                  SOUTHWESTERN ENERGY COMPANY AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               SEPTEMBER 30, 2001

1.       BASIS OF PRESENTATION

         The financial statements included herein are unaudited;  however,  such
         financial  statements  reflect all  adjustments  (consisting  solely of
         normal recurring  adjustments) which are, in the opinion of management,
         necessary  for a fair  presentation  of the  results  for  the  interim
         periods.  The Company's  accounting policies are summarized in the 2000
         Annual  Report on Form 10-K,  Item 8, Notes to  Consolidated  Financial
         Statements.

2.       OIL AND GAS PROPERTIES

         The  Company  utilizes  the full cost  method of  accounting  for costs
         related to its oil and natural gas properties.  Under this method,  all
         such costs (productive and nonproductive) are capitalized and amortized
         on an aggregate basis over the estimated lives of the properties  using
         the units-of-production  method. These capitalized costs are subject to
         a  ceiling  test,  however,  which  limits  such  pooled  costs  to the
         aggregate of the present value of future net revenues  attributable  to
         proved gas and oil reserves  discounted at 10 percent plus the lower of
         cost or market value of unproved properties. At September 30, 2001, the
         Company's  unamortized  costs of oil and gas  properties  exceeded this
         ceiling amount by $54.8 million due to low gas prices in effect on that
         date.  The  market  price  for  natural  gas at Henry  Hub was $1.86 on
         September  30, 2001.  However,  due to the  subsequent  recovery in the
         market  prices for natural gas the Company was not required to record a
         write-down  of its oil and gas  properties.  The  Company's  full  cost
         ceiling is evaluated at the end of each  quarter.  A decline in gas and
         oil  prices  from  current  levels,  or other  factors,  without  other
         mitigating   circumstances,   could  cause  a  future   write-down   of
         capitalized costs and a non-cash charge against future earnings.

3.       EARNINGS PER SHARE

         Basic  earnings  per common share is computed by dividing net income by
         the weighted  average number of common shares  outstanding  during each
         year. The diluted  earnings per share  calculation adds to the weighted
         average number of common shares outstanding the incremental shares that
         would have been  outstanding  assuming the  exercise of dilutive  stock
         options.  The Company had  options for 997,700  shares of common  stock
         with a weighted average exercise price of $13.90 per share at September
         30, 2001,  and options for  2,033,665  shares with an average  exercise
         price of $10.53 per share at September 30,

                                     - 8 -


         2000,  that were not  included  in the  calculation  of diluted  shares
         because they would have had an antidilutive effect.

4.       UNUSUAL ITEMS

         During the first nine  months of 2000,  the  Company  recorded  unusual
         charges  totaling  $111.3 million related to the adverse Hales judgment
         and other litigation.

5.       DIVIDEND PAYABLE

         As a result of the financial impact of the Hales judgment in the second
         quarter of 2000,  the Company  has  indefinitely  suspended  payment of
         quarterly dividends on its common stock.

6.       LONG-TERM DEBT

         In July 2001,  the Company  arranged a new unsecured  revolving  credit
         facility  with a group of  banks to  replace  its  existing  short-term
         credit  facility that was put in place in July 2000.  The new revolving
         credit  facility has a capacity of $160 million and a three-year  term.
         The  interest  rate on the new  facility is 137.5 basis points over the
         current  London  Interbank  Offered  Rate  (LIBOR),  and  was  4.9%  at
         September 30, 2001. The new credit  facility  contains  covenants which
         impose certain restrictions on the Company. Under the credit agreement,
         the  Company  may not  issue  total  debt in excess of 75% of its total
         capital, must maintain a certain level of shareholders' equity, and the
         Company  must  maintain a ratio of  earnings  before  interest,  taxes,
         depreciation  and  amortization  (EBITDA) to fixed  charges of at least
         3.75 or higher through March 30, 2002.  These covenants change over the
         term of the credit facility and generally become more  restrictive.  At
         September  30, 2001,  the  Company's  revolving  credit  facility had a
         balance of $131.3  million and was  classified as long-term debt in the
         Company's  balance sheet. The Company has also entered into an interest
         rate swap for calendar year 2002 that allows the Company to pay a fixed
         interest rate of 5.7% on $50 million of its outstanding revolving debt.

7.       DERIVATIVE AND HEDGING ACTIVITIES

         Statement of Financial  Accounting  Standards No. 133,  "Accounting for
         Derivative  Instruments and Hedging  Activities" as amended by SFAS No.
         137 and SFAS No.  138,  was  adopted by the Company on January 1, 2001.
         SFAS No. 133 requires that each derivative be recognized in the balance
         sheet as  either  an asset or  liability  measured  at its fair  value.
         Special  accounting for qualifying  hedges allows a derivative's  gains
         and losses

                                     - 9 -


         to offset  related  results on the hedged item in the income statement.

         Upon adoption of SFAS No. 133 on January 1, 2001, the Company  recorded
         a transition  obligation of $60.6  million  related to cash flow hedges
         that are intended to reduce the volatility in commodity  prices for the
         Company's forecasted oil and gas production. At September 30, 2001, the
         Company  recorded  assets of $9.8 million  related to its commodity and
         interest  rate cash flow hedges.  Additionally,  at September 30, 2001,
         the  Company   recorded   net  of  tax   cumulative   income  to  other
         comprehensive  income  (equity  section of the  balance  sheet) of $6.0
         million.  The amount  recorded  in other  comprehensive  income will be
         taken to the income statement as the physical transactions being hedged
         occur. Additional volatility in earnings and other comprehensive income
         may occur in the future as a result of the adoption of SFAS No. 133.

8.       SEGMENT INFORMATION

         The Company  applies SFAS No. 131,  "Disclosures  about  Segments of an
         Enterprise and Related  Information." The Company's reportable business
         segments have been  identified  based on the differences in products or
         services provided.  Revenues for the exploration and production segment
         are derived from the  production and sale of natural gas and crude oil.
         Revenues for the gas distribution segment arise from the transportation
         and sale of natural  gas at retail.  The  marketing  segment  generates
         revenue  through the marketing of both Company and third party produced
         gas volumes.

         Summarized financial  information for the Company's reportable segments
         are shown in the following  table.  The "Other"  column  includes items
         related  to   non-reportable   segments   (real   estate  and  pipeline
         operations) and corporate items.

10.      MINORITY INTEREST IN PARTNERSHIP

         In the second quarter of 2001, the Company formed a limited partnership
         with an investor to drill and complete the first 14  development  wells
         in the Company's Overton Field located in Smith County,  Texas. Because
         Southwestern is the sole general partner and controls the  partnership,
         the operating and financial results are consolidated with the Company's
         exploration  and  production  results and the  investor's  share of the
         partnership  activity is reported  as a minority  interest  item in the
         financial  statements.  The Company will  contribute 50% of the capital
         required  to drill  the  first 14  wells.  Revenues  and  expenses  are
         allocated 65% to the Company prior to payout of the initial  investment
         and 85% to the Company thereafter.

11.      CONTINGENCIES AND COMMITMENTS

         The  Company  and the other  general  partner of NOARK  have  severally
         guaranteed  the principal and interest  payments on NOARK's 7.15% Notes
         due 2018.  At September  30, 2001 and December 31, 2000,  the principal
         outstanding  for  these  Notes  was $74.0  million  and $75.0  million,
         respectively.  The Company's share of the several guarantee is 60%. The
         Notes  were  issued  in June  1998 and  require  semi-annual  principal
         payments of $1.0
                                     - 12 -


         million.  Under the several guarantee,  the Company is required to fund
         its share of NOARK's debt service  which is not funded by operations of
         the pipeline. As a result of the integration of NOARK Pipeline with the
         Ozark Gas Transmission System,  management of the Company believes that
         it will  realize its  investment  in NOARK over the life of the system.
         Therefore,  no provision for any loss has been made in the accompanying
         financial  statements.  Additionally,  the Company's  gas  distribution
         subsidiary has transportation contracts for firm capacity of 66.9 MMcfd
         on NOARK's integrated  pipeline system.  These contracts expire in 2002
         and 2003, and are renewable year-to-year thereafter until terminated by
         180 days' notice.

         The  Company is also  subject to laws and  regulations  relating to the
         protection  of the  environment.  The  Company's  policy  is to  accrue
         environmental  and cleanup related costs of a noncapital nature when it
         is both probable that a liability has been incurred and when the amount
         can be reasonably estimated. Management believes any future remediation
         or other  compliance  related costs will not have a material  effect on
         the  financial  position  or  reported  results  of  operations  of the
         Company.

         The Company is subject to other  litigation and claims that have arisen
         in the ordinary course of business.  The Company accrues for such items
         when a  liability  is both  probable  and the amount can be  reasonably
         estimated. In the opinion of management, the results of such litigation
         and claims will not have a material effect on the results of operations
         or the financial position of the Company.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The  following  updates  information  as to the  Company's  financial  condition
provided in the Company's  Form 10-K for the year ended  December 31, 2000,  and
analyzes  the  changes in the results of  operations  between the three and nine
month periods ended September 30, 2001, and the comparable periods of 2000.

RESULTS OF OPERATIONS

Net income for the three months ended  September 30, 2001 was $5.0  million,  or
$.20 per share,  compared to a net loss of $.8  million,  or $.03 per share,  in
2000.  The  increase  in net  income  was  due  to  improved  operating  results
experienced by the exploration and production  segment.  This segment  benefited
from both increased production and higher commodity prices.

Net income for the nine months ended  September 30, 2001, was $27.9 million,  or
$1.11 of basic  earnings per share ($1.09 per share on a fully  diluted  basis),
compared to a net loss for the nine months ended  September  30, 2000,  of $55.8
million,  or $2.23 per share.  The  Company's  results for the nine months ended
September 30, 2000, included an unusual charge of $109.3 million for the adverse
judgment  in  the  Hales  royalty   lawsuit   ($66.7  million   after-tax),   an
extraordinary loss on the early retirement of debt, a $3.2 million gain from the
sale of the Company's Missouri utility properties,  and a $2.0 million charge in
the third  quarter  related to other  litigation.  Excluding  these  unusual and
extraordinary  items,  Southwestern  would  have  reported  net  income of $11.1
million, or $.44 per share, for the first nine months of 2000.

                           Exploration and Production

Overview
The Company's  exploration and production  segment's revenue,  profitability and
future rate of growth are  substantially  dependent upon  prevailing  prices for
natural  gas and oil,  which are  dependent  upon  numerous  factors  beyond its
control, such as economic, political and regulatory developments and competition
from other sources of energy.  The energy  markets have  historically  been very
volatile,  and there can be no  assurance  that oil and gas  prices  will not be
subject to wide fluctuations in the future.

         for  litigation  and a loss of $109.3  million in the second quarter of
         2000 for the Hales judgment.  Excluding these items,  operating  income
         for the exploration and production segment would have been $9.2 million
         and $25.5 million for the three and nine month periods ended  September
         30, 2000, respectively.

(2)      Includes  $2.0  million,  or  $.07  per  Mcfe for the nine months ended
         September 30, 2001, for settled litigation.

Revenues and Operating Income
Revenues for the  exploration  and production  segment were up 36% for the three
months  ended  September  30,  2001 and up 55% for the nine month  period  ended
September 30, 2001, compared to the same periods in 2000. The increases were due
to both higher gas and oil prices and increased gas and oil production.

Operating  income,  excluding  unusual items, for the exploration and production
segment was up $6.7 million for the three months ended  September 30, 2001,  and
up $30.7 million for the first nine months of 2001, both as compared to the same
periods in 2000.  The  improvements  in operating  income were due to the higher
segment  revenues,  partially  offset by increased  depreciation,  depletion and
amortization expense.

Production
Gas and oil  production  during the third quarter of 2001 was 10.5 billion cubic
feet (Bcf)  equivalent,  up 17% from 9.0 Bcf  equivalent  for the same period in
2000. The increase in production primarily resulted from new wells added in 2000
and 2001 in the  Company's  Arkoma  Basin and Gulf Coast  operating  areas.  Gas
production  was 9.4 Bcf for the third  quarter of 2001,  compared to 7.9 Bcf for
the same period in 2000.  For the nine months ended  September 30, 2001, gas and
oil production was 29.3 Bcf equivalent,  up 10% from 26.6 Bcf equivalent for the
same

                                     - 15 -


period in 2000.  Gas  production  was 26.1 Bcf for the first nine months of 2001
compared to 23.6 in 2000.

The Company's sales to its gas distribution systems were 3.7 Bcf during the nine
months  ended  September  30,  2001,  compared to 5.8 Bcf for the same period in
2000. Gas supply for the Company's gas distribution  systems is provided using a
competitive bidding process.  Future sales to the gas distribution  systems will
be dependent upon the Company's  success in obtaining gas supply  contracts with
the utility systems.

During the third quarter of 2001,  the Company was  successful in obtaining four
out of six bid  packages to supply the gas  distribution  systems with base load
and  swing-service  gas supplies  beginning in the fourth  quarter of 2001.  The
Company was  unsuccessful  in bidding on a no-notice gas supply  package that it
previously  held.  This no-notice gas supply package  extends  through the first
quarter of 2002. In the future, the Company will continue to bid to obtain these
gas supply packages, although there is no assurance that  it will be successful.
If successful, the Company cannot predict the  amount of  premium that  would be
associated with the new contracts.

Commodity Prices
The Company realized an average price of $3.37 per thousand cubic feet (Mcf) for
its natural gas  production  for the three months ended  September  30, 2001, up
from $2.87 per Mcf for the same  period of 2000.  For the first  nine  months of
2001, the Company  realized an average gas price of $3.97 per Mcf, up from $2.71
for the same period of 2000.  The Company  hedged 20.4 Bcf of gas  production in
the first nine months of 2001 primarily through zero-cost collars, which had the
effect of increasing  the average gas price by $.57 per Mcf in the third quarter
of 2001 and  reducing  the  average  gas price by $.78 per Mcf in the first nine
months of 2001. On a comparative  basis,  the average  realized price during the
third  quarter of 2000 was  reduced by $1.36 per Mcf and was reduced by $.73 per
Mcf in the first  nine  months of 2000,  due to the  effect of  commodity  price
hedges.

For the remainder of 2001, the Company has 6.2 Bcf of gas production hedged with
collars  having an  average  NYMEX  floor  price of $4.06 per Mcf and an average
NYMEX  ceiling  price  of  $4.95  per Mcf.  The  Company  also has .4 Bcf of gas
production for the remainder of 2001 hedged with fixed-price swaps at an average
NYMEX price of $3.19 per Mcf.  For 2002,  the Company has  fixed-price  swaps on
13.0 Bcf at an average NYMEX price of $2.88 and a collar on 6.0 Bcf with a floor
price of  $4.00  and a  ceiling  price of  $4.72.  For  2003,  the  Company  has
fixed-price  swaps on 9.2 Bcf at an average  NYMEX  price of $3.18.  See Part I,
Item 3 of this Form 10-Q for  additional  information  regarding  the  Company's
commodity price risk hedging activities.

The  Company  received  an  average  price  of  $23.75  per  barrel  for its oil
production  during the three months ended September 30, 2001, up from $21.56 per
barrel for the same period of 2000.

                                     - 16 -


For the nine months ended  September 30, 2001,  the Company  received an average
price of $24.67 per barrel for its oil production, up from $22.36 per barrel for
the same period of 2000.  For the remainder of 2001, the Company has a collar on
75,000  barrels  with an  average  floor of $27.40  per  barrel,  and an average
ceiling of $29.95 per barrel,  and a hedge on 24,000 barrels at an average NYMEX
price of $17.49 per barrel.

Operating Costs and Expenses
Operating  costs  and  expenses  for  the  exploration  and  production  segment
increased  in the  third  quarter  and first  nine  months of 2001 due to higher
production   related   expenses  and  increased   depreciation,   depletion  and
amortization  expense.  The increase in operating  expenses was due to increased
production  volumes,  a higher level of workover  expenses and an  industry-wide
increase  in  costs  related  to  normal  production  activities.  Additionally,
increased severance and ad valorem taxes resulted from both increased production
volumes  and  higher  commodity  prices.   The  Company   anticipates  that  the
inflationary  increases in exploration  and  production  related costs that have
resulted from an overall  increase in the activity level of the domestic oil and
gas industry are  beginning to decline along with the current level of commodity
prices. The increases in depreciation,  depletion and amortization  expense were
due to the increase in production and an increase in the  amortization  rate per
unit of  production.  The full  cost  pool  amortization  rate for this  segment
averaged  $1.15 per Mcf  equivalent  for the third quarter of 2001 and $1.11 for
the first nine  months of 2001,  compared  to $1.09 per Mcf  equivalent  for the
third quarter of 2000 and $1.05 for the first nine months of 2000.

The Company utilizes the full cost method of accounting for costs related to its
oil and natural gas properties.  Under this method,  all such costs  (productive
and  nonproductive) are capitalized and amortized on an aggregate basis over the
estimated lives of the properties using the  units-of-production  method.  These
capitalized  costs are subject to a ceiling  test,  however,  which  limits such
pooled  costs to the  aggregate  of the  present  value of future  net  revenues
attributable  to proved gas and oil reserves  discounted  at 10 percent plus the
lower of cost or market value of unproved properties. At September 30, 2001, the
Company's  unamortized  costs of oil and gas  properties  exceeded  this ceiling
amount by $54.8 million due to low gas prices in effect on that date. The market
price for natural gas at Henry Hub was $1.86 on September 30, 2001. However, due
to the subsequent recovery in the market prices for natural gas, the Company was
not required to record a write-down of its oil and gas properties. The Company's
full cost ceiling is evaluated at the end of each quarter.  A decline in gas and
oil prices from current  levels,  or other  factors,  without  other  mitigating
circumstances,  could  cause a future  write-down  of  capitalized  costs  and a
non-cash charge against future earnings.

Earlier in 2001,  the Company formed a limited  partnership  with an investor to
drill and complete the first 14 development wells in the Company's Overton Field
located in Smith  County,  Texas.  This  partnership  was created to provide the
capital necessary to accelerate the field's development.  The Overton properties
were  acquired  by the  Company  in April  2000 and  have  multiple

                                     - 17 -


development  locations through the downspacing of the existing  producing units.
Because  Southwestern is the sole general partner and controls the  partnership,
operating and financial  results for the partnership are  consolidated  with the
other  operations  of the Company and the  investor's  share of the  partnership
activity is reported as a minority interest item in the financial statements.

                                Gas Distribution

Overview
The  operating  results of the  Company's  gas  distribution  segment are highly
seasonal.  This segment  typically  realizes  operating losses in the second and
third  quarters  of the year and  realizes  operating  income  during the winter
heating  season in the first and fourth  quarters.  The extent and  duration  of
heating  weather also impacts the  profitability  of this segment,  although the
Company  has a  weather  normalization  clause in its filed  rate  tariffs  that
lessens the impact of revenue  increases and  decreases  which might result from
weather  variations  during  the winter  heating  season.  The gas  distribution
segment's  profitability  is also  dependent  upon  the  timing  and  amount  of
regulatory  rate  increases  that are filed with and  approved  by the  Arkansas
Public Service Commission. For periods subsequent to allowed rate increases, the
Company's  profitability  is impacted by its ability to manage and control  this
segment's operating costs and expenses.

                                     - 18 -


On May 31, 2000, the Company completed the sale of its Missouri gas distribution
assets for $32.0 million.  The sale resulted in a pre-tax gain of  approximately
$3.2 million and proceeds  from the sale were used to pay down debt. As a result
of the adverse Hales  judgment,  the Company's Board of Directors had authorized
management  to  pursue  the sale of the  Company's  remaining  gas  distribution
operations.  The Company has  suspended the sale process as it did not result in
an acceptable bid.  Although the Company may decide to sell its gas distribution
segment  in the  future,  it  currently  plans  to  operate  these  assets  as a
continuing part of its business.

Revenues and Operating Income
Revenues  for the  three  months  ended  September  30,  2001  were  down due to
decreased  deliveries  to sales  and end use  customers  and a  decrease  in the
average sales rate, as compared to the comparable  period of 2000.  Revenues for
the nine months ended  September 30, 2001 were up primarily due to the increased
cost of gas supply.  The high cost of gas supply is reflected  in the  Company's
average rate for its utility sales which increased  during the first nine months
of 2001 to $9.14 per Mcf, up from $6.18 per Mcf for the same period in 2000. The
average sales rate for the third quarter of 2001 was $7.85 compared to $8.40 for
the same period of 2000. The prices paid for purchases of natural gas are passed
through to customers under automatic adjustment clauses.

Operating  income of the gas  distribution  segment  decreased  35% in the third
quarter of 2001 and  decreased 30% in the first nine months of 2001, as compared
to the same  periods of 2000.  The  decrease in  operating  income for the three
months ended  September 30, 2001 was primarily due to increased  operating costs
and expenses. The decrease in operating income for the nine month period was due
primarily to the impact of the sale of the Company's  Missouri gas  distribution
assets in May 2000.  Weather  during the first nine months of 2001 was 4% warmer
than normal and 17% colder  than in the same  period of 2000.  The Company has a
weather  normalization clause in its filed rate tariffs which lessens the impact
of revenue  increases  and decreases  that might result from weather  variations
during the winter heating season.

Deliveries
The  utility  systems  delivered  3.0 Bcf to sales  and  end-use  transportation
customers  during  the  third  quarter  of 2001,  down from 3.4 Bcf for the same
period in 2000.  For the nine  months  ended  September  30,  2001,  the utility
systems  delivered  17.1  Bcf to sales  and  end-use  transportation  customers,
compared to 20.7 Bcf for the same period in 2000. The decrease in deliveries for
the first nine months of 2001 was due to the sale of the Missouri properties.

Operating Costs and Expenses
The changes in  purchased  gas costs for the gas  distribution  segment  reflect
volumes  purchased,  prices  paid  for  supplies,  the  mix  of  purchases  from
intercompany  versus third party sources and the sale of the Missouri  assets as
discussed  above.  Other  operating  costs and expenses of the gas

                                     - 19 -


distribution  segment for the three months ended  September 30, 2001 were higher
due to an increase in the level of uncollectable accounts that resulted from the
exceptionally high gas costs during the previous winter heating season, and from
general inflationary increases.  Other operating costs and expenses for the nine
months ended  September 30, 2001 were lower than the  comparable  period in 2000
primarily due to the sale of the Missouri assets.

Marketing
The decrease in gas marketing revenues in the third quarter of 2001 was due to a
decrease in both gas prices and volumes marketed.  The increase in gas marketing
revenues for the nine months ended September 30, 2001,  relates to a substantial
increase in natural gas  commodity  prices from the prior year,  and was largely
offset by a comparable increase in purchased gas costs. Operating income for the
marketing segment was $.6 million for the third quarter of 2001 and $2.2 million
for the first nine months of 2001,  compared to $.5 million and $2.0 million for
the  comparable  periods in 2000.  The Company  marketed  13.5 Bcf of gas in the
third quarter of 2001 and 36.9 Bcf in the first nine months of 2001, compared to
14.6 Bcf and 48.5 Bcf for the same  periods in 2000.  The  decreases  in volumes
marketed  resulted from a planned  decrease in volumes marketed for unaffiliated
third parties.

NOARK Pipeline
The Company's  share of the NOARK pre-tax loss included in other income was $1.0
million for the first nine months of 2001, compared to $1.5 million for the same
period in 2000.

Interest Expense
Interest  expense  decreased  17% in the third quarter of 2001 and increased 10%
for the first nine months of 2001, both as compared to the same periods in 2000.
The decrease in third  quarter  interest  expense  resulted  from lower  average
borrowings and a lower average  interest rate. The increase in interest  expense
for the first nine months of 2001 was due to higher average borrowings caused by
the payment of the Hales judgment in July 2000, and a lower level of capitalized
interest.  Interest is capitalized in the exploration and production  segment on
costs that are unevaluated and excluded from amortization.

                                     - 20 -


Income Taxes
The changes in the provisions for current and deferred  income taxes recorded in
the three and nine month  periods  ended  September 30, 2001, as compared to the
same  periods in 2000,  resulted  primarily  from the  increase  in the level of
taxable  income in 2001.  Also  impacting  deferred  taxes is the  deduction  of
intangible drilling costs in the year incurred for tax purposes,  netted against
the  turnaround of intangible  drilling costs deducted for tax purposes in prior
years. Intangible drilling costs are capitalized and amortized over future years
for financial reporting purposes under the full cost method of accounting.

CHANGES IN FINANCIAL CONDITION

Changes in the Company's  financial condition at September 30, 2001, as compared
to December 31, 2000, primarily reflect the seasonal nature of the Company's gas
distribution segment and the effects of the adoption of SFAS No. 133 (See Note 5
to Consolidated Financial Statements in this Form 10-Q).

Routine capital  expenditures and scheduled debt retirements have  predominantly
been funded  through cash provided by  operations.  For the first nine months of
2001, cash provided by operating  activities was $114.7 million and exceeded the
total of these  routine  requirements.  For the nine months ended  September 30,
2000, cash used in operating  activities was $53.0 million due to the funding of
the Hales judgment. The Hales judgment, as well as routine capital expenditures,
cash  dividends  and debt  retirements  for the first  nine  months of 2000 were
funded  through a  combination  of cash  provided by  operating  activities  and
additional borrowings, as discussed in Financing Requirements.

Financing Requirements
In July 2001, the Company  arranged a new unsecured  revolving  credit  facility
with a group of banks to replace the existing  short-term  credit facility.  The
short-term  facility was put in place in July 2000 to fund the Hales judgment of
$109.3 million,  pay off the existing  revolver balance and retire $22.0 million
of private  placement debt. The new revolving  credit facility has a capacity of
$160 million and a  three-year  term.  The interest  rate on the new facility is
137.5 basis points over the current London Interbank  Offered Rate (LIBOR),  and
was 4.9% at September 30, 2001. The new credit facility contains covenants which
impose certain  restrictions  on the Company.  Under the credit  agreement,  the
Company  may not issue  total debt in excess of 75% of its total  capital,  must
maintain a certain level of shareholders'  equity, and the Company must maintain
a ratio of  earnings  before  interest,  taxes,  depreciation  and  amortization
(EBITDA) to fixed  charges of at least 3.75 or higher  through  March 30,  2002.
These covenants change over the term of the credit facility and generally become
more restrictive. At September 30, 2001, the Company's revolving credit facility
had a balance of $131.3  million and was  classified  as  long-term  debt in the
Company's balance sheet.

                                     - 21 -


During the first nine months of 2001,  the  Company's  total debt  decreased  by
$39.7 million,  as increased cash flow  generated from  operations  exceeded the
Company's capital requirements.  Total debt at September 30, 2001, accounted for
67% of the Company's capitalization, down from 74% at December 31, 2000, and the
Company's ratio of EBITDA to fixed charges for the twelve months ended September
30, 2001 was 5.5.  Excluding the effects of SFAS No. 133, the percentage of debt
to total capitalization would have been 68% at September 30, 2001.

The Company's capital  expenditures for the first nine months of 2001 were $77.1
million,  compared to $57.4  million for the same period in 2000.  The Company's
reported  capital  investments  include  the gross  expenditures  of the Overton
partnership. The minority interest partner in Overton funded $6.4 million of the
Company's reported expenditures during the period.  Additionally,  the Company's
capital  expenditures  during 2001 included $5.8 million to purchase  overriding
royalty  interests in a group of the  Company's  Arkoma Basin  properties.  This
acquisition  was made in connection  with the settlement of litigation.  Planned
capital  investments  during  calendar  year 2001 are  currently  expected to be
approximately  $100 million,  including  approximately $12 million which will be
funded by the minority interest partner in Overton.

At September 30, 2001,  NOARK had outstanding  debt totaling $74.0 million.  The
Company and the other general  partner of NOARK have  severally  guaranteed  the
principal and interest  payments on the NOARK debt.  The Company's  share of the
several guarantee is 60%.

Working Capital
Accounts  receivable  have declined since December 31, 2000, due to the seasonal
nature of the Company's gas  distribution  segment and a decrease in the amounts
owed  to the  Company's  exploration  and  production  segment  for  oil and gas
production due to lower commodity  prices.  Under-recovered  purchased gas costs
for the  Company's gas  distribution  segment were $2.1 million at September 30,
2001,  compared to $12.9  million at December 31, 2000.  Purchased gas costs are
recovered  from the Company's  utility  customers in subsequent  months  through
automatic cost of gas adjustment  clauses  included in the utility's  filed rate
tariffs.  Inventories  have  increased  due to the  injection  of gas  into  the
Company's gas storage facilities.  At September 30, 2001, the Company recorded a
current hedging asset of $8.5 million and a current  deferred income tax payable
of $3.3 million under the provisions of SFAS No. 133.

Accounts  payable has  decreased  since  December  31,  2000,  due  primarily to
decreases in gas purchase costs in the gas distribution  and marketing  segments
and to the timing of  expenditures.  Other changes in current assets and current
liabilities  between periods resulted  primarily from the timing of expenditures
and receipts.

                                     PART I

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risks relating to the Company's  operations result primarily from changes
in commodity  prices and interest rates, as well as credit risk  concentrations.
The  Company  uses  natural  gas and crude oil swap  agreements  and options and
interest rate swaps to reduce the volatility of earnings, cash flow and the cost
of purchased  gas due to  fluctuations  in the prices of natural gas and oil and
fluctuations  in  interest  rates.  The Board of  Directors  has  approved  risk
management  policies  and  procedures  to  utilize  financial  products  for the
reduction of defined  commodity  price and interest rate risks.  These  policies
prohibit   speculation   with   derivatives   and  limit  swap   agreements   to
counterparties with acceptable credit standings.

Credit Risks
The Company's financial instruments that are exposed to concentrations of credit
risk consist primarily of trade receivables and derivative  contracts associated
with  commodities  trading.  Concentrations  of  credit  risk  with  respect  to
receivables  are  limited  due  to the  large  number  of  customers  and  their
dispersion across geographic areas. No single customer accounts for greater than
5% of accounts receivable. See the discussion of commodities risk below.

Interest Rate Risk
The Company's  revolving debt  obligations  are sensitive to changes in interest
rates.  The  Company's  policy  is to manage  interest  rates  through  use of a
combination of fixed and floating rate debt.  Interest rate swaps may be used to
adjust interest rate exposures when appropriate. The Company has entered into an
interest rate swap for calendar year 2002 that allows the Company to pay a fixed
interest  rate of 5.7% on $50 million of its  outstanding  revolving  debt.  The
Company's  revolving  debt was $171.0  million at December 31, 2000,  and had an
average  interest rate of 7.8%. At September 30, 2001,  the Company's  revolving
debt was $131.3  million with an average  interest rate of 4.9%.  Other than the
Company's  revolving debt,  there have been no material  changes in the interest
rate risk information that was presented in the Company's 2000 Form 10-K.

Commodities Risk
The Company uses over-the-counter  natural gas and crude oil swap agreements and
options to hedge sales of Company production, activity in its marketing segment,
and gas  purchases in the utility  segment  against the inherent  price risks of
adverse price fluctuations or locational pricing differences between a published
index and the NYMEX (New York Mercantile  Exchange) futures market.  These swaps
and options  include (1)  transactions in which one party will pay a fixed price
(or variable price) for a notional quantity in exchange for receiving a variable
price (or fixed price) based on a published  index (referred to as price swaps),
(2)  transactions  in which  parties agree to pay a price based on two different
indices  (referred  to as  basis  swaps),  and  (3)  the  purchase  and  sale of
index-related  puts and calls (collars) that provide a "floor" price below which
the counterparty pays (production  hedge) or receives (gas purchase hedge) funds
equal to the

                                     - 24 -


amount by which the price of the commodity is below the contracted  floor, and a
"ceiling"  price above which the Company pays to (production  hedge) or receives
from (gas purchase hedge) the  counterparty the amount by which the price of the
commodity is above the contracted ceiling.

The primary market risk related to these derivative  contracts is the volatility
in market  prices for  natural gas and crude oil.  However,  this market risk is
offset by the gain or loss  recognized  upon the related sale or purchase of the
natural gas or oil that is hedged.  Credit risk relates to the risk of loss as a
result of  non-performance by the Company's  counterparties.  The counterparties
are primarily major investment and commercial  banks which  management  believes
present minimal credit risks.  The credit quality of each  counterparty  and the
level  of  financial   exposure  the  Company  has  to  each   counterparty  are
periodically reviewed to ensure limited credit risk exposure.

The  following  table  provides   information  about  the  Company's   financial
instruments  that are  sensitive  to  changes  in  commodity  prices.  The table
presents the notional  amount in Bcf  (billion  cubic feet) and MBbls  (thousand
barrels),  the weighted average  contract prices,  and the total dollar contract
amount by expected  maturity  dates.  The  "Carrying  Amount"  for the  contract
amounts are  calculated as the  contractual  payments for the quantity of gas or
oil to be  exchanged  under  futures  contracts  and do  not  represent  amounts
recorded in the  Company's  financial  statements.  The "Fair Value"  represents
values for the same contracts  using  comparable  market prices at September 30,
2001. At September 30, 2001, the "Fair Value" exceeded the "Carrying  Amount" of
these financial instruments by $10.6 million.
