         Contango Reports Third Quarter Earnings and Updates Operations


    HOUSTON--(BUSINESS WIRE)--May 15, 2006--Contango Oil & Gas Company
(AMEX:MCF) reported net income attributable to common stock for the
three months ended March 31, 2006 of $0.7 million, or $0.05 per basic
and diluted share, compared to 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. The increase was attributable to an
increase in crude oil and natural gas prices and an increase in our
oil production.
    Net income attributable to common stock for the nine months ended
March 31, 2006 was $0.4 million, or $0.03 per basic and diluted share,
compared to net income attributable to common stock for the nine
months ended March 31, 2005 of $13.4 million, or $1.02 per basic and
diluted share, which included a gain on the sale of discontinued
operations of $16.3 million, from the sale of our south Texas natural
gas and oil interests that was completed in December 2004.
    EBITDAX for the three months ended March 31, 2006 was $2.1 million
compared to $0.6 million for the three months ended March 31, 2005.
EBITDAX for the nine months ended March 31, 2006 was $4.2 million
compared to $27.4 million for the nine months ended March 31, 2005.
    Kenneth R. Peak, Contango's Chairman and Chief Executive Officer,
said, "We expect to begin drilling our High Island A-279 ("Juice") and
our West Delta 43 ("Skip Jack") prospects in June, and our Eugene
Island 10 ("Dutch") prospect in July.
    "In our Arkansas Fayetteville Shale Play, we and our operating
group have acquired or received commitments on approximately 42,000
net mineral acres. The Arkansas Oil & Gas Commission has now approved
eleven of our 640-acre drilling units, which we estimate will allow
our operating group to drill and operate approximately 100 horizontal
wells. In addition, we have now been integrated into 35 wells that are
being operated by a third party oil and gas exploration company, seven
of which are producing. The remaining 28 horizontal wells are either
being drilled or are expected to be drilled over the next three
months. We recently logged 240 feet of net Fayetteville Shale in our
first Alta operated well, the Alta Beck #1-32H, and are currently
drilling this well horizontally.
    "On March 15, 2006, two affiliated companies were the apparent
high bidders on a total of 16 lease blocks at the Central Gulf of
Mexico Lease Sale #198. We were recently awarded our 11th lease block
from this sale, West Delta 77, bringing the total number of lease
blocks Contango and its affiliates have to 62 offshore leases.
    "As of May 11, 2006, we have approximately $33 million in cash,
cash equivalents, and short term investments. In addition, the Company
has $10.0 million of unutilized borrowing capacity. Our principal
focus will continue to be our deep shelf Gulf of Mexico and
Fayetteville Shale exploration programs."

(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 continuing operations and
operating results for discontinued operations for the periods
indicated is presented below.
