                         Contango Reports Third Quarter
                        Earnings and Updates Operations



    HOUSTON--(BUSINESS WIRE)--May 9, 2005--Contango Oil & Gas Company
(AMEX:MCF) reported a net loss attributable to common stock for the
three months ended March 31, 2005 of $1.2 million, or $0.09 per basic
and diluted share, compared to net income attributable to common stock
for the three months ended March 31, 2004 of $1.2 million, or $0.11
per basic and diluted share. Natural gas and oil sales from continuing
and discontinued operations for the three months ended March 31, 2005
were $1 million, down from $6.6 million for the three months ended
March 31, 2004. The decrease in revenue was primarily the result of
the sale of our south Texas natural gas and oil interests for $50
million, completed in December 2004. The $1 million of revenue for the
current quarter reflects primarily production from new reserves and
production from south Texas properties not included in the sale.
EBITDAX was $0.6 million for the three months ended March 31, 2005,
down from EBITDAX for the three months ended March 31, 2004 of $5.6
million.
    Net income attributable to common stock for the nine months ended
March 31, 2005 was $13.4 million, or $1.02 per basic and diluted
share, compared to net income attributable to common stock for the
nine months ended March 31, 2004 of $8.2 million, or $0.83 per basic
and diluted share. Natural gas and oil sales from continuing and
discontinued operations for the nine months ended March 31, 2005 were
$15.0 million, down from $20.8 million for the nine months ended March
31, 2004. EBITDAX was $27.4 million for the nine months ended March
31, 2005, up from EBITDAX for the nine months ended March 31, 2004 of
$24.0 million.
    We currently have approximately $34.8 million in cash, cash
equivalents, and short term investments and have no debt. We currently
have production of approximately 2,100 Mcf/d. Based on current prices
and production rates, the Company anticipates EBITDAX of approximately
$200,000 per month, net of estimated on-going general and
administrative expenses of $200,000 per month.
    Kenneth R. Peak, Contango's Chairman and Chief Executive Officer,
said, "As a result of the Company's increased liquidity stemming from
our recent south Texas property sale, the Company is selectively
increasing its risk exposure in certain onshore and offshore
prospects. The Company will also for the first time operate two
offshore prospects in the Gulf of Mexico through its wholly owned
subsidiary, Contango Operators, Inc. Our estimated capital budget for
exploration activities for the remainder of the calendar year 2005 is
$21 million of which $12 million will be invested in just three
prospects: our Fayetteville Shale acreage acquisition project in
Arkansas at $4 million, and two offshore exploration prospects at $4
million each. While this shift in strategy greatly increases the
potential loss to the Company from dry holes on these prospects, it
may also significantly increase our potential profit should the wells
be successful."
    Mr. Peak continued, "In the future, Contango expects to take
working interests in additional prospects generated by its two
partially owned subsidiaries, Republic Exploration and Contango
Offshore Exploration. Contango will be offered these prospects under
the same arms-length terms offered to industry participants. Some of
these working interests may involve commitments by the Company of $5
million or more per prospect."

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

A reconciliation of EBITDAX to loss from operations and operating
results for discontinued operations for the periods indicated is
presented below.
