OHIO COMMISSION SUPPORTS NISOURCE/COLUMBIA ENERGY GROUP MERGER

         MERRILLVILLE, Ind. and HERNDON, Va. (May 2, 2000) -- NiSource Inc. and
Columbia Energy Group announced that the Public Utilities Commission of Ohio
(PUCO) today authorized a letter to the U.S. Securities and Exchange Commission
(SEC) stating that the NiSource/Columbia Energy Group merger would have no
impact on its ability to protect the interests of Columbia Gas of Ohio
ratepayers.

         The PUCO letter also said it would continue to exercise jurisdiction
over the regulated activities of Columbia Gas of Ohio, a natural gas
distribution subsidiary of Columbia Energy Group, following the companies'
proposed merger.

         Today's decision moves the NiSource/Columbia merger a step closer to
the expected completion of the transaction later this year. The commission's
staff and Columbia Gas of Ohio regulatory staff negotiated a number of
commitments by the utility, Columbia Energy Group and NiSource, which furnished
the basis of the commission action. Columbia Gas of Ohio is the largest natural
gas utility in the state with more than 1.3 million customers in 64 of Ohio's 88
counties. Still pending are actions by several state public utility commissions
and federal agencies, as well as shareholder votes on the merger.

         "We appreciate the Ohio commission's timely action and consideration in
addressing the merger," said Gary L. Neale, NiSource chairman, president and CEO
and Oliver G. Richard III, Columbia Energy Group chairman, president and CEO, in
a joint statement. "Consumer service and value delivery have and will continue
to be major goals of the Columbia Gas distribution business."

         "Columbia Energy Group and NiSource are proud of the record of
excellence in customer service that has been established by Columbia Gas of
Ohio," the Ohio utility stated in a commitment letter submitted to the PUCO. The
letter also said the merging companies are committed to continuation of Columbia
Gas of Ohio's robust Customer Choice(SM) program and its collaborative process
in working with the Commission on evolving issues in a competitive gas market.

                            Ohio Commission Supports NiSource/Columbia Merger--2


         In the letter, Columbia Gas of Ohio, acting on its own behalf and that
of the merging companies, committed to the following:

     o    Its  headquarters  will  remain at its present  location in  Columbus,
          Ohio;

     o    The  merging  companies  do not  anticipate  any  material  impact  on
          Columbia Gas of Ohio employment levels.

     o    The PUCO and its staff  will have  access to the books and  records of
          Columbia Gas of Ohio and other  affiliates  when relevant to the rates
          and services of Columbia Gas of Ohio;

     o    The  proposed  merger  leaves in place the  Columbia  Gas of Ohio rate
          freeze  until  October  2004  that  was  negotiated   earlier  with  a
          regulatory collaborative and adopted by the PUCO.

         The NiSource/Columbia Energy Group merger, announced February 28, will
result in a combined company serving more than 4.1 million customers primarily
located in nine states. Its operations will span the high-growth energy
consumption corridor stretching from the Gulf of Mexico to New England, creating
the largest natural gas distributor east of the Rocky Mountains.
