Often, but not always, forward-looking statements use words or phrases such as: "expects," "does not expect" or

current expectations, estimates and projections that involve a number of risks and uncertainties, which could
cause actual results to differ materially from those anticipated by Talisman and described in the forward-
looking statements. These risks and uncertainties include:

- the risks of the oil and gas industry, such as operational risks in exploring for, developing and producing
crude oil and natural gas, market demand and unpredictable facilities outages;

- risks and uncertainties involving geology of oil and gas deposits;

- the uncertainty of reserves estimates, reserves life and underlying reservoir risk;

- the uncertainty of estimates and projections relating to production, costs and expenses;

- potential delays or changes in plans with respect to development projects;

- risk that adequate pipeline capacity to transport the gas to market may not be available;

headings "Management's Discussion and Analysis - Risk Factors" and elsewhere in the Company's 2006 Annual

Gross Production

In this news release, Talisman makes reference to estimated production volumes. Such production volumes are
estimated on a gross basis, which means they are estimated 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

In this news release, the calculation of 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 equivalence at the wellhead.
