                                   FORM OF

                        WARRANT TO PURCHASE COMMON STOCK

                       VOID AFTER 5:30 P.M., NEW YORK CITY
                          TIME, ON THE EXPIRATION DATE

THIS WARRANT AND ANY SHARES  ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE NOT
BEEN  REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),  AND
MAY NOT BE SOLD, PLEDGED, HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED WITHOUT
COMPLIANCE  WITH THE  REGISTRATION  OR  QUALIFICATION  PROVISIONS  OF APPLICABLE
FEDERAL AND STATE SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

         FOR VALUE RECEIVED, NAI TECHNOLOGIES, INC., a New York corporation (the
"Company"),  hereby  agrees  to  sell  upon  the  terms  and on  the  conditions
hereinafter  set forth,  but no later than 5:30 p.m., New York City time, on the
Expiration  Date  (as  hereinafter   defined)  to   ______________________,   or
registered  assigns (the  "Holder"),  under the terms as hereinafter  set forth,
_____________________  (__________) fully paid and non-assessable  shares of the
Company's  Common Stock,  par value $.10 per share (the "Warrant  Stock"),  at a
purchase  price  per  share of Two and  50/100  Dollars  ($2.50)  (the  "Warrant
Price"),  pursuant to this  warrant  (this  "Warrant").  The number of shares of
Warrant Stock to be so issued and the Warrant Price are subject to adjustment in
certain  events as  hereinafter  set forth.  The term "Common Stock" shall mean,
when used herein,  unless the context  otherwise  requires,  the stock and other
securities  and  property  at the  time  receivable  upon the  exercise  of this
Warrant.

         This Warrant is one of a series of the  Company's  Warrants to purchase
Common Stock  (collectively,  the  "Warrants"),  issued pursuant to that certain
Confidential  Private  Placement   Memorandum,   dated  December  15,  1995,  as
supplemented  (the  "Memorandum").  Capitalized  terms  used  and not  otherwise
defined herein shall have the respective  meanings attributed thereto in Section
10.

         1. Exercise of Warrant.

         (a) The Holder may  exercise  this  Warrant  according  to its terms by
surrendering this Warrant to the Company at the address set forth in Section 11,
the  subscription  form  attached  hereto  having then been duly executed by the
Holder,  accompanied  by cash,  certified  check or bank draft in payment of the
purchase price, in lawful money of the United







States of America,  for the number of shares of the Warrant  Stock  specified in
the  subscription  form, or as otherwise  provided in this Warrant prior to 5:30
p.m., New York City time, on February 15, 2002 (the "Expiration Date").

         (b) This  Warrant may be  exercised  in whole or in part so long as any
exercise in part hereof would not involve the issuance of  fractional  shares of
Warrant  Stock.  If exercised in part, the Company shall deliver to the Holder a
new Warrant,  identical in form, in the name of the Holder, evidencing the right
to purchase  the number of shares of Warrant  Stock as to which this Warrant has
not been exercised,  which new Warrant shall be signed by the Chairman and Chief
Executive Officer or the President and the Secretary or the Assistant  Secretary
of the Company.  The term Warrant as used herein  shall  include any  subsequent
Warrant issued as provided herein.

         (c) No fractional shares or scrip representing  fractional shares shall
be issued upon the exercise of this Warrant.  The Company shall pay cash in lieu
of fractions  with  respect to the Warrants  based upon the fair market value of
such fractional shares of Common Stock (which shall be the closing price of such
shares on the  exchange or market on which the Common  Stock is then  traded) at
the time of exercise of this Warrant.

         (d) In the event of any  exercise  of the  rights  represented  by this
Warrant,  a  certificate  or  certificates  for the Warrant  Stock so purchased,
registered in the name of the Holder,  shall be delivered to the Holder within a
reasonable  time after such rights shall have been so  exercised.  The person or
entity in whose  name any  certificate  for the  Warrant  Stock is  issued  upon
exercise of the rights  represented  by this  Warrant  shall for all purposes be
deemed to have become the holder of record of such shares  immediately  prior to
the close of  business  on the date on which the  Warrant  was  surrendered  and
payment of the Warrant Price and any applicable taxes was made,  irrespective of
the date of  delivery  of such  certificate,  except  that,  if the date of such
surrender and payment is a date when the stock transfer books of the Company are
closed,  such person shall be deemed to have become the holder of such shares at
the opening of business on the next  succeeding date on which the stock transfer
books are open.  Except as provided in Section 4 hereof,  the Company  shall pay
any and all  documentary  stamp or similar  issue or transfer  taxes  payable in
respect of the issue or delivery  of shares of Common  Stock on exercise of this
Warrant.

         2. Disposition of Warrant Stock and Warrant.

         (a) The Holder  hereby  acknowledges  that this Warrant and any Warrant
Stock purchased  pursuant  hereto are not being  registered (i) under the Act on
the ground that the issuance of this Warrant is exempt from  registration  under
Section 4(2) of the Act as not involving  any public  offering or (ii) under any
applicable  state  securities  law because the issuance of this Warrant does not
involve any public offering; and that the Company's reliance on the Section 4(2)
exemption of the Act and under applicable state securities laws is predicated in
part on the representations  hereby made to the Company by the Holder that it is
acquiring this Warrant and will acquire the Warrant Stock for investment for its
own account, with no present

                                        2







intention  of dividing its  participation  with others or reselling or otherwise
distributing the same, subject, nevertheless, to any requirement of law that the
disposition of its property shall at all times be within its control.

         The Holder  hereby  agrees that it will not sell or transfer all or any
part of this Warrant  and/or  Warrant Stock unless and until it shall first have
given notice to the Company  describing  such sale or transfer and  furnished to
the Company either (i) an opinion,  reasonably  satisfactory  to counsel for the
Company, of counsel (skilled in securities  matters,  selected by the Holder and
reasonably  satisfactory to the Company) to the effect that the proposed sale or
transfer may be made without registration under the Act and without registration
or qualification under any state law, or (ii) an interpretative  letter from the
Securities and Exchange Commission to the effect that no enforcement action will
be  recommended  if the proposed  sale or transfer is made without  registration
under the Act.

         (b) If, at the time of issuance of the shares issuable upon exercise of
this Warrant, no registration statement is in effect with respect to such shares
under applicable  provisions of the Act, the Company may at its election require
that the Holder provide the Company with written  reconfirmation of the Holder's
investment  intent and that any stock  certificate  delivered to the Holder of a
surrendered Warrant shall bear legends reading substantially as follows:

                  "TRANSFER OF THE SHARES  REPRESENTED  BY THIS  CERTIFICATE  IS
                  SUBJECT  TO  CERTAIN  RESTRICTIONS  SET  FORTH IN THE  WARRANT
                  PURSUANT  TO  WHICH  THESE  SHARES  WERE  PURCHASED  FROM  THE
                  COMPANY.  COPIES  OF  THOSE  RESTRICTIONS  ARE ON  FILE AT THE
                  PRINCIPAL  OFFICES OF THE  COMPANY,  AND NO  TRANSFER  OF SUCH
                  SHARES  OR OF THIS  CERTIFICATE,  OR OF ANY  SHARES  OR  OTHER
                  SECURITIES (OR  CERTIFICATES  THEREFOR) ISSUED IN EXCHANGE FOR
                  OR IN RESPECT OF SUCH SHARES,  SHALL BE  EFFECTIVE  UNLESS AND
                  UNTIL THE TERMS AND  CONDITIONS  THEREIN  SET FORTH SHALL HAVE
                  BEEN COMPLIED WITH."

                  "THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  HAVE NOT BEEN
                  REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AND MAY NOT BE
                  SOLD,  TRANSFERRED,  PLEDGED OR  OTHERWISE  DISPOSED OF IN THE
                  ABSENCE  OF AN  EFFECTIVE  REGISTRATION  STATEMENT  UNDER  THE
                  SECURITIES  ACT OF 1933 OR AN OPINION OF COUNSEL  SATISFACTORY
                  TO THE ISSUER OF THIS  CERTIFICATE  THAT  REGISTRATION  IS NOT
                  REQUIRED UNDER SAID ACT."

                                        3








In addition, so long as the foregoing legend may remain on any stock certificate
delivered to the Holder,  the Company may maintain  appropriate  "stop transfer"
orders with respect to such certificates and the shares  represented  thereby on
its books and  records  and with  those to whom it may  delegate  registrar  and
transfer functions.

         3.  Reservation of Shares.  The Company hereby agrees that at all times
there shall be reserved  for  issuance  upon the  exercise of this  Warrant such
number of shares of its Common  Stock as shall be  required  for  issuance  upon
exercise of this Warrant.  The Company  further agrees that all shares which may
be issued upon the  exercise of the rights  represented  by this Warrant will be
duly  authorized  and will,  upon  issuance and against  payment of the exercise
price, be validly issued,  fully paid and  non-assessable,  free from all taxes,
liens, charges and preemptive rights with respect to the issuance thereof, other
than taxes, if any, in respect of any transfer occurring  contemporaneously with
such issuance and other than transfer  restrictions imposed by federal and state
securities laws.

         4. Exchange,  Transfer,  Assignment or Loss of Warrant. This Warrant is
exchangeable,  without expense,  at the option of the Holder,  upon presentation
and  surrender  hereof to the  Company  or at the  office of its stock  transfer
agent,  if any, for other  Warrants of different  denominations,  entitling  the
Holder or Holders thereof to purchase in the aggregate the same number of shares
of Common Stock  purchasable  hereunder.  Upon  surrender of this Warrant to the
Company  or at the  office  of its  stock  transfer  agent,  if  any,  with  the
Assignment  Form annexed  hereto duly  executed and funds  sufficient to pay any
transfer  tax,  the Company  shall,  without  charge,  execute and deliver a new
Warrant in the name of the assignee  named in such  instrument of assignment and
this Warrant shall promptly be canceled. This Warrant may be divided or combined
with other Warrants that carry the same rights upon  presentation  hereof at the
office of the  Company or at the  office of its stock  transfer  agent,  if any,
together with a written notice  specifying the names and  denominations in which
new Warrants are to be issued and signed by the Holder hereof.

         5.  Capital  Adjustments.  This  Warrant is  subject  to the  following
further provisions:

          (a)   Recapitalization,   Reclassification  and  Succession.   If  any
     recapitalization  of the Company or reclassification of its Common Stock or
     any merger or  consolidation  of the Company into or with a corporation  or
     other business entity,  or the sale or transfer of all or substantially all
     of the  Company's  assets or of any successor  corporation's  assets to any
     other  corporation  or  business  entity  (any  such  corporation  or other
     business  entity being included  within the meaning of the term  "successor
     corporation")  shall be effected,  at any time while this  Warrant  remains
     outstanding and unexpired,  then, as a condition of such  recapitalization,
     reclassification,  merger,  consolidation,  sale or  transfer,  lawful  and
     adequate  provision  shall  be made  whereby  the  Holder  of this  Warrant
     thereafter  shall have the right to  receive  upon the  exercise  hereof as
     provided in Section 1 and in lieu of the shares of Common Stock immediately
     theretofore  issuable  upon the  exercise of this  Warrant,  such shares of
     capital  stock,  securities  or other  property as may be issued or payable
     with respect to or in exchange

                                        4







     for a number of  outstanding  shares of Common Stock equal to the number of
     shares of Common Stock immediately  theretofore  issuable upon the exercise
     of  this  Warrant  had  such  recapitalization,  reclassification,  merger,
     consolidation, sale or transfer not taken place, and in each such case, the
     terms of this Warrant  shall be  applicable to the shares of stock or other
     securities or property  receivable  upon the exercise of this Warrant after
     such consummation.

          (b)  Subdivision or Combination of Shares.  If the Company at any time
     while this Warrant  remains  outstanding  and unexpired  shall subdivide or
     combine its Common Stock, the number of shares of Warrant Stock purchasable
     upon   exercise  of  this   Warrant   and  the   Warrant   Price  shall  be
     proportionately adjusted.

          (c) Stock  Dividends  and  Distributions.  If the  Company at any time
     while this  Warrant is  outstanding  and  unexpired  shall issue or pay the
     holders of its Common Stock,  or take a record of the holders of its Common
     Stock for the purpose of entitling them to receive,  a dividend payable in,
     or other distribution of, Common Stock, then (i) the Warrant Price shall be
     adjusted in  accordance  with Section 5(e) and (ii) the number of shares of
     Warrant Stock  purchasable  upon exercise of this Warrant shall be adjusted
     to the  number of shares of Common  Stock  that  Holder  would  have  owned
     immediately   following   such  action  had  this  Warrant  been  exercised
     immediately prior thereto.

          (d) Stock and Rights  Offering to  Shareholders.  If at any time after
     the date of issuance of this  Warrant,  the Company shall issue or sell, or
     fix a record date for the purposes of entitling holders of its Common Stock
     to receive, (i) Common Stock or (ii) rights,  options or warrants entitling
     the  holders  thereof  to  subscribe  for  or  purchase  Common  Stock  (or
     securities  convertible  or  exchangeable  into or  exercisable  for Common
     Stock),  in any such case,  at a price per share (or  having a  conversion,
     exchange or exercise  price per share) that is less than the closing  price
     per  share  of  the  Company's  Common  Stock  on  the  principal  national
     securities  exchange  on which the Common  Stock is listed or  admitted  to
     trading or, if not listed or traded on any such  exchange,  on the National
     Market System (the "National Market System") of the National Association of
     Securities Dealers Automated Quotations System ("Nasdaq"), or if not listed
     or traded on any such exchange or system,  the average of the bid and asked
     price per share on Nasdaq or, if such  quotations  are not  available,  the
     fair market value per share of the  Company's  Common  Stock as  reasonably
     determined by the Board of Directors of the Company (the  "Closing  Price")
     on the  date  of  such  issuance  or sale  or on  such  record  date  then,
     immediately after the date of such issuance or sale or on such record date,
     (x) the Warrant  Price shall be adjusted in  accordance  with Section 5(e),
     and (y) the number of shares of Warrant Stock  purchasable upon exercise of
     this Warrant shall be adjusted to that number determined by multiplying the
     number of shares of Warrant Stock purchasable upon exercise of this Warrant
     immediately before the date of such issuance or sale or such record date by
     a fraction, the denominator of which will be the number of shares of Common
     Stock  outstanding  on such date plus the number of shares of Common  Stock
     that the aggregate  offering price of the total number of shares so offered
     for subscription or purchase (or the aggregate  initial  conversion  price,
     exchange  price  or  exercise  price  of  the  convertible   securities  or
     exchangeable securities or rights, options or warrants, as the case may be,
     so offered) would purchase at such Closing Price, and

                                        5







     the  numerator  of which  will be the  number of  shares  of  Common  Stock
     outstanding  on such date plus the  number of  additional  shares of Common
     Stock offered for  subscription  or purchase (or into which the convertible
     or  exchangeable  securities or rights,  options or warrants so offered are
     initially convertible or exchangeable or exercisable, as the case may be).

          If the  Company  shall at any time after the date of  issuance of this
     Warrant distribute to all holders of its Common Stock any shares of capital
     stock  of the  Company  (other  than  Common  Stock)  or  evidences  of its
     indebtedness or assets (excluding cash dividends or distributions paid from
     retained  earnings  or  current  year's  or prior  year's  earnings  of the
     Company)  or rights or  warrants to  subscribe  for or purchase  any of its
     securities  (excluding  those  referred  to in  the  immediately  preceding
     paragraph) (any of the foregoing being hereinafter in this paragraph called
     the "Securities"), then in each such case, the Company shall reserve shares
     or other  units of such  securities  for  distribution  to the Holder  upon
     exercise of this  Warrant so that,  in addition to the shares of the Common
     Stock to which such Holder is entitled,  such Holder will receive upon such
     exercise  the amount and kind of such  Securities  which such Holder  would
     have received if the Holder had,  immediately  prior to the record date for
     the distribution of the Securities, exercised this Warrant.

          (e) Warrant Price Adjustment. Whenever the number of shares of Warrant
     Stock  purchasable  upon  exercise of this Warrant is  adjusted,  as herein
     provided, the Warrant Price payable upon the exercise of this Warrant shall
     be adjusted  to that price  determined  by  multiplying  the Warrant  Price
     immediately  prior to such  adjustment  by a fraction (i) the  numerator of
     which  shall be the  number of shares of  Warrant  Stock  purchasable  upon
     exercise of this Warrant immediately prior to such adjustment, and (ii) the
     denominator  of which  shall be the  number  of  shares  of  Warrant  Stock
     purchasable upon exercise of this Warrant immediately thereafter.

          (f) 1996 EBITDA  Adjustment.  The Warrant Price shall  additionally be
     adjusted in the following circumstances:

               (i) if the  Company  shall  achieve  1996 EBITDA (as such term is
          defined  in  Section  10) in an amount of less  than  $6,000,000,  the
          Warrant Price shall be reduced to $2.00 per share; and

               (ii) if the  Company  shall  achieve  1996 EBITDA in an amount of
          less than $4,750,000  (together with the $6,000,000 amount referred to
          above, the "Adjusted Amounts"),  the Warrant Price shall be reduced to
          $1.50 per share;

     provided,  however,  that in the event the Company sells all of the capital
     stock  or all or  substantially  all of the  assets  of one or  more of its
     Subsidiaries in 1996, the Adjusted  Amounts for 1996 will be reduced by the
     amount  or  amounts  set  forth in  Schedule  A hereto  in  respect  of the
     Subsidiary or Subsidiaries  so involved.  In the event any such sale occurs
     during 1996, the applicable  Adjusted Amount will be reduced by multiplying
     it by a fraction, the numerator of

                                        6







     which is the number of days of the year  remaining  after any such sale and
     the denominator is 365.

          (g)  Certain  Shares  Excluded.  The number of shares of Common  Stock
     outstanding at any given time for purposes of the  adjustments set forth in
     this Section 5 shall exclude any shares then directly or indirectly held in
     the treasury of the Company.

          (h) Deferral and  Cumulation  of De Minimis  Adjustments.  The Company
     shall not be required to make any adjustment  pursuant to this Section 5 if
     the amount of such  adjustment  would be less than one percent  (1%) of the
     Warrant Price in effect  immediately  before the event that would otherwise
     have given rise to such adjustment.  In such case, however,  any adjustment
     that would  otherwise  have been  required  to be made shall be made at the
     time of and together with the next subsequent  adjustment  which,  together
     with any adjustment or adjustments so carried forward,  shall amount to not
     less than one  percent  (1%) of the  Warrant  Price in  effect  immediately
     before the event giving rise to such next subsequent adjustment.

          (i) Duration of Adjustment. Following each computation or readjustment
     as provided in this Section 5, the new adjusted Warrant Price and number of
     shares of Warrant  Stock  purchasable  upon  exercise of this Warrant shall
     remain in effect until a further  computation  or  readjustment  thereof is
     required.

         6. Notice to Holders.

         (a) Notice of Record Date. In case:

          (i) the Company shall take a record of the holders of its Common Stock
     (or other stock or securities at the time  receivable  upon the exercise of
     this  Warrant)  for the purpose of  entitling  them to receive any dividend
     (other than a cash dividend  payable out of earned  surplus of the Company)
     or other distribution, or any right to subscribe for or purchase any shares
     of stock of any  class or any other  securities,  or to  receive  any other
     right;

          (ii)   of   any   capital   reorganization   of   the   Company,   any
     reclassification  of the capital  stock of the Company,  any  consolidation
     with or merger of the Company into another  corporation,  or any conveyance
     of all  or  substantially  all of the  assets  of the  Company  to  another
     corporation; or

          (iii) of any voluntary  dissolution,  liquidation or winding-up of the
     Company;

then,  and in each such case, the Company will mail or cause to be mailed to the
Holder hereof at the time outstanding a notice  specifying,  as the case may be,
(i) the date on which a record is to be taken for the purpose of such  dividend,
distribution or right, and stating the amount and

                                        7







character of such  dividend,  distribution  or right,  or (ii) the date on which
such  reorganization,   reclassification,   consolidation,  merger,  conveyance,
dissolution,  liquidation or winding-up is to take place,  and the time, if any,
is to be fixed, as of which the holders of record of Common Stock (or such stock
or securities at the time receivable upon the exercise of this Warrant) shall be
entitled  to  exchange  their  shares of Common  Stock (or such  other  stock or
securities)   for   securities   or  other   property   deliverable   upon  such
reorganization, reclassification, consolidation, merger, conveyance, dissolution
or  winding-up.  Such notice  shall be mailed at least thirty (30) days prior to
the  record  date  therein  specified,  or if no  record  date  shall  have been
specified therein, at least thirty (30) days prior to such specified date.

         (b)  Certificate of Adjustment.  Whenever any adjustment  shall be made
pursuant to Section 5 hereof,  the Company  shall  promptly  make a  certificate
signed by its  Chairman and Chief  Executive  Officer,  its  President or a Vice
President  and by its  Treasurer  or  Assistant  Treasurer  or its  Secretary or
Assistant Secretary,  setting forth in reasonable detail the event requiring the
adjustment,  the amount of the  adjustment,  the method by which such adjustment
was  calculated  and the  Warrant  Price and number of shares of  Warrant  Stock
purchasable   upon  exercise  of  this  Warrant  after  giving  effect  to  such
adjustment,  and shall promptly cause copies of such  certificates  to be mailed
(by first class mail, postage prepaid) to the Holder of this Warrant.

         7. Loss, Theft, Destruction or Mutilation.  Upon receipt by the Company
of evidence satisfactory to it, in the exercise of its reasonable discretion, of
the ownership  and the loss,  theft,  destruction  or mutilation of this Warrant
and,  in the  case of  loss,  theft  or  destruction,  of  indemnity  reasonably
satisfactory  to the Company and, in the case of mutilation,  upon surrender and
cancellation  thereof,  the Company  will  execute and deliver in lieu  thereof,
without  expense to the  Holder,  a new  Warrant  of like  tenor  dated the date
hereof.

         8. Warrant  Holder Not a  Shareholder.  The Holder of this Warrant,  as
such,  shall not be entitled by reason of this Warrant to any rights  whatsoever
as a shareholder of the Company.

         9.  Registration  Rights.  This  Warrant and the shares of Common Stock
issuable upon exercise of this Warrant will be accorded the registration  rights
under the Act set forth in that certain  Registration  Rights Agreement  between
the  Company  and the  Holders,  a form of which  agreement  is being  furnished
concurrently herewith.

         10. Definitions. As used herein, unless the context otherwise requires,
the following terms have the respective meanings:

          (a) "Affiliate":  with respect to any Person,  the following:  (i) any
     other Person that at such time directly or  indirectly  through one or more
     intermediaries  controls,  or is controlled  by or is under common  control
     with such first Person or (ii) any Person  beneficially  owning or holding,
     directly  or  indirectly,  10% or more of any  class of  voting  or  equity
     interests of the Company or any Subsidiary or any  corporation of which the
     Company and
