CORPORATE PRESENTATION April 2012

FORWARD LOOKING STATEMENT This presentation includes a number of forward - looking statements that reflect the current views of our management with respect to future events and financial performance. You can identify these statements by forward - looking words such as “may,” “will,” “expect,” “anticipate,” “believe,” “estimate” and “continue,” or similar words. Those statements include statements regarding our and m emb ers of our management team’s intent, belief or current expectations as well as the assumptions on which such statements are based. P ros pective investors are cautioned that any such forward - looking statements are not guarantees of future performance and involve risk and uncertainties, and that actual results may differ materially from those contemplated by such forward - looking statements. Readers are urged to carefully review and consider the various disclosures made by us in these materials and our other report s f iled with the U.S. Securities and Exchange Commission. These presentation materials should be read in conjunction with the sections ent itl ed “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10 - K, and with our “Consolidated Financial Statements” and notes thereto in our Annual Report on Form 10 - K for the year ended January 31, 2012. Important factors currently known to our management could cause actual results to differ materially from those in forward - lookin g statements. We undertake no obligation to update or revise forward - looking statements to reflect changed assumptions, the occurr ence of unanticipated events or changes in the future operating results over time. We believe that these assumptions are based upon r eas onable data derived from and known about our business and operations. No assurances are made that actual results of operations or th e r esults of our future activities will not differ materially from these assumptions. Factors that could cause differences include, but ar e n ot limited to, history of losses, uncertainty of drilling results, inability to acquire additional leasehold interests or other oil and natu ral gas properties, inability to manage growth in our business, inability to control properties we do not operate, inability to protect against c ert ain liabilities associated with our properties, lack of diversification, substantial capital requirements and limited access to additional ca pit al, competition in the oil and natural gas industry, global financial conditions, oil and natural gas realized prices, seasonal w eat her conditions, marketing and distribution of oil and natural gas, the influence of our significant stockholders, government regu lat ion of the oil and natural gas industry, potential regulation affecting hydraulic fracturing, environmental regulations, including climate c han ge regulations, uninsured or underinsured risks, aboriginal claims, defects in title to our oil and natural gas interests, material weakness in our internal accounting controls, and foreign currency exchange risks. Prior to 2010, the SEC generally permitted oil and gas companies, in their filings, to disclose only proved reserves that a c omp any has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing econ omi c and operating conditions. Beginning with year - end reserves for 2009, the SEC permits the optional disclosure of probable and possib le reserves. We use the terms “estimated ultimately recoverable,” or EUR, “resource potential,” “recoverable reserves” or other descriptio ns of volumes of hydrocarbons to describe volumes of resources potentially recoverable through additional drilling or recovery techniques t hat the SEC’s guidelines prohibit us from including in filings with the SEC. Estimates of resource potential, recoverable reserves or esti mat ed ultimately recoverable amounts do not reflect volumes that are demonstrated as being commercially or technically recoverable. Even if c omm ercially or technically recoverable, a significant recovery factor would be applied to these volumes to determine estimates of volumes of proved reserves. Accordingly, these estimates are by their nature more speculative than estimates of proved reserves and accordingl y a re subject to substantially greater risk of being actually realized by us. The methodology for resource potential, recoverable reserves or es timated ultimately recoverable amounts may also be different than the methodology and guidelines used by the Society of Petroleum Eng ine ers and is different from the SEC’s guidelines for estimating probable and possible reserves. Furthermore, the forward - looking statements contained in this presentation are made as of the date hereof, and we undertake no o bligation, except as required by applicable securities legislation, to update publicly or to revise any of the included forward looking sta tements, whether as a result of new information, future events or otherwise. The forward - looking statements contained herein are expressl y qualified by this cautionary statement.
