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

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 any of Borrower's property or 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 Borrower or any Grantor under this
Agreement or the Related Documents is false or misleading in any material
respect 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 Security
Agreement to create a valid and perfected Security Interest) at any time
and for any reason.

INSOLVENCY. The dissolution or termination of Borrower's existence as a
going business, the insolvency of Borrower, the appointment of a receiver
for any part of Borrower'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 Borrower.

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 Borrower, any creditor
of any Grantor against any collateral securing the Indebtedness, or by any
governmental agency. This includes a garnishment, attachment, or levy on or
of any of Borrower's deposit accounts with Lender. However, this Event of
Default shall not apply if there is a good faith dispute by Borrower or
Grantor, as the case may be, as to the validity or reasonableness of the
claim which is the basis of the creditor or forfeiture proceeding, and if
Borrower or Grantor gives Lender written notice of the creditor or
forfeiture proceeding and furnishes reserves or a surety bond for the
creditor or forfeiture proceeding satisfactory to Lender.

EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with respect
to any Guarantor of any of the Indebtedness or any Guarantor dies or
becomes incompetent, or revokes or disputes the validity of, or liability
under, any Guaranty of the Indebtedness. 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.

CHANGE IN OWNERSHIP. Any change in ownership of twenty-five percent (25%)
or more of the common stock of Borrower.

ADVERSE CHANGE. A material adverse change occurs in Borrower'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 Borrower or Grantor, as the case may be, has not been given
a notice of a similar default within the preceding twelve (12) months, it
may be cured (and no Event of Default will have occurred) if Borrower or
Grantor, as the case may be, after receiving written notice from Lender
demanding cure of such default: (a) 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.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where
otherwise provided in this Agreement or the Related Documents, all commitments
and obligations of Lender under this Agreement or the Related Documents or any
other agreement immediately will terminate and, at Lender's option, all
Indebtedness immediately will become due and payable, all without notice of any
kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional. In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise. Except as may be prohibited by applicable law, all of Lender's rights
and remedies 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 Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.

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

AMENDMENTS. This Agreement, together with any Related Documents,
constitutes the entire and final 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 OREGON. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF MULTNOMAH
COUNTY, THE STATE OF OREGON. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO
ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER
LENDER OR BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF OREGON.

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

CONSENT TO LOAN PARTICIPATION. Borrower agrees and consents to Lender's
sale or transfer, whether now or later, of one or more participation
interests in the Loans to one or more purchasers, whether related or
unrelated to Lender. Lender may provide, without any limitation whatsoever,
to any one or more purchasers, or potential purchasers, any information or
knowledge Lender may have about Borrower or about any other matter relating
to the Loan, and Borrower hereby waives any rights to privacy it may have
with respect to such matters. Borrower additionally waives any

LOAN NO 5009002 (CONTINUED)
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

and all notices of sale of participation interests, as well as all
notices of any repurchase of such participation interests. Borrower also
agrees that the purchasers of any such participation interests will be
considered as the absolute owners of such interests in the Loans and will
have all the rights granted under the participation agreement or agreements
governing the sale of such participation interests. Borrower further waives
all rights of offset or counterclaim that it may have now or later against
Lender or against any purchaser of such a participation interest and
unconditionally agrees that either Lender or such purchaser may enforce
Borrower's obligation under the Loans irrespective of the failure or
insolvency of any holder of any interest in the Loans. Borrower further
agrees that the purchaser of any such participation interests may enforce
its interests irrespective of any personal claims or defenses that Borrower
may have against Lender.

COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
expenses, including without limitation attorneys' fees, incurred in
connection with the preparation, execution, enforcement, modification and
collection of this Agreement or in connection with the Loans made pursuant
to this Agreement. Lender may pay someone else to help collect the Loans
and to enforce this Agreement, and Borrower will pay that amount. This
includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses, whether or not there is a lawsuit,
including attorneys' fees for bankruptcy proceedings (including efforts to
modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. Borrower also will pay any
court costs, in addition to all other sums provided by law.

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 Borrower, notice to any Borrower will constitute
notice to all Borrowers. For notice purposes, Borrower will keep Lender
informed at all times of Borrower's current address(es).

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.

SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of any
provisions of this Agreement makes it appropriate, including without
limitation any representation, warranty or covenant, the word "Borrower" as
used herein shall include all subsidiaries and affiliates of Borrower.
Notwithstanding the foregoing however, under no circumstances shall this
Agreement be construed to require Lender to make any Loan or other
financial accommodation to any subsidiary or affiliate of Borrower.

SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
behalf of Borrower shall bind its successors and assigns and shall inure to
the benefit of Lender, its successors and assigns. Borrower shall not,
however, have the right to assign its rights under this Agreement or any
interest therein, without the prior written consent of Lender.

SURVIVAL. All warranties, representations, and covenants made by Borrower
in this Agreement or in any certificate or other instrument delivered by
Borrower to Lender under this Agreement shall be considered to have been
relied upon by Lender and will survive the making of the Loan and delivery
to Lender of the Related Documents, regardless of any investigation made by
Lender or on Lender's behalf.

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 Borrower, or between Lender and any
Grantor, shall constitute a waiver of any of Lender's rights or of any
obligations of Borrower or of any Grantor 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 in subsequent instances where such consent is required,
and in all cases such consent may be granted or withheld in the sole
discretion of Lender.

PROMISSORY NOTE

PRINCIPAL LOAN DATE MATURITY LOAN NO CALL COLLATERAL ACCOUNT OFFICER INITIALS

PRINCIPAL AMOUNT: $285,000.00 INTEREST RATE: 8.420% DATE OF NOTE: APRIL 1, 1998

PROMISE TO PAY. R-B RUBBER PRODUCTS, INC. ("BORROWER") PROMISES TO PAY TO
KEYBANK NATIONAL ASSOCIATION ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED
STATES OF AMERICA, THE PRINCIPAL AMOUNT OF TWO HUNDRED EIGHTY FIVE THOUSAND &
00/100 DOLLARS ($285,000.00), TOGETHER WITH INTEREST AT THE RATE OF 8.420% PER
ANNUM ON THE UNPAID PRINCIPAL BALANCE FROM APRIL 1, 1998, UNTIL PAID IN FULL.

PAYMENT. BORROWER WILL PAY THIS LOAN IN 60 PAYMENTS OF $5,859.13 EACH PAYMENT.
BORROWER'S FIRST PAYMENT IS DUE MAY 5, 1998, AND ALL SUBSEQUENT PAYMENTS ARE DUE
ON THE SAME DAY OF EACH MONTH AFTER THAT. BORROWER'S FINAL PAYMENT WILL BE DUE
ON APRIL 5, 2003, AND WILL BE FOR ALL PRINCIPAL AND ALL ACCRUED INTEREST NOT YET
PAID. PAYMENTS INCLUDE PRINCIPAL AND INTEREST. Interest on this Note is computed
on a 365/360 simple interest basis; that is, by applying the ratio of the annual
interest rate over a year of 360 days, times the outstanding principal balance,
times the actual number of days the principal balance is outstanding. Borrower
will pay Lender at Lender's address shown above or at such other place as Lender
may designate in writing. Unless otherwise agreed or required by applicable law,
payments will be applied first to accrued unpaid interest, then to principal,
and any remaining amount to any unpaid collection costs and late charges.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law. Except for the foregoing, Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Early
payments will not, unless agreed to by Lender in writing, relieve Borrower of
Borrower's obligation to continue to make payments under the payment schedule.
Rather, they will reduce the principal balance due and may result in Borrower
making fewer payments.

LATE CHARGE. If a payment is 16 DAYS OR MORE LATE, Borrower will be charged
5.000% OF THE REGULARLY SCHEDULED PAYMENT.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults 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 any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any guarantor dies or any of the other events described in this default
section occurs with respect to any guarantor of this Note. (h) A material
adverse change occurs in Borrower's financial condition, or Lender believes the
prospect of payment or performance of the Indebtedness is impaired.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender demanding
cure of such default: (a) 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.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, increase the interest rate on this Note 5.000 percentage points.
The interest rate will not exceed the maximum rate permitted by applicable law.
Lender may hire or pay someone else to help collect this Note if Borrower does
not pay. Borrower also will pay Lender that amount. This includes, subject to
any limits under applicable law, Lender's attorneys' fees and Lender's legal
expenses whether or not there is a lawsuit, including attorneys' fees and legal
expenses for bankruptcy proceedings (including efforts to modify or vacate any
automatic stay or injunction), appeals, and any anticipated post-judgment
collection services. If not prohibited by applicable law, Borrower also will pay
any court costs, in addition to all other sums provided by law. THIS NOTE HAS
BEEN DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF OREGON. IF THERE
IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF MULTNOMAH COUNTY, THE STATE OF OREGON. LENDER AND
BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
OREGON.

GENERAL PROVISIONS. Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive
presentment, demand for payment, protest and notice of dishonor. Upon any change
in the terms of this Note, and unless otherwise expressly stated in writing, no
party who signs this Note, whether as maker, guarantor, accommodation maker or
endorser, shall be released from liability. All such parties agree that Lender
may renew or extend (repeatedly and for any length of time) this loan, or
release any party or guarantor or collateral; or impair, fail to realize upon or
perfect Lender's security interest in the collateral; and take any other action
deemed necessary by Lender without the consent of or notice to anyone. All such
parties also agree that Lender may modify this loan without the consent of or
notice to anyone other than the party with whom the modification is made.

--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

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. 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 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.

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 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. 99-499 ("XXXX"), 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 or intended to protect human health or the environment
("Environmental Laws"). 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 wastes 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
Environmental 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, or as a result of a violation of any
Environmental Laws. 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 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.

04-01-1998 COMMERCIAL SECURITY AGREEMENT PAGE 3
LOAN NO 5009002 (CONTINUED)
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

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: (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 (i) 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. 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 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.

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 any of Borrower's property or 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) 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 Oregon 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

04-01-1998 COMMERCIAL SECURITY AGREEMENT PAGE 4
LOAN NO 5009002 (CONTINUED)
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

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 unless Grantor has
signed, after an Event of Default occurs, a statement renouncing or modifying
Grantor's right to notification of sale. 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 an 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, xxx 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 and final 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 Oregon. If there is a lawsuit, Grantor agrees upon
Lender's request to submit to the jurisdiction of the courts of Multnomah
County, the State of Oregon. 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 Oregon.

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 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 of
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: (a) to demand, collect, receive, receipt for, xxx 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 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

04-01-1998 COMMERCIAL SECURITY AGREEMENT PAGE 5
LOAN NO 5009002 (CONTINUED)
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

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.

INSURANCE REQUIREMENTS. R-B RUBBER PRODUCTS, INC. ("Grantor") understands that
insurance coverage is required in connection with the extending of a loan or the
providing of other financial accommodations to Grantor by Lender. These
requirements are set forth in the security documents. The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

COLLATERAL: ALL EQUIPMENT.
TYPE. All risks, including fire, theft and liability.
AMOUNT. Full insurable value.
BASIS. Actual cash value.
ENDORSEMENTS. Lender's loss payable clause with stipulation that
coverage will not be canceled or diminished without a minimum of
ten (10) days' prior written notice to Lender.
DEDUCTIBLES. $500.00.

INSURANCE COMPANY. Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to Lender.

INSURANCE MAILING ADDRESS. All documents and other materials relating to
insurance for this loan should be mailed, delivered or directed to the following
address:

COMMERCIAL LOAN SERVICES

XXXXX, XX 00000-0000

PROVISION OF INSURANCE. Grantor agrees to deliver to Lender, thirty (30) days
from the date of this Agreement, evidence of the required insurance as provided
above, with an effective date of April 1, 1998, or earlier.

--------------------------------------------------------------------------------
WARNING

Unless Grantor provides Lender with evidence of the insurance coverage as
required by Grantor's security documents, Lender may purchase insurance at
Grantor's expense to protect Lender's interest. This insurance may, but need
not, also protect Grantor's interest. If the collateral becomes damaged, the
coverage Lender purchases may not pay any claim Grantor makes or any claim
made against Grantor. Grantor may later cancel this coverage by providing
evidence that Grantor has obtained property coverage elsewhere. Grantor will
be responsible for the cost of any insurance purchased by Lender. The cost of
this insurance may be added to Grantor's Indebtedness. If the cost is added
to Grantor's Indebtedness, the interest rate on the underlying Indebtedness
will apply to this added amount. The effective date of coverage may be the
date Grantor's prior coverage lapsed or the date Grantor failed to provide
proof of coverage. The coverage Lender purchases may be considerably more
expensive than insurance Grantor can obtain on Grantor's own and may not
satisfy any need for property damage coverage or any mandatory liability
insurance requirements imposed by applicable law.
--------------------------------------------------------------------------------

AUTHORIZATION. For purposes of insurance coverage on the Collateral, Grantor
authorizes Lender to provide to any person (including any insurance
agent or company) all information Lender deems appropriate, whether regarding
the Collateral, the loan or other financial accommodations, or both.
