      terms, is genuine, and fully complies with all applicable laws and
      regulations concerning form, content and manner of preparation and
      execution, and all persons appearing to be obligated on the Collateral
      have authority and capacity to contract and are in fact obligated as they
      appear to be on the Collateral. At the time any Account becomes subject to
      a security interest in favor of Lender, the Account shall be a good and
      valid account representing an undisputed, bona fide indebtedness Incurred
      by the account debtor, for merchandise held subject to delivery

      intangibles, the records concerning the Collateral) at Grantor's address
      shown above or at such other locations as are acceptable to Lender. Upon
      Lender's request, Grantor will deliver to Lender in form satisfactory to

      business, Including the sales of inventory; Grantor shall not remove the
      Collateral from its existing location without Lender's prior written
      consent. To the extent that the Collateral consists of vehicles, or other
      titled property, Grantor shall not take or permit any action which would
      require application for certificates of title for the vehicles outside the
      State of Oregon, without Lender's prior written consent. Grantor shall,
      whenever requested, advise Lender of the exact location of the Collateral.

      Transactions involving Collateral. Except for inventory sold or accounts
      collected in the ordinary course of Grantor's business, or as otherwise
      provided for in this Agreement, Grantor shall not sell, offer to sell, or
      otherwise transfer or dispose of the Collateral, While Grantor is not in
      default under this Agreement, Grantor may sell inventory, but only in the

      of Lender. This Includes security interests even if junior in right to the
      security interests granted under this Agreement. Unless waived by Lender,
      all proceeds from any disposition of the Collateral (for whatever reason)
      shall be held in trust for Lender and shall not be commingled with any

      and marketable title to the Collateral, free and clear of all liens and

      Agreement, upon any promissory note or notes evidencing the indebtedness,
      or upon any of the other Related Documents. Grantor may withhold any such
      payment or may elect to contest any lien if Grantor is in good faith
      conducting an appropriate proceeding to contest the obligation to pay and
      so long as Lender's interest in the Collateral is not jeopardized in
      Lender's sale opinion. If the Collateral is subjected to a lien which is

      interest in the Collateral, in Lender's opinion, is not jeopardized.

      Hazardous Substances. Grantor represents and warrants that the Collateral
      never has been, and never will be so long as this Agreement remains a lien
      on the Collateral, used in violation of any Environmental Laws or for the
      generation, manufacture, storage, transportation, treatment, disposal,

      Maintenance of Casualty insurance. Grantor shall procure and maintain all
      risks insurance, Including without limitation fire, theft and liability
      coverage together with such other insurance as Lender may require with

      the insurer's liability for failure to give such a notice. Each insurance
      policy also shall Include an endorsement providing that coverage in favor
      of Lender will not be impaired in any way by any act, omission or default
      of Grantor or any other person. In connection with all policies covering
      assets in which Lender holds or is offered a security interest, Grantor
      will provide Lender with such loss payable or other endorsements as Lender
      may require, if Grantor at any time fails to obtain or maintain any
      insurance as required under this Agreement, Lender may (but shall not be
      obligated to) obtain such insurance as Lender deems appropriate, Including
      it Lender so chooses "single interest insurance;' which will cover only
      Lender's interest in the Collateral.

      Application of Insurance Proceeds. Grantor shall promptly notify Lender of
      any loss or damage to the Collateral. Lender may make proof of loss if
      Grantor fails to do so within fifteen (15) days of the casualty. All
      proceeds of any insurance on the Collateral, Including accrued proceeds
      thereon, shall be held by Lender as part of the Collateral. If Lender
      consents to repair or replacement of the damaged or destroyed Collateral,
      Lender shall, upon satisfactory proof of expenditure, pay or reimburse
      Grantor from the proceeds for the reasonable cost of repair or
      restoration. If Lender does not consent to repair or replacement of the
      Collateral, Lender shall retain a sufficient amount of the proceeds to pay
      all of the indebtedness, and shall pay the balance to Grantor. Any
      proceeds which have not been disbursed within six (6) months after their
      receipt and which Grantor has not committed to the repair or restoration
      of the Collateral shall be used to prepay the indebtedness.

      Insurance Reserves. Lender may require Grantor to maintain with Lender
      reserves for payment of insurance premiums, which reserves shall be
      created by monthly payments from Grantor of a sum estimated by lender to
      be sufficient to produce, at least fifteen (15) days before the premium
      due date, amounts at least equal to the insurance premiums to be paid. If
      fifteen (15) days before payment is due, the reserve funds are
      insufficient, Grantor shall upon demand pay any deficiency to Lender. The
      reserve funds shall be held by Lender as a general deposit and shall
      constitute a non-interest-bearing account which Lender may satisfy by
      payment of the insurance premiums required to be paid by Grantor as they
      become due. Lender does not hold the reserve funds in trust for Grantor,
      and Lender is not the agent of Grantor for payment of the. Insurance
      premiums required to be paid by Grantor. The responsibility for the
      payment of premiums shall remain Grantor's sole responsibility.

      Insurance Reports. Grantor, upon request of Lender, shall furnish to
      Lender reports on each existing policy of insurance showing such
      information as Lender may reasonably request Including the following: (1)
      the name of the insurer; (2) the risks insured; (2) the amount of the
      policy; (4) the property insured; (5) the then current value on the basis
      of which insurance has been obtained and the manner of determining that
      value; and (6) the expiration date of the policy. In addition, Grantor
      shall upon request by Lender (however not more often than annually) have
      an independent appraiser satisfactory to Lender determine, as applicable,
      the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and except
as otherwise provided below with respect to accounts and above in the paragraph
titled "Transactions Involving Collateral", Grantor may have possession of the
tangible personal property and beneficial use of all the Collateral and may use
it in any lawful manner not Inconsistent with this Agreement or the Related
Documents, provided that Grantor's right to possession and beneficial use shall
not apply to any Collateral where possession of the Collateral by Lender is
required by law to perfect Lender's security interest in such Collateral, Until
otherwise notified by Lender, Grantor may collect any of the Collateral
consisting of accounts. At any time and even though no Event of Default exists,
Lender may exercise its rights to collect the accounts and to notify account
debtors to make payments directly to Lender for application to the indebtedness.
If Lender at any time has possession of any Collateral, whether before or after
an Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any-request
by Grantor shall not of itself be deemed to be a failure to exercise reasonable
care. Lender shall not be required to take any steps necessary to preserve any
rights in the Collateral against prior parties, nor to protect, preserve or
maintain any security interest given to secure the indebtedness.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would
materially affect Lender's interest in the Collateral or if Grantor fails to
comply with any provision of this Agreement or any Related Documents, Including
but not limited to Grantor's failure to discharge or pay when due any amounts
Grantor is required to discharge or pay under this Agreement or any Related
Documents, Lender on Grantor's behalf may (but shall not be obligated to) take
any action that Lender deems appropriate,
<PAGE>
including but not limited to discharging or paying on taxes, liens, security
interests, encumbrances and other claims, at any time levied or placed on the
Collateral and paying all costs for insuring, maintaining and preserving the
Collateral. All such expenditures Incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
Incurred or paid by Lender to the date of repayment by Grantor. All such
expenses will become a part of the indebtedness and, at Lender's option, will
(A) be payable on demand; (B) be added to the balance of the Note and be
apportioned among and be payable with any installment payments to become due
during either (1) the term of any applicable insurance policy; or (2) the
remaining term of the Note; or (C) be treated as a balloon payment which will be
due and payable at the Note's maturity, The Agreement also will secure payment
of these amounts. Such right shall be in addition to all other rights and
remedies to which Lender may be entitled upon Default.

      the Related Documents or to comply with or to perform any term,
      obligation, covenant or condition contained in any other agreement between
      Lender and Grantor.

      False Statements. Any warranty, representation or statement made or
      furnished to Lender by Grantor or on Grantor's behalf under this Agreement
      or the Related Documents is false or misleading in any material respect,
      either now or at the time made or furnished or becomes false or misleading
      at any time thereafter.

      Defective Collateralization. This Agreement or any of the Related
      Documents ceases to be in full force and effect (Including failure of any

      lien) at any time and for any reason.

      Insolvency.  The dissolution or termination of Grantor's existence as a
      going business, the insolvency of Grantor, the appointment of a

      Includes a garnishment of any of Grantor's accounts, Including deposit
      accounts, with Lender. However, this Event of Default shall not apply if
      there is a good faith dispute by Grantor as to the validity or
      reasonableness of the claim which is the basis of the creditor or
      forfeiture proceeding and if Grantor gives Lender written notice of the
      creditor or forfeiture proceeding and deposits with Lender monies or a
      surety bond for the creditor or forfeiture proceeding, in an amount
      determined by Lender, in its sole discretion, as being an adequate reserve
      or bond for the dispute.

      liability under, any Guaranty of the indebtedness.

      financial condition, or Lender believes the prospect of payment or
      performance of the indebtedness is impaired.

      provision of this Agreement within the preceding twelve (12) months, it
      may be cured (and no event of default will have occurred) it Grantor,

      default and thereafter continues and completes all reasonable and
      necessary steps sufficient to produce compliance as soon as reasonably
      practical.

      the Collateral contains other goods not covered by this Agreement at the

      provided that tender makes reasonable efforts to return them to Grantor
      after repossession.

      Sell the Collateral. Lender shall have full power to sell, lease,
      transfer, or otherwise deal with the Collateral or proceeds thereof in
      Lender's own name or that of Grantor. Lender may sell the Collateral at
      public auction or private sale. Unless the Collateral threatens to decline
      speedily in value or is of a type customarily sold on a recognized market,
      Lender will give Grantor, and other persons as required by law, reasonable
      notice of the time and place of any public sale, or the time after which
      any private sale or any other disposition of the Collateral is to be made.

      apply the proceeds, over and above the cost of the receivership, against
      the indebtedness. The receiver may serve without bond if permitted by law.
      Lender's right to the appointment of a receiver shall exist whether or not
      the apparent value of the Collateral exceeds the indebtedness by a
      substantial amount. Employment by Lender shall not disqualify a person
      from serving as a receiver.

      Collect Revenues, Apply Accounts. Lender, either itself or through a
      receiver, may collect the payments, rents, Income, and revenues from the
      Collateral. Lender may at any time in Lender's discretion transfer any
      Collateral into Lender's own name or that of Lender's nominee and receive
      the payments, rents, Income, and revenues therefrom and hold the same as
      security for the indebtedness or apply it to payment of the indebtedness
      in such order of preference as Lender may determine. Insofar as the
      Collateral consists of accounts, general intangibles, insurance policies,
      instruments, chattel paper, chases in action, or similar property, Lender
      may demand, collect, receipt for, settle, compromise, adjust, sue for,
      foreclose, or realize on the Collateral as Lender may determine, whether
      or not indebtedness or Collateral is then due. For these purposes, Lender
      may, on behalf of and in the name of Grantor, receive, open and dispose of
      mail addressed to Grantor; change any address to which mail and payments
      are to be sent; and endorse notes, checks, drafts, money orders, documents
      of title, instruments and items pertaining to payment, shipment, or
      storage of any Collateral. To facilitate collection. Lender may notify
      account debtors and obligors on any Collateral to make payments directly
      to Lender.

      Obtain Deficiency. If Lender chooses to sell any or all of the Collateral.
      Lender may obtain a judgment against Grantor for any deficiency remaining
      on the indebtedness due to Lender after application of all amounts
      received from the exercise of the rights provided in this Agreement.
      Grantor shall be liable for a deficiency even if the transaction described
      in this subsection is a sale of accounts or chattel paper.

      Other Rights and Remedies. Lender shall have all the rights and remedies
      of a secured creditor under the provisions of the Uniform Commercial Code,
      as may be amended from time to time. In addition, Lender shall have and
      may exercise any or all other rights and remedies it may have available at
      law, in equity, or otherwise.

      Election of Remedies. Except as may be prohibited by applicable law, all
      of Lender's rights and remedies, whether evidenced by this Agreement, the
      Related Documents, or by any other writing, shall be cumulative and may be
      exercised singularly or concurrently. Election by Lender to pursue any
      remedy shall not exclude pursuit of any other remedy, and an election to
      make expenditures or to take action to perform an obligation of Grantor
      under this Agreement, after Grantor's failure to perform, shall not affect
      Lender's right to declare a default and exercise its remedies.

submit to the jurisdiction of the courts of the State of Oregon in Multnomah
