      FOR  VALUE  RECEIVED, Strategic Energy, L.L.C., a  Delaware

such  other  place as the holder hereof may, from time  to  time,
designate  in  writing, the principal sum  of  Ten  Million  Nine
Hundred  Seventy-Three Thousand Thirty-Five Dollars and No  Cents
($10,973,035.00), ON DEMAND, together with interest on the unpaid
principal balance hereof at a variable rate of interest per annum
equal to the "Prime Rate" as such rate is publicly announced from
time  to  time  by PNC Bank, National Association  ("PNC").   Any
change  in  such rate of interest shall be effective  as  of  the
opening  of  business  on the date on which PNC  establishes  the
changed "Prime Rate."

      Any amount hereunder which is not paid when due, whether at
stated  maturity,  by  acceleration  or  otherwise,  shall   bear
interest from the date when due until paid at the lesser  of  (i)
the foregoing rate per annum plus three (3) percentage points, or
(ii) the maximum rate permitted by law.

      Maker  and  all  persons  who become  liable  hereon  waive
presentment for payment, demand, protest, notice of protest,  and
notice  of dishonor.  In addition, the holder hereof may, without
notice  and  without release of the liability  of  Maker  or  any
maker, endorser, surety and guarantor, add or release one or more
of such parties or release any security in whole or in part.  The
holder  hereof  shall  not be liable for, or  be  prejudiced  by,
failure to collect or for lack of diligence in bringing suit upon
this Note or any modification or renewal thereof.

      Maker  will  pay  on  demand all costs  of  collection  and
attorneys'  fees and expenses incurred or paid by the  holder  in
enforcing  the conditions of this Note (collectively,  "Costs  of
Collection").

       All   payments   made  hereunder,  whether   a   scheduled
installment,  prepayment, or payment as a result of acceleration,
shall be allocated first to accrued but unpaid interest, next  to
any  Costs  of Collection, and then to installments of  principal
remaining  outstanding  hereunder  first  to  principal   amounts
overdue  then  to  principal amounts currently due  and  then  to
installments of principal due in the future in the inverse  order
of their maturity.

       This  Note  shall  be  governed  by,  and  construed   and
interpreted in accordance with, the laws of the State of  Kansas,
without  reference to conflict of laws principles of said  state.
Any  amendments, changes or modifications to this Note  shall  be
made only in writing signed on behalf of the parties sought to be
bound by a duly authorized officer or agent thereof.
