After giving effect to the Acquisitions, the Borrower will be a holding company that directly owns, and the sole assets of which are, all of the equity interests in the Targets. The Borrower, Archway and its subsidiaries and Razor and its subsidiaries are hereinafter referred to collectively as the “Relevant Entities”.

You have also advised Bank of America that you intend to finance in part the Acquisitions, the costs and expenses related to the Transaction (as hereinafter defined) and the ongoing working capital and other general corporate purposes of the Relevant Entities after consummation of the Acquisitions from the following sources (and that no financing other than the financing described herein will be required to consummate the Transaction): (a) at least $98.4 million in cash of the Borrower held in the Trust Account (defined below) and (b) up to $30 million in a senior secured revolving credit facility of the Borrower (the “Senior Credit Facility”). The Acquisitions, the entering into and funding of the Senior Credit Facility and all related transactions are hereinafter collectively referred to as the “Transaction”. The sources and uses for the financing for the Transaction are as set forth on Schedule I hereto.

In connection with the foregoing, Bank of America is pleased to offer its commitment to provide the full principal amount of the Senior Credit Facility upon and subject to the terms and conditions set forth in this letter (this “Commitment Letter”) and in the Summary of Terms and Conditions attached as Exhibit A hereto and incorporated herein by this reference (the “Summary of Terms”).

You hereby agree that, effective upon your acceptance of this Commitment Letter and continuing through January 31, 2009, you shall not solicit any other bank, investment bank, financial institution, person or entity to provide, structure, arrange or syndicate any component of the Senior Credit Facility or any other senior financing similar to or as a replacement of any component of the Senior Credit Facility unless we have advised you that we will not provide the Senior Credit Facility on the terms set forth in this Commitment Letter and the Summary of Terms.

The commitment of Bank of America hereunder is subject to (a) the satisfaction of each of the conditions precedent set forth in the Summary of Terms and (b) the accuracy and completeness of all representations that you and your affiliates make to Bank of America and your compliance with the terms of this Commitment Letter (including the Summary of Terms) and the Fee Letter (as hereinafter defined)

You represent, warrant and covenant that (a) all financial projections concerning the Relevant Entities that have been made available to Bank of America by you or any of your representatives (or on your or their behalf) (the “Projections”) have been prepared in good faith based upon reasonable assumptions and (b) all information, other than Projections, which has been made available to Bank of America by you or

any of your representatives (or on your or their behalf) in connection with any aspect of the Transaction (the “Information”) is complete and correct in all material respects and does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading. In issuing this commitment, Bank of America is and will be using and relying on the Projections and Information without independent verification thereof.

By executing this Commitment Letter, you agree to reimburse Bank of America from time to time on demand for all reasonable out-of-pocket fees and expenses (including, but not limited to, (a) the reasonable fees, disbursements and other charges of counsel to Bank of America and (b) due diligence expenses) incurred in connection with the Senior Credit Facility, the preparation of the definitive documentation therefor, any other aspect of the Transaction and any other transaction contemplated hereby (not to exceed $100,000).

You agree to indemnify and hold harmless Bank of America and each of its affiliates and their respective officers, directors, employees, agents, advisors and other representatives (each, an “Indemnified Party”) from and against (and will reimburse each Indemnified Party as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable fees, disbursements and other charges of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (a) any aspect of the Transaction or any other transaction contemplated hereby or (b) the Senior Credit Facility and any other financings, or any use made or proposed to be made with the proceeds thereof except to the extent such claim, damage, loss, liability or expense is found in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by you, your equityholders or creditors or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Transaction is consummated. You also agree that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to you or your subsidiaries or affiliates or to your or their respective equity holders or creditors arising out of, related to or in connection with any aspect of the Transaction, except to the extent of direct, as opposed to special, indirect, consequential or punitive, damages determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. Notwithstanding any other provision of this Commitment Letter, no Indemnified Party shall be liable for any damages arising from the use by others of information or other materials obtained through electronic telecommunications or other information transmission systems, other than for direct or actual damages resulting from the gross negligence or willful misconduct of such Indemnified Party as determined by a final and nonappealable judgment of a court of competent jurisdiction.
