or about December&nbsp;1, 1997, the Borrower and the Bank entered into that certain Loan and Security Agreement, which was subsequently superceded and restated in
full pursuant to an Amended and Restated Loan and Security Agreement dated August&nbsp;9, 1999, and further modified by those certain Loan Modification Agreements dated May&nbsp;28, 1999,
November&nbsp;24, 1999, January&nbsp;31, 2000, May&nbsp;2, 2000, August&nbsp;15, 2000, April&nbsp;16, 2001, May&nbsp;23, 2001, and September&nbsp;28, 2001 (the Amended and Restated Loan
and Security Agreement and all Loan Modification Agreements collectively referred to herein as the "Loan Agreement"), pursuant to which the Bank made available to the Borrower a Committed Revolving
Line (the "Revolving Line") in the principal amount of up to Ten Million Dollars ($10,000,000). Each capitalized term used in this Modification shall have the meaning accorded to it in the Loan
Agreement unless it is otherwise defined herein. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;&nbsp;&nbsp;&nbsp;The
Borrower and the Bank hereby agree to amend the Loan Agreement further as follows, all subject to the terms and conditions of this Modification. </FONT></P>
