Section 2.2 Name. The name of the Company is “LAREDO PETROLEUM, LLC” and all Company business must be conducted in that name or such other name or names that comply with Law and as the Board may select.

Section 2.3 Registered Office; Registered Agent; Principal Office; Other Offices.

The registered office of the Company required by the Act to be maintained in Delaware shall be the office of the initial registered agent named in the Certificate or such other office (which need not be a place of business of the Company) as the Board may designate in the manner provided by Law. The registered agent of the Company in Delaware shall be the initial registered agent named in the Certificate or such other Person or Persons as the Board may designate in the manner provided by Law. The principal office of the Company shall be at such place as the Board may designate. The Company may have such other offices as the Board may designate.

Section 2.4 Purposes. The purposes of the Company are to carry on any lawful business, purpose or activity for which limited liability companies may be formed under the Act, including to engage indirectly through subsidiaries in the acquisition of, exploration for and exploitation and development of, oil and natural gas primarily in the United States and to engage in such other activities incidental or ancillary thereto as the Board deems necessary or advisable, all upon the terms and conditions set forth in this Agreement. For the avoidance of doubt, the Company does not intend to engage in any activities that could result in the recognition of unrelated business taxable income within the meaning of Code Section 512 by any Member or holder of Units or Membership Interests by reason of its ownership or holding of Units or Membership Interests.

Section 2.5 Foreign Qualification. The Board shall cause the Company to comply with all requirements necessary to qualify the Company as a foreign limited liability company in foreign jurisdictions if that jurisdiction requires qualification. At the request of the Board, each Member shall execute, acknowledge, swear to and deliver all certificates and other instruments conforming with this Agreement that are necessary or appropriate to qualify, continue and terminate the Company as a foreign limited liability company in all such jurisdictions in which the Company may conduct business, provided, that no Member shall be required to file any general consent to service of process or to qualify as a foreign corporation, limited liability company, partnership or other entity in any jurisdiction in which it is not already so qualified.

Section 2.6 Term. The Company commenced upon the effectiveness of the Certificate and shall have a perpetual existence, unless and until it is dissolved and terminated in accordance with Article 12.

Section 2.7 No State Law Partnership. The Members intend that the Company not be a partnership (including a limited partnership) or joint venture, and that no Member be a partner or joint venturer of any other Member, for any purposes other than federal and state tax purposes, and this Agreement may not be construed to suggest otherwise.

Section 2.8 Title to Company Assets. Title to the Company’s assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Company as an entity. Title to any or all of the Company assets may be held in the name of the Company or one or more of its Subsidiaries or one or more nominees, as the Board may determine. All Company assets shall be recorded as the property of the Company in its books and records, irrespective of the name in which record title to such Company assets is held.

The Preferred Units shall initially be divided into two series of units referred to as “Series A-l Preferred Units” and “Series A-2 Preferred Units”. The Profits Units shall initially be divided into four series of units referred to as “Series B Units”, “Series C Units”, “Series D Units” and “Series E Units”. The Company is authorized to issue up to 60,000,000 units designated as “Series A-l Preferred Units”, 48,000,000 units designated as “Series A-2 Preferred Units”, 16,923,077 units designated as “Series B Units”, 8,791,209 units designated as “Series C Units”, 13,538,462 units designated as “Series D Units” and 7,032,967 units designated as “Series E Units”. The Series A-2 Preferred Units shall have a Designated Value of $1.25; provided, however, that such Units shall not constitute “profits interests” as described in Sections 3.2(d), (e), (f) and (g).

(b) Series A-l Preferred Units. The Company has issued 60,000,000 Series A-l Preferred Units at a purchase price of $5.00 per Series A-l Preferred Unit pursuant to the Series A-l Unit Subscription Agreement.

(c) Series A-2 Preferred Units. The Company may issue, from time to time, an aggregate of up to 48,000,000 Series A-2 Preferred Units at a purchase price of $6.25 per Series A-2 Preferred Unit pursuant to the Unit Subscription Agreement.

(d) Series B Units.

(i) The Company may issue an aggregate of up to 16,923,077 Series B Units pursuant to Restricted Unit Agreements. The Series B Units may be vested (the “Vested Series B Units”) or unvested (the “Unvested Series B Units”). Unvested Series B Units shall vest or remain unvested in the manner and subject to the conditions set forth in the applicable Restricted Unit Agreement under which such Units were granted. The Company shall not issue Series B Units to any Person who has not executed and delivered to the Company the applicable Restricted Unit Agreement, together with one or more of the following agreements selected by the Board: (i) a non-competition and confidentiality agreement, substantially in the form attached hereto as Exhibit H, or in the form as otherwise approved by the Board, (ii) a confidentiality, non-solicitation and non- disparagement agreement in the form approved by the Board, or (iii) an employment agreement in the form approved by the Board. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, in the event of a Change of Control, or upon the occurrence of a Liquidation Event, (A) the Compensation Committee, in its sole discretion, may allocate and cause the Company to issue all authorized but unissued Series B Units (not including any previously issued Series B Units that have been redeemed by or forfeited to the Company) and (B) all outstanding Series B Units shall automatically become Vested Series B Units.

(ii) The Series B Units are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the IRS or other applicable law). Accordingly, the capital account associated with each Series B Unit at the time of its issuance shall be equal to zero dollars ($0.00). The Company and the holders of Series B Units shall file all federal income tax returns consistent with such characterization.

(iii) Of the aggregate authorized number of Series B Units, 6,288,000 have been designated by the Board as “Series B-l Units” and issued on or prior to the date hereof with a Designated Value of $0.00, and 2,329,000 have been designated by the Board as “Series B-2 Units” and issued on or prior to the date hereof with a Designated Value of $1.25. The Company may from time to time designate and issue additional series of Series B Units (up to the number of authorized but unissued Series B Units), each of which shall be designated by a sequential number (e.g., Series B-3, Series B-4, etc.). The Board shall designate a “Designated Value” applicable to each such additional series of Series B Units to the extent necessary to cause such Units to constitute “profits interests” as provided in Section 3.2(d)(ii) above, but not less than $0.00 (taking into account the adjustments to Book Value contemplated in clause (ii) of subparagraph (b) of the definition thereof). The Designated Value for each such additional series of Series B Units shall equal not less than the amount that would, in the reasonable determination of the Board, be distributed with respect to each Series A-l Preferred Unit if, immediately prior to the issuance of such additional series, the assets of the Company were sold for their fair market value and the proceeds (net of any liabilities of the Company) were distributed pursuant to Section 6.1(c).

(e) Series C Units.

(i) The Company may issue an aggregate of up to 8,791,209 Series C Units pursuant to Restricted Unit Agreements. The Series C Units may be vested (the “Vested Series C Units”) or unvested (the “Unvested Series C Units”). Unvested Series C Units shall vest or remain unvested in the manner and subject to the conditions set forth in the applicable Restricted Unit Agreement under which such Units were granted. The Company shall not issue Series C Units to any Person who has not executed and delivered to the Company the applicable Restricted Unit Agreement, together with one or more of the following agreements selected by the Board: (i) a non-competition and confidentiality agreement, substantially in the form attached hereto as Exhibit H, or in the form as otherwise approved by the Board, (ii) a confidentiality, non-solicitation and non- disparagement agreement in the form approved by the Board, or (iii) an employment agreement in the form approved by the Board. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, in the event of a Change of Control, or upon the occurrence of a Liquidation Event, (A) the Compensation Committee, in its sole discretion, may allocate and cause the Company to issue all authorized but unissued Series C Units (not including any previously issued Series C Units that have been redeemed by or forfeited to the Company) and (B) all outstanding Series C Units shall automatically become Vested Series C Units.

(ii) The Series C Units are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the IRS or other applicable law). Accordingly, the capital account associated with each Series C Unit at the time of its issuance shall be equal to zero dollars ($0.00). The Company and the holders of Series C Units shall file all federal income tax returns consistent with such characterization.

(iii) Of the aggregate authorized number of Series C Units, 7,780,000 have been designated by the Board as “Series C-l Units” and issued on or prior to the date hereof with a Designated Value of $10.00. The Company may from time to time designate and issue additional series of Series C Units (up to the number of authorized but unissued Series C Units), each of which shall be designated with a sequential number (e.g. Series C-2, Series C-3, etc.). The Board shall designate a “Designated Value” applicable to each such additional series of Series C Units to the extent necessary to cause such Units to constitute “profits interests” as provided in Section 3.2(e)(ii) above, but not less than $10.00 (taking into account the adjustments to Book Value contemplated in clause (ii) of subparagraph (b) of the definition thereof). The Designated Value for each such additional series of Series C Units shall equal not less than the sum of $10.00 plus the amount that would, in the reasonable determination of the Board, be distributed with respect to each Series A-l Preferred Unit if, immediately prior to the issuance of such additional series, the assets of the Company were sold for their fair market value and the proceeds (net of any liabilities of the Company) were distributed pursuant to Section 6.1(c).

(f) Series C Units.

(i) The Company may issue an aggregate of up to 13,538,462 Series D Units pursuant to Restricted Unit Agreements. The Series D Units may be vested (the “Vested Series D Units”) or unvested (the “Unvested Series D Units”). Unvested Series D Units shall vest or remain unvested in the manner and subject to the conditions set forth in the applicable Restricted Unit Agreement under which such Units were granted. The Company shall not issue Series D Units to any Person who has not executed and delivered to the Company the applicable Restricted Unit Agreement, together with one or more of the following agreements selected by the Board: (i) a non-competition and confidentiality agreement, substantially in the form attached hereto as Exhibit H, or in the form as otherwise approved by the Board, (ii) a confidentiality, non-solicitation and non- disparagement agreement in the form approved by the Board, or (iii) an employment agreement in the form approved by the Board. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, in the event of a Change of Control, or upon the occurrence of a Liquidation Event, (A) the Compensation Committee, in its sole discretion, may allocate and cause the Company to issue all authorized but unissued Series D Units (not including any previously issued Series D Units that have been redeemed by or forfeited to the Company) and (B) all outstanding Series D Units shall automatically become Vested Series D Units.

(ii) The Series D Units are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the IRS or other applicable law). Accordingly, the capital account associated with each Series D Unit at the time of its issuance shall be equal to zero dollars ($0.00). The Company and the holders of Series D Units shall file all federal income tax returns consistent with such characterization.

(iii) Of the aggregate authorized number of Series D Units, a number of Series D Units shall be designated by the Board as “Series D-l Units.” The Company may from time to time designate and issue additional series of Series D Units (up to the number of authorized but unissued Series D Units) each of which shall be designated with a sequential number (e.g., Series D-2, Series D-3, etc.). The Board shall designate a “Designated Value” applicable to the Series D-l Units and to each such additional series of Series D Units to the extent necessary to cause such Units to constitute “profits interests” as provided in Section 3.2(f)(ii) above, but not less than $1.25 (taking into account the adjustments to Book Value contemplated in clause (ii) of subparagraph (b) of the definition thereof). The Designated Value for each such additional series of Series D Units shall equal not less than the sum of $1.25 plus the amount that would, in the reasonable determination of the Board, be distributed with respect to each Series A-l Preferred Unit if, immediately prior to the issuance of such additional series, the assets of the Company were sold for their fair market value and the proceeds (net of any liabilities of the Company) were distributed pursuant to Section 6.1(c).

(g) Series E Units.

(i) The Company may issue an aggregate of up to 7,032,967 Series E Units pursuant to Restricted Unit Agreements. The Series E Units may be vested (the “Vested Series E Units”) or unvested (the “Unvested Series E Units”). Unvested Series E Units shall vest or remain unvested in the manner and subject to the conditions set forth in the applicable Restricted Unit Agreement under which such Units were granted. The Company shall not issue Series E Units to any Person who has not executed and delivered to the Company the applicable Restricted Unit Agreement, together with one or more of the following agreements selected by the Board: (i) a non-competition and confidentiality agreement, substantially in the form attached hereto as Exhibit H, or in the form as otherwise approved by the Board, (ii) a confidentiality, non-solicitation and non- disparagement agreement in the form approved by the Board, or (iii) an employment agreement in the form approved by the Board. Notwithstanding anything to the contrary in this Agreement or the other Transaction Documents, in the event of a Change of Control, or upon the occurrence of a Liquidation Event, (A) the Compensation Committee, in its sole discretion, may allocate and cause the Company to issue all authorized but unissued Series E Units (not including any previously issued Series E Units that have been redeemed by or forfeited to the Company) and (B) all outstanding Series E Units shall automatically become Vested Series E Units.

(ii) The Series E Units are intended to constitute “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the IRS or other applicable law). Accordingly, the capital account associated with each Series E Unit at the time of its issuance shall be equal to zero dollars ($0.00). The Company and the holders of Series E Units shall file all federal income tax returns consistent with such characterization.

(iii) Of the aggregate authorized number of Series E Units, a number of Series E Units shall be designated by the Board as “Series E-l Units”. The Company may from time to time designate and issue additional series of Series E Units (up to the number of authorized but unissued Series E Units), each of which shall be designated by a sequential number (e.g. Series E-2, Series E-3, etc.). The Board shall designate a “Designated Value” applicable to the Series E-l Units and to each such additional series of Series E Units to the extent necessary to cause such Units to constitute “profits interests” as provided in Section 3.2(g)(ii) above, but not less than $13.75 (taking into account the adjustments to Book Value contemplated in clause (ii) of subparagraph (b) of the definition thereof). The Designated Value for each such additional series of Series E Units shall equal not less than the sum of $13.75 plus the amount that would, in the reasonable determination of the Board, be distributed with respect to each Series A-l Preferred Unit if, immediately prior to the issuance of such additional series, the assets of the Company were sold for their fair market value and the proceeds (net of any liabilities of the Company) were distributed pursuant to Section 6.1(c).

(h) Units shall constitute “securities” governed by Article 8 of the applicable version of the Uniform Commercial Code, as amended from time to time after the date hereof.

(i) Profits Units that have been redeemed by or forfeited to the Company may be reissued subject to the requisite Board approval, Requisite Approval and other terms and conditions of this Agreement, including in the case of redeemed Profits Units the respective requirements of Section 3.2(d)(iii), Section 3.2(e)(iii), Section 3.2(f)(iii) and Section 3.2(g)(iii). For the avoidance of doubt, any Profits Units that have been redeemed by or forfeited to the Company may be reissued in accordance with this Agreement with a Designated Value that is different from the Designated Value of the Profits Units so redeemed or forfeited, subject to the provisions of Section 3.2(d)(iii), Section 3.2(e)(iii), Section 3.2(f)(iii) and Section 3.2(g)(iii), as applicable.

Section 3.3 No Other Persons Deemed Members. Unless admitted to the Company as a Member as provided in this Agreement, no Person (including an assignee of rights with respect to Units or Membership Interests or a transferee of Units or Membership Interests, whether voluntary, by operation of law or otherwise) shall be, or shall be considered, a Member. The Company may elect to deal only with Persons so admitted as Members (including their duly authorized representatives). Any distribution by the Company to the Person shown on the Company’s records as a Member or to its legal representatives, shall relieve the Company of all liability to any other Person who may have an interest in such distribution by reason of any Disposition by the Member or for any other reason.

Section 3.4 No Resignation. A Member may not take any action to Resign as a Member voluntarily, and a Member may not be removed involuntarily, prior to the dissolution and winding up of the Company, other than as a result of a permitted Disposition of all of such Member’s Units in accordance with Article 7 and each of the transferees of such Units being admitted as a Substituted Member in accordance therewith. A Member will cease to be a Member only in the manner described in Section 3.5 and Article 12.

Section 3.5 Admission of Additional Members and Substituted Members and Creation of Additional Units.

(a) Authority. Subject to the limitations set forth in this Article 3 and in Article 7 and subject to Section 8.5, the Company may admit Additional Members and Substituted Members to the Company and may also issue additional Units or create and issue such additional classes or series of Units or Membership Interests (or securities convertible into or exercisable or exchangeable for a Unit or other Membership Interest), having such designations, preferences and relative, participating or other special rights, powers and duties as the Board shall determine, including: (i) the right of any such class or series of Units or Membership Interests to share in the Company’s distributions; (ii) the allocation to any such class or series of Units or Membership Interests of Profits (and all items included in the computation thereof) or Losses (and all items included in the computation thereof); (iii) the rights of any such class or series of Units or Membership Interests upon dissolution or liquidation of the Company; and (iv) the right of any such class or series of Units or Membership Interests to vote on matters relating to the Company and this Agreement. Upon the issuance pursuant to and in accordance with this Article 3 of any class or series of Units or Membership Interests, the Board may, subject to Section 13.5, amend any provision of this Agreement, and authorize any Person to execute, acknowledge, deliver, file and record, if required, such documents, to the extent necessary or desirable to reflect the

admission of any additional Member to the Company or the authorization and issuance of such class or series of Units or Membership Interests (or securities convertible into or exercisable or exchangeable for a Unit or other Membership Interest), and the related rights and preferences thereof.

(b) Conditions. No Additional Member or Substituted Member shall be admitted to the Company unless and until all applicable conditions of this Section 3.5 and Article 7 are satisfied. Without limiting the generality of the foregoing, no Disposition or issuance of Units or Membership Interests otherwise permitted or required by this Agreement shall be effective, no Member shall have the right to substitute a transferee as a Member in its place with respect to any Units or Membership Interests acquired by such transferee in any Disposition and no purchaser of newly issued Units or Membership Interests from the Company shall be deemed to be a Member, in each case unless and until any such transferee or purchaser who is not already a party to this Agreement (and such transferee’s or such purchaser’s spouse, if applicable) shall execute and deliver to the Company an Addendum Agreement in the form attached as Exhibit C (an “Addendum Agreement”) and such other documents or instruments as may be required in the Company’s reasonable judgment to effect the admission.

(c) Rights and Obligations of Additional Members and Substituted Members. A transferee of Units or Membership Interests who has been admitted as an Additional Member or as a Substituted Member or a purchaser of newly issued Units or Membership Interests from the Company who has been admitted as an Additional Member in accordance with this Section 3.5 shall have all the rights and powers and be subject to all the restrictions and liabilities under this Agreement relating to a Member holding Units.

(d) Date of Admission as Additional or Substituted Member. Admission of an Additional Member or Substituted Member shall become effective on the date such Person’s name is recorded on the books and records of the Company. Upon the admission of an Additional Member or Substituted Member, (i) the Company shall amend Schedule I or II, as applicable, to reflect the name and address of, and number and class of Units held by, such Additional Member or Substituted Member and to eliminate or adjust, if necessary, the name, address and interest of the predecessor of such Substituted Member (such revisions to be presented to the Board no later than at the next regular meeting of the Board) and (ii) to the extent of the Disposition to such Substituted Member, the Disposing Member shall be relieved of its obligations under this Agreement. Any Member who shall Dispose of all of such Member’s Units or Membership Interests in one or more Dispositions permitted pursuant to this Section 3.5 and Article 7 (where each transferee was admitted as a Substituted Member) shall cease to be a Member as of the last date on which all transferees are admitted as Substituted Members, provided, that, notwithstanding anything to the contrary herein, such Member shall not be relieved of any liabilities incurred by such Member pursuant to the terms and conditions of this Agreement prior to the time such Member Disposes of any Units or Membership Interests or ceases to be a Member hereunder.

Section 3.6 No Liability of Members. Except as otherwise provided under the Act, the debts, liabilities, contracts and other obligations of the Company (whether arising in contract, tort or otherwise) shall be solely the debts, liabilities, contracts and other obligations of the

Company, and no Member in its capacity as such shall be liable personally (a) for any debts, liabilities, contracts or any other obligations of the Company, except to the extent and under the circumstances set forth in any non-waivable provision of the Act or in any separate written instrument signed by the applicable Member, or (b) for any debts, liabilities, contracts or other obligations of any other Member. No Member shall have any responsibility to restore any negative balance in its Capital Account or to contribute to or in respect of the liabilities or obligations of the Company or to return distributions made by the Company, except as expressly provided herein (including pursuant to Section 12.3) or required by any non-waivable provision of the Act; provided, however, that each Committed Member shall be responsible for its failure to make required Capital Contributions in accordance with this Agreement. The agreement set forth in the immediately preceding sentence shall be deemed to be a compromise with the consent of all of the Members for purposes of §18-502(b) of the Act. However, if any court of competent jurisdiction orders, holds or determines that, notwithstanding the provisions of this Agreement, any Member is obligated to restore any such negative balance, make any such contribution or make any such return, such obligation shall be the obligation of such Member and not of any other Person.

Section 3.7 Spouses of Members. Spouses of the Members that are natural persons do not become Members as a result of such marital relationship. Each spouse of a Member shall be required to execute a Spousal Agreement in the form of Exhibit B to evidence his or her agreement and consent to be bound by the terms and conditions of this Agreement as to his or her interest, whether as community property or otherwise, if any, in the Units owned by such Member.

(d) Purchase Entirely For Own Account. The Units to be acquired by such Member will be acquired for investment for such Member’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof; such Member has no present intention of selling, granting any participation in, or otherwise distributing the same; and such Member does not have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Units.

ARTICLE 5

CAPITAL CONTRIBUTIONS

Section 5.1 Prior Contributions. As of the Effective Date, the Members listed on Schedule II have made Capital Contributions to the Company in exchange for Series A-l Preferred Units as set forth opposite such Member’s name in Schedule II, if any, pursuant to the Series A-l Unit Subscription Agreement.

Section 5.2 Additional Commitments. Subject to the terms and conditions hereof and of the Unit Subscription Agreement:

(a) Each Member listed on Schedule II with a dollar amount set forth under column (2) opposite such Member’s name (each, a “Committed Member”) agrees to make, upon the issuance of Capital Calls meeting the requirements of this Article 5, additional cash Capital Contributions (“Commitment Contributions”) in an amount not to exceed in aggregate the amount set forth opposite the name of such Committed Member under column (2) on Schedule II (the “Additional Commitment” of such Committed Member) in exchange for Series A-2 Preferred Units. The amount, at a particular time, by which a Committed Member’s Additional Commitment exceeds the total amount of the Commitment Contributions previously made by such Committed Member pursuant to this Article 5 shall be the “Remaining Commitment” of

such Committed Member at such time. For the avoidance of doubt, in no event shall any Member’s Additional Commitment or Remaining Commitment be increased without such Member’s prior written consent and in no event shall any Member be obligated at any time to make Capital Contributions in excess of its Remaining Commitment as of the time of such Capital Call less any amounts required to be funded pursuant to then outstanding Capital Calls.

(b) The Management Committed Members shall have the option to increase their Additional Commitments in accordance with this Section 5.2(a). During the 31-day period beginning on December 1 and ending on December 31 of each of the years 2008, 2009 and 2010 (each such 31-day period a “Management Committed Member Exercise Period”), each Management Committed Member shall have the right, but not the obligation (a “Management Committed Member Option”), by delivery of written notice to the Company prior to the expiration of such Management Committed Member Exercise Period, to increase his Additional Commitment by the amount specified in such notice provided that the aggregate amount specified in all notices delivered by such Management Committed Member pursuant to this Section 5.2(a) shall not exceed 100% of such Management Committed Member’s Total Commitment as of the Effective Date and shall not exceed the Remaining Commitment of Warburg Pincus X as of the end of the applicable 31-day period. The delivery of a notice of election under this Section 5.2(a) by a Management Committed Member shall constitute an irrevocable commitment to fund such increased Additional Commitment. Upon receipt by the Company from a Management Committed Member of a timely delivered and properly executed notice of election, the Additional Commitment of such Management Committed Member shall be increased dollar-for-dollar by the amount specified in such notice and the Additional Commitment of Warburg Pincus X shall be decreased dollar-for-dollar (which decrease shall be allocated pro rata between the entities comprising Warburg Pincus X) by the amount specified in such notice. If a Management Committed Member exercises a Management Committed Member Option pursuant to this Section 5.2(a), the first Capital Call following exercise of such a Management Committed Member Option shall be apportioned so that after such Management Committed Member makes the Commitment Contributions required by it pursuant to the Call Notice related to such Capital Call (i) the quotient (expressed as a percentage) obtained by dividing (a) the total amount of Commitment Contributions such Management Committed Member will have funded immediately after such Capital Call by (b) the total amount of Commitment Contributions all Committed Members will have funded immediately after such Capital Call will be equal to (ii) the quotient (expressed as a percentage) obtained by dividing (x) such Management Committed Member’s Total Commitment (calculated by including the increase in such Management Committed Member’s Additional Commitment as a result of the exercise of such Management Committed Member Option) by (y) the aggregate Total Commitments of all Committed Members. Notwithstanding the foregoing, the Board, in its sole discretion, shall be entitled, by delivery of written notice to the Management Committed Members on or prior to the December 1 of each Management Committed Member Exercise Period, to postpone the Management Committed Members’ right to exercise of any Management Committed Member Option for a period not to exceed 150 days from the expiration of the Management Committed Member Exercise Period if the Company is contemplating any material transaction, such notice to include a general explanation of the reason for such postponement. Following the expiration of any such postponement period, each Management Committed Member shall have the right to exercise his postponed Management Committed Member Option

in accordance with this Section 5.2(a), provided that the Management Committed Member Exercise Period for such Management Committed Member Option shall begin on the first day after the expiration of such postponement period and shall end on the 31st day after the expiration of such postponement period. All increases and decreases in Additional Commitments made pursuant to this Section 5.2(a) shall be effective as of the expiration date of the applicable Management Committed Member Exercise Period (giving effect to any postponement of a Management Committed Member Option).

(c) In connection with any adjustment to the Additional Commitments of the Committed Members in connection with the reallocation of Future Series A-2 Preferred Units to employees of the Company or its Subsidiaries (including members of the Management Team) or non-employee Managers of the Company (each such employee or Manager, a “Reallocated Committed Member”) pursuant to Section 3.1 of the Unit Subscription Agreement, the Board, in its sole discretion, may elect to apportion the first Capital Call following such adjustment in a manner such that after such Reallocated Committed Member makes the Commitment Contributions required by it pursuant to the Call Notice related to such Capital Call (i) the quotient (expressed as a percentage) obtained by dividing (a) the total amount of Commitment Contributions such Reallocated Committed Member will have funded immediately after such Capital Call by (b) the total amount of Commitment Contributions all Committed Members will have funded immediately after such Capital Call will be equal to (ii) the quotient (expressed as a percentage) obtained by dividing (x) such Reallocated Committed Member’s Total Commitment by (y) the aggregate Total Commitments of all Committed Members.

(d) The Remaining Commitment of each Committed Member shall be reduced to zero upon the consummation of a Qualified Public Offering and no Management Committed Member shall thereafter be entitled to increase its Additional Commitment.

(e) If a Committed Member is an employee of the Company or any of its Subsidiaries and such employment ceases for any reason, then, except as otherwise agreed by the Board, such Committed Member’s Remaining Commitment shall immediately be reduced to zero and such Committed Member shall have no right to increase its Additional Commitment. If the Remaining Commitment of a Committed Member is reduced to zero pursuant to the preceding sentence, the Board shall have the authority to reassign the amount of such forfeited Remaining Commitment to one or more other Committed Members who consent in writing to such reassignment in such amounts as are determined by the Board in its sole discretion.

(f) A Member whose Remaining Commitment is zero shall have no further right or obligation to make Commitment Contributions to the Company except as may be required with respect to a Defaulting Member pursuant to Section 5.4.

Section 5.3 Capital Calls.

(a) The Company may from time to time prior to the expiration of the Takedown Period call for Commitment Contributions from the Committed Members (each, a “Capital Call”) for project development activities, working capital and acquisitions, and each Committed Member, subject to the terms and conditions hereof and the Unit Subscription Agreement, shall

make its Commitment Contribution in response to each Capital Call. No Capital Call may be made for an aggregate amount less that $5,000,000, except that if the aggregate amount of remaining Commitment Contributions is less than $5,000,000 a Capital Call may be made for the aggregate amount of remaining Commitment Contributions. After giving effect to the provisions of Sections 5.2(a) and 5.2(c), if applicable, each Capital Call shall be apportioned ratably among all Committed Members based on, and such Capital Call may not exceed, their respective Remaining Commitments less any amounts required to be funded pursuant to then outstanding Capital Calls as of the date of such Capital Call. Each Capital Call shall be made pursuant to a call notice, substantially in the form attached hereto as Exhibit G-l (each a “Call Notice”), executed by the Chief Executive Officer and another Officer authorized by the Board and (other than an Investor Call Right Call Notice) approved by (i) the Board and (ii) within five days after such Board Approval, by Requisite Approval as provided in Section 8.5. Each Call Notice shall specify (i) in reasonable detail the purpose of such Capital Call, and (ii) the amount of the Commitment Contributions to be made by each Committed Member pursuant to such Capital Call. Each Call Notice shall be delivered to the Committed Members. A Call Notice may provide for the Commitment Contribution to be made in a single contribution or in multiple contributions over time. The Board shall have the authority (but only with, and conditioned upon, prior written Requisite Approval) to withdraw any Call Notice at any time prior to the time that funding is required thereunder.

(b) Upon the exercise of the Investor Call Right (as defined in the Unit Subscription Agreement), the Company shall issue a Call Notice, which shall be in the form of Exhibit G-2 (the “Investor Call Right Call Notice”), setting forth the Commitment Contributions to be made by the Committed Members.

(c) Each Committed Member shall make the Commitment Contribution required by it pursuant to a Call Notice (other than a Call Notice that provides for periodic funding) within 30 days after such Call Notice is delivered to the Committed Members. Each Committed Member shall make the Commitment Contribution required by it pursuant to a Call Notice which provides for periodic funding, on or prior to the periodic dates set forth in such Call Notice; provided, however, that the Committed Members shall not be required to make the initial funding under any such Call Notice prior to the 30th day after such Call Notice is received by the Committed Members. The time periods specified in this Section 5.3(c) for making Commitment Contributions shall be subject to extension to the extent necessary to pursue any required regulatory approvals, as further described below. Upon payment of any Commitment Contribution, and upon the terms and conditions of the Unit Subscription Agreement, the Company shall issue to such Committed Member a number of Series A-2 Preferred Units equal to the amount of such Commitment Contribution, divided by $6.25.

(d) If any regulatory approval, including the filing and the expiration of any waiting period under the Hart Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”), is required prior to the issuance of any Series A-2 Preferred Units, the Company shall not issue such Series A-2 Preferred Units, and the Committed Member to whom such Series A-2 Preferred Units are to be issued shall not be required to make any Commitment Contribution with respect thereto, until such approval has been obtained (or in the case of the HSR Act, such filing has been completed and such waiting period has expired). The Company and the Members shall use

their commercially reasonable efforts to comply promptly with all applicable regulatory requirements. The Company shall bear all documented and reasonable fees and expenses, including all filing fees, incurred by it or such Committed Member in connection with such compliance. In no event shall any Member be deemed to have become a Defaulting Member as a result of its inability, as reasonably determined by such Member, to make a Commitment Contribution prior to such compliance.

(e) Notwithstanding the foregoing, no Member shall be obligated to fund a Commitment Contribution in the event of a Bankruptcy of the Company or the commencement of a Liquidation Event with respect to the Company.

(f) Notwithstanding anything to the contrary in this Agreement, no Member that is not an Accredited Investor at the time of any funding of a Commitment Contribution shall be entitled to fund such Commitment Contribution.

(g) Not less than five days prior to the required funding date of each Commitment Contribution required to be made pursuant to a Call Notice that provides for periodic funding, the Company shall deliver to each Committed Member an officers’ certificate signed by the Chief Executive Officer and the Chief Financial Officer certifying that to the actual knowledge of the Management Team since the date of the most recent prior Commitment Contribution, no event has occurred that (including with the passage of time or the giving of notice or both) could reasonably be expected to result in a material adverse effect on the business, condition (financial or otherwise), properties, assets, results of operations or liabilities of the Company and its Subsidiaries, taken as a whole (the “MAE Bringdown Certificate”). Notwithstanding anything to the contrary in this Agreement, each Member’s obligation to fund a Commitment Contribution required pursuant to a Call Notice that provides for periodic funding shall be suspended on the fifth day prior to the applicable funding date if the Company has failed to deliver the MAE Bringdown Certificate, unless waived by Requisite Approval, and such obligation shall remain suspended until reinstated by the Board with Requisite Approval.

Section 5.4 Defaulting Members. A Committed Member that fails to make a Capital Contribution as prescribed in Section 5.3 (a “Defaulted Contribution”) and does not cure such failure within five business days after notice from the Company of such failure (a “Defaulting Member”) shall be in default of this Agreement but shall remain fully obligated to make such Capital Contribution to the Company, shall cease to have the rights (but shall remain subject to the obligations, as applicable) set forth in Sections 7.4, 7.6 and 7.8, and shall be subject to all such other rights and remedies as the Company may have against such Committed Member, including rights and remedies arising from its breach of this Agreement and rights and remedies the Company may have at law or in equity. Furthermore, if the Defaulting Member is a Committed Member (other than a member of the Warburg Pincus Group), at the election of the Company, the Company may take any one or more of the following remedial actions (to the extent not mutually exclusive with any other remedy described in this Section 5.4):

(a) cause such Defaulting Member to (i) sell such Member’s Preferred Units at a price equal to 75% of such Member’s Capital Contributions that were made in exchange for Preferred Units made prior to the default (net of expenses, Losses and prior distributions) to the

Company or a designee or designees of the Company and (ii) forfeit such Member’s Profits Units to the Company or a designee or designees of the Company, unless such Member cures such failure within 30 days after notice from the Company of such failure;

(b) charge interest on such Member’s Defaulted Contributions at (i) a rate that is the lower of (A) 14% per annum, compounded quarterly or (B) the maximum rate permitted under applicable law or (ii) such other lower rate determined by the Board;

(c) loan such Member an amount equal to such Member’s Defaulted Contributions and charge interest on such amount at a rate that is the lower of (i) 14% per annum, compounded quarterly or (ii) the maximum rate permitted under applicable law;

(d) reduce such Defaulting Member’s Remaining Commitment (including the Remaining Commitment related to the Defaulted Contribution) to zero and permit each Committed Member that is not a Defaulting Member to increase its Additional Commitment by its pro rata portion of such Defaulting Member’s Remaining Commitment (including the Remaining Commitment related to the Defaulted Contribution) pursuant to this Section 5.4(d). In such event, the Company shall notify each Committed Member who is not a Defaulting Member of the aggregate amount of the Remaining Commitment (including all Defaulted Contributions) of such Defaulting Member (the “Defaulted Commitments”). Each non- Defaulting Committed Member will then have the right to elect to fund a pro-rata percentage of all Defaulted Commitments based on the relative Remaining Commitments of the non- Defaulting Committed Members less any amounts required to be funded by such Committed Members pursuant to then outstanding Capital Calls. To exercise the right to fund Defaulted Commitments, a non-Defaulting Committed Member must notify the Company in writing within five days after the receipt of notice from the Company that such non-Defaulting Committed Member elects to fund its pro-rata percentage of the Defaulted Commitments. Such election by a non-Defaulting Committed Member will automatically increase its Remaining Commitment on a dollar-for-dollar basis by the amount of its pro rata percentage of such Defaulted Commitments. If there are any Defaulted Commitments remaining after such five day notice period, the Warburg Pincus Group may elect to increase its Remaining Commitment on a dollar-for-dollar basis by the amount of such remaining Defaulted Commitments. The delivery of a notice of election under this Section 5.4(d) by a non-Defaulting Committed Member shall constitute an irrevocable commitment to fund such Defaulted Commitments. Unless otherwise determined by the Board, the Defaulted Commitment shall not include the amount of any unexercised option to increase such Defaulting Member’s Additional Commitment pursuant to Section 5.2(a) and a Defaulting Member shall have no further right, if any, to elect to increase such Defaulted Member’s Additional Commitment pursuant to Section 5.2(a) upon becoming a Defaulting Member; or

(e) pursue any other rights and remedies the Company may have against such Member.

Section 5.5 Return of Contributions. A Member is not entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Account or its Capital Contributions. An unrepaid Capital Contribution is not a liability of the Company or

of any Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contributions.

Section 5.6 Capital Account. A Capital Account shall be established and maintained for each Member in accordance with the requirements of Treasury Regulations Section 1.704- l(b)(2)(iv). Each Member’s Capital Account (a) shall be increased by (i) the amount of money contributed by such Member to the Company, (ii) the Book Value of property contributed by such Member to the Company (net of liabilities secured by the contributed property that the Company is considered to assume or take subject to under Code Section 752) and (iii) allocations to such Member of Profits and any other items of income or gain allocated to such Member, and (b) shall be decreased by (i) the amount of money distributed to such Member by the Company, (ii) the Book Value of property distributed to such Member by the Company (net of liabilities secured by the distributed property that such Member is considered to assume or take subject to under Code Section 752), and (iii) allocations to such Member of Losses and any other items of loss or deduction allocated to such Member. The Capital Accounts shall also be increased or decreased to reflect a revaluation of Company property pursuant to paragraph (b) of the definition of Book Value. On the transfer of all or part of a Member’s Units, the Capital Account of the transferor that is attributable to the transferred Units shall carry over to the transferee Member in accordance with the provisions of Treasury Regulation Section 1.704- l(b)(2)(iv)(l). A Member that has more than one class of Units shall have a single Capital Account that reflects all such Units; provided, however, that the Capital Accounts shall be maintained in such manner as will facilitate a determination of the portion of each Capital Account attributable to each series of Preferred Units and Profits Units.

Section 5.7 Advances by Members. If the Company does not have sufficient cash to pay its obligations, then with the approval of the Board, any or all of the Members may (but will have no obligation to) advance all or part of the needed funds to or on behalf of the Company, which advances will constitute a loan from such Member or Members to the Company, will bear interest and be subject to such other terms and conditions as agreed between such Member or Members and the Company and will not be deemed to be a Capital Contribution.

ARTICLE 6

DISTRIBUTIONS AND ALLOCATIONS

Section 6.1 Distributions.

(a) Each distribution made by the Company, regardless of the source or character of the assets to be distributed, shall be made in accordance with this Article 6 and applicable Law.

(b) Prior to making distributions pursuant to Section 6.1(c), on each Tax Distribution Date, the Company shall, subject to the availability of funds, distribute to each Member in cash an amount equal to such Member’s Assumed Tax Liability, if any. “Tax Distribution Date” means any date that is five business days prior to the date on which estimated income tax payments are required to be made by calendar year individual taxpayers and each due date for the income tax return of an individual calendar year taxpayer (without regard to extensions).

“Assumed Tax Liability” of each Member means an amount equal to (i) the cumulative amount of federal, state and local income taxes (including any applicable estimated taxes) determined taking into account the character of income and loss allocated as it affects the applicable tax rate that the Board estimates would be due from such Member as of such Tax Distribution Date, (x) assuming such Member were an individual who earned solely the items of income, gain, deduction, loss, and/or credit allocated to such Member pursuant to Section 6.2, (y) after taking proper account of loss carryforwards available to individual taxpayers resulting from losses allocated to the Members by the Company, to the extent not taken into account in prior periods, and (z) assuming that such Member is subject to tax at the highest applicable rate, reduced by (ii) all previous distributions made pursuant to this Section 6.1. The Board will make its determination of the Assumed Tax Liability of (i) the holders of Preferred Units, assuming that each such holder is a resident of New York, New York, and (ii) the holders of Profits Units, based upon its good faith determination of the jurisdiction in which such holders are subject to tax with respect to the income of the Company (or if no such determination is made, in the same manner as determined for the holders of Preferred Units). Distributions pursuant to this Section 6.1(b) shall be treated as an advance distribution under Section 6.1(c) and shall offset future distributions that such holder of Units would otherwise be entitled to receive pursuant to Section 6.1(c). If on a Tax Distribution Date there are not sufficient funds on hand to distribute to each Member the full amount of such Member’s Assumed Tax Liability, distributions pursuant to this Section 6.1(b) shall be made to the Members to the extent of the available funds in proportion to each Member’s Assumed Tax Liability, and the Company shall make future distributions as soon as funds become available to pay the remaining portion of such Member’s Assumed Tax Liability. Notwithstanding the foregoing and for the avoidance of doubt, the Members agree that the Company shall not be required to make distributions to a Member pursuant to this Section 6.1(b) to the extent that such Member realizes income in connection with the issuance of Profits Units to such Member, the forfeiture of Profits Units by such Member in accordance with the Transaction Documents or the repurchase of Profits Units from such Member in accordance with the Transaction Documents.

(c) The Board shall have sole discretion to determine the timing of any other distribution and the aggregate amounts available for such distribution. Each such other distribution made by the Company, regardless of the source or character of the assets to be distributed, shall be made in the following order of priority:

(i) First, with respect to the holders of outstanding Preferred Units, in proportion to the Preferred Unit Preference Amount of each outstanding Preferred Unit, until the entire Preferred Unit Preference Amount of all outstanding Preferred Units has been reduced to zero;

(ii) Second, until the $1.25 Threshold is met, (A) the Series A-l Unit Percentage Interest of such distribution shall be distributed to the holders of the Series A- 1 Preferred Units in proportion to their Series A-l Unit Sharing Ratios, and (B) the Series B Unit Percentage Interest of such distribution shall be distributed to the holders of Series B Units in proportion to their Series B Unit Sharing Ratios;

(iii) Third, until the $10.00 Threshold is met, (A) the Series A-l Unit Percentage Interest of such distribution shall be distributed to the holders of the Series A- 1 Preferred Units in proportion to their Series A-l Unit Sharing Ratios, (B) the Series B Unit Percentage Interest of such distribution shall be distributed to the holders of Series B Units in proportion to their Series B Unit Sharing Ratios, (C) the Series A-2 Unit Percentage Interest of such distribution shall be distributed to the holders of Series A-2 Preferred Units in proportion to their Series A-2 Unit Sharing Ratios, and (D) the Series D Unit Percentage Interest of such distribution shall be distributed to the holders of Series D Units in proportion to their Series D Unit Sharing Ratios;

(iv) Fourth, until the $13.75 Threshold is met, (A) the Series A-l Unit Percentage Interest of such distribution shall be distributed to the holders of the Series A- 1 Preferred Units in proportion to their Series A-l Unit Sharing Ratios, (B) the Series B Unit Percentage Interest of such distribution shall be distributed to the holders of Series B Units in proportion to their Series B Unit Sharing Ratios, (C) the Series A-2 Unit Percentage Interest of such distribution shall be distributed to the holders of Series A-2 Preferred Units in proportion to their Series A-2 Unit Sharing Ratios, (D) the Series D Unit Percentage Interest of such distribution shall be distributed to the holders of Series D Units in proportion to their Series D Unit Sharing Ratios, and (E) the Series C Unit Percentage Interest of such distribution shall be distributed to the holders of Series C Units in proportion to their Series C Unit Sharing Ratios; and

(v) Thereafter, (A) the Series A-l Unit Percentage Interest of such distribution shall be distributed to the holders of the Series A-l Preferred Units in proportion to their Series A-l Unit Sharing Ratios, (B) the Series B Unit Percentage Interest of such distribution shall be distributed to the holders of Series B Units in proportion to their Series B Unit Sharing Ratios, (C) the Series A-2 Unit Percentage Interest of such distribution shall be distributed to the holders of Series A-2 Preferred Units in proportion to their Series A-2 Unit Sharing Ratios, (D) the Series D Unit Percentage Interest of such distribution shall be distributed to the holders of Series D Units in proportion to their Series D Unit Sharing Ratios, (E) the Series C Unit Percentage Interest of such distribution shall be distributed to the holders of Series C Units in proportion to their Series C Unit Sharing Ratios, and (F) the Series E Unit Percentage Interest of such distribution shall be distributed to the holders of Series E Units in proportion to their Series E Unit Sharing Ratios.

(d) Notwithstanding the foregoing provisions of Section 6.1 (c), all amounts otherwise distributable pursuant to this Agreement (other than Section 6.1(b)) with respect to each Unvested Profits Unit shall be retained by the Company (collectively, the “WithheldAmounts”). Prior to making any distribution pursuant to Section 6.1(c) or Section 12.2(c), but subject to the first sentence of this Section 6.1(d) and to Section 6.1(e), (i) the Withheld Amounts with respect to each Profits Unit that has become a Vested Profits Unit shall be distributed to the holder of such Profits Unit and (ii) the Withheld Amounts with respect to each Unvested Profits Unit that has been forfeited or cancelled shall be available for distribution pursuant to Section 6.1(c) or Section 12.2(c).

(e) Notwithstanding the foregoing, from and after the Original Execution Date, 100% of the amount otherwise distributable to the holders of Profits Units pursuant to Section 6.1(c) or Section 6.1(d) (or such lesser percentage as approved by the Board) shall be retained by the Company (collectively, the “Retained Amounts”) until the Retained Amounts equal not less than the aggregate amount that would be required to satisfy the sum of the Profits Units Clawback Amount with respect to each holder of Profits Units in the event that all then Remaining Commitments of all Committed Members were fully funded and no further distributions were made pursuant to this Section 6.1 (such sum, the “Potential Clawback Amount’). If at any time, whether as a result of distributions made pursuant to this Section 6.1 or a reduction in the aggregate Remaining Commitments of the Committed Members, the Retained Amounts exceed the Potential Clawback Amount, then the Company shall distribute all Retained Amounts in excess of the Potential Clawback Amount to the holders of the outstanding Profits Units to whom such Retained Amounts would have been distributed had they not been retained pursuant to this Section 6.1(e).

(f) All distributions made under this Section 6.1 shall be made to the holders of record of the applicable Units on the record date established by the Board or, in the absence of any such record date, to the holders of the applicable Units on the date of the distribution.

(g) Except for distributions pursuant to Section 6.1(b), the Company may distribute securities in kind. The fair market value of securities distributed in kind shall be determined by the Board.

(h) The Company is authorized to withhold from distributions, or with respect to allocations, to the holders of Units and to pay over to any federal, state, local or foreign government any amounts required to be so withheld pursuant to the Code or any provisions of applicable Law. For all purposes under this Agreement, any amount so withheld shall be treated as actually distributed to the holder with respect to which such amount was withheld.

(i) An illustration of the distribution provisions set forth in Section 6.1(c) is attached hereto as Exhibit I.

Section 6.2 Allocations of Profits and Losses.

(a) General Profit and Loss Allocations. For each taxable period of the Company, Profits and Losses and all items included in the computation thereof shall be allocated among the Members in such a manner that, as of the end of each taxable period and to the extent possible, the Capital Account of each Member shall be equal to the excess (which may be negative) of:

(i) the amount that would be distributed to such Member under this Agreement if (x) all Company assets were sold for cash equal to their Book Values at the end of such taxable period, (y) all Company liabilities were satisfied in cash according to their terms (limited, with respect to each nonrecourse liability, to the Book Value of the assets securing such liability) and all Members’ obligations to make contributions to the Company upon such a hypothetical sale and dissolution of the Company were satisfied in

full in cash, and (z) the net proceeds thereof (after satisfaction of such liabilities) were distributed in full pursuant to Section 6.1, over

(ii) the sum of (x) the amount, if any, that such Member would be obligated to contribute to the capital of the Company as determined immediately after the hypothetical sale described in Section 6.2(a)(i), (y) such Member’s share of the Minimum Gain determined pursuant to Section 6.2(b)(i) computed immediately prior to the hypothetical sale described in Section 6.2(a)(i), and (z) such Member’s share of Member Nonrecourse Debt Minimum Gain determined pursuant to Section 6.2(b)(ii) computed immediately prior to the hypothetical sale described in Section 6.2(a)(i);

provided that Losses shall not be allocated to a Member pursuant to this Section 6.2(a) to the extent that such allocation would cause such Member to have a deficit balance in its Adjusted Capital Account (or increase any existing deficit balance in its Adjusted Capital Account) at the end of such taxable period. Losses in excess of the limitation set forth in this Section 6.2(a) shall be allocated to the Members who do not have deficit balances in their Adjusted Capital Accounts in proportion to their relative Adjusted Capital Account balances.

(b) Regulatory Allocations. Notwithstanding any other provisions of this Section 6.2, the following special allocations shall be made for each taxable period:

(i) Notwithstanding any other provision of this Section 6.2, if there is a net decrease in Minimum Gain during any taxable period, each Member shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), (g)(2) and (j)(2)(i). For purposes of this Section 6.2(b), each Member’s Capital Account shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.2(b) with respect to such taxable period. This Section 6.2(b)(i) is intended to comply with the minimum gain chargeback requirement in Treasury Regulation Section 1.704- 2(f) and shall be interpreted consistently therewith.

(ii) Notwithstanding the other provisions of this Section 6.2 (other than Section 6.2(b)(i) above), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any taxable period, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Section 1.704-2(i)(4) and (j)(2)(ii). For purposes of this Section 6.2(b), each Member’s Adjusted Capital Account balance shall be determined, and the allocation of income and gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.2(b), other than Section 6.2(b)(i) above, with respect to such taxable period. This Section 6.2(b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Except as provided in Sections 6.2(b)(i) and 6.2(b)(ii) above, a Member who unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-l(b)(2)(ii)(d)(4), (5) or (6) shall be allocated items of income and gain (consisting of a pro rata portion of each item of income, including gross income, and gain for the taxable year) in an amount and manner sufficient to eliminate any deficit balance in such Member’s Adjusted Capital Account as quickly as possible provided that an allocation pursuant to this Section 6.2(b)(iii) shall be made only if and to the extent that such Member would have a negative Adjusted Capital Account after all allocations provided for in this Article 6 have been tentatively made as if this Section 6.2(b)(iii) were not in this Agreement. This Section 6.2(b)(iii) is intended to constitute a qualified income offset under Treasury Regulation Section 1.704-1 (b)(2)(ii)(d) and shall be interpreted consistently therewith.

(iv) In the event that any Member has a deficit balance in its Adjusted Capital Account at the end of any taxable year, such Member shall be allocated items of Company income and gain in the amount of such deficit as quickly as possible; provided that an allocation pursuant to this Section 6.2(b)(iv) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Article 6 have been tentatively made as if Section 6.2(b)(iii) and this Section 6.2(b)(iv) were not in this Agreement.

(v) To the extent an adjustment to the adjusted tax basis of any Company property pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Treasury Regulation Section 1.704-l(b)(2)(iv)(m)(2) or 1.704-l(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts as the result of a distribution to any Member in complete liquidation of such Member’s Membership Interest, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be allocated to the Members in accordance with Treasury Regulation Section 1.704-l(b)(2)(iv)(m)(2) if such Section applies, or to the Member to whom such distribution was made if Treasury Regulation Section 1.704-l(b)(2)(iv)(m)(4) applies.

(vi) If, as a result of an exercise of a noncompensatory option or warrant, a Capital Account reallocation is required under Proposed Treasury Regulation Section 1.704-l(b)(2)(iv)(s)(3) (as such Proposed Treasury Regulation may be amended or modified, including upon the issuance of temporary or final Treasury Regulations), the Company shall make corrective allocations pursuant to Proposed Treasury Regulation Section 1.704-l(b)(4)(x), as such Proposed Treasury Regulation may be amended or modified, including upon the issuance of temporary or final Treasury Regulations.

(vii) If any holder of Management Units or Profits Units forfeits all or a portion of such Units, the Company shall make forfeiture allocations to such holder in the manner and to the extent required by Proposed Treasury Regulation Section 1.704-1(b)(4)(xii) (as such Proposed Treasury Regulation may be amended or modified, including upon the issuance of temporary or final Treasury Regulations).

(viii) Nonrecourse Deductions for any taxable period shall be allocated to the Members holding Preferred Units or Series B Units in accordance with their relative Nonrecourse Deduction Shares.

(ix) Member Nonrecourse Deductions for any taxable period shall be allocated 100% to the Member that bears the Economic Risk of Loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Members in accordance with the ratios in which they share such Economic Risk of Loss.

(c) Curative Allocations. The Regulatory Allocations are intended to comply with certain requirements of Treasury Regulation Sections 1.704-1(b) and 1.704-2. The Regulatory Allocations may be inconsistent with the manner in which the Members intend to divide distributions from the Company. Accordingly, the Board is authorized to divide other items of income, gain, loss and deduction of the Company among the Members, so that the net amount of the Regulatory Allocations and the Curative Allocations to each Member is zero (0). The Board will have discretion to accomplish this result in any reasonable manner that is consistent with Code Section 704 and the corresponding Treasury Regulations.

Section 6.3 Income Tax Allocations.

(a) Except as provided in this Section 6.2, each item of income, gain, loss and deduction of the Company for federal income tax purposes shall be allocated among the Members in the same manner as such items are allocated for book purposes under Section 6.1.

(b) In accordance with Code Section 704(c) and the applicable Treasury Regulations thereunder, income, gain, loss and deduction with respect to any property contributed to the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company for Federal income tax purposes and its initial Book Value. In the event the Book Value of any property is adjusted pursuant to clause (b) or (d) of the definition of Book Value, subsequent allocations of income, gain, loss and deduction with respect to such property shall take account of any variation between the adjusted basis of such property for Federal income tax purposes and its Book Value in the same manner as under Code Section 704(c) and the applicable Treasury Regulations thereunder. For purposes of such allocations, the Company shall use the allocation method described in Treasury Regulation Section 1.704-3 selected by the Board.

(c) All items of income, gain, loss, deduction and credit allocated to the Members in accordance with the provisions hereof and basis allocations recognized by the Company for federal income tax purposes shall be determined without regard to any election under Section 754 of the Code which may be made by the Company; provided, however, such allocations, once made, shall be adjusted as necessary or appropriate to take into account the adjustments permitted by sections 734 and 743 of the Code.

(d) If any deductions for depreciation, cost recovery or depletion are recaptured as ordinary income upon the sale or other disposition of Company properties, the ordinary income character of the gain from such sale or disposition shall be allocated among the Members in the same ratio as the deductions giving rise to such ordinary income character were allocated.

Section 6.4 Other Allocation Rules. All items of income, gain, loss, deduction and credit allocable to Units that may have been transferred shall be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as the owner of such Units, without regard to the results of Company operations during any particular portion of that calendar year and without regard to whether cash distributions were made to the transferor or the transferee during that calendar year; provided, however, that this allocation must be made in accordance with a method permissible under Code Section 706 and the regulations thereunder. If any Units are Disposed of or redeemed in compliance with the provisions of this Agreement, all distributions with respect to which the record date is before the date of such Disposition or redemption shall be made to the Disposing Member, and all distributions with respect to which the record date is after the date of such Disposition, in the case of a Disposition other than a redemption, shall be made to the transferee.

ARTICLE 7

DISPOSITIONS OF UNITS; PREEMPTIVE RIGHTS; IPO CONVERSION

Section 7.1 Restrictions on Dispositions of Units.

(a) Disposition of Units otherwise permitted or required by this Agreement may only be made in compliance with federal and state securities laws, including the Securities Act and the rules and regulations thereunder, and the Act.

(b) For so long as the Company is a partnership for U.S. federal income tax purposes, in no event may any Disposition of any Units by any Member be made if such Disposition is effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code or if such Disposition would otherwise result in the Company being treated as a “publicly traded partnership,” as such term is defined in Section 7704(b) of the Code and the regulations promulgated thereunder.

(c) Dispositions of Units may only be made in strict compliance with all applicable terms of this Agreement, and any purported Disposition of Units that does not so comply with all applicable provisions of this Agreement shall be null and void and of no force or effect, and the Company shall not recognize or be bound by any such purported Disposition and shall not effect any such purported Disposition on the transfer books of the Company or Capital Accounts of the Members. The Members agree that the restrictions contained in this Article 7 are fair and reasonable and in the best interests of the Company and the Members.

(d) Each Member that is an entity that was formed for the sole or principal purpose of directly or indirectly acquiring Membership Interests or Units or an entity whose principal asset is its Membership Interests or Units, or direct or indirect interests in Membership Interests or

Units, agrees that it will not permit Dispositions of Capital Stock in such Member in a single transaction or series of related transactions if such Dispositions collectively would result in Capital Stock in such Member representing a majority of the economic or voting interests in such Member being owned or Controlled by a Person or Persons that do not own or Control Capital Stock in such Member as of the date that such Member became a Member unless such Member requires such Dispositions of such Capital Stock to be treated as a full Disposition of Membership Interests or Units by such Member hereunder.

Section 7.2 Additional Restrictions on Dispositions of Profits Units and Management Units.

(a) No Disposition of Unvested Profits Units may be made except (i) to a Permitted Transferee in accordance with Section 7.3, (ii) in connection with an IPO Exchange, (iii) in connection with a Drag-Along Transaction or (iv) to the Company in accordance with the redemption provisions of the applicable Restricted Unit Agreement or this Agreement.

(b) No Disposition of Management Units or Vested Profits Units may be made except (i) to a Permitted Transferee in accordance with Section 7.3, (ii) in connection with an IPO Exchange, (iii) after the fifth anniversary of the Effective Date, subject to Section 7.4, (iv) in connection with a Drag-Along Transaction, (v) after the fifth anniversary of the Effective Date, in connection with the exercise of inclusion rights pursuant to Section 7.6 or (vi) to the Company or to any other holder or holders of Profits Units, in each case if such Disposition is either approved by the Compensation Committee or in accordance with the redemption or repurchase provisions of the applicable Restricted Unit Agreement or this Agreement.

(c) Notwithstanding anything to the contrary contained herein, no Disposition of Management Units or Vested Profits Units may be made to any Person that is a Potential Competitor of, or an adverse party to, the Company, as reasonably determined by the Board, except pursuant to Section 7.5 or in connection with the permitted exercise of inclusion rights pursuant to Section 7.6.

Section 7.3 Permitted Dispositions.

(a) In addition to any Disposition expressly permitted by this Section 7.3, any holder of any Preferred Units may Dispose of such Units to any Person, subject to the provisions of Section 7.1 and to the applicable provisions of Section 7.2(b), Section 7.2(b), Section 7.4 and Section 7.6. Notwithstanding the foregoing and for the avoidance of doubt, any member of the Warburg Pincus Group may Dispose of any Units to one or more Affiliates of Warburg Pincus LLC, subject only to the provisions of Section 7.1.

(b) Any holder of any Units may Dispose of such Units by way of gift to a Permitted Transferee of such holder; provided, however, that (i) such Permitted Transferee shall not be entitled to make any further Dispositions in reliance upon this Section 7.3(b), except for a Disposition of such acquired Units back to such original holder or to another Permitted Transferee of such holder or a Person to whom such transfer is permitted under Section 7.2, and (ii) such Permitted Transferee must assume all of the obligations of the original holder of the

Units and agree to comply with the provisions of the applicable Restricted Unit Agreement and this Agreement, as applicable.

(c) Notwithstanding anything to the contrary in this Section 7.3, a Member may not make a Disposition of Units to a Permitted Transferee if such Disposition has as a purpose the avoidance of or is otherwise undertaken in contemplation of avoiding the restrictions on Dispositions in this Agreement (it being understood that the purpose of this Section 7.3(c) is to prohibit the Disposition of Units to a Permitted Transferee followed by a change in the relationship between the transferor and the Permitted Transferee (or a change of Control of such transferor or Permitted Transferee) after the Disposition with the result and effect that the transferor has indirectly made a Disposition of Units by using a Permitted Transferee, which Disposition would not have been directly permitted under this Section 7.3 had such change in such relationship occurred prior to such Disposition).

(d) In connection with any Disposition of Preferred Units (including Management Units) that a Committed Member is permitted to make under this Article 7, such Committed Member may also transfer all or a portion of such Member’s Remaining Commitment with the approval of the Board.

Section 7.4 Rights of First Refusal.

(a) If any holder of any Preferred Units (other than any member of the Warburg Pincus Group) or any Vested Profits Units receives a bona fide written offer from any Third Party (a “Third Party Offer”) for the purchase of all or a part of such holder’s Preferred Units or Vested Profits Units and such holder desires to accept and is permitted to effect such proposed Disposition pursuant to Section 7.2, such holder (the “Offeror Holder”) shall deliver written notice of such Third Party Offer (the “Notice of Right of First Refusal”) to the Company no less than 30 days prior to the date of the proposed Disposition. The date that the Notice of Right of First Refusal is received by the Company shall constitute the “First Refusal Notice Date.” Within five days after receipt of the Notice of Right of First Refusal by the Company, the Company shall send a copy of the Notice of Right of First Refusal along with a letter indicating the First Refusal Notice Date to each Institutional Investor that holds Preferred Units (other than the Offeror Holder and any such holder that is a Defaulting Member) (each, a “ROFR Holder”). The notice shall set forth the name of the Third Party (including, if such information is not publicly available, information about the identity of the Third Party), the number and class or series of Preferred Units or Vested Profits Units to be sold (the “Offered Units,” which shall not include Units to be sold that are not Preferred Units or Vested Profits Units), the price per Unit for the Offered Units (the “Offer Price”), all details of the payment terms and all other terms and conditions of the proposed Disposition. A Third Party Offer may not contain provisions related to any property of the Offeror Holder other Preferred Units or Vested Profits Units held by the Offeror Holder, and the Offer Price shall be expressed only in terms of cash (in U.S. dollars). The Offer Price per Offered Unit may differ in order to reflect differences in the Preferred Unit Preference Amounts and Designated Values with respect to the Preferred Units that are Offered Units and differences in rights to distributions pursuant to Section 6.1(c), Designated Values, Withheld Amounts and Retained Amounts, if any, with respect to the Vested Profits Units that are Offered Units. Any Third Party Offer for Preferred Units or Vested Profits Units not

satisfying the terms of this Section 7.4 (e.g., a Third Party Offer in which not all of the proposed consideration is cash or a Third Party Offer to purchase property other than Preferred Units or Vested Profits Units or a Third Party Offer that is not bona fide) may not be made unless otherwise expressly permitted pursuant to the other provisions of this Article 7.

(b) Each ROFR Holder shall have the right to purchase up to that number of the Offered Units (calculated separately with respect to each series of Preferred Units that are Offered Units and each series of Vested Profits Units that are Offered Units, and, within each series of Preferred Units and Vested Profits Units, divided as evenly as practicable among the purchasing ROFR Holders with respect to any Preferred Units that are Offered Units with differing Preferred Unit Preference Amounts and Designated Values and any Vested Profits Units that are Offered Units that have differing rights to distributions pursuant to Section 6.1(c), Designated Values, Withheld Amounts and Retained Amounts) equal to the product of (A) the applicable number of Offered Units and (B) a fraction (the “Proportionate Share”), the numerator of which shall be the number of Preferred Units held by such ROFR Holder and the denominator of which shall be the total number of Preferred Units held by all ROFR Holders. Within 25 days after the First Refusal Notice Date, each ROFR Holder may deliver a written notice to the Offeror Holder, the Company and each other ROFR Holder of its election to purchase such Offered Units. To the extent any ROFR Holder does not elect to purchase its full Proportionate Share of such Offered Units or fails to deliver a notice within the applicable period, each ROFR Holder that has elected to purchase its full Proportionate Share shall be entitled, by delivering written notice to the Offeror Holder and the Company within five days following the end of such 25-day period (such fifth day, the “Offer Expiration Date”), to purchase up to all of the remaining Offered Units. If there is an oversubscription, the oversubscribed amount shall be allocated among the ROFR Holders fully exercising their rights to purchase such remaining Offered Units pro rata based on the number of Preferred Units owned by each fully electing ROFR Holder relative to the outstanding Preferred Units held by all fully electing ROFR Holders. The delivery of a notice of election under this Section 7.4 shall constitute an irrevocable commitment to purchase such Offered Units. If the ROFR Holders shall have elected to purchase all but not less than all of the Offered Units, the Company shall thereafter set a reasonable place and time for the closing of the purchase and sale of the Offered Units, which shall be not less than 30 days nor more than 90 days after the First Refusal Notice Date (subject to extension to the extent necessary to pursue any required regulatory approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) unless otherwise agreed by all of the parties to such transaction.

(c) The purchase price and terms and conditions for the purchase of the Offered Units pursuant to this Section 7.4 shall be the price and terms and conditions set forth in the applicable Third Party Offer; provided, that the Offeror Holder shall at a minimum make customary representations and warranties concerning (i) such Offeror Holder’s valid title to and ownership of the Offered Units, free and clear of all liens, claims and encumbrances (excluding those arising under applicable securities laws), (ii) such Offeror Holder’s authority, power and right to enter into and consummate the sale of the Offered Units, (iii) the absence of any violation, default or acceleration of any agreement to which such Offeror Holder is subject or by which its assets are bound as a result of the agreement to sell and the sale of the Offered Units, and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or

notifications required to be obtained or made by such Offeror Holder in connection with the sale of the Offered Units. The Offeror Holder also agrees to execute and deliver such instruments and documents and take such actions, including obtaining all applicable approvals and consents and making all applicable notifications and filings, as the purchasing ROFR Holders may reasonably request in order more effectively to implement the purchase and sale of the Offered Units hereunder. Upon the request of any ROFR Holder, the Company will promptly verify the Preferred Unit Preference Amounts, rights to distributions pursuant to Section 6.1(c), Designated Values, Withheld Amounts and Retained Amounts, if any, with respect to any Offered Units.

(d) Notwithstanding the foregoing, if the ROFR Holders shall not have elected to purchase all of such Offered Units on or prior to the Offer Expiration Date, such ROFR Holders shall not have the right to purchase any of the Offered Units and the Offered Units or any portion thereof may be sold by the Offeror Holder at any time within 90 days after the Offer Expiration Date, subject to the provisions of Section 7.1 and to the applicable provisions of Section 7.2(b). Any such sale shall not be at less than the price or upon terms and conditions more favorable, individually or in the aggregate, to the purchaser than those specified in the Third Party Offer. If any such Offered Units are not so transferred within such 90-day period, the Offeror Holder may not sell any of the Offered Units without again complying in full with the provisions of this Section 7.4.

(e) Notwithstanding anything to the contrary in this Agreement, each member of the Warburg Pincus Group that is a ROFR Holder shall be entitled to assign its right to purchase Offered Units pursuant to this Section 7.4 to any other Person.

(f) Notwithstanding anything to the contrary in this Agreement, at any time after the six-month anniversary of the First Refusal Notice Date with respect to each Third Party Offer, the Company shall be entitled to waive, on behalf of each ROFR Holder, each former ROFR Holder and each of their respective Affiliates, successors and assigns and the members, partners, stockholders, directors, managers, officers, liquidators and employees of each of the foregoing (collectively, the “ROFR Holder Persons”) any and all claims such ROFR Holder Persons have, had or may have or had with respect to any non-compliance or violation of this Section 7.4 by any Person with respect to such Third Party Offer (whether or not any Units were Disposed of pursuant to this Section 7.4), other than any such claim that has been made in writing and delivered to the Company prior to expiration of such six-month anniversary.

Section 7.5 Drag-Along Rights.

(a) At any time the Warburg Pincus Group may propose a Drag-Along Transaction and require all other holders of Units to sell all but not less than all of their Units in accordance with this Section 7.5.

(b) In connection with any such Drag-Along Transaction, all holders of Units entitled to consent thereto shall consent to and raise no objections against the Drag-Along Transaction, and if the Drag-Along Transaction is structured as (i) a merger, conversion, Unit exchange or consolidation of the Company, or a sale of all or substantially all of the assets of the Company, each holder of Units entitled to vote thereon shall vote in favor of the Drag-Along Transaction

and shall waive any appraisal rights or similar rights in connection with such merger, conversion, Unit exchange, consolidation or asset sale, or (ii) a sale of all the Units, each holder of Units shall agree to sell all of his or its Units that are the subject of the Drag-Along Transaction, on the terms and conditions of such Drag-Along Transaction. The holders of Units shall promptly take all necessary and desirable actions in connection with the consummation of the Drag-Along Transaction, including the execution of such agreements and such instruments and other actions reasonably necessary to (A) provide customary representations, warranties, indemnities, and escrow/holdback arrangements relating to such Drag-Along Transaction (subject to Sections 7.5(c)(iv) and 7.5(c)(v) below), in each case to the extent that each other holder of Units is similarly obligated, and (B) effectuate the allocation and distribution of the aggregate consideration upon the Drag-Along Transaction as set forth in Section 7.5(c) below. The holders of Units shall be permitted to sell their Units pursuant to any Drag-Along Transaction without complying with any other provisions of this Article 7.

(c) The obligations of the holders of Units pursuant to this Section 7.5 are subject to the following terms and conditions:

(i) Upon the consummation of the Drag-Along Transaction, each holder of Units shall receive the same proportion of the aggregate consideration from such Drag- Along Transaction that such holder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in Section 6.1 as in effect immediately prior to such Drag-Along Transaction (for the avoidance of doubt, this means that differences in Preferred Unit Preference Amounts and Designated Values with respect to the Preferred Units and differences in Designated Values, Withheld Amounts and Retained Amounts, if any, with respect to Profits Units will be taken into account and that the timing of distributions will be taken into account, including the timing of any distributions of any Withheld Amounts or Retained Amounts), and if a holder of Units receives consideration from such Drag- Along Transaction in a manner other than as contemplated by such rights and preferences or in excess of the amount to which such holder is entitled in accordance with such rights and preferences, then such holder shall take such action as is necessary so that such consideration shall be immediately reallocated among and distributed to the holders of Units in accordance with such rights and preferences;

(ii) if any holder of a series of Units is given an option as to the form and amount of consideration to be received, all holders of Units shall be given the same option; provided, that, the form of consideration per Unit may differ to reflect differences in Preferred Unit Preference Amounts and Designated Values of the Preferred Units and differences in Designated Values, Withheld Amounts and Retained Amounts, if any, with respect to Profits Units;

(iii) the Company shall bear the reasonable, documented costs incurred in connection with any Drag-Along Transaction (costs incurred by or on behalf of any holder of Units for its sole benefit will not be considered costs of the transaction hereunder) unless otherwise agreed by the Company and the acquiror, in which case no holder of Units shall be obligated to make any out-of-pocket expenditure prior to the

consummation of the Drag-Along Transaction (excluding modest expenditures for postage, copies, and the like) and no holder of Units shall be obligated to pay any portion (or, if paid, shall be entitled to be reimbursed by the Company for that portion paid) that is more than its pro rata share (based upon the amount of consideration received, after the payment of all Preferred Unit Preference Amounts) of reasonable expenses incurred in connection with a consummated Drag-Along Transaction;

(iv) no holder of Units shall be required to provide any representations, warranties or indemnities (other than pursuant to an escrow or holdback of consideration proportionate to the amount receivable under this Section 7.5) in connection with the Drag-Along Transaction, other than customary (including with respect to qualifications) several representations, warranties and indemnities concerning (i) such holder’s valid title to and ownership of Units, free and clear of all liens, claims and encumbrances (excluding those arising under applicable securities laws), (ii) such holder’s authority, power and right to enter into and consummate such Drag-Along Transaction, (iii) the absence of any violation, default or acceleration of any agreement to which such holder is subject or by which its assets are bound as a result of the Drag-Along Transaction, and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be obtained or made by such holder in connection with the Drag-Along Transaction (and then only to the extent that each other holder of Units provides similar representations, warranties and indemnities with respect to the Units held by such holder of Units);

(v) no holder of Units shall be obligated in respect of any indemnity obligations in such Drag-Along Transaction for an aggregate amount in excess of the total consideration payable to such holder of Units in such Drag-Along Transaction; and

(vi) if some or all of the consideration received in connection with the Drag- Along Transaction is other than cash, then such consideration shall be deemed to have a dollar value equal to the fair market value of such consideration as determined by the Board in its reasonable judgment.

(d) Notwithstanding anything to the contrary in this Section 7.5, if the consideration proposed to be paid to the holders of Units in a Drag-Along Transaction includes securities with respect to which no registration statement covering the issuance of such securities has been declared effective under the Securities Act, then each of the holders of Units that is not then an Accredited Investor (without regard to Rule 501(a)(4)) may be required (notwithstanding Section 7.5(c)(ii)), at the request and election of the holders of Units that are pursuing a Drag-Along Transaction, to (i) appoint a purchaser representative (as such term is defined in Rule 501 under the Securities Act) reasonably acceptable to such requesting holders or (ii) accept cash in lieu of any securities such non-Accredited Investor would otherwise receive in an amount equal to the fair market value of such securities as determined in the manner set forth in Section 7.5(c)(vi).

(e) The Warburg Pincus Group shall have the right in connection with any such transaction (or in connection with the investigation or consideration of any such potential transaction) to require the Company to cooperate fully with potential acquirors in such

prospective Drag-Along Transaction by taking all customary and other actions reasonably requested by such holders or such potential acquirors, including making the Company’s properties, books and records, and other assets reasonably available for inspection by such potential acquirors, establishing a physical or electronic data room including materials customarily made available to potential acquirors in connection with such processes and making its employees reasonably available for presentations, interviews and other diligence activities, in each case subject to reasonable and customary confidentiality provisions. In addition, the Warburg Pincus Group shall be entitled to take all steps reasonably necessary to carry out an auction of the Company, including selecting an investment bank, providing confidential information (pursuant to confidentiality agreements), selecting the winning bidder and negotiating the requisite documentation. The Company shall provide assistance with respect to these actions as reasonably requested.

Section 7.6 Tag-Along Rights.

(a) Subject to Section 7.4 and Section 7.2, if any Institutional Investor or Institutional Investors (the “Transferors”) desire to Dispose of all or any portion of their respective Preferred Units to a Third Party (the “Tag-Along Transferee”), such Transferors shall offer to include in such proposed Disposition (the “Tag-Along Sale”) a number of Eligible Units owned and designated by any Eligible Seller, in each case in accordance with the terms of this Section 7.6. Notwithstanding the foregoing, this Section 7.6 shall not be applicable to, and the Transferors may Dispose of Preferred Units without complying with any of the provisions of this Section 7.6 in connection with, any Disposition (i) to a Permitted Transferee, (ii) made pursuant to a Drag-Along Transaction, or (iii) made pursuant to an IPO Exchange. The Transferors shall cause the offer from such Tag-Along Transferee (the “Tag-Along Offer”) to be reduced to writing, which writing shall include (x) an offer to purchase or otherwise acquire Eligible Units from the Eligible Sellers as required by this Section 7.6, (y) a time and place designated for the closing of such purchase and (z) the per Unit purchase price proposed to be paid by the Tag-Along Transferee for the Transferors’ Preferred Units in a Tag-Along Sale and the aggregate proceeds expected to be payable in respect of any Profits Units included in such Tag-Along Sale (which proceeds shall be calculated in accordance with Section 7.6(h) below). The per Unit purchase price proposed to be paid by the Tag-Along Transferee may differ in order to reflect differences in the Preferred Unit Preference Amounts and Designated Values with respect to the Preferred Units that are Eligible Units and differences in Designated Values, Withheld Amounts and Retained Amounts with respect to Profits Units that are Eligible Units. Certain capitalized terms that are used in this Section 7.6 are defined in Section 7.6(j) below.

(b) Each of the Preferred Tag Offerees and Profits Series Tag Offerees shall be entitled to request to include certain Eligible Units in such Tag-Along Sale, in each case in accordance with the terms of this Section 7.6; provided, however, that notwithstanding anything to the contrary in this Section 7.6, for each series of Profits Units, the Profits Series Tag Offerees who hold Profits Units of such series shall not be entitled to include, and the Tag-Along Transferee shall not purchase, any Profits Units of such series that are Eligible Units in such Tag-Along Sale unless the aggregate number of the Profits Units of such series that are Eligible Units so included is equal to (i) the aggregate number of Profits Units of such series (including

Unvested and Vested Profits Units of such series) then outstanding multiplied by (ii) the Purchased Preferred Percentage.

(c) The Transferors shall send written notice of such Tag-Along Offer (the “Preferred Inclusion Notice”), together with the Transferor Requested Preferred Percentage, to each of the Preferred Tag Offerees. Each Preferred Tag Offeree shall have the right (a “Preferred Inclusion Right’), exercisable by delivery of notice to the Transferors at any time within 15 days after receipt of the Preferred Inclusion Notice, to request to sell in the Tag-Along Sale a number of Preferred Units equal to the total number of Preferred Units held by such Preferred Tag Offeree multiplied by the Transferor Requested Preferred Percentage. Promptly following such 15-day period, the Transferors shall calculate the number of Requested Preferred Units and the Requested Preferred Tag-Along Percentage.

(d) Promptly following the determination of the Requested Preferred Tag-Along Percentage, the Transferors shall send written notice of such Tag Along Offer (the “Profits Series Notice”), together with (i) the number of Requested Preferred Units and (ii) the Requested Preferred Tag-Along Percentage, to each of the Profits Series Tag Offerees. The Profits Series Tag Offerees shall have the following rights:

(i) Each Profits Series Tag Offeree shall have the right (a “Profits Series Inclusion Right”), exercisable by delivery of notice (a “Profits Series Tag-Along Exercise Notice”) to the Transferors at any time within 15 days after receipt of the Profits Series Inclusion Notice, to request to sell in the Tag-Along Sale, for each series of Profits Units held by such Profits Tag Offeree, a number of Profits Units of such series that are Eligible Units equal to the total number of Profits Units of such series (including Unvested and Vested Profits Units of such series) held by such Profits Series Tag Offeree multiplied by the Requested Preferred Tag-Along Percentage (for any series of Profits Units, the “Initial Requested Profits Series Units”). Promptly following the expiration of such 15-day period, the Transferors shall notify, for each series of Profits Units, the Profits Series Tag Offerees of the then Initial Requested Profits Series Tag-Along Percentage for such series of Profits Units and the names of each Profits Series Tag Offeree of such series of Profits Units who did not timely exercise his Profits Series Inclusion Right with respect to such series of Profits Units. If, with respect to any series of Profits Units, any Profits Series Tag Offeree does not timely exercise his Profits Series Inclusion Right with respect to such series of Profits Units by so delivering a Profits Series Tag-Along Exercise Notice prior to the expiration of such 15-day period, such that the Initial Requested Profits Tag-Along Percentage for such series of Profits Units is less than the Requested Preferred Tag-Along Percentage, the Profits Series Tag Offerees that exercised their Profits Series Inclusion Rights for such series shall have an additional five days in which to agree to sell in such Tag-Along Sale an aggregate number of additional Profits Units of such series that are Eligible Units that is equal to the number of Profits Units of such series that are Eligible Units that the non-exercising Profits Series Tag Offerees with respect to such series of Profits Units would have been entitled to request to sell had they exercised their Profits Series Inclusion Rights with respect to such series in accordance with the foregoing (the “Additional Requested Profits Series Units” and, together with the Initial Requested Profits Units of such series, the “Requested Profits

Series Units”). Each such Profits Series Tag Offeree who so agrees to sell additional Profits Units of such series that are Eligible Units shall be required to sell such additional number of Profits Units of such series that are Eligible Units as may be agreed upon by all exercising Profits Series Tag Offerees of such series, it being understood and agreed that the Profits Series Tag Offerees shall not be entitled to sell any Profits Units of such Series in such Tag-Along Sale unless the aggregate number of Profits Units of such Series that are Eligible Units so included in such sale is equal to (i) the aggregate number of Profits Units of such series (including Unvested and Vested Profits Units of such series) then outstanding multiplied by (ii) the Purchased Preferred Percentage. If, for any series of Profits Units, the exercising Profits Series Tag Offerees hold at least 40% of the total number of outstanding Profits Units of such series, but such Profits Series Tag Offerees do not hold a sufficient number of Profits Units of such series that are Eligible Units to permit them to comply with the foregoing sentence, such exercising Profits Series Tag Offerees shall be entitled to require each non-exercising Profits Series Tag Offeree to request to be included in such Tag-Along Sale, on a pro rata basis, up to a number of Profits Units of such series that are Eligible Units that shall cause the number of Profit Units of such that are Eligible Units that are requested to be included in such Tag-Along Sale to equal (i) the aggregate number of Profits Units of such series (including Unvested and Vested Profits Units of such series) then outstanding multiplied by (ii) the Requested Preferred Tag-Along Percentage. The exercising Profit Series Tag Offerees of such series of Profits Units shall send written notice to the Transferors on or prior to the end of such additional five-day period, which notice shall specify the number of Additional Requested Profits Series Units requested to be included in such Tag-Along Sale by each exercising Profits Series Tag Offeree (including each Profits Series Tag Offeree that was required to exercise Profits Series Inclusion Rights pursuant to this Section 7.6(d)(i)).

(e) Promptly following the completion of the procedures described in Section 7.6(c) and Section 7.6(d), the Transferors shall notify the Tag-Along Transferee of the number of Requested Preferred Units, and the number of Requested Profits Series Units for each applicable series of Profits Units. If the Tag-Along Transferee is unwilling to purchase all of the Preferred Units that the Transferors propose to sell in the Tag-Along Sale, all of the Requested Preferred Units and all of the Requested Profits Units, then the Transferors shall determine what percentage of Preferred Units and Profits Units (which percentage shall be the same for each class of Units, and each series within each class of Units) such Tag-Along Transferee is willing to purchase in the aggregate (the “Purchased Percentage”). In such event, the number of Preferred Units that the Transferors propose to sell in the Tag-Along Sale and the number of the Requested Preferred Units and the Requested Profits Units that the Transferors and each of the exercising Preferred Tag Offerees and Profits Series Tag Offerees otherwise would have sold shall be reduced on a pro rata basis (based on the respective total numbers of Preferred Units and Profits Units that are Eligible Units that such holders desired to sell) so as to permit the Transferors, the exercising Preferred Tag Offerees, and the exercising Profits Series Tag Offerees to sell in the aggregate (i) a number of Preferred Units equal to the total number of Preferred Units multiplied by the Purchased Percentage (the “Purchased Preferred Units”), and, for each series of Profits Units that are to be included in the sale, (ii) a number of Profits Units that are Eligible Units equal to the total number of Profits Units of such series then outstanding

multiplied by the Purchased Percentage. The total amount of Profits Units to be sold for each series of Profits Units to be included in the Tag-Along Sale is referred to as the “Purchased Profits Units”.

(f) Notwithstanding anything to the contrary in this Section 7.6, if the consideration proposed to be paid by the Tag-Along Transferee in a Tag-Along Sale includes securities with respect to which no registration statement covering the issuance of such securities has been declared effective under the Securities Act, then each holder of Units participating in the Tag- Along Sale that is not then an Accredited Investor (without regard to Rule 501(a)(4)) may be required, at the request and election of the Transferors, to (i) appoint a purchaser representative (as such term is defined in Rule 501 under the Securities Act) reasonably acceptable to such Transferors or (ii) agree to accept cash in lieu of any securities such holder would otherwise receive in an amount equal to the fair market value of such securities, as determined by the Board in its reasonable judgment.

(g) The Preferred Tag Offerees, the Profits Series Tag Offerees and the Transferors shall sell to the Tag-Along Transferee all of the Purchased Preferred Units, and Purchased Profit Units proposed to be transferred by them in accordance with this Section 7.6 at not less than the price and upon the terms and conditions, if any, not more favorable, individually and in the aggregate, to the Tag-Along Transferee than those in the Tag-Along Offer and the Preferred Inclusion Notice, at the time (subject to extension to the extent necessary to pursue any required regulatory approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) and place provided for the closing in the Tag-Along Offer, or at such other time and place as the Preferred Tag Offerees, the Profits Series Tag Offerees, the Transferors and the Tag-Along Transferee shall agree.

(h) The aggregate proceeds for the Purchased Preferred Units and the Purchased Profits Units sold pursuant to a Tag-Along Sale shall be distributed first in accordance with the provisions of Section 6.1(c)(i) and Section 6.1(e), if applicable, and then in accordance with the priorities and preferences set forth in Section 6.1(c).

(i) The Warburg Pincus Group shall have the right in connection with any Tag-Along Sale (or in connection with the investigation or consideration of any potential Tag-Along Sale) to require the Company to cooperate fully with potential acquirors in such prospective Tag-Along Sale by taking all customary and other actions reasonably requested by such Transferors or such potential acquirors, including making the Company’s properties, books and records, and other assets reasonably available for inspection by such potential acquirors, establishing a physical or electronic data room including materials customarily made available to potential acquirors in connection with such processes and making its employees reasonably available for presentations, interviews and other diligence activities, in each case subject to reasonable and customary confidentiality provisions. The Company shall provide assistance with respect to these actions as reasonably requested.

(j) For purposes of this Section 7.6, the following terms shall have the following meanings:

(i) “Initial Profits Series Tag-Along Percentage” means, with respect to any series of Profits Units, the percentage determined by dividing (x) the aggregate number of Initial Requested Profits Units for such series by (y) the total number of outstanding Units of such series of Profits Units (including Unvested and Vested Profits Units of such series).

(ii) “Preferred Tag Offeree” means each of the Eligible Sellers that owns Preferred Units.

(iii) “Profits Series Tag Offeree” means each of the Eligible Sellers that owns Profits Units.

(iv) “Purchased Preferred Percentage” means the percentage determined by dividing (x) the Purchased Preferred Units by (y) the total number of outstanding Preferred Units.

(v) “Requested Preferred Tag-Along Percentage” means, as of a specified date, the percentage determined by dividing (x) the Requested Preferred Units by (y) the total number of outstanding Preferred Units.

(vi) “Requested Preferred Units” means (x) the aggregate number of Preferred Units requested to be included in a Tag-Along Sale by all Preferred Tag Offerees exercising their Preferred Inclusion Rights plus (y) the number of Preferred Units that the Transferors propose to sell in a Tag-Along Sale.

(vii) “Requested Profits Series Tag-Along Percentage” means, as of a specified date and with respect to any series of Profits Units, the percentage determined by dividing (x) the Requested Profits Units of such series by (y) the total number of outstanding Profits Units of such series (including Unvested and Vested Profits Units of such series).

(viii) “Transferor Requested Preferred Percentage” means the percentage determined by dividing (x) the aggregate number of Preferred Units that the Transferors propose to sell in a Tag-Along Sale by (y) the total number of outstanding Preferred Units.

(k) Notwithstanding anything to the contrary in this Agreement, at any time after the six-month anniversary of the date of the Inclusion Notice with respect to each proposed Tag- Along Sale, the Company shall be entitled to waive, on behalf of each Eligible Seller, each former Eligible Seller and each of their respective Affiliates, successors and assigns and the members, partners, stockholders, directors, managers, officers, liquidators and employees of each of the foregoing (collectively, the “Eligible Seller Persons”) any and all claims such Eligible Seller Persons have, had or may have or had with respect to any non-compliance or violation of this Section 7.6 by any Person with respect to such Tag-Along Sale (whether or not any Units were Disposed of pursuant to this Section 7.6), other than any such claim that has been made in writing and delivered to the Company prior to the expiration of such six-month anniversary.

Section 7.7 Qualified Public Offering.

(a) In connection with any proposed Qualified Public Offering approved in accordance with this Agreement, the outstanding Units will be converted in accordance with this Section 7.7 into equity securities of the IPO Issuer (“IPO Securities”) of the same class or series as the securities of the IPO Issuer proposed to be offered to the public in the Qualified Public Offering (the “Publicly Offered Securities”). In connection therewith, each outstanding Unit will be converted into or exchanged for IPO Securities in a transaction or series of transactions that give effect to the provisions of Section 6.1(c), Section 6.1(d), Section 6.1(e) and Section 6.1(f) (the “IPO Exchange”) such that each holder of Units will receive IPO Securities having a value equal to the same proportion of the aggregate Pre-IPO Value that such holder would have received if all of the Company’s cash and other property had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in Section 6.1 as in effect immediately prior to such distribution assuming that (i) the value of the IPO Issuer immediately prior to such liquidation distribution was equal to the Pre-IPO Value, (ii) all Unvested Profits Units were Vested Profits Units and therefore entitled to all Withheld Amounts with respect to such Unvested Profits Units, and (iii) the holders of Profits Units were entitled to all Retained Amounts; provided, however, that the IPO Securities issued with respect to Unvested Profits Units shall remain subject to vesting in accordance with, and to the extent provided in, the applicable Restricted Unit Agreement, and provided, further, that if the foregoing provisions would result in the holders of Profits Units receiving either no or only a nominal amount of IPO Securities, then the Board, acting in good faith, shall grant to each of such holders of Profits Units options to purchase IPO Securities that are at the time of such grant reasonably equivalent in value in the aggregate to the Profits Units held by such holders and thereupon such Profits Units shall be automatically canceled and provided, further, that if the value of the IPO Securities to be distributed to the holders of Preferred Units in connection with the IPO Exchange is less than the amount that would be required to be distributed pursuant to Section 6.1(c) to result in the Preferred Unit Preference Amounts for all outstanding Preferred Units to be reduced to zero, then the IPO Securities to be distributed in exchange for the Retained Amounts shall instead be distributed to the holders of Preferred Units in an amount (to the extent possible) equal to the amount that would be required to be distributed to the holders of Preferred Units pursuant to Section 6.1(c) to result in the Preferred Unit Preference Amounts for all outstanding Preferred Units to be reduced to zero. The market value of any IPO Securities issued in connection with the IPO Exchange will be deemed to be the price at which the Publicly Offered Securities were initially sold by the underwriters, which underwriters will be led by a qualified independent investment bank with a national reputation. If, in connection with the IPO Exchange, the Board determines that it is advisable to have all of the Units contributed by the holders thereof in one or a series of transactions to the IPO Issuer pursuant to an agreement that provides for the exchange of Units into IPO Securities of such Person (with the amount of IPO Securities to be received by each such holder being determined in accordance with this Section 7.7), each holder of Units agrees to participate in such an exchange. Prior to effecting any IPO Exchange in accordance with this Section 7.7, the Company will offer to each non-Defaulting Member that holds Series A-2 Preferred Units the option to purchase additional Series A-2 Preferred Units up to the amount of such Member’s Remaining Commitment.

(b) Notwithstanding anything to the contrary in this Agreement, at any time after the approval of a Qualified Public Offering in accordance with this Agreement, the Board shall be entitled to approve the transaction or transactions to effect the IPO Exchange in accordance with this Section 7.7 without the consent or approval of any other Person (including any Member). If the Company elects to exercise its rights under this Section 7.7, each of the Members shall (i) take such actions as may be reasonably necessary or required in connection with consummating the IPO Exchange and (ii) use commercially reasonable efforts to (x) cooperate with the other Members so that the IPO Exchange is undertaken in a tax-efficient manner and (y) if any Institutional Investor or its limited partners or investors has a structure involving ownership of all or a portion of its interests in the Company, directly or indirectly, through one or more single purpose entities (a “Blocker Corporation”), at the request of any such Institutional Investor, merge its Blocker Corporation into the IPO Issuer in a tax-free reorganization, utilize such Blocker Corporation as the IPO Issuer or otherwise structure the transaction so that the Blocker Corporation is not subject to a level of corporate tax on the Qualified Public Offering or subsequent dividend payments or sales of stock, so long as, with respect to each of clauses (x) and (y), the foregoing could not reasonably be expected to result in any costs or liabilities that are not indemnified or reimbursed by the holders of Capital Stock or Affiliates of the Blocker Corporation or other adverse effects (other than de minimis adverse effects) to the Company or any of the Members (other than to (A) the Blocker Corporation in the event that the Blocker Corporation is neither merged nor otherwise combined with the Company or the IPO Issuer nor utilized as the IPO Issuer and (B) the Institutional Investor or its Affiliates through which the Blocker Corporation directly or indirectly holds its interest in the Company).

(c) Each Member shall sell any fractional IPO Securities owned by such party (after taking into account all IPO Securities held by such party) to the IPO Issuer, upon the request of the Company in connection with or in anticipation of the consummation of a Qualified Public Offering, for cash consideration equal to the fair value of such fractional securities, as determined by the Board.

(d) Notwithstanding anything to the contrary in this Section 7.7, if no registration statement covering the issuance of the IPO Securities to the Members in the IPO Exchange has been declared effective under the Securities Act, then each of the Members that is not then an Accredited Investor (without regard to Rule 501(a)(4)) may be required, at the request and election of the Company, to (i) appoint a purchaser representative (as such term is defined in Rule 501 under the Securities Act) reasonably acceptable to the Company or (ii) agree to accept cash in lieu of any IPO Securities such Member would otherwise receive in an amount equal to the fair value of such IPO Securities, as determined by the Board in its reasonable judgment.

(e) If so requested by any Institutional Investor that holds Preferred Units, the certificate of incorporation (if the IPO Issuer is a corporation) or other organizational documents (if the IPO Issuer is a Person other than a corporation) of the IPO Issuer shall include a provision substantially the same as Section 8.6(b) hereof.

Section 7.8 Preemptive Rights.

(a) Prior to the Company issuing (other than through issuances of (i) Series A-2 Preferred Units to Committed Members pursuant to Commitment Contributions made in accordance with Article 5, (ii) Profits Units, (iii) options to purchase Units pursuant to incentive equity plans approved by the Compensation Committee, (iv) Units issued to any Person that is not a Member or an Affiliate thereof as consideration in any acquisition or other strategic transaction (such as a joint venture, marketing or distribution arrangement, or technology transfer or development arrangement) approved in accordance with this Agreement, (v) Units issued in connection with any split, distribution or recapitalization of the Company, (vi) any Capital Stock issued by the IPO Issuer pursuant to a registration statement filed under the Securities Act and approved in accordance with this Agreement and (vii) IPO Securities in connection with an IPO Exchange pursuant to this Agreement (each such issuance, an “Excluded Unit Issuance”)) any Units or options or other rights to acquire Units, whether through exchange, conversion or otherwise (collectively, the “New Units”) to a proposed purchaser (the “Proposed Purchaser”), each Eligible Purchaser shall have the right to purchase the number of New Units as provided in this Section 7.8.

(b) The Company shall give each Eligible Purchaser at least 15 days’ prior notice (the “First Notice”) of any proposed issuance of New Units, which notice shall set forth in reasonable detail the proposed terms and conditions thereof and shall offer to each Eligible Purchaser the opportunity to purchase its Pro Rata Share (which Pro Rata Share shall be calculated as of the date of such notice) of the New Units at the same price, on the same terms and conditions and at the same time as the New Units are proposed to be issued by the Company. If any Eligible Purchaser wishes to exercise its preemptive rights, it must do so by delivering an irrevocable written notice to the Company within 15 days after delivery by the Company of the First Notice (the “Election Period”), which notice shall state the dollar amount of New Units such Eligible Purchaser (each a “Requesting Purchaser”) would like to purchase up to a maximum amount equal to such Eligible Purchaser’s Pro Rata Share of the total offering amount plus the additional dollar amount of New Units such Requesting Purchaser would like to purchase in excess of its Pro Rata Share (the “Over-Allotment Amount”), if any, if other Eligible Purchasers do not elect to purchase their full Pro Rata Share of the New Units. The rights of each Requesting Purchaser to purchase a dollar amount of New Units in excess of each such Requesting Purchaser’s Pro Rata Share of the New Units shall be based on the relative Pro Rata Share of the New Units of those Requesting Purchasers desiring Over-Allotment Amounts and not based on the Requesting Purchasers’ relative Over-Allotment Amounts.

(c) If not all of the New Units are subscribed for by the Eligible Purchasers, the Company shall have the right, but shall not be required, to issue and sell the unsubscribed portion of the New Units to the Proposed Purchaser at any time during the 90 days following the termination of the Election Period pursuant to the terms and conditions set forth in the First Notice. The Board may, in its reasonable discretion, impose such other reasonable and customary terms and procedures such as setting a closing date, rounding the number of Units covered by this Section 7.8 to the nearest whole Unit and requiring customary closing deliveries in connection with any preemptive rights offering. In the event any Eligible Purchaser refuses to purchase offered Units for which it subscribed pursuant to the exercise of preemptive rights

granted thereto under this Section 7.8, in addition to any other rights the Company may be permitted to enforce at law or in equity, such Eligible Purchaser and any Permitted Transferee of such Eligible Purchaser shall not be considered an Eligible Purchaser for any future rights granted under this Section 7.8 unless the Board expressly designates such Person as an Eligible Purchaser (which the Board, in its sole discretion, may do on an offer-by-offer basis or not at all) and shall be deemed to be a Defaulting Member subject to the provisions of Section 5.4.

(d) Notwithstanding anything to the contrary in this Agreement, at any time after the six-month anniversary of the First Notice with respect to each proposed issuance of New Units pursuant to this Section 7.8, the Company shall be entitled to waive, on behalf of each Eligible Purchaser, each former Eligible Purchaser and each of their respective Affiliates, successors and assigns and the members, partners, stockholders, directors, managers, officers, liquidators and employees of each of the foregoing (collectively, the “Eligible Purchaser Persons”) any and all claims such Eligible Purchaser Persons have, had or may have or had with respect to any non¬compliance or violation of this Section 7.8 by any Person with respect to such proposed issuance of New Units (whether or not any Units were issued or sold pursuant to this Section 7.8), other than any such claim that has been made in writing and delivered to the Company prior to the expiration of such six-month anniversary.

Section 7.9 Registration Rights. The Members will have the registration rights set forth in Exhibit D.

Section 7.10 Specific Performance. Each Member acknowledges that it shall be inadequate or impossible, or both, to measure in money the damage to the Company or the Members, if any of them or any transferee or any legal representative of any party hereto fails to comply with any of the restrictions or obligations imposed by this Article 7, that every such restriction and obligation is material, and that in the event of any such failure, the Company or the Members shall not have an adequate remedy at law or in damages. Therefore, each Member consents to the issuance of an injunction or the enforcement of other equitable remedies against such Member at the suit of an aggrieved party without the posting of any bond or other security, to compel specific performance of all of the terms of this Article 7 and to prevent any Disposition of Units in contravention of any terms of this Article 7, and waives any defenses thereto, including the defenses of: (i) failure of consideration, (ii) breach of any other provision of this Agreement, and (iii) availability of relief in damages.

Section 7.11 Termination Following Qualified Public Offering or Change of Control. Notwithstanding anything to the contrary in this Article 7, (a) the provisions of this Article 7 (other than Section 7.2) shall terminate and be of no further force or effect upon the consummation of a Qualified Public Offering and (b) the provisions of Section 7.5 shall terminate and be of no further force or effect upon the consummation of a Change of Control.

LIMITATION OF LIABILITY AND INDEMNIFICATION

Section 9.1 Limitation of Liability and Indemnification.

(a) Except as otherwise provided in any Transaction Document, no Manager (solely in such individual’s capacity as a Manager) nor any of its Affiliates shall be liable to the Company or to any Member for losses sustained or liabilities incurred as a result of any act or omission taken or omitted by such Manager in his capacity as such; provided, that such Manager’s conduct did not constitute fraud or knowing violation of Law.

(b) Subject to its obligations and duties as set forth in Section 8.1 and Section 8.2, the Board may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and neither the Board nor any individual Manager (acting solely in such individual’s capacity as a Manager) shall be responsible or liable to the Company or any Member for any mistake, action, inaction, misconduct, negligence, fraud or bad faith on the part of any such agent appointed by the Board unless, with respect to an individual Manager only, such Manager had knowledge that such agent was acting unlawfully or engaging in fraud.

(c) Any Covered Person acting for, on behalf of or in relation to, the Company in respect of any transaction, any investment or any business decision or action, or otherwise shall be entitled to rely on the provisions of the Transaction Documents and on the advice of counsel, accountants and other professionals that is provided to the Company or such Covered Person, and such Covered Person shall not be liable to the Company or to any Member for such Covered Person’s reliance on any Transaction Document or such advice, provided, that such Covered Person’s conduct did not constitute fraud or knowing violation of Law. Except as otherwise required pursuant to any Transaction Document, notwithstanding any provisions of Law or in equity to the contrary, whenever a Covered Person is permitted or required to make a decision in its “sole discretion” or “discretion” or under a grant of similar authority or latitude, such Covered Person shall be entitled to consider only such interests (including its own interests) and factors as it desires, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Company, the Members or any other Person to the fullest extent permitted by applicable Law. Each Member acknowledges and agrees that any Manager designated by an Institutional Investor, or its transferees or successors, pursuant to Section 8.2 shall serve in such capacity to represent the interests of the Members that designated such Manager and shall be entitled to consider only such interests (including the interests of the Members that designated such Manager) and factors specified by the Members that designated such Manager, and shall not owe duties, fiduciary or otherwise, at Law, in equity or under the Transaction Documents, to the Company, any other Member or to any creditor of the Company (even if the Company is insolvent or near insolvency). The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities of a Manager or Member otherwise existing at Law or in equity, are agreed by the Members to replace, to the fullest extent permitted by applicable Law, such other duties and liabilities of such Manager or Member. This Section 9.1 does not create any duty or liability of a Covered Person that does not otherwise exist at Law or in equity.

Notwithstanding anything to the contrary under this Agreement or pursuant to any duty (fiduciary or otherwise) or otherwise applicable provision of Law or equity, a Member or Manager may enter into voting agreements or arrangements with one or more other Members regarding, among other things, the voting by such Member or by Managers appointed by such Member. Without limiting the scope of any such voting agreement or arrangement permitted hereunder, a voting agreement or arrangement may provide that Members may act in concert and that Managers may act in concert.

(d) Each Covered Person (regardless of such person’s capacity and regardless of whether another Covered Person is entitled to indemnification) shall be indemnified and held harmless by the Company (but only to the extent of the Company’s assets), to the fullest extent permitted under applicable Law, from and against any and all loss, liability and expense (including taxes; penalties; judgments; fines; amounts paid or to be paid in settlement; costs of investigation and preparations; and fees, expenses and disbursements of attorneys, whether or not the dispute or proceeding involves the Company or any Manager or Member) reasonably incurred or suffered by any such Covered Person in connection with the activities of the Company or its Subsidiaries, provided, that such Covered Person’s conduct did not constitute fraud or knowing violation of Law. Notwithstanding anything to the contrary in this Section 9.1(d), no Officer shall be entitled to indemnification hereunder if such Officer did not act in good faith and in a manner such Officer reasonably believed to be in, or not opposed to, the best interests of the Company. The indemnification provided by this Section 9.1 shall be in addition to any other rights to which a Covered Person may be entitled under any agreement, as a matter of Law or otherwise, both as to actions in such Covered Person’s capacity as a Covered Person hereunder and as to actions in any other capacity, and shall continue as to a Covered Person who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of such Covered Person. A Covered Person shall not be denied indemnification in whole or in part under this Section 9.1 because such Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(e) The Company shall advance to any Covered Person the expenses and other indemnification payments to which such Covered Person may be otherwise entitled; provided, however, that any such advance shall only be made if the Covered Person delivers a written affirmation by such Covered Person of its good faith belief that it is entitled to indemnification hereunder and agrees to repay all amounts so advanced if it shall ultimately be determined that such Covered Person is not entitled to be indemnified hereunder.

(f) Each Covered Person may rely, and shall incur no liability in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, paper, document, signature or writing reasonably believed by it to be genuine, and may rely on a certificate signed by an officer, agent or representative of any Person in order to ascertain any fact with respect to such person or within such Person’s knowledge, in each case provided, that such Covered Person’s conduct did not constitute fraud or knowing violation of Law.

(g) NOTWITHSTANDING ANYTHING IN ANY TRANSACTION DOCUMENT TO THE CONTRARY, TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER THE COMPANY NOR ANY COVERED PERSON SHALL BE LIABLE TO THE COMPANY, TO ANY MEMBER OR TO ANY OTHER PERSON MAKING CLAIMS ON BEHALF OF THE FOREGOING FOR CONSEQUENTIAL, EXEMPLARY, PUNITIVE, INCIDENTAL, INDIRECT OR SPECIAL DAMAGES, INCLUDING DAMAGES FOR LOSS OF PROFITS, LOSS OF USE OR REVENUE OR LOSSES BY REASON OF COST OF CAPITAL, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT, THE BUSINESS OF THE COMPANY OR ANY OF ITS SUBSIDIARIES, THE GRANTING OR WITHHOLDING OF ANY APPROVAL REQUIRED HEREUNDER OR THE TRANSACTIONS CONTEMPLATED HEREBY, REGARDLESS OF WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, VIOLATION OF ANY APPLICABLE DECEPTIVE TRADE PRACTICES ACT OR SIMILAR LAW OR ANY OTHER LEGAL OR EQUITABLE DUTY OR PRINCIPLE, AND THE COMPANY AND EACH COVERED PERSON RELEASE EACH OF THE OTHER SUCH PERSONS FROM LIABILITY FOR ANY SUCH DAMAGES.

(h) The obligations of the Company to the Covered Persons provided in the Transaction Documents or arising under Law are solely the obligations of the Company, and no personal liability whatsoever shall attach to, or be incurred by, any Member or other Covered Person for such obligations, to the fullest extent permitted by Law. The obligations of the Institutional Investors which are Members provided in the Transaction Documents or arising under Law are solely the obligations of such Member, and no personal liability whatsoever shall attach to, or be incurred by, any other Covered Person for such obligations, to the fullest extent permitted by Law. Where the foregoing provides that no personal liability shall attach to or be incurred by a Covered Person, any claims against or recourse to such Covered Person for or in connection with such liability, whether arising in common law or equity or created by rule of law, statute, constitution, contract or otherwise, are expressly released and waived under the Transaction Documents, to the fullest extent permitted by Law, as a condition of, and as part of the consideration for, the execution of the Transaction Documents and any related agreement, and the incurring by the Company or such Member of the obligations provided in such agreements.

(i) Unless otherwise expressly provided in this Agreement, whenever a conflict of interest exists or arises between a Covered Person or any of its Affiliates, on the one hand, and the Company or another Member, on the other, any resolution or course of action by such Covered Person or its Affiliates in respect of such conflict of interest shall be permitted and deemed approved by all Members, and shall not constitute a breach of this Agreement, of any other Transaction Document or of any duty stated or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by the disinterested holders of a majority of each series of Units then outstanding (voting as a separate class), (ii) determined by such Covered Person in accordance with the provisions of Section 9.1(c) above to be on terms no less favorable to the Company than those generally being provided to or available from unrelated third parties or (iii) determined by such Covered Person in accordance with the provisions of Section 9.1(c) above to be fair and reasonable to the Company, taking into account the totality of the relationships among the parties involved (including other transactions that may

be particularly favorable or advantageous to the Company). If the resolution or course of action taken with respect to a conflict of interest is determined by the Board to satisfy either of the standards set forth in clauses (ii) or (iii) above, then it shall be presumed that, in making such decision, the Board acted in accordance with the standards set forth in the Transaction Documents, and in any proceeding brought by any Member or by or on behalf of such Member or any other Member or the Company challenging such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption.

(j) Nothing in this Section 9.1 shall be deemed to limit or waive any rights that any Person has for breach of contract under the terms of the Transaction Documents; provided, however, that each Member acknowledges that it is not relying upon any other Member or any of such other Member’s Affiliates, or any of such other Member’s or such other Member’s Affiliates’ respective stockholders, partners, members, directors, officers or employees, in making its investment or decision to invest in the Company or in monitoring such investment, and each Member hereby agrees that any claims against, actions, rights to sue, other remedies or other recourse to or against any other Member and such other Member’s Affiliates and any of such other Member’s or such other Member’s Affiliates’ respective stockholders, partners, members, directors, officers, managers, liquidators and employees (collectively, the “Released Persons”) for or in connection with any breach by any Released Person of the terms of any Transaction Document (other than a breach by a Released Person of its obligations under Section 7.4, Section 7.5 or Section 7.6) are expressly released and waived by each Member, in each case to the fullest extent permitted by Law. For the avoidance of doubt, the Company shall not be deemed to have waived or released its rights against any Released Person for a breach of such Released Person’s obligations to the Company pursuant to the Transaction Documents. For purposes of this Section 9.1(j), the Company and its Subsidiaries shall be deemed to not be an Affiliate of any Released Person.

(k) Any amendment, modification or repeal of this Section 9.1 or any provision hereof shall be prospective only and shall not in any way affect the limitations on liability of the Covered Persons, or terminate, reduce or impair the right of any past, present or future Covered Person, under and in accordance with the provisions of this Section 9.1 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 9.2 Insurance. The Company shall maintain insurance (including directors’ and officers’ insurance), at its expense, to protect each Manager and Officer of the Company, and the Company may maintain such insurance to protect itself and any Covered Person or other Member of the Company, in each case against any expense, liability or loss, whether or not the Company would have the power to indemnify such Person against such expense, liability or loss under the Act.

The records shall include complete and accurate information regarding the state of the business and financial condition of the Company; a copy of the Certificate and this Agreement and all amendments thereto; a current list of the names and last known business, residence or mailing addresses of all Members; and the Company’s federal, state and local tax returns for the Company’s six most recent tax years.

Section 10.4 Accounts. The Company shall establish one or more separate bank and investment accounts and arrangements for the Company, which shall be maintained in the Company’s name with financial institutions and firms that the Board may determine.

Section 10.5 Information.

(a) No Member shall be entitled to obtain any information relating to the Company except as expressly provided in this Agreement or to the extent required by the Act; and to the extent a Member is so entitled to such information, such Member shall be subject to the provisions of Section 10.5(b).

(b) Each Member agrees that all Confidential Information shall be kept confidential by such Member and shall not be disclosed by such Member in any manner whatsoever; provided, however, that (i) any of such Confidential Information may be disclosed to such Member’s Affiliates, to Persons who are (or who are prospective) beneficial owners of equity interests in such Member and to managers; directors; officers; employees; and authorized representatives (including attorneys, accountants, consultants, bankers and financial advisors) of

such Member and of such Member’s Affiliates (collectively, for purposes of this Section 10.5(b), “Representatives”), each of which Representatives shall be bound by the provisions of this Section 10.5(b) or substantially similar terms; (ii) any disclosure of Confidential Information may be made to the extent to which the Company consents in writing; (iii) any disclosure may be made of the terms of a Member’s investment in the Company pursuant to this Agreement and the performance of that investment to the extent in compliance with applicable Law (whether in the Member’s fundraising materials or otherwise); (iv) Confidential Information may be disclosed by a Member or Representative to the extent reasonably necessary in connection with such Member’s enforcement of its rights under this Agreement; and (v) Confidential Information may be disclosed by any Member or Representative to the extent that the Member or Representative has received advice from its counsel that it is legally compelled to do so, provided, that, prior to making such disclosure, the Member or Representative, as the case may be, uses reasonable efforts to preserve the confidentiality of the Confidential Information, including consulting with the Company regarding such disclosure and, if reasonably requested by the Company, assisting the Company, at the Company’s expense, in seeking a protective order to prevent the requested disclosure, and provided, further, that the Member or Representative, as the case may be, discloses only that portion of the Confidential Information as is, based on the advice of its counsel, legally required.

(c) Notwithstanding anything to the contrary in this Agreement, no holder of Profits Units shall be entitled to obtain from the Company or any other Member any information with respect to another holder of Profits Units or the terms of such holder’s Profits Units, including the number of Profits Units held by any other holder of Units.

(d) The obligations of a Member pursuant to this Section 10.5 will continue following the time such Person ceases to be a Member, but thereafter such Person will not have the right to enforce the provisions of this Agreement.

ARTICLE 11

TAXES

Section 11.1 Tax Returns. The Company shall prepare and timely file all U.S. federal, state and local and foreign tax returns required to be filed by the Company. Unless otherwise agreed by the Board, any income tax return of the Company shall be prepared by an independent public accounting firm of recognized national standing selected by the Board. Each Member shall furnish to the Company all pertinent information in its possession relating to the Company’s operations that is necessary to enable the Company’s tax returns to be timely prepared and filed. The Company shall deliver to each Member within 75 calendar days after the end of the applicable fiscal year (or such longer period of time not in excess of 120 days after the end of the applicable fiscal year as is approved by the Board), a Schedule K-l together with such additional information as may be required by the Members in order to file their individual returns reflecting the Company’s operations. The Company shall bear the costs of the preparation and filing of its tax returns.

Section 11.2 Tax Partnership. It is the intention of the Members that the Company be classified as a partnership for U.S. federal income tax purposes. Unless otherwise approved in accordance with Section 8.5(a), neither the Company nor any Member shall make an election for the Partnership to be excluded from the application of the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state law or to be classified as other than a partnership pursuant to Treasury Regulation Section 301.7701-3.

Section 11.3 Tax Elections. The Company shall make the following elections on the appropriate forms or tax returns:

(a) to adopt the calendar year as the Company’s fiscal year, if permitted under the Code;

(b) to adopt the accrual method of accounting and to keep the Company’s books and records on the U.S. federal income tax method;

(d) any other election the Board may deem appropriate and in the best interests of the Members.

Section 11.4 Tax Matters Member.

(a) The tax matters partner of the Company pursuant to Code Section 6231 (a)(7) shall be a Member designated from time to time by the Board subject to replacement by the Board. (Any Member who is designated as the tax matters partner is referred to herein as the “Tax Matters Member”). The initial Tax Matters Member will be Raymond A. Foutch until such time as the Chief Financial Officer becomes a Member, at which time the Chief Financial Officer will be designated as the Tax Matters Member unless otherwise determined by the Board. The

Tax Matters Member shall take such action as may be necessary to cause to the extent possible each other Member to become a notice partner within the meaning of Code Section 6231(a)(8). The Tax Matters Member shall inform each other Member of all significant matters that may come to its attention in its capacity as Tax Matters Member by giving notice thereof on or before the fifth day after becoming aware thereof and, within that time, shall forward to each other Member copies of all significant written communications it may receive in that capacity.

(b) The Tax Matters Member shall take no action without the authorization of the Board, other than such action as may be required by Law. Any cost or expense incurred by the Tax Matters Member in connection with its duties, including the preparation for or pursuance of administrative or judicial proceedings, shall be paid by the Company.

(c) The Tax Matters Member shall not enter into any extension of the period of limitations for making assessments on behalf of the Members without first obtaining the consent of the Board. The Tax Matters Member shall not bind any Member to a settlement agreement without obtaining the consent of such Member. Any Member that enters into a settlement agreement with respect to any Company item (within the meaning of Code Section 6231(a)(3)) shall notify the other Members of such settlement agreement and its terms within 90 days from the date of the settlement.

(d) No Member shall file a request pursuant to Code Section 6227 for an administrative adjustment of Company items for any taxable year without first notifying the other Members. If the Board consents to the requested adjustment, the Tax Matters Member shall file the request for the administrative adjustment on behalf of the Members. If such consent is not obtained within 30 days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member, including the Tax Matters Member, may file a request for administrative adjustment on its own behalf. Any Member intending to file a petition under Code Sections 6226 or 6228 or other Code Section with respect to any item involving the Company shall notify the other Members of such intention and the nature of the contemplated proceeding. In the case where the Tax Matters Member is the Member intending to file such petition on behalf of the Company, such notice shall be given within a reasonable period of time to allow the other Members to participate in the choosing of the forum in which such petition will be filed.

(e) If any Member intends to file a notice of inconsistent treatment under Code Section 6222(b), such Member shall give reasonable notice under the circumstances to the other Members of such intent and the manner in which the Member’s intended treatment of an item is (or may be) inconsistent with the treatment of that item by the other Members.

Section 11.5 Section 83(b) Election. Each Member who acquires Profits Units acknowledges and agrees to make an election under Code Section 83(b) and to consult with such Member’s tax advisor to determine the tax consequences of such acquisition and of filing an election under Code Section 83(b). Each such Member acknowledges that it is the sole responsibility of such Member, and not the Company, to file the election under Code Section 83(b) even if such Member requests the Company or its Representatives to assist in making such filing.

Section 11.6 Section 83 Safe Harbor Election. By executing this Agreement, each Member authorizes and directs the Company to elect to have the “Safe Harbor” described in the proposed Revenue Procedure set forth in Internal Revenue Service Notice 2005-43 (the “IRS Notice”), including any similar safe harbor in any finalized Revenue Procedure, Revenue Ruling or Treasury Regulation, apply to any interest in the Company transferred to a service provider by the Company on or after the effective date of such final pronouncement in connection with services provided to the Company. For purposes of making such Safe Harbor election, the Tax Matters Member is hereby designated as the “partner who has responsibility for Federal income tax reporting” by the Company and, accordingly, execution of such Safe Harbor election by the Tax Matters Member constitutes execution of a “Safe Harbor Election” in accordance with the IRS Notice or any similar provision of any final pronouncement. The Company and each Member hereby agree to comply with all requirements of any such Safe Harbor, including any requirement that a Member prepare and file all Federal income tax returns reporting the income tax effects of each Interest issued by the Company in connection with services in a manner consistent with the requirements of the IRS Notice or other final pronouncement. A Member’s obligations to comply with the requirements of this Section shall survive such Member’s ceasing to be a member of the Company and the termination, dissolution, liquidation and winding up of the Company.

ARTICLE 12

DISSOLUTION, WINDING-UP AND TERMINATION

Section 12.1 Dissolution. Subject to Section 12.1(b), the Company shall be liquidated and its affairs shall be wound up on the first to occur of the following events (each a “Liquidation Event) and no other event shall cause the Company’s dissolution:

(i) the consent of the Board and the approvals required under Section 8.5(a) and Section 8.5(b), as applicable;

(ii) at any time when there are no Members; and

(iii) entry of a decree of judicial dissolution of the Company under Section 18- 802 of the Act.

(b) If the Liquidation Event described in Section 12.1(a)(ii) shall occur, the Company shall not be dissolved, and the business of the Company shall be continued, if the requirements of Section 18-801 of the Act for the avoidance of dissolution are satisfied (a “Continuation Election”).

(c) Except as otherwise provided in this Section 12.1, to the maximum extent permitted by the Act, the death, retirement, Resignation, expulsion, Bankruptcy or dissolution of a Member or the commencement or consummation of separation proceedings shall not constitute a Liquidation Event and, notwithstanding the occurrence of any such event or circumstance, the business of the Company shall be continued without dissolution.

Section 12.2 Winding-Up and Termination. On the occurrence of a Liquidation Event, unless a Continuation Election is made, the Board may select one or more Persons to act as liquidator or may itself act as liquidator. The liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and in the Act. The costs of winding up shall be borne as a Company expense, including reasonable compensation to the liquidator if approved by the Board. Until final distribution, the liquidator shall continue to operate the Company properties with all of the power and authority of the Board. The steps to be accomplished by the liquidator are as follows:

(a) as promptly as possible after dissolution and again after final winding up, the liquidator shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Company’s assets, liabilities and operations;

(b) the liquidator shall pay, satisfy or discharge from Company funds all of the debts, liabilities and obligations of the Company (including all expenses incurred in winding up) or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine); and

(i) the liquidator may sell any or all Company property, including to Members, and any resulting gain or loss from each sale shall be computed and allocated to the Capital Accounts of the Members in accordance with the provisions of Article 6;

(ii) with respect to all Company property that has not been sold, the fair market value of that property shall be determined and the Capital Accounts of the Members shall be adjusted to reflect the manner in which the unrealized income, gain, loss and deduction inherent in property that has not been reflected in the Capital Accounts previously would be allocated among the Members if there were a taxable disposition of that property for the fair market value of that property on the date of distribution; and

(iii) Company property shall be distributed among the Members in accordance with Section 6.1(c), and those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 days after the date of the liquidation).

All distributions in kind to the Members shall be made subject to the liability of each distributee for costs, expenses and liabilities theretofore incurred or for which the Company has committed prior to the date of termination and those costs, expenses and liabilities shall be allocated to the distributee pursuant to this Section 12.1(c). The distribution of cash or property to the Members in accordance with the provisions of this Section 12.1(c) constitutes a complete return to such Member of its Capital Contributions and a complete distribution to the Members of its Membership Interests (including Units) and all the Company’s property and constitutes a

compromise to which all Members have consented within the meaning of Section 18-502(b) of the Act. To the extent that a Member returns funds to the Company, it has no claim against any other Member for those funds.

Section 12.3 Clawback. In connection with the winding-up and termination of the Company, each holder of Profits Units (as of the time of such winding-up and termination) shall be required to contribute to the Company the amount, if any, of such holder’s Profits Unit Clawback Amount. Notwithstanding the foregoing, no holder of Profits Units shall be required to make contributions pursuant to this Section 12.3 in an amount greater than the excess of the total distributions received by such holder with respect to Profits Units over the distributions made to such holder pursuant to Section 6.1(c) with respect to such holder’s Profits Units. Any amounts contributed to the Company pursuant to this Section 12.3 shall be available for distribution pursuant to Section 12.2(c).

Section 12.4 Deficit Capital Accounts. No Member shall be required to pay to the Company, to any other Member or to any third party any deficit balance which may exist from time to time in the Member’s Capital Account.

Section 12.5 Certificate of Cancellation. On completion of the distribution of Company assets as provided herein, the Board (or such other Person or Persons as the Act may require or permit) shall file a Certificate of Cancellation with the Secretary of State of Delaware, cancel any other filings made pursuant to Section 2.5, and take such other actions as may be necessary to terminate the existence of the Company. Upon the effectiveness of the Certificate of Cancellation, the existence of the Company shall cease, except as may be otherwise provided by the Act or other applicable Law.

ARTICLE 13

GENERAL PROVISIONS

Section 13.1 Offset. Whenever the Company is to pay or distribute any sum to any Member, any amounts that such Member, in its capacity as a Member, owes the Company, whether pursuant to this Agreement or another Transaction Document, may be deducted from that sum before payment or distribution.

Section 13.2 Notices.

(a) Except as expressly set forth to the contrary in this Agreement, all notices, requests or consents provided for or required to be given hereunder shall be in writing and shall be deemed to be duly given if personally delivered, telecopied and confirmed, or mailed by certified mail, return receipt requested, or nationally recognized overnight delivery service with

proof of receipt maintained, at the following addresses (or any other address that any such party may designate by written notice to the other parties):

(i) if to the Company, at the address of its principal executive offices;

(ii) if to a current Member, to the address given for the Member on Schedule I hereto; and

(iii) if to an additional Member or a holder of Membership Interests or Units that has not been admitted as a Member, to the address given for such Member or holder in an Addendum Agreement.

Any such notice shall, if delivered personally, be deemed received upon delivery; shall, if delivered by telecopy, be deemed received on the first business day following confirmation; shall, if delivered by certified mail, be deemed received upon the earlier of actual receipt thereof or five business days after the date of deposit in the United States mail, as the case may be; and shall, if delivered by nationally recognized overnight delivery service, be deemed received the first business day after the date of deposit with the delivery service.

(b) Whenever any notice is required to be given by Law, the Certificate or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

Section 13.3 Entire Agreement; Supersedure. This Agreement (including the Exhibits and Schedules) constitutes the entire agreement of the Members relating to the Company and supersedes all prior contracts or agreements with respect to the Company, whether oral or written.

Section 13.4 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Company. Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute-of-limitations period has run.

Section 13.5 Amendment or Restatement; Power of Attorney.

(a) Subject to Section 8.5, neither this Agreement (including any Exhibit or Schedule hereto) nor the Certificate may be amended, modified, supplemented or restated, nor may any provisions of this Agreement or the Certificate be waived, without Requisite Approval; provided, however, that (i) any such amendment, modification, supplement, restatement or waiver that by its explicit terms would alter or change the rights, obligations, powers or preferences specific to any series of Units in a disproportionate and adverse manner compared to the rights, obligations, powers and preferences specific to other series of Units shall require the prior written consent of Members holding a majority of the series of Units so disproportionately and adversely affected (other than any such holders that are Defaulting Members and the Units of such series held by such holders), (ii) except as otherwise provided in Section 5.4, any such amendment, modification, supplement, restatement or waiver that by its explicit terms would alter or change the rights, obligations, powers or preferences of any Member in its capacity as a holder of a

specific series of Units in a disproportionate and adverse manner compared to other Members in their capacities as holders of the same series of Units shall require the prior written consent of such Member so disproportionately and adversely affected, (iii) except as otherwise provided in Section 5.2(a) (with respect to Management Committed Members) or Section 12.3, any such amendment, modification, supplement, restatement or waiver that would by its explicit terms increase the Additional Commitment of any Member or require a Capital Contribution to the Company by any Member that has not made an Additional Commitment to the Company shall require the prior written consent of such Member, and (iv) any VCOC Amendment may be made without the consent of any party other than the Company and the Institutional Investor requesting the VCOC Amendment; provided, however, that any VCOC Amendment that adversely affects a Member in its capacity as a Member in a disproportionate manner compared to the other Members (other than the Institutional Investor requesting such amendment) in their capacities as Members shall require the consent of the adversely affected Member. The execution of an Addendum Agreement in connection with an issuance or transfer of Units made in accordance with the terms of this Agreement and changes to Schedule I hereof to reflect such transfers or issuances shall not be considered amendments to this Agreement and shall not require approval hereunder.

(b) Notwithstanding anything to the contrary in this Section 13.5, if (i) the provisions of Proposed Treasury Regulation Section 1.83-3 and related sections and the proposed Revenue Procedure described in IRS Notice 2005-43, as proposed by the Internal Revenue Service on May 24, 2005, or provisions similar thereto, or (ii) the amendments to Treasury Regulations §§ 1.704-1 and 1.704-3 proposed on January 22, 2003 (and corrected on March 28, 2003) are adopted as final (or temporary) rules (the “New Rules”), the Managers are authorized to make such amendments to this Agreement (including provision for any safe harbor election authorized by the New Rules) as the Managers may determine to be necessary or advisable to comply with or reflect the New Rules; provided, that such amendments do not materially alter the economic rights of the Members under this Agreement other than the timing of distributions pursuant to Section 6.1(b). Except as required by Law, no amendment, modification, supplement, discharge or waiver of or under this Agreement shall require the consent of any person not a party to this Agreement.

(c) Each Member irrevocably makes, constitutes and appoints each Manager of the Company, acting individually or collectively, as its true and lawful agent and attorney-in-fact, with full power of substitution and full power and authority in its name, place and stead, to make, execute, sign, acknowledge, swear to, record and file (i) any amendment, modification, supplement, restatement or waiver of any provision of this Agreement that has been approved in accordance with this Agreement and (ii) all other instruments, certificates, filings or papers not inconsistent with the terms of this Agreement which may be necessary or advisable in the determination of the Board to evidence an amendment, modification, supplement, restatement or waiver of, or relating to, this Agreement or to effect or carry out another provision of this Agreement or which may be required by law to be filed on behalf of the Company, including as may be necessary under Section 2.5. With respect to each Member, the foregoing power of attorney (x) is coupled with an interest, shall be irrevocable and shall survive the incapacity or Bankruptcy of such Member and (y) shall survive the Disposition by such Member of all or any portion of the Units held by such Member.

Section 13.6 Binding Effect. Subject to the restrictions on Dispositions set forth in this Agreement, this Agreement shall be binding upon and shall inure to the benefit of the Company and each Member and their respective heirs, permitted successors, permitted assigns, permitted distributees and legal representatives; and by their signatures hereto, the Company and each Member intends to and does hereby become bound. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any Person other than the parties hereto and their respective permitted successors and assigns any legal or equitable right, remedy or claim under, in or in respect of this Agreement or any provision herein contained. The rights under this Agreement may be assigned by a Member to a transferee of all or a portion of such Member’s Units transferred in accordance with this Agreement (and shall be assigned to the extent this Agreement requires such assignment), but only to the extent of such Units so transferred; it being understood that the assignment of any rights under this Agreement shall not constitute admission to the Company as a Member unless and until such transferee is duly admitted as a Member in accordance with this Agreement.

Section 13.7 Governing Law; Severability; Limitation of Liability.

(a) THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, WITHOUT REGARD TO THE CONFLICTS OF LAW PRINCIPLES OF SUCH STATE.

(b) The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware and the federal courts of the United States of America located in Delaware, and appropriate appellate courts therefrom, over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby (except as otherwise expressly provided in any employment agreement, non-competition and confidentiality agreement, confidentiality, non-solicitation and non-disparagement agreement, or Restricted Unit Agreement), and each party hereby irrevocably agrees that all claims in respect of such dispute or proceeding may be heard and determined in such courts. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for purposes of this Agreement and is not intended to, and shall not, confer consent to jurisdiction with respect to any other dispute in which a party to this Agreement may become involved. Each of the parties hereto hereby consents to process being served by any party to this Agreement in any suit, action or proceeding of the nature specified in this subsection (b) by the mailing of a copy thereof in the manner specified by the provisions of Section 13.2. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.

(c) In the event of a direct conflict between the provisions of this Agreement and (i) any provision of the Certificate or (ii) any mandatory, non-waivable provision of the Act, such

provision of the Certificate or the Act shall control. If any provision of the Act provides that it may be varied or superseded in the agreement of a limited liability company (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter.

(d) If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future Laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of each such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.

Section 13.8 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, the Company and each Member shall execute and deliver all such future instruments and take such other and further action as may be reasonably necessary or appropriate to carry out the provisions of this Agreement and the intention of the parties as expressed herein.

Section 13.9 Counterparts. This Agreement may be executed in any number of counterparts (including facsimile counterparts), all of which together shall constitute a single instrument.

Section 13.10 Fees and Expenses. The Company shall pay the reasonable documented legal fees and expenses of counsel to, and the reasonable documented out-of-pocket expenses incurred by, the Institutional Investors and the Management Team in connection with this Agreement and the transactions contemplated herein.

Section 13.11 Termination of Employment Arrangements. Each holder of Profits Units acknowledges and agrees that this Agreement, and the legal relationships created hereby, will not prevent the termination of any employment agreement or similar arrangement between such holder of Profits Units, on the one hand, and the Company or any of its Affiliates, on the other hand. Each holder of Profits Units agrees that the termination by the Company or any of its Affiliates of any employment, consulting or independent contractor relationship with such holder of Profits Units for any reason at any time will not be construed for any purpose to violate any duty or obligation of any other Member or Manager under this Agreement.

Section 13.12 Former Nomenclature for Series A Units. As of the date of this Agreement and for all purposes under this Agreement, all Units issued prior to the date hereof and referred to as “Series A Units” shall be hereinafter referred to as “Series A-l Preferred Units” and shall be subject to the terms applicable to such Units in this Agreement and the other Transaction Documents, as applicable.
