                                     PART I
Item 1.    Business
     Southwestern  Energy  Company  (the  "Company"  or  "Southwestern")  is  an
integrated  energy  company  primarily  focused on natural  gas. The Company was
organized in 1929 as a local gas distribution company in northwest Arkansas. The
Company is incorporated under the laws of the state of Arkansas and is an exempt
holding company under the Public Utility Holding Company Act of 1935. Today, the
Company's operations are carried out by 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, south Louisiana, and
         the Gulf Coast.
     2.  Natural Gas Distribution -- Engaged in the gathering,  distribution and
         transmission  of natural  gas to  approximately  177,000  customers  in
         northern Arkansas and parts of Missouri.
     3.  Energy Services -- Provides marketing and transportation  services to a
         variety of commercial  and  industrial  customers in the  Mid-Continent
         area of the United States.  Supply  sources  include both Company owned
         natural gas and oil production as well as third-party production.  Owns
         a general  partnership  interest in the NOARK Pipeline System,  Limited
         Partnership (NOARK).

     Financial and operating statistics for Southwestern's business segments are
included in the Company's  consolidated  financial  statements,  incorporated by
reference  in  Part  II,  Item  8 of  this  report,  "Financial  Statements  and
Supplementary  Data".  A discussion of the primary  businesses  conducted by the
Company through its wholly-owned subsidiaries follows.

     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.

                           Exploration and Production

     In 1943, the Company commenced a program of exploration for 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 requirements.  Since that time, the Company's
exploration  and   development   activities   outside   Arkansas  have  expanded
substantially.  The Company's  exploration and production  activities consist of
ownership of mineral  interests in productive  and  undeveloped  leases  located
entirely within the United States.

     At December 31, 1997,  the Company had proved natural gas reserves of 291.4
billion  cubic  feet (Bcf) and proved oil  reserves  of 7,852  thousand  barrels
(MBbls). Revenues of the exploration and production

                                        1





subsidiaries are  predominately  generated from production of natural gas. Sales
of gas production accounted for 86% of total operating revenues for this segment
in 1997, 90% in 1996, and 93% in 1995.

Areas of Operation

     The Company 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  section of the Arkoma Basin.  SEPCO conducts
development  drilling  and  exploration  programs  in  areas  outside  Arkansas,
including  the Gulf Coast areas of Louisiana  and Texas,  the Anadarko  Basin of
Oklahoma,  and the  Permian  Basin of Texas and New  Mexico.  Diamond M operates
properties in the Permian Basin of Texas.

     During 1997,  Southwestern  brought in new senior  operating  management to
refocus its  exploration  and  production  segment.  In early 1998,  the Company
consolidated  its  exploration  and  land  efforts  to its  Houston  office  and
reorganized its staff into asset management teams. Three exploitation teams were
formed (an Arkoma  team, a  Mid-Continent  team and a Gulf Coast team) to manage
Southwestern's  producing  properties,  and three  exploration teams were formed
(two south  Louisiana teams and a new ventures team) to provide an area specific
focus in exploration projects.

     Arkoma.  Southwestern has been active in the Arkansas portion of the Arkoma
Basin since 1943. As a result,  it has acquired a substantial  acreage  position
and  reserve  base  in  the  basin.  At  December  31,  1997,  the  Company  had
approximately  213.4 Bcf of  natural  gas  reserves  in the Arkoma  Basin.  This
represents  73% of the Company's  natural gas reserves and 63% of total reserves
on a Bcf equivalent basis.  Southwestern's  average net daily production in 1997
in the Arkoma Basin was 62.0 million cubic feet equivalent (Mmcfe).

     In recent  years,  Southwestern  has  conducted  its  Arkansas  development
drilling  program  primarily  within the  boundaries  of its  utility  gathering
system.  In 1997, the Company  accelerated  the extension of its Arkoma drilling
program outside of its  traditional  areas to new fields.  Southwestern  enjoyed
successful stepout drilling in the lightly-explored southern edges of the Arkoma
Basin in Arkansas, as well as positive results from drilling in the western part
of the basin in Oklahoma.  Overall,  the Company  participated in 69 gross wells
(36.6 net) in the Arkoma Basin during 1997,  including 28 which were operated by
the Company.  These wells contributed 13.1 Bcf to total 1997 reserve  additions.
During 1998,  Southwestern  plans to continue to  capitalize  on its  geological
experience in the Arkoma Basin and increase its emphasis on development drilling
outside of the traditional Arkansas fairway.

     Mid-Continent.  The  Company's  activities  in this  region  are  primarily
focused on the  Anadarko  Basin of Oklahoma  and Permian  Basin of Texas and New
Mexico. Southwestern has been active in the Mid-Continent region since 1971. At
December 31, 1997, the Company had approximately 46.2 Bcf of natural

                                        2





gas reserves and 5,172 MBbls of oil reserves in the region, representing 16% and
66%,  respectively,  of the Company's  total gas and oil  reserves.  Average net
daily production in 1997 for this region was 23.9 Mmcfe.

     In recent years,  Southwestern  has  experienced  excellent  success in the
lower and middle Morrow formations in the Permian Basin in southeast New Mexico.
Since its first  exploratory  discovery  there in 1995,  the Company's  drilling
program in this area has resulted in 14 successful wells of 15 drilled. The most
recent  was the Gaucho #4,  which is  currently  flowing at a rate of 10 MMcf of
natural  gas per day.  Three  wells  have now been  drilled  within  the  Gaucho
prospect and are  producing  at a combined  daily rate of 25 MMcf of natural gas
and 125 barrels of condensate.  Southwestern  has a 50% working  interest in the
Gaucho unit.

     Gulf  Coast/South  Louisiana.  The Company  became active in the Gulf Coast
area in 1990. At December 31, 1997,  the Company had  approximately  30.8 Bcf of
natural gas reserves and 1,480 MBbls of oil reserves in the region, representing
11% and 19%, respectively,  of the Company's total gas and oil reserves. Average
net daily  production  in 1997 for this  region was 15.8  Mmcfe.  Southwestern's
initial  strategy  during  entry  into the  upper  Texas  Gulf  Coast  and south
Louisiana  revolved around  participating  in wells drilled to prove a prospect.
These exploratory wells had the potential for significant reserve additions, but
development  opportunities  were limited and a dry hole generally  condemned the
prospect.   This  strategy  did  not  meet  Southwestern's  reserve  growth  and
production  goals,  but it did enable the Company to establish a presence in the
region. As 3-D seismic  technology became more widely accepted as an exploration
tool,  Southwestern gained entry to a number of high potential joint ventures to
develop multiple,  high quality prospects.  The Company's typical project relies
on options to obtain access to leasehold  acreage over a large prospective area.
The  committed  acreage is  evaluated  for  leasing  after 3-D  seismic  data is
acquired, thus optimizing the Company's investment.

     The Company is actively  pursuing its exploration and development  strategy
in south  Louisiana.  Southwestern  has an inventory of over 400 square miles of
3-D  seismic  data and, at the end of 1997,  had  invested  approximately  $37.2
million in leasehold and seismic data acquisition costs related to the Company's
major  projects in south  Louisiana.  Each project is in a separate  development
stage, which maximizes  Southwestern's  ability to fully fund their development.
The Company's major exploration projects in south Louisiana are as follows:

     East Atchafalaya:  Southwestern became involved in this project in mid-1995
through a 50-50 joint  venture with Union Pacific  Resources.  The joint venture
has  acquired  113 square  miles of 3-D seismic  data  covering  portions of St.
Martin and Iberia Parishes,  Louisiana. During 1997, drilling was initiated. The
Company  participated  in four wells,  two deep tests and two  shallower  wells.
While  the  first  deep  test and one  shallow  well  did not find  commercially
productive  reserves,  the other  shallow well was  completed  in the  Planulina
formation  and is currently  producing 4 MMcf of natural gas per day. The fourth
well,  located in the Gator prospect,  was spudded in December,  1997, to test a
deep  Oligocene  target and reached its objective  total depth of 18,000 feet in
February,  1998. The well did not find  hydrocarbons  in the primary  objective,
however,  the  well has  been  completed  in a  shallower  secondary  objective.
Additional wildcat drilling is planned in 1998.

                                        3





     Henry:  This  project was  originated  by  Southwestern  and  includes  the
acquisition of approximately  110 square miles of 3-D seismic data in Vermillion
Parish,  Louisiana.  Southwestern's  Henry project continued on schedule in 1997
and drilling is expected in the second half of 1998.  Southwestern  received the
final  processed  3-D  data  in  September,  1997,  and  is in  the  process  of
interpreting this data. To date, a number of prospect leads have been identified
and prospect generation is ongoing. Southwestern plans to drill up to four wells
in Henry during 1998. The Company presently owns a 100% interest in the project.

     Boure[180]:  During  1997,  Southwestern  and its  partner  initiated a 185
square mile 3-D survey in  Assumption  Parish  adjacent to the East  Atchafalaya
project area.  Southwestern  has a 50% working  interest in the project.  Actual
shooting of the 3-D program  began in January,  1998,  with field work likely to
continue  through  the  middle of 1998.  Southwestern  should  begin to  receive
portions  of the 3-D  seismic  data in the second  half of 1998,  with  drilling
expected to begin in 1999.

     Southwestern  also has interests in three other smaller  prospect  areas in
south  Louisiana  which  are  supported  by 3-D  seismic  data  and  has  active
exploration  prospects in Oklahoma and New Mexico.  The Company's strategy is to
balance the risks inherent in its exploration program with continued development
drilling, primarily in the Arkoma Basin of Arkansas, and with producing property
acquisitions in its core operating areas.

Acquisitions

     In recent  years,  the Company  increased its emphasis on  acquisitions  of
producing  properties.  However,  in 1997,  the  market for  producing  property
acquisitions was  demand-driven  causing  existing  properties to sell at higher
prices as compared to historical  levels. As a result,  the Company did not make
any producing property  acquisitions in 1997, compared to $45.8 million spent in
1996,  $6.0  million  spent in 1995,  and $13.9  million  in 1994.  The  Company
acquired  approximately  32.7 Bcf of gas and 6,350 MBbls of oil during 1996, 4.5
Bcf of gas and 851 MBbls of oil during 1995, and 20.6 Bcf of gas and 1,038 MBbls
of oil during 1994. The 1996  acquisitions were primarily in Texas and Oklahoma,
the 1995  acquisitions  were  primarily in the Gulf Coast areas of Louisiana and
Texas,  and the  1994  acquisitions  were  primarily  in the  Anadarko  Basin of
Oklahoma.  The  largest  single  acquisition  completed  by  the  Company  was a
transaction  in which the  Company  acquired  substantially  all the oil and gas
properties owned by L.B. Simmons Energy, Inc. of Houston for $30.9 million.  The
acquisition  closed on November 1, 1996. Proved reserves acquired were 6 million
barrels of oil and 17 Bcf of natural  gas,  located  primarily in west Texas and
Oklahoma.  At the end of 1997,  oil accounted  for 14% of the  Company's  proved
reserves, up from 4% at the end of 1995, primarily due to this acquisition.

Capital Spending

     The  Company  expects  its  1998  capital  expenditures  for  gas  and  oil
exploration and  development to total $59.2 million,  down from $73.5 million in
1997.  During 1997, a large portion of capital  spending was devoted to land and
seismic data acquisition. Expenditures in 1998 will direct more funds toward the
drilling of exploratory  wells,  reflecting the inventory of drilling  prospects
which has been established.

Sales and Major Customers

     Natural gas  equivalent  production  rose to 104 million cubic feet per day
(MMcfd) in 1997, up from 101 MMcfd in 1996,  and 98 MMcfd in 1995.  The increase
in production was the ninth in the last ten years,  and  represented  the second
highest level in the Company's  history.  The Company's gas  production was 33.4
Bcf in 1997,  down from 34.8 Bcf in 1996, and 34.5 Bcf in 1995. The Company also
produced  749,000  barrels of oil in 1997, up from 391,000  barrels in 1996, and
229,000 barrels in 1995.

     The Company's natural gas production  received an average wellhead price of
$2.57 per thousand  cubic feet (Mcf) in 1997,  up from $2.26 per Mcf in 1996 and
$1.72 per Mcf in 1995. Oil prices were weaker,  with an average price in 1997 of
$19.02 per  barrel,  compared to $21.21 per barrel in 1996 and $17.15 per barrel
in 1995.

     Southwestern's  largest single  customer for sales of its gas production is
the  Company's  utility  subsidiary,  Arkansas  Western  Gas  Company  (Arkansas
Western). These sales are made by SEECO. Sales to Arkansas Western accounted for
approximately 42% of total  exploration and production  revenues in 1997, 46% in
1996, and 47% in 1995.  Sales to  unaffiliated  purchasers  accounted for 62% of
total  equivalent  oil and gas volumes sold by the  exploration  and  production
segment in 1997, 56% in 1996, and 61% in 1995.

     SEECO's  production  was 21.7 Bcf in 1997,  down  from 23.1 Bcf in 1996 and
24.3 Bcf in 1995.  SEECO's sales to Arkansas Western were 14.3 Bcf in 1997, down
from  16.3  Bcf  in  1996  and up  from  13.9  Bcf in  1995.  SEECO's  sales  to
unaffiliated  purchasers  were 7.4 Bcf in 1997, 6.8 Bcf in 1996, and 10.4 Bcf in
1995.

     Gas volumes sold by SEECO to Arkansas  Western for its  northwest  Arkansas
division  (AWG)  were  8.6 Bcf in 1997,  10.1 Bcf in 1996,  and 8.5 Bcf in 1995.
Through these sales,  SEECO  furnished 64% of the  northwest  Arkansas  system's
requirements  in  1997,  62% in  1996,  and 65% in 1995.  SEECO  also  delivered
approximately  1.0 Bcf in 1997, 1.1 Bcf in 1996, and 1.4 Bcf in 1995 directly to
certain large business customers of AWG through a transportation  service of the
utility  subsidiary.  Most of the  sales to AWG are  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  hereafter  referred  to as the "Gas  Cost
Settlement."  The Gas Cost Settlement  became  effective July 1, 1994, and calls
for sales  under the  contract to take place at a price which is equal to a spot
market index plus a premium. The amended contract provides that volumes equal to
the historical level of sales under the contract will be sold at the spot market
index plus a premium of $.95 per thousand  cubic feet (Mcf),  while  incremental
sales  volumes  receive a premium of $.50 per Mcf. In 1997,  8.2 Bcf (net to the
Company's interest) was sold under the contract, compared to 8.6 Bcf in 1996 and
7.7 Bcf in 1995.  The sales price under this contract  averaged $3.35 per Mcf in
1997,  $3.03 per Mcf in 1996, and $2.40 per Mcf in 1995.  This contract  expires
July 24,  1998.  AWG has  proposed to enter into a new  intersegment  gas supply
contract for a similar portion of its system needs at a price  competitive  with
the cost of alternative supplies.  For further discussion see "Gas Purchases and
Supply" under the "Natural Gas Distribution"  section below. In addition to this
contract,

                                        5





SEECO  also  sells gas to AWG under  newer  long-term  contracts  with  flexible
pricing provisions and under short-term spot market arrangements.

     SEECO's sales to Associated Natural Gas Company (Associated), a division of
Arkansas Western which operates  natural gas  distribution  systems in northeast
Arkansas and parts of Missouri,  were 5.7 Bcf in 1997,  6.2 Bcf in 1996, and 5.4
Bcf in 1995. These deliveries  accounted for  approximately  61% of Associated's
total  requirements  in 1997, 62% in 1996, and 59% in 1995.  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.  The sales
price  under  this  contract  was $2.20 per Mcf for the  contract  period  ended
September 30, 1995,  $1.785 per Mcf for the contract  period ended September 30,
1996, and $2.225 per Mcf for the contract  period ended  September 30, 1997. 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.  The sales price under the  contract  was $2.54 for the month of  December,
1997.

     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 is also  affected by the demand of the utility
for production on its gathering system. SEECO's sales to unaffiliated purchasers
accounted for approximately 15% of total exploration and production  revenues in
1997, 14% in 1996, and 21% in 1995.

     The combined gas production of SEPCO and Diamond M was 11.7 Bcf in 1997 and
1996, up from 10.3 Bcf in 1995. Oil  production was 749 MBbls in 1997,  compared
to 391  MBbls  in 1996  and 229  MBbls  in 1995.  The  increases  in  equivalent
production in 1997 and 1996 primarily  resulted from  acquisitions  of producing
properties  in recent years.  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 43% of total  exploration
and production revenues in 1997, 40% in 1996, and 32% in 1995.

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.

     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

                                        6





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  which may affect both
the price it receives and contract terms it must offer.  Outside  Arkansas,  the
Company is less  well-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 outside Arkansas.

                            Natural Gas Distribution

     The Company's  subsidiary  Arkansas Western Gas Company operates integrated
natural gas distribution systems concentrated primarily in northern Arkansas and
southeast  Missouri.  The  Arkansas  Public  Service  Commission  (APSC) and the
Missouri Public Service  Commission  (MPSC) regulate the Company's utility rates
and operations. The Company serves approximately 177,000 customers and obtains a
substantial  portion of the gas they consume  through its Arkoma Basin gathering
facilities.

     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  108,000  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  69,000 customers
primarily in northeast Arkansas and southeast Missouri.  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  directly  at the  wellhead  under
long-term contracts.  Purchases are made from approximately 246 working interest
owners  in  504  producing  wells.  As  previously  indicated,  SEECO  furnished
approximately 64% of AWG's system  requirements in 1997, 62% in 1996, and 65% in
1995.  A  significant  portion of AWG's  unaffiliated  supply  comes from market
responsive, long-term contracts.

     At December  31,  1997,  AWG had a gas supply  available  to its  northwest
Arkansas system of approximately 172 Bcf of proved developed reserves,  equal to
10.3 times current annual usage.  Of this total,  approximately  96 Bcf were net
reserves  available from SEECO. A portion of these reserves are utilized to meet
the  annual  sales  volume  commitment  of 9.0 Bcf  (gross)  under  the  amended
long-term  contract with AWG. For purposes of  determining  AWG's  available gas
supply,  deliveries to AWG's spot market  purchasing  program or  transportation
customers and the reserves related to those deliveries are not considered.

     AWG's  twenty-year gas supply contract with SEECO expires in July, 1998. In
March,  1997,  AWG filed a gas supply plan with the APSC which  projects  system
load growth patterns and long range gas supply

                                        7





needs for the utility's  northwest  Arkansas  system.  As part of its long range
supply  plan,  AWG has  proposed  to enter  into a new  intersegment  gas supply
contract for a similar portion of its system needs at a price  competitive  with
the cost of alternative supplies. The APSC has not yet approved AWG's gas supply
plan.  The Company  expects  that the volumes  will  continue to be sold to AWG.
However,  it is  possible  that the APSC may reject  AWG's gas  supply  plan and
require that the gas supply now provided under this contract be replaced through
a competitive bidding process,  involving multiple potential suppliers.  If this
occurs,  SEECO's  continued  sales of these volumes to AWG, and the price of any
such sales, will depend on the result of this competitive bidding process.

     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 liabilities  resulting from these contracts,  although the Company's
exposure to take-or-pay liabilities to its gas suppliers has increased in recent
years as a result of a decline  in its gas  supply  requirements.  This  decline
occurred  because  some  of  its  large  business  customers  converted  to  the
transportation service offered by AWG and began to obtain their own gas supplies
directly  from other  sources.  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 SEECO.  Purchases from SEECO are under
a  ten-year  contract  with  annual  price   redeterminations.   Purchases  from
unaffiliated suppliers are under firm contracts with terms between one and three
years. The rates charged by these suppliers  include demand components to ensure
availability of gas supply, administrative fees, and a commodity component which
is based on spot market gas prices.  Associated's  gas purchases are transported
through  eight  pipelines.  The pipeline  transportation  rates  include  demand
charges to reserve  pipeline  capacity and  commodity  charges  based on volumes
transported.  Associated has also contracted with five interstate  pipelines 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.

     AWG has no  restriction on adding new  residential or commercial  customers
and will supply new industrial  customers which 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.

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  155,000  residential,  22,000 commercial,  and 300
industrial  customers,  while also  providing  gas  transportation  services  to
approximately 50 end-use and off-system customers.  Total gas throughput in 1997
was 37.0 Bcf, down from 39.0 Bcf in

                                        8





1996, and 42.4 in 1995. Off-system  transportation volumes were 2.8 Bcf in 1997,
compared to 3.6 Bcf transported in 1996, and 9.8 Bcf transported in 1995.

     Residential and Commercial. Approximately 80% of the utility's revenues are
from residential and commercial  markets.  Residential and commercial  customers
combined  accounted  for 57% of total gas  throughput  for the gas  distribution
segment  in 1997 and 1996,  and 46% in 1995.  Gas  volumes  sold to  residential
customers  were 12.6  Bcf,  down from 13.4 Bcf sold in 1996 and up from 12.1 Bcf
sold in 1995.  Gas sold to commercial  customers  totaled 8.4 Bcf in 1997,  down
from 8.8 Bcf in 1996 and up from 7.6 Bcf in 1995.  The  decrease  in gas volumes
sold in 1997 was due to weather in Arkansas  Western's  service  territory which
was 5% warmer than in 1996,  partially  offset by customer growth of 2.2% in its
combined service territories during 1997.

     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  as a result of the
recently approved rate filings 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 include end-use transportation deliveries, have increased for the eleventh
consecutive  year,  reflecting  both the  success  of the  Company's  industrial
marketing efforts and the continued  economic strength of its service territory.
Industrial  customers,  which are generally smaller concerns using gas for plant
heating or product processing,  accounted for 13.2 Bcf in gas deliveries in 1997
and 1996, and 13.0 Bcf in 1995. No industrial customer accounts for more than 6%
of Arkansas Western's total throughput.

     In an effort  to more  fully  meet the  service  needs of  larger  business
customers,  both AWG and Associated instituted a transportation  service in 1991
that allows such customers in Arkansas to obtain their own gas supplies directly
from other  suppliers.  A total of 45 customers are currently using the Arkansas
transportation  service.  Eleven of AWG's twelve largest  customers in northwest
Arkansas,  including the seven largest,  are using the  transportation  service.
Associated's   four  largest   customers  in  northeast   Arkansas  and  ten  of
Associated's   eleven   largest   Missouri   customers   are   currently   using
transportation service.

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  which  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 is generally the least expensive,  most readily available
fuel in the service territories of AWG and Associated.

     The competition from  alternative  fuels and, in a limited number of cases,
alternative  sources of natural gas has intensified in recent years.  Industrial
customers are most likely to consider utilization of these

                                        9





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
nongas  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 and
MPSC. In Arkansas,  the Company operates through municipal  franchises which are
perpetual by state law. These  franchises,  however,  are not exclusive within a
geographic area. In Missouri,  the Company operates through municipal franchises
with various terms of existence.

     Over the past  several  years,  changes at the federal  level have  brought
significant changes to the regulatory  structure governing  interstate sales and
transportation of natural gas. The Federal Energy Regulatory Commission's (FERC)
Order No. 636 series  changed a major  portion of the gas  acquisition  merchant
function  provided to gas  distributors  by  interstate  pipelines.  AWG already
obtains its supply at the  wellhead  directly  from  producers  and has not been
directly impacted by Order No. 636.  Associated has acquired the bulk of its gas
supply at the wellhead since its acquisition by Arkansas Western,  but continued
until Order No. 636 to purchase a portion of both its peak and base requirements
from interstate suppliers. The changes mandated by Order No. 636 have placed the
responsibility  for  arranging  firm  supplies of natural gas  directly on local
distribution companies and have, as a result, lessened the ability of Associated
to purchase gas on the short-term spot market.

     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  are  presently  pending in  Arkansas  or  Missouri,  the  Company is
aggressively  controlling costs and constantly  evaluating issues such as system
capacity and  reliability,  obligation  to serve,  and rate design,  with an eye
toward minimizing any stranded or transition costs.

     Gas distribution revenues in future years will be impacted by both customer
growth and rate increases  allowed by regulatory  commissions.  In recent years,
AWG has experienced  customer growth of approximately  3% to 4% annually,  while
Associated has experienced  customer growth of approximately 1% annually.  Based
on current economic conditions in the Company's service territories, the Company
expects this trend in customer growth to continue. AWG and Associated pass along
to customers  through an automatic cost of gas adjustment clause any increase or
decrease  experienced  in purchased gas costs.  In December,  1996, AWG received
approval from the APSC for a rate increase of $5.1 million annually. The

                                       10





Company received approvals in December, 1997 from the APSC and the MPSC for rate
increases  and tariff  changes  for  Associated  which will allow the utility to
collect an  additional  $3.0 million  annually.  Of the $3.0  million  increase,
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. Rate increase requests which
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
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.

                                 Energy Services

Gas Marketing

     The energy  services  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.
During 1997, the group expanded its presence in natural gas marketing,  building
a diverse  customer base and providing a broad range of services at  competitive
prices.  In the future,  the energy  services  group plans to further expand its
natural gas  marketing  activities,  with  particular  emphasis  on  third-party
marketing in the Mid-Continent  region of the United States.  The planned merger
of NOARK with the Ozark Gas  Transmission  System (Ozark)  discussed  below will
afford greater supply and market opportunities, allowing the group to expand its
marketing operations in Oklahoma. Southwestern expects the contributions by this
segment to increase in  significance  as the pace of  deregulation in the energy
industry accelerates.

     The Company's marketing  operations include the marketing of Southwestern's
own gas production and third-party natural gas. The segment marketed 36.2 Bcf of
natural gas in 1997,  compared to 13.0 Bcf in 1996, and 19.9 Bcf in 1995. Of the
total volumes marketed,  purchases from the Company's exploration and production
subsidiaries accounted for 23% in 1997, 56% in 1996, and 59% in 1995.

Pipeline Operations

     A portion of the activity of the energy services segment involves the NOARK
Pipeline System,  Limited Partnership.  At December 31, 1997, the Company held a
48% general partnership interest in NOARK and served as the pipeline's operator.
The 258-mile long intrastate natural gas transmission system originates near the
Fort  Chaffee  military  reservation  in  western  Arkansas  and  terminates  in
northeast   Arkansas,    crossing   three   major   interstate   pipelines   and
interconnecting with the Company's  distribution systems.  NOARK's main line was
completed and placed in service in September, 1992. A lateral line of NOARK that
allows the  Company's  gas  distribution  segment  to  augment  its supply to an
existing market, as well as supply gas to new markets,  was completed and placed
in service in November,  1992. Construction of an eight-mile interstate pipeline
connecting NOARK to the  distribution  system of Associated was completed during
1993.

                                       11





AWG  provides  field  management  services  to NOARK  under a contract  with the
partnership and AWG's gathering  system delivers to NOARK a substantial  part of
the gas NOARK  transports.  In 1997, NOARK had an average daily throughput of 40
MMcfd,  compared  to 58  MMcfd in 1996,  and 86 MMcfd in 1995.  NOARK's  current
capacity is 141 MMcfd.  Arkansas  Western has  contracted for 52.3 MMcfd of firm
capacity on NOARK.  The contract  expires in 2002 and is renewable  year to year
until terminated with 180 days notice.

     While NOARK has always  accessed good  markets,  its  performance  has been
hindered  by a lack of  adequate  gas  supply.  NOARK has been  operating  below
capacity and  generating  losses since it was placed in service.  As a result of
these continuing  losses,  the Company  investigated  options to improve NOARK's
future  financial  prospects,  including an extension  into  Oklahoma that would
provide  additional  access to gas supply.  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
the integration of NOARK with the Ozark Gas Transmission  System (Ozark).  Ozark
is a 437-mile interstate  pipeline system which begins near McAlester,  Oklahoma
and  terminates  near  Searcy,  Arkansas.  Ozark has a  throughput  capacity  of
approximately  170 MMcfd.  Enogex has entered into an agreement to acquire Ozark
from NGC Corporation  for $55.0 million and will  contribute  Ozark to the NOARK
partnership when regulatory approvals are obtained. Enogex has also acquired the
NOARK partnership interests not held by Southwestern. Subject to approval by the
Federal Energy Regulatory  Commission,  NOARK will be converted to an interstate
pipeline and be operated with Ozark as an integrated system.

     In addition  to its  purchase  of Ozark,  Enogex will fund the  integration
project and an expansion of the  combined  system at an estimated  cost of $15.0
million.  The two pipelines  currently have a minor  interconnection  and run in
general   proximity   to  each   other  in  western   Arkansas,   but  a  larger
interconnecting pipeline and compression will be constructed to enable the Ozark
line in  Oklahoma  to serve as the supply  line for both  NOARK and  Ozark.  The
combined pipelines will have capacity of approximately 330 MMcfd. The integrated
system is expected to be  operational  in late 1998.  After the  integration  is
complete,  Southwestern  will have a 25%  interest in the  expanded  project and
Enogex will have a 75% interest.

Competition

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

     NOARK currently competes with two interstate pipelines, one of which is 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 has been strong and has resulted in NOARK transporting

                                       12





gas for third parties at rates below the maximum tariffs presently allowed.  The
planned  integration with Ozark will provide the Company's  pipeline  operations
with increased supplies to transport to both local markets and markets served by
the three  major  interstate  pipelines  that  NOARK  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 the integration of
NOARK and Ozark 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 existng 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.   While  some
regulatory uncertainty remains, Order No. 636 may ultimately enhance the ability
of the  Company to market  natural  gas,  although  it may also  create  greater
competition for the Company.

     The  operations of NOARK are currently  regulated by the APSC. The APSC has
established a maximum  transportation  rate of approximately $.285 per dekatherm
based on NOARK's original construction cost estimate of $73 million. The planned
integration  of NOARK with Ozark will result in an  interstate  pipeline  system
subject to FERC  regulations and FERC approved  tariffs.  A filing was made with
the FERC on March 5, 1998,  seeking  approval  for the  acquisition  of Ozark by
Enogex  and the  integration  of NOARK and Ozark.  The APSC will no longer  have
jurisdiction over NOARK's  transportation rates and services once the integrated

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.

                                       13






     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  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  170 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  near the
Company's headquarters in a growing part of Fayetteville,  Arkansas. 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
which 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,  1997,  the  Company  had 705  employees,  99 of whom are
represented under a collective bargaining  agreement.  The Company believes that
its relations with its employees are good.

     No individually  significant  discovery or other major favorable or adverse
event has occurred since December 31, 1997.

     During 1997,  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 1997 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 May,  1996,  a lawsuit  was filed  against  the  Company  involving  the
disputed  ownership of overriding  royalty  interests in a number of oil and gas
properties. In a related matter, a purported class action suit was filed against
the Company in May, 1996 on behalf of royalty owners alleging  improprieties  in
the  disbursement  of royalty  proceeds.  The  Company  feels  these  claims are
substantially without merit and intends to vigorously contest the claims brought
in each matter.  While the amount of the potential  claims is significant in the
aggregate,  management believes, based on its investigation,  that the Company's
ultimate liability,  if any, will not be material to its consolidated  financial
position or results of operations.

     The  Company  and its  subsidiaries  are  involved  in various  other legal
proceedings  arising in the ordinary  course of  business.  While the outcome of
lawsuits or other  proceedings  cannot be predicted with  certainty,  management
expects  these  matters  will  not  have  a  material   adverse  effect  on  the
consolidated financial position or results of operations 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, 1997, to a vote of security holders, through the solicitation
of proxies or otherwise.

                                     PART II

Item 5.    Market for Registrant's Common Equity and Related Stockholder Matters

     Shareholder  Information on page 46 and "Common Stock Statistics"  included
in the  Company's  Financial  and  Operating  Statistics  on page 44 of the 1997
Annual  Report to  Shareholders  (filed as Exhibit 13 to this filing) are hereby
incorporated by reference for  information  concerning the market for and prices
of the Company's Common Stock,  the number of  shareholders,  and cash dividends
paid.

     The terms of  certain  of the  Company's  long-term  debt  instruments  and
agreements impose restrictions on the payment of cash dividends. At December 31,
1997,  $129.1  million of retained  earnings was  available  for payment as cash
dividends.  These covenants generally limit the payment of dividends in a fiscal
year to the total of net  income  plus $20.0  million  less  dividends  paid and
purchases,  redemptions  or retirements of capital stock during the period since
January 1, 1990. Dividends totaling $5.9 million were paid during 1997.

     The Company paid  dividends at an annual rate of $.24 per share in 1997 and
1996.  While the Board of  Directors  intends to continue the practice of paying
dividends quarterly, amounts and dates of such dividends as may be declared will
necessarily  be  dependent  upon  the  Company's  future  earnings  and  capital
requirements.
