Caution Regarding Forward Looking Information



This Form 20-F (20-F) of Plaintree Systems Inc. (the Company or Plaintree) contains certain statements that to the extent not based on historical events, are forward-looking statements based on certain assumptions and reflects Plaintrees current expectations. Forward-looking statements include, without limitation, statements evaluating market and general economic conditions in the preceding sections, and statements regarding growth strategy and future-oriented project revenue, costs and expenditures. Actual results could differ materially from those projected and should not be relied upon as a prediction of future events. A variety of inherent risks, uncertainties and factors, many of which are beyond Plaintrees control, affect the operations, performance and results of Plaintree and its business, and could cause actual results to differ materially from current expectations of estimated or anticipated events or results. Some of these risks, uncertainties and factors include the impact or unanticipated impact of: companies evaluating Plaintrees products delaying purchase decisions; current, pending and proposed legislative or regulatory developments in the jurisdictions where Plaintree operates; change in tax laws; political conditions and developments; intensifying competition from established competitors and new entrants in the free space optics (FSO) industry; technological change; currency value fluctuation and  general economic conditions worldwide; Plaintrees success in developing and introducing new products and services, expanding existing distribution channels and developing new distribution channels.  On April 1, 2008, Plaintree completed the acquisition (the Acquisition) of Hypernetics Limited (Hypernetics) and 4439112 Canada Inc., which through a wholly-owned subsidiary owned all of the share capital of Triodetic Building Products Inc. and other subsidiaries (the Triodetic Group of Companies) and immediately following the Acquisition Plaintree amalgamated (the Amalgamation) the businesses of each of Hypernetics and the Triodetic Group of Companies into Plaintree resulting in certain additional risk factors, including but not limited to business integration risk factors.  This list is not exhaustive of the factors that may affect any of Plaintrees forward-looking statements. Plaintree undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made, or to reflect the occurrence of unanticipated events, whether as a result of new information, future events or results otherwise except as required by law. Readers are cautioned not to put undue reliance on forward-looking statements. Readers should also carefully review the risks concerning the business of the Company and the industries in which it operates generally described elsewhere in this 20-F and in the other documents filed from time to time with Canadian securities regulatory authorities and the United States Securities and Exchange Commission.  All dollar amounts referred to herein, unless otherwise stated, are in Canadian dollars.



Reference to Company



The Acquisition was treated by Plaintree as a transaction between parties under common control and is accounted for under the continuity of interest method. Under the continuity of interest method, the 2010, 2009, 2008 and 2007 results are presented as if Plaintree, Hypernetics and Triodetic Group of Companies were combined companies at the commencement of fiscal 2007.  The financial results for fiscal 2006 are presented for Plaintree only (pre-amalgamation). In this 20-F, references to Company for the period up to and including March 31, 2010 refer to Plaintree Systems Inc. post Amalgamation unless otherwise noted.

Risk Factors

As of the date of this 20-F, the risk factors that are specific to the Company include those set out below.  The Company may face additional risks and uncertainties other than the factors set out below, including, risks and uncertainties that are unknown to the Company or risks and uncertainties that the Company now believes to be unimportant which could have a material adverse effect on the business of the Company.  If any of the following risks actually occur, the business, financial condition or results of operations of the Company could be negatively affected.

Limited Operating History. The Company has a limited operating history as a combined company with two years history of earnings. Prior to the Amalgamation, the Plaintree had limited success generating sufficient operating revenues to finance its day-to-day operations.

Limited Financial Resources. The Company has and likely will continue to have limited financial resources and has and continues to rely on related party financing. Additional financing may be required which, if available, may not be available on favorable terms or could serve to dilute existing equity. Lack of any necessary additional financing could impair the Companys future growth. Failure of the Company to obtain additional future financing could cause the Company to forfeit its interest in its products and reduce or terminate its operations. While the related parties have agreed not to demand the line of credit or the demand loan through at least August 2011, there is no assurance that they will delay beyond that.

Growth Related Risks.  The Company may be subject to growth related risks including capacity constraints and pressure on its internal systems and controls.  Any inability by the Company to deal with growth could have a material adverse impact on its business, operations and prospects.

Intellectual Property. The success of the Company will depend, in part, on the ability to protect its proprietary information relating to its wireless products, structured buildings and aviation products and related manufacturing equipment and to operate without infringing upon the proprietary rights of third parties. The products being developed by the Company are capable of being duplicated or improved upon by competitors and accordingly, the Company may be vulnerable to competitors who develop competing products, whether independently or as a result of acquiring access to the Companys proprietary products or trade secrets. If this occurs, then the Company may incur legal costs in actions to protect its proprietary interests or to defend itself in suits brought by others against the Company pertaining to such matters.

Laws and Regulations. The construction and aviation industry in Canada and in the United States is subject to various national, regional and local laws and regulations governing taxes, labor, safety, protection of the environment and other matters. Amendments to current laws and regulations governing the operations and activities of companies such as the Company, or more stringent implementation thereof, could have an adverse impact on the Company. The Company intends to distribute its products and services through distributors in North America and other countries and as a result foreign laws should be considered as potential risk.

Licenses and Permits. The operations and products of the Company may require licenses and permits from various governmental authorities. There is no assurance that the Company will be able to obtain all necessary licenses and permits that may be required to successfully carry out sales of its products in those jurisdictions requiring such licenses and permits.

Environmental Risks and Other Regulatory Requirements. The current or future operations of the Company, including development activities and commencement of production will likely require permits from various federal and local authorities in such operations and will be governed by laws and regulations governing development, production, taxes, labor standards, occupational health, and waste disposal, handling toxic substances, land use, environmental protection and other matters. There can be no assurance that all permits which the Company may require will be obtainable on reasonable terms or those laws and regulations would not have an adverse affect.

Conflicts of Interest. Some of the directors of the Company are or may become directors and/or shareholders of other companies, and situations may arise in which there may be potential conflicts of interests. Any decisions made by any director of the Company in respect of a situation where there is such a conflict of interest will be made in accordance with his or her duty to act honestly, in good faith and in the best interests of the Company, after having disclosed his or her interest to the Company, and after giving consideration to, among other matters, the Companys objectives, working capital requirements and its ability to adequately finance such new opportunities.

Fluctuations in the value of foreign currencies could result in currency exchange losses.  A portion of the Companys revenues and expenses will be denominated in United States dollars. Therefore, fluctuations in the Canadian dollar exchange rate will impact our results of operations and financial condition from period to period. In addition, such fluctuations affect the translation of the Companys results for purposes of its consolidated financial statements. The Companys currency hedging activities (if any) may not be successful.

Reliance Key Personnel/Employees.  The Companys success is largely dependent upon the performance of key employees and the Companys ability to hire and retain highly skilled and qualified personnel.  The Company will face competition for qualified personnel from numerous industry sources and there can be no assurance that it will be able to attract and retain qualified personnel on acceptable terms.  The loss of service of any key personnel could have a materially adverse effect on its operations or financial condition.

Management.  The Companys success is largely dependent on the performance of its management.  The loss of services of any of these persons could have a materially adverse effect on its business and prospects.  There is no assurance that the Company can maintain the services of its directors, officers or other qualified personnel required to operate its business.

Competition and Market Factors

The Companys Specialty Structures Division faces a number of competitors around the world for its construction business.  In the event that one of these competitors located in an area of the world with low labor and environmental costs becomes aggressive in worldwide marketing and pricing, this could have a detrimental effect on the sales of this division. Additionally, a large portion of this divisions sales are currently to mining and commercial construction companies. Continued declines in these markets will detrimentally affect sales.

The Companys Electronics Division experiences competition for its products in the aviation and optical wireless communication markets. Its sales closely mirror the fluctuations of these markets and the continuing struggles the commercial carriers are suffering may have a detrimental effect on this division's sales.

Liability

The Specialty Structures Division is a design authority for its buildings and structures. The failure or other complication of one of these products could result in a legal action that could have a detrimental effect on the Company.

The Electronics Division may occasionally be a design authority for its avionics products which may be used on commercial aircraft. The failure or other complication of one of these products, whether or not the Company is the design authority, could result in a legal action that could have a detrimental effect on the Company.

Overview



The Company has two primary operating business divisions: Electronics Division and Specialty Structures Division.



Electronics Division



The Companys Electronics Division has two main product lines, aerospace and optical wireless transmission links.



Aerospace



As a manufacturer and distributor of aerospace components for various applications including aircraft antiskid braking; aircraft avionics; solenoids; and permanent magnet alternators, the Company is certified to AS9100B, the highest international quality standard in the aerospace sector.



Optical Wireless



The Company designs, develops, manufactures, markets and supports infrared optical wireless transmission links. The Companys WAVEBRIDGE links send information (voice, video and data) on a beam of infrared light. These links act as a replacement for cable or fiber, thus avoiding the delay and expense of the planning and installation of wireline connections.  Simplicity of installation of the WAVEBRIDGE links ensures they can be up and running in a matter of hours thus avoiding costly network downtime.  These links are also an alternative to microwave or radio frequency (RF) systems and they require no licensing.  The high deployment densities of RF and microwave systems cause frequency interference and overlap problems that are not experienced by FSO systems.  Optical wireless systems can also carry a bigger payload than RF systems, making them a very attractive solution.



Specialty Structures Division



The Company is a pioneer in the development of an innovative mechanical jointing system to interconnect multi-axial tubular components. The system is widely used in architectural, commercial and industrial structures using steel, aluminum or stainless steel materials. The Company has developed covering systems to complement these applications. Some product offerings include commercial domes, barrel vaults, space frames, free form structures and solar support systems.



Methods of distribution and principal markets



Electronic Division



The Company markets its Optical Wireless Products world-wide through direct sales, VARs, distributors, VAIs and Internet management.  The Company reseller program has established close working relationships with a limited number of solution providers to serve as extended sales and support force in Canada, the United States and around the world.   The Company manufactures a wide range of components for the aerospace market including: wheel
speed transducers for aircraft antiskid, electromagnetic indicators for aircraft cockpit instrumentation and proximity sensors for general sensing on aircrafts.  The Company markets its products world-wide through direct sales, system integrators, distributors and repair centers.  The Company has developed a thirty-seven year relationship with its primary customer base located in the United States.  The Company has also taken advantage of many on-line market specific advertising services such as Inventory Listing Services and Stock-Market.

Specialty Structures Division



The Company markets its tubular structural products world-wide directly to architects and engineers and through sales agents.  Over the past 40 years, the Company has developed strong relationships with many of these architects and engineers which have resulted in new and repeat business.  The Company has many active sales agents around the globe and they share the Companys commitment to delivering quality and customer satisfaction.



Method of production of products



Electronics Division



The Companys manufacturing operations are located close to the Ottawa region in Arnprior, Ontario near a substantial community of high technology and aerospace companies.  The Companys manufacturing operations consist primarily of engineering, machine shop, production and quality control. The Company generally purchases raw materials and manufacturers a final product and performs full quality inspection before shipping to the customer. In some cases, parts are shipped to subcontractors for treatment under special processes or ordered to the Companys specifications. These parts are fully inspected by a designated quality inspector upon return to the Companys premise from the subcontractor.  The parts are packaged and shipped from the Companys manufacturing facility to the customer location.  The Company manages the sales accounts from the manufacturing plant in Arnprior through e-mail, teleconference and direct calling.



Specialty Structures Division



The Companys manufacturing operations are located close to the Ottawa region in Arnprior, Ontario.  The Companys manufacturing operations consist primarily of pre-forming galvanized steel, aluminum or stainless steel tubing, manufacturing cylinder hubs, base plates and other assembly products, pre-finishing inspection, quality control, final crating and shipping to the customers destination.  The Company generally purchases raw materials many of which are prepared to the Companys specifications. Most of the Companys subcontractors and finished good suppliers also have their offices in the Ottawa area.  These companies provide an infrastructure of services and a local pool of skilled workers and professionals.



Sources, pricing, component parts or finished products



Electronics Division



The Company currently purchases its components and materials from a vendor base of approximately 50 different suppliers Most of the components and materials are available from more than one supplier.  Certain components such as diodes and optical chip sets, however, are available from only a single source or from limited sources, some of which require order lead times of up to 20 weeks.  In general, the Company has been able to obtain adequate supplies of all components by scheduling orders over specified periods of time.  In order to avoid late shipments due to delays in the manufacturing process, the Companys policy is to maintain an inventory of components, materials and assembled products in quantities sufficient to meet approximately three months of expected sales.



Specialty Structures Division



The Company currently purchases its raw materials from a vendor base of approximately 25 different suppliers.  Most of the raw materials are available from more than one supplier.  Certain raw materials are available from only a single source or from limited sources, some of which require order lead times of up to 4 to 6 weeks.  In general, the Company has been able to obtain adequate supplies of all raw materials by scheduling orders over specified periods of time.  In order to avoid late shipments due to delays in the manufacturing process, the Companys policy
is to maintain an inventory of raw materials and assembled products in quantities sufficient to meet approximately three months of expected sales.  These suppliers are generally major manufacturers.

Importance, duration and effect on patents, software, subscription lists and trademarks



Electronics Division



The Company principally relies on copyright, trade secret and contract law to protect its proprietary optical wireless technologies.  It may be possible for a third party to copy or otherwise obtain and use the Companys products or technologies without authorization, or to develop similar technologies independently and there can be no assurance that such measures are adequate to protect the Companys proprietary technologies.  In addition, the Companys products may be licensed in foreign countries and the laws of such foreign countries may treat the protection of proprietary rights differently than, and may not protect the Companys proprietary rights to the same extent as do, the laws of Canada.  Although the Company appreciates the benefits of patent protection, it believes that the rapid pace of technological change in this industry makes patent protection less significant than factors such as the knowledge, ability and experience of the Companys employees, frequent product enhancements, and the timeliness and quality of support services provided by the Company. The Company also has registered trademarks in Canada and the United States. With respect to the aerospace products, the Company relies on strict product approvals and 38+ years of experience and product sales as a major competitive advantage.  When an integrator (Companys customer) is awarded a contract from Boeing, Airbus, Bombardier, etc. the specified products are locked into the design.    Other products are competitively positioned in the market.

Competitive conditions in the principal markets and geographic areas in which the Company operates, including an assessment of the Company's competitive position



Electronics Division



The competitors for the optical wireless products are companies that produce short-haul wireless connectivity products which include RF, microwave and FSO companies. FSO has significant advantages over radio-based systems for certain markets, defined by range, bandwidth, flexibility, ease of installation and environmental requirements. The competitors for the aerospace products are companies that manufacture wheel speed transducers/tachometers/sensors, aircraft cockpit instrumentation and proximity sensors for the aerospace market.  There are two known competitors in the wheel speed transducer market.  These competitors are located in the United States and France.  There is only one known competitor in the indicators business and one known competitor in the proximity sensor business, both located in the US.  The Company has been manufacturing products for many of its customers for over 38 years and is able to win new business and maintain existing accounts by offering a competitive high quality product to the market.



Specialty Structures Division



The competitors for the Structures Division Company include several international space-frame and dome specialists, but direct competition is typically against metal fabricators in each project location.  The Company prefers negotiated contracts and focuses on securing profitable business primarily through promoting to architects, engineers, designers and specifiers.

Applications for the Companys tubular structures can be served by other arrangements of bolted or welded structural steel (e.g., rolled and plate beams, columns, bar joists, trusses and fabrications) and also by alternative pre-engineered framing systems.



The international market is so large and dispersed that these companies would compete directly against the Company typically on industrial or architectural projects in and outside the United States.



Various metal space-frame systems exist outside of North America; however, the Company has only minimally encountered them in international proposals.



Each project poses a different set of requirements that could favor one supplier versus another.  The Company exhibits distinctive competence in all product categories and in many applications which contributes to its high order of new and repeat business success rate.



Human Resources



As at the date of this 20-F, the Companys total work force is approximately 60 persons. All management employees execute confidentiality agreements with the Company and assignments of intellectual property rights to the Company.  The Companys employees consist of both unionized and non-unionized employees.



Facilities



The Company operates out of two buildings located in Arnprior, Ontario, Canada with one having approximately 25,000 square feet and the other approximately 12,000 square feet.



Legal Proceedings



There currently are no known legal claims or proceedings against the Company or to which the Company is a party to.

The following discussion of the financial condition, changes in financial condition and results of operations of Plaintree for the years ended March 31, 2010, 2009, and 2008 should be read in conjunction with the audited consolidated financial statements and notes of Plaintree for the year ended March 31, 2010 (Fiscal 2010 Statements).  Historical results of operations, percentage relationships and any trends that may be inferred therefrom are not necessarily indicative of the operating results of any future period. All amounts are in Canadian dollars, unless otherwise stated, and in accordance with Canadian generally accepted accounting principles (Canadian GAAP). Canadian GAAP financial statements are reconciled to United States generally accepted accounting principles (US GAAP).



Overview



Located in Arnprior, Ontario, Plaintree historically developed and manufactured the WAVEBRIDGE series of free space optics (FSO) wireless links using Class 1, eye-safe light emitting diode  technology providing high-speed network connections for cable companies, internet service providers, traditional telcos, global system for mobile  or cellular operators, airports and campus networks.  Acting as a replacement for cable, fiber or radio frequency systems, the WAVEBRIDGE links offer broadband access with no spectrum interference problems, and same day installation for rapid network deployment.



On April 1, 2008, the Company completed an acquisition (the Acquisition) of all of the issued and outstanding share capital of (i) Hypernetics Limited (Hypernetics); and (ii) 4439112 Canada Inc. which owned all of the share capital of Triodetic Holdings Inc. and other subsidiaries including Triodetic Building Products Inc. (the Triodetic Group of Companies). Following the Acquisition, Hypernetics and 4439112 Canada Inc., including 4439112 Canada Inc.s wholly-owned Canadian incorporated subsidiaries and excluding its US incorporated subsidiary, were amalgamated into Plaintree.  The businesses of Hypernetics and the Triodetic Group of Companies are now being operated as separate divisions of Plaintree. See Related Party Transactions  Acquisition of Hypernetics and the Triodetic Group of Companies for additional information.  Unless otherwise indicated, a reference to Plaintree or Company in this document shall be a reference to the amalgamated Plaintree.



Hypernetics was established in 1972 and was a manufacturer of avionic components for various applications including aircraft antiskid braking, aircraft instrument indicators, solenoids, high purity valves and permanent magnet alternators.  The legacy Hypernetics and Plaintree FSO businesses are now managed as the Electronics Division of Plaintree.



The Triodetic Group of Companies had over 40 years of experience as a design/build manufacturer of steel, aluminum and stainless steel specialty structures such as commercial domes, free form structures, barrel vaults, space frames and industrial dome coverings.  The legacy Triodetic business is managed as the Specialty Structures division of Plaintree.



The total purchase price for both Hypernetics and the Triodetics Group of Companies was paid by the Company by the combination of $1,500,000 cash, the issuance of 3,500,000 common shares (35,000,000 pre-consolidation) of the Company and the issuance of 18,325 Class A preferred shares of the Company (having a redemption value of $18,325,000).



Concurrent with the Acquisition, Targa Group Inc., a company controlled by William David Watson II and Nora Watson and Plaintrees largest shareholder, provided a credit facility of up to $2.8 million to Plaintree, consisting of (a) a demand loan of $1.8 million; and (b) a revolving $1 million credit line.  All amounts advanced to Plaintree are payable on demand and bear interest at a rate per annum equal to 2% above the prime lending rate of the Companys banker as from time to time determined.  The credit facility is secured by a security interest granted over the assets of Plaintree



In addition to the Acquisition and subsequent to its fiscal 2008 year end on April 1, 2008, Plaintree also:



(a)

created Class A preferred shares, which were issued as part of the consideration in the Acquisition. The Class A Preferred Shares are non-voting, have a redemption value of $1,000 per share, are entitled to cumulative dividends of 8% per year, are redeemable at any time at the option of Plaintree and have a liquidation preference
equal to their redemption value plus any cumulative dividends accrued but not paid in priority to the common shares;

(b)

consolidated the outstanding common shares of the Company on a 10 pre-consolidation shares for 1 post-consolidation share basis; and



(c)

deleted an old class of preferred shares no longer being used by the Company.

Accounting for convertible debentures



Under U.S. GAAP, the convertible debentures issued in April and June 2005 would not be bifurcated into their debt and equity components.  Accordingly, under U.S. GAAP, the due to related parties - convertible debentures would increase by $NIL (2009 - $NIL; 2008 - $NIL); accretion of debt discount, operating expenses, net income and shareholders' equity (deficiency) would decrease by $NIL (2009 - $NIL; 2008 - $7,384); and equity component of convertible debentures would decrease by $98,061 (2009 - $98,061; 2008 - $98,061).

Total product revenue for fiscal 2010 was $9,087,383 compared to $21,247,270 in fiscal 2009 and $13,848,507 in fiscal 2008.  Product revenue decreased in fiscal 2010 from levels seen in fiscals 2009 and 2008 due to the global economic downturn.



Plaintree has two diversified business divisions: Specialty Structures and Electronics.



Plaintrees Specialty Structures Division saw its first slowdowns occur in the first quarter of fiscal 2010. The world wide economic crisis continued to detrimentally affect this division's revenues throughout the 2nd and 3rd quarters. The Company saw increased activity in the 4th quarter of fiscal 2010 and expects that the Specialty Structure sales will increase in fiscal 2011.



Plaintree's Electronics Division derives most of its revenues from products installed on commercial aircraft and in particular, business jets. This market segment was hit very hard during the 2010 fiscal year and it is expected that this market will remain slower than usual through the first half of 2011.



Gross Margin



Total gross margin from management services revenue, from related parties, and product revenue for fiscal 2010 was $2,878,267 or 31.3% compared to $8,635,287 or 40.4% in fiscal 2009 and $5,349,375 or 38.6% in fiscal 2008. The gross margin for 2010 consists of a margin on management services to related parties of $75,456 (2009 - $111,167; 2008 - $nil) or 72.9% (2009  72.9%; 2008  0%) of management services revenue and a margin on product and management services revenue of $2,878,267 (2009 - $8,635,287; 2008 - $5,349,375), or 30.8% (2009  40.1%; 2008  38.6%) of sales. The gross margin on management services revenue which consists of revenues earned less direct employee salaries and benefits has remained consistent and is not expected to change significantly.



Gross margins related to product sales, not including inventory write-offs, in the fiscal 2008-2010 periods have been relatively constant around 40%. However, the margins have been reduced by additional inventory write-offs of $701,634, $382,790 and $121,108 incurred in each of fiscal 2010, 2009 and 2008.



Operating Expenses



Sales and marketing expenses



Sales and marketing expenses were $536,286, $915,002 and $1,133,251 for fiscal 2010, 2009 and 2008, respectively.  These expenses consisted primarily of personnel and related costs associated with the Companys sales and marketing departments, which include sales commissions, advertising, travel, trade shows and other promotional activities.



The fluctuations in sales and marketing expenses mainly relate to the cost of travel, commissions and advertising associated with the projects the company participated in during the period.  Some sales and marketing functions were consolidated during fiscal 2010 achieving cost reductions.



Finance and administration expenses



Finance and administrative expenses were $1,288,818, $1,610,596 and $1,651,325 in fiscal 2010, 2009 and 2008, respectively.  Finance and administration expenses consist primarily of costs associated with managing the Companys finances, which included financial staff, legal and audit activities.



Finance and administrative expenses were higher during fiscal 2009 and 2008 as the Company had additional auditing and due diligence requirements associated with the Acquisition and subsequent amalgamation transaction.

Research and development expenses



Research and development expenses were $1,451,471, $1,553,354, $1,687,657 in fiscal 2010, 2009 and 2008, respectively. Research and development expenditures consist primarily of development engineering and personnel expenses.



Interest expense



Interest expense consists of interest incurred on bank and related party debt. Interest expenses were $129,553, $228,489 and $481,470 in fiscal 2010, 2009 and 2008, respectively. Interest expense decreased in 2010 due to the repayment of an interest bearing related party debt and a decrease in the prime lending rate of interest charged by the Companys banker. The majority of the Companys debt accrues interest at variable rates based on the Companys bank prime lending rate of interest.



Gain on foreign exchange



The Company reported a loss on foreign exchange of $694,718 in fiscal 2010, a gain on foreign exchange of $417,667 in fiscal 2009 and loss of $133,535 for fiscal 2008. The gain/loss on foreign exchange represents the gain/loss, realized or unrealized, of transactions and year end foreign balances that are completed in currencies other than the Companys reporting currency.  During the fiscal year ended March 31, 2010, the value of the US dollar decreased in comparison to the Canadian dollar by approximately 25 % from the start of the year resulting in a loss on foreign exchange.



Accretion



Accretion expenses consist of amortization of the discount on the debt portion of convertible debentures.



Other income (loss)



Other income (loss) included a loss of $17,343 and $1,022, during fiscals 2010 and 2009 and a gain of $210,565 in fiscal 2008 resulting from the sale of surplus Company assets during these periods.



Investments held by the Company resulted in a loss of $nil in fiscal 2010, $6,658 in fiscal 2009, a gain of $55,117 in fiscal 2008.



Partnership income, other partnership related expenses and Bank loan interest



During the year ended March 31, 2008, a total of $2,000,000 of distributions was received from the Partnership following which Plaintrees investment in the Partnership was reduced to zero and the remaining $2,000,000 outstanding on the loan was satisfied through such distributions. In fiscal 2008, the Company recorded Partnership income allocations of $308,415 (2007 - $516,577).  Also recorded was bank loan interest expense of $8,415 (2007 - $214,994) and other Partnership related expenses of $nil (2007 - $59,677). In fiscal 2008, the Company ceased to be a partner and will receive no further income and incur no further expenses related to the Partnership. See Buhler Partnership Investment for further information.



Net Income (Loss)



The net loss for fiscal 2010 was $1,293,501 compared to net income for fiscal 2009 and fiscal 2008 of $4,844,499 and $721,835 respectively.

After the effects of the world economic decline during most of fiscal 2010, the Company has seen all of its markets rebound in the first quarter of fiscal 2011. Although contracts have not yet reached levels experienced in the 2009 fiscal year, the Company does expect these same volumes to be better than fiscal 2010 throughout fiscal 2011. Providing that the world economies do not slip into double dip recession, the Company is poised for a better year than fiscal 2010.



Fourth quarter of fiscal 2010



During the fourth quarter of fiscal 2010, revenue was approximately $3.4 M and the net loss was approximately $240,000.  Income (loss) from operations and net income (loss) for the each of the quarters in fiscal 2010 varied primarily due to the size, percentage completion and complexity of the projects entered into by the Specialty Structures division. Plaintree saw a return of customer inquiries and orders particularly for the Specialty Steel division during the fourth quarter of 2010.



Outlook



Fiscal 2010 concluded in a loss of approximately $1.3 million which included a loss on exchange of $695,000 and inventory write-down of $702,000. During fiscal 2010 the Company experienced delays in projects and in some cases cancellations of orders. Plaintrees specialty structures Division saw its first slowdowns occur in the first quarter of 2010. The world wide economic crisis continued to detrimentally affect this division's revenues throughout the 2nd and 3rd quarters. However, in the 4th quarter increased order activity was visible. The Company expects to see a moderate increase in sales in early 2011. Plaintree's electronics division derives most of its revenues from products installed on commercial aircraft and in particular, business jets. This market segment was hit very hard during the 2010 year and it is expected that this market will remain slower than usual through the first half of 2011.



As described in the Overview section of this MD&A, the Company completed the Acquisition of Hypernetics and the Triodetic Group of Companies on April 1, 2008.



The total purchase price for both Hypernetics and the Triodetic Group of Companies was paid by the Company by the combination of $1,500,000 cash; the issuance of 3,500,000 common shares (35,000,000 pre-consolidation) and 18,325 Class A preferred shares of the Company.  Following the Acquisition, Hypernetics and the Triodetic Group
of Companies, with the exception of a US incorporated subsidiary, were amalgamated into
Plaintree.  Following the completion of the amalgamation, the businesses of Hypernetics and the Triodetic Group of Companies have been operated as separate divisions of
Plaintree.

Facilities

As a result of the amalgamation, the Company obtained facilities previously owned by Hypernetics Ltd consisting of 12,000 square feet and by the Triodetic Group of Companies consisting of 18,000 square feet of plant and office space, both located in Arnprior, Ontario. In addition, the Company has completed the construction of additional plant and office space at its facilities in Arnprior, Ontario, providing another 7,000 square feet.



SIGNIFICANT ACCOUNTING POLICIES



The consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles ("Canadian GAAP") and include the following significant accounting policies:



Basis of presentation



The consolidated financial statements include the accounts of Plaintree, Hypernetics and the Triodetic Group of Companies and its wholly-owned subsidiaries.  All significant intercompany balances and transactions have been eliminated on consolidation.



Inventories



Inventories are valued using a weighted average cost formula and are stated at the lower of cost and net realizable value.  Costs, including an appropriate portion of fixed and variable overhead expenses, are assigned to inventories held by the method most appropriate to the particular class of inventory.  Net realizable value represents the estimated selling price for inventories less all estimated costs of completion and costs necessary to make the sale.



Property, plant and equipment and intangible assets



Property, plant and equipment and intangible assets are stated at cost.  Amortization is provided over the estimated useful lives of the assets using the straight-line method as follows:



Property, plant and equipment:



Building

20 years

Building improvements

10 years

Factory equipment

10 years

Computer equipment

The Company's policy is to review all long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount as an asset may not be recoverable.  If events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, the Company will estimate the future cash flows expected to result from the use of the assets and their eventual disposition and record an impairment of the assets if required.



Revenue recognition



Revenue from product sales is recorded on shipment when all significant contractual obligations have been satisfied provided evidence of an arrangement exists, the price to the customer is fixed and determinable and collection is probable.



Revenue on fixed-price contracts is recognized based on the estimated percentage of completion of services rendered that reflects the extent of work accomplished.  Management estimates the percentage-of-completion by reference to measures of performance that are reasonably determinable and are directly related to the activities critical to completion of the contract.  The Company uses this method of revenue recognition as projected contract revenue and costs may reasonably be estimated based on the Companys business practices, methods and historical experience.  This method requires estimates of costs and profits over the entire term of the contract.  Management regularly reviews underlying estimates of project profitability; revisions to estimates are reflected in the statement of income in the period in which the facts that give rise to the revision become known.  Provisions for estimated losses, if any, are recognized in the period in which the loss is determined.  Contract losses are measured as the amount by which the estimated costs of the contract exceed the estimated total revenue from the contract.



Progress billings are recorded as deferred revenue to the extent that the billings exceed revenue recognized to date.  Unbilled revenue is recorded to the extent that revenue has been recognized, but not yet billed to the customer.



In addition, a provision for potential warranty claims is recorded at the time of sale, based on warranty terms and prior claims experience.  Extended warranty contracts are sold separately from the product and the associated revenue is recognized over the term of the agreement.



Foreign currency translation



Monetary assets and liabilities, which are denominated in currencies foreign to the local currency of the operation, are translated to the local currency at fiscal year-end exchange rates, and transactions included in the statements of operations are translated at rates prevailing during the fiscal year.  Exchange gains and losses resulting from the translation of these amounts are included in the statement of operations.



The accounts of the Company's wholly-owned U.S. subsidiary, which is considered to be an integrated foreign operation, has been translated into Canadian dollars using the temporal method of foreign currency translation.  Under this method, monetary assets and liabilities are translated at the exchange rate in effect at the balance sheet date.  Non-monetary assets and liabilities are translated at historical rates.  Revenues and expenses are translated at average rates for the year.  Transaction gains or losses are included in income.



Stock option plans



The Company has a stock-based compensation plan.  The Company uses the fair value based method of accounting to record stock-based payments to employees and non-employees.  Under the fair value based method, compensation cost for both employees and non-employees is measured at fair value at the date of grant and is expensed over the awards vesting period.  The cost of stock-based payments that are fully vested and non-forfeitable at the grant date is measured and recognized at that date.

Investment tax credits



Investment tax credits are recorded as a reduction of the related expense or cost of the asset acquired.  The benefits are recognized when the Company has complied with the terms and conditions of the approved grant program or applicable tax legislation.



Research and development expenditures



Current research costs are expensed as incurred.  Expenditures for research and development equipment, net of related investment tax credits, are capitalized.



Development costs are deferred and amortized when the criteria for deferral under Canadian GAAP are met, or otherwise, are expensed as incurred.  To date, no such costs have been capitalized.



Use of accounting estimates



The preparation of financial statements in conformity with Canadian GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods presented.  Significant management estimates include percentage complete for revenue recognition, unbilled revenues, deferred revenues and allowance for doubtful accounts, useful lives of property, plant and equipment and intangible assets, inventory obsolescence, stock-based compensation, accrued liabilities, income tax valuation allowance and bifurcation of convertible debentures.  Actual results could differ from these estimates.



Income taxes



The Companys future income tax assets and liabilities are recognized for the future tax consequences attributable to tax loss carryforwards and to differences between the financial statement carrying amounts of existing assets and liabilities, and their respective tax bases.  Future income tax assets and liabilities are measured using enacted or substantively enacted rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed or be settled to the extent that such assets are more likely than not to be realized.  The effect on future income tax assets and liabilities of a change in tax rates is recognized in income in the period of enactment or substantive enactment.  Future income tax assets are recognized to the extent it is more likely than not to be realized.



Earnings per share



Earnings per share has been calculated on the basis of net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the year.  Income attributable to common shareholders is equal to net income less the dividends accumulated on the preferred shares.  Diluted earnings per common share is calculated by dividing the applicable net income attributable to common shareholders by the sum of the weighted average number of common shares outstanding and all additional common shares that would have been outstanding if potentially dilutive common shares had been issued during the period.  The Company uses the treasury stock method in determining the denominator for earnings per share.  Under this method it is assumed that the proceeds from the exercise of options are used to repurchase common shares at the weighted average market price of the shares for the period.



Financial instruments



Financial assets and financial liabilities are initially recognized at fair value and their subsequent measurement is dependent on their classification as described below.  Their classification depends on the purpose, for which the financial instruments were acquired or issued, their characteristics and the Companys designation of such instruments.  Settlement date accounting is used.

23





Held-for-trading



Held-for-trading financial assets are financial assets typically acquired for resale prior to maturity or that are designated as held-for-trading.  They are measured at fair value at the balance sheets date.  Fair value fluctuations including interest earned, interest accrued, gains and losses realized on disposal and unrealized gains and losses are included in other income.



Financial liabilities designated as held-for-trading are those non-derivative financial liabilities that the Company elects to designate on initial recognition as instruments that it will measure at fair value through other interest expense.  These are accounted for in the same manner as held-for-trading assets.  The Company has not designated any non-derivative financial liabilities as held-for-trading.





Held-to-maturity



Held-to-maturity financial assets are non-derivative financial assets with fixed or determinable payments and a fixed maturity, other than loans and receivables, that an entity has the positive intention and ability to hold to maturity.  These financial assets are measured at amortized cost using the effective interest rate method.



Available-for-sale



Available-for-sale financial assets are those non-derivative financial assets that are designated as available-for-sale, or that are not classified as loans and receivables, held-to-maturity or held-for-trading.  Except as mentioned below, available-for-sale financial assets are carried at fair value with unrealized gains and losses included in accumulated other comprehensive income until realized when the cumulative gain or loss is transferred to other income.



Available-for-sale financial assets that do not have quoted market prices in an active market are recorded at cost.



Interest on interest-bearing available-for-sale financial assets is calculated using the effective interest rate method.



Loans and receivables



Loans and receivables are accounted for at amortized cost using the effective interest rate method.



Other liabilities



Other liabilities are recorded at amortized cost using the effective interest rate method and include all financial liabilities, other than derivative instruments.



Transaction costs



Transaction costs related to held-for-trading financial assets are expensed as incurred. Transaction costs related to available-for-sale financial assets, held-to-maturity financial assets, other liabilities and loans and receivables are netted against the carrying value of the asset or liability and are then recognized over the expected life of the instrument using the effective interest rate method.



The Company has made the following classifications:



Cash is required to be classified as held-for-trading and is measured at fair value with changes in fair value recorded in net income.  The carrying amount approximates fair value.



Trade accounts receivable and unbilled receivables are required to be classified as loans and receivables and accounts payable and accrued liabilities are required to be classified as other financial liabilities and are measured at amortized costs with interest accretion recorded in net income.  Due to the short-term nature of these assets and liabilities, the carrying amounts approximate fair value.

24





All loans, bank loans, bonds and debentures or similar debt are measured at amortized cost with interest accretion recorded in net income.



New accounting policies



Goodwill and intangible assets



In February 2008, the Canadian Institute of Chartered Accountants ("CICA") issued Section 3064, Goodwill and Intangible Assets, replacing Section 3062, Goodwill and Other Intangible Assetsand Section 3450, Research and Development Costs.  Various changes have been made to other sections of the CICA Handbook for consistency purposes.  The new Section is applicable to the Company's fiscal year ended March 31, 2010. The adoption of this standard required the Company to retroactively reclassify its licensed computer software assets on its balance sheet from property, plant and equipment to intangible assets. The net book value of licensed computer software reclassified as of March 31, 2009 was $8,700.





In January 2009, the CICA issued EIC-173, Credit Risk and the Fair Value of Financial Assets and Financial Liabilities, which clarifies that the Company's own credit risk and the credit risk of counterparties should be taken into account in determining the fair value of financial assets and financial liabilities, including derivatives.  EIC-173 is to be applied retrospectively without restatement of prior periods to all financial assets and liabilities measured at fair value for periods ending on or after the date of issuance of this Abstract.  The Company concluded that this standard had no material impact on its consolidated financial statements upon adoption during the year.



In August 2009, the CICA amended Handbook Section 3855, Financial Instruments - Recognition and Measurement, which adds guidance concerning the assessment of embedded derivatives upon reclassification of a financial asset of the held-for-trading category.  In addition, this Section has been amended to: change the categories into which a debt instrument is required or permitted to be reclassified and change the impairment model for held-to-maturity financial assets to the incurred credit loss model of impaired loans; and require reversal of previously recognized impairment losses on available-for-sale financial assets in specified circumstances.  These amendments apply to annual financial statements relating to fiscal years beginning on or after November 1, 2008.  The adoption of this new Section did not have a material impact on the Company's consolidated financial statements.



In June 2009, the CICA amended CICA Handbook Section 3862, Financial Instruments - Disclosure, which enhances disclosures about fair value measurements, including the relative reliability of the inputs used in those measurements and expanded requirements regarding liquidity risk disclosure.  The new guidance does not change the financial instruments measurement requirements of Section 3855, but amends the disclosure requirements, which are as a result of changes made to International Financial Reporting Standard (IFRS) 7.  The guidance applies to financial instruments measured at fair value on the balance sheet and establishes a hierarchy for each financial instrument on an individual basis.  These amendments are effective for annual financial statements relating to fiscal years ending after September 30, 2009. The adoption of this new Section did not have a material impact on the Company's consolidated financial statements.



Changes in accounting policy under US GAAP



In September 2006, the FASB issued FAS No. 157,Fair Value Measurements("FAS 157"). FAS 157 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements.  In February 2008, the FASB amended FAS 157 by issuing FSP 157-1,Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13("FSP 157-1"). In February 2008, the FASB also issued FSP 157-2,Effective Date of FASB Statement No. 157("FSP 157-2").  FSP 157-1 amends FAS 157 to exclude fair value requirements on leases.  FSP 157-2 delays the effective date of FAS 157 for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to Fiscal Years beginning after November 15, 2008.  The Company adopted certain provisions of FAS 157, effective April 1, 2008. The Company is currently evaluating the effect that the adoption of the provisions deferred by FSP 157-1 and FSP 157-2 will have on its consolidated financial statements.

In June 2007, the FASB ratified the consensus reached by the Emerging Issues Task Force on Issue No. 07-3, Accounting for Advance Payments for Goods or Services Received for Use in Future Research and Development Activities ("EITF 07-3"). EITF 07-3 indicates that non-refundable advance payments for future R&D activities should be deferred and capitalized until the goods have been delivered (assuming the goods have no alternative future use) or the related services have been performed. EITF 07-3 also indicates that companies should assess deferred R&D costs for recoverability.  Companies are required to adopt EITF 07-3 for new contracts entered into in Fiscal Years beginning after December 15, 2007.  Earlier application is not permitted. The Company adopted EITF 07-3 in the first quarter of Fiscal 2009.  The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In December 2007, the FASB revised SFAS No. 141R, Business Combinations.  This revision establishes principles and requirements for how the acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquire, recognizes and measure the goodwill acquired in the business combination or a gain from a bargain purchase, and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination.  This Statement is required to be adopted by the Company for business combinations for which the acquisition date is on or after the beginning of the first fiscal year beginning on or after December 15, 2008. The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In December 2007, the FASB issued SFAS No. 160, Non-controlling Interests in Consolidated Financial Statements - an Amendment of ARB No. 51.  SFAS No. 160 establishes accounting and reporting standards for non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary.  SFAS No. 160 is effective for fiscal years beginning after December 15, 2008.  The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In May 2008, FASB issued FASB Staff Position Accounting Principles Board 14-1 ("APB 14-1"), which revises the accounting treatment for convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement.  APB 14-1 requires the issuer to separately account for the liability and equity components of convertible debt instruments. The value assigned to the liability component would be the estimated fair value, as of the date of issuance, of similar debt without the conversion option, but including any other embedded features.  The difference between the proceeds of the debt and the value allocated to the liability component would be recorded in equity.  The standard is effective for periods beginning on or after December 15, 2008, and is to be applied retrospectively.    The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In May 2008, the FASB issued FASB Statement No. 162, The Hierarchy of Generally Accepted Accounting Principles ("FAS 162"), which identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of non-governmental entities that are presented in conformity with U.S. GAAP.  FAS 162 is effective 60 days following the Securities Exchange Commission approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in Conformity with GAAP.  The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In November 2008, FASB Task Force clarified the accounting for certain transactions and impairment considerations involving equity method investments.  Topics related to equity method investments include the initial carrying value of an equity method investment, impairment assessment of an investees intangibles and an equity investees issuance of shares. EITF 08-6 is effective for fiscal years beginning on or after December 15, 2008.  The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In April 2009, the FASB issued an amendment to the Financial Instruments Topic of the FASB ASC, which requires disclosures about fair value of financial instruments in interim as well as annual financial statements.  This amended Topic is effective for periods ending after June 15, 2009. The Company adopted this amended Topic in the first quarter of Fiscal 2010.  The adoption of this Topic did not have a material impact on the Companys financial position or results of operations.



In April 2009, FASB issued FSP No. 141(R)-1, Accounting for Assets Acquired and Liabilities Assumed in a Business Combination that Arise from Contingencies.  This FSP amends and clarifies FASB Statement No. 141 (revised 2007), Business Combinations, to address application issues raised by preparers, auditors, and members of the legal profession on initial recognition and measurement, subsequent measurement and accounting, and
disclosure of assets and liabilities arising from contingencies in a business combination.  The adoption of this standard did not have a material impact on the Companys consolidated financial statements.

In May 2009, the FASB issued the Subsequent Events Topic of the FASB ASC.  This Topic establishes general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The Topic sets forth (1) the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements; (2) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and (3) the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. In February 2010, the FASB issued ASU, 2010-09, to provide amendments to the Subsequent Events Topic of the FASB ASC.  These amendments clarified certain disclosures previously required by the Topic. This Topic is effective for interim or annual periods ending after June 15, 2009.  The Company adopted this Topic in the first quarter of Fiscal 2010, and the amendments contained in the ASU in the fourth quarter of Fiscal 2010.  The adoption of the Topic and its amendments did not have a material impact on the Companys financial position or results of operations.



In June 2009, the FASB issued SFAS 166 Accounting for Transfers of Financial Assets- an amendment of FASB Statement No. 140. SFAS 166 requires that a transferor recognize and initially measure at fair value all assets obtained (including a transferor's beneficial interest) and liabilities incurred as a result of a transfer of financial assets accounted for as a sale. SFAS 166 must be applied as of the beginning of each reporting entity's first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period and for interim and annual reporting periods thereafter.  Earlier application is prohibited.  This Statement must be applied to transfers occurring on or after the effective date. The adoption of this standard did not have a material impact on the Companys consolidated financial statements.



In June 2009, the FASB issued FASB Statement No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles - a Replacement of FASB Statement No. 162 (the "Codification", or "FASB ASC"). The FASB ASC will be the single source of authoritative non-governmental U.S. GAAP. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants.  The FASB ASC is effective for interim and annual periods ending after September 15, 2009.  All pre-Codification GAAP are superseded as described in FASB Statement No. 168. All other accounting literature not included in the Codification is non-authoritative. The Company adopted the Codification in the second quarter of Fiscal 2010. The Codification did not have a material impact on the Companys consolidated financial statements. The Company has updated references to the FASB ASC, as appropriate.



Future accounting changes



International Financial Reporting Standards



The Canadian Accounting Standards Board has confirmed that the use of IFRS will be required commencing 2011 for publicly accountable, profit oriented enterprises.  IFRS will be replacing current Canadian GAAP followed by the Company.  The Company will be required to begin reporting under IFRS for its first fiscal year beginning after January 1, 2011 and will be required to provide information that conforms to IFRS for the comparative periods presented.  Accordingly, the Company expects that its first interim financial statements presented in accordance with IFRS will be for the three-month period ended June 30, 2011, and its first annual financial statements presented in accordance with IFRS will be for the year ended March 31, 2012, which will include comparative data for the prior year.



The Company is in the process of commencing its transition plan that is being overseen by the Companys Chief Financial Officer. The transition plan consists primarily of three phases: assessment, planning and implementation. The Company will be working on the assessment phase of its conversion program, which includes a detailed review of the current differences between Canadian GAAP and IFRS and impact assessment on systems, procedures and financial statements. The Company will address the design, planning, solution development and implementation of the conversion in the current year.  The Company expects to make changes to processes and system before the 2012 fiscal year, in time to enable the Company to record transactions under IFRS. Reporting is done to the Audit Committee of the Companys Board of Directors on a regular basis. The Company will provide specialized training to internal resources as required.

Future accounting changes under U.S. GAAP



In June 2009, the FASB issued SFAS 167 Amendments to FASB Interpretation No. 46(R). SFAS 167 requires an additional reconsideration event when determining whether an entity is a variable interest entity when any changes in facts and circumstances occur such that the holders of the equity investment at risk, as a group, lose the power from voting rights or similar rights of those investments to direct the activities of the entity that most significantly impact the entity's economic performance.  It also requires ongoing assessments of whether an enterprise is the primary beneficiary of a variable interest entity. SFAS 167 shall be effective as of the beginning of each reporting entity's first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. Earlier application is prohibited.  The Company is currently evaluating the impact of the adoption of the standard on the Company's consolidated financial statements.



In October 2009, the FASB issued ASU, 2009-13, to address the accounting for multiple-deliverable arrangements to enable vendors to account for products or services (deliverables) separately rather than as a combined unit. This ASU provides amendments to the criteria in the Revenue Recognition - Multiple-Element Arrangements Subtopic of the FASB ASC.  As a result of those amendments, multiple-deliverable arrangements will be separated in more circumstances than under existing U.S. GAAP. The amendments in this ASU will be effective prospectively for revenue arrangements entered into or materially modified in Fiscal Years beginning on or after June 15, 2010.  The Company is required to adopt this ASU in Fiscal 2012.  The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements.



In October 2009, the FASB issued Accounting Standards Update ("ASU"), 2009-14, to address concerns raised by constituents relating to the accounting for revenue arrangements that contain tangible products and software.  The amendments in this ASU change the accounting model for revenue arrangements that include both tangible products and software elements.  Tangible products containing software components and non-software components that function together to deliver the tangible products essential functionality will no longer be within the scope of guidance in the Software - Revenue Recognition Subtopic of the FASB ASC.  The amendments in this ASU will be effective prospectively for revenue arrangements entered into or materially modified in Fiscal Years beginning on or after June 15, 2010.  The Company is required to adopt this ASU in Fiscal 2012.  The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements.



Future accounting changes under Canadian GAAP



Consolidated financial statements



In January 2009, the CICA issued Handbook Sections 1601, Consolidated Financial Statements, and 1602, Non-Controlling Interests, which will replace the former Section 1600, Consolidated Financial Statements.  These new Sections are effective for interim and annual consolidated statements for fiscal years beginning on or after January 1, 2011 but with earlier adoption permitted and provide the Canadian equivalent to International Accounting Standard (IAS) 27, Consolidated and Separate Financial Statements.  The new standards are not expected to have a material effect on the Companys consolidated financial statements.

Business Combinations



In January 2009, the CICA issued Handbook Section 1582, Business Combinations, which will replace the former Section 1581, Business Combinations.  The new Section is effective for acquisitions in fiscal years beginning on or after January 1, 2011 but with earlier adoption permitted and provides the Canadian equivalent to IFRS 3, Business Combinations.  The new standard is not expected to have a material effect on the Companys consolidated financial statements.



EIC-175



In December 2009, the CICA issued EIC-175, Multiple Deliverables Revenue Arrangements.  The accounting changes summarized in EIC-175 are effective for fiscal years beginning on or after January 1, 2011, with early adoption permitted.  Adoption may either be on a prospective basis or by retrospective application.  If the Abstract is adopted early, in a reporting period that is not the first reporting period in the entity's fiscal year, it must be applied retroactively from the beginning of the Company's fiscal period of adoption.  The Company is currently assessing
the future impact of these amendments on its consolidated financial statements and has not yet determined the timing and method of its adoption

Cash



As at March 31, 2010, the Company held $1,401,678 in cash, a decrease of $50,051 from March 31, 2009 primarily due to repayment of debt.





Working Capital



Working capital represents current assets less current liabilities.  As at March 31, 2010, the Company had positive working capital of $3,736,184 compared to a working capital of $5,940,231 at March 31, 2009.  The decrease in working capital was primarily a reduction in accounts receivable and inventory resulting from the lower sales activity and Company efforts to reduce its levels of inventory. The Company is subject to various covenants on the long-term debt (including debt to tangible net worth, current assets to current liabilities, capital and debt service ratios). The Company is in breach of the debt service ratio covenant to which the bank has provided a waiver letter
waiving payment to April 1, 2011, with respect to these breaches; therefore the loans to the bank are not classified as a current liability.

Cash provided by Operating activities

Cash provided by operating activities for fiscal 2010 was $1,651,673 representing a decrease of $1,601,378 from $3,253,051 in fiscal 2009. The decreased cash provided by operating activities mainly relates to the net loss incurred in fiscal 2010 but was offset by the reduction in working capital assets.



Cash used in Investing activities

Cash used in investing activities for fiscal 2010 of $231,339 relates mainly to the purchase of fixed assets. This amount compares to net use of $2,408,450 in fiscal 2009 consisting of the purchase of assets of $908,450 including the construction of additional plant and office space, providing another 7,000 square feet and a $1,500,000 one time payment affecting the continuity of interests that occurred upon the acquisition of Hypernetics and Triodetic Group of Companies.



Cash used in Financing activities

Cash used in financing activities for fiscal 2010 was $1,470,385 compared to cash used in financing activities for fiscal 2009 of $1,162,017.  Cash used in financing activities for fiscal 2010 relates mostly to the repayment of amounts under the related party line of credit and demand loan and dividend payments to the Class A preferred shareholders. Cash used in financing activities during fiscal 2009 consisted of repayments to related parties. The Company intends to further reduce its amounts due to related parties as it generates cash from operations.

Compensation



Compensation Discussion and Analysis



Compensation, Philosophy and Objectives



The Company does not have a formal compensation program. On advice from time to time given by the Compensation and Corporate Governance Committee, the board of directors of the Company (the Board or the Board of Directors) meets to discuss and determine compensation for the President and Chief Executive Officer, without reference to formal objectives, criteria or analysis.  The President and Chief Executive Officer of the Company is responsible for determining the compensation arrangements for the balance of the employees, including senior management, of the Company.  The general objectives of the Companys compensation strategy are to (a) compensate management in a manner that encourages and rewards a high level of performance and outstanding results with a view to increasing long term shareholder value; (b) align managements interests with the long term interest of shareholders; and (c) to ensure that the total compensation package is designed in a manner that takes into account the constraints that the Company is under by virtue of the fact that its is a venture issuer without a long history of earnings.



The Board, as a whole, ensures that the total compensation paid to the President and Chief Executive Officer, is fair and reasonable. The Board relies on the experience of Company management and its members as officers and directors of other companies in assessing compensation levels.  The President and Chief Executive Officer of the Company is responsible for ensuring that total compensation paid to the other employees, including senior management, of the Company is fair and reasonable.



Analysis of Elements



Certain of the Named Executive Officers have received bonus payments during fiscal 2010 while others have deferred a significant portion of their salary. Reference is made to the Summary Compensation Table set out below.



The Company considers the granting of incentive stock options to be a significant component of executive compensation as it allows the Company to reward each Named Executive Officers efforts to increase value for shareholders without requiring the Company to use cash from its treasury. Stock options are generally awarded to directors, officers, consultants and employees at the commencement of employment and periodically thereafter. The terms and conditions of the Companys stock option grants, including vesting provisions and exercise prices, are
governed by the terms of the Companys stock option plan (the Stock Option Plan) and are determined by the Board as a whole.

Long Term Compensation and Option Based Awards



The Company has no long term incentive plans other than the Stock Option Plan. The Companys directors, officers, consultants and employees are entitled to participate in the Stock Option Plan. The Stock Option Plan is designed to encourage share ownership and entrepreneurship on the part of the senior management and other employees, The Board believes that the Stock Option Plan aligns the interests of the Named Executive Officer and the Board with shareholders by linking a component of executive compensation to the longer term performance of the Companys common shares. Options are granted by the Board of Directors. In monitoring or adjusting the option allotments, the Board takes into accounts its own observations on individual performance (where possible) and its assessment of individual contribution to shareholder value, previous option grants and the objectives set for the Name Executive Officers and the Board. The scale of options is generally commensurate to the appropriate level of base compensation for each level of responsibility.



In addition to determining the number of options to be granted pursuant to the methodology outlined above, the Board also makes the following determinations:



 parties who are entitled to participate in the Stock Option Plan;



 the exercise price for each stock option granted;



 the date on which each option is granted;



 the vesting period, if any, for each stock option;



 the other material terms and conditions of each stock option grant; and



 any re-pricing or amendment to a stock option grant.



The Board makes these determinations subject to and in accordance with the provisions of the Stock Option Plan. The board of directors reviews and approves grants of options on an annual basis and periodically during a financial year.



Pursuant to the Companys Stock Option Plan, the Companys Board of Directors grants options to directors, officers, consultants and employees as incentives. The level of stock options awarded to a Named Executive Officer (as defined below) is determined by his or her position and his or her potential future contributions to the Company.

Long Term Incentive Plan (LTIP) Awards



The Company does not have any long-term incentive plans and, save as disclosed above, no remuneration payments were made, directly or indirectly, by the Company to its Named Executive Officers during the year ended March 31, 2010.



An LTIP means any plan providing compensation intended to serve as an incentive for performance to occur over a period longer than one fiscal year whether performance is measured by reference to financial performance of the Company or an affiliate or the price of the Companys shares but does not include option or stock appreciation rights plans or plans for compensation through restricted shares or units.



Incentive Plan Awards



The Company currently has in place a stock option plan for the purpose of attracting and motivating directors, officers, employees and consultants of the Company and advancing the interests of the Company by affording such person with the opportunity to acquire an equity interest in the Company through rights granted under the plan to purchase shares of the Company.



The Stock Option Plan is administered by the board of directors of the Company and provides that a majority of members of the board participating in any decisions as to a grant of options under the Stock Option Plan shall be persons who are not employees of the Company.  Options may be granted at any time to any director, officer, service provider or employee (who shall be a full-time salaried) of the Company or its subsidiaries, taking into consideration, among other things, the past, present and potential contribution of a particular director, officer, service provider or employee to the success of the Company, the value of his or her services to the Company and any other factors which the Board of Directors may deem proper and relevant provided that a director to whom any option may be granted may not participate in the discussion of the Board of Directors to grant such option .



Subject to the provisions of the Stock Option Plan, the Board of Directors shall determine the time or times when options shall be granted, the number of Common Shares for which any option may be granted, the option exercise price at which Common Shares may be purchased under any option, the conditions, if any, to be satisfied before any option may be exercised and the expiry date of any option and cause the Company, subsequent to the grant of an option, to enter into an option agreement with each participant evidencing each option granted which shall incorporate such terms as the board of directors in its discretion deems consistent with the Stock Option Plan.  The Stock Option Plan provides that the terms and conditions upon which an option is granted need not be the same for each participant.



The maximum term of any option granted under the Stock Option Plan is ten (10) years from the date of grant of the option.  However, it is currently the Companys practice to grant options that expire five (5) years after the date of grant.  The expiration of any option is accelerated if the optionees employment or cessation of involvement with the Company terminates for any reason, other than for just cause, in which case the unexercised options granted to such optionee immediately terminate.  Subject to different arrangements being made between the Company and an individual optionee, the Stock Option Plan provides that the optionee has 90 days from the date of termination, resignation, removal or discharge to exercise all existing options, except in the case of death of an optionee, in which case options may be exercised by the legal representative (or by the person or persons to whom the rights of the optionee have passed by will or operation of law) generally for a period of 180 days from the date of death.  Other than on death, the options are non-transferable.

The maximum number of options that may be granted under the Stock Option Plan is 1,200,000, representing 9.6% of the currently issued and outstanding common shares of the Company.  In addition, the number of Common Shares which may be reserved for issuance on the exercise of options granted under the Stock Option Plan and granted under any other arrangement to any one individual (including insiders of the Company) shall not exceed 5% of the issued and outstanding Common Shares of the Company (on a non-diluted basis) at the time of the grant.



The exercise price of an option is set by the Board of Directors at the time of grant, based upon the closing price, on the trading market that the Companys shares are then available to be traded or quoted, of the Common Shares on the last trading day prior to the date of the grant.  Currently, the Companys Common Shares are traded on the Canadian National Stock Exchange (CNSX).  Payment of the exercise price of an option may be made by cash, certified cheque or bank draft.  The Stock Option Plan does not provide for any financial assistance to be provided to any optionee to facilitate the purchase of Common Shares.



The Board of Directors may suspend, amend or terminate the Stock Option Plan at any time without notice, provided that no outstanding option is adversely affected thereby unless the affected participant consents to such amendment.  The further approval of the Shareholders is required only for amendments that increase the number of shares available for issuance under the Stock Option Plan, that materially increase the benefits accruing to participants, or that materially change the class of persons eligible for the granting of options. As of August 31, 2010, the Company has issued and outstanding options to purchase 570,000 common shares, representing 4.4% of the issued and outstanding common shares of the Company, at exercise prices ranging from $0.12 to $0.80 per common share.



During fiscal 2010, no stock options were granted.



The following table discloses the particulars of the option-based awards granted to the Named Executive Officers under the Companys stock option plan at March 31, 2010:

|                |                                                         |                           |                        |                                                  |                                                              |

Capital gains realized on the disposition of common shares will not be subject to tax under the Act unless such common shares are taxable Canadian property of the holder within the meaning of the Act.  Common shares will generally not be taxable Canadian property to a holder unless, at any time during the five-year period immediately preceding a disposition, the holder, persons with whom the holder did not deal at arms length was considered to own under the Act 25% or more of the issued shares of any class or series of the Company.  Even if the common shares constitute taxable Canadian property to a particular holder, an exemption from tax under the act may be available under the provisions of any applicable international tax treaty.  In the case of residents of the United States (other than certain former residents of Canada), the Canada-United States Income Tax Convention (1980) (the US/Canada Tax Treaty) provides an exemption from tax unless the value of the common shares at the time of disposition is derived principally from real property situated in Canada (which the Company believes is not currently the case and does not expect to be the case in the future).



Dividends paid or credited on the common shares will be subjected to Canadian withholding tax under the Act at a rate of 25%, subject to reduction under the provisions of any applicable international tax treaty.  In the case of residents of the Unites States who own less than 10% of the Companys voting stock, the U.S./Canada Tax Treaty reduces the rate to 15%.  Under the U.S./Canada Tax Treaty, dividends paid to certain religious, scientific, charitable and similar tax-exempt organizations and certain pension organizations that are resident in, and exempt from tax in, the United States are exempt from Canadian non-resident withholding tax.  Provided that certain administrative procedures are observed regarding registration of such organizations, the Company will not be required to withhold such tax from payments made to such organizations.  Qualifying organizations that fail to follow the required administrative procedures will have to file a claim for refund to recover any amounts withheld.

ITEM 15: CONTROLS AND PROCEDURES



The Companys management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company (as defined in §240.13a-15(f) or 240.15d-15(f)).  Management conducted an evaluation of the effectiveness of its internal control over financial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on its evaluation, management concluded that a material weakness existed in its internal control over financial reporting as of March 31, 2010 related to the preparation of the Companys U.S. GAAP reconciliation. A material weakness is a deficiency or a combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. Specifically the Company has identified a lack of sufficient personnel with appropriate knowledge, experience and training in U.S. GAAP to facilitate the timely preparation of its U.S. GAAP reconciliation.  As a result of this material weakness, management has concluded that the Companys internal control over financial reporting as of March 31, 2010 was ineffective.



This annual report does not include an attestation report of the Companys registered public accounting firm regarding internal control over financial reporting. Managements report was not subject to attestation by the Companys registered public accounting firm pursuant to the permanent exemption rules of the Securities and Exchange Commission that permit the Company to provide only managements report in this annual report.



There have been no changes in internal control over financial reporting that occurred during the period covered by this annual report that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.  The public accounting firm that audited the Companys financial statements has not issued an attestation report on managements assessment of the Companys internal control over financial reporting.
