                (i) the Company is duly incorporated, validly existing and in
           good standing under the laws of the State of Delaware and is
           qualified to do business as a foreign corporation and is in good
           standing in the States of Colorado, Kansas, Louisiana, Montana,

                                        2
   3
 
                (iii) this Amendment, assuming due authorization, execution and
           delivery hereof by the Banks and the Agent, constitutes a valid and
           binding agreement of the Company, enforceable in accordance with its
           terms, except as (x) the enforceability thereof may be limited by
           bankruptcy, insolvency or similar laws affecting creditors' rights
           generally and (y) rights of acceleration and the availability of
           equitable remedies may be limited by equitable principles of general
           applicability;
 
                (iv) the execution, delivery and performance by the Company of
           this Amendment will not (x) conflict with the restated certificate of
           incorporation or by-laws of the Company, each as in effect on the
           date of such opinion, (y) contravene any applicable provision of any
           applicable law or applicable order or (z) conflict with any provision
           of any indenture, loan agreement or other similar agreement or
           instrument known to such counsel (having made due inquiry with
           respect thereto) binding on the Company or affecting its property;
 
                (v) no authorization, consent or approval of any governmental
           body or agency of the State of Texas or the United States of America
           which has not been obtained is required in connection with the
           execution, delivery and performance by the Company of this Amendment;
           and
 
                (vi) to the knowledge of such counsel (having made due inquiry
           with respect thereto), there is no proceeding pending or threatened
           before any court or administrative agency which, in the opinion of
           such counsel, will result in a final determination which would have
           the effect of preventing the Company from carrying on its business or
           from meeting its current and anticipated obligations on a timely
           basis.
 
             In rendering such opinion, the General Counsel of the Company shall
        opine only as to matters governed by the Federal laws of the United
        States of America, the laws of the State of Texas and the General
        Corporation Law of the State of Delaware and such counsel may state that
        he has relied on certificates of state officials as to qualification to
        do business and good standing certificates of officers of the Company
        and other sources believed by him to be responsible; and
 
             (c) Duly executed counterparts hereof signed by the Company, the
        Agent and each of the Banks (or, in the case of any party as to which an
        executed counterpart shall not have been received, the Agent shall have
        received telegraphic, telex or other written confirmation from such
        party of execution of a counterpart hereof by such party).
 
          4. Except as amended hereby, the Agreement shall continue in full
     force and effect.
 
          5. This Amendment shall be governed by, and construed in accordance
     with, the laws of the State of New York.
 
          6. This Amendment may be signed in any number of counterparts, each of
     which shall be an original, with the same effect as if the signatures
     thereto and hereto were upon the same instrument.
 
     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed by their respective officers thereunto duly authorized as of the day
and year first above written.

     For purposes of this Schedule, the following terms have the following
meanings:
 
        "Level" refers to the determination of which of Level I, Level II, Level
     III, Level IV or Level V exists at any date. The higher rating of S&P or
     Moodys will determine the Level to be used.
 
          "Level I" exists at any date if, at such date, the Company's long-term
     debt is rated A- or higher by S&P or A3 or higher by Moodys.
 
          "Level II" exists at any date if, at such date, the Company's
     long-term debt is rated BBB+ by S&P or Baa1 by Moodys.
 
          "Level III" exists at any date if, at such date, the Company's
     long-term debt is rated BBB by S&P or Baa2 by Moodys.
 
          "Level IV" exists at any date if, at such date, the Company's
     long-term debt is rated BBB- by S&P or Baa3 by Moodys.
 
          "Level V" exists at any date if, at such date, the Company's long-term
     debt is rated below BBB- by S&P or below Baa3 by Moodys.
 
     In the event a rating is not available from either Moodys or S&P, such
rating agency will be deemed to have assigned its lowest rating.
 
     The credit ratings to be utilized for purposes of this Schedule are those
assigned to the senior unsecured long-term debt securities of the Company 
without third-party credit enhancement, and any rating assigned to any other 
debt securities of the Company shall be disregarded. The rating in effect at 
any date is that in effect at the close of business on such date.

           delivered by the Company;
 
                (iii) this Amendment, assuming due authorization, execution and

                (v) no authorization, consent or approval of any governmental
           body or agency of the State of Texas or the United States of America

           before any court or administrative agency which, in the opinion of

        and other sources believed by him to be responsible; and
 
             (c) Duly executed counterparts hereof signed by the Company, the
        Agent and each of the Banks (or, in the case of any party as to which an
        executed counterpart shall not have been received, the Agent shall have
        received telegraphic, telex or other written confirmation from such
        party of execution of a counterpart hereof by such party).
 
          4. Except as amended hereby, the Agreement shall continue in full
     force and effect.
 
          5. This Amendment shall be governed by, and construed in accordance
     with, the laws of the State of New York.
 
          6. This Amendment may be signed in any number of counterparts, each of
     which shall be an original, with the same effect as if the signatures
     thereto and hereto were upon the same instrument.

     For purposes of this Schedule, the following terms have the following
meanings:
 
        "Level" refers to the determination of which of Level I, Level II, Level
     III, Level IV or Level V exists at any date. The higher rating of S&P or
     Moodys will determine the Level to be used.
 
          "Level I" exists at any date if, at such date, the Company's long-term
     debt is rated A- or higher by S&P or A3 or higher by Moodys.
 
          "Level II" exists at any date if, at such date, the Company's
     long-term debt is rated BBB+ S&P or Baa1 by Moodys.
 
          "Level III" exists at any date if, at such date, the Company's
     long-term debt is rated BBB by S&P or Baa2 by Moodys.
 
          "Level IV" exists at any date if, at such date, the Company's
     long-term debt is rated BBB- by S&P or Baa3 by Moodys.
 
          "Level V" exists at any date if, at such date, the Company's long-term
     debt is rated below BBB- by S&P or below Baa3 by Moodys.
 
     In the event a rating is not available from either Moodys or S&P, such
rating agency will be deemed to have assigned its lowest rating.
 
     The credit ratings to be utilized for purposes of this Schedule are those
assigned to the senior unsecured long-term debt securities of the Company
without third-party credit enhancement, and any rating assigned to any other
debt securities of the Company shall be disregarded. The rating in effect at any
date is that in effect at the close of business on such date.
