THIS WARRANT AND THE SECURITIES DELIVERABLE UPON EXERCISE THEREOF HAVE NOT BEEN
REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S.
SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THIS
WARRANT MAY NOT BE EXERCISED IN THE UNITED STATES OR BY OR ON BEHALF OF A PERSON
IN THE UNITED STATES OR A U.S. PERSON UNLESS THE WARRANT AND THE UNDERLYING
SECURITIES HAVE BEEN REGISTERED UNDER THE U.S. SECURITIES ACT AND THE APPLICABLE
SECURITIES LEGISLATION OF ANY SUCH STATE OR AN EXEMPTION FROM SUCH REGISTRATION
REQUIREMENTS IS AVAILABLE. "UNITED STATES" AND "U.S. PERSON" ARE AS DEFINED IN
REGULATION S UNDER THE U.S. SECURITIES ACT.

                                                                         No. 2
                           AGENT'S WARRANT CERTIFICATE
                                                              Right to Purchase
                                                             7,025 Common Stock

                  WARRANT TO PURCHASE SHARES OF COMMON STOCK OF
                       SECURITY DEVICES INTERNATIONAL INC.

      On the terms hereof, this is to certify that FOR VALUE RECEIVED, Salman
Partners Inc., 17th Floor, 1095 West Pender Street, Vancouver, British Columbia
V6C 2M6, the registered holder hereof (the "Holder"), has the right to purchase
at any time and from time to time, up to and including 5:00 p.m. (Vancouver
time) on May 4, 2009 (the "Expiry Time"), 7,025 fully paid and non-assessable
shares (the "Common Stock") without par value in the capital stock of Security
Devices International Inc. (the "Company") as constituted on the date hereof at
a purchase price of U.S.$2.81 per Common Stock (the "Exercise Price"), on the
terms and subject to adjustment as hereinafter set forth.

      The Company agrees that the Common Stock so purchased shall be and be
deemed to be issued to the Holder as of the close of business on the date on
which this Agent's Warrant Certificate shall have been surrendered and payment
made for such shares as aforesaid.

      Nothing contained herein shall confer any right upon the Holder to
subscribe for or purchase any Common Stock of the Company at any time after the
Expiry Time, and from and after the Expiry Time, this Warrant and all rights
hereunder shall be void and of no value.

      The above provisions are, however, subject to the following:

     SECTION  1. - In the  event  the  Holder  desires  to  exercise  the  right
conferred  hereby to purchase  Common Stock in the capital of the  Company,  the
Holder  shall at or before the  Expiry  Time:  (a) duly  complete,  execute  and
deliver to the Company a  Subscription  Form for such  Common  Stock in the form
annexed hereto, together with any additional documentation required thereby, (b)
surrender this Agent's Warrant  Certificate to the Company at the address of the
Company indicated in Section 16 hereof, and (c) pay the aggregate Exercise Price
in respect of the Common  Stock in the  capital of the  Company  subscribed  for
either  in  cash,  by bank  draft or by  certified  cheque  drawn on a  Canadian


                                       1


chartered  bank and payable to the Company.  Upon such  delivery,  surrender and
payment as aforesaid and subject to the provisions  hereof,  the Holder shall be
deemed for all  purposes to be a  shareholder  of record of the number of Common
Stock in the  capital of the  Company  to be so issued  and the Holder  shall be
entitled to delivery of a certificate  or  certificates  evidencing  such shares
(which  certificates,  as well as all certificates  issued in exchange for or in
substitution  thereof,  shall bear any applicable  restrictive  legends) and the
Company  shall cause such  certificate  or  certificates  to be delivered to the
Holder at the address  specified  in said  Subscription  Form within ten days of
said surrender and payment as aforesaid.

      The Holder hereby acknowledges that these Warrants and the Common Stock
issuable hereunder have not been and will not be registered under the United
States Securities Act of 1933, as amended (the "U.S. Securities Act"), or the
securities laws of any state of the United States, and that these Agent's
Warrants may not be exercised in the United States or by or on behalf of a "U.S.
person," as such term is defined in Regulation S under the U.S. Securities Act,
nor may the Common Stock issuable hereunder be offered or sold in the United
States unless a registration statement has been filed and is effective or unless
an exemption from registration is available.

      SECTION 2. - The right to purchase Common Stock in the capital of the
Company conferred hereby may be exercised in whole or in part. In the event that
prior to the Expiry Time the Holder subscribes for and purchases any number of
Common Stock which is less than the number of shares referred to in this Agent's
Warrant Certificate, the Holder shall present the original of this Agent's
Warrant Certificate to the Company and the Holder will be entitled to receive a
further Agent's Warrant Certificate in respect of the Common Stock referred to
in this Agent's Warrant Certificate but not subscribed for.

      SECTION 3. - The Holder may transfer this Warrant subject to the
limitations noted on any legend appearing on this Agent's Warrant Certificate.
Subject to the foregoing, a transferee shall, by surrendering this Agent's
Warrant Certificate to the Company at the address of the Company indicated in
Section 16 hereof together with the Assignment completed by the Holder, be
entitled to become a registered holder and to receive a new Agent's Warrant
Certificate registered in the transferee's name in respect of the Common Stock
referred to in this Agent's Warrant Certificate and not then subscribed for.
Subject to the limitations noted on any legend on this Agent's Warrant
Certificate, the Company shall cause the new Agent's Warrant Certificate to be
delivered to the transferee at the address specified in the Assignment within
ten days of said surrender as aforesaid.

      SECTION 4. - This Agent's Warrant Certificate may be exchanged for Agent's
Warrant Certificates in any other denomination representing in the aggregate the
same number of underlying Common Stock. The Holder may exercise this right by
surrendering this Agent's Warrant Certificate, together with a written
direction, to the Company at the address of the Company indicated in Section 16
below and the Company shall cause the new Agent's Warrant Certificates to be
delivered to the Holder at the address specified in such direction within ten
days of said surrender as aforesaid.


                                       2


      SECTION 5. - In case this Agent's Warrant Certificate shall become
mutilated or be lost, destroyed or stolen, the Company shall, upon the Holder
complying with this Section 5, issue and deliver a new Agent's Warrant
Certificate of like date and tenor in exchange for and in place of the one
mutilated, lost, destroyed or stolen and upon surrender and cancellation of such
mutilated Agent's Warrant Certificate or in substitution for such lost,
destroyed or stolen Agent's Warrant Certificate. The applicant for the issue of
a new Agent's Warrant Certificate pursuant to this Section 5 shall bear the cost
of the issue thereof and in case of loss, destruction or theft shall, as a
condition precedent to the issue thereof, furnish to the Company such evidence
of ownership and of the loss, destruction or theft of the Agent's Warrant
Certificate so lost, destroyed or stolen as shall be reasonably satisfactory to
the Company and such applicant may be required to furnish an indemnity in amount
and form satisfactory to the Company.

      SECTION 6. - The holding of this Warrant shall not constitute the Holder a
shareholder of the Company nor entitle the Holder to any right or interest in
respect thereof except as herein expressly provided.

      SECTION 7. - The Company represents and warrants that:

      (a)   it is duly authorized to create and issue this Warrant;

      (b)   this Warrant is a valid and enforceable obligation of the Company in
            accordance with the terms hereof;

      (c)   it will take all such action as may be necessary to ensure that all
            Common Stock issuable hereunder, may be so issued without violation
            of any applicable requirements of any exchange or over-the-counter
            market upon which the Common Stock may be listed or in respect of
            which the Common Stock are qualified for unlisted trading
            privileges;

      (d)   the issuance of certificates of Common Stock upon the exercise of
            the Warrants shall be made without charge to the Holder for any
            issuance tax in respect thereto, provided that the Company shall not
            be required to pay any tax which may be payable in respect of any
            transfer involved in the issuance and delivery of any certificate in
            a name other than that of the Holder; and

      (e)   the Company will attend to all filings required to be made by the
            Company under applicable securities legislation in respect of the
            exercise of the Warrant in accordance with the terms hereof. For
            greater certainty, such requirement will not impose any obligation
            on the Company to file a prospectus or registration statement or
            similar document, or to become a reporting issuer or a registrant in
            any province, state or territory.

The Company  covenants and agrees that it will cause the Common Stock subscribed
for  and  purchased  in the  manner  herein  provided  and  the  certificate  or
certificates  evidencing  such Common  Stock to be duly issued and that,  at all
times prior to the Expiry Time, it shall reserve and there shall remain unissued


                                       3


out of its authorized capital a sufficient number of shares to satisfy the right
of purchase herein provided for. All Common Stock which shall be issued upon the
exercise of the right of purchase herein provided for, upon payment  therefor of
the aggregate Exercise Price for such Common Stock, shall be and be deemed to be
fully paid and  non-assessable and the Holder shall not be liable to the Company
or its creditors in respect thereof.

      SECTION 8. - In Section 8 and Section 9:

      "Equity Shares" means the Common Stock and any shares of any class or
series of the Company which may from time to time be authorized for issue if by
their terms such shares confer on the holders thereof the right to participate
in the distribution of assets upon the voluntary or involuntary liquidation,
dissolution, or winding-up of the Company beyond a fixed sum or a fixed sum plus
accrued dividends; and

      "Current Market Price" of the Common Stock at any date means the weighted
average price per share at which the Common Stock have traded on such stock
exchange or market on which the Common Stock are primarily traded as may be
selected by the directors of the Company (acting in good faith) during any 20
consecutive trading days ending not more than 5 days immediately preceding such
date. In the event the Common Stock are not listed on any stock exchange, the
Current Market Price of the Common Stock shall be determined by the directors
acting reasonably and in good faith.

      If at any time from May 4, 2007 and prior to the Expiry Time and while
this Warrant is outstanding there shall be a reclassification of the Common
Stock outstanding at any time or a change of the Common Stock into other shares
or securities, or any other capital reorganization except as described in
Section 9, or a consolidation, amalgamation or merger of the Company with or
into any other corporation (other than a consolidation, amalgamation or merger
which does not result in any reclassification of the outstanding Common Stock or
a change of the Common Stock into other shares or securities), or a transfer of
the undertaking or assets of the Company as an entirety or substantially as an
entirety to another corporation or other entity (any of such events being called
a "Capital Reorganization"), should the Holder exercise thereafter its right to
purchase Common Stock hereunder, the Holder shall be entitled to receive, and
shall accept for the same aggregate consideration, in lieu of the number of
Common Stock to which it was theretofore entitled upon the exercise of the right
to purchase Common Stock hereunder, the kind and amount of shares or other
securities or property which the Holder would have been entitled to receive as a
result of such Capital Reorganization if, on the effective date thereof, it had
been the registered holder of the number of Common Stock to which it was
theretofore entitled upon such exercise.

      If at any time from May 4, 2007 and prior to the Expiry Time and while
this Warrant is outstanding any adjustment in the Exercise Price shall occur as
a result of:

      (i)   an event referred to in Subsection 9(a); or

      (ii)  the fixing by the Company of a record date for an event referred to
            in Subsection 9(b),

                                       4


then the number of Common Stock purchasable upon any subsequent exercise of this
Warrant shall be simultaneously adjusted by multiplying the number of Common
Stock purchasable upon the exercise of this Warrant immediately prior to such
adjustment by a fraction which shall be the reciprocal of the fraction employed
in the adjustment of the Exercise Price. To the extent that any adjustment in
subscription rights occurs pursuant to this Section 8 as a result of a
distribution of exchangeable or convertible securities referred to in Subsection
9(a)(iii) other than Equity Shares or as a result of the fixing by the Company
of a record date for the distribution of rights, options or warrants referred to
in Subsection 9(b), the number of Common Stock purchasable upon the exercise of
the Warrant shall be readjusted immediately after the expiration of any relevant
exchange, conversion or exercise right to the number of Common Stock which would
be purchasable based upon the number of Common Stock actually issued and
remaining issuable immediately after such expiration, and shall be further
readjusted in such manner upon expiration of any further such right.

      SECTION 9. - The Exercise Price in effect at any date shall be subject to
adjustment from time to time as follows:

(a)   If and whenever at any time from May 4, 2007 and prior to the Expiry Time
      and while this Warrant is outstanding, the Company shall:

     (i)  subdivide the outstanding Common Stock into a greater number of Common
          Stock,

    (ii)  consolidate  the  outstanding  Common  Stock  into a lesser  number of
          Common Stock, or

   (iii)  make  any  distribution,  other  than  by  way of a  dividend  in the
          ordinary  course,  to the holders of all or  substantially  all of the
          outstanding  Common  Stock  payable  in  Common  Stock  or  securities
          exchangeable for or convertible into Common Stock,

(any of such events being called a "Common Share Reorganization"), the Exercise
Price shall be adjusted effective after the effective date or record date, as
the case may be, on which the holders of Common Stock are determined for the
purpose of the Common Share Reorganization by multiplying the Exercise Price in
effect immediately prior to such effective date or record date by a fraction,
the numerator of which shall be the number of Common Stock of the Company
outstanding on such effective date or record date before giving effect to such
Common Share Reorganization and the denominator of which shall be the number of
Common Stock outstanding immediately after giving effect to such Common Share
Reorganization including, in the case where securities exchangeable for or
convertible into Common Stock are distributed, the number of Common Stock that
would have been outstanding had all such securities been exchanged for or
converted into Common Stock on such record date. For purposes of this Subsection
9(a), "dividend in the ordinary course" means dividends having a value which
does not exceed, in the aggregate, the greater of (i) 50% of the retained
earnings of the Company as at the end of its immediately preceding fiscal year;
and (ii) 100% of the aggregate consolidated net income of the Company determined
before computation of extraordinary or unusual items, for its immediately
preceding fiscal year.

                                       5


(b)  If and  whenever  at any time from May 4, 2007 and prior to the Expiry Time
     and while this Warrant is outstanding,  the Company shall fix a record date
     for the issue of  rights,  options  or  warrants  to the  holders of all or
     substantially all of its outstanding  Common Stock under which such holders
     are entitled,  during a period expiring not more than ninety days after the
     record date for such issue,  to subscribe for or purchase Common Stock at a
     price per Common Share or having a conversion or exchange  price per Common
     Share less than 95% of the Current  Market  Price per Common  Share on such
     record date,  the Exercise Price shall be adjusted  immediately  after such
     record date so that it shall equal the price  determined by multiplying the
     Exercise  Price in effect on such record date by a fraction,  the numerator
     of which  shall be the total  number of Common  Stock  outstanding  on such
     record date plus a number  equal to the number  arrived at by dividing  the
     aggregate price of the total number of additional  Common Stock offered for
     subscription or purchase,  or the aggregate conversion or exchange price of
     the  convertible  securities so offered,  by such Current  Market Price per
     Common  Share,  and of which the  denominator  shall be the total number of
     Common  Stock  outstanding  on such  record  date plus the total  number of
     additional Common Stock offered for subscription or purchase (or into which
     the convertible securities so offered are convertible or exchangeable). Any
     Common  Stock  owned  by or held  for the  account  of the  Company  or any
     subsidiary  of the Company  shall be deemed not to be  outstanding  for the
     purpose of any such  computation.  To the extent that any adjustment in the
     Exercise Price occurs  pursuant to this  Subsection 9(b) as a result of the
     fixing by the  Company  of a record  date for the  distribution  of rights,
     options or warrants referred to in this Subsection 9(b), the Exercise Price
     shall be  readjusted  immediately  after  the  expiration  of any  relevant
     exchange,  conversion or exercise  right to the Exercise  Price which would
     then be in effect based upon the number of Common Stock actually issued and
     remaining  issuable after such expiration,  and shall be further readjusted
     in such manner upon expiration of any further such right.

      SECTION 10. - In any case in which it shall be required that an adjustment
shall become effective immediately after a record date for an event referred to
herein, the Company may defer, until the occurrence of such event,

(a)  issuing to the Holder,  if the Warrant is exercised  after such record date
     and before the  occurrence of such event (the date of such  exercise  being
     herein  referred to as the "Exercise  Date"),  the additional  Common Stock
     issuable  upon such exercise by reason of the  adjustment  required by such
     event, and

(b)  delivering  to the Holder any  distributions  declared with respect to such
     additional Common Stock after such Exercise Date and before such event,

provided, however, that the Company shall deliver to the Holder an appropriate
instrument evidencing its right, upon the occurrence of the event requiring the
adjustment, to an adjustment in the Exercise Price or the number of Common Stock
purchasable upon exercise of this Warrant and to such distributions declared
with respect to any such additional Common Stock issuable on the exercise of
this Warrant.


                                       6


      The adjustments provided for herein are cumulative; shall, in the case of
adjustments to the Exercise Price, be computed to the nearest one-tenth of one
cent; and shall apply (without duplication) to successive subdivisions,
consolidations, distributions, issuances or other events resulting in any
adjustment under the provisions hereof provided that, notwithstanding any other
provision hereof, no adjustment of the Exercise Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Exercise Price then in effect and no adjustment shall be made in the number of
Common Stock purchasable on the exercise of the Warrant unless it would result
in a change of at least one-hundredth of a share (provided, however, that any
adjustments which by reason of this Section 10 are not required to be made shall
be carried forward and taken into account in any subsequent adjustment).

      In the event of any question arising with respect to the adjustments
provided for herein such question shall be conclusively determined by a firm of
chartered accountants (who may be the Company's auditors) appointed by the
Company; such accountants shall have access to all necessary records of the
Company and such determination shall, in the absence of manifest error, be
binding upon the Company and the Holder.

      In case the Company after the date of this Warrant shall take any action
affecting the Common Stock, other than an action described herein, which in the
opinion of the directors of the Company would materially affect the rights of
the Holder, the Exercise Price and/or the number of Common Stock purchasable
upon exercise of this Warrant shall be adjusted, in such manner, if any, and at
such time, by action by the directors, in their discretion as they may determine
to be equitable in the circumstances. Failure of the directors to make an
adjustment in accordance with this Section 10 shall be conclusive evidence that
the directors have determined that it is equitable to make no adjustment in the
circumstances.

      If the Company shall set a record date to determine the holders of the
Common Stock for the purpose of entitling them to receive any issue or
distribution or for the issue of any rights, options or warrants and shall
thereafter and before such distribution or issue to such shareholders legally
abandon its plan to make such distribution or issue, then no adjustment in the
Exercise Price or the number of Common Stock purchasable upon exercise of this
Warrant shall be required by reason of the setting of such record date.

      In the absence of a resolution of the directors fixing a record date for
any of the events referred to in Subsection 9(b), the Company shall be deemed to
have fixed as the record date therefor the date on which any of such events is
effected.

      SECTION 11. - As a condition precedent to the taking of any action which
would require an adjustment pursuant to Sections 8 or 9, the Company shall take
any action which may, in the opinion of counsel, be necessary in order that the
Company may validly and legally issue as fully paid and non-assessable all the
Common Stock to which Holder is entitled to receive on the full exercise hereof
in accordance with the provisions hereof.

     SECTION 12. - At least ten days prior to the effective date or record date,
as the  case may be,  of any  event  which,  if  implemented,  will  require  an
adjustment in any of the subscription rights pursuant to this Warrant, including


                                       7


the Exercise Price and the number of Common Stock which are purchasable upon the
exercise hereof,  the Company shall give notice to the Holder of the particulars
of such event and, if determinable  and applicable,  the required or anticipated
adjustment and the computation of such adjustment.

      In case any adjustment for which a notice in this Section 12 has been
given is not then determinable, the Company shall promptly after such adjustment
is determinable give notice to the Holder of the adjustment and the computation
of such adjustment.

      SECTION 13. - The Company covenants and agrees that at the expense of the
Holder, it will do, acknowledge and deliver, or cause to be done, executed,
acknowledged and delivered, all such other acts, deeds and assurances as the
Holder shall reasonably require for the better accomplishing and completion of
the intentions and provisions of this Warrant.

      SECTION 14. - Time shall be of the essence hereof.

      SECTION 15. - This Warrant, any amendment, addendum, exhibit, supplement
or other document relating hereto, and any and all disputes arising herefrom or
related hereto, shall be governed by and construed in accordance with the
internal laws of the Province of Ontario, and the federal laws of Canada
applicable therein, governing disputes occurring, and contracts made and to be
performed, wholly therein, and without reference to its principles governing the
choice or conflict of laws. The parties hereto irrevocably attorn and submit to
the exclusive jurisdiction of the courts of the Province of Ontario, sitting in
the City of Toronto, with respect to any dispute related to or arising from this
Warrant.

      SECTION 16. - Any notice required or permitted to be given hereunder shall
be in writing and may be given by delivery or by facsimile transmission of same
addressed as follow:

      (i)  if to the Company: Security Devices International Inc. 120 Adelaide
           Street, Suite 2500 Toronto, Ontario M5H 1T1

           Attention: President

      (ii) if to the Holder, at the address shown on the first page of this
           Agent's Warrant Certificate.

      Any notice aforesaid shall, if delivered, be deemed to have been given and
received on the date on which it was delivered to the address provided herein
(if a business day, and if not, on the next succeeding business day) and if sent
by facsimile transmission be deemed to have been given and received at the time
of receipt unless actually received after 5:00 p.m. (Vancouver Time) at the
point of delivery in which case it shall be deemed to have been given and
received on the next business day. Any of such parties may change its address
for service from time to time by notice given in accordance with the foregoing.


                                       8


      SECTION 17. - This Warrant may be executed mechanically or by facsimile,
and in such case shall be deemed to be an original. In addition, this Warrant
shall enure to the benefit of the Holder and its successors and assigns and be
binding upon the Company and its successors including successors by way of
amalgamation.

IN WITNESS WHEREOF Security Devices  International  Inc. has caused this Agent's
