NOW THEREFORE, in consideration of the premises, and the mutual covenants and agreements set forth herein, the Borrower and Bank hereby agree to amend the Loan and Security Agreement as follows:

Section A.             AMENDMENT

1.             The definition of “Letter of Credit Maturity Date” in Section 1.1 Defined Terms is hereby deleted and the following is inserted therefore:

“Letter of Credit Maturity Date” shall mean 15 months past the Revolving Loan A Maturity Date.

2.               The first sentence of Section 12.10 Letters of Credit is hereby deleted and the following is inserted therefore:

Section B.             NO OTHER CHANGE OF TERMS.

Except as amended by the foregoing, no other terms of the Loan and Security Agreement are in any way changed in this First Amendment and the Loan and Security Agreement shall continue in full force and effect in accordance with its original terms.  Reference to this specific Amendment need not be made in the Loan and Security Agreement, or any other instrument or document executed in connection therewith, any reference in any such items to the Loan and Security Agreement being sufficient to refer to the Loan and Security Agreement as amended hereby.

Section C.             CONDITIONS OF AMENDMENT.
