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 or strategy are included in Talisman's most recent Annual Information Form. 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. 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.

Oil and Gas Information

Reserves

National Instrument 51-101 ("NI 51-101") of the Canadian Securities Administrators imposes oil and gas disclosure standards for Canadian public companies engaged in oil and gas activities. Talisman has obtained an exemption from Canadian securities regulatory authorities to permit it to provide certain disclosures in accordance with the US disclosure standards, in addition to the disclosure mandated by NI 51-101, in order to provide for comparability of oil and gas disclosure with that provided by US and other international issuers. Accordingly, in addition to the reserves data and certain other oil and gas information included in this news release which is provided in accordance with NI 51-101, there is data and information provided in accordance with US disclosure standards.

A separate exemption granted to Talisman also permits it to disclose internally evaluated reserves data. Any reserves and resources data contained in this news release reflects Talisman's estimates of its reserves and resources. While Talisman annually obtains an independent audit of a portion of its proved and probable reserves, no independent qualified reserves evaluator or auditor was involved in the preparation of the reserves and resources data disclosed in this news release.

Production and Reserves Volumes

Unless otherwise stated, production volumes and reserves estimates are stated on a Company interest basis prior to the deduction of royalties and similar payments. In the US, net production volumes and reserve estimates are reported after the deduction of these amounts. US readers may refer to the table headed "Continuity of Net Proved Reserves" in Talisman's most recent Annual Information Form for a statement of Talisman's net production volumes and reserves. The use of the word "gross" in this news release means a 100% interest prior to the deduction of royalties and similar payments.

Resources

In this news release, Talisman also discloses contingent resources, prospective resources and PIIP as at February 28, 2013. Where not otherwise indicated, in this news release, the contingent resources provided are 2C and the prospective resources provided are unrisked best estimates.

Contingent resources are defined as those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. The contingencies that prevent the resources from being classified as reserves are: lack of gas sales contract; additional testing; production and performance appraisal activities; development time frame too far in the future; demonstration of economic viability; facilities and egress; access to equipment and services; hydraulic fracturing technology; commodity prices and regulatory approvals. There is no certainty that it will be commercially viable to produce any portion of the resources. In addition to these contingencies and uncertainties the development of commerciality of resources is also subject to a number of risk factors, as discussed more fully above.
