Item 5.  Other Events.

         On February 15, 1996 and  February 23, 1996, NAI  Technologies,  Inc.,
a  New  York  corporation  (the "Registrant"),  sold  in  a private offering an
aggregate  of  7,995  units  (the "Units"),  each  Unit  consisting  of  $1,000
principal  amount  of the Registrant's 12% Convertible Subordinated  Promissory
Notes  due  2001  (the  "Notes")  and a  detachable  warrant (the "Warrant") to
purchase  the  Registrant's  common  stock,  par  value  $.10 per  share   (the
"Common  Stock"),  at  a  purchase  price of $1,000 per Unit,  for an aggregate
purchase price of $7,995,000 to selected  qualified  investors  (the "Investment
Transaction").


         The net  proceeds  realized  by the  Registrant  from  the  sale of the
securities, after the payment of fees and expenses associated with the offering,
including a placement  fee, are estimated to be  approximately  $6,860,000.  The
Registrant  intends to use a portion of the net proceeds to pay amounts past due
to vendors primarily for raw materials and components.  The balance will be used
for general corporate  purposes  including payments due to the Registrant's bank
lenders during 1996 pursuant to the revised credit  agreement  discussed  below.

         Assuming the conversion of all the  Notes and  the  exercise of all the
Warrants as well as the exercise of all compensatory warrants, the  Company will
have  received gross proceeds of approximately  $18,000,000 in exchange  for the
sale of approximately 49.6% of the  shares of Common Stock  on  a  fully-diluted
basis  and based on shares currently outstanding.


THE NOTES

         The Notes will mature on January 15, 2001 and will bear  interest  from
the date of issuance at the rate per annum of 12%. Interest on the Notes will be
payable  quarterly in arrears on January 15, April 15, July 15 and October 15 of
each year  commencing  April 15, 1996. In the event of a Chapter 11 or Chapter 7
bankruptcy  case in which the  Registrant  is the  debtor,  the Notes  will bear
interest from the date

                                       -2-

<PAGE>
<PAGE>



of  commencement  of the case at a default rate per annum equal to the lesser of
18% or the  highest  such rate  allowable  by law.  The Notes will be subject to
prepayment,  in whole and not in part, at the option of the  Registrant,  at any
time after the third  anniversary  of the date of issuance,  without  premium or
penalty.  Upon the occurrence of a "change in control" of the  Registrant,  each
holder of the Notes will have the right to require the  Registrant to repurchase
such holder's Notes in whole and not in part,  without premium or penalty,  at a
purchase  price  in cash in an  amount  equal  to 100% of the  principal  amount
thereof,  together  with  accrued  and unpaid  interest,  if any, to the date of
purchase,  pursuant to an offer made in accordance with the procedures described
in the Notes.  The Notes may not be amended in any material  respect without the
consent  of the  holders  of at  least  50% in  aggregate  principal  amount  of
outstanding Notes.

         The  indebtedness  evidenced  by  the  Notes,  including  any  interest
thereon,  is  subordinate  and subject in right of payment to the prior  payment
when due in full of all Senior  Indebtedness.  Senior Indebtedness is defined in
the Note to include,  unless the terms respecting the particular indebtedness or
obligation  otherwise  provide,  the  principal  of,  premium,  if any,  and any
interest on, all  liabilities of the  Registrant,  direct or contingent,  joint,
several or independent, now or hereafter existing, due or to become due, whether
created directly or acquired by assignment or otherwise,  under or in respect of
the Amended and Restated Credit Agreement dated as of April 12, 1995, as amended
to date (the "Credit  Agreement"),  among the Registrant,  Chemical Bank and The
Bank of New  York  (collectively,  the  "Bank  Lenders"),  and  all  extensions,
renewals  and  refunding  of any  of the  foregoing  up to the  original  amount
(including the revised Credit Agreement discussed below). At February 15,

                                       -3-

<PAGE>
<PAGE>



1996, the amount of Senior Indebtedness outstanding was $15,975,000.  There will
be no sinking fund for the Notes.

         The Notes may be converted by the holders as to their principal  amount
into Common Stock of the  Registrant at any time at a conversion  price equal to
$2.00 per share,  subject to adjustment.  The conversion price of the Notes will
be adjusted to $1.50 or $1.00, respectively, if earnings before interest, taxes,
depreciation  and   amortization  of  the  Registrant   ("EBITDA")  falls  below
$6,000,000 or $4,750,000 in 1996. Should the Registrant sell the stock or assets
of a subsidiary in 1996, such amounts will be reduced by certain agreed amounts,
depending on the time of sale. The conversion  price and the number of shares of
Common Stock to be received upon  conversion are subject to adjustment  upon the
occurrence  of any of the  following  events:  (i) the  recapitalization  of the
Registrant or  reclassification of the securities to be received upon conversion
or any merger or  consolidation  of the Registrant into or with a corporation or
other business entity,  or the sale or transfer of all or  substantially  all of
the  Registrant's  assets  or any  successor  corporation's  assets to any other
corporation  or business  entity,  (ii) the  subdivision  or  combination of the
shares of Common  Stock to be  received  upon  conversion,  (iii) the payment of
dividends or other  distributions  in the form of the  securities to be received
upon  conversion,  and (iv) the  issuance of shares of Common Stock at less than
the conversion  price.  No adjustment of the conversion  price is required to be
made until cumulative  adjustments otherwise required to be made amount to 1% or
more of the conversion price last adjusted.  The Registrant may force conversion
of the Notes if, at any time prior to  maturity,  the  closing bid price for the
Common Stock  exceeds $6.00 per share for thirty (30)  consecutive  trading days
prior to the giving of notice of

                                       -4-

<PAGE>
<PAGE>



conversion.  Fractional  shares will not be issued upon  conversion,  but a cash
adjustment  will be paid in lieu  thereof.  Interest  will  accrue  on the Notes
through  the date of  conversion.  No  payment  or  adjustment  will be made for
dividends on securities issued upon conversion.

         The Notes contain certain negative covenants  prohibiting,  among other
things, the negative pledge of the Registrant's assets not otherwise  encumbered
by its senior lenders.

         "Events of Default" under the Notes include failure to pay principal or
interest,  the failure to pay other indebtedness for borrowed money in excess of
$500,000 when due, or the acceleration of such indebtedness,  the failure to pay
any  judgment  in  excess of  $500,000  when due or  stayed,  and  voluntary  or
involuntary  bankruptcy of the Registrant.  In the event the Registrant defaults
in making  any  payment  of  principal  required  to be made by the  Notes,  the
Registrant shall pay interest on such defaulted amount at a rate of 18%.

         If an Event of Default occurs and is continuing, then and in every such
case the  holders  of the Notes may  declare  the Notes then  outstanding  to be
immediately due and payable by a notice in writing to the Registrant,  whereupon
the same will be immediately  due and payable.  A payment default will result in
an  increased  issuance to investors of Warrants to purchase an amount of shares
of Common Stock and until the Notes are fully repaid, the right of the investors
to elect a majority of the  Registrant's  Board of Directors.  In the event of a
Chapter 11 or Chapter 7 bankruptcy  case in which the  Registrant is the debtor,
the Notes  will bear  interest  from the date of  commencement  of the case at a
default  rate per  annum  equal to the  lesser of 18% or the  highest  such rate
allowable by law.

         The foregoing  description  of the Notes is a summary of certain of the
provisions  contained in the Notes and  reference is made to a form of the Notes
which is attached  hereto as Exhibit 1 and is  incorporated  herein by reference
for all of its terms and conditions.

THE WARRANTS

         Each Warrant entitles the holder thereof to purchase  specified numbers
of shares of Common Stock at an exercise price equal to $2.50 per share, subject
to adjustment (the "Exercise Price"). The Exercise Price of the Warrants will be
adjusted to $2.00 or $1.50, respectively, if the Registrant's EBITDA falls below
$6,000,000 or $4,750,000 in 1996. Should the Registrant sell the stock or assets
of a subsidiary in 1996,  such amounts will be reduced by certain agreed amounts
depending on the time of sale.  The  Exercise  Price and the number of shares of
Common Stock to be received  upon  exercise are subject to  adjustment  upon the
occurrence  of any of the  following  events:  (i) the  recapitalization  of the
Registrant or  reclassification of the securities to be received upon conversion
or any merger or  consolidation  of the Registrant into or with a corporation or
other business entity,  or the sale or transfer of all or  substantially  all of
the  Registrant's  assets  or any  successor  corporation's  assets to any other
corporation or business entity, (ii) the subdivision or combination of shares of
Common  Stock to be received  upon  exercise,  (iii) the payment of dividends or
other  distributions in the form of the securities to be received upon exercise,
and (iv) the issuance of shares of Common Stock at less than the Exercise Price.
No  adjustment  of the  Exercise  Price is required to be made until  cumulative
adjustments  otherwise  required to be made amount to 1% or more of the Exercise
Price last adjusted. Warrants will be exercisable, at any time and from time

                                       -6-

to time, on or before 5:30 p.m.,  local time, on or before February 15, 2002, by
delivery of an exercise  notice duly  completed  and  tendering of the aggregate
Exercise Price.

         The  foregoing  description  of the Warrants is a summary of certain of
the  provisions  contained in the Warrants and  reference is made to the form of
the Warrants which is attached hereto as Exhibit 2 and is incorporated herein by
reference for all of its terms and conditions.

SHAREHOLDER APPROVAL

         The  sale  of the  Units  offered  in the  Investment  Transaction  was
conditioned  on  shareholder  approval  of: (i) the  issuance of the Units which
would  result in the  potential  issuance  of more than 20% of the  Registrant's
Common Stock and may result in a change of control of the  Registrant,  and (ii)
an amendment to the  Registrant's  Certificate of  Incorporation to increase the
number of authorized  shares of Common Stock from  10,000,000 to 25,000,000 (the
"Charter   Amendment").   Both  matters  were   approved  by  the   Registrant's
shareholders at a Special Meeting of Shareholders held in Longmont,  Colorado on
February 1, 1996.

         The  foregoing  description  of the Charter  Amendment  is a summary of
certain of the  provisions  contained in the Charter  Amendment and reference is
made to a copy of such Charter  Amendment  which is attached hereto as Exhibit 3
and is incorporated herein by reference for all of its terms and conditions.

REGISTRATION RIGHTS

         As part of the Investment Transaction the Registrant has agreed to file
a  registration  statement  with the  Securities  and Exchange  Commission  (the
"Commission") with respect to the Notes, the Warrants and the shares of Common

                                       -7-


<PAGE>
<PAGE>



Stock  reserved for issuance  upon  conversion  of the Notes and exercise of the
Warrants  (collectively,  the "Registrable  Securities")  within the later of 90
days after the initial closing on February 14, 1996 or March 31, 1996 and to use
its best efforts to cause such registration statement to become effective within
60 days thereafter and to keep such registration  statement  effective for up to
three years  thereafter in accordance with a Registration  Rights Agreement (the
"Registration Rights Agreement"). In the event the registration statement is not
filed or declared effective and does not remain effective for such required time
periods,  the interest rate borne by the Notes will be increased by 1% per annum
for each 90-day period (or portion  thereof) that such failure  continues,  with
such rate to increase to 18% if such failure  continues  for nine months or more
after the initial  closing,  provided  that the interest rate borne by the Notes
will  not be  increased  if the  Registrable  Securities  are  otherwise  freely
tradeable  pursuant  to Rule  144  promulgated  under  the  Securities  Act,  or
otherwise.  Upon  the  effectiveness  or  reeffectiveness  of  the  registration
statement,  the interest rate borne by the Notes will be reduced to the original
interest rate of the Notes.

         The Registrant has also agreed to include the  Registerable  Securities
in any  registration  statement filed with the Commission,  at any time prior to
December 31, 2005, with respect to any future public offerings  initiated by the
Registrant  or any other  selling  shareholders  (the  "Piggy-Back  Rights") and
holders of a majority  in  interest  of  Registerable  Securities  will have the
right,  which right may be exercised no more than twice, to demand,  at any time
prior to December 31, 2005,  that the Registrant  file a registration  statement
with the Commission  with respect to not less than $1,000,000 of the Registrable
Securities (the "Demand Rights"). The Bank

                                       -8-

<PAGE>



Lenders will have  priority  with respect to the sale of an aggregate of 250,000
shares of Common Stock owned by them in up to two of such  registrations so long
as any Senior  Indebtedness  remains  outstanding.  The Registrant will bear all
fees and expenses  incurred in the  preparation  and filing of any  registration
statement  relating to the exercise of Piggy-Back  Rights and the first exercise
of Demand Rights as well as the initial registration.

         The foregoing  description of the  Registration  Rights  Agreement is a
summary  of certain  of the  provisions  contained  in the  Registration  Rights
Agreement  and reference is made to the form of such agreement which is attached
hereto as Exhibit 4 and is incorporated herein by reference for all of its terms
and conditions.

PLACEMENT AGENCY AGREEMENT

         Pursuant to the Investment  Transaction  the Registrant  entered into a
Placement Agency Agreement, dated as of December 15, 1995 (the "Placement Agency
Agreement"),  with Commonwealth  Associates  ("Commonwealth")  whereby the Units
were  offered  on behalf of the  Registrant  solely by  Commonwealth  on a "best
efforts -- 6,000 Units or none" basis.  Commonwealth has received a fee equal to
8% of the gross  proceeds of the offering  together  with the  reimbursement  of
accountable expenses up to $200,000 for its services. Under the Placement Agency
Agreement,  until  December 31, 2000,  Commonwealth  has been granted a right of
first refusal to act as the  Registrant's  underwriter  and placement agent with
respect to future  public and private  financing  and serve as the  Registrant's
investment   banker  with  respect  to  any   potential   acquisition,   merger,
divestiture, strategic planning or other activity, but only if the terms offered
by Commonwealth  are comparable to those then being offered by other  investment
banking firms to similarly situated companies. In

                                       -9-


<PAGE>
<PAGE>



addition,  pursuant to the  Placement  Agency  Agreement,  on February 15, 1996,
Commonwealth  and its  designees  purchased  for $.001 per warrant,  warrants to
purchase 723,500 shares of Common Stock,  each at an exercise price of $2.50 per
share,   subject  to  adjustment  in  certain  events  (the  "Placement  Agent's
Warrants").  The Placement Agent's Warrants will be  exercisable  for  a  period
of six years and are not redeemable by the Registrant under any circumstances.

         The  Registrant has agreed to register the Placement  Agent's  Warrants
and the underlying Common Stock on substantially  similar terms to the investors
in the Investment Transaction.  The number of shares of Common Stock deliverable
upon any exercise of the Placement  Agent's  Warrants and the exercise  price of
such warrants are subject to adjustment to protect against any dilution upon the
occurrence of certain events.

         Commonwealth  and the  Registrant  have also agreed to  indemnify  each
other  against  certain  civil  liabilities,  including  liabilities  under  the
Securities  Act, or to contribute to payments  either may be required to make in
respect thereof.

         The  foregoing  description  of the  Placement  Agency  Agreement  is a
summary of certain of the provisions contained in the Placement Agency Agreement
and reference is made to a copy of such  agreement  which is attached  hereto as
Exhibit  5 and is  incorporated  herein  by  reference  for all of its terms and
conditions.

LEAD INVESTOR

          In October 1995 and December  1995,  Charles S. Holmes,  a director of
the Registrant,  purchased two subordinated  notes of the Registrant each in the
principal

                                      -10-


<PAGE>
<PAGE>



amount of $1,000,000. In connection with such investment,  the Registrant agreed
that Mr.  Holmes may  designate  one of the two  individuals  to be appointed by
investors as directors of the  Registrant  to fill the  vacancies  which will be
caused by the  resignation  of two current  members of the Board of Directors of
the Registrant as discussed below.  Such notes were exchanged for 2,000 Units in
the  Investment  Transaction.  Mr. Holmes became a director of the Registrant in
October 1995.  Warrants to purchase an aggregate of 1,200,000 shares were issued
to Mr.  Holmes for past  advisory  services in  connection  with the  Investment
Transaction and the engagement of the Commonwealth.

         In December 1995 and January 1996, Active Investors II, Ltd.  purchased
subordinated  notes of the  Registrant  in the  aggregate  principal  amount  of
$900,000. C. Shelton James, a director of the Registrant, is the President and a
director of Active  Investors II, Ltd. In connection with such  investment,  the
Registrant agreed that Active Investors may designate one of the two individuals
to be  appointed  by  investors  as  directors  of the  Registrant  to fill  the
vacancies  which will be caused by the resignation of two current members of the
Board of  Directors  of the  Registrant  as  discussed  below.  Such  notes were
exchanged for 900 Units in the Investment Transaction. Active Investors II, Ltd.
indicated it would be interested  in  purchasing  an additional  100 Units on or
about  February  23, 1996.  Active  Investors  II, Ltd.  and certain  affiliated
limited  partnerships  currently  own  approximately  5.57% of the  Registrant's
Common Stock.

REVISED CREDIT AGREEMENT

                                      -11-


<PAGE>
<PAGE>



         Effective  January  5,  1996  the  Registrant  entered  into  a  fourth
amendment  to the Credit  Agreement  with its bank  lenders  which  amended  the
definition of the maturity date under the Credit  Agreement to mean February 15,
1996.

         Effective  February  15,  1996,  the  Registrant  entered  into a fifth
amendment to the Credit Agreement (the "Fifth  Amendment") with the Bank Lenders
which amended and extended the payment  provisions  contained  therein and reset
certain  financial  covenants on more favorable  terms for the  Registrant.  The
Fifth Amendment provides for principal payments of $500,000 on each of March 31,
1996,  June 30, 1996,  September  30, 1996 and December 31, 1996 and $750,000 on
the last day of each quarter thereafter, commencing on March 31, 1997 and ending
on December 31, 1998,  together  with  accrued and unpaid  interest  through the
applicable  payment  date.  The  remaining   outstanding   principal  amount  of
$7,975,000 is due and payable on January 15, 1999.  Borrowings  permitted  under
the  revised  Credit  Agreement  are  irrevocably  reduced  with each  quarterly
principal  payment.  The interest  rate,  bank fees,  collateral,  non-financial
covenants  and events of default  have not been  modified by the revised  Credit
Agreement.  Concurrent with the execution of the Fifth Amendment, the Registrant
amended  the  terms  of  certain  demand   registration   rights  and  piggyback
registration  rights granted to the Bank Lenders  pursuant to an Amendment No. 1
to  Registration   Rights  Agreement,   dated  as  of  February  13,  1996  (the
"Registration Rights Amendment").

         The foregoing description of the agreements executed in connection with
the Credit Agreement is a summary of certain of the provisions contained therein
and reference is made to a copy of such agreements  which are attached hereto as
Exhibit

                                      -12-

<PAGE>



6,  Exhibit  7 and  Exhibit  8,  respectively,  and are  incorporated  herein by
reference for all of their terms and conditions.

RESIGNATION OF DIRECTORS

         Effective upon completion of the Investment Transaction on February 15,
1996, two current members of the Board of Directors of the Registrant, Robert D.
Rosenthal and John M. May,  resigned from the Board.  The Registrant  intends to
appoint as directors one  individual  designated  by each of Messrs.  Holmes and
James who are  reasonably  acceptable to the Registrant to serve as directors so
long as the Notes are outstanding.  No persons have yet been designated to serve
in such capacity but are expected to be designated and appointed in March 1996.

         The  resignation  letters of  Messrs.  Rosenthal  and May are  attached
hereto as Exhibit 9 and Exhibit 10 respectively.

PRESS RELEASE

         On February 15, 1996, the Registrant issued a press release (the "Press
Release")  describing  the  closing  of  the  Investment   Transaction  and  the
Amendment.

         The Press Release is attached hereto as Exhibit 11.

                                   FORM OF

                  12% CONVERTIBLE SUBORDINATED PROMISSORY NOTE

                         MATURITY DATE: JANUARY 15, 2001

THIS NOTE AND THE COMMON  STOCK THAT MAY BE ISSUABLE  TO THE HOLDER  HEREOF HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, 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"), promises to pay to ______________________,  the registered holder or
registered   assigns   hereof   (the   "Holder"),   the   principal   amount  of
_________________  Dollars  ($_________) payable on the fifteenth day of January
2001 (the "Maturity Date"),  together with interest on the outstanding principal
amount of this Note at the rate of twelve percent (12%) per annum  calculated on
the basis of a 360 day  year,  such  interest  to be  payable  in  arrears  on a
quarterly basis on the fifteenth day of January, April, July and October of each
year,  commencing  on April 15,  1996.  In the  event  that any  payment  of any
principal and/or interest hereunder is not paid when due as provided for herein,
and without affecting any of the Holder's other rights and remedies,  the unpaid
principal  balance hereof shall thereafter accrue interest at the defaulted rate
specified in Section 11(a) of this Note.

         This  Note  is  one  of a  series  of  the  Company's  12%  Convertible
Subordinated  Promissory Notes (collectively,  the "Notes"),  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
13.

         1. Payments and Prepayments.

         (a)  Payments of  principal  and interest on this Note shall be made at
the  principal  office of the  Company,  located  at 2405 Trade  Centre  Avenue,
Longmont, Colorado 80503, or such other place or places within the United States
as may be  specified  by the  Holder  of this  Note in a  written  notice to the
Company at least ten (10) business days before a given payment date.

<PAGE>



         (b)  Payments of  principal  and interest on this Note shall be made in
lawful money of the United States of America by mailing the Company's good check
in the proper  amount to the Holder at least three days prior to the due date of
each payment or otherwise  transferring funds so as to be received by the Holder
on the due date of each such payment; provided, however, that, in the event that
the principal amount of this Note is at least $1,000,000, the Company shall make
payment by wire transfer to an account such Holder may specify in writing to the
Company at least three days prior to the due date of each payment.

         (c) If any payment on this Note  becomes due and payable on a Saturday,
Sunday  or  other  day on  which  commercial  banks  in New  York,  New York are
authorized or required by law to close,  the maturity  thereof shall be extended
to the next succeeding  business day and, with respect to payments of principal,
interest  thereon shall be payable during such extension at the then  applicable
rate.

         (d) Subject to the  provisions  of Section 4 and 5 below,  this Note is
subject to  prepayment,  in whole but not in part, at the option of the Company,
at any time after the third  anniversary of the date hereof,  without premium or
penalty.  In the event of any partial payment of principal or accrued  interest,
for whatever reason, or prepayment, any such partial payment of principal and/or
interest or  prepayment  of principal on the Notes shall be allocated  among the
respective Notes and holders thereof so that the amount of such payments to each
holder  shall  bear as nearly as  practicable  the same  ratio to the  aggregate
amount  then to be paid as the  principal  amount of the Notes then held by such
holder bears to the aggregate principal amount of Notes then outstanding.

         (e) The Company  will give the Holder  written  notice  indicating  the
amount of any  prepayment and the proposed date thereof not more than sixty (60)
days and not less than  thirty  (30) days prior to any such  prepayment  of this
Note.

         (f) Subject to the  provisions  of Sections 4 and 5 below,  the Company
shall, within thirty (30) business days of the occurrence of a Change in Control
(as defined in Section 13  hereof),  offer,  by written  notice to the Holder in
accordance  with Section  1(e),  to prepay this Note,  in whole and not in part,
without premium or penalty.  Holder may accept the offer to prepay made pursuant
to this Section 1(f) by causing notice of such acceptance to be delivered to the
Company at least ten (10) days prior to the  proposed  prepayment  date (or such
longer  period as may be required by law).  A failure by Holder to respond to an
offer to prepay  pursuant to this Section 1(f) within the requisite  time period
shall be deemed to constitute a rejection of such offer.

         2. Obligation  Absolute.  The obligations  under this Note are absolute
and  unconditional  obligations  of the  Company and no  modification,  release,
consent, waiver,  rearrangement or amendment shall impair the obligations of the
Company hereunder.

         3.  Security.  The payment of this Note and the  Company's  obligations
hereunder,  and under the Warrant and the Registration Rights Agreement (as such
terms are defined in the Memorandum) are not secured by any collateral.

         4.  Subordination.  (a) The  Company  for itself,  its  successors  and
assigns,  covenants and agrees, and each Holder of this Note, its successors and
assigns,  by its acceptance of this Note likewise covenants and agrees,  that to
the extent  provided  below the payment of the principal of and interest on this
Note is hereby  expressly  subordinated  and junior in right of payment,  to the
extent and in the manner  hereinafter set forth, to all Senior  Indebtedness (as
hereinafter defined). For purposes hereof, Senior Indebtedness is defined as:

                           (i)  the  principal  of,  premium,  if  any,  and any
                  interest  (including,  without  limitation,  any  interest  on
                  interest  and  post-bankruptcy   petition  interest)  on,  all
                  liabilities of the Company (including, without limitation, all
                  liabilities  of the  Company  with  respect  to any  costs and
                  expenses),   direct   or   contingent,   joint,   several   or
                  independent,  now or hereafter existing, due or to become due,
                  whether   created   directly  or  acquired  by  assignment  or
                  otherwise,  under or in respect of that  certain  Amended  and
                  Restated Credit  Agreement,  dated as of April 12, 1995, among
                  the Company, The Bank of New York, Chemical Bank and the other
                  parties  referred to therein (as  heretofore  and as hereafter
                  amended,  modified  and  supplemented  from time to time,  the
                  "Bank Credit  Agreement")  and any of the other Loan Documents
                  (as defined in the Bank Credit Agreement); and

                           (ii) all  extensions,  renewals and refundings of any
                  of the  foregoing  (provided  that  the  amount  of  any  debt
                  incurred  in  connection  with  such  extension,   renewal  or
                  refunding  does  not  exceed  the  amount  of the  outstanding
                  obligations of the Company under the Bank Credit  Agreement at
                  the time of the extension,  renewal or refunding  (whether for
                  interest,  principal  or fees,  or  expenses  incurred  by the
                  holders  of  Senior   Indebtedness   for  the   protection  of
                  collateral and reasonable costs of collection));

provided,  however,  that the term "Senior  Indebtedness"  shall not include any
indebtedness  expressly subordinated in writing to the Notes or any indebtedness
owed to affiliates of the Company.

         (b)  Upon  the  acceleration  of any  Senior  Indebtedness  or upon the
maturity of the entire principal  amount of any Senior  Indebtedness by lapse of
time, acceleration or otherwise,  all such Senior Indebtedness which has been so
accelerated  or matured  shall  first  indefeasibly  be paid in full  before any
payment is made by the Company or any person  acting on behalf of the Company on
account of any obligations evidenced by this Note.

         (c)  Notwithstanding  anything to the contrary  contained  herein,  the
Company  shall  not (i) pay any  principal  portion  of this Note so long as any
Senior  Indebtedness  remains outstanding or (ii) pay any interest payable under
this Note if there exists a Default or

                                        3


<PAGE>
<PAGE>



Event of Default (as such terms are defined in the instruments evidencing Senior
Indebtedness) with respect to any Senior Indebtedness  (hereinafter  referred to
as a "Blockage Event").

                  The Company  shall resume  payment of interest  payable  under
this Note and a Blockage Event shall be deemed to have terminated:

                    (i)  when  such  Default  or  Event  of  Default  on  Senior
               Indebtedness, as applicable, is cured or waived;

                    (ii)  when the  Holder  hereof  shall  have  cured  any such
               Default or Event of Default on Senior  Indebtedness to the extent
               such  Default  or Event of  Default  can be cured by  payment  of
               money,  which amount shall be added to the principal amount owing
               to the Holder pursuant to this Note; or

                    (iii) 180 days after the occurrence of such Default or Event
               of Default, provided, that at the end of such 180 days, if any of
               the following  events exists or occurs,  the Blockage Event shall
               continue:  (A) a Default in payment of any amount with respect to
               the  Senior  Indebtedness;  (B) an  acceleration  of  the  Senior
               Indebtedness;  or (C) the  occurrence  of an  event  of the  type
               described in Section 5 hereof, provided, further, that a Blockage
               Event  with  respect  to a single  specified  Default or Event of
               Default may be deemed to occur only once for each 360 day period.

         (d) At any time there exists a Blockage  Event,  (i) the Company  shall
not, directly or indirectly, make any payment of any part of this Note, (ii) the
Holder  hereof  shall not demand or accept from the Company or any other  person
any such  payment or  cancel,  set-off or  otherwise  discharge  any part of the
indebtedness  represented  by this Note,  and (iii)  neither the Company nor the
Holder  hereof  shall  otherwise  take or permit  any action  prejudicial  to or
inconsistent  with the  priority  position of any holder of Senior  Indebtedness
over the  Holder  of this  Note.  Notwithstanding  the  foregoing  or any  other
provision of this Note to the contrary,  the  occurrence  and  continuance  of a
Blockage Event shall not limit or in any other manner affect the exercise of the
Holder's conversion rights pursuant to Section 6.

         (e) Any holder of Senior  Indebtedness  is hereby  authorized to demand
specific  performance  of this  Note,  whether  or not the  Company  shall  have
complied  with the  provisions  hereof  applicable  to it,  at any time when the
Holder hereof shall have failed to comply with any provision  hereof  applicable
to such Holder.  The Holder hereby  irrevocably  waives any defense based on the
adequacy  of a remedy at law which  might be  asserted as a bar to the remedy of
specific  performance  hereof in any action  brought  therefor  by any holder of
Senior Indebtedness.  The Holder further (i) waives presentment,  demand, notice
and protest in connection  with all  negotiable  instruments  evidencing  Senior
Indebtedness,  notice of any loan made,  extension granted or other action taken
in reliance  hereon and all demands and notices of every kind in connection with
this Note or Senior Indebtedness;  and (ii) assents to any renewal, extension or
postponement of the time of payment of Senior Indebtedness or any other

                                        4

<PAGE>



indulgence with respect  thereto,  to any  substitution,  exchange or release of
collateral  therefor and to the  addition or release of any person  primarily or
secondarily liable thereon.

         (f) The Company and the Holder shall  execute and deliver to any holder
of Senior  Indebtedness  such  further  instruments  and shall take such further
action as such holder of Senior Indebtedness may at any time or times reasonably
request in order to evidence the subordination of the obligations  hereunder and
to otherwise carry out the provisions and intent of this Note.

         (g) No right of any  holder  of  Senior  Indebtedness  to  enforce  the
subordination of the obligations  shall be impaired by any act or failure to act
by the Company or the Holder or by their failure to comply with this Note or any
other agreement or document  evidencing,  related to or securing the obligations
hereunder. Without in any way limiting the generality of the preceding sentence,
the  holders  of  Senior  Indebtedness  may,  at any time and from time to time,
without the consent of or notice to the Holder, without incurring responsibility
to the Holder and without impairing or releasing the  subordination  provided in
this Note or the  obligations  of the  Holder  hereof to the  holders  of Senior
Indebtedness,  do any one or more of the following: (i) change the manner, place
or terms of payment of, or renew or alter, any Senior Indebtedness, or otherwise
amend or supplement in any manner, any Senior  Indebtedness,  or otherwise amend
or  supplement  in  any  manner,  any  Senior  Indebtedness  or  any  instrument
evidencing  the  same  or any  agreement  under  which  Senior  Indebtedness  is
outstanding;  (ii) sell,  exchange,  release or otherwise deal with any property
pledged, mortgaged or otherwise securing any Senior Indebtedness;  (iii) release
any  Person or entity  liable in any  manner  for the  collection  of any Senior
Indebtedness;  and (iv) exercise or refrain from  exercising  any rights against
the Company or any other Person or entity.

         (h) In the event that the Company  shall make any payment or prepayment
to the Holder on account of the obligations  under this Note which is prohibited
by this  Section 4, such payment  shall be held by the Holder,  in trust for the
benefit of, and shall be paid  forthwith  over and  delivered to, the holders of
Senior  Indebtedness  (pro rata as to each of such  holders  on the basis of the
respective  amounts and priorities of Senior  Indebtedness  held by them) to the
extent  necessary to pay all Senior  Indebtedness  due to such holders of Senior
Indebtedness  in full in accordance  with its terms  (whether or not such Senior
Indebtedness is due and owing), after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness.

         (i)  After all  Senior  Indebtedness  indefeasibly  is paid in full and
until the  obligations  under this Note are paid in full,  the  Holder  shall be
subrogated  to the rights of holders of Senior  Indebtedness  to the extent that
distributions  otherwise  payable to the Holder have been applied to the payment
of Senior  Indebtedness.  For  purposes  of such  subrogation,  no  payments  or
distributions  to holders of such Senior  Indebtedness of any cash,  property or
securities  to which the Holder would be entitled  except for the  provisions of
this Section 4 and no payment over pursuant to the  provisions of this Section 4
to holders of such  Senior  Indebtedness  by the Holder,  shall,  as between the
Company, its creditors, other than holders of

                                        5


<PAGE>
<PAGE>



such  Senior  Indebtedness,  and the  Holder,  be deemed to be a payment  by the
Company to or on account of such Senior  Indebtedness,  it being understood that
the  provisions  of this  Section 4 are solely for the purpose of  defining  the
relative rights of the holders of such Senior Indebtedness, on the one hand, and
the Holder hereof, on the other hand.

         5. Primacy of Senior  Indebtedness Claims as Against the Holder. In any
insolvency, receivership, bankruptcy, dissolution, liquidation or reorganization
proceeding, or in any other proceeding,  whether voluntary or involuntary, by or
against the Company under any  bankruptcy or insolvency  law or laws relating to
relief of debtors, to compositions, extensions or readjustments of indebtedness:

          (a) the  claims of any  holders  of Senior  Indebtedness  against  the
     Company  shall be paid  indefeasibly  in full in cash before any payment is
     made to the Holder;

          (b) until all Senior Indebtedness is indefeasibly paid in full in cash
     any distribution to which the Holder would be entitled but for this Section
     5 shall be made to holders of Senior Indebtedness; and

          (c) the  holders  of  Senior  Indebtedness  shall  have  the  right to
     enforce,  collect and receive every such payment or  distribution  and give
     acquittance  therefor.  In furtherance of the foregoing,  in the event that
     the  Company  shall  file or have filed  against  it a  petition  under any
     chapter of Title 11 of the United  States Code or any  comparable  statute,
     with the result that the Company is excused from the  obligation to pay all
     or any part of the  amount  otherwise  payable  in  respect  of the  Senior
     Indebtedness  during  the period  subsequent  to the  commencement  of such
     proceedings,  the Holder  agrees that all or such part of such amount shall
     be payable  out of, and to that extent  diminish  and be at the expense of,
     the Holder's reorganization  dividends or other distributions in respect of
     any claim filed by it as a creditor or  interest  holder.  In the event the
     holders of Senior Indebtedness receive amounts in excess of payment in full
     (in cash) of amounts outstanding in respect of Senior Indebtedness (without
     giving effect to whether claims in respect of the Senior  Indebtedness  are
     allowed  in  any  insolvency   proceeding),   the  holders  of  the  Senior
     Indebtedness shall pay such excess amounts to the Holder.

         6. Conversion. The Holder of this Note will have the right, exercisable
at any time on or before  the  Maturity  Date,  by notice to the  Company at its
principal  office,  at the Holder's option, to convert the then unpaid principal
amount of this Note (or any  portion  hereof  that is an  integral  multiple  of
$1,000) into 500 fully paid and non-assessable shares of common stock, par value
$.10 per share,  of the Company (the "Common Stock") for each $1,000 face amount
of this Note,  representing a conversion price equal to $2.00 per share, subject
to adjustment as set forth below (the  "Conversion  Price").  The Company may at
any time,  by notice  to the  Holder,  require  the  conversion  of this Note in
accordance  with this Section 6, and the Holder shall  promptly  surrender  this
Note for conversion  following such notice,  provided that the Closing Price for
the Common Stock for thirty (30)  consecutive  trading days prior to such notice
is equal to or greater than $6.00 per share.

                                        6

         Subject to the right of the Holder on the date of conversion to receive
all interest on such Note accrued through such date of conversion, no adjustment
for  interest or dividends  will be made upon the  conversion  of this Note.  No
fractional shares will be issued upon conversion,  but if the conversion results
in a fraction,  the fair market value of such  fractional  share 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) will be paid by the Company in cash. This
right of  conversion  shall  cease  upon  payment in full of all  principal  and
interest  and other  amounts due in respect of this Note.  Nothing  contained in
this  paragraph  shall  authorize the payment of interest to the Holder when the
terms of this Note otherwise prohibit the same.

         The  occurrence  of  any of  the  following  events  shall  trigger  an
adjustment from time to time to the Conversion Price and the number of shares of
Common Stock into which this Note shall be converted (the "Conversion Shares"):

          (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  Note  remains
     outstanding,    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 Note thereafter
     shall have the right to receive upon the  conversion  hereof as provided in
     this  Section  6 and in lieu of the  shares  of  Common  Stock  immediately
     theretofore  issuable  upon the  conversion  of this Note,  such  shares of
     capital  stock,  securities  or other  property as may be issued or payable
     with respect to or in exchange for a number of outstanding shares of Common
     Stock equal to the number of shares of Common Stock immediately theretofore
     issuable  upon the  conversion  of this  Note  had  such  recapitalization,
     reclassification,  merger, consolidation, sale or transfer not taken place,
     and in each such case,  the terms of this Note shall be  applicable  to the
     shares  of  stock or  other  securities  or  property  receivable  upon the
     conversion of this Note after such consummation.

          (b)  Subdivision or Combination of Shares.  If the Company at any time
     while this Note remains  outstanding  shall subdivide or combine its Common
     Stock,   the  Conversion   Price  and  the   Conversion   Shares  shall  be
     proportionately adjusted.

          (c) Stock  Dividends  and  Distributions.  If the  Company at any time
     while this Note is outstanding 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  Conversion  Price  shall be  adjusted in
     accordance with Section 6(e) and (ii) the number of Conversion Shares shall
     be adjusted to the number of shares of Common  Stock that the Holder  would
     have owned  immediately  following such action had this Note been converted
     immediately prior thereto.

                                        7

          (d) Stock and Rights  Offering to  Shareholders.  If at any time after
     the date of issuance of this Note,  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 lowest Closing Price during
     the twenty (20) consecutive trading days immediately  preceding the date of
     such issuance or sale or such record date then,  immediately after the date
     of such issuance or sale or on such record date, (A) the  Conversion  Price
     shall be adjusted in  accordance  with  Section  6(e) and (B) the number of
     Conversion   Shares  shall  be  adjusted  to  that  number   determined  by
     multiplying the number of Conversion Shares  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 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
     Note  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
     conversion  of this Note so that, in addition to the shares of 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, converted this Note.

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

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

                                        8


<PAGE>
<PAGE>




               (i) if the  Company  shall  achieve  1996 EBITDA (as such term is
          defined in Section  13(h)) in an amount of less than  $6,000,000,  the
          Conversion Price shall be reduced to $1.50 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 Conversion Price shall be reduced
          to $1.00 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 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 6 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 6 if
     the amount of such  adjustment  should be less than one percent (1%) of the
     Conversion  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 Conversion  Price in effect
     immediately   before  the  event  giving  rise  to  such  next   subsequent
     adjustment.

          (i) Duration of Adjustment. Following each computation or readjustment
     provided in this Section 6, the new adjusted Conversion Price and number of
     Conversion  Shares shall remain in effect  until a further  computation  or
     readjustment thereof is required.

          (j)  Reservation.  The Company  hereby  agrees that at all times there
     shall be reserved for issuance upon the conversion of this Note such number
     of  shares of its  Common  Stock as shall be  required  for  issuance  upon
     conversion of this Note.  The Company  further agrees that all shares which
     may be issued upon the  conversion of the rights  represented  by this Note
     will be duly  authorized and will, upon issuance and against payment of the
     Conversion 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

                                        9


<PAGE>
<PAGE>



     respect of any transfer occurring  contemporaneously with such issuance and
     other than transfer  restrictions  imposed by federal and state  securities
     laws.

          (i) Delivery of Shares  and/or New Note.  The Company  shall deliver a
     certificate  or  certificates  for shares of its Common  Stock  issuable on
     conversion of this Note as soon as practicable after surrender of this Note
     for  conversion,  but the person or persons to whom such  certificates  are
     issuable  shall be considered  the holder of record of the shares of Common
     Stock from the time this Note is  surrendered.  Except as described  above,
     this Note is not otherwise  convertible  into shares of Common Stock.  Upon
     conversion  of only a portion of this Note,  the  Company  shall  issue and
     deliver to, or upon the written order of, the Holder hereof, at the expense
     of the Company,  a new Note covering the principal  amount of this Note not
     converted,  which new Note shall entitle the holder  thereof to interest on
     the  principal  amount  thereof  to the same  extent as if the  unconverted
     portion of this Note had not been surrendered for conversion.

         7. Notices 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 conversion of
     this Note) 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 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 conversion of this Note) 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, liquidation or winding-up. Such
notice shall be mailed at least

                                       10


<PAGE>
<PAGE>



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
other specified date.

         (b)  Certificate  of Adjustment.  Whenever the Conversion  Price or the
number of Conversion Shares shall be adjusted pursuant to Section 6 hereof,  the
Company  shall  promptly  make a  certificate  signed by 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 number of Conversion  Shares and the  Conversion  Price
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 Note.

         8.  Registration,  Exchange  and  Transfer.  The  Company  will  keep a
register in which,  subject to such reasonable  regulations as it may prescribe,
it will  register all Notes.  No transfer of this Note shall be valid as against
the  Company  unless  made  upon  the  register.  This  Note is  subject  to the
restrictions on transfer of this Note and compliance  with said  restrictions on
transfer, the Company shall execute and deliver in the name of the transferee or
transferees a new Note or Notes for a like principal amount.

         This Note may be exchanged  for a like  aggregate  principal  amount in
other  denominations.  To be exchanged,  this Note shall be surrendered for that
purpose at the  principal  office of the Company,  and the Company shall execute
and deliver in exchange  therefor the Note or Notes which the holder  making the
exchange   shall  be   entitled   to  receive,   bearing   serial   numbers  not
contemporaneously outstanding.

         This Note, if presented for transfer, exchange,  redemption or payment,
shall (if so required by the Company) be duly endorsed by, or be  accompanied by
instruments  of transfer in form  satisfactory  to the Company duly executed by,
the registered Holder or by his duly authorized attorney.

         The  Company  may deem and treat the  registered  Holder  hereof as the
absolute  owner  hereof   (whether  or  not  this  Note  shall  be  overdue  and
notwithstanding  any  notation of ownership  or other  writing  hereon by anyone
other than the Company),  for the purpose of receiving  payment of or on account
of the principal hereof and interest hereon,  for the conversion  hereof and for
all other  purposes,  and the Company shall not be affected by any notice to the
contrary.

         9.  Covenants.  The  Company  covenants,  so long as this Note shall be
outstanding  and unless the Holders of more than  seventy-five  percent (75%) of
the aggregate  principal  amount of all Notes then  outstanding  shall otherwise
approve, that:

          (a)  Financial  Statements,  Reports,  etc. So long as this Note shall
     remain outstanding and the Company is subject to the filing requirements of
     Section 13(a),  13(c) or 15(d) of the  Securities  Exchange Act of 1934, as
     amended (the "Exchange Act"), the Company

                                       11


<PAGE>
<PAGE>



     will transmit or cause to be transmitted to the Holder,  promptly after the
     same are sent or become publicly available, copies of any and all financial
     statements and reports which are made available to its shareholders and all
     periodic and other reports, proxy statements,  registration  statements and
     other materials filed by it with the Securities and Exchange Commission, or
     any other governmental  authority succeeding to any or all of the functions
     of said commission, or any national securities exchange or stock market, as
     the case may be. If the Company is not subject to filing requirements,  the
     Company will transmit or cause to be  transmitted  to the Holder annual and
     quarterly  reports  containing  audited  annual  financial  statements  and
     related  notes  thereto  and  unaudited  quarterly  financial   statements,
     respectively.

          (b)  Registration  of Shares.  The Company  shall file a  registration
     statement with the Securities and Exchange  Commission under the Securities
     Act of 1933, as amended (the "Act"),  with respect to the Notes, the shares
     of Common  Stock  issuable  pursuant  hereto,  the  Warrant  referred to in
     Section 16(a) and the shares of Common Stock  issuable upon the exercise of
     the  Warrant  on or prior to the later of (i)  ninety  (90) days  after the
     Company's  receipt of the net proceeds from the initial sale of the minimum
     principal  amount  of the  Notes or (ii)  March  31,  1996,  pursuant  to a
     registration  rights agreement of even date herewith between the Holder and
     the Company.

          (c)  Corporate  Existence.  The  Company  shall,  and shall  cause its
     Subsidiaries  to, do or cause to be done all things  necessary to preserve,
     renew and keep in full force and effect its corporate  existence,  material
     rights,  licenses,  permits  and  franchises  and  comply  in all  material
     respects with all laws and regulations applicable to it.

          (d) Taxes and  Assessments.  The  Company  shall,  and shall cause its
     Subsidiaries to, pay and discharge all taxes,  assessments and governmental
     charges  or levies  imposed  upon it or upon its  income or  profits  or in
     respect of its  property,  before the same shall become in default  (which,
     for purposes of this Note,  shall mean the earlier of ninety (90) days from
     its due date or  invoice  date,  as the case may be, or the date upon which
     such obligee  commences an action or  proceeding  to recover such  amount),
     provided,  however,  that the  Company  shall  not be  required  to pay and
     discharge or to cause to be paid and discharged  any such tax,  assessment,
     charge,  levy or claim so long as the validity or amount  thereof  shall be
     contested in good faith by  appropriate  proceedings  (if the Company shall
     have set aside on its books adequate reserves therefor).

          (e) Liens.  The  Company  shall  not,  and shall not permit any of its
     Subsidiaries to, incur,  create,  assume or suffer to exist any Lien on any
     property  or  assets,  income  or  profits  of the  Company,  now  owned or
     hereafter acquired, other than Permitted Liens.

          (f)  Indebtedness.  The Company shall not, and shall not permit any of
     its Subsidiaries to, contract, create, incur, assume or suffer to exist any
     Indebtedness,  except for (i) Senior Indebtedness;  (ii) Indebtedness under
     this Note and the  other  Notes in an  aggregate  principal  amount  not to
     exceed $9,500,000; (iii) Indebtedness between Subsidiaries and between

                                       12

     any  Subsidiary  and the Company;  (iv)  Indebtedness  existing on the date
     hereof;  (v) Indebtedness of Lynwood  Scientific  Developments  Limited,  a

     equivalent in English pounds; (vi) Indebtedness of Codar Technology,  Inc.,
     a Colorado  corporation,  to MetLife  Capital Corp.  and Colorado  National
     Leasing,  Inc. in an aggregate amount not to exceed  $1,200,000;  and (vii)
     all extensions, renewals and refundings of any of the foregoing.

          (g)  Investments.  The Company  shall not, and shall not permit any of
     its Subsidiaries to, purchase,  hold or acquire any capital stock, evidence
     of indebtedness  or other  securities of, make or permit to exist any loans
     or  advances  to,  or make or permit  to exist  any  investment  (by way of
     transfers of property, contributions to capital, acquisitions of businesses
     or acquisitions of assets other than in the ordinary course of business, or
     otherwise) or any other interest in, any other Person, except for Permitted
     Investments.

          (h)  Payments.  The Company shall not, and shall not permit any of its
     Subsidiaries to, declare or pay,  directly or indirectly,  any dividends or
     make  any  other  distribution  or  payment,  whether  in  cash,  property,
     securities or a combination thereof,  with respect to (whether by reduction
     of capital or  otherwise)  any  shares of  capital  stock (or any  options,
     warrants,  rights or other equity securities or agreements  relating to any
     capital stock) now or hereafter outstanding, or purchase, redeem, retire or
     otherwise  acquire for value any shares of its capital stock or warrants or
     options therefor now or hereafter outstanding, or set apart any sum for the
     aforesaid  purposes,  in any fiscal  year,  provided  that the  Company may
     declare  stock  splits and pay  dividends  payable  solely in shares of any
     class of its capital stock and the Subsidiaries may make cash distributions
     or payments to the Company.

          (i) Disposition of Assets. The Company shall not, and shall not permit
     any of its  Subsidiaries  to,  sell or  otherwise  dispose  of any  assets,
     including  the  capital  stock of any of its  Subsidiaries,  except for (i)
     sales of  inventory,  fixtures  and  equipment  in the  ordinary  course of
     business,  (ii) sales of assets having a book value not exceeding  $100,000
     in the aggregate,  and (iii) the sale of certain  vacant  property owned by
     the Company located in Hauppauge, New York.

          (j) Affiliate Transactions. Subsequent to the date hereof, the Company
     shall not, and shall not permit any Subsidiary to,  directly or indirectly,
     enter  into or  permit  to exist  any  transaction  or  series  of  related
     transactions (including, but not limited to, the purchase, sale or exchange
     of property,  the making of any investment,  the giving of any guarantee or
     the rendering of any service) with any Affiliate of the Company (other than
     transactions among the Company and any wholly-owned  Subsidiary) unless (i)
     such  transaction  or series of  related  transactions  is on terms no less
     favorable  to the  Company  or such  Subsidiary  than  those  that could be
     obtained in a comparable arm's length transaction with a Person that is not
     an Affiliate,  and (ii) such transaction or series of related  transactions
     is  approved  by a  majority  of the  Board  of  Directors  of the  Company
     (including a majority of the  disinterested  directors),  which approval is
     set  forth  in a board  resolution  of the  Company  certifying  that  such
     transaction  or  series  of  transactions  complies  with  the  immediately
     preceding clause (i).

                                       13

<PAGE>




          (k) Merger, Consolidation, etc. Neither the Company nor any Subsidiary
     shall consolidate or merge with, or convey, transfer or lease substantially
     all of its assets in a single transaction or series of transactions to, any
     other Person unless (i) the successor  formed by such  consolidation or the
     survivor of such merger or the Person that acquires by conveyance, transfer
     or lease substantially all of the assets of the Company as an entirety,  as
     the case may be (the  "Successor"),  shall have  executed and  delivered to
     Holder  its  assumption  of the due  and  punctual  performance  of all the
     obligations  under this Note,  (ii) such  Successor  shall be a corporation
     organized and existing under the laws of the United States of America,  any
     state thereof or the District of Columbia,  and (iii) no event  referred to
     in Section 8 shall have occurred and be continuing.

          (l) Maintenance of Properties. The Company shall, and shall cause each
     of its Subsidiaries  to, keep all properties  useful in the business of the
     Company in good  working  order and  condition  except to the  extent  that
     discontinuing  the operation or maintenance  of any such  properties is, in
     the judgment of the Company, desirable in the conduct of its business.

         10. Events of Default. (a) In the event that:

          (i) the Company defaults in the payment of any installment of interest
     required  to be made on this Note and such  default  shall  continue  for a
     period of ten (10) days;

          (ii) the Company  defaults in making any payment of  principal on this
     Note required to be made on this Note;

          (iii) any  obligation of the Company or any Subsidiary for the payment
     of borrowed  money in excess of  $500,000  becomes or is declared to be due
     and payable  prior to its  expressed  maturity,  unless the validity of any
     such  indebtedness  or  obligation  is  being  contested  in good  faith by
     appropriate proceedings;

          (iv) any warrant of attachment, execution or other writ is levied upon
     any  property  or  assets of the  Company  or any  Subsidiary  in excess of
     $500,000 and is not discharged or stayed  (including  stays  resulting from
     the filing of an appeal) within thirty (30) days;

          (v) all or any  substantial  part of the assets or  properties  of the
     Company or any  Subsidiary  are condemned,  seized or  appropriated  by any
     government  or  governmental  authority;  or any  order is  entered  in any
     proceeding  directing  the  winding-up,  dissolution  or  split-up  of  the
     Company;

          (vi) the Company or any Subsidiary  hereafter  makes an assignment for
     the benefit of  creditors,  or files a petition in bankruptcy as to itself,
     is  adjudicated  insolvent  or bankrupt,  petitions  any receiver of or any
     trustee for the Company

                                       14

     or  any  substantial  part  of  the  property  of  the  Company  under  any
     bankruptcy, reorganization,  arrangement, readjustment of debt, dissolution
     or liquidation law or statute of any jurisdiction, whether or not hereafter
     in effect; or if there is hereafter  commenced against the Company any such
     proceeding  and  an  order  approving  the  petition  is  entered  or  such
     proceeding  remains  undismissed  for a period of sixty (60)  days,  or the
     Company by any act or omission to act  indicates its consent to or approval
     of or  acquiescence  in  any  such  proceeding  or the  appointment  of any
     receiver  of, or trustee for,  the Company or any  substantial  part of its
     properties,  or suffers any such  receivership  or  trusteeship to continue
     undischarged for a period of sixty (60) days; or

          (vii) the Company  defaults in the due observance or  performance,  in
     any  material  respect,  of any  covenant,  condition  or  agreement  to be
     observed  or  performed  pursuant  to the terms of this Note  (other than a
     default  which is  specifically  provided  for in this Section 10) and such
     default  continues  unremedied  for more than thirty (30) days after notice
     thereof to the Company;

then, and in each and every such case,  the holders of not less than  one-fourth
(1/4) in  aggregate  principal  amount  of  outstanding  Notes may  declare  the
principal and accrued but unpaid interest of all the Notes to be due and payable
immediately, by written notice to the Company, and upon any such declaration the
same  shall  become and shall be  immediately  due and  payable,  subject to the
subordination provisions of Section 4 hereof. At any time after such declaration
of  acceleration  has been made,  and before a judgment or decree for payment of
money due has been  obtained,  the holders of a majority in aggregate  principal
amount of the outstanding  Notes may, by written notice to the Company,  rescind
and annul such declaration.

         (b) At any time  before the date of any  declaration  accelerating  the
maturity of this Note:  (i) the  holders of at least  sixty-six  and  two-thirds
percent (66.67%) in aggregate  principal  amount of outstanding  Notes may waive
any past Event of Default  and its  consequences  pertaining  to the  payment of
interest on, or the  principal  of, any of the Notes;  and (ii) the holders of a
majority  in  aggregate  principal  amount of Notes may waive any other Event of
Default  hereunder.  Such waivers shall be evidenced by written  notice or other
document  specifying  the Event or Events of Default  being  waived and shall be
binding on all existing or subsequent holders of outstanding Notes.

         11. Certain Consequences Upon Default.

         (a) Defaulted  Interest.  Subject to the  provisions of Section 4 and 5
hereof,  if the  Company  shall  default in the payment of the  principal  of or
interest on this Note,  whether upon maturity,  by  acceleration,  or otherwise,
including,  without  limitation,  as a  result  of a  Chapter  11 or  Chapter  7
bankruptcy  case  commenced by or against the Company in which it is the debtor,
the  Company  shall on demand  from  time to time pay  interest,  to the  extent
permitted by law, on such defaulted amount up to (but not including) the date of
actual  payment  (whether  before  or after  judgment)  at the  rate  per  annum
(computed on the basis of the actual

                                       15


<PAGE>
<PAGE>



number  of days  elapsed  over a year of 360  days) at the rate set forth in the
introduction of this Note, plus six percentage  points (6%). It is the intention
of the Company and the holder of this Note to comply with applicable  usury laws
(now or hereafter  enacted);  accordingly,  notwithstanding any provision to the
contrary in this Note, and any other document  executed in connection  herewith,
in no event  shall this Note or any such other  document  require the payment or
permit the collection of interest in excess of the maximum  amount  permitted by
such laws. If for any circumstances whatsoever,  fulfillment of any provision of
this  Note  or of any  such  other  document  at the  time  performance  of such
provision  shall be due,  shall  involve  transcending  the  limit  of  validity
prescribed by law for the collection or charging of interest,  then, ipso facto,
the  obligation to be fulfilled  shall be reduced to the limit of such validity,
and if for any such  circumstances  the holder of this Note  shall ever  receive
anything of value as interest or deemed  interest by  applicable  law under this
Note or any such other  document or  otherwise  an amount that would  exceed the
highest  lawful  rate,  such amount that would be  excessive  interest  shall be
applied to the  reduction  of the  principal  amount owing under this Note or on
account of any other  indebtedness of the Company to such holder, and not to the
payment of interest, or if such excessive interest exceeds the unpaid balance of
principal of such indebtedness, such excess shall be refunded to the Company. In
determining  whether or not the  interest  paid or payable  with  respect to any
indebtedness  of the  Company to the  Holder,  under any  specific  contingency,
exceeds the highest  lawful  rate,  the  Company and such holder  shall,  to the
maximum extent permitted by applicable law, (i)  characterize any  non-principal
payment as an expense,  fee or premium  rather than as  interest,  (ii)  exclude
voluntary prepayments and the effects thereof, (iii) amortize, prorate, allocate
and  spread  the  total  amount  of  interest  throughout  the full term of such
indebtedness  so that the  actual  rate of such  interest  does not  exceed  the
maximum  amount  permitted by  applicable  law,  and/or (iv)  allocate  interest
between  portions of such  indebtedness,  to the end that no such portion  shall
bear interest at a rate greater than that permitted by applicable law.

         (b) Additional  Director  Nominee.  If and whenever interest payable on
this Note shall be in arrears in whole or in part,  or if the Company shall fail
to pay the  principal of this Note  (whether or not  prevented  from doing so by
restrictions contained in its Restated Certificate of Incorporation,  as amended
from time to time, or any other agreement or instrument),  the existing  members
of the Board of Directors  shall cause one Director then serving on the Board of
Directors  (who has not been  designated  by the  holders  of Notes,  Charles S.
Holmes or C.  Shelton  James) to resign as a  director,  and the  holders of the
Notes  shall be  entitled  to  immediately  appoint  one  Director  to fill such
vacancy, provided, that if such Director appointed by the holders, together with
the other  directors  designated by the holders of Notes and Messrs.  Holmes and
James, would not exceed 50% of the total Board of Directors,  then in such event
the holders of Notes shall be entitled to appoint additional Directors (upon the
resignation of other  non-designated  existing  Directors) so as its and Messrs.
Holmes'  and  James'  designees  constitute  a  majority  of the total  Board of
Directors.  Whenever all arrears in interest on the Notes then outstanding shall
have been paid and all principal amounts required to be made with respect to any
Notes shall have been made or funds  therefor  set apart for  payment,  then the
right  of the  holders  of  Notes  to  designate  one  Director  (or two or more
Directors,  as the case may be)  shall  cease  (but  subject  always to the same
provisions for the vesting of such rights in

                                       16


<PAGE>
<PAGE>



the case of any  similar  future  arrearages  in interest or failures to satisfy
principal  obligations),  and the  terms of  office of all  persons  elected  as
Directors by the holders of Notes shall  forthwith  terminate  and the number of
members on the Board of Directors appointed by the holders of the Notes shall be
reduced  accordingly.  At any time after such power shall have been so vested in
the Notes, the Secretary of the Corporation may, and upon the written request of
any holder of Notes  (addressed to the Secretary at the principal  office of the
Company) shall,  call a special meeting of the holders of Notes for the election
of the Director (or two or more Directors,  as the case may be) to be designated
by them as  herein  provided,  such call to be made by  notice  similar  to that
provided in the By-laws for a special meeting of the shareholders or as required
by law. If any such  special  meeting  required  to be called as above  provided
shall not be called by the Secretary  within  fifteen (15) days after receipt of
any such  request,  then any  holder of Notes may call  such  meeting,  upon the
notice above provided, and for that purpose shall have access to the register of
holders of the Notes of the  Company.  The  Director(s)  designated  at any such
special  meeting  shall  hold  office  until  the  next  annual  meeting  of the
shareholders  or  special  meeting  held  in  place  thereof  and be  re-elected
successively thereafter,  if such office shall not have previously terminated as
above provided.  In case any vacancy shall occur among the Directors  designated
by the holders of Notes, a successor  shall be elected by the Board of Directors
to serve until the next annual meeting of the  shareholders  or special  meeting
held in place  thereof  upon the  nomination  of the  then  remaining  Directors
designated by the holders of Notes and Messrs. Holmes and James.

         (c) Additional Warrants.  In the event there occurs an Event of Default
pertaining to the payment of interest on, or the principal of, any of the Notes,
the  Company  shall  issue to the  holders of the Notes  additional  warrants to
purchase  2,000,000 shares of Common Stock,  each holder to receive his pro rata
share.

         12. Investment Representations.

         (a) The Holder hereby  acknowledges  that this Note and the  Conversion
Shares  are not  being  registered  (i)  under  the Act on the  ground  that the
issuance of the Note 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 Note 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 Note for  investment  for its own  account,  with no present  intention  of
dividing its  participation  with others or reselling or otherwise  distributing
the same,  provided,  nevertheless,  subject to any  requirement of law that the
disposition of its property shall at all times be within its control.

         (b) The Holder  hereby  agrees that it will not sell or transfer all or
any part of this Note and/or  Conversion Shares unless and until, and so long as
such securities are not covered by an effective registration statement under the
Act, 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

                                       17

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 interpretive  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.

         (c)  If,  at  the  time  of  issuance  of  the  Conversion  Shares,  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 Holder
provide the Company  with  written  reconfirmation  of the  Holder's  investment
intent and that any stock certificate delivered to the Holder upon conversion of
this Note shall bear legends reading substantially as follows:

                  "TRANSFER OF THE SHARES  REPRESENTED  BY THIS  CERTIFICATE  IS
                  SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN THE NOTE PURSUANT
                  TO WHICH THESE  SHARES WERE ISSUED BY 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."

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.

         (d) The Company may refuse to  recognize a transfer of this Note or any
Conversion  Shares on its books should a holder attempt to transfer this Note or
any Conversion Shares otherwise than in compliance with this Section 12.

                        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


<PAGE>
<PAGE>



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

<PAGE>



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."

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


<PAGE>
<PAGE>



     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


<PAGE>
<PAGE>



     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


<PAGE>
<PAGE>



     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


<PAGE>
<PAGE>



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.

                            CERTIFICATE OF AMENDMENT

                                     of the

                          CERTIFICATE OF INCORPORATION

                             NAI Technologies, Inc.
                            (a New York corporation)

                       (Under Section 805 of the Business
                    Corporation Law of the State of New York)

         The undersigned, desiring to amend a certificate of incorporation under
the  provisions  of  the  Business  Corporation  Law of the  State  of New  York
(hereinafter referred to as the "BCL"), hereby certifies as follows:

         FIRST.  The  name  of  the  corporation  is  NAI   Technologies,   Inc.
(hereinafter  referred  to as the  "Corporation").  The  name  under  which  the
Corporation was originally formed is North Atlantic Industries, Inc.

         SECOND.  The original  Certificate of  Incorporation of the Corporation
was filed by the New York  Department  of State on July 15,  1954.  The Restated
Certificate  of  Incorporation  of the  Corporation  was filed with the New York
Department of State on August 19, 1991.

         THIRD.  Paragraph  "3"  of  the  Certificate  of  Incorporation  of the
Corporation, which sets forth the aggregate number and designations of shares of
stock  which the  Corporation  shall  have the  authority  to  issue,  is hereby
eliminated in its entirety and the  following  language is  substituted  in lieu
thereof  which has the effect of  increasing  from ten million  (10,000,000)  to
twenty-five  million  (25,000,000)  the  number of  shares  of Common  Stock the
Corporation shall have authority to issue:

         "3. The aggregate number of shares of stock which the Corporation shall
         have  the  authority  to  issue is  twenty-seven  million  (27,000,000)
         shares,  of which  twenty-five  million  (25,000,000)  shares  shall be
         designated  Common  Stock,  each such share having a par value of $.10,
         and of which two million (2,000,000)

<PAGE>
<PAGE>


         shares shall be designated Preferred Stock, each such
         share having a par value of $.10."

         FOURTH.  Paragraph  "4"  of the  Certificate  of  Incorporation  of the
Corporation,  which  sets  forth  the  terms  and  conditions  under  which  the
Corporation  may issue its Preferred  Stock,  is hereby restated in its entirety
without making any amendment to or change in the provisions thereof:

         "4. The Preferred Stock may be issued in series. The Board of Directors
         of the  Corporation  is hereby  expressly  authorized  to establish and
         designate series of Preferred Stock and to fix from time to time before
         issuance the number,  designation,  relative  rights,  preferences  and
         limitations  (including,  without  limitation,  participating,  voting,
         optional  or other  special  rights)  of the  shares  of any  series of
         Preferred Stock.  Except to the extent,  if any, that holders of issued
         and  outstanding  shares of Preferred  Stock are entitled to vote,  the
         entire  voting power for the  election of  directors  and for all other
         purposes  shall be vested  exclusively  in the holders of Common Stock,
         who shall be entitled  to one vote for each share of Common  Stock held
         by them of record."

         FIFTH:  The aforesaid  amendment to Paragraph 3 of the  Certificate  of
Incorporation  of the Corporation have been authorized (1) by the unanimous vote
of the Board of Directors of the Corporation taken at a meeting of said Board of
Directors  and (2) by the vote of the holders of a majority  of all  outstanding
shares of the  Corporation  entitled to vote thereon  taken at a meeting of said
shareholders, respectively, all in accordance with Section 803(a) of the BCL.

         IN WITNESS  WHEREOF,  the  Corporation  has caused this  Certificate of
Amendment of  Certificate  of  Incorporation  to be signed and subscribed in its
name this 1st day of February,  1996,  and the statements  contained  herein are
affirmed as true under the penalties of perjury.

         2. Required Registration Under the Securities Act.

         (a) The Company  shall,  for the benefit of the holders of  Registrable
Securities,  at the Company's  cost, file with the Commission on or prior to the
later of (i) ninety (90) days after the initial closing of the private placement
in which the Units are sold in accordance with the Memorandum (the "Closing") or
(ii) March 31, 1996, a Shelf  Registration  Statement  providing for the sale by
the holders of all the Registrable Securities, and shall use its best efforts to
have such Shelf  Registration  Statement declared effective by the Commission as
soon as practicable and, in any event,  within 60 days  thereafter.  The Company
agrees  to use  its  best  efforts  to keep  the  Shelf  Registration  Statement
continuously   effective  for  a  period  of  three  years  after  the  date  of
effectiveness  (the  "Effectiveness  Period").  The Company shall not permit any
securities  other  than  Registrable  Securities  to be  included  in the  Shelf
Registration,  except for up to 250,000  shares of Common Stock held by the Bank
Lenders (as such term is defined in the  Memorandum) and up to 363,636 shares of
Common Stock held by Active  Investors II, Ltd. The Company further  agrees,  if
necessary or appropriate, to supplement or

                                        3


<PAGE>
<PAGE>



amend the Shelf Registration Statement, if required by the rules, regulations or
instructions  applicable to the  registration  form used by the Company for such
Shelf Registration  Statement or by the Securities Act or by any other rules and
regulations  thereunder  for  shelf  registrations,  and the  Company  agrees to
furnish to the holders of Registrable  Securities  copies of any such supplement
or amendment promptly after its being used or filed with the Commission.

         (b) Effective  Registration  Statement.  A Shelf Registration Statement
pursuant  to  Section  2(a) above  will not be deemed to have  become  effective
unless it has been declared effective by the Commission; provided that if, after
it has been declared effective,  the offering of Registrable Securities pursuant
to a  Shelf  Registration  Statement  is  interfered  with  by any  stop  order,
injunction  or  other  order  or  requirement  of the  Commission  or any  other
governmental agency or court, such Registration  Statement will be deemed not to
have been effective during the period of such  interference,  until the offering
of Registrable  Securities  pursuant to such Registration  Statement may legally
resume.  The Company will be deemed not to have used its  reasonable  efforts to
cause the Shelf Registration Statement to become, or to remain, effective during
the requisite period if it voluntarily takes any action that would result in any
such Registration Statement not being effective or in the holders of Registrable
Securities  covered  thereby  not being able to offer and sell such  Registrable
Securities during that period.

         (c)  Additional  Interest.  In  the  event  that  either  (i)  a  Shelf
Registration Statement is not filed with the Commission on or prior to the later
of the 90th day after the Closing or March 31, 1996 (the "Filing Date"), or (ii)
a Shelf Registration Statement is not declared effective on or prior to the 60th
day after  the  Filing  Date,  the  interest  rate  borne by the Notes  shall be
increased  (the  "Additional  Interest")  by one  percent  per  annum  from  and
including  the 91st day after the  Closing  in the case of clause  (i) above and
from and including the 61st day after the Filing Date in the case of clause (ii)
above and shall  increase by an additional one percent per annum for each 90-day
period (or portion  thereof) that any  Additional  Interest  continues to accrue
pursuant to this Section  2(c);  provided  that the  aggregate  increase in such
interest  rate  pursuant to this  Section  2(c) will in no event  (other than as
stated in the  succeeding  proviso)  exceed  five  percent  (5%) per annum,  and
provided,  further,  that the interest rate shall  increase to eighteen  percent
(18%) in the event the Shelf Registration Statement is not effective nine months
after the Closing. Upon (x) the filing of a Shelf Registration  Statement in the
case of  clause  (i)  above  or (y) the  effectiveness  of a Shelf  Registration
Statement  in the case of  clause  (ii)  above,  and  provided  that none of the
conditions  set forth in  clauses  (i) or (ii)  above  continues  to exist,  the
interest rate borne by the Notes from the date of such filing or  effectiveness,
as the case may be, will be reduced to the original interest rate.

         In the event that the Shelf  Registration  Statement  has been declared
effective  and  subsequently  ceases  to be  effective  prior  to the end of the
Effectiveness  Period,  for a  period  in  excess  of 10  days,  whether  or not
consecutive, in any given year, then, the interest rate borne by the Notes shall
be  increased  by an  additional  one  percent  per annum on the 11th day in the
applicable  year such Shelf  Registration  Statement  ceases to be effective and
thereafter  by an additional  one percent per annum for each  additional 90 days
that such Shelf  Registration  Statement is not  effective,  subject to the same
provisions with respect to the increase in the

                                        4


<PAGE>
<PAGE>



interest  rate  referred to above;  provided that the interest rate borne by the
Notes will not be increased if the Registrable  Securities are otherwise  freely
tradeable  pursuant to Rule 144 under the Securities Act. Upon the effectiveness
of a Shelf Registration Statement, the interest rate borne by the Notes shall be
reduced to their original  interest rate unless and until increased as described
in this paragraph.

         The Company shall notify Commonwealth  Associates within three business
days  after  each and every  date on which an event  occurs in  respect of which
Additional  Interest is required to be paid (an "Event  Date").  The  Additional
Interest due shall be payable on each interest payment date to the record holder
of Notes entitled to receive the interest payment to be paid on such date as set
forth in the Notes.  Each obligation to pay Additional  Interest shall be deemed
to accrue from and including the day following the applicable Event Date.

         (d) Specific  Enforcement.  Without limiting the remedies  available to
the holders of Registrable Securities, the Company acknowledges that any failure
by the  Company to comply with its  obligations  under  Section  2(a) hereof may
result in  material  irreparable  injury to such  holders  for which there is no
adequate  remedy at law,  that it would not be possible  to measure  damages for
such injuries  precisely  and that,  in the event of any such failure,  any such
holder of  Registrable  Securities  may obtain such relief as may be required to
specifically enforce the Company's obligations under Section 2(a) hereof.

         3. Piggyback Registration Rights.

         (a) Right to Piggyback.  Whenever the Company  proposes to register any
Shares (or  securities  convertible  into or  exchangeable  or  exercisable  for
Shares) under the Securities Act, at any time on or before the Expiration  Date,
for its own  account  or for the  account  of other  Persons  exercising  demand
registration  rights  other than (i) pursuant to Section 4 below or (ii) under a
Registration  Statement  on Form S-4,  Form S-8 or any  successor  form filed in
connection  with an exchange  offer or an offering of  securities  solely to the
Company's existing  employees or security holders (a "Piggyback  Registration"),
the  Company  will give  prompt  written  notice to all  holders of  Registrable
Securities of its intention to effect such a Registration  and will use its best
efforts,   subject  to  Section  3(b)  below,   to  include  in  such  Piggyback
Registration  all  Registrable  Securities with respect to which the Company has
received  written  requests for inclusion  therein within thirty (30) days after
the receipt of the Company's notice. Except as may otherwise be provided in this
Agreement,  Registrable  Securities  with  respect  to which  such  request  for
Registration  has been received will be registered by the Company and offered to
the public on the same terms and subject to the same  conditions  applicable  to
the  Piggyback  Registration  to be sold by the Company or by the other  Persons
selling under such Piggyback Registration.

         (b) Priority on Piggyback  Registrations.  If a Piggyback  Registration
relates to an underwritten offering and the managing underwriter or underwriters
advise  the  Company  in  writing  that in its or their  opinion  the  number of
securities  proposed to be sold in a Piggyback  Registration  exceeds the number
which can be sold in such offering within a price

                                        5


<PAGE>
<PAGE>



range  acceptable  to  the  Company  or  the  other  Persons  exercising  demand
registration rights, the Company will include in such Piggyback Registration the
number of securities  which, in the opinion of such underwriter or underwriters,
can be sold within such price  range,  which  securities  shall be  allocated as
follows:  (w)  first,  the  securities  proposed  to be  sold by  other  Persons
exercising  demand  registration  rights granted on or prior to the date hereof,
(x) second,  so long as the Senior  Indebtedness  (as defined in the Memorandum)
remains  outstanding,  up to an aggregate of 250,000 shares of Common Stock held
by the Bank Lenders,  provided,  that such priority shall be effective for up to
only two such  Piggyback  Registration  opportunities,  (y)  third,  Registrable
Securities  held by the Holder and  requested  to be included in such  Piggyback
Registration,  together  with any other  securities  requested to be included in
such Piggyback  Registration by other holders, pro rata among the Holder and the
other  holders  of  Registrable  Securities  (on  the  basis  of the  amount  of
Registrable  Securities then owned by each such holder) requested to be included
in such  Piggyback  Registration,  and (z) fourth,  the  securities  the Company
proposes to sell.

         (c)  Underwriting.  If a Piggyback  Registration  for which the Company
gives notice is for a registered public offering involving an underwriting,  the
Company shall so advise the Holder in the notice given pursuant to Section 3(a),
which notice shall include the name of the managing underwriter or underwriters.

         4. Demand Registration Rights.

         (a) Right to Demand.  At any time on or before the Expiration Date, the
holders  of  not  less  than  a  majority  of the  Registrable  Securities  then
outstanding  may make up to two  written  requests  (provided  in each case such
holders have not registered  Registrable  Securities  pursuant to Section 2 or 3
above  within 120 days prior to such  request) to the  Company for  registration
with  the  Commission  under  and  in  accordance  with  the  provisions  of the
Securities  Act of not less  than  $250,000  of the  Registrable  Securities  (a
"Demand Registration").  Within ten (10) days after receipt of such request, the
Company shall give written  notice of such requested  registration  to all other
holders of Registrable  Securities,  and, subject to the priority provisions set
forth in Section 4(b) below,  will include in such  registration all Registrable
Securities with respect to which the Company has received  written  requests for
inclusion  within thirty (30) days after the Company  gives such notice.  Unless
expressly agreed to by the Holder,  no securities of the Company or of any other
Person  other  than  Registrable  Securities  shall  be  included  in  a  Demand
Registration  except  pursuant  to the  exercise of any  piggyback  registration
rights  granted on or prior to the date  hereof.  Except as  otherwise  provided
herein,  a  registration  will not count as a Demand  Registration  until it has
become effective and the holders of the Registrable  Securities included in such
registration are legally permitted to sell all of their  Registrable  Securities
that  are  requested  to  be so  included  unless  the  holders  of  Registrable
Securities included in such Demand Registration fail to take such actions as are
required on their part to cause the registration to become  effective,  in which
case such registration shall count as a Demand Registration.

                                        6

         (b) Priority on Demand  Registrations.  If the managing  underwriter or
underwriters of a Demand  Registration advise the Company in writing that in its
or their  opinion  the number of  securities  proposed to be sold in such Demand
Registration exceeds the number which can be sold in such offering,  the Company
will include in such Demand Registration only the number of securities which, in
the opinion of such  underwriter or  underwriters,  can be sold in such offering
which  securities  shall be allocated on a pro rata basis among the  Registrable
Securities  and such other  securities  requested  to be included in such Demand
Registration  pursuant to the  exercise  of any  piggyback  registration  rights
granted on or prior to the date hereof.

         (c)  Selection  of  Underwriters.  If  any  Demand  Registration  is an
underwritten  offering,  a majority in  interest  of the  Holders  will select a
managing  underwriter or  underwriters to administer the offering which managing
underwriter or underwriters shall be of nationally recognized standing and shall
be reasonably acceptable to the Company; provided,  however, that the holders of
Registrable Securities  acknowledge that Commonwealth  Associates has a right of
first refusal to act as  underwriter  in connection  with any offering of Common
Stock if the terms offered by  Commonwealth  Associates  are comparable to those
being offered by other investment banking firms to similarly-situated companies,
and hereby  consent to the use of  Commonwealth  Associates  as  underwriter  in
connection with any Demand Registration.

         5. Registration  Procedures.  With respect to any Registration pursuant
to the exercise of rights provided by Sections 2, 3 and 4 of this Agreement, the
Company will (subject to Sections 2(a) and 12 hereof) promptly:

          (a) prepare and file with the Commission a  Registration  Statement (a
     "Registration Statement") which includes the Registrable Securities and use
     its best efforts to cause such  Registration  Statement to become effective
     as promptly as  practicable;  provided  that before  filing a  Registration
     Statement or any  amendments  thereto or any  Prospectus,  the Company will
     furnish  to one  counsel  selected  by the  holders  of a  majority  of the
     Registrable  Securities to be included and the underwriters,  if any, draft
     copies  of all such  documents  proposed  to be  filed  at  least  five (5)
     business  days  prior  thereto,  which  documents  will be  subject  to the
     reasonable  review of such counsel and  underwriters,  and the Company will
     not file any Registration  Statement or amendment thereto or any Prospectus
     to which a majority of such holders shall reasonably  object (provided that
     nothing herein shall prevent the Company from making a timely filing of any
     report required to be filed by it pursuant to the Exchange Act in such form
     as it determines is appropriate) and will notify the holders of Registrable
     Securities  of any stop order issued or  threatened  by the  Commission  in
     connection  therewith and take all reasonable  actions  required to prevent
     the entry of such stop order or to remove it if entered;

          (b)  prepare  and  file  with  the  Commission   such  amendments  and
     post-effective amendments to the Registration Statement as may be necessary
     to keep the Registration  Statement effective for a period of not less than
     four (4) months (or such  shorter  period  which  will  terminate  when all
     Registrable  Securities  covered by such  Registration  Statement have been
     sold or withdrawn, but not prior to the expiration of any applicable period
     referred to in Section

                                        7


<PAGE>
<PAGE>



     4(3) of the Securities Act and Rule 174 thereunder,  if applicable, or such
     longer period pursuant to Section 2(a) hereof);  cause the Prospectus to be
     supplemented by any required Prospectus supplement,  and as so supplemented
     to be filed pursuant to Rule 424 under the Securities  Act; and comply with
     the  provisions of the  Securities Act applicable to it with respect to the
     disposition of all securities covered by such Registration Statement during
     the  applicable   period  in  accordance  with  the  intended   methods  of
     disposition by the sellers thereof set forth in such Registration Statement
     or Prospectus supplement;

          (c)  furnish  to  each  seller  of  Registrable   Securities  and  the
     underwriter  or  underwriters,  if any,  at least  one  signed  copy of the
     Registration  Statement  and any  post-effective  amendment  thereto,  upon
     request,  and such number of  conformed  copies  thereof and such number of
     copies of the Prospectus (including each preliminary  Prospectus),  and any
     documents  incorporated by reference therein, as such seller or underwriter
     may  reasonably  request  in order to  facilitate  the  disposition  of the
     Registrable  Securities being sold by such seller (it being understood that
     the Company  consents to the use of the  Prospectus  by such seller and the
     underwriter or  underwriters,  if any, in connection  with the offering and
     sale of the Registrable Securities covered by the Prospectus);

          (d) notify each seller of  Registrable  Securities  at any time when a
     Prospectus  relating to Registrable  Securities is required to be delivered
     under the Securities  Act, when the Company  becomes aware of the happening
     of any  event  as a  result  of  which  the  Prospectus  included  in  such
     Registration Statement (as then in effect) contains any untrue statement of
     a material  fact or omits to state a material  fact  necessary  to make the
     statements  therein  (in the  case  of the  Prospectus  or any  preliminary
     Prospectus,  in light of the circumstances  under which they were made) not
     misleading  and, as promptly as  practicable  thereafter,  prepare and file
     with the  Commission  and make  available a supplement or amendment to such
     Prospectus  so that,  as  thereafter  delivered to the  purchasers  of such
     Registrable  Securities,  such  Prospectus  will  not  contain  any  untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements therein, in light of the circumstances under which they
     were made, not misleading;

          (e) use its best  efforts to cause all  Registrable  Securities  to be
     listed,  by the date such  Registrable  Securities  cease to be Registrable
     Securities as a result of  Registration  or otherwise,  on each  securities
     exchange or national  quotation  system on which the Shares are then listed
     or proposed to be listed, if any;

          (f) make  generally  available  to its  security  holders an  earnings
     statement  satisfying the provisions of Section 11(a) of the Securities Act
     no later than 45 days after the end of the 12-month  period  beginning with
     the first day of the Company's  first fiscal quarter  commencing  after the
     effective date of the  Registration  Statement,  which  earnings  statement
     shall cover said 12-month period; provided, however, that in the event that
     the first day of the Company's  first fiscal quarter  commencing  after the
     effective date of the Registration Statement shall also be the first day of
     the Company's fiscal year, such earnings  statement shall be made generally
     available no later than 90 days after the end of such 12-month period;

                                        8


<PAGE>
<PAGE>




          (g) use its  best  efforts  to  obtain  the  withdrawal  of any  order
     suspending the effectiveness of the Registration  Statement at the earliest
     possible moment;

          (h) if requested by the managing  underwriter or  underwriters  or any
     holder of  Registrable  Securities,  promptly  incorporate  in a Prospectus
     supplement or  post-effective  amendment  such  information as the managing
     underwriter or underwriters or such holder requests to be included  therein
     with  respect to the number of  Registrable  Securities  being sold by such
     holder to such underwriter or  underwriters,  the purchase price being paid
     therefor by such  underwriter or underwriters and with respect to any other
     terms of the underwritten offering of the Registrable Securities to be sold
     in such offering; and promptly make all required filings of such Prospectus
     supplement or post-effective amendment;

          (i) as promptly as practicable after filing with the Commission of any
     document which is incorporated by reference into a Registration  Statement,
     deliver a copy of such document to each holder of Registrable Securities;

          (j) on or prior to the date on which  the  Registration  Statement  is
     declared  effective,  use its best  efforts to  register  or  qualify,  and
     cooperate with the holders of a majority of the Registrable Securities, the
     underwriter or underwriters,  if any, and their counsel, in connection with
     the registration or qualification of the Registrable  Securities covered by
     the Registration  Statement for offer and sale under the securities or blue
     sky laws of each state and other  jurisdiction  of the  United  States as a
     majority of the such holders or underwriter reasonably requests in writing,
     to use its best  efforts to keep each such  registration  or  qualification
     effective, including through new filings, or amendments or renewals, during
     the period such  Registration  Statement  is required to be kept  effective
     pursuant to Section  5(b) hereof and to do any and all other acts or things
     necessary or advisable to permit the disposition in all such  jurisdictions
     of  the  Registrable  Securities  covered  by the  applicable  Registration
     Statement;

          (k)  cooperate  with the  holders of  Registrable  Securities  and the
     managing  underwriter  or  underwriters,  if any, to facilitate  the timely
     preparation  and  delivery of  certificates  (not  bearing any  restrictive
     legends)  representing   Registrable   Securities  to  be  sold  under  the
     Registration   Statement   and  enable  such   securities  to  be  in  such
     denominations  and registered in such names as the managing  underwriter or
     underwriters, if any, or any such holder may request;

          (l) use its best efforts to cause the Registrable  Securities  covered
     by the  Registration  Statement to be  registered  with or approved by such
     other governmental  agencies or authorities within the United States as may
     be  necessary  to enable  such  holder  of  Registrable  Securities  or the
     underwriter or underwriters,  if any, to consummate the disposition of such
     Registrable Securities;

          (m) enter into such customary  agreements  (including an  underwriting
     agreement in customary form) and take all such other actions as the holders
     of a majority of the Registrable

                                        9


<PAGE>
<PAGE>



     Securities being sold or the underwriters retained by such holders, if any,
     reasonably  request in order to expedite or facilitate  the  disposition of
     such Registrable Securities;

          (n) make available for inspection by a  representative  of the sellers
     of Registrable Securities, any underwriter participating in any disposition
     pursuant to such Registration  Statement,  and any attorney,  accountant or
     other agent retained by any such seller or underwriter  (collectively,  the
     "Inspectors"),   all  financial  and  other  records,  pertinent  corporate
     documents  and  properties  of the  Company  and its  direct  and  indirect
     subsidiaries (collectively, the "Records") as shall be reasonably necessary
     to enable them to exercise  their due diligence  reasonably,  and cause the
     Company's  officers,  directors  and  employees  to supply all  information
     reasonably  requested  by any  such  Inspectors  in  connection  with  such
     Registration  Statement;  provided  that  the  Records  which  the  Company
     determines,  in good faith,  to be  confidential  and which it notifies the
     Inspectors are confidential shall not be disclosed to the Inspectors unless
     (x) the  disclosure  of such  Records  is  necessary  to avoid or correct a
     misstatement or omission in the  Registration  Statement or (y) the release
     of such  Records is ordered  pursuant  to a subpoena  or other order from a
     court of competent jurisdiction;  provided,  however, that any decision not
     to  disclose  information  pursuant  to  clause  (x)  shall  be made  after
     consultation with counsel for the Company,  and such  representative of the
     sellers agrees that it will,  upon learning that disclosure of such Records
     is sought in a court of competent jurisdiction,  give notice to the Company
     and allow the Company, at the Company's expense,  to undertake  appropriate
     action to prevent disclosure of the Records deemed confidential;

          (o) use its best  efforts  to obtain a cold  comfort  letter  from the
     Company's  independent  public  accountants  in customary form and covering
     such matters of the type  customarily  covered by cold comfort letters as a
     representative of the sellers of Registrable Securities reasonably request;
     and

          (p) furnish each seller of Registrable  Securities  with an opinion of
     its counsel  (reasonably  acceptable to such seller) to the effect that (i)
     such  registration  statement has become effective under the Securities Act
     and no order suspending the effectiveness of such  registration  statement,
     preventing  or  suspending  the use of  such  registration  statement,  any
     preliminary  prospectus,   any  final  prospectus,   or  any  amendment  or
     supplement  thereto  has  been  issued,  nor  has  the  SEC  instituted  or
     threatened to institute any proceedings with respect to such an order, (ii)
     such  registration  statement  and each  prospectus  forming a part thereof
     (including each  preliminary  prospectus),  and any amendment or supplement
     thereto,  complies  as to form  with the  Securities  Act and the rules and
     regulations  thereunder,  and (iii) such  counsel has no  knowledge  of any
     material  misstatement  or omission in such  registration  statement or any
     prospectus,  as amended or supplemented except no opinion need be expressed
     as to the financial statements and related schedules,  and counsel shall be
     entitled to rely on opinions of other counsel  reasonably  satisfactory  to
     such sellers regarding matters of foreign law and intellectual property.

         The  Holder,  upon  receipt  of any  notice  from  the  Company  of the
happening of any event of the kind  described in Section  5(d),  will  forthwith
discontinue disposition of the Registrable Securities until the Holder's receipt
of the copies of the supplemented or amended Prospectus  contemplated by Section
5(d) or until it is advised in writing  (the  "Advice")  by the Company that the
use of the Prospectus may be resumed,  and has received copies of any additional
or supplemental  filings which are  incorporated by reference in the Prospectus,
and,  if so  directed  by the  Company,  the Holder  will,  or will  request the
managing  underwriter  or  underwriters,  if any,  to deliver to the Company all
copies, other than permanent file copies then in the Holder's possession, of the
Prospectus  covering such Registrable  Securities at the time of receipt of such
notice.  In the event the Company  shall give any such  notice,  the time period
mentioned  in Section  5(b) shall be  extended  by the number of  business  days
during the period  from and  including  the date of the giving of such notice to
and  including  the date when the Holder  shall have  received the copies of the
supplemented or amended Prospectus contemplated by Section 5(d) or the Advice.

         The Holder shall furnish to the Company such information  regarding the
Registrable Securities held by it and the intended method of disposition thereof
and other  information  concerning  the Holder as the Company  shall  reasonably
request and as shall be required in connection with the  Registration  Statement
to be filed by the Company.

         6. Holdback Arrangements.

         (a) Restrictions on Public Sale by Holder of Registrable Securities. To
the extent not inconsistent with applicable law, the Holder agrees not to effect
any public sale or distribution of the securities  being registered or a similar
security of the Company,  or any securities  convertible into or exchangeable or
exercisable for such  securities,  including a sale pursuant to Rule 144 or Rule
144A  under the  Securities  Act,  during and not  exceeding  180 days after the
effective  date  of  a  Registration   Statement  relating  to  an  underwritten
Registration of Registrable  Securities,  as may be reasonably  requested by the
managing  underwriter  or  underwriters,  except  as part  of such  Registration
Statement.

         (b) Restrictions on Public Sale by the Company.  The Company agrees (x)
not to effect any public sale or distribution of any securities similar to those
being  registered,  or  any  securities  convertible  into  or  exchangeable  or
exercisable  for such  securities  (other than any such sale or  distribution of
such  securities in connection  with any merger or  consolidation  involving the
Company  or a  subsidiary  thereof  or  the  acquisition  by  the  Company  or a
subsidiary  thereof of the capital equity or substantially  all of the assets of
any other Person or with respect to any employee benefit or stock plan),  during
the fourteen  (14) days prior to, and during such period not  exceeding 180 days
after the effective date of any  Registration  Statement  except as part of such
Registration  Statement;  and (y) that any agreement entered into after the date
of this  Agreement  pursuant to which the Company  issues or agrees to issue any
privately  placed  securities  shall contain a provision  under which holders of
such securities  agree not to effect any public sale or distribution of any such
securities  during the period  described in (x) above,  in each case including a
sale pursuant to Rule 144 or Rule 144A under the Securities Act (except

                                       11


<PAGE>
<PAGE>



as part of any such registration,  if permitted);  provided,  however,  that the
provision of this Section 6(b) shall not prevent the  conversion  or exchange of
any securities pursuant to their terms as in effect prior to the commencement of
such period into or for other securities.

         (c)  Other  Registrations.  If  the  Company  has  previously  filed  a
Registration  Statement  with  respect to  Registrable  Securities,  and if such
previous registration has not been withdrawn or abandoned,  the Company will not
file or cause to be effective  any other  registration  of any of the Shares (or
securities convertible into or exchangeable or exercisable for the Shares) under
the Securities Act (except on Form S-4 or S-8 or any successor forms or filed in
connection  with an exchange  offer or an offering of  securities  solely to the
Company's existing employees or security holders),  whether on its own or at the
request of any holder or holders of the Shares (or securities  convertible  into
or exchangeable  or exercisable for the Shares),  until a period of at least 120
days has elapsed from the effective date of such previous registration (provided
that in the case of a Demand Registration such period shall commence on the date
the Company is first served the notice of demand registration and shall continue
until at least 180 days have  elapsed  from the  effective  date of such  Demand
Registration).

         7. Indemnification; Contribution.

         (a) Indemnification by the Company. The Company agrees to indemnify and
hold harmless each holder of  Registrable  Securities  and each of such holder's
officers, directors and agents and each Person, if any, who controls a holder of
Registrable Securities within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act (each, an "Indemnitee")  from and against any and
all losses,  claims,  damages,  liabilities and expenses  (including  reasonable
attorneys'  fees and costs of  investigation)  arising  out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration  Statement  or  Prospectus,  or  arising  out of or based  upon any
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or  necessary  to make the  statements  therein not  misleading,
except insofar as such losses,  claims,  damages,  liabilities or expenses arise
out of or are based upon information  with respect to such Indemnitee  furnished
in writing to the Company by such  Indemnitee  expressly for use therein.  It is
agreed that the  indemnification  agreement contained in this Section 7(a) shall
not apply to  amounts  paid in  settlement  of any such loss,  claim,  damage or
liability  if such  settlement  is  effected  without the consent of the Company
(which consent has not been unreasonably  withheld).  The Company also agrees to
indemnify  any  underwriters  on  substantially  the  same  basis as that of the
indemnification  of the  holders  of  Registrable  Securities  provided  in this
Section 7(a).

                                       12


<PAGE>
<PAGE>



         (b) Conduct of Indemnification Proceedings. If any action or proceeding
(including any governmental  investigation) shall be brought or asserted against
the holders of Registrable Securities (or its officers,  directors or agents) or
any Person  controlling  any such  holder in respect of which  indemnity  may be
sought from the Company, the Company shall be permitted to assume the defense of
such claim,  unless in the reasonable  judgment of such Indemnitee a conflict of
interest may exist between such  Indemnitee and the Company with respect to such
claim or differing or additional  defenses may be available to such  Indemnitee.
If defense of a claim is assumed by the Company, Indemnitees shall not be liable
for any  settlement of such action or proceedings  effected  without their prior
written consent.  The Company will not consent to entry of any judgment or enter
into any settlement which does not include as an unconditional  term thereof the
giving by the  claimant or plaintiff  to such  Indemnitee  of a release from all
liability in respect of such claim or litigation. If the Company is not entitled
to, or elects not to, assume the defense of a claim, it will not be obligated to
pay the fees and  expenses  of more than one counsel  for the  Indemnitees  as a
group  with  respect  to such  claim  in each  jurisdiction  in which a claim is
brought,  unless in the  reasonable  judgment  of any  Indemnitee  a conflict of
interest may exist between such Indemnitee and any other Indemnitee with respect
to such claim or  differing  or  additional  defenses  may be  available to such
Indemnitee,  in which event the Company  shall be  obligated to pay the fees and
expenses  of such  additional  counsel.  Each holder of  Registrable  Securities
agrees to give prompt  written  notice to the  Company  after its receipt of any
written  notice  of  the  commencement  of  any  action,  suit,  proceedings  or
investigation  or threat thereof made in writing for which such holder may claim
indemnification or contribution pursuant to this Agreement;  provided,  however,
that  failure  to give such  notice  shall not limit the  Indemnitee's  right to
indemnification  or  contribution  hereunder  unless and to the extent  that the
Company did not otherwise  learn of such action and such failure  results in the
forfeiture by it of substantial rights and defenses.

         (c)  Indemnification  by  the  Holders.   Each  holder  of  Registrable
Securities agrees to indemnify and hold harmless the Company, and its directors,
officers and agents and each Person, if any, who controls the Company within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same  extent as the  foregoing  indemnity  from the  Company  to such
holder but only with respect to information  furnished in writing by such holder
with respect to such holder which  contained a material  misstatement of fact or
omission of a material fact expressly for use in any  Registration  Statement or
any amendment thereto or any Prospectus,  or any preliminary Prospectus relating
to the Registrable Securities. In case any action or proceeding shall be brought
against  the  Company,  each  holder of  Registrable  Securities  or any of such
holder's  respective  directors,  officers  or agents,  or any such  controlling
Person,  in respect of which  indemnity may be sought against such holder,  such
holder shall have the rights and duties  given to the Company,  and the Company,
or its directors,  officers or agents or such controlling Person, shall have the
rights and duties given to such holder by Section 7(b).

         (d) Contribution. If the indemnification provided for in this Section 7
is  unavailable  to the Company,  the holders of  Registrable  Securities or the
underwriters in respect to any losses, claims, damages, liabilities or judgments
referred to herein,  then each such indemnifying  party, in lieu of indemnifying
such indemnified  party,  shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims,  damages,  liabilities and
judgments in such  proportion as is appropriate to reflect the relative fault of
the  indemnifying  parties  and  indemnified  parties  in  connection  with such
statements  or  omissions  which  resulted  in  the  losses,  claims,   damages,
liabilities   or   judgments,   as  well  as  any   other   relevant   equitable
considerations.  The relative fault of such  indemnifying  party and indemnified
parties shall be  determined  by reference  to, among other things,  whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity to correct or prevent such statement or omission.

         The  Company and the holders of  Registrable  Securities  agree that it
would not be just and  equitable if  contribution  pursuant to this Section 7(d)
were  determined  by pro rata  allocation  or by any other method of  allocation
which does not take account of the equitable  considerations  referred to in the
immediately  preceding  paragraph.  The amount paid or payable by an indemnified
party as a result of the  losses,  claims,  damages,  liabilities  or  judgments
referred to in the immediately  preceding  paragraph shall be deemed to include,
subject  to the  limitation  set  forth  above,  any  legal  or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or  defending  any  such  action  or  claim.  No  Person  guilty  of  fraudulent
misrepresentations  (within the meaning of Section 11(f) of the Securities  Act)
shall be  entitled  to  contribution  from any Person who was not guilty of such
fraudulent  misrepresentations.  For the  purposes of this  Section  7(d),  each
director of the Company, each officer who signed the Registration  Statement and
each Person,  if any, who controls the Company  within the meaning of Section 15
of the Securities Act shall have the same rights to contribution as the Company.

         8.   Participation   in  Underwritten   Registrations.   No  holder  of
Registrable   Securities  may  participate  in  any  underwritten   Registration
hereunder (which shall be conducted in accordance with the provisions of Section
2, 3 or 4) unless  such  holder  (i)  agrees to sell such  holder's  Registrable
Securities  on the basis  provided in any  customary  underwriting  arrangements
(approved by the holders of Registrable  Securities as provided herein) and (ii)
completes  and executes  all  questionnaires,  powers of attorney,  underwriting
agreements  and  other  documents  reasonably  required  under the terms of such
underwriting arrangements and these registration rights; provided, however, such
holder shall not be required to make  representations  or give  indemnifications
except  with  respect  to  information  provided  in  writing  by the  holder of
Registrable Securities concerning such holder and its plan of distribution.

         9. Rule  144.  The  Company  covenants  that it will  file any  reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations  adopted by the Commission  thereunder (or, if the Company
is not required to file such reports,  it will,  upon the request of the holders
of Registrable Securities,  make publicly available other information so long as
necessary to permit sales under Rule 144 under the Securities Act), that it will
take such further action as the holders of Registrable Securities may reasonably
request,  all to the extent required from time to time to enable such holders to
sell Registrable Securities without registration under the Securities Act within
the limitations of the exemptions  provided by (i) Rule 144 under the Securities
Act, as such rule may be amended from time to time,  or (ii) any similar rule or
regulation hereafter adopted by the Commission.  Upon the request of the holders
of  Registrable  Securities,  the  Company  will  deliver to each such  holder a
written  statement as to whether it has complied with the  requirements  of this
Section 9.

         10.  Registration  Expenses.  The Registration  Expenses related to the
Shelf  Registration,  first Demand  Registration and any Piggyback  Registration
shall be borne solely by the Company.

         11. Stand-Off and Special Audit.

         (a) Stand-Off.  If at the time of any request for a Demand Registration
pursuant  to Section 4, the Company (i) is engaged or has fixed plans to engage,
within  thirty  (30) days of the time of the  request,  in a  registered  public
offering  as to which the holders of  Registrable  Securities  may,  pursuant to
Section 4, include all Registrable  Securities  proposed to be sold by them, and
which in fact becomes  effective  within 90 days after the  request,  or (ii) is
engaged in any other  activity  which,  in the good faith  determination  of the
Company's  board  of  directors,  would  be  adversely  affected  by the  Demand
Registration to the material  detriment of the Company,  then the Company may at
its option  direct  that such  request be delayed for a period not to exceed six
(6) months from the effective date of such offering or the date of  commencement
of such other material  activity,  as the case may be, provided that each holder
of Registrable Securities has had no other request delayed during the six months
prior to such request.

         (b) Provisions for Special Audit.  In the event that a special audit of
the Company's  financial  statements  would be required to effect a Registration
pursuant  to  Section  4, the  Company  shall  promptly  notify  each  holder of
Registrable  Securities  that a special audit is required.  In such event,  such
holders   shall  have  the  right  to  either  (i)  withdraw  such  request  for
Registration, in which case the request shall not count as a Demand Registration
to which such holders are entitled under this Agreement or (ii) pay the expenses
of conducting the special audit.

         12.  Public  Trading  Market.  Until the earlier of (a) three (3) years
after  the  date  hereof  or (b) the  date on  which  there  are no  Registrable
Securities,  the Company shall use its best efforts to maintain a public trading
market for its Shares.

any of its properties or assets is bound,  or conflict with,  result in a breach
of or constitute  (with due notice or lapse of time or both) a default under any
such  indenture,  agreement  or other  instrument,  or result in the creation or
imposition of any lien,  charge or encumbrance of any nature whatsoever upon any
of the properties or assets of the Company.

         (b) This Agreement has been duly executed, and delivered by the Company
and  constitutes  the  legal,  valid  and  binding  obligation  of the  Company,
enforceable in accordance with its terms.

         14. Miscellaneous.

         (a) Other  Registration  Rights.  Except as provided in the Memorandum,
the Company does not have and shall not grant  registration  rights with respect
to any  securities  of the Company to any Person that are  superior  to, or that
adversely affect, the registration  rights granted to the holders of Registrable
Securities  pursuant to this  Agreement.  The  Company  shall not enter into any
agreement inconsistent with any of the provisions hereof.

         (b)  Amendments.  This Agreement may not be amended without the written
consent of the Company and a majority of the holders of Registrable Securities.

         (c) Successors and Assigns. The Company may not sell, assign,  transfer

Agreement,  except to a corporation  which has succeeded to substantially all of
the  business  and  assets  of the  Company  and  has  assumed  in  writing  its
obligations  under this  Agreement,  and this Agreement  shall be binding on the
Company and such  successor.  This Agreement  shall be binding upon and inure to
the benefit of and be  enforceable by the Holder and its successors and assigns.
Without limiting the generality of the foregoing,  any transferee of Registrable
Securities  shall have the rights set forth in this  Agreement,  and such rights
shall be  enforceable  against the Company by such  transferees  as  third-party
beneficiaries.

         (d)  Notices.  All  notices  and  other  communications   provided  for
hereunder shall be given and shall be effective as provided in the Warrant.

         (e)  Descriptive  Headings.  The  headings  in this  Agreement  are for

         (f) Severability.  In the event that any one or more of the provisions,
paragraphs,  words,  clauses,  phrases or  sentences  contained  herein,  or the
application  thereof  in  any  circumstances,   is  held  invalid,   illegal  or
unenforceable  in any  respect  for  any  reason,  the  validity,  legality  and
enforceability of such provision, paragraph, word, clause, phrase or sentence in
every other respect and of the remaining provisions, paragraphs, words, clauses,
phrases or sentences hereof shall not be in any way impaired,  it being intended
that  all  rights,  powers  and  privileges  of  the  parties  hereto  shall  be
enforceable to the fullest extent permitted by law.

         (g)  Counterparts.  This  Agreement  may be  executed  in  two or  more
counterparts,  each of which shall be deemed an original, but all of which shall
constitute one and the same instrument,  and it shall not be necessary in making
proof  of  this  Agreement  to  produce  or  account  for  more  than  one  such
counterpart.

         (h) Governing  Law. THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED
AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

         (i)  Remedies.   Without   affecting  the  rights  of  holders  of  the
Registrable  Securities in any way pursuant to Section 2(d) hereof,  the Company
acknowledges  that monetary  damages will not be adequate  compensation  for any
loss incurred by reason of a breach by it of the  provisions  hereof and agrees,
to the  fullest  extent  permitted  by law,  to waive the defense of adequacy of
legal remedies in any action for specific performance hereof.

         (j) Merger,  etc. If,  directly or  indirectly,  (i) the Company  shall
merge with and into, or  consolidate  with,  any other  Person,  (ii) any Person

Securities  shall be changed into or exchanged for stock or other  securities of
any other Person,  then, in each such case,  proper  provision  shall be made so
that such Person shall be bound by the provisions of this Agreement and the term
"Company" shall thereafter be deemed to refer to such Person.

Registration  Rights  Agreement  to be  signed  on its  behalf as of this ______
day of February 1996.

Attention:   Mr. Keith M. Rosenbloom
               Vice President - Corporate Finance

Gentlemen:

         NAI  Technologies,  Inc.,  a  New  York  corporation  (the  "Company"),
proposes to offer for sale to "accredited investors," in a private placement, up
to 9,200 units (the "Units") for a purchase price of $1,000 per Unit.  Each Unit
consists  of (i)  $1,000  principal  amount  of the  Company's  12%  Convertible
Subordinated Promissory Notes due 2001 (the "Notes"),  convertible at the option
of the holder at any time into 500 shares of the  Company's  Common  Stock,  par
value $.10 per share (the "Common Stock"), and (ii) a warrant (the "Warrant") to
purchase  250  shares of Common  Stock at an  exercise  price of $2.50 per share
(subject to adjustment in certain  events) from the date issuance until February
15,  2002.  The Units will be offered  pursuant  to those  terms and  conditions
acceptable to you as reflected in the Confidential Private Placement Memorandum,
dated December 15, 1995, as supplemented (the  "Memorandum").  The Units will be
offered on a "best  efforts,  6,000  Units-or-none"  basis and after 6,000 Units
have been  sold,  the  remaining  Units will be sold on a "best  efforts"  basis
pursuant to the Memorandum and related documents in accordance with Section 4(2)
of the Securities Act of 1933, as amended (the "Securities Act"), and Regulation
D promulgated thereunder.

         Commonwealth   Associates  is  sometimes  referred  to  herein  as  the
"Placement  Agent." The Memorandum,  as it may be amended or  supplemented  from
time to time, the form of proposed  subscription  agreement  between the Company
and each subscriber (the "Subscription  Agreement") and the other exhibits which
are part of the Memorandum  and/or the  Subscription  Agreement are collectively
referred to herein as the "Offering Documents."

         The  Company  will  prepare  and  deliver  to  the  Placement  Agent  a
reasonable  number of copies of the  Offering  Documents  in form and  substance
satisfactory to counsel to the Placement Agent.


<PAGE>
<PAGE>



         Each   prospective   investor   subscribing   to   purchase   Units  (a
"Subscriber")  will be required to deliver,  among other things,  a Subscription
Agreement and an offeree  questionnaire  (a  "Questionnaire")  in the form to be
provided to offerees.

         1. Appointment of Placement Agent.

         (a) You are hereby appointed  exclusive  Placement Agent of the Company
during the Offering  Period  herein  specified for the purposes of assisting the
Company  in  finding  qualified   Subscribers  pursuant  to  the  offering  (the
"Offering")  described in the  Offering  Documents.  The  Offering  Period shall
commence  on the day the  Offering  Documents  are first made  available  to the
Placement  Agent by the Company for delivery in connection with the Offering for
sale of the Units and shall  continue until the earlier to occur of (i) the sale
of all of the Units or (ii) February 15, 1996 (unless  extended until a date not
later  than  30  days  thereafter  under  the  circumstances  specified  in  the
Memorandum). The day that the Offering Period terminates is hereinafter referred
to as the "Termination Date."

         (b) Subject to the performance by the Company of all of its obligations
to be performed under this Agreement and to the completeness and accuracy of all
representations  and warranties of the Company contained in this Agreement,  the
Placement Agent hereby accepts such agency and agrees to use its best efforts to
assist the Company in finding  qualified  subscribers  pursuant to the  Offering
described in the Offering  Documents.  It is understood that the Placement Agent
has no commitment to sell the Units.  Your agency hereunder is not terminable by
the Company except upon termination of the Offering Period.

         (c)  Subscriptions  for Units shall be  evidenced  by the  execution by
Subscribers of a Subscription  Agreement.  No  Subscription  Agreement  shall be
effective unless and until it is accepted by the Company.  Until the Closing (as
such term is defined in Section 4(b) hereof),  all  subscription  funds received
shall be held as described  in the  Subscription  Agreement  and in Section 4(a)
hereof.  The  Placement  Agent shall not have any  obligation  to  independently
verify  the  accuracy  or  completeness  of  any  information  contained  in any
Subscription Agreement or the authenticity, sufficiency or validity of any check
delivered by any prospective investor in payment for Units.

         2.   Representations  and  Warranties  of  the  Company.   The  Company
represents and warrants to the Placement Agent as follows:

          (a) Securities Law Compliance.  The Offering  Documents conform in all
     respects with the  requirements  of Section 4(2) of the  Securities Act and
     Regulation D promulgated  thereunder and with the requirements of all other
     published rules and  regulations of the Securities and Exchange  Commission
     (the "Commission")  currently in effect relating to "private  offerings" to
     "accredited  investors." The Offering  Documents,  when read together as of
     their respective  dates, will not contain an untrue statement of a material
     fact or omit to state  any  material  fact  necessary  in order to make the
     statements  therein, in light of the circumstances in which they were made,
     not misleading. If at any time prior to the Termination Date or other

<PAGE>



     termination of this Agreement any event shall occur as a result of which it
     might become  necessary to amend or  supplement  the Offering  Documents so
     that they do not include any untrue  statement of any material fact or omit
     to state  any  material  fact  necessary  in  order to make the  statements
     therein,  in the light of the circumstances then existing,  not misleading,
     the Company will promptly  notify the  Placement  Agent and will supply the
     Placement Agent with amendments or supplements correcting such statement or
     omission. The Company will also provide the Placement Agent for delivery to
     all  offerees  and  purchasers  and  their  representatives,  if  any,  any
     information,  documents and  instruments  which the  Placement  Agent deems
     necessary to comply with applicable state and federal law.

          (b) Organization.  Each of the Company and Codar, Systems, Lynwood and
     Wilcom (as such terms are defined in the Memorandum) is a corporation  duly
     organized,  validly  existing  and in good  standing  under the laws of its
     respective  state or  jurisdiction of  incorporation  and has all requisite
     corporate power and authority to own and lease its properties,  to carry on
     its business as currently  conducted  and as proposed to be  conducted,  to
     execute  and  deliver  this  Agreement  and to carry  out the  transactions
     contemplated  by this  Agreement,  and is duly  licensed or qualified to do
     business as a foreign corporation in each jurisdiction in which the conduct
     of its business or ownership or leasing of its properties requires it to be
     so qualified,  except where the failure to be so qualified would not have a
     material adverse effect on the business,  financial  condition or prospects
     of the Company.

     stock  of the  Company  prior  to  the  consummation  of  the  transactions
     contemplated  hereby  is as set forth in the  Memorandum.  All  issued  and
     outstanding  shares of the  Company  are  validly  issued,  fully  paid and
     nonassessable  and have not been  issued  in  violation  of the  preemptive
     rights of any shareholder of the Company.  All prior sales of securities of
     the Company were either  registered under the Securities Act and applicable
     state securities laws or exempt from such registration.

          (d)  Warrants,  Preemptive  Rights,  etc.  Except for the  Notes,  the
     Warrants,  the warrants to purchase  shares of Common Stock to be issued to
     the  Placement  Agent or its  designees  in  consideration  for  acting  as
     Placement Agent hereunder (the "Agent's  Warrants") and except as set forth
     in the Memorandum,  including the exhibits thereto, there are not, nor will
     there be immediately after the Closing, any outstanding warrants,  options,
     agreements,  convertible securities,  preemptive rights to subscribe for or
     other  commitments  pursuant  to  which  the  Company  is,  or may  become,
     obligated to issue any shares of its capital  stock or other  securities of
     the Company and this Offering will not cause any anti-dilution  adjustments
     to such securities or commitments except as reflected in the Memorandum.

          (e) Subsidiaries  and Investments.  Except as stated in the Memorandum
     and for Arathon V.I., Inc., the Company has no subsidiaries and the Company

          (f) Financial  Statements.  The financial information contained in the
     Offering  Documents is accurate in all material  respects  (such  financial
     statements  included  as part of the  Offering  Documents  are  hereinafter
     referred to  collectively  as the  "Financial  Statements").  The Financial
     Statements  have  been  prepared  in  conformity  with  generally  accepted
     accounting   principles   consistently   applied  and  show  all   material
     liabilities, absolute or contingent, of the Company required to be recorded
     thereon and present fairly the financial position and results of operations
     of the Company as of the dates and for the periods indicated.

          (g) SEC Documents.  The Company has furnished the Placement Agent with
     true and complete  copies of all documents  that the Company has filed with
     the  Commission  since January 1, 1995 (the "SEC  Documents").  As of their
     respective filing dates,  except as amended by filings with the Commission,
     the SEC Documents  complied in all material  respects with the requirements
     of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as
     applicable,  were  complete and correct in all material  respects as of the
     dates at which the  information  was  furnished,  and contained (as of such
     dates)  no untrue  statement  of a  material  fact nor  omitted  to state a
     material fact  necessary in order to make the statements  made therein,  in
     light of the circumstances under which they were made, not misleading.  The
     financial  statements  of the Company  included in the SEC  Documents  (the
     "Financial  Statements")  comply as to form in all material  respects  with
     applicable  accounting  requirements  and  with  the  published  rules  and
     regulations of the Commission with respect  thereto,  have been prepared in
     accordance  with  generally  accepted  accounting  principles  applied on a
     consistent basis during the periods involved (except as may be indicated in
     the notes thereto or, in the case of unaudited statements,  as permitted by
     the rules  and  regulations  of the  Commission)  and  fairly  present  the
     consolidated  financial position of the Company as of the dates thereof and
     the  consolidated  results of its  operations  and changes in its financial
     position  for the periods  then ended  (subject,  in the case of  unaudited
     statements, to normal recurring audit adjustments,  provided that the notes
     and  accounts  receivable  are  collectible  in the amounts  shown less any
     reserve shown thereon and inventories are not subject to write-down, except
     in either case in an amount not  material).  The  information  contained in
     this  Agreement and the SEC Documents is true,  complete and correct in all
     material  respects and does not contain any untrue  statement of a material
     fact or omit to state any  material  fact  required to be stated  herein or
     therein  or  necessary  to  make  the  statements  herein  or  therein  not
     misleading.

          (h)  Absence of  Changes.  Except as stated in the  Memorandum,  since
     January  1,  1995,  the  Company  has  not  incurred  any   liabilities  or
     obligations,  direct or contingent, not in the ordinary course of business,
     or entered into any  transaction  not in the  ordinary  course of business,
     which is material to the  business of the  Company,  and there has not been
     any change in the capital stock of, or any incurrence of long-term debt by,
     the  Company,  or any  issuance  of options,  warrants  or other  rights to
     purchase  the capital  stock of the Company,  or any adverse  change or any
     development involving,  so far as the Company can now reasonably foresee, a
     prospective adverse change in the condition  (financial or otherwise),  net
     worth, results of operations,  business,  key personnel or properties which
     would be material to the  business or  financial  condition of the Company,
     and the Company has not become a party to, and neither the business nor the
     property of the Company has become the subject of, any


                                        4


<PAGE>
<PAGE>



     litigation  which if  adversely  determined  would have a material  adverse
     affect, whether or not in the ordinary course of business.

          (i) Title. Except as set forth in the Memorandum, the Company has good
     and marketable  title to all  properties and assets,  owned by it, free and
     clear of all liens, charges,  encumbrances or restrictions,  except such as
     are not  materially  significant  or important in relation to the Company's
     business;  all of the material leases and subleases under which the Company
     is the  lessor or  sublessor  of  properties  or assets or under  which the
     Company holds properties or assets as lessee or sublessee are in full force
     and effect,  and the Company is not in default in any material respect with
     respect  to any of the  terms  or  provisions  of  any of  such  leases  or
     subleases,  and no material  claim has been  asserted by anyone  adverse to
     rights of the Company as lessor,  sublessor,  lessee or sublessee under any
     of the leases or subleases mentioned above, or affecting or questioning the
     right of the Company to  continued  possession  of the leased or  subleased
     premises or assets  under any such lease or  sublease.  The Company owns or
     leases  all such  properties  as are  necessary  to its  operations  as now
     conducted and to be conducted, as presently planned.

          (j) Patents,  Trademarks,  etc. The Company owns or possesses adequate
     and enforceable rights to use all patents, patent applications, trademarks,
     service  marks,  copyrights,   trade  secrets,   processes,   formulations,
     technology  or  know-how  used or proposed to be used in the conduct of its
     business  as  described  in  the  Memorandum  (collectively,   "Proprietary
     Rights").  The Company has not received any notice of any claims,  nor does
     it have any knowledge of any threatened claims, and knows of no facts which
     could  form the basis of any  claim,  asserted  by any person to the effect
     that the sale or use of any  product or process  now used or offered by the
     Company or proposed to be used or offered by the Company  infringes  on any
     patents or infringes upon the use of any such Proprietary Rights of another
     person  and,  to the  best  of the  Company's  knowledge,  no  others  have
     infringed the Company's Proprietary Rights.

          (k) Litigation.  Except as set forth in the Memorandum under "Business
     -- Legal  Proceedings," there is no material action,  suit,  investigation,
     customer  complaint,  claim or  proceeding at law or in equity by or before
     any arbitrator,  governmental  instrumentality  or other agency now pending
     or, to the  knowledge  of the Company,  threatened  against the Company (or
     basis  therefor known to the Company),  the adverse  outcome of which could
     materially  adversely  affect the  Company's  business.  The Company is not
     subject to any judgment,  order, writ, injunction or decree of any federal,
     state,  municipal  or other  governmental  department,  commission,  board,
     bureau,  agency  or  instrumentality,   domestic  or  foreign  which  could
     materially adversely affect the Company's business or prospects.

          (l) Nondefaults;  Noncontravention. The Company is not in violation of
     or default under,  nor will the execution and delivery of this Agreement or
     any  of  the  Offering   Documents  or  consummation  of  the  transactions
     contemplated  herein or therein (except for the written consent of the Bank
     Lenders)  result  in  a  violation  of  or  constitute  a  default  in  the
     performance  or  observance  of  any  obligation  (i)  under  its  Restated
     Certificate of Incorporation


                                        5

<PAGE>



     or its By-laws, (ii) under any indenture, mortgage, deed of trust, material
     contract, material purchase order or other material agreement or instrument
     to which the Company is a party or by which it or its  property is bound or
     affected or (iii) with respect to any material order,  writ,  injunction or
     decree of any court or any federal,  state, municipal or other governmental
     department, commission, board, bureau, agency or instrumentality,  domestic
     or foreign, and there exists no condition,  event or act which constitutes,
     nor which  after  notice,  the lapse of time or both,  could  constitute  a
     default  under any of the  foregoing,  which in either  case  would  have a
     material adverse effect on the business of the Company.

          (m) Taxes. The Company has filed all federal, state, local and foreign
     tax returns  which are  required to be filed by it and all such returns are
     true and correct in all material  respects.  The Company has paid all taxes
     pursuant to such returns or pursuant to any  assessments  received by it or
     which it is  obligated  to withhold  from  amounts  owing to any  employee,
     creditor  or third  party.  The  Company  has  properly  accrued  all taxes
     required  to be accrued.  The tax returns of the Company are not  currently
     being audited by any state,  local or federal  authorities,  except for the
     federal tax returns  relating to NAI for the fiscal year ended December 31,
     1994 and Codar  Technology,  Inc. (or its  predecessor) for the fiscal year
     ended  October  14,  1993.  The  Company  has not  waived  any  statute  of
     limitations  with respect to taxes or agreed to any  extension of time with
     respect to any tax assessment or deficiency.

          (n) Compliance with Laws; Licenses,  etc. The Company has not received
     notice of any violation of or noncompliance with any federal,  state, local
     or foreign  laws,  ordinances,  regulations  and orders  applicable  to its
     business which has not been cured, the violation of, or noncompliance  with
     which, would have a materially adverse effect on the business or operations
     of the  Company.  The  Company  has all  licenses  and  permits  and  other
     governmental  certificates,  authorizations  and  approvals  (collectively,
     "Licenses")  required  by every  federal,  state  and local  government  or
     regulatory  body for the  operation of its business as currently  conducted
     and the use of its  properties,  except  where the  failure to be  licensed
     would not have a material  adverse  effect on the  business of the Company.
     The  Licenses  are in full force and effect and no  violations  are or have
     been recorded in respect of any License and no proceeding is pending or, to
     the knowledge of the Company, threatened to revoke or limit any thereof.

          (o)  Authorization  of Agreement,  etc.  This  Agreement has been duly
     executed  and  delivered  by the Company and the  execution,  delivery  and
     performance by the Company of this Agreement and the Subscription Agreement
     and other  Offering  Documents  have been duly  authorized by all requisite
     corporate action by the Company and constitute the legal, valid and binding
     obligations of the Company, enforceable in accordance with their respective
     terms.

          (p)  Authorization  of Units.  The issuance,  sale and delivery of the
     Units,  the Notes,  the  Warrants and the Agent's  Warrants  have been duly
     authorized  by all requisite  corporate  action of the Company and, when so
     issued, paid for and delivered,  the Warrants will be validly issued, fully
     paid and nonassessable and, will not be subject to


                                        6


<PAGE>
<PAGE>



     preemptive or any other similar rights of the  shareholders  of the Company
     or others which rights shall not have been waived prior to the Closing.

          (q) Authorization of Reserved Shares. The issuance,  sale and delivery
     by the Company of the shares of Common Stock  reserved  for  issuance  upon
     conversion  of the Notes  and  exercise  of the  Warrants  and the  Agent's
     Warrants (the "Reserved Shares") have been duly authorized by all requisite
     corporate  action of the Company,  subject to  shareholder  approval at the
     Company's  Special  Meeting of Shareholders to be held on February 1, 1996,
     and, subject to the foregoing and the filing of the Charter  Amendment with
     the Department of State of the State of New York, the Reserved  Shares have
     been duly reserved for issuance  upon  conversion of the Notes and exercise
     of the Warrants and the Agent's Warrants and when so issued, sold, paid for
     and delivered,  the Reserved Shares will be validly issued and outstanding,
     fully paid and  nonassessable,  and not subject to  preemptive or any other
     similar  rights of the  shareholders  of the Company or others which rights
     shall not have been waived prior to the Closing.

          (r)  Exemption  from  Registration.  Assuming  (i) the accuracy of the
     information  provided by the  respective  Subscribers  in the  Subscription
     Documents  and the other  Offering  Documents  and (ii) that the  Placement
     Agent has complied in all material  respects  with the  provisions  of Rule
     502(c) of Regulation D promulgated  under the Securities Act, the offer and
     sale of the Units  pursuant to the terms of this  Agreement are exempt from
     the  registration  requirements  of the  Securities  Act and the  rules and
     regulations promulgated thereunder (the "Regulations").  The Company is not
     disqualified  from  the  exemption  under  Regulation  D by  virtue  of the
     disqualifications  contained in Rule 505(b)(2)(iii) or Rule 507 promulgated
     thereunder.

          (s) Registration  Rights.  Except with respect to holders of the Units
     and the Agent's Warrants and as stated in the Memorandum, no person has any
     right to cause the Company to effect the registration  under the Securities
     Act of any securities of the Company.

          (t) Brokers.  Neither the Company nor any of its officers,  directors,
     employees or  shareholders  has employed any broker or finder in connection
     with  the  transactions  contemplated  by this  Agreement  other  than  the
     Placement Agent.

          (u) Title to Units. When certificates representing the Reserved Shares
     shall have been duly  delivered to the  purchasers  and payment  shall have
     been made  therefor  (assuming  such  purchasers  are bona fide  purchasers
     within the meaning of the Uniform  Commercial Code), the several purchasers
     shall have  marketable  title to the Reserved  Shares free and clear of all
     liens,  encumbrances  and claims  whatsoever  (with the exception of claims
     arising  from or through the acts of the  purchasers  and except as arising
     from applicable  federal and state securities  laws), and the Company shall
     have paid all transfer taxes,  if any, in respect of the original  issuance
     thereof.

          (v) Right of First  Refusal.  Except for the right of first refusal to
     be granted to the Placement Agent, no person, firm or other business entity
     is a party to any


                                        7


<PAGE>
<PAGE>



     agreement, contract or understanding, written or oral, entitling such party
     to a right of first refusal with respect to the offer or sale of any equity
     or debt securities by the Company.

          (w) Solvency. The Company's assets currently exceed its liabilities.

         3. Representations and Warranties of the Placement Agent. The Placement
Agent represents and warrants to the Company as follows:

          (a) This Agreement has been duly authorized, executed and delivered by
     the  Placement  Agent and is a valid  and  binding  agreement  on its part,
     enforceable against the Placement Agent in accordance with its terms.

          (b) The Placement Agent is duly registered  pursuant to the provisions
     of the Exchange Act, as a broker-dealer and is a member in good standing of
     the National  Association of Securities Dealers,  Inc. ("NASD") and is duly
     registered as a broker-dealer in those states in which it is required to be
     so  registered  in order  to carry  out the  Offering  contemplated  by the
     Memorandum.

         4. Escrow; Closing; Placement and Fees.

         (a) Escrow  Account.  Funds received from the sale of the Units will be
deposited  by the  Placement  Agent with  Citibank,  N.A.,  as escrow agent (the
"Escrow  Agent"),  and held by the Escrow Agent in trust for the investors until
the  Placement  Agent is  required to deliver the funds to the Company or return
the funds to the investors upon  termination of the Offering or upon instruction
from the Company. All funds held in escrow will bear interest at 12% per annum.

         (b)  Closing.  Provided  the  minimum  number of Units  shall have been
subscribed  for in the Offering and funds  representing  the sale thereof  shall
have  cleared,  a closing  (the  "Closing")  shall take place at the  offices of
counsel to the Placement Agent,  Greenberg,  Traurig,  Hoffman,  Lipoff, Rosen &
Quentel,  Citicorp Center, 153 East 53rd Street,  35th Floor, New York, New York
10022,  within ten (10) days following the  Termination  Date (which date may be
accelerated  or  adjourned by  agreement  between the Company and the  Placement
Agent).  At the  Closing,  payment for the Units  issued and sold by the Company
shall be made  against  delivery of the Notes and the Warrants  comprising  such
Units.  In addition,  one or more  subsequent  closings (if  applicable)  may be
scheduled at the discretion of the Company and the Placement Agent.

         (c) Conditions to Placement Agent's Obligations. The obligations of the

and warranties of the Company  herein  contained as of the date hereof and as of
each  Closing  Date,  to the  performance  by  the  Company  of its  obligations
hereunder and to the following additional conditions:

the Placement Agent's reasonable opinion will in the immediate future materially
disrupt,  the  securities  markets;  (ii) a general  suspension of, or a general
limitation on prices for,  trading in securities on the New York Stock Exchange,
the American Stock Exchange or in the Nasdaq Stock Market; (iii) any outbreak of
major hostilities or other national or international  calamity; (iv) any banking
moratorium


                                       10

declared by a state or federal authority; (v) any moratorium declared in foreign
exchange  trading  by  major  international  banks or  other  persons;  (vi) any
material interruption in the mail service or other means of communication within
the  United  States;   (vii)  any  material  adverse  change  in  the  business,
properties,  assets, results of operations,  financial condition or prospects of
the Company;  or (viii) any change in the market for securities in general or in
political,  financial or economic  conditions  which,  in the Placement  Agent's
reasonable  judgment,  makes it  inadvisable to proceed with the Offering or the
sale and delivery of the Units.

         (g) Right of First Refusal.  During the period from the initial Closing
of this Offering  through  December 31, 2000, the Placement Agent shall have the
right of first  refusal  (the "Right of First  Refusal") to purchase for its own
account  or act as  underwriter  or  placement  agent for any and all  public or
private  offerings  of the  securities  of the Company,  or any  successor to or
subsidiary of the Company (collectively  referred to herein as the "Company") (a
"Subsequent Company Offering") and the Placement Agent shall also have the right
of first refusal to serve as the Company's investment banker with respect to any
potential acquisition, merger, divestiture,  strategic planning or other similar
activity  (a  "Business  Combination"),  but only if the  terms  offered  by the
Placement  Agent are comparable to those then being offered by other  investment
banking  firms to  similarly-situated  companies.  Accordingly,  if during  such
period the Company intends to make a Subsequent  Company Offering or the Company
intends to engage in any  Business  Combination,  the Company  shall  notify the
Placement Agent in writing of such intention of a Subsequent Company Offering or
Business  Combination.   The  Company  shall  thereafter  promptly  furnish  the
Placement  Agent with such  information  concerning the business,  condition and
prospects of the Company as the  Placement  Agent may  reasonably  request.  The
Placement Agent shall within twenty (20) business days after the receipt of such
notice of  intention,  provide the Company with the  proposed  terms by which it
would serve as underwriter,  placement agent or investment  banker,  as the case
may be, in the Subsequent Company Offering or Business Combination.  In no event
shall the Company  accept any  proposal  from any other  underwriter,  placement
agent or  investment  banker that is modified in any  material  respect from the
terms provided by the Placement Agent to the Company within six months after the
end of such 20 business days, and the Placement Agent's preferential right shall
be reinstated and the same  procedure with respect to such modified  proposal as
provided  above  shall be  adopted  with  respect  thereto.  The  failure by the
Placement  Agent  to  exercise  its  Right of First  Refusal  in any  particular
instance  shall  not  affect in any way such  right  with  respect  to any other
Subsequent Company Offering or Business Combination.

         5. Covenants of the Company.

         (a) Use of Proceeds.  The net proceeds of the Offering  will be used by
the Company as set forth in the Memorandum. The Company shall not use any of the
proceeds from the Offering to repay any indebtedness to any executive  officers,
directors  (other  than the  payment of  interest  to  Charles S.  Holmes and C.
Shelton  James  pursuant to the  Company's  subordinated  notes held by them) or
principal shareholders of the Company.

         (b) Expenses of Offering.  The Company  shall be  responsible  for, and
shall bear all  expenses  directly  incurred in  connection  with,  the proposed
Offering  including,  but not limited to, legal fees of its counsel  relating to
the costs of preparing the Offering  Documents and all  amendments,  supplements
and exhibits  thereto;  preparing and delivering all Placement Agent and selling
documents,  including,  but not limited to, this  Agreement  with the  Placement
Agent and the Blue Sky  memorandum;  the Notes,  the  Warrants  and the Reserved
Share certificates; Blue Sky fees and filing fees and the fees and disbursements
of counsel in connection with Blue Sky matters.  Such expenses shall not include
the cost of the Placement Agent's mailing,  telephone,  telegraph,  travel,  due
diligence  meetings  and other  similar  expenses and  reasonable  legal fees of
counsel  to the  Placement  Agent  (including  work on  certain  of the  matters
described above) which are covered by the accountable  expense allowance payable
by the Company to the Placement Agent.

         (c)  Termination  Fee.  In the event  that an  initial  Closing of this
Offering shall not be consummated, due to a breach by the Placement Agent of its
representations  contained in this Agreement,  prior to the later of (i) January
31, 1996 or (ii)  seventy (70) days after the receipt of the  Memorandum,  or as
extended for an additional thirty (30) days as specified in the Memorandum,  the
Company and the Placement  Agent shall be released from any and all  commitments
and obligations hereunder, except that the Company shall, nevertheless, promptly
upon demand reimburse the Placement Agent for its accountable  expenses incurred
in connection with this Offering (such as travel expenses and expenses  incurred
in due diligence investigations),  including, without limitation, the reasonable
fees and disbursements of the Placement  Agent's counsel for services  rendered.
If this Offering shall not be consummated  because the Company for any reason is
unable or unwilling to complete or otherwise determines not to proceed with this
Offering  (including the failure of the Company's  shareholders to authorize and
issue the  appropriate  number of shares of Common Stock and the possible change
in control resulting therefrom to effect the transactions  contemplated herein),
or if the Company  prevents the completion of this Offering prior to the initial
Closing because the Company  breaches any  representation,  covenant or warranty
contained herein or for any other reason, the Company shall promptly upon demand
reimburse  the  Placement  Agent  for  its  accountable   expenses  incurred  in
connection with this Offering (such as travel expenses and expenses  incurred in
due diligence  investigations),  including,  without limitation,  the reasonable
fees and disbursements of the Placement  Agent's counsel for services  rendered,
together  with a minimum of $250,000 to compensate  the Placement  Agent for the
efforts of its investment bankers and staff in connection with this Offering. In
no event,  however,  will the total  amount due to the  Placement  Agent  exceed
$400,000 in the aggregate.  If this Offering  shall not be  consummated  for any
reason  (other  than solely  because the  Placement  Agent  breached  any of its
representations  contained in this  Agreement) and the Company at any time prior
to December  31, 1996  engages in any merger or  business  combination  with any
other entity,  or sells control or all or substantially all of the assets of the
Company,  or engages in a financing other than through the Placement  Agent, the
Company  shall pay the  Placement  Agent  the  maximum  amount  set forth in the
preceding sentence.


                                       12

         (d)  Reservation of Capital  Stock.  The Company shall reserve and keep
available the maximum  number of its  authorized  but unissued  shares of Common
Stock  which are  issuable  upon  conversion  of the Notes and  exercise  of the
Warrants and the Agent's Warrants.

         (e)  Representation  on the Board of  Directors.  The investors in this
Offering  shall have the right,  for a period from the initial  Closing  through
December 31, 2001, to designate up to three (3) persons reasonably acceptable to
the Company to be members of the Board of Directors  of the  Company,  including
two (2) persons designated by Charles S. Holmes (including  himself) and one (1)
person  designated by C. Shelton  James.  The Company shall cause such number of
directors  currently serving on the Board of Directors to resign as directors on
or reasonably  promptly  after the initial  Closing of the Offering in order for
the investors'  designees to fill their vacancies.  The Board of Directors shall
consist of not more than seven (7)  directors,  except as otherwise  required by
the Restated Certificate of Incorporation of the Company. In addition, until the
earlier of December 31, 2001 or Winfield Capital Corp. ("Winfield") is no longer
a holder of any of the Company's securities, one (1) representative of Winfield,
as a  non-voting  "visitor,"  shall have the right to  receive  notice of and to
attend (at his or her own expense) all regular and special meetings of the Board
of Directors  (whether  the meeting is held in person or by means of  conference
telephone or similar communications  equipment),  subject to such representative
entering into a non-disclosure  agreement in form customary for such situations.
The Company  agrees that it shall hold "in person"  directors'  meetings no less
frequently  than  quarterly.  The  Company  agrees  to  indemnify  and  hold the
investors'  designees harmless against any and all claims,  actions,  awards and
judgments  arising solely out of the attendance and participation by them at any
such  meetings  described  herein,  in accordance  with the  Company's  Restated
Certificate  of  Incorporation  and  By-laws or as  otherwise  accorded to other
directors  of the  Company.  In the  event the  Company  maintains  a  liability
insurance policy affording  coverage for the acts of its officers and directors,
it agrees,  if possible,  to include the  investors'  designees as insured under
such policy.

         (f)  Notification.   The  Company  shall  notify  the  Placement  Agent
immediately,  and in writing,  (i) when any event shall have occurred during the
period  commencing  on the date  hereof  and  ending  on the  later of the final
Closing  or the  Termination  Date as a result of which the  Offering  Documents
would  include  any untrue  statement  of a  material  fact or omit to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading, and (ii) of the receipt of any notification with respect
to the modification,  rescission,  withdrawal or suspension of the qualification
or  registration  of the Units,  or of any exemption from such  registration  or
qualification,  in any  jurisdiction.  The Company  will use its best efforts to
prevent  the  issuance  of any  such  modification,  rescission,  withdrawal  or
suspension and, if any such modification,  rescission,  withdrawal or suspension
is issued and the Placement Agent so requests,  to obtain the lifting thereof as
promptly as possible.

         (g) Blue Sky.  The  Company  will use its best  efforts  to  qualify or
register the Units for offering and sale under,  or establish an exemption  from
such qualification

                                       13


<PAGE>
<PAGE>



or registration  under, the securities or "Blue Sky" laws of such  jurisdictions
as the Placement  Agent may  reasonably  request;  provided,  however,  that the
Company  will not be  obligated  to  qualify  as a dealer in  securities  in any
jurisdiction in which it is not so qualified;  and provided,  further,  that the
Company  shall not for any such  purpose be required to qualify  generally to do
business  as a  foreign  corporation  in any  jurisdiction  where,  but  for the
requirements  of  this  subsection  (g),  it  would  not be  obligated  to be so
qualified, to subject itself to taxation in any such jurisdiction, or to consent
to general service of process in any such  jurisdiction  (except pursuant to the
Uniform  Consent to Service of Process on Form U-1 or such other similar form as
may be required in any  jurisdiction).  The Company will not consummate any sale
of Units in any jurisdiction in which it is not so qualified or in any manner in
which such sale may not be lawfully made.

         (h) Form D Filing.  The  Company  shall file five copies of a Notice of
Sales of  Securities  on Form D with the  Commission no later than 15 days after
the first sale of the Units.  The Company shall file promptly such amendments to
such Notices on Form D as shall become  necessary and shall also comply with any
filing  requirement  imposed by the laws of any state or  jurisdiction  in which
offers and sales are made.  The Company shall  furnish the Placement  Agent with
copies of all such filings.

         (i) Press  Releases,  etc.  The  Company  shall not,  during the period
commencing  on the date hereof and ending on the later of the final  Closing and
the Termination  Date, issue any press release or other  communication,  or hold
any press  conference  with respect to the  Company,  its  financial  condition,
results of  operations,  business,  properties,  assets or  liabilities,  or the
Offering,  without  the prior  written  consent of the  Placement  Agent,  which
consent shall not be unreasonably withheld, or unless otherwise required by law.

         (j) Restrictions on Issuance of Securities.  Prior to the Closing Date,
the Company will not,  without the prior written consent of the Placement Agent,
issue additional shares of capital stock or grant any warrants, options or other
securities of the Company,  other than  pursuant to the exercise of  outstanding
stock options or to Charles S. Holmes or C. Shelton James.

         (k) Introduction  Fee. During the two-year period following the date of
the final  Closing,  the Company shall pay to the  Placement  Agent five percent
(5%) of the gross  amount of any  securities  purchased  of,  funds loaned to or
assets transferred to, the Company by any party introduced to the Company by the
Placement  Agent;  and, in the event that a party  introduced  by the  Placement
Agent  receives  securities  in  exchange  for any  services  rendered or assets
transferred  to the Company,  the Company will issue to the Placement  Agent the
same  securities in the amount of five percent (5%) of the securities  issued to
such  other  party.  Furthermore,  in the  event  any  party  introduced  by the
Placement Agent purchases the shares of capital stock of or all or substantially
all of the assets of or merges  with or into the  Company,  during the  two-year
period following the date of the final Closing, the Placement Agent will receive
five percent (5%) of the gross consideration to the Company or its shareholders.
This fee excludes  capital  raised from the conversion of the Notes and exercise
of


                                       14


<PAGE>
<PAGE>



the  Warrants  contemplated  herein.  In the event that the  Placement  Agent is
engaged by the Company  under the  conditions  of Section 4(h) hereof to perform
the same services as indicated in this Section 5(k), the Placement Agent will be
entitled  to the  greater of the two fees  called  for by Section  4(h) and this
Section 5(k).

         6. Covenants of the Placement Agent.

         (a) The  Placement  Agent  shall  offer  and  sell  the  Units  only to
"accredited investors," as that term is defined in Rule 501(a) promulgated under
the Securities Act.

         (b) The  Placement  Agent  agrees  not to engage in any  activities  in
connection  with the  offer of the Units in any state (i) in which the Units are
not  qualified  for sale or  exempt  from  qualification  under  the  applicable
securities or blue sky laws thereof;  (ii) in which the Placement  Agent may not
lawfully so engage or (iii) in which it is not a registered broker-dealer.

         (c) The Placement Agent will use its best efforts to offer the Units in
compliance with the requirements of Regulation D.

         7. Indemnification.

         (a) The Company  agrees to indemnify  and hold  harmless the  Placement
Agent and its officers,  directors,  employees and agents,  and each person,  if
any, who controls the Placement Agent as follows:

          (i) against  any and all loss,  liability,  claim,  damage and expense
     whatsoever,  and to reimburse the Placement Agent for reasonable legal fees
     and related  expenses as incurred,  arising out of any untrue  statement or
     alleged  untrue  statement  of a material  fact  contained  in the Offering
     Documents or the omission or alleged omission  therefrom of a material fact
     necessary  in  order  to make  the  statements  therein,  in  light  of the
     circumstances under which they were made, not misleading;

          (ii) against any and all loss,  liability,  claim,  damage and expense
     whatsoever,  and to reimburse the Placement Agent for reasonable legal fees
     and related  expenses as incurred,  to the extent of the  aggregate  amount
     paid in settlement of any litigation, commenced or threatened, or any claim
     whatsoever  based upon any such  untrue  statement  or omission or any such
     alleged untrue  statement or omission,  if such settlement is effected with
     the written  consent of the Company (which consent will not be unreasonably
     withheld or delayed); and

          (iii)   against   any  and  all   expense   whatsoever   incurred   in
     investigating,  preparing or defending against any litigation, commenced or
     threatened,  or any claim whatsoever,  and to reimburse the Placement Agent
     and its officers, directors, employees


                                       15


<PAGE>
<PAGE>



     and agents,  and each person, if any, who controls the Placement Agent, for
     reasonable  legal and  related  expenses as  incurred,  based upon any such
     untrue  statement or  omission,  or any such  alleged  untrue  statement or
     omission,  to the extent that any such expense is not paid under clause (i)
     or (ii)  above;  provided,  however,  that  the  foregoing  indemnification
     provided in  paragraphs  (i), (ii) and (iii) of this Section 7(a) shall not
     apply to any loss,  liability,  claim, damage or expense arising out of any
     information  with  respect  to the  Placement  Agent or Lead  Investor  (as
     referred to in the  Memorandum)  contained  in the  Offering  Documents  in
     reliance upon written information furnished by the Placement Agent.

         (b) The Company  agrees to indemnify  and hold  harmless the  Placement
Agent and its officers,  directors,  employees and agents,  and each person,  if
any, who  controls  the  Placement  Agent,  to the same extent as the  foregoing
indemnity,  against  any and all loss,  liability,  claim,  damage  and  expense
whatsoever directly arising out of the exercise by any person of any right under
the  Securities  Act or the Exchange Act, or the  securities or Blue Sky laws of
any state on account of a breach of any of the  representations,  warranties  or
agreements set forth in Section 2 hereof.

         (c) The  Placement  Agent  agrees to  indemnify  and hold  harmless the
Company,  each  director,  officer,  employee or agent of the Company,  and each
other person,  if any, who controls the Company within the meaning of Section 15
of the Securities Act or Section 20(a) of the Exchange Act to the same extent as
the foregoing indemnity from the Company to the Placement Agent in Sections 7(a)
and 7(b) above,  but only with respect to statements or omissions,  if any, made
in  the  Memorandum,   or  any  amendment  or  supplement  thereto,  or  in  any
application,  in  reliance  upon  and in  conformity  with  written  information
furnished  to the  Company as stated in this  Section  7(c) with  respect to the
Placement Agent  expressly for inclusion in the Memorandum,  or any amendment or
supplement  thereto,  or in any  application,  as the  case  may  be;  provided,
however,  that the obligation of the Placement Agent to provide  indemnity under
the  provisions  of this  Section  7(c) shall be  limited  to the  amount  which
represents the product of the number of Units sold by the Placement Agent in the
Offering  and the  purchase  price per Unit set  forth on the cover  page of the
Memorandum.  For all purposes of this Agreement,  the statements set forth under
the   headings   "Investor   Suitability    Standards"   and   "Terms   of   the
Offering--Placement Agent's Compensation" and "--Subscription Procedures" in the
Memorandum  constitute the only information furnished in writing by or on behalf
of the  Placement  Agent  expressly  for  inclusion  in the  Memorandum,  or any
amendment or supplement thereto,  or in any application,  as the case may be. If
any  action  shall be  brought  against  the  Company  or any  other  person  so
indemnified based on the Memorandum,  or any amendment or supplement thereto, or
in any application,  and in respect of which indemnity may be sought against the
Placement  Agent pursuant to this Section 7(c),  the Placement  Agent shall have
the rights and  duties  given to the  Company,  and the  Company  and each other
person so indemnified  shall have the rights and duties given to the indemnified
parties, by the provisions of Sections 7(a) and 7(b) above.

         (d)  Promptly  after  receipt by a person  entitled to  indemnification
pursuant to the foregoing  subsection (a), (b) or (c) (an  "indemnified  party")
under this Section



                                       16


<PAGE>
<PAGE>



7 of notice of the commencement of any action,  the indemnified party will, if a
claim in respect thereof is to be made against the other party (an "indemnifying
party")  under this  Section,  notify in writing the  indemnifying  party of the
commencement  thereof; but the omission so to notify the indemnifying party will
not relieve it from any  liability  which it may have to the  indemnified  party
otherwise than under this Section 7. In case any such action is brought  against
an indemnified party, and it notifies the indemnifying party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  to assume  the  defense  thereof,  subject to the  provisions  herein
stated, with counsel reasonably satisfactory to the indemnified party, and after
notice from the indemnifying  party to the indemnified  party of its election so
to assume the defense thereof,  the indemnifying party will not be liable to the
indemnified  party  under  this  Section  7 for  any  legal  or  other  expenses
subsequently  incurred by the  indemnified  party in connection with the defense
thereof other than reasonable  costs of  investigation.  The  indemnified  party
shall  have the right to  employ  separate  counsel  in any such  action  and to
participate  in the defense  thereof,  but the fees and expenses of such counsel
shall not be at the expense of the indemnifying  party if the indemnifying party
has assumed the defense of the action with counsel  reasonably  satisfactory  to
the indemnified party; provided that the fees and expenses of such counsel shall
be at the  expense  of the  indemnifying  party  if (i) the  employment  of such
counsel has been specifically authorized in writing by the indemnifying party or
(ii) the named  parties to any such action  (including  any  impleaded  parties)
include  both the  indemnified  party or parties  and the  Company  and,  in the
judgment of the indemnified  party, it is advisable for the indemnified party or
parties to be  represented by separate  counsel (in which case the  indemnifying
party shall not have the right to assume the defense of such action on behalf of
the  indemnified  party or  parties,  it  being  understood,  however,  that the
indemnifying party shall not, in connection with any one such action or separate
but substantially  similar or related actions in the same  jurisdiction  arising
out of the  same  general  allegations  or  circumstances,  be  liable  for  the
reasonable fees and expenses of more than one separate firm of attorneys for the
indemnified  party  or  parties).   No  settlement  of  any  action  against  an
indemnified  party shall be made without the consent of the  indemnified  party,
which shall not be  unreasonably  withheld in light of all factors of importance
to the indemnified party.

         8. Contribution.

         (a)  To  provide  for  just  and  equitable  contribution,  if  (i)  an
indemnified party makes a claim for indemnification pursuant to Section 7 but it
is found in a final judicial determination,  not subject to further appeal, that
such  indemnification  may  not be  enforced  in such  case,  even  though  this
Agreement  expressly  provides  for  indemnification  in such case,  or (ii) any
indemnified or indemnifying  party seeks  contribution under the Securities Act,
the Exchange Act, or otherwise,  then the indemnifying party (including for this
purpose any contribution made by or on behalf of any officer, director, employee
or  agent  for  the  indemnifying  party,  or  any  controlling  person  of  the
indemnifying  party),  on the one hand, and the indemnified party (including for
this purpose any contribution by or on behalf of an indemnified  party),  on the
other hand, shall contribute to the losses,  liabilities,  claims,  damages, and
expenses  whatsoever to which any of them may be subject, in such proportions as
are


                                       17


<PAGE>
<PAGE>



appropriate to reflect the relative benefits received by the indemnifying party,
on the one  hand,  and the  indemnified  party,  on the  other  hand;  provided,
however,  that if  applicable  law does not permit such  allocation,  then other
relevant equitable considerations such as the relative fault of the indemnifying
party and the  indemnified  party in connection with the facts which resulted in
such  losses,   liabilities,   claims,  damages,  and  expenses  shall  also  be
considered.  In no case shall the indemnified party be responsible for a portion
of the  contribution  obligation  in excess of the  compensation  received by it
pursuant to Section 4 hereof. No person guilty of a fraudulent misrepresentation
shall be  entitled  to  contribution  from any  person who is not guilty of such
fraudulent  misrepresentation.  For purposes of this Section 8, each person,  if
any, who controls the indemnified  party within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act and each officer,  director,
stockholder,  employee and agent of the indemnified  party,  shall have the same
rights to contribution as the indemnified  party,  and each person,  if any, who
controls  the  indemnifying  party  within  the  meaning  of  Section  15 of the
Securities Act or Section 20(a) of the Exchange Act and each officer,  director,
employee  and agent of the  indemnifying  party,  shall have the same  rights to
contribution as the indemnifying  party,  subject in each case to the provisions
of this Section 8.  Anything in this Section 8 to the contrary  notwithstanding,
no party shall be liable for contribution  with respect to the settlement of any
claim or action effected without its written consent. This Section 8 is intended
to supersede any right to  contribution  under the Securities  Act, the Exchange
Act, or otherwise.

         9. Miscellaneous.

         (a) Survival.  Any  termination  of the Offering  without  consummation
thereof shall be without  obligation on the part of any party except the payment
of certain fees and  expenses  pursuant to Sections  5(b) and 5(c)  hereof,  the
indemnification  provisions  provided  in Section 7 hereof and the  contribution
provided in Section 8 hereof shall survive any termination and that specifically
the provisions  contained in Section 7 regarding  indemnification  and Section 8
regarding contribution shall survive the Closing for a period of five years.

         (b) Representations,  Warranties and Covenants to Survive Delivery. The
respective representations,  warranties, indemnities,  agreements, covenants and
other statements of the Company as of the date hereof shall survive execution of
this Agreement and delivery of the Units and the termination of this Agreement.

         (c) No Other Beneficiaries. This Agreement is intended for the sole and
exclusive  benefit of the parties  hereto and their  respective  successors  and
controlling  persons,  and no other person,  firm or corporation  shall have any
third-party  beneficiary  or other rights  hereunder.  This Agreement may not be
assigned without the prior written consent of the parties hereto.

         (d) Governing Law. This Agreement shall be governed by and construed in
accordance  with the law of the State of New York without  regard to conflict of
law provisions.


                                       18

         (e) Counterparts. This Agreement may be signed in counterparts with the
same effect as if both parties had signed one and the same instrument.

         (f) Notices. Any communications  specifically  required hereunder to be

                  (BW)   (NAI-TECHNOLOGIES)(NATL)   NAI  Technologies  announces
completion of private  placement of convertible notes and warrants and bank debt
extension.

                  LONGMONT,    Colo.--(BUSINESS    WIRE)--Feb.   15,   1996--NAI
Technologies,  Inc.  (NATL/NASDAQ)  today  announced the completion of a private
placement  of   approximately   $8,000,000  of  the  company's  12%  Convertible
Subordinated  Promissory Notes due 2001 and Warrants to purchase an aggregate of
4,000,000  shares  of the  company's  Common  Stock  with  a  group  of  private
investors.

                  The company also  announced  that it has executed an amendment
to its credit  agreement  with its bank lenders  which  amended and extended the
payment provisions and reset certain financial covenants on more favorable terms
for the  company.  The credit  agreement,  as revised,  provides  for  principal
payments of $500,000 on each of March 31,  1996,  June 30, 1996,  September  30,
1996 and  December  31,  1996  and  $750,000  on the  last  day of each  quarter
thereafter,  commencing  on March 31,  1997 and  ending on  December  31,  1998,
together with accrued and unpaid interest  through the applicable  payment date.
The remaining  outstanding  principal amount of $7,975,000 is due and payable on
January 15,  1999.  The  interest  rate,  bank fees,  collateral,  non-financial
covenants  and events of default have not been  modified by the amendment to the
credit agreement.

                  The Notes are  convertible by the holder into shares of Common
Stock at a conversion  price equal to $2.00 per share,  subject to adjustment in
certain events.  Interest on the Notes is payable quarterly commencing April 15,
1996.  The Notes mature on January 15, 2001 and are subject to prepayment at any
time after the third  anniversary  of the date of  issuance at the option of the
company without premium or penalty.  The Notes are unsecured  obligations of the
company  subordinate  in right of  payment  to all  senior  indebtedness  of the
company.  The Warrants  entitle the holders thereof to purchase shares of Common
Stock at any time and from time to time on or before  February 15,  2002,  at an
exercise  price equal to $2.50 per share of Common Stock,  subject to adjustment
in certain events. The Warrants are detachable and separately transferable.

                  The issuance of the  securities  was approved by the company's
shareholders at a Special  Meeting of Shareholders  held in Longmont on February
1,  1996.  If all  of the  Notes  are  converted  and  all of the  Warrants  are
exercised,  the  company  will  have  received  gross  proceeds  of  $18,000,000
(approximately $16,860,000 net) in exchange for the sale of

approximately  49.6% of the  shares of Common  Stock on a  fully-diluted  basis,
based on shares currently outstanding.

                  Included in the group of investors  were Charles S. Holmes and
C. Shelton James, both of whom are directors of the company.

                  The net proceeds  realized by the company from the sale of the
securities, after the payment of fees and expenses associated with the offering,
including a placement  fee, are estimated to be  approximately  $6,860,000.  The
company  intends  to use the net  proceeds  to pay  amounts  past due to vendors
primarily  for raw  materials  and  components  as well as for  other  corporate
purposes.
