          (b) On or before a date that is thirty (30) days from the date hereof, the Sellers shall provide to the Purchaser Section 2.1.6(b) of the Sellers Disclosure Schedule

which shall set forth a list of Non-Assignable Contracts with suppliers of products or services to the Business. On or before December 31, 2009, the Purchaser shall notify the Sellers of (i) any Non-Assignable Contracts with suppliers of products or services to the Business that the Purchaser wants the relevant Seller to attempt to assign to the Purchaser or a Designated Purchaser at the Closing (the “Designated Non-Assignable Supply Contracts”) and (ii) any Non-Assignable Contracts with suppliers of products or services to the Business that the Purchaser does not want the relevant Seller to assign to the Purchaser or a Designated Purchaser at the Closing (the “Excluded Non-Assignable Supply Contracts”).

          (e) The Parties shall use commercially reasonable efforts to obtain all Consents required to permit the assignment to the Purchaser or a Designated Purchaser of the Designated Non-Assignable Contracts; 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 and, 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.

          (f) Subject to Section 2.1.10 and Section 5.14, all the Designated Other Vendor Contracts, Designated Other Customer Contracts and the Designated Non-Assignable Contracts in force at the Closing shall be assigned to the Purchaser or a Designated Purchaser at the Closing pursuant to Section 2.1.1(c).

          2.1.8. Local Sale Agreements. Subject to the terms and conditions hereof, if reasonably requested in writing by the Purchaser or the Sellers to effect the Closing on the terms hereof, the relevant Sellers shall, and the Purchaser shall, and shall cause the relevant Designated Purchasers to, enter into such agreements or instruments, including bills of sale and/or assignment and assumption agreements (the “Local Sale Agreements”), providing for (i) the sale, transfer, assignment or other conveyance to the Purchaser and relevant Designated Purchasers, in accordance with the requirements of applicable local Law, of any Assets located in the specified countries reasonably requested by the Sellers or the Purchaser, and (ii) the assumption by the Designated Purchasers of any Assumed Liability that the Purchaser intends to allocate to them. Such Local Sale Agreements shall promptly be negotiated in good faith

between the Main Sellers and the Purchaser. In the event of a conflict between this Agreement and the Local Sale Agreements, this Agreement shall prevail.

          2.1.9. EMEA Asset Sale Agreement. Notwithstanding anything to the contrary in this Agreement, except to the extent expressly incorporated by reference into the EMEA Asset Sale Agreement, none of the EMEA Sellers or the directors of any of them, the Joint Administrators or the Joint Israeli Administrators shall assume, or be deemed to assume, any obligation or liability whatsoever under this Agreement and nothing in this Agreement shall apply to, or govern, the sale, assignment, transfer, retention or assumption of assets, rights, properties or Liabilities of, or by, any EMEA Seller, the Joint Administrators or the Joint Israeli Administrators in any manner whatsoever. The only assets, rights, properties and Liabilities of the EMEA Sellers, the Joint Administrators or the Joint Israeli Administrators that are being sold, assigned or transferred to, and assumed by, the Purchaser or the EMEA Designated Purchasers, and the terms and conditions thereof, and except as expressly set forth in this Agreement as made by the Sellers, and not, for the avoidance of doubt, the EMEA Sellers, the representations with respect thereto are solely as expressly set forth in the EMEA Asset Sale Agreement. Except as provided in the EMEA Asset Sale Agreement, neither the Purchaser nor any Designated Purchaser shall be entitled to make any claim under this Agreement, or assert any right hereunder, against any Person other than the Sellers, their successors or assigns.

          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 or assignment thereof, without the Consent of a Third Party, including a Government Entity, would constitute a breach, default, 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. In the case of Consents, Contracts and other commitments included in the Assets (i) that cannot be transferred or assigned without the consent of Third Parties, which consent has not been obtained prior to the Closing, the Sellers shall, at the Purchaser’s sole out-of-pocket cost, reasonably cooperate with the Purchaser in endeavoring to obtain such Consent and, if any such Consent is not obtained, the Sellers shall, following the Closing, at the Purchaser’s sole out-of-pocket cost, cooperate with the Purchaser in all reasonable respects to provide to the Purchaser with the benefit of such Consent, Contract or other commitment, or (ii) that are otherwise not transferable or assignable, the Sellers shall, following the Closing, at the Purchaser’s sole out-of-pocket cost, reasonably cooperate with the Purchaser to provide to the Purchaser with the benefit of such Consent, Contract or other commitment. The obligation of the Sellers to provide such reasonable cooperation under this Section 2.1.10 shall terminate on the date that is one (1) year following the Closing Date and after such time period, the Sellers shall have no further obligation to so cooperate nor shall the Sellers bear any liability for the failure to obtain such Consents within such one year period.

          SECTION 2.2. Purchase Price.

            2.2.1. Purchase Price.

          (a) Pursuant to the terms and subject to the conditions set forth in this Agreement, in consideration of the purchase, sale, assignment and conveyance of the Sellers’ and EMEA Sellers’ right, title and interest in, to and under the Assets and the EMEA Assets, respectively, pursuant to the terms hereof and pursuant to the terms of the EMEA Asset Sale Agreement, respectively, and of the rights granted by certain Sellers and the EMEA Sellers under the Intellectual Property License Agreement and the Trademark License Agreement, the Purchaser, on its own behalf and as agent for the relevant Designated Purchasers, shall (i) assume and become obligated to pay, perform and discharge, when due, the Assumed Liabilities and the EMEA Assumed Liabilities, (ii) subject to adjustment following the Closing in accordance with Section 2.2.4.2, pay to the Distribution Agent an amount of cash (the “Cash Purchase Price”) equal to Five Hundred Thirty Million dollars ($530,000,000) (the “Base Cash Purchase Price”) less the Escrow Amount and as adjusted pursuant to Sections 2.2.2 and 2.2.4 and Section 5.28 of the Sellers Disclosure Schedule or as otherwise expressly provided herein, in the Real Estate Terms and Conditions or in the EMEA Asset Sale Agreement, and (iii) subject to Section 2.2.7, issue to the Distribution Agent, as agent for the Sellers and the EMEA Sellers, $239,000,000 aggregate principal amount (the “Aggregate Principal Amount”) of 6.0% Senior Notes due June 15, 2017 (the “Convertible Notes”, and together with the Cash Purchase Price, as adjusted, the “Purchase Price”) convertible at the holder’s option into Common Stock at a conversion price equal to $16.4625 (the “Conversion Price”), subject to adjustments contemplated in the Indenture; provided, however, that the Purchaser may, by written notice to the Sellers on or before the Closing Date, elect to increase the Cash Purchase Price and the Base Cash Purchase Price payable pursuant to clause (ii) above by up to the Aggregate Principal Amount in lieu of issuing the corresponding face amount of the Convertible Notes (such election, if exercised, the “Cash Replacement Election”); provided further, that if the Market Value of the Common Stock on the date of the notice of such election (or in the case the replacement is made with the proceeds of a simultaneous convertible security offering the most recent closing price per share of the Common Stock on the NASDAQ Global Select Market at the time such convertible security offering is priced) is equal to or greater than $17.00 per share of Common Stock, then in lieu of increasing the Cash Purchase Price by the Aggregate Principal Amount such increase will equal the Optional Redemption Price corresponding to such Aggregate Principal Amount.

          (b) Except as provided in Section 2.2.1(a), the Convertible Notes shall be issued on terms substantially the same as the terms of the Existing 2017 Senior Notes as set forth in the indenture with respect thereto except that (i) references to quotation on an automated over the counter trading market contained in the “Fundamental Change” definition of the 2017 Existing Senior Notes indenture will be omitted in the equivalent definition in the documentation for the Convertible Notes, (ii) the related share adjustment amount table (with conforming changes to minimum and maximum adjustment amounts described elsewhere) is replaced by the table attached hereto as Exhibit 2.2.1(b)(ii), (iii) following the Closing but prior to the Liquidity Date, the Purchaser may redeem the Convertible Notes at any time for cash at a redemption price per $1,000 principal amount of Convertible Notes equal to the greater of (a) $1,050.00 and (b) the product of (x) the closing

price per share of the Common Stock on the NASDAQ Global Select Market on the date of notice of such redemption (or in the case of redemption with the proceeds of a simultaneous convertible bond offering the most recent closing price per share of the Common Stock on the NASDAQ Global Select Market at the time such convertible bond offering is priced) multiplied by (y) the Conversion Rate (as defined in the Indenture) applicable to the Convertible Notes on such date, as increased by a number of additional shares determined by reference to the number of such additional Shares, the most recent closing price per share of the Common Stock on the NASDAQ Global Select Market at the time the simultaneous convertible security offering is priced and the time of such redemption as set forth in the table attached hereto as Exhibit 2.2.1(b)(iii) (using the date of notice of redemption or the date of pricing of such simultaneous convertible security offering as the referenced effective date and the closing price per share of the Common Stock on The NASDAQ Global Select Market), multiplied by (z) .95, plus, in each case, accrued and unpaid interest from the date of issuance (the “Optional Redemption Price”), and (iv) the indenture with respect to the Convertible Notes will reflect the post-Closing offer requirement set forth in Section 2.2.1(c) below.

          (c) In the event that the Purchaser completes any capital raising transaction through the issuance and sale of debt or equity securities for cash during the period after the date hereof through and including the Closing Date, the Purchaser shall be required to exercise the Cash Replacement Election to the extent of the net proceeds of such capital raising transaction. In the event that the Purchaser completes any capital raising transaction through the issuance and sale of debt or equity securities for cash during the period following the Closing Date but prior to the earlier of the date on which the Initial Shelf Registration Statement becomes effective or the date on which the Registrable Securities are otherwise Freely Tradeable (such date, the “Liquidity Date”), the Purchaser shall be required to offer to use the net proceeds therefrom to replace the Convertible Notes for an amount equal to the Optional Redemption Price.

          (d) Notwithstanding Sections 2.2.1(a), (b) and (c) above, in the event that the Market Value of the Common Stock (rounded to the nearest whole cent) as of the Closing Date is less than $13.17, the interest rate on the Convertible Notes shall be increased as follows:

Market Value		Interest Rate
More than $13.16			6.00	%
$13.00-$13.16			6.25	%
$12.75-$12.99			6.50	%
$12.50-$12.74			6.75	%
$12.25-$12.49			7.00	%
$12.00-$12.24			7.25	%
$11.75-$11.99			7.50	%
$11.50-$11.74			7.75	%
Less than $11.49			8.00	%

          2.2.2. Estimated Cash Purchase Price.

          (a) For purposes of determining the amount of cash to be paid as the Cash Purchase Price by the Purchaser to the Sellers at the Closing pursuant to Section 2.2.1, at least three (3) Business Days prior to the Closing Date but no more than ten (10) Business Days prior to the Closing Date, the Main Sellers shall deliver to the Purchaser their good faith estimate of the Closing Date Net Working Capital Transferred (the “Estimated Closing Date Net Working Capital Transferred”) setting forth in reasonable detail the Main Sellers’ calculation thereof. The Main Sellers’ calculation of the Estimated Closing Date Net Working Capital shall be subject to the review and approval of the Purchaser, which approval shall not be unreasonably withheld. The Main Sellers shall cooperate with the Purchaser and shall provide such information as may be reasonably requested in connection with such review.

          (b) The “Estimated Adjustment Amount,” which may be positive or negative, shall mean (i) the Estimated Closing Date Net Working Capital Transferred, minus (ii) $167,000,000. If the Estimated Adjustment Amount is a positive number, then the Cash Purchase Price shall be increased on the Closing Date by the Estimated Adjustment Amount, and if the Estimated Adjustment Amount is a negative number, then the Cash Purchase Price shall be decreased on the Closing Date by the absolute value of the Estimated Adjustment Amount.

          (c) The Parties agree that the Cash Purchase Price to be paid at Closing shall also be decreased in accordance with clause 3.5 and Schedule 8 of the EMEA Asset Sale Agreement.

          2.2.3. Additional Adverse Bankruptcy Proceedings; Adverse International Injunctions; Excluded Entities.

          (a) Other than as set forth in Section 2.2.3(d), if at any time prior to the Closing Date, (i) any Seller that is a Non-Debtor Seller as of the date hereof shall have commenced voluntary or involuntary bankruptcy, insolvency, administration or judicial proceedings similar to the Bankruptcy Proceedings in any country or other jurisdiction (each such proceeding, an “Additional Adverse Bankruptcy Proceeding”) or (ii) there shall be in effect any Law or Order of any court or other Government Entity in any country or other jurisdiction (other than the U.S., Canada or the United Kingdom) prohibiting in such jurisdiction the consummation of the transactions contemplated hereby or any pending proceeding by any such Government Entity seeking such prohibition (such Law, Order or proceeding, an “Adverse International Injunction”), then (A) the Main Sellers shall promptly notify the Purchaser of such Additional Adverse Bankruptcy Proceeding or such an Adverse International Injunction, as applicable, and, to the extent the Main Sellers are aware of the same, identify the Assets or assets of a Person that are subject to such Additional Adverse Bankruptcy Proceeding or Adverse International Injunction (the “Restricted Assets”), (B) the Parties shall, in respect of the Restricted Assets, use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable under applicable Law to transfer, sell and assign all of the Sellers’ right, title and interest in the Restricted Assets to the Purchaser or a Designated Purchaser, as applicable, as

contemplated hereby on the Closing Date on the terms and conditions set forth herein, notwithstanding the Additional Adverse Bankruptcy Proceeding or Adverse International Injunction, as applicable; provided, however, nothing contained herein shall require the Purchaser or any Designated Purchaser to take any action in violation of applicable Law or any Order or which would subject the Purchaser or any Designated Purchaser to any material liability other than the Assumed Liabilities or to incur any material out-of-pocket cost.

          (b) If, ten (10) Business Days prior to Closing, it has become apparent to the Parties that such Additional Adverse Bankruptcy Proceeding or Adverse International Injunction will or may prevent one or more Sellers (each a “Restricted Seller”) from assigning the Restricted Assets to the Purchaser or a Designated Purchaser, as applicable, as of the Closing Date, then, as of the Closing Date, such Restricted Assets shall automatically be deemed Excluded Assets hereunder, the Sellers shall be excused from delivering the Restricted Assets and, without prejudice to all other obligations of the Purchaser and the other Sellers hereunder, the Purchaser shall be relieved from its rights and obligations to acquire such Restricted Assets, to assume any Assumed Liabilities in respect thereof (the “Restricted Liabilities”) or to make offers to, or employ, any Employee who is employed by any Seller who is subject to such Additional Adverse Bankruptcy Proceeding or Adverse International Injunction or who devotes more than 50% of his or her working time to the business of any such Sellers (each a “Restricted Employee”). The Purchase Price, including the Cash Purchase Price paid to the Sellers at the Closing, shall be reduced, with respect to such Restricted Assets and Restricted Liabilities, by an amount equal to the product of (x) the sum of the revenues for the one year period ended on December 31, 2008 (the “2008 Revenues”) for all Restricted Sellers as set forth on Exhibit X, times (y) 0.4088; provided, however, if the sum of the 2008 Revenues for all Restricted Sellers and all EMEA Sellers that are designated Restricted Sellers pursuant to the EMEA Asset Sale Agreement as set forth on Exhibit X exceeds $120,000,000, the Purchase Price, including the Cash Purchase Price paid to the Sellers at the Closing, shall be reduced, with respect to such Restricted Assets and Restricted Liabilities, by an amount equal to the product of (x) the sum of the 2008 Revenues for all Restricted Sellers as set forth on Exhibit X, times (y) 0.5314.

          (c) Subject to Section 5.4 and Section 5.5, for a period of thirty (30) days following the Closing, the Sellers and the Purchaser shall, in respect of the Restricted Assets, continue to use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable under applicable Law to assign the Restricted Assets of the relevant Restricted Seller to the Purchaser or a Designated Purchaser, as promptly as reasonably practicable within such period; provided, however, nothing contained herein shall require the Purchaser or any Designated Purchaser to take any action in violation of applicable Law or any Order or which would subject the Purchaser or a Designated Purchaser to any material liability other than the Assumed Liabilities or to incur any material out-of-pocket cost. In the event that the Sellers are unable to cause the Adverse International Injunction to be terminated or to otherwise complete the transaction in accordance with the proviso above on or before the date that is 30 days after the Closing Date, neither the Purchaser nor any Designated Purchaser shall have any further obligation

with respect to the Restricted Assets, Restricted Liabilities or the Restricted Employees. To the extent the Restricted Assets are assigned to the Purchaser or a Designated Purchaser, as applicable, the Purchaser or a Designated Purchaser shall assume the related Restricted Liabilities and make offers to and employ as provided in Article VII the Restricted Employees, then as of the transfer date: (i) the Restricted Assets, the Restricted Liabilities and the Restricted Employees shall be deemed respectively Assets, Assumed Liabilities and Transferred Employees hereunder; and (ii) the Purchaser shall pay to the Distribution Agent, as an adjustment to the Purchase Price hereunder, by wire transfer to the account designated by the Distribution Agent pursuant to Section 2.3.2(b) an amount in cash equal to the amount that the Purchase Price was reduced pursuant to subsection (b) above with respect to such Restricted Seller.

          (d) Section 2.2.3(d) of the Sellers Disclosure Schedule sets forth the manner in which certain Sellers or Affiliates of any Seller (and their Assets, and Liabilities) may be excluded from the transactions contemplated by this Agreement.

          (e) The Purchase Price, including the Cash Purchase Price, shall also be adjusted in accordance with clause 3.5 and Schedule 8 of the EMEA Asset Sale Agreement.

          2.2.4. Purchase Price Adjustment.

              2.2.4.1 Closing Statement; Dispute Resolution

          (a) As promptly as practicable (and in any event within 90 days after the Closing), the Purchaser shall prepare and deliver to the Main Sellers and the EMEA Sellers an unaudited statement (the “Closing Statement”) setting forth in reasonable detail the Net Working Capital Transferred of the Business as of the Closing Date (the “Closing Date Net Working Capital Transferred”) and each component thereof. Following the Closing, the Purchaser shall provide the Main Sellers and their representatives access to the records and employees of the Business to the extent relevant for the preparation of the Closing Statement and shall cause the employees of the Business to cooperate with the Main Sellers in connection with their review of the Closing Statement. “Net Working Capital Transferred” as of the Closing Date shall mean an amount equal to (i) the Closing Inventory Amount, plus (ii) the Closing CIP Accounts Receivable Amount, minus (iii) the Closing Warranty Provision, minus (iv) the Closing KPD Provision, minus (v) the Closing Net Deferred Revenues, minus (vi) the Closing Other Accrued and Contractual Liabilities, minus (vii) the Closing Accrued Vacation and Service Award Amount, minus (viii) the Closing Retirement Obligation Amount, minus (ix) the Excess ARD Employees Amount.

          (b) If the Main Sellers disagree with the calculation of Closing Date Net Working Capital Transferred, they shall notify the Purchaser of such disagreement in writing, setting forth in reasonable detail the particulars of such disagreement, within thirty (30) days after their receipt of the Closing Statement. In the event that the Main Sellers do not provide such a notice of disagreement within such thirty (30) day period, the Main Sellers shall be deemed to have accepted the Closing Statement and the calculation of the Closing Date Net Working Capital Transferred delivered by the Purchaser, which shall be final, binding and conclusive for all purposes hereunder. In the event any such notice of disagreement is timely provided, the Purchaser and the Main Sellers shall use commercially reasonable efforts for a period of thirty (30) days (or such longer period as they may mutually agree) to resolve any disagreements with respect to the calculations of Closing

Date Net Working Capital Transferred. If, at the end of such period, they are unable to resolve such disagreements, then the Independent Auditor as arbitrator (or such other independent accounting firm of recognized national standing as may be mutually selected by the Purchaser and the Main Sellers) (the “Accounting Arbitrator”) shall resolve any remaining disagreements. The Accounting Arbitrator shall determine as promptly as practicable, but in any event within thirty (30) days of the date on which such dispute is referred to the Accounting Arbitrator, whether the Closing Statement was prepared in accordance with the standards set forth in Section 2.2.4.1 and (only with respect to the remaining disagreements submitted to the Accounting Arbitrator) whether and to what extent (if any) Closing Date Net Working Capital Transferred require adjustment. The fees and expenses of the Accounting Arbitrator shall be paid inverse pro rata by the Primary Parties based on the final position of each of the Primary Parties as submitted to the Accounting Arbitrator relative to the Accounting Arbitrator’s final determination. The determination of the Accounting Arbitrator shall be final, conclusive and binding on the Parties. The date on which Closing Date Net Working Capital Transferred is finally determined in accordance with this Section 2.2.4.1 is hereinafter referred as to the “Determination Date.”

              2.2.4.2. Purchase Price Adjustment

          (a) The “Adjustment Amount,” which may be positive or negative, shall mean the Closing Date Net Working Capital Transferred, minus the Estimated Closing Date Net Working Capital Transferred. If the Adjustment Amount is a positive number, then the Base Cash Purchase Price shall be increased by the Adjustment Amount, and if the Adjustment Amount is a negative number, the Base Cash Purchase Price shall be decreased by the absolute value of the Adjustment Amount. The Adjustment Amount shall be paid in accordance with Section 2.2.4.2(b) below.

          (b) Adjustment Payments.

     (i) If the Adjustment Amount is a positive number (such amount, the “Increase Amount”), then, promptly following the Determination Date, and in any event within five (5) Business Days of the Determination Date:

     (A) the Purchaser shall pay to the Distribution Agent the Increase Amount, as finally determined, together with interest thereon from the Closing Date to the date of payment at the prime rate of interest published in the “Money Rates” column of the Eastern Edition of the Wall Street Journal (or the average of such rates if more than one rate is indicated) on the Closing Date (the “Prime Rate”); and

     (B) the Parties shall cause the Escrow Agent to pay to the Distribution Agent the full Working Capital Escrow Amount, together with interest thereon from the Closing Date to the date of payment at the Prime Rate.

Any cash payment of the Increase Amount shall be paid in cash by wire transfer of immediately available funds to the bank account(s) designated in writing by the Distribution Agent.

     (ii) If the Adjustment Amount is a negative number (the absolute value of such amount, the “Deficit Amount”), then, promptly following the Determination Date, and in any event within five (5) Business Days of the Determination Date:

     (A) the Parties shall cause the Escrow Agent to pay to the Purchaser, on its own behalf and in its capacity as agent for the Designated Purchasers and EMEA Designated Purchasers, the lesser of (x) the Deficit Amount, as finally determined, together with interest thereon from the Closing Date to the date of payment at the Prime Rate, and (y) the Working Capital Escrow Amount;

     (B) in the event that the Deficit Amount exceeds the Working Capital Escrow Amount, the Sellers shall cause the Distribution Agent to pay to the Purchaser, on its own behalf and in its capacity as agent for the Designated Purchasers and EMEA Designated Purchasers, an amount equal to the amount by which the Deficit Amount, as finally determined, together with the interest thereon from the Closing Date to the date of payment at the Prime Rate, exceeds the Working Capital Escrow Amount; and

     (C) to the extent that there is any Working Capital Escrow Amount remaining after payment of the Deficit Amount, such amount shall be returned to the Distribution Agent in accordance with the terms of the Escrow Agreement.

Any cash payment of the Deficit Amount shall be paid in cash by wire transfer of immediately available funds to the bank account(s) designated in writing by the Purchaser or the Distribution Agent, as applicable.

          (b) To the extent necessary to file Transfer Tax Returns, the Parties and the EMEA Sellers shall negotiate in good faith to determine an allocation of the Purchase Price (and, to the extent properly taken into account under the applicable Tax Laws, the Assumed Liabilities), among the Assets and the EMEA Assets in accordance with the principles of Section 1060 of the Code and the Treasury regulations promulgated thereunder and other applicable Tax Laws, which allocation shall be subject to the principles of Section 2.2.6(a) (such allocation, a “Partial Allocation”).

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), then such Transfer Tax Return shall be timely filed in the manner that the Party with primary responsibility for the payment of the Transfer Taxes under this Agreement reasonably determines (the “Transfer Tax Determination”), provided that such Transfer Tax Determination shall have a reasonable prospect of being sustained, and shall, upon receiving the Accounting Arbitrator’s later determination and to the extent permitted under applicable Law, the filing Party shall promptly file, or cause to be filed, an amended return in accordance therewith. The Purchaser agrees to indemnify and hold harmless the Sellers and their respective officers and directors from any Losses arising out of or resulting from the Transfer Tax Determination, including without limitation, any Tax, interest, penalty or sanction. The Parties agree 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, described above), as applicable. The Parties and the EMEA Sellers agree 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).

          2.2.7. Certain Payment Mechanics and Allocations for the Convertible Notes.

          (a) Notwithstanding anything to the contrary in this Agreement, but subject to Section 2.2.7(b) unless, prior to the Closing, the Purchaser notifies the Sellers in writing that this Section 2.2.7 shall not apply or unless the Purchaser exercises the Cash Replacement Election in full, (i) a portion of the Purchase Price payable to the Distribution Agent, as agent for the U.S. Sellers, as consideration for the U.S. Sellers’ right, title and interest in, to and under the Assets transferred by such U.S. Sellers to the Purchaser or a Designated Purchaser hereunder will include that portion of the Convertible Notes being delivered pursuant to Section 2.2.1 set forth on Section 2.2.7(a)(i) of the Sellers Disclosure Schedule and any remaining portion of the Purchase Price payable to the Distribution Agent as agent for the U.S. Sellers hereunder shall be paid to the Distribution Agent in cash as part of the Cash Purchase Price, (ii) a portion of the Purchase Price payable to the Distribution Agent, as agent for the UK Sellers, as consideration for the UK Sellers’ right, title and interest in, to and under the EMEA Assets transferred by such UK Sellers to the Purchaser or an EMEA Designated Purchaser under the EMEA Asset Sale Agreement will include that portion of the Convertible Notes being delivered pursuant to Section 2.2.1 set forth on Section 2.2.7(a)(ii) of the Sellers Disclosure Schedule and any remaining portion of the Purchase Price payable to the Distribution Agent as agent for the UK Sellers hereunder shall be paid to the Distribution Agent in cash as part of the Cash Purchase Price, (iii) a portion of the Purchase Price payable to the Distribution Agent, as agent for the Canadian Sellers, as consideration for the Canadian Sellers’ right, title and interest in, to and under the Assets transferred by such Canadian Sellers to the Purchaser or a Designated Purchaser hereunder will include that portion of the Convertible Notes being delivered pursuant to Section 2.2.1 set forth on Section 2.2.7(a)(iii) of the Sellers Disclosure Schedule and any remaining portion of the Purchase Price payable to the Distribution Agent as agent for the Canadian Sellers hereunder shall be paid to the Distribution Agent in cash as part of the Cash Purchase Price, and (iv) the Purchase Price payable as consideration for the right, title and interest in, to and under the Assets or EMEA Assets of any Non-Convertible Note Recipient Seller transferred to Purchaser, a Designated Purchaser or an EMEA Designated Purchaser will not include any Convertible Notes and shall consist entirely of cash paid to the Distribution Agent as part of the Cash Purchase Price. Neither the initial allocation of Common Stock to the U.S. Sellers, UK Sellers and Canadian Sellers, nor the allocation of a portion of the Convertible Notes in accordance with this Section 2.2.7(a) is intended by the Sellers, the EMEA Sellers or the Purchaser to establish, or otherwise serve as evidence of, the absolute or relative value of the Assets or the EMEA Assets sold by, or the Assumed Liabilities or the EMEA Assumed Liabilities assumed by the Purchaser, a Designated Purchaser or an EMEA Designated Purchaser from, any such Seller or EMEA Seller hereunder or under the EMEA Asset Sale Agreement for any purpose.

          (b) In lieu of paying any portion of the Purchase Price payable to one or more of the Convertible Note Recipient Sellers in Convertible Notes in accordance with Section 2.2.7(a), the Purchaser may, or may cause the relevant Designated Purchaser or EMEA Designated Purchaser to, deliver to the Distribution Agent, as agent for such Convertible Note Recipient Seller, a non-interest bearing, redeemable promissory note in form and substance reasonably satisfactory to the Purchaser and such Convertible Note

Recipient Seller (each a “Demand Note”) issued by the Purchaser, the relevant Designated Purchaser or EMEA Designated Purchaser to the Distribution Agent, as agent for such Convertible Note Recipient Seller, in an initial principal amount equal to the aggregate principal amount of the Convertible Notes otherwise deliverable to the Distribution Agent, as agent for such Convertible Note Recipient Seller, in accordance with Section 2.2.7(a) (the “Substituted Convertible Notes”). The Demand Note shall either be (i) redeemable upon demand by the Distribution Agent, the Convertible Note Recipient Seller or the Purchaser, by delivery by the Purchaser to the Distribution Agent, as agent for such Convertible Note Recipient Seller, Convertible Notes having an aggregate initial principal amount equal to the aggregate principal amount of the Substituted Convertible Notes or (ii) subject to put and call options allowing the Distribution Agent, the Convertible Note Recipient Seller or the Purchaser, as applicable, to exercise such option and exchange the Demand Note for Convertible Notes having an aggregate initial principal amount equal to the aggregate principal amount of the Substituted Convertible Notes; provided, that the delivery of such Demand Note shall be deemed to satisfy the Purchaser’s obligations with respect to issuance of the Substituted Convertible Notes under this Agreement only if, immediately following the Closing and on the Closing Date, the Purchaser tenders to the Distribution Agent, as agent for the applicable Convertible Note Recipient Seller, in satisfaction of, or as consideration for the acquisition of, such Demand Note, Convertible Notes having an aggregate initial principal amount equal to the aggregate principal amount of the Substituted Convertible Notes.

          (c) Without limiting the obligations of the Purchaser to pay Transfer Taxes in accordance with Section 6.1 of this Agreement or clause 11 (Tax) of the EMEA Asset Sale Agreement, and without limiting any other remedy available to the Sellers, the EMEA Sellers, the Joint Administrators or the Joint Israeli Administrators (collectively, the “Tax Indemnitees” and individually, a “Tax Indemnitee”) under this Agreement or the EMEA Asset Sale Agreement, but without duplication, the Purchaser shall indemnify the Tax Indemnitees for any Taxes imposed upon or payable by a Tax Indemnitee or for the fair value of any loss of Tax attributes arising in connection with the transactions contemplated or necessitated by this Section 2.2.7, including, without limitation, with respect to the delivery or redemption of a Demand Note, the issuance, delivery or receipt of Substituted Convertible Notes, the exercise of put or call options and any other transfer or disposition of the Convertible Notes, Demand Notes or Substituted Convertible Notes or rights in and to any of the foregoing, but not including any Taxes that would have been imposed upon or payable by a Tax Indemnitee on the assumption that Section 2.2.7 of this Agreement did not apply.

The Convertible Notes and the Shares are being acquired by the Sellers and the EMEA Sellers for investment only and not with a view to distribution, except as contemplated by this Agreement. The Sellers and the EMEA Sellers have been advised and understand that the issuance of the Convertible Notes (and, in the event of their conversion thereof, the Shares) to the Distribution Agent has not been registered under the Securities Act or under the “blue sky” or similar Laws of any jurisdiction and that the Convertible Notes and the Shares may be resold only in a transaction registered under the Securities Act and in accordance with such “blue sky” or similar Laws as may be applicable, or, subject to the terms and conditions of this Agreement, if an exemption from registration is available. The Sellers and the EMEA Sellers have been advised and understand that the Purchaser, in issuing the Convertible Notes (and, in the event of their conversion thereof, the Shares), is relying upon, among other things, the representations and warranties of the Sellers herein in concluding that such issuance is not a “public offering” and is exempt from the registration requirements of the Securities Act.

          (b) Each of the Sellers and the EMEA Sellers is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D under the Securities Act and is able to bear the risk of its investment in the Convertible Notes (and, in the event of their conversion thereof, the Shares).

          (c) Each of the Sellers and the EMEA Sellers understand that no United States federal or state agency has passed on or made any recommendation or endorsement of the Convertible Notes and the Shares or the fairness or suitability of an investment in the Convertible Notes and the Shares nor have such authorities passed upon or endorsed the merits thereof.

          (d) Each of the Sellers and the EMEA Sellers understand that the Convertible Notes and the Shares are restricted securities and must be held until an exemption from registration under the Securities Act is available and all of the requirements of such exemption have been met or unless and until the resale of such Convertible Notes and the Shares is registered under the Securities Act or subject to the terms and conditions of this Agreement and the applicable U.S. securities Laws, an exemption from registration is available.

          (e) The Sellers and the EMEA Sellers have been furnished with all materials relating to the business, finances and operations of the Purchaser and its subsidiaries and materials relating to the offer and transfer of the Convertible Notes and the Shares which have been requested by them. The Sellers and the EMEA Sellers and their advisors, if any, have been afforded the opportunity to ask such questions of the Purchaser as they deem appropriate for purposes of the investment contemplated hereby. Each of the Sellers and the EMEA Sellers understands that beneficial ownership of the Convertible Notes and the Shares involves a high degree of risk and that each may lose its entire investment in the Convertible Notes and the Shares and that each can afford to do so without material adverse consequences to its financial condition. In choosing to acquire beneficial ownership over any Convertible Notes and the Shares, none of the Sellers or the EMEA Sellers is relying on any information provided by the Purchaser and its subsidiaries, except to the extent provided herein.

          (f) The Sellers, the EMEA Sellers and their respective “Ultimate Parent Entities” (including all entities under the control of such Ultimate Parent Entities) within the meaning of the HSR Act are acquiring, and will hold, the Convertible Notes and the Shares “solely for the purposes of investment” within the meaning of Section 18a(c)(9) of the HSR Act.

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

     (i) cooperating with each other in connection with filings required under the applicable Antitrust Laws or any Laws regulating foreign investment of any jurisdiction in connection with the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement) and each Antitrust Approval, and liaising with each other in relation to each step of the procedure before the relevant Government Entities and as to the contents of all communications with such Government Entities. In particular, and except for any filings made pursuant to the Investment Canada Act, no Party will make any notification or other filing with or to any Government Entity in relation to the transactions contemplated hereunder without first providing the other Party or its outside counsel on an outside counsel only basis with a copy of such notification in draft form (except with respect to any documents relating to Item 4(c) of the notification form required by the HSR Act) and giving such other party or its outside counsel a reasonable opportunity to discuss its content before it is filed with the relevant Government Entities, and such first Party shall consider and take account of all reasonable comments timely made by the other Party or its outside counsel in this respect. For the avoidance of doubt, draft filings, materials or information provided under this section or under any other provision of this Agreement to the other Party’s counsel on an outside counsel only basis shall only be given to outside counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient without the advance written consent of the Party providing such draft filing or materials;

     (ii) furnishing to the other party or its outside counsel in a timely fashion all information within its possession that is required for any application or other filing to be made by the other party pursuant to the applicable Antitrust Laws or any Laws regulating foreign investment of any jurisdiction in connection with the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement); provided, however, that no such information shall be required to be provided by a Party if it determines, acting reasonably, that the provision of such information would jeopardize any attorney-client or other legal privilege (it being understood, however, that the Parties shall cooperate in any reasonable

efforts and requests that would enable otherwise required disclosure to the other Party or its outside counsel to occur without so jeopardizing the privilege);

     (iii) promptly notifying each other of any communications from or with any Government Entity with respect to the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement) and ensuring that each of the parties or its outside counsel (as determined by the Purchaser in its reasonable discretion in the case of meetings or appearances related to ICA Approval), where acceptable to the Government Entity, is represented at any meetings with or other appearances before any Government Entity with respect to the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement); and

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

               (d) In addition, and subject to Section 5.5(e), the Purchaser shall, and shall cause each of the Designated Purchasers to, use its reasonable efforts to satisfy (or cause the satisfaction of) the conditions precedent to the Purchaser’s obligations hereunder as set forth in Section 9.1(a) to the extent the same is within its control and to take, or cause to be taken, all other actions and to do, or cause to be done, all other things necessary, proper or advisable under all applicable Laws to consummate the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement), including using its reasonable efforts to obtain all Regulatory Approvals, and any other Consent of a Government Entity required to be obtained in order for the Parties to consummate the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement).

               (e) The obligations of the Purchaser pursuant to Section 5.5(d) shall include committing, and causing the Designated Purchasers to commit, to any and all undertakings, divestitures, licenses or hold separate or similar arrangements with respect to their respective assets and/or the Assets and/or the EMEA Assets and/or to any and all arrangements for the conduct of any business and/or to any termination of any and all existing relationships and contractual rights and obligations as a condition to obtaining any and all Consents from any Government Entity necessary to consummate the transactions contemplated by this Agreement (and/or by the EMEA Asset Sale Agreement), including taking, and causing the Designated Purchasers to take, any and all Consents from any Government Entity necessary to consummate the transactions contemplated hereby, including taking any and all actions necessary in order to ensure the receipt of the necessary Consents and Regulatory Approvals; provided, however, that nothing in this Agreement or the EMEA Asset Sale Agreement shall require or be construed to require the Purchaser, any Designated Purchaser, any EMEA Designated Purchaser or any of their respective Subsidiaries to commit to any undertaking, divestiture, license or hold separate or similar arrangement or conduct of business arrangement or to terminate any relationships, rights or

obligations or to do any other act, to the extent such commitment, termination or action would be reasonably likely to be materially adverse to the Business or the Purchaser, or financial condition or prospects of the Business or the Purchaser.

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

          SECTION 5.6. Pre-Closing Access to Information.

               (a) Prior to the Closing, the Sellers shall, and shall cause their Subsidiaries (other than the EMEA Sellers) to, (i) give the Purchaser and its authorized representatives, upon reasonable advance notice and during regular business hours, reasonable access to all books, records, personnel, officers and other facilities and properties of the Business (excluding the EMEA Business), (ii) permit the Purchaser to make such copies and inspections thereof, upon reasonable advance notice and during regular business hours, as the Purchaser may reasonably request, (iii) grant the Purchaser and its representatives reasonable access to each of the facilities of the Business where Assets are located for purposes of completing an updated inventory of the fixed assets of the Business for purposes of completing an appraisal of the value thereof, and (iv) cause the officers of the Sellers to (A) after each month-end promptly (and in any event within thirty (30) days thereafter) furnish the Purchaser with copies of the Sellers’ standard Business review of orders and revenue as is regularly prepared in the Ordinary Course, and (B) after each quarter-end promptly (and in any event within thirty (30) days thereafter) furnish the Purchaser with an unaudited quarter-end balance sheet for the Business as of the end of such quarter, and unaudited combined statements of earnings and cash flows of the Business for the three (3) month period then ended; provided, however, that (1) any such access shall be conducted at the Purchaser’s expense, in accordance with Law (including any applicable Antitrust Laws and Bankruptcy Laws), at a reasonable time, under the supervision of the Sellers’ personnel and in such a manner as to maintain confidentiality and not to unreasonably interfere with the normal operations of the businesses of the Sellers and their Affiliates, and (2) the Sellers will not be required to provide to the Purchaser access to or copies of any Tax records except as otherwise provided herein.

               (b) In order to facilitate the Purchaser’s entry into new supply arrangements effective as of the Closing, the Sellers shall make available to the Purchaser unredacted copies of all Contracts with suppliers of the Business, or in the case of any Non-Exclusive Supply Contracts, unredacted copies of any portion thereof that are applicable to the Business (other than pricing/cost information or other competitively sensitive information the sharing of which Sellers or their representatives reasonably determine may violate applicable Law), promptly following the date hereof (or in the event that any such Contract is subject to confidentiality restrictions promptly following the receipt of any required consent which the Sellers will cooperate with the Purchaser to obtain as promptly as practicable). So long as the Purchaser is the winning bidder in the Auction, the Sellers shall provide such information not provided in accordance with the preceding sentence upon the later of the entry of the U.S. Sale Order, the receipt of the HSR Approval and the receipt of the Competition Act Approval. Any such disclosures shall be made to any employees or

representatives of the Purchaser who are designated by the Purchaser, who reasonably require access to such information for any reasonable business purpose related to the acquisition of the Business by the Purchasers and who have executed the applicable “Clean Room Agreements,” provided, however, that employees of the Purchaser shall not have access to such information unless they are not involved in making decisions regarding pricing or the other material competitive terms offered to any customer of a competing business to the Business, and if the transaction does not close, agree not to be employed in such a role for an agreed-upon minimum period of time.

               (c) In connection with the procedures set forth in Section 5.15 with respect to the Bundled Contracts, the Sellers will provide unredacted copies of any portion of any Bundled Contracts that relates to the Business (other than pricing information and other competitive sensitive information the sharing of which the Sellers or their representatives reasonably determine may violate applicable Law) promptly following the date hereof, and so long as the Purchaser is the winning bidder in the Auction, will provide such information upon the later of the entry of the U.S. Sale Order, the receipt of the HSR Approval and the receipt of the Competition Act Approval. Any such disclosures shall be made to any employees or representatives of the Purchaser who are designated by the Purchaser, who reasonably require access to such information for any reasonable business purpose related to the acquisition of the Business by the Purchasers and who have executed the applicable “Clean Room Agreements,” provided, however, that employees of the Purchaser shall not have access to such information unless they are not involved in making decisions regarding pricing or the other material competitive terms offered to any customer of a competing business to the Business, and if the transaction does not close, agree not to be employed in such a role for an agreed-upon minimum period of time.

               (d) Promptly following the date hereof, the Sellers will provide to Purchaser a correct and complete list of table values from the Sellers’ SAP HR system for the following fields: (i) job, (ii) organization/HR Department, and (iii) location. Within twenty (20) days following the date hereof, the Sellers will provide to the Purchaser a set of test files from the Sellers’ SAP HR system, which shall include actual employee data (including at least one person per country), but excluding in such data any information revealing the identity of any Employees (including names, addresses, tax identification numbers and any other information that would allow the Purchaser to individually identify any Employee). Such test files shall be in the same format as the format that will be subsequently provided to the Purchaser by the Sellers when actual payroll data is transferred from the Sellers to the Purchaser. Within three (3) Business Days following the completion of the Auction, the Sellers will provide the following additional information with respect to each of the Employees whose information was provided in Section 4.10(b) of the Sellers Disclosure Schedule: (i) full name, (ii) work e-mail address, (iii) work telephone number, (iv) specific recurring allowances paid to employees (if applicable), (v) supervisor and (vi) pay schedule. Within three (3) Business Days following the notification from Purchaser to Sellers of any Identified Employee pursuant to Section 7.1.1, the Sellers will provide Purchaser with the Identified Employee’s home address. Additionally, provided that Purchaser provides Seller with proof that an Identified Employee has consented to its release and, if applicable, transfer across boundaries, the Sellers will provide the Purchaser with the following additional information with respect to such Identified Employees as soon as

practicable following the receipt by Seller of such proof: (ix) tax identification number, (x) date of birth, and (xi) gender. In addition, upon Purchaser’s reasonable request, the Sellers will promptly provide Purchaser with aggregate census data with respect to gender and age (using five-year bands) of the Identified Employees’ employee population (without individually identifying any Identified Employee).

               (e) Notwithstanding anything contained in this Agreement or any other agreement between the Purchaser and the Sellers executed on or prior to the date hereof, the Sellers shall not have any obligation to make available to the Purchaser or its representatives, or provide the Purchaser or its representatives with, (i) any Tax Return filed by the Sellers or any of their Affiliates or predecessors or (ii) any other information, if in each case under subsection (i) and (ii), making such information available would (A) jeopardize any attorney-client or other legal privilege or (B) potentially cause the Sellers to be found in contravention of any applicable Law or contravene any fiduciary duty or agreement (including any confidentiality agreement with a Third Party to which the Sellers or any of their Affiliates are a party) between Sellers and a Third Party, it being understood that the Sellers shall cooperate in any reasonable efforts and requests for waivers that would enable otherwise required disclosure to the Purchaser to occur without so jeopardizing privilege or contravening such Law, duty or agreement.

               (f) Promptly following the date of the U.S. Sale Order, the Sellers agree to provide the Purchaser with access to such documentation, records and databases to the extent reasonably required to review and assess the Sellers’ use of Open Source Software incorporated into any of the Products or Services.

          SECTION 5.7. Public Announcements. The initial press release relating to this Agreement shall be a joint press release, the text of which shall be agreed to by the Purchaser and the Sellers acting reasonably. Unless otherwise required by applicable Law or by obligations of the Parties or their Affiliates pursuant to any listing agreement with or rules of any securities exchange, the Parties hereto shall consult with each other before issuing any other press release or otherwise making any public statement with respect to this Agreement, the transactions contemplated hereby or the activities and operations of the other Party and shall not issue any such release or make any such statement without the prior written consent of the other Party (such consent not to be unreasonably withheld or delayed).

          SECTION 5.8. Further Actions. From and after the Closing Date, each of the Parties shall execute and deliver such documents and other papers and take such further actions as may reasonably be required to carry out the provisions of this Agreement and the other Transaction Documents to which they are a party and give effect to the transactions contemplated herein and therein, including the execution and delivery of such assignments, deeds and other documents as may be necessary to transfer any Assets as provided in this Agreement, including the assignment of any Assigned Contract; provided, that subject to Section 5.5, the Sellers shall not be obligated to make any payment or deliver anything of value to any Third Party (other than filing and application fees to Government Entities, all of which shall be paid or reimbursed by the party required to pay such fees under the Agreement) in order to obtain any Consent to the transfer of Assets or the assumption of Assumed Liabilities.

          SECTION 5.9. Conduct of Business. The Sellers covenant that, subject to any limitation imposed as a result of being subject to the Bankruptcy Proceedings and except as (i) the Purchaser may approve otherwise in writing as set forth below (such approval not to be unreasonably withheld or delayed), (ii) set forth in Section 5.9 of the Sellers Disclosure Schedule, (iii) otherwise contemplated or permitted by this Agreement or another Transaction Document, (iv) required by Law (including any applicable Bankruptcy Laws or by any order of a Bankruptcy Court), or (v) relates solely to Excluded Assets or Excluded Liabilities, the Sellers shall and shall cause their Affiliates to (A) conduct the Business and maintain the Owned Equipment in the Ordinary Course, (B) use efforts that are commercially reasonable in the context of the Bankruptcy Proceedings and taking into account employee attrition to continue operating the Business (excluding the EMEA Business) as a going concern, and to maintain the business organizations of the Business (excluding the EMEA Business) intact and (C) abstain from any of the following actions:

               (d) increase the rate of cash compensation or other fringe, incentive, equity incentive, pension, welfare or other employee benefits payable to the Employees, other than normal periodic increases consistent with past practice or as required by applicable Law, Contracts or Seller Employee Plans in effect as of the date hereof, or pursuant to the KEIP or KERP (provided that the Sellers provide the Purchaser with notice of amendments, modifications, supplements or replacements to the KEIP as may be approved by the Canadian Court or to the KERP as may be approved by the Canadian Court or the U.S. Bankruptcy Court), or increases to welfare benefits that apply to substantially all similarly situated employees (including the Employees) of the Sellers or the applicable Affiliates of the Sellers, or (ii) except as otherwise expressly permitted under Section 5.9, enter into, or increase the benefits or any payments under, any employment, deferred compensation, severance or other similar agreement or arrangement with any Employee;

               (e) voluntarily terminate or waive any material right under, or materially amend any Material Contract or any Bundled Contract material to the Business (other than as necessary to effect the unbundling of any Bundled Contract required with respect to any other business or business segment of the Sellers), unless such Contract has become an

Excluded Other Vendor Contract, an Excluded 365 Vendor Contract or a Non-Assigned Contract;

               (f) waive, release, assign, settle or compromise any material claim, litigation or arbitration relating to the Business to the extent that such waiver, release, assignment, settlement or compromise imposes any binding obligation, whether contingent or realized, on the Business that will bind the Designated Purchasers after the Closing Date and is materially adverse to the Business;

               (g) fail to make any budgeted capital expenditures with respect to the Business (excluding the EMEA Business) or make any unbudgeted capital expenditure with respect to the Business (excluding the EMEA Business) in excess of $100,000 individually or $250,000 in the aggregate;

               (s) authorize, or commit or agree to take, any of the foregoing actions.

If a Seller desires to take any action described in this Section 5.9, the Main Sellers may, prior to any such action being taken, request the Purchaser’s consent via an electronic mail or facsimile sent to the individual(s) at the addresses listed on Exhibit 5.9. The Purchaser shall respond to such notice in writing by 11:59 p.m. (New York time) on the second Business Day after the day of delivery of such electronic mail or facsimile. The failure of the Purchaser to respond within such two (2) Business Days shall not be deemed to be consent to such action.

The Purchaser acknowledges and agrees that: (i) prior to the Closing Date, the Sellers shall exercise, consistent with the terms and conditions of this Agreement, control and supervision of the Business (excluding the EMEA Business) and the EMEA Sellers shall exercise, consistent with the terms and conditions of the EMEA Asset Sale Agreement, the EMEA Business and (ii) notwithstanding anything to the contrary set forth in this Agreement, no consent of the Purchaser shall be required with respect to any matter set forth in Section 5.9 or elsewhere in this Agreement to the extent the requirement of such consent would, upon advice of the Purchaser’s counsel, violate any Law.

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

          SECTION 5.11. Confidentiality.

               (a) The Parties acknowledge that the Confidentiality Agreement remains in full force and effect in accordance with its terms, which are incorporated herein

by reference, and the Parties agree to be bound thereby in the same manner and to the same extent as if the terms had been set forth herein in full, except that the Sellers shall be at liberty to disclose the terms of this Agreement to any court or to any liquidator or in connection with any auction process with respect to the Business or the Assets approved by the Bankruptcy Court and show appropriate figures in their administration records, accounts and returns; provided, that after the completion of the transactions contemplated herein, the Purchaser’s confidentiality obligations under this Section 5.11 and the confidentiality agreement between the Purchaser, NNC and its subsidiaries and Alan Bloom dated March 27, 2009, with respect to information and data relating to the Business and/or the Assets shall terminate. For greater certainty, the Purchaser’s confidentiality obligations under the third clean team confidentiality agreement between the Purchaser and its subsidiaries and NNL and its subsidiaries, dated June 19, 2009, shall not terminate after the completion of the transactions contemplated herein.

               (b) Subject to the requirements of the Bankruptcy Laws or as may be imposed by the Bankruptcy Court or as otherwise required by applicable Law, from and after the Closing: (i) the Sellers shall, and shall cause their Affiliates to, hold in confidence all confidential information (including trade secrets, customer lists, marketing plans and pricing information) of the Sellers relating to the Business or the Assets; (ii) in the event that the Sellers or an Affiliate thereof shall be legally compelled to disclose any such information, the Sellers shall provide the Purchaser with prompt written notice of such requirement so that the Purchaser may seek a protective order or other remedy; and (iii) in the event that such protective order or other remedy is not obtained, the Sellers or their Affiliates shall furnish only such information as is legally required to be provided.

               (c) It is acknowledged by the Purchaser and the Sellers that in the course of attempting to sell the Assets, one or more of the Sellers has entered into several confidentiality agreements with Third Parties in respect of information relating to the Assets and has disclosed such information to certain of those Third Parties.

               (d) Each Seller shall assign to the Purchaser, at or prior to, and with effect from and after the Closing, all of its rights under any such confidentiality agreement made by such Seller with any Third Party but only as such confidentiality agreements relate to the Assets and the Business and only to the extent that such agreements permit such assignments without the consent of any Third Party. To the extent such agreements do not permit any assignment without the consent of any Third Party, at the Purchaser’s request and the Purchaser’s expense, provided that the Sellers receive an indemnity from the Purchaser in form and substance satisfactory to the Sellers, to the extent permitted by applicable Laws and the terms of such confidentiality agreements, shall appoint the Purchaser as such Sellers’ representative and agent in respect of confidential information relating to the Business and Assets under such confidentiality agreements and any amounts recovered or expenses incurred in enforcing those confidentiality agreements in respect of the Sellers shall accrue to the benefit of or be for the account of the Purchaser.

               (e) Notwithstanding anything to the contrary contained in this Section 5.11, nothing contained in this Agreement shall be construed as precluding, prohibiting, restricting or otherwise limiting the ability of the Sellers, the Sellers’ Affiliates or their respective representatives to: (i) make permitted disclosures under Section 5.7 or as

otherwise permitted under this Agreement; (ii) make any disclosures that are required by applicable Law; (iii) use or disclose information that is not exclusive to the Business to the extent necessary to 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; (iv) perform any retained Contracts, whether or not exclusively related to the Business; or (v) make customary disclosures, subject to customary confidentiality agreements, regarding 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). Notwithstanding anything to the contrary contained in this Section 5.11, nothing contained in this Agreement shall be construed as precluding, prohibiting, restricting or otherwise limiting the ability of the Purchaser, the Purchaser’s Affiliates or their respective representatives to: (i) make permitted disclosures under Section 5.7 or as otherwise permitted under this Agreement or (ii) make any disclosures that are required by applicable Law.

          SECTION 5.12. Disclosure Schedules and Certain Information.

               (a) The Sellers shall submit to the Purchaser via electronic mail or facsimile sent to the individual(s) at the addresses listed in Exhibit 5.12, every two (2) weeks, written updates to Section 4.10(b) of the Sellers Disclosure Schedule with respect to additions, deletions or other status changes of Employees or, after finalization of the Identified Employees, only with respect to Identified Employees. The Sellers shall submit to the Purchaser at least three (3) Business Days prior to the Closing Date, written updates to the Sellers Disclosure Schedules in respect of Article IV disclosing any events or developments that occurred or any information learned between the date of this Agreement and the Closing Date that reflect any matters hereafter arising which, if existing, occurring or known to the Sellers at the date hereof, would have been required to be set forth or described in the Sellers Disclosure Schedule in relation to Article IV.

               (b) The Sellers shall give prompt notice to the Purchaser, and the Purchaser shall give prompt notice to the Sellers, upon obtaining knowledge of the occurrence or nonoccurrence of any event that, individually or in the aggregate, would make the timely satisfaction of the conditions set forth in Article IX impossible or unlikely.

               (c) The delivery of any update or notice pursuant to this Section 5.12 shall not cure any breach of any representation or warranty requiring disclosure of such matter or otherwise limit or affect the remedies available hereunder to any party receiving such notice.

          SECTION 5.13. Certain Payments or Instruments Received from Third Parties. To the extent that, after the Closing Date, (a) the Purchaser or any Designated Purchaser receives any payment or instrument that is for the account of a Seller according to the terms of this Agreement or relates primarily to any business or business segment of the Sellers other than the Business, the Purchaser shall, and shall cause the Designated Purchasers to promptly deliver such amount or instrument to the relevant Seller, and (b) any of the Sellers receives any payment that is for the account of the Purchaser or any of the Designated Purchasers

according to the terms of this Agreement or relates primarily to the Business, the Main Sellers shall, and shall cause the Other Sellers to promptly deliver such amount or instrument to the Purchaser or the relevant Designated Purchasers. All amounts due and payable under this Section 5.13 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 5.14. Non-Assignable Contracts.

               (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 without the Consent of the issuer thereof or the other party thereto 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, unless any such Consent is obtained.

               (b) For the purposes of this Agreement (including Section 5.14(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 365 Vendor Contract and 365 Customer Contract if, and to the extent that, pursuant to the U.S. Sale Order, the Sellers are authorized to assume and assign to the Purchaser or Designated Purchasers such Seller Contract pursuant to Section 365 of the U.S. Bankruptcy Code and any applicable Cure Cost has been, or will be, satisfied as provided in Section 2.1.7. In furtherance thereof, the U.S. Bidding Procedures Order shall contain procedures, in form and substance acceptable to the Purchaser, for obtaining U.S. Bankruptcy Court approval that all 365 Contracts other than the Non-Assignable Contracts can and shall be assigned to the Purchaser on the Closing Date.

          SECTION 5.15. Bundled Contracts.

               (a) Section 5.15 of the Sellers Disclosure Schedule lists each Contract that the Sellers or their Affiliates have entered into prior to the date hereof providing for the sale or provision of Products and/or Services and the sale or provision of other products and services of the Sellers or their Affiliates (each, a “Bundled Contract”).

               (b) During the period from the date hereof until the Auction, the Sellers and their Affiliates shall cooperate (consistent with applicable Laws and any confidentiality restrictions requiring consent of Third Parties) with the Purchaser in developing a strategy with respect to transitioning each customer of the Business that is party to a Bundled Contract by, among other things, making available those employees who are responsible for managing the customer relationship with each such customer, by providing unredacted copies of all Contracts to which any Seller is a party (or in the case of Bundled Contracts, the portions of such Bundled Contracts as are applicable to the Business) with each of the top 40 customers of the Business by revenue for the year ended December 31, 2008 (other than pricing information and other competitive sensitive information the sharing of which Sellers or their representatives reasonably determine may violate applicable Law) and such

          SECTION 5.19. Financing. Notwithstanding anything to the contrary set forth herein, the Purchaser acknowledges and agrees that (i) its obligations to consummate the transactions contemplated by this Agreement are not conditioned or contingent in any way upon receipt of any financing and the failure to consummate the transactions contemplated herein as a result of the failure to obtain financing shall constitute a breach of this Agreement by the Purchaser (including its obligations pursuant to Section 2.3).

          SECTION 5.20. 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 (excluding the EMEA Business) (collectively, the “Covered Assets and Persons”) under all current or previous insurance policies of the Sellers and their Affiliates, including, without limitation, all environmental, directors’ and officers’ Liability, fiduciary Liability, employed lawyers, property and casualty flood, ocean marine, contaminated products and all other insurance policies or programs arranged or otherwise provided or made available by the Sellers or their Affiliates that cover (or covered) any of the Covered Assets and Persons at any time prior to the Closing (the “Seller Insurance Policies”) shall cease as of the Closing Date and the Covered Assets and Persons will be deleted in all respects as insured (or additional insured, as the case may be) under all Seller Insurance Policies. Except as expressly provided herein, 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 (excluding the EMEA Business).

               (b) If after the Closing Date the Purchaser or the Sellers (or any of their respective Affiliates) reasonably require any information regarding claim data or other information pertaining to a claim or an occurrence reasonably likely to give rise to a claim (including any pre-Closing claims under the Seller Insurance Policies that are to be covered under the retrospective component of the new insurance policy) in order to give notice to or make filings with insurance carriers or claims adjustors or administrators or to adjust, administer or otherwise manage a claim, then the Sellers or the Purchaser, as the case may be, shall cause such information to be supplied to the other (or their designee), to the extent such information is in their possession and control or can be reasonably obtained by the Sellers or the Purchaser (or their respective Affiliates), as applicable, promptly upon a written request 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 maintain the Seller Insurance Policies, or in the event any such policies are cancelled or otherwise terminated, shall obtain other substantially comparable insurance policies that have the same coverage limits and deductibles or self-retention amounts. In respect of insurance claims relating to the Owned Equipment (excluding for the purposes of this Section 5.20(c), any fixtures and improvements forming part of the Carling Property) or the premises subject to a Real Estate Agreement (except for the Carling Property) occurring prior to Closing, the following provisions shall apply:

     (i) The Sellers shall make and diligently pursue any applicable insurance claims related to damage or destruction to any Owned Equipment wherever located.

     (ii) 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 (or which would have been received had the Sellers maintained the Seller Insurance Policies) in respect of such Owned Equipment 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. In the event that insurance proceeds would have been available but for the Sellers’ failure to maintain the Seller Insurance Policies, or due to the rights of any superior lender, then in such event, the Purchase Price shall be reduced by an amount equal to the cost of repair, or, if destroyed or damaged beyond repair, by an amount equal to the cost of replacing the Owned Equipment so damaged or destroyed with equipment of comparable age and condition.

     (iii) Except in respect of the Carling Property, if and to the extent that any leasehold improvements at any premises subject to a Real Estate Agreement are destroyed or damaged prior to Closing, then to the extent of the receipt of insurance proceeds relating to such damage or destruction by the Sellers or which would have been received had the Sellers complied with the Seller Insurance Policies, or tenant’s insurance requirements under the applicable Lease, as applicable (but excluding any proceeds related to business interruption insurance or related to any part of any premises in the applicable building not forming part of the premises subject to a Real Estate Agreement) the Sellers shall be responsible to the extent required under the terms of the applicable Lease, to utilize such insurance proceeds received to restore the applicable improvements and leasehold improvements in accordance with the provisions of the applicable Lease. To the extent that any Real Property which is the subject of a Real Estate Agreement is destroyed or damaged after Closing, the applicable terms of the

applicable Real Estate Agreement shall apply; and to the extent that the subject Real Estate Agreement provides that it is the responsibility of the landlord to repair or restore any destruction or damage to real or personal property, the Sellers shall make and diligently pursue any applicable claims against the landlord related to such damage or destruction.

               (d) If and to the extent that the Carling Property is destroyed or damaged prior to Closing and the Purchaser does not elect to terminate this Agreement pursuant to Section 10.1(f), hereof, then to the extent of the Sellers’ receipt of insurance proceeds relating to such damage or destruction or which would have been received had the Seller maintained the Seller Insurance Policies, (but excluding any proceeds related to business interruption insurance), and subject to the rights of any superior landlord or mortgagee in respect of the Carling Property, the Sellers shall be responsible to the extent required under the terms of the Carling Property Lease Agreements (as if such Lease Agreements 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 fixtures to a condition substantially comparable to the condition prior to such damage or destruction. In the event that (i) insurance proceeds are not immediately available to the Sellers on Closing for purposes of the repair and restoration of the Carling Property (including any fixtures and tenant improvements forming a part thereof); or (ii) insurance proceeds would have been available but for the Sellers’ failure to maintain the Seller Insurance Policies, or due to the rights of any superior landlord or mortgagee, the Purchaser may withhold from the Purchase Price due on Closing and pay into the Escrow Account an amount equivalent to the aggregate cost of repairing such damage and restoring the Carling Property (including any fixtures and improvements forming a part thereof) to a condition substantially comparable to the condition prior to such damage or destruction (such cost to be determined by an independent and qualified architect or engineer mutually acceptable to the Sellers and Purchaser, each acting reasonably). The provisions of Article II.C of the Real Estate Terms and Conditions shall apply mutatis mutandis in respect of these escrow amounts and the completion of the repair and restoration works. To the extent that the Carling Property is destroyed or damaged after Closing, the terms of the Carling Property Lease Agreements shall apply.

               (a) Following the Closing, the Purchaser shall, or shall cause the applicable Designated Purchaser to, cooperate with the Sellers to procure the return and/or release by the applicable counterparty, as soon as reasonably practicable, of any lease security deposits given by the Sellers under any Leases that are Assigned Contracts or any deposits, bonds or other security posted in connection with Assigned Contracts and that are set forth in Section 5.21(a) of the Sellers Disclosure Schedule (which such Section of the Sellers Disclosure Schedule may be updated by the Sellers upon notice to the Purchaser up until three (3) Business Days prior to the Closing Date) (the “Security Deposits”), including where required by the applicable counterparty, offering to post such Security Deposits on terms and conditions no less favorable than offered to such Seller by such counterparty. Except as required by the immediately preceding sentence, the Purchaser shall in no event be required to provide any replacement financial security or any financial security or other deposits with

respect to any premises leased pursuant to any lease or sublease arrangement with any Seller, all of which shall be the sole responsibility of the Seller.

               (b) The Purchaser shall, or shall cause the applicable Designated Purchaser to, hold the Sellers and their Affiliates harmless from and against any and all Losses suffered by the Sellers and their Affiliates resulting from, or relating to, the failure of the Purchaser or the applicable Designated Purchaser, as the case may be, to procure the return and/or release of the Security Deposits to the relevant Seller in accordance with Section 5.21(a); provided, however, that (i) the Purchaser shall have no liability to the Sellers and their Affiliates pursuant to this Section 5.21(b) unless the Sellers and their Affiliates assign to the Purchaser all of the Sellers’ and their Affiliates’ right, title and interest in the unreturned Security Deposits and (ii) the Purchaser’s liability to the Sellers and their Affiliates shall be limited, in each case, to the amount of such Security Deposits.

          SECTION 5.22. Use of Sellers’ Trademarks. Except as expressly provided in the Trademark License Agreement, as of the Closing Date, the Purchaser shall not have the right to use 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 part or variation of any of the foregoing or any confusingly similar Trademarks to any of the foregoing (collectively, the “Sellers’ Trademarks”).

          SECTION 5.23. Accessible Information. After the Closing, the Purchaser shall have the right to reasonably request from the Main Sellers copies of all books, records, files, documentation and sales literature (other than Tax records and Employee Records, except as provided in Sections 5.6(d) and 7.4(d)) in the possession or under control of the Sellers and held or used in the Business (other than records to the extent prohibited by applicable Law), to which the Purchaser in good faith determines it needs access for bona fide business or legal purposes. The Sellers shall use commercially reasonable efforts to, or cause their Respective Affiliates to use commercially reasonable efforts to, provide such copies to the Purchaser (at the Purchaser’s expense) as soon as reasonably practicable; provided, that the Sellers shall be allowed to redact any such requested document in order to delete any information and data relating to business segments of any such Seller and its Respective Affiliates not included in the Business; provided, further, that nothing herein shall require the Sellers to (i) disclose any information to the Purchaser if such information disclosure would jeopardize any attorney-client or legal privilege or (ii) contravene any applicable Law, fiduciary duty or agreement (including any confidentiality agreement to which the Sellers or any of their Affiliates is a party); it being understood, that the Sellers shall cooperate in any reasonable efforts and requests for waivers that would enable otherwise required disclosure to the Purchaser to occur without so jeopardizing privilege or contravening such Law, duty or agreement).

          SECTION 5.24. Maintenance of Books and Records. After the Closing, each Primary Party shall, and shall cause its Affiliates to, preserve, until at least the third (3^rd) anniversary of the Closing Date (or, in the case of Tax records (including VAT records), such later date as may be required by 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 up until at least the third (3^rd) anniversary of the Closing Date, upon any reasonable request from any Primary Party or its representatives, the other Primary Party shall, and/or shall cause the Person holding such records to, (a) provide to the requesting Primary Party or its representatives

reasonable access to such records during normal business hours and (b) permit the requesting Primary Party or its representatives to make copies of such records, in each case at no cost to the requesting Primary Party or its representatives (other than for reasonable out-of-pocket expenses). In addition, in the event that the financial statements of the Business are audited for any period prior to the Closing Date, upon execution of a customary access letter if required, the requesting Primary Party and its representatives (including their outside accountants) shall be granted access to all relevant documents and information in connection with the requesting Primary Party completing the audit of its accounts for the 2009 fiscal year; provided, however, that nothing herein shall require the non-requesting Primary Party to disclose any information to the requesting Primary Party 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 non-requesting Primary Party shall cooperate in any reasonable efforts and requests for waivers that would enable otherwise required disclosure to the requesting Primary Party to occur without so jeopardizing privilege or contravening such Law, duty or agreement). Such records may be sought under this Section 5.24 for any reasonable purpose, including to the extent reasonably required in connection with accounting, litigation, federal securities disclosure or other similar needs of the requesting Primary Party (other than claims between the Primary Parties or any of their respective Subsidiaries under this Agreement or any Ancillary Agreement). Notwithstanding the foregoing, any and all such records may be destroyed by the non-requesting Primary Party if the non-requesting Primary Party sends to the requesting Primary Party written notice of its intent to destroy such records, specifying in reasonable detail the contents of the records to be destroyed; (i) such records may then be destroyed after the 60^th day following such notice unless the requesting Primary Party notify the destroying party that the requesting Primary Party desire to obtain possession of such records, in which event the non-requesting Primary Party shall transfer or cause to be transferred the records to the requesting Primary Party and the requesting Primary Party shall pay all reasonable expenses of the non-requesting Primary Party in connection therewith, and (ii) neither Primary Party shall be required to provide the other Party access to, or copies of any of its Tax records.

        Notwithstanding the foregoing, the Primary Parties shall have no obligation to enter into any of the agreements described in this Section 5.25 unless each of them are satisfied, in their sole and absolute discretion with the terms thereof and it shall not be a breach of this Agreement to fail to enter into such agreements before, on or after the Closing Date; provided however, that the Parties acknowledge that the failure to enter into any such Agreement shall not be deemed a failure of any condition precedent to any Party’s obligations hereunder.

For the avoidance of doubt, if the Purchaser makes an election under this Section 5.32 with respect to any Excluded Other Seller, the provisions of Section 2.2.3 shall not apply to such Excluded Other Seller. Upon designation of any Excluded Other Seller, the assets, interests and rights of such Excluded Other Seller shall be Excluded Assets and any Liabilities of such Excluded Other Seller or otherwise relating to such Excluded Assets 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 each Excluded Other Seller shall remain bound by the provisions of Article XI.

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. If a TSA Seller becomes an Excluded Other Seller pursuant to this Section 5.32, 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 to provide, all Services (as defined in the Transition Services Agreement). 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 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 was 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 Subcontract Agreement that it enters into pursuant to Section 5.15(c) 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 5.33. Authorization of Shares. The Purchaser will, at all times, duly authorize and reserve for issuance the Shares.

          SECTION 5.34. Patent Assignments. Prior to the Closing Date, the Purchaser shall notify the Sellers in writing of any defects in title affecting any of the transferred Patents and the Sellers shall take, as soon as reasonably practicable thereafter, all reasonable steps necessary to ensure that NNL is the assignee on record in the relevant government registry or patent office, as applicable, for all transferred Patents and to correct all material defects in title affecting any of the transferred Patents that are still in force in the relevant jurisdiction.

          SECTION 5.36. No Vote. The Purchaser will not take any action that would result in a requirement for the approval of shareholders or any securityholders of the Purchaser pursuant to NASDAQ Listing Rule 5635 or require any other action or consent pursuant to any

applicable exchange rules, regulations, interpretations or Laws in connection with the issuance of the Convertible Notes or the Shares upon the conversion thereof.

          SECTION 5.37. Deposit. On or before November 25, 2009, the Purchaser shall deposit Thirty-Eight Million Four Hundred Fifty Thousand dollars ($38,450,000) (the “Deposit Amount”) with Citibank, N.A.

Notwithstanding anything to the contrary set forth herein or the Deposit Escrow Agreement, the Deposit Amount shall not become a part of the Sellers’ or the EMEA Sellers’ estate until such time as the Deposit Escrow Agent receives joint written instructions from the Parties and Nortel Networks UK Limited instructing the Deposit Escrow Agent to disburse the Deposit Amount to the Distribution Agent or the Main Sellers.

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 are properly imposed upon or payable or collectible or incurred in connection with the purchase by the Purchaser (or a Designated Purchaser) of the Assets under this Agreement and in connection with the other Transaction Documents including, for greater certainty, any stamp, documentary, recording, filing and similar Taxes that may be imposed upon or payable or collectible or incurred in connection with the execution of this Agreement and any other Transaction Documents; provided that if any such Taxes are required to be collected, remitted, or paid by the Sellers or any Subsidiary of the Sellers or any agent thereof (as requested by the Sellers or any Subsidiary of the Sellers), they shall be paid by the Purchaser to the Sellers or any Subsidiary of the Sellers or any such agent, as applicable, at the Closing, as applicable, or thereafter as requested of or by the Sellers. For greater certainty, the Purchaser shall remain liable in respect of any Transfer Taxes for which it is liable under the terms hereof regardless of the date that the Assets purchased under this Agreement are removed by the Purchaser or its agents from the premises of the Sellers or any of the Sellers’ suppliers. Upon request from a Seller, the Purchaser shall provide to such Seller an original receipt (or other such 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(a).

               (b) If the Purchaser or any Designated Purchaser wishes to claim or elect any exemption relating to, or a reduced rate of, Transfer Taxes, in connection with this Agreement or the other Transaction Documents (other than the EMEA Asset Sale Agreement, with respect to which Transfer Taxes are separately addressed therein), the Purchaser or any Designated Purchaser, as the case may be, acting reasonably and in good faith, shall be solely responsible for determining that such exemption, reduction or election (a “Transfer Tax Reduction Determination”) applies. In such case, the Purchaser or the Designated Purchaser, as the case may be, shall provide the Sellers prior to Closing with its permit number, GST 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 by the Purchaser or such Designated Purchaser, as the case may be, it being understood that Purchaser shall remain responsible for any Transfer Taxes whether or not shown due on such Tax Return and shall indemnify and hold harmless the Sellers and their respective officers and directors from any Losses arising out of or resulting from the Transfer Tax Reduction Determination, including without limitation, any Tax, interest, penalty or sanction. The Sellers shall, if applicable, agree to make a joint election under Section 167 of the Excise Tax Act (Canada) and other similar Canadian provincial sales tax elections. If the Purchaser or any Designated Purchaser pays any Transfer Taxes pursuant to this Section 6.1 and a Seller thereafter becomes entitled to a refund for, or a reduction in Liability for, Transfer Taxes payable by such Seller in respect of such Transfer Taxes paid by the Purchaser or a Designated Purchaser, then such Seller shall promptly reimburse the Purchaser or Designated Purchaser for an amount equal to such refund or reduction (including any interest paid in connection with such refund or reduction and net of reasonable out of pocket expenses incurred in obtaining such refund or reduction).

               (c) Each of the Sellers shall cooperate with the Purchaser and its Affiliates in complying with the reporting requirements relating to any Transfer Taxes under applicable Law with respect to this Agreement and the Transaction Documents, and shall make reasonable efforts to cooperate to the extent necessary to obtain any exemption from, or any reduction in amount or rate of, Transfer Taxes sought by Purchaser or any Designated Purchaser. For the avoidance of doubt, such cooperation shall include any applicable Seller using reasonable efforts to obtain and/or furnish to the Purchaser or any Designated Purchaser any applicable information that is reasonably requested by Purchaser or any Designated Purchaser in connection with its efforts to obtain any exemption or reduction in amount or rate of Transfer Taxes, including through the provision of invoices, receipts or other documentation requested by Purchaser or any Designated Purchaser to document the payment of or establish the entitlement to a recovery or refund of, such Transfer Taxes or the eligibility of the transactions to qualify as a “transfer of a going concern” under applicable Law. Each Seller that is required by Law to collect VAT in connection with this Agreement and the Transaction Documents shall, prior to and on the Closing Date, be registered for VAT purposes in any jurisdiction applicable to such Seller.

               (d) Each Tax Return with respect to Transfer Taxes (a “Transfer Tax Return”) imposed upon or payable or collectible or incurred in connection with the purchase by the Purchaser (or a Designated Purchaser) of the Assets under this Agreement

shall be prepared by the Party that customarily has primary responsibility for filing such Transfer Tax Return pursuant to applicable Law. Any Transfer Tax Returns prepared by the Sellers pursuant to this Section 6.1(d) shall be made available to the Purchaser at least five (5) Business Days before such Tax Returns are due to be filed. The Purchaser shall be entitled to review and comment on any Transfer Tax Return prepared by the Sellers prior to making any payment in respect thereof, and the Sellers shall incorporate any reasonable comments received from Purchaser at least three (3) Business Days before such Tax Returns are due to be filed, it being understood that the Purchaser shall remain responsible for any Transfer Taxes whether or not shown due on such Tax Return. Subject to Section 6.1(a), the Purchaser shall pay to the Sellers the amount of any Transfer Taxes payable in respect of Transfer Tax Returns to be filed by the Sellers pursuant to this Section 6.1(d) at least one (1) Business Day before such Transfer Tax becomes due and payable.

               (e) With respect to any provision of this Article VI that by its terms applies to another Transaction Document, such provision shall not apply to the other Transaction Document to the extent that such other Transaction Document contains a contrary provision or contains a provision that is inconsistent with the relevant provision of this Article VI. A reference to a Transaction Document in this Article VI shall not include the EMEA Asset Sale Agreement or the schedules thereto.

          SECTION 6.2. Withholding Taxes. Subject to Section 2.4, the Purchasers and Designated Purchasers shall be entitled to deduct and withhold from the Purchase Price and other payments made under this Agreement and the Transaction Documents (other than the Transition Services Agreement, with respect to which withholding Taxes are separately addressed therein) such amounts as the Purchaser or Designated Purchasers, as the case may be, are required to deduct and withhold under the Code or under 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 Transaction Documents as having been paid to the relevant Seller in respect of whom such deduction and withholding was made by such Purchaser or Designated Purchaser. If any of the Parties learns of any obligation to deduct and withhold from the Purchase Price and other payments made under this Agreement or the Transaction Documents (other than the Transition Services Agreement, with respect to which withholding Taxes are separately addressed therein) 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 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. In connection therewith, the Parties shall cooperate to obtain any applicable forms, certificates, or other documentation or information that is reasonably requested by a Party to obtain any exemption from, or reduced rate of, withholding on any payments made pursuant to this Agreement and the other Transaction Documents.

          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 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 Main 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 (excluding the EMEA Business), in each case, 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 of any kind relating to the Assets or the conduct or operation of the Business (excluding the EMEA Business) for all Tax periods or portions thereof beginning after the Closing Date. The Sellers shall pay, when due, all Taxes apportioned to the Sellers under this Section 6.4(a) that could result in a liability of a Purchaser or Designated Purchaser as a successor or transferee or a Lien on any of the Assets in the hands of the Purchaser or Designated Purchaser. For purposes of the preceding sentence, a Tax shall be considered due when required to be paid after assessment (it being understood that Sellers shall have the right to pursue any action for reconsideration or appeal that under applicable law tolls the time for the payment of the disputed Tax and prevents the Tax Authority from availing itself of its collection remedies); provided that no Tax shall be considered due for purposes of this subsection to the extent payment thereof is excused under applicable Bankruptcy Law.

               (b)

     (i) 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 (excluding the EMEA Business) 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 portions of a Straddle Period in the following manner: (a) in the case of a Tax imposed in respect of property (excluding, for the avoidance of doubt, any income Tax) and that applies rateably 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 (b) 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.

     (ii) In the case where the parties do not file their own separate Tax Return for any Straddle Period under applicable Law, the party legally obligated to file any Tax Return for a Straddle Period (the “Filing Party”) shall timely and accurately prepare and file such Tax Return and timely pay all Taxes due and payable on such Tax Return. Promptly upon the filing of any Tax Return for a Straddle Period, the party filing such Tax Return shall provide a copy of such Tax

Return to the Purchaser or Sellers, as the case may be, of the Assets to which such Tax Return relates, (the “Non-Filing Party”) along with a calculation of the allocation of the Taxes shown to be due on such Tax Return between the Filing Party and the Non-Filing Party pursuant to this Section 6.4(b). Within ten (10) Business Days of the receipt of such Tax Return, the Non-Filing party shall, unless it timely objects to the calculation of the apportioned Tax based upon the principles set forth in this Section 6.4(b), pay to the Filing Party the amount shown in the calculation to be due by the Non-Filing Party. If the Non-Filing Party objects to the calculation of the apportioned Tax as prepared by the Filing Party in writing within ten (10) Business Days of the receipt of such Tax Return, the Filing Party and the Non-Filing Party shall negotiate in good faith a resolution of the calculation and the Non-Filing Party shall promptly pay to the Filing Party the amount of the apportioned Tax as finally resolved. If after five (5) Business Days of negotiation, the Parties cannot agree upon the apportioned Tax amount, they shall promptly submit the matter to the Accounting Arbitrator for final resolution as promptly as practical and the Accounting Arbitrator’s decision shall be final and binding upon the Parties as to the amount of any disputed apportioned Tax, and the Non-Filing Party shall promptly pay to the Filing Party the amount of the disputed apportioned Tax as determined by the Accounting Arbitrator. The costs of the Accounting Arbitrator shall be borne by the Party whose position is less correct in the judgment of the Accounting Arbitrator.

               (c) Prior to, on and after the Closing Date, each of the Sellers shall reasonably cooperate with the Purchaser and its Affiliates (i) to obtain any applicable forms, certificates, or other information and (ii) to comply with clearance procedures established under applicable Law in the jurisdictions in which the Assets are being transferred hereunder to establish, quantify, reduce or eliminate the extent to which the Purchaser or any Designated Purchaser could be liable for any Taxes of the Sellers that are Excluded Liabilities, including by reason of a Lien being filed on the Assets or as a result of such Purchaser or Designated Purchaser having liability as a transferee or successor under applicable Law; provided that such cooperation shall not include a liquidation or restructuring of a Seller or any business of a Seller, and provided further that such cooperation would not: (i) in the Sellers’ opinion, acting reasonably and in good faith, result in the imposition on the Sellers of any director’s or officer’s liability or Tax liability (other than any amount necessary to pay any Taxes of the Sellers that are Excluded Liabilities that Sellers are required to pay (as being due) under Section 6.4(a) at the time such cooperation is provided and any interest, penalties and additions to Tax thereon) that is not fully and promptly reimbursed by the Purchaser and its Affiliates; or (ii) cause any of the Sellers to bear any other out-of-pocket cost or expense that is not fully and promptly reimbursed by the Purchaser and its Affiliates; and provided further that such cooperation would not violate applicable Law, including Bankruptcy Laws as applied to the relevant Seller(s) and any order or other legal obligation of a Seller arising out of the Bankruptcy Proceedings. For the avoidance of doubt, such cooperation shall include taking actions necessary to comply with Tax clearance procedures established under applicable Law in Argentina and Hong Kong.

          SECTION 6.5. Tax Records.

               (a) Notwithstanding the provisions of Section 5.6(a), Section 5.23 and Section 5.24, but subject to the provisions of Section 5.6(e) (i) after the date of the Auction, the Purchaser and the Designated Purchasers, on the one hand, and the Sellers, on the other hand, will make available to the other, as reasonably requested, and to any Tax Authority, all information, records or documents relating to Taxes with respect to the Assets, Assumed Liabilities or the Business (excluding the EMEA Business) for all periods prior to and 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 reasonably needs access to the records in the possession of a second party relating to the Assets, Assumed Liabilities or the Business (excluding the EMEA Business) for purposes of preparing Tax Returns or complying with any Tax audit request, subpoena or any 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 and 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 6.5(a) 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 Main Sellers. 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 Nortel Networks Technology Corporation (“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 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).

          SECTION 6.6. Cooperation.

               (a) The Sellers and the Purchaser shall reasonably cooperate with each other in connection with the conduct of any Tax audit, investigation, dispute, or appeal relating to any Pre-Closing Taxable Period.

               (b) Notwithstanding the provisions of Section 5.6, but subject to the provisions of Section 5.6(e) and, solely with respect to the subject matter addressed therein, subject to Section 6.5(a), from and after the date hereof through the Closing Date, (i) the Sellers shall reasonably cooperate with the Purchaser and its Affiliates to develop and provide such information as is reasonably requested and reasonably necessary to permit the Purchaser and its Affiliates to identify and timely comply with their respective obligations under applicable Tax Laws arising out of this Agreement and the other Transaction Documents and (ii) the Sellers shall reasonably cooperate with the Purchaser and its Affiliates to structure and carry out the transactions between the Sellers, on the one hand, and the Purchaser and its Affiliates, on the other hand, contemplated by this Agreement and the other Transaction Documents in a tax-efficient manner (including, without limitation, to limit withholding Taxes and irrecoverable VAT with respect to the transactions contemplated by this Agreement and the Transaction Documents); provided that any such cooperation to be provided in (i) and (ii) above would not include a liquidation or restructuring of a Seller or any business of a Seller, would not result in the imposition on any Seller of any additional Tax Liability or cause any Seller to bear any additional out-of-pocket cost or expense, in each case which is not fully and promptly reimbursed by the Purchaser and its Affiliates and such cooperation would not violate applicable law, including Bankruptcy Laws as applicable to the relevant Seller(s) and any order or other legal obligation of a Seller arising out of the Bankruptcy Proceedings

          SECTION 6.7. North American Tax Escrow.

               (a) In the event that any Tax Authority shall (A) make any claim against any Purchaser, Designated Purchaser, or any of their Affiliates (a “Purchaser Party”) for any Taxes that are Excluded Liabilities of any Seller or (B) have in its favor a Lien on any of the Assets arising out of the non-payment of any Taxes that are Excluded Liabilities of a Seller (any Taxes described in (A) and (B) above hereby are referred to collectively as “Excluded Taxes”), such Purchaser Party shall be entitled to recover all Losses arising out of or in connection with such Excluded Taxes promptly (in accordance with the following provisions) by obtaining cash from the Tax Escrow Amount in an amount equal to the aggregate amount of such Losses, provided that (i) the aggregate amount to be recovered under this Section 6.7 in respect of such Losses shall not exceed the Tax Escrow Amount (plus any accrued interest on the Tax Escrow Amount); and (ii) the only Losses recoverable under this Section 6.7 shall be Losses incurred by a Purchaser Party after the earlier of the

date on which a Tax Authority has made a claim described in (A) above or registered or imposed a Lien described in (B) above, as applicable.

               (b) If a claim for Losses under Section 6.7(a) (a “Tax Claim”) is to be made by a Purchaser Party, the Purchaser shall give written notice (a “Claim Notice”) on behalf of such Purchaser Party to the Main Sellers promptly after such Purchaser Party becomes aware that a Tax Authority has made a claim against it for any Excluded Taxes or that such Taxes have given rise to a Lien described in clause (B) of subsection (a) above, as applicable, stating, with reasonable specificity, the basis for the Tax Claim, and including a copy of all relevant documents received from the relevant Tax Authority. In the event that any Purchaser Party is entitled to recover the amount of any such Losses from the Tax Escrow Amount, the Purchaser and the Main Sellers shall issue joint written instructions to the Escrow Agent authorizing distribution of the amount of such Losses to such Purchaser Party and such Purchaser Party shall be responsible for paying over to the relevant Tax Authority the amount of Excluded Taxes distributed to it from the Tax Escrow Amount to the extent it has not already done so at the time of the distribution of such amount from such fund and shall provide Sellers with such written evidence as is reasonably requested in writing to confirm that payment to the relevant Tax Authority has been duly made.

               (c) Upon delivery by the Sellers to the Purchaser prior to Closing of a certificate or other documentation issued by the Hong Kong Inland Revenue Department reasonably satisfactory in form and content to the Purchaser confirming that Nortel Networks (Asia) Limited has no outstanding Tax Liabilities, the Tax Escrow Amount payable on Closing to the Escrow Agent shall be reduced by $5,000,000.

               (d) Upon delivery by the Sellers to the Purchaser after Closing of a certificate or other documentation issued by the Hong Kong Inland Revenue Department reasonably satisfactory in form and content to the Purchaser confirming that Nortel Networks (Asia) Limited has no outstanding tax liabilities, and provided that a Purchaser Party has not served a valid Claim Notice to the Main Sellers before that time in respect of a Tax Claim relating to Excluded Taxes of Nortel Networks (Asia) Limited, the Purchaser and the Main Sellers shall deliver to the Escrow Agent joint written instructions to release to the Distribution Agent, on behalf of the Sellers and the EMEA Sellers, $5,000,000 out of the Tax Escrow Amount (or such lesser amount remaining therein at that time).

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

               (f) In the event that a Claim Notice is served, the Purchaser shall take such steps as are commercially reasonable to mitigate or otherwise defend the assessment(s) made by the relevant Tax Authority. In the event that a payment is made to a Purchaser Party pursuant to this Section 6.7, and subsequently a Purchaser Party becomes entitled to and receives a refund of Excluded Taxes (in whole or in part), then the Purchaser shall, or shall cause the relevant Purchaser Party to, promptly pay to the Distribution Agent, on behalf of the Sellers and the EMEA Sellers, an amount equal to such refund (including any interest paid in connection with such refund), net of reasonable out-of-pocket expenses incurred by the Purchaser Party in obtaining such refund, unless (i) such refund is received prior to the third anniversary of the Closing Date or (ii) at the time the refund is received, the Tax Escrow Amount is less than the sum of the Tax Claims that are evidenced by one or more Claim Notices and which remain pending and unresolved on such date, then, in each case, the Purchaser Party shall pay the net amount of such refund to the Escrow Agent to be added to the Tax Escrow Amount.

               (g) Notwithstanding anything to the contrary in this Agreement (including, without limitation, the provisions of Section 11.1 of this Agreement as applied to provisions other than those contained in this Article VI), recourse to the Tax Escrow Amount under this Section 6.7 shall be the sole and exclusive remedy available to the Purchaser and any Designated Purchaser following the Closing in respect of any liability for Taxes that are Excluded Liabilities of a Seller or any liability for Taxes that give rise to any Lien on any Assets.

          SECTION 6.8. EMEA Tax Escrow.

               (a) In the event that any Tax Authority shall make any claim against Purchaser or any EMEA Designated Purchaser or any of their Affiliates (an “EMEA Purchaser Party”) for (A) any Taxes that are EMEA Excluded Liabilities of any EMEA Seller or (B) any Succession Tax Liabilities or (C) any Succession Tax Lien (any Taxes described in (A) and (B) and (C) above hereby are referred to collectively as “EMEA Excluded Taxes”), such EMEA Purchaser Party shall be entitled to recover all Losses arising out of or in connection with such EMEA Excluded Taxes promptly (in accordance with the following provisions) by obtaining cash from the EMEA Tax Escrow Amount in an amount equal to the aggregate amount of such Losses, provided that: (i) the aggregate amount to be recovered under this Section 6.8 in respect of such Losses shall not exceed the EMEA Tax Escrow Amount (plus any accrued interest on the EMEA Tax Escrow Amount); (ii) the only Losses recoverable under this Section 6.8 shall be Losses incurred by an EMEA Purchaser Party after a Tax Authority has made a claim described in (A), (B) or (C) above, as applicable; and (iii) no claim shall be allowed by any EMEA Purchaser Party in respect of Italian Excluded Taxes other than pursuant to Section 6.9 below.

               (b) If a claim for Losses under subsection (a) (an “EMEA Tax Claim”) is to be made by an EMEA Purchaser Party, the Purchaser shall give written notice (an “EMEA Tax Claim Notice”) on behalf of such EMEA Purchaser Party to the Joint Administrators promptly after such EMEA Purchaser Party becomes aware that a Tax Authority has made a claim against it for any EMEA Excluded Taxes or that such Taxes have given rise to any Succession Tax Lien for which recovery is sought under this Section 6.8, stating, with reasonable specificity, the basis for the EMEA Tax Claim and the amount

of EMEA Excluded Taxes claimed, and including a copy of all relevant documents received from the relevant Tax Authority. In the event that any EMEA Purchaser Party is entitled to recover the amount of any such Losses from the EMEA Tax Escrow Amount, the Purchaser and the Joint Administrators shall issue joint written instructions to the Escrow Agent authorizing distribution of the amount of such Loss to such EMEA Purchaser Party and such EMEA Purchaser Party shall be responsible for paying over to the relevant Tax Authority the amount of such EMEA Excluded Taxes distributed to it from the EMEA Tax Escrow Amount to the extent it has not already done so at the time of the distribution of such amount from such fund, and shall provide the Joint Administrators with such written evidence as is reasonably requested in writing to confirm that payment to the relevant Tax Authority has been duly made.

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

          (d) In the event that an EMEA Claim Notice is served, the Purchaser shall take such steps as are commercially reasonable to mitigate or otherwise defend the assessment(s) made by the relevant Tax Authority. In the event that a payment is made to an EMEA Purchaser Party pursuant to this Section 6.8, and subsequently an EMEA Purchaser Party or any Affiliate becomes entitled to and receives a refund of amounts in respect of EMEA Excluded Taxes, then the Purchaser shall or shall procure that the relevant EMEA Purchaser Party shall promptly pay to Distribution Agent, on behalf of the Sellers and EMEA Sellers, an amount equal to such refund (including any interest paid in connection with such refund), net of reasonable out-of-pocket expenses incurred by the EMEA Purchaser Party in obtaining such refund, unless (i) such refund is received prior to the third anniversary of the Closing Date or (ii) at the time the refund is received, the EMEA Tax Escrow Amount is less than the sum of the EMEA Tax Claims that are evidenced by one or more EMEA Tax Claim Notices and which remain pending and unresolved on such date, then, in each case, the Purchaser Party shall pay the net amount of such refund to the Escrow Agent to be added to the EMEA Tax Escrow Amount.

          SECTION 6.9. Italian Tax Escrow.

          (a) In the event that any Tax Authority in Italy shall make any claim against the Purchaser or any EMEA Designated Purchaser or any of their Affiliates (an “Italian Purchaser Party”) for (A) any Taxes that are EMEA Excluded Liabilities of any EMEA Seller or (B) any Succession Tax Liabilities or (C) any Succession Tax Lien (any such Taxes are hereby are referred as “Italian Excluded Taxes”), such Italian Purchaser

Party shall be entitled to recover all Losses arising out of or in connection with such Italian Excluded Taxes promptly (in accordance with the following provisions) by obtaining cash from the Italian Tax Escrow Amount in an amount equal to the aggregate amount of such Losses, provided that: (i) the aggregate amount to be recovered under this Section 6.9 in respect of such Losses shall not exceed the Italian Tax Escrow Amount (plus any accrued interest on the Italian Tax Escrow Amount); and (ii) the only Losses recoverable under this Section 6.9 shall be Losses incurred by an Italian Purchaser Party after a Tax Authority in Italy has made a claim.

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

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

          (d) In the event that an Italian Claim Notice is served, the Purchaser shall take such steps as are commercially reasonable to mitigate or otherwise defend the assessment(s) made by the relevant Tax Authority. In the event that a payment is made to an Italian Purchaser Party pursuant to this Section 6.9, and subsequently an Italian Purchaser Party or any Affiliate becomes entitled to and receives a refund of amounts in respect of Italian Excluded Taxes, then the Purchaser shall or shall procure that the relevant Italian Purchaser Party shall promptly pay to Distribution Agent, on behalf of the Sellers and

EMEA Sellers, an amount equal to such refund (including any interest paid in connection with such refund), net of reasonable out-of-pocket expenses incurred by the Italian Purchaser Party in obtaining such refund, unless (i) such refund is received prior to the third anniversary of the Closing Date (other than where, prior to such refund being received, the provisions at Section 6.9(f) have applied) or (ii) at the time the refund is received, the Italian Tax Escrow Amount is less than the sum of the Italian Tax Claims that are evidenced by one or more Italian Tax Claim Notices and which remain pending and unresolved on such date, then, in each case, the Purchaser Party shall pay the net amount of such refund to the Escrow Agent to be added to the Italian Tax Escrow Amount.

          (e) Upon delivery by Nortel Italy to the Purchaser prior to Closing of a certificate, ruling or other documentation issued by the Tax Authorities in Italy (including but not limited to a response to the Interpellation addressed to the regional department of the Revenue Office of Lombardy as submitted by Nortel Italy on 4 August 2009) reasonably satisfactory in form and content to the Purchaser (acting in good faith), and, if such certificate, ruling or other documentation does not address Succession Tax Liens, such other written evidence as is reasonably satisfactory in form and content to the Purchaser (acting in good faith) addressing Succession Tax Liens, together confirming either:

     (i) that Nortel Italy does not have any liabilities for Tax that could become Succession Tax Liabilities or Succession Tax Liens; or

     (ii) that it is not possible (whether as a result of Bankruptcy Proceedings or otherwise) for liabilities for Tax of Nortel Italy to become Succession Tax Liabilities or Succession Tax Liens,

then the Italian Escrow Amount payable on Closing to the Escrow Agent shall be reduced to nil.

          (f) Upon delivery by Nortel Italy to the Purchaser after Closing of a certificate, ruling or other documentation issued by the Tax Authorities in Italy (including but not limited to a response to the Interpellation addressed to the regional department of the Revenue Office of Lombardy as submitted by Nortel Italy on 4 August 2009) reasonably satisfactory in form and content to the Purchaser (acting in good faith) and, if such certificate, ruling or other documentation does not address Succession Tax Liens, such other written evidence as is reasonably satisfactory in form and content to the Purchaser (acting in good faith) addressing Succession Tax Liens, together confirming either:

     (i) that Nortel Italy does not have any liabilities for Tax that could become Succession Tax Liabilities or Succession Tax Liens; or

     (ii) that it is not possible (whether as a result of Bankruptcy Proceedings or otherwise) for liabilities for Tax of Nortel Italy to become Succession Tax Liabilities or Succession Tax Liens,

then the Purchaser and Joint Administrators shall deliver to the Escrow Agent joint written instructions to release to the Distribution Agent, on behalf of the Sellers and the EMEA Sellers, any remaining portion of the Italian Tax Escrow Amount (including any accrued

interest thereon) in excess of an amount equal to the aggregate of all Italian Tax Claims which have been asserted prior to such date evidenced by one or more Italian Tax Claim Notices and which remain pending and unresolved on such date, provided that as soon as reasonably practicable after the final resolution of each such Italian Tax Claim, the Purchaser and the Joint Administrators shall issue joint written instructions to the Escrow Agent to release to the Distribution Agent, on behalf of the Sellers and EMEA Sellers, the remaining portion of the Italian Tax Escrow Amount referable to that Italian Tax Claim (including any accrued interest thereon).

ARTICLE VII
EMPLOYMENT MATTERS

          SECTION 7.1. Employment Obligations with Respect to Non-Union Employees.

            Except for the provisions of Section 7.1.1(a) and the first three (3) sentences of Section 7.1.2(b)(ii)(B), the provisions of this Section 7.1 shall apply only with respect to Non-Union Employees. Subject to the clarificatory wording in 7.1.1(a) and the provisions relating to the Closing Accrued Vacation and Service Award Amount, the Excess ARD Employees Amount and the Closing Retirement Obligation Amount, the provisions of this Agreement shall not apply to EMEA Employees.

7.1.1. Employment Terms.

                 (a) Within thirty (30) days following the completion of the Auction, the Purchaser shall notify the Sellers of the identity of the Employees on Section 4.10(b) of the Sellers Disclosure Schedule by unique identifier (the “Identified Employees”) to whom the Purchaser or a Designated Purchaser intends to provide a written offer of employment or notice of continued employment in accordance with applicable Law (each an “Offer” and collectively, the “Offers”); provided that, promptly after the date hereof, the relevant Sellers have permitted the Purchaser with access to such information as the Purchaser reasonably requires in accordance with Section 5.6(d) and Section 7.4(c) in order to make such identifications (except as prohibited by Law). As soon as reasonably practicable following the latest of the granting of the U.S. Sale Order and the Canadian Approval and Vesting Order, but in any event no later than the time required to provide the Offer Consideration Period described below, the Purchaser shall, or shall cause a Designated Purchaser to, extend a minimum of Two Thousand (2,000) Offers, which number shall include all EMEA Transferring Employees, whose employment shall be governed by the EMEA Asset Sale Agreement (for the avoidance of doubt, no Offers will be required to be made to ARD Transferring Employees whose contracts of employment will transfer to the Purchaser by operation of Law, but the number of EMEA Transferring Employees will be included within the minimum number set forth above, and the terms of Offers made to Non-ARD Transferring Employees will be governed by the EMEA Asset Sale Agreement), plus a sufficient number of Employees equal to, in total, such minimum number, with employment of such Employee who is not an EMEA Employee to take effect as of the Effective Hire Date, as defined below. Such Offers to Employees (who are not EMEA Employees) shall be contingent (i) in the discretion of the Purchaser, on each such Employee passing a background check and, if such Employee is located in the United States, drug screening, in all cases, to the extent permitted and consistent with applicable Law and except with respect

to Union Employees, and (ii) in the case of Inactive Employees, upon their return to active status (other than Employees set forth on Section 7.1.1(a) of the Sellers Disclosure Schedule whose employment transfers automatically by operation of Law to the Purchaser or a Designated Purchaser) with the Purchaser or one of its Affiliates within two (2) years following the date of the commencement of the leave or such longer period as provided under applicable Law. The Offers shall be made prior to the Closing in compliance with Section 7.1.1 and shall provide each such Employee with a consideration period prior to the Closing that is no less than two (2) weeks with respect to Employees located in Japan and with respect to Employees located in other countries, one week, or such longer period as required by applicable Law (the “Offer Consideration Period”). The Sellers shall have the right to review any form Offer with respect to a particular jurisdiction (and any Offer that deviates in any material respect from the form Offer with respect to the relevant country) made pursuant to Section 7.1.1 prior to it being sent to any Employee. As soon as reasonably practicable following the Sellers’ receipt from the Purchaser of the notice containing the Identified Employees (as required pursuant to the first sentence of this Section 7.1.1(a)) but in all events prior to Closing, the Sellers shall take any and all action permitted under applicable Law legally necessary to cause the termination of employment, effective prior to the Closing, of each Employee set forth on Section 4.10(b) who is not an Identified Employee but only to the extent such employment would otherwise transfer to the Purchaser or a Designated Purchaser by operation of Law.

          (b) For Employees employed in Canada and the United States, the Offers shall be in accordance with applicable Law and provide terms and conditions of employment as of such Employee’s Effective Hire Date that will consist of (i) either the same annual base salary (whether on a salary, wage or hourly rate basis) and annual incentive plan target amount for such Employee as set out in the Employee Information or a substantially comparable overall compensation package (taking into account any equity-based compensation that may be offered by Purchaser or its Affiliates to such Employee) to such annual base salary and annual incentive plan target amount set out in the Employee Information, (ii) a location of employment reasonably close to such Employee’s current location as set out in the Employee Information, and (iii) employee benefits that are substantially comparable in the aggregate to (A) employee benefits received by such Employee from the Sellers as of the date hereof or (B) employee benefits provided by the Purchaser (or any of its Affiliates) to its similarly situated employees.

          (c) For all Employees set forth in Section 4.10(b) of the Sellers Disclosure Schedule (other than Employees in Canada and the United States) in any country set forth on Section 7.1.1(c) of the Seller Disclosure Schedule where the number of Employees in such country is ten (10) or more, the Purchaser’s Offer to Employees in such country shall be in accordance with applicable Law and on terms and conditions not less favorable in the aggregate than those terms and conditions received by the Employees as of the date hereof as disclosed in Section 4.10(a) and Section 4.10(b) of the Sellers Disclosure Schedule, subject to certain adjustments to conform to the Purchaser’s (or its Affiliates’) standard employment policies where legally possible; provided, that, following the Employee Transfer Date, nothing shall prohibit the Purchaser or any Designated Purchaser from making changes to such terms and conditions of employment that are generally applicable and broadly based across the Purchaser’s or Designated Purchaser’s employee

population in the particular country; provided, further that in no event other than as required by applicable Law, shall the Purchaser or a Designated Purchaser be required to (i) provide defined benefit pension plans, or (ii) take into account defined benefit pension benefits, post retirement health and welfare benefits, severance or retention, the KEIP or KERP, equity compensation, non-qualified deferred compensation plans, non-qualified retirement plans or retirement allowance plans of the Sellers or any of their Affiliates when determining whether terms and conditions of employment are no less favorable in the aggregate.

          (d) For Employees other than Employees referred to in Section 7.1.1(b) or Section 7.1.1(c), the Purchaser’s Offer to such Employee shall be in accordance with applicable Law and on such terms and conditions of employment reasonably competitive with those received by similarly situated employees in the local market.

          (e) Employees whose employment transfers automatically by operation of Law to the Purchaser or a Designated Purchaser will have their terms and conditions of employment governed by such applicable Laws, but at a minimum shall receive terms and conditions of employment that are no less favorable than those employees in Section 7.1.1(c) or Section 7.1.1(d), as applicable, based on the number of the Sellers’ Employees in the country where such Employees are employed, except with respect to Employees located in the Province of Quebec, Canada, as indicated in the Employee Information, who shall be treated in accordance with 7.1.1(b).

          (f) Any Employee who accepts an Offer and commences employment with the Purchaser or a Designated Purchaser pursuant to this Agreement, and any Employees whose employment transfers by operation of Law, shall each be deemed to be a Transferred Employee for all purposes of this Agreement. Inactive Employees shall remain employed by the relevant Seller until their release in the Ordinary Course to return to active status with the Purchaser or one of its Affiliates within two (2) years following the date of the commencement of the leave or such longer period as provided under applicable Law. Visa Employees and Seconded Employees shall remain employed by the relevant Seller under the terms and conditions of the Loaned Employee Agreement. The Purchaser or a Designated Purchaser shall use commercially reasonable efforts beginning immediately after the date of the Auction to obtain, prior to the Closing Date, and beyond if necessary, at Purchaser’s cost, such visas or permits as are required for Purchaser or a Designated Purchaser to employ any Visa Employee who accepts an Offer effective as of the Effective Hire Date. The Purchaser or Designated Purchaser shall use commercially reasonable efforts beginning promptly following the notification to Sellers of the Identified Employees (as provided for in Section 7.1.1(a)) to resolve, as soon as reasonably practicable following such notification, at the Purchaser’s cost, any impediments to Purchaser’s or Designated Purchaser’s employment of Employees in countries set forth in Section 1.1(m) of the Sellers Disclosure Schedule.

          (g) The Effective Hire Date for Employees is (i) the Employee Transfer Date for those Employees other than Inactive Employees, Seconded Employees and Visa Employees, (ii) 12:01 a.m. on the first Business Day following the release to return to active employment from leave for all Inactive Employees and (iii) the date specified in the Loaned Employee Agreement with respect to Visa Employees and Seconded Employees, as applicable. As of the Effective Hire Date and, except as otherwise provided herein, for a

period of not less than twelve (12) months after the Closing Date, the employment of Non-Union Employees shall be, at a minimum, on the terms and conditions set forth in Section 7.1.

          (h) With respect to all Employees (other than EMEA Employees and Union Employees) to whom the Purchaser extends an Offer pursuant to Section 7.1.1 but who do not accept or who reject such an Offer (each, a “Rejecting Employee”), the Purchaser shall reimburse the Sellers for payments made by Sellers in an aggregate amount up to $2,000,000 in respect of pay in lieu of notice (including WARN Act notice) and/or severance liability relating to such Rejecting Employees (the “Rejecting Employees Liability Limit”); provided that any such payments shall have been made by the Sellers as required by applicable Law or the Seller Employee Plans listed in Section 4.10(a)(i) of the Sellers Disclosure Schedule or pursuant to a Contract in effect as of the date hereof, and a copy of which will be delivered to the Purchaser at the time such liability is incurred. Notwithstanding anything to the contrary in this Agreement, the Sellers shall retain, and neither the Purchaser nor any of its Affiliates shall assume any Liability whatsoever related to or arising from the Rejecting Employees in respect of pay in lieu of notice (including WARN Act notice) and/or severance liability, including without limitations, any Liability relating to or arising from Claims with respect to a change in the terms of employment made with respect to any Rejecting Employee in the Province of Quebec) to the extent such Liabilities exceed the Rejecting Employees Liability Limit.

7.1.2. Employee Benefits.

          (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 for all purposes other than benefit accrual under any defined benefit pension plan, and except as would result in a duplication of benefits.

          (b) 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 severance payments and severance benefits that are substantially similar to the severance payments and severance benefits provided to similarly situated employees of the Purchaser or the Designated Purchaser.

     (ii)

     (A) The Sellers shall pay the amount of compensation with respect to the accrued and unused vacation hours that is due and owing to the Transferred Employees (other than Transferred Employees whose accrued and unused vacation is specified in Section 7.1.2(b)(ii)(B) of the Sellers Disclosure Schedule (the “Specified Transferred Employees”)), up to their Effective Hire Date, to such Transferred Employees by the date required under applicable Law. The

Purchaser will, and will cause the relevant Designated Purchasers to, make commercially reasonable 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.

     (B) Section 7.1.2(b)(ii)(B) of the Sellers Disclosure Schedule sets forth the amount of accrued and unused vacation hours that are due and owing to the Specified Transferred Employees as of the date hereof and updated by the Sellers as of the Closing Date. The Purchaser shall, or shall cause its relevant Affiliates to, grant each Specified Transferred Employee paid time off in an amount equal to such accrued unused vacation hours for such Specified Transferred Employee as set forth in Section 7.1.2(b)(ii)(B) of the Sellers Disclosure Schedule. If such Specified Transferred Employee terminates employment with the Purchaser or an Affiliate of the Purchaser prior to receiving such paid time off, as described above, the Purchaser shall pay such Specified Transferred Employee an amount equal to any such unused paid time off upon such employment termination. Under the vacation policy of the Purchaser or an Affiliate of the Purchaser, the vacation accrual rate of each Transferred Employee on and after the Effective Hire Date shall be equal to either, in the sole discretion of the Purchaser or its Affiliate, the Transferred Employee’s vacation accrual rate (i) as reflected in the Employee Information or (ii) under the vacation policy of the Purchaser or its relevant Affiliate applicable to similarly situated employees after taking into account such Transferred Employee’s service, if applicable, as provided in Section 7.1.2(a). For the avoidance of doubt, such vacation accrual rate applicable to Specified Transferred Employees shall not be decreased by the Purchaser or its Affiliates as a result of the obligation in this Section 7.1.2(b)(ii)(B) that the Purchaser or its Affiliates grant such Employees accrued and unused vacation hours due and owing as of the Closing Date.

     (iii)

     (A) With respect to each Transferred Employee (and his or her eligible dependents, as applicable) in Canada and the United States, the Purchaser or the relevant Purchaser’s Affiliates shall (x) waive any eligibility periods, evidence of insurability or pre-existing condition limitations and (y) honor any deductibles, co-payments, co-insurance or out-of-pocket expenses paid or incurred by such employee, including with respect to his or her 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 documentation of such expenses paid or incurred to the Purchaser or its Affiliates, and in each case to the extent waived or honored under the Seller Employee Plans in which such Transferred Employee participated immediately prior to the Closing and to the extent doing so will not result in the duplication of benefits.

     (B) With respect to each Transferred Employee (and his or her eligible dependents, as applicable) in all countries other than those described in Section 7.1.2(b)(iii)(A), the Purchaser or the relevant Purchaser’s Affiliates shall use commercially reasonable efforts to cause the Purchaser Employee Plans to (x)

waive any eligibility periods, evidence of insurability or pre-existing condition limitations and (y) honor any deductibles, co-payments, co-insurance or out-of-pocket expenses paid or incurred by such employee, including with respect to his or her 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 documentation of such expenses paid or incurred to the Purchaser or its Affiliates, and in each case to the extent waived or honored under the Seller Employee Plans in which such Transferred Employee participated immediately prior to the Closing and to the extent doing so will not result in the duplication of benefits.

     (iv) The Purchaser or Designated Purchaser shall provide each Transferred Employee employed in Australia, with the benefit of the amount set forth in Section 7.1.2(b)(iv) of the Sellers Disclosure Schedule of long service leave and sick leave, at such time, if any, as payment of such amount is due and owing to each such Transferred Employee under applicable Law, taking into account in the calculation of such total payment due, the service of such Transferred Employee as set forth in the Employee Information together with such Transferred Employee’s service with the Purchaser on and after the Closing Date. Section 7.1.2(b)(iv) of the Sellers Disclosure Schedule shall be updated no later than ten (10) Business Days prior to the Closing Date to reflect additions or deletions of Identified Employees or other status changes that are not prohibited under Section 5.9.

     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 who are Transferred Employees as a successor, assign or purchaser of the relevant Seller. With respect to all Union Employees who are not Identified Employees, the Purchaser shall reimburse the Sellers for payments made by Sellers in respect of severance liability pursuant to the Collective Labor Agreement or as required by applicable Law relating to such Union Employees; provided, that, the Sellers agree to use commercially reasonable efforts to mitigate the Liabilities associated with the termination of such Union Employees by providing, upon notice from the Purchaser identifying any Union Employee who will not be an Identified Employee, working notice to such Union Employees and, in the case of Union Employees located in the province of Quebec, written notice, and the Minister of Employment and Social Solidarity in the case of a mass or group termination in all material respects in accordance with applicable Law.

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

       (a) Liabilities related to the Seller Employee Plans or any employee plans or arrangements related to former employees of the Business (excluding the EMEA Business), including the Sellers’ or any of their Affiliates’ (excluding the EMEA Sellers) or

Seller Employee Plans’ obligations to make payments or provide benefit accrued under any Seller Employee Plan, except with respect to the Specified Employee Liabilities or as specified in the Loaned Employee Agreement;

            (b) 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 the Employees and/or their qualified beneficiaries with respect to a COBRA qualifying event that occurs prior to such Employees’ Effective Hire Date including, for avoidance of doubt, an Employee’s termination of employment from the Sellers or their Affiliates;

            (c) Liabilities related to the stock or other equity interests in the Seller or any of its Affiliates;

            (d) Except with respect to the Assumed Liabilities and as provided for in Article VII, Liabilities relating to (i) any Employee’s or a former employee’s employment or termination of employment with any of the Sellers or their Affiliates, including any severance or similar obligations that may arise as a result of the transfer of an Employee’s employment to the Purchaser or one of its Affiliates or as a result of the Employee’s refusal of the Purchaser’s Offer and any Liabilities that relate to the Inactive Employees’, Visa Employees’ and Seconded Employees’ employment or termination of employment with any of the Sellers or their Affiliates, except as otherwise provided in the Loaned Employee Agreement, (ii) an applicant with respect to potential employment with any of the Sellers or their Affiliates, (iii) the purported class action filed in Ontario Superior Court of Justice under Court file number 08-CV41878CP, (iv) any Action arising on or prior to the Closing filed by any Person in connection with any Employee’s employment or the termination thereof with the Sellers, or (v) any Action arising prior to, on or after the Closing relating to or filed by any of the Employees set forth in Section 4.10(b) who are not Identified Employees in connection with any such Employee’s employment or termination of employment with the Sellers; and

            (e) Any Liabilities with respect to Canadian Union Retirees.

          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 Purchaser shall not, and shall procure that the Designated Purchasers and any of the Purchaser’s Affiliates shall not, issue any announcement or communication to their respective employees or the Employees, prior to consultation with, and the approval of, the Main Sellers (not to be unreasonably withheld or delayed) with respect to this Agreement or any of the transactions contemplated hereby. If requested, the non-requesting Party shall cooperate with the requesting Party in respect of the development and distribution of any announcement and communication to the employees of the Sellers, including Employees, with respect to this Agreement or any of the transactions contemplated hereby.

            (b) The Purchaser undertakes to keep the Employee Data and any additional information provided to the Purchaser by the Sellers with respect to individually

identifiable Employees (collectively, “Employee Data”) in confidence and agrees 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 Data only to such of its employees, agents and advisors as is reasonably necessary for the purposes of complying with its obligations pursuant to this Agreement;

     (ii) the Employee Data 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 shall be returned to the Sellers or destroyed, at the Sellers’ election, if this Agreement is terminated; and

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

          (c) The Purchaser and the Sellers shall cooperate with each other to provide for an orderly transition of the Transferred Employees from the Sellers to the Purchaser or the Designated Purchasers, as applicable (including the providing of any information by the Sellers to the Purchaser as may be reasonably requested by Purchaser for purposes of complying with its obligations pursuant to Article VII), subject to Section 5.6(d), and to minimize the disruption to the respective businesses of the Parties resulting from the transactions contemplated hereby.

          (d) Within sixty (60) days following the relevant Effective Hire Date, except to the extent prohibited by applicable data privacy Laws and subject to consent by such employee to be obtained by the Purchaser or Designated Purchaser in his or her Offer (including any consent, if required, to transfer Employee Records across geographical boundaries), or as otherwise required by Law, the Sellers shall provide the Purchaser or the Designated Purchaser with the Employee Records (or a copy thereof) of Transferred Employees other than those Employee Records that constitute Assets pursuant to Section 2.1.1(h) hereof. Further, after the Effective Hire Date, the Purchaser may request in writing an individual Employee Record in relation to a reasonably contemplated employment termination by the Purchaser and, except to the extent prohibited by applicable data privacy Laws and subject to consent by such employee to be obtained by the Purchaser or Designated Purchaser in his or her Offer (including any consent, if required, to transfer Employee Records across geographical boundaries), the Seller shall provide such individual Employee Record within two (2) Business Days. With respect to such Employee Records provided by the Sellers to the Purchaser or Designated Purchasers, in the event that the Sellers reasonably need access to such records for purposes of complying with a subpoena or in connection with any pending or threatened Action, the Purchaser or Designated Purchaser will allow the Sellers reasonable access to such records for the sole purpose of obtaining information for use as aforesaid and will permit the Sellers to make copies thereof as may be necessary or convenient.

          (e) During the Non-Solicitation Period the Sellers shall not, without the advance written consent of the Purchaser, either directly or indirectly solicit for employment or hire any Transferred Employee unless the employment of such employee is involuntarily terminated by the Purchaser or Designated Purchaser prior to such action by the Sellers; provided, however, that nothing in this Section 7.4(e) shall prevent the Sellers from (i) conducting generalized employment searches, including placing bona fide public advertisements, that are not specifically targeted at such Transferred Employees, or (ii) hiring such Transferred Employees identified through such generalized employment searches.

          (f) During the Non-Solicitation Period, the Purchaser and the Designated Purchasers shall not, without the Sellers’ advance written consent, either directly or indirectly solicit for employment (i) any of the employees of the Sellers who are not Employees, unless the employment of such employee is involuntarily terminated by the Sellers prior to such action by the Purchaser or the Designated Purchasers, (ii) any Employees who have rejected their Offer or objected to their transfer of employment to the Purchaser or Designated Purchasers pursuant to this Agreement, or (iii) any Employees to whom the Purchaser or any Designated Purchaser have not made an Offer; provided, however, that nothing in this Section 7.4(f) shall prevent the Purchaser or the Designated Purchasers from (A) conducting generalized employment searches, including placing bona fide public advertisements, that are not specifically targeted at such employees or former employees of the Sellers, or (B) hiring such employees or former employees identified through such generalized employment searches; provided, further, that, with respect to any Employee described in clauses (ii) and (iii) above who becomes employed with the Purchaser or a Designated Purchaser (other than by operation of Law) during the ninety-day period following the Closing Date, the Purchaser and the Designated Purchasers shall be required to reimburse the Sellers, if applicable, for any pay in lieu of notice (including WARN Act notice) and/or severance payments to the extent paid by the Sellers to such Employee.

          (g) Neither the Sellers nor any of their Affiliates shall enforce against any Transferred Employee any, non-compete, non-solicit or similar contractual obligations, or otherwise assert, with respect to any such Transferred Employee or the Purchaser or any of its Affiliates, claims that would otherwise prohibit or restrict such Transferred Employee’s employment with the Purchaser or any of its Affiliates in the Business.

     SECTION 7.5. Canadian Pension Plans.

         7.5.1. Non-Union Defined Benefit. As of the relevant Effective Hire Date, each Non-Union Employee who has any entitlement to defined benefits under the Nortel Networks Limited Managerial and Non-Negotiated Pension Plan (the “Nortel Plan”), whether such Non-Union Employee was accruing such benefits as of such Effective Hire Date or whether accrual had ceased prior to such date, shall cease to participate actively in such Seller Employee Plan. The Purchaser shall cause all such Non-Union Employees who become Transferred Employees to participate in a defined contribution registered pension plan (the “Canadian Non-Union DC Replacement Plan”) to be established by the relevant Designated Purchaser effective as of the day after the Closing Date. The Purchaser shall cause the Canadian Non-Union DC Replacement Plan to recognize the prior service of such Transferred Employees with the Seller

for the purposes of eligibility to participate, vesting and entitlement to benefits. The Canadian Non-Union DC Replacement Plan shall contain an employer contribution formula of at least 1% of the salary of such Transferred Employees, subject to any applicable Tax Law. The Designated Purchaser shall maintain the Canadian Non-Union DC Replacement Plan in respect of such Transferred Employees (A) for at least five (5) years after the Closing Date or their respective employment termination dates with the Designated Purchaser or (B) until the wind-up of the Nortel Plan, whichever is earlier, without any adverse amendment. For greater certainty, there shall be no transfer of assets or liabilities from the Nortel Plan to the Canadian Non-Union DC Replacement Plan or any other Purchaser Employee Plan in respect of defined benefit accruals.

            7.5.2. Non-Union Defined Contribution. As of the relevant Effective Hire Date, each Non-Union Employee who participates only in the defined contribution component of the Nortel Plan shall cease to participate actively in, and accrue benefits under, such Seller Employee Plan. The Purchaser shall cause all such Non-Union Employees to participate in the Canadian Non-Union DC Replacement Plan beginning as of the relevant Effective Hire Date. The Purchaser shall cause the Canadian Non-Union DC Replacement Plan to recognize the prior service of such Transferred Employees with the Seller for the purposes of eligibility to participate, vesting and entitlement to benefits. The Canadian Non-Union DC Replacement Plan shall contain an employer contribution formula of at least 1% of the salary of such Transferred Employees, subject to any applicable Tax Law.

            7.5.3. Union Defined Benefit. As of the relevant Effective Hire Date, each Union Employee who was accruing defined benefits under the Nortel Networks Negotiated Pension Plan shall cease to participate actively in, and accrue benefits under, such Seller Employee Plan. The Purchaser shall cause all such Union Employees who become Transferred Employees to participate in a defined benefit registered pension plan (the “Canadian DB Replacement Plan”) to be established by the relevant Designated Purchaser effective as of the day after the Closing Date and which shall contain a benefit formula which is no less favorable than the formula in the Nortel Networks Negotiated Pension Plan and which shall otherwise comply with the applicable Collective Labor Agreement. The Purchaser shall cause the Canadian DB Replacement Plan to recognize the prior service of such Transferred Employees with the Seller for the purposes of eligibility to participate, vesting and entitlement to benefits, but not for the purpose of benefit accrual. For greater certainty, there shall be no transfer of assets or liabilities from the Nortel Networks Negotiated Pension Plan to the Canadian DB Replacement Plan or any other Purchaser Employee Plan.

            7.5.4. Union Defined Contribution. As of the relevant Effective Hire Date, each Union Employee who participates in the defined contribution component of the Nortel Networks Negotiated Pension Plan shall cease to participate actively in, and accrue benefits under, such plan. The Purchaser shall cause all such Union Employees who become Transferred Employees to participate in a defined contribution registered pension plan (the “Canadian Union DC Replacement Plan”) to be established by the Purchaser effective as of the day after the Closing Date and which shall comply with the applicable Collective Labor Agreement. The Purchaser shall cause the Canadian Union DC Replacement Plan to recognize the prior service of such Transferred Employees with the Seller for the purposes of eligibility to participate, vesting and entitlement to benefits.

            SECTION 7.6. Sole Benefit of Sellers and Purchaser. The terms and provisions of this Article VII are for the sole benefit of the Parties. Nothing contained herein, express or implied (i) shall be construed to establish, amend, or modify any Seller Employee Plan, any Purchaser Employee Plan, or any other benefit plan, program, agreement or arrangement, (ii) shall alter or limit the ability of the Purchaser, the Sellers, or any of their respective Affiliates to amend, modify or terminate any Seller Employee Plan, any Purchaser Employee Plan (other than as provided in Section 7.5), or any other benefit or employment plan, program, agreement or arrangement after the Closing Date, (iii) is intended to confer or shall confer upon any current or former employee any right to employment or continued employment, or constitute or create an employment agreement with any Transferred Employee, or (iv) is intended to confer or shall confer upon any individual or any legal representative of any individual (including employees, retirees, or dependents or beneficiaries of employees or retirees and including collective bargaining agents or representatives) any right as a third-party beneficiary of this Agreement.

ARTICLE VIII
REGISTRATION AND SALE OF CONVERTIBLE NOTES

          SECTION 8.1. Shelf Registration.

          (a) In the event that, at issuance, the Convertible Notes and all Shares issuable upon conversion thereof (the “Registrable Securities”) are not freely transferable by the Distribution Agent without restrictions under the Securities Act, provided that the Sellers have complied with their obligations to deliver the information, including the Audited Financial Statements and Unaudited September 30, 2008 Financial Statements, as may be required by and within the time periods specified in Section 5.26, on or prior to the later of (x) the 30^th calendar day following the Closing and (y) sixty (60) days following the receipt of such information and financial statements from the Sellers as are required by the rules and regulations promulgated under the Securities Act in connection with the filing and effectiveness of the Shelf Registration Statement referred to below, the Purchaser shall prepare and file an automatic shelf registration statement on Form S-3 (or other applicable form) (together with any amendments or supplements thereto, the “Initial Shelf Registration Statement”), to permit the immediate resale of the Registrable Securities under the Securities Act by the Sellers and shall use its commercially reasonable efforts to cause the Initial Shelf Registration Statement or any shelf registration statement filed to replace the Initial Registration Statement to permit the resale of the Registrable Securities should the Initial Shelf Registration Statement no longer be effective (together with any amendments or supplements thereto, and collectively with the Initial Shelf Registration Statement, the “Shelf Registration Statement”) to remain continuously effective until the later of (i) one year after the Closing and (ii) when the sale by the Sellers of the Registrable Securities are no longer subject to the volume limitations set forth in Rule 144(e) under the Securities Act (such period, the “Effective Period”); provided that the Purchaser may by written notice to the Distribution Agent immediately suspend the use of the Shelf Registration Statement for:

     (i) any period starting on the date on which additional financial statements for the Business with respect to any interim period that begins after the date of the latest period covered by the Audited Financial Statements but ends

prior to the Closing Date and that are not then included in the Shelf Registration Statement and any financial statements for the corresponding period of the preceding fiscal year that, in each case, are required by the rules and regulations promulgated under the Securities Act to be included or incorporated by reference in the Shelf Registration Statement (the “Additional Statements”) and ending three (3) Business Days after the date on which the Sellers have provided such Additional Statements to the Purchaser. The Purchaser shall provide the Main Sellers and their representatives reasonable access to the records and employees of the Business to the extent relevant for the preparation and delivery of any Additional Statements and shall cause the employees of the Business to provide the Main Sellers with such cooperation as they shall reasonably request in connection with their preparation and delivery of any Additional Statements;

     (ii) any period starting on the date that the Purchaser’s board of directors (or a committee thereof) concludes that any previously issued financial statements included in, or incorporated by reference into, such Shelf Registration Statement should no longer be relied upon because of an error in such financial statements as addressed in Accounting Principles Board Opinion No. 20, as may be modified, supplemented or succeeded, and ending on the date on which the Purchaser takes corrective action necessary to permit sales under the Shelf Registration Statement to resume; and

     (iii) a period not to exceed twenty (20) consecutive days in any one instance and for a period not to exceed forty-five (45) days in any six (6) month period, without regard to any period of suspension pursuant to the immediately preceding clauses, at any time that the Purchaser becomes engaged in a material business activity or negotiation or any other event has occurred or is anticipated, which activity, negotiation or event is not disclosed in that prospectus and that the Purchaser’s board of directors (or a committee thereof) reasonably believes after consultation with counsel should be disclosed therein under applicable Law and determines in good faith that such disclosure would be premature or would adversely affect the Purchaser or its business or prospects; provided, however, that the Purchaser may not suspend the use of the Shelf Registration Statement pursuant to this clause (iii) during the sixty (60) consecutive Trading Day period commencing on the effective date of the Shelf Registration Statement.

     The Purchaser will use its reasonable best efforts to ensure that the use of the Shelf Registration Statement may be resumed immediately following any such period of suspension (including by taking such corrective actions as referred to in clause (ii) above).

          (b) At its expense, the Purchaser will use reasonable best efforts during the Effective Period to:

     (i) prepare and file with the SEC such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of the Registrable Securities covered by the Shelf Registration Statement;

     (ii) furnish such number of prospectuses and any amendments or supplements thereto, as the Distribution Agent, the Sellers or the EMEA Sellers from time to time may reasonably request;

     (iii) promptly amend the Shelf Registration Statement onto a form the Purchaser is then eligible to use or file a new registration statement on such form and to keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement if the Purchaser ceases to be a WKSI;

     (iv) make and keep adequate current public information with respect to the Purchaser available in accordance with Rule 144 under the Securities Act; and

     (v) file with the SEC in a timely manner all reports and other documents required of the Purchaser under the Securities Act and the Exchange Act.

          SECTION 8.2. Offerings.

          (a) At any time that a Shelf Registration Statement covering Registrable Securities pursuant to Section 8.1 is effective, if the Sellers and the EMEA Sellers deliver a notice to the Purchaser (a “Shelf Take-Down Notice”) stating that the Sellers and the EMEA Sellers intend to effect an offering of all or part of the Registrable Securities included by the Sellers and the EMEA Sellers on the Shelf Registration Statement (a “Shelf Offering”) and stating the number or dollar amount of the Registrable Securities to be included in such Shelf Offering, then the Purchaser shall amend or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf Offering as contemplated by the Shelf Take-Down Notice.

          (b) The Sellers and the EMEA Sellers may withdraw their Registrable Securities from a Shelf Offering at any time by providing the Purchaser with written notice. Upon receipt of such written notice, the Purchaser shall cease all efforts to secure registration.

          (c) In connection with an underwritten public Shelf Offering, the Sellers and the EMEA Sellers shall have the right to select an internationally recognized investment banking firm reasonably acceptable to the Purchaser as the lead or managing underwriter.

          (d) In connection with any underwritten public offering made pursuant to a Registration Statement, the Purchaser will not effect any public sale or distribution of any shares of its Common Stock (or securities convertible into or exchangeable or exercisable for its Common Stock (“Convertible Securities”)) for its own account (other than (x) a registration statement (i) on Form S-4, Form S-8 or any successor forms thereto or (ii) filed solely in connection with an exchange offer or any employee benefit or dividend reinvestment plan or (y) pursuant to such underwritten offering), during the period commencing on, and continuing for not more than 60 days (or such shorter period as the managing underwriter(s) may permit) after the effective date of such Registration Statement

pursuant to which such underwritten offering shall be made or, in the case of a Shelf Registration Statement, the period commencing on, and continuing for not more than 60 days (or such shorter period as the managing underwriter(s) may permit) after the Purchaser’s notice of a distribution in connection with such offering, or, in either case, on such earlier date as the Sellers and the EMEA Sellers give notice to the Purchaser that they decline to proceed with any such offering, except (i) for the issuance of shares of Common Stock upon the conversion, exercise or exchange, by the holders thereof, of Convertible Securities pursuant to the terms of such Convertible Securities, (ii) pursuant to the terms of any other agreement to issue shares of Common Stock or any Convertible Securities in effect on the date of the notice of a proposed Transfer, including any such agreement in connection with any previously disclosed acquisition, merger, consolidation or other business combination, and (iii) in connection with Transfers to dividend reinvestment plans or to employee benefit plans in order to enable any such employee benefit plan to fulfill its funding obligations in the ordinary course, unless the managing underwriter(s) agree otherwise. Notwithstanding the foregoing, the provisions of this Section 8.2(d) shall be subject to the provisions of Section 8.1(a), and if the Purchaser exercises its rights of postponement pursuant to Section 8.1(a) with respect to any proposed underwritten public offering, the provisions of this Section 8.2(d) shall not apply unless and until such time as the Purchaser notifies the Sellers and the EMEA Sellers of the termination of such postponement and the Sellers and the EMEA Sellers notify the Purchaser of their intention to continue with such proposed offering.

          SECTION 8.3. Piggyback Registration.

          (a) If at any time after the issuance of Convertible Notes, the Purchaser proposes or is required to file a registration statement under the Securities Act with respect to an offering of shares of Common Stock or Convertible Securities for its own account (other than (i) a registration statement filed pursuant to Section 8.1(a), (ii) a registration statement on Form S-4 or S-8 or any successors thereto, or (iii) a registration statement solely relating to an offering and sale to employees or directors of the Purchaser pursuant to any employee stock plan or other employee benefit plan arrangement), then the Purchaser shall give prompt written notice of such proposed filing at least ten (10) days before the anticipated filing date (the “Piggyback Notice”) to the Distribution Agent. The Piggyback Notice shall offer the Sellers and the EMEA Sellers the opportunity to include in such registration statement the number of Shares (with respect to an offering of shares of Common Stock) or the aggregate principal amount of Convertible Notes (with respect to an offering of Convertible Securities) as they may request (a “Piggyback Registration”). Subject to Section 8.3(b), the Purchaser shall include in each such Piggyback Registration all Shares or Convertible Notes (as applicable) with respect to which the Purchaser has received a written request for inclusion therein within five (5) days after notice has been given to the Distribution Agent. The Sellers and the EMEA Sellers shall be permitted to withdraw all or part of any Registrable Securities from a Piggyback Registration at any time up to the pricing date.

          (b) If any of the shares of Common Stock or Convertible Securities to be registered pursuant to the registration giving rise to the Sellers’ and the EMEA Sellers’ rights under this Section 8.3 are to be sold in an underwritten public offering, the Sellers and the EMEA Sellers shall be permitted to include all Registrable Securities requested to be

included in such registration in such offering on the same terms and conditions as any other shares of Common Stock or Convertible Securities of the Purchaser included therein; provided, that if such offering is subject to an Offering Limitation, then there shall be included in such offering: (i) first, the number of shares of Common Stock or Convertible Securities the Purchaser proposes to sell, and (ii) second, the number of Registrable Securities requested to be included in such registration by the Sellers and the EMEA Sellers that in the opinion of the underwriter selected by the Purchaser can be sold without adversely affecting the price, timing, distribution or marketability of such offering.

          (c) The Purchaser may select the lead underwriter and co-manager or co-managers to administer any offering of Registrable Securities pursuant to a Piggyback Registration; provided, however, that if the Sellers and the EMEA Sellers’ Registrable Securities that are expected to be included in any such offering constitute, in the Purchaser’s reasonable judgment, at least 25% of the shares of Common Stock or aggregate principal amount of Convertible Securities expected to be transferred in such offering, the Sellers and the EMEA Sellers shall have the right to appoint one co-manager (reasonably acceptable to the Purchaser) for such offering, who shall participate in such offering on the same terms as the co-managers appointed by the Purchaser.

          (d) In the event that the Purchaser gives the Distribution Agent notice of its intention to effect an offering pursuant to a Piggyback Registration and subsequently declines to proceed with such offering, the Sellers and the EMEA Sellers shall have no rights in connection with such offering. The Sellers and the EMEA Sellers shall participate in any offering of Registrable Securities pursuant to a Piggyback Registration in accordance with the same plan of distribution for such Piggyback Registration as the Purchaser.

          (e) No registration of Shares effected pursuant to a request under this Section 8.3 shall relieve the Purchaser of its obligations under Section 8.1 or 8.2.

          SECTION 8.4. No Inconsistent Agreements. Nothing herein shall restrict the authority of the Purchaser to grant to any Person the rights to obtain registration under the Securities Act of any equity securities of the Purchaser, or any securities convertible into or exchangeable or exercisable for such securities; provided, however, that the Purchaser shall not grant any such rights with respect to the Common Stock or Convertible Securities that conflicts with the rights of the Sellers or the EMEA Sellers under this Agreement; provided that in the event that Purchaser issues any Common Stock or Convertible Securities in connection with any acquisition of any other Person, the Purchaser may grant such other Person registration rights (including the rights in Section 8.3(b) which shall be deemed modified hereby) that are pari passu with the Sellers.

          SECTION 8.5. Registration Procedures.

          (a) The Purchaser is required to effect the registration of any Registrable Securities under the Securities Act as provided in Article VIII in a manner to permit the sale of such Registrable Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Purchaser shall cooperate in the sale of the securities and shall, as expeditiously as possible:

     (i) Before filing a Registration Statement or any prospectus (including any issuer free writing prospectus related thereto) or any amendments or supplements thereto, furnish or otherwise make available to the Sellers, the EMEA Sellers, their counsel and the managing underwriter(s), if any, copies of all such documents proposed to be filed, which documents will be subject to the reasonable review and comment of such counsel (provided that any comments made on behalf of the Sellers, the EMEA Sellers or the managing underwriter(s), if any, are provided to the Purchaser promptly upon receipt of the documents but in no event later than three (3) Business Days after receipt of such documents by the Sellers and the EMEA Sellers), and the managing underwriters, if any, and such other documents reasonably requested by such counsel, including any comment letter from the SEC, and, if requested by such counsel, provide such counsel reasonable opportunity to participate in the preparation of such Registration Statement and each prospectus included therein (including any issuer free writing prospectus related thereto) and such other opportunities to conduct a reasonable investigation within the meaning of the Securities Act, including reasonable access to the Purchaser’s books and records, officers, accountants and other advisors. The Purchaser shall not file any such Registration Statement or prospectus (including any issuer free writing prospectus related thereto) or any amendments or supplements thereto with respect to any registration pursuant to which the Sellers, the EMEA Sellers, their counsel, or the managing underwriter(s), if any, shall reasonably object, in writing, on a timely basis, unless, in the opinion of the Purchaser, such filing is necessary to comply with applicable Law.

     (ii) Notify the Sellers, the EMEA Sellers and the managing underwriter(s), if any, promptly (A) when a prospectus or any prospectus supplement, issuer free writing prospectus or post-effective amendment has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective, (B) of any request by the SEC or any other Government Entity for amendments or supplements to the Registration Statement or related prospectus or issuer free writing prospectus or for additional information, (C) of the issuance by the SEC of any stop order suspending the effectiveness of any registration statement of the Purchaser or the initiation of any proceedings for that purpose, (D) if at any time the representations and warranties of the Purchaser contained in any agreement related to the Registrable Securities (including this Agreement and any underwriting agreement contemplated hereunder) cease to be true and correct, (E) of the receipt by the Purchaser of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable

Securities for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, and (F) of the happening of any event that makes any statement made in such Registration Statement or related prospectus or issuer free writing prospectus untrue in any material respect or that requires the making of any changes in such Registration Statement, prospectus, documents or issuer free writing prospectus so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of any prospectus or issuer free writing prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

     (iii) Use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction at the reasonably earliest practical date.

     (iv) If requested by the managing underwriter(s), if any, or the Sellers and the EMEA Sellers, promptly include in a prospectus supplement, post-effective amendment or issuer free writing prospectus such information as the managing underwriter(s), if any, or the Sellers and the EMEA Sellers may reasonably request in order to permit the intended method of distribution of such securities and make all required filings of such prospectus supplement, such post- effective amendment or issuer free writing prospectus as soon as practicable after the Purchaser has received such request.

     (v) Furnish or make available to the Sellers, the EMEA Sellers and each managing underwriter, if any, without charge, such number of conformed copies of the Registration Statement and each post-effective amendment thereto, including financial statements (but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits, unless requested in writing by the Sellers, the EMEA Sellers, counsel or managing underwriter(s)), and such other documents, as the Sellers, the EMEA Sellers or such managing underwriter(s) may reasonably request, and upon request a copy of any and all transmittal letters or other correspondence to or received from the SEC or any other Government Entity relating to such offering.

     (vi) Deliver to the Sellers, the EMEA Sellers and the managing underwriter(s), if any, without charge, as many copies of the prospectus or prospectuses (including each form of prospectus and any issuer free writing prospectus related to any such prospectuses) and each amendment or supplement thereto as such Persons may reasonably request in connection with the distribution of the Registrable Securities; and the Purchaser, subject to Section 8.5(b), hereby consents to the use of such prospectus and each amendment or supplement thereto by each of the Sellers, the EMEA Sellers and the managing underwriter(s), if any, in connection with the offering and sale of the Registrable

Securities covered by such prospectus and any such amendment or supplement thereto.

     (vii) Prior to any public offering of Registrable Securities, use its commercially reasonable efforts to register or qualify or cooperate with the Sellers, the EMEA Sellers, the managing underwriter(s), if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or “blue sky” laws of such jurisdictions within the United States as any Seller, EMEA Seller or managing underwriter(s) reasonably requests in writing and to keep each such registration or qualification (or exemption therefrom) effective during the Effective Period and to take any other action that may be necessary or advisable to enable the Sellers and the EMEA Sellers to consummate the disposition of such Registrable Securities in such jurisdiction; provided, however, that the Purchaser will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject.

     (viii) Cooperate with the Sellers, the EMEA Sellers and the managing underwriter(s), if any, to facilitate the timely preparation and delivery of certificates (not bearing any legends) representing Registrable Securities to be sold after receiving a written representation from the Sellers and the EMEA Sellers that the Registrable Securities represented by the certificates so delivered by the Sellers and the EMEA Sellers will be transferred in accordance with the Registration Statement, and enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriter(s), if any, or the Sellers and the EMEA Sellers may request at least two (2) Business Days prior to any sale of Registrable Securities.

     (ix) Upon the occurrence of any event contemplated by Section 8.5(a)(ii)(B) through Section 8.5(a)(ii)(F), at the request of the Sellers and the EMEA Sellers, prepare and file with the SEC a supplement or post-effective amendment to such Registration Statement, prospectus or issuer free writing prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances in which they are made, not misleading.

     (x) Prior to the effective date of the Registration Statement, provide a CUSIP number for the Registrable Securities (if the Registrable Securities do not already have a CUSIP number) and make the Registrable Securities eligible for settlement and transfer through the facilities of The Depository Trust Company (“DTC”).

     (xi) So long as the Common Stock is listed on any United States securities exchange, quotation system or market, use its commercially reasonable

The above shall be done at each closing under such underwriting or similar agreement, or as and to the extent required thereunder.

     (xiv) Not later than the effective date of the Shelf Registration Statement, cause the Indenture to be qualified under the Trust Indenture Act of 1939 (as amended, the “TIA”); and, in connection therewith, cooperate with the Trustee to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and execute, and use its reasonable best efforts to cause the Trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner.

     (xv) If requested by the lead manager for any underwritten offering of any Convertible Notes, the Purchaser shall at its own expense, use its best efforts to (a) if the Convertible Notes have been rated prior to such underwritten offering, confirm such ratings will apply to the Convertible Notes to be offered in such underwritten offering, or (b) if the Convertible Notes were not previously rated, cause the Convertible Notes to be offered in such offering to be rated by such rating agencies, as requested by the managing underwriters of such underwritten offering.

Nothing herein shall be construed to require the Purchaser or any of its Affiliates to make any public disclosure of information at any time. In the event the Purchaser has notified the Sellers and the EMEA Sellers of any occurrence of any event contemplated by Section 8.5(a)(ii)(B) through Section 8.5(a)(ii)(F) then the Sellers and the EMEA Sellers shall not deliver such prospectus or issuer free writing prospectus to any purchaser and will forthwith discontinue disposition of any Registrable Securities covered by such Registration Statement, prospectus or issuer free writing prospectus unless and until a supplement or post-effective amendment to such prospectus or issuer free writing prospectus has been prepared and filed as set forth in Section 8.5(a)(ix) or until the Purchaser advises the Sellers and the EMEA Sellers in writing that the use of such prospectus or issuer free writing prospectus may be resumed.

either by conference call or, if in person, at a location acceptable to the Purchaser acting reasonably), and for such assistance as is reasonably requested by the Sellers, the EMEA Sellers and their counsel in the selling efforts relating to any such offering; provided, however, that management need only be made available for one offering in any 6-month period.

          SECTION 8.7. Registration Expenses and Legal Counsel. The Purchaser shall pay all reasonable fees and expenses incident to the performance of or compliance with its obligations under this Article VIII, including (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with all applicable securities exchanges and/or the Financial Industry Regulatory Authority, Inc., and (B) of compliance with securities or “blue sky” laws including any fees and disbursements of counsel for the underwriter(s) in connection with “blue sky” qualifications of the Registrable Securities pursuant to Section 8.5(a)(viii), (ii) printing expenses (including expenses of printing certificates for Registrable Securities in a form eligible for deposit with DTC and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter(s), if any, or by the Sellers and the EMEA Sellers), (iii) messenger, telephone and delivery expenses of the Purchaser, (iv) fees and disbursements of counsel for the Purchaser, (v) expenses of the Purchaser incurred in connection with any “road show” and (vi) fees and disbursements of all independent registered public accounting firms (including, without limitation, the expenses of any special audit and “cold comfort” letters required by or incident to this Agreement) and any other persons, including special experts, retained by the Purchaser other than the fees and expenses of KPMG or any other accounting firm in connection with the preparation or audit of the Audited Financial Statements or the Additional Statements or any comfort given thereon (“Nortel Accounting Expenses”). For the avoidance of doubt, the Purchaser shall not be required to pay underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of Registrable Securities pursuant to any Registration Statement, the fees and expenses of counsel for the underwriter selected by the Sellers and the EMEA Sellers, the Nortel Accounting Expenses or any other expenses of the Sellers and the EMEA Sellers. In addition, the Purchaser shall bear all of its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the Common Stock issuable upon conversion of Convertible Notes on any securities exchange or inter-dealer quotation system and the fees and expenses of any Person, including special experts, retained by the Purchaser.

          SECTION 8.8. Indemnification.

          (a) As a condition to any Seller’s or EMEA Seller’s inclusion in a Registration Statement as a selling shareholder, such Seller or EMEA Seller shall, severally and not jointly, indemnify the Purchaser, each person, if any, who controls the Purchaser within the meaning of the Securities Act or the Exchange Act, and each officer or director of the Purchaser, against all losses, claims, damages or liabilities (including any loss, damage, claim or liability under the Securities Act, the Exchange Act, state securities laws or otherwise) arising out of or based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading and each agrees, severally and not jointly, to reimburse the Purchaser and each such officer, director

and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending such loss, claim, damage, liability or action, provided, however, that any Seller or EMEA Seller shall only be liable hereunder in any such case if and only to the extent that any such loss, claim, damage, liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus or final prospectus, or any such amendment or supplement, in reliance upon and in conformity with information pertaining to such Seller or EMEA Seller, as such, as furnished in writing to the Purchaser by or on behalf of the Sellers or the EMEA Sellers, respectively, specifically for use in the preparation thereof, provided, further, however, that the liability of each of the Sellers and the EMEA Sellers hereunder shall not in any event exceed the net proceeds received by such Seller or EMEA Seller from the sale of Registrable Securities covered by such Registration Statement. The Purchaser will indemnify and hold harmless each of the Sellers and the EMEA Sellers selling Registrable Securities registered on such Registration Statement and each other person, if any, who controls any of them within the meaning of the Securities Act or Exchange Act, and each officer, director or agent of any of them, against any losses, claims, damages or liabilities (including any loss, damage, claim or liability under the Securities Act, the Exchange Act or state securities Laws) or otherwise to the extent such losses, claims, damages or liabilities arise out of or based upon any untrue statement or alleged untrue statement of any material fact contained in such Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading and the Purchaser will reimburse each such Seller and EMEA Seller and each such officer, director, agent and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, provided, however, that the Purchaser will not be liable hereunder in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus or final prospectus or any such amendment or supplement, in reliance upon and in conformity with information pertaining to any of the Sellers or the EMEA Sellers, as such, as furnished in writing to the Purchaser by or on behalf of any of them specifically for use in the preparation thereof. The Purchaser shall bear all costs and expenses associated with the registration of the Registrable Securities as specified in Article VIII and the preparation and filing of such Registration Statement, the Purchaser’s outside counsel, NASDAQ and “blue sky” registration and filing fees and transfer agents’ and registrars’ fees and legal fees and disbursements of counsel to the Sellers or the EMEA Sellers.

          (b) If the indemnification provided for in Section 8.8(a) is unavailable to a Person intended to be indemnified under Section 8.8(a) (an “Indemnitee”) in respect of any losses, damages, claims or liabilities referred to herein, then, as a condition to any Seller’s or EMEA Seller’s inclusion in such Registration Statement as a selling shareholder, the Person who was to provide the indemnity under Section 8.8(a) (an “Indemnitor”), in lieu of indemnifying such Indemnitee hereunder, shall contribute to the amount paid or payable by such Indemnitee as a result of such losses, damages, claims or liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnitor and the Indemnitee

and the Persons acting on behalf of or controlling the Indemnitor or the Indemnitee in connection with the statements or omissions or violations which resulted in such losses, damages, claims or liabilities, as well as any other relevant equitable considerations. If the indemnification described in Section 8.8(a) is unavailable to an Indemnitee, the relative fault of the Indemnitor and the Indemnitee and Persons acting on behalf of or controlling the Indemnitor or the Indemnitee shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnitor or the Indemnitee or the Persons acting on behalf of or controlling the Indemnitor or the Indemnitee and their relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Indemnitor shall not be required to contribute pursuant to this Section 8.8(b) if there has been a settlement of any proceeding affected without its written consent. No claim against the assets of the Sellers or the EMEA Sellers shall be created by this Section 8.8(b), except as and to the extent permitted by applicable Law. Notwithstanding the foregoing, no Seller or EMEA Seller shall be required to make a contribution in excess of the net amount received by such Seller or EMEA Seller from the sale of the Registrable Securities in the offering giving rise to such liability.

          SECTION 8.9. Trading Limitation. The Sellers and EMEA Sellers agree that (i) none of them will transfer any Convertible Notes or the right to receive the Convertible Notes other than (w) to the Sellers, the EMEA Sellers or their respective subsidiaries, (x) distributions to the Sellers’ or the EMEA Sellers’ creditors and other stakeholders, either directly or indirectly through a liquidating trust or other similar vehicle, whether pursuant to a plan of compromise and/or arrangement, plan of reorganization, plan of liquidation, scheme of arrangement, or otherwise, (y) through a “block trade” or a broadly marketed offering effected through an internationally recognized convertible bond dealer (“Recognized Dealer”) in accordance with Section 8.1 or (z) outside the context of clause (y), with the consent of the Purchaser, to a Recognized Dealer in accordance with applicable securities laws, which consent of the Purchaser shall not be unreasonably withheld or delayed (it being understood that such consent may be withheld unless such Recognized Dealer provides Purchaser with reasonable assurances that the Convertible Notes will not ultimately be placed in an unreasonably concentrated manner); and (ii) to the extent the Convertible Notes have been converted into Common Stock, the aggregate amount of Shares sold for the account of the Sellers and EMEA Sellers collectively, whether pursuant to a Registration Statement or otherwise, shall not exceed the Daily Trading Limit.

          SECTION 8.10. Agent of Sellers. The Sellers, the EMEA Sellers or any of them may act through the Distribution Agent in connection with the exercise of any rights or the performance of any actions or obligations under this Article VIII.

          SECTION 8.11. Liquidated Damages.

            In the event that (i) the Purchaser has not filed the Shelf Registration Statement on or before the date on which such registration statement is required to be filed pursuant to Section 8.1(a), or (ii) any Shelf Registration Statement required by Section 8.1(a) hereof is filed and declared effective but shall thereafter either be withdrawn by the Purchaser in violation of its obligations in Section 8.1 (a), or shall become subject to an effective stop order issued pursuant to Section 8(d) of the Securities Act suspending the effectiveness of such registration statement without being succeeded immediately by an additional registration statement filed and declared

effective (each such event referred to in clauses (i) and (ii), a “Registration Default” and each period during which a Registration Default has occurred and is continuing, a “Registration Default Period”), then, as liquidated damages for such Registration Default, subject to the provisions of Section 11.13, liquidated damages shall accrue on the Aggregate Principal Amount at a per annum rate of 0.25% for the first 90 days of the Registration Default Period, and at a per annum rate of 0.50% thereafter for the remaining portion of the Registration Default Period.

Notwithstanding the foregoing provisions of this Section 11.4, (a) no Third Party Beneficiary shall be deemed to have waived any Third Party Provision unless such waiver is in writing, and then such waiver shall be limited to the circumstances set forth in such written waiver and (b) no Third Party Provision shall be amended, altered or qualified except by an instrument in writing signed by all the parties hereto and the Third Party Beneficiaries affected by such amendment, alteration or qualification.

          SECTION 11.5. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned (whether directly or indirectly) by any Party without the prior written consent of the other Party, which consent may be withheld in such party’s sole discretion, except for (i) direct assignment by any Seller to an Affiliate (provided that the applicable Seller remains liable jointly and severally with its assignee Affiliate for the assigned obligations), (ii) direct assignment by the Purchaser to a Designated Purchaser (provided that the Purchaser remains liable jointly and severally with its assignee Designated Purchaser for the assigned obligations), (iii) direct assignment by a U.S. Debtor to a succeeding entity following such U.S. Debtor’s emergence from Chapter 11, and (iv) direct assignment by any of the Canadian Debtors pursuant to any plan of arrangement approved by the Canadian Court, which will not require the consent of the Purchaser.

EACH PARTY (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE ANCILLARY AGREEMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.6.

          SECTION 11.8. Exhibits; Sellers Disclosure Schedule.

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

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

          SECTION 11.9. 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. Delivery of an executed counterpart of a signature page to this Agreement by telecopier or electronic mail attachment shall be effective as delivery of a manually executed counterpart of this Agreement.

          SECTION 11.10. 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 11.11. 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, any provision 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 11.12. Entire Agreement.

          (a) This Agreement, the EMEA Asset Sale Agreement, the Ancillary Agreements and the Confidentiality Agreement 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 11.13. Availability of Equitable Relief. Each Party agrees that irreparable damage would occur in the event that any of the provisions of this Agreement that it is required to perform were not performed in accordance with their specific terms or were otherwise breached. Accordingly, subject to the limitations set forth in this Section 11.13 and Section 10.2(a), each Party shall be entitled to equitable relief to prevent or remedy breaches of this Agreement prior to the Closing, and for any breach of Section 5.36, Section 8.1, Section 8.2, Section 8.3, Section 8.4, Section 8.5 and Section 8.6 following the Closing, without the proof of actual damages, including in the form of an injunction or injunctions or orders for specific performance in respect of such breaches. Each Party agrees to waive any requirement for the security or posting of any bond in connection with any such equitable remedy. Each Party further agrees that the only permitted objection that it may raise in response to any action for equitable relief is that it contests the existence of a breach or threatened breach of the provisions of this Agreement. For avoidance of doubt, under no circumstances shall the Sellers be liable for punitive damages or indirect, special, incidental, or consequential 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, including damages alleged as a result of tortious conduct.

          SECTION 11.14. Bulk Sales Laws. Each Party waives compliance by the other Party with any applicable bulk sales Law.

          SECTION 11.15. Main Sellers as Representatives of Other Sellers.

          (a) For all purposes of this Agreement:

     (i) each Other Seller listed in Section 11.15(a)(i) of the Sellers Disclosure Schedule hereby irrevocably appoints NNC as its representative;

     (ii) each Other Seller listed in Section 11.15(a)(ii) of the Sellers Disclosure Schedule hereby irrevocably appoints NNL as its representative; and

     (iii) each Other Seller listed in Section 11.15(a)(iii) of the Sellers Disclosure Schedule hereby irrevocably appoints NNI as its representative.

          (b) Pursuant to Section 11.15(a), each of NNC, 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) make 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 NNC, each Other Seller listed in Section 11.15(a)(i) of the Sellers Disclosure Schedule; (ii) with respect to NNL, each Other Seller listed in Section 11.15(a)(ii) of the Sellers Disclosure Schedule, and (iii) with respect to NNI, all the other U.S. Debtors and each Other Seller listed in Section 11.15(a)(iii) of the Sellers Disclosure Schedule.

          (d) Each Respective Affiliate shall indemnify the Main Seller that acts as representative of such Respective Affiliate pursuant to this Section for, and hold it harmless against, any loss, liability or expense, including reasonable attorneys’ fees, incurred by such Main Seller without gross negligence, bad faith or willful misconduct, for serving in the capacity of representative of such Respective Affiliate hereunder.

          SECTION 11.16. Obligations of 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).

          SECTION 11.17. 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 as promptly as practicable but in no event later than the day that is sixty (60) days after the date hereof, agreeing to be bound as a Seller under this Agreement and authorizing NNC, NNL or NNI, as applicable, to act as its representative under Section 11.15.
