October 1, 2008, the Company completed it previously announced acquisition of
oil and natural gas properties in the Barnett Shale from Hollis R. Sullivan,
Inc. and other interest owners for an aggregate purchase price of approximately
$800 million. These properties are located in Johnson, Tarrant, Parker, Wise,
Hood, Hill, Ellis and Bosque counties of Texas. The Company&#8217;s internal engineers
estimate the proved reserves to be in excess of 300 billion cubic feet of
natural gas equivalent, 25% of which are proved developed reserves. The
acquisition is expected to initially add production of 35 million cubic feet of
natural gas equivalent per day and will add 12,900 net acres in the Barnett
Shale adjacent to the Company&#8217;s existing operations.</font></div>

Item
8.01.  Other Events
On
October 1, 2008, the Company completed it previously announced acquisition of
oil and natural gas properties in the Barnett Shale from Hollis R. Sullivan,
Inc. and other interest owners for an aggregate purchase price of approximately
$800 million. These properties are located in Johnson, Tarrant, Parker, Wise,
Hood, Hill, Ellis and Bosque counties of Texas. The Company's internal engineers
estimate the proved reserves to be in excess of 300 billion cubic feet of
natural gas equivalent, 25% of which are proved developed reserves. The
acquisition is expected to initially add production of 35 million cubic feet of
natural gas equivalent per day and will add 12,900 net acres in the Barnett
Shale adjacent to the Company's existing operations.
The
foregoing description of the acquisition is qualified in its entirety by
reference to the Purchase and Sale Agreement attached as Exhibit 2.1 to Form 8-K
filed by the Company on July 24, 2008.
Forward-Looking
Statement and Related Matters
Statements
made in this Form 8-K, including those relating to proved reserves
and  growth in daily production  are forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. These statements are based
on assumptions and estimates that management believes are reasonable based on
currently available information; however, management's assumptions and the
Company's future performance are both subject to a wide range of business risks
and uncertainties and there is no assurance that these goals and projections can
or will be met. Any number of factors could cause actual results to differ
materially from those in the forward-looking statements, including, but not
limited to, changes in oil and gas prices, changes in underlying demand for oil
and gas, the timing and results of drilling activity, higher than expected
production costs and other expenses and general market
conditions.  The Company undertakes no obligation to publicly update
or revise any forward-looking statements. Further information on risks and
uncertainties is available in the Company's filings with the Securities and
Exchange Commission, which are incorporated by this reference as though fully
set forth herein.
Reserve
estimates with respect to the acquisition were made by our internal engineers
without review by an independent petroleum engineering firm. Data used to make
these estimates were furnished by the sellers and may not be as complete as that
which is available for our owned properties. We believe our estimates of proved
reserves comply with criteria provided under rules of the Securities and
Exchange Commission.
