Item 3 is hereby amended and restated to read as follows:

The Shares purchased by JCP Partnership and JCP Drawdown III were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted. The aggregate purchase price of the 938,360 Shares owned directly by JCP Partnership is approximately $3,281,456, including brokerage commissions. The aggregate purchase price of the 1,916,588 Shares owned directly by JCP Drawdown III is approximately $8,724,372, including brokerage commissions.

Mr. Pappas has also been awarded an additional 8,166 options that do not vest within the next 60 days.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On January 24, 2018, JCP Management and certain of its affiliates (collectively, “JCP”) entered into a voting agreement (the “Voting Agreement”) with Ormat Nevada Inc., a Delaware corporation (“Ormat”), in connection with that certain Agreement and Plan of Merger (the “Merger Agreement”), dated January 24, 2018, by and among Ormat, OGP Holding Corp., a Delaware corporation and wholly-owned subsidiary of Ormat (“Merger Sub”), and the Issuer, pursuant to which Merger Sub will merge with and into the Issuer (the “Merger”), with the Issuer continuing as a subsidiary of Ormat. Under the terms of the Merger Agreement, stockholders of the Issuer will receive $5.45 per Share in cash. The Merger is expected to close in the second quarter of 2018, subject to the receipt of stockholder approval of the Issuer and satisfaction of customary closing conditions, including applicable regulatory approvals.

Pursuant to the Voting Agreement, JCP agreed, among other things, to vote all of the Shares it beneficially owns (and all other Shares that it may subsequently acquire) to approve the Merger and the Merger Agreement; provided, however, that JCP’s voting obligations will be suspended in the event that, and for so long as, the Issuer’s Board of Directors is not recommending that stockholders of the Issuer vote in favor of the Merger. The Voting Agreement will terminate upon the earliest to occur of (a) the effective time of the Merger, (b) the date on which the Merger Agreement is terminated in accordance with its terms and (c) the making of any change by amendment, waiver or other modification to any provision of the Merger Agreement that decreases the amount or changes the form of the Merger Consideration (as defined in the Merger Agreement).

The foregoing description of the Voting Agreement is qualified in its entirety by reference to the Voting Agreement, which is attached hereto as Exhibit 99.1 and is incorporated herein by reference. In addition, reference is made to the Merger Agreement, which is attached as Exhibit 2.1 to the Issuer’s Form 8-K filed with the Securities and Exchange Commission on January 25, 2018.
