                                         during the term of this Agreement; (y)
                                         such a process introduces uncertainty
                                         as to the amounts required for
                                         Borrower's financial covenant
                                         compliance in the future; and (z)
                                         regardless of any such uncertainty,
                                         however, Borrower knowingly and without
                                         reservation agrees to the foregoing
                                         procedure and fully understands that
                                         Events of Default may arise from
                                         Borrower's non-compliance with such
                                         later-established amounts.

                                         above is to be used by the Bank in

                                         covenant levels for later periods
                                         during the term of this Agreement; (y)
                                         such a process introduces uncertainty
                                         as to the amounts required for
                                         Borrower's financial covenant

                                         reservation agrees to the foregoing
                                         procedure and fully understands that
                                         Events of Default may arise from
                                         Borrower's non-compliance with such
                                         later-established amounts.

         3.       RESERVES; WARRANT.

                  (a) Without limiting the generality of Item (4) set forth in
         Exhibit E to the Loan Agreement, Borrower hereby acknowledges and
         reaffirms that the Asset Based Terms are currently in effect and that,
         while the Asset Based Terms are in effect, Bank has the right in good
         faith to establish and maintain, from time to time, reserves as set
         forth in such Item (4) against the amount of Advances, Letters of
         Credit, and other financial accommodations otherwise available under
         the Loan Agreement.

                  (b) Without limiting the generality of clause (a) above and
         without limiting the Bank's rights and discretion relative to any other
         reserves, Borrower and Bank hereby acknowledge and agree that: (i) as
         circumstances currently exist, it is the Bank's good faith belief that
         a reserve in the amount of $1,500,000 against the amount of Advances,
         Letters of Credit, and other financial accommodations otherwise
         available under the Loan Agreement is appropriate due to, and
         accordingly established and maintained for, negative trends of
         Borrower's financial performance against plan and of Collateral
         performance (the "Negative Trends Reserve"); (ii) subject to the terms
         and conditions

         SILICON VALLEY BANK                       AMENDMENT TO LOAN DOCUMENTS

         hereof, Borrower has requested that Bank, and Bank hereby agrees to,
         temporarily reduce the amount of the Negative Trends Reserve (based on
         circumstances as they currently exist) from $1,500,000 to $1,000,000
         solely for the consecutive-90-day period commencing on August 7, 2003
         and ending on November 5, 2003 (the "Temporary Negative Trends Reserve
         Reduction"); and (iii) in consideration for Bank entering into this
         Amendment (including with respect to the Temporary Negative Trends
         Reserve Reduction), on the date of execution and delivery of this
         Amendment (the "Target Date") Borrower shall provide Bank with ten-year
         warrants to purchase 5,000 shares of common stock of the Parent, at a
         price per share equal to the Target Date Designated Price (as defined
         herein), on terms acceptable to Bank, all as set forth in the Warrant
         to Purchase Stock (the "August 2003 Warrant") and related documentation
         (if any) being executed concurrently herewith. The August 2003 Warrant
         shall be deemed fully earned on the Target Date, shall be in addition
         to all interest and other fees, and shall be non-refundable. As used
         herein, the term "Target Date Designated Price" means the average
         closing price of one share of the Parent's common stock reported for
         the 5 trading days immediately before the Target Date.

         4.       FEES. In consideration for Bank entering into this Amendment,
Borrower shall issue the August 2003 Warrant and pay Bank a fee of $20,000
concurrently with the execution and delivery of this Amendment, which fee shall
be non-refundable and in addition to all interest and other fees payable to Bank
under the Loan Documents. Bank is authorized to charge said fees to Borrower's
loan account.

         5.       REPRESENTATIONS TRUE. Borrower represents and warrants to Bank
that all representations and warranties set forth in the Loan Agreement, as
amended hereby, are true and correct.

         6.       GENERAL PROVISIONS. This Amendment, the Loan Agreement, any
prior written amendments to the Loan Agreement signed by Bank and Borrower, and
the other Loan Documents 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 expressly
amended herein (or as amended and restated in the Loan Documents as expressly
contemplated herein), all of the terms and provisions of the Loan Agreement and
all other Loan Documents shall continue in full force and effect and the same
are hereby ratified and confirmed.

counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same document.
