2004 Snapshot:

     *  The company recognized record reserves and production, up 5 percent
        and 15 percent, respectively, compared with 2003.
     *  The company drilled 12 development wells in the Gulf of Mexico, of
        which 100 percent were successful.
     *  The company drilled seven exploration wells in the Gulf of Mexico, of
        which 43 percent were successful.
     *  Onshore, the company drilled 192 wells at an overall success rate of
        84 percent.
     *  The company's Rocky Mountain operations continued to grow.  During the
        year 26 wells were drilled in Utah's Uinta Basin, and in Colorado,
        more than 300,000 net acres were acquired in the Eastern DJ Basin.  At
        the present time, nearly all of the wells are producing in the Uinta
        Basin.  The four wells drilled in Colorado during the last part of
        2004 should be placed on production during the first quarter of 2005,
        along with other wells recently drilled in the area.
     *  In Arkansas, the net production rate was 65 percent greater than 2003,
        and the company continued to break monthly production records
        throughout the year.  Down-spacing approvals to 40-acres were received
        during 2004, which increased the region's reserves by 18 percent year-
     *  The company successfully improved its drilling portfolio after
        purchasing 81 Bcfe of reserves and divesting of 63 Bcfe.
     *  The company improved the liquidity of Houston Exploration stock after
        successfully completing two transactions with KeySpan Corporation
        whereby KeySpan sold its entire position in Houston Exploration stock.
     *  The company continued to conservatively manage its balance sheet,
        closing the year with a debt-to-capitalization ratio of 32 percent.

"I am very pleased that during 2004 the company was able to execute its long-term plan, which included a mix of drilling and third-party transactions in order to achieve yet another year of record reserves and production," stated William G. Hargett, chairman, president and chief executive officer.

"In addition, after closing the transactions with KeySpan, I hope that additional growth opportunities will be available to the company, as our balance sheet is in excellent condition and our borrowing base has been expanded."

Fourth Quarter 2004 Summary:
On January 20, 2005, the company announced preliminary results for several key metrics for the fourth quarter of 2004, which included explanations for any variances from previous quarters or guidance that had been provided. Actual numbers and statements recapping the results are explained in the following paragraphs.

During the fourth quarter of 2004 the company reported net income of $34.8 million, or $1.21 per fully diluted share. This compares with $25.7 million, or $0.82 per fully diluted share in the fourth quarter of 2003. Cash from operations before changes in operating assets and liabilities (a non-GAAP measure) totaled $125.9 million for the fourth quarter of 2004 versus $92.7 million during the similar period of 2003.

Fourth quarter 2004 production averaged 329 MMcfe/d, up 5 percent over 2003's fourth quarter average rate of 312 MMcfe/d. Production was down from what was anticipated primarily due to mechanical problems at the High Island 115 field, where the company lost 9 MMcfe/d for the quarter, and due to delays in receiving the right-of-way approvals necessary to begin producing wells in the Uinta Basin.

The company's fourth quarter 2004 depreciation, depletion and amortization, including asset retirement accretion, was $2.35 per Mcfe, which was $0.16 per Mcfe higher than anticipated, mainly due to higher future development costs related to Gulf of Mexico assets purchased during the fourth quarter of 2004, and the number of undeveloped reserves booked in the Rocky Mountain region during 2004.

Net general and administrative expenses for the quarter were $0.38 per Mcfe, approximately $0.19 per Mcfe higher than the company's prior guidance. Substantially all of this increase related to senior executive organizational changes made within the company during the fourth quarter that resulted in severance expenses totaling $5.1 million for the three executives whose reporting structures were affected.

As with past quarters, Houston Exploration has prepared the following table to assist with understanding the company's estimated financial results and near-term performance based on current expectations.
