ITEM 4:  INFORMATION ON THE COMPANY



A.

History and Development of the Company



Incorporation



Plaintree is the continuing company resulting from the amalgamation of CANAI Computer and Network Architecture Inc., 2879484 Canada Limited and Plaintree Systems Inc. (Old Plaintree) under the Canada Business Corporations Act pursuant to articles of amalgamation dated May 20, 1993.  The Companys articles of amalgamation were amended: (i) on November 27, 1997, to create 7,000 Series I convertible preferred shares; (ii) on April 7, 1998, to permit the directors of the Company to determine, subject to the minimum and maximum numbers set out in its articles, the number of directors of the Company and to appoint one or more additional directors until the following annual meeting of shareholders provided the number so appointed does not exceed one third the number of directors elected at the previous annual meeting; and (iii) on June 2, 1998, to create 9,000 Series II convertible preferred shares.  The Companys head office is located at 110 Decosta St., Arnprior, Ontario, Canada K7S-3X1.



As of the date of this 20-F, the Company has a wholly-owned inactive subsidiary, Plaintree Systems Corporation, a corporation incorporated under the laws of the State of Delaware in June 1993 and a wholly-owned inactive subsidiary, 4178611 Canada Inc. (4178611), incorporated under the Canada Business Corporations Act on July 8, 2003.



At the end of fiscal 2005, the Company made a decision to reorganize its business by starting the process of transferring all of its intellectual property (IP) to 4178611.  The reorganization will be completed in two steps. The first step, completed at the end of fiscal 2005, involved the grant by the Company to 4178611 of an exclusive license to use the IP on the payment of a one-time license fee of $12,000,000, which fee was paid by the delivery of a promissory note in favour of the Company.  The license term is four years. The promissory note is payable on demand and bears no interest.  The second step will involve the actual transfer of the IP to 4178611 to be completed following receipt of shareholder approval of the transfer at a future meeting of the shareholders of the Company. The Company will not be seeking the approval of its shareholders at the meeting of shareholders scheduled for September 28, 2006. No date has yet been set by the Company to seek the approval of the transfer of the IP. Until the transfer is completed,  the IP will remain owned by the Company and will be subject to the licence granted to 4178611.



Other than these subsidiaries listed above, the Company does not hold an equity interest in any other corporation.



Headquartered in the Ottawa region of Ontario, Plaintree designs, develops and manufactures a series of infrared optical wireless transmission links. The Companys mission is to become a global leader in the field of FSO, providing a solution for the broadband access bottleneck or Last Mile connection problems



Recent Developments



The Company has undergone several changes over the past three years including a significant down-sizing of operations and the completion of financial restructuring during the fiscal year ended March 31, 2003.







---











Corporate Strategy



Plaintree has carefully managed its fiscal resources over the past 3 years and continues to wait for a recovery to occur within the wireless sector. In fiscal 2005, the Company made a preliminary conclusion that a recovery was under way and during fiscal 2005 increased its sales force and expenditures on sales and marketing and research and development activities. However, the recovery has proven to be taking longer than expected. In fiscal 2006, the Company scaled back its sales and marketing and research and development activities. During this period the Company continues its sales efforts and such efforts have resulted in the Companys products being tested by several large North American MSOs, the main telco's in Mexico, India, Singapore and South America.  Several potential customers have indicated they will begin orders soon, however no orders have been received yet from these potential customers.



As the Companys legacy products are not currently producing sufficient revenue to sustain the continuing operations of the Company, the Company has increased providing management services to related parties and earning income through its investment in the Buhler Manufacturing Partnership to mitigate its losses and provide capital to continue operations. The requisition of additional management services is at the discretion of the related party with no minimum commitment and the services, and related income, may cease at any time. Additionally, the Partnership income to Plaintree is derived from income generated by the Partnership and as such is beyond Plaintrees control and subject to uncertainty. It is also subject to a maximum net distribution to the Company of $1,400,000 of which the Company has received $1,129,500 through March 31, 2006, including $300,000 that was received out of the original bank line of credit but has not yet been included in Plaintree income. Once the maximum net distribution has been provided to the Company, it will have no further rights to any distributions from the Partnership.



3 Year History



Investment in Partnership and related Bank Loan



In fiscal 2004, the Company acquired a 49% equity interest in the Buhler Manufacturing Partnership (the Buhler Partnership).  The Buhler Partnership is a general partnership and as such Plaintree is jointly and severally liable with the other partners of the Partnership for the debts and obligations of the Partnership if the Partnership is unable to satisfy the same, subject to a right of recovery by Plaintree from the other partners on the basis of their respective ownership interest in the Partnership.



Plaintree is not involved in the day to day management of the Partnership.  In a related transaction, Plaintree obtained a non-recourse credit facility (the "Credit Facility") from a Canadian chartered bank in the amount of $20,300,000 to fund its required $20,000,000 capital contribution to the Partnership, to cover related acquisition expenses and to fund its payment obligations under the proposal approved by its creditors in July 2003.  The only security pledged for the Credit Facility is the Partnership Interest itself and the Credit Facility is repaid only from cash distributions received from the Partnership and not from Plaintrees general working capital.  The credit facility is guaranteed by the Partnership.



See Item 5.A Buhler Partnership Interest and Item 5.B. Investment in Partnership and Related Bank Loan for further details.



2005 TSX Delisting



The common shares of Plaintree were delisted by the Toronto Stock Exchange (the TSX) as of the market close on October 17, 2005 for failure to meet the continued listing requirements of the TSX.



Discontinuance of Previous Reorganization Transaction



In 2003, the Company had reported that it was reorganizing its corporate structure by transferring all of its operating assets and liabilities to a wholly-owned subsidiary (the Proposed Transfer Transaction).  However, the Company decided to not complete the reorganization after a further examination of the ongoing costs to implement the Proposed Transfer Transaction.

Business Overview



Pursuant to the Canadian Institute of Chartered Accounts Handbook Section 1701, operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision making group, in making decisions regarding how to allocate resources and assess performance.  The Companys chief operating decision maker is the Chief Executive Officer.



To date, the Chief Executive Officer has viewed the Companys operations as principally one business segment: the design, development, manufacture, marketing and support of computer networking products. The Company from time to time provides management services to related companies.   In fiscal 2006, the Company increased its provision of management services to related parties for a fee.





The Company determines the geographic location of revenues based on the location of its customers.  All of the Company's assets are primarily located in Canada.

Overview



Plaintree designs, develops, manufactures, markets and supports infrared optical wireless transmission links.  Plaintree will continue to provide support of the Companys switching equipment to its customers.  The Companys goal is to become a global leader in the field of FSO, which is becoming the accepted terminology for optical wireless.  This is based on the combined attributes of the Companys optical wireless engineering expertise with its specialization in LED technology, and the solution that the optical wireless links provide to the broadband access bottleneck or the last mile connection problem.



Key elements of the Companys strategy to achieve this goal include developing and manufacturing a broad range of the WAVEBRIDGE FSO links to provide high-speed network connections for a variety of customers.   The Company intends to continue to build a global sales presence through a network of VARs (Value Added Resellers) and VAIs (Value Added Integrators) strategically positioned around the world.



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 as they require no licensing.  The high deployment densities of RF and Microwave systems are causing 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 it a very attractive solution.



Plaintree specializes in LED technology.  Although FSO refers to both laser and LED technologies, they differ in many respects including eye-safety, reliability and atmospheric attenuation.







---













The WAVEBRIDGE links have a Class 1 eye hazard rating from the IEC (International Electrotechnical Commission) and the American National Standards Institute (ANSI), the most eye-safe rating possible. The Class 1 rating means that the WAVEBRIDGE LED links can be viewed for any length of time, with or without binoculars under all foreseeable circumstances. This is of tremendous importance as binoculars or other viewing aids are often used in the initial alignment of optical wireless equipment.



The Company also provides management services to related parties for a fee.



Background



Founded in 1988, Plaintrees original focus was engineering and manufacturing intelligent network switches that quickly gained a reputation for their robustness and reliability.   Many of these switches continue to be in use as network backbones around the world.



As part of a business arrangement with Targa Group Inc. (Targa) in 2000, now Plaintrees largest shareholder and a related party, Plaintree hired key members of Targas management team.  Shortly after the Targa business arrangement, Plaintree completed a strategic acquisition that positioned the Company to become a leader in the optical wireless networking market. Plaintree purchased the assets of ATS, an early entrant into the field of optical wireless communication.  Established in 1985, ATS introduced its first wireless LANs in 1991, under the name FiRLAN.



Plaintree was to remain a switching manufacturer with a secondary line of optical wireless.  However, the markets for Plaintrees products have changed dramatically since fiscal year 2001.  Switching supply has grown and demand has fallen, leading to the predictable fall in margins.  Optical wireless on the other hand has a market that  appears ready to grow.  Plaintree decided that the interests of its shareholders would be best served by focusing management, marketing, sales, and manufacturing efforts, and financial resources in serving the optical wireless market rather than on the lower margin, highly competitive network switching market.



Products



Plaintree offers a series of optical wireless links to meet a broad range of customer requirements.  All FSO communications systems need line-of-sight for connectivity.  The only factor limiting the reliability of these systems is fog.  Installation planning can reduce this factor by calculating the fade margin to measure optimum distance between the links.



WAVEBRIDGE 300 Series



The 300 Series is a lightweight, easily transported design, intended for indoor use such as a small office. This is an ideal application for LEDs in particular as the units can be located near people without any concerns regarding eye hazards. It is also ideal for special events or emergency applications as set-up time is minimal and the equipment can be moved easily.  This very cost-effective unit offers speeds of 10Mbps (megabits per second) and covering distances from 27 meters to 500 meters.  The 300 Series also offers a Multiplex unit that offers an additional E1/T1 line as well as the 10 Mbps. E1/T1 lines are essentially a telephone line.



WAVEBRIDGE 500 Series



The 500 Series is primarily an outdoor system but can also easily be mounted indoors to operate through windows.  It provides a variety of connection speeds from E1 or T1 through to 155 Mbps (megabits per second) Ethernet or a combination of both.  With a range of up to 2000 meters, businesses can now eliminate the hassles of last mile connectivity and get high speed network connections in just a few hours. This solution is favoured by Internet Service Providers (ISPs), cellular operators and information technology (IT) managers due to its reliability and rapid installation. Businesses can connect offices or create their own backbone across rivers, highways, streets or courtyards.

WAVEBRIDGE 6000 Series



The 600 Series is an open protocol, full duplex system offering speeds up to 100 Mbps Fast Ethernet/155 Mbps Asynchronous Transfer Mode (ATM) up to 2000 meters. This product meets the requirements of customers such as ISPs, cellular operators and enterprise customers who need greater bandwidth than 10 Mbps.



WAVEBRIDGE WB SM



The WBSM is the newest addition to the FSO product line.  This new product line is an industry unique solution that has been designed specifically for the Multi System Operator (typically cable companies) to address the small to medium business customer.  Plaintree is presently the only company in the world that has a solution for this market.  The key attributes for this product are: speeds from 1 to 155Mbps, 100% eye-safe, and carries a wide beam for sway and vibration protection. The wide beam allows unique flexible mount options including towers, poles and cable strands. Because of the WBSM's unique attributes and low cost, this wireless device will put FSO on the map.



Applications



Plaintrees range of WAVEBRIDGE optical wireless links are designed for a variety of applications and customers.



Cellular and global system for mobile communications (GSM) operators can connect their base stations to micro-cells using Plaintrees WAVEBRIDGE optical wireless links. The use of FSO in this application helps the cellular companies avoid the frequency interference problems in areas of high congestion. They can also avoid the expense and delay of installing a fiber line to connect the micro-cells to the base station.



ISP customers are demanding more bandwidth and the capacity to carry rich media.  ISPs can use the WAVEBRIDGE links to deliver high bandwidth to business parks, MTUs (multi-tenant units), MDU (multi-dwelling units), hotels and strip malls and avoid the monthly cost of leased lines.



Businesses can connect remote buildings and create their own VPN (virtual private network).  This is of particular interest to government agencies that are looking for a high degree of channel security in their network.  Interception of the beam is immediately detectable by network management as it would cause interruption of the signal, immediately notifying IT managers.



Other applications include mining, manufacturing, tele-health and avionics.  The abundant use of RF systems in wireless applications will continue to cause frequency interference in some areas. FSO does not require spectrum licensing and does not experience RF overlap and interference. This is of great importance in areas where frequencies are highly regulated such as airports or hospitals.



Marketing; Sales and Customer Support



The Company markets its products world-wide through direct sales, value added resellers (VARs), distributors, systems integrators. and internet management.



Value Added Resellers (VARs)



The Plaintree reseller program has established close working relationships with a limited number of solution providers to serve as an extended sales and support force in Canada, United States and around the world. These programs combine a selective recruitment process with a comprehensive partnering methodology, allowing Plaintree authorized resellers to promote, sell and support the WAVEBRIDGE products. The authorized Plaintree reseller program ensures that resellers are carefully selected to offer focused value-added services or solutions.  They share Plaintree's commitment to customer satisfaction, and undergo extensive training to ensure they have the same world class selling and support skills as those required internally. The Company has signed contracts with approximately 40+ VARs throughout the world. Several of the contracted VARs have offices in multiple countries and regions.









---











Value Added Integrators (VAIs)



Plaintree has established a network of systems integrators who include WAVEBRIDGE products in total solutions for customers.  VAIs enjoy VAR purchasing privileges, and provide increased market exposure for Plaintree.



Customer Support



The Company believes that high-quality customer service and support is essential to developing long-term relationships with its customers.  Notwithstanding the layoff of 70% of its workforce following fiscal 2002, the Company continues to provide support to its customers for all of its products.  This includes technical advice, trouble diagnosis and repair.  Except for repair, such services are usually provided by telephone.  Since replacement of failed equipment is crucial to most customers, the Company provides overnight replacements (where possible) to its customers.  The Companys products typically have warranties of up to 12 months, with extended warranties also available.  To date, the Company has not experienced any significant warranty claims.



Research and Product Development



The market for the Companys products is characterized by uncertain conditions in the telecommunications market, rapidly changing technology, evolving industry standards and frequent new product introductions as well as product modifications.  As a result, the Company believes that its future success depends upon its ability to continue to enhance its product line and to develop new products complementary to its WAVEBRIDGE product line. As with all research and developments projects, it is difficult for the Company to predict with certainty the capital requirements or the time that will be required to bring any new products to market. The Company is presently exploring several alternative areas of research and development and the ongoing emphasis will be determined over the next few months by analysis of the potential market and the Company's available resources.



Operations



The Companys manufacturing operations are located within the Ottawa region near a substantial community of high technology companies.



The Companys manufacturing operations consist primarily of quality control, final assembly and testing.  The Company generally purchases components, many of which are prepared to the Companys specifications, and sorts these components into kits for subcontractors to assemble according to the Companys specifications.  The final assembly of major manufactured subcomponents, quality control testing, packing and shipping to the customer are performed by the Company at its manufacturing premises. Most of the Companys subcontractors and component 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.



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.  Although the Company seeks to develop alternative sources of supply for products that are available from only one supplier, it expects that it will continue to be dependent on single or limited source supplier relationships in the future.  These suppliers are generally major manufacturers.



Competition



The competitors for Plaintree 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.  As FSO addresses  some of the problems that are created by the abundant use of RF and microwave systems, this 20-F will focus and address competing FSO companies.







---













The competitive landscape for FSO has approximately 5 companies that have established themselves in the FSO market. Almost all of Plaintrees known FSO competition relies on laser-based transmitters, with eye-damage risks and signal degradation problems inherent in the technology. Only Plaintrees WAVEBRIDGE LED solution is certified to be the highest eye-safe Class 1 by the International Electrotechnical Commission. Some customers have eliminated all laser-based systems for safety concerns alone, and eye safety will become a major concern for residential and all indoor use.



The companies listed below use laser technology as opposed to Plaintrees LED technology.



Two of the larger FSO companies, AirFiber Inc. and Terabeam Corp., did focus on mesh network applications, involving several device installations and the cost of acquisition, installation and maintenance make these systems more appropriate to large carriers, and very large enterprises. Airfibre has ceased to exist and Terrabeam is now changing its product line. The systems are high-end (622 Mbps and higher), short range products.



fSONA Communications Corporation, a Canadian competitor, has laser equipment that provides data rates up to 1.25 Gbps (Gigabit Ethernet, OC-24).



Optical Access Inc. of Denver, Colorado, supplies optical wireless and IP switching and routing solutions using a mesh topology.



Other competitors include PAV Data Systems Ltd. in the United Kingdom and Canon Europa of Amsterdam, Netherlands.



The Company notes that in April 2006 Lightpointe Communications Inc., a company noted as a competitor in Previous Form 20-F filed by the Company, announced that it had ceased its operations.  It is too early to make any determination as to what effect, if any, this closure will have on the Companys business.



Plaintree has learned from its customers and VARs that the greatest market is for units capable of carrying E1 and T1 (i.e. 2 Mbps), with migration to 10 Mbps and 100/155 Mbps. Plaintree appears to be the one of few FSO companies that has targeted the high-volume, lower-cost, lower bandwidth market.



The Company believes its WAVEBRIDGE LED optical wireless links offer a very competitive alternative to the competitors laser products.  However, there can be no assurance that the Companys competitors will not succeed in developing products which are more effective than any that are being developed by the Company, or which would render the Companys technologies and products obsolete and non-competitive.



Many of the Companys competitors are significantly larger and have longer operating histories, greater name recognition and substantially greater financial, technical, personnel, research and development, marketing and other resources than the Company.  The Company expects competition to persist, intensify and increase results or financial condition. As well, such companies may have a better ability to withstand a prolonged downturn in the telecommunications market than the Company.



Intellectual Property



The Company principally relies on copyright, trade secret and contract law to protect its proprietary 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.

ITEM 5:  OPERATING AND FINANCIAL REVIEW AND PROSPECTS



A.

Operating Results



The following discussion and analysis is the responsibility of management and has been reviewed by the Audit Committee and approved by the Board of Directors.   The Board of Directors carries out its responsibilities for the financial statements and managements discussion and analysis principally through the Audit Committee, which is comprised exclusively of independent directors.



The following discussion of the financial condition, changes in financial condition and results of operations of Plaintree for the years ended March 31, 2006, 2005 and 2004 should be read in conjunction with the audited Consolidated Financial Statements and Notes of Plaintree for the year ended March 31, 2006 (Fiscal 2006 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 (GAAP).



Overview



Located in Arnprior, Ontario, Plaintree develops and manufactures the WAVEBRIDGE series of FSO wireless links using Class 1, eye-safe LED technology providing high-speed network connections for cable companies, ISPs, traditional telcos, GSM 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.



Plaintree has expanded its revenue generating activities to include management consulting services to related companies. The Company also earns income from its investment in a general partnership. The partnership arrangement is intended to provide Plaintree with income distributed from the partnerships net earnings subject to predetermined maximum amounts distributed. Once Plaintree has received its maximum aggregate net distribution of $1,400,000, of which it has received $1,124,400 through March 31, 2006, it no longer has any right to future distributions from the partnership.



The Companys shares have been delisted from the Toronto Stock Exchange and the Company has no present plans to start any action for relisting on any Canadian exchange until product sales increase significantly and this is not expected in the near future.  The Companys common shares continue to be quoted on the OTCBB in the United States.



Outlook



The Companys legacy products are not currently producing sufficient revenue to sustain the continuing operations of the Company. The Company has been earning management services revenue from related parties and earning income from its investment in the Partnership to mitigate its losses and provide capital to continue operations. The requisition of additional management services is at the discretion of the related party with no minimum commitment and the services, and related income, may cease at any time. Additionally, the Partnership income to Plaintree is derived from income generated by the Partnership and as such is beyond Plaintrees control and subject to uncertainty. It is also subject to a maximum net distribution to the Company of $1,400,000 of which the Company has received $1,129,500 through March 31, 2006, including $300,000 that was received out of the original bank line of credit but has not yet been included in Plaintree income. Once the maximum net distribution has been provided to the Company, it will have no further rights to any distributions from the Partnership.



The Companys total working capital deficit is approximately $8.2 million at March 31, 2006, of which $5.9 million is anticipated to be funded by distributions made by the Partnership to Plaintree. The remaining working capital deficit of $2.3 million and the Companys ongoing operations will need to be funded through additional capital in the near term. In addition, there is no assurance that the Company will realize future proceeds from the Buhler partnership to satisfy the remaining $5.9 million outstanding on the Bank loan, although the Partnership has provided a guarantee on that loan to the bank and the bank is not permitted to seek payment from Plaintree except for the proceeds distributed to Plaintree from the Partnership.



There can be no assurances that the Company will secure the necessary financing or achieve the operating results required to continue as a going concern. To date, the Company has not secured such funding either through an equity investment or strategic partnership. If these events do not occur, the Company may cease operations.



Selected Financial Information



The Company's consolidated financial statements are stated in Canadian dollars and are prepared in accordance with Canadian GAAP, which also conform in all material respects with accounting principles generally accepted in the United States, except as disclosed in note 20 to the Fiscal 2006 Statements.



As stated in Note 1 to the Fiscal 2006 Statements, the financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.  However, there is substantial doubt about the Company's ability to continue as a going concern because of the Company's losses during the past year of $330,011, a working capital deficit as at March 31, 2006 of $8,156,364, and an accumulated deficit of $101,233,016 as at March 31, 2006.  The Company's continued existence is dependent upon its ability to raise additional capital, to increase sales and ultimately become profitable.



There can be no assurances that the Company will secure the necessary financing or achieve the operating results required to continue as a going concern. To date, the Company has not secured such funding either through an equity investment or strategic partnership. If these events do not occur, the Company may cease operations.

Buhler Partnership Investment



In July 2003, the Company acquired a 49% interest in a general manufacturing partnership formally operating as Buhler Manufacturing ("Partnership") for $20,000,000. The Company obtained a line of credit (bank loan) of $20,300,000 to finance the acquisition and a restructuring completed at the time. The investment by Plaintree in the Partnership was completed to provide Plaintree with a portion of the cash distributions expected to be received from the Partnership, net of repayment of the bank loan principle and interest and other partnership related expenses. Plaintree's interest in the Partnership is limited to receiving its proportionate gross distributions from the income distributed by the Partnership to a maximum aggregate amount of approximately $21,610,000.  Once the Partnership has distributed to Plaintree this amount, Plaintree will automatically cease to be entitled to any further distributions and will effectively cease to be a partner. The gross partnership distributions to Plaintree after interest and related expenses are deducted are split at 94.3% to reduce the principle amount outstanding on the bank loan and 5.7% payable to Plaintree. Plaintree's net cash proceeds to be realized under the partnership agreement are expected to be a maximum aggregate amount of $1,400,000 (net of the payment of interest and principal on the bank loan, bank fees and related guarantee fees). Plaintree has received $1,124,400 of net distributions to date. When Plaintree has received its maximum aggregate distribution, the bank loan and all related expenses will be fully satisfied.  The bank loan is secured only against Plaintree's partnership interest and such loan is to be paid only from the distributions made to Plaintree by the Partnership.  The bank does not have any other security of the Company nor does it have the right to receive payment out of other amounts received by Plaintree for its other operations.



During fiscal 2006, Plaintree was allocated aggregate partnership distributions of $5,702,131 from the Partnership. From the distribution, a payment of $5,100,000 was made to reduce the bank loan. Plaintree's Partnership interest was reduced to $5,900,000 at March 31, 2006 (2005 - $11,000,000), as a result of distributions from the Partnership (net of interest and related fees and expenses) of $5,100,000 during fiscal 2006 (2005 - $5,300,000).



In fiscal 2006, the Company received payments totaling $273,395 (2005 - $258,835, 2004 -  $292,173) and reported $602,130 (2005 - $762,397, 2004 - $845,730) of Partnership income from distributions received from the Partnership.  Also recorded was Bank loan interest of $272,290 (2005 - $440,227, 2004 - $491,392) deducted before Plaintree's net proceeds and other partnership related expenses of $83,785 (2005 - $79,497, 2004 - $121,382), which is made up of Financing expense of $25,617 (2005 - $22,976, 2004 - $59,217) paid out of Plaintree's proceeds and Guarantee fees of $58,168 (2005 - $56,521, 2004 - $62,165) paid before Plaintree's net proceeds.  As of March 31,







---











2006, a quarterly Partnership income allocation of $49,317 (2005 - $49,649) was due and payable and recorded as a receivable on the Company's Fiscal 2006 Statements.



The Buhler Partnership is a general partnership and as such Plaintree is jointly and severally liable with the other partners of the Partnership for the debts and obligations of the Partnership if the Partnership is unable to satisfy the same, subject to a right of recovery by Plaintree from the other partners on the basis of their respective ownership interest in the Partnership.



The carrying value of the Partnership is assessed for impairment when there has been a loss in value that is other than temporary. As of March 31, 2006, the Partnership's unaudited summarized financial information is as follows:

Critical accounting estimates



The following critical accounting policies and significant estimates are used in the preparation of our consolidated financial statements:



Revenue recognition and warranties

Revenue from product sales is recorded on shipment provided evidence of an arrangement exists and collection is probable.  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.  Service revenue is recognized when the service is performed.  Deferred revenue arises when extended warranty contracts are paid in advance.



Management services revenue is recognized as services are delivered when there is persuasive evidence of an arrangement and collection is reasonably assured.



Investment in Partnership

The Company has a 49% interest in the Partnership.  The Company is accounting for the Partnership using the equity method whereby net partnership income (loss) increases (decreases) the investment and cash distributions reduce the investment.



Research and development costs







---











Research costs are expensed as incurred.  Development costs are deferred once technical feasibility has been established and all criteria for deferral under GAAP are met.  Such costs are amortized, commencing when the product is released, over the lesser of the expected life of the related product and three years.



Inventories



Finished goods are valued at the lower of cost (first-in, first-out) and net realizable value.  Work in process and raw materials are valued at the lower of cost and estimated realizable value.  Provisions for excess and obsolete inventory are made in the period in which management determines the inventory to be excess or obsolete.



Use of accounting estimates

The preparation of financial statements in conformity with Canadian generally accepted accounting principles requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure 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.  Management makes estimates related to revenue recognition and allowance for doubtful accounts, useful lives of assets, valuation of the investment in partnership, inventory, stock-based compensation, accrued liabilities, deferred revenue and bifurcation of convertible debentures.  Actual results could differ from the estimates made by management.



Stock option plan

The Company has stock option plans as described in Note 12 to the Fiscal 2006 Financial Statements.  Effective April 1, 2004, the Company adopted the new recommendations of section 3870 of the CICA Handbook ("CICA 3870") with respect to stock-based compensation.  The Company records an expense for employee options; the determination of stock-based compensation as further disclosed in Note 12 to the Fiscal 2006 Financial Statements is based on the fair value at the date of grant of the stock options.  The Company has not restated prior periods.  An adjustment of $195,498 was made to the opening balance of retained earnings of the fiscal 2005 period to reflect the cumulative effect of the change on the prior periods.



The Company uses the fair value based method to measure stock-based compensation for all stock-based awards made to non-employees, and for direct awards made to directors and employees of common shares, stock appreciation rights, and awards that result from settlement for cash or other assets.  Awards that the Company has the ability to settle in shares are recorded as equity whereas awards that the Company is required to or has a practice of settling in cash are recorded as liabilities.

Revenues



Management services revenue from related parties

Management services revenue of $1,545,750 in 2006 was earned by providing and charging for the services of certain Plaintree management under an arrangement with a company controlled by a significant shareholder. These services are provided as requested by the related party and the arrangement is cancelable at any time. There is no assurance that the Company will continue to earn this revenue going forward.



Product and service revenue



Total product and service revenue for fiscal 2006 was $145,584 as compared to $345,395 in fiscal 2005 and $258,739 in fiscal 2004.  Product and service revenue decreased from fiscal 2005 to fiscal 2006 by $199,811 primarily due to continued weak demand for telecommunications and wireless products resulting in revenues being below expectations.



Gross Margin



Total gross margin from management services revenue, from related parties, and product and service revenue for fiscal 2006 was $1,172,502 or 69.3% compared to 50.2% in fiscal 2005 and 86.2% in fiscal 2004. The gross margin for 2006 consists of margin on management services to related parties of $1,105,875 or 71.5% of management services revenue and margin on product and services revenue of $66,627 or 45.8% of sales. The gross margin on management services revenue consists of revenues earned less direct employee salaries and benefits. This margin is expected to remain consistent for any management services revenue charged to related parties going forward.



Gross margins related to product sales have been uncharacteristically high in the 2004-2006 periods due to the sale of legacy products whose inventory value had been previously written down. This effect is somewhat offset by additional write-offs incurred in fiscal 2005 and 2006.



Inventory levels were reduced in the last two successive fiscal periods; $22,011 was written down in fiscal 2006 while an amount of $55,794 was determined to be obsolete and written down from inventory in 2005.



Operating Expenses



Sales and marketing expenses



Sales and marketing expenses were $569,277, $820,824 and $453,718 in fiscal 2006, 2005 and 2004, 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 significant increases in sales and marketing expenses from fiscal 2004 to 2005 are mainly the result of salary expenses associated with an increase in sales and marketing staff. Fiscal 2004 sales and marketing expenses were significantly lower due to major cutbacks in the international sales force and marketing initiatives in response to the decreased revenue levels at that time.



The decrease in sales and marketing expense from 2005 to 2006 mainly relates to costs that have been allocated to the cost of services relating to employee costs incurred that are attributable to management services revenue charged







---











to related parties. Additionally, measures were taken in the second half of the year to reduce costs through headcount and salary reductions.



Finance and administration expenses



Finance and administrative expenses were $343,521, $835,218 and $514,764 in fiscal 2006, 2005 and 2004, respectively.  Finance and administration expenses consist primarily of costs associated with managing the Companys finances, which include financial staff, legal and audit activities as well as the amortization of capital assets.



Finance and administrative expense as a total decreased by $491,697 during fiscal 2006 as compared to fiscal 2005 and increased $320,454 compared to fiscal 2004. The decrease in finance and administration expenses from 2005 to 2006 mainly relates to costs that have been allocated to the cost of services related to employee costs incurred that are attributable to management services revenue charged to related parties.



Research and development expenses



Research and development expenses were $324,488, $314,304 and $424,431 in fiscal 2006, 2005 and 2004, respectively. Research and development expenditures consist primarily of software and hardware engineering personnel expenses, subcontracted research and development costs and costs associated with equipment and facilities.



Expenses were relatively flat between 2005 and 2006. The $110,127 drop in annual expense from fiscal 2004 to fiscal 2005 was predominately related to the reduction in personnel.



Interest and accretion



Interest and accretion expense consists of amortization of the discount on the debt portion of convertible debentures plus interest expense. Interest expense mainly relates to interest incurred on related party debt and lease arrears.



Amortization of discount on the convertible debentures that resulted from the fair value assigned to the equity component of convertible debentures was $373,145 during 2006, $328,473 during 2005 and $91,000 during 2004 (see Note 5 and Note 9 to the Fiscal 2006 Statements). Interest expense was $147,137, $74,722 and $68,067 in fiscal 2006, 2005 and 2004, respectively.



Other income (loss)



Other income (loss) during the fiscal year ended March 31, 2006 reflected a gain of $9,000 resulting from the sale of Company assets. Fiscal 2005 had a loss of $19,982 as compared to income of $385,452 in fiscal 2004.  The relatively large gain in 2004 primarily related to the $371,395 gain realized on the settlement of claims and debts of the unsecured creditors of the Company pursuant to the BIA proposal completed.



Partnership income, other partnership related expenses and Bank loan interest



In fiscal 2006, the Company recorded Partnership income allocations of $602,130 (2005 - $762,397, 2004 - $845,730).  Also recorded was bank loan interest of $272,290 (2005 - $440,227, 2004 - $491,392) and other partnership related expenses of $83,785 (2005 - $79,497, 2004 - $121,382), which is made up of financing expense of $25,617 (2005 - $22,976, 2004 - $59,217) and Guarantee fees of $58,168 (2005 - $56,521, 2004 - $62,165). See Item 5.A. Buhler Partnership Investment and Item 5.B Investment in Partnership and Related Bank Loan for further information.



Net Loss



The net loss for fiscal 2006 was $330,011 or $0.00 per share as compared to a net loss of $1,977,305 or $0.02 per share in fiscal 2005 and $710,451 or $0.01 per share in fiscal 2004.

The decrease in the working capital deficit was primarily a result of the reduction in the bank loan by $5,100,000. The most significant portion of the working capital deficient of $8,156,362, relates to the bank loan obtained by Plaintree to invest in the Partnership.  Payments of the bank loan are funded exclusively from the cash distributions paid to the Company from the Partnership and not out of other working capital or other funds of the Company.

Related Party Transactions



Fiscal 2006 interest expense of $147,137 (2004 - $74,722; 2003 - $68,067) is primarily interest on related party balances as described in Note 10 of the Fiscal 2006 Statements.

On December 4, 2003, the Loan was reduced by a cash payment of $189,614 to Targa as part of the settlement of the purchase of Debentures referred to in Note 8.  As of March 31, 2006, the total Loan amount outstanding was $376,849 ($310,386 principal plus $66,463 of accumulated interest; 2005 - $346,780 ($310,386 principal plus $36,394 of accumulated interest).

In 2003, this related party entered into a forbearance agreement with the Company whereby the Company agreed to repay the amounts owing and the related party was provided with a security interest in the form of a mortgage on the property owned by the Company.  As a result of the BIA proposal to creditors, the forbearance agreement is now in default and the amounts owing are due and payable.

The Buhler Partnership is a general partnership and as such Plaintree is jointly and severally liable with the other partners of the Partnership for the debts and obligations of the Partnership if the Partnership is unable to satisfy the same, subject to a right of recovery by Plaintree from the other partners on the basis of their respective ownership interest in the Partnership.



Plaintree is not involved in the day to day management of the Partnership.  In a related transaction, Plaintree obtained a non-recourse credit facility (the "Credit Facility") from a Canadian chartered bank in the amount of $20,300,000 to fund its required $20,000,000 capital contribution to the Partnership, to cover related acquisition expenses and to fund its payment obligations under the proposal approved by its creditors in July 2003.  The only security pledged for the Credit Facility is the Partnership Interest itself and the Credit Facility is repaid only from cash distributions received from the Partnership and not from Plaintrees general working capital.  The credit facility is guaranteed by the Partnership.



Other Contracts and Commitments



Product warranty







---











As part of the normal sale of product, Plaintree provides its customers with a standard one year product warranty and separately priced extended warranty as stated in Note 18 to the Audited Consolidated Financial Statements.  These warranties extend for periods generally ranging from one to two years from the date of sale.



Completion of Proposal to Creditors

On July 31, 2003, a certificate of full performance was received confirming that the Company had fulfilled its commitment to all creditors as agreed to under the formal proposal to creditors and the Company is now released from the protection of the Bankruptcy and Insolvency Act (Canada).



Changes in accounting policies



Stock-based compensation and other stock-based payments

Effective April 1, 2004, the Company adopted the new recommendations of section 3870 of the CICA Handbook with respect to stock-based compensation.  The Company records an expense for employee options; the determination of stock-based compensation as further disclosed in Note 12 is based on the fair value at the date of grant of the stock options.  The Company has not restated expenses of prior periods.  An adjustment of $195,498 was made to the opening balance of retained earnings of the fiscal 2005 period to reflect the cumulative effect of the change on the prior periods (see Note 12 to the Consolidated Financial Statements).



Controls and Procedures



The Companys management carried out an evaluation, with the participation of the Chief Executive Officer, of the effectiveness of the Companys disclosure controls and procedures for the annual filings covering the fiscal year ended March 31, 2006. Based upon that evaluation, the Companys Chief Executive Officer concluded that the Companys disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the applicable Canadian and U.S. Securities regulations is recorded, processed, summarized and reported, within the required time periods specified. There has not been any change in the Companys internal control over financial reporting in connection with the evaluation required by NI 51-102 that occurred during the fiscal year ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.



The Company has complied with multilateral instrument 52-109.

On March 31, 2006, the common shares of the Company were no longer trading on the TSX.



Compensation of Directors



During the fiscal year ended March 31, 2006, no cash remuneration was paid to the directors of the Company for their services as directors.  The Companys current policy is not to pay cash compensation to any individual for serving as director.  Rather, the directors receive incentive in the form of stock options, at the discretion of the board of directors, for serving as directors of the Company.  The purpose of granting such options is to assist the Company in compensating, attracting, retaining and motivating the directors of the Company and to align the personal interest of each of the directors to that of the shareholders.



During the fiscal year ended March 31, 2006, there were no options to acquire common shares of the Company granted to directors.



Incentive Stock Options



The management and the directors of the Company are of the view that to be able to attract the most suitable employees, officers and directors to the Company, it is often necessary to be able to offer them options to purchase common shares, as an incentive or inducement.   See Executive Compensation  Stock Option Plan.



As of August 25, 2006, the Company has issued and outstanding options to purchase 8,610.000 common shares at exercise prices ranging from $0.08 per common share to $2.31 per common share, of which options to purchase 8055520 common shares have been granted to directors and officers of the Company.  The following table is a summary of options which have been granted to directors, officers and employees of the Company, which were outstanding as at August 25, 2006.

Stock Option Plan



Stock Option Plan



The purpose of the Stock Option Plan is to encourage ownership of common shares by directors, officers, service providers and employees of the Company and its subsidiaries and thereby provide additional incentive for such directors, officers, service providers and employees of the Company and its subsidiaries to promote the success and business of the Company and its subsidiaries.



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, as approved by the shareholders at the last annual and special meeting held on September 16, 2004, is 12,000,000, representing 13.3% of the 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 quoted on the US OTCBB.  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 Company's 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 the Record Date, the Company has issued and outstanding options to purchase 8,610,000 common shares, representing 9.54 % of the issued and outstanding common shares of the Company, at exercise prices ranging from $0.08 to $2.31 per common share.

In 2003, this related party entered into a forbearance agreement with the Company whereby the Company agreed to repay the amounts owing and the related party was provided with a security interest in the form of a mortgage on the property owned by the Company.  As a result of the Companys proposal under the Bankruptcy and Insolvency Act (Canada) to creditors completed in 2003, the forbearance agreement is now in default and the amounts owing are due and payable.

See Items 4.A. and 5.B.

Exchange Controls



To the best of the Companys knowledge, there are no governmental laws, decrees, regulations or other legislation in Canada which may affect the import or export of capital by the Company, or, except as described in Item 10.E. below, the remittance of dividends, interest or other payments to non-resident holder of the Companys securities.



E.

Taxation



Canadian Income Tax



The following is a summary of the principal Canadian federal income tax considerations under the Income Tax Act(Canada) (the Act) generally applicable to holders of common shares who are not resident or deemed to be resident in Canada, who hold their common shares as capital property and who do not use or hold and are not deemed to use or hold common shares in carrying on business in Canada, except, in certain situations, holders who carry on an insurance business in Canada and elsewhere.  This summary is based on the current provisions of the







---











Act, the regulations thereunder, specific proposals to amend the Act or the regulations publicly announced by the Minister of Finance before the date hereof and counsels understanding of the current administrative practices published by Canada Customs and Revenue Agency but does not take into account provincial or territorial income tax laws.  This summary is not exhaustive of all possible income tax considerations and holders or prospective purchasers are advised to consult with their own tax advisers with respect to their particular circumstances.



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 carried out an evaluation, with the participation of the Chief Executive Officer, of the effectiveness of the Companys disclosure controls and procedures as of March 31, 2006. Based upon that evaluation, the Companys Chief Executive Officer concluded that the Companys disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the Securities and Exchange Commission. There has not been any change in the Companys internal control over financial reporting in connection with the evaluation required by Rule 13A-15(d) under the Securities Exchange Act of 1934 that occurred during the fiscal year ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.



The Companys management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company and evaluates the effectiveness of the Companys internal control over financial reporting.  Managements assessment of the effectiveness of the Companys internal control over financial reporting as of March 31, 2006 concluded that the internal control over financial reporting is effective and no material weakness in the Companys internal control over financial reporting was identified by management.  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.

ITEM 16B: CODE OF ETHICS

The Company will develop a code of ethics for its officers as circumstances improve.
