08-01-1997                         (CONTINUED)                          PAGE 2
LOAN NO 2009701
================================================================================


     PERFECTION OF SECURITY INTEREST. Grantor agrees to execute such financing
     statements and to take whatever other actions are requested by Lender to
     perfect and continue Lender's security interest in the Collateral. Upon
     request of Lender, after an event of default, Grantor will deliver to
     Lender any and all of the documents evidencing or constituting the
     Collateral, and Grantor will note Lender's interest upon any and all
     chattel paper if not delivered to Lender for possession by Lender. Grantor
     hereby appoints Lender as its irrevocable attorney-in-fact for the purpose
     of executing any documents necessary to perfect or to continue the security
     interest granted in this Agreement. Lender may at any time, and without
     further authorization from Grantor, file a carbon, photographic or other
     reproduction of any financing statement or of this Agreement for use as a
     financing statement. Grantor will reimburse Lender for all reasonable
     expenses for the perfection and the continuation of the perfection of
     Lender's security interest in the Collateral. Grantor promptly will notify
     Lender before any change in Grantor's name including any change to the
     assumed business names of Grantor.

     NO VIOLATION. The execution and delivery of this Agreement will not violate
     any law or agreement governing Grantor or to which Grantor is a party, and
     its certificate or articles of incorporation and bylaws do not prohibit any
     term or condition of this Agreement.

     ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of
     accounts, chattel paper, or general intangibles, the Collateral is
     enforceable in accordance with its terms, is genuine, and complies with
     applicable laws 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.

     REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the extent
     the Collateral consists of intangible property such as accounts, the
     records concerning the Collateral) at Grantor's address shown above, or at
     such other locations as are acceptable to Lender. Except in the ordinary
     course of its business, including the sales of inventory, Grantor shall not
     remove the Collateral from its existing locations without the prior written
     consent of Lender.

     TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts
     collected in the ordinary course of Grantor's business, Grantor shall not
     sell, offer to sell, or otherwise transfer or dispose of the Collateral.
     Grantor shall not pledge, mortgage, encumber or otherwise permit the
     Collateral to be subject to any lien, security interest, encumbrance, or
     charge, other than the security interest provided for in this Agreement,
     without the prior written consent 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 other funds; provided however, this
     requirement shall not constitute consent by Lender to any sale or other
     disposition. Upon receipt, Grantor shall immediately deliver any such
     proceeds to Lender.

     TITLE. Grantor represents and warrants to Lender that it holds good and
     marketable title to the Collateral, free and clear of all liens and
     encumbrances except for the lien of this Agreement. No financing statement
     covering any of the Collateral is on file in any public office other than
     those which reflect the security interest created by this Agreement or to
     which Lender has specifically consented. Grantor shall defend Lender's
     rights in the Collateral against the claims and demands of all other
     persons.

     COLLATERAL SCHEDULES AND LOCATIONS. Insofar as the Collateral consists of
     equipment, Grantor shall deliver to Lender, as often as Lender shall
     require, such lists, descriptions, and designations of such Collateral as
     Lender may require to identify the nature, extent, and location of such
     Collateral. Such information shall be submitted for Grantor and each of its
     subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all
     tangible Collateral in good condition and repair. Grantor will not commit
     or permit damage to or destruction of the Collateral or any part of the
     Collateral. Lender and its designated representatives and agents shall have
     the right at all reasonable times to examine, inspect, and audit the
     Collateral wherever located. Grantor shall immediately notify Lender of all
     cases involving the return, rejection, repossession, loss or damage of or
     to any Collateral; of any request for credit or adjustment or of any other
     dispute arising with respect to the Collateral; and generally of all
     happenings and events affecting the Collateral or the value or the amount
     of the Collateral. The amount for notification is $150,000.00.

     TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes,
     assessments and liens upon the Collateral, its use or operation, upon this
     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 sole opinion. If the Collateral is subjected to a lien which is
     not discharged within fifteen (15) days, Grantor shall deposit with Lender
     cash, a sufficient corporate surety bond or other security satisfactory to
     Lender in an amount adequate to provide for the discharge of the lien plus
     any interest, costs, attorneys' fees or other charges that could accrue as
     a result of foreclosure or sale of the Collateral. In any contest Grantor
     shall defend itself and Lender and shall satisfy any final adverse judgment
     before enforcement against the Collateral. Grantor shall name Lender as an
     additional obligee under any surety bond furnished in the contest
     proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly,
     in all material respects, with all laws, ordinances, rules and regulations
     of all governmental authorities, now or hereafter in effect, applicable to
     the ownership, production, disposition, or use of the Collateral. Grantor
     may contest in good faith any such law, ordinance or regulation and
     withhold compliance during any proceeding, including appropriate appeals,
     so long as Lender's 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 for the generation, manufacture, storage,
     transportation, treatment, disposal, release or threatened release of any
     hazardous waste or substance, as those terms are defined in the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the Superfund
     Amendments and Reauthorization Act of 1986, Pub. L. No. 90-499 ("SARA"),
     the Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et
     seq., the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901,
     et seq., or other applicable state or Federal laws, rules, or regulations
     adopted pursuant to any of the foregoing. The terms "hazardous waste" and
     "hazardous substance" shall also include, without limitation, petroleum and
     petroleum by-products or any fraction thereof and asbestos. The
     representations and warranties contained herein are based on Grantor's due
     diligence in investigating the Collateral for hazardous waste and
     substances. Grantor hereby (a) releases and waives any future claims
     against Lender for indemnity or contribution in the event Grantor becomes
     liable for cleanup or other costs under any such laws, and (b) agrees to
     indemnify and hold harmless Lender against any and all claims and losses
     resulting from a breach of this provision of this Agreement. This
     obligation to indemnify shall survive the payment of the Indebtedness and
     the satisfaction of this Agreement.

     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
     respect to the Collateral, in form, amounts, coverages and basis reasonably
     acceptable to Lender and issued by a company or companies reasonably
     acceptable to Lender. Grantor, upon request of Lender, will deliver to
     Lender from time to time the policies or certificates of insurance in form
     satisfactory to Lender, including stipulations that coverages will not be
     cancelled or diminished without at least ten (10) days' prior written
     notice to Lender and not including any disclaimer of the Insurer's
     liability for failure to give such a notice. Each insurance policy also
     shall include

                          COMMERCIAL SECURITY AGREEMENT
08-01-1997                         (CONTINUED)                          PAGE 3

================================================================================


     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 if it 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 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: (a) the name of the
     insurer; (b) the risks insured; (c) the amount of the policy; (d) the
     property insured; (e) the then current value on the basis of which
     insurance has been obtained and the manner of determining that value; and
     (f) the expiration date of the policy.

GRANTOR'S RIGHT TO POSSESSION. Until default, 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. 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 reasonable
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.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay 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 shall 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 (i) the term of any applicable insurance policy or (ii) 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. This 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 the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

     DEFAULT ON INDEBTEDNESS. Failure of Grantor to make any payment when due on
     the Indebtedness.

     OTHER DEFAULTS. Failure of Grantor to comply with or to perform any other
     term, obligation, covenant or condition contained in this Agreement or in
     any of the Related Documents or in any other agreement between Lender and
     Grantor.

     DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect Borrower's or any Grantor's ability to repay the
     Loans or perform their respective obligations under this Agreement or any
     of the Related Documents.

     FALSE STATEMENTS. Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Grantor under this Agreement, the
     Note or the Related Documents is false or misleading in any material
     respect, either now or at the time made or furnished.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related Documents
     ceases to be in full force and effect (including failure of any collateral
     documents to create a valid and perfected security interest or 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 receiver
     for any part of Grantor's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Grantor.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Grantor or by any
     governmental agency against the Collateral or any other collateral securing
     the Indebtedness. This includes a garnishment of any of Grantor's 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.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with respect
     to any Guarantor of any of the Indebtedness or such Guarantor dies or
     becomes incompetent. Lender, at its option, may, but shall not be required
     to, permit the Guarantor's estate to assume unconditionally the obligations
     arising under the guaranty in a manner satisfactory to Lender, and, in
     doing so, cure the Event of Default.

     ADVERSE CHANGE. A material adverse change occurs in Grantor's financial
     condition, or Lender believes the prospect of payment or performance of the
     Indebtedness is impaired.

     RIGHT TO CURE. If any default, other than a Default on Indebtedness, is
     curable and if Grantor has not been given a prior notice of a breach of the
     same provision of this Agreement, it may be cured (and no Event of Default
     will have occurred) if Grantor, after Lender sends written notice demanding
     cure of such default, (a)


<PAGE>   4


                          COMMERCIAL SECURITY AGREEMENT
08-01-1997                         (CONTINUED)                          PAGE 4

================================================================================


     cures the default within fifteen (15) days; or (b), if the cure requires
     more than fifteen (15) days, immediately initiates steps which Lender deems
     in Lender's sole discretion to be sufficient to cure the default and
     thereafter continues and completes all reasonable and necessary steps
     sufficient to produce compliance as soon as reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Washington Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness,
     including any prepayment penalty which Grantor would be required to pay,
     immediately due and payable, without notice.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all or
     any portion of the Collateral and any and all certificates of title and
     other documents relating to the Collateral. Lender may require Grantor to
     assemble the Collateral and make it available to Lender at a place to be
     designated by Lender. Lender also shall have full power to enter upon the
     property of Grantor to take possession of and remove the Collateral. If the
     Collateral contains other goods not covered by this Agreement at the time
     of repossession, Grantor agrees Lender may take such other goods, provided
     that Lender 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 its 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 reasonable notice of the time after which any private sale or any
     other intended disposition of the Collateral is to be made. The
     requirements of reasonable notice shall be met if such notice is given at
     least ten (10) days before the time of the sale or disposition. All
     expenses relating to the disposition of the Collateral, including without
     limitation the expenses of retaking, holding, insuring, preparing for sale
     and selling the Collateral, shall become a part of the Indebtedness secured
     by this Agreement and shall be payable on demand, with interest at the Note
     rate from date of expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender shall
     have the following rights and remedies regarding the appointment of a
     receiver: (a) Lender may have a receiver appointed as a matter of right,
     (b) the receiver may be an employee of Lender and may serve without bond,
     and (c) all fees of the receiver and his or her attorney shall become part
     of the Indebtedness secured by this Agreement and shall be payable on
     demand, with interest at the Note rate from date of expenditure until
     repaid.

     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 its discretion transfer any
     Collateral into its own name or that of its 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, choses 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.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether evidenced
     by this Agreement or 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 to
     exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW. This Agreement has been delivered to Lender and accepted by
     Lender in the State of Washington. If there is a lawsuit, Grantor agrees
     upon Lender's request to submit to the jurisdiction of the courts of King
     or Pierce County, the State of Washington. Lender and Grantor hereby waive
     the right to any jury trial in any action, proceeding, or counterclaim
     brought by either Lender or Grantor against the other. This Agreement shall
     be governed by and construed in accordance with the laws of the State of
     Washington.

     ATTORNEYS' FEES; EXPENSES. Grantor agrees to pay upon demand all of
     Lender's costs and expenses, including attorneys' fees and Lender's legal
     expenses, incurred in connection with the enforcement of this Agreement.
     Lender may pay someone else to help enforce this Agreement, and Grantor
     shall pay the costs and expenses of such enforcement. Costs and expenses
     include Lender's attorneys' fees and legal expenses whether or not there is
     a lawsuit, including reasonable attorneys' fees and legal expenses for
     bankruptcy proceedings (and including efforts to modify or vacate any
     automatic stay or injunction), appeals, and any anticipated post-judgment
     collection services. Grantor also shall pay all court costs and such
     additional fees as may be directed by the court.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions

     and every Grantor. This means that each of the persons signing below is
     responsible for ALL obligations in this Agreement.

     NOTICES. All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise required
     by law), and shall be effective when actually delivered or when deposited
     with a nationally recognized overnight courier or deposited in the United
     States mail, first class, postage prepaid, addressed to the party to whom
     the notice is to be given at the address shown above. Any party may change
     its address for notices under this Agreement by giving formal written
     notice to the other parties, specifying that the purpose of the notice is
     to change the party's address. To the extent permitted by applicable law,
     if there is more than one Grantor, notice to any Grantor will constitute
     notice to all Grantors. For notice purposes, Grantor will keep Lender
     informed at all times of Grantor's current address(es).

     POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and lawful
     attorney-in-fact, irrevocably, with full power of substitution to do the
     following after an Event of Default: (a) to demand, collect, receive,
     receipt for, sue and recover all sums of money or other property which may
     now or hereafter become due, owing or payable from the Collateral; (b) to
     execute, sign and endorse any and all claims, instruments, receipts,
     checks, drafts or warrants issued in payment for the Collateral; (c) to
     settle or compromise any and all claims arising under the Collateral, and,
     in the place and stead of Grantor, to execute and deliver its release and
     settlement for the claim; and (d) to file any claim or claims or to take
     any action or institute or take part in any proceedings, either in its own
     name or in the name of the Grantor, or otherwise, which in the discretion
     of Lender may seem to be necessary or advisable. This power is given as
     security for the Indebtedness, and the authority hereby conferred is and
     shall be irrevocable and shall remain in full force and effect until
     renounced by Lender.

     PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted
     preference claim in Borrower's bankruptcy will become a part of the
     Indebtedness and, at Lender's option, shall be payable by Borrower as
     provided above in the "EXPENDITURES BY LENDER" paragraph.

     SEVERABILITY. If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUCCESSOR INTERESTS. Subject to the limitations set forth above on transfer
     of the Collateral, this Agreement shall be binding upon and inure to the
     benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Agreement shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Agreement. No prior waiver by Lender, nor any
     course of dealing between Lender and Grantor, shall constitute a waiver of
     any of Lender's rights or of any of Grantor's obligations as to any future
     transactions. Whenever the consent of Lender is required under this
     Agreement, the granting of such consent by Lender in any instance shall not
     constitute continuing consent to subsequent instances where such consent is
     required and in all cases such consent may be granted or withheld in the
     sole discretion of Lender.

     WAIVER OF CO-OBLIGOR'S RIGHTS. If more than one person is obligated for the
     Indebtedness, Borrower irrevocably waives, disclaims and relinquishes all
     claims against such other person which Borrower has or would otherwise have
     by virtue of payment of the Indebtedness or any part thereof, specifically
     including but not limited to all rights of indemnity, contribution or
     exoneration.

ADDITIONAL OBLIGATIONS OF GRANTOR. This is a continuing Security Agreement and
will continue in affect even though all or any part of the Indebtedness is paid
in full and even though for a period of time Grantor may not be indebted to
Lender; provided that when all the obligations of Grantor to Lender, including
but not limited to the Indebtedness, have been paid in full and Grantor has no
further rights to borrow funds under the Note, the security interest provided
herein shall terminate. At such time, no party hereto shall have any further
rights or obligations hereunder.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED AUGUST 1,
1997.
