1995 STOCK OPTION PLAN

                                       of

                              TII INDUSTRIES, INC.
                     (as amended effective August 15, 1996)


            1.          PURPOSES  OF THE  PLAN.  This  stock  option  plan  (the
"Plan") is designed to provide an incentive to  employees  (including  directors
and officers who are employees) and to consultants  who are not employees of TII
Industries,  Inc., a Delaware  corporation (the "Company"),  and its present and
future subsidiary corporations, as defined in Paragraph 19 ("Subsidiaries"), and
to offer an additional  inducement  in obtaining the services of such  employees
and  consultants.  The Plan provides for the grant of "incentive  stock options"
("ISOs") within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"),  and nonqualified stock options which do not qualify as
ISOs ("NQSOs"), but the Company makes no representation or warranty,  express or
implied,  as to the  qualification  of any option as an "incentive stock option"
under the Code.

            2.          STOCK SUBJECT TO THE PLAN.  Subject to the provisions of
Paragraph 12, the aggregate number of shares of common stock, $.01 par value per
share,  of the Company  ("Common  Stock") for which options may be granted under
the Plan shall not  exceed  500,000.  Such  shares of Common  Stock may,  in the
discretion of the Board of Directors of the Company (the "Board of  Directors"),
consist either in whole or in part of authorized  but unissued  shares of Common
Stock or shares of Common Stock held in the treasury of the Company.  Subject to
the  provisions of Paragraph 13, any shares of Common Stock subject to an option
which for any reason expires, is canceled or is terminated  unexercised or which
ceases for any reason to be  exercisable  shall again become  available  for the
granting of options  under the Plan.  The Company  shall at all times during the
term of the Plan  reserve  and keep  available  such  number of shares of Common
Stock as will be suf ficient to satisfy the requirements of the Plan.

            3.          ADMINISTRATION   OF  THE   PLAN.   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 of the Board of  Directors  (the
"Committee") consisting of not less than two directors,  each of whom shall be a
"non-employee  director" within the meaning of Rule 16b-3 (or any successor rule
or regulation) promulgated under the Securities Exchange Act of 1934, as amended
(as the same may be in effect and interpreted  from time to time, "Rule 16b-3").
References in the Plan to  determinations  or actions by the Committee  shall be
deemed to  include  determinations  and  actions  by the Board of  Directors.  A
majority of the members of the Committee shall constitute a quorum, and the acts
of a majority of the







members  present  at any  meeting  at which a quorum  is  present,  and any acts
approved in writing by all members  without a meeting,  shall be the acts of the
Committee.

            Subject to the express  provisions of the Plan, the Committee  shall
have the authority,  in its sole discretion,  to determine the employees and the
consultants  who shall be  granted  options;  the times  when  options  shall be
granted; whether an option granted to an employee shall be an ISO or a NQSO; the
number of shares of Common Stock to be subject to each option;  the term of each
option; the date each option shall become  exercisable;  whether an option shall
be exercisable in whole, in part or in installments and, if in installments, the
number of shares of Common Stock to be subject to each install ment, whether the
installments  shall  be  cumulative,  the date  each  installment  shall  become
exercisable and the term of each installment;  whether to accelerate the date of
exercise of any option or  installment;  whether  shares of Common  Stock may be
issued upon the  exercise of an option as partly paid and, if so, the dates when
future  installments  of the exercise  price shall become due and the amounts of
such installments; the exercise price of each option; the form of payment of the
exercise  price;  the fair market value of a share of Common  Stock;  whether to
restrict the sale or other  disposition  of the shares of Common Stock  acquired
upon  the  exercise  of an  option  and,  if  so,  whether  to  waive  any  such
restriction;  whether to subject the exercise of all or any portion of an option
to the fulfillment of contingencies as specified in the contract  referred to in
Paragraph  11 (the  "Contract"),  including  without  limitation,  contingencies
relating to entering into a covenant not to compete with the Company, any of its
Subsidiaries  or a Parent (as defined in Paragraph 19), to financial  objectives
for the Company,  any of its  Subsidiaries or a Parent, a division of any of the
foregoing,  a product  line or other  category,  and/or the period of  continued
employment  of the  optionee  with the  Company,  any of its  Subsidiaries  or a
Parent,  and to determine whether such  contingencies have been met; the amount,
if any, necessary to satisfy the Company's obligation to withhold taxes or other
amounts;  whether an  optionee  is Disabled  (as  defined in  Paragraph  19); to
construe  the  respective  Contracts  and the  Plan;  with  the  consent  of the
optionee, to cancel or modify an option,  provided such modified provision would
be  permitted  to be  included  in an  option on the date of  modification,  and
further,  provided,  that, in the case of a modification  (within the meaning of
Section  424(h)  of the  Code)  of an ISO,  such  option  as  modified  would be
permitted to be granted on the date of such modification  under the terms of the
Plan; to  prescribe,  amend and rescind  rules and  regulations  relating to the
Plan;  and  to  make  all  other  determinations   necessary  or  advisable  for
administering  the Plan. Any  controversy or claim arising out of or relating to
the Plan,  any option granted under the Plan or any Contract shall be determined
unilaterally by the Committee in its sole discretion.  The determinations of the
Committee on the matters referred to in this Paragraph 3 shall be conclusive and
binding on the parties.  No member or former  member of the  Committee  shall be
liable for any action,  failure to act or determination  made in good faith with
respect to the Plan or any option hereunder.

            4.          ELIGIBILITY. The Committee may from time to time, in its
sole  discretion,  consistent  with the purposes of the Plan,  grant  options to
employees  (including  officers  and  directors  who are  employees)  of, and to
consultants  to, the Company or any of its  Subsidiaries.  Such options  granted
shall cover such number of shares of Common Stock as the Committee may determine
in its sole  discretion;  provided,  however,  that the maximum number of shares
subject to options that may

                                       -2-






be granted to any employee  during any calendar year under the Plan (the "162(m)
Maximum")  shall not exceed  100,000  shares;  and further,  provided,  that the
aggregate  market  value  (determined  at the  time the  option  is  granted  in
accordance  with  Paragraph  5) of the  shares  of  Common  Stock  for which any
eligible  employee  may be granted  ISOs under the Plan or any other plan of the
Company,  or of a Parent or a Subsidiary of the Company,  which are  exercisable
for the first time by such  optionee  during any calendar  year shall not exceed
$100,000.  Such  limitation  shall be applied by taking ISOs into account in the
order in which they were granted. Any option (or the portion thereof) granted in
excess of such amount shall be treated as an NQSO.

            5.          EXERCISE  PRICE.  The  exercise  price of the  shares of
Common Stock under each option shall be  determined by the Committee in its sole
discretion;  provided,  however,  the exercise price of an ISO shall not be less
than the fair  market  value of the Common  Stock  subject to such option on the
date of grant;  and further,  provided,  that if, at the time an ISO is granted,
the optionee owns (or is deemed to own under  Section  424(d) of the Code) stock
possessing  more than 10% of the total  combined  voting power of all classes of
stock of the Company,  of any of its  Subsidiaries or of a Parent,  the exercise
price of such ISO shall not be less  than 110% of the fair  market  value of the
Common Stock subject to such ISO on the date of grant.

            The fair market value of a share of Common Stock on any day shall be
(a) if the  principal  market  for the  Common  Stock is a  national  securities
exchange, the average of the highest and lowest sales prices per share of Common
Stock on such day as reported by such exchange or on a composite tape reflecting
transactions on such exchange,  (b) if the principal market for the Common Stock
is not a national  securities  exchange  and the  Common  Stock is quoted on The
Nasdaq Stock Market  ("Nasdaq"),  and (i) if actual sales price  information  is
available  with  respect to the Common  Stock,  the  average of the  highest and
lowest sales prices per share of Common Stock on such day on Nasdaq,  or (ii) if
such  information  is not  available,  the average of the highest bid and lowest
asked  prices  per share of Common  Stock on such day on  Nasdaq,  or (c) if the
principal market for the Common Stock is not a national  securities exchange and
the Common  Stock is not quoted on Nasdaq,  the  average of the  highest bid and
lowest asked prices per share of Common Stock on such day as reported on the OTC
Bulletin  Board  Service or by  National  Quotation  Bureau,  Incorporated  or a
comparable service; provided,  however, that if clauses (a), (b) and (c) of this
Paragraph are all inapplicable,  or if no trades have been made or no quotes are
available  for such day,  the fair  market  value of the Common  Stock  shall be
determined by the Board by any method  consistent  with  applicable  regulations
adopted by the Treasury Department relating to stock options.

            6.          TERM.  The term of each option  granted  pursuant to the
Plan  shall  be such  term  as is  established  by the  Committee,  in its  sole
discretion; provided, however, that the term of each ISO granted pursuant to the
Plan  shall  be for a  period  not  exceeding  10  years  from the date of grant
thereof;  and  further,  provided,  that if, at the time an ISO is granted,  the
optionee  owns (or is  deemed  to own under  Section  424(d) of the Code)  stock
possessing  more than 10% of the total  combined  voting power of all classes of
stock of the Company, of any of its Subsidiaries or of a Parent, the term

                                       -3-






of the ISO  shall be for a period  not  exceeding  five  years  from the date of
grant. Options shall be subject to earlier termination as hereinafter provided.

            7.          EXERCISE.   An  option  (or  any  part  or   installment
thereof),  to the extent then exercisable,  shall be exercised by giving written
notice to the Company at its  principal  office  stating  which  option is being
exercised,  specifying  the  number of shares of Common  Stock as to which  such
option is being  exercised and  accompanied  by payment in full of the aggregate
exercise price  therefor (or the amount due on exercise if the Contract  permits
installment payments) (a) in cash or by certified check or (b) if the applicable
Contract permits,  with the consent of the Committee,  with previously  acquired
shares of Common  Stock  having an  aggregate  fair market  value on the date of
exercise  (determined  in  accordance  with  Paragraph 5) equal to the aggregate
exercise price of all options being exercised,  or with any combination of cash,
certified check or shares of Common Stock

            The Committee  may, in its sole  discretion,  permit  payment of the
exercise  price of an option by delivery by the optionee of a properly  executed
notice,  together with a copy of the optionee's  irrevocable  instructions  to a
broker acceptable to the Committee to deliver promptly to the Company the amount
of sale or loan proceeds  sufficient to pay such exercise  price.  In connection
therewith, the Company may enter into agreements for coordinated procedures with
one or more brokerage firms.

            A person  entitled to receive  Common  Stock upon the exercise of an
option shall not have the rights of a stockholder with respect to such shares of
Common Stock until the date of issuance of a stock  certificate  to him for such
shares;  provided,  however,  that until such stock  certificate is issued,  any
optionee  using  previously  acquired  shares of Common  Stock in  payment of an
option  exercise price shall  continue to have the rights of a stockholder  with
respect to such previously acquired shares.

            In no case may a fraction of a share of Common Stock be purchased or
issued under the Plan.

            8.          TERMINATION OF RELATIONSHIP.  Except as may otherwise be
expressly provided in the applicable  Contract,  any optionee whose relationship
with the Company,  its  Subsidiaries and Parent as an employee or consultant has
terminated for any reason (other than his death or Disability) may exercise such
option, to the extent  exercisable on the date of such termination,  at any time
within three months after the date of termination,  but not thereafter and in no
event after the date the option would otherwise have expired; provided, however,
that if such relationship is terminated either (a) for cause, or (b) without the
consent of the Company, such option shall terminate immediately.

            For the purposes of the Plan,  an employment  relationship  shall be
deemed to exist between an individual  and a corporation  if, at the time of the
determination,  the individual was an employee of such  corporation for purposes
of Section 422(a) of the Code. As a result, an individual

                                       -4-






on military, sick leave or other bona fide leave of absence shall continue to be
considered  an employee for purposes of the Plan during such leave if the period
of the leave does not exceed 90 days, or, if longer, so long as the individual's
right to reemployment with the Company (or a related  corporation) is guaranteed
either by statute or by contract. If the period of leave exceeds 90 days and the
individual's  right to reemployment is not guaranteed by statute or by contract,
the employment  relationship  shall be deemed to have terminated on the 91st day
of such leave.

            Notwithstanding the foregoing,  except as may otherwise be expressly
provided in the applicable Contract, options granted under the Plan shall not be
affected  by any change in the status of the  optionee  so long as the  optionee
continues  to be an employee of, or a  consultant  to, the  Company,  any of its
Subsidiaries or a Parent  (regardless of having changed from one to the other or
having been transferred from one corporation to another).

            Nothing  in the Plan or in any option  granted  under the Plan shall
confer  on any  optionee  any  right  to  continue  in the  employ  of,  or as a
consultant to, the Company, its Parent or any of its Subsidiaries,  or interfere
in any way with any right of the Company,  its Parent or any of its Subsidiaries
to terminate the optionee's  relationship at any time for any reason  whatsoever
without liability to the Company, its Parent or any of its Subsidiaries.

            9.          DEATH  OR  DISABILITY  OF AN  OPTIONEE.  Except  as  may
otherwise be expressly  provided in the  applicable  Contract,  if an individual
optionee  dies (a) while he is an employee of, or a consultant  to, the Company,
any of  its  Subsidiaries  or a  Parent,  (b)  within  three  months  after  the
termination  of such  relationship  (unless  such  termination  was for cause or
without  the  consent  of the  Company)  or (c) within  one year  following  the
termination  of such  relationship  by reason of  Disability,  his option may be
exercised,  to the extent  exercisable  on the date of his  death,  by his Legal
Representative  (as defined in  Paragraph  19) at any time within one year after
death,  but not  thereafter  and in no event  after  the date the  option  would
otherwise have expired.

            Except as may  otherwise  be  expressly  provided in the  applicable
Contract, any optionee whose relationship as an employee of, or a consultant to,
the Company, its Parent or any Subsidiary has terminated by reason of Disability
may exercise his option,  to the extent  exercisable  upon the effective date of
such  termination,  at any  time  within  one  year  after  such  date,  but not
thereafter  and in no event  after  the date the  option  would  otherwise  have
expired.


            10.         COMPLIANCE  WITH  SECURITIES  LAWS. 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 the
shares of Common Stock to be issued upon such  exercise  shall be effective  and
current at the time of exercise,  or (b) there be an exemption from registration
under the  Securities  Act for the  issuance of the shares of Common  Stock upon
such  exercise.  Nothing  herein shall be construed as requiring  the Company to
register  shares  subject to any option under the  Securities Act or to keep any
Registration Statement effective or current.

                                       -5-






            The Committee may require, in its sole discretion, as a condition to
the exercise of any option that the optionee  execute and deliver to the Company
his representations and warranties, in form, substance and scope satisfactory to
the  Committee,  which the Committee  determines  are necessary or convenient to
facilitate the perfection of an exemption from the registration  requirements of
the Securities Act or other legal requirement, including without limitation that
(a) the shares of Common  Stock to be issued upon the exercise of the option are
being acquired by the optionee for his own account,  for investment only and not
with a view to the resale or distribution thereof, and (b) any subsequent resale
or  distribution  of shares of Common Stock by such  optionee  will be made only
pursuant  to (i) a  Registration  Statement  under the  Securities  Act which is
effective  and current with respect to the shares of Common Stock being sold, or
(ii) a specific  exemption from the registration  requirements of the Securities
Act, but in claiming such  exemption,  the optionee  shall prior to any offer of
sale or sale of such shares of Common Stock provide the Company with a favorable
written opinion of counsel  satisfactory to the Company, in form,  substance and
scope satisfactory to the Company,  as to the applicability of such exemption to
the proposed sale or distribution.

            In addition,  if at any time the Committee shall  determine,  in its
sole discretion, that the listing or qualification of the shares of Common Stock
subject  to  such  option  on any  securities  exchange,  Nasdaq  or  under  any
applicable law, or the consent or approval of any governmental  regulatory body,
is necessary or desirable as a condition to, or in connection with, the granting
of an option or the issue of shares of Common Stock 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.

            11.         STOCK OPTION  CONTRACTS.  Each option shall be evidenced
by an  appropriate  Contract which shall be duly executed by the Company and the
optionee,   and  shall  contain  such  terms,   provisions  and  conditions  not
inconsistent herewith as may be determined by the Committee.

            12.         ADJUSTMENTS   UPON   CHANGES   IN  COMMON   STOCK.   Not
withstanding  any other provision of the Plan, in the event of a stock dividend,
split-up, combination,  reclassification,  recapitalization, merger in which the
Company is the  surviving  corporation,  or exchange of shares or the like which
results in a change in the number or kind of those  shares of Common Stock which
are outstanding  immediately  prior to such event, the aggregate number and kind
of shares subject to the Plan,  the aggregate  number and kind of shares subject
to each  outstanding  option  and the  exercise  price  thereof,  and the 162(m)
Maximum  shall  be  appropriately  adjusted  by the  Board of  Directors,  whose
determination shall be conclusive and binding on all parties.

            In the event of (a) the  liquidation  or dissolution of the Company,
or (b) a merger in which  the  Company  is not the  surviving  corporation  or a
consolidation,  any outstanding options shall terminate upon the earliest of any
such event, unless other provision is made therefor in the transaction.


                                       -6-






            13.         AMENDMENTS  AND  TERMINATION  OF THE PLAN.  The Plan was
adopted  by the Board of  Directors  on  September  20,  1995.  No option may be
granted under the Plan after September 19, 2005. The Board of Directors, without
further  approval  of the  Company's  stockholders,  may at any time  suspend or
terminate  the Plan,  in whole or in part, or amend it from time to time in such
respects as it may deem advisable,  including, without limitation, in order that
ISOs granted hereunder meet the requirements for "incentive stock options" under
the Code,  to comply  with,  conform to or adopt the  provisions  of Rule 16b-3,
Section 162(m) of the Code or any change in applicable law, regulations, rulings
or  interpretations  of  administrative  agencies;  provided,  however,  that no
amendment  shall  be  effective   without  the  requisite  prior  or  subsequent
stockholder  approval  which would (a) except as  contemplated  in Paragraph 12,
increase the maximum  number of shares of Common Stock for which  options may be
granted  under the Plan or the  162(m)  Maximum,  (b)  materially  increase  the
benefits  accruing to participants  under the Plan or (c) change the eligibility
requirements  to  receive  options  hereunder.  No  termination,  suspension  or
amendment  of the Plan  shall,  without the consent of the holder of an existing
and outstanding option affected thereby,  adversely affect his rights under such
option.  The power of the  Committee  to  construe  and  administer  any options
granted  under  the Plan  prior to the  termination  or  suspension  of the Plan
nevertheless shall continue after such termination or during such suspension.

            14.         NON-TRANSFERABILITY  OF OPTIONS. No option granted under
the Plan shall be transferable otherwise than by will or the laws of descent and
distribution, and options may be exercised, during the lifetime of the optionee,
only by the optionee or his Legal Representatives. Except to the extent provided
above,  options  may not be  assigned,  transferred,  pledged,  hypothecated  or
disposed of in any way (whether by operation of law or otherwise)  and shall not
be subject to execution,  attachment or similar process,  and any such attempted
assignment,  transfer,  pledge,  hypothecation or disposition  shall be null and
void ab initio and of no force or effect.

            15.         WITHHOLDING  TAXES.  As a  condition  of  exercise of an
Option,  each employee shall, no later than the date of exercise of such option,
pay to the Company in cash or make  arrangements  satisfactory  to the Committee
regarding  payment of any federal,  state or local taxes of any kind required by
law to be withheld  upon the exercise of such  option.  In its  discretion,  the
Committee may provide for the Company's  acceptance or retention of Common Stock
as payment of an  employee's  liability  for tax  required to be withheld by the
Company.

            16.         LEGENDS;  PAYMENT OF  EXPENSES.  The Company may endorse
such legend or legends upon the  certificates  for shares of Common Stock issued
upon  exercise  of an option  under the Plan and may issue such "stop  transfer"
instructions  to its transfer  agent in respect of such shares as it determines,
in its discretion, to be necessary or appropriate to (a) prevent a violation of,
or to perfect an exemption from, the registration requirements of the Securities
Act and any applicable  state  securities  laws, (b) implement the provisions of
the Plan or any  agreement  between the Company and the optionee with respect to
such  shares of Common  Stock,  or (c)  permit  the  Company  to  determine  the
occurrence of a  "disqualifying  disposition," as described in Section 421(b) of
the Code,

                                       -7-






of the shares of Common Stock issued or transferred  upon the exercise of an ISO
granted under the Plan.

            The  Company  shall  pay all  issuance  taxes  with  respect  to the
issuance of shares of Common Stock upon the exercise of an option  granted under
the Plan, as well as all fees and expenses incurred by the Company in connection
with such issuance.

            17.         USE OF  PROCEEDS.  The  cash  proceeds  from the sale of
shares of Common Stock  pursuant to the exercise of options under the Plan shall
be  added  to the  general  funds of the  Company  and  used for such  corporate
purposes as the Board of Directors may determine.

            18.         SUBSTITUTIONS  AND  ASSUMPTIONS  OF  OPTIONS  OF CERTAIN
CONSTITUENT CORPORATIONS. Anything in this Plan to the contrary notwithstanding,
the Board of  Directors  may,  without  further  approval  by the  stockholders,
substitute  new  options  for prior  options of a  Constituent  Corporation  (as
defined  in  Paragraph  19) or assume  the  prior  options  of such  Constituent
Corporation.

            19.         DEFINITIONS.  For  purposes of the Plan,  the  following
terms shall be defined as set forth below:

                        (a)  Constituent  Corporation.   The  term  "Constituent
            Corporation"  shall  mean any  corporation  which  engages  with the
            Company,  any of its  Subsidiaries  or a Parent in a transaction  to
            which  Section  424(a) of the Code  applies  (or would  apply if the
            option  assumed or  substituted  were an ISO),  or any Parent or any
            Subsidiary of such corporation.


                        (b)  Disability.  The  term  "Disability"  shall  mean a
            permanent  and  total  disability  within  the  meaning  of  Section
            22(e)(3) of the Code.

                        (c)    Legal    Representative.    The    term    "Legal
            Representative"  shall  mean the  executor,  administrator  or other
            person who at the time is entitled by law to exercise  the rights of
            a  deceased  or  incapacitated  optionee  with  respect to an option
            granted under the Plan.

                        (d)  Parent.  The  term  "Parent"  shall  have  the same
            definition as "parent corporation" in Section 424(e) of the Code.

                        (e)  Subsidiary.  The term  "Subsidiary"  shall have the
            same definition as "subsidiary corporation" in Section 424(f) of the
            Code.

            20.         GOVERNING LAW;  CONSTRUCTION.  The Plan, such options as
may be granted  hereunder  and all related  matters  shall be  governed  by, and
construed in accordance with, the laws of the State of Delaware,  without regard
to conflict of law provisions.

                                       -8-





            Neither the Plan nor any Contract  shall be construed or interpreted
with any  presumption  against the Company by reason of the Company  causing the
Plan  or  Contract  to  be  drafted.   Whenever  from  the  context  it  appears
appropriate,  any term stated in either the singular or plural shall include the
singular and plural,  and any term stated in the  masculine,  feminine or neuter
gender shall include the masculine, feminine and neuter.

            21.         PARTIAL  INVALIDITY.   The  invalidity,   illegality  or
unenforceability  of any provision in the Plan or any Contract  shall not affect
the validity,  legality or enforceability  of any other provision,  all of which
shall be  valid,  legal and  enforceable  to the  fullest  extent  permitted  by
applicable law.

            22.         STOCKHOLDER  APPROVAL.  The  Plan  shall be  subject  to
approval  by a majority  of the votes  present in person or by proxy at the next
duly held meeting of the Company's stockholders at which a quorum is present. No
options  granted  hereunder may be exercised  prior to such approval;  provided,
however, that the date of grant of any option shall be determined as if the Plan
had not been subject to such approval.  Notwithstanding  the  foregoing,  if the
Plan is not approved by a vote of the  stockholders  of the Company on or before
September 19, 1996, the Plan and any options granted hereunder shall terminate.
