed the consolidation of operations at any premises pursuant to a restructure of an Assumed and Subleased Real Estate Lease or Non-365 Subleased Real Estate Lease, the relevant Seller and Purchaser or Designated
Purchaser shall enter into the contemplated Sublease on the Closing Date but, prior to the completion of such consolidation, such Seller shall make available in lieu of the premises which are to be the subject of such Sublease alternative space at
the same facility designated by such Seller (the Relocation Space) in a notice given to Purchaser or Designated Purchaser from which the impacted business operations can be conducted. The Relocation Space shall be reasonably
comparable to the premises which are the subject of such Sublease with respect to internal configuration, quality of finish and rentable square foot area (i.e., plus or minus ten (10%) percent). Such Seller shall, at such Sellers cost and
expense, complete the build-out of the premises which are to be the subject of the Sublease and, following the same, remove and reinstall Purchasers or Designated Purchasers personal property, trade fixtures and



145



---

equipment in such premises as promptly as reasonably practicable provided that Purchaser or Designated Purchaser cooperates with such Seller and gives such Seller full access to the
premises which are to be the subject of such Sublease in order to facilitate the performance of such required work. During such entire period, Purchaser or Designated Purchaser shall be obligated to pay all rent and additional rent required under
the terms of such Sublease but not with respect to the Relocation Space, regardless of whether Purchaser or Designated Purchaser is then occupying the premises which are to be the subject thereof.

(c) The Sellers shall consolidate the C Campus (as defined in Section 5.32(c) of the Sellers Disclosure Schedule) in accordance with
the provisions of Exhibit 5.32(c), subject to the rights of the Sellers in Section 5.31.

SECTION 5.33.
Non-Compete. Except as permitted pursuant to Section 5.25(b) with respect to any Excluded Sellers, for a period of three (3) years from and after the Closing Date, none of the Sellers shall, or shall permit or cause any of their
Wholly-Owned Subsidiaries to, (i) sell a product or service competitive with any product or service contemplated in the definition of the Business in any geographic area in which the Business is conducted on the date hereof (unless purchased
from the Purchaser or a Designated Purchaser), or (ii) acquire or hold voting securities of any Person that is engaged in a business competitive with the Business as conducted on the date hereof, provided that the foregoing restrictions
shall not prohibit or restrict (a) performance by the Sellers under the Rejected Customer Contracts, through the subcontract arrangement contemplated by Section 5.14(b) or 5.14(c), as applicable, if such arrangement is entered into
pursuant to the provisions therein, or otherwise if such arrangement is not entered into, (b) the acquisition or holding of a passive investment in up to 5% of the outstanding stock of a corporation that does not give such Seller or
Wholly-Owned Subsidiary of such Seller the right to appoint directors or management of such Person or to otherwise exercise control over the management of such Person, (c) the passive holding of the securities any of the Sellers owns as of the
date hereof and the holding of the equity interests in the joint ventures listed in Section 1.1(a) of the Sellers Disclosure Schedule that the Sellers own as of the date hereof or (d) the sale of Sellers Converging Products. In the
event that any Seller or any Wholly-Owned Subsidiary of any Seller is acquired by, merged with or otherwise combined with (whether in a single transaction or a series of related transactions or whether structured as an acquisition of assets,
securities or otherwise) (any such transaction, a Seller Acquisition) any other Person (an Acquiring Person), the provisions of this Section 5.33 shall not restrict the ability of the Acquiring Person or
its Affiliates to continue to operate the type of business or own the type of assets that they respectively operated or owned prior to the Seller Acquisition. If the final judgment of a court of competent jurisdiction declares that any term or
provision of this Section 5.33 is invalid or unenforceable, the parties hereto agree that the court making the determination of invalidity or unenforceability will have the power to reduce the scope, duration, or area of the term or provision,
to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or
provision, and this Agreement will be enforceable as so modified after the expiration of the time within which the judgment may be appealed.

SECTION 5.34. Financial Statements.

(a) Subject to the last sentence of this Section 5.34(a), the Main Sellers shall provide the Audited Financial Statements and the
Audited 2009 Interim Financial Statements to the Purchaser as promptly as reasonably practicable, but in any event no later than (i) July 31, 2009, in the case of the Audited Financial Statements and, (ii) subject to

the case of the September 30, 2009 Unaudited Interim Financial Statements, and (iii) if the Registration Statement is not effective or the Closing Date is on or after May 11, 2010, by May 30, 2010 in the case of the
March 31, 2010 Unaudited Interim Financial Statements. Notwithstanding the foregoing or any other provision of this Section 5.34, and in any event, the Main Sellers shall deliver to the Purchaser prior to the Closing all Audited Financial
Statements, Audited 2009 Interim Financial Statements, Additional Audited 2009 Financial Statements and all Unaudited Interim Financial Statements in respect of fiscal quarters ended prior to the Closing Date that are required to be included in the

Statement), or any current report on Form 8-K required to be filed by the Purchaser or any of its affiliates under the Securities Exchange Act of 1934 with respect to the transactions contemplated by this Agreement (the
8-K).

(b) For forty-five (45) days from the date hereof or, if the Registration Statement has been
filed as of the date hereof or is filed within fifteen (15) days of the date hereof, for forty-five (45) days from the date the SEC notifies the Purchaser (or one of its affiliates) as to whether the SEC will review the Registration
Statement, the Purchaser shall use its commercially reasonable efforts to obtain as promptly as practicable from the SEC a waiver with respect to any requirement to include audited financial statements other than the Audited Financial Statements in
the Registration Statement and the 8-K (and in connection therewith shall use its commercially reasonable efforts to prepare applicable materials (as determined by Purchaser) for submission to the SEC as promptly as practicable). The Purchaser shall
keep the Main Sellers promptly informed of any material developments in its discussions with the SEC regarding such waiver. If the Purchaser obtains such waiver in respect of both the Registration Statement and the 8-K, then the Main Sellers shall
not be required to deliver the Audited 2009 Interim Financial Statements pursuant to the provisions of Section 5.34(a), but may nonetheless be required to deliver such Audited 2009 Interim Financial Statements pursuant to the provisions of
Section 5.34(d)(ii).

148



---

(f) If any financial statements or Information required to be delivered pursuant to
Section 5.34(d) have not been delivered prior to Closing, the Purchaser shall deliver an amount equal to the Holdback Escrow Amount to the Escrow Agent at Closing and the Holdback Escrow Amount shall be held by the Escrow Agent in accordance
with this Agreement and the Escrow Agreement. If the Main Sellers are required to deliver any financial statements or Information pursuant to Section 5.34(d) and the Main Sellers (i) do not engage KPMG for purposes of auditing any of these
financial statements or Information that are required to be audited financial statements or (ii) do not deliver such financial statements or deliver them more than twenty-five (25) days later than the dates provided in
Section 5.34(e)(ii) or Section 5.34(e)(iii), as applicable, then the Holdback Escrow Amount (together with any actual interest earned thereon) shall be returned to the Purchaser by the Escrow Agent.

(g) In the event that following the Closing (A) the Main Sellers will not be required to deliver to the Purchaser any financial
statements pursuant to Section 5.34(d) or (B) the Main Sellers have complied with the obligations set forth in Section 5.34(d) and Section 5.34(e), as applicable, then the Purchaser shall promptly instruct the Escrow Agent to
immediately release the Holdback Escrow Amount to the Distribution Agent (as agent for the Sellers and the EMEA Sellers).

(h)
The Main Sellers shall cooperate in Purchasers efforts to obtain consent from Sellers independent auditors for the inclusion of the Audited Financial Statements and, if applicable, the Audited 2009 Closing Date Financial Statements, the
Audited 2009 Interim Financial Statements and/or the Additional Audited 2009 Financial Statements in any registration statement or other filing with the SEC. Subject to the limitations set forth in Section 5.6 (except that the Main Sellers
acknowledge and agree that such information as is necessary to be included in a registration statement or other filing with the SEC need not be kept confidential by the Purchaser), the Main Sellers shall provide the Purchaser, the relevant
Designated Purchasers and their representative accountants reasonable access to the books, records and personnel of the Business and the Companies and all documents, schedules and work papers that are reasonably necessary to prepare any financial
statements that are required to be delivered pursuant to the terms of this Section 5.34. The Sellers shall reasonably cooperate in the Purchasers efforts, whether pre- or post-Closing, to prepare the Registration Statement, the 8-K and
any other filings with the SEC that are required to include any financial statements of the Business (or portion thereof), provided that such reasonable assistance shall include providing the Purchaser, the relevant Designated Purchasers and their
representative accountants reasonable access to the books, records and personnel of the Business and the Companies and all documents, schedules and work papers that are reasonably necessary to prepare the Audited Financial Statements, the Unaudited
Interim Financial Statements, any quarterly combined income statement information of the Business, the income statement information from the date of the last interim balance sheet required to be delivered to the Purchaser through the Closing Date,
the pro forma financial statements of the combined entity and, if applicable, the Audited 2009 Closing Date Financial Statements, the Audited 2009 Interim Financial Statements and/or the Additional Audited 2009 Financial Statements, together with
any related financial disclosures to be included in the Registration Statement or other filing with the SEC.

(i) If the
Audited 2009 Interim Financial Statements are required to be provided pursuant to the provisions of Section 5.34(a), the Purchaser shall use its commercially



149



---

reasonable efforts to obtain as promptly as practicable a determination from the SEC with respect to whether the Audited 2009 Interim Financial Statements must include combined statements of
income and cash flows and footnote information for the nine month period ended September 30, 2008 to meet the requirements of Regulation S-X and Rule 3-05 thereunder, for inclusion in the Registration Statement and the 8-K. The Purchaser shall
keep the Main Sellers promptly informed of any material developments in its discussions with the SEC regarding such determination. If the Purchaser obtains a determination that such combined statements of income and cash flows and footnote
information for the nine month period ended September 30, 2008 are not required to meet the requirements of Regulation S-X and Rule 3-05 thereunder, for inclusion of the Audited 2009 Interim Financial Statements in the Registration Statement
and the 8-K, then the Main Sellers shall not be required to deliver the combined statements of income and cash flows and footnote information for the nine month period ended September 30, 2008 with the Audited 2009 Interim Financial Statements
pursuant to the provisions of Section 5.34(a), but may nonetheless be required to deliver such combined statements of income and cash flows and footnote information for the nine month period ended September 30, 2008 with the Audited 2009
Interim Financial Statements pursuant to the provisions of Section 5.34(d)(ii).

SECTION 5.35. Certain
Acknowledgements Regarding PBGC. The Purchaser acknowledges and agrees that none of the actions or occurrences referred to in clauses (i) through (iv) of Section 8.3(d) hereof in and of itself shall constitute or be construed as a
breach by any of the Sellers of any of their representations, warranties, covenants or agreements set forth in this Agreement or any other Transaction Document. Notwithstanding the foregoing, nothing in this Section shall limit or be construed as
limiting the scope, application or effect of Section 8.3(d). To the extent the PBGC terminates the NNRIP (or any other Seller Employee Plan) or imposes any Lien on the assets of any of the Companies or any of the Sellers, or in the event of any
other action or occurrence referred to in clauses (i) through (iv) of Section 8.3(d), then the Parties shall use their reasonable best efforts to take, or cause to be taken, all actions to do, or cause to be done, and cooperate with
each other in order to do, all things necessary, proper or advisable to obtain from the PBGC a waiver of its Claims against Purchaser, its Affiliates (including the Companies) or the holder of any Assets in connection with the NNRIP and a release of
such Lien in order to cause the satisfaction of the condition set forth in Section 8.3(d) at the earliest practicable date; provided that the Purchaser shall not be required to make any payment, relinquish any right, or deliver or
relinquish anything of value in order to obtain such waiver (other than payment of the Purchase Price).

SECTION 5.36.
Finalization of Transition Services Agreement.

(a) The Parties acknowledge that Schedule 1 (the Schedule 1
Included Services), Schedule 5 and Schedule 6 (collectively, the General Scope of Services) attached to the form Transition Services Agreement contained in Exhibit P hereto reflects the general scope of certain
services to be provided pursuant to the Transition Services Agreement by the TSA Sellers and TSA EMEA Sellers (and may reflect greater detail as to some of such services), but is not sufficiently refined to define all such services in operational
detail. Accordingly, the Parties agree that, between the time of the execution of this Agreement and two Business Days prior to the Closing Date, they (i) will negotiate in good faith and use reasonable efforts expeditiously to refine the
description of the services included within the General Scope of Services so as to provide sufficient operational detail (as mutually agreed or as determined by



150



---

arbitration in accordance with clause (h), the Included Services) and (ii) will provide each other with such information that is reasonably requested in connection with
such negotiation. The Parties agree that Included Services will be finally determined prior to Closing by such negotiation or by arbitration in accordance with this Section 5.36, provided that the Included Services will be consistent with, and
will omit any services not reasonably within the service description categories contained in, the General Scope of Services. The Parties further agree that such negotiation and arbitration will be subject to the following general limitations and
conditions (the Scope Guidelines): (i) the Included Services will exclude any portion of any service that has at no time on or after April 1, 2009 been provided by any Seller or any EMEA Seller (or any Affiliate of any
of them) nor provided or procured by any Seller or any EMEA Seller (or any Affiliate of any of them) from a third party (the services within the General Scope of Services that have been provided either by such a Seller or any EMEA Seller (or any
Affiliate of any of them) entity or by a third party at any time on or after April 1, 2009, the Current Services) (it being understood and agreed that (a) each Seller under the Transition Services Agreement will be
committed reasonably to cooperate with Purchaser to coordinate interaction, execution and process steps so that the services of such Seller are delivered in a manner to facilitate the orderly transition of the Business to the Purchaser and
(b) from and after the time of execution of this Agreement until the Closing, the Sellers, the EMEA Sellers and their respective Affiliates will provide, or cause to be provided, to the Business the Current Services, subject to modifications
that would be permitted if the Transition Services Agreement were currently in effect), (ii) if and to the extent that employees of a Seller or an EMEA Seller or a Subsidiary of a Seller or an EMEA Seller performing services as of the date of
execution of this Agreement are Transferred Employees under this Agreement or Transferring Employees under the EMEA Asset Sale Agreement, then the human tasks formerly undertaken by such Transferred Employees or Transferring Employees will no longer
be required to be provided under the Transition Services Agreement (but equipment, licenses and other resources not transferred shall, in accordance with the terms of the Transition Services Agreement, continue to be made available as necessary to
perform such tasks under the Transition Services Agreement as contemplated by this Section 5.36), and (iii) services will be limited to those reasonably advisable to carry on the Business after the Closing in a manner consistent with the
operation of the Business at the time of execution of this Agreement. It is understood and agreed that the services described in the General Scope of Services attached to the Transition Services Agreement have all been provided by or procured by a
Seller or an EMEA Seller (or a respective Affiliate) to or for the Business after April 1, 2009. On the Closing Date but before the Closing, the TSA Sellers and the TSA EMEA Sellers shall be ready, willing and able to satisfy their obligations
pursuant to the Transition Services Agreement in all material respects and the Main Sellers will deliver a certificate to the Purchaser to that effect.

(b) If, between the time of execution of this Agreement and Closing, Purchaser identifies services not described within the General Scope of Services which are reasonably advisable in order to assist with
the orderly transition of the Business to the Purchaser, then the Parties agree that such additional services (defined in operational detail as described herein) will be provided under the Transition Services Agreement, and the Parties will
negotiate in good faith and use reasonable efforts expeditiously to refine such additional services in operational detail consistent with the Scope Guidelines specified in Section 5.36(a) (as mutually agreed or as determined by arbitration in
accordance with clause (h), the Type 1



151



---

Extra Services). If, between the time of the execution of this Agreement and Closing, Purchaser identifies further services reasonably advisable to carry on the Business which are
not described within the General Scope of Services and which are not consistent with the Scope Guidelines, but which can reasonably be provided by the applicable Seller (but not an EMEA Seller) without hiring new employees and without materially
changing or burdening the operations of such Seller, then the Parties agree that such further services (defined in operational detail as described herein) will be provided under the Transition Services Agreement, and the Parties will negotiate in
good faith and use reasonable efforts expeditiously to define such ancillary services in operational detail (as mutually agreed or as determined by arbitration in accordance with clause (h), Type 2 Extra Services; together with
Type 1 Extra Services, the Extra Services).

(c) The Parties acknowledge and agree that, subject to the
provisions below, the Included Services ultimately provided under the Transition Services Agreement are to be billed by the applicable TSA Seller or TSA EMEA Seller under the Transition Services Agreement to the Purchaser at the Direct
Cost of such Included Services as specified in the Transition Services Agreement. However, the Parties further agree that, from and after the execution of this Agreement, they will negotiate in good faith to quantify and stipulate by mutual
agreement the Direct Cost of each such Included Service as a specific monetary amount for each such Service (the Monetary Cost of such Service); provided, that Monetary Cost shall exclude Special Third-Party Costs (as defined in
the Transition Services Agreement). Notwithstanding the foregoing, upon mutual agreement (or resolution by arbitration as provided herein) as to Monetary Cost for any Service under the Transition Services Agreement, the price for such Service shall
thenceforth equal the sum of such Monetary Cost plus Special Third-Party Costs (as defined in the Transition Services Agreement) allocable to such Service, and such price will apply regardless of the Direct Cost actually incurred by the applicable
Sellers under the Transition Services Agreement in providing such Service. The Parties acknowledge that attached to the form of Transition Services Agreement in Exhibit P is (1) a schedule showing an assumed volume of product flow
through the order-to-cash cycle (reflecting both timing and amounts of products) over the 12-month period following Closing (the Product Volume Forecast), (2) a schedule showing an assumed headcount for personnel constituting
Active Employees and employees of Contract Service Providers as defined in the Transition Services Agreement (the IT Headcount Forecast), and (3) the estimated cost of providing services to support the
product flow contemplated by the Product Volume Forecast, consistent with the IT Headcount Forecast, during the 12-month period following Closing (the Estimated Cost Schedule, as revised in accordance with Section 5(a) of the
Transition Services Agreement to account for TUPE Employees. Notwithstanding anything to the contrary in this Agreement or in the Transition Services Agreement, the Parties agree that the outcome of the price negotiation described above in this
Section 5.36(c) (or determined by arbitration as provided in clause (h)) with respect to the Schedule 1 Included Services) will be such that the aggregate Monetary Cost of all Schedule 1 Included Services to be delivered over the 12-month
period following Closing to support the product flow contemplated by the Product Volume Forecast, using headcount assumptions consistent with the IT Headcount Forecast, (x) will not be less than 90% of the aggregate estimated cost of all
services reflected in the Estimated Cost Schedule, and (y) will not be greater than 110% of such aggregate estimated cost of all services reflected in the Estimated Cost Schedule. The Transition Services Agreement contains provisions regarding
certain price



152



---

adjustments for Schedule 1 Included Services in the event that (i) Purchaser revises the anticipated product volume which results in a change in forecast revenues (output of the monthly
Sales and Operations Plan) of 5% or more for any three-month period commencing 3 months from the approved monthly Sales and Operations Plan, or (ii) Purchaser revises the headcount of Active Employees and/or employees of Contract Service
Providers (as defined in the Transition Services Agreement), with the result that the Direct Cost of delivering IT Infrastructure Services and IT Applications Services included within Schedule 1 Included Services changes by more than 5% from the
aggregate cost of such IT Infrastructure Services and IT Applications Services reflected on the Estimated Cost Schedule. Notwithstanding anything to the contrary in this Agreement or in the Transition Services Agreement, it is understood and agreed
that the aggregate price to be paid by the Purchasers to the TSA Sellers for services under the Transition Services Agreement will be reduced by $10 million, the application of such reduction to be determined by the Purchaser subject to the consent
of the TSA Sellers (which consent will not be unreasonably withheld). For the avoidance of doubt, such reduction shall not apply to any services provided by the TSA EMEA Sellers pursuant to the Transition Services Agreement.

(d) The determination of the stipulated, monetary price of any Extra Services requested by the Purchaser will be determined in manner
analogous to the determination of Monetary Cost of Included Services, except that the price of such Extra Services will be the Direct Cost thereof as defined in the form of Transition Services Agreement in Exhibit P hereto (plus
any Special Third-Party Costs not reflected in such monetary price), with no further restriction.

(e) Until the Monetary Cost
of any service has been agreed and stipulated by the Parties or determined by arbitration in accordance with clause (h), the price of such service will be the Direct Cost thereof, as reasonably determined by the applicable TSA Sellers or TSA EMEA
Sellers under the Transition Services Agreement. Upon final determination of the Monetary Cost as contemplated herein, the parties will promptly reconcile any prior payments made by the Purchaser that were based on TSA Sellers or TSA EMEA
Sellers estimates of Direct Cost (with the applicable TSA Seller or TSA EMEA Seller paying to the Purchaser any amount by which such estimated amounts exceeded the proper amounts based on Monetary Cost as so finally determined, or with the
Purchaser paying to the applicable TSA Seller or TSA EMEA Seller any deficiency by which such estimated amounts were less than the proper amounts based on such Monetary Cost).

(f) Prior to the 45th day following the execution of this Agreement (Arbitration Trigger Date), each TSA Seller and TSA
EMEA Seller shall consult with each other and notify Purchaser of the name of the single person designated to serve on all such parties behalf as an arbitrator in case of any arbitration hereunder (except that the TSA EMEA Sellers may
designate a single person to serve as an arbitrator for all TSA EMEA Sellers, and the TSA Sellers may designate a different person to serve as an arbitrator for all Sellers), and the Purchaser shall notify each TSA Seller and TSA EMEA Seller of the
name of the person or, if the TSA Sellers and TSA EMEA Sellers have each appointed an arbitrator, the name of two persons designated to serve as Purchasers arbitrator(s) in case of any arbitration hereunder. If the TSA Sellers and TSA EMEA
Sellers have not designated their arbitrator or Purchaser has not designated its arbitrator(s) prior to the Arbitration Trigger Date (Non-Designating Party), and if thereafter such Non-Designating Party does not name an arbitrator
(and provide notice thereof



153



---

to the other applicable parties) within five Business Days after notice from any other Party requesting that such an arbitrator be named, then such Non-Designating Party shall lose the right to
appoint an arbitrator hereunder, and the arbitration shall be conducted exclusively by the arbitrator named by the other Party to the applicable arbitration.

(g) At any time after the Arbitration Trigger Date, any affected Party may submit any disagreements relating to the Included Services or the Extra Services, or the Monetary Cost of any Included Service or
the stipulated, monetary price of any Extra Service to binding arbitration for resolution, which arbitration proceeding will be initiated by notice delivered by such Party to the applicable counterparty. Such arbitration shall be conducted in
accordance with Section 5.36(h). The parties will use commercially reasonable efforts to resolve any disagreement as expeditiously as practicable.

(h) If any Party shall give notice of arbitration pursuant to Section 5.36(g), then, within ten days following initiation of such arbitration, the arbitrators theretofore designated by the applicable
parties to such arbitration shall jointly appoint a neutral arbitrator (the Neutral Arbitrator), who shall be unaffiliated with any Party (in the event such two arbitrators do not so jointly appoint a neutral arbitrator, then,
upon the request of any party to such arbitration, such neutral arbitrator, who must be unaffiliated with any Party, will be promptly appointed by the American Arbitration Association). Any arbitration hereunder shall be conducted by such three
arbitrators (except as provided in Section 5.36(f) or below in this Section 5.36(h)), and shall take place in New York City in accordance with the Commercial Arbitration Rules of the American Arbitration Association. If an arbitrator named
by a Party hereunder ceases to serve for any reason, then such Party shall name a successor arbitrator within five Business Days following notice from an adverse Party (Notifying Party) requesting that such a successor be named
(if a successor is not so named, then the arbitration will be conducted solely by the Neutral Arbitrator if theretofore appointed, and otherwise by the arbitrator named by the Notifying Party). The arbitrators will resolve the matters in dispute
within thirty (30) days following the selection of the Neutral Arbitrator; provided, however, that if any disagreement with respect to Included Services has not been resolved by the one hundred twentieth (120th) day after the date of this
Agreement (or if earlier the fifteenth (15th) day prior to the Closing Date), then at any time thereafter any Party to such arbitration may serve notice on the arbitrators demanding that the Neutral Arbitrator alone render a final decision
within 10 days following receipt of such notice (any decision by a majority of the arbitrators shall otherwise be deemed the decision of the arbitrators). The decision of a majority of the arbitrators, or of the Neutral Arbitrator alone, as
applicable, shall be in writing, shall be final and conclusive on the Parties, and counterpart copies thereof shall be delivered to all of the Parties. Judgment may be had on the decision of the arbitrators so rendered in any court of competent
jurisdiction. The Purchaser shall bear the fees and expenses of the arbitrator it designates, the applicable TSA Seller or TSA EMEA Seller shall bear the fees and expenses of the arbitrator it designates, and the Purchaser and the applicable TSA
Seller or TSA EMEA Seller shall equally share the fees and expenses of the Neutral Arbitrator. Notwithstanding anything to the contrary in this Agreement or in the Transition Services Agreement, if any arbitration hereunder to finalize the scope of
any Included Service has not been completed, and an arbitral decision rendered, by the second Business Day preceding the Closing Date, then (i) the applicable TSA Seller or TSA EMEA Seller shall provide such Service after Closing with the scope
advocated by the Purchaser (and the Purchaser will pay Direct Cost for such Services, as provided in the Transition Services Agreement and as



154



---

reasonably determined by the applicable TSA Seller or TSA EMEA Seller, until the Monetary Cost for such service is determined in accordance with the provisions of this Section 5.36 upon
which a reconciliation will occur as described in Section 5.36(e)), and (ii) such arbitration will terminate with respect to the scope of service as of such second Businesses Day preceding the Closing (with the arbitrators deemed to have
rendered a decision defining such scope as so advocated by the Purchaser). Nothing herein will affect any arbitration to the extent the subject matter thereof relates to (i) any Extra Service or (ii) the price, Monetary Cost or Direct Cost
of any service.

(i) Solely, for purposes of this Section 5.36, the term Parties shall also include the TSA
EMEA Sellers.

SECTION 5.37. Assistance for Proxy Agreement. From the date hereof, the Main Sellers shall use their
reasonable best efforts to assist the Purchaser to seek any Consent required in order to terminate the Proxy Agreement and allow the Purchaser to acquire and exercise control over NGS and its business effective as of the Closing Date without a proxy
arrangement. Such assistance shall include promptly notifying the U.S. Defense Security Service of the transactions contemplated hereby pursuant to the NISPOM and Proxy Agreement, agreeing to terminate the Proxy Agreement effective as of the Closing
Date and engaging in discussions with the U.S. Defense Security Service in preparation for that result, and providing all information requested by the U.S. Defense Security Service related to the transactions contemplated hereby. Notwithstanding the
foregoing, between the date hereof and the conclusion of the Auction, none of the Sellers or the Companies shall be required to take any action pursuant to this Section 5.37 that would irrevocably modify, cancel or amend the Proxy Agreement.

SECTION 5.38. Customer Contract Review and Selection.

(a) In accordance with applicable Law and subject to the provisions of the Clean Team Confidentiality Agreement and the Confidentiality
Agreement, within seven (7) days of the date hereof, the Sellers shall provide the Clean Team Members with (i) access to the electronic databases and centralized file cabinets at Sellers workplaces or other sites where the Customer
Contracts are maintained and/or stored (such databases and file cabinets, the Sellers Files), where centralized file cabinets shall mean that the Sellers use their reasonable best efforts to cause the file
cabinets containing the Sellers Files, to the extent reasonably practicable given existing resources and spaces at the relevant facilities, to be aggregated, organized and labeled in a single, localized filing room, which Sellers shall have
clearly identified prior to the arrival of Clean Team Members, at each applicable site, and (ii) training of one (1) day (initially, in a single session for the Clean Team Members, which training shall be accessible by videoconference
and/or teleconference) and additional training as shall be reasonably requested by Clean Team Members, including specific training as is reasonably necessary to review the Sellers Files at any particular site, such as (y) training on how
to access specific electronic databases at such site and (z) training on how to locate specific information within file cabinets at such site. Sellers shall also provide existing indices, maps, tables of contents or equivalent references for
the purpose of identifying hard copies of materials within any filing cabinets or similar storage units. The Purchaser shall provide sufficient computer equipment to enable the Clean Team Members to access such electronic databases, and such
computer equipment shall be



155



---

compatible with Sellers electronic databases, which the Parties shall engage in their reasonable best efforts to confirm with each other prior to a visit by Clean Team Members to any site.

(b) The relevant Sellers shall cause their personnel responsible for maintaining and operating the Customer Contract
databases, at the locations where the Customer Contracts are retained in hard or soft copy form, to reasonably assist the Clean Team Members to locate copies of the relevant Customer Contracts and such information about or related to the Customer
Contracts as the Clean Team Members may reasonably request. Furthermore, the relevant Sellers shall allow the Persons listed in Section 5.38(b)(i) of the Sellers Disclosure Schedule to perform searches on the electronic databases comprising the
Sellers Files and assist with the identification of documents within the Sellers Files, as reasonably requested by Clean Team Members. Subject to applicable Law and the provisions of the Clean Team Confidentiality Agreement and the
Confidentiality Agreement, the relevant Sellers shall also use their reasonable best efforts to cause (i) the Persons listed in Section 5.38(b)(ii) of the Sellers Disclosure Schedule to be available, and, if such Persons are not available,
the Purchaser will accept the designation of an alternative representative from the applicable geographical and functional area, who has comparable knowledge to the unavailable Person, and (ii) without exception, each of the individuals listed
in Section 5.38(b)(iii) of the Sellers Disclosure Schedule to be made available, and if any such Person can not be made available, then Purchaser shall have the right to select, in its reasonable discretion, a suitable replacement for such
unavailable Person; each of the Persons in (i) and (ii) to be made available, at times designated by the Sellers, for two or, at the option of the Sellers, more separate meetings covering, in the aggregate, all the regions, in each case
with Clean Team Members and to take place in person or by teleconference within ten (10) days from the date hereof, to answer reasonable questions from the Clean Team Members about the content of Customer Contracts, the status of the relevant
Sellers relationship with the counterparties to such Customer Contracts, the economic performance under such Customer Contracts and any material issues that have arisen under such Customer Contracts. Following such meeting(s), subject to
applicable Law and the provisions of the Clean Team Confidentiality Agreement and the Confidentiality Agreement, the relevant Sellers shall cause members of their relevant management personnel knowledgeable about issues related to Customer
Contracts, including without limitation, global accounts, services and major geographical regions of the Business to be available at reasonable times and upon reasonable notice to answer reasonable questions from the Clean Team Members about the
content of the Customer Contracts, the status of the relevant Sellers relationship with the counterparties to such Customer Contracts, the economic performance under such Customer Contracts and any material issues that have arisen under such
Customer Contracts.

(c) The Main Sellers shall use their reasonable best efforts to produce and place in the Clean Team Data
Room, as soon as practical and in any event within ten (10) days of the date hereof, all material documentation that forms part of the Customer Contracts in force as of the date hereof with customers of the Business whose customer contracts
with the Sellers generated more than $1,000,000 in aggregate revenues for the Business during calendar year 2008 (each Customer Contract with such customers, a Major 2008 Customer Contract).

(d) The Sellers shall use reasonable best efforts to produce and place in the Clean Team Data Room, as soon as practical and in any event
within fifteen (15) days of the date hereof, any additional Customer Contracts which, prior to the date hereof, have been identified in



156



---

the Sellers sales forecasting process that is maintained in the Ordinary Course and which the relevant Sellers, in the exercise of their reasonable judgment, believe may result in revenues
of the Business in either (i) 2009 or (ii) if the relevant Contract was or is entered into after January 1, 2009, the period beginning on the date of execution of such Contract and ending twelve (12) months from the date of such
Contract, of greater than $500,000 (each, a Major 2009 Customer Contract, and together with any Major 2008 Customer Contracts, the Major Customer Contracts).

(e) In accordance with applicable Law and subject to the provisions of the Clean Team Confidentiality Agreement and the Confidentiality
Agreement, the Purchaser shall use its reasonable best efforts to cause its representatives, with any and all reasonably requested assistance from the Sellers pursuant to Sections 5.38(a), 5.38(b), 5.38(c) and 5.38(d) to (i) promptly review the
Sellers Files and identify those Customer Contracts that it seeks to review, including, at the Purchasers sole option, employing appropriate professional third parties as Clean Team Members to expedite such review and (ii) work with
the Sellers to minimize the disruption to Sellers workplaces or other sites caused by the Clean Team Members visits and review, and to leave such sites in substantially the same condition as when the Clean Team Members first occupied
such sites.

(f) On or before the relevant Contract Designation Date, the Purchaser shall notify the Main Sellers in writing
of those 365 Customer Contracts and Non-365 Customer Contracts entered into prior to the date hereof which fail to meet the Pre-Signing Inclusion Criteria and the Purchaser elects not to have assigned by the relevant Seller to the Purchaser or a
Designated Purchaser at Closing (as adjusted to reflect the resolution of any objection by the Main Seller to such notification, the Rejected Pre-Signing Customer Contracts). Such written notice to the Main Sellers shall also
indicate which specific Pre-Signing Inclusion Criteria the relevant 365 Customer Contract or Non-365 Customer Contract, as applicable, fails to meet. If the Main Sellers disagree with such notice, the Main Sellers shall promptly notify the Purchaser
thereof and the Purchaser and the Main Sellers shall then negotiate in good faith to resolve such disagreement. If either (i) the Purchaser and the Main Sellers fail to resolve such disagreement within ten (10) Business Days from the
delivery of the notice to the Purchaser (or such shorter period as will end on the Business Day before the Closing Date), or (ii) the Main Sellers do not object to the notice received from the Purchaser, the Purchasers categorization of
such Pre-Signing Customer Contract shall be given effect, save in the case of manifest error.

(g) Not later than
(30) days from the date hereof, the Sellers shall prepare and deliver to the Purchaser a list (to be updated each fifteen (15) days thereafter) (the Non-Qualified Post-Signing Customer Contract List) of all the Customer
Contracts entered into after the date hereof that fail to meet the Post-Signing Inclusion Criteria (the Non-Qualified Post-Signing Customer Contracts) and a list (to be updated each fifteen (15) days thereafter) that
identifies all Major 2009 Customer Contracts entered into after the date hereof (whether they meet the Post-Signing Inclusion Criteria or not). The Sellers shall use reasonable best efforts to include the relevant Customer Contracts on the first
update of the applicable lists following the execution of such Customer Contracts, to the extent commercially practicable. If the Purchaser disagrees with the categorization of a Post-Signing Customer Contract as a Non-Qualified Post-Signing
Customer Contract or becomes aware of a Customer Contract omitted from such list, it shall promptly notify the Main Sellers thereof and, the Purchaser and the Main Sellers shall then



157



---

negotiate in good faith to resolve such disagreement or agree on the proper categorization of such omitted Post-Signing Customer Contract. If the Purchaser and the Main Sellers fail to resolve
such disagreement or agree on such categorization within ten (10) Business Days from the delivery of the notice to the Main Sellers (or such shorter period as will end on the relevant Contract Designation Date), then the Purchasers
categorization of such Post-Signing Customer Contract shall be given effect, save in the case of manifest error. On or prior to the relevant Contract Designation Date, the Purchaser shall notify the Main Sellers in writing whether the Purchaser
elects not to have a Non-Qualified Post-Signing Customer Contract assigned by the relevant Seller to the Purchaser or a Designated Purchaser at the Closing (any Customer Contract so designated by the Purchaser for rejection shall be deemed a
Rejected Post-Signing Customer Contract and shall not be assigned to the Purchaser or a Designated Purchaser at 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 that may be imposed upon or payable 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 or agent, as applicable, at the Closing or thereafter, as requested of or by the applicable Seller. Upon request from a Seller, the Purchaser shall provide to such Seller an
original receipt (or such other evidence as shall be reasonably satisfactory to such Seller) evidencing the payment of Transfer Taxes by the Purchaser to the applicable Tax Authority under this Section 6.1. For the avoidance of doubt, Purchaser
shall remain liable in respect of any Transfer Taxes regardless of the date that the Assets are removed from the premises of a Seller or any Sellers supplier. All other Closing expenses will be paid by the Party incurring such expenses.

(b) 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, 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 reasonable efforts to cooperate to the extent necessary to obtain any such exemption or reduction. If the Purchaser or



158

any Designated Purchaser pays any Transfer Taxes pursuant to this Section 6.1 and a Seller thereafter becomes entitled to an actual cash refund for, or an actual reduction in Liability for,
Transfer Taxes payable by such Seller in respect of such Transfer Taxes paid by the Purchaser or a Designated Purchaser pursuant to this Section 6.1, then such Seller shall reimburse the Purchaser or Designated Purchaser for an amount equal to
such refund or actual reduction (net of reasonable costs and expenses incurred in obtaining such refund or reduction).

(c)
The applicable Seller(s) and Purchaser (or relevant Designated Purchaser) will, on or before the Closing, jointly prepare and execute an election, in the prescribed form and containing the prescribed information, to have subsection 167(1) of the
Excise Tax Act (Canada) apply to the sale and purchase of the Assets which would otherwise be subject to GST so that no GST is payable in respect of such sale and purchase under Part IX of the Excise Tax Act (Canada). 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 registration number is 119409258RT0001 (in the case of NNL) and 118802974RT0001 (in the case of Nortel

plus any interest and/or penalties payable as a consequence thereof.

SECTION 6.2. Withholding Taxes. Subject to
Section 2.4, the Purchaser and the Designated Purchasers shall be entitled to deduct and withhold from the Purchase Price, and the Purchaser shall be entitled to deduct and withhold from the Reverse Termination Fee, such amounts as the
Purchaser or Designated Purchasers, as the case may be, are required to deduct and withhold under the Code or any provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent such amounts are so withheld by
the Purchaser or a Designated Purchaser, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement and the Ancillary Agreements as having been paid to the relevant Seller in respect of whom such deduction and
withholding was made by such Purchaser or Designated Purchaser. None of the Parties is aware of any obligation to deduct and withhold any amounts from the Purchase Price or the Reverse Termination Fee under the Code, or any provision of state, local
or foreign Tax 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 reasonable efforts to cooperate in good faith to minimize the
amounts that the Purchaser or Designated Purchasers, as the case may be, are required to deduct and withhold.

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 all Taxes of any kind relating to the Assets or the conduct
or operation of the Business (including Taxes in respect of the income, business, property or operations of the Companies) for all Tax periods or portions thereof ending on or before the Closing Date 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 Business (including Taxes in respect of the income, business, property or operations of the Companies) 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 any Taxes based on or measured by income or receipts of the Business (including the business and operations of the Companies)
shall be allocated between the Pre-Closing Taxable Period and the Post-Closing Taxable Period on a closing-of-the-books basis. The amount of other Taxes shall be allocated between the Pre-Closing Taxable Period and the Post-Closing Taxable Period in
the following manner: (i) in the case of a Tax imposed in respect of property (excluding, for the avoidance of doubt, any income Tax) and that applies ratably to a Straddle Period, 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 sales, value-added and similar transaction-based Taxes (other than Transfer Taxes allocated under Section 6.1), such Taxes shall be allocated to the portion of the Straddle Period in which the
relevant transaction occurred.

SECTION 6.5. Section 338 Election. Upon the written request of the Purchaser, in
its sole and exclusive discretion, (x) the Sellers and the Purchaser or, as applicable, any Designated Purchaser shall join in making elections under Code section 338(h)(10) (and any corresponding election under state, local, or foreign law) (a
Section 338(h)(10) Election) with respect to the Purchasers (or any Designated Purchasers) purchase of the Shares of the Companies pursuant to this Agreement, or (y) the Sellers shall make or cause to be made such
stock basis reduction elections under Treas. Reg. Section 1.1502-36(d)(6)(i)(A) (Loss Duplication Elections) as are necessary to reduce as far as possible the potential for loss duplication. The Purchaser shall indemnify the
Sellers for any actual Tax Liability that (i) arises during the taxable year that includes the Closing Date or the two (2) taxable years immediately following and (ii) would not have arisen but for a Section 338(h)(10) Election
or a Loss Duplication Election made pursuant to this Section 6.5; provided, however, that the Purchaser shall have no obligation to indemnify the Sellers for any Tax Liabilities pursuant to this Section 6.5 with respect to which the

(a) Notwithstanding the provisions of Section 5.24, but subject to the provisions of Section 5.6, (i) after the Closing Date,
the Purchaser, the Designated Purchasers and the Companies, 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 information, records or documents relating to
liability for Taxes with respect to the Assets, the Assumed Liabilities, the Business or the Companies for all periods prior to or including the Closing Date (including Straddle Periods), and will preserve such information, 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 in the possession of a second party relating to any of the Assets, the Assumed Liabilities, the
Business or the Companies 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 not injurious to the second party,
the second party will allow representatives of the other party access to such records during regular business hours at the second partys place of business for the sole purpose of obtaining information for use as aforesaid and will permit such
other party to make extracts and copies thereof as may be necessary or convenient. The obligation to cooperate pursuant to this Section 6.6 shall terminate at the time the relevant applicable statute of limitations expires (giving effect to any
extension thereof).

(b) On or prior to Closing, the Sellers shall cause copies of Restricted Technical Records to be placed
into escrow with the Records Custodian, who shall hold such Restricted Technical Records for ten (10) years in accordance with an escrow agreement between the Purchaser, the Sellers and the Records Custodian, in form satisfactory to the
Purchaser and the Seller. 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) of the
scientific research and experimental development Tax credits of the Sellers under the Income Tax Act (Canada), and only if such advisors have executed an appropriate confidentiality agreement in form satisfactory to the Purchaser. 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).

(c) 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 such advisors have executed an appropriate confidentiality agreement satisfactory to the Purchaser.

(d) 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



161



---

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).

(e) On or prior to Closing, the Sellers shall use their reasonable best efforts to calculate and provide to the Purchaser (with expenses reasonably allocable to such calculations split evenly between the Sellers, on the one hand, and the
Purchaser, on the other hand) 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, 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 within 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.

SECTION 6.7. 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

kind (including opinions or other Tax analyses) that are provided to the taxpayer 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 6.8. 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, the Business or the Companies, for all Pre-Closing Taxable Periods (other than any Tax Returns with respect to Transfer Taxes
(Transfer Tax Returns) described below in Section 6.8(b)). 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) Sellers as and when required by Law. In every case permitted by Law, the Sellers shall elect to treat the Closing Date as the close of a taxable period, so as to minimize the
number of Straddle Period Tax Returns and Straddle Periods.

Agreement and the transactions contemplated hereunder or in respect of the execution of any other Transaction Document shall be prepared by the Party that customarily has primary responsibility for filing such Transfer Tax Return pursuant to the

respects and shall be prepared on a basis consistent with Tax Returns prepared for prior taxable periods unless a different treatment of any item is required by an intervening change in Law or this Transaction. 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, except for such Taxes that are the responsibility of the Sellers pursuant to this Article VI; such Taxes
shall be paid to the Purchaser or a Designated Purchaser no later than ten (10) Business Days prior to the due date for the applicable Straddle Period Tax Return.

Companies 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 sixty (60) days before the date such Tax Return is required to be filed with the
relevant Tax Authority (provided, however, that if the information necessary to prepare a draft of any such Tax Return is not available to the Purchaser at least ninety (90) days before the date such Tax Return is required to be filed
with the relevant Tax Authority, then the timeframe set forth in Section 6.8(e) shall apply). The Main Sellers shall have fifteen (15) days after the date of receipt thereof to submit to the Purchaser, in writing, the Main Sellers

binding upon the Parties, and the Purchaser shall file such Tax Return 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.

(e) If the information necessary to prepare a draft of any Tax
Return for a Straddle Period (other than a Transfer Tax Return described in Section 6.8(b)) is not available to the Purchaser at least ninety (90) days before the date such Tax Return is required to be filed with the relevant Tax

ARTICLE VII

EMPLOYMENT MATTERS

SECTION 7.1. Employment Obligations with Respect to Non-Union Employees. Except as provided in the first sentence of Section 7.1.1, the first sentence of Section 7.1.2(c)(ii) and except
as the schedules referenced in Section 7.1.2(e) may apply to Union Employees, the provisions of this Section 7.1 shall apply to Non-Union Employees.

7.1.1. Employment Terms. Purchaser hereby agrees to offer employment to that aggregate number of Employees (other than Share Transfer Employees) set forth in Section 7.1.1 of the Sellers
Disclosure Schedule (which Section 7.1.1 of the Sellers Disclosure Schedule shall separately identify that number of Employees (including Union Employees in Canada) to be offered employment in each of Canada, China/Hong Kong/Taiwan, and the
United States, and the aggregate number of Employees to be offered employment in each of the Remaining APAC Countries and the Remaining CALA Countries). Within thirty (30) days following the date hereof, the Purchaser shall identify the minimum
aggregate number of employees in Australia/Japan to whom the Purchaser shall make an offer of employment, provided that, promptly after the date hereof, the relevant Sellers have permitted the Purchaser access to such information as the Purchaser
reasonably requires in accordance with Sections 5.6(a) and 7.4(d) in order to make such identifications (except as prohibited by Law). Within one hundred and five (105) days following the date hereof, the Purchaser shall notify the Sellers of
the identity of the Employees (other than Share Transfer Employees or other Employees whose employment transfers automatically by operation of Law to the Purchaser or a Designated Purchaser) the Purchaser and/or the Designated Purchasers intend to
hire as of the Closing Date. Promptly following the latest of the granting of the U.S. Sale Order and the Canadian Approval and Vesting Order and receipt of Regulatory Approvals, the Purchaser shall, or shall cause a Designated Purchaser to, extend
a written offer of employment in a manner that provides no less than a two-week Employee consideration period (Offer Consideration Period), in a form agreed by the Primary Parties and in compliance with applicable Law, to those
Employees identified by Purchaser in accordance with the immediately preceding sentence, with such employment to take effect under the terms stated herein as of the Effective Hire Date, as defined below. Such offers shall, except to the extent
otherwise required by Law, be for employment on terms and conditions that are substantially comparable to those terms and conditions of employment of similarly situated employees of the Purchaser or a Designated Purchaser, as applicable, and,
without limiting the generality of the foregoing, shall include (i) an annual base salary for each such Employee that is equal to the annual base salary for such Employee as set out in the Employee Information, (ii) employment in a
reasonably comparable position as set out for the Employee in the Employee Information, (iii) a location reasonably contiguous to their



165



---

current location as set out in the Employee Information and (iv) other terms and conditions of employment as set forth in this Section 7.1. Purchaser shall provide in its offers of
employment that the Employees acceptance of such offer will be deemed to be a consent to the transfer of his particular Employee Record. Share Transfer Employees and 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 in the sentence before the preceding sentence. For purposes of this Agreement, to the extent certain terms and conditions of employment are required to be maintained
under applicable Law or Seller Employee Plans in order to avoid Sellers incurring severance or other employment termination obligations or Liability under the WARN Act with respect to Employees at any time after the Closing Date such terms and
conditions shall be deemed to be required by applicable Law. Seller shall provide to the Purchaser such available and relevant information, and Seller and Purchaser shall cooperate in good faith, so as to enable Purchaser to comply with its
undertakings under this Section 7.1.1. Employees employment with Purchaser or a Designated Purchaser or, with respect to Share Transfer Employees or other Employees whose employment transfers by operation of Law, continued employment
after the Employee Transfer Date, shall not include a probationary period and shall not be conditioned upon such employees satisfactorily completing a background investigation, drug test or other employment screening processes unless such screening
process is required by applicable Law, a relevant Purchaser contract, or other customer requirement; provided, however, the Purchaser or Designated Purchaser may require Employees to provide evidence that they are legally permitted to be employed by
the Purchaser or a Designated Purchaser, as required by applicable Law. Purchaser shall notify the Main Sellers of the acceptance and rejections of offers of employment that have been received from each of the Employees (x) on at least a weekly
basis during the Offer Consideration Period and (y) in total within three (3) Business Days following the end of the Offer Consideration Period. Any Employee who accepts such offer of employment and commences employment with Purchaser or a
Designated Purchaser, as applicable, pursuant to this Agreement, and any Employees whose employment transfers by operation of Law and Share Transfer Employees, 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 Business Day immediately following the date the Inactive Employee is released to return to active employment in accordance with Sellers leave policies and on which
such Inactive Employee reports to work with the Purchaser or a Designated Purchaser. 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 visas or permits
as are required for it to employ Employees with visas or permits as indicated in the Employee Information. Visa Employees and Other Loaned Employees shall remain employed by the relevant Seller under the terms and conditions of the Loaned Employee
Agreement. The Effective Hire Date for Non-Union Employees is (a) the Employee Transfer Date for those Employees other than Inactive Employees, Visa Employees and Other Loaned Employees, (b) 12:01 a.m. on the first 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 and (c) the date specified in the Loaned Employee Agreement with
respect to Visa Employees and Other Loaned Employees.

7.1.2. Employee Benefits.



166



---

(a) The Purchaser or a Designated Purchaser shall, and shall cause its relevant Affiliates
to, recognize the service date of each Transferred Employee as set out in the Employee Information, to the same extent that service credit would be given under the analogous Seller Employee Plan, for purposes of eligibility and vesting, and with
respect to any severance or vacation plan, the determination of levels of benefits, but not for purposes of benefit accrual, or otherwise for determination of the amount or duration of benefits under any Purchaser Employee Plans, except
(i) with respect to Transferred Employee Plans, or (ii) as otherwise required by applicable Law.

(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 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.

(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 twelve (12) months from the Closing Date, the Purchaser shall, or shall cause its relevant Affiliates to, provide
Transferred Employees with the same severance payments and benefits as similarly situated employees of Purchaser or a Designated Purchaser.

(ii) The Sellers shall pay the amount of compensation with respect to such accrued and unused vacation days that are due and owing to the Transferred Employees, including the Union Employees, (other than
Transferred Employees who are (x) Share Transfer Employees, whose accrued vacation is specified in Section 7.1.2(c)(ii)(A) of the Sellers Disclosure Schedule, and (y) those Transferred Employees whose accrued vacation is specified in
Section 7.1.2(c)(ii)(B) of the Sellers Disclosure Schedule), as of their Effective Hire Date, to such Transferred Employees at or as soon as reasonably practicable following their Effective Hire Date, or such earlier time as may be required by
Law. The Purchaser will, and will cause the relevant Designated Purchasers to, make reasonable best efforts to accommodate time off requests of such Transferred Employees until such time as they accrue sufficient paid time off under the Purchaser
Employee Plans to address their vacation plans.

(iii) Section 7.1.2(c)(ii)(A) of the Sellers Disclosure
Schedule sets forth the amount of accrued and unused vacation days that are due and owing to the Share Transfer Employees as of the date hereof and such amount shall be updated by the Sellers as of each Share Transfer Employees Effective Hire
Date. Section 7.1.2(c)(ii)(B) of the Sellers Disclosure Schedule sets forth the amount of accrued and unused vacation days that are due and owing to certain Transferred Employees as of the date hereof, and such amount shall be updated by the
Sellers in respect of such Employees and to include all Loaned Employees as of the Closing Date. The Purchaser shall, or shall cause its relevant Affiliates to, grant each Share Transfer Employee and each such Transferred Employee (other than



167



---

those Loaned Employees whose accrued and unused vacation days are cashed out by Sellers or their Affiliates in connection with the termination of employment with Sellers or their Affiliates) paid
time off in an amount equal to such accrued unused vacation days set forth for such Share Transfer Employee or such Transferred Employee in the applicable Section of the Sellers Disclosure Schedule. If such Share Transfer Employee or such
Transferred Employee terminates employment with the Purchaser or an Affiliate of 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; provided that the Purchaser shall only be required to make such payment if such Transferred Employees employment terminates prior to the date which is twelve (12) months following the Closing Date, unless
otherwise required by applicable Law. Each Transferred Employee listed on Section 2.2.8 of the Sellers Disclosure Schedule who has pre-Closing accrued vacation that remains unused or unpaid after the Accrued Vacation Amount Final Payment Date
shall be subject to the provisions of this Section 7.1.2(c)(iii) in respect of any such pre-Closing accrued vacation that is not otherwise paid to such Transferred Employee except where payment of accrued amounts instead of carryover is
required under applicable Law, in which case the Purchaser shall make such payments to the applicable Transferred Employee.

(iv) Under the vacation policy of the Purchaser or an Affiliate of the Purchaser, 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 Share Transfer Employees and to Transferred Employees whose accrued vacation is specified in Section 7.1.2(c)(ii)(B) of the Sellers Disclosure Schedule (other than those Loaned Employees whose accrued and unused
vacation days are cashed out by Sellers or their Affiliates in connection with the termination of employment with Sellers or their Affiliates) shall not be decreased prior to the date which is twelve (12) months following the Closing Date by
the Purchaser or its Affiliates as a result of the obligation in Section 7.1.2(c)(iii) 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. Notwithstanding the foregoing, Share Transfer Employees and such Transferred Employees shall have only through and until the date which is twelve (12) months following the Closing Date during which to use accrued and unused vacation days
due and owing as of the Effective Hire Date. Any such accrued vacation days that remain unused at such time shall be automatically forfeited.

(v) The Purchaser or Designated Purchaser shall provide each Transferred Employee employed in India with the benefit of the amount set forth on Section 7.1.2(c)(v) of the Sellers Disclosure Schedule
of gratuity payment, at such time, if any, as such payment thereof is due and owing to each such Transferred Employee under applicable Law, taking into account in the



168



---

calculation of such payment the service of such Transferred Employee as set forth in the Employee Information and such Transferred Employees service with Purchaser on and after the Closing
Date. 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)(v) 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 Purchaser on and after the Closing Date. Section 7.1.2(c)(v) of the Sellers Disclosure Schedule shall be updated no later than ten (10) Business Days prior to 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.

(vi) For purposes of clarification, the Parties agree that Inactive Employees who become
Transferred Employees before the date when the Main Sellers and the EMEA Sellers deliver to the Purchaser pursuant to 2.2.3.1(a) the Closing Statement including the calculation of the Closing Accrued Vacation Amount will be considered Transferred
Employees for purposes of determining the Closing Accrued Vacation Amount or any other provisions that adjust the Purchase Price in respect of Transferred Employees vacation or, if applicable, gratuity pay in respect of Transferred Employees
located in India and sick leave and long service leave in respect of Transferred Employees located in Australia. For the avoidance of doubt, Inactive Employees as of the Closing Date will be listed on Section 2.2.8 of the Sellers Disclosure
Schedule, Section 7.1.2(c)(ii)(B) of the Sellers Disclosure Schedule and Section 7.1.2(c)(v) of the Sellers Disclosure Schedule, as applicable, but will not be treated as Transferred Employees for purposes of determining the Accrued
Cash-Out Vacation Escrow Amount or, if they have not become Transferred Employees before the date when the Main Sellers and the EMEA Sellers deliver to the Purchaser pursuant to Section 2.2.3.1(a) the Closing Statement including the calculation
of the Closing Accrued Vacation Amount, the Accrued Vacation Amount. The Parties further agree that Seller shall pay to Inactive Employees who become Transferred Employees on or after the date when the Main Sellers and the EMEA Sellers deliver to
the Purchaser pursuant to Section 2.2.3.1(a) the Closing Statement including the calculation of the Closing Accrued Vacation Amount all accrued and unused vacation and, if applicable, gratuity pay with respect to such Transferred Employees
located in India and long service leave and sick leave with respect to such Transferred Employees located in Australia through the date of employment termination with Seller, unless the Parties otherwise agree in writing at or after the Closing with
respect to any such Inactive Employees in India or Australia who become Transferred Employees.

(d) Except with respect to
Share Transfer Employees or any Employee whose benefits are specified by applicable Law, each Transferred Employee (and their eligible



169



---

dependents, as applicable), shall 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, which apply to employees of the Purchaser or a Designated Purchaser in the country where such Transferred Employee is employed as of the relevant Effective Hire Date and at a cost to such Transferred Employee, which is
substantially comparable to the costs of those parallel benefit plans of similarly situated employees of the Purchaser. 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 such 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,
provided that such employee provides an explanation of benefits or similar documentation of such expenses paid or incurred to the Purchaser or its Affiliates. With respect to Transferred Employees who are Share Transfer Employees, the above
provisions shall apply to any Purchaser Employee Plan that the Purchaser offers to such Transferred Employees but not with respect to any Transferred Employee Plans. Nothing in this paragraph or otherwise in this Article 7 shall be construed as
constituting an amendment of any employee benefit plan.

(e) The Parties agree to comply with provisions set forth in
Section 7.1.2(e) of the Sellers Disclosure Schedule, relating to Canadian Pension Plans.

(f) Neither Section 7.1.1
nor this Section 7.1.2 restricts the right of the Purchaser to terminate the employment of any Transferred Employee after the Closing, provided any such termination is effected in accordance with applicable Law, the terms of any applicable
Purchaser Employee Plan or Transferred Employee Plan 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. 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.

SECTION 7.3. Excluded Employee Liabilities. For purposes of clarity, except as otherwise provided in the Loaned
Employee Agreement, the Sellers shall retain, and neither the Purchaser nor any of the Designated Purchasers shall assume at the Closing, any of the following Liabilities of the Sellers (the Excluded Employee Liabilities):

(a) except with respect to any Share Transfer Employees of the NGS Companies and/or their qualified beneficiaries, any
obligation to provide continuation coverage pursuant to COBRA 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 prior to such Employees Effective Hire Date;



170



---

(b) any Liabilities resulting from any Action (i) by any Employee (other than a Share
Transfer Employee or another Employee whose employment transfers to the Purchaser or a Designated Purchaser by operation of Law) relating to his/her employment or termination of employment with any of the Sellers, or (ii) an applicant with
respect to potential employment with any of the Sellers in the Business;

(c) any Liabilities under the WARN Act which arise
out of or result from any layoff, termination of employment or the closing or relocation of worksites or the like by the Sellers on or before the Closing Date other than Liabilities related to the Transferred Employees as a result of the actions or
inactions of the Purchaser as provided in Section 2.1.3(e)(ii) and (iv) or as provided in Section 2.1.3(e)(iii);

(d) other than with respect to the Companies and the Share Transfer Employees, any Liabilities for Employees and independent contractors related to the Business that are not Transferred Employees; and

(e) other than with respect to the Companies and the Share Transfer Employees, any other Liabilities relating to Employees, independent
contractors or Seller Employee Benefit Plans that are not expressly assumed under this Agreement.

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 prior to the Employee Transfer Date;

(ii) the Employee Information shall not be disclosed to any other Person (including, for the avoidance of doubt, any other
employee of the Purchaser or any Designated Purchaser or other Affiliate of the Purchaser)



171



---

without the consent of the Main Sellers, such consent not to be unreasonably withheld;

(iii) 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

(iv) 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 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, provided that from and after the date on which the Purchaser determines its final list of Employees to whom offers shall be made under Section 7.1.1, Sellers shall
provide updated Employee Information only with respect to such Employees, and shall provide the Purchaser with the final updated Employee Information with respect to those Employees to whom the Purchaser has made offers of employment under
Section 7.1.1 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 a Transferred 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.

(d) The Purchaser and the Sellers shall cooperate with each other in connection with the process by which Employees are designated to become
or not become Transferred Employees, and otherwise 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. Without limiting the generality of the foregoing, within 105 days following the date hereof, the Sellers agree to commence discussions with the Purchaser regarding the
identity of the Employees who will be offered employment under Section 7.1.1, and promptly after the date hereof, as permitted by applicable Law, provide the Purchaser reasonable access to books, records, personnel files, or other documentation
as provided in Section 5.6(a). For the avoidance of doubt, for purposes of Section 5.6(a), the Sellers agree to use reasonable best efforts to obtain any consent of employees necessary to provide the Purchaser with such access.

(e) 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 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(e) shall prevent the Sellers from
conducting generalized employment searches, including placing bona fide public advertisements, that are not specifically



172



---

targeted at such Transferred Employees. During the Non-Solicitation Period, 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 (ii) any Employees who have rejected the employment offer of 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 Purchaser or a Designated Purchaser did not make an offer pursuant to Section 7.1.1; provided, however,
that nothing in this Section 7.4(e) shall prevent 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 Designated Sellers.

(f) As of the Effective Hire Date, the Sellers shall release any non-competition
or confidentiality obligations in respect of the 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 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.

(g) 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 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.

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

(i) In respect of the employees employed by NN International and providing services in Saudi Arabia, as set forth on Section 7.4(i) of the Sellers Disclosure Schedule: (i) the Main Sellers shall
cause NN International, from the date hereof, to comply with the provisions of Paragraphs 6.1, 6.3 and 6.5 (to the extent applicable) and 8.1 through 8.3 of Schedule 6 to the EMEA Asset Sale Agreement as if NN International were a Relevant EMEA
Seller thereunder and Clauses 10.21.7(D), (E), (G) or (J) of the EMEA Asset Sale Agreement as if NN International were an EMEA Seller in respect of those clauses; (ii) NN International shall comply with all of the relevant terms of
Schedule 6 to the EMEA Asset Sale Agreement as if it were a Relevant EMEA Seller under the EMEA Asset Sale Agreement and Clauses 10.21.7(D), (E), (G) or (J) of the EMEA Asset Sale Agreement as if it was an EMEA Seller in respect of those
clauses; and (iii) the Purchaser shall, or shall procure that the relevant EMEA Designated Purchaser shall, comply from the date hereof with its relevant obligations to NN International as



173



---

if NN International were a Relevant EMEA Seller for the purposes of Schedule 6 of the EMEA Asset Sale Agreement. In addition, employees of NN International performing services in Saudi Arabia in
respect of the Business shall be treated as based in Saudi Arabia for purposes of Schedule 6 to the EMEA Asset Sale Agreement and, for the avoidance of doubt, any such employees who are selected by the Purchaser or relevant EMEA Designated Purchaser
pursuant to Paragraph 1.1.12 of Schedule 6 to the EMEA Asset Sale Agreement shall be deemed to be Non-ARD Transferring Employees (as defined in the EMEA Asset Sale Agreement) for the purposes of the EMEA Asset Sale Agreement. For the avoidance of
doubt, the employees listed in Section 7.4(i) of the Sellers Disclosure Schedule are not deemed to be Employees or Transferred Employees for the purposes of this Agreement.

SECTION 7.5. No Amendment of Plans. Notwithstanding anything in the Agreement to the contrary, no provision of this Agreement is
intended to, or does, constitute the establishment or adoption of, or amendment to, any employee benefit plan (within the meaning of Section 3(3) of, or subject to, ERISA), and no person participating in any such employee benefit plan
maintained by either the Seller or the Purchaser or the Designated Purchaser, shall have any claim or cause of action, under ERISA or otherwise, in respect of any provision of this Agreement as it relates to any such employee benefit plan or
otherwise.

of an Intentional Breach by the EMEA Sellers of the EMEA Asset Sale Agreement) of the EMEA Asset Sale Agreement), (ii) when this Agreement is terminated, the Purchaser is not in breach of this Agreement or the EMEA Asset Sale Agreement as a
result of an Intentional Breach which Intentional Breach would result in a failure to satisfy the conditions to Closing set forth in Section 8.1 and/or Section 8.2, as applicable, and, in each case, which, if capable of being cured, has
not been cured within the applicable Breach Cure Period, and (iii) an Alternative Transaction is entered into before, on or within nine (9) months following such termination and is eventually consummated, the Sellers and the EMEA Debtors
shall pay to the Purchaser in immediately available funds, within five (5) Business Days of the consummation of such Alternative Transaction, an aggregate cash fee equal to (x) $14,250,000 (the Break-Up Fee), minus

(b) In the event that (i) (A) this Agreement is terminated pursuant to any
provision in Section 9.1 (other than Section 9.1(a), Section 9.1(b)(iv) (as a result of a termination of the EMEA Asset Sale Agreement pursuant to Clause 15.4.1, Clause 15.4.2(G), Clause 15.4.3, or Clause 15.4.9 of the EMEA Asset Sale
Agreement), Section 9.1(b)(vii), Section 9.1(c)(ii), Section 9.1(d) or Section 9.1(i)), or (B) this Agreement is terminated pursuant to any provision in Section 9.1 and, prior to such termination, the Sellers publicly
announce (1) the retention of the Business by all or some of the Sellers (or their successor entities) under a stand-alone plan of reorganization approved by the U.S. Bankruptcy Court or any plan of arrangement approved by the Canadian Court,
or (2) that any portion of the Business or the Assets and the EMEA Assets will be sold, transferred or otherwise disposed, directly or indirectly, in connection with the closure, liquidation or winding up of the Business or any of the Sellers,
the EMEA Sellers or the Companies (except for any sale to the Purchaser or a Designated Purchaser contemplated by the Transaction Documents), and (ii) when this Agreement is terminated, the Purchaser is not in breach of this Agreement or the
EMEA Asset Sale Agreement as a result of an Intentional Breach which breach would result in a failure to satisfy any of the conditions to Closing set forth in Section 8.1 and/or Section 8.2 or Clause 15.1 and/or Clause 15.2 of the EMEA
Asset Sale Agreement, as applicable, and, in each case, which, if capable of being cured, has not been cured within the applicable Breach Cure Period, the Sellers and the EMEA Sellers shall pay the Purchaser an aggregate amount in cash equal to the
total amount of all reasonable and documented fees, costs and expenses incurred by the Purchaser in connection with the preparation, execution and performance of this Agreement and the transactions contemplated hereby, including all filing and
notification fees, and all fees and expenses of the Purchasers representatives (the Expense Reimbursement); provided, however, that the Expense Reimbursement shall not be payable in the event that the Agreement
is terminated pursuant to Section 9.1(b)(vi) if at the time of such termination (i) the condition set forth in Section 8.1(a) is not satisfied and (ii) the conditions set forth in Section 8.1(b), Section 8.1(d),
Section 8.3(a), Section 8.3(b), Section 8.3(d) and Section 8.3(e) are satisfied other than any failure to satisfy any such condition listed in clause (ii) that is caused by the failure to obtain any Antitrust Approval or an
Intentional Breach by Purchaser of this Agreement which, if capable of being cured, has not been cured within the applicable Breach Cure Period. Notwithstanding the foregoing, the Expense Reimbursement shall not exceed $9,500,000 in the aggregate
(the Expense Reimbursement Limit). If the Expense Reimbursement does not exceed the Expense Reimbursement Limit, the Sellers and the EMEA Sellers agree that the Expense Reimbursement is a reasonable amount given the size and
complexity of the transactions contemplated by this Agreement and the EMEA Asset Sale Agreement. The Expense Reimbursement shall be paid by wire transfer or other means reasonably acceptable to the Purchaser not later than five (5) Business
Days following the receipt by the Main Sellers and NNUK of written notice from the Purchaser describing the fees and expenses that constitute the Expense Reimbursement in reasonable detail.

(c) The Sellers shall pay two-thirds (2/3) and the EMEA Debtors shall pay one-third (1/3) of each of the Break-Up Fee and the
Expense Reimbursement if payable hereunder. The Sellers and the EMEA Debtors obligations to pay their respective shares of the Break-Up Fee and the Expense Reimbursement pursuant to this Section 9.2 shall be several and not joint
(but the obligation of the Sellers to pay two-thirds (2/3) of each of the Break-Up Fee and Expense Reimbursement shall be joint and several among the Sellers and the obligation of



181



---

the EMEA Debtors to pay one-third (1/3) of each of the Break-Up Fee and Expense Reimbursement shall be joint and several among the EMEA Debtors) and shall survive termination of this
Agreement or the EMEA Asset Sale Agreement and shall (i) to the extent owed by the U.S. Debtors constitute an administrative expense of the U.S. Debtors under sections 503(b) of the U.S. Bankruptcy Code and (ii) to the extent owed by the
EMEA Debtors, constitute an expense of the administration under Paragraph 99 of Schedule B1 to the Insolvency Act 1986 and/ or Rule 2.67 of the Insolvency Rules 1986; provided, however, in the event that any Seller or any EMEA Seller
or any Affiliate of any Seller or EMEA Seller agrees to pay a break-up fee or expense reimbursement to any subsequent purchaser of assets or shares, with an unadjusted, aggregate purchase price greater than or equal to $100,000,000 and such break-up
fee or expense reimbursement has priority over any administrative expenses specified in section 503(b) or 507(b) of the U.S. Bankruptcy Code, then the portion of the Break-Up Fee and Expense Reimbursement payable to the Purchaser or its Affiliates
by the Sellers shall have administrative expense status under section 364(c) of the U.S. Bankruptcy Code with priority over any and all administrative expenses specified in section 503(b) or 507(b) of the U.S. Bankruptcy Code (to the extent such
concept is applicable to such Sellers).

(d) Notwithstanding anything to the contrary herein, the Sellers obligation to
pay the Break-Up Fee and/or Expense Reimbursement pursuant to this Section 9.2 is expressly subject to entry of the U.S. Bidding Procedures Order and Canadian Sales Process Order.

SECTION 9.3. Reverse Termination Fee.

(a) The Purchaser shall pay to the Distribution Agent (as agent for the Sellers and the EMEA Sellers) a cash fee in an aggregate amount equal to $100 million (such aggregate cash fee, the Reverse
Termination Fee) in the event that:

(i) this Agreement is terminated by Purchaser pursuant to
Section 9.1(i); or

(ii) (A) at the time of termination of the Agreement, (1) the conditions set
forth in Section 8.1(a) have not been satisfied because of the failure to obtain any Antitrust Approval and/or (2) the Purchaser is in breach in any material respect of its representations, warranties, agreements or covenants set forth in
this Agreement or the EMEA Asset Sale Agreement as a result of an Intentional Breach which breach (x) would result in a failure to satisfy any of the conditions to Closing set forth in Section 8.1 and/or Section 8.2, as applicable, or
the conditions to Closing (as defined in the EMEA Asset Sale Agreement) set forth in Clause 15.1 and/or Clause 15.2 of the EMEA Asset Sale Agreement, as applicable, and (y) if capable of being cured, such breach by the Purchaser is not cured
within the applicable Breach Cure Period (such breach, a Material Intentional Purchaser Breach); and

(B)(1)
this Agreement is terminated by the Main Sellers pursuant to Section 9.1(c)(ii) or Section 9.1(d) hereof, (2) the EMEA Asset Sale Agreement is terminated by the Joint Administrators pursuant to Clause 15.4.3 thereof, or (3) this
Agreement is terminated by either Primary Party pursuant to



182

Section 9.1(b)(vi) or Section 9.1(b)(vii) hereof or the EMEA Asset Sale Agreement is terminated by the Joint Administrator or the Purchaser pursuant to Clause 15.4.2(F) or Clause
15.4.2(G) thereof;

provided, however, that notwithstanding the foregoing, the Reverse Termination Fee shall not
be payable pursuant to this clause (ii) if at the time of termination:

(x) (1) the Sellers are in
breach of this Agreement in any material respect as a result of an Intentional Breach, which breach would result in a failure of the conditions to Closing set forth in Section 8.1 or Section 8.3 to be satisfied, and in each case, which, if
capable of being cured, is not cured within the applicable Breach Cure Period or (2) the EMEA Sellers are in breach of the EMEA Asset Sale Agreement in any material respect as a result of an Intentional Breach, which breach would result in a
failure of the conditions to Closing (as defined in the EMEA Asset Sale Agreement) set forth in Clause 15.3.1 thereof to be satisfied, and in each case, which, if capable of being cured, is not cured within the applicable Breach Cure Period; or

(y) any of the conditions to Purchasers obligations set forth in Section 8.1 or Section 8.3
cannot be satisfied on or before the date that is 365 days from the date of this Agreement (other than any such condition that by its nature is to be satisfied at the Closing or any such condition that cannot be satisfied as a result of (1) a
Material Intentional Purchaser Breach or (2) the failure to obtain any Antitrust Approval).

(b) If payable pursuant to
Section 9.3(a) the Reverse Termination Fee shall be paid by the Purchaser to the Distribution Agent (as agent for the Sellers and the EMEA Sellers) as follows:

(i) by application of the Good Faith Deposit and the portion of the Delay Fee that shall have already been paid to the Escrow
Agent in the form of Delay Fee Payments pursuant to Section 2.2.1(b) and the actual earnings thereon, as contemplated in Section 2.2.1(c)(ii); and

(ii) as for the balance of the Reverse Termination Fee, if any, in immediately available funds, within two (2) Business
Days of the termination of this Agreement, by way of wire transfer to an account of the Distribution Agent, as distribution agent for the Sellers, to be notified by the Main Sellers or the Distribution Agent to the Purchaser in writing.

SECTION 9.4. Effects of Termination. If this Agreement is terminated pursuant to Section 9.1:

SECTION 10.2. Remedies. No failure to exercise, and no delay in exercising, any right, remedy, power or privilege under this
Agreement by any Party will operate as a waiver of such right, remedy, power or privilege, nor will any single or partial exercise of any right, remedy, power or privilege under this Agreement preclude any other or further exercise of such right,

Agreement, all representations, warranties, covenants and agreements set forth in this Agreement or any of the Ancillary Agreements by or on behalf of the parties hereto or thereto will be binding upon and inure to the benefit of such parties and

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, 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 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.

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 EMEA Asset Sale Agreement, the Ancillary Agreements, the Confidentiality Agreement and any written notice relating to Excluded Sellers delivered pursuant to Section 5.25(a) on
the date hereof, 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 Ancillary Agreements and the 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 of the Ancillary Agreements or the Confidentiality Agreement, the provisions of this Agreement shall prevail, regardless of the fact that certain Ancillary Agreements, such as the Local Sale Agreement, may be subject
to different governing Laws (unless the Ancillary Agreement expressly provides otherwise).

(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. Limitations on Pre-Closing Remedies.

(a) Except as provided in Section 5.36, termination of this Agreement and the EMEA Asset Sale Agreement and payment of the Break-Up Fee and the Expense Reimbursement (which shall be payable only
when, as and if required pursuant to the terms of Section 9.2) shall constitute the sole and exclusive remedies of the Purchaser, any Designated Purchasers and EMEA Designated Purchasers, any of their respective Subsidiaries and any former,
current or future general or limited partners, directors, officers, employees, agents,



190



---

managers, members, Affiliates, stockholders, assignees and representatives of any of the foregoing in their capacity as such (collectively, the Avaya Parties), against the
Sellers, any of the bankruptcy estates, the EMEA Sellers, the Joint Administrators, the Joint Israeli Administrators, the Canadian Monitor (and any other Administrator, Monitor or other Person acting in a similar capacity) and any Person (i) in
which, as of or subsequent to the date hereof, any Seller or EMEA Seller holds more than fifty percent (50%) of the capital stock or other equity interests or (ii) that is or was a Seller or an EMEA Seller and their respective Affiliates,
and any former, current or future general or limited partners, directors, officers, employees, agents, managers, members, stockholders, assignees and representatives of any of the foregoing in their capacity as such (collectively, the
Nortel Parties), as a result of the failure of the transactions contemplated by this Agreement or the EMEA Asset Sale Agreement (including transactions contemplated under Clause 7 of the EMEA Asset Sale Agreement or Paragraph 2 of
Schedule 9 to the EMEA Asset Sale Agreement) to be consummated, or in respect of any Liabilities arising under, or relating to, this Agreement, the EMEA Asset Sale Agreement, or any other Transaction Document or the transactions contemplated hereby
or thereby prior to the Closing, including as a result of an intentional breach of this Agreement, the EMEA Asset Sale Agreement or any other Transaction Document prior to the Closing. Nothing set forth in this Agreement shall confer or give or
shall be construed to confer or give to any Person (including any Person acting in a representative capacity) any rights or remedies against any Person other than the parties hereto. Without limiting the preceding provisions of this
Section 10.14(a), it is acknowledged and agreed that under no circumstances shall any Person be liable for punitive damages (including multiple damages assessed as a punitive measure) or special damages arising out of, or in connection with,
this Agreement or the transactions contemplated hereby or any breach or alleged breach of any of the terms hereof or of the EMEA Asset Sale Agreement or any other Transaction Document, including damages alleged as a result of tortious conduct, or
for specific performance of the obligations it is to perform hereunder or thereunder at or prior to the Closing nor shall any Nortel Party be liable for tortious interference with Purchasers rights hereunder.

(b) Except as expressly provided in Section 5.36, in no event shall the Avaya Parties be subject to any Liability to the Nortel Parties
for the failure of the transactions contemplated by this Agreement or the EMEA Asset Sale Agreement (including transactions contemplated under Clause 7 of the EMEA Asset Sale Agreement or Paragraph 2 of Schedule 9 to the EMEA Asset Sale Agreement)
to be consummated, or in respect of any Liabilities arising under, or relating to, this Agreement, the EMEA Asset Sale Agreement or any other Transaction Document or the transactions contemplated hereby or thereby prior to the Closing, including as
a result of an intentional breach of this Agreement, the EMEA Asset Sale Agreement or any other Transaction Document prior to the Closing, other than: (i) money damages payable by the Purchaser and/or any Designated Purchaser (but, for the
avoidance of doubt, no other Avaya Party) as a result of Material Intentional Purchaser Breaches and (ii) the Reverse Termination Fee payable by the Purchaser (but for the avoidance of doubt, no other Avaya Party) when, as and if required
pursuant to Section 9.3, in an aggregate amount not to exceed the Liability Limitation Amount; provided, however, notwithstanding the foregoing, termination of this Agreement, the EMEA Asset Sale Agreement and any Transaction
Document and payment of the Reverse Termination Fee (which shall be payable by the Purchaser only when, as and if required in accordance with the terms of Section 9.3 and Clause 15.7 of the EMEA Asset Sale



191



---

Agreement), shall constitute the sole and exclusive remedies of the Nortel Parties against the Avaya Parties as a result of (and no additional money damages shall be payable by any Avaya Party in
connection with) any breach of this Agreement, the EMEA Asset Sale Agreement or any Transaction Document by the Purchaser, any Designated Purchaser or any EMEA Designated Purchaser in the event that (i) this Agreement shall have been terminated
pursuant to and in accordance with Section 9.1(i) and/or the EMEA Asset Sale Agreement shall have been terminated in accordance with Clause 15.4.9 thereof and, in either case, the Reverse Termination Fee shall have been paid to the Distribution
Agent as agent of the Sellers and the EMEA Sellers or (ii) as of the time of termination of this Agreement or the EMEA Asset Sale Agreement there is no existing Material Intentional Purchaser Breach. Nothing set forth in this Agreement shall
confer or give or shall be construed to confer or give to any Person (including any Person acting in a representative capacity) any rights or remedies against any Person other than the Parties. Without limiting the preceding provisions of this
subsection (b), it is acknowledged and agreed that under no circumstances shall any Person be liable for punitive damages (including multiple damages assessed as a punitive measure) or special damages arising out of, or in connection with, this
Agreement, the EMEA Asset Sale Agreement or the transactions contemplated hereby or thereby or any breach or alleged breach of any of the terms hereof or of the EMEA Asset Sale Agreement or any other Transaction Document, including damages alleged
as a result of tortious conduct, or for specific performance of the obligations it is to perform hereunder at or prior to the Closing nor shall any Avaya Party be liable for tortious interference with Sellers rights hereunder.

(c) Notwithstanding Sections 10.14(a) and 10.14(b), the Parties acknowledge and agree that each Party will be entitled to all the remedies
against the other Parties available to it at Law or in equity for post-Closing breaches of this Agreement, the EMEA Asset Sale Agreement and any Transaction Documents, including specific performance and/or damages.

(d) Each of the Parties acknowledges that the agreements contained in this Section 10.14, Section 9.2 and Section 9.3, are
each an integral part of the transactions contemplated by this Agreement and the EMEA Asset Sale Agreement. In the event that (i) the Sellers or the EMEA Sellers shall fail to pay the Break-Up Fee or Expense Reimbursement when due, or
(ii) Purchaser shall fail to pay the Reverse Termination Fee when due, then Sellers or the EMEA Sellers in the case of clause (i) and Purchaser in the case of clause (ii), shall reimburse the other Parties for all reasonable costs and
expenses actually incurred or accrued by such other Parties (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of Section 9.2 or Section 9.3 and Clauses 15.5 to 15.7 of the EMEA
Asset Sale Agreement as applicable, together with interest on such unpaid amount at the prime rate of Citibank N.A. in effect on the date such payment was required to be made through the date of payment.

SECTION 10.15. Bulk Sales Laws. Subject to the entry of the U.S. Sale Order, each Party waives compliance by the other Party with any
applicable bulk sales Law, provided, however, that the Parties shall use their reasonable efforts to cooperate to the extent necessary to obtain a reduction in, or exemption from, any applicable sales or use Taxes.

SECTION 10.16. Main Sellers as Representatives of Other Sellers.

(a) For all purposes of this Agreement:

(i) each Other Seller listed in Section 10.16(a)(i) of the Sellers Disclosure Schedule hereby irrevocably appoints NNL as its representative; and

(ii) each Other Seller not listed in Section 10.16(a)(i) of the Sellers Disclosure Schedule hereby irrevocably appoints
NNI as its representative.

(b) Pursuant to Section 10.16(a), each of NNL and NNI shall expressly have the power to, in
the name and on behalf of each of its Respective Affiliates (as defined below), (i) take all decisions and carry out any actions required or desirable in connection with this Agreement, (ii) send and receive all notices and other
communications required or permitted hereby, and (iii) consent to any amendment, waivers and modifications hereof.

(c)
For the purposes of this Agreement, Respective Affiliates means: (i) with respect to NNL, each Other Seller listed in Section 10.16(a)(i) of the Sellers Disclosure Schedule, and (ii) with respect to NNI, all the
other U.S. Debtors and each Other Seller not listed in Section 10.16(a)(i) of the Sellers Disclosure Schedule.

SECTION
10.17. Obligations of Sellers and EMEA Sellers. When references are made in this Agreement to certain Sellers causing other Sellers or other Affiliate(s) to undertake (or to not undertake) certain actions, or agreements are being made on
behalf of certain other Sellers or other Affiliates, Sellers for purposes of such clause shall be deemed to mean, respectively, NNI (in the case of a U.S. Debtor) and NNL (in the case of a Canadian Debtor  other than NNC - and a
Non-Debtor Seller). Notwithstanding anything to the contrary herein, except as set forth in Section 2.2.4(b) and Section 9.2(c) the obligations of each EMEA Seller hereunder shall be several and not joint. Effective as of the date of
signing, the parties are fully bound by the terms of this Agreement; provided, however, that none of the EMEA Sellers, the Joint Administrators and the Joint Israeli Administrators shall have any obligations or incur any liabilities under
this Agreement unless and until (i) the U.S. Bankruptcy Court enters the U.S. Bidding Procedures Order and (ii) the Canadian Court enters the Canadian Sales Process Order. For the avoidance of doubt, the intent of Parties and the EMEA
Sellers is that the obligations and any liabilities of the EMEA Sellers, the Joint Administrators and the Joint Israeli Administrators under this Agreement will arise concurrently with the obligations and liabilities of the Sellers under this
Agreement.

SECTION 10.18. Execution by Other Sellers. The Purchaser hereby acknowledges that the Other Sellers are not
executing this Agreement as of the date hereof. This Agreement shall be binding on all parties that have executed this Agreement from the time of such execution, regardless of whether all Sellers have done so. Between the date hereof and the Closing
Date, the Main Sellers hereby agree that they shall cause each Other Seller to execute a counterpart to this Agreement no later than the day prior to the thirtieth (30th) day following completion of the Auction (provided that the Main Sellers
shall use their reasonable best efforts to cause such execution to occur no later than the last day of the Contract Review Period),

agreeing to be bound as a Seller under this Agreement and authorizing NNL or NNI, as applicable, to act as its representative under Section 10.16.

SECTION 10.19. Exclusion of Liability of Administrators and Acknowledgement.

(a) Notwithstanding that this Agreement shall have been signed by the Joint Administrators and the Joint Israeli Administrators in their
capacities as administrators of the EMEA Debtors for and on behalf of the EMEA Debtors and of the Israeli Companies for and on behalf of the Israeli Companies, respectively, it is hereby expressly agreed and declared that no personal Liability under
or in connection with this Agreement shall fall on the Joint Administrators, the Joint Israeli Administrators or their firm, partners, employees, agents, advisers or representatives whether such Liability would arise under paragraph 99(4) of
schedule B1 to the Insolvency Act 1986, the Israeli Companies Law 1999, or otherwise.

(b) The Purchaser acknowledges and
agrees that in the negotiation and the completion of this Agreement the Joint Administrators and the Joint Israeli Administrators are acting only as agents for and on behalf of the EMEA Debtors and the Israeli Companies, respectively, and without
any personal Liability whatsoever.

(c) The Purchaser further acknowledges that it has entered into this Agreement without
reliance on any warranties or representations made by the EMEA Sellers or by any of their employees, agents or representatives, or by the Joint Administrators, the Joint Israeli Administrators or any of their firm, partners, employees, agents,
advisors or representatives and (save in respect of fraud, fraudulent misrepresentation or fraudulent misstatement) it shall not have any remedy in respect of any misrepresentation or untrue statement made by or on behalf of the EMEA Sellers or
their employees, agents or representatives, or by the Joint Administrators, the Joint Israeli Administrators or any of their firm, partners, employees, agents, advisors or representatives.
