Registration Rights. In the event that the Grantee shall desire to sell any of the shares of the Grantor Common Stock purchased pursuant to the Stock Option within two (2) years after such purchase, and such sale requires in the opinion of counsel to the Grantor, which opinion shall be reasonably satisfactory to the Grantee and its counsel, registration of such shares under the Securities Act of 1933, the Grantee may, by written notice (the "Registration Notice") to the Grantor (the "Registrant"), request the Registrant to register under the Securities Act all or any part of the shares purchased pursuant to the Stock Option ("Restricted Shares") beneficially owned by the Grantee (the "Registrable Securities") pursuant to a bona fide firm commitment underwritten public offering in which the Grantee and the underwriters shall effect as wide a distribution of such Registrable Securities as is reasonably practicable and shall use their best efforts to prevent any person (including any Group) and its affiliates from purchasing through such offering Restricted Shares representing more than 2% of the outstanding shares of common stock of the Registrant on a fully diluted basis (a "Permitted Offering"). The Registration Notice shall include a certificate executed by the Grantee and its proposed managing underwriter, which underwriter shall be an investment banking firm of nationally recognized standing reasonably acceptable to the Grantor (the "Manager"), stating that (a) it has a good faith intention to commence promptly a Permitted Offering and (b) the Manager in good faith believes that, based on the then prevailing market conditions, it will be able to sell the Registrable Securities at a per share price to be specified in such Registration Notice (the "Fair Market Value"). The Registrant (and/or any person designated by the Registrant) shall thereupon have the option, exercisable by written notice delivered to the Grantee within ten (10) business days after the receipt of the Registration Notice, irrevocably to agree to purchase all or any part of the Registrable Securities for cash at a price (the "Option Price") equal to the product of (a) the number of Registrable Securities and (b) the Fair Market Value of such Registrable Securities. Any such purchase of Registrable Securities by the Registrant hereunder shall take place at a closing to be held at the principal executive offices of the Registrant or its counsel at any reasonable date and time designated by the Registrant and its designee in such notice within twenty (20) business days after delivery of such notice. Any payment for the shares to be purchased shall be made by delivery at the time of such closing of the Option Price in immediately available funds. If the Registrant does not elect to exercise its option pursuant to this Section 7 with respect to all Registrable Securities designated in the Registration Notice, it shall use its best efforts to effect, as promptly as practicable, the registration under the Securities Act of the unpurchased Registrable Securities; provided, however, that (a) the Grantee shall not be entitled to more than an aggregate of two effective registration statements hereunder and (b) the Registrant will not be required to file any such registration statement during any period of time (not to exceed 90 days after such request in the case of clause (ii) below or 120 days in the case of clauses (i) and (iii) below) when (i) the Registrant is in possession of material non-public information which it reasonably believes would be detrimental to be disclosed at such time and, in the judgment of the Board of Directors of the Registrant, such information would have to be disclosed if a registration statement were filed at that time; (ii) the Registrant is required under the Securities Act to include audited financial statements for any period in such registration statement and such financial statements are not yet available for inclusion in such registration statement; or (iii) the Registrant determines, in its reasonable judgment, that such registration would interfere with any financing, acquisition or other material transaction involving the Registrant or any of its affiliates. If consummation of the sale of any Registrable Securities pursuant to a registration hereunder does not occur within 120 days after the filing with the SEC of the initial registration statement with respect thereto, the provisions of this Section 7 shall again be applicable to any proposed registration; provided, however, that the Grantee shall not be entitled to request more than two registrations pursuant to this Section 7 to be qualified for sale under the securities or blue-sky laws of such jurisdictions as the Grantee may reasonably request and shall continue such registration or qualification in effect in such jurisdiction; provided, further, that the Registrant shall not be required to qualify to do business in, or consent to general service of process in, any jurisdiction by reason of this provision. The registration rights set forth in this Section 7 are subject to the condition that the Grantee shall provide the Registrant with such information with respect to the Grantee's Registrable Securities, the plans for the distribution thereof, and such other information with respect to the Grantee as, in the reasonable judgment of counsel for the Registrant, is necessary to enable the Registrant to include in such registration statement all material facts required to be disclosed with respect to a registration thereunder. A registration effected under this Section 7 shall be effected at the Registrant's expense, except for underwriting discounts and commissions and the fees and the expenses of counsel to the Grantee, and the Registrant shall provide to the underwriters such documentation (including certificates, opinions of counsel and "comfort" letters from auditors) as are customary in connection with underwritten public offerings as such underwriters may reasonably require. In connection with any such registration, the parties agree (a) to indemnify each other and the underwriters in the customary manner and (b) to enter into an underwriting agreement in form and substance customary to transactions of this type with the Manager and the other underwriters participating in such offering. 8. Adjustment upon Changes in Capitalization. In the event of any change in the Grantor Common Stock by reason of stock dividends, stock splits, mergers (other than the Merger), recapitalizations, combinations, exchange of shares or the like, the type and number of shares or securities subject to the Stock Option, and the Exercise Price per share, shall be adjusted appropriately. 9. Restrictive Legends. Each certificate representing shares of the Grantor Common Stock issued to the Grantee hereunder shall initially be endorsed with a legend in substantially the following form: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION AND APPLICABLE STATE SECURITIES LAWS IS AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE TERMINATION OPTION AGREEMENT, DATED MAY 8, 1998, A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER HEREOF. 10. Binding Effect; No Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, and permitted assigns. Except as expressly provided in this Agreement, neither this Agreement nor the rights or the obligations of either party hereto are assignable, except by operation of law, or with the written consent of the other party. Nothing contained in this Agreement, express or implied, is intended to confer upon any person other than the parties hereto and their respective permitted assigns any rights or remedies of any nature whatsoever by reason of this Agreement. Any Restricted Shares sold by a party in compliance with the provisions of Section 7 hereof shall, upon consummation of such sale, be free of the restrictions imposed with respect to such shares by this Agreement, in no event will any transferee of any Restricted Shares be entitled to the rights of the Grantee hereunder. Certificates representing shares sold in a registered public offering pursuant to Section 7 hereof shall not be required to bear the legend set forth in Section 9 hereof. 11. Incorporation by Reference. The provisions of Sections 7.01, 10.01, 10.04, 10.06, 10.07, 10.08 and 10.09 of the Merger Agreement are incorporated herein by reference, to be read as though the references therein to the Merger Agreement were references to this Agreement. * * * * * I:\VISITOR\MONSANTO\TERMOPT.007 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
