ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Extension of Joseph Petroleum Exploration License

On April 22, 2010, the Israeli Petroleum Commissioner notified Zion Oil & Gas, Inc. (the "Company" or “Zion”) that it was approving the Company’s request for a one-year extension on the Company’s Joseph License, extending the expiration date of the Joseph License until October 10, 2011.

The Company’s “Joseph License” covers approximately 83,272 acres on the Israeli coastal plain south of the Asher-Menashe License between Caesarea in the north and Netanya in the south.  The Joseph License had an initial three-year term that ran from October 10, 2007 through October 10, 2010, and has now been extended for an additional one-year period ending October 10, 2011. At the option of the Israeli Petroleum Commissioner, the Joseph License may be extended for additional one-year periods up to 2014.

Under the terms of the Joseph License, as extended, Zion is required (i) to submit to the Israeli Petroleum Commissioner a report as to the production testing of Zion’s Ma’anit-Rehoboth #2 well by October 1, 2010 and (ii) to start drilling, by January 1, 2011, a well to the Permian geological layer.

The Company is in the process of preparing for submission to the Israeli Petroleum Commissioner the production reports relating to the Ma’anit-Rehoboth #2 well and has previously disclosed its plans to drill the Ma’anit-Joseph #3 well to test the Permian geological formation, both of which are located within the Joseph License area. The Company has started the permitting process for the Ma’anit-Joseph #3 well.

Attached, as Exhibit 10.1, is an English translation from the original Hebrew of the extension letter.
