Schedule 13D

This Amendment No. 2 (“Amendment”) amends and supplements the Schedule 13D filed with the U.S. Securities and Exchange Commission (the “SEC”) on September 2, 2015, as previously amended by the Schedule 13D/A filed with the SEC on March 21, 2016 (the “Schedule 13D”).

This Amendment is the Filers’ final amendment to the Schedule 13D and is an exit filing.

Except as set forth in this Amendment, the Schedule 13D remains unchanged. Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth in the Schedule 13D.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

On June 1, 2016, Westport Innovations, Inc. (“Westport”) acquired the Issuer pursuant to the Agreement and Plan of Merger by and among Westport, Merger Sub and the Issuer, dated as of September 1, 2015, as amended by Amendment No. 1 thereto, dated as of March 6, 2016 (the “Merger Agreement”). In accordance with the Merger Agreement, Merger Sub merged with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of Westport. As a result, the shares of common stock beneficially owned by the Filers were cancelled and extinguished and converted into the right to receive 2.4755 common shares of Westport for each share of the Issuer’s common stock. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer. The Filers were not required to expend any funds in connection with the foregoing, and the Filers received the same consideration per share as other shareholders of the Issuer received pursuant to the Merger Agreement.

ITEM 4. PURPOSE OF TRANSACTION

The Filers hereby add the following disclosure to Item 4:

Item 3 is incorporated by reference in this Item 4 as if fully set forth herein. As described in Item 3 above, following completion of the Merger pursuant to the terms of the Merger Agreement the Filers no longer beneficially own any securities of the Issuer.

Both the Voting Agreement and the Letter Agreement terminated at the closing of the Merger in accordance with their terms.

The Filers do not have any present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a) – (j) of Item 4 of Schedule 13D.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

(a) and (b) The beneficial ownership of the Common Stock by each Filer at the date hereof is reflected on that Filer’s cover page.

(d) and (e) Not applicable.

ITEM 6. CONTRACTS, AGREEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

Other than as described in Items 4 and 5 of this statement, to the knowledge of the Filers, none of the Filers is party to any other contracts, arrangements, understandings or relationships with respect to any securities of the Issuer, including but not limited to the transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option agreements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
