The other terms of said direct license shall be in accordance with the terms of this License but shall also allow the retention of CELUNOL as a consultant provided that CELUNOL consents and did not prior to the termination breach any of its obligations of confidentiality.

In consideration for the exclusive rights and license granted hereunder to CELUNOL, CELUNOL will pay KGSI:

a. [***] Dollars (US$[***]) in the following installments:

[***] Dollars (US$[***]), due and payable within ten (10) business days from the date that is [***] from the Effective Date.

Each installment shall be creditable against royalties accrued for the production of fuel grade ethanol using KGSI Technology or KGSI Technical Information, as provided in Section 4 c herein below, during the [***] period preceding that installment.

-9-

c. A royalty based solely on the production of fuel grade ethanol using KGSI Technology or KGSI Technical Information by CELUNOL and its sublicensees of $[***] per gallon of fuel grade ethanol until a total of [***] gallons of fuel grade ethanol have been produced using KGSI Technology or KGSI Technical Information in the [***] of the Effective Date and every following [***] of the Effective Date, and thereafter the royalty rate will become $[***] per gallon for the remainder of that [***] period.

d. All fees, royalties, and other payments due to KGSI under the Agreement shall be made in United States Dollars. All royalties owing with respect to production of fuel grade ethanol or sublicensing revenue payable to KGSI stated in currencies other than U.S. dollars shall be converted at an exchange rate that is the arithmetic mean of the opening telegraphic transfer selling and buying rate published by the American East Coast edition of the Wall Street Journal on the day preceding the due date of payment.

When in any country the law or regulation prohibits both the transmittal and the deposit of royalties on sales in that country, royalty payments from that country will be suspended for as long as the prohibition is in effect and, as soon as the prohibition ceases, all royalties that CELUNOL or its Affiliates or sublicensees would have been obligated to pay, but for the prohibition, will promptly be deposited or transmitted, as the case may be, to the extent then allowed.

Commencing on the date, which is the first day of the month immediately following thirty six (36) months form the Effective Date (“the initial reporting period”) and the end of each subsequent twelve (12) months thereafter (“the subsequent twelve month reporting period”), CELUNOL shall have a sixty (60) day period within which it shall deliver to KGSI (i) a yearly statement setting forth the amount (in gallons) of fuel grade ethanol produced using KGSI Technology or KGSI Technical Information and the total amount of royalties due for the initial reporting period or subsequent twelve month reporting period, as the case may be, and (ii) payment of the annual installment specified in Section 4 b hereinabove and all royalties due in accordance with Section 4c hereinabove after applying a credit equal to the amount of said annual installment by way of electronic transfer to a bank account nominated by KGSI for that purpose.

b. CELIJNOL agrees to make and keep full and accurate books and records including but not limited to full and accurate books and records in relation to all sublicensees in sufficient detail to enable royalties payable to KGSI hereunder to be determined. CELUNOL agrees to keep such books and record available for a period not less than six years. KGSI shall have the right to appoint an independent accounting firm (“KGSI Independent Auditor”). reasonably acceptable to CELUNOL, to conduct a special audit of only those books and records of CELUNOL that pertain to the calculation of royalties due for the period being audited. Upon thirty (30) days prior written notice to CELUNOL and on a date and time during normal business hours acceptable to CELUNOL, but no more than once in respect of any calendar year, the KGSI Independent Auditor shall have full access to said books and records of CELUNOL to conduct said special audit, and the KGSI Independent Auditor shall have the right to make copies therefrom at KGSPs expense. The KGSI Independent Auditor shall treat all information obtained in such audit as Confidential Information and shall not disclose the same to KGSI or others, except that the KGSI Independent Auditor may disclose to KGSI such information as may

-11-

pertain to the calculation of royalties due hereunder. Prompt adjustment shall be made to reflect the results of such audit. If it is determined following such audit that the amount of royalties due for the period covered by such audit was understated by CELUNOL by at least [***] percent ([***]%), then CELUNOL shall reimburse KGSI for the reasonable out-of-pocket costs of such audit incurred by KGSI within thirty (30) days after KGSI’s demand therefor. Nothing contained herein is intended to waive or limit CELUNOL’s right to contest the accuracy of any audit undertaken by KGSI. Furthermore CELIJNOL shall impose similar audit obligations on its sublicensees and it will, at the request of KGSI, have a sublicensee audited at the expense of KGSI and, in such case, provide KGSI with any reimbursement of audit costs, which it may receive from its licensee.

The receiving Party, its agents and employees shall not use such information for any purpose other than in connection with exercising their rights or discharging their obligations under the terms of the Agreement. This Section 6 shall also apply to any consultants or subcontractors that the receiving Party may engage in connection with the Agreement, except that this Section 6 shall not apply to any consultants or sub-contractors who are engaged by CELUNOL and to whom neither the KGSI Technology nor the KGSI Technical Information has been disclosed by CELUNOL or otherwise made available by CELIJNOL.

This shall include making or allowing the disclosing Party to make appropriate motions for a protective order or taking other steps to protect the confidentiality of the information to be disclosed and seeking additional time to comply. Should disclosure be required to further the business objectives of the receiving party, such as disclosure to regulatory authorities from whom the receiving Party is seeking a license or other permit, the efforts to preserve confidentiality in the hands of such governmental authority shall be at the expense of the receiving Party.

c. In the event that CELUNOL desires to obtain a permit or license to pursue activities in the Field from a governmental authority which has the procedures and capacity to maintain disclosures to it confidential and which requires the disclosure of KGSI Confidential Information in order to obtain such permit or license, CELUNOL may request consent for such disclosure from KGSI, which consent will not be unreasonably withheld, However, such consent shall be conditioned on CELUNOL complying with the procedures of the governmental authority necessary to insure that the confidentiality of the disclosed information is maintained.

d. Any legal requirement that any of the confidential terms of this Agreement be disclosed shall be communicated by the Party subject to such requirement to the other Party as soon as the requirement arises or is recognized by the obligated Party.
