The registrant's Quarterly Report on Form 10-Q for the three months ended March 31, 2010 could not be filed by the prescribed due date because the registrant had not yet finalized its financial statements for the quarter and the review of registrant's financial statements for the quarter is ongoing.

The registrant anticipates that the subject quarterly report will be filed on or before May 17, 2010.

(2)
Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s). x Yes ¨ No
 
(3)
Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? x Yes o No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
 
For the three months ended March 31, 2009, the registrant had a net loss of $916,000. For the three months ended March 31, 2010, the registrant estimates that it had a net loss of approximately $20,544,000.

The net loss for the quarterly period ended March 31, 2010, includes a non-cash impairment charge of approximately $19,184,000 to the registrant’s unproved oil and gas properties.  The registrant previously disclosed in its current report on Form 8-K filed on April 23, 2010, that following the completion of production testing on the Ma'anit-Rehoboth # 2 well, its management concluded that commercial quantities of hydrocarbons were not present in that well. Accordingly, the registrant expects to record the above referenced non-cash charge to its unproved oil and gas properties.

In addition to the impairment charge, the increase in net loss for the three months ended March 31, 2010 is also attributable to higher salary expenses due to expanded staff and management and higher legal and professional fees.

This Notification of Late Filing on Form 12b-25 contains forward-looking statements, including forward-looking statements relating to the Registrant's financial results for the quarter ended March 31, 2010. These statements are based on management's current expectations and involve a number of risks and uncertainties, including risks described in our filings with the Securities and Exchange Commission. The Registrant's actual results may differ materially from the Registrant's anticipated or expected results and the results in the forward-looking statements.
