follows ("General Release"):

                  (a) Borrower,  for itself and on behalf of its  successors and
assigns,  does hereby release,  acquit and forever discharge Bank, all of Bank's
predecessors  in  interest,  and  all  of  Bank's  past  and  present  officers,
directors, attorneys,  affiliates, employees and agents, of and from any and all
claims, demands, obligations,  liabilities,  indebtedness, breaches of contract,
breaches  of  duty  or  of  any  relationship,  acts,  omissions,   misfeasance,
malfeasance,  causes  of  action,  defenses,  offsets,  debts,  sums  of  money,
accounts,  compensation,  contracts,  controversies,  promises,  damages, costs,
losses and expenses,  of every type,  kind,  nature,  description  or character,
whether known or unknown, suspected or unsuspected,  liquidated or unliquidated,
each as though fully set forth herein at length  (each,  a "Released  Claim" and
collectively, the "Released Claims"), that Borrower now has or may acquire as of
the  later  of:  (i) the date  this  Amendment  becomes  effective  through  the
satisfaction  (or waiver by Bank) of all conditions  hereto;  (ii) the date that
Borrower has executed  and  delivered  this  Amendment to Bank  (hereafter,  the
"Release Date"), including without limitation,  those Released Claims in any way
arising  out  of,  connected  with  or  related  to any  and  all  prior  credit
accommodations,  if any,  provided  by Bank,  or any of Bank's  predecessors  in
interest,  to  Borrower,  and any  agreements,  notes or  documents  of any kind
related thereto or the transactions contemplated thereby or hereby, or any other
agreement or document referred to herein or therein.

                  (b) Borrower hereby  acknowledges,  represents and warrants to
Bank that it agrees to assume the risk of any and all unknown,  unanticipated or
misunderstood  defenses and Released Claims which are released by the provisions
of this  General  Release  in favor of Bank,  and  Borrower  hereby  waives  and
releases all rights and benefits  which it might  otherwise have under any state
or  local  laws  or  statutes  with  regard  to the  release  of  such  unknown,
unanticipated or misunderstood defenses and Released Claims.

                  (c)  Each   person   signing   below  on  behalf  of  Borrower
acknowledges  that he or she has read  each of the  provisions  of this  General
Release.  Each such  person  fully  understands  that this  General  Release has
important  legal  consequences,  and each  such  person  realizes  that they are
releasing  any and all Released  Claims that Borrower may have as of the Release
Date.  Borrower hereby  acknowledges  that it has had an opportunity to obtain a
lawyer's advice  concerning the legal  consequences of each of the provisions of
this General Release.

                  (d) Borrower hereby specifically acknowledges and agrees that:
(i) none of the  provisions  of this  General  Release  shall be construed as or
constitute an admission of any


                                      -3-


liability on the part of Bank; (ii) the provisions of this General Release shall
constitute an absolute bar to any Released  Claim of any kind,  whether any such
Released  Claim is based on  contract,  tort,  warranty,  mistake  or any  other
theory, whether legal, statutory or equitable; and (iii) any attempt to assert a
Released  Claim barred by the  provisions of this General  Release shall subject
Borrower to the  provisions of applicable law setting forth the remedies for the
bringing of groundless, frivolous or baseless claims or causes of action.

                  7. Miscellaneous.  Except as specifically provided herein, all
terms and  conditions  of the Credit  Agreement  shall  remain in full force and
effect,  without  waiver  or  modification.  All  terms  defined  in the  Credit
Agreement  shall  have  the  same  meaning  when  used in this  Amendment.  This
Amendment and the Credit Agreement shall be read together, as one document. This
Amendment  may be  executed  in any number of  counterparts,  each of which when
executed and delivered shall be deemed to be an original,  and all of which when
taken together shall constitute one and the same Amendment.

                  8. Reaffirmation;  Certification.  Borrower hereby remakes all
representations  and warranties  contained in the Credit Agreement and reaffirms
all covenants set forth therein.  Borrower further certifies that as of the date
of this  Amendment  there  exists no Event of  Default  as defined in the Credit
Agreement,  nor any  condition,  act or event which with the giving of notice or
the passage of time or both would constitute an Event of Default.

UNDER OREGON LAW, MOST  AGREEMENTS,  PROMISES AND COMMITMENTS MADE BY BANK AFTER
OCTOBER 3, 1989 CONCERNING  LOANS AND OTHER CREDIT  EXTENSIONS WHICH ARE NOT FOR
PERSONAL,  FAMILY OR  HOUSEHOLD  PURPOSES  OR SECURED  SOLELY BY THE  BORROWER'S
RESIDENCE MUST BE IN WRITING,  EXPRESS CONSIDERATION AND BE SIGNED BY BANK TO BE
ENFORCEABLE.

                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Amendment to be executed as of the day and year first written above.
