THIS AMENDMENT TO LOAN DOCUMENTS is entered into between Silicon Valley Bank
("Silicon") and the borrower named above ("Borrower").
The Parties agree to amend the Loan and Security Agreement between them, dated
February 20, 2001 (as otherwise amended, if at all, the "Loan Agreement"), as
follows, effective as of the date hereof. (Capitalized terms used but not
defined in this Amendment shall have the meanings set forth in the Loan
Agreement.)
1. Modified Interest Rate. Section 2 of the Schedule to Loan and Security
Agreement is hereby amended to read as follows:
 
2. INTEREST.

Interest Rate (Section 1.2):
A rate equal to the "Prime Rate" in effect from time to time, plus 2.5% per
annum; provided that the interest rate in effect on any day shall not be less
than 6.5% per annum. Interest shall be calculated on the basis of a 360-day year
for the actual number of days elapsed. "Prime Rate" means the rate announced
from time to time by Silicon as its "prime rate;" it is a base rate upon which
other rates charged by Silicon are based, and it is not necessarily the best
rate available at Silicon. The interest rate applicable to the Obligations shall
change on each date there is a change in the Prime Rate.
 
Minimum Monthly Interest (Section 1.2):
 
    $3,000.
 
2. Modified Maturity Date. Section 4 of the Schedule to Loan and Security
Agreement is hereby amended to read as follows:
 
4. MATURITY DATE (Section 6.1): 
 
                           October 30, 2004.
 
3. Fee. In consideration for Silicon entering into this Amendment, Borrower
shall concurrently pay Silicon a fee in the amount of $20,000, 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.
 
4.  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.
 
5.  General Provisions. T his 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 under­standings between the parties with respect to the subject
hereof. Except as herein expressly amended, all of the terms and provisions of
the Loan Agreement, and all other documents and agreements between Silicon and
Borrower shall continue in full force and effect and the same are hereby
ratified and confirmed.
