FORWARD-LOOKING STATEMENTS

This press release contains forward-looking statements. More particularly, this press release contains statements concerning the anticipated dates for the closing of the financing and the anticipated uses of the net proceeds of the Offering.

The forward-looking statements contained in this document are based on certain key expectations and assumptions made by Donnybrook, including: (i) with respect to the anticipated closing date of the Offering, expectations and assumptions concerning timing of receipt of required regulatory approvals and third party consents and the satisfaction of other conditions to the completion of the Offering, and (ii) with respect to the remaining forward-looking statements, expectations and assumptions concerning the success of future drilling activities.

Although Donnybrook believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because Donnybrook can give no assurance that they will prove to be correct. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. These include, but are not limited to, the failure to obtain necessary regulatory approvals or satisfy the conditions to closing the financing, risks associated with the oil and natural gas industry in general (e.g., operational risks in development, exploration and production; delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, and health, safety and environmental risks), commodity price and exchange rate fluctuations changes to existing laws and regulations and uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. The forward-looking statements contained in this document are made as of the date hereof and Donnybrook undertakes no obligation to update publicly or revise any forward-looking statements or information, whether as a result of new information, future events or otherwise, unless so required by applicable securities laws.
