                              MASTER NOTE AGREEMENT

July 1, 1996


BarOn Technologies, Ltd.
Gutwirth Science Park
Technion City
Haifa 32000 Israel

Gentlemen:

     We have agreed to make available a line of credit in the amount of
$2,000,000 (the "line of credit" or the "line") under which you may request, and
we may grant, loans or other extensions of credit to you from time to time for
business purposes ("Loan(s)" or "Extension(s) of Credit"). This Agreement sets
forth the procedures, terms and conditions for borrowing under the line. As used
in this Agreement, the terms we, us, our and EAI mean EA Industries, Inc., a New
Jersey corporation and the terms you and your mean BarOn Technologies, Ltd. an
Israeli corporation. This letter does not constitute a commitment to lend or to
extend credit but instead describes the procedures for application for advances
under the line. It is understood and agreed that Loans and Extensions of Credit
granted under the line will be governed by the following:

     1. Requests for Loans. A person duly authorized under Paragraph 2 may
request Loans or Extensions of Credit by telephone or letter. We will consider
the request and will notify you within three (3) weeks of the request as to
whether it will make a loan for all, part or none of the amount requested. Such
decision shall be made at our sole discretion for any reason. If we elect to
make a Loan or Extension of Credit, then we will wire such sum upon your written
instructions. Upon your request we will forward to you a written advice or
statement of each Loan or Extension of Credit which will specify the manner of
disbursement, the rate or rates of interest payable on the Loan or Extension of
Credit if different from the rate set forth in Paragraph 5 and such other terms
as may have been agreed to.

     2. Resolutions Authorizing Loans. Any and all documents required to be
executed in conjunction with Loans or Extensions of Credit may be signed by any
of the officers or other persons duly authorized by your borrowing resolutions
as in effect from time to time, provided that a copy of such resolutions is
certified by the Secretary of your corporation and delivered to us. We shall
incur no liability to you or any other person in acting upon any request for a
Loan or 


                                       1


Extension of Credit which we believe in good faith to have been made by a person
duly authorized to borrow on your behalf as set forth in your borrowing
resolutions.

     3. EAI Records Conclusive. The amount and terms of Loans or Extensions of
Credit and the rate or rates of interest payable on them and your repayments and
those made on your behalf shall be established and evidenced by our records
which shall be conclusively deemed to be correct in the absence of manifest
error.

     4. Amount of Line and Payment of Loans. As long as the line of credit
remains outstanding, you may borrow, repay and reborrow up to the maximum
specified in this Agreement. The line of credit will terminate on July 1, 1998
or upon the occurrence of any event of default as described in Section 13, if
earlier, the amount available under the line shall initially be $2,000,000, and
shall be reduced dollar for dollar by the proceeds to the Company from any sale
of equity, issuance of Debentures or additional borrowings from third parties.
Upon the payment of any Loan or Extension of Credit as provided above, accrued
and unpaid interest on the amount repaid shall be simultaneously paid unless we
agree otherwise. All unpaid principal and any remaining unpaid but accrued
interest shall be due and payable upon the first to occur of (i) the end of any
calendar quarter during the term of this Agreement during which the cash flows
from sales of the Borrower and its subsidiaries exceeds the sum of (x) net cash
used by operations, and (y) the outstanding principal and accrued interest on
the line at the end of such quarter, (ii) June 1, 2000, (iii) sale of equity,
issuance of debentures or additional borrowings from third parties in one or a
series of transactions, with aggregate proceeds to the Borrower exceeding such
unpaid principal and interest by at least $500,000, unless repayment of such
sums to the Lender is prohibited at the request of such investor(s) or
lender(s), or (iv) the closing of an initial public offering of equity of (or
equivalent right to or in) the Borrower.

     5. Interest. Unless otherwise agreed in writing, interest on all
outstanding Loans and Extensions of Credit shall be computed at a rate per annum
equal to one and one-half percent (1 1/2%) in excess of the rate established and
announced publicly by I.B.J. Schroder Bank & Trust Company as the base
commercial lending rate (the "Base Rate"). Said per annum rate shall change each
time the Base Rate shall change effective as of the date of the change. Each
overdue payment of principal on any Loan and any Extension of Credit and, to the
extent permitted by law, each overdue payment of interest shall bear interest,
payable on demand, for each day until paid at a rate per annum equal to the
lesser of (i) 10% in excess of the Base Rate, or (ii) the maximum interest rate
allowed by law. Interest on all Loans and Extensions of Credit shall be computed
on the basis of a year of 360 days for each day of the year actually elapsed.

     During each year of the term of this Agreement, the Borrower shall have the
option, exercisable by delivery of written notice to Lender at least ten (10)
days before the date interest 


                                       2


would otherwise be due and payable, to defer any and all quarterly payments of
interest until the succeeding anniversary date of this Agreement. Deferred
interest shall accrue additional interest of two and one half percent (2 1/2%)
in excess of the Base Rate. Deferred interest shall be due and payable upon such
anniversary date.

     The Borrower shall have the option, during the first year of this Agreement
to make any deferred interest payments to Lender on the first anniversary date
in ordinary shares, par value N.I.S. 0.01 per share of the Borrower ("Common
Stock"). This option may be exercised by delivery of written notice to the
Lender at least five days before such payment date. If the option is elected,
the Borrower shall issue and dispatch to the Lender one or more Certificates for
the aggregate number of whole shares of Common Stock determined by dividing
$4.00, U.S. Dollars, into the total amount of lawful money of the United States
of America which the Holder would receive if the aggregate amount of interest on
this Note which is being paid in shares of Common Stock were being paid in such
lawful money. No fractional shares will be issued in payment of interest on this
Note. In lieu thereof, the Borrower may issue a number of shares of Common Stock
which reflects a rounding up to the next whole number or may pay lawful money of
the United States of America.

     The Lender shall have the option to have interest payments made to it in
shares of Common Stock. This option may be exercised on any one or more of the
dates interest is payable under this Agreement by delivery of written notice to
the Borrower at least five days before such payment date. If the option is
elected, the Borrower shall issue and dispatch to the Lender one or more
Certificates for the aggregate number of whole shares of Common Stock determined
by dividing $4.00, U.S. Dollars into the total amount of lawful money of the
United States of America which the Holder would receive if the aggregate amount
of interest on this Note which is being paid in shares of Common Stock were
being paid in such lawful money. No fractional shares will be issued in payment
of interest on this Note. In lieu thereof, the Borrower may issue a number of
shares of Common Stock which reflects a rounding up to the next whole number or
may pay lawful money of the United States of America.

     6. Payment of Costs. In addition to the principal and interest payments
specified in paragraphs 4 and 5, you agree to pay, upon demand, all costs and
expenses (including reasonable attorneys' fees and legal expenses) we incur in
enforcing this Agreement.

     14. Warrant/Antidilution. The Lender currently holds 3,570,514 shares of
stock of the Borrower, which has agreed to issue additional shares to the Lender
under certain circumstances, as described in this Section 14.

          (a) Definition of "Shares". As used herein, "Shares" shall mean the
Company's ordinary shares, par value N.I.S. 0.01 per share (the "Common Stock")
which is the class of capital stock currently owned by the Lender.

          (b) Issuance of Additional Shares of Capital Stock. Additional Shares
of Capital Stock shall mean all shares of Capital Stock issued by the Company,
except Options to purchase shares of Common Stock granted by the Company after
the date hereof as an incentive for performance to officers, directors,
employees and consultants providing services to the Company and the shares of
Common Stock issuable upon the exercise of such options provided that the option
exercise price for such options is at least $4.00 U.S. Dollars per share, or a
lower exercise price was approved in writing by the Lender or a representative
of the Lender serving as a director of the Company. Capital Stock shall mean the
Common Stock and any other stock of any class, or series within a class, which
has the right to participate in the distribution of earnings or assets of the
Company without limit as to amount or percentage.

          If the Company at any time while the Lender is a shareholder shall
issue any Additional Shares of Capital Stock at a price per share less, or for
other consideration lower than $4.00 per share, U.S. Dollars, (the "Initial
Price") or without consideration, then upon such issuance shall be issued
Additional Shares of Common Stock determined by (x) multiplying the number of
shares held by the Lender immediately prior to such event by a fraction:

               (i) the numerator of which shall be the number of shares of
Capital Stock outstanding immediately prior to the issuance of such Additional
Shares of Capital Stock plus the number of such Additional Shares of Capital
Stock so issued; and

               (ii) the denominator of which shall be the number of shares of
Capital Stock outstanding immediately prior to the issuance of such Additional
Shares of Capital Stock plus the number of shares of Capital Stock which the
aggregate consideration for the total number of such Additional Shares of
Capital Stock so issued would purchase at $4.00 U.S. Dollars per share; and

(y) subtracting from that result the number of shares held by Lender immediately
prior to such event.


                                       10


          (c) Issuance of Warrants, Options or Other Rights. If the Company at
any time while the Lender is a shareholder shall issue any warrants, options or
other rights to subscribe for or purchase any Additional Shares of Capital Stock
and the price per share for which Additional Shares of Capital Stock may at any
time thereafter be issuable pursuant to such warrants, options or other rights
shall be less than the Initial Price then upon such issuance the Lender shall be
issued additional shares as provided in Subsection 14(b) hereof on the basis
that:

               (i) the maximum number of Additional Shares of Capital Stock
issuable pursuant to all such warrants, options or other rights shall be deemed
to have been issued as of the date of actual issuance of such warrants, options
or other rights, and

               (ii) the aggregate consideration for such maximum number of
Additional Shares of Capital Stock issuable pursuant to such warrants, options
or other rights, shall be deemed to be the consideration received by the Company
for the issuance of such warrants, options or other rights plus the minimum
consideration to be received by the Company for the issuance of Additional
Shares of Capital Stock pursuant to such warrants, options, or other rights.

          (d) Issuance of Convertible Securities. If the company at any time
while this Warrant remains outstanding and unexpired shall issue any securities
convertible into Capital Stock and the consideration per share for which
Additional Shares of Capital Stock may at any time thereafter be issuable
pursuant to the terms of such convertible securities shall be less than the
Initial Price then upon such issuance the Lender shall be issued additional
shares as provided in Subsection 14(b) hereof on the basis that:

               (i) the maximum number of Additional Shares of Capital Stock
necessary to effect the conversion or exchange of all such convertible
securities shall be deemed to have been issued as of the date of issuance of
such convertible securities, and

               (ii) the aggregate consideration for such maximum number of
Additional Shares of Capital Stock shall be deemed to be the consideration
received by the Company for the issuance of such convertible securities plus the
minimum consideration to be received by the Company for the issuance of such
Additional Shares of Capital Stock pursuant to the terms of such convertible
securities.

          No issuance of additional shares shall be made under this Subsection
14(d) upon the issuance of any convertible securities which are issued pursuant
to the exercise of any warrants, options or other subscription or purchase
rights therefor, if any such adjustment shall previously have been made upon the
issuance of such warrants, options or other rights pursuant to Subsection 14(c)
hereof.


                                       11


          (e) Other Provisions Applicable to Adjustments Under this Section. The
following provisions will be applicable to the making of adjustments provided in
this Section 14:

               (i) Computation of Consideration. To the extent that any
Additional Shares of Capital Stock or any convertible securities or any
warrants, options or other rights to subscribe for or purchase any Additional
Shares of Capital Stock or any convertible securities shall be issued for a cash
consideration, the consideration received by the Company therefor shall be
deemed to be the amount of the cash received by the Company therefor, or, if
such Additional Shares of Capital Stock or convertible securities are offered by
the Company for subscription, the subscription price, or, if such Additional
Shares of Capital Stock or convertible securities are sold to underwriters or
dealers for public offering without a subscription offering, the initial public
offering price, in any such case excluding any amounts paid or incurred by the
Company for and in the underwriting of, or otherwise in connection with the
issue thereof. To the extent that such issuance shall be for a consideration
other than cash, then, the amount of such consideration shall be deemed to be
the fair value of such consideration at the time of such issuance as determined
in good faith by the Company's Board of Directors. The consideration for any
Additional Shares of Capital Stock issuable pursuant to any warrants, options or
other rights to subscribe for or purchase the same shall be the consideration
received by the Company for issuing such warrants, options or other rights, plus
the minimum additional consideration payable to the Company upon the exercise of
such warrants, options or other rights. The consideration for any Additional
Shares of Capital Stock issuable pursuant to the terms of any convertible
securities shall be the consideration paid or payable to the Company in respect
of the subscription for or purchase of such convertible securities, plus the
minimum additional consideration, if any, payable to the Company upon the
exercise of the right of conversion or exchange in such convertible securities.
In case of the issuance at any time of any Additional Shares of Common Stock or
convertible securities in payment or satisfaction of any dividend upon any class
of stock preferred as to dividends in a fixed amount, the Company shall be
deemed to have received for such Additional Shares of Capital Stock or
convertible securities a consideration equal to the amount of such dividend so
paid or satisfied.

               (ii) Treasury Shares. The number of shares of Common Stock at any
time outstanding shall not include any shares thereof then directly or
indirectly owned or held by or for the account of the Company or any subsidiary
or affiliate.

          (e) Ownership Limit. The Borrower has issued on the date hereof a
Warrant (the "Warrant") to EAI entitling EAI to purchase shares of stock of the
Borrower. EAI has agreed that it will not at anytime own in excess of 49% of all
of the issued and outstanding ordinary 


                                       12


shares of the Borrower if the issuance of shares pursuant to the antidilution
provisions of this Section 14 would result in EAI exceeding this limit such
issuance shall be delayed to the extent necessary to keep EAI below such limit.
The issuance shall be made at the earliest date possible in light of such
agreement.

     15. Acceleration. Whenever you are in default, unless we elect otherwise,
the entire unpaid amount of such of the Liabilities as are not then due and
payable shall become due and payable without notice to or demand on any Obligor.
You waive all right to stay of execution and exemption of property in' any
action to enforce the Liabilities.

     16. Personal Liability. No shareholder, officer, director or employee of
the Borrower shall have any personal liability or obligation to make principal

or for any other obligations of Borrower hereunder.

     17. Governing Law. This Agreement, the Master Note, and any other notes
issued under this Agreement shall be construed in accordance with and governed
by the internal laws of the State of New Jersey.

     18. Withholding. The Borrower shall have the right to deduct from any
interest payment made to the Lender any taxes that it is required by law to
withhold.

     19. Miscellaneous. Any failure by us to exercise any right under this
Agreement shall not be construed as a waiver of its right to exercise the same
or any other right at any other time. If more than one person signs this
Agreement as borrower, then such persons shall be jointly and severally liable
under this Agreement. The parties intend this Agreement to be a sealed
instrument and to be legally bound by it.
