Loan Modification Agreement in no way shall obligate Bank to make any future
modifications to the Obligations. Nothing in this Loan Modification Agreement

Bank
<PAGE>

and Borrower to retain as liable parties all makers of Existing Loan Documents,
unless the party is expressly released by Bank in writing. No maker will be

reason of this Loan Modification Agreement; provided, however, that if for any
reason Bank cannot avail itself of the courts of the Commonwealth of
Massachusetts, then venue shall lie in Santa Clara County, California.

13. COUNTERSIGNATURE/EFFECTIVENESS. This Loan Modification Agreement shall
become effective only (i) when it shall have been executed by Borrower and Bank,
