(a) Within ninety (90) days after the Closing Date, the Buyer shall deliver to the Seller a statement (the “Statement”) of the Reference Date Working Capital, the Assumed Indebtedness, the Reference Date Cash Amount, the Advances and the Seller Transaction Expenses in each case prepared in accordance with the Balance Sheet Rules. The Buyer shall not amend, supplement or modify the Statement following its delivery to the Seller. The Buyer and the Seller acknowledge that no adjustments shall be made to the Base Amount or the Base Cash Amount.

(b) The Statement shall become final and binding upon the parties on the thirtieth (30th) day following the date on which the Statement was delivered to the Seller, unless the Seller delivers written notice of its disagreement with

the Statement (a “Notice of Disagreement”) to the Buyer prior to such date. Any Notice of Disagreement shall (i) specify in reasonable detail the nature of any disagreement so asserted and (ii) only include good faith disagreements based on Reference Date Working Capital, Assumed Indebtedness, the Reference Date Cash Amount, the Advances and/or Seller Transaction Expenses not being calculated in accordance with the Balance Sheet Rules. If a Notice of Disagreement is received by the Buyer prior to the thirtieth (30th) day following the date on which the Statement was delivered to the Seller, then the Statement (as revised in accordance with this sentence) shall become final and binding upon the Seller and the Buyer on the earlier of (A) the date the Seller and the Buyer resolve in writing any differences they have with respect to the matters specified in the Notice of Disagreement and (B) the date any disputed matters are finally resolved in writing by the Accounting Firm. During the fourteen (14)-day period following the delivery of a Notice of Disagreement, the Seller and the Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement. If at the end of such fourteen (14)-day period the Seller and the Buyer have not resolved in writing the matters specified in the Notice of Disagreement, the Seller and the Buyer shall submit to an independent accounting firm (the “Accounting Firm”) for arbitration, in accordance with the standards set forth in this Section 2.3, only matters that remain in dispute. The Accounting Firm shall be Grant Thornton LLP or, if such firm is unable or unwilling to act, such other internationally recognized independent public accounting firm or valuation firm as shall be agreed upon by the Seller and the Buyer in writing. The Seller and the Buyer shall use reasonable efforts to cause the Accounting Firm to render a written decision resolving the matters submitted to the Accounting Firm within thirty (30) days of the receipt of such submission. The scope of the disputes to be resolved by the Accounting Firm shall be limited to fixing mathematical errors and determining whether the items in dispute were determined in accordance with the Balance Sheet Rules and the Accounting Firm is not to make any other determination, including any determination as to whether the Base Amount, Working Capital Estimate, the Estimated Assumed Indebtedness Amount, the Estimated Cash Amount, Estimated Advances or the Estimated Seller Transaction Expenses are correct. The Accounting Firm’s decision shall be based solely on written submissions by the Seller and the Buyer and their respective Representatives and not by independent review and shall be final and binding on all of the parties hereto. The Accounting Firm may not assign a value greater than the greatest value for such item claimed by either party or less than the lowest value for such item claimed by either party. Judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over the party against which such determination is to be enforced. The fees and expenses of the Accounting Firm incurred pursuant to this Section 2.3 shall be borne pro rata as between the Seller, on the one hand, and the Buyer, on the other hand, in proportion to the final allocation made by such Accounting Firm of the disputed items weighted in relation to the claims made by the Seller and the Buyer, such that the prevailing party pays the lesser proportion of such fees, costs and expenses.

(c) For the purposes of this Agreement, “Final Working Capital” means the Reference Date Working Capital, “Final Seller Transaction Expenses” means Seller Transaction Expenses, “Final Cash Amount” means the Reference Date Cash Amount, “Final Assumed Indebtedness” means the Assumed

Indebtedness and “Final Advances” means the Advances, in each case as finally agreed or determined in accordance with Section 2.3(b). The Estimated Purchase Price shall be recalculated as follows: (i) increased by the sum of (1) the amount, if any, that the Final Working Capital exceeds the Working Capital Estimate, (2) the amount, if any, that the Estimated Assumed Indebtedness Amount exceeds the Final Assumed Indebtedness, (3) the amount, if any, that Final Cash Amount exceeds the Estimated Cash Amount, (4) the amount, if any, that the Estimated Seller Transaction Expenses exceeds the Final Seller Transaction Expenses; and/or (5) the amount, if any, that the Final Advances exceeds the Estimated Advances; and (ii) decreased by the sum of (1) the amount, if any, that the Working Capital Estimate exceeds the Final Working Capital, (2) the amount, if any, that the Final Assumed Indebtedness exceeds the Estimated Assumed Indebtedness Amount, (3) the amount, if any, that the Estimated Cash Amount exceeds the Final Cash Amount, (4) the amount, if any, that the Final Seller Transaction Expenses exceeds the Estimated Seller Transaction Expenses and/or (5) the amount, if any, that the Estimated Advances exceeds the Final Advances (such recalculated amount, the “Final Purchase Price”). If the Final Purchase Price is greater than the Estimated Purchase Price, the Buyer shall, within five (5) Business Days after the Final Working Capital, the Final Cash Amount, the Final Seller Transaction Expenses, the Final Advances and the Final Assumed Indebtedness have been determined, make payment by wire transfer of immediately available funds to the Seller in the amount of any such excess. If the Final Purchase Price is less than the Estimated Purchase Price, the Seller shall, within five (5) Business Days after the Final Working Capital, the Final Cash Amount, the Final Seller Transaction Expenses, the Final Advances and the Final Assumed Indebtedness have been determined, make payment by wire transfer of immediately available funds to the Buyer in the amount of any such deficit. If the Final Purchase Price is equal to the Estimated Purchase Price, neither the Seller nor the Buyer shall be required to make any payment to the other party under this Section 2.3. Upon payment of the amounts provided in this Section 2.3(c), none of the parties hereto may make or assert any claim under this Section 2.3.

(d) No actions taken by the Buyer on its own behalf or on behalf of the Company or the Company Subsidiaries, on or following the Closing Date shall be given effect for purposes of determining the Reference Date Working Capital, Reference Date Cash Amount, Seller Transaction Expenses, the Advances or Assumed Indebtedness. During the period of time from and after the Closing Date through the final determination and payment of Reference Date Working Capital, Reference Date Cash Amount, Seller Transaction Expenses, the Advances and Assumed Indebtedness in accordance with this Section 2.3, the Buyer shall cause the Company and the Company Subsidiaries to afford (subject to execution of appropriate confidentiality agreements), to the Seller and any accountants, counsel or financial advisers retained by the Seller or its Affiliates in connection with the review of Reference Date Working Capital, Reference Date Cash Amount, Seller Transaction Expenses, the Advances and Assumed Indebtedness in accordance with this Section 2.3, copies of or reasonable access during normal business hours upon reasonable advance notice to all the properties, books, contracts, personnel, Representatives (including the Company’s accountants) and records of the Company, the Company Subsidiaries and such Representatives (including the work papers of the Company’s accountants to the extent permitted by the Company’s

accountants) necessary to the review of the Statement and the Buyer’s determination of Reference Date Working Capital, Reference Date Cash Amount, Seller Transaction Expenses, the Advances and Assumed Indebtedness in accordance with this Section 2.3.

Section 2.4 Withholding. Each of the Buyer, Investments, the Company and any Company Subsidiary shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement such amounts as the Buyer, the Company or such Company Subsidiary is required to withhold from such consideration under the Code or any provision of other applicable Tax law. To the extent that amounts are so deducted and withheld and properly paid over to the applicable Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been delivered and paid to the Person in respect of which such deduction and withholding was made. To the extent that the Buyer becomes aware of any applicable withholding Taxes, the Buyer (i) shall use commercially reasonable efforts to provide prompt written notice to the Seller of the amount of such Tax and (ii) shall use commercially reasonable efforts to consult with the Seller in good faith as to the nature of the Tax and the basis upon which such withholding is required. Each of the Buyer and the Seller agrees to use their commercially reasonable efforts to obtain exemptions from, or reductions of, any Taxes required to be withheld from payments under this Agreement.

Section 6.9 Financing. The Buyer affirms that it is not a condition to the Closing or to any of its other obligations under this Agreement that the Buyer obtain financing for or related to any of the Transactions. The Buyer has delivered to the Seller true, correct and complete copies of (a) the executed debt commitment letter, dated as of the date hereof, (together with all exhibits, annexes, schedules and attachments thereto, the “Debt Commitment Letter” and together with the fee letter related thereto, the “Debt Commitment Papers”) from the Debt Financing Sources specified therein and the fee letter related thereto, which may be redacted solely with respect to fees, “flex” and economic terms, pursuant to which, and subject to the terms and conditions thereof, such Debt Financing Sources have committed to lend the amounts set forth therein to the Buyer for the purpose of funding the Transactions (the “Debt Financing”), and (b) the executed equity commitment letter, dated as of the date hereof (the “Equity Commitment Letter” and, together with the Debt Commitment Papers, the “Financing Commitments”) from certain funds affiliated with Siris Capital Group, LLC pursuant to which, and subject to the terms and conditions thereof, such funds have committed to invest the amounts set forth therein (the “Equity Financing” and, together with the Debt Financing,

the “Financing”). None of the Financing Commitments has been amended or modified prior to the date hereof, no such amendment or modification is contemplated as of the date hereof (except with respect to any “market flex” terms contained in the Debt Commitment Papers provided as of the date hereof), and the respective commitments contained in the Financing Commitments have not been withdrawn or rescinded in any respect as of the date hereof (and no such withdrawal or rescission is contemplated as of the date hereof). As of the date hereof, there are no side letters or other contracts or arrangements that could affect the amount, availability or conditions of the Financing Commitments other than as expressly set forth in the Financing Commitments furnished pursuant to this Section 6.9.

All commitments and other fees required to be paid under the Financing Commitments prior to the date hereof have been paid in full. No event has occurred that, with or without notice, lapse of time or both, would constitute a default or breach on the part of the Buyer under any term or condition of the Financing Commitments. Assuming the satisfaction of the conditions set forth in Article 8, to the Knowledge of the Buyer, there exists no fact or occurrence existing on the date hereof that, with or without notice, lapse of time or both, could reasonably be expected to (i) make any of the assumptions or any of the statements set forth in the Financing Commitments inaccurate, (ii) result in any of the terms or conditions in the Financing Commitments not being satisfied, (iii) cause the Financing Commitments to be ineffective or (iv) otherwise result in the Financing Commitments not being available on a timely basis in order to consummate the Transactions. Assuming the satisfaction of the conditions set forth in Article 8, the net proceeds from the Financing Commitments along with any additional equity financing provided by the Buyer will be sufficient to consummate the Transactions, including the payment by the Buyer of all payment obligations hereunder due and owing on the Closing Date. The Buyer has not incurred any obligation, commitment, restriction or liability of any kind, in each case, which would reasonably be expected to impair or adversely affect the availability of such proceeds for such uses.

Company Subsidiaries (1) will be solvent and (2) will be able to pay its debts as such debts become due.

Section 6.11 Litigation. There is no Proceeding pending or, to the Knowledge of the Buyer, threatened against the Buyer or any material portion of its properties or assets with respect to which there is a substantial possibility of a determination which questions the validity or legality of this Agreement or the transactions contemplated hereby or which seeks to prevent the transactions contemplated hereby or otherwise would reasonably be expected, individually or in the aggregate, to materially impair the Buyer’s ability to effect the transactions contemplated hereby.

Section 6.12 Buyer’s Reliance.

(a) The Buyer agrees that all rights to indemnification and exculpation from liability for acts or omissions occurring on or prior to the Closing Date now existing in favor of the current or former directors, officers, employees, fiduciaries or agents of the Company and the Company Subsidiaries (each, a “Company Indemnified Party,” and collectively, the “Company Indemnified Parties”), as provided in the respective articles of incorporation, by-laws (or comparable organizational documents), or in indemnification agreements, shall survive the Closing Date and shall continue in full force and effect in accordance with their respective terms for a period of not less than six (6) years after the Closing Date, which provisions shall not be amended, repealed or otherwise modified during such period in any manner that would affect adversely the rights thereunder of the Company Indemnified Parties, unless such modification shall be required by Law.

(b) The covenants contained in this Section 7.6 are intended to be for the benefit of, and shall be enforceable by, each of the Company Indemnified Parties and their respective heirs and legal representatives and shall not be deemed exclusive of any other rights to which a Company Indemnified Party is entitled, whether pursuant to Law, contract or otherwise. In the event that the Buyer or the Company or any Company Subsidiary (following the Closing) or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, the Buyer shall use commercially reasonable efforts to cause the successors or assigns of the Buyer or the Company or any Company Subsidiary (following the Closing), as the case may be, to succeed to the obligations set forth in this Section 7.6.

Section 7.7 Termination of Affiliate Obligations. On or before the Closing Date, except as set forth on Schedule 7.7, all liabilities and obligations between the Company or any Company Subsidiary, on the one hand, and one or more of its Affiliates (including the Seller and the Guarantor but not including the Company Subsidiaries) on the other hand, shall be terminated in full, without any liability for the Company or any Company Subsidiary thereof following the Closing.

Section 7.8 Waiver of Conflicts Regarding Representation. Recognizing that Paul, Weiss, Rifkind, Wharton & Garrison LLP (“Paul, Weiss”) has acted as legal counsel to Seller and its Affiliates and may be deemed to have acted as legal counsel to the Company and the Company Subsidiaries prior to the Closing, and that Paul, Weiss intends to act as legal counsel to the Seller and its Affiliates after the Closing, the Company hereby waives, on its own behalf and agrees to cause the Company Subsidiaries to waive, any conflicts that may arise as a result of such previous representation in connection with Paul, Weiss representing the Seller and its Affiliates after the Closing.

Section 7.9 Seller Guarantees of Assumed Indebtedness. The parties hereto acknowledge that on or prior to the Closing, the Seller or its Affiliates, at their sole cost and expense, shall cause any guarantee by the Seller or its Affiliates of any Assumed Indebtedness (each a “Seller Guarantee”) to be released. At Seller’s request and sole cost and expense, the Buyer will use commercially reasonable efforts to cooperate with the Seller’s efforts to secure such releases.

Section 7.10 Pre-Closing Insurance. The parties agree that the Buyer shall not have the benefit of or access to any insurance policies, including the self-insurance programs maintained by the Seller or any of its Affiliates.

Section 7.11 Termination of Services. The Buyer acknowledges that the Company and the Company Subsidiaries currently receive or benefit from certain shared management and administrative and corporate services and benefits provided by the Seller and its Affiliates, including management, operations and information technology, customer service, finance, accounting and payroll and back office services and processing, financial systems, treasury services (including banking, insurance, administration, taxation and internal audit), office space, facilities and office management services, business development and marketing services, product support services, procurement services, risk management, corporate communications, general administrative services, executive and management services, legal services, human resources and personnel services and travel services. Other than as may be provided pursuant to the terms of the Transition Services Agreement, the Buyer further acknowledges that all such services and benefits shall cease, and any agreement in respect thereof shall terminate as of the Closing Date, and thereafter, the Seller’s and its Affiliates sole obligation with respect to the provision of any services to the Company and the Company Subsidiaries shall be as set forth in the Transition Services Agreement.

Section 7.12 Tax Matters. The following provisions shall govern the allocation of responsibility between the Buyer and the Seller for certain Tax matters following the Closing Date.

(a) Straddle Periods. In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income, gross or net sales, payments or receipts, or payroll of the Company and the Company Subsidiaries for the Pre-Closing Taxable Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date (and for such purpose, the taxable period of any partnership or other pass-through entity shall be deemed to terminate at such time) and the amount of any other Taxes of the Company and the Company Subsidiaries for the portion of a Straddle Period that ends on and includes the Closing Date shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period; provided, however, that exemptions, allowances, deductions or Taxes that are calculated on an annual basis, such as property Taxes and depreciation deductions, shall be apportioned between such two taxable years or periods on a daily basis. For the avoidance of doubt, if the Company

or any Company Subsidiary is a “United States shareholder” (within the meaning of Section 951(b) of the Code) of a controlled foreign corporation (within the meaning of Section 957 of the Code), amounts, if any, included in the income of the Company or such Company Subsidiary (as applicable) under Section 951 of the Code with respect to any Straddle Period of the controlled foreign corporation shall be allocated between such two taxable years or periods of the Company or such Company Subsidiary (as applicable) by assuming that, for purposes of Section 951 of the Code, the Straddle Period of the controlled foreign corporation consisted of two taxable years or periods, one of which ended at the close of the Closing Date and the other of which began at the beginning of the day following the Closing Date. In the case of any taxable period that begins before and ends after the Reference Date (a “Straddle Reference Date Period”), Taxes will be apportioned to the Pre-Reference Date Taxable Period in the same manner as Taxes are apportioned to the Pre-Closing Taxable Period in the case of a Straddle Period.

(b) Cooperation. The Buyer, the Company, the Company Subsidiaries, and the Seller shall cooperate fully in connection with the preparation and filing of Tax Returns and any audit, litigation, or other Proceeding with respect to Taxes, and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this Section 7.12(b). Such cooperation shall include the retention and (upon the Buyer or the Seller’s request, as applicable) the provision of records and information that are reasonably relevant to any such audit, litigation or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. In addition, each party shall promptly notify the other party in writing of any demand, claim or notice of the commencement of an audit received by such party from any Governmental Authority or any other Person with respect to Taxes for which such other party may be liable. Any information obtained under this Section 7.12(b) (including, for the avoidance of doubt, any information provided pursuant to the following sentence) shall be kept confidential, except as may be necessary in connection with the filing of a Tax Return or a Tax proceeding. Notwithstanding anything to the contrary, nothing in this Agreement shall permit or be deemed to permit the Buyer or any of its Affiliates or representatives to review or otherwise have access to a Tax Return of any Affiliated Group that includes the Seller or any of its Affiliates; provided, however, that a tax adviser to the Buyer shall have access to, and shall have the right to review, any such Tax Return to the extent such Tax Return relates, or is with respect, to the Company or any Company Subsidiary and, in such tax adviser’s judgment, such review is necessary for the determination of any Tax of the Company or any Company Subsidiary, but only in the event such tax adviser confirms that the information on such Tax Return will be maintained in confidence except to the extent required to be disclosed in connection with any Tax contest involving the Company or a Company Subsidiary.

(i) The Seller shall control the conduct, through counsel of its own choosing at its own expense, of any audit, claim for refund, or other administrative or judicial Proceeding with respect to Taxes of the Company or any of the

Company Subsidiaries (any such audit, claim for refund, or Proceeding referred to herein as a “Contest”) relating solely to taxable periods ending on or before the Reference Date, and all Contests with respect to any Tax Return of any Affiliated Group that includes the Seller or any of its Affiliates (other than solely the Company or any Company Subsidiary) (a “Pre-Closing Consolidated Return”); provided, however, that (A) the Seller shall have no right to represent the Company or any Company Subsidiary in any such Contest unless the Seller shall have first notified the Buyer in writing (1) that it will represent the Company and/or any Company Subsidiary in any such Contest and (2) of the identity of counsel chosen by the Seller in connection therewith; (B) the Seller will keep the Buyer reasonably informed concerning the progress, developments and events of such Contest; (C) the Seller will provide to the Buyer copies of all correspondence and other documents relevant to such Contest to the extent related to the Company or any Company Subsidiary; and (D) the Seller will not settle, compromise and/or concede (or permit or cause any Person to settle, compromise and/or concede) any portion of such Contest that is reasonably likely to affect (1) the Tax liability or (2) any Tax attribute, including but not limited to any net operating loss, net operating loss carryforward or tax credit, in each case, of the Company or any Company Subsidiary after the Reference Date without the prior written consent of the Buyer, which consent will not be unreasonably withheld, conditioned or delayed. The Buyer will have the right to participate in the defense of any such Contest (which will include participation in meetings with taxing authorities and reviewing and commenting on written submissions to taxing authorities) and to employ counsel, at its own expense, separate from the counsel employed by the Seller; provided that in the case of a Contest that relates to a Pre-Closing Consolidated Return, the Buyer shall only have the right to participate in the portion of such Contest, if any, that relates to the Company or any Company Subsidiary. With respect to any such Contest other than a Contest that relates to a Pre-Closing Consolidated Return (x) involving Tax matters or items that could reasonably be expected to form the basis for a claim of indemnification against the Seller pursuant to Section 7.12(j), and (y) that the Seller does not or cannot elect to control pursuant to this Section 7.12(c)(i), the Buyer will control such Contest, including the defense and settlement thereof; provided, however, that the Buyer will: (1) keep the Seller reasonably informed concerning the progress, developments and events of such Contest, (2) provide to the Seller copies of all correspondence and other documents relevant to such Contest, and (3) not settle, compromise and/or concede any such Contest without the prior written consent of the Seller, which consent will not be unreasonably withheld, conditioned or delayed, and the Seller will have the right to participate in the defense of any such Contest (which will include participation in meetings with taxing authorities and reviewing and commenting on written submissions to taxing authorities) and to employ counsel, at its own expense, separate from the counsel employed by the Buyer.

(ii) In the case of a Contest not described in Section 7.12(c)(i) that relates to a Straddle Reference Date Period, the Buyer shall control the conduct of such Contest, but the Seller shall have the right to participate in such Contest at its own expense. Neither the Buyer nor the Company nor any of the Company Subsidiaries shall settle, compromise and/or concede such Contest, to the extent it relates to any Pre-Reference Date Taxable Period, without the prior written consent of the Seller, which consent shall not be unreasonably withheld, delayed or conditioned. If the Buyer

fails to assume control of the conduct of any such Contest within a reasonable period following the receipt by the Buyer of notice of such Contest, the Seller shall have the right to assume control of such Contest; provided, however, that the Seller will: (1) keep the Buyer reasonably informed concerning the progress, developments and events of such Contest, (2) provide to the Buyer copies of all correspondence and other documents relevant to such Contest, and (3) not settle, compromise and/or concede such Contest without the prior written consent of the Buyer, which consent will not be unreasonably withheld, conditioned or delayed.

(d) Close of Tax Year. The parties hereto shall, to the extent permitted or required under applicable Law, treat the Closing Date as the last day of the taxable period of the Company and the Company Subsidiaries for all Tax purposes.

(e) Seller-Filed Tax Returns. The Seller shall prepare or cause to be prepared all income or franchise Tax Returns of the Company and the Company Subsidiaries with respect to tax periods ending on or prior to the Closing Date, including all Straddle Periods (but, in the case of Tax Returns for Straddle Periods, only with respect to Tax Returns of any Affiliated Group that includes the Seller or any of its Affiliates other than solely the Company or any Company Subsidiary)) and all Tax Returns of the Company and the Company Subsidiaries that are required to be filed on or before the Closing Date (together, “Seller Returns”), and the Seller shall remit or cause to be remitted any Taxes due in respect of such Seller Returns. All such Seller Returns shall be timely prepared in a manner consistent with the past practice of the Company and the Company Subsidiaries, unless otherwise required by applicable Law. The Seller shall submit each of the Seller Returns (but only to the extent related to the Company or any Company Subsidiary) that is required to be filed after the Closing Date to the Buyer at least thirty (30) days prior to the date on which such Tax Return is required to be filed (or, if such due date is within thirty (30) days following the Closing Date, as promptly as practicable following the Closing Date) (including extensions) in the case of income Tax Returns and, in the case of any other Tax Returns, within a reasonable period of time prior to the due date (including extensions), and the Buyer shall have the right to review and comment on the Seller Returns. If the Buyer disputes any item on any such Tax Return, it shall notify the Seller of such disputed item (or items) and the basis for its objection. The parties shall act in good faith to resolve any such dispute prior to the date on which the relevant Tax Return is required to be filed. If the parties cannot resolve any disputed item, the item in question shall be resolved by an independent accounting firm mutually acceptable to the Seller and the Buyer. The fees and expenses of such accounting firm shall be borne equally by the Seller and the Buyer. The Buyer shall reimburse the Seller for any Taxes with respect to any Straddle Reference Date Period for which the Seller is not responsible pursuant to Section 7.12(j) shown as due on such Seller Returns as finally determined pursuant to this Section 7.12(e) upon written request setting forth in reasonable detail the computation of the amount owed by the Buyer. Each such reimbursement shall be made no more than the later of ten (10) days after the date upon which such request was made (or, if later, the date on which any dispute is resolved in accordance with this Section 7.12(e)) or three (3) days before the due date of the relevant Seller Return.

(f) Other Tax Returns. Except for the Seller Returns, the Buyer shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company and the Company Subsidiaries the due date of which (taking into account valid extensions of time to file) is after the Closing Date (“Buyer Returns”). All such Buyer Returns relating to a Straddle Reference Date Period shall be prepared timely in a manner consistent with the past practice of the Company and the Company Subsidiaries unless otherwise required by applicable Law. The Buyer shall submit each of the Buyer Returns relating to a Straddle Reference Date Period to the Seller at least thirty (30) days prior to the date on which such Tax Return is required to be filed (or, if such due date is within thirty (30) days following the Closing Date, as promptly as practicable following the Closing Date) (including extensions) in the case of income Tax Returns and, in the case of any other Tax Returns, within a reasonable period of time prior to the due date (including extensions), and the Seller shall have the right to review and comment on such Buyer Returns. If the Seller disputes any item on any such Tax Return, it shall notify the Buyer of such disputed item (or items) and the basis for its objection. The parties shall act in good faith to resolve any such dispute prior to the date on which the relevant Tax Return is required to be filed. If the parties cannot resolve any disputed item, the item in question shall be resolved by an independent accounting firm mutually acceptable to the Buyer and the Seller. The fees and expenses of such accounting firm shall be borne equally by the Buyer and the Seller. The Seller shall reimburse the Buyer Indemnitees for any Taxes with respect to any Pre-Closing Taxable Period for which the Seller is responsible pursuant to Section 7.12(j) shown as due on such Buyer Returns, as finally determined pursuant to this Section 7.12(f), upon written request setting forth in reasonable detail the computation of the amount owed by the Seller. Each such reimbursement shall be made no more than the later of ten (10) days after the date upon which such request was made (or, if later, the date on which any dispute is resolved in accordance with this Section 7.12(f)) or three (3) days before the due date of the relevant Buyer Return. For the avoidance of doubt, the limitations on the liability of the Seller set forth in Article 11 shall not apply to the reimbursement obligations under this Section 7.12(f).

(g) No Amended Tax Returns. Except as required by Law, none of the Seller, the Buyer or any of their respective Affiliates (including after the Closing, the Company or any Company Subsidiary) shall amend, refile or otherwise modify any Tax Return relating to the Company or any Company Subsidiary with respect to any Pre-Closing Taxable Period, nor any Straddle Period, without the other party’s written consent, which shall not be unreasonably withheld, conditioned or delayed; provided, that the Seller and its Affiliates may amend, refile or otherwise modify any such income or franchise Tax Return that is a consolidated, affiliated, combined, unitary or similar Tax Return, provided, however, that none of the Seller or any of its Affiliates shall amend, refile or otherwise modify any such income or franchise Tax Return to the extent that such amendment, refiling or other modification, taken together with all other amendments, refilings and other modifications of any such Tax Returns, will reduce any federal income tax net operating loss carryforward of the Company or any Company Subsidiary existing on the Closing Date (without taking into account the impact of the Transactions, including the Internal Reorganization) by more than $25.0 million after the Closing Date, without the prior written consent of the Buyer, which consent will not be

unreasonably withheld, conditioned or delayed. Between the date of this Agreement and the Closing Date, none of the Seller nor any of its Affiliates shall utilize in its consolidated federal income Tax Return any of the net operating loss carryforwards of Mavenir Systems, Inc. and its subsidiaries at the time Seller acquired Mavenir Systems, Inc., other than in connection with the Transactions (including the Internal Reorganization) or in the ordinary course of business.

(h) Information to be Provided by the Buyer. With respect to any taxable year of the Company or any Company Subsidiary for which the Seller is required to file a Tax Return pursuant to Section 7.12(e), the Buyer shall promptly cause the Company to prepare and provide to the Seller a package of tax information materials (the “Tax Package”), which shall be completed in accordance with the past practice of the Company or the relevant Company Subsidiary including past practice as to providing the information, schedules and work papers and as to the method of computation of separate taxable income or other relevant measure of income. The Buyer shall cause the Tax Package for the portion of the taxable period ending on the Closing Date to be delivered to the Seller within one hundred twenty (120) days after the Closing Date.

(i) Limitation on Actions; Certain Elections.

(i) Without the prior written consent of the Seller, the Buyer will not, and will not permit any of its Affiliates (including, after the Closing, the Company and the Company Subsidiaries) to, make or initiate any voluntary contact with any Governmental Authority with respect to any Pre-Reference Date Taxable Period or any Straddle Reference Date Period, including pursuant to any voluntary disclosure agreement, or make any other voluntary contact with any Governmental Authority, in each case if such action could reasonably be expected to increase the Tax liability of the Seller or any of its Affiliates or to result in an indemnification obligation under Section 7.12(j); provided, however, (A) to the extent that the Seller refuses to provide such written consent, any mitigation obligation of the Buyer or any other Indemnified Party described in Section 11.2 with respect to the matters for which the Seller has not provided such written consent will be deemed to be satisfied and none of the Seller or any of its Affiliates will take any inconsistent position that they have so failed to mitigate in any Proceeding and (B) such limitations described in this Section 7.12(i)(i) shall not apply to any voluntary disclosure agreement or any other voluntary contact by the Buyer or any of its Affiliates with any Governmental Authority with respect to any Tax year or Tax period beginning after the Reference Date if the Buyer Indemnitees shall have waived in writing their right to any indemnification obligation hereunder with respect to the specific Tax which is the subject of such voluntary disclosure or other voluntary contact.

(ii) The Seller agrees that it will not make any election pursuant to Treasury Regulations Section 1.1502-36(d)(6) to reattribute any portion of the attributes of the Company referred to in Treasury Regulations Section 1.1502-36(d)(6)(i)(B). The Seller agrees to make a proper election pursuant to Treasury Regulations Section 1.1502-95(c) to apportion all of any Code Section 382 limitations that apply to the loss subgroup consisting of the Company and the Company Subsidiaries,

and each element thereof (the value element, the adjustment element and the net unrealized built-in gain), to the Company’s loss subgroup (as such terms are used in Treasury Regulations Section 1.1502-95(c)). The Buyer shall provide to the Seller drafts of the form or forms of such election and the agreement required by Treasury Regulations Section 1.1502-95(f)(1)(ii) at least thirty (30) days prior to the time such election is filed. The Seller and the Buyer shall cooperate to resolve any suggested changes to such draft that are submitted by the Seller, which shall be provided to the Buyer within fifteen (15) days after the Seller receives such drafts.

(j) Seller Indemnification. Except to the extent taken into account in the calculation of Final Working Capital, from and after the Closing Date, the Seller shall hold harmless and indemnify each of the Buyer Indemnitees from and against any Losses suffered or incurred by any of the Buyer Indemnitees arising out of, involving, relating to, connected with, or otherwise in respect of: (i) any inaccuracy in or breach of any Specified Representation; (ii) without duplication, Taxes imposed on the Company or any Company Subsidiary, or for which the Company or any Company Subsidiary may otherwise be liable, for any Pre-Closing Taxable Period; and (iii) the items of Tax disclosed on Schedule 7.12(j); provided that, notwithstanding anything in this Agreement to the contrary, (w) the Seller shall not have any indemnification obligation pursuant to clause (i) or clause (ii) of this Section 7.12(j) in respect of Losses described in such clauses to the extent such Losses are in respect of Taxes described in clause (iii) of this Section 7.12(j), (x) the Seller shall not have any indemnification obligation in respect of Losses arising under clause (i) of this Section 7.12(j), to the extent such Losses are recoverable under the Representations and Warranties Insurance Policy or any amended or replacement policy with such Losses deemed as if such Losses are the last Losses submitted and resolved under the Representations and Warranties Insurance Policy or any amended or replacement policy, (y) the Seller shall not have any indemnification obligation in respect of Losses for Taxes described in clause (ii) of this Section 7.12(j) to the extent such Losses also arise under clause (i) of this Section 7.12(j) (even if such Losses are recoverable under the Representations and Warranties Insurance Policy or any amended or replacement policy) and (z) the Seller shall not have any indemnification obligation in respect of Losses attributable to Taxes relating to any taxable period (or portion thereof) after the Reference Date, other than in respect of Taxes of the Seller or any of its Affiliates (other than the Company or any Company Subsidiary) for any Pre-Closing Taxable Period (the “Post-Reference Date Taxes”). For the avoidance of doubt, the Seller’s obligations under any of clause (i), clause (ii) or clause (iii) of this Section 7.12(j) shall not be reduced by the Deductible or by the application of a retention amount pursuant to the Representations and Warranties Insurance Policy. Notwithstanding any other provision of this Agreement, in no event shall the Seller’s aggregate liability under this Section 7.12(j) exceed the amount equal to (i) $350 million minus (ii) all amounts paid or payable by the Seller or the Guarantor under Article 11. The parties agree that for purposes of this Section 7.12(j), Losses (or any portion thereof) that are not explicitly excluded from coverage under the Representations and Warranties Insurance Policy or any amended or replacement policy are recoverable until the Buyer Indemnitees shall have expended commercially reasonable efforts to recover such Losses under the Representations and Warranties Insurance Policy or any amended or replacement policy, and it has been finally

determined that the claim in respect of such Losses (or any portion thereof) has been denied.

(k) Any Tax Sharing Agreement between the Company or any Company Subsidiary, on the one hand, and any other Person, on the other hand, shall be terminated as to the Company or such Company Subsidiary on or prior to the Reference Date, and after the Reference Date none of the Company or any Company Subsidiary shall have any liability thereunder. Any power of attorney with respect to Taxes relating to the Company or any Company Subsidiary granted by any of the Seller, the Company or any Company Subsidiary shall be terminated on or prior to the Closing.

(l) Consideration. The parties hereto agree to treat the payments of the Mitel Units and Investments Note as taxable consideration, the value of each of which shall be as reasonably agreed in writing by the Buyer and the Seller on or before the Closing Date, received by the Seller in connection with the Acquisition, and to take no Tax position inconsistent with such treatment, except as otherwise required by a change in applicable Law or a good faith resolution of a Contest.

(m) The Seller will be entitled to any refunds (or credits in lieu of refunds) (including interest received thereon) of Taxes of the Company or any Company Subsidiary in respect of any Pre-Reference Date Taxable Period or the portion of any Straddle Reference Date Period ending on or before the Reference Date, except to the extent such amounts are included as assets in Final Working Capital; provided, however, the Seller shall not be entitled to any refund of, or credit with respect to, Taxes of the Company or any Company Subsidiary that results from the carryback of losses, credits or similar items by the Seller or an Affiliate of the Seller (except, for the avoidance of doubt, with respect to refunds or credits resulting from a Tax Return of any Affiliated Group that includes the Seller or any of its Affiliates). The Buyer shall cause such refund or the amount of such credit to be paid to the Seller promptly after it is received, allowed or applied against any Tax liability.

(n) Buyer Indemnification. The Buyer shall hold harmless and indemnify each of the Seller Indemnitees from and against any Losses suffered or incurred by any of the Seller Indemnitees arising out of, involving, relating to, connected with or otherwise in respect of the Post-Reference Date Taxes. The parties agree that the utilization of any net operating loss carryforward shall not be considered a Loss for purposes of this Section 7.12(n).

(o) The parties agree that the principal amount of the Investments Note shall be automatically increased, without any action required by any Person, by the aggregate amount of any indemnification payments made by or on behalf of the Seller or its Affiliates pursuant to clause (iii) of Section 7.12(j).

Section 7.13 FIRPTA Certificate. The Seller shall deliver to the Buyer at the Closing a certificate or certificates, in compliance with Treasury Regulations Section 1.1445-2, certifying that the transactions contemplated hereby are exempt from withholding under Section 1445 of the Code.

Section 7.14 Audit of Financial Statements. If the Buyer or any of its Affiliates retain an independent accounting firm to audit all or part of the Financial Statements (an “Audit”), at the Buyer’s request the Seller and the Guarantor shall, and shall, subject to applicable Law, cause their Affiliates to, reasonably cooperate with the Buyer and its authorized representatives in connection with the preparation of an Audit including by providing Buyer with reasonable access to the books and records of the Seller, the Guarantor, the Company and the Company Subsidiaries in connection with the Audit; provided, however, that any such cooperation shall not unreasonably interfere with the business or operations of the Seller or its Affiliates. Notwithstanding anything to the contrary in this Agreement, neither the Seller nor any of its Affiliates shall be required to disclose any information to the Buyer, or its authorized representatives, if doing so could violate any Contract to which the Seller or any of its Affiliates is a party or to which the Seller or any of its Affiliates is subject, provided, however, that the Company shall use all commercially reasonable efforts to seek waivers to provide such information and shall provide redacted copies of such information to the extent permissible if waivers cannot be obtained. The Buyer shall be solely responsible for all costs and expenses arising from or related to an Audit, and the Buyer shall promptly reimburse the Seller, the Guarantor and their Affiliates for all reasonable out-of-pocket costs and expenses incurred by them at the Buyer’s request in connection with an Audit. Any information about the Seller, the Guarantor and their Affiliates (excluding, after the Closing, the Company and its Subsidiaries) provided to or obtained by the Buyer or its authorized representatives pursuant to this Section 7.14 shall be Evaluation Material (subject to the exclusions set forth in the Confidentiality Agreement) and shall be held by the Buyer in accordance with and be subject to the terms of the Confidentiality Agreement. The parties agree that neither the Seller nor its Affiliates shall have any liability whatsoever for any adjustment to the Financial Statements after the date hereof arising out of or related to an Audit or for any Losses arising out of or related to an Audit unless such liability or Loss is for a breach of a representation, warranty or covenant under this Agreement; provided that nothing in this sentence is intended to limit or modify the representations and warranties contained in this Agreement or any Buyer Indemnified Party’s right to indemnification under this Agreement.

Section 7.15 Name and Logo Change.

(a) The Buyer hereby agrees to (i) change the legal names and logos of the Company and the Company Subsidiaries to names and logos that do not contain, are not derived from, and are not confusingly similar to “Mitel” or any other trademarks, service marks, trade names, brand names, logos, trade dress, design rights or other similar designations of source, sponsorship, association or origin owned by Seller (the “Seller Marks”) and (ii) use reasonable best efforts to remove any reference to, including from any signs, products, equipment, literature and business materials (including schedules, inventories, periodic statements, packaging materials and similar forms), any of the Seller Marks, in each case, as promptly as possible but in any event no later than one hundred and twenty (120) days following the Closing Date and to otherwise cease any use of the Seller Marks from and after the Closing.

(b) The Seller and Guarantor hereby agree, on behalf of themselves and their Subsidiaries, to (i) change the legal names and logos of the Seller, the Guarantor and each of their applicable Subsidiaries to names and logos that do not contain, are not derived from, and are not confusingly similar to the Mavenir Trademarks or any other trademarks, service marks, trade names, brand names, logos, trade dress, design rights or other similar designations of source, sponsorship, association or origin owned by Buyer after the Closing (the “Buyer Marks”) and (ii) use reasonable best efforts to remove any reference to, including from any signs, products, equipment, literature and business materials (including schedules, inventories, periodic statements, packaging materials and similar forms), any of the Buyer Marks, in each case, as promptly as possible but in any event no later than one hundred and twenty (120) days following the Closing Date and to otherwise cease any use of the Buyer Marks from and after the Closing.

(c) Except as provided in Section 7.15(a) and (b), the parties agree that neither party has a license to use any of the trademarks, service marks, trade names, brand names, logos, trade dress, design rights or other similar designations of source, sponsorship, association or origin owned by the other party, and each party retains full rights to enforce its rights in the foregoing.

Section 7.16 Internal Reorganization. At the request of the Buyer, the Seller and the Company shall initiate the internal reorganization transactions set forth in Schedule 7.16 (the “Internal Reorganization”) in accordance therewith and take reasonable steps to allow the Internal Reorganization to be consummated immediately prior to the Closing; provided, however, the Seller and the Company shall not be required to effect the Internal Reorganization unless the Buyer shall have waived or confirmed in writing the satisfaction of all conditions set forth in Article 8 and shall have confirmed in writing that the Buyer is prepared to immediately proceed, following completion of the Internal Reorganization, to consummate the Closing. Subject to the proviso in the preceding sentence, the Seller and the Company agree to reasonably cooperate with the Buyer with respect to effectuating the Internal Reorganization immediately prior to the Closing; provided, that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and the Company Subsidiaries.

(b) Notwithstanding anything to the contrary in this Agreement, if the Reverse Termination Fee is payable, then the Seller’s, the Guarantor’s, the Company’s and their respective Related Persons’ sole and exclusive remedy (whether at law, in equity, in contract, in tort or otherwise) against the Buyer, its Related Persons, the Debt Financing Sources, and their respective assignees for any breach, loss or damage shall be to receive payment of the Reverse Termination Fee and any additional amounts payable pursuant to Section 10.3(a) and none of the Buyer, its Related Persons, the Debt

Financing Sources or their respective assignees will have any liability or obligation to the Seller, the Guarantor, the Company or any of their Related Persons relating to or arising out of this Agreement or in respect of any other document or theory of law or equity or in respect of any oral representations made or alleged to be made in connection herewith or therewith, whether at law or equity, in contract, in tort or otherwise. If the Closing does not occur for any reason whatsoever, the Buyer shall in no event be liable to the Seller, the Guarantor or the Company in the aggregate for any amount in excess of the Reverse Termination Fee and any additional amounts payable pursuant to Section 10.3(a). Each of the Seller, the Guarantor and the Company hereby covenants and agrees that it shall not, and shall cause the Company Subsidiaries not to, institute any proceeding or bring any other claim arising under, or in connection with, this Agreement, the Financing Commitments, the Limited Guarantee or the negotiation, execution, performance, abandonment or termination of the Transactions (whether at law or in equity, under any theory of liability (including without limitation by attempting to pierce a corporate, limited liability company or partnership veil)) against the Buyer or any Related Person of the Buyer except for claims: (i) against the Buyer or Investments in accordance with and pursuant to the terms of this Agreement; (ii) against the parties to the Limited Guarantee, subject to the terms and limitations thereof; (iii) against the parties to the Equity Commitment Letter for specific performance of their respective obligations under the Equity Commitment Letter, subject to the terms and limitations thereof if, and only if, the conditions of Section 13.14(b) (in case of the foregoing, other than those conditions that by their nature are to be satisfied at the Closing) have been satisfied (or waived); and (iv) against Xura, Inc. under the Confidentiality Agreement, subject to the terms and limitations thereof (the claims described in clauses (i) through (iv) collectively, the “Retained Claims”).

In furtherance and not in limitation of the foregoing waiver, it is agreed that no Debt Financing Source Related Party shall have any liability for any claims, losses, settlements, damages, costs, expenses, fines or penalties to the Seller, the Guarantor or the Company (or any of its current and future Related Persons) in connection with this Agreement or the Transactions. Notwithstanding the foregoing, nothing in this Section 10.3(c) shall in any way limit or modify the rights and obligations of the Buyer under the Debt Commitment Letter.

The party seeking indemnification shall use commercially reasonable efforts to mitigate any Loss which forms the basis of an indemnification claim hereunder.

Section 11.3 Survival of Representations, Warranties, Covenants and Agreements; Termination of Indemnification. The representations, warranties and the covenants and agreements contained herein and in any certificate delivered pursuant hereto shall survive the Closing as follows: (a) subject to clause (b) below, the covenants and agreements contained herein shall not terminate; and (b) the Seller Fundamental Representations, the Specified Representations, the Buyer Fundamental Representations and the covenants set forth in Section 7.12(j) (other than the covenant set forth in clause (iii) of Section 7.12(j)) shall survive for six (6) years after the Closing; (c) the Seller Representations shall survive (i) for twelve (12) months after the Closing for all purposes of this Agreement, and (ii) until the expiration of the term of the Representations and Warranties Insurance Policy for purposes of the Representations and Warranties Insurance Policy; (d) all representations and warranties of the Buyer (other than the Buyer Fundamental Representations) shall survive for twelve (12) months after the Closing; and (e) the covenant set forth in clause (iii) of Section 7.12(j) shall survive for twelve (12) months after the Closing. The obligations to indemnify and hold harmless any party (A) pursuant to Section 11.1(a)(i) and Section 11.1(b)(i) shall terminate when the applicable representation or warranty terminates in accordance with this Section 11.3, and (B) pursuant to the other clauses of Section 11.1(a) and Section 11.1(b) shall not terminate; provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the Indemnified Party shall have, before the expiration of the applicable period, made a claim by delivering a notice of such claim in accordance with Section 11.4 to the Indemnifying Party or, in the case of any obligation to indemnify under Section 7.12(j), with respect to any item as to which the Indemnified Party shall have, before the expiration of the applicable period, properly made a claim in good faith under the Representations and Warranties Insurance Policy or any amended or replacement policy.

Section 11.4 Procedures.

(a) Third Party Claims. In connection with a claim made by any Person not a party hereto (other than Buyer Indemnified Parties or Seller Indemnified Parties) against a Buyer Indemnified Party or a Seller Indemnified Party (an “Indemnified Party”) pursuant to which an Indemnified Party may be entitled to any indemnification provided for under Section 11.1 (a “Third Party Claim”), such Indemnified Party shall notify the indemnifying party (the “Indemnifying Party”) in writing of such Third Party Claim (setting forth in reasonable detail the facts giving rise to such Third Party Claim (to the extent known by the Indemnified Party) and the amount or estimated amount (to the extent reasonably estimable) of Losses arising out of, involving or otherwise in respect of such Third Party Claim) within twenty (20) Business Days after receipt by such Indemnified Party of written notice of such Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent that the Indemnifying Party has been actually prejudiced as a result of such failure.

(b) Assumption. If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and if it so chooses, to assume the defense thereof with counsel selected by the

Indemnifying Party and reasonably acceptable to the Indemnified Party; provided, that the Indemnifying Party shall not be entitled to assume the defense thereof if (i) the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its willingness to defend such Third Party Claim, (ii) the Third Party Claim is a criminal Proceeding, or relates to such a Proceeding, or (iii) such Third Party Claim may be covered by the Representations and Warranties Insurance Policy or any amended or replacement policy even if the Losses are not expected to exceed the retention under such Representations and Warranties Insurance Policy. If the Indemnifying Party assumes the defense of a Third Party Claim in accordance with this Section 11.4(b), the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, provided that the Indemnified Party shall have the right to employ one (1) counsel to represent such Indemnified Party (plus one (1) local counsel in each applicable jurisdiction) if the Indemnified Party and the Indemnifying Party are both named parties to the Proceedings and the Indemnified Party determines in good faith and upon advice of outside legal counsel that joint representation would be inappropriate due to actual or potential differing interests between them, and in that event the reasonable fees and expenses of such separate counsel for the Indemnified Party shall be paid by the Indemnifying Party. Any such participation or assumption shall not constitute a waiver by any party of any attorney-client privilege in connection with such Third Party Claim. If the Indemnifying Party assumes the defense of a Third Party Claim in accordance with this Section 11.4(b), the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, then the Indemnifying Party and all of the Indemnified Parties shall reasonably cooperate in the defense or prosecution thereof. If notice is given to an Indemnifying Party of a Third Party Claim in accordance with this Section 11.4(b) and the Indemnifying Party does not, within twenty (20) Business Days after such notice is given, give notice to the Indemnified Party of its election to assume the defense of such Third Party Claim in accordance with this Section 11.4(b), the Indemnifying Party will be bound by any determination made in such Third Party Claim or any settlement, compromise or discharge effected by the Indemnified Party. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnifying Party shall not settle such Third Party Claim without the consent of the Indemnified Party unless such settlement (i) does not involve any finding or admission of any violation of Law or any violation of the rights of any Person, (ii) does not involve any relief other than monetary damages that are paid in full by the Indemnifying Party (iii) does not require the consent of the insurance policy provider pursuant to the Representations and Warranties Insurance Policy and (iv) completely, finally and unconditionally releases the Indemnified Party in connection with such Third Party Claim.

(c) If the Indemnifying Party chooses to defend any Third Party Claim, the Indemnifying Party shall not, without the prior written consent of the Indemnified Party, cause, or agree to, the waiver of the attorney-client privilege, attorney work-product immunity or any other privilege or protection in respect of confidential legal memoranda and other privileged materials drafted by, or otherwise reflecting the

legal advice of, internal or outside counsel of an Indemnified Party (the “Subject Materials”) relating to such Third Party Claim. Each party hereto mutually acknowledges and agrees, on behalf of itself and its Affiliates, that (i) each shares a common legal interest in preparing for the defense of legal proceedings, or potential legal proceedings, arising out of, relating to or in respect of any actual or threatened Third Party Claim or any related claim or counterclaim, (ii) the sharing of Subject Materials will further such common legal interest and (iii) by disclosing any Subject Materials to and/or sharing any Subject Materials with the Indemnifying Party, the Indemnified Party shall not waive the attorney-client privilege, attorney work-product immunity or any other privilege or protection; provided, however, nothing herein shall prohibit an Indemnifying Party that does not choose to defend a Third Party Claim from utilizing Subject Materials to defend itself against a claim by the party seeking indemnification hereunder. The Indemnified Party shall not be required to make available to the Indemnifying Party any information that is subject to an attorney-client or other applicable legal privilege that based on the advice of outside counsel would be impaired by such disclosure or any confidentiality restriction under applicable Law.

(d) Other Claims. In the event any Indemnified Party has a claim against any Indemnifying Party under Section 11.1 that does not involve a Third Party Claim, the Indemnified Party shall deliver notice of such claim to the Indemnifying Party (setting forth in reasonable detail the facts giving rise to such claim (to the extent known by the Indemnified Party) and the amount or estimated amount (to the extent reasonably estimable) of Losses arising out of, involving or otherwise in respect of such claim); provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party has been actually prejudiced as a result of such failure. If the Indemnifying Party does not notify the Indemnified Party within twenty (20) Business Days following its receipt of such notice that the Indemnifying Party disputes its liability to the Indemnified Party under Section 11.1, such claim specified by the Indemnified Party in such notice shall be conclusively deemed a liability of the Indemnifying Party and the Indemnifying Party shall pay the amount of such liability to the Indemnified Party on demand or, in the case of any notice in which the amount of the claim (or any portion thereof) is estimated, on such later date when the amount of such claim (or such portion thereof) becomes finally determined.

(e) Interest. Any amounts due hereunder that are not paid on or before the second (2nd) Business Day after such amounts have been finally determined to be due hereunder shall bear interest at a rate equal to the prime rate as published in the Wall Street Journal, Eastern Edition on the Closing Date.

(f) Coordination with Tax Contests. If there shall be any conflicts between the provisions of this Section 11.4 and Section 7.12, the provisions of Section 7.12 shall control with respect to Tax contests.

Section 11.5 Treatment of Indemnity Payments. Following the Closing, any payment made pursuant to this Article 11 or Section 7.12(j) shall be treated by the parties hereto, for Tax purposes, as an adjustment to the Purchase Price.

Section 11.6 Set-off; Payment. Any payment in excess of the R&W Cap to be made by the Seller or the Guarantor pursuant to this Article 11 or Section 7.12(j) shall be first paid by a dollar for dollar set-off against the Buyer Note unless and until the principal amount owed by Investments thereunder is equal to zero (taking into account the following sentence), second in cash unless and until the aggregate cash payments made by Seller or the Guarantor pursuant to this Article 11 or Section 7.12(j) equal $385 million and third by a forfeiture of Mitel Units with the number of Mitel Units forfeited to be determined based upon the value of the Mitel Units as established pursuant to Section 7.12(l). Set-off against the Buyer Note shall be the exclusive remedy for any Losses for which an Indemnified Party is indemnified under Section 11.1(a)(iv) (but only to the extent the Indemnified Party is seeking indemnification pursuant to Section 11.1(a)(iv) and not any other clause of Section 11.1(a)), and any such set-off shall be deemed to be the first claim for set-off against the Buyer Note.

Section 11.7 Subrogation. In the event of payment by or on behalf of any Indemnifying Party to any Indemnified Party (including pursuant to this Article 11) in connection with any claim or demand by any Person other than the parties hereto or their respective Affiliates, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnified Party as to any events or circumstances in respect of which such Indemnified Party may have any right, defense or claim relating to such claim or demand (except with respect to the insurer(s) under the Representations and Warranties Insurance Policy to the extent such insurer(s) have acknowledged coverage) against any claimant or plaintiff asserting such claim or demand. Such Indemnified Party shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost of such Indemnifying Party, in presenting any subrogated right, defense or claim.

Section 11.8 Exclusive Remedy. Notwithstanding anything to the contrary herein, except in the case of intentional fraud, in connection with a dispute under Section 2.3 (which shall be governed exclusively by Section 2.3(b)), or as provided in Section 7.12(j), or as provided for in Section 7.17, the indemnification provisions of Article 11 and the Representations and Warranties Insurance Policy (or any amended or replacement policy) shall be the sole and exclusive remedy of the parties following the Closing for any and all breaches or alleged breaches of any representations, warranties, covenants or agreements of the parties, or any other provision of this Agreement, the Ancillary Agreements or the Transactions. For the avoidance of doubt, the Buyer hereby acknowledges and agrees that all Losses of the Company and the Company Subsidiaries, other than those for which a Buyer Indemnitee recovers Losses in accordance with

Article 11, Section 7.12(j) or the Representations and Warranties Insurance Policy, shall be the sole responsibility of the Buyer, and after the Closing, the Company and the Company Subsidiaries. In furtherance (and not in limitation) of the foregoing, the Buyer irrevocably covenants to refrain, and to cause its Affiliates to refrain, from directly or indirectly, asserting any claim or demand, or commencing, instituting or causing to be commenced, any Proceeding of any kind against any Related Person of the Seller or the Guarantor (other than the Seller and the Guarantor), based upon, arising out of or relating to this Agreement, the Ancillary Agreements, the Transactions or the organization, management and operation of the business of the Company or any Company Subsidiary on or prior to the Closing Date.

ARTICLE 12

GUARANTY

Section 12.1 Guaranty by Guarantor. Guarantor hereby absolutely and unconditionally guarantees to the Buyer the prompt payment or performance when due, of all of the Seller’s agreements, undertakings and other obligations under this Agreement (collectively, “Obligations”), to the same extent as the Seller has such liability (collectively the “Guaranteed Obligations”). If all or any part of the Guaranteed Obligations shall not be punctually paid or performed by the Seller as and when the same become due in accordance with this Agreement, the Buyer shall provide notice to the Guarantor of such failure, with such notice providing reasonable details regarding the Guaranteed Obligations unfulfilled by the Seller and for which payment or performance is being sought from the Guarantor hereunder. Such demand(s) may be made after the time for payment or performance of all or part of the Guaranteed Obligations is due, but not punctually paid or performed by the Seller, and may be made from time to time with respect to the same or different items of Guaranteed Obligations. All payments made hereunder shall be made without reduction, whether by offset, payment in escrow, or otherwise, except in all cases to the extent of any and all defenses to payment or performance or offset rights which may be available to the Seller.

Section 12.2 Guaranty of Payment, Performance and Collection. This guaranty is a guaranty of payment, performance, and collection. The Guarantor waives any right to require the Buyer to sue the Seller concurrently with, or as a condition precedent to, any suit or action against the Guarantor.

Section 12.3 Consideration and Information. The Guarantor is the owner of 100% of the equity of the Seller, and will derive substantial economic benefit from the Transactions, and the Buyer’s willingness to enter into this Agreement and perform its obligations hereunder, is based, in part, on the Guarantor’s agreements under this Article 12. The Guarantor assumes all responsibility for being and keeping itself informed of the Seller’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that the Guarantor assumes and incurs under this Article 12, and agrees that the Buyer shall not have any duty to advise the Guarantor of information known to the Buyer regarding those circumstances or risks.

Section 12.4 Guarantor Successors and Assigns. If the Guarantor or any of its successors or assigns shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger, and any Guaranteed Obligations remain outstanding, the successors and assigns of the Guarantor shall immediately assume all of the liabilities and obligations of the Guarantor set forth in this Article 12, mutatis mutandis as if set forth in this Article 12 as of the date hereof, without any further action by, or consent required from, the parties or any other Person. The Guarantor shall take, and shall cause its Affiliates to take, all actions necessary or beneficial to give effect to this Section 12.4.

(a) Any matter, information or item disclosed in the Schedules delivered under any specific representation, warranty or covenant or Schedule number hereof, shall be deemed to have been disclosed for all purposes of this Agreement in response to every representation, warranty or covenant in this Agreement in respect of which such disclosure is reasonably apparent on its face. The inclusion of any matter, information or item in any Schedule to this Agreement shall not be deemed to

102

constitute an admission of any liability by the Seller or the Company to any third party or otherwise imply, that any such matter, information or item is material or creates a measure for materiality for the purposes of this Agreement.

(b) The Schedules and Exhibits hereto are hereby incorporated into this Agreement and are hereby made a part hereof as if set out in full in this Agreement.

Section 13.7 Waiver. Waiver of any term or condition of this Agreement by any party shall only be effective if in writing and shall not be construed as a waiver of any subsequent breach or failure of the same term or condition, or a waiver of any other term or condition of this Agreement.

Section 13.8 Binding Effect; Assignment. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their permitted successors and assigns. No party to this Agreement may assign or delegate, by operation of law or otherwise, all or any portion of its rights, obligations or liabilities under this Agreement without the prior written consent of the other parties to this Agreement, which any such party may withhold in its absolute discretion; provided, that, without the prior written consent of any Person, Buyer may (i) assign and/or transfer any of its rights and obligations hereunder to any Affiliate of Buyer, it being acknowledged and agreed that any such assignment will not relieve Buyer from its obligations under this Agreement, and/or (ii) assign its rights, but not its obligations, hereunder to any of its or its Affiliates’ respective Debt Financing Sources. Any purported assignment without such prior written consents shall be void.

Section 13.9 No Third Party Beneficiary. Nothing in this Agreement shall confer any rights, remedies or claims upon any Person or entity not a party or a permitted assignee of a party to this Agreement, except for (a) the current and former officers, directors and employees of the Company as set forth in Section 7.6, (b) the Releasees as set forth in Section 7.21, (c) Buyer and its Related Persons with respect to Section 10.3, and (d) the Debt Financing Sources with respect to the Debt Financing Source Provisions.

Section 13.10 Counterparts. This Agreement may be signed in any number of counterparts with the same effect as if the signatures to each counterpart were upon a single instrument, each of which when delivered to the other parties (including via facsimile or e-mail portable document format (*.pdf)) will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same Agreement.

Section 13.11 Governing Law and Jurisdiction. This Agreement and any Proceeding hereunder shall be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to the principles of conflict of Laws thereof to the extent such principles would require or permit the application of the Laws of another jurisdiction.

103

Section 13.12 Consent to Jurisdiction and Service of Process. Any Proceeding arising out of or relating to this Agreement or the Transactions may only be instituted in any state or federal court in the State of Delaware, and each party waives any objection which such party may now or hereafter have to the laying of the venue of any such Proceeding and irrevocably submits to the jurisdiction of such court in any such Proceeding.

Section 13.13 Conveyance Taxes. The Buyer agrees to pay all sales, use, value added, transfer, stamp, registration, documentary, excise, real property transfer or similar Taxes incurred as a result of the Transactions and the Seller and the Buyer agree to jointly file all required change of ownership and similar statements. All costs and expenses incurred by the Seller related to the foregoing shall be promptly reimbursed by the Buyer.

Section 13.14 Specific Performance.

(a) Except as set forth in Section 13.14(b), the parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by them in accordance with the terms hereof or were otherwise breached. It is accordingly agreed that, except as set forth in Section 13.14(b), each party hereto shall be entitled to seek an injunction or injunctions in any court of competent jurisdiction to prevent breaches of the provisions hereof and to enforce the specific performance of the terms hereof, in addition to any other remedy at law or equity. Except as set forth in Section 13.14(b), each of the parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. Any party seeking (i) an injunction or injunctions to prevent breaches of this Agreement when expressly available pursuant to the terms of this Agreement or (ii) to enforce specifically the terms and provisions of this Agreement when expressly available pursuant to the terms of this Agreement, shall not be required to provide any bond or other security in connection with any such order or injunction.

(b) Notwithstanding anything herein to the contrary, it is acknowledged and agreed that the Seller, the Guarantor and the Company shall be entitled to obtain specific performance of the Buyer’s and Investments’ obligations to consummate the Transactions if and only in the event that each of the following conditions has been satisfied: (i) all of the conditions set forth in Article 8 have been satisfied or waived (other than those conditions that by their nature are to be satisfied or waived at the Closing), (ii) the Buyer fails to complete the Closing by the date the Closing is required to have occurred pursuant to Section 3.1, (iii) the Debt Financing Sources will make available to the Buyer the full amount of the Debt Financing pursuant to the terms of the Debt Commitment Letter or the definitive debt agreements, as applicable, if the Equity Financing is funded at the Closing and (iv) the Seller, the Guarantor and the Company have irrevocably confirmed in a written notice delivered to the Buyer that if specific performance is granted, then the conditions set forth in Article 9

104

that by their nature are to be satisfied or waived at the Closing will be satisfied promptly and the Closing will occur. For the avoidance of doubt, (1) in no event shall the Company, the Guarantor or the Seller be entitled to force the Buyer in any manner to consummate the Closing if the Debt Financing has not been funded or will not be funded at the Closing and (2) in no event shall the Seller, the Guarantor or the Company be entitled to both specific performance to consummate the Closing and payment of the Reverse Termination Fee.

Section 13.15 Severability. If any term, provision, agreement, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, agreements, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party hereto. Upon such a determination, 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 reasonably acceptable manner so that the Transactions may be consummated as originally contemplated to the fullest extent possible.

Section 13.16 Lender Limitations. Notwithstanding anything to the contrary contained in this Agreement, each of the parties hereto: (i) agrees that it will not bring or support any person in any action, suit, proceeding, cause of action, claim, cross claim or third party claim of any kind or description, whether at Law or in equity, whether in contract or in tort or otherwise, against any of the Debt Financing Sources in any way relating to this Agreement or any of the Transactions, including, but not limited to, any dispute arising out of or relating in any way to the Debt Commitment Letter or the performance thereof or the financings contemplated thereby, in any forum other than the federal and New York state courts located in the Borough of Manhattan within the City of New York, (ii) agrees that, except as specifically set forth in the Debt Commitment Letter, all claims or causes of action (whether at Law, in equity, in contract, in tort or otherwise) against any of the Debt Financing Sources in any way relating to the Debt Commitment Letter or the performance thereof or the financings contemplated thereby, shall be exclusively governed by, and construed in accordance with, the internal Laws of the State of New York, without giving effect to principles or rules or conflict of Laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction, and (iii) hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation (whether in Law or in equity, whether in contract or in tort or otherwise) directly or indirectly arising out of or relating in any way to the Debt Commitment Letter or the performance thereof or the financings contemplated thereby. Notwithstanding anything to the contrary contained in this Agreement, (a) the Seller, the Guarantor, the Company and the Company Subsidiaries, and its and their respective Affiliates, directors, officers, employees, agents, partners, managers, members or stockholders shall not have any rights or claims against any Debt Financing Source, in any way relating to this Agreement, the Debt Financing or any of the Transactions, or in respect of any other document or any of the Transactions, or in respect of any oral or written representations made or alleged to have been made in connection herewith or therewith, including any dispute arising out of or relating in any

105

way to the Debt Commitment Letter or the performance thereof or the financings contemplated thereby, whether at Law or equity, in contract, in tort or otherwise and (b) no Debt Financing Source shall have any liability (whether in contract, in tort or otherwise) to any of the Seller, the Guarantor, the Company and the Company Subsidiaries, and its and their respective Affiliates, directors, officers, employees, agents, partners, managers, members, representatives or stockholders for any obligations or liabilities of any party hereto under this Agreement or for any claim based on, in respect of, or by reason of, the Transactions or in respect of any oral or written representations made or alleged to have been made in connection herewith or therewith, including any dispute arising out of or relating in any way to the Debt Commitment Letter or the performance thereof or the financings contemplated thereby, whether at Law or equity, in contract, in tort or otherwise. Notwithstanding anything to the contrary contained in this Agreement, the Debt Financing Sources are intended third party beneficiaries of, and shall be entitled to the protections of this provision.
