      All  agreements between  the Maker  and the  holder hereof  are  hereby
 expressly limited so that  in no contingency or  event whatsoever shall  the
 amount paid,  or agreed  to be  paid,  to the  holder  hereof for  the  use,

 provision shall  be due  shall involve  transcending the  limit of  validity
 prescribed by  applicable  law,  then, ipso  facto,  the  obligation  to  be

 owing thereunder and  not to the  payment of interest  or if such  excessive
 interest exceeds  the  unpaid balance  of  principal, the  excess  shall  be
 refunded to the Maker hereof.  All sums contracted for, charged or  received
 hereunder  for  the  use,  forbearance  of  detention  of  the  indebtedness
 evidenced hereby  shall,  to the  extent  permitted by  applicable  law,  be
 amortized, prorated, allocated and spread through the full term of this Note
 until payment in full so that  the rate of interest  on the account of  such
 indebtedness is  uniform  through the  full  term  hereof.   The  terms  and
 provision  of  this  paragraph  shall  control  and  supersede  every  other
 provision of all agreements between the undersigned and the holder hereof.

 reissuance by the issuer of  this instrument to the  new holder, or (b)  the
 issuance by the Issuer of  a new instrument to  the new holder. Transfer  of
 this instrument at any time by any means other than the method described  in
 this paragraph shall be deemed void  and ineffectual. This instrument  shall
 not be convertible to bearer form.

 ceiling under Texas law shall be the indicated rate ceiling as described  in
