          on the Company or affecting its property;

          (v)   no  authorization, consent  or  approval  of  any

     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).

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.

     For  purposes of this Schedule, the following terms have the

     "Level"  refers to the determination of which  of  Level  I,
Level II, Level III, Level IV, Level V or Level VI exists at  any

Level to be used.

long-term  debt is rated A or higher by S&P or A2  or  higher  by
Moodys.
     
     "Level  II"  exists  at  any date  if,  at  such  date,  the

     "Level  III"  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  IV"  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 V" 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  VI"  exists  at  any date  if,  at  such  date,  the
Company's long-term debt is rated below BBB- by S&P and  Baa3  by
Moodys.

     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.
