CORPORATE GOVERNANCE

2.1 Board Representation.

(a) Following the Listing Date, the CD&R Investor shall have the right, but not the obligation, to designate for nomination by the Board as Directors a number of designees equal to at least: (i) at least a majority of the total number of Directors

4

comprising the Board at such time as long as the CD&R Investor beneficially owns at least 50% of the outstanding shares of the Common Stock; (ii) at least 40% of the total number of Directors comprising the Board at such time as long as the CD&R Investor beneficially owns at least 40% but less than 50% of the outstanding shares of the Common Stock; (iii) at least 30% of the total number of Directors comprising the Board at such time as long as the CD&R Investor beneficially owns at least 30% but less than 40% of the outstanding shares of the Common Stock; (iv) at least 20% of the total number of Directors comprising the Board at such time as long as the CD&R Investor beneficially owns at least 20% but less than 30% of the outstanding shares of the Common Stock; and (v) at least 5% of the total number of Directors comprising the Board at such time as long as the CD&R Investor beneficially owns at least 5% but less than 20% of the outstanding shares of the Common Stock. For purposes of calculating the number of CD&R Designees that the CD&R Investor is entitled to designate for nomination pursuant to the formula outlined above, any fractional amounts would be rounded up to the nearest whole number and the calculation would be made on a pro forma basis after taking into account any increase in the size of the Board.

(b) In the event that the CD&R Investor has designated for nomination by the Board less than the total number of designees the CD&R Investor shall be entitled to designate for nomination pursuant to Section 2.1(a), the CD&R Investor shall have the right, at any time, to designate for nomination such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action, to the fullest extent permitted by Applicable Law (including with respect to any fiduciary duties under Delaware law), to (x) enable the CD&R Investor to designate for nomination and effect the election or appointment of such additional individuals, whether by increasing the size of the Board, or otherwise, and (y) to designate such additional individuals designated for nomination by the CD&R Investor to fill such newly-created vacancies or to fill any other existing vacancies. Each such individual whom the CD&R Investor shall actually designate for nomination pursuant to this Section 2.1 and who is thereafter elected to the Board to serve as a Director shall be referred to herein as a “CD&R Designee.”

(c) In the event that a vacancy is created at any time by the death, retirement or resignation of any Director designated by the CD&R Investor pursuant to this Section 2.1, the remaining Directors and the Company shall, to the fullest extent permitted by Applicable Law (including with respect to any fiduciary duties under Delaware law), cause the vacancy created thereby to be filled by a new designee of the CD&R Investor, if such Director was designated by the CD&R Investor, as soon as possible, and the Company hereby agrees to take, to the fullest extent permitted by Applicable Law (including with respect to any fiduciary duties under Delaware law), at any time and from time to time, all actions necessary to accomplish the same.

5

(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 individuals designated pursuant to this Section 2.1 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. The Company is entitled to identify such individual as a CD&R Designee pursuant to this Agreement.

(e) For so long as the CD&R Investor beneficially owns at least 25% of the outstanding shares of the Common Stock, a CD&R Designee shall serve as the Chairman of the Board (“Chairman”) and in such capacity as Chairman shall preside over meetings of the Board and the stockholders, among other duties.

(f) Insofar as the Company is or becomes subject to requirements under Applicable Law or the regulations of any self-regulatory organization, including the NYSE or such other national securities exchange upon which the Common Stock is listed to which the Company is then subject, relating to the composition of the Board or committees thereof, their respective responsibilities or the qualifications of their respective members, the CD&R Investor shall cooperate in good faith to select for nomination its designees to the Board under this Section 2.1 so as to permit the Company to comply with all such applicable requirements.

(g) No CD&R Designee shall be paid any fee (or provided any equity-based compensation) for service as Director or member of any committee of the Board, unless otherwise determined by the Board; provided that each CD&R Designee shall be entitled to reimbursement by the Company for reasonable expenses incurred while traveling to and from Board and committee meetings as well as travel for other business related to his or her service on the Board or committees thereof, subject to any maximum reimbursement obligations as may be established by the Board from time to time. Notwithstanding the foregoing, any CD&R Designee whom the Board determines to be “independent” as defined under NYSE and Exchange Act rules and regulations shall be entitled to compensation in accordance with the Company’s Independent Director Compensation Program.

2.2 Available Financial Information. Upon written request of the CD&R Investor, the Company will deliver, or cause to be delivered, to the CD&R Investor or its designated Representative:

(a) as soon as available after the end of each month and in any event within 30 days thereafter, a consolidated balance sheet of the Company and its Subsidiaries as of the end of such month and consolidated statements of operations, income, cash flows, retained earnings and stockholders’ equity of the Company and its Subsidiaries, for each month and for the current fiscal year of the Company to date, prepared in accordance

The Company covenants and agrees to deliver to the CD&R Investor, upon written request, so long as the CD&R Investor shall beneficially own at least 5% of the outstanding shares of Common Stock, with reasonable promptness, such other information and data (including such information and reports made available to any lender of the Company or any of its Subsidiaries under any credit agreement or otherwise) with respect to the Company and each of its Subsidiaries as from time to time may be reasonably requested by the CD&R Investor; provided that the Company reserves the right to withhold any information under this Section 2.3 or access under Section 2.4 from the CD&R Investor if the Board determines that providing such information or granting such access would reasonably be expected to adversely affect the Company on a competitive basis or otherwise. The CD&R Investor shall have access to such other information concerning the Company’s business or financial condition and the Company’s management as may be reasonably requested, including all information that is necessary for (x) each of the CD&R Investor and its Affiliates to comply with income tax reporting and regulatory requirements and (y) the CD&R Investor to prepare its quarterly and annual financial statements.

2.4 Access.
