Item 1.02. Termination of a Material Definitive Agreement.

On December 18, 2012, Codexis, Inc. and its wholly owned subsidiary Codexis Laboratories Singapore Pte Ltd. (collectively, the "Company") received notification from the Economic Development Board of Singapore (the "EDB") that the EDB had terminated the EDB's grant to the Company pursuant to the grant letter dated as of September 28, 2009, as amended August 30, 2011 and May 22, 2012 (the "EDB Grant"). The termination by the EDB of the EDB Grant follows the Company's actions to close the Company's Singapore facility, which action is described in more detail in the Company's Current Report on Form 8-K filed on September 6, 2012 and in the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2012.

The EDB Grant provided partial support for activities in the Company's Singapore facility, which were primarily focused on pharmaceuticals and bioindustrial research and development. Under the terms and conditions of the EDB Grant, the Company was required to satisfy certain minimum staffing and performance obligations on an annual basis in order to receive disbursements from the EDB. For the fiscal years ended December 31, 2010 and 2011, the Company recognized $3.2 million and $1.3 million, respectively, in grant revenues from the EDB. For the nine months ended September 30, 2012, the Company recognized $0.6 million in grant revenues from the EDB. As a result of the EDB Grant termination, the Company will not receive any further funding from the EDB under the EDB Grant. The EDB Grant was otherwise scheduled to expire on March 31, 2013.

Through the EDB's indirect wholly owned subsidiary Biomedical Sciences Investment Fund Pte Ltd., the EDB beneficially owns approximately 8.4% of the Company's outstanding Common Stock, based on the number of shares of the Company's Common Stock outstanding as of October 31, 2012.

For additional information about the EDB Grant, see the associated grant letters and amendments thereto, filed as Exhibit 10.24 to the Company's Registration Statement on Form S-1 (File No. 333-164044), effective April 21, 2010, Exhibit 10.6 to the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2011 and Exhibit 10.1 to the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2012.
