(b)  The  Optionee  shall have the right to purchase  the shares as to which the
     options  shall become  exercisable  only while  Optionee is employed by the
     Grantor,  except if the Optionee's employment has terminated for any reason
     other than death or disability,  the options may be exercised to the extent
     that they are exercisable upon the effective date of such  termination,  at
     any time within  three (3) months after the date of  termination  but in no

     reasonable  written notice [not less than thirty (30) days unless waived in
     writing  by the  Chairman  of the  Board]  the  options  shall  immediately
     terminate.

5.    DIVISIBILITY AND NON-ASSIGNABILITY OF THE OPTIONS.

(a)  The  Optionee may  exercise  the options  herein  granted from time to time
     during the periods of their  respective  effectiveness  with respect to any

     exercisable during Optionee's lifetime only by the Optionee.

(c)  In the event of the  Optionee's  death  while  employed  by the  Grantor or

     reasonable  notice (not less than 30 days  unless  waived in writing by the
     Chairman of the Board)]  Optionee's  estate, or any person who acquired the
     right to exercise such option by bequest or inheritance or by reason of the
     death of the Optionee,  shall have the right at any time within a period of
     one (1) year after the Optionee's  death, but not after ten (10) years from
     the date  hereof,  to exercise  this option to the extent of the  following
     schedule:

     TIME FROM GRANTING OF OPTION                    PERCENTAGE EXERCISABLE

     From              To the End of

     1 day                  12 mos.                         33%
     12 mos.                24 mos.                         67%
     after 24 mos.                                         100%

(d)  In the  event  of the  Optionee's  permanent  and  total  disability  while
     employed  by the  Grantor,  the  Optionee  shall have the right at any time
     within a period of one (1) year after  cessation of Optionee's  employment,
     but not after ten (10) years from the date hereof,  to exercise this option
     to the extent of the above schedule.  For this purpose,  the Optionee shall
     be  considered  permanently  and totally  disabled if Optionee is unable to
     engage in any  substantial  gainful  activity  by  reason of any  medically
     determinable  physical or mental impairment which can be expected to result
     in death or which has lasted or can be  expected  to last for a  continuous
     period of not less than  twelve  (12)  months.  The  Optionee  shall not be
     considered permanently and totally disabled unless Optionee furnishes proof
     of the  existence  thereof  in such form and  manner and at such times as a
     committee  appointed  by the  Chairman of the Board of Grantor may require.
     The Optionee agrees that said  committee's  determination as to whether the
     Optionee is permanently  and totally  disabled shall be final and absolute,
     and not  subject to  question  by the  Optionee,  a  representative  of the
     Optionee, or the Grantor.

6.   STOCK AS INVESTMENT.  By accepting this option the Optionee  agrees for the
     Optionee,  Optionee's  heirs and legatees  that unless the shares have been
     registered under the Securities Act of 1933, as amended, any and all shares
     purchased   hereunder   shall  be  acquired  for  investment  and  not  for
     distribution,  and upon the issuance of any or all of the shares subject to
     the option granted hereunder, the Optionee, or Optionee's heirs or legatees
     receiving  such shares,  shall deliver to the Grantor a  representation  in
     writing  that such shares are being  acquired in good faith for  investment
     and not for  distribution.  Grantor may place a "stop  transfer" order with
     respect to such shares  with its  transfer  agent and place an  appropriate
     restrictive  legend  on  the  stock  certificate  unless  such  shares  are
     registered.



7.   RESTRICTION  ON  ISSUANCE OF SHARES.  The Grantor  shall not be required to
     issue or deliver any  certificate for shares of its capital stock purchased
     upon the exercise of this option:

(a)  prior to the  admission of such shares to listing on any stock  exchange on
     which  the  stock  may at that  time be  listed  and,  in the  event of the
     exercise of this option with respect to any shares of stock subject hereto,
     the Grantor shall make prompt application for such listing;

(b)  unless the prior  approval of such sale or issuance has been  obtained from
     any state regulatory body having jurisdiction; or

(c)  unless the shares with respect to which the option is being  exercised have
     been registered under the Securities Act of 1933, as amended, or are exempt
     from registration.

8.  ADJUSTMENT OF SHARES.

(a)  If additional  shares of common stock are issued by the Grantor pursuant to
     a stock  split or stock  dividend in excess of 5% in any one fiscal year of
     the  Grantor,  the number of shares of common  stock  then  covered by each
     option granted herein shall be increased  proportionately  with no increase
     in the total  purchase  price of the shares then so  covered.  In the event
     that the shares of common stock of the Grantor are reduced at any time by a
     combination of shares, the number of shares of common stock then covered by
     each  option  granted  herein  shall  be  reduced  proportionately  with no
     reduction in the total price of the shares then so covered.  If the Grantor
     shall be reorganized,  consolidated or merged with another corporation,  or
     if all or  substantially  all of the assets of the Grantor shall be sold or
     exchanged,  the Optionee  shall, at the time of issuance of the stock under
     such a corporate  event,  be entitled to receive  upon the  exercise of his
     option,  the same  number and kind of shares of stock or the same amount of
     property, cash or securities as he would have been entitled to receive upon
     the happening of any such  corporate  event as if he had been,  immediately
     prior to such  event,  the holder of the  number of shares  covered by this
     option.  No option  adjustment  shall be made for stock  dividends or stock
     splits  which are not in excess of 5% in any one fiscal  year (even  though
     the cumulated  total of such stock dividends over the life of an option may
     be in excess of 5%), cash dividends or the issuance to  stockholders of the
     Company  of  rights  to  subscribe  for  additional  common  stock or other
     securities.

(b)  Any adjustment in the number of shares shall apply  proportionately to only
     the unexercised  portion of an option granted hereunder.  If fractions of a
     share  would  result  from any such  adjustment,  the  adjustment  shall be
     revised to the next higher whole number of shares.

9.   NO RIGHTS IN OPTION STOCK.  Optionee  shall have no rights as a stockholder
     in respect of shares as to which the option  shall not have been  exercised
     and payment  made as herein  provided and shall have no rights with respect
     to such shares not herein provided.

10.  NO CONTRACT OF  EMPLOYMENT.  Optionee  further  represents,  covenants  and
     warrants this Agreement  does not constitute a contract of employment  with
     the Grantor or any of its subsidiaries or affiliates,  nor does it give the
     Optionee any right to be employed by the Grantor,  and that unless Optionee
     has a written  contract of  employment  signed by the  Grantor,  Optionee's
     employment is terminable at will by Grantor, with or without cause.

11.  BINDING  EFFECT.  Except  as  herein  otherwise  expressly  provided,  this
     Agreement  shall be binding  upon and inure to the  benefit of the  parties
     hereto, their legal representatives and assigns.

12.  JURISDICTION  OF DISPUTES.  The  appropriate  Federal or State Courts of or
     located  in the  State in which the  Grantor  has its  principal  executive
     offices shall have  exclusive  jurisdiction  of all disputes  arising under
     this Agreement.




13.  COVENANT NOT TO COMPETE AND  CANCELLATION  AND RESCISSION OF OPTIONS.  As a
     condition for acceptance of this Agreement, Optionee agrees that during the
     one (1) year period following Optionee's  termination of employment for any
     reason  (excluding any such  termination  by Grantor),  Optionee shall not,
     directly or indirectly, work for or render any services to any person, firm
     or business located within a 150 mile radius of Grantor's  Corporate office
     in  Middlebury,   Connecticut   which  offers   products   and/or  services
     competitive to the products and/or services of Grantor.  Upon  termination,
     in order to  ascertain  if  future  employment  would  be  deemed  to be in
     non-compliance with this covenant, an Optionee should notify the Grantor as
     to  Optionee's  future  employer  and make a request for approval to retain
     Optionee's  rights  under this  option on the basis of  demonstrating  that
     Optionee is not entering into a competitive situation. If a non-competitive
     situation is demonstrated to the Company's satisfaction, then such approval
     shall not be unreasonably  withheld.  In the event Optionee fails to comply
     with or otherwise  breaches this  covenant in any way, (i) all  unexercised
     options  shall  immediately  be  rescinded  and be of no  further  force or
     effect, and (ii) during the two year period following any such termination,
     Grantor  may notify  Optionee in writing of the  rescission  of any options
     exercised by Optionee  after any such  termination  and/or  within nine (9)
     months prior to any such termination of Optionee's  employment.  Within ten
     (10) days after  receiving  such a notice from Grantor,  the Optionee shall
     pay to Grantor in cash, the aggregate amount of any gain resulting from the
     exercise by Optionee of such rescinded  options and the subsequent sales of
     the shares received on such exercise or, if no such sale of said shares has
     occurred,  at Grantor's demand,  return the shares received on the exercise
     of such rescinded options against the refund by the Grantor of the exercise
     price therefor.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and
year first above written.
