         THIS AMENDMENT TO LOAN DOCUMENTS (this "Amendment") is entered into
between Silicon Valley Bank ("Silicon") and the borrower named above
("Borrower").

         Silicon and Borrower agree to amend the Loan and Security Agreement

The definition of the "$40 Million Requirement" set forth in Section 1 of the
Amended and Restated Schedule to Loan and Security Agreement that currently
reads as follows:

                  provided that Loans under this subclause 1(a) shall only be
                  available to Borrower as long as Borrower maintains, at all
                  times, at least $40,000,000, in the aggregate, in accounts
                  maintained at Silicon, SVB Asset Management and SVB Securities
                  (including unrestricted cash, cash equivalents (excluding any
                  Revolving Loans under this Agreement), short term investments
                  and long term investments (provided, however, such long term
                  investments cannot exceed $5,000,000 in the aggregate for
                  purposes of this requirement)) (the "$40 Million
                  Requirement");

is hereby amended to read as follows:

                  provided that Loans under this subclause 1(a) shall only be
                  available to Borrower as long as Borrower maintains, at all
                  times, at least $30,000,000, in the aggregate, in accounts
                  maintained at Silicon, SVB Asset Management and SVB Securities
                  (including unrestricted cash, cash equivalents (excluding any
                  Revolving Loans under this Agreement), short term investments
                  and long term investments (provided, however, such long term
                  investments cannot exceed $5,000,000 in the aggregate for
                  purposes of this requirement)) (the "$30 Million
                  Requirement");

All references to the "$40 Million Requirement" in the Loan Agreement shall
hereinafter mean the "$30 Million Requirement."

         2. Extension of Maturity Date with Respect to Revolving Loans. The
Maturity Date with respect to the Revolving Loans and related Obligations is
hereby amended from "September 29, 2005" to "December 28, 2005".
