Attention:	Mr. Peter Allen

Dear Sir:

Canaccord Capital Corporation and Piper Jaffray & Co. (together, the “Lead Underwriters”), on their own behalf and as representatives of the Underwriters named in Section 10 hereof (together with the Lead Underwriters, the “Underwriters” and each individually, an “Underwriter”) understand that, subject to the terms and conditions stated herein, DragonWave Inc., a corporation incorporated under the Canada Business Corporations Act (the “Company”), proposes to issue and sell to the Underwriters an aggregate of 7,454,050 common shares in the capital of the Company (the “Treasury Shares”) and the shareholders listed on Schedule “A” hereto (the “Selling Shareholders”) propose to transfer and sell to the Underwriters in a secondary offering that number of common shares of the Company as indicated opposite such Selling Shareholder’s name in column 1 of Schedule “A” (the “Secondary Shares” and together with the Treasury Shares are collectively referred to as the “Offered Shares”) for an aggregate of 5,518,250 Secondary Shares and, an aggregate of 12,972,300 Offered Shares.

Based on the foregoing, and subject to the terms and conditions contained in this Underwriting Agreement (the “Agreement”), the Underwriters severally and not jointly, in respect of their percentages set forth in Section 10 hereof, agree to purchase from the Company and the Selling Shareholders, and by each of their acceptance hereof, the Company and the Selling Shareholders agree to sell to the Underwriters, all but not less than all of the Offered Shares on the First Closing Date (as defined in Section 2(3)) for a purchase price of U.S. $· (the “Offering Price”) per Offered Share (Cdn.$[·] per Offered Share with respect to sales to Canadian investors in Canadian dollars), being an aggregate purchase price of U.S. $· (Cdn.$[·]) against delivery of certificates representing such Offered Shares.

In addition, the Company proposes to grant to the Underwriters, in respect of their percentages set forth in Section 10 hereof, an option (the “Over-Allotment Option”), exercisable in whole or in part at any time prior to 5:00 p.m. (Ottawa time) on the day that is the 30th day following the First Closing Date (as defined in Section 2(3)), to purchase up to an aggregate additional 1,945,845 Treasury Shares (the “Additional Shares”) representing up to 15.0% of the aggregate number of Offered Shares, at the Offering Price and upon the

terms and conditions set forth herein for the purposes of covering over-allotments and for market stabilization purposes. The Offered Shares and, if and to the extent such Over-Allotment Option is exercised, the Additional Shares, are hereinafter collectively referred to as the “Shares.” The Shares shall have the material attributes described in and contemplated by the Prospectuses which are referred to below.

Section 1 Background and Interpretation.

The Company has prepared and filed with the securities regulatory authorities (the “Canadian Commissions”) in each of the provinces of Canada other than Québec (the “Qualifying Jurisdictions”) a preliminary short form base PREP prospectus dated September 24, 2009 relating to the distribution of the Shares pursuant to applicable securities laws of the Qualifying Jurisdictions and the respective rules, regulations, blanket rulings, orders and notices made thereunder and the local, uniform, national and multilateral instruments and policies adopted by the Canadian Commissions in the Qualifying Jurisdictions (collectively, as applied and interpreted, the “Canadian Securities Laws”) and in accordance with Multilateral Instrument 11-102 Passport System (“MI 11-102”) and National Policy 11-202 Process for Prospectus Reviews in Multiple Jurisdictions (“NP 11-202”). Such preliminary short form base PREP prospectus relating to the distribution of the Shares, including any documents incorporated by reference therein and any supplements or amendments thereto, is herein called the “Canadian Preliminary Prospectus.” The Company has prepared and filed the Canadian Preliminary Prospectus pursuant to the Canadian Securities Administrators’ National Instrument 44-101 - Short Form Prospectus Distributions (“NI 44-101”) and National Instrument 44-103 - - Post-Receipt Pricing (“NI 44-103”). The Ontario Securities Commission (the “Principal Regulator”) has issued a receipt for the Canadian Preliminary Prospectus and the Company has satisfied the conditions in MI 11-102 to the deemed issuance of a receipt by the Canadian Commissions for the Canadian Preliminary Prospectus in each of the other Qualifying Jurisdictions.

The Company has also prepared and filed with the United States Securities and Exchange Commission (the “SEC”) pursuant to the Canada/United States Multi-Jurisdictional Disclosure System adopted by the Canadian Commissions and the SEC (the “MJDS”), a registration statement on Form F-10 (Registration No. 333-162115) for the registration of the offering of the Shares under the United States Securities Act of 1933, as amended (together with the rules and regulations promulgated thereunder, the “Securities Act”), including the Canadian Preliminary Prospectus with such deletions therefrom and additions or changes thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the SEC. Such prospectus relating to the distribution of the Shares used in the United States, including the documents incorporated by reference therein and any supplements or amendments thereto, is herein called the “U.S. Preliminary Prospectus.” The effective date of the registration statement containing the U.S. Preliminary Prospectus (the “Initial Registration Statement”), or, if the Company files any post-effective amendment to the Initial Registration Statement, the effective date of the latest such amendment is hereinafter called the “Effective Date.” The Company has also prepared and filed with the SEC an Appointment of Agent for Service of Process and Undertaking on Form F-X at the time of the Initial Registration Statement on Form F-10 (the “Form F-X”).

In addition, the Company (a) has prepared and filed (i) with the Canadian Commissions in the Qualifying Jurisdictions, a final short form base PREP prospectus dated October 14, 2009 relating to the distribution of the Shares (including any documents incorporated therein by reference and any supplements or amendments thereto, the “Canadian Final Prospectus”), pursuant to NI 44-101 and NI 44-103, omitting the PREP Information (as hereinafter defined) in accordance with the rules and procedures set forth in NI 44-103 (the “PREP Procedures”) and (ii) with the SEC an amendment to the Initial Registration Statement to include the Canadian Final Prospectus (with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the SEC) omitting the PREP Information which most recent such amendment has become or been declared effective by the SEC (the “U.S. Final Prospectus”) and (b) will prepare and file, as promptly as possible and in any event within two business days of the execution and delivery of this Agreement, (i) with the Canadian Commissions in the Qualifying Jurisdictions, in accordance with the PREP Procedures, a supplemented prospectus setting forth the PREP Information (including any documents incorporated therein by reference and any supplements or amendments thereto, the “Canadian Supplemented Prospectus”), and (ii) with the SEC, the Canadian Supplemented Prospectus (with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the SEC) (the “U.S. Supplemented Prospectus”). The information, if any, included in the Canadian Supplemented Prospectus that is omitted from the Canadian Final Prospectus for which a final receipt has been obtained from the Canadian Commissions, but that is deemed under the PREP Procedures to be incorporated by reference into the Canadian Final Prospectus as of the date of the Canadian Supplemented Prospectus, is referred to herein as the “PREP Information.”

The registration statement on Form F-10, including any amendment thereof on or prior to the Effective Date and including the exhibits thereto, the documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the Effective Date for purposes of Section 11 under the Securities Act and including the PREP Information, is herein called the “Registration Statement.”

The U.S. Final Prospectus at the time it became effective by the SEC relating to the distribution of the Shares in the United States, including the documents incorporated by reference therein and any supplements thereto, is herein called the “U.S. Prospectus,” except that when a U.S. Supplemented Prospectus is thereafter furnished to the Underwriters, including a U.S. Supplemented Prospectus that includes the PREP Information, after the execution of this Agreement, the term “U.S. Prospectus” shall mean such U.S. Supplemented Prospectus, including the documents incorporated by reference therein and any supplements thereto.

The Canadian Final Prospectus for which a final receipt has been obtained from the Principal Regulator on behalf of the Canadian Commissions in each of the other Qualifying Jurisdictions in accordance with MI 11-102 and NP 11-202 is herein referred to as the “Canadian Prospectus,” except that, when a Canadian Supplemented Prospectus is thereafter filed with the Canadian Commissions, the term “Canadian Prospectus” shall

mean such Canadian Supplemented Prospectus, including the documents incorporated by reference therein and any amendments or supplements thereto.

The Canadian Preliminary Prospectus and the U.S. Preliminary Prospectus, including the documents incorporated by reference therein and any supplements or amendments thereto that omits the PREP Information are herein collectively sometimes referred to as the “Preliminary Prospectuses.” The U.S. Prospectus and the Canadian Prospectus are hereinafter collectively sometimes referred to as the “Prospectuses.” The U.S. Supplemented Prospectus and the Canadian Supplemented Prospectus are hereinafter collectively sometimes referred to as the “Supplemented Prospectuses.”

Any amendment to the U.S Prospectus or the Canadian Prospectus (including any document incorporated by reference therein), and any amended or supplemented prospectus or auxiliary material, information, evidence, return, report, application, statement or document that is filed by or on behalf of the Company with the Canadian Commissions in the Qualifying Jurisdictions or with the SEC after the Canadian Supplemented Prospectus and the U.S. Supplemented Prospectus have been filed and prior to the expiry of the period of distribution of the Shares, is referred to herein collectively as the “Supplementary Material.”

As used herein, the “Applicable Time” is [·] (Ottawa time) on October ·, 2009. As used herein, a “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, and a “Time of Sale Prospectus” means the Canadian Final Prospectus and the U.S. Final Prospectus together with the information and the free writing prospectuses, if any, identified in Schedule “B” hereto, and each “road show” (as defined in Rule 433 under the Securities Act), if any, related to the offering of the Shares contemplated hereby that is a “written communication” (as defined in Rule 405 under the Securities Act) (each such road show, a “Road Show”).

As used herein, the terms “Registration Statement,” “Preliminary Prospectuses,” “Time of Sale Prospectus” and “Prospectuses” shall include the documents incorporated and deemed to be incorporated by reference therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents.

All references in this Agreement to the Registration Statement, the U.S. Preliminary Prospectus or the U.S. Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”). All references in this Agreement to Financial Statements (as defined in Section 3(o)) and schedules and other information which are “contained,” “included” or “stated” in the Registration Statement, the U.S. Preliminary Prospectus, the Time of Sale Prospectus or the U.S. Prospectus (and all other references of like import) shall be deemed to mean and include all such Financial Statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the U.S. Preliminary Prospectus, the Time of Sale Prospectus or the U.S. Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the U.S. Preliminary Prospectus, the Time of Sale Prospectus or the U.S. Prospectus, as the case may be, shall be deemed to mean and

include the filing of any document under the United States Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”) or otherwise that is or is deemed to be incorporated by reference in the Registration Statement, the U.S. Preliminary Prospectus, the Time of Sale Prospectus or the U.S. Prospectus, as the case may be.

As used herein, “business day” shall mean a day on which each of the NASDAQ Global Market and the Toronto Stock Exchange is open for trading. The terms “herein,” “hereof,” “hereto,” “hereinafter” and similar terms, as used in this Agreement, shall in each case refer to this Agreement as a whole and not to any particular section, paragraph, sentence or other subdivision of this Agreement. The term “or,” as used herein, is not exclusive.

The Underwriters shall offer the Shares for sale to the public directly and through other duly registered investment dealers and brokers in the Qualifying Jurisdictions and the United States only as permitted by applicable law and upon the terms and conditions set forth in the Prospectuses and this Agreement. The Underwriters agree that they will not, directly or indirectly, distribute the Registration Statement, the Canadian Preliminary Prospectus, the Canadian Prospectus, the U.S. Preliminary Prospectus or the U.S. Prospectus or publish any prospectus, circular, advertisement or other offering material in any jurisdiction other than the Qualifying Jurisdictions or such states of the United States in which the Shares are duly qualified under United States federal and applicable United States state securities laws, in such manner as to require registration of the Shares or the filing of a prospectus or any similar document with respect to the Shares by the Company therein or subject the Company to ongoing periodic reporting obligations in such jurisdiction pursuant to the securities laws of such jurisdiction. The Underwriters agree that each of the Underwriters that is not registered as a broker-dealer under Section 15 of the Exchange Act, will not offer or sell any Shares in, or to persons who are nationals or residents of, the United States other than through one of its United States registered broker-dealer affiliates or otherwise in compliance with Rule 15a-6 under the Exchange Act. Sales of Shares in the Qualifying Jurisdictions may be made only by or through a dealer appropriately registered under applicable Canadian Securities Laws or in circumstances where an exemption from the Canadian registered dealer requirements is available. Notwithstanding the foregoing provisions of this paragraph, an Underwriter will not be liable to the Company or the Selling Shareholders under this Agreement with respect to a default by another Underwriter under this paragraph.

Section 2 Purchase, Sale, Payment and Delivery of the Shares.

The Company and the Selling Shareholders hereby confirm their agreement with the Underwriters concerning the purchase and sale of the Shares as follows:

(1) Public Offering of the Shares. The Lead Underwriters hereby advise the Company and the Selling Shareholders that the Underwriters intend to offer for sale to the public, initially on the terms set forth in the Time of Sale Prospectus and each Prospectus, their respective portions of the Shares as soon after this Agreement has been executed and the Registration Statement has been declared effective as the Lead Underwriters, in their sole judgment, have determined is advisable and practicable.

The Underwriters may from time to time, after the Shares have initially been offered to the public, increase or decrease the Offering Price in the United States to such extent as may be determined by the Underwriters, and vary the Offering Price in Canada to the extent permitted by Canadian Securities Laws.

(2) Underwriters’ Commission. In consideration of the Agreement of the Underwriters to purchase the Shares and to offer them to the public, the Company agrees to pay to the Underwriters (i) at the First Closing Date (as defined in Section 2(3)) an underwriting fee equal to 5.75% of the gross proceeds from the sale of the Treasury Shares and (ii) at the Option Closing Date (as defined in Section 2(4)) an underwriting fee equal to 5.75% of the gross proceeds from the sale of the Additional Shares, and the Selling Shareholders agree to pay to the Underwriters at the First Closing Date an underwriting fee equal to 5.75% of the gross proceeds from the sale of the Secondary Shares (together, the “Underwriters’ Commission”). The Company will not receive any of the net proceeds to the Selling Shareholders from the sale of the Secondary Shares. The Underwriters’ Commission may be deducted by the Underwriters from the proceeds of sale of the Offered Shares on the First Closing Date or the proceeds of sale of the Additional Shares on the Option Closing Date, as applicable. In addition, the Company agrees to pay to the Underwriters, and in the manner specified by the Lead Underwriters, all fees, disbursements and expenses incurred by the Underwriters in accordance with the provisions in Section 6 hereof.

(3) The First Closing Date in respect of the Offered Shares. Payment of the Offering Price for the Offered Shares shall be made to the Company and each of the Selling Shareholders, respectively, as the case may be, by wire transfer against delivery of certificates for the Offered Shares to the Lead Underwriters on behalf of the Underwriters through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters, as applicable. Such payment and delivery shall be made at [8:00 a.m., Ottawa time, on October 20, 2009] (the “First Closing Date”) (unless another time shall be agreed to by the Lead Underwriters and the Company or unless postponed in accordance with the provisions of Section 10 hereof). Electronic transfer of the Offered Shares shall be made to the Lead Underwriters at the First Closing Date in such names and in such denominations as specified by the Lead Underwriters on behalf of the Underwriters. It is understood that the Lead Underwriters have been authorized, for their own account and the accounts of the non-defaulting Underwriters, to accept delivery of and receipt for, and make payment of the Offering Price for, the Offered Shares and any Additional Shares the Underwriters have agreed to purchase (subject to such adjustment as the Lead Underwriters may determine to eliminate fractional shares and subject to adjustment in accordance with Section 10 hereof). The Lead Underwriters, individually and not as the Lead Underwriters of the Underwriters, may (but shall not be obligated to) make payment for any Shares to be purchased by any Underwriter whose funds shall not have been received by the Lead Underwriters by the First Closing Date or the applicable Option Closing Date (as defined in Section 2(4)), as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(4) The Additional Shares and the Option Closing Date. In addition, the Company hereby grants to the Underwriters the Over-Allotment Option to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions set forth herein, the Underwriters shall have the right to purchase, severally and not jointly, from the Company, all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Offering Shares, at the same Offering Price per Offered Share to be paid by the Underwriters to the Company for the Offered Shares. The Over-Allotment Option granted hereunder may be exercised at any time and from time to time in whole or in part upon notice by the Lead Underwriters to the Company, which notice may be given at any time prior to 5:00 p.m. (Ottawa time) on the day that is the 30th day from the First Closing Date (the “Notice of Exercise”). The Notice of Exercise shall set forth (i) the aggregate number of Additional Shares as to which the Underwriters are exercising the option, (ii) the names and denominations in which the certificates for the Additional Shares are to be registered through the facilities of DTC, and (iii) the time, date and place at which payment and delivery are to be made in respect of the Additional Shares (which time and date may be simultaneous with, but not earlier than the First Closing Date; and in the event that such time and date are simultaneous with the First Closing Date, the term “First Closing Date” shall refer to the time and date of delivery of certificates for the Offered Shares and such Additional Shares through the facilities of DTC). Any such time and date of delivery, if subsequent to the First Closing Date, is called an “Option Closing Date” and shall be determined by the Lead Underwriters and shall not be earlier than three nor later than five full business days after the date of delivery of such Notice of Exercise. If any Additional Shares are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustment as the Lead Underwriters may determine to eliminate fractional shares) that bears the same proportion to the total number of Additional Shares to be purchased as the number of Offered Shares set forth opposite the name of such Underwriter in Section 10 hereof bears to the total number of Offered Shares subject to adjustment in accordance with Section 10 hereof. The Lead Underwriters may cancel the Over-Allotment Option at any time prior to its expiration by giving written notice of such cancellation to the Company.

(5) Delivery of the Shares and Closing Mechanics. The Company and each Selling Shareholder shall deliver, or cause to be delivered, to the Lead Underwriters for the accounts of the Underwriters certificates for the Offered Shares at the First Closing Date, against the irrevocable release of a wire transfer of immediately available funds for the amount of the Offering Price therefor. The Company shall also deliver, or cause to be delivered, to the Lead Underwriters for the accounts of the Underwriters, certificates for the Additional Shares the Underwriters have agreed to purchase at the First Closing Date or the applicable Option Closing Date, as the case may be, against the irrevocable release of a wire transfer of immediately available funds for the amount of the Offering Price therefor. The certificates for the Shares shall be registered in such names and denominations as the Lead Underwriters shall have requested at least one full business day prior to the First Closing Date (or the applicable Option Closing Date, as the case may be). Deliveries of the documents

described in Section 7 hereof with respect to the purchase of the Shares shall be made at the offices of Fraser Milner Casgrain LLP, 1420-99 Bank Street, Ottawa, Ontario, K1P 1H4 at 8:00 a.m., Ottawa time, or at such other place as the Lead Underwriters and the Company may agree, on the First Closing Date or the Option Closing Date, as the case may be. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

(ll) Title to Properties. The Company and each of its Subsidiaries has good and marketable title to all property and other assets reflected as owned in the Financial Statements incorporated by reference in each Applicable Prospectus, in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, adverse claims and other defects, except such as do not materially and adversely affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company or such Subsidiary, other than the security interest over all of the present and after-acquired personal property of the Company and/or its Subsidiaries granted to the Company’s principal banker, Comerica Bank, to secure the operating credit facility described in the Applicable Prospectuses under the caption “Management’s Discussion & Analysis of Financial Condition and Results of Operations.” The real property, improvements, equipment and personal property held under lease by the Company or any Subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such Subsidiary.

to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them except as may be being contested in good faith and by appropriate proceedings, except for such failure to pay as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Change. The Company has made adequate charges, accruals and reserves in the Financial Statements incorporated by reference in each Applicable Prospectus in respect of all United States federal, Canadian federal, state, provincial and foreign income and franchise taxes for all periods as to which the tax liability of the Company or any of its consolidated Subsidiaries has not been finally determined.

Neither the Company nor

any Subsidiary has been denied any insurance coverage which it has sought or for which it has applied in the past two years.

Each of the Selling Shareholders, severally and not jointly, agree to indemnify and hold harmless the Indemnified Parties and the Company from and against any and all Claims to which any Indemnified Party may become subject or otherwise involved in any capacity insofar as the Claims relate to, are caused by, result from, arise out of or are based upon, directly or indirectly, or as a consequence of: (i) any misrepresentation or alleged misrepresentation within the meaning of Canadian Securities Laws, an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof for purposes of Section 11 under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein, or necessary to make the statements therein, not misleading, where such misrepresentation or alleged misrepresentation, untrue statement, alleged untrue statement, omission or alleged omission, is attributable to information or statements relating to the Selling Shareholder and is provided by the Selling Shareholder specifically for inclusion in the Registration Statement (the “Selling Shareholder Information”); (ii) any misrepresentation or alleged misrepresentation within the meaning of Canadian Securities Laws, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectuses, the Time of Sale Prospectus, any such free writing prospectus, the U.S. Prospectus, the Canadian Prospectus or any Supplementary Material (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, where such misrepresentation or alleged misrepresentation, untrue statement, alleged untrue statement, omission or alleged omission, is attributable to the Selling Shareholder Information; (iii) any order made or enquiry, investigation or proceeding, whether formal or informal, commenced, announced or threatened by any securities regulatory authority or any other competent authority based upon any untrue statement or omission or alleged untrue statement or alleged omission or any misrepresentation or alleged misrepresentation referred to in clauses (i) or (ii), or otherwise filed with or delivered to any securities commission or similar regulatory authority, or based upon any failure of the Selling Shareholder to comply with the Canadian Securities Laws, the Securities Act and the Exchange Act (other than any failure or alleged failure to comply by an Underwriter), preventing or restricting the trading in or the sale or distribution of the Secondary Shares in any of the Qualifying Jurisdictions or in the United States, (iv) the breach by the Selling Shareholder of any representation or warranty in this Agreement or the failure of the Selling Shareholder to comply with any of its obligations under this Agreement, or (v) the transfer, sale, offering and delivery by the Selling Shareholder of the Secondary Shares pursuant to the provisions of this Agreement; provided, however, that the foregoing indemnity agreement may not be relied upon by any Indemnified Party in respect of any losses that a court of competent jurisdiction has determined in a final judgment which has become non-appealable results from the gross negligence, bad faith, fraud or wilful misconduct of that Indemnified Party. Each of the Selling Shareholders will severally and not jointly reimburse the Indemnified Parties promptly upon demand for any legal or other expenses reasonably incurred by them

in connection with investigating, defending, settling, compromising or paying any such Claim contemplated by this Section 11(2), as incurred. Notwithstanding the foregoing, clause (i) of this Section 11(2) shall apply to each Selling Shareholder only to the extent that the statements or omissions in or from the Registration Statement, the Preliminary Prospectuses, the Time of Sale Prospectus, any such free writing prospectus, the U.S. Prospectus, the Canadian Prospectus or any Supplementary Material (or any amendment or supplement thereto) were made in conformity with the Selling Shareholder Information, which consists of the information under the captions “Principal Shareholders” and “Selling Shareholders” in each Applicable Prospectus; provided, however, that save in the event of gross negligence, bad faith, fraud, wilful misconduct or deliberate non-disclosure, the liability of each Selling Shareholder under this Agreement shall be limited to an amount equal to the total gross proceeds to such Selling Shareholder from the sale of the Secondary Shares pursuant to the provisions of this Agreement.

(3) Notification. If any matter or thing contemplated by this Section 11 shall be asserted against any Indemnified Party in respect of which indemnification is or might reasonably be considered to be provided, such Indemnified Party will notify the Indemnifying Party and the Selling Shareholders as soon as possible and, in any event on a timely basis, of the nature of such Claim and the Indemnifying Party or the Selling Shareholder, as the case may be, shall be entitled (but not required) to assume the defence of any suit brought to enforce such Claim; provided, however, that the defence shall be through legal counsel acceptable to the Indemnified Party, acting reasonably, and that no settlement may be made by the Indemnifying Party or the Selling Shareholder or the Indemnified Party without the prior written consent of the other, such consent to not be unreasonably withheld. Failure or delay by the Indemnified Party to so notify shall not relieve the Indemnifying Party or Selling Shareholder, as the case may be, of its obligation of indemnification hereunder unless (and only to the extent that) such failure or delay results in forfeiture by the Indemnifying Party or Selling Shareholder, as the case may be, of substantive rights or defences.

(4) Settlement. The Indemnifying Party or the Selling Shareholder, as the case may be, shall not, without the prior written consent of the Underwriters, which shall not be unreasonably withheld, settle or compromise or consent to the entry of any judgment in any pending or threatened Claim in respect of which indemnification may be sought hereunder (whether or not the Indemnified Parties are a party to such Claim), unless such settlement, compromise or consent includes an unconditional release of each of the Indemnified Parties from all liability arising out of such Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be liable for the settlement of any Claim in respect of which indemnity may be sought hereunder effected without its written consent, which consent shall not be unreasonably withheld.

(5) Retaining Counsel. In any such Claim, the Indemnified Party shall have the right to retain other counsel to act on the Indemnified Party’s behalf, provided that the fees and disbursements of such other counsel shall be paid by the Indemnified Party,

unless: (i) the Indemnifying Party or the Selling Shareholder, as the case may be, and the Indemnified Party mutually agree to retain such other counsel, (ii) the Indemnifying Party or the Selling Shareholder, as the case may be, has not assumed the defence of the action within a reasonable period of time after receiving notice of the Claim, (iii) in the opinion of counsel, there are one or more defences available to the Indemnified Party which are different from or in addition to those available to the Indemnifying Party or the Selling Shareholder, as the case may be or (iv) in the opinion of counsel, the named parties to any such Claim (including any third or implicated party) include both the Indemnified Party on the one hand and the Indemnifying Party or the Selling Shareholder, as applicable, on the other hand, and the representation of the Company or the Selling Shareholder, as applicable, and the Indemnified Party by the same counsel would be inappropriate due to actual or potential conflicting interests, in which event such fees and disbursements shall be paid by the Indemnifying Party or the Selling Shareholder, as applicable, to the extent that they have been reasonably incurred.

(6) Expenses. The Indemnifying Party and the Selling Shareholder agree that if any action, suit, proceeding or claim shall be brought against, or an investigation commenced in respect of, the Indemnifying Party or the Selling Shareholder or the Indemnifying Party or the Selling Shareholder and any Underwriter and personnel of any Underwriter shall be required to testify, participate or respond in respect of or in connection with this Agreement, the Underwriters shall have the right to employ their own counsel in connection therewith and the Indemnifying Party or Selling Shareholders, as applicable, will reimburse the Underwriters monthly for reasonable out-of-pocket expenses as may be incurred, including fees and disbursements of the Underwriters’ counsel.

(7) Right of Indemnity in Favour of Others. With respect to any Indemnified Party who is not a party to this Agreement, it is the intention of the Company and the Selling Shareholders to constitute the Underwriters as trustee for such Indemnified Party of the rights and benefits of this Section 11 and the Underwriters agree to accept such trust and to hold the rights and benefits of this Section 11 in trust for and on behalf of such Indemnified Party.

(8) Responsibility. Except in respect of statements relating solely to the Underwriters or expressly agreed by the Underwriters in writing, neither the Underwriters nor any of their affiliates or advisers will be responsible to the Company, the Selling Shareholders or to any other person responsible for the Applicable Prospectuses for verifying the accuracy or fairness of the information published therein or otherwise published by the Company or the Selling Shareholders in connection with the offering and sale of the Shares.

(9) Non-Prejudice. The indemnity provisions set forth in this Section 11 and the contribution provisions set forth in Section 12 and the obligations of the Company and the Selling Shareholders thereunder shall be in addition to any liability which the Company and the Selling Shareholders may otherwise have and shall be binding upon and enure to the benefit of any successors, assigns, heirs and personal

representatives of the Company, the Selling Shareholders and the Indemnified Parties.

Section 12 Contribution.

(1) Contribution. If the indemnification provided for in Section 11 hereof is unavailable to or unenforceable by an Indemnified Party or insufficient to hold an Indemnified Party harmless in respect of any Claims (as defined in Section 11(1)), then the Company and the Selling Shareholders (each, an “Indemnifier”) shall contribute to the amount paid or payable by such Indemnified Party as a result of such Claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifier on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above 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 Indemnifier on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Claims, as well as any other relevant equitable considerations. The relative benefits received by the Indemnifier on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering of the Shares (net of Underwriters’ Commission but before deducting expenses) received by the Indemnifier, and the total Underwriters’ Commission received by the Underwriters, bear to the gross proceeds of the offering of the Shares. The relative fault of the Indemnifier on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Indemnifier or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission or misrepresentation referred to in Section 11. The Underwriters’ obligations to contribute pursuant to this Section 12 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective names in Section 10 hereof. The Underwriters shall not in any event be liable to contribute, in the aggregate, any amounts in excess of the Underwriters’ Commission or any portion of such commission actually received by such Underwriter in connection with the Shares underwritten by it and distributed to the public. The amount paid or payable by an Indemnified Party as a result of the Claims referred to above shall be deemed to include, subject to the limitations set forth in Section 11, any legal or other out-of-pocket expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such losses, claims, damages, liabilities, costs or expenses, whether or not resulting in any such Claims.

(2) Right of Contribution in Addition to Other Rights. The rights to contribution provided in this Section 12 shall be in addition to and not in derogation of any other right to contribution which an Indemnified Party may have by statute or otherwise at law.

(3) Right of Contribution in Favour of Others. With respect to any Indemnified Party who is not a party to this Agreement, it is the intention of the Company and the Selling Shareholders to constitute the Underwriters as trustee for such Indemnified Party of the rights and benefits of this Section 12 and the Underwriters agree to accept such trust and to hold the rights and benefits of this section in trust for and on behalf of such Indemnified Party.

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

Section 13 Notification to the Underwriters.

The Company and each of the Selling Shareholders severally and not jointly undertakes to notify the Lead Underwriters immediately if it comes to its knowledge at any time up to the First Closing Date that any of the representations and warranties in this Agreement was not true or accurate or was misleading in any material respect when given or made or has ceased to be true or accurate in any material respect or has become misleading by reference to the facts or circumstances from time to time subsisting and of all other information of which it becomes aware which may give rise to an obligation to prepare and file Supplementary Material. If, at any time prior to the First Closing Date, the Lead Underwriters shall receive notification pursuant to this section or they shall otherwise become aware that any of the representations and warranties in this Agreement is or has become or is likely to become untrue, inaccurate or misleading in any material respect, the Lead Underwriters may (without prejudice to their right to terminate their obligations under this Agreement pursuant to Section 9) require the Company at its own expense to make or cause to be made such announcement as the Underwriters may reasonably determine. The Selling Shareholders are not obligated to give notification to the Lead Underwriters pursuant to this Section 13 if the Company has made a notification to the Lead Underwriters regarding the same subject matter.

Section 14 Representations and Indemnities to Survive Delivery.

The representations, warranties and covenants of the Company, the Selling Shareholders and the Underwriters contained in this Agreement and in any certificate delivered pursuant to this Agreement or in connection with the purchase and sale of the Shares shall survive the delivery of and payment for the Shares sold hereunder and shall continue in full force and effect unaffected by any subsequent disposition of the Shares by the Underwriters or the termination of the Underwriters’ obligations and shall not be limited or prejudiced by any investigation made by or on behalf of the Underwriters in connection with the preparation of the Prospectuses, any amendments or supplements related thereto or the distribution of the Shares.

Section 15 No Advisory or Fiduciary Relationship.

The Company and the Selling Shareholders acknowledge and agree that (a) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the Offering Price of the Shares 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 Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its shareholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favour of the Company or the Selling Shareholders with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company or the Selling Shareholders with respect to the offering contemplated hereby 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 the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Selling Shareholders have consulted their own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.
