Under the terms of the Megiddo-Jezreel License, the Company is to identify and
submit a drilling prospect in the license area by July 1, 2015; enter into a
contract for the drilling of such prospect by October 1, 2015; and begin
drilling or "spud" a well to a minimum proposed total depth of approximately
4,000 meters (~ 13,125 feet) by December 1, 2015. Additional terms of the
License require Zion to attain various geological and geophysical milestones
during the primary term, including reprocessing and acquiring additional
seismic data, all of which should be achievable before the stated deadlines.

The new license award follows the Company's submission in April of 2013 of a
detailed and extensive application proposal seeking the Petroleum Exploration
License in the Megiddo-Jezreel Valley area.

John Brown, Zion's CEO, said, "This is a key milestone in Zion's future
exploration success. We are committed to stay the course and fulfill Zion's
vision to render assistance to the Jewish people and Nation of Israel and to
aid them in the Restoration of the Land by providing the oil and gas necessary
to help the People of Israel maintain their political and economic
independence."

Victor G. Carrillo, Zion's President and Chief Operating Officer, said, "Being
awarded the 98,842 acre Megiddo-Jezreel Valley License is a critically
important step for Zion's future exploration efforts. We have many
prerequisite steps before we can drill our next deep exploratory well but we
plan to get to that point as expeditiously as possible. This new area appears
to have all of the geologic ingredients of an active petroleum system with
good potential."
