Company and Buyer shall in good faith attempt to resolve any of Buyer’s objections as set forth in Buyer’s Objection Notice, and Company shall make such revisions to the disputed items in the Estimated Closing Statement (as well as corresponding changes to the Payments Certificate) as may be mutually agreed between Company and Buyer.

(b) As promptly as practicable, but in any event within sixty (60) days following the Closing Date, Buyer (on behalf of the Surviving Corporation) shall prepare and deliver to the Sellers’ Representative:

(i) the Closing Date Balance Sheets (the “Final Closing Date Balance Sheets”); and

(ii) a closing statement (the “Final Closing Statement”) setting forth the calculation of the Purchase Price, including the calculation of Adjusted Net Working Capital (the “Final Adjusted Net Working Capital”) and the Per Share Price.

(c) The Sellers’ Representative shall be given reasonable access to all supporting documents and work papers used in the preparation of the Final Closing Date Balance Sheets, Final Closing Statement and calculation of Final Adjusted Net Working Capital as reasonably requested in connection with the matters in Section 2.13(b).

(d) The Sellers’ Representative may dispute any amounts reflected on the Final Closing Date Balance Sheets, the calculation of Final Adjusted Net Working Capital and/or the Final Closing Statement, but only on the basis that the amounts reflected therein were not arrived at in accordance with this Agreement or resulted from a mathematical mistake;provided,however, that the Sellers’ Representative shall have notified Buyer in writing of each disputed item (collectively, the “Disputed Items”), specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute (a “Protest Notice”), within thirty (30) days of Buyer’s delivery of the deliverables specified in Section 2.13(b) to the Sellers’ Representative. To the extent the Sellers’ Representative provides a Protest Notice within thirty (30) days of Buyer’s delivery of the deliverables specified in Section 2.13(b) to the Sellers’ Representative, all items that are not Disputed Items shall be final and binding for all purposes hereunder. In the event the Sellers’ Representative does not provide a Protest Notice to Buyer within thirty (30) days of Buyer’s delivery of the deliverables specified in Section 2.13(b) to the Sellers’ Representative, the Sellers’ Representative shall be deemed to have accepted in full the Final Closing Statement (which sets forth the calculation of the final Purchase Price and the final Per Share Price) and the Final Adjusted Net Working Capital. After receipt by Buyer of a Protest Notice, Buyer and the Sellers’ Representative shall meet by telephone, or at a mutually agreeable

location, to discuss and attempt to reconcile their differences with respect to, and the amounts in respect of, the Disputed Items. If the Sellers’ Representative and Buyer are unable to reach a resolution within thirty (30) days after receipt by Buyer of the Protest Notice, Buyer and the Sellers’ Representative shall within thirty (30) days thereafter submit the remaining Disputed Items for resolution to Deloitte & Touche LLP (or, if such firm declines to act, to another nationally recognized public accounting firm mutually agreed upon by Buyer and the Sellers’ Representative) (the “Independent Accounting Firm”), which shall be instructed by Buyer and the Sellers’ Representative, to determine and report to Buyer and the Sellers’ Representative upon the resolution of such remaining Disputed Items within thirty (30) days after such submission. Each of the Buyer and Sellers’ Representative will be afforded the opportunity to present to the Independent Accounting Firm any material such party deems relevant to the Independent Accounting Firm’s determination. Buyer and Sellers’ Representative shall each furnish to the Independent Accounting Firm such work papers and other documents and information relating to the remaining Disputed Items as the Independent Accounting Firm may request. Notwithstanding anything herein to the contrary, with respect to its determination of each Disputed Item, the Independent Accounting may only decide in favor of the position presented by either Buyer or Sellers’ Representative, and may not make a determination other than in favor of one of the two positions presented with respect to each such Disputed Item. The fees and disbursements of the Independent Accounting Firm shall be allocated between Buyer and the Sellers’ Representative, in the same proportion that the aggregate amount of such remaining Disputed Items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by each such Party (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining Disputed Items so submitted.

(e) The items set forth on the Final Closing Statement, Final Adjusted Net Working Capital and Final Closing Balance Sheets shall be deemed final for the purposes of this Section 2.13 upon the earlier of (i) the failure of Sellers’ Representative to notify Buyer of a dispute within thirty (30) days of Buyer’s delivery of the deliverables specified in Section 2.13(b) to Sellers’ Representative, (ii) the resolution of all Disputed Items pursuant to Section 2.13(d) by Buyer and Sellers’ Representative and (iii) the resolution of all remaining Disputed Items pursuant to Section 2.13(d) by the Independent Accounting Firm (which shall constitute an arbitral award that is final, binding and non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover). The final determinations of such matters shall be non-appealable and incontestable by the Parties and each of their respective Affiliates and successors and assigns and not subject to collateral attack for any reason other than fraud.

(f) In the event that the final Purchase Price as finally determined in accordance with this Section 2.13 is more than the Purchase Price as determined on the Closing Date in accordance with Section 2.9, then the Surviving Corporation shall promptly (but in any event, within three (3) Business Days) pay such difference, together with interest as described below, to the Sellers’ Representative, which amount shall promptly (but in any event, within three (3) Business Days) be distributed by the Sellers’ Representative to each of the Sellers in accordance with its Ownership Percentage. If the Purchase Price as finally determined in accordance with this Section 2.13 is less than the Purchase Price as determined on the Closing Date in accordance with Section 2.9, then the Sellers’ Representative, shall promptly (but in any event, within one (1) Business Day) cause an amount equal to such difference, together with interest as described below, to be distributed to Buyer from the Working Capital Escrow Amount and the balance, if any, from the Indemnification Escrow Amount. All amounts payable pursuant to this Section 2.13(f) shall be paid together with interest thereon from the Closing Date to the date of payment at a floating rate equal to the U.S. dollar prime rate per annum, as quoted by Citibank, N.A. (or any successor thereof) from time to time during such period (with such interest being calculated based on a year of 365 days and the number of days elapsed since the Closing Date). The payment required in this Section 2.13(f) shall be made by wire transfer in immediately available funds.

(g) In the event there is any Tax Refund Consideration or any Tax Savings Consideration as determined pursuant to Section 9.4, then except as otherwise required by Sections 9.4(g), 9.4(h) or 9.4(i) the Surviving Corporation shall promptly pay such consideration to the Sellers’ Representative, which consideration shall promptly be distributed by the Sellers’s Representative to each of the Sellers in accordance with its Ownership Percentage.

(h) The Parties agree that the purpose of preparing the Closing Date Balance Sheets and determining the Adjusted Net Working Capital is to measure changes in the components taken into consideration in determining the final Adjusted Net Working Capital, which components (together with such methodologies and assumptions for determination) were used in the calculation of the Target Working Capital as set forth onAnnex I. The Closing Date Balance Sheets and the Adjusted Net Working Capital shall be determined in accordance withAnnex I and shall not include any judgments, accounting methods, policies, principles, practices, procedures, classifications or estimation methodologies other than as set forth onAnnex I.

(i) In connection with the preparation of the Estimated Closing Statement and the good faith estimate of the Purchase Price pursuant to Section 2.13(a), (i) the Adjusted Net Working Capital and Cash shall be determined based on the Estimated Closing Date Balance Sheets, (ii) the amount of any Indebtedness shall be determined based on the outstanding Indebtedness on the Closing Date and (iii) the amount of any Assumed Clinic Debt shall equal the principal amount thereof plus any accrued interest on the Closing Date. In connection with the preparation of the Final Closing Statement and the determination of the Purchase Price pursuant to Section 2.13(b), (i) the Final Adjusted Net Working Capital and Cash shall be determined based on the Final Closing Date Balance Sheets, (ii) the amount of any Indebtedness shall be determined based on the outstanding Indebtedness on the Closing Date and (iii) the amount of any Assumed Clinic Debt shall equal the principal amount thereof plus any accrued interest on the Closing Date.

(j) Any payments made pursuant to this Section 2.13, including Section 2.13(g), shall be deemed to be an adjustment to the Purchase Price as determined on the Closing Date in accordance with Section 2.9.

5.9Notice of Developments; Supplements to this Disclosure Schedule. To the extent Company has Knowledge of any change or development in respect of events occurring after the date hereof which would cause any of the representations and warranties in Article III above not to be true and correct, Company shall promptly (and in any event, within four (4) Business Days) notify Buyer in writing thereof. No such notification shall affect the representations or warranties of the Company, or the conditions to Buyer’s obligations hereunder.

5.10Indebtedness and Release of Encumbrances; Related Party Transactions.

(a) Except with respect to any Assumed Clinic Debt, on or prior to the Closing, Company shall with the proceeds of the indebtedness issued pursuant to the definitive documentation contemplated by the Debt Commitment Letter, extinguish or cause to be extinguished (i) all Corporate Debt and Aggregate Clinic Subsidiary Debt and any related Encumbrances upon their assets and properties of the Company Entities and (ii) all guarantees by any Company Entities of any such Indebtedness referred to in clause (i).

5.11.Resignations. Company shall, no later than five (5) Business Days prior to the Closing, request each director of the Company identified by Buyer prior to such date to deliver their written resignations to Buyer pursuant to such customary and reasonable form resignation letter as proposed by Buyer.

5.12280G Matters. Prior to the Closing, the Company shall use its reasonable commercial efforts to ensure that the accelerated vesting of any Options, as contemplated hereunder, and the payment of any amounts (whether or not accelerated) to a “disqualified individual” (as defined in Section 280G(c) of the IRC) in connection with the transactions contemplated hereunder, will not result in the disallowance of a deduction to the Company under Section 280G of the IRC, including, as necessary, (i) soliciting the requisite approval of the Stockholders, in a manner that meets the shareholder approval requirements of Section 280G(b)(5) of the IRC and Treasury Regulation Section 1.280G-1, Q/A-7 and (ii) to the extent necessary, obtaining a waiver from each such “disqualified individual” entitled to receive a “parachute payment” (as defined in Section 280G(b) of the IRC) in connection with the transactions contemplated hereunder of his or her right to receive such payment, in the case of clauses (i) and (ii), in form and substance satisfactory to Buyer. The Company shall provide Buyer with drafts of all such solicitation materials and consents for review and comment prior to delivery to Stockholders or disqualified individuals, as applicable. To the extent any payment (other than any payments or benefits due pursuant to (A) the Amended and Restated Employment Agreements for each of Joseph A. Carlucci, Syed T. Kamal, Christopher T. Ford and John McDonough to be effective at the Effective Time and (B) any other new Benefit Plan that is effective at or following the Effective Time) would not be deductible as a result of Section 280G, the Company shall be entitled to recover the value of such lost deductions (excluding any deductions that are Compensation Transaction Deductions) to the Company solely from the Indemnification Escrow Amount. The payment obligation set forth in the previous sentence shall be treated for purposes of this Agreement as if there were a breach of a covenant for which indemnification is available to the Buyer Indemnitees pursuant to Sections 11.2(a)(ii) and 11.2(a)(iii) hereof.

5.13Proceedings. Prior to the Closing, the Company Entities shall consult with Buyer and keep Buyer informed on a timely basis in respect of, and in connection with, the defense of any Proceedings (in which damages in excess of $100,000, or non-monetary or equitable relief, is being sought by one or more parties in the applicable Proceeding) to which any Company Entity (or any assets, rights or properties of any Company Entity) is or threatened to be a party or is otherwise the subject. Such obligations shall include (a) furnishing as promptly as practicable (i) to Buyer notice of all material developments in, or relating to, such Proceedings and (ii) to Buyer and its Affiliates any

information relating to such Proceedings reasonably requested by Buyer, its Affiliates or their respective counsel and other representatives and (b) considering in good faith any requests and/or recommendations of Buyer or its Affiliates with respect to such Proceedings;provided, that, the foregoing shall not alter or expand the indemnification obligations or limitations set forth onSchedule 11.2(a)(vi) or require the Company or its Affiliates to disclose any information the disclosure of which would result in the loss of Company’s attorney client privilege with respect to such information (provided,however, that Company shall develop an alternative to providing such information so as to address such matters that is reasonably acceptable to Company and Buyer).

ARTICLE VI

PRE-CLOSING COVENANTSOF BUYER

6.1Required Approvals.

(a) As promptly as practicable after the date hereof, Buyer shall, and shall cause its Affiliates (including the Investor and its “ultimate parent entity”) to, use its commercially reasonable efforts to make all notices and filings in connection with the consents, approvals, waivers and authorizations required by any Legal Requirement to be made by it (or them) in order to consummate the transaction contemplated hereby. From the date of this Agreement until the Closing, Buyer shall, to the extent required by the HSR Act to, file within ten (10) days after the date hereof with the United States Federal Trade Commission and the United States Department of Justice the notification and report form required for the transactions contemplated hereby (which shall request “early termination” of the applicable waiting period) and any supplemental or additional information which may be requested in connection therewith pursuant to the HSR Act and will comply in all material respects with the requirements of the HSR Act. Buyer shall promptly deliver to the Companies copies of all filings, correspondence and Orders to and from any Governmental Authority in connection with the transactions contemplated hereby.

(b) Without limiting the generality of the undertakings of Buyer pursuant to Section 6.1(a), Buyer shall, and shall cause its Affiliates (including the Investor and its “ultimate parent entity”) to use its commercially reasonable efforts to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable. Buyer agrees not to extend, directly or indirectly, any waiting period under the HSR Act or enter into any agreement with a Governmental Authority to delay or not to consummate the transactions contemplated by this Agreement except with the prior written consent of Company. Buyer will (x) promptly notify Company of any written communications to Buyer from any Governmental Authority and, subject to applicable Legal Requirements, if practicable, permit Company to review in advance any proposed written communication (other than any portions thereof that contain confidential or proprietary information of or relating to Buyer or its Affiliates or individuals associated with Buyer or its Affiliates) to any such Governmental Authority and incorporate Company’s reasonable comments, (y) not agree to participate in any substantive meeting or discussion with any such Governmental Authority in respect of any filing, investigation or inquiry concerning this Agreement and the transactions contemplated hereby unless it consults with Company in advance and, to the extent permitted by such Governmental Authority, gives Company the opportunity to attend (other than with respect to any portions of such meeting that are in respect of confidential or proprietary information of or relating to Buyer or its Affiliates or individuals associated with Buyer or its Affiliates), and (z) furnish Company with copies of all correspondence, filings and written communications (other than any portions thereof that contain confidential or proprietary information of or relating to Buyer or its Affiliates or individuals associated with Buyer or its Affiliates) between Buyer and its Representatives on one hand, and any such Governmental Authority or its staff on the other hand, with respect to the transactions contemplated by this Agreement. If any

administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging as violative of any applicable Legal Requirements, or if any statute, rule, regulation, executive order, decree, injunction or administrative order is enacted, entered, promulgated or enforced by a Governmental Authority that would make the transactions contemplated by this Agreement illegal or would otherwise prohibit or materially impair or delay the consummation of the transactions contemplated by this Agreement, Buyer shall use its commercially reasonable efforts to contest and resist any such action or proceeding and shall use its commercially reasonable efforts to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by Agreement and to have such statute, rule, regulation, executive order, decree, injunction or administrative order repealed, rescinded or made inapplicable so as to permit consummation of the transactions contemplated by this Agreement.

(c) Notwithstanding the foregoing or any other provision in this Agreement to the contrary, nothing herein shall require, or be deemed to require, (i) Buyer or the Company (or any of their respective Subsidiaries or Affiliates) to take any action, or propose or accept (or commit to propose or accept) any undertaking, condition, restriction, obligation or requirement with respect to Buyer, the Company, their respective Subsidiaries or Affiliates or their or their respective Subsidiaries’ or Affiliates’ assets if such action, undertaking, condition, restriction, obligation or requirement, individually or in the aggregate, (A) would reasonably be expected to require Buyer, the Company or their respective Subsidiaries or Affiliates to sell, license, transfer, assign, lease, dispose of or hold separate any business or assets, (B) would reasonably be expected to result in any limitations on Buyer, the Company or their respective Subsidiaries or Affiliates to own, retain, control, conduct or operate all or a portion of their respective businesses or assets or (C) would reasonably be expected to deprive Buyer, its Subsidiaries or Affiliates of a benefit or benefits (after taking into account the adverse effect on Buyer, its Subsidiaries and its Affiliates (including the Company and its Subsidiaries) of the action or actions proposed to be taken) of the transactions contemplated by this Agreement or (ii) Buyer, Intermediate Holdings, or Merger Sub to provide to any Person (other than as required by the HSR Act in connection with the filing of the notification and report form required for the transactions contemplated hereby with the United States Federal Trade Commission and the United States Department of Justice) any confidential or privileged information in respect of (x) the Investor, (y) Persons controlling Buyer, Intermediate Holdings or Merger Sub, or (z) any Affiliates of Buyer, Intermediate Holdings or Merger Sub, other than in the case of clauses (y) and (z), Buyer, Intermediate Holdings and Merger Sub.

6.2Non-Disclosure Obligations. The terms of the Non-Disclosure Agreement relating to obligations with respect to confidential information and nonsolicitation are hereby incorporated by reference and such terms shall continue in full force and effect until the earlier of the Closing and the date that such Non-Disclosure Agreement is terminated pursuant to its terms. The Parties hereto acknowledge that the confidentiality provisions of the Non-Disclosure Agreement shall cover all information provided by the Company Entities or their Representatives to Buyer, Merger Sub or any of their Representatives or Affiliates in connection with or pursuant to the terms of this Agreement. Except as set forth in the first sentence of this Section 6.2, the Non-Disclosure Agreement shall remain in full force and effect in accordance with their terms.

6.3Financing. Each of Buyer, Intermediate Holdings and Merger Sub shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the proceeds of the Debt Financing concurrently with the Closing on terms and conditions described in the Debt Commitment Letter (including using reasonable best efforts to (i) obtain any necessary rating agency ratings, (ii) maintain in effect the Commitments (at no additional cost or expense to, and with no adverse effect on, Buyer, Intermediate Holdings or Merger Sub), (iii) satisfy on a timely basis all conditions applicable to

Buyer, Intermediate Holdings and Merger Sub to obtain the Debt Financing (including by consummating the financing contemplated by the Equity Commitment Letter) that are within their control and comply with the obligations thereunder, (iv) negotiate definitive agreements with respect to the Debt Commitment Letter on terms and conditions contained therein (including any “flex” provisions) or on terms no less favorable to Intermediate Holdings (unless otherwise agreed by Intermediate Holdings in its sole discretion) (the “Definitive Financing Agreements”) and upon the execution thereof, deliver a copy to the Company, (v) seek to enforce its rights under the Debt Commitment Letter and the Definitive Financing Agreements in the event of a breach by the Financing Parties that materially impedes or materially delays the Closing, including by seeking specific performance against the parties thereto, and (vi) with respect to any replacement commitments, satisfy on a timely basis all conditions applicable to Intermediate Holdings and Merger Sub in such definitive agreements that are within their control. Buyer and Intermediate Holdings shall keep Company reasonably informed of material developments in respect of the financing contemplated by the Commitments to which it is a party in accordance with this Section 6.3. In furtherance of the provisions of this Section 6.3, the Debt Commitment Letter may be amended or superseded without the prior consent of Company to replace or add one or more lenders, lead arrangers, bookrunners, syndication agents or similar entities which had not executed the Debt Commitment Letter as of the date hereof, or otherwise,provided, that in no event shall the Debt Commitment Letter be amended or superseded in a manner that would (i) expand in any way that is adverse to the Company the conditions to the Debt Financing set forth in the Debt Commitment Letter; (ii) reasonably be expected to prevent or materially delay the Closing; or (iii) reduce the aggregate amount of Debt Financing set forth in the Debt Commitment Letter (unless, in the case of this clause (iii), replaced with an amount of new equity financing on terms no less favorable to Buyer than the terms set forth in the Equity Commitment Letter). In the event that all conditions to the Commitments (other than in connection with the Debt Commitment Letter, the availability or funding pursuant to the Equity Commitment Letter) have been satisfied, each of Buyer and Intermediate Holdings shall use its reasonable best efforts to cause the lenders and other persons providing the Commitments to fund the financing required to consummate the Merger on the Closing Date (including by seeking specific performance to cause such lenders and other persons to fund such financing) if all conditions to closing contained in Article VII are satisfied or waived (other than those conditions that (A) by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions and (B) are not satisfied solely as a result of a breach by Buyer, Intermediate Holdings or Merger Sub of their respective obligations under this Agreement). Buyer and Intermediate Holdings shall give Company prompt notice of any material breach by any party of the Commitments to which it is a party, any termination of any of the Commitments to which it is a party, and any condition to the Commitments to which it is a party not likely to be satisfied, in each case, to the extent it becomes aware of such material breach, termination or condition. If any portion of the Debt Financing becomes unavailable on the terms and conditions (including the flex provisions) set forth in the Debt Commitment Letter, Buyer and Intermediate Holdings shall use its reasonable best efforts to arrange alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated by this Agreement on terms and conditions no less favorable to Intermediate Holdings or Merger Sub (as determined in the reasonable judgment of Intermediate Holdings) than those set forth in the Debt Commitment Letter (including the flex provisions) as promptly as practicable following the occurrence of such event, but in no event later than the last day of the Marketing Period. For the avoidance of doubt, the obtaining of the financing provided for by the Commitments, or any alternative financing, is not a condition to Closing. Notwithstanding anything herein to the contrary, in no event shall Buyer, Intermediate Holdings or any Affiliate thereof be required to provide any additional equity financing in excess of the amount expressly set forth in the Equity Commitment Letter. Notwithstanding anything herein to the contrary, in no event shall Buyer, Intermediate Holdings or Merger Sub be required pursuant to this Agreement to agree to pay to the lenders, and the other Persons providing the financing set forth in the Debt Commitment Letter, any additional fees or to increase any interest rates applicable to the Debt Commitment Letter (other than pursuant to the “flex” provisions therein, if any) or agree to enter into any financial or other material covenants or agreements on terms not otherwise expressly set forth in

the Debt Commitment Letter. For purposes of this Agreement, unless otherwise agreed among the parties hereto, the “Marketing Period” shall mean the first period of twenty (20) consecutive Business Days after the date hereof (A) throughout and on the last day of which (i) Intermediate Holdings shall have the Required Information that Company is required to provide to Intermediate Holdings pursuant to Section 5.7 and such information shall remain compliant at all times with applicable provisions of Regulation S-X and Regulation S-K under the Securities Act and (ii) nothing has occurred and no condition exists that would cause any of the conditions set forth in Sections 7.1 and 7.2 (other than the receipt of the certificates referred to therein) to fail to be satisfied assuming the Closing were to be scheduled for any time during such 20 consecutive Business Day period and (B) throughout and on the last day of which the conditions set forth in Section 7.3 through 7.6 (excluding conditions that, by their nature, cannot be satisfied until the Closing) shall be satisfied;provided, that the “Marketing Period” shall not be deemed to have commenced if, prior to the completion of the Marketing Period, Grant Thornton LLP shall have withdrawn its audit opinion with respect to any financial statements contained in the Audited Financial Statements.

6.4Reasonable Commercial Efforts. Subject to the terms and conditions of this Agreement, from the date of this Agreement until the Closing, Buyer shall, and shall cause Intermediate Holdings and Merger Sub to, (i) take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable Legal Requirements to consummate the transactions contemplated hereby as soon as reasonably practicable, (ii) use its commercially reasonable efforts to deliver or cause to be delivered at the Closing the items to be delivered by Buyer, Intermediate Holdings and Merger Sub, as the case may be, at or prior to the Closing, and (ii) not take any action that will have the effect of unreasonably delaying, impairing or impeding, in any material respect, the receipt of any authorizations, consents, orders or approvals to be sought pursuant to Section 6.1;provided, that in no event shall Buyer, Intermediate Holdings or any Affiliate thereof be required to provide any additional equity financing in excess of the amount expressly set forth in the Equity Commitment Letter.

Buyer shall prepare such Tax Returns consistent with past practices of Company, including claiming amortization and depreciation deductions to the greatest extent possible under applicable Tax law (unless otherwise required by applicable law or clause (A) through (F) above of this Section 9.4(a)) and shall provide the Sellers’ Representative the right to review and comment on such Tax Returns no later than thirty (30) days prior to the due date for filing such Tax Returns, such comments to be delivered to Buyer by Sellers’ Representative within the next fifteen (15) days following Sellers’ Representative’s receipt of such Tax Returns. Buyer and Sellers agree that Buyer or Company, as applicable and consistent with the foregoing provisions of this Section 9.4(a), shall deduct all Compensation Transaction Deductions for U.S. and state Tax purposes. Additionally, with respect to any items other than the Compensation Transaction Deductions or Other Transaction Deductions (which shall be dealt with as provided by Section 9.4(i)) and without limiting the arbitration provisions contained in this Section 9.4(a), Buyer shall, in good faith, take into account and reflect on such Tax Returns any reasonable comments (including proposed positions, elections, and the treatment of a particular item of income or expense) proposed by Sellers’ Representative,provided that, subject to the provisions of this Section 9.4, Buyer has ultimate control of such Tax Returns. In the event the parties are unable to resolve any dispute with respect to the items set forth in the Seller’s Representative’s comments (the “Disputed Tax Items”) within thirty (30) days after Buyer has received Sellers’ Representative’s written request for changes, Buyer and the Sellers’ Representative shall within ten (10) days thereafter submit the remaining Disputed Tax Items for resolution to the Independent Accounting Firm. The Independent Accounting Firm shall determine the proper treatment of the Disputed Tax Items in accordance with applicable Tax law and this Section 9.4 and the applicable Tax Returns shall be revised to reflect such determination. The Independent Accounting Firm shall be instructed by Buyer and the Sellers’ Representative to determine and report to Buyer and the Sellers’ Representative upon the resolution of such remaining Disputed Tax Items within thirty (30) days after such submission but in any event no later than ten (10) days prior to the due date for the applicable Tax Return. Each of the Buyer and Sellers’ Representative will be afforded the opportunity to present to the Independent Accounting Firm any material such party deems relevant to the Independent Accounting Firm’s determination. Buyer and Sellers’ Representative shall each furnish to the Independent Accounting Firm such work papers and other documents and information relating to the

remaining Disputed Tax Items as the Independent Accounting Firm may request. Notwithstanding anything herein to the contrary, with respect to its determination of each Disputed Tax Item, the Independent Accounting Firm may only decide in favor of the position presented by either Buyer or Sellers’ Representative, and may not make a determination other than in favor of one of the two positions presented with respect to each such Disputed Tax Item and, accordingly, shall determine which position is more likely to prevail under applicable Tax law. The fees and disbursements of the Independent Accounting Firm shall be allocated between Buyer and the Sellers’ Representative, in the same proportion that the aggregate amount of such remaining Disputed Tax Items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by each such Party (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining Disputed Tax Items so submitted.

(b)Amended Tax Returns. If the filing of any amended Tax Return could reduce amounts to which the Sellers are entitled to receive hereunder or result in an indemnification obligation of Sellers under this Agreement, neither Buyer, Merger Sub, the Surviving Corporation, the Subsidiaries or, to the extent within Buyer’s control, the other Company Entities shall amend any Tax Returns of Company or any of the other Company Entities for any Pre-Closing Tax Period without the prior written consent of the Sellers’ Representative, which consent shall not be unreasonably conditioned, delayed or withheld.

(c)Closing Date Course of Business Indemnity. The indemnity obligations of the Sellers under Section 11.2(a) (including under Section 11.2(a)(iv)) shall not cover Tax liabilities resulting from any transaction of Buyer or any of its Affiliates not in the ordinary course of business (other than the transactions contemplated hereunder) that occurs on the Closing Date but after the Closing and Buyer or any of its Affiliates shall not enter into any such transactions to the extent they would reduce the amounts potentially payable to the Sellers pursuant to this Section 9.4.

(d)End of Tax Year. Buyer, Merger Sub, Surviving Corporation and, to the extent within Buyer’s control, the other Company Entities shall not take any action, or permit any action to be taken, that may prevent the tax year of Company and the other Company Entities from ending for federal and applicable state, local and foreign income tax purposes at the end of the day on the Closing Date. Buyer, Merger Sub and Surviving Corporation will file consolidated U.S. federal income tax returns for all taxable periods after the Closing Date which may include items of expense that would constitute Compensation Transaction Deductions or Other Transaction Deductions, to the extent permitted by applicable law.

(e)Filing Dates of Tax Returns. Without limiting the general provisions of Section 9.4(a) (including the review, comment and dispute resolution provisions), Buyer shall cause the Surviving Corporation to prepare and file income Tax Returns for each Tax period ending on the Closing Date no later than one hundred twenty (120) days following the Closing Date. In the case of any Tax Return for a Pre-Closing Tax Period that does not end on the Closing Date (a “Straddle Period”), and for purposes of determining hereunder the amount of Taxes attributable to a Pre-Closing Tax Period or a Post-Closing Tax Period generally, the amount of Taxes attributable to the Pre-Closing Tax Period shall be deemed to be (i) in the case of Taxes imposed on a periodic basis (such as certain franchise Taxes, real or personal property Taxes), the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period) multiplied by a fraction, the numerator of which is the number of calendar days in the Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire relevant Straddle Period and (ii) in the case of Taxes not described in (i) above (such as Taxes that are based upon or related to income or receipts, based upon occupancy or imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible)), the amount of any such Taxes shall be determined as if such taxable period and the taxable period of all Company Entities ended of as of the close of business on the Closing Date.

(f)Cooperation on Tax Matters. Buyer, Merger Sub, the Surviving Corporation, the Company Entities (to the extent within Buyer’s control) and the Sellers’ Representative shall cooperate fully, as and to the extent reasonably requested by the other parties, in connection with the filing of Tax Returns (including any amended Tax Return) for a period prior to (or including) the Closing Date (which amended Tax Return may only be filed pursuant to Section 9.4(b) or 9.4(g)), any Tax audits, Tax proceedings or other Tax-related claims, and allowing the Sellers’ Representative to review Tax Returns to determine or verify the proper amounts payable as Tax Refund Consideration or as Tax Savings Consideration hereunder, and any mechanisms or payment processes reasonably requested by the Sellers’ Representative to pay Tax Refund Consideration or Tax Savings Consideration to the Sellers as provided herein. Such cooperation shall include, upon the Sellers’ Representative’s request, providing records and information that are reasonably relevant to any such matters, making employees available on a mutually convenient basis to provide additional information, and explaining any materials provided pursuant to this Section 9.4. Buyer, Merger Sub, the Surviving Corporation and the Company Entities shall not destroy or dispose of any Tax workpapers, schedules or other materials and documents supporting Tax Returns of Company, the Subsidiaries and, to the extent within Buyer’s control, the other Company Entities for Pre-Closing Tax Periods until the tenth anniversary of the Closing Date, without the prior written consent of the Sellers’ Representative, and before any disposition or destruction of such materials at any time, Buyer shall give thirty (30) days prior written notice of any such proposed disposition or destruction to the Sellers’ Representative, and the Sellers’ Representative shall have the right, in its sole discretion, to take possession of such materials and documents.

(g)Tax Refunds. The Sellers shall be entitled to receive from Buyer, Merger Sub, Surviving Corporation or the Subsidiaries all refunds (or credits for overpayments) of income Taxes from a Pre-Closing Tax Period, including any interest thereon (net of any Tax on such interest);provided,however, Sellers shall not be entitled to receive any refunds (or credits for overpayments) (i) of income Taxes resulting from an adjustment to income Taxes from a Pre-Closing Tax Period after the Survival Date (other than an adjustment arising as a result of claiming a refund with respect to any Compensation Transaction Deduction or Other Transaction Deduction, or any net operating or other loss with respect to a Pre-Closing Tax Period (e.g., not including any adjustments arising out of an audit or other proceeding with respect to Taxes that are made after the expiration of the Survival Date)) or (ii) that result from a Buyer Transaction Cost. Subject to Section 9.4(i) with respect to Tax refunds attributable to Other Transaction Deductions, promptly upon receipt of any income Tax refund (or credits for overpayment), and in no event later than ten (10) Business Days after receipt by Buyer, Merger Sub, the Surviving Corporation or any of the Subsidiaries, Buyer will, and will cause Merger Sub or the Surviving Corporation and/or the Subsidiaries to, deliver and pay over, by wire transfer of immediately available funds, such income Tax refunds (or credits for overpayments), including any interest thereon (net of any Tax on such interest) to the Sellers’ Representative, for payment to each of the Sellers in accordance with the provisions of Section 2.13(g). Notwithstanding the foregoing, the Sellers shall not be entitled to receive any refunds (or credits for overpayments) of Taxes resulting from the carryback of Tax attributes generated in a Post-Closing Tax Period except to the extent such Tax attributes result from Compensation Transaction Deductions or Other Transaction Deductions actually realized in a Post-Closing Tax Period (determined on a with and without basis). Buyer shall, as soon as is reasonably practicable, cause the Surviving Corporation or the Subsidiaries to file amended income Tax Returns or applications for income Tax refunds in order to obtain any income Tax refund (or credit for overpayment) that the Sellers are entitled to pursuant to this Section 9.4(g), and Buyer, Merger Sub, the Surviving Corporation and, to the extent within Buyer’s control, the Company Entities shall execute all other documents, take reasonable additional actions and otherwise reasonably cooperate as may be necessary for Buyer, Merger Sub, the Surviving Corporation and the Company Entities to obtain the income Tax refunds contemplated by this

Section 9.4(g). In addition, Buyer shall cause the Surviving Corporation to prepare and file IRS Form 1139 in respect of Company’s two taxable periods preceding Company’s tax period ending on the Closing Date no later than thirty (30) days after Company’s U.S. federal income Tax return for Company’s Tax year ending on the Closing Date is filed.

(h)Post-Closing Period Tax Payment. To the extent actually realized by Buyer, Merger Sub, Surviving Corporation, Company or any Subsidiaries, Buyer shall, subject to Section 9.4(i) with respect to Actual Tax Savings attributable to Other Transaction Deductions subject to a Tax Opinion Indemnification, pay to the Sellers’ Representative, by wire transfer of immediately available funds, an amount, in cash, equal to the Actual Tax Savings within ten (10) days of actually realizing such amount, and the Sellers’ Representative shall distribute such amount to each of Sellers in accordance with the provisions of Section 2.13(g). For purposes of this Agreement, “Actual Tax Savings” shall mean the excess of (A) the income Taxes that would have been incurred by Buyer and all the members of its affiliated group within the meaning of Section 1504(a)(1) of the IRC (without taking into account the exceptions under Section 1504(b) of the IRC) in each Post-Closing Tax Period calculated without taking into account both (1) any net operating losses of Company from Pre-Closing Tax Periods and (2) any Compensation Transaction Deductions and Other Transaction Deductions that are deductible in a Post-Closing Tax Period, over (B) the actual income Taxes incurred by Buyer and all the members of its affiliated group within the meaning of Section 1504(a)(1) of the IRC (without taking into account the exceptions under Section 1504(b) of the IRC) in any such Post-Closing Tax Period. For each Post-Closing Tax Period, Buyer will provide to Sellers’ Representative, within thirty (30) days of filing the Tax Return for such period with its calculations of the amount of the Actual Tax Savings, if any. For purposes of this Agreement, “Post-Closing Tax Period” shall mean any taxable period (or portion thereof) that is not a Pre-Closing Tax Period. For the avoidance of doubt, Buyer Transaction Costs shall not be treated as part of any net operating losses of Company from a Pre-Closing Tax Period for purposes of clause (A)(1) of the definition of Actual Tax Savings.

(i)Other Transaction Deductions. The Company shall deduct the Other Transaction Deductions to the extent Sellers’ Representative delivers (and shall not be required to deduct such amounts to the extent the Sellers’ Representative does not deliver) an opinion of the Independent Accounting Firm or, if the Independent Accounting Firm is not a Big Four Accounting Firm, an independent Big Four Accounting Firm mutually agreed upon by Buyer and the Sellers’ Representative (the Independent Accounting Firm or such other firm, the “Tax Opinion Accounting Firm”) that such position is at least “more likely than not” to prevail if challenged by the IRS, which deductions shall be taken consistent with the provisions of Section 9.4(a)(E) and (F);provided,however, if the Sellers’ Representative delivers an opinion other than an unqualified “will” level opinion, the Buyer shall be entitled to receive indemnification with respect to any Losses in respect of such position not prevailing, which indemnification obligation (the “Tax Opinion Indemnification”) shall survive until thirty (30) days after the expiration of the applicable statute of limitations (the “Tax Opinion Indemnification Expiration Date”). Any such indemnification shall be limited to the Indemnification Escrow Amount held pursuant to the Escrow Agreement (including any additional amounts placed in escrow and held pursuant to the Escrow Agreement pursuant to this Section 9.4(i)). For the avoidance of doubt, to the extent the Sellers’ Representative delivers an unqualified “will” opinion from the Tax Opinion Accounting Firm with respect to all or any part of the Other Transaction Deductions, the Sellers’ Representative shall not be required to provide the Tax Opinion Indemnification with respect to Losses attributable to the deductions covered by such opinion. Any income Tax refunds (or credits for overpayments) or Actual Tax Savings attributable to any Other Transaction Deductions shall be determined on a with and without basis (i.e., as if the Other Transaction Deductions were the last deductions to be taken). With respect to any Other Transaction Deductions subject to the Tax Opinion Indemnification, (i) if and to the extent on or prior to the Survival Date, any Tax refund (or credit for overpayment) or reduction in taxable income is actually received or realized with respect to such deductions or such deductions result in Actual Tax Savings that

are payable to the Sellers’ Representative then (x) if all or any portion of the Indemnification Escrow Amount has been used to satisfy Indemnification Claims or has otherwise been reduced pursuant to the Escrow Agreement, a portion of any such Tax refund (or credit for overpayment) or Actual Tax Savings equal to the amount of the Indemnification Escrow Amount used to satisfy Indemnification Claims or otherwise reduced pursuant to the Escrow Agreement (but not in excess of the amount of such Tax refund or Actual Tax Savings) shall be delivered by the Company to the Escrow Agent to be held until the applicable Tax Opinion Indemnification Expiration Date (or such later date required under the Escrow Agreement) in accordance with this Agreement and the Escrow Agreement and the balance shall be paid to Sellers’ Representative in accordance with this Agreement and (y) on the Survival Date, an amount equal to 45% of the amount of such Other Transaction Deductions that resulted in such Tax refund (or credit for overpayment), reduction in taxable income or Actual Tax Savings shall be retained by the Escrow Agent and held pursuant to the Escrow Agreement and this Agreement until the applicable Tax Opinion Indemnification Expiration Date (or such later date required under the Escrow Agreement), and (ii) if and to the extent on or prior to the Survival Date such Other Transaction Deductions have not resulted in a Tax refund (or credit for overpayment), reduction in taxable income or Actual Tax Savings that has been actually received or realized then (x) any Tax refund (or credit for overpayment) or Actual Tax Savings with respect to such Other Transaction Deductions that is otherwise payable to the Sellers’ Representative shall be delivered to the Escrow Agent to be held until the applicable Tax Opinion Indemnification Expiration Date (or such later date required under the Escrow Agreement) in accordance with this Agreement and the Escrow Agreement and (y) on the Survival Date, an amount equal to 5% multiplied by the amount of such Other Transaction Deductions shall be retained by the Escrow Agent and held pursuant to the Escrow Agreement and this Agreement until the applicable Tax Opinion Indemnification Expiration Date (or such later date required under the Escrow Agreement). To the extent the Escrow Agreement requires any consent, notice or other action of Buyer and/or Sellers’ Representative to effectuate the provisions of this Section 9.4(i), Buyer and/or Sellers’ Representative, as applicable, shall promptly deliver such required consent or notice or take such required action.

(j)No Section 338 Election. Neither Buyer, Merger Sub, Surviving Corporation nor any of their affiliates shall make an election under Section 338 of the IRC with respect to the purchase of Company Shares.

(k)Transfer Taxes. Any and all transfer, sales, use, excise, goods and services, health services, conveyance, recording or any other similar fees or taxes (including, without limitation, title recording or filing fees, mutation taxes and other amounts payable in respect of transfer filings), and all documentary or other stamp taxes, arising out of or related to the transactions contemplated by this Agreement shall be borne equally by the Sellers on the one hand, and Buyer on the other hand;provided, that any stamp or transfer taxes payable to the State of New York or New York City shall be paid by Buyer and Buyer shall be entitled to any rebates or refunds of such State of New York or New York City stamp or transfer taxes. The Parties shall consult with each other in good faith and shall cooperate fully with each other in planning for the reduction or elimination of any such taxes.

(l)Tax Elections and Positions. Buyer covenants and agree that neither it nor Company, nor any of their respective Subsidiaries shall retroactively apply any changes or alterations in the tax positions and elections taken by Company or any of the Subsidiaries on or prior to the Closing Date to any taxable periods prior to the Closing Date in any manner that would give rise to any obligations of Sellers under this Agreement (including Indemnification Claims under Section 11.2).

(m)Section 351 Treatment. The Buyer and the Rollover Stockholders agree to use their reasonable best efforts to treat the transactions contemplated hereby in accordance with IRC Section 351 and report the transaction in a manner consistent with such treatment.

(n)Additional Matters. The Parties agree and acknowledge that the right of an Optionholder to receive the payments contemplated by Section 2.10(d)(iv) with respect to such Person’s Options (other than Rollover Options) is substantially vested within the meaning of Treasury Regulation Section 1.83-6 and shall be treated as such regardless of whether the Optionholder delivers to Company a fully completed and executed Option Rollover Election; Cancellation and Payment Acknowledgement at or prior to the Closing. As a result, the Company shall deduct the amounts payable to the holders of Options (other than Rollover Options) on Company’s income Tax Returns for the taxable period ending on the Closing Date (to the extent such amounts would otherwise have been deductible in such period consistent with Section 9.4(a)) regardless of whether the holders thereof have completed an Option Rollover Election; Cancellation and Payment Acknowledgement.

9.5Directors’ & Officers’ Indemnification.

(a) For a period of six years after the Effective Time (and such additional period of time as may be necessary to fully and finally resolve any claims for indemnification which have been duly submitted prior to the six year anniversary of the Effective Time), unless otherwise required by applicable Legal Requirements, the Organizational Documents of the Surviving Corporation and the Subsidiaries shall contain provisions no less favorable in the aggregate with respect to the indemnification of and advancement of expenses to directors and officers than are set forth in the Organizational Documents of Company as in effect on the date hereof. The Surviving Corporation shall indemnify, and advance expenses to, each present and former director or officer of Company and each Subsidiary (collectively, the “D&O Indemnified Parties”), in and to the extent of their capacities as such and not as stockholders of Company, in respect of actions, omissions or events through the Effective Time to the to the fullest extent permitted by law. Without limiting the generality of the preceding sentence, if any D&O Indemnified Party becomes involved in any actual or threatened action, suit, claim, proceeding or investigation covered by this Section 9.5(a) after the Effective Time, the Surviving Corporation shall, to the fullest extent permitted by law, promptly advance to such D&O Indemnified Party his or her legal or other expenses (including the cost of any investigation and preparation incurred in connection therewith);provided, that any D&O Indemnified Party to whom expenses are advanced provides a written undertaking to repay such advanced expenses if it is ultimately determined that such D&O Indemnified Party is not entitled to indemnification.

(b) At or prior to the Closing Date, Company shall purchase and pay in full a “tail” prepaid insurance policy with respect to Company’s existing directors’ and officers’ liability insurance coverage for Company’s and the Subsidiaries’ directors and officers that shall provide such directors and officers with coverage for six (6) years following the Effective Time (including with respect to acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby). The cost of the premiums for such “tail” prepaid insurance policy shall be treated as a Company Transaction Expense to the extent it remains unpaid on the Closing Date. Buyer shall, and shall cause the Surviving Corporation to, maintain such policy in full force and effect.

(c) The obligations under this Section 9.5 shall not be terminated or modified in such a manner as to adversely affect any D&O Indemnified Party to whom this Section 9.5 applies without the consent of such D&O Indemnified Party (it being expressly agreed that the D&O Indemnified Parties to whom this Section 9.5 applies shall be third party beneficiaries of this Section 9.5 and shall be entitled to enforce the covenants contained herein). The obligations under this Section 9.5 shall be in addition to any other contractual or other rights of indemnification for the benefit of any D&O Indemnified Parties.

(c) by written notice from Buyer following a breach of any covenant or agreement of Company contained in this Agreement, or if any representation or warranty of Company contained in this Agreement shall be or shall have become inaccurate, in either case such that any of the conditions set forth in Sections 7.1 and 7.2 would not be satisfied as of the time of such breach or as of the time of such representation or warranty was or shall have become inaccurate and such breach or inaccuracy shall not have been cured within thirty (30) days after written notice of such breach from Buyer is received by Company;provided, that the right to terminate this Agreement pursuant to this Section 10.1(c) shall not be available to Buyer if it is then in breach of any representations, warranties, covenants or agreements contained in this Agreement that would result in any of the conditions set forth in Section 8.1 or 8.2 not being satisfied;

and willing to consummate the transactions contemplated by this Agreement during such period;provided, that during such period of two (2) Business Days following the date the Closing should have occurred pursuant to Section 2.12, no party shall be entitled to terminate this Agreement pursuant to Section 10.1.

10.2Effect of Termination.

(a) If this Agreement is terminated in accordance with Section 10.1, this Agreement shall become null and void and of no effect with no liability to any Person on the part of any Party hereto (or any of its Representatives or Affiliates) and all further obligations of the Parties under this Agreement shall terminate, except for Section 6.2, this Article X and Article XII;provided,however, that except as otherwise provided herein and subject to Sections 10.2(b) and 10.2(c), the liability of any Party for any breach by such Party of the representations, warranties, covenants or agreements of such Party set forth in this Agreement occurring prior to the termination of this Agreement shall survive the termination of this Agreement and, in addition, in the event of any termination of this Agreement and a related action for breach of contract, the prevailing Party shall be reimbursed by the other Parties to the action for reasonable attorneys’ fees and expenses relating to such action, and in no event shall any Party be liable for punitive damages.

(b) Notwithstanding the foregoing, in the event this Agreement is terminated by Company pursuant to Section 10.1(d) or Section 10.1(e), then Buyer shall within three (3) Business Days of such termination make a payment in cash to Company in an amount equal to $15,000,000 (the “Buyer Fee”). The Parties acknowledge and agree that in the event this Agreement is terminated by Company pursuant to Section 10.1(d) or Section 10.1(e) Buyer shall not be responsible for paying Company or its Affiliates any amounts in excess of an amount equal to the Buyer Fee (and the expenses, if any, contemplated by the second sentence in Section 10.2(c)).

(c) The parties acknowledge that the agreements contained in this Section 10.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the parties would not enter into this Agreement. Accordingly, if Buyer fails to promptly pay the amount due pursuant to Section 10.2(b) and, in order to obtain such payment, Company commences a suit that results in a judgment against Buyer for the amount set forth in Section 10.2 or any portion thereof, Buyer, Intermediate Holdings or Merger Sub shall pay to Company (i) its documented out-of-pocket costs and expenses (including reasonable attorneys’ fees) in connection with such suit and (ii) interest on such amount or portion thereof at the prime rate of Bank of America N.A. in effect on the date such payment was required to be made through the date of payment, which aggregate amount pursuant to the foregoing clauses (i) and (ii), and, for the avoidance of doubt, Section 10.2(a), shall not be greater than $2,000,000. Notwithstanding anything to the contrary in this Agreement, (i) Company’s receipt of the Buyer Fee (and the expenses, if any, contemplated by the previous sentence) from Buyer pursuant to Section 10.2(b) (or from the Investor pursuant to the Limited Guarantee), or any settlement (with the consent of Company and the Sellers’ Representative) thereof, shall be the sole and exclusive remedy of Company and its Affiliates against Buyer, Intermediate Holdings, Merger Sub, the Investor, the former, current and future equity holders, controlling persons, directors, officers, employees, agents, Affiliates, members, managers, general or limited partners or assignees of Buyer, Intermediate Holdings, Merger Sub, the Investor or the Financing Parties or any former, current or future stockholder, controlling person, director, officer, employee, general or limited partner, member, manager, Affiliate, agent or assignee of any of the foregoing (each a “Related Person” and collectively, the “Related Persons”) for any loss suffered in connection with this Agreement (except in the case of an order of specific performance as and only to the extent expressly permitted by Section 12.10(b), in which case the Buyer Fee shall not be payable if the Closing occurs), (ii) in the event the Closing does not occur, in no event shall Buyer, Intermediate Holdings, Merger Sub, the Financing Parties or any Related Person thereof be subject to (nor shall

Company or any of its Affiliates seek to recover) monetary damages in excess of the amount of the Buyer Fee (inclusive of any amounts owing under the Limited Guarantee) and the expenses, if any, contemplated by the previous sentence for all losses suffered in connection with this Agreement, or arising from, relating to, or as a result of, any breach of any representation, warranty, covenant or agreement by Buyer or arising from any claim or cause of action Company or any of its Affiliates may have (including for a breach of Article II hereof as a result of the Debt Financing not being available to be drawn down or otherwise arising from the Debt Commitment Letter) or the failure of the Merger to be consummated and (iii) in no event shall Company or any of its Affiliates seek to recover monetary damages from any of Intermediate Holdings, Merger Sub, the Financing Parties or any Related Person thereof (other than Buyer), or any of its representatives (other than as provided in the Limited Guarantee). In no event shall the Company be entitled to seek the remedy of specific performance of this Agreement other than solely under the specific circumstances and as specifically set forth in Section 12.10(b). For the avoidance of doubt, under no circumstances (1) will Company be entitled to monetary damages in excess of the amount of the Buyer Fee plus the amount of expenses, if any, contemplated by the second sentence of this Section 10.2(c) and, (2) shall Company be permitted or entitled to receive both a grant of specific performance and any money damages, including all or any portion of the Buyer Fee (and/or the amount of the expenses, if any, contemplated by the second sentence of this Section 10.2(c)).

The representations, warranties, covenants and agreements of the Parties contained in this Agreement shall survive the Closing, regardless of any investigation made by or on behalf of any Party, and shall expire on the Survival Date;provided, that all covenants and agreements of the Parties set forth in this Agreement to be performed after the Closing (including the Tax Opinion Indemnification) (collectively, the “Post-Closing Obligations”) shall survive the Closing and remain in full force and effect indefinitely, unless otherwise terminated by their express terms;provided, that if an Indemnitee delivers an Indemnification Notice to an Indemnitor before the Survival Date or the applicable Tax Opinion Indemnification Expiration Date, then the applicable representation, warranty, covenant and agreement shall survive until, but only for purposes of, the resolution of the matter covered by such Indemnification Notice.

11.2Indemnification by Sellers.

(a) Subject to the terms and conditions of this Article XI and except as set forth onSchedule 11.2, from and after the Effective Time, Sellers shall indemnify, defend and hold harmless, solely out of the Indemnification Escrow Amount, Buyer and Buyer’s Affiliates (including without limitation the Company Entities after the Closing), directors, officers, employees, agents, and stockholders and successors and assigns (collectively, “Buyer Indemnitees”) from any and all Losses incurred by such Persons arising out of or relating to or resulting from: (i) any inaccuracy or breach of any representation or warranty of Company contained in this Agreement or any certificate delivered by or on behalf of Company pursuant to Sections 7.1 and 7.2 (A) on and as of the date of this Agreement with the same effect as though made on and as of the date of this Agreement (other than any such representation or warranty that speaks as of a specific date or time other than the date of this Agreement), (B) on and as of the Closing Date with the same effect as though made on and as of the Closing Date (other than any such representation or warranty that speaks as of a specific date or time other than the date of this Agreement or the Closing Date), or (C) on and as of the date or time when made, in the case of any representation or warranty that speaks as of a specific date or time other than the date of this Agreement or the Closing Date, (ii) any breach by Company of any covenant or agreement to be performed by it (or any other Company Entity) pursuant to this Agreement, other than Post-Closing Obligations, (iii) any breach by Sellers and/or the Sellers’ Representative after the Closing, of any of their respective

(b) From and after the Closing, the rights of Buyer Indemnitees to indemnification under this Article XI shall constitute the sole and exclusive remedy of Buyer Indemnitees for any breach by any of the Company Entities of any provision of this Agreement, and no claim may be asserted nor any action commenced against Company under Section 11.2(a) unless an Indemnification Notice has been delivered to the Sellers’ Representative by Buyer (on behalf of Buyer Indemnitees) on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or action is based ceases to survive as set forth in Section 11.1, regardless of whether the subject matter of such claim or action shall have occurred before such date;provided,however, that Buyer Indemnitees may pursue specific performance and other equitable remedies for any matter that is indemnifiable under Section 11.2(a)(iii).

(c) Subject to the limitations contained herein, any Losses incurred as a result of any matter for which indemnification is required under this Section 11.2 shall be limited to the Indemnification Escrow Amount then remaining in the Escrow Account and not previously distributed pursuant to the terms of the Escrow Agreement and no indemnification pursuant to Section 11.2 shall be payable other than from the then remaining Indemnification Escrow Amount. From and after the Closing, the Indemnification Escrow Amount held pursuant to the Escrow Agreement shall constitute the sole and exclusive remedy and source of payment for all Buyer Indemnitees’ Losses and claims related to this Agreement, including any amounts payable by the Sellers’ Representative pursuant to Section 2.13, other than for fraud.

(d) Buyer shall not be entitled to indemnification under Section 11.2(a) in respect of the amount of any liabilities or assets of any of the Company Entities to the extent that the amount of such liabilities or assets are included and reflected with reasonable specificity in the calculation of the final Adjusted Net Working Capital as finally determined under the procedures set forth in Section 2.13 or are specifically excluded pursuant to clause (g) of the definition of Corporate Adjusted Current Liabilities

11.3Indemnification by Buyer.

(a) Subject to the terms and conditions of this Article XI, from and after the Effective Time, Buyer shall indemnify, defend and hold harmless the Sellers and their respective Affiliates (other than the Company Entities), directors, officers, employees, agents, and stockholders and successors and assigns (collectively, “Seller Indemnitees”) from any and all Losses incurred by such Persons arising out of or relating to or resulting from: (i) any inaccuracy or breach of any representation or warranty of Buyer contained in Article IV or any certificate delivered by or on behalf of Buyer pursuant to Sections 8.1 and 8.2 (A) on and as of the date of this Agreement with the same effect as though made on and as of the date of this Agreement (other than any such representation or warranty that speaks as of a specific date or time other than the date of this Agreement or the Closing Date), (B) on and as of the Closing Date with the same effect as though made on and as of the Closing Date (other than any such representation or warranty that speaks as of a specific date or time other than the date of this Agreement or the Closing Date) or (C) on and as of the date or time when made, in the case of any representation or warranty that speaks as of a specific date or time other than the date of this Agreement or the Closing Date, (ii) any breach by Buyer of the covenants and agreements to be performed by Buyer pursuant to this Agreement, other than Post-Closing Obligations and (iii) any breach by Buyer, after the Closing, of any of Buyer’s Post-Closing Obligations.

(b) Notwithstanding anything to the contrary contained in this Agreement the rights of Seller Indemnitees to indemnification under this Article XI shall constitute the only and exclusive remedy of Seller Indemnitees for any breach by Buyer of any provision of this Agreement and any breach of the Companies of any Post Closing Obligation, and (ii) no claim may be asserted nor any action commenced against Buyer for indemnification under Section 11.3(a) unless an Indemnification Notice has been delivered to Buyer by the Sellers’ Representative (on behalf of Seller Indemnitees) on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or action is based ceases to survive as set forth in Section 11.1, regardless of whether the subject matter of such claim or action shall have occurred before or after such date;provided,however, that the Sellers’ Representative on behalf of Seller Indemnitees may pursue specific performance and other equitable remedies for any matter that is indemnifiable under clause (iii) of Section 11.3(a).

11.4Limitations on Indemnification.

(a) Notwithstanding any other provision of this Agreement to the contrary:

(i) for purposes of Section 11.2(a), with respect to each representation or warranty contained in this Agreement that is Qualified, no such Qualification shall be permitted for the purpose of determining whether an inaccuracy or breach of such representation or warranty has occurred or the amount of any Loss that is the subject of indemnification hereunder, and all Losses shall be calculated without regard to any Qualification;

(ii) no individual claim (or series of related claims) by an Indemnitee may be asserted (and no Indemnitee shall be entitled to indemnification with respect to any such claim or series of related claims) with respect to Section 11.2(a)(i) (excluding any inaccuracy or breach of the representations and warranties set forth in Section 3.4(e)) unless the aggregate amount of Losses that would be payable with respect to such claim (or series of related claims) exceeds an amount equal to $50,000 (it being understood that any such individual claim (or series of related claims) for amounts less than $50,000 shall be ignored for purposes of determining whether the Threshold has been exceeded);

(iii) the right of any Indemnitee to indemnification pursuant to Sections 11.2(a)(i) (excluding any inaccuracy or breach of the representations and warranties set forth in Section 3.4(e)) shall not be effective until the aggregate dollar amount of all Losses that would otherwise be indemnifiable pursuant thereto exceeds $1,500,000 (the “Threshold Amount”) and then only to the extent such aggregate amount exceeds the Threshold Amount;

(iv) except as increased pursuant to Section 9.4(i) solely for purposes of any Tax Opinion Indemnification, the right of any Indemnitee to indemnification pursuant to Section 11.2(a) shall be limited to $27,500,000 in the aggregate and no indemnification pursuant to such provisions shall be payable thereafter;

(v) the right of any Seller Indemnitee to indemnification pursuant to this Agreement shall be limited to an aggregate amount equal to the Purchase Price and no indemnification pursuant to this Agreement shall be payable thereafter; and

(vi) Buyer Indemnities, on the one hand, and Seller Indemnitees on the other hand, shall only be entitled to recover the full amount of a Loss once with respect to any item giving rise to a Loss.

(b) For purposes of determining the amount of any and all Taxes for which the Buyer Indemnities are entitled to indemnification pursuant to Section 11.2(a)(iv), the Taxes imposed on any Company Entity (other than the Company, the Subsidiaries and the Cluster Subsidiary Holding Companies) that are attributable to any Pre-Closing Tax Period shall be limited to the applicable ARA Ownership Percentage of such Taxes.

(c) Any amounts deposited and held under the Escrow Agreement pursuant to Section 9.4(i) and any amounts retained in and held under the Escrow Agreement pursuant to Section 9.4(i) shall only be used to satisfy Losses attributable to any position subject to a Tax Opinion Indemnification.

11.5Notice of Potential Claims for Indemnification.

(a) An indemnified party (the “Indemnitee”) shall give the indemnifying party or parties (the “Indemnitor”) reasonably prompt written notice (an “Indemnification Notice”) of any claim for indemnification by the Indemnitor under this Article XI (an “Indemnification Claim”), including but not limited to any Third Party Claim. The Sellers’ Representative shall be deemed to be the Indemnitor for purposes of this Section 11.5 and Section 11.6. Each Indemnification Notice shall specify the basis on which indemnification is sought and, to the extent known or reasonably calculable, the Indemnitee’s good faith estimate of the amount of its Losses and, in the case of a Third Party Claim, contain (by attachment or otherwise) such other relevant information as such Indemnitee may have concerning such Third Party Claim. The Indemnitee shall provide written notice as soon as reasonably practicable to the Indemnitor of all material developments relating to the related Indemnification Claim and any material changes in Indemnitee’s good faith estimate of the amount of its Losses. The Indemnitee shall provide the Indemnitor with reasonable access, upon reasonable prior written notice and during normal business hours, in a manner so as not to unreasonably interfere in any material respect with the normal business operations, to its books and records, properties and personnel relating to the Indemnification Claim. The Indemnitee will not be entitled to indemnification for Losses of the Indemnitee to the extent that any delay in providing an Indemnification Notice actually prejudices the Indemnitor’s ability to defend a Third Party Claim.

(b) If the Indemnification Claim involves a Third Party Claim, the provisions set forth in Section 11.6 shall be applicable.

11.6Third Party Claims. The obligations and liabilities of the Parties hereunder with respect to a Third Party Claim for which an Indemnitee is entitled to indemnification pursuant to this Article XI shall be subject to the following terms and conditions:

(a) The Indemnitor shall have the right, but not the obligation, to defend against and to direct the defense of any such Third Party Claim and any related Proceeding, in its name or in the name of the Indemnitee at the Indemnitor’s expense and with counsel of the Indemnitor’s own choosing, which counsel shall be reasonably satisfactory to the Indemnitee, by providing written notice to the Indemnitee within fifteen (15) days following receipt of the Indemnification Notice;provided, that (i) the Indemnitee shall be entitled to direct the defense for only so long as the Indemnitor conducts the defense in an active and diligent manner, (ii) the Indemnification Claim is not in respect of any matter involving criminal liability and (iii) in the event the Third Party Claim is in respect of an Indemnification Claim by Buyer Indemnitees, the remaining Indemnification Escrow Amount exceeds the amount of the Third Party Claim and the amount of all other pending Indemnification Claims made by all Buyer Indemnitees, in each case, calculated based on the amount that could reasonably be expected to be paid with respect to such claims;provided,further, that the Indemnitee is hereby authorized (upon reasonable prior written notice to the

Indemnitor), and at the cost and expense of the Indemnitor, prior to the Indemnitor’s delivery of a written election to the Indemnitee of its agreement to defend any Third Party Claim, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnitor. If the Indemnitor elects to assume the defense of a Third Party Claim pursuant to, and in accordance with, the first sentence of this Section 11.6(a), the Indemnitee may participate in such defense with counsel of its own choosing, at its own expense. The Indemnitor shall not, as long as it actively and diligently conducts the defense of any Proceeding on behalf of the Indemnitee, be liable to the Indemnitee under this Article XI for any fees of other counsel or any other expenses with respect to the defense of such Proceeding incurred by the Indemnitee in connection with the defense of such Proceeding;provided,however, that notwithstanding the foregoing, the Indemnitor shall pay the reasonable attorneys’ fees of the Indemnitee if (x) the Indemnitee’s counsel shall have reasonably concluded and advised that there are defenses available to such Indemnitee that are different from or additional to those available to the Indemnitor, or (y) the Indemnitee’s counsel shall have advised the Indemnitee that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnitor and the Indemnitee. No settlement of, or payment in respect of, any Third Party Claim under this Article XI whereby the sole relief provided is monetary damages that are paid in full by the Indemnitor or from the remaining Indemnification Escrow Amount, as the case may be, shall be made by or on behalf of the Indemnitor without the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld or delayed). No settlement of, or payment in respect of, any Third Party Claim (i) where monetary damages are in excess of the remaining Indemnification Escrow Amount, (ii) that seeks non-monetary damages or other equitable remedies and/or (iii) that involves criminal liability, shall be made by or on behalf of the Indemnitor without the prior written consent of the Indemnitee.

(b) If, however, the Indemnitor fails or refuses to undertake the defense of such Third Party Claim within fifteen (15) days after the Indemnification Notice has been given to the Indemnitor by the Indemnitee, pursuant to, and in accordance with, the first sentence of Section 11.6(a), or if the Indemnitor later fails to conduct the defense in an active and diligent manner or withdraws from such defense, the Indemnitee shall have the right to undertake the defense of such claim with counsel of its own choosing, with Indemnitor responsible for the reasonable costs and expenses of such defense if and to the extent that such claim is finally determined to be a valid Indemnification Claim hereunder. No settlement of, or payment in respect of, any Third Party Claim involving liability of the Indemnitor under this Section 11.6(b) shall be made by or on behalf of the Indemnitee without the prior written consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed.

(c) Any entitlement of the Buyer Indemnities to be reimbursed for legal fees or related expenses in connection with a Third Party Claim shall be subject to the limitations set forth in Section 11.4 and the Sellers shall have no liability therefore except pursuant to the Indemnification Escrow.

11.7Subrogation. Upon payment in full of any Indemnification Claim or the payment of any judgment or settlement with respect to a Third Party Claim, the Indemnitor shall be subrogated to the extent of such payment to the rights of the Indemnitee against any Person with respect to the subject matter of such Indemnification Claim or Third Party Claim. The Indemnitee shall reasonably cooperate with the Indemnitor to pursue any claims against, or otherwise recover amounts from, any Person liable or responsible for any Losses for which indemnification has been received pursuant to this Agreement.

11.8Tax Effect, Mitigation, Insurance and Other Recoveries.

(a) All indemnification payments payable hereunder shall be reduced by the amount of insurance proceeds actually received by the Indemnitee as a result of the Loss for which the Indemnitee is seeking indemnification. Each Party agrees to promptly make a claim against any applicable insurance with respect to any Loss that would otherwise be payable pursuant to Section 11.2 or 11.3. Indemnification payments in Sections 11.2 and 11.3 shall be paid by the Indemnitor after reduction for any tax benefits actually realized by the Indemnitee as a result of the deductibility of any payment or accrual of the Loss in respect of such indemnification claim and shall be increased by the amount of any Tax detriment resulting from such indemnification claim (any such Tax benefit or Tax detriment being determined on a with and without basis). Any indemnification payment made hereunder shall be treated by the Parties, to the greatest extent allowed by applicable Legal Requirements, as an adjustment to the Purchase Price.

(b) Each Party shall use its commercially reasonable efforts to mitigate its Losses upon and after becoming aware of any event that could reasonably be expected to give rise to Losses that may be indemnifiable under this Article XI.

Any legal action, suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby shall be brought solely in the Chancery Court of the State of Delaware;provided, that if (and only after) such courts determine that they lack subject matter jurisdiction over any such legal action, suit or proceeding, such legal action, suit or proceeding shall be brought in the Federal courts of the United States located in the State of Delaware;provided,further, that if (and only after) both the Chancery Court of the State of Delaware and the Federal courts of the United States located in the State of Delaware determine that they lack subject matter jurisdiction over any such legal action, suit or proceeding, such legal action, suit or proceeding shall be brought in the United States District Court for the Southern District of New York.

12.10Specific Enforcement.

(a) Subject to Section 12.10(b), each Party acknowledges and agrees that the other Parties would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by the Parties could not be adequately compensated in all cases by monetary damages alone. Accordingly, subject to Section 12.10(b), in addition to any other right or remedy to which any Party may be entitled under this Agreement, at law or in equity, each Party shall be entitled to enforce any provision of this Agreement by

a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

(b) Notwithstanding the foregoing, it is explicitly agreed that Company shall only be entitled to seek specific performance of the obligations of Buyer, Intermediate Holdings or Merger Sub (other than Post-Closing Obligations) (i) to enforce specifically the terms and provisions of, and to prevent breaches of the covenants set forth in, Sections 6.1, 6.2 and 6.3 and (ii) to (x) enforce specifically the terms and provisions of, and to prevent breaches of the covenants, agreements and mechanics set forth in Article II necessary or required to effectuate the Merger and the Closing and (y) cause the Equity Financing to be funded to fund the Merger;provided, that in the case of each of the foregoing clauses (x) and (y), only in the event that (A) all conditions in Article VII have been satisfied (other than those conditions that (1) by their nature are to be satisfied by actions taken at the Closing or (2) are not satisfied solely as a result of a breach by Buyer, Intermediate Holdings or Merger Sub of their obligations under this Agreement) or, with respect to certificates to be delivered at the Closing, are capable of being satisfied upon the Closing) at the time when the Closing would have occurred but for the failure of the Equity Financing to be funded, (B) the financing provided for by the Debt Commitment Letter (or, if alternative financing is being used in accordance with Section 6.3, pursuant to the commitments with respect thereto) has been funded or will be funded at the Closing if the Equity Financing is funded at the Closing, and (C) the Company has irrevocably confirmed in writing to Buyer and Intermediate Holdings that if specific performance is granted and the Equity Financing and Debt Financing are funded, then the Closing pursuant to 2.12 will occur.

(c) Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief, on the terms set forth herein, 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 an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

12.11Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original of this Agreement and all of which, when taken together, shall be deemed to constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or electronic mail shall be effective as delivery of a manually executed counterpart of this Agreement.

12.12No Third Party Beneficiaries. Except as specifically set forth in Section 9.5, this Agreement is for the sole benefit of the Parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable benefit, claim, cause of action, remedy or right of any kind;provided, that except that the Financing Parties shall be express third party beneficiaries of Sections 10.2(c), 12.9(b) and 12.9(c).
