Legacy Reserves LP Acquisition and Commodity Swap Update

MIDLAND, Texas, Jan. 15, 2008 (PRIME NEWSWIRE) -- Legacy Reserves LP
(Nasdaq:LGCY) today announced it has pending acquisitions of $29.5 million of
producing oil and natural gas properties and has closed $2.7 million of
acquisitions during December 2007 and January 2008. All of the acquisitions are
in the Permian Basin and Texas Panhandle. The pending acquisitions are expected
to close in January 2008. The closed and pending acquisitions have aggregate net
production of 366 Boe/d, of which 68% are oil and natural gas liquids. These
acquisitions have proved reserves of approximately 2.0 million Boe's, of which
99% are classified as proved developed producing. The proved reserves to
production ratio is an estimated 14.8 years.

Cary Brown, Chairman and Chief Executive Officer, commented, "The new properties
have numerous developmental drilling locations that will be evaluated for future
drilling. These reserves represent additional interests in properties that
Legacy acquired in late 2007. Thus, we expect that there will be no incremental
administrative burden to manage these properties, and the impact of any drilling
or production enhancement will have a greater impact on Legacy's bottom line."

Including the pending acquisitions described above, Legacy has acquired or
agreed to acquire over $225 million of proved oil and natural gas properties
since our IPO on January 12, 2007 through more than 17 transactions.

Related to the announced acquisitions, Legacy today entered into NYMEX WTI oil
swaps and natural gas swaps. New WTI oil fixed price swaps are tabulated below.
WTI swaps are used to mitigate risks associated with both oil and natural gas
liquids sales as the price of natural gas liquids is highly correlated to that
of WTI oil prices.

Swaps are tabulated below for new natural gas fixed price swaps indexed to the
ANR-OK index in the Mid-continent. ANR-OK trades at a discount to the NYMEX
Henry Hub natural gas index. The natural gas prices that we receive for our
natural gas sales in the Texas Panhandle follow ANR-OK more closely than the
NYMEX Henry Hub index.
