MID-YEAR RESERVE REPORT In connection with the proposed merger with Belco Oil & Gas Corp., the Company updated its reserve forecast to June 30, 2001. As of June 30, 2001 Westport reported 444.6 Bcfe of proved reserves compared to 454.3 Bcfe as of December 31, 2000. During the six month period the Company added 38.4 Bcfe of reserves due to positive revisions relating to property performance, exploitation activities, discoveries and extensions, produced 32.2 Bcfe and had negative revisions of 15.9 Bcfe due primarily to the decline in natural gas prices from approximately $9.50 per Mcf at December 31, 2000 to $3.22 per Mcf at June 30, 2001. SECOND QUARTER OPERATIONAL HIGHLIGHTS AND OUTLOOK ONSHORE Through the end of the second quarter of 2001 the Company participated in the drilling of four horizontal wells in the South Fryburg Area of the Williston Basin, in which Westport's working interest averages 50%. Production from these wells is averaging approximately 200 Bbls of oil per day per well. Westport is currently drilling an additional horizontal well in the field and plans to participate in five or six additional horizontal wells during the second half of 2001. Westport is also planning to drill a vertical Tyler formation well in September. During the second quarter of 2001 Westport continued its successful horizontal drilling program in the Wiley Field of North Dakota, in which Westport holds a 54% working interest. Seven horizontal wells were drilled in the second quarter resulting in an increase in production of 900 Bbls of oil per day. Westport plans to drill an additional ten horizontal wells in the Wiley Field during the second half of 2001. OFFSHORE At East Cameron Block 104 production commenced in June at initial rates of 9 Mmcf/d gross. Westport owns a 60% working interest and is operator. Production on West Cameron Block 370 commenced in May at the initial rate of 33 Mmcf/d gross. Westport owns a 60% working interest and is operator. During the second quarter the Company drilled a second well in East Cameron Block 369 with an estimated 149 net feet of pay. A platform is expected to be set later this year and production is scheduled to commence within the first half of 2002. Westport owns a 60% working interest and is operator. 4 Production began from the Eugene Island 45 #1 well in June at an initial rate of 4.5 Mmcf/d gross. A third well drilled on this block in the second quarter encountered 49 net feet of pay. Production from this well is expected to commence in the second half of 2001 at similar rates as the #1 well. The Mississippi Canyon Block 322 #2 well was drilled in the second quarter by Walter Oil and Gas with an estimated 50 net feet of pay. A second well was also drilled which encountered 36 net feet of pay. Both wells have been completed and production is expected to commence in the first half of 2002. Westport owns a 25% working interest. Westport drilled two dry holes in the second quarter, one on Vermilion Block 236 at a net cost of $2.83MM and one on East Cameron Block 348 at a net cost of $2.28MM. Westport plans a high level of Gulf of Mexico exploration activity in the second half of 2001, with rigs moving in to the following prospects: <Table> <Caption> Estimated Range of Westport Working Gross Unrisked Lease Block Interest % Reserves (BCFE) Status ----------- ---------------- ------------------ ------------- HI 197 25 40-50 Drilling WD 143 50 75-85 Drilling WC 198 A-5 52.5 40-50 Drilling HI 84/85 52 25-35 Drilling ST 316 50 50-60 To be drilled MC 489 30 60-70 To be drilled </Table> MANAGEMENT COMMENT ON THE PROPOSED MERGER WITH BELCO "We continue to be excited about our proposed merger with Belco", Donald D. Wolf, CEO and Chairman, said. "We anticipate a number of benefits as a result of the combination. The expanded asset base and operational presence in our core operating areas should allow us to operate more efficiently and compete more aggressively for business opportunities in those areas. We expect to benefit from greater economies of scale to reduce our costs. Our balance sheet, combined with Belco's, should give us greater financial flexibility and lower our cost of capital. The expansion of the public float in our common stock will improve market liquidity for shareholders and should improve our access to capital through the public equity markets." On August 1, 2001 Belco filed a registration statement and joint proxy statement with the Securities and Exchange Commission dated July 31, 2001, which describes the proposed transaction. Each Company has scheduled a shareholder meeting to vote on the merger on August 21, 2001. If approved by the shareholders of each company, the merger is expected to close on August 21, 2001. The Company estimates that for the full year 2001 on a combined basis Westport and Belco would have oil and gas production of approximately 125 to 135 Bcfe and EBITDAX of $330 million to $340 million, assuming average NYMEX oil and gas prices of approximately $27.00 per barrel of oil and $4.90 per Mcf of gas. Westport expects the combined level of full year 2001 capital expenditures to be approximately $260 million. 5 CONFERENCE CALL The Company will host a conference call on Monday, August 13, 2001, beginning at 11:00 a.m. EDT, 9:00 a.m. MDT to discuss these results.

FORWARD - LOOKING STATEMENTS The statements in this report regarding estimated reserves, projected capital expenditures and financial results, expected drilling and development activity, reserves exposure, and anticipated merger benefits and impacts, and any other forecasts, projections or guidance that are not statements of historical fact, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements are inherently uncertain, and actual results may differ materially from those estimated or projected. Factors that can affect the Company's ability to achieve projected results are described in the Company's filings with the Securities and Exchange Commission, including without limitation in the Company's 10-K report filed with the SEC on March 16, 2001, and the Company's 10-Q reports for the first and second quarters of 2001 filed with the SEC on May 9 and August 14, 2001, and the registration statement and joint proxy statement dated July 31, 2001 and filed with the SEC on August 1, 2001 by Belco Oil & Gas Corp. These factors include, among others, the uncertainties inherent in reserve estimations especially for estimates of non-proved reserves and for unrisked estimates on undrilled blocks, operational risks inherent in drilling operations, especially in the offshore environment, with corresponding exposure to delays and significant cost overruns, the highly competitive nature of activity in the oil and gas industry with corresponding shortages of equipment and personnel, the risk of exploratory drilling, the uncertain cost and pricing environment in the oil and gas industry, the Company's inability to control operations on properties it does not operate, availability of capital, regulatory requirements, and uncertainties related to integrating Westport and Belco. The Company has no obligation to update the statements contained in this report or to take action that is described herein or otherwise presently planned. 6 WESTPORT RESOURCES CORPORATION CONSOLIDATED BALANCE SHEETS (IN THOUSANDS, EXCEPT SHARE DATA) <Table> <Caption> JUNE 30, DECEMBER 31, 2001 2000 ------------ ------------ (unaudited) ASSETS Current Assets: Cash and cash equivalents .................................................. $ 81,727 $ 20,154 Accounts receivable, net ................................................... 32,249 49,200 Derivative asset ........................................................... 7,401 -- Prepaid expenses ........................................................... 4,235 4,670 ------------ ------------ Total current assets ................................................... 125,612 74,024 ------------ ------------ Property and equipment, at cost: Oil and natural gas properties, successful efforts method: Proved properties ........................................................ 654,002 591,367 Unproved properties ...................................................... 42,288 40,653 Office furniture and equipment ............................................. 2,945 2,642 Leasehold improvements ..................................................... 501 501 ------------ ------------ 699,736 635,163 Less accumulated depletion, depreciation and amortization ......................
