   this Application/Declaration on Form U-1 (File No. 70-9551) as
   follows:

   ITEM 1.   DESCRIPTION OF TRANSACTION
   ------------------------------------

   A.   INTRODUCTION AND OVERVIEW OF THE TRANSACTION
        --------------------------------------------

             CEG Acquisition Corp. ("Acquisition Corp."), a Delaware
   corporation and a wholly-owned subsidiary of NiSource Inc., an Indiana
   corporation whose principal executive offices are located at 801 East
   86th Avenue, Merrillville, Indiana 46410 ("NiSource"), and NiSource
   herein request authority pursuant to the applicable standards of the
   Public Utility Holding Company Act of 1935, as amended, 15 U.S.C.
   Section 79a, ET SEQ. ("Act"), to acquire all of the outstanding common
   stock of Columbia Energy Group ("Columbia"), par value $.01 per share,
   and, to the extent required under the Act, for the related
   transactions herein described. Subsequent to the consummation of the
   acquisition, Acquisition Corp. would consummate a merger with Columbia
   pursuant to the Delaware General Corporation Law ("DGCL").  The
   acquisition by Acquisition Corp. of the stock of Columbia and the
   subsequent merger of these companies is referred to herein as the

    "Transaction." Columbia, a Delaware corporation, is a registered
   holding company under the Act.  NiSource, currently an exempt holding
   company pursuant to Section 3(a)(1) of the Act, owns all of the issued
   and outstanding common stock of three public utility subsidiary
   companies that provide electric and retail natural gas service within
   the state of Indiana and two public utility subsidiary companies that
   provide retail natural gas service in the states of Maine,
   Massachusetts and New Hampshire.

             On June 25, 1999, Acquisition Corp. commenced a tender offer
   pursuant to the Securities Exchange Act of 1934, as amended, 15 U.S.C.
   Section 78, ET SEQ. ("1934 Act"), to purchase all of the outstanding
   shares of common stock of Columbia, at $68 per share, in cash, which
   was subsequently increased on October 17, 1999 to $74 per share, on
   the terms and subject to the conditions set forth in Acquisition
   Corp.'s  Offer to Purchase and Related Letter of Transmittal
   ("Offer").  The purpose of the Offer and the Transaction is to enable
   NiSource to acquire control of, and the entire equity interest in,
   Columbia.  The terms of the Offer comply with the provisions of Rule
   51.  The Offer is conditioned on, among other things, approval under
   the Act.  No fees are payable with respect to the Offer; no indemnity
   is provided for market or investment risk; no transfers of tendered
   shares will be made by Acquisition Corp.; and tendered shares may be
   withdrawn under the circumstances contemplated by Rule 51.  Upon
   acquisition of the shares of Columbia common stock, and after
   necessary approvals under the Act, NiSource and Acquisition Corp. will
   each register as a holding company pursuant to Section 5 of the Act.

             Pursuant to Sections 9(a)(2) and 10 of the Act, NiSource and
   Acquisition Corp. hereby request authorization and approval of the

   Securities and Exchange Commission ("Commission") (i) to acquire,
   pursuant to the Offer and the Transaction as described herein, all of
   the issued and outstanding common stock of Columbia, and indirectly,
   all of the outstanding voting securities of the direct and indirect
   subsidiaries of Columbia and (ii) for the subsequent merger of
   Acquisition Corp. and Columbia.  Approval is also requested under
   Section 13 of the Act and the rules promulgated thereunder for the
   provision of services to the resulting direct or indirect subsidiaries
   of NiSource by a service company subsidiary of NiSource.

             NiSource has sought to negotiate a merger transaction with
   Columbia.  To date, Columbia has refused to enter into negotiations
   with NiSource.  NiSource intends to continue to seek to negotiate with
   Columbia with respect to the consummation of a consensual merger
   transaction.  If such negotiations occur and result in a definitive
   merger agreement between Columbia and NiSource, certain material terms
   of the Offer may change.  Such negotiations could result in, among
   other things, termination of the Offer and submission of a different
   acquisition proposal to Columbia's stockholders for approval.
   Accordingly, the terms and details of the Transaction will depend on a
   variety of factors, legal requirements, the actions of Columbia's
   board of directors and whether the conditions stated in the Offer are
   satisfied in whole or in part.  Although certain representations made
   and approvals sought in this Application/Declaration may change if a
   negotiated merger is reached with Columbia, NiSource is making the
   filing at this time pursuant to the requirement of Rule 51 that the
   application for approval of the Transaction contemplated by the Offer
   be filed as soon as practicable.  In the absence of a cooperative
   relationship with Columbia, NiSource will require additional time to
   obtain and reflect in the Application/Declaration certain of the
   information relevant to the Transaction.  In addition, as noted,
   NiSource will continue to seek to negotiate with Columbia with respect
   to its proposed combination of the companies.  Such negotiations may
   change the terms of the proposed combination, and expedite the
   availability of information to NiSource.  Under these circumstances,
   NiSource expects to amend this Application/Declaration with additional
   relevant information as it is compiled by, or becomes available to,
   NiSource.

             The Transaction will produce benefits to the public,
   investors and consumers and will satisfy all of the applicable
   standards of the Act.  NiSource and Acquisition Corp. believe that the
   Transaction will provide important strategic and financial benefits to
   NiSource's shareholders and Columbia's shareholders, as well as to
   their respective employees and customers and the communities in which
   they provide public utility service.  Among other things, NiSource
   believes that the Transaction will provide benefits in the form of an
   enhanced ability to take advantage of future strategic opportunities
   in the increasingly competitive and rapidly evolving markets for
   energy and energy services in the United States.  Further, as
   explained more fully in ITEM 3   APPLICABLE STATUTORY PROVISIONS,
   NiSource believes that, following the Transaction, the combined

                                      2

   companies will be better positioned to take advantage of operating
   economies and efficiencies through, among other measures, joint
   management and optimization of their respective portfolios of gas
   supply, transportation and storage assets.  The combination of
   Columbia's gas utilities with NiSource's electric utility operations
   will enhance the competitive position of Columbia's gas utilities as
   the competition among various sectors of the utility/energy business
   continues to accelerate.

             Assuming a Transaction priced at $74 per share of common
   stock of Columbia, NiSource Capital Markets Inc. ("Capital Markets"),
   a wholly-owned subsidiary of NiSource, will issue notes due 364 days
   after issuance in the approximate amount of, but not to exceed, $6.5
   billion ("Tender Notes") to a consortium of banks in order to obtain
   funds necessary for the acquisition of the stock of Columbia pursuant
   to the Offer.  These notes will be refinanced with longer-term
   financing that will include the issuance of equity.  Prior to
   completion of the Transaction, NiSource will file one or more
   additional Application/Declarations under the Act with respect to the
   ongoing financing activities, non-utility businesses, other
   investments of, and other matters pertaining to, the combined company
   after giving effect to the Transaction and the registration of
   NiSource and Acquisition Corp. as holding companies.  Among the
   transactions included in such filings will be NiSource's issuance of
   common stock and other securities to refinance the Tender Notes.

        1.   Background

             In the ordinary course of its business, NiSource engages in
   the ongoing evaluation of strategic alternatives, including the
   consideration of potential candidates for acquisitions and strategic
   transactions.  NiSource identified Columbia as a potential acquisition
   that would create significant strategic benefits and opportunities for
   profitable growth in view of the regulatory and technological changes
   in the natural gas industry and the increasingly competitive
   marketplace for energy and energy services.  In discussions and
   correspondence between November 1998 and early June 1999, NiSource
   attempted to pursue a possible business combination with Columbia on a
   friendly basis.  On June 7, 1999, NiSource publicly announced its
   offer to acquire all of the outstanding common stock of Columbia for
   $68 per share, in cash.  On June 10, 1999, Columbia rejected
   NiSource's offer.  On June 25, 1999, Acquisition Corp. commenced the
   Offer.  The Offer initially expired on August 6, 1999 but was extended
   until midnight on October 15, 1999.  At that time, Columbia
   shareholders tendered 44,448,778 shares of stock pursuant to the Offer
   which represents approximately 54% of Columbia's outstanding common
   shares. On October 17, 1999, NiSource increased its offer to $74 per
   share, in cash.  The increased Offer will expire at midnight on
   November 12, 1999.



                                      3

        2.   Terms

             Upon consummation of the Offer, NiSource will acquire
   control of, and a controlling interest in, Columbia.  NiSource
   currently intends, as soon as practicable following consummation of
   the Offer, to propose and seek to have Columbia consummate a merger
   with Acquisition Corp.  The purpose of the merger under these
   circumstances would be to acquire all shares not tendered and
   purchased pursuant to the Offer or otherwise.  Pursuant to the merger,
   each then outstanding share (other than shares owned by Acquisition
   Corp., shares held in the treasury of Columbia and shares owned by
   stockholders who perfect available dissenters' rights under the DGCL)
   would be converted into the right to receive an amount in cash equal
   to the price per share paid in the Offer.

             In the event that Acquisition Corp. acquires shares which
   constitute at least 90% of the outstanding shares of Columbia's common
   stock, it will consummate a "short-form" merger pursuant to Section
   253 of the DGCL.  Section 253 of the DGCL provides that if Acquisition
   Corp. owns at least 90% of the outstanding shares, Acquisition Corp.
   may merge with Columbia without approval or any other action on the
   part of the board of directors or the stockholders of Columbia.

             One of the conditions of the Offer is there being validly
   tendered and not properly withdrawn shares of common stock of Columbia
   which, together with any shares owned by NiSource and its
   subsidiaries, represent at least 51% of the voting power of Columbia
   ("Minimum Condition").  If Acquisition Corp. purchases enough shares
   to satisfy this condition, but does not purchase a sufficient number
   of shares to effect a "short-form" merger, Acquisition Corp. would
   seek to effect a merger with Columbia pursuant to Section 251 of the
   DGCL.  Under Columbia's certificate of incorporation and the DGCL,
   approval of Columbia's board of directors and a vote of at least a
   majority of the outstanding shares entitled to vote thereon would be
   required to approve such a merger.  If the Minimum Condition is
   satisfied, Acquisition Corp. would have a sufficient number of votes
   to effect the stockholder approval of a merger pursuant to Section 251
   of the DGCL, which approval could be effected by a vote at a meeting
   of stockholders.  Approval of such a merger would nonetheless also
   require the approval of Columbia's board of directors.

             Columbia shareholders do not have appraisal rights as a
   result of the Offer.  However, if the merger is consummated,
   shareholders of Columbia at the time of the merger who do not vote in
   favor of the merger will have the right under the DGCL to dissent and
   demand appraisal of, and receive payment in cash of the fair value of,
   their shares outstanding immediately prior to the effective date of
   the merger in accordance with Section 262 of the DGCL.

             The agreements and documents to accomplish this merger of
   Acquisition Corp. and Columbia will be filed, by amendment, as
   exhibits hereto.

                                      4

             The Offer is subject to certain conditions in addition to
   the Minimum Condition.  One condition is that the restriction on
   certain business combinations contained in Section 203 of the DGCL not
   apply to NiSource or Acquisition Corp. in connection with the
   Transaction.  This restriction, which could delay the Transaction for
   a significant period of time, may be avoided if prior to the
   acceptance for payment of shares of Columbia common stock pursuant to
   the Offer (i) at least 85% of the outstanding voting stock of Columbia
   (other than shares held by directors who are also officers and certain
   employee stock plans of Columbia) are acquired by Acquisition Corp. or
   (ii) the board of directors of Columbia approves the Transaction.  The
   terms of the Offer and the conditions applicable thereto (including
   the foregoing) are described in Exhibit 11.A.1 to Acquisition Corp.'s
   Schedule 14D-1, which is attached hereto as Exhibit C-1.  See also
   ITEM 3, SECTION A.2.b for a description of the consideration offered
   in connection with this Transaction.

             Consummation of the Offer and the Transaction is also
   subject to various regulatory approvals, including approval of the
   Commission under the Act.  SEE ITEM 4   REGULATORY APPROVALS and
   Exhibit 11.A.1 of Acquisition Corp.'s Schedule 14D-1 which is attached
   hereto as Exhibit C-1.

             Upon consummation of the Transaction, NiSource would own an
   integrated gas utility system comprised of its existing gas
   distribution utilities in Indiana, Massachusetts, Maine and New
   Hampshire and, through its ownership of Acquisition Corp., Columbia's
   gas distribution utilities in Ohio, Pennsylvania, Maryland, Kentucky
   and Virginia.  In addition, NiSource would continue to own its
   existing integrated electric utility system in Indiana.  Accordingly,
   NiSource and Acquisition Corp. would each register as a holding
   company pursuant to Section 5 of the Act.  Further, NiSource would
   continue to own its interest in its existing non-utility businesses,
   as described herein, and, through Acquisition Corp., Columbia's
   existing non-utility businesses.

        3.   Financing of the Offer and Transaction

             Assuming a Transaction priced at $74 per share of common
   stock of Columbia, NiSource estimates that approximately $6.5 billion
   will be required to acquire the outstanding shares of Columbia
   pursuant to the Offer and to pay related fees and expenses.
   Acquisition Corp. will obtain the funds required to consummate the
   Offer and Transaction through advances made by Capital Markets.

             NiSource has accepted a commitment letter ("Commitment
   Letter") from Credit Suisse First Boston Corporation ("Credit Suisse
   First Boston") and Barclays Bank PLC ("Barclays" and together with
   Credit Suisse First Boston, the "Underwriters"), pursuant to which,
   subject to specified conditions, the Underwriters agree to provide
   Capital Markets a 364-day revolving credit facility from the date of
   the Commitment Letter in the amount of $6.5 billion, with an option to

                                      5

   convert outstanding loans at the expiration of such period into term
   loans maturing 364 days thereafter ("Facility") to finance the Offer
   and the Transaction.  A portion of the Facility may be provided by a
   syndicate of banks and other financial institutions arranged by the
   Underwriters.  Credit Suisse First Boston will act as administrative
   agent for the Facility, Barclays will serve as documentation agent for
   the Facility, and Credit Suisse First Boston and Barclays will act as
   lead arrangers and co-syndication agents.  The Facility will be
   entitled to the benefits of the Support Agreement (defined below)
   between NiSource and Capital Markets pursuant to which NiSource has
   agreed (i) to cause Capital Markets to maintain at all times a
   positive net worth and (ii) to provide Capital Markets with the funds
   necessary to make debt service payments with respect to the Facility.

             The proceeds of the Facility are to be used to finance the
   Offer and the Transaction, to refinance existing indebtedness and to
   pay related fees and expenses.  The proceeds of the Facility also are
   permitted to be used to support a commercial paper program used for
   these purposes.

             Upon the issuance by NiSource or any of its subsidiaries of
   any debt or equity (in each case subject to exceptions to be agreed
   upon), the Facility will be reduced by an amount equal to the net cash
   proceeds of such debt or equity financing.  Loans under the Facility
   ("Loans") must be repaid on the date of any such reduction to the
   extent the amount of outstanding Loans exceeds the amount of the
   Facility as so reduced.

             The Loans will bear interest, at Capital Markets' option, at
   specified spreads above LIBOR (adjusted for reserves) or Credit Suisse
   First Boston's Base Rate or at a negotiated competitive bid rate.
   Loans bearing interest based upon LIBOR will be for interest periods
   of one, two, three or six months.  All interest will be paid at the
   end of the applicable interest period or quarterly, whichever is
   earlier.  In addition, a utilization fee will be payable at a
   specified per annum rate on the outstanding principal amount at any
   time more than 25% of the commitment has been borrowed, and a facility
   fee will be payable at a specified per annum rate on the entire amount
   of the Facility, whether or not utilized.

             The Underwriters' commitments to provide the Facility may by
   terminated in the event of certain customary events.  The conditions
   precedent to the initial borrowing under the Facility include: (a)
   execution and delivery of satisfactory loan documentation, (b) receipt
   by Capital Markets of senior unsecured short-term debt ratings from
   Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's
   Ratings Services ("S&P") of at least A2 and P2, respectively, and
   senior unsecured long-term debt ratings from Moody's and S&P of a
   least Baa2 and BBB, respectively, (c) the Underwriters' reasonable
   satisfaction with the terms and conditions of the Offer and the
   Transaction, (d) the satisfaction of the conditions to the
   consummation of the Offer and the Transaction and (e) receipt of all

                                      6

   necessary consents and approvals to consummate the Transaction and the
   related transactions.

             The definitive documentation relating to the Facility also
   will contain representations, warranties, covenants, events of default
   and conditions customary for transactions of this type, including a
   covenant to consummate the merger of Columbia and Acquisition Corp.
   within 180 days of the consummation of the Offer.  In addition, the
   Facility will contain financial covenants requiring maintenance of a
   minimum interest coverage ratio and a maximum leverage ratio.

             NiSource will be required to pay underwriting and upfront
   fees to the Underwriters and syndication fees to the lenders in
   connection with the Facility.  Capital Markets will be required to pay
   certain expenses of, and provide customary indemnities to, the
   Underwriters and (under certain circumstances) the other lenders under
   the Facility.

             Underwriting and upfront fees to be paid in connection with
   the Facility will be specified by amendment to this
   Application/Declaration.  The credit agreement and related
   documentation for the Facility will be filed, by amendment, as Exhibit
   B-3 hereto.

             The Facility represents short-term bridge financing for the
   acquisition of Columbia.  The combined cash flow of NiSource and
   Columbia is expected to be adequate to service the interest
   requirements of the Facility without adverse effect on the current
   earnings levels of NiSource common stock.  NiSource anticipates that
   the Facility will be repaid with internally generated funds, including
   those generated by Columbia and its subsidiaries, and from the
   proceeds of the issuance by NiSource of additional equity and other
   securities.  At this time, no specific plans or arrangements have been
   made for such future issuance of securities; however, the issuance of
   such securities will be in such proportion as to result in a capital
   structure for NiSource comparable to other registered holding
   companies.  Prior to the consummation of the Transaction, NiSource
   will file a separate Application/Declaration under the Act with
   respect to the issuance of equity and other securities for the
   purposes of refinancing the Facility and with respect to its proposed
   financing activities after giving effect to the Transaction.

        4.   Resulting Management

             The successful completion of the Transaction as currently
   proposed would not affect the management of NiSource.  The management
   of Acquisition Corp. would be substantially identical with that of
   NiSource.  To the extent, however, that a negotiated merger
   transaction occurs, the management and boards of directors of NiSource
   and Acquisition Corp. would be expected to include some of the
   individuals currently serving those functions with Columbia.  The
   Application/Declaration will be amended to provide further detail as

                                      7

   to the board of directors and management of NiSource and Acquisition
   Corp.

        5.   Benefit Plans

             Information regarding the effect of the Transaction on the
   employee benefit and shareholder benefit plans of NiSource and
   Columbia will be provided by amendment.

   2,200,000.  Northern Indiana distributes gas to approximately 673,300
   residential, commercial and industrial customers and generates,
   purchases, transmits and sells electricity to approximately 421,000
   retail and wholesale electric customers.  Kokomo Gas supplies natural
   gas to approximately 34,200 retail customers in a six-county area of
   north central Indiana having a population of approximately 100,000.
   The Kokomo Gas service territory is contiguous to Northern Indiana's
   gas service territory.  NIFL supplies natural gas to approximately
   34,800 retail customers in five counties in the northeast corner of
   Indiana having a population of approximately 66,700.  The NIFL service
   territory is also contiguous to Northern Indiana's gas service
   territory and overlaps Northern Indiana's electric service territory.
   Northern Indiana has initiated a multi-phase customer choice program
   to allow residential and commercial customers the right to choose
   alternative gas suppliers.  The three Indiana operating utility
   subsidiaries of NiSource are subject to regulation by the Indiana
   Utility Regulatory Commission ("IURC") as to rates, service and other
   matters.

             Bay State provides gas service to approximately 266,570
   residential, commercial and industrial customers in three separate
   areas of Massachusetts covering approximately 1,344 square miles and
   having a combined population of approximately 1,340,000.  These
   include the greater Springfield area in western Massachusetts, an area
   southwest of Boston that includes the cities of Attleboro, Brockton
   and Taunton, and an area north of Boston extending to the New
   Hampshire border that includes the city of Lawrence.  Bay State
   initiated a multi-phase customer choice program to allow residential
   and commercial customers the right to choose alternative gas
   suppliers.  In November 1998, the Massachusetts Department of
   Telecommunications and Energy ("MDTE") issued a generic order
   implementing statewide customer choice for gas customers.  Bay State
   is complying with this order.  Bay State is subject to regulation by
   MDTE as to rates, service and other matters.

   population of approximately 450,000.  Northern's service area extends
   north from the Massachusetts-New Hampshire border to the
   Portland/Lewiston area in Maine.  Northern is subject to regulation by
   the New Hampshire Public Utilities Commission and the Maine Public
   Utilities Commission as to rates, service and other matters.  At this
   time, Northern remains an indirect subsidiary of NiSource, through Bay
   State, pending consummation of the Transaction and registration by
   NiSource, and will continue to be an indirect subsidiary of NiSource
   after the merger with Columbia.

             For the twelve months ended June 30, 1999, the gas and
   electric public utility subsidiaries of NiSource reported segment

   approximately $2.73 billion.  Results for this period included five
   months of combined operations with Bay State.  Gas sales (including
   transportation service) accounted for approximately 53% and electric
   sales accounted for approximately 47% of NiSource's gross utility
   revenues.  Consolidated assets of NiSource and its subsidiaries as of
   June 30, 1999, were approximately $6.4 billion, consisting of $4.1
   billion in net gas and electric utility plant ($1.8 gas and $2.3
   electric) and associated facilities and $2.3 billion in net
   non-utility plant and other non-utility assets.

   a support agreement ("Support Agreement") between NiSource and Capital
   Markets which provides that NiSource make payments of principal and
   interest on Capital Markets' obligations in the event of a failure to
   pay by Capital Markets.  Under the terms of the Support Agreement, in
   addition to the cash flow of cash dividends paid to NiSource by any of
   its consolidated subsidiaries, the assets of NiSource are available as
   recourse for the benefit of Capital Markets' creditors except that
   restrictions in the Support Agreement prohibit recourse on the part of
   Capital Markets' creditors against the stock and assets of Northern
   Indiana which are owned by NiSource.  The carrying value of the assets
   of NiSource, other than the assets of Northern Indiana, as reflected
   in the consolidated financial statements of NiSource, was
   approximately $2.6 billion at June 30, 1999.  The Support Agreement is

   the securities of these direct subsidiaries except for approximately
   8% of the stock in Columbia LNG Corporation.

             Columbia and its principal pipeline subsidiary, Columbia
   Transmission, emerged from bankruptcy on November 28, 1995, after
   filing separate petitions for protection under Chapter 11 of the
   Federal Bankruptcy Code ("Bankruptcy Code") on July 31, 1991.  During
   the bankruptcy period, both Columbia and Columbia Transmission were
   debtors-in-possession under the Bankruptcy Code and continued to
   operate their businesses in the normal course subject to the
   jurisdiction of the United States Bankruptcy Court for the District of
   Delaware.

             Transmission and Storage Operations:  Columbia's two
   interstate pipeline subsidiaries, Columbia Transmission and Columbia
   Gulf Transmission Company ("Columbia Gulf"), operate a 16,700-mile
   pipeline network extending from offshore in the Gulf of Mexico to Lake
   Erie, New York and the eastern seaboard.  In addition, Columbia
   Transmission operates one of the nation's largest underground natural
   gas storage systems.  Together, Columbia  Transmission and Columbia
   Gulf serve customers in fifteen northeastern, midatlantic, midwestern
   and southern states and the District of Columbia.  Columbia Gulf's
   pipeline system extends from offshore Louisiana to West Virginia and
   transports a major portion of the gas delivered by Columbia
   Transmission.  It also transports gas for third parties within the
   production areas of the Gulf Coast.  Columbia Transmission and
   Columbia Gulf provide an array of competitively priced natural gas
   transportation and storage services for local distribution companies,
   marketers, brokers and industrial and commercial customers who
   contract directly with producers or marketers for their gas supplies.

                                     16

             During 1998, Columbia Transmission continued construction of
   the largest expansion of its storage and transportation system in its
   history.  In April 1999, the final phase of storage service began.
   Upon completion, the expansion will add approximately 500,000 Mcf per
   day of firm service.  Columbia Transmission is also participating in
   the proposed 442-mile Millennium Pipeline Project that has been
   submitted to FERC for approval.  As proposed, the project will
   transport approximately 700,000 Mcf per day of natural gas from
   Western Canada through the Lake Erie region to eastern markets.

             Columbia Gulf recently announced its participation in the
   proposed 160 mile, 24-inch diameter, Volunteer Pipeline Project.  As
   proposed, the project will transport approximately 250,000 dth/day
   from Portland, Tennessee to a point near Chattanooga, Tennessee.
   Columbia Gulf also announced plans in September 1998 to consider an
   expansion of its onshore East Lateral system at Grand Island,
   Louisiana to add approximately 600,000 Mcf per day of incremental firm
   gas transportation capacity.  Columbia Gulf is also participating in
   the proposed SunStar Pipeline project, a 56-mile offshore pipeline
   project with a capacity of 660,000 Mcf of natural gas per day from the
   Gulf of Mexico to its onshore lateral at Grand Isle, Louisiana.
   Columbia Gulf also owns a 33% interest in the Trailblazer Pipeline, a
   350-mile natural gas pipeline that extends from northeast Colorado to

   Columbia Resources is one of the largest-volume independent natural
   gas and oil producers in the Appalachian Basin.  Columbia Pipeline
   Corporation and its wholly owned subsidiary, Columbia Deep Water
   Services Company, were formed to operate pipeline and gathering
   facilities that are not regulated by FERC.

             Marketing Operations:  Columbia Energy Services Corporation
   ("Columbia Energy Services") and its subsidiaries conduct Columbia's
   non-regulated natural gas and electric power marketing operations and
   provide an array of energy supply and fuel management services to
   distribution companies, independent power producers and other large
   end-users both on and off Columbia's transmission and distribution
   pipeline systems.  Columbia Energy Services is also providing natural
   gas supplies to residential and small commercial customers as a result
   of the unbundling of services that is occurring at the local
   distribution level.  Columbia Energy Services, through its subsidiary,
   Columbia Service Partners, Inc. ("Columbia Service"), provides a
   variety of energy-related services to both homeowners and businesses.
   In 1997, Columbia Energy Services acquired PennUnion Energy Services
   L.L.C. ("PennUnion"), an energy-marketing affiliate of the Pennzoil
   Company.  In August 1999, Columbia Energy Services announced that it
   has decided to sell its wholesale gas and electric trading operations

   Petroleum Corporation, completed its acquisition of the propane and
   petroleum assets of Carlos R. Leffler, Inc., which added approximately
   12,500 propane customers and 36,600 petroleum customers.

             Columbia Electric Corporation's ("Columbia Electric")
   primary focus has been the development, ownership and operation of
   natural gas-fueled cogeneration power plants that sell electric power
   to local electric utilities under long-term contracts.  Columbia
   Electric is part owner in three cogeneration projects.  These
   facilities produce both electricity and useful thermal energy and are
   fueled principally by natural gas.  Columbia Electric holds various
   interests in these facilities, which have a total capacity of
   approximately 250 megawatts.

             In June 1998, Columbia Electric and LG&E Power Inc., a
   subsidiary of LG&E Energy Corporation, announced an agreement for
   Columbia to participate in the development of a gas-fired cogeneration

                                     18

   project that would have a total equivalent capacity of approximately
   550 megawatts.  The facility will provide steam and electric services
   to a Reynolds Metals plant in Gregory, Texas and will also provide
   electricity to the Texas energy market.  Construction began in August
   1998 and financing for the $257 million project was secured in
   November of 1998.

             In January 1998, Columbia Electric and Westcoast Energy Inc.
   signed a joint ownership agreement to develop three gas-fired electric
   generation plants by 2001.  In total, the three plants would provide
   approximately 1,000 megawatts of electricity using approximately 160
   MMcf per day of natural gas.  In August 1998, a site was purchased in
   Pennsylvania to build the first of these plants.  This plant will cost
   about $300 million to develop and will produce 500 megawatts of
   electricity and consume approximately 80 MMcf per day of natural gas.
   Each of the sponsors will own a 50% interest in the project.

             Columbia LNG Corporation is a partner with Potomac Electric
   Power Company in the Cove Point LNG Limited Partnership
   ("Partnership").  The Partnership owns one of the largest natural gas
   peaking and storage facilities in the United States located in Cove
   Point, Maryland.  The facility has the capacity to liquefy natural gas
   at a rate of 15,000 Mcf per day.  The facility enables liquefied
   natural gas to be stored until needed for the peak-day requirements of
   utilities and other large gas users.

        2.   Description of Utility Facilities

             a.   NiSource

                  i.   Natural Gas Utilities

             At June 30, 1999, the NiSource gas distribution system in
   Indiana included approximately 15,176 miles of distribution mains and
   737,664 customers.  In addition, Northern Indiana owns and operates
   underground gas storage facilities located at Royal Center, Indiana
   with a storage capacity of 6.75 billion cubic feet (Bcf), and a
   liquefied natural gas ("LNG") plant in LaPorte County, Indiana having
   a storage capacity of 4.0 Bcf, which is used for system pressure
   maintenance and peak season (November-March) deliveries.  Northern
   Indiana also holds under long-term contract storage capacity totaling
   approximately 9.11 Bcf in the Markham, Moss Bluff and Egan salt-dome
   storage caverns in Texas and Louisiana.  These facilities, which

                                     19

   provide Northern Indiana with a significant amount of "high
   deliverability" storage capacity,<12> are located at or near major
   supply "hubs" which have formed at locations where interstate
   pipelines serving the upper Midwest, Northeast, Gulf Coast,
   mid-Atlantic and Ohio Valley markets intersect.

             At June 30, 1999, NiSource's New England gas distribution
   utilities included some 5,508 miles of distribution mains, 116 miles
   of transmission lines and approximately 313,760 customers.  Bay State
   and Northern also own and operate LNG liquefaction, vaporization and
   storage facilities and propane storage tanks used to store
   supplemental and peak shaving supplies.  At June 30, 1999, NiSource's
   combined gas system consisted of 20,684 miles of distribution mains,
   together with associated compressing and regulating stations, LNG
   liquefaction, vaporization and storage facilities, propane storage
   tanks and 1,051,424 customers.

             Currently, NiSource's utilities purchase approximately 73%
   of their total system gas requirements from production in the onshore
   and offshore Texas and Louisiana producing areas, and approximately
   16% from production in the Mid-Continent (Oklahoma, Kansas and
   Arkansas), and Permian (West Texas) supply basins.  Gas produced from
   the Western Canadian Sedimentary Basin has also made up a significant
   portion of the gas supply portfolios of Bay State and Northern.  In
   1999, with the completion of new pipeline capacity from western Canada
   to the upper Midwest and New England markets, NiSource's gas
   distribution utilities in Indiana will have the opportunity to further
   diversify their gas portfolio through additional purchases of gas
   produced in the Western Canadian Sedimentary Basin (Alberta and
   British Columbia)<13>  NiSource estimates that, by 2002, western


   _______________

   <12>     "High deliverability," which is an operational characteristic
   of salt-dome storage caverns, means the ability to inject and withdraw
   gas on a frequent (I.E., daily) basis, year-round and at a high rate
   of flow.  Utilization of the capacity of such facilities is measured
   in terms of both their storage volume and frequency of the
   injection/withdrawal cycle (I.E., cycling).  In contrast, Northern
   Indiana's storage facilities in Indiana only allow for gas injection
   and withdrawal on a seasonal basis.  The "high deliverability"
   facilities in Texas and Louisiana provide Northern Indiana with added
   flexibility in managing deliveries to and from interstate pipelines,
   which, in turn, allows Northern Indiana to take advantage of price
   volatility and to balance its system load requirements on a daily
   basis.

   <13>     FERC granted certificate authority under Section 7(c) of the
   Natural Gas Act of 1938 ("NGA"), as amended, for a major expansion of
   the Northern Border Pipeline, which runs from the Montana-Saskatchewan
   border to its present terminus at Harper, Iowa, and a 243-mile
   extension thereof to a new terminus south of Chicago.  SEE NORTHERN
   BORDER PIPELINE CO., 76 FERC Para. 61,141 (1996); NORTHERN BORDER
                                                       (cont'd. on page 21)

                                     20

   Canadian gas could potentially account for as much as 40% of its total
   system supply for its Indiana gas utilities.

             NiSource's gas distribution subsidiaries have currently
   contracted for "firm" capacity and storage service on nine different
   long-haul interstate pipelines: ANR Pipeline Company ("ANR"), NGPL,
   Panhandle Eastern, PNGTS, Tennessee Gas, Texas Eastern Transmission
   Corp. ("Texas Eastern"), Texas Gas Transmission Corp. ("Texas Gas"),
   Transco and Trunkline.  NiSource's subsidiaries also have firm
   transportation capacity agreements with TransCanada PipeLines Limited
   ("TransCanada"), a Canadian interprovincial pipeline, and with several
   other regional pipelines, such as Algonquin Gas Transmission Company
   ("Algonquin"), Crossroads, Granite State and National Fuel Gas Supply
   Company ("National Fuel").

             NiSource projects that, as transmission constraints are
   eliminated and new pipeline capacity begins commercial service, the
   NiSource gas distribution utilities will be well positioned to
   purchase an increasing amount of their gas requirements from the
   Western Canadian Sedimentary, Appalachian and Michigan producing
   areas.  This gas will reach NiSource's Midwest and New England gas
   distribution utilities directly through new pipelines, such as PNGTS,
   Northern Border and Alliance, as well as indirectly by means of any
   one of several existing pipeline interconnections among Crossroads and
   Columbia Transmission, Tennessee Gas and PNGTS, Tennessee Gas and
   Columbia Transmission, Algonquin and Columbia Transmission and
   Northern Border's expansion into Northwest Indiana.

                  ii.  Electric Utility

             Northern Indiana owns and operates four coal-fired electric
   generating stations with net capabilities of 3,179 MW, two
   hydroelectric generating plants with net capabilities of 10 MW and
   four gas-fired combustion turbine generating units with net
   capabilities of 203 MW, for a total system net capability of 3,392 MW.
   During the year ended December 31, 1998, Northern Indiana generated
   93.3% and purchased 6.7% of its electric requirements.

   consists of 3,058 circuit miles of line.  The electric distribution
   system extends into 21 counties and consists of 7,814 circuit miles of
   overhead and 1,497 cable miles of underground primary distribution
   lines operating at various voltages ranging from 2,400 to 12,500
   volts.  Northern Indiana has distribution transformers having an
   aggregate capacity of 11,156,320 kva and 445,117 electric watt-hour
   meters.

             Northern Indiana's electric control area peak load (the
   highest level of electrical utility usage in the control area) of
   3,307 MW was set on July 30, 1999.  Northern Indiana's electric
   control area includes Northern Indiana, Wabash Valley Power
   Association, Inc. ("WVPA") and Indiana Municipal Power Agency
   ("IMPA").  Northern Indiana's internal peak load, which excludes WVPA
   and IMPA, of 2,962 MW, was also set on July 30, 1999.

             Northern Indiana's electric system is interconnected with
   the systems of American Electric Power, Commonwealth Edison Company,
   Cinergy Services, Inc., Consumers Energy and Ameren Services
   Corporation, formerly Central Illinois Public Service Company.
   Electric energy is purchased from, sold to, or exchanged with various
   other utilities and power marketers under Northern Indiana's power
   sales and open access transmission tariffs.

             Northern Indiana provides WVPA with transmission and
   distribution service, operating reserve requirements and capacity
   deficiency service, and provides IMPA with transmission service,
   operating reserve requirements and capacity deficiency service in
   Northern Indiana's control area.  Northern Indiana also engages in
   sales and services under interconnection agreements with WVPA and
   IMPA.     WVPA provides service to 12 Rural Electric Membership
   Corporations located in Northern Indiana's control area.  IMPA
   provides service to the municipal electric system of the city of
   Rensselaer located in Northern Indiana's control area.  Northern
   Indiana and WVPA have executed a supplemental agreement for unit
   peaking capacity and energy.  Unit peaking capacity is the capacity
   used to serve peak demand from a specific peaking generation unit.
   Pursuant to this agreement, which runs through December 2001, WVPA
   purchases 90 MW of capacity per month.

             Northern Indiana serves the Town of Argos as a full
   requirements customer and provides network integration service to
   seven municipal wholesale customers.

             Northern Indiana is a member of the East Central Area
   Reliability Coordination Agreement ("ECAR").  ECAR is one of nine
   regional electric reliability councils established to coordinate
   planning and operations of member electric utilities regionally and
   nationally.

             Fuel Supply:  The generating units of Northern Indiana are
   located at the Bailly, Mitchell, Michigan City and Schahfer Generating

                                     22

   Stations.  Northern Indiana's 13 steam generating units have a net
   capability of 3,179 MW.  Coal is the primary source of fuel for all
   units, except for three, which utilize natural gas.  In addition,
   Northern Indiana's four combustion turbine generating units with a net
   capability of 203 MW are fired by gas.  Fuel requirements for Northern
   Indiana's generation for 1998 were supplied as follows:

        Coal . . . . . . . . . . . . . . . . . 97.5%
        Natural Gas  . . . . . . . . . . . . .  2.5%

             In 1998, Northern Indiana used approximately 8.8 million
   tons of coal at its generating stations.  Northern Indiana has
   established a normal level of coal stock that is expected to provide
   adequate fuel supply during the year under all conditions.

             Columbia's natural gas public utility subsidiaries receive
   their natural gas supplies through Columbia's two wholly-owned
   interstate pipelines, Columbia Transmission and Columbia Gulf, major
   non-affiliated pipelines such as Panhandle Eastern, Tennessee Gas and
   Texas Eastern, and regional pipelines such as National Fuel and
   Equitrans, LP.  In addition to receiving supplies of Louisiana gas
   from Columbia Gulf, Columbia Transmission transports gas from
   Mid-Continent, onshore and offshore Texas, and western Canadian supply
   basins, through interconnections with ANR, Panhandle Eastern,
   Tennessee Gas, Texas Eastern, Texas Gas and Transco.  Columbia
   Transmission also transports Appalachian gas produced by Columbia's
   exploration and production subsidiaries and others, and both receives
   and transports Appalachian gas transported by Consolidated Natural Gas
   Company ("CNG") and Equitrans.

             Columbia's natural gas public utility subsidiaries have
   long-term firm transportation contracts with, among others, Columbia

                                     23

   Gas, Texas Eastern and Transco to meet the peak day needs of their
   customers.  In addition, the gas utilities have contractual access to
   the natural gas storage owned by Columbia Transmission.  Columbia
   Pennsylvania is the only gas utility to own underground storage,
   supported by eight wells on 3,300 acres.  Columbia Virginia and other
   unaffiliated LDC's subscribe to LNG storage services provided by
   Columbia Transmission from a facility located in Chesapeake, Virginia.
   Several of Columbia's gas utility subsidiaries subscribe to LNG
   storage services offered by Cove Point LNG.

             For the year 1998, NiSource understands that Columbia's
   natural gas public utility subsidiaries received significant amounts
   of natural gas supplies from Louisiana and Texas onshore or offshore
   sources, Appalachian Basin and Canada.

   A.   LEGAL ANALYSIS

        1.   Section 9(a)(2)

             Section 9(a)(2) makes it unlawful, without approval of the
   Commission under Section 10, "for any person . . . to acquire,
   directly or indirectly, any security of any public utility company, if
   such person is an affiliate . . . of such company and of any other
   public utility or holding company, or will by virtue of such
   acquisition become such an affiliate."  15 U.S.C. Section 79i(a)(2).
   Under the definition set forth in Section 2(a)(11), an "affiliate" of
   a specified company means "any person that directly or indirectly
   owns, controls, or holds with power to vote, 5 per centum or more of
   the outstanding voting securities of such specified company," and "any
   company 5 per centum or more of whose outstanding voting securities
   are owned, controlled, or held with power to vote, directly or
   indirectly, by, such specified company." 15 U.S.C. Section
   79b(a)(11)(A)-(B).

             Columbia Kentucky, Columbia Maryland, Columbia Ohio,
   Columbia Pennsylvania and Columbia Virginia are public utility
   companies as defined in Section 2(a)(5) of the Act.  Because NiSource
   will indirectly acquire (through Acquisition Corp.'s acquisition of
   Columbia) more than 5% of the voting securities of each of Columbia
   Kentucky, Columbia Maryland, Columbia Ohio, Columbia Pennsylvania and
   Columbia Virginia as a result of the Transaction, NiSource and
   Acquisition Corp. must obtain the approval for the Transaction under
   Sections 9(a)(2) and 10 of the Act.  The statutory standards to be
   considered by the Commission in evaluating the proposed Transaction
   are set forth in Sections 10(b), 10(c) and 10(f) of the Act.

                                     25

             As set forth more fully below, the Transaction complies with
   all of the applicable provisions of Section 10 of the Act and should
   be approved by the Commission:

             *    the consideration to be paid in the Transaction is fair
                  and reasonable;
             *    the Transaction will not create detrimental
                  interlocking relations or concentration of control;
             *    the Transaction will not result in an unduly
                  complicated capital structure for the NiSource system;
             *    the Transaction is in the public interest and the
                  interests of investors and consumers;
             *    the Transaction is consistent with Sections 8 and 11 of
                  the Act; and
             *    the Transaction will comply with all applicable state
                  laws.

             In addition, the Transaction is consistent with a number of
   the recommendations made by the Division of Investment Management in
   the report issued by the Division in June 1995 entitled "The
   Regulation of Public Utility Holding Companies" (the "1995 Report")
   and Commission precedent that has developed based upon these
   recommendations.<14>

        2.   Section 10(b)

             Section 10(b) provides that, if the requirements of Section
   10(f) are satisfied, the Commission shall approve an acquisition under
   Section 9(a) unless:

             (1)  such acquisition will tend towards interlocking
        relations or the concentration of control of public utility
        companies, of a kind or to an extent detrimental to the public
        interest or the interests of investors or consumers;

             (2)  in case of the acquisition of securities or utility
        assets, the consideration, including all fees, commissions, and
        other remuneration, to whomsoever paid, to be given, directly or
        indirectly, in connection with such acquisition is not reasonable
        or does not bear a fair relation to the sums invested in or the

   _______________

   <14>     For example, the Commission should "respond realistically to
   the changes in the utility industry and interpret more flexibly each
   piece of the integration equation," the "geographic requirements of
   Section 2(a)(29) [should be interpreted] flexibly, recognizing
   technical advances consistent with the purposes and provisions of the
   Act," the Commission's analysis should focus on whether the resulting
   system will be subject to effective regulation and the Commission
   should liberalize its interpretation of the "A-B-C" clauses and permit
   combination systems where the affected states agree. 1995 Report at
   71-77.

                                     26

        earning capacity of the utility assets to be acquired or the
        utility assets underlying the securities to be acquired; or

             (3)  such acquisition will unduly complicate the capital
        structure of the holding company system of the applicant or will
        be detrimental to the public interest or the interests of
        investors or consumers or the proper functioning of such holding
        company system.

   15 U.S.C. Section 79j(b).

             a.   Section 10(b)(1)

             i.   Interlocking Relationships

             Although any merger results in new links between heretofore
   unrelated companies, the relationships that will result from the
   Transaction are not the types of interlocking relationships prohibited
   by Section 10(b)(1), which was primarily aimed at preventing business
   combinations unrelated to operational and economic benefits to the
   integrated utility system.  SEE NORTHEAST UTILS., HCAR No. 25221, 1990
   SEC LEXIS 3898 at *33 (Dec. 21, 1990), MODIFIED, HCAR No. 25273 (Mar.
   15, 1991), AFF'D SUB NOM., CITY OF HOLYOKE V. SEC, 972 F2d 358 (D.C.
   Cir. 1992) ("interlocking relationships are necessary to integrate
   [the two merging entities]").  Under the circumstances of the Offer,no
   combination of the existing boards of NiSource and Columbia is
   currently proposed.

             ii.  Concentration of Control

             Section 10(b)(1) is intended to avoid "an excess of
   concentration and bigness" while preserving the "opportunities for
   economies of scale, the elimination of duplicate facilities and
   activities, the sharing of production capacity and reserves and
   generally more efficient operations" afforded by the coordination of
   local utilities into an integrated system.  AMERICAN ELEC. POWER CO.,
   HCAR No. 20633, 1978 SEC LEXIS 1103 at *25 (July 21, 1978).  In
   applying Section 10(b)(1) to utility acquisitions, the Commission must
   determine whether the acquisition will create "the type of structures
   and combinations at which the Act was specifically directed."  VERMONT
   YANKEE NUCLEAR POWER CORP., HCAR No. 15958, 1968 SEC LEXIS 925 at *15
   (Feb. 6, 1968).  As discussed below, the Transaction will not create a
   "huge, complex, and irrational system," but rather will afford the
   opportunity to achieve economies of scale and efficiencies which are
   expected to benefit investors and consumers.  AMERICAN ELEC. POWER
   CO., HCAR No. 20633, 1978 SEC LEXIS 1103 at *20 (July 21, 1978).

             Size:  If approved, the NiSource combined gas utility system
   will serve approximately 3.1 million gas customers in nine states and
   422,000 electric customers in Indiana.  As of June 30, 1999:  (1) the
   combined assets of NiSource and Columbia would have totaled
   approximately $17.23 billion and (2) the combined operating revenues

                                     27

   of NiSource and Columbia would have totaled approximately $10.7
   billion.

             By comparison, the Commission has approved acquisitions
   resulting in similarly sized and considerably larger holding
   companies.  See, e.g., TUC Holding Co., HCAR No. 26749 (Aug. 1, 1997)
   (acquisition of Texas Utility Company and ENSERCH Corp.; combined
   assets at the time of the acquisition over $21 billion); ENTERGY
   CORP., HCAR No. 25952 (Dec. 17, 1993) (acquisition of Gulf States
   Utilities; combined assets at the time of the acquisition in excess of
   $22 billion).

             As the following table demonstrates, there are numerous
   registered and non-registered holding company systems that are larger
   than NiSource will be following the Transaction in terms of assets,
   operating revenues, and number of customers.

      NiSource              17,051         10,308          3.1

             In addition, NiSource will be smaller than two of the
   registered holding companies to be formed as a result of recently
   announced mergers   American Electric Power Company, Inc. and Central
   & South West Corp. (combined 1998 year-end assets of approximately
   $33.23 billion and operating revenues of $11.83 billion) and Dominion
   Resources, Inc. and Consolidated Natural Gas Company (combined 1998
   year-end assets of approximately $28 billion, operating revenues of
   $8.8 billion and nearly 4 million customers)   and similar in size to
   a third recently announced merger, Northern States Power Company and
   New Century Energies, Inc. (combined 1998 year-end assets of
   approximately $15.09 billion and operating revenues of $6.43 billion).

             As consolidation within the energy industries continues, one
   would expect proposals for even larger holding company systems than
   exist today.  Nevertheless, following the consummation of the

   _______________

   <15>     Amounts are as of December 31, 1998.  The following
   information was derived from publicly-available sources and none of
   the information has been independently verified by NiSource.

                                     28

   Transaction, NiSource will be within the size range of the existing
   and emerging registered and exempt holding companies with which it
   will compete as competition in the converging utility industries
   increases.  As such, its operations would not exceed the economies of
   scale of current and developing holding company systems or provide
   undue power or control to NiSource in the regions in which it will
   provide service.

             Efficiencies and Economies:  In addition to analyzing the
   size of the utility system, the Commission also assesses the
   efficiencies and economies that can be achieved through the
   integration and coordination of utility operations.  More recent
   pronouncements of the Commission confirm that size is not
   determinative.  In CENTERIOR ENERGY CORP., HCAR No. 24073, 1986 SEC
   LEXIS 1655 at **6-7 (April 29, 1986), the Commission stated that a
   "determination of whether to prohibit enlargement of a system by
   acquisition is to be made on the basis of all the circumstances, not
   on the basis of size alone."  In addition, in the 1995 Report, the
   Division recommended that the Commission approach its analysis on
   merger and acquisition transactions in a flexible manner with emphasis
   on whether the Transaction creates an entity subject to effective
   regulation and is beneficial for shareholders and customers as opposed
   to focusing on rigid, mechanical tests.<16>

             By enhancing the size and geographic diversity of NiSource's
   existing gas system and combining NiSource's electric business with
   Columbia's gas business, the Transaction will significantly enhance
   each company's competitive position in an increasingly competitive
   energy market.  The electric and gas utility industries are merging in
   order to provide greater value to customers and, thus, allow companies
   to compete effectively in the increasingly competitive business
   environment.  By combining with NiSource's electric expertise and
   operations, Columbia's competitiveness, product offerings and ability
   to serve its customers will be enhanced.  In CONSOLIDATED NATURAL GAS
   CO., HCAR No. 26512, 1996 SEC LEXIS 1205 at **2, 17 (Apr. 30, 1996),
   the Commission recognized that "fundamental changes in the energy
   industry are leading to an increasingly competitive and integrated
   market, in which marketers deal in interchangeable units of energy
   expressed in British thermal unit values, rather than in natural gas
   or electricity.  To retain and attract wholesale and industrial
   customers, utilities need to provide competitively priced power and
   related customer services. . . .  It appears that the restructuring of
   the electricity industry now underway will dramatically affect all
   United States energy markets as a result of the growing
   interdependence of natural gas transmission and electric generation,
   and the interchangeability of different forms of energy, particularly
   gas and electricity."  The combination offers the same type of
   synergies and efficiencies that were sought and are now being realized
   by the applicants (both exempt and registered) in TUC HOLDING CO.,

   Cir. 1999); and NEW CENTURY ENERGIES, INC., HCAR No. 26748 (Aug. 1,
   1997).

             Competitive Effects:  As the Commission noted in NORTHEAST
   UTILS., HCAR No. 25221, 1990 SEC LEXIS 3898 at *39 (Dec. 21, 1990),
   the "antitrust ramifications of an acquisition must be considered in
   light of the fact that public utilities are regulated monopolies and
   that federal and state administrative agencies regulate the rates
   charged consumers."  On July 19, 1999, NiSource filed the Notification
   and Report Forms with the Department of Justice ("DOJ") and Federal
   Trade Commission pursuant to the Hart-Scott-Rodino Antitrust
   Improvements Act of 1976, 15 U.S.C. Section 1311, ET SEQ. Act ("HSR
   Act") describing the effects of the Transaction on competition in the
   relevant market.  It is a condition to the consummation of the
   Transaction that the applicable waiting periods under the HSR Act
   shall have expired or been terminated.  The HSR waiting period expired
   on August 4, 1999.

             In addition, FERC reviews the effects of jurisdictional
   transactions on competition, rates and regulation.  A copy of the
   application to be filed by NiSource with FERC will be filed by
   amendment to this Application/Declaration and will demonstrate the
   absence of any anti-competitive effects.

             In the context of the foregoing review, the Transaction will
   not "tend towards interlocking relations or the concentration of
   control" of public utility companies, of a kind or to the extent
   detrimental to the public interest or the interests of investors or
   customers within the meaning of Section 10(b)(1).  15 U.S.C. Section
   79j(b)(1).

             b.   Section 10(b)(2)   Fairness of Consideration

             Section 10(b)(2) requires the Commission to determine
   whether the consideration to be given by NiSource to the holders of
   Columbia common stock in connection with the Transaction is reasonable
   and whether it bears a fair relation to investment in and earning
   capacity of the utility assets underlying the securities being
   acquired.  On Friday, June 4, 1999, the last full trading day before
   the first public announcement of NiSource's proposal to acquire
   Columbia, the closing sale price per share of Columbia common stock on
   NYSE was $55   per share.  On June 23, 1999, the last full trading day
   before the public announcement of the Offer, the closing sale per
   share of Columbia's common stock on NYSE was $63  per share.  The
   fairness of the Transaction's consideration is evidenced by the fact
   that NiSource is offering $6.1 billion, or $74 per share, in cash for
   all outstanding shares of  Columbia's common stock.  This offer
   represents a 28% premium over the average closing share price for
   Columbia's common stock for the 30 trading days ending October 15,

                                     30

   1999 and a 45% premium over the average closing share price for
   Columbia's common stock for the 30 trading days before the first
   public announcement of NiSource's Offer to acquire Columbia.  In
   addition, as demonstrated in the table below, the quarterly price data
   of Columbia common stock  for the years 1997, 1998 and 1999 support
   the fairness of NiSource's tender offer.  The per share price offered
   is considerably above Columbia's highest price prior to the
   announcement of NiSource's proposal for Columbia.

     NiSource's Offer was priced after analysis and evaluation of the
   assets, liabilities and business prospects of Columbia and of a
   combined company.  Moreover, in the context of a direct offer to
   Columbia's shareholders, a presumption must exist that the price is
   fair.  In such circumstances, the price will be evaluated by market
   forces.

             In light of the foregoing, including an analysis of the
   recent trading history of Columbia's common stock, NiSource and
   Acquisition Corp. believe that the offer falls within the range of
   reasonableness and that the Offer bears a fair relation to the sums
   invested in, and the earning capacity of, Columbia's utility assets.

             c.   Section 10(b)(2)   Reasonableness of Fees

             NiSource believes that the overall fees and expenses to be
   incurred in connection with the Transaction will be found reasonable
   in light of the Transaction's size and complexity relative to similar
   acquisitions and the anticipated benefits of the Transaction to the

   public, investors and consumers.  Details of such fees and expenses
   will be provided by amendment to this Application/Declaration.

             d.   Section 10(b)(3)   Capital Structure

             Section 10(b)(3) requires the Commission to determine
   whether the Transaction will unduly complicate NiSource's capital
   structure or will be detrimental to the public interest, the interests
   of investors or consumers or the proper functioning of NiSource's
   system.

             The capital structure of NiSource after the Transaction will
   not be unduly complicated and will be substantially similar to capital
   structures approved by the Commission in recent orders.  A corporate
   organizational chart of NiSource and Columbia will be filed by
   amendment to this Application/Declaration.  Although NiSource has not
   conclusively determined its corporate structure after the Transaction
   is consummated, it intends to undertake several significant steps to
   simplify its organizational structure.  Once the final structure is
   determined, NiSource will file an amendment to this
   Application/Declaration which describes its corporate structure and
   provide an organizational chart of NiSource after consummation of the
   Transaction.

             Set forth below are summaries of the capital structures of
   NiSource and Columbia as of June 30, 1999:

             The debt financing by NiSource of Columbia's acquisition
   represents only short-term bridge financing.  Although the combined
   cash flow of NiSource and Columbia would comfortably service the
   interest requirements of the Facility under reasonable interest rate
   assumptions, NiSource intends to replace the Facility with the
   issuance of equity and debt in order to improve its debt/equity ratio
   after consummation of the Transaction.   In refinancing the Facility,
   it will issue equity and other securities to establish a debt/equity
   ratio consistent with the business environment in which it operates
   and comparable to other registered public utility holding companies.
   As previously noted, prior to the consummation of the Transaction,
   NiSource will file a separate Application/Declaration under the Act
   with respect to the refinancing of the Facility and with respect to
   its ongoing financing activities after giving effect to the
   Transaction.

        3.   Section 10(c)

             Section 10(c) of the Act provides that, notwithstanding the
   provisions of Section 10(b), the Commission shall not approve:

        (1)  an acquisition of securities or utility assets, or of any
        other interest, which is unlawful under the provisions of section
        8 or is detrimental to the carrying out of the provisions of
        section 11;<18> or

        (2)  the acquisition of securities or utility assets of a public
        utility or holding company unless the Commission finds that such
        acquisition will serve the public interest by tending towards the
        economical and the efficient development of an integrated public
        utility system.

   15 U.S.C. Section 79j(c).

             a.   Section 10(c)(1)

             Section 10(c)(1) requires that an acquisition be lawful
   under Section 8 of the Act.  Section 8 prohibits registered holding
   companies from acquiring, owning interests in or operating both a gas
   and an electric utility serving substantially the same area if it is
   prohibited by state law.  As discussed below, the Transaction does not
   raise any issues under Section 8 of the Act.  Indeed, Section 8
   indicates that a registered holding company may own both gas and


   _______________

   <18>     By their terms, Sections 8 and 11 only apply to registered
   holding companies and are therefore inapplicable at present to
   NiSource, since it is not now a registered holding company.  The
   following discussion of Sections 8 and 11 is included only because,
   under the present transaction structure, NiSource will register as a
   holding company after consummation of the Transaction.

                                     33

   electric utilities where the relevant state utility commission permits
   such an arrangement.

             Section 10(c)(1) also requires that the transactions not be
   detrimental to carrying out the provisions of Section 11 of the Act.
   Section 11(a) of the Act requires the Commission to examine the
   corporate structure of registered holding companies to ensure that
   unnecessary complexities are eliminated and voting powers are fairly
   and equitably distributed.  As described above in ITEM 3.A.2, the
   Transaction will not result in unnecessary complexities or unfair
   voting powers.

             Section 11(b)(1) of the Act generally requires a registered
   holding company system to limit its operations "to a single integrated
   public-utility system, and to such other businesses as are reasonably
   incidental, or economically necessary or appropriate to the operations
   of such integrated public-utility system." 15 U.S.C. Section
   79k(b)(1).  However, Section 11(b)(1) further provides that "one or
   more additional integrated public-utility systems" may be retained if
   certain criteria are met.  ID.  Section 11(b)(2) directs the
   Commission "to ensure that the corporate structure or continued
   existence of any company in the holding-company system does not unduly
   or unnecessarily complicate the structure, or unfairly or inequitably
   distribute voting power among security holders, of such
   holding-company system." 15 U.S.C. Section 79k(b)(2).

             As detailed below, the Transaction is lawful under Section 8
   and is not detrimental to carrying out the provisions of Section 11.

             i.   Retention of Electric Operations

             NiSource's retention of the electric operations of Northern
   Indiana is lawful under Section 8 of the Act and is not detrimental to
   carrying out the provisions of Section 11 of the Act.
             Section 8 of the Act provides that:

        Whenever a State law prohibits, or requires approval or
        authorization of, the ownership or operation by a single
        company of the utility assets of an electric utility company
        and a gas utility company serving substantially the same
        territory, it shall be unlawful for a registered holding
        company, or any subsidiary company thereof . . . (1) to take
        any step, without the express approval of the State
        commission of such State, which results in its having a
        direct or indirect interest in an electric utility company
        and a gas company serving substantially the same territory;
        or (2) if it already has any such interest, to acquire,
        without the express approval of the State commission, any
        direct or indirect interest in an electric utility company
        or gas utility company serving substantially the same
        territory as that served by such companies in which it
        already has an interest.
                                     34

   15 U.S.C. Section 79h.  A plain reading of Section 8 indicates that,
   with the approval of the relevant state utility commissions, a
   registered holding company can include both electric and gas utility
   systems.  A more detailed examination of Section 8 in light of its
   legislative history indicates that the purpose of this section is to
   preclude ownership by a registered holding company of separate gas and
   electric utility companies with overlapping service territories in an
   attempt to circumvent state law restrictions that preclude ownership
   of gas and electric assets by the same company.<19>

             Section 8 of the Act and the public interest both permit
   NiSource's retention of its Northern Indiana operations upon
   completion of the Transaction and NiSource's registration as a holding
   company.  NiSource's existing gas and electric operations in Indiana,
   which are in overlapping service territories, are in conformity with
   Indiana law.  These utility operations will not change as a result of
   the Transaction.  Consequently, NiSource is not using its holding
   company structure to circumvent state regulation.  The IURC currently
   exercises, and will continue to exercise, jurisdiction over NiSource's
   Indiana gas and electric operations.

             In addition to Section 8 of the Act, Section 11 contains
   provisions that permit the retention by NiSource of Northern Indiana's
   electric operations.  Section 11(b)(1) of the Act permits a registered
   holding company to control one or more additional integrated public
   utility systems   i.e., electric as well as gas utility systems   if:

             (A)   each of such additional systems cannot be operated as
             an independent system without the loss of substantial
             economies which can be secured by the retention of control
             by such holding company of such system;

             (B)  all of such additional systems are located in one
             state, adjoining states, or a contiguous foreign country;
             and

             (C)  the continued combination of such systems under the
             control of such holding company is not so large (considering
             the state of the art and the area or region affected) as to
             impair the advantages of localized management, efficient
             operation, or the effectiveness of regulation.

   <19>     The Report of the Committee on Interstate Commerce, S. Rep.
   No. 621 at 29 (1935) (Section 8 of the Act "is concerned with
   competition in the field of distribution of gas and electric energy
   a field which is essentially a question of State policy, but which
   becomes a proper subject of Federal action where the extra-State
   device of a holding company is used to circumvent state policy.").

                                     35

   15 U.S.C. Section 79k(b)(1).  These three subsections of Section
   11(b)(1) are frequently referred to as the "ABC Clauses" and each
   clause is addressed separately below.

             Clause A: The Commission has interpreted Clause A "to
   require an affirmative showing by a registrant that an additional
   system could not be operated under separate ownership without a loss
   of economies which are 'so important as to cause a serious impairment
   of that system' and 'substantial in the sense that they were important
   to the ability of the additional system to operate soundly.'"  NEW
   CENTURY ENERGIES, INC., HCAR No. 26748, 1997 SEC LEXIS 1583 at **44-45
   (Aug. 1, 1997), quoting New England Elec. Sys., HCAR No. 15035, 1964
   SEC LEXIS 999 at **9, 12 (Mar. 19, 1964).  A registered holding
   company generally satisfies the requirements of Clause A by preparing
   a "divestiture" or "severance" study which examines the estimated loss
   of economies precipitated by a hypothetical divestiture "expressed in
   terms of the ratio of increased expenses to the system's total
   operating revenues, operating revenue deductions (excluding federal
   income taxes), gross income and net income before federal income
   taxes."  ID. at *47 n.52.  In an early leading decision, the
   Commission found that cost increases which resulted in a 6.78% loss of
   operating revenues, a 9.72% increase in operating revenues deductions,
   a 25.44% loss of gross income and a 42.46% loss of net income provided
   an "impressive basis for finding a loss of substantial economies."
   ENGINEERS PUB. SERV. CO., HCAR No. 3796, 1942 SEC LEXIS 941 at *43
   (Sept. 17, 1942), REV'D ON OTHER GROUNDS AND REMANDED, 138 F.2d 936
   (D.C. Cir. 1943), VACATED AS MOOT, 332 U.S. 788 (1947).

             NiSource will prepare a divestiture study with respect to
   Northern Indiana which it expects will demonstrate substantial lost
   economies if NiSource is required to divest Northern Indiana.  These
   lost economies will result from the need to replicate corporate and
   administrative services, lost economies of scale and the costs of
   reorganization, and will be described more fully in the divestiture
   study which will be filed as an amendment to this
   Application/Declaration.

             In addition to quantitative factors, the Commission also
   considers qualitative factors in its determination under Clause A.
   First, the Commission in recent decisions has approved the retention
   by registered holding companies of combination gas and electric
   systems because "separation of gas and electric businesses may cause
   the separated entities to be weaker competitors than they would be
   together." NEW CENTURY ENERGIES, INC., HCAR No. 26748, 1997 SEC LEXIS
   1583 at *52 (Aug. 1, 1997); CINERGY CORP., HCAR No. 26934, 1998 SEC
   LEXIS 2377 at *8 (Nov. 2, 1998); WPL HOLDINGS, INC., HCAR No. 26856,

                                     36

   GAS AND ELEC. CO. V. SEC, 168 F.3d 1337 (D.C. Cir. 1999).<20>  Due
   to the recent wave of mergers between electric and gas utilities
   (E.G., Duke Power Company/PanEnergy Corp., Houston Industries,
   Inc./NorAm Energy Corporation, Enron Corporation/Portland General
   Corporation, Dominion Resources, Inc./Consolidated Natural Gas
   Company), NiSource's competitive position in the market could suffer
   because as the utility industry moves toward a complete energy
   services concept, competitive companies must be able to offer
   customers a range of options to meet their energy needs.  The
   combination of electric and gas operations in a single company offers
   that company a means to compete more effectively in the emerging
   energy services business.  SEE WPL HOLDINGS, INC., HCAR No. 26856
   (Apr. 14, 1998), AFF'D SUB NOM., MADISON GAS & ELEC. CO. V. SEC , 168
   F.3d 1337 (D.C. Cir. 1999).  Proposed transactions should continue to
   be evaluated in light of this continuing evolution in the utility
   industries.  Second, the Commission has noted that the DOJ and FERC
   typically have concomitant jurisdiction over public utility mergers
   and typically consider anticompetitive consequences of any proposed
   transactions. NEW CENTURY ENERGIES, INC., HCAR No. 26748, 1997 SEC
   LEXIS 1583 at *55 (Aug. 1, 1997).  The Transaction is expressly
   conditioned on the approval of the DOJ.  Third, the Commission
   considers whether the electric and gas properties have long been under
   common control and whether retention would alter the STATUS QUO with
   respect to utility operations.  Northern Indiana's electric and gas
   operations have been under common control since 1926 and permitting
   the retention of Northern Indiana's electric business would not alter
   the STATUS QUO with respect to its utility operations.  Finally, the
   Commission determines whether the proposed acquisition has not
   "elicited any adverse reaction from interested state commissions." Id.
   at *56.  This factor should not present a problem either because the
   Transaction is expressly conditioned upon NiSource receiving all
   necessary regulatory approvals from the relevant state commissions.
   The Transaction will not go forward unless NiSource satisfies any
   reservations the relevant state commissions may have regarding the
   Transaction.

             Clause B:  The requirements of Clause B are met because
   Northern Indiana's electric operations are located in the same state
   as its gas operations   their service territories physically overlap
   and are located in an adjoining state to Columbia's gas operations in
   Ohio.

   _______________

   <20>     The Commission further noted that the "empirical basis" for
   the assumptions underlying its decision in NEW ENGLAND ELEC. SYS.,
   HCAR No. 15035 (Mar. 19, 1964), REV'D, SEC V. NEW ENGLAND ELEC. SYS.,
   346 F.2d 399 (1st Cir. 1965), REV'D AND REMANDED, 384 U.S. 176 (1966),
   ON REMAND, 376 F.2d 107 (1st Cir. 1967),  REV'D, 390 U.S. 207 (1968)
   was "rapidly eroding."  NEW CENTURY ENERGIES, INC., HCAR No. 26748,
   1997 SEC LEXIS 1583 at *54 (Aug. 1, 1997).

                                     37

             Clause C:  The requirements of Clause C are met because the
   continued combination of the electric and gas operations under
   NiSource is not so large (considering the state of the art and the
   area or region affected) as to impair the advantages of localized
   management, efficient operation or the effectiveness of regulation.
   Northern Indiana's electric system is confined to a relatively small
   geographic area.  NiSource will maintain management of electric
   operations geographically close to Northern Indiana's electric
   operations, thereby preserving the advantages of localized management.
   Northern Indiana's electric operations will also remain subject to the
   IURC's jurisdiction, thereby maintaining the effectiveness of
   regulation.  Finally, Northern Indiana's electric operations enjoy
   substantial economies as part of the NiSource system, and will realize
   additional economies as a result of the Transaction from becoming part
   of a combined NiSource/Columbia system.  Far from impairing the
   advantages of efficient operation, the continued combination of
   Northern Indiana's electric and gas operations will continue to
   facilitate and enhance efficiency.

             ii.  Non-Utility Businesses

             Section 11(b)(1) limits the non-utility interests of a
   registered holding company to "interests that are 'reasonably
   incidental, or economically necessary or appropriate to the operations
   of such integrated public-utility system,' on a finding by the
   Commission that such interests are 'necessary or appropriate in the
   public interest or for the protection of investors or consumers and
   not detrimental to the proper functioning' of the integrated system."
   NEW CENTURY ENERGIES, INC., HCAR No. 26748, 1997 SEC LEXIS 1583 at *36
   n.37 (Aug. 1, 1997).  "The Commission has interpreted these provisions
   to require the existence of an operating or functional relationship
   between the utility operations of the registered holding company and
   its nonutility activities."  ID. at *62 n.70.

             Rule 58 provides exemptions for investments in certain
   energy related businesses up to the greater of $50 million or 15% of
   the consolidated capitalization of such registered holding company.
   17 C.F.R. Section 250.58.  Further, the Commission has determined that
   existing investments in energy-related companies (as of the date of
   the consummation of the merger) of an exempt holding company which
   became a registered holding company as a result of the merger should
   be disregarded for purposes of calculating the dollar limitations
   imposed by Rule 58.  SEE NEW CENTURY ENERGIES, INC., HCAR No. 26748,
   1997 SEC LEXIS 1583 at *63 (Aug. 1, 1997); AMEREN CORP., HCAR No.
   26809, 1997 SEC LEXIS 2719 at **39-40 (Dec. 30, 1997); CONECTIV, INC.,
   HCAR No. 26832, 1998 SEC LEXIS 326 at *42 (Feb. 25, 1998).

             NiSource is currently a holding company that is exempt from
   the registration requirements of the Act.  As an exempt holding
   company, NiSource has been free to invest in a variety of non-utility
   businesses and activities without the need to obtain prior Commission
   approval under Section 9(a) of the Act.  The Transaction will result

                                     38

   in NiSource becoming a registered holding company.  Therefore, it is
   necessary to evaluate each of NiSource's nonutility business
   activities within the retention restrictions of the Act and the
   Commission's rules promulgated thereunder.  Columbia has been subject
   to regulation as a registered holding company for an extended period.
   Therefore, Columbia's ability to engage in nonutility businesses has
   been subject to the approval requirements of Section 9, and each of
   Columbia's existing nonutility businesses has been either approved by
   the Commission or falls within the exemptions of Rule 58.
   Consequently, the discussion below focuses on the retention of
   NiSource's nonutility businesses as appropriate either under the
   exemptions of Rule 58 or prior Commission precedent.  Most of
   NiSource's non-utility businesses are demonstrably functionally
   related to its gas and electric utility operations.  In addition,
   NiSource believes that significant equitable arguments support the
   retention of its various non-utility businesses.<21>

             Natural Gas Pipeline, Storage and Gathering:  NiSource has
   two wholly-owned interstate natural gas pipeline subsidiaries.
   Crossroads operates an interstate pipeline from Indiana to Ohio
   connecting NGPL, Trunkline and Panhandle Eastern with Columbia
   Transmission and gas utility customers in Ohio and Indiana. Granite
   State operates an interstate pipeline extending from Massachusetts,
   where it interconnects with Tennessee Gas, through New Hampshire and
   into Maine, where it interconnects at several points with PNGTS.
   Granite State serves Northern and Bay State in all three states.  In
   addition, NiSource indirectly owns an interest in a pipeline in
   northern New England, an intrastate natural gas pipeline in Texas and
   natural gas salt cavern storage facilities.

             These companies engage in "gas-related activities" under
   Section 2(a) of the Gas-Related Activities Act of 1990 ("GRAA").  The
   ownership of such businesses is authorized under Rule 58(a)(2) and
   such businesses have routinely been permitted to be retained in prior
   Commission orders approving mergers and the creation of new registered
   holding companies.  WPL HOLDINGS, INC., HCAR No. 26856, 1998 SEC LEXIS

             Exploration and Production Operations: EnergyUSA has equity
   interests in a domestic oil and gas producer with properties located
   in Texas, Oklahoma and Louisiana and a Canadian oil and gas producer.

   <21>     In addition to the non-utility businesses listed below,
   NiSource currently owns interests in several non-utility businesses
   which are either inactive or which it is in the process of divesting.

             The exploration of natural resources or the holding of
   rights to such resources are "gas-related activities" under Section
   2(b) of the GRAA.  The ownership of such businesses is authorized
   under Rule 58(a)(2) and such businesses have routinely been permitted
   to be retained in prior Commission orders approving mergers and the
   creation of new registered holding companies.  WPL HOLDINGS, INC.,

             Energy-Related Projects:  NiSource's subsidiary, Primary,
   arranges energy-related projects for large energy-intensive facilities
   through Harbor Coal, North Lake, LEC, Portside, CE and Whiting.  The
   SEC Staff issued a no-action letter concurring with NiSource that
   North Lake is not an "electric utility" under Section 2(a)(3) of the
   Act with respect to its involvement in the processing of steam into
   electricity which is owned and used solely by Ispat in its
   manufacturing operations.  NIPSCO INDUS., INC., 1996 SEC No-Act.
   LEXIS 541 (Jan. 19, 1996).  Lakeside, Portside and CE process steam
   into electricity under similar circumstances to North Lake.  Whiting
   recently announced an agreement with Amoco Oil Company to lease and
   operate a net 525 MW natural-gas fired cogeneration facility adjacent
   to Amoco's refinery in Whiting, Indiana.  None of Primary's
   subsidiaries engages in activities that would cause it to be a public
   utility company under the Act.  The Commission has permitted newly
   registered holding companies to retain businesses which provide
   operation and maintenance services to generating facilities and the
   sale of steam to residential, commercial and industrial customers.

   Services, Inc., a wholly-owned subsidiary of Development, participates
   with IBM in a joint venture to enhance a CIS system (and training for
   the system) which it markets to other utilities.  The Commission has
   permitted retention by registered holding companies of a business that
   provides technical and consulting services, including billing services
   and information systems or data processing, to affiliated and
   non-affiliated companies.  CONECTIV, INC., HCAR No. 26832, 1998 SEC

   permitted under Rule 58 (b)(l)(vii), since they involve technical
   expertise developed in the course of utility operations.

             Water Utilities:  The Water Utilities supply water for
   residential, commercial and industrial uses in Indianapolis, Indiana
   and surrounding areas.  Precedent exists for the retention of such
   water utilities and related activities by newly registered holding
   companies under circumstances where the divestiture of such interests

                                     41

   would result in economic inequities and where such activities
   represent a small portion of the registered holding company's
   operations.

             The Water Utilities represent only a small portion of
   NiSource's total operations.  In 1998, the Water Utilities had
   operating revenues of $84 million.  This figure represents less than
   one percent of the $10.3 billion PRO FORMA combined operating revenues
   of NiSource following consummation of the Transaction.  The Commission
   has previously authorized retention of water utilities by a newly
   registered holding company that had a similar, DE MINIMIS effect on
   the holding company's overall revenues.  WPL HOLDINGS, INC., HCAR No.
   26856, 1998 SEC LEXIS 676 at *73 (Apr. 14, 1998), AFF'D SUB NOM.,
   MADISON GAS & ELEC. CO. V. SEC, 168 F.3d 1337 (D.C. Cir. 1999).

             NiSource's ownership of the Water Utilities results in
   significant savings to the water customers through economies of scale
   provided by NiSource.  All of NiSource's subsidiaries benefit from
   shared administrative services, such as payroll, tax, and financial
   reporting software.  Potential cost savings are also present through
   combined billing, call center, dispatching services and lowered
   capital expenditures.  NiSource will prepare and file by amendment to
   this Application/Declaration a divestiture study for the Water
   Utilities and it anticipates that significant lost economies will
   result if NiSource is required to divest the Water Utilities.

             NiSource's ownership of the Water Utilities also provides
   financial benefits to NiSource's gas and electric utility
   subsidiaries.  NiSource realizes property tax advantages for its gas
   and electric utilities by combining water property holdings with gas
   and electric holdings.

             In addition to the financial benefits that result to
   NiSource and its customers, NiSource's ownership of the Water
   Utilities also represents a strategic business opportunity as the
   competition in the energy industries accelerates and the natural gas
   and electric utility industries continue to deregulate.  The ownership
   of water utilities, as well as gas and electric utilities, will
   enhance NiSource's ability to provide essential resources to all of
   its customers.  The Water Utilities are strategically located less
   than 50 miles from NiSource's electric and gas service territory.
   Through its strong reputation in Indiana as a leading provider of
   electric and gas service, and through the customer loyalty it is
   building by providing quality service to its water customers, NiSource
   is in a strategic position to provide multiple energy services to all
   of its customers once deregulation occurs in Indiana.

             The Commission recently permitted Alliant Energy Corp., a
   newly registered holding company, to retain ownership of three water
   utilities under similar circumstances.  WPL HOLDINGS, INC., HCAR No.

                                     42

   justify retention of the Water Utilities by reference to such
   precedent and is preparing a study to address the economic
   consequences of divestiture.

             Waste Water Treatment:  IWC Services, Inc., a wholly-owned
   subsidiary of IWCR, has a 52% interest in the White River
   Environmental Partnership that provides waste water treatment services
   for the cities of Gary, Plainfield and Indianapolis, Indiana.  The

             Utility Related Services:  SM&P and other NiSource
   subsidiaries perform underground utility locating and marking services
   in Indiana and other states.  Miller installs, repairs and maintains
   underground pipelines used in gas, water and sewer transmission and
   distribution systems.  SM&P provides services to four utility
   industries   telephone, gas, electricity and water.  Miller provides
   services to both gas and water utilities.  The Commission has approved

             Financing:  Capital Markets provides financing for
   NiSource's non-utility subsidiaries and certain utility subsidiaries.
   The Commission has on a number of occasions authorized registered
   holding companies to own subsidiaries that provide financing and
   related financial services to their affiliated companies.  SEE

             Real Estate:  NiSource and its subsidiaries have invested in
   several different types of real estate ventures.  These fall into
   several different categories, as described below.

                                     43

             *    A wholly-owned subsidiary of Development manages or
                  sells off excess real estate owned by Development and
                  other NiSource subsidiaries.  These investments are
                  functionally related to the activities of system
                  utilities and therefore, under Commission precedent,
                  NiSource should be allowed to retain the investment
                  after NiSource becomes a registered holding company.

             *    JOF Transportation Company, a wholly-owned subsidiary
                  of Development, owns a 40% passive interest in railroad
                  assets in the vicinity of several electric generating
                  plants owned by Northern Indiana and which Northern
                  Indiana currently uses to deliver coal to its electric
                  generating plants.  Retention of NiSource's interest
                  would enable it to construct additional power lines or
                  gas pipelines in the future and to ensure continued
                  access to tracks needed to deliver coal to electric
                  generating plants owned by Northern Indiana.  The
                  Commission has held that a registered public utility
                  holding company may hold property that will be needed

             *    NDC Douglas Properties, Inc., a wholly-owned subsidiary
                  of Development, has 15 passive interests in multiple-
                  family residential developments, most of which are in

                  the service territory of NiSource's utility
                  subsidiaries.  These investments are divided into six
                  limited partnerships and nine limited liability
                  companies and are held by NiSource in order to generate
                  low-income housing tax benefits under Section 42 of the
                  Internal Revenue Code.  The investments are part of the
                  continued commitment by NiSource to provide high
                  quality, energy efficient, affordable housing to the
                  residents of various geographic and economic regions
                  served by its utilities.  The Commission has allowed

                  is a passive investor and that the purpose of the

                  revitalize downtown Kokomo, Indiana, which is in the

             *    Lake Erie Land Company ("Lake Erie"), a wholly-owned
                  subsidiary of Development, owns wetlands that can be
                  used as offsets to enable developers to obtain approval
                  for projects that require filling of wetlands.  These
                  offsets could be used for construction projects by
                  NiSource system utilities and are also sold to other
                  developers in need of offsets.  Because it is difficult
                  and economically inefficient to identify discrete,
                  small tracts of wetlands to be restored each time a
                  need for a small amount of offsets arises, it is
                  beneficial to have a large bank of restored wetlands
                  available to serve these needs as they arise and to
                  sell the offsets to third parties to the extent that
                  the available bank exceeds near term utility system
                  needs.  Commission precedent supports the retention of
                  property held for future utility needs.  WPL HOLDINGS,

                  larger tracts of wetlands are environmentally
                  preferable to smaller tracts that collectively comprise
                  the same number of acres.  Thus, NiSource is able to
                  serve as a good environmental citizen as well as
                  meeting its system utility needs for wetlands offsets
                  by holding tracts of restored wetlands larger than the
                  minimum necessary for the foreseeable needs of its
                  system utilities.  Divestiture of these assets would
                  impose an economic hardship because of the difficulty
                  and expense NiSource would incur if it had to purchase
                  wetlands each time it needed wetlands offsets for
                  utility development.

                  Lake Erie and a subsidiary also develop and operate
                  tracts of land which were initially purchased in
                  bankruptcy within the service territories of NiSource
                  utility subsidiaries into model communities that serve
                  community development and environmental interests.  In
                  order to assure the developments meet NiSource's goals
                  for architectural, urban planning, and environmental
                  considerations, NiSource has made an active investment
                  in these projects.  These investments, however,
                  represent approximately $62 million or just over 1% of
                  NiSource's net assets, and they are managed by a
                  subsidiary that is separate from the system utility
                  companies, so that any losses from these projects will
                  have no adverse impact on the utilities or their
                  ratepayers.  NiSource requests that the Commission
                  permit retention of this investment, given that these
                  projects impose no significant risks on ratepayers and
                  taking into consideration the economic hardship that
                  NiSource would suffer if it were required to divest
                  itself of these projects after the substantial
                  investments it has made to ensure that the developments
                  meet the established community development, urban
                  planning and environmental goals.  The Commission has
                  allowed retention of real estate operations created by
                  exempt holding companies before becoming registered
                  even though such operations were not strictly related
                  to utility operations.  WPL HOLDINGS, INC., HCAR No.

             b.   Section 10(c)(2)

             The Transaction will tend toward the economical and
   efficient development of an integrated public utility system, thereby
   serving the public interest, as required by Section 10(c)(2) of the
   Act.

             i.   Efficiencies and Economies

             The Commission should find that the Transaction is likely to
   produce substantial economies and efficiencies over time, chiefly in
   the areas of coordinated gas supply for the combined gas distribution
   utilities and coordinated utilization and optimization of interstate
   pipeline and storage capacity and gas storage deliverability.  The
   Transaction will also produce economies and efficiencies relating to
   the development and marketing of energy services, both regulated and
   unregulated.  The Transaction will make it possible for NiSource's and
   Columbia's gas distribution utilities to combine their separate
   portfolios of gas supply, transportation and storage arrangements.
   This will make the combined entity a larger volume participant in
   common supply basins and at market hubs and centers.  Having this
   larger volume position will enable the combined entity to achieve
   larger savings and create greater efficiencies than NiSource and
   Columbia distribution utilities could achieve independently,
   increasing their purchasing power and creating flexibility in
   balancing demand and supply requirements of their combined utility
   systems.  Moreover, as the dynamics in the natural gas industry
   continue to change (E.G., in response to the impact of growing
   Canadian gas supplies on the Midwest and Northeast markets, the
   elimination of inter-regional transportation "bottlenecks," the
   growing importance of hubs and market centers, the continued
   unbundling of LDC "merchant" (or gas sales or resales) functions from
   LDC delivery services, and the "de-contracting" of long-term firm
   transportation and storage contracts currently held by gas utilities),
   the marketplace will create greater opportunities for larger, more
   geographically diversified market participants.  At the same time, the
   marketplace will place increased importance on reducing transaction
   costs to enable service providers to offer services at low cost.

             Competitive Rates and Services:  The Transaction will permit
   NiSource to meet the challenges of the increasingly competitive
   environment in the utility industry more effectively than either it or
   Columbia would alone.  The Transaction also will create financial and
   operational benefits for customers in the form of lower rates and
   better services over the long-term.  The Transaction will be presented
   to or subject to the approval of the relevant state public service
   commissions.  Those regulatory bodies will address the Transaction in
   the context of its effect on rates and service in each jurisdiction
   and NiSource will demonstrate the benefits of the Transaction in the
   process of obtaining approvals.


                                     47

             Increased Size and Stability:  Shareholders will benefit
   over the long-term from the greater financial strength and financial
   flexibility which NiSource will obtain.  NiSource will be better able
   to take advantage of future strategic opportunities and to reduce its
   exposure to changes in economic conditions in any particular segment
   of its business.

             Diversification of Service Territory:  The combined service
   territories of NiSource and Columbia will be larger and more
   geographically diverse than the independent service territories of
   each company, reducing the combined company's exposure to changes in
   economic, competitive or climatic conditions in any given sector of
   the combined service territory relative to the exposure NiSource and
   Columbia now face.

             Coordination of Diversification Programs:  NiSource and
   Columbia each have complementary unregulated businesses, and NiSource,
   as a stronger financial entity after the Transaction, should be able
   to manage and pursue these unregulated businesses more efficiently and
   effectively as a result of access to lower-cost capital and
   efficiencies achievable through greater size.

             Complementary Operational Functions:  The combination of
   NiSource and Columbia will allow NiSource after the Transaction to
   offer customers a more complete menu of service options and a better
   operational balance.  Combining Columbia's natural gas-related
   businesses with NiSource's electric expertise and operations, will
   enhance the range and quality of product offerings and services that
   can be offered to Columbia's customers.  The combined companies will
   also be better positioned to manage the fluctuating weather-related
   load profiles of their gas distribution utilities.

             Although some of the anticipated economies and efficiencies
   will be fully realizable only on a long-term basis and some of the
   potential benefits cannot be precisely estimated, they are properly
   considered in determining whether the standards of Section 10(c)(2)
   have been met.  SEE AMERICAN ELEC. POWER CO., HCAR No. 20633 (July 21,
   1978); CENTERIOR ENERGY CORP., HCAR No. 24073, 1986 SEC LEXIS 1655 at
   *18 (Apr. 29, 1986) ("[S]pecific dollar forecasts of future savings
   are not necessarily required; a demonstrated potential for economies
   will suffice even when these are not precisely quantifiable.")
   (footnote omitted).  SEE ALSO ENERGY EAST CORP., HCAR No. 26976 (Feb.
   12, 1999) (authorizing acquisition based on strategic benefits and
   potential but presently unquantifiable savings).  There is no
   requirement in Section 10(c)(2) that the specific dollar estimates of
   future savings be large in relation to the gross revenues of the
   companies involved.  SEE AMERICAN NATURAL GAS CO., HCAR No. 15620
   (Dec. 12, 1966).

             NiSource is continuing to analyze potential cost savings
   resulting from the Transaction.  Details will be filed by amendment to
   this Application/Declaration.
                                     48

             ii.  Integrated Gas Utility System

             Under Section 10(c)(2), the Commission must affirmatively
   find that the acquisition of Columbia by NiSource "will serve the
   public interest by tending towards the economical and the efficient
   development of an integrated public-utility system."  15 U.S.C.
   Section 79j(c)(2).  An "integrated public-utility system" is defined
   in Section 2(a)(29), 15 U.S.C. Section 79j(c)(2) to mean:

             (B)  As applied to gas utility companies, a system
        consisting of one or more gas utility companies which are so
        located and related that substantial economies may be effectuated
        by being operated as a single coordinated system confined in its
        operations to a single area or region, in one or more States, not
        so large as to impair (considering the state of the art and the
        area or region affected) the advantages of localized management,
        efficient operation, and the effectiveness of regulation;
        PROVIDED, That gas utility companies deriving natural gas from a
        common source of supply may be deemed to be included in a single
        area or region.<22>

             The combination of Columbia's gas utility operations with
   the NiSource gas utility operations will yield an integrated gas-
   utility system within the meaning of Section 2(a)(29)(B) of the Act.
   Indeed, because Columbia's gas distribution properties form a bridge
   between the Midwest and the mid-Atlantic and northeast regions,
   bringing NiSource's and Columbia's gas distribution operations
   together will forge even more substantial links between NiSource's
   Midwestern gas utility operations and its New England operations than
   the links that this Commission noted in 1999 in approving NiSource's
   acquisition of Bay State.

             Single Area Or Region:  The gas utility system resulting
   from the Transaction will include eight gas utilities located in the
   contiguous states of Indiana, Kentucky, Ohio, Pennsylvania, Virginia
   and Maryland and two gas utilities located in the contiguous states of
   Massachusetts, New Hampshire and Maine.  The utilities located in
   contiguous states will be effectively interconnected by affiliated and
   non-affiliated interstate pipelines and storage.  The two groups of
   contiguous utilities will likewise be capable of effective integration
   through the coordinated use of pipeline and storage capacity and
   supply sources they have in common.

   _______________

   <22>     Unlike the definition of an "integrated electric utility
   system" in Section 2(a)(29)(A) of the Act, physical interconnection of
   the component parts of a gas utility system is not required.  Further,
   the Commission has previously recognized that "integrated or
   coordinated operations of a gas system under the Act may exist in the
   absence of [physical] interconnection."  AMERICAN NATURAL GAS CO.,
   HCAR No. 15620, 1966 SEC LEXIS 469 at *11 n.5 (Dec. 12, 1966).

                                     49

             Section 2(a)(29)(B) specifically contemplates that "gas
   utility companies deriving natural gas from a common source of supply
   may be deemed to be included in a single area or region."  15 U.S.C.
   Section 79b(a)(29)(B).  Moreover, in considering whether an "area or
   region" is so large as to impair "the advantages of localized
   management, efficient operation, and the effectiveness of regulation,"
   the Commission must consider the "state of the art" in the industry.
   ID.

             The Commission's prior decisions establish that separation
   between the states served is not determinative as to whether utility
   operations constitute an integrated public utility system.  SEE MCN
   CORP., HCAR No. 26576 (Sept. 17, 1996) (approving acquisition of an
   interest in a gas-utility company by an exempt gas-utility holding
   company whose service area is located more than 500 miles distant in a
   non-adjoining state); SEMPRA ENERGY, HCAR No. 26971 (Feb. 1, 1999)
   (approving natural gas utility operations in California and North
   Carolina as a single integrated public-utility system).  The
   integration of NiSource's Massachusetts, New Hampshire and Maine gas
   utility operations and its Indiana gas utility operations has already
   been established.  This was an essential finding in the Commission
   order approving NIPSCO's acquisition of Bay State.  NIPSCO INDUS.,
   INC., HCAR 26975 (Feb. 10, 1999).  With the exception of NiSource's
   New England operations the gas distribution operations of Columbia and
   NiSource are in contiguous states and, given their location and
   reliance on many of the same interstate pipelines, are readily
   susceptible to being operated as an integrated system.

             Common Source Of Supply:  Historically, in determining
   whether two distant gas companies share a "common source of supply,"
   the Commission has placed primary importance on whether the gas supply
   of the two companies is derived from the same gas producing areas (or
   basins), recognizing that the most significant economies and
   efficiencies that two gas utilities can achieve is through the
   coordination and management of gas supply.  The Commission has also
   considered whether the two entities are served by a common pipeline.
   Further, the Commission has found an integrated system to exist where
   two entities purchase their gas from different pipelines which
   originate in the same gas producing area and/or interconnect at
   various points along the transportation route. <23>

             The NiSource and Columbia gas utility systems will
   functionally perform as a coordinated system.  They now purchase gas
   from common sources of supply (including the onshore and offshore
   Texas and Louisiana producing region and the mid-Continent region) and
   will continue to do so.  Moreover, they will each have enhanced
   opportunities to increase their respective purchases of Western
   Canadian Sedimentary Basin gas sourced through the Chicago market

   center.  The NiSource and Columbia gas utility systems currently hold
   firm transportation service agreements on a number of the same
   interstate pipelines, including ANR, Panhandle Eastern, Tennessee Gas,
   Texas Gas, Texas Eastern and Transco.  The NiSource Midwestern gas
   utilities are physically linked through Crossroads' interconnections
   with Columbia Transmission, Trunkline and Panhandle Eastern with a
   transmission system (Columbia Transmission) that serves each of the
   Columbia gas distribution utilities.  The Columbia and NiSource gas
   distribution utilities also make use of other, regional pipelines to
   transport and deliver Canadian and Appalachian-sourced supplies,
   including Crossroads, National Fuel and CNG.  In addition, gas
   purchased by the unregulated marketing affiliates of each of NiSource
   and Columbia has been transported by NiSource subsidiary Crossroads
   for further delivery to utility customers served by NiSource's and
   Columbia's gas public utilities located in Indiana, Ohio and
   Pennsylvania. These links, and the increased presence the combined
   NiSource and Columbia utilities will have at Midwestern, mid-Atlantic
   and northeastern market centers, will facilitate coordinated
   management of interstate transportation and gas supplies.  Additional
   efficiencies and arbitrage opportunities will be realized over time
   through the combined companies' use of a single data management system
   to record gas transaction data.

             Trading "hubs" and market centers have rapidly grown in
   importance as a result of the construction of new pipeline capacity,
   the unbundling of interstate transportation from gas sales, the
   development of high deliverability salt cavern storage gas storage
   facilities and local distribution companies' "de-contracting" of firm
   pipeline capacity.  Trading hubs and market centers now provide market
   participants with access to gas supplies sourced from multiple, widely
   separated producing areas, by way of any number of interconnected
   interstate pipeline facilities at a manageable number of common
   geographic points.  These hubs and centers have contributed to the
   establishment of a fully integrated, competitive marketplace in which
   real-time pricing is available.<24>

             Using many of the same hubs and market centers, the NiSource
   and Columbia gas public utilities and their affiliates have daily
   opportunities to coordinate and manage their gas supply and
   transportation portfolios.  These opportunities will increase in
   number and scope as a consequence of the combination of the two groups
   of distribution companies.  The result will be increased efficiency
   and economy, and a greatly enhanced ability to support retail

   _______________

   <24>     As a result of the evolution of an integrated, competitive
   marketplace for both supply and transportation, the duration of
   contracts has shortened considerably.  In fact, local distribution
   companies now purchase significant amounts of their gas supply under
   short-term (E.G., daily) arrangements.  Some local distribution
   companies are as a corollary reducing their exposure under long-term
   firm transportation contracts (a process known as "de-contracting").

                                     51

   unbundling and performance-based ratemaking initiatives that will
   benefit the distribution companies' customers and their shareholders
   alike.  So, for example, gas purchased, sold or exchanged at the
   Lebanon Hub in Ohio can satisfy the gas distribution utility
   requirements of NiSource's Indiana gas utility subsidiaries,
   Columbia's gas distribution companies in the mid-Atlantic region and
   NiSource's gas distribution subsidiaries in New England.  By utilizing
   existing NiSource capacity and deliverability entitlements at the Egan
   Storage hub in Louisiana, the various NiSource and Columbia
   distribution utilities can achieve additional pricing certainty and
   operational flexibility, and can share these benefits through their
   common use of the Columbia Gulf/Columbia Transmission, ANR,
   Trunkline/Panhandle Eastern, Tennessee Gas and Texas Gas systems.
   Moreover, upon the completion of various proposed pipelines and/or
   pipeline expansions from the Chicago area to the eastern U.S. markets,
   the combined NiSource and Columbia distribution companies, either
   directly or through interstate pipeline affiliates, will have direct
   access to all gas supplies entering the Chicago market center.

             Industry studies indicate that the importation of low-cost
   western Canadian gas is reshaping the dynamics of gas supply in
   certain U.S. markets (in particular the Midwest and
   Northeast).<25>  Those studies conclude that, in the future, there
   will be much more of a west-to-east flow of gas to the Northeast.
   With the expansion of import capacity into the Chicago area, it is
   projected that the Midwest will experience an excess supply situation.
   This expectation has lead to various regional pipeline expansion
   proposals between the Midwest and Northeast, all of which are designed
   to move Midwest supplies to the supply-constrained Northeast
   markets.<26>  As a consequence, it is likely that the Midwest
   itself will become an important supply region for gas moving to the
   Northeast.  The combination of the NiSource and Columbia systems will
   produce a single, integrated gas utility system, whose components will
   be linked by affiliated and third party interstate pipelines, in an
   essentially unbroken chain extending from the northwestern corner of
   Indiana through the Midwest to the mid-Atlantic region and east into
   New England.

             State Of The Art:  Any determination of the appropriate size
   of the area or region calls for consideration of the "state of the
   art" in the gas industry.  This "state of the art" continues to evolve
   and change, primarily as a result of decontrol of wellhead prices, the
   continuing development of an integrated national gas transportation
   network, the emergence of natural gas marketers and brokers, and the
   "un-bundling" of the commodity and transportation functions of
   pipelines in response to various FERC initiatives.<27>  Of
   particular importance has been the formation of a national network of
   trading hubs at locations where interstate pipelines
   intersect.<28>  Today, trading activity conducted at hubs plays an
   increasingly vital role in the overall management of the assets in a
   gas portfolio (supply, transportation and storage).  The hubs
   frequently utilized as trading centers for gas supply destined for the
   Midwest, mid-Atlantic, and New England markets are listed below:

   <27>     The Commission has taken notice of the regulatory and
   technological changes that have reshaped the natural gas industry over
   the past two decades.  SEE 1995 Report, at 29-38.  The 1995 Report
   recommended that the Commission "interpret the single area or region'
   requirement [of Section 2(a)(29)] flexibly, recognizing technical
   advances, consistent with the purposes and provisions of the Act."
   ID. at 73.

   <28>     The development of trading hubs and market centers was the
   direct outgrowth of FERC's Order 636, which required interstate
   pipelines to separate, or "un-bundle," the commodity and
   transportation and storage functions of the interstate pipelines.  SEE
   REGULATION OF NATURAL GAS PIPELINES AFTER PARTIAL WELLHEAD DECONTROL,
   Order No. 636, 57 Fed. Reg. 13,267 (Apr. 16, 1992).  FERC has promoted
   the development of trading hubs as a means and location for providing
   services that customers of the interstate pipelines (I.E., shippers)
   need in order to manage their portfolios of gas supply,
   transportation, and storage, all of which can now be contracted
   separately.  Today, there are more than 39 trading centers and market
   hubs in operation.  For a comprehensive analysis of the role of market
   hubs and trading centers, see ENERGY INFORMATION ADMINISTRATION,
   NATURAL GAS 1996: ISSUES AND TRENDS, DOE/EIA-0560(96).

             Trading hubs (including all of those listed above)
   essentially function as physical transfer points between intersecting
   pipelines, where shippers (I.E., buyers and sellers) and traders can
   sell, exchange or trade gas or pipeline capacity or redirect
   deliveries to a different pipeline.  Further, various types of
   unbundled services are typically available at trading hubs, such as
   temporary storage, parking and loaning of gas, and balancing.  Because
   of the role played today by market hubs and market centers,
   coordination of the operations of two or more geographically
   diversified gas companies is no longer dependent solely upon having
   contractual capacity on the same interstate pipelines, so long as the
   companies both have access to one or more common trading hubs.

             Importantly, trading hubs now allow gas distribution
   companies operating in a much larger area or region of the country to
   realize operating economies and efficiencies from coordinated
   operation that were once achievable only by contiguous or nearly
   contiguous gas companies supplied by the same interstate pipelines.
   In fact, as discussed below, the opportunities to achieve operating
   economies may be even greater where companies seeking to combine have
   significantly different load profiles (E.G., non-coincident seasonal

                                     54

   peaks, a substantially different customer mix, etc.).<29>  This
   logic applies with even greater force where, as in this case, one of
   the companies (NiSource) has gas distribution operations in a major
   gas market center (the Chicago market center) and in a region which
   industry forecasts expect to experience significant growth in demand
   (the U.S. northeast) while others (the Columbia distribution
   utilities) are located between the market center and the high growth
   area.

             Because the NiSource and Columbia distribution utilities
   share access through their respective pipeline transporters to several
   industry-recognized market and supply-area hubs, they will have the
   ability physically to coordinate and manage their portfolios of
   supply, transportation and storage. One example of this is the
   potential for coordination using the Egan Storage facility and common
   interconnecting pipelines described above.  NiSource and Columbia also
   have access to the Henry Hub in southern Louisiana via capacity on the
   ANR, NGPL, Trunkline, Texas Gas, Transco and Columbia Gulf pipelines.
   The Henry Hub is the recognized center for natural gas futures trading
   in the U.S.  Through nine interstate and four intrastate pipeline
   interconnections, market participants such as Columbia and NiSource's
   gas  distribution utilities and other affiliates can physically
   support, if necessary, the utilization of financial derivatives as a
   means of managing price volatility.

             Moreover, through interconnections via Crossroads and third
   party pipelines between NiSource's midwestern gas distribution
   utilities and the Columbia Transmission system, both NiSource's and
   Columbia's gas public utilities will benefit from the ability to share
   and optimize storage capacity each company owns or has under contract.
   As previously stated, NiSource has access to "high deliverability"
   salt dome storage capacity held by Northern Indiana in Texas and
   Louisiana, while Columbia's distribution companies have contractual
   rights to use the substantial storage capacity operated by Columbia
   Transmission.  Similar opportunities to optimize contractual
   entitlements to capacity and deliverability exist with respect to the
   LNG storage capacity which the NiSource and Columbia distribution
   companies own or have under contract.  Shared access to the various
   classes of gas storage facilities would provide NiSource and Columbia
   with an important gas balancing capability, which will allow the
   combined companies to manage fluctuating weather-related load profiles
   on their various distribution systems.

             Finally, by making enhanced use of the Crossroads/Columbia
   Transmission interconnect, Columbia's distribution companies would
   gain direct access to the Chicago market center.  Such access will be
   an important gas supply resource and a vital risk management tool as

   _______________

   <29>     For example, due to the normal effects of the west-to-east
   "weather lag," Bay State's demand pattern tends to follow the NiSource
   demand pattern by, on average, 24 to 48 hours.

                                     55

   the Chicago market center becomes an increasingly important source of
   gas for all eastern U.S. markets.

             No Impairment:  The resulting integrated gas system to be
   formed by the combination of Columbia's gas properties with those of
   NiSource will not be "so large as to impair (considering the state of
   the art and the area or region affected) the advantages of localized
   management, efficient operation, and the effectiveness of regulation."

             In this case, the separate corporate identity and local
   headquarters of each of Columbia's five natural gas public utility
   subsidiaries will be maintained.  Further, following the Transaction,
   each of the Columbia and NiSource public utilities will remain subject
   to regulation as to rates, service, and other matters by the
   regulatory agencies in each of the states in which they provide public
   utility services.

        4.   Section 10(f)   State Laws and Section 11

             Section 10(f) of the Act provides that:

        The Commission shall not approve any acquisition as to which
        an application is made under this section unless it appears
        to the satisfaction of the Commission that such State laws
        as may apply in respect to such acquisition have been
        complied with, except where the Commission finds that
        compliance with such State laws would be detrimental to the
        carrying out of the provisions of section 11.

   15 U.S.C. Section 79k(f).  As described in Item 4 of this
   Application/Declaration, NiSource and Acquisition Corp. will comply
   with all applicable state laws related to the Transaction.

   B.   INTRA-SYSTEM PROVISION OF SERVICES

             In addition to requesting that the Commission find that
   Corporate Services meets the organizational and operational
   requirements of Section 13(b) for subsidiary service companies,
   NiSource also requests exemptions from the provisions of Rules 90 and
   91, and the at-cost requirements contained therein, in connection with
   services provided by Corporate Services to any affiliated qualifying
   facilities ("QFs"), independent power producers ("IPPs"), exempt
   wholesale generators ("EWGs") and foreign utility companies ("FUCOs").
   As described in more detail below, NiSource believes these exemptions
   will help these companies compete more effectively for the provision
   of services to such entities, which are either majority owned by
   unaffiliated third parties (eliminating the potential for abusive
   affiliate transactions) or are otherwise adequately regulated with
   respect to affiliated transactions and do not otherwise present the
   concerns for which the Commission developed its at-cost requirements.
   The Commission has granted similar exemptions to existing registered
   holding companies.  All other services provided by NiSource system

                                     56

   companies to other NiSource system companies will be in accordance
   with the requirements of Section 13 of the Act, unless otherwise
   exempted by the Commission or the rules promulgated under the Act.

             1.   Corporate Services

             As described above, although NiSource may maintain Columbia
   Energy Services as a separate service company during a transitional
   period, NiSource currently intends to combine Columbia Energy Services
   with NiSource's corporate service company.  Corporate Services will
   provide Northern Indiana, Kokomo Gas, NIFL, Columbia Ohio, Columbia
   Pennsylvania, Columbia Virginia, Columbia Kentucky and Columbia
   Maryland, pursuant to an appropriate service agreement, with a variety
   of administrative, management and support services, including services
   relating to planning, transportation, materials management, facilities
   and real estate, accounting, budgeting and financial forecasting,
   finance and treasury, rates and regulation, legal, internal audit,
   corporate communications, environmental, fuel procurement, corporate
   planning, investor relations, human resources, marketing and customer
   services, information systems, information technology management,
   general administrative and executive management services and other
   services.  In accordance with the service agreement, any services
   provided by Corporate Services will be directly assigned, distributed
   or allocated by activity, project, program, work order or other
   appropriate basis.  To accomplish this, employees of Corporate
   Services will record transactions utilizing the existing data and
   accounting systems of each client company.  Costs of Corporate
   Services will be accumulated in accounts and directly assigned,
   distributed and allocated to the appropriate client company in
   accordance with the guidelines set forth in the service agreement.
   NiSource is currently developing the system and procedures necessary
   to implement the Commission's rules.

             Corporate Services' accounting and cost allocation methods
   and procedures are structured so as to comply with the Commission's
   requirements for service companies in registered holding company
   systems.  Its billing system uses or will use the "Uniform System of
   Accounts for Mutual Service Companies and Subsidiary Service
   Companies" established by the Commission for service companies of
   registered holding company systems.

             As compensation, the service agreement would provide that
   the client company will pay to Corporate Services all costs which
   reasonably can be identified and related to particular services
   performed by Corporate Services.  Where more than one client company
   has received benefits from a service performed by Corporate Services,
   costs will be directly assigned, distributed or allocated, between or
   among such client companies on a basis reasonably related to the
   services performed.  Therefore, charges for all services provided by
   Corporate Services to affiliated utility companies will be on an "at
   cost" basis in accordance with Rules 90 and 91 of the Act.

                                     57

             NiSource has not yet determined whether Corporate Services
   will perform services to NiSource's and Columbia's non-utility
   subsidiaries under the service agreement or a separate non-utility
   service agreement.  Nevertheless, services provided by Corporate
   Services to non-utility affiliates will also be charged on an "at
   cost" basis in accordance with Rules 90 and 91 of the Act, except as
   authorized by the Commission to be provided at fair market value.

             Section 13(b) of the Act allows the Commission to exempt
   transactions, by rule, regulation or order, from the provisions of
   Section 13(b) and the rules promulgated thereunder if such
   transactions:

             (1) are with any associate company which does not
             derive, directly or indirectly, any material part of
             its income from sources within the United States and
             which is not a public utility company operating within
             the United States or (2) involve special or unusual
             circumstances or are not in the ordinary course of
             business.

   15 U.S.C. Section 79m(b).  The Commission grants such an exemption to
   permit non-utility subsidiaries of a registered holding company to
   provide certain services to FUCOs, EWGs, IPPs and QFs at market-based
   rates.<30>  In addition, in the 1995 Report, the Division
   recommended that "the SEC should also issue exemptive orders under
   Section 13 allowing more nonutility subsidiaries to charge market
   rates to nonutility affiliates."<31>  The Commission's primary
   concern under Section 13 is to protect utility subsidiaries in a
   registered holding company system from abusive cross-subsidization
   transactions with non-utility affiliates. Exemptions from Rules 90 and
   91 for transactions solely between non-utility affiliates will not
   interfere with the financial integrity of the utility affiliates, but
   will benefit the holding company system by permitting it to offer
   competitively priced services based on market considerations.
   Therefore, Corporate Services requests that the Commission grant an
   exemption from the provisions of Rules 90 and 91, and the at-cost
   requirement contained therein, in order for Corporate Services to
   provide services to associate FUCOs, EWGs, IPPs and QFs.  No services
   will be provided at market-based rates to a FUCO, EWG, IPP or QF
   selling electricity to Northern Indiana unless authorized by the Act
   or the Commission.

             No change in the organization of Corporate Services, the
   type and character of the client companies, the methodology for

   allocating costs to client companies, or the scope and character of
   the services to be rendered subject to Section 13 of the Act, or any
   rule promulgated by the Commission thereunder, shall be made unless
   and until Corporate Services shall have first provided the Commission
   with written notice of the proposed change at least 60 days prior to
   the proposed effective date.  If, upon the receipt of such notice, the
   Commission notifies Corporate Services within the 60-day period that a
   question exists as to whether the proposed change is consistent with
   the provisions of Section 13 of the Act, or of any rule promulgated by
   the Commission thereunder, then the proposed change will not become
   effective unless and until Corporate Services has filed with the
   Commission an appropriate declaration regarding the proposed change
   and the Commission has permitted the declaration to become effective.

             NiSource submits that its service agreements will be
   structured in a manner which complies with Section 13 of the Act and
   the Commission's rules and regulations thereunder and requests the
   Commission's approval of these agreements.

             Rule 88 provides that "[a] finding by the Commission that a
   subsidiary company of a registered holding company . . . is so
   organized and conducted or to be conducted, as to meet the
   requirements of section 13(b) of the Act with respect to reasonable
   assurance of efficient and economical performance of services or
   construction or sale of goods for the benefit of associate companies,
   at cost fairly and equitably allocated among them (or as permitted by
   [Rule 90]), will be made only pursuant to a declaration filed with the
   Commission on Form U-13-1, as specified" in the instructions for that
   form, by such company or the persons proposing to organize it.  17
   C.F.R. Section 250.88.  Notwithstanding the language of Rule 88, the
   Commission has recently made findings under Section 13(b) based on
   information set forth in an Application/Declaration or Form U-1,
   without requiring the formal filing of a Form U-13-1.  SEE CINERGY
   CORP., HCAR No. 26146 (Oct. 21, 1994); UNITIL CORP., HCAR No. 25524
   (April 24, 1992).  In this Application/Declaration, NiSource submits
   the same information as would be submitted in a Form U-13-1.

             Accordingly, NiSource submits to the Commission that the
   filing of a Form U-13-1 is unnecessary, or, alternatively, that this
   Application/Declaration should be deemed to constitute the filing of
   Form U-13-1 for purposes of Rule 88.
