          WHEREAS, Seller desires to sell and Buyer desires to purchase the
Securities of Seller (as hereinafter defined) subject to the terms and
conditions set forth in this Agreement;

          NOW, THEREFORE, in consideration of the premises and of the mutual

          1.1  PURCHASE AND SALE OF SECURITIES.  In reliance upon the
representations and warranties made herein and subject to the terms and
conditions hereof, each Buyer intending to be legally bound hereby agrees,
severally, to purchase from Seller and Seller agrees to issue and sell to Buyer
at the Closing (as herein defined) that aggregate principal amount of Seller's
Senior Bridge Debentures due July 1, 1996 (the "Debentures") as set forth
opposite each Buyer's name on Schedule A hereto.

          The Debentures to be sold and purchased at the Closing under this
Agreement are hereinafter sometimes referred to as the "Securities".

          1.2  PURCHASE PRICE AND PAYMENT FOR THE SECURITIES. In consideration
of the sale of the Securities, Buyer agrees that at the Closing, assuming the

available to Buyer are complete and correct.  Seller is duly registered or
qualified to do business as a foreign corporation in the State of Washington and
neither the character or location of the properties owned or leased by Seller
nor the nature of the business transacted by Seller makes registration or
qualification in any other jurisdiction necessary, except where failure to so
qualify would not have a material adverse effect on Seller.

          2.3  AUTHORITY OF SELLER; NO CONFLICTS.

               (a)  Seller has full power and authority to enter into and
perform this Agreement, issue and sell the Securities, and consummate the

Agreement, the Securities will be validly issued, fully paid and nonassessable.
All necessary action, corporate or otherwise, has been taken by Seller to
authorize the execution, delivery, and performance of this Agreement, and the
Agreement is the valid and binding obligation of Seller enforceable in
accordance with its terms.

               (b)  The execution and delivery of this Agreement by Seller does
not, and the issuance of the Securities and the performance of the terms hereof
by Seller will not, constitute a default or event of default under, or violate,
conflict with, or result in any breach of the terms, conditions, or provisions
of:  (i) the corporate charter or By-laws of Seller; (ii) the laws or
regulations of any jurisdiction or any other governmental requirements; or (iii)
any material mortgage, lien, lease, agreement, contract, instrument, order,
arbitration award, injunction, judgment or decision to which Seller is a party
or by which it or its property is bound or materially affected.  Except

permit or other action by, or filing with, any federal, state, or municipal
commission, board, agency or other governmental authority is required in
connection with the execution and delivery by Seller of this Agreement, the
issuance of the Securities, or the consummation of the transaction contemplated
hereby.

               (c)  Unless otherwise indicated in the Disclosure Documents (as

forth in the Disclosure Documents, the issuance and sale of the Securities will
not result in the issuance of, or give rise to any obligation of Seller to issue
any additional shares of capital stock pursuant to any such subscriptions,
warrants, calls, options, rights, commitments or agreements.

               (c)  Except as otherwise stated in the Disclosure Documents (as
defined in Section 2.5 hereof) and except as provided in Exhibit 2.4(c) hereof:
(i) there are no preemptive or similar rights to purchase or otherwise acquire
shares of any class of the capital stock or other securities of Seller pursuant

               (e)  Except for the registration rights granted hereunder and
granted to the purchasers of the Company's 7% Convertible Debentures due
March 31, 2001, and except as otherwise stated in the Disclosure Documents (as
defined in Section 2.5 hereof), no person has any right to cause Seller to
effect the registration under the 1933 Act of any shares of Common Stock or any
other securities (including debt securities) of Seller.

               (f)  All of Seller's stock option plans, and the number of shares
