Key Transaction Terms 655 Bcfe estimated proved reserves, 65% PD, 97% gas 2006 production of 204 MMcfe/d, 96% gas Oil and Gas Assets Forest Oil Board and Management Management and Governance 2Q 2007 Expected Close Consideration Paid $1.6 billion transaction 23.8 million shares, $739 million cash, assume $100 million net debt Structure Tax free merger Consideration election and equalization

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 INCREASES SHAREHOLDER VALUE SHARPENS OPERATIONAL FOCUS AND STRENGTHENS GROWTH 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 POSITIVE FINANCIAL IMPACT 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 DELIVERS ON OUR ACQUISITION STRATEGY FST has proven “acquire & exploit” talent Corporate transactions are harder to execute but are attractively valued

Plan For These Assets - 4 Point Strategy GROW ORGANICALLY Increase drilling activity in E. Texas and Niobrara shallow gas plays Capitalize on exposure to horizontal drilling in S. Texas and E. Texas Initiate gas liquids processing to enhance recoveries IDENTIFY ATTRACTIVE ACQUISITION OPPORTUNITIES REDUCE COSTS Apply project FOCUS to keep LOE flat Reduce G&A Lower product gathering and transportation costs PRESERVE FINANCIAL AND PERSONNEL FLEXIBILITY Decrease annual capex spending by about $200 million and focus on high-return projects Transform into a free-cash flow generator Maintain THX Houston office for business unit and support services Look to acquire additional interests in and around core areas of the asset base Use size and scale of S. Texas and E. Texas position to consolidate smaller players

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, 2006, 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 reports that Forest files with the Securities and Exchange Commission (SEC), including its 2006 Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K. 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.

Cautionary Statements (cont.) These materials are not a substitute for the registration statement that was filed with the SEC in connection with Forest’s proposed acquisition of Houston Exploration, or the joint proxy statement/prospectus that was mailed to shareholders on or about May 4, 2007. Investors are urged to read the joint proxy statement/prospectus as it contains important information, including detailed risk factors. The registration statement and other documents filed by Forest and Houston Exploration with the SEC are available free of charge at the SEC's website, www.sec.gov , or by directing a request when such a filing is made, to Forest Oil Corporation, 707 17th Street, Suite 3600, Denver, CO 80202, Attention: Investor Relations; or by directing a request to The Houston Exploration Company, 1100 Louisiana Street, Suite 2000 Houston, TX 77002, Attention: Investor Relations. This news release does not constitute an offer to sell or a solicitation of an offer to buy any shares of Forest or Houston Exploration common. Forest, its directors, executive officers and certain members of management and employees, may be considered “participants in the solicitation” of proxies from Forest’s shareholders in connection with the Houston Exploration acquisition. Information regarding such persons and a description of their interest in the acquisition is contained in the joint proxy statement/prospectus. THX, its directors, executive officers and certain members of management and employees may be considered “participants in the solicitation” of proxies from THX’s stockholders in connection with the acquisition. Information regarding such persons and a description of their interest in the acquisition is contained in the joint proxy statement/prospectus.
