Zion Oil & Gas Posts Preliminary Results for Rights Offering

Zion Oil & Gas announced the preliminary results of its rights offering to stockholders, offering 3.6 million shares of Zion's common stock at a subscription price of $5.00 per share. The rights offering terminated yesterday, November 30, 2009, as originally scheduled. Preliminary results indicate that subscriptions were received for over $37 million, significantly greater than the maximum available of $18 million.

The total available subscription of 3.6 million shares, for gross proceeds of $18 million, will be accepted by Zion and amounts for the unfilled oversubscriptions will be refunded as soon as possible. As detailed in the prospectus, oversubscription rights will be allocated pro rata in accordance with the number of basic subscriptions rights exercised.

Zion's Chief Executive Officer, Richard Rinberg, said today, "I am pleased to announce the successful conclusion of our rights offering. The significant oversubscription is very gratifying and shows the high level of interest in our oil and gas exploration work in Israel. The $18 Million proceeds will provide us with financial and operating flexibility and will enable us to significantly further our exploration and drilling program."

Under the completed rights offering, holders of record of Zion's common stock, as of the close of business on October 19, 2009, were given non-transferable subscription rights to purchase up to 3.6 million shares of common stock at a subscription price of $5.00 per share.
