PART III

NARRATIVE

State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F, 10-Q, N-SAR or the transition report portion thereof could not be filed within the prescribed time period.

 Despite diligent efforts, the work necessary to complete the Company’s preparation of its financial statements, including the prior year financial restatements as described below, could not be completed without unreasonable expense and effort in sufficient time to permit the filing of its Annual Report on Form 10-KSB for the year ended March 31, 2008 on the scheduled due date of June 30, 2008.

 As described in the Company’s Current Report on Form 8-K filed on June 25, 2008, the Company identified errors in calculating the GAAP cost basis of its oil and gas properties in determining deferred tax liability for fiscal years ended March 31, 2007 and 2006 under SFAS 109 – Accounting for Income Taxes. These corrections will require restatement of the Company’s previously issued financial statements for the fiscal years ended March 31, 2007 and March 31, 2006, as well as restated interim financial information for both fiscal years. The Company expects to provide restated financial statements for the fiscal years 2007 and 2006 in its upcoming Annual Report on Form 10-KSB for the year ended March 31, 2008.

 The Company expects that it will be able to complete the work described above in time for it to file its 2008 Annual Report on Form 10-KSB on or prior to the reporting deadline provided by such extension.
