                                    RECITALS


WHEREAS, WTI is a manufacturer and supplier of clean room and contamination
control products used for specialized applications in the electronics and
medical device industries;

WHEREAS, TRS is a manufacturer of high density hydrophilic foam;

WHEREAS, WTI desires to purchase such hydrophilic foam material from TRS; and

WHEREAS, TRS wishes to supply WTI's requirements of the hydrophilic foam
material.

NOW THEREFORE, the parties hereto agree as follows:

1.0      DEFINITIONS.

         1.1 Minimum Annual Quantity shall mean the minimum annual quantity of
the Products and the Additional Products which WTI is obligated to purchase from
TRS as set forth on Exhibit A attached hereto. The Minimum Annual Quantities of
the Product shall include purchases of the Product by TMP Technologies, Inc.
("TMP") when used by TMP in manufacturing products sold to WTI. If the price per
board foot of the Product sold to TMP is different from the price referenced in

specifications attached to this Agreement as Exhibit B.

2.0      TERM.

         2.1 The term of this Agreement shall be for a period of three (3) years
commencing on the Effective Date above and ending automatically at the
expiration of this period.

         2.2 If WTI and TRS expressly agree in writing to renew this Agreement
prior to the foregoing expiration date, this Agreement shall continue in full
force and effect for one or more successive one (1) year renewal periods.

3.0      SUPPLY AND PURCHASE.

         3.1 WTI agrees that it will purchase the Minimum Annual Quantities. In
the event that WTI fails to purchase the Minimum Annual Quantity in a particular
year, TRS shall be entitled to convert this Agreement to a nonexclusive supply
agreement (and Section 3.3 below shall be rendered null and void). Conversion to
nonexclusivity will constitute TRS' exclusive remedy for WTI's failure to
purchase the Annual Minimum Quantity in a particular year (and WTI will not be
held to any further minimum purchase requirement following such conversion).

         3.2 TRS will use its best efforts to supply the Minimum Annual
Quantities and any additional quantities forecasted by WTI pursuant to Section 4
below.

         3.3 TRS agrees that it will not supply the Product to any other
customer which manufactures and/or sells products for clean room and/or
contamination control markets during the term of this Agreement. TRS agrees that
it will not supply the Product to any other customer which manufactures and/or
sells products for clean room and/or contamination control markets for a period
of six (6) months following the termination or expiration of this Agreement,
provided that WTI has purchased 80% or more of the Minimum Annual Quantities in
the year immediately preceding the date of termination.

4.0      PURCHASE ORDERS/FORECASTS

         During the first week of each month, WTI shall forward to TRS a three
(3) month rolling forecast of Product and Additional Product requirements
designating the quantities of the Product and the Additional Product which WTI
intends to sell in such period. Product and Additional Product requirements
scheduled for delivery in months 1 and 2 of the rolling forecast will be
considered firm orders and may not be rescheduled or canceled by WTI.

                  b. combinations of the Product or the Additional Product with
                  another product not furnished hereunder unless TRS is a

                  written consent.
