A.                                   Pursuant to a Credit and Security Agreement dated as of July 21, 2003, (as thereafter amended, supplemented or modified, the “Credit Agreement”) and a Revolving Note dated July 21, 2003 (as thereafter amended, supplemented or modified, the “Note”), OPTA SYSTEMS, LLC, a Delaware limited liability company (the “Borrower”) is indebted to Seller for a secured revolving loan (the “Loan”) in the original principal amount of Twenty Million Dollars ($20,000,000.00). The Credit Agreement was amended by the First Amended Forbearance Agreement that was executed by Borrower and Lender on July 22, 2005, by the Letter Agreement that was executed by Borrower and Lender on July 26, 2005, the Second Amended Forbearance Agreement that was executed by Borrower and Lender on August 25, 2006, the Third Amended Forbearance Agreement that was executed by Borrower and Lender as of October 13, 2005, and by the Letter Agreement that was executed by Borrower and Lender on January 12, 2006 (collectively, the “Forbearance Agreement”).

B.                                     The Loan is secured by a security interest in substantially all of Borrower’s personal property (other than intellectual property). The agreements, documents, and instruments securing the Loan (including the Credit Agreement) are referred to individually and collectively as the “Security Documents”. The Loan is guaranteed by Buyer, (in its capacity as guarantor, the “Guarantor”) pursuant to a Guaranty by Corporation, dated July 16, 2003 (the “Guaranty”). The Note, the Security Documents, the Guaranty and all other agreements, documents, and instruments evidencing, securing, or otherwise relating to the Loan, are sometimes herein referred to individually as a “Loan Document” and collectively as the “Loan Documents.”  Capitalized terms not otherwise defined herein shall have the same meanings ascribed to them in the Loan Documents.

C.                                     Buyer desires to purchase and Seller desires to sell the Loan.

NOW, THEREFORE, for good and valuable consideration, Seller and Buyer agree as follows:

Buyer’s indemnification obligations pursuant to this paragraph shall include any liabilities charged to Seller’s Account resulting from unpaid items, ACH overdrafts, or similar charges that were incurred prior to the Closing, but not yet processed, as well as any such charge incurred after the Closing. Buyer’s obligations to Seller under this paragraph shall survive sale and assignment of the Loan and Loan Documents pursuant to this Agreement.
