     WHEREAS, the Lenders have made, are making and will be making loans to Parent to be secured by certain collateral; and

     WHEREAS, it is desirable to provide for the orderly administration of such collateral by requiring each Lender to appoint the Collateral Agent, and the Collateral Agent has agreed to accept such appointment and to receive, hold and deliver such collateral, all upon the terms and subject to the conditions hereinafter set forth; and

     WHEREAS, it is desirable to allocate the enforcement of certain rights of the Lenders under the Notes for the orderly administration thereof.

     NOW, THEREFORE, in consideration of the premises set forth herein and for other good and valuable consideration, the parties hereto agree as follows:

     1.      Collateral.

          (a)      Prior to or contemporaneously with the execution and delivery of this Agreement by the Collateral Agent and the Lenders, (i) the Collateral Agent has or will have entered into a Security Agreement with Parent and Guarantor (“Security Agreement”), regarding the grant of a security interest in the assets of Parent and Guarantor (such assets are referred to herein and in the Security Agreement as the “Collateral”) to the Collateral Agent, for the benefit of the Lenders, (ii) Guarantor will have executed and delivered a “Guaranty” in favor of Lenders in connection with the Obligations (as defined in the Security Agreements), and (iii) Parent is issuing the Notes to the Lenders pursuant to Subscription Agreements dated at or about May 11, 2007 and the date of this Agreement (collectively, each a “Subscription Agreement”). Collectively, the Security Agreement, the Notes and Subscription Agreement and other agreements referred to therein are referred to herein as “Borrower Documents”. All defined terms not otherwise defined herein shall have the meanings attributed to them in the Security Agreement.

          (b)      The Collateral Agent hereby acknowledges that any Collateral held by the Collateral Agent is held for the benefit of the Lenders in accordance with this Agreement and the Borrower Documents. No reference to the Borrower Documents or any other instrument or document shall be deemed to incorporate any term or provision thereof into this Agreement unless expressly so provided.

          (c)      The Collateral Agent is to distribute in accordance with the Borrower Documents any proceeds received from the Collateral which are distributable to the Lenders as set forth in Section 10.4 of the Security Agreement.

     2.      Appointment of the Collateral Agent.

1

     The Lenders hereby appoint the Collateral Agent (and the Collateral Agent hereby accepts such appointment) to take any action including, without limitation, the registration of any Collateral in the name of the Collateral Agent or its nominees prior to or during the continuance of an Event of Default (as defined in the Borrower Documents), the exercise of voting rights, if any, upon the occurrence and during the continuance of an Event of Default, the application of any cash collateral received by the Collateral Agent to the payment of the Obligations, the making of any demand under the Borrower Documents, the exercise of any remedies given to the Collateral Agent pursuant to the Borrower Documents and the exercise of any authority pursuant to the appointment of the Collateral Agent as an attorney-in-fact pursuant to the Security Agreement that the Collateral Agent deems necessary or proper for the administration of the Collateral pursuant to the Security Agreement. Upon disposition of the Collateral in accordance with the Borrower Documents, the Collateral Agent shall promptly distribute any cash or Collateral in accordance with Section 10.4 of the Security Agreement. Parent and Lenders must notify Collateral Agent in writing of the issuance of Notes to Lenders by Parent. Additional Lenders may become subject to the rights and benefits of this Agreement by participating in the Offering and executing and delivering a copy of this Agreement to the Collateral Agent and Company. Schedule A may be amended from time to time to include such additional Lenders. The Collateral Agent will not be required to act hereunder in connection with Notes the issuance of which was not disclosed in writing to the Collateral Agent nor will the Collateral Agent be required to act on behalf of any assignee of Notes without the written consent of Collateral Agent.

     3.      Action by the Majority in Interest.

          (a)      Certain Actions. Each of the Lenders covenants and agrees that only a Majority in Interest shall have the right, but not the obligation, to undertake the following actions (it being expressly understood that less than a Majority in Interest hereby expressly waive the following rights that they may otherwise have under the Borrower Documents):

               (i)      Acceleration. If an Event of Default occurs, after the applicable cure period, if any, a Majority in Interest may, on behalf of all the Lenders, instruct the Collateral Agent to provide to Parent and/or Guarantor notice to cure such default and/or declare the unpaid principal amount of the Notes to be due and payable, together with any and all accrued interest thereon and all costs payable pursuant to such Notes;

               (ii)      Enforcement. Upon the occurrence of any Event of Default after the applicable cure period, if any, a Majority in Interest may instruct the Collateral Agent to proceed to protect, exercise and enforce, on behalf of all the Lenders, their rights and remedies under the Borrower Documents against Parent and/or Guarantor, and such other rights and remedies as are provided by law or equity; and

               (iii)      Waiver of Past Defaults. A Majority in Interest may instruct the Collateral Agent to waive any Event of Default by written notice to Parent and/or Guarantor, and the other Lenders, but not waive damages accrued or accruing until the effective date of such waiver.

          (b)      Permitted Subordination and Release. A Majority in Interest may instruct the Collateral Agent to agree to release in whole or in part or to subordinate any Collateral to any claim or other actual or proposed security interest and may enter into any agreement with Parent and/or Guarantor to evidence such subordination; provided, however, that subsequent to any such release or subordination, each Note shall remain pari passu with the other Notes held by the Lenders.

2

          (c)      Further Actions. A Majority in Interest may instruct the Collateral Agent to take any other action described in Section 13(h) of the Subscription Agreement and subject to the conditions described in Section 13(h) of the Subscription Agreement by instructing the Collateral Agent in writing to take such action on behalf of all the Lenders.

          (d)      Majority in Interest. For so long as any obligations remain outstanding on the Notes, Majority in Interest for the purposes of this Agreement and the Borrower Documents shall mean Lenders who hold not less than seventy percent (70%) of the outstanding principal amount of the Notes on the date such Majority in Interest instructs the Collateral Agent.

     4.      Power of Attorney.

          (a)      To effectuate the terms and provisions hereof, the Lenders hereby appoint the Collateral Agent as their attorney-in-fact (and the Collateral Agent hereby accepts such appointment) for the purpose of carrying out the provisions of this Agreement including, without limitation, taking any action on behalf of, or at the instruction of, the Majority in Interest at the written direction of the Majority in Interest and executing any consent authorized pursuant to this Agreement and taking any action and executing any instrument that the Collateral Agent may deem necessary or advisable (and lawful) to accomplish the purposes hereof.

          (b)      All acts done under the foregoing authorization are hereby ratified and approved and neither the Collateral Agent nor any designee nor agent thereof shall be liable for any acts of commission or omission, for any error of judgment, for any mistake of fact or law except for acts of gross negligence or willful misconduct.

     11.      Miscellaneous.

          (a)      Rights and Remedies Not Waived. No act, omission or delay by the Collateral Agent shall constitute a waiver of the Collateral Agent’s rights and remedies hereunder or otherwise.
