Talisman Energy Inc. (TSX: TLM) (NYSE: TLM) has agreed to sell a number of non-core assets in Canada with total proceeds of approximately C$1.9 billion, through five separate transactions.

"We are very pleased with the outcome of the sales process that we announced in January," said John A. Manzoni, President and Chief Executive Officer. "Although these are excellent assets with a great future, they can't effectively compete for capital within our emerging strategic asset mix. These sales are value accretive and will help us focus on, finance and build our growing, low-cost North American shale gas business."

These transactions include approximately one million net acres of land in the greater Peace River Arch, central Alberta Foothills and greater Hinton areas in Alberta, as well as the company's Ontario properties. The assets are currently producing 42,500 boe/d (approximately 90% natural gas), with net proved reserves of 120 mmboe. The sale equates to approximately $44,000/boe/d and $16/boe of proved reserves and seven times cash flow.

These transactions are expected to be finalized by the end of the second quarter of 2010, subject to normal regulatory approvals.

Reserves Information

Talisman's disclosure of reserves data and other oil and gas information is made in reliance on an exemption granted to Talisman by Canadian securities regulatory authorities, which permits Talisman to provide certain disclosure in accordance with US disclosure requirements. The primary differences between the US disclosure requirements and the Canadian disclosure standards under National Instrument 51-101 ("NI 51-101") are disclosed in the Company's most recent Annual Information Form.

In this news release, Talisman makes reference to production volumes. Such production volumes are stated on a gross basis, which means they are stated prior to the deduction of royalties and similar payments. In the US, net production volumes are reported after the deduction of these amounts.

Boe Conversion

Throughout this news release, barrels of oil equivalent (boe) is calculated at a conversion rate of six thousand cubic feet (mcf) of natural gas for one barrel of oil and is based on an energy equivalence conversion method. Boes may be misleading, particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl is based on an energy equivalence conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
