Corporate Update:

Border currently has a positive working capital balance of approximately $7.3
million and an unutilized bank line of $3.5 million. Border's current total
production is approximately 230 boepd (26 percent liquids). Border's tax pool
balance as at December 31, 2012 was approximately $32.1 million with an
additional $17.5 million of successored pools primarily related to its Leduc
properties. Further, after taking into account qualifying expenditures of
approximately $1.0 million in the quarter ended March 31, 2013, the Company has
approximately $2.0 million of outstanding obligations to incur Canadian
Exploration Expenses.


Under the direction of the Special Committee, the financial advisors to the
Special Committee and management have commenced populating the virtual data room
to be used in connection with the previously announced strategic alternatives
process and continue their build out of the information package that will be
provided to interested parties. The data room and information package are
anticipated to be complete within the next seven days.


Border does not intend to disclose developments with respect to the strategic
review process unless and until the Board of Directors has approved a definitive
transaction or strategic option, or unless otherwise required by law or
disclosure of which is deemed appropriate. The Company cautions that there are
no guarantees that the strategic review will result in a transaction or if a
transaction is undertaken, as to its terms or timing.


Border currently has 332,978,953 common shares outstanding.

Forward-Looking Statements

This press release contains forward-looking statements with respect to estimates
of the quantities of proved reserves and probable reserves and related net
present values and future development costs, as well as Border's strategic
review process.


The forward-looking statements contained in this document are based on certain
key expectations and assumptions made by Border. Although Border 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 Border 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 risks associated with the oil
and 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 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 Border 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.


Notes Regarding Oil and Gas Disclosure

As used in this press release, "boe" means barrel of oil equivalent on the basis
of 6 mcf of natural gas to 1 bbl of oil. Boes 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.


It should not be assumed that the present worth of estimated future net revenue
represents the fair market value of the reserves disclosed in this press
release. The reserve and related revenue estimates set forth in this press
release are estimates only and the actual reserves and realized revenue may be
greater or less than those calculated.
