        pending of Planet which has not been held to be either invalid or
        unenforceable by a final decision from which no appeal is or can be
        taken.

2.b)    The Sales Royalty amount due Planet under sub-paragraph 2.a) above shall
        be calculated as follows; apply the following percentages based on Net
        Sales and Revenues for each of Agway's Full Fiscal Years during the term
        of this Sub-Agreement except that the calculation of Net Sales and
        Revenues shall commence with the start of the first quarter in which the
        Optigen Project has a profitable quarter:

               [*};
               [**]; and,
               [***].

2.c)    Notwithstanding the calculation of a Sales Royalty under subparagraph
        2.b) above, whether any payment is due Planet under subparagraph 2.b)
        above and the amount of any such payment shall be subject to the
        following three rules.

        Rule No. 1. Determine whether the Optigen Project was profitable for the
        fiscal quarter being measured; if the Optigen Project was profitable for
        said quarter, the Sales Royalty payment due Planet shall be calculated
        as set forth under subparagraph 2.b) above; however, if the Optigen
        Project was not profitable for said quarter, no Sales Royalty shall be
        due Planet for said quarter;

        Rule No. 2. The quarterly Sales Royalty payment to Planet shall not
        exceed [*] of the quarterly Pre-Tax Earnings/(Loss) Before Sales
        Royalty; if the quarterly Sales Royalty payment otherwise due Planet
        exceeds [**] of the quarterly Pre-Tax Earnings/(Loss) Before Sales
        Royalty, then, the quarterly Sales Royalty payment due Planet shall be
        reduced to an amount equal to [***] of the quarterly Pre-Tax
        Earnings/(Loss) before Sales Royalty; and,

        Rule No. 3. Determine whether the Optigen Project To Date Losses have
        been reduced to [*]; if said losses have been reduced to [**], the
        quarterly Sales Royalty payment due Planet shall be paid to Planet;
        however, if the Optigen Project To Date Losses have not been reduced to
        [***], then, the quarterly Sales Royalty payment due Planet as
        calculated under subparagraph 2.b) and modified as specified under
        subparagraph 2.c) Rule No. 1 and Rule No. 2 shall be reduced by [****].
        If the reduction in payment from the application of this Rule No. 3
        exceeds the remaining Optigen Project To Date Losses, the percentage
        reduction shall be reduced to such lower percentage as necessary to
        bring the Optigen Project To Date Losses to [*****].

2.d)    It is the intent of the parties that the following principles apply:

        (i)     No quarterly Sales Royalty under subparagraph 2.b) above will
                become due or payable unless and until CPG Nutrients or any of
                its successors has [*].

        THE PORTIONS OF THIS DOCUMENT OMITTED AND MARKED WITH
        ASTERISKS AND BRACKETS IS SUBJECT TO A CONFIDENTIAL
        TREATMENT REQUEST FILED SEPARATELY WITH THE SEC

        (ii)    The quarterly Sales Royalty due and payable to Planet under
                subparagraph 2.b) above shall not exceed CPG Nutrients or any of
                its successors quarterly Pre-Tax Earnings Before Sales Royalty
                on the Product; if CPG Nutrients or any of its successors
                quarterly Pre-Tax Earnings Before Sales Royalty on the Product
                is less than [*] the quarterly Sales Royalty due Planet, the
                quarterly Sales Royalty payable to Planet will be reduced to be
                equal to [**] of CPG Nutrients or any of its successors
                quarterly Pre-Tax Earnings Before Sales Royalty; and,

        (iii)   Until and unless CPG Nutrients or any of its successors has
                recouped the Optigen Project To Date Losses, the quarterly Sales
                Royalty payable, as calculated under subparagraph 2.b) above, to
                Planet will be [*] the Sales Royalty amount otherwise determined
                under this Sub-Agreement.

2.e)    The Sales Royalty payment as calculated above becomes due at the end of
        each fiscal quarter, and payable within 45 days thereafter. With each
        such payment, CPG Nutrients or any of its successors shall furnish
        Planet a report in sufficient detail to permit confirmation of the
        accuracy of the Sales Royalty payment made, including without
        limitation, the sales of the Product during the fiscal quarter being
        reported, the Sales Royalty payment in United States dollars, the method
        used to calculate the Sales Royalty payment and the exchange rate used.

2.f)    At the end of each Full Fiscal Year, an annual Sales Royalty true-up
        will be calculated. The Sales Royalty annual true-up will apply the
        calculation provisions of paragraphs 2.b) and 2.c) to the Net Sales and
        Revenues for the Full Fiscal Year to determine the actual amount due
        Planet for the Full Fiscal Year. This amount will be compared to the
        amounts calculated as due Planet under the four quarterly calculations
        for that corresponding Full Fiscal Year. If the annual calculation
        indicates a higher amount due Planet, that payment is due 90 days after
        the end of the Full Fiscal Year. If the annual calculation indicates a
        lower amount is due Planet, the difference will be deducted from the
        next succeeding payment(s) due Planet. CPG Nutrients or any of its
        successors shall furnish Planet a report in sufficient detail to permit
        confirmation of the accuracy of the Sales Royalty true-up, including
        without limitation, the sales of the Product during the fiscal year
        being reported, the Sales Royalty payment in United States dollars, the
        method used to calculate the Sales Royalty payment and the exchange rate
        used.

3.      Minimum Annual Royalty. The sole purpose of the Minimum Annual Royalty
        is to compensate Planet for granting exclusive license rights to Agway
        for the Product under this Sub-Agreement.

3.a)    If the annual Sales Royalty amount, solely as calculated in subparagraph
        2.b) above, is less than the Minimum Annual Royalty, as identified in
        subparagraph 3.b) below, for the corresponding Full Fiscal Year, then,
        payment of this incremental difference is due to Planet resulting in
        full satisfaction of the Minimum Annual Royalty.

        If the annual Sales Royalty amount, solely as calculated in subparagraph
        2.b) above, is greater than the Minimum Annual Royalty, as identified in
        subparagraph 3.b) below, for the

        corresponding Full Fiscal Year, then, the intent of the Minimum Annual
        Royalty has been fully satisfied. Therefore, the Minimum Annual Royalty
        provision is not applicable for the corresponding Full Fiscal Year.

               Fiscal Year Three                          [***]

               Fiscal Year Seven                          [*******]
               Fiscal Year Eight                          [********]
        Each Subsequent Fiscal Year Thereafter            [*********]
</TABLE>

        Fiscal Year One shall commence on the first day of the Full Fiscal Year
        immediately following receipt of an Association of America Feed Control
        Officials, Inc. (AAFCO") feed ingredient definition for [* * * * *]. If
        the AAFCO feed ingredient definition is received within the first 60
        calendar days of a Full Fiscal Year, then, the AAFCO receipt shall be
        deemed to have been received in the prior Full Fiscal Year, and Fiscal
        Year One shall commence as of the first day of the Full Fiscal Year in
        which the AAFCO receipt was received.

3.c)    In order to maintain exclusive license rights to Product, the Minimum
        Annual Royalty amount due as determined in subparagraph 3.a) will be
        made by October 31 immediately following the Full Fiscal Year of
        measurement. Agway may choose to not pay the Minimum Annual Royalty for
        any and all Full Fiscal Years, and Planet shall have no rights or
        recourse against Agway for such payment for that year or for any future
        Full Fiscal Years. However, if Agway fails to make a timely Minimum
        Annual Royalty payment, Planet reserves the right to provide Agway with
        a written notice of such failure to pay, and Agway will have 60 days
        from receipt of such notice to remedy such shortfall in payment. If
        Agway does not cure its failure to make the Minimum Annual Royalty
        payment within the 60-day cure period, then, Planet's only recourse and
        remedy will be to grant non-exclusive license rights to Product to other
        parties. Despite Agway's failure to make Minimum Annual Royalty
        payments, this Sub-Agreement shall continue in full force and effect but
        on a non-exclusive basis, and no Minimum Annual Royalty shall be due
        from Agway.

4.      In the event that any Sales Royalty payments due hereunder are not made
        when due, the payments shall accrue interest from the due date at the
        prime lending rate as of said date as published in The Wall Street
        Journal; provided, however, that in no event shall such rate exceed the
        maximum legal annual interest rate. The payment of such interest shall
        not limit Planet from exercising any other rights it may have as a
        consequence of the lateness of any payment.

5.      All payments owed under this Sub-Agreement shall be made by wire
        transfer to a bank account designated by Planet, unless otherwise
        specified in writing by Planet. All payments due Planet under this
        Sub-Agreement shall be paid in United States dollars, free of taxes
        payable in any foreign country, except for such taxes as result in, and
        to the extent that the same do result in a foreign tax credit applicable
        to the United States taxes payable by Planet. With respect to each
        quarter, for countries other than the United States, whenever conversion
        of payments from any foreign currency shall be required, such conversion
        shall be made at the rate of exchange required of CPG Nutrients or any
        of its successors under generally accepted accounting principles for the
        applicable accounting period.

6.      Agway and its affiliates shall keep accurate books and records as
        reasonably needed for determination of Sales Royalty payments due under
        paragraph 2 above. Such books and records shall be maintained for a
        period of at least three years from the expiration of the relevant Sales
        Royalty payment period.

7.      Not more than once in each fiscal year, Planet may have the books and
        records of CPG Nutrients, or any of its successors, audited by an
        independent certified public accounting firm (CPA Firm) reasonably
        acceptable to Agway to the extent necessary to verify the correctness of
        any Sales Royalty payment report furnished under this Sub-Agreement. If
        such independent CPA Firm should determine that an underpayment of Sales
        Royalty may have occurred, Agway may have Agway's independent
        accountants review the CPG Nutrients records and the report and
        calculations of the CPA Firm to determine Agway's independent
        accountants' assessment of the amount due under this Sub-Agreement. If
        the CPA Firm and Agway's independent accountants do not agree and the
        parties cannot agree to a mutually satisfactory resolution, then, a
        third mutually agreeable nationally recognized independent certified
        public accounting firm shall be hired by the parties to finally resolve
        the correct amount due. The determination by the third independent
        certified public accounting firm shall be final. The CPA Firm and any
        third firm shall keep all information received in connection with any
        audit confidential, and they shall report to Planet and Agway only the
        accuracy of and/or any deficiencies in any such Sales Royalty payment
        report. The fee for such CPA Firm and any third firm shall be paid by
        Planet, unless the audit finally results in an upward adjustment of
        Sales Royalty payments due Planet by more than 5% of the amount due
        under this Sub-Agreement; in such case, Agway shall pay the full cost of
        such audits. In any event, Agway shall pay any finally determined
        underpayment with interest in accordance with paragraph 4 above.

8.      The Sub-Agreement effective as of September 22, 1999 is hereby
        terminated and is replaced with this Sub-Agreement as of the Effective
        Date of this Sub-Agreement, and this Sub-Agreement shall be a part of
        the License Agreement entered into between Agway and Planet effective
        the 12th day of November, 1998 and incorporates all the terms thereof to
        the extent they are not inconsistent herewith. In the event of any
        inconsistency between the terms of the License Agreement and this
        Sub-Agreement, this Sub-Agreement shall govern the rights, duties,
        privileges and obligations of the parties.
