                    SUBORDINATED CONVERTIBLE PROMISSORY NOTE

                         MADE BY A4S TECHNOLOGIES, INC.

                         ADDITIONAL TERMS AND CONDITIONS

     These Additional Terms and Conditions are attached to and shall be made a
part of the Convertible Promissory Note of A4S TECHNOLOGIES, INC. (the
"Company") payable to Cambridge Holdings, Ltd. ("Holder") dated October 2, 2003
(the "Note"), as if incorporated therein:

     1. This Note is one of a series of notes issued under the Subordinated
Convertible Note Purchase Agreement among the Company, Holder and other
purchasers listed in Annex A thereof (the "Purchase Agreement). Each Holder of
this Note will be deemed by its acceptance hereof to have made the
representations set forth in Article 6 of the Purchase Agreement.

     2. Holder shall have the right at Holder's option, at any time prior to
payment of the Note, to convert any or all of the principal amount of this Note
into such number of fully paid and non-assessable shares of the common stock
(the "Common Stock") of the Company as shall be provided herein. Holder may
exercise the conversion right provided in this Section 1 by giving written
notice (the "Conversion Notice") to the Company of the exercise of such right
and stating the address to which the certificates evidencing the Common Stock
shall be delivered. The Conversion Notice shall be accompanied by this Note.
Except as provided below in this Section 1, the Company will issue one share of
Common Stock for each $1.00 of then outstanding principal balance of this Note
upon conversion of the Note (the "Conversion Price"). Conversion shall be deemed
to have been effected on the date the Conversion Notice is given; provided,
however, the conversion privilege of this Note may not be exercised by, and the
Common Stock shall not be issued to, Holder if such conversion would be
unlawful. As a condition to conversion, the Company may require Holder to sign a
representation letter confirming compliance with applicable federal and state
securities laws and other applicable laws, and the Company shall be entitled to
receive satisfactory assurance that issuance of the Common Stock will not
violate law. Promptly after receipt of the Conversion Notice and confirmation of
compliance with law, the Company shall issue a stock certificate of the Company
representing the number of shares of Common Stock to which Holder is entitled
and all accrued interest unpaid on the principal amount of the Note which is the
subject of the Conversion Note up to and including the date of the Conversion
Notice shall be paid to Holder on the Maturity Date unless Holder has indicated
that he also wishes to convert the accrued interest into shares of Common Stock
in which event the stock certificate shall include the number of shares issued
in conversion of the accrued interest, calculated on the same terms and in the
same manner as the principal converted.

     3. All of the principal amount of this Note shall automatically be
converted into Common Stock of the Company at the then effective Conversion
Price immediately upon the closing of the sale of the Company's Common Stock in
a publicly offering registered under the Securities Act of 1933, as amended (the
"Securities Act") other than a registration relating solely to a transaction
under Rule 145 under such Act (or any successor thereto) or to a employee
benefit plan of the Company, at a public offering price (prior to any
underwriters' discounts and expenses) having (a) aggregate proceeds to the
Company of at least $2,500,000 and (b) an offering price per share of not less
than $3 as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to the Common Stock).

<PAGE>
     4. If the Common Stock issuable upon conversion of this Note shall be
changed into the same or different number of shares of any other class or
classes of stock, whether by capital reorganization, reclassification or
otherwise, appropriate adjustment shall be made to the Conversion Price. Similar
adjustments shall be made in the event of any reorganization, merger or
consolidation.

     5. If the Company shall issue any additional shares of Common Stock without
consideration or for a consideration per share less than $1.00 per share (as
appropriately adjusted pursuant to Section 4 above), on such date, the
Conversion Price in effect immediately prior to each such issuance shall
forthwith be adjusted to a price equal to a price determined by multiplying the
Conversion Price by a fraction, the numerator of which shall be the sum of (w)
the number of shares of Common Stock outstanding immediately prior to such
issuance and (x) the number of shares of Common Stock that the aggregate
consideration received by the Company for such issuance would purchase at $1.00
per share (as appropriately adjusted pursuant to Section 4 above); and the
denominator of which shall be the sum of (y) the number of shares of Common
Stock outstanding immediately prior to such issuance and (z) the number of
additional shares of such Common Stock. For purposes of this Section 5, if any
securities are issued by the Company which are convertible into Common Stock or
which may be exercised to acquire Common Stock, then the aggregate maximum
number of shares of Common Stock deliverable upon conversion or exercise of the
securities assuming the satisfaction of any conditions to convertibility or
exercisability, shall be deemed to have been issued at the time such securities
were issued. Upon the termination or expiration of the convertibility or
exercisability of any such securities, the Exercise Price, to the extent in any
way affected by or computed using such securities, shall be recomputed to
reflect the issuance of only the number of shares of Common Stock actually
issued upon the conversion or exercise of such securities.

     6. If the Company's revenue per share for calendar year 2004 is below $2.50
per share, the Conversion Price in effect immediately prior to the Measurement
Date (as defined below) shall forthwith be adjusted to a price equal to a price
determined by multiplying the Conversion Price by a fraction, the numerator of
which shall be the Company's revenue per share for calendar year 2004 and the
denominator of which shall be $2.50 (as appropriately adjusted pursuant to
Section 4 above). Provided, however, that the Conversion Price may not be
reduced by more than 50% below the Conversion Price in effect immediately prior
to the Measurement Date. For purposes of this Section 6, revenue per share shall
be determined in accordance with generally accepted accounting principles
consistently applied by the Company after consultation with a nationally
recognized firm of independent certified public accountants engaged by the
Company. The number of shares shall be calculated on a fully-diluted basis
assuming the conversion, exchange, exercise or purchase of all outstanding
convertible or exchangeable securities, or rights, options or warrants or
similar instruments to purchase Common Stock. The revenue per share shall be
determined as soon as reasonably practicable after December 31, 2004, but in no
event later than January 31, 2005 (the "Measurement Date").

<PAGE>
     7. Payment of the principal of and interest of this Note is subordinated in
right of payment of the principal of and interest on the "Senior Indebtedness"
of the Company. Senior Indebtedness shall mean any present and future debts and
obligations of the Company, due or to become due, owed by the Company to a
senior secured lender. Any Senior Indebtedness, other than debt incurred with an
institutional lender that is secured by the Company's inventory and accounts
receivable, will be subject to the approval of the Required Purchasers (as said
term is defined in the Purchase Agreement), which approval shall not be
unreasonably withheld.
