Principal Amount: $992,000.00 Initial Rate: 7.970%  Date of Note: August 3, 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 NINE HUNDRED NINETY TWO THOUSAND &
00/100 DOLLARS ($992,000.00), TOGETHER WITH INTEREST ON THE UNPAID PRINCIPAL
BALANCE FROM AUGUST 3, 1998, UNTIL PAID IN FULL.

PAYMENT.  SUBJECT TO ANY PAYMENT CHANGES RESULTING FROM CHANGES IN THE INDEX,
BORROWER WILL PAY THIS LOAN IN 119 REGULAR PAYMENTS OF $8,373.20 EACH AND ONE
IRREGULAR LAST PAYMENT ESTIMATED AT $695,954.43.  BORROWER'S FIRST PAYMENT IS
DUE SEPTEMBER 15, 1998, AND ALL SUBSEQUENT PAYMENTS ARE DUE ON THE SAME DAY OF
EACH MONTH AFTER THAT.  BORROWER'S FINAL PAYMENT DUE AUGUST 15, 2008, WILL BE
FOR ALL PRINCIPAL AND ALL ACCRUED INTEREST NOT YET PAID.  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.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change
from time to time based on changes in an independent index which is the weekly
average on United States Treasury Securities adjusted to a constant maturity of
five (5) years as made available by the Federal Reserve Board (the "Index"). 
The Index is not necessarily the lowest rate charged by Lender on its loans.  If
the Index becomes unavailable during the term of this loan, Lender may designate
a substitute index after notice to Borrower.  Lender will tell Borrower the
current Index rate upon Borrower's request.  Borrower understands that Lender
may make loans based on other rates as well.  The interest rate change will not
occur more often than each five years after the first change.  The interest rate
shall be fixed as of the Note date for the subsequent five (5) year period, and
shall

<PAGE>

adjusted as of the first day of the calendar month following the fifth
anniversary date of the Note and on the first day of every sixty-first (61st)
month thereafter ("Change Date") based on the Index published in the Wall Street
Journal or otherwise available to Lender forty-five (45) days prior to the
Change Date.  THE INDEX CURRENTLY IS 5.470% PER ANNUM.  THE INTEREST RATE TO BE
APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL BE AT A RATE OF 2.500
PERCENTAGE POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 7.970% PER
ANNUM.  Whenever increases occur in the interest rate, Lender, at its option,
may do one or more of the following:  (a) increase Borrower's payments to ensure
Borrower's loan will pay off by its original final maturity date, (b) increase
Borrower's payments to cover accruing interest, (c) increase the number of
Borrower's payments, and (d) continue Borrower's payments at the same amount and
increase Borrower's final payment.

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 to
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 obligation 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 either
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 in impaired.

<PAGE>

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 variable interest rate on this Note to 7.500
percentage points over the index.  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.
