Company (AMEX:MCF) reported a net loss for the year ended June 30,
2003 of $4.9 million, or $0.54 per basic and diluted share, compared
to net income for the year ended June 30, 2002 of $6.0 million, or
$0.55 per basic share and $0.48 per diluted share. 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

 EBITDAX (1)                                $20,900,941  $22,485,600

(1) EBITDAX represents earnings before interest, income taxes,
    depreciation, depletion and amortization, impairment expenses,
    exploration expenditures, including gain (loss) from hedging
    activities. 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.
