If for any reason the Company is not eligible to file a

-3-

Demand Registration on Form S-3 or any similar short-form registration statement, then the Company shall effect such Demand Registration using such form as the Company is then eligible to use. The request for a Demand Registration shall specify the approximate number of Registrable Securities requested to be registered and the intended method of distribution. Within ten days after receipt of such request, the Company shall give written notice of such requested registration to all other holders of Registrable Securities and, subject to Section 3.3, shall include as part of such Demand Registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of the Company’s notice by such holders.

3.2 Limitations on Demand Registration. The holders of the Registrable Securities shall be entitled to request one (1) Demand Registration with respect to Registrable Securities; provided, that, the aggregate offering price of Registrable Securities requested to be registered in such Demand Registration must be equal to at least $10 million. The holders of a majority of the Registrable Securities which are included in a Demand Registration may require the Company to file such Demand Registration with the Commission in accordance with and pursuant to Rule 415 promulgated under the Securities Act (or any successor rule then in effect) (a “Shelf Registration”).

3.3 Priority on Demand Registration. If a Demand Registration is an underwritten offering and the managing underwriters advise the Company in writing, with a copy to be delivered to all the holders of Registrable Securities, that, in their opinion, the number of Registrable Securities requested to be included in such offering exceeds the number of securities which can be sold therein without materially adversely affecting the marketability of the offering and within a price range acceptable to the holders of a majority of the Registrable Securities requesting registration, the Company shall first include in such registration, prior to the inclusion of any securities which are not Registrable Securities, the Registrable Securities requested to be included which in the opinion of such underwriters can be sold without materially adversely affecting the marketability of the offering, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such requesting holder.

3.4 Restrictions on Registration. The Company shall not be obligated to effect a Demand Registration within 270 days after the effective date of a registration of Common Stock in which the holders of Registrable Securities were given piggyback rights pursuant to Section 4 and in which there was no reduction in the number of Registrable Securities requested to be included. The Company may postpone for up to 90 days the filing or the effectiveness of a registration statement for a Demand Registration if the Company furnishes to the Qualified Holders a certificate signed by the Chief Financial Officer of the Company stating that such Demand Registration would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any of its subsidiaries to engage in any financing, acquisition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer, reorganization or other significant transaction; provided, that, in such event, the holders of Registrable Securities initially requesting such Demand Registration shall be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as the permitted Demand Registration hereunder; and provided, further, that the Company may not exercise this deferral right more than once in any 12-month period.

-4-

3.5 Selection of Underwriters. The Company shall have the right to select the investment banker(s) and manager(s) to administer the offering in connection with a Demand Registration, subject to the approval of the holders of a majority of the Registrable Securities included in such Demand Registration (which approval shall not be unreasonably withheld or delayed).

4. Piggyback Registrations.

4.1 Right to Piggyback. At any time beginning 30 days prior to the 18-month anniversary of the Closing Date, whenever the Company proposes to register any of its securities under the Securities Act (other than pursuant to a Demand Registration which shall be governed by Section 3, and registrations related solely to employee benefit plans or a Rule 145 transaction) and both (i) the registration form to be used may be used for the registration of Registrable Securities, and (ii) the registration is reasonably expected to become effective after the 18-month anniversary of the Closing Date (a “Piggyback Registration”), the Company shall give prompt written notice to all holders of Registrable Securities of its intention to effect such a registration and, subject to the terms hereof, shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 21 days after such holders receive the Company’s notice.

4.2 Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold therein without adversely affecting the marketability of the offering, the Company shall include in such registration (a) first, the securities the Company proposes to sell, (b) second, any securities Cargill proposes to sell pursuant to the Cargill Registration Rights Agreement, (c) third, the Registrable Securities requested to be included in such registration, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder and (d) fourth, other securities requested to be included in such registration.

4.3 Priority on Other Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities other than holders of Registrable Securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company shall include in such registration (a) first, the securities requested to be included therein by the holders requesting such registration, (b) second, any securities Cargill proposes to sell pursuant to the Cargill Registration Rights Agreement, (c) third, the Registrable Securities requested to be included in such registration, pro rata among the holders of such securities on the basis of the number of Registrable Securities owned by each such holder and (d) fourth, other securities requested to be included in such registration.

4.4 Selection of Underwriters. The Company shall have the right to select the investment banker(s) and manager(s) to administer the offering in connection with any Piggyback Registration.

-5-

5. Holdback Agreements. Each holder of Registrable Securities shall not effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, or engage in any hedging transactions relating to the same, during the 30 days prior to and the 90-day period beginning on the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration, in each case pursuant to which such holder’s Registrable Securities are included (except as part of such underwritten registration), unless the underwriters managing the registered public offering agree otherwise.

6. Registration Procedures. Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement, the Company shall use commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

6.1    prepare and file with the Commission a registration statement and such amendments and supplements as may be necessary with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective;

6.2    notify each holder of Registrable Securities of the effectiveness of each registration statement filed hereunder and prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 120 days (or until the distribution described in the registration statement has been completed) (or, in the case of a Shelf Registration, a period ending on the earlier of (i) the date on which all Registrable Securities have been sold pursuant to the Shelf Registration or have otherwise ceased to be Registrable Securities, and (ii) the 24-month anniversary of the effective date of such Shelf Registration) and comply with the provisions of the Securities Act with respect to the disposition of securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; provided, however, that at any time, upon written notice to the participating holders of Registrable Securities and for a period not to exceed forty-five (45) days thereafter (the “Suspension Period”), the Company may suspend the use or effectiveness of any registration statement (and the holders of Registrable Securities participating in such offering hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes that the Company may, in the absence of such suspension hereunder, be required under state or federal securities laws to disclose any corporate development the disclosure of which could reasonably be expected to have a material adverse effect upon the Company, its stockholders, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto. No more than two (2) such Suspension Periods shall occur in any twelve (12) month period. In the event that the Company shall exercise its rights hereunder, the applicable time period during which the registration statement is to remain effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive thirty (30) days with the consent of the holders of at least a majority of the Registrable Securities proposed to be sold by the holders

participating in such offering. If so directed by the Company, the holders of Registrable Securities shall use their commercially reasonable efforts to deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such holders’ possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice;

6.3    furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

6.4    use commercially reasonable efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided, however, that the Company shall not be required to (a) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (b) subject itself to taxation in any such jurisdiction or (c) consent to general service of process in any such jurisdiction);

6.5    promptly notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a reasonable number of copies of a supplement or amendment to such prospectus so that, as thereafter delivered to the sellers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading, in which event the period mentioned in Section 6.2 shall be extended by the length of the period from and including the date when each seller of such Registrable Securities shall have received such notice to the date on which each such seller has received the copies of the supplemented or amended prospectus contemplated under this Section 6.5;

6.6    cause all such Registrable Securities to be listed on each securities exchange and/or quotation system on which similar securities issued by the Company are then listed and/or quoted;

-7-

6.9    make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement;

6.10    otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company’s first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

6.11    in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Common Stock included in such registration statement for sale in any jurisdiction, the Company shall use its commercially reasonable efforts promptly to obtain the withdrawal of such order; and

6.12    use its commercially reasonable efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities.

The holders of the Registrable Securities agree to comply with any prospectus delivery and/or notice requirements under the Securities Act then in effect, and agree to not use any “free-writing” prospectus in connection with the sale of any Registrable Securities.

8. Indemnification.

8.1 In connection with any Demand Registration or Piggyback Registration, the Company agrees to indemnify, to the extent permitted by law, each holder of Registrable

-8-

Securities, the partners or officers, directors and equity holders of such holder, and each Person who controls such holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities (joint or several) and expenses incurred by such party arising out of, based upon or caused by any of the following statements, omissions or violations (each, a “Violation”): (i) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities Act, Exchange Act or any state securities laws; and the Company will reimburse each such holder, each of its partners, officers, directors and equity holders, and each Person controlling such holder for any legal or other expenses reasonably incurred, as such expenses are incurred, by any of them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case for any such loss, claim, damage, liability or action (x) to the extent that it is caused by a Violation that occurs in reliance upon and in conformity with any information furnished in writing to the Company by such holder, and stated to be specifically for use in such registration, or (y) insofar as it relates to any untrue or alleged untrue statement of material fact, or any omission or alleged omission of a material fact required to be stated in the registration statement or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, made in a preliminary prospectus on file with the Commission at the time the registration statement becomes effective or the amended prospectus is filed with the Commission pursuant to Rule 424(b) (the “Final Prospectus”), if a copy of the Final Prospectus was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act, and if the Final Prospectus would have cured the defect giving rise to the loss, liability, claim or damage.

8.2 In connection with any Demand Registration or Piggyback Registration in which a holder of Registrable Securities is participating, each such holder agrees to indemnify, to the extent permitted by law, the Company, its directors, officers, any other holder selling securities in such Demand Registration or Piggyback Registration, and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities (joint or several) and expenses arising out of, based upon or caused by any Violation, but only (i) to the extent that such Violation is caused by any information furnished in writing by such holder, and stated to be specifically for use in such registration, or (ii) insofar as they relate to any untrue or alleged untrue statement of material fact, or any omission or alleged omission of a material fact required to be stated in the registration statement or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, made in a preliminary prospectus on file with the Commission at the time the registration statement becomes effective or the Final Prospectus is filed with the Commission, if a copy of the Final Prospectus was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act, and if the Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage; and such holder will reimburse the Company and each such Person for any legal or other expenses reasonably incurred, as such expenses are incurred, by any of them in connection with investigating or defending any such loss, claim, damage, liability or expense; provided, that, the obligation to

-9-

indemnify shall be individual, not joint and several, for each holder and shall be limited to the net amount of proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement.

8.3 Any Person entitled to indemnification hereunder shall (a) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party’s ability to defend such claim), and (b) unless in the written opinion of legal counsel to such indemnified or indemnifying parties a conflict of interest between such indemnified and indemnifying parties exists with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall be obligated to pay the fees and expenses of one counsel (but not more than one) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment (with written advice of counsel) of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.

8.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any partner, officer, director or controlling Person of such indemnified party and shall survive the transfer of securities. Each party also agrees to make such provisions, as are reasonably requested by the other party, for contribution in the event the indemnification provided for in this Agreement is unavailable for any reason.

9. Participation in Underwritten Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Company and (b) completes and executes all questionnaires, powers of attorney and other documents reasonably required under the terms of such underwriting arrangements; provided, that, no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such holder and such holder’s intended method of distribution) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto, except to the extent of the indemnification provided in Section 8.

10. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of any Registrable Securities to the public without registration after the 18-month anniversary of the Closing Date, the Company agrees to use commercially reasonable efforts to:

10.1 File, as and when applicable, with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and
