CFO David Patir resigns to pursue other business opportunities

Mr. Rinberg, Chief Executive Officer, said that Mr. Mandelker possesses extensive experience in the oil and gas exploration industry in both the United States and Israel and, with his coming in house as a full-time employee, Zion's management team will be greatly strengthened. Mr. Rinberg praised Mr. Mandelker's work in his previous role as Zion's outside general counsel, especially his contribution to the success of Zion's recent IPO, and said that he looked forward to his future contribution to the company.

Mr. Rinberg also announced that, on June 1, 2007, the company was notified by its CFO, David Patir, that having helped the Company through the successful conclusion of its IPO, Mr. Patir wished to resign as the company's CFO.

Mr. Rinberg said that Mr. Patir, having served as Zion's CFO during the past two years, wished to pursue other business opportunities. Mr. Rinberg thanked Mr. Patir for his services to Zion and wished him well with his future activities. Mr. Rinberg also said that the company had commenced discussions with a candidate to replace Mr. Patir as the company's CFO.

Zion Oil & Gas, a Delaware corporation, explores for oil and gas in Israel, onshore between Tel Aviv and Haifa. In 2005, Zion drilled an exploratory well on its 99,000 acre Ma'anit-Joseph License to a total depth of 15,842 feet. It is currently carrying out completion activities on that well and is preparing to drill an appraisal and deep test well, the Ma'anit-Rehoboth #2, on that License.

Zion has been notified by the Israeli Petroleum Commissioner's office that its application for an 81,000 acre petroleum exploration license north of its Ma'anit-Joseph License, and tentatively denominated the Asher-Menashe License, has been granted.

In the event of a commercial discovery, following recovery of certain exploratory costs, Zion intends to donate 6% of its gross revenues from its Israeli petroleum rights to two charitable trusts to be established by Zion, one in Israel and one in the U.S.
