BUSINESS

5. (a)

Business
NiSource Inc. ("NiSource") is an energy holding company that
provides natural gas, electricity and other products and services
to 3.6 million customers located within the energy corridor that
runs from the Gulf Coast through the Midwest to New England.
NiSource, organized as an Indiana holding company in 1987 under
the name of NIPSCO Industries, Inc., changed its name to NiSource
Inc. on April 14, 1999. In connection with the acquisition of
Columbia Energy Group ("Columbia") on November 1, 2000, as
discussed below, NiSource became a Delaware corporation. NiSource
is a registered holding company under the Public Utility Holding
Company Act of 1935, as amended (the "Act"), and derives
substantially all its revenues and earnings from the operating
results of its subsidiaries.

On November 1, 2000, NiSource completed its acquisition of
Columbia for an aggregate consideration of approximately $6
billion, with 30% of the consideration paid in common stock with
the remaining 70% paid in cash and Stock Appreciation Income
Linked SecuritiesSM ("SAILSSM") which are units each consisting
of a zero coupon debt security coupled with a forward equity
contract in NiSource shares. NiSource also assumed approximately
$2 billion in Columbia debt. As a result of the acquisition,
NiSource is the largest natural gas distribution company
operating east of the Rocky Mountains, as measured by number of
customers. NiSource's principal subsidiaries include Columbia, a
vertically-integrated natural gas distribution, transmission,
storage and exploration and production holding company whose
subsidiaries provide service to customers in the Midwest, the
Mid-Atlantic and the Northeast; and Northern Indiana Public
Service Company ("Northern Indiana"), a vertically-integrated gas
and electric company providing service to customers in northern
Indiana; and Bay State Gas Company ("Bay State"), a natural gas
distribution company serving customers in New England.

NiSource's primary business segments are: gas distribution;
electric operations; gas transmission and storage; exploration
and production; energy marketing; and other products and
services.

Gas Distribution
NiSource's natural gas distribution operations in total serve
more than 3.2 million customers in 9 states and operate over
54,048 miles of pipeline. Through its wholly-owned subsidiary,
Columbia, NiSource owns five distribution subsidiaries that
provide natural gas to approximately 2.1 million residential,
commercial and industrial customers in Ohio, Pennsylvania,
Virginia, Kentucky and Maryland. NiSource also distributes
natural gas to approximately 751,000 customers in northern
Indiana through three subsidiaries: Northern Indiana, Kokomo Gas
and Fuel Company and Northern Indiana Fuel and Light Company,
Inc. Additionally, NiSource's subsidiaries, Bay State and
Northern Utilities, Inc., distribute natural gas to more than
320,000 customers in areas of Massachusetts, Maine and New
Hampshire. The distribution subsidiaries pursue initiatives that
give residential and small commercial customers the opportunity
to choose their natural gas suppliers and to use the distribution
subsidiaries for transportation service. This ability to choose a
supplier was previously limited to larger commercial and
industrial customers.

Electric Operations
Through its subsidiary Northern Indiana, NiSource generates and
distributes electricity to approximately 430,000 customers in 21
counties in the northern part of Indiana. Northern Indiana owns
and operates four coal-fired electric generating stations with a
net capability of 3,179 megawatts, four gas-fired combustion
turbine generating units with a net capability of 203 megawatts
and two hydroelectric generating plants with a net capability of

10 megawatts. In total these facilities provide for a total
system net capability of 3,392 megawatts. Northern Indiana is
interconnected with five neighboring electric utilities. During
the year ended December 31, 2000, Northern Indiana generated
94.8% and purchased 5.2% of its electric requirements.

Gas Transmission and Storage
NiSource's gas transmission and storage subsidiaries own and
operate approximately 16,500 miles of interstate pipelines and
operate one of the nation's largest underground natural gas
storage systems. Through its subsidiaries, Columbia Gas
Transmission Corporation ("Columbia Transmission") and Columbia
Gulf Transmission Company ("Columbia Gulf"), it owns and operates
an interstate pipeline network extending from offshore in the
Gulf of Mexico to Lake Erie, New York, and the eastern seaboard.
Together, Columbia Transmission and Columbia Gulf serve customers
in 16 northeastern, mid-Atlantic, mid-western and southern states
and the District of Columbia. The gas transmission and storage
subsidiaries are engaged in several projects that will expand its
service territory and throughput. The largest such project is the
proposed 442-mile Millennium Pipeline Project in which Columbia
Transmission is participating. As proposed, the project will
transport approximately 700 Bcf of natural gas per day from the
Lake Erie region to eastern markets. This project is currently
awaiting approval by the Federal Energy Regulatory Commission
("FERC").

Exploration and Production
NiSource's Columbia Energy Resources, Inc. ("Columbia
Resources"), is an exploration and production subsidiary that
explores for, develops, gathers and produces natural gas and oil
in Appalachia and Canada. As of December 31, 2000, Columbia
Resources has net proven gas and oil reserve holdings of 1.1
trillion cubic feet equivalent and owns and operates 6,200 miles
of gathering pipelines.

Energy Marketing
NiSource provides non-regulated energy marketing and services
through its subsidiary EnergyUSA, Inc. and its subsidiary
EnergyUSA-TPC Corp. ("TPC") These operations include energy
marketing and asset management services to LDCs, wholesale,
commercial and industrial customers. TPC primarily provides
energy-related asset management and asset portfolio replacement
opportunities for LDCs and fuel requirement services for electric
utilities, independent power producers and cogeneration
facilities. TPC also provides natural gas sales and management
services to industrial and commercial customers, engages in
natural gas marketing activities and provides gas supply to
Northern Indiana, Kokomo Gas and Fuel Company and Northern

Indiana Fuel and Light Company, Inc. under spot and/or term
contracts.

Other Products and Services
NiSource develops power projects through its subsidiary, Primary
Energy, Inc., which works with industrial customers in managing
the engineering, construction, operation and maintenance of
"inside the fence" cogeneration plants that provide
cost-effective, long-term sources of energy for energy-intensive
facilities. NiSource has also invested in a number of distributed
generation technologies including fuel cells and microturbine
ventures. NiSource is also building a dark-fiber optics
telecommunications network primarily along its pipeline
rights-of-way between New York and Washington D.C. NiSource is
pursuing strategic alternatives for its telecommunications
network, has recently exited the pipeline construction business
and is in the process of selling the line locating and marking
business.

Divestiture of Non-Core Assets
In connection with the Columbia acquisition, NiSource sold or is
divesting certain businesses judged to be non-core to the
company's energy strategy. Subsequent to the announcement of the
Columbia acquisition, NiSource sold Market Hub Partners L.P., a
company that owns and operates salt cavern gas storage facilities
in Texas and Louisiana. Columbia completed the divestiture of its
interest in the Cove Point LNG facilities. In February 2001,
NiSource settled a lawsuit related to MHP operations for an
immaterial amount. NiSource recently completed the sale of its
pipeline construction subsidiary and Columbia electric generation
businesses. NiSource also recently sold substantially all of its
petroleum businesses. On January 31, 2001, NiSource announced a
definitive agreement to sell the stock and assets of Columbia
Propane Corporation to AmeriGas Partners, L.P. (AmeriGas) for
approximately $208 million, including $53 million of AmeriGas
partnership common units. Through its subsidiary IWC Resources
Corporation, NiSource supplies water to residential, commercial
and industrial customers and for fire protection service in
Indianapolis, Indiana and surrounding areas. As part of the
Securities and Exchange Commission's order approving the Columbia
merger, NiSource has been ordered to divest its water utility
business by November 2003. As a result of management's formal
divestiture plan, the water utility business is reported as
discontinued operations. NiSource is pursuing the sale of smaller
non-core businesses, including its underground utility locating
and marking business.

Further information regarding the general business of NiSource
and its subsidiaries may be found in the Merger U-1 (File No.
70-9551) filed as Exhibit F-4 hereto and incorporated by
reference herein. In addition, a more detailed business

description of NiSource and its subsidiaries may be found in the
following documents which are hereby incorporated by reference
herein: the Annual Reports of NiSource Inc. (File No. 1-16189)
filed as Exhibit F-1 hereto, Northern Indiana (File No. 1-4125)
filed as Exhibit F-2 and Columbia Energy Group (File No. 1-01098)
filed as Exhibit F-3 hereto, all on Form 10-K for the year ended
December 31, 2000 as contained in Item 1 thereof.

(b) Any substantial changes which may have occurred in the general
character of the business of such companies during the preceding five
years.

The regulatory frameworks applicable to NiSource's regulated
operations, at both the state and federal levels, are undergoing
fundamental changes. These changes have impacted and will
continue to have an impact on NiSource's operations, structure
and profitability. At the same time, competition within the gas
and electric industries will create opportunities to compete for
new customers and revenues. Management continually seeks new ways
to be more competitive and profitable in this changing
environment, including partnering on energy projects with major
industrial customers, converting some of its generating units to
allow use of lower cost low sulfur coal, providing its gas
customers with increased customer choice for new products and
services, acquiring companies that will provide improved
economies of scale and efficiencies and developing new
energy-related products for residential, commercial and
industrial customers. In addition, NiSource is in the process of
divesting certain businesses judged to be non-core to the
company's energy strategy.

Open access to natural gas supplies over interstate pipelines and
the deregulation of the commodity price of gas has led to
tremendous change in the energy markets, which continue to
evolve. During the past few years, LDC customers and marketers
began to purchase gas directly from producers and marketers and
an open competitive market for gas supplies emerged. This
separation or "unbundling" of the transportation and other
services offered by pipelines and LDCs allows customers to select
the service they want independent from the purchase of the
commodity. NiSource's gas distribution subsidiaries are involved
in programs that provide residential customers the opportunity to
purchase their natural gas requirements from third parties and
use the NiSource gas distribution subsidiaries for transportation
services only. At the same time that the natural gas markets are
evolving, the markets for competing energy sources are also
changing.

In 1996, the FERC ordered that all public utilities owning,
controlling or operating electric transmission lines to file
non-discriminatory open-access tariffs and offer wholesale
electricity suppliers and marketers the same transmission service
they provide themselves. In 1997, FERC accepted for filing

Northern Indiana's open-access transmission tariff. In December
1999, FERC issued a final rule addressing the formation and
operation of Regional Transmission Organizations. The rule was
intended to eliminate pricing inequities in the provision of
wholesale transmission service. In October 2000, NiSource filed
with the FERC indicating that it is committed to joining an RTO
and in February 2001, Northern Indiana became a member of the
Alliance RTO in formation. The Alliance RTO expects to be fully
operational by FERC's December 15, 2001, deadline. Although
wholesale customers currently represent a small portion of
Northern Indiana's electricity sales, it intends to continue its
efforts to retain and add wholesale customers by offering
competitive rates and also intends to expand the customer base
for which it provides transmission services.

In connection with the Columbia acquisition, NiSource sold or is
divesting certain businesses judged to be non-core to the
company's energy strategy. Subsequent to the announcement of the
Columbia acquisition, NiSource sold Market Hub Partners L.P., a
company that owns and operates salt cavern gas storage facilities
in Texas and Louisiana. Columbia completed the divestiture of its
interest in the Cove Point LNG facilities. In February 2001,
NiSource settled a lawsuit related to MHP operations for an
immaterial amount. NiSource recently completed the sale of its
pipeline construction subsidiary and Columbia electric generation
businesses. NiSource also recently sold substantially all of its
petroleum businesses. On January 31, 2001, NiSource announced a
definitive agreement to sell the stock and assets of Columbia
Propane Corporation to AmeriGas Partners, L.P. (AmeriGas) for
approximately $208 million, including $53 million of AmeriGas
partnership common units. Through its subsidiary IWC Resources
Corporation, NiSource supplies water to residential, commercial
and industrial customers and for fire protection service in
Indianapolis, Indiana and surrounding areas. As part of the
Securities and Exchange Commission's order approving the Columbia
merger, NiSource has been ordered to divest its water utility
business by November 2003. As a result of management's formal
divestiture plan, the water utility business is reported as
discontinued operations. NiSource is pursuing the sale of smaller
non-core businesses, including its underground utility locating
and marking business.

CHARACTER OF OWNERSHIP

Substantially all of the properties of Northern Indiana are subject to
a lien of First Mortgage Indentures. The principal offices and
properties of NiSource and its subsidiaries are held in fee and are
free from other encumbrances, subject to minor exceptions, none of
which are of such a nature as to impair substantially the usefulness
of such properties. Many of the offices in various communities served
are occupied by subsidiaries of NiSource under leases. All properties
are subject to liens for taxes, assessments and undetermined charges
(if any) incidental to construction. It is NiSource's practice
regularly to pay such amounts, as and when due, unless contested in
good faith. In general, the electric lines, gas pipelines and related
facilities are located on land not owned in fee but are covered by
necessary consents of various governmental authorities or by
appropriate rights obtained from owners of private property. NiSource
does not, however, generally have specific easements from the owners
of the property adjacent to public highways over, upon or under which
its electric lines and gas pipelines are located. At the time each of
the principal properties was purchased a title search was made. In
general, no examination of titles as to rights-of-way for electric
lines, gas pipelines or related facilities was made, other than
examination, in certain cases, to verify the grantors' ownership and
the lien status thereof.

See Item 2 of the Annual Report of NiSource on Form 10-K for the year
ended December 31, 2000 (File No. 1-16189) (filed as Exhibit F-1

13. If, during the last five years, the registrant or any subsidiary
company thereof has issued, sold, or exchanged either publicly or privately
any securities having a principal amount, par, stated or declared value
exceeding $1,000,000 or exceeding an amount equal to 10% of the total
liabilities as shown by the balance sheet of issuer at the time such issue
(whichever of such sums is the lesser), give the following information with
respect to each such issue or sale:

By permission of the Staff, information required to be disclosed
pursuant to this item is not set forth herein.

AGREEMENTS FOR FUTURE DISTRIBUTION OF SECURITIES

14. (a) Summarize the terms of any existing agreement to which the
registrant of any associate or affiliate company thereof is a party or
in which any such company has a beneficial interest with respect to
future distributions of securities of the registrant or of any
subsidiary.

Certain information regarding agreements with respect to future
distribution of securities of NiSource and its subsidiaries is
set forth in the following documents, the applicable portions of
which are hereby incorporated herein by reference: Items 1.7 and
1.8 of the Application/Declaration of NiSource and Columbia on
Form U-1, as amended (File No. 70-9681) (the Financing U-1)
(filed herewith as Exhibit F-5); the Registration Statement of
NiSource on Form S-3 (File No. 333-49316) (filed herewith as
Exhibit F-6), with respect to the registration of $2.5 billion
common stock, preferred stock and debt securities and related
guarantees of debt securities and with respect to the issuance of
$300 million of senior unsecured notes having a coupon rate of
5.75% and maturity date of April 15, 2003; and the Registration
Statement of NiSource on Form S-3 (File No. 333-49330) (filed
herewith as Exhibit F-7), with respect to the registration of
11.5 million shares of common stock.

Since the closing of the NiSource's acquisition of Columbia, the
following financings have been executed by NiSource's financing
subsidiary:

1. NiSource reduced its acquisition related commercial paper
borrowings through the issuance of $2.5 billion of privately
placed notes, completed on November 10, 2000. This issuance
included $750 million of three-year notes paying a 7.5%
coupon and maturing on November 15, 2003, $750 million of
five-year notes paying a 7.625% coupon and maturing on
November 15, 2005, and $1 billion of ten-year notes paying a
7.875% coupon and maturing on November 15, 2010.
Subsequently, an additional $150 million of five-year notes
were issued, bearing a 7.625% coupon and maturing on
November 15, 2005.

2. On November 27, 2000, NiSource issued 11.5 million new
shares of NiSource common stock at an offering price of
$25.25 per share. The $280.9 million of net proceeds were
used to repay commercial paper.

3. In March 2001, NiSource arranged a new $2.5 billion
revolving credit facility with a syndicate of banks for
future working capital requirements. The new facility has
refinanced and consolidated essentially all of NiSource's
existing short-term credit facilities as discussed above,

into one credit facility, through its NiSource Finance
subsidiary.

4. On April 6, 2001, NiSource issued $300 million of senior
unsecured notes, utilizing the Company's S-3 shelf
registration, filed and declared effective in November 2000.
The notes have a coupon rate of 5.75% and mature on April
15, 2003. Proceeds from the issuance will be used to repay
commercial paper borrowings.

There are no additional financing activities expected to occur
during the next 12 months. The specific timing, execution and
choice of future security issues will be based upon actual market
conditions and cash flow needs of the companies.

(b) Describe briefly the nature of any financial interest (other than
the ownership of securities acquired as a dealer for the purpose of
resale) which any person with whom such agreement exists, has in the
registrant or in any associate company thereof.

The beneficiaries of the employee benefit plans may be deemed to
have a financial interest in the registrant or affiliated
companies thereof by virtue of their employment relationship with
the registrant or such other companies and compensation, benefit
and severance agreements and arrangements relating to such
employment.

Further information regarding employee benefit plans of NiSource
and its subsidiaries may be found in the following documents
which are hereby incorporated by reference herein: the Annual
Reports of NiSource Inc. (File No. 1-16189) filed as Exhibit F-1
hereto, Northern Indiana (File No. 1-4125) filed as Exhibit F-2,
Columbia Energy Group (File No. 1-01098) filed as Exhibit F-3
hereto, all on Form 10-K for the year ended December 31, 2000,
and NiSource's 2001 Proxy Statement, dated March 12, 2001 (File
No. 1-16189), filed as Exhibit F-8 hereto.

TWENTY LARGEST HOLDERS OF CAPITAL STOCKS

15. As of a recent date (indicating such date for each class) give the
following information with respect to the holders of each class of stock
and/or certificates of beneficial interest of the registrant:

(a) The twenty largest registered holders of common stock of
NiSource, as of its most recent dividend record date.

NiSource shares can be held by certificate, through dividend
reinvestment plans, through investment companies, and other
street name and nominee accounts. Absent an unreasonable
expenditure of time and money, Nisource has no way to determine

the number of shares held by each holder of beneficial interest.
Accordingly, NiSource is only able to provide information as to
shares registered with NiSource.

The following table sets forth NiSource's twenty largest
registered shareholders on the books as of February 25, 2001:
