          (ii) if the Stockholders beneficially own in the aggregate an amount of Common Stock that represents less than 40% of the outstanding shares of Common Stock, so long as either Stockholder beneficially owns at least 20% of the outstanding shares of Common Stock, in connection with any election of directors to the Board, the Company shall at the request of such Stockholder include two representatives designated by such Stockholder in the slate of directors recommended by the Board to the stockholders for election as directors; and provided, further that if either Stockholder ceases to beneficially own at least 20% of the outstanding shares of Common Stock but shall beneficially owns at least 5% of the outstanding shares of Common Stock, in connection with any election of directors to the Board, the Company shall at the request of such Stockholder include one representative designated by such Stockholder in the slate of directors recommended by the Board to the stockholders for election as directors; and

          (c) The initial directors designated by CA pursuant to Section 2.1(a) shall be George E. Matelich and Stanley de J. Osborne. The initial directors designated by CA II pursuant to Section 2.1(a) shall be Scott Lebovitz and Kenneth A. Pontarelli.

          (g) Solely for purposes of Section 2.1(a)(i), and in order to secure the performance of each Stockholder’s obligations under Section 2.1(a)(i), each Stockholder hereby irrevocably appoints each other Stockholder that qualifies as a Proxy Holder (as defined below) the attorney-in-fact and proxy of such Stockholder (with full power of substitution) to vote or provide a written consent with respect to its shares of Common Stock as described in this paragraph if, and only in the event that, such Stockholder fails to vote or provide a written consent with respect to its shares of Common Stock in accordance with the terms of Section 2.1(a)(i) (each such Stockholder, a “Breaching Stockholder”). Each Breaching Stockholder shall have five (5) Business Days from the date of a request for such vote or written consent (the “Cure Period”) to cure such failure.

Each Stockholder intends this proxy to be, and it shall be, irrevocable and coupled with an interest, and each Stockholder will take such further action and execute such other instruments as may be necessary to effectuate the intent of this proxy and hereby revoke any proxy previously granted by it with respect to the matters set forth in Section 2.1(a)(i) with respect to the shares of Common Stock owned by such Stockholder. Notwithstanding the foregoing, the conditional proxy granted by this Section 2.1(g) shall be deemed to be revoked upon the termination of Article II in accordance with its terms.

     Section 2.2 Additional Management Provisions.

          (a) For so long as the Stockholders beneficially own in the aggregate an amount of Common Stock that represents at least 40% of the outstanding shares of Common Stock, (i) each Stockholder that has the right to designate at least two Directors to the Board pursuant to Section 2.1(a)(i) shall have the right to have at least one (1) of its designated directors on any committee (with the exception of the Audit Committee and the Conflicts Committee) of the Board, to the extent such directors are permitted to serve on such committees under SEC and NYSE rules applicable to the Company, (ii) Sponsor Directors shall constitute the majority of each such committee (at least 50% in the case of the Nominating and Corporate Governance Committee and the Compensation Committee), and (iii) the Chairman of each such committee shall be a Sponsor Director. In the event that SEC or NYSE rules applicable to the Company limit the number of Sponsor Directors that can serve on any committee (other than the Audit Committee), the parties shall allocate committee membership among Sponsor Directors in as equitable a manner as possible, taking into account the relative level of ownership of the Stockholders in considering committee preferences.

          (b) Each Stockholder agrees and acknowledges that the directors designated by CA and CA II may share confidential, non-public information about the Company with Kelso and GSCP, respectively.

     Section 3.2 Tag Along Rights.

          (a) In the case of a proposed Transfer by a Stockholder (a “Transferring Stockholder”) of shares of Common Stock owned by such Stockholder, other than (i) to the Company, (ii) to a Permitted Transferee or (iii) to the public pursuant to an underwritten offering or Rule 144 under the Securities Act (a “Proposed Transfer”), each other Stockholder who exercises its rights under this Section 3.2(a) (a “Tagging Stockholder”) shall have the right to require the Transferring Stockholder to cause the proposed transferee (a “Proposed Transferee”) to purchase from such Tagging Stockholder up to a number of its shares of Common Stock equal to the product of (i) (A) the number of shares of Common Stock held by the Tagging Stockholder divided by (B) the number of shares of Common Stock held by all Stockholders participating in such Transfer and (ii) the aggregate number of shares of Common Stock proposed to be Transferred to the Proposed Transferee.

          (b) The Transferring Stockholder shall give notice to each other Stockholder of a Proposed Transfer not later than five (5) Business Days prior to the closing of the Proposed Transfer, setting forth the number of shares of Common Stock proposed to be so Transferred, the name and address of the Proposed Transferee, the proposed amount and form of consideration (and, if such consideration consists in part or in whole of property other than cash, the Transferring Stockholder shall provide such information, to the extent reasonably available to the Transferring Stockholder, relating to such non-cash consideration as the other Stockholders may reasonably request in order to evaluate such non-cash consideration), and other terms and conditions of payment offered by the Proposed Transferee. The Transferring Stockholder shall deliver or cause to be delivered to each Tagging Stockholder copies of all transaction documents relating to the Proposed Transfer as the same become available. The tag-along rights provided by this Section 3.2 must be exercised by a Stockholder within three (3) Business Days following receipt of the notice required by the first sentence of this Section 3.2(b), by delivery of a written notice to the Transferring Stockholder indicating its desire to exercise its rights and specifying the number of shares of Common Stock it desires to Transfer.

          (c) Any Transfer of shares of Common Stock by a Tagging Stockholder to a Proposed Transferee pursuant to this Section 3.2 shall be on the same terms and conditions (including, without limitation, price, time of payment and form of consideration) as to be paid to the Transferring Stockholder; provided that in order to be entitled to exercise its tag along right pursuant to this Section 3.2, each Tagging Stockholder must agree to make to the Proposed Transferee representations, warranties, covenants, indemnities and agreements the same mutatis mutandis as those made by the Transferring Stockholder in connection with the Proposed Transfer (other than any non-competition or similar agreements or covenants that would bind the Tagging Stockholder or its Affiliates), and agree to the same conditions to the Proposed Transfer as the Transferring Stockholder agrees, it being understood that all such representations, warranties, covenants, indemnities and agreements shall be made by the Transferring Stockholder and each Tagging Stockholder severally and not jointly and that, except with respect to individual representations, warranties, covenants, indemnities and other agreements of the Tagging Stockholder as to the unencumbered title to its shares of Common Stock and the power, authority and legal right to Transfer such shares of Common Stock, the aggregate amount of the liability of the Tagging Stockholder shall not exceed either (i) such Tagging Stockholder’s pro rata portion of any such liability to be determined in accordance with such Tagging Stockholder’s portion of the total number of shares of Common Stock included in such Transfer or (ii) the proceeds to such Tagging Stockholder in connection with such Transfer. Each Tagging Stockholder shall be responsible for its proportionate share of the costs of the Proposed Transfer to the extent not paid or reimbursed by the Proposed Transferee or the Company.

     Section 3.3 Substitute Stockholder.

          (a) Any Transfer of shares of Common Stock to any Permitted Transferee of a Stockholder, which Transfer is otherwise in compliance herewith, shall be permitted hereunder only if such Permitted Transferee agrees in writing that it shall, upon such Transfer, assume with respect to such shares of Common Stock the transferor’s obligations under this Agreement and become a party to this Agreement for such purpose, and any other agreement or instrument executed and delivered by such transferor in respect of the shares of Common Stock.

          (b) Notwithstanding the foregoing, Section 3.3(a) shall not apply to any Transfer to (i) the public under a Registration Statement or Rule 144 under the Securities Act or (ii) any general or limited partner, member or stockholder of any Stockholder.

     Section 3.5 Termination of Transfer Restrictions. The provisions of this Article III shall terminate and be of no further force and effect upon the earlier of (i) the fifth anniversary of the IPO or (ii) the date on which the Stockholders cease to hold collectively 25% of their Initial Post-IPO Share Ownership.

ARTICLE IV
GENERAL PROVISIONS

     Section 4.1 Termination. The provisions of Article II of this Agreement shall terminate as set forth in such Article. The provisions of Article III of this Agreement shall terminate as set forth in Section 3.5. The remainder of this Agreement shall terminate after each Stockholder shall have transferred all shares of Common Stock owned by it.

     Section 4.2 Subsequent Acquisition of Shares.

     Section 4.3 Waiver by Stockholders. The rights and obligations contained in this Agreement are in addition to the relevant provisions of the Certificate of Incorporation in force from time to time and shall be construed to comply with such provisions.

opportunity to the Company or any of its subsidiaries, as the case may be, and, notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company or any of its subsidiaries or any holder of Common Stock for breach of any duty (contractual or otherwise) by reason of the fact that such Stockholder, Sponsor Director or Affiliated Officer, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to the Company or any of its subsidiaries.

     Section 4.5 Notices. All notices, requests, demands, waivers and other communications required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered personally, (b) mailed, certified or registered mail with postage prepaid, (c) sent by next-day or overnight mail or delivery or (d) sent by fax, as follows (or to such other address as the party entitled to notice shall hereafter designate in accordance with the terms hereof):

     Section 4.11 Waivers. Waiver by any party hereto of any breach or default by any other party of any of the terms of this Agreement shall not operate as a waiver of any other breach or default, whether similar to or different from the breach or default waived.

     EACH PARTY HERETO HEREBY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF OR IN ANY WAY

     Section 4.12 Invalidity of Provision.

     Section 4.13 Amendments. This Agreement may not be amended, modified or supplemented except by a written instrument signed by the parties hereto.

     Section 4.14 Assignments. The provisions of this Agreement shall be binding upon and inure to the benefit of parties hereto and their respective heirs, legal representatives, successors and assigns. No Stockholder may assign any of its rights or obligations hereunder without the consent of the Company unless such assignment is in connection with a Transfer permitted by this Agreement and, prior to such assignment, such assignee complies with the requirements of Section 3.2 and Section 3.3, in each case, to the extent applicable.

     Section 4.15 No Third Party Beneficiaries. Except as otherwise provided herein, this Agreement is not intended to confer upon any Person, except for the parties hereto, any rights or remedies hereunder.

     Section 4.16 Specific Performance. It is hereby agreed and acknowledged that it will be impossible to measure the money damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them by this Agreement and that, in the event of any such failure, an aggrieved party will be irreparably damaged and will not have an adequate remedy at law. Any such party shall, therefore, be entitled (in addition to any other remedy to which such party may be entitled at law or in equity) to injunctive relief, including specific performance, to enforce such obligations, without the posting of any bond, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.
