ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On August 31, 2006, Riviera Tool Company (the "Company") entered into
an Omnibus Amendment with Laurus Master Fund, Ltd. ("Laurus"), amending the term
"Fixed Conversion Price" with respect to the Convertible Term Note (the "Term
Note"), dated as of May 17, 2005, by the Company in favor of Laurus in the
aggregate principal amount of $3,200,000 issued pursuant to the terms of the
Securities Purchase Agreement, dated as of May 17, 2005, between the Company and
Laurus. The term "Fixed Conversion Price," with respect solely to the Term Note,
was amended as follows:

         The initial Fixed Conversion Price means $1.66; provided, however, that
         in respect of the first $50,000 of aggregate principal amount (the
         "Initial Converted Amount") of the Term Note converted into shares of
         the Company's common stock, the Fixed Conversion Price in respect of
         such Initial Converted Amount (and the interest and fees associated
         therewith to the extent converted) shall be equal to $0.35.

         A prospectus supplement relating to the prospectus, dated August 17,
2006 (File No. 33-126659), of the Company was filed with the Commission on
August 31, 2006 reflecting such amended terms.
