                 (a)      No Default or Event of Default has occurred and is
continuing.

                 (b)      The execution, delivery and performance by the
Company of this Amendment have been duly authorized by all necessary corporate
and other action and do not and will not require any registration with, consent
or approval of, notice to or action by, any Person (including any Governmental
Authority) in order to be effective and enforceable.  The Credit Agreement as
amended by this Amendment constitutes the legal, valid and binding obligations
of the Company, enforceable against it in accordance with its respective terms.
without defense, counterclaim or offset.

                 (c)      All representations and warranties of the Company
contained in the Credit Agreement are true and correct.

                 (d)      The Company is entering into this Amendment on the
basis of its own investigation and for its own reasons, without reliance upon
the Agent and the Banks or any other Person.

         5.      Effective Date.  This Amendment will become effective on June
30, 1996 (the "Effective Date"), provided that the Agent has received from the
Company, each Guarantor, and each of the Banks a duly executed original (or, if
elected by the Agent, an executed facsimile copy) of this Amendment.

         6.      Reservation of Rights.  The Company acknowledges and agrees
that the 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 execute or agree to similar amendments under the same or
similar circumstances in the future.

         7.      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.

   5
                 (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 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 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 11.01 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.

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