(i) Stock-Based Awards. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of Stock-Based Awards, each Stock-Based Award, if any, that was granted in accordance with Section 6.18(a) will be assumed by Parent and will continue to have, and be subject to, the same terms and conditions of such award immediately prior to the Effective Time, including the vesting restrictions, except that (x) each Stock-Based Award will be exercisable for a number of validly issued, fully paid and non-assessable shares of Parent Common Stock equal to the product of the number of Company Common Units subject to such award immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock, (y) if applicable, the per unit base or exercise price for the Parent Common Stock issuable upon exercise of such assumed Stock-Based Award will be equal to the quotient determined by dividing the per unit base or exercise price for such Stock-Based Award immediately prior to the Effective Time by the Exchange Ratio, rounded up to the nearest whole cent, and (z) all references to the “Company” in the Company Plan and the award agreements will be references to Parent.

To the extent that amounts are so withheld, such withheld amounts shall be timely paid to the applicable taxing authority and treated for all purposes of this Agreement as having been paid to the holder of such Company Options. As applicable, payment of the Per Unit Earn-Out Payment shall be made prior to the date that is five (5) years following the Effective Time and otherwise in accordance with Section 1.409A-3(i)(5)(iv)(A) of the Treasury Regulations or any successor thereto.

(iii) If determined by Parent in its sole discretion, following the Effective Time, in accordance with the NYSE listing standards, Parent will be able to grant stock-based awards under the terms of its 2011 Incentive Award Plan or another stock plan adopted by Parent to issue the reserved but unissued Company Common Units otherwise issuable under the Company Plan, except that (i) the equity interests covered by such awards will be shares of Parent Common Stock and (ii) the number of Company Common Units available for issuance shall be converted into a number of shares of Parent Common Stock equal to the product of the number of Company Common Units otherwise available for issuance under the Company Plan immediately prior to the Effective Time (after taking into consideration the number of Company Common Units

that will return to the Company Plan in connection with the cancellation of the Company Options contemplated by this Section) multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock (the “Available Reserve”); provided, however, that the Available Reserve shall in no event exceed 1,500,000 shares of Parent Common Stock. In accordance with the NYSE listing standards, the time during which such shares of Parent Common Stock are available will not be extended beyond the period when they would have otherwise been available under the Company Plan, absent the Merger, and no stock-based awards will be granted by Parent to individuals who were employed, immediately before the transaction, by Parent or any of the Parent Subsidiaries in existence immediately prior to the Effective Time. As soon as practicable following the Effective Time, but in any event within ten (10) Business Days thereafter, Parent shall prepare and file with the SEC a registration statement on Form S-8 covering the assumed Stock-Based Awards, if any, and the Available Reserve, if any, and Parent shall cause the same to become effective.

(iv) Notwithstanding the preceding subparagraph (iii), if Parent obtains a recommendation by Institutional Shareholder Services, a proxy advisory subsidiary of MSCI Inc. (“ISS”), of a vote “for” the amendment to its 2011 Incentive Award Plan described in Parent’s Proxy Statement for its 2012 Annual Stockholder Meeting, Parent shall not assume the Available Reserve or otherwise be able to grant any stock-based awards as of or following the Effective Time or cause the Company under the terms hereof to grant any stock-based awards prior to or as of the Effective Time, in each case attributable to the reserved but unissued Company Common Units otherwise issuable under the Company Plan immediately prior to the Effective Time.

(v) Prior to the Effective Time, the Company shall take any and all action necessary or reasonably requested by Parent to effect the assumption of the Stock-Based Awards and the cancellation and cash-out of the Company Options and in furtherance of preserving and assuming the Available Reserve, including adopting all resolutions, giving all notices, obtaining any written consents, and taking any other actions that are necessary or appropriate to effectuate this Section 3.01(b). Any notices, consents, or other communications to holders of Stock-Based Awards or Company Options will be subject to the review and approval of Parent, which shall not be unreasonably withheld, conditioned, or delayed. No awards shall be granted pursuant to the Company Plan following the Effective Time.

(c) Estimated Amounts Included In Closing Merger Consideration. No later than five (5) Business Days prior to the Closing Date, the Company shall prepare and deliver to Parent (i) an estimated consolidated balance sheet of the Business Entities and Related Consolidated Entities as of immediately prior to the Effective Time (the “Estimated Closing Balance Sheet”) and (ii) a statement derived from such estimated consolidated balance sheet (the “Estimated Adjustment Statement”) setting forth the Company’s good faith estimates of the Net Working Capital of the Business Entities and Related Consolidated Entities (such estimates, the “Estimated Net Working Capital”) and the Indebtedness Amount (the “Estimated Indebtedness Amount”), in each case as of immediately prior to the Effective Time. The Estimated Closing Balance Sheet and the Estimated Adjustment Statement shall be prepared in a manner consistent with Exhibit B and in accordance with GAAP, applied on a basis consistent with the Audited

Financial Statements, and include reasonable detail with respect to the calculation of each component of the Estimated Net Working Capital and the Estimated Indebtedness Amount; provided that Estimated Net Working Capital and Estimated Indebtedness Amount shall be calculated in accordance with the definitions of those terms herein. The Company and Parent shall use good faith efforts to resolve prior to the Closing any disagreements between them concerning the computation of any of the items on the Estimated Closing Balance Sheet or the Estimated Adjustment Statement; provided, however, if the parties are unable to resolve any such disagreement, any item in dispute shall be deemed (solely for purposes of determining the Closing Merger Consideration, but subject in all respects to adjustment pursuant to Section 3.05) equal to the sum of (x) the estimate prepared in good faith by the Company and (y) Parent’s good faith estimate of such item, divided by two. If the Estimated Net Working Capital minus the Estimated Indebtedness Amount is less than the Target (such deficiency stated as a positive number, the “Estimated Shortfall Amount”), then the Closing Merger Consideration shall be decreased by an amount equal to the Estimated Shortfall Amount and the Per Unit Closing Consideration shall be decreased by an amount equal to the Estimated Shortfall Amount divided by the Total Outstanding Company Units.

(d) Dissenting Units. Notwithstanding anything in this Agreement to the contrary, Company Common Units that are issued and outstanding immediately prior to the Effective Time and that are held by Members properly exercising dissenter’s rights available under the Dissenter’s Act (the “Dissenting Units”) shall be converted into the right to receive payment from the Surviving Entity with respect thereto and shall not be converted into or be exchangeable for the right to receive cash or shares of Parent Common Stock unless and until such holders shall have failed to perfect or shall have effectively withdrawn or lost their rights to appraisal under the Dissenter’s Act. Dissenting Units shall be treated in accordance with the Dissenter’s Act. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right to appraisal, such holder’s Company Common Units shall thereupon be converted into and become exchangeable only for the right to receive, as of the Effective Time, cash or shares of Parent Common Stock in accordance with the terms of this ARTICLE III. The Company shall give Parent: (i) prompt notice of any written demands for appraisal of any Company Common Units, any attempted withdrawals of such demands, and any other instruments served pursuant to the Dissenter’s Act and received by the Company relating to rights to be paid the “fair value” of Dissenting Units, as provided in the Dissenter’s Act; and (ii) the opportunity to participate in, and, after the Closing, direct, all negotiations and Actions with respect to demands for appraisal under the Dissenter’s Act. The Company shall not, except with the prior written consent of Parent, voluntarily make or agree to make any payment with respect to any demands for appraisal of Company Common Units. The Company or the Surviving Entity, as applicable under the Dissenter’s Act, shall comply with all notice requirements under the Dissenter’s Act.

(e) Rights as Unitholders; Unit Transfers. From and after the Effective Time, Company Common Units shall be no longer outstanding and shall automatically be canceled and shall cease to exist, and Members will have no rights as unitholders of the Company, other than rights to receive (without interest) (i) any then-unpaid dividend or other distribution with respect to such Company Common Units having a record date before the Effective Time and (ii) the consideration to which such holders are entitled in accordance with this ARTICLE III (or as to Dissenting Units, such rights as provided by the CLLCA). After the Effective Time, there will be

no transfers of Company Common Units on the unit transfer books of the Company or the Surviving Entity, and Company Common Units presented to Parent or the Surviving Entity for any reason will be canceled and exchanged in accordance with this ARTICLE III. Notwithstanding anything in this Section 3.01 to the contrary, at the Effective Time and by virtue of the Merger, each Company Common Unit beneficially owned by the Company (other than units held in a trust, fiduciary, or nominee capacity or as a result of debts previously contracted) or held in the Company’s treasury will be canceled and retired and will cease to exist, and no shares of Parent Common Stock or any other consideration will be issued or paid in exchange therefor.

(f) Anti-Dilution Adjustments. If Parent changes (or the Parent Board sets a related record date that will occur before the Effective Time for a change in) the number or kind of shares of Parent Common Stock outstanding by way of a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction, then the Aggregate Parent Share Number, the Closing Price, and the Exchange Ratio (and any other dependent items) will be adjusted proportionately to account for such change. If the Company changes (or the Company Board sets a related record date that will occur before the Effective Time for a change in) the number or kind of Company Common Units (or rights thereto) outstanding by way of a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction, then the aggregate per unit exercise price of all Company Options (and any other dependent items) will be adjusted proportionately to account for such change.

(g) Merger Sub Units. Each unit of membership interest in Merger Sub (a “Merger Sub Unit”) issued and outstanding immediately prior to the Effective Time will be converted into one common unit of the Surviving Entity.

(h) Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Parent Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. Instead, Parent will pay to each holder of Company Common Units who would otherwise be entitled to a fractional share of Parent Common Stock an amount in cash (without interest) determined by multiplying such fraction of a share of Parent Common Stock by the Closing Price.

(a) A portion of the Closing Merger Consideration equal to the Escrow Amount shall constitute escrowed merger consideration (collectively with any earnings or dividends or other distributions thereon, if any, the “Escrowed Merger Consideration”). The Escrowed Merger Consideration shall be withheld from the Closing Merger Consideration otherwise deliverable to the Members and holders of Company Options on the Closing Date to serve as security for the benefit of Parent (on behalf of itself or any other Parent Indemnified Party) against (x) the indemnification afforded the Parent Indemnified Parties by ARTICLE VIII of this Agreement and (y) any reduction in the Aggregate Final Per Unit Merger Consideration or the Aggregate Final Per Option Merger Consideration made pursuant to Section 3.05(f). The Escrowed Merger Consideration shall consist of cash and Parent Common Stock in the Escrow Proportion, with each share of Parent Common Stock valued for these purposes at the One Day Parent Stock Volume-Weighted Average Price as of the Closing Date. On the Closing Date, the

Escrowed Merger Consideration shall be deposited by Parent with the Escrow Agent in an escrow account (the “Escrow Account”) established in accordance with an escrow agreement to be entered into among Parent, the Member Representative, and the Escrow Agent, consistent with the terms set forth in this Agreement and other customary terms and conditions for similar agreements (the “Escrow Agreement”). The Escrow Agreement shall provide that Parent is, for federal income tax purposes, the owner of the Escrowed Merger Consideration and is taxable on any earnings thereon. If any payment is required to be made to Parent pursuant to this Section 3.02, Parent and the Member Representative shall promptly provide written instructions to the Escrow Agent, pursuant to the terms of the Escrow Agreement, to deliver to Parent out of the Escrow Fund an amount of cash and Parent Common Stock, in the Escrow Proportion (to the extent possible and so as not to create fractional shares of Parent Common Stock), that in the aggregate is equal in value to such required payment, with each share of Parent Common Stock valued for these purposes at the One Day Parent Stock Volume-Weighted Average Price as of the date of such distribution.

(b) On the Survival End Date (the “First Escrow Distribution Date”), the Escrow Agent shall create two additional separate escrow accounts. The Escrow Agent shall deposit from the Escrow Account into the first additional account (the “Healthcare Indemnity Account”) the First Tranche Healthcare Escrowed Merger Consideration. The Escrow Agent shall deposit from the Escrow Account into the second additional account (the “Tax Indemnity Account”) the First Tranche Tax Escrowed Merger Consideration. In addition, no later than the second (2nd) Business Day following the Survival End Date, Parent and the Member Representative shall provide written instructions to the Escrow Agent, pursuant to the terms of the Escrow Agreement, to deliver to the Members and to the Company for proper payment to the holders of the Company Options as of the Closing, no later than the fifth (5th) Business Day following the First Escrow Distribution Date, any Escrowed Merger Consideration remaining in the Escrow Account other than the First Tranche Healthcare Escrowed Merger Consideration deposited in the Healthcare Indemnity Account and the First Tranche Tax Escrowed Merger Consideration deposited in the Tax Indemnity Account (the “First Distribution Escrowed Merger Consideration”) as follows: (i) the aggregate amount of First Distribution Escrowed Merger Consideration that consists of Parent Common Stock to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, (ii) the aggregate amount of dividends or other distributions made on Parent Common Stock, or earnings on such dividends or other distributions, held in escrow to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, and (iii) the aggregate amount of First Distribution Escrowed Merger Consideration that consists of cash (other than cash amounts set forth in clause (ii) above), including all earnings on Escrowed Merger Consideration that consists of cash held in escrow, to the Members who held Cash Equivalency Units as of the Closing and the holders of Company Options pro rata based on the Cash Equivalency Units held by such Members and holders of Company Options as of the Closing, it being understood that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G); provided that, if on the First Escrow Distribution Date any claim for indemnification by any Parent Indemnified Party under Section 8.02 is outstanding, then such amount of cash and Parent Common Stock, in the Escrow Proportion (to the extent possible and so as not to create fractional shares of Parent Common Stock), that in the aggregate is equal in value to the amount that may be reasonably necessary to satisfy such claim (or, if such amount is

greater than the amount remaining in the Escrow Account, then the amount of cash and Parent Common Stock remaining in the Escrow Account), with each share of Parent Common Stock valued for these purposes at the One Day Parent Stock Volume-Weighted Average Price as of the First Escrow Distribution Date, shall not be distributed pursuant to this Section 3.02 for so long as such claim is outstanding and, following resolution of such claim, any amount remaining in the Escrow Account that was held back shall be distributed in accordance with clauses (i), (ii) and (iii) above.

(c) No later than the second (2nd) Business Day following the first (1st) anniversary of the Survival End Date (such first anniversary, the “Second Escrow Distribution Date”), Parent and the Member Representative shall provide written instructions to the Escrow Agent, pursuant to the terms of the Escrow Agreement, to deliver to the Members and to the Company for proper payment to the holders of the Company Options as of the Closing, no later than the fifth (5th) Business Day following the Second Escrow Distribution Date, any Escrowed Merger Consideration in the Healthcare Indemnity Account in excess of the Second Tranche Healthcare Escrowed Merger Consideration (the “Second Distribution Escrowed Merger Consideration”) as follows: (i) the aggregate amount of Second Distribution Escrowed Merger Consideration in the Healthcare Indemnity Account that consists of Parent Common Stock to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, (ii) the aggregate amount of dividends or other distributions made on Parent Common Stock, or earnings on such dividends or other distributions, held in the Healthcare Indemnity Account to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, and (iii) the aggregate amount of Second Distribution Escrowed Merger Consideration in the Healthcare Indemnity Account that consists of cash (other than cash amounts set forth in clause (ii) above), including all earnings on Escrowed Merger Consideration that consists of cash held in the Healthcare Indemnity Account, to the Members who held Cash Equivalency Units as of the Closing and the holders of Company Options pro rata based on the Cash Equivalency Units held by such Members and holders of Company Options as of the Closing, it being understood that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G); provided that, if on the Second Escrow Distribution Date any claim for indemnification of the type described in Section 8.04(a)(v) is outstanding, then such amount of cash and Parent Common Stock, in the Escrow Proportion (to the extent possible and so as not to create fractional shares of Parent Common Stock), that in the aggregate is equal in value to the amount that may be reasonably necessary to satisfy such claim (or, if such amount is greater than the amount remaining in the Healthcare Indemnity Account, then the amount of cash and Parent Common Stock remaining in the Healthcare Indemnity Account), with each share of Parent Common Stock valued for these purposes at the One Day Parent Stock Volume-Weighted Average Price as of the Second Escrow Distribution Date, shall not be distributed pursuant to this Section 3.02 for so long as such claim is outstanding and, following resolution of such claim, any amount remaining in the Healthcare Indemnity Escrow Account that was held back shall be distributed in accordance with clauses (i), (ii) and (iii) above.

(f) No later than the second (2nd) Business Day following October 15, 2017 (October 15, 2017 being referred to herein as the “Fifth Escrow Distribution Date”), Parent and the Member Representative shall provide written instructions to the Escrow Agent, pursuant to the terms of the Escrow Agreement, to deliver to the Members and to the Company for proper payment to the holders of the Company Options as of the Closing, no later than the fifth (5th) Business Day following the Fifth Escrow Distribution Date, (i) the aggregate amount of remaining Escrowed Merger Consideration in the Tax Indemnity Account that consists of Parent Common Stock to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, (ii) the aggregate amount of dividends or other distributions made on Parent Common Stock, or earnings on such dividends or other distributions, held in the Tax Indemnity Account to the Members who held Stock Equivalency Units as of the Closing pro rata based on the Stock Equivalency Units held by such Members as of the Closing, and (iii) the aggregate amount of remaining Escrowed Merger Consideration in the Tax Indemnity Account that consists of cash (other than cash amounts set forth in clause (ii) above), including all earnings on Escrowed Merger Consideration that consists of cash held in the Tax Indemnity Account, to the Members who held Cash Equivalency Units as of the Closing and the holders of Company Options pro rata based on the Cash Equivalency Units held by such Members and holders of Company Options as of the Closing, it being understood that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G); provided that, if on the Fifth Escrow Distribution Date any claim for indemnification of the type described in Section 8.04(a)(vi) is outstanding, then such amount of cash and Parent Common Stock, in the Escrow Proportion (to the extent possible and so as not to create fractional shares of Parent Common Stock), that in the aggregate is equal in value to the amount that may be reasonably necessary to satisfy such claim (or, if such amount is greater than the amount remaining in the Tax Indemnity Account, then the amount of cash and Parent Common Stock remaining in the Tax Indemnity Account), with each share of Parent Common Stock valued for these purposes at the One Day Parent Stock Volume-Weighted Average Price as of the Fifth Escrow Distribution Date, shall not be distributed pursuant to this Section 3.02 for so long as such claim is outstanding and, following resolution of such claim, any amount remaining in the Tax Indemnity Escrow Account shall be distributed in accordance with clauses (i), (ii) and (iii) above.

(g) For the avoidance of doubt, (A) holders of Company Options, in their capacity solely as holders of Company Options, shall bear responsibility for a portion of the indemnification obligations, if any, of the Members under ARTICLE VIII solely and exclusively through distributions from the Escrow Account, the Healthcare Indemnity Account, and the Tax Indemnity Account as set forth in this Section 3.02, and (B) following the distribution of all Escrowed Merger Consideration from the Escrow Account, the Healthcare Indemnity Account, and the Tax Indemnity Account in accordance with this Section 3.02, the holders of Company Options, in their capacity solely as holders of Company Options, shall bear no further indemnification obligations pursuant to this Agreement. The parties hereto understand and agree that the contingent rights to receive any Escrowed Merger Consideration are not transferable, except pursuant to a reorganization, liquidation, or other similar transfer of the assets of the relevant party to its equityholders or a successor entity or by operation of Laws relating to descent and distribution, divorce, and community property.

(a) Election Form. An election form and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery to the Exchange Agent), in such form as the Company and Parent shall mutually agree (the “Election Form”), shall be mailed on a date that is not less than thirty (30) days prior to the anticipated Effective Time (such date, the “Mailing Date”) to each holder of record of Company Common Units as of five (5) Business Days prior to the Mailing Date (the “Election Form Record Date”). The Company shall use its commercially reasonable efforts to make available as many Election Forms as may be reasonably requested by all persons who are holders (or beneficial owners) of Company Common Units on the Election Form Record Date or who become holders (or beneficial owners) of Company Common Units after the Election Form Record Date and prior to the close of business on the Business Day immediately prior to the Election Deadline. The Company shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein.

(b) Choice of Election. Each Election Form shall permit such holder, subject to the allocation and election procedures set forth in this Section 3.03, (i) to elect to receive an amount of cash equal to the Per Unit Closing Consideration for all of the Company Common Units held by such holder (a “Cash Election”), (ii) to elect to receive the Per Unit Closing Stock Consideration for all of such units (a “Stock Election”), (iii) to elect to receive the Per Unit Closing Stock Consideration for a certain number of such holder’s units and an amount of cash equal to the Per Unit Closing Consideration for all other units of such holder’s units (a “Mixed Election”), or (iv) to indicate that such record holder has no preference as to the receipt of cash or Parent Common Stock for such units. A holder of record of Company Common Units who holds such units as nominee, trustee, or in another representative capacity (a “Unitholder Representative”) (which shall include, for the avoidance of doubt, the Majority Member and Bay Shores Investment LLC) may submit multiple Election Forms; provided that each such Election Form covers all the Company Common Units held by such Unitholder Representative for a particular beneficial owner; provided, further, that the Unitholder Representative shall permit the

holders of its equity securities to direct it to make an election in accordance with the terms of its governing documents and the Unitholder Representative shall make an election that reflects such election by the holders of its equity securities. Company Common Units as to which a Cash Election (including pursuant to a Mixed Election) has been made are referred to herein as “Cash Election Units.” Company Common Units as to which a Stock Election has been made (including, pursuant to a Mixed Election) are referred to as “Stock Election Units.” Company Common Units as to which no election has been made (or as to which an Election Form is not returned properly completed) are referred to herein as “Non-Election Units.”

(c) Non-Election; Dissenting Units. Any Company Common Units with respect to which the holder thereof shall not, as of the Election Deadline, have made an election by submission to the Exchange Agent of an effective, properly completed Election Form shall be deemed Non-Election Units. All Dissenting Units shall be deemed units subject to a Cash Election, and with respect to such units the holders thereof shall in no event receive consideration comprised of Parent Common Stock, except as provided in Section 3.03(h) hereof; provided, however, that for purposes of making the proration calculations provided for in this Section 3.03, only Dissenting Units as existing at the Effective Time shall be deemed Cash Election Units.

(d) Effectiveness; Election Deadline. To be effective, a properly completed Election Form shall be submitted to the Exchange Agent on or before 5:00 p.m., New York City time, on the second (2nd) Business Day prior to the Effective Time (or such other time and date as Parent and the Company may mutually agree) (the “Election Deadline”). An election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by duly executed transmittal materials included with the Election Form. Any Election Form may be revoked or changed by the person submitting such Election Form to the Exchange Agent by written notice to the Exchange Agent only if such notice of revocation or change is actually received by the Exchange Agent at or prior to the Election Deadline. If a Member either (i) does not submit a properly completed Election Form in a timely fashion or (ii) revokes its Election Form prior to the Election Deadline (without later submitting a properly completed Election Form prior to the Election Deadline), the Company Common Units held by such Member shall be designated as Non-Election Units. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, modification, or revocation has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent, the Company or the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form. All Elections (whether Cash Elections, Stock Elections, or Mixed Elections) shall be revoked automatically if the Exchange Agent is notified in writing by Parent or the Company, upon exercise by Parent or the Company of its respective or their mutual rights to terminate this Agreement to the extent provided under ARTICLE IX, that this Agreement has been terminated in accordance with ARTICLE IX.

(e) Maximum Stock Election. If a Member makes a Stock Election for a number of Company Common Units in excess of such Member’s Maximum Stock Election Eligible Units, then such Member shall be deemed to have made a Stock Election with respect to

a number of Company Common Units equal to such Member’s Maximum Stock Election Eligible Units and a Cash Election with respect to all other of such Member’s Company Common Units.

(f) Stock Elections Equal to Unit Conversion Number. Notwithstanding any other provision contained in this Agreement, the total number of Company Common Units to be converted into the right to receive the Per Unit Closing Stock Consideration pursuant to Section 3.01(a)(i) (the “Unit Conversion Number”) shall be equal to the quotient obtained by dividing (x) the Aggregate Parent Share Number by (y) the Exchange Ratio. Each other Company Common Unit (other than Dissenting Units) shall be converted into an amount of cash equal to the Per Unit Closing Consideration.

(g) Stock Consideration Proration. If the aggregate number of Company Common Units with respect to which Stock Elections shall have been validly made (the “Stock Election Number”) exceeds the Unit Conversion Number, then all Cash Election Units and all Non-Election Units of each holder thereof shall be converted into the right to receive an amount of cash equal to the Per Unit Closing Consideration, and Stock Election Units of each holder thereof will be converted into the right to receive the Per Unit Closing Stock Consideration in respect of that number of Stock Election Units equal to the product obtained by multiplying (x) the number of Stock Election Units held by such holder by (y) a fraction, the numerator of which is the Unit Conversion Number and the denominator of which is the Stock Election Number, with each of such holder’s remaining Stock Election Units being converted into the right to receive an amount of cash equal to the Per Unit Closing Consideration.

(h) Cash Consideration Proration. If the Stock Election Number is less than the Unit Conversion Number (the amount by which the Unit Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Units shall be converted into the right to receive the Per Unit Closing Stock Consideration, and the Non-Election Units and Cash Election Units shall be treated in the following manner:

(i) If the Shortfall Number is less than or equal to the number of Non-Election Units, then all Cash Election Units shall be converted into the right to receive an amount of cash equal to the Per Unit Closing Consideration, and the Non-Election Units of each holder thereof shall convert into the right to receive the Per Unit Closing Stock Consideration in respect of that number of Non-Election Units equal to the product obtained by multiplying (A) the number of Non-Election Units held by such holder by (B) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Units, with each of such holder’s remaining Non-Election Units being converted into the right to receive an amount of cash equal to the Per Unit Closing Consideration; or

(ii) If the Shortfall Number exceeds the number of Non-Election Units, then all Non-Election Units shall be converted into the right to receive the Per Unit Closing Stock Consideration, and the Cash Election Units of each holder thereof shall be converted into the right to receive the Per Unit Closing Stock Consideration in respect of that number of Cash Election Units equal to the product obtained by multiplying (A) the

number of Cash Election Units held by such holder by (B) a fraction, the numerator of which is the amount by which (x) the Shortfall Number exceeds (y) the total number of Non-Election Units and the denominator of which is the total number of Cash Election Units, with each of such holder’s remaining Cash Election Units being converted into the right to receive an amount of cash equal to the Per Unit Closing Consideration.

(iii) Notwithstanding clauses (i) and (ii) above, if as a result of the application of clause (i) or (ii) above, any Member shall be making a Stock Election for a number of Company Common Units in excess of such Member’s Maximum Stock Election Eligible Units, then such Member shall instead be deemed to have made a Stock Election with respect to a number of Company Common Units equal to such Member’s Maximum Stock Election Eligible Units and a Cash Election with respect to all other of such Member’s Company Common Units, and the resulting Shortfall Number shall be reallocated to the other Members’ Non-Election Units and Cash Election Units in the manner set forth in clause (i) and (ii) above, with references to “Non-Election Units” and “Cash Election Units” in such clauses (i) and (ii) being deemed for purposes of this reallocation to exclude Non-Election Units and Cash Election Units held by any Member that has made, or has been deemed to have made, a Stock Election equal to such Member’s Maximum Stock Election Eligible Units.

(a) Appointment of Exchange Agent. After the Election Deadline and no later than the Closing Date and until the date that is one hundred eighty (180) days after the Effective Time, Parent shall deposit, or cause to be deposited, with an exchange agent agreed upon by Parent and the Company (the “Exchange Agent”) (i) cash in an amount sufficient to allow the Exchange Agent to make all payments that may be required pursuant to this ARTICLE III; provided that (1) pursuant to Section 3.02 the Escrow Amount consisting of cash shall be delivered by Parent to the Escrow Agent to be held pursuant to the Escrow Agreement, (2) pursuant to Section 3.07 the MR Escrow Amount shall be delivered by Parent to the Escrow Agent to be held pursuant to the MR Escrow Agreement, (3) pursuant to Section 3.08 the Nevada Escrow Amount shall be delivered by Parent to the Escrow Agent to be held pursuant to the Nevada Escrow Agreement, and (4) the aggregate amount of cash payable in respect of all Company Options pursuant to Section 3.01(b)(ii)(A) shall be delivered by Parent to the Company for proper payment to the holders of Company Options, and (ii) certificates, or at Parent’s option, evidence of shares in book entry form, representing the Aggregate Parent Share Number of shares of Parent Common Stock (“New Certificates”), to be given to the holders of Company Common Units in exchange for their units pursuant to this ARTICLE III; provided that pursuant to Section 3.02 the Escrow Amount consisting of Parent Common Stock shall be delivered by Parent to the Escrow Agent to be held pursuant to the Escrow Agreement. On the date that is one hundred eighty (180) days after the Effective Time, any such cash or New Certificates remaining in the possession of the Exchange Agent (together with any earnings in respect thereof) shall be delivered to (or as directed by) Parent. Any holder of Company Common Units who has not theretofore exchanged his, her, or its Company Common Units pursuant to this ARTICLE III shall thereafter be entitled to look exclusively to Parent, and only as a general creditor thereof, for the consideration to which he, she, or it may be entitled upon exchange of such Company Common Units pursuant to this ARTICLE III. Notwithstanding the

foregoing, neither the Exchange Agent nor any party hereto shall be liable to any holder of Company Common Units for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat, or similar laws.

(b) Exchange Procedures for Company Common Units. Promptly after the Effective Time, but in no event later than ten (10) days thereafter, the Surviving Entity shall cause the Exchange Agent to mail or deliver to each person who was, immediately prior to the Effective Time, a holder of record of Company Common Units a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery to the Exchange Agent) containing instructions for use in effecting exchange for the consideration to which such person may be entitled pursuant to this ARTICLE III. Upon surrender to the Exchange Agent of a letter of transmittal duly executed and completed in accordance with the instructions thereto, the holder of such Company Common Units shall promptly be provided in exchange therefor, but in no event later than ten (10) Business Days after due surrender, a New Certificate and a check, ACH payment, or a wire transfer in the amount to which such holder is entitled pursuant to this ARTICLE III, and the Company Common Units so surrendered shall forthwith be canceled. No interest will accrue or be paid with respect to any cash or other property to be delivered upon surrender of any Company Common Units. Each of Parent and the Surviving Entity shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Units such amounts as it may be required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local, or foreign Tax law. To the extent that amounts are so withheld by Parent, the Surviving Entity, or the Exchange Agent, as the case may be, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of Company Common Units in respect of which the deduction and withholding was made by Parent, the Surviving Entity, or the Exchange Agent, as the case may be, and such amounts shall be timely delivered by Parent, the Surviving Entity, or the Exchange Agent, as the case may be, to the applicable taxing authority.

(c) Transfer to Holder other than Existing Holder. If any cash payment is to be made in a name other than that in which the Company Common Units surrendered in exchange therefor is registered, it shall be a condition of such exchange that the person requesting such exchange shall pay any transfer or other Taxes required solely by reason of the making of such payment in a name other than that of the registered holder of the Company Common Units surrendered, or required for any other reason relating to such holder or requesting person, or shall establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable. If any New Certificate representing shares of Parent Common Stock is to be issued in a name other than that of the registered holder of the Company Common Units surrendered in exchange therefor, it shall be a condition of such issuance that the Company Common Units so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required solely by reason of the issuance of a certificate representing Company Common Units in a name other than that of the registered holder of the Company Common Units surrendered, or required for any other reason relating to such holder or requesting person, or shall establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) Dividends. No dividends or other distributions with a record date after the Effective Time with respect to Parent Common Stock shall be paid to the holder of any unsurrendered Company Common Units until the holder thereof shall surrender such Company Common Units in accordance with this ARTICLE III. After the surrender of a Company Common Unit in accordance with this ARTICLE III, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the shares of Parent Common Stock represented by the New Certificate.

(e) Lost, Stolen or Destroyed Certificates. If any certificate evidencing a Company Common Unit or Company Option shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen, or destroyed and, if required by Parent or the Exchange Agent, the posting by such person of a bond in such reasonable amount as Parent or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such certificate, Parent or the Exchange Agent shall, in exchange for such lost, stolen, or destroyed certificate, pay or cause to be paid the consideration deliverable in respect of the Company Common Units or Company Options formerly represented by such certificate pursuant to this ARTICLE III.

(a) As soon as practicable, but in no event later than ninety (90) days after the Closing Date, Parent shall prepare and deliver to the Member Representative the following (collectively, the “Preliminary Adjustment Statement”):

(i) an unaudited consolidated balance sheet of the Business Entities and Related Consolidated Entities as of immediately prior to the Effective Time (the “Preliminary Closing Balance Sheet”), prepared by Parent in accordance with GAAP, applied on a basis consistent with the Audited Financial Statements; and

(ii) a statement setting forth reasonably detailed calculations by Parent of the Net Working Capital and the Indebtedness Amount, in each case as of immediately prior to the Effective Time based on the Preliminary Closing Balance Sheet (the “Closing Adjustment Amounts”) and prepared in a manner consistent with Exhibit B and in accordance with GAAP, applied on a basis consistent with the Audited Financial Statements; provided that Net Working Capital and Indebtedness Amount shall be calculated in accordance with the definitions of those terms herein.

(b) If the Member Representative disagrees with the Preliminary Closing Balance Sheet or Parent’s calculation of the Closing Adjustment Amounts, the Member Representative shall promptly, but in no event later than forty-five (45) days after receiving the Preliminary Adjustment Statement (the “Review Period”), deliver to Parent written notice describing in reasonable detail its dispute by specifying those items or amounts as to which the Member Representative disagrees, together with the Member Representative’s determination of

such disputed items and amounts (a “Disagreement Notice”). If the Member Representative either gives notice that it agrees with Parent’s calculation of the Closing Adjustment Amounts or fails to deliver a Disagreement Notice within the Review Period, Parent and the Member Representative agree that effective as of the date of delivery of the notice of agreement or as of the close of business on the last day of the Review Period, as applicable, the Closing Adjustment Amounts set forth in the Preliminary Adjustment Statement shall be final, conclusive, and binding on Parent, the Company, and the Members and shall constitute the respective “Final Adjustment Amounts” for purposes of Section 3.05(b)(v). If the Member Representative delivers a Disagreement Notice to Parent within the Review Period, any item not expressly set forth in the Disagreement Notice as the subject of the disagreement shall be final, conclusive, and binding on Parent, the Company, and the Members, and the Member Representative and Parent shall resolve all disputed items set forth in the Disagreement Notice as follows:

(i) The Member Representative and Parent shall use reasonable good faith efforts to resolve the dispute during the thirty (30) day period (the “Resolution Period”) commencing on the date the Member Representative delivers the Disagreement Notice to Parent, and any such resolution shall be final and binding on Parent, the Company, and the Members. If the Member Representative and Parent are not able to resolve all disputed items within the Resolution Period, then the items in dispute shall be promptly submitted (if practicable, within five (5) Business Days following the expiration of the Resolution Period) to the Neutral Accountant.

(ii) The Neutral Accountant shall be given reasonable access to all relevant work papers, financial information, books, records, schedules, memoranda, and other documents prepared or reviewed by Parent or any of its accountants or other representatives that are relevant to the Preliminary Adjustment Statement, and to all personnel, including accounting personnel, involved in the preparation of the Preliminary Adjustment Statement, in connection with its calculation of the Closing Adjustment Amounts, provided that such access shall not include any access to documents to the extent prepared primarily in anticipation of, or for the purposes of evaluating, any potential dispute, litigation, or arbitration concerning the Preliminary Adjustment Statement or the calculation of the Closing Adjustment Amounts.

(iii) If any remaining items in dispute are submitted to the Neutral Accountant for resolution (such items, the “Unresolved Items”), each of Parent and the Member Representative shall submit to the Neutral Accountant (with a copy delivered to the other party on the same day), within ten (10) Business Days after the date of the engagement of the Neutral Accountant, a memorandum (which may include supporting exhibits) setting forth their respective positions on the Unresolved Items. Each of Parent and the Member Representative may (but shall not be required to) submit to the Neutral Accountant (with a copy delivered to the other party on the same day), within twenty (20) Business Days after the date of the engagement of the Neutral Accountant, a memorandum responding to the initial memorandum submitted to the Neutral Accountant by the other party. Unless requested by the Neutral Accountant in writing, no party hereto may present any additional information or arguments to the Neutral Accountant, either orally or in writing.

(iv) The Neutral Accountant shall use its accounting expertise to calculate, based solely on the written submissions of Parent, on the one hand, and the Member Representative, on the other hand, and not by independent investigation, the Closing Adjustment Amounts and shall be instructed that its calculation (i) must be made in accordance with the standards and definitions in this Agreement, and (ii) with respect to each item in dispute, must be within the range of values established for such amount as determined by reference to the value assigned to such amount by the Member Representative in the Disagreement Notice and by Parent in the Preliminary Adjustment Statement. The Neutral Accountant shall submit such verification and calculation to the Member Representative and Parent as soon as practicable, but in any event within thirty (30) days after the remaining issues in dispute are submitted to the Neutral Accountant. Notwithstanding anything express or implied in the first sentence of this Section 3.05(b)(iv) to the contrary, the determination by the Neutral Accountant of the Closing Adjustment Amounts, as set forth in a written notice delivered to Parent and the Member Representative by the Neutral Accountant in accordance with this Agreement, shall be binding and conclusive on Parent, the Company, and the Members.

(v) The Closing Adjustment Amounts as determined after all disputes have been resolved in accordance with this Section 3.05 are referred to herein collectively as the “Final Adjustment Amounts” and individually as the “Final Net Working Capital” and the “Final Indebtedness Amount,” respectively. The Member Representative and Parent agree that the procedures set forth in this Section 3.05 for resolving disputes with respect to the Preliminary Closing Balance Sheet and Closing Adjustment Amounts shall be the sole and exclusive method for resolving any such disputes. The Neutral Accountant’s determination may be entered and enforced in any court of competent jurisdiction, and the substance of the Neutral Accountant’s determination shall not be subject to review or appeal, absent a showing of fraud by one of the parties in the proceeding or on the part of the Neutral Accountant.

(c) The fees and expenses of the Neutral Accountant shall be borne equally by Parent and the Members, with the Members’ share of any such fees and expenses being paid from the MR Escrow Account.

(d) In connection with the Member Representative’s review of the Preliminary Adjustment Statement, Parent shall (a) provide reasonable access, during normal business hours and upon reasonable notice, to relevant work papers, financial information, books, records, schedules, memoranda, and other documents prepared or reviewed by Parent or any of its accountants or other representatives that are relevant to the Preliminary Adjustment Statement, and to all personnel, including accounting personnel, as are reasonably necessary or desirable with respect to the review of the Preliminary Adjustment Statement, and Parent shall provide such access promptly after a request is made by the Member Representative and/or its representatives (provided that such access shall not include any access to documents to the extent prepared primarily in anticipation of, or for the purposes of evaluating, any potential dispute, litigation or arbitration concerning the Preliminary Closing Balance Sheet or the calculation of the Closing Adjustment Amounts), and (b) subject to the foregoing limitations, request that Parent’s independent accountant, if any, communicate with the Member Representative and its representatives with respect to such review.

(e) It is the intent of the parties to have any determination of Unresolved Items by the Neutral Accountant proceed in an expeditious manner; however, any deadline or time period contained herein may be extended or modified by agreement of the parties and the parties agree that the failure of the Neutral Accountant to strictly conform to any deadline or time period contained herein shall not be a basis for seeking to overturn any determination rendered by the Neutral Accountant.

(f) If the Final Net Working Capital minus the Final Indebtedness Amount (each as determined pursuant to Section 3.05(b)), minus the Target, plus the Estimated Shortfall Amount is a (x) positive number (such excess, the “Total Adjustment Amount”), then the Aggregate Final Per Unit Merger Consideration and the Aggregate Final Per Option Merger Consideration to be paid by Parent shall be increased by the Final Per Unit Adjustment Payment or (y) a negative number (such deficit, the “Total Shortfall Amount”), then the Aggregate Final Per Unit Merger Consideration and the Aggregate Final Per Option Merger Consideration to be paid by Parent shall be decreased by the Final Per Unit Shortfall Amount. The amount of any reduction in the Aggregate Final Per Unit Merger Consideration or the Aggregate Final Per Option Merger Consideration to be made pursuant to this Section 3.05(f) shall be satisfied from the Escrow Fund in cash and Parent Common Stock pursuant to Section 3.02.

(g) The amount of any increase in the Aggregate Final Per Unit Merger Consideration and the Aggregate Final Per Option Merger Consideration to be made pursuant to Section 3.05(f) shall be paid to the Members and the holders of Company Options, pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units, as soon as reasonably practicable after the determination of the Final Adjustment Amounts and, in any event with respect to any such payment made to the Members, within five (5) Business Days thereafter; provided that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G).

(a) Earn-Out Payments. As additional merger consideration, at such times as provided in this Section 3.06, a total of up to $275,000,000 (the “Total Cash Earn-Out Consideration”), divided into two tranches, the first of which shall consist of $137,500,000 of the Total Cash Earn-Out Consideration (the “First Tranche”) and the second of which shall consist of $137,500,000 of the Total Cash Earn-Out Consideration (the “Second Tranche”) (each of the First Tranche and Second Tranche, an “Earn-Out Payment”), shall be payable to the Members, holders of Company Options and pursuant to Section 1(b) of the Nevada Settlement Agreements, subject to and in accordance with the terms and conditions of this Section 3.06.

(i) If the Earn-Out EBITDA for the fiscal year ended December 31, 2012 is equal to or greater than $550,000,000, then Parent shall pay to the Members and holders of Company Options the First Tranche in cash, which shall be allocated among the Members and holders of Company Options pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units; provided that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G).

(ii) If the Earn-Out EBITDA for the fiscal year ended December 31, 2013 is equal to or greater than $600,000,000, then (x) Parent shall pay to the Members and holders of Company Options the Second Tranche (less the aggregate amount payable pursuant to clause (y) below) in cash, which shall be allocated among the Members and the holders of Company Options pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units; provided that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G), and (y) Parent shall pay, or cause to be paid, any Nevada Second Tranche Payment that is due and payable pursuant to Section 1(b) of each of the Nevada Settlement Agreements.

(i) On or before the date that is ten (10) Business Days after Parent has filed its Annual Report on Form 10-K for each Calculation Period, Parent shall prepare and deliver to the Member Representative a written statement (in each case, an “Earn-Out Calculation Statement”) setting forth in reasonable detail its determination of Earn-Out EBITDA for the applicable Calculation Period and its calculation of the resulting Per Unit Earn-Out Payment (in each case, an “Earn-Out Calculation”).

(ii) The Member Representative shall have forty-five (45) days after receipt of the Earn-Out Calculation Statement for each Calculation Period (in each case, the “Earn-Out Review Period”) to review the Earn-Out Calculation Statement and the Earn-Out Calculation set forth therein. During the Earn-Out Review Period and solely for purposes reasonably related to the determinations of Earn-Out EBITDA and the resulting Per Unit Earn-Out Payment, the Member Representative and its accountants shall have reasonable access, during normal business hours and upon reasonable notice, to relevant work papers, financial information, books, records, schedules, memoranda, and other documents prepared or reviewed by Parent or any of its accountants or other representatives that are relevant to the Earn-Out Calculation Statement or the Earn-Out Calculation, and to all personnel, including accounting personnel, as are reasonably necessary or desirable with respect to the review of the Earn-Out Calculation Statement and the Earn-Out Calculation (provided that such access shall not include any access to documents to the extent prepared primarily in anticipation of, or for the purposes of evaluating, any potential dispute, litigation or arbitration concerning the Earn-Out Calculation Statement or the calculation of Earn-Out EBITDA). Prior to the expiration of the Earn-Out Review Period, the Member Representative may object to the Earn-Out Calculation set forth in the Earn-Out Calculation Statement for the applicable Calculation Period by delivering a written notice of objection (an “Earn-Out Calculation Objection Notice”) to Parent; provided that the only basis on which the Member Representative may dispute any matter in the Earn-Out Calculation is that Parent did not calculate the Earn-Out Calculation or Earn-Out EBITDA in a manner consistent with Exhibit B or in accordance with GAAP, applied on a basis consistent with the Audited Financial

Statements, or in accordance with the terms of this Agreement (including the applicable definitions and other terms hereof). Any Earn-Out Calculation Objection Notice shall specify the items in the applicable Earn-Out Calculation or calculation of Earn-Out EBITDA disputed by the Member Representative and shall describe in reasonable detail the basis for such objection, as well as the amount in dispute. If the Member Representative fails to deliver an Earn-Out Calculation Objection Notice to Parent prior to the expiration of the Earn-Out Review Period, then the Earn-Out Calculation set forth in the Earn-Out Calculation Statement shall be final and binding on Parent, the Company, and the Members. If the Member Representative timely delivers an Earn-Out Calculation Objection Notice, Parent and the Member Representative shall negotiate in good faith to resolve the disputed items and agree upon the resulting amount of Earn-Out EBITDA and the Per Unit Earn-Out Payment for the applicable Calculation Period. If Parent and the Member Representative are unable to reach agreement within fifteen (15) days after such an Earn-Out Calculation Objection Notice has been given, all unresolved disputed items shall be promptly referred to the Neutral Accountant. The Neutral Accountant shall be directed to render a written report on the unresolved disputed items with respect to the applicable Earn-Out Calculation and calculation of Earn-Out EBITDA as promptly as practicable, but in no event greater than thirty (30) days after such submission to the Neutral Accountant, and to resolve only those unresolved disputed items set forth in the Earn-Out Calculation Objection Notice. If unresolved disputed items are submitted to the Neutral Accountant, Parent and the Member Representative shall each furnish to the Neutral Accountant such work papers, schedules, and other documents and information relating to the unresolved disputed items as the Neutral Accountant may reasonably request. The Neutral Accountant shall resolve the disputed items based solely on the applicable definitions and other terms in this Agreement and the presentations by Parent and the Member Representative, and not by independent review. The resolution of the dispute and the calculation of Earn-Out EBITDA and the Per Unit Earn-Out Payment that is the subject of the applicable Earn-Out Calculation Objection Notice by the Neutral Accountant shall be final and binding on Parent, the Company and the Members. The fees and expenses of the Neutral Accountant shall be borne by the Members, with the Members’ share of any such fees and expenses being paid from the MR Escrow Account, and Parent in proportion to the amounts by which their respective calculations of Earn-Out EBITDA differ from Earn-Out EBITDA as finally determined by the Neutral Accountant.

(c) Independence of Earn-Out Payments. Parent’s obligation to pay each of the Per Unit Earn-Out Payments to the Members and holders of Company Options in accordance with Section 3.06(a) is an independent obligation of Parent and is not otherwise conditioned or contingent upon the satisfaction of any conditions precedent to any preceding or subsequent Per Unit Earn-Out Payment and the obligation to pay a Per Unit Earn-Out Payment to the Members and holders of Company Options shall not obligate Parent to pay any preceding or subsequent Per Unit Earn-Out Payment. For the avoidance of doubt and by way of example, if the conditions precedent to the payment of the Per Unit Earn-Out Payment for the first Calculation Period are not satisfied, but the conditions precedent to the payment of the Per Unit Earn-Out Payment for the second Calculation Period are satisfied, then Parent would be obligated to pay such Per Unit Earn-Out Payment for the second Calculation Period for which the corresponding conditions precedent have been satisfied, and not the Per Unit Earn-Out Payment for the first Calculation Period.

(d) Timing of Payment of Earn-Out Payments. Subject to Section 3.01(b)(ii)(G), any Per Unit Earn-Out Payment that Parent is required to pay pursuant to Section 3.06(a) hereof shall be paid in full no later than the later of (i) April 30 following the applicable Calculation Period and (ii) five (5) Business Days following the date upon which the determination of Earn-Out EBITDA for the applicable Calculation Period becomes final and binding upon the parties as provided in Section 3.06(b)(ii) (including any final resolution of any dispute raised by the Member Representative in an Earn-Out Calculation Objection Notice). Parent shall pay to the Members and holders of Company Options the applicable Per Unit Earn-Out Payment.

(e) Acceleration upon Parent’s Election. At any time after the Closing Date, Parent may, in its sole discretion, elect to make either or both of the following payments to the Members and the holders of Company Options: (i) a payment equal in amount to the First Tranche, discounted from April 30, 2013 back to the date of actual payment at a rate of 5% per annum, and (ii) a payment equal in amount to the Second Tranche, discounted from April 30, 2014 back to the date of actual payment at a rate of 5% per annum, it being understood that from the discounted Second Tranche amount, Parent shall pay, or cause to be paid, any Nevada Second Tranche Payment that is due and payable pursuant to Section 1(b) of each of the Nevada Settlement Agreements. Any such payment shall be made in cash, allocated among the Members and holders of Company Options pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units; provided that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G) and that any payment made pursuant to Section 1(b) of the Nevada Settlement Agreements shall be paid in accordance with such provision. Payment in full of the amount set forth in clause (i) above shall fully release and discharge Parent, its successors, and assigns from any further liability or obligation pursuant to this Section 3.06 in respect of the First Tranche. Payment in full of the amount set forth in clause (ii) above shall fully release and discharge Parent, its successors, and assigns from any further liability or obligation pursuant to this Section 3.06 in respect of the Second Tranche.

(f) Post-Closing Operation of the Company. Subject to the terms of this Agreement and the other Transaction Documents, subsequent to the Closing and through December 31, 2013, the chief executive officer and management of the Company shall operate the business of the Business Entities and Related Entities on an autonomous basis in a manner substantially consistent with their current operations. The chief executive officers of the Company and Parent shall collaborate on major decisions, consistent with appropriate corporate governance, including Parent’s corporate policy on acquisitions. Parent’s chief executive officer and the Parent Board shall retain ultimate decision-making authority as it relates to the business. Notwithstanding the above, to the extent Parent recommends taking or opposing any action or decision with respect to the business that would reasonably be expected to adversely impact any Earn-Out Payment and the Company’s chief executive officer is opposed to such Parent recommendation or decision, the Company’s chief executive officer has the right to request that the Parent Board decide the issue, in which case the matter shall be determined by the Parent

Board (and no such taking or opposing such action or decision shall be acted upon until such time as the Parent Board approves such taking or opposing such action or decision after considering in good faith the objections of the Company’s chief executive officer). In every event, Parent and the Company acknowledge that all decisions shall be made in compliance with applicable Law and in the best interests of the combined company consistent with the fiduciary duties of the officers and directors of the combined company. Further, in no event may Parent take any action, or fail to take any action, in bad faith with the intent of reducing or avoiding any of the Earn-Out Payments hereunder. Similarly, in no event may the management of the Company take any action not in the best interests of the combined company with the intent to ensure any of the Earn-Out Payments hereunder.

(g) No Security. The parties hereto understand and agree that (i) the contingent rights to receive any Per Unit Earn-Out Payment shall not be represented by any form of certificate or other instrument, are not transferable, except pursuant to a reorganization, liquidation, or other similar transfer of the assets of the relevant party to its equityholders or a successor entity or by operation of Laws relating to descent and distribution, divorce, and community property, and do not constitute an equity or ownership interest in Parent or the Company, (ii) neither Members nor holders of Company Options shall have any rights as a securityholder of Parent or the Company as a result of such contingent right of such Members or holders of Company Options to receive any Per Unit Earn-Out Payment hereunder, and (iii) no interest is payable with respect to any Per Unit Earn-Out Payment.

Section 3.07. Member Representative Escrow. A portion of the Closing Merger Consideration equal to the MR Escrow Amount shall constitute escrowed merger consideration (the “MR Escrowed Merger Consideration”). The MR Escrowed Merger Consideration shall be withheld from the Closing Merger Consideration otherwise deliverable to the Members and holders of Company Options on the Closing Date to fund, if necessary, (i) the amounts described in Section 3.05(c), Section 3.06(b)(ii), Section 3.08, Section 6.15(f), Section 8.08, and this Section 3.07 as being paid from the MR Escrow Account, (ii) the expenses incurred by the Member Representative acting in such capacity, and (iii) any other expense described in this Agreement as being paid from the MR Escrow Account. The MR Escrowed Merger Consideration shall consist entirely of cash. On the Closing Date, the MR Escrowed Merger Consideration shall be deposited by Parent with the Escrow Agent in an escrow account (the “MR Escrow Account”) established in accordance with an escrow agreement to be entered into between the Member Representative and the Escrow Agent, consistent with the terms set forth in this Agreement and other customary terms and conditions for similar agreements (the “MR Escrow Agreement”). The MR Escrow Agreement shall provide that the Members and the holders of Company Options are, for federal income tax purposes, the owners of the MR Escrowed Merger Consideration and are taxable on any earnings thereon, which tax shall be payable from the funds in the MR Escrow Account. If any payment is required to be made to or by the Member Representative acting in such capacity, the Member Representative shall provide written instructions to the Escrow Agent, pursuant to the terms of the MR Escrow Agreement, to deliver to the Member Representative or the third-party payee directed by the Member Representative, as the case may be, an amount of cash equal to such required payment. The MR Escrow Agreement shall provide that on the First Escrow Distribution Date (and on every anniversary of such date thereafter), the Member Representative

and Robert Margolis, M.D. (or his designated successor) shall mutually determine in good faith what, if any, amount of remaining funds in the MR Escrow Account should be distributed to the Members and the holders of Company Options; provided that all of the remaining funds in the MR Escrow Account (less any amounts required to pay outstanding and anticipated expenses) shall be distributed to the Members and the holders of Company Options no later than the fifth (5th) Business Day following the distribution of all remaining funds in the Escrow Account, the Healthcare Indemnity Account, and the Tax Indemnity Account to the Members and the holders of Company Options. To effectuate any distribution to the Members and the holders of the Company Options of funds from the MR Escrow Account, the Member Representative shall provide written instructions to the Escrow Agent to deliver to the Members and to the holders of the Company Options as of the Closing the aggregate amount of such distribution to the Members and the holders of Company Options pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units. The parties hereto understand and agree that the contingent rights to receive any funds from the MR Escrow Account are not transferable, except pursuant to a reorganization, liquidation, or other similar transfer of the assets of the relevant party to its equityholders or a successor entity or by operation of Laws relating to descent and distribution, divorce, and community property, and, in the event of any such transfer, the Member Representative shall be notified as promptly as reasonably practicable. The Member Representative shall provide the Majority Member with a written statement setting forth all distributions and payments made from the MR Escrow Account (including reasonable detail as to the purpose and amount of each such distribution or payment and the recipient thereof) for each month in which the MR Escrow Account is active, no later than twenty (20) Business Days following the end of such month. The Member Representative shall provide all Members with a written report for each year in which the MR Escrow Account is active, no later than ninety (90) days following the end of such year, setting forth (i) the amount of distributions and payments made from the MR Escrow Account during such year by category (specifically identifying payments made to the Member Representative or the Member Representative’s affiliated or related entities), (ii) the total amount of distributions and payments made from the MR Escrow Account during such year, (iii) the total earnings received on the funds in the MR Escrow Account during such year, and (iv) the funds remaining in the MR Escrow as of such year’s end, and attaching a copy of any annual statement received by the Member Representative from the Escrow Agent with respect to the MR Escrow Account. Upon the request of a Member or holder of Company Options, the Member Representative shall, or shall request the Escrow Agent to, provide such Member or holder of Company Options with such information regarding the MR Escrow Account, and any transaction activity relating thereto, as such Member or holder of Company Options may reasonably request and at such Member’s or holder of Company Options’ sole cost and expense.

Section 3.08. Nevada Escrow. A portion of the Closing Merger Consideration equal to the Nevada Escrow Amount shall constitute escrowed merger consideration (the “Nevada Escrowed Merger Consideration”). The Nevada Escrowed Merger Consideration shall be withheld from the Closing Merger Consideration otherwise deliverable to the Members and holders of Company Options on the Closing Date to fund, if applicable, certain transaction settlement payments that may become due and payable pursuant to Section 1(c) of each of the Nevada Settlement Agreements. The Nevada

Escrowed Merger Consideration shall consist entirely of cash. On the Closing Date, the Nevada Escrowed Merger Consideration shall be deposited by Parent with the Escrow Agent in an escrow account (the “Nevada Escrow Account”) established in accordance with an escrow agreement to be entered into among the Company, the Member Representative, and the Escrow Agent, consistent with the terms set forth in this Agreement and other customary terms and conditions for similar agreements (the “Nevada Escrow Agreement”). The Nevada Escrow Agreement shall provide that Parent is, for federal income tax purposes, the owner of the Nevada Escrowed Merger Consideration and is taxable on any earnings thereon. All fees, costs, and expenses (other than Taxes on any earnings) attributable to the establishment and maintenance of the Nevada Escrow Account shall be payable from the funds in the MR Escrow Account. If any transaction settlement payment becomes due and payable pursuant to Section 1(c) of either Nevada Settlement Agreement, the Company and the Member Representative shall promptly provide written instructions to the Escrow Agent, pursuant to the terms of the Nevada Escrow Agreement, to deliver to Company out of the funds in the Nevada Escrow Account an amount of cash equal to such required payment for the sole purpose of making such required payment pursuant to Section 1(c) of the applicable Nevada Settlement Agreement. If, pursuant to Section 1(c) of either Nevada Settlement Agreement, any transaction settlement payment will not be made because a condition precedent is not met (after giving effect to the shortfall provision contained therein), then the Company and the Member Representative shall promptly provide written instructions to the Escrow Agent, pursuant to the terms of the Nevada Escrow Agreement, to deliver the amount of such unpaid transaction settlement payment to the Members and to the Company for proper payment to the holders of the Company Options as of the Closing pro rata based on the Fully Diluted Units held by such Members or attributable to the Company Options held by such holders of Company Options as of immediately prior to the Closing relative to Total Outstanding Company Units, it being understood that any such payments made to the holders of Company Options shall be subject to Section 3.01(b)(ii)(G). The parties hereto understand and agree that the contingent rights to receive any funds from the Nevada Escrow Account are not transferable, except pursuant to a reorganization, liquidation, or other similar transfer of the assets of the relevant party to its equityholders or a successor entity or by operation of Laws relating to descent and distribution, divorce, and community property.

Each party hereto agrees to, and shall cause its respective Affiliates to, make its respective filing, if necessary, pursuant to the HSR Act with respect to the Transactions as promptly as reasonably practicable after the date hereof and to supply as promptly as practicable to the appropriate Governmental Authorities any additional information and documentary material that may be requested pursuant to the HSR Act. Each party hereto agrees to, and shall cause its respective Affiliates to, make as promptly as practicable its respective filings and notifications, if any, and cooperate with the other parties

(c) Neither party shall, and each party shall cause its Affiliates not to, enter into any transaction, or any agreement to effect any transaction (including any merger or acquisition), that might reasonably be expected to make it more difficult, or to increase the time required, to (i) obtain the expiration or termination of the waiting period under the HSR Act or any other applicable Antitrust Law applicable to the Transactions or (ii) obtain all other authorizations, consents, orders, and approvals of Governmental Authorities necessary for the consummation of the Transactions.

(d) Between the date of this Agreement and the Closing, the Company shall, and shall cause the Related Consolidated Entities to, use commercially reasonable efforts to obtain the consent of one or more third parties to assign the contracts set forth on Section 6.06(d) of the Parent Disclosure Schedule to a professional corporation designated by Parent and any such assignment shall only become effective at the Effective Time.

Parent shall provide the Company with a reasonable opportunity to review and comment on the Registration Statement and the Prospectus, and any amendment or supplement thereto, and any response by Parent to any SEC comments with respect thereto, prior to filing or transmitting such with the SEC, and will promptly provide the Company with a copy of all such filings or transmittals made with the SEC to the extent not available on EDGAR. Parent shall also take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified or filing a general consent to service of process) required to be taken under any applicable state securities Laws in connection with the issuance of Parent Common Stock and the Company shall furnish all information concerning the Company and the holders of Company Common Units as may be reasonably requested in connection with any such action. Parent will advise the Company, promptly after it receives notice thereof, of the time when the Registration Statement has become effective, the issuance of any stop order, the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Registration Statement.

For purposes of this Section 6.09, “participate” means that Parent will be kept reasonably apprised by the Company of proposed strategy and other significant decisions with respect to any member litigation (to the extent the attorney-client privilege between the Company and its counsel is not undermined or otherwise adversely affected), and the Company will make reasonable efforts to allow Parent to observe any deposition or other pre-trial meeting, and Parent may offer comments or suggestions with respect to the litigation but will not be afforded any decision making power or authority over the litigation, except for the right to consent to any settlement as set forth in this Section 6.09.

party such party’s proposed form of Purchase Price Allocation, and (ii) specify in writing those aspects of the form of Purchase Price Allocation proposed by the other party that such party disputes. The parties shall thereafter negotiate in good faith for a further period of fifteen (15) Business Days in order to resolve such disputes.

In connection with the Closing and the transactions contemplated by Section 2.01, and notwithstanding anything in Section 6.01 to the contrary, the Company shall take, or shall cause its Affiliates to take, all actions necessary, in accordance with agreements and instruments reasonably acceptable to Parent, so that (i) prior to the Merger, HCP Blocker Corporation, a Delaware corporation (“Blocker Corporation”), shall either merge with and into the Company with the Company surviving or otherwise be completely liquidated for all applicable tax purposes and cease to exist as a separate entity (the “Liquidation”) and (ii) in connection with the Liquidation, the Class A Units held by Blocker Corporation shall be redeemed, cancelled, or otherwise eliminated by the Company. Following the Closing, the Member Representative shall prepare or cause to be prepared, and shall timely file or cause to be timely filed, any Tax Returns required to be filed by Blocker Corporation, including its final Tax Returns for the year in which the Liquidation occurs (the “Blocker Tax Returns”), to the extent not filed prior to the Closing, and the Member Representative shall also ensure that the Liquidation is properly reflected and reported on such Blocker Tax Returns as a taxable liquidation that occurred in the Pre-Closing Tax Period of the Company; provided that the Member Representative (or, if prior to the Closing, the Company) shall deliver or cause to be delivered a draft of any Blocker Tax Return that is to be filed to Parent no later than thirty (30) days prior to the due date thereof (after giving effect to any extensions for filing), and the Member Representative (or, if prior to the Closing, the Company) shall make such revisions to such Blocker Tax Return as are reasonably requested by Parent; provided, further, that to the extent any such Blocker Tax Return is required to be filed within thirty (30) days after the Closing Date, the Member Representative shall deliver or cause to be delivered a draft of any such Blocker Tax Return to Parent as promptly as practicable following the Closing Date, and in a manner that allows Parent adequate time to sufficiently review such Blocker Tax Return. In addition, in connection with the filing of any Blocker Tax Return to be filed by or on behalf of the Member Representative after the Closing and pursuant to the preceding sentence, and no later than the date on which any such Blocker Tax Return is filed, Parent shall timely pay (or cause one of its Affiliates to timely pay) an amount of cash equal to the portion of the Blocker Tax Liability shown as owing on such Blocker Tax Return on behalf of Blocker Corporation and the Company, and shall coordinate with the Member Representative to ensure that such amount is properly remitted to the appropriate taxing authority on behalf of Blocker Corporation and the Company in connection with the filing of the applicable Blocker Tax Return. For the avoidance of doubt, the payment of Taxes in respect of the Blocker Tax Liability by Parent (or by one of Parent’s Affiliates) on behalf of Blocker Corporation and the Company pursuant to this Section 6.15(h) shall not prevent Parent from seeking indemnity pursuant to Section 8.02(d) in the event that any additional Taxes that are not taken into account for purposes of determining Final Net Working Capital are subsequently owed in respect of the Blocker Tax Liability and in connection with the Liquidation.

(a) The Company shall, and shall cause the Business Entities and Related Consolidated Entities to, cooperate and work with Parent to help Parent identify employees of HCPMGI who provide non-medical services to the Business Entities or Related Entities and whose employment will be transferred to the Surviving Entity, Parent, or any of their Subsidiaries (the “Affected Employees”). Such transfer of the Affected Employees shall occur effective as of the Closing Date, unless Parent gives written notice to the Company at least sixty (60) days prior to the Closing Date that such transfer of Affected Employees shall instead occur as of January 1, 2013 (either such transfer date referred to herein as the “Employee Transfer Date”). With respect to the Affected Employees, the Company shall, and shall cause the Business Entities and Related Consolidated Entities to, assist Parent in its efforts to enter into, or have the Company or any of their Subsidiaries enter into, an offer letter or such other service arrangement as Parent shall deem appropriate with such employee as soon as practicable after the date hereof and in any event prior to the Employee Transfer Date, which offer or arrangement shall be effective immediately following the Employee Transfer Date. Notwithstanding any of the foregoing, none of Parent, the Company, the Surviving Entity, or any of their respective Affiliates shall have any obligation to make an offer of employment or provide such other service arrangement to, or otherwise transfer the employment of, any employee of HCPMGI who solely provides medical services to the Business Entities or Related Entities. Effective immediately following the Employee Transfer Date, the Company shall, and shall cause the Business Entities and Related Consolidated Entities to, take all action necessary to cause HCPMGI to terminate the employment of each of the Affected Employees who has received, but not accepted, an offer of employment or such other service arrangement as Parent shall deem appropriate with Parent, the Company, the Surviving Entity, or any of their Subsidiaries effective immediately following the Employee Transfer Date. Affected Employees who accept offers of employment from, or whose employment will otherwise be transferred to, Parent, the Company, the Surviving Entity, or any of their Subsidiaries shall be referred to herein as “Transferred Employees”. Parent shall promptly reimburse the Business Entities and the Related Consolidated Entities for their reasonable, out-of-pocket costs incurred as a result of complying with this Section 6.16(a) with respect to the Affected Employees, other than any such costs that result from the Business Entities’ or the Related Consolidated Entities’ violation of applicable Law, unless such violation of Law occurred as a result of the Business Entities’ or the Related Consolidated Entities’ compliance with this Section 6.16(a). Any and all expenses arising from or related to any action taken pursuant to this Section 6.16(a) shall be excluded from the calculations of Earn-Out EBITDA. Any and all Liabilities arising from or related to any action taken pursuant to this Section 6.16(a) shall be excluded from the calculations of Indebtedness Amount and Net Working Capital. Any and all cash expended in the compliance with this Section 6.16(a) (net of any reimbursement received by any Business Entity or Related Consolidated Entity from Parent pursuant to this Section 6.16(a)) that would otherwise have reduced Net Working Capital shall be added back to Net Working Capital.

(b) Without limiting any additional rights that current employees of the Business Entities who continue employment with Parent, the Surviving Entity, or any of their Affiliates following the Closing Date (such employees, with the Transferred Employees, referred to herein as “Continuing Employees”) may have under any Plan, from and after the Effective Time and until December 31, 2013, Parent shall cause the Surviving Entity and each of the Related Entities to maintain the severance practices and policies of the Company and the Related Entities that are set forth on Section 6.16(b) of the Company Disclosure Schedule (the “Severance Arrangements”) in accordance with the terms and conditions set forth therein and provide the severance benefits set forth therein to any Continuing Employee whose employment is involuntarily terminated by Parent, the Surviving Entity, or any of their Affiliates following the Effective Time (or following the Employee Transfer Date in the case of Transferred Employees) but on or before December 31, 2013, under circumstances that would otherwise entitle such individual to severance benefits in accordance with the terms and conditions of such Severance Arrangements, provided that the provision of such severance benefits would be consistent with past practice.

(c) From and after the Effective Time (or from and after the Employee Transfer Date in the case of Transferred Employees) and until December 31, 2013, the base salary, target annual bonus opportunity, and target commission opportunity in effect as of immediately prior to the Closing Date shall not be decreased for the Continuing Employees that remain employed during that period.

(d) From and after the Effective Time and until December 31, 2013, with respect to Continuing Employees other than the Transferred Employees, Parent will cause the Surviving Entity (or its Subsidiaries) to maintain for such Continuing Employees each Plan that is an “employee welfare benefit plan” within the meaning of Section 3(1) of ERISA (other than

the Severance Arrangements) and each other Plan that provides vacation, sick, or personal time off (collectively, the “Welfare Plans”) pursuant to its terms in effect immediately prior to the Effective Time, except to the extent any such plan must be amended to comply with applicable Law. Effective as of January 1, 2014, Parent shall, or shall cause the Surviving Entity (or its Subsidiaries) to, either (i) continue the Welfare Plans or adopt new employee welfare plans, programs, or arrangements, (ii) permit such Continuing Employees to participate in the employee welfare plans, programs, or policies (including any severance, vacation, sick, or personal time off plans or programs) of Parent or its Affiliates, or (iii) a combination of clauses (i) or (ii). From and after January 1, 2014, Parent shall, or shall cause its Affiliates to, (y) cause any pre-existing conditions or limitations and eligibility waiting periods under any group health plans of Parent or its Affiliates to be waived with respect to Continuing Employees (other than the Transferred Employees) to the extent such Continuing Employees were not subject to such preexisting conditions and limitations and eligibility waiting periods under the comparable Welfare Plan as of immediately prior to January 1, 2014, and (z) with respect to a Welfare Plan that provides for group health plan benefits and has a plan year that is other than the calendar year, provide each such Continuing Employee with credit for any deductibles or out of pocket expenses paid under such Plan in the plan year in effect as of January 1, 2014, in satisfying any applicable deductible or out of pocket requirements under any group health plans of Parent or its Affiliates that such employees are eligible to participate in as of January 1, 2014, to the same extent that such expenses were recognized under the comparable Welfare Plan.

(e) From and after the Employee Transfer Date and until December 31, 2013, with respect to the Transferred Employees, Parent shall, or shall cause the Surviving Entity (or its Subsidiaries) to, either (i) continue or commence participation in the Welfare Plans or other employee welfare plans, programs, or arrangements of a Related Entity in which such Transferred Employees participated immediately prior to the Effective Time or adopt new employee welfare plans, programs, or arrangements that are substantially identical to or more favorable than such plans, programs, or arrangements (the “New Plans”), (ii) permit such Transferred Employees to participate in the employee welfare plans, programs, or policies (including any severance, vacation, sick, or personal time off plans or programs) of Parent or its Affiliates, or (iii) a combination of clauses (i) or (ii); provided, however, that the benefits provided to the Transferred Employees are substantially identical to or more favorable than the benefits provided to such Transferred Employees pursuant to the Welfare Plans or other employee welfare plans, programs, or arrangements of a Related Entity in which they participated immediately prior to the Effective Time. Effective as of January 1, 2014, Parent shall, or shall cause the Surviving Entity (or its Subsidiaries) to, either (i) continue participation in the Welfare Plans or other employee welfare plans, programs, or arrangements of a Related Entity, continue the New Plans or adopt new employee welfare plans, programs, or arrangements, (ii) permit the Transferred Employees to participate in the employee welfare plans, programs, or policies (including any severance, vacation, sick, or personal time off plans or programs) of Parent or its Affiliates, or (iii) a combination of clauses (i) or (ii). From and after the Employee Transfer Date, Parent shall, or shall cause its Affiliates to, (i) cause any pre-existing conditions or limitations and eligibility waiting periods under any New Plan or the group health plans of Parent or its Affiliates in which a Transferred Employee will participate to be waived with respect to such Transferred Employee to the extent such Transferred Employee was not subject to such preexisting conditions and limitations and eligibility waiting periods under the comparable employee welfare plans, programs, or arrangements of the Surviving Entity or a

Related Entity in which such Transferred Employee participated as of immediately prior to the date the Transferred Employee’s participation will commence under any New Plan or the group health plans of Parent or its Affiliates, as applicable, and (ii) provide each Transferred Employee with credit for any deductibles or out of pocket expenses paid under such employee welfare plans, programs, or arrangements of the Surviving Entity or a Related Entity in which such Transferred Employee participated as of immediately prior to the date the Transferred Employee’s participation will commence under any New Plan or the group health plans of Parent or its Affiliates, as applicable, in the plan year in effect as of such date in satisfying any applicable deductible or out of pocket requirements under any New Plan or group health plans of Parent or its Affiliates that such employee is eligible to participate in to the same extent that such expenses were recognized under the comparable employee welfare plans, programs, or arrangements of the Surviving Entity or a Related Entity.

(f) From and after the Effective Time and until December 31, 2013, Parent shall, or shall cause the Surviving Entity or its Subsidiaries to, maintain, or as applicable commence or continue participation in, each Plan intended to include a Code Section 401(k) arrangement pursuant to its terms in effect immediately prior to the Effective Time, except to the extent any such plan must be amended to comply with applicable Law.

(g) From and after the Employee Transfer Date and until December 31, 2013, with respect to the Transferred Employees, Parent shall, or shall cause the Surviving Entity (or its Subsidiaries) to adopt a new nonqualified deferred compensation plan; provided, however, that the benefits provided to each Transferred Employee who elects to participate in such deferred compensation plan are no less favorable in the aggregate than the benefits provided to such Transferred Employees pursuant to the Deferred Compensation Plan or Deferred Compensation Plan 2 of HCPMGI in which the Transferred Employee participated immediately prior to the Effective Time. It is the intent of the parties that in the event any Transferred Employee is paid a distribution or commences receipt of distributions pursuant to the Deferred Compensation Plan or Deferred Compensation Plan 2 of HCPMGI as a result of his or her termination of employment from HCPMGI in connection with the Closing, Parent shall, or shall cause the Surviving Entity (or its Subsidiaries) to, pay to the Transferred Employee an amount in cash to make the Transferred Employee whole for the income taxes payable with respect to any such distributions (the “DC Distribution Tax Payment”), as well as any income and employment taxes payable on the DC Distribution Tax Payment (the “Income Tax Payment” and together with the DC Distribution Tax Payment, the “Deferred Compensation Tax Payment”) such that the Transferred Employee is in no worse position than if no distribution from the Deferred Compensation Plan or Deferred Compensation Plan 2 had occurred. With respect to a Transferred Employee who has elected or is required to receive a lump sum distribution, the Deferred Compensation Tax Payment shall be paid within fifteen (15) Business Days of the distribution. Following the date of this Agreement, the Company and Parent shall work together in good faith to determine (i) whether any distributions from the Deferred Compensation Plan or Deferred Compensation Plan 2 of HCPMGI are scheduled to be made to individuals who are anticipated to be Transferred Employees in the form of either a lump sum or installments and (ii) when the Deferred Compensation Tax Payment will be made to eligible Transferred Employees who have elected distributions in the form of installment payments. Notwithstanding any provision in this Agreement to the contrary, (i) Parent shall be solely liable and responsible for all Liabilities arising from or related to, the Deferred Compensation Tax Payment and in no event shall any Member be deemed, pursuant to Section 8.02, to have indemnified any Parent Indemnified Party for any Losses arising from or related to Deferred Compensation Tax Payment and (ii) (x) any and all expenses arising from or related to the Deferred Compensation Tax Payment shall be excluded from the calculations of Earn-Out EBITDA, (y) any and all Liabilities arising from or related to the Deferred Compensation Tax Payment shall be excluded from the calculations of Indebtedness Amount and Net Working Capital, and (z) any and all cash expended in making the Deferred Compensation Tax Payment that would otherwise have reduced Net Working Capital shall be added back to Net Working Capital.

(h) As of the date Continuing Employees are eligible to participate in the employee benefit plans, programs, or policies of Parent or its Affiliates (the “Parent Plans”), Parent will, or will cause the Surviving Entity to, give Continuing Employees full credit under such Parent Plans for purposes of eligibility, vesting and determination of level of benefits (but not to the extent that such credit would result in duplication of benefits) for the Continuing Employees’ service with the Business Entities and Related Entities and their predecessor entities to the same extent recognized by the Company, the Business Entities, and the Related Entities immediately prior to the Effective Time under an analogous Plan.

(i) Parent shall cause the Surviving Entity and each of the Parent Subsidiaries, for a period commencing at the Effective Time and ending ninety (90) days thereafter, not to effectuate a “plant closing” or “mass layoff” as those terms are defined in the Worker Adjustment and Retraining Notification Act of 1988 (together with any similar state or local Law, “WARN”) without complying with all provisions of WARN or any similar provision of applicable foreign Law. Notwithstanding any provision in this Agreement to the contrary, in the event Parent terminates, or requests or causes the termination of, the employment of any employee of any Business Entity or Related Entity with such Business Entity or Related Entity on or following the Closing (whether or not such employee is thereafter promptly employed by any Business Entity or Related Entity), (i) Parent shall be solely liable and responsible for compliance with, and for all Liabilities arising from or related to, such termination under WARN and any similar state or local law or ordinance and in no event shall any Member be deemed, pursuant to Section 8.02, to have indemnified any Parent Indemnified Party for any Losses arising from or related to any such termination and (ii) (x) any and all expenses arising from or related to any such termination under WARN and any similar state or local law or ordinance shall be excluded from the calculations of Earn-Out EBITDA, and (y) any and all Liabilities arising from or related to any such termination under WARN and any similar state or local law or ordinance shall be excluded from the calculations of Indebtedness Amount and Net Working Capital.

(j) No provision of this Section 6.16 or any other provision of this Agreement, express or implied: (i) shall be construed to establish, amend, or modify any Plan, any benefit plan, program, agreement, or arrangement or the terms of any sub agreements or sub plans, terms and conditions, restrictive covenants, or participation requirements thereof, except and to the extent such amendment is explicitly contemplated by the express language of this Agreement; (ii) shall, following the second anniversary of the Effective Time, limit the ability of Parent or any of its Affiliates (including, following the Effective Time, the Surviving Entity and any of its Subsidiaries) to amend, modify, or terminate any benefit plan, program, agreement, or arrangement at any time assumed, established, sponsored, or maintained by any of them; (iii) is intended to confer upon any current or former employee (including any Continuing Employee) or any other Person any right to employment or continued employment for any period of time by reason of this Agreement, or any right to a particular term or condition of employment; or (iv) is intended to confer upon any Continuing Employee any rights or remedies under this Section 6.16, including the right to enforce any obligations of Parent or the Surviving Entity contained in this Section 6.16 as a third party beneficiary.

Section 6.17. Section 16 Matters. Prior to the Effective Time, each of the Company and Parent shall take all such steps as may be required (to the extent permitted under applicable Law) to cause any dispositions of Company Common Units or acquisitions of Parent Common Stock (including, in each case, derivative securities) resulting from the Transactions by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

(a) It is the intent of the parties hereto that the aggregate magnitude of the long-term incentive awards described in this Section 6.18, whether in stock-based or cash-based form, shall result in aggregate compensation expense (excluding any compensation expense attributable to any stock-based or cash-based awards granted to Robert Margolis, M.D.) of approximately $40,000,000, to be expensed over the applicable vesting period(s).

(b) If Parent provides written notice no later than ten (10) Business Days prior to the Closing Date, the Company shall grant Stock-Based Awards under the Company Plan to the groups of Continuing Employees and in the amounts and subject to the terms and conditions to be set forth on a schedule to be mutually agreed upon in good faith between Parent and the Company’s CEO as soon as administratively practicable following the date of this Agreement, provided that such Stock-Based Awards shall be effective as of immediately prior to, but contingent upon, the Effective Time. The number of Company Common Units subject to each such Stock-Based Award shall be determined by dividing (1) the quotient obtained by dividing the dollar amount set forth for the recipient on the schedule described in this Section 6.18(b) by an amount equal to the product of the One Day Parent Stock Volume-Weighted Average Price as of the date of grant and 52.0875% by (2) the Exchange Ratio. If applicable, the per unit base or exercise price of such award shall be determined by multiplying the closing price of Parent Common Stock on the New York Stock Exchange on the Closing Date by the Exchange Ratio. Each Stock-Based Award will be subject to the terms, definitions and provisions of the Company Plan, with such amendments as Parent shall deem necessary or appropriate and which will be effective solely with respect to the Stock-Based Awards, and an applicable form of award agreement to be provided by Parent. Parent will consult in good faith with the Company’s CEO but will make the final determination in its discretion as to the amendments that Parent deems necessary or appropriate for the Company Plan and the intended assumption by Parent of any Stock-Based Awards, provided that such amendments shall not adversely effect the intended economic benefits to be granted to Continuing Employees pursuant to this Section 6.18(b). Prior to the Effective Time, and subject to the advance review and approval of Parent, which shall not be unreasonably withheld, conditioned or delayed, the Company shall have taken all actions necessary to effect the grant of any Stock-Based Awards directed by Parent to be made, including delivering all required notices, adopting appropriate forms of award agreement for the Stock-Based Award (which shall provide, among other things, for a vesting commencement date of no earlier than the Effective Time, for no accelerated vesting as a result of the Merger, and

that such Stock-Based Awards shall terminate in the event this Agreement is terminated pursuant to ARTICLE IX hereof), authorizing the granting of the type(s) of Stock-Based Awards contemplated in this Section 6.18(b), and obtaining any required consents and/or approvals necessary to effectuate the provisions of this Section 6.18(b) and which may otherwise be required pursuant to applicable Law.

(c) Notwithstanding anything herein to the contrary, if Parent obtains a recommendation by ISS of a vote “for” the amendment to its 2011 Incentive Award Plan described in Parent’s Proxy Statement for its 2012 Annual Stockholder Meeting, Parent shall not direct the Company to grant, and the Company shall not grant, any Stock-Based Awards.

(d) As soon as practicable, but in no event later than twenty-one (21) days after the Closing Date, Parent agrees to grant cash-settled performance-based long-term incentive plan awards to the groups of Continuing Employees and in the amounts and subject to the terms and conditions to be set forth on a schedule to be mutually agreed upon by Parent and the Company’s CEO as soon as administratively practicable following the date of this Agreement. In addition, in the event that no Stock-Based Awards will be granted in accordance with Section 6.18(b), within twenty-one (21) days after the Closing Date, Parent agrees to grant stock-based awards to the groups of Continuing Employees and in the amounts and subject to the terms and conditions to be set forth on a schedule to be mutually agreed upon by Parent and the Company’s CEO as soon as administratively practicable following the date of this Agreement. The number of shares of Parent Common Stock subject to each such stock-based award shall be determined by dividing the dollar amount set forth for the recipient on the schedule described in this Section 6.18(d) by an amount equal to the product of the One Day Parent Stock Volume-Weighted Average Price as of the date of grant and 52.0875%. If applicable, the per unit base or exercise price of such award shall be determined by the closing price of Parent Common Stock on the New York Stock Exchange on the date of grant. Finally, with respect to the portion of the approximately $40,000,000 of long-term incentive compensation expense referenced in Section 6.18(a) above that remains after any grants of long-term incentive awards are made either immediately prior to Closing in accordance with Section 6.18(b) or within twenty-one (21) days following the Closing Date in accordance with this Section 6.18(d), as soon as practicable, but in no event later than five (5) Business Days after the one year anniversary of the Closing Date, Parent agrees to grant stock-based awards to the groups of Continuing Employees and in the amounts and subject to the terms and conditions to be set forth on a schedule to be mutually agreed upon by Parent and the Company’s CEO as soon as administratively practicable following the date of this Agreement.

(e) It is the intent of the parties that any long-term incentive awards for any new employees of Parent, the Surviving Entity, or any of their Affiliates will be mutually agreed upon in good faith between Parent and the Company’s CEO, consistent with appropriate corporate governance, including Parent’s corporate policy on long-term incentive compensation. Parent’s CEO and the Parent Board shall retain ultimate decision-making authority as it relates to the corporate policy on long-term incentive compensation. Notwithstanding the above, to the extent Parent recommends taking or opposing any action or decision with respect to any long-term incentive awards for a new employee of Parent, the Surviving Entity, or any of their Affiliates and the Company’s CEO is opposed to such Parent recommendation or decision, the Company’s CEO has the right to request that the Parent Board decide the issue, in which case the

matter shall be determined by the Parent Board (and no such taking or opposing such action or decision shall be acted upon until such time as the Parent Board approves such taking or opposing such action or decision after considering in good faith the objections of the CEO).

Section 6.19. Earn-Out EBITDA LTIP. In the event that the Earn-Out EBITDA for the fiscal year ended December 31, 2013 is equal to or greater than $600,000,000 or payment of the Second Tranche is accelerated pursuant to Section 3.06(e), then Parent shall, no later than the first date of payment of the Second Tranche (including as such payment may be accelerated pursuant to Section 3.06(e)), grant cash-settled performance-based long-term incentive plan awards, totaling $20,000,000 in the aggregate, to the groups of individuals and in the amounts and subject to the terms and conditions to be set forth on a schedule to be mutually agreed upon by Parent and the Company’s CEO.

Section 6.20. AMG Documents. Notwithstanding any other provision in this Agreement to the contrary, each of the parties hereto acknowledges and agrees that (i) the transactions contemplated by the AMG Documents shall not be effected or be otherwise deemed to have been consummated, or otherwise have any effect on the Business Entities or the Related Entities, prior to the Closing and (ii) Earn-Out EBITDA, EBITDA, Indebtedness, Indebtedness Amount, and Net Working Capital shall be calculated as though the transactions contemplated by the AMG Documents had never been agreed to or consummated. The parties hereto acknowledge and agree that the amount of the capital contribution made by Seismic Medical Group, PC, a California professional corporation, to HCPAMG in exchange for an interest therein pursuant to Amendment No. 5 to the Second Amended and Restated Partnership Agreement of HCPAMG corresponds to their understanding of the fair market value of such interest and the aggregate net fair market value of the assets and liabilities of HCPAMG.

The representations and warranties of the parties hereto contained in this Agreement and the EQ Representations shall survive the Closing until the date that is the second (2nd) anniversary of the Closing Date (the “Survival End Date”), except for (i) the representations and warranties set forth in Section 4.01 (Organization, Authority and Qualification of the Company), Section 4.02 (Organization, Authority and Qualification of the Business Entities and Related Entities), Section 4.03(b) (Ownership of Equity Interests), Section 4.03(c) (No Options), Section 4.28 (Brokers), Section

The covenants and agreements contained in this Agreement (other than covenants and agreements to be performed after the Closing) shall expire on the Effective Time, and each covenant and agreement contained in this Agreement to be performed after the Closing shall expire immediately following one hundred twenty (120) days after the date on which such covenant or agreement is to be performed; provided, however, that any claim made in accordance with Section 8.05 by the party seeking to be indemnified within the time periods set forth in this Section 8.01 shall survive until such claim is finally and fully resolved. Following the expiration of a representation, warranty, covenant, or agreement, no Action may be initiated by any Parent Indemnified Party or Company Indemnified Party (as hereinafter defined) with respect thereto, regardless of any statute of limitations period that would otherwise apply.

Section 8.02. Indemnification by the Members. Parent and its Affiliates (including the Business Entities following the Closing) and their respective officers, directors, employees, and agents (each, a “Parent Indemnified Party”) shall from and after the Closing be indemnified and held harmless by the Members, jointly and severally, from and against all Liabilities, claims, damages (but excluding for all purposes under this ARTICLE VIII any consequential, incidental, or indirect damages, mental or emotional distress, diminution in value, lost profits, special, punitive, exemplary, or similar damages, and any damages calculated as a multiple of earnings, EBITDA, or revenue or loss of business reputation or opportunity), interest, awards, judgments, penalties, expenses, and assessments (in each case, including reasonable attorneys’ and consultants’ fees and expenses) (collectively, “Losses”) suffered or incurred by them arising out of or resulting from (without duplication):

(a) any misrepresentation in or breach of any of the representations or warranties of the Company contained in ARTICLE IV of this Agreement (other than the representations and warranties contained in Section 4.21, which are addressed in Section 8.02(d)) or any of the EQ Representations;

(b) the breach of, or failure to perform, any covenant or agreement of the Company (but only to the extent that any such covenant or agreement is to be performed by the Company prior to the Closing), the Members, or the Member Representative contained in this Agreement (other than the covenants and agreements set forth in Section 6.01(b)(xix) and Section 6.15, which are addressed in Section 8.02(d));

(c) any Losses, including any adverse impact on management fees to be paid to any Business Entity after the Closing pursuant to one or more management agreements with Related Entities, attributable to both (x) the operation of the Business on or prior to December 31, 2012 (as measured by date of service occurring on or prior to December 31, 2012) and (y) either of the following:

(i) any net negative adjustments (netting out all positive adjustments, including recoupments, against all negative adjustments) made to, or net repayments (netting out all positive adjustments, including recoupments, against all negative adjustments) of, pre- or post-Closing capitation or other payments from Payors to any of the Related Entities as a result of an adjustment of or challenge to the applicable plan’s risk adjustment factors by CMS or as a result of any withdrawal or nonvalidation of codes submitted by any of the Related Entities, in each case pursuant to a risk adjustment data validation audit (or other similar or successor audit(s)) of pre-Closing activity by CMS or its contractors; or

(ii) any disclosure (including self-disclosures) to, or investigation, action, order, or audit by, CMS, any other Governmental Authority regulating or enforcing Health Care Laws or Payor, or any agent or contractor thereof or thereto, with respect to pre-Closing activity, including a disclosure by a whistleblower with respect to any Business Entity or Related Entity, in all cases computed net of all positive adjustments, including recoupments, resulting from all such disclosures, investigations, actions, orders or audits;

provided, however, that any indemnification obligation of the Members under this Section 8.02(c) that is attributable to the operation of the Business (as measured by date of service) during the period from the Closing Date until December 31, 2012, shall be prorated by multiplying the amount of such Losses by a fraction, the numerator of which is the number of days in 2012 through the Closing Date and the denominator of which is 366; it further being agreed, for the sake of clarity, that there shall be no proration or reduction for any Losses attributable to the operation of the Business (as measured by date of service) prior to the Closing Date and that the Members shall be responsible hereunder, pursuant to the terms and conditions of this Section 8.02(c), for all such pre-Closing Date Losses; and

(d) Indemnified Taxes (and for purposes of this Section 8.02(d), Losses shall include Taxes).

Section 8.03. Indemnification by Parent. The Members and their respective officers, managers, equityholders, employees, and agents (each, a “Company Indemnified Party”) shall from and after the Closing be indemnified and held harmless by Parent from and against any and all Losses suffered or incurred by them arising out of or resulting from (without duplication):

(a) any misrepresentation in or breach of any of the representations or warranties of Parent or Merger Sub contained in ARTICLE V of this Agreement;

(c) any Taxes imposed on the Business Entities or the Related Entities, or any Taxes that are imposed on any Member with respect to a Pre-Closing Tax Period as a result of

the breach of, or failure to perform, any covenant or agreement herein by Parent or any Affiliate of Parent, including, after the Closing, the Company or any Affiliate of the Company, and that are not Indemnified Taxes subject to indemnification pursuant to Section 8.02(d) (and for purposes of this Section 8.03(c), Losses shall include Taxes); and

(d) the execution of the AMG Documents and the transactions contemplated thereby (and for purposes of this Section 8.03(d), Losses shall include Taxes other than Taxes resulting from a negative tax capital account maintained by a partner of HCPAMG).

Section 8.04. Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement:

(a) (i) The Members shall not be liable for any Losses pursuant to Section 8.02(a) (other than Section 4.21 (Taxes)) or Section 8.02(c) unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Members exceeds $27,500,000, whereupon the Parent Indemnified Party shall be entitled to indemnification for the full amount of such Losses (without deduction of such threshold amount); (ii) no claim for indemnification by any Parent Indemnified Party pursuant to Section 8.02 shall be asserted for any individual item or a series of related items where the Losses with respect to such item or series of related items are less than $100,000 (and if the Losses relating to such item or series of related items do not exceed $100,000, then no such Losses shall be counted toward satisfaction of the threshold set forth in Section 8.04(a)(i)); (iii) the maximum aggregate amount of indemnifiable Losses which may be recovered from the Members shall be an amount equal to the value, if any, of Parent Common Stock and the amount, if any, of cash remaining in the Escrow Fund on or prior to the Survival End Date and in the Healthcare Indemnity Account and the Tax Indemnity Account following the Survival End Date (the “Cap”) (it being understood that the Members shall not be liable for Losses in the aggregate in excess of the Cap); (iv) following the Survival End Date, the only indemnifiable Losses which may be recovered from the Members (and any such recovery shall be limited by the Cap) shall be (A) from the Healthcare Indemnity Account but only until the Fourth Escrow Distribution Date (except as otherwise provided in Section 8.04(a)(v)) and only (x) pursuant to Section 8.02(a) but only with respect to the representations and warranties set forth in Section 4.15 (Healthcare Regulatory Compliance) and (y) pursuant to Section 8.02(c), and (B) from the Tax Indemnity Account but only until the Fifth Escrow Distribution Date (except as otherwise provided in Section 8.04(a)(vi)) and only pursuant to Section 8.02(d); (v) following the Fourth Escrow Distribution Date, the only indemnifiable Losses which may be recovered from the Healthcare Indemnity Account shall be for any claim made by a Parent Indemnified Party on or prior to the Fourth Escrow Distribution Date in accordance with Section 8.05 and of the type described in Section 8.04(a)(iv)(A)(x) or Section 8.04(a)(iv)(A)(y), in each case that remains unresolved as of the Fourth Escrow Distribution Date; (vi) following the Fifth Escrow Distribution Date, the only indemnifiable Losses which may be recovered from the Tax Indemnity Account shall be for any claim made by a Parent Indemnified Party on or prior to the Fifth Escrow Distribution Date in accordance with Section 8.05 and of the type described in Section 8.04(a)(iv)(B), in each case that remains unresolved as of the Fifth Escrow Distribution Date; (vii) the Members shall not be liable for any Losses for Indemnified Taxes under Section 8.02(d) to the extent arising out of, resulting from, or accelerated by, the breach of any covenant herein by Parent or any Affiliate of Parent,

including, after the Closing, the Company or any Affiliate of the Company, and (viii) the Members shall not be liable for any Losses to the extent arising out of or resulting from the execution of the AMG Documents or the transactions contemplated thereby (it being understood that, for the avoidance of doubt, this clause (viii) shall not require Parent to indemnify any Member that is also a partner of HCPAMG for Taxes resulting from a negative tax capital account maintained by such partner in HCPAMG, as provided in Section 8.03(d) above); provided, however, that the limitations set forth in this Section 8.04(a) shall not apply in respect of any indemnification obligation arising out of or resulting from fraud or intentional misrepresentation by the Company (to the extent occurring prior to the Closing) or any Member (it being understood that any such indemnification obligation may only be recovered from the Escrow Fund if a claim is made with respect thereto on or prior to the Survival End Date in accordance with Section 8.05 and may not be recovered from the Healthcare Indemnity Account or the Tax Indemnity Account) and provided, further, that the limitations set forth in clause (i) of this Section 8.04(a) shall not apply to breaches by the Company of any of the Specified Reps.

(b) (i) Parent shall not be liable for any Losses pursuant to Section 8.03(a) unless and until the aggregate amount of indemnifiable Losses which may be recovered from Parent exceeds $5,008,380, whereupon the Company Indemnified Party shall be entitled to indemnification for the full amount of such Losses (without deduction of such threshold amount); (ii) no claim for indemnification by any Company Indemnified Party pursuant to Section 8.03(a) or Section 8.03(b) shall be asserted for any individual item or a series of related items where the Losses with respect to such item or series of related items are less than $100,000 (and if the Losses relating to such item or series of related items do not exceed $100,000, then no such Losses shall be counted toward satisfaction of the threshold set forth in Section 8.04(b)(i)); (iii) the maximum aggregate amount of indemnifiable Losses which may be recovered from Parent under Section 8.03(a) and Section 8.03(c) shall be an amount equal to $101,875,000 (it being understood that Parent shall not be liable for Losses in the aggregate in excess of $101,875,000 pursuant to this clause (iii)); and (iv) Parent shall not be liable for any Losses pursuant to Section 8.03(c) or Section 8.03(d) to the extent arising out of, resulting from, or accelerated by, the breach of any covenant herein by any Member or, prior to the Closing, by the Company or any Affiliate of the Company; provided, however, that the limitations set forth in this Section 8.04(b) shall not apply in respect of any indemnification obligation arising out of or resulting from fraud or intentional misrepresentation by Parent or Merger Sub, or by the Company (to the extent occurring after the Closing), and provided, further, that the limitations set forth in clause (i) of this Section 8.04(b) shall not apply to breaches by Parent or Merger Sub of any of the Specified Reps.

(c) The Members’ liability for any Losses shall be satisfied solely and exclusively from the Escrowed Merger Consideration then held by the Escrow Agent in the Escrow Account on or prior to the Survival End Date (the “Escrow Fund”) or in the Healthcare Indemnity Account and in the Tax Indemnity Account after the Survival End Date by reducing the amounts that would otherwise become payable to the Members under the Escrow Agreement, and in no event shall any such Losses other than from Escrowed Merger Consideration in the Escrow Account, the Healthcare Indemnity Account and the Tax Indemnity Account be payable by the Members through application of Section 10.10. Notwithstanding anything else herein to the contrary, the parties hereby acknowledge and agree that once Escrowed Merger Consideration in the Escrow Account, the Healthcare Indemnity Account and the Tax Indemnity

Account has been exhausted or fully paid to the Members and the holders of Company Options, the only liability of the Members for Losses hereunder that shall survive shall be with respect to breaches of any of the Specified Reps arising out of or resulting from fraud or intentional misrepresentation by the Company (to the extent occurring prior to the Closing) or any Member, which liability shall be several and not joint among the Members and shall be allocated pro rata based on the Fully Diluted Units held by such Members as of immediately prior to the Closing relative to Total Outstanding Company Units.

(d) For all purposes of this ARTICLE VIII, the representations and warranties of the Company shall not be deemed to be qualified by any references to the terms “material”, “materially”, “Material Adverse Effect” or terms of similar meaning; provided, however, that, in no event shall (A) “Material Contract” be read to mean “Contract” or (B) any such “material”, “materially” or “Material Adverse Effect” be read out of Section 4.12 or Section 4.22(a). For all purposes of this ARTICLE VIII, “Losses” shall be net of (A) any insurance proceeds actually paid to the Indemnified Party or any of its Affiliates in connection with the facts giving rise to the right of indemnification and, if the Indemnified Party or any of its Affiliates receives such proceeds after receipt of payment from the Indemnifying Party, then the amount of such proceeds, net of any related deductibles and reasonable expenses incurred in obtaining them, shall be paid to the Indemnifying Party; (B) any prior or subsequent contribution or other payments or recoveries of a like nature by the Indemnified Party from any third Person (other than the Indemnifying Party) with respect to such Losses; and (C) any amount reserved on the Estimated Closing Balance Sheet or, on and after such time there exists a balance sheet from which Final Net Working Capital and Final Indebtedness Amount are calculated, such balance sheet with respect to such Loss to the extent that such amount was included in Final Net Working Capital or Final Indebtedness Amount. Each of the parties hereto acknowledges and agrees to treat any payment for any indemnification claim pursuant to this Agreement as an adjustment to the consideration received hereunder by the applicable holder of Company Common Units for such Company Common Units or by the applicable holder of Company Options for such Company Options. Each Indemnified Party shall be obligated to use its commercially reasonable efforts to mitigate all Losses after it becomes aware of any event that could reasonably be expected to give rise to any Losses that are indemnifiable or recoverable hereunder or in connection herewith.

(e) (i) No Indemnifying Party shall be liable for any Losses in respect of any liability or Loss that is contingent unless and until such contingent liability or Loss becomes an actual liability or Loss and is due and payable and (ii) no Indemnifying Party shall be liable to pay any amount in discharge of a claim under this ARTICLE VIII unless and until the Liability or Loss in respect of which the claim is made has become due and payable.

(f) An Indemnified Party shall not be entitled under this Agreement to multiple recoveries for the same Loss.

(g) No Parent Indemnified Party shall be entitled to indemnification under this ARTICLE VIII with respect to any Losses to the extent that such Losses have been incorporated into the final determination of the “Final Net Working Capital” or the “Final Indebtedness Amount” pursuant to Section 3.05 and Parent has been paid the Total Shortfall Amount, if any, to which it is entitled pursuant to such Section.

(h) The right of a Parent Indemnified Party or a Company Indemnified Party to indemnification or to assert or recover on any claim shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy of or compliance with any of the representations, warranties, covenants, or agreements set forth in this Agreement. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or agreement, shall not affect the right to indemnification or other remedy based on such representations, warranties, covenants or agreements.

(i) Parent may offset any amounts to which it may be entitled under the terms of this Agreement against amounts otherwise payable by it under this Agreement. Neither the exercise of, nor the failure to exercise, such right of offset shall constitute an election of remedies or limit Parent in any manner in the enforcement of any other remedies that may be available to it hereby.

(j) Any Loss incurred by a Parent Indemnified Party to the extent due to its or the Company’s or a Related Consolidated Entity’s direct or indirect ownership of equity securities of a less than wholly owned Related Entity shall be limited to the Losses attributable to such Parent Indemnified Party’s or the Company’s or such Related Consolidated Entity’s ownership interest and shall not include any Losses incurred to the extent due to any other ownership interest of equity securities in such Related Entity.

(a) An Indemnified Party shall give the Indemnifying Party written notice of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within forty-five (45) days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this ARTICLE VIII except to the extent that the Indemnifying Party is materially prejudiced by such failure.

(b) If an Indemnified Party shall receive notice of any Action, audit, claim, demand, or assessment against it (each, a “Third-Party Claim”) that may give rise to a claim for Loss under this ARTICLE VIII, within thirty (30) days of the receipt of such notice (or within such shorter period as may be required to permit the Indemnifying Party to respond to any such claim), the Indemnified Party shall give the Indemnifying Party written notice of such Third-Party Claim together with copies of all notices and documents served on or received by the Indemnified Party; provided, however, that the failure to provide such notice or copies shall not release the Indemnifying Party from any of its obligations under this ARTICLE VIII except to the extent that the Indemnifying Party is materially prejudiced by such failure. The Indemnifying Party shall be entitled to assume and control the defense of such Third-Party Claim at its expense and through counsel of its choice (provided that such counsel is not reasonably objected to by the Indemnified Party) if it gives notice of its intention to do so to the Indemnified Party within thirty (30) days of the receipt of such notice from the Indemnified Party; provided that, if the

Third-Party Claim consists of an Action brought against or with respect to the Indemnified Party by a Governmental Authority enforcing, or asserting Losses as a result of a violation of, Health Care Laws, the Indemnified Party shall be entitled, by giving written notice to the Indemnifying Party concurrently with the giving of written notice of such Third-Party Claim, to elect to jointly assume and control the defense of such Third-Party Claim with the Indemnifying Party, with each of the Indemnified Party and Indemnifying Party bearing one-half of the expense of such defense and through counsel jointly selected by the Indemnified Party and the Indemnifying Party. If the Indemnifying Party elects to undertake any such defense (other than a joint defense as described above) against a Third-Party Claim, the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall reasonably cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense (other than in the case of a joint defense as described above where such expense shall be split equally), all witnesses, pertinent records, materials, and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto (or in the possession or control of any of its Affiliates or its or their Representatives) as is reasonably requested by the Indemnifying Party or its counsel. If the Indemnifying Party elects to direct the defense of any Third-Party Claim pursuant to this Section 8.05, the Indemnified Party shall not pay or approve the payment of any part of such Third-Party Claim unless the Indemnifying Party consents in writing to such payment or unless the Indemnifying Party withdraws from the defense of such Third-Party Claim or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Party is entered against the Indemnified Party for such Third-Party Claim. If the Indemnifying Party has elected to direct and is directing the defense of any Third-Party Claim pursuant to this Section 8.05, the Indemnified Party shall not forgo any appeal or admit any Liability with respect to, or settle, compromise, or discharge, such Third-Party Claim without the Indemnifying Party’s prior written consent. The Indemnifying Party shall have the right to settle any Third-Party Claim for which it obtains a full release of the Indemnified Party in respect of such Third-Party Claim (and which settlement does not impose injunctive or other equitable relief against the Indemnified Party or a finding or admission of any violation of applicable Law or violation of the rights of any Person by the Indemnified Party) or to which settlement the Indemnified Party consents in writing, such consent not to be unreasonably withheld, conditioned, or delayed.

Section 8.06. Remedies. Each of the parties hereto acknowledges and agrees that following the Closing, other than as provided in Section 10.10 (but subject to Section 8.04(c)), (i) the indemnification provisions of this ARTICLE VIII and Section 6.08(c) shall be the sole and exclusive remedies of the parties hereto for any breach of the representations and warranties contained in this Agreement or of the EQ Representations and for any failure to perform or comply with any covenant or agreement in this Agreement; and (ii) any and all claims arising out of or in connection with the Transactions must be brought under and in accordance with the terms of this Agreement. In furtherance of the foregoing, each party hereto hereby waives, from and after the Closing, to the fullest extent permitted by Law, any and all other rights, claims, and causes of action it may have against the other party or its Affiliates, successors, and permitted assigns relating to the subject matter of this Agreement (other than claims for fraud or intentional misrepresentation).

Section 8.07. Subrogation. Upon making any payment to the Indemnified Party for any indemnification claim pursuant to this ARTICLE VIII, the Indemnifying Party shall be subrogated, to the extent of such payment, to any rights which the Indemnified Party may have against any third-parties with respect to the subject matter underlying such indemnification claim and the Indemnified Party shall assign any such rights to the Indemnifying Party.

(a) Each Member shall be deemed to have irrevocably approved the designation of, and hereby irrevocably designates, Robert D. Mosher as the Member Representative and Robert D. Mosher is hereby appointed as of the date hereof as the true and lawful agent and attorney in fact of the Members as the Member Representative for and on behalf of the Members to give and receive notices and communications in connection with this Agreement and related matters, including in connection with claims for indemnification under this ARTICLE VIII, to take all actions, including the payment of expenses or defense on behalf of Members pursuant to Section 8.05, and to agree to, negotiate, defend, and enter into settlements, adjustments, and compromises of, and commence and prosecute litigation and comply with Governmental Orders with respect to, such claims, and to take all other actions, including the giving of instructions to the Escrow Agent, that are either (i) necessary or appropriate in the judgment of the Member Representative for the accomplishment of the foregoing or (ii) specifically authorized or mandated by Section 3.02, Section 3.05, Section 3.06, Section 3.07, Section 3.08, Section 6.15, Section 7.01, Section 7.02, and Section 8.08 and ARTICLE X. In fulfilling his duties hereunder, the Member Representative shall act in good faith and in a manner that the Member Representative reasonably believes to be in the best interests of the Members, taken as a whole, and consistent with his obligations under this Agreement. The Member Representative shall be assisted from time to time by such Persons as the Member Representative deems necessary and appropriate in exercising his duties under this Agreement. The Member Representative shall be subject to removal by the Majority Member (or its designated successor). If the Member Representative shall die, be removed, become disabled or resign, or the Member Representative is otherwise unable to fulfill his responsibilities hereunder, the Majority Member shall appoint a successor Member Representative as soon as reasonably practicable after such death, removal, disability, resignation, or inability, and immediately thereafter notify Parent of the identity of such successor. Any such successor shall succeed the former Member Representative as the Member Representative hereunder. Notices or communications to or from the Member Representative shall constitute notice to or from the Members. Each Member hereby agrees to receive correspondence from the Member Representative, including in electronic form. As promptly as reasonably practicable following the date hereof, the Company shall deliver to the Member Representative a mailing list with the mailing address and email address of each Member and holder of Company Options and the Member Representative may rely on such mailing list unless notified in writing by any Member, holder of Company Options, or any authorized representative of any Member or holder of Company Options of a change in such Member’s or holder of Company Options’ mailing address or email address or of a transfer pursuant to Section 3.07, indentifying (in the case of a transfer) the name and address of the successor interest holder. It is understood by all parties that Robert D. Mosher is executing this Agreement solely in his capacity as the Member Representative and solely with respect to the specified provisions of this Agreement specified in the first sentence of this clause (a), and the Member Representative shall have no duties or obligations, at law, in equity, by contract, or otherwise, to act on behalf of any Member, except for those duties or obligations expressly set forth in this Agreement.

(b) Any and all costs and expenses of the Member Representative, including any costs and expenses of any Person retained by the Member Representative to provide assistance, counsel, or other advisory services, incurred in performing his obligations under this Agreement shall be paid or recovered from funds in the MR Escrow Account pursuant to Section 3.07, except as provided in the last sentence of Section 8.08(c).

(c) The Member Representative shall be entitled to act in his sole and absolute discretion and shall incur no liability whatsoever to the Members for any act done or omitted hereunder as the Member Representative, including errors in judgment, while acting in good faith or in reliance on the advice of representatives of the Majority Member, counsel, accountants, or other advisors, consultants, or experts. The Members shall exonerate and make no claim against the Member Representative for acting as their Member Representative, other than with respect to any act or failure to act which represents fraud, willful misconduct, or gross negligence on the part of the Member Representative. The Members shall indemnify the Member Representative and hold the Member Representative harmless against any liability incurred without fraud, willful misconduct, or gross negligence on the part of the Member Representative and arising out of or in connection with the acceptance or administration of the Member Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Member Representative. The Member Representative shall have the right to recover such expenses directly from the MR Escrow Account; provided, however, following the time that the MR Escrow Account has been fully exhausted, the Member Representative may recover 80% of such expenses from the Majority Member and 20% of such expenses from Bay Shores Investment LLC, with such Members being entitled to recover the payment of such expenses in excess of their pro rata share from the other Members pro rata based on the proportion of Company Common Units held by each Member as of immediately prior to the Closing relative to all Company Common Units held by all Members as of immediately prior to the Closing. The Majority Member, Bay Shores Investment LLC, and each Signing Member shall promptly make the payments required of them hereunder and shall pay all costs and expenses (including reasonable attorneys’ fees) incurred in any Action initiated to collect any such payments that have not been made.

(d) The Member Representative shall be compensated for his service as such based upon the amount of time devoted to such services at the normal hourly rate of the Member Representative as determined by Nossaman LLP. If the Member Representative is not a lawyer at Nossaman LLP, the Member Representative shall be compensated at a rate and on a basis established by the Majority Member. The Member Representative shall be paid such compensation from the funds in the MR Escrow Account and, if there are no remaining funds in the MR Escrow Account, the Member Representative may recover his compensation in the same way expenses may be recovered pursuant to the last sentence of Section 8.08(c) above.

(e) A decision, act, consent, or instruction of the Member Representative after the Closing, including a waiver of this Agreement pursuant to Section 10.08(b) hereof, shall constitute a decision of all the Members and shall be final, binding, and conclusive upon the Members. Parent is entitled to rely upon any such decision, act, consent, or instruction of the

Member Representative as being the decision, act, consent, or instruction of all the Members. Parent is hereby relieved from any liability to any Person for any acts done by Parent in accordance with such decision, act, consent, or instruction of the Member Representative.

(f) Parent agrees and acknowledges that concurrently with the execution of this Agreement, it has executed and delivered to the Member Representative a conflict waiver letter mutually agreeable to Parent and the Member Representative. The Members acknowledge that the Member Representative is a partner in a law firm, Nossaman LLP, which as of the date hereof provides legal services to the Company and after the Closing may provide legal services to or on behalf of Parent and its Affiliates, including the Surviving Entity. The Company with respect to periods prior to Closing and the Members acknowledge and waive any conflict of interest that may result from the representation of Parent and its Affiliates by Nossaman LLP or Mr. Mosher at a time when Mr. Mosher concurrently serves as the Member Representative.

Section 9.01. Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by either the Company or Parent if the Closing shall not have occurred by November 30, 2012 (the “Termination Date”); provided, however, that the right to terminate this Agreement under this Section 9.01(a) shall not be available to any party whose breach or failure to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to such date;

(b) by either the Company or Parent in the event that any Governmental Order enjoining or otherwise prohibiting the Transactions shall have become final and nonappealable;

(c) by the Company if a breach of any representation, warranty, covenant, or agreement on the part of Parent or Merger Sub set forth in this Agreement (including an obligation to consummate the Transactions) shall have occurred that would, if occurring or continuing on the Closing Date, cause any of the conditions set forth in Section 7.01 not to be satisfied, and such breach is not cured, or is incapable of being cured, within thirty (30) days (but no later than the Termination Date) of receipt of written notice by the Company to Parent of such breach; provided that the Company is not then in breach of this Agreement so as to cause any of the conditions set forth in Section 7.02 not to be satisfied;

(d) by Parent if a breach of any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement (including an obligation to consummate the Transactions) shall have occurred that would, if occurring or continuing on the Closing Date, cause any of the conditions set forth in Section 7.02 not to be satisfied, and such breach is not cured, or is incapable of being cured, within thirty (30) days (but no later than the Termination Date) of receipt of written notice by Parent to the Company of such breach; provided that Parent is not then in breach of this Agreement so as to cause any of the conditions set forth in Section 7.01 not to be satisfied;

(e) by either the Company or Parent, upon written notice to the other party, if the Member Approval shall not have been obtained;

(f) by either the Company or Parent in the event that one or more of the conditions to Closing contained in ARTICLE VII cannot be satisfied as of the Closing Date; provided, however, that the right to terminate this Agreement under this Section 9.01(f) shall not be available to any party in breach of this Agreement or whose failure to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, such condition not to be satisfied as of the Closing Date;

(g) by either the Company or Parent in the event that neither Parent nor Merger Sub shall have received the proceeds of the Financing at any time following the satisfaction or waiver of all the conditions set forth in Section 7.02 (other than those conditions that, by their nature, cannot be satisfied until the Closing Date, but which conditions could be satisfied if the Closing Date were the date of such termination); provided that the right to terminate this Agreement under this Section 9.01(g) shall not be available to any party in breach of this Agreement or whose failure to fulfill any obligation under Section 6.08 shall have been the cause of, or shall have resulted in, such failure of Parent or Merger Sub to receive the proceeds of the Financing;

(h) by Parent, upon written notice to the Company within five (5) Business Days after obtaining the Member Approval, if at the time of termination holders of more than five percent (5%) of the outstanding Company Common Units shall have validly exercised their dissent rights (and not withdrawn such exercise or otherwise become ineligible to effect such exercise) in respect of the Transactions; or

Section 9.02. Effect of Termination. In the event of termination of this Agreement as provided in Section 9.01, this Agreement shall forthwith become void and there shall be no Liability on the part of either party hereto or its Representatives (which shall include, for the avoidance of doubt, the Financing Sources) except that (a) this Section 9.02, Section 9.03, ARTICLE X, the indemnification provisions set forth in Section 6.08(c) and the reimbursement provisions set forth in Section 6.16(a) shall survive any such termination; (b) the Confidentiality Agreement shall continue in full force and effect in accordance with its terms; and (c) nothing herein shall relieve any party hereto from Liability for any intentional breach of this Agreement occurring prior to such termination.

(a) In the event that (i) Parent or the Company shall terminate this Agreement pursuant to Section 9.01(a) (and at such time any condition set forth in Section 7.01(a) or Section 7.01(g) is not satisfied, including the obligation of Parent or Merger Sub to consummate the Transactions, or any other condition set forth in Section 7.01 is not met due to Parent’s or Merger Sub’s breach of this Agreement or failure to fulfill any obligation under this Agreement) or the Company shall terminate this Agreement pursuant to Section 9.01(c), in either case following the satisfaction or waiver of all the conditions set forth in Section 7.02 (other than (x) conditions that have not been met due to Parent’s or Merger Sub’s breach of this Agreement or

failure to fulfill any obligation under this Agreement and (y) those conditions that, by their nature, cannot be satisfied until the Closing Date, but, in the case of clause (y), which conditions could be satisfied if the Closing Date were the date of such termination or if Parent or Merger Sub had not breached this Agreement or had not failed to fulfill its obligations under this Agreement), (ii) the Company shall terminate this Agreement pursuant to Section 9.01(f) following Parent’s or Merger Sub’s breach of this Agreement or failure to fulfill any obligation under this Agreement, in each case that shall have been the cause of, or shall have resulted in, a condition not to be satisfied as of the Closing Date that provided the basis for the termination of this Agreement pursuant to Section 9.01(f), or (iii) Parent or the Company shall terminate this Agreement pursuant to Section 9.01(g) (other than if (A) the Company has failed to deliver to Parent on the Closing Date a certificate signed by a duly authorized officer of the Company certifying that, effective as of the Closing, the EQ Representations with respect to which the Company, pursuant to Section 6.08(c), has confirmed to Parent that Parent may make in the Financing Agreement with respect to the Senior Secured Financing are true and correct in all material respects as of the Closing Date and (B) neither Parent nor Merger Sub has received the proceeds of the Senior Secured Financing and that failure is solely the result of the EQ Representations not being true and correct in all material respects as of the Closing Date), then Parent shall pay to the Company, (x) concurrently with such termination by Parent or (y) for all such terminations other than by Parent as promptly as reasonably practicable (and, in any event, within two (2) Business Days of such termination) a termination fee of $125,000,000 by wire transfer of immediately available funds to an account designated by the Company (the “Parent Termination Fee”), it being understood that in no event shall Parent be required to pay the Parent Termination Fee on more than one occasion.

(b) If the Parent Termination Fee becomes due and Parent fails to timely pay such termination fee, and, in order to obtain payment, the Company commences an Action that results in a judgment against Parent for the payment of the Parent Termination Fee, Parent shall, in addition to paying the Company the Parent Termination Fee, pay the Company its reasonable costs and expenses (including reasonable attorneys’ fees) in connection with the such Action, together with interest on such termination fee at the prime rate, as quoted in the “Money Rates” section of The Wall Street Journal, for the period commencing on the date the Parent Termination Fee was required to be paid through the date such payment was actually received by the Company.

Section 10.01. Expenses. Except as otherwise specified in this Agreement, all costs and expenses, including fees and disbursements of counsel, financial advisors, accountants, and printers and filing, processing, or other fees, incurred in connection with this Agreement and the other Transaction Documents and the Transactions shall be borne by the party incurring such costs and expenses, whether or not the Closing shall have occurred.

Section 10.02. Notices. All notices, requests, claims, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given (a) when delivered in person, (b) upon confirmation of receipt after transmittal by email (to

such address specified below or another address as such Person may subsequently specify by proper notice under this Agreement), with a confirmatory copy to be sent by overnight courier, and (c) on the next Business Day when sent by national overnight courier, in each case to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 10.02):

Section 10.03. Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be agreed upon by Parent and the Company. Thereafter, neither Parent and Merger Sub, on the one hand, nor any Business Entity or Related Entity, on the other hand, shall make, or cause to be made, any press release or public announcement in respect of this Agreement, the other Transaction Documents, or the Transactions or otherwise communicate with any news media regarding this Agreement, the other Transaction Documents, or the Transactions without the prior written consent of the other party hereto unless such press release or public announcement is otherwise required by Law or applicable stock exchange regulation, in which case Parent and the Company shall, to the extent practicable and lawful, consult with each other and cooperate as to the timing and contents of any such press release, public announcement, or communication. Notwithstanding the forgoing, Parent and Merger Sub, on the one hand, and the Business Entities and the Related Entities, on the other hand, may make, or cause to be made, public statements in respect of this Agreement, the other Transaction Documents, or the Transactions or otherwise communicate with any news media regarding this Agreement, the other Transaction Documents, or the Transactions without the prior written consent of the other party hereto so long as such statements or communications are consistent with press releases, public announcements, or other communications previously approved by the parties.

Section 10.04. Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced under any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect, provided that the economic and legal substance of the Transactions is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the Transactions are consummated as originally contemplated to the greatest extent possible.

Section 10.05. Entire Agreement. This Agreement, the other Transaction Documents, the Company Disclosure Schedule, and the Confidentiality Agreement constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between the parties hereto with respect to the subject matter hereof and thereof.

Section 10.06. Assignment. This Agreement may not be assigned by operation of Law or otherwise without the express written consent of the Company and Parent (which consent may be granted or withheld in the sole discretion of the Company or Parent), as the case may be, and any attempted assignment without such consent shall be null and void; provided, however, that Parent shall have the right to assign this Agreement to a direct or indirect wholly owned subsidiary of Parent; provided, further, that any such assignment shall not relieve Parent of its obligations hereunder.

Section 10.07. Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, each of the parties hereto; or (b) by a waiver in accordance with Section 10.08.

Section 10.08. Waiver. Any party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of any other party; (b) waive any inaccuracies in the representations and warranties of any other party contained herein or in any document delivered by any other party pursuant to this Agreement; or (c) waive compliance with any of the agreements of any other party or conditions to such obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the parties to be bound thereby. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or future exercise of any other right hereunder. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

Section 10.09. No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the 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 right, benefit, or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement; provided, however, (a) the Members and holders of Company Options are express third party beneficiaries of ARTICLE III, Section 6.12, Section 6.13, Section 6.15(b), ARTICLE VIII, and this Section 10.09 and (b) the Financing Sources are express third party beneficiaries of Section 9.02, this Section 10.09, Section 10.11, Section 10.12 and Section 10.14.

Section 10.10. Specific Performance. Subject to Section 8.04(c), each of the parties hereto acknowledges that a breach or threatened breach by any party of any of their obligations under this Agreement (including failing to take such actions as are required of it hereunder to consummate the Transactions) would give rise to irreparable harm to the other parties to this Agreement (in each instance, a “Non-Breaching Party”) for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a breach or a threatened breach by a party of any such obligations, any Non-Breaching Party shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance, and any other relief that may be available from a court of competent jurisdiction (without any requirement to

post bond or other security). Each of the parties hereto agrees that such party will not oppose the granting of a temporary restraining order, an injunction, specific performance, or any other equitable relief on the basis that there is an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. For the avoidance of doubt, the Company and the Member Representative shall not have the right under this Section 10.10 to obtain a temporary restraining order, an injunction, specific performance, or any other equitable relief that may be available from a court of competent jurisdiction to cause the consummation of the Closing if (i) Parent has complied with its obligations under Section 6.08, (ii) despite such compliance, the proceeds of the Financing are not available to Parent or Merger Sub, and (iii) upon termination of this Agreement, the Parent Termination Fee shall be due and payable in accordance with Section 9.03.

Section 10.11. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. All Actions arising out of or relating to this Agreement (including any Action involving the Financing Sources) shall be heard and determined exclusively in any federal court sitting in the Borough of Manhattan of the City of New York; provided, however, that if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any New York state court sitting in the Borough of Manhattan of the City of New York. Consistent with the preceding sentence, the parties hereto hereby (a) submit to the exclusive jurisdiction of any federal or state court sitting in the Borough of Manhattan of the City of New York for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto (including any Action involving the Financing Sources); (b) consent to service of process in accordance with the procedure set forth in Section 10.02; and (c) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts.

Section 10.12. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS (INCLUDING ANY ACTION INVOLVING THE FINANCING SOURCES). EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY SUCH ACTION, SEEK TO ENFORCE THE FOREGOING WAIVER; AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.12.

Section 10.13. Counterparts. This Agreement may be executed and delivered (including by facsimile or other means of electronic transmission, such as by electronic mail in “pdf” form) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

Section 10.14. Limitation on Liability. Notwithstanding anything to the contrary in this Agreement, the Company agrees on behalf of itself and its Subsidiaries that it shall not assert any claim or bring any action, or support any claim or action brought by another Person (whether in equity, in contract or tort, or otherwise), in any proceeding or forum, against any Financing Source or any former, current, or future stockholder, controlling person, director, officer, employee, general or limited partner, member, manager, Affiliate, agent, or advisor thereof (excluding, in each case, Parent, Merger Sub, and their respective Affiliates) relating to or arising out of this Agreement or the Financing Letters or the transactions contemplated hereby or thereby, including any action or claim arising out of or relating to any breach, termination, or failure under this Agreement, and no Financing Source or any former, current, or future stockholder, controlling person, director, officer, employee, general or limited partner, member, manager, Affiliate, agent, or advisor thereof (excluding, in each case, Parent, Merger Sub, and their respective Affiliates) shall have any liability or obligation to the Company or any of its Subsidiaries relating to or arising out of this Agreement or the Financing Letters or the transactions contemplated hereby or thereby, including any action or claim arising out of or relating to any breach, termination, or failure under this Agreement.

IN WITNESS WHEREOF, each of the parties hereto has caused this Agreement to be executed as of the date first written above by its representative thereunto duly authorized.
