FORWARD-LOOKING STATEMENTS

Certain information set forth in this news release contains forward-looking
statements or information ("forward-looking statements"), including statements
regarding the Company's future net revenues. By their nature, forward-looking
statements are subject to numerous risks and uncertainties, some of which are
beyond Donnybrook's control, including the impact of general economic
conditions, industry conditions, volatility of commodity prices, currency
fluctuations, imprecision of reserve estimates, environmental risks, operational
risks in exploration and development, competition from other industry
participants, the lack of availability of qualified personnel or management,
stock market volatility and the ability to access sufficient capital from
internal and external sources. Although Donnybrook believes that the
expectations in our forward-looking statements are reasonable, our
forward-looking statements have been based on factors and assumptions concerning
future events which may prove to be inaccurate. Those factors and assumptions
are based upon currently available information. Such statements are subject to
known and unknown risks, uncertainties and other factors that could influence
actual results or events and cause actual results or events to differ materially
from those stated, anticipated or implied in the forward looking information. As
such, readers are cautioned not to place undue reliance on the forward looking
information, as no assurance can be provided as to future results, levels of
activity or achievements. The risks, uncertainties, material assumptions and
other factors that could affect actual results are discussed in our Annual
Information Form and other documents available at www.sedar.com. Furthermore,
the forward-looking statements contained in this document are made as of the
date of this document and, except as required by applicable law, Donnybrook does
not undertake any obligation to publicly update or to revise any of the included
forward-looking statements, whether as a result of new information, future
events or otherwise. The forward-looking statements contained in this document
are expressly qualified by this cautionary statement. This news release shall
not constitute an offer to sell or the solicitation of any offer to buy
securities in any jurisdiction.


Where amounts are expressed on a barrel of oil equivalent ("BOE") basis, natural
gas volumes have been converted to oil equivalence at six thousand cubic feet
per barrel. The term BOE may be misleading, particularly if used in isolation. A
BOE conversion ratio of six thousand cubic feet per barrel is based on an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead. References to oil in this
discussion include crude oil and natural gas liquids ("NGLs"). NGLs include
condensate, propane, butane and ethane. References to gas in this discussion
include natural gas.
