Part I

ITEM 1. BUSINESS

         Southwestern  Energy  Company (the "Company" or  "Southwestern")  is an
energy company primarily focused on natural gas. The Company was incorporated in
Arkansas in 1929 as a local gas distribution company. Today,  Southwestern is an
exempt holding  company under the Public Utility Holding Company Act of 1935 and
derives the vast majority of its operating income and cash flow from its oil and
gas  exploration  and  production  business.  The  Company  is  involved  in the
following business segments:

1.       Exploration   and   Production   -  Engaged  in  natural  gas  and  oil
         exploration,  development and production,  with operations  principally
         located in Arkansas,  Oklahoma,  Texas, New Mexico, and Louisiana. This
         represents the Company's primary business.
2.       Natural Gas Distribution - Engaged in  the gathering,  distribution and
         transmission of natural gas to approximately
         136,000 customers in Arkansas.
3.       Marketing and  Transportation - Provides  marketing and  transportation
         services  in the  Company's  core  areas  of  operation  and owns a 25%
         interest in the NOARK Pipeline System, Limited Partnership (NOARK).

         This Report on Form 10-K includes certain statements that may be deemed
to be  "forward-looking  statements"  within the  meaning of Section  27A of the
Securities Act of 1933 and Section 21E of the  Securities  Exchange Act of 1934.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations"  in Part II, Item 7 of this Report for a discussion  of factors that
could cause actual results to differ  materially  from any such  forward-looking
statements.

Business Strategy
         The Company's  business strategy is to provide long-term growth through
focused  exploration and production of oil and natural gas. The Company seeks to
maximize  cash flow and  earnings and provide  consistent  growth in oil and gas
production and reserves through the discovery,  production and marketing of high
margin  reserves  from a balanced  portfolio  of  drilling  opportunities.  This
balanced portfolio  includes low risk development  drilling in the Arkoma Basin,
moderate risk  exploration and exploitation in the Permian Basin and east Texas,
and high potential exploration opportunities in the onshore Gulf Coast.

         Additionally,  the Company creates additional value through its natural
gas  distribution,   marketing  and  transportation  activities.   During  2000,
Southwestern  announced  its  intent  to  sell  its gas  distribution  business.
However,  the Company has not  received an offer that it believes  reflects  the
true value of the utility  system.  Accordingly,  Southwestern  will continue to
hold and operate these assets. The Company further enhances shareholder value by
creating  and  capturing  additional  value  beyond  the  wellhead  through  its
marketing and transportation activities.

EXPLORATION AND PRODUCTION

         In 1943, the Company commenced a program of exploration and development
of natural  gas  reserves in Arkansas  for supply to its utility  customers.  In
1971,  the Company  initiated an exploration  and  development  program  outside
Arkansas,  unrelated  to  the  utility's  requirements.  Since  that  time,  the
Company's exploration and development  activities outside Arkansas have expanded
substantially.

                                       3

         During 1998,  Southwestern  brought in new senior operating  management
and  replaced  over  50% of its  professional  technical  staff to  refocus  its
exploration and production segment. Additionally in 1998, the Company closed its
Oklahoma  City office and moved  these  operations  to its Houston  office in an
effort to increase future  profitability.  The segment was also reorganized into
asset  management  teams to provide an area specific  focus in  exploration  and
development projects and a new incentive compensation system was put in place to
more  closely   align  its   employees'   efforts  with  the  interests  of  its
shareholders.  As a result  of these  changes,  the  operating  results  of this
business segment have improved  substantially,  with results in 2000 some of the
best in the Company's history.

         At December  31,  2000,  the Company had proved oil and gas reserves of
380.5 billion cubic feet (Bcf) equivalent, including proved natural gas reserves
of 331.8 Bcf and proved oil  reserves of 8,130  thousand  barrels  (MBbls).  The
Company's reserve life index  approximated 10.7 years at year-end 2000, with 82%
of total reserves classified as proved developed.  All of the Company's reserves
are located  entirely within the United States.  Revenues of the exploration and
production  subsidiaries are predominately  generated from production of natural
gas. Sales of gas production  accounted for 82% of total operating  revenues for
this segment in 2000, 87% in 1999 and 89% in 1998.

Areas of Operation
         Southwestern  engages in gas and oil exploration and production through
its subsidiaries,  SEECO, Inc. (SEECO),  Southwestern  Energy Production Company
(SEPCO),  and  Diamond  "M"  Production  Company  (Diamond  M).  SEECO  operates
exclusively  in the state of Arkansas  and holds a large base of both  developed
and  undeveloped  gas reserves and conducts an ongoing  drilling  program in the
historically  productive  Arkansas  part of the  Arkoma  Basin.  SEPCO  conducts
development  drilling and  exploration  programs in the Oklahoma  portion of the
Arkoma Basin,  the Permian Basin of Texas and New Mexico,  the Anadarko Basin of
Oklahoma,  Louisiana,  and Texas.  Diamond M operates  properties in the Permian
Basin of Texas.

         The following table provides December 31, 2000 information as to proved
reserves,  well count, and gross and net acreage, and 2000 annual information as
to  production,  capital  expenditures  and  reserve  additions  for each of the
Company's core operating areas.

         Arkoma  Basin.  The Arkoma Basin  provides a solid  foundation  for the
Company's  exploration and production  program and represents the primary source
of production  and reserves for the Company.  At December 31, 2000,  the Company
had  approximately  200.3 Bcf of  natural  gas  reserves  in the  Arkoma  Basin,
representing 60% of the Company's natural gas reserves and 53% of total reserves
on a Bcf equivalent  (Bcfe) basis.  The Company  participated in 42 wells during
2000 with a 76%  success  ratio and an  average  working  interest  of 47%.  The
Company's  Arkoma  drilling  program added 18.4 Bcf of gas reserves at a finding
and development  cost of $0.97 per thousand cubic feet (Mcf).  Average net daily
production in 2000 was 54.6 million cubic feet (MMcf).

         The Company's  strategy in the Arkoma is to annually replace production
from the basin with new  reserves at a finding  cost of under $1.00 per Mcf. The
Company intends to continue that strategy by investing approximately $21 million
and drilling approximately 50 wells in the basin in 2001.

         Southwestern's   Arkoma  Basin   operations   continue  to  generate  a
significant amount of the Company's cash flow. Production,  or lifting, costs in
the basin  continued to be extremely low during 2000 at $.24 per Mcf  (including
production taxes). After direct general and administrative  expenses of $.14 per
Mcf, Southwestern's netback per Mcf after cash operating expenses was 88% of the
average price it received for its Arkoma production in 2000.

         Southwestern's  traditional  operating  area over the years has been in
the "fairway" portion of the basin,  which is primarily within the boundaries of
the Company's  utility  gathering  system.  The Company's  strategy in this core
producing  area  is to  delineate  new  geologic  plays  and  extend  previously
identified trends using Southwestern's extensive databank of regional structural
and stratigraphic maps.  Southwestern  completed five wells out of seven drilled
in the fairway in 2000 that added 6.1 Bcf of new reserves.  The largest  success
in this area was the Sexton #1-20 well in Johnson  County,  Arkansas.  This well
was placed on production in February 2000 at 3.6 MMcf of gas per day (MMcfd) and
added  3.3 Bcf of new  reserves  in 2000.  Southwestern  plans to drill up to 13
wells in the fairway portion of the basin in 2001.

         In recent  years,  Southwestern  has extended its  development  program
outside  of the  traditional  fairway  area to  continue  its  growth.  In 1998,
Southwestern drilled its first exploratory well at its Ranger Anticline prospect
area,  located in the southern edge of the Arkansas  portion of the basin.  This
prospect area features a complex series of thrusted  anticlinal folds containing
deepwater Pennsylvanian sands. To date, the Company has successfully drilled six
out  of  nine  wells  in  this  prospect,  adding  9.9  Bcf of  reserves  net to
Southwestern's interest at a finding cost of $.56 per Mcf. In December 2000, the
Company  secured  20,200 net federal  acres with a 10-year lease term to further
develop this play. Southwestern plans to drill up to six wells here in 2001.

         In 2000,  Southwestern  built on its  initial  drilling  success in new
discovery  areas such as Cherokee and  Haileyville in eastern  Oklahoma.  In the
Cherokee prospect area in LeFlore County, the Company successfully drilled eight
wells out of nine in 2000. At  Haileyville,  three wells out of the four drilled
were completed,  including the Collins #1-13 well, which is currently  producing
over 7.2 million cubic feet of gas per day (MMcfd).  The Company  believes there
is significant  potential that is currently  untapped in this area of the basin,
and these prospects will be focus areas in 2001.

         Mid-Continent.  The  Company's  activities in this region are primarily
focused on the Anadarko Basin of Oklahoma. At December 31, 2000, the Company had
approximately  24.4 Bcf of natural gas  reserves and 1,759 MBbls of oil reserves
in the region, representing 7% and 22%, respectively, of the Company's total gas
and oil reserves.  Average net daily  production in 2000 for this region was 9.6
MMcf equivalent (MMcfe). Southwestern does not expect its

                                       5

Mid-Continent  operations  to be a  primary  area of future  growth,  due to its
efforts to concentrate on those areas where it has a competitive advantage.  The
Company  intends to produce these  properties  to depletion,  sell them or trade
them for properties in the Company's  core areas of operation.  During 2000, the
Company sold at auction a portion of its  properties in the  Mid-Continent  area
with proved reserves of 13.8 Bcfe for approximately $13.1 million.

         Texas/New Mexico. The Company has key operations in the states of Texas
and New Mexico, and is primarily focused here on the Permian Basin in west Texas
and  southeast  New Mexico,  the onshore  Texas Gulf Coast and a newly  acquired
producing  field in east Texas.  At December 31, 2000,  Southwestern  had proved
reserves of 82.2 Bcf of gas and 5,176  MBbls of oil in the region,  representing
25% and 64%, respectively, of the Company's total gas and oil reserves.

         Over the past three years,  Southwestern has made meaningful strides in
establishing  itself as a significant  player in the Permian Basin.  At December
31, 2000, Southwestern had proved reserves of 38.2 Bcf of gas and 4,670 MBbls of
oil in the basin, or 66.2 Bcfe. The Company successfully  completed 43 out of 57
wells  drilled  in the  Permian  in 2000,  resulting  in a success  rate of 75%.
Southwestern's  average  working  interest in the  Permian  during 2000 was 27%.
Average net daily  production in the basin was 27.1 MMcfe and production  costs,
including production taxes, averaged $.77 per Mcf equivalent (Mcfe) during 2000.

         Southwestern  continued to develop its Logan Draw prospect area in Eddy
County,  New Mexico,  successfully  completing 10 out of 13 wells there in 2000.
Southwestern  has  an  average  working  interest  of  32%  in  the  Logan  Draw
development  area, which is the combination of the Company's Top Dog, Amber, and
Freight Train  prospects.  To date, the Company has drilled 21 successful  wells
out of 26 and has added 8.1 Bcfe of reserves at a finding cost of $.84 per Mcfe.

         In late 1999, the Company  entered into a joint  exploration  agreement
with Phillips  Petroleum to explore for deeper  formations under acreage that is
held-by-production in southeast New Mexico. This initial joint venture agreement
spawned  the  development  of two more joint  exploration  agreements  that were
consummated in late 2000, one with Energen Resources and a second agreement with
Phillips. In total, these agreements provide the Company access to an additional
98,700  gross  acres to pursue  drilling  opportunities.  Under each  agreement,
Southwestern's  partners  have a  deferred  election  clause  at  casing  point,
allowing them to retain a pre-specified working interest share.  Southwestern is
the  operator of all wells under the  agreements.  These  agreements  have terms
ranging  from  12 to  21  months,  and  each  has  continuous  drilling  options
thereafter. To date, the Company has drilled nine out of eleven successful wells
under  these joint  ventures,  and plans to drill at least six wells under these
agreements in 2001.

         One  meaningful  discovery  resulting  from the  first  Phillips  joint
venture is the Company's oil discovery at its Bimini prospect in Lea County, New
Mexico.  The  Company  was  successful  on five wells out of five  drilled,  and
together the wells are currently producing 450 barrels of oil per day (Bopd) and
480 MMcfd from the Blinebry  formation.  The  discovery at Bimini has set up two
additional  prospect areas with similar  Blinebry  potential that will be tested
during 2001. The Company also had discoveries in 2000 at its Heisman and Outland
prospects under this agreement with follow-up drilling planned for these areas.

         The Company entered the prolific  gas-producing area of east Texas with
the  acquisition  of producing  properties in the Overton Field in Smith County,
Texas in April 2000. This transaction  creates an additional low-risk multi-year
development  drilling  program for the Company and is discussed more fully below
under "Acquisitions."

                                       6

         Louisiana.  Southwestern  began its drilling program in south Louisiana
in 1996 and this  area  continues  to be the main  focus  area of the  Company's
high-impact  exploration  activities.  At December  31, 2000,  Southwestern  had
proved  reserves  of  24.9  Bcf of gas  and  1,195  MBbls  of oil in the  state,
representing  8% of the  Company's  total  reserves on a gas  equivalent  basis.
Average net daily  production  in this area was 6.6 MMcfe and  production  costs
(including production taxes) averaged $.87 per Mcfe during 2000.

         The Company has an extensive  inventory  of 3-D seismic  data  covering
over 1,230 miles in Louisiana.  From this  extensive 3-D database,  Southwestern
has internally generated a multi-year  inventory of exploration  prospects to be
drilled in 2001 and  beyond.  The Company  also  continues  to gain  exposure to
additional 3-D seismic data for future drilling opportunities.

         Southwestern  has  been  successful  in  four  out  of  its  last  five
exploration  wells in this area,  beginning with its first  internally-generated
discovery in December  1999 at its Gloria  prospect in  Assumption  Parish.  The
Dugas &  LeBlanc  #1 well was  placed  on  production  in  February  2000 and is
currently  producing  9.6 MMcfd and 310  barrels of  condensate  per day (Bcpd).
Southwestern is the operator of the well and holds a 50% working interest.

         The Company  announced in February  2000 that it had made a significant
discovery at its North Grosbec prospect,  also in Assumption  Parish,  which has
resulted  in one of the  largest  discoveries  in  the  Company's  history.  The
Brownell-Kidd  #1 well was  placed on  production  in May 2000 and is  currently
producing 16.2 MMcfd and 575 Bcpd.  The Company holds a 25% working  interest in
this well which is operated by Petro-Hunt, L.L.C. Southwestern plans to drill up
to two  additional  development  wells at North  Grosbec  in 2001 to  facilitate
efficient depletion of the reservoir.

         After drilling a dry hole at its Brigadoon  prospect,  the Company made
another gas discovery in its Eden 3-D project area.  The Eden 3-D project was an
alliance formed with industry partners to jointly explore a 146-mile proprietary
3-D seismic survey in the Nodosaria Embayment area of Lafayette,  St. Landry and
Acadia Parishes.  The Company's first well drilled in the project, the Robertson
#1, was placed on production in late-December 2000 and is currently producing at
6.8 MMcfd  and 317 Bcpd.  Southwestern  operates  the well with a 27.5%  working
interest.  The Company plans to drill two  additional  exploratory  tests in its
Eden 3-D project area in 2001 and has  identified  several  additional  prospect
leads for 2002.

         In January  2001,  Southwestern  announced  a  discovery  at its Malone
prospect,  located south of the Company's Gloria discovery in Assumption Parish.
The SL  16626  #1 well  encountered  approximately  260  feet of gas pay in five
separate  productive  sands  within  the  Miocene  formation.   Southwestern  is
currently  completing  this well and plans to have it  placed on  production  in
March. After drilling the initial discovery well, an offset development well was
immediately drilled and reached total depth in February. Logs indicate favorable
pay  development and the Company expects this well to be placed on production by
May.  Southwestern  has a 33  percent  working  interest  in this  prospect  and
believes that it represents a significant gas accumulation.

Acquisitions
         In April 2000, the Company purchased the Overton Field in Smith County,
Texas, from Total Fina Elf for $6.1 million. Proved developed producing reserves
associated  with the purchase  were 7.5 Bcfe,  for a purchase  price of $.81 per
Mcfe.  The  purchase  included  16 active gas wells in 13 spacing  units,  8,800
contiguous  acres in established  units and 2,000 additional  undeveloped  acres
outside  the  units.  The  Overton  Field  represents  a  significant   low-risk
development opportunity for Southwestern, as it is one of the last Cotton Valley
Sand fields in east Texas that has not been  downspaced  from original  640-acre
units.  Currently,  adjacent  gas-producing  fields  in the area are  spaced  at
80-acre to 160-acre units.

                                       7

Southwestern  plans  to  drill  between  8 and 14  wells  in the  field in 2001,
primarily  targeting the Cotton Valley Taylor Sand formation  above 12,000 feet.
Based on the well  performance of the initial  development  phase,  there is the
potential for 22 to 38 additional  development  locations to be drilled over the
next few years based upon 160-acre unit spacing.

         In 1999,  the Company  purchased  producing  properties  in the Permian
Basin with estimated  proved  reserves of 9.4 Bcf of gas and 576 MBbls,  or 12.9
Bcfe. The properties were purchased from  Petro-Quest  Exploration,  a privately
held company headquartered in Midland,  Texas, for $9.4 million. The Company did
not make any  producing  property  acquisitions  in 1998 or 1997.  In 1996,  the
Company acquired approximately 32.7 Bcf of gas and 6,350 MBbls of oil located in
Texas and Oklahoma  for $45.8  million.  The  Company's  current  strategy is to
pursue selective acquisitions that would complement its existing operations.

Capital Spending
         The Company  invested a total of $69.2 million in its  exploration  and
production  program during 2000, and  participated  in a total of 105 wells,  of
which 78 were  successful.  The Company's  investments were balanced between the
Company's core areas of operations, with approximately $17.6 million invested in
the Arkoma  Basin,  $27.7  million  in the  Texas/  New Mexico  region and $23.9
million for exploration,  primarily in south Louisiana.  Of these  expenditures,
approximately  $19.3 million was invested in exploration wells, $23.8 million in
development  drilling  and  workovers,  $5.1  million  for  land  and  leasehold
acquisition,  $4.1 million in seismic  expenditures,  $6.7 million for producing
property  acquisitions and $10.2 million in capitalized  interest,  expenses and
other technology-related expenditures.

         In 2001, the Company's capital budget for exploration and production is
$75.0 million,  with approximately 75% of this capital dedicated to drilling. As
in 2000, the Company's  investments will again be balanced between the Company's
core areas of  operations,  with  approximately  $20.5 million  allocated to the
Company's  low-risk  development  activities in the Arkoma Basin,  $30.3 million
allocated to medium-risk  exploration and  exploitation in the Texas/New  Mexico
area,  and  $24.2  million  allocated  to  high-potential  exploration  in south
Louisiana.  Of the $75.0 million capital budget,  approximately $23.7 million is
allocated to  exploration  wells,  $32.3 million to development  drilling,  $4.7
million  for  land  and   leasehold   acquisition,   $3.3  million  for  seismic
expenditures,   and  $11.0  million  in  capitalized   interest,   expenses  and
technology-related  items.  Although no capital was budgeted for acquisitions in
2001, the Company will continue to seek producing  property  acquisitions in its
core producing  areas that would  complement its overall  strategy.  The Company
expects to maintain  its  capital  investments  within the limits of  internally
generated cash flow, and will adjust its capital program accordingly.

Sales and Major Customers
         Natural gas  equivalent  production  averaged  97.7 million  cubic feet
equivalent  per day (MMcfed) in 2000,  compared to 90.2 MMcfed in 1999 and 101.1
MMcfed in 1998. The Company's gas  production was 31.6 Bcf in 2000,  compared to
29.4 Bcf in  1999,  and 32.7 Bcf in 1998.  The  Company  also  produced  676,000
barrels of oil in 2000, compared to 578,000 barrels in 1999, and 703,000 barrels
in  1998.  The  decreases  in  production  in 1999  were  the  result  of  lower
non-operated  production due to the industry slowdown during late 1998 and early
1999,  the decline in  production  from certain wells in the Gulf Coast area and
production  losses from marginal  properties that were sold during the year. The
Company expects its equivalent  production in 2001 to increase  approximately 7%
over the level in 2000.

         The Company's natural gas production realized an average wellhead price
of $2.88 per Mcf in 2000, compared to $2.21 per Mcf in 1999 and $2.34 per Mcf in
1998.  The Company's  average oil price  realized was $22.99 per barrel in 2000,
compared to $17.11 per barrel in 1999 and $13.60 per barrel in 1998.

         Southwestern's  largest single customer for sales of its gas production
is the Company's  utility  subsidiary,  Arkansas  Western Gas Company  (Arkansas
Western).  Sales from SEECO to Arkansas Western  accounted for approximately 24%
of

                                       8

total exploration and production  revenues in 2000, 31% in 1999 and 38% in 1998.
All of the Company's  remaining  sales are to unaffiliated  purchasers.  SEECO's
sales to Arkansas Western were 7.8 Bcf in 2000,  compared to 8.2 Bcf in 1999 and
11.3 Bcf in 1998. The decrease in affiliated gas sales in 1999 was the result of
warmer  weather in the  utility's  service  territory  combined with the loss of
certain intercompany gas supply contracts.

         Gas  volumes  sold by  SEECO  to  Arkansas  Western  for its  northwest
Arkansas  division  (AWG)  were 5.1 Bcf in 2000 and  1999,  and 7.7 Bcf in 1998.
Through these sales,  SEECO  furnished 36% of the  northwest  Arkansas  system's
requirements  in  2000,  38% in  1999  and 55% in  1998.  SEECO  also  delivered
approximately 2.8 Bcf in 2000, 2.6 Bcf in 1999 and 2.0 Bcf in 1998,  directly to
certain large business customers of AWG through a transportation  service of the
utility subsidiary.

         Prior to 1999,  most of the sales to AWG were pursuant to a twenty-year
contract between SEECO and AWG, entered into in July 1978, under which the price
was frozen between 1984 and 1994.  This contract was amended in 1994 as a result
of a settlement  reached to resolve  certain gas cost issues before the Arkansas
Public Service Commission.  This contract expired July 24, 1998 but continued on
a month-to-month basis through November 1998.

         In March  1997,  AWG filed a gas supply plan with the  Arkansas  Public
Service  Commission  (APSC)  which  projected  system load growth  patterns  and
long-range gas supply needs for the utility's northwest Arkansas system. The gas
supply plan also addressed  replacement  supplies for AWG's  long-term  contract
with SEECO.  After discussions with the APSC it was determined that the majority
of  the  utility's  future  gas  supply  needs  should  be  provided  through  a
competitive bidding process. On October 1, 1998, AWG sent requests for proposals
to various suppliers  requesting bids on seven different  packages of gas supply
to be effective December 1, 1998. These bid requests included replacement of the
gas supply and no-notice service previously provided by the long-term gas supply
contract between AWG and SEECO. Eleven potential suppliers returned bids in late
October.

         SEECO along with the Company's marketing subsidiary successfully bid on
five of the original  seven  packages  with prices based on the NorAm East Index
plus a demand  charge.  The  volumes of gas  projected  to be sold  under  these
contracts in their first year were approximately  equal to the historical annual
volumes sold under the expired  long-term  contracts,  assuming  normal  weather
patterns.  However,  the volumes to be sold under these  contracts are not fixed
and will fluctuate with the weather-related requirements of AWG. These contracts
provide more of the gas needed  during  periods of colder  weather,  and less of
AWG's base system needs. As a result, periods of abnormally warmer weather, such
as in 1999 and  1998,  result  in lower  deliveries  to AWG by  SEECO.  However,
charges for no-notice service  associated with these contracts are approximately
$6.0 million per year and are received by SEECO regardless of weather  patterns.
Other sales to AWG are made under  long-term  contracts  with  flexible  pricing
provisions.  Two of the five  original gas  supplying  packages have come up for
rebid  since  1998  and  were not  awarded  to  SEECO.  These  packages  provide
approximately  2.5 Bcf of AWG's  annual gas  supply.  There were no demand  fees
associated with the two contracts not renewed. In 2001, AWG will again perform a
competitive  bidding  process for its  primary gas supply  needs and the Company
expects its subsidiaries to aggressively  bid to retain the contracts  currently
in place.

         SEECO's  sales  to  Associated  Natural  Gas  Company  (Associated),  a
division of Arkansas Western which operates a natural gas distribution system in
northeast  Arkansas,  were 2.7 Bcf in 2000, 3.1 Bcf in 1999 and 3.6 Bcf in 1998.
These  deliveries   accounted  for  approximately  51%  of  Associated's   total
requirements  in 2000, 42% in 1999 and 46% in 1998. The decrease in 2000 volumes
delivered was due to  Southwestern's  sale of its Missouri utility assets in May
2000,  as discussed  below in "Natural  Gas  Distribution,"  somewhat  offset by
colder than normal  weather in November and December  2000. The decrease in 1999
was due to record warm weather.  Effective  October  1990,  SEECO entered into a
ten-year contract with Associated to supply a portion of its system requirements
at a price  to be  redetermined  annually.  For the  contract  period  beginning
October 1, 1997, the contract was revised to redetermine the sales price monthly
based on an index

                                       9

posting plus a reservation fee.  Effective  October 2000,  Associated placed its
gas supply  out for  competitive  bids.  SEECO was  successful  in  obtaining  a
one-year bid to supply  approximately  1.0 Bcf of gas, or  approximately  40% of
Associated's annual requirement assuming normal weather patterns.

         At  present,  SEECO's  contracts  for  sales  of  gas  to  unaffiliated
customers  consist  of  short-term  sales  made  to  customers  of  the  utility
subsidiary's  transportation  program and spot sales into  markets away from the
utility's distribution system. These sales are subject to seasonal price swings.
SEECO's sales to  unaffiliated  customers are also affected by the demand of the
utility for production on its gathering  system.  SEECO's sales to  unaffiliated
purchasers  accounted for  approximately 29% of total exploration and production
revenues in 2000, 28% in 1999 and 19% in 1998.

         The  combined  gas  production  of SEPCO and  Diamond M was 13.8 Bcf in
2000,  compared to 10.5 Bcf in 1999 and 13.2 Bcf in 1998. Oil production was 676
MBbls in 2000,  compared to 578 MBbls in 1999 and 703 MBbls in 1998. SEPCO's and
Diamond M's gas and oil  production is sold under  contracts  with  unaffiliated
purchasers  which  reflect  current  short-term  prices and which are subject to
seasonal  price  swings.  SEPCO's  and Diamond  M's  combined  gas and oil sales
accounted for 47% of total  exploration and production  revenues in 2000, 41% in
1999 and 43% in 1998.

         The Company periodically enters into hedging activities with respect to
a portion  of its  projected  crude oil and  natural  gas  production  through a
variety of  financial  arrangements  intended  to support  oil and gas prices at
targeted levels and to minimize the impact of price fluctuations.  The Company's
policies  prohibit  speculation  with  derivatives  and limit swap agreements to
counterparties  with  appropriate  credit  standings.  At December 31, 2000, the
Company  had hedges in place on 34.7 Bcf of future gas  production  and  697,000
barrels of future oil  production.  Subsequent to December 31, 2000, the Company
closed its position on 298,000 barrels of 2001 oil production with a floor price
of $18.00. The Company currently has hedges in place on approximately 80% of its
2001  anticipated gas production and  approximately  50% of its 2001 anticipated
oil production.  See Item 7.A. of this Form 10-K,  "Quantitative and Qualitative
Disclosures About Market Risk," for further information  regarding the Company's
hedge position at December 31, 2000.

Competition
         All  phases  of the  gas  and  oil  industry  are  highly  competitive.
Southwestern  competes  in the  acquisition  of  properties,  the search for and
development of reserves, the production and sale of gas and oil and the securing
of the  labor and  equipment  required  to  conduct  operations.  Southwestern's
competitors  include major gas and oil companies,  other independent gas and oil
concerns and individual producers and operators.  Many of these competitors have
financial  and other  resources  that  substantially  exceed those  available to
Southwestern.  Gas and oil  producers  also compete with other  industries  that
supply  energy and fuel.  During 2000 the impact of  inflation  and  competition
intensified  as shortages in drilling  rigs,  third party services and qualified
labor developed due to an overall increase in the activity level of the domestic
oil and gas industry.  The Company  anticipates that inflationary  pressures and
industry competition will continue to increase for the foreseeable future.

         Competition in the state of Arkansas has increased in recent years, due
largely to the  development of improved access to interstate  pipelines.  Due to
the  Company's  significant  leasehold  acreage  position  in  Arkansas  and its
long-time  presence and  reputation in this area,  the Company  believes it will
continue to be successful in acquiring  new leases in Arkansas.  While  improved
intrastate and interstate  pipeline  transportation  in Arkansas should increase
the  Company's  access to markets for its gas  production,  these  markets  will
generally  be served by a number of other  suppliers.  Thus,  the  Company  will
encounter  competition  that may affect both the price it receives  and contract
terms it must offer. Outside Arkansas, the Company is less established and faces
competition from a larger number of other  producers.  The Company has in recent
years been  successful  in building  its  inventory  of  undeveloped  leases and
obtaining  participating  interests  in drilling  prospects in its core areas of
operations.

NATURAL GAS DISTRIBUTION

         The  Company's   subsidiary   Arkansas  Western  Gas  Company  operates
integrated natural gas distribution systems  concentrated  primarily in northern
Arkansas.  The APSC regulates the Company's  utility rates and  operations.  The
Company serves approximately 136,000 customers and obtains a substantial portion
of the gas they consume through its Arkoma Basin gathering facilities.

         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. The gas distribution  statistics  discussed below include the results from
the Company's Missouri utility operations through May 2000.

         In June 2000,  Southwestern  announced its intent to sell its remaining
utility  operations in Arkansas to fund a $109.3  million  judgment  against the
Company  (Hales  judgment).  The Company hired Morgan Stanley Dean Witter as its
investment  advisor to manage  the  auction  process  and the  Company  received
several  serious  expressions  of interest from bona fide parties.  However,  to
date,  the Company has not received an offer that it believes  reflects the true
value of the utility system. Accordingly, Southwestern will continue to hold and
operate  these  assets.  Absent  a sale of its  utility  assets,  the  Company's
strategy is to utilize cash flow in excess of its capital requirements to reduce
the debt incurred as a result of the Hales  judgment.  As part of this strategy,
the Company has hedged  approximately 80% of its 2001 anticipated gas production
and  50% of its  2001  anticipated  oil  production  at  attractive  prices  (as
discussed  previously under "Exploration and Production") to ensure that it will
have cash flow available to reduce the debt level.

         Arkansas Western consists of two operating divisions.  The AWG division
gathers  natural  gas in the  Arkansas  River  Valley of  western  Arkansas  and
transports  the gas  through  its own  transmission  and  distribution  systems,
ultimately  delivering  it at  retail  to  approximately  115,000  customers  in
northwest Arkansas. The Associated division receives its gas from transportation
pipelines  and delivers the gas through its own  transmission  and  distribution
systems, ultimately delivering it at retail to approximately 21,000 customers in
northeast Arkansas.  Associated,  formerly a wholly-owned subsidiary of Arkansas
Power and Light Company, was acquired and merged into Arkansas Western effective
June 1, 1988.

Gas Purchases and Supply
         AWG  purchases  its  system gas supply  through a  competitive  bidding
process  implemented  in late 1998,  as  discussed  above,  and  directly at the
wellhead under long-term contracts.  SEECO furnished  approximately 36% of AWG's
system requirements in 2000, 38% in 1999 and 55% in 1998. AWG also purchases gas
from unaffiliated producers under take-or-pay contracts.  Currently, the Company
believes that it does not have a significant exposure to take-or-pay liabilities
resulting from these  contracts.  The Company  expects to be able to continue to
satisfactorily manage its exposure to take-or-pay liabilities.

         Associated  purchases  gas  for its  system  supply  from  unaffiliated
suppliers accessed by interstate  pipelines and from affiliates.  Purchases from
unaffiliated suppliers are under firm contracts with terms between one and three
years. The rates charged by most suppliers  include demand  components to ensure
availability of gas supply, administrative fees, and a commodity component which
is based on monthly  indexed  market  prices.  Associated's  gas  purchases  are
transported through four pipelines.  The pipeline  transportation  rates include
demand  charges to reserve  pipeline  capacity and  commodity  charges  based on
volumes transported.  Associated has also contracted with an interstate pipeline
for storage capacity to meet its peak seasonal demands.  These contracts involve
demand charges based on the maximum  deliverability,  capacity  charges based on
the  maximum  storage  quantity,  and charges for the  quantities  injected  and
withdrawn.

                                       11

         AWG  has  no  restriction  on  adding  new  residential  or  commercial
customers and will supply new industrial  customers that are compatible with the
scale of its  facilities.  AWG has never denied service to new customers  within
its service area or experienced  curtailments because of supply constraints.  In
addition,  Associated  has never  denied  service  to new  customers  within its
service area or experienced curtailments because of supply constraints since the
acquisition  date.   Curtailment  of  large  industrial  customers  of  AWG  and
Associated  occurs only  infrequently  when extremely cold weather requires that
systems be dedicated exclusively to human needs customers.

         The gas distribution  subsidiary's rate schedules include purchased gas
adjustment  clauses  whereby the actual cost of purchased gas above or below the
level  included in the base rates is permitted to be billed or is required to be
credited to  customers.  Each month,  the  difference  between  actual  costs of
purchased gas and gas costs  recovered from customers is deferred.  The deferred
differences are billed or credited,  as appropriate,  to customers in subsequent
months.

Markets and Customers
         The  utility  continues  to  capitalize  on the healthy  economies  and
sustained  customer  growth found in its service  territory.  AWG and Associated
provide natural gas to approximately 119,000 residential, 16,300 commercial, and
225 industrial  customers,  while also providing gas transportation  services to
approximately 40 end-use and off-system customers.  Total gas throughput in 2000
was 33.5 Bcf,  compared to 36.4 Bcf in 1999 and 32.8 Bcf in 1998.  In 2000,  the
loss of throughput associated with the sale of the utility's Missouri assets was
partially  offset by colder  weather.  The  increase  in 1999 was the  result of
higher off-system transportation volumes. Off-system transportation volumes were
3.1 Bcf in 2000, compared to 4.8 Bcf in 1999 and 1.1 Bcf transported in 1998.

         Residential and Commercial. Approximately 85% of the utility's revenues
are  from  residential  and  commercial  markets.   Residential  and  commercial
customers  combined  accounted  for  55% of  total  gas  throughput  for the gas
distribution  segment  in 2000,  compared  to 51% in 1999  and 57% in 1998.  Gas
volumes sold to residential  customers  were 10.9 Bcf in 2000,  compared to 10.8
Bcf in 1999 and 11.1 Bcf in 1998. Gas sold to commercial  customers  totaled 7.6
Bcf in 2000, 1999 and 1998.  Weather during the calendar year 2000 was normal as
measured by degree days,  however,  deliveries were  negatively  impacted by the
sale of the  Company's  Missouri  properties.  The decrease in  residential  gas
volumes sold in 1999 was due to record warm weather. Weather during 1999 was 21%
warmer than normal and 8% warmer than in 1998.

         The gas heating load is one of the most significant uses of natural gas
and is sensitive to outside temperatures.  Sales, therefore, vary throughout the
year.  Profits,   however,   have  become  less  sensitive  to  fluctuations  in
temperature  recently  as  tariffs  implemented  in  Arkansas  contain a weather
normalization  clause to lessen the impact of revenue  increases  and  decreases
which might result from weather variations during the winter heating season.

         Industrial  and  End-use   Transportation.   Deliveries  to  industrial
customers,  which are generally  smaller concerns using gas for plant heating or
product  processing,  accounted for 11.8 Bcf in gas deliveries in 2000, 13.1 Bcf
in 1999 and 13.0 Bcf in 1998. No industrial  customer  accounts for more than 8%
of Arkansas  Western's total  throughput.  The decline in deliveries in 2000 was
primarily the result of the sale of the utility's Missouri operations.

         Both AWG and  Associated  offer a  transportation  service  that allows
larger business  customers to obtain their own gas supplies  directly from other
suppliers.  A total of 39  customers  are  currently  using  the  transportation
service,  including  AWG's  17  largest  customers  in  northwest  Arkansas  and
Associated's 3 largest customers in northeast Arkansas.

                                       12

Competition
         AWG and  Associated  have  experienced  a general trend in recent years
toward  lower  rates of usage  among  their  customers,  largely  as a result of
conservation  efforts that the Company  encourages.  Competition is increasingly
being experienced from alternative fuels, primarily  electricity,  fuel oil, and
propane.  A  significant  amount  of fuel  switching  has not been  experienced,
though,  as natural gas has  generally  been the least  expensive,  most readily
available  fuel in the service  territories  of AWG and  Associated.  This could
change,  however, if natural gas prices continue to remain at their current high
levels.

         The  competition  from  alternative  fuels and, in a limited  number of
cases,  alternative  sources of natural gas have  intensified  in recent  years.
Industrial   customers  are  most  likely  to  consider   utilization  of  these
alternatives,  as they are less readily  available to commercial and residential
customers.  In an effort  to  provide  some  pricing  alternatives  to its large
industrial customers with relatively stable loads, AWG offers an optional tariff
to its larger business  customers and to any other large business customer which
shows that it has an  alternate  source of fuel at a lower  price or that one of
its direct  competitors has access to cheaper  sources of energy.  This optional
tariff  enables those  customers  willing to accept the risk of price and supply
volatility  to  direct  AWG  to  obtain  a  certain   percentage  of  their  gas
requirements  in the spot market.  Participating  customers  continue to pay the
non-gas  cost of service  included in AWG's  present  tariff for large  business
customers and agree to reimburse  AWG for any  take-or-pay  liability  caused by
spot market purchases on the customer's behalf.

Regulation
         The Company's  utility rates and  operations are regulated by the APSC.
The Company  operates through  municipal  franchises that are perpetual by state
law. These franchises, however, are not exclusive within a geographic area.

         As the  regulatory  focus of the natural gas  industry  shifts from the
federal level to the state level, utilities across the nation are being required
to unbundle  their sales services from  transportation  services in an effort to
promote  greater  competition.   Although  no  such  legislation  or  regulatory
directives related to natural gas are presently pending in Arkansas, the Company
is aggressively controlling costs and constantly reviewing issues such as system
capacity  and  reliability,  obligation  to serve,  rate design and  stranded or
transition costs.

         In Arkansas, the state legislature is now considering  legislation that
would  deregulate the retail sale of electricity in Arkansas as soon as 2002. At
this time, it is unknown whether or not such  legislation  will be adopted or if
it is  adopted,  what its final  form will be.  The  Company  is also  unable to
predict the precise impact of any such  legislation  on its utility  operations.
The Company's utility subsidiary has historically maintained a substantial price
advantage over electricity for most applications.  However, if gas prices are at
high levels or if retail electric competition is implemented in Arkansas,  it is
possible that some portion of this price  advantage may be lost in some markets.
As described in the paragraph above, the Company is taking steps to preserve its
competitive advantage over alternative energy sources, including electricity. If
electric  deregulation occurs in Arkansas,  legislative or regulatory precedents
may be set that would also affect  natural gas  utilities  in the future.  These
issues may include further  unbundling of services and the regulatory  treatment
of stranded costs.

         Gas distribution  revenues in future years will be impacted by customer
growth  and rate  increases  allowed  by the  APSC.  In  recent  years,  AWG has
experienced customer growth of approximately 2% to 3% annually, while Associated
has experienced  customer growth of approximately 1% or less annually.  Based on
current economic  conditions in the Company's service  territories,  the Company
expects this trend in customer growth to continue.

                                       13

         In  December  1996,  AWG  received  approval  from  the APSC for a rate
increase of $5.1 million annually.  The December 1996 rate increase order issued
by the  APSC  also  provided  that  AWG  cause  to be  filed  with  the  APSC an
independent  study of its procedures for allocating costs between  regulated and
non-regulated  operations,  its staffing levels and executive compensation.  The
independent study was ordered by the APSC to address issues raised by the Office
of the  Attorney  General of the State of Arkansas.  The study was  conducted in
1999 with a final report issued in December 1999. The report found the Company's
costs to be  reasonable in all  categories  and did not recommend any changes in
rates currently in effect.

         The Company  received  approvals in December 1997 from the APSC and the
Missouri  Public  Service  Commission  for rate increases and tariff changes for
Associated  which  allowed the  utility to collect an  additional  $3.0  million
annually.  Of the $3.0 million increase,  approximately  $2.0 million was in the
form of base rate  increases and $1.0 million was related to the increased  cost
of service of the Company's  gathering  plant which is recovered  through either
the purchased gas adjustment  clause or through direct charges to transportation
customers. Rate increase requests that may be filed in the future will depend on
customer growth,  increases in operating expenses, and additional investments in
property,  plant and  equipment.  AWG's  rates for gas  delivered  to its retail
customers are not regulated by the Federal Energy Regulatory  Commission (FERC),
but its  transmission  and gathering  pipeline systems are subject to the FERC's
regulations  concerning open access  transportation since AWG accepted a blanket
transportation certificate in connection with its merger with Associated.

         In May 1999,  the Staff of the APSC  initiated a proceeding in which it
sought  an annual  reduction  of  approximately  $2.3  million  in the rates AWG
charges its  customers  in  northwest  Arkansas.  Staff's  position was based on
various  adjustments to the utility's  rate base,  operating  expenses,  capital
structure  and rate of return.  A large  portion of the proposed  reduction  was
based on a  downward  adjustment  to the  utility's  current  return  on  equity
authorized by the APSC in 1996.  During the third  quarter of 1999,  the Company
reached agreement with the Staff and the APSC to resolve this issue and to close
several other open dockets. In the settlement  agreement,  the Company agreed to
reduce its rates  collected from customers on a prospective  basis in the amount
of $1.4  million  annually,  effective  December  1, 1999.  The  agreement  also
includes the resolution of a proceeding  initiated in December 1998 by the Staff
of the APSC where the Staff had  recommended the  disallowance of  approximately
$3.1 million of gas supply costs. As a part of the  settlement,  this docket was
closed with no negative adjustment to the Company.

         In  February  2001,  the APSC  approved  a 90-day  temporary  tariff to
collect  additional  gas costs not yet billed to  customers  through  the normal
purchased gas adjustment clause in the utility's  approved tariffs.  The Company
had  under-recovered  purchased gas costs of $12.9 million in its current assets
at December  31, 2000.  The amount of  under-recovered  purchased  gas costs had
increased  to over  $30.0  million  during  January  2001 as a result of rapidly
increasing gas costs.  The temporary tariff allows the Company to bill customers
an additional  $3.00 per Mcf of usage and is expected to generate $14.0 to $15.0
million of  additional  cash flow over the next few months  allowing the Company
faster recovery of gas costs already incurred.

MARKETING AND TRANSPORTATION

Gas Marketing
         The marketing group was formed in mid-1996 to better enable the Company
to  capture   downstream   opportunities   which  arise  through  marketing  and
transportation  activity.  Through utilization of Southwestern's  existing asset
base, the group's focus is to create and capture value beyond the wellhead.  The
merger of the NOARK Pipeline with the Ozark Gas  Transmission  System  discussed
below afforded greater supply and market opportunities.

                                       14

         The   Company's   marketing   operations   include  the   marketing  of
Southwestern's own gas production and third-party  natural gas. Operating income
for this segment was $2.5 million in 2000,  compared to $2.1 million in 1999 and
$1.8  million in 1998.  The  segment  marketed  59.6 Bcf of natural gas in 2000,
compared  to 63.1  Bcf in 1999  and  49.6  Bcf in  1998.  Of the  total  volumes
marketed,  purchases from the Company's exploration and production  subsidiaries
accounted for 33% in 2000, 31% in 1999 and 24% in 1998.

NOARK Partnership
         At  December  31,  2000,  the Company  held a 25%  general  partnership
interest  in the NOARK  Pipeline  System,  Limited  Partnership  (NOARK).  NOARK
Pipeline was a 258-mile long  intrastate  natural gas  transmission  system that
originated in western  Arkansas and terminated in northeast  Arkansas,  crossing
three  major  interstate   pipelines  and  interconnecting  with  the  Company's
distribution systems. NOARK Pipeline was completed and placed in service in 1992
and has been operating below capacity and generating  losses since it was placed
in service.  The Company's share of the pretax loss from  operations  related to
its NOARK  investment  was $1.8  million in 2000,  $2.0 million in 1999 and $3.1
million in 1998.

         In January 1998, the Company entered into an agreement with Enogex Inc.
(Enogex), a subsidiary of OGE Energy Corp., to expand NOARK Pipeline and provide
access to Oklahoma gas supplies  through an  integration  of NOARK Pipeline with
the Ozark Gas  Transmission  System  (Ozark).  Ozark was a  437-mile  interstate
pipeline  system  that  began in  eastern  Oklahoma  and  terminated  in eastern
Arkansas.  On July 1, 1998,  the Federal  Energy  Regulatory  Commission  (FERC)
authorized  the  operation  and  integration  of Ozark and NOARK  Pipeline  as a
single,  integrated  pipeline.  The FERC order also  authorized  the purchase of
Ozark by a subsidiary of Enogex and the construction of integration  facilities.
Enogex  acquired  Ozark  and  contributed  the  pipeline  system  to  the  NOARK
partnership  and also  acquired  the  NOARK  partnership  interests  not held by
Southwestern.  Enogex  funded the  acquisition  of Ozark and the  expansion  and
integration with NOARK Pipeline which resulted in the Company's  interest in the
partnership decreasing to 25% with Enogex owning a 75% interest.  There are also
provisions  in  the  agreement  with  Enogex  which  allow  for  future  revenue
allocations to the Company above its 25% partnership interest if certain minimum
throughput and revenue assumptions are not met.

         The  merged  pipeline  system  now has  greater  access  to  major  gas
producing  fields in  Oklahoma.  With  access to  greater  regional  production,
Southwestern  expects  the  pipeline's   additional  throughput  to  create  new
marketing and transportation  opportunities and reduce the losses experienced on
the project in the past. The merged pipeline also provides the Company's utility
systems with additional access to gas supply.

         The new integrated system, known as Ozark Pipeline,  became operational
November 1, 1998,  and  includes 749 miles of pipeline  with a total  throughput
capacity of 330 MMcfd.  Deliveries  are currently  being made by the pipeline to
portions of AWG's  distribution  system,  to  Associated,  and to the interstate
pipelines  with which it  interconnects.  The average daily  throughput  for the
pipeline  was 188.2 MMcfd in 2000,  compared to 167.5 MMcfd in 1999.  Before the
integration  with Ozark,  NOARK Pipeline had an average daily throughput of 27.3
MMcfd in 1998. At December 31, 2000, AWG had transportation contracts with Ozark
Pipeline for 66.9 MMcfd of firm  capacity.  These  contracts  expire in 2002 and
2003 and are  renewable  annually  thereafter  until  terminated  with 180 days'
notice.

Competition
         The Company's gas marketing activities are in competition with numerous
other  companies  offering  the  same  services,  many of which  possess  larger
financial  and  other  resources  than  those  of  Southwestern.  Some of  these
competitors are affiliates of companies with extensive pipeline systems that are
used for  transportation  from producers to end-users.  Other factors  affecting
competition are cost and  availability of alternative  fuels,  level of consumer
demand,  and  cost  of and

                                       15

proximity of pipelines and other transportation facilities. The Company believes
that its ability to  effectively  compete  within the  marketing  segment in the
future depends upon  establishing  and  maintaining  strong  relationships  with
producers and end-users.

         NOARK Pipeline previously competed with two interstate  pipelines,  one
of which was the Ozark  system,  to obtain gas  supplies for  transportation  to
other markets.  Because of the available transportation capacity in the Arkansas
portion of the Arkoma  Basin,  competition  had been strong and had  resulted in
NOARK Pipeline  transporting gas for third parties on an interruptible  basis at
rates well below the maximum tariffs  presently  allowed.  The integration  with
Ozark provides increased supplies to transport to both local markets and markets
served by the three major interstate pipelines that Ozark Pipeline connects with
in eastern Arkansas. As discussed below under "Regulation," FERC's Order No. 636
has generally increased  competition in the transportation  segment as end-users
are now  acquiring  their  own  supplies  and  independently  arranging  for the
transportation of those supplies.  The Company believes that Ozark Pipeline will
provide the additional  supplies  necessary to compete more  effectively for the
transportation  of natural gas to end-users and markets served by the interstate
pipelines.

Regulation
         Since  the  mid-1980's,  the  FERC  has  issued  a  series  of  orders,
culminating in Order No. 636 in April 1992,  that have altered the marketing and
transportation  of natural gas.  Order No. 636 required  interstate  natural gas
pipelines to "unbundle," or segregate,  the sales,  transportation,  storage and
other  components of their existing sales services,  and to separately state the
rates for each of the  unbundled  services.  Order No. 636 and  subsequent  FERC
orders  issued in  individual  pipeline  proceedings  have been the  subject  of
appeals,  the results of which have generally been supportive of the FERC's open
access policy. Generally,  Order No. 636 has eliminated or substantially reduced
the  interstate   pipelines'   role  as  wholesalers  of  natural  gas  and  has
substantially increased competition in natural gas markets.

         Prior to the integration  with Ozark,  the operations of NOARK Pipeline
were  regulated by the APSC. The APSC had  established a maximum  transportation
rate of  approximately  $.285 per dekatherm.  The  integration of NOARK Pipeline
with Ozark resulted in an interstate pipeline system subject to FERC regulations
and FERC  approved  tariffs.  The APSC no longer  has  jurisdiction  over  NOARK
Pipeline's transportation rates and services. The FERC initially set the maximum
transportation rate of Ozark Pipeline at $.2455 per dekatherm.  As the result of
a rate  case  filed  in  2000,  Ozark  Pipeline's  maximum  transportation  rate
increased to $.2867 per dekatherm,  effective November 1, 2000. Also as a result
of the rate case,  Ozark Pipeline plans to begin offering  no-notice  service to
its customers in September 2001.

OTHER ITEMS

Environmental Matters
         The Company's  operations are subject to extensive  federal,  state and
local laws and regulations,  including the Comprehensive Environmental Response,
Compensation  and  Liability  Act,  the Clean  Water Act,  the Clean Air Act and
similar state statutes.  These laws and regulations require permits for drilling
wells and the  maintenance of bonding  requirements in order to drill or operate
wells and also  regulate  the  spacing  and  location  of wells,  the  method of
drilling and casing wells,  the surface use and  restoration of properties  upon
which wells are drilled,  the plugging and  abandoning of wells,  the prevention
and cleanup of pollutants and other matters.  Southwestern  maintains  insurance
against costs of clean-up operations,  but is not fully insured against all such
risks.

         Compliance with  environmental laws and regulations has had no material
effect  on  Southwestern's   capital  expenditures,   earnings,  or  competitive
position.  Although future environmental  obligations are not expected to have a
material  impact on the results of  operations  or  financial  condition  of the
Company,   there  can  be  no  assurance  that

                                       16

future  developments,  such  as  increasingly  stringent  environmental  laws or
enforcement thereof, will not cause the Company to incur material  environmental
liabilities or costs.

Real Estate Development
         A. W. Realty Company (AWR) owns an interest in approximately  150 acres
of real  estate,  most of which is  undeveloped.  AWR's real estate  development
activities  are  concentrated  on a 130-acre  tract of land located in northwest
Arkansas,  which is the seventh fastest growing  metropolitan area in the United
States.  The Company  has owned an  interest  in this land for many  years.  The
property  is  zoned  for  commercial,   office,  and  multi-family   residential
development.  AWR  continues  to review  with a joint  venture  partner  various
options for developing  this property that would minimize the Company's  initial
capital  expenditures,  but  still  enable  it to  retain  an  interest  in  any
appreciation in value. This activity,  however, does not represent a significant
portion of the Company's business.

Employees
         At December 31,  2000,  the Company had 536  employees,  31 of whom are
represented under a collective bargaining  agreement.  The Company believes that
its relations with its employees are good.

         During 2000,  Southwestern was required to file Form 23, "Annual Survey
of Domestic Oil and Gas Reserves" with the  Department of Energy.  The basis for
reporting  reserves on Form 23 is not comparable to the reserve data included in
Note 6 to the financial  statements  in the 2000 Annual Report to  Shareholders.
The primary  differences are that Form 23 reports gross reserves,  including the
royalty owners' share, and includes reserves for only those properties where the
Company is the operator.

ITEM 3. LEGAL PROCEEDINGS

         In its Form 8-K  filed  July 2,  1996,  the  Company  disclosed  that a
lawsuit relating to overriding royalty interests in certain Arkansas oil and gas
properties had been filed against it and two of its  wholly-owned  subsidiaries.
This matter went to a non-jury  trial as to liability  on January 10, 2000.  The
court in this matter issued  Findings of Fact and  Conclusions of Law that found
no fraud was committed. The court also found that any override royalty interests
that  might  ultimately  be found to be due  under  the  plaintiffs'  claim  for
additional  override  royalties accrued after

                                       18

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  proceeding  that is scheduled for April 30, 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 United States Minerals  Management  Service (MMS), a federal agency
responsible  for  the   administration   of  federal  oil  and  gas  leases,  is
investigating  the Company and its  subsidiaries in respect of claims similar to
those in the Hales class action  royalty  litigation  previously  reported.  The
Company was found to be ultimately  liable and  satisfied the Hales  judgment in
July  2000.  MMS  was  included  in the  class  action  litigation  against  its
objections, but did not pursue further action to remove itself from the class.

         On August 25, 2000,  a class action suit was filed  against the Company
and its  subsidiaries in Sebastian  County,  Arkansas,  on behalf of all mineral
owners who own or owned a royalty and/or overriding  royalty interest in oil and
gas leases or other agreements in certain sections of Franklin County, Arkansas.
The Company was granted authority in 1968 by the Arkansas Oil and Gas Commission
to operate a gas storage facility in one section of Franklin County.  Based upon
subsequently  developed  geological data, the Company sought authority to expand
this area and was granted  authority by the Arkansas Oil and Gas  Commission  to
operate gas storage in  additional  sections.  Plaintiffs  are  challenging  the
storage agreements that the Company obtained from the mineral interest owners in
1968,  1999 and 2000 to operate the gas storage  facility  known as  "Stockton."
Plaintiffs allege various wrongful,  intentional and fraudulent acts relating to
the  operation  of the storage  pool  beginning  in 1968 and  continuing  to the
present and allege that the above-referenced  agreements from the mineral owners
were obtained  through  misrepresentation  and fraud.  The Company has owned and
operated  the Stockton  storage  unit  through its Arkansas  Western Gas Company
subsidiary  until  1994,  at which time it was  transferred  to its  subsidiary,
SEECO,  Inc.  Plaintiffs  claim ownership rights in the gas that the Company has
stored in the  storage  pool in an amount  in  excess  of $5  million  in actual
damages,  interest,  attorney's fees and punitive  damages.  The Company and its
outside  counsel believe that this action is without merit and does not meet the
requirements  for a class action.  The Company believes that plaintiffs claim to
the storage gas, which the Company has injected into the storage  facility,  has
no merit and is not  supported by the Arkansas gas storage  statute  under which
the  Company  operates  this  facility.  While the amount of this claim could be
significant,  management believes, based upon its investigation, that this claim
is without merit and that the Company's ultimate liability,  if any, will not be
material to its consolidated  financial position, but in any one period it could
be significant to its results of operations.

         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 non-capital  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.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted  during the fourth quarter of the fiscal year
ended December 31, 2000, to a vote of security holders, through the solicitation
of proxies or otherwise.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS
OF OPERATIONS

         The  following  information  should  be read in  conjunction  with  the
information contained in the financial statements and the notes thereto included
in Item 8. of this  report  and with the  discussion  below on  "Forward-Looking
Information."  Certain  reclassifications  have been  made to the  prior  years'
financial   statements   to   conform   with   the  2000   presentation.   These
reclassifications had no effect on previously reported net income.

RESULTS OF OPERATIONS
         The Company  reported a net loss of $46.7 million,  or $1.86 per share,
for 2000,  compared to net income of $9.9 million,  or $.40 per share,  for 1999
and a net loss of $30.6 million,  or $1.23 per share, in 1998. The loss for 2000
includes one-time charges for unusual items, including a $109.3 million judgment
in the Hales  lawsuit (see Note 1 to the  financial  statements  for  additional
discussion) and a $2.0 million accrual for on-going litigation, an extraordinary
loss on the early  retirement of debt,  and a $3.2 million gain from the sale of
the Company's Missouri utility  properties.  Exclusive of these one-time charges
and the gain on sale, net income for 2000 would have been $20.5 million, or $.82
per  share.  The loss for 1998  reflects  the impact of an  after-tax,  non-cash
ceiling  test  write-down  of the  Company's  oil and gas  properties  of  $40.5
million,  or $1.63 per share.  Excluding the non-cash charge,  the Company would
have recognized net income of $9.9 million, or $.40 per share in 1998.

         Results for 2000, exclusive of the one-time charges and the gain on the
sale of the utility  properties,  reflect both  increased oil and gas production
and higher oil and gas prices  realized,  offset by higher operating and general
expenses and higher depreciation,  depletion and amortization  expense.  Results
for 1999 and 1998 were  negatively  impacted  by lower  wellhead  prices for the
Company's oil and gas production and by unseasonably warm weather.

Exploration and Production
         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.

                                       24

Revenues and Operating Income
         The Company's exploration and production revenues increased 48% in 2000
and  decreased  13% in 1999.  The  increase  in 2000 was due to an  increase  in
production and higher average prices received. The decrease in 1999 revenues was
due to lower  volumes  of oil and gas  produced  and a lower  average  gas price
received.

         Operating  income of the exploration  and production  segment was $40.7
million in 2000 excluding the impact of the Hales judgment and the other unusual
items,  compared to $16.5 million in 1999,  and $19.1 million in 1998  excluding
the impact of the non-cash write-down of oil and gas properties. The increase in
2000 was due to an 8% increase in equivalent  oil and gas  production and higher
oil and gas prices realized,  partially offset by increased  operating costs and
expenses.  The  decrease  in  1999  was  due  primarily  to an 11%  decrease  in
equivalent oil and gas production volumes.

Production
         Gas and oil  production  totaled  35.7  billion  cubic feet  equivalent
(Bcfe) in 2000,  32.9 Bcfe in 1999 and 36.9 Bcfe in 1998.  The  increase in 2000
production  volumes  resulted  from  new  wells  added  in 2000  and 1999 in the
Company's Permian Basin and south Louisiana operating areas, partially offset by
the  loss of  production  from  certain  wells  in the  Company's  Mid-Continent
operating  area that were sold at auction  during  2000.  The  decrease  in 1999
production  was  due to the  combined  effects  of  production  declines  in the
Company's outside operated properties  resulting from the industry slowdown that
began  in  1998,  production  declines  in  some  of the  Company's  Gulf  Coast
properties,  and the loss of production from marginal  properties that were sold
in 1999.

         Gas sales to  unaffiliated  purchasers  were 23.8 Bcf in 2000,  up from
21.2 Bcf in 1999 and 21.4 Bcf in  1998.  Sales to  unaffiliated  purchasers  are
primarily made under contracts which reflect current short-term prices and which
are subject to seasonal price swings.

         Intersegment  sales to Arkansas  Western Gas Company (AWG), the utility
subsidiary which operates the Company's  northwest Arkansas utility system, were
5.1 Bcf in both 2000 and 1999 and 7.7 Bcf in 1998.  Although weather as measured
in degree days was normal in 2000 and colder  than 1999,  sales to AWG were flat
as record cold weather in the months of November and December caused the Company
to  utilize  its  storage  facilities  in  addition  to gas  production  to meet
contractual  commitments  to AWG.  Affiliated  deliveries  for 1999 were down as
unseasonably  warm weather  decreased AWG's demand for the Company's gas supply.
The Company's gas production provided approximately 36% of AWG's requirements in
2000, 38% in 1999 and 55% in 1998.

         Prior to 1999,  most of the sales to AWG's  system were  pursuant to an
intersegment  long-term  contract entered into in 1978 with SEECO, Inc. (SEECO).
In October 1998, AWG instituted a competitive bidding process for its gas supply
that included seven different packages.  These bid requests included replacement
of the gas supply and no-notice service previously provided by the long-term gas
supply contract  between AWG and SEECO.  In the initial 1998 bid,  SEECO,  along
with the Company's marketing  subsidiary,  successfully bid on five of the seven
packages with prices based on the NorAm East Index plus a demand  charge.  Based
on normal  weather  patterns,  the volumes of gas projected to be supplied under
these contracts would be  approximately  equal to the historical  annual volumes
sold under the expired long-term contract. However, under the new contracts, the
Company  supplied most of AWG's  no-notice  service and less of its routine base
requirements than it had under the previous  contract.  During periods of warmer
weather,  as in early 2000 and in 1999 and 1998, lower total gas volumes will be
sold to AWG than  compared  to  periods of normal or colder  weather.  The total
premium  over the NorAm East Index  under these  contracts  is  estimated  to be
approximately  $1.0 million lower  (after-tax)  than the annual  premium  earned
under the expired  long-term  contract.  The majority of the premium is received
through monthly demand charges which are received regardless of volumes actually
delivered.  Other sales to AWG are made under long-term  contracts with flexible
pricing provisions.

                                       25

         Of the five bid packages originally secured by the Company,  three were
for a 3-year term,  one was for a 2-year term and one was for a 1-year term. The
Company  was  unsuccessful  in  subsequent  bidding  for the  2-year  and 1-year
packages and no longer makes affiliated sales under those contracts.  There were
no demand  fees  associated  with these two bid  packages.  In total,  these two
packages  provided  approximately  2.5 Bcf  annually  of AWG's gas  supply.  Gas
volumes previously sold at market prices to AWG under these two packages are now
sold to unaffiliated parties. The three remaining packages will again be put out
to bid by AWG in 2001. The Company will bid to retain 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.

         The  Company's  intersegment  sales to  Associated  Natural Gas Company
(Associated),  a  division  of AWG which  operates  the  Company's  natural  gas
distribution  system in  northeast  Arkansas,  were 2.7 Bcf in 2000,  3.1 Bcf in
1999, and 3.6 Bcf in 1998. Affiliated deliveries to Associated decreased in 2000
due to the  sale  of  Associated's  Missouri  utility  operations  in May  2000.
Deliveries  to  Associated  decreased  in 1999 due  primarily  to  corresponding
changes in  heating  weather.  Effective  October  1990,  SEECO  entered  into a
ten-year contract with Associated to supply a portion of its system requirements
at a price  to be  redetermined  annually.  For the  contract  period  beginning
October 1, 1997, the contract was revised to redetermine the sales price monthly
based on an index  posting  plus a  reservation  fee.  Effective  October  2000,
Associated  placed its gas supply out for  competitive  bids.  The  Company  was
successful in obtaining a one-year bid to supply  approximately  1.0 Bcf of gas,
or approximately 40% of Associated's annual requirement  assuming normal weather
patterns.

         The Company  expects  future  increases in its gas  production  to come
primarily  from  sales to  unaffiliated  purchasers.  The  Company  is unable to
predict  changes  in the  market  demand and price for  natural  gas,  including
changes  which  may be  induced  by the  effects  of  weather  on demand of both
affiliated   and   unaffiliated   customers   for  the   Company's   production.
Additionally,  the Company holds a large amount of undeveloped leasehold acreage
and producing  acreage,  and has an inventory of drilling  leads,  prospects and
seismic data that will continue to be evaluated and developed in the future. The
Company's  exploration  programs have been directed primarily toward natural gas
in recent years.

Commodity Prices
         The overall average price realized for the Company's gas production was
$2.88  per Mcf in 2000,  $2.21 per Mcf in 1999,  and $2.34 per Mcf in 1998.  The
changes in the average  price  realized  primarily  reflects  changes in average
annual  spot  market  prices and the  effects  of the  Company's  price  hedging
activities. The Company's hedging activities lowered the average gas price $1.04
per Mcf in 2000 and $.06 per Mcf in 1999,  and added $.19 per Mcf to the average
gas price in 1998.  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.

         The Company  realized an average price of $22.99 per barrel for its oil
production  for the year ended  December 31, 2000, up from $17.11 per barrel for
1999 and $13.60 per barrel for 1998.

         The Company periodically enters into hedging activities with respect to
a portion  of its  projected  crude oil and  natural  gas  production  through a
variety of  financial  arrangements  intended  to support  oil and gas prices at
targeted levels and to minimize the impact of price  fluctuations (see Note 8 of
the financial  statements for  additional  discussion).  The Company's  policies
prohibit   speculation   with   derivatives   and  limit  swap   agreements   to
counterparties  with  appropriate  credit  standings.  At December 31, 2000, the
Company  had hedges in place on 34.7 Bcf of future gas  production  and  697,000
barrels of future oil  production.  Subsequent to December 31, 2000, the Company
closed its position on 298,000 barrels with a floor price of $18.00. The Company
currently has hedged  approximately  80% of its 2001  anticipated gas production
levels and 50% of its projected oil production.

                                       26

         Disregarding  the impact of hedges,  the  Company  expects  the average
price it  receives  for its total gas  production  to be  slightly  higher  than
average  spot market  prices due to the prices it receives  under the  contracts
covering its  intersegment  sales which provide swing  services to the Company's
utility  systems.  Future  changes in revenues  from sales of the  Company's gas
production will be dependent upon changes in the market price for gas, access to
new markets, maintenance of existing markets, and additions of new gas reserves.

Operating Costs and Expenses
         Production  expenses  per  Mcfe  for this  segment  were  $.40 in 2000,
compared to $.35 in 1999 and $.34 in 1998.  Production  taxes per Mcfe were $.15
in 2000  compared  to $.09 in both 1999 and 1998.  The  increase  in  production
expenses per Mcfe in 2000 was due primarily to an increase in workover expenses.
The increase in 2000  production  taxes per Mcfe was due to increased  severance
and ad valorem  taxes that resulted from higher  commodity  prices.  General and
administrative  expense per Mcfe was $.32 in 2000,  compared to $.30 in 1999 and
$.34 in 1998.  The  increase  in  general  and  administrative  costs in 2000 as
compared to 1999 resulted from increases in incentive  compensation  pay that is
dependent  upon the  operating  results for this  segment.  The decrease in 1999
general and  administrative  costs as compared to 1998 resulted  from  severance
costs and other costs  related to the  closing of the  Company's  Oklahoma  City
office in 1998.

         The Company's full cost pool  amortization rate averaged $1.06 per Mcfe
for 2000,  compared  to $1.00  per Mcfe in 1999 and $1.04 per Mcfe in 1998.  The
average rate  increased in 2000 due  primarily to a $9.9 million  decline in the
balance of unevaluated  costs excluded from  amortization in the full cost pool.
The rate  decreased  in 1999 as  compared  to 1998 due to the full cost  ceiling
write-down taken in 1998.

         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
(standardized  measure)  plus the  lower  of cost or  market  value of  unproved
properties.  At December 31, 2000, 1999 and 1998 the Company's unamortized costs
of oil and gas properties did not exceed this ceiling  amount.  Primarily due to
high oil and gas  prices in  effect  at  year-end,  the  Company's  standardized
measure  increased to $895.1  million at December  31, 2000,  compared to $262.1
million at December 31, 1999 and $222.8  million at December  31,  1998.  Market
prices for natural gas have declined since December 31, 2000,  although they are
still considerably  higher than prices in effect at year-end 1999 and 1998. As a
comparative  measure only,  the Company's  standardized  measure at December 31,
2000,  assuming a NYMEX  index  price of $4.50 per Mcf and a WTI index  price of
$25.00 per barrel,  would have been  approximately  $487.0 million. A decline in
oil and gas prices from  year-end  2000 levels or other  factors,  without other
mitigating  circumstances,  could cause a future write-down of capitalized costs
and a noncash charge against future earnings.

         Inflation  impacts the Company by generally  increasing  its  operating
costs and the costs of its capital  additions.  The effects of  inflation on the
Company's  operations  in recent  years have been  minimal due to low  inflation
rates. However, during 2000 the impact of inflation intensified in certain areas
of the Company's  exploration  and  production  segment as shortages in drilling
rigs,  third party  services and  qualified  labor  developed  due to an overall
increase in the activity level of the domestic oil and gas industry. This impact
is  continuing  into 2001 with the  significant  increases in oil and gas prices
experienced  during the past  several  months.  Increased  competition  in south
Louisiana  has also had the impact of  increasing  3-D seismic and land costs in
the area.

                                       27

Gas Distribution
         The operating  results of the Company's  gas  distribution  segment are
highly  seasonal.  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  (APSC).  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.

         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  authorized  management to pursue the sale of the Company's  remaining
gas  distribution  operations.  The sale process did not result in an acceptable
bid.  Although the Company may 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
         Gas  distribution  revenues  fluctuate due to the  pass-through  of gas
supply  cost  changes  and  due  to  the  effects  of  weather.  Because  of the
corresponding  changes  in  purchased  gas  costs,  the  revenue  effect  of the
pass-through of gas cost changes has not materially affected net income.

         Gas  distribution  revenues  increased  14% in 2000 and decreased 2% in
1999.  The increase in 2000 was due to a higher sales rate and  increased  sales
volumes  caused  by colder  weather,  partially  offset by the loss of  revenues
resulting from the sale of the utility's  Missouri assets.  The decrease in 1999
was due to the  effects  of warmer  weather.  Weather in 2000 was normal and 26%
colder  than the prior  year.  Weather in 1999 was 21% warmer than normal and 8%
warmer than the prior year.

         Operating income for  Southwestern's  utility systems  decreased 15% in
2000 and  increased 7% in 1999.  The decrease in 2000  resulted from the sale of
the  Missouri  assets  and  a  $1.4  million  annual  rate  reduction  that  was
implemented  in December  1999.  The  increase in 1999 was due to the  Company's
efforts in reducing operating costs and to customer growth.

                                       28

Deliveries and Rates
         In 2000, AWG sold 16.8 Bcf to its customers at an average rate of $6.45
per Mcf, compared to 14.5 Bcf at $5.47 per Mcf in 1999 and 15.1 Bcf at $5.37 per
Mcf in 1998. Additionally, AWG transported 6.3 Bcf in 2000, 6.2 Bcf in 1999, and
6.0 Bcf in 1998  for  its  end-use  customers.  Associated  sold  5.3 Bcf to its
customers  in 2000 at an average  rate of $6.89 per Mcf,  compared to 7.4 Bcf in
1999  at  $6.06  per  Mcf and 7.8  Bcf at  $5.95  per  Mcf in  1998.  Associated
transported  2.0 Bcf for its end-use  customers in 2000,  compared to 3.4 Bcf in
1999  and 2.8 Bcf in  1998.  The  decrease  in the  combined  volumes  sold  and
transported for end-use customers in 2000 resulted from the sale of the Missouri
properties,  offset by increased deliveries due to colder weather, and decreased
in 1999  due to  warmer  weather,  partially  offset  by  customer  growth.  The
fluctuations  in the average sales rates reflect  changes in the average cost of
gas purchased for delivery to the Company's customers,  which are passed through
to customers under automatic adjustment clauses.

         Total  deliveries  to  industrial  customers  of  AWG  and  Associated,
including  transportation  volumes,  were 11.8 Bcf in 2000, 13.1 Bcf in 1999 and
13.0 Bcf in 1998.  The decline in  deliveries  in 2000 resulted from the sale of
the Missouri  assets.  AWG also transported 3.1 Bcf of gas through its gathering
system in 2000 for  off-system  deliveries,  all to the  Ozark Gas  Transmission
System, compared to 4.8 Bcf in 1999 and 1.1 Bcf in 1998. The level of off-system
deliveries each year generally  reflects the changes of on-system demands of the
Company's gas distribution systems for the Company's gas production. The average
off-system  transportation  rate was  approximately  $.10 per Mcf,  exclusive of
fuel, in 2000 and 1999, and $.11 per Mcf in 1998.

         Gas  distribution  revenues  in future  years will be  impacted  by the
utility's  gas  purchase  costs,  the  sale of the  Company's  Missouri  assets,
customer growth and rate increases allowed by the APSC. In recent years, AWG has
experienced customer growth of approximately 2% to 3% annually, while Associated
has experienced  customer growth of approximately 1% or less annually.  Based on
current economic  conditions in the Company's service  territories,  the Company
expects this trend in customer growth to continue.

         In  February  2001,  the APSC  approved  a 90-day  temporary  tariff to
collect  additional gas costs not yet billed to customers  through the utility's
normal purchased gas adjustment clause in its approved tariffs.  The Company had
under-recovered  purchased  gas  costs of $12.9  million  in  current  assets at
December 31, 2000.  The level of deferred  purchases had increased to over $30.0
million  during January 2001 as a result of rapidly  increasing  gas costs.  The
temporary  tariff allows the utility to bill  customers an additional  $3.00 per
Mcf of usage and is expected to generate  $14.0 to $15.0  million of  additional
cash flow during the next few months allowing the Company faster recovery of gas
costs already incurred.

         Tariffs  implemented  in Arkansas as a result of rate increases in both
1996 and 1997  contain a weather  normalization  clause to lessen  the impact of
revenue  increases  and  decreases  which might result from  weather  variations
during the winter heating season. Rate increase requests,  which may be filed in
the future, will depend on customer growth, increases in operating expenses, and
additional investment in property, plant and equipment. See "Regulatory Matters"
below for  additional  discussion  related  to the  Company's  gas  distribution
segment.

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  Missouri  assets as
discussed  above.  Other  operating  costs and expenses of the gas  distribution
segment for 2000 were lower than 1999 and 1998 due  primarily to the sale of the
utility's Missouri assets.

         Going forward, Southwestern's comparative operating results for its gas
distribution  segment will be lower  reflecting the Missouri asset  divestiture.
However,  the Company does not expect the sale to materially impact consolidated
earnings,  as the loss in  operating  income  should  generally  be  offset by a
corresponding decrease in corporate interest expense.

                                       29

         Inflation  impacts the Company's gas distribution  segment by generally
increasing  its  operating  costs and the costs of its  capital  additions.  The
effects of  inflation  on the  utility's  operations  in recent  years have been
minimal  due  to low  inflation  rates.  Additionally,  delays  inherent  in the
rate-making  process  prevent the Company from obtaining  immediate  recovery of
increased operating costs of its gas distribution segment.

Regulatory Matters
         In May 1999,  the Staff of the APSC  initiated a proceeding in which it
sought  an annual  reduction  of  approximately  $2.3  million  in the rates AWG
charges it customers in northwest  Arkansas.  The Staff's  position was based on
various  adjustments to the utility's  rate base,  operating  expenses,  capital
structure  and rate of return.  A large  portion of the proposed  reduction  was
based on a downward  adjustment to the utility's return on equity  authorized by
the APSC in  1996.  During  the  third  quarter  of 1999,  the  Company  reached
agreement with the Staff and the APSC to resolve this issue and to close several
other dockets that had remained open. In the settlement  agreement,  the Company
agreed to reduce its rates  collected from  customers on a prospective  basis in
the amount of $1.4 million annually,  effective  December 1, 1999. The agreement
also includes the  resolution of a proceeding  initiated in December 1998 by the
Staff of the APSC and that was  previously  disclosed  by the Company  where the
Staff had recommended  the  disallowance  of  approximately  $3.1 million of gas
supply costs. As part of the settlement, this docket was closed with no negative
adjustment to the Company.

         The Company  received  approvals in December 1997 from the APSC and the
Missouri Public Service  Commission (MPSC) for rate increases and tariff changes
which allow the utility to collect an additional $3.0 million  annually.  Of the
$3.0  million  total,  approximately  $2.0  million  is in the form of base rate
increases  and $1.0 million is related to the  increased  cost of service of the
Company's  gathering  plant which is recovered  through either the purchased gas
adjustment clause or through direct charges to transportation customers.

         In its order approving the Missouri  changes,  the MPSC further ordered
Associated to modify its purchased gas adjustment  tariff to remove any specific
language   referencing  recovery  of  the  cost  of  service  of  its  gathering
facilities.  The MPSC order  provided  that  Associated  should  base  gathering
charges to its customers on competitive  market  conditions and that it would be
allowed  recovery from its sales and  transportation  customers of all prudently
incurred  gathering  costs  without  reference to its cost of service.  The MPSC
reviews these gathering costs annually as part of its review of Associated's gas
costs.  Associated  believes that the MPSC lacks statutory  authority to approve
charges which are not based on historical cost of service.  Associated  appealed
this issue to the circuit  court  which ruled in favor of the MPSC.  The Company
appealed  the lower  court's  decision to the  Missouri  Court of Appeals  which
requested  that the MPSC  reissue  its  order  making  clear  the  basis for its
decision. The Company continued to bill its ratepayers gas gathering costs based
on its cost of  service  through  the date of the sale of its  Missouri  assets.
Gathering costs have been recovered in this manner from Missouri customers since
Associated's 1990 rate case. Prior to the 1997 changes,  Associated's  gathering
costs were recovered from Arkansas customers through its base rates.

         A December  1996 rate  increase  order issued by the APSC also provided
that AWG cause to be filed with the APSC an independent  study of its procedures
for  allocating  costs  between  regulated  and  non-regulated  operations,  its
staffing levels and executive compensation. The independent study was ordered by
the APSC to address  issues raised by the Office of the Attorney  General of the
State of Arkansas. The study was conducted in 1999 with a final report issued in
December  1999.  The report found the  Company's  costs to be  reasonable in all
categories and did not recommend any changes to the rates currently in effect.

         The Company is subject to continuing  reviews of it gas supply costs by
the APSC. The MPSC is currently auditing the last year of Associated's gas costs
in Missouri.  The Company currently has open issues with the MPSC, however,  the
Company  believes that none of these issues will have a material  adverse effect
on the Company's financial condition or results of operations.

                                       30

         AWG also purchases gas from  unaffiliated  producers under  take-or-pay
contracts.  The Company believes that it does not have a significant exposure to
liabilities resulting from these contracts and expects to be able to continue to
satisfactorily manage its exposure to take-or-pay liabilities.

         Operating income for the marketing segment was $2.5 million on revenues
of $207.7  million  in 2000,  compared  to $2.1  million on  revenues  of $137.5
million in 1999,  and $1.8  million on  revenues of $97.2  million in 1998.  The
Company marketed 59.6 Bcf in 2000,  compared to 63.1 Bcf in 1999 and 49.6 Bcf in
1998.  The  Company  enters  into  hedging  activities  with  respect to its gas
marketing  activities to provide margin  protection (see Note 8 of the financial
statements for additional discussion).

NOARK Partnership
         The  marketing  segment also manages the  Company's 25% interest in the
NOARK Pipeline System,  Limited  Partnership  (NOARK).  The NOARK Pipeline was a
258-mile long intrastate gas  transmission  system that extended across northern
Arkansas, crossing three major interstate pipelines and interconnecting with the
Company's  distribution  systems.  The NOARK Pipeline had been  operating  below
capacity and generating losses since it was placed in service in September 1992.
The Company's share of the pretax loss from operations  included in other income
related to its NOARK  investment was $1.8 million in 2000, $2.0 million in 1999,
and  $3.1  million  in 1998.  The  improvements  in the  2000  and 1999  results
primarily  reflect the benefits of the  integration of the NOARK Pipeline System
with the Ozark Gas  Transmission  System  (Ozark).  The  integration  of the two
systems was completed in November, 1998.

         In January 1998, the Company entered into an agreement with Enogex Inc.
(Enogex),  a  subsidiary  of OGE Energy  Corp.,  to expand the NOARK  system and
provide  access to Oklahoma gas supplies  through an  integration  of NOARK with
Ozark.  Ozark was a 437-mile  interstate  pipeline system which began in eastern
Oklahoma and terminated in eastern  Arkansas.  Effective August 1, 1998,  Enogex
acquired Ozark and  contributed  the pipeline  system to the NOARK  partnership.
Enogex also acquired the NOARK  partnership  interests not held by Southwestern.
Enogex funded the  acquisition of Ozark and the expansion and  integration  with
NOARK, which resulted in the Company's interest in the partnership decreasing to
25% with  Enogex  owning  a 75%  interest.  There  are  also  provisions  in the
agreement with Enogex which allow for future revenue  allocations to the Company
above its 25%  partnership  interest if certain  minimum  throughput and revenue
assumptions are not met. As a result of the changes discussed above, the Company
believes  that it  will  be  able  to  continue  to  reduce  the  losses  it has
experienced  on the NOARK  project  and expects  its  investment  in NOARK to be
realized over the life of the system (see Note 7 of the financial statements for
additional discussion).

         Ozark Pipeline,  the new integrated system became operational  November
1, 1998, and includes 749 miles of pipeline with a total throughput  capacity of
330 MMcfd.  Deliveries are currently  being made by the  integrated  pipeline to
portions of AWG's  distribution  system,  to  Associated,  and to the interstate
pipelines  with which it  interconnects.  Ozark  Pipeline  had an average  daily
throughput  of 188  million  cubic  feet of gas per day  (MMcfd) in 2000 and 168
MMcfd in 1999.  In 1998,  NOARK had an average  daily  throughput  of 27.3 MMcfd
before the  integration  with  Ozark.  As a result of a rate case filed in 2000,
Ozark Pipeline's maximum transportation rate increased from $.2455 per dekatherm
to $.2867 per dekatherm  effective  November 1, 2000. At December 31, 2000,  the
Company's gas distribution  subsidiary has  transportation  contracts with Ozark
Pipeline for 66.9 MMcfd of firm  capacity.  These  contracts  expire in 2002 and
2003 and are  renewable  annually  thereafter  until  terminated  with 180 days'
notice.

         As  further  explained  in Note  11 of the  financial  statements,  the
Company has severally guaranteed 60% of NOARK's currently outstanding debt. This
debt financed a portion of the original cost to construct the NOARK Pipeline.

Other Income, Costs and Expenses
         Interest costs,  net of  capitalization,  were up 34% in 2000 and 1% in
1999, both as compared to prior years. The increase in 2000 was caused primarily
by higher  average  borrowings  that resulted from payment of the Hales judgment
and to the current lower level of capitalized  interest related to the Company's
oil and gas properties.  Interest  capitalized  decreased 26% in 2000 and 15% in
1999. The changes in capitalized  interest are due primarily to decreases in the
level of costs  excluded from  amortization  in the  exploration  and production
segment.

         The  increase in other  income in 2000  resulted  from the $3.2 million
gain on the sale of the  Company's  Missouri gas  distribution  assets and gains
from the sale of other miscellaneous assets. The changes in other income in 1999
and 1998 relate  primarily to changes in the Company's share of operating losses
incurred  by  NOARK,  as  discussed  above.  Additionally,  in 1999 and 1998 the
Company  incurred  certain costs related to a judgment bond that the Company was
required to post after receiving the initial adverse verdict in the Hales case.

         The Hales judgment was the primary cause for the Company's deferred tax
benefit of $28.9 million in 2000. In 1998,  the  write-down of the Company's oil
and gas  properties  resulted  in a  deferred  tax  benefit  of  $25.9  million.
Excluding the impacts of these changes in deferred income taxes,  the changes in
the provisions  for current and deferred  income taxes recorded each year result
primarily from the level of taxable  income,  the collection of  under-recovered
purchased gas costs,  abandoned  property costs, and 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.

LIQUIDITY AND CAPITAL RESOURCES
         The Company  depends on  internally  generated  funds and its revolving
line of credit  discussed under  Financing  Requirements as its major sources of
liquidity.  Due to the Hales judgment and the impact of high year-end gas prices
on working capital,  net cash used in operating  activities was $53.2 million in
2000, compared to cash provided by operating activities of $58.1 million in 1999
and $93.7  million  in 1998.  The  primary  components  of cash  generated  from
operations are net income, depreciation, depletion and amortization,  write-down
of oil and gas  properties,  the provision for deferred income taxes and changes
in current assets and current  liabilities.  Net cash from operating  activities
provided  89%  of  the  Company's  capital   requirements  for  routine  capital
expenditures, cash dividends, and scheduled debt retirements in 1999 and 125% in
1998.

Capital Expenditures
         Capital  expenditures  totaled $75.7 million in 2000,  $67.0 million in
1999,  and $64.4  million in 1998.  The  Company's  exploration  and  production
segment expenditures  included  acquisitions of oil and gas producing properties
totaling  $6.7  million in 2000 and $9.4  million in 1999.  The Company  made no
producing property acquisitions in 1998.

         Capital investments planned for 2001 total $81.6 million, consisting of
$75.0 million for exploration and production,  $6.1 million for gas distribution
system  expenditures and $.5 million for general  purposes.  The Company expects
that its level of capital  investments  will be adequate to allow the Company to
maintain  its present  markets,  explore and  develop its  existing  gas and oil
properties as well as generate new drilling prospects,  and finance improvements
necessary due to normal customer growth in its gas distribution segment.

Financing Requirements
         At  year-end  2000,  Southwestern's  total  debt  was  $396.0  million,
including $171.0 million under a short-term  credit  facility.  This compares to
year-end 1999 total debt of $302.2 million, including $7.5 million classified as
short-term  debt.  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 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 and was 7.85% at December  31,  2000.  The new
credit  facility  has a term of 364 days and  expires in July 2001.  The Company
intends to renew or replace this facility prior to its expiration.

         In August 2000,  the Company  retired  $22.0  million of 9.36%  private
placement  notes.  Certain  costs  of  the  redemption  were  expensed  and  are
classified as an extraordinary loss, net of related income tax effects.

         In 1997, the Company issued $60.0 million of 7.625%  Medium-Term  Notes
due 2027 and $40.0 million of 7.21% Medium-Term Notes due 2017. These notes were
issued under a supplement to the  Company's  $250.0  million shelf  registration
statement  filed with the Securities  and Exchange  Commission in February 1997,
for the issuance of up to $125.0 million of Medium-Term  Notes.  The Company has
$25.0 million of capacity remaining under the shelf registration statement.  The
Company also has $125.0 million of 6.7% Notes due in 2005 that were issued under
the shelf registration. The Company's public notes are rated BBB by Standard and
Poor's and Baa3 by Moody's.

         In connection with the Enogex transaction in 1998 discussed above under
"NOARK  Partnership,"  the  Company  and a previous  general  partner  converted
certain of their loans to the NOARK  partnership,  plus accrued  interest,  into
equity, and contributed  approximately  $10.7 million to the partnership to fund
costs incurred in connection with the prepayment of NOARK's 9.74% Senior Secured
notes. The Company's share of the  contribution was $6.5 million.  In June 1998,
the NOARK  partnership  issued $80.0 million of 7.15% Notes due 2018.  The notes
require  semi-annual  principal  payments of $1.0 million that began in December
1998.  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%.  The Company  advanced  $3.3 million to
NOARK to fund its  share of debt  service  payments  in 2000 and  advanced  $2.3
million in 1999. If NOARK is unable to generate sufficient cash in the future to
service its debt and the Company is  required to continue  contributing  cash to
fund its debt  guarantee,  the  Company may be required to record the NOARK debt
commitment under current accounting rules.

         Under its short-term  credit  agreement the Company may not issue total
debt in excess of 80% of its total capital, shareholders' equity may not be less
than  $120.0  million  (excluding  any  adjustments  for SFAS No.  133 after its
adoption)  and the Company may not  declare or pay any  dividends  on its common
stock.  The Company must also have a ratio of earnings before  interest,  taxes,
depreciation  and  amortization  (EBITDA)  to fixed  charges  of at least 2.5 or
higher for the  previous 12 months.  For 2000,  this  calculation  excludes  the
impact  of the  Hales  judgment.  At the  end of  2000,  the  Company's  capital
structure  consisted of 73.7% debt (including  short-term debt but excluding the
Company's  several  guarantee of NOARK's  obligations) and 26.3% equity,  with a
ratio of EBITDA to fixed  charges of 4.1.  Over the long term,  the Company will
continue to consider the sale of its  remaining gas  distribution  assets to pay
down existing debt.

                                       33

In the short  term,  funds  provided by  operating  activities  are  expected to
increase significantly due to higher gas and oil prices currently being received
for the Company's production.  As part of its strategy to reduce its debt level,
the Company has hedged approximately 80% of its expected 2001 gas production and
50% of its expected 2001 oil production to insure it receives attractive prices.
Under these assumptions and assuming no other  unanticipated  uses of cash arise
during the year, the Company  expects to reduce its debt level by $50 million to
$70 million during 2001.

Working Capital
         The  Company  maintains  access  to funds  which  may be needed to meet
seasonal  requirements  through its credit facility explained above. The Company
had net negative working capital of $127.0 million at the end of 2000 due to the
short-term  revolving  credit facility  balance of $171.0  million,  compared to
positive  working  capital of $13.9 million at the end of 1999.  Current  assets
increased by 61% to $112.9 million in 2000, while current  liabilities  (without
consideration of short-term debt) increased 41%. The increases in current assets
and current  liabilities at December 31, 2000, was due primarily to increases in
accounts  receivable,  accounts payable and under-recovered  purchased gas costs
that resulted from extremely high market prices for natural gas at year end.

FORWARD-LOOKING INFORMATION
         All statements,  other than historical financial information,  included
in this discussion and analysis of financial condition and results of operations
may be deemed to be forward-looking statements within the meaning of Section 27A
of the  Securities  Act of 1933, as amended,  and Section 21E of the  Securities
Exchange Act of 1934, as amended. Although the Company believes the expectations
expressed  in  such   forward-looking   statements   are  based  on   reasonable
assumptions, such statements are not guarantees of future performance and actual
results or developments may differ materially from those in the  forward-looking
statements.  Important  factors  that  could  cause  actual  results  to  differ
materially from those in the forward-looking  statements herein include, but are
not limited to, the timing and extent of changes in commodity prices for gas and
oil, the effects of commodity  hedges and the  volatility in earnings  caused by
new hedge accounting  standards,  the timing and extent of the Company's success
in discovering,  developing,  producing, and estimating reserves, the effects of
weather and regulation on the Company's gas distribution segment, the value that
the  Company's   gas   distribution   segment  may  bring  in  exploring   sales
opportunities  for this segment and the timing of any proposed  sale,  increased
competition,  legal and  economic  factors,  governmental  regulation,  changing
market  conditions,  the comparative  cost of alternative  fuels,  conditions in
capital  markets  and  changes  in  interest  rates,  availability  of oil field
services,  drilling rigs, and other equipment,  as well as various other factors
beyond the Company's control.

ITEM 7.A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

         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
7% of accounts  receivable.  See the discussion of credit risk  associated  with
commodities trading below.

                                       34

Interest Rate Risk
         The following  table provides  information  on the Company's  financial
instruments  that are sensitive to changes in interest rates. The table presents
the   Company's   debt   obligations,   principal   cash   flows   and   related
weighted-average  interest rates by expected  maturity dates.  Variable  average
interest  rates reflect the rates in effect at December 31, 2000 for  borrowings
under the Company's credit facility.  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 December 31, 2000.

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  markets.  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.

         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) or 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 December 31,
2000. At December 31, 2000, the "Carrying Amount" of these financial instruments
exceeded the "Fair Value" by $60.6 million.

Report of Management

         Management  is  responsible  for the  preparation  and integrity of the
Company's financial  statements.  The financial statements have been prepared in
accordance with accounting  principles  generally  accepted in the United States
consistently  applied,  and  necessarily  include some amounts that are based on
management's best estimates and judgment.

         The   Company   maintains   a  system  of   internal   accounting   and
administrative  controls that management  believes provide reasonable  assurance
that assets are  safeguarded  and that  transactions  are properly  recorded and
executed in accordance with management's authorization.  The Company's financial
statements  have been  audited by its  independent  public  accountants,  Arthur
Andersen LLP. In accordance with auditing  standards  generally  accepted in the
United States, the independent  auditors obtained a sufficient  understanding of
the  Company's  internal  controls to plan their audit and determine the nature,
timing, and extent of other tests to be performed.

         The Audit  Committee  of the  Board of  Directors,  composed  solely of
outside  directors,  meets with  management  and Arthur  Andersen  LLP to review
planned audit scopes and results and to discuss other matters affecting internal
accounting  controls and  financial  reporting.  The  independent  auditors have
direct  access to the Audit  Committee  and  periodically  meet with it  without
management representatives present.

Report of Independent Public Accountants

To the Board of Directors and Shareholders of Southwestern Energy Company:

         We have audited the consolidated  balance sheets of SOUTHWESTERN ENERGY
COMPANY (an Arkansas  corporation)  AND SUBSIDIARIES as of December 31, 2000 and
1999, and the related consolidated statements of operations,  retained earnings,
and cash flows for each of the three  years in the  period  ended  December  31,
2000.  These  financial  statements  are  the  responsibility  of the  Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

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

         In our opinion,  the  financial  statements  referred to above  present
fairly, in all material respects,  the financial position of Southwestern Energy
Company and  Subsidiaries  as of December 31, 2000 and 1999,  and the results of
their  operations and their cash flows for each of the three years in the period
ended  December 31, 2000, in conformity  with  accounting  principles  generally
accepted in the United States.

Notes to Financial Statements
Southwestern Energy Company and Subsidiaries
December 31, 2000, 1999, and 1998

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations and Consolidation
         Southwestern  Energy  Company  (Southwestern  or  the  Company)  is  an
integrated  energy  company  primarily  focused  on  natural  gas.  Through  its
wholly-owned subsidiaries, the Company is engaged in oil and gas exploration and
production,  natural gas gathering,  transmission and marketing, and natural gas
distribution.   Southwestern's   exploration   and  production   activities  are
concentrated in Arkansas,  New Mexico,  Texas,  Oklahoma and Louisiana.  The gas
distribution  segment  operates in northern  Arkansas and under  normal  weather
conditions  obtains  approximately  35% to 40% of its gas supply from one of the
Company's  exploration  and  production  subsidiaries.  The customers of the gas
distribution segment consist of residential, commercial, and industrial users of
natural  gas.   Southwestern's   marketing   and   transportation   business  is
concentrated in its core areas of operations.

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

         The  consolidated   financial   statements   include  the  accounts  of
Southwestern  Energy  Company and its  wholly-owned  subsidiaries,  Southwestern
Energy  Production   Company,   SEECO,  Inc.,   Arkansas  Western  Gas  Company,
Southwestern   Energy  Services   Company,   Diamond  "M"  Production   Company,
Southwestern Energy Pipeline Company,  A.W. Realty Company, and Arkansas Western
Pipeline Company.  All significant  intercompany  accounts and transactions have
been eliminated.  The Company accounts for its general  partnership  interest in
the NOARK Pipeline System,  Limited  Partnership (NOARK) using the equity method
of accounting.  In accordance with Statement of Financial  Accounting  Standards
(SFAS) No. 71,  "Accounting for the Effects of Certain Types of Regulation," the
Company  recognizes profit on intercompany  sales of gas delivered to storage by
its utility subsidiary.  Certain  reclassifications  have been made to the prior
years'  financial  statements  to  conform  with  the 2000  presentation.  These
reclassifications had no effect on previously recorded net income.

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

Unusual Items
         In June 2000,  the Company  reported  that the Arkansas  Supreme  Court
ruled to affirm the 1998 decision of the Sebastian County Circuit Court awarding
$109.3  million  in a class  action to  royalty  owners of  SEECO,  Inc.  (Hales
judgment).  The Company  fully  satisfied  the judgment and the Circuit Court in
Sebastian  County  issued  an order in  complete  satisfaction  of the  judgment
effective July 18, 2000. Additionally, the Company incurred an unusual charge of
$2.0 million related to other ongoing litigation.

                                       42

Property, Depreciation, Depletion and Amortization
         Gas and Oil  Properties  - The Company  follows the full cost method of
accounting  for the  exploration,  development,  and  acquisition of gas and oil
reserves.  Under this  method,  all such costs  (productive  and  nonproductive)
including salaries,  benefits, and other internal costs directly attributable to
these  activities are  capitalized  and amortized on an aggregate basis over the
estimated  lives of the properties  using the  units-of-production  method.  The
Company   excludes  all  costs  of   unevaluated   properties   from   immediate
amortization.  The Company's  unamortized  costs of oil and gas  properties  are
limited to the sum of the future net revenues attributable to proved oil and gas
reserves  discounted at 10 percent plus the lower of cost or market value of any
unproved  properties.  If  the  Company's  unamortized  costs  in  oil  and  gas
properties exceed this ceiling amount, a provision for additional  depreciation,
depletion and amortization is required. At June 30, 1998, the Company recognized
a $40.5 million non-cash charge to earnings by recording a write-down of its oil
and gas properties of $66.4 million and a related reduction in the provision for
deferred  income taxes of $25.9 million.  At December 31, 2000,  1999, and 1998,
the  Company's  net book  value of oil and gas  properties  did not  exceed  the
ceiling amounts.  Market prices,  production rates, levels of reserves,  and the
evaluation of costs excluded from  amortization all influence the calculation of
the full cost ceiling.

         Gas Distribution Systems - Costs applicable to construction activities,
including overhead items, are capitalized.  Depreciation and amortization of the
gas distribution system is provided using the straight-line  method with average
annual rates for plant  functions  ranging from 1.7% to 5.9%. Gas in underground
storage is stated at average cost.

         Other   property,   plant  and  equipment  is  depreciated   using  the
straight-line method over estimated useful lives ranging from 5 to 35 years.

         The Company  charges to  maintenance  or operations  the cost of labor,
materials,  and other expenses incurred in maintaining the operating  efficiency
of  its  properties.  Betterments  are  added  to  property  accounts  at  cost.
Retirements are credited to property, plant and equipment at cost and charged to
accumulated  depreciation,  depletion  and  amortization  with  no  gain or loss
recognized, except for abnormal retirements.

         Capitalized   Interest  -  Interest  is  capitalized  on  the  cost  of
unevaluated  gas and oil properties  excluded from  amortization.  In accordance
with established utility regulatory practice, an allowance for funds used during
construction  of major projects is capitalized  and amortized over the estimated
lives of the related facilities.

Gas Distribution Revenues and Receivables
         Customer  receivables  arise from the sale or  transportation of gas by
the  Company's  gas   distribution   subsidiary.   The  Company's   136,000  gas
distribution  customers  are  located  in  northern  Arkansas  and  represent  a
diversified base of residential,  commercial,  and industrial users. The Company
records gas distribution  revenues on an accrual basis, as gas volumes are used,
to provide a proper matching of revenues with expenses.

         The gas distribution  subsidiary's rate schedules include purchased gas
adjustment  clauses  whereby the actual cost of purchased gas above or below the
level  included in the base rates is permitted to be billed or is required to be
credited to  customers.  Each month,  the  difference  between  actual  costs of
purchased gas and gas costs  recovered from customers is deferred.  The deferred
differences are billed or credited,  as appropriate,  to customers in subsequent
months.  Rate  schedules  include a weather  normalization  clause to lessen the
impact of revenue  increases  and  decreases  which might  result  from  weather
variations  during the winter heating season.  The  pass-through of gas costs to
customers is not affected by this normalization clause.

                                       43

Gas Production Imbalances
         The exploration and production  subsidiaries record gas sales using the
entitlement  method. The entitlement method requires revenue  recognition of the
Company's  revenue interest share of gas production from properties in which gas
sales are  disproportionately  allocated to owners because of marketing or other
contractual  arrangements.  The Company's net imbalance position at December 31,
2000 and 1999 was not significant.

Income Taxes
         Deferred  income taxes are provided to recognize  the income tax effect
of  reporting  certain  transactions  in  different  years  for  income  tax and
financial reporting purposes.

Risk Management
         The Company uses  derivative  financial  instruments  to manage defined
commodity  price risks and does not use them for trading  purposes.  The Company
uses  commodity  swap  agreements  and options to hedge sales of natural gas and
crude  oil.  Gains  and  losses  resulting  from  hedging  activities  have been
recognized when the related  physical  transactions  were  recognized.  Gains or
losses from  commodity  swap  agreements  and  options  that did not qualify for
accounting treatment as hedges have been recognized currently as other income or
expense. See Note 8 for a discussion of the Company's commodity hedging activity
and the  impact  of the  adoption  of SFAS  No. 133, "Accounting  for Derivative
Instruments and Hedging Activities."

Earnings Per Share and Shareholders' Equity
         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 2,602,800 shares with an average exercise price of $9.79 outstanding
at December 31, 2000 and options for  1,634,901  shares with a weighted  average
exercise price of $12.15  outstanding at December 31, 1998. Due to the Company's
net loss for 2000 and 1998, these incremental shares would have an anti-dilutive
effect  and were,  therefore,  not  considered.  The  Company  had  options  for
1,275,899  shares of common  stock with a  weighted  average  exercise  price of
$12.97 per share at December 31, 1999, that were not included in the calculation
of diluted  shares  because  they would have had an  anti-dilutive  effect.  The
remaining  785,300 options at December 31, 1999 with a weighted average exercise
price of $6.46 were included in the calculation of diluted shares.

         During 2000 and 1999, the Company  issued 154,438 and 105,436  treasury
shares,  respectively,  under a  compensatory  plan  and for  stock  awards  and
returned  to  treasury  10,955 and 2,300  shares,  respectively,  canceled  from
earlier issues under the compensatory plan. The net effect of these transactions
was a $1.6  million  decrease  in 2000 and a $1.2  million  decrease  in 1999 in
treasury stock.

Dividend on Common Stock
         As a result of the adverse Hales judgment in June 2000, the Company has
indefinitely suspended payment of quarterly dividends on its common stock.

================================================================================


         In July 2000,  the  Company  replaced  its  existing  revolving  credit
facilities  with a new 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 9.36% Senior Notes.
The new credit facility is also being used to fund normal working capital needs.
The new credit facility has a term of 364 days, with interest generally based at
112.5 basis points over the LIBOR rate. The Company  intends to renew or replace
this facility prior to its expiration.

         In August  2000,  the Company  retired  $22.0  million of 9.36%  Senior
Notes.  Certain costs of the  redemption  were expensed and are classified as an
extraordinary  loss,  net of related  income tax  effects,  in the  accompanying
financial statements.

         The terms of the debt  instruments  and  agreements  contain  covenants
which  impose  certain  restrictions  on  the  Company,  including  limiting  of
additional  indebtedness  and  prohibiting  the payment of cash  dividends.  The
Company was in compliance with its debt agreements at December 31, 2000.

         There are no aggregate  maturities  of  long-term  debt for each of the
years ending  December 31, 2001 through  2004.  For the year ended  December 31,
2005, the aggregate  maturity is $125.0  million.  Total interest  payments were
$23.6 million in 2000 and $19.6 million in 1999 and 1998.

         The provision (benefit) for income taxes was an effective rate of 38.7%
in 2000,  39.4% in  1999,  and  38.9% in  1998.  The  following  reconciles  the
provision (benefit) for income taxes included in the consolidated  statements of

         The Company's  supplemental  retirement plan has an accumulated benefit
obligation in excess of plan assets. The plan's  accumulated  benefit obligation
was $286,000 and $233,000 at December 31, 2000 and 1999, respectively. There are
no plan  assets in the  supplemental  retirement  plan due to the  nature of the
plan.

==============================================================================================


         Prior to 1998, the Company's  pension plans provided for benefits based
on years  of  benefit  service  and the  employee's  "average  compensation"  as
defined.  During 1998,  the Company  amended its plans to become "cash  balance"
plans on a prospective basis. A cash balance plan provides benefits based upon a
fixed percentage of an employee's  annual  compensation.  The Company's  funding
policy is to contribute amounts which are actuarially  determined to provide the
plans with  sufficient  assets to meet future benefit payment  requirements  and
which are tax deductible.

         The postretirement  benefit plans provide  contributory health care and
life insurance  benefits.  Employees  become eligible for these benefits if they
meet age and service  requirements.  Generally,  the benefits  paid are a stated
percentage  of medical  expenses  reduced by  deductibles  and other  coverages.
During 1998, the Company established trusts to partially fund its postretirement
benefit obligations.

         The  weighted  average  assumptions  used  in  the  measurement  of the
Company's benefit obligations for 2000 and 1999 are as follows:


                                                            Other Postretirement

                                     -------------------------------------------

================================================================================


         For measurement purposes a 9% annual rate of increase in the per capita
cost of covered  medical  benefits  and an 8% annual rate of increase in the per
capita cost of dental benefits was assumed for 2001. These rates were assumed to
gradually  decrease to 6% for medical  benefits  and 5% for dental  benefits for
2011 and remain at that level thereafter.

                                       48

         Assumed  health care cost trend rates have a significant  effect on the
amounts  reported for the health care plans.  A one  percentage  point change in
assumed health care cost trend rates would have the following effects:


                                                      1% Increase    1% Decrease

         The results of operations shown above exclude unusual items in 2000 and
overhead and interest  costs in all years.  Income tax expense is  calculated by
applying  the  statutory  tax  rates  to  the  revenues  less  costs,  including
depreciation,  depletion and amortization,  and after giving effect to permanent
differences and tax credits.

         The table below sets forth  capitalized  costs  incurred in gas and oil
property acquisition, exploration, and development activities during 2000, 1999,
and 1998:

         Capitalized  interest  is  included  as part of the cost of oil and gas
properties. The Company capitalized $2.4 million, $3.3 million, and $3.9 million
during 2000,  1999,  and 1998,  respectively,  based on the  Company's  weighted
average cost of borrowings used to finance the expenditures.

         In addition to  capitalized  interest,  the  Company  also  capitalized
internal  costs of $7.3  million,  $7.4 million,  and $7.7 million  during 2000,
1999, and 1998,  respectively.  These  internal  costs were directly  related to
acquisition,  exploration and development activities and are included as part of
the cost of oil and gas properties.

                                       49

         The  following  table  shows  the  capitalized  costs  of gas  and  oil

         The table below sets forth the  composition  of net  unevaluated  costs
excluded from amortization as of December 31, 2000. Of the total,  approximately
$12.8  million is invested in  Louisiana.  The majority of  Louisiana  costs are
related to seismic  projects  that will be evaluated  over several  years as the
seismic data is  interpreted  and the acreage is explored.  The remaining  costs
excluded from  amortization are related to properties which are not individually
significant  and on which the  evaluation  process has not been  completed.  The
Company is,  therefore,  unable to estimate when these costs will be included in
the amortization computation.

         The "Standardized  Measure of Discounted Future Net Cash Flows Relating
to Proved Oil and Gas Reserves"  (standardized measure) is a disclosure required
by SFAS No.  69,  "Disclosures  About  Oil and Gas  Producing  Activities."  The
standardized  measure  does not purport to present  the fair  market  value of a
company's  proved gas and oil  reserves.  In addition,  there are  uncertainties
inherent  in  estimating  quantities  of  proved  reserves.   Substantially  all
quantities  of gas and oil  reserves  owned by the  Company  were  estimated  or
audited  by  the  independent  petroleum  engineering  firm  of  K  &  A  Energy
Consultants, Inc.

         Following  is the  standardized  measure relating to proved gas and oil
reserves at December 31, 2000, 1999, and 1998:


                                                                 2000         1999         1998

===============================================================================================

         Under the standardized  measure,  future cash inflows were estimated by
applying  year-end  prices,  adjusted  for  known  contractual  changes,  to the
estimated  future  production of year-end proved  reserves.  Future cash inflows
were reduced by  estimated  future  production  and  development  costs based on
year-end  costs to  determine  pretax cash  inflows.  Future  income  taxes were
computed by  applying  the  year-end  statutory  rate,  after  consideration  of
permanent  differences,  to the excess of pretax cash inflows over the Company's
tax basis in the  associated  proved  gas and oil  properties.  Future  net cash
inflows after income taxes were  discounted  using a 10% annual discount rate to
arrive at the standardized measure.

         Following is an analysis of changes in the standardized  measure during
2000, 1999, and 1998:

(7) INVESTMENT IN UNCONSOLIDATED PARTNERSHIP

         The Company holds a 25% general  partnership  interest in NOARK.  NOARK
Pipeline was formerly a 258-mile long intrastate gas  transmission  system which
extended across northern Arkansas.  In January 1998, the Company entered into an
agreement with Enogex Inc.  (Enogex) that resulted in the expansion of the NOARK
Pipeline and provided the pipeline with access to Oklahoma gas supplies  through
an integration of NOARK with the Ozark Gas Transmission  System (Ozark).  Enogex
is a subsidiary  of OGE Energy Corp.  Ozark was a 437-mile  interstate  pipeline
system  which began in eastern  Oklahoma  and  terminated  in eastern  Arkansas.
Enogex  acquired  the Ozark  system and  contributed  it to NOARK.  Enogex  also
acquired  the  NOARK  partnership  interests  not  owned  by  Southwestern.  The
acquisition of Ozark and its integration with NOARK Pipeline was approved by the
Federal Energy  Regulatory  Commission in late 1998 at which time NOARK Pipeline
was converted to an interstate  pipeline and operated in combination with Ozark.
Enogex funded the  acquisition of Ozark and the expansion and  integration  with
NOARK  Pipeline  which  resulted  in the  Company's  ownership  interest  in the
partnership decreasing to 25% from 48%.

         The Company's investment in NOARK totaled $15.5 million at December 31,
2000 and $14.0 million at December 31, 1999,  including advances of $3.3 million
made during 2000,  $2.3 million made during 1999,  and $10.1 million made during
1998.  Advances in 1998  included the  Company's  share of costs  related to the
prepayment of NOARK's Senior Secured Notes. Other advances are made primarily to
service NOARK's  long-term  debt. See Note 11 for further  discussion of NOARK's
funding requirements and the Company's investment in NOARK.

         NOARK's financial  position at December 31, 2000 and 1999 is summarized
below:

(8) FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

Fair Value of Financial Instruments
         The following  methods and  assumptions  were used to estimate the fair
value of each class of  financial  instruments  for which it is  practicable  to
estimate the value:
         Cash, Customer Deposits, and Short-Term Debt:  The carrying amount is a
reasonable estimate of fair value.
         Long-Term Debt:  The fair  value  of the  Company's  long-term  debt is
estimated based  on the expected  current rates  which would  be offered  to the
Company for debt of the same maturities.
         Commodity Hedges:  The fair value of all hedging financial  instruments
is the amount at which they could be settled,  based on quoted  market prices or
estimates obtained from dealers.  The carrying amounts and estimated fair values
of the Company's financial  instruments as of December 31, 2000 and 1999 were as
follows:


                                           2000                      1999

Derivatives and Price Risk Management
         SFAS No.  133,  "Accounting  for  Derivative  Instruments  and  Hedging
Activities,"  as amended  by SFAS No. 137 and SFAS No.  138,  is  effective  for
fiscal years  beginning after June 15, 2000 and requires that all derivatives be
recognized  as  assets  or  liabilities  in the  balance  sheet  and that  these
instruments be measured at 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.  Additionally,  the Company recorded a net of
tax cumulative  loss to retained  earnings of $1.7 million and a net of tax loss
to other  comprehensive  income  (equity  section of the balance sheet) of $35.4
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.

         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 appropriate
credit standings.

         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

                                       53

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
"ceiling"  price  above which the Company  pays the  counterparty  the amount by
which the price of the commodity is above the contracted ceiling.

         At December 31,  2000,  the Company had collars in place on 31.2 Bcf of
future gas production.  Of this total,  21.9 Bcf had floors and ceilings ranging
from $3.50 to $6.00, respectively. The remaining 9.3 Bcf had floors and ceilings
ranging from $2.50 to $3.50, respectively. Additionally, the Company had collars
on 300,000 barrels of crude oil with floors and ceilings  ranging from $27.00 to
$30.33, respectively.

         At December 31,  2000,  the Company had  outstanding  natural gas price
swaps on total  notional  volumes of 3.1 Bcf for which the Company  will receive
fixed prices  ranging from $2.57 to $4.62 per MMBtu.  Under  contracts on .4 Bcf
the  Company  will make  average  fixed  price  payments  of $4.83 per MMBtu and
receive variable prices based on the NYMEX futures market. At December 31, 2000,
the Company  also had  outstanding  crude oil swaps to receive  fixed  prices of
$17.49 per barrel in 2001 on notional  volumes of 72,000 barrels.  The Company's
price risk management activities reduced revenues $39.3 million in 2000 and $1.1
million in 1999, and increased revenues $7.4 million in 1998.

         At December 31,  2000,  the Company also had an $18.00 per barrel floor
on 325,000  barrels.  Subsequent  to December 31, 2000,  the Company  closed its
position on this oil floor.  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.

(9) STOCK OPTIONS

         The  Southwestern  Energy Company 2000 Stock Incentive Plan (2000 Plan)
was adopted in February, 2000 and provides for the compensation of officers, key
employees   and  eligible   non-employee   directors  of  the  Company  and  its
subsidiaries.  The 2000 Plan replaces the Southwestern Energy Company 1993 Stock
Incentive  Plan  (1993  Plan) and the  Southwestern  Energy  Company  1993 Stock
Incentive  Plan for  Outside  Directors  (1993  Director  Plan).  The 2000  Plan
provides for grants of options,  stock  appreciation  rights,  shares of phantom
stock,  and  shares of  restricted  stock  that in the  aggregate  do not exceed
1,250,000 shares. The types of incentives which may be awarded are comprehensive
and are  intended  to  enable  the  Board of  Directors  to  structure  the most
appropriate  incentives  and to address  changes in income tax laws which may be
enacted over the term of the 2000 Plan.

         The  1993  Plan  provided  for the  compensation  of  officers  and key
employees of the Company and its subsidiaries through grants of options,  shares
of  restricted  stock,  and stock  bonuses that in the  aggregate did not exceed
1,700,000  shares,  the grant of stand-alone stock  appreciation  rights (SARs),
shares of phantom  stock and cash  awards,  the  shares  related to which in the
aggregate did not exceed 1,700,000  shares,  and the grant of limited and tandem
SARs (all terms as defined in the 1993 Plan). The Company has also awarded stock
option  grants  outside  the 2000 Plan and the 1993 Plan to certain  non-officer
employees and to certain officers at the time of their hire.

                                       54

         The 2000 Plan  awards  each  non-employee  director  who is eligible to
participate in the plan an annual Director's Option with respect to 8,000 shares
of common  stock.  Previously,  the 1993 Director Plan provided for annual stock
option grants of 12,000 shares (with 12,000  limited SARs) to each  non-employee
director.  Options  under the 1993  Director  Plan were  limited to no more than
240,000 shares.

         The  Company's  1985  Nonqualified  Stock  Option Plan expired in 1992,
except with respect to awards then  outstanding.  The following tables summarize
stock option activity for the years 2000, 1999, and 1998 and provide information

         All options  are issued at fair  market  value at the date of grant and
expire ten years from the date of grant. Options generally vest to employees and
directors over a three to four year period from the date of grant.  Of the total
options  outstanding,  325,000  performance  accelerated options were granted in
1994 at an option price of $14.63.  These  options vest over a four-year  period
beginning in 2000.

         The Company has granted 453,165 shares of restricted stock to employees
through 2000. Of this total,  410,615  shares vest over a three-year  period and
the  remaining  shares vest over a five-year  period.  The related  compensation
expense is being  amortized over the vesting  periods.  As of December 31, 2000,
189,512  shares have vested to employees and 22,201  shares have been  cancelled
and returned to treasury shares.

                                       55

         The Company  applies the  disclosure-only  provisions  of SFAS No. 123,
"Accounting for Stock-Based Compensation." Accordingly, no compensation cost has
been  recognized  for the stock  option  plans.  Had  compensation  cost for the
Company's stock option plans been  determined  consistent with the provisions of
SFAS No. 123, the  Company's  net income  (loss) and  earnings  (loss) per share
would have been reduced to the pro forma amounts indicated below:


                                                    2000       1999         1998

Net income (loss), in thousands
  As reported                                  $(46,687)     $9,927     $(30,597)
  Pro forma                                    $(47,444)     $9,241     $(31,201)
Basic earnings (loss) per share
  As reported                                    $(1.86)       $.40       $(1.23)
  Pro forma                                      $(1.90)       $.37       $(1.25)
Diluted earnings (loss) per share
  As reported                                    $(1.86)       $.40       $(1.23)
  Pro forma                                      $(1.90)       $.37       $(1.25)


         Because the SFAS No. 123 method of  accounting  has not been applied to
options  granted prior to January 1, 1995, the resulting pro forma  compensation
cost may not be  representative of that to be expected in future years. The fair
value  of each  option  grant  is  estimated  on the  date of  grant  using  the
Black-Scholes   option   pricing  model  with  the  following   weighted-average
assumptions: no dividend yield; expected volatility of 44.0%; risk-free interest
rate of 6.0%; and expected lives of 6 years.

(10) COMMON STOCK PURCHASE RIGHTS

         In 1999, the Company's  Common Share  Purchase  Rights Plan was amended
and extended for an additional ten years. Per the terms of the amended plan, one
common  share  purchase  right  is  attached  to each  outstanding  share of the
Company's common stock.  Each right entitles the holder to purchase one share of
common stock at an exercise price of $40.00, subject to adjustment. These rights
will  become  exercisable  in the  event  that a  person  or group  acquires  or
commences  a  tender  or  exchange  offer  for  15% or  more  of  the  Company's
outstanding  shares or the Board  determines that a holder of 10% or more of the
Company's  outstanding  shares  presents a threat to the best  interests  of the
Company. At no time will these rights have any voting power.

         If any person or entity actually  acquires 15% of the common stock (10%
or more if the Board determines such acquiror is adverse),  rightholders  (other
than the 15% or 10%  stockholder)  will be entitled to buy, at the right's  then
current  exercise price, the Company's common stock with a market value of twice
the exercise price.  Similarly,  if the Company is acquired in a merger or other
business  combination,  each right will entitle its holder to  purchase,  at the
right's then current exercise price, a number of the surviving  company's common
shares having a market value at that time of twice the right's exercise price.

                                       56

         The rights may be redeemed by the Board for $.01 per right or exchanged
for common  shares on a  one-for-one  basis  prior to the time that they  become
exercisable.  In the event, however, that redemption of the rights is considered
in connection with a proposed  acquisition of the Company,  the Board may redeem
the  rights   only  on  the   recommendation   of  its   independent   directors
(nonmanagement  directors who are not  affiliated  with the proposed  acquiror).
These rights expire in 2009.

(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.
The  Company's  share of the several  guarantee is 60%. At December 31, 2000 and
1999,  the  principal  outstanding  for these Notes was $75.0  million and $77.0
million,   respectively.  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,  as discussed further in Note 7, 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.

         In its Form 8-K  filed  July 2,  1996,  the  Company  disclosed  that a
lawsuit relating to overriding royalty interests in certain Arkansas oil and gas
properties had been filed against it and two of its  wholly-owned  subsidiaries.
This matter went to a non-jury  trial as to liability  on January 10, 2000.  The
court in this matter issued  Findings of Fact and  Conclusions of Law that found
no fraud was committed. The court also found that any override royalty interests
that  might  ultimately  be found to be due  under  the  plaintiffs'  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
proceeding that is scheduled for April 30, 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 United States Minerals  Management  Service (MMS), a federal agency
responsible  for  the   administration   of  federal  oil  and  gas  leases,  is
investigating  the Company and its  subsidiaries in respect of claims similar to
those in the Hales class action  royalty  litigation  previously  reported.  The
Company was found to be ultimately  liable in the Hales litigation and satisfied
the  judgment  in July 2000.  MMS was  included in the class  action  litigation
against its objections,  but did not pursue further action to remove itself from
the class.

                                       57

         On August 25, 2000,  a class action suit was filed  against the Company
and its  subsidiaries in Sebastian  County,  Arkansas,  on behalf of all mineral
owners who own or owned a royalty and/or overriding  royalty interest in oil and
gas leases or other agreements in certain sections of Franklin County, Arkansas.
The Company was granted authority in 1968 by the Arkansas Oil and Gas Commission
to operate a gas storage facility in one section of Franklin County.  Based upon
subsequently  developed  geological data, the Company sought authority to expand
this area and was granted  authority by the Arkansas Oil and Gas  Commission  to
operate gas storage in  additional  sections.  Plaintiffs  are  challenging  the
storage agreements that the Company obtained from the mineral interest owners in
1968,  1999 and 2000 to operate the gas storage  facility  known as  "Stockton".
Plaintiffs allege various wrongful,  intentional and fraudulent acts relating to
the  operation  of the storage  pool  beginning  in 1968 and  continuing  to the
present and allege that the above-referenced  agreements from the mineral owners
were obtained  through  misrepresentation  and fraud.  The Company has owned and
operated  the Stockton  storage  unit  through its Arkansas  Western Gas Company
subsidiary  until  1994,  at which time it was  transferred  to its  subsidiary,
SEECO,  Inc.  Plaintiffs  claim ownership rights in the gas that the Company has
stored in the  storage  pool in an amount  in  excess  of $5  million  in actual
damages,  interest,  attorney's fees and punitive  damages.  The Company and its
outside  counsel believe that this action is without merit and does not meet the
requirements for a class action.  The Company believes that plaintiffs' claim to
the storage gas, which the Company has injected into the storage  facility,  has
no merit and is not  supported by the Arkansas gas storage  statute  under which
the  Company  operates  this  facility.  While the amount of this claim could be
significant,  management believes, based upon its investigation, that this claim
is without merit and that the Company's ultimate liability,  if any, will not be
material to its consolidated  financial position, but in any one period it could
be significant to its results of operations.

         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 non-capital  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.

(12) 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
is shown in the following  table.  The "Other" column  includes items related to
non-reportable  segments  (real estate and pipeline  operations)  and  corporate
items.
