favor of the Merger or consented thereto in writing and who shall have demanded
properly in writing appraisal for such Shares in accordance with Section 262 of

Current Transaction Summary

Transaction Date
- ----------------

   1/28/97               Van Gogh was notified that Matisse was planning to
                         publicly announce an offer to acquire the remaining 45%
                         of Van Gogh for $7.25 per share. The Independent
                         Directors immediately hired Montgomery Securities and
                         Venture Law Group as financial and legal advisors,
                         respectively.

   1/29/97               Matisse publicly announced an offer of $7.25 per share.
                         The Independent Directors announced that a Special
                         Committee had been formed to consider this initial
                         offer.

2/2/97-3/5/97            The Special Committee, Montgomery, and Venture Law
                         Group held multiple discussions and meetings as part of
                         negotiations with Matisse and its financial advisor,
                         Goldman, Sachs & Co.

   3/6/97                The Special Committee decided to recommend Matisse's
                         offer to acquire the remaining shares of Van Gogh it
                         does not already own for $8.00 per share (subject to
                         agreement of certain contractual terms). Closing of the
                         transaction is contingent on a majority of the minority
                         shares being tendered.

Executive Summary
================================================================================
Rationale for the Transaction

    o Realize Substantial Value for Van Gogh Shareholders

        At the $8.00 offer price, Van Gogh shareholders (other than Matisse)
        recognize a 45%, 60%, and 60% premium over the stock price one day, one
        week and one month preceding this offer, respectively. These premiums
        fall at the high end of the ranges or above the ranges as determined by
        substantially all of Montgomery's analyses.

    o Standstill Clause in Effect until 9/30/98

        As a result of the 3/96 transaction between Matisse and Van Gogh, a
        standstill clause is in place which requires that the Independent
        Directors of Van Gogh approve any additional acquisition of Van Gogh
        shares by Matisse. This clause is in effect until 9/30/98. As such, the
        Special Committee offers some degree of protection to minority
        shareholders if a transaction occurs before 9/30/98. Monsanto's interest
        in acquiring the remaining shares of Calgene is to simplify its
        ownership in Calgene to operate the business unencumbered by the
        constraints of the standstill clause

    o Secure Future Financial Resources for Van Gogh

        Since inception, Van Gogh has been unable to sustain profitability for
        any significant period of time and has accumulated losses of
        approximately $200 million. Van Gogh anticipates that it will require
        additional financing in order to continue its operations. At this point
        in time, the equity and debt markets are not a viable option for Van
        Gogh. As such, the significant financial resources of Matisse provide an
        avenue by which Van Gogh can secure the capital necessary to maintain
        solvency.

Executive Summary
================================================================================
Rationale for the Transaction

    o Matisse's Recent Focus on Biotechnology

        A recent Forbes article [Matisse] v. Malthus, dated March 10, 1997,
        discusses Matisse's recent focus on biotechnology with respect to food
        and nutrition. In support of this argument, the authors cite that
        Matisse has made significant equity investments totaling over $750
        million in a number of agricultural biotechnology companies including
        DeKalb Genetics (40%), Ecogen (10%), Agracetus (100%), and Calgene
        (55%). These recent actions support the conclusion that Matisse's
        business platform is central to Matisse's business strategy.

    o Matisse's Proprietary Property in Biotechnology

        As a leader in agriculture and bioengineering, and as a result of the
        recent equity investments mentioned above, Matisse has access to, and in
        many cases, ownership of, proprietary property which may be leveraged in
        the future development of products by Van Gogh.
