Section 5. Conversion.

Each share of Series A Preferred Stock is convertible into shares of Common Stock as provided in this Section 5.

(a) Mandatory Conversion. The Company shall seek such approval of the holders of the Company’s Common Stock as may be required under law or the primary exchange listing standards applicable to the Company to permit the conversion of the Series A Preferred Stock into shares of Common Stock at the regularly scheduled 2010 annual meeting of the shareholders of the Company or at such earlier date as the Company and a majority of the holders of the Series A Preferred Stock may agree (such approval, the “Shareholder Approval” and such meeting, the “Annual Meeting”). On the date on which the Shareholder Approval is obtained (the “Conversion Date”), each of the Series A Preferred Stock will automatically, and without any further action required by any holder, be converted into a number of duly authorized, validly issued, fully paid and nonassessable shares of Common Stock determined by dividing the Liquidation Preference by the Reference Price (the “Settlement Rate”); provided that, for purposes of this Section 5(a), (i) if the Reference Price is less than the Floor Price, then the Settlement Rate will be the Liquidation Preference divided by the Floor Price, and (ii) if the Reference Price is greater than the Ceiling Price, then the Settlement Rate will be the Liquidation Preference divided by the Ceiling Price, in each case, with the Floor Price and the Ceiling Price being subject to appropriate adjustments set forth in Section 5(d) below.

(b) Fractional Shares. No fractional shares of Common Stock will be issued upon conversion of the Series A Preferred Stock. In lieu of fractional shares, the Company shall, with respect to each fractional share otherwise deliverable (and subject to the next sentence), deliver a whole share of Common Stock or pay cash (subject to compliance with all laws, rules and regulations applicable to the Company (and including, for the avoidance of doubt, any Exchange listing requirements then applicable to the Company) and any debt instruments the Company is then party to, including the Credit Agreement, dated as of February 27, 2008, among the Company, as borrower, the lenders party thereto, JP Morgan Chase, N.A., as syndication

agent, and Bank of America, N.A., as administrative agent, collateral agent, swingline lender and issuing bank), as in effect on the date of this Certificate of Designation (the “Credit Agreement”). If more than one share of Series A Preferred Stock is being converted at one time by the same holder, then the number of full shares issuable upon conversion will be calculated on the basis of the aggregate number of shares of Series A Preferred Stock converted by such holder at such time.

(c) Mechanics of Conversion.

(i) In the event of mandatory conversion pursuant to Section 5(a), the Company shall deliver as promptly as practicable (but in no event later than three (3) Business Days after the Conversion Date) written notice to each holder of the Series A Preferred Stock specifying: (A) the Conversion Date; (B) the number of shares of Common Stock to be issued in respect of each share of Series A Preferred Stock that is converted; and (C) the place or places where the shares are to be surrendered for issuance of shares of Common Stock, which date shall be as soon as practicable following the Conversion Date.

(ii) As promptly as practicable (but in no event later than three (3) Business Days) following the later of the Conversion Date and the delivery by a holder thereof of the Series A Preferred Stock to the Company, the Company shall issue and deliver to such holder a number of shares of Common Stock to which such holder is entitled, together with a check or cash for payment of fractional shares, if any, in exchange for the shares of Series A Preferred Stock. Such conversion will be deemed to have been made on the Conversion Date, and the person (as defined in Section 7) entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Common Stock on such Conversion Date. The Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Common Stock upon conversion.

(iii) The Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock issuable upon conversion as set forth in this Section 5, which shares of Common Stock shall be issued free of any preemptive rights arising under law or contract and free from all taxes, liens and charges with respect to the issuance thereof.

(iv) From and after the Conversion Date, the shares of Series A Preferred Stock converted as of such Conversion Date will no longer be deemed to be outstanding, dividends will cease to accrue on the Series A Preferred Stock, and all rights of the holders of the Series A Preferred Stock will terminate except for the right to receive the number of whole shares of Common Stock issuable upon conversion thereof at the Settlement Rate then in effect and

cash or whole shares in lieu of any fractional shares of Common Stock. Any shares of Series A Preferred Stock that have been converted will, after such conversion, be deemed cancelled and retired.

(v) The Company shall comply with all federal and state laws, rules and regulations and applicable rules and regulations of the Exchange on which shares of the Common Stock are then listed. So long as the Common Stock into which the shares of Series A Preferred Stock are then convertible is then listed on an Exchange, the Company shall list and keep listed on such Exchange, upon official notice of issuance, all shares of such Common Stock issuable upon conversion.

(vi) Issuances of shares of Common Stock upon conversion of the Series A Preferred Stock shall be made without charge to any holder of shares of Series A Preferred Stock for any issue or transfer tax (other than taxes in respect of any transfer occurring contemporaneously therewith or as a result of the holder being a non-U.S. person) or other incidental expense in respect of the issuance of such shares, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance or delivery of shares of Common Stock in a name other than that of the holder of the Series A Preferred Stock to be converted, and no such issuance or delivery shall be made unless and until the person requesting such issuance or delivery has paid to the Company the amount of any such tax or has established, to the reasonable satisfaction of the Company, that such tax has been paid.

(d) Adjustments to Floor Price and Ceiling Price. The Floor Price and the Ceiling Price shall be adjusted from time to time by the Company, without duplication with Section 7(g), as follows (each event resulting in such adjustment pursuant to this Section 5(d), an “Adjustment Event”):

(i) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall (A) declare a dividend or make a distribution on its Common Stock in shares of Common Stock, (B) subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or (C) combine or reclassify the outstanding Common Stock into a smaller number of shares, each of the Floor Price and the Ceiling Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by multiplying each of the Floor Price and the Ceiling Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such action, and the denominator of which shall be the number of shares of Common Stock outstanding immediately following such action.

(ii) Statement Regarding Adjustments. Whenever either of the Floor Price or the Ceiling Price shall be adjusted as provided in this Section 5(d), the Company shall forthwith file, at the principal office of the Company, a statement showing in reasonable detail the facts requiring such adjustment, and each of the Floor Price or the Ceiling Price that shall be in effect after such adjustment and the Company shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to each holder of shares of Series A Preferred Stock at the address appearing in the Company’s records.
