C.   Capital Stock

On January 18, 2001, the Company's Board of Directors approved, and on May 17,
2001, the shareholders of the Company voted in favor of, a two-for-one common
stock split, which was effected through the issuance of one additional share of
common stock for each share of common stock outstanding to holders of record on
May 23, 2001, with distribution of the shares on June 11, 2001.  The Company
retained the current par value of $.01 per share for all shares of common stock.
Shareholders' equity reflects the stock split by reclassifying from Paid in
Capital to Common Stock an amount equal to the cumulative par value of the
additional shares issued to effect the split.  All share and per share amounts
contained herein for all periods presented reflect this stock split.
Outstanding convertible preferred stock is assumed to convert to common stock on
a two-for-one basis in the calculations of earnings per share.

E.  Earnings per Share Information

In accordance with an announcement of the Financial Accounting Standards Board's
Staff at the Emerging Issues Task Force meeting in April 2001, codified as EITF
Topic No. D-95 (Topic D-95), the Company revised its computation of earnings per
common share (EPS). In accordance with Topic D-95, the dilutive effect of the
Company's Series A Convertible Preferred Stock is now considered in the
computation of basic EPS, utilizing the "if-converted" method. Under the
Company's "if-converted" method, the dilutive effect of the Series A Convertible
Preferred Stock on EPS cannot be less than the amount that would result from the
application of the "two-class" method of computing EPS. The "two-class" method
is an earnings allocation formula that determines EPS for the common stock and
the participating Series A Convertible Preferred Stock according to dividends
declared and participating rights in the undistributed earnings. The Series A
Convertible Preferred Stock is a participating instrument with the Company's
common stock with respect to the payment of dividends. For all periods
presented, the "two-class" method resulted in additional dilution. Accordingly,
EPS for such periods reflects this further dilution. The Company restated the
EPS amounts for the three and six months ended June 30, 2000 to be consistent
with the revised methodology.

The following is a reconciliation of the basic and diluted EPS computations.

F.    Commitments and Contingencies

In connection with the now terminated proposed acquisition of Southwest Gas
Corporation (Southwest), the Company is party to various lawsuits.  These
lawsuits originally contained allegations that included, but were not limited
to, federal and state Racketeer Influenced and Corrupt Organizations (RICO) Act
violations and improper interference in a contractual or other business
relationship between Southwest and Southern Union Corporation (Southern Union).
Southern Union's complaint originally asked for $750 million damages to be
trebled for alleged RICO violations, compensatory damages of not less than $750
million, punitive damages, and rescission of the Confidentiality and Standstill
Agreement.  On May 21, 2001, the Court denied Southern Union's motion to
reconsider its ruling dismissing the federal RICO claims against the Company or
to enter a judgment on the ruling.  The Court also applied its ruling to dismiss
the state RICO claim asserted by Southern Union against the Company.  The
Court's ruling on the RICO claims were made applicable to all defendants. On
June 21, 2001, the Court dismissed with prejudice Southern Union's claim for
fraudulent inducement against the Company, Gene Dubay and John Gaberino.  The
Court did not dismiss the claim by Southern Union against Southwest and Michael
Maffie. The Court also dismissed with prejudice Southern Union's claims for
tortious interference with a contractual relationship against the Company.  This
claim remains pending against only Gene Dubay, John Gaberino, James Irvin and
Jack Rose.  The Court denied the motion to dismiss Southern Union's claim for
tortious interference with a prospective relationship against the Company, Gene
Dubay and John Gaberino.  On June 29, 2001, the Company filed a motion for
summary judgment in its favor on the sole remaining claim asserted against it by
Southern Union.  Various other motions for summary judgment were filed by other
parties, all of which are scheduled for hearing on August 24, 2001.

The Company, as third party beneficiary, has filed a lawsuit against Southern
Union for, among other things, breach of a confidentiality agreement with
Southern Union and Southwest and tortious interference with the Southwest merger
agreement.  The Company filed suit against Southwest seeking a declaratory
judgment determining that it had properly terminated the merger agreement.  In
response to this suit, Southwest brought a suit against the Company and Southern
Union alleging, among other things, fraud and breach of contract.  Southwest is
seeking damages in excess of $75,000.

Most of the lawsuits discussed above have been consolidated into one case with
ONEOK being designated as the plaintiff regarding claims against Southern Union.
The court has entered an order setting the cases for jury trial on November 12,
2001.

                                       11


Two substantially identical derivative actions were filed by shareholders
against the members of the Board of Directors of the Company for alleged
violation of their fiduciary duties to the Company by causing or allowing the
Company to engage in certain fraudulent and improper schemes designed to
"sabotage" Southern Union Company's competitive bid to acquire Southwest and
secure regulatory approval for the Company's own planned merger with Southwest.
Such conduct allegedly caused the Company to be sued by both Southwest and
Southern Union, which exposed the Company to millions of dollars in liabilities.
The allegations are used as a basis for causes of action for intentional breach
of fiduciary duty, derivative claim for negligent breach of fiduciary duty,
class and derivative claims for constructive fraud, and derivative claims for
gross mismanagement.  Each plaintiff seeks a declaration that the lawsuit is
properly maintained as a derivative action, the defendants, and each of them,
have breached their fiduciary duties to the Company, an injunction permanently
enjoining defendants from further abuse of control and committing of gross
mismanagement and constructive fraud, and asks for an award of compensatory and
punitive damages and costs, disbursements and reasonable attorney fees. A Joint
Motion for Consolidation of both derivative actions was filed on June 6, 2000,
and Pretrial Order No. 1 was entered on that date consolidating the actions and
establishing a schedule for response to a consolidated petition.  On July 21,
2000, the plaintiffs filed their Consolidated Petition.  Stephen J. Jatras and
J.M. Graves have been eliminated as defendants in the Consolidated Petition, but
Eugene Dubay was added as a new defendant.  The plaintiffs also dropped their
class and derivative claim for constructive fraud, but added a new derivative
claim for waste of corporate assets.  On September 19, 2000, the Company, the
Independent Directors (Anderson, Bell, Cummings, Ford, Fricke, Lake, Mackie,
Newsom, Parker, Scott and Young), David Kyle, and Gene Dubay filed Motions to
Dismiss the action for failure of the plaintiffs to make a pre-suit demand on
the Company's Board of Directors.  In addition, the Independent Directors, David
Kyle, and Gene Dubay filed Motions to Dismiss the Plaintiffs' Consolidated
Petition for failure to state a claim.  On January 3, 2001, the Court dismissed
the action without prejudice as to its claims against Larry Brummett. On
February 26, 2001, the action was stayed until one of the parties notifies the
Court that a dissolution of the stay is requested.

If any of the plaintiffs should be successful in any of their claims against the
Company and substantial damages are awarded, it could have a material adverse
effect on the Company's operations, cash flow, and financial position.  At the
present time, the Company is unable to estimate the possible loss, if any,
associated with these matters.  The Company is defending itself vigorously
against all claims asserted by Southern Union and Southwest and all other
matters relating to the now terminated proposed acquisition with Southwest.

The Company has responsibility for 12 manufactured gas sites located in Kansas,
which may contain coal tar and other potentially harmful materials that are
classified as hazardous material.  Hazardous materials are subject to control or
remediation under various environmental laws and regulations. A consent
agreement with the Kansas Department of Health and Environment (KDHE) presently
governs all future work at these sites.  The terms of the consent agreement
allow the Company to investigate these sites and set remediation priorities
based upon the results of the investigations and risk analysis.  The prioritized
sites will be investigated over a ten year period.  At March 31, 2001, the costs
of the investigations and risk analysis have been immaterial. Limited
information is available about the sites and no testing has been performed.
Management's best estimate of the cost of remediation ranges from $100 thousand
to $10 million per site based on a limited comparison of costs incurred to
remediate comparable sites.  These estimates do not give effect to potential
insurance recoveries, recoveries through rates or from third parties.  The
Kansas Corporation Commission (KCC) has permitted others to recover their
remediation costs through rates.  It should be noted that additional information
and testing could result in costs significantly below or in excess of the
amounts estimated above.  To the extent that such remediation costs are not
recovered, the costs could be material to the Company's results of operations
and cash flows depending on the degree of remediation required and number of
years over which the remediation must be completed.

The Oklahoma Corporation Commission (OCC) staff recommended to the OCC that
ONG's unrecovered purchased gas cost  (UPGC) clause be suspended because ONG
allegedly failed to "act prudently" in acquiring its gas supply for the
2000/2001 heating season resulting in an alleged $72.1 million in excess charges
to ratepayers through March 31, 2001.  The hearing on the merits of the OCC's
case was conducted on June 25-27, 2001, after which the OCC took the matter
under advisement.  ONG and the OCC submitted proposed orders on July 13, 2001.
If the OCC staff is successful, the Company would not be allowed to recover
approximately $72.1 million in UPGC.  The Company believes that the OCC staff's
recommendation is without merit and is defending itself vigorously against this
recommendation.

Two separate class action lawsuits have been filed against the Company in
connection with the natural gas explosions and eruptions of natural gas geysers
that occurred in Hutchinson, Kansas in January, 2001.  Although no assurances
can be given, management believes that the ultimate resolution of these matters
will not have a material adverse effect on its financial position or results of
operations.  The Company is vigorously defending itself against all claims.

The Company is a party to other litigation matters and claims, which are normal
in the course of its operations, and while the results of litigation and claims
cannot be predicted with certainty, management believes the final outcome of
such matters will not have a materially adverse effect on consolidated results
of operations, financial position, or liquidity.

G.  Segments

The Company conducts its operations through seven segments: (1) the Marketing
and Trading segment markets natural gas to wholesale and retail customers; (2)
the Gathering and Processing segment gathers and processes natural gas and
fractionates, stores and markets natural gas liquids; (3) the Transportation and
Storage segment transports and stores natural gas for others and buys and sells
natural gas; (4) the Distribution segment distributes natural gas to
residential, commercial and industrial customers, leases pipeline capacity to
others and provides transportation services for end-use customers; (5) the
Production segment develops and produces natural gas and oil;  (6) the Power
segment produces and sells electricity during peak periods to wholesale
customers; and (7) the Other segment primarily operates and leases the Company's
headquarters building and a related parking facility.

Intersegment sales are recorded on the same basis as sales to unaffiliated
customers.  All corporate overhead costs relating to a reportable segment have
been allocated for the purpose of calculating operating income.  The Company's
equity method investments do not represent operating segments of the Company.
The Company has no single external customer from which it receives ten percent
or more of its revenues.

H.    Paid in Capital

Paid in capital was $337.1 million and $331.2 million for common stock at June
30, 2001, and December 31, 2000, respectively.   Paid in capital for convertible
preferred stock was $564.2 million at June 30, 2001 and December 31, 2000.

I.    Derivative Instruments and Hedging Activities

On January 1, 2001, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (Statement 133), amended by Statement No. 137  and Statement No.
138.   Statement 137 delayed the implementation of Statement 133 until fiscal
years beginning after June 15, 2000.  Statement 138 amended the accounting and
reporting standards of Statement 133 for certain derivative instruments and
hedging activities.  Statement 138 also amends Statement 133 for decisions made
by the Financial Accounting Standards Board (FASB) relating to the Derivatives
Implementation Group (DIG) process. The FASB DIG is addressing Statement 133
implementation issues, the ultimate resolution of which may impact the
application of Statement 133.

Under Statement 133, entities are required to record all derivative instruments
in the balance sheet at fair value.  The accounting for changes in the fair
value of a derivative instrument depends on whether it has been designated and
qualifies as part of a hedging relationship and, if so, on the reason for
holding it.  If certain conditions are met, entities may elect to designate a
derivative instrument as a hedge of exposures to changes in fair values, cash
flows, or foreign currencies.  If the hedged exposure is a fair value exposure,
the gain or loss on the derivative instrument is recognized in earnings in the
period of change together with the offsetting loss or gain on the hedged item
attributable to the risk being hedged.  If the hedged exposure is a cash flow
exposure, the effective portion of the gain or loss on the derivative instrument
is reported initially as a component of other comprehensive income (outside
earnings) and subsequently reclassified into earnings when the forecasted
transaction affects earnings.  Any amounts excluded from the assessment of hedge
effectiveness, as well as the ineffective portion of the hedge, are reported in
earnings immediately.

                                       15


In 2000, the Company entered into derivative instruments related to the
production of natural gas, most of which will expire by the end of 2001.  These
derivative instruments are designed to hedge the Production segment's exposure
to changes in the price of natural gas.  Changes in the fair value of the
derivative instruments are reflected initially in other comprehensive income
(loss) and subsequently realized in earnings when the forecasted transaction
affects earnings.  The Company recorded a cumulative effect charge of $2.2
million, net of tax, in the income statement and $28 million, net of tax, in
accumulated other comprehensive loss to recognize at fair value the ineffective
and effective portions, respectively, of the losses on all derivative
instruments that are designated as cash flow hedging instruments, which
primarily consist of costless option collars and swaps on natural gas
production.

The Company recognized $5.0 million in earnings, representing the change in the
ineffective portion of the cash flow hedges for the six months ended June 30,
2001.  The Company realized a $26.0 million loss in earnings that was
reclassified from accumulated other comprehensive loss resulting from the
settlement of contracts when the natural gas was sold.  These gains and losses
are reported in Operating Revenues.  Other comprehensive income of $2.0 million
at June 30, 2001 is related to a cash flow exposure and will be realized in

K.    Energy Trading and Risk Management Activities

The Company engages in price risk management activities for both trading and
non-trading purposes.  On January 1, 2000, the Company adopted Emerging Issues
Task Force Issue No. 98-10, "Accounting for Energy Trading and Risk Management
Activities" (EITF 98-10) for its energy trading contracts.  EITF 98-10 requires
entities involved in energy trading activities to account for energy trading
contracts using mark-to-market accounting.  Prior to the adoption of EITF 98-10,
the Company accounted for its trading activities on the accrual method based on
settlement of physical positions.  The adoption of EITF 98-10 was accounted for
as a change in accounting principle and the cumulative effect at January 1, 2000
of $2.1 million, net of tax, was recognized.  Forwards, swaps, options, and
energy transportation and storage contracts utilized for trading activities are
reflected at fair value as assets and liabilities from price risk management
activities in the consolidated balance sheets.  The fair value of these assets
and liabilities are affected by the actual timing of settlements related to
these contracts and current period changes resulting primarily from newly
originated transactions and the impact of price movements.  Changes in fair
value are recognized in net revenues in the consolidated statement of income.
Market prices used to fair value these assets and liabilities reflect
management's best estimate considering various factors including closing
exchange and over-the-counter quotations, time value and volatility underlying
the commitments.  Market prices are adjusted for the potential impact of
liquidating the Company's position in an orderly manner over a reasonable period
of time under present market conditions.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

Some of the statements contained and incorporated in this Form 10-Q are forward-
looking statements within the meaning of the Private Securities Litigation
Reform Act of 1995.  The forward-looking statements relate to the anticipated
financial performance, management's plans and objectives for future operations,
business prospects, outcome of regulatory proceedings, market conditions and
other matters.  The Private Securities Litigation Reform Act of 1995 provides a
safe harbor for forward-looking statements in various circumstances.  The
following discussion is intended to identify important factors that could cause
future outcomes to differ materially from those set forth in the forward-looking
statements.

Forward-looking statements include the items identified in the preceding
paragraph, the information concerning possible or assumed future results of
operations and other statements contained or incorporated in this Form 10-Q
identified by words such as "anticipate," "estimate," "expect," "intend,"
"believe," "projection" or "goal."

You should not place undue reliance on the forward-looking statements.  They are
based on known and unknown risks, uncertainties and other factors that may cause
our actual results, performance or achievements to be materially different from
any future results, performance or achievements expressed or implied by the
forward-looking statements.  Those factors may affect our operations, markets,
products, services and prices.  In addition to any assumptions and other factors
referred to specifically in connection with the forward-looking statements,
factors that could cause our actual results to differ materially from those
contemplated in any forward-looking statement include, among others, the
following:

 .  the effects of weather and other natural phenomena on sales and prices;
 .  increased competition from other energy suppliers as well as alternative
   forms of energy;
 .  the capital intensive nature of the Company's business;
 .  further deregulation, or "unbundling" of the natural gas business;
   competitive changes in the natural gas gathering, transportation and storage
   business resulting from deregulation, or "unbundling," of the natural gas
   business;
 .  the profitability of assets or businesses acquired by the Company;
 .  risks of marketing, trading, and hedging activities as a result of changes in
   energy prices;
 .  economic climate and growth in the geographic areas in which the Company does
   business;
 .  the uncertainty of gas and oil reserve estimates;
 .  the timing and extent of changes in commodity prices for natural gas, natural
   gas liquids, electricity, and crude oil;
 .  the effects of changes in governmental policies and regulatory actions,
   including income taxes, environmental compliance, and authorized rates;
 .  the results of litigation related to the Company's now terminated proposed
   acquisition of Southwest Gas Corporation (Southwest) or to the termination of
   the Company's merger agreement with Southwest; and
 .  the other factors listed in the reports the Company has filed and may file
   with the Securities and Exchange Commission, which are incorporated by
   reference.

Other factors and assumptions not identified above were also involved in the
making of the forward-looking statements. The failure of those assumptions to be
realized, as well as other factors, may also cause actual results to differ
materially from those projected.

The Company's operating results decreased for the three months ended June 30,
2001 compared to the same period in 2000 primarily due to decreases in the
Gathering and Processing and Distribution segments.  Increased operating income
in the Marketing and Production segments largely offset these decreases.
Operating costs increased primarily due to increased personnel costs necessary
to support the expanded base of operations resulting from the acquisitions in
2000.  Other income, net includes income from equity investments that was
partially offset by ongoing litigation costs associated with the terminated
acquisition of Southwest.

The Company's operating results increased for the six-month period due to
acquisitions in 2000 , the impact of  volatility in gas prices and higher
average hedged prices on the Production segment.  Other income, net for the six
months ended June 30, 2001 includes approximately $6.2 million in income from
equity investments that was partially offset by a charge of $2.2 million related
to ongoing litigation costs associated with the terminated acquisition of
Southwest. Other income, net for  the six months ended June 30, 2000 includes a
$26.7 million gain on the sale of assets and income from equity investments
which were partially offset by a charge of $9.4 million of previously deferred
costs and ongoing litigation costs associated with the terminated acquisition of
Southwest, and other charges.

Higher gas prices and increased price volatility for the three and six months
ended June 30, 2001 compared to the same periods in 2000, resulted in increased
gas sales and cost of gas, although for the three-month period, a reduction in
volumes partially offset the increase in prices.  The decrease in sales volumes
was due to higher storage injections relative to the prior year as the Company
has focused on opportunistically securing storage volumes that are then hedged
at favorable winter/summer spreads.   For the six-month period, increased
volumes are primarily a result of the acquisition in 2000.   Marketing and
trading sales volumes averaged 2.2 Bcf/d and 2.8 Bcf/d for the three and six
months ended June 30, 2001 compared with 3.0 Bcf/d and 2.4 Bcf/d for the same
periods in 2000.

Operating costs decreased approximately $2.0 million for the three months ended
June 30, 2001 compared to the same period in 2000 due to a decrease in reserves
for doubtful accounts.  This decrease was partially offset by increased
personnel costs necessary to support the expanded base of marketing and trading
activities resulting from the acquisitions.

Natural gas liquids and condensate sales, gas sales, fee-based revenues and cost
of sales  increased for the three and six months ended June 30, 2001 compared to
the same periods in 2000, due primarily to stronger commodity prices.  The
impact of increases in natural gas liquids and condensate prices was partially
offset by decreased volumes resulting from the company and producers opting to
not extract liquids in periods when low or negative processing spreads made it
uneconomic to do so.  The increase in fee-based revenues from gathering,
compression, dehydration and processing was partially offset by a decrease due
to the expiration of a contract.  The contract was reinstated in June 2001 under
terms that were more favorable to the Company. Gross margin decreased for the
three-month period due to the effect of higher commodity prices, which increased
cost of sales.  Included in the cost of sales are higher fuel and shrinkage
costs, which resulted in reduced processing spreads on keep whole contracts.

For the six-month period,  increased volumes associated with the acquisitions in
2000 also contributed to the increases in revenues and cost of sales.

Operating costs increased for the three and six months ended June 30, 2001
compared to the same periods in 2000 primarily due to increased personnel costs
to support the expanded base of operations resulting from the acquisitions.  The
increase in assets from well connects and system enhancements also contributed
to the increase in depreciation, depletion, and amortization.

Other income, net in 2000 included the gain on the sale of the Company's 42.4
percent interest in the Indian Basin gas processing plant and gathering system
of $26.7 million.

Stronger market prices resulted in increases of 62 percent and 83 percent for
average NGL price realized and 101 percent and 148 percent for average gas sales
price realized for the three and six months, respectively.  Volumes of natural
gas gathered and processed decreased slightly for the three months ended June
30, 2001 compared to the same period in 2000 while volumes of gas and natural
gas liquids sold increased slightly for the same period.  The same volumes
increased for the six-month period due to the increased processing and
fractionation capacity acquired in the acquisitions.  These acquisitions
increased the Company's processing and fractionation capacity by 1.6 Bcf/d.  The
volume of natural gas liquids produced decreased for the three-month period
since prices made it uneconomical during certain times to extract liquids and
the Company opted not to process during those times.

Ethane sales as a percentage of total product sales decreased for the three and
six-month periods in 2001 compared to the same periods in 2000 due to ethane
rejection resulting from abnormally high natural gas prices relative to ethane.

Capital expenditures increased for the three and six months ended June 30, 2001
compared to the corresponding prior periods due to increased costs to sustain
operations due to having a higher asset base resulting from the acquisitions in
2000.

Total assets increased $244.2 million to $1.2 billion at June 30, 2001 from June
30, 2000 due primarily to a $166.8 million increase in accounts receivable as a
result of higher prices and a $57.1 million increase in net property, plant and
equipment.

Transportation and Storage

The transportation and storage segment represents the Company's intrastate
transmission pipelines and natural gas storage facilities.  The Company has four
storage facilities in Oklahoma, two in Kansas and three in Texas with a combined
working capacity of approximately 58 Bcf.  The Company's intrastate transmission
pipelines operate in Oklahoma, Kansas and Texas and are regulated by the
Oklahoma Corporation Commission (OCC), Kansas Corporation Commission (KCC), and
Texas Railroad Commission (TRC), respectively.

Transportation and gathering revenues increased for the three and six months
ended June 30, 2001 compared to the same period in 2000 primarily due to
increased volumes transported as a result of the acquisitions in 2000. A new
power plant load contributed to the increase in the three-month period.  Storage
revenues increased for the three and six-month periods primarily due to
increased storage rates and as a result of increased storage capacity from the
acquisitions.  Cost of fuel increased for the three and six-month periods due
to increased prices and increased volumes. Gross margin on gas sales relate to
merchant gas sales acquired in 2000 and incremental purchases and sales in 2001.
Most gas sales are on a fixed price basis while cost of gas reflects the higher
gas prices.

Operating costs increased for the three and six-month periods primarily as a
result of increased personnel costs to support the expanded base of operations
resulting from the acquisitions in 2000 and increased gathering costs.

Distribution

The Distribution segment provides natural gas distribution services in Oklahoma
and Kansas to residential, commercial and industrial customers.  The Company's
operations in Oklahoma are primarily conducted through Oklahoma Natural Gas
(ONG).   Operations in Kansas are conducted through Kansas Gas Service (KGS).
The Distribution segment serves about 80 percent of Oklahoma and about 72
percent of Kansas.  ONG is subject to regulatory oversight by the OCC, and  KGS
is subject to regulatory oversight by the KCC.

An Order received in May 2000 from the OCC, provided for a $20 million net
revenue reduction in rates which will be offset by an annual reduction in
depreciation expense of $11.4 million.  Pursuant to this Order, the Oklahoma
assets and customers of KGS were transferred to ONG.  This Order also adjusted
rates for the removal of the gathering and storage assets no longer included in
base rates and provided for the recovery of gas purchase, operations and
maintenance expenses and line losses through a rider rather than base rates.  An
Order from the KCC effective in July, 2000 reduced tariff rates.  The Order also
provided for the recovery of certain costs through a cost of gas rider rather
than through tariff rates, which reduces gross margin and operating costs by a
like amount.  See further discussion of matters with the OCC in the "Liquidity"
section, page 27.

Gas sales and cost of gas increased for the three and six months ended June 30,
2001 compared to the same periods in 2000 primarily due to increased gas costs.
Lower tariff rates and the impact of the temperature adjustment clause
negatively impacted gross margin for the three and six-month periods.  Weather
was colder than normal during the heating season in 2001, accordingly, margins
for customers whose rates are weather normalized were adjusted downward to
reflect the impact of normal weather.  However, during the heating season in
2000, KGS did not have weather normalized rates and did not receive the benefit
that weather normalized rates would have provided due to weather that was warmer
than normal.  For the six-month period, increased revenue from a line loss and
gathering rider and increased customer service revenue positively impacted gross
margin.

Increased bad debts due to the strong natural gas prices resulted in an increase
to operating costs of $7.5 million and $12.0 million for the three and six
months, respectively.

Residential and commercial gross margin per Mcf for the Oklahoma customers
decreased due to lower tariff rates effective in June, 2000.  Reduced volumes
for industrial customers in Oklahoma resulted in the customer charge being
spread over less volumes, which offset the effect of lower tariff rates and
resulted in a higher margin per Mcf.

Gross margin per Mcf for the Kansas residential and commercial customers
increased for the three-month period compared to the same period in 2000 despite
tariff reductions in July 2000.  The period of April through June, 2001 was
warmer than normal in Kansas resulting in increased revenues due to the weather
normalization process approved by the KCC effective December 1, 2000.  This
process spread higher revenues over the actual delivered volumes contributing to
a higher margin per Mcf.  Additionally, the WeatherProof rate program in Kansas,
which provides for a levelized bill each month, contributed to higher margins
per Mcf in a period in which weather was warmer than normal.  Industrial margins
in Kansas are lower due to the tariff reductions.

Total assets increased $211.3 million at June 30, 2001 compared to the same date
in 2000 due primarily to a $75.5 million increase in accounts receivable and an
$80.3 million increase in unrecovered purchased gas costs resulting from the
increase in natural gas prices. Customers per employee for the three and six-
month periods increased  as a result of the decline in numbers of employees due
to normal attrition while the customer base continues to grow.

Total residential and commercial volumes decreased for the three months due to
warmer weather in the second quarter of 2001 compared to the same period in
2000.  For the six months, the decrease during the second quarter was generally
offset by the effect of colder than normal weather during the first quarter of
2001 compared to warmer than normal weather during the first quarter of 2000.
Wholesale, PCL and ECT volumes decreased due to certain customers curtailing
manufacturing due to the high natural gas prices.   These decreases in volumes
were partially offset by more customers qualifying for PCL and ECT rates due to
a reduction in the minimum capacity requirements pursuant to regulatory orders.

Certain costs to be recovered through the rate making process have been recorded
as regulatory assets in accordance with Statement of Financial Accounting
Standards No. 71, "Accounting for the Effects of Certain Types of Regulation".
As services continue to unbundle, certain of these assets may no longer meet the
criteria of a regulatory asset, and accordingly, a write-off of regulatory
assets and stranded costs may be required.  The Company's most  recent Orders
did not change the recoverability of regulatory assets.  The Company has been
authorized to recover transition costs incurred due to natural gas industry
restructuring.  An initial amount of $1.8 million has been authorized.  This
recovery level will be updated annually.  Accordingly, the Company does not
anticipate that write-off of costs, if any, will be material.

Production

The Production segment owns and develops natural gas and oil reserves primarily
in Oklahoma and Kansas. The Company has proved reserves of 250.4 Bcf of natural
gas and 4.3 million barrels of oil.

For the three and six months ended June 30, 2001 compared to the same periods in
2000, natural gas sales and oil sales increased due to substantially higher
realized prices with the increase in prices partially offset by the reduction in
natural gas sales volumes due to normal production declines.  For the same
periods, operating costs increased primarily due to increased production taxes
resulting from the higher prices.  Production taxes are calculated based on
wellhead price rather than realized price.

Power

The Company created the Power segment on January 1, 2001, to include the
operating results of the peak electric generating plant constructed by the
Company.  The Company's strategy is to capture the spark spread primarily during
peak demand periods.  Prior to January 1, 2001, capital expenditures for the
construction of the plant had been included in the Marketing and Trading
segment.  These capital expenditures have been reclassified and included in the
Power segment for the periods shown in this report.  The plant was capable of
operation in May 2001.  For the three and six months ended June 30, 2001,
capital expenditures relating to the construction of the electric generating
plant were $11.6 million and $40.0 million, respectively, compared to $10.2
million and $19.6 for the same periods in 2000, respectively.

B.  Financial Flexibility and Liquidity

Operating Cash Flows

Operating cash flows for the six months ended June 30, 2001, as compared to the
same period one year ago, were $254.3 million compared to $198.0 million.  Cash
flow from operating activities was positively impacted in the current year due
to the collection of increased accounts receivables and reduced deposits, which
were partially offset by increased cash used for payment of accounts payable and
gas in storage and reduced recovery of unrecovered  purchased gas costs.
Receivables are typically higher during the heating season, however they were
higher than normal at December 31, 2000 due to the higher gas prices and the
integration of the businesses acquired in 2000.  Consistent with receivables,
accounts payable are typically higher during the heating season resulting in
payments being made during the first six months of the year.  A reduction in
margin deposits required on futures and options contracts for the Marketing
and Trading segment is due to the drop in gas prices at June 30, 2001 compared
to December 31, 2000. The increase in gas in storage during the six months ended
June 30, 2001 compared to the decrease in gas in storage for the prior six-month
period is a result of increased volumes in storage as well as higher gas prices
as the Company focused on opportunistically securing volumes that are then
hedged at favorable winter/summer spreads. For the six months ended June 30,
2000, the increase in the unrecovered purchased gas costs is due to higher gas
prices and the OCC's extending the recovery of the costs to mitigate the impact
on customers. See "Liquidity", page 27. Although receivables and payables would
normally have been expected to decrease from December 31, 1999 to June 30, 2000
due to seasonality as discussed above, receivables and payables increased during
this period due to the acquisitions.

Investing Cash Flows

Cash paid for capital expenditures and acquisitions for the six months ended
June 30, 2001, was $174.0 million and $15.3 million, respectively.  Capital
expenditures include $40.0 million for construction of an electric generating
plant. For the same period one year ago, capital expenditures were $125.4
million and acquisitions were $460.5 million.  Capital expenditures for the six
months ended June 30, 2000 relating to the construction of an electric
generating plant were $19.6 million. The increase in capital expenditures for
the six months ended June 30, 2001 compared to the same period in 2000 is
primarily attributable to increased cost of sustaining a higher asset base due
to the acquisitions and the costs related to construction of the electric
generating plant.  Acquisitions for 2001 included $14.5 million of purchase
price adjustments related to the Kinder Morgan acquisition.

Financing Cash Flows

The Company's capitalization structure is 42 percent equity and 58 percent debt
at June 30, 2001, compared to 48 percent equity and 52 percent debt at December
31, 2000. At June 30, 2001, $1.74 billion of long-term debt was outstanding.  As
of that date, the Company could have issued $739 million of additional long-term
debt under the most restrictive provisions contained in its various borrowing
agreements.  The increase in debt, incurred to finance acquisitions, resulted in
the increase in interest costs for the six months ended June 30, 2001 compared
to the same period in 2000.

                                       26


In April 2001, the Company issued $400 million of ten year, 7.125 percent, fixed
rate notes to pay off short-term debt.

On July 18, 2001, the Company filed a "shelf" registration statement on Form S-3
pursuant to which the Company may offer debt securities and shares of the
Company's Common Stock in one or more offerings with a total initial offering
price of up to $500 million.

The Board of Directors has authorized up to $1.2 billion of short term financing
to be obtained as necessary for the operation of the corporation and its
subsidiaries.  The Company has an $850 million revolving credit facility with a
maturity date of June 27, 2002.  This credit facility is primarily used to
support the commercial paper program. At June 30, 2001, $414.4 million of
commercial paper was outstanding.

Although cash provided by operating activities continues as the primary source
for meeting day-to-day cash requirements, due to seasonal fluctuations,
acquisitions, and additional capital requirements, the Company accesses funds
through commercial paper, and short-term credit agreements and, if necessary,
through long-term borrowing.

Liquidity

Competition continues to increase in all segments of the Company's business.
The loss of major customers without recoupment of those revenues and lower
spreads in the Gathering and Processing segment are events that could have a
material adverse effect on the Company's financial condition.  However,
strategies such as aggressive negotiations to reduce keep whole contract
exposure, weather normalization in Kansas and Oklahoma, and increased use of
storage in the day trading market are expected to reduce other risks to the
Company.  Additionally, rates in the Distribution segment are structured to
reduce the Company's risk in serving its large customers.

The OCC staff recommended to the OCC that ONG's unrecovered purchased gas cost
(UPGC) clause be suspended because ONG allegedly failed to "act prudently" in
acquiring its gas supply for the 2000/2001 heating season resulting in an
alleged $72.1 million in excess charges to ratepayers through March 31, 2001.
The hearing on the merits of the  OCC's case was conducted on June 25-27, 2001,
after which the OCC took the matter under advisement.  ONG and the OCC submitted
proposed orders on July 13, 2001.  If the OCC staff is successful, the Company
would not be allowed to recover approximately $72.1 million in UPGC which could
have a material adverse effect on the Company's operations, cash flow, and
financial position.  The Company believes that the OCC staff's recommendation is
without merit and is defending itself vigorously against this recommendation.

The Company believes that internally generated funds and access to financial
markets will be sufficient to meet its normal debt services, dividend
requirements, and capital expenditures.

C.      Impact of Recently Issued Accounting Pronouncements

In July 2001, the FASB issued Statement of Financial Accounting Standards No.
141, "Business Combinations" (Statement 141), Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets" (Statement 142), and
Statement of Financial Accounting Standards No. 143, "Accounting for Asset
Retirement Obligations" (Statement 143).  Statement 141 requires that the
purchase method of accounting be used for all business combinations initiated
after June 30, 2001.  Statement 142 will require that goodwill and intangible
assets with indefinite useful lives no longer be amortized, but instead tested
for impairment at least annually in accordance with the provisions of Statement
142.  The Company is required to adopt the provisions of Statement 141
immediately, and Statement 142 effective January 1, 2002.  Goodwill acquired in
business combinations completed before July 1, 2001 will continue to be
amortized prior to the adoption of Statement 142.   Statement 143 requires
entities to record the fair value of a liability for an asset retirement
obligation in the period in which it is incurred and a corresponding increase in
the carrying amount of the related long-lived asset.  Statement 143 is effective
for fiscal years beginning after June 15, 2002. The Company is currently
assessing the impact of Statement 143 on its financial condition and results of
operations.

                                       27


In connection with the Company's adoption of Statement 142, the Company will be
required to perform an assessment of whether there is an indication that
goodwill, including equity-method goodwill, is impaired as of the date of
adoption.  Any transitional impairment loss will be recognized as the cumulative
effect of a change in accounting principle in the Company's statement of
earnings.

As of June 30, 2001, the Company has unamortized goodwill in the amount of
$149.1 million, which will be subject  to the transition provisions of Statement
142.  Amortization expense related to goodwill was $3.2 million and $2.2 million
for the year ended December 31, 2000 and the six months ended June 30, 2001,
respectively.  Because of the extensive effort needed to comply with adopting
Statements 141 and 142, no estimate is available of the impact of adopting these
Statements.  The Company will discontinue amortization of goodwill effective
January 1, 2002, with the adoption of Statement 142.

D.  Other

Southwest Gas Corporation

In connection with the now terminated proposed acquisition of Southwest Gas
Corporation (Southwest), the Company is party to various lawsuits.  These
lawsuits originally contained allegations that include, but are not limited to,
federal and state Racketeer Influenced and Corrupt Organizations (RICO) Act
violations and improper interference in a contractual or other business
relationship between Southwest and Southern Union Corporation (Southern Union).
Southern Union's complaint originally asked for $750 million damages to be
trebled for alleged RICO violations, compensatory damages of not less than $750
million, punitive damages, and rescission of the Confidentiality and Standstill
Agreement.  On June 21, 2001, the Court dismissed with prejudice Southern
Union's claim for fraudulent inducement against the Company, Gene Dubay and John
Gaberino.  The Court did not dismiss the claim by Southern Union against
Southwest and Michael Maffie. The Court also dismissed with prejudice Southern
Union's claims for tortious interference with a contractual relationship against
the Company.  This claim remains pending against only Gene Dubay, John Gaberino,
James Irvin and Jack Rose.  The Court denied the motion to dismiss Southern
Union's claim for tortious interference with a prospective relationship against
the Company, Gene Dubay and John Gaberino.  On June 29, 2001, the Company filed
a motion for summary judgment in its favor on the sole remaining claim asserted
against it by Southern Union.  Various other motions for summary judgment were
filed by other parties, all of which are scheduled for hearing on August 24,
2001.

The Company, as third party beneficiary, has filed a lawsuit against Southern
Union for, among other things, breach of a confidentiality agreement with
Southern Union and Southwest and tortious interference with the Southwest merger
agreement.  The Company filed suit against Southwest seeking a declaratory
judgment determining that it had properly terminated the merger agreement.  In
response to this suit, Southwest brought a suit against the Company and Southern
Union alleging, among other things, fraud and breach of contract.  Southwest is
seeking damages in excess of $75,000.

Most of the lawsuits discussed above have been consolidated into one case.  The
court has entered an order setting the cases for jury trial on November 12,
2001.

Two substantially identical derivative actions were filed by shareholders
against the members of the Board of Directors of the Company for alleged
violation of their fiduciary duties to the Company by causing or allowing the
Company to engage in certain fraudulent and improper schemes designed to
"sabotage" Southern Union Company's competitive bid to acquire Southwest and
secure regulatory approval for the Company's own planned merger with Southwest.
Such conduct allegedly caused the Company to be sued by both Southwest and
Southern Union, which exposed the company to millions of dollars in liabilities.
The allegations are used as a basis for causes of action for intentional breach
of fiduciary duty, derivative claim for negligent breach of fiduciary duty,
class and derivative claims for constructive fraud, and derivative claims for
gross mismanagement.  Each plaintiff seeks a declaration that the lawsuit is
properly maintained as a derivative action, the defendants, and each of them,
have breached their fiduciary duties to the Company, an injunction permanently
enjoining defendants from further abuse of control and committing of gross
mismanagement and constructive fraud, and asks for an award of compensatory and
punitive damages and costs, disbursements and reasonable attorney fees. A Joint
Motion for Consolidation of both derivative actions was filed on

                                       28


June 6, 2000, and Pretrial No. 1 was entered on that date consolidating the
actions and establishing a schedule for response to a consolidated petition. On
July 21, 2000, the plaintiffs filed their Consolidated petition. Stephen J.
Jatras and J.M. Graves have been eliminated as defendants in the Consolidated
petition, but Eugene Dubay was added as a new defendant. The plaintiffs also
dropped their class and derivative claim for constructive fraud, but added a new
derivative claim for waste of corporate assets. On September 19, 2000, the
Company, the Independent Directors (Anderson, Bell, Cummings, Ford, Fricke,
Lake, Mackie, Newsom, Parker, Scott and Young), David Kyle, and Gene Dubay filed
Motions to Dismiss the action for failure of the plaintiffs to make a pre-suit
demand on the Company's Board of Directors. In addition, the Independent
Directors, David Kyle, and Gene Dubay filed Motions to Dismiss the Plaintiffs'
Consolidated Petition for failure to state a claim. On January 3, 2001, the
Court dismissed the action without prejudice as to its claims against Larry
Brummett. On February 26, 2001, the action was stayed until one of the parties
notifies the Court that a dissolution of the stay is requested.

If any of the plaintiffs should be successful in any of their claims against the
Company and substantial damages are awarded, it could have a material adverse
effect on the Company's operations, cash flow, and financial position.  At the
present time, the Company is unable to estimate the possible loss, if any,
associated with these matters.  The Company is defending itself vigorously
against all claims asserted by Southern Union and Southwest and all other
matters relating to the now terminated proposed acquisition with Southwest.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Risk Management - The Company, substantially through its non-utility segments,
is exposed to market risk in the normal course of its business operations and to
the impact of market fluctuations in the price of natural gas, NGLs and crude
oil.  Market risk refers to the risk of loss in cash flows and future earnings
arising from adverse changes in commodity energy prices.  The Company's primary
exposure arises from fixed price purchase or sale agreements which extend for
periods of up to 48 months, gas in storage inventories utilized by the gas
marketing and trading operation, and anticipated sales of natural gas and oil
production.  To a lesser extent, the Company is exposed to risk of changing
prices or the cost of intervening transportation resulting from purchasing gas
at one location and selling it at another (hereinafter referred to as basis
risk).  To minimize the risk from market fluctuations in the price of natural
gas, NGLs and crude oil, the Company uses commodity derivative instruments such
as futures contracts, swaps and options to manage market risk of existing or
anticipated purchase and sale agreements, existing physical gas in storage, and
basis risk.  The Company adheres to policies and procedures that limit its
exposure to market risk from open positions and monitors its exposure to market
risk.

Interest Rate Risk - The Company is subject to the risk of fluctuation in
interest rates in the normal course of business.  The Company manages interest
rate risk through the use of fixed rate debt, floating rate debt and at times
interest rate swaps.  The Company had no interest rate swaps at June 30, 2001.
However, in July 2001, the Company entered into an interest rate swap on a total
of $400 million in long term debt.  The rate resets periodically based on the
three-month LIBOR or the six-month LIBOR at the reset date.  Excluding the
effect of these new swap agreements, a hypothetical 10 percent change in
interest rates would result in an annual $1.8 million change in interest costs
related to short-term and floating rate debt based on principal balances
outstanding at June 30, 2001.

Value-at-Risk Disclosure of Market Risk - ONEOK measures entity-wide market risk
in its trading, price risk management, and its non-trading portfolios using
value-at-risk.  The quantification of market risk using value-at-risk provides a
consistent measure of risk across diverse energy markets and products with
different risk factors in order to set overall risk tolerance, to determine risk
targets and set position limits.  The use of this methodology requires a number
of key assumptions including the selection of a confidence level and the holding
period to liquidation.  ONEOK relies on value-at-risk to determine the potential
reduction in the trading and price risk management portfolio values arising from
changes in market conditions over a defined period.

ONEOK's value-at-risk exposure represents an estimate of potential losses that
would be recognized for its trading and price risk management portfolio of
derivative financial instruments, physical contracts and gas in storage assuming
hypothetical movements in commodity market assumptions with no change in
positions and are not necessarily indicative of actual results that may occur.
Value-at-risk does not represent the maximum possible loss nor any expected loss
that may occur because actual future gains and losses will differ from those
estimated based on actual fluctuations in commodity prices, operating exposures
and timing thereof, and the changes in the Company's trading and price risk
management portfolio of derivative financial instruments and physical contracts.

At June 30, 2001, the Company's estimated potential one-day favorable or
unfavorable impact on future earnings, as measured by the value-at-risk, using a
95 percent confidence level and diversified correlation assuming one day to
liquidate positions was $2.7 million for its non-trading portfolio and
immaterial for its trading portfolio.

this case be consolidated with Case No. CIV-99-1294-PHX-ROS brought by Southern
Union in the United States District Court for the District of Arizona.  On June
29, 2001, Southern Union filed a motion for summary judgment in its favor on the
claims asserted against it by the Company in this action.  A hearing on the
motion is scheduled for August 24, 2001.

Southern Union Company v. Southwest Gas Corporation, et al., No. CIV-99-1294-
- ----------------------------------------------------------
PHX-ROS, United States District Court for the District of Arizona.  On May 21,
2001, the Court denied Southern Union's motion to reconsider its ruling
dismissing the federal RICO claim against the Company or to enter a judgment on
the ruling.  The Court also applied its ruling to dismiss the state RICO claim
asserted by Southern Union against the Company.  The Court's rulings on the RICO
claims were made applicable to all defendants.  On June 1, 2001, the Court
ordered that Case Nos. 99-CV-0345-H(M) and 00-CV-063-H(E) brought by the Company
against Southern Union and Southwest be consolidated with this action.  On June
21, 2001, the Court ruled on the defendants' motions to dismiss the claims
asserted by Southern Union.  The Court dismissed with prejudice Southern Union's
claims for fraudulent inducement against the Company and Messrs. Dubay and
Gaberino.  This claim by Southern Union remains pending against Southwest and
Mr. Maffie.  The Court also dismissed with prejudice Southern Union's claim for
tortious interference with a contractual relationship against the Company.  This
claim by Southern Union remains pending against only Messrs. Dubay, Gaberino,
Irvin, and Rose.  The Court denied the motions to dismiss Southern Union's claim
for tortious interference with a prospective business relationship against the
Company and Messrs. Dubay and Gaberino.  The Court's June 21 order also
determined several other pending motions and related issues which will affect
the conduct of the trial.  On June 29, 2001, the Company filed a motion for

Quinque Operating Company, et al. v. Gas Pipelines, et al., 26th Judicial
- ---------------------------------------------------------
District, Stevens County, Kansas, Civil Department, Case No. 99C30.  On June 8,
2001, a Second Amended Petition was filed as a purported class action against
225 defendants, including ONEOK, Inc., one of its divisions and five of its
subsidiaries.  The Second Amended Petition was purportedly filed on behalf of
all producers and royalty owners who have lost money as the result of
mismeasurement of gas since 1974 from any of the 225 defendants.  The Second
Amended Petition alleges that each of the 225 defendants engaged in one or more
specific "mismeasurement techniques" and conspired with one another to
undermeasure the gas sold by the alleged class members.  One of the named
subsidiaries of the Company, ONEOK WesTex Transmission, Inc., is a former
subsidiary of Kinder Morgan and was named as a defendant in the First Amended
Petition.  Kinder Morgan has agreed to assume the defense of ONEOK WesTex while
reserving its rights and denying that it has any obligation to indemnify the
Company against any loss suffered by ONEOK WesTex as result of this litigation.
The ONEOK defendants, other than

                                       31


ONEOK WesTex, were not originally joined in this lawsuit until the Second
Amended Petition was filed by the plaintiffs. Discovery, except on class
certification and personal jurisdictional grounds, has been stayed. The Company
intends to vigorously defend all aspects of these claims, including procedural
and class action issues and will seek indemnification from Kinder Morgan on any
claims dealing with ONEOK WesTex. The case is in the early procedural stages and
the Company is not yet in a position to assess the materiality of this
litigation.
