                           API ELECTRONICS GROUP INC.

            THIS CERTIFIES that, for value received, Syrah Invest Corp. (the
"Holder"), is entitled, upon the terms and subject to the limitations on
exercise and the conditions hereinafter set forth, at any time on or after June

Capitalized terms used and not otherwise defined herein shall have the meanings
set forth in that certain Subscription Agreement (the "Purchase Agreement"),
dated June *, 2002, between the Company and the Holder.

<PAGE>

                                        2

1.      Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney, upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

2.      Authorization of Shares. The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights represented by this Warrant,
be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such issue).

3.      Exercise of Warrant.

        (a)    Except as provided in Section 4 herein, exercise of the purchase
rights represented by this Warrant may be made at any time or times on or after
the Initial Exercise Date and on or before the Termination Date by the surrender
of this Warrant and the Notice of Exercise Form annexed hereto duly executed, at
the office of the Company (or such other office or agency of the Company as it
may designate by notice in writing to the registered Holder at the address of
such Holder appearing on the books of the Company) and upon payment of the
Exercise Price of the shares thereby purchased by wire transfer or cashier's
check drawn on a United States bank, the Holder shall be entitled to receive a
certificate for the number of Warrant Shares so purchased. Certificates for
shares purchased hereunder shall be delivered to the Holder within three (3)
Trading Days after the date on which this Warrant shall have been exercised as
aforesaid. This Warrant shall be deemed to have been exercised and such
certificate or certificates shall be deemed to have been issued, and Holder or
any other person so designated to be named therein shall be deemed to have
become a holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior
to the issuance of such shares, have been paid.

        (b)    If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the certificate or certificates representing
Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder
to purchase the unpurchased Warrant Shares called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

        (c)    Notwithstanding anything herein to the contrary, in no event
shall the Holder be permitted to exercise this Warrant for Warrant Shares to the
extent that (i) the number of shares of Common Stock owned by such Holder (other
than Warrant Shares issuable upon exercise of this Warrant) plus (ii) the number
of Warrant Shares issuable upon exercise of this Warrant, would be equal to or
exceed 4.999% of the number of shares of Common Stock then issued and
outstanding, including shares issuable upon exercise of this Warrant held by
such Holder after application of this Section 3(c). As used herein, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange
Act. To the extent that the limitation contained in this Section 3(c) applies,
the determination of whether this Warrant is exercisable (in relation to other
securities owned by the Holder) and of which a portion of this Warrant is
exercisable shall be in the sole discretion of such Holder, and the submission
of a Notice of Exercise shall be deemed to be such Holder's determination of
whether this Warrant is exercisable (in relation to

<PAGE>

                                        3

other securities owned by such Holder) and of which portion of this Warrant is
exercisable, in each case subject to such aggregate percentage limitation, and
the Company shall have no obligation to verify or confirm the accuracy of such
determination. Nothing contained herein shall be deemed to restrict the right of
a Holder to exercise this Warrant into Warrant Shares at such time as such
exercise will not violate the provisions of this Section 3(c). The provisions of
this Section 3(c) may be waived by the Holder upon, at the election of the
Holder, not less than 61 days' prior notice to the Company, and the provisions
of this Section 3(c) shall continue to apply until such 61st day (or such later
date, as determined by the Holder, as may be specified in such notice of
waiver). No exercise of this Warrant in violation of this Section 3(c) but
otherwise in accordance with this Warrant shall affect the status of the Warrant
Shares as validly issued, fully-paid and nonassessable.

4.      No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

5.      Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

6.      Closing of Books. The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant.

7.      Transfer, Division and Combination.

        (a)    Subject to compliance with any applicable securities laws,
transfer of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company, together with
a written assignment of this Warrant substantially in the form attached hereto
duly executed by the Holder or its agent or attorney and funds sufficient to pay
any transfer taxes payable upon the making of such transfer. In the event that
the Holder wishes to transfer a portion of this Warrant, the Holder shall
transfer at least 25,000 shares underlying this Warrant to any such transferee.
Upon such surrender and, if required, such payment, the Company shall execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees
and in the denomination or denominations specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A
Warrant, if properly assigned, may be exercised by a new holder for the purchase
of Warrant Shares without having a new Warrant issued. Notwithstanding the
above, the Holder shall not transfer this Warrant or any rights hereunder to any
person or entity which is then engaged in a business that is in the reasonable
judgement of the Company is in direct competition with the Company.

<PAGE>

                                        4

        (b)    This Warrant may be divided or combined with other Warrants
upon presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by the Holder or its agent or attorney. Subject to
compliance with Section 7(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

        (c)    The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

        (d)    The Company agrees to maintain, at its aforesaid office, books
for the registration and the registration of transfer of the Warrants.

8.      No Rights as Shareholder until Exercise. This Warrant does not entitle
the Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price, the Warrant Shares so purchased shall be and be
deemed to be issued to such Holder as the record owner of such shares as of the
close of business on the later of the date of such surrender or payment.

9.      Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants
that upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

10.     Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

11.     Adjustments of Exercise Price and Number of Warrant Shares/Stock Splits,
etc. The number and kind of securities purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment from time to time
upon the happening of any of the following. In case the Company shall (i) pay a
dividend in shares of Common Stock or make a distribution in shares of Common
Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding
shares of Common Stock into a greater number of shares, (iii) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, or (iv) issue any shares of its capital stock in a reclassification of
the Common Stock, then the number of Warrant Shares purchasable upon exercise of
this Warrant immediately prior thereto shall be adjusted so that the Holder
shall be entitled to receive the kind and number of Warrant Shares or other
securities of the Company which it would have owned or have been entitled to
receive had such Warrant been exercised in advance thereof. Upon each such
adjustment of the kind and number of Warrant Shares or other securities of the
Company which are purchasable hereunder, the Holder shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment

<PAGE>

                                        5

by the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

12.     Reorganization, Reclassification, Merger, Consolidation or Disposition
of Assets. In case the Company shall reorganize its capital, reclassify its
capital stock, consolidate or merge with or into another corporation (where the
Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or otherwise dispose of all or substantially all its property, assets or
business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at
their option, (a) upon exercise of this Warrant, the number of shares of Common
Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event, or (b) cash equal to the value of
this Warrant as determined in accordance with the Black-Sholes option pricing
formula. In case of any such reorganization, reclassification, merger,
consolidation or disposition of assets, the successor or acquiring corporation
(if other than the Company) shall expressly assume the due and punctual
observance and performance of each and every covenant and condition of this
Warrant to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of Warrant Shares for which
this Warrant is exercisable which shall be as nearly equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "common stock of the successor or acquiring corporation" shall include stock
of such corporation of any class which is not preferred as to dividends or
assets over any other class of stock of such corporation and which is not
subject to redemption and shall also include any evidences of indebtedness,
shares of stock or other securities which are convertible into or exchangeable
for any such stock, either immediately or upon the arrival of a specified date
or the happening of a specified event and any warrants or other rights to
subscribe for or purchase any such stock. The foregoing provisions of this
Section 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

13.     Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant reduce the then current Exercise Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the
Company.

14.     Notice of Adjustment. Whenever the number of Warrant Shares or number or
kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
Holder notice of such adjustment or adjustments setting forth the

<PAGE>

                                        6

number of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

15.     Notice of Corporate Action. If at any time:

        (a)    the Company shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

        (b)    there shall be any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

        (c)    there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such disposition, dissolution, liquidation or winding up. Each
such written notice shall be sufficiently given if addressed to Holder at the
last address of Holder appearing on the books of the Company and delivered in
accordance with Section 17(d).

                                        7

16.     Authorized Shares. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the principal market
upon which the Common Stock may be listed.

        The Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

        Before taking any action which would result in an adjustment in the
number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

17.     Miscellaneous.

        (a)    Jurisdiction. This Warrant shall constitute a contract under the
laws of Ontario, without regard to its conflict of law, principles or rules, and
be subject to arbitration pursuant to the terms set forth in the Purchase
Agreement.

        (b)    Restrictions. The Holder acknowledges that the Warrant Shares
acquired upon the exercise of this Warrant, if not registered, will have
restrictions upon resale imposed by state and federal securities laws.

        (c)    Nonwaiver and Expenses. No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully and knowingly fails to comply with any provision of this
Warrant, which results in any material damages to the Holder, the Company shall
pay to Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys' fees, including
those of appellate proceedings,

<PAGE>

                                        8

incurred by Holder in collecting any amounts due pursuant hereto or in otherwise
enforcing any of its rights, powers or remedies hereunder.

        (d)    Notices. Any notice, request or other document required or
permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.

        (e)    Limitation of Liability. No provision hereof, in the absence of
affirmative action by Holder to purchase Warrant Shares, and no enumeration
herein of the rights or privileges of Holder, shall give rise to any liability
of Holder for the purchase price of any Common Stock or as a stockholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

        (f)    Remedies. Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive the defense in any action for specific performance that a remedy at law
would be adequate.

        (g)    Successors and Assigns. Subject to applicable securities laws,
this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to
be for the benefit of all Holders from time to time of this Warrant and shall be
enforceable by any such Holder or holder of Warrant Shares.

        (h)    Amendment. This Warrant may be modified or amended or the
provisions hereof waived with the written consent of the Company and the Holder.

        (i)    Severability. Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

        (j)    Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

          restrictions in the jurisdiction in which it resides, confirms that no

<PAGE>

                                        2

1.   Title to Warrant. Prior to the Termination Date and subject to compliance
with applicable laws, this Warrant and all rights hereunder are transferable, in
whole or in part, at the office or agency of the Company by the Holder in person
or by duly authorized attorney, upon surrender of this Warrant together with the
Assignment Form annexed hereto properly endorsed.

2.   Authorization of Shares. The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights represented by this Warrant,
be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such issue).

3.   Exercise of Warrant.

     (a)  Except as provided in Section 4 herein, exercise of the purchase
rights represented by this Warrant may be made at any time or times on or after
the Initial Exercise Date and on or before the Termination Date by the surrender
of this Warrant and the Notice of Exercise Form annexed hereto duly executed, at
the office of the Company (or such other office or agency of the Company as it
may designate by notice in writing to the registered Holder at the address of
such Holder appearing on the books of the Company) and upon payment of the
Exercise Price of the shares thereby purchased by wire transfer or cashier's
check drawn on a United States bank, the Holder shall be entitled to receive a
certificate for the number of Warrant Shares so purchased. Certificates for
shares purchased hereunder shall be delivered to the Holder within three (3)
Trading Days after the date on which this Warrant shall have been exercised as
aforesaid. This Warrant shall be deemed to have been exercised and such
certificate or certificates shall be deemed to have been issued, and Holder or
any other person so designated to be named therein shall be deemed to have
become a holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior
to the issuance of such shares, have been paid.

     If this Warrant shall have been exercised in part, the Company shall, at
the time of delivery of the certificate or certificates representing Warrant
Shares, deliver to Holder a new Warrant evidencing the rights of Holder to
purchase the unpurchased Warrant Shares called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

     Notwithstanding anything herein to the contrary, in no event shall the
Holder be permitted to exercise this Warrant for Warrant Shares to the extent
that (i) the number of shares of Common Stock owned by such Holder (other than
Warrant Shares issuable upon exercise of this Warrant) plus (ii) the number of
Warrant Shares issuable upon exercise of this Warrant, would be equal to or
exceed 4.999% of the number of shares of Common Stock then issued and
outstanding, including shares issuable upon exercise of this Warrant held by
such Holder after application of this Section 3(c). As used herein, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange
Act. To the extent that the limitation contained in this Section 3(c) applies,
the determination of whether this Warrant is exercisable (in relation to other
securities owned by the Holder) and of which a portion of this Warrant is
exercisable shall be in the sole discretion of such Holder, and the submission
of a Notice of Exercise shall be deemed to be such Holder's determination of
whether this Warrant is exercisable (in relation to

<PAGE>

                                        3

other securities owned by such Holder) and of which portion of this Warrant is
exercisable, in each case subject to such aggregate percentage limitation, and
the Company shall have no obligation to verify or confirm the accuracy of such
determination. Nothing contained herein shall be deemed to restrict the right of
a Holder to exercise this Warrant into Warrant Shares at such time as such
exercise will not violate the provisions of this Section 3(c). The provisions of
this Section 3(c) may be waived by the Holder upon, at the election of the
Holder, not less than 61 days' prior notice to the Company, and the provisions
of this Section 3(c) shall continue to apply until such 61st day (or such later
date, as determined by the Holder, as may be specified in such notice of
waiver). No exercise of this Warrant in violation of this Section 3(c) but
otherwise in accordance with this Warrant shall affect the status of the Warrant
Shares as validly issued, fully-paid and nonassessable.

4.   No Fractional Shares or Scrip. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to such fraction multiplied by the Exercise Price.

5.   Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

6.   Closing of Books. The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant.

7.   Transfer, Division and Combination.

     (a)  Subject to compliance with any applicable securities laws, transfer of
this Warrant and all rights hereunder, in whole or in part, shall be registered
on the books of the Company to be maintained for such purpose, upon surrender of
this Warrant at the principal office of the Company, together with a written
assignment of this Warrant substantially in the form attached hereto duly
executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. In the event that the
Holder wishes to transfer a portion of this Warrant, the Holder shall transfer
at least 25,000 shares underlying this Warrant to any such transferee. Upon such
surrender and, if required, such payment, the Company shall execute and deliver
a new Warrant or Warrants in the name of the assignee or assignees and in the
denomination or denominations specified in such instrument of assignment, and
shall issue to the assignor a new Warrant evidencing the portion of this Warrant
not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if
properly assigned, may be exercised by a new holder for the purchase of Warrant
Shares without having a new Warrant issued. Notwithstanding the above, the
Holder shall not transfer this Warrant or any rights hereunder to any person or
entity which is then engaged in a business that is in the reasonable judgement
of the Company is in direct competition with the Company.

<PAGE>

                                        4

     (b)  This Warrant may be divided or combined with other Warrants upon
presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by the Holder or its agent or attorney. Subject to
compliance with Section 7(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

     (c)  The Company shall prepare, issue and deliver at its own expense
(other than transfer taxes) the new Warrant or Warrants under this Section 7.

     (d)  The Company agrees to maintain, at its aforesaid office, books for
the registration and the registration of transfer of the Warrants.

8.   No Rights as Shareholder until Exercise. This Warrant does not entitle the
Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price, the Warrant Shares so purchased shall be and be
deemed to be issued to such Holder as the record owner of such shares as of the
close of business on the later of the date of such surrender or payment.

9.   Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants
that upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

10.  Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

11.  Adjustments of Exercise Price and Number of Warrant Shares/Stock Splits,
etc. The number and kind of securities purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment from time to time
upon the happening of any of the following. In case the Company shall (i) pay a
dividend in shares of Common Stock or make a distribution in shares of Common
Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding
shares of Common Stock into a greater number of shares, (iii) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, or (iv) issue any shares of its capital stock in a reclassification of
the Common Stock, then the number of Warrant Shares purchasable upon exercise of
this Warrant immediately prior thereto shall be adjusted so that the Holder
shall be entitled to receive the kind and number of Warrant Shares or other
securities of the Company which it would have owned or have been entitled to
receive had such Warrant been exercised in advance thereof. Upon each such
adjustment of the kind and number of Warrant Shares or other securities of the
Company which are purchasable hereunder, the Holder shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment

<PAGE>

                                       5

by the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

12.  Reorganization, Reclassification, Merger, Consolidation or Disposition of
Assets. In case the Company shall reorganize its capital, reclassify its capital
stock, consolidate or merge with or into another corporation (where the Company
is not the surviving corporation or where there is a change in or distribution
with respect to the Common Stock of the Company), or sell, transfer or otherwise
dispose of all or substantially all its property, assets or business to another
corporation and, pursuant to the terms of such reorganization, reclassification,
merger, consolidation or disposition of assets, shares of common stock of the
successor or acquiring corporation, or any cash, shares of stock or other
securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of
the successor or acquiring corporation ("Other Property"), are to be received by
or distributed to the holders of Common Stock of the Company, then the Holder
shall have the right thereafter to receive, at their option, (a) upon exercise
of this Warrant, the number of shares of Common Stock of the successor or
acquiring corporation or of the Company, if it is the surviving corporation, and
Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a Holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event, or (b) cash equal to the value of this Warrant
as determined in accordance with the Black-Sholes option pricing formula. In
case of any such reorganization, reclassification, merger, consolidation or
disposition of assets, the successor or acquiring corporation (if other than the
Company) shall expressly assume the due and punctual observance and performance
of each and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be deemed appropriate (as determined in
good faith by resolution of the Board of Directors of the Company) in order to
provide for adjustments of Warrant Shares for which this Warrant is exercisable
which shall be as nearly equivalent as practicable to the adjustments provided
for in this Section 12. For purposes of this Section 12, "common stock of the
successor or acquiring corporation" shall include stock of such corporation of
any class which is not preferred as to dividends or assets over any other class
of stock of such corporation and which is not subject to redemption and shall
also include any evidences of indebtedness, shares of stock or other securities
which are convertible into or exchangeable for any such stock, either
immediately or upon the arrival of a specified date or the happening of a
specified event and any warrants or other rights to subscribe for or purchase
any such stock. The foregoing provisions of this Section 12 shall similarly
apply to successive reorganizations, reclassifications, mergers, consolidations
or disposition of assets.

13.  Voluntary Adjustment by the Company. The Company may at any time during the
term of this Warrant reduce the then current Exercise Price to any amount and
for any period of time deemed appropriate by the Board of Directors of the
Company.

14.  Notice of Adjustment. Whenever the number of Warrant Shares or number or
kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
Holder notice of such adjustment or adjustments setting forth the

<PAGE>

                                        6

number of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

15.  Notice of Corporate Action.  If at any time:

     (a)  the Company shall take a record of the holders of its Common Stock for
the purpose of entitling them to receive a dividend or other distribution, or
any right to subscribe for or purchase any evidences of its indebtedness, any
shares of stock of any class or any other securities or property, or to receive
any other right, or

     (b)  there shall be any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

     (c)  there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such disposition, dissolution, liquidation or winding up. Each
such written notice shall be sufficiently given if addressed to Holder at the
last address of Holder appearing on the books of the Company and delivered in
accordance with Section 17(d).

<PAGE>

16.  Authorized Shares. The Company covenants that during the period the Warrant
is outstanding, it will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of the Warrant Shares
upon the exercise of any purchase rights under this Warrant. The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant. The Company will take all
such reasonable action as may be necessary to assure that such Warrant Shares
may be issued as provided herein without violation of any applicable law or
regulation, or of any requirements of the principal market upon which the Common
Stock may be listed.

     The Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

     Before taking any action which would result in an adjustment in the
number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

17.  Miscellaneous.

     (a)  Jurisdiction. This Warrant shall constitute a contract under the laws
of Ontario, without regard to its conflict of law, principles or rules, and be
subject to arbitration pursuant to the terms set forth in the Purchase
Agreement.

     (b)  Restrictions. The Holder acknowledges that the Warrant Shares
acquired upon the exercise of this Warrant, if not registered, will have
restrictions upon resale imposed by state and federal securities laws.

     (c)  Nonwaiver and Expenses. No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully and knowingly fails to comply with any provision of this
Warrant, which results in any material damages to the Holder, the Company shall
pay to Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys' fees, including
those of appellate proceedings,

                                       3

<PAGE>

incurred by Holder in collecting any amounts due pursuant hereto or in otherwise
enforcing any of its rights, powers or remedies hereunder.

     (d)  Notices. Any notice, request or other document required or
permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.

     (e)  Limitation of Liability. No provision hereof, in the absence of
affirmative action by Holder to purchase Warrant Shares, and no enumeration
herein of the rights or privileges of Holder, shall give rise to any liability
of Holder for the purchase price of any Common Stock or as a stockholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

     (f)  Remedies. Holder, in addition to being entitled to exercise all rights
granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of this Warrant and hereby agrees to waive the
defense in any action for specific performance that a remedy at law would be
adequate.

     (g)  Successors and Assigns. Subject to applicable securities laws, this
Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to
be for the benefit of all Holders from time to time of this Warrant and shall be
enforceable by any such Holder or holder of Warrant Shares.

     (h)  Amendment. This Warrant may be modified or amended or the provisions
hereof waived with the written consent of the Company and the Holder.

     (i)  Severability. Wherever possible, each provision of this Warrant shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provisions
or the remaining provisions of this Warrant.

     (j)  Headings. The headings used in this Warrant are for the convenience of
reference only and shall not, for any purpose, be deemed a part of this Warrant.

Ladies and Gentlemen:

          Reference is made to the Subscription Agreement and all Exhibits
thereto (the "Agreement"), dated as of * day of June, 2002, between Aton Select
Fund Ltd. and API Electronics Group Inc. (the "Company"). Pursuant to the
Agreement, and subject to the terms and conditions set forth in the Agreement,
the company has issued to the Investor shares of the Company's common shares
(the "Common Stock"), and (ii) warrants to purchase up to 100,000 shares of
Common Stock (the "Warrants"). The number of Shares and Warrants issued to the
Investor is as follows:

     --------------------------------------------------------------------
                       INVESTOR          COMMON STOCK        WARRANTS
     --------------------------------------------------------------------
       1. Aton Select Fund Ltd.            100,000            100,000
     --------------------------------------------------------------------

          As a condition to the effectiveness of the Agreement, the Company has
agreed to issue to you, as the transfer agent for the Common Stock (the
"Transfer Agent"), these instructions relating to the Common Stock to be issued
to the Investor (or a permitted assignee) pursuant to the Agreement at the
Closing of the Agreement and upon the exercise of the Warrants. All capitalized
terms used herein and not otherwise defined shall have the meaning set forth in
the Agreement.

     1.   ISSUANCE OF COMMON STOCK WITHOUT THE LEGEND

     Pursuant to the Agreement, the Company has sold at the Closing Shares and
     Warrants as described in the [legal opinion of * ]. Such Shares and
     Warrants have been sold to the Investor, which is a non-U.S. Person,
     pursuant to Regulation S under the U.S. Securities Act of 1933 as amended
     (the "Securities Act"). The Transfer Agent shall be entitled to rely on
     such advice and such opinion. The Transfer Agent shall deliver to the
     Investor certificates representing Common Stock not bearing the Legend
     without requiring further advice or instruction or additional documentation
