    THIS INTERIM FUNDING LOAN AND SECURITY AGREEMENT dated as of May 12, 1997
is made by and between KEYCORP LEASING LTD., a Delaware corporation ("Lessor"),
and R-B RUBBER PRODUCTS, INC., an Oregon corporation having its principal place
of business at 904 East 10th Avenue, McMinnville, OR 97128 ("Lessee").

                              I N T R O D U C T I O N :

    Lessee has entered into (i) Funding Agreement dated as of May 12, 1997 with
Lessor (the "Funding Agreement"), (ii) a Master Equipment Lease Agreement dated
as of May 12, 1997 with Lessor, as lessor (the "Master Lease"), a copy of which
is attached to the Funding Agreement (such Master Lease, together with all
Equipment Schedules executed in connection therewith, in substantially the form
attached to the Funding Agreement, and all addenda attached thereto, if any,
from time to time executed in connection therewith, are hereinafter collectively
referred to as, the "Lease"), (iii) purchase agreements with various vendors
(the "Other Suppliers"), pursuant to which Lessee has agreed to purchase certain
goods and other property from such Other Suppliers, together with goods and
other property purchased from the Main Supplier (as hereinafter defined) (the
"Equipment), and (iv) a purchase agreement (the "Purchase Agreement"), a copy of
which is attached hereto as EXHIBIT B, dated January 4, 1997 with Emil Paul
Schilling AG (the "Main Supplier") and the Other Suppliers, pursuant to which
Lessee has agreed to purchase Equipment.  Lessee has requested Lessor to make
certain payments (the "Advance Payment(s)"), as required by the terms of the
Purchase Agreement and purchase orders with the Other Suppliers, in each case
subsequent to the effectiveness and enforceability of the Master Lease with
respect to such Equipment, but prior to the Rent Commencement Date with respect
to such Equipment, and Lessor is willing to make such Advance Payments, subject
to and upon the terms and conditions set forth herein.  Unless the context
otherwise requires, all capitalized terms used herein without definition shall
have the respective meanings set forth in the Lease.

    NOW, THEREFORE, in consideration of the foregoing premises, the Secured
Obligations between the parties hereunder, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Lessor and Lessee hereby agree as follows:

    1.   THE ADVANCE PAYMENTS.  Subject to the terms and conditions set forth
in (a) this Agreement, (b) the Purchase Agreement, (c) the Lease, (d) the
Promissory Note (as defined herein), and (e) any other agreement executed in
connection therewith (this Agreement, the Purchase Agreement, the Lease, the
Promissory Note and all other such agreements collectively referred to hereafter
as the "Loan Documents"), Lessor hereby agrees to make the Advance Payments upon
Lessee's request at the times and in the amounts set forth in the Purchase
Agreement or the purchase orders with the Other Suppliers. Advance Payments
shall be made to the address set forth in each Drawdown Request (as defined in
the Promissory Note).

    2.   MASTER LEASE IN FULL FORCE AND EFFECT AS TO ADVANCE PAYMENTS.  Lessee
hereby acknowledges that, with respect to the Advance Payments hereunder (and
the Equipment to which such Advance Payments relate), the Master Lease shall be
deemed to be in full force and effect against Lessee with respect to such
Equipment with the same force and effect as if an Equipment Schedule was
executed with respect to each item of such Equipment, and Lessee acknowledged
its unqualified acceptance of each item of such Equipment, on the date of the
Advance Payment hereunder relating thereto.  

    3.   THE PROMISSORY NOTE; INTEREST; REPAYMENT.  The obligations of Lessee
to repay the Advance Payments shall be evidenced by a promissory note (the
"Promissory Note"), in the form attached hereto as EXHIBIT A.  Interest shall be
calculated as set forth in, and repayment made in accordance with, the terms and
conditions of the Promissory Note.


    4.   SECURITY INTEREST.  (a) As security for the payment and performance of
all obligations due to Lessor hereunder and under the Promissory Note,
including, without limitation, repayment of the Advance Payments and all
interest accrued thereon, and any and all other obligations of Lessee under the
Loan Documents (collectively, the "Secured Obligations"), Lessee hereby grants
to Lessor a security interest in and to all of Lessee's right, title and
interest, now existing or hereafter arising, in and to the following: Lessee's
assignment of the 

<PAGE>

Purchase Agreement shall be evidenced by an Assignment of Purchase Agreement in
the form attached hereto as EXHIBIT C (the "Assignment of Purchase Agreement").

         (b) Lessee represents and warrants to Lessor that the Collateral is
free and clear of all claims, liens, encumbrances and charges whatsoever, except
for the security interest granted hereby.  Lessee shall, at Lessee's own cost
and expense, promptly take any action as may be necessary or desirable in order
to discharge any liens (other than the security interest granted hereby) upon
the Collateral arising as a result of any act or omission of Lessee.

    5.   EXPRESS CONDITION TO ADVANCE PAYMENTS.  Lessor shall have no
obligation to make any Advance Payment hereunder (a) if an Event of Default (as
defined in Section 6 hereof) shall have occurred and is continuing), (b) until
such time as Lessor, or its designee, shall have made a physical inspection of
the Equipment which is satisfactory to Lessor in its sole discretion, and (c)
unless Lessor shall have received the following documents duly executed and
delivered by an authorized representative of Lessee and/or the Main Supplier, as

         (1)  the Master Lease; 
         (2)  this Interim Funding Loan and Security Agreement; 
         (3)  UCC Financing Statements, as requested by Lessor; 
         (4)  a Drawdown Request (as defined in the Promissory Note) with
respect to such Advance Payment; 
         (5)  any other instruments or documents as may be reasonably requested
by Lessor; 
         (6)  an invoice issued by the Main Supplier and the Other Suppliers
and countersigned by Lessee (which countersignature by Lessee shall be
conclusively deemed to be Lessee's certification and agreement that the Advance
Payment invoiced is then due and owing and properly payable, and that all
conditions precedent to the payment of such invoice have been performed and
completed to the satisfaction of Lessee, and in accordance with the terms and
conditions of the Purchase Agreement (provided, however, that Lessor shall have
no obligation to make the final Advance Payment due under the Purchase Agreement
until such time as Lessor has received the duly executed Certificate of
Acceptance for the Equipment from the Lessee, as required by the terms of the
Master Lease; 
         (7)  the Purchase Agreement;
         (8)  the Assignment of Contract; and
         (9)  the Consent to Assignment and Agreement, in the form attached
hereto as EXHIBIT D.  

    6.   EVENTS OF DEFAULT; REMEDIES.  (a) The occurrence of any of the
following events shall constitute and be an event of default (an "Event of
Default"): (1) Lessee fails to pay any installment of principal or interest, or
any other payment due and owing, under the Promissory Note or this Agreement
within ten (10) days after the same shall have become due; (2) Lessee becomes
insolvent or makes an assignment for the benefit of its creditors; (3) a

substantial part of Lessee's assets is appointed with or without the application

bankruptcy, insolvency or similar legislation, and, if against, the proceeding
shall continue undismissed, or the order, judgment or decree ordering the
proceeding shall continue unstayed, for thirty (30) or more days; (5) Lessee
violates or fails to perform any provision of either this Agreement, the
Promissory Note, the Lease or any other loan, lease or credit agreement or any
acquisition or purchase agreement with Lessor or any other party (a default
under which third party agreement would materially and adversely effect Lessee),
and such failure shall continue unremedied for 30 days after notice from Lessor
to Lessee, specifying the failure and demanding the same to be remedied; (6)
Lessee violates or fails to perform any covenant or representation made by
Lessee in this Agreement or the Promissory Note, and such violation or failure
shall continue unremedied for 30 days after notice from Lessor to Lessee,
specifying the violation or failure and demanding the same to be remedied; (7)
any representation or warranty made in this Agreement, the Promissory Note, the
Lease, certificate, financial statement or other statement furnished to Lessor

under the Promissory Note; (9) an additional lien attaches to the Equipment; or
10) Lessee makes a bulk transfer of furniture, furnishings, fixtures or other
equipment or inventory; or (11) there is a material adverse change in Lessee's
or any Guarantor's financial condition since the dated of this Agreement.

         (b)  Upon the occurrence of an Event of Default: (1) Lessor shall have
no obligation to make any additional Advance Payments hereunder, (2) Lessor
shall have the right to cause the entire outstanding balance of

of its rights and remedies hereunder and under the Promissory Note, including,
without limitation, reasonable attorneys' fees, and (4) Lessor shall have the
right to exercise any and all remedies available to it hereunder and under the
Promissory Note.

         (c)  The remedies of Lessor provided herein and in the Promissory Note
shall be cumulative and concurrent and may be pursued singly, successively or
concurrently at the sole discretion of Lessor and may be exercised as often as
occasion therefor shall occur.  The failure to exercise, or any delay in the
exercise of, any right or remedy shall in no event be construed as a waiver,
release or exhaustion of any such remedies.

    7.   WAIVER.  LESSEE AND ANY GUARANTOR HEREBY JOINTLY AND SEVERALLY WAIVE
PRESENTMENT FOR PAYMENT, DEMAND, NOTICE OF DEMAND, NOTICE OF NON-PAYMENT, NOTICE
OF PROTEST, PROTEST, AND HEREBY CONSENT TO ANY AND ALL EXTENSIONS OF TIME,

WITH RESPECT TO THE OBLIGATION TO MAKE ANY PAYMENT OF PRINCIPAL OR INTEREST
HEREUNDER, IT BEING UNDERSTOOD AND AGREED THAT THE OBLIGATION TO MAKE SUCH

copy of the Purchase Agreement annexed hereto as EXHIBIT B is true, accurate and
complete in all respects as of the date hereof.

                                   PROMISSORY NOTE


U.S. $1,000,000.00                                           Date:  May 12, 1997

FOR VALUE RECEIVED, R-B RUBBER PRODUCTS, INC., an Oregon corporation with its
principal place of business at 904 East 10th Avenue, McMinnville, OR 97128
("Maker"), promises to pay to the order of KEYCORP LEASING LTD., a Delaware
corporation ("Holder"), the sum of ONE MILLION DOLLARS ($1,000,000.00) in lawful
money of the United States of America or so much thereof as from time to time
shall have been advanced hereunder (the "Principal"), with interest thereon as
hereafter provided ("Interest"), to be paid in the manner set forth herein.

    1.   INTEREST RATE; PLACE OF PAYMENT.  Interest on the balance of the
Principal outstanding on this Promissory Note shall accrue with respect to each
advance hereunder (each, an "Advance") from the date of such Advance and shall
be due and payable at a floating rate per annum (the "Interest Rate") equal to
the Prime Rate (as hereinafter defined) in effect from time to time plus one
percent (1%).  The Interest Rate shall be immediately and correspondingly
adjusted with each change in the Prime Rate.  Interest shall be calculated on
the basis of a 360-day year consisting of twelve 30-day months.  Interest shall
accrue until the date of receipt of payment.  As used herein, the term "Prime
Rate" shall mean the prime rate announced from time to time in THE WALL STREET
JOURNAL.  If the Prime Rate is no longer available, Holder will choose a new
index which is based upon comparable information and will give Maker notice of
such new "Prime Rate."  Payment of the Principal and Interest hereunder shall be
made to Holder at P.O. Box 1865, Albany, New York 12201-1865, or at such other
place as Holder may designate from time to time in writing.

    2.   REPAYMENT TERMS.  Interest on the Principal at the rates aforesaid
shall be due and payable monthly in arrears on the last day of each month
beginning on the month in which Holder funds the first Advance hereunder in
SEPTEMBER, 1997 to and including the earlier of: (a) SEPTEMBER, 1997; or (b) the
date on which a prepayment is required under Section 4(b) hereof; or (c) the
final Rent Commencement Date for the final Schedule under, and as defined in,
the Master Equipment Lease Agreement dated as of May 12, 1997 between the Maker,
as lessee, and the Holder, as lessor (such Master Equipment Lease Agreement,
together with Equipment Schedules from time to time executed in connection
therewith, are hereinafter collectively referred to as, the "Lease"). 
NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, THE ENTIRE UNPAID
BALANCE OF THE PRINCIPAL ADVANCED HEREUNDER, TOGETHER WITH ACCRUED AND UNPAID
INTEREST THEREON AT THE APPLICABLE RATE AFORESAID, SHALL BE DUE AND PAYABLE ON
THE EARLIER OF: (A) SEPTEMBER, 1997; OR (B) THE DATE ON WHICH A PREPAYMENT IS
REQUIRED UNDER SECTION 4(B) HEREOF; OR (C) THE FINAL RENT COMMENCEMENT DATE FOR
THE FINAL SCHEDULE UNDER, AND AS DEFINED IN, THE LEASE.  In addition, Maker will
pay a late payment charge of five percent (5%) of any payment due hereunder that
is more than ten days late, for each month or part thereof that the same remains
unpaid, computed from the due date thereof through the date of receipt thereof. 
Holder reserves the right to require any payment on this Promissory Note,
whether such payment represents a regular installment or a prepayment, to be
payable by wired federal funds or other immediately available funds.

    3.   LOAN AGREEMENT.  This Promissory Note hereby incorporates by reference
all of the terms and conditions of an Interim Funding Loan And Security
Agreement (the "Loan Agreement") dated as of May 12, 1997 between Maker and
Holder to the same extent, and with the same force and effect, as if such terms
and conditions were fully set forth herein and Maker hereby covenants and agrees
to observe and perform such terms and conditions strictly in accordance with the
Loan Agreement.  Requisitions and advances under this Promissory Note shall be
made only on the terms and conditions set forth in the Loan Agreement.  Advances
hereunder shall be requested by a drawdown request in the form attached hereto
as EXHIBIT A (the "Drawdown Request") and shall be evidenced by a drawdown
certificate in the form attached hereto as EXHIBIT B (the "Drawdown
Certificate").

<PAGE>

    4.   PREPAYMENT TERMS.  (a) VOLUNTARY PREPAYMENT.  Maker may prepay, in
connection with any Rent Commencement Date under an Equipment Schedule, the
Principal outstanding hereunder at any time without premium or penalty.

         (b) REQUIRED PREPAYMENT.  In the event that (1) more than $100,000 of
the Equipment to which Advance Payments relate is deemed first placed in service
during a calendar quarter, or (2) any Equipment to which Advance Payments relate
is deemed first placed in service during a calendar year, then, on the final day
of each such calendar quarter or calendar year, as the case may be, Maker shall
prepay an amount of Principal, together with accrued and unpaid interest thereon
at the applicable rate aforesaid, which equals the cost of such Equipment. 
Holder shall apply, and Maker directs Holder to apply, the proceeds of the Lease
to such prepayment, in accordance with and subject to the terms and conditions
of the Funding Agreement dated as of May 12, 1997.

    5.   SECURITY.  Payment of the Principal and Interest hereunder, and the
performance and observance by Maker of all agreements, covenants and provisions
contained herein, is secured by the grant by Maker to Holder of a first priority
security interest in the Collateral (as defined in the Loan Agreement).

    6.   TRANSFER OR ASSIGNMENT.  Holder may at any time assign or otherwise
transfer or negotiate this Promissory Note in whole or in part, without any
notice to Maker.

    7.   APPLICATION OF PAYMENTS.  Each payment received on this Promissory
Note shall be applied first to unpaid late payment charges (if any) hereunder,
then to Interest as of the payment due date and the balance, if any, to the
outstanding Principal as of the date received.

    8.   EVENTS OF DEFAULT.  (a)  The occurrence of any of the "Events of
Default" set forth in the Loan Agreement shall constitute and be an event of
default hereunder (an "Event of Default").

         (b)  Notwithstanding anything to the contrary contained herein, upon
the occurrence of an Event of Default: (i) Holder shall have the right to cause
the entire outstanding balance of the Principal, together with all accrued and
unpaid Interest thereon, to become immediately due and payable without notice or
demand, (ii) Maker shall pay on demand all costs and expenses of Holder with
respect to the enforcement of its rights and remedies hereunder and under the
Loan Agreement, including, without limitation, reasonable attorneys' fees, and
(iii) Holder shall have the right to exercise any and all remedies available to
it hereunder and under the Loan Agreement.

         (c)  The remedies of Holder provided herein and in the Loan Agreement
shall be cumulative and concurrent and may be pursued singly, successively or
concurrently at the sole discretion of Holder and may be exercised as often as
occasion therefor shall occur.  The failure to exercise, or any delay in the
exercise of, any right or remedy shall in no event be construed as a waiver,
release or exhaustion of any such remedies.

    9.   COLLECTION COSTS.  In addition to the Principal, Interest, and any
late payment charges (if any), Holder shall be entitled to collect all costs and
expenses of collection, including, without limitation, reasonable attorneys'
fees, incurred in connection with the protection or realization of the
Collateral or in connection with Holder's collection efforts, whether or not
suit on this Promissory Note or any foreclosure proceeding is filed.  All such
costs and expenses shall be payable on demand and, until paid, shall be secured
by the security interest evidenced by the Loan Agreement and all other
collateral, if any, held by Holder as security for Maker's obligations under
this Promissory Note.

    10.  BINDING AGREEMENT; GOVERNING LAW.  THIS AGREEMENT IS BEING DELIVERED
IN THE STATE OF NEW YORK AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE.  The provisions of this Promissory Note shall be
binding upon, and shall inure to the benefit of, the parties hereto and their
respective successors and assigns.

    11.  MORE THAN ONE SIGNER.  If more than one person or entity signs this
Promissory Note as a Maker, the obligations contained herein shall be deemed
joint and several and all references to "Maker" shall apply both individually
and jointly.

<PAGE>

    12.  GENERAL.  Maker represents and warrants that this Promissory Note
evidences a loan for business or commercial purposes.  By signing this
Promissory Note, Maker agrees to be legally bound to all terms and conditions
contained herein.

    13.  WAIVER.  MAKER AND ALL ENDORSERS, SURETIES, AND GUARANTORS HEREOF
HEREBY JOINTLY AND SEVERALLY WAIVE PRESENTMENT FOR PAYMENT, DEMAND, NOTICE OF
NON-PAYMENT OR DISHONOR, NOTICE OF PROTEST AND PROTEST OF THIS PROMISSORY NOTE. 
MAKER HEREBY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY LITIGATION IN ANY COURT
WITH RESPECT TO, IN CONNECTION WITH OR ARISING OUT OF, THIS PROMISSORY NOTE OR
ANY DOCUMENT DELIVERED IN CONNECTION WITH THIS PROMISSORY NOTE.

    14.  USURY; PARTIAL INVALIDITY. .  (a)  At no time shall the Interest Rate
(or any other late charges or other amounts paid or collected hereunder) exceed
the highest rate allowed by applicable law for this type of loan. Should Holder
ever collect interest at a rate that exceeds the such applicable legal limit,
such excess will be credited to the Principal.  If the amount of the credit
exceeds the balance of the Principal then outstanding on this Promissory Note,
such excess will be returned to Maker; and the effective rate of interest
automatically shall be reduced to the maximum lawful contract rate allowed under
Applicable Law as now or hereafter construed by the courts having jurisdiction
thereof.  Notwithstanding the foregoing, if any applicable state law is amended
or the law of the United States of America preempts any applicable state law, so
that it becomes lawful for Holder to receive a greater per annum interest rate
than is presently allowed by law, the Maker agrees that, on the effective date
of such amendment or preemption, as the case may be, the lawful maximum
hereunder shall be increased to the maximum interest rate per annum allowed by
the amended state law or the law of the United States of America (but not in
excess of the Interest Rate provided for herein).  All calculations of the rate
of interest contracted for, charged or received under this Note or the Loan
Agreement which are made for the purpose of determining whether such rate
exceeds the maximum lawful contract rate, shall be made, to the extent permitted
by applicable law, by amortizing, prorating, allocating and spreading in equal
parts during the period of the full stated term of the indebtedness evidenced
hereby, all interest at any time contracted for, charged or received from the
Maker or otherwise by Holder in connection with the Secured Obligations (as
defined in the Loan Agreement).

         (b)  Whenever possible, each provision of this Promissory Note shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Promissory Note shall be prohibited by or invalid
under the laws of any jurisdiction, such provision, as to such jurisdiction,
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Promissory Note in any other jurisdiction.

    15.  NOTICES.  All notices and other communications under this Promissory
Note shall be in writing and shall be addressed: (i) if to Maker, R-B RUBBER
PRODUCTS, INC., 904 East 10th Avenue, McMinnville, OR 97128; and (ii) if to
Holder, KEYCORP LEASING LTD., 54 State Street, Albany, New York 12207,
Attention: Business Coordinator, or such other address as either party hereto
shall communicate to the other party at its address specified above.  All such
notices and other communications shall be deemed to have been duly given if
delivered by hand or if sent by certified mail, return receipt requested, to the
party to whom such notice is intended to be given, and shall be effective upon
receipt.
