ITEM 4. PURPOSE OF TRANSACTION

Prior to the date hereof, the Filers had on file with the Securities and Exchange Commission a Schedule 13G with respect to their beneficial ownership of Common Stock, initially filed with the SEC on May 19, 2010.

On September 1, 2015, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Issuer, Westport Innovations Inc. (“Parent”) and Whitehorse Merger Sub, Inc. (“Merger Sub”). Pursuant to the terms of the Merger Agreement, Merger Sub will be merged with and into the Issuer, and as a result the Issuer will continue as the surviving corporation (the “Merger”).

As an inducement to enter into the Merger Agreement, the Filers entered into a Voting Agreement with the Issuer and Parent on September 1, 2015 (the “Voting Agreement”). Pursuant to, and subject to the terms of, the Voting Agreement, the Filers agreed, among other things, to vote 2,671,684 shares of Common Stock beneficially owned by them in favor of the adoption of the Merger Agreement and any transactions contemplated thereby, including the Merger, and against any Company Acquisition Proposal (as defined in the Merger Agreement). In addition, under the Voting Agreement, the Filers also agreed to vote 10,045,657 shares of common stock of the Parent beneficially owned by them in favor of the adoption of the Merger Agreement and any transactions contemplated thereby, including the Merger, and against any Parent Acquisition Proposal (as defined in the Merger Agreement). The Filers also agreed, subject to limited exceptions, not to transfer any shares of Common Stock beneficially owned by the Filers.

The obligations in the Voting Agreement will terminate upon the earlier of the mutual written consent of the Issuer, the Parent and the Filers, the effective time of the Merger, any termination of the Merger Agreement, and the delivery of written notice of termination by the Filers to Parent and the Issuer following any Fundamental Amendment of the Merger Agreement (defined to include, among other things, an amendment to, or waiver or other modification by the Issuer or the Parent of any provision of the Merger Agreement that reduces the amount of the merger consideration or changes the form of the merger consideration).

The foregoing summary of the principal terms of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the full copy of the Voting Agreement filed as Exhibit 10.1 to the Form 8-K filed by the Issuer on September 2, 2015 and incorporated herein by reference.

No additional consideration was paid by or to Parent, Merger Sub, the Issuer, or the Filers in connection with the Voting Agreement, and therefore no funds were used in connection with the transactions requiring the filing of this statement.

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, except as set forth herein or such as would occur upon completion of any of the actions discussed herein.
