                                VOTING AGREEMENT

     VOTING AGREEMENT (the "Agreement") dated as of August 6, 2003, by and among

Israel   ("Telkoor"),   Mr.  David  Amitai  ("Amitai"),   Mr.  Ben-Zion  Diamant
("Diamant") and Mr. Robert Smith  ("Smith") (each a "Party" and  collectively as
the "Parties")

                              W I T N E S S E T H:

     WHEREAS,  as of the date hereof  Telkoor  owns  2,150,000  shares of Common

     WHEREAS,  as of the date  hereof  Smith  holds  options to  purchase  up to

     WHEREAS,  the Parties  wish to  cooperate  with  respect to the election of
members to the Board of Directors of the Company (the "Directors").

     NOW,  THEREFORE,  the  Parties,  intending  to be legally  bound,  agree as
follows:

1.       Purpose
         -------

     The  object of this  Agreement  is to set  forth  the terms and  conditions
pursuant to which the Parties  shall  cooperate  with respect to the election of
Directors.

2.       Term
         ----

          2.1 This  Agreement  shall come into effect on the date of the signing
     of this Agreement.

          2.2 This  Agreement  shall remain in effect with respect to each Party
     for so long as such Party holds Common Stock, or options  exercisable  into
     Common  Stock,  of the Company,  unless  earlier  terminated  in writing by
     Telkoor and at least two of the other Parties.




3.       Election of the Directors
         -------------------------

     At the meeting of the Company's  shareholders  next held following the date
hereof, and at each subsequent meeting of the Company's  shareholders during the
term of this  Agreement at which  Directors  are  elected,  each Party who holds
shares of the Company on the  applicable  record date for the  relevant  meeting
shall  attend  the  meeting  and vote all of its or his  shares  in the  Company
(including, without limitation, shares that as of the date hereof are underlying
any Equity Securities held by any of the Parties and any other Equity Securities
that may be acquired by such Party prior to such  meeting) in person or by proxy
in favor of the  election  to the  Company's  Board of  Directors  of the  slate
proposed by the Company's Board of Directors.

     For purposes of this Agreement, the term "Equity Securities" shall mean any
securities, now held or hereafter acquired, having voting rights in the election
of the Board of Directors of the Company not  contingent  upon  default,  or any
securities  evidencing an ownership  interest in the Company,  or any securities
convertible  into  or  exercisable  for  any  shares  of the  foregoing,  or any
agreement  or  commitment  to issue  any of the  foregoing,  including,  without
limitation, any stock options or warrants.

4.       Covenants; Further Assurances

     Each Party shall execute and deliver such additional  instruments and other
documents and shall take such further actions as may be necessary or appropriate
to  effectuate,  carry out and comply with all of their  obligations  under this
Agreement.  Without limiting the generality of the foregoing, no Party shall (i)
enter into any agreement or arrangement if such action would  materially  impair
the ability of such Party to effectuate,  carry out or comply with all the terms
of this  Agreement;  or (ii) enter into a voting  agreement  or grant a proxy or
power of attorney  with respect to the Company's  securities  held by such Party
which is inconsistent with this Agreement.

5.       Right of First Refusal

     Each of Amitai, Diamant and Smith (each, an Optionee") agrees as follows:

          5.1  Restrictions  on  Transfer  of  Shares  by  Optionees.  Except as
     otherwise  provided in this Agreement,  an Optionees will not sell, assign,
     transfer, pledge,  hypothecate,  or otherwise encumber or dispose of in any
     way,  all or any part of or any  interest in the Equity  Securities  now or
     hereafter owned or held by such Optionee. Any sale,  assignment,  transfer,
     pledge, hypothecation or other encumbrance or disposition (a "Transfer") of
     Equi1y Securities not made in conformance with this Agreement shall be null
     and void.

          5.2 Transfer Notice.  If at any time any Optionee proposes to Transfer
     any Equity  Securities,  then the  Optionee  shall  give  Telkoor a written
     notice of the  Optionee's  intention  to make the Transfer  (the  "Transfer
     Notice"),  which  Transfer  Notice shall include (i) a  description  of the
     Equity  Securities  to be  transferred  ("Offered  Shares")  and  (ii)  the
     consideration and the material terms and conditions upon which the proposed
     Transfer is to be made, including the market price.


          5.3  Telkoor's  Option.  Telkoor  shall have an option for a period of
     three (3) days from receipt of the Transfer Notice to elect to purchase the
     Offered Shares at the same price and subject to the same material terms and
     conditions as described in the Transfer  Notice.  Telkoor may exercise such
     purchase  option and,  thereby,  purchase all (or a portion of) the Offered
     Shares by notifying the Optionee in writing  before  expiration of the such
     three (3) day  period as to the  number of such  shares  which it wishes to
     purchase.  If Telkoor gives the Optionee notice that it desires to purchase
     such shares,  then payment for the Offered Shares shall be by check or wire
     transfer, against delivery of the Offered Shares to be purchased at a place
     agreed upon  between the parties and at the time of the  scheduled  closing
     therefor,  which  shall be no later  than  forty-five  (45) days  after the
     Telkoor's  receipt  of the  Transfer  Notice,  unless the  Transfer  Notice
     contemplated a later closing.

          5.4 If Telkoor  declines to purchase all, or a portion of, the Offered
     Shares,  the Offered Shares which Telkoor has declined to purchase shall be
     freely tradable (i.e., shall not be subject to the transfer limitations set
     forth in this Section 5), subject to the provisions of any applicable  law.
     If the market price declines at the end of this 3 day period,  Telkoor will
     compensate the Optionee for the difference.
