                                 Clearwater, Florida

FOR  VALUE  RECEIVED,  SYSTEMS COMMUNICATIONS INC., a  Florida  corporation

assigns (hereinafter called "REGISTERED HOLDER"), the sum of _____________,
together  with interest (computed on the basis of a 365 day  year  for  the
actual  number  of  days  elapsed)  on the  outstanding  principal  balance
remaining  unpaid  from time to time until paid at ten  percent  (10%)  per
annum.   At any time next following the 365th day following the date hereof
there  would  occur  and be continuing an Event of Default  in  payment  of
principal or interest or both.  In such event, BORROWER shall upon  default
pay  to  REGISTERED HOLDER interest on the outstanding principal amount  of
this Note at the highest rate of interest allowable by law from the date of
such  Event of Default until such Event of Default shall be cured or waived
until this Note, with interest thereon, is fully paid as otherwise provided
herein.

Said  principal  and interest shall be payable at the principal  office  of
BORROWER  by hand delivery or deposit of shares of BORROWER's Common  Stock
and  BORROWER's Warrants, as provided below, in the U.S. Mail, first  class
postage  prepaid, addressed to REGISTERED HOLDER at its address  registered
on  the books of the BORROWER or at such other address as REGISTERED HOLDER
may designate from time to time.

Interest  on  the outstanding principal balance of this Note  (unless  upon
default as aforesaid) shall accrue at 10% per annum commencing on the  date
set forth above until paid as herein provided.

PRINCIPAL AND INTEREST PAID BY CONVERSION:

The number of shares of BORROWER's Common Stock by which this Note shall be
automatically  repaid  and  into  which  this  Note  shall   be   converted
automatically shall be _______ Common Shares as to principal (i.e.: $______
per  share conversion) and the interest accrual payment shall be determined
by  dividing  the  outstanding accrued interest on the effective  date  set
forth below by the average of the BID-ASK price of said shares at the close
of  trading on the first trading day next following the effective  date  of
issuing  of  the  forthcoming (1996) registration statement for  BORROWER's
Common  Stock  which  is the "EFFECTIVE DATE".  The certificates  for  such
shares of Common Stock shall be delivered as of the effective date.

The  date  of  such  repayment and automatic conversion  of  the  principal
($______)  shall  be  the effective date of BORROWER's  first  registration
statement after the date hereof pursuant to the Securities Act of 1933,  as

Notwithstanding any other provision of this Note or of any instrument with
respect  to  this Note or any other instrument executed in connection  with
the  loan  evidenced by this Note, it is expressly agreed that the  amounts
payable  under this Note or under the aforesaid instruments for the payment
of  interest  or  any  other payment in the nature of  or  which  would  be
considered  as interest or other charge for the use or loan of money  shall
not  exceed  the  highest contract rate allowable by law of  the  State  of
Florida, from time to time, and in the event the provisions of this Note or
of such other instruments referred to herein with respect to the payment of
interest or other payments in the nature of or which would be considered as
interest  or  other  charge for the use or loan of money  shall  result  in
exceeding  such limitation, then the excess over such limitation shall  not
be  payable  and  the amount otherwise agreed to have been  paid  shall  be
reduced by the excess so that such limitation will not be exceeded, and  if
any  payment actually made shall result in such limitation being  exceeded,
the  amount  of the excess shall constitute and be treated as a payment  on
the  unpaid  principal  balance hereof and shall  operate  to  reduce  such
principal  balance by the amount of such excess, or if  in  excess  of  the
principal indebtedness, such excess shall be refunded to BORROWER.

BORROWER does hereby (a) agree to no course of dealing or delay or omission
or  forbearance on the part of REGISTERED HOLDER in exercising or enforcing

Note,  notice  of  the  occurrence  of any  default  under  this  Note  and

If  a default occurs hereunder, then at the option of REGISTERED HOLDER (a)
the  entire  principal  amount then remaining unpaid and  accrued  interest
