SUBSCRIPTION CERTIFICATE FOR RIGHTS OFFERING

FOR HOLDERS OF RECORD ON _________, 2009

ZION OIL & GAS, INC. (the “Company”) is conducting a rights offering (the “Rights Offering”) that entitles the holders of the Company’s common stock, $0.01 par value per share (the “Common Stock”), as of the close of business on _________, 2009 (the “Record Date”) to receive .375  of a subscription right (each, a “Right”) for each share of Common Stock held of record on the Record Date. No fractional shares or cash in lieu thereof will be issued or paid. Instead, the number of Rights received will be rounded up to the next largest whole number. Each whole Right entitles the holder to subscribe for and purchase one share of Common Stock (the “Basic Subscription Right”) at a subscription price of $5.00 per share.

Set forth above is the number of shares to which the holder whose name and address is set forth above is entitled to subscribe pursuant to the Basic Subscription Right. If you exercise your rights in full, you may also exercise an over-subscription right (the “Over-Subscription Right”) to purchase additional shares of Common Stock that remain unsubscribed at the expiration of the Rights Offering, subject to availability and allocation of shares among persons exercising this Over-Subscription Right. If there is a change of address and you wish to subscribe, please note the new address on Form 2.  Your records will be updated with the new information.

For a more complete description of the terms and conditions of the Rights Offering, please refer to the Company’s prospectus dated           , 2009 (the “Prospectus”), which is incorporated herein by reference. Copies of the prospectus are available upon request from the Dallas office, by phone at 0-000-000-0000 or 214-221-4610 or by e-mail at xxxxxx@xxxxxxx.xxx.

This subscription certificate (the “Rights Certificate”) must be received by us with payment in full by 5:00 p.m., New York City time, on [Expiration Date] (unless extended in the sole discretion of the Company) (as it may be extended, the “Expiration Date”). Any Rights not exercised prior to the Expiration Date will be null and void. Any subscription for shares of Common Stock in the Rights Offering made hereby is irrevocable.

The Rights represented by this Rights Certificate may be exercised by duly completing Form 1. Rights holders are advised to review the Prospectus before determining whether to exercise their Rights. In addition, if certificates representing the Common Stock are to be issued in a name other than the registered holder or are to be sent to an address other than that shown above, also complete Form 2.
