          and delivered by the Company;

          (iii)      this  Amendment, assuming due authorization,

          Agent, constitutes a valid and binding agreement of the
          Company,  enforceable  in accordance  with  its  terms,
          subject   to  applicable  bankruptcy,  insolvency   and
          similar laws affecting creditors' rights generally  and
          equitable principles of general applicability;

          (iv)  the  execution, delivery and performance  by  the

          opinion, (y) contravene any applicable provision of any
          applicable law or applicable order or (z) conflict with

          on the Company or affecting its property;

          (v)   no  authorization, consent  or  approval  of  any

          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

     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).

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.

          (ii)  no event has occurred and is continuing, or would

          of notice or the lapse of time, or both; and

          (iii)      the  Company is in compliance with  all  the
          terms, covenants and conditions of the Agreement  which

     the Amendment Date, the effect that:

          (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

          (iii)      this  Amendment, assuming due authorization,

          Agent, constitutes a valid and binding agreement of the
          Company,  enforceable  in accordance  with  its  terms,
          subject   to  applicable  bankruptcy,  insolvency   and
          similar laws affecting creditors' rights generally  and
          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

          opinion, (y) contravene any applicable provision of any
          applicable law or applicable order or (z) conflict with

          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

          obtained  is required in connection with the execution,

          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.
