Lynch) and each of the other Underwriters named in Schedule A hereto (collectively, the Underwriters, which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom
Merrill Lynch, J.P. Morgan Securities Inc. and UBS Securities LLC are acting as representatives (in such capacity, the Representatives), with respect to (i) the sale by the Company and the purchase by the Underwriters,
acting severally and not jointly, of the respective numbers of common shares of the Company (Common Shares) set forth in Schedules A and B hereto and (ii) the grant by the Selling Shareholders to the Underwriters, acting
severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 1,578,947 additional Common Shares to cover overallotments, if any. The aforesaid 10,526,316 Common Shares (the Initial
Securities) to be purchased by the Underwriters and all or any part of the 1,578,947 Common Shares subject to the option described in Section 2(b) hereof (the Option Securities) are herein called, collectively, the
Securities.

The Company and the Selling Shareholders understand that the Underwriters propose to make a
public offering of the Securities in the United States, and each of the provinces and territories of Canada (the Qualifying Jurisdictions), either directly or through their respective U.S. or Canadian broker-dealer affiliates, as
soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company, the Selling Shareholders and the Underwriters agree that up to 500,000 Initial
Securities to be purchased by the Underwriters (the Reserved Securities) shall be reserved for sale to certain persons designated by the Company (the Invitees), as part of the distribution of the Securities by
the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority, Inc. (FINRA) and all other applicable laws, rules and regulations. The
Company solely determined, without any direct or indirect participation by the Underwriters, the Invitees who will purchase Reserved Securities (including the amount to be purchased by such persons) sold by the Underwriters. To the extent that such
Reserved Securities are not orally confirmed for purchase by Invitees by 8:00 A.M. (New York City time) on the first business day after the date of this Agreement, such Reserved Securities may be offered to the public as part of the public offering
contemplated hereby.

The Company has filed with the United States Securities and Exchange Commission (the
Commission) a registration statement on Form F-1 (No. 333-163930), including the related preliminary prospectus or prospectuses, covering the registration of the sale of the Securities under the Securities Act of 1933, as
amended (the 1933 Act). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (Rule 430A) of the rules and
regulations of the Commission under the 1933 Act (the 1933 Act Regulations) and Rule 424(b) (Rule 424(b)) of the 1933 Act Regulations. The information included in such prospectus that was omitted from such
registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to Rule 430A(b) is herein called the Rule 430A Information. Such
registration statement, including the amendments thereto, the exhibits thereto and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the Registration Statement. Any
registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein called the Rule 462(b) Registration Statement and, after such filing, the term Registration Statement shall include the Rule
462(b) Registration Statement. Each prospectus used in the United States prior to the effectiveness of the Registration Statement, and each prospectus used in the United States that omitted the Rule 430A Information that was used after such
effectiveness and prior to the execution and delivery of this Agreement, is herein called a U.S. Preliminary Prospectus. The final U.S. prospectus, in the form first furnished to the Underwriters for use in connection with the
offering of the Securities, is herein called the U.S. Prospectus. For purposes of this Agreement, all references to the Registration Statement, any U.S. Preliminary Prospectus, the U.S. Prospectus or any amendment or supplement to
any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (EDGAR).

The Company has also prepared and filed with the Ontario Securities Commission (the Principal Regulator) and with the
securities regulatory authorities in each of the other Qualifying Jurisdictions (together with the Principal Regulator, the Qualifying Authorities) one or more preliminary PREP prospectuses relating to the Securities (in the
English and French languages, as applicable, each a Preliminary PREP Prospectus) pursuant to the passport system procedures provided for under Mulitlateral Instrument 11-102Passport System and National Policy 11-202
 Process for Prospectus Reviews in Multiple Jurisdictions(together, the Passport System) and National Instrument 44-103  Post-Receipt Pricing (collectively with the Passport System, the PREP
Procedures). The Principal Regulator has issued a preliminary Passport System decision document for each Preliminary PREP Prospectus.

In addition, the Company (A) has prepared and filed with the Qualifying Authorities a final PREP prospectus relating to the
Securities (in the English and French languages, as applicable, the Final PREP Prospectus) which omits the PREP Information (as hereinafter defined) in accordance with the PREP Procedures, and (B) will, promptly after the
execution and delivery of this Agreement, prepare and file with the Qualifying Authorities, in accordance with the PREP Procedures, a supplemented PREP prospectus setting forth the PREP Information (in the English and French languages, as
applicable, the Supplemented PREP Prospectus). The Principal Regulator has issued a final decision document for the Final PREP Prospectus in accordance with the Passport System. The information included in the Supplemented PREP
Prospectus that is omitted from the Final PREP Prospectus and which is deemed under the PREP Procedures to be incorporated by reference in the Final PREP Prospectus as of the date of the Supplemented PREP Prospectus is referred to herein as the
PREP Information.

Each Preliminary PREP Prospectus is herein called a Canadian Preliminary
Prospectus. The Final PREP Prospectus for which a final Passport System decision document has been received from the Principal Regulator on behalf of itself and the other Qualifying Authorities, including the PREP Information incorporated
by reference therein, is herein referred to as the Canadian Prospectus, except that, if, after the execution of this Agreement, a Supplemented PREP Prospectus containing the PREP Information is filed with the Qualifying
Authorities, the term Canadian Prospectus shall refer to such Supplemented PREP Prospectus. As used herein, Canadian Securities Laws means, collectively, the applicable securities laws of each of the Qualifying
Jurisdictions and the respective regulations and rules made under those securities laws together with all applicable policy statements, blanket orders and rulings of the Qualifying Authorities. For purposes of this Agreement, all references to any

Governmental Licenses would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. The Company and its subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where
the failure so to comply would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental
Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received
any notice of proceedings relating to the revocation or modification of any Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material

been or will be promptly taken and as to which adequate reserves have been provided. The United States, UK and Canadian federal income tax returns of the Company through, in each case, the most recent fiscal year end for which such tax returns are
due to be filed have been settled and no assessment in connection therewith has been made against the Company. The Company and its subsidiaries have filed all other tax returns that are required to have been filed by them pursuant to applicable

of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would
not result in a Material Adverse Effect. The statements set forth in the General Disclosure Package and the Prospectuses under the caption Material United States Federal Income Tax Considerations and Material Canadian Federal
Income Tax Considerations for U.S. Holders, insofar as they purport to describe the tax consequences to holders of the ownership and disposition of the Securities or legal conclusions with respect thereto, and subject to the limitations,

the laws of any state, province or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Company or sale by the Company of the Securities. No stamp duty,
registration or documentary taxes, duties or similar charges are payable under the federal laws of Canada or the laws of any province in connection with the issuance, sale and delivery to the Underwriters of the Securities or the authorization,

limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or

or the CFPOA and the Company and, to the knowledge of the Company, its affiliates have conducted their businesses in compliance with the FCPA and the CFPOA and have instituted and maintain policies and procedures designed to ensure, and which are
reasonably expected to continue to ensure, continued compliance therewith.

(b) Option Securities. In

local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e)
Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel and is entitled to such reimbursement
pursuant to the terms of this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) or settlement of any claim in connection with any violation referred to in
Section 6(f) effected without its written consent (subject to the limitations contained herein) if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with
such request prior to the date of such settlement.

(f) Indemnification for Reserved Securities. In connection with the offer and sale of
the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters, their Affiliates and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of
the 1934 Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim),
as incurred, (i) arising out of the violation of any applicable laws or regulations of foreign jurisdictions where Reserved Securities have been offered, (ii) arising out of any untrue statement or alleged untrue statement of a material
fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offering of the Reserved Securities or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed
for purchase by any Invitee by 8:00 A.M. (New York City time) on the first business day after the date of the Agreement or (iv) related to, or arising out of or in connection with, the offering of the Reserved Securities.

(g) Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any agreement among the
Company and the Selling Shareholders with respect to indemnification.

SECTION 7. Contribution. If the indemnification
provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and
the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Shareholders, on the one hand, and of the Underwriters, on the other hand, in
connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(f) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable
considerations.

The relative benefits received by the Company and the Selling Shareholders, on the one hand, and the
Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this
Agreement (before deducting expenses) received by the Company and the Selling Shareholders, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover
of the U.S. Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the U.S. Prospectus.

The relative fault of the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, shall be
determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling
Shareholders or by the Underwriters and the parties relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 6(f) hereof.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred
to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this
Section 7, (i) no Selling Shareholder shall be required to contribute in the aggregate under this Agreement any amount in excess of the Selling Shareholder Amount received by such Selling Shareholder from the sale of Securities sold by
such Selling Shareholder hereunder, and (ii) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriters Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each
officer of the Company who signed the Registration Statement, any Canadian Preliminary Prospectus or the Canadian Prospectus, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be. The Underwriters respective obligations to contribute pursuant to this Section 7 are
several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint. The Selling Shareholders respective obligations to contribute pursuant to this Section 7 are several
in proportion to the number of Securities set forth opposite their respective names in Schedule B hereto and not joint.

The
provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

SECTION 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on
behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors, any person controlling the Company or any person controlling any Selling Shareholder and (ii) delivery of and
payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination. The Representatives may terminate this Agreement, by notice to the Company and the Selling Shareholders, at any
time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectuses, any material adverse
change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if
there has occurred any material adverse change in the financial markets in the United States or Canada or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development
involving a prospective change in the United States, Canadian or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable
to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission, any Qualifying Authority or other securities
commission or regulatory authority in Canada or the Nasdaq Global Market, or (iv) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for
trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, any Qualifying Authority or other securities commission or regulatory authority in Canada, FINRA or any other
governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or Canada or with respect to Clearstream or Euroclear systems in Europe, or (vi) if
a banking moratorium has been declared by either United States federal, New York state or Canadian authorities.

(b)
Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 15
and 16 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the
Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the Defaulted Securities), the
Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such
amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date,
each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting Underwriters, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of
Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Securities to be purchased and
sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.



23



---

No action taken pursuant to this Section shall relieve any defaulting Underwriter from
liability in respect of its default. The foregoing sentence shall survive any termination of this Agreement.

In the event of
any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company
to sell the relevant Option Securities, as the case may be, either (i) the Representatives or (ii) the Company and any Selling Shareholder shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be,
for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectuses or in any other documents or arrangements. As used throughout this Agreement, the term
Underwriter includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Default
by one or more of the Selling Shareholders or the Company. (a) If a Selling Shareholder shall fail at the Closing Time or a Date of Delivery, as the case may be, to sell and deliver the number of Securities which such Selling Shareholder or
Selling Shareholders are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number to be
sold by all Selling Shareholders as set forth in Schedule B hereto, then the Underwriters may, at the option of the Representatives, by written notice from the Representatives to the Company and the non-defaulting Selling Shareholders, either
(i) terminate this Agreement without any liability on the part of any non-defaulting party except that the provisions of Sections 1, 4, 6, 7, 8, 15 and 16 shall remain in full force and effect or (ii) elect to purchase the Securities which
the non-defaulting Selling Shareholders and the Company have agreed to sell hereunder. No action taken pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default.

In the event of a default by any Selling Shareholder as referred to in this Section 11, each of the Representatives, the
Company and the non-defaulting Selling Shareholders shall have the right to postpone the Closing Time or any Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required change in the Registration
Statement, the General Disclosure Package or the Prospectuses or in any other documents or arrangements.

(b) If the Company
shall fail at the Closing Time or a Date of Delivery, as the case may be, to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party;
provided, however, that the provisions of Sections 1, 4, 6, 7, 8, 15 and 16 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly
given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to (i) Merrill Lynch at One Bryant Park, New York, New York 10036, attention of Syndicate Department, with a copy to ECM

Selling Shareholders at their respective addresses set forth on Schedule B.

SECTION 13. No Advisory or Fiduciary
Relationship. Each of the Company and each Selling Shareholder, severally and not jointly, acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial
public offering price of the Securities and any related discounts and commissions, is an arms-length commercial transaction between the Company and the Selling Shareholders, on the one hand, and the several Underwriters, on the other hand,
(b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries or any Selling
Shareholder, or its respective stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or any Selling Shareholder with respect to the
offering of the Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company, any of its subsidiaries or any Selling Shareholder on other matters) and no Underwriter has any
obligation to the Company or any Selling Shareholder with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad
range of transactions that involve interests that differ from those of each of the Company and each Selling Shareholder, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of
the Securities and the Company and each of the Selling Shareholders has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 14. Parties. This Agreement shall inure to the benefit of and be binding upon
the Underwriters, the Company and the Selling Shareholders and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the
Company and the Selling Shareholders and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Selling Shareholders and
their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be

CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 17. Consent to Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this
Agreement or the transactions contemplated hereby (Related Proceedings) shall be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, unless
any such Federal court determines that it lacks jurisdiction over a Related Proceeding in which case such Related Proceeding shall be instituted in the courts of the State of New York, in each case located in the City and
County of New York, Borough of Manhattan (collectively, the Specified Courts), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any
such court (a Related Judgment), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such partys address set
forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in
the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each party not
located in the United States irrevocably appoints Corporation Service Company as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court
in the City and County of New York. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service
of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other
court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States
Foreign Sovereign Immunities Act of 1976, as amended.

SECTION 18. TIME. TIME SHALL BE OF THE ESSENCE OF THIS
AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 19. Partial
Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or
provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.



25



---

SECTION 20. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

SECTION 21. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

SECTION 22. Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder that is
expressed and paid in a currency (the Judgment Currency) other than United States dollars, the Company and the Selling Shareholders, severally and not jointly, will indemnify each Underwriter against any loss incurred by such
Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the rate of exchange at which
an Underwriter is able to purchase United States dollars with the amount of Judgment Currency actually received by such Underwriter; provided, however, that any liability of any Selling Shareholder under this Agreement shall be limited, in the
aggregate, to the Selling Shareholder Amount received by such Selling Shareholder from the sale of Securities sold by such Selling Shareholder hereunder. The foregoing indemnity shall constitute a separate and independent obligation of the Company
and the Selling Shareholders, severally and not jointly, and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term rate of exchange shall include any premiums and costs of exchange
payable in connection with the purchase of or conversion into United States dollars.

Exhibit A

FORM OF OPINION OF COMPANYS U.S. COUNSEL

TO BE DELIVERED PURSUANT TO SECTION 5(c)

(i) Each of Mitel U.S. Holdings, Inc., Mitel (Delaware), Inc. and Mitel Networks, Inc. is validly existing and in good standing under the
laws of the State of Delaware with corporate power and authority under such law to conduct its business as described in the Prospectuses.

(ii) Insofar as New York law governs the execution and delivery of the Purchase Agreement, the Purchase Agreement has been duly executed
and delivered by the Company.

(iii) No authorization, approval or other action by, and no notice to or filing with, any
United States federal or New York governmental authority or regulatory body is required for the performance by the Company of its obligations under the Purchase Agreement, except as have been obtained and are in full force and effect under the 1933
Act or as may be required by the securities or Blue Sky laws of any jurisdiction in the United States in connection with the offer and sale of the Securities by the Underwriters.

(iv) The execution and delivery by the Company of the Purchase Agreement does not, and the performance by the Company of its obligations
thereunder will not (a) result in a breach of, a default under or the acceleration of (or entitle any party to accelerate) the maturity of any obligation of the Company under, or result in or require the creation of any lien upon or security
interest in any property of the Company pursuant to the terms of, any agreement or document listed in Schedule A to such counsels opinion or (b) result in a violation of Generally Applicable Law. Generally Applicable
Law means the federal law of the United States of America, and the law of the State of New York (including the rules or regulations promulgated thereunder or pursuant thereto), that a New York lawyer exercising customary professional
diligence would reasonably be expected to recognize as being applicable to the Company, the Purchase Agreement or the transactions governed by the Purchase Agreement. Without limiting the generality of the foregoing definition of Generally
Applicable Law, the term Generally Applicable Law does not include any law, rule or regulation that is applicable to the Company, the Purchase Agreement or such transactions solely because such law, rule or regulation is part of a
regulatory regime applicable to any party to the Purchase Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate.

(v) The statements in the Prospectuses under the caption Material United States Federal Income Tax Considerations, insofar as
such statements constitute summaries of legal matters referred to therein, fairly summarize in all material respects the legal matters referred to therein.

(vi) The Company is not, and after the issuance of the Securities and the use of proceeds therefrom as contemplated in the Prospectuses
will not be, required to register as an investment company under the 1940 Act.

(vii) Assuming the validity of
such action under the laws of Canada, under the laws of the State of New York relating to submission to jurisdiction, the Company (i) has, pursuant to Section 17 of the Purchase Agreement, validly submitted to the jurisdiction of any New
York state or United States federal court located in The City of New York, New York, in any action or proceeding arising out of or with respect to the Purchase Agreement, and (ii) has validly appointed Corporation Services Company as its
authorized agent for the purposes described in Section 17 of the Purchase Agreement; and service of process effected in the manner set forth in Section 17 of the Purchase Agreement will be effective under the laws of the State of New York
in connection with any such action or proceeding.

Such counsel shall also state that (i) it has reviewed the Notice of Effectiveness on
the Commissions EDGAR system, which states that the Registration Statement became effective under the 1933 Act at [            ] [a.m.][p.m.], New York City time, on
[            ], 2010, (ii) it has reviewed the U.S. Prospectus on the Commissions EDGAR system and, based on the date of the Purchase Agreement, it appears that the U.S.
Prospectus was filed with the Commission within the time period required by Rule 424 under the 1933 Act, and (iii) on [            ], 2010, a member of the staff of the Commission
advised such counsel orally that there was no stop order suspending the effectiveness of the Registration Statement.



A-1



---

Such counsel shall also state, in a separate letter, words substantially to the following effect:

(a) each of the Registration Statement and the U.S. Prospectus (other than the financial statements and other financial data
contained therein or omitted therefrom, as to which such counsel shall not be required to express an opinion) appears on its face to be appropriately responsive in all material respects to the requirements of the 1933 Act and the applicable rules
and regulations of the Commission thereunder; and

(b) no facts came to such counsels attention which caused them to
believe that (i) the Registration Statement (other than the financial statements and other financial data contained therein or omitted therefrom, as to which such counsel has not been requested to comment), at the time it became effective,
contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the General Disclosure Package (other than the financial
statements and other financial data contained therein or omitted therefrom, as to which such counsel has not been requested to comment), as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) the U.S. Prospectus (other than the financial statements and other financial data contained therein or
omitted therefrom, as to which such counsel has not been requested to comment), as of its date or the date of such letter, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering
such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

Exhibit B

FORM OF OPINION OF COMPANYS CANADIAN COUNSEL

TO BE DELIVERED PURSUANT TO SECTION 5(d)

(i) The Company is a corporation existing in good standing under the federal laws of Canada.

(ii) The Company has the corporate power and authority to own, lease and operate its properties and to conduct its business as described
in the Prospectuses and to enter into and perform its obligations under the Purchase Agreement.

(iii) The Company is duly
qualified as an extra-provincial corporation to transact business and is in good standing in each province and territory in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business.

(iv) The authorized share capital of the Company is as set forth in the Prospectuses in the column entitled
Actual under the caption Capitalization. The Initial Securities, including the Securities to be purchased by the Underwriters from the Selling Shareholders, have been duly authorized and validly issued and are fully paid and
non-assessable.

(v) The attributes of the Common Shares conform in all material respects to the description thereof contained
in the Prospectuses.

(vi) The Securities have been duly authorized for issuance and sale to the Underwriters pursuant to the
Purchase Agreement and, when issued and delivered by the Company pursuant to the Purchase Agreement against payment of the consideration set forth in the Purchase Agreement, will be validly issued and fully paid and non-assessable.

(vii) All necessary corporate actions have been taken by the Company to authorize (A) the execution and delivery of each Canadian
Preliminary Prospectus and the Canadian Prospectus and the filing thereof with Qualifying Authorities, (B) the execution and delivery of the Registration Statement and each amendment thereto and the filing thereof with the Commission, and
(C) the execution and delivery of the Purchase Agreement and the performance by the Company of its obligations thereunder.

(viii) The Purchase Agreement has been duly authorized and, to the extent that execution and delivery are matters governed by the laws of
the Province of Ontario and the federal laws of Canada applicable therein, executed and delivered by the Company.

(ix) A
final Passport System decision document has been obtained from the Principal Regulator on behalf of itself and the other Qualifying Authorities in respect of the Final PREP Prospectus and all necessary documents have been filed, all requisite
proceedings have been taken and all necessary authorizations, approvals, permits, consents and orders have been obtained under the securities laws of each of the Qualifying Jurisdictions to qualify the distribution of the Securities to the public in
each of the Qualifying Jurisdictions through registrants registered under applicable securities laws of the Qualifying Jurisdictions who have complied with the applicable provisions of such securities laws. For purposes of this paragraph,
securities laws means the applicable securities laws and the respective regulations and rules made under those securities laws together with all applicable policy statements, blanket orders and rulings of the applicable securities
regulatory authorities.

(x) The Canadian Prospectus and each amendment or supplement to the Canadian Prospectus (other than
the financial statements and supporting schedules included therein or omitted therefrom, as to which we need express no opinion), as of its respective issue date, complied as to form in all material respects with the securities laws of the Province
of Ontario and the regulations and rules made under those securities laws together with all applicable policy statements, blanket orders and rulings of the applicable securities regulatory authorities of the Province of Ontario.

(xi) The form of certificate used to evidence the Common Shares has been duly approved and adopted by the Company and complies with any
applicable requirements of the charter and by-laws of the Company and with the provisions of the Canada Business Corporations Act relating thereto.

(xii) To our knowledge, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company
or any subsidiary is a party, or to which the property of the Company or any subsidiary is subject, before or brought by any court or governmental agency or body, domestic or foreign, which would reasonably be expected to result in a Material
Adverse Effect, or which would reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Purchase Agreement or the performance by the Company of its
obligations thereunder.



B-1



---

(xiii) To our knowledge, no order having the effect of ceasing or suspending the
distribution of the Securities or the trading in the Common Shares has been issued by any securities regulatory authority in the Qualifying Jurisdictions and no proceedings for that purpose have been instituted or are pending or contemplated.

(xiv) The information in the Prospectuses under the caption Material Canadian Federal Income Tax Considerations for
U.S. Holders and in the Registration Statement under Part II  Information Not Required in the Prospectus  Indemnification of Directors and Officers has been reviewed by us and is correct in all material respects and our
opinion in the Canadian Prospectus under the caption Eligibility for Investment is confirmed.

(xv) All
descriptions in the Prospectuses of the documents identified on Exhibit A to such counsels opinion are accurate in all material respects.

(xvi) Except for the requirement to file the Underwriting Agreement on the System for Electronic Document Analysis and Retrieval (SEDAR),
no filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency located in the Qualifying Jurisdictions is necessary or required in connection with the due
authorization, execution and delivery of the Purchase Agreement.

(xvii) All documents have been filed, all proceedings have
been taken and all legal requirements have been fulfilled by the Company to qualify the Securities for distribution and sale to the public in each of the Qualifying Jurisdictions through investment dealers or brokers registered under the applicable
laws of the Qualifying Jurisdictions who have complied with the relevant provisions of such applicable laws.

(xviii) The
execution, delivery and performance of the Purchase Agreement and the consummation of the transactions contemplated in the Purchase Agreement and in the Prospectuses (including the issuance and sale of the Securities) and compliance by the Company
with its obligations under the Purchase Agreement do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined in Section 1(a)(xv)
of the Purchase Agreement) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary pursuant to any contract, indenture, mortgage, deed of trust, loan or credit
agreement, note, lease or any other agreement or instrument identified in Exhibit B to such counsels opinion, nor will such action result in any violation of the provisions of the charter or by-laws of the Company, or any applicable Ontario
law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court of the Qualifying Jurisdictions having jurisdiction over the Company or any subsidiary or any of their respective
properties, assets or operations.

(xix) To our knowledge, there are no persons with registration rights or other similar
rights to have any securities registered pursuant to the Registration Statement or otherwise registered by the Company under the 1933 Act or qualified for distribution under Canadian Securities Laws, other than those rights that have been disclosed
in the Prospectuses and have been waived.

(xx) BNY Mellon has been duly appointed as the transfer agent and registrar for the
Common Shares.

(xxi) In any proceeding in a court of competent jurisdiction in the Province of Ontario (an Ontario
Court) for the enforcement of the Purchase Agreement, an Ontario Court would apply the laws of the State of New York (New York Law), in accordance with the parties choice of New York Law in the Purchase Agreement,
to all issues which under the laws of the Province of Ontario and the federal laws applicable in the Province of Ontario (Ontario Law) are to be determined in accordance with the chosen law of the contract, provided that:



| | (a) | The parties choice of New York Law is bona fide and legal and is not contrary to public policy, as such term is interpreted under Ontario Law
(Public Policy). We have no reason to believe that the choice of New York Law in this context is contrary to Public Policy;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



B-2



---

| | (b) | In any such proceeding, an Ontario Court:
| | --- | -----------------------------------------



| | (i) | will not take judicial notice of the provisions of New York Law but will only apply such provisions if they are pleaded and proven by expert testimony;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | will apply Ontario Law to matters which would be chararacterized as procedural under Ontario Law;
| | ---- | -------------------------------------------------------------------------------------------------



| | (iii) | will apply provisions of Ontario Law that have overriding effect;
| | ----- | -----------------------------------------------------------------



| | (iv) | will not apply any New York Law if its application would be contrary to Public Policy;
| | ---- | --------------------------------------------------------------------------------------



| | (v) | will not apply any New York Law if such application would be characterized under Ontario Law as the direct or indirect enforcement of a foreign revenue, expropriatory,
penal or other public law; and
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | will not enforce the performance of any obligation that is illegal under the laws of any jurisdiction in which the obligation is to be performed; and
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | an Ontario Court has discretion to decline to hear an action if:
| | --- | ----------------------------------------------------------------



| | (i) | it is contrary to Public Policy;
| | --- | --------------------------------



| | (ii) | it is not the proper forum to hear such an action; or
| | ---- | -----------------------------------------------------



| | (iii) | another action is properly pending before, or a decision has been rendered by, a foreign authority relating to the same cause of action.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------

We have no reason to believe that it would be contrary to Public Policy for an Ontario Court to hear an action to enforce the Purchase
Agreement in Ontario.

(xxii) In an action on a final and conclusive judgment in personam of any Specified Court that is not
impeachable as void or voidable under New York law, an Ontario Court would give effect to the appointment by the Company of Corporation Service Company as the Companys agent to receive service of process in the United States of America under
the Purchase Agreement and to the provisions in the Purchase Agreement whereby the Company submits to the non exclusive jurisdiction of any Specified Court.

(xxiii) An Ontario Court would give a judgment based upon a final and conclusive in personam judgment of a Specified Court for a
sum certain, obtained against the Company with respect to a claim arising out of the Purchase Agreement (a New York Judgment) without reconsideration of the merits provided that:



| | (a) | an action to enforce the New York Judgment must be commenced in an Ontario Court within any applicable limitation period;
| | --- | -------------------------------------------------------------------------------------------------------------------------



| | (b) | an Ontario Court has discretion to stay or decline to hear an action on the New York Judgment if such judgment is under appeal, or there is another subsisting judgment
in any jurisdiction relating to the same cause of action;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | an Ontario Court will render judgment only in Canadian dollars; and
| | --- | -------------------------------------------------------------------



| | (d) | an action in an Ontario Court on the New York Judgment may be affected by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors
rights generally;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

and provided further, an Ontario Court will not give such judgment if:



| | (e) | the New York Judgment was obtained by fraud or in a manner contrary to the principles of natural justice;
| | --- | ---------------------------------------------------------------------------------------------------------



| | (f) | the New York Judgment is for a claim which would be characterized as based on foreign revenue, expropriatory, penal or other public law under Ontario Law;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------



B-3



---

| | (g) | the New York Judgment is contrary to Public Policy or to an order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act(Canada)
or by the Competition Tribunal under the Competition Act(Canada) in respect of certain judgments referred to in such statutes; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (h) | the New York Judgment has been satisfied or is void or voidable under New York Law.
| | --- | -----------------------------------------------------------------------------------

(xxiv) All laws of the Province of Québec relating to the use of the French language (other than those relating to oral
communications as to which we express no opinion) will have been complied with in connection with the offer and sale of the Securities to purchasers in the Province of Québec if such purchasers have received copies of the Offering Documents
in the French language only or in both the English and French languages, together with, in each case, a form of order and confirmation in the French language only or in a bilingual form.

(xxv) No stamp or other issuance or transfer taxes or duties or goods and services tax or withholding taxes are payable by or on behalf
of the Underwriters to the Government of Canada or the Government of Ontario or any political subdivision thereof or any authority or agency thereof or therein having power to tax in connection with (A) the issue, sale and delivery of the
Securities by the Company to or for the respective accounts of the Underwriters or (B) the sale and delivery outside Canada by the Underwriters of the Securities in the manner contemplated in the Purchase Agreement.

Nothing has come to our attention that would lead us to believe that the Canadian Prospectus or any amendment or supplement thereto
(excluding the financial statements and related schedules and information derived therefrom or any other financial data included therein or omitted therefrom), as of its issue date, at the time any such amended or supplemented prospectus was issued
or at the Closing Time, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances in which they were
made. In addition, nothing has come to our attention that would lead us to believe that the documents included in the General Disclosure Package (which, for purposes of this paragraph shall be defined as the Issuer General Use Free Writing
Prospectuses issued at or prior to the Applicable Time, the Final PREP Prospectus and the information included on Schedule C-1 hereto, all considered together), excluding the financial statements and related schedules and information derived
therefrom or any other financial data included therein or omitted therefrom, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein not
misleading in the light of circumstances under which they were made. For purposes of this paragraph, references to material fact are to that term as defined in Section 1 of the Securities Act (Ontario). With respect to
statements contained in the General Disclosure Package, any statement contained in any of the constituent documents shall be deemed to be modified or superseded to the extent that any information contained in subsequent constituent documents
modifies or replaces such statement.

In rendering such opinion, such counsel may rely, (A) as to matters involving the application of
the laws of any jurisdiction other than the Province of Ontario, Alberta and Quebec or the federal laws of Canada, upon the opinion of local Canadian counsel of good standing (which opinion shall be dated and furnished to the Underwriters at the
Closing Time, shall be satisfactory in form and substance to counsel for the Underwriters and shall expressly state that the Underwriters may rely on such opinion as if it were addressed to them), provided that Osler, Hoskin & Harcourt LLP
shall state in their opinion that they believe that they and the Underwriters are justified in relying upon such opinion, and (B) as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions,
including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

Exhibit C

FORM OF OPINION OF COUNSEL FOR THE SELLING SHAREHOLDERS

TO BE DELIVERED PURSUANT TO SECTION 5(f)

(i) No filing with, or consent, approval, authorization, license, order, registration, qualification or decree of, any court or
governmental authority or agency located in the United States, the State of New York or the Qualifying Jurisdictions (other than the issuance of the order of the Commission declaring the Registration Statement effective, such as have been obtained
under applicable Canadian Securities Laws and such authorizations, approvals or consents as may be necessary under state securities laws, as to which we need express no opinion) is necessary or required to be obtained by such Selling Shareholder in

economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Shares or other securities, in cash or otherwise.

Notwithstanding the foregoing, and subject to the conditions below, the restrictions contained herein shall not apply to:

the Representatives may extend, by written notice to the Company, the restrictions imposed by this lock-up agreement until the expiration of the 18-day

pursuant to the previous paragraph) has expired.

The undersigned also agrees and consents to the entry of stop transfer
instructions with the Companys transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

public offering that it is no longer interested in pursuing the initial public offering at the time of such notice or (iii) if no Common Shares have been purchased and paid for pursuant to the Purchase Agreement by September 30, 2010.
