UGI'S AMERIGAS UNIT TO ACQUIRE NISOURCE INC.'S COLUMBIA PROPANE,
CREATES LARGEST RETAIL MARKETER

VALLEY FORGE, Pa., January 31 --UGI Corp. (NYSE: UGI), announced that its
propane operating unit, AmeriGas Partners, L. P. (NYSE: APU), has signed a
definitive agreement to acquire the retail propane distribution businesses of
Columbia Energy Group, a NiSource Company (NYSE: NI), for approximately $208
million. The combination will create the nation's largest retail propane
marketer, distributing more than one billion retail gallons from over 700
locations. The Columbia businesses currently comprise the fifth largest retail
marketer in the country, selling over 307 million gallons annually from 186
locations in 29 states.

Lon R. Greenberg, chairman of UGI said, "We are excited about the opportunities
the acquisition of Columbia Propane presents. For many years, one of our
strategic goals has been to grow through the acquisition of both small and large
propane marketers. Given our track record of successfully integrating large
distributors, we are confident that we will be able to achieve our financial
goals for this acquisition."

"We expect the financial results of Columbia to be accretive to earnings in the
first full fiscal year of our ownership," continued Greenberg. He said the
purchase, including transaction costs, would be financed with approximately $163
million of debt and approximately $53 million of AmeriGas partnership common
units to be issued to Columbia Energy.

Eugene V. N. Bissell, chief executive officer of AmeriGas, said, "The Columbia
operations will add density to our existing business and, at the same time,
provide us with opportunities to penetrate new markets. We are pleased to have
capitalized on this opportunity to add significantly to our nationwide platform
for growth. Columbia also complements our extensive logistical network."

"We believe this transaction will not only enhance our ability to serve
customers, but also present additional opportunities for the employees of both
companies," added Bissell. "The Columbia employees are well respected in the
industry and we look forward to welcoming the over 1,600 people of Columbia into
the AmeriGas family. We have created a detailed plan to integrate the Columbia
operations with AmeriGas with minimal disruption to the workforce," concluded
Bissell.

In May 2000, Columbia Energy Group announced its intention to exit the propane
distribution business because it was not consistent with its long term strategy.
Subsequent to the announcement, Columbia Energy was acquired by NiSource in
November 2000. The transaction is subject to customary conditions, including
regulatory approval, and is expected to close in February.

UGI is a holding company with propane marketing, utility and energy marketing
subsidiaries. Through subsidiaries, UGI owns 55% of AmeriGas Partners, L. P.
(NYSE: APU), one of the nation's largest retail propane marketers.
