Transaction Rationale Accretive transaction on a cash flow, production and reserves per share basis 2006 activity and the THX transaction essentially trade GOM and Alaska for THX's onshore resource play assets Attractively valued corporate transaction provides opportunity to repeat earlier success with Wiser and other corporate transactions Additional emphasis on low risk, repeatable drilling programs Acquired assets create a larger, highly-focused onshore resource company Solidifies S. Texas and E. Texas as growth areas Adds significant Rockies position inexpensively Allows FST to apply free-cash model and cost control to THX asset base Portfolio rationalization and capex re-allocation allows focus on core operating areas FST has proven "acquire & exploit" talent Corporate transactions are harder to execute but are attractively valued INCREASES SHAREHOLDER VALUE SHARPENS OPERATIONAL FOCUS AND STRENGTHENS GROWTH POSITIVE FINANCIAL IMPACT DELIVERS ON OUR ACQUISITION STRATEGY

Cautionary Statements The United States Securities and Exchange Commission permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use the terms "probable" and "possible" reserves, reserve "potential" or "upside" or other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC's guidelines strictly prohibit Forest from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being actually realized by us. Investors are urged to consider closely the disclosure in Forest's Form 10-K for fiscal year ended December 31, 2005, available from Forest at 707 17th Street, Suite 3600, Denver, CO 80202, Attention: Investor Relations. You can also obtain this form from the SEC by calling 1-800-SEC-0330. This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, that address activities that Forest assumes, plans, expects, believes, projects, estimates or anticipates (and other similar expressions) will, should or may occur in the future are forward-looking statements. The forward-looking statements provided in this presentation are based on management's current belief, based on currently available information, as to the outcome and timing of future events. Forest cautions that its future natural gas and liquids production, revenues and expenses and other forward-looking statements are subject to all of the risks and uncertainties normally incident to the exploration for and development and production and sale of oil and gas. These risks include, but are not limited to, price volatility, inflation or lack of availability of goods and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating future oil and gas production or reserves, and other risks as described in Forest's 2005 Annual Report on Form 10-K as filed with the Securities and Exchange Commission. Also, the financial results of Forest's foreign operations are subject to currency exchange rate risks. Any of these factors could cause Forest's actual results and plans to differ materially from those in the forward-looking statements. This presentation includes "net debt", which is a non-GAAP financial measure. Please go to our website, www.forestoil.com, for a reconciliation of the non-GAAP financial measures to the most comparable GAAP financial measures.
