        Article V is not then satisfied;

                (ii)    the face amount of the requested Letter of Credit
        exceeds the Available Credit; or

                (iii)   any order, judgment or decree of any Governmental
        Authority or arbitrator of which Issuer is aware shall purport by its
        terms to enjoin or restrain Issuer from issuing such Letter of Credit or
        any Governmental Rule shall prohibit, or request that Issuer refrain
        from, the issuance of letters of credit generally or such Letter of
        Credit in particular or shall impose upon Issuer with respect to such
        Letter of Credit any restriction or reserve or capital requirement (for
        which Issuer is not otherwise compensated) not in effect on the Closing
        Date or result in any loss, cost or expense which (A) was not
        applicable, in effect or known to Issuer on the Closing Date and which
        Issuer in good faith deems material to it, and (B) the reimbursement of
        which is not provided for hereunder.

        (b)     Applicant may request that Issuer issue a Letter of Credit only
by submitting a letter of credit application on Issuer's standard form not later
than 10:00 a.m. (Portland time) at least two Business Days prior to the
requested date of issuance. In no event shall the expiry date of any Letter of
Credit fall after the first anniversary of the Maturity Date. The expiry date
for a standby Letter of Credit may not be more than one year after its date of
issuance, and the expiry date for a commercial (documentary) Letter of Credit
may not be more than 180 days after its date of issuance.

        2.2     REIMBURSEMENT

        (a)     If Issuer makes a payment under a Letter of Credit and is not
reimbursed in the manner contemplated by Section 2.2(b), Applicant shall
reimburse Issuer the amount so paid (even if, under laws applicable to the
rights of the beneficiary of such Letter of Credit, beneficiary's request for
payment was validly presented after expiry of such Letter of Credit) in the
currency expressed in such Letter of Credit, together with interest at the
Applicable Rate from the date Issuer made such payment to the date Applicant
pays such reimbursement. Applicant shall pay such reimbursement in immediately
available funds within three Business Days of Issuer's demand for reimbursement.

                                                                          PAGE 8
<PAGE>

        (b)     Upon issuance of a commercial (documentary) Letter of Credit,
Issuer may exercise its right under Section 3(c) of the Account Control
Agreement and instruct the "Holder" (as defined in the Account Control
Agreement) to invest an amount equal to the face amount of such Letter of Credit
in an U.S. Bank savings account ("Liquid Investment"). Immediately upon a draw
being made under a commercial (documentary) Letter of Credit, Issuer may
instruct the Holder to pay to Issuer from the Liquid Investment an amount
sufficient to reimburse Issuer for the amount paid by Issuer under such draw.

        2.3     FEES; INTEREST

        (a)     Applicant shall pay Issuer the following fees with respect to
standby Letters of Credit, each of which shall be nonrefundable even if a
standby Letter of Credit is terminated or canceled before its stated expiration
date:

                (i)     upon the issuance of a standby Letter of Credit or the
        issuance of an amendment increasing the face amount of a standby Letter
        of Credit, a letter of credit fronting fee equal to the greater of (A)
        $100 or (B) the face amount thereof (or, with respect to an amendment
        increasing the face amount, the increase in the face amount only)
        multiplied by 0.125%;

                (ii)    quarterly, in arrears, on the first Business Day of each
        calendar quarter and upon expiration, surrender or other termination of
        the last standby Letter of Credit outstanding, a letter of credit fee
        equal to the average, aggregate undrawn face amount of all outstanding
        Letters of Credit during the preceding calendar quarter multiplied by
        0.50% per annum; and

                (iii)   upon the occurrence of any other activity with respect
        to a standby Letter of Credit, a fee determined in accordance with
        Issuer's standard fees and charges then in effect for such activity, and
        such fees will be billed by Issuer to Applicant monthly and shall be
        payable in accordance with the terms stated on such billings.

        (b)     Applicant shall pay Issuer fees with respect to commercial
(documentary) Letters of Credit determined in accordance with Issuer's standard
fees and charges then in effect with respect to commercial (documentary) letters
of credit.

        (c)     All amounts payable by Applicant not paid when due shall bear
interest at the Applicable Rate from the date due until paid in immediately
available funds.

        (d)     All interest and per annum fees shall be computed on the basis
of a 360-day year, actual days elapsed.

                                                                          PAGE 9

        2.4     CHANGE OF CIRCUMSTANCES

        (a)     Increased Costs Generally. If any Change in Law shall:

                (i)     impose, modify or deem applicable any reserve, special
        deposit, compulsory loan, insurance charge or similar requirement
        against assets of, deposits with or for the account of, or credit
        extended or participated in by, Issuer;

                (ii)    subject Issuer to any tax of any kind whatsoever with
        respect to this Agreement or any Letter of Credit, or change the basis
        of taxation of payments to Issuer in respect thereof (except for
        Indemnified Taxes or Other Taxes covered by Section 2.5 and the
        imposition of, or any change in the rate of, any Excluded Tax payable by
        Issuer); or

                (iii)   impose on Issuer any other condition, cost or expense
        affecting this Agreement or any Letter of Credit;

and the result of any of the foregoing shall be to increase the cost to Issuer
of issuing or maintaining any Letter of Credit (or of maintaining its obligation
to issue any Letter of Credit), or to reduce the amount of any sum received or
receivable by Issuer hereunder then, upon Issuer's request, Applicant will pay
to Issuer such additional amount as will compensate Issuer for such additional
costs incurred or reduction suffered.

        (b)     Capital Requirements. If Issuer determines that any Change in
Law affecting Issuer or Issuer's holding company regarding capital requirements
has or would have the effect of reducing the rate of return on Issuer's capital
or on the capital of Issuer's holding company as a consequence of this Agreement
or Issuer's commitment to issue Letters of Credit to a level below that which
Issuer or Issuer's holding company could have achieved but for such Change in
Law (taking into consideration Issuer's policies and the policies of Issuer's
holding company with respect to capital adequacy) by an amount Issuer deems to
be material, then from time to time Applicant will pay to Issuer such additional
amount as will compensate Issuer or Issuer's holding company for any such
reduction suffered.

        (c)     Certificates for Reimbursement. A certificate of Issuer setting
forth the amount necessary to compensate Issuer or its holding company, as the
case may be, as specified in Section 2.4(a) or (b) and setting forth in
reasonable detail the basis of the calculation and delivered to Applicant shall
be conclusive absent manifest error. Applicant shall pay Issuer the amount shown
as due on any such certificate within 10 days after receipt thereof.

        (d)     Delay in Requests. Issuer's failure or delay in demanding
compensation pursuant to this Section 2.4 shall not constitute a waiver of
Issuer's right to demand such compensation, provided that Applicant shall not be
required to compensate Issuer pursuant to this Section 2.4 for any increased
costs incurred or reductions suffered more than nine months prior to the date
that Issuer notifies Applicant of the Change in Law giving rise to such
increased costs or reductions and of Issuer's intention to claim compensation
therefor (except that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the nine-month period referred to above shall
be extended to include the period of retroactive effect thereof).

                                                                         PAGE 10
<PAGE>

        2.5     TAXES; PAYMENTS

        (a)     Payments Free of Taxes. Any and all payments by or on account of
any obligation of Applicant under any Letter of Credit Document shall be made
free and clear of and without reduction or withholding for any Indemnified Taxes
or Other Taxes, provided that if Applicant is required by Governmental Rule to
deduct any Indemnified Taxes (including any Other Taxes) from such payments,
then (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.5) Issuer receives an amount equal to the sum it
would have received had no such deductions been made, (ii) Applicant shall make
such deductions and (iii) Applicant shall timely pay the full amount deducted to
the relevant Governmental Authority in accordance with applicable law.

        (b)     Payment of Other Taxes by Applicant. Without limiting the
provisions of Section 2.5(a), Applicant shall timely pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

        (c)     Indemnification by Applicant. Applicant shall indemnify Issuer,
within 10 days after demand therefor, for the full amount of any Indemnified
Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 2.5) paid by
Issuer and any penalties, interest and reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes or Other Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority.
A certificate as to the amount of such payment or liability delivered to
Applicant by Issuer shall be conclusive absent manifest error.

        (d)     Evidence of Payments. As soon as practicable after any payment
of Indemnified Taxes or Other Taxes by Applicant to a Governmental Authority,
Applicant shall deliver to Issuer the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the
return reporting such payment or other evidence of such payment reasonably
satisfactory to Issuer.

        (e)     Reversal of Payments. If after receipt of any payment of any of
the Obligations or application of the proceeds of any collateral to any of the
Obligations Issuer is required to surrender or return such payment or proceeds
to any Person for any reason, then the Obligations intended to be satisfied by
such payment or application of proceeds shall be reinstated and continue and
this Agreement shall continue in full force and effect as if such payment or
application of proceeds had not been received or applied by Issuer. Applicant
hereby indemnifies and holds Issuer harmless for the amount of any such payments
or proceeds surrendered or returned. This Section 2.5 shall remain effective
notwithstanding any contrary action which may be taken by Issuer in reliance
upon such payment or proceeds. This Section 2.5 shall survive the payment in
full and performance of all of Applicant's other Obligations.

                                                                         PAGE 11
<PAGE>

        2.6     DUTY TO MITIGATE

        If Issuer claims any additional amount payable pursuant to either
Section 2.4 or Section 2.5, Issuer, at Applicant's expense, shall use reasonable
efforts (consistent with Governmental Rules) to file any certificate or document
reasonably requested by Applicant if the making of such filing would avoid the
need for, or reduce the amount of, any such additional amounts that may
thereafter accrue or avoid the circumstances giving rise to such additional
amounts and would not, in the sole determination of Issuer, require it to incur
additional costs or be otherwise disadvantageous to Issuer.

which representations and warranties shall survive the execution of this

Fees) incurred by Issuer in connection with the enforcement or protection of its
rights in connection with the Letter of Credit Documents and the Obligations,
including those incurred during any workout, restructuring or negotiations in

        (b)     Indemnification by Applicant. Applicant shall indemnify Issuer
(and any sub-agent thereof) and each Related Party of Issuer (each such Person
being called an "Indemnitee") against, and hold each Indemnitee harmless from,
any and all losses, claims, damages, liabilities and related expenses (including
Legal Fees) incurred by any Indemnitee or asserted against any Indemnitee by any

whether based on contract, tort or any other theory, whether brought by a third
party or by Applicant, and regardless of whether any Indemnitee is a party
thereto, provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (y) result from a claim brought by
Applicant against an Indemnitee for breach in bad faith of such Indemnitee's
obligations under any Letter of Credit Document, if Applicant has obtained a
final and nonappealable judgment in its favor on such claim as determined by a
court of competent jurisdiction.

Document or any agreement or instrument contemplated thereby, the transactions
contemplated thereby or the use any Letter of Credit.

        The Letter of Credit Documents shall be binding upon and inure to the
benefit of the successors and assigns of the parties; provided, however, that

in all or any part of, or any interest in, Issuer's rights and benefits under

withheld or delayed), to any bank, financial institution or institutional
lender.

        No failure on the part of Issuer to exercise, and no delay in
exercising, any right, power, privilege or remedy under any Letter of Credit
Document shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right, power, privilege or remedy preclude any other or
further exercise thereof or the exercise of any other right, power, privilege or
remedy. The rights and remedies under the Letter of Credit Documents are
cumulative and not exclusive of any rights, powers, privileges and remedies that

or special, time or demand, provisional or final, in whatever currency) at any
time held and other obligations (in whatever currency) at any time owing by
Issuer or any such affiliate to or for the credit or the account of Applicant
against any and all of the Obligations, irrespective of whether or not Issuer
shall have made any demand under any Letter of Credit Document and although such
Obligations may be contingent or unmatured. The rights of Issuer and its
affiliates under this Section 8.5 are in addition to other rights and remedies
(including other rights of setoff) that Issuer or its affiliates may have.
Issuer shall endeavor to notify Applicant promptly after any such setoff and
application, provided that the failure to give such notice shall not affect the
validity of such setoff and application.

                                                                         PAGE 22

relating to the subject matter hereof. This Agreement shall become effective
when it has been executed by Issuer and when Issuer shall have received
counterparts hereof that, when taken together, bear the signatures of each of
the other parties hereto.

benefit of the parties hereto and their respective permitted successors and
assigns, and no other person or entity shall be a third party beneficiary of, or
have any direct or indirect cause of action or claim in connection with, this
Agreement or any other of the Letter of Credit Documents to which it is not a
party.

        8.8     TIME

        Time is of the essence of each and every provision of this Agreement and
each other of the Letter of Credit Documents.

under applicable law, such provision shall be ineffective only to the extent of
such prohibition or invalidity without invalidating the remainder of such
provision or any remaining provisions of this Agreement.

        8.10    CONFIDENTIALITY

        Issuer agrees to maintain the confidentiality of the Information (as
defined below), except that Information may be disclosed (a) to its affiliates

party hereto, (e) in connection with the exercise of any remedies under any Loan

enforcement of rights thereunder, (f) subject to an agreement containing

                                                                         PAGE 23

assignee of or participant in, or any prospective assignee of or participant in,
any of its rights or obligations under this Agreement or (ii) any actual or
prospective counterparty (or its advisors) to any swap or derivative transaction
relating to Applicant and its obligations, (g) with the consent of Applicant or
(h) to the extent such Information (x) becomes publicly available other than as
a result of a breach of this Section 8.10 or (y) becomes available to Issuer or
any of its affiliates on a nonconfidential basis from a source other than
Applicant.

        For purposes of this Section 8.10, "Information" means all information
received from Applicant relating to Applicant or its business, other than any
such information that is available to Issuer on a nonconfidential basis prior to
disclosure by Applicant, provided that, in the case of information received from
Applicant after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section 8.10 shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

        Notwithstanding anything herein to the contrary, "Information" shall not
include, and Issuer may disclose to any and all Persons, without limitation of
any kind, (a) any information with respect to the U.S. federal and state income
tax treatment of the transactions contemplated hereby and any facts that may be
relevant to understanding such tax treatment, which facts shall not include for
this purpose the names of the parties or any other Person named herein, or
information that would permit identification of the parties or such other
Persons, or any pricing terms or other nonpublic business or financial
information that is unrelated to such tax treatment or facts, and (b) all
materials of any kind (including opinions or other tax analyses) that are
provided to Issuer relating to such tax treatment or facts.

        8.11    GOVERNING LAW

        This Agreement shall be governed by and construed in accordance with the
laws of the State of Oregon, excluding any conflicts of law rule or principle
that might otherwise refer construction or interpretation of this Agreement to
the substantive law of another jurisdiction.
