In the event that the Member(s) entitled to appoint a Director lose their right to designate a Director, one of such Member(s)’s appointees to the Board shall resign immediately, and the Members shall take all action necessary to remove such appointee and, subject to Section 3.2(c), the size of the Board shall be reduced accordingly.

(c) Adjustments to Size of Board. The size of the Board shall (1) decrease as, when and to the extent that (x) the Rollover Members lose their right to appoint a Director pursuant to the provisions of Section 3.2(b)(ii), or (y) the Summit Member(s) loses its right to appoint a Director pursuant to the provisions of Section 3.2(b)(i) or the Summit Member(s) otherwise chooses to appoint less than its full number of appointees as provided herein (provided that in no event shall the Board consist of less than one Director who shall, to the extent that neither the Rollover Members nor Summit Member(s) are entitled to appoint Directors pursuant to Section 3.2(b), be appointed by vote of a majority of the Members or on such other basis as agreed among all Members); and (2) increase as, when and to the extent that the Summit Member(s) has designated less than its full number of appointees and desires to designate an additional appointee or appointees to the Board (but not beyond the maximum number of Directors that the Summit Member(s) are otherwise entitled to appoint pursuant to Section 3.2(b)). In the event of any such change in the size of the Board as provided pursuant to this

Section 3.2, the Board change shall be automatic and not require further action by the Company, the Board or any Member. For the avoidance of doubt, the Summit Member(s) shall not be required to appoint all of its Directors and may designate less than the maximum number of Directors which it is entitled to appoint pursuant to Section 3.2(b) from time to time as it shall determine in its sole discretion.

(d) Chairman. To the extent the Directors so desire, they may, acting by vote of a majority in voting power of the Directors, appoint one Director as Chairman of the Board (the “Chairman”) to preside over meetings of the Board as provided herein. If the Chairman is absent at any meeting of the Board, the Directors present may designate, acting by vote of a majority in voting power of the Directors, another Director to serve as interim Chairman for that meeting. The Chairman shall have no authority or power to act for or on behalf of the Company, to do any act that would be binding on the Company or to make any expenditure or incur any obligations on behalf of the Company or authorize any of the foregoing, unless authorized by act of the Board.

(e) Reimbursement. All Directors will be entitled to reimbursement for documented, reasonable out-of-pocket expenses incurred in attending meetings of the Board or any committee thereof and shall be indemnified by the Company pursuant to Article IX but shall not otherwise be entitled to any compensation or fees in respect of his or her services as a Director of the Company.

SECTION 3.3. Board Meetings.

(a) Quorum; Required Vote for Board Action.

(i) Directors holding a majority of the total voting power of the Directors shall constitute a quorum for the transaction of business of the Board; provided that at least one Rollover Director is, or, solely to the extent that Special Board Approval is required in connection with any matter at the applicable Board meeting, such number of Rollover Directors required to pass an action by Special Board Approval are, in attendance. Notwithstanding the foregoing quorum requirement, in the event that a meeting of the Board is duly called and no such Rollover Director is in attendance, then no Rollover Director shall be required to constitute a quorum at the next meeting of the Board duly called (provided that no action requiring Special Board Approval shall be passed at any such meeting where the requisite number of Rollover Directors are not in attendance unless the Rollover Members holding a majority of the Class B Units held by the Rollover Members in the aggregate waive in writing their right to have the Rollover Directors present for the transaction of business to be held at such meeting).

(ii) Each Director shall have voting power determined as follows:

(A) each of the Directors other than the Summit Directors shall have one vote; and

(B) the Summit Directors collectively will have a number of votes equal to the number of Directors that the Summit Member(s) are entitled to appoint pursuant to Section 3.2(b)(i) at such time, and to the extent that less than the maximum number of Summit Directors are in attendance (in person, telephonically, by video conference or by proxy) at a meeting of the Board or any committee of the Board (including if the Summit Member(s) have appointed less than the maximum number of Summit Directors that the Summit Member(s) are entitled to appoint at such time), each Summit Director that is in attendance at the meeting of the Board (or committee of the Board, as applicable) will have a number of votes equal to the number of Directors that the Summit Member(s) are entitled to appoint pursuant to Section 3.2(b)(i) divided by the number of Summit Directors in attendance. In connection with any action by written consent the votes of Summit Directors so executing such written consent shall be allocated in a manner consistent with the foregoing.

Except as otherwise expressly provided in this Agreement, including Sections 3.3(a)(iii) and 3.3(a)(iv) below, the act of Directors holding a majority of the voting power present at a meeting of the Board at which a quorum is present shall be the act of the Board. A Director who is present at a meeting of the Board at which action on any matter is taken shall be presumed to have assented to the action unless such Director’s dissent shall be entered in the minutes of the meeting or unless he shall file such Director’s written dissent to such action with the Person acting as secretary of the meeting before the adjournment thereof or shall deliver such dissent to the Company immediately after the adjournment of the meeting. Such right to dissent shall not apply to a Director who voted in favor of such action.

(iii) Special Board Approval. So long as the Rollover Members are entitled to appoint a Director pursuant to Section 3.2(b)(ii), unless the Rollover Members holding a majority of the Class B Units held by the Rollover Members in the aggregate waive in writing their right to have the Rollover Directors present for the transaction of business held at such meeting, the following matters shall require the approval of (x) two Rollover Directors, to the extent that the Rollover Members are entitled to appoint at least two Directors pursuant to Section 3.2(b)(ii) and (y) one Rollover Director, to the extent that the Rollover Members are entitled to appoint only one Director pursuant to Section 3.2(b)(ii) (“Special Board Approval”) in addition to approval by a majority of the voting power of the Directors present at a meeting of the Board at which a quorum is present as provided in Section 3.3(a)(ii) or to the approvals required pursuant to Section 3.5 below, as applicable:

(A) any merger or consolidation of the Company or any of its Subsidiaries with or into any other Person (other than the merger of a Subsidiary with or into the Company or another Subsidiary), except in connection with a transaction subject to Section 5.4;

(B) any Transfer of Units that would result in a Change of Control of the Company prior to the fifth anniversary of the date of this Agreement other than any Transfer by the equityholders of Summit Holdco of their equity interests in Summit Holdco;

(C) any acquisition or divestiture by the Company or any of its Subsidiaries, whether by equity purchase or sale, equity exchange, purchase or sale of assets, merger, consolidation or otherwise, whether involving a single transaction or a series of related transactions, of or to another Person or business involving a purchase or sale price equal to or greater than $15 million, other than (w) purchases and sales of inventory, supplies, services or products by the Company and its Subsidiaries in the Ordinary Course of Business, (x) any payments required to be made pursuant to Section 9.3 of the Amended and Restated Operating Agreement of Green America Recycling, LLC, dated as of February 19, 2008 (as the same may be amended, restated or otherwise modified in accordance with its terms) or Section 5.6 of this Agreement or (y) in connection with a transaction subject to Section 5.4;

(D) (i) except as permitted without Special Board Approval under Section 2.9(b), the creation or issuance by the Company or any Subsidiary of (1) any Units, (2) any new class of Units, or (3) any other equity securities of the Company or any Subsidiary, in each case, other than any issuance of securities by a Subsidiary of the Company to another wholly-owned Subsidiary of the Company or the Company itself or in connection with any Unit or share split or Unit or share dividend paid on a proportionate basis to all equityholders of the Company or Subsidiary, as the case may be or (ii) except as permitted without Special Board Approval under Section 2.9(c), including in connection with the exercise of the Put Right or Call Right under Section 5.6, the repurchase of any Units or other equity securities of the Company or a Subsidiary of the Company, by the Company or any such Subsidiary;

(E) any liquidation, dissolution or winding up of the Company other than (x) as a result of the entry of an order, judgment or decree by any court of competent jurisdiction in a proceeding under Title 11 of the United States Code, as now constituted or as hereafter amended, or (y) in connection with a transaction subject to Section 5.4 in which the assets of the Company are distributed to the Members in a manner consistent with Section 4.4(a)(ii);

(F) any amendment to this Agreement (except as contemplated by Sections 2.9(a), 2.9(b), 2.9(d), 4.4(a), 5.1, 5.2(d) or 5.5 or any transaction contemplated by Sections 5.4, 5.5 or 5.6);

(G) any action to modify the governing organizational documents of a Subsidiary as contemplated by Section 3.6;

(H) the determination of gross fair market value of the Company’s assets in connection with any adjustment of the Gross Asset Value of the Company’s assets to their respective gross fair market value, as contemplated by paragraph (b) of the definition of Gross Asset Value;

(I) any valuation of non-cash Distributable Assets by the Board to the extent a distribution of non-cash assets is to be made by the Company pursuant to Section 4.4; and

(J) any significant change in the nature of the Company’s business.

(iv) Affiliate Transactions. In addition to the requirements set forth in Sections 3.3(a)(ii), any transaction by the Company or any of its Subsidiaries, on the one hand, and any Member or any Affiliates of any Member, on the other hand, shall require (x) Special Board Approval in connection with any such transaction involving the Summit Member(s) or their Affiliates and (y) the prior approval of a majority in voting power of the members of the Board who have not been appointed by the Member(s) or Affiliates of such Member(s) who are parties to the transaction in question in connection with any such transaction involving a Member (other than the Summit Member(s)) or Affiliates of a Member other than a Summit Member; provided, however, that no such additional approval pursuant to this Section 3.3(a)(iv) is required for:

(B) transactions with customers, clients, purchasers or sellers of goods or services (including the Members or any of their Affiliates), in each case, (i) in the Ordinary Course of Business and (ii) upon fair and reasonable terms no less favorable to the Company or its Subsidiary than would be obtainable in a comparable arm’s length transaction with a Person not a Member or an Affiliate of a Member.

(b) Proxy. Each Director entitled to vote at a meeting of the Board may authorize and appoint any other Director entitled to vote at such meeting to vote as his proxy for or on behalf of such Director. Each such authorization shall not require the consent or approval of any other Director (other than the Director being so authorized).

(c) Place, Waiver of Notice. Meetings of the Board may be held at such place or places as shall be determined from time to time by resolution of the Board. At all meetings of the Board, business shall be transacted in such order as shall from time to time be determined by resolution of the Board. Attendance of a Director at a meeting shall constitute a waiver of notice of such meeting, except where a Director attends a meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

(d) Regular Meetings. Regular meetings of the Board shall be held at such times and places as shall be designated from time to time by resolution of the Board. Notice of such meetings shall not be required; provided, however, that copies of each such resolution establishing the dates and times of such regular meetings shall be provided to each Director as promptly as practical following the adoption thereof.

(e) Special Meetings. Special meetings of the Board may be called on at least 48 hours notice to each Director by any Director. If Special Board Approval will be sought at such a meeting, such notice shall include that this is among the purposes of the special meeting. Except in an instance described in the foregoing sentence or as may otherwise be required by law or provided for in this Agreement, such notice need not state the purpose or purposes of, nor the business to be transacted at, such meeting.

(f) Notice; Telephone or Video Conference. Notice of any special meeting of the Board or other committee may be given personally, by mail, facsimile, courier, e-mail or other means and, if other than personally, shall be deemed given when written notice (including through e-mail) is delivered to the office of the Director (or his or her e-mail address, as applicable) at the address of the Director in the books and records of the Company. The Directors, or representatives of any committee designated by the Board, shall be entitled to participate in and hold a meeting of the Board or any such committee, as the case may be, by means of a telephone or video conference or similar communications equipment by means of which all Persons participating in the meeting can hear each other, and participation in such meeting shall constitute attendance and presence in person at such meeting, except where a Person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

SECTION 3.4. Approval or Ratification of Acts or Contracts. Any act or contract that shall be approved or be ratified by the Board (subject to the requirements of this Agreement) shall be as valid and as binding upon the Company and upon all the Members (in their capacity as Members) as if it shall have been approved or ratified by every Member of the Company.

SECTION 3.5. Action by Written Consent. Any action permitted or required by the Act, the Certificate or this Agreement to be taken at a meeting of the Board or any committee designated by the Board may be taken without a meeting if a consent in writing, setting forth the action to be taken, is signed by the Directors holding voting power of the Board or representatives of such committee, as the case may be sufficient to approve such action if a meeting of the Board or such committee were held to approve such action. Such consent shall

have the same force and effect as a vote at a meeting and may be stated as such in any document or instrument filed with the Secretary of State of Delaware, and the execution of such consent shall constitute attendance or presence in person at a meeting of the Board or any such committee, as the case may be; provided that unless written notice (including by e-mail) has been provided by the Company or the Chairman to each of the Directors then serving on the Board (to the address, facsimile number and/or e-mail address for each such Director as set forth in the books and records of the Company) at least 12 hours prior to execution of the written consent that the Board intends to submit for approval action by written consent of the Board (with such notice summarizing in reasonable detail the matters to be approved by written consent) or the Directors not executing such consent waive their right to such notice, no written consent of the Board shall be valid until 12 hours after such executed consent has been delivered to the Company, at which point the effectiveness of such consent shall be automatic, and provided that the Company and/or the Chairman gives prompt notice of any such action taken by written consent to the Directors or representatives of such committee who did not execute such written consent (provided that any failure to give such notice shall not affect the validity of any such action by written consent).

SECTION 3.6. Boards of Subsidiaries. The Company, the Board and each of its Members shall take such actions as are required so that the board of directors or similar governing body of each Subsidiary of the Company, if any, is, comprised of members in the same proportion and with the same voting power as applies to the Board, unless otherwise approved by Special Board Approval (or set forth in the governing organizational documents of such Subsidiary of the Company existing as of the date hereof).

SECTION 3.7. Officers.

(a) Designation and Appointment. The Board may, from time to time, employ and retain Persons as may be necessary or appropriate for the conduct of the Company’s business (subject to the supervision and control of the Board), including employees, agents and other Persons (any of whom may be a Member or Director) who may be designated as Officers of the Company, with titles including “chief executive officer,” “chairman,” “president,” “vice president,” “treasurer,” “secretary,” “director” and “chief financial officer,” as and to the extent authorized by the Board. Any number of offices may be held by the same Person. In its discretion, the Board may choose not to fill any office for any period as it may deem advisable. Officers need not be Members or residents of the States of Delaware or Missouri. Any Officers so designated shall have such authority and perform such duties as the Board may, from time to time, delegate to them. The Board may assign titles to particular Officers. Each Officer shall hold office until his or her successor shall be duly designated and shall qualify or until his or her death or until he or she shall resign or shall have been removed in the manner hereinafter provided. The salaries or other compensation, if any, of the Officers of the Company shall be fixed from time to time by the Board.

(b) Resignation/Removal. Any Officer may resign as such at any time. Such resignation shall be made in writing and shall take effect at the time specified therein, or if no time be specified, at the time of its receipt by the Board. The acceptance of a resignation shall not be necessary to make it effective, unless expressly so provided in the resignation. Any Officer may be removed as such, either with or without cause at any time by the Board. Designation of an Officer shall not of itself create any contractual or employment rights.

(c) Duties of Officers Generally. The Officers, in the performance of their duties as such, shall owe to the Company duties of loyalty and due care of the type owed by the officers of a corporation to such corporation and its stockholders under the laws of the State of Delaware.

(d) Chief Executive Officer. Subject to the powers of the Board, the chief executive officer of the Company shall be in general and active charge of the entire business and affairs of the Company, and shall be its chief policy making officer. The chief executive officer shall initially be R. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇.

(e) Vice President of Finance and Administration. The Vice President of Finance and Administration shall keep and maintain, or cause to be kept and maintained, adequate and correct books and records of accounts of the properties and business transactions of the Company, including accounts of its assets, liabilities, receipts, disbursements, gains, losses and capital. The Vice President of Finance and Administration shall have the custody of the funds and securities of the Company, and shall keep full and accurate accounts of receipts and disbursements in books belonging to the Company, and shall deposit all moneys and other valuable effects in the name and to the credit of the Company in such depositories as may be designated by the Board. The Vice President of Finance and Administration shall have such other powers and perform such other duties as may from time to time be prescribed by the chief executive officer or the Board. The Vice President of Finance and Administration shall initially be ▇▇▇▇ ▇▇▇▇▇▇▇▇.

(f) Senior Vice President. The Senior Vice President shall be in general and active charge over the sale of Company products and services to the Company’s customers. The Senior Vice President shall initially be ▇▇▇▇▇▇ ▇▇▇▇.

SECTION 3.8. Management Matters. (a) All property owned by the Company shall be registered in the Company’s name, in the name of a nominee or in “street name” as the Board may from time to time determine.

(b) The Board may take all action which may be necessary or appropriate (i) for the continuation of the Company’s valid existence as a limited liability company under the laws of the State of Delaware (and of each other jurisdiction in which such existence is necessary to enable the Company to conduct the business in which it is engaged) and (ii) for the maintenance, preservation and operation of the business of the Company in accordance with the provisions of this Agreement and applicable laws and regulations. The Board may file or cause to be filed for recordation in the office of the appropriate authorities of the State of Delaware, and in the proper office or offices in each other jurisdiction in which the Company is formed or qualified, such certificates (including certificates of limited liability companies and fictitious name certificates) and other documents as are required by the applicable statutes, rules or regulations of any such jurisdiction or as are required to reflect the identity of the Members and the amounts of their respective capital contributions.

SECTION 3.9. Liability to Members.

(a) Except as otherwise required by applicable law and as expressly set forth in this Agreement, no Member shall have any personal liability whatsoever in such Member’s capacity as a Member, whether to the Company, to any of the other Members, to the creditors of the Company or to any other third party, for the debts, liabilities, commitments or any other obligations of the Company or for any losses of the Company (other than any losses of the Company arising from a material breach of this Agreement by such Member). Each Member shall be liable only to make such Member’s Capital Contribution to the Company and the other payments provided expressly herein.

(b) In accordance with the Act and the laws of the State of Delaware, a member of a limited liability company may, under certain circumstances, be required to return amounts previously distributed to such Member. It is the intent of the Members that no distribution to any Member pursuant to Article IV hereof shall be deemed a return of money or other property paid or distributed in violation of the Act. The payment of any such money or distribution of any such property to a Member shall be deemed to be a compromise for purposes of §18-502(b) of the Act, and the Member receiving any such money or property shall not be required to return to any Person any such money or property. However, if any court of competent jurisdiction holds that, notwithstanding the provisions of this Agreement, any Member is obligated to make any such payment, such obligation shall be the obligation of such Member and not of any Director or other Member.

SECTION 3.10. Fiduciary Duties.

(a) Notwithstanding anything to the contrary in this Agreement or at law or in equity including but not limited to the Act, each Member agrees that any fiduciary duty imposed under Delaware law (including the duty of loyalty and the duty of care) on a Member or any Director shall be defined, limited and eliminated as provided in this Section 3.10.

(b) Certain Potential Conflicts. Each Member acknowledges that:

(i) each Member and its Affiliates may engage in material business transactions with the Company or its Subsidiaries, subject to the requirements of Section 3.3(a)(iv); and

(ii) the directors, officers and/or employees of a Member and its Affiliates may serve as directors, officers and/or employees of the Company or its Subsidiaries.

(c) Limitation of Liability. To the fullest extent permitted by law, no Member or its Affiliates or any director, officer or employee of any Member or its Affiliates who may serve as a director of the Company or its Subsidiaries shall be liable to the Company or its Subsidiaries:

(i) by reason of any business decision or transaction undertaken by such Member or its Affiliates which may be adverse to the interests of the Company or its Subsidiaries (provided that such transaction is not in violation of Section 3.3(a)(iv));

(ii) by reason of any activity undertaken by such Member or its Affiliates or by any other Person in which such Member or its Affiliates may have an investment or other financial interest which is in competition with the Company or its Subsidiaries; or

(iii) by reason of any transaction with such Member or its Affiliates, or any transaction in which such Member or its Affiliates shall have a financial interest, unless (x) the party seeking to assert such liability shall prove, by clear and convincing evidence, that such transaction could not have been the product of rational business judgment at the time and under the circumstances it was authorized by the Board or a committee thereof and (y) the transaction has not otherwise been approved by Special Board Approval (and provided that such transaction is not in violation of Section 3.3(a)(iv)).

(d) Competing Activities. If any Member or an Affiliate thereof acquires knowledge of a potential transaction or matter which may be an investment or business opportunity or prospective economic or competitive advantage in which the Company could have an interest or expectancy (a “Competitive Opportunity”) or otherwise is then exploiting any Competitive Opportunity, the Company (and the Company’s Subsidiaries) will have no interest in, and no expectation that, such Competitive Opportunity be offered to it, any such interest or expectation being hereby renounced so that such Member shall (i) have no duty to communicate or present such Competitive Opportunity to the Company (or its Subsidiaries) unless the Competitive Opportunity is or would be principally related to a business that is both (x) presently conducted by the Company or its Subsidiaries and (y) principally located within the market areas served by the Company within the States of Missouri, Illinois and and/or Iowa, in which case such Member or its Affiliate, as applicable, shall be required to disclose such Competitive Opportunity to the Board (but shall not otherwise be obligated to present or otherwise assign or transfer such Competitive Opportunity to the Company or its Affiliates and neither such Member or any of its Affiliates shall be deemed to have relinquished any right or interest in such Competitive Opportunity by virtue of the foregoing) and (ii) have the right to hold any such Competitive Opportunity for such Member’s (and its agents’, partners’ or Affiliates’) own account and benefit, or to recommend, assign or otherwise transfer or deal in such Competitive Opportunity to Persons other than the Company or any Affiliate of the Company. For the avoidance of doubt, this Section 3.10(d) shall not limit the Company’s independent ability to pursue a Competitive Opportunity. Without limiting the generality of the foregoing, each Member acknowledges that (i) a Member or its Affiliates may engage or invest in, independently or with others, any business activity of any type or description, including those that might be the same as or similar to the Company’s business, and which from time to time compete, directly or indirectly, with the Company, and the Member and their respective Affiliates may in their sole discretion pursue such competing business without disclosure of such competition to the

Company (or any Subsidiary of the Company) except as provided above and (ii) neither the Company, any Subsidiary of the Company nor any other Member shall have any right in or to the activities described in clause (i) or to receive or share in any income or proceeds derived therefrom. In connection with any Competitive Opportunity disclosed to the Board as required by this Section 3.10(d), the Company and the Directors shall agree to adhere to any obligations of confidentiality to which the disclosing Member or its Affiliate(s) are subject with respect to such Competitive Opportunity.

ARTICLE IV

CAPITAL CONTRIBUTIONS;

ALLOCATIONS; DISTRIBUTIONS

SECTION 4.1. Recapitalization; Initial Units; Capital Contributions.

(a) Upon execution of this Agreement on the date hereof, all limited liability company interests held by each Rollover Member pursuant to the Original Agreement shall automatically and without further action by the Company or any Member or other Person be converted into the number of Class B Units set forth opposite such Member’s name on Schedule I (as it exists as of the date hereof) (the “Recapitalization”).

(b) Each Person set forth on Schedule I (as it exists as of the date hereof) other than the Rollover Members has agreed to make an initial capital contribution to the Company consisting of cash in the respective amounts and in exchange for the respective number and type of Units set forth on Schedule I to this Agreement (as it exists as of the date hereof) pursuant to the Subscription Agreement. The Company shall issue to each Member (other than the Rollover Members) the respective number and type of Units set forth on Schedule I to this Agreement (opposite the name of such Member) upon execution of this Agreement by such Member and the payment or delivery of such Member’s Capital Contribution in the amount set forth on Schedule I.

(c) No Member shall be required to make any Capital Contributions without such Member’s consent except as set forth in Section 4.1(b). No Member shall be permitted to make any Capital Contributions except with the prior approval of the Board and otherwise in accordance with the terms of this Agreement (including, to the extent applicable, Section 3.3(a)(iii)).

SECTION 4.2. Capital Accounts. (a) There shall be established for each Member on the books of the Company a Capital Account which shall be increased or decreased in the manner set forth in this Agreement.

(b) A Member shall not have any obligation to the Company or to any other Member to restore any negative balance in the Capital Account of such Member.

SECTION 4.3. Allocations of Net Income and Net Loss.

(a) Timing and Amount of Allocations of Net Income and Net Loss. Net Income and Net Loss of the Company (and, to the extent necessary, individual items of income, gain, loss or deduction of the Company) shall be determined and allocated with respect to each fiscal year of the Company as of the end of each such year or as circumstances otherwise require or allow. Subject to the other provisions of this Section 4.3, an allocation to a Member of a share of Net Income or Net Loss shall be treated as an allocation of the same share of each item of income, gain, loss or deduction that is taken into account in computing Net Income or Net Loss. Notwithstanding anything in this Section 4.3 to the contrary (or in any other section of this Agreement), and except as otherwise required by any applicable provision of the Code or Regulation, the Rollover Members shall be allocated Net Income and Net Loss of the Company (and, to the extent necessary, individual items of income, gain, loss or deduction of the Company) as follows: (i) from January 1 through April 30, 2010 using the interim-closing-of-the-books method, and (ii) for purposes of convenience, from May 1, 2010 through and including the Closing Date by allocating such items to the Rollover Members for May, 2010 based on the number of days elapsed from May 1, 2010 through and including the Closing Date relative to 31.

(b) General Allocations. Except as otherwise provided in this Agreement, all Net Income and Net Loss shall be allocated in a manner such that the Capital Account of each Member after giving effect to the allocations set forth in Section 4.3(c) is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made to such Member pursuant to Section 4.4(a)(ii) if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Gross Asset Value (determined, for the avoidance of doubt, without adjustment for the hypothetical liquidation described in this Section 4.3(b)), all Company liabilities were satisfied (limited with respect to each nonrecourse liability to the Gross Asset Value of the assets securing such liability) and the net assets of the Company were distributed in accordance with Section 4.4(a)(ii) to the Members immediately after making such allocation, minus (ii) such Member’s share of Company Minimum Gain and Member Minimum Gain, computed immediately prior to the hypothetical sale of assets.

(i) Regulatory Allocations.

(A) If there is a net decrease in Company Minimum Gain or Member Minimum Gain during any fiscal year, the Members shall be allocated items of Company income and gain for such year (and, if necessary, for subsequent years) in accordance with Regulations Section 1.704-2(f) or 1.704-2(i)(4), as applicable. It is intended that this Section 4.3(c)(i)(A) qualify and be construed as a “minimum gain chargeback” and a “chargeback of partner nonrecourse debt minimum gain” within the meaning of such Regulations, which shall be controlling in the event of a conflict between such Regulations and this Section 4.3(c)(i)(A).

(B) Any Nonrecourse Deductions for any fiscal year shall be specially allocated to the Members in accordance with the number of their Units. Any Member Nonrecourse Deductions for any fiscal year shall be specially allocated to the Member(s) who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable, in accordance with Regulations Section 1.704-2(i).

(C) If any Member unexpectedly receives an adjustment, allocation or distribution described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall be allocated, in accordance with Regulations Section 1.704-1(b)(2)(ii)(d), to the Member in an amount and manner sufficient to eliminate, to the extent required by such Regulations, the Adjusted Capital Account Deficit of the Member as quickly as possible. It is intended that this Section 4.3(c)(i)(C) qualify and be construed as a “qualified income offset” within the meaning of Regulations 1.704-1(b)(2)(ii)(d), which shall be controlling in the event of a conflict between such Regulations and this Section 4.3(c)(i)(C).

(D) The allocations set forth in Sections 4.3(c)(i)(A), (B) and (C) (the “Regulatory Allocations”) are intended to comply with certain regulatory requirements, including the requirements of Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding the provisions of Section 4.3(b), the Regulatory Allocations shall be taken into account in allocating other items of income, gain, loss and deduction among the Members so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Member shall be equal to the net amount that would have been allocated to each such Member if the Regulatory Allocations had not occurred.

(ii) For any fiscal year during which a Member’s interest in the Company is assigned by such Member (or by an assignee or successor in interest to a Member), the portion of the Net Income and Net Loss of the Company that is allocable in respect of such Member’s interest shall be apportioned between the assignor and the assignee of such Member’s interest using any permissible method under Code Section 706 and the Regulations thereunder (consistently applied to all Members), as determined by the Tax Matters Member.

(iii) In the event that any amount claimed by the Company to constitute a deductible expense in any fiscal year is treated for federal income tax purposes as a distribution made to a Member in its capacity as a member of the Company and not a payment to a Member not acting in its capacity as a partner under Code Section 707(a), then the Member who is deemed to have received such distribution shall first be allocated an amount of Company gross income equal to such payment, its Capital Account shall be reduced to reflect the distribution, and for purposes of Section 4.3, Net Income and Net Loss shall be determined after making the allocation required by this Section 4.3(c)(iii).

(iv) In the event that any amount claimed by the Company to constitute a distribution made to a Member in its capacity as a member of the Company is treated for federal income tax purposes as a deductible expense of the Member for a payment to a Member not acting in its capacity as a member of the Company, then the Member who is deemed to have received such payment shall first be allocated the Company expense item attributable to such payment, its Capital Account shall be reduced to reflect the allocation, and for purposes of Section 4.3, Net Income and Net Loss shall be determined after making the allocation required by this Section 4.3(c)(iv).

(d) Required Tax Allocations. All items of income, gain, loss, deduction and credit for federal income tax purposes shall be allocated to each Member in the same manner as the Net Income or Net Loss (and each item of income, gain, loss and deduction related thereto) that is allocated to such Member pursuant to Section 4.3(a), (b) and (c) to which such tax items relate. Notwithstanding the foregoing provisions of this Section 4.3, income, gain, loss and deduction with respect to property contributed to the Company by a Member shall be shared among the Members for federal, state and local income tax purposes pursuant to Regulations promulgated under Section 704(c) of the Code, so as to take account of the variation, if any, between the basis of the property to the Company and its initial Gross Asset Value (using such method determined by the Tax Matters Partner and permitted under the Regulations). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (b), (c), or (d) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss and deduction with respect to such asset shall take account of the variation, if any, between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and related Regulations. Any elections or other decisions relating to allocations under this Section 4.3(d) will be made in any manner that the Tax Matters Member determines in its sole discretion reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 4.3(d) are solely for purposes of federal, state and local income taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Net Income, Net Loss, other tax items or distributions pursuant to any provision of this Agreement.

(e) Excess Nonrecourse Liabilities. Solely for purposes of determining a Member’s share of the “excess nonrecourse liabilities” of the Company, within the meaning of Treasury Regulation Section 1.752-3(a)(3), the Members’ interests in Company profits are in proportion to the number of their Units.

(f) Members’ Tax Reporting. The Members acknowledge and are aware of the income tax consequences of the allocations made by Section 4.3 and, except as may otherwise be required by applicable law or regulatory requirements, hereby agree to be bound by the provisions of Section 4.3 in reporting their shares of Company income, gain, loss and deductions for federal, state and local income tax purposes.

(g) Withholding. To the extent the Company is required by law to withhold or to make Tax payments on behalf of or with respect to any Member (“Tax Advances”), the Company may withhold such amounts and make such Tax payments as so required. All Tax

Advances made on behalf of a Member shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Member. If a distribution to a Member is actually reduced as a result of a Tax Advance, for all other purposes of this Agreement such Member shall be treated as having received the amount of the distribution that is reduced by the Tax Advance. Each Member hereby agrees to indemnify and hold harmless the Company and the other Members from and against any liability (including any liability for Taxes, penalties, additions to Tax or interest) with respect to income attributable to or distributions or other payments to such Member.

SECTION 4.4. Distributions. (a) The timing of all distributions of Distributable Assets will be at the sole discretion of the Board. When a distribution is authorized by the Board, each Member’s allocable portion of Distributable Assets, subject to Sections 4.4(b), (c) and (d), will be distributed as follows:

(i) If such distribution is not in connection with the complete liquidation and dissolution of the Company pursuant to Section 7.2, 100% of the Distributable Assets shall be distributed to the Members on a pari passu basis, as follows:

(A) there shall be distributed to each Class A Member in respect of its Class A Units a percentage of such Distributable Assets equal to the product of (1) the Class A Sharing Percentage and (2) a fraction, the numerator of which is the number of Class A Units held by such Class A Member at the time of such distribution and the denominator of which is the aggregate number of outstanding Class A Units; and

(B) there shall be distributed to each Class B Member in respect of its Class B Units a percentage of such Distributable Assets equal to the product of (1) the Class B Sharing Percentage and (2) a fraction, the numerator of which is the number of Class B Units held by such Class B Member at the time of such distribution and the denominator of which is the aggregate number of outstanding Class B Units.

(ii) To the extent that such distribution is made in connection with the complete liquidation and dissolution of the Company pursuant to Section 7.2, the distribution shall be made either (x) in the manner specified in Section 4.4(a)(i) above or (y) in the manner specified below based upon whichever allocation will provide the greatest return to the Class A Members in respect of their Class A Units in connection with such distribution (and any reference to Section 4.4(a)(ii) in this Agreement shall be interpreted accordingly unless expressly stated otherwise):

(A) First, 100% of the Distributable Assets shall be distributed to the Class A Members, pro rata based upon each Class A Member’s Class A Units until the Class A Members have received cumulative distributions pursuant to Section 4.4(a)(i)(A) (but without duplicating any amounts that were taken into account in calculating the amounts distributable pursuant to Section 4.4(a)(ii)(B)) and this Section 4.4(a)(ii)(A) equal to each such Member’s Class A Priority Return Amount attributable to the Class A Units held by it;

(B) Second, 100% of the Distributable Assets shall be distributed to the Class A Members, pro rata in proportion to the amount of their Capital Contributions made in exchange for Class A Units until the Class A Members have received cumulative distributions pursuant to Section 4.4(a)(i)(A) (but without duplicating any amounts that were taken into account in calculating the amounts distributable pursuant to Section 4.4(a)(ii)(A)) and this Section 4.4(a)(ii)(B) equal to each such Member’s aggregate Capital Contributions made in exchange for Class A Units held by it; and

(C) Third, 100% of the Distributable Assets shall be distributed to the Class B Members, pro rata in accordance with the number of each Class B Member’s Class B Units; provided, however, that if as a result of any such distribution pursuant to this Section 4.4(a)(ii) the Class B Members would have received but for this proviso distributions pursuant to Section 4.4(a)(i)(B), Section 4.4(c) and this Section 4.4(a)(ii) in an aggregate amount in excess of the amount that the Class B Members would have received had all such distributions been made at the time of the complete liquidation and dissolution of the Company pursuant to Section 7.2, as applicable, solely pursuant to Section 4.4(a)(i)(B) based upon the Class B Sharing Percentage as it exists at the time of such liquidation and dissolution, then any such excess amount shall not be distributed to the Class B Members in respect of their Class B Units but shall instead be distributed to the Class A Members, pro rata in accordance with the number of each Class A Member’s Class A Units;

provided that, if the Distributable Assets being distributed consist of more than one kind of asset, all Distributable Assets shall be allocated as determined on a good faith basis by the Board, and in the case of a distribution pursuant to this Section 4.4 of non-cash Distributable Assets, any determination by the Board as to the value of such Distributable Assets shall be subject to Special Board Approval pursuant to Section 3.3(a)(iii)(I).

Notwithstanding the foregoing, in the event of the Rollover Exchange or exercise of the Put Right where, following the consummation of the purchase or exchange of the Class B Units as contemplated in Sections 5.5 or 5.6, as applicable, certain of the Class B Units remain outstanding, then the definition of Class A Sharing Percentage, Class B Sharing Percentage, Sharing Percentage and any related terms and this Section 4.4 shall be amended by the Company and the Members to appropriately adjust such definitions and this Section 4.4 to take into account such purchase or exchange.

(b) For purposes of determining the amount of distributions under this Section 4.4, any holder of a Membership Interest (or any portion thereof), whether or not such Person is a Substitute Member, shall be treated as having received amounts received by its predecessors or successors in interest.

(c) If the distributions made to a Member under Section 4.4(a) are not sufficient to permit a Member (or its beneficial owners) to pay when due its income taxes attributable to taxable income of the Company allocated to such Member for a taxable year (after giving effect to any net cumulative taxable losses from prior taxable years (“Net Taxable Income”)), the Board shall, to the extent that there are Distributable Assets in the form of cash (and provided that such payments would not cause a default, event of default, breach, non-compliance or failure to satisfy any financial ratio or covenant by the Company or any of its Subsidiaries under any agreement whereby the Company and/or its Subsidiaries are obligated to repay indebtedness in excess of Five Million Dollars, including any credit agreement, indenture, security agreement or similar agreement governing such indebtedness of the Company or any of its Subsidiaries or render the Company insolvent, Bankrupt or otherwise incapable of satisfying its and its Subsidiaries’ liabilities as they become due), cause the Company in no event later than 90 days after the close of each fiscal year, to make a distribution (a “tax distribution”) to such Member so that aggregate distributions to such Member pursuant to this Section 4.4(c) (taking into account any distributions made to such Member to pay estimated taxes) for each fiscal year (other than tax distributions to a Member made during a fiscal year in respect of income allocable to such Member in a prior fiscal year), equal the federal, state and local income tax liability that would be payable in respect of the taxable income allocable to such Member (without regard to any taxable income allocable as a result of Code Section 704(c)) determined (A) solely by reference to such Member’s allocable share of the Company’s income, (B) as if such Member were an individual resident in New York, New York, (C) as if such Member were subject to federal, state and local income tax at the highest marginal rate then in effect, taking into account the character of such income and the deductibility of state and local taxes and (D) reducing such taxable income by prior year Net Losses with respect to the Company allocable to such Member. If a Member holds more than one class of Units, then such Member’s tax distributions shall be determined separately with respect to each class of Units held by such Member, and solely with respect to allocations of taxable items to such Member in respect of such class of Units. A tax distribution to a Member in respect of any Unit shall be charged against current or future distributions to which such Member would otherwise have been entitled under Section 4.4(a) or Section 7.2 in respect of such Unit. In addition to the annual tax distribution required by this Section 4.4(c), the Company shall, to the extent of available cash, make periodic distributions to the Members (to the extent that there are Distributable Assets in the form of cash) in amounts sufficient for the Members to pay estimated taxes, calculated in accordance with the principles set forth in this Section 4.4(c).

(d) If all or a portion of a Member’s Units are transferred, sold or otherwise disposed of (including pursuant to a redemption by the Company), then subsequent distributions (i) to the transferor Member pursuant to this Agreement shall be determined without regard to amounts previously distributed to such transferor Member in respect of the Units so transferred, sold or otherwise disposed and (ii) to the transferee member pursuant to this Agreement shall be determined with regard to amounts previously distributed to the transferor Member.

(e) For the avoidance of doubt, no management or other advisory fees or expense reimbursement payable to a Member or its Affiliates by the Company shall be deemed to be a distribution for purposes of this Section 4.4.

SECTION 4.5. Security Interest and Right of Set-Off. As security for any withholding tax, the Company shall have (and each Member hereby grants to the Company) a security interest in all Distributable Assets distributable to such Member to the extent of the amount of such withholding tax. The Company shall have a right of set-off against such distributions of Distributable Assets in the amount of such withholding tax. The Company may withhold distributions or portions thereof if it is required to do so by the Code or any other provision of federal, state or local tax or other law. Any amount withheld pursuant to the Code or any other provision of federal, state or local tax or other law with respect to any distribution to a Member shall be treated as an amount distributed to such Member for all purposes under this Agreement.

SECTION 4.6. Additional Issuances Generally.

(a) If the Company proposes to issue additional equity securities (including securities exercisable for or convertible into equity securities), the Company shall deliver to each Class A Member and Class B Member (each, a “Participating Member”, and, collectively, the “Participating Members”) a written notice of such proposed issuance at least thirty (30) days prior to the date of the proposed issuance (the period from the effectiveness pursuant to Section 10.8 of such notice until the date of such proposed issuance, the “Subscription Period”). Such notice shall include (i) the amount, kind and terms of the equity securities to be included in the issuance, (ii) the maximum and minimum price per unit of the equity securities to be included in the issuance, (iii) the name and address of the proposed purchaser and (iv) the proposed issuance date, if known.

(b) Each Participating Member shall have the option, exercisable at any time during the first twenty (20) days of the Subscription Period by delivering written notice to the Company, to irrevocably subscribe for not more than its Sharing Percentage (based on the Units then held by such Participating Member) of any such additional equity securities (including securities exercisable for or convertible into equity securities), on the same terms as those of the proposed issuance of such additional equity securities (including securities exercisable for or convertible into equity securities). Each Participating Member who does not exercise such option in accordance with the above requirements shall be deemed to have waived all of such Participating Member’s rights with respect to such issuance. In the event that any Participating Member does not elect to purchase its aggregate Sharing Percentage of the additional equity securities (including securities exercisable for or convertible into equity securities), the Company shall deliver to each Participating Member (other than declining Participating Members) a written notice thereof not later than the twenty-fifth day of the Subscription Period, including the number of equity securities which were subject to the purchase right of such declining Participating Member(s), and each other Participating Member may subscribe for not more than its Sharing Percentage (calculated excluding the Sharing Percentage attributable to the declining Members) of such declined equity securities before the expiration of the Subscription Period.

(c) If, prior to consummation, the terms of the proposed issuance shall change with the result that the price shall be less than the minimum price set forth in the notice contemplated by clause (a) above or the other principal terms shall be more favorable to the prospective purchaser than those set forth in such notice, it shall be necessary for a separate notice to be furnished, and the terms and provisions of this Section 4.6 separately complied with.

(d) If at the end of the 90th day after the date of the effectiveness of the notice contemplated by clause (a) above as such period may be extended to obtain any required regulatory approvals, the Company has not completed the issuance, each Participating Member shall be released from such Participating Member’s obligations under the written commitment, the notice shall be null and void, and it shall be necessary for a separate notice to be furnished, and the terms and provisions of this Section 4.6 separately complied with, in order to consummate such issuance.

(e) In the event that the participation in the issuance by a Participation Member as a purchaser would require under applicable law (i) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required for the issuance or (ii) the provision to any participant in the issuance of any specified information regarding the Company or any of its Subsidiaries or the securities to be issued that is not otherwise required to be provided for the issuance, such Participation Member shall not have the right to participate in the issuance.

(f) Each Participating Member shall take or cause to be taken all such reasonable actions as may be necessary or reasonably desirable in order expeditiously to consummate each issuance pursuant to this Section 4.6.

(g) Notwithstanding the requirements of this Section 4.6, the Company may proceed with any issuance prior to having complied with the provisions of this Section 4.6 so long as the Company has used reasonable best efforts to give all Class A Members and Class B Members, including the Rollover Members, the opportunity to invest in the issuance; provided that the Company shall:

(i) provide to each Member in connection with such issuance (A) with prompt notice of such issuance and (B) the notice described in clause (a) above in which the actual price per unit of the equity securities shall be set forth;

(ii) offer to issue to each such Member such number of securities of the type issued in the issuance as may be requested by such Member (up to a number of securities that would be necessary for such Member to maintain the Sharing Percentage to which such Member would have been entitled to pursuant to Section 4.6(b) (assuming full participation by all Participating Members) on the same economic terms and conditions with respect to such securities as the subscribers in the issuance received; and

(iii) keep such offer open for a period of twenty (20) business days, during which period each such Member may accept such offer by sending a written acceptance to the Company committing to purchase an amount of such securities (not in any event in excess of the number contemplated by Section 4.6(g)(ii)).

(h) The provisions of this Section 4.6 shall not apply to issuances by the Company as follows:

(i) any issuance to the Company or any wholly-owned Subsidiary of the Company;

(ii) any issuance of securities upon the exercise or conversion of any stock, options, warrants or convertible securities outstanding on the date hereof or issued after the date hereof in a transaction that complied with the provisions of this Section 4.6 (other than those described in clause (iii) immediately below);

(iii) any issuance of Units or other equity securities, options, warrants or convertible securities (and Units underlying such securities) to officers, employees, directors, agents or consultants (other than a Member or an Affiliate thereof, excluding R. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇) of the Company or its subsidiaries in connection with such Person’s employment or consulting arrangements with the Company or its subsidiaries, in each case to the extent approved by the Board or pursuant to an employment benefit plan or arrangement approved by the Board;

(iv) any issuance of equity securities, options, warrants or convertible securities, in each case to the extent approved by the Board and subject to Section 3.3(a)(iii)(D) to the extent applicable, (A) in connection with any business combination or acquisition transaction by or involving the Company or any of its Subsidiaries, including a Change of Control or other Exit Event, (B) in connection with any joint venture or strategic partnership entered into primarily for purposes other than raising capital (as determined by the Board in its sole discretion) or (C) to financial institutions, commercial lenders, broker/finders or any similar party, or their respective designees, in connection with the incurrence or guarantee of indebtedness by the Company or any of its subsidiaries;

(v) any issuance of equity securities pursuant to a public offering;

(vi) the issuance of Units to the Members on the date hereof pursuant to Section 4.1(b) or in connection with the Recapitalization and the transactions contemplated by the Subscription Agreement; or

(vii) any issuance of securities in connection with any Unit split, Unit dividend paid on a proportionate basis to all holders of the affected class of Units or recapitalization, in each such case, approved by the Board.

ARTICLE V

ADMISSION OF NEW MEMBERS

SECTION 5.1. Admission of Additional or Substitute Members.

(a) The Board shall have the right, in its sole and absolute discretion, to admit as an Additional Member any Person who acquires an interest in the Company, including Units or any other Membership Interest. Concurrently with the admission of an Additional Member, the Board shall forthwith cause any necessary papers to be filed and recorded and notice to be given wherever and to the extent required showing the admission of an Additional Member, all at the expense, including payment of any professional and filing fees incurred, of the Additional Member.

(b) The Board shall have the right, in its sole and absolute discretion (other than as provided in Section 5.1(d)), to admit as a Substitute Member any Person who acquires a Membership Interest, including Unit(s), from a Member in accordance with this Article V and such Substitute Member shall succeed to the Membership Interest acquired from such Member. Concurrently with the admission of a Substitute Member, the Board shall forthwith cause any necessary papers to be filed and recorded and notice to be given wherever and to the extent required showing the substitution of a transferee as a Substitute Member in place of the transferring Member, all at the expense, including payment of any professional and filing fees incurred, of the Substitute Member.

(c) The admission of any Person as a Substitute or Additional Member shall be conditioned upon (i) such Person’s written acceptance and adoption of all the terms and provisions of this Agreement, either by (X) execution and delivery of a counterpart signature page to this Agreement countersigned by the Board or a duly authorized designee of the Board on behalf of the Company or (Y) any other writing evidencing the intent of such Person to become a Substitute Member or Additional Member and such writing is accepted by the Board on behalf of the Company and (ii) upon the request of the Board, such Person’s execution and delivery of such other documentation as the Board may reasonably require in connection with the issuance or Transfer of interests in the Company and the admittance of such Person as a Member.

(d) Notwithstanding anything herein to the contrary, upon exercise of their remedies pursuant to Section 8.02 of the First Lien Credit Agreement or the eleventh paragraph of the Membership Interests Pledge Agreements to the extent an Event of Default (as defined in such paragraph of the Membership Interest Pledge Agreements) has occurred under the Membership Interest Pledge Agreements and provided (x) the agent or the lenders have provided five business days’ prior notice to the Company and the Members of its or their intention to exercise such remedies and (y) such exercise of remedies is not being disputed in good faith by the Company or any Member, and subject to compliance with Section 5.1(c)(i) above (other than any requirement for any countersignature or acceptance by the Board), the agent and the lenders

under the First Lien Credit Agreement (or their assignees or designees) without any further action by the Board or the Members, shall have the right to acquire the Units pledged pursuant to the First Lien Credit Agreement in connection with the enforcement of their rights under Section 8.02 of the First Lien Credit Agreement or the eleventh paragraph of the Membership Interests Pledge Agreements, to become a transferee of such pledged Units and correspondingly become a Substitute Member and/or to exercise the rights of a Member hereunder with respect to such pledged Units.

SECTION 5.2. Transfers Generally.

(a) Except as provided in Sections 2.9(f), 5.1(d), 5.3, 5.4, 5.5 and 5.6(b)(i), in connection with a Transfer of Units to a Permitted Transferee of such Member or in connection with a pledge of Units pursuant to the First Lien Credit Agreement or Second Lien Credit Agreement, no Member other than the Summit Member(s) and their Permitted Transferees may, directly or indirectly, transfer, sell, exchange, mortgage, hypothecate, pledge, assign, securitize or otherwise dispose of (any of the foregoing, a “Transfer”) all or part of such Member’s Membership Interest prior to the fifth anniversary of the Closing Date without the prior written consent of the Board, which consent may be given or withheld in its sole discretion. From and after the fifth anniversary of the Closing Date, the Members other than the Summit Member(s) shall be entitled to Transfer their Units, subject to compliance with this Section 5.2. The Summit Member(s) may Transfer their Membership Interests at any time, subject to compliance with Section 5.3 and/or Section 3.3(a)(iii)(B), in each case, to the extent applicable.

(b) Notwithstanding anything in this Agreement to the contrary, without the prior written consent of the Board, no issuance or Transfer of Units otherwise permitted or required shall be made:

(i) unless such issuance or Transfer is in compliance with applicable law, including U.S. federal and applicable state securities laws, including the Securities Act and the rules and regulations thereunder. If any such Transfer is made pursuant to an exemption from the U.S. federal and state securities laws, such Transfer shall be made only (unless the Board otherwise waives in writing such requirement) upon the transferee first having delivered to the Company a favorable written opinion of counsel, reasonably satisfactory in form and substance to the Board, to the effect that the proposed Transfer is exempt from registration under the Securities Act and any applicable state securities laws; provided, however, that no such opinion of counsel shall be required for (A) a Transfer by a Member to a Permitted Transferee made in accordance with the terms of this Agreement; (B) a sale duly made in compliance with Rule 144 promulgated under the Securities Act, or any successor or analogous rule to Rule 144, or if the Member would be permitted to Transfer the securities pursuant to paragraph (d)(1) of Rule 144 (it being agreed that the Company shall have the right to receive evidence reasonably satisfactory to it regarding compliance with such Rule or any successor or analogous rule prior to the registration of any such Transfer); or (C) a Transfer pursuant to an effective registration statement;

(ii) for so long as the Company is a partnership for United States federal income tax purposes, if such Transfer 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 such Transfer would otherwise result in the Company being treated as a “publicly traded partnership,” as such term is defined in Sections 469(k)(2) or 7704(b) of the Code and the regulations promulgated thereunder;

(iii) if such issuance or Transfer subjects the Company to be regulated under the Investment Company Act of 1940 or the Investment Advisors Act of 1940; or

(iv) if such issuance or Transfer would cause (A) all or any portion of the assets of the Company to (i) constitute “plan assets” (for purposes of Title I of ERISA, Section 4975 of the Code or any applicable Similar Law) of any existing or contemplated Member, or (ii) be subject to the provisions of Title I of ERISA, Section 4975 of the Code or any applicable Similar Law, or (B) the Board or any Member (in its capacity as such) to become a fiduciary with respect to any existing or contemplated Member, pursuant to ERISA, any applicable Similar Law or otherwise.

(c) No Transfer of Interests otherwise permitted by this Agreement shall be effective unless and until any transferee who is not already a Member has complied with the requirements of Section 5.1(c) and such Person has otherwise been admitted to the Company as a Substitute Member (including pursuant to Section 5.1(d) to the extent applicable).

(d) The Members shall be permitted to assign or transfer any rights granted to such Members (or group of Members) hereunder in connection with any Transfer of Units by such Members (including any right to appoint Directors), provided that any such assignment or transfer of rights shall be proportionate to the number of Units so Transferred. To the extent that any Members so assign or transfer such rights, the Company and each of the Members shall enter into an amendment to this Agreement to appropriately reflect the assignment of such rights in accordance with the intent of this Section 5.2(d).

(e) To the extent that following a Transfer to a Permitted Transferee the status of such Permitted Transferee changes such that such transferee would no longer constitute a Permitted Transferee of the transferor, such original Transfer shall be deemed null and void ab initio.

(f) Any Transfer or attempted Transfer of any Units or Membership Interests in violation of any provision of this Agreement shall be void, and the Company shall not record such Transfer on its books or treat any purported transferee of such Units or Membership Interests as the owner of such Units or Membership Interests for any purpose.

SECTION 5.3. Tag Along Rights.

(a) Prior to any Summit Member(s) (the “Selling Summit Member(s)”) making any Transfer of Units, the Selling Summit Member(s) shall give prior written notice to each Class B Member and the Company, which notice (the “Sale Notice”) shall (A) identify the amount of Units held by the Selling Summit Holder(s) to be Transferred (the “Offered Securities”) and the fraction, expressed as a percentage, determined by dividing the Sharing Percentage attributable to the Offered Securities by the total Sharing Percentage attributable to all Units held by the Summit Member(s) (the “Tag-Along Percentage”) and (B) describe the terms and conditions of such proposed Transfer, including the per unit price of the Units held by the Selling Summit Member(s) desired to be sold, the implied equity valuation of the Company based upon such per unit price of such Units desired to be sold and the amount that would be received in exchange for each Class B Unit as determined pursuant to Section 5.3(c).

(b) Any of the Class B Members may, within 20 days of the delivery of the Sale Notice, give written notice (each, a “Tag-Along Notice”) to the Selling Summit Member(s) that such Class B Member wishes to participate in such proposed Transfer upon the same terms and conditions as the Selling Summit Member(s) other than as set forth in this Section 5.3(b) and Section 5.3(c). Any Class B Member who does not deliver a Tag-Along Notice within such 10 day period shall be deemed to have waived all of such Class B Member’s rights with respect to the proposed sale. A Tag-Along Notice shall specify the amount of Class B Units such Class B Member desires to include in such proposed Transfer (not in any event to exceed the Tag-Along Percentage as applied to the Class B Units held by the Class B Member). To exercise its tag-along rights hereunder, each Class B Member must agree to make the same representations, warranties, covenants, indemnities and agreements as the Selling Summit Member(s) make in connection with the Transfer of the Offered Securities (except that in the case of representations and warranties pertaining specifically to, or covenants, indemnities or other agreements made specifically by, the Selling Summit Member(s), each such Class B Member shall make, to the extent applicable, comparable representations and warranties pertaining specifically to (and, as applicable, covenants, indemnities or other agreements by) each such Class B Member), and must agree to bear his or its ratable share (which shall be several and shall be based on, and limited to, the gross proceeds received by each such Class B Member) of all liabilities arising out of representations, warranties, covenants, indemnities or other agreements (other than those representations, warranties, covenants, indemnities or other agreements that pertain specifically to a given Class B Member, who shall bear all of the liability related thereto) made in connection with the Transfer.

(c) The offer of each Class B Member contained in such Class B Member’s Tag-Along Notice shall be irrevocable and, to the extent such offer is accepted by the transferee, such Class B Member shall be obligated to Transfer Class B Units in the proposed sale by the Selling Summit Member(s) at a price per Class B Unit calculated by (1) taking the per unit price of the Units held by the Selling Summit Member(s) to be sold and calculating an implied valuation of the Company based on such price, (2) calculating the valuation that all Class B Members would receive in respect of their Class B Units in a hypothetical sale of the entire Company where proceeds equal to such implied valuation described in clause (1) immediately above were received in such hypothetical sale and were distributed to the Members pursuant to Section 4.4(a)(ii), and (3) calculating the per unit price of one Class B Unit based on the

aggregate proceeds to be received by the Class B Members in respect of all Class B Units in the hypothetical sale described in clause (2) immediately above and dividing such amount by the number of outstanding Class B Units. Subject to the foregoing sentence and the last sentence of Section 5.3(b) above, the Transfer of Class B Units shall otherwise be on the same terms and conditions as the Selling Summit Member(s) Transfer Units, up to such number of Class B Units as such Class B Member shall have specified in its Tag-Along Notice; provided, however, that if the material terms of the proposed sale change with the result that the per unit price for a Class B Unit shall be less than the per unit price set forth in the Sale Notice, the form of consideration shall be different or the other terms and conditions shall be materially less favorable to the Class B Member than those set forth in the Sale Notice, each Class B Member that has previously delivered a Tag-Along Notice shall be permitted to withdraw the offer contained in such holder’s Tag-Along Notice by written notice to the Selling Summit Member(s) and upon such withdrawal shall be released from such holder’s obligations, and the Selling Summit Member(s) shall either cancel such Transfer of Units or send a new Sale Notice setting forth the revised terms and conditions of such sale.

(d) Each Member participating in any such sale will bear (x) its or his own costs of any sale of Units pursuant to this Section 5.3 and (y) its or his pro-rata share (based upon the relative amount of proceeds received for the Units sold) of the costs of any sale of Units pursuant to this Section 5.3 to the extent such costs are incurred for the benefit of all participating Members and are not otherwise paid by the Company or the transferee. Costs incurred by or on behalf of a Member for its or his sole benefit will not be considered costs of the transaction hereunder.

(e) Nothing in this Agreement shall limit any rights a Member has with respect to any agreement validly entered into with the Company or one of its Subsidiaries with respect to any advisory or similar fees.

(f) If none of the Class B Members gives the Selling Summit Member(s) a timely Tag-Along Notice with respect to the Transfer proposed in the Sale Notice, then the Selling Summit Member(s) may Transfer such Offered Securities at a per unit price no greater than the price set forth in the Sale Notice and on other terms and conditions not materially more favorable to the Selling Summit Member(s) than those set forth in the Sale Notice at any time within 120 days (subject to extension to the extent necessary to obtain required governmental or other approvals) after expiration of the 10-day period for giving Tag-Along Notices with respect to such Transfer. Any such Offered Securities not Transferred by the Selling Summit Member(s) during such period will again be subject to the provisions of this Section 5.3 upon a proposed subsequent Transfer. If one or more Class B Members give the Selling Summit Member(s) a timely Tag-Along Notice, then the Selling Summit Member(s) shall use their reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of the Class B Members in any contemplated Transfer, on the same terms and conditions as are applicable to the Offered Securities, except as otherwise provided in Sections 5.3(b) and 5.3(c) above. If the prospective transferee(s) is unwilling or unable to acquire all of the Offered Securities specified in a timely Tag-Along Notice upon such terms, then the Selling Summit Member(s) shall elect either to cancel such proposed Transfer or to reduce the number of Class A Units and Class B Units on a proportionate basis to a number that the prospective transferee(s) are willing to purchase.

(g) Notwithstanding anything contained in this Section 5.3 to the contrary, there shall be no liability or obligation on behalf of any Summit Member or the Company if the Selling Summit Member(s) determine, for any reason, not to consummate a Transfer referred to in this Section 5.3.

(h) Excluded Transfers. The rights and restrictions contained in Sections 5.3(a) through (g) shall not apply with respect to any of the following Transfers of Units:

(i) any Transfer of Units to any Permitted Transferee of a Summit Member;

(ii) any Transfer by the equityholders of Summit Holdco of their equity interests in Summit Holdco;

(iii) any Transfer of Units held by a Summit Member to and among the members or partners of the Summit Member(s) and the members, partners and employees of such members and partners;

(iv) any Transfer of Units in accordance with Section 5.4; and

(v) any Transfer of Units held by a Summit Member to employees or directors of, or consultants to, any of the Company or its Subsidiaries.

SECTION 5.4. Drag-Along Rights.

(a) If at any time following the fifth anniversary of the Closing Date, subject to the limitations and conditions set forth in this Section 5.4, (x) the Summit Member(s) elect to consummate, or to cause the Company to consummate, a sale of all of the assets or all of the equity interests in the Company by whatever means (including merger, consolidation, equity purchase, sale of assets or otherwise) or (y) the equityholders of Summit Holdco elect to consummate a Sale of Control of Summit Holdco (or any Subsidiary of Summit Holdco holding, directly or indirectly, Summit Holdco’s equity interest in the Company), to the extent the Summit Member(s) or the equityholders of Summit Holdco, as applicable, choose to notify the Company and the other Members in writing of that election, the other Members and the Board will consent to and raise no objections to the proposed transaction, and the other Members, the Board and the Company will take all other actions reasonably necessary or desirable to cause the consummation of such transaction on the terms proposed by the Summit Member(s) or the equityholders of Summit Holdco, as applicable (a “Drag Along Sale”). Without limiting the foregoing and subject to the limitations and conditions set forth in this Section 5.4, (i) if the proposed Drag Along Sale requires approval of the Members, the Members will vote or cause to be voted all Units that they hold or with respect to which the Members have the power to direct the voting and which are entitled to vote on such transaction in favor of such transaction and will waive any statutory appraisal rights which the Members may have in connection therewith, and

(ii) if the proposed Drag Along Sale is structured as or involves a sale or redemption of Units or other equity interests, each Member other than the Summit Member(s) will agree to sell all of the Units held by such Member. The Members will execute any merger, asset purchase, security purchase, recapitalization or other sale agreement approved by the Summit Member(s) or the equityholders of Summit Holdco, as applicable, in connection with such Drag Along Sale provided that in the event that (x) the Class B Members will not be entitled to proceeds in the Drag Along Sale (with respect to Class B Units, calculated pursuant to clause (iv) of Section 5.4(b)), (A) the Class B Members shall not be required to make any representations, warranties, covenants, indemnities or agreements other than customary representations and warranties as to due organization, authority to enter into the applicable transaction agreement, enforceability, non-contravention and title to the Units held by such Class B Member, and (B) each Class B Member shall not be liable for any representations, warranties, covenants, indemnities or other agreements other than those representations and warranties that pertain specifically to such Member, or (y) in the event that clause (x) immediately above does not apply, the Class B Members shall be required to make the same representations, warranties, covenants, indemnities and agreements that the Summit Member(s) make in the applicable transaction agreement, including, if applicable, agreeing to bear, his, her or its ratable share (which may be joint and several but shall be based on, and limited to, the gross proceeds to be received by each such Member from the Drag Along Sale, which limit shall be reduced on a proportionate basis to the extent the liability of the Company or the selling Members has been limited to an amount less than gross proceeds in such Drag Along Sale) of all liabilities arising out of representations, warranties, covenants, indemnities or other agreements (other than those representations, warranties, covenants, indemnities or other agreements that pertain specifically to a given Member (or group of Members) other than such Member, with such given Member (or group of Members) to bear all of the liabilities related thereto) made in connection with the Drag Along Sale (except that (i) in the case of representations and warranties pertaining specifically to the Summit Member(s) or another Member, each Member shall make the comparable representations and warranties pertaining specifically to itself, (ii) in the case of covenants or agreements capable of performance only by certain Members, such covenants or agreements shall be made only by such certain Members and (iii) in the case of a Sale of Control of Summit Holdco (or any Subsidiary of Summit Holdco holding, directly or indirectly, Summit Holdco’s equity interest in the Company), the other Members shall not be required to make any representations or warranties relating to Summit Holdco or any of its Subsidiaries other than the Company and its Subsidiaries). In the event that, due to the joint and several obligation of a Member to satisfy the aforementioned liabilities in such Drag Along Sale, the purchaser or its related party in such Drag Along Sale seeks a payment from such Member in excess of such Member’s pro-rata portion of the gross proceeds in such Drag-Along Sale (which pro-rata portion shall be based upon the gross proceeds received by such Member in the Drag Along Sale, as compared to the gross proceeds received by all Members in the Drag Along Sale), then each of the other Members participating in such sale shall contribute to such Member an amount up to the contributing Member’s pro-rata portion of the gross proceeds in such Drag Along Sale sufficient to give effect to the limitation on liability as provided in this Section 5.4(a) and in any instance, subject to the limits as provided in the foregoing sentence, with any such limit to be applied to each Member in accordance with this pro-rata portion of the gross proceeds.

(b) The obligations of the Members other than the Summit Member(s) with respect to the Drag Along Sale are subject to the satisfaction of the following conditions: (i) in connection with any Drag Along Sale of the Company not involving Summit Holdco or any of its Subsidiaries other than the Company and its Subsidiaries requiring participation by the Company or any Members other than the Summit Member(s), the Company shall be required to engage an independent investment banking firm selected by the Board, which investment banking firm shall manage a sale process designed to maximize the price taking into account certainty and other non-financial terms and conditions of such Drag Along Sale and otherwise assist the Company and its Members with such Drag Along Sale; (ii) in connection with any Drag Along Sale in which an independent investment banking firm is required to be hired pursuant to clause (i) immediately above, the receipt by the Company and the Board of a fairness opinion of such independent investment bank as to the fairness, from a financial point of view, of the consideration to be received by the Class B Members in respect of their Class B Units in the Drag Along Sale; (iii) all of the Members shall receive the same form of consideration, or if any Members are given an option as to the form and amount of consideration to be received, all Members will be given the same option; and (iv) the consideration to be received by Class B Members in respect of their Class B Units (A) in a Drag Along Sale of the Company not involving Summit Holdco or any of its Subsidiaries other than the Company and its Subsidiaries will be at a price per Class B Unit calculated by taking the aggregate proceeds from such Drag Along Sale and allocating such proceeds based upon a hypothetical distribution of such proceeds by the Company pursuant to Section 4.4(a)(ii), and (B) in a Drag Along Sale of the Company involving Summit Holdco or its Subsidiaries in addition to the Company and its Subsidiaries will be at a price per Class B Unit determined through the valuation methodology set forth in Section 5.6(d)(ii)(A) as if such Class B Units were purchased through the exercise of the Put Right for cash pursuant to such Section.

(c) Each Member will bear (x) its or his own costs of any sale of Units pursuant to a Drag Along Sale and (y) its or his pro-rata share (based upon the relative amount of proceeds received for the Units and other equity interests sold) of the costs of any sale of Units or other equity interests pursuant to a Drag Along Sale to the extent such costs are incurred for the benefit of all participating Members (or selling equityholders in any Drag Along Sale involving Summit Holdco or its Subsidiaries in addition to the Company and its Subsidiaries) and are not otherwise paid by the Company, Summit Holdco or the transferee (provided that Section 10.2 to apply to such Drag Along Sale unless otherwise agreed by the Summit Member(s)). Costs incurred by or on behalf of a Member for its or his sole benefit will not be considered costs of the transaction hereunder. In the event that any transaction that the Summit Member(s) or the equityholders of Summit Holdco, as applicable, elect to consummate or cause to be consummated pursuant to this Section 5.4 is not consummated for any reason, the Company will reimburse the Summit Member(s) or the equityholders of Summit Holdco, as applicable, for all actual and reasonable expenses paid or incurred by the Summit Member(s) or the equityholders of Summit Holdco, as applicable, for the benefit of the Company and/or all of its Members in connection therewith (in the case of a Drag Along Sale involving Summit Holdco or its Subsidiaries in addition to the Company and its Subsidiaries, based upon a reasonable allocation of expense as between Summit Holdco and the Company as agreed between the Board (subject to Section 3.3(a)(iv)) and Summit Holdco).

(d) Nothing in this Agreement shall limit any rights a Member has with respect to any agreement validly entered into with the Company or one of its Subsidiaries with respect to any advisory or similar fees.

(e) Notwithstanding anything contained in this Section 5.4 to the contrary, there shall be no liability or obligation on behalf of any Summit Member, any equityholder of Summit Holdco, their respective Affiliates or the Company if the Summit Member(s) or equityholders of Summit Holdco, as applicable, determine, for any reason, not to consummate a Drag Along Sale, and the Summit Member(s) or equityholders of Summit Holdco, as applicable, shall be permitted to, and shall have the authority to cause the Company to, discontinue at any time any Drag Along Sale initiated by the Summit Member(s) or equityholders of Summit Holdco, as applicable, by providing written notice to the Company.

SECTION 5.5. Rollover Exchange.

(a) To the extent that the equityholders of Summit Holdco or the board of directors or similar governing body thereof resolve or otherwise determine to undertake a Summit IPO (and so long as Summit Holdco, through the Summit Member(s), continues to Control the Company at such time), then, following the engagement of any lead underwriting bank(s) in connection therewith, the Summit Member(s) shall cause such lead underwriting bank(s) (the “Underwriters”) to, as part of their valuation analysis of Summit Holdco and its subsidiaries, undertake to complete a valuation of the Company and of the Class B Members’ interest in the Company relative to the value of Summit Holdco and its subsidiaries on a consolidated basis (assuming for such purposes 100% ownership of the Company by the Summit Member(s)), in each case, based upon the valuation methodology set forth in Schedule III to this Agreement, which valuation shall be final and binding on the parties for purposes of this Section 5.5. The Summit Member(s) shall cause such valuation to be reduced to writing (the “IPO Valuation Notice”) and delivered to each of the Class B Members promptly following the completion of such valuation and, to the extent reasonably practicable, no later than 15 days prior to the filing of the initial registration statement under the Securities Act relating to the Summit IPO.

(b) If Summit Holdco, through the Summit Member(s), continues to Control the Company at such time, each Class B Member shall have the right, but not the obligation (subject to the requirements of Section 5.6 to the extent applicable), exercisable within fifteen days after receipt of the IPO Valuation Notice by delivering written notice thereof to the Company and to the Summit Member(s), to exchange or otherwise transfer in a manner determined by the Summit Member(s) in their discretion, subject to and contingent upon consummation of the Summit IPO, all, but not less than all, of the Class B Units held by such Class B Member for common equity of Summit Holdco (“Summit Holdco Common Shares”) pursuant to the terms and conditions of this Section 5.5 (the “Rollover Exchange”). Any written notice by a Class B Member to participate in a Rollover Exchange shall be irrevocable, and to the extent that a Class B Member fails to timely deliver or otherwise does not deliver a written notice electing to participate in the Rollover Exchange within the time period required above such Member shall be deemed to have irrevocably waived its, his or her right to participate in the Rollover Exchange absent a written agreement otherwise by the Summit Member(s) (but any such waiver shall not otherwise affect the rights a Class B Member may have pursuant to Section 5.6).

(i) Each participating Class B Member shall receive in respect of their Class B Units, substantially concurrent with the consummation of the Summit IPO, a number of Summit Holdco Common Shares (rounded to the nearest share) calculated based on the following:

S = (IRP * MP) * CS

(1- (IRP * MP))

where:

S = the number of Summit Holdco Common Shares to be issued to such participating Member

IRP = the Class B Indirect Rollover Percentage (as defined in Schedule III hereto) attributable to all Class B Members

MP = a fraction, the numerator of which is the number of Class B Units held by such participating Member and the denominator of which is the number of Class B Units held by all Class B Members including such participating Member

CS = the number of Summit Holdco Common Shares outstanding or to be outstanding immediately prior to the consummation of the Rollover Exchange but disregarding for such purposes (1) any issuance of shares by Summit Holdco occurring in connection with the Summit IPO, (2) any Summit Holdco Common Shares issued in respect of, or underlying, equity incentive or similar awards (including upon any conversion or reorganization of Summit Holdco undertaken in connection with the Summit IPO) to directors, officers, employees, consultants or agents of Summit Holdco or any of its Subsidiaries pursuant to a plan or arrangement established by the board of directors or similar managing body of Summit Holdco or its predecessors or by the equityholders of Summit Holdco, and (3) any Summit Holdco Common Shares, if any, underlying warrants, options or other securities exercisable for such Summit Holdco Common Shares and held by Persons other than Summit Holdco, its Subsidiaries, Blackstone and the other equityholders of Summit Holdco existing as of the date of this Agreement

(ii) The Members participating in the Rollover Exchange shall receive customary registration rights with respect to the Summit Holdco Common Shares received in respect of the Rollover Exchange based upon a registration rights

agreement to be negotiated in good faith between Summit Holdco and such participating Members concurrently with the Rollover Exchange, which registration rights agreement will include the following terms (in the case of clause (A), to the extent applicable):

(A) in the event that all (but not less than all) of the Class B Members elect to participate in the Rollover Exchange in connection with the Summit IPO, such Class B Members holding a majority of the Summit Holdco Common Shares received in connection with the Rollover Exchange shall be entitled to one customary “demand” registration right covering the Summit Holdco Common Shares received by the Class B Members participating in the Rollover Exchange, provided that the market value of such shares is at least $40 million, which right shall be exercisable at any time from and after the third anniversary of the Summit IPO; and

(B) each Member participating in the Rollover Exchange shall receive customary “piggyback” registration rights on any underwritten registered offering following the Summit IPO in which Blackstone participates.

No Member participating in the Rollover Exchange shall be entitled to participate and sell Summit Holdco Common Shares in the Summit IPO without the prior written consent of Blackstone.

(iii) Each participating Member shall, and hereby agrees to, provide such representations, warranties and covenants as would be customary in such a transaction of this nature, including the following:

(A) representations and warranties as to ownership and title to the Units held by such Member, including that it is the sole beneficial and record owner of such Class B Units with the full right, power and authority to convey such Class B Units to Summit Holdco, free and clear of all liens and encumbrances;

(B) representations and warranties customarily required in order to establish that the Rollover Exchange satisfies the requirements necessary in order for the issuance of the Summit Holdco Common Shares in connection with the Rollover Exchange to be exempt from registration under the Securities Act;

(C) agreeing to, in connection with any underwritten offering of Summit Holdco Common Shares, including the Summit IPO, abide by any underwriter’s lockup restrictions requested of them by the underwriters in such underwritten offering and any lockup restrictions imposed on Blackstone;

(D) providing to the Company, Summit Holdco, and any underwriters in an underwritten public offering such information regarding itself or its ownership of Units or Summit Holdco equity as is requested by any of them to be included in a registration statement relating to the equity securities of Summit Holdco; and

(E) providing the Company, Summit Holdco, any underwriter and any of their officers, directors, affiliates or controlling persons customary indemnification protection in connection with representations and warranties made, or information otherwise provided for use in a registration statement by such Member in connection with the Summit IPO or any subsequent underwritten offering in which such Member participates.

(iv) Without limiting the requirements of Section 5.5(c)(iii), each participating Member shall, and hereby agrees to, promptly take such actions and execute, deliver and perform any and all agreements and other documentation as are necessary or reasonably requested by the Company, Summit Holdco or its equityholders in collection with the Rollover Exchange and Summit IPO, including to effect any of the provisions in this Section 5.5.

(v) Each participating Member shall bear its, his or her own costs and expenses of participating in the Rollover Exchange, including any and all transfer taxes arising from the exchange of the Class B Units for Summit Holdco Common Shares.

SECTION 5.6. Put/Call of Class B Units.

(a) Subject to the terms and conditions set forth in this Section 5.6, the Summit Member(s) shall have the right (but not the obligation) to require the Company to purchase all (but not less than all) of the Class B Units held by Class B Members (the “Call Right”) at any time after the sixth anniversary of the Closing Date either (x) in anticipation of the Summit IPO (but concurrently with and contingent upon completion of the Summit IPO) or (y) if the Summit IPO has already occurred. Notwithstanding the foregoing, in the event of a Sale of Control of Summit Holdco occurring prior to the fifth anniversary of the Closing Date, the Summit Member(s), or the Person succeeding to the interest of the Summit Member(s), following such Sale of Control shall not be entitled to exercise the Call Right for any reason prior to the later of the sixth anniversary of the Closing Date and the third anniversary of the date of consummation of the Sale of Control of Summit Holdco. To exercise the Call Right, the Summit Member(s) shall deliver to the Company, which in turn shall deliver to the Rollover Members, a written notice that the Summit Member(s) have elected to exercise the Call Right.

(b) Subject to the terms and conditions set forth in this Section 5.6, each Class B Member shall have the right (but not the obligation) to require the Company to purchase all (but not less than all) of the Class B Units held by such Class B Member and its Permitted Transferee(s) holding Class B Units (the “Put Right”) (i) in connection with a Sale of Control of Summit Holdco occurring after the Second Lien Date and prior to the sixth anniversary of the Closing Date (but subject to and contingent upon the consummation of such Sale of Control); or (ii) at any time following the sixth anniversary of the Closing Date (whether or not a Sale of Control has previously occurred). The Summit Member(s) shall, prior to any anticipated Sale of

Control of Summit Holdco occurring prior to the fifth anniversary of the Closing Date, provide written notice thereof. To exercise its Put Right, a Class B Member shall deliver to the Company a written notice informing the Company that such Class B Member has elected to exercise its Put Right and, in the case where such Class B Member has the option to choose between cash and stock consideration pursuant to Section 5.6(c) below, stating whether it elects to receive cash or stock consideration; provided that in the case of an anticipated Sale of Control of Summit Holdco occurring prior to the fifth anniversary of the Closing Date, such written notice must be delivered to the Company and the Summit Member(s) no later than 10 days following receipt by the Class B Members of the written notice from the Summit Member(s) of the anticipated Sale of Control. Any failure to provide written notice within the 10 day period set forth in the provisio in the foregoing sentence shall be deemed an irrevocable waiver of such Class B Member’s right to exercise its Put Right in connection with such Sale of Control, but shall not otherwise affect its right to exercise the Put Right following the sixth anniversary of the Closing Date. Any written notice of exercise of the Put Right by a Class B Member shall be irrevocable absent the written consent of the Summit Member(s).

(c) In connection with any exercise of the Put Right or Call Right where Summit Holdco Common Shares are then publicly-traded or in connection with the exercise of the Call Right made in anticipation of the Summit IPO (and where Summit Holdco, through the Summit Member(s), continues to Control the Company), each Class B Member shall be entitled to elect to receive for its Class B Units cash consideration or, in lieu of cash, a number of Summit Holdco Common Shares, in each case, as determined pursuant to Section 5.6(d) below.

(d) The value for each Class B Unit to be purchased pursuant to the Call Right or Put Right, as applicable, will be calculated based on the fair market value as agreed upon by the Board and the Class B Members selling Class B Units pursuant to the Call Right or Put Right, as applicable, provided that if no amount can be agreed upon within 10 days of delivery of the Call Right or Put Right notice, as applicable, or if the parties otherwise so desire, then such amount shall be determined as follows:

(i) where the exercise of the Call Right is made in anticipation of the Summit IPO and where a Class B Member elects to receive Summit Holdco Common Shares as consideration, then such Class B Member shall receive a number of Summit Holdco Common Shares calculated in the manner set forth in Section 5.5 as if such Class B Member had elected to participate in a Rollover Exchange;

(ii) in the event of exercise of the Call Right or Put Right in all scenarios provided in Sections 5.6(a) and (b) other than that described in Section 5.6(d)(i):

(A) the value of the Class B Units being purchased will be determined by an independent investment banking or other valuation firm selected jointly (and equally paid for) by the Class B Members and the Company and applying the valuation methodologies set forth on Schedule IV hereto; provided, however, if either the Class B Member(s) or the Board gives written notice to the

other within 5 days after the expiration of the foregoing 10 day period that it desires to have three investment banks determine the fair market value, or if the Class B Member(s) and the Board cannot agree on one investment bank within such 10 day period, the fair market value shall be determined by three investment banks each applying the valuation methodologies set forth on Schedule IV hereto, one selected and paid by the participating Class B Member(s), one selected by the Board (both within 10 days after the expiration of the foregoing 10 day period), and the third selected by the other two within 10 days of the foregoing 10 day period (and paid equally by the participating Class B Member(s) and the Company). If one investment bank or valuation firm is selected, then its determination is the fair market value. If three investment banks are selected, the fair market value shall be the average of the two closest determinations in dollar value made by the three. Such determination shall be final and binding on all parties. To the extent one or more investment banks or valuation firms are engaged as provided above, the purchase price shall be determined within 30 days of appointment of the independent valuation firm or investment bank(s). Notwithstanding the foregoing, in the event of exercise of a Put Right where a valuation by one or more independent investment banking or other valuation firms in a valuation process conducted pursuant to this Section 5.6 has occurred in the nine months prior to the date on which the written notice of exercise of such Put Right is delivered, then the value of the Class B Units being purchased will be based upon such prior valuation unless the Company elects, in its discretion as determined by the Board, to require a new valuation in accordance with the principles set forth above to be undertaken; and

(B) to the extent that a Class B Member has elected to receive Summit Holdco Common Shares as consideration for its Class B Units where the valuation of such Class B Units has been determined pursuant to this Section 5.6(d)(ii), then such Class B Member shall receive a number of Summit Holdco Common Shares equal to the value of such Class B Member’s Class B Units as determined pursuant to Section 5.6(d)(ii)(A) above divided by the volume weighted average trading price of the Summit Holdco Common Shares as reported by Bloomberg L.P. (based on composite trading) for the 10 trading days ending on the trading day immediately prior to the date of the Put Right or Call Right, as applicable, exercise notice.

(e) Each Class B Member shall, and hereby agrees to, promptly take such actions and execute, deliver and perform any and all agreements and other documentation as are necessary or reasonably requested by the Company and/or Summit Holdco in connection with the exercise of the Put Right or Call Right. Without limiting the foregoing, each Class B Member shall, and hereby agrees to, provide representations, warranties and covenants as would be customary in a transaction of the nature contemplated in this Section 5.6, which representations and warranties shall be limited to customary representations and warranties as to due organization, authority to enter into the applicable documentation, enforceability, non-contravention, title to the Units held by such Class B Member and representations and warranties

customarily required in order to establish that any exchange of Class B Units satisfies the requirements necessary in order for the issuance of Summit Holdco Common Shares in connection with such exchange to be exempt from registration under the Securities Act.

(f) In the event that the Summit Member(s) exercise the Call Right or where none of the Class B Members elect to participate in the Rollover Exchange but all Class B Members subsequently elect at the same time to exercise their Put Right and, in either such case, all such Class B Members elect to receive Summit Holdco Common Shares as consideration, then the Class B Members shall collectively be entitled to one “demand” registration right on the same terms and conditions as set forth under Section 5.5(c)(ii). Any Class B Members receiving Summit Holdco Common Shares as consideration for their Class B Units in connection with the exercise of the Call Right or Put Right shall also be entitled to “piggyback” registration rights on the same terms and conditions as described under Section 5.5(c)(ii).

(g) Subject to Section 5.6(h), the closing of the purchase of the Class B Units pursuant to this Section 5.6 shall occur on a date designated by the Board, and in any event within forty-five (45) days of the date on which the purchase price/value for the Class B Units is determined (unless the purchase is subject to and contingent upon the occurrence of another event (e.g., the Summit IPO), in which case, the 45 day requirement shall not apply) (such date, with respect to the Call Right, the “Call Closing Date”, and with respect to the Put Right, the “Put Closing Date”); provided that if such purchase is subject to any prior regulatory approval, then such 45-day period shall be extended until the expiration of ten business days after all such approvals shall have been received and the Company shall use its commercially reasonable efforts to obtain any such regulatory approvals as promptly as possible. Without limiting the generality of Section 5.5(e), on or prior to the Call Closing Date or Put Closing Date, as applicable, the Class B Members subject to the Put Right or Call Right, as applicable, shall execute applicable transfer instruments representing their Class B Units, duly endorsed for transfer and accompanied by all requisite transfer taxes, if any, and such Class B Units shall be free and clear of any liens, and each Class B Member subject to the Put Right or Call Right, as applicable, shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and record owner of such Class B Units with the full right, power and authority to convey such Class B Units to the Company or to Summit Holdco (if so directed by the Company). Where a Class B Member is to receive cash consideration in respect of its Class B Units, such Class B Units may be purchased by delivery of funds deposited into an account designated by such Member, a bank cashier’s check, a certified check or a company check of the Company for the purchase price.

(c) If any of the provisions of this Section 6.1 shall otherwise contravene or be invalid under the laws of any state or other jurisdiction where it is applicable but for such contravention or invalidity, such contravention or invalidity shall not invalidate all of the provisions of this Section 6.1, but rather this Section 6.1 shall be reformed and construed, insofar as the laws of that state or jurisdiction are concerned, as not containing the provision or provisions, but only to the extent that they are contravening or are invalid under the laws of that state or jurisdiction, and the rights and obligations created hereby shall be reformed and construed and enforced accordingly.

SCHEDULE III

ROLLOVER EXCHANGE VALUATION METHODOLOGY

The following principles shall apply to any determination of the value of the Company and of the interest of the Class B Members in the Company relative to the value of Summit Holdco and its subsidiaries on a consolidated basis (assuming for such purposes 100% ownership of the Company by the Summit Member(s)) in connection with a Rollover Exchange to be made pursuant to Section 5.5 of the Agreement:

The Underwriters shall (with the assistance of Summit Holdco’s accountants, to the extent so requested, but in any event based on the financial statements and books and records of Summit Holdco) calculate LTM EBITDA for the Company on a standalone basis and for Summit Holdco and its subsidiaries on a consolidated basis (assuming 100% ownership of the Company for such purposes).

The Underwriters shall determine the implied value for Summit Holdco and its subsidiaries on a consolidated basis (assuming 100% ownership of the Company for such purposes), by multiplying the LTM EBITDA for Summit Holdco as determined pursuant to Step 1 above by a multiple selected by the Underwriters based upon the Underwriters’ good faith determination as to the anticipated value of Summit Holdco on a consolidated basis at the time of and after giving effect to the Summit IPO. In the event that the Underwriters select a range of multiples, the multiple to be used for purposes of this Step 2 shall be the mid-point of such range.

The implied value of the Company on a standalone basis shall be determined by multiplying the LTM EBITDA for the Company as determined pursuant to Step 1 above by the same multiple used in Step 2 with respect to Summit Holdco.

The relative value of the Company within the overall Summit Holdco structure (the “Company Percentage”) shall be determined by dividing the value of the Company on a standalone basis by the value of Summit Holdco on a consolidated basis (assuming 100% ownership of the Company for such purposes), in each case, as determined based on the Steps above.

The percentage interest of the Class B Members in the value of the Company (the “Class B Percentage”) shall be determined based upon the percentage of the overall distribution amount that the Class B Members would be entitled to receive if an amount equal to the value of the Company determined based upon the methodology above were distributed to the Members pursuant to Section 4.4(a)(ii) of the Agreement.

The Company Percentage will then be multiplied by the Class B Percentage (in each case, expressed as a decimal to eight decimal places) to establish the “Class B Indirect Rollover Percentage” (to be expressed as a decimal to eight decimal places).

As a clarification, the determinations hereunder shall not take into account a non-control discount, illiquidity discount or similar factors that would not be incorporated in valuing the entire equity value of the Company.

SCHEDULE IV

PUT/CALL VALUATION METHODOLOGY

The following principles shall apply to any determination of the purchase price of the Class B Units in connection with the exercise of the Call Right or Put Right, as applicable, pursuant to Section 5.6(d)(ii) of the Agreement:

The fair market value shall be based on the equity value of the Company as a going concern;

The purchase price shall be the price of the Class B Units being sold determined by applying the fair market value determined on the basis above and based on a hypothetical liquidation and distribution of the Company to the Members in respect of their Units pursuant to Section 4.4(a)(ii) of the Agreement; and

In determining the purchase price of the Class B Units being sold, such determination shall not take into account a non-control discount, illiquidity discount or similar factors that would not be incorporated in valuing the entire equity value of the Company.
