(Amex:ZN), of Dallas, Texas and Caesarea, Israel, announced today that the company has issued 168,753 shares of common stock in the seventh round of its initial public offering.

Zion's workover operations to clean the well bore and set cement in its Ma'anit (number sign)1 well in preparation for the well's testing are proceeding according to plan.

Zion Oil & Gas, a Delaware corporation, explores for oil and gas in Israel on its Ma'anit-Joseph License and Asher Permit areas located onshore between Tel Aviv and Haifa. The net proceeds of Zion's offering are being used in part for a completion attempt on the Ma'anit (number sign)1 exploratory well drilled by Zion in 2005 to a total depth of 15,842 feet and will also be used in part to drill the currently planned appraisal and deep test well, the Ma'anit-Rehoboth (number sign)2, on our license. In the event of a commercial discovery, following recovery of certain exploratory costs, Zion intends to donate 6% of its gross revenues from the license to two charitable trusts to be established by Zion, one in Israel and one in the U.S. The common stock of Zion is traded on the American Stock Exchange under the ticker symbol "ZN".
