INFORMATION TO BE INCLUDED IN THE REPORT

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(c) On May 22, 2012, Lucien Bronicki, David Wagener and Roger W. Gale resigned from the board of directors of Ormat Technologies, Inc. (the “Company”). As a result of the resignations, Mr. Bronicki is no longer Chairman of the board of directors or a member of the Nominating and Corporate Governance Committee, Mr. Gale is no longer a member of the Audit Committee and Mr. Wagener is no longer a member of the Nominating and Corporate Governance Committee.

(d)(1) The board of directors appointed Gillon Beck, Ami Boehm, David Granot and Robert E. Joyal as directors of the Company to fill vacant seats on the board of directors, effective May 22, 2012.

(d)(2) Each of the new directors was nominated by certain shareholders of Ormat Industries Ltd. (“OIL”), our parent company. The nominations were made pursuant to a Shareholder Rights Agreement dated May 22, 2012 (the “BIL FIMI Shareholders Agreement”) among Bronicki Investments Ltd., an Israeli company (“BIL”), FIMI ENRG, an Israeli limited partnership and FIMI ENRG, L.P. a Delaware limited partnership (collectively “FIMI”). BIL is controlled by three of the Company’s named executive officers, Lucien Bronicki, Yehudit Bronicki and Yoram Bronicki. As noted above, Lucien Bronicki resigned as a director of the Company on May 22, 2012, and Yehudit Bronicki and Yoram Bronicki continue to serve as directors of the Company. Neither the Company nor OIL is a party to the BIL FIMI Shareholders Agreement.

The BIL FIMI Shareholders Agreement provides, among other things, that to the maximum extent permitted by applicable law and subject to applicable fiduciary duties, BIL and FIMI will use their reasonable efforts to cause an equal number of designees of BIL and FIMI to be elected or appointed to the boards of directors of OIL and its active subsidiaries, including the Company. The provisions concerning the Company’s board of directors generally contemplate that it would have eight members, with four nominated by BIL and four nominated by FIMI, and that two of the directors nominated by each of BIL and FIMI would need to qualify as independent directors. That board composition would be subject to change in certain cases. For example, if the Company was required to have a majority of independent directors, the board of directors would be expanded to ten and each of BIL and FIMI would nominate an additional director who qualifies as independent. In addition, the number of directors which BIL or FIMI may nominate would be subject to adjustment for relative changes, within ranges, in the amount of OIL ordinary shares held by BIL and FIMI. Each of the new directors was designated by FIMI under the BIL FIMI Shareholders Agreement and evaluated by the Company’s Nominating and Corporate Governance Committee and disinterested directors.

The appointment of the new directors and the resignation of the Company directors described above was contingent upon consummation of a sale by BIL to FIMI of certain ordinary shares of OIL owned by BIL. As set forth in the attached press release, OIL informed the Company that sale was consummated on May 22, 2012.
