Borrower hereby acknowledges the foregoing Reporting Default. Silicon hereby agrees to forbear from exercising its rights and remedies arising from the Reporting Default until the earlier of the following (the “Forbearance Period”): (i) April 15, 2005 or (ii) the occurrence of an Event of Default (other than the Reporting Default) under the Loan Agreement. It is understood by the parties hereto, however, that such forbearance does not constitute a waiver or forbearance of any other default under, or any other provision or term of, the Loan Agreement or any related document, nor an agreement by Silicon to waive or forbear from exercising its rights and remedies in the future regarding the Reporting Default or any other defaults under, or any other provision or term of, the Loan Agreement.

(b) Maximum Advances. The aggregate face amount of all Financed Receivables outstanding at any time may not exceed the Facility Amount, and Bank shall have no obligation to make Advances in excess of Five Hundred Thousand Dollars ($500,000) in the aggregate at any time outstanding.

3. Modified Applicable Rate. The Applicable Rate set forth in Section 13.1 of the Loan Agreement is hereby amended to read as follows:

“Applicable Rate” is a per annum rate equal to the Prime Rate plus eight percent (8.0%).

4. Modified Facility Amount. The Facility Amount set forth in Section 13.1 of the Loan Agreement is hereby amended to read as follows:

“Facility Amount” is Six Hundred Twenty-Five Thousand Dollars ($625,000).

5. Modified Maturity Date. The Maturity Date set forth in Section 13.1 of the Loan Agreement is hereby amended to read as follows:

“Maturity Date” is April 30, 2005.

6. Fee. In consideration for Silicon entering into this Amendment, Borrower shall concurrently pay Silicon a fee in the amount of $1,000, which shall be non-refundable and in addition to all interest and other fees payable to Silicon under the Loan Documents. Silicon is authorized to charge said fee to Borrower’s loan account.

7. Representations True. Borrower represents and warrants to Silicon that all representations and warranties set forth in the Loan Agreement, as amended hereby, are true and correct.

8. General Provisions. This Amendment, the Loan Agreement, any prior written amendments to the Loan Agreement signed by Silicon and Borrower, and the other written documents and agreements between Silicon and Borrower set forth in full all of the representations and agreements of the parties with respect to the subject matter hereof and supersede all prior discussions, representations, agreements and under-standings between the parties with respect to the subject hereof.
