Reader Advisory:
This news release contains certain forward‐looking statements, which include assumptions with respect to future operations. The reader is cautioned that assumptions used in the preparation of such information may prove to be incorrect. All such forwardlooking statements involve substantial known and unknown risks and uncertainties, certain of which are beyond the Company’s control. Such risks and uncertainties include, without limitation, risks associated with oil and natural gas exploration, development, exploitation, production, marketing and transportation, volatility of commodity prices, availability of drilling rigs and other services, delays resulting from or inability to obtain required regulatory approvals and ability to access sufficient capital from internal and external sources, the impact of general economic conditions in Canada and the United States, industry conditions, changes in laws and regulations (including the adoption of new environmental laws and regulations) and changes in how they are interpreted and enforced, the lack of availability of qualified personnel or management, fluctuations in foreign exchange or interest rates, and stock market volatility. The Company’s actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward‐looking statements and, accordingly, no assurances can be given that any of the events anticipated by the forward‐looking statements will transpire or occur, or if any of them do, what benefits, including the amount of proceeds, the Company will derive there from. Readers are cautioned that the foregoing list of factors is not exhaustive.

BOE’s may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
