You should read the cautionary statements made below as being applicable to all forward-looking statements wherever they appear in this document.

Business

History

Security Devices International Inc. was incorporated on March 1, 2005. The Company began as a research and development company focused on the development of 40mm less-lethal ammunition. 40mm refers to the diameter of the bullet (sometimes also referred to as a round or a projectile) and bullets of this size are required for standard issue military riot guns. 40mm bullets are also the emerging standard among riot guns used by police forces, although many police forces are currently using 37mm riot guns.

The Company began with development of a wireless electric projectile (a “WEP”), named the Lektrox. The Company hired Elad Engineering Ltd. (“Elad”) a ballistics engineering firm located in Tel Aviv, Israel, to collaborate in the development of the WEP. The WEP uses mini-harpoons to fix the bullet to the target's clothing or body. The bullet contains an electrical system that releases a charge that imitates the electro-neural impulses used by the human body. Sending out a control signal to the muscles, this high- voltage low- current pulse overrides the target's nervous system inducing a muscle spasm that causes the target to fall to the ground helpless.

Commencing in December 2008, the Joint Non-Lethal Weapons Directorate (“JNLWD”) of the US Department of Defense, an organization responsible for the development and coordination of non-lethal weapons activities within the United States, tested the WEP through its evaluation facility at Penn State University. The testing evaluated the effectiveness and safety of the electrical output compared to the Government’s standard total body effects model. Testing was completed in November 2009 and a report was prepared by Penn State University and submitted to the JNLWD in January 2010. An executive summary was released to the Company indicating a positive outcome. Research and development continued on the WEP until mid-2010.

To reduce kinetic energy levels, the head of the WEP contains a cushioning mechanism composed of a collapsible material that enlarges the contact surface and absorbs part of the impact. In June 2010, the Company began development of a 40mm blunt impact projectile (the “BIP”) which used the cushioning mechanism of the WEP but did not contain the electrical mechanism of the WEP. The BIP used the pain of impact to obtain compliance from the target.

In the fall of 2010 the Company underwent a change in the board of directors and management. Two new directors were appointed and the board of directors appointed a Chief Operating Officer. The Company contracted with Level 4 Capital Corp. to assist with restructuring of the Company, contract negotiations and operational issues.

Early in 2011 the Company decided to focus its attention on the BIP and to discontinue further development work on the WEP. The Company concluded that the cost and time required to complete development and testing of the BIP were significantly less than that required to complete development and testing of the WEP. The BIP is also less expensive to produce than the WEP, and can be sold for a lower price. The Company plans to use revenue received from BIP sales to complete the development and production line for the WEP.

Initially, the Company’s products were designed, tested and assembled in Israel. In 2011, the Company moved its engineering, intellectual property and production facilities from Tel Aviv, Israel to the operator (the “BIP Manufacturer”) of an injection molding facility outside of Boston, Massachusetts. The BIP Manufacturer has a history of manufacturing 40mm components for the military sector, and provides molding services to the medical, aerospace, petrochemical, commercial, electronics, and defense industries.

The Company attended several military tradeshows through 2011 and signed a teaming agreement with Chemring Ordnance Inc. (“Chemring”), of Perry, Florida in December 2011. The agreement gives Chemring the non-exclusive right to market and sell the BIP worldwide for a five- year term. Chemring is responsible for its costs of marketing the BIPs and BIPs sold through this arrangement will bear the Chemring brand. The Company has retained the right to market the BIP directly to military, law enforcement and government agencies outside of Chemring’s sales channels.

16

Research and development for the BIP was completed in the summer of 2012.

In October 2012, the Company obtained an ammunition certification from Chemring which meant that the BIP satisfied the standards set by Chemring for products which it would distribute.

In November 2012, the Company obtained a United States Department of Transportation number (DOT#) required in order for the Company to ship BIP rounds.

In June 2012, the Company contracted CRT Less Lethal Inc. (“CRT”) to test the BIP. CRT is a Seattle- based company founded in 2003 with expertise in the analysis, evaluation and human effects testing of less-lethal munitions. The testing protocol included accuracy, precision, consistency, muzzle and target energy, impact energy density and effective range of the BIP. Human volunteers were used during the test firing, revealing full effects to the lower body from the blunt trauma of the BIP. Extensive wound profiling from the tests were finalized in a detailed report from CRT. Based on data obtained from the three-stage evaluation, the BIP passed the CRT testing protocol for accuracy, consistency, relative safety and effectiveness.

In July 2012, the Company signed a five-year development, supply and manufacturing agreement with the BIP Manufacturer. An engineering team is available to the Company through the BIP Manufacturer for development of all of the core components of the BIP and any product changes that are necessary.

During 2012, the Company attended several law enforcement tradeshows and conducted live fire demonstrations with government agencies in Canada, and the US. Live fire demonstrations allow the Company to demonstrate the short and long distance firing capabilities, accuracy and relative safety of the BIP.

The Company has begun the development of five new less-lethal ammunition rounds. These new rounds will be a modified version of the BIP, four of which will carry a payload (a marking liquid, a marking powder, pepper spray and a pungent odor) and the fifth of which is a lower cost practice round. SDI expects to complete development of these five new ammunition rounds by the fourth quarter of calendar 2013. The Company has now moved into the testing phase with the payload rounds.

Products

SDI’s business is the development, manufacture and sale of less-lethal ammunition. This ammunition is used by the military and police forces for crowd control.

The Company has two products:

Less-Lethal Sector

Both military and law enforcement agencies are seeking alternatives to traditional lethal ammunition. From a military standpoint, the involvement of armed forces in populated areas has created a need for less-lethal ammunition. Police forces also require non-lethal ammunition for riot control and critical incident de-escalation, motivated in part by a desire to avoid expensive litigation.

17

Chemical irritants (such as tear gas) have been sporadically used by military and have been adopted by police forces around the world for use in riot control.

Throughout the 1970’s and 1980’s the military and police forces began to use kinetic energy impact projectiles. These projectiles included wood, rubber and bean-bag material as ammunition. Many of these projectiles are still being used by military and police forces around the world. There has been very little technology progression within this space over the last half a century.

The rubber bullet was developed by the Ministry of Defense for the British Army in Northern Ireland at the request of army officers who wanted a weapon for use in civil disturbances with a range beyond a stone-throwing distance. In management’s opinion, rubber bullets are inaccurate and have unpredictable ricochets. In addition, management believes that they have caused numerous severe injuries and several deaths.

The nature of a military’s role has changed significantly to the extent that the military becomes actively engaged in the policing of civilian populations. This is where the military in effect, intersects with local police forces to support and uphold national and regional law. Today, military units are involved in on-going conflicts that bring them into direct contact with civilian populations in Iraq, Afghanistan and various countries in the Middle East. Soldiers who are deployed in humanitarian roles are often subject to rules of engagement which disallow the use of deadly force unless soldiers encounter a lethal threat. The military requires less-lethal deterrent ammunition for use in crowd and riot control, perimeter security and pilfering situations. In management’s opinion, less-lethal ammunition means a greater opportunity to preserve life.

Police and military forces require easily applied options for riot control without the consequences of lethal force. In addition to the litigation, administrative and financial resources required to defend the use of lethal force, there is a moral consideration as well. Police and military forces must balance the risk of injury or death to their own personnel against the risk of injury to civilians, including bystanders. Riot control involves difficult and challenging decision that often must be made within seconds.

Both police and military personnel are demanding access to options that fall somewhere between physically charging into a crowd with batons and firing munitions designed to kill targets. If these personnel are equipped and trained with less-lethal munitions, they are better equipped to diffuse a riot and regain control. By providing soldiers and police with a midlevel force response, appropriate to the level of threat, the chance of an escalation can be reduced. In addition, if this less-lethal response can be employed at a standoff distance, the troops or officers can maintain a buffer zone between themselves and the crowd. The capability to target a specific individual, as opposed to spraying an entire crowd, reduces the risk of injury to innocent bystanders and political backlash.

Conflicts in Iraq and Afghanistan, events such as the August 2011 UK riots, and the June 2012 Quebec student street violence have led governments, police and defense decision-makers to seek cost effective less-lethal weapons. These decision-makers understand that social media will limit the use of lethal weapons and a new generation of less-lethal weapons is required.

Going Concern

These unaudited interim financial statements have been prepared in accordance with generally accepted accounting principles applicable to a going concern, which assumes that the Company will be able to meet its obligations and continue its operations for its next fiscal year. At May 31, 2013, the Company has no source of operating cash flows, has not achieved profitable operations, and has accumulated losses of $20,328,556 since inception and expects to incur further losses in the development of its business. These factors cast substantial doubt about the Company’s ability to continue as a going concern. The Company has a need for additional working capital to launch its blunt impact and electric 40mm round products, meet its ongoing levels of corporate overhead, and discharge its liabilities as they come due.

In order to finance the continued development, the Company is working towards the raising of appropriate capital in the near future. In addition to raising funds in the prior years, the Company raised $160,000 through the issuance of 800,000 common shares during the year ended November 30, 2011. The Company further raised an additional $878,328 by issue of Convertible Debentures during the year ended November 30, 2011 and $910,000 during the year ended November 30, 2012. In addition, the Company raised $649,750 by issuance of 2,165,834 common shares during the year ended November 30, 2012. The Company has filed a final prospectus in Canada (Ontario, Alberta and British Columbia) to raise additional funds in accordance with the terms of the prospectus

While the Company has been successful in securing financings in the past, there is no assurance that it will be able to do so in the future. These financial statements do not give effect to adjustments, if any, that would be necessary should the Company be unable to continue as a going concern.

At May 31, 2013, the Company had an accumulated deficit during the development stage of $20,328,556 which includes a non-cash stock based compensation expense of $6,585,016 for issue of options and warrants.

(c) The Company filed a prospectus in Canada and an S-1 registration statement in the USA to raise funds as per the prospectus. The Company has incurred additional legal and other general and administrative expenses in 2013 as compared to $nil in 2012.

The major components of change for (ii) relate to:

a) During the six month period ended May 31, 2013, the board of directors granted 325,000 warrants to various lenders (includes 50,000 warrants to a director) who provided a working capital loan of $628,550 (CAD $650,000). These warrants were issued at an exercise price of $0.50 per share and vest immediately with an expiry term of two years. The fair value of the warrants issued for the purpose of estimating the stock compensation was calculated using the Black-Scholes option pricing model at $99,245.

b) During the six month period ended May 31, 2012, the board of directors granted options to three directors to acquire a total of 775,000 common shares, one officer to acquire 20,000 common shares and two consultants to acquire a total of 110,000 common shares. The 905,000 options were issued at an exercise price of $0.13 per share and vest immediately with an expiry term of four years. The fair value of the options issued for the purpose of estimating the stock compensation was calculated using the Black-Scholes option pricing model at $113,292.

c) During the six month period ended May 31, 2012, the board of directors issued warrants to a Company in which the Chief Operating officer has an interest in, to acquire a total of 800,000 common shares. These warrants were issued at an exercise price of $0.13 per share with an expiry term of four years. The fair value of the options issued for the purpose of estimating the stock compensation was calculated using the Black-Scholes option pricing model at $100,148.

The major components of change for (iii) relate to:

On November 30, 2009, the Company entered into a Memorandum of Understanding (“MOU”) with its former research and development services contractor Elad Engineering Ltd. (“Elad’) to settle their liability. On March 13, 2012, the Company entered into a definitive agreement with Elad to settle the accounts payable. Elad had previously performed services for the development of a less-than-lethal-electric-projectile and blunt impact projectile. At the date of the settlement agreement, the Company owed Elad $315,143.The Company and Elad agreed to irrevocably waive and release each other from any claim, demand or action in connection with services provided, upon payment of $100,000 by the Company to Elad no later than March 20, 2012. The $100,000 payment was made on March 20, 2012. The Company recorded the reduction of the payable in the amount of $215,143 during the period ended May 31, 2012 as recovery of research and development product development cost. This was measured as the difference between the amount payable to Elad and the settlement amount.

21

Liquidity and Capital Resources

As at May 31, 2013, cash was $79,214, as compared to $232,471 at November 30, 2012. This decrease is mainly attributable to the combination of factors mentioned above under heading “Cash Flows”.

The major components are as follows; cash $79,214; prepaid expenses and other receivables $6,127; deferred costs for $93,730; accounts payable and accrued liabilities of $341,455; loan from non- related parties for $531,850 and loan from related party for $96,700. The Company filed a prospectus in Canada to raise gross proceeds of CDN$3,000,000 with net proceeds of CDN$2,730,000. After meeting all of its obligations for sales and marketing, operations, general and administration, repayment of Bridge Loans and other expenses, the Company believes it will have a surplus of unallocated working capital to fund ongoing operations in excess of $250,000.

At November 30, 2012, the Company had a working capital of $121,803. The major components are as follows; cash $232,471; prepaid expenses and other receivables $7,200; deferred costs for $32,500 and accounts payable and accrued liabilities of $150,368

There are no assurances that the Company can continue to raise equity financing to fund its operations. SDI does not have any commitments or arrangements from any persons to provide SDI with any additional capital it may need.

SDI entered into an agreement (the “Teaming Agreement”) dated November 30, 2011 with Chemring Ordnance, Inc. (“Chemring”) pursuant to which both agreed to establish a co-operative and supportive team to develop the best marketing, management and technical approach for the worldwide manufacture and sale of 40mm less that blunt trauma ammunition. The Teaming Agreement provides for SDI and Chemring to create a team for the purpose of preparing competitive, cost effective proposals in response to requests for proposals and obtaining and performing any contracts that result therefrom.

Pursuant to the Teaming Agreement, if a contract is awarded, each of SDI and Chemring will perform the work to be done by it as specified in the Teaming Agreement and will share the revenue as set out in the Teaming Agreement. Either party who initiated the proposal that led to the contract will be the prime contact for that customer.

In accordance with the Teaming Agreement, the BIP ammunition sold will have Chemring’s branding unless otherwise agreed by the parties.

The Teaming Agreement will terminate on December 20, 2016. The Teaming Agreement may also expire if a time period of two years from the effective date of the agreement passes without a bona fide arms length contract being executed and delivered with respect to BIP ammunition.

Revenue Recognition

The Company’s revenue recognition policies are expected to follow common practice in the manufacturing industry. The Company will record revenue when it is realized, or realizable and earned. The Company considers revenue to be realized, or realizable and earned, when the following revenue recognition requirements will be met: persuasive evidence of an arrangement exists; the products or services have been accepted by the customer via delivery or installation acceptance; the sales price is fixed or determinable; and collectability is probable. For product sales, the Company determines that the earnings process is complete when title, risk of loss and the right to use equipment has transferred to the customer.

Outstanding share data

As of July 15, 2013, the Company had 33,273,913 issued and outstanding shares of common stock

24

Risk Factors

We may not successfully commercialize any of our products or earn a profit.

We have incurred losses since incorporation. As of May 31, 2013, we have an accumulated total deficit of $20,328,556. To date, we have experienced negative cash flow from development of our products. We currently have not generated any revenue from operations and expect to incur substantial net losses for the foreseeable future to further develop and commercialize our products. We cannot predict the extent of these future net losses, or when we may attain profitability, if at all. If we are unable to generate significant revenue from our products or attain profitability, we will not be able to sustain operations.

Because of the numerous risks and uncertainties associated with developing and commercializing our products, we are unable to predict the extent of any future losses or when we will become profitable, if ever. We may never become profitable and you may never receive a return on an investment in our common stock. An investor in our common stock must carefully consider the substantial challenges, risks and uncertainties inherent in a developmental stage company. The Common Shares must be considered highly speculative due to the nature of the Company’s business, the early stage of its deployment, its current financial position and ongoing requirements for capital. An investment in the Common Shares should only be considered by those persons who can afford a total loss of investment, and is not suited to those investors who may need to dispose of their investment in a timely fashion. We may never successfully commercialize our products, and our business may fail. Investors should consult with their own professional advisors to assess the legal, financial and other aspects of an investment in Common Shares.

We need substantial additional capital to grow and fund our present and planned business and business strategy.

We anticipate expending substantial funds to carry out the development, introduction and manufacture of additional products. We have no source of operating cash flow to fund all of its operational needs and will require additional financing to continue its operations. As such, our current and planned operations contemplate funding in the future through one or more public or private equity financings, by taking on debt financing, or from other sources. There can be no assurance that such financing will be available on favorable terms or at all. If such funds are unavailable or are only available at a prohibitive cost, we may have to significantly curtail its product development program or seek funds through financing alternatives that may require us to sell its rights to certain products or certain marketing territories. Failure to meet funding milestones may have a significant adverse effect on our growth and we may have to curtail our business strategy. Failure to obtain such additional financing could result in delay or indefinite postponement of the deployment of our products. If we receive less funding than planned, we will have to revise our business model and reduce proposed plans. Without significant funding, we will not be able to execute on our business operations and may be forced to cease operations. At this time, there can be no assurance we will be able to obtain the funding we need and even if we obtain such funding that it will be on terms and conditions favorable to us and our existing shareholders. Without funding we will not be able to proceed with planned operations or meet existing obligations.

We did not have a meeting of our shareholders from inception until March 15, 2013.

We did not have an annual general meeting of the shareholders since it was formed on March 1, 2005. Our Bylaws and the General Corporation Law of the State of Delaware requires us to have an annual general meeting of shareholders to elect directors. Pursuant to the laws of the State of Delaware, the failure to hold an annual meeting of stockholders does not automatically invalidate all corporate actions. However, it is unclear if all such actions would be deemed valid if challenged in a court of law. We had an annual general meeting of our shareholders on March 15, 2013.

25

There is substantial doubt as to our ability to continue as a going concern.

Due to our recurring losses from operations, there is substantial doubt about our ability to continue as a going concern, meaning that we may not be able to continue in operation for the foreseeable future or be able to realize assets and discharge liabilities in the ordinary course of operations. Our audited financial statements for the year ended November 30, 2012 were prepared assuming that we will continue as a going concern. However, the report of our independent registered public accounting firm stated there was substantial doubt about our ability to continue as a going concern. Such an opinion could materially limit our ability to raise additional funds through the issuance of new debt or equity securities or otherwise. There is no assurance that sufficient financing will be available when needed to allow us to continue as a going concern. The perception that we may not be able to continue as a going concern may cause others to choose not to deal with us due to concerns about our ability to meet our contractual obligations.

There can be no assurance that we can generate substantial revenue growth, or that any revenue growth that is achieved can be sustained.

Revenue growth that we have achieved or may achieve may not be indicative of future operating results. In addition, we may increase further its operating expenses in order to fund higher levels of research and development, increase its sales and marketing efforts and increase its administrative resources in anticipation of future growth. To the extent that increases in such expenses precede or are not subsequently followed by increased revenues, the Company’s business, operating results and financial condition will be materially adversely affected.

We are dependent on certain members of our management.

The loss of the services of one or more of them could adversely affect us. Our ability to maintain its competitive position is dependent upon its ability to attract and retain highly qualified managerial, specialized technical, manufacturing, sales and marketing personnel. There can be no assurance that we will be able to continue to recruit and retain such personnel. Our inability to recruit and retain such personnel would adversely affect our operations and product development.

We are dependent on key suppliers

We purchase certain key components of its products from a limited number of key suppliers. Failure of a supplier to provide sufficient quantities on favorable terms or on a timely basis could result in possible lost sales.

We may be subject to product or warranty claims that could have a material adverse effect on our business, operating results and financial condition.

We may be subject to proceedings or claims that may arise in the ordinary conduct of the business, which could include product and service warranty claims, which could be substantial. If our products fail to perform as warranted and we fail to quickly resolve product quality or performance issues in a timely manner, sales may be lost and we may be forced to pay damages. Any failure to meet customer requirements could materially affect our business, results of operations and financial condition. The occurrence of product defects and the inability to correct errors could result in the delay or loss of market acceptance of our products, material warranty expense, diversion of technological and other resources from our product development efforts, and the loss of credibility with customers, manufacturer’s representatives, distributors, value added resellers, systems integrators, original equipment manufacturers and end-users, any of which could have a material adverse effect on our business, operating results and financial condition.

We currently have general liability insurance, which includes product liability coverage. There is no assurance this insurance policy will cover all potential claims which may have a material adverse effect on the business or financial condition of the Company. A product recall could have a material adverse effect on our business or financial condition.

26

We rely upon, and expect to rely upon, strategic alliances with original equipment manufacturers for the manufacturing and distribution of its products.

There can be no assurance that such strategic alliances can be achieved or that the Company will be able to maintain existing strategic alliances or that we will achieve our goals.

In order to commercialize its technology, we must either acquire or develop an internal marketing and sales force with technical expertise and supporting distribution capabilities or arrange for third parties to perform these services.

In order to market any of our products, we must either acquire or develop a sales and distribution infrastructure. The acquisition or development of a sales and distribution infrastructure would require substantial resources, which may divert the attention of our management and key personnel, and defer our product development and deployment efforts. To the extent that we into marketing and sales arrangements with other companies, our revenues will depend on the efforts of others. These efforts may not be successful. If we fail to develop substantial sales, marketing and distribution channels, or to enter into arrangements with third parties for those purposes, we will experience delays in product sales and incur increased costs, which may affect our business, operating results and financial condition.

The markets for our products and services are characterized by rapidly changing technology and evolving industry standards, which could result in product obsolescence or short product life cycles.

Accordingly, our success is dependent upon its ability to anticipate technological changes in the industries it serves and to successfully identify, obtain, develop and market new products that satisfy evolving industry requirements.

There can be no assurance that we will successfully develop new products or enhance and improve its existing products or that any new products and enhanced and improved existing products will achieve market acceptance. Further, there can be no assurance that competitors will not market products that have perceived advantages over the our products or which render the products currently sold by us obsolete or less marketable.

We must commit significant resources to developing new products before knowing whether its investments will result in products the market will accept. To remain competitive, we may be required to invest significantly greater resources then currently anticipated in research and development and product enhancement efforts, and result in increased operating expenses. There can be no assurance that we will have adequate capital to meet these demands.

Our industry is highly competitive and composed of many domestic and foreign companies.

We have experienced and expect to continue to experience, substantial competition from numerous competitors with greater resources and whom we expect to continue to improve their products and technologies. Competitors may announce and introduce new products, services or enhancements that better meet the needs of end-users or changing industry standards, or achieve greater market acceptance due to pricing, sales channels or other factors. Competitors may be able to respond more quickly than we can to changes in end-user requirements and devote greater resources to the enhancement, promotion and sale of their products.

We are materially dependent on acceptance of our products by the law enforcement, both domestic and international, and federal markets. If law enforcement agencies choose not to purchase our products, our revenues will be adversely affected.

A substantial number of law enforcement and corrections agencies may not purchase our products. Law enforcement and corrections agencies may be influenced by claims or perceptions that WEPs and BIPs (each as hereinafter defined), such as our products, are unsafe or may be used in an abusive manner. Sales of our products to these agencies may also be delayed or limited by these claims or perceptions.

Most of our end-user customers are subject to budgetary and political constraints, particularly in the currently challenging economic environment, that may delay or prevent sales.

Most of our end-user customers are government agencies. These agencies often do not set their own budgets and therefore, have limited control over the amount of money they can spend. In addition, these agencies experience political pressure that may dictate the manner in which they spend money. As a result, even if an agency wants to acquire our products, it may be unable to purchase them due to budgetary or political constraints. Currently, many governmental agencies are continuing to experience severe budgetary constraints. There can be no assurance that the economic and budgeting issues will not worsen and adversely impact sales of our products. Some government agency orders may also be canceled or substantially delayed due to budgetary, political or other scheduling delays which frequently occur in connection with the acquisition of products by such agencies and such cancellations may accelerate or be more severe than we have experienced historically as a result of the current economic environment.

We may face personal injury, wrongful death and other liability claims that harm our reputation and adversely affect our sales and financial condition.

Our products can be used in aggressive confrontations that may result in serious, permanent bodily injury or death to those involved. Our products may be associated with these injuries. A person injured in a confrontation or otherwise in connection with the use of our products may bring legal action against us to recover damages on the basis of theories including personal injury, wrongful death, negligent design, defective product or inadequate warning. We are currently subject to a number of such lawsuits. We may also be subject to lawsuits involving allegations of misuse of our products. If successful, personal injury, misuse and other claims could have a material adverse effect on our operating results and financial condition and could result in negative publicity about our products. Although we carry product liability insurance, we do incur significant legal expenses within our self-insured retention in defending these lawsuits and significant litigation could also result in a diversion of management’s attention and resources, negative publicity and a potential award of monetary damages in excess of our insurance coverage. The outcome of any litigation is inherently uncertain and there can be no assurance that our existing or any future litigation will not have a material adverse effect on our revenues, our financial condition or financial results.

We face risks associated with rapid technological change and new competing products.

The technology associated with law enforcement devices is receiving significant attention and is rapidly evolving. While we have patent protection in key areas of our technology, it is possible that new technology may result in competing products that operate outside our patents and could present significant competition for our products.

We are subject to numerous and health and safety laws and regulations, which may require us to make substantial expenditures.

We are subject to numerous federal, state, local and foreign health and safety legislation and measures relating to the manufacture of ammunition. There can be no assurance that we will not experience difficulties with our efforts to comply with applicable regulations as they change in the future or that our continued compliance efforts (or failure to comply with applicable requirements) will not have a material adverse effect on our results of operations, business, prospects and financial condition. Our continued compliance with present and changing future laws could restrict our ability to modify or expand our facilities or continue production and could require us to acquire costly equipment or to incur other significant expense.

Health and safety and violations related to our products may arise that could lead to litigation or other action against us or to regulation of certain of our product components. We may also incur substantial penalties, civil and criminal sanctions, permit revocations and facility shutdowns. We may be required to modify our technology and may not be able to do so. We may also be required to pay damages that may reduce our profitability and adversely affect our financial condition. Additionally, future and health and safety laws and regulations or reinterpretation of current laws and regulations may require us to make substantial expenditures. Even if these concerns prove to be baseless, the resulting negative publicity could affect our ability to market our products. In turn, our costs to comply with, or any liabilities under, these laws and regulations could have a material adverse effect on our business, financial condition, cash flows and results of operations.

We may be unable to adequately protect or enforce our patents and proprietary rights.

Our future success depends, in part, on our ability to protect our intellectual property and maintain the proprietary nature of our technology through a combination of patents, licenses and other intellectual property arrangements, without infringing the proprietary rights of third parties. Although we consider certain of our product designs as well as manufacturing processes involving certain of its products to be proprietary, patents or copyrights do not protect all design and manufacturing processes. We have adopted procedures to protect its intellectual property and maintain secrecy of its confidential business information and trade secrets. However, there can be no assurance that such procedures will afford complete protection of such intellectual property, confidential business information and trade secrets. There can be no assurance that our competitors will not independently develop technologies that are substantially equivalent or superior to our technology.

We currently have 3 patents relating to our business and 1 patent pending. We cannot assure you that these pending patents will be issued or that any of our patents will be held valid if challenged, that any pending patent applications will issue, or that other parties will not claim rights in or ownership of our patents and other proprietary rights. Moreover, patents issued to us may be circumvented or fail to provide adequate protection. Our competitors might independently develop or patent technologies that are substantially equivalent or superior to our technologies. Since patent applications in the United States are not publicly disclosed until the patent is issued, applications may have been filed by others which, if issued as patents, could cover our products. We cannot be certain that others will not assert patent infringement claims or claims of misappropriation against us based on current or pending U.S. and/or foreign patents or trade secrets or that such claims will not be successful.

We also rely on trade secrets to develop and maintain our competitive position. Although we protect our proprietary technology in part by confidentiality agreements with our employees, consultants and corporate partners, we cannot assure you that these agreements will not be breached, that we will have adequate remedies for any breach or that our trade secrets will not otherwise become known or be discovered independently by our competitors. The failure to protect our intellectual property rights effectively or to avoid infringing the intellectual property rights of others could seriously harm our business, financial condition and results of operations and ability to achieve sufficient cash flow to service our indebtedness.

Our commercial success depends, in part, upon us not infringing intellectual property rights of others.

While we believe that our products and other intellectual property do not infringe upon the proprietary rights of third parties, our commercial success depends, in part, upon us not infringing intellectual property rights of others. A number of our competitors and other third parties have been issued or may have filed patent applications or may obtain additional patents and proprietary rights for technologies similar to those utilized by us. Some of these patents may grant very broad protection to the owners of the patents. We have not undertaken a review to determine whether any existing third party patents or the issuance of any third party patents would require us to alter its technology, obtain licenses or cease certain activities. We may become subject to claims by third parties that its technology infringes their intellectual property rights due to the growth of products in its target markets, the overlap in functionality of those products and the prevalence of products. We may become subject to these claims either directly or through indemnities against these claims that it provides to end-users, manufacturer’s representatives, distributors, value added resellers, system integrators and original equipment manufacturers.

Litigation may be necessary to determine the scope, enforceability and validity of third party proprietary rights or to establish our proprietary rights. Some of our competitors have, or are affiliated with companies having, substantially greater resources than us and these competitors may be able to sustain the costs of complex intellectual property litigation to a greater degree and for a longer period of time than us.

In addition, defending our company against these types of claims, regardless of their merits, could require us to incur substantial costs, divert the attention of key personnel and management, cause significant delays and materially disrupt the conduct of our business. Parties making these types of claims may be able to obtain injunctive or other equitable relief which could effectively block our ability to provide our services and could result in an award of substantial damages. In the event of a successful claim of infringement, we may need or be required to obtain one or more licenses from, as well as grant one or more licenses to, others. We cannot assure you that we could obtain necessary licenses from others at a reasonable cost or at all.

Regardless of their merit, any such claims could be time consuming to evaluate and defend, result in costly litigation, cause product shipment delays or stoppages, divert key personnel and management’s attention and focus away from the business, subject us to significant liabilities and equitable remedies, including injunctions, require us to enter into costly royalty or licensing agreements and require us to modify or stop using infringing technology Parties making these types of claims may be able to effectively block our ability to manufacture our products and could result in an award of substantial damages. In the event of a successful claim of infringement, we may be prohibited from developing or commercializing certain technologies and products unless it obtains a license from a third party or we may need or be required to grant one or more licenses to, others. There can be no assurance that we will be able to obtain any such license on commercially favorable terms or at all. If we do not obtain such a license, we could be required to cease the sale of certain products.

We are subject to currency and foreign exchange fluctuations

Fluctuations in the exchange rate between the United States dollar and the Canadian dollar may have a material effect on the our results of operations. To date, we have not engaged in exchange rate-hedging activities. To the extent that we may seek to implement hedging techniques in the future with respect to its foreign currency transactions, there can be no assurance that we will be successful in such hedging activities.

Stress in the global financial system may adversely affect our finances and operations in ways that may be hard to predict or to defend against.

Recent events have demonstrated that businesses and industries throughout the world are very tightly connected to each other. Thus, events seemingly unrelated to us, or to its industry, may adversely affect its finances or operations in ways that are hard to predict or defend against. For example, credit contraction in financial markets may hurt our ability to access credit when it is needed or rapid changes in foreign exchange rates may adversely affect financial results. Finally, a reduction in credit, combined with reduced economic activity, may adversely affect businesses and industries that collectively constitute a significant portion of our customer base. As a result, these customers may need to reduce their purchases of our products, or there may be greater difficulty in receiving payment for the products that these customers purchase from us. Any of these events, or any other events caused by turmoil in world financial markets, may have a material adverse effect on our business, operating results, and financial condition.

Our business is subject to a number of risks and hazards including industrial accidents, labor disputes, changes in the regulatory environment.

Such occurrences could result in damage to equipment, personal injury or death, monetary losses and possible legal liability. Although we maintain liability insurance in amounts which it considers adequate, the nature of these risks is such that liabilities might exceed policy limits, the liabilities and hazards might not be insurable, or we may elect not to insure against such liabilities due to high premium costs or other reasons, in which event we could incur significant costs that could have a materially adverse effect upon its financial position.

Certain of our directors and officers are or may become associated with other companies in the same or related industries which may give rise to conflicts of interest.

Directors who have a material interest in any person who is a party to a material contract or a proposed material contract with us are required, subject to certain exceptions, to disclose that interest and generally abstain from voting on any resolution to approve the contract. In addition, the directors and the officers are required to act honestly and in good faith with a view to our best interest Our directors and officers have either other full-time employment or other business or time restrictions placed on them and accordingly, we will not be the only business enterprise of these directors and officers.

We do not expect to pay dividends.

We have not paid dividends in the past and we do not expect to declare or pay any dividends on our common stock in the foreseeable future. The declaration and payment in the future of any cash or stock dividends on the common stock will be at the discretion of our board of directors and will depend upon a variety of factors, including our ability to service our outstanding indebtedness, if any, and to pay dividends on securities ranking senior to the common stock, our future earnings, if any, capital requirements, financial condition and such other factors as our board of directors may consider to be relevant from time to time. Our earnings, if any, are expected to be retained for use in expanding our business.

Our common stock is subject to volatility.

There can be no assurance that the market price for our common stock will remain at its current level and a decrease in the market price could result in substantial losses for investors. The market price of our common stock may be significantly affected by one or more of the following factors:

• announcements or press releases relating to the industry or to our own business or prospects;

• regulatory, legislative or other developments affecting us or the industry generally;

• sales by holders of restricted securities pursuant to effective registration statements or exemptions from registration;

• actual or anticipated fluctuations in our quarterly financial and operating results;

• our failure to meet the expectations of the investment community and changes in investment community recommendations or estimates of our future operating results;

• strategic moves by our competitors, such as product announcements or acquisitions;

• litigation;

• general market conditions;

• other domestic and international macroeconomic factors unrelated to our performance; and

• additions or departures of key personnel.

There is a very limited trading market for our shares and no active trading market may develop or be sustained.

Prior to the closing of the Offering, there has been a limited public market for the shares on the OTCBB in the United States. Trading prices and volumes on the OTC Bulletin Board are thin and erratic. The price paid for each Common Share under the Offering was determined by negotiation between us and the Canadian Agent; this price may bear no relation to the price at which our Common Shares will trade in the public market subsequent to the Offering. We can not predict at what price our Common Shares will trade and there can be no assurance that an active trading market in our Common Shares will develop or be sustained.

Our common stock trades on the OTCBB in the United States. As a result, there are additional risks associated with our common stock and you may be unable to liquidate your investment in our common stock quickly. The trading market for our shares is not always liquid. The market price of our shares has ranged from a high of $0.99 and a low of $0.10 during the twelve-month period ended May 31, 2013. The volume of shares traded at any one time can be limited, and, as a result, there may not be a liquid trading market for our shares.

29

There can be no assurance that an active market for our Common Shares will be sustained.

Securities of small and mid cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. These factors include global economic developments and market perceptions of the attractiveness of certain industries. The price per Common Share is also likely to be affected by change in our financial condition or results of operations as reflected in its quarterly filings. Other factors unrelated to our performance that may have an effect on the price of our Common Shares include the following: the extent of analytical coverage available to investors concerning our business may be limited if investment banks with research capabilities do not follow our securities; lessening in trading volume and general market interest in our securities may affect a subscriber’s ability to trade significant numbers of Common Shares, the size of our public float may limit the ability of some institutions to invest in our securities; a substantial decline in the price of our Common Shares that persists for a significant period of time could cause our securities to be delisted from an exchange, further reducing market liquidity. If an active market for our Common Shares does not continue, the liquidity of a subscriber’s investment may be limited and the price of our Common Shares may decline. If such a market does not develop, investors may lose their entire investment in our Common Shares.

Any changes in government policy may result in changes to laws affecting the sale of our products.

This may affect our ability to ship product in the future. The possibility that future governments may adopt substantially different policies, may also affect our operations. Local governments in all countries we deal with issue end user certificates to purchase or receive live ammunition from us. A change in policy may lead to a decision of these countries as to whether or not they will take possession or purchase such munitions. This may have a material adverse effect on our business, operating results, and financial condition.

Our common stock is classified as a “penny stock” under SEC Rules and Regulations, which means broker-dealers may experience difficulty in completing customer transactions and trading activity in our securities may be adversely affected.

The United States Securities and Exchange Commission (the “SEC”) has adopted Rule 15g-9 which generally defines "penny stock" to be any equity security that has a market price (as defined) less than USD$5.00 per share or an exercise price of less than $5.00 per share, subject to certain exceptions. Our shares are covered by the penny stock rules, which impose additional sales practice requirements on broker-dealers who sell to persons other than established customers and "accredited investors". The term "accredited investor" refers generally to institutions with assets in excess of USD$5,000,000 or individuals with a net worth in excess of USD$1,000,000 or annual income exceeding USD$200,000 or USD$300,000 jointly with their spouse. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC, which provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction and monthly account statements showing the market value of each penny stock held in the customer's account. The bid and offer quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer's confirmation. In addition, the penny stock rules require that prior to a transaction in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to the transaction. These disclosure requirements may have the effect of reducing the level of trading activity in the secondary market for the stock that is subject to these penny stock rules. Consequently, these penny stock rules may affect the ability of broker-dealers to trade our shares. We believe that the penny stock rules may discourage investor interest in and limit the marketability of our shares.

Due to the substantial instability in our common stock price, you may not be able to sell your shares at a profit or at all, and as a result, any investment in our shares could be totally lost.

The public market for our common stock is very limited. As with the market for many other small companies, any market price for our shares is likely to continue to be very volatile. Our common stock has very limited volume and as a “penny stock,” many brokers will not trade in our stock limiting our stocks’ liquidity. As such it may be difficult for you to sell shares of our common stock.

A decline in the price of our common stock could affect our ability to raise further working capital and adversely impact our operations.

A prolonged decline in the price of our common stock could result in a reduction in the liquidity of our common stock and a reduction in our ability to raise capital. Because our operations have been primarily financed through the sale of equity securities, a decline in the price of our common stock could be especially detrimental to our liquidity and our continued operations. Any reduction in our ability to raise equity capital in the future would force us to default on our debt obligations and forfeit our property interests or to reallocate funds from other planned uses. Either of these would have a significant negative effect on our business plans and operations, including our ability to acquire new property interests or fund our obligations for development of our current property interests. If our stock price declines, we may not be able to raise additional capital or generate funds from operations sufficient to meet our obligations.

Legal proceedings

There are no legal proceedings involving the Company or its assets which management of the Company believes to be material to the Company, nor are any such proceedings known by the Company to be contemplated.

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 May 31, 2013, 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 May 31, 2013 that materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
