WHEREAS, NHSc and Codexis desire to amend the Agreement to include a new mechanistic study to be performed after the conclusion of the Phase Ia Clinical Trial;

NOW, THEREFORE in consideration of the foregoing and the mutual agreements set forth below, the Parties agree as follows:

ARTICLE 1 DEFINITIONS

Definitions. The terms in this Amendment No. 1 with initial letters capitalized, whether used in the singular or the plural, shall have the respective meanings either set forth below or in another part of this Agreement.

ARTICLE 2

AMENDMENTS TO THE AGREEMENT

As of the Amendment No. 1 Effective Date, the Parties agree to amend the Agreement as follows:

1. The Development Plan attached as Exhibit A to the Agreement is amended by the addition of the activities set out in the Mechanistic Study Development Plan attached as Exhibit A to this Amendment No. 1.

2. Section 2.1.3 of the Agreement is amended to read in its entirety as follows:

2.1.3 Expiration of Option. The Option shall expire on the date that is forty (40) days after the Option Trigger Date if the Option Exercise has not occurred prior thereto or, if NHSc determines that a filing under the HSR Act is required in connection with the Option Exercise, if the Parties have
