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 February 28, 2010 and November 30, 2009,  the results of its  operations
     for the three-month  periods ended February 28, 2010 and February 28, 2009,
     and its cash flows for the three-month  periods ended February 28, 2010 and
     February 28, 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  three-month  period ended  February 28,
     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

     The Company has completed the development of a fully  operational 40MM long
     range  LEKTROX,  a unique line of wireless  electric  ammunition for use in
     military,  homeland  security,  law enforcement,  and professional and home
     security  scenarios and the Company is now planning for a production  line.
     LEKTROX has been  specially  designed for use with standard issue riot guns
     and M203  grenade  launchers.  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 an arm's length.  2nd  generations  were the
     wired electric charge solutions.  3rd generations are the wireless electric
     bullets.

     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 LEKTROX,
     which is

     currently being evaluated by the US Military.  The Company's future success
     is dependent upon its continued ability to raise sufficient capital to fund
     operating  expenses and the  economic  production  of LEKTROX.  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  to raising of  appropriate
     capital in the near future.  During the year ended  November 30, 2009,  the
     Company  was able to raise  $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.

     The Company has  incurred a loss of $546,540  during the three month period
     ended  February 28, 2010  primarily  due to its  research  and  development
     activities.  At February 28, 2010, the Company had an  accumulated  deficit
     during the  development  stage of  $14,600,228  which  includes a non- cash
     stock based compensation expense of $4,998,912 and compensation expense for
     warrants for $361,317.

3.   RESEARCH AND PRODUCT DEVELOPMENT

     Research and Product  Development  costs,  including  acquired research and
     product  development  costs,  are  charged  against  income  in the  period
     incurred.

     Year ended November 30, 2009
     ----------------------------

     On August 19, 2009 the  Company  sold  788,000  units to a group of private
     investors.  Each  unit  consisted  of one  share of  common  stock  and one
     warrant.  Each  warrant  allows  the  holder to  purchase  one share of the
     Company's  common  stock at a price of $0.50 per share at any time prior to
     June 15,  2010.  The  shares  were sold at a price of $0.25  per unit.  The
     shares of common  stock are, and any shares  issuable  upon the exercise of
     warrants will be,  restricted  securities,  as that term is defined in Rule
     144 of the Securities and Exchange Commission.  The Company relied upon the
     exemption  provided  by  Section  4(2)  of the  Securities  Act of  1933 in
     connection

     Three month period ended February 28, 2010
     ------------------------------------------

     On January 4, 2010 the Company completed the placement for 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.  The  Company  paid
     $20,000  as  finder's  fees.  The  shares  of common  stock are  restricted
     securities,  as that  term is  defined  in Rule 144 of the  Securities  and
     Exchange  Commission.  The Company  relied upon the  exemption  provided by
     Section 4(2) of the Securities Act of 1933 in this connection.

6.   STOCK BASED COMPENSATION

     On December 4, 2009,  the Company  approved  the  reduction of the exercise
     price of 300,000  outstanding  options  which had earlier  been issued at a
     price of $0.50 to a new  option  price of $0.25 per  share,  with all other
     terms of the original grant  remaining the same. The Company  expensed this
     additional  non-cash  stock  based  compensation  expense  relating to this
     modification for $6,534. The fair value of each option used for the purpose
     of estimating the stock  compensation is calculated using the Black-Scholes
     option pricing model with the following weighted average assumptions:

          On December 4, 2009, the Company approved the extension of the
          expiration of 2,900,000 outstanding options from their initial expiry
          date ranging from November 2011 to April 2013 to a new expiration date

          On January 4, 2010, the board of directors granted options to a
          director to acquire 100,000 common shares at an exercise price of
          $0.25 per share. All of these options vested immediately and have an
          expiry of five years. The Company expensed stock based compensation
          cost of $23,677. The fair value of each option used for the purpose of
          estimating the stock compensation is calculated using the
          Black-Scholes option pricing model with the following weighted average
          assumptions:

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

     SDI was  incorporated on March 1, 2005 and for the period from inception to
February 28, 2010 has not generated any revenue.

     During the three months ended February 28, 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 prior period.

     During the period from inception  (March 1, 2005) through February 28, 2010
SDI's operations used $8,278,756 in cash. During this period SDI:

     o    purchased $50,521 of equipment;
     o    raised  $8,274,150  (net) 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.

     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 the Company completed the placement for 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.

     As of February 28, 2010 SDI had  developed a fully  operational  Long Range
LEKTROX (40MM) and was planning a production line.

     SDI anticipates that its capital  requirements for the twelve-month  period
ending February 28, 2011 will be:

         Development and Preproduction costs                   $1,500,000
         General and Administrative Expenses                      375,000
                                                               -----------
                Total                                          $1,875,000
                                                               ===========

     Other than the foregoing,  SDI did not have any material future contractual
obligations or off balance sheet arrangements as of February 28, 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. The Company paid $20,000 as finder's
fees in connection with the sale of these shares.

     SDI relied upon the  exemption  provided by Section 4(2) of the  Securities
Act of 1933 with respect to the sale of these securities.  The investors in this
offering were provided with full information regarding SDI. There was no general
solicitation  in connection  with this private  offering.  The investors in this
offering  acquired  SDI's  securities for their own accounts.  The  certificates
representing  the shares of common stock issued to the investors bear restricted
legends providing that the shares cannot be sold except pursuant to an effective
registration statement or an exemption from registration.

Item 4 and 4T.  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, 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  February 28, 2010,
that materially  affected,  or are reasonably likely to materially  affect,  its
internal control over financial reporting.
