TII INDUSTRIES, INC.

                    1983 Employee Incentive Stock Option Plan
                    -----------------------------------------
                     (as amended effective August 15, 1996)

            1.          Purpose.   The  TII   Industries,   Inc.  1983  Employee
Incentive Stock Option Plan (the "Plan") is intended to provide a method whereby
employees  (including  officers and  directors)  of TII  Industries,  Inc.  (the
"Company")  and its  subsidiaries  who are making and are  expected  to continue
making substantial  contributions to the successful management and growth of the
Company and its  subsidiaries  may be offered an  opportunity  to acquire common
stock,  $.01 par value per share  ("Common  Stock"),  of the Company in order to
increase  their  proprietary  interests  in the Company and their  incentive  to
remain  in and  advance  in the  employ  of the  Company  and its  subsidiaries.
Accordingly,  the Company may, from time to time, grant to such employees as may
be selected in the manner  hereinafter  provided  incentive  stock  options,  as
defined in Section 422 of the Internal Revenue Code of 1986, as amended,  or any
corresponding  provisions of any  succeeding  law ("Code"),  to purchase  Common
Stock of the Company  ("Incentive  Stock Options" or "Options") on the terms and
conditions hereinafter set forth.

            2.          Administration.  The Plan shall be  administered  by the
Board of  Directors  of the Company  (the "Board of  Directors")  which,  to the
extent  it  shall  determine,  may  delegate  its  powers  with  respect  to the
administration  of the Plan to a committee  (the  "Committee")  appointed by the
Board of Directors, the Committee to consist of two or more members of the Board
of Directors,  each of whom is a "non-employee  director"  within the meaning of
Rule 16b-3 of the rules and regulations (as amended,  "Rule 16b-3")  promulgated
by the Securities and Exchange  Commission under the Securities  Exchange Act of
1934 (the "Exchange Act").  References in the Plan to  determinations or actions
by the Committee  shall be deemed to include  determinations  and actions by the
Board of  Directors.  Subject  to the terms  and  conditions  of the  Plan,  the
Committee shall have exclusive authority to select the employees to whom Options
shall be  granted,  to  determine  the  number of  shares of Common  Stock to be
covered by each  Option,  the time at which each option  shall be  granted,  the
Option  Exercise Price (as hereinafter  defined),  the term during which options
may be  exercised  and the form of  option  agreement  under  the Plan  ("Option
Agreement").

            The Board of Directors may at any time appoint or remove  members of
the  Committee  and may fill  vacancies  however  caused in the  Committee.  The
Committee  shall  select one of its members as its  Chairman  and shall hold its
meetings at such time and place and in such  manner as it shall deem  advisable.
All actions of the Committee shall be taken by a majority of its members and can
be taken by unanimous written consent in lieu of a meeting.  The Committee shall
keep records of its meetings and shall make such rules and  regulations  for the
conduct of its business as it shall deem advisable.

            3.          Interpretation  and Amendment.  The  interpretation  and
construction of any terms or conditions of the Plan, or of any Option  Agreement
or other  matters  related  to the  Plan,  by the  Committee  shall be final and
conclusive. No member of the Board of Directors or the Committee shall be liable
for any action or determination made in good faith with respect to the Plan.







            The Board of  Directors  may at any time  terminate  or from time to
time modify or suspend the Plan;  provided,  however,  that no such action shall
impair any Incentive Stock Options  theretofore  granted;  and provided further,
that without the  affirmative  vote of the holders of at least a majority of the
voting stock of the Company present,  or represented,  and entitled to vote at a
duly held  meeting:  (a) the total number of shares of Common Stock which may be
issued under the Plan (except as permitted by Section 9) or the  aggregate  fair
market value of shares of Common stock which may be issued under the Plan to any
one employee shall not be increased;  (b) the Option Exercise Price shall not be
decreased  (except as  permitted by Section 9) ; (c) the term of the Plan or any
Incentive Stock Option shall not be extended; (d) requirements as to eligibility
for  participation  in the Plan  shall  not be  modified;  and (e) the  benefits
accruing to participants under the Plan shall not be materially increased.

            4.          Participants.  Incentive  Stock Options shall be granted
to  employees  of the  Company  or its  subsidiaries  who  are  selected  by the
Committee from time to time.  The term  "employees"  shall include  officers and
directors  who are  employees  of the  Company  or its  subsidiaries.  The  term
"parent" or a  "subsidiary'  shall mean "parent  corporation"  or a  "subsidiary
corporation"  as defined in Section 424 of the Code.  No Incentive  Stock Option
shall be granted to an employee  who,  at the time the  Incentive  Stock  Option
would  otherwise be granted,  owns (or is deemed to own under Section  424(d) of
the Code)  capital  stock  possessing  more than ten percent  (10%) of the total
combined  voting power of all classes of capital  stock of the  Company,  or any
parent or any subsidiary of the Company;  provided,  however,  that an Incentive
Stock Option may be granted to such an employee if the Option Exercise Price per
share of Common  Stock to be acquired by the exercise of such Option is at least
one hundred and ten percent  (110%) of the fair market value per share of Common
Stock at the time such  Option is granted,  and such  Option is not  exercisable
after the expiration of five (5) years from the date such Option is granted.

            Receipt  of  stock   options  under  any  other  stock  option  plan
maintained by the Company or any subsidiary shall not, for that reason, preclude
an employee from receiving Incentive Stock Options under the Plan.

            5.          Shares of Common Stock  Subject to the Plan.  Subject to
Section 9, no more than an aggregate of six hundred  twenty  thousand  (620,000)
shares of Common Stock may be issued and sold  pursuant to the Plan.  The shares
of Common Stock issued and sold under the Plan will be the Company's  authorized
but unissued shares of Common Stock.

            Should any Incentive Stock Option expire or terminate for any reason
without having been exercised in full, the unsold shares of Common Stock covered
thereby  shall be added to the shares of Common Stock  otherwise  available  for
option hereunder.

            The aggregate fair market value (determined at the time an Incentive
Stock  Option is granted) of the shares of Common  Stock for which any  employee
may be granted  Incentive  Stock  Options in any  calendar  year or part thereof
through January 8, 1992 may not exceed $100,000 plus

                                       -2-





any available carryover for such year. The term "available carryover" shall mean
the "unused  limit  carryover"  permitted by Section  422A(c)(4) of the Code (as
such  section  existed  prior to its  repeal).  In the case of  Incentive  Stock
Options  granted to any employee  after  December 31, 1986,  the aggregate  fair
market value  (determined  at the time an Incentive  Stock Option is granted) of
the shares of Common Stock with  respect to which  Incentive  Stock  Options are
exercisable  for the first time by such employee  during any calendar year shall
not exceed $100,000.

            6.          Terms and Conditions of Options. Incentive Stock options
shall be in such form and on such terms and  conditions as the  Committee  shall
from time to time approve,  subject to the following  terms and  conditions  (in
addition to those specifically required by other provisions in this Plan):

                        (a) An Incentive  Stock option shall state the number of
            shares of Common Stock to which it relates and no fractional  shares
            of Common Stock shall be issued.

                        (b) The option price per share of Common Stock  issuable
            upon the exercise of an Incentive  Stock  Option  ("Option  Exercise
            Price")  shall not be less than one  hundred  percent  (100%) of the
            fair market  value per share of Common Stock on the date of grant of
            such Option.

                        (c) The term of an  incentive  Stock option shall not be
            more than ten (10) years from the date such Option is granted.

                        (d) An Incentive  Stock Option  granted prior to January
            9, 1992 may not be exercised while there is outstanding  (within the
            meaning of Section  422A(c)(7) of the Code, as such section  existed
            prior to its repeal) any  incentive  stock  option which was granted
            before the granting of such  Incentive  Stock Option to the employee
            to purchase any capital  stock in the Company or in any  corporation
            which, at the time of granting of such Incentive Stock Option,  is a
            parent or a subsidiary  corporation  the Company or any  predecessor
            corporation of any such corporation.

            7.          Termination of Employment.  In the event that the holder
of an Option  granted  pursuant  to the Plan shall  cease to be  employed by the
Company or by a subsidiary  of the Company for any reason other than  disability
(within  the  meaning of Section  22(e)(3)  of the  Code),  retirement  with the
consent of the Company or death,  any Incentive  Stock  Options  granted to such
person  pur suant to the Plan  shall  terminate  on the date of  termination  of
employment  or on a date  not more  than  three  (3)  months  after  the date of
termination   of  employment  (as  determined  by  the  Committee  in  its  sole
discretion) , but in no event may an Incentive  Stock Option be exercised  after
the date on which such Option would have expired and,  during such period as the
Incentive  Stock option may be  exercised,  such Option may only be exercised to
the extent  exercisable at the date of termination of employment.  If the holder
of an Incentive  Stock option ceases to be employed by reason of such disability
or retires with the consent of the Company,  such Option shall terminate one (1)
year after the date of disability  and not later than three (3) months after the
date of retirement (as determined

                                       -3-





by the  Committee),  but in no event may an Incentive  Stock Option be exercised
after the date on which  such  Option  would have  (except  for  termination  of
employment) expired and, during such period as the Incentive Stock Option may be
exercised,  such Option may only be exercised to the extent  exercisable  at the
date of termination of employment.

            Solely for purposes of the Plan,  the  transfer of an employee  from
the employ of the  Company  to the employ of a  subsidiary  of the  Company,  or
vice-versa, or from one subsidiary of the Company to another shall not be deemed
a termination of employment.

            8.          Death.  If an employee  shall die while  employed by the
Company or by any subsidiary of the Company or during the periods referred to in
Section 7 during  which an Option may be  exercised,  then his estate,  personal
representative or beneficiary shall have the right, for a period of one (1) year
(or within such  shorter  period as may be  specified  by the  Committee  in the
Option  Agreement)  after the employee dies, to exercise those  Incentive  Stock
Options granted to the employee which were exercisable by him at the time of his
death, but in no event may an Incentive Stock Option be exercised after the date
on which such Option would have (except for termination of employment) expired.

            9.          Stock Splits,  Mergers, etc. In case of any stock split,
stock dividend or similar transaction which increases or decreases the number of
outstanding shares of Common Stock,  appropriate adjustment shall be made by the
Board of Directors,  whose determination shall be final, to the number of shares
of Common Stock which may be purchased  under the Plan and the number and Option
Exercise  Price of the shares of Common Stock which may be  purchased  under any
outstanding  Incentive Stock Options. In the case of a merger, sale of assets or
similar transaction which results in a replacement of the shares of Common Stock
with stock of another  corporation,  the Company will make a reasonable  effort,
but shall not be required,  to replace any  outstanding  Incentive Stock Options
with comparable options to purchase the stock of such other corporation, or will
provide for immediate exercisability of all outstanding Incentive Stock Options,
with all Incentive Stock Options which are not exercised  within the time period
specified by the Board of Directors being terminated.

            10.         Transferability.  Incentive  Stock  Options shall not be
assignable  or  transferable   except  by  will  or  the  laws  of  descent  and
distribution and, during an employee's lifetime, may be exercised only by him.

            11.         Option Agreements.  Option Agreements granting Incentive
Stock Options under the Plan shall be in writing, duly executed and delivered by
or on behalf of the Company and the  employee  and shall  contain such terms and
conditions as the Committee deems  advisable.  If there is any conflict  between
the terms and conditions of any Option  Agreement and of the Plan, the terms and
conditions of the Plan shall control.

            12.         Exercise of Options. An employee electing to exercise an
Incentive Stock Option shall give written notice to the Company of such election
and of the number of shares of

                                       -4-




Common Stock which he has elected to acquire.  An employee  shall have no rights
of a  shareholder  with  respect to the shares of Common Stock to be acquired by
the  exercise  of an  Incentive  Stock  Option  until the  issuance  to him of a
certificate  representing such Common Stock; provided,  however, that until such
certificates  are issued,  any employee using existing shares of Common Stock in
payment of an Option  Exercise Price  (pursuant to Section 13) shall continue to
have the rights of a stockholder  with respect to such existing shares of Common
Stock.

            It is a  condition  to the  exercise of any Option that either (a) a
Registration  Statement  under  the  Securities  Act of 1933,  as  amended  (the
"Securities Act"), with respect to such shares shall be effective at the time of
exercise or (b) there is an exemption from registration under the Securities Act
for the issuance of shares of Common Stock upon such  exercise.  Nothing  herein
shall be construed as requiring the Company to register, or perfect an exception
from registration of, the shares subject to any Option under the Securities Act.
Each Option shall be subject to the further requirement that, if at any time the
Committee shall determine, in its discretion,  that the listing or qualification
of the  shares  subject  to such  Option  on any  securities  exchange  or under
applicable law, or the consent or approval of any governmental  regulatory body,
is  necessary  or  desirable  as a con dition  of, or in  connection  with,  the
granting of such Option, or the issue of shares thereunder,  such Option may not
be exercised in whole or in part unless such listing, qualification,  consent or
approval  shall  have been  effected  or  obtained  free of any  conditions  not
acceptable to the Committee.

            13.         Payment. The Option Exercise Price shall be payable upon
the  exercise  of an  Incentive  Stock  Option  and  shall be paid in  cash,  by
certified  check  or in  shares  of  Common  Stock,  in  the  discretion  of the
Committee.  If shares of Common  Stock are  tendered  as  payment  of the Option
Price, the value of such shares of Common Stock shall be their fair market value
as of the date of exercise.

            14.         Continuance  of  Employment.  Neither  the  Plan nor any
Option Agreement shall impose any obligation on the Company or any subsidiary to
continue to employ any employee.

            15.         Term of Plan. No Incentive Stock Option shall be granted
pursuant to the Plan after May 8, 1993.

                                       -5-
