                           LOAN MODIFICATION AGREEMENT

     This Loan Modification Agreement is entered into as of March 5, 1997, by

Drive, Milpitas, CA 95035, and Silicon Valley Bank ("Silicon") whose address 
is 3003 Tasman Drive, Santa Clara, CA 95054.
     
1.   DESCRIPTION OF EXISTING INDEBTEDNESS:  Among other indebtedness which 
may be owing by Borrower to Silicon, Borrower is indebted to Silicon pursuant 
to, among other documents, a Loan and Security Agreement, dated March 10, 
1992 (including the Schedule thereto), as may be amended from time to time 
(the "Loan Agreement").  The Loan Agreement provided for, among other things, 
a Credit Limit in the original principal amount of Five Hundred Thousand and 
00/100 Dollars ($500,000.00) (the "A/R Facility").  The A/R Facility has been 
modified pursuant to, among other documents, a Loan Modification Agreement 
dated November 15, 1996, pursuant to which, among other things, the Credit 
Limit was decreased to One Hundred Eighty Five Thousand and 00/100 Dollars 
($185,000.00) and a Loan Modification Agreement dated  January 15, 1997, 
pursuant to among other things, the Credit Limit was increased to Five 
Hundred Thousand and 00/100 Dollars ($500,000.00).  Defined terms used but 
not otherwise defined herein shall have the same meanings as in the Loan 
Agreement.  

Hereinafter, all indebtedness owing by Borrower to Silicon shall be referred 
to as the "Indebtedness."

2.   DESCRIPTION OF COLLATERAL AND GUARANTIES:  Repayment of the Indebtedness 
is secured by the Collateral as described in the Loan Agreement.

Hereinafter, the above-described security documents and guaranties, together 
with all other documents  securing repayment of the Indebtedness shall be 
referred to as the "Security Documents."  Hereinafter, the Security 
Documents, together with all other documents evidencing or securing the 
Indebtedness shall be referred to as the "Existing Loan Documents."

                                                           Form 10-QSB (3/31/97)

                    PROFITABILITY:  Borrower shall be profitable (after
                    taxes) on a quarterly basis with an allowance for
                    losses not to exceed $300,000.00 for the quarter

4.   CONSISTENT CHANGES. The Existing Loan Documents are hereby amended 
wherever necessary to reflect the changes described above.

5.   PAYMENT OF LOAN FEE. Borrower shall pay to Silicon a fee in the amount 
of Five Thousand and 00/100 Dollars ($5000.00) (the "Loan Fee") plus all 
out-of-pocket expenses.

6.   NO DEFENSES OF BORROWER. Borrower (and each guarantor and pledgor signing
below) agrees that it has no defenses against the obligations to pay any
amounts under the Indebtedness.

7.   CONTINUING VALIDITY. Borrower (and each guarantor and pledgor signing 
below) understands and agrees that in modifying the existing Indebtedness, 
Silicon is relying upon Borrower's representations, warranties, and 
agreements, as set forth in the Existing Loan Documents.  Except as expressly 
modified pursuant to this Loan Modification Agreement, the terms of the 
Existing Loan Documents remain unchanged and in full force and effect.  
Silicon's agreement to modifications to the existing Indebtedness pursuant to 
this Loan Modification Agreement in no way shall obligate Silicon to make any 
future modifications to the Indebtedness.  Nothing in this Loan Modification 
Agreement shall constitute a satisfaction of the Indebtedness. It is the 
intention of Silicon and Borrower to retain as liable parties all makers and 
endorsers of Existing Loan Documents, unless the party is expressly released 
by Silicon in writing.  No maker, endorser, or guarantor will be released 
by virtue of this Loan Modification Agreement.  The terms of this paragraph 
apply not only to this Loan Modification Agreement, but also to all 
subsequent loan modification agreements.

8.   CONDITIONS. The effectiveness of this Loan Modification Agreement is
conditioned upon Borrower's payment of the Loan Fee.

     This Loan Modification Agreement is executed as of the date first written
above.
