       6.  Miscellaneous.
           ------------- 

           (a) Except as herein expressly amended, all terms, covenants and
provisions of the Credit Agreement are and shall remain in full force and effect

the Credit Agreement as amended by this Amendment. This Amendment shall be
deemed incorporated into, and a part of, the Credit Agreement.

           (b) This Amendment shall be binding upon and inure to the benefit of
the parties hereto and thereto and their respective successors and assigns. No
third party beneficiaries are intended in connection with this Amendment.

with the law of the State of California.

           (d) This Amendment may be executed in any number of counterparts,

shall constitute but one and the same instrument. Each of the parties hereto
understands and agrees that this document (and any other document required
herein) may be delivered by any party thereto either in the form of an executed
original or an executed original sent by facsimile transmission to be followed
promptly by mailing of a hard copy original, and that receipt by the Bank of a
facsimile transmitted document purportedly bearing the signature of the Borrower
shall bind the Borrower with the same force and effect as the delivery of a hard
copy original. Any failure by the Bank to receive the hard copy executed
original of such document shall not diminish the binding effect of receipt of
the facsimile transmitted executed original of such document which hard copy
page was not received by the Bank

           (e) This Amendment, together with the Credit Agreement, contains the
entire and exclusive agreement of the parties hereto with reference to the
matters discussed herein and therein.  This Amendment supersedes all prior
drafts and communications with respect thereto.
