Total revenues for the year ended June 30, 2003, after reflecting a loss of $5.7 million from hedging activities, were $28.2 million. Total revenues for the year ended June 30, 2002, after reflecting a gain of $5.0 million from hedging activities, were $28.9 million. EBITDAX for the year ended June 30, 2003 was $20.9 million, compared with $22.5 million for the year ended June 30, 2002. For the three months ended June 30, 2003, Contango had net income of $1.2 million, or $0.13 per basic share and $0.11 per diluted share. Total revenues for the three months ended June 30, 2003, after reflecting a loss of $292,000 from hedging activities, were $8.8 million. EBITDAX for the three months ended June 30, 2003 was $7.1 million. Total proved reserves as of June 30, 2003 were 21.2 billion cubic feet of natural gas and 395,000 barrels of oil. The present value of estimated future cash flows before income taxes as of June 30, 2003, using prices of $5.23 per MMbtu of natural gas and $30.19 per barrel of oil and discounted at 10% per annum, was $69.6 million. Proved producing reserves represented 97% of total proved reserves. Operations Update Contango also announced that on September 12, 2003 it completed the sale of some non-core reserves in Brooks County, Texas for $5.0 million. Proved reserves were 1.5 Bcfe and accounted for $5.0 million of the Company's discounted present value at 10% per annum as of June 30, 2003. After the sale of these properties, the Company has $12.3 million of debt outstanding and $11.4 million of unused bank borrowing capacity. Our current production rate following the sale of these properties is 16,000 MMbtue per day. At today's commodity prices, the Company expects EBITDAX of $1.5 to $2.0 million per month through year-end 2003. Kenneth R. Peak, Chairman and Chief Executive Officer, said, "The increase in liquidity from this reserve sale comes at an opportune time. We now have eight wells, five onshore and three offshore, scheduled to begin drilling between now and year-end 2003. This is, by far, the highest activity level in the Company's history." "On our STEP properties, we will spud a Queen City development well in September. We recently completed a 3-D seismic shoot in Jim Hogg and Starr Counties, Texas and will drill an exploratory Queen City well on this acreage in October 2003. If this play develops, we would expect to drill another five to seven wells with drilling expenditures in the $3.0 to $4.0 million range. We also have a shallow oil exploratory prospect that we will drill in October. If this well is successful, it could lead to another three to five wells." "Our 3-D seismic shoot with Alta Resources in Duval County, Texas is on schedule, and we expect to have our field work completed by November 1, 2003. If the shoot is successful, we could be drilling prospects by year-end. We are also going to participate with Alta Resources in the drilling of a Queen City exploratory well in Jim Hogg County. Drilling is expected to start in October 2003. If this play develops, we would expect to drill another five to seven wells with drilling expenditures in the $3.0 to $4.0 million range. Separately, we currently are participating with a 7.1% working interest in a 15,500 foot Wilcox test in Goliad County, Texas." Commenting on offshore activities, Mr. Peak said, "Contango, Republic Exploration and Magnolia Offshore Exploration have farmed out three "deep shelf" lease blocks. Magnolia's lease block is currently drilling, and the other two farmout wells are expected to spud by year-end 2003. Contango and its partially owned subsidiaries are fully carried on all drilling and completion costs on these prospects." Contango is a Houston-based, independent natural gas and oil company. The Company explores, develops, produces and acquires natural gas and oil properties primarily onshore in the Gulf Coast and offshore in the Gulf of Mexico. Contango also owns a 10% partnership interest in a proposed LNG terminal in Freeport, Texas. Additional information can be found on our web page at www.mcfx.biz.

We have reported EBITDAX because we believe EBITDAX is a measure commonly reported and widely used by investors as an indicator of a company's operating performance and ability to incur and service debt. We believe EBITDAX assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion and amortization, impairment of natural gas and oil properties and exploration expenses, which can vary significantly depending upon accounting methods. EBITDAX is not a calculation based on the U.S. generally accepted accounting principles and should not be considered an alternative to net income (loss) in measuring our performance or used as an exclusive measure of cash flow because it does not consider the impact of working capital growth, capital expenditures, debt principal reductions and other sources and uses of cash, which are disclosed in our statements of cash flows. Investors should carefully consider the specific items included in our computation of EBITDAX. While we have disclosed our EBITDAX to permit a more complete comparative analysis of our operating performance and debt servicing ability relative to other companies, investors should be cautioned that EBITDAX as reported by us may not be comparable in all instances to EBITDAX as reported by other companies. EBITDAX amounts may not be fully available for management's discretionary use, due to requirements to conserve funds for capital expenditures, debt service, preferred stock dividends and other commitments.
