     B.   The Secured Party and the Debtor have entered into the Sublease
pursuant to which the Debtor is leasing the Leased Premises (as defined in the
Sublease) from the Secured Party.

     C.   The Loan and the Debtor's obligations under the Sublease are to be
secured by, among other things, this Security Agreement, creating a first

Secured Party and contained in the Sublease; and (iii) performance and discharge

     NOW THEREFORE, in consideration of the Loan and the Sublease and in order
to induce the Secured Party to make the Loan and enter into the Sublease, the
parties agree as follows:

     1.   For valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Debtor and Nation hereby convey, assign, transfer and
grant to the Secured Party a first priority security interest in all of their
present right and hereafter acquired right, title and interest in and to the
following (collectively, the "Collateral"):

     a.   all present and hereafter acquired equipment owned by the Debtor in
          all of its forms and wherever located

     b.   any and all machinery, equipment, controls, attachments, parts, tools,
          furniture and furnishings used in the conduct of the Enterprise, and
          all attachments, accessories, accessions, replacements, substitutions,
          additions and improvements to any of the foregoing (the property in a.
          and b. being referred to collectively herein as the "Equipment");

     c.   all insurance proceeds (including but not limited to proceeds of
          insurance and refunds of unearned premiums) due or to become due to
          Debtor or 

 
          Nation under, and all other rights of Debtor or Nation under or with
          respect to, any and all policies of insurance covering all or any
          portion of the Property, the Facility, the Leased Premises, and/or the
          Equipment;

     d.   all Available Distributable Cash; and

     e.   all proceeds and products of the foregoing, including but not limited
          to accounts, general intangibles, equipment, inventory, money, deposit
          accounts, goods, chattel paper, documents, instruments and insurance
          proceeds, all refunds, equities, benefits, book equities, returns,
          credits, revolving fund withholdings, return of capital and
          certificates evidencing any right to receive payment in any form from
          any marketer of goods or inventory and any other tangible or
          intangible property received upon the sale, lease, transfer or other
          disposition of any of the foregoing.

     2.   The Debtor warrants and represents to Secured Party that:

     a.   Debtor and Nation are the true and lawful owners of the Collateral and
          have good and valid title to the Collateral free and clear from any
          and all liens, security interests, encumbrances or other rights, title
          or interest of any other person, firm or corporation, excepting the
          rights and interest of the Secured Party hereunder.  The Equipment has
          been delivered to and accepted and installed by the Debtor, and is in
          good working order.  The Equipment is all of the equipment used in the
          conduct of the Enterprise.

     b.   The Collateral is not subject to any other lien or security interests
          (including, without limitation, "blanket" security interests).

     c.   The Debtor shall defend the Secured Party's interest in the Collateral
          against all claims and demands of all or any other persons at any time
          claiming the same or any interest therein adverse to the Secured
          Party.

     d.   There are no actions at law, suits in equity, or proceedings before
          any governmental agency, commission, bureau or tribunal or any
          arbitration proceedings that if adversely determined would adversely
          affect the present condition, financial or otherwise, of the
          Collateral or would adversely affect the right of the Debtor to pledge
          and assign all or any part of the Collateral or rights and security
          afforded Secured Party hereunder.

     e.   The Equipment is and will be used for the business purpose of
          equipping the Enterprise located within the Facility.  The Collateral
          will at all times be located at the Property.

     f.   The Debtor will keep the Collateral insured at all times against loss
          by fire and/or other hazards concerning which, in the judgment of the
          Secured Party, insurance protection is reasonably necessary, in a
          company or companies reasonably satisfactory to the Secured Party and
          in amounts sufficient to protect Secured Party against loss or damage
          to said Collateral and will pay the premiums therefore; such policy or
          policies of insurance will be delivered to and held by the Secured
          Party, together with loss payable clauses in favor of the Secured
          Party as its interest may appear, in form satisfactory to the Secured
          Party; and Secured Party may act as attorney for Debtor in obtaining,
          adjusting, settling and canceling such 

                                      -2-

 
          insurance and endorsing any drafts.

     g.   The Debtor will keep the Equipment in good condition and repair,
          reasonable wear and tear excepted.  The Debtor will permit Secured
          Party to enter upon any lands owned, leased or otherwise controlled by
          or on behalf of the Debtor at reasonable times for the purpose of
          examining the Collateral, subject to the security requirements of the
          Enterprise.

     h.   The Debtor will pay as part of the Indebtedness Secured Hereby all
          amounts, including reasonable attorneys' fees and legal expenses, with
          interest thereon, paid by Secured Party (a) for taxes, levies,
          insurance, repairs to, or maintenance of the Collateral, and (b) in
          taking possession of, disposing of or preserving the Collateral after
          any default hereinafter described.

     i.   Debtor will not without the prior written consent of Secured Party (a)
          permit any liens or security interests (other than the security
          interest granted hereby) to attach to any of the Collateral; (b)
          permit any of the Collateral to be levied upon or attached by legal
          process; (c) except as permitted by the Loan Agreement, sell or offer
          to sell or otherwise transfer the Collateral; (d) do or permit
          anything to be done that may impair the value of the Collateral; or
          (e) except as permitted by the Loan Agreement, remove or permit the
          Collateral to be removed from the Property.

     j.   If any of the Collateral is or is to become a fixture, the Debtor
          agrees to furnish Secured Party, at its request, with a statement or
          statements signed by all persons who have or claim an interest in the
          real estate concerned, which statements shall provide that the signer
          consents to the security interest created hereby and disclaims any
          interest in the Collateral as fixtures.

     k.   Debtor acknowledges that the Equipment is of the design, capacity and
          manufacture specified for and by the Debtor and that Debtor is
          satisfied that the same is suitable for its intended purposes.  Debtor
          further acknowledges and agrees that Secured Party is not a
          manufacturer or vendor of the Equipment and that Secured Party has not
          made, and does not make, any representation, warranty or covenant with
          respect to merchantability, fitness for any purpose, condition,
          quality, delivery, installation, durability, patent, copyright or
          trademark infringement, suitability or capability of any item of
          Equipment in any respect or in connection with any other purpose or
          use of Debtor, or any other representation, warranty or covenant of
          any kind or character expressed or implied with respect thereto.
          Debtor accordingly agrees not to assert any claim whatsoever against
          Secured Party based thereon.  Secured Party shall have no obligation
          to install, erect, test, adjust or service the Equipment.  Debtor
          shall look to the manufacturer or vendor for any claims related to the
          Equipment.

     l.   Debtor shall provide Secured Party with sixty (60) days' prior written
          notice of any change in its name or the location of its principal
          offices.

     m.   The Debtor will derive economic benefit from the Loan and the
          Sublease, and the Debtor acknowledges that Secured Party is relying
          upon the security interests granted herein and in the remaining
          Collateral Agreements 

                                      -3-

 
          in making the Loan.

     3.   This Agreement constitutes a Security Agreement under the Uniform
Commercial Code (the "UCC") as in effect in the State of Washington.

4.   a.   Debtor shall give prompt written notice to Secured Party of any
          damage or injury to the Property, the Facility, the Leased Premises
          and/or the Equipment or of any loss or diminution in value thereof,
          and Debtor shall give whatever notice to insurers of any such damage,
          injury, loss or diminution of value as may be required.  All insurance
          proceeds of the Property, the Facility, the Leased Premises and/or the
          Equipment and all causes of action, claims, compensation, awards and
          recoveries for any damage or injury to the Property, the Facility, the
          Leased Premises and/or the Equipment or for any loss or diminution in
          value of the Property, the Facility, the Leased Premises and/or the
          Equipment are hereby assigned to and shall be paid to Secured Party,
          and Debtor agrees to execute such further evidence of such assignment
          of such insurance proceeds, causes of action, claims, compensation,
          awards and recoveries as Secured Party may require.  Secured Party may
          (but shall not be obligated to) participate in any suits or
          proceedings relating to any such proceeds, causes of action, claims,
          compensation, awards or recoveries and may join with Debtor in
          adjusting any loss covered by insurance.  Debtor hereby directs the
          issuer of any such policy to pay any such money directly to Secured
          Party.  Both before and after the occurrence of an Event of Default
          (defined below), Secured Party may (but need not) in Secured Party's
          own name or in Debtor's name, execute and deliver proofs of claim,
          receive all such money, endorse checks and other instruments
          representing payment of such money and adjust, litigate, compromise or
          release any claim against the issuer of any such policy.
 
     b.   In the event of loss, Secured Party is hereby authorized either (a) to
          settle, adjust or compromise any claim under the above insurance
          policies without consent of Debtor, which consent is hereby expressly
          waived; or (b) to allow Debtor to agree with the insurance company or
          companies on the amount to be paid upon the loss.  In either case,
          Secured Party is authorized to collect and receive any such insurance
          money.  Notwithstanding anything to the contrary contained herein,
          Debtor may, without the consent of Secured Party, so long as Debtor is
          not in default hereunder, settle, adjust or compromise any claim in an
          original amount less than Fifty Thousand Dollars ($50,000).

     c.   Notwithstanding anything to the contrary herein contained, if (i) the
          insurers do not deny liability as to the original amount of the claim;
          (ii) no Event of Default exists and no event exists that, with the
          passage of time or the giving of notice or both, would constitute such
          an Event of Default; (iii) Secured Party has received evidence,
          reasonably satisfactory to Secured Party in its sole discretion, that
          there are sufficient funds available and/or committed, including such
          insurance proceeds, to effectuate a restoration and to cover the
          expenses of operating and maintaining the Property, the Facility, the
          Leased Premises and/or the Equipment, (iv) Secured Party has
          reasonably approved the plans and specifications to be used in
          connection with such restoration; and (v) the restoration will be
          completed within one (1) year (and in any event prior to the last day
          of the seventy-eighth (78th) 

                                      -4-

 
          month following the Commencement Date) and will return the Property,
          the Facility, the Leased Premises and/or the Equipment to
          substantially the same condition, character and utility and to at
          least the value that existed immediately prior to such casualty; then
          such insurance proceeds shall be used to pay Debtor for the cost of
          rebuilding, replacing, restoring or repairing the Property, the
          Facility, the Leased Premises and/or the Equipment so insured in
          accordance with the disbursement procedures herein contained. The 31
          day time period set forth in Section 3(b) of the Note shall be
          extended by the number of days in which the Enterprise is not
          operational as a consequence of such restoration. In all other cases,
          such insurance proceeds may at Secured Party's discretion, either be
          applied in payment or reduction of the Indebtedness Secured Hereby
          (whether then due or not) or be held by Secured Party and used to
          reimburse Debtor or any other party for the cost of the rebuilding,
          replacing, restoring or repairing the Property, the Facility, the
          Leased Premises and/or the Equipment so insured.

     d.   In the event Debtor is entitled (whether pursuant to the terms hereof
          or pursuant to Secured Party's election or otherwise) to payment out
          of insurance proceeds for any repair, rebuilding, restoration or
          replacement, such proceeds shall be made available, from time to time,
          upon Secured Party being furnished with satisfactory evidence of
          progress in such repair, rebuilding, restoration or replacement,
          together with satisfactory evidence of the estimated cost of
          completion thereof and together with any such architect's
          certificates, waivers of lien, contractors' sworn statements and other
          evidence of cost and payments as Secured Party may require and
          approve.  If the estimated cost of the work exceeds ten percent (10%)
          of the original principal amount of the indebtedness secured hereby,
          Secured Party shall also be furnished with all plans and
          specifications for such rebuilding, replacement, restoration or repair
          as Secured Party may require and reasonably approve.  At all times the
          undisbursed balance of said proceeds remaining in the hands of Secured
          Party shall be at least sufficient to pay for the cost of completion
          of the work free and clear of liens.  Any surplus that may remain out
          of said insurance proceeds after payment of such cost of repair,
          rebuilding, restoration or replacement shall, at the option of Secured
          Party, be applied on account of the Indebtedness Secured Hereby
          (whether then due or not).

     5.   Upon the occurrence of an Event of Default and or any event that, with
the passage of time or the giving of notice or both, would constitute such an
Event of Default, Secured Party may require Debtor to establish a cash
management and depositary arrangement acceptable to Secured Party in its sole
and absolute discretion pursuant to which, among other things, (i) the
depositary bank shall enter into an agreement in form and substance acceptable
to Secured Party in its sole and absolute discretion acknowledging Secured
Party's first priority security interest in the Available Distributable Cash and
waiving all set off, banker's lien and similar rights, (ii) Debtor shall cause
all revenues of the Enterprise to be transferred to such depositary bank
pursuant thereto, and (iii) the parties shall agree as to use of revenues from
the Enterprise for the Debtor's continued operation of the Enterprise
(including, without limitation, the continued payment of normal and necessary
operating expenses thereof).

     6.   Upon one (1) day's written notice, Debtor shall make available for
inspection and copying by Secured Party all present and future books, records,
accounting 

                                      -5-

 
logs and stored data pertaining to the Collateral or to the Enterprise,
including, without limitation, computer programs, software and the equipment
containing said books, records, accounting logs and stored data.

     7.    (a) Upon the occurrence and during the continuance of an Event of
Default, the Secured Party or its designee may without demand, advertisement or
notice of any kind (except such notice as may be required under the UCC) all of
which are, to the extent permitted by law, hereby expressly waived:

     (i)   Exercise any of the remedies available to a secured party under the
           UCC or other applicable law;

     (ii)  Proceed immediately to exercise each and all of the powers, rights,
           and privileges reserved or granted to Secured Party hereunder and
           under the Note and the Sublease and the other Loan Documents and the
           Transaction Documents;

     (iii) Proceed to protect and enforce this Security Agreement by suits or
           proceedings or otherwise, and for the enforcement of any other legal
           or equity available to Secured Party; and/or

     (iv)  Realize upon the Collateral and hold, own or dispose of the same as
           its own property to the extent permitted pursuant to Applicable Law.

           (b) Upon the occurrence of an Event of Default the Debtor shall make
the Collateral available to Secured Party or its designee at a place to be
designated by Secured Party or its designee which is reasonably convenient, and
authorizes Secured Party or its designee to enter the Property and/or the
Facility to assemble, possess, store and sell the Collateral.  Debtor further
agrees to pay all costs and expenses of Secured Party or its designee, including
reasonable attorneys' fees, in the enforcement of any of Secured Party's rights
hereunder.  If any notice of sale, disposition or other intended action by
Secured Party or its designee is required by law to be given to Debtor, such
notice shall be deemed reasonably and properly given if mailed to Debtor at the
notice address specified in accordance with the Loan Agreement at least ten (10)
days before such sale, disposition or other intended action.  Waiver of any
default hereunder by Secured Party shall not be waiver of any other default or
of a same default on any other occasion.  No delay or failure by Secured Party
to exercise any right or remedy shall be a waiver of such right or remedy and no
single or partial exercise by Secured Party of any right or remedy shall
preclude other or further exercise thereof or the exercise of any other right or
remedy at any other time.

     8.    Debtor agrees to execute such financing statements or other
instruments as may be required under the UCC or similar state, federal or tribal
laws to perfect the security interest hereunder and shall from time to time at
Debtor's expense execute and deliver such assignments and endorsements and file
such additional financing statements or other instruments as may be required to
create and continue to perfect the security interest intended to be created
herein.  Debtor hereby authorizes Secured Party at Debtor's expense, to do all
reasonable acts and things which Secured Party may deem necessary to perfect and
continue perfected the security interest created by this Security Agreement and
to protect the Collateral.

     9.    This Security Agreement shall be governed by federal law, if
applicable, then by the laws of the State of Washington.

                                      -6-

 
     10.  Without in any way limiting the waiver of sovereign immunity contained
herein, the Nation and the Debtor expressly authorize any governmental or other
agency authorities who have the right and duty under Applicable Law to take any
and all action authorized or ordered by any court, including without limitation,
entering Indian land within the Nation's jurisdiction for the purpose of
repossessing the Collateral or otherwise giving effect to any judgment entered.
It is the intent of the parties that the Secured Party or its designee will be
able to obtain possession of the Collateral in accordance with the rights
afforded it under applicable laws and/or any court order.

     11.  This Security Agreement and each and every covenant and agreement and
other provisions hereunder shall be binding upon the Debtor and its successors
and assigns and shall inure to the benefit of Secured Party and its successors
and assigns.

     12.  Any unenforceability or invalidity of any provision hereof shall not
render any other provision or provisions herein contained unenforceable or
invalid.

     13.  Debtor hereby waives its sovereign immunity from suit and consents to
jurisdiction to the extent provided and as limited in the Loan Agreement.

     14.  Any notice any party may hereto desire may be required to give to any
other party shall be sent in accordance with the Loan Agreement.

     IN WITNESS WHEREOF, the undersigned have caused this Security Agreement to
be duly executed as of the date first above written.
