         with respect to each Letter of Credit for which it is
         the account party at the applicable Letter of Credit
         Fee rate per annum, payable on the average Equivalent

privilege, nor shall any future waiver of any right, power,
privilege or default hereunder, or under any agreement, contract,
indenture, document or instrument mentioned in the Agreement,
constitute a waiver of any other default of the same or of any
other term or provision.

         5.3  Counterparts.  This First Amendment may be
executed in any number of counterparts and all of such
counterparts taken together shall be deemed to constitute one and
the same instrument.  This First Amendment shall not become

bank shall have signed a copy hereof, whether the same or
counterparts, and the same shall have been delivered to the
Agent.

   First Amendment to First Amended and Restated Credit Agreement



Previously, the Board of Directors granted the authority to the
President and/or Executive Vice President to execute the $50,000,000
First Amended and Restated Credit Agreement dated May 24, 1996 (the
"Agreement") with Bank of America and Sanwa Bank California (the

are willing to amend the Agreement to permit such evergreen Letters of
Credit on the terms and conditions set forth in the "First Amendment
to First Amended and Restated Credit Agreement" (the "First Amendment")
dated as of September 17, 1996.

This will certify that the previous authority granted by the Board of
Directors also includes the execution, delivery, and performance of
amendments to the Agreement and related documents as required by the
Banks.  I further certify that said resolutions are still in full
force and effect and have not been amended or revoked.
