                3.1     BORROWING; ISSUANCE OF BOND; AGREEMENT TO CONSTITUTE
CONTRACT. To provide funds to pay for Project Costs, Issuer hereby agrees to
borrow an amount of up to $1,500,000 from Lender and loan the proceeds of that
borrowing to Borrower. Such borrowing shall only be pursuant to requisitions
submitted by Borrower to Issuer in the form attached hereto as Exhibit C2. As

between Issuer, Borrower and Lender, as holder of the Bond. The parties
covenant that they will abide by the terms of this Agreement and the Bond.

single bond in registered form as set forth in Exhibit B attached hereto. The
Bond shall mature, and Principal of, premium (if any) and Interest on the Bond
shall be payable as set forth herein. A single Bond will be issued to avoid the
execution of individual bonds or promissory notes for each advance by the Lender
to the Issuer for the benefit of the Borrower. The Bond and all obligations of
Issuer under or with respect to the Bond and this Agreement are limited
obligations of Issuer payable solely out of the Loan Payments made by Borrower
for deposit to the Debt Service Fund and other Collateral specifically pledged
hereunder. No recourse shall be had against any other properties, funds or
assets of Issuer for the payment of any amounts owing with respect to the Bond
or this Agreement. The Bond, this Agreement and the obligations of Issuer under
or with respect thereto do not constitute or create a charge against Issuer or
create an indebtedness of Issuer within the meaning of any constitutional debt
limitation. Holders of the Bond shall have no right to compel the payment of any
amounts owing under or with respect to the Bond or this Agreement out of any
funds or other assets of Issuer or the State. Issuer's agents, including the
person(s) executing this Agreement or the Bond, shall not be subject to any
personal liability for any reason relating to the issuance of the Bond or the
performance of any obligations under or with respect to this Agreement.

IN ACCORDANCE WITH RCW 43.163.140(1), THE BOND IS NOT A GENERAL, SPECIAL OR
MORAL OBLIGATION OF THE STATE OR ANY POLITICAL SUBDIVISION THEREOF, NOR A
PLEDGE OF THE FAITH AND CREDIT OF THE STATE OR ANY POLITICAL SUBDIVISION
THEREOF. THE BOND IS A SPECIAL NONRECOURSE REVENUE OBLIGATION OF THE ISSUER,
SECURED BY AND PAYABLE SOLELY FROM THE SPECIAL FUND OR FUNDS CREATED BY THE
ISSUER FOR THEIR REPAYMENT. THE ISSUER HAS NO TAXING POWER.

which will be in an aggregate principal amount of $713,339.49 and will take
place on the date of execution and delivery of this Agreement. The second
installment will be for the balance and will take place on or about November 25,
1997 (but not later than December 1, 1997); provided, however, that the second
installment shall not be funded unless and until Issuer has received a written
statement from Bond Counsel that the average life of the Bond will not be
greater than 120% of the reasonably expected useful life of (1) the assets to be
financed with such installment, and (2) the assets financed with proceeds
derived from the first installment. Borrower hereby agrees, subject to the terms
and conditions of this Agreement, to borrow such amount from Issuer and to pay
all Obligations hereunder. Lender will advance funds necessary to make Loan
installments directly to Borrower pursuant to requisitions submitted by Issuer
and Borrower, which requisitions shall be in the forms of Exhibits C1 and C2
attached hereto. Issuer's obligation to issue the Bond, Lender's obligation to
provide financing for the Loan, and Borrower's obligation to repay the Loan,
shall commence on the date hereof.

hereunder outstanding from time to time shall bear interest (computed on the
basis of actual days elapsed in a 360-day year) as follows. Interest on the
first Loan installment and that portion of the Bond relating thereto shall
accrue from September 30, 1997 at a rate of 10.946%. Interest on the second Loan
installment and that portion of the Bond relating thereto shall accrue from the
date that funds are advanced by Lender to Issuer and loaned by Issuer to
Borrower at an interest rate to be established by Lender of not less than ten
percent (10%) and not greater than twelve percent (12%). Notwithstanding the
foregoing, upon any Determination of Taxability, Interest shall accrue at the
Gross-Up Rate.

interest on the Bond, Issuer assigns to Lender all of Issuer's right to receive
Loan Payments from Borrower hereunder, all of Issuer's rights hereunder (except
for Retained Rights). Lender agrees to accept Loan Payments and other payments
made by Borrower hereunder (and proceeds, if any, of the Collateral) in
satisfaction of Issuer's corresponding obligations on the Bond. No provision,
covenant or agreement contained in this Agreement or any obligation herein
imposed on Issuer, or the breach thereof, shall constitute or give rise to or
impose upon Issuer a pecuniary liability, a charge upon its general credit or a
pledge of its general revenues. Issuer has no taxing power. In making the

claim is based on the willful dishonesty of or intentional violation of law by
such person.

          3.7    PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be made
hereunder shall be stated to be due on a day which is not a Business Day, such

time shall in such case be included in the computation of interest or the fees
hereunder, as the case may be.

with GAAP. If any taxes remain unpaid after the date fixed for the payment
thereof, or if any lien shall be claimed therefor, and such taxes are not being
diligently contested in good faith by the Borrower, then, upon notice to the
Borrower, but on the Borrower's behalf, the Lender may pay such taxes, and the
amount thereof shall be included in the Obligations.

claims, or interests of any Persons, or to effect the purposes of this
Agreement. The Borrower hereby authorizes the Lender to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Borrower where permitted

   17
action and to execute any instrument which the Lender may deem necessary or
advisable to accomplish the purpose of this Agreement, including, without
limitation:

          (a)  to obtain and adjust insurance required to be paid to the Lender
hereunder;

          (b)  upon the occurrence and during the continuance of an Event of

nationally recognized bond counsel to Issuer to the effect that such transfer
and reregistration will not violate the registration requirements of federal or
State securities laws, and (ii) an investment letter in substantially the same

in the Bond to any other person shall be void, and in such event Lender shall
defend, indemnify and hold harmless the Issuer against any claims relating to
any such transfer. In no event shall any transfer of the Bond result in the
Bond being owned by more than one owner. In addition to the foregoing, no such
transfer of the Bond or assignment of this Agreement by Lender shall be
effective unless and until Issuer and Borrower shall have received notice of
the transfer or assignment disclosing the name and address of the assignee or
subassignee. Upon receipt of notice of assignment, Borrower will reflect in a
book entry the assignee designated in such notice of assignment, and shall
agree to make all payments to the assignee designated in the notice of
assignment, notwithstanding any claim, defense, setoff or counterclaim
whatsoever (whether arising from a breach of this Agreement or otherwise) that
Issuer and Borrower may from time to time have against Lender or the assignee.
Borrower agrees to execute all documents, including notices of assignment and
chattel mortgages or financing statements, which may be reasonably requested by
Lender or its assignee to protect their interest in the Collateral and in this
Agreement. Notwithstanding the foregoing, Lender agrees that it will not make
any such assignment or transfer under this section to a direct competitor of
Borrower without Borrower's express written consent.
