reimburse Bank for all legal fees and expenses incurred in connection with this
amendment to the Existing Loan Documents.

5. CONSENT. Bank hereby consents to the acquisition by Borrower of Auxilor, Inc.
upon such terms and conditions as have been previously disclosed to Bank in

as expressly modified pursuant to 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 Obligations pursuant to this
Loan Modification Agreement in no way shall obligate Bank to make any future
modifications to the Obligations. Nothing in this Loan Modification Agreement
shall constitute a satisfaction of the Obligations. It is the intention of
Bank


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
released by virtue of this Loan Modification Agreement.

12. JURISDICTION/VENUE. Borrower accepts for itself and in connection with its

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,
(ii) after the Bank's review and approval of updated tax and UCC lien search

by all existing guarantors.
