       Atmos Energy Corporation to Acquire Mississippi Valley Gas Company

Dallas (September 24, 2001)--Atmos Energy Corporation (NYSE: ATO) said today it
has signed a definitive agreement to acquire Mississippi Valley Gas Company, a
privately held natural gas utility, for $150 million. The consideration is
composed of $75 million cash and $75 million of Atmos common stock. Atmos also
will assume Mississippi Valley Gas' outstanding debt, net of working capital, of
approximately $45 million.

Atmos said the transaction will be accounted for as a purchase and expects it to
be accretive to earnings in the first full year of operation, excluding any one-
time charges related to the transaction. The acquisition is subject to approval
by the Mississippi Public Service Commission and compliance with the Hart-Scott-
Rodino Act. The issuance of Atmos common stock is subject to approval by utility
regulatory commissions in Colorado, Georgia, Illinois, Kentucky and Virginia.
The transaction is expected to be completed within a year.

Mississippi Valley Gas, based in Jackson, Mississippi, is the state's largest
gas utility. It serves approximately 261,500 Mississippi customers in 144
communities throughout 36 counties. Residential customers account for 89 percent
of the utility's customer base and for 46 percent of its revenues. Jackson is
the largest urban area served, with about 30 percent of the utility's customers
located there. The utility's fastest-growing community is Southaven, a suburb of
Memphis, Tennessee.

Mississippi Valley Gas operates a 5,500-mile distribution system and 335 miles
of transmission pipeline. The utility owns two underground gas storage
facilities at Amory and Goodwin in northeast Mississippi, with a combined
working gas capacity of 2.05 billion cubic feet.

Rates of Mississippi Valley Gas are weather-normalized and include provisions
for monthly purchased gas cost adjustments and semi-annual rate adjustments.
This rate structure is designed to mitigate the effects of weather, provide
predictable and stable earnings and cash flow and reward the utility for
excellent customer service.

"Mississippi Valley Gas will fit well into the growing Atmos system," said
Robert W. Best, chairman, president and chief executive officer of Atmos Energy
Corporation. "By expanding into Mississippi, Atmos will enhance its position in
the Southeastern United States and will gain the advantages of a strong
operating utility, additional gas-storage facilities and the goodwill from
Mississippi Valley Gas' reputation for providing excellent customer service.



"Mississippi Valley Gas will operate as a separate Atmos business unit
headquartered in Jackson," said Best. "As part of Atmos, Mississippi Valley Gas
will continue to provide its customers with the same reliable energy supplies
and high-quality service they have come to expect. Mississippi Valley Gas will
benefit from greater economies of scale and advanced technologies to keep its
operating costs low. The company also will gain more resources for maintaining
and expanding its system to serve the Mississippi economy."

Best noted that Atmos' operating divisions already serve hundreds of communities
in the nearby states of Louisiana, Tennessee, Kentucky and Georgia. In July,
Atmos completed its acquisition of the assets of Louisiana Gas Service Company
and LGS Natural Gas Company and combined them with its existing Trans Louisiana
Gas operations to form Atmos Energy Louisiana. Atmos is the largest pure gas
distributor in Louisiana and the fifth-largest in the U.S. The addition of
Mississippi Valley Gas will make Atmos the country's third-largest pure gas
distributor.

"As a result of successfully acquiring companies like Mississippi Valley Gas,"
Best said, "Atmos has more than doubled in size during the past four years. We
are proud of our record of not only adding profitable assets to our utility
system, but also maintaining our customers' trust and satisfaction."
