hereof, fully paid and non-assessable, during the following periods.
      
  (a) No shares may be purchased  prior to the  expiration of twelve (12)
months from the date of this option (unless otherwise authorized by the Board of
Directors) or after ten (10) years from the date thereof.

         (b) All or any part of ____ shares may be purchased during the period
commencing  _________  and terminating at 5:00 p.m. on ______________.

2. PURCHASE PRICE. The purchase price shall be ______ per share, payable in cash
or by check  (subject to  collection)  to the  Grantor,  or in the  alternative,
payment  may be made by delivery  of common  stock of the Grantor  valued at the
closing price of such common stock on the New York Stock Exchange on the date of
exercise.  The Grantor  shall pay all  original  issue or transfer  taxes on the
exercise of this option and all other fees and expenses  necessarily incurred by
the Grantor in connection therewith.

3. EXERCISE OF OPTION.  The Optionee shall notify the Grantor by registered mail
addressed  to its  principal  offices as to the number and class of shares which
Optionee  desires to purchase  under the options  herein  granted,  which notice
shall be accompanied by payment (by cash, check or stock of the Grantor as above
provided)  of the option price  therefore as specified in paragraph 2 above.  As
soon as possible  thereafter the Grantor shall, at its principal office,  tender
to Optionee  certificates  issued in the Optionee's  name  evidencing the shares
purchased by the Optionee.



4.  OPTION CONDITIONED ON CONTINUED EMPLOYMENT.

(a) Each of the aforesaid options shall terminate and be void if the Optionee is
not in the  employ  of the  Grantor  on the date in which  such  option is first
exercisable.

(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 event  after  the
expiration  of the last  option  herein  contained,  provided if  employment  is
terminated  for cause or without the Optionee  having given  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 whole
number of shares included therein.

(b) The Optionee may not give,  grant,  sell,  exchange,  transfer  legal title,
pledge, assign or otherwise encumber or dispose of the options herein granted or
any  interest  therein,  otherwise  than  by will or the  laws  of  descent  and
distribution,  and these options,  or any of them,  shall be exercisable  during
Optionee's lifetime only by the Optionee.

(c) In the event of the Optionee's death while employed by the Grantor or within
three (3)  months of the  termination  of  Optionee's  employment  [unless  such
termination was either for cause or without the Optionee having given 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.

                                      GENERAL DATACOMM INDUSTRIES, INC.


                                      By: ________________________________
