assuring that such payments are made in satisfaction of such obligations the
Company has established a trust in the form of this rabbi trust (commonly
referred to as "Rabbi Trust B") which is subject to the claims of the Company's
existing or future general creditors; and

            WHEREAS, the Company's fiscal year has changed to the calendar year;
and

            WHEREAS, the Company has changed its name to Sensient Technologies
Corporation, subject to shareholder approval at the annual meeting of
shareholders scheduled to be held in April 2001; and

            WHEREAS, the Company wishes to amend the trust agreement for Rabbi

            from such date) pay to the Trustee: (i) an amount in cash,
            marketable securities (valued at their fair market value) or life
            insurance policies or any combination thereof equal to such excess;
            less (ii) the amount, if any, of interest and other income earned on

                        "(b) Except as hereinafter provided, all interest and
            other income earned on the investment of the Trust Corpus, except
            dividends on and proceeds from life insurance policies, shall be the
            property of the Company and shall not constitute a part of the Trust
            Corpus. Within twenty (20) days after the end of each year ending
            December 31, the Trustee shall notify the Company of the amount of
            such interest and other income received by the Trustee during such
            year then ended. Such interest and other income received by the
            Trustee during each year then ending December 31 shall be paid over
            to the Company by the Trustee within thirty (30) days after the end
            of each such year. The amount of such interest or other income so
            payable to the Company shall be reduced to the extent that it
            offsets the excess otherwise required to be paid by the Company to
            the Trustee pursuant to Section 2.01(c) hereof, and only the
            remainder, if any, shall be paid to the Company."

            4. The first sentence of paragraph (c) of Section 4.01 is hereby

            be necessary for the proper administration of the Trust Corpus,
            including, without limitation, as provided in Section 2.01 hereof,
            and shall render to the Company on or prior to each January 31,
            beginning January 31, 2002, until the termination of this Trust, an

            immediately preceding December 31 (and as of the date of the Trust's
            termination)."

            5. Section 6.04 is amended by replacing the reference to "Universal
Foods Corporation" with "Sensient Technologies Corporation".
