REPORT OF INDEPENDENT REGISTERED CHARTERED ACCOUNTANTS

To the Board of Directors and Shareholders of Mitel Networks Corporation:

We have audited the consolidated balance sheets of Mitel Networks Corporation
and subsidiaries as of April 30, 2006, April 30, 2005 and April 24, 2005 and the
related consolidated statements of operations, shareholders' deficiency and cash
flows for each of the years ended April 30, 2006, April 24, 2005 and April 25,
2004 and the six day period ended April 30, 2005. These 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 the audit to
obtain reasonable assurance about 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 Mitel Networks Corporation and
subsidiaries as of April 30, 2006, April 30, 2005, and April 24, 2005 and the
results of their operations and cash flows for each of the years ended April 30,
2006, April 24, 2005 and April 25, 2004 and the six day period ended April 30,
2005 in conformity with accounting principles generally accepted in the United
States of America.

The Company is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audit 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.

On June 28, 2006 we reported separately to the shareholders of Mitel Networks
Corporation on our audits of financial statements for the same periods, prepared
in accordance with accounting principles generally accepted in the United States
of America. The attached financial statements also include Note 28,
reconciliation from US GAAP to Canadian GAAP.

           (The accompanying notes are an integral part of these consolidated financial statements)




                           MITEL NETWORKS CORPORATION
                     (incorporated under the laws of Canada)
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
         (in millions of US dollars, except share and per share amounts)


1.       BACKGROUND AND NATURE OF OPERATIONS

         Mitel Networks Corporation (the "Company") is a leading provider of
         integrated communications solutions and services for business
         customers. Through direct and indirect channels as well as strategic
         technology partnerships, the Company currently serves a wide range of
         industry vertical markets, including the education, government,
         healthcare, hospitality and retail in the United States ("US"), Europe,
         Middle East and Africa, Canada, Caribbean and Latin America, and
         Asia-Pacific regions.

         The Company was incorporated under the Canada Business Corporations Act
         on January 12, 2001. On February 16, 2001, the Company acquired the
         "Mitel" name and substantially all of the assets (other than Canadian
         real estate and most intellectual property assets) and subsidiaries of
         the Communications Systems Division of Zarlink Semiconductor Inc.
         ("Zarlink"), formerly Mitel Corporation.


2.       ACCOUNTING POLICIES

         These consolidated financial statements have been prepared by the
         Company in accordance with US generally accepted accounting principles
         ("GAAP") and the rules and regulations of the U.S. Securities and
         Exchange Commission (the "SEC") for the preparation of financial
         statements.

         Amounts less than fifty thousand dollars are deemed to be insignificant
         in these financial statements.

         a)  Fiscal Year End

         On April 24, 2005, the Company changed its fiscal year end from the
         last Sunday in April to April 30. The change in fiscal year end allows
         the Company to better align its reporting results with those of its
         industry peers. Results for the six-day transition period ("Transition
         Period") from April 25, 2005 to April 30, 2005 have been included
         pursuant to Rule 13a-10 of the Securities Exchange Act of 1934, as
         amended.

         b)  Basis of Consolidation

         The consolidated financial statements include the accounts of the
         Company and of its majority-owned subsidiary companies. Intercompany
         transactions and balances have been eliminated on consolidation.

         c)  Use of Estimates

         The preparation of the Company's consolidated financial statements in
         conformity with GAAP requires management to make estimates and
         assumptions that affect the reported amounts of assets and liabilities
         and disclosure of contingent assets and liabilities at the date of the
         consolidated financial statements and the reported amounts of revenues
         and expenses during the reporting periods.

         Estimates and assumptions are used for, but not limited to, the
         determination of the allowance for doubtful accounts, inventory
         allowances, special charges, depreciation and amortization, warranty
         costs, sales returns, pension costs, taxes, loss contingencies,
         goodwill and impairment assessments, and the valuation of stock
         options, shares, warrants and derivatives. Estimates and assumptions
         are reviewed periodically and the effects of revisions are reflected in
         the consolidated financial statements in the period that they are
         determined to be necessary. In the opinion of management, these
         consolidated financial statements reflect all adjustments necessary to
         present fairly the results for the periods presented. Actual results
         and outcomes could differ from these estimates.

         d)  Reporting Currency and Foreign Currency Translation

         Reporting Currency

         During fiscal 2004, the Company adopted the US dollar as its reporting
         currency. As a result of the change in reporting currency, the
         financial statements for all periods presented were translated from
         Canadian dollars to US dollars in accordance with the Financial
         Accounting Standards Board ("FASB") Statement No. 52, Foreign Currency
         Translation. Income statement balances were translated using
         weighted-average exchange rates over the relevant periods, assets and
         liabilities were translated at the exchange rate as of the balance
         sheet dates, and shareholders' deficiency balances were translated at
         the exchange rates in effect on the date of each transaction. The
         Company made this change to enhance the communication of its financial
         results with its shareholders and potential investors using the
         currency that is familiar to both groups. This presentation is also
         more consistent with the presentation of the financial results of its
         industry counterparts and competitors. There has been no change in the
         functional currencies used in preparing these consolidated financial
         statements.

                                       8



         Foreign Currency Translation

         The financial statements of the parent company and its subsidiaries are
         measured using their local currency as the functional currency. Assets
         and liabilities of the Company's foreign operations are translated from
         foreign currencies into US dollars at the exchange rates in effect at
         the balance sheet date while revenue, expenses and cash flow amounts
         are translated at weighted-average exchange rates for the period. The
         resulting unrealized gains or losses are recorded as a component of
         accumulated other comprehensive income (loss) in shareholders'
         deficiency until there is a reduction in the net investment in a
         foreign operation.

         Other monetary assets and liabilities, which are denominated in
         currencies foreign to the local currency of any subsidiary, are
         translated to the local currency at the exchange rates in effect at the
         balance sheet date, and transactions included in earnings are
         translated at weighted-average exchange rates during the period.
         Exchange gains and losses resulting from the translation of these
         accounts are included in other income (expense), net, in the
         Consolidated Statements of Operations.

         e)   Revenue Recognition

         The Company recognizes revenue when persuasive evidence of an
         arrangement exists, delivery has occurred, title and risk of loss have
         been transferred to the customer, the fee is fixed or determinable, and
         collection is reasonably assured.

         Software revenue is recognized when persuasive evidence of an
         arrangement exists, delivery has occurred in accordance with the terms
         and conditions of the contract, the fee is fixed or determinable, and
         collection is reasonably assured. For software arrangements involving
         multiple elements, revenue is allocated to each element based on the
         relative fair value or the residual method, as applicable, and using
         vendor specific objective evidence of fair values, which is based on
         prices charged when the element is sold separately. Revenue related to
         post-contract support ("PCS"), including technical support and
         unspecified when-and-if available software upgrades, is recognized
         ratably over the PCS term for contracts that are greater than one year.
         For contracts where the post contract period is one year or less, the
         costs are deemed insignificant, and the unspecified software upgrades
         are expected to be and historically have been infrequent, revenue is
         recognized together with the initial licensing fee and the estimated
         costs are accrued.

         Indirect channels

         The Company makes sales to distributors and resellers based on
         contracts with terms ranging from one to three years. For products sold
         through these distribution channels, revenue is recognized at the time
         the risk of loss is transferred to distributors and resellers according
         to contractual terms and if all contractual obligations have been
         satisfied. These arrangements usually involve multiple elements,
         including post-contract technical support and training. Costs related
         to insignificant technical support obligations, including second-line
         telephone support for certain products, are accrued. For other
         technical support and training obligations, revenue from product sales
         is allocated to each element based on vendor specific objective
         evidence of relative fair values, generally representing the prices
         charged when the element is sold separately, with any discount
         allocated proportionately. Revenue attributable to undelivered elements
         is deferred and recognized upon performance or ratably over the
         contract period.

         The Company's standard warranty period extends fifteen months from the
         date of sale and extended warranty periods are offered on certain
         products. At the time product revenue is recognized an accrual for
         estimated warranty costs is recorded as a component of cost of sales
         based on prior claims experience. Sales to the Company's resellers do
         not provide for return or price protection rights while sales to
         distributors provide for such rights. Product return rights are
         typically limited to a percentage of sales over a maximum three-month
         period. A reserve for estimated product returns and price protection
         rights based on past experience is recorded as a reduction of sales at
         the time product revenue is recognized. The Company offers various
         cooperative marketing programs to assist its distribution channels to
         market the Company's products. Allowances for such programs are
         recorded as marketing expenses at the time of shipment based on
         contract terms and prior claims experience.

         Direct channels

         The Company sells products, including installation and related
         maintenance and support services, directly to customers. For products
         sold through direct channels, revenue is recognized at the time of
         delivery and at the time risk of loss is transferred, based on prior
         experience of successful compliance with customer specifications.
         Revenue from installation is recognized as services are rendered and
         when contractual obligations, including customer acceptance, have been
         satisfied. Revenue is also derived from professional service contracts
         with terms that range from two to six weeks for standard solutions and
         for longer periods for customized solutions. Revenue from customer
         support, professional services and maintenance contracts is recognized
         ratably over the contractual period, generally one year. Billings in
         advance of services are included in deferred revenue. Revenue from
         installation services provided in advance of billing is included in
         unbilled accounts receivable.

         Certain arrangements with direct customers provide for free customer
         support and maintenance services extending twelve months from the date
         of installation. Customer support and maintenance contracts are also
         sold separately. When customer support or maintenance services are
         provided free of charge, such amounts are unbundled from the product
         and installation revenue at their fair market value based on the prices
         charged when the element is sold separately and recognized ratably over
         the contract period. Consulting and training revenues are recognized
         upon performance.

                                       9


         The Company provides long-term outsourcing services of communication
         systems. Under these arrangements, systems management services
         ("Managed Services") and communication equipment are provided to
         customers for terms that typically range from one to ten years. Revenue
         from Managed Services is recognized ratably over the contract period.
         The Company retains title and risk of loss associated with the
         equipment utilized in the provision of the Managed Services.
         Accordingly, the equipment is capitalized as part of property and
         equipment and is amortized to cost of sales over the contract period.

         f) Cash and Cash Equivalents

         Cash and cash equivalents are highly liquid investments that have terms
         to maturity of three months or less at the time of acquisition, and
         generally consist of cash on hand and marketable securities. Cash
         equivalents are carried at cost, which approximates their fair value.

         g) Restricted Cash

         Restricted cash represents cash provided to support letters of credit
         outstanding and to support certain of the Company's credit facilities.

         h) Allowance for Doubtful Accounts

         The allowance for doubtful accounts represents the Company's best
         estimate of probable losses that may result from the inability of its
         customers to make required payments. The Company regularly reviews
         accounts receivable and uses judgment to assess the collectibility of
         specific accounts and based on this assessment, an allowance is
         maintained for those accounts that are deemed to be uncollectible. For
         the remaining amounts that are not specifically identified as being
         uncollectible, an allowance is estimated based on the aging of the
         accounts, the Company's historical collection experience, and other
         currently available evidence.

         i) Securitizations and Transfers of Financial Instruments

         The Company entered into a Receivables Purchase and Sale Agreement on
         April 16, 2004, whereby non-interest bearing trade receivables are
         transferred to a securitization trust. These transfers are accounted
         for as sales when the Company is considered to have surrendered control
         over the transferred receivables and receives proceeds from the trust,
         other than a beneficial interest in the assets sold. Losses on these
         transactions are recognized as other expenses at the date of the
         receivables sale, and are dependent in part on the previous carrying
         amount of the receivables transferred which is allocated between the
         receivables sold and the retained interest, based on their relative
         fair value at the date of transfer. Fair value is generally estimated
         based on the present value of expected future cash flows using
         management's best estimates of key assumptions such as discount rates,
         weighted average life of accounts receivable, and credit loss ratios. A
         servicing liability is recognized on the date of the transfer and
         amortized to income over the expected life of the transferred
         receivables. As of April 24, 2005, April 30, 2005 and April 30, 2006,
         there were no securitized receivables outstanding.

         j) Inventories

         Inventories are valued at the lower of cost (calculated on a first-in,
         first-out basis) or net realizable value for finished goods, and
         current replacement cost for raw materials. The Company provides
         inventory allowances based on estimated excess and obsolete
         inventories.

         k) Property and Equipment

         Property and equipment are initially recorded at cost. Depreciation is
         provided on a straight-line basis over the anticipated useful lives of
         the assets. Estimated lives range from three to ten years for equipment
         and twenty-five years for buildings. Amortization of leasehold
         improvements is computed using the shorter of the remaining lease terms
         or five years. The Company performs reviews for the impairment of
         property and equipment in accordance with FASB Statement No. 144,
         Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS
         144") whenever events or changes in circumstances indicate that the
         carrying amount of an asset may not be recoverable. Recoverability is
         assessed based on the carrying value of the asset and its fair value,
         which is generally determined based on the discounted cash flows
         expected to result from the use and the eventual disposal of the asset.
         An impairment loss is recognized when the carrying amount is not
         recoverable and exceeds fair value.

         Assets leased on terms that transfer substantially all of the benefits
         and risks of ownership to the Company are accounted for as capital
         leases, as though the asset had been purchased outright and a liability
         incurred. All other leases are accounted for as operating leases.

         l) Goodwill and Intangible Assets

         Intangible assets include patents, trademarks, and acquired technology.
         Amortization is provided on a straight-line basis over five years for
         patents and over two years for other intangible assets with finite
         useful lives. The Company periodically evaluates intangible assets for
         impairment in accordance with SFAS 144 whenever events or changes in
         circumstances indicate that the carrying amount of an asset may not be
         recoverable. Recoverability is assessed based on the carrying value of
         the asset and its fair value, which is generally determined based on
         the discounted cash flows expected to result from the use and the
         eventual disposal of the asset. An impairment loss is recognized when
         the carrying amount is not recoverable and exceeds fair value.

                                       10


         Goodwill represents the excess of the purchase price over the estimated
         fair value of net tangible and intangible assets acquired in business
         combinations. The Company reviews the carrying value of goodwill on an
         annual basis in accordance with FASB Statement No. 142, Goodwill and
         Other Intangible Assets ("SFAS 142"). Under SFAS 142 goodwill is not
         amortized, but is subject to annual impairment tests, or more
         frequently if circumstances indicate that it is more likely than not
         that the fair value of the reporting unit is below its carrying amount.
         The Company, upon completion of its annual goodwill impairment tests,
         determined that no impairments existed as of the balance sheet dates.

         m) Derivative Financial Instruments

         The Company uses derivatives, including foreign currency forward and
         swap contracts, to minimize the short-term impact of currency
         fluctuations on foreign currency receivables and payables. These
         financial instruments are recorded at fair market value with the
         related foreign currency gains and losses recorded in other income
         (expense), net, in the Consolidated Statements of Operations. The
         Company does not hold or issue derivative financial instruments for
         speculative or trading purposes. The Company also utilizes
         non-derivative financial instruments including letters of credit and
         commitments to extend credit.

         As explained in Note 20, the Company has issued convertible, redeemable
         preferred shares to investors. The preferred shares give the investors
         the right, at any time after five years to redeem the shares for cash.
         The redemption amount is equal to the original issue price of $1.00 per
         preferred share times the number of Series A and Series B Preferred
         Shares outstanding, plus any declared but unpaid dividends, plus the
         then current fair market value of the common shares into which the
         Series A and Series B Preferred Shares are convertible. The requirement
         to redeem the shares on an as-if-converted-to-common share basis
         qualifies as an embedded derivative under FASB Statement No. 133,
         Accounting for Derivative Instruments and Hedging Activities ("SFAS
         133"). Accordingly, the proceeds received from the issuance of the
         preferred shares were allocated between the embedded derivative and the
         preferred shares. The embedded derivative is then marked to market
         throughout the period to redemption with changes in value recorded in
         the Consolidated Statements of Operations.

         In addition, the make whole premium on the convertible notes and the
         redemption rights upon a fundamental change as described further in
         Note 16, qualify as a derivative, which will be marked to market
         throughout the period to redemption with changes in value recorded in
         the Consolidated Statements of Operations.

         n) Income Taxes

         Income taxes are accounted for using the asset and liability method.
         Under this approach, deferred tax assets and liabilities are determined
         based on differences between the carrying amounts and the tax basis of
         assets and liabilities, and are measured using enacted tax rates and
         laws. Deferred tax assets are recognized only to the extent that it is
         more likely than not, in the opinion of management, that the future tax
         assets will be realized in the future.

         o) Research and Development

         Research costs are charged to expense in the periods in which they are
         incurred. Software development costs are deferred and amortized when
         technological feasibility has been established, or otherwise, are
         expensed as incurred. The Company has not deferred any software
         development costs to date.

         p) Defined Benefit Pension Plan

         Pension expense under the defined benefit pension plan is actuarially
         determined using the projected benefit method prorated on service and
         management's best estimate assumptions. Pension plan assets are valued
         at fair value. The excess of any cumulative net actuarial gain (loss)
         over ten percent of the greater of the benefit obligation and the fair
         value of plan assets is amortized over the average remaining service
         period of active employees. The Company periodically assesses, and
         adjusts as necessary, the minimum pension liability recorded on the
         Consolidated Balance Sheet to equal the amount by which the accumulated
         benefit obligation exceeds the fair value of the plan assets.

         The discount rate assumptions used reflect prevailing rates available
         on high-quality, fixed-income debt instruments. The rate of
         compensation increase is another significant assumption used for
         pension accounting and is determined by the Company, based upon its
         long-term plans for such increases.

         The Company uses a March 31 measurement date for its defined benefit
         pension plan.

         q) Stock-Based Compensation Plan

         The Company has a stock-based compensation plan described in Note 22.
         The Company generally grants stock options for a fixed number of shares
         to employees and non-employees with an exercise price equal to the fair
         market value of the shares at the date of grant. The Company accounts
         for employee stock option grants in accordance with Accounting
         Principles Board Opinion No. 25, Accounting for Stock Issued to
         Employees ("APB 25"), and related interpretations. Under APB 25,
         options granted to employees and directors will result in the
         recognition of compensation expense only if the exercise price is lower
         than the market price of common shares on the date of grant. Under FASB
         Statement No. 123, Accounting for Stock-Based Compensation ("SFAS
         123"), the Company recognizes compensation expense in connection with
         grants to non-employees and former employees by applying the fair value
         based method of accounting and also applies variable plan accounting to
         such unvested grants. Had compensation cost for the Company's stock
         option plan been determined as prescribed by SFAS 123, pro forma net
         loss and pro forma net loss per share would have been as follows, using
         the following weighted-average assumptions:

                                       11




                                                                    Year Ended    Year Ended    6 Days Ended    Year Ended
                                                                     April 25,      April 24,     April 30,      April 30,
                                                                       2004          2005           2005            2006
         -------------------------------------------------------------------------------------------------------------------
                                                                                                     
         Net loss available to common shareholders,
          as reported (Note 22)                                   $     (33.4)     $  (55.2)     $    (1.7)      $  (51.5)

         Pro forma results disclosed are based on the provisions of SFAS 123
         using a minimum value option pricing model, which assumes no
         volatility, to calculate the fair value of employee stock options.
         Changes in the subjective input assumptions can materially affect the
         fair value estimate, and therefore the model used above does not
         necessarily provide reliable pro forma results.

         r) Net Loss per Common Share

         Basic loss per common share is computed using the weighted-average
         number of common shares outstanding during the period, with net loss
         adjusted for the impact of accreted interest on redeemable shares.
         Diluted loss per common share is computed using the treasury stock
         method and assumes that, if a dilutive effect is produced, all dilutive
         securities had been exercised at the later of the beginning of the
         fiscal period and the security issue date.

         s) Other Comprehensive Loss

         Other comprehensive loss is recorded directly to a separate section of
         shareholders' deficiency in accumulated other comprehensive loss and
         includes unrealized gains and losses excluded from the Consolidated
         Statements of Operations. These unrealized gains and losses consist of
         foreign currency translation adjustments, which are not adjusted for
         income taxes since they primarily relate to indefinite investments in
         non-Canadian subsidiaries, and minimum pension liability adjustments.

         t) Advertising Costs

         The cost of advertising is expensed as incurred, except for cooperative
         advertising obligations which are expensed at the time the related
         sales are recognized. Advertising costs are recorded in selling,
         general and administrative expenses. During fiscal 2006, the Company
         incurred $10.3 in advertising costs (2004 - $8.1; 2005 - $9.4;
         Transition Period - $0.2).

         u) Product Warranties

         The Company's product warranties are generally for periods up to
         fifteen months but can be extended up to five years. At the time
         revenue is recognized, a provision for estimated warranty costs is
         recorded as a component of cost of sales. The warranty accrual
         represents the Company's best estimate of the costs necessary to settle
         future and existing claims on products sold as of the balance sheet
         date based on the terms of the warranty, which vary by customer and
         product, historical product return rates and estimated average repair
         costs. The Company periodically assesses the adequacy of its recorded
         warranty provisions and adjusts the amounts as necessary.

         v) Recent Accounting Pronouncements

         In November 2004, the FASB issued Statement No. 151, Inventory Costs
         ("SFAS 151"). SFAS 151 amends the guidance in ARB No. 43, Chapter 4,
         "Inventory Pricing," to clarify the types of costs that should be
         expensed rather than capitalized as inventory. Among other provisions,
         the new rule requires that items such as idle facility expense,
         excessive spoilage, double freight, and rehandling costs be recognized
         as current-period charges regardless of whether they meet the criterion
         of "so abnormal" as stated in ARB No. 43. Additionally, SFAS 151
         requires that the allocation of fixed production overhead to the costs
         of conversion be based on the normal capacity of the production
         facilities. SFAS 151 is effective for fiscal years beginning after June
         15, 2005, or for the Company's fiscal 2007 year-end. The Company is
         currently evaluating the requirements of SFAS 151 and has not yet fully
         determined the impact, if any, on the consolidated financial
         statements.

         In December 2004, the FASB issued Statement No. 123 (revised 2004),
         Share-Based Payment (""SFAS 123R''), which revises SFAS 123 and
         supercedes APB 25. SFAS 123R requires all share-based payments to
         employees, including grants of stock options, to be recognized in the
         financial statements based on their fair values. The statement is
         effective for the Company as of the beginning of fiscal 2007. The
         Company will be applying the provisions of this statement prospectively
         to new awards and to awards modified, repurchased, or cancelled after
         May 1, 2006 with the associated compensation expense being recognized
         on a straight-line basis over the requisite service period. As the
         requirements of SFAS 123R depend on future awards, modifications,
         repurchases or cancellations, the impact on the Company's consolidated
         financial statements when this statement becomes effective is not yet
         fully determinable.

                                       12


         In December 2004, the FASB issued SFAS No. 153, Exchanges of
         Non-monetary Assets. This standard amended APB Opinion No. 29,
         "Accounting for Non-monetary Transactions," to eliminate the fair value
         measurement exception for non-monetary exchanges of similar productive
         assets and replaces it with a general exception for exchanges of
         non-monetary assets that do not have commercial substance. A
         non-monetary exchange has commercial substance if the future cash flows
         of the entity are expected to change significantly as a result of the
         exchange. This statement is effective for all non-monetary asset
         exchanges completed by the Company starting fiscal 2007. The Company
         generally does not engage in significant non-monetary asset exchanges
         and the provisions of SFAS No. 153 are not expected to have a
         significant impact on the Company.

         In May 2005, the FASB issued Statement No. 154, Accounting Changes and
         Error Corrections--a replacement of APB Opinion No. 20 and FASB
         Statement No. 3. SFAS 154 replaces APB Opinion No. 20, Accounting
         Changes, and FASB Statement No. 3, Reporting Accounting Changes in
         Interim Financial Statements, and changes the requirements for the
         accounting for and reporting of a change in accounting principle. SFAS
         154 requires retrospective application to prior periods' financial
         statements of changes in accounting principle, unless it is
         impracticable to do so, in which case other alternatives are required.
         SFAS 154 is effective for accounting changes and corrections of errors
         made in fiscal years beginning after December 15, 2005, or for the
         Company's fiscal 2007 year end. The Company is currently evaluating the
         requirements of SFAS 154 and has not yet fully determined the impact,
         if any, on the consolidated financial statements.

         In June 2005, FASB issued FASB Staff Position ("FSP") SFAS No. 143-1,
         Accounting for Electronic Equipment Waste Obligations, to address the
         accounting for obligations associated with the European Union Directive
         on Waste Electrical and Electronic Equipment ("the Directive"). The
         Directive concludes that commercial users are obligated to retire, in
         an environmentally sound manner, specific assets that qualify as
         historical waste. The FSP requires capital treatment for this
         obligation and is to be adopted on the later of the first reporting
         period ending after June 8, 2005 or the date of adoption of the law by
         the applicable EU-member country. The Directive is currently under
         review in the United Kingdom and is expected to be transposed into U.K.
         law in fiscal 2007. The Company will continue to evaluate the impact as
         the U.K. and other EU-member countries enact the legislation.

         In June 2005, EITF 05-2 The Meaning of "Conventional Convertible Debt
         Instrument" in Issue No. 00-19 was issued and is to be applied to new
         instruments entered into and instruments modified in periods beginning
         after June 29, 2005. The new EITF clarifies that instruments that are
         convertible into a fixed number of shares at the option of the holder,
         based on the passage of time or a contingent event, should be
         considered "conventional" for purposes of applying Issue 00-19. The
         EITF also clarifies that convertible preferred stock with a mandatory
         redemption date may qualify for the exception included in paragraph 4
         of Issue 00-19 if the economic characteristics indicate that the
         instrument is more akin to debt than equity. The Company is currently
         evaluating the requirements of EITF 05-2 and has not yet fully
         determined the impact, if any, on the consolidated financial
         statements.

         In February 2006, the FASB issued SFAS 155 Accounting for Certain
         Hybrid Financial Instruments, which eliminates the exemption from
         applying SFAS 133 to interests in securitized financial assets so that
         similar instruments are accounted for similarly regardless of the form
         of the instruments. SFAS 155 also gives entities the option of applying
         fair value accounting to certain hybrid financial instruments in their
         entirety if they contain embedded derivatives that would otherwise
         require bifurcation under SFAS 133. Under the new approach, fair value
         accounting would replace the current practice of recording fair value
         changes in earnings. The election of fair value measurement would be
         allowed at acquisition, at issuance, or when a previously recognized
         financial instrument is subject to a remeasurement event. Adoption is
         effective for all financial instruments acquired or issued after the
         beginning of an entity's first fiscal year that begins after September
         15, 2006. The Company is currently evaluating the requirements of SFAS
         155 and has not yet fully determined the impact, if any, on the
         consolidated financial statements.

w)       Comparative Figures

         Effective fiscal 2006, the Company revised its allocation of revenues
         and cost of revenues between product and service groups and as a result
         restated its 2005 consolidated financial statements, including
         comparative figures. The revision resulted in a reclassification of
         $23.8, $24.7 and $0.1 from product revenues to service revenues, and
         also resulted in a reclassification of $21.9, $20.4 and $0.1 from
         product cost of revenues to service cost of revenues for 2004, 2005 and
         the Transition Period respectively.


3.       RELATED PARTY TRANSACTIONS

         As at April 24, 2005, April 30, 2005 and April 30, 2006, amounts
         receivable from related parties were $0.7, $0.7 and $0.4, and amounts
         payable to related parties were $15.9, $14.0 and $24.2 respectively.
         Significant related party transactions with companies controlled by or
         related to Dr. Terence Matthews (the "Principal Shareholder"), not
         otherwise disclosed in the financial statements, include the following:

                                       13


         Disposal of manufacturing operations

         On August 31, 2001, the Company sold its manufacturing operations,
         comprising plant, equipment, workforce and certain liabilities to
         BreconRidge Manufacturing Solutions Corporation ("BreconRidge"), a
         company in which the Principal Shareholder holds a significant
         interest, for total net consideration of $5.0 in the form of long-term
         promissory notes receivable of $5.4 and promissory notes payable of
         $0.4. During fiscal 2004, BreconRidge vacated premises that had been
         subleased from the Company pursuant to the disposal of the
         manufacturing operations. It therefore became evident at that point
         that sublease income over the lease renewal period, which was
         originally included in the estimated loss on disposal, would no longer
         be realized. As a result, additional expenses of $0.6 and $3.4 were
         recorded in the fiscal 2004 and 2005 Consolidated Statements of
         Operations as an additional loss arising on the disposal activity. In
         fiscal 2006, a reversal of $0.9 was recorded against the loss to
         reflect the receipt of new information that had a favorable impact on
         operating cost assumptions and corresponding estimates.

         In connection with the disposal of the manufacturing operations, the
         Company entered into a supply agreement dated August 31, 2001 whereby
         BreconRidge will provide certain products and services under terms and
         conditions reflecting prevailing market conditions at the time the
         agreement was entered into. The term of the agreement is six years and
         will be, unless otherwise terminated, automatically renewed on the same
         terms and conditions for additional consecutive one-year periods. Under
         the terms of the supply agreement, BreconRidge is required to purchase
         the Company's raw material inventory, before turning to third party
         suppliers for raw material procurement. During fiscal 2006, the Company
         purchased $101.4 of products and services (2004 - $84.9; 2005 - $94.2;
         Transition Period - $1.8) and sold $0.4 of raw material inventory (2004
         - $2.7; 2005 - $0.9; Transition Period - $0.1) under this agreement. As
         of April 30, 2006, balances payable pursuant to this agreement amounted
         to $24.0 (April 24, 2005 - $17.1; April 30, 2005 - $15.4) and balances
         receivable pursuant to this agreement amounted to $0.7 (April 24, 2005
         - $1.6; April 30, 2005 - $1.7).

         Under the terms of the supply agreement, the Company is required to
         purchase from BreconRidge certain tools used in the manufacturing
         process. These manufacturing tools are capitalized as part of fixed
         assets and are depreciated over their estimated useful lives. During
         fiscal 2006, manufacturing tools purchased from BreconRidge amounted to
         $0.9 (2004 - $0.1; 2005 - $0.2; Transition Period - $nil).

         On August 31, 2001, the Company also entered into service agreements
         with BreconRidge to provide facilities management services for the
         period covering the term of the premise lease agreements, as well as
         human resource and information systems support services. Amounts
         charged to BreconRidge were equal to, and recorded as a reduction of,
         the costs incurred to provide the related services in the Consolidated
         Statements of Operations. During fiscal 2006, the Company provided
         services valued at $0.5 under these agreements (2004 - $3.3; 2005 -
         $1.0; Transition Period - $nil).

         Leased properties

         In March 2001 the Company and Brookstreet Research Park Corporation
         (formerly known as Mitel Research Park Corporation), a company
         controlled by the Principal Shareholder entered into a lease agreement
         for its Ottawa-based headquarter facilities, under terms and conditions
         reflecting prevailing market conditions at the time the lease was
         entered into. The lease agreement is for 10 years expiring in March
         2011.

         On August 31, 2001, the Company entered into sublease agreements with
         BreconRidge for certain office and manufacturing facilities in Ottawa
         and in the United Kingdom ("U.K.") under terms and conditions
         reflecting prevailing market conditions at the time the leases were
         entered into. The sublease agreement was amended on May 31, 2002 to
         increase leased space. The Ottawa sublease agreement is for a term of
         five years expiring on August 31, 2006. In August 2005, the building in
         the U.K. was sold to an unrelated third party. Accordingly, the Company
         no longer receives rental income from BreconRidge for facilities under
         the U.K. sublease agreement.

         See Note 17 for disclosure of related party rental expense, sublease
         income, committed future minimum lease payments and future sublease
         income. As of April 30, 2006, balances due to the company controlled by
         the Principal Shareholder and related to the lease agreement amounted
         to $0.4 (April 24, 2005 - insignificant; April 30, 2005 -
         insignificant).

         Financing

         During fiscal 2003, the Company borrowed funds to finance its
         operations from Wesley Clover Corporation, a company controlled by the
         Principal Shareholder. The loans bore interest at prime and the
         interest expense incurred on these related party loans amounted to $0.6
         and $0.7 in fiscal 2003 and 2004, respectively.

                                       14



         Other

         In September 2001, the Company entered into a strategic alliance
         agreement and a global distribution agreement with March Networks
         Corporation ("March Networks"), a company controlled by the Principal
         Shareholder, to broaden its product portfolio and its distribution
         channel. Under the terms of the agreement, the parties agree to
         cooperate in the performance of joint development activities and each
         party will bear its own costs arising in connection with the
         performance of its obligations. Both parties will share common costs
         incurred in the performance of joint activities. During fiscal 2006,
         the Company purchased $0.3 of products and services (2004 - $1.0; 2005
         - $0.4; Transition Period - $nil) from March Networks and had a balance
         payable recorded in the due to related parties pursuant to this
         agreement in the amount of $0.1 (April 24, 2005 - insignificant; April
         30, 2005 - insignificant).

         Other sales to and purchases from companies related to the Principal
         Shareholder and arising in the normal course of the Company's business
         were $0.4 and $3.9 respectively for the year ended April 30, 2006 (2004
         - $0.3 and $0.7, respectively; 2005 - $0.4 and $1.2, respectively;
         Transition period - insignificant). The net balances payable as a
         result of these transactions was $0.8 at April 30, 2006 (April 24, 2005
         - $0.3; April 30, 2005 - $nil).


4.       SPECIAL CHARGES

         During fiscal 2004, the Company implemented workforce reduction
         programs in an effort to realign spending levels with the lower sales
         volumes. Accordingly, pre-tax special charges of $11.7, net of
         reversals of prior year's charges of $0.3, were recorded in fiscal
         2004. The components of the fiscal 2004 charges include $8.5 of
         employee severance and benefits and associated legal costs incurred in
         the termination of 196 employees throughout the world, $3.2 of
         non-cancelable lease costs related to excess facilities and $0.3 of
         loss on disposal of capital assets. The lease termination obligation
         will be reduced over the remaining term of the leases, which range from
         one year to ten years. Accordingly, the long-term portion of lease
         termination obligation has been recorded under long term liabilities.

         During fiscal 2005 the Company recorded pre-tax special charges of
         $10.6. The components of the charge include $8.7 of employee severance
         and benefits incurred in the termination of 154 employees around the
         world, $1.3 of non-cancelable lease costs related to excess facilities,
         $0.9 of assets written off as a result of the Company's discontinuation
         of its ASIC design program, and a reversal of prior year's charges of
         $0.3. The lease termination obligations incurred in prior fiscal years
         will be reduced over the remaining term of the leases, which range from
         one year to nine years. Accordingly, the long-term portion of lease
         termination obligation has been recorded under long term liabilities.

         During fiscal 2006 the Company implemented additional restructuring
         actions which resulted in pre-tax special charges of $5.7. The
         components of the charge include $5.7 of employee severance and
         benefits incurred in the termination of 84 employees around the world,
         $0.8 of accreted interest related to lease termination obligation and a
         reversal of $0.8 related to a new sublease of a facility previously
         provided for in special charges. Payment of the workforce reduction
         liabilities is expected to be complete within the next twelve months.
         The lease termination obligation incurred in prior fiscal years
         continues to be reduced over the remaining term of the leases.
         Accordingly, a balance of $3.1 representing the long-term portion of
         the lease obligation has been recorded under long term liabilities.

5.       SEGMENT INFORMATION

         General description

         Mitel's portfolio of solutions provide advanced voice, video and data
         communications platforms, desktop phones and Internet appliances,
         applications for customer relationship management and mobility,
         messaging and multimedia collaboration.

         In previous years, the Company reported its operations in two segments:
         the Communications Solutions segment ("Solutions") and the Customer
         Services segment ("Services"). Effective fiscal 2006, Mitel changed its
         structure of reporting so that the reportable segments are now
         represented by the following four geographic areas: United States,
         Canada and Caribbean & Latin America (CALA), Europe, Middle East &
         Africa (EMEA), and Asia Pacific. These reportable segments were
         determined in accordance with how management views and evaluates the
         Company's business. The results of operations for 2005 and 2004 have
         been restated to conform with the new presentation.

         The Company's Chief Executive Officer ("CEO") has been identified as
         the chief operating decision maker as defined by SFAS No. 131,
         Disclosures about Segments of an Enterprise and Related Information.
         The CEO evaluates the performance of the segments and allocates
         resources based on information provided by the Company's internal
         management system. The primary financial measure used by the CEO is the
         contribution margin, which includes segment revenues less the related
         cost of sales and direct selling costs. The Company does not allocate
         research and development, marketing, general and administrative
         expenses, amortization, stock-based compensation expense and one-time
         charges to its segments as management does not use this information to
         measure the performance of the operating segments. These unallocated
         expenses are included in shared and unallocated costs in the
         reconciliation of operating results. In addition, total asset
         information by segment is not presented because the CEO does not use
         such segmented measures to allocate resources and assess performance.
         Inter-segment sales are based on fair market values and are eliminated
         on consolidation. With the exception of contribution margin defined
         above, the accounting policies of reported segments are the same as
         those described in the summary of significant accounting policies.

         Concentrations

         The Company sells its products and services to a broad set of
         enterprises ranging from large, multinational enterprises, to small and
         mid-sized enterprises, government agencies, health care organizations
         and schools. Management believes that the Company is exposed to minimal
         concentration risk since the majority of its business is conducted with
         companies within numerous industries. The Company performs periodic
         credit evaluations of its customers' financial condition and generally
         does not require collateral for its accounts receivable. In some cases,
         the Company will require payment in advance or security in the form of
         letters of credit or third-party guarantees. No single customer
         accounted for more than 10 percent of the Company's revenue for the
         periods ended April 25, 2004, April 24, 2005, Transition Period and
         April 30, 2006.

         As a result of the disposal of the manufacturing operations described
         in Note 3, BreconRidge manufactures substantially all of the Company's
         products. The Company is not obligated to purchase products from
         BreconRidge in any specific quantity, except as the Company outlines in
         forecasts or orders for products required to be manufactured by
         BreconRidge. In addition, the Company may be obligated to purchase
         certain excess inventory levels from BreconRidge that could result from
         the Company's actual sales of product varying from forecast. As of
         April 30, 2006, there was excess inventory of $0.9 (2005 - $0.6;
         Transition Period - $0.6) for which the Company was liable, and has
         been recorded in the due to related parties amount. The Company's
         supply agreement with BreconRidge results in a concentration that, if
         suddenly eliminated, could have an adverse effect on the Company's
         operations. While the Company believes that alternative sources of
         supply would be available, disruption of its primary source of supply
         could create a temporary, adverse effect on product shipments.

         Sale of Edict Training Ltd.

         On October 7, 2005, the Company completed the sale of its 8,000 shares,
         or eighty-percent ownership interest, in Edict for consideration of
         (pound)0.2, or $0.3 to be applied against amounts due from Edict
         Training Ltd. The transaction resulted in an


                                       18


         insignificant loss, which was recorded in other income/expense. As a
         result of this transaction, the Company no longer holds any equity
         interest in Edict. The costs incurred in connection with this

         Sale of U.K. land and building

         On August 31, 2005, the Company sold land and building relating to its
         U.K. subsidiary for cash consideration of $12.4 ((pound)7.1), resulting
         in a pre-tax gain of $7.3 ((pound)4.2). The transaction included a
         commitment for the Company to lease back a portion of the property,
         which provided the Company with more than a minor part but less than
         substantially all of the use of the property, and thereby qualified the
         transaction as a sale-leaseback arrangement under SFAS 13. As a result,
         the Company entered into a 6-month interim lease and a 10-year
         long-term lease for a portion of the property sold. Accordingly, $5.8
         of the gain has been deferred and will be amortized over the combined
         term of the leases (10 1/2 years). The remaining gain of $1.5 was
         recognized immediately at the time of the sale and included in gain on
         sale of assets. The deferred and unamortized balance at April 30, 2006
         was $5.5. Provision for income taxes relating to the sale of the land
         and buildings was $1.0 ((pound)0.6).


7.       SECURITIZATION OF ACCOUNTS RECEIVABLE

         On April 16, 2004, the Company entered into a Receivables Purchase
         Agreement (the "Agreement"). Under the Agreement, the Company may sell
         up to $38.9 of non-interest bearing trade accounts receivable to an
         unaffiliated financial institution on a revolving basis. The Company
         retains an interest in the transferred accounts receivable equal to the
         amount of the required reserve amount and continues to service,
         administer and collect the pool of accounts receivable on behalf of the
         purchaser and receives a fee for performance of these services. The
         Company's interest in collections is subordinated to the purchasers'
         interest.

         Effective December 1, 2004 the Company was not in compliance with
         certain covenants required under the terms of the facility and ceased
         to sell receivables into the facility. As of April 24, 2005, April 30,
         2005 and April 30, 2006, the outstanding balance of the securitized
         receivables, the interest retained by the Company in the transferred
         receivables, and the servicing liability outstanding were all $nil.

         For fiscal 2005, Transition Period, and fiscal 2006, the Company
         recognized a pre-tax loss of $0.3, $nil and $nil respectively relating
         to the sale of receivables. There were no securitized receivables
         outstanding at the end of each of the three periods.

         The table below outlines the proceeds received from and amounts paid to
         the securitization trust for the periods ended April 24, 2005, April
         30, 2005 and April 30, 2006:

         Amortization of intangible and other assets was $0.2, $0.7, $nil and
         $1.7 each of fiscal 2004, fiscal 2005, Transition Period and fiscal
         2006, respectively. Deferred debt issue costs will be amortized over 5
         years of which $0.8 has been amortized to date. The estimated
         amortization expense related to intangible assets in existence as of
         April 30, 2006, over the next five years is as follows: fiscal 2007-
         $2.0; fiscal 2008 - $2.0; fiscal 2009 - $1.6; fiscal 2010 - $1.0; and
         fiscal 2011 - $nil. The Company does not allocate intangible assets to
         its segments, as management does not use this information to measure
         the performance of the operating segments.


13.      BANK INDEBTEDNESS

         As of April 24, 2005, the Company had a 364 day revolving credit
         facility of $20.3 (C$25.0) that was repaid in full on April 27, 2005
         and cancelled as at that date. The facility bore interest at the prime
         rate or US base rate plus 1.5 percent or LIBOR or Bankers' Acceptances
         plus 2.5 percent, with interest payable monthly, and was secured by a
         general assignment of substantially all the Company's accounts
         receivable and a general security interest in the remaining assets of
         the Company. The credit facility was also personally guaranteed by the
         Principal Shareholder. The credit facility was to mature on June 30,
         2005 and contained certain restrictions and financial covenants. The
         Company was not in compliance with certain of these financial covenants
         during the year ended April 24, 2005, however the bank provided a
         consent and waiver of the non-compliance for those financial covenants.
         As at April 24, 2005, the Company was in compliance with these
         financial covenants. As of April 24, 2005, the Company had outstanding
         cash borrowings of $15.8 under this facility and $0.8 was committed
         under letter of credit arrangements.

         As of April 30, 2006, the Company's U.K. subsidiary has indemnity
         facilities totaling $1.8 ((pound)1.0) available for letters of credit
         and other guarantees, $0.8 of which has been drawn (April 30, 2005 -
         $0.9). The indemnity and credit facilities are unsecured. On January
         31, 2006, the Company cancelled its overdraft facility (April 30, 2005
         - $1.9).

         Amounts appearing in bank indebtedness as of April 30, 2005 and April
         30, 2006 represent credit book balances resulting from an excess of
         outstanding checks over funds on deposit where a right of offset does
         not exist.

         Pursuant to the terms of the building mortgage agreement, the Company's
         U.K. subsidiary must comply with certain financial covenants. At April
         24, 2005 and April 30, 2005 the subsidiary was in compliance with these
         financial covenants. The mortgage loan was repaid and cancelled in
         August 2005 following the sale of the U.K. land and building, as
         described in Note 6.

         Interest expense related to long-term debt, including obligations under
         capital leases, was $0.5 in fiscal 2006 (2004 - $1.3; 2005 - $1.0;
         Transition Period - insignificant). Future minimum lease payments as of
         April 30, 2006 under capital leases total $4.5 of which $1.8, $1.7,
         $1.0 and $nil relate to fiscal years 2007 to 2010, respectively.
         Interest costs of $0.4 are included in the total future lease payments.


16.      CONVERTIBLE NOTES

         Senior Secured Convertible Notes

         On April 27, 2005, the Company issued Senior Secured Convertible Notes,
         with attached warrants, for gross proceeds of $55.0 to a group of
         private investors ("Holders"). The notes mature on April 28, 2010 and
         accrue interest, payable semi-annually in arrears, at LIBOR plus 5.0%
         for any period prior to the consummation of a Qualified IPO, LIBOR plus
         2.5% for any period following the consummation of a Qualified IPO and
         LIBOR plus 10.0% on or after the 30 month anniversary of the issuance
         date of the convertible notes if a Qualified IPO has not been
         consummated. At any time on or after the consummation of a Qualified
         IPO or upon the occurrence of a Fundamental Change, the Holders of the
         notes are entitled to convert any portion of the outstanding principal
         and accrued and unpaid interest into common shares of the Company with
         the number of common shares to be received being calculated based on a
         formula that considers the fair value of the common shares in the case
         of an IPO and, in the case of a fundamental change, is based on $1.50
         per common share subject to adjustment for a Make-Whole Premium. The
         Make-Whole Premium, which is based on the effective date of the
         Fundamental Change, the current fair value of the Company's common
         shares and whether the Fundamental Change occurs Pre-IPO or Post-IPO
         may be settled in cash, by delivery of common shares or a combination
         thereof at the option of the Company. The determination of the
         Make-Whole Premium is not based on interest rates or credit risk and
         therefore is not considered clearly and closely related to the host
         instrument and qualifies as an embedded derivative under SFAS 133.
         Accordingly, the fair value of the embedded derivative is required to
         be recorded at fair value separate from the debt host. As at April 30,
         2006 management has determined the fair value of the derivative
         instrument to be nominal.

         At any time commencing on or after the later of (i) May 1, 2008 and
         (ii) the 18 month anniversary of the Lock-Up Expiration Date provided
         that on each of the 10 consecutive trading days, the closing sale price
         per share is at least 200% of the conversion price of the notes, the
         Company has the right to redeem all or any portion of the principal
         remaining under the notes at a redemption price equal to the principal
         plus interest accrued to the date of redemption plus the net present
         value of the remaining interest payments to April 28, 2010. In the
         Event of Default, Holders of the notes may accelerate and require the
         Company to redeem all or any portion of the notes held including
         accrued and unpaid interest. Upon the occurrence of a Fundamental
         Change, the Company shall irrevocably offer to repurchase all or a
         portion of the note at a price equal to (i) 125% of the principal of
         the notes (plus accrued and unpaid interest) if the Fundamental Change
         occurs during 18 months after issuance but prior to the consummation of
         a Qualified IPO, (ii) 120% of the principal of the notes (plus accrued
         and unpaid interest) if the Fundamental Change occurs following the 18
         months after issuance but prior to the consummation of a Qualified IPO
         or (iii) 100% of the principal of the notes (plus accrued and unpaid
         interest) if the Fundamental Change occurs following the consummation
         of a Qualified IPO. A Fundamental Change includes a consolidation or
         merger, sale, transfer or assignment of all or substantially all of the
         Company's assets, a purchase of more than 50% of the Company's
         outstanding common shares, consummation of a stock purchase agreement
         or other business combination, or reorganization, recapitalization or
         reclassification of the common shares of the Company, or any event that
         results in the Principal Shareholder beneficially owning in aggregate
         less than 115 million of the issued and outstanding shares in the
         capital of the Company.

                                       22


         As a redemption upon the occurrence of a fundamental change, prior to
         the consummation of a Qualified IPO could result in (1) the Holder
         doubling its initial rate of return on the debt host and (2) the rate
         of return is at least twice what would otherwise be the market return
         for a contract that has the same terms and credit risk as the debt host
         contract, the redemption feature is not considered to be clearly and
         closely related to the debt host and requires separate accounting from
         the debt host under the provisions of FAS 133. At April 30, 2006
         management has assigned nominal value to the derivative instrument.

         The Holders of the notes have no voting rights and all payments due
         under this note shall rank pari passu with all additional notes and,
         prior to the consummation of a Qualified IPO, shall not be subordinate
         to any indebtedness of the Company. The notes are secured by a first
         priority, perfected security interest over the assets of the Company
         and over the assets and stock of specific subsidiaries.

         In conjunction with the issuance of the Senior Secured Convertible
         notes, the Company issued 16.5 million warrants, which are described
         further in Note 21. The gross proceeds from the financing were
         allocated between the notes and the warrants based on their relative
         fair values. Debt issue costs of $4.5 were incurred in connection with
         the financing transaction, and have been recorded as a deferred charge
         within the Intangible and Other Assets balance in the Consolidated
         Balance Sheet.

         The following table summarizes the allocation of the convertible notes
         among its different elements and movement in the carrying value of the
         convertible notes:

         Convertible Debentures

         On August 16, 2002, the Company closed a private offering of debentures
         convertible into shares of the Company that resulted in total cash
         proceeds of $6.5. The maturity date of the convertible debentures was
         July 27, 2003 and was extended to October 31, 2003 during fiscal 2004.
         The debentures provided for interest to accrue at the rate of 6.5% per
         annum payable on the maturity date or upon conversion of the debentures
         and accrued interest into common shares of the Company.

         On October 31, 2003 the Company reached an agreement with the debenture
         holders whereby the entire carrying value of the debentures of $8.3 was
         converted to 5,445,775 common shares of the Company at C$2.00 per
         common share. As the conversion price was lower than the fair market
         value of the Company's common shares of C$2.75 per share on the
         commitment date (August 16, 2002), a beneficial conversion feature was
         triggered resulting in a non-cash expense of $3.1 recorded in the
         fiscal 2004 Consolidated Statements of Operations.

         In April 2004, 5,081,619 of the common shares issued upon conversion of
         the debentures were exchanged for 10,163,238 Series B Preferred Shares
         of the Company. During fiscal 2005, the remaining 364,156 common shares
         issued to the convertible debenture holders upon conversion were
         exchanged for 728,312 Series B Preferred Shares. As the Company
         determined that the fair value of the Series B preferred shares to be
         equivalent to the fair value of the common shares, there was no gain or
         loss recorded on the exchange.

         are $nil (2005 - $0.1; Transition Period - $nil).

         Guarantees

         The Company has the following major types of guarantees that are
         subject to the accounting and disclosure requirements of FASB
         Interpretation No. 45, Guarantor's Accounting and Disclosure
         Requirements for Guarantees, Including Indirect Guarantees of
         Indebtedness of Others ("FIN 45"):

         Product warranties:

         The Company provides all customers with standard warranties on hardware
         and software for periods up to fifteen months. Customers can upgrade
         the standard warranty and extend the warranty up to five years on
         certain products. The following table details the changes in the
         warranty liability:

         Intellectual property indemnification obligations:

         The Company enters on a regular basis into agreements with customers
         and suppliers that include limited intellectual property
         indemnification obligations that are customary in the industry. These
         guarantees generally require the Company to compensate the other party
         for certain damages and costs incurred as a result of third party
         intellectual property claims arising from these transactions. The
         nature of these intellectual property indemnification obligations
         prevents the Company from making a reasonable estimate of the maximum
         potential amount it could be required to pay to its customers and
         suppliers. Historically, the Company has not made any significant
         indemnification payments under such agreements and no amount has been
         accrued in the consolidated financial statements with respect to these
         guarantees.

                                       24


         Bid and performance related bonds:

         The Company enters into bid and performance related bonds related to
         various customer contracts. Performance related bonds usually have a
         term of twelve months and bid bonds generally have a much shorter term.
         Potential payments due under these may be related to the Company's
         performance and/or the Company's resellers' performance under the
         applicable contract. Under FIN 45, the Company must measure and
         recognize a liability equal to the fair value of bid and performance
         related bonds involving the performance of the Company's resellers. At
         April 24, 2005, April 30, 2005 and April 30, 2006 the liability
         recognized in accounts payable and accrued liabilities related to these
         bid and performance related bonds, based on past experience and
         management's best estimate, was insignificant. At April 30, 2006, the
         total maximum potential amount of future payments the Company could be
         required to make under bid and performance related bonds was $2.5 (2005
         - $5.3; Transition Period - $5.4).


18.      CONTINGENCIES

         The Company is party to a small number of legal proceedings, claims or
         potential claims arising in the normal course of its business. In the
         opinion of the Company's management and legal counsel, any monetary
         liability or financial impact of such claims or potential claims to
         which the Company might be subject after final adjudication would not
         be material to the consolidated financial position of the Company, its
         results of operations, or its cash flows.


19.      REDEEMABLE COMMON SHARES

         Pursuant to the shareholders' agreement dated April 23, 2004, upon
         failure to complete an initial public offering ("IPO") of its common
         shares by September 1, 2006 (the "put date"), Zarlink, a shareholder of
         the Company, has a right to require the Company to redeem for cash all
         or part of its 10,000,000 common shares held in the Company at a price
         of C$2.85 per common share. The put date has subsequently been deferred
         to May 1, 2007 (see note 28) Accordingly, the common shares held by
         Zarlink with an original carrying value of $16.9 are classified in the
         mezzanine section of the Consolidated Balance Sheets as redeemable
         common shares. In addition, an aggregate amount of $1.8 (2005 - $1.3;
         Transition Period - $1.3) accreted for the excess of the redemption
         amount over the original carrying value was recorded as of April 30,
         2006. The accreted amount is recorded as an increase in accumulated
         deficit.

         On April 23, 2004 another shareholder holding 4,000,000 redeemable
         common shares of the Company reached an agreement with the Company
         whereby all 4,000,000 redeemable common shares were exchanged for
         16,000,000 Class B Series 1 Convertible and Redeemable Preferred Shares
         ("Series B Preferred Shares") of the Company at their then fair value
         of C$1.00 per preferred share. As a result of the exchange, the
         carrying value of the redeemable common shares of $12.5, including
         accreted interest, was reclassified from redeemable common shares to
         convertible, redeemable preferred shares, all within the mezzanine
         section of the Consolidated Balance Sheets.

         The following table summarizes the changes in redeemable common shares
         during the years presented:

20.      CONVERTIBLE, REDEEMABLE PREFERRED SHARES

         Series A Preferred Shares

         On April 23, 2004 the Company issued 20,000,000 Class A Series 1
         Convertible and Redeemable Preferred Shares ("Series A Preferred
         Shares") for cash consideration of C$1.00 per share (USD equivalent of
         $0.73 per share), together with attached common stock purchase
         warrants. As described further in Note 21, the warrants entitle the
         Series A holders to purchase 5,000,000 common shares of the Company at
         an exercise price of C$1.25 per share. The warrants are immediately
         exercisable and expire 7 years from the original issuance date. The
         fair value of the warrants on the date of issuance of $1.0 was
         allocated from the net proceeds on sale of the shares and is recorded
         as a component of shareholders' deficiency.

         The Series A Preferred Shares are subject to non-cumulative dividends
         as and when declared by the Board of Directors of the Company. The
         amount, if any, of any such dividends is at the absolute discretion of
         the Board. No dividends have been declared as of April 24, 2005, April
         30, 2005 and April 30, 2006. The holders of the Series A Preferred
         Shares are entitled to elect two members of the Board of Directors of
         the Company, and at least one of the members of certain committees of
         the Board of Directors, and are entitled to vote as a single class with
         each share of Series B Preferred Shares and Common Shares.

                                       25


         The Series A Preferred Shares are convertible at any time at the option
         of the holders without payment of any additional consideration into
         common shares at a conversion value of C$1.00 per share, plus any
         declared but unpaid dividends. The terms of the agreement provide that,
         if the Company subsequently issues common shares or common share
         equivalents at a price less than the conversion value in effect prior
         to such issuance (subject to certain excluded transactions), the
         conversion value of the Series A Preferred Shares will be reduced
         accordingly. The Series A Preferred Shares also have the following
         additional conversion features: i) the shares will automatically
         convert into common shares upon the closing of a qualified IPO or upon
         a vote or written consent of the majority of the Series A shareholders;
         ii) if the Series A shareholders convert after 2 years from the
         original issue date, in addition to the common shares otherwise
         issuable upon conversion, the Series A shareholders will also receive,
         in respect of each share so converted, an additional number of common
         shares equal to the issue price of C$1.00 per preferred share divided
         by the fair market value of a common share on the date of conversion
         iii) if the shares are converted pursuant to a non-qualified IPO within
         the first two years after the original issuance, the Series A
         shareholders will receive an additional number of common shares based
         on a formula set out in the articles of the Company which takes into
         consideration the relative value of the issue price to the IPO price.
         As the fair market value of the common shares into which the Series A
         Preferred Shares were convertible was greater than the effective
         conversion price for accounting purposes, determined based on the gross
         proceeds less the fair value of the warrants on the date of issuance, a
         deemed dividend for this excess of $1.4 was recorded as an increase in
         the net loss attributable to common shareholders for the year ended
         April 25, 2004.

         At any date after 5 years from the original issuance date, or at any
         date prior to a partial sale event other than a public offering, the
         majority holders of the Series A Preferred Shares have a right to
         require the Company to redeem the shares for cash. The redemption
         amount is equal to the original issue price of C$1.00 per preferred
         share times the number of Series A Preferred Shares outstanding, plus
         any declared but unpaid dividends, plus the then current fair market
         value of the common shares into which the Series A Preferred Shares are
         convertible (other than common shares issuable under additional
         conversion features). The Series A shareholders will also have a right
         to request the redemption of the Series A shares upon the exercise of
         put rights by certain shareholders. In the event of an exercise of put
         rights, the redemption amount will be equal to the original issue price
         of C$1.00 per preferred share times the number of Series A Preferred
         Shares outstanding, plus any declared but unpaid dividends, plus the
         issuance of the number of common shares into which the Series A
         Preferred Shares are convertible. At April 24, 2005, April 30, 2005 and
         April 30, 2006 management has estimated that the fair market value of
         the preferred shares was C$1.00, C $1.00 and C$2.55 per share,
         respectively.

         As a portion of the redemption price of the preferred shares is indexed
         to the common share price of the Company, an embedded derivative exists
         which has been bifurcated and accounted for separately, under SFAS 133.
         The derivative component relating to the Series A Preferred Shares was
         valued at $17.3 as of April 30, 2006 (April 24, 2005 - $8.7; April 30,
         2005 - $8.6), and is recorded as a liability with the change in the
         value of the derivative being recorded as a non-cash expense in the
         Consolidated Statements of Operations. The initial value of the Series
         A Preferred Shares of $5.8, after allocation of proceeds between
         warrants and the derivative instrument, is classified in the mezzanine
         section of the Consolidated Balance Sheet. The difference between the
         initial carrying amount and the redemption amount is being accreted
         over the five-year period to redemption. For fiscal 2005, Transition
         Period and fiscal 2006, the amount of accreted interest was $1.2,
         insignificant and $1.6, respectively.

         Series B Preferred Shares

         On April 23, 2004, pursuant to the issuance of the Series A Preferred
         Shares, certain common shareholders of the Company exchanged 29,530,494
         common shares for 67,060,988 Series B Preferred Shares of the Company
         at C$1.00 per preferred share. During fiscal 2005, the remaining
         364,156 common shares issued to the convertible debenture holders
         (refer to Note 16) upon conversion were exchanged for 728,312 Series B
         preferred shares.

         The Series B Preferred Shares carry the same rights and privileges with
         respect to dividends and votes as the Series A Preferred Shares, except
         that the Series B Preferred Shares rank junior to the Series A
         Preferred Shares, but senior to the holders of common shares or any
         other class of shares, in the event of payment of preferential amounts
         required upon a liquidation or change of control.

         The Series B Preferred Shares carry the same conversion rights, and in
         the same conversion amounts, as the Series A Preferred Shares.

         Pursuant to the shareholders' agreement dated April 23, 2004, upon
         failure to complete an IPO of its common shares by the put date, one of
         the Company's Series B Preferred Shareholders, has a right to require
         the Company to redeem for cash all or part of its 16,000,000 Series B
         Preferred Shares held in the Company at a price of C$1.00 per preferred
         share, plus interest accrued at an annual rate of 7 percent commencing
         on August 31, 2001 and compounded semi-annually. The put date has been
         subsequently deferred to May 1, 2007 (see note 28).

         At any date after 5 years from the original issuance date, or at any
         date prior to a partial sale event other than a public offering, the
         majority holders of the Series B Preferred Shares have a right to
         require the Company to redeem the shares for cash. The redemption
         amount is equal to the original issue price of C$1.00 per preferred
         share times the number of Series B Preferred Shares outstanding, plus
         any declared but unpaid dividends, plus the then current fair market
         value of the common shares into which the Series B Preferred Shares are
         convertible (other than common shares issuable under additional
         conversion features). At April 24, 2005, April 30, 2005 and April 30,
         2006 management has estimated that the fair market value of the
         preferred shares was C$1.00, C $1.00 and C$2.55 per share,
         respectively.

                                       26


         As a portion of the redemption price of the preferred shares is indexed
         to the common share price of the Company, an embedded derivative exists
         which has been bifurcated and accounted for separately, under SFAS 133.
         The derivative component relating to the Series B Preferred Shares was
         valued at $58.6 as of April 30, 2006 (April 24, 2005 - $29.3; April 30,
         2005 - $28.8) and is recorded as a liability. The initial value of the
         Series B Preferred Shares of $27.7, after allocation of proceeds to the
         derivative instrument, was classified in the mezzanine section of the
         Consolidated Balance Sheet. The difference between the initial carrying
         amount and the redemption amount is being accreted over the five-year
         period to redemption. For fiscal 2005, Transition Period and fiscal
         2006, the amount of accreted interest was $4.0, $0.1 and $4.8,
         respectively. Similar to the Series A Preferred Shares, the derivative
         component relating to the Series B Preferred is recorded as a liability
         with the change in the value of the derivative being recorded as a
         non-cash expense in the Consolidated Statements of Operations.

         The following table summarizes the allocation of the convertible,
         redeemable preferred shares, net of share issue costs, among its
         different elements:

         i) During fiscal 2003, the Company, in conjunction with the Partner
         Company and the Funding Company, signed an agreement for funding from
         the Canadian Government for up to C$60.0 of the Funding Company's, the
         Partner Company's and the Company's research and development activities
         over a three-year period. Pursuant to the terms of the agreement, in
         exchange for funding received from the Government of Canada, the
         Company has committed to issue warrants to Her Majesty the Queen in
         Right of Canada exercisable into common shares for no additional
         consideration. The number of warrants to be issued on September 30 in
         each of fiscal year was determined based on the funding received and
         the fair market value of the common shares at the date of issuance. The
         warrants have no expiry date.

         As at April 25, 2004 the Company had issued warrants to acquire
         12,986,968 common shares pursuant to the above agreement. During
         fiscal 2005, an additional 13,862,943 warrants were issued at the
         then fair value of C$1.00 per share, of which 11,481,109 warrants
         related to $8.7 of government funding that was receivable and
         received during fiscal 2004, and the remaining 2,381,834 relate to
         funding received during fiscal 2005. As at April 24, 2005 a total
         of 26,849,911 warrants had been issued pursuant to the above
         agreement. Warrants relating to the $7.2 of government funding
         received in fiscal 2005 were issued in fiscal 2006 in


                                       27


         accordance with the terms of the agreement. Since the Company had
         reached its maximum funding limit in fiscal 2005, no additional
         funding was received and no additional warrants were issued in
         fiscal 2006. The remaining $1.3 of government funding recorded in
         fiscal 2005 continues to be receivable at April 30, 2006.

         ii) In connection with the issuance of Series A Preferred Shares in
         fiscal 2004, the Company issued to the holders of the Series A
         Preferred Shares warrants to acquire 5,000,000 common shares of the
         Company. The warrants are exercisable at C$1.25 per common share and
         have a seven year life. The warrants were valued using the
         Black-Scholes option pricing model with the following assumptions:
         seven year life, interest rate of 4.37 percent, volatility of forty
         percent and no dividends. The warrants are automatically exercisable
         based on a formula in connection with a Qualified IPO.

         iii) In connection with the issuance of Series A Preferred Shares in
         fiscal 2004, the Company issued warrants to the placement agent to
         acquire 1,000,000 common shares of the Company, as consideration for
         services rendered in connection with the financing transaction and
         accounted for them as an issue cost. The fair value of the warrants was
         estimated based on the fair value of services received. The warrants
         are exercisable at C$1.00 per share and have a five year life. The
         warrants expire in connection with a Qualified IPO.

         iv) As described in Note 16, in connection with the issuance of the
         Senior Secured Convertible Notes on April 27, 2005, the Company issued
         to the holders warrants to acquire 16,500,000 common shares of the
         Company. The warrants are exercisable at any time on or after the
         earliest of the date of effectiveness of a Qualified IPO, the date of
         effectiveness of any other public offering of the common shares or upon
         and following a fundamental change. The warrants are exercisable at a
         price per share equal to the lower of (i) USD $1.50 and (ii) the
         arithmetic average of the closing sales prices of the Company's shares
         during the first 10 trading days following the date of expiry of any
         lock-up restrictions entered into by the Company in connection with a
         Qualified IPO. The warrants expire the later of (i) the 4th anniversary
         of the issuance date and (ii) if a Qualified IPO occurs prior to the
         4th anniversary, the 1st anniversary of the effective date of the
         Qualified IPO. The Holder may elect, in lieu of making the cash payment
         upon exercise of the warrants, to receive the "net number" of common
         shares which equates to the excess of the fair value of the common
         shares over its exercise price. The relative fair value of the warrants
         on the date of issuance of $7.7 was allocated from the proceeds on the
         issuance of the convertible notes and has been recorded as a component
         of shareholders' deficiency. The warrants were valued using the
         Black-Scholes option pricing model with the following assumptions: five
         year life, interest rate of 3.83 percent, volatility of one hundred
         percent and no dividends.


22.      SHARE CAPITAL

         The Company's authorized capital stock consists of an unlimited number
         of common shares, and an unlimited number of Series A Preferred Shares
         and Series B Preferred Shares. The holders of common shares are
         entitled to one vote per share and are entitled to dividends when and
         if declared by the Board of Directors. The terms of the preferred
         shares are described further in Note 20 of these financial statements.

         During fiscal 2006, the Company issued 132,261 shares (2004 - 33,591;
         2005 - 153,616) for total consideration of $0.1 (2004 - $0.1; 2005 -
         $0.1) in the form of professional services received. The carrying value
         of the shares represents the fair market value of the services
         received.

         Equity offerings

         On June 8, 2001, February 15, 2002 and on February 28, 2002, the
         Company completed three equity offerings to certain employees and
         eligible investors. The Company issued 5,606,180 common shares for
         total consideration of $14.6, of which $8.8 was received in cash and
         $5.9 was covered by employee interest-free loans repayable to the
         Company over a two-year period from the date of each offering. The
         repayment of certain of the loans was suspended during fiscal 2003 and
         reinstated during fiscal 2004.

         During fiscal 2005 the Company completed an equity offering to certain
         employees and eligible investors. The Company issued 5,601,870 common
         shares at C$1.00 per share, for total consideration of $4.6, of which
         $3.0 was received in cash and $1.6 was covered by employee
         interest-free loans repayable to the Company over a maximum two-year
         period from the date of the offering.

         Share Purchase Loans

         As part of the fiscal 2005 equity offering described above, the Company
         implemented an Employee Stock Purchase Plan allowing US employees to
         purchase up to 2,000,000 common shares of the Company through a single
         lump sum payment and/or a Company loan. Shares purchased using company
         loans are secured by the underlying share, repayable by means of
         payroll deduction over a maximum two year period and non-interest
         bearing unless there is a default in payment, in which case the loan
         bears simple interest calculated at 10% per annum. Non-US employees
         were provided with the ability to acquire shares under similar terms
         and conditions. As of April 24, 2005 and April 30, 2005, outstanding
         employee share purchase loans receivable, in the amount of $1.2 and
         $1.2 respectively were recorded against shareholders' deficiency.
         Repayments against the loans were made during fiscal 2006 and the
         balance remaining at April 30, 2006 was $0.3.

         Stock Option Plan

         In March 2001, the Company's shareholders approved the Mitel
         Networks Corporation Employee Stock Option Plan (the "Plan")
         applicable to the Company's employees, directors, consultants
         and suppliers and authorized 25,000,000 shares for issuance


                                    28


         thereunder. The options are granted at no less than the fair
         market value of the common shares of the Company on the date of
         grant and may generally be exercised in equal portions during the
         years following the first, second, third and fourth anniversaries
         of the date of grant, and expire on the earlier of the fifth
         anniversary and termination of employment. The number of common
         shares available for grant under the Plan at April 30, 2006 was
         4,234,331 options (2005 - 6,481,401; Transition Period - 6,504,794).

         On December 23, 2003 the Company put forth an offer to all eligible
         employees to exchange all of their outstanding, unexercised options to
         purchase common shares of the Company, in exchange for grants of new
         options. All of the 10,373,302 options tendered in the exchange were
         cancelled on January 23, 2004. An equal number of new options were
         granted to the participating employees on July 26, 2004. The new
         options vest in four equal installments commencing one year from the
         date of grant, and have an exercise price of C$1.00 per share, the fair
         value of the Company's common stock on the date of grant.

         Following is a summary of the Company's stock option activity and
         related information. The exercise price of stock options was based on
         prices in Canadian dollars translated at the year-end exchange rate.

         ---------------------------------------------------------------------------------------------------------------------


         Options that are anti-dilutive because the exercise price is greater
         than the average market price of the common shares, are not included in
         the computation of diluted earnings per share. For fiscal 2006,
         20,668,538 stock options were excluded from the above computation of
         diluted EPS because they were anti-dilutive (2004 - 4,277,764; 2005 -
         18,480,002; Transition Period - 18,456,249).

         Stock-based Compensation

         During fiscal 2006, the Company granted stock options to acquire
         132,000 common shares (2004 - nil; 2005 - 145,604; Transition Period -
         nil) stock options at an exercise price equal to the market price of
         the common shares on the date of grant to consultants and advisory
         directors, as well as employees who, subsequent to the options grants,
         became former employees of the Company as a result of restructuring
         activities. The fair market value of these stock options was determined
         using a Black-Scholes model based on the fair value of the common
         shares at the vesting date and, for the unvested shares, as of April
         30, 2005 and April 30, 2006. The following assumptions were used:
         five-year life, interest rate of 3.84 percent, volatility of 100
         percent and no dividends. Unvested stock options granted to
         non-employees must be accounted for based on variable plan accounting.
         Under variable plan accounting, compensation expense is measured as of
         each reporting date as the amount equal to the change in fair value of
         the stock options. Deferred stock compensation of $0.1 was recorded in
         fiscal 2006 and is being amortized over the vesting period of four
         years from the date of grant, with $0.1 (2004 - $0.2; 2005 -
         $insignificant; Transition Period - $nil) amortized into selling,
         general and administrative expense for fiscal 2006. The amount of
         deferred stock compensation expense to be recorded in future periods
         could decrease if options for which accrued but unvested compensation
         has been recorded are forfeited.

         During fiscal 2006, there were no (2004 - 88,000; 2005 - nil;
         Transition Period - nil) stock options granted to employees of the
         Supplier and other companies controlled by the Principal Shareholder.
         The fair market value of the unvested stock options at the grant date
         was determined to be $nil (2004 - $0.1; 2005 - $nil; Transition Period
         - $nil) based on a Black-Scholes model and recognized as a dividend to
         the Principal Shareholder.

         Performance-Based Stock Options

         On July 27, 2005, the shareholders of Mitel approved 2,810,000
         performance-based stock option awards to acquire 2,810,000 common
         shares to selected key employees. These options contingently vest upon
         the achievement of certain targets in accordance with the normal
         four-year vesting term. As the number of common shares that the holders
         will be entitled to is unknown, the options are considered variable
         plan awards as defined by APB 25. Consistent with these requirements,
         the valuation of the performance-based stock options must be remeasured
         for changes in the market price of the underlying stock at the end of
         each reporting period and charged to expense over the four-year vesting
         period. The expense amount recorded for the year ended April 30, 2006
         was $0.1.

                                    30


         Deferred Share Unit Plans

         In December 2004, Mitel granted deferred share units (DSUs) to certain
         executive members of the Company. The number of DSUs that may be
         awarded to each participant is equal to 15% of the participant's annual
         salary less the maximum amount of the participant's eligible retirement
         savings plans contributions in that particular taxable year. Since the
         participant will receive a lump sum payment in cash upon termination of
         employment, the award must be classified as a liability and remeasured
         to reflect changes in the market price of the common shares until
         settlement. For the year ended April 30, 2006 there were 601,547 DSUs
         awarded to executives with a fair value of $0.9 recorded as a liability
         (2005 - 280,912 DSUs and $0.4 recorded as a liability). The
         compensation expense recorded in fiscal 2006 to reflect a change in
         common share fair value was $0.3 (2005 - $nil; Transition Period -
         $nil).

         The income tax (expense) recovery reported differs from the amount

         In assessing the realizability of deferred tax assets, the Company
         considers whether it is more likely than not that some portion or all
         of the deferred tax assets will not be realized. During fiscal 2006,
         the Company determined that certain deferred tax assets relating to its
         U.S. operations are considered more likely than not to be realized and
         therefore reduced its valuation allowance.

         The Company and its subsidiaries had the following tax loss carry
         forwards and tax credits:

         These tax loss carry forwards relate to operations in Canada, the US,
         the U.K., Italy, Hong Kong and Barbados. As a result of the acquisition
         of the Company on February 16, 2001, there are restrictions on the use
         of certain of these losses to offset taxable income in future periods.

         The tax credits relate to the Canadian operations and may be used
         to offset future Canadian federal income taxes payable.

         The Company does not expect the unremitted earnings of its subsidiaries
         will be subject to income tax or withholding taxes as it plans to
         reinvest the earnings of its subsidiaries indefinitely. Accordingly, no
         provision has been made for potential income tax or withholding taxes
         on repatriation of subsidiary earnings.

         The Company is subject to ongoing examinations by certain taxation
         authorities of the jurisdictions in which it operates. The Company
         regularly assesses the status of these examinations and the potential
         for adverse outcomes to determine the adequacy of the provisions for
         income taxes. The Company believes that it has adequately provided for
         tax adjustments that are probable as a result of any ongoing or future
         examination.


25.      PENSION PLANS

         The Company and its subsidiaries maintain defined contribution pension
         plans that cover substantially all employees. In addition, the
         Company's U.K. subsidiary maintains a defined benefit pension plan. The
         Company matches the contributions of participating employees to the
         defined contribution pension plans on the basis of the percentages
         specified in each plan. The costs of the defined contribution pension
         plans are expensed as incurred. The defined benefit plan provides
         pension benefits based on length of service and final average earnings.
         The pension costs of the defined benefit pension plan are actuarially
         determined using the projected benefits method pro-rated on services
         and management's best estimate of the effect of future events. Pension
         plan assets are valued at fair value. The most recent actuarial
         valuation of the plan was performed as of March 31, 2006.

                                    32


         In June 2001, the defined benefit pension plan was closed to new
         employees and a defined contribution option was introduced to members
         of the defined benefit pension plan. Members were given the choice to
         continue in the defined benefit plan or transfer their assets to the
         defined contribution plan.

         In fiscal 2006, a change in valuation assumptions, in particular
         changes in discount rates and increases in expected mortality rates,
         produced an unfavorable impact on the Company's defined benefit pension
         plan assets and obligations. As a result of the change in assumptions,
         the Company increased its minimum pension liability, the amount by
         which the accumulated benefit obligation exceeds the fair value of the
         plan assets, by (pound)9.4 (2005 - (pound)1.3). After the effects of
         foreign currency translation of British Pounds to US dollars, the
         overall pension liability increased by $15.0 to $40.1 (2005 - decrease
         of $0.6 to $25.4, Transition Period - decrease of $0.3 to $25.1). The
         adjustment has been recorded as an increase to the pension liability
         and an increase to accumulated other comprehensive loss on the
         Consolidated Balance Sheet.

         The actuarial present value of the accrued pension benefits and the net
         assets available to provide for these benefits, at market value, were

         The company's Benefit Obligation ("BO") for its significant plans is

         Contributions

         The Company expects contributions of $2.9 to its pension plan in 2007.

         Plan Assets

         The Company's pension plan weighted-average asset allocations at April
         30, 2005 and April 30, 2006 and target allocations for 2007, by asset
         category are as follows:

         The investment objectives of the pension portfolio of assets ("the
         Fund") are designed to generate returns that will enable the Fund to
         meet its future obligations. The performance benchmark for the
         investment managers is to earn in excess of the index return in those
         asset categories, which are actively managed. In setting the overall
         expected rate of return, the various percentages of assets held in each
         asset class together with the investment return expected from that
         class are taken into account. For cash and bonds, the rate used is that
         derived from an appropriate index at the valuation date. For equities,
         a model is used which combines price inflation, dividend yield and an
         allowance for gross domestic product growth.

26.      FINANCIAL INSTRUMENTS

         Fair value

         The Company's financial instruments include cash and cash equivalents,
         restricted cash, bank indebtedness, accounts receivable, other
         receivables, long-term receivables, accounts payable, amounts due to
         (from) related parties, long-term debt including convertible notes,
         derivative instruments, foreign exchange forward contracts and foreign
         exchange swaps. Due to the short-term maturity of cash and cash
         equivalents, restricted cash, accounts receivable, and accounts
         payable, the carrying value of these instruments is a reasonable
         estimate of their fair value. Foreign exchange contracts are carried at
         fair value and amounted to $3.7 classified as accounts payable and
         accrued liabilities at April 30, 2006. At April 24, 2005 and April 30,
         2005, $0.1 and $0.3 was classified as other current asssets
         respectively, and $0.1 and $0.1 classified as accounts payable and
         accrued liabilities, respectively. The fair value of the foreign
         exchange contracts reflects the estimated amount that the Company would
         have been required to pay if forced to settle all outstanding contracts
         at year-end. This fair value represents a point-in-time estimate that
         may not be relevant in predicting the Company's future earnings or cash
         flows. The fair value of long-term receivables and long-term debt was
         determined by discounting future cash receipts and future payments of
         interest and principal, at estimated interest rates that would be
         available to the Company at year-end. The fair value of financial
         instruments approximate their carrying value, with the exception of
         convertible notes. The carrying value of the convertible notes was
         determined based on the allocation of gross proceeds received between
         the notes and the warrants based on their relative estimated fair
         values. The estimated fair value of the convertible notes is $55.1
         (2005 - $55.4). The fair value of derivative instruments is determined
         by management and reflects the present value of the obligation and the
         likelihood of contingent events occurring.

         The following table summarizes the financial assets and liabilities for
         which fair values differed from the carrying amount.

         Credit risk

         The Company's financial assets that are exposed to credit risk consist
         primarily of cash and cash equivalents and accounts receivable and
         other receivables. Cash and cash equivalents are invested in government
         and commercial paper with investment grade credit rating. The Company
         is exposed to normal credit risk from customers. However, the Company's
         orientation is global with a large number of diverse customers to
         minimize concentrations of credit risk.

         Interest rate risk

         The Company is exposed to interest rate risk on its credit facilities
         which bear interest rates based on the prime rate, and is also exposed
         to risk on its convertible notes which bear interest based on the
         London Inter-Bank Offer Rate or "LIBOR". In September 2005, the Company
         entered into a derivative contract to limit the impact of changes in
         LIBOR on interest expense related to the convertible notes for the
         period commencing November 1, 2005 and ending November 1, 2007. This
         derivative contract effectively provides a cap on LIBOR of 5.27% and a
         floor on LIBOR of 4.00%. The Company is not exposed to other
         significant interest rate risk due to the short-term maturity of its
         monetary assets and current liabilities

         Foreign currency risk

         The Company is exposed to currency rate fluctuations related primarily
         to its future net cash flows from operations in US dollars, British
         pounds and Euros. The Company uses foreign currency forward contracts
         and foreign currency swaps to minimize the short-term impact of
         currency fluctuations on foreign currency receivables, payables and
         intercompany balances. These contracts are not entered into for
         speculative purposes, and are not treated as hedges for accounting
         purposes. Foreign currency contracts are recorded at fair market value.
         Related foreign currency gains and losses are recorded in other
         expense, net, in the consolidated statements of operations and offset
         foreign exchange gains or losses from the revaluation of intercompany
         balances and other current assets and liabilities denominated in
         currencies other than the functional currency of the reporting entity.

         The foreign exchange contracts outstanding at April 30, 2006 are due to
         mature in May 2006. As of April 30, 2006, other income (expense), net
         included a net unrealized loss of $3.7 (2004 - gain of $0.2; 2005 -
         insignificant gain; Transition Period - $0.2) for changes in the fair
         value of foreign exchange contracts. As at April 30, 2006, the Company
         had outstanding foreign exchange contracts requiring it (i) to exchange
         British Pounds for Canadian dollars with aggregate notional amounts of
         C$13.2 (2005 - C$nil), (ii) to exchange US dollars for Canadian dollars
         with a notional amount of C$83.9 (2005 - C$17.2), and (iii) to exchange
         Euro dollars for Canadian dollars with aggregate notional amounts of
         C$11.4 (2005 - C$10.3).

                                    35


         Non-derivative and off-balance sheet instruments

         Requests for providing commitments to extend credit and financial
         guarantees are reviewed and approved by senior management. Management
         regularly reviews all outstanding commitments, letters of credit and
         financial guarantees, and the results of these reviews are considered
         in assessing the adequacy of the Company's reserve for possible credit
         and guarantee losses. As of April 24, 2005, April 30, 2005 and April
         30, 2006, there were no outstanding commitments to extend credit to
         third parties or financial guarantees outstanding other than letters of
         credit. Letters of credit amounted to $1.2 as of April 30, 2006 (April
         30, 2005 - $1.6). The estimated fair value of letters of credit, which
         is equal to the fees paid to obtain the obligations, was insignificant
         as of April 24, 2005, April 30, 2005 and April 30, 2006.

28.      RECONCILIATION FROM US GAAP TO CANADIAN GAAP

         New Canadian regulations allow issuers that are required to file
         reports with the SEC, upon meeting certain conditions, to satisfy their
         Canadian disclosure obligations by using financial statements prepared
         in accordance with US GAAP. Accordingly, effective Fiscal 2005, Mitel
         will include in the notes to its consolidated financial statements a
         reconciliation highlighting the material differences between its
         financial statements prepared in accordance with US GAAP as compared to
         financial statements prepared in accordance with accounting principles
         generally accepted in Canada ("Canadian GAAP"). Prior to Fiscal 2005,
         Mitel prepared financial statements (with accompanying notes) in
         accordance with Canadian GAAP, which were presented as a separate
         report and provided to its Canadian shareholders. Subsequent to 2006,
         no further reconciliation or financial statement presentation in
         accordance with Canadian GAAP will be required under current Canadian
         regulations. Mitel will therefore not present Canadian GAAP financial
         statements or a reconciliation from US GAAP to Canadian GAAP in 2007.

         The consolidated financial statements of Mitel have been prepared in
         accordance with US GAAP and the accounting rules and regulations of
         the SEC which differ in certain material respects from those
         principles and practices that Mitel would have followed had its
         consolidated financial statements been prepared in accordance with
         Canadian GAAP. The following is a reconciliation of the

                                     37



         The significant differences between US GAAP and Canadian GAAP that
         impact the consolidated financial statements of Mitel include the
         following:

         a) Accounting for redeemable shares

         Under US GAAP, as described further in Notes 19 and 20, redeemable
         shares are presented in the mezzanine section of the Consolidated
         Balance Sheets, and are accreted to their redemption values over the
         period to redemption. The accreted amounts are recorded as a deemed
         dividend in the Consolidated Statements of Shareholders' Deficiency.
         Furthermore, as a portion of the redemption price of the redeemable
         preferred shares is indexed to the common share price of the Company,
         an embedded derivative exists which is accounted for at fair value
         separate from the host contract, as required under the provisions of
         FASB Statement No. 133, Accounting for Derivative Instruments and
         Hedging Activities. The embedded derivative is marked to market
         throughout the period to redemption with changes in value recorded in
         the Consolidated Statements of Operations.

         Under current Canadian GAAP, embedded derivatives are not accounted for
         separately from the host contract. The carrying value of the redeemable
         shares is recorded as a liability, and accreted to redemption value
         over the period to redemption. The accreted amounts are recorded as
         non-cash interest expense in the Consolidated Statements of Operations.
         Furthermore, a conversion option exists under Canadian GAAP for the
         convertible, redeemable preferred shares, which was valued using the
         residual approach and is recorded as Contributed Surplus.

         b) Pension and other post retirement benefits

         Under US GAAP, a minimum pension liability adjustment must be
         recognized in the amount of the excess of the unfunded accumulated
         benefit obligation over the recorded pension benefit liability. An
         offsetting intangible pension asset is recorded equal to the
         unrecognized prior service costs, with any difference recorded in
         accumulated other comprehensive loss. No such adjustments are required
         under Canadian GAAP.

         c) Stock based compensation

         Under US GAAP, FASB Statement No. 123, Accounting for Stock-Based
         Compensation, ("SFAS 123") permits companies the choice between
         recording compensation expense for the fair value of stock based awards
         to employees, and disclosing such expense in the notes to the financial
         statements. Mitel has elected to adopt the disclosure provisions of
         SFAS 123, and only records employee stock based compensation expense
         when the exercise price is lower than the market price on the date of
         grant (see note 3(q)). Non-employee stock based compensation is
         recorded as an expense as required under SFAS 123.

         Under Canadian GAAP, CICA Handbook Section 3870, Stock-based
         Compensation and Other Stock-based Payments ("Section 3870"),
         establishes standards for the recognition, measurement and disclosure
         of stock-based compensation and other stock-based payments. Section
         3870 outlines a fair value based method of accounting required for
         certain stock-based transactions, effective January 1, 2002, and
         applied to awards granted on or after that date. Prior to Fiscal 2005,
         as permitted by Section 3870, Mitel did not adopt the provisions in
         respect of the fair value based method of accounting for its employee
         stock-based transactions. Effective Fiscal 2005, Mitel adopted the full
         provisions of Section 3870, and recognizes an expense for employee
         stock-based compensation using the fair value based method
         prospectively for all awards granted, modified, or settled on or after
         January 1, 2003, in accordance with the transitional provisions of
         Section 3870. Non employee stock based compensation is recorded as an
         expense under both Canadian and US GAAP, however the expense under
         Canadian GAAP is effective for non-employee options granted after the
         date on which the Canadian GAAP rules came into effect on January 1,
         2002.

         d) Convertible debentures

         On August 16, 2002, Mitel closed a private offering of debentures
         convertible into shares of the Company that resulted in total cash
         proceeds of $6.5. The debentures provided for interest to accrue at the
         rate of 6.5% per annum payable on the maturity date or upon conversion
         of the debentures and accrued interest into common shares of the
         Company. The principal amount of the debentures, together with accrued
         interest outstanding under the debentures was subject to mandatory
         conversion, and would automatically convert into shares in the Company
         upon the occurrence of certain events. Under US GAAP, the debentures
         were recorded as a liability, and interest expense was recorded in the
         Consolidated Statements of Operations. Under Canadian GAAP the
         debentures were deemed to be equity instruments and classified in the
         Shareholders' Deficiency section of the Consolidated Balance Sheets.
         Accordingly, interest expense was not recorded in the Consolidated
         Statements of Operations under Canadian GAAP, but was recorded as a
         deemed dividend.

         The full amount of the debentures was converted into common shares of
         the Company during Fiscal 2004, and subsequently exchanged for
         convertible, redeemable preferred shares (see Note 20). This resulted
         in a beneficial conversion feature under US GAAP, however no such
         requirement existed under Canadian GAAP.

         e) Foreign exchange loss on long term investment

         During Fiscal 2005, Mitel Networks Inc. ("MNI"), a wholly owned
         subsidiary of Mitel Networks Limited ("MNL"), agreed to redeem
         82.6 common shares in exchange for a payment of $28.0 to Mitel
         Networks Limited ("MNL"), a wholly owned subsidiary of the
         Company. The 82.6 common shares were subsequently cancelled. The
         transaction did not involve any external third parties, and MNL
         continued to own 100% of MNI prior to and subsequent to the
         transaction. Under Canadian GAAP, a portion of the


                                     38


         cumulative translation adjustments relating to MNL's ownership
         interest in MNI was included in the determination of net loss,
         resulting in a foreign exchange loss of $8.7. No such requirement
         exists under US GAAP.

         f) Other financial statement presentation differences

         Under U.S. GAAP, translation adjustments for self-sustaining
         subsidiaries are reported as a component of other comprehensive
         income (loss), whereas, under Canadian GAAP, these translation
         adjustments are classified as foreign currency translation
         adjustment, also a component of shareholders' deficiency.


29.      SUBSEQUENT EVENTS

         On May 9, 2006, the Company filed a registration statement on Form F-1
         under the Securities Act of 1933 to sell common shares in the United
         States and a preliminary prospectus with the Canadian securities
         regulators to sell common shares in Canada. After completion of the
         initial public offering, all outstanding Series A and Series B
         Preferred Shares will automatically convert into common shares;
         warrants held by a financing agent and warrants issued in connection
         with the Series A Preferred Shares will be exercised; and the
         redemption right attached to the Redeemable Common Shares will
         terminate. The derivative liability balance recorded in connection with
         the issuance of Series A and Series B Preferred Shares will also be
         reclassified to equity as a result of the offering and the subsequent
         Preferred Shares conversion. The impact of these conversions is
         summarized and presented in the pro forma balance sheet information.

         On June 23, 2006, one of the Company's competitors filed a complaint in
         the United States District Court for the Eastern District of Virginia
         alleging that the Company is infringing on certain of its patents and
         requesting damages (treble damages in respect of alleged willful
         infringement of the patents), injunctive relief, attorney's fees, costs
         and expenses, and such further relief against us as the court deems
         just and proper. The plaintiff also filed a complaint in the United
         States District Court for the District of New Jersey seeking a
         declaratory judgment that certain of the Company's patents are not
         being infringed by the plaintiff or are invalid. The Company has not
         yet been served with a copy of either complaint. The plaintiff has not
         asserted any particular amount of damages in its complaint.
         Consequently, the Company is not able to determine the amount of
         damages that might be awarded in the event the Company is found liable
         for infringement of the plaintiff's patents or that the Company would
         be to continue to use the technology that the plaintiff alleges
         infringes the patents at suit. The Company intends to vigorously defend
         itself against these complaints.

         On June 26, 2006 an amendment to the shareholders' agreement was
         executed by the parties to the agreement which defers the put date in
         connection with 10,000,000 common shares (see note 19) and 16,000,000
         Series B Preferred Shares (see note 20) from September 1, 2006 to May
         1, 2007.

To the Shareholders of Mitel Networks Corporation

You are invited to attend the Annual and Special Meeting of Shareholders of
Mitel Networks Corporation to be held at The Brookstreet Hotel, 525 Legget
Drive, Ottawa, Ontario, Canada on Thursday, September 7, 2006 at 2:30 p.m.,
(Ottawa time).

On May 9th, 2006, Mitel filed a preliminary prospectus for an initial public
offering and secondary offering of its common shares in Canada and in the
United States. In addition to presenting customary annual business at the
Meeting, Mitel proposes to amend the articles and the by-laws of Mitel and to
adopt a new equity incentive plan, all as described in the attached management
proxy circular. At the Meeting, in addition to approving customary annual
business, shareholders will also be asked to:

     o    Approve a change of the permitted range of number of directors to a
          minimum of three (3) and a maximum of fifteen (15) and permit the
          directors to determine the number of directors within such range;

     o    Approve the change of name of the Corporation from Mitel Networks
          Corporation to Mitel Corporation;

     o    Authorize and approve the Corporation's 2006 Equity Incentive Plan;
          and

     o    Confirm amendments to By-law No. 1A.

The holders of the common shares, the class A shares and the class B shares
will vote together as a single class on all matters to be approved by
shareholders. The enclosed management proxy circular provides a further
description of the proposed business of the Meeting to assist you in
considering the matters to be voted upon. You are urged to review this
information carefully.

Your vote is important. Shareholders who are unable to attend the Meeting in
person are encouraged to read the enclosed management proxy circular and then
complete, date, sign and return a form of proxy unless your shares are
registered in the name of an intermediary, in which case you should complete
the form of proxy delivered to you by the intermediary. Non-registered
shareholders should carefully follow the instructions of their intermediaries.

Thank you for your continued support of Mitel. We look forward to seeing you at
the Meeting.


Sincerely,


/s/ Donald W. Smith

                           MANAGEMENT PROXY CIRCULAR

A.   INFORMATION ON VOTING AND PROXIES

1.   Solicitation of Proxies

This management proxy circular (the "Management Proxy Circular" or the
"Circular") is furnished in connection with the solicitation of proxies by or on
behalf of the management of Mitel Networks Corporation ("Mitel" or the
"Corporation"), a corporation governed by the Canada Business Corporations Act
(the "CBCA"), for use at the annual and special meeting, or any adjournment or
adjournments thereof (the "Meeting"), of the shareholders of the Corporation
(each, a "Shareholder") to be held on Thursday, September 7th, 2006 at The
Brookstreet Hotel, 525 Legget Drive, Ottawa (Kanata), Ontario, Canada, K2K 2W2,
commencing at 2:30 p.m., Ottawa time, for the purposes set out in the notice of
the Meeting (the "Notice of Meeting") accompanying this Management Proxy
Circular.

The enclosed proxy is being solicited by or on behalf of the management of the
Corporation and the cost of such solicitation will be borne by the Corporation.
It is expected that the solicitation of proxies will be primarily by mail,
telephone or electronic communication by directors, officers or employees of
Mitel. Proxies may also be solicited personally or by telephone or electronic
communication by officers and employees of Mitel. Except as otherwise stated,
the information contained in this Management Proxy Circular is given as of July
31st, 2006.

Unless otherwise provided herein, all dollar amounts in this Management Proxy
Circular are stated in Canadian dollars.

2.   Appointment of Proxies

The persons named in the enclosed form of proxy are directors or officers of the
Corporation. If you wish to appoint some other person or company (who need not
be a Shareholder) to represent you at the Meeting, you may do so by striking out
the name of the persons named in the enclosed form of proxy and inserting the
name of your appointee in the blank space provided or complete another form of
proxy and, in either case, deliver the completed and signed proxy in the
envelope provided to Mitel Networks Corporation, Attention: Corporate
Secretary's Office, 350 Legget Drive, Ottawa, Ontario K2K 2W7 or by facsimile at
(613) 592-7813 by 12:00 p.m. (noon), Ottawa time, on Wednesday, September 6th,
2006, being the business day preceding the date of the Meeting. It is the
responsibility of the Shareholder appointing some other person to represent it
to inform such person that he or she has been so appointed. The proxy must be
signed by the Shareholder or the Shareholder's attorney authorized in writing
or, if the Shareholder is a corporation, by an officer or attorney thereof, duly
authorized.

Registered Shareholders

A registered shareholder is the person in whose name a share certificate is
registered. If you are a registered shareholder, you are entitled to vote your
shares in person at the Meeting or by proxy. If you wish to vote in person at
the Meeting, do not complete or return the form of proxy included with this
Circular. Your vote will be taken and



                                    - 2 -




counted at the Meeting. If you do not wish to attend the Meeting or do not
wish to vote in person, you may vote by proxy by delivering the completed and
signed form of proxy in the envelope provided to Mitel Networks Corporation,
Attention: Corporate Secretary's Office, 350 Legget Drive, Ottawa, Ontario K2K
2W7 or by facsimile at (613) 592-7813 by 12:00 p.m. (noon), Ottawa time, on
Wednesday, September 6th, 2006, being the business day preceding the date of
the Meeting. In each case, the shares represented by your proxy will be voted
in accordance with your instructions as indicated on your form of proxy and on
any ballot that may be called at the Meeting. Your proxyholder will decide how
to vote on amendments or variations to the matters to be voted on at the
Meeting. Instructions for using each of these methods are set out on the
enclosed form of proxy.

Non-Registered Shareholders

Your shares may not be registered in your name but in the name of an
intermediary (which is usually a bank, trust company, securities dealer or
broker, or trustees or administrators of self-administered RRSPs, RRIFs, RESPs
and similar plans). If your shares are registered in the name of an
intermediary, you are a non-registered shareholder.

Mitel has distributed copies of the Notice of Meeting, this Circular and the
form of proxy (collectively, the "Meeting Materials") to intermediaries for
distribution to non-registered shareholders. Unless you have waived your right
to receive the Meeting Materials, intermediaries are required to deliver them to
you as a non-registered shareholder of the Corporation and to seek your
instructions regarding how to vote your shares.

Non-registered shareholders who receive Meeting Materials from the intermediary
will typically be given the ability to provide voting instructions in one of two
ways. Usually, a non-registered shareholder will be given a voting instruction
form which must be completed and signed by the non-registered shareholder in
accordance with the instruction on the form (which may, in some cases, permit
the completion of the voting instruction form by telephone or electronically).

Occasionally, an intermediary may give you a proxy that has already been signed
by the intermediary (typically by a facsimile, stamped signature), and which is
otherwise uncompleted. This form of proxy does not need to be signed by you as
the non-registered shareholder. In this case you can complete and deposit the
proxy directly as described above.

By following these procedures, a non-registered shareholder will be able to
direct the voting of those shares that they own but which are not registered in
their own name. Should a non-registered shareholder who receives from the
intermediary either a proxy or a voting instruction form wish to attend and vote
at the Meeting in person (or have another person attend and vote on their
behalf), the non-registered shareholder should strike out the names of the
persons named in the form of proxy and insert the non-registered shareholder's
(or such other person's) name in the blank space provided or, in the case of a
voting instruction form, follow the corresponding directions on the form. In
either case, non-registered shareholders should carefully follow the
instructions of their intermediaries.

Proxies returned by intermediaries as "non-votes" because the intermediary has
not received instructions from the non-registered shareholder with respect to
the voting of certain shares will be treated as not entitled to vote on any such
matter and will not be counted as having been voted in respect of any such
matter. Shares represented by intermediary "non-votes" will, however, be counted
in determining whether there is a quorum.

3.   Revocation of Proxies

In addition to revocation in any other manner permitted by law, a Shareholder
may revoke a proxy under subsection 148(4) of the CBCA by depositing an
instrument in writing executed by the Shareholder or by the Shareholder's
attorney authorized in writing (or, if the Shareholder is a corporation, by an
authorized officer or attorney thereof authorized in writing) at the registered
office of the Corporation at any time up to and including the last business day
preceding the day of the Meeting at which such proxy is to be used, or with the
Chairman of the Meeting on the day of, but prior to commencement of, the
Meeting, or in any other manner permitted by law, and upon either of such
deposits such proxy shall be revoked. If the instrument of revocation is
deposited with the Chairman of the Meeting on the day of the Meeting, the
instrument will not be effective with respect to any matter on which a vote has
already been cast pursuant to such proxy.




                                    - 3 -




4.   Voting of Proxies

The form of proxy affords the Shareholder an opportunity to specify that the
shares registered in the Shareholder's name shall be voted FOR or AGAINST or
WITHHELD in accordance with your instructions as indicated on your form of
proxy. In the absence of instructions, your shares will be voted FOR each of the
matters to be considered at the Meeting. Votes WITHHELD and abstentions are
counted as present or represented for purposes of determining the presence or
absence of a quorum, but are not included in the number of shares present or
represented and voting on each matter.

The form of proxy accompanying this Management Proxy Circular confers
discretionary authority upon the nominees named in the enclosed form of proxy
with respect to amendments or variations of matters identified in the Notice of
Meeting or other matters which may properly come before the Meeting. As of the
date of this Management Proxy Circular, management of Mitel knows of no
amendment or variation of the matters referred to in the Notice of Meeting or
other business that will be presented at the Meeting. If any such matters should
properly come before the Meeting, each nominee named in the enclosed form of
proxy will vote on those matters in accordance with his or her best judgment.

5.   Authorized Capital and Voting Shares

The authorized capital of the Corporation consists of:

a)   an unlimited number of Common Shares ("Common Shares");

b)   an unlimited number of Class A Convertible Preferred Shares, issuable in
     series, of which one series, consisting of an unlimited number of Class A
     Convertible Preferred Shares, Series 1 (the "Series A Shares"), has been
     designated; and

c)   an unlimited number of Class B Convertible Preferred Shares, issuable in
     series, of which one series, consisting of an unlimited number of Class B
     Convertible Preferred Shares, Series 1 (the "Series B Shares"), has been
     designated.

As of July 31st, 2006, the Corporation had 117,340,263 Common Shares, 20,000,000
Series A Shares and 67,789,300 Series B Shares issued and outstanding
(collectively, the Shares"). Each Common Share currently carries one vote in
respect of each matter to be voted upon at the Meeting. Each Series A Share and
each Series B Share currently carries a number of votes calculated based on a
formula set out in the share provisions of each series. For the purposes of this
Meeting, the Corporation has determined that each Series A Share and each Series
B Share shall have one vote per share.

The holders of the Common Shares, the Series A Shares and the Series B Shares
will vote together as a single class on all resolutions considered at the
Meeting.

Only holders of outstanding Shares of record at the close of business on the day
immediately preceding the day on which the Notice of Meeting is mailed will be
entitled to vote at the Meeting, except to the extent that a person has
transferred Shares after that date and the transferee of such Shares establishes
proper ownership and has demanded not later than 10 days before the Meeting that
his/her/its name be included in the list to vote at the Meeting, in which case
the transferee is entitled to vote such Shares at the Meeting.

6.   Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information with respect to all persons known by
the Corporation to be the beneficial owner, directly or indirectly, of or who
exercise control or direction over shares carrying more than 10% of the votes
attached to any class of shares entitled to vote at the Meeting:

----------------------------------------------------------------------------------------------------------------------



(1) Calculated on an as-if-converted to Common Shares basis if the Series A
Shares and the Series B Shares were to be converted into Common Shares on a
one-for-one basis. The Series A Shares and the Series B Shares are convertible
into Common Shares based on a formula that depends on the fair market value of
the Common Shares. Accordingly, if and when the Series A Shares and Series B
Shares are converted, they will be converted into Common Shares on a greater
than one-for-one basis.

(2) Dr. Terence H. Matthews, Chairman of the Corporation, controls, directly or
indirectly, Wesley Clover Corporation and CTJL.

B.   ANNUAL BUSINESS TO BE TRANSACTED AT THE MEETING

1.   Financial Statements

The consolidated financial statements of the Corporation for the fiscal year
ended April 30th, 2006 and the auditors' report thereon will be presented to the
Meeting. The audited consolidated financial statements accompany this Circular
and, in accordance with the provisions of the CBCA, the financial statements
will not be the subject of any vote at the Meeting.

2.   Annual Resolution No. 1 - Fixing the Number of Directors and Election of
     Directors

The articles of the Corporation provide for a board of directors (the "Board")
of not less than one director and not more than 10 directors to be elected
annually, with the fixed number of directors within such range from time to time
authorized by the shareholders of the Corporation. At a special meeting held on
April 20th, 2004, the shareholders of the Corporation fixed the number of
directors at eight and there are currently seven directors. Sir David
Rowe-Beddoe resigned as a director on May 8th, 2006. Management proposes to fix
the number of directors at seven and to nominate seven persons to be elected to
the Board at the Meeting. Each director who is elected will hold office until
the next annual meeting of shareholders, or until a successor is duly elected or
appointed, unless the office is earlier vacated in accordance with the by-laws
of the Corporation, the CBCA or the Shareholders Agreement (as defined and
discussed under the heading "Interest of Management, Nominees and Others in
Material Transactions" in Part E of this Circular).

The seven current directors were elected at the last annual meeting of
shareholders.

Pursuant to the Shareholders Agreement, EdgeStone is entitled to nominate two
directors to the Board. Gilbert S. Palter and Guthrie J. Stewart are the
nominees of Edgestone. The parties to the Shareholders Agreement agreed, among
other matters, to act and vote from time to time so that on any election of
directors by the Shareholders of the Corporation, that the Edgestone nominees
are elected.

A majority of the votes cast, in person or by proxy, is required for approval of
fixing the number of directors at seven and the election of directors. The
persons named in the form of proxy will, unless a proxy specifies that the
shares it represents shall be voted AGAINST in respect of the fixing of the
number of directors


                                    - 5 -



or WITHHELD from voting in respect of the election of directors or unless
someone else is appointed as proxy holder, be voted FOR the fixing of the
number of directors at seven and FOR the election of the nominees for director
listed below. In the event a nominee is unable or unwilling to serve, (an
event that management has no reason to believe will occur), the persons named
in the form of proxy will vote for a substitute nominee in accordance with his
or her best judgment.

The following table sets forth the name of each person nominated for election as
a director; the period or periods of service as a director; the principal
occupation, business or employment, and all positions with the Corporation and
any significant affiliate of the Corporation, within the preceding five years,
as well as the number of shares beneficially owned or over which control or
direction is exercised. All of the listed nominees currently serve as directors
of the Corporation.

3.   Annual Resolution No. 2 - Appointment and Remuneration of Auditors

Appointment of Auditors

On the recommendation of the Audit Committee, management proposes to present a
resolution ("Annual Resolution No. 2") to appoint Deloitte & Touche LLP,
Chartered Accountants, Ottawa, Ontario, as auditors of the Corporation for the
fiscal year ending April 2007 to hold office until the close of the next annual
meeting of shareholders. Deloitte & Touche LLP were first appointed auditors of
the Corporation on December 4th, 2001.

Remuneration of Auditors

In the past, the Audit Committee has negotiated with the auditors of the
Corporation on an arm's length basis for the purpose of determining the fees to
be paid to the auditors. Such fees have been based upon the complexity of the
matters in question and the time incurred by the auditors. Management believes
that the fees negotiated in the past with the auditors of the Corporation were
reasonable in the circumstances and would be comparable to fees charged by other
auditors providing similar services.

The persons named in the form of proxy will, unless a Shareholder has instructed
that the shares it represents be WITHHELD from voting in respect of the
appointment of auditors or someone else is appointed as proxy holder, be voted
FOR the appointment of Deloitte & Touche LLP as auditors of the Corporation and
to authorize the directors to fix the remuneration of the auditors.

C.   DIRECTOR AND EXECUTIVE COMPENSATION

1.   Executive Compensation

Cash and Other Remuneration of Executive Officers

During the fiscal year ended April 30th, 2006, there were eight executive
officers of the Corporation (the "Executive Officers"), as that term is defined
in the CBCA. The aggregate cash remuneration paid to the Executive Officers by
the Corporation and its subsidiaries for services rendered during the fiscal
year ended April 30th, 2006, was $3,181,426. Except as noted in this Circular,
no other form of compensation has been provided to the Executive Officers. Other
than the Corporation's stock option plan and deferred stock unit plan summarized
below, the Corporation does not have any plan pursuant to which cash or non-cash
remuneration was paid or distributed to Executive Officers during the fiscal
year ended April 30th, 2006, or is proposed to be so paid or distributed in a
subsequent year.



                                    - 7 -

Stock Option Plan


The Corporation adopted an employee stock option plan (the "Stock Option Plan")
in March 2001. Further amendments to the Stock Option Plan have been approved by
the Board from time to time in accordance with section 24 of the Stock Option
Plan. The Stock Option Plan provides for the grant of options to acquire Common
Shares to employees, directors and consultants of the Corporation.

The Stock Option Plan provides that a committee of the Board (the "Compensation
Committee") has the authority to determine the individuals to whom options will
be granted, the number of Common Shares subject to option grants and other terms
and conditions of option grants. The Stock Option Plan also provides that,
unless otherwise determined by the Compensation Committee, one-quarter of the
Common Shares that an option holder is entitled to purchase become eligible for
purchase on each of the first, second, third and fourth anniversaries of the
date of grant, and that options expire on the fifth anniversary of the date of
grant. The Stock Option Plan provides that in no event may an option remain
exercisable beyond the tenth anniversary of the date of grant.

As at July 31st, 2006, there are 25,000,000 Common Shares representing
approximately 12% of the outstanding Shares (calculated on an as-if-converted to
Common Share basis) reserved for issuance upon the exercise of options granted
under the Stock Option Plan of which options to acquire 19,587,508 Common Shares
are currently issued and outstanding under the Stock Option Plan.

A component of executive remuneration consists of grants of stock options under
the Stock Option Plan. Options are also granted under the Stock Option Plan to
attract new executives, retain employees and recognize job promotions.

During the fiscal year ended April 30th, 2006, the Board granted options to six
Executive Officers to purchase a total of 1,225,000 Common Shares at a price of
$1.00 per Common Share. The exercise of certain of these options is subject to
meeting specific performance goals. As at April 30th, 2006, options to acquire
500,000 Common Shares were subject to meeting specific performance goals.
Following the end of the fiscal year, options to acquire 350,000 of these Common
Shares were cancelled as a result of termination of employment and failure to
meet specific performance goals. There were no options exercised by the
Executive Officers during the fiscal year ended April 30th, 2006.

Deferred Share Unit Plan for Executives

The Corporation adopted a deferred share unit plan for executives (the "DSU
Plan") on December 9th, 2004 in order to promote a greater alignment of
interests between the executives and shareholders. Under the DSU Plan, the
Compensation Committee may award certain executives of the Corporation (a "DSU
Plan Participant") deferred share units ("DSUs") of the Corporation. DSUs are
not considered shares of the Corporation, nor is the holder of any DSU entitled
to voting rights or any other rights attaching to the ownership of shares.

Upon the determination by the Compensation Committee to award DSUs to the
account of a DSU Plan Participant for a particular calendar year, the number of
DSU's to be awarded shall be determined by the Compensation Committee as
follows: (1) as at December 31 of such year the Compensation Committee shall
determine the Supplementary Benefits Amount, which is an amount equal to 15% of
the DSU Plan Participant's annual salary for such year, less the maximum amount
of eligible registered retirement savings plan contributions for the DSU Plan
Participant; and (2) the Supplementary Benefits Amount for such DSU Plan
Participant shall subsequently be divided by the Award Market Value of a DSU.

The Award Market Value of a DSU is equal to: (1) the value of a Common Share of
the Corporation as determined by the Compensation Committee in good faith and in
accordance with and subject to the terms of the DSU Plan; or (2) where the
Common Shares of the Corporation are publicly traded on the Toronto Stock
Exchange ("TSX"), the weighted average trading price of the Common Shares of the
Corporation on the TSX on the five (5) trading days immediately preceding the
date a DSU is awarded.

Upon the DSU Plan Participant ceasing to be an executive of the Corporation, the
DSU Plan Participant shall receive a cash amount equal to the number of DSUs in
his or her account multiplied by the weighted average trading price of the
Common Shares of the Corporation on the TSX on the five (5) trading days
immediately preceding the date


                                    - 8 -



the DSU Plan Participant ceases to be an executive of the Corporation, or on a
later date selected by the DSU Plan Participant, which shall in any event be a
date prior to the end of the following calendar year.

There are currently two DSU Plan Participants. Paul Butcher, President & Chief
Operating Officer is the only DSU Plan Participant who is also an Executive
Officer. As at July 31st, 2006, 340,612 DSUs have been awarded to Mr. Butcher
under the DSU Plan. Of the DSUs awarded to Mr. Butcher, 242,062 DSUs represents
the value of Mr. Butcher's interest in the Corporation's supplementary executive
retirement plan (being $242,062) which was transferred by the Corporation (with
the consent of Mr. Butcher) to the DSU Plan on July 9th, 2005: the supplementary
executive retirement plan has since been wound-up and terminated by the
Corporation (with the consent of the participants thereunder), in favour of the
DSU Plan.

Loans to Directors and Executive Officers

There are no loans outstanding from the Corporation to any of its directors or
the Executive Officers.

2.   Remuneration of Directors

A director who is not also an Executive Officer is reimbursed for any
out-of-pocket expenses incurred in connection with attending Board or committee
meetings. In addition, directors of the Corporation are eligible to participate
in the Stock Option Plan described above.

Non-executive directors are compensated with either cash or stock options in
lieu of cash. The number of stock options granted is calculated using the cash
value divided by the Black-Scholes value at the time of grant.

The cash remuneration for non-executive directors is based on the following:

  Annual Service on the Board (other than Chair)                        $25,000
  Annual Service as Chair of the Board                                  $60,000
  Annual Service as member of the Audit Committee (other than Chair)    $ 5,000
  Annual Service as Chair of the Audit Committee                        $15,000
  Annual Service as member of other standing committees                 $ 2,500
  Annual Service as Chair of other standing committees                  $ 7,500
  Meeting fees                                                          $ 1,000

Each of the non-executive directors opted to receive their compensation in the
form of stock options in lieu of cash.

During the fiscal year ended April 30th, 2006, the Corporation remunerated
non-executive directors of the Corporation with stock options to acquire an
aggregate of 337,026 Common Shares granted under the Stock Option Plan at an
exercise price of $1.00 per Common Share. There were no options exercised by
directors during the fiscal year ended April 30th, 2006.

D.   CORPORATE GOVERNANCE PRACTICES

The Corporation and its management place significant emphasis on the structure
of the Board and the committees of the Board in order to promote effective
corporate governance of the Corporation. During fiscal year 2006, the
Corporation implemented several corporate governance initiatives in order to
conform to the fullest extent possible with current recommended corporate
governance guidelines and best practices.

The initiatives implemented during the fiscal year 2006 included the adoption of
corporate governance guidelines, the adoption of a mandate for the board of
directors and position descriptions for a chairman of the board, a lead director
and a chief executive officer. In addition, the Board adopted a revised audit
committee charter and compensation committee charter and adopted a charter for a
nominating and corporate governance committee.

The Corporation has also adopted a Code of Business Conduct which was revised
during fiscal year 2006. Employees are required to certify their compliance with
the Code on an annual basis. The Corporation has also


                                    - 9 -


adopted a whistleblower policy and, in fiscal year 2003, the Corporation
established a disclosure committee. Certain employees who are involved in the
preparation and review of financial statements and regulatory filings execute,
on an annual basis, certifications in support of the certification obligations
of the chief executive officer and the chief financial officer pursuant to the
Sarbanes Oxley Act of 2002. The certification process complements the due
diligence process administered by the Corporation to support reporting
obligations under the Sarbanes Oxley Act of 2002. The Corporation has also
adopted but has not yet implemented an insider trading policy which will
govern the conduct of directors, officers, employees and certain other persons
in purchasing or selling securities of the Corporation. The Corporation has
also adopted a communications policy which will govern the public
communication and disclosure of corporate information to the public.

1.   Composition of the Board

As discussed under the heading "Special Resolution No. 1 - Change Number of
Directors", Shareholders are being asked to consider and if thought fit, approve
an amendment to the articles to authorize the directors to determine, between
meetings of shareholders, the fixed number of directors to be appointed within
the minimum and maximum number permitted. In addition, Shareholders are being
asked to consider and, if thought fit, approve an increase in the minimum number
of directors from one (1) to three (3) and an increase in the maximum number of
directors from ten (10) to fifteen (15).

Following the Meeting, subject to Shareholder approval, the Board will be
comprised of seven directors. The Board will regularly assess the need for
additional directors in order to ensure that the Board is composed of
individuals with diverse backgrounds, experience, competencies and independence
as evaluated against criteria established from time to time by the Board.

2.   Mandate of the Board and Corporate Governance Guidelines

The statutory mandate of the Board is to supervise the management of the
Corporation. The Board's primary roles are to oversee corporate performance and
provide quality, depth and continuity of management to meet the Corporation's
strategic objectives. The Board focuses its attention on the following key

     o   Maintain shareholder relations

     o   Develop and oversee the Corporation's approach to governance

The corporate governance guidelines describe the governing roles of and the
relationships between the Board and Management. In addition, the guidelines set
forth operating and procedural guidelines for the Board.

The Board has established two committees to assist it in carrying out its
responsibilities: the Audit Committee and the Compensation Committee. The Board
has also adopted a charter for a nominating and corporate governance committee,
but such committee has not yet been constituted.

F.   DIRECTORS' AND OFFICERS' INSURANCE AND INDEMNIFICATION

The Corporation maintains directors' and officers' liability insurance in the
amount of US$15,000,000 for the benefit of directors and officers of the
Corporation. The Corporation's premium is US$145,500, which covers a
twelve-month period from November 1st, 2005 to October 31st, 2006. No portion of
the premium was paid by the directors and officers of the Corporation. The
policy contains deductibles (US$75,000 for employment practices claims and
US$50,000 for all other claims, including securities claims) applicable to
losses for which reimbursement is sought and contains a number of exclusions and
limitations to the coverage provided, as a result of which the Corporation may,
under certain circumstances, be obligated to indemnify its directors or officers
for certain claims which do not fall within the coverage provided under the
policy.

The by-laws of the Corporation generally provide that the Corporation shall
indemnify a director or officer against liability incurred in such capacity,
including acting at the Corporation's request as director or officer of another
corporation, to the extent permitted or required by the CBCA. The Corporation
has agreed to contractually indemnify each director and certain officers of the
Corporation against liability resulting from any civil, criminal or

Corporation; and (ii) had reasonable grounds for believing his or her conduct

G.   SPECIAL BUSINESS TO BE TRANSACTED AT THE MEETING

1.   Background

In conjunction with the annual business of the Meeting, Mitel proposes to:

     o   Change the number of directors to a minimum of three (3) and a
         maximum of fifteen (15) with a fixed number of directors as the
         directors may from time to time determine;

     o   Change the name of the Corporation to Mitel Corporation;

     o   Authorize and approve the Corporation's 2006 Equity Incentive Plan;
         and

     o   Confirm amendments to By-law No. 1A.

2.   Interests Of Persons In Matters To Be Acted Upon

Dr. Terence H. Matthews, the Chairman of the Corporation, has a controlling
interest, directly or indirectly, in the Corporation by way of his holdings of
approximately 60% of the Series B Shares and his holdings in Wesley Clover


                                    - 13 -


Corporation and CTJL, which hold approximately 77% and 4%, respectively, of the
outstanding Common Shares of the Corporation.

3.   Special Resolution No. 1 - Change Number of Directors

The articles of the Corporation provide that the board of directors is to
consist of a minimum of one (1) and a maximum of ten (10) directors with such
fixed number of directors as determined from time to time by the Shareholders
and permit the directors to appoint additional directors in accordance with the
CBCA. The number of directors of the Corporation was previously fixed at eight
by a shareholders resolution dated July 15th, 2004, and currently, there are
seven directors on the board of directors.

In connection with an initial public offering, the Corporation will become a
"distributing corporation" for purposes of the CBCA and a "distributing
corporation" is required to have a minimum of three directors. Shareholders are
therefore being asked to consider, and if thought fit, approve Special
Resolution No. 1 to increase the minimum number of directors from one (1) to
three (3). At the same time, Shareholders are being asked to consider, and if
thought fit, approve an increase in the maximum number of directors from ten
(10) to fifteen (15) in order to support any future increases in the size of the
board of directors.

Shareholders are also being asked to consider, and if thought fit, approve an
amendment to the articles to authorize the directors to determine, between
meetings of Shareholders, any fixed number of directors to be appointed within
the minimum and maximum number permitted. The authority to determine the number
of directors complements the directors' authority to appoint one or more
additional directors, provided the total number of directors so appointed does
not exceed one-third of the number of directors elected at the previous annual
meeting of Shareholders, in accordance with the CBCA.

The board of directors of the Corporation recommends that Shareholders vote in
favour of the special resolution to amend the articles to change the number of
directors and to authorize the directors to determine the number of directors,
attached as Schedule C to this Management Proxy Circular ("Special Resolution
No. 1").

In order to be effective, Special Resolution No. 1 must be passed, with or
without amendment, by the Shareholders voting together as a single class and
representing in the aggregate, not less than two-thirds of the votes cast (in
person or by proxy) by all such Shareholders at the Meeting. Unless the nominee
identified in the attached form of proxy is directed to do otherwise, the
nominee will vote FOR Special Resolution No. 1.

Notwithstanding such approval, the board of directors of the Corporation will be
authorized, without further approval of the Shareholders, to revoke Special
Resolution No. 1 at any time before it becomes effective in accordance with the
provisions of the CBCA.

4.    Special Resolution No. 2 - Change of Name

The Mitel name has been in use worldwide in the communications system business
for over 25 years. In 2001, the Corporation acquired the communications system
business and the "Mitel" name from the corporate entity formerly called Mitel
Corporation and now called Zarlink Semiconductor Inc. The board of directors
believes that the use of the word "Networks" in the current legal name does not
properly reflect the voice centric IP-based communications solutions that the
Corporation provides. Accordingly, the board has determined that the change of
the legal name of the Corporation from "Mitel Networks Corporation" to "Mitel
Corporation" is in the best interests of the Corporation.

The board of directors of the Corporation recommends that Shareholders vote in
favour of the special resolution to amend the articles to change the name of the
Corporation, attached as Schedule D to this Management Proxy Circular ("Special
Resolution No. 2").

In order to be effective, Special Resolution No. 2 must be passed, with or
without amendment, by the Shareholders voting together as a single class and
representing in the aggregate, not less than two-thirds of the votes cast (in


                                    - 14 -


person or by proxy) by all such Shareholders at the Meeting. Unless the nominee
identified in the attached form of proxy is directed to do otherwise, the
nominee will vote FOR Special Resolution No. 2.

Notwithstanding such approval, the board of directors of the Corporation will be
authorized, without further approval of the Shareholders, to revoke Special
Resolution No. 2 at any time before it becomes effective in accordance with the
provisions of the CBCA.

5.    Ordinary Resolution No. 1 - The 2006 Equity Incentive Plan

The board of directors believes that it is in Mitel's best interests to adopt a
new equity compensation plan to replace the Corporation's existing stock option
plan. The new equity compensation plan will provide Mitel with increased
flexibility and choice in the types of compensation awards that Mitel may grant,
including options, deferred share units, restricted stock units, performance
share units and other share-based awards. The principal purpose of the proposed
2006 Equity Incentive Plan (the "Plan") is to advance the interests of Mitel by
assisting Mitel in attracting, retaining and motivating key employees,
directors, officers and consultants through performance related incentives,
thereby advancing the interests of Mitel and its shareholders. If the new Plan
is approved, the Corporation expects that no new options will be granted under
the existing stock option plan and all future awards will be granted under the
new Plan. All existing options that have been previously granted under the
existing stock option plan will continue to be governed under such existing
stock option plan

You are encouraged to read the Plan, as approved by the board of directors of
the Corporation, which is attached as Appendix E-1 to Schedule E hereto.

The aggregate number of common shares that may be issued under the Plan is 12%
of the total number of common shares outstanding from time to time. The Plan
contains an amendment provision that allows the board of directors to amend the
Plan for a number of purposes without notice or subsequent shareholder approval
including:

     o   to amend general vesting provisions;

     o   to amend the term of any option, subject to limits contained in the
         Plan;

     o   to amend the provisions in the Plan dealing with retirement, death,
         disability or termination of participant;

     o   to make amendments for the protection of participants in the Plan,
         including amendments resulting from changes in law in any
         jurisdiction; and

     o   to make amendments to cure or correct ambiguities, defects or
         mistakes in the Plan.

If Ordinary Resolution No. 1 is approved by shareholders, no subsequent
shareholder approval will be required for the board of directors to make these
types of amendments to the Plan in the future.

The board of directors of the Corporation recommends that Shareholders vote in
favour of the ordinary resolution to approve the Plan, attached as Appendix E-1
to Schedule E to this Management Proxy Circular ("Ordinary Resolution No. 1").

In order to be effective, Ordinary Resolution No. 1 must be passed, with or
without amendment, by the Shareholders voting together as a single class and
representing in the aggregate, not less than a majority of the votes cast (in
person or by proxy) by all such Shareholders at the Meeting. Unless the nominee
identified in the attached form of proxy is directed to do otherwise, the
nominee will vote FOR Ordinary Resolution No. 1.

Notwithstanding such approval, the board of directors of the Corporation will be
authorized, without further approval of the Shareholders, to revoke Ordinary
Resolution No. 1 at any time before it becomes effective in accordance with the
provisions of the CBCA.


                                    - 15 -


6.   Ordinary Resolution No. 2 - By-Law Amendments

At the Meeting, Shareholders will be asked to confirm amendments to By-law No.
1A. By-law No. 1A was enacted by the directors and confirmed by the shareholders
in 2004. The amendments to By-law No. 1A have been approved by the board of
directors and reflect Mitel's corporate governance structure and enhanced
practices including an increase in the quorum requirement for meetings of
shareholders as well as current provisions of the CBCA. A copy of the By-law
amendments, blacklined against the existing By-law No. 1A is attached as
Schedule F to this Circular.

The board of directors of the Corporation recommends that Shareholders vote in
favour of the ordinary resolution to approve the By-law Amendments, attached as
Schedule F to this Management Proxy Circular ("Ordinary Resolution No. 2").

In order to be effective, Ordinary Resolution No. 2 must be passed, with or
without amendment, by the Shareholders voting together as a single class and
representing in the aggregate, not less than a majority of the votes cast (in
person or by proxy) by all such Shareholders at the Meeting. Unless the nominee
identified in the attached form of proxy is directed to do otherwise, the
nominee will vote FOR Ordinary Resolution No. 2.

Notwithstanding such approval, the board of directors of the Corporation will be
authorized, without further approval of the Shareholders, to revoke Ordinary
Resolution No. 2 at any time before it becomes effective in accordance with the
provisions of the CBCA.

7.   Other Matters

Management of the Corporation knows of no amendment or variation to the matters
referred to in the Notice of Meeting and of no other business to be brought
before the Meeting. If any amendment, variation or other business is properly
brought before the Meeting, the form of proxy confers discretion on the persons
named on the form of proxy to vote on any amendment or variation of the matters
referred to in the notice of Meeting or any other business in accordance with
their best judgment.

The CBCA provides that, in certain circumstances, eligible shareholders are
entitled to submit to the Corporation notice of a matter that such shareholder
proposes to raise at a meeting of shareholders. The final date by which the
Corporation must receive such a proposal to be raised at the next annual meeting
of shareholders of the Corporation (subsequent to this meeting) is May 17th,
2007. Any eligible shareholder who may wish to exercise this right should
carefully consider whether they are eligible to make such a proposal, and comply
with the relevant provisions of the CBCA.

       (d)  make all other determinations and take all other actions necessary
            or advisable for the implementation and administration of this

The Board's determinations and actions within its authority under this Plan are
conclusive and binding on the Company and all other persons. The day-to-day
administration of the Plan may be delegated to such officers and employees of
the Company or of a Subsidiary as the Board determines.

3.2    Delegation to Committee

To the extent permitted by applicable law and the Company's articles, the Board
may, from time to time, delegate to a committee (the "Committee") of the Board
all or any of the powers conferred on the Board under the Plan. In connection
with such delegation, the Committee will exercise the powers delegated to it by
the Board in the manner and on the terms authorized by the Board. Any decision
made or action taken by the Committee arising out of or in connection with the
administration or interpretation of this Plan in this context is final and
conclusive. Notwithstanding any such delegation or any reference to the
Committee in this Plan, the Board may also take any action and exercise any
powers that the Committee is authorized to take or has power to exercise under
this Plan. To the extent applicable in respect of certain Awards granted to a
Participant who is a Covered Employee, such Committee shall be composed of not
less than two directors of the Company, neither of whom shall be employees of
the Company or its Affiliates and each of whom shall otherwise be "outside
directors" for the purposes of Section 162(m) of the Code. To the extent the
Company is no longer a "foreign private issuer" as defined in Exchange Act Rule
3b-4 and wishes to have a "Qualified Plan" as defined in Rule 16b-3(b)(4), such
Committee shall be composed of not less than two directors of the Company, each
of whom are "non-employee directors" for purposes of Section 16 of the Exchange
Act and Rule 16b-3 thereunder.

3.3    Eligibility

All Participants and Director Participants are eligible to participate in the
Plan, subject to subsections 9.1(e) and 9.2(g). Eligibility to participate does
not confer upon any Participant or Director Participant any right to receive any
grant of an Award pursuant to the Plan. The extent to which any Participant or
Director Participant is entitled to receive a grant of an Award pursuant to the
Plan will be determined in the sole and absolute discretion of the Committee,
provided however that the following restrictions shall also apply to this Plan,
together with all other Security Based Compensation Arrangements of the Company:

       (a)  the number of Common Shares issuable to Insiders, at any time,
            under all Security Based Compensation Arrangements, shall not
            exceed 10% of issued and outstanding Common Shares;

       (b)  the number of Common Shares issued to Insiders, within any one
            year period, under all Security Based Compensation Arrangements,
            shall not exceed 10% of issued and outstanding Common Shares; and

       (c)  no Awards shall be granted under this Plan to Dr. Terence H.
            Matthews or any of his Associates.

If the Company repurchases Common Shares for cancellation such that the tests in
Section 3.3(a) or (b) are not met following such repurchase, this shall not
constitute non-compliance under the Plan for any Awards then outstanding.

3.4    Total Common Shares Available

       (a)  The aggregate number of Common Shares that may be issued for all
            purposes pursuant to the Plan and all other Security Based
            Compensation Arrangements must not exceed 12% of the total number
            of Common Shares issued and outstanding from time to time. No
            grant may be made under the Plan if such grant would result in the
            issuance of Common Shares in excess of the above-noted limit.
            Subject to applicable law, the requirements of any stock exchange
            upon which the Common Shares may then be listed and any
            shareholder or other approval which may be required, the Board may
            in its discretion amend the Plan to increase such limit without
            notice to any Participants. If the Company repurchases Common
            Shares for cancellation such that the 12%



                                    - 29 -


            limit is exceeded following such repurchase, this shall not
            constitute non-compliance under the Plan for any Awards then
            outstanding.

       (b)  For purposes of computing the total number of Common Shares
            available for grant under the Plan, Common Shares subject to any
            Award (or any portion thereof) that has expired or is forfeited,
            surrendered, cancelled or otherwise terminated prior to the
            issuance or transfer of such Common Shares and Common Shares
            subject to an Award (or portion thereof) that is settled in cash
            in lieu of settlement in Common Shares shall again be available
            for grant under the Plan.

3.5    Award Agreements

All grants of Awards under this Plan will be evidenced by Award Agreements.
Award Agreements will be subject to the applicable provisions of this Plan and
will contain such provisions as are required by this Plan and any other
provisions that the Committee may direct. Any one officer of the Company is
authorized and empowered to execute and deliver, for and on behalf of the
Company, an Award Agreement to each Participant or Director Participant granted
an Award pursuant to this Plan.

3.6    Conditions of Grant

Each Participant or Director Participant will, when requested by the Company,
sign and deliver all such documents relating to the granting of Awards or
exercise of Options which the Company deems necessary or desirable.

3.7    Non-transferability of Awards

Subject to Section 9.1, Awards granted under this Plan may only be exercised
during the lifetime of the Participant or Director Participant by such
Participant or Director Participant personally. No assignment or transfer of
Awards, whether voluntary, involuntary, by operation of law or otherwise, vests
any interest or right in such Awards whatsoever in any assignee or transferee
(except that a Participant or Director Participant may transfer Awards to
Permitted Assigns) and immediately upon any assignment or transfer, or any
attempt to make the same, such Awards will terminate and be of no further force
or effect. If any Participant or Director Participant has transferred Awards to
a corporation pursuant to this Section 3.7, such Awards will terminate and be of
no further force or effect if at any time the transferor should cease to own all
of the issued shares of such corporation.


                                  ARTICLE 4
                               GRANT OF OPTIONS

4.1    Grant of Options

The Committee may, from time to time, subject to the provisions of this Plan and
such other terms and conditions as the Committee may prescribe, grant Options to
any Participant or any Director Participant, provided that the number of Common
Shares issuable to Director Participants shall not exceed the limits set out in
Schedule C.

4.2    Exercise Price

The Exercise Price will be as determined by the Committee but in any event will
be no less than the Fair Market Value on the Date of Grant.

4.3    Term of Options

Subject to any accelerated termination as permitted by the Committee or as
otherwise set forth in this Plan, each Option, unless otherwise specified by the
Committee, expires on the fifth (5th) anniversary of the Date of Grant (provided
that if such expiry would otherwise be during or immediately after a Black Out
Period, then the expiry shall be extended until ten (10) Business Days following
the expiration of the Black Out Period); provided that in no event will the
Exercise Period of an Option exceed ten (10) years from its Date of Grant.


                                    - 30 -


The Committee shall have the authority to condition the grant or vesting of
Options upon the attainment of specified Performance Goals, or such other
factors (which may vary as between Options) as the Committee may determine in
its sole discretion.

4.4    Exercise of Options

Unless otherwise specified by the Committee at the time of granting an Option
and except as otherwise provided in this Plan, each Option will vest and be
exercisable as follows:

Percentage of Total
Number of Common Shares
that may be Purchased                      Exercisable At Any Time
------------------------                   -----------------------
       First 25%                From the first anniversary of the Date of Grant
       Second 25%               From the second anniversary of the Date of Grant
       Third 25%                From the third anniversary of the Date of Grant
       Last 25%                 From the fourth anniversary of the Date of Grant



Once an instalment vests and becomes exercisable, it remains exercisable until
expiration or termination of the Option, unless otherwise specified by the
Committee in connection with the grant of such Option or otherwise as specified
herein. Each Option may be exercised at any time or from time to time, in whole
or in part, for up to the total number of Common Shares with respect to which it
is then exercisable. The Committee has the right to accelerate the date upon
which any instalment of any Option becomes exercisable.

Subject to the provisions of this Plan and any Award Agreement, Options shall be
exercised by means of a fully completed Exercise Notice delivered to the
Company.

4.5    Payment of Exercise Price

The Exercise Notice must be accompanied by payment in full of the Exercise Price
in respect of the Common Shares to be purchased. The Exercise Price must be
fully paid by cash, certified cheque, bank draft or money order payable to the
Company. No Common Shares will be issued or transferred until full payment
therefor has been received by the Company. As soon as practicable after receipt
of any Exercise Notice and full payment of the Exercise Price, the Company will
deliver to the Participant or Director Participant, as the case may be, a
certificate or certificates representing the acquired Common Shares.

4.6    Incentive Stock Options

The following provisions will apply only to Incentive Stock Options granted
under the Plan:

       (a)  No Incentive Stock Option may be granted to any Employee
            Participant who, at the time such Option is granted, (i) is not an
            employee of the Company or a Subsidiary or (ii) owns securities
            possessing more than ten percent (10%) of the total combined
            voting power of all classes of securities of the Company or of any
            Subsidiary, except that with respect to provision (ii) hereof such
            an Option may be granted to such an Employee if, at the time the
            Option is granted, the exercise price is at least one hundred ten
            percent (110%) of the Fair Market Value of the Common Shares
            subject to the Option, and the Option by its terms is not
            exercisable after the expiration of five (5) years from the date
            the Option is granted; and

       (b)  To the extent that the aggregate Fair Market Value of the Common
            Shares with respect to which Incentive Stock Options (without
            regard to this subsection) are exercisable for the first time by
            any individual during any calendar year (under all plans of the
            Company and its Affiliates) exceeds U.S. $100,000, such Options
            will be treated as Non Qualified Stock Options. This subsection
            will be applied by taking Options into account in the order in
            which they were granted. If some but not


                                    - 31 -


            all Options granted on any one day are subject to this subsection,
            then such Options will be apportioned between Incentive Stock
            Option and Non Qualified Stock Option treatment in such manner as
            the Committee will determine. The maximum number of Common Shares
            that may be issued under Incentive Stock Options granted under the
            Plan shall be equal to the number of Common Shares issued and
            outstanding as of the effective date of the Plan.

4.7    Special Rule Applicable to U.S. Taxpayers

With respect to Options granted to Participants or Director Participants who are
U.S. Taxpayers, Common Shares shall constitute "stock of the service recipient"
within the meaning of Section 409A of the Code if such Participant or Director
Participant performs services for any Affiliate that is at least fifty percent
owned by the Company.


                                  ARTICLE 5
                         GRANT OF DEFERRED SHARE UNITS

5.1    Number of Deferred Share Units

The Committee may, from time to time, subject to the provisions of this Plan and
such other terms and conditions as the Committee may prescribe, grant Deferred
Share Units to any Participant or Director Participant, provided that the number
of Deferred Share Units granted to Director Participants shall not exceed the
limits set out in Schedule C.

All Deferred Share Units received by a Participant or Director Participant shall
be credited to an account maintained for the Participant or the Director
Participant on the books of the Company, as of the Date of Grant. The award of
Deferred Share Units for a calendar year to a Participant or Director
Participant shall be evidenced by an Award Agreement.

5.2    Distribution of Deferred Share Units

A Participant or Director Participant shall receive, on the Distribution Date, a
lump sum payment in cash equal to the number of Deferred Share Units recorded in
the Participant's or Director Participant's account on the Distribution Date
multiplied by the Fair Market Value, less any applicable withholding taxes. At
the option of the Committee, the Company may settle the Deferred Share Units in
Common Shares. Upon payment in full of the value of the Deferred Share Units,
whether in cash or in Common Shares, the Deferred Share Units shall be
cancelled.

5.3    Death of Participant Prior to Distribution

Upon the death of a Participant or Director Participant prior to the
distribution of the Deferred Share Units credited to the account of such
Participant or Director Participant under the Plan, a cash payment shall be made
to the estate of such Participant on or about the thirtieth (30th) day after the
Company is notified of the death of the Participant or Director Participant or
on a later date elected by the Participant's or Director Participant's estate,
in the form prescribed for such purposes by the Company and delivered to the
Corporate Secretary no later than twenty (20) days after the Company is notified
of the death of the Participant or Director Participant, provided that such date
is no later than the last business day of the calendar year following the
calendar year in which the Participant or Director Participant dies. Such cash
payment shall be equivalent to the amount which would have been paid to the
Participant or Director Participant pursuant to and subject to Section 5.2,
calculated on the basis that the day on which the Participant or Director
Participant dies, or the date elected by the estate, as applicable, is the
Distribution Date. Upon payment in full of the value of all of the Deferred
Share Units that become payable under this Section 5.3, the Deferred Share Units
shall be cancelled.

                                  ARTICLE 6
                        GRANT OF RESTRICTED SHARE UNITS

6.1    Grant of RSUs

The Committee may, from time to time, subject to the provisions of this Plan and
such other terms and conditions as the Committee may prescribe, grant RSUs to
any Participant or any Director Participant, provided that the number of RSUs
issuable to Director Participants shall not exceed the limits set out in
Schedule C.

6.2    Terms of RSUs

The Committee shall have the authority to condition the grant of RSUs upon the
attainment of specified Performance Goals, or such other factors (which may vary
as between awards of RSUs) as the Committee may determine in its sole
discretion.

6.3    Vesting of RSUs

The Committee shall have the authority to determine at the time of grant, in its
sole discretion, the duration of the vesting period and other vesting terms
applicable to the grant of RSUs, provided that no RSU granted shall vest and be
payable after December 31 of the third calendar year following the year of
service for which the RSU was granted.

6.4    Share Certificates

Unless otherwise specified in the Award Agreement, as soon as practicable
following the expiry of the applicable vesting period, or at such later date as
may be determined by the Committee in its sole discretion, a share certificate
representing the Common Shares issuable pursuant to the RSUs shall be registered
in the name of the Participant or as the Participant may direct, subject to
applicable securities laws.


                                   ARTICLE 7
                            PERFORMANCE SHARE UNITS

7.1    Grant of Performance Share Units

The Committee may, from time to time, subject to the provisions of this Plan and
such other terms and conditions as the Committee may prescribe, grant
Performance Share Units to any Participant. Each Performance Share Unit will
consist of a right, (i) denominated or payable in cash, Common Shares, other
securities or other property, and (ii) which will confer on the holder thereof
rights valued as determined by the Committee and payable to, or exercisable by,
the holder of the Performance Share Unit, in whole or in part, upon the
achievement of such Performance Goals during such performance periods as the
Committee will establish.

7.2    Value of Performance Share Units

The initial value of a Performance Share Unit will be established by the
Committee at the Date of Grant and, to the extent related to Common Shares,
other securities or other property will initially be equal to 100% of the Fair
Market Value of a Common Share or the fair market value (as determined by the
Board) of such other security or such other property on the Date of Grant.

7.3    Terms of Performance Share Units

Subject to the terms of the Plan and any applicable Award Agreement, the
Performance Goals to be achieved during any performance period, the length of
any performance period, the amount of any Performance Share Unit granted, the
termination of a Participant's employment and the amount of any payment or
transfer to be made pursuant to any Performance Share Unit will be determined by
the Committee and by the other terms and conditions of any Performance Share
Unit.


                                    - 33 -


7.4    Performance Goals

The Committee will issue Performance Goals prior to the commencement of the
performance period to which such Performance Goals pertain. The Performance
Goals may be based upon the achievement of corporation-wide, divisional or
individual goals, or any other basis determined by the Committee. The Committee
may modify the Performance Goals as necessary to align them with the Company's
corporate objectives if there is a subsequent material change in the Company's
business, operations or capital or corporate structure. Notwithstanding the
foregoing, to the extent deemed desirable by the Committee, in the case of a
Covered Employee, the Performance Goals set forth in Section 2.1 shall apply.


                                  ARTICLE 8
                           OTHER SHARE-BASED AWARDS

8.1    Other Share-Based Awards

The Committee may, from time to time, subject to the provisions of this Plan and
such other terms and conditions as the Committee may prescribe, grant Other
Share-Based Awards to any Participant. Each Other Share-Based Award will consist
of a right (1) which is other than an Award or right described in Article 4, 5,
6 or 7 above and (2) which is denominated or payable in, valued in whole or in
part by reference to, or otherwise based on or related to, Common Shares
(including, without limitation, securities convertible into Common Shares) as
are deemed by the Committee to be consistent with the purposes of the Plan;
provided, however, that such right will comply with applicable law. Subject to
the terms of the Plan and any applicable Award Agreement, the Committee will
determine the terms and conditions of Other Share-Based Awards. Common Shares or
other securities delivered pursuant to a purchase right granted under this
Section 8.1 will be purchased for such consideration, which may be paid by such
method or methods and in such form or forms, including, without limitation,
cash, Common Shares, other securities, other Awards, other property, or any
combination thereof, as the Committee will determine.


                                  ARTICLE 9
                           TERMINATION OF EMPLOYMENT

9.1    Retirement, Death or Disability

Subject to Section 5.3, if a Participant or Director Participant dies or becomes
Disabled while an employee, officer or director of or consultant to the Company
or an Affiliate or if the employment or term of office or engagement of a
Participant with the Company or an Affiliate terminates due to Retirement:

       1.   the executor or administrator of the Participant's or Director
            Participant's estate or the Participant or Director Participant,
            as the case may be, may exercise Options of the Participant or
            Director Participant. The number of Options exercisable shall
            equal:

                (i)   the number of Options that were exercisable at the
                      Termination Date; plus

                (ii)  a portion of the next instalment of the Options due to
                      vest equal to the number of Options next due to vest
                      multiplied by a fraction the numerator of which is the
                      number of days elapsed since the date of vesting of the
                      last instalment of the Options (or if none have vested,
                      the Date of Grant) to the Termination Date and the
                      denominator of which is the number of days between the
                      date of vesting of the last instalment of the Option (or
                      if none have vested, the Date of Grant) and the date of
                      vesting of the next instalment of the Option;

       2.   the right to exercise such Options terminates on the earlier of:
            (i) the date that is twelve months after the Termination Date
            (except that in the case of Retirement of a U.S. Taxpayer, any
            Incentive Stock Option shall expire on the date that is three
            months after the


                                    - 34 -


            Termination Date); and (ii) the date on which the Exercise Period
            of the particular Option expires. Subject to subsection (a), any
            Options held by the Participant or Director Participant that are
            not yet exercisable at the Termination Date immediately expire and
            are cancelled on the Termination Date;

       3.   a portion of the next instalment of any other Awards due to vest
            shall immediately vest, such portion to equal to the number of
            Awards next due to vest multiplied by a fraction the numerator of
            which is the number of days elapsed since the date of vesting of
            the last instalment of the Awards (or if none have vested, the
            Date of Grant) to the Termination Date and the denominator of
            which is the number of days between the date of vesting of the
            last instalment of the Awards (or if none have vested, the Date of
            Grant) and the date of vesting of the next instalment of the
            Awards;

       4.   subject to subsection (c), any other Awards held by the
            Participant or Director Participant that are not yet vested at the
            Termination Date are immediately forfeited to the Company on the
            Termination Date; and

       5.   such Participant's or Director Participant's eligibility to
            receive further grants of Awards under the Plan ceases as of the
            Termination Date.

9.2    Termination of Employment or Services

       (a)  Where a Participant's or Director Participant's employment or term
            of office or engagement with the Company or an Affiliate
            terminates by reason of the Participant's death, Disability or
            Retirement or, in the case of a Director Participant, the Director
            Participant's death or Disability, then the provisions of Section
            9.1 will apply.

       (b)  Where a Participant's employment or term of office or engagement
            terminates by reason of a Participant's resignation, then any
            Options held by the Participant that are exercisable at the
            Termination Date continue to be exercisable by the Participant
            until the earlier of: (A) the date that is 30 days after the
            Termination Date; and (B) the date on which the Exercise Period of
            the particular Option expires. Any Options held by the Participant
            that are not yet exercisable at the Termination Date immediately
            expire and are cancelled on the Termination Date, and any other
            Awards held by the Participant that are not yet vested at the
            Termination Date are immediately forfeited to the Company on the
            Termination Date.

       (c)  Where a Participant's employment or term of office or engagement
            terminates by reason of termination by the Company or an Affiliate
            without cause (as determined by the Committee in its sole
            discretion) (whether such termination occurs with or without any
            or adequate notice or reasonable notice, or with or without any or
            adequate compensation in lieu of such notice), then any Options
            held by the Participant that are exercisable at the Termination
            Date continue to be exercisable by the Participant until the
            earlier of: (A) the date that is 90 days after the Termination
            Date; and (B) the date on which the Exercise Period of the
            particular Option expires. Any Options held by the Participant
            that are not yet exercisable at the Termination Date immediately
            expire and are cancelled on the Termination Date, and any other
            Awards held by the Participant that are not yet vested at the
            Termination Date are immediately forfeited to the Company on the
            Termination Date.

       (d)  Where a Participant's employment or term of office or engagement
            is terminated by the Company or an Affiliate for cause (as
            determined by the Committee in its sole discretion), or, in the
            case of a Consultant Participant, for breach of contract (as
            determined by the Committee in its sole discretion), then any
            Options held by the Participant at the Termination Date (whether
            or not exercisable) immediately expire and are cancelled on the
            Termination Date, and any other Awards held by the Participant at
            the Termination Date (whether or not vested) are immediately
            forfeited to the Company on the Termination Date.



                                    - 35 -


       (e)  Where a Director Participant's term of office is terminated by the
            Company for breach by the Director Participant of his or her
            fiduciary duty to the Company (as determined by the Committee in
            its sole discretion), then any Options held by the Director
            Participant at the Termination Date (whether or not exercisable)
            immediately expire and are cancelled on the Termination Date, and
            any other Awards held by the Director Participant at the
            Termination Date (whether or not vested) are immediately forfeited
            to the Company on the Termination Date.

       (f)  Where a Director Participant's term of office terminates for any
            reason other than death or Disability of the Director Participant
            or a breach by the Director Participant of his or her fiduciary
            duty to the Company (as determined by the Committee in its sole
            discretion), the Committee or the Board may, in its sole
            discretion, at any time prior to or following the Termination
            Date, (A) permit the exercise of any or all Options held by the
            Director Participant, whether or not exercisable at the
            Termination Date, in the manner and on the terms authorized by the
            Board, provided that neither the Committee nor the Board shall, in
            any case, authorize the exercise of an Option pursuant to this
            Section beyond the date on which the Exercise Period of the
            particular Option expires; and (B) provide for the vesting of any
            or all other Awards held by a Director Participant on the
            Termination Date.

       (g)  The eligibility of a Participant or Director Participant to
            receive further grants under the Plan ceases as of the date that
            the Company or an Affiliate, as the case may be, provides the
            Participant or Director Participant with written notification that
            the Participant's employment or term of office, or the Director
            Participant's term of office, as the case may be, is terminated,
            notwithstanding that such date may be prior to the Termination
            Date.

       (h)  Unless the Committee, in its sole discretion, otherwise
            determines, at any time and from time to time, Awards are not
            affected by a change of employment arrangement within or among the
            Company or a Subsidiary for so long as the Participant continues
            to be an employee of the Company or a Subsidiary, including
            without limitation a change in the employment arrangement of a
            Participant whereby such Participant becomes a Director
            Participant.

9.3    Discretion to Permit Exercise

Notwithstanding the provisions of Sections 9.1 and 9.2, the Committee may, in
its discretion, at any time prior to or following the events contemplated in
such Sections, permit the exercise of any or all Options held by a Participant
or Director Participant or permit the acceleration of vesting of any or all RSUs
or other Awards, all in the manner and on the terms as may be authorized by the
Committee, provided that the Committee will not, in any case, authorize the
exercise of an Option pursuant to this Section beyond the expiration of the
Exercise Period of the particular Option.

9.4    Incentive Stock Options

Notwithstanding anything to the contrary in this Article 9, in the case of an
Incentive Stock Option, any Incentive Stock Options held by a U.S. Taxpayer that
are exercisable at the Termination Date continue to be exercisable by the U.S.
Taxpayer until the earlier of: (A) the date that is three months after the
Termination Date; (B) the date on which the Exercise Period of the particular
Incentive Stock Option expires, or (C) any shorter post-Termination Date
exercise period as is set forth in this Article 9 or in the U.S. Taxpayer's
Award Agreement.


                                  ARTICLE 10
                               CHANGE IN CONTROL

10.1   Change in Control

       (a)  Unless otherwise determined by the Committee or the Board at or
            after the Date of Grant, any Options outstanding immediately prior
            to the occurrence of a Change in Control,



                                    - 36 -


            but which are not then exercisable, shall become fully exercisable
            upon the occurrence of a Change in Control. Unless otherwise
            determined by the Committee or the Board at or after the Date of
            Grant, all outstanding vested Options shall be cashed out at the
            Change in Control Price, less the applicable Exercise Price for
            such Options, as of the date such Change in Control is determined
            to have occurred, or as of such other date as the Committee or the
            Board may determine prior to the Change in Control. Outstanding
            Options may only be cashed out, as described above, if the Change
            in Control Price is higher than the Exercise Price for such
            outstanding Options. If the Change in Control Price is equal to or
            lower than the Exercise Price for such outstanding Options, the
            Committee or the Board may terminate such outstanding Options and
            such outstanding Options shall be of no further force or effect
            Further, the Committee or the Board shall have the right to
            provide for the conversion or exchange of any outstanding Options
            into or for options, rights or other securities in any entity
            participating in or resulting from the Change in Control. In
            addition, and notwithstanding Section 12.7(b), the Committee or
            the Board shall have the right to determine, its sole discretion,
            that Options outstanding, but which are not then exercisable,
            shall not become exercisable and shall be cancelled in the event
            of a Change in Control.

       (b)  Unless otherwise determined by the Committee or the Board at or
            after the Date of Grant, any Restricted Share Units, Deferred
            Share Units, Performance Share Units or Other Share-Based Awards
            outstanding immediately prior to the occurrence of a Change in
            Control shall become fully vested upon the occurrence of a Change
            in Control. Unless otherwise determined by the Committee or the
            Board at or after the Date of Grant, any Restricted Share Unit,
            Deferred Share Unit, Performance Share Unit or Other Share-Based
            Award outstanding immediately prior to the occurrence of a Change
            in Control shall be cashed out at the Change in Control Price as
            of the date such Change in Control is deemed to have occurred, or
            as of such other date as the Committee or the Board may determine
            prior to the Change in Control. Further, the Committee or the
            Board shall have the right to provide for the conversion or
            exchange of any Restricted Stock Unit, Deferred Stock Unit,
            Performance Share Unit or Other Share-Based Award into or for
            rights or other securities in any entity participating in or
            resulting from the Change in Control. In addition, and
            notwithstanding Section 12.7(b), the Committee or the Board shall
            have the right to determine, in its sole discretion, that
            Restricted Stock Units, Deferred Stock Units, Performance Share
            Units or Other Share-Based Awards outstanding shall not become
            vested and shall be cancelled and forfeited to the Company in the
            event of a Change in Control.

10.2   Parachute Payments

If a Participant or Director Participant is entitled to receive payments that
would qualify as excess "parachute payments" under Section 280G of the Code,
those payments shall be reduced by the necessary amount so that the Participant
or Director Participant is not subject to excise tax under Section 4999 of the
Code if such reduction would result in the Participant or Director Participant
receiving a greater after-tax payment.


                                  ARTICLE 11
                           SHARE CAPITAL ADJUSTMENTS

11.1   General

The existence of any Awards does not affect in any way the right or power of the
Company or its shareholders to make, authorize or determine any adjustment,
recapitalization, reorganization or any other change in the Company's capital
structure or its business, or any amalgamation, combination, arrangement, merger
or consolidation involving the Company, to create or issue any bonds,
debentures, Common Shares or other securities of the Company or to determine the
rights and conditions attaching thereto, to effect the dissolution or
liquidation of the Company or any sale or transfer of all or any part of its
assets or business, or to effect any other corporate act or proceeding, whether
of a similar character or otherwise, whether or not any such action referred to
in this Section would have an adverse effect on this Plan or on any Award
granted hereunder.


                                    - 37 -


11.2     Reorganization of Company's Capital

Should the Company effect a subdivision or consolidation of Common Shares or any
similar capital reorganization or a payment of a stock dividend (other than a
stock dividend that is in lieu of a cash dividend), or should any other change
be made in the capitalization of the Company that does not constitute a Change
in Control and that would warrant the amendment or replacement of any existing
Awards in order to adjust: (a) the number of Common Shares that may be acquired
on the vesting of outstanding Awards or the exercise of any outstanding Options;
and/or (b) the Exercise Price of any outstanding Options and/or (c) the terms of
any other Award in order to preserve proportionately the rights and obligations
of the Participants or Director Participants holding such Awards, the Board will
authorize such steps to be taken as it may consider to be equitable and
appropriate to that end.

11.3   Other Events Affecting the Company

In the event of an amalgamation, combination, arrangement, merger or other
transaction or reorganization involving the Company and occurring by exchange of
Common Shares, by sale or lease of assets or otherwise, that does not constitute
a Change in Control and that warrants the amendment or replacement of any
existing Awards in order to adjust: (a) the number of Common Shares that may be
acquired on the vesting of outstanding Awards or the exercise of any outstanding
Options; or (b) the Exercise Price of any outstanding Options and/or (c) the
terms of any other Award in order to preserve proportionately the rights and
obligations of the Participants or Director Participants holding such Awards,
the Board will authorize such steps to be taken as it may consider to be
equitable and appropriate to that end.

11.4    Immediate Exercise of Awards

Where the Board determines that the steps provided in Sections 11.2 and 11.3
would not preserve proportionately the rights, value and obligations of the
Participants or Director Participants holding such Awards in the circumstances
or otherwise determines that it is appropriate:

       (a)  the Board may permit the immediate exercise of any outstanding
            Options that are not otherwise exercisable, and the immediate
            vesting of any unvested Awards; and

       (b)  if the Board takes the step contemplated in (a) above, the Board
            may also authorize the Company, to the extent permitted under
            applicable laws, to:

                (i)   purchase any Options from any Participant or Director
                      Participants for a price equal to the difference between
                      the Fair Market Value of the underlying Common Shares
                      and the Exercise Price of the Options; or

                (ii)  lend to Participants an amount equal to the aggregate
                      Exercise Price for those Options of the Participant
                      which have an Exercise Price which is less than the Fair
                      Market Value of the underlying Common Shares at a rate
                      of interest equal to the current prime rate plus one
                      percent provided that the Participant irrevocably:

                      (A)   agrees to exercise all such Options of the
                            Participant; and

                      (B)   authorizes the Company to sell, dispose of
                            or deposit in acceptance of an outstanding
                            take-over bid the Common Shares issuable
                            upon the exercise of such Options, to deduct
                            from the proceeds of sale of such Common
                            Shares an amount equal to the outstanding
                            balance of the loan plus accrued interest in
                            payment of such loan, to mail a cheque
                            payable to the Participant for the balance
                            of the proceeds of sale and to execute and
                            deliver on behalf of the Participant all
                            transfers, consents or other documents
                            necessary to give effect to the foregoing.


                                    - 38 -


11.5   Issue by Company of Additional Shares

Except as expressly provided in this Article 11, neither the issue by the
Company of shares of any class or securities convertible into or exchangeable
for shares of any class, nor the conversion or exchange of such shares or
securities, affects, and no adjustment by reason thereof is to be made with
respect to: (a) the number of Common Shares that may be acquired as a result of
a grant of Awards or upon the exercise of any outstanding Options; or (b) the
Exercise Price of any outstanding Options.

11.6   Fractions

No fractional Common Shares will be issued on the exercise of an Option or the
grant of an Award. Accordingly, if, as a result of any adjustment under Section
11.2 or 11.3, a Participant or Director Participant would become entitled to a
fractional Common Share, the Participant or Director Participant has the right
to acquire only the adjusted number of full Common Shares and no payment or
other adjustment will be made with respect to the fractional Common Shares which
shall be disregarded.


                                  ARTICLE 12
                           MISCELLANEOUS PROVISIONS

12.1   Legal Requirement

The Company is not obligated to grant any Awards, issue any Common Shares or
other securities, make any payments or take any other action if, in the opinion
of the Board, in its sole discretion, such action would constitute a violation
by a Participant, Director Participant or the Company of any provision of any
applicable statutory or regulatory enactment of any government or government
agency or the requirements of any stock exchange upon which the Common Shares
may then be listed.

12.2   Participants' Entitlement

Except as otherwise provided in this Plan, Options (whether or not exercisable)
and other Awards previously granted under this Plan are not affected by any
change in the relationship between, or ownership of, the Company and an
Affiliate. For greater certainty, all grants of Awards remain valid and all
Options remain valid and exercisable in accordance with the terms and conditions
of this Plan and are not affected by reason only that, at any time, an Affiliate
ceases to be an Affiliate.

12.3   Withholding Taxes

The granting or vesting of each Award and exercise of each Option granted under
this Plan is subject to the condition that if at any time the Committee
determines, in its discretion, that the satisfaction of withholding tax or other
withholding liabilities is necessary or desirable in respect of such grant,
vesting or exercise, such exercise is not effective unless such withholding has
been effected to the satisfaction of the Committee. In such circumstances, the
Committee may require that a Participant or Director Participant pay to the
Company, in addition to and in the same manner as the Exercise Price, or as the
Committee may determine, such amount as the Company or an Affiliate is obliged
to remit to the relevant taxing authority in respect of the granting or vesting
of the Award or exercise of the Option. Any such additional payment is due no
later than the date on which any amount with respect to the Award or exercised
Option is required to be remitted to the relevant tax authority by the Company
or an Affiliate, as the case may be.

12.4   Rights of Participant

No Participant or Director Participant has any claim or right to be granted an
Award (including, without limitation, an Option granted in substitution for any
Option that has expired pursuant to the terms of this Plan) and the granting of
any Award is not to be construed as giving a Participant or Director Participant
a right to remain as an employee, consultant or director of the Company or an
Affiliate. No Participant or Director Participant has any rights as a
shareholder of the Company in respect of Common Shares issuable


                                    - 39 -


on the exercise of any Option or issuable pursuant to any other Award until
the allotment and issuance to such Participant or Director Participant of
certificates representing such Common Shares.

12.5   Other Incentive Awards

The Committee shall have the right to grant other incentive awards based upon
Common Shares under this Plan to Participants or Director Participants in
accordance with applicable laws and regulations and subject to regulatory
approval, including without limitation the approval of the Toronto Stock
Exchange, having such terms and conditions as the Committee may determine,
including without limitation the grant of Common Shares based upon certain
conditions and the grant of securities convertible into Common Shares.

12.6     Termination

The Plan will terminate on the earliest of: (i) the date upon which no further
Common Shares remain available for issuance under the Plan and no Options or
other Awards remain outstanding; and (ii) the acceleration of the vesting of
Options and other Awards pursuant to Section 10.1 upon the occurrence of a
Change in Control, unless renewed for such further period and upon such terms
and conditions as the Committee may determine, but in all events the Plan will
automatically terminate on the tenth anniversary of the effective date of the
Plan.

12.7   Amendment

       (a)  Subject to the rules and policies of any stock exchange on which
            the Common Shares are listed and applicable law, the Board may,
            without notice or shareholder approval, at any time or from time
            to time, amend the Plan for the purposes of:

                (i)   making any amendments to the general vesting provisions
                      of each Option, RSU or other Award;

                (ii)  making any amendments to the general term of each Option
                      provided that no Option held by an Insider may be
                      extended beyond its original expiry date and no Option
                      may be exercised after the tenth (10th) anniversary of
                      the Date of Grant;

                (iii) making any amendments to the provisions set out in
                      Article 9;

                (iv)  making any amendments to add covenants of the Company
                      for the protection of Participants or Director
                      Participants, as the case may be, provided that the
                      Board shall be of the good faith opinion that such
                      additions will not be prejudicial to the rights or
                      interests of the Participants or Director Participants,
                      as the case may be;

                (v)   making any amendments not inconsistent with the Plan as
                      may be necessary or desirable with respect to matters or
                      questions which, in the good faith opinion of the Board,
                      having in mind the best interests of the Participants
                      and Director Participants, it may be expedient to make,
                      including amendments that are desirable as a result of
                      changes in law in any jurisdiction where a Participant
                      or Director Participant resides, provided that the Board
                      shall be of the opinion that such amendments and
                      modifications will not be prejudicial to the interests
                      of the Participants and Director Participants; or

                (vi)  making such changes or corrections which, on the advice
                      of counsel to the Company, are required for the purpose
                      of curing or correcting any ambiguity or defect or
                      inconsistent provision or clerical omission or mistake
                      or manifest error, provided that the Board shall be of
                      the opinion that such changes or corrections will not be
                      prejudicial to the rights and interests of the
                      Participants or Director Participants.


                                    - 40 -


       (b)  Subject to Section 10.1, the Board shall not alter or impair any
            rights or increase any obligations with respect to an Award
            previously granted under the Plan without the consent of the
            Participant or Director Participant, as the case may be.

       (c)  Notwithstanding any other provision of this Plan, none of the
            following amendments shall be made to this Plan without approval
            of the Toronto Stock Exchange (to the extent the Company has any
            securities listed on such exchange) and the approval of
            shareholders:

                (i)   amendments to the Plan which would increase the number
                      of Common Shares issuable under the Plan, otherwise than
                      in accordance with the terms of this Plan;

                (ii)  amendments to the Plan which would increase the number
                      of Common Shares issuable to Insiders, otherwise than in
                      accordance with the terms of this Plan;

                (iii) amendments to the Plan which would increase the number
                      of Common Shares issuable to Director Participants under
                      the Plan, otherwise than in accordance with the terms of
                      this Plan;

                (iv)  amendments that would extend the Exercise Period of any
                      Options held by Insiders beyond the Exercise Period
                      otherwise determined in accordance with this Plan;

                (v)   amendments that would reduce the Exercise Price of any
                      Options held by Insiders, otherwise than in accordance
                      with the terms of this Plan; and

                (vi)  the addition of any form of financial assistance to a
                      Participant or Director Participant.

Any amendment that would cause an Award held by a U.S. Taxpayer to fail to
comply with Section 409A of the Code shall be null and void ab initio.

12.8   Section 409A of the Code

This Plan will be construed and interpreted to comply with Section 409A of the
Code to the extent required to preserve the intended tax consequences of this
Plan. The Company reserves the right to amend this Plan to the extent it
reasonably determines is necessary in order to preserve the intended tax
consequences of this Plan in light of Section 409A of the Code and any
regulations or guidance under that section. In no event will the Company be
responsible if Awards under this Plan result in adverse tax consequences to a
U.S. Taxpayer under Section 409A of the Code. Notwithstanding any provisions of
the Plan to the contrary, in the case of any "specified employee" within the
meaning of Section 409A of the Code who is a U.S. Taxpayer, distributions of
defined compensation under Section 409A of the Code made in connection with a
"separation from service" within the meaning set forth in Section 409A of the
Code may not be made prior to the date which is 6 months after the date of
separation from service (or, if earlier, the date of death of the U.S.
Taxpayer). Any amounts subject to a delay in payment pursuant to the preceding
sentence shall be paid as soon practicable following such 6-month anniversary of
such separation from service.

12.9     Requirement of Notification of Election Under Section 83(b) of the Code

If a Participant or Director Participant, in connection with the acquisition of
Common Shares under the Plan, is permitted under the terms of the Award
Agreement to make the election permitted under Section 83(b) of the Code (i.e.,
an election to include in gross income in the year of transfer the amounts
specified in Section 83(b) of the Code notwithstanding the continuing transfer
restrictions) and the Participant or Director Participant makes such an
election, the Participant or Director Participant shall notify the Company of
such election within ten (10) days of filing notice of the election with the
Internal Revenue Service, in addition to any filing and notification required
pursuant to regulations issued under Section 83(b) of the Code.


                                    - 41 -


12.10  Requirement of Notification Upon Disqualifying Disposition Under
       Section 421(b) of the Code

If any Participant shall make any disposition of Common Shares issued pursuant
to the exercise of an Incentive Stock Option under the circumstances described
in Section 421(b) of the Code (relating to certain disqualifying dispositions),
such Participant shall notify the Company of such disposition within ten (10)
days thereof.

12.11  Indemnification

Every member of the Board will at all times be indemnified and saved harmless by
the Company from and against all costs, charges and expenses whatsoever
including any income tax liability arising from any such indemnification, that
such member may sustain or incur by reason of any action, suit or proceeding,
taken or threatened against the member, otherwise than by the Company, for or in
respect of any act done or omitted by the member in respect of this Plan, such
costs, charges and expenses to include any amount paid to settle such action,
suit or proceeding or in satisfaction of any judgment rendered therein.

12.12  Participation in the Plan

The participation of any Participant or Director Participant in the Plan is
entirely voluntary and not obligatory and shall not be interpreted as conferring
upon such Participant or Director Participant any rights or privileges other
than those rights and privileges expressly provided in the Plan. In particular,
participation in the Plan does not constitute a condition of employment or
engagement nor a commitment on the part of the Company to ensure the continued
employment or engagement of such Participant or Director Participant. The Plan
does not provide any guarantee against any loss which may result from
fluctuations in the market value of the Common Shares. The Company does not
assume responsibility for the income or other tax consequences for the
Participants and Director Participants and they are advised to consult with
their own tax advisors.

12.13  Optionee to bear cost of Employer's NICs on Option Gains

The Optionee agrees with the Company and undertakes to any other company which
is a "secondary contributor" in respect of Employer's NICs payable in respect of
any Option Gain (the "Secondary Contributor") that:

       (a)  the Secondary Contributor may recover from the Optionee the whole
            of any Employer's NIC; and

       (b)  the Optionee shall join with the Secondary Contributor in making
            an election (in such terms and such form and subject to such
            approval by the Inland Revenue as provided in paragraphs 3A and 3B
            of Schedule 1 to the Social Security Contributions and Benefits
            Act 1992) for the whole of any liability of the Secondary
            Contributor to Employer's NICs to be transferred to the Optionee.

            aggregate number of Option Shares such number of Option Shares as,
            in the opinion of the Company, will enable the Company to sell as

            expected to be obtained at the time of sale) and to pay over to
            the Optionee's Employer sufficient monies out of the net proceeds
