EXHIBIT 4.1

                         MANCHESTER EQUIPMENT CO., INC.
                              AMENDED AND RESTATED
                        1996 INCENTIVE AND NON-INCENTIVE
                                STOCK OPTION PLAN


1.       Purpose of Plan.

         The  purpose  of  this  Amended  and  Restated   1996   Incentive   and
Non-Incentive   Stock  Option  Plan  ("Plan")  is  to  further  the  growth  and
development  of Manchester  Equipment Co., Inc.  ("Company")  and any direct and
indirect subsidiaries thereof (collectively,  "Subsidiaries" and each, singly, a
"Subsidiary") by encouraging selected employees, directors and other persons who
contribute and are expected to contribute materially to the Company's success to
obtain a  proprietary  interest in the Company  through the  ownership of stock,
thereby  providing  such  persons  with an added  incentive  to promote the best
interests of the Company and  affording the Company a means of attracting to its
service persons of outstanding ability.

2.       Stock Subject to this Plan.

         An aggregate of 1,100,000  shares of the Company's  Common  Stock,  par
value $.01 per share ("Common Stock"), subject, however, to adjustment or change
pursuant to Article 10 hereof,  shall be reserved for issuance upon the exercise
of options which may be granted from time to time in  accordance  with this Plan
("Options").  Such shares may be, in whole or in part,  authorized  but unissued
shares or issued shares which have been  reacquired by the Company.  If, for any
reason, an Option shall lapse, expire or terminate without having been exercised
in full, the  unpurchased  shares  covered  thereby shall again be available for
purposes of this Plan.

3.       Administration.

          (a)  The Board of Directors of the Company shall have and may exercise
               any and all of the powers relating to the  administration of this
               Plan and the grant of Options hereunder as are set forth herein.







          (b)  The  Board  shall  administer  this  Plan  and,  subject  to  the
               provisions  of  this  Plan,  shall  have  sole  authority  in its
               discretion  to  determine  the  persons to whom,  and the time or
               times at which, Options shall be granted, the number of shares to
               be subject to each such  Option and whether all or any portion of
               such  Options  shall  be  incentive  stock  options   ("Incentive
               Options")  qualifying  under Section 422 of the Internal  Revenue
               Code of 1986, as amended ("Code"),  or stock options which do not
               so qualify ("Non-Incentive  Options"). Both Incentive Options and
               Non-Incentive  Options  may be granted to the same  person at the
               same time provided each type of Option is clearly designated.  In
               making such  determinations,  the Board may take into account the
               nature of the services  rendered by such  persons,  their present
               and potential  contributions  to the  Company's  success and such
               other  factors  as the  Board  in its  sole  discretion  may deem
               relevant.  Subject to the express  provisions  of this Plan,  the
               Board shall also have the  authority to interpret  this Plan,  to
               prescribe,  amend  and  rescind  rules and  regulations  relating
               thereto,  to determine the terms and provisions of the respective
               Option Agreements,  which shall be, subject to the rights granted
               to the  Company  and the Board  hereunder,  substantially  in the
               forms  attached  hereto  as  Exhibit A and  Exhibit  B, with such
               changes  thereto as may be  necessary  to  reflect  the terms and
               conditions  of the  grant  in  question,  and to make  all  other
               determinations  necessary or advisable for the  administration of
               this Plan,  all of which  determinations  shall be conclusive and
               not subject to review.

4.       Eligibility for Receipt of Options.

          (a)  Incentive Options.

               Incentive  Options may be granted  only to  employees  (including
               officers) of the Company and/or any of its Subsidiaries.

               The aggregate  Fair Market Value (as defined in Article 5 of this
               Plan), determined as of the time the Incentive Option is granted,
               of the shares of the Company's Common Stock purchasable hereunder
               exercisable for the first time by an employee during any calendar
               year may not exceed $100,000.

               A  director  of  the  Company  or  any  Subsidiary  who is not an
               employee  of the  Company  or of one of its  Subsidiaries  is not
               eligible to receive Incentive  Options under this Plan.  Further,
               Incentive  Options  may not be granted to any person  who, at the
               time the Incentive  Option is granted,  owns (or is considered as
               owning  within the  meaning of Section  424(d) of the Code) stock
               possessing  more than 10% of the total combined  voting powers of
               all  classes of stock of the  Company or any  Subsidiary  (a "10%
               Owner"),  unless at the time the Incentive Option is granted to a
               10% Owner,  the option  price is at least 110% of the fair market
               value of the Common  Stock  subject  thereto  and such  Incentive
               Option by its terms is not  exercisable  subsequent to five years
               from the date of grant.

           (b) Non-Incentive Options.

               Non-Incentive  Options may be granted to any employees (including
               employees who have been granted  Incentive  Options),  directors,
               consultants,  agents,  independent  contractors and other persons
               whom  the  Board  determines  will  contribute  to the  Company's
               success.

          (c)  Notwithstanding  the forgoing,  the maximum  aggregate  number of
               shares  with  respect  to which  Options,  whether  Incentive  or
               Non-Incentive,  may be granted to any  person  eligible  therefor
               under this Plan within any one calendar year is 200,000 shares.







5.       Option Price.

         The  purchase  price of the shares of Common  Stock  under each  Option
shall be determined by the Board,  which  determination  shall be conclusive and
not subject to review,  but in no event shall such  purchase  price be less than
(i) 100% of the fair  market  value of the Common  Stock on the date of grant of
Incentive  Options (110% of the fair market value of Common Stock on the date of
grant where the grant of Incentive Options is made to a 10% Owner), and (ii) 85%
of the  fair  market  value  of the  Common  Stock  on the  date  of  grant  for
Non-Incentive Options.

         In  determining  the  fair  market  value of the  Common  Stock as of a
specified date ("Fair Market Value"),  the Board shall  consider,  if the Common
Stock is: (a)  publicly  traded and  listed on the New York  Stock  Exchange  or
another  national  securities  exchange or The Nasdaq Stock Market,  the closing
sale price of the Common  Stock on the business day  immediately  preceding  the
date as of which  the Fair  Market  Value  is being  determined,  or on the next
preceding  date on which  such  Common  Stock is traded  if no Common  Stock was
traded on such  immediately  preceding  business day, or, if the Common Stock is
not so listed on a national  securities exchange or The Nasdaq Stock Market, but
publicly traded, the representative  closing sale price in the  over-the-counter
market as quoted by the National  Quotation Bureau or a recognized dealer in the
Common Stock,  on the date  immediately  preceding the date as of which the Fair
Market Value is being  determined,  or on the next  preceding date on which such
Common  Stock is  traded  if no Common  Stock  was  traded  on such  immediately
preceding  business  day; or (b) not publicly  traded,  the fair market value as
determined  by the Board in good  faith  based on such  factors as it shall deem
appropriate.  The Board may also  consider  such other  factors as it shall deem
appropriate.

         For purposes of this Plan,  the date of grant of an Option shall be the
date on which the Board shall by resolution duly authorize such Option.

6.       Term of Options; Termination.

          (a)  The  term of each  Option  shall be such  number  of years as the
               Board shall determine, subject to earlier termination as provided
               herein and in the Option  Agreement  (and each  Incentive  Option
               being  subject to the  limitations  set forth in Section  4(a) of
               this Plan with respect to grants to 10% Owners),  but in no event
               shall the term of any Option be more than ten years from the date
               of  grant.  No  Option  may be  exercised  following  termination
               thereof.

          (b)  If an Incentive Option holder's  employment with the Company or a
               Subsidiary is  terminated  for any reason other than by reason of
               death or  disability  (within the meaning of Section  22(e)(3) of
               the Code), such holder's  Incentive Option shall terminate on the
               earlier of (i) three (3) months from the date of such termination
               of employment,  or (ii) the  expiration  date of the term of such
               Option.  Absence on leave  approved by the  employer  corporation
               shall not be considered  an  interruption  of employment  for any
               purpose under this Plan.







          (c)  If an Incentive Option holder's  employment with the Company or a
               Subsidiary is  terminated  by reason of such holder's  disability
               within the meaning of Section  22(e)(3)  of the Code,  subject to
               paragraph  6(d)  hereof,  such  holder's  Incentive  Option shall
               terminate  on the  earlier  of (i) one (1) year  from the date of
               such termination, or (ii) the expiration date of the term of such
               Option.

          (d)  If an  Incentive  Option  holder  dies while in the employ of the
               Company  or a  Subsidiary  (or  within  one  (1)  year  following
               termination of employment due to disability within the meaning of
               Section  22(e)(3) of the Code),  such holder's  Incentive  Option
               shall  terminate on the earlier of (i) one (1) year from the date
               of death,  or (ii) the expiration date of the term of the Option.
               To the  extent  such  Incentive  Option was  exercisable  by such
               holder  at the  date of  death  (or the  date of  termination  of
               employment  due to  disability  within  the  meaning  of  Section
               22(e)(3)  of the  Code),  such  Option  may be  exercised  by the
               legatee or legatees of such person under such person's Last Will,
               or by such  person's  personal  representative  or  distributees,
               within  one (1)  year  from  the  date of  death  but in no event
               subsequent to the expiration date of the Incentive Option.

7.       Exercise of Options.

          (a)  Incentive and Non-Incentive  Options shall be exercisable  within
               the times or upon the events determined by the Board as set forth
               in the Option Agreements.

          (b)  An  Option  may not be  exercised  for  fractional  shares of the
               Company's Common Stock.

          (c)  If  an  Option  holder  ceases  to  be  an  employee,   director,
               consultant,   agent,   independent  contractor  or  other  person
               employed  by or engaged in  performing  services  for the Company
               and/or a  Subsidiary,  the Option  held by such  person  shall be
               exercisable  after  the  date of  termination  of  employment  or
               engagement only to the extent such Option was exercisable by such
               holder at the date of termination.  In no event shall such option
               be  exercisable  following the  expiration of its term or earlier
               termination.







          (d)  The exercise of an Option shall be contingent upon receipt by the
               Company   from  the   holder   of  such   Option   of  a  written
               representation  that  at the  time  of  such  exercise  it is the
               Optionholder's  then  present  intention  to  acquire  the Option
               shares for investment and not with a view to the  distribution or
               resale  thereof  (unless a  Registration  Statement  covering the
               shares  purchasable  upon exercise of the Options shall have been
               declared effective by the Securities and Exchange Commission) and
               upon receipt by the Company of cash, or a check to its order, for
               the full purchase price of such shares.  In addition,  the holder
               of such Option must agree to refrain  from selling or offering to
               sell any securities of the Company for such reasonable  period of
               time  after  the  effective  date of any  registration  statement
               relating  to  an  underwritten  offering  of  securities  of  the
               Company, as may be requested by the managing  underwriter of such
               underwritten  offering,  and approved by the Board of  Directors.
               The Company  shall be under no  obligation to register the Shares
               with  the  Securities  and  Exchange   Commission  or  to  effect
               compliance   with  the   Securities  Act  of  1933  or  with  the
               registration or qualification requirement of any state securities
               laws or stock exchange.

          (e)  Payment for the shares of Common Stock may be made (i) in cash or
               by check to the order of the Company; (ii) by surrender of shares
               of Common  Stock having a Fair Market Value equal to the exercise
               price of the Option; or (iii) by any combination of the foregoing
               where  approved  by the Board in its sole  discretion;  provided,
               however,  in the event of payment for the shares of Common  Stock
               by method (ii) above,  the shares of Common Stock so surrendered,
               if  originally  issued to the  Optionholder  upon  exercise of an
               Option(s)  granted  by the  Company,  shall have been held by the
               Optionholder for more than six months.

          (f)  The  holder  of an  Option  shall  have  none of the  rights of a
               shareholder with respect to the shares  purchasable upon exercise
               of the Option until a certificate for such shares shall have been
               issued to the holder upon due exercise of the Option.

          (g)  The proceeds  received by the Company upon  exercise of an Option
               shall be added to the Company's  working capital and be available
               for general corporate purposes.

8.       Non-Transferability of Incentive Options.

         No Incentive Option granted pursuant to this Plan shall be transferable
otherwise than by will or the laws of descent or  distribution  and an Incentive
Option may be exercised  during the  lifetime of the Option  holder only by such
Option holder.

9.       No Right of Employment.

         Nothing  in this  Plan or in any  Option  Agreement  granted  hereunder
shall:  (a) confer upon any Option holder any right to continue in the employ of
the Company or any  Subsidiary  or obligate  the  Company or any  Subsidiary  to
continue the engagement of any Option  holder;  or (b) interfere in any way with
the  right of the  Company  or any such  Subsidiary  to  terminate  such  Option
holder's employment or engagement at any time.

10.      Adjustments Upon Changes in Capitalization.

         If at any time after the date of grant of an Option,  the Company shall
by stock  dividend,  split-up,  combination,  reclassification  or exchange,  or
through merger or consolidation or otherwise,  change its shares of Common Stock
into a  different  number  or kind or class of  shares  or other  securities  or
property,  then the number of shares  covered  by such  Option and the price per
share  thereof  shall be  proportionately  adjusted  for any such  change by the
Board,  whose  determination  thereon shall be  conclusive.  In the event that a
fraction of a share results from the foregoing  adjustment,  said fraction shall
be  eliminated  and the price per share of the remaining  shares  subject to the
Option adjusted accordingly.







11.      Vesting of Rights Under Options.

         Nothing  contained in this Plan or in any  resolution  adopted or to be
adopted by the Board or the  shareholders  of the Company shall  constitute  the
vesting of any rights  under any Option.  The vesting of such rights  shall take
place only when a written  Option  Agreement,  substantially  in the form of the
Incentive  Stock  Option   Agreement   attached  hereto  as  Exhibit  A  or  the
Non-Incentive  Stock Option  Agreement  attached  hereto as Exhibit B (with such
changes to such Exhibits as may be necessary to reflect the terms and conditions
of the grant in question), shall be duly executed and delivered by and on behalf
of the  Company  and the person to whom the Option  shall be  granted,  subject,
however, in either event, to the rights granted to the Company and the Committee
hereunder and to the terms and conditions of the Option Agreement.

12.      Withholding Taxes.

         Whenever under this Plan shares are to be issued in satisfaction of the
exercise  of Options  granted  hereunder,  the  Company  shall have the right to
require the  recipient to remit to the Company an amount  sufficient  to satisfy
federal,  state and local withholding tax requirements  prior to the delivery of
any certificate or certificates for such shares.

13.      Restrictions on Shares.

         At the  discretion  of the Board,  the Company may reserve to itself or
its assignee(s) in the Option Agreement (a) a right of first refusal to purchase
any shares that an  Optionholder  (or a  subsequent  transferee)  may propose to
transfer to a third party and (b) a right to  repurchase  any or all shares held
by an Optionholder upon the Optionee's termination of employment or service with
the Company or a subsidiary for any reason within a specified time as determined
by the Board at the time of grant at (i) the  Optionholder's  original  purchase
price,  (ii) the Fair Market Value of such shares as  determined by the Board in
good faith,  or (iii) a price  determined by a provision set forth in the Option
Agreement.

14.      Termination and Amendment.

         The Board may at any time  terminate,  amend or modify this Plan in any
respect  (including,  but not  limited  to,  any  form of  grant,  agreement  or
instrument  to be  executed  pursuant  to this Plan);  provided,  however,  that
shareholder approval shall be required to be obtained by the Company if required
to comply with the Incentive Option provisions or Section 162(m) of the Code, or
the listed  company  requirements  of The Nasdaq  Stock  Market or of a national
securities  exchange on which the shares of Common  Stock are  traded,  or other
applicable  provisions  of state or  federal  law or  self-regulatory  agencies;
provided,  further, that no termination,  amendment or modification of this Plan
may materially  adversely affect the rights of a holder of an Option  previously
granted under this Plan without the written consent of such Optionholder.







15.      Term of Plan.

         This Plan was  originally  adopted by the Board of Directors on October
1, 1996 and approved by the  shareholders  of the Company on October 1, 1996. No
Option shall be granted  pursuant to this Plan on or after  September 30 , 2006,
but Options  theretofore  granted  may extend  beyond that date and the terms of
this Plan shall  continue  to apply to such  Options and to any shares of Common
Stock acquired upon exercise thereof.

16.      Applicable Law.

         The  validity,  interpretation  and  enforcement  of this Plan shall be
governed  in all  respects  by the laws of the State of New York and the  United
States of America.

17.      Issuance of Shares.

         The Shares,  when issued and paid for  pursuant to the Options  granted
hereunder, shall be fully paid and non-assessable Shares.

                                                                 EXHIBIT A
                                                                 ---------

                        INCENTIVE STOCK OPTION AGREEMENT
                                 ---------------

To:


         We are pleased to notify you that by the  determination of the Board of
Directors (hereinafter called the "Board") an incentive stock option to purchase
________  shares of the Common Stock of Manchester  Equipment Co., Inc.  (herein
called  the  "Company")  at a price of  $______  per  share has this ____ day of
_______________,  been granted to you under the  Company's  Amended and Restated

         A.       Purpose of Option.

                  The  purpose of this Plan under  which  this  incentive  stock

directors,  consultants,  agents,  independent contractors and other persons who
contribute and are expected to contribute materially to the Company's success to
obtain a  proprietary  interest in the Company  through the  ownership of stock,
thereby  providing  such  persons  with an added  incentive  to promote the best
interests of the Company, and affording the Company a means of attracting to its
service persons of outstanding ability.

          1.   Acceptance of Option Agreement.

     Your execution of this incentive stock option  agreement will indicate your
acceptance  of and your  willingness  to be bound by its  terms;  it  imposes no
obligation  upon you to purchase any of the shares  subject to the option.  Your
obligation to purchase shares can arise only upon your exercise of the option in
the manner set forth in Article 3 hereof.

          2. When Option May Be Exercised.

     The option  granted you hereunder may not be exercised for a period of [one
year]  from the date of its grant by the Board as set forth  above.  Thereafter,

          (i)  at the end of [one year]  from the date of grant,  up to [25%] of
               the total shares subject to the option;

         (ii)  at the end of the  [second  year]  from the date of grant,  up to
               [50%] of such shares;

        (iii)  at the end of the  [third  year]  from the date of  grant,  up to
               [75%] of such shares;

         (iv)  at the end of the  [fourth  year]  from the date of grant,  up to
               [100%] of such shares.




                                                         
This  option may not be  exercised  for less than ten shares at any one time (or
the remaining  shares then  purchasable if less than ten) and expires at the end
of ten years from the date of grant  whether or not it has been duly  exercised,
unless sooner terminated as provided in Articles 5, 6 and 7 hereof.

     3. How Option May Be Exercised.

     This option is  exercisable by a written notice signed by you and delivered
to the Company at its executive  offices,  signifying  your election to exercise
the  option.  The notice  must state the number of shares of Common  Stock as to
which your option is being exercised, must contain a statement by you (in a form
acceptable  to the  Company)  that such  shares  are being  acquired  by you for
investment  and not  with a view to  their  distribution  or  resale  (unless  a
registration  statement  covering  the  shares  purchasable  has  been  declared
effective by the Securities and Exchange  Commission) and must be accompanied by
payment  as set forth in  Article 4 hereof  for the full  purchase  price of the
share being purchased.  No share shall be issued until full payment therefor has
been made.

     If notice of the  exercise  of this  option is given by a person or persons
other than you, the Company may require,  as a condition to the exercise of this
option,  the submission to the Company of appropriate proof of the right of such
person or persons to exercise this option.

     Certificates  for shares of the Common Stock so purchased will be issued as
soon as  practicable.  The Company,  however,  shall not be required to issue or
deliver a certificate for any shares until it has complied with all requirements
of the Securities  Act of 1933,  the Securities  Exchange Act of 1934, any stock
exchange  on  which  the  Company's  Common  Stock  may then be  listed  and all
applicable  state laws in connection with the issuance or sale of such shares or
the  listing  of such  shares  on  said  exchange.  Until  the  issuance  of the
certificate  for such  shares,  you or such other  person as may be  entitled to
exercise  this  option,  shall  have none of the  rights of a  shareholder  with
respect to shares subject to this option.

     You shall promptly advise the Company of any sale of shares of Common Stock
issued upon  exercise of this option which  occurs  within one (1) year from the
date of the exercise of this option relating to the issuance of such shares.

     4. Payment of Options.

     Payment for the shares of Common  Stock may be made (i) in cash or by check
to the order of the Company;  (ii) by surrender of shares of Common Stock having
a Fair Market Value equal to the exercise  price of the Option;  or (iii) by any
combination of the foregoing where approved by the Board in its sole discretion;
provided,  however,  in the event of payment  for the shares of Common  Stock by
method (ii) above,  the shares of Common  Stock so  surrendered,  if  originally
issued to you upon exercise of an option(s)  granted by the Company,  shall have
been held by you for more than six months.









     5. Termination of Employment.

     If your employment with the Company (or a subsidiary thereof) is terminated
for any reason other than by death or  disability,  this option shall  terminate
three (3) months  from the date of such  termination  of  employment  (but in no
event  shall you be able to exercise  this option  after ten years from the date
this option was granted to you),  provided,  however, you shall only be entitled
to exercise that portion of this option which was exercisable by you at the date
of such termination of employment.

     6. Disability.

     If your employment with the Company (or a subsidiary thereof) is terminated
by reason of your  disability,  you may  exercise,  within one (1) year from the
date of such  termination,  that portion of this option which was exercisable by
you at the date of such  termination,  provided,  however,  that  such  exercise
occurs within ten years from the date this option was granted to you.

     7. Death.

     If you die while  employed  by the  Company  (or a  subsidiary  thereof) or
within one (1) year after termination of your employment due to disability, that
portion of this option  which was  exercisable  by you at the date of your death
may be exercised by your  legatee or legatees  under your Last Will,  or by your
personal  representatives or distributees,  within one (1) year from the date of
your death,  provided,  however, that such exercise occurs within ten years from
the date this option was granted to you.

     8. Non-Transferability of Option.

     This option  shall not be  transferable  except by Last Will or the laws of
descent and distribution, and may be exercised during your lifetime only by you.

     9. Adjustments upon Changes in Capitalization.

     If at any time after the date of grant of this option,  the Company  shall,
by stock  dividend,  split-up,  combination,  reclassification  or exchange,  or
through merger or consolidation, or otherwise, change its shares of Common Stock
into a  different  number  or kind or class of  shares  or other  securities  or
property, then the number of shares covered by this option and the price of each
such share shall be  proportionately  adjusted  for any such change by the Board
whose determination shall be conclusive.  Any fraction of a share resulting from
any  adjustment  shall be  eliminated  and the price per share of the  remaining
shares subject to this options adjusted accordingly.







     10. Subject to Terms of this Plan.

     This incentive  stock option  agreement shall be subject in all respects to
the  terms and  conditions  of this  Plan and in the  event of any  question  or
controversy  relating to the terms of this Plan, the decision of the Board shall
be conclusive.

                                        Sincerely yours,

                                        MANCHESTER EQUIPMENT CO., INC.

                      NON-INCENTIVE STOCK OPTION AGREEMENT
                                 ---------------

To:

                  We are pleased to notify you that by the  determination of the
Board of Directors (hereinafter called the "Board") a non-incentive stock option
to purchase _______ shares of the Common Stock of Manchester Equipment Co., Inc.
(herein  called the "Company") at a price of $_______ per share has this ___ day
of  ______________,  been  granted to you under the  Company's  1996 Amended and
Restated  Incentive  and  Non-Incentive  Stock Option Plan,  as amended  (herein
called  the  "Plan").  This  option  may be  exercised  only  upon the terms and
conditions set forth below.

     1. Purpose of Option.

     The purpose of this Plan under which this  non-incentive  stock  option has
been  granted is to further  the growth and  development  of the Company and its
direct and  indirect  subsidiaries  by  encouraging  key  employees,  directors,
consultants,  agents,  independent  contractors and other persons who contribute
and are expected to contribute  materially to the Company's  success to obtain a
proprietary  interest in the Company  through the  ownership  of stock,  thereby
providing such persons with an added  incentive to promote the best interests of
the Company,  and  affording  the Company a means of  attracting  to its service
persons of outstanding ability.

     2. Acceptance of Option Agreement.

     Your execution of this  non-incentive  stock option agreement will indicate
your acceptance of and your  willingness to be bound by its terms; it imposes no
obligation  upon you to purchase any of the shares  subject to the option.  Your
obligation to purchase shares can arise only upon your exercise of the option in
the manner set forth in Article 4 hereof.

     3. When Option May Be Exercised.

     The option granted you hereunder shall be exercisable as follows:

     This option may not be  exercised  for less than ten shares at any one time
(or the remaining  shares then  purchasable if less than ten) and expires at the
end of [indicate term of option, not to exceed ten years] years from the date of
grant whether or not it has been duly  exercised,  unless  sooner  terminated as
provided in Article 6 hereof.







     4. How Option May Be Exercised.

     This option is  exercisable by a written notice signed by you and delivered
to the Company at its executive  offices,  signifying  your election to exercise
the  option.  The notice  must state the number of shares of Common  Stock as to
which your option is being exercised, must contain a statement by you (in a form
acceptable  to the  Company)  that such  shares  are being  acquired  by you for
investment  and not  with a view to  their  distribution  or  resale  (unless  a
registration  statement  covering  the  shares  purchasable  has  been  declared
effective by the Securities and Exchange  Commission) and must be accompanied by
payment  as set forth in  Article 5 hereof  for the full  purchase  price of the
shares being purchased, plus such amount, if any, as is required for withholding
taxes. No share shall be issued until full payment therefor has been made.

     If notice of the  exercise  of this  option is given by a person or persons
other than you, the Company may require,  as a condition to the exercise of this
option,  the submission to the Company of appropriate proof of the right of such
person or persons to exercise this option.

     Certificates  for shares of the Common Stock so purchased will be issued as
soon as  practicable.  The Company,  however,  shall not be required to issue or
deliver a certificate for any shares until it has complied with all requirements
of the Securities  Act of 1933,  the Securities  Exchange Act of 1934, any stock
exchange  on  which  the  Company's  Common  Stock  may then be  listed  and all
applicable  state laws in connection with the issuance or sale of such shares or
the  listing  of such  shares  on  said  exchange.  Until  the  issuance  of the
certificate  for such  shares,  you or such other  person as may be  entitled to
exercise  this  option,  shall  have none of the  rights of a  shareholder  with
respect to shares subject to this option.

     5. Payment of Options.

     Payment for the shares of Common  Stock may be made (i) in cash or by check
to the order of the Company,  (ii) by surrender of shares of Common Stock having
a Fair Market Value equal to the exercise  price of the Option;  or (iii) by any
combination of the foregoing where approved by the Board in its sole discretion;
provided,  however,  in the event of payment  for the shares of Common  Stock by
method (ii) above,  the shares of Common  Stock so  surrendered,  if  originally
issued to you upon exercise of an option(s)  granted by the Company,  shall have
been held by you for more than six months.

     





6. Termination of Employment or Engagement.

     If your employment or engagement with the Company (or a subsidiary thereof)
is  terminated  for any reason,  [insert terms upon which  non-incentive  option
holder's options shall lapse and expire.] [Insert terms upon which non-incentive
options shall survive the  termination  of a holder's  employment or engagement,
but in such event the option shall be exercisable only to the extent exercisable
on the date of such  termination and in no event shall the option be exercisable
after the expiration  date of this option.] [If the option survives the death of
the option holder, add language that it may be exercised by the holder's legatee
or  legatees  under  his  Last  Will,  or by  his  personal  representatives  or
distributees.]

     7. Adjustments upon Changes in Capitalization.

     If at any time after the date of grant of this option,  the Company  shall,
by stock  dividend,  split-up,  combination,  reclassification  or exchange,  or
through merger or consolidation, or otherwise, change its shares of Common Stock
into a  different  number  or kind or class of  shares  or other  securities  or
property, then the number of shares covered by this option and the price of each
such share shall be  proportionately  adjusted  for any such change by the Board
whose determination shall be conclusive.  Any fraction of a share resulting from
any  adjustment  shall be  eliminated  and the price per share of the  remaining
shares subject to this option adjusted accordingly.

     8. Subject to Terms of this Plan.

     This non-incentive  stock option agreement shall be subject in all respects
to the terms and  conditions  of this Plan and in the event of any  question  or
controversy  relating to the terms of this Plan, the decision of the Board shall
be conclusive.

     9. Tax Status.

     This option  does not  qualify as an  "incentive  stock  option"  under the
provisions of Section 422 of the Internal Revenue Code of 1986, as amended,  and
the income tax implications of your receipt of a non-incentive  stock option and
your exercise of such an option should be discussed with your tax counsel.

                                        Sincerely yours,

                                        MANCHESTER EQUIPMENT CO., INC.
