                (a)   the Bank may at any time and from time to time, with or
     without judicial process or the aid and assistance of others, enter upon
     any premises in which any Collateral may be located and, without resistance
     or interference by Guarantor, take possession of the Collateral; and/or
     dispose of any Collateral on any such premises; and/or require Guarantor to
     assemble and make available to the Bank at the expense of Guarantor any
     Collateral at any place and time designated by the Bank which is reasonably
     convenient to both parties; and/or remove any Collateral from any such
     premises for the purpose of effecting sale or other disposition thereof
     (and if any of the Collateral consists of motor vehicles, the Bank may use
     Guarantor's license plates); and/or sell, resell, lease, assign and
     deliver, grant options for or otherwise dispose of any Collateral in its
     then condition or following any commercially reasonable preparation or
     processing, at public or private sale or proceedings or otherwise, by one
     or more contracts, in one or more parcels, at the same or different times,
     with or without having the Collateral at the place of sale or other
     disposition, for cash and/or credit, and upon any terms, at such place(s)
     and time(s) and to such person(s) as the Bank deem best, all without
     demand, notice or advertisement whatsoever except that where an applicable
     statute requires reasonable notice of sale or other disposition Guarantor
     hereby agrees that the sending of five days' notice by registered or
     certified mail, return receipt requested, to any address of Guarantor set
     forth in this Security Agreement shall be deemed reasonable notice thereof.
     If any Collateral is sold by the Bank upon credit or for future delivery,
     the Bank shall not be liable for the failure of the purchaser to pay for
     same and in such event the Bank may resell such Collateral.  The Bank may
     buy any Collateral at any public sale and, if any Collateral is of a type
     customarily sold in a recognized market or is of the type which is the
     subject of widely distributed standard price quotations, the Bank may buy
     such Collateral at private sale and in each case may make payment therefor
     by any means.  The Bank may apply the sale proceeds actually received from
     any sale or other disposition to the reasonable expenses of retaking,
     holding, preparing for sale, selling, leasing and the like, to reasonable
     attorneys' fees and all legal, travel and other expenses which may be
     incurred by the Bank in attempting to collect the Obligations or enforce
     this Security Agreement or in the prosecution or defense of any action or
     proceeding related to the subject matter of this Security Agreement; and
     then to the Obligations in such order and as to principal or interest as
     the Bank may desire; and Guarantor shall remain liable and will pay the
     Bank on demand any deficiency remaining, together with interest thereon
     at the highest rate then payable on the Obligations and the balance of any
     expenses unpaid, with any surplus to be paid to Guarantor, subject to any
     duty of the Bank imposed by law to the holder of any subordinate security
     interest in the Collateral known to the Bank; 



                (b)   The Bank may appropriate, set off and apply to the payment
     of the Obligations, any Collateral in or coming into the possession of the
     Bank or their agents, without notice to Guarantor and in such manner as the
     Bank may in their discretion determine.

          7.    DESIGNATION AND AUTHORIZATION.  To effectuate the terms and 
provisions hereof, Guarantor hereby designates and appoints the Bank and each of
its designees or agents as attorney-in-fact of Guarantor, irrevocably and with
power of substitution, with authority, after the occurrence of a Default, to:
receive, open and dispose of all mail addressed to Guarantor and notify the
Post Office authorities to change the address for delivery of mail addressed to
Guarantor to such address as the Bank may designate; endorse the name of 
Guarantor on any notes, acceptances, checks, drafts, money orders, instruments
or other evidences of Collateral that may come into the Bank's possession; sign
the name of Guarantor on any invoices, documents, drafts against and notices to
account debtors or obligors of Guarantor, assignments and requests for
verification of accounts; execute proofs of claim and loss; execute
endorsements, assignments of other instruments of conveyance or transfer; adjust
and compromise any claims under insurance policies or otherwise; execute
releases; and do all other acts and things necessary or advisable in the sole
discretion of the Bank to carry out and enforce this Security Agreement or the
Obligations.  All acts done under the foregoing authorization are hereby
ratified and approved and neither the Bank nor any designee or agent thereof
shall be liable for any acts of commission or omission, for any error of
judgment or for any mistake of fact or law.  This power of attorney being
coupled with an interest is irrevocable while any Obligations shall remain
unpaid.

          8.    PRESERVATION AND DISPOSITION OF COLLATERAL; 
MISCELLANEOUS.  The Bank shall have the duty to exercise reasonable care in the
custody and preservation of any Collateral in its possession, which duty shall
be fully satisfied if the Bank maintains safe custody of such Collateral.
Except as hereinabove specifically set forth, the Bank shall not be deemed to
assume any other responsibility for, or obligation or duty with respect to, any
Collateral, or its use, of any nature or kind, or any matter or proceedings
arising out of or relating thereto, including, without limitation, any
obligation or duty to take any action to collect, preserve or protect its or
Guarantor's rights in the Collateral or against any prior parties thereto, but
the same shall be at Guarantor's sole risk and responsibility at all times.
Guarantor hereby releases the Bank from any claims, causes of action and demands
at any time arising out of or with respect to this Security Agreement, the
Obligations, the Collateral and its use and/or any actions taken or omitted to
be taken by the Bank with respect thereto, and Guarantor hereby agrees to hold
the Bank harmless from and with respect to any and all such claims, causes of
action and demands.  The Bank's prior recourse to any Collateral shall not
constitute a condition of any demand, suit or proceeding for payment or
collection of the Obligations.  No act, omission or delay by the Bank shall
constitute a waiver of its rights and remedies hereunder or otherwise.  No
single or partial waiver by the Bank of any Default or right or remedy which it
may have shall operate as a waiver of any other Default, right or remedy or of
the same Default, right or remedy on a future occasion.  Guarantor hereby waives
presentment, notice of dishonor and protest of all instruments included in or
evidencing any Obligations or Collateral, and all other notices and demands
whatsoever (except as expressly provided herein).  In the event of any litigati
on with respect to any matter connected with this Security Agreement, the
Obligations or the Collateral, Guarantor hereby waives the right to a trial by
jury.  Guarantor hereby irrevocably consents to the jurisdiction of the Courts
of the State of California and of any Federal Court located in such State in
connection with any action or proceeding arising out of or relating to the

Obligations, this Security Agreement or the Collateral, or any document or
instrument delivered with respect to any of the Obligations.  Guarantor hereby
waives personal service of any process in connection with any such action or
proceeding and agrees that the service thereof may be made by certified or
registered mail directed to Guarantor at any address of Guarantor set forth in
this Security Agreement.  Guarantor so served shall appear or answer to such
process within thirty (30) days after the mailing thereof.  Should Guarantor
so served fail to appear or answer within said thirty (30) day period, Guarantor
shall be deemed in default and judgment may be entered by the Bank against
Guarantor for the amount or such other relief as may be demanded in any process
so served.  In the alternative, in its discretion, the Bank may effect service
upon Guarantor in any other form or manner permitted by law.  All capitalized
terms used and not otherwise defined shall have the meanings set forth in the
Credit Agreement and other terms herein shall have the meanings as defined in
the UCC, unless the context otherwise requires.  No provision hereof shall be
modified, altered or limited except by a written instrument expressly referring
to this Security Agreement and to such provision, and executed by the party to
be charged.  This Security Agreement and all Obligations shall be binding upon
the successors, or assigns of Guarantor and shall, together with the rights and
remedies of the Bank hereunder, inure to the benefit of the Bank and their
successors, endorsees and assigns.  This Security Agreement and the Obligations
shall be governed in all respects by the laws of the State of California applic
able to contracts executed and to be performed in such State.  If any term of
this Security Agreement shall be held to be invalid, illegal or unenforceable,
the validity of all other terms hereof shall in no way be affected thereby.
The Bank is authorized to annex hereto any schedules referred to herein.
Guarantor acknowledges receipt of a copy of this Security Agreement.
