However, upon the vesting of Unvested Earnout Units the holder of each applicable Earnout Unit shall be entitled to a cash payment from the Company in an amount equal to the distributions such Member would have received pursuant to Section 4.01(a) had such Unvested Earnout Unit been vested beginning at the Fathom Effective Time and ending on the day prior to the date such Unvested Earnout Unit vests.

(c) Tax Distributions.

(i) With respect to each Fiscal Year or portion thereof ending after the Effective Date, the Company shall, to the extent permitted by applicable Law, make cash distributions (“Tax Distributions”) to each Member in an amount to ensure that each such Member receives a distribution at least equal to such Member’s Assumed Tax Liability, if any, with respect to the relevant taxable period to which the distribution relates. For the avoidance of doubt, such Tax Distributions shall be determined in accordance with Section 4.01(c)(ii). Tax Distributions pursuant to this Section 4.1(c) (i) shall be estimated by the Company on a quarterly basis and, to the extent feasible, shall be distributed to the Members (together with a statement showing the calculation of such Tax Distribution and an estimate of the Company’s net taxable income allocable to each Member for such period) on a quarterly basis five business days prior to April 15th, June 15th, September 15th and January 15th (of the succeeding year) (or such other dates for which individuals are required to make quarterly estimated tax payments for U.S. federal income tax purposes) (each, a “Quarterly Tax Distribution”); provided, that the foregoing shall not restrict the Company from making a Tax Distribution on any other date. Quarterly Tax Distributions shall take into account the estimated taxable income or loss of the Company for the Fiscal Year through the end of the relevant quarterly period. A final accounting for Tax Distributions shall be made for each Fiscal Year after the allocation of the Company’s

23

actual net taxable income or loss has been determined and any shortfall in the amount of Tax Distributions a Member received for such Fiscal Year based on such final accounting shall promptly be distributed to such Member. For the avoidance of doubt, any excess Tax Distributions a Member receives with respect to any Fiscal Year shall reduce future Tax Distributions otherwise required to be made to such Member with respect to any subsequent Fiscal Year.

(ii) A Tax Distribution to a Member in respect of any Unit shall be charged against current or future distributions to which such Member would otherwise have been entitled under Section 4.01(a) or Section 9.03(c) in respect of such Unit; provided, however, that all Units shall participate in distributions made pursuant to this Section 4.01(c) on a pro rata basis. Notwithstanding the foregoing, (A) any distributions made pursuant to this Section 4.01(c) shall be made to the Members on a pro rata basis, (B) to the extent of Available Cash, the pro rata amount to be distributed to each Member shall be calculated based on the distribution to the Member that would have the highest Tax Distribution under this Section 4.01(c) on a per-Unit basis, calculated without regard to this sentence and (C) if there is insufficient Available Cash to make all of the distributions described in clause (B), the amount that would have been distributed to each Member pursuant to clause (B) shall be reduced on a pro rata basis and the Company shall make future Tax Distributions as soon as there is sufficient Available Cash to pay the remaining portion of the Tax Distributions to which such Members were otherwise entitled under clause (B).

(iii) In the event of any audit by a taxing authority that has been finally settled and as such, affects the calculation of any Member’s Assumed Tax Liability for any taxable year (other than an audit conducted pursuant to the Partnership Audit Provisions for which no election is made pursuant to Section 6226 thereof and the Treasury Regulations promulgated thereunder), or in the event the Company files an amended tax return, each Member’s Assumed Tax Liability with respect to such year shall be recalculated by giving effect to such event (for the avoidance of doubt, taking into account interest or penalties). Any shortfall in the amount of Tax Distributions the Members and former Members received for the relevant taxable years based on such recalculated Assumed Tax Liability promptly shall be distributed to such Members and the successors of such former Members, except, for the avoidance of doubt, to the extent Distributions were made to such Members and former Members pursuant to Section 4.01(a) and this Section 4.01(c) in the relevant taxable years sufficient to cover such shortfall.

(d) Notwithstanding anything to the contrary set forth herein, the Managing Member shall cause any distributions paid to any Subsidiary of the Managing Member who holds Units to distribute the full amount of such distribution to the Managing Member, and the Managing Member shall take all actions necessary to cause such distributions.

Section 4.02 Distributions Upon Liquidation. Distributions made upon dissolution of the Company shall be made as provided in Section 9.03.

Section 4.03 Limitations on Distribution.

This Section 5.05(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

(c) Gross Income Allocation. If any Member has a deficit Capital Account at the end of any taxable year which is in excess of the sum of (i) the amount such Member is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Section 1.704-2(g)(1) and 1.704- 2(i)(5), each such Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this Section 5.05(c) shall be made only if and to the extent that a Member would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if Section 5.05(b) and this Section 5.05(c) were not in this Agreement.

(d) Nonrecourse Deductions. Nonrecourse Deductions shall be allocated to the Members in accordance with their interests in the Company.

26

(e) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable period shall be allocated to the Member who bears the economic risk of loss with respect to the liability to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulations Section 1.704-2(j).

(f) Ameliorative Allocations. Any special allocations of income or gain pursuant to Sections 5.05(b) or 5.05(c) hereof shall be taken into account in computing subsequent allocations pursuant to Section 5.04 and this Section 5.05(f), so that the net amount of any items so allocated and all other items allocated to each Member shall, to the extent possible, be equal to the net amount that would have been allocated to each Member if such allocations pursuant to Sections 5.05(b) or 5.05(c) had not occurred.

(g) Notwithstanding anything to the contrary contained in this Agreement, (1) no allocation (of Profits or Losses or otherwise) shall be made in respect of any Earnout Units in determining Capital Accounts unless and until such Units are vested upon the occurrence of an Earnout Vesting Event, if any, and (2) in the event the Carrying Value of any Company asset is adjusted pursuant to clause (d) of the definition of Carrying Value, any Profits or Losses resulting from such adjustment shall, in the manner reasonably determined by the Managing Member, be allocated among the Members such that the Capital Account balance relating to each Class A Unit (excluding any Unvested Earnout Units) is equal in amount immediately after making such allocation, after taking into account the non-distribution amounts (as applicable) in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s); provided, that if the foregoing allocations pursuant to clause (2) are insufficient to cause the Capital Account balance relating to each Class A Unit to be so equal in amount, then the Managing Member, in its reasonable discretion, shall cause a Capital Account reallocation in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(3) to cause the Capital Account balance relating to each Class A Unit to be so equal in amount.

Section 5.06 Tax Allocations. For U.S. federal income tax purposes, each item of income, gain, loss and deduction of the Company shall be allocated among the Members in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that in the case of any asset the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated, solely for income tax purposes, to account for such difference using the “traditional method” without curative allocations under Treasury Regulations Section 1.704-3(b). Section 5.07. Tax Advances. To the extent the Managing Member reasonably believes that the Company is required by law to withhold or to make tax payments on behalf of or with respect to any Member, or the Company is subjected to tax itself by reason of the status of any Member (including any taxes paid pursuant to Section 6225 of the Code) (“Tax Advances”), the Managing Member may cause the Company to withhold such amounts and cause the Company to make such tax payments as so required. All Tax Advances made on behalf of a Member shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Member. For all purposes of this Agreement such Member shall be treated as having received the amount of the distribution that is equal to the Tax Advance. Each Member hereby agrees to indemnify and hold harmless the Company and the other Members from and against any liability

27

(including any liability for taxes, penalties, additions to tax or interest, but excluding any penalties, additions to tax or interest imposed as a result of the Company’s failure to withhold or make a tax payment on behalf of such Member which withholding or payment is required pursuant to applicable Law) with respect to income or Tax Advances attributable to such Member; provided, that any remaining Tax Advance with respect to any Member shall be required to be repaid by such Member in full prior to or in connection with (and as a condition of) any Transfer or any Class A Exchange. The obligation of a Member set forth in this Section 5.07 shall survive the withdrawal of a Member from the Company or any Transfer of a Member’s interest.

Section 5.07 Tax Matters. The Managing Member shall act as or designate a Person to act as the “partnership representative” pursuant to the Partnership Audit Provisions (the “Partnership Representative”) and such Person shall have the power to exercise any and all rights that it is or may be entitled to exercise in that capacity. The Partnership Representative shall keep the Continuing Members timely and reasonably informed as to all material tax audits, actions, examinations or proceedings relating to the Company or any of its Subsidiaries (“ Tax Proceedings”). The Partnership Representative shall have the exclusive right to represent the Company in respect of any Tax Proceedings. The Members shall cooperate as reasonably requested by the Partnership Representative in connection with any election or decision made by the Partnership Representative acting in that capacity (including by filing amended tax returns and providing information requested).

Section 5.08 Other Allocation Provisions. Certain of the foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations. In addition to amendments effected in accordance with Section 11.12 or otherwise in accordance with this Agreement, Sections 5.03, 5.04 and 5.05 may also, so long as any such amendment does not materially change the relative economic interests of the Members and the prior written consent of the Continuing Member Representative has been obtained, be amended at any time by the Managing Member if necessary, in the opinion of tax counsel to the Company, to comply with such regulations or any applicable Law.

ARTICLE VII

COMPANY UNITS

Section 7.01 Units.

(a) Units. Subject to the provisions of this Agreement and subject to the approval of the Board of Directors, the Company shall be authorized to issue from time to time such number of Units and other Equity Securities as the Managing Member shall determine in accordance with and subject to the restrictions in this Section 7.01 and Section 7.02. Subject to this Section 7.01 and Section 7.02, each authorized Unit may be issued pursuant to such agreements as the Managing Member shall approve, including pursuant to warrants, options, or other rights or property to acquire Units or that may be converted into Units. Subject to the approval of the Board of Directors, the Company may reissue any Units that have been repurchased or acquired by the Company; provided that any such issuance, and the admission of any Person as a Member in connection therewith, is otherwise made in accordance with and subject to the restrictions in this LLC Agreement.

Notwithstanding the foregoing, other than in connection with any subdivision or combination in accordance with Section 7.01(j) or (k) or any Reclassification Event, from and after the Effective Date the Managing Member shall not be authorized to issue any Earnout Units. The Units shall be uncertificated. The Company shall not, and the Managing Member shall not cause the Company to, issue any Units if such issuance would result in the Company having more than 100 partners, within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)).

(b) Outstanding Units. Immediately after the Fathom Effective Time, the Units comprise Class A Units (including the Earnout Units, comprising Tier 1 Earnout Units, Tier 2 Earnout Units and Tier 3 Earnout Units). Except as otherwise provided in this Agreement, each outstanding Class A Unit (other than the Earnout Units) shall be identical to each other Class A Unit (other than the Earnout Units), each outstanding Tier 1 Earnout Unit shall be identical to each other Tier 1 Earnout Unit, each outstanding Tier 2 Earnout Unit shall be identical to each other Tier 2 Earnout Unit, and each outstanding Tier 3 Earnout Unit shall be identical to each other Tier 3 Earnout Unit. The Managing Member’s interest in its capacity as such shall be a non-economic interest in the Company, which does not entitle the Managing Member, solely in its capacity as such, to any Units, distributions or Tax Distributions.

(c) Schedule of Members. The Company shall maintain a schedule, appended hereto as Exhibit A (as updated and amended from time to time in accordance with the terms of this Agreement and current as of the date set forth therein), which shall include: (i) the name and address of each Member; (ii) the aggregate number of and type of Units issued and outstanding and held by each Member; and (iii) each Member’s Capital Contributions following the Fathom Effective Time. The number of Units of each Class held by each Member at the completion of the Equity Transactions is as set forth in the Schedule of Members (as of the Effective Date).

30

(d) Earnout Units. Each Earnout Unit will be held in accordance with this Agreement unless and until an Earnout Vesting Event occurs with respect to such Earnout Unit or such Earnout Unit is forfeited in accordance with Section 7.01(d)(ii).

(i) From and after the Effective Date until the occurrence of the applicable Earnout Vesting Event, each Tier 1 Earnout Unit, Tier 2 Earnout Unit and Tier 3 Earnout Unit shall be an Unvested Earnout Unit. Upon the occurrence of (i) a Tier 1 Earnout Vesting Event, with respect to the Tier 1 Earnout Units, (ii) a Tier 2 Earnout Vesting Event, with respect to the Tier 2 Earnout Units or (iii) a Tier 3 Earnout Vesting Event, with respect to the Tier 3 Earnout Units, such Earnout Units shall immediately and automatically without any further action on the part of the holder thereof or any other Person (including the Company and the Managing Member) vest and thereafter shall have all rights and privileges of a Class A Unit under this Agreement from and after the Earnout Vesting Date (together with the right to receive any applicable distributions under Section 4.01(b)). On the Effective Date, with respect to any Earnout Unit issued to a Continuing Member, Pubco shall issue to such Continuing Member one share of Class B Common Stock at par value for cash.

(ii) To the extent that, on or before the fifth (5th) anniversary of the Effective Date, an applicable Earnout Vesting Event has not occurred with respect to an Earnout Unit (and as a result such Earnout Unit is an Unvested Earnout Unit), then immediately and without any further action under this Agreement, on the date that is the fifth (5th) anniversary of the Effective Date, any such Earnout Units shall automatically be forfeited and surrendered to the Company and be canceled and extinguished for no consideration and each corresponding share of Class B Common Stock shall automatically be forfeited and surrendered to Pubco and be canceled and extinguished for no consideration.

(iii) [Reserved.]

(iv) The parties hereto intend that, for U.S. federal income tax purposes, (a) the Earnout Units received by the Continuing Members in connection with the transaction contemplated in the Business Combination Agreement not be treated as being received in connection with the performance of services and (b) no such Member be treated as having taxable income or gain as a result of such receipt of such Earnout Units or as a result of holding any such Earnout Units at the time of any Earnout Vesting Event (for avoidance of doubt, excluding any allocations as a result of the last sentence of Section 5.03) and the Company shall prepare and file all tax returns consistent therewith unless otherwise required by a “determination” within the meaning of Section 1313 of the Code. Notwithstanding (and without limiting) the foregoing, each of the Members shall, within thirty (30) days of the Effective Date, file with the IRS (via certified mail, return receipt requested) on a protective basis a completed election under Section 83(b) of the Code and the Treasury Regulations thereunder with respect to any Earnout Units so received and, upon such filing, shall thereafter notify the Company that such Member has made such timely filing and provide the Company with a copy of such election.

(h) Pubco Debt Issuance. If at any time Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) issues Debt Securities, Pubco or such Subsidiary shall transfer to the Company, the net proceeds received by Pubco or such Subsidiary, as applicable, in exchange for such Debt Securities in a manner that directly or indirectly burdens the Company with the repayment of the Debt Securities (provided, that, the Company shall not be required to reimburse hereunder any costs or expenses which were netted off the gross proceeds received).

(i) New Company Issuances. Except pursuant to Section 8.04, (x) the Company may not issue any additional Units to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers an equal number of newly-issued shares of Class A Common Stock (or relevant Equity Security of such Subsidiary) to another Person or Persons, and (ii) such issuance is in accordance with Section 7.01(g), and (y) the Company may not issue any other Equity Securities of the Company to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers, to another Person, an equal number of newly-issued shares of Equity Securities of Pubco or such Subsidiary with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of the Company, and (ii) such issuance is in accordance with Section 7.01(g).

33

(ii) The Company may not redeem, repurchase or otherwise acquire (x) any Class A Units from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) an equal number of shares of Class A Common Stock for the same price per security from holders thereof or (y) any other Equity Securities of the Company from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) for the same price, and substantially equivalent form of consideration, per security an equal number of Equity Securities of Pubco (or such Subsidiary) of a corresponding class or series with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of Pubco or such Subsidiary.

If, notwithstanding the provisions of this Section 8.03(a), all or any portion of a Member’s Units are Transferred by such Member in violation of this Section 8.03(a), involuntarily, by operation of Law or otherwise, the Transferee of such Units (or portion thereof) shall not be admitted to the Company as a Member nor be entitled to any rights as a Member under this Agreement, and the Transferor will continue to be bound by all obligations under this Agreement. Any attempted or purported Transfer of all or a portion of a Member’s Units in violation of this Section 8.03(a) shall, to the fullest extent permitted by Law, be null and void ab initio and of no force or effect whatsoever.

Any Class A Exchange under this Section 8.04 must be with respect to a number of Class A Units at least equal to the Maximum Exchange Amount.

(ii) (iii) For the avoidance of doubt, Unvested Earnout Units are not permitted to be exchanged pursuant to this Section 8.04, and in no event shall the Company or Pubco effect an exchange of an Earnout Unit unless and until an Earnout Vesting Event and Earnout Vesting Date has occurred with respect to such Earnout Unit and it has vested in accordance with the terms hereof.

(b) Exchange Procedures.

(i) A Class A Exchanging Member shall exercise its right to make a Class A Exchange as set forth in Section 8.04(a) above by providing such Class A Exchange Notice during normal business hours at the principal executive office of Pubco and the Company (or otherwise in accordance with Section 11.02). Within three (3) Business Days following its receipt of a Class A Exchange Notice, the Managing Member may elect to settle all or a portion of the Class A Exchanged Units in cash in an amount equal to the Class A Cash Amount (in lieu of shares of Class A Common Stock), by giving written notice of such election to the Class A Exchanging Member within such three (3) Business Day period (such notice, the “Cash Exchange Notice”). The Cash Exchange Notice shall set forth the portion of the Class A Exchanged Units subject to the Class A Exchange which shall be exchanged for cash in lieu of Class A Common Stock. To the extent any Class A Exchange relates to the exercise of the Class A Exchanging Member’s registration rights under the Registration Rights Agreement, Pubco and the Company shall cooperate in good faith with such Class A Exchanging Member to exercise such Class A

37

Exchange in a manner which preserves such Class A Exchanging Member’s rights thereunder. At any time following the delivery of a Cash Exchange Notice and prior to the Class A Exchange Date, the Managing Member may elect (by giving written notice of such election to the Class A Exchanging Member) to revoke the Cash Exchange Notice with respect to all or any portion of the Class A Exchanged Units and instead deliver the applicable Class A Exchanged Shares with respect to any such Class A Exchanged Units on the Class A Exchange Date.

(ii) [Reserved].

(iii) Each Class A Exchange shall be consummated on the Class A Exchange Date. On the Class A Exchange Date (to be effective immediately prior to the close of business on the Class A Exchange Date), (a) Pubco shall contribute to the Company for delivery to the Class A Exchanging Member (x) the Class A Exchanged Shares with respect to such Class A Exchanged Units not subject to a Cash Exchange Notice and (y) the Class A Cash Amount with respect to any Class A Exchanged Units subject to a Cash Exchange Notice, (b) the Class A Exchanging Member shall transfer and surrender the Class A Exchanged Units to the Company, free and clear of all liens and encumbrances, (c) the Company shall issue to Pubco a number of Class A Units equal to the number of shares of Class A Common Stock to be delivered pursuant to clause (a)(x), (d) solely to the extent necessary in connection with a Class A Exchange, Pubco shall undertake all actions, including an issuance, reclassification, distribution, division or recapitalization, with respect to the Class A Common Stock necessary in order to maintain a one-to-one ratio between the number of Class A Units owned by Pubco, directly or indirectly, and the number of outstanding shares of Class A Common Stock, taking into account the issuance in clause (c), any Class A Exchanged Shares, and any other action taken in connection with this Section 8.04, (e) the Company shall (x) cancel the redeemed Class A Units which were Class A Exchanged Units held by the Class A Exchanging Member and (y) transfer to the Class A Exchanging Member the Class A Cash Amount and/or the Class A Exchanged Shares, as applicable, and (f) Pubco shall cancel the surrendered shares of Class B Common Stock. Upon the Class A Exchange of all of a Member’s Class A Units, such Class A Member shall cease to be a Class A Member of the Company.

(iv) The Company and each Class A Exchanging Member shall bear their own expenses in connection with the consummation of any Class A Exchange, except that the Company shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Class A Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered in a name other than that of the Class A Exchanging Member, then such Class A Exchanging Member and/or the person in whose name such shares are to be delivered shall pay to the Company the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange or shall establish to the reasonable satisfaction of the Company that such tax has been paid or is not payable (and shall indemnify the Company in the event such transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange are not so paid).

38

(v) Pubco may adopt reasonable procedures for the implementation of the Class A Exchange provisions set forth in this Section 8.04; provided that without the consent of each Continuing Member, Pubco shall not adopt any procedures inconsistent with or that impair or adversely affect the rights of a Member to Exchange Class A Units pursuant to this Agreement. A Class A Exchanging Member may not revoke a Class A Exchange Notice delivered pursuant to Section 8.04(a) above without the consent of the Managing Member, which consent may not be unreasonably withheld, delayed or conditioned.

(vi) Notwithstanding anything to the contrary herein, additional restrictions may be imposed on Class A Exchanges by the Managing Member as provided in Section 8.06(b).

(c) Adjustment. If there is: (i) any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Class A Units that is not accompanied by an identical subdivision or combination of the Class A Common Stock; or (ii) any subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Common Stock that is not accompanied by an identical subdivision or combination of the Units, then, in each case, to the extent necessary to maintain the economic equivalency in the value surrendered for exchange and the value received, the Managing Member shall in good faith adjust the number of shares of Class A Common Stock for which a Class A Unit is entitled to be exchanged under this Section 8.04 accordingly. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed into another security, securities or other property, then upon any subsequent Class A Exchange, a Class A Exchanging Member shall be entitled to receive the amount of such security, securities or other property that such Class A Exchanging Member would have received if such Class A Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. Except as may be required in the immediately preceding sentence, no adjustments in respect of distributions shall be made upon a Class A Exchange.

(d) Class A Common Stock to be Issued.

(i) Pubco shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon a Class A Exchange, such number of shares of Class A Common Stock as shall be deliverable upon any such Class A Exchange; provided that nothing contained herein shall be construed to preclude the Company from satisfying its obligations in respect of the Class A Exchange by delivery of shares of Class A Common Stock which are held in the treasury of Pubco or any of its subsidiaries (other than the Company or any of its subsidiaries) or by delivery of purchased shares of Class A Common Stock (which may or may not be held in the treasury of Pubco or any subsidiary thereof). Pubco and the Company covenant that all Class A Common Stock issued upon a Class A Exchange will, upon issuance, be validly issued, fully paid and non-assessable.

39

(ii) Pubco and the Company covenant and agree that, to the extent that a Registration Statement under the Securities Act is effective and available for shares of Class A Common Stock to be delivered with respect to any Class A Exchange, shares that have been registered under the Securities Act shall be delivered in respect of such Class A Exchange. In the event that any Class A Exchange in accordance with this Agreement is to be effected at a time when any required registration has not become effective or otherwise is unavailable, upon the request and with the reasonable cooperation of the applicable Class A Exchanging Member, Pubco and the Company shall use commercially reasonable efforts to promptly facilitate such Exchange pursuant to any reasonably available exemption from such registration requirements. Pubco and the Company shall use commercially reasonable efforts to list the Class A Common Stock required to be delivered upon a Class A Exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Class A Common Stock may be listed or traded at the time of such delivery.

(e) Pubco Offers. In the event that a tender offer, share exchange offer, or take-over bid or similar transaction with respect to Class A Common Stock or another Equity Security of Pubco (a “Pubco Offer”) is proposed by Pubco or is proposed to Pubco or its stockholders, the holders of Class A Units (or such other Equity Security of the Company corresponding to such Pubco Equity Security) shall be permitted to participate in such Pubco Offer by delivery of a Class A Exchange Notice (which Class A Exchange Notice shall be effective immediately prior to the consummation of such Pubco Offer (and, for the avoidance of doubt, shall be contingent upon such Pubco Offer and not be effective if such Pubco Offer is not consummated)). In the case of a Pubco Offer, Pubco shall use its reasonable best efforts to take all such actions and do all such things as are necessary or desirable to enable and permit the holders of Class A Units or other Equity Security to participate in such Pubco Offer to the same extent or on an economically equivalent basis as the holders of shares of Class A Common Stock or other Equity Security without discrimination; provided that, without limiting the generality of this sentence (and without limiting the ability of any Member holding Class A Units or such other Equity Security to consummate a Class A Exchange at any time pursuant to the terms of this Agreement), the Managing Member shall use its reasonable best efforts to ensure that such holders of Class A Units or such other Equity Security may participate in such Pubco Offer without being required to effect a Class A Exchange of their Class A Units and cancel their shares of Class B Common Stock, as the case may be, (or, if so required, to ensure that any such Class A Exchange and cancelation shall be effective only upon, and shall be conditional upon, the closing of the transactions contemplated by the Pubco Offer). For the avoidance of doubt, in no event shall the holders of Class A Units be entitled to receive in such Pubco Offer aggregate consideration for each Class A Unit and share of Class B Common Stock, taken together, that is greater than or less than the consideration payable in respect of each share of Class A Common Stock in connection with such Pubco Offer (it being understood that payments under or in respect of the Tax Receivable Agreement shall not be considered part of any such consideration, and shall be in addition thereto).

40

(f) Pubco Call Rights. Notwithstanding anything to the contrary contained in this Section 8.04, with respect to any Class A Exchange Notice, a Class A Exchanging Member shall be deemed to have offered to sell its Class A Exchanged Units as described in any Class A Exchange Notice directly to Pubco (rather than to the Company), and Pubco may, by delivery of a written notice to the Class A Exchanging Member no later than three (3) Business Days following the giving of a Class A Exchange Notice, in accordance with, and subject to the terms of, this Section 8.4(f) (such notice, a “Pubco Call Notice”), elect to purchase directly and acquire such Class A Exchanged Units on the Class A Exchange Date by paying to the Class A Exchanging Member (or such other Person specified in the Class A Exchange Notice) the Class A Exchanged Shares and/or Class A Cash Amount with respect to the Class A Exchanged Units, whereupon Pubco shall acquire the Class A Exchanged Units on the Class A Exchange Date and be treated for all purposes of this Agreement as the owner of such Class A Units. Except as otherwise provided in this Section 8.04(f), an exercise of the call right of Pubco set forth in this Section 8.04(f) shall be consummated pursuant to the same timeframe and in the same manner as the relevant Class A Exchange would have been consummated if Pubco had not given a Pubco Call Notice, in each case as relevant.

(g) Distribution Rights. No Class A Exchange shall impair the right of the Class A Exchanging Member to receive any distributions payable on the Units redeemed pursuant to such Class A Exchange in respect of a record date that occurs prior to the Class A Exchange Date for such Class A Exchange. No Class A Exchanging Member, or a Person designated by a Class A Exchanging Member to receive shares of Class A Common Stock, shall be entitled to receive, with respect to such record date, distributions or dividends both on Class A Units redeemed by the Company from such Class A Exchanging Member and on shares of Class A Common Stock received by such Class A Exchanging Member, or other Person so designated, if applicable, in such Class A Exchange.

(h) Tax Treatment. For U.S. federal and applicable state and local income tax purposes, each of the Class A Exchanging Member, the Company and Pubco agree to treat each Class A Exchange as a sale by the Class A Exchanging Member of the Class A Exchanging Member’s Class A Units (together with a corresponding number of outstanding shares of Class B Common Stock, which shares shall not be allocated economic value in excess of par value) to Pubco in exchange for the Class A Common Stock.

Section 8.05 [Reserved].

Section 8.06 Further Restrictions.

(a) Notwithstanding any contrary provision in this Agreement, other than with respect to Transfers in accordance with Section 8.04, in no event may any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that:

(i) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit;

41

(ii) such Transfer would require the registration of such transferred Unit or of any Class of Unit pursuant to any applicable U.S. federal or state securities laws (including, without limitation, the Securities Act or the Exchange Act) or other non-U.S. securities laws (including Canadian provincial or territorial securities laws) or would constitute a non-exempt distribution pursuant to applicable provincial or state securities laws; or

(iii) such Transfer would cause (i) all or any portion of the assets of the Company to (A) constitute “plan assets” (under ERISA, the Code or any applicable Similar Law) of any existing or contemplated Member, or (B) be subject to the provisions of ERISA, Section 4975 of the Code or any applicable Similar Law, or (ii) the Managing Member to become a fiduciary with respect to any existing or contemplated Member, pursuant to ERISA, any applicable Similar Law, or otherwise.

(b) Notwithstanding any contrary provision in this Agreement, in no event shall any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that such Transfer would pose a material risk that such Transfer would (i) be considered to be effected on or through an “established securities market” or a “secondary market or the substantial equivalent thereof” as such terms are used in Treasury Regulations Section 1.7704-1, (ii) result in the Company having more than 100 partners, within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)), or (iii) cause the Company to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the Treasury Regulations promulgated thereunder. In addition, notwithstanding any contrary provision in this Agreement, to the extent the Managing Member reasonably determines that additional restrictions on Transfers (including, for the avoidance of doubt, Class A Exchanges) are advisable to minimize the risk that the Company is not treated as a “publicly traded partnership” under Section 7704 of the Code, the Managing Member shall impose such additional restrictions on Transfers as the Managing Member reasonably determines to be so advisable.

(c) To the fullest extent permitted by law, any Transfer in violation of this Article VIII shall be deemed null and void ab initio and of no effect.

Section 8.07 Rights of Assignees. The Transferee of any Permitted Transfer permitted pursuant to this Article VIII will be an assignee only (“Assignee”), and only will receive, to the extent transferred, the distributions and allocations of income, gain, loss, deduction, credit or similar item to which the Member which transferred its Units would be entitled, and such Assignee will not be entitled or enabled to exercise any other rights or powers of a Member, such other rights, and all obligations relating to, or in connection with, such interest remaining with the transferring Member, unless and until such time as such Transferee is admitted to the Company as a Member pursuant to Section 8.09. The transferring Member will remain a Member even if it has transferred all of its Units to one or more Assignees until such time as all such Assignee(s) have been admitted to the Company as a Member pursuant to Section 8.09.

42

Section 8.08 Admissions, Resignations and Removals.

(a) Pubco shall not, by any means, resign as, cease to be or be replaced as Managing Member except in compliance with this Section 8.08 and except with the approval of a majority of the independent directors serving on the Board of Directors. No termination or replacement of Pubco as Managing Member shall be effective unless proper provision is made, in compliance with this Agreement, so that the obligations of Pubco, its successor by merger (if applicable) and any new Managing Member and the rights of all Members under this Agreement and applicable Law remain in full force and effect. No appointment of a Person other than Pubco (or its successor by merger, as applicable) as Managing Member shall be effective unless

(b) the new Managing Member executes a joinder to this Agreement and agrees to be bound by the terms and conditions in this Agreement, and

(c) Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable) provide all other Members with contractual rights, directly enforceable by such other Members against Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable), to cause (i) Pubco to comply with all Pubco’s obligations under this Agreement (including its obligations under Section 8.04 and 7.01(c)(iii)) other than those that must necessarily be taken solely in its capacity as Managing Member and (ii) the new Managing Member to comply with all the Managing Member’s obligations under this Agreement.

(d) No Member will be removed or entitled to resign from being a Member of the Company except in accordance with Section 8.10 hereof. Any additional Managing Member or substitute Managing Member admitted as a Managing Member of the Company pursuant to this Section 8.08 is hereby authorized to, and shall, continue the Company without dissolution.

(e) Except as otherwise provided in Article IX or the Act, no admission, substitution, resignation or removal of a Member will cause the dissolution of the Company. To the fullest extent permitted by law, any purported admission, resignation or removal that is not in accordance with this Agreement shall be null and void.

Section 8.09 Admission of Assignees as Substitute Members. An Assignee will become a substitute Member only if and when each of the following conditions is satisfied:

(a) the Managing Member consents in writing to such admission (to the extent required in accordance with Section 8.03);

(b) if required by the Managing Member, the Managing Member receives written instruments (including, without limitation, copies of any instruments of Transfer) that are in a form satisfactory to the Managing Member; and

(c) such Assignee signs a joinder or counterpart to this Agreement agreeing to become a party to and bound by this Agreement as a substitute Member.

Section 8.10 Resignation and Removal of Members. Subject to Section 8.07, if a Member (other than the Managing Member) ceases to hold any Units, then such Member shall cease to be a Member and to have the power to exercise any rights or powers of a member of the Company, and shall be deemed to have resigned from the Company.

43

ARTICLE IX

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 9.01 No Dissolution. Except as required by the Act, the Company shall not be dissolved by the admission of additional Members or resignation of Members in accordance with the terms of this Agreement. The Company may be dissolved, liquidated, wound up and terminated only pursuant to the provisions of this Article IX, and the Members hereby irrevocably waive any and all other rights they may have to cause a dissolution of the Company or a sale or partition of any or all of the Company assets.

Section 9.02 Events Causing Dissolution. The Company shall be dissolved and its affairs shall be wound up upon the occurrence of any of the following events (each, a “Dissolution Event”):

(a) the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act upon the finding by a court of competent jurisdiction that it is not reasonably practicable to carry on the business of the Company in conformity with this Agreement;

(b) any event which makes it unlawful for the business of the Company to be carried on by the Members;

(c) the written consent of all Members;

(d) at any time there are no Members, unless the Company is continued in accordance with the Act; or

(e) the determination of the Managing Member, with the consent of the Continuing Member Representative for so long as the Continuing Members hold Units; provided that in the event of a dissolution pursuant to this clause (e), the relative economic rights of each Class of Units immediately prior to such dissolution shall be preserved to the greatest extent practicable with respect to distributions made to Members pursuant to Section 9.03 below in connection with the winding up of the Company, taking into consideration tax and other legal constraints that may adversely affect one or more parties hereto and subject to compliance with applicable laws and regulations, unless, and to the extent that, with respect to any Class of Units, holders of not less than 75% of the Units of such Class consent in writing to a treatment other than as described above; provided, that prior to the occurrence of a Tier 1 Earnout Vesting Event, a Tier 2 Earnout Vesting Event or a Tier 3 Earnout Vesting Event with respect to the Tier 1 Earnout Units, the Tier 2 Earnout Units and the Tier 3 Earnout Units, respectively, such Units shall not have any economic rights under this Agreement.

Section 9.03 Distribution upon Dissolution. Upon dissolution, the Company shall not be terminated and shall continue until the winding up of the affairs of the Company is completed. Upon the winding up of the Company, the Managing Member, or any other Person designated by the Managing Member (the “Liquidation Agent”), shall take full account of the assets and liabilities of the Company and shall, unless the Managing Member determines otherwise, liquidate the assets of the Company as promptly as is consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be applied and distributed in the following order:

44

(a) First, to the satisfaction of debts and liabilities of the Company (including satisfaction of all indebtedness to Members and/or their Affiliates to the extent otherwise permitted by law) including the expenses of liquidation, and including the establishment of any reserve which the Liquidation Agent shall deem reasonably necessary for any contingent, conditional or unmatured contractual liabilities or obligations of the Company (“ Contingencies”). Any such reserve may be paid over by the Liquidation Agent to any attorney-at-law, or acceptable party, as escrow agent, to be held for disbursement in payment of any Contingencies and, at the expiration of such period as shall be deemed advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter provided in this Section 9.03;

(b) Second, to the satisfaction of (i) any payments due pursuant to Section 4.01(b), if any, to the Members holding Class A Units for which such distributions are due, pro rata in accordance with all such Members’ respective Class A Units for which such distributions are due; and

(c) The balance, if any, to the Members, pro rata in accordance with the Members’ respective Class A Units other than Unvested Earnout Units.

Section 9.04 Time for Liquidation. A reasonable amount of time shall be allowed for the orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation.

Section 9.05 Termination. The Company shall terminate when all of the assets of the Company, after payment of or due provision for all debts, liabilities and obligations of the Company, shall have been distributed to the holders of Units in the manner provided for in this Article IX, and the Certificate shall have been cancelled in the manner required by the Act.

Section 9.06 Claims of the Members. The Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members shall have no recourse against the Company or any other Member or any other Person. No Member with a negative balance in such Member’s Capital Account shall have any obligation to the Company or to the other Members or to any creditor or other Person to restore such negative balance during the existence of the Company, upon dissolution or termination of the Company or otherwise, except to the extent required by the Act.

Section 9.07 Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the provisions of Section 5.07, Section 5.08, Section 10.02, Section 11.09 and Section 11.10 shall survive the termination of the Company.

45

ARTICLE X

LIABILITY AND INDEMNIFICATION

Section 10.01 Liability of Members.

(a) No Member and no Affiliate, manager, member, employee or agent of a Member shall be liable for any debt, obligation or liability of the Company or of any other Member or have any obligation to restore any deficit balance in its Capital Account solely by reason of being a Member of the Company, except to the extent required by the Act.

(b) This Agreement is not intended to, and does not, create or impose any duty (including any fiduciary duty) on any of the Members (other than the Managing Member in its capacity as such) hereto or on their respective Affiliates. Further, notwithstanding any other provision of this Agreement or any duty otherwise existing at law or in equity, the parties hereto agree that no Member (other than the Managing Member, in its capacity as such, as set forth in Section 3.06) shall, to the fullest extent permitted by law, have any duties (including fiduciary duties) to any other Member or to the Company, and in doing so, the parties recognize, acknowledge and agree that their duties and obligations to one another and to the Company are only as expressly set forth in this Agreement; provided, however, that each Member shall have the duty to act in accordance with the implied contractual covenant of good faith and fair dealing.

(c) To the extent that, at law or in equity, any Member has duties (including fiduciary duties) and liabilities relating thereto to the Company, to another Member or to another Person who is a party to or is otherwise bound by this Agreement, the Members (other than the Managing Member in its capacity as such) acting under this Agreement will not be liable to the Company, to any such other Member or to any such other Person who is a party to or is otherwise bound by this Agreement, for their good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Member otherwise existing at law or in equity, are agreed by the Members to replace to that extent such other duties and liabilities of the Members relating thereto.

(d) The Managing Member may consult with legal counsel, accountants and financial or other advisors selected by it, and any act or omission taken by the Managing Member on behalf of the Company or in furtherance of the interests of the Company in good faith in reliance upon and in accordance with the advice of such Person as to matters the Managing Member reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion or advice, and the Managing Member will be fully protected in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care.

Section 10.02 Indemnification.

(a) Exculpation and Indemnification. Notwithstanding any other provision of this Agreement, whether express or implied, to the fullest extent permitted by law, no Indemnitee shall be liable to the Company or any Member for any act or omission in relation to the Company or this Agreement or any transaction contemplated hereby taken or omitted by an Indemnitee in good faith and in the reasonable belief that such act or omission was in the best interests of the Company. To the fullest extent permitted by law, as the same exists or hereafter be amended (but in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the Company to provide prior to such amendment), the Company shall indemnify any Indemnitee who was or is made or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Company or otherwise), whether civil,

46

criminal, administrative, arbitrative or investigative, and whether formal or informal (hereinafter a “Proceeding”), including appeals, by reason of his or her or its status as an Indemnitee or by reason of any action alleged to have been taken or omitted to be taken by an Indemnitee in such capacity, from and against all loss and liability suffered and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by such Indemnitee in connection with such action, suit or proceeding, including appeals; provided that such Indemnitee shall not be entitled to indemnification hereunder if, but only to the extent that, such Indemnitee’s conduct constituted fraud, bad faith, gross negligence or willful misconduct. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to indemnify an Indemnitee in connection with any action, suit or proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member, and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent. The indemnification of an Indemnitee of the type identified in clause (e) of the definition of Indemnitee shall be secondary to any and all indemnification to which such Indemnitee is entitled from the relevant other Person (including any payment made to such Indemnitee under any insurance policy issued to or for the benefit of such Person or Indemnitee) (the “ Primary Indemnification”), and will only be paid to the extent the Primary Indemnification is not paid and/or does not provide coverage (e.g., a self -insured retention amount under an insurance policy). No such Person shall be entitled to contribution or indemnification from or subrogation against the Company. The indemnification of any other Indemnitee shall, to the extent not in conflict with such policy, be secondary to any and all payment to which such Indemnitee is entitled from any relevant insurance policy issued to or for the benefit of the Company or any Indemnitee. For the avoidance of doubt, this Agreement shall not affect the indemnification and advancement of rights provided pursuant to the Existing Agreement in favor of any Person relating to proceedings arising out of actions or omissions occurring in whole or in part prior to the effectiveness of this Agreement.

(b) Advancement of Expenses. To the fullest extent permitted by law, the Company shall promptly pay reasonable expenses (including attorneys’ fees) incurred by any Indemnitee in appearing at, participating in or defending any Proceeding in advance of the final disposition of such Proceeding, including appeals, upon presentation of an undertaking on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Section 10.02 or otherwise. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to pay expenses of an Indemnitee in connection with any Proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent.

(c) Unpaid Claims. If a claim for indemnification (following the final disposition of such Proceeding) or advancement of expenses under this Section 10.02 is not paid in full within thirty (30) days after a written claim therefor by any Indemnitee has been received by the Company, such Indemnitee may file proceedings to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Company shall have the burden of proving that such Indemnitee is not entitled to the requested indemnification or advancement of expenses under applicable Law.

(d) Insurance. To the fullest extent permitted by law, the Company may purchase and maintain insurance on behalf of any person described in Section 10.02(a) against any liability asserted against such person, whether or not the Company would have the power to indemnify such person against such liability under the provisions of this Section 10.02 or otherwise.

(i) In the event of any payment by the Company under this Section 10.02, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee from any relevant other Person or under any insurance policy issued to or for the benefit of the Company, such relevant other Person, or any Indemnitee. Each Indemnitee agrees to execute all papers required and take all action necessary to secure such rights, including the execution of such documents as are necessary to enable the Company to bring suit to enforce any such rights in accordance with the terms of such insurance policy or other relevant document. The Company shall pay or reimburse all expenses actually and reasonably incurred by the Indemnitee in connection with such subrogation.

(ii) The Company shall not be liable under this Section 10.02 to make any payment of amounts otherwise indemnifiable hereunder (including, but not limited to, judgments, fines and amounts paid in settlement, and excise taxes with respect to an employee benefit plan or penalties) if and to the extent that the applicable Indemnitee has otherwise actually received such payment under this Section 10.02 or any insurance policy, contract, agreement or otherwise.

(e) Non-Exclusivity of Rights. The provisions of this Section 10.02 shall be applicable to all actions, claims, suits or proceedings made or commenced after the date of this Agreement, whether arising from acts or omissions to act occurring before or after its adoption. The provisions of this Section 10.02 shall be deemed to be a contract between the Company and each person entitled to indemnification under this Section 10.02 (or legal representative thereof) who serves in such capacity at any time while this Section 10.02 and the relevant provisions of applicable Law, if any, are in effect, and any amendment, modification or repeal hereof shall not affect any rights or obligations then existing with respect to any state of facts or any action, suit or proceeding then or theretofore existing, or any action, suit or proceeding thereafter brought or threatened based in whole or in part on any such state of facts. If any provision of this Section 10.02 shall be found to be invalid or limited in application by reason of any law or regulation, it shall not affect the validity of the remaining provisions hereof. The rights of indemnification provided in this Section 10.02 shall neither be exclusive of, nor be deemed in limitation of, any rights to which any person may otherwise be or become entitled or permitted by contract, this Agreement or as a matter of law, both as to actions in such person’s official capacity and actions in any other capacity, it being the policy of the Company that indemnification of any person whom the Company is obligated to indemnify pursuant to Section 10.02(a) shall be made to the fullest extent permitted by law.

(f) ARTICLE EIGHT of the Pubco Charter shall apply mutatis mutandis to this Agreement as if it were incorporated herein.

(g) (i) For purposes of this Article X, (x) “Affiliate” shall mean (A) in respect of a member of the Board of Directors, any Person that, directly or indirectly, is controlled by such member of the Board of Directors (other than the Company and any entity that is controlled by the Company), (B) in respect of any of the Stockholder Parties, a Person that, directly or indirectly, is controlled by any of the Stockholder Parties, controls any of the Stockholder Parties or is under common control with any of the Stockholder Parties and shall include any principal, member, director, partner, stockholder, officer, employee or other representative of any of the foregoing (other than the Company and any entity that is controlled by the Company) and (C) in respect of the Company, any Person that, directly or indirectly, is controlled by the Company and (y) “Person” shall mean any individual, corporation, general or limited partnership, limited liability company, joint venture, trust, association or any other entity.

(ii) For the purposes of this Article, “control,” including the terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting stock, by contract, or otherwise. A person who is the owner of 20% or more of the outstanding voting stock of a corporation, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary. Notwithstanding the foregoing, a presumption of control shall not apply where such person holds voting stock, in good faith and not for the purpose of circumventing this Section (F) of Article X, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group have control of such entity.

(iii) For purposes of this Section 10.02, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan.

(iv) This Section 10.02 shall not limit the right of the Company, to the extent and in the manner permitted by law, to indemnify and to advance expenses to, and purchase and maintain insurance on behalf of, persons other than persons described in Section 10.02(a).

If an amendment, supplement, waiver or modification has been approved in accordance with this Agreement, such amendment, supplement, waiver or modification shall be adopted and effective with respect to all Members. Upon obtaining such approvals as may be required by this Agreement, and without further action or execution on the part of any other Member or other Person, any amendment, supplement, waiver or modification to this Agreement may be implemented and reflected in a writing executed solely by the Managing Member and the other Members shall be deemed a party to and bound by such amendment, supplement, waiver or modification.

53

(b) No failure or delay by any party in exercising any right, power or privilege hereunder (other than a failure or delay beyond a period of time specified herein) shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law.

(c) The Managing Member may, in its sole discretion, unilaterally amend this Agreement on or before the effective date of the final regulations to provide for (i) the election of a safe harbor under Proposed Treasury Regulation Section 1.83-3(l) (or any similar provision) under which the fair market value of a Company interest (or interest in an entity treated as a partnership for U.S. federal income tax purposes) that is transferred is treated as being equal to the liquidation value of that interest, (ii) an agreement by the Company and each of its Members to comply with all of the requirements set forth in such regulations and Notice 2005 -43 (and any other guidance provided by the Internal Revenue Service with respect to such election) with respect to all Company interests (or interest in an entity treated as a partnership for U.S. federal income tax purposes) transferred in connection with the performance of services while the election remains effective, (iii) the allocation of items of income, gains, deductions and losses required by the final regulations similar to Proposed Treasury Regulations Sections 1.704-1(b)(4)(xii)(b) and (c), 1.704-1(b)(2)(iv)(b)(1) and any other related amendments.

Section 11.13 No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their permitted assigns and successors and nothing herein, express or implied, is intended to or shall confer upon any other Person or entity, any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement (other than pursuant to Section 10.02 hereof); provided, however that each employee, officer, director, agent or indemnitee of any Person who is bound by this Agreement or its Affiliates is an intended third party beneficiary of Section 11.10 and shall be entitled to enforce its rights thereunder.
