Novotny & Associates, Inc. (212) 490-2065/2977 INTERNATIONAL SPECIALTY PRODUCTS SENDS LETTER --------------------------------------------- TO BOARD OF DIRECTORS OF DEXTER CORPORATION ------------------------------------------- WAYNE, NJ - International Specialty Products Inc. (NYSE - "ISP") has sent the following letter to the Board of Directors of Dexter Corporation (NYSE - "DEX"): June 6, 2000 Board of Directors Dexter Corporation Dear Board Member, As you know, we strongly believe that the piecemeal sale of Dexter's businesses would be a big mistake, will only diminish shareholder values further rather than maximize them, and constitutes, in our opinion, little more than scorched earth tactics on the part of the Company. Moreover, it is further our view that any sale of substantial Dexter assets prior to the upcoming Annual Meeting would make a mockery of the electoral process and deprive shareholders of their right to determine fundamental issues concerning Dexter's future - which is, of course, in good measure what the proxy contest is all about. Notwithstanding, Dexter has indicated, in its May 17th letter, that it is "proceeding expeditiously" to develop interests in, and may enter into "unconditional, binding agreements to sell," Dexter's wholly owned businesses, and has refused to commit to condition such sale on the receipt of NY2:\919278\01\54104.0016 shareholder approval. As we have previously stated, we believe that the piecemeal sale of Dexter's businesses makes no sense whatsoever and the sale of the Company in its entirety, which Dexter claims it is pursuing as another option, is the best way to maximize value for Dexter shareholders. In this connection, in case you have not already been informed by Dexter's counsel, I would call your attention to the colloquy during the parties' telephone conference last week with the Connecticut federal court concerning this issue. At that conference, there was extensive discussion of the potential harm to Dexter should it enter into unconditional, definitive, binding agreements for the sale of one or more of its business units that are either not subject to shareholder approval or do not enable the Company to terminate the agreement without making a payment in the event that the court were to hold that the transaction is subject to shareholder approval. As ISP's counsel explained to the court, and your lawyer apparently did not refute, the absence of such provision will potentially expose Dexter to substantial liability in connection with a claim for breach of contract by a purchaser in the event that the court ultimately determines that shareholder approval was required. In light of this discussion, ISP trusts that Dexter's directors, should they decide to pursue the piecemeal sale option, which we repeat is in our view a big mistake and could subject you to substantial liability, will at least take all steps necessary to ensure that any sales agreement entered into by the Company contain explicit language regarding shareholder approval sufficient to insulate Dexter from any breach of contract claim by a third party purchaser. Please be advised that ISP intends to hold Dexter's directors accountable for money damages for any injury to Dexter which shall result from the Board's failure to include provisions referred to above in any agreement providing for the sale of one or more of Dexter's businesses. Finally, in accordance with the federal court's expressed willingness to entertain our motion should there be a transaction to be brought to the court's attention, should you fail to condition such sales on shareholder approval, we intend to move for a preliminary injunction. Sincerely, /s/ Samuel J. Heyman Chairman International Specialty Products Inc. 2 * * * * International Specialty Products Inc. is a leading multinational manufacturer of specialty chemicals and mineral products.
