ITEM 1.   FINANCIAL STATEMENTS





                         REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors
R-B Rubber Products, Inc.

We have made a review of the condensed balance sheets of R-B Rubber Products,
Inc. as of June 30, 1998 and December 31, 1997, the related condensed statements
of operations for the three and six month periods ended June 30, 1998 and 1997,
and the related condensed statements of cash flows for the six month periods
ended June 30, 1998 and 1997, in accordance with standards established by the
American Institute of Certified Public Accountants.

A review of the interim financial information consists principally of obtaining
an understanding of the system for the preparation of interim financial
information, applying analytical review procedures to financial data, and making
inquiries of persons responsible for financial and accounting matters.  It is
substantially less in scope than an audit in accordance with generally accepted
auditing standards, the objective of which is the expression of an opinion
regarding the financial statements taken as a whole.  Accordingly, we do not
express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the condensed financial statements referred to above for them to be
in conformity with generally accepted accounting principles.

NOTE 3.  ACQUISITION
On April 1, 1998, the Company announced the acquisition of substantially all of
the assets of certain operations of Iowa Mat Company for $600,000 in cash and
66,667 shares of the Company's Common Stock with a value on the date of issuance
of $216,668.  In addition, based upon achieving certain revenue goals from Iowa
Mat Company products, the Company is required to issue an additional $200,000 of
the Company's Common Stock to the sellers of Iowa Mat Company based upon the
then current market price of the Company's Common Stock.  A majority of the
$600,000 cash payment was financed with the Company's existing bank facilities.

The acquisition was accounted for as a purchase.  Pro forma results of
operations are not presented as they are not materially different from
historical results of operations.

NOTE 4.  EARNINGS PER SHARE
Beginning December 31, 1997, basic earnings per share (EPS) and diluted EPS are
computed using the methods prescribed by Statement of Financial Accounting
Standard No. 128, EARNINGS PER SHARE (SFAS 128). Basic EPS is calculated using
the weighted average number of common shares outstanding for the period and
diluted EPS is computed using the weighted average number of common shares and
dilutive common equivalent shares outstanding.   Prior period amounts have been
restated to conform with the presentation requirements of SFAS 128.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

FORWARD LOOKING STATEMENTS
This Quarterly Report on Form 10-QSB, including Management's Discussion and
Analysis or Plan of Operation, contains forward-looking statements that involve
a number of risks and uncertainties.  Future market conditions are subject to
supply and demand conditions and decisions of other market participants over
which the Company has no control and which are inherently very difficult to
predict.  Accordingly, there can be no assurance that the Company's revenues or
gross margins will improve.  In addition, there are other factors that could
cause actual results to differ materially, including competitive pressures,
increased demand for, or diminished supply of, the Company's raw materials,
unanticipated difficulties in integrating acquired technologies or businesses
and the risk factors listed from time to time in the Company's Securities and
Exchange Commission reports, including, but not limited to, the report of Form
10-KSB for the year ended December 31, 1997.  The Company wished to caution the
reader that these forward looking statements, such as the statements concerning
new product introductions and future tire chip processing capabilities, are only
predictions and are not statements of historical fact.

RESULTS OF OPERATIONS
Net sales increased 14 percent to $2.0 million for the second quarter of 1998
from $1.7 million for the second quarter of 1997 and increased 16 percent to
$3.9 million for the first half of 1998 compared to $3.4 million for the first
half of 1997. The increases were primarily attributable to the Company's
continued expansion in its primary markets.  Sales for the

                                       7
<PAGE>

second quarter and year to date periods for 1998 also include $120,000 of
sales from the Company's new molded product division related to the Iowa Mat
acquisition.

Gross profit decreased to $364,000 and $1.1 million, respectively (18.5
percent and 28.9 percent of net sales, respectively) for the three month and
six month periods ended June 30, 1998 from $716,000 and $1.4 million,
respectively (41.5 percent and 40.8 percent of net sales, respectively) for
the comparable periods of 1997. The decrease in the gross margin as a percent
of net sales is primarily a result of a negative $133,000 margin related to
the molded product sales, an inventory write-down of $70,000 related to
certain mats that will be re-ground and manufactured into new products and
increased maintenance costs of approximately $35,000.  The Company expects
maintenance costs to remain at current levels due to the increased amount of
plant and equipment the Company is currently operating. In addition, raw
material costs have increased from the prior year due to an inadequate supply
of truck tire chips, which necessitated supplementing raw materials with
buffings.  The Company is currently working to increase its supply of truck
tire chips from its current vendor, but anticipates that its raw material
costs will continue to be higher compared to prior periods until such
increases are sufficient to meet the Company's requirements.  The negative
margin generated by the molded products division included several one-time
costs associated with bringing the production processes and quality of
product up to Company standards.

Selling expenses increased to $201,000 and $431,000, respectively (10.2 percent
and 11.1 percent of net sales, respectively) for the three month and six month
periods ended June 30, 1998 from $172,000 and $317,000, respectively (10.0
percent and 9.5 percent of net sales, respectively) for the comparable periods
of 1997. The increase is primarily a result of increased spending on product
promotion and advertising, including costs for the recently acquired molded
products division.  In addition, the Company has increased sales personnel.

General and administrative expenses increased to $371,000 and $693,000,
respectively (18.9 percent and 17.8 percent of net sales, respectively) for
the three month and six month periods ended June 30, 1998 from $293,000 and
$597,000, respectively (17.0 percent and 17.8 percent of net sales,
respectively) for the comparable periods of 1997, primarily as a result of
one-time costs related to the Iowa Mat acquisition, partially offset by
efficiencies gained as the Company grows.

Net loss was $150,000 and $17,000, respectively for the three month and six
month periods ended June 30, 1998 compared to net income of $147,000 and
$267,000, respectively (8.5 percent and 8.0 percent of net sales, respectively),
for the comparable periods of 1997, as a result of the individual line item
changes discussed above.

LIQUIDITY AND CAPITAL RESOURCES
At June 30, 1998 working capital was $0.8 million, including $164,000 of cash
and cash equivalents.  In the first six months of 1998, working capital
decreased by $520,000 and the current ratio decreased to 1.6:1 from 3.1:1 at
December 31, 1997.

Cash and cash equivalents decreased $128,000 primarily due to $0.6 million used
for the purchase of property and equipment and $0.6 million used for the
purchase of Iowa Mat Company, offset by $267,000 provided by operations,
$214,000 provided by net short-term borrowings and $0.6 million provided by
long-term borrowings.

                                       8
<PAGE>

Accounts receivable decreased $122,000 to $788,000 at June 30, 1998 compared to
$910,000 at December 31, 1997.  Days sales outstanding decreased to 36 days at
June 30, 1998 compared to 37 days at December 31, 1997.

Inventories increased $264,000 to $956,000 at June 30, 1998 from $692,000 at
December 31, 1997 due primarily to building of finished goods inventory in order
to help ensure adequate quantities are available to meet anticipated demand.
Inventory turned approximately seven times on an annualized basis during the
second quarter of 1998 compared to nine times for all of 1997.

Accounts payable increased $206,000 to $610,000 at June 30, 1998 from $404,000
at December 31, 1997 primarily as a result in the build-up of inventory and
amounts related to the Company's building expansion.

Capital expenditures of $571,000 during the first half of 1998 primarily
resulted from the addition of equipment to automate the production and handling
of the Company's mat products as well as continued expansion of the Company's
rubber processing facility.  Total capital expenditures are expected to be not
more than $2.0 million during 1998 and will be incurred primarily to purchase
and/or refurbish existing rubber processing equipment in order to further
increase production capacity and to increase the capability to use additional
tire chips instead of buffings, to purchase production equipment to diversify
the Company's product offerings and to construct an addition to the Company's
production facility.  The $2.0 million of capital expenditures will be financed
primarily through the use of existing tax credits available to the Company.
The Company is currently working on a $1.2 million tax credit lease that is
scheduled to close by the end of 1998.

On April 1, 1998, the Company announced the acquisition of substantially all of
the assets of certain divisions of Iowa Mat Company for $600,000 in cash and
66,667 shares of the Company's Common Stock.  In addition, based upon achieving
certain revenue goals from Iowa Mat Company products, the Company is required to
issue an additional $217,000 of the Company's Common Stock to the sellers of
Iowa Mat Company based upon the then current market price of the Company's
Common Stock. The $600,000 cash payment was financed with the Company's existing
bank facilities.

The Company is currently working on a building expansion to accommodate the
equipment related to the Iowa Mat acquisition and other additional production
equipment.  The Company intends to refinance its existing building mortgage to
also include the costs for the expansion.  The Company expects to achieve a
better interest rate, and expects the refinancing to close before the end of
August 1998.  The Company also intends to decrease its short-term debt with a
portion of the proceeds from the refinancing.

At June 30, 1998, the Company had a $750,000 operating line of credit, which
bore interest at prime plus 0.25 percent, 8.75 percent at June 30, 1998.  The
Company had $273,000 outstanding under this line of credit at June 30, 1998 and
was in compliance with all covenants.  In August 1998, this line of credit was
amended to increase the available amount to $1.0 million, bearing interest at
prime.

NEW ACCOUNTING PRONOUNCEMENTS
In June 1997, the FASB issued Statement of Financial Accounting Standards No.
130 "Reporting Comprehensive Income" ("SFAS 130").  This statement establishes
standards for reporting and displaying comprehensive income and its components
in a full set of general purpose financial statements.  The objective of SFAS
130 is to report a measure of all changes in equity of an enterprise that result
from transactions and other economic events of the period other than
transactions with owners.  The Company adopted SFAS 130 during the first quarter
of 1998.  Comprehensive income (loss) did not differ from currently reported net
income (loss) in the periods presented.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, "Accounting for Derivative Instruments and Hedging Activities ("SFAS
133"). SFAS 133 establishes accounting and reporting standards for all
derivative instruments.  SFAS 133 is effective for fiscal years beginning
after June 15, 1999.  The Company does not have any derivative instruments
and, accordingly, the adoption of SFAS 133 will have no impact on the
Company's financial position or results of operations.

          3.1    REPRESENTATIONS AND WARRANTIES.  Seller makes the following
representations and warranties:

          (a)    Seller is now and on the closing date will be a corporation 
                 duly organized and validly existing under the laws of the 
                 State of Iowa.  Seller has all requisite corporate power and 
                 authority to own and operate the Assets and to carry on the 
                 Business as now being conducted.

          (b)    The execution, delivery, and performance of this Agreement 
                 have been duly authorized and approved by the Board of 
                 Directors and shareholders of Seller, and this Agreement 
                 constitutes a valid and binding agreement of Seller in 
                 accordance with its terms.

          (c)    Seller holds good and marketable title to the Assets, free 
                 and clear of restrictions on or conditions to transfer or 
                 assignment and free and clear of liens, pledges, charges, or 
                 encumbrances.

          (d)    Seller is not aware of any labor dispute or labor trouble 
                 involving employees of Seller and represents that there has 
                 not been any such dispute or trouble during the three years 
                 preceding the effective date of this Agreement.

          (e)    Seller has no knowledge of any claim, litigation, proceeding, 
                 investigation, or governmental action pending or threatened 
                 against Seller which might result in any material change in 
                 the Business or the condition of the Assets.

          (f)    On the closing date, there will be no material leases, 
                 employment contracts, contracts for services or maintenance, 
                 or other similar contracts relating to or connected with the 
                 Assets.

          (g)    Seller acknowledges and understands that the Stock which will 
                 be issued to Seller pursuant to Section 2.2 represents a 
                 minority interest in Buyer and that Seller will not be in a 
                 position to exercise voting control over the business and 
                 affairs of Buyer.

          (h)    The Products, and the processes used in the manufacture 
                 thereof, do not violate or infringe upon any person's patent, 
                 trademark, copyright, or other claim to or right in 
                 intellectual property.

          (i)    Seller knows of no fact which has resulted or which, in the 
                 reasonable judgment of Seller, will result in a material 
                 change in the Assets or in the

                                       4
<PAGE>

                 marketability of the Products other than material changes
                 resulting from this Agreement and the consummation of the
                 transaction contemplated thereby.

          (j)    The execution and delivery of this Agreement by Seller and 
                 the consummation of the transaction contemplated hereunder 
                 will not result in the creation or imposition of any valid 
                 lien, charge, or encumbrance on any of the Assets except as 
                 contemplated by this Agreement and will not require the 
                 authorization, consent, or approval of any third party.

          (k)    Seller has not employed any broker or finder in connection 
                 with the transaction contemplated by this Agreement or taken 
                 any action that would give rise to a valid claim against any 
                 party for a brokerage commission, finder's fee, or other 
                 similar payment.

          (l)    None of the representations or warranties of Seller contain 
                 any untrue statement of a material fact or omit or misstate a 
                 material fact necessary in order to make the statements 
                 contained therein not misleading.

          (m)    All representations and warranties made by Seller shall
                 survive the closing date.

this Agreement and the closing date, Seller will:

          (a)    Operate the Business in the usual and ordinary course and in 
                 substantial conformity with the Interim Agreement between the 
                 parties dated March 5, 1998 ("Interim Agreement") and all 
                 applicable laws, ordinances, regulations, rules, and orders 
                 and use its best efforts to preserve the Business and the 
                 continued operation thereof with Seller's customers, 
                 suppliers, and others having relations with Seller;

          (b)    Not assign, sell, lease, or otherwise transfer or dispose of 
                 any of the Assets, whether now owned or hereafter acquired, 
                 except in the normal and ordinary course of business and in 
                 connection with the normal operation of the Business;

          (c)    Maintain the Assets in their present condition, reasonable 
                 wear and tear and ordinary usage excepted;

          (d)    Not distribute cash or other property to its shareholders;

          (e)    Not pay a bonus to or increase the compensation of any 
                 employee;

                                       5
<PAGE>

     (f)  Provide Buyer and its representatives with reasonable access during 
          business hours to the Assets and the records of the Business and 
          furnish such additional information concerning the Business as Buyer 
          from time to time may reasonably request;

     (g)  Comply with all applicable requirements of the Worker Adjustment
          Retraining Notification Act, 29 USC Section 2101, et seq; and

     (h)  Exercise its best efforts to effect to consummate the transaction
          contemplated by this Agreement and satisfy all of Seller's obligations
          under this Agreement.

     3.3  COVENANT TO COOPERATE.  The parties intend to cooperate with one
another with respect to the collection of Seller's accounts receivable in order
to avoid duplication of effort and preserve valuable customer relationships.
Towards that end, Seller will comply with all reasonable requests made by Buyer
as to all aspects of the collection of such accounts receivable.

     3.4  COVENANT NOT TO COMPETE.  For a period of three years following the
closing date, Seller will not, within the continent of North America, directly
or indirectly (i) own, as a partner, stockholder, or otherwise, an interest in
or (ii) participate in the management, operation, or control of or (iii) perform
services or act in the capacity of an independent contractor, consultant, or
agent of any enterprise directly or indirectly engaged in the manufacture or
sale of any product manufactured or sold by Buyer, including but not limited to
Products and New Products, or other goods or products competitive with any such
product.  Further, for a period of three years following the expiration of the
License (as defined in Section 6.1), Seller will not, within the continent of
North America, directly or indirectly (i) own, as a partner, stockholder, or
otherwise, an interest in or (ii) participate in the management, operation, or
control of or (iii) perform services or act in the capacity of an independent
contractor, consultant, or agent of any enterprise directly or indirectly

competitive with Brick Mats.  Finally, Seller will not, for a period of three
years following the closing date, directly or indirectly suggest, request, or
encourage any prior suppliers or customers of Seller to curtail, reduce, or
cancel their business done with Buyer. Seller agrees that it would be impossible
to measure the damage to Buyer resulting from a breach of any covenant set forth
in this Section 3.4 by Seller and that monetary damages would be an inadequate
remedy for any such breach.  Accordingly, Seller agrees that, if Seller breaches
such a covenant, Buyer shall be entitled, in addition to all other remedies it
may have at law or in equity, to an injunction or other appropriate order
restraining any such breach, without showing or proving any actual damage
sustained by Buyer.  In the event that a covenant set forth in this Section 3.4
is determined by any court of competent jurisdiction to be unenforceable by
reason of its extending for too great a period of time or over too great a
geographical area or by reason of its being too extensive in any other respect,
it shall be interpreted to extend only over the maximum period of time for which
it may be enforceable and/or over the maximum geographical area as to which it
may be enforceable and/or to the maximum extent in all other respects as to
which it may be enforceable, all as determined by such court in such action.

                                       6

     3.5  COVENANT TO EXTEND INTERIM AGREEMENT.  At Buyer's request, Seller will

positions consistent with the IRS Form 8594 or other document described in
Section 1.5.

     existing, and in good standing under the laws of the state of Borrower's
     incorporation and is validly existing and in good standing in all states in

     governmental regulation, court decree, or order applicable to Borrower.

     FINANCIAL INFORMATION. Each financial statement of Borrower supplied to
     Lender truly and completely disclosed Borrower's financial condition as of
     the date of the statement, and there has been no material adverse change in
     Borrower's financial condition subsequent to the date of the most recent
     financial statement supplied to Lender. Borrower has no material contingent
     obligations except as disclosed in such financial statements.

     LEGAL EFFECT. This Agreement constitutes, and any instrument or agreement
     required hereunder to be given by Borrower when delivered will constitute,
     legal, valid and binding obligations of Borrower enforceable against
     Borrower in accordance with their respective terms.

     PROPERTIES. Except as contemplated by this Agreement or as previously
     disclosed in Borrower's financial statements or in writing to Lender and as
     accepted by Lender, and except for property tax liens for taxes not
     presently due and payable, Borrower owns and has good title to all of
     Borrower's properties free and clear of all Security Interests, and has not
     executed any security documents or financing statements relating to such
     properties. All of Borrower's properties are titled in Borrower's legal
     name, and Borrower has not used, or filed a financing statement under, any
     other name for at least the last five (5) years.

     HAZARDOUS SUBSTANCES. The terms "hazardous waste," "hazardous substance,"
     "disposal," "release," and "threatened release," as used in this Agreement,
     shall have the same meanings as set forth in the "CERCLA," "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 or intended to protect human
     health or the environment ("Environmental Laws"). Except as disclosed to
     and acknowledged by Lender in writing, Borrower represents and warrants
     that: (a) During the period of Borrower's ownership of the properties,
     there has been no use, generation, manufacture, storage, treatment,
     disposal, release or threatened release of any hazardous waste or substance
     by any person on, under, about or from any of the properties, (b) Borrower
     has no knowledge of, or reason to believe that there has been (i) any use,
     generation, manufacture, storage, treatment, disposal, release, or
     threatened release of any hazardous waste or substance on, under, about or
     from the properties by any prior owners or occupants of any of the
     properties, or (ii) any actual or threatened litigation or claims of any
     kind by any person relating to such matters. (c) Neither Borrower nor any
     tenant, contractor, agent or other authorized user of any of the properties
     shall use, generate, manufacture, store, treat, dispose of, or release any
     hazardous waste or substance on, under, about or from any of the
     properties; and any such activity shall be conducted in compliance with all
     applicable federal, state, and local laws, regulations, and ordinances,
     including without limitation Environmental Laws. Borrower authorizes Lender
     and its agents to enter upon the properties to make such inspections and
     tests as Lender may deem appropriate to determine compliance of the
     properties with this section of the Agreement. Any inspections or tests
     made by Lender shall be at Borrower's expense and for Lender's purposes
     only and shall not be construed to create any responsibility or liability
     on the part of Lender to Borrower or to any other person. The
     representations and warranties contained herein are based on Borrower's due
     diligence in investigating the properties for hazardous waste and hazardous
     substances. Borrower hereby (a) releases and waives any future claims
     against Lender for indemnity or contribution in the event Borrower 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, losses,
     liabilities, damages, penalties, and expenses which Lender may directly or
     indirectly sustain or suffer resulting from a breach of this section of the
     Agreement or as a consequence of any use, generation, manufacture, storage,
     disposal, release or threatened release occurring prior to Borrower's
     ownership or interest in the properties, whether or not the same was or
     should have been known to Borrower, or as a result of a violation of any
     Environmental Laws. The provisions of this section of the Agreement,
     including the obligation to indemnify, shall survive the payment of the
     Indebtedness and the termination or expiration of this Agreement and shall
     not be affected by Lender's acquisition of any interest in any of the
     properties, whether by foreclosure or otherwise.

     LITIGATION AND CLAIMS. No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     TAXES. To the best of Borrower's knowledge, all tax returns and reports of
     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,
     except those presently being or to be contested by Borrower in good

     on the Loans.

     OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     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

<PAGE>

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.

UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY US (LENDER)
AFTER OCTOBER 3,1989 CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT
FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OR SECURED SOLELY BY THE BORROWER'S
RESIDENCE MUST BE IN WRITING, EXPRESS CONSIDERATION AND BE SIGNED BY US TO BE
ENFORCEABLE.

PRINCIPAL AMOUNT:  $285,000.00      INTEREST RATE:  8.420%     DATE OF NOTE:  APRIL 1, 1998
</TABLE>
 
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.

ENFORCEABLE.

  INDEBTEDNESS IS PAID IN FULL AND EVEN THOUGH FOR A PERIOD OF TIME GRANTOR MAY
  NOT BE INDEBTED TO LENDER.

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

  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 ("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 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.

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

<PAGE>

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, 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 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, 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 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

<PAGE>

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.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED APRIL 1,
1998.

- ----------------------------------------------------------------------------------------------------
</TABLE>
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:

               KEYBANK NATIONAL ASSOCIATION
               COMMERCIAL LOAN SERVICES
               P.O. BOX 5278
               BOISE, ID 83705-5278
               (800) 539-2191

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.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO PROVIDE
INSURANCE AND AGREES TO ITS TERMS. THIS AGREEMENT IS DATED APRIL 1, 1998.

     existing, and in good standing under the laws of the state of Borrower's
     incorporation and is validly existing and in good standing in all states in

     businesses or financial condition.

     AUTHORIZATION. The execution, delivery, and performance of this Agreement
     and all Related Documents by Borrower, to the extent to be executed,

     any provision of its articles of incorporation or organization, or bylaws,
     or any agreement or other instrument binding upon Borrower or (b) any law,
     governmental regulation, court decree, or order applicable to Borrower.

     FINANCIAL INFORMATION. Each financial statement of Borrower supplied to
     Lender truly and completely disclosed Borrower's financial condition as of
     the date of the statement, and there has been no material adverse change in
     Borrower's financial condition subsequent to the date of the most recent
     financial statement supplied to Lender. Borrower has no material contingent
     obligations except as disclosed in such financial statements.

     LEGAL EFFECT. This Agreement constitutes, and any instrument or agreement
     required hereunder to be given by Borrower when delivered will constitute,
     legal, valid and binding obligations of Borrower enforceable against
     Borrower in accordance with their respective terms.

     PROPERTIES. Except as contemplated by this Agreement or as previously
     disclosed in Borrower's financial statements or in writing to Lender and as
     accepted by Lender, and except for property tax liens for taxes not
     presently due and payable, Borrower owns and has good title to all of
     Borrower's properties free and clear of all Security Interests, and has not
     executed any security documents or financing statements relating to such
     properties. All of Borrower's properties are titled in Borrower's legal
     name, and Borrower has not used, or filed a financing statement under, any
     other name for at least the last five (5) years.

     HAZARDOUS SUBSTANCES. The terms "hazardous waste," "hazardous substance,"
     "disposal," "release," and "threatened release," as used in this Agreement,
     shall have the same meanings as set forth in the "CERCLA," "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 or intended to protect human
     health or the environment ("Environmental Laws"). Except as disclosed to
     and acknowledged by Lender in writing, Borrower represents and warrants
     that: (a) During the period of Borrower's ownership of the properties,
     there has been no use, generation, manufacture, storage, treatment,
     disposal, release or threatened release of any hazardous waste or substance
     by any person on, under, about or from any of the properties. (b) Borrower
     has no knowledge of, or reason to believe that there has been (i) any use,
     generation, manufacture, storage, treatment, disposal, release, or
     threatened release of any hazardous waste or substance on, under, about or
     from the properties by any prior owners or occupants of any of the
     properties, or (ii) any actual or threatened litigation or claims of any
     kind by any person relating to such matters. (c) Neither Borrower nor any
     tenant, contractor, agent or other authorized user of any of the properties
     shall use, generate, manufacture, store, treat, dispose of, or release any
     hazardous waste or substance on, under, about or from any of the
     properties; and any such activity shall be conducted in compliance with all
     applicable federal, state, and local laws, regulations, and ordinances,
     including without limitation Environmental Laws. Borrower authorizes Lender
     and its agents to enter upon the properties to make such inspections and
     tests as Lender may deem appropriate to determine compliance of the
     properties with this section of the Agreement. Any inspections or tests
     made by Lender shall be at Borrower's expense and for Lender's purposes
     only and shall not be construed to create any responsibility or liability
     on the part of Lender to Borrower or to any other person. The
     representations and warranties contained herein are based on Borrower's due
     diligence in investigating the properties for hazardous waste and hazardous
     substances. Borrower hereby (a) releases and waives any future claims
     against Lender for indemnity or contribution in the event Borrower 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, losses,
     liabilities, damages, penalties, and expenses which Lender may directly or
     indirectly sustain or suffer resulting from a breach of this section of the
     Agreement or as a consequence of any use, generation, manufacture, storage,
     disposal, release or threatened release occurring prior to Borrower's
     ownership or interest in the properties, whether or not the same was or
     should have been known to Borrower, or as a result of a violation of any
     Environmental Laws. The provisions of this section of the Agreement,
     including the obligation to indemnify, shall survive the payment of the
     Indebtedness and the termination or expiration of this Agreement and shall
     not be affected by Lender's acquisition of any interest in any of the
     properties, whether by foreclosure or otherwise.

     LITIGATION AND CLAIMS. No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     TAXES. To the best of Borrower's knowledge, all tax returns and reports of
     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,
     except those presently being or to be contested by Borrower in good

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

     DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when due
     on the Loans.

     OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     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 9003                     (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.

UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY US (LENDER)
AFTER OCTOBER 3, 1989 CONCERNING LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT
FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OR SECURED SOLELY BY THE BORROWER'S

ENFORCEABLE.

PRINCIPAL AMOUNT:  $315,000.00      INTEREST RATE:  7.920%     DATE OF NOTE:  APRIL 1, 1998
</TABLE>
 
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 THREE HUNDRED FIFTEEN THOUSAND &
00/100 DOLLARS ($315,000.00), TOGETHER WITH INTEREST AT THE RATE OF 7.920% 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 $6,398.63 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.

  request of Lender, Grantor will deliver to Lender any and all of the

LOAN NO 9003                     (CONTINUED)
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

  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 ("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 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
  canceled 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.


<PAGE>

04-01-1998               COMMERCIAL SECURITY AGREEMENT                    PAGE 3
LOAN NO 9003                     (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 (f) 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

LOAN NO 9003                     (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 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 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, 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 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.

</TABLE>
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:

               KEYBANK NATIONAL ASSOCIATION
               COMMERCIAL LOAN SERVICES
               P.O. BOX 5278
               BOISE, ID 83705-5278
               (800) 539-2191

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.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO PROVIDE
INSURANCE AND AGREES TO ITS TERMS. THIS AGREEMENT IS DATED APRIL 1, 1998.

(c)  The Schedule shall commence on June 10, 1998 and shall continue for
     ninety-five (95) months thereafter.

(d)  Lessee shall owe ninety-five (95) basic monthly rental payments in
     arrears each in the amount of $2,224.00 (plus applicable sales/use
     taxes).  The first such payment shall  be due on July 10, 1998 and shall
     continue on the same day of each month thereafter until the end of the
     term of this Schedule.  In addition, Lessee shall pay daily pro rata
     rental in the amount of $74.13 per day (plus applicable sales/use taxes)
     from the date on which Lessee executes a Delivery and Acceptance
     Certificate for the Property through June 9, 1998.  Such daily pro rata
     rental shall be due and payable upon execution by Lessee of a Delivery
     and Acceptance Certificate with regard to the Property.

(e)  The property will be installed or stored at the following address:  904
     East Tenth Avenue, McMinnville, Oregon  97128, COUNTY: Yamhill;

(f)  The record owner of the premises at which the Property will be installed
     or stored is:;

     1.   LATE CHARGE.  If any installment of Rent shall not be received by
Lessor or Lessor's Assignee within ten (10) days after such amount is due,
Lessee shall pay to Lessor a late charge equal to five percent (5.0%) of such
overdue amount.

2.   TITLE PASSAGE.  a.  As long as no event of default has occurred under the
Lease, Lessee shall have the options, to purchase all, but not part, of the
Property at the end of sixty (60) months hereinafter called the "Mid-Term Option
Date",  and "Mid-Term Option" or at the end of the Term or any renewal
thereof (hereinafter called the "End of Term Option Date" and "End
of Term Option").

     b.   The above Options may only be exercised by Lessee by written notice of
such exercise to Lessor, which notice must be received by Lessor not later
than one hundred eighty (180) days prior to: 1) the Mid-Term Option date
to exercise the Mid-Term Option; or 2) the End of Term Option Date to
exercise the End of Term Option.  Payment of the purchase price must be
received by Lessor on or before the Mid-Term Option Date or the End of Term
Option Date as appropriate.

     c.   The Mid-Term Option purchase price for the Property shall be
$74,135.35. The End of Term purchase price for the Property shall be the fair
market value of the Property at the time of such exercise as mutually agreed
upon by Lessor and Lessee.  If such parties cannot agree thereon after good
faith negotiation, the purchase price of the Property shall be the value
determined by an appraisal of the  Property made by a reputable independent
equipment appraiser certified for the type of Property being appraised.  The
appraiser shall be selected by Lessor and the cost of the appraisal shall be
paid by Lessee.

     d.   The Mid-Term Option purchase price shall only be applicable in the
event that the Mid-Term Option is exercised in accordance with its Terms.
Such purchase price shall not be deemed to be equal to the "anticipated
residual value" as such phrase is used in the Lease.

     e.   Upon receipt of payment of the purchase price together with any and
all applicable sales or other taxes due in connection therewith, and any and
all remaining sums or other amounts payable under this Schedule, Lessor shall
transfer all its right, title and interest in and to the Property to Lessee.
The Property shall be transferred "As Is" and "Where Is" without any express
or implied representations or warranties.

     f.   Should Lessee fail to either return the Property in accordance with
the Lease or exercise the End of Term Option in accordance with its terms, then
Lessor, at its sole option, shall have the right to: a) declare the End of Term
Option terminated and demand immediate return of the Property; or, b) extend the
Term for an additional six (6) months (the "Extended Term)".  Should Lessor
elect to extend the Term, Lessee shall be irrevocably obligated to remit basic
monthly rent for the period beginning on the day immediately succeeding the last
day of the original Term (the "Holdover Date" ) and ending at the end of the
sixth (6) month thereafter.  A payment of such rent being due on the Holdover
Date and on the same day of each consecutive month thereafter.  Each payment of
such rent shall be in the amount of the basic


<PAGE>

monthly rent for the last month of the Term in accordance with the provisions
of this Schedule.  All Lessee's other obligations under the Lease shall
remain in full force and effect for so long as Lessee shall continue to
possess the Property.  Upon the expiration of each Extended Term, Lessor, at
its sole option, shall have the right to:  a) permit Lessee to exercise the
End of Term Option in accordance with its Terms; b) declare the End of Term
Option terminated and demand immediate return of the Property; or, c) extend
the Term for an additional six (6) month Extended Term). Any and all  rental
payments pursuant to this Paragraph shall be deemed for all intents and
purposes to be payments for possession and use of the Property after the
expiration of the Term, and shall not be credited to any other obligation of
Lessee to Lessor.  Lessor's invoicing and/or accepting any such payment shall
not give rise to any right, title or interest of Lessee other than to
possession and use of the Property during the period to which such rent
applies in accordance with this Paragraph.  The aforsaid right to charge
Lessee rent for possession and use of the Property is not in limitation or
derogation of any of Lessor's rights pursuant to the Lease.

3.   MAINTENANCE, USE, AND RETURN PROVISIONS.  One hundred eighty (180) days
prior to return of the Property, and at any other time, in Lessor's discretion,
Lessee must be able to demonstrate that the Property can perform at its
performance specifications according to the manufacturer's standards.  An
independent certified technician chose by Lessor shall demonstrate the
performance of the property and the Property's physical condition.  If it is
determined that improvements are needed in order to meet the manufacturer's
performance standards, Lessee shall cause such improvements to be made at
Lessee's expense.  A certification letter from such technician as to the working
condition and performance of the Property shall be provided to Lessor.  The cost
of the technical inspection, assessment and certification shall be borne by
Lessee.

     Any special transportation devices, such as metal skids, lifting slings,
brackets, etc., which were with the Property when it originally arrived must be
used to assist with deinstallation and delivery.  Blocking of sliding members,
securing of swinging doors, pendants, and their swinging components, wrapping,
boxing, bending and labeling of all components  and documents must be done in a
conscientious and meticulous manner to facilitate the efficient reinstallation.
At no time are materials which would be considered "Hazardous Waste" by any
regulatory authority to be shipped with the machinery.  Replacement parts must
be purchased from sources approved by the original manufacturer.  No components,
tools or attachments are to be removed from the Property.


4.   DEPRECIATION.  Lessor will be entitled to modified accelerated cost
recovery depreciation based on 100% of Property Cost using the 200% declining
balance method, switching to straight line, for five (5)  year Property, and
zero salvage value.

5.   TAX INDEMNITY.  Lessee hereby represents, warrants, and covenants to Lessor
as follows:

     (a)  This Lease will be a lease for purposes of Oregon Revised Statutes
("ORS") 469.185-225.  Lessor will be treated as the purchaser, owner, lessor,
and original user of the Property and Lessee will be treated as the Lessee of
the Property for such purposes.

     (b)  Lessor Shall be entitled to the Business Energy Tax Credit ("BETC")
with respect to each item of Property as provided by ORS 469.185-225.  The
applicable BETC available to Lessor in connection with this Schedule is
$86,491.42.

     (c)  In the event that, pursuant to ORS 469.185-225, Lessee is deemed to
be the party eligible to receive the BETC, then Lessee irrevocably transfers
to Lessor all right, title and interest which Lessee has or may have to such
BETC and agrees to cooperate with Lessor in any manner necessary to ensure
that Lessor continue to receive the benefit of such BETC.

     If for any reason whatsoever any of the representations, warranties, or
covenants of Lessee contained in any other agreement relating to the Property
shall prove to be incorrect and (i) Lessor shall determine that it is not
entitled to claim all or any portion of the BETC in the amount specified (b)
above, or (ii) such BETC is disallowed, adjusted, recomputed, reduced, or
recaptured, in whole or in part, by the

<PAGE>

Director of the Oregon Department of Energy or his designee (such
determination, disallowance, adjustment, recomputation, reduction, or
recapture being herein called a "Loss"), then Lessee shall pay to Lessor as
an indemnity and as additional rent such amount as shall, in the reasonable
opinion of Lessor, cause Lessor's after-tax economic yield (the "Net Economic
Return") to equal the Net Economic Return that would have been realized by
Lessor if such Loss had not occurred.  The amount payable to Lessor pursuant
to this section shall be payable on the next succeeding rental payment date
after written demand therefor from Lessor, accompanied by a written statement
describing in reasonable detail such Loss and the computation of the amount
so payable.

     Further, in the event (i) there shall be any change, amendment, addition,
or modification of any provision of Oregon law or regulations thereunder or
interpretation thereof with respect to the matters set forth in this section
effective prior to the commencement date of the term of this Lease with respect
to any Property or (ii) if at any time there shall be any change, to the maximum
applicable BETC which results in a decrease in lessor's Net Economic Return,
then Lessor shall recalculate and submit to Lessee the modified rental rate
required to provide Lessor with the same net Economic Return as it would have
realized absent such change and the lease shall thereupon automatically be
deemed to be amended to adopt such rental rate and values.

     IN WITNESS WHEREOF, the Lessor and the Lessee have each caused this
Schedule to be duly executed as of the day and year first above written.
