         3.1 During the term of this Agreement, Polymers agrees to manufacture
and sell to Buyer and Buyer agrees to buy its and its Affiliates entire
requirements of the Units from Polymers upon the terms and conditions set forth
in this Agreement. In the event that Polymers is unable for any reason,
including production capacity of molds, to produce a Unit or Units in sufficient
volume to satisfy the Buyer's requirements for such Units and is unable to cure
such inability within thirty (30) days plus reasonable mold development and
applicable raw material lead-in times, Buyer shall have the option to utilize
another manufacturer to manufacture the Units required in excess of Polymers
production capacity if Polymers is unable or unwilling to within a reasonable
period of time to subcontract out the manufacturing of any Units required in
excess of Polymers production capacity. Polymers and Buyer shall discuss and
agree upon mutually acceptable minimum amounts of Units to be purchased
hereunder from time to time during the term hereof.

         3.2 The Units to be purchased under this Agreement are specifically
detailed and described in EXHIBIT A, which is attached hereto and incorporated
herein by reference. In the event the provisions of Section 17 hereof are
satisfied, such new product shall be added to EXHIBIT A, and shall become a

materials costs, rent, custom charges, state taxes, import or export fees,
freight costs, or utility rates, Polymers shall provide Buyer documentation
supporting such cost increases in a form reasonably satisfactory to Buyer. Upon
Buyer's reasonable satisfaction and confirmation of the increased manufacturing
costs, not to exceed thirty (30) days from Buyer's receipt of such
documentation, the increased costs shall be "passed through" to Buyer on a per
Unit basis to be determined by Buyer and Polymers, with such increase to reflect
a direct pass through of such increased manufacturing costs. For the purpose of
this Section 4.2, manufacturing costs shall be examined on six (6) month
intervals, with the first such examination to occur on August 1, 1995.

         4.3 In the event manufacturing costs decrease, Polymers shall inform
Buyer of such decrease and shall negotiate with the Buyer, in good faith, a
reduction in the Purchase Price of each Unit. The decreased costs shall be
"passed through" to Buyer on a per Unit basis to be determined by Buyer and
Polymers, with such decrease to reflect a direct pass through of such decreased
manufacturing costs. For the purposes of this Section 4.3, manufacturing costs
shall be reviewed on six (6) month intervals with the first such examination to
occur on August 1, 1995.

         4.4 All prices are expressed and all payments shall be made in U.S.

                          PART V. TERM AND TERMINATION

SECTION 18.   TERM OF THE AGREEMENT

         18.1 The term of this Agreement shall commence on September 1, 1997 and
shall expire on August 31, 2002, provided that Buyer shall have the option to
renew this Agreement for five additional periods of one year each. Buyer shall
provide Polymers one hundred eighty (180) days notice of its intention to
exercise the extension option.

         18.2 Either Buyer or Polymers may end this Agreement at any time
without further obligation to the other party pursuant to Section 20,
"CANCELLATION FOR DEFAULT."

SECTION 19.   CANCELLATION FOR DEFAULT

         19.1 Upon the Buyer delivering to Polymers written notice specifying
the nature of Polymers' default and the expiration of ninety (90) days following
that delivery of that notice of default without Polymers curing that default
then, and only then, shall Buyer have the right to terminate or cancel this
Manufacturing Agreement. A "default" with respect to Polymers, shall mean that
Polymers:

         (a)  Becomes insolvent or has a petition in bankruptcy, reorganization 
or similar action filed by or against it;

         (b)  Is unable to produce the Units in sufficient volume as required by
this Agreement or maintain the quality control levels specified pursuant to
Section 6 of this Agreement.

         (c)  Has all or a substantial portion of its capital stock or assets 
expropriated or attached by any government entity;

         (d)  Is dissolved or liquidated or has a petition for dissolution or 
liquidation filed with respect to it;


<PAGE>   10



         (e)  Is subject to property attachment, court injunction, or court 
order materially affecting its operations under this Agreement; or

         (f)  Materially breaches any representation, warranty, covenant or 
other agreement contained in that certain Asset Purchase Agreement by and among
NSA Polymers, Inc., NSA International, Inc. and Polymers dated of even date
herewith or any document which is an exhibit thereto or defaults in the payment
of any amounts owed to NSA Polymers, Inc. as a result of such Asset Purchase
Agreement or any document which is an exhibit thereto.

         19.2 Upon Polymers delivering to Buyer written notice specifying the
nature of Buyer's default and the expiration of ninety (90) days following that
delivery of that notice of default without Buyer curing that default then and
only then shall Buyer have the right to terminate or cancel this Manufacturing
Agreement. A default with respect to Buyer shall mean that NSA International,
Inc.:

         (a)  Becomes insolvent or has a petition in bankruptcy, reorganization 
or similar action filed by or against it;

         (b)  Has all or a substantial portion of its capital stock or assets 
expropriated or attached by any government entity;

         (c)  Is dissolved or liquidated or has a petition for dissolution or 
liquidation filed with respect to it; 

         (d)  Is subject to property attachment, court injunction, or court 
order materially affecting its operations under this Agreement; or

         (e)  Fails to pay any amount due pursuant to the terms of this
Agreement, provided, however that if Buyer is in good faith contesting any
amount owed to Polymers as a result of this Agreement through appropriate
proceedings, such failure to pay shall not be considered an event of default
under this Agreement;

         19.3 In the event of a default and the lapse of any applicable cure
period, the non-defaulting party may agree to continue the Agreement rather than
cancelling it. To do so, that party shall send a notice to the defaulting party
specifying the conditions under which the non-defaulting party will agree to
continue the Agreement. By agreeing to continue the Agreement in this manner,
the non-defaulting party does not waive its right to later cancel the Agreement
for default based on the event of default that is the subject of the notice.

         19.4 If Polymers cancels this Agreement for default by Buyer, Buyer
shall pay Polymers all payments for work completed, if it was in response to a
Purchase Order, on the effective date of cancellation. In the event of such a
cancellation, Polymers shall have the right to offset, against payments due
pursuant to those certain promissory notes between Polymers and the Buyer in the
principal amounts of $500,000 and $4,000,000 the amounts of liquidated damages,
calculated in accordance with the provisions of Section 16 which are due from
the Buyer to Polymers, on the dates that such liquidated damages accrue pursuant
to the terms of Section 16.

         19.5 If Buyer cancels this Agreement for default by Polymers Buyer
shall pay Polymers the Purchase Price for all Units and work completed in
accordance with this Agreement. Additionally, Buyer shall pay to Polymers,
Buyer's actual costs for any raw materials or components ordered in response to
a purchase order or work-in-process. Polymers shall deliver to Buyer all
documents, information, and work in process produced in performance of this
Agreement. In the event that Buyer cancels this Agreement for default by
Polymers, Buyer shall have no obligation to pay any amounts of liquidated
damages to Polymers, other than those liquidated damages which have accrued
prior to the date upon which this Agreement is terminated.

SECTION 20.   CANCELLATION OF PURCHASE ORDERS

         20.1 Buyer may cancel Purchase Order(s) or any portions thereof for any
reason by notifying Polymers in writing fifteen (15) days prior to the scheduled
delivery date. Cancellation shall be effective upon Polymers


<PAGE>   11

 

receipt of the written cancellation notice from Buyer, or thereafter upon the
date specified in such cancellation notice. Polymers shall cease operation on
subject Purchase Orders in accordance with the cancellation notice and shall
make every reasonable effort to cancel commitments for, resale of or divert
materials and/or work-in-process (with the exception of the case such resale or
diversion infringes Buyer's rights under this Agreement).

         20.2 In the event of a cancellation of a Purchase Order under this
Section, Buyer will pay Polymers the Purchase Price for completed Units and
shall reimburse Polymers for its actual costs for raw materials, components, and
work-in-process as a result of the cancelled purchase order. Polymers will
deliver to Buyer all completed Units and work-in-process procured on account of
the cancelled Purchase Order(s).

SECTION 21.   EXCUSABLE DELAYS

         21.1 Neither party shall be in default or liable to the other for any
failure to perform directly caused by events beyond that party's reasonable
control, such as acts of nature, labor strikes, war, insurrections, riots, acts
of governments, embargoes and unusually severe weather provided the effected
party notifies the other party within ten (10) days of the occurrence. Such an
event is an Excusable Delay. THE PARTY EFFECTED BY AN EXCUSABLE DELAY SHALL TAKE
ALL REASONABLE STEPS TO PERFORM DESPITE THE DELAY. If the party is unable to
perform within a reasonable period, this Agreement shall end without any further
obligation of the unaffected party.

SECTION 22.   RETURN OF MATERIALS AND RIGHT OF ENTRY

         22.1 Unless otherwise notified by Buyer, within one month of the date
of expiration, termination or cancellation of this Agreement, upon payment of
all amounts owed to Polymers other than any liquidated damages accruing in the
future, Polymers shall return to Buyer all materials containing Buyer
Confidential Information or Technical Information, documents produced in the
performance of this Agreement, work-in-process, molds, parts, tools and test
equipment paid for, owned or supplied by Buyer at Buyer's expense.

         22.2 In the event of termination of this Agreement by either party,
upon payment of all amounts owed to Polymers other than any liquidated damages
accruing in the future, Buyer shall have the immediate right to enter Polymers
premises and take possession of all Buyer owned tooling or property, to file a
security interest in such tooling or property or to invoke any other legal or
equitable remedy available to protect its interest in the tooling or property.

Claims, or Encumbrances.

         24.2 Polymers shall maintain comprehensive general liability insurance
for claims for damages because of bodily injury or death and property damage
caused by or arising out of acts or omissions of its employees. Polymers shall
not cancel the insurance without notifying Buyer in writing in advance.

         25.1 Polymers will, at Polymers' expense, maintain product liability
insurance in such amounts, against such risks, in such form as historically
maintained by NSA Polymers, Inc.

         25.2 Each such policy shall (a) name Buyer and Polymers as additional
insured parties thereunder (without any representation or warranty by or
obligation upon Buyer) (b) and provide that at least thirty (30) days prior
written notice of cancellation, amendment, or of lapse shall be given to Buyer
by the insurer.

such insurance, or satisfactory certificates of insurance.
