$650,000.00
Bohemia, New York                                             September 17, 2001

     FOR VALUE RECEIVED,  the undersigned,  Vizacom Inc., a Delaware corporation
(the  "Maker"),  does  hereby  unconditionally  promise  to pay to the  order of
SpaceLogix,  Inc.  ("Payee"),  at the  principal  place of  business  of  Payee,
presently located at 500 Fifth Avenue, 14th Flr., New York, NY 10176, or at such
other place as the Payee or any holder hereof may from time to time designate in
writing to Maker, in lawful money of the United States and immediately available
funds,   the   principal  sum  of  SIX  HUNDRED  AND  FIFTY   THOUSAND   DOLLARS
($650,000.00),  or such lesser amount as is due hereunder,  with interest on the
unpaid balance of said  principal  amount from the date of  disbursement  to and
including  the date of repayment at the rate of nine percent (9%) per annum,  at
maturity.  Interest shall be calculated daily, on the basis of the actual number
of days elapsed in a 360 day year of twelve 30-day  months,  and  capitalized by
the addition of such accrued interest to the principal amount outstanding on the
first day of each and every month in which any obligation  under this Promissory
Note (this "Note") is outstanding. All amounts outstanding under this Note shall
mature on demand only upon  termination of  negotiations  of the merger of Payee
into Maker or one of Maker's subsidiaries (the "Merger"),  pursuant to the terms
of a merger agreement (the "Merger  Agreement") to be negotiated by the Parties,
provided  in  writing  by either  of Maker or Payee  evidencing  an  irrevocable
breakdown in negotiations,  after which demand this Note shall be payable at the
rate of FORTY THOUSAND DOLLARS  ($40,000.00)  per month,  with the first payment
due on the  one-month  anniversary  of such written  notice  being  provided and
subsequent  payments  due on each  monthly  anniversary  thereafter,  until  all
obligations outstanding under this Note have been paid in full.

     The  principal  amount of  indebtedness  evidenced  hereby  shall equal the
initial advance of $250,000.00 made by Payee to Maker on the date hereof.  Payee
shall  advance  additional  monies  pursuant  to  this  Note  as  follows:   (i)
$200,000.00  upon the  execution and delivery to Payee by Maker of a first draft
of the Merger  Agreement  that  reasonably  reflects the terms  contained in the
Letter of Intent dated September 7, 2001,  which  contemplates  the Merger,  and
(ii) $200,000.00 upon the execution and delivery of the Merger Agreement.  Maker
at its option may repay from time to time all or any  portion of the amounts due
and  owing  pursuant  to  this  Note.  It is  therefore  contemplated  that  the
outstanding  indebtedness evidenced hereby shall fluctuate accordingly but in no
event shall the maximum amount  outstanding at any one time exceed the principal
amount of this Note  plus any  capitalized  interest.  Payee is  authorized  and
directed  to  endorse on the  Schedule  to this Note the date and amount of each
advance of funds to Maker, the monthly  capitalization  of all accrued interest,
and any payments,  whether principal or interest, made by Maker under this Note,
and  such   endorsement   shall  be  prima  facie   evidence  of  such  advance,
capitalization or payment.

     1.     Events  of  Default.   Upon  the  occurrence of any of the following
events (each, an "Event of Default" and collectively, the "Events of Default"):
