Dear
      Frederick:





When
      countersigned by you, this letter will serve as an amendment (referred to here
      as “ **Amendment
      No. 2** ”)
      to
      your existing change in control agreement with KCS Energy, Inc. (the
“ **Company** ”)
      dated
      May 1, 2003, as amended by Amendment No.1 (the “ **Original
      Agreement** ”).





1.  **Cash
      Payment** **.** Section
      2.1.1 of the Original Agreement is amended by deleting that provision in its
      entirety and substituting the following terms:




**Cash
      Payment.** The Company shall pay to Executive: (i) an amount equal to one (1) times the
      greater of (a) the Executive’s annual base salary in effect as of the
      Termination Date or (b) the Executive’s annual base salary in effect immediately
      preceding the Change in Control; plus (ii) an amount equal to one (1) times
      the
      greater of (a) the amount of any cash bonus payable to the Executive for the
      year in which the Termination Date falls (provided that if the Executive’s bonus
      for such year has not been determined as of the Termination Date, then the
      amount of the bonus shall be determined as if the Executive earned 100% of
      the
      targeted bonus for such year) or (b) the amount of the last cash bonus paid
      to
      the Executive prior to the Change in Control; plus (iii) the amount of any
      earned but unpaid salary as of the Termination Date; plus (iv) the amount of
      any
      cash bonus payable to the Executive pursuant to Section 3 to the extent not
      paid
      prior to the Termination Date; plus (v) an amount equal to the greater of (a)
      a
      pro rata amount of the Executive’s targeted bonus for the year in which the
      Termination Date falls or (b) such bonus for such year as may be determined
      by
      the compensation committee or the board of directors of the Company in their
      sole discretion; plus (vi) the amount of any accrued but unpaid vacation pay
      through the Termination Date.




2.  **Bonus
      Payment** **.** New
      Section 3 is added to the Original Agreement to provide as follows:




**Bonus
      Payment** **.** (a) **** In
      the
      event of a Change in Control, if prior to the Change in Control a bonus for
      the
      Executive has been determined by the compensation committee or the board of
      directors of the Company for the year immediately preceding the year in which
      a
      Change in Control occurs, then the Executive shall receive a bonus payment
      for
      such year in the amount so determined.





(b)
       In the event of a Change in Control, if prior to the Change in Control the
      Executive has not been awarded a bonus for the year immediately preceding the
      year in which the Change in Control falls by the compensation committee or
      the
      board of directors of the Company, then the Executive shall receive a bonus
      payment for such preceding year in an amount equal to the greater of (i) 100%
      of
      Executive’s targeted bonus payment for such year or (ii) the bonus
      for

such
      preceding year determined after the Change in Control by the compensation
      committee or the board of directors of the Company under the bonus plan in
      effect immediately prior to the Change in Control.





(c)
       Subject to the provisions of Section 4(b), any bonus payable to Executive
      pursuant to Section 3(a) shall be paid by the later of (i) the date that is
      2-1/2 months after the end of the calendar year immediately preceding the
      calendar year in which the Change in Control occurred and (ii) the date that
      is
      2-1/2 months after the end of the Company’s taxable year immediately preceding
      the Company’s taxable year in which the Change in Control occurred, or as soon
      after the later of such dates as administratively feasible, but in any event
      before the end of the calendar year in which the Change in Control
      occurred.





(d)
       Subject to the provisions of Section 4(b), any bonus payable to the
      Executive pursuant to Section 3(b) shall be paid by the later of (i) the date
      that is 2-1/2 months after the end of the calendar year in which the Change

      the Change in Control occurred.





3.  **Payment
      Terms** .
      Section
      3 of the Original Agreement is renumbered as Section 4 and is amended by
      deleting that Section in its entirety and substituting the following new Section
      4:





**Payment
      Terms** **.** (a)
      Except as provided by the remaining provisions of this Section 4, all payments
      to the Executive required to be made pursuant to Section 2.1.1 shall be made
      by
      the Company within five (5) days after the Termination Date, and all payments
      to
      the Executive required to be made under clause (b) of the last sentence of
      Section 2.1.3 shall be made within five (5) days of the Executive’s furnishing
      the Company with evidence of the cost of such insurance, provided that the
      Executive furnishes such evidence within six (6) months after the Termination
      Date, in each case by wire transfer or Company check at the Executive’s option.
      All payments required to be made to the Executive pursuant to this Agreement
      shall be subject to the withholding of such taxes as may be required by
      law.





(b)
       In the event that any payment made pursuant to this Agreement is determined, in
      whole
      or in part, to
      constitute “nonqualified deferred compensation” (“NQDC”) within the meaning of
      Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and
      Executive is a specified employee as defined in Section
      409A(a)(2)(B)(i) of the Code, then the portion (which may be all) of such
      payment that constitutes NQDC will not be paid before the date which is six
      (6)
      months after the Executive’s “separation from service” (as such term is defined
      in Section 409A of the Code). The
      determination of whether and what amount of such payment constitutes NQDC and
      whether Executive is a specified employee within the meaning of Section
      409A(a)(2)(B)(i) of the Code shall be made by the board of directors of the
      Company in consultation with legal counsel, and any such determination shall
      be
      final and binding on the Company and the Executive. The Company makes no
      representation as to whether any such payment or any part thereof constitutes
      or
      may constitute NQDC. Neither the Company, nor any of its directors, officers,
      employees, agents, or professional advisers shall have any liability to
      Executive or any other person for any amounts incurred by the Executive or
      such
      other

person
      by
      reason of the determination made by the board of directors of the Company
      pursuant to this Section 4(b) or any action taken or omitted by the board of
      directors of the Company, the Company or any of the Company’s directors,
      officers, employees, agents, or professional advisers in the course of or as
      a
      result of making such determination.





4.  **Original
      Agreement Ratified** **.** In all
      other respects, the Original Agreement remains in effect, and is ratified by
      you
      and by the Company.
