          (d)  The Company is entering into this Amendment on the basis of its

     4.  Effective Date.  This Amendment will become effective as of November
         --------------                                                      
___, 1994 (the "Effective Date"), provided that each of the following conditions
                --------------    --------

execution and delivery by the Agent and the Banks of this Amendment shall not be
deemed to create a course of dealing or otherwise obligate the Agent or the
Banks to forbear or execute similar amendments under the same or similar
circumstances in the future.

     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
and all references therein to such Credit Agreement shall henceforth refer to
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.

                                       2

 
          (c)  This Amendment shall be governed by and construed in accordance
with the law of the State of California.

          (d)  This Amendment may be executed in any number of counterparts,
each of which shall be deemed an original, but all such counterparts together

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 Agent of a
facsimile transmitted document purportedly bearing the signature of a Bank or
the Company shall bind such Bank or the Company, respectively, with the same
force and effect as the delivery of a hard copy original.  Any failure by the
Agent 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 of the party whose hard copy page was not received by
the Agent.

          (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.  This Amendment may not be
amended except in accordance with the provisions of Section 10.01 of the Credit
Agreement.

          (f)  If any term or provision of this Amendment shall be deemed
prohibited by or invalid under any applicable law, such provision shall be
invalidated without affecting the remaining provisions of this Amendment or the
Credit Agreement, respectively.

          (g)  The Company covenants to pay to or reimburse the Agent and the
Banks, upon demand, for all costs and expenses (including allocated costs of in-
house counsel) incurred in connection with the development, preparation,
negotiation, execution and delivery of this Amendment, including without
limitation appraisal, audit, search and filing fees incurred in connection
therewith.

          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Amendment as of the date first above written.
