In the event that any Stockholder Designee shall fail to be elected to the Board at any meeting of shareholders called for the purpose of electing directors (or consent in lieu of meeting), the Company shall use its best efforts to cause such Blackstone Designee (or a new designee of the Blackstone Designator), Fortress Designee (or a new designee of Fortress) or Summit Designee (or a new designee of the Summit Designator), as applicable, to be elected to the Board, as soon as possible, and the Company shall take or cause to be taken, to the fullest extent permitted by applicable Law, at any time and from time to time, all actions necessary to accomplish the same, including, without limitation, actions to effect an increase in the Total Number of Directors.

(d)    The Company agrees, to the fullest extent permitted by applicable Law (including with respect to any fiduciary duties under Delaware law), to include in the slate of nominees recommended by the Board for election at any meeting of stockholders called for the purpose of electing Directors the persons designated pursuant to this Section 2.1 (to the extent that Directors of such nominee’s class are to be elected at such meeting, for so long as the Board is classified) and to nominate and recommend each such individual to be elected as a Director as provided herein, and to solicit proxies or consents in favor thereof and to cause the applicable proxies to vote in accordance with the foregoing. The Company and the Directors shall take all necessary corporate action, to the fullest extent permitted by applicable Law (including with respect to any

8

fiduciary duties under Delaware law), to (x) enable the Blackstone Designator, Fortress and the Summit Designator to nominate and effect the election or appointment of their respective designated individuals, whether by increasing the size of the Board, or otherwise and (y) designate the requisite number of additional individuals specified by the Blackstone Designator, Fortress or the Summit Designator to fill such newly created vacancies or to fill any other existing vacancies, as warranted.

(e)    In addition to any vote or consent of the Board or the shareholders of the Company required by applicable Law or the certificate of incorporation or other organizational document of the Company, and notwithstanding anything to the contrary in this Agreement, for so long as this Agreement is in effect, any action by the Board to increase or decrease the Total Number of Directors (other than any increase in the Total Number of Directors in connection with the election of one or more Directors elected exclusively by the holders of one or more classes or series of the Company’s securities other than common stock) shall require the prior written consent of the Blackstone Designator, delivered in accordance with Section 5.13 hereof.

2.2.    Compensation. Except to the extent the Blackstone Designator, Fortress or the Summit Designator may otherwise notify the Company, the Stockholder Designees shall be entitled to compensation consistent with the compensation received by other non-employee Directors, including any fees and equity awards, provided that (x) to the extent any Director compensation is payable in the form of equity awards, at the election of a Stockholder Designee, in lieu of any equity award, such compensation shall be paid in an amount of cash equal to the value of the equity award as of the date of the award, with any such cash subject to the same vesting terms, if any, as the equity awarded to other Directors and (y) at the election of a Stockholder Designee, any Director compensation (whether cash, equity awards and/or cash in lieu of equity as may be designated by the electing Stockholder Designee) shall be paid to a Stockholder Party or an Affiliate thereof specified by such Stockholder Designee rather than to such Stockholder Designee. If the Company adopts a policy that Directors own a minimum amount of equity in the Company, the Stockholder Designees shall not be subject to such policy.

2.3.    Other Rights of Stockholder Designees. Except as provided in Section 2.2, each Stockholder Designee serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of the foregoing, the Company shall indemnify, exculpate, and reimburse fees and expenses of the Stockholder Designees and provide the Stockholder Designees with director and officer insurance to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the certificate of incorporation, bylaws or other organizational document of the Company, applicable Law or otherwise.

2.4.    Board Observer Rights. So long as the Fortress Holders Beneficially Own at least 50% of the shares the Fortress Holders Beneficially Own immediately following the consummation of the Merger, Fortress shall have the right to designate (and remove) a representative (the “Fortress Observer”) who shall (1) have the right to receive (when and as received by Directors) due notice of and to attend (whether in person or by telephone) and participate in discussions at (but not vote on any matters on which the Directors are entitled to vote) all meetings of the Board and (2) have the right to receive copies of all documents and

9

other information, including minutes, consents, business plans, presentation materials, monthly management reports, budgets and financial information furnished generally to members of the Board when and as received by the Directors (“Board Materials”). The Company shall pay the reasonable out-of-pocket expenses incurred by the Fortress Observer in connection with the meetings of the Board, so long as such expenses have not otherwise been reimbursed pursuant to any management, employment or advisory agreements with the Company or Fortress. Notwithstanding anything to the contrary herein or otherwise, if counsel to the Company or a majority of the Board determines in good faith that allowing the Fortress Observer to (a) receive, inspect, review or otherwise have access to any Board Materials, or (b) be present for consideration of any matter to be considered by the Board, would be in conflict with an obligation of confidentiality owed by the Company or the fiduciary obligations of the Directors or would potentially result in the loss of any attorney-client or other privilege, then the Company shall not be required to furnish or make available to the Fortress Observer (and the Fortress Observer shall have no right to receive) related Board Materials and the Board may exclude the Fortress Observer from, and the Fortress Observer shall have no right to be present for, consideration of such matter. For the avoidance of doubt, the Fortress Observer shall have no voting rights nor any fiduciary duty to the Company or its shareholders.

(b)    None of (i) the Stockholder Parties or any of their Affiliates or (ii) any Non-Employee Director (including any Non-Employee Director who serves as an officer of the Company in both his or her director and officer capacities) or his or her Affiliates (the Persons identified in (i) and (ii) above being referred to, collectively, as “Identified Persons” and, individually, as an “Identified Person”) shall, to the fullest extent permitted by law, have any duty to refrain from directly or indirectly (1) engaging in the same or similar business activities or lines of business in which the Company or any of its Affiliates now engages or proposes to engage or (2) otherwise competing with the Company or any of its Affiliates, and, to the fullest extent permitted by law, no Identified Person shall be liable to the Company or its stockholders or to any Affiliate of the Company for breach of any fiduciary duty solely by reason of the fact that such Identified Person engages in any such activities. To the fullest extent permitted by law, the Company hereby renounces any interest or expectancy in, or right to be offered an opportunity to participate in, any business opportunity that may be a corporate opportunity for an Identified Person and the Company or any of its Affiliates, except as provided in Section 3.3(c). Subject to said Section 3.3(c), in the event that any Identified Person acquires knowledge of a potential transaction or other business opportunity that may be a corporate opportunity for itself, herself or himself and the Company or any of its Affiliates, such Identified Person shall, to the fullest extent permitted by law, have no duty to communicate or offer such transaction or other business opportunity to the Company or any of its Affiliates and, to the fullest extent permitted by law, shall not be liable to the Company or its stockholders or to any Affiliate of the Company for breach of any fiduciary duty as a stockholder, director or officer of the Company solely by reason of the fact that such Identified Person pursues or acquires such corporate opportunity for itself, herself or himself, or offers or directs such corporate opportunity to another Person or does not communicate information regarding such corporate opportunity to the Company.

(c)    Notwithstanding the foregoing provisions of this Section 3.3, the Company does not renounce its interest in any corporate opportunity offered to any Non-Employee Director (including any Non-Employee Director who serves as an officer of the Company) if such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of the Company, and the provisions of Section 3.3(b) shall not apply to any such corporate opportunity.

(d)    In addition to and notwithstanding the foregoing provisions of this Section 3.3, a potential corporate opportunity shall not be deemed to be a corporate opportunity for the Company if it is a business opportunity that (i) the Company is neither financially or legally able, nor contractually permitted to undertake, (ii) from its nature, is not in the line of the Company’s business or is of no practical advantage to the Company or (iii) is one in which the Company has no interest or reasonable expectancy.

(e)    For purposes of this Section 3.3, “Affiliate” shall mean (a) in respect of any Stockholder Party, any Person that, directly or indirectly, is controlled by a Stockholder Party, controls a Stockholder Party or is under common control with a Stockholder Party and shall include any principal, member, director, partner, stockholder, officer, employee or other representative of any of the foregoing (other than the Company and any entity that is controlled

12

by the Company), (b) in respect of a Non-Employee Director, any Person that, directly or indirectly, is controlled by such Non-Employee Director (other than the Company and any entity that is controlled by the Company) and (c) in respect of the Company, any Person that, directly or indirectly, is controlled by the Company.

(f)    For purposes of this Section 3.3, “control,” including the terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting stock, by contract, or otherwise. A Person who is the owner of 20% or more of the outstanding voting stock of any corporation, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary. Notwithstanding the foregoing, a presumption of control shall not apply where such Person holds voting stock, in good faith and not for the purpose of circumventing this Section, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group have control of such entity.

(b)    Except as expressly set forth in this Agreement, neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence.

Thereafter, such Stockholder Party shall cease to be a party to this Agreement, shall have no further rights or obligations hereunder and none of the terms or provisions hereof shall have any continuing force and effect with respect to such Stockholder Party.

(e)    Any party hereto may unilaterally waive any of its rights hereunder in a signed writing delivered to the Company.

This Agreement will inure to the benefit of and be binding on the parties hereto and their respective successors and permitted assigns.

17

5.9.    Specific Performance. Each party hereto acknowledges and agrees that in the event of any breach of this Agreement by any of them, the other parties hereto would be irreparably harmed and could not be made whole by monetary damages.

5.15.    Effectiveness; Termination of Existing Stockholders and Securityholders Agreements. This Agreement shall be valid and enforceable as of the date of this Agreement and

18

may not be revoked by any party hereto; provided that the provisions herein (other than this Article V) shall not be effective until the consummation of the Merger.
