This Amendment to the Client Advisory  Agreement and Trading  Authorization,  is
made and  entered  into  this 21st day of  September  by and  between  Hanseatic
Corporation,  a New  Mexico  corporation  (the  "Advisor")  and Pool  Management
Services,  Inc.,  formerly  known as The Day  Traders  Club,  Inc.,  an Oklahoma
corporation ("Client").

 WHERAS,  the Client and Advisor desire to amend certain the terms of Addendum A
of the Client Advisory Agreement And Trading  Authorization  entered into by the
parties and executed on December 14, 1998;

NOW  THEREFORE,  in  consideration  of the  premises set forth above the parties
agree to the following:

a.       As executed on December 14, 1998, Paragraph two of Addendum A of the
         Advisory Agreement and Trading Authorization states:

         "The Advisor will charge Client a monthly incentive fee equal to 10% of
         the Account's Trading Profits.  The Incentive Fee shall be payable only
         on  cumulative  profits in the  Account.  If the Account  incurs a loss
         after the  Advisor has been paid an  incentive  fee,  the Advisor  will
         retain the fee,  but will  receive no further  incentive  fee until the
         Account again achieves net new Trading Profits."

         Paragraph two of Addendum A is hereby amended to read as follows:

         "The Advisor will charge Client a quarterly  incentive fee equal to 10%
         of the Account's  Trading  Profits.  "Quarterly" is hereby defined as a
         calendar quarter consisting of three calendar months. The Incentive Fee
         shall be payable  only on  cumulative  profits in the  Account.  If the
         Account incurs a loss after the Advisor has been paid an incentive fee,
         the Advisor will retain the fee, but will receive no further  incentive
         fee until the Account again achieves net new Trading Profits."

b.       All  other  references  made to  "monthly"  incentive  fees made in the
         Client  Advisory  Agreement And Trading  Authorization  shall hereby be
         amended to read "quarterly" incentive fees.

c.       This  amendment  to Addendum A of the Client  Advisory  Agreement  And
         Trading  Authorization  is hereby  deemed  effective on
         October 1, 2001.

IN WITNESS  WHEREOF,  the parties  hereto have executed this Amendment as of the
day and year first mentioned above.
