                                     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

<PAGE>



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

<PAGE>



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.

     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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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
system is placed in service.

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

<PAGE>




     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.

</TABLE>

     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.

                            TO GAS PURCHASE CONTRACT


The undersigned  parties,  in consideration  of the mutual  covenants  contained
herein,  hereby agree to amend, as described  below,  the gas purchase  contract
("Contract")  dated  October  1,  1990  between  Arkansas  Western  Gas  Company
("Buyer")  for the  account of  Associated  Natural Gas  Company,  a division of
Arkansas Western Gas Company, and SEECO, Inc. ("Seller").

         1. The phrase  "Contract Annual Quantity" shall be changed to "Contract
Annual Volume" wherever it appears throughout the Contract.

         2. Section 2(B) shall be deleted in its entirety and replaced  with the
            following:

                  (B) It is  understood  that Seller shall deliver to Buyer on a
                  daily basis the quantity  requested by Buyer up to the Maximum
                  Daily Quantity. Should Buyer desire a daily quantity in excess
                  of  such   quantities,   Seller  shall  advise  Buyer  of  the
                  availability or nonavailability of such gas and, if available,
                  when   deliveries  can  commence.   However,   notwithstanding
                  anything  contained in this contract,  Buyer's receipts of gas
                  hereunder shall fluctuate only to the extent such fluctuations
                  are  required by the demands of Buyer's  utility  customers in
                  northeast Arkansas and southeast  Missouri.  Seller shall have
                  no  obligation  to deliver gas to Buyer under this contract to
                  be used  for  resale  to  third  parties  other  than  Buyer's
                  northeast  Arkansas and southeast  Missouri utility customers.
                  Buyer shall take gas hereunder at monthly rates which match as
                  closely as  reasonably  possible  Buyer's  historical  monthly
                  takes under this contract.

         3. Section 6(A) shall be deleted in its entirety and replaced  with the
            following:

                  (A) Subject to the provisions hereinafter set forth, the price
                  payable   hereunder  shall  be  the  price  contained  in  the
                  currently effective contract pricing schedule attached to this
                  contract.  The first such contract  pricing  schedule shall be
                  effective  October 1, 1997.  Each time the price payable under
                  this contract is redetermined, a new contract pricing schedule
                  which identifies the  redetermined  price shall be attached to
                  this  contract,  and shall  supersede  the  previous  contract
                  pricing schedule.

         4. Section (A) (c) of the General Terms and Conditions shall be deleted
            in its entirety and replaced with the following:

                  (c)The  volume  of gas  shall  be  measured  at each  Point of
                  Delivery  by  orifice   meters   installed  and  operated  and
                  computations made as prescribed in the latest accepted version
                  of the  American Gas  Association  Gas  Measurement  Committee

         incurred by the Employee as a result of such  termination of employment

         or disputing  any such  termination  or in seeking to obtain or enforce
         any right or benefit  provided  to the  Employee by this  Agreement  or
         under  any  other  plan,  program  or  arrangement  of the  Company  or
         agreement with the Company),  as and when such fees and expenses become
         due.
                  (iii) The  Employee  shall not be  required  to  mitigate  the

other payment or the value of any benefit  received in connection  with a Change
in Control or the  termination  or the  Employee's  employment  pursuant to this
Agreement or any plan,  agreement or other  arrangement  between the Company and
the  Employee  (or any  member  of  Company's  affiliated  group as such term is

                                       13

Section  1504(b)  thereof) would result in the imposition of an excise tax under
Section  4999 of the Code,  the payment  hereunder  may, at the  election of the
Employee,  be reduced by the amount  necessary to prevent the imposition of such
excise tax. The Company  shall  engage tax counsel  selected by the Employee and
reasonably  acceptable  to the  Company to advise  the  Employee  regarding  any
potential  excise tax  liability  under  Section  4999 of the Code and as to any
benefit or detriment to the Employee of making the reduction  election  provided

of such tax counsel and other experts.
                  6. Payment Obligations  Absolute.  The Company's obligation to
pay the  Employee  the amounts  provided  for  hereunder  shall be absolute  and
unconditional and shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim,  recoupment, defense or other right which
the  Company  may  have  against  him or  anyone  else  and,  including  without
limitation,  any  defense  or claim  based on a breach  by the  Employee  of the
covenants  contained herein.  All amounts payable by the Company hereunder shall
be paid without  notice or demand.  Except as  expressly  provided  herein,  the
Company  waives all rights which it may now have or may hereafter have conferred
upon it, by statute or otherwise, to amend, terminate, cancel or

                                       14

<PAGE>



rescind this Agreement in whole or in part.  Subject to the right of the Company
to seek  arbitration  under  Section  10 hereof and  recover  any  payment  made
hereunder,  each and every payment made hereunder by the Company shall be final,
and the Company  shall not seek to recover all or any part of such  payment from
the  Employee  or from  whomsoever  may be  entitled  thereto,  for  any  reason
whatsoever.
                  7.  Covenant Not to Solicit.
                  (i)  In the event the Employee's employment is
terminated  by the Company  pursuant to Section  3(iv) hereof or by the Employee
pursuant to Section 4 hereof,  the Employee agrees during the three-year  period
following the Termination Date not to:
                  (a) offer employment to any officer or employee of the Company
         or any  subsidiary or  affiliated  company of the Company or attempt to
         induce any such  officer or employee to leave the employ of the Company
         or any subsidiary or affiliated company of the Company; or
                  (b) attempt to persuade or induce, or persuade or induce,  any
         officer,  director,  agent, customer, client or supplier of the Company
         or any  subsidiary or affiliated  company of the Company to discontinue
         his  or  her  relationship  with  the  Company  or  any  subsidiary  or
         affiliated company of the Company.
                  (ii) In the event of any breach of the foregoing covenant, the
Employee acknowledges that the Company's remedy at

                                       15

law is inadequate and that the Company shall be entitled to seek
injunctive relief.
                  8.  Successors; Binding Agreement.
                  (i)  This  Agreement  shall  be  binding  upon  any  successor
(whether direct or indirect, by purchase, merger, consolidation,  liquidation or
otherwise)  to all or  substantially  all of the business  and/or  assets of the
Company. Additionally, the Company shall require any such successor expressly to
agree to assume and to assume all of the  obligations  of the Company under this
Agreement  upon  or  prior  to  such  succession  taking  place.  A copy of such
assumption and agreement  shall be delivered to the Employee  promptly after its
execution  by the  successor.  Failure of the Company to obtain  such  agreement
prior to the  effectiveness  of any such  succession  shall be a breach  of this
Agreement and, as a result of such breach, the Company shall pay to the Employee
the  benefits as  provided in Section 5 hereof as if the Company had  terminated
the  Employee's  employment  on  the  date  on  which  such  succession  becomes
effective,  without Cause, upon a Change in Control.  As used in this Agreement,
"Company"  shall mean the Company as  hereinbefore  defined and any successor to
its business and or assets as aforesaid,  whether or not such successor executes
and delivers the agreement provided for in this Section 8(i).
                  (ii)  This  Agreement  is  personal  to the  Employee  and the
Employee may not assign or transfer any part of his rights or duties  hereunder,
or any compensation due to him hereunder, to

                                       16

<PAGE>



any other person,  except that this Agreement  shall inure to the benefit of and
be enforceable by the Employee's personal or legal  representatives,  executors,
administrators,  heirs,  distributees,  devises,  legatees or beneficiaries.  No
payment  pursuant to any will or the laws of descent and  distribution  shall be
made hereunder  unless the Company shall have been furnished with a copy of such
will and/or such other evidence as the Board may deem necessary to establish the
validity of the payment.
                  9.  Modification;  Waiver. No provisions of this Agreement may
be modified, waived or discharged unless such waiver,  modification or discharge
is agreed to in a writing signed by the Employee and such director or officer as
may be specifically  designated by the Board.  Waiver by any party of any breach
of or failure to comply with any provision of this  Agreement by the other party
shall not be construed as, or constitute, a continuing waiver of such provision,
or a waiver of any  other  breach  of, or  failure  to  comply  with,  any other
provision of this Agreement.
                  10.  Arbitration of Disputes.
                  (i) Any  disagreement,  dispute,  controversy or claim arising
out of or relating to this Agreement or the  interpretation  or validity  hereof
shall be settled exclusively and finally by arbitration except that in the event
of the  Employee's  breach of the covenant  contained  in Section 7 hereof,  the
Company shall be entitled to seek  injunctive  relief  pursuant to Section 7(ii)
hereof. It is specifically understood and agreed that any

                                       17

<PAGE>



disagreement,  dispute or  controversy  which  cannot be  resolved  between  the
parties,  including without limitation any matter relating to the interpretation
of this Agreement, may be submitted to arbitration irrespective of the magnitude
thereof,  the amount in  controversy  or whether such  disagreement,  dispute or
controversy otherwise would be considered  justiciable or ripe for resolution by
a court or arbitral tribunal.
                  (ii) The arbitration shall be conducted in accordance with the
Commercial   Arbitration  Rules  (the  "Arbitration   Rules")  of  the  American
Arbitration Association (the "AAA").
                  (iii) The arbitral  tribunal shall consist of one  arbitrator.
The parties to the  arbitration  jointly shall directly  appoint such arbitrator
within 30 days of  initiation of the  arbitration.  If the parties shall fail to
appoint such arbitrator as provided above, such arbitrator shall be appointed by
the AAA as  provided  in the  Arbitration  Rules and  shall be a person  who (a)
maintains  his  principal  place  of  business  within  30  miles of the City of
Fayetteville,   Arkansas,  and  (b)  has  had  substantial  experience  (whether
practical  or  academic)  in mergers and  acquisitions  or, if no such person is
available,  in employee benefits. The Company shall pay all of the fees, if any,
and expenses of such arbitrator.
                  (iv) The arbitration shall be conducted within 30 miles of the
City of  Fayetteville,  Arkansas  or in such other city in the United  States of
America as the parties to the dispute may designate by mutual written consent.

arbitration,  each party  thereto or its legal  counsel  shall have the right to
examine its witnesses and to cross-examine  the witnesses of any opposing party.
No evidence of any  witness  shall be  presented  unless the  opposing  party or
parties shall have the opportunity to cross-examine such witness,  except as the
parties to the dispute otherwise agree in writing or except under  extraordinary
circumstances where the interests of justice require a different procedure.
                  (vi) Any decision or award of the arbitral  tribunal  shall be
final and binding upon the parties to the  arbitration  proceeding.  The parties
hereto hereby waive, to the extent  permitted by law, any rights to appeal or to
seek review of such award by any court or  tribunal.  The parties  hereto  agree
that the arbitral award may be enforced  against the parties to the  arbitration
proceeding  or their assets  wherever they may be found and that a judgment upon
the arbitral award may be entered in any court having jurisdiction.
                  (vii)  Nothing  herein  contained  shall be deemed to give the
arbitral  tribunal  any  authority,  power,  or right to alter,  change,  amend,
modify, add to, or subtract from any of the provisions of this Agreement.

combination  with the  Company or an  acquisition  of equity  securities  of the
Company,  the Board of Directors of the Company (hereinafter called the "Board")
believes it  imperative  that the Company and the Board be able to rely upon the
Employee to continue in his position, and that the Company and the Board be able
to  receive  and rely  upon  his  advice,  if they  request  it,  as to the best
interests of the Company and its shareholders,  without concern that he might be

                  Notwithstanding Subparagraphs (a) through (d) of this
Paragraph (ii), a Change in Control shall not occur by reason of
any event which would otherwise constitute a Change in Control if, immediately
after the occurrence of such event, individuals who are Acquiring Persons and

                  (iii) The Employee may not be terminated  for Cause unless and
until a notice of intent to  terminate  the  Employee's  employment  for  Cause,
specifying the particulars of the conduct of the Employee  forming the basis for

majority of the Board finds,  after reasonable notice to the Employee (but in no

Employee's death, whether or not during the Contract Period.

         full base salary earned by the Employee  through the  Termination  Date
         and unpaid at the Termination  Date,  calculated at the highest rate of
         base salary in effect at any time during the twelve months  immediately
         preceding  the  Termination  Date,  (II) the amount of any base  salary
         attributable  to vacation  earned by the  Employee but not taken before
         the  Termination  Date,  (III)  any  annualized  bonus  accrued  to the

pursuant  to Section  3(ii) or 3(iv)  hereof,  or by the  Employee  pursuant  to
Section 4 hereof,  the  employee  shall be  entitled  to receive  the  following
payments and benefits:
                  (a) The  Company  shall  maintain in full force and effect for
         the   Employee's   continued   benefit  all  life,   medical,   dental,
         prescription drug and long- and short-term  disability plans,  programs
         or arrangements, whether group or individual, in which the Employee was
         entitled  to  participate  at any time  during the twelve  month-period
         prior to the Termination Date, until the earliest to occur of (I) three
         years after the Termination  Date; (II) the Employee's  death (provided
         that benefits payable to his beneficiaries shall not terminate upon his
         death);  or (III)  with  respect  to any  particular  plan,  program or
         arrangement,  the  date  he  is  afforded  a  comparable  benefit  at a
         comparable cost to the Employee by a subsequent employer.  In the event
         that  the  Employee's  participation  in  any  such  plan,  program  or
         arrangement of the Company is prohibited,  the Company shall

                                       14

<PAGE>

         arrange to provide the Employee with benefits substantially similar to
         those which the  Employee  is  entitled  to receive  under  such  plan,
         program or arrangement for such period.                                
                  (b) The Company  shall pay to the  Employee all legal fees and
         expenses (including legal fees and expenses incurred in connection with
         an  arbitration  proceeding  engaged in  pursuant to Section 10 hereof)
         incurred by the Employee as a result of such  termination of employment
         (including all such fees and expenses,  if any,  incurred in contesting
         or disputing  any such  termination  or in seeking to obtain or enforce
         any right or benefit  provided  to the  Employee by this  Agreement  or
         under  any  other  plan,  program  or  arrangement  of the  Company  or
         agreement with the Company),  as and when such fees and expenses become
         due.
                  (iii) The  Employee  shall not be  required  to  mitigate  the
amount of any payment or benefit provided for in this Section 5 by seeking other
employment or otherwise.
                  (iv) The amount of any payment or benefit provided for in this
Section 5 shall not be reduced by any  compensation,  benefits or other  amounts

<PAGE>
                  (v) In the event that any payment hereunder, together with any
other payment or the value of any benefit  received in connection  with a Change
in Control or the  termination  or the  Employee's  employment  pursuant to this
Agreement or any plan,  agreement or other  arrangement  between the Company and
the  Employee  (or any  member  of  Company's  affiliated  group as such term is
defined in Section 1504 of the Code,  without regard to Section 1504(b) thereof)
would result in the  imposition of an excise tax under Section 4999 of the Code,
the payment  hereunder  may, at the election of the Employee,  be reduced by the
amount necessary to prevent the imposition of such excise tax. The Company shall
engage tax counsel  selected by the Employee and  reasonably  acceptable  to the
Company to advise the Employee  regarding  any  potential  excise tax  liability
under  Section  4999 of the  Code  and as to any  benefit  or  detriment  to the
Employee of making the reduction election provided for hereunder.  In making the
determinations  required  in  order  to give  the  advice  contemplated  by this
Paragraph  (v),  tax counsel may rely on benefit  consultants,  accountants  and
other  experts.  The  Company  agrees to pay all fees and  expenses  of such tax
counsel and other experts.

pay the  Employee  the amounts  provided  for  hereunder  shall be absolute  and
unconditional and shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim,  recoupment, defense or other right which
the  Company  may  have  against  him or  anyone  else  and,  including  without
limitation,  any  defense  or claim  based on a breach  by the  Employee  of the
covenants  contained herein.  All amounts payable by the Company hereunder shall
be paid without  notice or demand.  Except as  expressly  provided  herein,  the
Company  waives all rights which it may now have or may hereafter have conferred
upon it, by statute or otherwise,  to amend,  terminate,  cancel or rescind this
Agreement  in whole or in part.  Subject  to the  right of the  Company  to seek
arbitration under Section 10 hereof and recover any payment made hereunder, each
and every payment made hereunder by the Company shall be final,  and the Company
shall not seek to recover all or any part of such  payment  from the Employee or
from whomsoever may be entitled thereto, for any reason whatsoever.
                  7.  Covenant Not to Solicit.
                  (i) In the event the  Employee's  employment  is terminated by
the Company pursuant to Section 3(iv) hereof or by

                                       17

<PAGE>

the  Employee  pursuant  to Section 4 hereof,  the  Employee  agrees  during the
three-year period following the Termination Date not to:
                  (a) offer employment to any officer or employee of the Company
         or any  subsidiary or  affiliated  company of the Company or attempt to
         induce any such  officer or employee to leave the employ of the Company
         or any subsidiary or affiliated company of the Company; or
                  (b) attempt to persuade or induce, or persuade or induce,  any
         officer,  director,  agent, customer, client or supplier of the Company
         or any  subsidiary or affiliated  company of the Company to discontinue
         his  or  her  relationship  with  the  Company  or  any  subsidiary  or
         affiliated company of the Company.
                  (ii) In the event of any breach of the foregoing covenant, the
Employee  acknowledges  that the Company's  remedy at law is inadequate and that
the Company shall be entitled to seek injunctive relief.
                  8.  Successors; Binding Agreement.
                  (i)  This  Agreement  shall  be  binding  upon  any  successor
(whether direct or indirect, by purchase, merger, consolidation,  liquidation or
otherwise)  to all or  substantially  all of the 

                                       18

<PAGE>

business and/or assets of the Company.  Additionally,  the Company shall require
any such  successor  expressly  to  agree to  assume  and to  assume  all of the
obligations of the Company under this Agreement upon or prior to such succession
taking place. A copy of such  assumption and agreement shall be delivered to the
Employee  promptly after its execution by the successor.  Failure of the Company
to obtain such agreement prior to the effectiveness of any such succession shall
be a breach of this Agreement and, as a result of such breach, the Company shall
pay to the  Employee  the  benefits  as  provided  in Section 5 hereof as if the
Company  had  terminated  the  Employee's  employment  on the date on which such
succession becomes effective,  without Cause, upon a Change in Control.  As used
in this Agreement,  "Company" shall mean the Company as hereinbefore defined and
any  successor to its business and or assets as  aforesaid,  whether or not such
successor executes and delivers the agreement provided for in this Section 8(i).
                  (ii)  This  Agreement  is  personal  to the  Employee  and the
Employee may not assign or transfer any part of his rights or duties  hereunder,
or any compensation due to him hereunder,  to any other person, except that this
Agreement  shall inure to the benefit of and be  enforceable  by the  Employee's
personal or legal

                                       19

<PAGE>

representatives,   executors,  administrators,   heirs,  distributees,  devises,
legatees  or  beneficiaries.  No  payment  pursuant  to any  will or the laws of
descent and  distribution  shall be made hereunder unless the Company shall have
been  furnished with a copy of such will and/or such other evidence as the Board
may deem necessary to establish the validity of the payment.

                  9.  Modification;  Waiver. No provisions of this Agreement may
be modified, waived or discharged unless such waiver,  modification or discharge
is agreed to in a writing signed by the Employee and such director or officer as
may be specifically  designated by the Board.  Waiver by any party of any breach
of or failure to comply with any provision of this  Agreement by the other party
shall not be construed as, or constitute, a continuing waiver of such provision,
or a waiver of any  other  breach  of, or  failure  to  comply  with,  any other
provision of this Agreement.
                  10.  Arbitration of Disputes.
                  (i) Any  disagreement,  dispute,  controversy or claim arising
out of or relating to this Agreement or the  interpretation  or validity  hereof
shall be settled exclusively and finally by arbitration except that in the event
of the  Employee's  breach of the covenant  contained  in Section 7 hereof,  the
Company 

                                       20

<PAGE>


shall be entitled to seek injunctive relief pursuant to Section 7(ii) hereof. It
is  specifically  understood  and  agreed  that  any  disagreement,  dispute  or
controversy  which  cannot be resolved  between the parties,  including  without
limitation any matter relating to the  interpretation of this Agreement,  may be
submitted to arbitration  irrespective of the magnitude  thereof,  the amount in
controversy or whether such disagreement, dispute or controversy otherwise would
be  considered  justiciable  or  ripe  for  resolution  by a court  or  arbitral
tribunal.
                  (ii) The arbitration shall be conducted in accordance with the
Commercial   Arbitration  Rules  (the  "Arbitration   Rules")  of  the  American
Arbitration Association (the "AAA").
                  (iii) The arbitral  tribunal shall consist of one  arbitrator.
The parties to the  arbitration  jointly shall directly  appoint such arbitrator
within 30 days of  initiation of the  arbitration.  If the parties shall fail to
appoint such arbitrator as provided above, such arbitrator shall be appointed by
the AAA as  provided  in the  Arbitration  Rules and  shall be a person  who (a)
maintains  his  principal  place  of  business  within  30  miles of the City of
Fayetteville,   Arkansas,  and  (b)  has  had  substantial  experience  (whether
practical  or  academic)  in mergers and  acquisitions  or, if no such person is
available,  in employee

                                       21

benefits.  The Company  shall pay all of the fees,  if any, and expenses of such
arbitrator.
                  (iv) The arbitration shall be conducted within 30 miles of the
City of  Fayetteville,  Arkansas  or in such other city in the United  States of
America as the parties to the dispute may designate by mutual written consent.
                  (v) At any oral  hearing of  evidence in  connection  with the
arbitration,  each party  thereto or its legal  counsel  shall have the right to
examine its witnesses and to cross-examine  the witnesses of any opposing party.
No evidence of any  witness  shall be  presented  unless the  opposing  party or
parties shall have the opportunity to cross-examine such witness,  except as the
parties to the dispute otherwise agree in writing or except under  extraordinary
circumstances where the interests of justice require a different procedure.
                  (vi) Any decision or award of the arbitral  tribunal  shall be
final and binding upon the parties to the  arbitration  proceeding.  The parties
hereto hereby waive, to the extent  permitted by law, any rights to appeal or to
seek review of such award by any court or  tribunal.  The parties  hereto  agree
that the arbitral award may be enforced  against the parties to the  arbitration
proceeding  or their assets  wherever they may be found

                                       22

<PAGE>
and that a judgment  upon the arbitral  award may be entered in any court having
jurisdiction.
                  (vii)  Nothing  herein  contained  shall be deemed to give the
arbitral  tribunal  any  authority,  power,  or right to alter,  change,  amend,
modify, add to, or subtract from any of the provisions of this Agreement.
                  11.  Notice.   All  notices,   requests,   demands  and  other

                  funded through a Trust;

                           (ii)     A stock option and incentive bonus plan;

                  by a reputable  insurance company authorized to do business in
                  the State of Arkansas,  which plan provides  coverage for each
                  such officer and employee of SWEN and their immediate  family;
                  and

         plan and/or insurance policy, and shall continue as such participant as

         benefits)  shall vest  indefeasibly  simultaneously  with the  creation

         Severance  Agreement shall be deemed to refer to the Term of Employment
         hereunder.  The Executive Severance Agreement is hereby referred to for
         a  full  recital  of the  terms  and  provisions  thereof  and by  this
         reference  is made a part  hereof.  To the extent there is any conflict
         between  the terms of this  Agreement  and the  terms of the  Executive
         Severance Agreement, the terms of this Agreement shall control.

                                      -4-

         EMPLOYEE shall have the right, at his option, to either (i) continue in

         above, employment shall be on such terms and conditions as are mutually
         acceptable  and agreed upon by the  EMPLOYEE and SWEN.  The  EMPLOYEE's
         termination  rights or conditions shall thereafter be as agreed upon by
         contract  between the EMPLOYEE and SWEN or as set forth by SWEN Company
         policies.  If the  EMPLOYEE  elects  option (ii) above,  the  Severance
         Payment  shall be paid to the  EMPLOYEE  no later than the  Termination
         Date. For the purposes of this Agreement,  the term "Termination  Date"
         shall mean the date that is five (5)  business  days after the EMPLOYEE
         gives notice to SWEN of his election to terminate his employment.

         3.  Vacation:  During the Term of  Employment,  the  EMPLOYEE  shall be
entitled to sick leave,  holidays and an annual  4-week  vacation,  during which

SWEN.

         4. Successors;  Binding Agreement: The assignability and binding nature

obligation under such definitive agreement.  Such definitive agreement is in the
form of the Asset  Purchase and Sale Agreement  attached  hereto as Exhibit "A."
Upon the acquisition of such assets and the  contribution  of EIT to NOARK,  the
Parties agree that NOARK promptly will commence the interconnection of the NOARK
pipeline  system with the Ozark  pipeline  system and the expansion of the NOARK
and Ozark pipeline systems as specified in Exhibit J.

         4.  Acquisition  of Searcy  Gathering  Assets . EAPC shall use its best
reasonable  efforts to enter into a definitive  agreement with Warren  Petroleum
Company,  L.P. for the acquisition of the Searcy  Gathering  Assets described on
Exhibit  "B,"  attached  hereto  and  made a part  hereof.  In the  event of the
execution of such agreement,  EAPC will use its best reasonable efforts to close
such acquisition. Upon the closing of such acquisition, EAPC will, upon approval
by SWPL,  which approval shall not be  unreasonably  withheld,  contribute  such
Searcy  Gathering Assets to OGG L.L.C. and EAPC's capital account in NOARK shall
be credited with an amount equal to all amounts paid by EAPC for the purchase of
the Searcy  Gathering  Assets.  Nothing in this Agreement  shall be construed to
confer upon SWPL, SWN or NOARK, or their respective  successors and assigns, any
right,  benefit or obligation under such definitive  agreement.  Such definitive
agreement  shall be in a form  substantially  similar to the Asset  Purchase and
Sale  Agreement  attached  hereto  as  Exhibit  "C."  Further,  nothing  in this
Agreement will be construed to obligate NOARK, SWPL or SWN to accept or agree to
the  contribution  of the  Searcy  Gathering  Assets  unless  and until SWPL has
approved such contribution, which approval shall not be unreasonably withheld.

         5. NGSC.  There currently  exists various  disputes between SWN and its
Affiliates and SEMCO and its Affiliates regarding, among other matters, NGSC. On
or before the acquisition by EAPC of all of the SEMCO  Interests,  SWN, SWPL and
any  of  their  appropriate  Affiliates  shall  execute  a  Mutual  Release  and
Settlement  Agreement between SWN, SWPL and any of their appropriate  Affiliates
and  SEMCO  Energy,  Inc.  and any of its  appropriate  Affiliates,  in the form
attached hereto as Exhibit "D."

         6.  Acquisition  and Merger of AWP. SWN shall convey to SWPL all of the
capital stock of AWP, and SWPL shall cause AWP to be merged into AWP L.L.C.  The
Parties  recognize,  however,  that FERC  authorization may be required prior to
consummating  such merger.  Upon the Closing,  SWPL agrees to file with FERC for
such  authorization and to use its best reasonable  efforts to diligently pursue
and obtain such  authorization.  Such filing may be made in conjunction with the
filings  contemplated under Section 10, and the fees and expenses of such filing
shall be borne by EAPC.  Upon  receipt of such  authorization  from  FERC,  SWPL
agrees to cause AWP to be merged into AWP L.L.C., and immediately  thereafter to
contribute and assign all of the ownership  interests in AWP L.L.C. to NOARK. In
the event such FERC  authorization  is not  received by the closing of the Ozark
acquisition  contemplated  in Section 3 above,  then SWPL  shall  convey to EAPC
seventy-

                                       7

five  percent  (75%) of all  outstanding  capital stock of AWP, free and
clear of all Liens. Following such contribution or sale of stock, as applicable,
all of the assets of AWP L.L.C.,  or AWP, as  applicable,  shall be those assets
described on Exhibit "E." In the event of such purchase of seventy-five  percent
(75%) of AWP's  stock,  EAPC and SWPL  shall  contribute  all of AWP's  stock to
NOARK.  In addition,  within ten (10) days  following such  contribution  of the
ownership  interests of AWP L.L.C.  into NOARK,  or the  contribution  of all of
AWP's stock into NOARK,  as  applicable,  EAPC shall pay to SWPL  $1,575,000.00.
Upon such  contribution  and payment,  SWPL's capital  account in NOARK shall be
credited with  $525,000.00 and EAPC's capital account in NOARK shall be credited
with  $1,575,000.00,  as a result of the  contribution  of AWP L.L.C. or AWP, as
applicable, into NOARK.

         7.  Closing.  The  Closing  of the  transaction  contemplated  by  this
Agreement  shall take place at the  offices of Hall,  Estill,  Hardwick,  Gable,
Golden & Nelson, 320 S. Boston Ave., Suite 400, Tulsa, Oklahoma or at such other

                  (e) Each of the Parties  will  execute and deliver  such other
         documents as may be required to  accomplish  the items set forth in (a)

         8. Ownership in NOARK, and Status of Capital Accounts.

                  (a) Upon the Closing  referenced in Section 7 above, EAPC will
         elect to convert all of the Prudential  Interest to general partnership
         interests in NOARK  except for a one percent  (1%) limited  partnership
         interest in NOARK,  and the ownership  interests in NOARK shall then be
         as set forth in the  Amended  and  Restated  Partnership  Agreement  of
         NOARK,  the form of which is attached as Exhibit  "F." Such  conversion
         will be made by EAPC  executing  the  Election  to  Convert in the form

                  (b) Upon the closing,  and following the contribution to NOARK
         of the assets  described  in Section  7(b) above,  the  balances of the

         Schedule  4.1 to the  Amended and  Restated  Partnership  Agreement  of
         NOARK,  the form of which is attached  hereto as Exhibit "F".  Further,
         these balances are also inclusive of the yield maintenance amounts paid
         by NOARK and funded by SEMCO and SWPL discussed in Section 9(c) below.

                  (c) Allocations of NOARK  partnership  income or loss to SEMCO
         will be based upon the actual  closing of books on the day its interest
         is sold to EAPC.

         9. NOARK Debt.

                  (a) The Parties  acknowledge that the execution of the Amended
         and Restated  Partnership  Agreement  of NOARK in the form  attached as
         Exhibit "F", and certain of the other actions  contemplated  under this
         Agreement,  require the consent of the lenders under the loan documents
         pursuant  to which  the  NOARK  Debt  described  under  item (a) of the
         definition of NOARK Debt was incurred.  Accordingly,  the Parties agree
         that the Closing shall not occur unless all such  consents  required to
         be obtained from such lenders are in fact obtained.

                  (b) The Parties acknowledge that all loans from SEMCO and SWPL
         to NOARK have been  converted  to capital  contributions  to NOARK.  As
         such, those loans are no longer in force or effect, and NOARK no longer
         has any  obligation  to repay such loans.  Further,  the  Parties  also
         acknowledge that the capital account balances set forth on Schedule 4.1
         to the Amended and Restated Partnership Agreement of NOARK, the form of
         which is attached  hereto as Exhibit "F",  reflect the inclusion of the
         conversion of such loans to capital contributions.

                  (c) The Parties  acknowledge that concurrent with the Closing,
         Enogex is making a loan to NOARK in an amount necessary to pay off that
         portion of the NOARK Debt  described in item (b) of the  definition  of
         NOARK Debt. The general terms of such loan from Enogex are described on
         Exhibit "L." The Parties  further  acknowledge  that (i) in  connection
         with the pay off of such portion of the NOARK Debt, NOARK is making the
         yield maintenance  payments to Prudential to enable the payment of such
         portion of the NOARK Debt and SEMCO and SWPL shall have  contributed to
         NOARK amounts equal to such yield maintenance  payments,  and ii) SEMCO
         and SWPL shall be entitled to any tax deductions or other benefits that
         may arise from the  respective  amounts each  contributed  to NOARK for
         such yield maintenance payments made by NOARK.

                  (d)  Concurrent  with  the  Closing,  EAPC  shall  assume  all
         obligations  of SEMCO  under that  portion of the NOARK Debt  described
         under item (a) of the definition of NOARK Debt.

         above filings.

                  (b) The Parties  recognize that certain  filings under the HSR

         system with the Ozark pipeline  system,  and the expansion of the NOARK
         and Ozark  pipeline  systems as specified in Exhibit J attached  hereto
         which  interconnection  and expansion will not occur until after EAPC's
         contribution of the ownership interests in EIT to NOARK contemplated by
         Section 3 above. Such  contributions  shall be made by EAPC immediately
         prior to the time the amounts under this  subparagraph (c) are required
         to be paid by NOARK,  and shall be used by NOARK to make such payments.
         EAPC's  Capital  Account  under the  Amended and  Restated  Partnership
         Agreement  of NOARK  (the form of which is  attached  hereto)  shall be

                  amounts  payable  by EIT  under  the  terms  of the  contracts
                  described in (d) above will have been properly and timely paid
                  except for such amounts as are then being currently paid prior
                  to delinquency in the ordinary  course of business.  Except as
                  set  forth on the  Ozark  Disclosure  Schedule,  all  material
                  amounts then payable by  third-parties  under the terms of the
                  agreements described in (iv) above will be properly and timely
                  paid to EIT.

                           (vi) At the  Contribution  Time,  EIT shall have good
                  title to all of the Ozark  Pipeline and the other  properties,
                  contracts  and assets,  real and personal of EIT, all of which
                  will  then be free of all  Liens,  except  for (i)  liens  for
                  current  taxes  and  assessments  that  are  not  yet  due and
                  payable; (ii) mechanics', warehousemen's, landlords' and other

                  inquiry, the equipment related to the Ozark Pipeline will have
                  been maintained in satisfactory  operating  condition and will
                  be  capable  of  being  used  in the  operation  of the  Ozark
                  Pipeline  in the  manner  in which  it has  been  historically
                  operated without present need for repair or replacement except

                  licenses and other  authorizations  ("Environmental  Permits")
                  relating to the Ozark Pipeline,  which are then required under
                  applicable  laws  relating to pollution or  protection  of the
                  environment, including laws relating to emissions, discharges,
                  releases or threatened  releases of pollutants,  contaminants,
                  or  hazardous  or toxic  materials or wastes into ambient air,
                  surface water, ground water, or land, or otherwise relating to
                  the manufacture,  processing,  distribution,  use,  treatment,
                  storage,  disposal,  transport,  or  handling  of  pollutants,
                  contaminants,  or hazardous or toxic  materials or wastes into
                  ambient air, surface water, ground water or land, or otherwise
                  relating to the manufacture,  processing,  distribution,  use,
                  treatment,   storage,  disposal,   transport  or  handling  of
                  pollutants,  contaminants  or hazardous or toxic  materials or
                  wastes (collectively, the "Environmental Laws").

                           (b) EIT and the Ozark  Pipeline  will be in  material
                  compliance with all terms and conditions of such Environmental
                  Permits   and  with  all  other   limitations,   restrictions,
                  conditions,     standards,     prohibitions,     requirements,
                  obligations,   schedules  and  timetables  contained  in  such
                  Environmental Laws or contained in any regulation, code, plan,
                  order,  decree,  judgment  or notice or demand  letter  from a
                  governmental entity issued,  entered,  promulgated or approved
                  thereunder  as  they  will  then  apply  to EIT  or the  Ozark
                  Pipeline.

                           (c) Enogex,  EAPC or EIT will not have  received  any
                  notification  from any  governmental  authority  or any  other
                  person that any of the current or former properties, assets or
                  operations  of EIT or the  Ozark  Pipeline  will then be in or
                  claimed  to  be  in  material   violation  of  any  applicable
                  Environmental Laws.

                           (d) There  will be no  material  civil,  criminal  or
                  administrative action, suit, demand, claim, hearing, notice of
                  violation, investigation,  proceeding, notice or demand letter
                  from a  governmental  entity  pending  or  threatened  against
                  Enogex,  EAPC  or  EIT  with  respect  to the  Ozark  Pipeline
                  claiming  a  violation   of,  or  any  probable  or  potential
                  violation of, any applicable Environmental Laws.

                           (e) To the best of their knowledge after due inquiry,
                  there  will  be  no  past  or  present   events,   conditions,
                  circumstances,  activities,  practices,  incidents, actions or
                  plans,   which  will  interfere  with,  or  prevent   material
                  compliance  or  continued   material   compliance   with,  the
                  Environmental Laws or with any regulation,  code, plan, order,
                  decree, judgment, injunction, notice or demand letter from any
                  governmental entity issued,  entered,  promulgated or approved
                  thereunder,  or which  will give rise to any legal  liability,
                  including,    without   limitation,    liability   under   the
                  Comprehensive   Environmental   Response,   Compensation   and
                  Liability  Act  ("CERCLA")  or similar state or local laws, or
                  otherwise form the basis of any claim,  action,  demand, suit,
                  proceeding,  hearing,  notice of violation,  or  investigation
                  which  would be  materially  adverse,  individually  or in the
                  aggregate, to EITbased on or

                  resulting  from the conduct of the business of EIT,  including
                  the   ownership   and   operation   of  the  Ozark   Pipeline,
                  manufacture,   processing,   distribution,   use,   treatment,
                  storage,  disposal,  transport or handling,  or the  emission,
                  discharge, release or threatened release into the environment,
                  of any pollutant,  contaminant,  chemical, or industrial toxic
                  or  hazardous  material,  substance  or waste.  To the best of
                  their  knowledge  after due inquiry,  no release,  emission or
                  discharge into the environment of any hazardous  substance (as
                  that term is currently  defined under CERCLA or any applicable
                  analogous  state  law)  will  have  occurred  or will  then be
                  occurring  in  connection  with the conduct of the business of
                  EIT,  including  the  ownership  and  operation  of the  Ozark
                  Pipeline, as a result of which release, emission or discharge,
                  individually  or in the  aggregate,  there would be a material
                  adverse  affect on EIT. To the best of their  knowledge  after
                  due inquiry,  the real property then owned or leased by EIT or
                  upon which EIT will then have a  right-of-way  will contain no
                  spill,  deposit or discharge of any  hazardous  substance  (as
                  that  term is then  defined  under  CERCLA  or any  applicable
                  analogous  state law), as a result of which spill,  deposit or
                  discharge,  individually or in the aggregate, there would be a
                  material adverse effect on EIT or the Ozark Pipeline.

                           (x) All  material  taxes based  upon,  measured by or
                  imposed  with  respect to EIT or the prior  owner of the Ozark
                  Pipeline  (if EIT  acquires  the assets of the Ozark  Pipeline
                  System) which are  attributable to the period on or before the
                  Contribution  Time will have  been  paid or  deposited  to the
                  extent required to be so paid or deposited.

                           (xi) To the best of their  knowledge,  except  as set
                  forth  on  the  Ozark  Disclosure  Schedule  or in  the  Asset
                  Purchase and Sale Agreement  attached as Exhibit "A," EIT will
                  not  have  any  material  liabilities  or  obligations  of any
                  nature,  whether absolute,  accrued,  contingent or otherwise,
                  and   whether  due  or  to  become  due   (including   without
                  limitation,  any liability for taxes and interest,  penalty or
                  other  charges  payable with respect to any such  liability or
                  obligation).

                           (xii) At the  Contribution  Time, (i) EAPC shall have
                  good title to all of the ownership  interests in EIT, free and
                  clear of all Liens, and all of those ownership interests shall
                  be owned by EAPC  free and  clear of any  security  interests,
                  voting   trusts,   agreements,   proxies,   options  or  other
                  restrictions;  (ii) EIT will have no subsidiaries, no interest
                  in any  partnership  or joint venture and will not hold shares
                  of stock or other ownership interest in any corporation, trust
                  or other  Person;  and (iii)  there will be:  (a) no  existing
                  subscriptions, options, warrants, calls, commitments or rights
                  of any  character to purchase or otherwise  acquire any shares
                  of capital stock or other  securities or interests of EIT; and
                  (b) no contracts,  subscriptions,  options,  warrants,  calls,
                  commitments  or rights to purchase or otherwise  acquire,  any
                  securities or other  interests  that are  convertible  into or
                  exchangeable  for shares of capital stock or other  securities
                  or interests of EIT.

                           (xiii) With  respect to the Asset  Purchase  and Sale

                  Agreement"):

                                    (a) the  employees  of  Ozark  which  are to

                           contribution  of EIT to NOARK,  become  employees  of
                           EAPC (or one of its  Affiliates)  and EAPC (or one of
                           its  Affiliates)  shall bear,  without  reimbursement
                           from  NOARK,  all of the  cost  and  expense  of such
                           employees,  including  the  obligation  to  make  any
                           severance,  termination or other such payments to any
                           of such employees; provided, however, if EAPC (or any
                           of its Affiliates)  utilizes any of such employees in
                           providing  services  to NOARK  (including  any  NOARK
                           Related   Entity)  under  The  Amended  and  Restated
                           Partnership  Agreement  of  NOARK,  then the costs of
                           such  employees in providing  such services  shall be
                           reimbursed by NOARK in accordance with the Accounting
                           Procedures  attached  to such  Amended  and  Restated

                                    (b) EIT will not agree to any  allocation of
                           the  purchase  price  payable  under the terms of the
                           Ozark  Agreement   without  first  obtaining   SWPL's

                           allocation,  which  agreement or approval will not be
                           unreasonably withheld;

                                    (c) Enogex shall be responsible for ensuring
                           that Natural Gas  Clearinghouse  ("NGC") fulfills its
                           obligations   under  that  certain  Imbalance  Makeup
                           Agreement, dated December 15, 1997;

                                    (d) at the  Contribution  Time,  Ozark  will

                           compressor  overhaul schedule and planned maintenance
                           set forth on  Exhibit D of the  Ozark  Agreement  and
                           NOARK will not, from and after the Contribution Time,
                           bear or incur any cost or expense  to perform  any of
                           the  actions  with  respect  to  the  Ozark  Pipeline
                           required  to be  performed  by or at the  expense  of
                           Ozark on such  schedule  prior to the  closing of the

                           (e) To the best of their knowledge after due inquiry,
                  there  will  be  no  past  or  present   events,   conditions,
                  circumstances,  activities,  practices,  incidents, actions or
                  plans,   which  will  interfere  with,  or  prevent   material
                  compliance  or  continued   material   compliance   with,  the
                  Environmental Laws or with any regulation,  code, plan, order,
                  decree, judgment, injunction, notice or demand letter from any
                  governmental entity issued,  entered,  promulgated or approved
                  thereunder,  or which  will give rise to any legal  liability,
                  including,  without  limitation,  liability  under  CERCLA  or
                  similar  state or local laws,  or otherwise  form the basis of
                  any claim, action, demand, suit, proceeding,  hearing,  notice
                  of  violation,  or  investigation  which  would be  materially
                  adverse,  individually  or in the  aggregate,  to  EAPC or the
                  Searcy Gathering Assets based on or resulting from the conduct
                  of the  business of EAPC as it pertains to the  ownership  and
                  operation of the Searcy  Gathering  Assets or the manufacture,
                  processing,  distribution,  use, treatment, storage, disposal,
                  transport or handling, or the emission,  discharge, release or
                  threatened  release into the  environment,  of any  pollutant,
                  contaminant,   chemical,  or  industrial  toxic  or  hazardous
                  material, substance or waste from the Searcy Gathering Assets.
                  To the best of their knowledge after due inquiry,  no release,
                  emission or discharge  into the  environment  of any hazardous
                  substance  (as that term is currently  defined under CERCLA or
                  any applicable analogous state law) will have occurred or will
                  then be  occurring  in  connection  with  the  conduct  of the
                  business of EAPC as it pertains to the ownership and operation
                  of the Searcy Gathering  Assets, as a result of which release,
                  emission or discharge, individually or in the aggregate, there
                  would be a  material  adverse  affect on EAPC.  To the best of
                  their  knowledge  after due inquiry,  the real  property  then
                  owned or leased by EAPC  pertaining  to the  Searcy  Gathering
                  Assets  or upon  which  EAPC  will  then  have a  right-of-way
                  pertaining  to the Searcy  Gathering  Assets  will  contain no
                  spill,  deposit or discharge of any  hazardous  substance  (as
                  that  term is then  defined  under  CERCLA  or any  applicable
                  analogous  state law), as a result of which spill,  deposit or
                  discharge,  individually or in the aggregate, there would be a
                  material  adverse  effect  on  EAPC  or the  Searcy  Gathering
                  Assets.

                           (ix) All  material  taxes based upon,  measured by or
                  imposed  with  respect  to  EAPC   pertaining  to  the  Searcy
                  Gathering  Assets or the prior  owner of the Searcy  Gathering
                  Assets which are  attributable  to the period on or before the
                  Searcy  Contribution  Time will have been paid or deposited to
                  the extent required to be so paid or deposited.

                           (x) To the best of  their  knowledge,  except  as set
                  forth  on the  Searcy  Disclosure  Schedule,  or in the  Asset
                  Purchase and Sale Agreement attached as Exhibit "C," EAPC will
                  not have any material liabilities or obligations pertaining to
                  the Searcy Gathering Assets of any nature,  whether  absolute,
                  accrued, contingent or otherwise, and whether due or to become
                  due (including without limitation, any liability for taxes and
                  interest, penalty or other charges payable with respect to any

                  (i) Brokers.  They have not  employed,  directly or indirectly
         for their  benefit,  any broker or finder or incurred any liability for
         any financial  advisory fees,  brokerage fees,  commissions or finders'
         fees, and no broker or finder has acted directly or indirectly for them
         in  connection  with this  Agreement or the  transactions  contemplated
         hereby.

                  (j)  Material  Fact.  To  the  best  of  their  knowledge,  no
         representation  or warranty in this  Section  11,  contains  any untrue
         statement of a material  fact or omits to state any material fact which

         herein,  in light of the  circumstances  in which  they are  made,  not

                  contaminant,   chemical,  or  industrial  toxic  or  hazardous

                  state  law)  has  occurred  or  is   currently   occurring  in

                  including the  ownership  and operation of the Pipeline,  as a
                  result of which release,  emission, or discharge,  there would
                  be a material  adverse  effect on SWPL,  NOARK or AWP.  To the

                  leased  by  NOARK  and AWP or upon  which  NOARK  or AWP has a

                  returns)  relevant to their future tax liabilities,  including

                  SWPL's knowledge,  is or will be any such examination  noticed
                  or threatened. No material issue or issues have been raised in
                  connection  with any prior or pending  review or audit of said
                  federal,  state,  local or foreign  tax  returns  which may be
                  expected to be raised in the future by such taxing authorities
                  in  connection  with the audit or review of the tax returns of

                  Revenue Code, as amended,  has not been made by NOARK, AWP nor
                  AWP L.L.C.

                           (xvii) NOARK is an Arkansas limited partnership, duly

                  of the  State  of  Arkansas  with  full  power to carry on its
                  business as now being conducted.

                           (xviii)  NOARK is, and has been  since its  creation,
                  treated as a limited  partnership for all purposes under state
                  and federal tax laws, rules and regulations.

                  licenses,  copyrights,  trade  secrets (as defined in 78 Okla.
                  Stat.  ss.  86) or other  assets  of the  same  types as those
                  enumerated  above  which  are  used  in the  operation  of the
                  businesses  of NOARK  or AWP.  NOARK  and AWP are in  material
                  compliance   with  all  such  items  set  forth  in   Schedule
                  12(g)(xix). To the best of their knowledge, after due inquiry,
                  the  conduct  of the  businesses  of  NOARK  and AWP  does not
                  conflict   with,   infringe   upon  or  violate  the  patents,
                  franchises,  trademarks,  service  marks,  processes,  process
                  technology  or copyrights  or other  intangible  assets of any
                  other person or entity.

                           (xx)  To the  best  of  their  knowledge,  after  due
                  inquiry, all material receivables of NOARK, AWP and AWP L.L.C.
                  are fully collectible.

                  nor AWP has nor will AWP L.L.C. or AWP, as applicable,  at the
                  AWP  Contribution  Time  have,  any  material  liabilities  or

         connection  with  (y)  the  Searcy  Gathering  Assets  which  are to be

                  (a) In any case where an indemnified party recovers from third
         parties  all or any part of any  amount  paid to it by an  indemnifying
         party  pursuant  to this  Section  15,  such  indemnified  party  shall
         promptly pay over to the indemnifying party the amount so recovered

                                       33

<PAGE>



         (after deducting  therefrom the full amount of the expenses incurred by
         it in procuring  such recovery and any  additional  amounts owed to the
         indemnified party by the indemnifying party under this Agreement),  but
         not in  excess of any  amount  previously  so paid by the  indemnifying
         party.

                  (b)  The   indemnified   party  shall  be  obligated  to  file
         diligently  and in good faith any claim for Damages with any applicable
         insurer  prior to  collecting  an  indemnification  payment  under this
         Section 15. However,  an indemnified party shall be entitled to collect
         an  indemnification  payment under this Section 15 if such  indemnified
         party has not received  reimbursement from an applicable insurer within
         six months after it has given such insurer written notice of its claim.
         In such event,  the indemnified  party shall assign to the indemnifying
         party any and all rights against its insurers.

                  15.4 Third Person Claim. If a claim by a Person other than the
         Parties is made against one or more of the Enogex  Indemnified  Parties
         or the SWN Indemnified  Parties (the "Indemnified  Party"),  and if the
         Indemnified  Party intends to seek indemnity with respect thereto under
         this Section 15, the Indemnified  Party shall promptly notify the Party
         or Parties having an  indemnification  obligation  with respect to such
         claim (the "Indemnifying  Party") of such claim. The Indemnifying Party
         shall  have  15 days  after  receipt  of  such  notice  to  notify  the
         Indemnified  Party of its agreement to undertake,  conduct and control,
         through  counsel  of its  own  choosing  and at its  own  expense,  the
         settlement  or  defense  thereof,   and  the  Indemnified  Party  shall
         cooperate  with  the  Indemnifying   Party  in  connection   therewith;
         provided,  however,  that (a) the  Indemnifying  Party shall permit the
         Indemnified  Party to participate in such settlement or defense through
         counsel  chosen by the  Indemnified  Party,  provided that the fees and
         expenses of such counsel shall be borne by the Indemnified  Party,  and
         (b)  the  Indemnifying   Party  shall  promptly  assume  and  hold  the
         Indemnified  Party  harmless  from and  against  the full amount of any
         loss,   damage  or  expense  resulting   therefrom.   So  long  as  the
         Indemnifying  Party is  reasonably  contesting  any such  claim in good
         faith, the Indemnified Party shall not pay or settle any such claim, to
         the extent such claim is subject to the  indemnity  provisions  of this
         Section 15. If the  Indemnifying  Party does not notify the Indemnified
         Party  within 15 days  after the  receipt  of the  Indemnified  Party's
         notice of a claim of  indemnity  hereunder  that it elects to undertake
         the defense thereof, the Indemnified Party shall have the right to take
         over the defense of such claim and to contest, settle or compromise the
         claim but  shall not  thereby  waive  any right to  indemnity  therefor
         pursuant to this Agreement,  including without  limitation the right to
         reimbursement  for  all  fees,  costs  and  expenses  incurred  by  the
         Indemnified   Party   (including   attorneys'   fees   and   costs   of
         investigation)   in  such  defense  and  in  contesting,   settling  or
         compromising such claim. The Indemnifying  Party shall not, except with
         the consent of the  Indemnified  Party,  enter into any settlement that
         does not  include as an  unconditional  term  thereof the giving by the
         Person or Persons asserting such claim an unconditional  release to all
         Indemnified  Parties from all  liability  with respect to such claim or
         consent to entry of any judgment.

         Warranties  Contained in Sections 11 and 12. Enogex and EAPC's  maximum
         aggregate liability to SWN and SWPL for breaches of representations and

         18.  Public  Announcements.  The parties agree that prior to making any

this Agreement, the party desiring to make such public announcement or statement
shall consult with the other parties hereto and obtain prior written approval of
the other parties hereto of the text of a public announcement or statement to be
made solely by the party proposing to make such announcement.  Nothing contained
in this Section  shall be  construed to require any party to obtain  approval of
the other parties hereto to disclose information with respect to the transaction
contemplated by this Agreement to any state or federal governmental authority or

regulations   or  orders  of  any   governmental   authority  or  agency  having

Stock Exchange, NASDAQ or any applicable securities laws.

         19.      Dispute Resolution

         19.1 Invoking Procedure.  In the event of a dispute between the Parties
arising  out of or  related  to  this  Agreement  , any  Party  may  invoke  the
procedures  specified  in this  Section  by giving  written  notice to the other
Parties. Such written notice will describe briefly the nature of the dispute and
shall  identify an individual  with authority to settle the dispute on behalf of
that Party.  The Party  receiving  such  notice  shall have ten (10) days within
which to designate  an  individual  with  authority to settle the dispute on its
behalf and to give written notice to the other Parties of its  designation  (the
individuals so designated shall be referred to as the "Authorized Individuals").
In this regard, there shall be only one Authorized  Individual for SWN and SWPL,
and only one  Authorized  Individual  for  Enogex  and  EAPC.  Unless  otherwise
notified, i) the Authorized Individual of SWN and SWPL shall be the President of
SWN, and ii) the Authorized Individual of Enogex and EAPC shall be the President
of Enogex.

         19.2  Investigation.  The  Authorized  Individuals  shall make whatever
investigation each deems appropriate and promptly thereafter,  but no later than
thirty (30) days from the date of the original notice invoking these procedures,
shall commence discussions  concerning resolution of the dispute. If the dispute
has not been  resolved  within  sixty  (60) days  from the date of the  original
notice  invoking  these  procedures,  the  Parties  shall  submit  the matter to
Alternate Dispute Resolution (ADR) in accordance with the following procedure.

         19.3 Neutral.  The Parties shall have ten (10) days from the expiration
of the sixty (60) day period  referred to in Section  19.2,  or the agreement of
the Parties,  to submit the matter to ADR, whichever occurs first,  within which
to agree  upon a  mutually  acceptable  person  not  affiliated  with any  Party
("Neutral").  If no Neutral  has been  selected  within  that time  period,  the
Parties agree jointly to request the American Arbitration Association,  or other
mutually agreed-upon  organization,  to supply within ten (10) days a list of at
least three (3)  potential  Neutrals  with  qualifications  as  specified by the
Parties in the joint request.  Within seven (7) days of receipt of the list, the
Parties shall rank the proposed candidates independently,  exchange rankings and
select as the Neutral the individual who received the highest  combined  ranking
who is available to serve.

         19.4  Schedule.  In  consultation  with the Neutral,  the Parties shall
designate  a  mutually  convenient  time  and  place  for the  ADR,  and  unless
circumstances  require  otherwise,  such time shall be not later than forty-five
(45) days after the selection of the Neutral.

         19.5 Discovery.  In the event any of the Parties have  substantial need
for  information  in the possession of any other Party or a need to take certain
limited depositions and/or production of principal documents in order to prepare
for the ADR, the Parties  shall attempt in good faith to agree on a plan for the
expeditious  exchange of such information.  Should they fail to reach agreement,
any  Party may  request a meeting  with the  Neutral  who shall  assist  them in
reaching an accommodation.

         19.6 Written Submission.  One week prior to the first scheduled session
of the ADR,  each Party shall  deliver to the Neutral and to the other Parties a
written  summary of its views on the matter in dispute.  The summary shall be no
longer than twenty (20) double-spaced pages unless the Parties agree otherwise.

         19.7  Representatives.  In the ADR, each Party shall be  represented by
the  Authorized  Individual  and by counsel.  In addition,  each Party may bring
additional   persons  as  necessary  to  respond  to  questions  or   contribute
information as needed. The number of such additional persons to be allowed shall
be  mutually  agreed by the  Parties  with the  assistance  of the  Neutral,  if
necessary.

         19.8 Structure. The Neutral is authorized to conduct joint and separate
meetings  with the Parties and to help the Parties  structure  whatever  form of
presentation  of the matter in dispute is most likely to facilitate  resolution.
Notwithstanding the form of the presentation, it is the intent of the Parties to
provide an opportunity  for their  Authorized  Individuals,  with or without the
assistance of counsel,  and with the  assistance of the Neutral,  to negotiate a
resolution of the matters in dispute.  In the event the Neutral  holds  separate
private caucuses with a Party, he or she shall keep confidential all information
learned  in  such  private  caucuses  unless  specifically  authorized  to  make
disclosure  of  the  information  to  the  other  Parties.  There  shall  be  no
stenographic, visual, or audio record made of the ADR.

         19.9  Mandatory.  The Parties  agree to  participate  in the ADR to its
conclusion  as  designated  by the  Neutral  and not to  terminate  negotiations
concerning  resolution  of the  matters in dispute  until at least two (2) weeks
thereafter. Each Party agrees not to commence arbitration or seek other remedies
prior to the conclusion of the two-week post-ADR  negotiation  period,  provided
that any Party may commence arbitration on any date after which the commencement
of litigation  could be barred by an  applicable  statute of  limitations  or in
order to request an injunction to prevent  irreparable  harm. In such event, the
Parties agree  (except as prohibited by court order) to continue to  participate
in the ADR to its conclusion.

         19.10 Fees. The fees of, and authorized  costs incurred by, the Neutral
shall be shared equally by the Parties.  The Neutral shall be  disqualified as a
witness,  consultant,  expert,  or  counsel  for any Party  with  respect to the
matters in dispute and any related matters.

         19.11    Later Proceedings.  The ADR is a compromise negotiation for 
purposes of the Federal Rules of Evidence and the Rules of Evidence of the State
of Oklahoma.  The entire procedure is

                                       38

confidential.  All conduct,  statements,  promises, offers, views, and opinions,
whether  oral or written,  made in the course of the ADR by any of the  Parties,
their agents,  employees,  representatives,  or other invitees to the ADR and by
the  Neutral,  who is the  parties'  joint  agent  for  the  purposes  of  these
compromise  negotiations,  are  confidential  and shall,  in addition  and where
appropriate,  be  deemed  to be  work  product  and  privileged.  Such  conduct,
statements,  promises,  offers, views, and opinions shall not be discoverable or
admissible for any purposes,  including impeachment,  in any litigation or other
proceeding  involving  the Parties and shall not be  disclosed  to anyone not an
agent,  employee,  expert,  witness,  or representative  for any of the Parties.
Evidence otherwise  discoverable or admissible is not excluded from discovery or
admission as a result of its use in the ADR.

         19.12    Arbitration.

                  (a) In the event the  Parties  are  unable  to  resolve  their
         dispute in accordance with the foregoing provisions of this Section 19,
         the dispute  shall be submitted to final and binding  arbitration.  The
         arbitration   shall  be  administered   by  the  American   Arbitration
         Association  ("AAA") in accordance  with, and in the following order of
         priority:  (i) the  terms of  these  arbitration  provisions;  (ii) the
         Commercial  Arbitration Rules of the AAA; (iii) the Federal Arbitration
         Act (Title 9 of the United  States  Code);  (iv) the  Oklahoma  Uniform
         Arbitration  Act (15 O.S. ss. 801, et seq.);  and (v) to the extent the
         foregoing are inapplicable,  unenforceable or invalid,  the laws of the
         State of Oklahoma. The validity and enforceability of these arbitration
         provisions  shall be determined  in  accordance  with the same order of
         priority.  In the event of any inconsistency  between these arbitration
         provisions and such rules and statutes,  these  arbitration  provisions
         shall  control.  Judgment upon any award  rendered  hereunder  shall be
         entered  in any court  having  jurisdiction  thereof,  and the  parties
         consent to the  jurisdiction of any state or federal court in Oklahoma.
         Commencement  of and  demand for  arbitration  shall be made by written
         notice  by  the  initiating   party   (claimant)  to  the  other  party
         (respondent)  which  contains a statement of the nature of the dispute,
         the amount involved and the relief or remedy sought ("Notice").

                  (b) The arbitration shall be conducted by a panel of three (3)
         arbitrators (the "Arbitration Panel").  Enogex and EAPC on the one hand
         and SWN and SWPL on the other,  will each nominate one (1)  arbitrator,
         who is  experienced  and  knowledgeable  in the areas  involved  in the
         dispute,  within ten (10) working  days of their  receipt of the Notice
         that arbitration has been demanded and commenced,  and each will notify
         the other party of the name of its selected arbitrator within that same
         time period. If either side refuses to name an arbitrator,  application
         will be made to the Chief Judge of the United States District Court for
         the  Northern  District  of  Oklahoma  requesting  that the Chief Judge
         appoint  an  arbitrator.  If  the  Chief  Judge  declines  to  name  an
         arbitrator,  application  will be made to the AAA. The two  arbitrators
         thus  selected  will confer within ten (10) working days of their final
         selection and agree upon a third arbitrator. If the two arbitrators are
         unable to agree on a third arbitrator within sixty (60) working days of
         their first contact, the nomination of the third arbitrator will follow
         the same procedure as the nomination of a party  arbitrator for a party
         refusing  to make a  selection.  AAA  Rules  regarding  the  selection,
         qualification,  and  challenge  of  arbitrator  shall only apply to the
         second or third arbitrators if those arbitrators

                                       39

<PAGE>



         are  selected  by the AAA.  No member of the  Arbitration  Panel may be
         involved  in the  controversy,  be or have been an  officer,  director,
         representative,  employee  or agent of or for either  party.  The third
         arbitrator shall act as Chairman of the Arbitration Panel.

                  (c) The  costs  and fees of the  arbitrators  selected  by the
         parties shall be borne by the party selecting such  arbitrator,  unless
         otherwise  awarded  by  the  Arbitration  Panel.  The  costs  and  fees
         attributable  to the third  arbitrator  shall be shared  equally by the
         parties, unless otherwise awarded by the Arbitration Panel.

                  (d) The Arbitration Panel may engage engineers, accountants or
         other  consultants that the Arbitration Panel deems necessary to render
         a  decision  in the  Arbitration  Proceeding.  All  fees  of  any  such
         consultants  shall be borne  equally by the parties,  unless  otherwise
         awarded by the Arbitration Panel.

                  (e)  The   arbitration   will  be   governed  by  the  Federal
         Arbitration  Act, 9 U.S.C.  ss.ss.  9 et seq. and the Oklahoma  Uniform
         Arbitration Act, 15 Okla. Stat. ss.ss. 801 et seq. The arbitrators will
         establish a schedule that will result in a final  arbitration  award to
         be  rendered  in  written  form not later than 180 days  following  the
         appointment of the third arbitrator. The place of the arbitration shall
         be Tulsa, Oklahoma.

                  (f) The parties agree that  pre-arbitration  hearing discovery
         is necessary.  Within twenty (20) working days after the appointment of
         the  third  arbitrator,  the  parties  agree to  exchange  lists of the
         witnesses  and  exhibits  each  then  plans  to  call  and  use  in the
         Arbitration Hearing. Within twenty (20) working days after the exchange
         of the witness and exhibit  lists,  the parties may request  additional
         discovery, if any is necessary, from the other party. The parties agree
         to respond to any such additional  request for documents from the other
         party within thirty (30) days after  receiving  such request,  and each
         agrees  to  attempt  in good  faith  to  schedule  the  depositions  of
         witnesses requested by the other side by agreement.  If the parties are
         unable to agree on any aspect of discovery  requested,  such  discovery
         issue shall be presented to and resolved by the Arbitration Panel.

                  (g) Any dispute  relating to or arising under this arbitration
         provision,  including  interpretation  thereof,  shall  be  solely  and
         finally resolved by submission to the Arbitration Panel.

                  (h) A written  decision by two (2) of the arbitrators  will be
         final and binding on the parties.  An arbitration  award entered herein
         can be confirmed by any party in the United States  District Courts for
         the Northern or Western  Districts of Oklahoma or the Western  District
         of Arkansas or any state district courts for the States of Oklahoma and
         Arkansas, and a judgment may be entered on the arbitration award by the
         same court.

                  (i)  Punitive  damages  may not be awarded by the  Arbitration
         Panel. The Arbitration  Panel shall have the power to award recovery to
         the  prevailing  party  of  all or  part  of its  costs,  expenses  and
         attorneys' fees incurred in conjunction with such Arbitration

                                       40

         Proceeding.

                  (j) The parties,  their  Affiliates,  employees,  contractors,
         attorneys  and  auditors  shall keep the  substance  of these final and
         binding arbitration proceedings  confidential to the extent the same is
         permissible,  consistent  with the  responsibilities  of the  attorneys
         under the pertinent Codes of Professional Responsibility or obligations
         which may  reasonably  require  disclosure  to financial  institutions,
         consultants for evaluation purposes or as may be ordered by the federal
         or state  government  or a court of  competent  jurisdiction.  Under no
         circumstances  shall any documents  memorializing  the substance of any
         aspect of these  proceedings  be disclosed or released to the newspaper
         or other media absent the mutual agreement of the parties.  The parties
         will use all  reasonable  efforts to obtain  protective  orders  before
         disclosing  any  terms of these  proceedings  to any  federal  or state
         government or a court of competent jurisdiction.

                  (k) Except for the  internal  costs of each party,  all costs,
         fees and  expenses of any portion of this  dispute  resolution  process
         shall be shared  equally by the  parties,  unless  otherwise  specified
         herein.

         20.  Governing  Law.  The  provisions  of this  Agreement  and,  unless
specifically  otherwise  provided in the document delivered pursuant hereto, the
documents  delivered  pursuant  hereto  shall be governed by and  construed  and
enforced in  accordance  with the laws of the State of Oklahoma,  excluding  any
conflicts-of-law  rule or principle that might refer same to the laws of another
jurisdiction.

         21.  Amendments and Waivers.  No supplement,  modification or waiver of
this Agreement  shall be binding  unless  executed in writing by the Party to be
bound thereby.  The failure of a Party to exercise any right or remedy shall not
be  deemed or  constitute  a waiver of such  right or remedy in the  future.  No
waiver  of any of the  provisions  of this  Agreement  shall be  deemed or shall
constitute  a waiver of any other  provision  hereof,  nor shall any such waiver
constitute a continuing waiver unless otherwise expressly provided.

         22. Binding Effect;  Non-Assignability and Alienation of Benefits. This
Agreement  shall be binding  upon and inure to the  benefit of the  Parties  and
their respective  permitted  successors and assigns;  but neither this Agreement
nor any of the rights,  benefits or obligations  hereunder shall be assigned, by
operation of law or otherwise, by any Party without the prior written consent of
the others. Nothing in this Agreement, express or implied, is intended to confer
upon any Person other than the Parties and their respective permitted successors
and assigns, any rights, benefits or obligations hereunder.

         23.  Severability.  If one or more of the provisions  contained in this
Agreement or in any other  document  delivered  pursuant  hereto shall,  for any
reason,  be held to be invalid,  illegal or unenforceable  in any respect,  such
invalidity, illegality or unenforceability shall not affect any other provisions
of this Agreement or any other such document.

income tax purposes at the beginning of such year or other period,  Depreciation
shall be an amount  which  bears the same ratio to such  beginning  Gross  Asset
Value as the  Federal  income  tax  depreciation,  amortization,  or other  cost
recovery  deduction  for such  year or  other  period  bears  to such  beginning

         3.1 Management Committee.  The Partnership (including all NOARK Related
Entities)  shall be  managed  by the  Management  Committee,  which,  except  as
otherwise  provided  in this  Agreement  (including  without  limitation,  those

Interest of Partners) shall have exclusive authority with respect to all affairs
of the Partnership (including any NOARK Related Entities).

         3.2 Composition of Management Committee. The Management Committee shall

with new designees at any time upon giving written notice to the other Partners.

necessary and requests in writing,  and at such times as requested in writing by

                                       10

<PAGE>



all members of the Management  Committee,  notice of all meetings shall be given
by the Project Leader to all Management Committee members and to all Partners at
least five (5) days in advance of the time set for the meeting.  The notice will
be accompanied by an agenda of the matters the proponent of the meeting  intends
to  present  at the  meeting;  provided,  that,  the  scope of the  issues to be
discussed at the Management Committee meeting need not be limited to the matters
stated in the notice.  Any member of the  Management  Committee may require that
items be added to the agenda by notice to all other Management Committee members
and Partners given at least  forty-eight (48) hours prior to the meeting.  Items
may be added to the agenda at a Management Committee meeting only if all members

only agenda items may be formally decided at any Management  Committee  meeting.
All meetings of the Management  Committee shall be held in person or by means of

Committee may take action in lieu of a meeting  through a written consent signed
by all of the members of the Management  Committee.  The presence in person,  by
proxy or through  alternates of not less than fifty percent (50%) of the members
of the  Management  Committee  shall be necessary to  constitute a quorum at any
meeting for the transaction of business.  Unless otherwise  provided herein, the
affirmative  vote of a majority of the members in attendance at a meeting of the
Management  Committee  at  which a  quorum  is  present  ("Management  Committee
Approval") shall be necessary and sufficient to take any action on behalf of the
Management  Committee.  Each member on the Management  Committee  shall have one
vote.  In the  absence of a quorum,  a majority  of the  members  present at the
meeting may adjourn  such  meeting  from time to time until a quorum is present.
Written  minutes of all  Management  Committee  meetings shall be maintained and
distributed promptly to all members of the Management Committee.

                  (a) Immediately upon execution of this Agreement, each Partner
         shall  designate,  by notice  given to each  other  Partner  and to the
         Partnership,  an individual to serve as its primary  representative  to
         vote at meetings of the  Partners.  By like  notice,  each  Partner may
         designate not more than one alternative  representative  who shall have
         authority to act in lieu of its primary representative.  In the absence
         of a primary representative,  the designated alternate may serve in the
         place of the primary  representative.  Any Partner may at any time,  by
         written notice to all other Partners and to the Partnership, remove its
         primary representative or alternate  representative and designate a new
         primary representative or alternate representative.

                  (b) The Project  Leader  shall  preside at all meetings of the
         Partners.  Meetings  of the  Partners  may be called at such  times and
         places, and in such manner, as requested in writing by a representative
         of any  Partner.  Such  request  shall  identify  the items the Partner
         proposes to be placed on the agenda for such meeting.  Unless notice is
         waived by the  representatives of all Partners,  notice of all meetings
         shall be given by the Project Leader to

                                       11

         all representatives and alternates at least five days in advance of the
         time set for the meeting.  The notice will be  accompanied by an agenda
         of matters to be presented by the Project  Leader.  Any  representative
         may  require  that  items be  added  to the  agenda  by  notice  to the
         representatives  of all other Partners given at least two days prior to
         the date of the meeting.  Although discussion of other matters may take
         place,  only agenda items may be formally  decided;  provided,  that by
         unanimous vote of the  representatives at a meeting in which at least a
         SuperMajority in Interest of the Partners are represented, items may be
         added to the  agenda.  All  meetings of the  Partners  shall be held in
         person or by means of  conference  telephone or similar  communications
         equipment  by means of which all persons  participating  in the meeting
         can hear each other. All expenses of the meeting and notification shall
         be borne by the  Partnership.  Representatives  of  Partners  (or their
         respective   designated   alternates)  holding  at  least  80%  of  the
         Partnership  Percentages  shall be necessary to  constitute a quorum at
         any  meeting  for the  transaction  of  business.  In the  absence of a
         quorum,  a majority of the  representatives  present at the meeting may
         adjourn  such  meeting  from time to time  until a quorum  is  present.
         Written  minutes of all meetings  shall be maintained  and  distributed
         promptly to all representatives.

                  (c) Each  representative at a meeting of Partners shall have a
         vote equal to the Partnership Percentages of the Partner he represents.

                  (d) Personal presence of Partners'  representatives  shall not
         be required,  provided  that at or prior to the meeting time either (i)
         an effective written consent to or rejection of such proposed action is
         submitted  to the Project  Leader or (ii) a proxy is  submitted  to the
         Project Leader.  Attendance by the  representatives  of the Partner (or
         its  respective  designated  alternate)  and  voting  in  person at any
         meeting shall revoke any written consents or rejections of such Partner
         or any proxies previously submitted with respect to the action proposed
         to be taken at such meeting.

                  (e) Any matter on which the  Partners are  authorized  to take
         action  under this  Agreement or under law may be taken by the Partners
         without a meeting and shall be as valid and  effective  as action taken
         by the  Partners at a meeting  assembled,  if written  consents to such
         action by the Partners are signed by the Partners entitled to vote upon
         such action at a meeting who hold the Partnership  Percentages required
         to authorize such action, and are delivered to the Project Leader.

by the Budget,  and, in the case of Persons  employed by or affiliated  with any
Partner  or an  Affiliate  of any  Partner,  the  provisions  of the  Accounting
Procedures  attached  hereto as  Exhibit  B; (iv)  preparing  or  causing  to be
prepared reports,  statements and other relevant information for distribution to
the Partners;  (v) opening  accounts and deposits and  maintaining  funds in the
name of the  Partnership  (including any NOARK Related Entity) in banks or other
financial  institutions or investing such funds; and (vi) making all reports and
filings required by governmental authorities.

         (d) The Project  Leader shall  initially be E. Keith Mitchell who shall
serve in such capacity  until the earlier of his death,  resignation or removal.
In order for the  Project  Leader to  receive  the  benefits  he has  heretofore
received,  the Project  Leader shall be employed by EAPC, but shall be dedicated
full time to the  Partnership.  The Project  Leader shall maintain his office at
the principal business office of the Partnership.

         (e) The  Project  Leader  shall be subject  to removal  with or without
cause at any  time by EAPC  (or any  Substituted  Partner  succeeding  to all of
EAPC's  Partnership  Interest);  provided such removal shall not be arbitrary or
capricious. If a vacancy occurs in the office of Project Leader, whether through
death,  resignation,  removal or otherwise, the Partners shall consult regarding
the appointment of a new Project Leader.  After such consultation,  EAPC (or any
Subsequent Partner succeeding to all of EAPC's Partnership  Interest) shall have
the  authority  to propose the new Project  Leader who shall  become the Project
Leader  upon the consent of SWPL (or any  Subsequent  Partner(s)  succeeding  to
SWPL's Partnership Interest),  which consent shall not be unreasonably withheld.
It  shall  be  deemed  unreasonable  for  SWPL  (or  any  Subsequent  Partner(s)
succeeding to SWPL's Partnership  Interest) to withhold its consent by reason of
the fact that the proposed  Project Leader is or was an employee of EAPC (or any
Subsequent Partner  succeeding to all of EAPC's  Partnership  Interest) or of an
Affiliate of EAPC.

         (f) The Project  Leader shall have power to contract with third parties
on behalf of and in the name of the  Partnership  (including  any NOARK  Related
Entity) when the contract is approved by the Management  Committee (or is within
the approval levels delegated to him by the Management  Committee),  and to make
expenditures on behalf of the  Partnership  (including any NOARK Related Entity)
when such expenditures have been approved by the Management  Committee (subject,
where applicable, to the provisions of Section 3.5) or when such expenditures do
not exceed that  permitted  under the  approved  annual  Budget by more than ten
percent (10%) for

                                       16

<PAGE>



the line item or items in  question  (based on a Budget  format  similar to that
historically  used  by the  Partnership)  or  $50,000.  Upon  execution  of this
Agreement,  the Project  Leader  shall have  authority to make  expenditures  in
fiscal year 1998 in accordance  with the existing  Budget of the Partnership for
fiscal year 1997 until a new Budget is approved.

         (g) The Project  Leader  shall  submit to the  Partners for approval an
annual  Budget  setting  forth on a monthly  basis the  anticipated  costs to be
incurred  in  connection  with the  Partnership  (including  the  NOARK  Related
Entities),  including  without  limitation  the  cost  of  operating  and  field
personnel  providing  day-to-day  operations of the System,  and the anticipated
capital  costs to be incurred in  connection  with the System  based on a Budget
format similar to that historically  used by the Partnership.  A proposed Budget
shall be provided to the Partners as soon as practicable  following execution of
this  Agreement for the period  covering  calendar year 1998 and by December 1st
for each year thereafter  during the term of this Agreement.  Such Budgets shall
be subject to the approval  requirements  of Section  3.5. In the event  Partner
approval  of any  Budget as  required  by  Section  3.5 is not  obtained  by the
commencement  of the year to  which  such  Budget  applies,  the  most  recently
approved Budget shall be utilized until such new Budget is approved.

         (h) The  Project  Leader may rely and shall be  protected  in acting or
refraining from acting upon any resolution,  certificate, statement, instrument,
opinion,  report, notice,  request,  consent,  order, bond, debenture,  or other
paper or  document  believed  by it to be  genuine  and to have  been  signed or
presented  by the proper party or parties.  The Project  Leader may consult with
legal  counsel,  accountants,  appraisers,  management  consultants,  investment
bankers and other  consultants and advisers  selected by it and any act taken or
omitted in reliance upon an opinion  including,  without  limitation,  a written
opinion of counsel (who shall be regular or special counsel to the  Partnership)
acceptable to the Project  Leader of such persons as to matters that the Project
Leader  reasonably  believes to be within such person's  professional  or expert
competence  shall be conclusively  presumed to have been done or omitted in good
faith and in accordance with such opinion.

         (i) The Project  Leader shall have the right,  in respect of any of his
powers or duties hereunder,  to delegate same to any employee of the Partnership
or, to any Partner.  Each such Person shall have full power and  authority to do
and perform each and every act and duty that is so delegated to such Person.

         (j) In the event the Project  Leader incurs  expenditures  in emergency
situations  to  safeguard  life  or  property  or to  maintain  the  operational
integrity of the System at design capacity,  the Project Leader shall notify the
Management  Committee  and the  Partners of the  emergency  situation as soon as
reasonably possible after any such emergency  situation.  Such costs so incurred
by the Project  Leader  shall not require the prior  approval of the  Management
Committee  or  the  Partners;   provided,  however,  that  any  expenditures  or
transactions  undertaken  shall involve terms that are standard and customary in
the industry  and do not expose or subject the  Partnership  to any  inordinate,
unusual or unreasonable  risks,  liabilities or obligations  given the facts and
circumstances  which exist at the time of the Project  Leader  committing to any
such expenditures or transactions.

                                       17

<PAGE>



The  Partners  acknowledge  that the facts  and  circumstances  of an  emergency
situation may require terms,  expenditures  or  transactions  which under normal
situations would be different.

         3.7      Delegation

         (a) The Management  Committee  shall have the authority to delegate any
of its duties and authority to any Partner,  the Project Leader,  or, subject to
Section 3.5, a committee.  Any such delegation  shall be in writing and shall be
revocable at any time by the Management Committee.

         (b) The Partners shall make available to the Partnership (including any
NOARK Related Entity) executive, administrative and operating personnel with the
appropriate   backgrounds  and  experience  to  provide  such  services  as  the
Management  Committee  may  reasonably  delegate for them to provide and to make
available  to the  Management  Committee  sufficient  time of  such  executives,
administrative   and   operating   personnel   to   promptly,   faithfully   and
professionally  provide such  services.  A Partner may utilize the personnel and
resources of not only itself,  but also of its  Affiliates  and other Persons in
the performance of such services.

         (c) The Partners  shall be reimbursed by the  Partnership in accordance
with the Accounting  Procedures attached hereto as Exhibit B, for all direct and
indirect  costs and  expenses  incurred in providing  services  delegated by the
Management Committee to be provided by them.

         (d) Subject to the  provisions  of this  Section  3.7,  the  Management
Committee shall be deemed to have delegated i) to SWPL the continued performance
of the  accounting  services for the  Partnership  and the  performance of field
operations and field operations support services SWPL has historically  provided
to the  Partnership in Arkansas as well as the  performance of field  operations
and field  operations  support  services in those areas where the  facilities of
NOARK and Ozark are in close  proximity for which the Partners agree SWPL should
provide  such  services  and ii) to  EAPC  the  performance  of  operations  and
operations support services to provide support,  direction and assistance to the
Project Leader in the operation of the Partnership  (including the NOARK Related
Entities) and the System.

         (e) Subject to Section 3.5, the Management  Committee may designate one
or more committees (including,  specifically,  an executive committee),  each of
which shall be comprised of one or more of its members, and may designate one or
more of its members as alternate  members of any committee,  who may, subject to
any  limitations  imposed  by  the  Management  Committee,   replace  absent  or
disqualified  members at any meeting of that committee.  Any such committee,  to
the  extent  provided  in such  resolution,  shall  have  and may  exercise  the
authority  delegated to it by the Management  Committee in the management of the
business and affairs of the Partnership, subject to the limitations set forth in
the Act and this Agreement.





                                       18

         3.8      Officers.

         (a) Except for the chief  executive  officer,  who shall be the Project
Leader,  the  Management  Committee  may appoint such  officers and agents as it
deems necessary or appropriate,  who shall be appointed for such terms and shall
exercise such powers and perform such duties as shall be determined from time to
time by the  Management  Committee.  Any two or more  offices may be held by the
same person.

         (b) Any officer, agent or member of a committee elected or appointed by
the Management  Committee may be removed by the Management Committee at any time
with or without cause.

         3.9 Claims.  The Project Leader shall be responsible for overseeing the
settlement or litigation and defending of any and all claims, damages, or causes
of  action  in  favor of any one  other  than the  Partners  arising  out of the
Operation of the System (as defined in the Accounting  Procedures) which are not
covered  by  insurance;  provided,  that  Project  Leader  shall  report  to the
Management  Committee from time to time with respect to such claims,  damages or
causes of action  and the  disposition  thereof.  The  decision  to settle or to
litigate  and defend  against any such  claim,  demand or cause of action may be
made by Project Leader in accordance  with its best judgment and discretion when
the amount involved is $50,000 or less, provided, however, that if the aggregate
of the amounts  payable by the Partnership in connection with any final judgment
against the Partnership and/or the settlement of any claim or claims against the
Partnership during any fiscal year exceeds $250,000,  any subsequent settlements
shall  be  effected  during  such  fiscal  year  only  with  the  approval  of a
SuperMajority in Interest of the Partners.  Decisions to settle or to defend and
litigate  (i) any single  claim which  involves any amount in excess of $50,000,
(ii) any claim which is commenced against the Partnership during any fiscal year
when the aggregate of all claims  commenced  against the Partnership  during the
same  fiscal year have  involved  amounts in excess of  $250,000,  and (iii) any
claim in which the Project  Leader is named as a defendant or  respondent or has
an interest in the claim or the proceedings which is adverse to the Partnership,
shall be made only with the  approval  of a  SuperMajority  in  Interest  of the
Partners.

         3.10  Disputed  Charges.  Within the time  provided  in the  Accounting
Procedures and  regardless of whether the  applicable  Budget has been exceeded,
the Management Committee or any Partner may take written exception to all or any
portion of any bill or statement rendered by a Partner to the Partnership on the
ground that the same was not a  reasonable  expense or  expenditure  incurred in
good  faith in  connection  with the  Operation  of the  System (as such term is
defined in the Accounting Procedures). NOARK shall nevertheless pay in full when
due the amount of all  statements  submitted  by a Partner.  Thereafter,  at its
discretion on the vote of Partners  representing at least 70% of the Partnership
Interests  remaining  after excluding the Partner's  Partnership  Interest whose
bill or statement is in dispute, the Management Committee may submit the dispute
to the dispute  resolution  procedures  set forth in Article XIII,  and, in such
event the Partners  agree to utilize such  procedures in resolving such dispute.
If the amount as to which such written exception is taken or any part thereof is
ultimately determined in arbitration not to be a reasonable expense or

                                       19

<PAGE>



expenditure  incurred  in good faith in  connection  with the  Operation  of the
System, such amount or portion thereof (as the case may be) shall be refunded to
NOARK together with interest  thereon at one hundred basis points over the prime
rate from time to time charged by Citibank,  N.A., New York, N.Y. to responsible
commercial and industrial  borrowers,  not in excess of the maximum lawful rate,
for the period from the date of payment by NOARK to the date of refund.



                                   ARTICLE IV
                          FINANCING OF THE PARTNERSHIP

         4.1 Existing Capital Accounts Balances.  Schedule 4.1 hereto sets forth
the Capital Accounts of the Partners as of the date of this Agreement which have
been agreed to by the Partners.

         4.2      Capital Contributions.

         (a) In  order  to meet  the  funding  requirements  of the  Partnership
(including  any NOARK  Related  Entity),  the  Management  Committee  shall have
authority to make mandatory capital calls on the Partners for cash contributions
in amounts that the Management  Committee  deems  necessary or advisable to fund
capital and operational  needs of the  Partnership  (including any NOARK Related
Entity).  With respect to each mandatory capital call, each Partner shall within
thirty (30) days of receiving such written notice  contribute to the Partnership
in cash that portion of the total call equal to its Partnership Percentage.

         (b)   Notwithstanding   the  language  of  Section  4.2(a)  above,  the
Management  Committee shall not have authority to issue mandatory  capital calls
to fund a proposed  Expansion  of the  System,  other than  Expansions  included
within an approved Budget. Any such Expansion shall be subject to the consent of
a SuperMajority in Interest of the Partners;  provided, that, if such consent is
not  obtained  within  thirty (30) days of the  submittal  to the  Partners of a
proposal for such an Expansion  (which consent of any Partner may be conditioned
upon approval of such Partner's board of directors to be obtained (i.e. approved
or  rejected)  within  sixty (60) days of the  submittal  to the Partners of the
proposed  Expansion),  but one of the Partners (the "Proposing Partner") desires
to pursue such Expansion,  the Proposing Partner shall contribute to the capital
of the  Partnership  all of the funds  necessary to finance such Expansion (such
contribution  a  "Special  Capital   Contribution")  and  shall  following  such
contribution  receive,  in addition to any other  distributions  provided for in
this Agreement,  an additional cash distribution  equal to all of the additional
net operating income  attributable to the Expansion (which shall not include any
revenues  realized  from the  replacement  of volumes being  transported  on the
System  prior to the  Expansion)  until the  Proposing  Partner has  received an
amount equal to 200% of the Special Capital  Contribution  made by the Proposing
Partner.

         (c) The Partners agree that the Existing  Loans,  including  applicable
interest,  shall be repaid as follows:  (i) sixty  percent (60%) of the Existing
Loans, including applicable interest, shall

                                       20
<PAGE>



be repaid out of any amounts otherwise distributable to SWPL, before taking into
account debt service on the Existing Loans,  under this Agreement and (ii) forty
percent (40%) of the Existing Loans,  including  applicable  interest,  shall be
repaid out of any amounts  otherwise  distributable to EAPC,  before taking into
account  debt  service on the  Existing  Loans,  under this  Agreement.  If such
amounts are insufficient to pay a Partner's percentage share (i.e. 60% or 40% as
set forth above) of the debt service on the Existing Loans, including applicable
interest, in accordance with their terms, then such Partner shall be responsible
to contribute to the capital of the  Partnership  amounts  sufficient to pay its
percentage share (i.e. 60% or 40% as set forth above) of the debt service on the
Existing Loans,  including applicable interest, and shall do so upon notice from
the Project Leader.  Such Capital  Contributions by the Partners shall not alter
the Partnership Percentages of the Partners.  Default by a Partner in the making
of such Capital  Contributions  shall cause it to be deemed a Delinquent Partner
subject to the provisions of Section 4.3 hereof.

         (d) Notwithstanding anything to the contrary in Section 4.2(c) above or
elsewhere in this  Agreement,  it is understood and agreed that the terms of any
Existing  Loans  may in the  future  (but do not  currently)  provide  that  the
amortization  of the principal  amount  thereof shall be borne or allocated in a
manner different from the percentages set forth in Section 4.2(c) or any Partner
may direct the Project  Leader to apply amounts of  Partnership  cash  otherwise
distributable  to such  Partner  (except  amounts  to be paid to other  Partners
pursuant  to the  other  provisions  of  this  Agreement)  to the  repayment  or
prepayment  of the  principal  amount  of the  Existing  Loans in  excess of the
amounts  required to be repaid under the terms of the Existing  Loans,  provided
such Partner bears all costs and penalties of doing so. Consequently,  a Partner
may thereby pay or bear more than its attributable  percentage (i.e. 60% or 40%)
of the principal  amount of the Existing Loans to be repaid.  In such event, the
percentages  of the then  outstanding  principal  amount of the  Existing  Loans
payable out of the distributable  amounts attributable to the Partners set forth
in Section  4.2(c)  shall be adjusted as  appropriate  to reflect the  resulting
percentage of the aggregate  outstanding  principal amount of the Existing Loans
then attributable to each Partner.

         4.3  Failure  to  Contribute.  If any  Partner  fails to make a Capital
Contribution as required under Section 4.2(a) or (c) above, the Partnership may,
in addition to the other rights and remedies the  Partnership may have under the
Act or applicable law, take such enforcement action (including, the commencement
and  prosecution  of court  proceedings)  against such Partner as the Management
Committee  considers  appropriate  and  such  Partner  shall  be  deemed  to  be
delinquent ("Delinquent  Partner").  Moreover, each remaining Partner who is not
delinquent  shall have the right,  but not the  obligation,  to contribute  that
portion  of the  amount  defaulted  by the  Delinquent  Partner  equal  to  such
remaining  Partner's  Partnership  Percentage  expressed as a percentage  of the
Partnership  Percentage of all such  remaining  Partners who elect to contribute
their  applicable  portion of the  defaulted  Capital  Contribution.  In such an
event,  the  Partner(s)  who  contributes  on behalf of the  Delinquent  Partner
("Contributing  Partner") will be entitled to a priority distribution out of the
first  cash  distributions   which  would  otherwise  be  distributable  to  the
Delinquent Partner equal to three hundred percent (300%) of the amount which the
Contributing Partner contributed on behalf of the Delinquent Partner.  Following
satisfaction of this priority distribution, and any other priority distributions
provided for in this Agreement,  distributions  would be made in accordance with
Section

                                       21

<PAGE>



5.7 hereof.  The amount  contributed on behalf of a Delinquent  Partner shall be
secured by such Delinquent  Partner's interest in the Partnership.  Each Partner
who may  hereafter  be deemed  delinquent  hereby  grants  to each  Contributing
Partner, a security interest in such Delinquent Partner's Partnership Interest.

         4.4 Capital  Accounts.  A separate Capital Account shall be established
and maintained by the  Partnership  for each Partner in the manner  described in
the definition of the term "Capital Account" in Article I hereof.

         4.5 Loans by  Partners.  No Partner  shall be required to make loans to
the Partnership. Loans may be made, however, with the approval of the Management
Committee,  by any  Partner  to the  Partnership  and such  loans  shall  not be
considered contributions to the capital of the Partnership.  To the extent loans
are made by any Partner to the  Partnership,  they shall be made on terms, as to
interest rates and other finance charges,  as are comparable to amounts that are
charged by unrelated banks and other financial  institutions on comparable loans
for the same purpose.

         4.6 Interest.  No interest  shall be paid to any Partner on the initial
or any subsequent Capital Contribution to the Partnership.

         4.7 Time for Return of  Contributions.  No Partner shall be entitled to
compel  the  return  of its  Capital  Contribution.  Upon the full and  complete
winding up and liquidation of the business and affairs of the  Partnership,  the
Partners shall be entitled to distributions as set forth in Article X.

         4.8 Limited Liability of the Limited Partners. Notwithstanding anything
to the contrary  contained herein, the liability of a Limited Partner for any of
the debts,  losses or  obligations  of the  Partnership  shall be limited to the
Limited  Partner's  Capital  Contributions.  No Limited  Partner  shall have any
personal  liability  whatsoever,  whether to the Partnership or any third party,
for the debts of the Partnership or any of its losses.

         4.9 Benefits of  Agreement.  Nothing in this  Agreement,  and,  without
limiting the  generality  of the  foregoing,  in this  Article IV,  expressed or
implied,  is  intended  or shall be  construed  to give to any  creditor  of the
Partnership  or any creditor of any Partner or of any other  Person,  other than
the Partners and the Partnership,  any legal or equitable right, remedy or claim
under or in respect to this  Agreement or any covenant,  condition or provisions
herein  contained,  and such provisions are and shall be held to be for the sole
and exclusive benefit of the Partners and the Partnership.


                                    ARTICLE V
                CAPITAL AND INCOME ALLOCATIONS AND DISTRIBUTIONS

         5.1 Allocations  Controlling for Capital Account Purpose.  The Partners
agree that all items of Partnership income, gain, loss and deduction realized by
the Partnership from its operation or upon the sale or other  disposition of its
assets shall be credited or charged to the Capital Accounts

                                       22

<PAGE>



of the  Partners  and  further,  to the  extent  allowed  by the law,  among the
Partners for Federal income tax purposes in accordance with Sections 5.2 through
5.6. The allocation of Partnership income, gain, loss and deduction to a Partner
whose  interest in the  Partnership  terminates or to a newly  admitted  Partner
shall be based upon an actual  closing of the books of the  Partnership  for the
period ending on the date of such  termination or admission  except as otherwise
determined by the  Management  Committee.  In addition,  upon the closing of the
Ozark  Acquisition,  there  shall  be an  actual  closing  of the  books  of the
Partnership  for the  period  ending  on the date of the  closing  of the  Ozark
Acquisition,  when the Partnership  Percentages  will change as specified in the
definition of  Partnership  Percentage.  Further,  upon the Inservice  Expansion
Date,  there shall be an actual closing of the books of the  Partnership for the
period ending on the date of the Inservice  Expansion Date, when the Partnership
Percentages   will  change  as  specified  in  the   definition  of  Partnership
Percentages. For purposes of making the allocations under this Agreement for the
periods ending on the Ozark  Acquisition  and the Inservice  Expansion Date, the
allocation of Partnership income, gain, loss and deduction to a Partner shall be
based upon such dates.

         5.2 General  Allocation  of Profits and Losses.  After giving effect to
the  special  allocations  set forth in Sections  5.3  through  5.6 hereof,  the
Profits and Losses for any fiscal year, or portion thereof, as applicable, shall
be allocated to the Partners in accordance with the  Partnership  Percentages of
the respective Partners.

         5.3  Special  Interest  Expense.   The  Partnership   interest  expense
deductions  incurred with regard to the Existing  Loans as referenced in Section
4.2(c) shall be allocated to Partners as follows:

                                    SWPL                      60%
                                    EAPC                      40%

In the  event  the  percentages  of the  outstanding  principal  amounts  of the
Existing Loans payable out of the  distributable  amounts  attributable  to each
Partner are adjusted pursuant to Section 4.2(d), the foregoing percentages shall
be subject to  adjustment  to reflect the same  percentages  as the  percentages
established pursuant to Section 4.2(d).

         5.4      Preferential Allocations.

         (a) During each fiscal year of the period  commencing  on the Inservice
Expansion Date and ending on December 31, 2009 (the "Special Allocation Period")
SWPL shall receive a special  allocation of Partnership gross revenues (items of
gross  income and gain) in  accordance  with the  formula set forth  below.  For
purposes of this Section  5.4(a),  a fiscal year shall be a calendar year except
that the first fiscal year of the above  described  period shall commence on the
Inservice  Expansion  Date and end on December 31 of the calendar  year in which
the Inservice Expansion Date occurs.

           Special Revenue Allocation      =     Base Amount - Increased Volume
                                 Amount, where:

                                       23

<PAGE>



                  (1)      Base Amount = for each fiscal year during the Special
                           Allocation  Period,  the amount specified on Schedule
                           5.4(a) for such fiscal year

                  (2)      Increased Volume Amount =

                           (a)      the product of (i)the average daily quantity
                                    of gas(in MMBtu's)moved on the System during
                                    the fiscal year less the Firm Quantities (as
                                    defined  below)  for such year (but not less
                                    than  244,000  MMBtu's per day less the Firm
                                    Quantities),  multiplied  by (ii) 25% of the
                                    average  margin (per MMBtu)  realized by (x)

                                    not be less than $.16 per MMBtu), multiplied
                                    by (iii) the  number of days in such  fiscal

                  (3)      For  purposes  of  the   foregoing,   Firm   Business
                           Agreements  shall  mean  firm gas  transportation  or
                           sales  agreements  having a  primary  term of one (1)
                           year or more  between any member of the  Preferential
                           Allocation  Group and customers (such customers being
                           other  than   Affiliates   which  are  NOARK  Related
                           Entities).

                  (4)      For  purposes  of  this  Section  5.4,  the  "average
                           margin" realized by the Preferential Allocation Group
                           shall  mean  (i) in the  case  of  transportation  or
                           gathering   revenues,   the  average  gross  revenues
                           received  (per MMBtu) from  shippers for the movement
                           of gas on the System  (including  any demand  charges
                           received under firm  transportation  agreements which
                           are not Firm  Business  Agreements),  and (ii) in the
                           case of sales  revenues,  the average gross  revenues
                           received  (per  MMBtu)  from  the  sale of gas  after
                           subtracting  therefrom  the average costs (per MMBtu)
                           directly  incurred in making  such  sales,  including
                           without   limitation  gas  costs,   gathering  costs,
                           transportation   costs  and  any  related   imbalance
                           penalties.  In addition,  for purposes of calculating
                           the  Special  Revenue  Allocation,  in the  event the
                           Preferential  Allocation  Group  engages in  multiple
                           transactions    involving    the   same   gas,   such
                           transactions shall be considered a single transaction
                           in determining  the "average daily  quantities"  from
                           such  transaction and the "average  margin"  realized
                           from such transaction.

         (c) The  Special  Revenue  Allocation  for any  fiscal  year  shall  be
determined  within sixty (60) days following the end of the fiscal year to which
such Special  Revenue  Allocation is applicable,  but shall be effective for the
fiscal year in which the revenues  were  received.  In no event will the Special
Revenue Allocation be less than zero.

         (d) Schedule 5.4(d) attached hereto, sets forth several examples of the
calculation of the Special Revenue Allocation.

         5.5      Special Profits Allocations.

         (a) After making the special  allocation of Partnership  gross revenues
(items of gross income and gain)  pursuant to Section 5.4 hereof and the special
allocation  of  Partnership  deductions  pursuant  to Section  5.3  hereof,  the
Partnership  Profits  shall be specially  allocated  to the Partners  which have
received  additional cash distributions in the current or prior years related to
contributions  by  Contributing  Partners  pursuant  to Section 4.3 above in the
following  manner and amount:  Partnership  Profits  otherwise  allocable to the
Delinquent  Partner  (i.e.  Profits  which  would  have  been  allocated  to the
Delinquent  Partner if this Section  5.5(a) did not exist) shall be allocated to
the  Contributing  Partners until the cumulative  amount of Partnership  Profits
allocated  pursuant to this Section 5.5(a) equals the  cumulative  amount of the
cash distributions  otherwise distributable to the Delinquent Partner, but which
are made to the Contributing Partners as provided in Section 4.3.

         (b) After making the special  allocation of Partnership  gross revenues
(items of gross  income and gain)  pursuant to Section  5.4 hereof,  the special
allocation  of  Partnership  deductions  pursuant  to Section 5.3 hereof and the
special allocation of Partnership Profits pursuant to Section 5.5(a) hereof, the
Partnership  Profits  shall be specially  allocated  to the Partners  which have
received  additional cash distributions in the current or prior years related to
an Expansion  pursuant to Section  4.2(b) above until the  cumulative  amount of
Partnership  Profits  allocated  pursuant  to this  Section  5.5(b)  equals  the
cumulative  amount  of  such  additional  cash  distributions  received  by  the
respective Partners.

         5.6      Other Allocation Rules.

         (a)  Section  754  Adjustments.  To the  extent  an  adjustment  to the
adjusted tax basis of any Partnership  asset pursuant to Code ss. 734(b) or Code
ss. 743(b) is required, pursuant to Treas. Reg. ss. 1.704-1(b)(2)(iv)(m),  to be
taken  into  account  in  determining  Capital  Accounts,  the  amount  of  such
adjustment  shall  increase  the basis of the  asset or loss (if the  adjustment
decreases such basis) and such gain or loss shall be specially  allocated to the
Partners in a manner  consistent with the manner in which their Capital Accounts
are required to be adjusted pursuant to such section.

         (b) Code Section 704(c) Tax  Allocations.  In accordance  with Code ss.
704(c) and the  Regulations  thereunder,  income,  gain, loss and deduction with
respect to any property  contributed  to the capital of the  Partnership  shall,
solely for tax  purposes,  be allocated  among the General  Partners and Limited
Partners so as to take account of any  variation  between the adjusted  basis of
such property to the  Partnership for Federal tax purposes and its initial Gross
Asset Value using the  "traditional  method with  curative  allocations"  as set
forth in Treas. Reg. ss.  1.704-3(c).  In the event the Gross Asset Value of any
Partnership  asset is adjusted as required  by the  definition  of "Gross  Asset
Value" as contained in this Agreement,  subsequent  allocations of income, gain,
loss and  deduction  with  respect  to such  asset  shall  take  account  of any
variation  between  the  adjusted  basis of such  asset for  Federal  income tax
purposes  and its Gross Asset Value in the same manner as under Code ss.  704(c)
and the Regulations  thereunder.  Any elections or other  decisions  relating to
such  allocations  shall be made by the  General  Partners  in any  manner  that
reasonably  reflects the purpose and  intention of this  Agreement.  Allocations
pursuant to this Section 5.6(b) are solely for purposes of federal,  state,  and
local income taxes and shall not affect,  or in any way be taken into account in
computing,  any Partner's  Capital  Account or share of Profits,  Losses,  other
items, or distributions pursuant to any provision of this Agreement.

         5.7 Cash Distributions. Except as otherwise provided in this Agreement,
the  Management  Committee in its sole  discretion  shall have the  authority to
cause the  Partnership to allocate and distribute  cash or other property to the
Partners monthly on a basis in accordance with this Agreement. All distributions
shall be made in accordance with the  Partnership  Percentages of the respective
Partners,  net of each  Partner's  required  share of payments  on the  Existing
Loans,  including interest thereon, as provided in Section 4.2(c), except for i)
distributions  related to the funding of Expansions  under Section  4.2(b),  ii)
distributions  under Section 4.3 and iii) distributions in liquidation  pursuant
to Article X. It shall be a policy of the Partnership to distribute the maximum

                                       26

<PAGE>



amount of cash available after taking into account anticipated future sources of
cash and the  working  capital  and cash  requirements  to meet the  current and
anticipated future obligations of the Partnership.

         5.8 Amounts Withheld.  All amounts withheld pursuant to the Code or any
provision  of any  state  or  local  tax law  with  respect  to any  payment  or
distribution  to the Partnership or the Partners shall be treated as distributed
to the Partners  pursuant to Section 5.7 for all purposes under this  Agreement.
The  Management  Committee  shall  allocate such amounts among the Partners in a
manner that is consistent with Article V hereof and applicable law.

         5.9  Reimbursements.  The  Project  Leader and any  Partner  performing
services  or  providing  goods  to  the  partnership,  in  accordance  with  the
provisions of this  Agreement,  shall be reimbursed by the  Partnership  for all
reasonable  direct and  indirect  costs and  expenses  incurred on behalf of the
Partnership in the performance of their duties  hereunder in accordance with the
Accounting Procedures attached hereto as Exhibit B.



                                   ARTICLE VI
                            RELATIONS OF THE PARTNERS

         6.1      Restricted Transactions.

         (a) Except as set forth in Section  6.1(a)(i) below,  during the period
of time that a person is a Partner, no Partner shall, nor shall it to the extent
possible  permit  its  Affiliates  to,  engage  in any  transactions  involving,
directly or indirectly  any business  activity  which is within the scope of the
business  activities of any NOARK Related  Entity as established by the Partners
pursuant to Section 3.5(f) (a "Restricted Transaction") without first giving the
Partnership a right of first  refusal in accordance  with the terms set forth in
Section  6.1(b)  below with  respect to such  Restricted  Transaction.  Any such
business  activities of any NOARK Related  Entity so established by the Partners
shall be restricted to business activities on the System.

                  (i) A person who is a  Partner,  or who is an  Affiliate  of a
Partner,  shall be permitted  to (u) conduct gas  marketing  activities  without
restriction,  (v) continue to own and/or  operate  facilities for the gathering,
transportation,  processing,  compression  or storage  of natural  gas or liquid
hydrocarbons  which  they  owned  and/or  operated  on  December  31,  1997 (the
"Existing  Facilities"),  (w) continue to conduct  transactions  involving  such
Existing  Facilities,  (x) expand and extend such  facilities (by  construction,
purchase or otherwise) and  transactions  involving  such  facilities (y) expand
and/or extend those  businesses or operations and (z) conduct any other business
activities  which are not  conducted  on the  System.  It is the  intent of this
Section  (6)(a)(i) to permit Partners and their Affiliates to continue to engage
in those  businesses  and operations (in which they were engaged on December 31,
1997) and to expand and/or extend those businesses and operations.  Any projects
or businesses,  however,  which do not involve such  businesses or operations as
they

                                       27

<PAGE>



may be so expanded or extended and which would  otherwise meet the  requirements
of Section 6.1(a), are to be offered to the Partnership under Section 6.1(b).

         (b)  Should  any  Partner  or  its  Affiliate  desire  to  engage  in a
Restricted Transaction,  such Partner (the "Submitting Partner") shall submit to
the  Partnership  and to each Partner  written  notice (a  "Submission")  of the
Restricted  Transaction,  including a copy of any contract or agreement  setting
forth the terms of the Restricted  Transaction.  The Partnership (whether itself
or through a NOARK Related Entity) acting upon the unanimous approval of all the
Partners  except the Submitting  Partner (who shall have no right to vote on the
Restricted  Transaction) shall then have sixty (60) days from the delivery to it
of the Submission in which to elect to pursue the Restricted  Transaction on the
terms set forth in the Submission.  The Partnership  shall evidence its election
to pursue the  Restricted  Transaction by giving written notice of such election
to the Submitting  Partner within such sixty (60) day period, and the Submitting
Partner shall no longer have any separate interest in the Restricted Transaction
but shall fully  cooperate in assisting the Partnership to pursue the Restricted
Transaction.  If the Partnership does not elect in a timely manner to pursue the
Restricted  Transaction,  then the Partnership  shall be deemed to have rejected
the Restricted  Transaction  and the Submitting  Partner shall be free to pursue
the Restricted  Transaction for its own separate  account;  provided,  that, the
terms upon which the Submitting Partner shall pursue the Restricted  Transaction
shall be the same as those set forth in the  Submission to the  Partnership.  If
the terms of the Restricted  Transaction  shall vary from those set forth in the
Submission,  then the Submitting Partner shall be required to commence again the
right of first refusal process by submitting a new Submission  setting forth the
revised terms to the Partnership and the Partners and the Partnership shall have
the right to accept or reject the Restricted  Transaction in accordance with the
procedure set forth in this Section 6.1 (b).

         (c) Subject to the  restrictions  contained in Section 6.1(a),  (i) the
Partners recognize that each of the Partners, directly or through its respective
Affiliates,  may be currently engaged in numerous businesses in the gas industry
including,  without  limitation,   buying,  selling,  gathering,   transporting,
processing,  compressing  or  storing  natural  gas or liquid  hydrocarbons  for
profit;  and (ii) each Partner  agrees that each other Partner may continue such
activities, may form new Affiliates to engage in such activities, and may expand
the present scope of such activities,  in each case irrespective of whether such
be deemed in competition  with the business and  activities of the  Partnership,
without in any  manner  being  obligated  to  disclose  such  activities  to the
Partnership or the other Partners,  or to permit the Partnership or the Partners
to  participate  therein,  and without any liability to the  Partnership  or the
Partners for breach of any duty arising out of such other Partner's  position as
a Partner in the Partnership.

         6.2      Exculpation from Liability.

         (a) The  Project  Leader,  shall have no  liability  whatsoever  to the
Partnership  (including  any NOARK  Related  Entity) or to any  Partner for loss
caused  by any act or by  failure  to do any  act if the  loss  suffered  by the
Partnership (including any NOARK Related Entity) or any Partner arises out of an
action  taken,  or not  taken,  by the  Project  Leader  in  the  course  of the
Partnership's

                                       28

<PAGE>



(including any NOARK Related Entity)  business in good faith and not contrary to
the terms of this  Agreement  even if such action or failure to act  constitutes
negligence.

         (b) Neither the  Management  Committee,  nor any member  thereof (other
than  the  Project  Leader  to whom  Section  6.2(a)  applies),  shall  have any
liability whatsoever to the Partnership  (including any NOARK Related Entity) or
to any  Partner  for loss  caused by any act or by  failure to do any act if the
loss suffered by the  Partnership  (including  any NOARK Related  Entity) or any
Partner arises out of an action taken, or not taken by the Management Committee,
or a member  thereof in the  course of the  Partnership's  (including  any NOARK
Related  Entity)  business  in good faith and not  contrary to the terms of this
Agreement even if such action or failure to act constitute negligence; provided,
that,  this  shall  not apply  where  the  Person's  action  or  failure  to act
constitute willful misconduct or gross negligence.

         6.3      Indemnification.

         (a)  To  the  fullest  extent  permitted  by  law  but  subject  to the
limitations  expressly  provided in this  Agreement,  each  Indemnitee  shall be
indemnified  and held harmless by the  Partnership  (including any NOARK Related
Entity) from and against any and all losses, claims, damages, liabilities (joint
or several),  expenses (including without limitation,  reasonable legal fees and
expenses),  judgments, fines, settlements and other amounts arising from any and
all claims,  demands,  actions,  suits or proceedings,  whether civil, criminal,
administrative  or  investigative  (other  than  claims  by or on  behalf of the
Partnership, including any NOARK Related Entity), in which any Indemnitee may be
involved, or is threatened to be involved, as a party or otherwise, by reason of
its status as an  Indemnitee  arising out of or relating to the  performance  of
this  Agreement or its actions (or failures to act) with respect to the business
of the Partnership (including any NOARK Related Entity);  provided, that in each
case the  Indemnitee  acted in good  faith,  in a manner  which such  Indemnitee
believed  to be in, or not  opposed to, the best  interests  of the  Partnership
(including  any  NOARK  Related  Entity)  and,  with  respect  to  any  criminal
proceeding,  had no reasonable  cause to believe its conduct was  unlawful.  The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction  or upon a plea of nolo  contendere,  or its  equivalent,  shall  not
create a  presumption  that the  Indemnitee  acted in a manner  contrary to that
specified above.

         (b) To the fullest extent permitted by law, expenses (including without
limitation,  reasonable  legal fees and  expenses)  incurred by an Indemnitee in
defending any claim,  demand,  action,  suit or proceeding  shall,  from time to
time, be advanced by the Partnership  (including any NOARK Related Entity) prior
to the final disposition of such claim, demand,  action, suit or proceeding upon
receipt by the  Partnership  of an undertaking by or on behalf of the Indemnitee
to repay  such  amount  if it shall be  determined  that the  Indemnitee  is not
entitled to be indemnified as authorized in this Section 6.3.

         (c) The  indemnification  provided  by this  Section  6.3  shall  be in
addition to any other rights to which an Indemnitee  may be entitled  under this
Agreement, as a matter of law or otherwise,

                                       29

<PAGE>



as to actions in the  Indemnitees'  capacity as an Indemnitee and shall continue
as to an  Indemnitee  who has  ceased to serve in such  capacity  as to  actions
during its capacity as an Indemnitee.

         (d) The  Partnership  shall  purchase  and  maintain  insurance  on the
Partnership  (including  the  NOARK  Related  Entities)  and the  assets  of the
Partnership  (including any NOARK Related  Entities).  Such insurance shall at a
minimum include the insurance  specified on Schedule 6.3(d) attached hereto. The
Partnership  may purchase and maintain  insurance  (in such amounts and for such
purposes as the Partnership  shall  determine),  on behalf of the Partners,  the
Project  Leader  and such  other  Persons as the  Partnership  shall  determine,
against  any  liability  that may be  asserted  against or  expense  that may be
incurred by any such Person in  connection  with the  Partnership's  activities,
whether or not the  Partnership  would have the power to  indemnify  such Person
against such liabilities under the provisions of this Agreement.

         (e) In no event may an Indemnitee subject a Limited Partner to personal
liability  by  reason  of the  indemnification  provisions  set  forth  in  this
Agreement.

         (f) An Indemnitee  shall not be denied  indemnification  in whole or in
part under this  Section  6.3  because  the  Indemnitee  had an  interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement.

         (g) The  provisions  of this  Section  6.3 are for the  benefit  of the
Indemnitees,  their heirs, successors,  assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.

         (h) No  amendment,  modification  or repeal of this  Section 6.3 or any
other provision hereof shall in any manner terminate, reduce or impair the right
of any Indemnitee,  or former Indemnitee,  to be indemnified by the Partnership,
nor the obligation of the Partnership to indemnify any such Indemnitee under and
in accordance  with the provisions of this Section 6.3 as in effect  immediately
prior to such  amendment,  modification or repeal with respect to claims arising
from or  relating  to  matters  occurring,  in whole  or in part,  prior to such
amendment modification or repeal, regardless of when such claims may arise or be
asserted.

(including  any NOARK  Related  Entity),  whether  real,  personal  or mixed and
whether  tangible or intangible,  shall be deemed to be owned by the Partnership
as an entity,  and no  Partner,  individually  or  collectively,  shall have any
ownership  interest in such assets of the  Partnership  or any portion  thereof.
Title  to any or all of the  assets  of the  Partnership  (including  any  NOARK
Related Entity) may be held in the name of the Partnership  (including any NOARK
Related  Entity),  or one or  more  nominees  as the  Management  Committee  may
determine  under  the terms of a nominee  agreement  the form of which  shall be
approved  by a  SuperMajority  in Interest  of the  Partners.  All assets of the
Partnership  (including  any NOARK  Related  Entity)  shall be  recorded  as the
property of the  Partnership in its books and records,  irrespective of the name

                                   ARTICLE VII
                      ASSIGNABILITY OF PARTNERS' INTERESTS

         7.1 Restrictions on Transfer of Partner's Interest. Except as set forth
in Section  7.7, no Partner  may  Transfer  all or a portion of its  Partnership
Interest  (the   "Transferor"),   unless  the  Transferor  and  transferee  (the
"Transferee"),  comply  with the  provisions  of  Section  7.2.  No portion of a
Partner's  right to  receive  its  allocable  share of  income  and  losses  and
distributions of the Partnership may be Transferred  without the Transfer of the
same  portion of a Partner's  Partnership  Interest.  Failure to comply with the
provisions of this Article VII shall render the purported Transfer null and void
and of no force or effect for any purpose.

         7.2 Right of First Refusal. At any time, a Transferor may offer to sell
for cash all or a portion of its Partnership  Interest (but any such portion may
not be less than ten percent (10 %) of the total Partnership Interests)to any or
all of the other  Partner(s)  by  delivering to them a written offer (the "Sales
Offer")  specifically  referring to this Section 7.2,  stating the  Transferor's
desire to sell, specifying the portion of such Partnership Interest to which the
Sales Offer applies, stating that such portion is to be sold in its entirety and
setting forth the cash  purchase  price.  Within thirty (30) days  following the
receipt of the Sales  Offer,  each other  Partner  may elect to accept the Sales
Offer  at  the  purchase  price  set  forth  therein.  Such  acceptance  may  be
conditioned upon approval by the board of directors of the accepting  Partner to
be obtained  within sixty (60) days following  receipt of the Sales Offer by the
accepting  Partner.  If more than one of the other  Partners elect to accept the
Sales  Offer,  the  purchase  shall  be made  pro  rata in  accordance  with the
accepting  Partners'  respective   Partnership   Interests.   Payment  for  such
Partnership  Interest shall be made within thirty (30) days after the final date
on which a Partner elects to accept the Sales Offer;  provided,  however, if any
waiting periods are imposed by applicable law,  payment shall, if necessary,  be
deferred to the first  business day occurring  after the  expiration of the last
day of such  waiting  period.  In the event  that the  Partners  do not elect to
acquire  or do not  acquire  the  entire  portion  of the  Partnership  Interest
specified  in a Sales  Offer  within the time  periods  referred  to above,  the
Transferor  shall  be  entitled  to  Transfer  to a third  party  (including  an
Affiliate of the Transferor) the Partnership  Interest stated in the Sales Offer
for a consideration in cash or other property having equal or greater value than
the cash  purchase  price  stated in the Sales  Offer  during  the six (6) month
period  commencing  with the day  following  the  expiration  of the 60-day time
period  referred  to above.  If the  consideration  is other than all cash,  the
Transferor  shall  provide  the other  Partners  with the report of a  qualified
appraiser  concluding that the total value of the  consideration  to be paid for
the  Partnership  Interest is equal to or exceeds the value of the cash purchase
price stated in the Sales Offer. Prior to any Transfer becoming  effective,  the
Transferor  shall provide written notice to all of the Partners and shall settle
all unpaid accounts with the Partnership.

         7.3 Opinion of Counsel.  The  Transferor  shall  deliver to the Project
Leader evidence  satisfactory to the Project Leader (including,  if requested by
the Project Leader an opinion of counsel in form and substance  satisfactory  to
counsel to the Partnership), that:


                                       31

<PAGE>



         (a) such Transfer and any offerings made in connection therewith are in
compliance with applicable federal and state securities laws; and

         (b) the Transfer will comply with all applicable  rules and regulations
of government authorities.

         (c) such Transfer and offerings will not cause the  Partnership to be a
publicly traded partnership within the meaning of Section 7704 of the Code.

         7.4  Substituted  Partner.  A  Transferee  shall  become a  Substituted
Partner of the  Partnership  in the event a  SuperMajority  in  Interest  of the
Partners consent in writing to the Transferee  becoming a Substituted Partner or
if the Transferor and Transferee  have complied with all of the  requirements of
this Article VII and:

         (a) The  Transferor  states  its  intention  in  writing  to  have  the
Transferee  become  a  Substituted  Partner  as  concerns  the  portion  of  its
Partnership Interest to be Transferred;

         (b) The Transferee  agrees to pay any filing fees,  reasonable  counsel
fees, and other  reasonable  expenses of the  Partnership in connection with its
becoming a Substituted Partner;

         (c) The  Transferee  agrees in  writing to be bound by all of the terms
and provisions of the Agreement and any other document or instrument executed by
or otherwise  binding upon the Partners as if an original party to the Agreement
or other such document or instrument  and to assume all the duties,  liabilities
and  obligations  of the  Transferor  in respect of such  Partnership  Interest,
provided,  that, the Transferor shall not be released from any liabilities of or
to the Partnership arising prior to the date of the Transfer; and

         (d) The  Transferee  executes a statement  satisfactory  to the Project
Leader that it is acquiring  such  Partnership  Interest for its own account for
investment and not with a view to the distribution or resale thereof.

         7.5 Recognition of Transferee as Partner.  Upon the effective  Transfer
of a Partnership Interest,  compliance with the other provisions of this Article
VII, and  admission of the  Transferee  as a  Substituted  Partner,  the Project
Leader shall,  to the extent  required by law execute,  file and record with the
appropriate  governmental  agencies such documents as are required to accomplish
the substitution of the Transferee as a Substituted Partner. If required by law,
the  Certificate of Limited  Partnership  shall be amended and recorded not more
often than  quarterly,  to  recognize  the  admission of  Substituted  Partners.
Nothing  contained  herein is meant to require  the filing of a  Certificate  of
Limited  Partnership  (or  amendment  thereto)  which  includes the names of all
Partners and Substituted  Partners,  if under applicable state law the inclusion
of such names is  discretionary.  In all events the Project  Leader  shall amend
this Agreement to reflect the admittance to the  Partnership of the  Substituted
Partner.  The  Partnership  shall treat a Transferee  who becomes a  Substituted
Partner pursuant to the provisions of this Article VII as a Substituted  Partner
with respect

                                       32

<PAGE>



to the Partnership  Interest,  or part thereof,  assigned from the last business
day of the calendar  quarter  following the  acceptance by the Project Leader of
the  Transfer,  notwithstanding  the time  consumed in preparing  and filing the
necessary  documents  with  governmental  agencies  necessary to effectuate  the
substitution.

         7.6 Binding  Effect.  Any Transferee  admitted to the  Partnership as a
Substituted  Partner shall be subject to and bound by all the  provisions of the
Agreement as if an original party to the Agreement.

         7.7 Permitted Transfers of Partnership  Interests.  Notwithstanding any
provision of this Article VII or the  Agreement to the  contrary,  a Partner may
transfer its Partnership Interest in accordance with the following, provided the
transfer does not cause a termination  of the  Partnership  under Section 708 of
the Code:

         (a)  any  Partner  may  transfer  all or any  part  of its  Partnership
Interest to its Affiliate,  which is directly or indirectly  wholly-owned by the
Partner;  provided such wholly-owned Affiliate complies with the requirements of
Section 7.4 and that, any such transfer shall not relieve the assigning  Partner
of any of its past or future obligations under this Agreement;

         (b) the  Partners may pledge or otherwise  encumber  their  Partnership
Interests  to  secure  indebtedness  of  the  Partnership  or of  the  Partners;
provided, that, any Person who acquires a Partnership Interest by reason of such
pledge  or  encumbrance  shall  not in any event be  admitted  as a  Substituted
Partner unless approved in writing by a SuperMajority in Interest.

         7.8  Succession  to  Capital   Account.   Any  valid  Transferee  of  a
Partnership  Interest  in  accordance  with the  terms of this  Agreement  shall
succeed to the balance of its Transferor's Capital Account.



                                  ARTICLE VIII
                             WITHDRAWAL AND REMOVAL;
             ADMISSION OF SUCCESSOR AND ADDITIONAL GENERAL PARTNERS

         8.1  Voluntary  Withdrawal.  Each  Partner  hereby  agrees  that it may
withdraw from the Partnership only in connection with a Transfer of the entirety
of its  Partnership  Interest in accordance  with Article VII hereof or with the
prior written consent of all other Partners.  Any withdrawal not permitted under
the  preceding  sentence  shall  constitute  a breach of this  Agreement  by the
withdrawing Partner.

         8.2  Other  Withdrawal  Events.  The  occurrence  of any of the  events
described  in  Subsection  4-43-402(4)  and (5) of the Act shall not  effect the
withdrawal of a General Partner.


                                       33

         8.3      Removal of a Partner.  A Partner may not be removed as a 
Partner.

         8.4 Liability of a Withdrawn General Partner. Any General Partner which
shall for any reason  withdraw  from the  Partnership,  whether  voluntarily  or
involuntarily,  or shall Transfer all or a portion of its Partnership  Interest,
shall be and remain liable for all obligations and liabilities  incurred by such
General Partner  (including  liabilities of the Partnership or any NOARK Related
Entity) prior to the time such withdrawal or Transfer has become effective,  but
shall  be free  of any  obligation  or  liability  incurred  on  account  of the
activities of the  Partnership  (including  any NOARK  Related  Entity) from and
after the time such  withdrawal  or Transfer  becomes  effective  except for any
liabilities  or  damages  attributable  to its  action in  withdrawing  from the
Partnership.

         8.5      Additional or Successor Partners.

         (a) The Management  Committee may admit additional or successor General
Partners in connection  with a Transfer of all or a part of a General  Partner's
Partnership Interest subject to compliance with Article VII above.

         (b) If a General  Partner  withdraws  pursuant to this Agreement and if
such removal would leave the Partnership  without a General Partner,  then prior
to the effective date of such removal or withdrawal,  the Limited Partners shall
meet to select and appoint one or more  successor  General  Partners to continue
the  business of the  Partnership,  which  selection  and  appointment  shall be
effected by the  approval of a Majority in Interest of the Limited  Partners and
become effective prior to the removal or withdrawal of a sole General Partner. A
one percent (1%)  partnership  interest  shall be  reallocated  from the Limited
Partners,  pro rata, to any successor  General  Partner(s)  required pursuant to
this  Section  8.5,  unless  the  successor  General  Partner  makes  a  capital
contribution to the Partnership equal to or greater than one percent (1%) of the
total of the Capital Contributions to the Partnership.

         8.6 Continuation of Partnership.  In the event of an event which causes
the  dissolution of the  Partnership by the  provisions of this  Agreement,  the
Partnership may be reconstituted and its business  continued without being wound
up by the agreement in writing of all Partners.

         8.7  Automatic  Suspension  of the Vote and  Right  to  Participate  in
Management of  Partnership  Affairs:  A Partner's  right to  participate  in the
management  of  Partnership  affairs  shall be  suspended  in the  event of such
Partner's  failure  to make a capital  contribution  required  to be made  under
Section 4.2 above,  when such  failure  continues  for a period of ten (10) days
following receipt of notice from the Project Leader of such failure to make such
capital contribution; provided, however, if the capital contribution required to
be made is  being  disputed  by such  Partner  in  good  faith  and the  Partner
contributes  that portion,  if any, of the capital  contribution not in dispute,
such Partner's  right to  participate  in the management of Partnership  affairs
shall not be suspended.

         (a)      upon the expiration of its term as provided in Section 2.4;

         (b)      upon the approval of a SuperMajority in Interest of the
Partners pursuant to Section 3.5; and

         (c) upon any other event that, under this Agreement or Section 4-43-801
of the Act,  causes its  dissolution,  except that an event of  withdrawal  of a
General  Partner shall not cause a dissolution of the  Partnership  unless there
are no  remaining  General  Partners  and the Limited  Partners do not appoint a
successor General Partner in accordance with Section 8.5 hereof.

         9.2  Liquidation.  Upon  dissolution  of the  Partnership,  unless  the
Partnership  is continued  pursuant to the  provisions  of this  Agreement,  the
Liquidator shall proceed with the winding up of the business and the liquidation

         10.1     Liquidation and Termination.

         (a) In the event of the  dissolution  of the  Partnership in accordance
with Section 9.1 above, unless the remaining Partners, if any, elect to continue
the business of the Partnership as provided by the terms of this Agreement,  the
Liquidator of the  Partnership  shall proceed with the winding up of the affairs
of the Partnership.  Upon the dissolution of the Partnership no further business
shall be conducted, except for such action as shall be necessary for the winding
up of the affairs of the Partnership  and the  distribution of its assets to the
Partners pursuant to the provisions of this section.  The Liquidator may appoint
in writing one or more  liquidating  trustees  who shall have full  authority to
wind up the  affairs  of the  Partnership  and to  make  final  distribution  as
provided herein.

         (b) Upon dissolution of the Partnership, the Liquidator may sell any or
all Partnership  property at the best price available or it may distribute those
properties in kind at their Gross Asset Values. Any Partner or an Affiliate of a
Partner may purchase Partnership property upon liquidation following thirty (30)
days prior public  notice of the proposed  sale.  The price paid by a Partner or
its Affiliates for any  Partnership  property shall in no event be less than the
greater of (i) the  highest  bid  received  from a third  party or (ii) the fair
market  value of such  property  as  determined  by an  independent  third party
appraiser.

<PAGE>



         (c) The  Liquidator  shall  apply  and  distribute  the  assets  of the
Partnership as follows:

                  (i)  First,  to  the  payment  and  discharge  of  all  of the
Partnership's  debts and liabilities to creditors,  including the Existing Loans
but excluding other debts to the Partners;

                  (ii)  Second,  to  the  payment  and  discharge  of all of the
Partnership's other debts and liabilities to the Partners.

                  (iii)  Third,   after  giving  effect  to  all  contributions,
distributions  and  allocations  for taxable years including the taxable year in
which the  liquidation  occurs,  to the Partners in accordance with the positive
balances in their respective Capital Accounts; and

                  (iv)  The  balance,   if  any,   according  to  the  Partners'
respective Partnership Percentages.

         10.2 Capital  Account  Deficits.  If any General  Partner has a deficit
balance  in its  Capital  Account  (after  giving  effect to all  contributions,
distributions  and allocations for all taxable years,  including the year during
which such  liquidation  occurs  and  Sections  10.1(c)(i)  through  (iii),  but
excluding Section 10.1(c)(iv)) at the time of the dissolution and liquidation of
the  Partnership,  such General  Partner shall  contribute to the capital of the
Partnership  the amount  necessary to restore  such  deficit  balance to zero in
compliance with Treas. Reg. ss. 1.704-1(b)(2)(ii)(b)(3).  If any Limited Partner
has a  deficit  balance  in its  Capital  Account  (after  giving  effect to all
contributions,  distributions  and allocations for all taxable years,  including
the year during which such liquidation  occurs and Sections  10.1(c)(i)  through
(iii),  but excluding  Section  10.1(c)(iv))  such Limited Partner shall have no
obligation  to make any  contribution  to the  capital of the  Partnership  with
respect to such deficit, and such deficit shall not be considered a debt owed to
the Partnership or to any other Person for any purpose whatsoever.

         10.3 Special  Distributions.  In the  discretion of the  Liquidator,  a
portion of the  distributions  that would  otherwise  be made  pursuant  to this
Article X may be:

         (a) distributed to a trust  established for the benefit of the Partners
for the purposes of liquidating  Partnership assets,  collecting amounts owed to
the  Partnership,  and  paying  any  contingent  or  unforeseen  liabilities  or
obligations  of  the  Partnership.  The  assets  of  any  such  trust  shall  be
distributed to the Partners from time to time, in the  reasonable  discretion of
the Liquidator,  in the same proportions as the amount distributed to such trust
by the  Partnership  would  otherwise  have  been  distributed  to the  Partners
pursuant to this Agreement; or

         (b)   withheld  to  provide  a  reasonable   reserve  for   Partnership
liabilities  (contingent or otherwise) and to reflect the unrealized  portion of
any installment obligations owed to the Partnership, provided that such withheld
amounts shall be distributed to the Partners as soon as practicable.

         10.4 Deemed Distribution and Recontribution.  Notwithstanding any other
provision of this Article X, in the event the  Partnership is liquidated  within
the  meaning  of  Treas.  Reg.  ss.  1. 704-  1(b)(2)(ii)(g)  (regarding  when a
liquidation occurs) but it has not dissolved pursuant to Section 9.1 hereof, the
Partnership shall not be liquidated,  the Partnership's liabilities shall not be
paid or  discharged,  and the  Partnership's  affairs  shall  not be  wound  up.
Instead,  pursuant to Treas.  Reg. ss.  1.708-1(b)(1)(iv),  the  Partnership for
federal  income  tax  purposes  shall be deemed to have  contributed  all of its
property and  liabilities  to a new  partnership  in exchange for a  partnership
interest in such new partnership pursuant to Treas. Reg. ss.  1.708-1(b)(1)(iv).
Immediately thereafter, the Partnership for federal income tax purposes shall be
deemed to have  distributed the interests in the new partnership to the Partners
in proportion to their interests as if the Partnership were liquidated.

         12.1 Books of Account.  The Partners intend that the Partnership  shall
be a  partnership  for  federal,  state and local income tax purposes and to the
extent  possible  for federal,  state and local  income tax purposes  each NOARK
Related   Entity   will  be   treated   as  set   forth  in  Treas.   Reg.   ss.
301.7701-3(b)(1)(ii).  Each Partner agrees not to make the election described in
Section  761  (a) of  the  Code  to be  excluded  from  the  application  of the
provisions  of  Subchapter  K of Chapter I of Subtitle A of the Code.  Moreover,
each Partner agrees not to make an election to be excluded from the  partnership
provisions of any  applicable  state or local taxation  statute.  The Management
Committee  shall, to the extent  permissible  under existing law, for income tax
purposes,  keep or  cause  to be kept on an  accrual  basis,  adequate  books of
account of the Partnership  wherein there shall be recorded and reflected all of
the  Capital  Contributions  and all of the  expenses  and  transactions  of the
Partnership.  Such  books of  account  shall be kept at the  principal  place of
business of the Partnership (or at the place where  accounting  services for the
Partnership are performed),  and each Partner and his authorized representatives
shall have at all times,  during  reasonable  business hours, free access to and
the right to  inspect  and copy such  books of  account  and all  records of the
Partnership,  including  the right to obtain by mail or to inspect a list of the
names and addresses and Partnership  Interests owned by the Partners.  All books
and  records  of the  Partnership  shall  be  kept  on the  basis  of an  annual
accounting  period ending  December 31, except for the final  accounting  period
which shall end on the  dissolution or termination  of the  Partnership  without
reconstitution.  Accelerated  methods  of  depreciation  may be  elected  by the
Partnership  with  respect to its assets for  purposes of  reporting  federal or
state taxes.

         12.2 Reports and Financial  Statements.  The Partner who is maintaining
the accounting  records of the Partnership shall maintain a system of accounting
established and  administered in accordance with Generally  Accepted  Accounting
Principles  and FERC  system  of  accounts,  as  applicable,  shall  maintain  a
calculation of Capital  Accounts  according to the terms of this Agreement,  and
shall provide the following reports and financial statements to the Partners:

commencing  at the end of the  previous  fiscal  year and ending with the end of
such month, all in reasonable detail; and

         (c) Income Tax  Information.  Within one hundred  sixty-five (165) days
after the end of each  calendar  year,  the  Partnership  will also furnish each
Partner (and each transferee of a Partnership Interest who shall have not become
a Substituted  Partner) with the required income tax information  based upon the
Partnership's  tax return  which will be prepared and filed with the Service and
other applicable  taxing  authorities.  Within ninety (90) days after the end of
each  calendar  year,  the  Partnership  will  furnish to each Partner (and each
transferee  of a  Partnership  Interest who shall have not become a  Substituted
Partner) an estimate of the required income tax information.

         12.3  Tax  Returns  and  Other  Reports.  The  Project  Leader,  at the
Partnership's  expense, shall cause income tax returns for the Partnership to be
prepared and timely filed with the appropriate authorities.  The Project Leader,
at  Partnership  expense,  shall cause to be  prepared  and timely  filed,  with
appropriate federal and state regulatory and administrative  bodies, all reports
required to be filed with such  entities  under then  current  applicable  laws,
rules and  regulations.  Such  reports  shall be prepared on the  accounting  or
reporting  basis  required  by such  regulatory  bodies.  Any  Partner  shall be
provided with a copy of any such report upon request without expense to it.

         12.4 Fiscal Year. The fiscal year of the  Partnership  shall begin with
the first day of January and end on the last day of December in each year.

safekeeping  and use of all  funds  of the  Partnership,  whether  or not in his
immediate possession or control, and he shall not employ such funds or assets in
any manner except for the exclusive benefit of the Partnership.

         12.6 Tax Elections.  The Partnership shall make the following elections
under the Code and Treasury  Regulations and any similar state or local statutes
subject to  modification  at the direction of the  Management  Committee  (which
modification shall be subject to any applicable Partner approvals required to be
obtained under Section 3.5):

         12.8  Survival  of Tax  Provision.  The  provisions  of  the  Agreement
relating to tax matters shall survive the  termination  of the Agreement and the
termination  of any Partner's  Partnership  Interest and shall remain binding on
that  Partner  for the  period of time  necessary  to  resolve  any tax  matters
regarding the Partnership with any federal, state and local tax authority.

         12.9 Deposit of Funds.  Funds of the Partnership  shall be deposited in
such banks or other  depositories  as shall be designated by the Project Leader.
Pending the application of such funds to the cash needs of the Partnership,  the
Partnership's funds shall, to the extent practicable,  be continuously invested.
Funds  of the  Partnership  may  only  be  placed  in  the  following  types  of
investments;  provided,  that such  investments  shall not  preclude  the timely
distribution  of excess cash;  and  provided,  further,  that any  investment of
working  capital  shall not  preclude  the timely  payment of the  Partnership's
obligations when and as due:

                  12.9.1   Cash in the form of U.S. currency.

                  12.9.2  Evidence of  indebtedness,  maturing not more than one

         Partnership  maintains its  operating  accounts or with a related trust
         company.

                  12.9.4 Such other investments as the members on the Management
         Committee   representing   the  General  Partners  shall  determine  by
         unanimous decision.


                                  ARTICLE XIII
                               DISPUTE RESOLUTION

         13.1 Invoking Procedure. In the event of a dispute between the Partners
arising  out of or related to this  Agreement  or  related  to the  business  or
affairs of the  Partnership,  or in the event a SuperMajority in Interest of the
Partners do not agree on a matter  requiring  such approval under Section 3.5 of
this Agreement and such lack of approval  results in a Stalemate (as hereinafter
defined in Section 13.2), either Partner may invoke the procedures  specified in
this Article by giving written notice to the other Partners. Such written notice
will  describe  briefly  the  nature of the  dispute,  or the  matter  for which
approval  has not been  obtained  under  Section  3.5,  and  shall  identify  an
individual  with  authority  to settle such  dispute or matter on behalf of that
Partner. The Partner receiving such notice shall have ten (10) days within which
to designate an  individual  with  authority to settle such dispute or matter on
its behalf and to give written  notice to the other  Partner of its  designation
(the  individuals  so  designated  shall  be  referred  to  as  the  "Authorized
Individuals").  Unless  otherwise  notified,  the Authorized  Individual of each
Partner shall be its  President.  For purposes of this Section 13.1,  any matter
which would  otherwise be a Stalemate if a meeting of the Partners had been held
and requisite SuperMajority in Interest approval not obtained, or a proposal

                                       42

<PAGE>



submitted pursuant to Section 3.4(e) and the requisite SuperMajority in Interest
approval not given,  shall be deemed ripe for resolution under this Article XIII
if the  proponent  has (i) called a meeting of the  Partners and has included in
the  Agenda  included  with  the  notice  of the  meeting  a full  and  complete
description of the proposal along with all information reasonably required for a
determination or vote by the other Partners(s) and the other Partner(s) does not
attend the meeting and does not, prior to the time scheduled therefor, request a
postponement  or  adjournment  thereof for up to ten days, or if the  Partner(s)
requests such a postponement  or  adjournment  but does not attend the postponed
meeting  or a new  Partner  meeting  within  such ten (10) day  period,  or (ii)
submitted such proposal to the other Partner(s) for approval pursuant to Section
3.4(e)  hereof and such other  Partner(s)  does not provide such consent  within
fifteen (15) days from the later of its receipt of such request or the date that
it shall receive all additional  information regarding such proposal that it may
have  reasonably  requested in a written  notice  submitted to the proponent not
more than ten (10) days after the  receipt of the  proponent's  request for such
consent.

         13.2  Stalemate   Defined.   For  purposes  of  this  Article  XIII,  a
"Stalemate"  shall mean any situation in which one or more  proposals  have been
submitted  to the  Partners  relating  to action  reasonably  considered  by the
proponent to be required to be taken by the  Partnership,  or the Project Leader
on behalf of the Partnership,  in order to avoid or substantially mitigate (i) a
cessation  of, or  material  disruption  or  impediment  in, the  conduct of its
ongoing  operations  and  affairs  to any  material  extent,  or (ii)  potential
material harm or damage to the Partnership, its business,  operations,  affairs,
properties or other assets,  but which  proposal or proposals are not able to be
implemented because there has not been an approval thereof by a SuperMajority in
Interest of the Partners as required by Section 3.5. In this regard, the failure
to approve a Budget by the end of the first quarter of a fiscal year to which it
relates and which has been presented to the Partners in material compliance with
Section  3.6(g) hereof shall be considered to be a Stalemate and approval of the
Budget,  or specific  items thereof which are then in dispute,  as then proposed
may be presented for dispute resolution pursuant to this Article XIII.

         13.3  Investigation.  The  Authorized  Individuals  shall make whatever
investigation each deems appropriate and promptly thereafter,  but no later than
thirty (30) days from the date of the original notice invoking these procedures,
shall commence  discussions  concerning  resolution of the dispute or matter. If
the dispute or matter has not been resolved within sixty (60) days from the date
of the original notice invoking these procedures,  the Partners shall submit the
dispute or matter to ADR in accordance with the following procedure.

         13.4 Neutral. The Partners shall have ten (10) days from the expiration
of the sixty (60) day period referred to in Section 13.2 above, or the agreement
of the Partners, to submit the dispute or matter to ADR, whichever occurs first,
within  which to agree upon a mutually  acceptable  person not  affiliated  with
either  party  ("Neutral").  If no Neutral  has been  selected  within that time
period,  the  Partners  agree  jointly  to  request  the  American   Arbitration
Association or other  mutually  agreed-upon  organization,  to supply within ten
(10) days a list of at least three (3) potential Neutrals with qualifications as
specified by the Partners in the joint request. Within seven (7) days of receipt
of the

                                       43

<PAGE>



list, the Partners shall rank the proposed  candidates  independently,  exchange
rankings  and select as the  Neutral the  individual  who  received  the highest
combined ranking who is available to serve.

         13.5 Schedule.  In  consultation  with the Neutral,  the Partners shall
designate  a  mutually  convenient  time  and  place  for the  ADR,  and  unless
circumstances  require  otherwise,  such time shall be not later than forty-five
(45) days after the selection of the Neutral.

         13.6 Discovery. In the event one or both Partners have substantial need
for information in the possession of the other Partner or a need to take certain
limited depositions and/or production of principal documents in order to prepare
for the ADR, the Partners shall attempt in good faith to agree on a plan for the
expeditious  exchange of such information.  Should they fail to reach agreement,
either  Partner may request a meeting  with the Neutral who shall assist them in
reaching an accommodation.

         13.7 Written Submission.  One week prior to the first scheduled session
of the ADR, each Partner shall deliver to the Neutral and to the other Partner a
written  summary  of its views on the  dispute or matter in issue.  The  summary
shall be no longer than  twenty (20)  double-spaced  pages  unless the  Partners
agree otherwise.

         13.8 Representatives.  In the ADR, each Partner shall be represented by
the Authorized  Individual and by counsel.  In addition,  each Partner may bring
additional   persons  as  necessary  to  respond  to  questions  or   contribute
information as needed. The number of such additional persons to be allowed shall
be mutually  agreed by the  Partners  with the  assistance  of the  Neutral,  if
necessary.

         13.9 Structure. The Neutral is authorized to conduct joint and separate
meetings with the Partners and to help the Partners  structure  whatever form of
presentation  of the  dispute  or matter in issue is most  likely to  facilitate
resolution.  Notwithstanding  the form of the presentation,  it is the intent of
the Partners to provide an opportunity for their Authorized Individuals, with or
without the assistance of counsel,  and with the  assistance of the Neutral,  to
negotiate  a  resolution  of the  dispute  or matter in issue.  In the event the
Neutral holds separate  private  caucuses with either  Partner,  he or she shall
keep  confidential  all  information  learned in such  private  caucuses  unless
specifically  authorized  to make  disclosure  of the  information  to the other
Partner.  There shall be no  stenographic,  visual,  or audio record made of the
ADR.

         13.10  Mandatory.  The Partners  agree to participate in the ADR to its
conclusion  as  designated  by the  Neutral  and not to  terminate  negotiations
concerning  resolution  of the dispute or matter in issue until at least two (2)
weeks thereafter.  Each Partner agrees not to commence arbitration or seek other
remedies prior to the conclusion of the two-week  post-ADR  negotiation  period,
provided that either  Partner may commence  arbitration  on any date after which
the  commencement  of  litigation  could be barred by an  applicable  statute of
limitations or in order to request an injunction to prevent irreparable harm. In
such event, the Partners agree (except as prohibited by court order) to continue
to participate in the ADR to its conclusion.

                                       44

<PAGE>



         13.11 Fees. The fees of, and authorized  costs incurred by, the Neutral
shall be advanced by the  Partnership  and shared  equally by the  Partners  who
shall reimburse the Partnership. The Neutral shall be disqualified as a witness,
consultant,  expert,  or counsel for any Partner  with respect to the dispute or
matter in issue and any related matters.

         13.12  Later  Proceedings.  The  ADR is a  compromise  negotiation  for
purposes of the Federal Rules of Evidence and the Rules of Evidence of the State
of Oklahoma.  The entire  procedure is  confidential.  All conduct,  statements,
promises,  offers,  views,  and opinions,  whether oral or written,  made in the
course  of  the  ADR  by  any  of  the  Partners,   their   agents,   employees,
representatives,  or other  invitees to the ADR and by the  Neutral,  who is the
parties'  joint agent for the  purposes of these  compromise  negotiations,  are
confidential and shall, in addition and where appropriate,  be deemed to be work
product and privileged. Such conduct,  statements,  promises, offers, views, and
opinions shall not be  discoverable  or admissible  for any purposes,  including
impeachment,  in any litigation or other  proceeding  involving the Partners and
shall not be disclosed to anyone not an agent,  employee,  expert,  witness,  or
representative  for any of the  Partners.  Evidence  otherwise  discoverable  or
admissible is not excluded from discovery or admission as a result of its use in
the ADR.

         13.13    Dispute Resolution

         (a) In the event the  Partners  are  unable to resolve  the  dispute or
matter in issue in accordance with the foregoing provision of this Article XIII,
the  dispute  or  matter  in issue  shall be  submitted  to  final  and  binding
arbitration.  The arbitration shall be administered by the American  Arbitration
Association  ("AAA") in accordance  with and in the following order of priority:
(i) the terms of these arbitration  provisions;  (ii) the Commercial Arbitration
Rules of the AAA;  (iii) the  Federal  Arbitration  Act  (Title 9 of the  United
States Code);  (iv) the Oklahoma  Uniform  Arbitration  Act (15 O.S. ss. 801, et
seq.);  and (v) to the extent the foregoing are  inapplicable,  unenforceable or
invalid,  the laws of the State of Oklahoma.  The validity and enforceability of
these  arbitration  provisions  shall be determined in accordance  with the same
order or priority.  In the event of any inconsistency  between these arbitration
provisions  and such rules and  statutes,  these  arbitration  provisions  shall
control.  Judgment  upon any award  rendered  hereunder  shall be entered in any
court having jurisdiction  thereof, and the parties' consent to the jurisdiction
of any state or  federal  court in  Oklahoma.  Commencement  of and  demand  for
arbitration  shall be made by written notice by the initiating  party (claimant)
to the other party  (respondent) which contains a statement of the nature of the
dispute or matter in issue,  the amount involved and the relief or remedy sought
("Notice").

         (b) The  arbitration  shall  be  conducted  by a  panel  of  three  (3)
arbitrators  (the  "Arbitration  Panel").  Each  Partner  will  nominate one (1)
arbitrator,  who is experienced and  knowledgeable  in the areas involved in the
dispute or matter in issue,  within ten (10)  working  days of their  receipt of
Notice that  arbitration  has been demanded and commenced,  and each will notify
the other  party of the name of its  selected  arbitrator  within that same time
period. In the case of a matter which is subject to Section 3.5 which results in
a Stalemate,  the arbitrator nominated by each Partner shall not be an attorney.
If a Partner  refuses  to name an  arbitrator,  application  will be made to the
Chief Judge of the United  States  District  Court for the Northern  District of
Oklahoma requesting that the

                                       45

<PAGE>



Chief  Judge  appoint an  arbitrator.  If the Chief  Judge  declines  to name an
arbitrator,  application  will be  made to the  AAA.  The two  arbitrators  thus
selected will confer  within ten (10) working days of their final  selection and
agree upon a third  arbitrator.  If the two arbitrators are unable to agree on a
third  arbitrator  within sixty (60) working  days of their first  contact,  the
nomination  of the  third  arbitrator  will  follow  the same  procedure  as the
nomination of a party  arbitrator for a party refusing to make a selection.  AAA
Rules regarding the selection,  qualification, and challenge or arbitrator shall
only apply to the second or third  arbitrators if those arbitrators are selected
by the  AAA.  No  member  of  the  Arbitration  Panel  may  be  involved  in the
controversy, be or have been an officer, director,  representative,  employee or
agent of or for either party.  The third arbitrator shall act as Chairman of the
Arbitration Panel.

         (c) The  costs and fees of the  arbitrators  selected  by the  Partners
shall be borne by the  Partners  selecting  such  arbitrator,  unless  otherwise
awarded by the Arbitration  Panel. The costs and fees  attributable to the third
arbitrator shall be shared equally by the Partners,  unless otherwise awarded by
the Arbitration Panel.

         (d) The Arbitration  Panel may engage  engineers,  accountants or other
consultants  that the Arbitration  Panel deems necessary to render a decision in
the  Arbitration  Proceeding.  All fees of any such  consultants  shall be borne
equally by the Partners, unless otherwise awarded by the Arbitration Panel.

         (e) The arbitration will be governed by the Federal  Arbitration Act, 9
U.S.C.  ss.ss. et seq., and the Oklahoma Uniform Arbitration Act, 15 Okla. Stat.
ss.ss. 801 et seq. The arbitrators will establish a schedule that will result in
a final  arbitration  award to be  rendered  in written  form not later than one
hundred eighty (180) days following the appointment of the third arbitrator. The
place of the arbitration shall be Tulsa, Oklahoma.

         (f) The  Partners  agree  that  pre-arbitration  hearing  discovery  is
necessary.  Within twenty (20) working days after the  appointment  of the third
arbitrator,  the Partners  agree to exchange lists of the witnesses and exhibits
each then plans to call and use in the Arbitration  Hearing.  Within twenty (20)
working days after the exchange of witness and exhibit  lists,  each Partner may
request additional discovery,  if any is necessary,  from the other Partner. The
Partners agree to respond to any such additional  request for documents from the
other Partner  within thirty (30) days after  receiving  such request,  and each
agrees to  attempt  in good  faith to  schedule  the  depositions  of  witnesses
requested by the other side by agreement. If the Partners are unable to agree on
any aspect of discovery  requested,  such discovery  issue shall be presented to
and resolved by the Arbitration Panel.

         (g)  Any  dispute   relating  to  or  arising  under  this  arbitration
provision,  including  interpretation  thereof,  shall  be  solely  and  finally
resolved by submission to the Arbitration Panel.

         (h) A written  decision by two (2) of the arbitrators will be final and
binding on the Partners.  An arbitration  award will be in writing and signed by
the arbitrators. An arbitration award

                                       46

<PAGE>



entered  herein can be confirmed by either of the Partners in the United  States
District Courts for the Northern or Western Districts of Oklahoma or the Western
District of Arkansas or any state  district  court for the States of Oklahoma or
Arkansas,  and a judgment  may be entered on the  arbitration  award by the same
court.

         (i) Punitive  damages may not be awarded by the Arbitration  Panel. The
Arbitration Panel shall have the power to award recovery to the prevailing party
of all  or  part  of  its  costs,  expenses  and  attorneys'  fees  incurred  in
conjunction with such Arbitration Proceeding.

         (j) The Partners, their Affiliates, employees, contractors,  attorneys,
and auditors  shall keep the  substance  of these final and binding  arbitration
proceedings confidential to the extent the same is permissible,  consistent with
the  responsibilities of the attorneys under the pertinent Codes of Professional
Responsibility  or  obligations  which  may  reasonably  require  disclosure  to
financial institutions, consultants for evaluation purposes or as may be ordered
by the federal or state government or a court of competent  jurisdiction.  Under
no circumstances  shall any documents  memorializing the substance of any aspect
of these  proceedings  be disclosed or released to the  newspaper or other media
absent  the  mutual  agreement  of the  Partners.  The  Partners  will  use  all
reasonable  efforts to obtain  protective  orders before disclosing any terms of
these  proceedings  to any federal or state  government  or a court of competent
jurisdiction.

         (k) Except for the internal  costs of each party,  all costs,  fees and

                                    Exhibit A

                                 DESCRIPTION OF
             INTERCONNECTION, INTEGRATION AND EXPANSION OF PIPELINE
                          FACILITIES OF NOARK AND OZARK


         Following are capital  improvements  proposed to combine and expand the
existing Ozark and NOARK systems.

Pipeline

         Tie NOARK and Ozark systems together at their farthest west crossing in
Sebastian County,  Arkansas. This tie-in would include approximately 600 feet of
10-inch piping, relocation of existing pigging facilities to the terminus of the
10-inch addition and conversion of the existing 10 inch Ft. Chaffee suction line
to interconnect  discharge service. This will give the existing NOARK compressor
station in  Franklin  County,  Arkansas a common  suction to both  systems.  The
improvements  for  this  connection  will  also  include  appropriate  crossover
valving, bypass valving, crossover risers and interconnection site as necessary.

         Construct two, 20-inch diameter pipeline  segments,  approximately 4.75
miles each, to integrate the Ozark and NOARK systems  through the existing NOARK
compression. One 20-inch pipeline, which will serve as a suction connection from
Ozark to the NOARK station, will span from the area of milepost 123 on the Ozark
system to the suction of the existing NOARK compression in Franklin County.  The
other  20-inch  pipeline  will  follow  the same  corridor  and will  serve as a
discharge  pipeline back to the existing  Ozark system near milepost 123.  These
improvements  will also include the appropriate  block valve,  crossover piping,
crossover risers and interconnect site as necessary.

Compression

Upgrade the existing  Ozark  Lequire  compressor  station to handle more volume.
Installation of between 7,000 and 11,000 horsepower of additional compression at
the Lequire  station,  dependent  on final  design and  utilization  of existing
turbine  compression.  Installation  to include  related  station  yard  piping,
valving, electrical switchgear, and electric facilities as required.

Upgrade  the  existing   NOARK   compressor   station  to  handle  more  volume.
Installation of approximately 13,000 horsepower of additional compression at the
NOARK station.  Station manifold and yard piping will be adapted as necessary to
accept the new suction and discharge lines to the Ozark system including 20 inch
pig launcher and receiver  facilities.  Appropriate valving and piping will also
be added to provide flexibility to discharge into either or both systems.



                                       A-1

<PAGE>



Measurement

Upgrade receipt metering stations to provide  additional design receipt capacity
from the existing  Enogex and Transok  metering  points into the Ozark  pipeline
system.  Facilities to include additional valving,  meter tubes and telemetry to
meet AGA standards.

Scada

Upgrade  existing  Ozark  and/or NOARK Scada  system(s) to provide  interconnect
communication  between the Ozark and NOARK pipeline systems consistent with FERC
requirements and sound operating practices.

                                       TO
                         AMENDED AND RESTATED AGREEMENT
                            OF LIMITED PARTNERSHIP OF
                   NOARK PIPELINE SYSTEM, LIMITED PARTNERSHIP
                             DATED JANUARY 12, 1998


         These  Accounting  Procedures  are a part of, and are to be interpreted

                               GENERAL PROVISIONS

1.       Statements and Billings

         Each Partner shall render all bills and  statements to the  Partnership
on or before the last day of each month for the costs, expenses and expenditures
for the preceding  months.  Such bills will be accompanied by a statement of all
charges and credits to the Partnership,  including discounts, if any, summarized
by appropriate classifications indicative of the nature thereof.

2.       Payment by Partnership

         The  Partnership  shall pay all bills  within  fifteen  (15) days after
receipt thereof.  If payment is not made or cash funds are not made available to

interest until paid at one (1) percentage point over the prime rate from time to
time charged by Citibank,  N.A., New York,  N.Y. to  responsible  commercial and
industrial borrowers, not in excess of the maximum lawful rate.

3.       Adjustments

         Payment of any bill shall not prejudice the right of the Partnership to
protest or question the correctness  thereof;  provided,  however, all bills and
statements   rendered  to  the  Partnership   during  any  calendar  year  shall
conclusively  be presumed to be true and correct after  twenty-four  (24) months
following  the  end of  such  calendar  year,  unless  prior  to the end of said
twenty-four (24) month period the Partnership  takes written  exception  thereto
and makes claim for  adjustment.  The  provisions  of this  paragraph  shall not
prevent  adjustments  resulting  from a physical  inventory of the assets of the
Partnership or mathematical errors.

no circumstances will there be any double collection of costs.

                                      III.
                                BASIS OF CHARGES

l.       Purchases

         Material  purchased and services procured shall be charged at the price

         2. Other  material shall be priced at the current  replacement  cost of
the same kind of material,  effective at the date of movement by the Partner and
f.o.b.  the supply  store or railway  receiving  point  nearest the System where
material of the same kind is available.

         3. The Partnership shall be credited with cash discounts  applicable to
prices provided for in this Paragraph 2 of Part III.

         B.       Used Material

         1. Used  material in sound and  serviceable  condition and suitable for
reuse shall be priced at seventy-five  percent (75%) of the current price of new
material as determined in Paragraph 2A above.

         2. Used  material  which cannot be  classified  as being in a sound and
serviceable  condition and which is no longer suitable for its original purpose,
but usable for some other purpose,  shall be priced on the basis comparable with
that of items normally used for such other purpose,

         3.       Premium Prices

         Whenever material is not readily obtainable at the prices  contemplated
by a Partner for a project (which  project has received all necessary  approvals
as provided in this Agreement) because of national emergencies, strikes or other
unusual  causes over which such Partner has no control,  such Partner may charge
for the required  material at the premium price (including the cost of making it
suitable for use and of moving it to the System), provided that further approval
therefor has been obtained from the Management Committee.

         4.       Warranty of Material Furnished

         A Partner  shall not be  required  to warrant  any  material  furnished
beyond,  or in addition to, the warranty or guaranty of the  manufacturer or its
agent.  In the case of  defective  material,  credit  shall not be passed to the
Partnership  until adjustment from such  manufacturer or agent has been received
by the Partner.

         5.       Equipment and Facilities Furnished

         A. A Partner  shall charge for the use of its  vehicles,  equipment and
facilities at rates commensurate with the cost of ownership and operation.  Such
rates shall  include the cost of  operation,  maintenance,  repairs,  insurance,
taxes and  other  necessary  and  usual  expenses  and  depreciation.  Rates for
automotive  equipment shall generally be in line with rates currently prevailing
in the area.  Rates for  laboratory  services  shall not exceed those  currently
prevailing if performed by outside  service  laboratories.  Rates for trucks and
tractors  may include  wages and  expenses of the  operators  of such trucks and
tractors.

                                       B-6

<PAGE>



         B. When requested,  a Partner shall inform the Management  Committee in
advance of the rates it proposes to charge.

         C. Rates shall be revised and adjusted  from time to time when found to
be either insufficient or excessive by the Management Committee.

                  Any other provision of this Article III  notwithstanding,  all
materials furnished from a Partner's warehouse for an amount in excess of $5,000
per item shall be billed on the basis of competitive bids obtained from at least
three (3) suppliers in the System area.

                                       IV.
                              DISPOSAL OF MATERIAL

         A Partner may  purchase,  but shall be under no obligation to purchase,
the interest of the  Partnership in material which has become surplus  material.
The disposition of such surplus material,  if not purchased by a Partner,  shall
be subject to  disposition as directed by the  Management  Committee,  provided,
that,  the Project  Leader shall dispose of normal  accumulations  of junk scrap
material.  The Project  Leader will give notice to the  Management  Committee of
surplus materials for sale. In connection with the disposal of surplus material,
the following provisions shall apply:

1.       Material Purchased by a Partner

         Material  purchased  by a Partner  shall be paid for by such Partner in
the month in which the material is removed by such Partner.

2.       Sales to Outsiders

         Sales of material to outsiders  shall be credited by the Project Leader
to the  Partnership  at the net amount  collected  by the  Project  Leader  from
vendee.  The Project  Leader shall take all  reasonable  and necessary  steps to
collect such proceeds. Any claim by vendee related to such sale shall be charged
back to the Partnership if and when paid.

                                       V.
                        BASIS OF PRICING SURPLUS MATERIAL
                            TRANSFERRED TO A PARTNER

         Material  purchased by a Partner,  unless  otherwise  agreed to between
such Partner and the Management Committee, shall be priced after taking at least
three (3) competitive bids on the following basis:


                                       B-7

<PAGE>



1.       New Price Defined

         New price as used in this Part V shall be the price  determined for new
material in Part III.

2.       New Material

         New Material,  being material  procured for the System but never used -
at one hundred percent (100%) of current new price (plus sales tax, if any).

3.       Used Material

         A.  Used  material  which is in sound  and  serviceable  condition  and
suitable for reuse at seventy-five percent (75%) of current new price or at such
lesser amount as is agreed upon by the parties.

         B. Used  material  which cannot be  classified  as being in a sound and
serviceable  condition and which is no longer suitable for its original purpose,
but  usable for some other  purpose - at a price  comparable  with that of items
normally  used for such other  purpose,  or at such lesser  amounts as is agreed
upon by the parties.

         C. Junk  material,  being  obsolete and scrap  material - at prevailing
prices.

4.       Temporarily Used Material

         When  new  material  has been  used for less  than one (1) year and its
service to the System does not justify the  reduction in price  contemplated  by
Paragraph 3 of this Part V, such  material  shall be priced on a basis that will
leave a net  charge to the  Partner  consistent  with the  value of the  service
rendered.

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 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 1997 presentation. These reclassifications had no
effect on previously reported net income.

Results of Operations
     Net income in 1997 was $18.7  million,  or $.76 per share,  down from $19.2
million,  or $.78 per share,  in 1996. Net income in 1995 was $11.2 million,  or
$.45 per share. During 1997, the benefit of higher gas prices and a utility rate
increase  was  more  than  offset  by  increased  depreciation,   depletion  and
amortization  expense (DD&A) and higher interest costs,  resulting in the slight
drop in earnings. The increase in 1996 earnings, as compared to 1995, was due to
improved  natural gas prices and increased  deliveries  in the gas  distribution
segment that  resulted  from colder  weather and customer  growth.  Revenues and
operating  income for the  Company's  major  business  segments are shown in the
following table.

================================================================================
</TABLE>

Exploration and Production
     The Company's exploration and production revenues increased 15% in 1997 and
37% in 1996.  The  increase in 1997 was due to higher  average gas prices and an
increase in the Company's oil production. The increase in 1996 was primarily the
result of higher average gas prices and increased  sales of gas to the Company's
gas distribution segment.
     Operating  income  of the  exploration  and  production  segment  was $33.3
million in 1997, down 3% from $34.2 million in 1996.  Operating income was $20.1
million in 1995.  During 1997, higher DD&A expense offset the effect of improved
gas pricing and higher oil production.
     Gas production decreased to 33.4 billion cubic feet (Bcf) in 1997 from 34.8
Bcf in 1996.  Gas  production  was 34.5 Bcf in 1995.  A decrease in sales to the
Company's gas  distribution  systems in 1997 was partially offset by an increase
in sales to unaffiliated  purchasers.  The production  increase in 1996 resulted
from increased sales to the Company's gas distribution systems, partially offset
by a reduction in sales to unaffiliated purchasers.

     Gas sales to  unaffiliated  purchasers  were 19.1 Bcf in 1997, up from 18.5
Bcf in 1996 and down  from 20.6 Bcf in 1995.  Gas  production  during  1997 from
producing  properties acquired in late 1996 and from drilling in New Mexico more
than offset normal declines in production  from the Company's other  properties.
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
8.6 Bcf in 1997, 10.1 Bcf in 1996, and 8.5 Bcf in 1995.  Colder weather in early
1996,  along with the resulting  need for  injections to replenish the utility's
storage  facilities,  caused higher demand for gas supply by AWG that year.  The
Company's gas production  provided  approximately  64% of AWG's  requirements in
1997,  62% in 1996,  and 65% in 1995.  Most of the  sales  to AWG's  system  are
pursuant  to a  long-term  contract  entered  into in 1978 which was amended and
restated in 1994 as a result of the Gas Cost  Settlement,  discussed  more fully
below under  "Regulatory  Matters." The sales price under this contract averaged
$3.35 per thousand  cubic feet (Mcf) in 1997,  $3.03 per Mcf in 1996,  and $2.40
per Mcf in 1995. This contract expires July 24, 1998. In March,  1997, AWG filed
a gas supply plan with the  Arkansas  Public  Service  Commission  (APSC)  which
projects  system load growth  patterns  and long range gas supply  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

                                       23

<PAGE>
bidding  process.  Other sales to AWG are made under  long-term  contracts  with
flexible pricing provisions.
     The  Company's   intersegment  sales  to  Associated  Natural  Gas  Company
(Associated),  a  division  of AWG which  operates  the  Company's  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.  Deliveries  to  Associated
decreased in 1997 and increased in 1996 due primarily to  corresponding  changes
in heating weather.  Effective October,  1990, one of the Company's  exploration
and production  subsidiaries 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.
     The overall  average  price  received at the wellhead for the Company's gas
production  was $2.57 per Mcf in 1997,  $2.26 per Mcf in 1996, and $1.72 per Mcf
in 1995.  The  increase  in the  average  price  received  since 1995  primarily
reflects  changes in average  annual spot  market  prices and an increase in the
proportionate  share of the Company's  production sold at spot market prices and
under long-term contracts with market-sensitive pricing.
     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 expects the average
price it  receives  for its total gas  production  to be  generally  higher than
average  spot market  prices due to the prices it receives  under the  contracts
covering its  intersegment  sales which are long-term and 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.
     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 which will  continue to be developed  and  evaluated in the future.
The Company's  exploration  programs have been directed primarily toward natural
gas in recent years.  The Company will continue to concentrate on developing and
acquiring  gas  reserves,  but  will  also  selectively  seek  opportunities  to
participate in projects oriented toward oil production.
     Oil production during 1997 totaled 749,000 barrels, up from 391,000 barrels
in 1996  and  229,000  barrels  in 1995.  The  increase  in 1997 oil  production
resulted from the Company's  acquisition of oil and gas properties owned by L.B.
Simmons Energy, Inc. (Simmons).  The acquisition was effective November 1, 1996,
and added proved reserves of 6 million barrels of oil and 17 Bcf of gas.

Gas Distribution
     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 by 8% in 1997 and by 19% in 1996. The
increase in 1997 resulted from an increase in the average utility rate caused by
higher gas prices and a rate increase  implemented in late 1996. The increase in
1996 was due both to an increase in the  average  utility  rate caused by higher
gas prices and weather which was 6% colder than in 1995.
     Operating income for  Southwestern's  utility systems increased 21% in 1997
and by 31% in 1996.  The increase in 1997 was the result of the full year effect
of a $5.1  million  annual  rate  increase  implemented  in  late  1996  for the
utility's  northwest  Arkansas  system and customer growth of 2% which more than
offset lower deliveries  resulting from warmer weather. The increase in 1996 was
primarily caused by colder weather.

     In 1997, AWG sold 17.4 Bcf to its customers at an average rate of $5.34 per
Mcf, compared to 18.8 Bcf at $4.40 per Mcf in 1996 and 17.1 Bcf at $3.93 per Mcf
in 1995. Additionally, AWG transported 5.0 Bcf in 1997, 4.2 Bcf in 1996, and 4.3
Bcf in 1995 for its end-use customers. Associated sold 10.2 Bcf to its customers
in 1997 at an  average  rate of $5.39 per Mcf,  compared  to 11.1 Bcf in 1996 at
$4.87 per Mcf and 10.3 Bcf at $4.45 per Mcf in 1995. Associated  transported 1.6
Bcf for its end-use customers in 1997, compared to 1.3 Bcf in 1996 and .9 Bcf in
1995.  The decrease in the combined  volumes sold and  transported  in 1997,  as
compared to 1996,  for both AWG and  Associated  resulted  from warmer  weather,
partially  offset  by  increases  in  the  average  number  of  customers.   The
fluctuations  in the average sales rates reflect  changes in the average cost of
gas purchased for delivery to the 

                                       24

<PAGE>
Company's  customers,  which are passed  through to  customers  under  automatic
adjustment clauses,  and a rate increase for AWG that was implemented  December,
1996.
     Total deliveries to industrial  customers of AWG and Associated,  including
transportation  volumes,  were  13.2  Bcf in both  1997 and 1996 and 13.0 Bcf in
1995. AWG also  transported 2.8 Bcf of gas through its gathering  system in 1997
for off-system deliveries, all to the NOARK Pipeline System (NOARK), compared to
3.6 Bcf in 1996 and 9.8 Bcf in 1995.  The decreases in off-system  deliveries in
1997  and  1996  were  due  to  the  on-system  demands  of  the  Company's  gas
distribution systems resulting from the colder than normal weather combined with
normal production declines in the area served by the utility's gathering system.
The average  transportation  rate was approximately  $.16 per Mcf,  exclusive of
fuel, in 1997 and 1996, and $.13 in 1995.
     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.  In  December,  1996,  AWG
received  approval from the APSC for a rate  increase of $5.1 million  annually.
The Company received approvals in December, 1997, from the APSC and the Missouri
Public  Service  Commission  (MPSC) for rate  increases and tariff changes which
will 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 will
review  these  gathering  costs  annually  as  part  of  its  annual  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  plans to appeal  this issue to the  courts  and  intends to bill its
ratepayers gas gathering  costs based on its cost of service until the matter is
resolved.
     If usage of the Company's  gathering  system to obtain system gas supply or
to source gas  delivered  to its  industrial  customers  should  decrease,  then
recovery of these gathering  costs would decrease as well.  Gathering costs have
been recovered in this manner from Missouri  customers since  Associated's  1990
rate case.  Prior to the  current  changes,  Associated's  gathering  costs were
recovered from Arkansas customers through its base rates.
     Tariffs  implemented in Arkansas as a result of both the 1996 and 1997 rate
increases 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
investments in property, plant and equipment.

Energy Services
     Operating  income  for the  energy  services  segment  was $1.3  million on
revenues of $82.8 million in 1997, compared to a loss of $.5 million on revenues
of $30.0 million in 1996, and income of $.1 million on revenues of $31.0 million
in 1995. The Company increased its marketing activities when it formed an energy
services  group in mid-1996 to better  enable the Company to capture  downstream
opportunities  which arise through marketing and  transportation  activity.  The
Company marketed 36.2 Bcf in 1997,  compared to 13.0 Bcf in 1996 and 19.9 Bcf in
1995.  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).
     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. NOARK is a 258-mile long intrastate
gas transmission  system which extends across northern Arkansas,  crossing three
major interstate pipelines and interconnecting  with the Company's  distribution
systems.  NOARK has 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  for NOARK  included in other  income was $4.5 million in 1997,
$3.8  million in 1996,  and $.7 million in 1995.  The 1995 pretax loss  included
$2.9 million of income for the Company's  share of a $6.0 million  settlement of
contract issues with one of NOARK's transporters. Deliveries are currently being
made by NOARK to portions of AWG's  distribution  system, to Associated,  and to
the interstate pipelines with which NOARK  interconnects.  In 1997, NOARK had an
average  daily  throughput  of 39.8  million  cubic feet of gas per day (MMcfd),
compared  to 57.5  MMcfd in  1996,  and 86  MMcfd  in  1995.  NOARK  has a total
transportation  capacity of  approximately  141 MMcfd.  AWG has a transportation
contract  with NOARK for 52.3 MMcfd of firm  capacity.  The contract  expires in
2002 and is  renewable  annually  thereafter  until  terminated  with 180  days'
notice.
     The  APSC  currently   regulates   NOARK  and  has  established  a  maximum
transportation  rate of approximately  $.285 per dekatherm based on its original
construction  cost estimate of  approximately  $73 million.  Due to construction
conditions  and the addition of a compressor  station,  the ultimate cost of the
pipeline exceeded the original  estimate by approximately  $30 million.  NOARK's
operating  performance has also been negatively  impacted by a lack of access to
adequate gas supplies.
     As a result of the  continuing  losses from its  investment  in NOARK,  the
Company  investigated  various options to improve the financial prospects of the
venture,  including an extension

                                       25

<PAGE>
to Oklahoma  which would access  additional  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
million.  The two  pipelines  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.  As further  explained
in Note 12 to 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  NOARK.  As a part of the  transaction  with Enogex,
$50.4 million of NOARK's 9.74% Senior  Secured Notes were prepaid and refinanced
with an interim loan from Enogex.  The  partners  plan to refinance  the interim
loan on a permanent  basis before the end of 1998.  The Company's  interest will
continue  to bear 60% of the debt  service on the  existing  level of NOARK debt
after its  refinancing.  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 eliminate 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.

Regulatory Matters
     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 is to begin in 1998 in accordance with a procedural
schedule established by the APSC.
     During 1994,  the Company  entered into a settlement  with the Staff of the
APSC and the Office of the Attorney  General of the State of Arkansas to resolve
a dispute  concerning the Company's pricing of intersegment  sales (the Gas Cost
Settlement).  The  issues  involved  the  price  of gas sold  under a  long-term
contract  between AWG and one of the Company's gas producing  subsidiaries.  The
Gas Cost  Settlement,  which was effective  July 1, 1994,  increased the volumes
which could be sold by the Company's  exploration and production segment to AWG,
but made the sales  price  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 be sold at the spot market  index plus a premium of $.95 per
Mcf,  while  incremental  sales  volumes  receive a premium of $.50 per Mcf.  As
discussed above in "Exploration and Production,"  this contract expires July 24,
1998.  While the APSC has not yet approved a gas supply plan submitted by AWG to
address  the  expiration  of this  contract,  the Company  anticipates  that the
volumes will continue to be sold to AWG. In 1997,  approximately 8.2 Bcf (net to
the  Company's  interest)  was sold under the  existing  contract,  compared  to
approximately 8.6 Bcf and 7.7 Bcf in 1996 and 1995, respectively.
     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.  Such  exposure has  increased in
recent years as a result of a decline in its gas purchase requirements which has
occurred as some of its large business  customers  converted to a 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.

Operating Costs and Expenses
     The Company's  operating costs and expenses,  exclusive of gas purchases by
the Company's utility and marketing segments,  increased by 16% in both 1997 and
1996.  The  increases in both years were due primarily to increases in operating
and general  expenses,  and  depreciation,  depletion and amortization  expense.
Increased  operating  and general  expenses  primarily  relate to the  Company's
exploration  and  production  segment.  The higher costs in large part represent
increased  operating costs  associated  with the Company's  expansion into areas
outside of Arkansas.  During 1997,  production costs associated with certain oil
properties  acquired in  November,  1996  accounted  for most of the increase in
operating expense.  General and  administrative  expenses have increased in 1997
and 1996 due to  inflationary  increases  in  payroll  and other  costs and from
personnel  additions.  The  increase in DD&A  expense for both 1997 and 1996 was
primarily due to an increase in the amortization  rate per unit of production in
the exploration and production segment.
     The Company follows the full cost method of accounting for the exploration,
development, and acquisition of oil and gas properties. DD&A is calculated using
the units-of-production  method. The Company's annual gas and oil production, as
well as the  amount  of  proved  reserves  owned by the  Company  and the  costs
associated  with adding those reserves,  are all components of the  amortization
calculation.  The DD&A rate in 1997 was $1.06 per Mcfe, up from $.95

                                       26


<PAGE>
per Mcfe in 1996 and $.82 per  Mcfe in  1995.  The  increases  in the  Company's
amortization  rate were caused by increases  in the  Company's  average  finding
costs.  The Company's full cost ceiling is evaluated at the end of each quarter.
Market prices, production rates, levels of reserves, and the evaluation of costs
excluded  from  amortization  all  influence  the  calculation  of the full cost
ceiling.  A decline in oil and gas prices  from  year-end  1997  levels or other
factors, without other mitigating circumstances, could cause a future write-down
of capitalized costs and a noncash charge against future earnings.
     Gas purchased for resale by the Company's  marketing  segment  increased to
$63.1  million in 1997,  compared to $14.1  million in 1996 and $13.7 million in
1995, due to an increase in volumes marketed and higher per unit gas costs.
Increases in purchased gas costs for the Company's gas  distribution  segment in
both 1997 and 1996 were due  primarily  to higher per unit gas costs.  Purchased
gas costs for the gas distribution  segment are influenced  primarily by changes
in  requirements  for gas  sales,  the price and mix of gas  purchased,  and the
timing of recoveries of deferred purchased gas costs.
     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 1997 the impact of inflation intensified in the Company's
exploration  and production  segment as shortages in drilling rigs,  third party
services and qualified labor increased. Increased competition in south Louisiana
also had the  impact  of  increasing  3-D  seismic  and land  costs in the area.
Additionally,  delays  inherent in the  rate-making  process prevent the Company
from  obtaining  immediate  recovery  of  increased  operating  costs of its gas
distribution segment.

Other Costs and Expenses
     Interest costs, net of capitalization, were up 26% in 1997 and 17% in 1996,
both as compared  to prior  years,  due to  increases  in  long-term  debt.  The
increases  in  long-term  debt are  discussed  below in  "Liquidity  and Capital
Resources."  Interest  capitalized  increased  8% in 1997 and 69% in  1996.  The
increase in 1996 was due primarily to higher  capital  expenditures  in 1996 and
1995 in the exploration and production  segment where interest is capitalized on
costs excluded from amortization.
     The changes in other income in 1997 and 1996,  as compared to 1995,  relate
primarily to increases in the Company's  share of operating  losses  incurred by
NOARK as discussed above.
     The Company's  primary  information  processing  systems are currently year
2000  compliant,  or  upgraded  versions  that are year 2000  compliant  will be
implemented  during 1998 at no  additional  cost to the Company.  The Company is
currently in the process of  evaluating  its remaining  information  tech-nology
infrastructure  for year 2000 compliance.  It does not expect the cost to modify
the technology  infrastructure  to obtain year 2000 compliance to be material to
its financial  condition or results of  operations,  nor does it anticipate  any
material   disruption   in  its   operations  as  a  result  of  any  year  2000
noncompliance.

Liquidity and Capital Resources
     The Company continues to depend  principally on internally  generated funds
as its major source of liquidity. However, the Company has sufficient ability to
borrow  additional  funds to meet its  short-term  seasonal  needs for cash,  to
finance a portion of its routine  spending,  if  necessary,  or to finance other
extraordinary  investment  opportunities  which might arise. In 1997,  1996, and
1995, net cash provided from operating  activities totaled $75.4 million,  $67.6
million,  and  $55.9  million,  respectively.  The  primary  components  of cash
generated  from   operations  are  net  income,   depreciation,   depletion  and
amortization,  and the  provision  for  deferred  income  taxes.  Net cash  from
operating  activities  provided 75% of the Company's  capital  requirements  for
routine capital expenditures,  cash dividends, and scheduled debt retirements in
1997, 77% in 1996, and 59% in 1995.

Capital Expenditures
     Capital expenditures totaled $88.8 million in 1997, $124.9 million in 1996,
and $101.6 million in 1995.  The Company's  exploration  and production  segment
expenditures  included acquisitions of oil and gas producing properties totaling
$45.8  million in 1996 and $6.0  million in 1995.  The Company made no producing
property acquisitions in 1997.

     The  Company  generally  intends  to adjust  its level of  routine  capital
expenditures  depending on the expected  level of internally  generated cash and
the level of debt in its capital  structure.  The Company expects that its level
of capital  spending  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.
     Capital spending  planned for 1998 totals $74.2 million,  a decrease of 16%
from actual 1997  spending,  consisting  of $59.2  million for  exploration  and
production,  $12.3 million for gas distribution  system  expenditures,  and $2.7
million for general purposes.

Financing Requirements
     At  year-end  1997,  Southwestern's  total  debt was $299.5  million.  This
compares to year-end 1996 total debt of $278.3 million.
     Two floating rate revolving credit facilities provide the Company access to
$80.0  million  of  variable  rate  long-term  capital.  These  facilities  were
temporarily  expanded  to  $120  million  in  1996 to  provide  additional  debt
financing  to  fund  the  acquisition  of  the  Simmons  properties.  Borrowings
outstanding  under these credit  facilities  totaled $46.4 million at the end of
1997 and $96.5 million at the end of 1996.

                                       27


<PAGE>
     In May, 1997, the Company issued $60.0 million of 7.625%  Medium-Term Notes
due 2027.  The notes may be repaid  prior to  maturity  on May 1,  2009,  at the
noteholder's  option.  In October,  1997,  the Company  issued $40.0  million of
Medium-Term  Notes  due  2017 at a  weighted  average  interest  rate of  7.21%.
Proceeds from the issuance of these notes were used to repay certain  borrowings
under the Company's revolving credit facilities.  All of 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's  public  notes are  rated  BBB+ by  Standard  and  Poor's  and Baa2 by
Moody's.
     As  explained  above  in  "Energy  Services,"  the  Company  has  severally
guaranteed  60% of the principal and interest  payments on  approximately  $78.2
million of debt  payable by NOARK at December  31,  1997.  Of the total,  Senior
Secured Notes with a principal  balance of $50.4 million are now pay-able to the
other  general  partner of NOARK  pursuant to an interim  arrangement  requiring
annual principal payments of $3.2 million,  plus interest on the unpaid balance.
NOARK's remaining debt is pursuant to a $30.0 million unsecured revolving credit
agreement  with a group of banks which  currently  matures  April 26, 1998.  The
partnership  intends  during  1998 to  refinance  the Senior  Secured  Notes and
revolving credit agreement  through a new issue of long-term notes. In 1997, the
Company  advanced  $5.0  million  to  NOARK to fund  its  share of debt  service
payments. The Company expects to advance up to $3.6 million to NOARK during 1998
in connection with its guarantees.
     Under its existing  debt  agreements,  the Company may not issue  long-term
debt in excess  of 65% of its total  capital  and may not  issue  total  debt in
excess of 70% of its total  capital.  To issue  additional  long-term  debt, the
Company must also have, after giving effect to the debt to be issued, a ratio of
earnings  to fixed  charges of at least 1.5 or higher.  At the end of 1997,  the
capital  structure  consisted of 57.2% debt  (excluding  the current  portion of
long-term debt and the Company's several  guarantee of NOARK's  obligations) and
42.8%  equity,  with a ratio of earnings to fixed  charges of 2.1. Over the long
term, the Company expects to lower the debt portion of its capital  structure by
limiting its routine capital spending.

Working Capital
     The Company  maintains access to funds which may be needed to meet seasonal
requirements  through the revolving lines of credit explained above. The Company
had net  working  capital  of $39.0  million  at the end of 1997,  up from $31.1
million at the end of 1996.  Current assets increased by 21% to $88.0 million in
1997, while current liabilities  increased 17% to $49.0 million. The increase in
current  assets at December 31, 1997, was due primarily to increases in accounts
receivable,  gas storage inventory and under-recovered  purchased gas costs. The
increase in accounts  receivable  was due  primarily  to higher  weather-related
sales at year-end 1997 and increased gas volumes marketed by the energy services
segment.  The increase in gas storage inventory at December 31, 1997, was due to
both higher volumes stored and a higher  weighted  average cost. The increase in
under-recovered purchased gas costs relates to the increased cost of natural gas
purchased during 1997. These costs will be recovered from the Company's  utility
customers in subsequent months through automatic cost of gas adjustment  clauses
included  in  the  utility's  filed  rate  tariffs.   The  increase  in  current
liabilities  resulted  primarily from an increase in accounts payable due to the

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  generally  accepted  accounting   principles   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  and an ongoing  program of internal  audits 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 auditors, Arthur Andersen LLP. In accordance with generally accepted
auditing standards, 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 preformed.
    The Audit  Committee of the Board of Directors,  composed  solely of outside
directors, meets with management,  internal auditors, 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, 1997 and
1996, and the related consolidated  statements of income, retained earnings, and
cash flows for each of the three years in the period  ended  December  31, 1997.
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  generally  accepted  auditing
standards.  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,  1997 and 1996,  and the  results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1997, in conformity with generally accepted accounting principles.

Notes to Financial Statements
Southwestern Energy Company and Subsidiaries
December 31, 1997, 1996 and 1995

(1) Summary of Significant Accounting Policies

Nature of Operations and Consolidation
     Southwestern Energy Company  (Southwestern or the Company) is a diversified
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.
Approximately 65% of the Company's  business is derived from the exploration and
production  segment based on operating  income.  Southwestern's  exploration and
production activities are concentrated in Arkansas, Oklahoma, Texas, New Mexico,
Louisiana,  and the Gulf Coast (primarily onshore). The gas distribution segment
operates in northern Arkansas and parts of Missouri,  and obtains  approximately
60% 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.
     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,
Arkansas  Western  Pipeline  Company,  and A.W. Realty 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 1997 presentation.
     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  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.

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 cost 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 December 31, 1997,  1996,  and 1995, the Company's cost of oil and
gas properties did not exceed such ceiling amounts.
     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 2.2% to 5.6%. 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 40 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 costs 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 gas distribution customers
represent a diversified base of residential,  commercial,  and industrial users.
Approximately  108,000 of these  customers are served in northwest  Arkansas and
approximately 69,000 are served in northeast Arkansas and Missouri.
     The Company records gas  distribution  revenues on an accrual basis, as gas
volumes are used, to provide a proper matching of revenues with expenses.

                                       33


<PAGE>


     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.  Effective December,  1996, for the Company's northwest Arkansas system,
and effective December,  1997, for the northeast Arkansas system, 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.

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,
1997 and 1996 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 has limited involvement with derivative  financial  instruments
and does not use them for  trading  purposes.  They are used to  manage  defined
commodity price risks. The Company uses commodity swap agreements and options to
hedge  sales of natural  gas and crude  oil.  Gains and  losses  resulting  from
hedging  activities are recognized when the related  physical  transactions  are
recognized.  Gains or losses from commodity swap  agreements and options that do
not qualify for accounting treatment as hedges are recognized currently as other
income  or  expense.  See Note 8 for a  discussion  of the  Company's  commodity
hedging activity.

Earnings Per Share and Shareholders' Equity
     The Company has adopted Financial  Accounting Standards Board Statement No.
128,  "Earnings  Per Share" (SFAS No. 128).  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 impact of the  adoption  of SFAS No. 128 had no effect on reported
earnings per share for 1996 and 1995.
     During 1997 the Company issued 117,740 treasury shares under a compensatory
plan and for stock awards and returned to treasury 3,059 shares canceled from an
earlier issue under the compensatory  plan. The net effect of these transactions
was a $1.2 million decrease in treasury stock.

(2) Long-Term Debt

     Long-term debt as of December 31, 1997 and 1996 consisted of the following:

     The Company has several  prepayment  options  under the terms of certain of
its Senior  Notes.  Prepayments  made  without  premium  are  subject to certain
limitations.  Other prepayment  options involve the payment of premiums based in
some instances on market interest rates at the time of prepayment.
     Two variable  rate credit  facilities  provide the Company  access to $80.0
million of long-term revolving credit. Borrowings outstanding under these credit
facilities  totaled  $46.4  million  at  December  31,  1997,  all of which  was
classified as long-term  debt.  Each  facility  allows the Company four interest
rate  options-the  floating  prime rate, a fixed rate tied to either  short-term
certificate  of  deposit  or  Eurodollar  rates,  or a fixed  rate  based on the
lenders' cost of funds.  The revolving  credit  facilities  expire in 2000.  The
Company intends to renew or replace the facilities prior to expiration.

(4) Pension Plan and Other Postretirement Benefits

     Substantially  all employees are covered by the Company's  defined  benefit
pension plan.  Benefits are based on years of benefit service and the employee's
"average   compensation,"  as  defined.  The  Company's  funding  policy  is  to
contribute  amounts  which are  actuarially  determined to provide the plan with
sufficient assets to meet future benefit payment  requirements and which are tax
deductible.
     Plan  assumptions for 1997 and 1996 included an expected  long-term rate of
return on plan assets of 9%, a weighted  average  discount  rate of 7.5% for the
net  pension  cost  computation,  and a  salary  progression  rate  of  5%.  The
reconciliation  of prepaid pension cost at December 31, 1997 utilizes a discount
rate of 7.5% for future settlements.

==================================================================================================
</TABLE>

     In determining the APBO, an assumed  weighted average discount rate of 7.5%
was used for 1997 and 1996.  An  increase  of 10% in the cost of covered  health
care benefits was assumed for 1998. This rate is assumed to decrease  ratably to
6% over 8 years  and  remain  at that  level  thereafter.  The  effect  of a one
percentage  point  increase in the assumed  health care cost trend rate for each
future year would  increase the total APBO at year-end  1997 by $368,000 and the
1997 net postretirement benefit cost by $39,000.

</TABLE>


     Capitalized  interest  is  included  as  part  of the  cost  of oil and gas
properties. The Company capitalized $4.5 million, $4.1 million, and $2.5 million
during 1997,  1996,  and 1995,  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 $6.0 million,  $5.9 million,  and $4.4 million  during 1997,  1996, and
1995,  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.
     The following table shows the  capitalized  costs of gas and oil properties
and the related accumulated depreciation, depletion and amortization at December
31, 1997 and 1996:

</TABLE>
     The  table  below  sets  forth the  composition  of net  unevaluated  costs
excluded from  amortization as of December 31, 1997.  Included in these costs is
$5.1 million  representing  leasehold and seismic costs related to the remaining
unevaluated portion of acreage located on the Fort Chaffee military reservation.
These costs are expected to be evaluated  and subjected to  amortization  within
the next several years as this acreage is further  explored and developed.  Also
included in these  costs is $37.2  million  related to 3-D  seismic  projects in
south  Louisiana.  These  costs  and  subsequent  costs to be  incurred  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

     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
1997, 1996, and 1995:

(7) Investment in Unconsolidated Partnership

     At December 31, 1997, the Company held a 48% general  partnership  interest
in NOARK.  NOARK is a 258-mile long  intrastate  gas  transmission  system which
extends across northern Arkansas. In January,  1998, the Company entered into an
agreement with Enogex Inc.  (Enogex) which will result in the expansion of NOARK
and  provide  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 is a 437-mile  interstate  pipeline system
which begins in eastern Oklahoma and terminates in eastern Arkansas.  Enogex has
entered  into a  separate  agreement  to  acquire  the  Ozark  system  and  will
contribute  it to the NOARK  partnership.  Enogex  has also  acquired  the NOARK
partnership  interests not owned by  Southwestern.  The acquisition of Ozark and
its  integration  with  NOARK is  subject  to  approval  by the  Federal  Energy
Regulatory Commission (FERC). Management expects to obtain approval from FERC in
1998 at which time NOARK will be  converted  to an  interstate  pipeline  and be
operated in combination  with Ozark.  Enogex will fully fund the  acquisition of
Ozark and the expansion and  integration  with NOARK.  After the  integration is
complete,  the  Company  will  own a 25%  interest  in the  partnership  and the
expanded  project and Enogex  will own a 75%  interest.  The parties  expect the
integrated system to be operational by late 1998.
     The Company's investment in NOARK totaled $7.0 million at December 31, 1997
and $6.5  million at  December  31,  1996.  The  Company's  investment  in NOARK
includes  advances of $5.0 million  made during  1997,  $1.3 million made during
1996, and $5.0 million made during 1995,  primarily to provide  certain  minimum
cash balances to service NOARK's long-term debt.
     In  connection  with the Enogex  transaction,  the  Company  and a previous
general  partner  converted  certain  of their  loans to the  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.  See Note 12 for further  discussion  of
NOARK's funding requirements and the Company's investment in NOARK.
     NOARK's  financial  position  at December  31, 1997 and 1996 is  summarized
below,  including an unaudited pro forma balance sheet that presents the effects
of the reorganization of the partnership (excluding the pending contribution and
integration  of the  Ozark  system)  as if such  transactions  had  occurred  at
December 31, 1997:

     The Company's  share of NOARK's  pretax loss,  before the effect of accrued
interest expense on general partner loans, was $4.5 million,  $3.8 million,  and
$.7 million for 1997,  1996,  and 1995,  respectively.  The Company  records its
share of NOARK's  pretax loss in other  income  (expense) on the  statements  of
income.  The 1995 pretax loss  included $2.9 million of income for the Company's
share of a $6.0  million  settlement  of  contract  issues  with one of  NOARK's
transporters.

(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 and Customer  Deposits-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.

=============================================================================================================================
</TABLE>

     Anticipated  regulatory treatment of the excess of fair value over carrying
value  of the  portion  of the  Company's  long-term  debt  attributable  to its
regulatory activities,  if such debt were settled at amounts approximating those
above,  would dictate that these amounts be used to increase the Company's rates
over a prescribed  amortization  period.  Accordingly,  any settlement would not
result in a material  impact on the Company's  financial  position or results of
operations.

Price Risk Management
     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 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),  and (2) transactions in which parties agree
to pay a price based on two different indices (referred to as basis swaps).
     At December 31, 1997, the Company had  outstanding  natural gas price swaps
on total  notional  volumes of 2.2 Bcf. Of the total,  the Company  will receive
fixed prices ranging from $2.49 to $3.27 per MMBtu on 2.0 Bcf.  Under  contracts
covering  the  remaining  .2 Bcf,  the  Company  will make  average  fixed price
payments  of $2.42 per  MMBtu and  receive  variable  prices  based on the NYMEX
futures market. The Company held outstanding basis swaps on a notional volume of
1.9 Bcf. At December 31,  1996,  the Company had  outstanding  natural gas price
swaps on total notional  volumes of 12.1 Bcf. Of the total, the Company received
fixed prices ranging from $2.11 to $2.82 per MMBtu on 11.5 Bcf. Under  contracts
covering the remaining .6 Bcf, the Company made average fixed price  payments of
$3.21 per MMBtu and received  variable prices based on the NYMEX futures market.
At December 31, 1996,  the Company held  outstanding  basis swaps on a no-tional
volume of 5.5 Bcf. The Company also had  outstanding  a price swap on a notional
volume of 450,000  barrels of crude oil for calendar  year 1997 at a fixed price
of $20.75 per barrel. During 1997, the Company recognized losses from price risk
management  activities  of $2.7  million,  which  were  offset by  corresponding
revenue  receipts  from  physical  transactions.  In 1996 and 1995,  the Company
recognized  price  risk  management  losses  of $3.4  million  and $.6  million,
respectively.
     The Company  uses  options to fix a floor,  a ceiling,  or both a floor and
ceiling (a "collar") for prices on its production volumes. At December 31, 1997,
the Company had a crude oil price floor of $18.00 per barrel (based on the NYMEX
futures  market)  on  total  notional  volumes  of  1,450,000  barrels  covering
production  during  calendar  years 1998 through 2001. At December 31, 1996, the
Company had a  fixed-priced  collar  agreement for a notional  volume of 5.6 Bcf
covering the period April through October, 1997, which provided a floor price of
$2.00 per MMBtu and a ceiling price of $2.80 per MMBtu.
     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 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  1993 Stock  Incentive  Plan (1993 Plan)
provides for the  compensation  of officers and key employees of the Company and
its  subsidiaries.  The 1993 Plan  provides  for  grants of  options,  shares of
restricted  stock,  and  stock  bonuses  that  in the  aggregate  do not  exceed
1,275,000  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 do not exceed  1,275,000  shares,  and the grant of limited and tandem
SARs (all terms as defined in the 1993 Plan).  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 plan.
     The  Southwestern  Energy  Company  1993 Stock  Incentive  Plan for Outside
Directors  provides for annual stock option grants of 12,000 shares (with 12,000
limited SARs) to each  non-employee  director.  Options may be awarded under the
plan on no more than 240,000 shares.

     All options are issued at fair market value at the date of grant and expire
ten years from the date of grant.  The options  outstanding at December 31, 1997
had a range of  exercise  prices  from $5.58 to $17.50  and a  weighted  average
remaining contractual life of 7.2 years. Options generally vest to employees and
directors over a three to four year period from the date of grant.  Of the total
options  outstanding,  510,000  performance  accelerated options were granted in
1994 at an option price of $14 5/8.  These options vest over a four-year  period
beginning  six years  from the date of grant or  earlier  if  certain  corporate
performance criteria are achieved.
     The Company has granted  114,686  shares of  restricted  stock to employees
through 1997. Of this total, 75,007 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.
     The  Company  adopted  the  disclosure-only   provisions  of  Statement  of
Financial   Accounting   Standards   No.  123,   "Accounting   for   Stock-Based
Compensation" (SFAS No. 123) in 1996. 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 and earnings per share would have been reduced to
the pro forma amounts indicated below:

     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:  dividend  yield of 1.7% to 2.0%;  expected  volatility of 26.2% to
26.8%; risk-free interest rate of 5.7% to 6.8%; and expected lives of 6 years.

(10) Common Stock Purchase Rights

     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 $25.00,  subject to  adjustment.  These
rights will become  exercisable  in the event that a person or group acquires or
commences a tender offer for 20% 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 20% of the common stock (10% or
more if the Board determines such acquiror is adverse), rightholders (other than
the 20% 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.
     The rights may be  redeemed  by the Board for $.003 per right  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 1999.

(12) Contingencies and Commitments

     The  Company  and  the  other  general  partner  of  NOARK  have  severally
guaranteed the principal and interest payments on approximately $78.2 million of
debt  incurred  in  connection  with  the  construction  of the  existing  NOARK
pipeline.  The  Company's  share of the several  guarantee  is 60%. Of the total
debt,  Senior  Secured  Notes with a fixed  interest rate of 9.74% and principal
balance of $50.4 million were  outstanding  at December 31, 1997,  pursuant to a
long-term  arrangement  requiring  annual  principal  payments  of $3.2  million
together with interest on the unpaid balance.  The remaining debt is pursuant to
a $30.0 million unsecured revolving credit agreement with a group of banks which
currently  matures April 26, 1998. In connection  with the  partnership  changes
discussed  further in Note 7, NOARK also prepaid its 9.74% Senior  Secured Notes
in January, 1998. The notes were refinanced with Senior Secured Notes payable to
the other general  partner of NOARK.  The  partnership  intends to refinance its
Senior  Secured  Notes and  revolving  credit  agreement  through a new issue of
long-term  debt  during  1998.  Additionally,  the  Company's  gas  distribution
subsidiary  has a  transportation  contract with NOARK for firm capacity of 52.3
MMcfd.  The contract expires in 2002, and is renewable  year-to-year  thereafter
until terminated by 180 days' notice.
     Under the several  guarantee,  the Company is required to fund its share of
NOARK's debt service which is not funded by either operations of the pipeline or
by the  available  line of credit.  As a result of the expected  integration  of
NOARK 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.

     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 class  action  suit was filed  against the
Company in May, 1996 on behalf of royalty owners alleging  improprieties  in the
disbursements  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 is subject to laws and  regulations  relating to the protection
of the environment.  The Company's policy is to accrue environmental and cleanup
related  costs of a noncapital  nature when it is both probable that a liability
has been  incurred and when the amount can be reasonably  estimated.  Management
believes any future  remediation or other compliance related costs will not have
a material effect on the financial  condition 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.

Southwestern Energy Company and Subsidiaries
APPENDIX to 1997 ANNUAL REPORT TO SHAREHOLDERS

Description of Exploration & Production Operating Areas:

Southwestern  conducts its exploration and production  efforts primarily in four
areas;  the Arkoma  Basin, the Anadarko  Basin, the Gulf Coast,  and the Permian
Basin.  The Arkoma Basin is located in the central  section of western  Arkansas
and the  central  section of eastern  Oklahoma.  Southwestern's  activities  are
concentrated  in the  historically  productive  Arkansas  section  of the Arkoma
Basin.  The  Anadarko  Basin  covers  most of the western  part of Oklahoma  and
extends to the northwest into the northern  panhandle of Texas and the panhandle
area of Oklahoma.  The Permian  Basin is located in west Texas and the southeast
corner of New Mexico.  Southwestern's Gulf Coast operations include both onshore
and offshore activity along both the Texas and Louisiana coasts.

Description of Gas Distribution Operating Areas:

Arkansas  Western Gas  Company's  (AWG)  northwest  Arkansas gas utility  system
gathers its gas supply from the Arkoma Basin where it also provides distribution
service  to  communities  in  that  area,  including  the  towns  of  Ozark  and
Clarksville.  AWG's  transmission and distribution lines extend north and supply
communities  in the  northwest  part  of  the  state,  including  the  towns  of
Fayetteville,  Springdale,  and Rogers.  AWG's service area also extends east to
the  Harrison and Mountain  Home areas.  This eastern  section of the AWG system
receives  a  portion  of its gas  supply  from a  lateral  line off of the NOARK
Pipeline  System (NOARK) as discussed  below.  Through its division,  Associated
Natural Gas Company  (Associated),  AWG provides  distribution of natural gas to
communities  in  northeast  Arkansas and parts of  Missouri.  Major  communities
served in northeast  Arkansas include  Blytheville,  Piggott,  and Osceola.  The
Associated  distribution  system also serves the  "bootheel"  area in  southeast
Missouri,  including the communities of Sikeston, New Madrid, and Caruthersville
and extends north to the Jackson area. In addition,  Associated provides service
to Butler,  Missouri, near the state's western border and Kirksville,  Missouri,
near the state's northern border through connections off of interstate pipelines
in those areas.

Description of NOARK Pipeline System Operating Area:

Southwestern Energy Pipeline Company owns a  general partnership  interest
in NOARK, a 258-mile intrastate pipeline that ties the Company's gathering and
transmission  pipeline systems in northwest Arkansas to its distribution systems
in northeast Arkansas and southeast Missouri.  NOARK starts near Forth Smith, at
the Fort Chaffee military reservation, and extends east through the Arkoma Basin
and across northern Arkansas. A lateral from NOARK extends north and connects to
AWG's  distribution  line  in  the  Mountain  Home  area.  NOARK  crosses  three
interstate  pipelines in northeast Arkansas and ends at an interconnection  with
Arkansas  Western  Pipeline   Company's  8-mile   interstate   pipeline  at  the
Arkansas/Missouri   border.   This  pipeline   transports   gas  from  NOARK  to
Associated's distribution system.
