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. and subsidiaries (the Company) as at March 31, 2007 and 2006 and the consolidated statements of
operations, shareholders deficiency and cash flows for each of the years in the three-year period ended March 31, 2007. 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 as at March 31, 2007 and 2006 and the results of its
operations and its cash flows for each of the years in the three-year period ended March 31, 2007, 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 Independent Registered Chartered Accountants 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 dated July 16, 2007 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.

|   | 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 history of losses and an accumulated deficit of $100,263,264 as at
March 31, 2007. 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. 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.

|   | 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 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

|   | 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.

|   | 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.

|   | 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 substantively enacted 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.

|   | 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 the Company in the Partnership was completed to provide the Company with a portion of the cash
distributions expected to be received from the Partnership, net of repayment of the principle and interest and other partnership related expenses. The Company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 the Company this amount, the Company 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 the Company.

|   | This Partnership interest was reduced to $1,700,000 at March 31, 2007 (2006 - $5,600,000), as a result of distributions from the Partnership net of interest and related expenses of
$3,900,000 during fiscal 2007 (2006 - $5,100,000). In fiscal 2007, the Company reported $516,577 (2006 - $602,130; 2005 - $762,397) of Partnership income from distributions received from the Partnership. Also recorded was bank
loan interest of $214,994 (2006 - $272,290; 2005 - $440,227) and other partnership related expenses of $59,677 (2006 - $83,785; 2005 - $79,497). As of March 31, 2007, a quarterly Partnership income allocation of $112,061
(2006 - $49,317) was due and payable and recorded as a receivable on the balance sheet of the Company.

|   | 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.

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.

Balance of convertible debentures debt outstanding as at March 31, 2007 and 2006 is as follows:

|    | In August 2005, the Company obtained a Loan (2005 Loan) from an affiliate of Targa of $425,000. The 2005 Loan is payable on demand and earns interest at a rate of 10% per annum.
Additional amounts were provided on the 2005 Loan during the period ending March 31, 2006. The 2005 Loan is secured by an already existing General Security Agreement over Plaintrees assets. As of March 31, 2007, $1,221,389 (2006 -
$629,821) had been advanced with interest accrued to date of $127,545 (2006 - $30,593) for a total payable of $1,348,934 (2006 - $660,414).

|    | 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 9. As of March 31, 2007, the total Loan amount outstanding was $410,927 ($310,386 principal plus $100,541 of accumulated interest); 2006 - $376,849

| | The stock-based compensation expense of $2,244 (2006 - $59,296) included in general and administrative expenses in fiscal 2007 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 or 2007. 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

| | 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.

|    | Earnings (loss) per share has been calculated on the basis of net earnings (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 the years ended March 31, 2006 and 2005 presented, diluted loss per share equals basic loss per share due to the anti-dilutive effect of options and convertible instruments. For the year
ended March 31, 2007, the diluted weighted average common shares outstanding includes 17,475,116 dilutitive common shares from the potential conversion of the debentures. The outstanding number and type of securities that could potentially dilute
basic net earnings (loss) per share in the future are as follows:

|    | Under US GAAP, the convertible debentures issued in April 2005 and June 2005 would not be bifurcated into their debt and equity components. Accordingly, under US GAAP, the due to related parties
- convertible debentures would increase by $7,384 (2006 - $56,416, 2005 - $NIL), accretion of debt discount, operating expenses, loss from operations, net loss, and deficit would decrease by $49,032 (2006 - $41,645, 2005 -
$NIL), and equity component of convertible debentures would decrease by $98,061 (2006 - $98,061, 2005-$NIL).

|    | 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. 123R, Accounting for Stock-Based Compensation.

|    | Comprehensive income is recognized and measured under U.S. GAAP pursuant to Statement of Financial Accounting Standard (SFAS) 130, Reporting Comprehensive Income. This standard
defines comprehensive income as all changes in equity other than those resulting from investments by owners and distributions to owners. Comprehensive income is comprised of two components, net income and other comprehensive income
(OCI). OCI refers to amounts that are recorded as an element of shareholders equity but are excluded from net income because these transactions or events were attributed to changes from non-owner sources. Comprehensive income
(loss) is equal to net income (loss) in 2007,2006 and 2005.

|    | In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes. This interpretation clarifies the
criteria for recognizing income tax benefits under FASB Statement No. 109 Accounting for Income Taxes, and requires additional financial statement disclosure about uncertain tax positions. The interpretation is effective for fiscal years beginning
after December 15, 2006. The Company is currently evaluating the impact of this interpretation on its financial reporting.

|    | In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. This Statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting
principles (GAAP), and expands disclosures about fair value measurements. This Statement applies under other accounting pronouncements that require or permit fair value measurements, and where applicable simplifies and codifies related
guidance within GAAP and does not require any new fair value measurements. The Statement is effective for fiscal years beginning after January 1, 2008. Provisions of the Statement are to be applied prospectively except in limited situations. The
Company has not yet determined the impact of this statement on its financial reporting.

|--- | ---------------------
|   

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 accounts 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.

|    | The Canadian Institute of Chartered Accountants (CICA) has issued section 1530 of the CICA Handbook, Comprehensive Income. The section is effective for fiscal years beginning on or
after October 1, 2006 and defines comprehensive income as all changes in equity other than those resulting from investments by owners and distributions to owners. Comprehensive income is comprised of two components, net income and other
comprehensive income (OCI). OCI refers to amounts that are recorded as an element of shareholders equity but are excluded from net income because these transactions or events were attributed to changes from non-owner sources. The
Company does not expect the adoption of this standard to cause any material impact on its financial statements since comprehensive income (loss) is equal to net income (loss) in 2007, 2006 and 2005.
