The Company hereby grants to Purchaser an irrevocable option (the "Option") to purchase on each Exercise Closing Date, on the terms and subject to the conditions set forth herein, up to the number of newly-issued shares of Common Stock (the "Shares") equal, as of the related Exercise Date, to the number of shares of Common Stock that Ciba would be permitted to purchase from Persons other than the Company as of such Exercise Date under the Governance Agreement. SECTION 2.02. EXERCISE OF OPTION. (a) The Option may be exercised by Purchaser (or its designee, which designee must be Ciba or a direct or indirect wholly owned Subsidiary of Ciba), in whole or in part, at any time, or from time to time (the date of any such exercise being referred to as an "Exercise Date"), during the period beginning upon the Closing and ending on the termination of the Standstill Periods, so long as an Exercise Condition shall exist on such Exercise Date; PROVIDED, HOWEVER, that Purchaser may not exercise the Option at any time unless it owns Equity Securities (assuming full conversion or execute thereof) representing at least 30% of the Total Voting Power.

(b) In order for Purchaser to exercise the Option, Purchaser shall give written notice to the Company of such exercise, specifying the number of Shares to be purchased (and the denominations of the share certificate or certificates to be issued), whether Purchaser and/or a designee of Purchaser (which must be Ciba or a wholly owned Subsidiary of Ciba) will be purchasing the Shares and the place, time and date of the closing of such purchase (the "Exercise Closing Date" or the "Exercise Closing"), which date shall not be less than two business days nor more than ten business days from the date on which such notice is delivered. 6 (c) At each Exercise Closing, the Company shall deliver to Purchaser (or its designee) all of the Shares to be purchased by delivery of a certificate or certificates evidencing such Shares in the denominations designated by Purchaser in the notice required under Section 1.02(b).

SECTION 2.03. PURCHASE PRICE; PAYMENT. The purchase price for any Shares purchased pursuant to an exercise of the Option shall be the Fair Market Value of such Shares, determined as of the business day three business days prior to the relevant Exercise Closing.

SECTION 2.04. NOTICE OF OUTSTANDING STOCK. Until the termination of the Standstill Periods, the Company shall, within 7 days after the end of each month commencing with December 1994, deliver written notice to Ciba and Purchaser of the number of Shares and the number of shares of other Voting Stock outstanding as of the last day of such month.
