DALLAS and CAESAREA, Israel, March 27, 2013 (GLOBE NEWSWIRE) -- Zion Oil & Gas, Inc. (Nasdaq:ZN) today announced the introduction of a Dividend Reinvestment and Common Stock Purchase Plan for existing shareholders and prospective investors. The Plan allows investors to purchase shares of Zion's common stock directly from the Company and reinvest cash dividends (when and if Zion pays dividends in the future), without the payment of fees and commissions typically charged by stockbrokers for small transactions. Registered stockholders and other interested first-time investors can enroll in the Plan by simply completing and submitting an enrollment form. The minimum initial investment is $250 for new investors. Once enrolled in Plan, investors may make additional investments of $50 or more through automatic deductions from checking accounts or through optional cash investments. In addition, for a limited time period through August 30, 2013, investors can also purchase units of Zion's securities, with each unit comprised of one share of common stock and one warrant to purchase an additional share of Zion's common stock. The Plan will be administered by Registrar and Transfer Company of Cranford, New Jersey (the "Plan Agent"), which also serves as the Company's stock transfer agent. Stockholders and other interested parties may obtain a copy of the Plan prospectus and an enrollment form by contacting the Plan Agent by telephoning 1-800-368-5948 or visiting the Plan Agent's website at www.rtco.com .
