ITEM 9.  REGULATION FD DISCLOSURE.

         In conjunction  with the  Company's annual  Form 10-KSB for its  fiscal
year ended  September 30, 2002, and the Company's  quarterly Form 10-QSB for the
period ended December 31, 2002, accounts payable liabilities were presented that
included  approximately  $150,000 to its largest  creditor,  a services firm. In
late March of 2003, the Company came to a definitive  settlement  agreement with
this  creditor  regarding  this  debt.  The  result  of this  agreement  was the
elimination of approximately $150,000 of short term liability previously owed by
the  Company  to  this  creditor.  The  Company  was  able  to  eliminate  these
liabilities without the use of cash. This settlement is anticipated to result in
a  reduction  in the  Company's  net losses of  approximately  $125,000  for the
quarter ended March 31, 2003,  as well as  approximately  a $25,000  increase in
overall shareholders equity. Full operating results for that quarter are not yet
available,  but the  results of  operations  for that  quarter,  including  this
settlement,  are  expected  to be reported by the Company in its Form 10-QSB for
the period ended  March 31, 2003,  which is  expected to be  filed on or  before
May 15, 2003.
