The purpose of this letter agreement is to set forth the terms and conditions of
the Swap Transaction  entered into between KeyBank National  Association ("Key")
and Vicon  Industries,  Inc  ("Counterparty")  on the Trade Date specified below
(the "Swap Transaction").  This letter agreement constitutes a "Confirmation" as
referred to in the Swap Agreement Specified below.

This Confirmation  replaces that certain  Confirmation with a Notional Amount of
$2,512,000 dated December 29, 1997 between Key and Counterparty.

         1.  The  definitions   and  provisions   contained  in  the  1991  ISDA
Definitions (as published by the International Swap Dealers  Association,  Inc.)
(the "Definitions") are incorporated into this Confirmation.

              If you and we are  parties to a Master  Agreement  that sets forth
the general terms and conditions  applicable to Swap Transactions  between us (a
"Swap  Agreement"),  this  confirmation  supplements,  forms a part  of,  and is
subject to , such Swap  Agreement.  If you and we are not yet  parties to a Swap
Agreement, this Confirmation will supplement, form a part of, and be subject to,
a Swap  Agreement  upon its execution and delivery by you and us. All provisions
contained or  incorporated by reference in such Swap Agreement shall govern this
Confirmation   except  as  expressly   modified  below.  In  the  event  of  any
inconsistency  between  this  Confirmation  and  the  Definitions  or  the  Swap
Agreement,  this Confirmation will govern. In addition,  if a Swap Agreement has
not been executed,  this  Confirmation  will itself evidence a complete  binding
agreement  between  you  and us as to  the  terms  and  conditions  of the  Swap
Transaction to which this Confirmation relates.

              This  Confirmation will be governed by and construed in accordance
with the laws of the  State of New  York,  without  reference  to  choice of law
doctrine,  provided that this  provision will be superseded by any choice of law
provision in the Swap Agreement.
