ARTICLE 7
POST CLOSING COVENANTS

The Seller and the Buyer hereby covenant and agree as follows:

7.1 Confidentiality.

(a) Each party shall maintain in strict confidence all Confidential Information and disclose such Confidential Information only (A) to its employees and duly authorized agents and representatives who have been informed of the obligations of the parties under this Agreement with respect to such Confidential Information, who have a need to know information in connection with consummating the transactions contemplated herein, and who agree to keep such information confidential, or (B) as required by legal process (of which the other party shall be given prompt notice). The party receiving Confidential Information (as used in this Section, "receiving party") shall be responsible for any breach of this Section 7.1 with respect to such Confidential Information by any of its representatives and agrees to take all reasonable measures to restrain its representatives from prohibited or unauthorized disclosure of the Confidential Information. For the purpose of this Section 7.1(a), the term "Confidential Information" shall mean information that (i) with respect to the Buyer, relates directly and solely to the Business, the Purchased Assets, the ▇▇▇▇▇ Records or the Assumed Liabilities, and with respect to the Seller, relates directly and solely to the Common Records, and (ii) is the subject of efforts that under the circumstances are reasonable to maintain its confidentiality; provided however "Confidential Information" shall not mean (A) information generally available to the public which has not become available as a result of disclosure in violation of this Section 7.1, (B) information which becomes available on a nonconfidential basis from a source other than the receiving party or its representatives, provided that such source is not known by the party to this Agreement receiving such information to be bound by a confidentiality agreement or other obligation of secrecy to another party to this Agreement or its representatives and (C) information that was or is developed by the receiving party independently of and solely without reference to any Confidential Information.

(b) No press release, public announcement, confirmation or other information regarding this Agreement or the contents hereof shall be made by the Buyer or the Seller without prior consultation with the Buyer and the Seller, except as may be necessary in the opinion of counsel to any party to meet the requirements of any applicable law or regulations (including, without limitation, disclosure requirements in connection with securities laws and regulations or exchange rules) or the determination of any court.

7.2 Expenses. Except as otherwise expressly provided in this Agreement, each of the parties hereto shall assume and bear all expenses, costs and fees incurred or assumed by such party in the preparation and execution of this Agreement and in compliance with and performance of the agreements and covenants contained in this Agreement. Without limiting the generality of the foregoing, Seller shall be responsible and shall pay all costs and expenses associated with ▇▇▇▇▇▇ Consulting, Inc.

7.3 Agreement to Not Compete. In consideration of the Purchase Price, the Seller agrees that, effective as of the date hereof and for a period of sixty (60) months hereafter (the "Non-Compete

Term"), neither the Seller nor any of its Affiliates shall, without the consent of the Buyer, directly or indirectly own, engage in, manage, operate, join, control, finance or participate in the ownership, management, operation, control or financing of, or be connected as an employer, principal, agent, representative, consultant, investor, owner (including shareholder), lender, partner, manager, joint venturer or otherwise with, or permit its or its Affiliates' names to be used by or in connection with (i) the Business conducted by the Seller (except with respect to the Ravap Products) and (ii) the development, manufacturing, processing, storage, distribution, sale marketing, use and licensing of oral larvicides in the United States.

7.4 Non-Interference with Relationships. During the Non-Compete Term, the Seller shall not directly or indirectly, to the extent related to the Business:

(a) (i) call upon, canvass, solicit or transact, or attempt to call upon, canvass, solicit or transact, business with any customer of the Buyer (except with respect to the Ravap Products), or (ii) advise customers or suppliers of the Seller to withdraw, curtail or cancel business with the Buyer; or

(b) (i) render services related to the Business to or for competitors of the Buyer, or (ii) supply sales, financial, manufacturing, design, marketing, engineering or technical information with respect to the Business to third parties.

7.5 Specific Performance. The Seller acknowledges and agrees that any breach of the restrictive covenants set forth in Sections 7.3 and 7.4 hereof will result in irreparable damage to the Buyer for which there will be no adequate remedy at law, and the Seller consents to an injunction, issued by any court of competent jurisdiction, in favor of the Buyer, enjoining any breach of such covenant, without prejudice to any other right or remedy to which the Buyer may be entitled. In the event that any part of Sections 7.3 and 7.4 herein is determined by any court of competent jurisdiction to be unenforceable by reason of its being extended for too great a period of time or too large a geographic area or over too great a range of activities, that section is to be interpreted to extend only over the maximum period of time, geographic area or range of activities required to render it valid and enforceable.

7.6 Testing Costs Reimbursement. Seller is now responding to a Reauthorization Eligibility Document for tetrachlorvinphos that was issued in 1995 by the EPA. A revised risk assessment that incorporated the requirements of the Food Quality Protection Act of 1996 was conducted in 1997-99. The EPA required additional residue chemistry studies on poultry, swine and cattle to confirm that residues of tetrachlorvinphos and four metabolites were at acceptable dietary levels. These studies were requested in December 1999. To the extent that the aggregate out-of-pocket testing cost of any residue testing incurred by Buyer as part of satisfying such reregistration of the ▇▇▇▇▇ Products, plus any related administrative out-of-pocket costs, exceeds $250,000.00, Seller will pay for or reimburse such costs on Buyer's behalf promptly upon receipt of an invoice from Buyer, up to an aggregate total of $1,000,000.00, which invoice shall contain evidence that such costs were incurred and satisfied by payment to a third party. The provisions of this Section 7.6 are not subject to the limitations of Sections 8.6.

7.7 Subregistrations. Immediately following the approval of the transfer to Buyer of the registrations for the ▇▇▇▇▇ Products by the EPA, Buyer shall deliver to the Seller the executed counterpart of an agreement under which Buyer subregisters to Seller the right to sell Ravap E.C. Livestock, Poultry & Premise Insecticide Spray, substantially in the form attached hereto as Exhibit G (the "Subregistration Agreement").

7.8 Diflubenzuron Agreement. As soon as practicable after the Closing, Seller shall use its commercially reasonable best efforts to take all such action as is reasonably necessary to assist Buyer without additional cost or liability to Buyer in securing the consent of Crompton Sales Company, Inc. to the assignment of that certain Distribution and Formulation Agreement dated June 1, 2001. Upon

such consent, each of Seller and Buyer shall promptly execute and deliver the Assignment and Assumption Agreement attached hereto as Exhibit H, which assignment shall include all data and other information developed by the parties to the Crompton Sales Agreement in connection with the performance of such agreement.

7.9 Trademark License. Seller recognizes the need to allow Buyer, during the pendency of the transfer of ▇▇▇▇▇ Products registrations contemplated by this Agreement, to use certain trademarks of Seller as are currently included on labels of ▇▇▇▇▇ Products, including: BOEHRINGER INGELHEIM, BOEHRINGER INGELHEIM VETMEDICA, INC. and related trademark designs ("BI Trademarks"). Seller hereby grants to Buyer, subject to and in compliance with all other terms and conditions of this Agreement, a non-exclusive license to use the BI Trademarks for a period of one year following the Closing solely in connection with (i) printing labels that conform to the EPA registrations for ▇▇▇▇▇ Products, and (ii) affixing such labels to ▇▇▇▇▇ Products that conform to the EPA registrations therefor. Upon reasonable request of Buyer, Seller will extend the term of the license granted under this Section 7.9 in up to two successive six-month increments with respect to ▇▇▇▇▇ Products for which the EPA has not transferred registration at the time of such request. Buyer agrees that it will do nothing inconsistent with Seller's ownership of the BI Trademarks, and that all use of the BI Trademarks and all goodwill developed therefrom shall inure to the benefit of and be on behalf of Seller. Buyer agrees that nothing in this clause shall give Buyer any right, title, or interest in the BI Trademarks other than the right to use the BI Trademarks in accordance with this Section 7.9. Buyer agrees that it will not attack the title of Seller to the BI Trademarks or attack the validity of this clause. Buyer is prohibited from entering into any sublicenses of its rights under this Section 7.9 to any other third party without the consent of Seller, which consent shall not be unreasonably withheld. Seller hereby consents to the sublicense by Buyer of any and all of Buyer's rights under this Section 7.9 to PM Resources.

ARTICLE 8
EXTENT AND SURVIVAL OF REPRESENTATIONS,
WARRANTIES, COVENANTS AND AGREEMENTS; INDEMNIFICATION

8.3 Indemnification Procedure. Any party seeking information or reimbursement for Claims hereunder (the "Indemnified Party") shall as promptly as practical notify the party from which such indemnification is sought (the "Indemnifying Party") upon which the Indemnified Party intends to base a claim for indemnification or reimbursement hereunder; provided, however, that the failure of an Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability under this Agreement to the Indemnified Party with respect to such Claim except to the extent the Indemnifying Party is actually prejudiced or damaged by the failure to receive timely notice. In the event of any claims for indemnification or reimbursement, the Indemnifying Party, at its option, may assume (with legal counsel reasonably acceptable to the Indemnified Party) the defense of any claim, demand, lawsuit or other proceeding brought against the Indemnified Party, which claim, demand, lawsuit or other proceeding may give rise to the indemnity or reimbursement obligation of the

Indemnifying Party hereunder, and may assert any defense of any party; provided, however, that the Indemnified Party shall have the right at its own expense to participate jointly with the Indemnifying Party in the defense of any claim, demand, lawsuit or other proceeding in connection with which the Indemnified Party claims indemnification or reimbursement hereunder. Notwithstanding the right of an Indemnified Party so to participate, the Indemnifying Party shall have the sole right to settle or otherwise dispose of such claim, demand, lawsuit or other proceeding on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate with respect to any issue involved in such claim, demand, lawsuit or other proceeding as to which (i) the Indemnified Party shall have acknowledged the obligation to indemnify the Indemnified Party hereunder and the settlement is solely for cash or (ii) the Indemnified Party shall have declined so to participate.

8.4 Survival. All representations and warranties of the parties hereto shall survive the date hereof and shall remain in full force and effect for a period of eighteen (18) months, except for Sections 5.2, 5.7 and 5.8 which shall continue until the expiration of the applicable statute of limitations. All representations, warranties and covenants and agreements made by the parties shall not be affected by any investigation heretofore or hereafter made by and on behalf of any of them and shall not be deemed merged into any instruments or agreements delivered in connection with the transactions contemplated hereby. The covenants and agreements entered into pursuant to this Agreement shall survive the date hereof without limitation (subject to the applicable statutes of limitations).

8.5 APPLICABILITY OF INDEMNIFICATION OBLIGATION. EACH OF THE AGREEMENTS TO INDEMNIFY, DEFEND OR HOLD HARMLESS CONTAINED IN SECTION 8.2 OR 8.3 SHALL APPLY IRRESPECTIVE OF WHETHER THE SUBJECT CLAIM IS BASED IN WHOLE OR IN PART UPON THE SOLE OR CONTRIBUTORY NEGLIGENCE (WHETHER ACTIVE, PASSIVE OR GROSS), BREACH OF COVENANT, OR BREACH OR VIOLATION OF ANY DUTY IMPOSED BY ANY LAW OR REGULATION, ON THE PART OF THE BENEFICIARY OF THE AGREEMENT, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT.

8.6 Limitation on Amounts. No Indemnified Party shall be entitled to any indemnification until the aggregate dollar amount of all Claims suffered by the Indemnified Party reaches Fifty Thousand Dollars ($50,000.00); provided, however, that the Indemnified Party shall then be entitled only to those amounts exceeding $50,000.00 once that amount is exceeded. Notwithstanding any other provisions contained in this Agreement, the maximum amount that may be recovered by an Indemnified Party under this Article 8 or otherwise shall be One Million Nine Hundred and Ten Thousand Dollars ($1,910,000.00). In no event shall this section apply to the obligations of the Buyer under Article 2 or Seller under Section 7.6.

8.7 Effect of Insurance. Any Claim for which an Indemnifying Party is liable shall be reduced (including, without limitation, retroactively) by any insurance proceeds actually recovered that directly relate to the Claims for which indemnification is sought.

8.8 Sole Remedy. The Buyer and the Seller acknowledge and agree that in the absence of fraud, gross negligence or intentional misconduct, the foregoing indemnification provisions in this Article 8 shall be the sole and exclusive remedy at equity and law of the Buyer and the Seller with respect to this Agreement, provided that this provision shall not affect the rights and remedies of the parties under the Contract Manufacturing Agreement.
