the existing Section 3.1 in its entirety and replacing it with the following
text:

          "3.1 GOAL OF TECHNOLOGY ALLIANCE PROGRAM. The goal of the Technology
     Alliance Program is to (i) produce PHA Cell Paste, in a fermenter having a
     capacity of approximately *, and at ADM Sub's option then in a fermenter
     having a capacity of approximately *, in all cases, in a manner and with
     results that meet the applicable Fermentation Performance Parameters; (ii)
     demonstrate recovery of PHA Material in a manner and with results that meet
     the Recovery Performance Parameters (the items listed in the foregoing
     "(i)" and "(ii)" collectively are the "Technical Aspects of the Goal"); and
     (iii) based upon the results of (i) and (ii) above, have ADM Sub develop
     and the TAC agree upon a completed master plan for Construction of the ADM
     Sub Manufacturing Facility, including without limitation, surveys,
     blueprints, and engineering studies, which master plan shall be organized
     into a detailed, multiphase process for undertaking and completing
     Construction of the ADM Sub Manufacturing Facility and which shall have a
     project budget with projected detailed expenditures provided for each phase
     of the Construction process, all of which shall be, in form and substance,
     suitable for ADM Sub's management and board of directors to make a
     determination to approve the expenditures for the ADM Sub Manufacturing
     Facility as and to the extent required by ADM Sub's corporate governance
     polices and procedures (the "ADM Sub Construction Master Plan and Budget")
     (collectively the "Goal"). Successful completion of the Goal is intended to
     confirm the potential economics of producing PHA Material at commercial
     scale as part of a long-term commercial alliance."

     2.3 ADDITION OF SECTION 3.2.4.1. The Agreement is hereby amended by adding
the following Section 3.2.4.1:

          "3.2.4.1 INITIAL RECOVERY OPERATIONS. The Parties hereby agree that
     MBX will enter into an agreement to obtain access to toll recovery
     services, from a Third Party (the "Toll Producer") on substantially the
     terms set forth in the tolling agreement attached hereto as Schedule A (the
     "Tolling Agreement"). These recovery services are anticipated to last until
     approximately March of 2006 and to result in the recovery of up to
     approximately thirty five (35) metric tons of PHA Material (the "Initial
     Recovery Services"). Except as specifically set forth herein, the Parties'
     rights and obligations with respect to the Initial Recovery Services and
     the PHA Material produced in connection therewith shall be governed by the
     Agreement as activities conducted under Section 3.2.4. Responsibility for
     the fees charged by the Toll Producer under the Tolling Agreement for the
     Initial Recovery Services, related equipment and capital expenses, and the
     reasonable out-of-pocket expenses of the Parties in performing technical
     support or auditing of the Initial Recovery Services, including, for
     example, travel and lodging expenses, but excluding, salary and benefits
     paid or payable to employees or representatives of the Parties
     participating in such activities (collectively, "Tolling Expenses") shall
     be shared equally by the Parties, subject to the limitations set forth
     herein. The Parties shall, determine reasonable

                                        2

<Page>

     methods for promptly accounting for the total Tolling Expenses on a monthly
     basis and making such payments as are necessary in order to give effect to
     the equal sharing of the Tolling Expenses. Notwithstanding the foregoing:
     (i) MBX shall be solely responsible for the operating expenses (including
     its internal costs and the costs of the Toll Producer but excluding the
     related equipment and capital expenses) until (y) the earlier of TAC's
     determination that the recovery of PHA Material during a Recovery Campaign
     was achieved in a manner and with results that met the Recovery Performance
     Parameters as defined in Amended Exhibit E on any one of the three
     specified compositions, or ADM Sub's payment of the milestone payment set
     forth in Section 5.1 related to the Recovery Performance Parameters, and
     (z) ADM's receipt of a letter from the U.S. Drug Enforcement Administration
     advising that polyhydroxyalkanoate containing gamma-hydroybutyric acid as
     part of the polymer chain will not be regulated as a controlled substance
     under the Controlled Substances Act and any Drug Enforcement Administration
     regulations, (ii) ADM shall not be obligated to pay in excess of * of
     Tolling Expenses hereunder; (iii) ADM shall not be obligated to pay in
     excess of * of the equipment and capital expenses comprising the Tolling
     Expenses hereunder; and (iv) ADM shall not be responsible for any Tolling
     Expenses incurred after the end of the term of this Agreement as set forth
     in Section 8.1, except as otherwise provided under the Commercial Alliance
     Agreements, if applicable. In the event ADM terminates this Agreement or
     decides not to exercise the Option, then MBX shall pay ADM an amount equal
     to one half of the depreciated book value of any removable assets (i.e.,
     not fixtures) that are listed on the Consignment Agreement or any Addendum
     to Consignment Agreement (as such agreement and such addendum are
     referenced in the Tolling Agreement), the purchase price for which was
     funded equally by the Parties. MBX agrees to provide ADM with equal access
     to the facility of the Toll Producer as and to the extent such access is
     made available to MBX and its designees under the Tolling Agreement. The
     PHA Material produced in connection with the Initial Recovery Services
     shall be part of the Technology Alliance Output or Marketing Material as
     determined under Section 3.3, and, in the event it is sold by MBX, all
     revenues generated by such sales shall be applied against Tolling Expenses
     before such expenses are allocated for payment by the Parties. The Parties
     agree to work together to determine the costs (capital expenditures and
     operating costs) to use ADM's Vitamin C facility for pilot sourcing of PHA
     Material in the event ADM exercises the Option; provided, however, nothing
     herein shall preclude ADM from utilizing all or any portion of the Vitamin
     C facility for other uses."

     2.4 AMENDMENT OF SECTION 3.3. The Agreement is hereby amended by deleting
the existing Section 3.3 in its entirety and replacing it with the following
