RESTRICTIONS ON TRANSFER; THE SECURITIES ACT OF 1933. 7.1 RESTRICTIVE LEGENDS. The Securities shall not be transferable except upon the conditions specified in this Article 7 and, with respect to the Notes, the restrictions contained in Section 4.1 and the Indenture, which conditions are intended to insure compliance with the provisions of the Securities Act in respect of the transfer of any such Securities and, with respect to the Series A Shares, upon the conditions specified in Article 3 of the Investors Agreement and in the Share Price Adjustment Agreement. Each Purchaser and each Designee hereby acknowledges and agrees that it is acquiring the Securities in a transaction exempt from registration under the Securities Act and that no Security may be offered, sold, pledged or otherwise transferred in the absence of registration under the Securities Act or an applicable exemption therefrom. Each of the Securities shall (unless otherwise permitted by the provisions of this Article 7) be stamped or otherwise imprinted with a legend in substantially the following form: "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD IN THE ABSENCE OF REGISTRATION THEREUNDER OR AN APPLICABLE EXEMPTION THEREFROM." In addition to any other legend that may be required, each certificate for the Notes shall be stamped or otherwise imprinted with a legend in substantially the following form: "THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE ISSUER THAT (A) THIS NOTE MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (i) INSIDE THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (ii) OUTSIDE THE UNITED STATES IN A TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (iii) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT 10 PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (iv) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (i) THROUGH (iv) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE." In addition to any other legend that may be required, each certificate for Series A Shares shall be stamped or otherwise imprinted with a legend in substantially the following form: "THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE INVESTORS AGREEMENT DATED AS OF OCTOBER 16, 1998, AS AMENDED FROM TIME TO TIME, COPIES OF WHICH MAY BE OBTAINED UPON REQUEST FROM ENVIROSYSTEMS CORP. AND ANY SUCCESSOR THERETO." 7.2 NON-APPLICABILITY OF TRANSFER RESTRICTIONS; REMOVAL OF LEGENDS. The restrictions imposed by Section 7.1 above upon the transferability of any Series A Share represented by a certificate bearing the restrictive legends set forth in such Section 7.1 (a "Restricted Security") shall cease and terminate when such Restricted Security has been sold pursuant to an effective registration statement under the Securities Act or transferred pursuant to Rule 144 (or any similar or successor rule thereto) promulgated under the Securities Act unless the holder thereof is an affiliate of the Parent. The holder of any Restricted Security as to which such restrictions shall have terminated shall be entitled to receive from the Parent, without expense, a new security of the same type but not bearing the restrictive legend set forth above and not containing any other reference to the restrictions imposed by Section 7.1 above, PROVIDED that a holder's right to receive, and the Parent's obligation to issue, a new Security not bearing such restrictive legends and not containing any other reference to the restrictions imposed by Section 7.1 above shall be subject, in the Parent's discretion, to the delivery to the Parent of an opinion of counsel of the transferor (which may include in-house counsel to any Purchaser) that subsequent transfers of such Restricted Security by the proposed transferee will not require registration under the Securities Act. As used in this Section 7.2, the term "transfer" encompasses any sale, transfer, pledge or other disposition of any Securities referred to herein. 11 8. EXPENSES, ETC. (a) The Company or the Parent agrees to reimburse the Purchasers for all reasonable out-of-pocket expenses (including without limitation the reasonable fees and expenses of one counsel for each Purchaser) of the Purchasers incurred in connection with the Transactions, unless this Agreement is terminated prior to the consummation of the Transactions as a result of a breach of this Agreement by the Purchasers. (b) Subject to the provisions of the next sentence of this Article 8, each of the Company and the Parent agrees to pay, and hold the Purchasers harmless against liability for the payment of, all stamp and other similar taxes (together in each case with interest and penalties, if any) which may be payable in respect of the execution and delivery of this Agreement, the Indenture, the Investors Agreement and the Registration Rights Agreement, if any, or the issuance, delivery or acquisition by the Purchasers of any Notes or Series A Shares pursuant to this Agreement and the Indenture, other than any transfer taxes applicable to any transfer between a Purchaser and a subsequent holder of the Notes or Series A Shares (other than the Company or the Parent), and reasonable fees and expenses incurred by each Purchaser in connection with any filing by the Company or the Parent with any governmental agency with respect to the Company or the Parent that mentions such Purchaser. Each of the Company and the Parent additionally agrees to pay, and hold each Purchaser harmless against liability for the payment of, all out-of-pocket expenses with respect to the enforcement by such Purchaser of any provision of any agreement or instrument referred to in this Article 8 plus the Registration Rights Agreement and the Investors Agreement and any proposed amendments or waivers (whether or not the same shall be signed or become effective) under or in respect of any such agreement or instrument, PROVIDED that in each case the Company or the Parent has been or, without such amendment or waiver, would be in default in respect of its obligations thereunder. (c) The obligations of the Company and the Parent in this Article 8 shall be of full force and effect whether or not any Notes or Series A Shares are sold hereunder (unless the failure of any Notes or Series A to be sold hereunder is due to a breach of, or default under, this Agreement by a Purchaser or Designee) or the Closing ever takes place and such obligations shall also survive the payment for or transfer of any of the Notes or Series A Shares, the enforcement of any provisions of any agreement or instrument referred to in this Article 8 and any amendments or waivers with respect thereto. 12 9. INDEMNIFICATION OF PURCHASERS. In addition to all other sums due hereunder or provided for in this Agreement, each of the Issuers, jointly and severally, will indemnify and hold harmless each Purchaser (which term for purposes of this Article 9 includes any agent of or any person controlling each such Purchaser) from and against any losses, claims, damages, liabilities, costs and expenses (including reasonable attorneys' fees) incurred by it pursuant to any investigation or proceeding instigated or brought by any governmental or administrative entity or other person against the Parent, the Company or such Purchaser arising out of or in connection with this Agreement (including the Offering Memorandum or any other document or instrument delivered in connection herewith), except to the extent that such losses, claims, damages, liabilities, costs and expenses resulted primarily from any wrongful action on such Purchaser's part which was not taken by such Purchaser in reliance upon any of the warranties, covenants or promises of any of the Issuers herein or the documents contemplated hereby or the certificates delivered by any of the Issuers pursuant hereto or thereto, whether or not the transactions contemplated by this Agreement are consummated, which investigation or proceeding requires such Purchaser's participation or is commenced or filed against such Purchaser because of this Agreement or the transactions contemplated hereby. The obligations of the Issuers under this Article 9 shall survive the payment or prepayment of the Notes and the Series A Shares, at maturity, upon redemption or otherwise. Promptly after receipt by an indemnified party under this Article 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Article 9, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Article 9. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party (which consent shall not be unreasonably withheld), be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Article 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of 13 any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action. No indemnified party may effect any settlement or compromise of any pending or threatened action in respect of which such indemnified party has sought or may seek indemnification hereunder without the prior written consent of each indemnifying party. 10. CONTRIBUTION. If the indemnification provided for in Article 9 is unavailable or insufficient to hold harmless an indemnified party under Article 9, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities, costs and expenses referred to in Article 9 in such proportion as is appropriate to reflect the relative fault of the Issuers on the one hand and the Purchaser on the other in connection with the actions which resulted in such claim as well as any other relevant equitable considerations. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in this paragraph shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim. The obligations of the Issuers under Articles 9 and 10 shall be in addition to any liability which the Issuers may otherwise have and shall extend, upon the same terms and conditions, to each Purchaser, its representatives, officers and directors and each person, if any, who controls such Purchaser within the meaning of the Securities Act or the Exchange Act. 11. COUNTERPARTS. This Agreement may be executed in one or more counterparts, but all such counterparts shall constitute one and the same instrument. 12. SURVIVAL OF COVENANTS, ETC.; SUCCESSORS AND ASSIGNS. All covenants, agreements, representations and warranties made by the parties in this Agreement or incorporated by reference herein and in certificates or other documents delivered pursuant to it shall remain in full force and effect, regardless of any investigation or statement as to the results thereof, made by or on behalf of the Issuers, the Purchasers or any person controlling any of them and will survive the execution and delivery of the Notes and Series A Shares to the Purchasers and payment by the Purchasers therefor. All such covenants, agreements, representations and warranties shall be binding upon any successors and assigns of the Issuers. In 14 addition, whether or not any express assignment has been made except as otherwise provided in Article 7 hereof, all holders of the Notes and Series A Shares who hold such Notes or Series A Shares as transferees from the Purchasers hereunder shall be entitled to the benefit of all covenants and agreements of the Issuers made or to be performed or observed by the Issuers (but not the representations and warranties made by the Issuers herein or in any document or agreement which is incorporated by reference herein). 13. COMMUNICATIONS AND NOTICES. Except as otherwise provided in this Agreement, all communications and notices provided for in this Agreement shall be in writing and (i) if to any of the Issuers mailed by first class mail or overnight courier to them at EnviroSystems Corp. c/o Environmental Systems Products Holdings Inc., 7 Kripes Road, East Granby, Connecticut 06026, Attention: David J. Langevin or any other office that such Issuer may hereafter designate by written notice to the Purchasers and (ii) if to the Purchasers, mailed by first class mail or overnight courier to the respective addresses of the Purchasers specified in the signature pages hereto, or to such other address and for such attention as any Purchaser may from time to time designate to the Parent or the Company in writing. 14. LAW GOVERNING. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, without regard to the principles of conflicts of laws thereof. 15. SEVERABILITY. In case any one or more of the provisions contained in this Agreement or in any instrument contemplated hereby, or any application thereof, shall be invalid, illegal or unenforceable in any respect, under the laws of any jurisdiction, the validity, legality and enforceability of the remaining provisions contained herein and therein, and any other application thereof, shall not in any way be affected or impaired thereby or under the laws of any other jurisdiction. 16. HEADINGS. The headings of the articles, sections and subsections of this Agreement are inserted for convenience only and shall not be deemed to constitute a part of this Agreement. 15 If the foregoing is in accordance with your understanding, please sign and complete the enclosed copy of this letter on the signature page provided and return it to the Parent and the Company, whereupon this letter shall then become a binding agreement in accordance with its terms.
