 Dear Alan: 
 As part of a company-wide effort to restructure the business and
consolidate operations at a new location in New Hampshire, I would like to extend an offer to transfer your employment at Mascoma Corporation (the “Company”) to our Lebanon, New Hampshire office. 

1. Position. You will serve as SVP, Operations for the Company reporting directly to Jim Flatt. As a full-time employee of the
Company, you will be expected to devote your full business time and energies to the business and affairs of the Company.

2009 through September 30, 2010. You acknowledge that this allowance will represent taxable compensation to you and that the Company will report this income and withhold taxes, as required by law. 

5. Term and Termination. While the Company is implementing a variety of restructuring measures in an effort to ensure its success,
the Company wishes to emphasize that this relocation offer does not constitute any promise of employment for a specific period. Your employment with the Company will continue to be an “at-will” employment relationship, and may be
terminated by either party at any time for any reason, with or without cause, without notice according to the terms of paragraph 8 of the employment offer dated 11/16/07, attached.
