PART I

ITEM 1. BUSINESS

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

Columbia Energy Group (Columbia) and its subsidiaries are primarily engaged in
natural gas transmission, natural gas distribution, and exploration for and
production of natural gas and oil. Columbia, organized under the laws of the
State of Delaware on September 30, 1926, is a registered holding company under
the Public Utility Holding Company Act of 1935 (1935 Act), as amended, and
derives substantially all of its revenues and earnings from the operating
results of its 18 direct subsidiaries.

Merger with NiSource Inc.

On November 1, 2000, NiSource Inc. (NiSource) completed the acquisition of
Columbia for an aggregate consideration of approximately $6 billion, with 30% of
the consideration paid in NiSource common stock and the remaining 70% paid in
cash and Stock Appreciation Income Linked Securities(SM), referred to as
SAILS(SM). In addition, NiSource assumed approximately $2 billion of Columbia
debt.

Presentation of Segment Information

Columbia meets the conditions specified in General Instruction I(1)(a) and (b)
to Form 10-K and is permitted to use the reduced disclosure format for
wholly-owned subsidiaries of companies, such as NiSource, that are reporting
companies under the Securities Exchange Act of 1934. Accordingly, the Narrative
and Analysis of Results of Operations is included in this report, and Columbia
has omitted from this report the information called for by Item 7 (Management's
Narrative and Analysis of Results of Operations).

Columbia operates in four segments: Distribution, Transmission and
Storage, Exploration and Production and Other.

Distribution Operations

Columbia's five distribution subsidiaries provide natural gas service to nearly
2.1 million residential, commercial and industrial customers in Ohio,
Pennsylvania, Virginia, Kentucky and Maryland. These operations include 33,618
miles of pipelines, 1,350 acres (214 acres owned) covering 5,000 to 6,000
reservoir and protected acres of underground storage, 8 storage wells and one
compressor station with 800 horsepower of installed capacity. Columbia's
distribution subsidiaries are involved in programs that provide residential
customers the opportunity to purchase their natural gas requirements from third
parties and use the Columbia distribution subsidiaries for transportation
services.

Transmission and Storage Operations

Columbia's transmission and storage subsidiaries own and operate approximately
15,778 miles of interstate pipelines and operate one of the nation's largest
underground natural gas storage systems capable of storing approximately 670
billion cubic feet (Bcf) of natural gas. Through its subsidiaries, Columbia Gas
Transmission Corporation (Columbia Transmission) and Columbia Gulf Transmission
Company, 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, these companies serve customers in 15 northeastern, mid-Atlantic,
midwestern and southern states and the District of Columbia. The transmission
and storage subsidiaries are engaged in several projects that will expand their
service territory and throughput. The largest such project is Millennium
Pipeline, which will replace parts of an existing Columbia Transmission pipeline
and will transport 700 MDth of natural gas per day to growing markets in New
York and the northeast United States.

Exploration and Production Operations

Columbia Energy Resources, Inc. (Columbia Resources), is one of the largest
independent natural gas and oil producers in the Appalachian Basin. Columbia
Resources produced nearly 55.4 billion cubic feet equivalent (Bcfe) of natural
gas and oil for the 5 months ended December 31, 2002. For the year ended 2002,
Columbia Resources discovered 124.9 net Bcfe of gas and oil reserves and
participated in 243 gross (226.3 net) wells with a success rate of approximately
95 percent. At the end of 2002, Columbia Resources had financial interests in
over 8,300 wells, and had net proven gas and oil reserve holdings of 1.2
trillion cubic feet equivalent (Tcfe). Columbia Resources also owns and operates
approximately 6,200 miles of gathering pipelines. On January 28, 2003, Columbia
announced that its subsidiary Columbia Natural Resources, Inc. (CNR) sold its
interest in a natural gas exploration and production joint venture in New York
State, representing 39.3 Bcf in reserves and approximately 6.0 Bcf of
production, for approximately $95.0 million.

ITEM 1. BUSINESS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

Other

Other is comprised of the remaining gas sales obligations of Columbia Energy
Services Inc. (Columbia Energy Services), which was in the commercial and
residential natural gas retail business, and the operations of the remaining
microwave relay business.

For additional discussion of Columbia's business segments, including financial
information for the last three fiscal years, see the Notes to Consolidated
Financial Statements.

Competition and Changes in the Regulatory Environment

The regulatory frameworks applicable to Columbia's operations, at both the state
and federal levels, are undergoing fundamental changes. These changes have had
and will continue to have an impact on Columbia's operations, structure and
profitability. At the same time, competition within the gas industry 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 providing its gas customers with increased customer
choice for new products and services, disposing of non-core assets and
operations and developing new energy-related products and services for
residential, commercial and industrial customers.

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, local
distribution company (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 services
independent from the purchase of the commodity. Columbia's distribution
subsidiaries are involved in programs that provide residential customers the
opportunity to purchase their natural gas requirements from third parties and
use the Columbia distribution subsidiaries for transportation services.

Other Relevant Business Information

Columbia's customer base is broadly diversified, with no single customer
accounting for a significant portion of revenues.

As of December 31, 2002, Columbia had 4,384 employees of which 1,233 were
subject to collective bargaining agreements.

Columbia's subsidiaries are subject to extensive federal, state and local laws
and regulations relating to environmental matters. These laws and regulations,
which are constantly changing, require expenditures for corrective action at
various operating facilities, waste disposal sites and former gas manufacturing
sites for conditions resulting from past practices that have subsequently become
subject to environmental regulation. Information relating to environmental
matters is detailed in Note 15F of the Notes to Consolidated Financial
Statements.

ITEM 2. PROPERTIES

Information relating to properties is included in Item 1, Business and is
incorporated by reference herein. Assets under lien and other guarantees are
described in Note 15C and D of the Notes to Consolidated Financial Statements.

Neither Columbia nor any subsidiary knows of material defects in the title to
any real properties of the subsidiaries of Columbia or any material adverse
claim of any right, title, or interest therein, pending or contemplated.
Substantially all of Columbia Transmission's property has been pledged to
Columbia as security for First Mortgage Bonds issued by Columbia Transmission to
Columbia.

ITEM 3. LEGAL PROCEEDINGS

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

1. CANADA SOUTHERN PETROLEUM LTD. V. COLUMBIA GAS DEVELOPMENT OF CANADA LTD.
This action was originally filed March 7, 1990. The plaintiffs asserted,
among other things, that the defendant working interest owners, including
Columbia Gas Development of Canada Ltd. (Columbia Canada) and various
Amoco affiliates, breached an alleged fiduciary duty to ensure the
earliest feasible marketing of gas from the Kotaneelee field (Yukon
Territory, Canada). The plaintiffs sought, among other remedies, the
return of the defendants' interests in the Kotaneelee field to the
plaintiffs, a declaration that such interests are held in trust for the
plaintiffs and an order requiring the defendants to promptly market
Kotaneelee gas or assessing damages.

In November 1993, the plaintiffs amended their Amended Statement of Claim
to include allegations that the balance in the Carried Interest Account
(an account for operating costs, which are recoverable, by working
interest owners), which is in excess of the balance as of November 1988,
should be reduced to zero. Columbia Canada consented to the amendment in
consideration of the plaintiffs' acknowledgment that approximately $63
million was properly charged to the account.

Pursuant to an Indemnification Agreement regarding the Kotaneelee
Litigation entered into when Columbia Canada was sold to Anderson
Exploration Ltd. (Anderson), Columbia agreed to indemnify and hold
Anderson harmless for losses due to this litigation arising out of actions
occurring prior to December 31, 1991. An escrow account provides security
for the indemnification obligation and is funded by a letter of credit
with a face amount of approximately $35,835,000 (Cdn).

A trial commenced in the third quarter of 1996 in the Court of Queen's
Bench for the Province of Alberta and judgment was issued in September
2001. The court dismissed most of the plaintiffs' claims, including the
fiduciary duty claim, but did order a reduction of the Carried Interest
Account in the amount of $5.3 million (Cdn.) and ordered that the
defendants were not entitled to charge the plaintiffs processing fees. The
inability to charge the plaintiffs processing fees does not affect
Columbia. The monetary value of these two items has not been determined.
The plaintiffs have filed an appeal of the judgment. The Court set a
hearing date of December 1, 2, and 3, 2003, however, an earlier hearing
may be possible.

2. UNITED STATES OF AMERICA EX REL. JACK J. GRYNBERG V. COLUMBIA GAS
TRANSMISSION CORP., ET AL.

Plaintiff originally filed a complaint under the False Claims Act, on
behalf of the United States of America, against approximately seventy
pipelines. Plaintiff claimed that the defendants had submitted false
royalty reports to the government (or caused others to do so) by
mismeasuring the volume and heating content of natural gas produced on
Federal land and Indian lands. Plaintiff's original complaint was
dismissed without prejudice for misjoinder of parties and for failing to
plead fraud with specificity. In 1997, plaintiff then filed over
sixty-five new False Claims Act complaints against over 330 defendants in
numerous Federal courts. One of those complaints was filed in the Federal
District Court for the Eastern District of Louisiana against Columbia and
thirteen affiliated entities. Plaintiff's second complaint repeats the
mismeasurement claims previously made and adds valuation claims alleging
that the defendants have undervalued natural gas for royalty purposes in
various ways, including by making sales to affiliated entities at
artificially low prices. Most of the Grynberg cases were transferred to
Federal court in Wyoming in 1999. In December 1999, the Columbia
defendants filed a motion to dismiss plaintiff's second complaint
primarily based on a failure to plead fraud with specificity. In May 2001,
the Court denied the Columbia defendants' motion to dismiss. The Columbia
defendants joined together with numerous other defendants and filed a
motion requesting the district court to amend its order to include a
certification so that the defendants could request permission from the
United States Court of Appeals for the Tenth Circuit to appeal a
controlling question of law. That motion was denied on July 2, 2001.
Pretrial proceedings continue.

ITEM 3. LEGAL PROCEEDINGS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

3. PRICE ET AL V. GAS PIPELINES, ET AL.

Plaintiff filed an amended complaint in Stevens County, Kansas state court
on September 23, 1999, against over 200 natural gas measurers, mostly
natural gas pipelines, including Columbia and thirteen affiliated
entities. The allegations in Price (formerly known as Quinque) are similar
to those made in Grynberg; however, Price broadens the claims to cover all
oil and gas leases (other than the Federal and Indian leases that are the
subject of Grynberg). Price asserts a breach of contract claim, negligent
or intentional misrepresentation, civil conspiracy, common carrier
liability, conversion, violation of a variety of Kansas statutes and other
common law causes of action. Price purports to be a nationwide class
action filed on behalf of all similarly situated gas producers, royalty
owners, overriding royalty owners, working interest owners and certain
state taxing authorities. The defendants had previously removed the case
to Federal court. On January 12, 2001, the Federal court remanded the case
to state court. In June 2001, the plaintiff voluntarily dismissed ten of
the fourteen Columbia entities. Discovery relating to personal
jurisdiction has begun. On September 12, 2001 the four remaining Columbia
defendants along with other defendants filed a joint motion to dismiss the
amended complaint. That motion is currently pending before the court.

4. VIVIAN K. KERSHAW ET AL. V. COLUMBIA NATURAL RESOURCES, INC., ET AL.

In February 2000, plaintiff filed a complaint in New York state court
against Columbia, Columbia Natural Resources, Inc. (CNR) and Columbia
Transmission. The complaint alleges that Kershaw owns an interest in an
oil and gas lease in New York and that the defendants have underpaid
royalties on the lease by, among other things, failing to base royalties
on the price at which natural gas is sold to the end user and by
improperly deducting post-production costs. The complaint also seeks class
action status on behalf of all royalty owners in oil and gas leases
operated by CNR. Plaintiff seeks the alleged royalty underpayments and
punitive damages. CNR and Columbia Transmission removed the case to
Federal court in March 2000. The Federal court has remanded Kershaw back
to New York state court. The Columbia defendants' motion to dismiss was
partially granted and partially denied by the New York state court judge
on September 24, 2001. On December 3, 2001, the defendants filed an answer
to the plaintiffs' complaint. Discovery regarding class certification is
ongoing.

5. ANTHONY GONZALEZ, ET AL. V. NATIONAL PROPANE CORPORATION, ET AL.

On December 11, 1997, plaintiffs Anthony Gonzalez, Helen Pieczynski, as
Special Administrator of the Estate of Edmund Pieczynski, deceased,
Michael Brown and Stephen Pieczynski filed a multiple-count complaint for
personal injuries in the Circuit Court of Cook County, Illinois against
National Propane Corporation and the Estate of Edmund Pieczynski sounding
in strict tort liability and negligence. National Propane Corporation was
acquired by Columbia in 1999, and this litigation was retained by Columbia
when Columbia sold its propane operations in 2001. Plaintiff's complaint
arises from an explosion and fire, which occurred in a Wisconsin vacation
cottage in 1997. National Propane, L.P. filed a third-party complaint for
contribution against Natural Gas Odorizing and Phillips Petroleum Company.
Columbia is pursuing a settlement in respect to this matter.

Consolidated Review...................................................... 7
Liquidity and Capital Resources.......................................... 9


The information required by this Item is presented in a reduced disclosure
format pursuant to General Instruction I to Form 10-K. The Notes to Consolidated
Financial Statements contain information that is pertinent to the following
analysis.

The Management's Narrative and Analysis of Results of Operations, including
statements regarding market risk sensitive instruments, contains
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. Investors and prospective investors should understand that many
factors govern whether any forward-looking statement contained herein will be or
can be realized. Any one of those factors could cause actual results to differ
materially from those projected. These forward-looking statements include, but
are not limited to, statements concerning Columbia's plans, dispositions,
objectives, expected performance, expenditures and recovery of expenditures
through rates, stated on a consolidated basis, any and all underlying
assumptions and other statements that are other than historical fact. From time
to time, Columbia may publish or otherwise make available forward-looking
statements of this nature. All such subsequent forward-looking statements,
whether written or oral and whether made by or on behalf of Columbia, are also
expressly qualified by these cautionary statements. All forward-looking
statements are based on assumptions that management believes to be reasonable;
however, there can be no assurance that actual results will not differ
materially. Realization of Columbia's objective and expected performance is
subject to a wide range of risks and can be adversely affected by, among other
things, increased competition in deregulated energy markets, weather conditions,
fluctuations in supply and demand for energy commodities, service territories,
successful consummation of dispositions, growth opportunities for Columbia's
regulated and non-regulated businesses, dealings with third parties over whom
Columbia has no control, the regulatory process, regulatory and legislative
changes, changes in general economic, capital and commodity market conditions
and counter-party credit risk, many of which are beyond the control of Columbia.

CONSOLIDATED REVIEW

Columbia's income from continuing operations for 2002 was $473.1 million, an
increase of $170.3 million from 2001. Income from continuing operations for 2001
was $302.8 million, an increase of $17.9 million from 2000.

Taking into account income from continuing operations and the loss from
discontinued operations, Columbia reported net income of $415.4 million in 2002,
an increase of $225.5 million from the prior year. Columbia reported net income
of $189.9 million in 2001, an increase of $78.1 million from the prior year.

Net Revenues

Total net revenues of $1,943.5 million for 2002 reflected a decrease of
approximately $55.6 million from 2001. The decrease in revenues was primarily
attributable to lower prices related to increased sales of natural gas
production to satisfy requirements under forward sales agreements amounting to
$32.7 million, reduced off systems sales, incentive programs and
non-weather-related gas sales totaling $23.8 million, and an $8.5 million
reduction in gains on the sales of storage base gas. Slightly offsetting the
decrease was a $12.9 million impact of favorable weather due to a much colder
heating season during the latter part of 2002, which increased natural gas sales
and deliveries.

For 2001, total net revenues of $1,999.1 million increased $43.6 million over
2000 primarily due an increase in gas production with increases in both volumes
and prices totaling $61.7 million. Partially offsetting the increase was the
impact of unfavorable weather of $23.7 million.

Expenses

Total operating expenses for 2002 were $1,124.9 million, a decrease of $226.6
million from 2001, attributable to the reversal of $49.7 million of reserves
related to estimated taxes, environmental site characterization results for the
pipeline operations and litigation issues; $37.0 due to reduced dry well,
geological and other gas and oil production expenses; reduced employee-related,
support service and facility expenses amounting to $35.0 million; and $23.6
million from insurance recoveries of environmental expenditures. The 2001 period
was negatively affected by $76.5 million from the recognition of reserves mainly
comprised of estimated environmental costs for manufactured gas plant sites,
legal issues and estimated unrecoverable operating gas costs.


7


ITEM 7. MANAGEMENT'S NARRATIVE AND ANALYSIS OF RESULTS OF OPERATIONS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

Total operating expenses for 2001 were $1,351.5 million, an increase of $16.2
million from 2000. The increase was primarily due to the earlier period having
been favorably impacted by pre-tax gains of $130.6 million and $90.5 million
on the sales of Columbia Electric and Cove Point LNG, respectively.
Also contributing to the increase were environmental and litigation
contingencies amounting to $56.0 million which were recorded in the 2001 period
and increased depreciation and depletion expenses of $10.8 million, due in part
to the write down of certain impaired assets in Columbia Resources' Canadian
producing region. Mostly offsetting the increase was lower operation and
maintenance costs associated with merger-related expenses recorded in 2000
amounting to $228.4 million, lower payroll and benefits costs totaling $15.5
million, which resulted from the 2000 Voluntary Incentive Retirement Program,
and lower property taxes totaling $33.7 million.

Other Income (Deductions)

Interest expense and related charges of $115.1 million decreased $55.3 million
primarily due to lower short-term interest rates. Interest expense and related
charges remained relatively consistent between 2001 and 2000.

Income Taxes

Income tax expense in 2002 totaled $254.5 million, an increase of $66.1 million
from 2001, primarily as a result of higher pre-tax income in 2002 as compared to
the earlier period. The increase was partly offset by a slightly lower effective
tax rate partly due to a lower estimate of average state income taxes for 2002
and $16.1 million in adjustments related to prior years' tax liabilities.

Income tax expense of $188.4 million for 2001 increased $7.7 million from 2000,
primarily due to higher pre-tax income.

Discontinued Operations

Discontinued operations reflected an after-tax loss of $57.7 million in 2002
compared to an after-tax loss of $116.9 million in 2001. The 2002 period was
unfavorably impacted by a non-cash charge of $51.3 million, after-tax, as a
result of the continuing depressed market for dark fiber and Columbia's decision
to exit the telecommunications business. The 2001 loss was comprised of an
initial write-down of the telecommunication assets amounting to $58.0 million,
after-tax, and an after-tax loss on the sale of Columbia Propane Corporation of
$50.6 million.

Discontinued operations reflected an after-tax loss of $116.9 million in 2001
compared to an after-tax loss of $173.1 million in 2000. During 2000, Columbia
undertook an evaluation of the appropriateness of remaining in certain
businesses given the rapidly changing energy industry and the pending merger
with NiSource. As a result of this assessment, Columbia decided to exit the
energy marketing operations, which included the propane, petroleum and Columbia
Energy Services' mass marketing business.

Accounting Change

Effective January 1, 2001, Columbia adopted the Financial Accounting Standards
Board's (FASB) Statement of Financial Accounting Standards (SFAS) No. 133,
"Accounting for Derivative Instruments and Hedging Activities", as subsequently
amended by SFAS No. 137 and SFAS No. 138 (collectively referred to as SFAS No.
133). These statements establish accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives) and for hedging
activities. SFAS No. 133 requires an entity to recognize all derivatives as
either assets or liabilities on the balance sheet and measure those instruments
at fair value. If certain conditions are met, a derivative may be specifically
designated as (a) a hedge of the exposure to changes in the fair value of a
recognized asset or liability or an unrecognized firm commitment or (b) a hedge
of the exposure to variable cash flows of a forecasted transaction. The
accounting for changes in the fair value of a derivative depends on the intended
use of the derivative and resulting designation.

The adoption of this statement on January 1, 2001, resulted in a cumulative
after-tax increase to net income of approximately $4.0 million and an after-tax
reduction to accumulated other comprehensive income (OCI) of approximately $33.6
million, which was recognized in earnings during 2002 and 2001. The adoption
also resulted in the recognition of $160.2 million of assets and $193.8 million
of liabilities on the consolidated balance sheet. Additionally, the adoption
resulted in the reduction of the carrying value of certain long-term debt by
$3.8 million.

Refer to "Summary of Significant Accounting Policies - Accounting for Risk
Management Activities" and "Risk Management Activities" in the Notes to the
Consolidated Financial Statements for further discussion of Columbia's risk
management.

ITEM 7. MANAGEMENT'S NARRATIVE AND ANALYSIS OF RESULTS OF OPERATIONS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

LIQUIDITY AND CAPITAL RESOURCES

A significant portion of Columbia's operations is subject to seasonal
fluctuations in cash flows. During the heating season, which is primarily from
November through March, cash receipts from sales and transportation services
typically exceed cash requirements. Conversely, during the remainder of the
year, cash on hand together with external short-term financing, as needed, is
used to purchase gas to place in storage for heating season deliveries, perform
necessary maintenance on facilities, make capital improvements in plant and
expand service.

Net cash from continuing operations for the year ended December 31, 2002 was
$877.9 million, a $124.0 million increase from the same period in 2001,
principally driven by increased earnings, partly offset by increased payments
for current liabilities and the timing of the recovery of gas costs.

Columbia satisfies its liquidity requirements primarily through internally
generated funds and through intercompany borrowings from the NiSource Money
Pool. Columbia may borrow on an intercompany basis a maximum of $1.0 billion
through the NiSource Money Pool as approved by the Securities and Exchange
Commission (SEC) under the 1935 Act. NiSource Finance Corp. (NFC) provides
funding to the NiSource Money Pool from external borrowing sources and maintains
an aggregate $1.75 billion revolving credit facility with a syndicate of banks
which will be reduced to $1.25 billion upon the expiration of a $500.0 million
364-day credit facility on March 20, 2003. The credit facility is guaranteed by
NiSource. As of December 31, 2002, Columbia had $136.4 million of intercompany
short-term borrowings with NFC outstanding at a weighted average interest rate
of 2.11%.

Columbia has entered into interest rate swap agreements to modify the interest
characteristics of its outstanding long-term debt. Under the terms of the swap
agreements, Columbia pays interest based on a floating rate index and receives
interest based on a fixed rate. The effect of these agreements is to modify the
interest rate characteristics of a portion of Columbia's long-term debt from
fixed to variable and to hedge the fair value of the underlying debt. On
September 3, 2002, Columbia entered into new fixed-to-variable interest rate
swap agreements totaling $281.5 million with three counterparties effective as
of September 5, 2002. According to the agreements, Columbia will receive
payments based upon a fixed 7.32% interest rate and will pay a floating interest
amount based on U.S. 6-month LIBOR-BBA plus 2.66% per annum. In total, Columbia
has entered into fixed-to-variable interest rate swaps on $663.0 million of its
long-term debt.

On November 28, 2002, $281.5 million of Columbia's outstanding 6.61% Series B
Debentures was redeemed using cash from operations.

Columbia Gas of Ohio, Inc. (Columbia of Ohio) is a party to an agreement to
sell, without recourse, a majority of its trade receivables to Columbia Accounts
Receivable Corporation (CARC), a wholly-owned subsidiary of Columbia. CARC, in
turn, is party to an agreement in which it sells a percentage ownership interest
in a defined pool of the accounts receivable to a commercial paper conduit.
Under these agreements, CARC may not sell any new affiliate receivables to the
conduit if Columbia's debt rating falls below BBB- or Baa3 at Standard and
Poor's and Moody's, respectively. In addition, if Columbia's debt rating falls
below BB or Ba2, the agreements terminate and CARC may not sell any new
receivables to the conduit. As of December 31, 2002, Columbia of Ohio had sold
$99.5 million to the conduit.

Contractual Obligations and Commercial Commitments

Columbia has certain contractual obligations that extend beyond 2003. The
obligations include long-term debt, lease obligations, and purchase obligations
for pipeline capacity, transportation and storage services through Columbia's
Distribution subsidiaries. The total contractual obligations in existence at
December 31, 2002 were:

ITEM 7. MANAGEMENT'S NARRATIVE AND ANALYSIS OF RESULTS OF OPERATIONS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

Columbia has made certain commercial commitments that extend beyond 2003. The
commitments support commercial activities. The total commercial commitments in
existence at December 31, 2002 and the years in which they expire were:

-------- -------- -------- -------- -------- --------
Total commercial commitments $ 144.0 $ -- $ 112.2 $ 977.8 $ 47.9 $ 290.6
-------- -------- -------- -------- -------- --------


Pension Funding

Due to lower than expected returns on plan assets over the past three years and
a lower assumed discount rate, Columbia's pension plans are currently in an
underfunded position. Although Columbia expects market returns to revert to
normal levels as demonstrated in historical periods, Columbia may be required to
provide additional funding for the obligations if returns on plan assets fall
short of the assumed 9.0% long-term rate. Also, Columbia expects pension expense
for 2003 to increase approximately $12.0 million over the amount recognized in
2002. See Note 10 of Notes to the Consolidated Financial Statements for more
information.

Management believes that its sources of funding are sufficient to meet the
short-term and long-term liquidity needs of Columbia.

OTHER INFORMATION

Critical Accounting Policies

Columbia applies certain accounting policies based on the accounting
requirements discussed below that have had, and may continue to have,
significant impacts on Columbia's results of operations and consolidated balance
sheets.

SFAS NO. 71 - ACCOUNTING FOR THE EFFECTS OF CERTAIN TYPES OF REGULATION. SFAS
No. 71, "Accounting for the Effects of Certain Types of Regulation" (SFAS No.
71), provides that rate-regulated subsidiaries account for and report assets and
liabilities consistent with the economic effect of the way in which regulators
establish rates, if the rates established are designed to recover the costs of
providing the regulated service and if the competitive environment makes it
probable that such rates can be charged and collected. Columbia's rate-regulated
subsidiaries follow the accounting and reporting requirements of SFAS No. 71.
Certain expenses and credits subject to utility regulation or rate determination
normally reflected in income are deferred on the balance sheet and are
recognized in income as the related amounts are included in service rates and
recovered from or refunded to customers. The total amounts of regulatory assets
and liabilities reflected on the Consolidated Balance Sheets were $525.6 million
and $56.4 million at December 31, 2002, and $499.7 million and $93.3 million at
December 31, 2001, respectively.

In the event that regulation significantly changes the opportunity for Columbia
to recover its costs in the future, all or a portion of Columbia's regulated
operations may no longer meet the criteria for the application of SFAS No. 71.
In such event, a write-down of all or a portion of Columbia's existing
regulatory assets and liabilities could result. If transition cost recovery is
approved by the appropriate regulatory bodies that would meet the requirements
under generally accepted accounting principles for continued accounting as
regulatory assets and liabilities during such recovery period, the regulatory
assets and liabilities would be reported at the recoverable amounts. If unable
to continue to apply the provisions of SFAS No. 71, Columbia would have to apply
the provisions of SFAS No. 101, "Regulated Enterprises - Accounting for the
Discontinuation of Application of FASB Statement No. 71." In management's
opinion, Columbia's regulated subsidiaries will be subject to SFAS No. 71 for
the foreseeable future.

Certain of the regulatory assets reflected on Columbia's Consolidated Balance
Sheets require specific regulatory action in order to be included in future
service rates. Although recovery of these amounts is not guaranteed, Columbia
believes that these costs meet the requirements for deferral as regulatory
assets under SFAS No. 71. Regulatory assets requiring specific regulatory action
amounted to $117.5 million at December 31, 2002. If Columbia determined that the
amounts included as regulatory assets were not recoverable, a charge to income
would immediately be required to the extent of the unrecoverable amounts.

ITEM 7. MANAGEMENT'S NARRATIVE AND ANALYSIS OF RESULTS OF OPERATIONS (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES

HEDGING ACTIVITIES. Under SFAS No. 133, the accounting for changes in the fair
value of a derivative depends on the intended use of the derivative and
resulting designation. Unrealized and realized gains and losses are recognized
each period as components of other comprehensive income, regulatory assets and
liabilities or earnings depending on the nature of such derivatives. For
subsidiaries that utilize derivatives for cash flow hedges, the effective
portions of the gains and losses are recorded to other comprehensive income and
are recognized in earnings concurrent with the disposition of the hedged risks.
For fair value hedges, the gains and losses are recorded in earnings each period
along with the change in the fair value of the hedged item. As a result of the
rate-making process, the rate-regulated subsidiaries generally record gains and
losses as regulatory liabilities or assets and recognize such gains or losses in
earnings when recovered in revenues.

In order for a derivative contract to be designated as a hedge, the relationship
between the hedging instrument and the hedged item or transaction must be highly
effective. The effectiveness test is performed at the inception of the hedge and
each reporting period thereafter, throughout the period that the hedge is
designated. Any amounts determined to be ineffective are recorded currently in
earnings.

Although Columbia applies some judgment in the assessment of hedge effectiveness
to designate certain derivatives as hedges, the nature of the contracts used to
hedge the underlying risks is such that the correlation of the changes in fair
values of the derivatives and underlying risks is generally high. Columbia
generally uses NYMEX exchange-traded natural gas futures and options contracts
and over-the-counter swaps based on published indices to hedge the risks
underlying its natural gas-related businesses. Columbia had $138.4 million of
price risk management assets and $8.5 million of price risk management
liabilities primarily related to cash flow hedges at December 31, 2002. The
amount of unrealized gains recognized in other comprehensive income was $65.0
million at December 31, 2002.

PENSIONS AND POSTRETIREMENT BENEFITS. Columbia has defined benefit plans for
both pensions and other postretirement benefits. The plans are accounted for
under SFAS No. 87, "Employers' Accounting for Pensions," and SFAS No. 106,
"Employers' Accounting for Postretirement Benefits Other than Pensions." The
calculation of the net obligations and annual expense related to the plans
requires a significant degree of judgment regarding the discount rates to be
used in bringing the liabilities to present value, long-term returns on plan
assets and employee longevity, amongst other assumptions. Due to the size of the
plans and the long-term nature of the associated liabilities, changes in the
assumptions used in the actuarial estimates could have material impacts on the
measurement of the net obligations and annual expense recognition. For further
discussion of Columbia's pensions and other postretirement benefits see Note 10
of the Notes to Consolidated Financial Statements.

INDEPENDENT AUDITORS' REPORT

To the Shareholder of Columbia Energy Group:

We have audited the accompanying consolidated balance sheets of Columbia Energy
Group (a Delaware corporation, the "Corporation" and a wholly owned subsidiary
of NiSource Inc.) and subsidiaries as of December 31, 2002 and 2001, and the
related statements of consolidated income, cash flows and common stock equity
for each of the three years in the period ended December 31, 2002. Our audits
also included the financial statement schedules listed in the index at Item 8.
These financial statements and financial statement schedules are the
responsibility of the Corporation's management. Our responsibility is to express
an opinion on the financial statements and financial statement schedules based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Corporation and subsidiaries as of
December 31, 2002, and 2001, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 2002 in
conformity with accounting principles generally accepted in the United States of
America. Also, in our opinion, such financial statement schedules, when
considered in relation to the basic consolidated financial statements taken as a
whole, present fairly in all material respects the information set forth
therein.

As explained in Note 1L to the financial statements, effective January 1, 2001,
the Corporation adopted Statement of Financial Accounting Standards No. 133,
"Accounting for Derivatives Instruments and Hedging Activities," as amended.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include
the accounts of Columbia Energy Group (Columbia) and its wholly-owned
subsidiaries after the elimination of all intercompany accounts and
transactions. Investments for which at least a 20% interest is owned, certain
joint ventures and limited partnership interests of more than 3% are accounted
for under the equity method. Except where noted above, investments with less
than a 20% interest are accounted for under the cost method. Net earnings from
investments are reflected as a component of gross revenues. Certain
reclassifications have been made to the prior period financial statements to
conform to the 2002 presentation.

B. CASH AND CASH EQUIVALENTS. Columbia considers all investments with original
maturities of three months or less to be cash equivalents. Columbia reports
amounts required to be deposited in brokerage accounts for margin requirements
in the restricted cash balance sheet caption.

C. BASIS OF ACCOUNTING FOR RATE-REGULATED SUBSIDIARIES. Statement of Financial
Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types
of Regulation" (SFAS No. 71), provides that rate-regulated subsidiaries account
for and report assets and liabilities consistent with the economic effect of the
way in which regulators establish rates, if the rates established are designed
to recover the costs of providing the regulated service and if the competitive
environment makes it probable that such rates can be charged and collected.
Columbia's rate-regulated subsidiaries follow the accounting and reporting
requirements of SFAS No. 71. Certain expenses and credits subject to utility
regulation or rate determination normally reflected in income are deferred on
the balance sheet and are recognized in income as the related amounts are
included in service rates and recovered from or refunded to customers. In the
event that regulation significantly changes the opportunity for Columbia to
recover its costs in the future, all or a portion of Columbia's regulated
operations may no longer meet the criteria for the application of SFAS No. 71.
In such event, a write-down of all or a portion of Columbia's existing
regulatory assets and liabilities could result. If transition cost recovery is
approved by the appropriate regulatory bodies that would meet the requirements
under generally accepted accounting principles for continued accounting as
regulatory assets and liabilities during such recovery period, the regulatory
assets and liabilities would be reported at the recoverable amounts. If Columbia
would not be able to continue to apply the provisions of SFAS No. 71, Columbia
would be required to apply the provisions of SFAS No. 101, "Regulated
Enterprises - Accounting for the Discontinuation of Application of Financial
Accounting Standards Board (FASB) Statement No. 71." In management's opinion,
Columbia's regulated subsidiaries will be subject to SFAS No. 71 for the
foreseeable future.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Regulatory assets of approximately $220.8 million are not presently included in
the rate base and consequently are not earning a return on investment. These
regulatory assets are being recovered through cost of service. The remaining
recovery periods generally range from one to fifteen years. Regulatory assets of
approximately $117.5 million require specific rate action.

The Public Utility Commission of Ohio (PUCO) authorized Columbia of Ohio, Inc.
(Columbia of Ohio) to revise its depreciation accrual rates for the period
January 1, 1999 through December 31, 2004. The revised depreciation rates are
lower than those, which would have been utilized if Columbia of Ohio were not
subject to regulation. The amount of depreciation that would have been recorded
for 2002 had Columbia of Ohio not been subject to rate regulation was $34.2
million, a $20.8 million increase over the $13.4 million reflected in rates.
Including amounts for years prior to 2002, a regulatory asset has been
established in the amount of $85.3 million at December 31, 2002.

D. UTILITY PLANT AND OTHER PROPERTY AND RELATED DEPRECIATION. Property, plant
and equipment (principally utility plant) are stated at cost. For rate-regulated
companies, an allowance for funds used during construction (AFUDC) is
capitalized on all classes of property except organization, land, autos, office
equipment, tools and other general property purchases. The allowance is applied
to construction costs for that period of time between the date of the
expenditure and the date on which such project is completed and placed in
service. For non-regulated companies, interest during construction (IDC) is
capitalized pursuant to SFAS No. 34, "Capitalization of Interest Cost." The 2002
pre-tax rates for AFUDC and IDC were 3.3% and 7.5%, respectively. The 2001 and
2000 pre-tax rates for AFUDC were 7.6% and 6.8%, respectively, and for IDC were
6.8% and 6.8%, respectively. The decline in the 2002 AFUDC rate, as compared
with 2001, was due to lower short-term interest rates and the use of short-term
borrowings to fund construction efforts.

Improvements and replacements of retirement units are capitalized at cost. When
units of property are retired, the accumulated provision for depreciation is
charged with the cost of the units and the cost of removal, net of salvage.
Maintenance, repairs and minor replacements of property are charged to expense.

Columbia's subsidiaries provide for annual depreciation on a composite
straight-line basis. The average annual depreciation rates for the distribution
subsidiaries' property were 2.7%, 2.8% and 2.8% in 2002, 2001, and 2000. The
average annual depreciation rates for the transmission subsidiaries' property
were 2.3%, 2.4% and 2.4% in 2002, 2001, and 2000.

E. INTANGIBLE ASSETS. Intangible assets are recorded at cost (i.e. estimated
fair value) and are amortized on a straight-line basis. Of the $3.0 million of
intangible assets, Columbia had approximately $2.3 million of intangible assets
recorded at December 31, 2002, which reflected the additional minimum liability
associated with the unrecognized prior service cost of the pension plans
pursuant to SFAS No. 87, "Employers' Accounting for Pensions."

F. REVENUE RECOGNITION. Columbia's distribution subsidiaries bill customers on a
monthly cycle billing basis. Revenues are recorded on the accrual basis and
include an estimate for gas delivered but unbilled at the end of each accounting
period. Cash received in advance from sales of commodities to be delivered in
the future is deferred and recognized as income upon delivery of the commodity.

G. ESTIMATED RATE REFUNDS. Certain rate-regulated subsidiaries collect revenues
subject to refund pending final determination in rate proceedings. In connection
with such revenues, estimated rate refunds liabilities are recorded which
reflect management's current judgment of the ultimate outcome of the
proceedings. No provisions are made when, in the opinion of management, the
facts and circumstances preclude a reasonable estimate of the outcome.

H. ACCOUNTS RECEIVABLE SALES PROGRAM. Columbia enters into agreements with third
parties to sell certain accounts receivable without recourse. These sales are
reflected as reductions of accounts receivable in the accompanying consolidated
balance sheets and as operating cash flows in the accompanying consolidated
statements of cash flows. The costs of this program, which are based upon the
purchasers' level of investment and borrowing costs, are charged to other income
in the accompanying consolidated statements of income.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

I. USE OF ESTIMATES. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates

J. GAS COST ADJUSTMENT CLAUSE. Columbia's distribution subsidiaries defer
differences between gas purchase costs and the recovery of such costs in
revenues, and adjust future billings for such deferrals on a basis consistent
with applicable tariff provisions.

K. GAS INVENTORY. The distribution subsidiaries' gas inventory is carried at
cost on a last-in, first-out (LIFO) basis. The excess of replacement cost of gas
inventory at December 31, 2002, over the carrying value is approximately $194.8
million. Liquidation of LIFO layers related to gas delivered by the distribution
subsidiaries does not affect income since the effect is passed through to
customers as part of purchased gas adjustment tariffs.

L. ACCOUNTING FOR RISK MANAGEMENT ACTIVITIES. SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activity" (SFAS No. 133), establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS No. 133 requires an entity to
recognize all derivatives as either assets or liabilities on the balance sheet
at fair value. The accounting for changes in the fair value of a derivative
depends on the intended use of the derivative and resulting designation.
Columbia adopted SFAS No. 133 effective January 1, 2001, resulting in a
cumulative after-tax increase to net income of approximately $4.0 million and an
after-tax reduction to other comprehensive income of approximately $33.6
million.

If certain conditions are met, a derivative may be specifically designated as
(a) a hedge of the exposure to changes in the fair value of a recognized asset
or liability or an unrecognized firm commitment, or (b) a hedge of the exposure
to variable cash flows of a forecasted transaction. In order for a derivative
contract to be designated as a hedge, the relationship between the hedging
instrument and the hedged item or transaction must be highly effective. The
effectiveness test is performed at the inception of the hedge and each reporting
period thereafter, throughout the period that the hedge is designated. Any
amounts determined to be ineffective are recognized currently in earnings.

Unrealized and realized gains and losses are recognized each period as
components of other comprehensive income, regulatory assets and liabilities or
earnings depending on the nature of such derivatives. For subsidiaries that
utilize derivatives for cash flow hedges, the effective portions of the gains
and losses are recorded to other comprehensive income and are recognized in
earnings concurrent with the completion of the hedged transaction. If a
forecasted transaction corresponding to a cash flow hedge is not expected to
occur, the accumulated gains or losses on the derivative are recognized
currently in earnings. For fair value hedges, the gains and losses are recorded
in earnings each period along with the change in the fair value of the hedged
item. As a result of the rate-making process, the rate-regulated subsidiaries
generally record gains and losses as regulatory liabilities or assets and
recognize such gains or losses in earnings consistent with the rate treatment.

M. INCOME TAXES AND INVESTMENT TAX CREDITS. Columbia and its subsidiaries record
income taxes to recognize full interperiod tax allocations. Under the liability
method of income tax accounting, deferred income taxes are recognized for the
tax consequences of temporary differences by applying enacted statutory tax
rates applicable to future years to differences between the financial statement
carrying amounts and the tax basis of existing assets and liabilities.
Previously recorded investment tax credits of the regulated subsidiaries were
deferred and are being amortized over the life of the related properties to
conform to regulatory treatment.

Columbia joins in the filing of consolidated federal and state income tax
returns with its parent company, NiSource Inc. (NiSource), and certain of
NiSource's other affiliated companies. Columbia and its subsidiaries are parties
to a tax allocation agreement under which the consolidated tax is allocated
among the members of the group in proportion to each member's relative
contribution to the group's consolidated tax liability. Additionally, NiSource's
tax savings are allocated to its subsidiaries and recognized as adjustments to
equity. The amount of tax savings allocated to Columbia for the 2001 tax year
was $12.7 million.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

N. ENVIRONMENTAL EXPENDITURES. Columbia accrues for costs associated with
environmental remediation obligations when the incurrence of such costs is
probable and the amounts can be reasonably estimated, regardless of when the
expenditures are actually made. The undiscounted estimated future expenditures
are based on currently enacted laws and regulations, existing technology and
site-specific costs. The liability is adjusted as further information is
discovered or circumstances change. Rate-regulated subsidiaries applying SFAS
No. 71 establish regulatory assets on the balance sheet to the extent that
future recovery of environmental remediation costs is probable through the
regulatory process.

O. AFFILIATED COMPANY TRANSACTIONS. Columbia receives executive, financial,
sales and marketing, and administrative and general services from an affiliate,
NiSource Corporate Services Company (NCS), a wholly-owned subsidiary of
NiSource. The costs of these services are charged to Columbia based on payroll
costs consists primarily of employee compensation and benefits and expenses
incurred by NCS employees for the benefit of Columbia. These costs totaled
$193.2 million, $199.2 million and $188.6 million for 2002, 2001 and 2000,
respectively, consisting primarily of employee compensation and benefits that
were included in operation and maintenance expense.

Columbia recorded gas sales, transportation and storage revenues from affiliates
of $48.5 million, $75.2 million and $1.2 million and purchased natural gas from
affiliated companies in the amount of $3.4 million, $19.5 million and $10.2
million during 2002, 2001 and 2000, respectively.

At December 31, 2002, Columbia had $136.4 million of affiliated short-term
borrowings from the NiSource Money Pool at a weighted average interest rate of
2.1%, which was included in the line caption "Accounts Payable" on the balance
sheet.

Columbia had notes receivable from NCS totaling $23.9 million, all of which were
non-current at December 31, 2002. The interest is payable semi-annually and is
based on rates ranging from 7.3% to 8.1 %. The maturities range from November
2005 to November 2025.

P. EXCISE TAXES. Columbia accounts for excise taxes that are customer
liabilities by separately stating on its invoices the tax to its customers and
recording amounts invoiced as liabilities payable to the applicable taxing
jurisdiction. These types of taxes, comprised largely of sales taxes collected,
are presented on a net basis affecting neither revenues nor cost of sales.
Columbia accounts for other taxes for which it is liable by recording a
liability for the expected tax with a corresponding charge to "Other Taxes"
expense.

Q. GAS AND OIL PRODUCING PROPERTIES. Columbia accounts for the acquisition,
exploration and development activities related to oil and gas reserves using the
successful efforts method. Under the successful efforts method of accounting,
except for property acquisition costs, only costs associated with specific
discovered reserves are capitalized. Capitalized costs include mineral interests
in properties, wells and related equipment and facilities, support equipment,
and uncompleted wells. Depletion expense is equal to annual production
multiplied by the depletion rate per unit that is derived by spreading the total
costs capitalized under successful efforts over the number of units expected to
be extracted over the life of the reserves on a lease basis.

2. REGULATORY MATTERS

Changes in gas industry regulation, which began in the mid-1980s at the federal
level, have broadened to retail customers at the state level. Large industrial
and commercial customers have had the ability to purchase natural gas directly
from marketers and to use Distribution's facilities for transportation services
for many years. This opportunity to choose an alternative supplier has been
migrating into the small commercial and residential customer classes with
approved or pilot transportation programs being used in all states served by
Columbia's five distribution subsidiaries. As of December 31, 2002,
approximately 0.7 million of Distribution's residential and commercial customers
had selected an alternate supplier.

Distribution continues to explore customer choice opportunities through
regulatory initiatives in all of its jurisdictions. While these programs are
intended to provide all customer classes with the opportunity to obtain gas
supplies from alternative merchants, Distribution expects to play a
substantial role in supplying gas commodity services to its customers in the
foreseeable future. As customers enroll in these programs and purchase their gas
from other suppliers, the Distribution subsidiaries are sometimes left with
pipeline capacity they have contracted for, but no longer need. The state
commissions in jurisdictions served by Distribution are at various stages in
addressing these issues and other transition considerations. Distribution is
currently recovering, or has


22

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

the opportunity to recover, the costs resulting from the unbundling of its
services and believes that most of such future costs will be mitigated or
recovered. Methodologies for mitigating or recovering transition costs include
incentive sharing mechanisms, reducing levels of pipeline capacity and mandatory
assignment of pipeline capacity to alternative suppliers.

In December 1999, the PUCO approved a request from Columbia of Ohio that
extends Columbia of Ohio's Customer CHOICE(SM) program through October 31, 2004,
freezing base rates through October 31, 2004 and resolves the issue of
transition costs from pipeline capacity. Under the agreement, Columbia of Ohio
assumes total financial risk for mitigation of transition capacity costs at no
additional cost to customers. Columbia of Ohio has the opportunity to utilize
non-traditional revenue sources as a means of offsetting the costs.

On November 20, 2001, the PUCO issued final rules to implement the provisions of
choice legislation enacted by the Ohio General Assembly on March 27, 2001. The
rules have been approved by a Joint Committee on Agency Rule Review of the Ohio
Legislature, and were effective on July 5, 2002. The new rules establish the
process for PUCO certification and regulation of competitive retail natural gas
suppliers, establish minimum service standards for competitive natural gas
suppliers, and specify the procedures for establishment of governmental
aggregation programs, in which consumers have the right to "opt-out" of the
program. Columbia of Ohio filed tariffs incorporating the rules on November 1,
2002. A number of communities in the service territory of Columbia of Ohio have
passed aggregation initiatives in recent elections. There are approximately 0.2
million eligible customers in these communities. Two communities began
governmental aggregation in late 2002 and it is anticipated that other
communities will begin the governmental aggregations in 2003.

As part of the Kentucky Public Service Commission (KPSC) order approving the
acquisition of Columbia, Columbia Gas of Kentucky, Inc. (Columbia of Kentucky)
was required to file a rate case that included an estimate of net merger savings
and a mechanism to reflect merger savings on customers' bills. On May 1, 2002,
Columbia of Kentucky filed a general rate case, requesting an increase in
revenue of approximately $2.5 million or 4% of annual operating revenues
including the net merger savings. On September 30, 2002, Columbia of Kentucky
and all other parties of record in this proceeding filed a settlement with the
KPSC. The settlement was approved by the KPSC on December 13, 2002. The
settlement reduces Columbia of Kentucky's base rates by $7.8 million, with $0.5
million of the reduction recovered through a tracking mechanism to cover the
costs of a program to support low-income customers. The changes become effective
in March 2003.

3. NISOURCE ACQUISITION OF COLUMBIA

On November 1, 2000, NiSource Inc. (NiSource) completed its acquisition of
Columbia for an aggregate consideration of approximately $6 billion, primarily
consisting of $3.9 billion in cash, 72.4 million shares of common stock valued
at $1.8 billion and Stock Appreciation Income Linked Securities(SM), referred to
as SAILSSM, (units each consisting of zero coupon debt security coupled with a
forward equity contract) valued at $114 million. NiSource also assumed
approximately $2 billion in Columbia debt. As part of the Merger Agreement, the
stock options under Columbia's Long-Term Incentive Plans were cancelled. The
holders of the stock options received approximately $120.6 million from the
cash-out of the stock options. The acquisition of Columbia by NiSource triggered
change in control payments of approximately $44.5 million under certain
employment agreements. The cost of the cash-out of the stock options and the
change of control payments of approximately $155.9 million were charged to 2000.
As provided for in the Merger Agreement, NiSource organized a new company that
serves as the holding company for Columbia and its subsidiaries.

4. RESTRUCTURING ACTIVITIES

During 2000, Columbia developed and began the implementation of a plan to
restructure its operations as a result of the acquisition of Columbia by
NiSource. The restructuring plan included a severance program, a transition plan
to implement operational efficiency throughout Columbia's operations and a
voluntary early retirement program. During 2001, the restructuring initiative
was continued with the addition of a plan to restructure the operations within
the Distribution segment.


23


ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

During 2002, Columbia developed a new reorganization initiative, which resulted
in the elimination of approximately 200 positions throughout the organization
mainly affecting executive and other management-level employees. Columbia
accrued approximately $21.6 million of salaries and benefits associated with the
eliminated positions during 2002. As of December 31, 2002, 66 of the
approximately 200 employees were terminated.

For all of the plans, a total of approximately 1,000 management, professional,
administrative and technical positions have been identified for elimination. As
of December 31, 2002, approximately 780 employees had been terminated, of whom
approximately 328 employees were terminated during 2002. At December 31, 2002
and December 31, 2001, the consolidated balance sheets reflected liabilities of
$35.4 million and $31.4 million related to the restructuring plans,
respectively. During 2002 and 2001, $15.1 million and $10.7 million of benefits
were paid as a result of the restructuring plans, respectively. Additionally,
during 2002, the restructuring plan liability was reduced by $2.5 million due to
a reduction in estimated expenses related to previous reorganization
initiatives. The net pretax charge to earnings for 2002 was $19.1 million.
Columbia accrued approximately $10.8 million during 2001.

5. DISCONTINUED OPERATIONS

During the fourth quarter of 2002, Columbia decided to exit the
telecommunications business. The 2002 period included an after-tax impairment
charge of $51.3 million related to the continuing depressed market for dark
fiber and Columbia's decision to exit the telecommunications business. An
initial after-tax impairment related to the telecommunications business of $52.0
million was recorded in 2001 due to Columbia's determination that the carrying
value of the assets exceeded the realizable value. The results of operations
related to Columbia Transmission Communications Corporation (Transcom) are
displayed as discontinued operations for all periods presented and are reflected
as net assets and net liabilities of discontinued operations on the consolidated
balance sheet at December 31, 2002.

On August 21, 2001, Columbia sold the stock and assets of Columbia Propane to
AmeriGas Partners L.P. for approximately $196.0 million, consisting of $152.0
million in cash and $44.0 million of AmeriGas partnership common units. The loss
on the sale of Columbia Propane amounted to an after-tax loss of $50.6 million.
Columbia has also sold substantially all the assets of Columbia Petroleum
Corporation.

In the third quarter 2000, Columbia sold Columbia Energy Services Inc. (Columbia
Energy Services) Retail Mass Marketing business to The New Power Company. The
proceeds from the sale were $44.2 million. Columbia Energy Services ceased
operations of its Major Accounts business during the third quarter of 2000. As
of December 31, 2000, Columbia Energy Services' Wholesale and Trading
operations, Major Accounts and Retail Mass Markets businesses essentially ceased
all operations.

The loss from discontinued operations are provided in the following table:

6. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

SFAS NOS. 141 AND 142 - BUSINESS COMBINATIONS AND GOODWILL AND OTHER INTANGIBLE
ASSETS. In July 2001, the FASB issued Statement of Financial Accounting
Standards (SFAS) No. 141, "Business Combinations," and SFAS No. 142, "Goodwill
and Other Intangible Assets." The key requirements of the two interrelated
Statements include mandatory use of the purchase method of accounting for
business combinations, discontinuance of goodwill amortization, a revised
framework for testing for goodwill impairment at a "reporting unit" level, and
new criteria for the identification and potential amortization of other
intangible assets. Other changes to existing accounting standards involve the
amount of goodwill to be used in determining the gain or loss on the disposal of
assets and a requirement to test goodwill for impairment at least annually.

SFAS No. 141 is generally effective for combinations initiated after June 30,
2001. SFAS No. 142 is effective for fiscal years beginning after December 15,
2001.

Columbia adopted the provisions of SFAS No. 141 on July 1, 2001, and adopted
SFAS No. 142 on January 1, 2002. The statements had no impact on Columbia's
results of operations, as Columbia has no goodwill on its balance sheet.

SFAS NO. 143 - ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS. In July 2001, the
FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations" (SFAS
No. 143). SFAS No. 143 requires entities to record the fair value of a liability
for legally required asset retirement obligations in the period in which it is
incurred. When the liability is initially recorded, the entity capitalizes the
cost, thereby increasing the carrying amount of the related long-lived asset.
Over time, the liability is accreted, and the capitalized cost is depreciated
over the useful life of the related asset. The rate-regulated subsidiaries will
defer the difference between the amount recognized for depreciation and the
amount collected in rates as required pursuant to SFAS No. 71. Upon settlement
of the liability, an entity either settles the obligation for its recorded
amount or incurs a gain or loss. SFAS No. 143 is effective for Columbia
beginning January 1, 2003.

Columbia currently estimates that the adoption of SFAS No. 143 on January 1,
2003 will result in the recognition of total asset retirement obligation
liabilities of approximately $50.0 million. The combined amount for depreciation
and accretion for 2003 is estimated to total $4.0 million. Of this amount, $0.6
million is related to rate-regulated subsidiaries and will be deferred as a
regulatory asset. Columbia will also recognize a charge of $0.2 million for
asset retirement obligations associated with the telecommunications network.


25


ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Columbia undertook an effort to identify the assets impacted by SFAS No. 143,
align the assets with types of asset retirement obligations and develop a plan
for measurement of the obligations for each asset group. Retirement obligations
were identified at each of the business segments.

For the Distribution segment, the groups of assets reviewed for retirement
obligations include distribution and service pipelines (almost all of which are
on permanent easements), gas meters, underground gas storage facilities, propane
gas facilities and underground storage tanks. Although the pipelines,
underground gas storage facilities, propane gas facilities and underground
storage tanks on owned property have certain legal obligations to remove the
assets upon retirement, the lives of the assets are presently indeterminate and,
therefore, the liabilities are not quantifiable. Regulatory requirements in
certain states require a particular number or percentage of meters be removed
each year. The meters may be refurbished and reused or disposed of. No legal
obligation exists to dispose of the removed meters; therefore, no liability
would be recognized related to retirement obligations for meters. For
underground gas storage tanks on leased property, where a determinate life
exists, the cost to remove and dispose of the tanks is minimal.

Transmission and Storage segment assets include pipelines, storage fields and
wells, storage tanks, compressor stations and offshore pipeline and platform
facilities in the Gulf of Mexico. From an operational viewpoint, the onshore
pipelines, related compressor stations and storage fields and wells presently
have indeterminate lives and, therefore, the liabilities related to retirement
obligations are not quantifiable. The compressor stations have legal obligations
associated with their retirement involving the removal of facilities. The
pipeline facilities are generally on land leased through permanent easements,
which are silent with regard to removal. The pipelines are generally retired in
place. Retirement obligations are quantifiable for the removal of facilities
related to certain storage fields where Federal Energy Regulatory Commission
(FERC) approval for abandonment has been obtained and compressor stations that
have been shut down. Obligations to remove offshore platforms and cut, cap and
fill offshore pipelines exist upon retirement, and hence are covered by SFAS No.
143.

The Exploration and Production segment has retirement obligations for compressor
stations, wells and well pipelines on either owned or leased land, treatment and
injection facilities and disposal wells. The compressor stations presently have
indeterminate lives; therefore an estimate of the liability for the associated
retirement obligations is not calculable. The other facilities generally have
determinate lives and liabilities will be measured for the estimated retirement
obligations. Columbia estimates that most of the retirement obligations
associated with its assets will be related to exploration and production assets
primarily due to the large number of wells.

SFAS NO. 146 - ACCOUNTING FOR COSTS ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES.
In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities." The Statement addresses financial accounting
and reporting for costs associated with exit or disposal activities and
nullifies EITF Issue No. 94-3, "Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (including Certain
Costs Incurred in a Restructuring)" (EITF No. 94-3). The standard will be
effective for exit or disposal activities initiated after December 2002.
Columbia does not expect the Statement to have a material effect on its
financial condition or results of operations. The costs associated with
Columbia's restructuring plans initiated in 2002 were recorded in conformity
with EITF No. 94-3.

FASB INTERPRETATION NO. 45 - GUARANTOR'S ACCOUNTING AND DISCLOSURE REQUIREMENTS
FOR GUARANTEES, INCLUDING INDIRECT GUARANTEES OF INDEBTEDNESS OF OTHERS. In
November of 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting
and Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others" (FIN 45). FIN 45 elaborates on the disclosures to be
made by a guarantor in its interim and annual financial statements about its
obligations under certain guarantees that it has issued. It also clarifies that
a guarantor is required to recognize, at the inception of a guarantee, a
liability for the fair value of the obligation undertaken in issuing the
guarantee. The initial recognition and initial measurement provisions of FIN 45
are applicable on a prospective basis to guarantees issued or modified after
December 31, 2002. The disclosure requirements in FIN 45 are effective for
financial statements of interim or annual periods ending after December 15,
2002. Columbia does not expect FIN 45 to have a material impact on its financial
position or results of operations. Refer to "Other Commitments and Contingencies
- - Guarantees and Indemnities" in Note 15D for further discussion of Columbia's
guarantees.

7. RISK MANAGEMENT ACTIVITIES

Columbia is exposed to market risk due to fluctuations in commodity prices,
primarily at its exploration and production subsidiary. Columbia uses
commodity-based derivative financial instruments to manage certain risks in its
business. Columbia accounts for its derivatives under SFAS No. 133. Financial
instruments authorized for use by Columbia for hedging include futures, swaps
and options. Columbia is also exposed to interest rate risk and has entered into
interest rate swaps to hedge a portion of the interest rate risk associated with
its long-term debt.

The activity for the years 2002 and 2001 affecting other comprehensive income,
with respect to cash flow hedges included the following:

Unrealized gains and losses on Columbia's hedges were recorded as price risk
management assets and liabilities. The accompanying Consolidated Balance Sheets
reflected price risk management assets related to unrealized gains and losses on
hedges of $138.4 million and $65.3 million at December 31, 2002 and 2001,
respectively, of which $25.5 million and $15.1 million were included in "Current
Assets" and $112.9 million and $50.2 million were included in "Other Assets."
Price risk management liabilities related to unrealized gains and losses on
hedges of $8.5 million and $4.8 million at December 31, 2002 and 2001,
respectively, were included in "Current Liabilities."

During 2002 and 2001, a net loss of $0.7 million and a net gain of $0.7 million,
net of tax, was recognized in earnings due to the change in value of certain
derivative instruments primarily representing time value, and there were no
components of the derivatives' fair values excluded in the assessment of hedge
effectiveness. Also during 2002 and 2001, Columbia reclassified $3.1 million and
$2.4 million related to its cash flow hedges of natural gas production from
other comprehensive income to earnings, due to the probability that certain
forecasted transactions would not occur. It is anticipated that during the next
twelve months the expiration and settlement of cash flow hedge contracts will
result in income recognition of amounts currently classified in other
comprehensive income of approximately $12.3 million, net of tax.

For regulatory incentive purposes, the Columbia distribution subsidiaries
(Columbia LDCs) enter into contracts that allow counterparties the option to
sell gas to Columbia LDCs at first of the month prices for a particular month of
delivery. Columbia LDCs charge the counterparties a fee for this option. The
changes in the fair value of the options are primarily due to the changing
expectations of the future intra-month volatility of gas prices. Columbia LDCs
defer a portion of the change in the fair value of the options as either a
regulatory asset or liability in accordance with SFAS No. 71. The remaining
change is recognized currently in earnings.

CNR has engaged in commodity and basis swaps to hedge the anticipated future
sale of natural gas. These contracts are derivatives and are designated as cash
flow hedges of anticipated future sales.

Columbia Energy Services, Inc. (Columbia Energy Services) has fixed price gas
delivery commitments to three municipalities in the United States. Columbia
Energy Services entered into a forward purchase agreement with a gas supplier,
wherein the supplier will fulfill the delivery obligation requirements at a
slight premium to index. In order to hedge this anticipated future physical
purchase of gas from the gas supplier, Columbia Energy Services entered into
commodity swaps priced at the locations designated for physical delivery. These
swaps are designated as cash flow hedges of the anticipated purchases.

Columbia has entered into interest rate swap agreements to modify the interest
characteristics of its outstanding long-term debt. The effect of these
agreements is to modify the interest rate characteristics of a portion of
Columbia's long-term debt from fixed to variable. On September 3, 2002, Columbia
entered into new fixed-to-variable interest rate swap agreements for a combined
notional amount of $281.5 million with three counterparties effective as of
September 5, 2002. Columbia will receive payments based upon a fixed 7.32%
interest rate and pay a floating interest amount based on U.S. 6-month LIBOR-BBA
plus 2.66 percent per annum. There was no exchange of premium at inception of
the swaps. The swaps contain mirror-image call provisions that allow the
counterparties to cancel the agreements beginning November 28, 2005 through the
stated maturity date. In addition, each party has the one-time right to cancel
the swaps on September 5, 2007.

As a result of the interest rate swap transactions; $663.0 million of Columbia's
long-term debt is now subject to fluctuations in interest rates. The interest
rate swaps are designated as fair value hedges. The effectiveness of the
interest rate swaps in offsetting the exposure to changes in the debt's fair
value is measured using the short-cut method pursuant to SFAS No. 133. Columbia
had no net gain or loss recognized in earnings due to ineffectiveness during
2002 or 2001.

10. PENSION AND OTHER POSTRETIREMENT BENEFITS

Columbia has a noncontributory, qualified defined benefit pension plan covering
essentially all employees. Benefits are based primarily on years of credited
service and employees' highest three-year average annual compensation in the
final five years of service. Effective January 1, 2000, Columbia adopted a cash
balance feature to the pension plan that provides benefits based on a
percentage, which may vary with age and years of service, of current eligible
compensation and current interest credits. Columbia's funding policy complies
with Federal law and tax regulations. In addition, Columbia has a nonqualified
pension plan that provides benefits to some employees in excess of the qualified
plan's Federal tax limits. Columbia also provides medical coverage and life
insurance to retirees. Essentially all active employees are eligible for these
benefits upon retirement after completing ten consecutive years of service after
age 45. Normally, spouses and dependents of retirees are also eligible for
medical benefits. Columbia is reflecting the information presented below as of
September 30, rather than December 31. The effect of utilizing September 30,
rather than December 31, is not significant.

Due to the decline in the equity markets, the fair value of Columbia's pension
fund assets has decreased since September 30, 2001. In addition, the discount
rate used to measure the accumulated benefit obligation has decreased, resulting
in an increase in the estimated minimum liability. In accordance with SFAS No.
87, "Employers' Accounting for Pensions," Columbia recorded a minimum pension
liability adjustment at September 30, 2002. The adjustment resulted in a
decrease to prepaid pension costs of $28.9 million, an increase in intangible
assets of $2.3 million, an increase to retirement benefit liabilities of $5.7
million, an increase to deferred income tax assets of $12.3 million, and a
decrease to other comprehensive income of $20.0 million after-tax. Also,
Columbia expects pension expense for 2003 to increase approximately $12.0
million over the amount recognized in 2002.

In 2001, Columbia recorded a reduction in its pension benefit obligation
amounting to $23.9 million due to the finalization of the number of employees
who elected to convert to an account balance plan from the previous final pay
benefit structure. Columbia recorded curtailment gains to net periodic benefits
costs in 2001 amounting to $3.3 million and $8.9 million for pensions and other
benefits, respectively, related to the reduction in future benefit accruals
associated with employees of Columbia Propane. Also, in 2001 a settlement gain
of $8.4 million was recorded related to terminated employees who elected to
receive lump-sum payments from the pension plan.

The following tables provide a reconciliation of the plan's funded status and
amounts reflected in Columbia's consolidated balance sheets at December 31 based

Columbia has entered into interest rate swap agreements to modify the interest
characteristics of its outstanding long-term debt. Under the terms of the swap
agreements, Columbia pays interest based on a floating rate index and receives
interest based on a fixed rate. The effect of these agreements is to modify the
interest rate characteristics of a portion of Columbia's long-term debt from
fixed to variable and to hedge the fair value of the underlying debt. On
September 3, 2002, Columbia entered into "receive fixed" and "pay floating"
interest rate swap agreements totaling $281.5 million with three counterparties
effective as of September 5, 2002. According to the agreements, Columbia will
receive payments based upon a fixed 7.32% interest rate and will pay a floating
interest amount based on U.S. 6-month LIBOR-BBA plus 2.66% per annum. In total,
Columbia has entered into fixed-to-variable interest rate swaps on $663.0
million of its long-term debt.

13. SHORT-TERM DEBT AND CREDIT FACILITIES

At the beginning of 2001, Columbia had two unsecured bank revolving credit
facilities available that totaled $900 million (Credit Facilities). The Credit
Facilities consisted of a 364-day facility totaling $850 million and a two-year
facility totaling $50 million. The Credit Facilities were terminated during 2001
and replaced with NiSource revolving credit facilities.

At December 31, 2002, Columbia had $136.4 million of affiliated short-term
borrowings from the NiSource Money Pool at a weighted average interest rate of
2.1%.

At December 31, 2002, approximately $20.7 million of investments were pledged as
collateral on outstanding letters of credit related to Columbia's wholly owned
insurance company.

14. FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate fair
value:

INVESTMENTS. Where feasible, the fair value of investments is estimated based on
market prices for those or similar investments.

LONG-TERM DEBT. The fair values of these securities are estimated based on the
quoted market prices for the same or similar issues or on the rates offered for
securities of the same remaining maturities. Certain premium costs associated
with the early settlement of long-term debt are not taken into consideration in
determining fair value.

The carrying values and estimated fair values of financial instruments were as
follows:



CARRYING ESTIMATED Carrying Estimated
AMOUNT FAIR VALUE Amount Fair Value
At December 31, ($ in millions) 2002 2002 2001 2001

Long-term investments 15.5 15.0 5.0 4.8
Long-term debt (including current portion) 1,388.0 1,485.1 1,639.1 1,677.3
---------- ---------- ---------- ----------


The long-term debt relates to utility operations. The utilities are subject to
regulation and gains or losses may be included in rates over a prescribed
amortization period, if in fact settled at amounts approximating those above.

In October 1999, Columbia of Ohio entered into an agreement to sell, without
recourse, a majority of its trade accounts receivable to Columbia Accounts
Receivable Corporation (CARC), a wholly-owned subsidiary of Columbia. At the
same time, CARC entered into an agreement, with a third party, Canadian Imperial
Bank of Commerce, to sell a percentage ownership interest in a defined pool of
accounts receivable (Sales Program). Under the Sales Program, CARC can transfer
an undivided interest in a designated pool of its accounts receivable on an
ongoing basis up to a maximum of $200.0 million, $75.0 million or $50.0 million,
as determined by the seasonal fluctuation in Columbia of Ohio's account
receivable balances and the mutual consent of both parties. The amount available
at any measurement date varies based upon the level of eligible receivables.
Under this agreement, approximately $99.5 million of receivables were sold as of
December 31, 2002.

Columbia's accounts receivable programs qualify for sale accounting based upon
the conditions met in SFAS No. 140 "Accounting for Transfers and Servicing of
Financial Asset and Extinguishments of Liabilities." In the agreements, all
transferred assets have been isolated from the transferor and put presumptively
beyond the reach of the transferor and its creditors, even in bankruptcy or
other receivership. Columbia does not retain any interest in the receivables.

15. OTHER COMMITMENTS AND CONTINGENCIES

A. CAPITAL EXPENDITURES. Capital expenditures for 2003 are currently estimated
at $335.0 million. Of this amount, $118.0 million is for the distribution
operations and $134.5 million is for the transmission and storage operations.
The remainder is for maintaining production levels at the exploration and
production operations.

B. OTHER LEGAL PROCEEDINGS. In the normal course of its business, Columbia and
its subsidiaries have been named as defendants in various legal proceedings. In
the opinion of management, the ultimate disposition of these currently asserted
claims would not have a material adverse impact on Columbia's consolidated
financial position or results of operations.

C. ASSETS UNDER LIEN. Substantially all of Columbia Gas Transmission
Corporation's (Columbia Transmission) properties have been pledged to Columbia
as security for debt owed by Columbia Transmission to Columbia.

D. GUARANTEES AND INDEMNITIES. As a part of normal business, Columbia and
certain subsidiaries enter into various agreements providing financial or
performance assurance to third parties on behalf of certain subsidiaries. These
agreements are entered into primarily to support or enhance the creditworthiness
otherwise attributed to a subsidiary on a stand-alone basis, thereby
facilitating the extension of sufficient credit to accomplish the subsidiaries'
intended commercial purposes. The total commercial commitments in existence at
December 31, 2002 and the years in which they expire were:

-------- -------- -------- -------- -------- --------
Total commercial commitments $ 144.0 $ -- $ 112.2 $ 977.8 $ 47.9 $ 290.6
-------- -------- -------- -------- -------- --------


Columbia has issued guarantees, which support up to approximately $1.3 billion
in commodity-related payments for its subsidiaries involved in forward gas sales
activities. These guarantees were provided to counterparties in order to
facilitate physical and financial transactions. To the extent liabilities exist
under the commodity-related contracts subject to these guarantees, such
liabilities are included in the consolidated balance sheets.

Columbia has also guaranteed purchase and sale agreements guarantees totaling
$142.5 million, which guarantee performance of seller's covenants, agreements,
obligations, liabilities, representations and warranties under the agreements.
No amounts related to the purchase and sale agreement guarantees are reflected
in the consolidated balance sheet.

Management believes that the likelihood Columbia would be required to perform or
otherwise incur any significant losses associated with any of these guarantees
is remote.

E. INTERNAL REVENUE SERVICE (IRS) AUDIT. The Revenue Agent's Report for years
1996 and 1997, issued on January 28, 2002, was revised and reissued on December
10, 2002 following subsequent negotiations with the IRS. These negotiations
resulted in settlement of all remaining issues. A payment of $7.9 million was
made to the United States Treasury on December 23, 2002 in settlement of tax and
interest related to those issues. The audit of Columbia's 1998 through 2000 tax
years, which started on February 19, 2002, continues and is expected to be
completed before the end of 2003. Management believes adequate reserves have
been established for issues related to these returns.

F. ENVIRONMENTAL MATTERS.

GENERAL. Columbia's subsidiaries are subject to extensive federal, state and
local laws and regulations relating to environmental matters. These laws and
regulations, which are constantly changing, require expenditures for corrective
action at various operating facilities, waste disposal sites and former gas
manufacturing sites for conditions resulting from past practices that have
subsequently become subject to environmental regulation. Columbia's subsidiaries
have implemented programs to continually review compliance with existing
environmental standards and have reviewed past operational activities and
conducted remediation programs where necessary.

DISTRIBUTION OPERATIONS. Several Distribution subsidiaries are "potentially
responsible parties" (PRPs) at waste disposal sites under the Comprehensive
Environmental Response Compensation and Liability Act (CERCLA) (commonly known
as Superfund) and similar state laws, including at former manufactured gas plant
(MGP) sites which such subsidiaries, or their corporate predecessors, own or
previously owned or operated. Distribution subsidiaries may be required to share
in the cost of clean up of such sites. In addition, some Distribution
subsidiaries have corrective action liability under the Resource Conservation
and Recovery Act (RCRA) for closure and clean-up costs associated with
underground storage tanks and under the Toxic Substances Control Act for clean
up of polychlorinated biphenyls released at various facilities.

Distribution subsidiaries are parties to or otherwise involved in clean up of
three waste disposal sites under Superfund or similar state laws. For one of
these sites the potential liability is de minimis and, for the other two, the
final costs of clean up have not yet been determined. As site investigations and
clean-ups proceed and as additional information becomes available, the waste
disposal site liability is reviewed and adjusted, as necessary.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

A program has been instituted to identify and investigate former MGP sites where
Distribution subsidiaries or predecessors are the current or former owner. The
program has identified 84 such sites. Initial investigation has been conducted
at 40 sites. Of these sites, additional investigation activities have been
completed or are in progress at 34 sites and remedial measures have been
implemented or completed at 19 sites. Only those site investigation,
characterization and remediation costs currently known and determinable can be
considered "probable and reasonably estimable" under SFAS No. 5, "Accounting for
Contingencies". As costs become probable and reasonably estimable, reserves will
be adjusted as appropriate. As reserves are recorded, regulatory assets are
recorded to the extent environmental expenditures are expected to be recovered
through rates. Columbia is unable, at this time, to accurately estimate the time
frame and potential costs of the entire program. Management expects that, as
characterization is completed, additional remediation work is performed and more
facts become available, Columbia will be able to develop a probable and
reasonable estimate for the entire program or a major portion thereof consistent
with the Securities and Exchange Commission's Staff Accounting Bulletin No. 92
(SAB No. 92) which covers accounting and disclosures relating to loss
contingencies, SFAS No. 5, and American Institute of Certified Public
Accountants SOP 96-1, "Environmental Remediation Liabilities" (SOP No.96-1).

As of December 31, 2002, a reserve of approximately $43.6 million has been
recorded to cover probable environmental response actions. The ultimate
liability in connection with these sites will depend upon many factors,
including the volume of material contributed to the site, years of ownership or
operation, the number of other PRPs and their financial viability and the extent
of environmental response actions required. Based upon investigations and
management's understanding of current environmental laws and regulations,
Columbia believes that any environmental response actions required, after
consideration of insurance coverage, contributions from other PRPs and rate
recovery, will not have a material effect on its financial position.

TRANSMISSION AND STORAGE OPERATIONS. Columbia Transmission continues to conduct
characterization and remediation activities at specific sites under a 1995
Environmental Protection Agency (EPA) Administrative Order by Consent (AOC). The
program pursuant to the AOC covers approximately 240 facilities, approximately
13,000 liquid removal points, approximately 2,200 mercury measurement stations
and about 3,700 storage well locations. Field characterization had been
performed at all sites. Site characterization reports and remediation plans,
which must be submitted to the EPA for approval, are in various stages of
development and completion. Remediation has been completed at the mercury
measurement stations, liquid removal point sites and storage well locations and
at a number of the 240 facilities.

Only those site investigation, characterization and remediation costs currently
known and determinable can be considered "probable and reasonably estimable"
under SFAS No. 5. As costs become probable and reasonably estimable, the
associated reserves will be adjusted as appropriate. As of September 30, 2002,
Columbia Transmission completed a sufficient number of the characterization
reports and remediation plans to adjust its original estimate for the entire
program. As a result, the liability was reduced by $15.5 million. The estimate
may be adjusted as additional work is completed consistent with SAB No. 92, SFAS
No. 5, and SOP No. 96-1.

Columbia Transmission and Columbia Gulf are PRPs at several waste disposal
sites. The potential liability is believed to be de minimis, however, the final
allocation of clean-up costs has yet to be determined. As site investigations
and clean-ups proceed and as additional information becomes available, waste
disposal site liability is reviewed periodically and adjusted.

At December 31, 2002, the remaining environmental liability recorded on the
balance sheet of Transmission was $61.3 million. Future expenditures will be
charged against the previously recorded liability. A regulatory asset has been
recorded to the extent environmental expenditures are expected to be recovered
through rates. Management does not believe that Columbia Transmission's
environmental expenditures will have a material adverse effect on Columbia's
operations, liquidity or financial position, based on known facts, existing
laws, regulations, Columbia Transmission's cost recovery settlement with
customers and the time period over which expenditures will be made.

DISCONTINUED OPERATIONS. Columbia affiliates have retained environmental cleanup
liability associated with some of its former operations including those of
propane, petroleum and certain local distribution companies. The most
significant environmental liability relates to a former MGP site. The remainder
of the liability is associated with former petroleum operations.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

COLUMBIA ENERGY GROUP AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

The ultimate liability in connection with these sites will depend upon many
factors including the extent of environmental response actions required, other
PRPs and their financial viability, and indemnification from previous facility
owners. Only those corrective action costs currently known and determinable can
be considered "probable and reasonably estimable" under SFAS No. 5 and
consistent with SOP No. 96-1. As costs become probable and reasonably estimable,
reserves will be adjusted as appropriate. Columbia believes that any
environmental response actions required at former operations, for which it is
ultimately liable, after consideration of insurance coverage and contributions
from other PRPs, will not have a material adverse effect on Columbia's financial
position.

ENVIRONMENTAL RESERVES. It is management's continued intent to address
environmental issues in cooperation with regulatory authorities in such a manner
as to achieve mutually acceptable compliance plans. However, there can be no
assurance that fines and penalties will not be incurred. Management expects most
environmental assessment and remediation costs to be recoverable through rates
for certain Columbia companies.

As of December 31, 2002, a reserve of approximately $108.8 million has been
recorded to cover probable corrective actions at sites where Columbia has
environmental remediation liability. The ultimate liability in connection with
these sites will depend upon many factors, including the volume of material
contributed to the site, the number of the other PRPs and their financial
viability, the extent of corrective actions required and rate recovery. Based
upon investigations and management's understanding of current environmental laws
and regulations, Columbia believes that any corrective actions required, after
consideration of insurance coverages, contributions from other PRPs and rate
recovery, will not have a material effect on its financial position or results
of operations.

G. OPERATING LEASES. Payments made in connection with operating leases are
primarily charged to operation and maintenance expense as incurred. Such amounts
were $31.5 million in 2002, $32.6 million in 2001 and $71.6 million in 2000.

Future minimum rental payments required under operating leases that have initial
or remaining noncancellable lease terms in excess of one year are:

H. PURCHASE COMMITMENTS. Columbia has service agreements that provide for
pipeline capacity, transportation and storage services. These agreements, which
have expiration dates ranging from 2003 to 2014, provide for Columbia to pay
fixed monthly charges. The estimated aggregate amounts of such payments at
December 31, 2002, were:

19. SEGMENTS OF BUSINESS

Columbia is a registered holding company under the Public Utility Holding
Company Act of 1935, as amended, and derives substantially all of its revenues
and earnings from the operating results of its 18 direct subsidiaries.
Columbia's operations are divided into four primary business segments. The
Distribution segment provides natural gas service and transportation for
residential, commercial and industrial customers in Ohio, Pennsylvania,
Virginia, Kentucky and Maryland. The Transmission and Storage segment offers
transportation and storage services for local distribution companies, marketers
and industrial and commercial customers located in northeastern, mid-Atlantic,
midwestern and southern states and the District of Columbia. The Exploration and
Production segment explores for, develops, produces and markets gas and oil in
the United States. The Other segment is primarily comprised of the remaining gas
sales obligation of Columbia Energy Services, which was in the commercial and
residential natural gas retail business, and the operations of the remaining
microwave relay business. The dark-fiber optics telecommunications network was
moved from other to discontinued operations in 2002. All prior periods were
adjusted to reflect this change.

Future cash inflows are computed by applying year-end prices to estimated future

year-end costs) represent those costs to be incurred in developing and producing
the reserves. Discounted future net cash flows are derived by applying a 10%
discount rate, as required by the Financial Accounting Standards Board, to the
future net cash flows. This data is not intended to reflect the actual economic
value of Columbia's gas and oil producing properties or the true present value
of estimated future cash flows since many arbitrary assumptions are used. The
data does provide a means of comparison among companies through the use of
standardized measurement techniques.
