AMENDMENT NUMBER 1
                                       TO THE
                             SOUTHWESTERN ENERGY COMPANY
                            SUPPLEMENTAL RETIREMENT PLAN


     WHEREAS,  the  Southwestern  Energy Company (the  "Company")  maintains the
Southwestern Energy Company Supplemental Retirement Plan (the "SERP"); and

     WHEREAS, it is desirable to amend the SERP to provide an offset to benefits
payable to a participant or a participant's  beneficiary  under the SERP for any
benefits provided under any split-dollar  life insurance  agreement between such
participant  and the Company  and to change the timing of the  benefit  payments
under the SERP.

     NOW, THEREFORE, effective February 1, 1996, the SERP is amended as follows:

                                     ARTICLE III
                                  UNFUNDED BENEFITS

                  1.  Section B.1 is amended in its entirety to read as follows:

                           "The  Actuarial  Equivalent  of  a  Participant's  or
                  Beneficiary's Unfunded Benefit under the Plan shall be paid to
                  the  Participant  or  Beneficiary  in a single lump sum on the
                  later of (a) the first day of the month following the one-year
                  anniversary  of the  Participant's  termination  of employment
                  with the Company or (b) the date that benefit  payments  under
                  the Pension Plan to such Participant or Beneficiary  commence;
                  provided,  however,  that a  Participant  may  elect  that the
                  Actuarial   Equivalent  of  his  (or,  in  the  event  of  the
                  Participant's death, his Beneficiary's) Unfunded Benefit under
                  the Plan be paid in the form of an annuity,  beginning  at the
                  same  time  and in the  same  form  as  the  Participant's  or
                  Beneficiary's  benefit  under  the  Pension  Plan is paid,  by
                  filing  a  written  election  with  the  Committee,  on a form
                  provided  by the  Committee,  at least  one year  before  such
                  Participant's  termination of employment with the Company.  No
                  election or revocation of an election shall be effective if it
                  is received by the  Committee  less than one year prior to the
                  Participant's termination of employment."





                                            1





         2.  A new Section D is added to read as follows:

                  "D. Offset for Certain Benefits Payable Under Split-Dollar 
                      Life Insurance Agreements.

                           1.       Offset Value.

                           Some of the  Participants  under  this  Plan own life
                  insurance policies (the "Policies")  purchased on their behalf
                  by the  Corporation.  The exercise of  ownership  rights under
                  these Policies by each  Participant  is,  however,  subject to
                  certain  conditions  (set forth in a  "Split-Dollar  Insurance
                  Agreement"   between  the  Participant  and  the  Corporation,
                  pursuant to which the Corporation holds a security interest on
                  the  Policy)  and,  if  the  Participant  fails  to  meet  the
                  conditions  set  forth  in  the  Split-Dollar  Life  Insurance
                  Agreement,  the Corporation may exercise its security interest
                  in the  Policy  and  cause  the  Participant  to lose  certain
                  benefits  under the  Policy.  In the event that a  Participant
                  satisfies  the  condition  specified  in Section 4 or 5 of the
                  Split-Dollar Life Insurance Agreement, so that the Participant
                  or his or her beneficiary  becomes entitled to exercise rights
                  free from the  Corporation's  security  interest  under one of
                  those  sections,  or the  Corporation's  security  interest is
                  otherwise   released,   the  value  of  those  benefits  shall
                  constitute an offset to the  Participant's  Unfunded  Benefits
                  otherwise  payable  under this Plan.  As the case may be, this
                  offset  (the  "Offset  Value")  shall  be  equal  to the  cash
                  surrender  value of the  Policy  at the  time the  Participant
                  becomes  entitled to exercise  rights free from the  Company's
                  security interest,  or in the case of the Participant's death,
                  the  death  benefits  payable  to the  beneficiary  under  the
                  Policy. The Actuarial  Equivalent of the Offset Value shall be
                  compared to the Actuarial  Equivalent of the Unfunded Benefits
                  payable under this Plan (the "Plan Value"), and the Plan Value
                  shall be reduced  by the  Actuarial  Equivalent  of the Offset
                  Value at the time and in the manner  described  in Section D.2
                  or Section D.3 of this Article III.

                           2.       Manner and Calculation of Payment.

                           If,   at  the   time   the   Participant   terminates
                  employment, the Plan Value exceeds the Actuarial Equivalent of
                  the  Offset  Value,  the  excess  of the Plan  Value  over the
                  Actuarial  Equivalent of the Offset Value shall be paid to the
                  Participant  or  Beneficiary  at the  time  and in the  manner
                  provided  under  Section B.1 of this  Article  III;  provided,
                  however, that if such excess is less than $10,000, such excess
                  shall be paid immediately to the Participant or Beneficiary in
                  a cash lump sum.  For this  purpose,  the Plan Value  shall be
                  calculated by assuming  that the  Participant  or  Beneficiary
                  receives or commences  receiving  benefits under this Plan and
                  the  Pension  Plan on the  earliest  date that  such  benefits
                  become payable.



                                            2





                           3.       Payment of Certain Benefits.

                           If the  policy  described  in  Section  D.1  of  this
                  Article III insures the life of an  individual  other than the
                  Participant (the "Insured  party"),  and if such Insured Party
                  dies prior to the Participant's becoming eligible for benefits
                  under  the  Plan,  and  if  the   Participant  or  Beneficiary
                  subsequently becomes eligible for benefits hereunder, the Plan
                  Value (as  defined in Section D.1 of this  Article  III) shall
                  then be offset by the Actuarial Equivalent of the amount equal
                  to the death benefit previously paid to the Participant or the
                  Participant's  beneficiary  pursuant to the Split-Dollar  Life
                  Insurance  Agreement  divided by the Tax Adjustment Factor (as
                  defined  below).  Any remaining Plan Value shall  thereupon be
                  paid to the Participant or Beneficiary in a cash lump sum.

                           4.       Tax Adjustment Factor.

                           For  purposes of this  Section D of Article  III, Tax
                  Adjustment  Factor  shall  mean a  number,  determined  by the
                  Committee,  which  is equal  to one  minus  the sum of (a) the
                  highest  marginal  federal  personal  income  tax rate then in
                  effect and (b) the effective highest marginal state income tax
                  rate in the state in which the Participant  resides, net after
                  the  effect of the  deduction  for such  state  income tax for
                  federal income tax purposes."


     IN WITNESS  WHEREOF,  the Company has caused this instrument to be executed
by its duly authorized officers this 1st day of February, 1996.
