     This Loan Modification Agreement is entered into as of October 22, 1999, by

be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among

be amended from time to time, (the "Loan Agreement"). The Loan Agreement
provided for, among other things, a Revolving Committed Line in the original
principal amount of One Million Five Hundred Thousand Dollars ($1,500,000). The
Loan Agreement was amended pursuant to, among other documents, a Second
Amendment to Loan and Security Agreement, dated October 28, 1998 pursuant to
which, among other things, the Revolving Committed Line was amended to Ten
Million Dollars ($10,000,000). 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 Bank 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 and in that certain
Intellectual Property Security Agreement, dated October 28, 1998, by and between
Borrower and Bank.

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

this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect. Bank's agreement to modifications
to the existing Indebtedness pursuant to this Loan Modification Agreement in no

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