amend and rescind  rules and  regulations  for carrying out the  provisions  and
purposes  of the Plan.  All awards of options by the  Committee  are  subject to
approval  by the  Board  of  Directors.  the  interpretation,  construction  and

the Plan and such other terms and  conditions as the  Committee  may  prescribe,
grant to any  participant  in the Plan one or more stock  options  (intended  to
qualify as incentive  stock options  under the  provisions of section 422 of the
Internal  Revenue Code of 1986,  as amended (the "Code") to purchase for cash or
shares the number of shares of Common Stock allotted by the Committee.  The date
an option is granted shall mean the dated  selected by the Committee as of which

the Plan.

        6.  Changes to Capital Structure

        In the event that the outstanding  shares of common stock of the Company
are  hereafter  increased  or  decreased  or  changed  into or  exchanged  for a
different  number or kind of shares or other  securities  of the  Company  or of
another  corporation,  by  reason  or  reorganization,   merger,  consolidation,
recapitalization,  reclassification,  stock split-up,  combination of shares, or
dividend payable in capital stock,  appropriate  adjustment shall be made by the
Board of  Directors  in the  number  and kind of shares as to which  outstanding
options,  or portions thereof then unexercised,  shall be exercisable to the end
that the  optionee's  proportionate  interest  shall be maintained as before the
occurrence of such events;  such adjustment in outstanding options shall be made
without change in the total price  applicable to the unexercised  portion of the
option  and with a  corresponding  adjustment  of the  option  price per  share;
provided,  however,  that each such  adjustment in the number and kind of shares
subject to  outstanding  options,  including any adjustment in the option price,
shall be made in such manner as not to constitute a "modification" as defined in
Section  424 of the Code.  Any such  adjustment  made by the Board of  Directors
shall be conclusive.

7.      Terms and Conditions of Options

        The grant of an option shall be evidenced by a written  Incentive  Stock
Option  Agreement,  executed  by the  Company  and the holder of an option  (the
"optionee"),  stating the number of shares of Common Stock subject to the option
evidenced  thereby,  and in such  form as the  Committee  may from  time to time
determine.

     a) Option Price - The option  price per share of Common  Stock  deliverable
upon the exercise of an option shall be 100% of the fair market value of a share
of Common Stock on the date the option is granted;  however,  an optionee who is
the record and  beneficial  owner of more than 10% of the  Company's  issued and
outstanding  common stock shall be awarded options at a price equivalent to 110%
of the fair market value at the date of grant.

     b) Method of Exercise - Stock  purchased  under the options  shall,  at the
time of purchase,  be paid for in full. To the extent that the right to purchase
shares has accrued  thereunder,  options may be  exercised  from time to time by



written notice by the optionee to the Company  stating the number of shares with
respect to which the  option is being  exercised,  and the time of the  delivery
thereof,  which time  shall be at least 15 days after the giving of such  notice
unless an  earlier  date  shall  have been  mutually  agreed  upon.  At the time
specified in such notice,  the Company shall deliver,  without transfer or issue
tax to the optionee (or other  person  entitled to exercise the option),  at the
main  office  of the  Company,  or  such  other  places  as  shall  be  mutually
acceptable,  a certificate or certificates for such shares or reacquired  shares
of its Common  Stock,  as the Company may elect,  against  payment of the option
price in full for the number of shares to be delivered by (i) certified check or
the equivalent  thereof  acceptable to the Company;  or (ii) the delivery to the
Company of issued and outstanding  Common Stock of Vicon Industries,  Inc. which
has been owned by the  optionee  for at least six month,  the total fair  market
value of which on such  delivery  date is equal to the total  exercise  price of
options being exercised;  provided,  however, that the time of such delivery may
be  postponed  by the Company  for such  period as may be  required  for it with
reasonable  diligence to comply with any applicable listing  requirements of any
national  securities  exchange,  if the stock is so listed.  If the optionee (or
other person  entitled to exercise the option)  fails to accept  delivery of and
pay for all or any part of the number of shares  specified  in such  notice upon
termination of delivery  thereof,  his right to exercise the option with respect
to such  undelivered  shares may be  terminated  by the Option  Committee of the
Board of Directors without any formal notice to the optionee. Anything herein to
the contrary notwithstanding, if any law or any regulation of the Securities and
Exchange  Commission or of any other body having  jurisdiction shall require the
Company  or a  participant  to take any  action in  connection  with the  shares
specified  in a notice of election  before such shares can be  delivered to such
participant,  then the date stated  therein for the delivery of the shares shall
be postponed  until the fifth business day next following the completion of such
action.

c) Option Term - No option will be exercisable prior to the date of
shareholder approval of the plan, or any time after expiration of six years from
the date the option is granted (the "Grant Date").

d) Maximum  Amount of Incentive  Stock Option Grant - The aggregate  fair market
value  (determined on the date the option is granted) of Common Stock subject to
an incentive  stock option granted to an optionee  (pursuant to any plan) by the
Committee  and  exercisable  for the first time in any  calendar  year shall not
exceed $100,000.

e)  Exercise  of Options - As to any  option  issued  under the Plan:  it may be
exercised  up to 30% of the total  number of shares  covered  thereby  after two
years from the date of grant, it may be exercised up to an additional 30% of the
total number of shares covered thereby after three years from date of grant; and
the remaining 40% after four years from the date of grant,  and thereafter,  the
option may be exercised at any time from time to time within its terms, in whole
or in part,  but it shall not be  exercisable  after the expiration of six years
from the Grant Date.  Notwithstanding  the foregoing,  all options granted under
this Plan may be exercised in the entirety should a "Change in Control" occur. A
"Change in Control"  shall be deemed to have  occurred  if



(i) any other  entity  shall  directly or  indirectly  acquire a beneficial
ownership  of 20%,  or any further  amount in excess of 20%, of the  outstanding
shares of capital  stock of the Company or (ii) a majority of the members of the
Board of Directors of the Company or any  successor or merger or  assignment  of
assets or otherwise, shall be persons other than Directors on the date this Plan
became effective (April 22, 1999).

        f)  Non-Assignability of Option Rights - No option shall be assignable
or transferable by the optionee except by will or the by  laws or  descent  and
distribution.  During the life of an optionee,  the option shall be  exercisable
only the optionee.

        g)  Effect  of  Termination  of  Employment  or Death - In the  event an
optionee  ceases to be an  employee  of the  Company  for any reason  other than
retirement or death,  any exercisable  portion of any option as of the date such
optionee  ceased to perform  services to the Company  must be  exercised  within
three months after the date on which the optionee ceases to perform services. In
the event of the retirement of an optionee,  any option or  unexercised  portion
thereof  granted to him shall be  exercisable  within not more than three months
from the date on which  the  optionee  retires.  In the event of the death of an
optionee while such optionee is an employee of the Company, or any subsidiary of
the Company, or within three months from the date of such optionee's retirement,
the  option or  unexercised  portion  thereof  granted to such  optionee  may be
exercised by such optionee's personal  representative,  or a person who acquired
the right to exercise such option by bequest or inheritance at any time prior to
the expiration of one year from the date of death of the optionee. The foregoing
provisions  with respect to  retirement  or death of any optionee  shall,  in no
event,  be deemed to extend the date of  expiration  of the term provided in any
option held by any such optionee.

        h)  Restriction on Issuance of Shares - On the date stated in the notice
of election for the payment and delivery of the shares specified in such notice,
the  participant  shall  certify to the Company in such form as it shall require
that such  participant  will receive and hold such shares for investment and not
with a view to resale or distribution thereof to the public, unless the issuance
of such shares shall have been  registered  under the Securities Act of 1933, as
amended, and the Rules and Regulations promulgated thereunder, or counsel to the
Company  shall  have  advised  the  Company  that  for  any  other  reason  such
certification is unnecessary.

        i)  Rights as a Stockholder -  The optionee shall have no rights as a
Stockholder  with respect to any shares covered by such optionee's  option until
the date of issuance of a stock certificate to such optionee for such shares. No
adjustment shall be made for dividends or other rights for which the record date
is prior to the date such stock certificate is issued.

        j)  Successive Options - Options may be exercised in any order.




        k)  Termination of Options Upon Consent - The Option Committee may
terminate any outstanding option with the consent of the holder thereof.

     8.  Effective Date and Term of Plan

     a) The Plan,  which was adopted by the Board of  Directors  on December 10,
1998, is subject to the condition that the  Stockholders  approve the Plan prior

directors are owned  directly or indirectly  by Vicon  Industries,  Inc., or any
subsidiary thereof.

             c) "fair market value" as of any date and in respect of any share
of Common Stock means the closing  price on such date or on the next business
day, if such date is not a  business  day,  of a  share  of  Common  Stock
reflected in the consolidated trading tables of The Wall Street Journal
(presently the AMEX-Composite Transactions) or any other publication selected by
the Committee, provided  that, if shares of Common Stock shall not have been
traded on the American Stock Exchange for more than 10 days immediately
preceding such date or if deemed  appropriate by the Committee for any other
reason,  the fair market value of shares of Common Stock shall be as  determined
by the Committee in such other manner as it may deem appropriate. In no event
shall the fair market value of any share of Common Stock be less than its par
value.

        10.    Amendment of Plan

        The Board of  Directors  may at any time amend the Plan,  provided  that
without  approval of  Stockholders  there shall be,  except by  operation of the

covered by the Plan;  there shall be no change in the class of persons  eligible
to  receive  options  granted  under the Plan;  there  shall be no change in the
limitations  on the option price;  and there shall be no extension of the latest
date upon which options may be exercised. Neither the Board of Directors nor the
Stockholders   by  amendment  to  this  Plan  can  affect  options  granted  and
outstanding   under  any  prior  stock   option  plan  of  the  Company  or  its
subsidiaries.



     11. Use of Proceeds

     The proceeds from the sale of stock  pursuant to options  granted under the
Plan shall constitute general funds of the Company.

accordance with the laws of the State of New York.

     13. Liquidation

     Upon the complete  liquidation  of the  Company,  any  unexercised  options
heretofore granted under this Plan shall be deemed canceled. In the event of the
complete  liquidation  of any  employer  corporation  (other  than the  Company)
employing the participant or in event such corporation  ceases to be an employer
corporation,  any  unexercised  part of any option  granted  hereunder  shall be
deemed canceled unless the participant shall become employed by another employer
corporation (including the Company) concurrently with such event.
