                    (b) With the exception of the items specified in clause (c),

               or any  other  document,  instrument  or  agreement  between  the
               undersigned parties  (collectively in this Section 10.12(d),  the

               provided  in the  Comerica  Documents,  venue  for the  reference

                    (c) The matters that shall not be subject to a reference are
               the  following:  (i)  nonjudicial  foreclosure  of  any  security
               interests  in  real  or  personal  property,   (ii)  exercise  of
               self-help  remedies  (including,  without  limitation,  set-off),
               (iii)  appointment of a receiver and (iv) temporary,  provisional
               or ancillary remedies  (including,  without limitation,  writs of
               attachment, writs of possession,  temporary restraining orders or
               preliminary injunctions). This reference provision does not limit
               the right of any party to  exercise  or oppose  any of the rights
               and  remedies  described  in  clauses  (i) and (ii) or to seek or
               oppose from a court of  competent  jurisdiction  any of the items
               described  in  clauses  (iii)  and  (iv).  The  exercise  of,  or
               opposition to, any of those items does not waive the right of any
               party to a reference  pursuant  to this  reference  provision  as
               provided herein.

                    (d) The referee shall be a retired judge or justice selected
               by mutual written agreement of the parties. If the parties do not
               agree  within ten (10) days of a written  request to do so by any
               party,  then,  upon  request of any party,  the referee shall be
               selected  by the  Presiding  Judge  of the  Court (or his or her
               representative).  A request for  appointment of a referee may be
               heard on an ex parte or expedited  basis, and the parties  agree
               that  irreparable  harm  would  result if ex parte  relief is not
               granted  Pursuant to CCP  Section 170.6, each party shall have
               one peremptory challenge to the referee selected by the Presiding
               Judge of the Court (or his or her representative).

                    (e)  The  parties  agree  that  time  is of the  essence  in
               conducting the reference  proceedings.  Accordingly,  the referee
               shall  be  requested,  subject  to  change  in the  time  periods
               specified  herein for good cause shown, to (i) set the matter for
               a status and  trial-setting  conference  within fifteen (15) days
               after the date of selection of the referee,  (ii) if practicable,
               try all issues of law or fact  within one  hundred  twenty  (120)
               days  after  the  date  of the  conference  and  (iii)  report  a
               statement  of decision  within  twenty (20) days after the matter
               has been submitted for decision.

                    (f) The  referee  will  have  power to  expand  or limit the
               amount and duration of  discovery.  The referee may set or extend
               discovery  deadlines  or  cutoffs  for good  cause,  including  a
               party's  failure to provide  requested  discovery  for any reason
               whatsoever. Unless otherwise ordered based upon good cause shown,
               no party shall be entitled to "priority" in conducting discovery,
               depositions  may be taken by  either  party  upon  seven (7) days
               written  notice,  and all other  discovery  shall be responded to
               within fifteen (15) days after service.  All disputes relating to
               discovery which cannot

                                       3
<PAGE>

               be  resolved  by the parties  shall be  submitted  to the referee
               whose decision shall be final and binding.

                    (g) Except as expressly set forth herein,  the referee shall
               determine  the  manner  in  which  the  reference  proceeding  is
               conducted including the time and place of hearings,  the order of
               presentation of evidence, and all other questions that arise with
               respect  to  the  course  of  the   reference   proceeding.   All
               proceedings and hearings conducted before the referee, except for
               trial,  shall be conducted without a court reporter,  except that
               when any party so requests,  a court reporter will be used at any
               hearing  conducted  before the  referee,  and the referee will be
               provided a courtesy copy of the transcript. The party making such
               a request  shall have the  obligation  to arrange for and pay the
               court reporter.  Subject to the referee's power to award costs to
               the prevailing  party, the parties will equally share the cost of
               the referee and the court reporter at trial.

                    (h) The referee shall be required to determine all issues in
               accordance  with existing case law and the statutory  laws of the
               State  of  California.   The  rules  of  evidence  applicable  to
               proceedings at law in the State of California  will be applicable
               to the  reference  proceeding.  The referee shall be empowered to
               enter equitable as well as legal relief,  enter equitable  orders
               that will be binding on the parties and rule on any motion  which
               would be  authorized  in a court  proceeding,  including  without
               limitation motions for summary judgment or summary  adjudication.
               The referee  shall issue a decision at the close of the reference
               proceeding  which  disposes of all claims of the parties that are
               the subject of the  reference.  Pursuant to CCP Section 644, such
               decision  shall be entered by the Court as a judgment or an order
               in the same  manner as if the  action bad been tried by the Court
               and any such decision will be final, binding and conclusive.  The
               parties  reserve the right to appeal  from the Final  judgment or
               order or from any  appealable  decision  or order  entered by the
               referee.  The  parties  reserve  the right to  findings  of fact,
               conclusions  of laws, a written  statement  of decision,  and the
               right to move for a new trial or a different judgment,  which new
               trial,  if granted,  is also to be a reference  proceeding  under
               this provision.

                    (i)  If  the  enabling   legislation   which   provides  for
               appointment of a referee is repealed (and no successor statute is
               enacted), any dispute between the parties that would otherwise be
               determined by reference procedure will be resolved and determined
               by arbitration.  The  arbitration  will be conducted by a retired
               judge or justice, in accordance with the California

                                       4
<PAGE>

               Arbitration Act Section 1280 through Section 1294.2 of the CCP as
               amended  from  time to  time. The  limitations  with  respect  to
               discovery  set forth above  shall  apply to any such  arbitration
               proceeding.

                    (j) THE PARTIES RECOGNIZE AND AGREE THAT ALL  CONTROVERSIES,
               DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE  PROVISION WILL
               BE DECIDED BY A REFEREE AND NOT BY A JURY,  AFTER  CONSULTING (OR
               HAVING HAD THE  OPPORTUNITY  TO CONSULT) WITH COUNSEL OF ITS, HIS
               OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY,  AND FOR
               THE MUTUAL  BENEFIT OF ALL  PARTIES,  AGREES THAT THIS  REFERENCE
               PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN
               OR AMONG  THEM  ARISING  OUT OF OR IN ANY WAY  RELATED  TO,  THIS
               AGREEMENT OR THE OTHER COMERICA DOCUMENTS.

     3. REPRESENTATIONS AND WARRANTIES. Borrower hereby affirms to Bank, that
all of  Borrower's  representations  and  warranties  set forth in the Agreement
are true, complete and accurate in all respects as of the date hereof.

     4. NO DEFAULTS.  Borrower hereby affirms to Bank that,  after giving effect
to this Amendment,  no Event of Default has occurred and is continuing as of the
date hereof.

     5. CONDITION  PRECEDENT.  The  effectiveness of this Amendment is expressly
conditioned upon receipt by Bank of:

          (a) an executed copy of this Amendment;

          (b)  payment  to  Bank  of  a  commitment   fee  equal  to  $3,000  in
consideration  of this  Amendment;  and

          (c) payment of all of Bank's costs and expenses incurred in connection
with this Amendment.

     6.  COSTS  AND  EXPENSES.   Borrower  shall  pay  to  Bank  all  of  Bank's
out-of-pocket  costs and expenses  arising in connection  with the  preparation,
execution, and delivery of this Amendment and all related documents.

     7.  LIMITED  EFFECT.  In the  event of a  conflict  between  the  terms and
provisions of this Amendment and the terms and provisions of the Agreement,  the
terms and provisions of this Amendment shall govern. In all other respects,  the
Agreement,  as amended and supplemented  hereby,  shall remain in fall force and
effect.

     8. CHOICE OF LAW.  This  Amendment  shall be  governed  by,  construed  and
interpreted in accordance  with the internal laws (and not the law of conflicts)
of the state of California.
