Except as otherwise provided in this Article III, Units in a particular class may be issued from time to time, at such prices and on such terms as the Board (which issuance, prices and terms must have been approved by at least one GSCP Director and at least one Kelso Director) or, in the case of Override Units, the Override Unit Committee may determine, without obtaining the consent of any Member or class of Members.

     (c) Quorum. Except as otherwise required by applicable law or by the Certificate, the presence in person or by proxy of the holders of record of a Majority in Interest shall constitute a quorum for the transaction of business at such meeting.

If the Board has fixed a record date, every holder of record of Units entitled to vote at a meeting of Members or to consent in writing in lieu of a meeting of Members as of such date shall be entitled to one vote for each such Unit outstanding in such Member’s name at the close of business on such record date.

     (e) Proxies. Each Member may authorize any Person to act for such Member by proxy on all matters in which a Member is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting.

     (f) Organization. Each meeting of Members shall be conducted by such Person as the Board may designate.

     (g) Action Without a Meeting. Unless otherwise provided in this Agreement, any action which may be taken at any meeting of the Members may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by a Majority in Interest.

     Section 3.7 Preemptive Rights.

     (b) Prior to the issuance of Interests by the Company as to which Section 3.7(a) applies, the Company shall give written notice (the “First Company Notice”) thereof to each eligible Member, which First Company Notice shall state, for each Member, the product of (x) the number of the Proposed Third Party Interests proposed to be issued to the third party or parties giving rise to these preemptive rights and (y) such Member’s percentage ownership interest in the Company immediately prior to such notice (the product of (x) and (y), a Member’s “Pro Rata Preemptive Amount”). Each eligible Member that wishes to exercise its rights under this Section 3.7 shall deliver a written notice to that effect to the Company within 30 days after its receipt of the First Company Notice to exercise its rights on the same terms and conditions as those offered to the third-party purchaser (which Member notice shall state the portion of such Member’s Pro Rata Preemptive Amount that such Member elects to purchase pursuant hereto (such portion, the “Initial Purchase Amount”)); provided that, if a Member either (x) fails to deliver such notice to the Company within 30 days after its receipt of the First Notice or (y) notifies the Company that it elects not to purchase any or a portion of its Pro Rata Preemptive Amount, then such Member shall have rejected its right to purchase all or such portion of its Pro Rata Preemptive Amount (as such, the “Rejected Amount”) and, promptly after the expiration of such 30 day period or receipt of such notice, as the case may be, the Company shall notify the other Members hereof and of their respective pro rata share in such Rejected Amount (each such notice, a “Second Company Notice”). The other Members shall have the right to purchase all or any portion of their respective pro rata share of any Rejected Amount and any Member that wishes to exercise such right with respect to any Rejected Amount shall deliver a written notice to that effect to the Company within ten days after its receipt of the Second Company Notice in respect of such Rejected Amount (which Member notice shall state the portion of the pro rata amount of such Rejected Amount that such Member elects to purchase (any such portion, an “Additional Purchase Amount”). The Company shall issue an aggregate number of Proposed Third Party Interests to each Member that has given written notice of the exercise of its rights hereunder equal to the Initial Purchase Amount and the sum of all Additional Purchase Amounts applicable to such Member as soon as practicable, and in no event later than the later of (i) five Business Days after receipt of such notice, and (ii) the closing of the issuance of such Interests to the third-party purchaser, against payment to the Company by such Member of solely cash consideration for such Interests. Any Interests offered or proposed to be issued by the Company on different terms and conditions as those offered to the Members must be re-offered to the Members pursuant to this Section 3.7.

     Section 3.8 Other Business of Members.

     (a) Existing Business Ventures. Each Member, Director and their respective Affiliates may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Company, and the Company, the Directors and the Members shall have no rights by virtue of this Agreement in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Company, shall not be deemed wrongful or improper.

     (b) Business Opportunities. No Member, Director or any of their respective Affiliates shall be obligated to present any particular investment opportunity to the Company even if such opportunity is of a character that the Company or any of its Subsidiaries might reasonably be

deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Member, Director or any of their respective Affiliates shall have the right to take for such Person’s own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment opportunity.

     (c) Management Members. For the avoidance of doubt, the provisions of Sections 3.8(a) and (b) shall not in any way limit any non-competition or non-solicitation restrictions contained in an employment, severance, separation or services agreement between any Management Member or any other Member who is an employee of the Company or any of its Subsidiaries and the Company or any of its Subsidiaries.

ARTICLE IV

MANAGEMENT

     Section 4.1 Board.

     (a) Generally. The business and affairs of the Company shall be managed by or under the direction of a committee of the Company (the “Board”) consisting of such number of natural persons (each, a “Director”) as shall be established by mutual consent of GSCP and Kelso from time to time. Subject to any rights that may be granted pursuant to Section 3.6(b), the Directors shall be appointed to the Board upon the vote, approval or consent of a Majority in Interest with all Members agreeing to vote their Units as designated in Section 4.1(b); it being understood and agreed that by executing this Agreement each Member elects the persons listed in Section 4.1(b)(i) to serve as the initial Directors. Directors need not be Members. Subject to the other provisions of this Article IV, the Board shall have full, exclusive and complete discretion to manage and control the business and affairs of the Company, to make all decisions affecting the business and affairs of the Company and to take all such actions as it deems necessary or appropriate to accomplish the purposes of the Company as set forth herein, including, without limitation, to exercise all of the powers of the Company set forth in Section 2.2 of this Agreement. Each person named as a Director herein or subsequently appointed as a Director is hereby designated as a “manager” (within the meaning of the Delaware Act) of the Company. Except as otherwise provided herein, and notwithstanding the last sentence of Section 18-402 of the Delaware Act, no single Director may bind the Company, and the Board shall have the power to act only collectively in accordance with the provisions and in the manner specified herein. Each Director shall hold office until a successor is appointed in accordance with Section 4.1(b) or until such Director’s earlier death, resignation or removal in accordance with the provisions hereof.

     (b) Election of Directors.

     (i) Initial Directors. Subject to GSCP’s and Kelso’s right to increase or decrease the authorized number of Directors pursuant to the first sentence of Section 4.1(a), the Board shall consist of five Directors, two of which shall be GSCP Directors and two of which shall be Kelso Directors and the fifth shall be jointly designated by GSCP and Kelso. The two GSCP Directors referenced in the immediately preceding sentence shall be Scott Lebovitz and Kenneth Pontarelli, and the two Kelso Directors

referenced in the immediately preceding sentence shall be George E. Matelich and Stanley de J. Osborne. The provisions of Section 4.1(b)(ii) below shall apply mutatis mutandis to the initial Directors pursuant to this Section 4.1(b)(i).

     (ii) GSCP and Kelso Directors. GSCP and Kelso shall each have the right to designate two of the Directors for election to the Board for as long as such party continues to hold an amount of Common Units that represents both (x) at least 20% of the Common Units then held by all Members (the “Requisite Outstanding Amount”) and (y) at least 50% of the Common Units held by such party on the date hereof (the “Requisite Original Amount”). GSCP and Kelso shall each have the right to designate one of the Directors for election to the Board for so long as such party continues to hold an amount of Common Units that represents at least 5% of the Common Units then held by all Members (the “Five Percent Test”). If either or both of GSCP and Kelso ceases or cease to have the right to designate any Director pursuant to the two immediately preceding sentences, any such Directors that such party no longer has the right to designate shall instead be designated by a Majority in Interest. For so long as GSCP is entitled to designate two of the Directors for election to the Board, one of such Directors shall be designated by GSCP Onshore and one of such Directors shall be designated by GSCP Institutional. For so long as GSCP is entitled to designate one of the Directors for election to the Board, such Director shall be designated by GSCP Institutional.

Each Member shall vote all of the Units over which it exercises voting control and shall take all other necessary or desirable actions within such Member’s control (whether in such Member’s capacity as a Member, Director, member of a Board committee or officer of the member of a Board committee or Officer or otherwise, and including, without limitation, attendance at meetings in person or by proxy for purposes of obtaining a quorum, execution of written consents in lieu of meetings and approval of amendments and/or restatements of the Certificate or this Agreement), and the Company shall take all necessary and desirable actions within its control (including, without limitation, calling special Board or Member meetings and approval of amendments and/or restatements of the Certificate or this Agreement), so that the Directors designated in accordance with this Section 4.1(b)(ii) will be elected to the Board.

     (c) Observer. To the extent that, at any time, GSCP or Kelso, as the case may be, has no Director designation rights pursuant to Section 4.1(b), such party shall have (i) the right to designate an observer to attend any meetings of the Board (which right may be waived by such party in its sole discretion) and (ii) such other rights as are set forth in a letter agreement entered into as of the date hereof between the Company, on the one hand, and each of GSCP Institutional and Kelso, on the other hand, the form of which is attached as Exhibit B hereto.

     Section 4.2 Meetings of the Board. The Board shall meet from time to time to discuss the business of the Company. The Board may hold meetings either within or without the State of Delaware. Meetings of the Board may be held without notice at such time and at such place as shall from time to time be determined by the Board. The Chief Executive Officer of the Company or a majority of the Board may call a meeting of the Board on five business days’ notice to each Director, either personally, by telephone, by facsimile or by any other similarly timely means of communication, which notice requirement may be waived by the Directors.

     Section 4.3 Quorum and Acts of the Board.

     (a) Three Directors (including at least one GSCP Director and at least one Kelso Director) shall constitute a quorum for the transaction of business. Unless the number of Directors is increased or decreased pursuant to Section 4.1(a), in which case the presence of a majority of the then authorized number of Directors shall constitute a quorum. If a quorum shall not be present at any meeting of the Board, the Directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present. Any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if a majority of the members of the Board or committee (which majority must include at least one GSCP Director and at least one Kelso Director), as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board or committee.

     (b) Except as otherwise provided in this Agreement, the act of a majority of the Directors present at any meeting at which there is a quorum shall be the act of the Board. To the extent that this Agreement requires any act of the Board or committee thereof to include the approval of, or any Board or committee majority or any Board or committee quorum to include, at least one GSCP Director and at least one Kelso Director, any such requirement shall continue to apply, with respect to the GSCP Director, for as long as GSCP continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount and, with respect to the Kelso Director, for as long as Kelso continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount.

     Section 4.4 Electronic Communications. Members of the Board, or any committee designated by the Board, may participate in a meeting of the Board, or any committee, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

     Section 4.5 Committees of Directors. The Board (a) shall designate an Override Unit Committee, which shall be comprised of (x) for as long as each of GSCP and Kelso, as the case may be, has the right to designate at least one Director pursuant to Section 4.1(b), one GSCP Director and one Kelso Director and (y) thereafter, such number of persons as may be designated by the Board and (b) may, by resolution passed by a majority of Directors (which majority must include at least one GSCP Director and at least one Kelso Director), designate one or more additional committees. Such resolution shall specify the duties, quorum requirements and qualifications of the members of such additional committees, each such committee to consist of such number of Directors as the Board may fix from time to time. Notwithstanding anything to the contrary in this Section 4.5, each committee designated hereunder shall, for so long as GSCP continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount, include at least one GSCP Director and, for so long as Kelso continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount, include at least one Kelso Director. The Board may designate one or more Directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence

or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such members constitute a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board, shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the Company. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board. Each committee shall keep regular minutes of its meetings and report the same to the Board when required.

     Section 4.6 Compensation of Directors. The Board shall have the authority to fix the compensation of Directors. The Directors may be paid their expenses, if any, of attendance at such meetings of the Board and may be paid a fixed sum for attendance at each meeting of the Board or a stated salary as a Director. No such payment shall preclude any Director from serving the Company in any other capacity and receiving compensation therefor. Members of any committee of the Board may be allowed like compensation for attending committee meetings.

     Section 4.7 Resignation. Any Director may resign at any time by giving written notice to the Company. The resignation of any Director shall take effect upon receipt of such notice or at such later time as shall be specified in the notice; and, unless otherwise specified in the notice, the acceptance of the resignation by the Company, the Members or the remaining Directors shall not be necessary to make it effective. In addition, in the event that GSCP or Kelso loses its right to designate a Director or Directors pursuant to Section 4.1(b)(ii) as a result of ceasing to hold the Requisite Outstanding Amount and the Requisite Original Amount or the Five Percent Test, as the case may be, such Director or Directors shall be deemed to have resigned from the Board effective immediately upon the occurrence of such event (it being understood and agreed that if such event only results in the loss of GSCP’s or Kelso’s right to designate one Director and such party retains the right to designate another Director pursuant to such Section 4.1(b)(ii), then such party shall designate the identity of the Director deemed to have resigned pursuant to this Section 4.7 and the identity of the Director who will remain to serve on the Board). Upon the effectiveness of any such resignation, such Director shall cease to be a “manager” (within the meaning of the Delaware Act).

     Section 4.8 Removal of Directors. Members shall have the right to remove any Director at any time for cause upon the affirmative vote of a Majority in Interest. In addition, a majority of the Directors then in office shall have the right to remove a Director for cause.

Unless otherwise decided by a majority of the Board (which majority must include at least one GSCP Director and at least one Kelso Director), each Management Member shall be an officer of the Company. Unless the Board decides otherwise, if the title is one commonly used for officers of a business corporation formed under the Delaware General Corporation Law, the assignment of such title shall constitute the delegation to such person of the authorities and duties that are normally associated with that office. Any delegation pursuant to this Section 4.11 may be revoked at any time by the Board. Any Officer may be removed with or without cause by the Board, except as otherwise provided in any services or employment agreement between such Officer and the Company.

ALLOCATIONS

     (a) Except as provided in Section 8.2, Net Income and Net Loss of the Company shall be allocated among the Members’ Capital Accounts as of the end of each Accounting Period or portion thereof in a manner that as closely as possible gives effect to the economic provisions of this Agreement.

     (b) Except as otherwise provided in Section 8.2, all items of gross income, gain, loss and deduction included in the computation of Net Income and Net Loss shall be allocated in the same proportion as are Net Income and Net Loss.

     Section 8.2 Special Book Allocations.

     (a) Qualified Income Offset. If any Member unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulations section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) and such adjustment, allocation or distribution causes or increases a deficit in such Member’s Capital Account in excess of its obligation to make additional Capital Contributions (a “Deficit”), items of gross income and gain for such Accounting Period and each subsequent Accounting Period shall be specifically allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Deficit of such Member as quickly as possible; provided that an allocation pursuant to this Section 8.2(a) shall be made only if and to the extent that such Member would have a Deficit after all other allocations provided for in this Article VIII have been tentatively made as if this Section 8.2(a) were not in this Agreement. This Section 8.2(a) is intended to comply with the qualified income offset provision of Treasury Regulations section 1.704-1(b)(2)(ii)(d) and shall be interpreted in a manner consistent therewith.

     (b) Notwithstanding anything to the contrary in this Agreement, items of gross income, gain, loss or deduction shall be specifically allocated to particular Members to the extent necessary to comply with applicable law (including the requirement to make “forfeiture allocations” within the meaning of Prop. Treas. Reg. Section 1.704-1(b)(4)(xii)).

     (c) Restorative Allocations. Any special allocations of items of income or gain pursuant to this Section 8.2 shall be taken into account in computing subsequent allocations pursuant to this Agreement so that the net amount for any item so allocated and all other items allocated to each Member pursuant to this Agreement shall be equal, to the extent possible, to the net amount that would have been allocated to each Member pursuant to the provisions of this Agreement if such special allocations had not occurred.

     Section 8.3 Tax Allocations. The income, gains, losses, credits and deductions recognized by the Company shall be allocated among the Members, for U.S. federal, state and local income tax purposes, to the extent permitted under the Code and the Treasury Regulations, in the same manner that each such item is allocated to the Members’ Capital Accounts. Notwithstanding the foregoing, the Board shall have the power to make such allocations for U.S. federal, state and local income tax purposes so long as such allocations have substantial economic effect, or are otherwise in accordance with the Members’ Interests, in each case within the meaning of the Code and the Treasury Regulations. Notwithstanding the previous sentence, in allocating income, gain, loss, credits, and deductions among the Members for U.S. federal, state, and local income tax purposes, the Board has discretion to compute Current Value by assuming that the price per Common Unit will equal the quotient obtained by dividing: (x) the aggregate capital accounts of all Members, by (y) the number of Common Units outstanding, including all Override Units issued and outstanding at the end of the taxable year, other than Override Units that, by their terms would be forfeited in conjunction with the occurrence of an Exit Event if they did not become eligible to participate in distributions pursuant to Section 7.1(a) upon the occurrence of the Exit Event. In accordance with section 704(c) of the Code and the Treasury Regulations thereunder, income, gain, loss and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company for U.S. federal income tax purposes and its Book Value.

ARTICLE IX

DISTRIBUTIONS

     Section 9.1 Distributions Generally.

     (a) The Company may make distributions to the Members to the extent that the cash available to the Company is in excess of the reasonably anticipated needs of the business (including reserves). In determining the amount distributable to each Member, the provisions of this Section 9.1 shall be applied in an iterative manner.

     (b) Subject to Sections 9.1(c) and (d), any such distributions shall be made to the Members in proportion to the number of Units held by each Member as of the time of such distribution.

     (c) The amount of any proposed distribution to a holder of any Override Unit pursuant to Section 9.1(b) in respect of such Override Unit shall be reduced until the total reductions in proposed distributions pursuant to this Section 9.1(c) in respect of such Override Unit equals the Benchmark Amount in respect of such Override Unit. Any amount that is not distributed to the holder of any Override Unit pursuant to this Section 9.1(c) shall be distributed pursuant to Section 9.1(b) and shall remain subject to this Section 9.1(c).

     (d) In the event that pursuant to Section 7.1(a) an Override Unit was not previously entitled to participate in an actual distribution made by the Company under Section 9.1(b) but under the terms of Section 7.1(a) such Override Unit is currently entitled to participate in distributions, then Section 9.1(b) notwithstanding, any distributions by the Company shall be

made 100% to the holder of such Override Unit in respect of such Override Unit until the total distributions made pursuant to this Section 9.1(d) in respect of such Override Unit equal the total distributions that would have been made in respect of such Override Unit if such Override Unit (and any other Override Units currently entitled to participate in distributions) had at all times been entitled to participate in distributions to the extent set forth in Section 7.1(a). In the event that this Section 9.1(d) applies to two or more Override Units at the same time, the distributions contemplated by this Section 9.1(d) shall be made in respect of each such Override Unit in proportion to the amounts distributable under this Section 9.1(d) in respect of each such Override Unit. For the avoidance of doubt, this Section 9.1(d) shall not apply to any Override Unit that is forfeited. The Board shall have the power in its sole discretion to make adjustments to the operation of this Section 9.1(d) if the Board determines in its sole discretion that such adjustments will further the intent of this Section 9.1(d).

     Section 9.2 Distributions In Kind. In the event of a distribution of Company property, such property shall for all purposes of this Agreement be deemed to have been sold at its Fair Market Value and the proceeds of such sale shall be deemed to have been distributed to the Members.

     (a) Each Member shall, to the fullest extent permitted by applicable law, indemnify and hold harmless each Person who is or who is deemed to be the responsible withholding agent for U.S. federal, state or local income tax purposes against all claims, liabilities and expenses of whatever nature (other than any claims, liabilities and expenses in the nature of penalties and accrued interest thereon that result from such Person’s fraud, willful misfeasance, bad faith or gross negligence) relating to such Person’s obligation to withhold and to pay over, or otherwise pay, any withholding or other taxes payable by the Company or as a result of such Member’s participation in the Company.

     (b) Notwithstanding any other provision of this Article IX, (i) each Member hereby authorizes the Company to withhold and to pay over, or otherwise pay, any withholding or other taxes payable by the Company or any of its Affiliates with respect to such Member or as a result of such Member’s participation in the Company and (ii) if and to the extent that the Company shall be required to withhold or pay any such taxes (including any amounts withheld from amounts payable to the Company to the extent attributable, in the judgment of the Members, to such Member’s Interest), such Member shall be deemed for all purposes of this Agreement to have received a payment from the Company as of the time such withholding or tax is required to be paid, which payment shall be deemed to be a distribution with respect to such Member’s Interest to the extent that the Member (or any successor to such Member’s Interest) is then entitled to receive a distribution. To the extent that the aggregate of such payments to a Member for any period exceeds the distributions to which such Member is entitled for such period, such Member shall make a prompt payment to the Company of such amount. It is the intention of the Members that no amounts will be includible as compensation income to any Management

Member, or will give rise to any withholding taxes imposed on compensation income, for United States federal income tax purposes as a result of the receipt, vesting or disposition of, or lapse of any restriction with respect to, any Override Units granted to such Member.

     (c) If the Company makes a distribution in kind and such distribution is subject to withholding or other taxes payable by the Company on behalf of any Member, such Member shall make a prompt payment to the Company of the amount of such withholding or other taxes by wire transfer.

     Section 9.5 Restricted Distributions. Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Member on account of its Interest if such distribution would violate Section 18-607 of the Delaware Act or other applicable law.

     Section 9.6 Tax Distributions. In the event that the Company sells an equity interest in a Subsidiary, resulting in taxable income being recognized by the Members, or the Members are otherwise allocated taxable income from the Company (in each case, other than upon an Exit Event), the Company may make distributions to the Members to the extent of available cash (as determined by the Board in its discretion) in an amount equal to such income multiplied by a reasonable tax rate determined by the Override Unit Committee; it being understood that, if the Members are allocated material taxable income without corresponding cash distributions sufficient to pay the resulting tax liabilities, it is the Company’s intention to make the tax distributions referred to herein; provided that the Board in its sole discretion shall determine whether any such tax distributions will be made. Any distributions made to a Member pursuant to this Section 9.6 shall reduce the amount otherwise distributable to such Member pursuant to the other provisions of this Agreement, so that to the maximum extent possible, the total amount of distributions received by each Member pursuant to this Agreement at any time is the same as such Member would have received if no distribution had been made pursuant to this Section 9.6. To the extent the cumulative sum of tax distributions made to a Member under this Section 9.6 has not been applied pursuant to the preceding sentence to reduce other amounts distributable to such Member, such Member shall contribute to the Company the remaining amounts necessary to give full effect to the preceding sentence on the date of the final liquidating distribution made by the Company pursuant to Section 13.2.

Within 90 days after the end of each taxable year (or as soon as reasonably practicable thereafter), the Company shall send to each Person that was a Member at any time during such year copies of Schedule K-1, “Partner’s Share of Income, Credits, Deductions, Etc.”, or any successor schedule or form, with respect to such Person, together with such additional information as may be necessary for such Person to file his, her or its United States federal income tax returns.

     (b) GSCP Onshore shall be the tax matters partner of the Company, within the meaning of section 6231 of the Code (the “Tax Matters Partner”) unless a Majority in Interest votes otherwise; provided that the Tax Matters Partner shall give prompt notice to Kelso of any item or event with respect to taxes, including a proposed administrative or judicial proceeding involving taxes, and any proposed deficiency or similar notice of intention to assess taxes that could have more than an immaterial affect on Kelso. The Tax Matters Partner will not take any action that could be reasonably expected to have an affect on Kelso that is not immaterial without Kelso’s consent. Each Member hereby consents to such designation and agrees that upon the request of the Tax Matters Partner, such Member will execute, certify, acknowledge, deliver, swear to, file and record at the appropriate public offices such documents as may be necessary or appropriate to evidence such consent.

     (c) Promptly following the written request of the Tax Matters Partner, the Company shall, to the fullest extent permitted by applicable law, reimburse and indemnify the Tax Matters Partner for all reasonable expenses, including reasonable legal and accounting fees, claims, liabilities, losses and damages incurred by the Tax Matters Partner in connection with any administrative or judicial proceeding with respect to the tax liability of the Members, except to the extent arising from the bad faith, gross negligence, willful violation of law, fraud or breach of this Agreement by such Tax Matters Partner.

     (d) The provisions of this Section 10.2 shall survive the termination of the Company or the termination of any Member’s Interest and shall remain binding on the Members for as long a period of time as is necessary to resolve with the Internal Revenue Service any and all matters regarding the U.S. federal income taxation of the Company or the Members.

     Section 10.3 Accounting Method. For both financial and tax reporting purposes, the books and records of the Company shall be kept on the accrual method of accounting applied in a consistent manner and shall reflect all Company transactions and be appropriate and adequate for the Company’s business.

     Section 11.3 Fiduciary Duty. Any duties (including fiduciary duties) of a Covered Person to the Company or to any other Covered Person that would otherwise apply at law or in equity are hereby eliminated to the fullest extent permitted under the Delaware Act and any other applicable law; provided that (a) the foregoing shall not eliminate the obligation of each Covered Person to act in compliance with the express terms of this Agreement and (b) the foregoing shall not be deemed to eliminate the implied contractual covenant of good faith and fair dealing. Notwithstanding anything to the contrary contained in this Agreement, each of the Members hereby acknowledges and agrees that each of the Directors, in determining whether or not to vote in support of or against any particular decision for which the Board’s consent is required, may act in and consider the best interest of the Member who designated such Director and shall not be required to act in or consider the best interests of the Company or the other Members or parties hereto.

To the fullest extent permitted by applicable law, a Covered Person shall be entitled to indemnification from the Company for any loss, damage or claim incurred by such Covered Person by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company and in a manner believed to be within the scope of authority conferred on such Covered Person by this Agreement, except that no Covered Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Covered Person by reason of such Covered Person’s gross negligence, willful misconduct or willful breach of this Agreement with respect to such acts or omissions; provided, that any indemnity under this Section 11.4 shall be provided out of and to the extent of Company assets only, and no Covered Person shall have any personal liability on account thereof.

     Section 11.5 Expenses. To the fullest extent permitted by applicable law, expenses (including, without limitation, reasonable attorneys’ fees, disbursements, fines and amounts paid in settlement) incurred by a Covered Person in defending any claim, demand, action, suit or proceeding relating to or arising out of their performance of their duties on behalf of the Company shall, from time to time, be advanced by the Company prior to the final disposition of

such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Covered Person to repay such amount if it shall ultimately be determined by a court of competent jurisdiction that the Covered Person is not entitled to be indemnified as authorized in this Section 11.5.

     Section 11.6 Severability. To the fullest extent permitted by applicable law, if any portion of this Article shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify each Director or Officer and may indemnify each employee or agent of the Company as to costs, charges and expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Company, to the fullest extent permitted by any applicable portion of this Article XI that shall not have been invalidated.

     Section 12.2 Overriding Provisions.

     (a) Any Transfer in violation of this Article XII shall be null and void ab initio, and the provisions of Section 12.2(e) shall not apply to any such Transfers. The approval of any Transfer in any one or more instances shall not limit or waive the requirement for such approval in any other or future instance.

     (b) All Transfers permitted under this Article XII are subject to this Section 12.2 and Sections 12.5 and 12.6.

     (c) Any proposed Transfer by a Member pursuant to the terms of this Article XII shall, in addition to meeting all of the other requirements of this Agreement, satisfy the following conditions: (i) the Transfer will not be effected on or through an “established securities market” or a “secondary market or the substantial equivalent thereof,” as such terms are used in Treasury Regulations section 1.7704-1, and, at the request of the Board, the transferor and the transferee will have each provided the Company a certificate to such effect; and (ii) the proposed transfer will not result in the Company having more than 99 Members, within the meaning of Treasury Regulations section 1.7704-1(h)(1) (determined pursuant to the rules of Treasury Regulations section 1.7704-1(h)(3)). The Board may in its sole discretion waive the condition set forth in clause (ii) of this Section 12.2(c).

     (d) The Company shall promptly amend Schedule A to reflect any permitted transfers of Interests pursuant to and in accordance with this Article XII.

     (e) The Company shall, from the effective date of any permitted assignment of an Interest (or part thereof), thereafter pay all further distributions on account of such Interest (or part thereof) to the assignee of such Interest (or part thereof); provided that such assignee shall have no right or powers as a Member unless such assignee complies with Section 12.6.

     Section 12.3 Estate Planning Transfers; Transfers upon Death of a Management Member. Interests held by Management Members may be transferred for estate-planning purposes of such Management Member, to (A) a trust under which the distribution of the Interests may be made only to beneficiaries who are such Management Member, his or her spouse, his or her parents, members of his or her immediate family or his or her lineal descendants, (B) a charitable remainder trust, the income from which will be paid to such Management Member during his or her life, (C) a corporation, the shareholders of which are only such Management Member, his or her spouse, his or her parents, members of his or her immediate family or his or her lineal descendants or (D) a partnership or limited liability company, the partners or members of which are only such Management Member, his or her spouse, his or her parents, members of his or her immediate family or his or her lineal descendants. Interests may be transferred as a result of the laws of descent; provided that, in each such case, such Management Member provides prior written notice to the Board of such proposed Transfer and makes available to the Board documentation, as the Board may reasonably request, in order to verify such Transfer.

     Section 12.4 Involuntary Transfers. Any transfer of title or beneficial ownership of Interests upon default, foreclosure, forfeit, divorce, court order or otherwise than by a voluntary

decision on the part of a Management Member or Outside Member (each, an “Involuntary Transfer”) shall be void unless the Management Member or Outside Member complies with this Section 12.4 and enables the Company to exercise in full its rights hereunder. Upon any Involuntary Transfer, the Company shall have the right to purchase such Interests pursuant to this Section 12.4 and the Person to whom such Interests have been Transferred (the “Involuntary Transferee”) shall have the obligation to sell such Interests in accordance with this Section 12.4. Upon the Involuntary Transfer of any Interest, such Management Member or an Outside Member shall promptly (but in no event later than two days after such Involuntary Transfer) furnish written notice to the Company indicating that the Involuntary Transfer has occurred, specifying the name of the Involuntary Transferee, giving a detailed description of the circumstances giving rise to, and stating the legal basis for, the Involuntary Transfer. Upon the receipt of the notice described in the preceding sentence, and for 60 days thereafter, the Company shall have the right to purchase, and the Involuntary Transferee shall have the obligation to sell, all (but not less than all) of the Interests acquired by the Involuntary Transferee for a purchase price equal to the lesser of (i) the Fair Market Value of such Interest and (ii) the amount of the indebtedness or other liability that gave rise to the Involuntary Transfer plus the excess, if any, of the Carrying Value of such Interests over the amount of such indebtedness or other liability that gave rise to the Involuntary Transfer. Notwithstanding anything to the contrary, any Involuntary Transfer of Override Units shall result in the immediate forfeiture of such Override Units and without any compensation therefor, and such Involuntary Transferee shall have no rights with respect to such Override Units.

     Section 12.5 Assignments.

     (a) Assignment by the Company. The Company shall have the right to assign to GSCP and Kelso, on a pro rata basis, all or any portion of its rights and obligations under Section 12.4; provided that any such assignment or assumption is accepted by both GSCP and Kelso. If the Company has not exercised its right to purchase Interests pursuant to such Section 12.4 within 15 days of receipt by the Company of the letter, notice or other occurrence giving rise to such right, then GSCP and Kelso shall have the right to jointly require the Company to assign such right. GSCP shall have the right to assign to one or more of the GSCP Members all or any of its rights to purchase Interests pursuant to this Section 12.5(a). Kelso shall have the right to assign to one or more of the Kelso Members all or any of its rights to purchase Interests pursuant to this Section 12.5(a).

     (b) Assignment Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the Members hereto and their respective heirs, legal representatives, successors and assigns; provided (i) that no Non-Investor Member may assign any of its rights or obligations hereunder without the consent of GSCP and Kelso unless such assignment is in connection with a Transfer explicitly permitted by this Agreement and, prior to such assignment, such assignee complies with the requirements of Section 12.6, (ii) that no Investor Member may assign any of its rights or obligations hereunder without the consent of GSCP (if a Kelso Member is the assigning Investor Member) or Kelso (if GSCP is the assigning Investor Member), as the case may be, unless such assignment is in connection with a Transfer explicitly permitted by this Agreement, and prior to such assignment, such assignee complies with the requirements of Section 12.6 and (iii) that the rights of GSCP and Kelso pursuant to Section 3.7,

Section 4.12, Section 12.8 and Section 12.9 may only be assigned as a whole and not in part (and otherwise in accordance with the provisions of clause (ii) of this proviso).

     Section 12.6 Substitute Members. In the event any Non-Investor Member or Investor Member Transfers its Interest in compliance with the other provisions of this Article XII (other than Section 12.4), the transferee thereof shall have the right to become a substitute Non-Investor Member or substitute Investor Member, as the case may be, but only upon satisfaction of the following:

     (a) execution of such instruments as the Board deems reasonably necessary or desirable to effect such substitution; and

     (b) acceptance and agreement in writing by the transferee of the Member’s Interest to be bound by all of the terms and provisions of this Agreement and assumption of all obligations under this Agreement (including breaches hereof) applicable to the transferor and in the case of a transferee of a Management Member who resides in a state with a community property system, such transferee causes his or her spouse, if any, to execute a Spousal Waiver in the form of Exhibit A attached hereto. Upon the execution of the instrument of assumption by such transferee and, if applicable, the Spousal Waiver by the spouse of such transferee, such transferee shall enjoy all of the rights and shall be subject to all of the restrictions and obligations of the transferor of such transferee.

     Section 12.7 Release of Liability. In the event any Member shall sell such Member’s entire Interest (other than in connection with an Exit Event) in compliance with the provisions of this Agreement, including, without limitation, pursuant to the penultimate sentence of Section 12.4, without retaining any interest therein, directly or indirectly, then the selling Member shall, to the fullest extent permitted by applicable law, be relieved of any further liability arising hereunder for events occurring from and after the date of such Transfer.

     Section 12.8 Right of First Offer; Tag-Along and Drag-Along Rights.

     (a) Right of First Offer. Any Transfers by either GSCP or Kelso (such Investor Member, in such capacity, a “Transferring Investor Member”), other than any Transfer described in clauses (x) or (y) of Section 12.1(a), shall be consummated only in accordance with the following procedures:

     (i) The Transferring Investor Member shall first deliver to the Company a written notice (a “First Offer Notice”), which shall (x) state the Transferring Investor Member’s intention to Transfer Interests to one or more Persons, the amount and type of Interests to be sold (the “Subject Interests”), the purchase price therefor and a summary of the other material terms of the proposed Transfer and (y) offer to the Company and the Other Investor Member the right to acquire all or a portion of such Subject Interests upon the terms and subject to the conditions of the proposed Transfer as set forth in the First Offer Notice (the “First Offer”); provided that such First Offer may provide that it must be accepted by the Company and the Other Investor Members (in the aggregate) on an all or nothing basis (an “All or Nothing Offer”). The First Offer shall remain open and irrevocable for the periods set forth below (and, to the extent the First Offer is accepted

during such periods, until the consummation of the Transfer contemplated by the First Offer). The Company shall have the right, for a period of 20 days after delivery of the First Offer Notice (the “Initial First Offer Acceptance Period”), to accept the First Offer for all or any part of the Subject Interests at the purchase price and on the other terms stated in the First Offer Notice. Such acceptance shall be made by delivering a written notice to the Transferring Investor Member and the Other Investor Member within the Initial First Offer Acceptance Period.

     (ii) If the Company shall fail to accept all of the Subject Interests offered for Sale pursuant to, or shall reject in writing, the First Offer (the Company being required to notify in writing the Transferring Investor Member and the Other Investor Member of its rejection or failure to accept in the event of the same), then, upon the earlier of the expiration of the Initial First Offer Acceptance Period or the giving of such written notice of rejection or failure to accept such offer by the Company, the Other Investor Member shall have the right, for a period of 15 days thereafter (the “Additional First Offer Acceptance Period”), to accept the First Offer for all or any part of the Subject Interests so offered and not accepted by the Company (the “Refused Interests”) at the purchase price and on the other terms stated in the First Offer Notice; provided, however, that, if the First Offer is an All or Nothing Offer, the Other Investor Member may accept, during the Additional First Offer Acceptance Period, all, but not less than all, of the Refused Interests, at the purchase price and on the terms stated in the First Offer Notice. Such acceptance shall be made by delivering a written notice to the Company and the Transferring Investor Member within the Additional First Offer Acceptance Period specifying the maximum number of Interests such Other Investor Member will purchase.

     (iii) If effective acceptance shall not be received pursuant to Sections 12.8(a)(i) and/or 12.8(a)(ii) above with respect to all of the Subject Interests offered pursuant to the First Offer Notice, then the Transferring Investor Member may Transfer all or any portion of the Interests so offered and not so accepted (or, in the case of an All or Nothing Offer, all of the Subject Interests offered pursuant to the First Offer Notice), at a price not less than the price, and on terms not more favorable to the purchaser thereof than the terms, stated in the First Offer Notice at any time within 90 days (plus a sufficient number of days to allow the expiration or termination of all waiting periods under HSR (as defined below) applicable to such Transfer) after the expiration of the Additional First Offer Acceptance Period (the “Transfer Period”). To the extent the Transferring Investor Member Transfers all or any portion of the Interests so offered during the Transfer Period, the Transferring Investor Member shall promptly notify the Company, and the Company shall promptly notify the Other Investor Member, as to (i) the number of Interests, if any, that the Transferring Investor Member then owns, (ii) the number of Interests that the Transferring Investor Member has Transferred, (iii) the terms of such Transfer and (iv) the name of the Person(s) to whom any Interests were Transferred. In the event that all of the Interests are not Transferred by the Transferring Investor Member during the Transfer Period, the right of the Transferring Investor Member to Transfer such Interests which are not Transferred shall expire and the obligations of this Section 12.8(a) shall be reinstated; provided, however, in the event that the Transferring Investor Member determines, at any time during the Transfer Period, that the Transfer of all of the Interests on the terms set forth in the First Offer Notice is

impractical, the Transferring Investor Member may terminate the offer and reinstate the procedure provided in this Section 12.8(a) without waiting for the expiration of the Transfer Period; provided that such Transferring Investor Member has not previously done so within the preceding six month period.

     (iv) All Transfers of Subject Interests to the Company and/or the Other Investor Member subject to any First Offer Notice shall be consummated contemporaneously at the offices of the Company on the later of (i) a mutually satisfactory business day within 15 days after the expiration of the Initial First Offer Acceptance Period, or the Additional First Offer Acceptance Period, as applicable, and (ii) the fifth business day following the expiration or termination of all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (“HSR”), applicable to such Transfers, or at such other time and/or place as the parties to such Transfers may agree. The delivery of certificates or other instruments evidencing such Subject Interests duly endorsed for transfer shall be made on such date against payment of the purchase price for such Subject Interests.

     (v) Anything contained herein to the contrary notwithstanding, prior to any Transfer of Interests by a Transferring Investor Member pursuant to this Section 12.8(a), the Transferring Investor Member shall, after complying with the provisions of this Section 12.8(a), comply with the provisions of Section 12.8(b) hereof, if applicable.

     (b) Tag-Along Rights. In the event that a Selling Investor Member proposes to Transfer Interests, other than any Transfer to an Affiliate of such Selling Investor Member, and such Interests would represent, together with all Interests previously Transferred by such Selling Investor Member to non-Affiliates of such Selling Investor Member, more than 10% of such Selling Investor Member’s Common Units held on the date hereof, then at least thirty (30) days prior to effecting such Transfer, such Selling Investor Member shall give each other Member written notice of such proposed Transfer. Each other Member shall then have the right (the “Tag-Along Right”), exercisable by written notice to the Selling Investor Member, to participate pro rata in such sale by selling a pro rata portion of such other Member’s Common Units on substantially the same terms (including with respect to representations, warranties and indemnification) as the Selling Investor Member; provided, however, that (x) any representations and warranties relating specifically to any Member shall only be made by that Member; (y) any indemnification provided by the Members (other than with respect to the representations referenced in the foregoing subsection (x)) shall be based on the relative Interests being sold by each Member in the proposed sale, either on a several, not joint, basis or solely with recourse to an escrow established for the benefit of the proposed purchaser (the Members’ contributions to such escrow to be on a pro-rata basis in accordance with the proceeds received from such sale), it being understood and agreed that any such indemnification obligation of an Member shall in no event exceed the net proceeds to such Member from such proposed Transfer; and (z) the form of consideration to be received by the Selling Investor Member in connection with the proposed sale may be different from that received by the other Members so long as the value of the consideration to be received by the Selling Member is the same or less than what they would have received had they received the same form of consideration as the other Members. In the event that a sale by the Selling Member does not constitute an Exit Event then, unless otherwise

determined by the Override Unit Committee in its sole discretion, Management Members may only participate in such sale with respect to their Common Units.

     (c) Drag-Along Rights. (i) In the event that on or after the fifth anniversary hereof a Selling Investor Member owning, alone or together with any other Member, more than 30% of the then outstanding Common Units (A) proposes to Transfer Interests, other than any Transfer to an Affiliate of such Selling Investor Member, and such Interests would represent more than 30% of the then outstanding Common Units, or (B) desires to effect an Exit Event, such Selling Investor Member shall have the right (the “Drag-Along Right”), upon written notice to the other Members, to require that each other Member join pro rata in such sale by selling a pro rata portion of such other Member’s Common Units on substantially the same terms (including with respect to representations, warranties and indemnification) as such Selling Investor Member; provided, however, that (x) any representations and warranties relating specifically to any Member (other than with respect to the representations referenced in the foregoing subsection (x)) shall only be made by that Member; (y) any indemnification provided by the Members shall be based on the relative purchase price being received by each Member in the proposed sale, either on a several, not joint, basis or solely with recourse to an escrow established for the benefit of the proposed purchaser (the Members’ contributions to such escrow to be on a pro rata basis in accordance with the proceeds received from such sale), it being understood and agreed that any such indemnification obligation of a Member shall in no event exceed the net proceeds to such Member from such proposed Transfer; and (z) the form of consideration to be received by the Selling Investor Member in connection with the proposed sale may be different from that received by the other Members so long as the value of the consideration to be received by the Selling Investor Member is the same or less than what they would have received had they received the same form of consideration as the other Members (as reasonably determined by the Board in good faith). For purposes of this Section 12.8, for each Member “joining the Selling Investor Member in such sale” shall include voting its Interests consistently with the Selling Investor Member, transferring its Interests to a corporation organized in anticipation of such sale in exchange for capital stock of such corporation, executing and delivering agreements and documents which are being executed and delivered by the Selling Investor Member and providing such other cooperation as the Selling Investor Member may reasonably request.

     (ii) Any Exit Event may be structured as an auction and may be initiated by the delivery to the Company and the other Members of a written notice that the Selling Investor Member has elected to initiate an auction sale procedure. The Selling Investor Member shall be entitled to take all steps reasonably necessary to carry out an auction of the Company, including, without limitation, selecting an investment bank, providing confidential information (pursuant to confidentiality agreements), selecting the winning bidder and negotiating the requisite documentation. The Company and each Member shall provide assistance with respect to these actions as reasonably requested.

     (iii) In the event the Selling Investor Member sells less than 100% of its Common Units in the Company, joining “pro rata in such sale” shall be based on relative Common Units unless the Override Unit Committee in its sole discretion determines that the Override Units shall participate in the sale, in which case the principles of clause (iv) of this Section 12.8(c) shall apply.

     (iv) In the event that an Exit Event is structured as a sale of Interests by the Members, rather than a sale of the Company’s assets with a subsequent distribution of proceeds by the Company, then the purchase agreement governing such Interest sale will have provisions therein which replicate, to the greatest extent possible, the economic result which would have been attained under Articles IX and XIII had the Exit Event been structured as a sale of the Company’s assets and a distribution of proceeds.

     (d) Any transaction costs, including transfer taxes and legal, accounting and investment banking fees incurred by the Company and the Selling Investor Member in connection with an Exit Event shall, unless the applicable purchaser refuses, be borne by the Company in the event of a merger, consolidation or sale of assets and shall otherwise be borne by the Members on a pro rata basis based on the consideration received by each Member in such Exit Event.

     Section 12.9 Initial Public Offering.

     (a) Generally. Upon (i) a joint determination by both GSCP and Kelso or (ii) following the third anniversary of the date hereof, a determination by either GSCP or Kelso to effect an Initial Public Offering, the Board and each other Member shall take such actions as are necessary to structure the IPO in a manner acceptable to such Investor Members or such Investor Member, as the case may be, including, without limitation, causing the public offering of the stock of an existing or newly formed Subsidiary of the Company (a “Subsidiary IPO”) or effecting any Transfers, mergers, consolidations or restructurings pursuant to Section 12.9(b) and making any such amendments to this Agreement as may be deemed by such Investor Members or such Investor Members, as the case may be, to be necessary to facilitate such IPO; provided that, if only one of GSCP or Kelso requests any of the foregoing actions to be taken, any such action, to the extent it would adversely impact the other Investor Member (Kelso or GSCP, as the case may be) in a manner differently than it impacts the requesting Investor Member, shall be subject to the prior approval of such other Investor Member, such approval not to be unreasonably withheld.

     (b) IPO of Newco or the Company. In the event that both GSCP and Kelso or either GSCP or Kelso request an IPO pursuant to Section 12.9(a) above, the parties or party requesting such IPO can require in order to facilitate such IPO (i) a Transfer of all or substantially all of (x) the assets of the Company or (y) the Interests to a newly organized stock corporation or other business entity (“Newco”), (ii) a merger of the Company into Newco by merger or consolidation or (iii) any other restructuring of the Interests, in any such case in anticipation of an Initial Public Offering, and each Member shall take such steps to effect such Transfer, merger, consolidation or other restructuring as may be requested by such Investor Members or Investor Member, as the case may be, or as may be requested by the Company, including, without limitation, Transferring such Member’s Interests to Newco in exchange for capital stock of Newco; provided, that, in the event of such an exchange, each Interest would be exchanged for a number of shares of Newco stock determined in a manner such that each Member is treated no less favorably than such Member would have been treated upon an Exit Event (assuming the value of the consideration to be received by such Investor Members or such Investor Member, as the case may be, in the Exit Event is the mid-point of the filing range in the IPO); and provided, further, in lieu of effecting such exchange of the Common Units (and/or at the option and request of such Investor Members or Investor Member, as the case may be, Override Units) of Management Members, the

Company shall, at the request of such Investor Members or Investor Member, as the case may be, pay to the Management Members cash in an amount equal to the aggregate Fair Market Value of the shares such Management Member would, otherwise, have received pursuant to the preceding proviso. Notwithstanding the preceding sentence, no Member shall be required to take any action or omit to take any action to the extent such action or omission violates applicable law. If GSCP and Kelso or either of them determines to effect an IPO pursuant to this Section 12.9 and the Members receive shares of Newco pursuant to any such Transfer, merger, consolidation or restructuring, (i) each other Member agrees to enter (as an “Investor Stockholder,” “Management Stockholder” or “Outside Stockholder,” respectively, as set forth therein) into a Registration Rights Agreement substantially in the form of Exhibit C hereto, which Registration Rights Agreement shall set forth the respective rights and obligations of the parties with respect to participating in such IPO of Newco and (ii) this Agreement shall automatically terminate upon an IPO of Newco or the Company.

     (c) Subsidiary IPO. In the event that both GSCP and Kelso or either GSCP or Kelso request an IPO pursuant to Section 12.9(a) and elect that such IPO occur through a Subsidiary IPO, then (i) this Agreement shall continue to remain in full force and effect with any amendments or modifications thereto as shall be effectuated by the Investor Members or Investor Member requesting such IPO in accordance with Section 12.9(a) above; provided that, following such Subsidiary IPO (A) the governance provisions herein shall apply only with respect to the Company and not with respect to any Subsidiary of the Company, (B) the Company shall not vote any shares of such existing or newly formed Subsidiary in favor of any action without the prior written consent of (I) either GSCP or at least one GSCP Director for so long as GSCP continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount and (II) either Kelso or at least one Kelso Director for so long as Kelso continues to hold an amount of Common Units that represents both the Requisite Outstanding Amount and the Requisite Original Amount, and (C) the provisions of Article XII (other than this Section 12.9) shall cease to apply, (ii) the Company and such existing or newly formed Subsidiary shall enter into a Registration Rights Agreement that is substantially similar to the Registration Rights Agreement attached as Exhibit C hereto, except that such Registration Rights Agreement will provide for rights of the Company to request registrations of its equity interests in such existing or newly formed Subsidiary (and to piggyback on such registrations) rather than providing for the rights of Members to participate directly in public offerings and (iii) the Members shall amend this Agreement or enter into such ancillary agreements as they deem necessary to permit such Members to achieve liquidity with respect to their Interest in the Company (indirectly, through the Company’s exercise of its registration rights in such existing or newly formed Subsidiary and through the Company’s use of the proceeds resulting therefrom to redeem Units from Members) to the same extent as they would have been entitled to do had there been an IPO of Newco rather than a Subsidiary IPO.

     Notwithstanding the foregoing, the death, retirement, resignation, expulsion, bankruptcy or dissolution of any Member or the occurrence of any other event that terminates the continued membership of any Member in the Company under the Delaware Act shall not, in and of itself, cause the dissolution of the Company. In such event, the remaining Member(s) shall continue the business of the Company without dissolution.

Upon the dissolution of the Company, the assets of the Company shall be liquidated or distributed under the direction of, and to the extent determined by, the Board, and the business of the Company shall be wound up. Within a reasonable time after the effective date of dissolution of the Company, the Company’s assets shall be distributed in the following manner and order:

     First, to creditors in satisfaction of indebtedness (other than any loans or advances that may have been made by any of the Members to the Company), whether by payment or the making of reasonable provision for payment, and the expenses of liquidation, whether by payment or the making of reasonable provision for payment, including the establishment of reasonable reserves (which may be funded by a liquidating trust) determined by the Board or the liquidating trustee, as the case may be, to be reasonably necessary for the payment of the Company’s expenses, liabilities and other obligations (whether fixed, conditional, unmatured or contingent);

     Second, to the payment of loans or advances that may have been made by any of the Members to the Company; and

     Third, to the Members in accordance with Section 9.1, taking into account any amounts previously distributed under Section 9.1;

     provided that no payment or distribution in any of the foregoing categories shall be made until all payments in each prior category shall have been made in full, and provided, further, that, if the payments due to be made in any of the foregoing categories exceed the remaining assets available for such purpose, such payments shall be made to the Persons entitled to receive the same pro rata in accordance with the respective amounts due to them.

     Section 13.3 Distributions in Cash or in Kind. Upon the dissolution of the Company, the Board shall use all commercially reasonable efforts to liquidate all of the Company’s assets in an orderly manner and apply the proceeds of such liquidation as set forth in Section 13.2; provided that, if in the good faith judgment of the Board, a Company asset should not be liquidated, the Board shall cause the Company to allocate, on the basis of the Fair Market Value of any Company assets not sold or otherwise disposed of, any unrealized gain or loss based on such value to the Members’ Capital Accounts as though the assets in question had been sold on

the date of distribution and, after giving effect to any such adjustment, distribute such assets in accordance with Section 13.2 as if such Fair Market Value had been received in cash, subject to the priorities set forth in Section 13.2, and provided, further, that the Board shall in good faith attempt to liquidate sufficient Company assets to satisfy in cash (or make reasonable provision for) the debts and liabilities referred to in Section 13.2.

     Section 13.4 Termination. The Company shall terminate when the winding up of the Company’s affairs has been completed, all of the assets of the Company have been distributed and the Certificate has been canceled, all in accordance with the Delaware Act.

The Members and former Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members and former Members shall have no recourse against the Company or any other Member.

Notwithstanding the foregoing, no amendment, modification or supplement shall adversely affect the Management Members as a class without the consent of a Majority in Interest (exclusive of Override Units) of the Management Members or, to the extent (and only to the extent) any particular Management Member would be uniquely and adversely affected by a proposed amendment, modification or supplement, by such Management Member;

provided, however, that, in either case, no such consent shall be required for (i) any amendments, modifications or supplements to Article IV, (ii) any amendments, modifications or supplements effectuated pursuant to Section 12.9, or (iii) for the issuance of additional Units pursuant to Article III.

Such remedies shall, however, be cumulative and not exclusive, and shall be in addition to any other remedy which the Company or any Member may have. Each Member hereby irrevocably submits to the non-exclusive jurisdiction of the state and federal courts in New York for the purposes of any suit, action or other proceeding arising out of, or based upon, this Agreement or the subject matter hereof.
