Forward-Looking Information

This press release contains information that constitutes "forward-looking information" or "forward-
looking statements" (collectively "forward-looking information") within the meaning of applicable
securities legislation. This forward-looking information includes, among others, statements regarding:

- business strategy and plans;

- expected sale of a subsidiary of Talisman and timing; and

- other expectations, beliefs, plans, goals, objectives, assumptions, information and statements about
possible future events, conditions, results of operations or performance.

Often, but not always, forward-looking information uses words or phrases such as: "expects", "does not
expect" or "is expected", "anticipates" or "does not anticipate", "plans" or "planned", "estimates" or
"estimated", "projects" or "projected", "forecasts" or "forecasted", "believes", "intends", "likely",
"possible", "probable", "scheduled", "positioned", "goal", "objective" or states that certain actions,
events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved.

Various assumptions were used in drawing the conclusions or making the forecasts and projections
contained in the forward-looking information contained in this press release. Information regarding
oil and gas reserves, business plans for drilling, exploration, development, and appraisal assumes
that the extraction of crude oil, natural gas and natural gas liquids remains economic.

Undue reliance should not be placed on forward-looking information. Forward-looking information is
based on current expectations, estimates and projections that involve a number of risks which could
cause actual results to vary and in some instances to differ materially from those anticipated by
Talisman and described in the forward-looking information contained in this press release. The
material risk factors include, but are not limited to uncertainties as to the availability and cost of
financing and changes in capital markets, the possibility that government policies or laws may change
or governmental approvals may be delayed or withheld and the abilities of the parties to complete the
transactions generally.

The foregoing list of risk factors is not exhaustive. Additional information on these and other
factors which could affect the Company's operations or financial results are included in the Company's
most recent Annual Information Form and Annual Financial Report. In addition, information is available
in the Company's other reports on file with Canadian securities regulatory authorities and the United
States Securities and Exchange Commission (SEC).

Forward-looking information is based on the estimates and opinions of the Company's management at the
time the information is presented. The Company assumes no obligation to update forward-looking
information should circumstances or management's estimates or opinions change, except as required by
law.

Reserves Data and Other Oil and Gas 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 disclosure in accordance with US disclosure requirements. The information provided by Talisman
may differ from the corresponding information prepared in accordance with Canadian disclosure
standards under National Instrument 51-101 (NI 51-101). Talisman's proved reserves have been
calculated using the standards contained in Regulation S-X of the SEC. US practice is to disclose net
proved reserves after deduction of estimated royalty burdens, including net profits interests.
Talisman makes additional voluntary disclosure of gross proved reserves. Further information on the
differences between the US requirements and the NI 51-101 requirements is set forth under the heading
'Note Regarding Reserves Data and Other Oil and Gas Information' in Talisman's Annual Information
Form. The exemption granted to Talisman also permits it to disclose internally evaluated reserves
data. Any reserves data in this press release reflects Talisman's estimates of its reserves. While
Talisman annually obtains an independent audit of a portion of its reserves, no independent qualified
reserves evaluator or auditor was involved in the preparation of the reserves data disclosed in this
press release.

McfE Conversion

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

Gross Production

Talisman makes reference to production volumes throughout this press release. Where not otherwise
indicated, 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.
