NOW, THEREFORE, in consideration of the premises and the covenants and provisions hereinafter contained, the Members hereby amend and restate the Original Agreement in its entirety and adopt the following:

“Annual Monitoring Fee” means (i) an annual monitoring fee to be paid to each Investor other than any DLJ Member (or such other entity designated by such Investor) equal to the lesser of (a) the product of (x) such Investor’s Class A Unit Sharing Percentage and (y) $150,000 and (b) 1% of the total Capital Contributions made by such Investor and (ii) an annual monitoring fee to be paid to the DLJ Representative (or such other entity designated by the DLJ Representative) equal to the lesser of (a) the product of (x) the DLJ Group’s aggregate Class A Unit Sharing Percentage and (y) $150,000 and (b) 1% of the aggregate Capital Contributions made by the DLJ Group. For purposes of this definition of “Annual Monitoring Fee,” (i) each Investor other than any DLJ Member and (ii) the DLJ Representative shall be referred to as a “Fee Payee.” During the Commitment Period, the Annual Monitoring Fee will be paid on an annual basis concurrent with and offset against the first cash Capital Contribution made by each Fee Payee in such calendar year; provided, however, (A) that in the event the Annual Monitoring Fee payable to a Fee Payee exceeds the first cash Capital Contribution made by such Fee Payee in any calendar year, then any future cash Capital Contribution to be made by such Fee Payee in such calendar year shall be offset by the balance thereof until the full amount of the Annual Monitoring Fee has been offset against such Fee Payee’s cash Capital Contributions for such calendar year, (B) the Capital Account of each such Fee Payee shall be credited with Capital Contributions determined without reduction by any offset of the Annual Monitoring Fee contemplated herein, and (C) in the event that (1) any such Fee Payee does not make a cash

For the avoidance of doubt, the Annual Monitoring Fee payable to the DLJ Representative will not offset or otherwise affect any Capital Contribution to be made by any other DLJ Member.

Each Class A Member must exercise such participation right within forty-five (45) days from the date such Class A Member receives a Covered Opportunity Notice (the “Response Date”). Such participation right shall be extended by the delivery by the Executive Management Team to the Class A Members of a notice (a “Covered Opportunity Notice”) setting forth the identity and size of the transaction and the maximum amount of funding required or available for investment. With respect to any Covered Opportunity, the terms of any investment by the Class A Members shall be on terms substantially similar to the terms agreed upon with other investors as of the date of the Covered Opportunity Notice, which shall be set forth in the Covered Opportunity Notice, or in the event that there are no other anticipated investors as of the date of the Covered Opportunity Notice, upon terms that are consistent with the then current market terms for similar transactions, both in size and type of investment, as the Class A Members and the participating members of the Executive Management Team may mutually agree (and in the event of any disagreements, the

In the event that a Class A Member does not deliver an Acceptance Notice prior to the Response Date, such Class A Member will be deemed to have rejected the right to participate in such Covered Opportunity on the terms and conditions set forth in the Covered Opportunity Notice; provided, however, in no event shall such Covered Opportunity be offered to third parties on terms or conditions materially different than those set forth in the Covered Opportunity Notice. If any terms or conditions materially change or differ from those set forth in the Covered Opportunity Notice, said Covered Opportunity must then be resubmitted to the Class A Members on the basis of the changed terms and conditions and the Class A Members shall have forty-five (45) days from receipt of the revised Covered Opportunity Notice to consider such Covered Opportunity. Subject to full compliance with the terms of this Section 4.04 and any other terms and provisions of this Agreement applicable at the time, nothing contained herein shall prevent the Executive Management Team from having discussions concerning potential financing opportunities with third parties during the period beginning on the date of the Covered Opportunity Notice and continuing until the earlier of the Response Date or the date of any Acceptance Notice. If no Acceptance Notice is received in a timely manner, then the Executive Management Team shall be free to explore or consummate financing opportunities from third parties. Notwithstanding anything in this Section 4.04 to the contrary, in the event that a member of the Executive Management Team’s employment with the Company is terminated by the Company other than for Good Cause or is terminated by such Member for Good Reason prior to a Liquidation Event, this Section 4.04 shall not apply to such member of the Executive Management Team.

ALLOCATIONS

Section 8.01 Allocations of Profits and Losses. After giving effect to the Regulatory Allocations, and subject to Section 16.03(b) of this Agreement, Profits and Losses (and to the extent necessary to achieve the resulting Capital Account balances described below, any allocable items of gross income, gain, loss and expense includable in the computation of Profits and Losses) for each Fiscal Period shall be allocated among the Members during such Fiscal Period, in such a manner as shall cause the Capital Accounts of the Members (as adjusted to reflect all Regulatory Allocations and all distributions through the end of such Fiscal Period) to equal, as nearly as possible, (a) the amount such Members would receive if all assets of the Company on hand at the end of such Fiscal Period were sold for cash equal to their Book Values, all liabilities of the Company were satisfied in cash in accordance with their terms (limited in the case of non-recourse liabilities to the Book Value of the property securing such liabilities), all unvested Series B Units became vested, and all remaining or resulting cash (including any Retained Distributions) were distributed to the Members under Section 9.01 of this Agreement minus (b) such Member’s share of Minimum Gain and Member Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets.

Section 8.02 Regulatory Allocations. The following allocations shall be made in the following order:

(a) Nonrecourse Deductions shall be allocated 87.5% to the holders of Series A Units in proportion to their respective Class A Unit Sharing Percentages and 12.5% to the holders of Series B Units pro rata in proportion to their respective Class B Unit Sharing Percentages.

(b) Member Nonrecourse Deductions attributable to Member Nonrecourse Debt shall be allocated to the Members bearing the Economic Risk of Loss for such Member

Nonrecourse Debt as determined under Treasury Regulation Section 1.704-2(b)(4). If more than one Member bears the Economic Risk of Loss for such Member Nonrecourse Debt, the Member Nonrecourse Deductions attributable to such Member Nonrecourse Debt shall be allocated among the Members according to the ratio in which they bear the Economic Risk of Loss. This Section 8.02(b) is intended to comply with the provisions of Treasury Regulation Section 1.704-2(i) and shall be interpreted consistently therewith.

(c) Notwithstanding any other provision hereof to the contrary, if there is a net decrease in Minimum Gain for a Fiscal Period (or if there was a net decrease in Minimum Gain for a prior Fiscal Period and the Company did not have sufficient amounts of income and gain during prior periods to allocate among the Members under this Section 8.02(c)), items of income and gain shall be allocated to each Member in an amount equal to such Member’s share of the net decrease in such Minimum Gain (as determined pursuant to Treasury Regulation Section 1.704-2(g)(2)). This Section 8.02(c) is intended to constitute a minimum gain chargeback under Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(d) Notwithstanding any provision hereof to the contrary except Section 8.02(c) (dealing with Minimum Gain), if there is a net decrease in Member Nonrecourse Debt Minimum Gain for a Fiscal Period (or if there was a net decrease in Member Nonrecourse Debt Minimum Gain for a prior Fiscal Period and the Company did not have sufficient amounts of income and gain during prior periods to allocate among the Members under this Section 8.02(d)), items of income and gain shall be allocated to each Member in an amount equal to such Member’s share of the net decrease in Member Nonrecourse Debt Minimum Gain (as determined pursuant to Treasury Regulation Section 1.704-2(i)(4)). This Section 8.02(d) is intended to constitute a partner nonrecourse debt minimum gain chargeback under Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(e) Notwithstanding any provision hereof to the contrary except Section 8.02(a) and Section 8.02(b), no Losses or other items of loss or expense shall be allocated to any Member to the extent that such allocation would cause such Member to have a deficit balance in its Adjusted Capital Account (or increase any existing deficit balance in its Adjusted Capital Account) at the end of such Fiscal Period. All Losses and other items of loss and expense in excess of the limitation set forth in this Section 8.02(e) shall be allocated to the Members who do not have a deficit balance in their Adjusted Capital Accounts in proportion to their relative positive Adjusted Capital Accounts but only to the extent that such Losses and other items of loss and expense do not cause any such Member to have a deficit in its Adjusted Capital Account.

(f) Notwithstanding any provision hereof to the contrary except Section 8.02(c), Section 8.02(d) and Section 8.02(e) of this Agreement, a Member who unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) shall be allocated items of income and gain (consisting of a pro rata portion of each item of income, including gross income, and gain for the Fiscal Period) in an amount and manner sufficient to eliminate any deficit balance in such Member’s Adjusted Capital Account as quickly as possible; provided that, an allocation pursuant to this Section 8.02(f) shall be made only if and to the extent that such Member would have deficit Adjusted

Capital Account balance after all other allocations provided for in this Article VIII have been tentatively made as if this Section 8.02(f) were not in this Agreement. This Section 8.02(f) is intended to constitute a qualified income offset under Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(g) In the event that any Member has a deficit balance in its Adjusted Capital Account at the end of any Fiscal Period, such Member shall be allocated items of Company gross income and gain in the amount of such deficit as quickly as possible; provided that an allocation pursuant to this Section 8.02(g) shall be made only if and to the extent that such Member would have a deficit balance in its Capital Account after all other allocations provided for in this Article VIII have been tentatively made as if Section 8.02(f) and this Section 8.02(g) were not in this Agreement.

(h) To the extent an adjustment to the adjusted tax basis of any Company properties pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts as the result of a distribution to any Member in complete liquidation of such Member’s Units, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be allocated to the Members in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(2) if such Section applies, or to the Member to whom such distribution was made if Treasury Regulation Section 1.704-1(b)(2)(iv)(m)(4) applies.

(i) If any Class B Units held by any holder of Class B Units are forfeited or redeemed by the Company, such holder shall be allocated items of loss and deduction in the Fiscal Period of such forfeiture or redemption in an amount equal to the portion of such holder’s Capital Account attributable to such forfeited Units reduced, but not below zero, by the amount of any redemption price paid by the Company for such Units.

(j) If, as a result of an exercise of a noncompensatory warrant or option to acquire an interest in the Company, a Capital Account reallocation is required under Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3) (as such Proposed Treasury Regulation may be amended or modified, including upon the issuance of temporary or final Treasury Regulations), the Company shall make corrective allocations pursuant to Proposed Treasury Regulation Section 1.704-1(b)(4)(x), as such Proposed Treasury Regulation may be amended or modified, including upon the issuance of temporary or final Treasury Regulations.

Section 8.03 Income Tax Allocations.

(a) All items of income, gain, loss and deduction for federal income tax purposes shall be allocated in the same manner as the corresponding item is allocated pursuant to Section 8.01 or Section 8.02, except as otherwise provided in this Section 8.03.

(b) In accordance with Code Section 704(c) and the applicable Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the Company shall, solely for tax purposes, be allocated among the Members so as

to take account of any variation between the adjusted basis of such property to the Company for Federal income tax purposes and its initial Book Value. In the event the Book Value of any property is adjusted pursuant to clause (b) or (d) of the definition of Book Value, subsequent allocations of income, gain, loss, and deduction with respect to such property shall take account of any variation between the adjusted basis of such property for Federal income tax purposes and its Book Value in the same manner as under Code Section 704(c) and the applicable Regulations thereunder. For purposes of the allocations pursuant to this Section 8.03, the Company shall elect the traditional allocation method described in Treasury Regulation Section 1.704-3(d) or such other allocation method as is determined by the Board.

Section 8.04 Other Allocation Rules.

(a) All items of income, gain, loss, deduction and credit allocable to an interest in the Company that may have been Transferred shall be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as the owner of such interest, without regard to the results of Company operations during any particular portion of that calendar year and without regard to whether cash distributions were made to the transferor or the transferee during that calendar year; provided, however, that this allocation must be made in accordance with a method permissible under Code Section 706 and the Treasury Regulations thereunder

(b) The Members’ proportionate shares of the “excess nonrecourse liabilities” of the Company, within the meaning of Treasury Regulation Section 1.752-3(a)(3), shall be allocated 87.5% to the holders of Class A Units in proportion to their respective Class A Unit Sharing Percentages and 12.5% to the holders of Class B Units in proportion to their respective Class B Unit Sharing Percentage, as applicable.

(a) First: 100% to the Class A Members in proportion to their respective Class A Unit Sharing Percentages until the aggregate distributions in respect of each Class A Unit pursuant to this Section 9.01(a) shall equal the aggregate amount of all Capital Contributions made to the Company in respect of such Class A Unit;

(b) Second: 98% to the Class A Members in proportion to their respective Class A Unit Sharing Percentages and 2% to the Class B Members in proportion to their respective Class B Unit Sharing Percentages, until such time as the aggregate amount of distributions in respect of each Class A Unit pursuant to this Section 9.01(b) shall equal an amount that when taking into account all prior IRR Cash Flows with respect to such Class A Unit would result in an eight percent (8%) IRR on all Capital Contributions in respect of such Class A Unit;

(c) Third: 90% to the Class A Members in proportion to their respective Class A Unit Sharing Percentages and 10% to the Class B Members in proportion to their respective Class B Unit Sharing Percentages, until such time as the aggregate amount of distributions in respect of each Class A Unit pursuant to this Section 9.01(c) shall equal the greater of (i) an amount that when taking into account all prior IRR Cash Flows with respect to such Class A Unit would result in a twenty-five percent (25%) IRR on all Capital Contributions in respect of such Class A Unit and (ii) an amount that when taking into account all prior IRR Cash Flows with respect to such Class A Unit would equal 3.0 times the aggregate amount of all Capital Contributions made to the Company in respect of such Class A Unit; and

(d) Thereafter: 87.5% to the Class A Members in proportion to their respective Class A Unit Sharing Percentages and 12.5% to the Class B Members in proportion to their respective Class B Unit Sharing Percentages.

Section 9.02 Distributions in Kind. No Member has any right to demand or receive a distribution from the Company in any form other than cash.

Section 9.03 Tax Distributions. Notwithstanding the foregoing distribution provisions of Section 9.01, to the extent funds are available therefor (as determined by the Board, after taking into account such reserves as the Board determines to be appropriate to accommodate the Company’s business plan, expected expenditures, contingencies and such other factors as the Board may consider in its sole discretion), each Member shall be entitled to receive cumulative cash distributions in an amount sufficient to enable such Member to discharge its cumulative U.S. federal, state and local tax liability (excluding interest and penalties) arising as a result of such Member’s interest in the Company, determined by assuming the applicability to such Member of the highest combined effective marginal federal, state and local income tax rate applicable to individuals residing in New York, New York at the time of such distributions taking into account the character of the income. In furtherance of and subject to the foregoing, to the extent the cumulative distributions otherwise paid or payable to a Member pursuant to Section 9.01 are insufficient to cover such tax liabilities, the Company shall make cash distributions (the “Tax Distributions”) in amounts that, when added to the cumulative cash distributions otherwise paid or payable, shall equal such tax liability. The amount of such tax liability shall be calculated taking into account (a) all cumulative Profits, income and gain allocated to such Member under this Agreement, including Profits, income and gain allocated in

prior Fiscal Years, but expressly excluding any Code Section 704(c) gain allocated to such Member hereunder, (b) the deductibility (to the extent allowed) of state and local income taxes for United States federal income tax purposes, (c) all cumulative Losses, deductions or other losses allocated to such Member under this Agreement, including Losses, deductions or other losses allocated in prior Fiscal Years, and (d) the character of the Profits, income, credits, Losses or deductions allocated to such Member. Tax Distributions made to a Member pursuant to this Section 9.03 shall be debited against such Member’s Capital Account and shall be treated as an advance distribution that will reduce on a dollar-for-dollar basis the amount of later distributions to such Member pursuant to Section 9.01 or Section 16.03(b). Notwithstanding anything contained herein to the contrary, the Company may not distribute any amount to a Member under this Agreement for any liability of the Member, whether tax, interest, or penalty, related to (i) the Member’s treating an item on its federal income tax return inconsistent with the treatment of the item on the Company’s annual information return, even if the Member complies with the notification of inconsistent treatment provisions of Code Section 6222(b) and (ii) the issuance of Class B Units to such Member, the forfeiture of Class B Units by such Member or another Member or the repurchase of Class B Units from such Member or another Member.

Section 9.04 Retained Distributions. Any distributions (except tax distributions pursuant to Section 9.03) with respect to Class B Units that have not “vested” in accordance with the provisions of Section 13.06(b) shall be retained by the Company until “vesting” occurs (the “Retained Distributions”). Retained Distributions shall be promptly distributed by the Company upon vesting of the relevant Class B Units. Retained Distributions that are in respect of unvested Class B Units that are forfeited to the Company pursuant to Section 13.06(c) of this Agreement and become Class B Company Units shall be reallocated among the Members in accordance with Section 9.01.

Section 10.01 Meetings. Annual meetings of Members may, but need not, be held. The annual meeting of Members may be held at such place and on such date as the Board may designate. Special meetings of the Members, for any purpose or purposes, unless otherwise prescribed by statute, may be called by the Board, or any Member or Members who hold in the aggregate a majority of the aggregate Class A Units.

Section 10.02 Place of Meetings. The Board may designate any place, either within or outside the State of Delaware, as the place of meeting for any meeting of the Members. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the Principal Office of the Company.

Section 10.03 Notice of Meetings. Written notice stating the place, day and hour of the meeting and the purpose or purposes for which the meeting is called shall be delivered not less than ten (10) nor more than sixty (60) days before the date of the meeting, either personally or by mail, by or at the direction of the Board or Person calling the meeting, to each Member entitled to vote at such meeting.

Section 10.04 Record Date. For the purpose of determining Members entitled to notice of or to vote at any meeting of Members or any adjournment thereof, or Members entitled to receive payment of any distribution, or in order to make a determination of Members for any other purpose, the date on which notice of the meeting is mailed or the date on which the resolution declaring such distribution or other determination is adopted, as the case may be, shall be the record date for such determination of Members.

Section 10.05 Quorum. Members holding at least a majority of all Class A Units represented in person or by proxy shall constitute a quorum at any meeting of Members. In the absence of a quorum at any such meeting, a majority of the Class A Units so represented may adjourn the meeting from time to time for a period not to exceed sixty (60) days without further notice. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed. The Members present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal during such meeting of that number of Class A Units whose absence would cause less than a quorum.

Section 10.06 Manner of Acting. The affirmative vote of a Class A Majority shall be the act of the Members, unless otherwise required by this Agreement.

Section 10.07 Proxies. At all meetings of Members, a Class A Member may vote in person or by proxy executed in writing by the Member or by a duly authorized attorney in fact. Such proxy shall be filed with the Board before or at the time of the meeting. No proxy shall be valid after eleven (11) months from the date of its execution, unless otherwise provided in the proxy. An electronic mail or similar transmission by a Class A Member, or a photographic, photostatic, facsimile or similar reproduction of an executed writing shall be regarded as executed by such Member for purposes of this Section 10.07. The chairman of the meeting shall decide all questions touching upon the qualification of voters, the validity of the proxies, and the acceptance or rejection of votes, unless an inspector or inspectors shall have been appointed by the chairman of the meeting, in which event such inspector or inspectors shall decide all such questions. A proxy shall be with full power of substitution and shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest. Should a proxy designate two (2) or more Persons to act as proxies, unless that instrument shall provide to the contrary, a majority or, if only two Persons are designated as proxies, then both, of such Persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all the powers of voting or giving consents thereby conferred, or if only one be present, then such powers may be exercised by that one.

Section 10.08 Action by Members Without a Meeting; Telephone Conference.

(a) Any action required or permitted to be taken at a meeting of Members may be taken without a meeting if the action is evidenced by one or more written consents describing the action to be taken by the Members that are signed by the Members whose consent is necessary to approve the action as required by this Agreement, the DLLCA or otherwise. Action taken under this Section 10.08 is effective when the requisite number of Members required to approve such action have signed the consent, unless the consent specifies a different effective date. The record date for determining Members entitled to take action without a

meeting is the date the first Member signs and delivers to the Company a written consent. An electronic mail or similar transmission by a Member, or a photographic, photostatic, facsimile or similar reproduction of a writing signed by a Member, shall be regarded as signed by the Member for purposes of this Section 10.08.

(b) Members may participate in and hold a meeting by means of conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear or otherwise communicate with 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 10.09 Waiver of Notice. When any notice is required to be given to any Member, a waiver thereof in writing signed by the Person entitled to such notice, whether before, at, or after the time stated therein, shall be equivalent to the giving of such notice.

Section 10.10 Conduct of Meetings. All meetings of the Members shall be presided over by the chairman of the meeting, who shall be a Manager or Officer designated by the Board. The chairman of any meeting of Members shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seem to him in order.

MANAGEMENT OF THE COMPANY

Section 11.01 Management.

(a) The business and affairs of the Company shall be managed by or under the direction of a board of managers (the “Board”), and, subject to the limitations set forth in this Agreement, the Board shall have full, exclusive and complete authority and discretion in the management and control of the administration, affairs and operations of the Company. Each member of the Board shall be a “Manager” of the Company as defined in Section 18-101(10) of the DLLCA. Notwithstanding anything contained herein to the contrary, a Manager shall not have any power or authority to act individually on behalf of the Company in his or her capacity as a Manager except for such power or authority as may be specifically conferred upon such Manager by this Agreement or by action of the Board.

(b) To the fullest extent permitted by the DLLCA, a person, in performing his or her duties and obligations as a Manager under this Agreement, shall (i) owe no fiduciary or similar duty or obligation whatsoever to the Company, any Member (other than the Member or class of Members designating such Manager) or the other Managers and (ii) be entitled to act or omit to act at the direction of the Member or class of Members that designated such person to serve on the Board, considering only such factors, including the separate interests of the designating Member or class of Members, as such Manager or Members choose to consider, and

any action of a Manager or failure to act, taken or omitted in good faith reliance on the foregoing provision shall not, as between the Company and the other Members, on the one hand, and the Manager or Member or class of Members designating such Manager, on the other hand, constitute a breach of any duty (including any fiduciary or other similar duty, to the extent that such exists under the DLLCA or any other applicable law, rule or regulation) on the part of such Manager, Members or class of Members.

(c) The Members (in their own capacities and on behalf of the Company) hereby: (i) agree that (A) the terms of Section 11.01(b), to the extent that it modifies or limits a duty or other obligation, if any, that a Manager may have to the Company or any other Member under the DLLCA or other applicable law, rule or regulation, are reasonable in form, scope and content; and (B) the terms of Section 11.01(b) shall control to the fullest extent possible if it is in conflict with a duty, if any, that a Manager may have to the Company or another Member, under the DLLCA or any other applicable law, rule or regulation; and (ii) waive to the fullest extent permitted by the DLLCA, any duty or other obligation, if any, that a Member may have to the Company or another Member, pursuant to the DLLCA or any other applicable law, rule or regulation, to the extent necessary to give effect to the terms of Section 11.01(b) above. The Members (in their own capacities and on behalf of the Company) acknowledge, affirm and agree that (i) the Class A Members would not have been willing to make an investment in the Company and no person designated by the Class A Members to serve on the Board would be willing to serve, in the absence of Section 11.01(b) above, and (ii) they have reviewed and understand the provisions of Sections 18-1101(b) and (c) of the DLLCA.

Section 11.02 Board.

(a) Composition. The Board shall initially be composed of seven Managers. Subject to Section 11.05, four Managers will be designated from time to time by the SW Representative (the “SW Designees”); provided, however, that if at any time the aggregate Class A Unit Sharing Percentage of the SW Group is less than 32% but equal to or greater than 5%, then two SW Designees shall be removed and the SW Representative shall only be entitled to designate two Managers; provided further that if at any time the aggregate Class A Unit Sharing Percentage of the SW Group is less than 5%, the remaining SW Designee shall be removed and the SW Representative shall no longer be entitled to designate a Manager. Two Managers will be designated from time to time by the DLJ VCOC Fund (the “DLJ Designees”); provided that if at any time the aggregate Class A Unit Sharing Percentage of the DLJ Group is less than 20% but equal to or greater than 5%, then one DLJ Designee shall be removed and the DLJ VCOC Fund shall only be entitled to designate one Manager; provided further that if at any time the aggregate Class A Unit Sharing Percentage of the DLJ Group is less than 5%, the remaining DLJ Designee shall be removed and the DLJ VCOC Fund shall no longer be entitled to designate a Manager. One Manager will be designated from time to time by a Class B Majority (the “Class B Designee”). The initial SW Designees, DLJ Designees and Class B Designee are set forth on Exhibit C.

(b) Meetings. The Board shall meet at least quarterly at such place as determined by the Board. Special meetings of the Board, to be held at such place as shall be determined by the Board, shall be called at the direction of any two Managers, upon reasonable advance notice, but in any event upon not less than 48 hours’ prior written notice, which period

must include at least one Business Day, to all Managers. Attendance of a Manager at a meeting shall constitute a waiver of notice of such meeting, except where a Manager attends a meeting for the express purpose of objecting to the transaction of any business on the ground that such meeting is not properly called or convened.

(c) Quorum; Voting. The presence of at least five of the Managers shall be necessary to constitute a quorum at any meeting of the Board. Each Manager shall have one vote and, unless otherwise expressly stated in this Agreement, all actions requiring the consent or approval of the Board shall require the consent of a majority of the Board. Notwithstanding the foregoing, the SW Designees and DLJ Designees shall be entitled to cast in the aggregate a number of votes at a meeting equal to the number of Managers the SW Group or DLJ Group, as applicable, is entitled to designate if (i) any SW Designee or DLJ Designee is not present at such meeting (and such absent SW Designee or DLJ Designee shall be deemed to have given a proxy to vote at such meeting to the other SW Designees or DLJ Designees, as applicable) or (ii) if there are any vacancies on the Board which the SW Group or DLJ Group is entitled to fill with its designees (for example, if SW is entitled to designate four Managers and has designated only two Managers, then those two Managers or either of them may cast a total of four votes on matters presented to the Board). A Manager entitled to cast multiple votes in accordance with the foregoing shall, for quorum purposes, count as a number of Managers equal to such number of votes.

(d) Action by Written Consent. Any action required or permitted to be taken at a meeting of the Board may be taken without a meeting if the action is evidenced by one or more written consents describing the action to be taken by the Board that are signed by at least five Managers. Action taken under this Section 11.02(d) is effective when the requisite number of Managers required to approve such action have signed the consent, unless the consent specifies a different effective date. An electronic mail or similar transmission by a Manager, or a photographic, photostatic, facsimile or similar reproduction of a writing signed by a Manager, shall be regarded as signed by the Manager for purposes of this Section 11.02(d). The Board may participate in and hold a meeting by means of conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear or otherwise communicate with 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.

(e) Vacancies. If any SW Designee shall resign or be removed or be unable to serve for any reason as a Manager of the Company, subject to Section 11.05, the SW Representative shall designate a replacement SW Designee. The SW Representative may remove and replace any SW Designee at any time with or without cause. If any DLJ Designee shall resign or be removed or be unable to serve for any reason as a Manager of the Company, subject to Section 11.05, the DLJ Representative shall designate a replacement DLJ Designee. The DLJ Representative may remove and replace any DLJ Designee at any time with or without cause. If the Class B Designee shall resign or be removed or unable to serve for any reason as a Manager of the Company, subject to Section 11.05, the Class B Majority shall designate a replacement Class B Designee. A Class B Majority may remove and replace the Class B Designee at any time with or without cause. Except as provided in Section 11.02(a), no DLJ

Designee shall be removed without the prior written consent of the DLJ Representative. The Class B Designee shall not be removed without the prior written consent of the Class B Majority.

(f) Costs and Expenses. The Company will pay all reasonable out-of-pocket expenses incurred by the Managers in connection with their participation in meetings of the Board (and committees thereof) and attending to the business of the Company.

(g) If at any time the aggregate Class A Unit Sharing Percentage of the DLJ Group or the SW Group, as the case may be, is less than 5%, the DLJ VCOC Fund or the SW VCOC Fund, as applicable, shall have the right to appoint one representative to attend and fully participate in each meeting of the Board as a non-voting observer (an “Observer”). The Company will give the DLJ VCOC Fund and/or the SW VCOC Fund, as applicable, (i) written notice of each meeting of the Board at the same time and in the same manner as notice is given to the Managers and (ii) a copy of all written materials and other information (including, without limitation, copies of minutes of meetings) given to Managers in connection with such meetings at the same time such materials and information are given to such Managers. If the Board proposes to take any action by written consent in lieu of a meeting of the Board, the Company shall give written notice thereof to the DLJ VCOC Fund and/or the SW VCOC Fund, as applicable, promptly following the effective date of such consent describing in reasonable detail the nature and substance of such action. Notwithstanding any other right granted under this Section 11.02(g), the Company reserves the right to exclude any Observer from access to any material or meeting or portion thereof if the Company believes on the advice of counsel that such exclusion is reasonably necessary to preserve the attorney-client privilege. This Section 11.02(g) shall cease to apply during any period in which the DLJ VCOC Fund or the SW VCOC Fund, as applicable, ceases to own any Units.

Section 11.03 Request for Sale of Company by the SW Group.

(a) Subject to Section 11.03(e), notwithstanding anything to the contrary contained in this Agreement, at any time after the date of this Agreement, the SW Group may give written notice to the Company and the Members requiring a sale of the Company (an “Approved Sale”). An Approved Sale may be effected pursuant to a securities disposition (by Unit sale, merger, consolidation or otherwise) or disposition of the assets of the Company, as determined by the SW Group in its sole discretion. Each Member hereby agrees to vote (to the extent any such vote is required) all of its Units in favor of an Approved Sale upon the written request of the SW Group. If the Approved Sale is structured as a (i) merger, consolidation or sale of assets, each Member shall waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger, consolidation or sale of assets or (ii) sale of Units, each Member shall agree to sell all of his, her or its Units or rights to acquire Units on the terms and conditions approved by the SW Group. Each Member shall take all necessary or desirable actions in its capacity as a Member in connection with the consummation of the Approved Sale as may be reasonably requested by the SW Group; provided, that, no Member shall be required to assume or incur any liability in excess of the amount to be distributed to such Member or assume or incur liabilities in a disproportionate amount compared to the amounts to be distributed to and liabilities to be assumed or incurred by the Class A Members in connection with the Approved Sale.

(b) In any Approved Sale all of the Units shall be converted into or entitled to receive, as applicable, a proportionate amount of the aggregate consideration to be paid by the acquiring party, with such proportions to be determined by applying Section 9.01 to a Distributable Property amount equal to the sum of (a) the cash included in such consideration plus (b) the Fair Market Value of any non-cash property included in such consideration.

(c) If the Approved Sale is a transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such transaction (including a merger, consolidation or other reorganization), the Members that do not qualify as Accredited Investors (without regard to Rule 501(a)(4)) may be required, at the request of the SW Group, to (i) appoint a purchaser representative (as such term is defined in Rule 501) (the “Purchaser Representative”) or (ii) accept cash in lieu of any securities such non-Accredited Investor would otherwise receive in an amount equal to the Fair Market Value of such securities. If any Member appoints the Purchaser Representative as its purchaser representative, the Company will pay the fees of such purchaser representative, but if any Member declines to appoint the Purchaser Representative, such Member will, if required, appoint another purchaser representative, and such Member will be responsible for the fees of the purchaser representative so appointed.

(d) Members shall bear their pro rata share (based upon the allocation set forth in Section 11.03(b) by treating the costs as reducing the amount of Distributable Property) of the costs of any sale of Units pursuant to an Approved Sale to the extent such costs are incurred for the benefit of all Members and are not otherwise paid by the Company or the acquiring party. Notwithstanding anything herein to the contrary, for purposes of this Section 11.03(d), reasonable third party costs incurred by the Class A Members and Class B Members in exercising reasonable efforts to take all actions in connection with the consummation of an Approved Sale in accordance with Section 11.03(a) shall be deemed to be for the benefit of all Members. Costs incurred by Members on their own behalf will not be considered costs of the transaction hereunder.

(e) The SW Group shall not be entitled to exercise its rights under this Section 11.03 at any time that the aggregate Class A Unit Sharing Percentage of the SW Group is less than 50%.

Section 11.04 Conversion to a Corporation; Public Offering.

(a) The Board may cause the conversion of the Company, or any portion thereof, into a corporation, including by (i) the transfer of all of the assets of the Company, subject to the Company’s liabilities, or the transfer of any portion of such assets and liabilities, to one or more corporations in exchange for shares of any such corporations and the subsequent distribution of such shares, at such time as the Board may determine, to the Members, (ii) conversion of the Company into a corporation pursuant to Section 18-216 of the DLLCA (or any successor section thereto) or (iii) Transfer by each Member of Units held by such Member to one or more corporations in exchange for shares of any such corporations (including by merger of the Company into a corporation) (each of (i), (ii) and (iii), a “Reorganization”). Each Member shall take all actions in its capacity as a Member reasonably requested by the Board in connection with the consummation of such Reorganization, including without limitation consenting to, voting for

and waiving any dissenters rights, appraisal rights or similar rights and participating in any exchange or other transaction required in connection with such Reorganization. The Company shall pay any and all reasonable organizational, legal and accounting expenses and filing fees incurred by the Company, the Class A Members and the Class B Members in connection with such Reorganization.

(b) In connection with any Reorganization as described in Section 11.04(a)(i), the shares (which will be valued at their Fair Market Value) received will be distributed in accordance with Section 9.01.

(c) In connection with any Reorganization as described in Section 11.04(a)(ii) above, each Unit shall be converted into a proportionate amount of the common stock of the resulting corporation, with such proportion to be determined by applying Section 9.01 to the total number of shares of common stock to be distributed upon conversion (which shares will be valued at their Fair Market Value).

If securities other than or in addition to common stock are issued to Unit holders by the resulting corporation in such Reorganization, each class or series of securities shall be allocated among the holders of Units as provided in this Section 11.04(c).

(d) In connection with any such Reorganization as described in Section 11.04(a)(iii) above, each class of Units shall be converted into the right to receive the same series or class of securities of the corporation and such securities shall be allocated among the Class A Units and Class B Units, and among the holders of Class A Units and Class B Units, in the same manner as shares of common stock are allocated in the event of a Reorganization under Section 11.04(a)(ii) as provided in Section 11.04(c).

(e) In connection with any Reorganization as provided in Section 11.04(a)(ii) or Section 11.04(a)(iii) above, (i) each holder of a particular class of Units shall receive the same form of securities and the same amount of securities per Unit of such class as the other holders of such class of Units and if any holders of a class of Units are given an option as to the form and amount of securities to be received, each holder of such class of Units shall be given the same option and (ii) each holder of Units agrees to the Transfer of its Units in accordance with the terms of conversion or exchange, as applicable, as provided by the Board. Each holder of Units further agrees that as of the effective date of such conversion or exchange any Unit outstanding thereafter that shall not have been tendered for conversion or exchange shall represent only the right to receive a certificate representing the number of shares of any such corporations as provided in the terms of such conversion or exchange.

(f) If the Board approves an initial Public Offering, each Member shall take all necessary or desirable actions in its capacity as a Member reasonably requested by the Board in connection with the consummation of such Public Offering, including, without limitation, compliance with the requirements of all laws and regulatory bodies that are applicable or that have jurisdiction over such Public Offering. If such Public Offering is an underwritten offering:

(i) and the managing underwriters advise the Company in writing that in their opinion the Company’s capital structure would adversely affect the marketability

of the offering, each Member shall consent to and vote for a recapitalization, reorganization or exchange (each, a “Recapitalization”) of any class of the Company’s equity securities into securities that the managing underwriters and the Board find acceptable and shall take all necessary and desirable actions in its capacity as a Member in connection with the consummation of such Recapitalization; provided that each holder of a class of Units shall receive the same type of security with the same value per Unit as the other holders of such class of Units (other than differences based upon differences in the amount of yield accrued on such Units since their respective dates of issuance) and shall be subject to the same restrictions on lock-up and transferability unless otherwise agreed to by the Board or the managing underwriters; and

(ii) if requested by the managing underwriters, each of the Members shall execute customary lock-up agreements with respect to their Units and/or any securities received by them in any attendant Reorganization or Recapitalization.

(g) Prior to the consummation of a Public Offering, the Company (or its successor pursuant to a Reorganization) shall enter into a registration rights agreement with the Members containing customary terms and conditions, in form and substance reasonably satisfactory to SW and the DLJ Representative.

(h) The provisions of this Section 11.04 are not intended to and shall not in any way diminish the power and authority of the Board as set forth in Section 11.01 or any other provision of this Agreement.

Section 11.05 VCOC Fund Management Rights.

(a) In the event that any member of the SW Group is, or in the event that SW transfers any Class A Units to, a fund that is required to satisfy the criteria for being a “venture capital operating company” (as defined by the regulations issued by the United States Department of Labor at Section 2510.3-101 of Part 2510 of Chapter XXV, Title 29 of the United States Code of Federal Regulations) (the “SW VCOC Fund”), and the aggregate Class A Unit Sharing Percentage of the SW Group is at least 5%, then such SW VCOC Fund shall be entitled to the rights and privileges associated with such Class A Units and shall be entitled to appoint at least one SW Designee to the Board (the “VCOC Manager”). In the event that a DLJ Member is, or in the event that a DLJ Member transfers any Class A Units to, a fund that is required to satisfy the criteria for being a “venture capital operating company” (as defined by the regulations issued by the United States Department of Labor at Section 2510.3-101 of Part 2510 of Chapter XXV, Title 29 of the United States Code of Federal Regulations) (including DLJ Merchant Banking Partners III, L.P., the “DLJ VCOC Fund”), and the aggregate Class A Unit Sharing Percentage of the DLJ Group is at least 5%, then such DLJ VCOC Fund shall be entitled to the rights and privileges provided in Section 11.02(a) to appoint at least one DLJ Designee to the Board (the “DLJ VCOC Manager”).

(b) Each of the Members and the Company agrees to take any and all actions reasonably necessary and appropriate (whether by vote or consent or otherwise) to cause the election or appointment of each VCOC Manager to the Board. In addition, in the event of the establishment of any committee of the Board, each VCOC Fund shall have the right to have its

VCOC Manager also appointed to such committee, unless prohibited by applicable law or the policy of any self-regulatory organization to which the Company is subject.

(c) The Board and the Members agree not to amend this Agreement to modify or eliminate the right of a VCOC Fund to appoint at least one Manager to the Board pursuant to Section 11.05(a) without the written consent of such VCOC Fund, whose consent may be given or withheld in such VCOC Fund’s sole discretion.

(d) Any VCOC Manager may only be removed by the VCOC Fund that appointed such VCOC Manager (and such removals may be undertaken by such VCOC Fund at any time for any reason, with or without cause, or for no reason).

(e) Upon the resignation or removal hereunder of a VCOC Manager, a successor VCOC Manager will be nominated by the VCOC Fund that appointed such VCOC Manager and such nominee will become the successor VCOC Manager.

(f) If the Company shall at any time establish a majority-owned subsidiary, the Company shall use its commercially reasonable efforts to cause each VCOC Fund to have the rights with respect to the appointment of an observer to the board of directors (or similar governing body) of such subsidiary that are substantially the same, as nearly as practicable, to the rights of such VCOC Fund contained in this Section 11.05.

Section 11.06 Access to Information by the VCOC Funds.

(a) Each VCOC Fund has the right to request and obtain from the Company the delivery of copies of the books and records of the Company (and each of its direct or indirect subsidiaries), including financial data (including projections) and operating data covering the business operations and financial performance of the Company (and its direct or indirect subsidiaries).

(b) Each VCOC Fund will have the reasonable right (i) to consult from time to time with the Officers, the Board, and the supervisors or independent accountants of the Company (and its direct or indirect subsidiaries) at their respective place of business regarding operating and financial matters, and (ii) to visit and inspect any of the properties of the Company (and any of its direct or indirect subsidiaries), so long as the exercise of such rights does not interfere with the operations or business of the Company.

(c) Subject to Section 11.06(d), any provision of this Section 11.06 may be amended by the Company and a VCOC Fund for purposes of preserving the qualification of a VCOC Fund as a “venture capital operating company” (as defined by the regulations issued by the United States Department of Labor at Section 2510.3-101 of Part 2510 of Chapter XXV, Title 29 of the United States Code of Federal Regulations) (a “VCOC”), or otherwise to ensure that the assets of a VCOC Fund are not considered “plan assets”, for purposes of ERISA and the regulations thereunder and interpretations thereof promulgated by the Department of Labor, as in effect from time to time, of the benefit plan investors in a VCOC Fund, by an agreement in writing which indicates that it is intended to be an amendment, executed by the Company and a VCOC Fund or its nominee, and no consent or agreement of any other party hereto will be required.

(d) The Company agrees that if a VCOC Fund notifies the Company in writing that the provisions of this Section 11.06 should be amended to preserve the qualification of a VCOC Fund as a VCOC, or otherwise to ensure that the assets of a VCOC Fund are not considered “plan assets” for purposes of ERISA of the benefit plan investors in a VCOC Fund, the Company will consent to proposed amendments that provide such VCOC Fund with such other rights which such VCOC Fund and the Company agree are reasonably necessary under applicable legal authority to qualify such VCOC Fund’s investment in the Company as a “venture capital investment” (as defined in the regulations issued by the United States Department of Labor at Section 2510.3-101 of Part 2510 of Chapter XXV, Title 29 of the United States Code of Federal Regulations).

Section 11.07 Officers. The Board may appoint such officers of the Company as the Board may deem necessary or advisable to manage the day-to-day business affairs of the Company (collectively, the “Officers”). To the extent authorized by the Board, any Officer may act on behalf of, bind and execute and deliver documents in the name and on behalf of the Company. Unless otherwise provided by the Board, the appointment of an Officer shall constitute the delegation to such Officer of the authority and duties that are normally associated with that office, subject to any specific delegation of authority and duties made to such Officer. The initial Officers of the Company are set forth on Exhibit C hereto. The Executive Management Team and any Officers of the Company are required to promptly notify the Board of any material occurrences or incidents relating to the Company’s business or operations. 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 under the laws of the State of Delaware.

ARTICLE XII

INDEMNIFICATION

Section 12.01 Power to Indemnify in Actions, Suits or Proceedings. Subject to Section 12.03, the Company shall indemnify any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that he is or was a Member, Officer or Manager of the Company, or is or was serving at the request of the Company as a member, officer, manager or director of another limited liability company, corporation, partnership, joint venture, trust or other enterprise (each, an “Indemnitee”), against any and all losses, claims, expenses (including attorneys’ fees), costs, liabilities, damages, judgments, fines

and amounts paid in settlement actually and reasonably incurred by such Person in connection with such action, suit or proceeding; provided, that such Person shall not be indemnified by the Company for any acts or omissions by such Person that constitute bad faith, fraud, willful or intentional misconduct, criminal wrongdoing or gross negligence or, in the case of an Officer, breach of such Person’s duties pursuant to Section 11.07. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that such Person’s act or omission was not in accordance with the previous standard unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that such Person’s act or omission was not in accordance with the previous standard. Any indemnification provided hereunder will be satisfied solely out of the assets of the Company, as an expense of the Company. No Member will be subject to personal liability by reason of these indemnification provisions.

Section 12.02 Authorization of Indemnification. Any indemnification under this Article XII (unless ordered by a court) shall be made by the Company only as authorized in the specific case upon a determination that indemnification of the Indemnitee is proper in the circumstances because such Person has met the applicable standard of conduct set forth in Section 12.01. Such determination shall be made by a vote, which shall not be unreasonably withheld, of a majority in number of the members of the Board (excluding any such Person who is seeking indemnification at issue). To the extent that an Indemnitee has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 12.01, or in defense of any claim, issue or matter therein, such Person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such Person in connection therewith, without the necessity of authorization in the specific case.

Section 12.03 Expenses Payable in Advance. Expenses incurred by an Indemnitee in defending or investigating a threatened or pending action, suit or proceeding for which indemnification may be available under Section 12.01 shall be paid by the Company in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Person is not entitled to be indemnified by the Company as authorized by this Article XII; provided that the Company shall not be obligated to pay in advance any such expenses of an Indemnitee in connection with a proceeding (or part thereof) initiated by such Person unless such proceeding (or part thereof) was authorized or consented to by the Board.

Section 12.04 Nonexclusivity of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by or granted pursuant to this Article XII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any agreement, contract, vote of Members or Managers or pursuant to the direction (howsoever embodied) of any court of competent jurisdiction or otherwise, both as to action in such Person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Company that indemnification of the Persons specified in Section 12.01 shall be made to the fullest extent permitted by law. The provisions of this Article XII shall not be deemed to preclude the indemnification of any Person who is not specified in Section 12.01, but whom the Company has the power or obligation to indemnify under the provisions of the DLLCA or otherwise.

Section 12.05 Survival of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article XII shall, unless otherwise provided when authorized or ratified, continue as to a Person who has ceased to be an Indemnitee and shall inure to the benefit of the heirs, executors and administrators of such a Person. Any modification, amendment or repeal of this Article XII shall be prospective only and shall not in any way affect the limitations on liability of the Indemnitees, or terminate, reduce or impair the right of any past, present or future Indemnitees, under and in accordance with this Article XII as in effect immediately prior to such amendment, modification or repeal, with respect to claims arising from or relating to matters occurring prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 12.06 Limitation on Indemnification. Notwithstanding anything contained in this Article XII to the contrary, except for proceedings to enforce rights to indemnification, the Company shall not be obligated to indemnify any Indemnitee in connection with a proceeding (or part thereof) initiated by such Person unless such proceeding (or part thereof) was authorized or consented to by the Board.

Section 12.07 Indemnification of Employees and Agents. The Company may, to the extent authorized from time to time by the Board, provide rights to indemnification and the advancement of expenses to employees and agents of the Company similar to those conferred in this Article XII to Indemnitees.

Section 12.08 Severability. The provisions of this Article XII are intended to comply with the DLLCA. To the extent that any provision of this Article XII authorizes or requires indemnification or the advancement of expenses contrary to the DLLCA or the Certificate, the Company’s power to indemnify or advance expenses under such provision shall be limited to that permitted by the DLLCA and the Certificate and any limitation required by the DLLCA or the Certificate shall not affect the validity of any other provision of this Article XII.

Section 12.09 Exculpation. No Indemnitee will be liable to the Company or to any Member for any act or failure to act if he, she or it acted in good faith. The Members, Officers and Managers of the Company will not be liable to the Company or to any Member for such Person’s good faith reliance on the provisions of this Agreement. The Board may exercise any of the powers granted to it by this Agreement and perform its duties either directly or through its agents and it shall not be responsible for any misconduct or negligence on the part of any such agent appointed by it in good faith.

Section 12.10 Confidentiality. Each Member agrees that all non-public information received from or otherwise relating to, the Company, the Investor Group, or any third party who has entrusted the Company with confidential information with the expectation that such information will be kept confidential, is confidential and will not be (i) disclosed or otherwise released to any other Person (other than another party hereto for a valid business purpose) or (ii) used for anything other than as necessary and appropriate in carrying out the business of the Company. The obligations of the parties hereunder do not preclude members of the Investor Group from disclosing information to their respective beneficial owners or representatives or as they may reasonably deem to be appropriate in connection with fundraising efforts. The restrictions set forth herein do not apply to (i) information that is or becomes generally available

to the public without breach of this Section 12.10 or any Employment Agreement or other agreement between such Member and the Company or (ii) any disclosures required by applicable law, so long as (x) the Person subject to such disclosure obligations provides prior written notice (to the extent reasonably practicable) to the Company stating the basis upon which the disclosure is asserted to be required, and (y) the Person subject to such disclosure obligations takes all reasonable steps to oppose or mitigate any such disclosure, provided that the Company shall reimburse such person for all reasonable expenses related to such steps taken to oppose or mitigate any such disclosure.

Section 12.11 Non-Disparagement. Each Class A Member, each Class B Member and each member of the Executive Management Team agrees that, in communications with Persons other than the Members and the Company (and its and their respective Affiliates, employees, members and partners or employees of Affiliates of Members or the Company), he, she or it shall not knowingly and intentionally disparage the Company, its subsidiaries, each other Member (in its capacity as a Member) or the Executive Management Team. Under no circumstances shall any Class A Member, Class B Member or member of the Executive Management Team, in communications with Persons other than the Members and the Company (and its and their respective Affiliates, employees, members and partners or employees of Affiliates of Members or the Company), knowingly and intentionally disparage any business practice, policy, statement, valuation or report that is made, conducted or published by the Company, any other Member (and their Affiliates, members and partners) or the Executive Management Team. Notwithstanding the foregoing, this Section 12.11 shall not be construed to prohibit or restrain any communication or other statements made, directly or indirectly, in communications exclusively between or among any of the Members, the Company, any of its or their respective Affiliates, members, partners, directors, employees, attorneys, auditors, advisors or other representatives to the extent such communications or statements are made in the ordinary course of business or any communications or statements required by applicable law or listing application of any securities exchange. The obligations of each Class A Member, Class B Member and member of the Executive Management Team under this Section 12.11 shall continue after the date such Person ceases to be a Member until the first anniversary of the Member’s cessation as a Member of the Company.

Section 12.12 Fund Indemnitors. The Company hereby acknowledges that certain Indemnitees that are members of the Investor Group (the “Fund Indemnitees”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by certain of their affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to the Fund Indemnitees are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the Fund Indemnitees is secondary), (ii) that it shall be required to advance the full amount of expenses incurred by the Fund Indemnitees and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement (or any other agreement between the Company and the applicable Fund Indemnitee), without regard to any rights the Fund Indemnitees may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund

Indemnitors on behalf of a Fund Indemnitee with respect to any claim for which such Fund Indemnitee has sought indemnification from the Company shall affect the foregoing and the applicable Fund Indemnitor shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Fund Indemnitee against the Company. The Company and Fund Indemnitees agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 12.12.

ARTICLE XIII

TRANSFER OF UNITS

Section 13.01 Drag Along Rights.

(a) Applicability. Subject to Section 13.01(e), in connection with any Transfer by SW (a “Selling Member”) of Units representing more than 50% of the Class A Units then held by SW (a “Significant Sale”), the Selling Member shall have the right to require each non-selling Member (each, a “Co-Seller”) to Transfer, and each Co-Seller shall be required to Transfer, the same portion as SW, which portion shall equal the number of Units of each Class held by each Co-Seller multiplied by a fraction the numerator of which is equal to the number of Class A Units being transferred by SW in the Significant Sale and the denominator of which is equal to the total number of Class A Units held by SW immediately prior to the Significant Sale, such Units to be Transferred free and clear of all Liens, provided, however, that if all Co-Sellers are not required by the Selling Member to Transfer all of their Units in any Significant Sale, then any Units required to be Transferred by the Co-Sellers pursuant to such Significant Sale shall be allocated pro rata among the Co-Sellers holding each class or series of Units included in such Significant Sale based on the relative Membership Interest of such Co-Sellers in such class or series.

(b) All Units Transferred by Members pursuant to this Section 13.01 shall be treated identically with the Units being sold by the Selling Member in all respects; provided, however, that (i) the aggregate consideration to be paid shall be allocated as provided in Section 13.01(c) and (ii) such Co-Seller shall not be required to assume or incur any liability in excess of the proceeds to be distributed to such Co-Seller in connection with such Transfer.

(c) In any Significant Sale in which Co-Sellers participate, all Units held by Members participating in such Significant Sale shall be allocated a proportionate amount of the aggregate consideration to be paid by the acquiring party, with such proportions to be determined based on the sum of (A) the cash included in such consideration and (B) the Fair Market Value of any non-cash property included in such consideration, multiplied by a fraction, the numerator of which is the amount that would be distributable to such Units by applying Section 9.01 to a Distributable Property amount equal to the Significant Sale Value and the denominator of which is the Significant Sale Value.

(d) Notice of Significant Sale. The Selling Member shall give the Board written notice of a proposed Significant Sale as soon as practicable after the terms of such sale are initially agreed upon (i.e. upon the execution of a letter of intent or term sheet), regardless of whether such agreement is binding, non-binding, oral or written. The Selling Member shall give

each Co-Seller at least ten (10) days prior written notice of any Significant Sale as to which the Selling Member intends to exercise its rights under this Section 13.01. If a Selling Member elects to exercise its rights under this Section 13.01, each Co-Seller shall take such actions in its capacity as a Member as may be reasonably required and otherwise cooperate in good faith with the Selling Member in connection with consummating the Significant Sale (including, without limitation, the voting of any Units to approve such Significant Sale). At the closing of such Significant Sale, each Co-Seller shall deliver any certificates for all Units to be sold by such Co-Seller, duly endorsed for transfer to the purchaser against payment of the appropriate purchase price.

(e) SW shall not be entitled to exercise its rights under this Section 13.01 at any time that the aggregate Class A Unit Sharing Percentage of SW is less than 50%.

Section 13.02 Tag Along Rights.

(a) Subject to Section 13.02(c), if SW desires to effect a Transfer of any Units (a “Tag Sale”) and it does not elect to exercise its rights under Section 13.01 hereof to require each Co-Seller to Transfer all of their Units or a portion of their Units, then at least ten (10) Business Days prior to the closing of such Tag Sale, SW shall make a written offer (the “Participation Offer”) to each Co-Seller holding Class A Units to include in the proposed Tag Sale a portion of each Co-Seller’s Class A Units that represents the same percentage of such Co-Seller’s total number of Class A Units as the Class A Units being sold by SW represents of SW’s total number of Class A Units; provided, however, that, if the consideration to be received by SW includes any securities, then, unless SW and the transferee both reasonably determine in good faith that an exemption is otherwise available under the Securities Act and all applicable state securities laws for such transaction, each Co-Seller that does not qualify as an Accredited Investor (without regard to Rule 501(a)(4)) may be required, at the request of the SW Group, to (i) appoint a Purchaser Representative in accordance with the terms of Section 11.03(c) in order to participate in such Transfer or (ii) accept cash in lieu of any securities such non-Accredited Investor would otherwise receive in an amount equal to the Fair Market Value of such securities. The Class A Units of any Co-Seller sold in any Tag Sale shall entitle such Co-Seller to receive the amount which such Co-Seller would receive if Section 9.01 of this Agreement were applied to the Tag Sale Value for a particular Tag Sale, and, as a result of such application, amounts would be distributed to the holders of Units pursuant to Section 9.01 of this Agreement.

(b) The Participation Offer shall describe the terms and conditions of the proposed Tag Sale (including the number of Units to be sold) and shall be conditioned upon (i) the consummation of the transactions contemplated in the Participation Offer with the transferee named therein, (ii) each Co-Seller’s execution and delivery of all agreements and other documents as SW is required to execute and deliver in connection with such Tag Sale, (iii) SW and each Co-Seller making such representations, warranties and covenants (including related indemnity provisions) and entering into such definitive agreements as are customary for transactions of the nature of the proposed Tag Sale; provided that (A) any such indemnification or similar obligations will be apportioned pro rata among SW and the Co-Sellers (based on the aggregate consideration to be received in respect of its Units included in the Tag Sale), other than with respect to representations and indemnities concerning SW’s and each Co-Seller’s title to its Class A Units and authority, power and right to enter into and consummate the Transfer

without contravention of any law or agreement, which shall be given by SW and each Co-Seller solely with respect to itself and on a several basis and (B) no Member in its capacity as such shall be required to provide representations or warranties that are broader than those provided by SW, (iv) each Co-Seller benefiting from all of the same provisions of the definitive agreements as SW and being required to bear its proportionate share of any escrows, holdbacks, earnouts and adjustments in purchase price and (v) no Co-Seller being required to assume or incur any liability in excess of the proceeds to be distributed to such Co-Seller in connection with such Tag Sale. If any Co-Seller shall accept the Participation Offer by written notice to SW within five (5) Business Days after the date on which such Co-Seller receives the Participation Offer, SW shall reduce, to the extent necessary, the number of Class A Units it otherwise would have sold in the proposed Transfer so as to permit those Co-Sellers who have accepted the Participation Offer to sell the percentage of their Units that they are entitled to sell under Section 13.02(a) and SW and such Co-Sellers shall Transfer the number of Units specified in the Participation Offer to the proposed transferee in accordance with the terms of such Transfer as set forth in the Participation Offer.

(c) Notwithstanding anything in the foregoing to the contrary, if Section 9.01 were applied to a Distributable Property amount equal to the Tag Sale Value for a particular Tag Sale, and, as a result of such application, amounts would be distributed to the holders of Class B Units pursuant to Section 9.01 (such amount that would be distributed pursuant to Section 9.01 with respect to all of the Class B Units, the “Class B Tag Sale Value”), then holders of Class B Units may participate in any Tag Sale with respect to such Class B Units in accordance with this Section 13.02(c). In the event any holder of Class B Units shall elect to transfer its applicable Units in connection with any Participation Offer, for purposes of Section 13.02(a), such holder of Class B Units shall be entitled to include a portion of such holder’s Class B Units that represents the same percentage of such holder’s total Class B Units as the Class A Units being sold by SW represents of SW’s total number of Class A Units (provided that the proviso in Section 13.02(a) shall apply), and Sections 13.02(a) and 13.02(b) shall apply to the holder of the Class B Units, with such holder being a “Co-Seller.” The holder of Class B Units shall be entitled to receive, in exchange for the Transfer of such portion of its Class B Units in the Tag Sale, an amount equal to its proportionate share of the Class B Tag Sale Value based on a fraction, the numerator of which is equal to the number of Class B Units being sold by such Class B Member in the Tag Sale and the denominator of which is equal to the total number of Class B Units outstanding at the time of the Tag Sale.

Section 13.03 Certain Events Not Deemed Transfers. In no event shall any exchange, reclassification, or other conversion of Units into any cash, securities, or other property pursuant to a merger or consolidation of the Company with, or any sale or transfer by the Company of all or substantially all its assets to, any Person constitute a Significant Sale or Tag Sale by the SW Group for purposes of Section 13.01 or Section 13.02. In addition, Section 13.01 and Section 13.02 hereof shall not apply to any Transfer, sale or disposition of Units solely among investment vehicles organized and controlled by the SW Group (excluding portfolio companies of funds affiliated with the SW Group).

Section 13.04 Transfer and Exchange. When Units are presented to the Company with a request to register the Transfer of such Units or to exchange such Units for Units of other authorized denominations, the Company shall register the Transfer or make the exchange as

requested if the requirements of this Agreement for such transaction are met; provided, however, that the Units surrendered for Transfer or exchange shall be duly endorsed or accompanied by a written instrument of Transfer in form satisfactory to the Company, duly executed by the holder thereof or its attorney and duly authorized in writing. No service charge shall be made for any registration of Transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

Section 13.05 Replacement Securities. If a mutilated Unit is surrendered to the Company or if the Member claims and submits an affidavit or other evidence, satisfactory to the Company, to the effect that the Unit has been lost, destroyed or wrongfully taken, the Company shall issue a replacement Unit if the Company’s requirements are met. If required by the Company, such Member must provide an indemnity bond, or other form of indemnity, sufficient in the judgment of the Company to protect the Company against any loss which may be suffered. The Company may charge such Member for its reasonable out-of-pocket expenses in replacing a Unit which has been mutilated, lost, destroyed or wrongfully taken.

Section 13.06 Vesting Terms; Resale Obligations.

(a) General. Unless otherwise provided in a restricted unit, employment or similar agreement between the Company and a Class B Member, all assignees and transferees (including spouses and former spouses) of holders of Class B Units shall be subject to this Section 13.06 regardless of the fact that any such assignee or transferee is not an employee of the Company, (i.e., if the employment of any Class B Member who assigned or transferred the Class B Units to such assignee or transferee is terminated, Section 13.06 shall apply to such Class B Units regardless of their ownership).

(b) Vesting Schedule. The Class B Units held by a Class B Member shall “vest” for purposes of Section 13.06(c) (i) 25% as of the date of grant and (ii) annually thereafter in equal portions on the first, second and third anniversary of the date of grant. Unvested Class B Units shall fully vest upon a Liquidation Event. Additionally, unvested Class B Units shall fully vest upon a termination of such Class B Member without Good Cause or the termination by such Class B Member for Good Reason.

(i) If a Class B Member’s employment is terminated by the Company other than for Good Cause, if a Class B Member resigns or if a Class B Member’s employment is terminated due to death or Disability (any such Person, a “Terminated Member”), the Company will have the right to repurchase, for cash, promptly, but in no case more than 120 Business Days, after the termination date (the “Company Class B Repurchase Period”), any or all of the vested Class B Units held by such Terminated Member at a price equal to the Fair Market Value of such Units. If the Company either affirmatively elects not to exercise such repurchase right or the Company has failed to exercise such repurchase right prior to the end of the Company Class B Repurchase Period, the SW Group or any of its respective Affiliates will be entitled to exercise such repurchase right on the same terms within 120 Business Days of receiving notice of either the Company’s election not to repurchase or the expiration of the Company Class B

Repurchase Period. All unvested Class B Units held by such Terminated Member shall automatically be cancelled and of no further economic effect without further action on the part of the Company or the Class B Member.

(ii) All Class B Units which are repurchased by, or forfeited to, the Company pursuant to this Section 13.06(c) shall become Class B Company Units and the same shall be noted on Exhibit B.

(iii) Notwithstanding any other provision of this Agreement, if a Class B Member’s employment with the Company is terminated and the Board determines that Good Cause exists or existed on, prior to, or after such termination (including by virtue of a material breach of an obligation to the Company under this Agreement or any Employment Agreement after such termination) (A) the number of Class B Units owned by such Member which have vested shall be reduced to zero and all unvested Class B Units shall automatically be cancelled and of no further economic effect without further action on the part of the Company or such employee and (B) to the extent that the Company has previously repurchased any Class B Units of such Member, all consideration for such Class B Units previously paid by the Company must be returned to the Company.

(d) Section 13.07 Assignment. The rights of the Company and the SW Group under this Article XIII may be assigned or transferred in whole or in part by the Company or the SW Group (in the case of the SW Group, to any transferee of Class A Units that will have a Class A Unit Sharing Percentage of at least 30% after giving effect to such Transfer) without any consent or other action on the part of any other party hereto.

ARTICLE XIV

Any purported Transfer in violation of this Article XIV and/or, if applicable, Article XIII hereof shall be void ab initio and of no force or effect. Other than Transfers pursuant to Article XIII hereof, each Member will cause any proposed transferee of any Unit to agree in writing, in an instrument in form and substance reasonably satisfactory to the Company, to take and hold such securities subject to the provisions and upon conditions specified in this Agreement. No Person shall make or suffer any Transfer of its, his or her Units if such Transfer would (i) cause the Company or any Member to become subject to regulation under either the Investment Company Act of 1940, as amended, or the Investment Advisers Act of 1940, as amended, or (ii) violate the registration provisions of the Securities Act or the registration or qualification provisions of any applicable securities law or (iii) cause the Company to be treated as a corporation for U.S.

federal income tax purposes.

If an existing Class B Member fails to have his or her spouse execute such agreement, the Class B Member shall thereafter lose all of his or her rights hereunder except for the rights of a mere assignee and the Board shall thereafter have all voting rights with respect to his or her interest.

(b) Any Class B Units held by an individual who has failed to get his or her spouse to execute an agreement in the form of Exhibit D and any Class B Units held by a Person who is an assignee shall be subject to the option of the Company or the SW Group or any of their respective Affiliates to acquire all of such Class B Units for the Fair Market Value of the vested Class B Units, as determined in accordance with Section 13.06(c)(iii).

(d) If a spouse or former spouse of a Class B Member acquires a Class B Unit in the Company without the prior approval of the Board, such spouse or former spouse hereby grants, as evidenced by Exhibit D, an irrevocable power of attorney (which shall be coupled with an interest) to the original Class B Member who held such Class B Units to vote or to give or withhold such approval as such original Class B Member shall himself or herself vote or approve with respect to such matter and without the necessity of the taking of any action by any such spouse or former spouse. Such power of attorney shall not be affected by the subsequent disability or incapacity of the spouse or former spouse granting such power of attorney. Furthermore, such spouse or former spouse agrees that the original Class B Member shall have the option at any time to purchase all of such Class B Units for the Fair Market Value of the vested Class B Units, as determined pursuant to Section 13.06(c)(iii), with such amount being payable as set forth in Section 13.06(c)(vii).

Upon the issuance of any class or series of Units in accordance with Section 4.01 and Section 11.08, the Board may amend any provision of this Agreement and may add any new provision to this Agreement, and execute, swear to, acknowledge, deliver, file and record an amended Certificate of Formation and whatever other documents may be required in connection therewith, as shall be necessary or desirable to reflect the issuance of such class or series of Units and the relative rights and preferences of such class or series of Units as to the matters set forth in the preceding sentence. The Board is authorized and directed to do all things it deems to be necessary or advisable in connection with any such future issuance to reflect the issuance of the Units and the admission of any Member acquiring the Units, including, without limitation, compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any securities exchange on which the Units or other such security is listed for trading.

(b) Notwithstanding anything in this Agreement to the contrary, the Company shall be authorized to issue up to 4,000,000 Class B Units.

Section 15.02 Preemptive Rights.

(a) Class A Preemptive Rights. Each Class A Member shall have a right of first refusal to purchase its pro rata share of all Equity Securities, as defined below, that the Company may, from time to time, propose to issue and sell after the date hereof, other than the Equity Securities excluded by Section 15.02(d) and Equity Securities issued in connection with the SW Commitment Amount, which shall be governed by Section 7.02. Each Class A Member’s pro rata share is equal to its Class A Unit Sharing Percentage.

exchangeable security), (iii) any security carrying any option, warrant or other right to subscribe to or purchase any Unit or (iv) any such option, warrant or other right.

(b) Exercise of Class A Preemptive Rights. If the Company proposes to issue any Equity Securities (other than Equity Securities excluded by Section 15.02(d) and Equity Securities issued in connection with the SW Commitment Amount, which shall be governed by Section 7.02), the Company shall give each Class A Member written notice of its intention, describing the Equity Securities, the price and terms and conditions upon which such Equity Securities are to be issued and/or sold. Each Class A Member shall have fifteen (15) days from the giving of such notice (the “Class A Option Period”) to agree to purchase its pro rata share of the Equity Securities for the price and upon the terms and conditions specified in the notice by giving written notice to the Company and stating therein the quantity of Equity Securities to be purchased. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Class A Member who would cause the Company to be in violation of applicable federal securities laws by virtue of such offer or sale.

(c) Transfer of Preemptive Rights. The preemptive rights of each Class A Member under this Section 15.02 may not be Transferred, except that such rights are assignable (i) by SW to any member of the SW Group and (ii) by any DLJ Member to any other member of the DLJ Group.

(d) Excluded Securities. The preemptive rights established by this Section 15.02 shall have no application to any of the following Equity Securities:

DISSOLUTION AND LIQUIDATION

Section 16.01 Dissolution. The Company shall be dissolved upon the determination of the Board.

(b) thereafter, to the Members in accordance with Article IX. If the foregoing distributions to the Members do not equal the Members’ respective positive Capital Account balances as determined after giving effect to the foregoing adjustments and to all adjustments attributable to allocations of Profits and Losses (or any items thereof) during the taxable year in question and all adjustments attributable to contributions and distributions of money and property effected prior to such distribution, then the allocations of Profits and Losses (or any items thereof) provided for in this Agreement shall be adjusted, including by the filing of amended tax returns to the extent necessary and possible, to the least extent necessary to produce a Capital Account balance for each Member which corresponds to the amount of the distribution to such Member.

Section 16.04 Negative Capital Accounts. No Member shall be liable to the Company or to any other Member for any negative balance outstanding in each such Member’s Capital Account, whether such negative Capital Account results from the allocation of Losses or other items of deduction and loss to such Member or from distributions to such Member, and such Member shall not have any obligation to make any contribution to the capital of the Company with respect to such deficit and such deficit shall not be considered a debt owed to the Company or, except as required by the DLLCA, to any other Person for any purpose whatsoever.

Section 17.03 Dispute Resolution. If a dispute between the Members that arises out of or relates to this Agreement, or the breach of this Agreement, and if the dispute cannot be settled through direct discussions, the parties agree to first endeavor to settle the dispute in an amicable manner by mediation, to be held in Houston, Texas, under the Commercial Mediation Rules of the AAA, before resorting to litigation. Thereafter, any unresolved controversy or claim arising out of or relating to this Agreement or breach of this Agreement shall be submitted to arbitration in accordance with Section 17.04.

Section 17.04 Arbitration. The parties acknowledge that the expeditious and equitable settlement of disputes arising under this Agreement is to their mutual advantage. To that end, the parties agree to use their best efforts to resolve all differences of opinion and to settle all disputes through joint cooperation and consultation. Any dispute, alleged breach, interpretation, challenge or disagreement whatsoever between or among any of the parties hereto with respect to the interpretation of, or relating to any alleged breach of, this Agreement (or any other agreement contemplated hereby or in connection herewith) that the parties are unable to settle within sixty (60) days, as set forth in the preceding sentence, shall be resolved by final and binding arbitration before a single arbitrator selected and serving under the Commercial Arbitration Rules of the American Arbitration Association.

Such arbitration shall be the exclusive remedy hereunder; provided that nothing contained in this Section 17.04 shall limit any party’s right to bring (i) post arbitration actions seeking to enforce an arbitration award or (ii) actions seeking injunctive or other similar relief in the event of a breach or threatened breach of any of the provisions of this Agreement (or any other agreement contemplated hereby or entered into in connection herewith).

Section 17.06 Entire Agreement; Amendments. This Agreement and its exhibits and the Contribution Agreement constitute the entire agreement among the Members relative to the formation of the Company and supersede all prior contracts or agreements with respect to the Company, whether oral or written. Except as set forth below, no amendment of this Agreement will be valid or binding upon the Members, nor will any waiver of any term of this Agreement be effective, unless in writing and signed by a Class A Majority; provided that any amendment or waiver that adversely impacts the rights or increases the obligations of any class of Membership Interests must be approved by a majority of the Membership Interests of such class; and provided further, that any amendment or waiver that adversely impacts the rights or increases the obligations of any Member of any class must be approved by such Member unless such amendment or waiver applies to all Members of such class generally. Notwithstanding the foregoing, subject to Section 11.08, the Board shall be authorized to amend this Agreement, without the approval of any Member with respect to any of the following matters:

(a) entering into Adoption Agreements with Persons that are transferees or new Members pursuant to the terms of this Agreement;

(b) amending this Agreement to satisfy any requirements, conditions, guidelines or opinions contained in any opinion, directive, order, ruling or regulation of the

(c) amending this Agreement to cure any ambiguity or correct or supplement any provision hereof that may be incomplete or inconsistent with any other provision hereof, so long as such amendment under this clause (c) does not adversely affect the interests of any Members; and

(d) amending this Agreement upon publication of final regulations in the Federal Register (or other official pronouncement), to provide for (i) the election of a safe harbor under U.S. Treasury Regulations Section 1.83-3(1) (or any similar provision) under which the fair market value of a partnership (or membership) interest that is transferred in connection with the performance of services is treated as being equal to the liquidation value of that interest, (ii) an agreement by the Company and all of its Members to comply with all the requirements set forth in such regulations and Revenue Procedure 2005-43 (and any other guidance provided by the IRS with respect to such election) with respect to all partnership (or membership) interests transferred in connection with the performance of services while the election remains effective, and (iii) any other related amendments.

Section 17.07 Waiver. No consent or waiver, express or implied, by any Member of any breach or default by any other Member in the performance by the other Member of his, her or its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such other Member of the same or any other obligation hereunder. Failure on the part of any Member to complain of any act or to declare any other Member in default, regardless of how long such failure continues, shall not constitute a waiver of rights hereunder.

Section 17.08 Severability. If any provision of this Agreement or the application thereof to any Person or circumstances shall be invalid or unenforceable to any extent, and such invalidity or unenforceability does not destroy the basis of the bargain between the parties, then the remainder of this Agreement and the application of such provisions to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

Section 17.13 Counterparts. This Agreement may be executed in any number of counterparts (including a facsimile thereof) with the same effect as if all signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument.
