                  SOUTHWESTERN ENERGY COMPANY AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 2001

1.       BASIS OF PRESENTATION

         The financial statements included herein are unaudited;  however,  such
         information  reflects  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.       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 1,109,882  shares of common stock
         with a weighted average exercise price of $13.55 per share at March 31,
         2001, and options for 1,582,916  shares with an average  exercise price
         of $11.85 per share at March 31,  2000,  that were not  included in the
         calculation   of  diluted   shares  because  they  would  have  had  an
         antidilutive effect.

3.       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.

4.       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 all derivatives 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 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 in
         place that are used to reduce the  volatility  in commodity  prices for
         the Company's forecasted oil and gas production. At March 31, 2001, the
         Company's liability related to its commodity cash flow hedges was $20.0
         million.  Additionally,  at March 31, 2001,  the Company had recorded a
         net of tax

                                      - 8 -


         cumulative  loss to other  comprehensive  income (equity section of the
         balance  sheet)  of  $12.2  million.   The  amount  recorded  in  other
         comprehensive income will be relieved over time and 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.

5.       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.

7.       Contingencies and Commitments

         In the Company's  Form 8-K filed July 2, 1996, it previously  disclosed
         that a lawsuit  relating to  overriding  royalty  interests  in certain
         Arkansas  oil and gas  properties  had been  filed.  The  Company  also
         reported in its second quarter 2000 Form 10-Q that this matter had gone
         to a  non-jury  trial  as to  liability  in  January  2000 and that the
         Company was awaiting the court's findings. The court in this matter has
         issued  Findings of Fact and  Conclusions of Law that find no fraud was
         committed.  The court also found that any  override  royalty  interests
         that may ultimately be found to be subject to the plaintiff's claim for
         additional  override  royalties accrued after March 1, 1990. All claims
         prior to March 1, 1990 have been barred by the statute of  limitations.
         The ultimate  measure of damages will be determined  during the damages
         phase of the non-jury  proceedings  that is scheduled to occur June 11,
         2001.  While the Company  anticipates  that it will owe some additional
         override  royalties  to  plaintiffs,  it  does  not  believe  that  its
         liability will be material to its financial  condition,  but in any one
         period it could be significant to its results of operations.

         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 March 31,  2001 and  December  31,  2000,  the  principal
         outstanding  for these Notes was $75.0 million.  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 million.  The proceeds
         from the issuance of the Notes were used to repay  temporary  financing
         provided by the other general partner and outstanding  amounts under an
         unsecured revolving credit agreement.  The temporary financing provided
         by the other  general  partner  was  incurred  in  connection  with the
         prepayment in early 1998 of NOARK's 9.74% Senior Secured  notes.  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

                                      -10-


         2003, and are renewable year-to-year thereafter until terminated by 180
         days' notice.

         The  Company  is  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 month period
ended March 31, 2001, and the comparable period of 2000.

RESULTS OF OPERATIONS

Net income for the three months ended March 31, 2001 was $16.0 million,  or $.64
of basic earnings per share, compared to net income of $9.2 million, or $.37 per
share,  in 2000.  Earnings  per share for 2001 on a diluted  basis were $.63 per
share.  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.

                           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.

                                      -12-


Revenues and Operating Income

Revenues for the  exploration  and production  segment were up 65% for the three
month  period  ended  March 31, 2001  compared  to the same period in 2000.  The
increases  were due to both higher gas and oil prices and  increased gas and oil
production.

Operating income for the exploration and production segment was up $13.3 million
for the three months ended March 31, 2001,  compared to the same period in 2000.
The improvements in operating income were also due to higher prices received and
increased production.

Production

Gas and oil  production  during the first  quarter of 2001 was 9.0 billion cubic
feet (Bcf)  equivalent,  up 3% from 8.7 Bcf  equivalent  for the same  period in
2000. The increase in production  resulted from new wells added in 2000 and 2001
in the Company's Arkoma Basin and Gulf Coast operating areas. Gas production was
8.0 Bcf for the first  three  months of 2001,  compared  to 7.8 Bcf for the same
period in 2000. The Company's sales to its gas distribution systems were 2.3 Bcf
during the three months  ended March 31, 2001,  compared to 3.5 Bcf for the same
period in 2000. The Company's oil production  was 161 thousand  barrels  (MBbls)
during the first quarter of 2001, up from 155 MBbls for the same period of 2000.

Commodity Prices

The Company received an average price of $4.48 per thousand cubic feet (Mcf) for
its gas  production for the three months ended March 31, 2001, up from $2.62 per
Mcf for the same period of 2000. The Company hedged 6.5 Bcf of gas production in
the first three months of 2001 primarily through zero-cost collars which had the
effect of reducing the average gas price realized during the period by $2.73 per
Mcf. On a comparative  basis, the average price during the first three months of
2000 included the negative  effect of hedges that decreased the average price by
$.06 per Mcf. Additionally,  the Company receives monthly demand charges related
to the  no-notice  service  it makes  available  to the  utility  segment  which
increases the Company's average gas price received.

For the remainder of the year 2001,  the Company has 19.2 Bcf of gas  production
hedged with collars  having an average NYMEX floor price of $3.78 per Mcf and an
average  NYMEX  ceiling  price of $4.66 per Mcf. The Company also has 1.6 Bcf of
gas  production  for the  remainder  of 2001 hedged with fixed price swaps at an
average NYMEX price of $3.55 per Mcf. For the years 2002 and 2003 combined,  the
Company has 7.2 Bcf hedged under zero-cost  collars and fixed-price  swaps.  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  $25.82  per  barrel  for its oil
production  during the three  months  ended March 31,  2001,  up from $23.03 per
barrel for the same period of 2000. For the remainder of 2001, the Company has a
collar on 225,000  barrels  with an average  floor of $27.40 per barrel,  and an
average  ceiling  of $29.95  per  barrel,  and a hedge on 54,000  barrels  at an
average NYMEX price of $17.49 per barrel.

                                      -13-


Operating Costs and Expenses

Operating  costs  and  expenses  for  the  exploration  and  production  segment
increased  in the first three  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  increase in exploration
and production  related costs that have resulted from an overall increase in the
activity  level of the domestic oil and gas industry  will  continue in the near
future. 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 $1.08 per Mcf  equivalent for the first three months of 2001,  compared
to $1.03 per Mcf equivalent in the first three 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 March 31,  2001,  the
Company's  unamortized  costs  of oil and gas  properties  did not  exceed  this
ceiling amount.  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.

                                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 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.

Note:   Amounts  and  statistics  for the three  months  ended  March 31,  2000,
        include the operations of the Company's  Missouri  properties  that were
        sold in May 2000.

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 March 31, 2001 are up from the  comparable
period  of 2000  primarily  due to the cost of gas  supply  that  has more  than
doubled when  compared to the prior year's first  quarter.  The high cost of gas
supply is reflected in the  Company's  average rate for its utility  sales which
increased  during the first three months of 2001 to $9.32 per Mcf, up from $5.47
per Mcf for the same period in 2000.  The higher  prices paid for  purchases  of
natural gas are passed through to customers under automatic adjustment clauses.

Operating  income of the gas  distribution  segment  decreased  17% in the first
quarter  of 2001,  as  compared  to the same  period of 2000.  The  decrease  in
operating income was due to the impact of the sale of the Company's Missouri gas
distribution assets in May 2000. Weather during the first quarter of 2001 was 1%
colder than  normal and 28% colder  than in the same  period of 2000.

                                      -15-


Operating  results  for the  first  quarter  of  2000,  excluding  the  Missouri
operations,  were  approximately  even with 2001 due  primarily to the Company's
weather  normalization  clause in its rates.  The weather  normalization  clause
lessens the impacts of revenue  increases and  decreases  that might result from
weather variations during the winter heating season.

Deliveries

The  utility  systems  delivered  10.5 Bcf to sales and  end-use  transportation
customers  during the three months ended March 31, 2001,  down from 12.1 Bcf for
the same period in 2000.  The decrease in deliveries  was due to the sale of the
Missouri  operations in May 2000,  offset by increased  deliveries due to colder
weather.  Excluding the effect of the Missouri  operations from the three months
ended March 31, 2000, deliveries to sales and end-use  transportation  customers
were 9.3 Bcf.

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  distribution
segment  for the quarter  ended  March 31,  2001 were lower than the  comparable
periods of the prior year due primarily to the sale of the Missouri assets.

Marketing

The  increase in gas  marketing  revenues for the three month period ended March
31, 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 $1.1 million for the first
three months of 2001,  compared to $1.0 million for the same period in 2000. The
Company marketed 11.0 Bcf of gas in the first three months of 2001,  compared to
18.2 Bcf for the same period in 2000. The decrease in volumes marketed  resulted
from a decline in volumes marketed for unaffiliated third parties.

NOARK Pipeline

The Company's  share of the NOARK Pipeline  System Limited  Partnership  (NOARK)
pre-tax loss  included in other income was $.3 million for the first  quarter of
2001, compared to $.6 million for the same period in 2000.

                                      -16-


Interest Expense

Interest  expense  increased 41% for the first quarter of 2001,  compared to the
same period in 2000, 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.

Income Taxes

The changes in the provisions for current and deferred  income taxes recorded in
the three months  ended March 31, 2001,  as compared to the same period in 2000,
resulted  primarily  from the  increase in the level of taxable  income in 2001.
Also impacting deferred taxes recorded in the three month period ended March 31,
2001, 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 March 31, 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 4
to Consolidated Financial Statements in this Form 10-Q).

Routine capital expenditures, cash dividends and scheduled debt retirements have
predominantly  been funded  through cash provided by  operations.  For the first
three months of 2001 and 2000,  cash provided by operating  activities was $40.4
and  $35.6  million,  respectively,  and  exceeded  the  total of these  routine
requirements.

Financing Requirements

In July 2000, the Company replaced its existing revolving credit facilities that
had  previously  provided the Company  access to $80.0  million of variable rate
capital  with a new  revolving  credit  facility  that has a capacity  of $180.0
million.  This new  facility  was  used 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  credit  facility  is also being used to fund
normal  working  capital  needs.  The interest rate on the new facility is 112.5
basis points over the LIBOR rate. The new credit facility has a term of 364 days
and  the  Company  intends  to  renew  or  replace  the  facility  prior  to its
termination.  At March 31, 2001, the revolving  credit facility had a balance of
$141.8  million  and was  classified  as a current  liability  in the  Company's
balance sheet.

During the first three months of 2001,  the  Company's  total debt  decreased by
$29.2 million,  due to cash flow generated from operations.  Total debt at March
31, 2001,  accounted for 72% of the Company's  capitalization,  down from 74% at
December 31, 2000. The percentage of debt to  capitalization  at March 31, 2001,
would be 70% without  consideration  of the $12.2 million of

                                      -17-


accumulated  other  comprehensive  loss  recorded in the  equity  section of the
Company's balance sheet. The other  comprehensive  loss was recorded as a result
of the adoption of SFAS No. 133 in 2001.  The Company  expects its borrowings to
continue to decrease during 2001, as a result of its anticipated  cash flow from
operating activities.

The Company's capital expenditures for the first three months of 2001 were $15.3
million,  compared to $14.6 million for the same period in 2000. Planned capital
investments during calendar year 2001 are currently expected to be approximately
$81.6 million.

At March 31, 2001, the NOARK  partnership  had  outstanding  debt totaling $75.0
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  has declined since December 31, 2000, due to a decrease in
the amounts owed the Company's  exploration and production segment for its March
2001  production.  The  decrease  was due to lower  commodity  prices  realized.
Under-recovered  purchased gas costs for the Company's gas distribution  segment
were $12.2 million at March 31, 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.  At March 31, 2001, the Company had a deferred
income tax benefit of $6.6  million  and a current  hedging  liability  of $17.0
million  resulting  from entries  recorded as a result of 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.  The increase in other current liabilities is
primarily due to advances  received from joint venture  partners for exploration
and  development  projects  where the Company is the operator.  Other changes in
current assets and current  liabilities  between periods resulted primarily from
the  timing  of  expenditures  and  receipts  and the sale of the  Missouri  gas
distribution assets in 2000.

                                     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 to reduce the  volatility of earnings and cash flow due to  fluctuations
in the prices of natural gas and oil. The Board of Directors  has approved  risk
management  policies  and  procedures  to  utilize  financial  products  for the
reduction of defined commodity price 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
3% of accounts  receivable.  See the discussion of credit risk  associated  with
commodities trading below.

Interest Rate Risk

     The  Company's  short-term  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.  There were no interest rate
swaps  outstanding at March 31, 2001. The Company's  short-term  debt was $171.0
million at December 31, 2000 and had an average interest rate of 7.83%. At March
31,  2001,  the  Company's  short-term  debt was $141.8  million with an average
interest rate of 6.30%.  Other than the Company's  short-term  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 and marketing activity 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 the Company the
amount by which the price of the commodity is below the  contracted  floor and a
"ceiling"  price  above which the Company  pays the  counterparty  the amount by
which the price of the commodity is above the contracted ceiling.

                                      -20-


     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 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),  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 March 31,  2001.  At March  31,  2001,  the
"Carrying  Amount" of these financial  instruments  exceeded the "Fair Value" by
$20.0 million,  which represents the total obligation recorded by the Company at
March 31, 2001.

                                OTHER INFORMATION

Item 1

In the Company's  Form 8-K filed July 2, 1996, it  previously  disclosed  that a
lawsuit relating to overriding royalty interests in certain Arkansas oil and gas
properties had been filed.  The Company also reported in its second quarter 2000
Form 10-Q that this  matter  had gone to a  non-jury  trial as to  liability  in
January 2000 and that the Company was awaiting the court's  findings.  The court
in this matter has issued  Findings of Fact and  Conclusions of Law that find no
fraud was committed.  The court also finds that any override  royalty  interests
that  may  ultimately  be found  to be  subject  to the  plaintiff's  claim  for
additional  override  royalties accrued after March 1, 1990. All claims prior to
March 1, 1990 have been  barred by the  statute  of  limitations.  The  ultimate
measure of damages will be  determined  during the damages phase of the non-jury
proceedings  that is  scheduled  to  occur  June 11,  2001.  While  the  company
anticipates that it will owe some additional  override  royalties to plaintiffs,
it does not  believe  that  its  liability  will be  material  to its  financial
condition,  but in any one  period it could be  significant  to its  results  of
operations.
