                           INCENTIVE COMPENSATION PLAN

                  (Amended and Restated as of January 1, 1999)



         The  name  of  this  plan  shall  be the  Southwestern  Energy  Company
Incentive  Compensation Plan ("Plan").  The Plan Sponsor is Southwestern  Energy
Company (the  "Company").  The Plan is effective for fiscal years of the Company
commencing on or after January 1, 1993 and is hereby  amended and restated as of
January 1, 1999. The Plan Year shall be each successive year beginning January 1
and ending December 31.

A.   PURPOSE
         The  purpose  of this  Plan is to  attract,  retain  and  motivate  key
employees  by providing  cash and stock  incentive  compensation  to certain key
employees  of the  Company  and its  Subsidiaries  (as listed  below) who have a
significant  impact on earnings,  growth and shareholder value by rewarding both
organizational and individual  performance.  The participating  entities include
Southwestern  Energy  Company   ("Corporate"),   Arkansas  Western  Gas  Company
("Utility"),  Southwestern  Energy Production Company and SEECO, Inc. (together,
"E & P"), and Southwestern Energy Services Company ("Marketing").

B.   ADMINISTRATION
         The  Compensation  Committee  ("Committee")  of the Board  of Directors
("Board")  of the  Company  shall  have full power and  authority  to review and
approve the  designation of  Participants,  to approve  annually the performance
measures and payout thresholds,  and to promulgate such rules and regulations as
it deems necessary for the proper  administration  of the

                                      -1-


Plan, to interpret the provisions and supervise the  administration of the Plan,
to certify prior to the payment of any award under the Plan that the appropriate
performance  measures have been achieved giving rise to such awards, and to take
all  action  in  connection  therewith  or in  relation  to the Plan as it deems
necessary or advisable. When authorizing action or taking action with respect to
this Plan,  the  Committee  and/or the Board  shall act  without the vote of any
directors  who shall  fail to meet the  definition  of an  Outside  Director  as
defined in Internal Revenue Code section 162(m) and the regulations thereunder.

C.   PARTICIPATION
         1.   Eligibility--Executives
         Only  active  employees  of the  Company  or its  subsidiaries  who are
employed in a key management  capacity may be designated as  Participants  under
the Plan.

         2.  Designation and Removal of Participants
         Participation  in the  Plan shall be  determined on an annual basis for
each  calendar  year as early as  practicable  in each year.  No person shall be
entitled  to any  award  under  this  Plan for any year  unless  he or she is so
designated as a Participant for that year. The CEO shall make recommendations to
the Committee for the executive Participants in the Plan and their corresponding
Level of  Participation.  The Committee shall have approval  authority as to the
list of executive  Participants and their  corresponding level of participation.
The CEO will establish  annually the employees who will  participate in Level VI
and below bonus tiers.  The Committee may add to or delete  individuals from the
list of  designated  Participants  from  time to time,  at its sole  discretion,
during the year or for  subsequent  years.  Exhibit 1 identifies  those selected
Participants for the Plan Year, their  corresponding  Level of Participation and
their  Performance

                                      -2-


Unit.  A Performance Unit is the Company, Subsidiary or business unit upon whose
Performance Measures the Participant's awards will be determined.

         3.   Notice of Participation
         As soon as  reasonably  practicable,  each person  who is selected as a
Participant  in the Plan for a year will be  notified of his  selection  and his
Level of Participation and the criteria for awards.

         4.   Partial Payments:  New Hires
         If an individual  becomes a new  Participant  during the Plan Year, the
incentive  compensation  award will be earned on the basis of one-twelfth of the
annual incentive  compensation for each full month of employment in the calendar
year of initial employment or promotion. Any exceptions shall be approved by the
Compensation Committee.

D.   THRESHOLDS; PERFORMANCE CRITERIA
         1.   Organizational Performance
         In connection with the  designation of Participants  for each year, the
Committee   shall   establish  each  Plan  Year  minimum,   target  and  maximum
organization  performance  threshold levels  ("Threshold  Levels") for such Plan
Year  based  on  Company  and  Subsidiary   performance  measures  ("Performance
Measures").  The  Committee  may  at  its  discretion  make  adjustments  to the
performance threshold levels or to the actual Performance Measures to remove the
effect of extraordinary items or changes in accounting methods.

         The  Performance  Measures  to  be  used  for  each   Performance  Unit
(Corporate,  Utility,  E&P, and  Marketing)  will be recommended by the CEO, but
shall be set by the Committee.  The

                                      -3-


Weighting  Factors and performance  Threshold Levels are designated on Exhibit 3
and each Performance Measure is defined on Exhibit 3a. The Performance  Measures
and  related  definitions  may be  revised  annually  if deemed  necessary  upon
approval by the Committee.

         Achievement of the  minimum,  target or maximum  Threshold Levels shall
determine the bonus percentages ("Bonus  Percentages") to be used in calculating
bonus  amounts as set forth  herein.  The Bonus  Percentages  applicable to each
Threshold  Level  may be  established  by the  Committee  from  time  to time as
outlined in Exhibit 2. For each  Company  Performance  Measure,  a bonus  amount
shall be  calculated  for the year equal to the Bonus  Percentage  of Salary (as
defined  below)  for each  Participant,  adjusted  by a  percentage  ("Weighting
Factor")  applicable to each Company  Performance  Measure as established by the
Committee  from time to time for each year.  The  Weighting  Factors shall be as
outlined  in Exhibit 3, but may be changed by the  Committee  from year to year,
and additional Company Performance  Measures may be established,  so long as the
sum of the  Weighting  Factors is always  equal to 100  percent.  The sum of the
individual  bonus amounts so established  for each Company  Performance  Measure
shall  be equal to the  Organizational  Performance  Amount.  The  formulas  for
calculating the organizational performance awards are contained on Exhibit 4.

         2.   Individual Performance Award Amount
         The Plan  allows for  discretionary  awards to be made to  Participants
upon  the  recommendation  of the  Company's  Chief  Executive  Officer  and the
approval  of the  Committee.  These  awards  will be  based  upon an  individual
Participant's  performance against individually  established goals or an overall
assessment of a Participant's  contribution in areas that cannot be quantifiably
measured.  The  amount  so  determined  shall be the  Participant's  "Individual

                                      -4-


Performance Award Amount." A Participant's maximum Individual  Performance Award
Amount is equal to the Total Bonus Opportunity at the Target  Performance level.
However,  in no event can the  amount of  Individual  Performance  Award  Amount
payable  result in a Participant  receiving a total bonus award greater than the
Total Bonus Opportunity, given the organizational performance level achieved.

         3.   Final Determination of Bonus
         Each  Participant's  bonus for a year shall be  equal to the sum of (i)
the  Organizational  Performance  Amount  for  such  Participant  and  (ii)  the
Individual Performance Award Amount for such Participant.

         4.  Chief Executive Officer's Discretionary Pool
         In each Plan Year, the Chief  Executive Officer of the Company,  in his
sole  discretion,  will be  authorized  to make awards from the Chief  Executive
Officer's  Discretionary Pool to any employee of the Company or its Subsidiaries
who is not a  Participant  in the Plan.  Each  Plan  Year,  the Chief  Executive
Officer,  with the approval of the  Committee,  will  establish the amount to be
allocated to the Chief Executive Officer's  Discretionary Pool.  Initially,  the
amount will be set at 1% of the aggregate base salaries of the exempt  employees
who are not  specified  Participants  under  this  Southwestern  Energy  Company
Incentive Compensation Plan.

         5.  Salary

                                      -5-


         Salary for purposes of  computing  bonuses  hereunder shall be equal to
the average annual base salary in effect for such Participant for the Plan Year.

E.   PAYMENT OF AWARD
         The total  bonus  payable  for any Plan Year  shall be  payable to each
Participant as soon as practicable after the date of determination of the amount
thereof and a minimum of 75 percent of such amount shall be payable in cash. The
balance shall be payable as the Committee may determine in its sole  discretion,
either  in  cash or in an  award  of  shares  of  common  stock  of the  Company
("Shares")  having an aggregate  Fair Market Value (FMV) equal to the balance of
the bonus.  The FMV shall be equal to the  closing  sale price of the  Company's
common stock as reported on the New York Stock Exchange for the day  immediately
preceding  the date of payment  of such  bonus.  The  Shares so issued  shall be
subject to the restrictions set forth below.

         The Committee may, in its  absolute discretion,  in connection with any
grant of Restricted Stock or at any time thereafter, grant a cash bonus, payable
promptly after the date on which the Participant is required to recognize income
for federal  income tax  purposes in  connection  with such grant of  Restricted
Stock,  in such  amounts as the  Committee  shall  determine  from time to time;
provided,  however  that in no event shall the amount of a cash bonus exceed the
FMV of the related  shares of Restricted  Stock on such date. A cash bonus shall
be subject to such  conditions as the Committee  shall  determine at the time of
the grant of such cash  bonus  and also  subject  to the  Company's  1993  Stock
Incentive Plan ("the Stock Plan").

                                      -6-


         Unless the  Committee otherwise  determines,  no bonus shall be payable
to any  Participant  who is not an active  employee of the Company or one of its
subsidiaries at the end of the Plan Year for which such bonus is payable.

F.   RESTRICTED SHARES AWARDED
         Any Restricted Shares awarded to a  Participant under this Plan will be
awarded  under the Stock Plan.  As such,  the terms and  provisions of the Stock
Plan shall apply and control any Restricted Shares awarded under this Plan.

         3.   Partial Payments:  Termination of Employment
         In the event of a Participant's  termination of employment,  other than
(a) a termination  by the Company (other than for Cause) on or after a Change in
Control,  (b)  voluntarily  by any  Participant  with whom the  Company  has not
entered into a severance agreement or any agreement in the nature of a severance
agreement for Good Cause (as defined above) on or after a Change in Control, (c)
voluntarily  by any  Participant  with  whom  the  Company  has  entered  into a
severance agreement or an agreement in the nature of a severance agreement on or
after a Change in Control, pursuant to the same conditions (if any) provided for
in such severance agreement for payment in the event of a voluntary  termination
of employment on or after a Change in Control,  (d) by the Participant's  death,
(e) by disability or (f) by retirement, any unpaid incentive compensation awards
shall be  subject to  forfeiture  at the  discretion  of the  Committee.  If the
termination is a result of retirement or Disability,  the  Participant  shall be
considered to have earned one-twelfth of the annual incentive compensation award
of a particular  year for each full month of  employment in the calendar year of
retirement.

         In the event of termination by the Company (other than for Cause) on or
after a Change in Control,  voluntarily by any Participant with whom the Company
has not entered into a severance  agreement or any  agreement in the nature of a
severance  agreement  for  Good  Reason  on or  after a Change  in  Control,  or
voluntarily  by any  Participant  with  whom  the  Company  has  entered  into a
severance agreement or an agreement in the nature of a severance  agreement,  on
or after a Change  in  Control  pursuant  to the  same  conditions  (if any) for
payment in the event of a  voluntary  termination  of  employment  on or after a
Change in Control provided for in such severance  agreement and in the event the
Participant's employment terminates prior to the end of any calendar year:

                                      -12-


(a)      The Participant's annual incentive  compensation  award for the year of
     termination  shall be determined  based on the number of full months in the
     calendar  year  in  which  the  termination  of  employment  occurs  during
     which  the  employee  was a  Participant  in this  Plan.  In the  event the
     Participant's  employment terminates prior to the end of any calendar year,
     the  performance  measures  used  in  determining  a  Participant's  annual
     incentive   compensation   award  shall  be   determined   by   annualizing
     Southwestern  Energy  Company's  results  to  date  with  respect  to  each
     Performance  Measure.  Each of the Performance Measures for such incomplete
     calendar year for the respective Performance Unit (i.e. Corporate, Utility,
     E&P or  Marketing)  shall be deemed  to be  Southwestern  Energy  Company's
     projected Performance Measures (i.e. Cash Flow, EPS, G&A, Production, etc.)
     for such  calendar  year (as  reflected in  Southwestern  Energy  Company's
     Annual Budget for such calendar year, prepared in the immediately preceding
     calendar  year) plus or minus a percentage  of such  projected  Performance
     Measure,  equal to the percentage by which  Southwestern  Energy  Company's
     actual annualized Performance Measure during such incomplete calendar year,
     exceeds  or is  exceeded  by the  projected  Performance  Measure  for such
     incomplete calendar year.

(b)      The Individual  Performance Award Amount for such  Participant shall be
     the Compensation Committee's most recent  estimation of such  Participant's
     performance  for the  calendar year in  which the  Participant's employment
     terminates  or, if there  shall be no such  estimation  and the Participant
     was a  Participant in the Plan in the immediately  preceding calendar year,
     the Individual  Performance  Award  Amount  for such  Participant  for such
     immediately preceding calendar year.

                                      -13-


         For all purposes  under the Plan, on or after a Change in Control,  the
term Compensation  Committee shall mean the Compensation  Committee of the Board
as it existed immediately prior to such Change in Control.

H.   NO VESTED RIGHTS
         Neither  the  adoption  of the Plan nor any  action of the Board or the
Committee  shall  be  deemed  to give  any  employee  any  right  to be  granted
participation in the Plan.  Nothing contained in the Plan shall confer any right
upon any employee  concerning the continuation of employment with the Company or
interfere in any way with the right of the Company to terminate  his  employment
at any time.  Nothing in the Plan shall be construed to prevent the Company from
taking any corporate  action which is deemed by the Company to be appropriate or
in its best interest,  whether or not such action will have an adverse effect on
the  Plan  or any  Participant  or any  award  made  thereunder.  No  employees,
beneficiaries  or other person  shall have any claim  against the Company or any
Subsidiary as a result of any action and no Participant  shall have any claim or
legal right to a bonus  hereunder  until such time as the  bonuses are  actually
paid pursuant to Section E hereof.

I.   NON-ASSIGNMENT
         The interest of any Participant  under the Plan shall not be assignable
either by voluntary or involuntary assignment or by operation of law.

J.   TERM OF THE PLAN
         Awards may be granted  pursuant  to this Plan for any year ending on or
before  December 31, 2009 unless the Plan is sooner  terminated  by the Board of
Directors.

                                      -14-


K.   AMENDMENTS
         The Board may, from time to time, amend, alter,  suspend or discontinue
the Plan or alter or amend any and all awards of Shares granted thereunder prior
to the issuance thereof.  The power of the Board to amend the Plan shall include
the power to amend the Plan,  without the approval of  shareholders,  to provide
that all bonuses shall be payable in cash.
