Item 1.       Description of Registrant's Securities to be Registered.

              On March 15,  2002 (the  "Second  Amendment  Date"),  the Board of
Directors of  Southwestern  Energy  Company (the  "Company")  approved,  and the
Company has entered into, an Amendment No. 1 ("Amendment  No. 1") to its Amended
and  Restated  Rights  Agreement,  dated  as of  April  12,  1999  (the  "Rights
Agreement"),  between the Company and First  Chicago  Trust  Company of New York
(the "Rights Agent"), pursuant to which the terms of the outstanding rights (the
"Rights")  were  amended and  restated.  The  outstanding  Rights are  currently
evidenced (on the basis of one Right for each outstanding share) by the existing
certificates  for  outstanding  shares of common stock,  $0.10 par value, of the
Company  (the  "Common  Stock"),  and  are  not  exerciseable  and do not  trade
separately  from such  shares.  The  summary  below  describes  the Rights as so
amended by Amendment No. 1.

              Each Right, when  exercisable,  will entitle the registered holder
to purchase from the Company one share of the Company's  Common Stock at a price
of $40 per share (the "Purchase Price"), subject to adjustment.

              Until the close of business  on the  earliest of (i) the tenth day
after a  public  announcement  that  (A) a person  or  group  of  affiliated  or
associated  persons has acquired,  or obtained the right to acquire,  beneficial
ownership (as defined) of 15% or more of the outstanding  shares of Common Stock
of the Company (other than pursuant to a tender offer for all outstanding shares
of Common  Stock at the price and on terms  approved  by the Board of  Directors
based upon a prior recommendation of the Independent Directors (as defined) at a
time when there are at least two Independent  Directors or solely as a result of
a  reduction  of the  number  of shares of  Common  Stock  outstanding  due to a
repurchase of shares by the Company), (B) any person or group which beneficially
owned 15% of the  outstanding  shares on the date of the  Rights  Agreement,  or
which acquired beneficial ownership of 15% of the outstanding shares as a result
of any  repurchase  of shares by the  Company,  thereafter  acquired  beneficial
ownership of additional shares constituting 1% or more of the outstanding shares
of Common Stock or (C) the Board of Directors  determines that a person or group
beneficially  owning  10% or more of the Common  Stock  presents a threat to the
best interests of the Company or its  shareholders  and is therefore an "Adverse
Person" (any person or group  referred to in this clause (i) being an "Acquiring
Person");  and  (ii)  the  tenth  Business  Day  (or  such  later  day as may be
determined by action of the Board of Directors of the Company prior to such time
as any Person  becomes an Acquiring  Person) after the date of the  commencement
of, or the first public  announcement  of the intent of any person (other than a
Company Entity (as defined)) to commence (which intention to commence remains in
effect for five  business  days after such  announcement)  a tender or  exchange
offer by any Person (other than a Company  Entity) to acquire (when added to any
shares as to which such Person is the beneficial owner immediately prior to such
commencement)  beneficial ownership of 15% or more of the issued and outstanding
shares of Common Stock (the earlier of such dates being called the "Distribution
Date"),  the Rights  will be  evidenced,  with  respect to any of the  Company's
Common Stock  certificates  outstanding  as of the Record  Date,  by such Common
Stock certificate.

              The Rights Agreement  provides that, until the Distribution  Date,
the Rights will be transferred  with and only with the Common Stock.  New Common
Stock certificates issued after the Record Date upon transfer or new issuance of
the Common Stock will contain a

                                       2

notation incorporating the Rights Agreement by reference. Until the Distribution
Date,  the  surrender  for  transfer  of any of the  Common  Stock  certificates
outstanding as of the date of the Rights Agreement  (whether or not containing a
notation  contemplated by the original Rights  Agreement dated May 5, 1989) will
also  constitute  the  transfer of the Rights  associated  with the Common Stock
represented by such  certificate  and the number of Rights  associated with each
share of Common  Stock  shall be  proportionately  adjusted  in the event of any
dividend in Common  Stock on the Common  Stock or  subdivision,  combination  or
reclassification of the Common Stock (except as otherwise provided in the Rights
Agreement).  As soon as practicable  following the Distribution  Date,  separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of  record  of the  Common  Stock as of the  close of  business  on the
Distribution Date and such separate certificates alone will evidence Rights.

              The Rights are not exercisable  until the  Distribution  Date. The
Rights will expire on April 11, 2009,  unless earlier redeemed by the Company as
described  below or unless  further  extended  pursuant to an  amendment  in the
Rights Agreement as described below.

              The  Purchase  Price  payable,  and the number of shares of Common
Stock or other securities or property issuable,  upon exercise of the Rights are
subject to adjustment from time to time to prevent  dilution (i) in the event of
a stock dividend on, or a subdivision,  combination or reclassification  of, the
Common Stock,  (ii) upon the grant to holders of Common Stock of certain  rights
or warrants to subscribe for shares of Common Stock or convertible securities at
less  than the  current  market  price  of the  Common  Stock or (iii)  upon the
distribution  to holders of Common Stock of evidences of  indebtedness or assets
(excluding regular periodic cash dividends or dividends payable in Common Stock)
or of subscription rights or warrants (other than those referred to above).

              In  the  event  that,   at  any  time  after  the  Rights   become
exercisable,  the Company is acquired in a merger or other business combination,
proper  provision shall be made so that each holder of a Right shall  thereafter
have the  right  to  receive,  upon the  exercise  thereof  at the then  current
exercise  price of the  Right,  that  number of  shares  of common  stock of the
surviving company (or its parent company or other  controlling  entity) which at
the time of such transaction would have a market value of two times the exercise
price of the Right.  In the event that any person  becomes an Acquiring  Person,
the Rights  Agreement  provides that proper provision would be made so that each
holder  of a  Right,  other  than  the  Acquiring  Person  (whose  Rights  would
thereafter be null and void) and certain of its  transferees,  would  thereafter
have the right to  receive  upon  exercise  that  number of shares of the Common
Stock having a market value of two times the exercise price of the Right.

              With certain exceptions,  no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional  shares will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Common Stock
on the last trading date prior to the date of exercise.

              At any time prior to the close of business on the date that Rights
holders  become  entitled  to  purchase  Common  Stock of the Company (or of the
surviving  entity after a merger with the Company)  with a market value of twice
the Purchase Price (as described  above),  the Board of Directors of the Company
may redeem the Rights in whole, but not in part, at a price of

                                       3

$.01 per Right (payable in cash, shares of Common Stock or other consideration),
appropriately  adjusted to reflect any stock  split,  stock  dividend or similar
transaction   occurring  after  the  date  hereof  (the   "Redemption   Price").
Immediately upon the action of the Board of Directors of the Company electing to
redeem the Rights (unless otherwise  specified in such Board action),  the right
to  exercise  the Rights  will  terminate  and the only right of the  holders of
Rights will be to receive the Redemption Price.

              Upon the first public announcement (including, without limitation,
the filing of a report  pursuant to the Securities  Exchange Act of 1934) by the
Company  or an  Acquiring  Person  containing  information  indicating  that  an
Acquiring  Person has become such and prior to the  acquisition  by an Acquiring
Person  of 50% or more of the  Common  Stock  then  outstanding,  the  Board  of
Directors may, at its option,  exchange all or part of the then  outstanding and
existing  Rights (other than Rights owned by such  Acquiring  Person which shall
become void) for Common Stock at an Exchange  Ratio of one share of Common Stock
per Right (subject to adjustment) (the "Exchange  Ratio").  Immediately upon the
action of the Board of Directors of the Company electing to exchange the Rights,
the right to  exercise  the  Rights  will  terminate  and the only  right of the
holders of Rights will be to receive  that  number of shares of Common  Stock or
Common  Stock  equivalents  equal to the  number of Rights  held by such  holder
multiplied by the Exchange Ratio.

              Until a Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of the Company,  including,  without  limitation,  no
right to vote or to receive dividends.

              At any time prior to the time that an Acquiring  Person has become
such, the Company may amend the Rights  Agreement and the terms of the Rights in
any manner deemed necessary or desirable.  Thereafter,  the Rights Agreement and
the  terms  of  the  Rights  may  be  amended  by  the  Company   under  certain
circumstances, but not in any manner that adversely affects the interests of the
holders of the Rights (other than an Acquiring Person).

              The Rights  Agreement,  which includes as exhibits the form of the
Amended  Right  Certificate  and the Summary of the  Amended  Rights to Purchase
Common  Stock,  and  Amendment  No.  1, are  attached  hereto  as  exhibits  and
incorporated  by  reference  herein.  The  foregoing  description  of the Rights
Agreement  and the  amended  Rights  does  not  purport  to be  complete  and is
qualified in its entirety by reference to the Rights Agreement.

                  TO THE AMENDED AND RESTATED RIGHTS AGREEMENT

              This Amendment No. 1 to the Amended and Restated Rights  Agreement
(this  "Amendment"),  dated as of March 15, 2002,  between  Southwestern  Energy
Company, an Arkansas  corporation (the "Company"),  and EquiServe Trust Company,
N.A.,  successor to The First National Bank of Chicago (the "Rights Agent"). All
capitalized  terms used in this  Amendment and not otherwise  defined shall have
the respective  meanings set forth in the Amended and Restated Rights  Agreement
(as defined below).
                              W I T N E S S E T H:
                               - - - - - - - - - -
              WHEREAS,  on May 5, 1989 (the  "Declaration  Date"),  the Board of
Directors  of the  Company  authorized  and  declared  a  dividend  of one right
representing  the right to purchase one share of Common Stock upon the terms and
subject to the  conditions set forth in a Rights  Agreement,  dated May 5, 1989,
between the Company and the Rights Agent (the "1989 Rights  Agreement") for each
outstanding share of common stock,  $2.50 par value, of the Company  outstanding
at the close of business on May 19, 1989 (the "Record Date"), and authorized the
issuance  of one Right with  respect  to each  share of Common  Stock that shall
become  outstanding  between the Record Date and the earlier of the Distribution
Date and the Expiration  Date,  each Right initially  representing  the right to
purchase one share of Common Stock upon the terms and subject to the  conditions
hereinafter set forth;

              WHEREAS,  the Company declared a three-for-one stock split in 1993
and, in connection with such split,  the number of Rights was adjusted  pursuant
to Section 11 of the 1989 Rights Agreement such that each certificate for Common
Stock  outstanding as of the date of this Amended and Restated Rights  Agreement
also represents one Right under the 1989 Rights Agreement representing the right
to  purchase  one  share of Common  Stock  upon the  terms  and  subject  to the
conditions set forth in the 1989 Rights Agreement;

              WHEREAS,  on April  12,  1999,  in  compliance  with the  terms of
Section 27 of the 1989  Rights  Agreement,  the  Company  and the  Rights  Agent
entered into an Amended and Restated Rights Agreement (the "Amended and Restated
Rights  Agreement")  which amended and restated the 1989 Rights Agreement in its
entirety in order to extend the Expiration Date until April 12, 2009 and to make
other changes and provisions  that they  determined  were necessary or desirable
and did not adversely affect the interests of the holders of the Rights;

              WHEREAS,  the Company  wishes to amend the  Amended  and  Restated
Rights Agreement in order to eliminate the requirement of all required approvals
of Independent Directors;

              WHEREAS, in compliance with the terms of Section 27 of the Amended
and Restated Rights Agreement, the Company has (i) delivered to the Rights Agent
a certificate from an appropriate  officer of the Company which states that this
Amendment  has been  approved  by the  Company's  Board of  Directors  and is in
compliance with the terms of Section 27 of the

                                       1

Amended and Restated  Rights  Agreement and (ii)  instructed the Rights Agent to
execute this Amendment;

              NOW,  THEREFORE,  in  consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

              Section l. Definitions.

              (a) The definition of "Approved  Offer"  contained in subparagraph
(d) of Section 1 of the Amended and Restated Rights  Agreement is hereby amended
in its entirety to read as follows:

              ""Approved  Offer"  shall mean a tender or exchange  offer for all
outstanding  shares of Common  Stock  that is at a price and on terms  approved,
prior to the  acceptance  for  payment of shares  under such  tender or exchange
offer,  by  the  Board  of  Directors  of  the  Company  based  upon  the  prior
recommendation of a majority of the board of directors."

              (b) The  references to the defined terms  "Independent  Directors"
and "Proposed  Acquiror"  contained in subparagraph  (m) of Section 1 are hereby
deleted.

              Section  2.  Redemption.  Subparagraph  (a) of  Section  23 of the
Amended and  Restated  Rights  Agreement  is amended in its  entirety to read as
follows:

              "(a) The Company may, by resolution of its Board of Directors,  at
its option,  at any time prior to the earlier of (x) the Stock  Acquisition Date
or (y) the close of business on the Final  Expiration  Date,  redeem all but not
less than all of the then outstanding  Rights at a redemption price of $0.01 per
Right, as such amount may be appropriately  adjusted to reflect any stock split,
stock dividend or similar  transaction  occurring after the date of this Amended
and Restated Rights Agreement (such redemption price being hereinafter  referred
to as the  "Redemption  Price").  The  Company  may , at  its  option,  pay  the
Redemption  Price in cash,  shares of Common Stock (based on the "current market
price",  as defined in Section 11(d)(i) hereof,  of the Common Stock at the time
of such Board resolution) or any other form of consideration  deemed appropriate
by the Board of Directors."

              Section 3. Exchange. Subparagraph (a) of Section 24 of the Amended
and Restated Rights Agreement is amended in its entirety to read as follows:

              "(a) The Board of Directors of the Company may, at its option,  at
any  time  after  the  Stock  Acquisition  Date  exchange  all  or  part  of the
then-outstanding  and  exercisable  Rights (which shall not include  Rights that
have become void pursuant to the  provisions of Section  11(a)(iii)  hereof) for
Common Stock (or Common Stock  Equivalents) at an exchange ratio of one share of
Common Stock per Right, appropriately adjusted to reflect any stock split, stock
dividend or similar  transaction  occurring  after the date of this  Amended and
Restated Rights Agreement (such exchange ratio being hereinafter  referred to as
the "Exchange Ratio").  Notwithstanding the foregoing, the Board of Directors of
the Company shall not be empowered to effect such exchange at any time after any
Person  (other  than  a  Company  Entity),  together  with  all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
Common Stock then outstanding."

                                       2


              Section 4.  Supplements and Amendments.  Section 27 of the Amended
and Restated Rights Agreement is amended in its entirety to read as follows:

              "The  Company  and the  Rights  Agent  shall,  if the  Company  so
directs,  from time to time  supplement  or amend  this  Agreement  without  the
approval  of any holders of Rights in order (i) to cure any  ambiguity,  (ii) to
correct or supplement any provision  contained  herein which may be defective or
inconsistent  with any other provisions herein (provided that any amendment made
pursuant to clause (i) or (ii) hereof after a Stock  Acquisition Date, shall not
materially  adversely affect the interests of the holders of Right  Certificates
(other than an Acquiring Person or any Affiliate or Associate  thereof)),  (iii)
prior to the Stock  Acquisition Date, to effect any other change or modification
which the  Company  may deem  necessary  or  desirable,  or (iv) after the Stock
Acquisition Date, to make any other provisions in regard to matters or questions
arising  hereunder  which the Company may deem  necessary or desirable and which
shall not adversely  affect the  interests of the holders of Right  Certificates
(other  than  an  Acquiring  Person  or any  Affiliate  or  Associate  thereof).
Notwithstanding  anything  contained  in this  Agreement to the  contrary,  this
Agreement  may not be  amended  or  supplemented  (x) to  reinstate  a right  of
redemption  if the  Rights  are  not  then  redeemable  or (y) to  decrease  the
Redemption Price. Upon the delivery of a certificate from an appropriate officer
of the Company  which states that the proposed  supplement or amendment has been
approved by the Company's Board of Directors and is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or amendment;
provided,  however,  that the Rights Agent may,  but shall not be obligated  to,
enter into any such  supplement or amendment that adversely  affects its rights,
duties or immunities under this Agreement.  Prior to the Distribution  Date, the
interests  of the  holders  of  Rights  shall be  deemed  to  coincide  with the
interests of holders of shares of Common Stock (other than an Acquiring  Person,
an Adverse Person or any Affiliate or Associate thereof)."

              Section 5.  Determinations  and Actions by the Board of Directors,
etc.  Section 31 of the Amended and Restated Rights  Agreement is amended in its
entirety to read as follows:

              "The Board of  Directors of the Company  shall have the  exclusive
power and authority to administer  this Agreement and to exercise all rights and
powers  specifically  granted to the Board of Directors or to the Company, or as
may  be  necessary  or  advisable  in  the  administration  of  this  Agreement,
including,  without  limitation,  the  right  and  power  to (i)  interpret  the
provisions of this Agreement,  and (ii) make all determinations deemed necessary
or  advisable  for the  administration  of this  Agreement  (including,  without
limitation,  a  determination  to redeem or not to redeem the Rights pursuant to
Section  23 hereof or to  supplement  or amend the  Agreement  and  whether  any
proposed  supplement or amendment adversely affects the interests of the holders
of Right Certificates and comports with the requirements of Section 27 hereof or
to find or to announce  publicly that any Person has become an Acquiring  Person
or an Adverse  Person).  For all purposes of this Agreement,  any calculation of
the  number of shares of Common  Stock or other  securities  outstanding  at any
particular time, including for purposes of determining the particular percentage
of such outstanding  shares of Common Stock or any other securities of which any
Person  is the  Beneficial  Owner,  shall  be made in  accordance  with the last
