1.    BASIS OF PRESENTATION

       The accompanying unaudited condensed financial statements have been
       prepared in accordance with the instructions to Form 10-Q and therefore
       do not include all information and footnotes necessary for a fair
       presentation of financial position, results of operations and cash flows
       in conformity with U.S. generally accepted accounting principles (GAAP);
       however, such information reflects all adjustments (consisting solely of
       normal recurring adjustments), which are, in the opinion of management,
       necessary for a fair statement of the results for the interim periods.

       The condensed financial statements should be read in conjunction with the
       financial statements and Notes thereto together with management's
       discussion and analysis of financial condition and results of operations
       contained in the Company's annual report on Form 10-K for the year ended
       November 30, 2009. In the opinion of management, the accompanying
       condensed financial statements reflect all adjustments of a normal
       recurring nature considered necessary to fairly state the financial
       position of the Company at August 31, 2010, the results of its operations
       for the nine -and three-month periods ended August 31, 2010 and August
       31, 2009, and its cash flows for the nine -month periods ended August 31,
       2010 and August 31, 2009. In addition, some of the Company's statements
       in this quarterly report on Form 10-Q may be considered forward-looking
       and involve risks and uncertainties that could significantly impact
       expected results. The results of operations for the nine -month period
       ended August 31, 2010 are not necessarily indicative of results to be
       expected for the full year.

       The Company was incorporated under the laws of the state of Delaware on
       March 1, 2005.

2.   NATURE OF OPERATIONS AND GOING CONCERN

     Nature of Operations:

     The Company is a defense technology corporation specializing in the
     development of innovative next generation solutions for security situations
     that do not require the use of lethal force or ammunition. The Company is
     currently in the advanced stages of developing and deploying their patent
     pending LEKTROX family of products. These products consist of; the Wireless
     Electric Projectile 40mm (WEP40), and the Blunt Impact Projectile 40mm
     (BIP40).

2.   NATURE OF OPERATIONS AND GOING CONCERN-Cont'd

     Going Concern:

     The Company's financial  statements are presented on a going concern basis,
     which   contemplates   the  realization  of  assets  and   satisfaction  of
     liabilities in the normal course of business. The Company has no source for
     operating  revenue  and  expects  to  incur  expenses  before  establishing
     operating revenue. The Company has a need for additional working capital to
     fund its operating expenses and for the economic  production of its LEKTROX
     products.  This raises  substantial  doubt about the  Company's  ability to
     continue as a going  concern.  The financial  statements do not include any
     adjustments  that might result from this  uncertainty.  In order to finance
     the  continued  development,  the  Company  is working  towards  raising of
     appropriate capital in the near future.  During the year ended November 30,
     2009,  the  Company  raised  $197,000  through  issue of common  shares and
     warrants. The Company further raised an additional $357,500 net through the
     issue of common shares  during the quarter  ended  February 28, 2010 and an

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operation

     SDI is a defense technology corporation  specializing in the development of
innovative next generation solutions for security situations that do not require
the use of lethal force or ammunition.  SDI is currently in the advanced  stages
of developing  and deploying  their patent  pending  LEKTROX family of products.
These products consist of; the Wireless  Electric  Projectile 40mm (WEP40),  and
the Blunt  Impact  Projectile  40mm  (BIP40).  The WEP40 when  deployed  emits a
Wireless Electro-Muscular  Disruption Technology that incapacitates the targeted
individual.  The BIP40 is a  non-electrical  ammunition  round that will stop an
individual with targeted  accuracy.  Market sectors for these products  include;
the military,  army, navy, air force,  peacekeeping,  homeland security, and law
enforcement  professionals.  SDI's  products  were  designed for a standard 40mm
ammunition  casing,  for use with  standard  issue weapons such as riot guns and
M203 grenade launchers.

      SDI was incorporated on March 1, 2005 and for the period from inception to
August 31, 2010 has not generated any revenue.

      During the three and nine months ended August 31, 2010:

          o Research and Product Development expenses were lower since the
            development of the Company's products was nearing completion.
          o General and administrative expenses were comparable with the prior
            periods.

      During the period from inception (March 1, 2005) through August 31, 2010
SDI's operations used $8,980,774 in cash. During this period SDI:

          o     purchased $50,521 of equipment;
          o     raised $9,159,150 (net) from the sale of shares of its common
                stock;
          o     raised  $117,500  from two of its officers and  directors  and
                a former  officer and  director  upon the exercise of options to
                purchase  1,175,000  shares of common stock; and

      In August 2009 SDI sold, in a private offering, 788,000 Units at a price
of $0.25 per Unit. Each Unit consisted of one share of SDI's common stock and
one warrant. Each warrant allows the Holder to purchase one additional share of
SDI's common stock at a price of $0.50 per share at any time on or before June
15, 2010.

      On January 4, 2010 SDI sold 1,510,000 common shares to private investors.
The shares were sold at a price of $0.25 per common share for a total
consideration of $377,500.

      In April, 2010 SDI received a subscription from a private investor for the
sale of 250,000 common shares at a price of $0.20 per share.

      In May, 2010, SDI received $10,800 from the exercise of options to acquire
108,000 common shares at a price of $0.10 per share.


                                       16



      On May 30, 2010 Sheldon Kales resigned as a director of SDI and as SDI's
Principal Executive Officer.

      On May 30, 2010 Gregory Sullivan was appointed as SDI's President and
Principal Executive Officer.

      On June 8, 2010 Harry Walters and Patrick Bryan were appointed directors
of SDI.

      On June 1, 2010 SDI sold 1,000,000 shares of common stock to a private
investor at a price of $0.20 per share.

      During the three months ended August 31, 2010 SDI sold 1,500,000 shares of
its common stock to a group of private investors at a price of $0.20 per share.

      SDI anticipates that its capital requirements for the twelve-month period
ending August 31, 2011 will be:

      Development and Preproduction costs         $2,250,000
      General and Administrative Expenses            750,000
                                                ------------
           Total                                  $3,000,000
                                                ============

      Other than the foregoing, SDI did not have any material future contractual
obligations or off balance sheet arrangements as of August 31, 2010.

      SDI does not have any commitments or arrangements from any persons to
provide SDI with any additional capital it may need. Without additional capital
SDI will not be able to fund its anticipated capital requirements outlined
above.

                                     PART II

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

      In January 2010 SDI sold, in a private offering, 1,510,000 shares of its
common stock at a price of $0.25 per share. SDI paid $20,000 as finder's fees in
connection with the sale of these shares.

      In April, 2010 SDI received a subscription from a private investor for the
sale of 250,000 common shares at a price of $0.20 per share.

      In May, 2010, SDI received $10,800 from the exercise of options to acquire
108,000 common shares at a price of $0.10 per share.

      During the three months ended August 31, 2010 SDI sold 1,500,000 shares of
its common stock to a group of private investors at a price of $0.20 per share.

      SDI relied upon the exemption provided by Section 4(2) of the Securities
Act of 1933 in connection with the sale of these securities. The investor which




                                       17


acquired the shares was sophisticated and was provided with full information
regarding SDI. There was no general solicitation in connection with the offer or
sale of the securities. The investor which acquired these securities acquired
them for its own account. The certificate representing these securities bears a
restricted legend providing that they cannot be sold except pursuant to an
effective registration statement or an exemption from registration. No
commission or other form of remuneration was given to any person in connection
with the sale of these securities.

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 August 31, 2010, 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,
SDI's Principal Executive Officer and Principal Financial Officer concluded that
SDI's disclosure controls and procedures were effective.

      (b) Changes in Internal Controls. There were no changes in SDI's internal
control over financial reporting during the quarter ended August 31, 2010, that
materially affected, or are reasonably likely to materially affect, its internal
control over financial reporting.
