Zion Oil & Gas - Special Alert

June 21, 2010
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dear Shareholder and/or Friend of Zion


Rights Offering to Terminate on June 30, 2010


There are only eight business days left until the termination of Zion's rights offering, so if you do wish to take advantage of this opportunity... it is now or never.

As William Shakespeare wrote,

"There is a tide in the affairs of men, Which, taken at the flood, leads on to fortune; Omitted, all the voyage of their life Is bound in shallows... On such a full sea are we now afloat..."
 
 
Over 2,750 people have watched our latest film in which we discuss our goal to establish Zion Drilling, Inc. If you haven't, please take a few minutes to do so - to watch the film, please click here.

 
RIGHTS OFFERING

Under the rights offering (see www.zionoil.com/investor-center) Zion stockholders, at the close of business on May 6, 2010, were issued, at no charge, the following

ONE subscription right for every TWO shares of stock owned (as of the close of business on May 6, 2010).


 
Each subscription right entitles the holder to purchase one share of Zion stock at a price of $5.00, irrespective of the market price at the time of purchase.

The subscription rights may be exercised at any time prior to the end of June 2010. However, after 5:00 pm EDT on June 30, 2010, unexercised subscriptions rights will expire with no residual value.

Please note that if you want to exercise your rights and you hold your stock in a brokerage account, then you will need to contact your broker to determine when and how you can exercise your rights, as each individual brokerage firm has their own timeline and procedures for processing subscriptions.

As detailed in the press release, we plan to use the proceeds from the rights offering: (a) to purchase a 51% interest in a new yet to be established company (Zion Drilling, Inc. that will own a 2,000 horsepower drilling rig), (b) to drill further 'deep' exploration wells on Zion's licenses in Israel (in continuation of Zion's oil and gas exploration efforts) and (c) for general corporate purposes.

This opportunity is only available until June 30, 2010.


"In your good pleasure, make Zion prosper..."

Psalm 51:18


Thank you for your support of Zion, and

Shalom from Israel

Richard Rinberg

CEO of Zion Oil & Gas, Inc.
