1.                                       Bank
hereby waives Borrower’s existing default under the Loan Agreement by virtue of

OF INTELLECTUAL PROPERTY SECURITY AGREEMENT.  Borrower hereby ratifies, confirms and reaffirms, all and
singular, the terms and conditions of a certain Intellectual Property Security
Agreement dated as of December 19, 2002 between Borrower and Bank, and
acknowledges, confirms and agrees that said Intellectual Property Security
Agreement contains an accurate and complete listing of all

Security Agreement, shall remain in full force and effect.

 

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

 

7.                                       RATIFICATION
OF LOAN DOCUMENTS.  Borrower hereby
ratifies, confirms, and reaffirms all terms and conditions of all security or
other collateral granted to the Bank, and confirms that the indebtedness
secured thereby includes, without limitation, the Obligations.

 

8.                                       NO
DEFENSES OF BORROWER.  Borrower
hereby acknowledges and agrees that Borrower has no offsets, defenses, claims,
or counterclaims against Bank with respect to the Obligations, or otherwise,
and that if Borrower now has, or ever did have, any offsets, defenses, claims,
or counterclaims against Bank, whether known or unknown, at law or in equity,
all of them are hereby expressly WAIVED and Borrower hereby RELEASES Bank from
any liability thereunder.

 

9.                                       CONTINUING
VALIDITY.  Borrower understands and
agrees that in modifying the existing Obligations, Bank is relying upon
Borrower’s representations, warranties, and agreements, as set forth in the
Existing Loan Documents.  Except as
expressly modified pursuant to this Fourth Amendment, 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 Fourth Amendment in no way shall obligate
Bank to make any future modifications to the Obligations.  Nothing in this Fourth Amendment shall
constitute a satisfaction of the Obligations. 
It is the

 

3

 

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 Fourth Amendment.

 

10.                                 COUNTERSIGNATURE.  This Fourth Amendment shall become effective
only when it shall have been executed by Borrower and Bank (provided, however,
in no event shall this Fourth Amendment become effective until signed by an
officer of Bank in California).
