Condensed Notes to Interim Financial Statements

(Amounts expressed in US Dollars)
(Unaudited-Prepared by Management)


1. BASIS OF PRESENTATION

        The accompanying unaudited consolidated financial statements do not
        include all the information and footnotes required by generally accepted
        accounting principles for complete financial statements. In the opinion
        of management, all adjustments (consisting of all recurring accruals)
        considered necessary for fair presentation have been included. Operating
        results for the interim period are not necessarily indicative of the
        results that may be expected for the year ended November 30, 2009.
        Interim financial statements should be read in conjunction with the
        company's annual audited financial statements for the year ended
        November 30, 2008.

        The Company was incorporated under the laws of the state of Delaware on
        March 1, 2005. The interim financial statements include the accounts of
        Security Devices International Inc. (the "Company").

     2. NATURE OF OPERATIONS

        The Company is currently in the advanced stages of developing LEKTROX, a
        unique line of wireless electric ammunition for use in military,
        homeland security, law enforcement, and professional and home security
        scenarios. LEKTROX has been specially designed for use with standards
        issue riot guns, M203 grenade launchers and regular 12-guage shotguns.
        This will allow military, law enforcement agencies etc. to quickly
        deploy LEKTROX without the need for lengthy, complex training methods or
        significant functional adjustments to vehicles or personal equipment.
        Simplicity of use is also a key benefit for the home security market
        where most users have little or no specialized training. LEKTROX is a
        3rd generation electric solution. First generation solutions were
        electric batons and hand-held stun guns which had a range of arm's
        length. 2nd generations were the wired electric charge solutions. 3rd
        generations are the wireless electric bullets. Currently, there is still
        no 3rd generation wireless electric bullet on the market.

        The Company is in the development stage and has not yet realized
        revenues from its planned operations. The Company has incurred a loss of
        $ 808,578 during the three month period ended February 28, 2009. At
        February 28, 2009, the Company had an accumulated deficit during the
        development stage of $11,887,799 which includes a non- cash stock based
        compensation expense of $4,842,117. During the first quarter of 2007,
        the company raised $1,170,670 through issue of common stock. During the
        second quarter of 2007, the Company raised an additional $4,688,375 (net
        of expenses of $279,375) through the issue of Common stock. Further,
        during the last quarter of 2008, the Company received $11,700 due to the
        exercise of stock options. The Company did not raise any funds during
        the three months ended February 28, 2009.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operation

      Securities Devices International, Inc. was incorporated on March 1, 2005
and as of March 31, 2009 has not yet generated any revenue. SDI is a defense
technology company which is developing LEKTROX, a unique line of wireless
electric ammunition for use in military, homeland security, law enforcement, and
professional and home security situations.

      During the year ended November 30, 2008, and the three months ended
February 28, 2009, substantially all of SDI's cash expenses were related to the
development of its LEKTROX technology.

      During the three months ended February 28, 2009:

     o    general  and  administrative  expenses  decreased  primarily  due to a
          decline  in  stock  based  compensation.  General  and  administrative
          expenses  included charges of $114,688,  which did not require the use
          of cash,  associated  with  lowering  the  exercise  price of  certain
          options granted to SDI's officers, directors and consultants.

     o    Research and Product Development  expenses were approximately the same
          as those incurred during the three months ended February 29, 2008.

      During the period from inception (March 1, 2005) through February 28, 2009
SDI's operations used $(6,265,860) in cash. During this period SDI:

     o    purchased $40,141 of equipment;
     o    raised $7,719,650 from the sale of shares of its common stock; and
     o    raised  $106,700  from three of its  officers and  directors  upon the
          exercise of options to purchase 1,067,000 shares of common stock.

Item 4.  Controls and Procedures.

      (a) SDI maintains a system of controls and procedures designed to ensure
that information required to be disclosed in reports filed or submitted under
the Securities Exchange Act of 1934, as amended ("1934 Act"), is recorded,
processed, summarized and reported, within time periods specified in the SEC's
rules and forms and to ensure that information required to be disclosed by SDI
in the reports that it files or submits under the 1934 Act, is accumulated and
communicated to SDI's management, including its Principal Executive Officer and
Principal Financial Officer, as appropriate to allow timely decisions regarding
required disclosure. As of February 28, 2009, SDI's Principal Executive Officer
and Principal Financial Officer evaluated the effectiveness of the design and
operation of SDI's disclosure controls and procedures. Based on that evaluation,
the Principal Executive Officer and Principal Financial Officer concluded that
SDI's disclosure controls and procedures were effective.

control over financial reporting during the quarter ended February 28, 2009,
that materially affected, or are reasonably likely to materially affect, its
internal control over financial reporting.
