             PIPELINE OPERATIONS, TPC CORP.; MCGILL TO CONTINUE
            AS PRESIDENT OF HOUSTON'S COLUMBIA GULF TRANSMISSION

        MERRILLVILLE, Ind. (August 22, 2000) - NiSource Inc. has
   appointed several key leaders to be in place at its natural gas
   pipeline units and at TPC Corporation upon completion of its $6
   billion merger with Columbia Energy Group, which was announced Feb. 28
   and is expected to close by year-end.

        JAMES K. ABCOUWER, currently a senior vice president of NiSource
   and president and chief executive officer of NiSource's EnergyUSA,
   Inc. subsidiary, will become president of Houston-based TPC
   Corporation, a natural gas marketer and gas asset portfolio manager
   for utilities.

        TERRANCE L. MCGILL will continue in the role of president of
   Columbia Gulf Transmission Co., the Houston-based pipeline unit.
   McGill, who has been president of Columbia Gulf since 1996, has more
   than 20 years of diversified experience in the natural gas industry
   with a particular emphasis on interstate transportation and contract
   negotiations.

        W. HARRIS MARPLE, currently senior vice president for Field
   Services for Columbia's pipeline operations will continue in that role
   as senior vice president of operations for both Columbia Gas
   Transmission and Columbia Gulf Transmission, as well as for NiSource's





   Crossroads Pipeline Company and NiSource's investment in Portland
   Natural Gas Transmission System. Marple will be based in Charleston,
   W.Va., with responsibility for operations, engineering and technical
   support of a 17,000-mile interstate natural gas pipeline system
   stretching from the Gulf of Mexico to the U.S. Midwest and Northeast.

        The company also announced that GLEN L. KETTERING, senior vice
   president for Customer Services at Columbia Gas Transmission Corp.,
   has been named president of the natural gas pipeline unit.  A
   Charleston native, Kettering will be based at the company's Fair
   Lakes, Va., office.

        All three of the pipeline officers will report to CATHERINE G.
   ABBOTT, who will become president of Pipeline Operations when the
   merger is completed.  Her appointment was announced Aug. 1.

        "Columbia's pipeline operations and NiSource's TPC are important
   elements in NiSource's strategy to serve the energy-intensive
   geographic corridor stretching from the Gulf Coast through Chicago to
   New England.  We intend to continue the long and successful
   partnership that the Columbia and NiSource companies have had with the
   states in which we will have operations," said Gary L. Neale, NiSource
   chairman, president and chief executive officer.

        Once the merger is completed, NiSource will serve more than 3.6
   million gas and electric customers primarily located in nine states.
   Its operations will span the high-growth energy corridor extending
   from the Gulf of Mexico through Chicago to New England, creating the
   largest natural gas distributor east of the Rockies, with wholesale
   and retail electric operations.

        The NiSource/Columbia merger is on target to close by the end of
   2000, pending approval by the U.S. Securities and Exchange Commission.
   The combination was approved by the Federal Energy Regulatory
   Commission in July, following necessary state actions regarding the
   companies' distribution companies in Virginia, Pennsylvania, Maryland,
   Indiana, Kentucky, Massachusetts, Ohio, Maine and New Hampshire.  The
   transaction also recently cleared the waiting period under the Hart-
   Scott-Rodino Antitrust Improvements Act at the U.S. Department of
   Justice and the Federal Trade Commission.  Shareholders of both
   companies approved the merger in June.
