Report of Independent Registered Chartered Accountants

To the Board of
Directors and Shareholders of 
 Plaintree Systems Inc.

We have audited the accompanying consolidated balance sheets of Plaintree Systems Inc. as at March 31, 2006 and 2005 and the consolidated statements of operations, shareholders deficiency
and cash flows for each of the years in the three-year period ended March 31, 2006. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). These standards
require that we plan and perform an audit to obtain reasonable assurance whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the Company and subsidiaries as at March 31, 2006 and 2005 and the
results of its operations and its cash flows for each of the years in the three-year period ended March 31, 2006, in accordance with Canadian generally accepted accounting principles.

The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express
no such opinion.

Comments by Auditor on Canada-United States of America Reporting Difference

The standards of the Public Company Accounting Oversight Board (United States) require the addition of an explanatory paragraph when the financial statements are affected by conditions and events
that cast substantial doubt on the Company's ability to continue as a going concern, such as those described in Note 1 to the financial statements. Although we conducted our audits in accordance with both Canadian generally accepted auditing
standards and the standards of the Public Company Accounting Oversight Board (United States), our report to the Board of Directors and shareholders dated July 20, 2006 is expressed in accordance with Canadian reporting standards which do not permit
a reference to such conditions and events in the auditors' report when these are adequately disclosed in the financial statements.

PLAINTREE SYSTEMS INC.
Notes to the Consolidated Financial Statements 
 (in Canadian dollars)

1. DESCRIPTION AND CONTINUATION OF THE BUSINESS

The Company provides management services and specializes in developing optical wireless communications equipment for Local Area, Wide Area, Voice, Internet and Security Networks.

The consolidated 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 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.

The Company believes that future funding and certain sales-related efforts will provide sufficient cash flow for it to continue as a going concern in its present form. However, there can be no assurances that the
Company will achieve such results and to date, the Company has not secured such funding either through an equity investment or strategic partnership.  Accordingly, the consolidated financial statements do not include any adjustments related to the
recoverability and classification of recorded asset amounts or the amount and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

2. SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles. These principles conform in all material respects with accounting principles generally
accepted in the United States of America except as disclosed in Note 19.

Basis of presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The Company's foreign subsidiaries are inactive. All significant intercompany accounts and transactions have
been eliminated. The Company has a 49% interest in a partnership as disclosed in Note 3. 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.

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.

Capital assets

Capital assets are stated at cost. Amortization is provided using the following methods and rates:

Computer and office equipment
	3 years straight-lineFurniture and fixtures
	20% declining-basisBuilding
	20 years straight-line


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.

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 generally accepted accounting principles 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.

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.

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 net loss.

In prior years, the Company had active subsidiaries (reporting in foreign currencies) that were considered to be self-sustaining. The translation of the accounts of these subsidiaries resulted in the accumulated
foreign currency translation adjustment reported in the consolidated balance sheets.

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Stock option plans

The Company has stock option plans as described in Note 12. 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 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 deficit balance of fiscal 2005 to reflect the cumulative effect of the change on the prior periods resulting from expenses on options that were issued since January 1,
2002.

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 call for 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.

Use of accounting estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires the Company's 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.  Management makes estimates related to revenue
recognition and allowance for doubtful accounts, useful lives of capital 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.

Income taxes

The Company uses the asset and liability method to account for income taxes. Future income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying
amounts of existing assets and liabilities for accounting purposes, and their respective tax bases. Future income tax assets and liabilities are measured using statutory tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on future income tax assets and liabilities of a change in statutory tax rates is recognized in net income in the year of change. Future income tax assets whose recoverability
is not sufficiently likely are not recorded in these financial statements.

Investment in partnership

The Company accounts for its 49% investment in the Buhler Partnership using the equity method.

3. INVESTMENT IN PARTNERSHIP

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. The gross
partnership distributions to Plaintree after interest and related expenses are split at 94.3% to reduce the principal amount outstanding on the bank loan and 5.7% payable to
Plaintree.

This 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 expenses of $5,100,000 during fiscal
2006 (2005 - $5,300,000).      In fiscal 2006, the Company 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) 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). 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 balance sheet of
the Company.

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.

During fiscal 2006, Plaintree was allocated aggregate distributions of $5,702,131 from the Partnership. From this distribution, a payment of $5,100,000 was made to reduce the bank loan. Plaintree recorded gross
earnings from the Partnership of $602,130 representing the allocated earnings. In addition, Plaintree reduced its investment in the Partnership by $5,100,000 that was considered to be a repayment of its capital. The Company also incurred
bank loan interest of $272,290 and other Partnership related expenses of $83,785 and these amounts were paid out of the Partnership distribution to
Plaintree.

The Partnership allocates income to its partners and is not itself subject to tax.

Unaudited summarized financial information of the Partnership is as follows:

During fiscal 2006 and 2005, it became evident that the Company would not recover the cost of certain inventories reflected on the consolidated balance sheet. Accordingly, the Company wrote down its inventories by
$22,011 in fiscal 2006 (2005 - $55,794) to reflect its estimated realizable value.

5. DEFERRED CHARGES

Deferred charges represent payments to various entities to secure related party loans including the placement of the related party convertible debenture issue, related party demand loan and for Partnership related
legal and financing fees.

|                              |   | 2006      | 2005     
|----------------------------- | - | --------- | ---------

|Less accumulated amortization |   | (564,676) | (529,938)
|                              | $ | 5,836     | $ 38,574 

These charges are being amortized over the term of the related debts and amortization of $34,738 (2005 - $365,570; 2004 - $164,368) is included in finance and administration expenses in fiscal 2006.

Non-cash deferred charges relating to options granted to shareholders (Note 12) have been excluded from the payment of deferred charges reflected on the statement of cash flows.

6. DUE FROM RELATED PARTIES

Due from related parties consists of accounts receivable for management consulting services to a related party (a Company controlled by the same individual who controls
Targa) from Targa Group Inc. (Targa),
the Company's largest shareholder and from a subsidiary of Targa, and a loan to that same company, a subsidiary of
Targa, including interest. The loan earns interest at 10% and there is no set due date. During fiscal year 2006, a total of
$1,545,750 of management consulting fees was charged to a subsidiary of
Targa. The management consulting fees were charged at the exchange amount agreed to for those services. The Company received payment from a subsidiary of Targa of
$500,000 as at September 30, 2005 and subsequently loaned that amount back to the same related company in the 4th quarter of fiscal 2006. Management consulting fees of $1,045,750 remain owing to the Company as of March 31, 2006.

8. BANK LOAN

In July 2003, Plaintree obtained a non-recourse demand credit facility from a Canadian chartered bank in the amount of $20,300,000. The credit facility was used to finance its capital contribution to the
Partnership referred to in Note 3, to cover related acquisition expenses and to finance its payment obligations under the creditor proposal described below. Amounts outstanding under the credit facility incur interest at the banks prime rate.
Payments of interest and principal are due quarterly following cash distributions by the Partnership to the partners, including
Plaintree. Pursuant to the credit facility, the bank is entitled to be paid 94.3% of the amount of the cash distributions
from the Partnership paid to Plaintree prior to a demand and/or default under the credit facility and 100% of such distributions thereafter until the credit facility is repaid. The credit facility is guaranteed by a related party to one of
Plaintrees partners in the Partnership. In order to secure the guarantee, Plaintree is required to pay 1% of cash distributions from its Partnership interest up to a maximum of $200,000 to the party guaranteeing the credit facility.
Plaintree has secured its obligations to the bank under the credit facility by way of a specific pledge of its Partnership interest to the bank. Pursuant to the credit facility, the bank is only entitled to be paid out of the cash distributions to
Plaintree from the Partnership and has no recourse over any other cash flow of the Company.

During fiscal 2006, the bank loan was reduced by $5,100,000 (2005 - $5,300,000) as a result of distributions from the Partnership.

9. DUE TO RELATED PARTIES  CONVERTIBLE DEBENTURES

The Company has issued outstanding tranches of convertible debentures to related parties as follows:

|              |            |         |            |       | Components at Date of Issue

The debentures are convertible into common shares of the Company at the holders option at any time. They become due and payable two years from the date of issue at which point interest will begin to accrue at 10%
on any unpaid balances. Debentures may be repaid at any time by the Company with 30 days notice subject to the holders right to convert within that time period. All of the Companys assets were pledged as security for these convertible
debentures under an already existing general security agreement.

The Company determined the value of the debt and equity components of the Convertible Debentures in accordance with the substance of the contractual arrangement. The equity component representing the fair value of the
holders conversion option, is determined using the Black-Scholes option pricing model and is recorded to additional paid-in capital.

As at March 31, 2006, the discount resulting from the value attributed to the equity component was fully amortized. Principal values are due two years from the date of issue and accrues 10% interest from the due date
if not repaid.

Balance of convertible debentures debt outstanding as at March 31, 2006 and 2005 is as follows:

|            |                |                |              |               |                |           | Debt

During fiscal 2005, the Company granted 2,750,000 stock options at exercise prices varying between $0.08 and $0.12 with vesting periods of up to two years.

During fiscal 2004, of the 7,525,000 options granted, 5,000,000 options were granted to related parties and the Company recorded a deferred charge as a financing cost and an increase to additional paid-in capital of
$451,000 reflecting the fair market value of the options granted based on the application of the Black-Scholes pricing model. The deferred charge is being amortized over the period of the related debt (approximately one year).

The stock-based compensation expense of $59,296 (2005 - $80,221) included in general and administrative expenses in fiscal 2006 was determined using the fair value method, consistent with the requirements of
CICA 3870. This was calculated using a Black-Scholes option pricing model which indicates a weighted average fair value for options granted in the year of $0.05 per option in fiscal 2005 (2004 - $0.09) . The fair value is estimated on the
date of grant.

No options were granted in 2006. The weighted average fair value of all options granted during 2005 and 2004 was estimated as of the date of grant using the Black-Scholes option pricing model with the following
weighted average assumptions:

|                             | 2005 | 2004
|---------------------------- | ---- | ----
|Expected option life (years) | 3.1  | 2.5 
|Volatility                   | 123% | 184%
|Risk free interest rate      | 3.1% | 3.1%
|Dividend yield               | -    | -   

The Black-Scholes model used by the Company to calculate option values, as well as other currently accepted option valuation models, were developed to estimate the fair value of freely tradable, fully transferable
options without vesting restrictions, which significantly differ from the Companys stock option awards. These models also require highly subjective assumptions, including future stock price volatility and expected time until exercise, which
greatly affect the calculated values. Accordingly, management believes that this model does not necessarily provide a reliable single measure of the fair value of the Companys stock option awards.

13. OTHER INCOME (LOSS)

Other income (loss) is comprised of the following items:

|                                          |   | 2006  | 2005       |   | 2004

|Gain on creditor proposal                 |   | -     | -          |   | 371,395
|Gain (Loss) on disposal of capital assets |   | 9,000 | (9,232)    |   |        
|Miscellaneous                             |   | -     | -          |   | 15,344

The Company filed a proposal with its creditors in December, 2002. The Court approved the proposal in January, 2003. The gain on creditor proposal of $371,395 was realised on settlement of the final proposal to
creditors approved by the Ontario Superior Court of Justice on July 31, 2003. As part of this settlement, creditors received a maximum aggregate amount of $150,000.

During fiscal 2006, a foreign exchange gain of $1,690 was reclassified from the Other Income (Loss) section of statement of Operations and Deficit to the Product and service costs section as the gains or losses
were primarily attributable to international product sales.

14. BASIC AND DILUTED LOSS PER COMMON SHARE

Loss per share has been calculated on the basis of net loss divided by the weighted average number of common shares outstanding during the year. Diluted loss per common share is calculated by dividing the applicable
net loss 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. For all periods presented,
diluted loss per share equals basic loss per share due to the anti-dilutive effect of options and convertible instruments. The outstanding number and type of securities that could potentially dilute basic net loss per share in the future but that
were not included in the computation of diluted net loss per share, because to do so would have reduced the loss per share (anti-dilutive) for the years presented are as follows:

|    | The Company has claimed less research and development expenses for income tax purposes than has been reflected in the financial statements. These unclaimed expenses total approximately $20,593,000 (2005 -
$20,593,000; 2004 - $20,593,000) for Canadian federal and provincial income tax purposes. These are available without expiry to reduce future years' taxable income.
|   

The potential future benefits associated with the investment tax credits, tax losses, and unclaimed research and development expenses have not been reflected in these financial statements.

Current federal and provincial tax law in Canada includes provisions limiting the annual use of net operating loss and credit carryforwards in the event of certain defined changes in stock ownership. Accordingly, the
annual use of the Company's net operating loss and credit carryforwards could be limited according to these provisions in the event of certain changes in stock ownership.

Guarantees

The Company has entered into agreements that contain features which meet the definition of a guarantee under Canadian Accounting Guideline (AG) 14 and U.S. FASB Interpretation (FIN 45),Guarantors Accounting and Disclosure Requirements for Guarantees Including Indirect Guarantees of Indebtedness or Others.  The pronouncements define a guarantee to be a contract that
contingently requires the Company to make payments (either in cash, financial instruments, other assets, common shares of the Company or through the provision of services) to a third party based on changes in an underlying economic characteristic
(such as interest rates or market value) that is related to an asset, a liability or an equity security of the other party. The Company has the following guarantee that is subject to the disclosure requirements of AG 14 and FIN 45:

Product warranties

As part of the normal sale of product, the Company provides its customers with standard one year product warranties and separately priced extended warranties.  These warranties extend for periods generally ranging from
one to three years from the date of sale.  The following summarizes the accrual of deferred revenue that is recorded as part of current liabilities and deferred revenue in the accompanying consolidated balance sheets as at March 31, 2006 and 2005:

|    | Under Canadian GAAP, the Corporation accounts for its stock option plan in accordance with CICA 3870 which requires entities to account for employee stock options using the fair value based method, where compensation
cost is measured at fair value at the date of grant and is expensed over the stock-based awards vesting period. This method is substantially consistent for the periods presented with Statement of Financial Accounting Standards No. 123, Accounting
for Stock-Based Compensation, which was implemented retroactively as of April 1, 2004.

20. FINANCIAL INSTRUMENTS

Concentration of credit risk

Financial instruments which potentially subject the Company to a concentration of credit risk consist principally of cash, investments, due from partnership and trade receivables. The Company invests its excess cash in
high-quality financial instruments. The Company has credit evaluation, approval and monitoring processes intended to mitigate potential credit risks.  Anticipated bad debt loss has been provided for in the allowance for doubtful accounts.

Interest risk

The Company is financed through loans from related parties and a bank loan which bear interest at rates tied to the Canadian bank prime rate. Consequently, the Company is exposed to the risk of increases in the prime
rate.

Fair values

The fair values of amounts due to and due from related parties are not determinable as comparable arms length debts are not available.

The carrying amounts for trade accounts receivable, due from partnership and accounts payable and accrued liabilities approximate fair value due to the short maturity of these instruments or the terms of the
instrument. The carrying amount for the bank loan approximates fair value as the interest rate is reflective of rates currently available for similar debts.

21. COMPARATIVE FIGURES

Certain of the comparative numbers have been reclassified to conform to the current year's presentation.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

PLAINTREE SYSTEMS INC.

For the years ended March 31, 2006, 2005 and 2004

Date  July 24, 2006

The following discussion and analysis is the responsibility of management and has been reviewed by the audit committee (Audit Committee) and approved by the board of directors (the Board of
Directors) of Plaintree Systems Inc. (Plaintree or the Company). The Board of Directors carries out its responsibilities for the financial statements and managements discussion and analysis (MD&A)
principally through the Audit Committee, which is comprised exclusively of independent directors. Plaintrees Chief Executive Officer; who is also the Chief Financial Officer, in accordance with Multilateral Instrument 52-109, has certified
that he has reviewed the financial statements and this MD&A (the Filings). Based on his knowledge, these Filings do not contain any untrue fact or omit a material fact and the Filings present fairly our financial position, results of
operations and cash flows. The Companys certifying officers are responsible for establishing and maintaining our disclosure controls and procedures, and have in place the appropriate information systems, procedures and controls to ensure with
reasonable assurance that information used internally by management and disclosed externally is materially complete and reliable. Our Audit Committee and Board of Directors provide an oversight role with respect to all public financial disclosures
by the Company, and have reviewed this MD&A and the accompanying financial statements.

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).

Caution Regarding Forward Looking Information

This MD&A of the Company contains certain statements that, to the extent not based on historical events, are forward-looking statements based on certain assumptions and reflect Plaintrees current
expectations. Forward-looking statements include, without limitation, statements evaluating market and general economic conditions, 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 FSO industry; technological change; currency value fluctuation; general economic conditions worldwide, including in China; Plaintree's success
in developing and introducing new products and services, expanding existing distribution channels, developing new distribution channels and realizing increased revenue from these channels. 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. 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 in the documents filed from time to time with Canadian securities regulatory authorities and the United States Securities and Exchange Commission (SEC).

Overview

Located in Arnprior, Ontario, Plaintree develops and manufactures the WAVEBRIDGE series of Free Space Optical
(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.

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

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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.

The following table sets forth selected financial information from the Companys Fiscal 2006 Statements.

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 principal 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:

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 companies controlled by a significant shareholder.
These services are provided as requested by the related parties 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.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

During the fourth quarter of fiscal 2006 revenue was $269,240 and the net loss was $61,336. Expenses dropped in the fourth quarter of fiscal 2006 as compared to the third quarter mainly as a result of a
reduction in Convertible Debenture amortization expense as certain deferred charges were fully amortized by the end of the third quarter.

Cash

As at March 31, 2006, the Company held $18,337 in cash, a decrease of $78,531 from March 31, 2005.

Working Capital

Working capital represents current assets less current liabilities.  As at March 31, 2006, the Company had a working capital deficit of $8,156,362 compared to a working capital deficit of $13,095,324 at March
31, 2005.  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 deficiency 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.

Cash used in operating activities for fiscal 2006 was 1,031,598, an increase of $378,291 from $653,307 of the prior fiscal year. The increased use of cash in operating activities mainly relates to the
accumulation of related party receivables in 2006 offset by the decreased loss in 2006 compared to 2005.

Cash provided by Investing activities

assets.

Cash used in Financing activities

Cash provided by financing activities for fiscal 2006 was $944,067 compared to cash provided by financing activities of $359,499 of the prior fiscal year. Cash provided by financing activities mainly relate to
the issuance of convertible debentures and other proceeds from related parties of $946,067 in 2006 and $370,000 in 2005.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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.

Related Party Transactions

During fiscal 2006, total rent expense of $0 (2005 - $12,000; 2004 - $17,000) was paid to companies controlled by Targa for storage services. This amount is included in finance and administration expenses.

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.

August 2005 Affiliate Loan

In August 2005, the Board of the Company obtained a loan (Loan 2005) from an affiliate of Targa of $425,000. The Loan 2005 is payable on demand and earns interest at a rate of 10% per annum. Additional
amounts were provided on the Loan 2005 during the period ending March 31, 2006. The Loan 2005 is secured by an already existing General Security Agreement over Plaintrees assets. As of March 31, 2006, $629,821 had been advanced with
interest accrued to date of $30,593 for a total payable of $660,414.

Convertible Debentures

On June 30 2005, the Company completed a private placement of secured Convertible Debentures having a principal value of $145,000. $36,000 of the secured debentures was purchased by an affiliate of Targa, the
Companys largest shareholder and a related party, and $109,000 was purchased by a corporation related to a member of the board of directors of Plaintree.  The Convertible Debentures will mature two years after issuance and will be
non-interest bearing until the due date and thereafter will bear 10% interest per annum until paid in full. At anytime while the Convertible Debentures are outstanding, the holders have the right to convert the amounts outstanding thereunder into
Plaintree common shares at a conversion price of $0.04. If the full $145,000 of Convertible Debentures is converted, the Company will be required to issue 3,625,000 common shares in the aggregate. The Company will have the right to repay the
Convertible Debenture at any time on 30 days prior notice, subject to the debenture holders right to convert the Convertible Debentures into Plaintree common shares. In a related transaction, Targa also completed an unsecured loan to the
Company for $73,000 having terms substantially similar to the terms of convertible dentures with the exception that there are no conversion rights attached to the loan.

As at June 30, 2005, payment had been received for the $36,000 secured Convertible Debentures purchased by an affiliate of Targa and on July 11, 2005 payment had been received for the $109,000 secured
Convertible Debentures purchased by a member of the board of directors of the Company.

In April, 2005 Targa, the Companys largest shareholder and a related party completed a purchase of secured Convertible Debentures from the Company having a principal value of $220,000.  The Convertible
Debentures are due to be repaid in April 2007 (two years after issuance). The Convertible Debentures are non-interest bearing until the due date and thereafter will bear 10% interest per annum until paid in full. The Convertible Debentures are
secured by a general security agreement over the assets of the Company. At anytime while the Convertible Debentures are outstanding, Targa has the right to convert the amounts outstanding thereunder into Plaintree common shares at a conversion price
of $0.11. In the event that the full amount of the Debentures are converted, Targa will be issued 2,000,000 Plaintree common shares. The Corporation has the right to repay the Debenture at any time on 30 days prior notice, subject to
Targas right to convert the Debentures into Plaintree common shares.

On February 11, 2005, the Company completed a placement of secured Convertible Debentures having a principal value of $220,000. Targa, the largest shareholder of the Company, purchased $181,240 of the
Convertible Debentures. Targa is a related party of Plaintree and is controlled by David Watson, the Companys chief executive officer and a director, and Bill Watson, the Companys chairman and a director. The remaining $38,760 of the
Convertible Debentures was purchased by a member of the Companys Board of Directors. The due date for the payment of the Convertible Debentures is February 11, 2007. The Convertible Debentures are non-interest bearing until the due date and
thereafter will bear 10% interest per annum until paid in full and are secured by a general security agreement over the assets of the Company. At anytime while the Convertible Debentures are outstanding, the debenture holders have the right to
convert the amounts outstanding under the Convertible Debentures into Plaintree common shares at a conversion price of $0.065. In the event that the full amount of the Convertible Debentures are converted, Targa and the Board member will be
issued a combined total of 3,384,615 Plaintree common shares. The Company has the right to repay the Convertible Debenture at any time on 30 days prior notice, subject to Targas and the board members right to convert the Convertible
Debentures into Plaintree common shares.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

On December 16, 2003, the Company completed a placement of secured convertible debentures (Debentures) having a principal value of $900,000. Targa Group Inc., (Targa, the largest shareholder
of the Company), purchased all the Debentures. Of the $900,000 proceeds from the sale of the Debentures, $710,386 was utilized to retire outstanding credit facilities granted by Targa or its affiliates. The balance of the proceeds,
$189,614, was satisfied by a cash payment by Targa to the Company.

The due date for the payment of the Debentures was December 16, 2005. The Debentures were non-interest-bearing until the due date and thereafter bear 10% interest per annum until paid in full. As Debentures are secured
by a general security agreement over the assets of the Company.

November 19, 2003  Loan

On November 19, 2003, the Board of the Company agreed to accept a loan (Loan) from Targa, its largest shareholder, of $500,000 (net of related fees). The Loan is payable on demand and earns interest at
a rate of prime plus 5% per annum. The Loan is also secured by an already existing General Security Agreement over Plaintrees assets. 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). This amount is included in due to related parties.

Leased facilities

Until March 31, 2003, the Company leased facilities from a company controlled by Targa. Lease arrears including interest of $63,512 (2005 - $48,879) owing to this related party amounted to $282,320 (2005 -
$267,687). 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. This amount is still outstanding as at March 31, 2006 and is included in due to
related parties.

Off-Balance Sheet Arrangement

Investment in Partnership and related Bank Loan

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.

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 19 to the Audited Consolidated Financial
Statements. These warranties extend for periods generally ranging from one to two years from the date of sale.

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S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

Equity accounting for Partnership

The Company has a 49% interest in the Partnership. The Company is accounting for its interest in 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 replacement cost.  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 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 its investment in partnership, valuation of its inventory, stock-based compensation, certain accrued liabilities, deferred revenue and 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 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 Statements is based on the fair value at the date of grant of
the stock options. An adjustment of $195,498 was made to the opening balance of retained earnings of fiscal 2005 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.

Changes in accounting policies

Stock-based compensation and other stock-based payments

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 fiscal 2005 to reflect the cumulative effect of the change on the prior periods (see Note 12 to the Consolidated Financial Statements).
