2. Taxes: Any new tax, or other governmental charge, or increase thereof including increases in existing taxes, upon the production, sale and/or shipment of the Products sold under this Agreement (other than taxes based upon Seller’s net income), whether by federal, state or municipal authorities, imposed on or after the date of this Agreement, shall be added to the price then in effect hereunder and shall be paid to Seller by Buyer.

2

(*****) of the remaining contract quantity requirements hereunder, (*****) with equal terms and equal conditions resulting in lower delivered prices than the prices then in effect hereunder, then Buyer may give written notice to Seller. Upon giving written notice, Buyer agrees to provide satisfactory proof to Seller of the competitive offer. Satisfactory proof includes but is not limited to: (i) verification of the competitive written offer; (ii) disclosure of the company and manufacturing location(s) that would sell and produce the Product(s); (iii) analytical verification that Products to be supplied are of equal or better quality than the specification listed in Schedule I. After receiving both written notification and satisfactory proof of the written offer; Seller will have 30 days to provide written notification that it will either (i) match the competitive offer by providing pricing equal to the greater of the exact pricing during remaining term of the this contract or the average price over the total term of the competitive offer or (ii) provide an alternate proposal to the Buyer. If Seller elects to match the competitive offer as stated above the new pricing will be effective within thirty (30) days of that election. If Seller provides an alternate proposal, as stated above, Buyer will have (30) days to either accept or decline the alternate proposal. If the alternate proposal is accepted it would be added as an amendment to this contract and effective within thirty (30) days. If Buyer declines the alternate proposal then Seller will elect a time, no longer than one hundred and twenty (120) days from date the Buyer declines, at which both parties shall thereupon be released from any further obligation under this contract as to the Facilities encompassed by the competitive offer.

7B. Production Process Changes: Seller shall notify Buyer ninety (90) days prior to making any changes to Products, which will cause Products not to meet specifications listed in Schedule I or in Seller’s reasonable judgment will otherwise not be reasonably equivalent to Products produced prior to such change, and shall obtain Buyer’s agreement that such changes do not render the Products supplied hereunder unsuitable for Buyer’s use prior to instituting such changes.

7C. Quantity And Quality Requirements: Notwithstanding Buyer’s stated requirements for Product(s) herein, Buyer shall have the right to receive Product(s) from another supplier for the purpose of conducting “trial runs” within the time frame and quantities necessary to “test” the efficacy of Product(s) from another supplier, which trial runs shall not last for more than two weeks. Should Seller be unable to meet Buyer’s quantity and quality requirements, it shall be deemed a breach of this Agreement subject to the terms of Section 10. Upon a breach, Buyer may, upon written notice to Seller, reduce the allocation by the amount of Seller’s inability to ship, or cancel this Agreement without any obligation to Seller, if Seller cannot meet Buyer’s quantity and quality requirements upon written notice to Seller.

8. Fulfilling Production Requirements: Subject to Section 11, should Seller fail due to causes within Seller’s control to meet Buyer’s scheduled releases, provided they were previously forecasted in Schedule II, as mutually agreed to by both

3

parties, Seller shall take all reasonable steps, including but not limited to, working extra hours, shifts, or days to fulfill Seller’s obligations hereunder. All costs for such effort will be at Seller’s expense. Further, Seller may use alternate shipping methods to expedite delivery to Buyer to meet schedules to which both parties agree. In such cases, Seller must receive Buyer’s approval prior to the use of any carrier other than those on Buyer’s approved carrier list. Additional shipping costs resulting from expedited deliveries or use of alternate carriers will be at Buyer’s expense.

9A. Product Warranties:

(a) All claims relating to quality, quantity, weight, condition and loss of or damage to the Products contained in any delivery hereunder will be deemed waived by Buyer unless made in writing to Seller within thirty (30) days after acceptance of delivery by Buyer, unless such is not reasonably discoverable in which event within ten (10) days from actual discovery; provided, however, in any event all claims of Buyer will be deemed waived unless made in writing to Seller within 90 days of acceptance of delivery by Buyer.

(b) Except as stated in “Patents”, Seller warrants only its title to the Products and that the quality of the Product(s) shall conform to the Specifications. EXCEPT FOR THE WARRANTIES EXPRESSLY SET FORTH IN THIS AGREEMENT, ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE HEREBY EXCLUDED WHETHER THE ITEMS ARE USED ALONE, IN COMBINATION WITH, IN THE MANUFACTURE OF, OR IN THE PRODUCTION OF, OTHER SUBSTANCES, ITEMS, OR OTHERWISE. BUYER’S EXCLUSIVE REMEDY FOR BREACHES OF THIS WARRANTY SHALL BE REPLACEMENT OF THE NON-CONFORMING PRODUCT OR A PRICE ADJUSTMENT FOR THE SHIPMENT OF NON-CONFORMING PRODUCT.

10. Breach of Terms: In the event either party materially breaches any of the material terms of this Agreement or its extension(s), the non-breaching party shall notify the breaching party and the breaching party shall have thirty (30) days to correct the breach. If said breach is not remedied within such period, the non-breaching party shall then have the right to terminate this Agreement immediately upon written notice without further obligation to the breaching party.

11. Force Majeure: Seller’s failure or inability to make, or Buyer’s failure or inability to take, any delivery or deliveries when due, or the failure or inability of either party to effect timely performance of any other obligation required of it hereunder, other than the payment of money, if caused by “Force Majeure”, as hereinafter defined, shall not constitute a default hereunder or subject the party affected by Force Majeure to any liability to the other; provided, however, the party so affected shall promptly notify the other of the existence thereof and of its expected duration and the estimated effect thereon upon its ability to perform its obligations hereunder. Such party shall promptly

4

notify the other party when such Force Majeure circumstance has ceased to affect its ability to perform its obligations hereunder. The quantity to be delivered hereunder shall be reduced to the extent of the deliveries omitted for such cause or causes unless both parties agree that the total quantity to be delivered shall remain unchanged; and Buyer shall be free to purchase elsewhere any quantities Seller is unable to deliver due to such Force Majeure circumstance. For so long as its ability to perform hereunder is affected by such Force Majeure circumstances, Seller may, at its option, elect to allocate its total production of such Products among its various requirements therefore (e.g., manufacturing and sales) in such manner as Seller deems practicable and which, in the opinion of Seller, is fair and reasonable, with Seller giving consideration to it being the sole source of the Products for Buyer’s facilities covered by the Agreement. During the time that Seller is unable to make deliveries or otherwise perform, it shall not be obligated to procure, or to use its best efforts to procure, any quantity of Products sold hereunder from any alternate producer or supplier. As used herein, the term “Force Majeure” shall mean and include any act of God, war, riot, fire, explosion, accident, flood, sabotage, governmental laws, regulations, order, injunction, or other acts of government (including any agency or department of the United States of America), strikes, plant or equipment failure, lack of availability of materials, energy, labor, or equipment, and other circumstances beyond the reasonable control of the affected party. In the event a Force Majeure circumstance affects either party’s performance hereunder for at least 60 consecutive days, the party who is able to perform may terminate this Agreement upon written notice to the affected party.

12. Fair Labor Standards Act: Seller agrees that the materials produced hereunder shall be in compliance with all acceptable requirements of the Fair Labor Standards Act of 1938, as amended, and of Regulations and Orders of the United States Department of Labor issued under Section 14 thereof and agrees to so certify on its invoices if so directed by Buyer.

13A. Patents: Seller warrants that the Products shall be delivered free of the rightful claim of any third person for infringement of any U.S. patent covering the Products. Seller does not warrant against infringement by, and assumes no responsibility by reason of, the use of the Products in combination with other materials or apparatus or in the operation of any process or apparatus. Seller disclaims any warranty against infringement to the extent that the Products are supplied according to Buyer’s design or specifications.

In the event of the commencement of any suit or proceeding against Buyer for infringement covered by the above warranty, Buyer shall notify Seller promptly, in writing, of the commencement of such suit or proceeding. Seller shall indemnify, hold harmless, and defend Buyer with respect to such suit or proceeding in Buyer’s name; and Buyer will render to Seller all reasonable assistance for the defense or settlement thereof. Buyer shall not settle or compromise any such suit or proceeding without the prior written consent of Seller.

14. WAIVER OF CONSEQUENTIAL DAMAGES: IN NO EVENT WILL SELLER OR BUYER BE LIABLE UNDER ANY THEORY OF RECOVERY (WHETHER BASED IN CONTRACT, NEGLIGENCE OF ANY KIND, STRICT LIABILITY OR TORT) FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, INCLUDING LOST PROFITS, IN ANY WAY RELATED, ARISING FROM OR RESULTING FROM THIS AGREEMENT. A PARTY’S EXCLUSIVE REMEDY SHALL BE DIRECT DAMAGES OR SPECIFIC PERFORMANCE FOR A MATERIAL BREACH OF ANY TERM OR CONDITION OF THIS AGREEMENT BY THE OTHER PARTY.

15. Waiver: The failure of either party to enforce at any time any of the provisions of this Agreement shall in no way constitute or be construed as a waiver of that or any other provision of this Agreement, nor in any way to affect the validity of this Agreement or any provision hereof or the right of such party to enforce thereafter each and every provision of this Agreement. No waiver of any provision or breach of this Agreement shall be deemed to be a waiver of any other provision or breach.

16. Governing Law: Any dispute under this Agreement shall be first settled by and between the managements of both parties, and if such dispute cannot be resolved within 30 days of written notice of such dispute by either party to the other party, then settled by arbitration in Chicago, IL within 90 days of the expiration of such management discussion period, pursuant to the rules, then obtaining, of the American Arbitration Association. The award shall be final and judgment thereon may be entered in and enforced in any court having jurisdiction. The arbitrator shall apply Delaware law, without giving effect to principles of conflicts of laws and may not vary the terms of this Agreement or impose any remedy not allowed under this Agreement.

17. Notices: Any notice given under this Agreement shall be in writing and addressed to the other party at the address specified in this paragraph. Notice may be given by U.S. mail (first class or certified), any personal delivery service, fax, or telex. Any notice required or permitted hereunder shall be deemed given upon the earlier of (i) the day of actual receipt by the party to whom notice is being given or the following business day if actual receipt is during a non-business day of the receiving party or is after regular business hours on a business day of the receiving party, or (ii) the fourth day after being deposited postage prepaid in the U.S. Mail as first class mail.
