Re: Alliance Agreement; Future Collaboration

Dear Mr. Kim,

With this letter, MTI and Samsung each hereby (i) acknowledges and agrees that the other has no outstanding obligations and (ii) releases the other from any and all claims, in each case under the Alliance Agreement between the parties dated May 16, 2006, including all exhibits and amendments thereto (the “Agreement”). Furthermore, MTI and Samsung further acknowledge the Agreement has expired as of its own terms and the only rights and obligations that survive thereunder are Sections 1, paragraphs (a), (b), (c) and (d) of 2.5, 2.9 (for the period set forth therein), 5, 6.2, 7 (for a period of six (6) years from the date of this letter), 9 and 10 of the Agreement.

Without prejudice to the foregoing, as a continuing business collaboration, MTI will provide Samsung with status updates on MTI’s development of the direct methanol fuel cell (“DMFC”). From time to time, and if mutually agreed, (i) MTI will loan production samples of the DMFC (which, for the avoidance of doubt, shall not be deemed ‘DMFC Prototypes’ as had been defined in the Agreement) to Samsung for potential commercial applications and (ii) Samsung may request changes to the product specifications. If Samsung, at its sole discretion, decides to commercialize MTI’s solution prior to July 1, 2009, Samsung may purchase commercial samples, the price of such samples to be mutually agreed.

We at MTI look forward to continuing our non-exclusive collaboration with Samsung to prepare MTI DMFC products, as suggested in the attached non-binding timetable, to meet Samsung’s needs for alternative power sources for its mobile phone products.

Notwithstanding anything to the contrary, the foregoing future collaboration conditions shall terminate no later than six (6) months after the earlier of (i) July 1, 2009 and (ii) first commercial production of DMFCs by MTI. Except as otherwise agreed by the parties in writing, each party shall bear its own fees, costs and expenses incurred in connection with this letter and the activities contemplated hereunder. Notwithstanding anything to the contrary, this letter and/or any timetables shall not constitute, nor shall it be construed to be, an obligation or commitment of any party to commence or continue with negotiations or to enter into any contract or other arrangement.

If the foregoing correctly reflects the understanding between MTI and Samsung, please so indicate by signing and returning a copy to me.

Sincerely yours,

For and on behalf of

MTI MicroFuel Cells Inc.
