cent (50%) of the net proceeds  collected by Borrower  from its ongoing  private
placement.  Such  principal  reductions  shall  be made at the  closing  of each
additional investment in such private placement.

and Lender agrees to pay a placement  agent fee to Placement Agent in accordance

borrower and Placement Agent.

to prepay the unpaid principal  balance of this Note in whole or in part without
penalty,  but with interest on the unpaid principal  balance accrued to the date
of prepayment.

              This Note shall be governed and construed in  accordance  with the
internal  laws of the  state of  Georgia  without  regard to the  principles  of
conflict of laws. Borrower consents to the jurisdiction of the Superior Court of
the State of Georgia, Fulton County and/or any Federal District Court located in
the state of Georgia for any suit brought under this Note.

              The Borrower agrees that a facsimile of this Note signed on behalf
of Borrower shall constitute an enforceable obligation against Borrower. If suit
is brought for the  collection  of this Note  Borrower  shall not be entitled to
raise as a defense  that a facsimile  of this Note and not an original  has been
placed in evidence.

              The Borrower  agrees that if, and as often as, this Note is placed
in the hands of an attorney  for  collection  or to defend or enforce any of the
Lender's  rights under this Note the Borrower  will pay the Lender's  reasonable
attorneys'  fees, all court costs and all other expenses  incurred by the Lender
in connection therewith.


       IN WITNESS WHEREOF,  the Borrower has executed this instrument  effective
