     Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

     Reference is made to the responses to Items 1, 2, 3, 4 and 5 of this Statement which is incorporated by reference in response to this Item.

     Pursuant to the Stock Purchase Agreement, the Issuer agreed to appoint to its board of directors (the “Board”) a person nominated by the GTCR Funds, who initially is Collin E. Roche. The GTCR Funds continue to have the right to maintain their designee on the Board so long as the GTCR Funds continue to own at least 50% of the securities issued to the GTCR Funds and other purchasers pursuant to the Stock Purchase Agreement. In the event that the GTCR Funds do not have a designee on the Board but hold at least 4.9% of the outstanding Common Stock (calculated assuming conversion of the Preferred Stock), the GTCR Funds will be entitled to designate an individual to attend, but not vote at, all meetings of the Board and to receive all materials distributed to the members of the Board. The Stock Purchase Agreement provides also that the GTCR Funds may not, without the consent of the Issuer, acquire stock of the Issuer such that the aggregate number of shares held by the GTCR Funds would exceed 14.9% of the Issuer’s voting stock. The GTCR Funds agreed further, subject to certain exceptions, not to sell, transfer or otherwise dispose of, or enter into any hedging transaction with respect to, the shares of Common Stock acquired pursuant to the Purchase Agreement (including any shares of Common Stock resulting from conversion of Preferred Stock) for a period of one year with respect to 50% of such shares and a period to two years with respect to the remaining 50% of such shares. The Issuer paid the out-of-pocket fees and expenses incurred by the GTCR Funds in connection with the Stock Purchase Agreement, up to $1.0 million.

     The GTCR Funds, the Issuer and other investors of the Issuer are parties to a Preemptive and Registration Rights Agreement, dated as of December 11, 2007 (the “Registration Agreement”), which, subject to certain conditions and limitations, include, among others, the following provisions. This agreement grants to Fund IX/A, so long as Fund IX/A and its affiliates continue to hold 25% of the of the Common Stock acquired by the GTCR Funds pursuant to the Stock Purchase Agreement (calculated by counting the Preferred Stock as if it had been converted to Common Stock), or if Fund IX/A and its affiliates do not hold such amount, the holders of 50% of the Registrable Securities, the right, at any time after December 11, 2008, to demand that the Issuer file a registration statement with the Commission. Such registration statement must register for sale at least 25% (or a lower percentage if the aggregate net offering price exceeds $50,000,000) of the Common Stock then outstanding which has not been registered and which was (a) issued pursuant to the Stock Purchase Agreement, (b) issued in respect of any shares of Common Stock or Preferred Stock issued pursuant to the Stock Purchase Agreement and (c) otherwise acquired by GTCR Funds and the other investors party to the Registration Agreement. The shares of Common Stock referred to in (a), (b) and (c) are collectively referred to herein as the “Registrable Securities.” The Registration Agreement also requires the Issuer to file with the Commission, within nine months of the date of the Registration Agreement, a shelf registration statement, which, once it is declared effective by the Commission, Fund IX/A or the holders of 50% of the Registrable Securities may draw down upon an unlimited number of times to register for resale at least 25% of the Registrable Securities (or a lower percentage if the aggregate net offering price exceeds $25,000,000). The GTCR Funds and the other investors party to the Registration Agreement have also the right to include their Registrable Securities on other registration statements filed by the Issuer with the Commission. The Issuer agreed to use its commercially reasonable efforts or, in certain circumstances, its reasonable best efforts to have any of the registration statements described above declared effective by the Commission, to cause such registration statements to remain effective for certain periods, to indemnify the holders of Regsitrable Securities in certain circumstances and to pay certain expenses related to the registrations described above. The Registration Agreement prohibits the Issuer from granting to any other person or entity the right to request, or to include securities other than Common Stock in, a demand registration. The Registration Agreement also grants the holders of Registrable Securities (including GTCR IX/A and its affiliates) the right to participate in certain registered public offerings of the Issuer’s securities, whether offered by the Company or its stockholders.

     The Registration Agreement requires also that, so long as Fund IX/A and its affiliates maintain a beneficial ownership greater than 5.0% of the outstanding Common Stock of the Issuer (calculated assuming conversion of the Preferred Stock), in the event the Issuer makes an equity offering of Common Stock (other than in certain circumstances primarily related to compensation plans and acquisitions) for cash, the Issuer must afford Fund IX/A and its affiliates the right to acquire Common Stock from the Issuer on the same terms as in such equity offering. Fund IX/A and its affiliates may purchase in such equity offering shares of Common Stock such that the aggregate percentage beneficial ownership of Common Stock of Fund IX/A and its affiliates before such offering is unchanged following such offering. A copy of the Registration Agreement has been filed as an exhibit hereto and is incorporated herein by reference.

     In connection with the Stock Purchase Agreement, the GTCR Funds and the Issuer also entered into a Side Letter Agreement, dated as of November 26, 2007 (the “Side Letter Agreement”), whereby the parties confirmed their understanding and agreement regarding certain matters relating to the transactions contemplated by the Stock Purchase Agreement and the Registration Agreement. A copy of the Side Letter Agreement has been filed as an exhibit hereto and is incorporated herein by reference.
