                          FORM OF EMPLOYMENT AGREEMENT


   
         AGREEMENT  made as of the ____  day of  _______________,  1997,  by and
between SENTRY TECHNOLOGY CORPORATION, a Delaware corporation with its principal
offices   at  350   Wireless   Boulevard,   Hauppauge,   New  York   11788  (the
"Corporation"), and Andrew L. Benson (the "Executive").
    

                              W I T N E S S E T H :

         WHEREAS,  the Executive had previously  entered into a  non-competition
agreement  (the "Video  Non-Competition  Agreement")  Video  Sentry  Corporation
("Video"),  providing  for the  compensation  of the  Executive by Video for two
years subject to certain terms and conditions;

         WHEREAS,  the  parties  intend that this  Agreement  shall be deemed to
supersede the terms of the Video Non-Competition Agreement;

         NOW,  THEREFORE  in  consideration  of the mutual  covenants  contained
herein, the parties hereto agree as follows:

         1.  Term.  The  Corporation  hereby  employs  the  Executive,  and  the
Executive agrees to serve the Corporation,  upon the terms and conditions hereof
for the period commencing on the date hereof and, unless Executive's  employment
under the Agreement is otherwise  terminated in accordance  with the  provisions
hereof,  continuing through and including ___________,  199_ [TWO YEARS FROM THE
DATE OF THE CLOSING OF THE MERGER] (the "Term of  Employment").  Notwithstanding
anything to the contrary set forth in the Agreement,  the Term of Employment may
be terminated pursuant to Sections 7, 8 or 10 hereof.



         2.       Duties.

         A. The  Corporation  agrees to employ the Executive  during the Term of
Employment  as an  executive  officer  of the  Corporation,  initially  as  Vice
President,  CCTV  Products,  to have such  title and  responsibilities  with the
Corporation as the Board of Directors shall from time to time direct.

         B. The Executive  agrees that he will devote  substantially  all of his
time and attention to the affairs of the Corporation and use his best efforts to
promote the  business  and  interests  of the  Corporation  and that he will not
engage,  directly or indirectly,  in any other business or occupation during the
term of employment hereunder. It is understood, however, that the foregoing will
not prohibit the Executive from engaging in personal  investment  activities for
himself and his family which do not interfere with the performance of his duties
hereunder.

         3.       Compensation.

         A.  The  Corporation  will pay the  Executive  for all  services  to be
rendered by the Executive hereunder (including, without limitation, all services
to be rendered by him as an officer and/or  director of the  Corporation and its
subsidiaries  and  affiliates)  an annual Base Salary of an amount  equal to one
percent  (1%) of the gross  booking (as defined in Exhibit A hereto) of the CCTV
Division  up to the amount  budgeted  each year (the  "Budgeted  Amount") by the
Board of Directors (the "Base  Salary").  The Executive shall have the option to
receive an advance  against  the Base  Salary of up to  $125,000  per annum (the
"Advance"),  payable in  accordance  with the regular  payroll  practices of the
Corporation. Should the bookings of the CCTV Division exceed the Budgeted Amount
for any year during the Term of Employment,  the Executive  shall be entitled to
an additional 0.2% of the total gross sales of the Division,  in addition to the
Base  Salary.  However,  should the  bookings of the CCTV  Division for any year

                                       2



   
during the Term of  Employment  fall below the Budgeted  Amount,  the  Executive
shall return any unearned  Advance  within 30 days  following the close of books
for the applicable  calendar year. In addition,  the Corporation  shall have the
right to remove the  Executive  and appoint a new  executive as Vice  President,
CCTV  Division.  If the  Corporation  chooses to appoint a new executive as Vice
President,  CCTV Division,  the Base Salary of the Executive  shall be an amount
equal to  five-tenths  of one  percent  (0.5%)  of  the  sales  effected  by the
Executive.
    

         B. The  Corporation  may also pay the  Executive  an annual  bonus with
respect to each fiscal year of the  Corporation,  either on an "ad hoc" basis or
pursuant  to a  bonus  plan  or  arrangement  as  may  be in  effect  or  may be
established  at  the  Corporation's  discretion  for  senior  executives  of the
Corporation.  Nothing herein contained shall, however,  obligate the Corporation
to pay any bonus to the Executive, it being understood that any such bonus shall
be in the sole discretion of the Board of Directors and that the amount thereof,
if any, may vary  depending on actual  performance  of the  Corporation  and the
Executive as determined in the discretion of the Board.

         C. Nothing  contained  herein shall  prohibit the Board of Directors of
the  Corporation,  in its sole  discretion,  from  increasing  the  compensation
payable to the Executive  pursuant to this Agreement  and/or making available to
the  Executive  other  benefits in addition to those to which the  Executive  is
entitled hereunder.

   
         D. In addition to the Base Salary and any annual bonus, the Corporation
hereby agrees,  subject to approval by the Corporation's Board of Directors,  to
issue promptly to the Executive,  under the  Corporation's  1997 Stock Incentive
Plan, an option to purchase 50,000 shares of the Corporation's common stock, par
value $0.001 per share. Of the options  granted  pursuant  hereto,  25,000 shall
become  immediately  exercisable  at the end of the  first  year of the  Term of
Employment.  Should the sales of the CCTV  Division  meet or exceed the Budgeted
Amount  for the  first  year of the Term of  Employment,  the  remaining  25,000
options shall vest at the end of the
    


                                       3




second  year of the Term of  Employment.  However,  should the sales of the CCTV
Division fall below the Budgeted Amount, the remaining 25,000 options shall vest
at a rate of five percent (20%) per year for a five year period, the first 5,000
to vest at the end of the second year of the Term of Employment.

         4. Expenses.  The Executive shall be entitled to  reimbursement  by the
Corporation,  in accordance with the Corporation's policies, against appropriate
vouchers  or other  receipts  for  authorized  travel,  entertainment  and other
business  expenses  reasonably  incurred by him in the performance of his duties
hereunder.

         5. Executive Benefits.

         A. The  Executive  shall be  entitled  to  participate  in, and receive
benefits  under,  any  pension,  profit  sharing,  insurance,   hospitalization,
medical, disability, stock purchase, stock option, stock ownership,  vacation or
other employee benefit plan,  program or policy of the Corporation  which may be
in effect at any time during the course of his employment by the Corporation and
which shall be generally  available  to senior  executives  of the  Corporation,
subject to the terms of such plans,  programs or policies.  Notwithstanding  the
foregoing, the Corporation may, in its discretion,  at any time and from time to
time, change or revoke any of its employee benefits plans,  programs or policies
and  Executive  shall not be deemed,  by virtue of this  Agreement,  to have any
vested interest in any such plans, programs or policies.

         B. The Executive shall be entitled to take paid vacations in accordance
with the  customary  practices of the  Corporation,  and if in any calendar year
commencing  with the year in which this Agreement is executed,  the Executive is
unable to take his full  vacation,  such  unused  vacation  time may be  carried
forward to subsequent calendar years.

         6.  Withholding.  All payments  required to be made by the  Corporation
hereunder

                                       4



to the Executive shall be subject to the withholding of such amounts relating to
taxes and other  governmental  assessments  as the  Corporation  may  reasonably
determine it should withhold pursuant to any applicable law, rule or regulation.

         7. Death;  Disability.  Upon the death of the Executive during the term
of this Agreement,  this Agreement shall  terminate.  If during the term of this
Agreement the Executive fails because of illness or other  incapacity to perform
the  services  required to be  performed by him  hereunder  for any  consecutive
period of more than 180 days, or for shorter periods  aggregating  more than 180
days in any  consecutive  twelve-month  period (any such  illness or  incapacity
being  hereinafter  referred to as "disability"),  then the Corporation,  in its
discretion,  may at any time  thereafter  terminate this Agreement upon not less
than 10 days' written notice thereof to the Executive,  and this Agreement shall
terminate  upon the  date set  forth in said  notice  as if said  date  were the
termination date of this Agreement;  provided, however, that no such termination
shall be  effective  if prior  to the  date  when  such  notice  is  given,  the
Executive's  illness  or  incapacity  shall  have  terminated  and he  shall  be
physically  and mentally  able to perform the services  required  hereunder  and
shall have taken up and be performing such duties.

         If the  Executive's  employment  shall be  terminated  by reason of his
death or disability,  the Executive or his estate,  as the case may be, shall be
entitled to receive (i) any earned and unpaid salary accrued through the date of
termination,  (ii) a pro rata  portion of any annual  bonus which the  Executive
would  otherwise  have been  entitled  to receive  pursuant to any bonus plan or
arrangement for senior  executives of the Corporation  (such pro rata portion to
be payable at the time such annual  bonus would  otherwise  have been payable to
the Executive)  (iii) an amount per annum equal to 50% of the  Executive's  Base
Salary as in effect at  termination,  payable  monthly,  for a period of one (1)
year after such termination, and (iv) subject to the terms thereof, any benefits
which  may be due  to  the  Executive  on the  date  of  termination  under  the
provisions of any employee benefit plan, program or policy.

                                       5



         8.  Termination  for Cause.  The Corporation may at any time during the
term of this  Agreement,  by written  notice,  terminate  the  employment of the
Executive  for cause,  the cause to be specified in the notice.  For purposes of
this Agreement,  "cause" shall mean (i) any willful  misconduct of the Executive
in connection  with the  performance of any of his duties  hereunder,  including
without limitation  misappropriation of funds or property of the Corporation, or
any willful and  intentional  act having the effect of injuring the  reputation,
business or business  relationships  of the  Corporation;  (ii) willful failure,
neglect or refusal to perform the Executive's duties hereunder;  (iii) breach of
any material covenants contained in this Agreement;  or (iv) conviction (or nolo
contendere  plea) in connection  with a felony or a misdemeanor  involving moral
turpitude.  Termination  for cause  shall be  effective  upon the giving of such
notice and the Executive  shall be entitled to receive (i) any earned and unpaid
salary  accrued  through the date of  termination  and (ii) subject to the terms
thereof,  any benefits  which may be due to the Executive on such date under the
provisions of any employee benefit plan, program or policy. The Executive hereby
disclaims  any right to  receive a pro rata  portion  of any  annual  bonus with
respect to the fiscal year in which such termination occurs.

         9.  Insurance.  The Executive  agrees that the  Corporation may procure
insurance on the life of the Executive,  in such amounts as the  Corporation may
in its discretion  determine,  and with the Corporation named as the beneficiary
under the policy or policies.  The  Executive  agrees that upon request from the
Corporation  he will  submit to a physical  examination  and will  execute  such
applications  and other documents as may be required for the procurement of such
insurance.

         10. Termination Following a Change in Control.

         A. If,  during  the Term of  Employment,  a change  in  control  of the
Corporation  occurs, the Term of Employment shall be automatically  extended for
the  period  ending  one year  following  the date of such  change  in  control.
Following a change in control the  Executive  shall

                                       6



be entitled to the benefits  provided in Section 10(G) upon the  termination  of
the Executive's employment during the Term of Employment unless such termination
is (a) pursuant to Section 7 because of the Executive's death or disability, (b)
by the  Corporation  pursuant  to Section 8 for cause,  or (c) by the  Executive
other than for Good Reason.

         B. For  purposes  of this  Agreement,  a  "change  in  control"  of the
Corporation shall be deemed to have occurred if

                  1. any  "person"  (as such term is used in Sections  13(d) and
         14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
         Act")), is or becomes the "beneficial  owner" (as defined in Rule 13d-3
         under the Exchange Act),  directly or indirectly,  of securities of the
         Corporation  representing  30% or more of the combined  voting power of
         the Corporation's then outstanding securities;

                  2. during any one-year  period (not including any period prior
         to the execution of this  Agreement),  individuals who at the beginning
         of such period  constitute the Board cease for any reason to constitute
         at least a majority thereof;

                  3. the  shareholders  of the  Corporation  approve a merger or
         consolidation of the Corporation with any other corporation, other than
         a merger or  consolidation  which would result in all or  substantially
         all of the individuals and entities who were the respective  beneficial
         owners  of  the  voting  securities  of  the  Corporation   outstanding
         immediately prior thereto  continuing to beneficially own more than 80%
         of  the  combined  voting  power  of  the  voting   securities  of  the
         Corporation or such surviving entity outstanding immediately after such
         merger or consolidation in substantially  the same proportions as their
         ownership,  immediately prior to such merger or  consolidation,  of the
         voting securities of the Corporation then outstanding; or


                                        7



                  4.  the  shareholders  of the  Corporation  approve  a plan of
         complete liquidation of the Corporation or an agreement for the sale or
         disposition  by the  Corporation  of all  or  substantially  all of the
         Corporation's assets.


         C.  Vesting of Incentive  Awards.  Upon the  occurrence  of a change in
control  of the  Corporation,  any and all  stock  options,  share  appreciation
rights,  phantom stock awards and restricted stock awards theretofore granted to
the  Executive  under  the  Corporation's  stock  option  plan(s)  but not  then
presently exercisable shall thereupon become vested and immediately exercisable.

         D. Good  Reason.  The  Executive  shall be  entitled to  terminate  the
Executive's  employment for Good Reason.  For purposes of this Agreement,  "Good
Reason"  shall mean,  without  the  Executive's  express  written  consent,  the
occurrence  after a change in control of the Corporation of any of the following
circumstances  unless,  in the  case  of  paragraphs  1,  5,  6, 7 or 8 of  this
subsection,  such  circumstances  are  fully  corrected  prior  to the  Date  of
Termination specified in the Notice of Termination,  as defined in subsection E,
given in respect thereof:


                  1. the assignment to the Executive of any duties  inconsistent
         with the position with the Corporation he occupied immediately prior to
         the change in control;

                  2. a reduction by the  Corporation in the  Executive's  annual
         base salary as in effect  prior to the change in control or as the same
         may be  increased  from  time  to  time  pursuant  to  the  Executive's
         employment agreement with the Corporation or otherwise;

                  3. the  relocation of the  Corporation's  principal  executive
         offices to a location  more than one hundred miles from the location of
         such  offices  immediately  prior  to the

                                       8




         change in control of the Corporation or the Corporation's requiring the
         executive to be based anywhere other than the  Corporation's  principal
         executive  offices  except  for  required  travel on the  Corporation's
         business to an extent  substantially  consistent  with the  Executive's
         business  travel  obligations  prior to the  change in  control  of the
         Corporation;

                  4. the failure by the  Corporation to pay to the Executive any
         portion of the Executive's  regular  compensation within seven (7) days
         of the date such compensation is due;

                  5. the  failure by the  Corporation  to continue in effect any
         compensation plan in which the Executive participates immediately prior
         to the change in control of the  Corporation  which is  material to the
         Executive's  total  compensation,  or the failure by the Corporation to
         continue  the  Executive's   participation   therein  on  a  basis  not
         materially  less  favorable,  both in terms of the  amount of  benefits
         provided  and the level of the  Executive's  participation  relative to
         other participants, as existed at the time of the change in control;

                  6. the failure by the  Corporation  to continue to provide the
         Executive with benefits  substantially  similar to those enjoyed by the
         Executive  under  any of the  Corporation's  life  insurance,  medical,
         health and  accident,  or  disability  plans in which the Executive was
         participating  at the time of the change in control of the Corporation,
         the taking of any action by the  Corporation  which  would  directly or
         indirectly  materially  reduce  any of such  benefits  or  deprive  the
         Executive of any material  fringe  benefit  enjoyed by the Executive at
         the time of the change in control of the Corporation, or the failure by
         the  Corporation  to  provide  the  Executive  with the  number of paid
         vacation  days to which the Executive is entitled on the basis of years
         of service with the  Corporation in accordance  with the  Corporation's
         normal  vacation  policy in effect at the

                                       9



         time of the change in control of the Corporation;

                  7. the  failure of the  Corporation  to obtain a  satisfactory
         agreement  from any  successor  to  assume  and agree to  perform  this
         Agreement, as contemplated in Section 20 hereof; or

                  8.  any  purported  termination  by  the  Corporation  of  the
         Executive's  employment  which is not effected  pursuant to a Notice of
         Termination satisfying the requirements of subsection E of this Section
         10; for purposes of this Agreement, no such purported termination shall
         be effective.

The Executive's right to terminate the Executive's  employment  pursuant to this
Section shall not be affected by the  Executive's  incapacity due to physical or
mental  illness.  The  Executive's  continued  employment  shall not  constitute
consent to, or a waiver of rights with respect to, any circumstance constituting
Good Reason hereunder. The Executive's good faith determination of "Good Reason"
shall be conclusive and binding on the  Corporation.  In the event the Executive
terminates his employment for Good Reason, Section 11(A) of the Agreement shall,
from and  after  the Date of  Termination,  cease  to  apply to  conduct  by the
Executive.

         E. Notice of Termination.  Any purported termination of the Executive's
employment by the  Corporation  or by the  Executive  shall be  communicated  by
written Notice of
Termination  to the other  party  hereto in  accordance  with  Section 19 of the
Agreement.  "Notice of Termination" shall mean a notice which shall indicate the
specific termination provision in this Agreement relied upon and shall set forth
in reasonable detail the facts and circumstances  claimed to provide a basis for
termination of the Executive's employment under the provisions so indicated.

         F.  Date of  Termination.  "Date of  Termination"  shall  mean the date
specified in the

                                       10



 Notice of Termination.

         G.  Compensation  Upon  Termination or During  Disability.  Following a
change in control of the  Corporation,  the  Executive  shall be entitled to the
following  benefits  during a period of disability,  or upon  termination of the
Executive's  employment,  as the case  may be,  provided  that  such  period  or
termination occurs during the Term of Employment:

                  1. During any period that the  Executive  fails to perform the
         Executive's  full-time duties with the Corporation as a result of death
         or  disability,  the  Executive  shall be  compensated  as set forth in
         Section 7 of the Agreement.

                  2. If the  Executive's  employment  shall be terminated by the
         Corporation  pursuant to Section 8 for cause or by the Executive  other
         than for Good Reason,  the Executive  shall be compensated as set forth
         in  Section  8 of the  Agreement,  and the  Corporation  shall  have no
         further obligations to the Executive.

                  3. If the Executive's  employment by the Corporation  shall be
         terminated by the Executive for Good Reason or by the Corporation other
         than for Cause or death or disability,  then, subject to the provisions
         of  subsection  (iv)  hereof,  the  Executive  shall be entitled to the
         benefits provided below:

                  i) the  Corporation  shall pay to the Executive the sum of (A)
                  the  Executive's  full base salary through the end of the Term
                  of Employment (without giving effect to such termination) plus
                  (B) a bonus equal to the most recent  annual bonus paid to the
                  Executive multiplied by the number of partial weeks of service
                  served by the  Executive  during the then current bonus period
                  divided  by 52,  plus  (C) all  other  amounts  to  which  the
                  Executive  is  entitled  under  any  compensation  plan of the
                  Corporation, which sum shall be payable in

                                       11




                  accordance   with  the   usual   payroll   practices   of  the
                  Corporation;

                  ii) in lieu of shares of common  stock of the  Corporation  or
                  any  of  its  subsidiaries  ("Common  Shares")  issuable  upon
                  exercise of outstanding options  ("Options"),  if any, granted
                  to the Executive under any stock option plan maintained by the
                  Corporation or any of its  subsidiaries,  the Executive  shall
                  receive an amount in cash  equal to the  product of (1) in the
                  case of Incentive Stock Options ("ISOs") granted under Section
                  422 of the  Internal  Revenue  Code of 1986,  as amended  (the
                  "Code"),  the excess of the fair value of the Common Shares on
                  the day nearest the Date of  Termination  (which  shall be the
                  closing price of Common Shares as reported on such date on the
                  New  York  Stock  Exchange  or,  if not  then  listed  on such
                  exchange,  on a  nationally  recognized  exchange or quotation
                  system on which trading volume in Common Shares is highest or,
                  if not quoted on a  quotation  system,  the average of the bid
                  and asked  prices  for the  Common  Shares  quoted by a market
                  maker in the  Common  Shares  or, if no market is then made in

                  Board of Directors of the Corporation) and, in the case of all
                  other Options, the higher of such closing price or the highest
                  per share price for Common Shares  actually paid in connection
                  with any change in control  of the  Corporation,  over the per
                  share  option  price  of each  Option  held  by the  Executive
                  (whether or not then fully exercisable), and (2) the number of
                  Common Shares covered by each such Option. Notwithstanding the
                  foregoing, the Executive shall not be entitled to cash in lieu
                  of option shares if the transaction resulting in the change of
                  control was approved by a majority of the Continuing Directors
                  (as such term is defined in the  Certificate of  Incorporation
                  of the Corporation).

                  iii) the Corporation also shall pay to the Executive all legal
                  fees and

                                       12



                  expenses  incurred  by  the  Executive  as a  result  of  such
                  termination  (including  all such fees and  expenses,  if any,
                  incurred in contesting or disputing any such termination or in
                  seeking to obtain or enforce any right or benefit  provided by
                  this Agreement); and

                  iv) the  Corporation  shall  arrange to provide the  Executive
                  through  the  end  of  the  Term  of  Employment   with  life,
                  disability,  accident  and  group  health  insurance  benefits
                  substantially   similar  to  those  which  the  Executive  was
                  receiving  immediately  prior to the  Notice  of  Termination.
                  Insurance  benefits  otherwise  receivable  by  the  Executive
                  pursuant to this paragraph (iv) shall be reduced to the extent
                  comparable  benefits  are actually  received by the  Executive
                  from a new employer,  and any such benefits  actually received
                  by the Executive shall be reported to the Corporation.

                  4.  Except as  provided in Section  10(G)(3)(iv)  hereof,  the
         Executive  shall not be required to mitigate  the amount of any payment
         provided  for  in  this  Section  10 by  seeking  other  employment  or
         otherwise,  nor shall the amount of any payment or benefit provided for
         in  this  Section  10 be  reduced  by any  compensation  earned  by the
         Executive  as  the  result  of  employment  by  another  employer,   by
         retirement benefits, by offset against any amount claimed to be owed by
         the Executive to the Corporation or otherwise.


         H.  Successors;  Binding  Agreement.  The Corporation  will require any
successor  (whether direct or indirect,  by purchase,  merger,  consolidation or
otherwise)  to all or  substantially  all of the business  and/or  assets of the
Corporation to expressly  assume and agree to perform this Agreement in the same
manner and to the same extent that the Corporation  would be required to perform
it if no such  succession had taken place.  Failure of the Corporation to obtain
such assumption and agreement prior to the  effectiveness of any such

                                       13




succession  shall be a breach of this  Agreement and shall entitle the Executive
to compensation from the Corporation in the same amount and on the same terms to
which the Executive would be entitled hereunder if the Executive  terminated the
Executive's  employment  for Good  Reason  following  a change in control of the
Corporation. As used in this Agreement, "Corporation" shall mean the Corporation
as  hereinbefore  defined and any  successor  to its business  and/or  assets as
aforesaid  which  assumes and agrees to perform  this  Agreement by operation of
law, or otherwise.

         I.  Termination  of  Executive's  Rights  Following  Change of Control.
Notwithstanding  the  foregoing,  in the  event  the  Executive  shall  not have
exercised any of the  particular  rights granted to him purusuant to paragraph D
of the  Section 10 upon the  occurrence  of a change in control  within one year
after the occurrence thereof,  then such rights of the Executive under paragraph
D shall terminated with respect to such change of control.

         11.      Non-Competition; Solicitation.

         A. The Executive agrees that during his employment with the Corporation
and for a period of two years after Executive  leaves the  Corporation's  employ
for any reason,  he shall not,  without the written consent of the  Corporation,
directly or indirectly,  either individually or as an employee,  agent, partner,
shareholder,  consultant,  option holder,  lender of money,  guarantor or in any
other  capacity,  participate  in,  engage in or have a  financial  interest  or
management  position or other  interest in any business,  firm,  corporation  or
other entity if it competes  directly with any business  operation  conducted by
the  Corporation  or its  subsidiaries  or affiliates or any successor or assign
thereof,  nor will he solicit any other person to engage in any of the foregoing
activities. Participation in the management of any business operation other than
in connection  with the  management of a business  operation  which is in direct
competition  with the  Corporation  or its  subsidiaries  or  affiliates  or any
successor or assign  thereof  shall not be deemed to be a breach of this Section
11(A). The foregoing provisions of

                                       14





this Section  11(A) shall not prohibit the  ownership by the  Executive  (as the
result of open market purchase) of 1% or less of any class of capital stock of a
corporation  which is regularly traded on a national  securities  exchange or on
the NASDAQ System.

         B. The Executive  will not at any time during his  employment  with the
Corporation  and  for  a  period  of  two  years  after  Executive   leaves  the
Corporation's  employ  for any  reason,  solicit  (or  assist or  encourage  the
solicitation  of) any employee of the Corporation or any of its  subsidiaries or
affiliates to work for Executive or for any business, firm, corporation or other
entity in which the Executive, directly or indirectly, in any capacity described
in Section 11(A) hereof,  participates  or engages (or expects to participate or
engage) or has (or expects to have) a financial interest or management position.

         C. If any of the  covenants  contained  in this  Section 11 or any part
thereof,  is held by a  court  of  competent  jurisdiction  to be  unenforceable
because  of the  duration  of such  provision,  the  activity  limited by or the
subject of such provision and/or the area covered thereby, then the court making
such  determination  shall  construe  such  restriction  so as to  thereafter be
limited or reduced to be  enforceable  to the  greatest  extent  permissible  by
applicable law.

         12.  Inventions,  Etc. The  Executive  agrees that any and all systems,
work-in-progress,  inventions, discoveries,  improvements, processes, compounds,
formulae, patents,  copyrights and trademarks,  made, discovered or developed by
him,  solely or  jointly  with  others,  or  otherwise,  during  the term of his
employment  by the  Corporation,  and  which  may be  useful in or relate to any
business  of  the  Corporation   and/or  any  subsidiary  or  affiliate  of  the
Corporation  shall be fully disclosed by the Executive to the  Corporation,  and
shall be the sole and absolute property of the Corporation. The Executive agrees
that at all times,  both during his employment and after the  termination of his
employment,  he will  keep all of the  same  secret  from  everyone  except  the
Corporation and its duly  authorized  employees and will disclose the

                                       15




same to no one except as required in good faith in the course of his  employment
with  the  Corporation,  or by  law,  or  unless  otherwise  authorized  by  the
Corporation.

         13. Patents.  The Executive  agrees, at the request of the Corporation,
to make  application  in due form for United States  Letters  Patent and foreign
Letters Patent on any of such systems,  inventions,  discoveries,  improvements,
processes,  compounds  and  formulae  referred  to in Section 12 hereof,  and to
assign to the  Corporation  all of his right,  title and interest in and to said
inventions, discoveries, improvements, processes, compounds, formulae and patent
applications  therefor or patents  thereon,  and to execute at any and all times
any and all  instruments,  and to do any and all acts which the Corporation with
the advice of counsel may deem necessary or desirable,  in connection  with such
applications  for  Letters  Patent,  in order to  establish  and  perfect in the
Corporation  the  entire  right,  title  and  interest  in and to said  systems,
inventions, discoveries, improvements, processes, compounds, formulae and patent
applications  therefor,  or in the conduct of any  proceedings  or litigation in
regard  thereto.  It is  understood  and  agreed  that all costs  and  expenses,
including but not limited to reasonable attorneys' fees, incurred at the request
of the Corporation in connection with any action taken by an Executive  pursuant
to this Section 13, shall be borne by the Corporation.

         14. Trade Secrets,  Etc. The Executive agrees that he shall not, during
or after the termination of this Agreement,  divulge, furnish or make accessible
to any person,  firm,  corporation or other business  entity,  any  information,
trade  secrets,  technical data or know-how  relating to the business,  business
practices,  methods, products,  processes,  equipment,  clients' prices or other
confidential  or secret  aspect of the  business of the  Corporation  and/or any
subsidiary or  affiliate,  except as may be required in good faith in the course
of his  employment  with the  Corporation  or by law,  without the prior written
consent  of  the  Corporation,  unless  such  information  shall  become  public
knowledge (other than by reason of Executive's breach of the provisions hereof).

                                       16




         15. Acceptance by Executive. The Executive accepts all of the terms and
provisions  of this  Agreement and agrees to perform all of the covenants on his
part to be performed hereunder.

         16. Equitable  Remedies.  The Executive  acknowledges  that he has been
employed  for his  unique  talents  and  that  his  leaving  the  employ  of the
Corporation  would seriously hamper the business of the Corporation and that the
Corporation will suffer irreparable damage if any provisions of Sections 11, 12,
13 or 14 hereof are not performed strictly in accordance with their terms or are
otherwise  breached.  The Executive hereby expressly agrees that the Corporation
shall be entitled as a matter of right to injunctive or other equitable  relief,
in  addition  to all other  remedies  permitted  by law,  to prevent a breach or
violation  by the  Executive  and to secure  enforcement  of the  provisions  of
Sections  11, 12, 13 or 14 hereof.  Resort to such  equitable  relief,  however,
shall  not  constitute  a waiver  of any  other  rights  or  remedies  which the
Corporation may have.

         17. Entire Agreement.  This Agreement  constitutes the entire agreement
between  the  parties  hereto  and there are no other  terms  other  than  those
contained  herein.  No  amendment  hereof  shall be valid  unless in writing and
signed by the parties hereto and no discharge of the terms hereof shall be valid
unless by full  performance  of the parties hereto or by a writing signed by the
parties  hereto.  No waiver by the Corporation of any breach by the Executive of
any  provision or condition  of this  Agreement by him to be performed  shall be
deemed a waiver of a breach of a similar or dissimilar provision or condition at
the same time or any prior or subsequent time.

       18.  Severability.  In case any  provision in this  Agreement  shall be
declared   invalid,   illegal  or   unenforceable  by  any  court  of  competent
jurisdiction,  the validity and enforceability of the remaining provisions shall
not in any way be affected or impaired thereby.

                                       17




         19. Notices.  All notices,  requests,  demands and other communications

address of telecopy  number as such party may hereafter  specify for the purpose
by notice to the other party and shall be either delivered personally or sent by

and  neither of the  parties  hereto  shall,  without  the consent of the other,
assign or transfer this Agreement or any rights or obligations hereunder (except
for an assignment or transfer by the  Corporation to a successor as contemplated
by the following proviso);  provided,  however, that the provisions hereof shall
inure to the benefit of, and be binding upon, any successor of the  Corporation,
whether by merger,  consolidation,  transfer of all or substantially  all of the
assets of the  Corporation,  or otherwise,  and upon the  Executive,  his heirs,
executors, administrators and legal representatives.

         21.  Governing Law. This Agreement and its validity,  construction  and
performance  shall be governed in all respects by the internal laws of the State
of New York without giving effect to any principles of conflict of laws.

                                       18




         22.  Headings.  The headings in this  Agreement are for  convenience of
