Ottawa, Ontario, Canada K2K2W7

Attention: Steve Spooner, Chief Financial Officer

Re:

Acquisition of Aastra Technologies Limited

Ladies and Gentlemen:

You have advised Jefferies Finance LLC (“Jefferies Finance”), The Toronto-Dominion Bank (“Toronto-Dominion”) and TD Securities (USA) LLC (“TD Securities” and, collectively with Toronto-Dominion and Jefferies Finance, the “Commitment Parties”, “we” or “us”) that Mitel Networks Corporation, a corporation organized under the federal laws of Canada (the “Acquiror” or “you”), intends to acquire, directly or indirectly, (the “Acquisition”) all of the issued and outstanding capital stock of all classes (the “Shares”) of Aastra Technologies Limited, a corporation organized under the federal laws of Canada (the “Target” and, together with its subsidiaries, the “Acquired Business”) by way of a statutory plan of arrangement (the “Arrangement”) and to refinance (together with any applicable prepayment premium or fee, with the commitments thereunder being terminated, and all guarantees and security in respect thereof being released) all of the existing funded indebtedness (the “Existing Debt”) of the Acquiror and its subsidiaries and the Acquired Business (the “Refinancing”). Capitalized terms used but not defined herein and defined in any exhibit hereto have the meanings assigned to them in such exhibit.

You have advised us that the total cash purchase price for the Acquisition (including fees, commissions and expenses and the Refinancing) (the “Purchase Price”) will be financed from the following sources:

(i) borrowings under a $50.0 million senior secured first lien revolving credit facility having the terms set forth in Exhibit A hereto (the “Revolving Credit Facility”), it being understood and agreed that no more than an amount to be mutually agreed of borrowings under the Revolving Credit Facility may be used on the Closing Date to finance the Acquisition and for the payment of fees and expenses (including upfront fees or original issue discount) payable in connection with the Facilities (as defined below), and

(ii) a $355.0 million senior secured first lien term loan facility having the terms set forth in Exhibit A hereto (the “Term Loan Facility” and, together with the Revolving Credit Facility, the “Facilities”).

The transactions described in clauses (i) and (ii) above are referred to as the “Debt Financing” and, together with the Acquisition and the Refinancing and the payment of all related fees, commissions and expenses are collectively referred to as the “Transactions.” You and your subsidiaries (including the Target and its subsidiaries) are referred to herein as the “Company.” As used in this Commitment Letter and the other Debt Financing Letters (as defined below), the words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.”

1. The Commitments.

In connection with the foregoing, (x) Jefferies Finance is pleased to inform you that it hereby commits directly or through one or more of its affiliates, to provide 50% of the Term Loan Facility and 50% of the Revolving Credit Facility and (y) Toronto-Dominion is pleased to inform you that it hereby commits directly or through one or more of its affiliates, to provide 50% of the Term Loan Facility and 50% of the Revolving Credit Facility. The commitments of Jefferies Finance and Toronto-Dominion are several and not joint.

The commitments described in this Section 1 are collectively referred to herein as the “Commitments.” Each applicable Commitment Party’s obligation to the Borrowers to fund the Facilities on the Closing Date is subject only to the specified closing conditions set forth in Section 3 of this letter (this letter, including the exhibits, schedules and annexes hereto, collectively, this “Commitment Letter”) among you and each of us and on Exhibit B and Exhibit C hereto. Notwithstanding anything to the contrary in this Commitment Letter or the fee letter dated as of the date hereof (the “Fee Letter” and, together with this Commitment Letter, the “Debt Financing Letters”), among you and each of us, except as otherwise set forth in Exhibit A, Exhibit B and Exhibit C hereto, the terms of this Commitment Letter are intended as an outline of certain of the material provisions of the Facilities, but do not include all of the terms, covenants, representations, warranties, default clauses and other provisions that will be contained in the definitive documents relating to the Debt Financing, which shall be prepared by our counsel (collectively, the “Definitive Debt Documents”); provided, that the credit agreement in respect of the Facilities shall not contain any (x) representations and warranties other than those described under the caption “Representations and Warranties” as set forth in Exhibit A hereto, (y) any affirmative, negative or financial covenants other than those described under the captions “Affirmative Covenants”, “Negative Covenants” and “Financial Covenant” as set forth in Exhibit A hereto or (z) any defaults or events of default other than those described under the caption “Events of Default” as set forth in Exhibit A hereto; and further provided that there shall be no closing condition to the Facilities contained in the Definitive Debt Documents that is not specifically set forth in Section 3 hereof or on Exhibit B or Exhibit C to this Commitment Letter. Those matters that are not covered or made clear in the Debt Financing Letters are subject to mutual agreement of each of the parties hereto. No party hereto has been authorized by us to make any oral or written statements or representations that are inconsistent with the Debt Financing Letters.

2. Titles and Roles. As consideration for the Commitments, you hereby retain and will cause your affiliates to retain (i) Jefferies Finance and TD Securities or their respective designees to act as

joint lead arrangers and joint bookrunners in connection with the Facilities (in such capacities, each an “Arranger” and, together the “Arrangers”), and (ii) Jefferies Finance or its designees to act as sole administrative agent and sole collateral agent in connection with the Facilities. It is further agreed that Jefferies Finance will have “left side” designation and shall appear on the top left of any offering or marketing materials in respect of the Facilities and shall hold the leading role and responsibilities associated with such designation, including maintaining sole “physical books” and syndication rights in respect of the Facilities and TD Securities will have “right side” designation and shall appear on the top right of any offering or marketing materials in respect of the Facilities. You further agree that no other titles shall be awarded and no compensation (other than that expressly contemplated by the Debt Financing Letters) shall be paid in connection with the Facilities, unless you and each of us shall reasonably agree.

3. Conditions Precedent. The closing of the Facilities and the making of the initial loans and other extensions of credit under the Facilities on the Closing Date are conditioned solely upon satisfaction or waiver by us of each of the following conditions: (i) since December 31, 2012, there shall not have occurred any Target Material Adverse Effect (as defined below), (ii) since April 30, 2013, there shall not have occurred any Material Adverse Effect (as defined below), (iii) the Specified Purchase Agreement Representations (as defined below) shall be true and correct in all material respects (provided, that any representation and warranty that is qualified as to “materiality,” “material adverse effect” or similar language shall be true and correct in all respects (after giving effect to any such qualification therein)) and (iv) the other conditions expressly set forth in Exhibit B and Exhibit C to this Commitment Letter.

For purposes hereof, the following terms shall have the following meanings:

provided, however, that any such event, change, occurrence, effect or state of facts referred to in clauses (a), (b), (c) or (d) above does not primarily relate only to (or have the effect of primarily relating only to) the Target and its subsidiaries, taken as a whole, or disproportionately adversely affects the Target and its subsidiaries, taken as a whole, compared to other companies of similar size operating in the industries in which the Target and its subsidiaries operate; references in the Arrangement Agreement to dollar amounts are not intended to be and shall not be deemed to be illustrative or interpretative for purposes of determining whether a Target Material Adverse Effect has occurred.

“Material Adverse Effect” means any event, change, occurrence, effect or state of facts, that, individually or in the aggregate with other events, changes, occurrences, effects or states of facts is, or would reasonably be expected to be, material and adverse to the business, operations, results of operations, capital, property, assets, liabilities, obligations (whether absolute, accrued, conditional or otherwise) or financial condition of the Acquiror and its subsidiaries taken as a whole except any such event, change, occurrence, effect or state of facts resulting from or arising in connection with:

(h)

the failure, in and of itself, of the Acquiror to meet any internal or public projections, forecasts or estimates of revenues or earnings (it being understood, without limiting the applicability of paragraphs (a) through (f), that the causes underlying such failure may be taken into account in determining whether a Material Adverse Effect has occurred);

provided, however, that any such event, change, occurrence, effect or state of facts referred to in paragraphs (a), (b), (c) or (d), above does not primarily relate only to (or have the effect of primarily relating only to) the Acquiror and its subsidiaries taken as a whole, or disproportionately adversely affects the Acquiror and its subsidiaries, taken as a whole, compared to other companies of similar size operating in the industries in which the Acquiror and its subsidiaries operate; references in the Arrangement Agreement to dollar amounts are not intended to be and shall not be deemed to be illustrative or interpretative for purposes of determining whether a Material Adverse Effect has occurred.

Notwithstanding anything in the Debt Financing Letters, the Definitive Debt Documents or any other letter agreement or other undertaking concerning the financing of the Transactions to the contrary, (i) the only representations and warranties the accuracy of which shall be a condition to the availability of the Facilities and the making of the initial loans and other extensions of credit on the Closing Date shall be (A) such of the representations and warranties with respect to the Acquired Business in the Arrangement Agreement (as hereinafter defined) as are material to the interests of the Lenders or the Arrangers, but only to the extent that you have (or your applicable affiliate has) the right to terminate your (or its) obligations under the Arrangement Agreement or decline to consummate the Acquisition as a result of a breach of such representations and warranties (as determined without giving effect to any waiver, amendment or other modification thereto, unless such waiver, amendment or other modification has been consented to by the Arrangers) (collectively, the “Specified Purchase Agreement Representations”) and (B) the Specified Representations (as defined below) and (ii) the terms of the Definitive Debt Documents shall be in a form such that they do not impair availability of the Facilities and the making of the initial loans and other extensions of credit on the Closing Date if the conditions expressly set forth in this Section 3 of the Commitment Letter and the other conditions expressly set forth in Exhibit B and Exhibit C to this Commitment Letter are satisfied or waived by us (it being understood that, to the extent any Collateral (other than to the extent that a lien on such Collateral may be perfected (x) by the filing of a financing statement (or local law equivalent) under the Uniform Commercial Code or a Personal Property Security Act, or (y) by the delivery of stock certificates of the Acquiror’s U.S. and Canadian subsidiaries which are required to be delivered under Exhibit A to this Commitment Letter) is not or cannot be perfected on the Closing Date after your use of commercially reasonable efforts to do so, the perfection of a security interest in such Collateral shall not constitute a condition precedent to the availability of the Facilities and the making of the initial loans and other extensions of credit on the Closing Date, but shall be required to be perfected (i) within 30 days after the Closing Date with respect to such Collateral that may be perfected by the filing of a security agreement on the applicable form (or local law equivalent) with the United States Patent and Trademark Office, the United States Copyright Office or the Canadian Intellectual Property Office, and (ii) within 60 days after the Closing Date in respect of such Collateral not described in the immediately preceding clause (i) (in each case subject to extensions granted by the Administrative Agent, in its sole discretion). For purposes hereof, “Specified Representations” means the representations and warranties set forth in the Definitive Debt Documents relating to corporate or other organizational existence, organizational power and authority (as to execution, delivery and performance of the applicable Definitive Debt Documents), the due authorization, execution, delivery and enforceability of the applicable Definitive Debt Documents, solvency of the Acquiror and its subsidiaries on a pro forma consolidated basis on the Closing Date, no conflicts entering into and performance of the Definitive Debt Documents with charter documents or material laws, Federal Reserve margin regulations, the Patriot Act, the Anti-Money Laundering Act, FCPA, OFAC, the Investment Company Act and, subject to permitted liens and the limitations set forth in the prior sentence, the creation, validity, perfection and priority of security interests in the Collateral. This paragraph shall be referred to herein as the “Certain Funds Provision”.

4. Syndication.

(a) The Arrangers reserve the right, at any time after the date hereof and prior to or after execution of the Definitive Debt Documents, to syndicate all or part of their Commitments to banks, financial institutions and other entities identified by Jefferies Finance in consultation with TD Securities and you and, with respect to the Revolving Credit Facility only, subject to your consent (such consent not to be unreasonably withheld, delayed or conditioned) (collectively, with Jefferies Finance and Toronto-Dominion, the “Lenders”). The Commitments of each applicable Commitment Party shall be reduced dollar-for-dollar as and when corresponding commitments are received from any Lenders; provided that, no such reduction shall relieve such Commitment Party of its obligation to fund on the Closing Date the portion of its Commitments so reduced to the extent any Lender fails, upon satisfaction or waiver of all conditions to such Lender making its initial extensions of credit on the Closing Date as set forth or referred to in Section 3 above, to fund its commitment on the Closing Date; provided, further, that unless you agree in writing, we shall retain exclusive control over the rights and obligations with respect to our respective Commitments in respect of the Facilities, including all rights with respect to consents, modifications, supplements and amendments, until the Closing Date has occurred. Jefferies Finance will exclusively manage all aspects of any such syndication in consultation with TD Securities and you, including decisions as to the selection of prospective Lenders to be approached, when they will be approached, when their commitments will be accepted, which prospective Lenders will participate (subject to your rights under the first sentence of this paragraph), the allocation of the commitments and naming rights among the Lenders, and the amount and distribution of fees to Lenders, it being understood and agreed that we will not syndicate to (i) those persons that are competitors (to be defined in the Loan Documents) of you or your subsidiaries or the Target and its subsidiaries or (ii) such other persons in each case, identified in writing to the Arrangers on the date hereof (and in the case of the persons identified in writing to us under clause (ii), any of such person’s affiliates that are identifiable on the basis of such affiliate’s name, by such affiliate’s investment manager’s name or such affiliate’s parent entity’s name) (collectively, the “Disqualified Lenders”). To assist us in the syndication efforts, you agree to furnish, prepare and provide (and to use your commercially reasonable efforts to cause the Acquired Business to prepare and provide) to us all customary information with respect to the Company, the Transactions and the other transactions contemplated hereby, including such Projections (defined below) as any of us may reasonably request in connection with the syndication of the Commitments; provided that, following the consummation of the Acquisition, you shall cause the Acquired Business to prepare and provide us with such information.

(b) We intend to commence syndication efforts promptly upon your execution of this Commitment Letter, and you agree to assist us until the date that is the earlier of (i) 90 days after the Closing Date and (ii) the date on which a Successful Syndication (as defined in the Fee Letter) is achieved but in no event shall such date be earlier than the Closing Date (such earlier date referred to in clause (i) and (ii), the “Syndication Date”). Such assistance shall include:

(iv) your providing to us of copies of any due diligence reports or memoranda prepared at your direction or any of your affiliates by legal, accounting, tax or other third party advisors in connection with the Acquisition, subject to the delivery by us to you and to any such preparers of customary non-disclosure agreements as shall be reasonably requested,

(v) your causing us to receive for distribution to the prospective Lenders, at least five business days prior to the Closing Date a copy of the credit agreement in respect of the Facilities in the form agreed to by the Arrangers and the Borrowers,

Notwithstanding anything to the contrary contained in this Commitment Letter or the Fee Letter, the successful completion of the syndication of the Facilities shall not constitute a condition precedent to the availability and initial funding of the Facilities on the Closing Date.

(c) You agree, at Jefferies Finance’s request, to assist in the preparation of a version of any Materials consisting exclusively of information and documentation that is either (i) publicly available or (ii) not material with respect to the Company, its affiliates or any of its or their respective securities for purposes of Canadian or United States federal, state or provincial securities laws (such information and Materials, “Public Information”). In addition, you agree that, unless specifically labeled “Private – Contains Non-Public Information,” no Materials disseminated to potential Lenders in connection with the syndication of the Facilities, whether through an Internet website, electronically, in presentations, at meetings or otherwise, will contain any Material Non-Public Information (as defined below). Any information and documentation that is not Public Information is referred to herein as “Material Non-Public Information.” It is understood that in connection with your assistance described above, authorization letters will be included in any information package and presentation whereby you authorize the distribution of such information to prospective Lenders, it being understood that the authorization letter for Public Information shall contain a representation by you to the Lenders that the Public Information does not include any such Material Non-Public Information, each letter shall contain a customary “10b-5” representation, and the information package containing solely Public Information will contain customary language exculpating you, the Target and your and their respective affiliates and the Arrangers and their respective affiliates, with respect to any liability related to the use of the contents of such information package or any related marketing materials, by any recipients thereof. You acknowledge and agree that the following documents contain and shall contain solely Public Information (unless you notify us promptly that any such document contains Material Non-Public Information, including by e-mail): (i) drafts and final term sheets and Definitive Debt Documents with respect to the

Facilities, (ii) administrative materials prepared by us for prospective Lenders (including a lender meeting invitation, Lender allocations, if any, and funding and closing memoranda), and (iii) term sheets and notification of changes in the terms of the Facilities. If reasonably requested by us, you shall identify Public Information by clearly and conspicuously marking the same as “PUBLIC”.

(d) You agree that all Materials and Information (as defined below) (including draft and execution versions of the Definitive Debt Documents and draft or final offering materials relating to contemporaneous securities issuances by the Company) may, subject to the limitations in Section 9 of this Commitment Letter, be disseminated for syndication purposes in accordance with our standard syndication practices (including through hard copy and via one or more internet sites (including an IntraLinks, SyndTrak or similar workspace), e-mail or other electronic transmissions). Without limiting the foregoing, you authorize, and will use your commercially reasonable efforts to obtain contractual undertakings from the Acquired Business to authorize, the use of your and its logos in connection with any such dissemination. You further agree that, at its expense, either Arranger may place advertisements in financial and other newspapers and periodicals or on a home page or similar place for dissemination of information on the Internet or worldwide web as such Arranger may choose, and circulate similar promotional materials, after the closing of the Transactions in the form of a “tombstone” or otherwise, containing information customarily included in such advertisements and materials, including (i) the names of the Company and its affiliates (or any of them), (ii) our and our affiliates’ titles and roles in connection with the Transactions, and (iii) the amount, type and closing date of such Transactions.

5. Information. You shall represent and warrant on the Closing Date that (and, with respect to the Target and its subsidiaries, to the best of your knowledge that):

(a) all written information (excluding, for this purpose, all immaterial information, but, in all events, including the Materials) and data other than the Projections (as defined below), forward-looking information and information of a general economic or industry-specific nature (including the Materials, the “Information”) that has been or will be made available to us by or on behalf of you or any of your representatives with respect to the Company is or will be, when furnished, when taken as a whole, complete and correct in all material respects,

(b) none of the Information, when taken as a whole, shall, when furnished or on the Closing Date and when taken as a whole, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not materially misleading, taken as a whole, in light of the circumstances under which such statements are made (after giving effect to all supplements and updates thereto), and

(c) all projections and other forward-looking information that have been or will be made available to any of us by or on behalf of you or the Acquired Business or any of your or its respective representatives (collectively, the “Projections”) have been or will be prepared in good faith based upon (i) accounting principles consistent with the most recent historical audited financial statements of the Acquired Business and (ii) assumptions that are believed by you to be reasonable at the time made (it being understood that any such Projections are not to be viewed as facts, are not a guarantee of financial performance and are subject to uncertainties and contingencies, many of which are beyond your control, that no assurance can be given that any particular Projections will be realized, that actual results may differ and that such differences may be material).

You agree that, if at any time prior to the later of the Closing Date and the Syndication Date, you become aware that any of the representations and warranties in the preceding sentence would be incorrect if the Information or Projections were then being furnished and such representations and warranties were then being made, you shall, at such time, (i) with respect to Information and/or Projections relating to you or your subsidiaries supplement or cause to be supplemented promptly such Information and/or Projections, as the case may be, in order that such representations and warranties will be correct in all

material respects under those circumstances and (ii) with respect to Information and/or Projections relating to the Target or its subsidiaries, use your commercially reasonable efforts to cause the Target to supplement such information in order that such representations and warranties to your knowledge will be correct in all material respects under those circumstances.

You shall be solely responsible for Information, including the contents of all Materials. We (i) will be relying on Information and data provided by or on behalf of you or the Acquired Business or any of your or its representatives or otherwise available from generally recognized public sources, without having independently verified the accuracy or completeness of the same, (ii) do not assume responsibility for the accuracy or completeness of any such Information and data and (iii) will not make an appraisal of your assets or liabilities or the Acquired Business. You shall (i) furnish us with all Information and data that we may reasonably request in connection with our activities on behalf of you and your affiliates and the Acquired Business and (ii) provide us full access, as reasonably requested, to your respective officers, directors, employees and professional advisors and use commercially reasonable efforts to provide us full access, as reasonably requested, to those of the Acquired Business; provided that, following the consummation of the Acquisition, you shall cause the Acquired Business to provide us full access, as reasonably requested, to such persons or entities.

6. Clear Market. You agree that, from the date hereof until the Syndication Date, you will not, and you will use commercially reasonable efforts not to permit the Acquired Business to, directly or indirectly, (i) syndicate, place, sell or issue, (ii) attempt or offer to syndicate, place, sell or issue, (iii) announce or authorize the announcement of the syndication, placement, sale or issuance of, or (iv) engage in discussions concerning the syndication, placement, offering, sale or issuance of, any debt facility, or debt security of you, the Acquired Business or any of your or its respective affiliates (other than the Debt Financing contemplated hereby), including any renewals or refinancings of any existing debt facility, without each Arranger’s prior written consent. Notwithstanding anything in this Commitment Letter to the contrary, the provisions of this Section 6 shall not apply in the event of a material breach by any Commitment Party of its funding obligations under this Commitment Letter.

7. Fees and Expenses. As consideration for the Commitments and our other undertakings hereunder, you hereby agree to pay or cause to be paid to us the fees, expenses and other amounts set forth in the Debt Financing Letters.

8. Indemnification and Waivers. You agree to indemnify and hold harmless each of us, the Lenders and each of our and their respective affiliates (including, without limitation, controlling persons) and each director, officer, employee, advisor, agent, affiliate, successor, partner, representative and assign of each of the foregoing (each an “Indemnified Person”) from and against any and all actions, suits, investigation, inquiry, claims, actual losses, damages, liabilities or proceedings of any kind or nature whatsoever (each a “Claim”) which may be incurred by or asserted against or involve any such Indemnified Person as a result of or arising out of or in any way related to or resulting from the Debt Financing Letters, the Facilities, the use of proceeds thereof, the Transactions or the other transactions contemplated hereby or thereby (regardless of whether any such Indemnified Person is a party thereto and regardless of whether such matter is initiated by a third party or otherwise) (any of the foregoing, a “Proceeding”), and you agree to reimburse each Indemnified Person within ten days following demand for any reasonable and documented (pursuant to a summary statement thereof) legal or other out-of-pocket expenses incurred in connection with investigating, defending, preparing to defend or participating in any such Proceeding; provided, however, that no Indemnified Person will be indemnified for any such cost, expense or liability to the extent determined by a final non-appealable judgment of a court of competent jurisdiction to have resulted from (i) the gross negligence, willful misconduct or bad faith of such Indemnified Person, (ii) a material breach by an Indemnified Person of its obligations under this Commitment Letter or the Fee Letter at a time when you have not breached your obligations hereunder in any material respect, or (iii) a dispute among Indemnified Parties not arising from any breach by you of your obligations hereunder in any material respect (other than a claim against any Commitment Party

solely in its capacity as an Arranger or Agent). In the case of any Proceeding to which the indemnity in this paragraph applies, such indemnity and reimbursement obligations shall be effective, whether or not such Proceeding is brought by you, the Target, any of your or their respective securityholders or creditors, an Indemnified Person or any other person, or an Indemnified Person is otherwise a party thereto and whether or not any aspect of the Debt Financing Letters, the Facilities or any of the Transactions are consummated.

You shall not settle or compromise or consent to the entry of any judgment in or otherwise seek to terminate any pending or threatened Claim in which any indemnified person is or could be a party and as to which indemnification or contribution could have been sought by such Indemnified Person hereunder whether or not such indemnified person is a party to any Debt Financing Letter, unless (i) such indemnified person and each other Indemnified Person from which such Indemnified Person could have sought indemnification or contribution have given their prior written consent, which may be given or withheld in their sole discretion or (ii) the settlement, compromise, consent or termination (A) includes an express unconditional release of all indemnified persons and their respective affiliates from all losses, claims, damages and liabilities, directly or indirectly, arising out of, relating to, resulting from or otherwise in connection with such Claim and (B) does not include any statement as to or any admission of fault, culpability, wrongdoing or a failure to act by or on behalf of any Indemnified Person.

Our obligations under this paragraph shall automatically terminate and be superseded by the confidentiality provisions in the Definitive Debt Documents upon the execution and delivery thereof and in any event shall terminate on the first anniversary of the date hereof.

With respect to any securities and/or financial instruments so held by any Commitment Party, any of its affiliates or any of its respective customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the holder of such rights, in its sole discretion.

SUMMARY OF TERMS OF $405.0 MILLION FACILITIES

Set forth below is a summary of the principal terms of the Term Loan Facility and Revolving Credit Facility and the documentation related thereto. Capitalized terms used and not otherwise defined in this Exhibit A have the meanings set forth elsewhere in this Commitment Letter.



I.	Parties

	Borrowers	Mitel Networks Corporation (“*Mitel”), in its capacity as a borrower under the below-defined Revolving Credit Facility, and Mitel US Holdings, Inc. (“MUSHI”), in its capacity as a borrower under the below-defined Term Loan Facility and under the Revolving Credit Facility (each a “Borrower” and collectively, the “Borrowers*”).

	Guarantors	Each Borrower and each of Mitel’s existing or subsequently acquired direct and indirect wholly-owned subsidiaries (other than (a) immaterial subsidiaries (to be defined in a mutually acceptable manner as to individual and aggregate revenues or assets excluded consistent with the Documentation Principles), (b) any subsidiary that is prohibited by applicable law, rule or regulation existing on the Closing Date or by applicable law, rule or regulation or by any contractual obligation existing at the time of acquisition thereof after the Closing Date (to the extent such contractual obligation was not created in contemplation of such acquisition) for so long as such prohibition exists, in each case from guaranteeing the Facilities, or (c) any subsidiary to the extent such subsidiary providing a guarantee may result in an adverse tax consequence to the Borrowers or any of their subsidiaries (including as a result of the operation of Section 956 of the U.S. Internal Revenue Code (the “*Code”) or any similar law or regulation in any applicable jurisdiction) as reasonably determined by the Borrowers) (collectively, the “Guarantors;” the Borrowers and the Guarantors, collectively, the “Credit Parties*”).

	Joint Lead Arrangers and Joint Bookrunners	Jefferies Finance LLC (“*Jefferies Finance”) and TD Securities (USA) LLC (“TD Securities”) and/or one or more of their respective designees approved by the Borrowers (in such capacities, each an “Arranger” and, together, the “Arrangers*”). The Arrangers will perform the duties customarily associated with such role.

	Administrative Agent	Jefferies Finance and/or one or more of its designees approved by the Borrowers (in such capacity, the “*Administrative Agent*”). The Administrative Agent will perform the duties customarily associated with such role.

Exhibit A-1


	Collateral Agent	Jefferies Finance and/or one or more of its designees approved by the Borrowers (in such capacity, the “*Collateral Agent*”). The Collateral Agent will perform the duties customarily associated with such role.

	Lenders	A syndicate of banks, financial institutions and other entities (including Jefferies Finance and Toronto-Dominion) (collectively, the “*Lenders*”) identified by the Arrangers in consultation with the Borrowers and, with respect to the Revolving Credit Facility only, subject to the Borrowers’ consent (such consent not to be unreasonably withheld, delayed or conditioned); it being understood and agreed that the Arrangers will not syndicate to Disqualified Lenders.

	Closing Date	The date, on or before the date on which the Commitments are terminated in accordance with Section 15 of the Commitment Letter, on which the Acquisition is consummated and the initial funding of the Facilities has occurred (the “*Closing Date*”).

	Loan Documents	The definitive documentation governing or evidencing the Facilities (collectively, the “*Loan Documents*”).

II.	Types and Amounts of Facilities

	Term Loan Facility	A senior secured first lien term loan facility in an aggregate principal amount equal to $355.0 million (the “*Term Loan Facility”) (the loans thereunder, the “Term Loans*”).

		The full amount of the Term Loan Facility (other than any Incremental Term Loans) shall be drawn by MUSHI in a single drawing on the Closing Date. Amounts borrowed under the Term Loan Facility that are repaid or prepaid may not be reborrowed.

	Final Maturity and Amortization of Term Loan Facility	The Term Loan Facility will mature on the date that is 6 years after the Closing Date and will amortize at an annual rate of 1.0% in equal quarterly installments of 0.25% of the original principal amount of the Term Loan Facility, with the balance payable on the sixth anniversary of the Closing Date. The first installment shall be due and payable on the last day of the first full fiscal quarter following the Closing Date. Notwithstanding any of the foregoing, the Loan Documents shall provide the right for individual Lenders under the Term Loan Facility to agree to extend the maturity date of the outstanding Term Loans upon the request of the Borrowers and without the consent of any

Exhibit A-2


				other Lender pursuant to customary procedures to be agreed (any such loans that have been so extended, the “*Extended Term Loans”); it being understood that each Lender under the applicable tranche or tranches that are being extended shall have the opportunity to participate in such extension on the same terms and conditions as each other Lender in such tranche or tranches; provided, that it is understood that no existing Lender will have any obligation to commit to any such extension. The terms of the Extended Term Loans shall be substantially similar to the Term Loans except for interest rates, fees, amortization (so long as, prior to the final stated maturity of the Term Loans, the amortization of such Extended Term Loans does not exceed equal quarterly installments in an aggregate annual amount equal to 1% of the original principal amount of the Extended Term Loans), final maturity date, provisions requiring optional and mandatory prepayments to be directed first to the non-extended Term Loans prior to being applied to Extended Term Loans and certain other provisions to be agreed, provided* that the Extended Term Loans shall not benefit from Guarantees or Collateral that do not also benefit the existing Term Loans, and further provided that other terms of the Extended Term Loans may differ from the Term Loans to the extent such differences do not apply until after the final stated maturity of the Term Loans. The Administrative Agent and Borrowers shall be permitted to effect such amendments to the Loan Documents as may be necessary or appropriate to give effect to the foregoing, including conforming amendments (which may be in the form of an amendment and restatement), without the consent of each Lender, other than the Lenders agreeing to extend such Extended Term Loans.

		Incremental Credit Facilities		The Borrowers shall have the right to increase the size of the Term Loan Facility and/or the Revolving Credit Facility (x) with respect to the Term Loan Facility, “*Incremental Term Loan Commitments” and such new loans, “Incremental Term Loans” and (y) respect to the Revolving Credit Facility, “Incremental Revolving Commitments” and such new loans, “Incremental Revolving Credit Loans”; each of the Incremental Term Loans and Incremental Revolving Credit Commitments may hereinafter be referred to as the “Incremental Facility*”), at any time after the Closing Date from willing Lenders and/or eligible assignees up to an aggregate total principal amount not to exceed $75.0 million in the aggregate, subject to the following: (i) not more than two increases in the size of the Term Loan Facility and/or the Revolving Credit Facility shall occur,

Exhibit A-3

(ii) no default or event of default has occurred and is continuing, or would immediately occur after giving effect to, such Incremental Term Loan Commitments, Incremental Revolving Commitments and the proposed Incremental Term Loans and Incremental Revolving Credit Loans, as applicable,

(iii) the Borrowers shall have certified to the Administrative Agent that the full amount of the respective Incremental Term Loans or Incremental Revolving Credit Loans may be incurred without violating the terms of the Facilities,

(iv) the Incremental Term Loans shall have a maturity no earlier than the Term Loan Facility and shall have a weighted average life to maturity no shorter than the Term Loan Facility,

(v) the initial yield (to be defined to include all applicable margin, interest rate floors, upfront fees, original issue discount or similar yield-related discounts, deductions or payments, but excluding any customary arrangement or similar fees in connection therewith that are not paid to all of the Lenders providing the Incremental Term Loans or the Incremental Revolving Credit Loans, as applicable) of the Incremental Term Loans or the Incremental Revolving Credit Loans, as applicable, shall be no greater than 0.50% per annum higher than the corresponding all-in yield applicable to the existing Term Loan Facility or the Revolving Credit Facility, as applicable (or, if such initial yield on the Incremental Term Loans or Incremental Revolving Credit Loans, as applicable, exceeds the all-in yield on the existing Term Loan Facility or the Revolving Credit Facility, as applicable, then the interest rate margin for the existing Term Loan Facility or the Revolving Credit Facility, as applicable, shall automatically be increased to equal such initial yield on the Incremental Term Loans or the Incremental Revolving Credit Loans, as applicable, less 0.50%),

(vi) the Borrowers shall be in pro forma compliance with (x) the financial maintenance covenant and (y) a ratio equal to the Closing Date Net Leverage Ratio (as defined below), in each case, on the date of incurrence and for the most recently-ended determination period after giving effect to such Incremental Term Loan Commitments and the proposed Incremental Term Loans and other customary and appropriate adjustment events,

Exhibit A-4

including certain acquisitions or dispositions after the beginning of the relevant determination period but prior to or simultaneous with the borrowing of such Incremental Term Loans (assuming, for purposes of pro forma compliance under preceding clause (x) with the maximum consolidated total net leverage ratio, that the maximum consolidated total net leverage ratio permitted at such time was 0.25 to 1.00 below the ratio actually required to be maintained at such time),

(vii) the representations and warranties shall be true and correct in all material respects (without duplication of any materiality qualifiers set forth therein) immediately prior to, and immediately after giving effect to, the incurrence of such Incremental Term Loans or Incremental Revolving Commitments or Incremental Revolving Credit Loans (although any representations and warranties which expressly relate to a given date or period shall be required to be true and correct in all material respects (without duplication of any materiality qualifiers set forth therein) as of the respective date or for the respective period, as the case may be),

(viii) the terms of the Incremental Term Loan Commitments shall be otherwise reasonably satisfactory in all respects to the Administrative Agent to the extent that such terms, except to the extent set forth above, are not consistent with the Term Loan Facility, and

(ix) any Incremental Revolving Commitment will be documented solely as an increase to the commitments with respect to the Revolving Credit Facility, without any change in terms except as set forth above.

None of the existing Lenders under the Facilities will be required to provide any Incremental Term Loan Commitments or Incremental Revolving Commitments, and any decision whether or not to do so by any such Lender shall be made at the sole discretion of such Lender.

For purposes of this Commitment Letter, unless the context otherwise requires, Incremental Term Loans shall constitute “Term Loans” and shall be subject to the provisions of this Commitment Letter (including mandatory prepayment requirements) to the same extent as Term Loans.

“Closing Date Net Leverage Ratio” shall mean the ratio on the Closing Date of (i) indebtedness of any of the Borrowers and their subsidiaries on a consolidated basis, net of unrestricted cash and cash equivalents of the

Exhibit A-5


				Credit Parties in an aggregate amount not to exceed $50.0 million, to (ii) Consolidated EBITDA (to be defined in a manner consistent with the Documentation Principles) of the Borrowers and their subsidiaries for the most recently ended four-fiscal quarter period for which financial statements have been delivered.

		Revolving Credit Facility		A senior secured first lien revolving credit facility (the “*Revolving Credit Facility” and, together with the Term Loan Facility, the “Facilities”) in an aggregate principal amount equal to $50.0 million, the “Revolving Credit Loans” and, together with the Term Loans, the “Loans*”). Amounts repaid under the Revolving Credit Facility may be reborrowed. Borrowings, Letters of Credit, Swing Line Loans and banker’s acceptances under the Revolving Credit Facility will be available to Mitel in Canadian Dollars. Borrowings, Letters of Credit and Swing Line Loans under the Revolving Credit Facility will be available to MUSHI in U.S. Dollars.

		Maturity of Revolving Credit Facility		The Revolving Credit Facility shall be available to either Borrower on a revolving basis during the period commencing on the Closing Date (subject to the limitations set forth under the caption “Use of Proceeds” set forth below) and ending on the fifth anniversary of the Closing Date (the “*Revolving Credit Termination Date*”).

		Letters of Credit		A portion of the Revolving Credit Facility not in excess of an amount to be mutually agreed shall be available for the issuance of standby letters of credit (the “*Letters of Credit”) by one or more Lenders or affiliates of Lenders to be determined (each such Lender in such capacity, an “Issuing Lender”), which Letters of Credit shall be risk participated to all Lenders with commitments under the Revolving Credit Facility, to support obligations of the Borrowers and their wholly owned subsidiaries reasonably satisfactory to the Issuing Lender. The face amount of any outstanding Letters of Credit will reduce availability under the Revolving Credit Facility on a dollar-for-dollar basis. No Letter of Credit shall have an expiration date after the earlier of (i) one year after the date of issuance and (ii) five business days prior to the Revolving Credit Termination Date; provided* that any Letter of Credit with a one-year tenor may provide for the automatic renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above).

Exhibit A-6



				Drawings under any Letter of Credit shall be reimbursed by the Borrowers (whether with any Borrower’s own funds or with the proceeds of Revolving Credit Loans) on the immediately succeeding business day. To the extent that the Borrowers do not so reimburse the Issuing Lender, the Lenders under the Revolving Credit Facility shall be irrevocably and unconditionally obligated to reimburse the Issuing Lender on a pro rata basis based on their respective Revolving Credit Facility commitments. A portion of the Revolving Credit Facility not in excess of an amount, and on terms and conditions, to be mutually agreed shall be available for Canadian banker’s acceptances.

		Swing Line Loans		A portion of the Revolving Credit Facility not in excess of an amount to be mutually agreed shall be available on same-day notice for swing line loans (the “*Swing Line Loans”) from a Lender to be selected by the Administrative Agent in consultation with the Borrowers (in such capacity, the “Swing Line Lender”). Any such Swing Line Loans will reduce availability under the Revolving Credit Facility on a dollar-for-dollar basis. Each Lender under the Revolving Credit Facility shall acquire, under certain circumstances, an irrevocable and unconditional pro rata* participation in each Swing Line Loan.

		Currency Matters		Loan fundings and payments in respect of non-U.S. dollar loans will be made in Canadian Dollars. All unreimbursed Letter of Credit draws to be funded by the Lenders will be immediately due and payable in the same currency in which such draws were made. In the case of loans, Letters of Credit and banker’s acceptances denominated in Canadian Dollars, the Administrative Agent will at periodic intervals, and may, at its discretion, at other times, recalculate the aggregate exposure under such loans, Letters of Credit and banker’s acceptances denominated in Canadian Dollars and outstanding under the Revolving Credit Facility at any time to account for fluctuations in exchange rates affecting the Canadian Dollar. All calculations by the Administrative Agent of foreign currency equivalents will be based on its spot foreign exchange rates. If, as a result of any such recalculation, the aggregate exposure in respect of obligations outstanding under the Revolving Credit Facility exceeds an amount equal to 102% of aggregate Revolving Credit Facility commitments, the Borrowers will prepay loans and other obligations and, if applicable, cash collateralize Letters of Credit in the amount necessary to eliminate such excess.

Exhibit A-7



	Use of Proceeds	The proceeds of the Term Loans borrowed on the Closing Date will be used directly or indirectly to finance, in part, purchase of the Shares pursuant to the Arrangement, the Refinancing and the cash-out of outstanding stock appreciation rights and deferred share units issued by the Target, and to pay fees and expenses in connection with the foregoing. The proceeds of the Revolving Credit Loans will be used (i) on the Closing Date up to an amount to be mutually agreed to finance, in part, the Acquisition and to pay upfront fees (or original issue discount) and expenses in connection with the Facilities (ii) after the Closing Date for the working capital and general corporate purposes of the Borrowers and their subsidiaries (including permitted acquisitions, capital expenditures and permitted distributions). The proceeds of any Incremental Facility will be used by the Borrowers for general corporate purposes of Borrowers and their subsidiaries (including, without limitation, permitted acquisitions, capital expenditures and permitted distributions). Letters of Credit will be used to support payment and performance obligations incurred in the ordinary course of business by the Borrowers and their subsidiaries.

III.	Certain Payment Provisions

	Fees and Interest Rates	As set forth on Annex A-I hereto.

	Optional Prepayments and Commitment Reductions	Optional prepayments of borrowings under the Facilities and optional reductions of the unutilized portion of the commitments under the Facilities will be permitted at any time, in minimum principal amounts to be agreed upon, without premium or penalty (subject to (i) reimbursement of the Lenders’ redeployment costs in the case of a prepayment of Adjusted LIBOR Loans other than on the last day of the relevant interest period and (ii) payments of an amount provided below under the caption “Call Protection on Term Loans”). Voluntary prepayments of the Term Loan Facility shall be applied to remaining scheduled amortization payments as directed by the Borrowers.

Exhibit A-8



Mandatory Prepayments and Commitment Reductions	The following amounts will be applied to prepay the Term Loans or, if all Term Loans have then been repaid, to prepay Revolving Credit Loans (or, if none, to cash collateralize Letters of Credit thereunder), without a reduction of the commitments thereunder, in each case consistent with the Documentation Principles:

	•	100% of the net cash proceeds of any incurrence of indebtedness after the Closing Date (other than indebtedness permitted under the Loan Documents and excluding for certainty any Incremental Facilities) by any Borrower or any of their subsidiaries (with additional exceptions to be agreed upon); and

	•	100% of the net cash proceeds in excess of a threshold to be mutually and reasonably agreed of any non-ordinary course sale or other disposition of assets by any Borrower or any of their subsidiaries (excluding sales of inventory in the ordinary course and including (i) as a result of casualty or condemnation and (ii) any sale of the equity interests in any Credit Party (other than Mitel) or subsidiary of a Credit Party to a non-credit party) (subject to customary exceptions and reinvestment rights, and such other exceptions consistent with the Documentation Principles); and

	•	50% of “excess cash flow” (to be defined in a manner consistent with the Documentation Principles, and in any event, giving dollar-for-dollar credit for voluntary prepayments to the Term Loan Facility and the Revolving Credit Facility, to the extent such prepayments of the Revolving Credit Facility are accompanied by a permanent and concurrent commitment reduction thereunder) for each fiscal year of the Borrowers (commencing with the fiscal year ending December 31, 2014), with step-downs to be agreed upon based on compliance with a consolidated total net leverage ratio to be agreed.

	All such mandatory prepayments shall be applied without premium or penalty (except for customary breakage costs, if any) and shall be applied in the following order: first, to the next four scheduled unpaid installments of principal of the Term Loan Facility in direct order of maturity and thereafter pro rata to the remaining scheduled installments of principal of the Term Loan Facility and second, to the Revolving Credit Facility (including to cash collateralize Letters of Credit) (without a reduction of the commitments thereunder).

Exhibit A-9



		The Revolving Credit Loans will be prepaid and the Letters of Credit will be cash collateralized to the extent such extensions of credit at any time exceed an amount equal to 102% of aggregate commitments in respect of the Revolving Credit Facility.

	Call Protection on Term Loans	The Borrowers shall pay a “prepayment premium” in connection with any Repricing Event (as defined below) with respect to all or any portion of the Term Loans that occurs on or before the date occurring six months after the Closing Date (the “*Soft Call Date”), in an amount not to exceed 1.0% of the principal amount of the Term Loans subject to such Repricing Event. The term “Repricing Event*” shall mean (i) any prepayment or repayment of Term Loans with the proceeds of, or any conversion of Term Loans into, any new or replacement tranche of term loans bearing interest at an “effective” interest rate less than the “effective” interest rate applicable to the Term Loans (as such comparative rates are determined by the Administrative Agent in consultation with the Borrowers), and (ii) any amendment to the Term Loan Facility that, directly or indirectly, reduces the “effective” interest rate applicable to the Term Loans (in each case, with original issue discount and upfront fees, which shall be deemed to constitute like amounts of original issue discount, being equated to interest margins in a manner consistent with generally accepted financial practice based on an assumed four-year life to maturity), including any mandatory assignment in connection therewith with respect to each Lender that refuses to consent to such amendment. Notwithstanding anything in this paragraph to the contrary, in no event will any prepayment premium be payable pursuant to this paragraph in connection with the occurrence of a Change of Control (to be defined). After the Soft Call Date, the Facilities may be prepaid in whole or in part at any time without premium or penalty (other than customary breakage costs).

IV.	Collateral and Guarantees

	Collateral	Subject to the limitations set forth below in this section, subject to the Certain Funds Provision, and subject to the Documentation Principles, the obligations of each Credit Party in respect of the Facilities, any interest rate hedging obligations of the Borrowers owed to a Lender, the Administrative Agent, an Arranger or their respective affiliates or to an entity that was a Lender, the

Notwithstanding anything to the contrary, the Collateral shall exclude the following: (i) any fee-owned real property with a value of less than an amount to be agreed and any leasehold interests; (ii) motor vehicles and other assets subject to certificates of title, letter of credit rights (except to the extent perfection can be obtained by filing of financing statements) and commercial tort claims with a value of less than an amount to be agreed; (iii) any lease, license or other similar agreement or any property subject to a purchase money security interest or similar arrangement to the extent that a grant of a security interest therein would violate or invalidate such lease, license or similar agreement or purchase money arrangement or create a right of termination in favor of any other party thereto (other than a Borrower or a Guarantor) after giving effect to the applicable anti-assignment provisions of applicable law, other than proceeds and receivables thereof, the assignment of which is expressly deemed effective under applicable

Exhibit A-11


		law notwithstanding such prohibition; (iv) any intent to use trademark applications; (v) letter of credit rights and commercial tort claims with a value below an amount to be agreed; (vi) any governmental licenses or state or local franchises, charters and authorizations, to the extent security interests in such licenses, franchises, charters or authorizations are prohibited or restricted thereby; (vii) any assets of any “controlled foreign corporation” within the meaning of Section 957 of the Code to the extent it would result in adverse tax consequences; (viii) purchased leases (that have not been repurchased) and collateral relating to such purchased leases; and (ix) subject to, and consistent with, the Documentation Principles, any other assets that are excluded under the terms of the security in place in respect of the Existing Credit Agreement (the foregoing described in clauses (i) through (ix) are collectively, the “*Excluded Assets*”). All the above-described pledges, security interests and mortgages shall be created on terms to be set forth in the Loan Documents; and none of the Collateral shall be subject to other pledges, security interests or mortgages (subject to customary exceptions for financings of this kind to be agreed).

	Guarantees	The Guarantors will unconditionally, and jointly and severally, guarantee the obligations of each Credit Party in respect of the Facilities and, to the extent requested by the Arrangers, the Permitted Secured Hedging Obligations and the Permitted Cash Management Obligations (the “*Guarantees*”). Such Guarantees will be in form consistent with the Documentation Principles. All Guarantees shall be guarantees of payment and performance, and not of collection. Notwithstanding anything contained herein to the contrary, no Credit Party shall be jointly and severally liable or guarantee any Permitted Secured Hedging Obligations if, and to the extent that such liability or such guaranty of such swap obligation is or becomes illegal under the Commodity Exchange Act (determined after giving effect to any keepwell or other support for the benefit of such Credit Party).

V.	Other Provisions
