         THIS SCHEDULE is an integral part of the Loan Agreement between
Silicon Valley Bank ("Silicon") and the above-named borrower ("Borrower").


REVOLVING LOAN CREDIT        An amount not to exceed the lesser of:  
LIMIT (SECTION 1.2):         (i) $1,000,000 at any one time outstanding; or (ii)
                             the amount of the Certificate of Deposit pledged to
                             Silicon by Borrower pursuant to the Pledge 
                             Agreement dated February 13, 1997.

                             year for the actual number of days elapsed.

                             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.
