3. Purchase and Sale.

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Selling Shareholder agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Selling Shareholder, at the Public Offering Price set forth in Schedule I hereto the number of Firm Shares set forth opposite such Underwriter’s name in Schedule II hereto. On the Closing Date, the Selling Shareholder will pay, as an underwriting commission in respect of the public distribution of the Securities, to the Underwriters, the commission set forth in Schedule I hereto (the “Underwriting Commission”). Such Underwriting Commission may be paid by the Selling Shareholder to the Underwriters by setting off the Underwriting Commission payable by the Selling Shareholder to the Underwriters against the amount payable by the Underwriters to the Selling Shareholder as the purchase price for the Securities.

(b) In addition, subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Selling Shareholder hereby proportionately grants to the Underwriters, acting severally and not jointly, the option to purchase up to the number of Option Shares set forth in Schedule I hereto at the same purchase price per share to be paid by the Underwriters for the Firm Shares and at the same commission per share to be received by the Underwriters as set forth in Section 3(a) above. This option may be exercised at any time and from time to time, in whole or in part on one or more occasions, on or before the thirtieth day following the Closing Date, by written notice from Representatives to the Selling Shareholder. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time, as reasonably determined by the Representatives, when the Option Shares are to be delivered (any such date and time being herein sometimes referred to as the “Additional Closing Date”); provided, however, that no Additional Closing Date shall occur earlier than the Closing Date or earlier than the third full business day after the date on which the option shall have been exercised nor later than the fifth full business day after the date on which the option shall have been exercised. Upon any exercise of the option as to all or any

portion of the Option Shares, each Underwriter, acting severally and not jointly, agrees to purchase from the Selling Shareholder, in the same proportion as the number of Firm Shares sold to the Underwriters by the Selling Shareholder, the number of Option Shares that bears the same proportion of the total number of Option Shares then being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule II hereto (or such number increased as set forth in Section 11 hereof) bears to the total number of Firm Shares that the Underwriters have agreed to purchase hereunder, subject, however, to such adjustments to eliminate fractional shares as the Representatives in their discretion shall make. The Company, the Selling Shareholder and the Underwriters agree to work in good faith to consummate the exercise of the Option Shares in accordance with the intent underlying the foregoing provisions.

4. Delivery and Payment.

(a) Payment of the purchase price for, and delivery of the Firm Shares shall be made on the date and at the time specified in Schedule I hereto or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Selling Shareholder or as provided in Section 11 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Firm Shares shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Selling Shareholder by wire transfer payable in same-day funds to an account specified by the Selling Shareholder. Delivery of the Firm Shares shall be made through the facilities of CDS Clearing and Depository Services Inc. unless the Representatives shall otherwise instruct.

(b) Payment of the purchase price for, and delivery of the Option Shares shall be made on the Additional Closing Date or at such time on such later date as the Representatives and the Selling Shareholder shall designate, which date and time may be postponed by agreement between the Representatives and the Selling Shareholder or as provided in Section 11 hereof. Delivery of the Option Shares shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Selling Shareholder by wire transfer payable in same-day funds to an account specified by the Selling Shareholder. Delivery of the Option Shares shall be made through the facilities of CDS Clearing and Depository Services Inc. unless the Representatives shall otherwise instruct.

5. Offering by Underwriters.

(a) The several Underwriters will only offer the Securities for sale to the public as set forth in the U.S. Final Prospectus and the Canadian Final Prospectus.

(b) The Underwriters shall offer the Securities for sale to the public directly and through banking and selling group members, only as permitted by and in compliance with

Applicable Securities Laws, upon the terms and conditions set forth in the Canadian Final Prospectus and the U.S. Final Prospectus, as applicable, and in this Agreement. Each of the Underwriters hereby severally represents, warrants and covenants and will require each banking and selling group member to represent, warrant and covenant to the Underwriters that: (a) other than the Canadian Final Prospectus and the August 2017 Marketing Materials (modified as permitted by sections 9A.3(2) and 9A.3(3) of NI 44-102), it has not provided and will not without the prior written approval of the Company, the Selling Shareholder and the Representatives, provide any information in respect of the Securities to any potential investors of the Securities resident in Canada including, without limitation: (i) marketing materials in respect of the Securities; and (ii) a standard term sheet in respect of the Securities; and (b) it will provide a copy of the Canadian Base Prospectus and any applicable shelf prospectus supplement and amendment that has been filed with any marketing materials (including the August 2017 Marketing Materials) that are provided to a potential investor of the Securities resident in Canada.

(c) The Underwriters propose to offer the Securities initially at the Public Offering Price set forth in Schedule I hereto. After a reasonable effort has been made to sell all of the Securities at the price set forth in Schedule I hereto, the Underwriters may subsequently reduce and thereafter change, from time to time, the price at which the Securities are offered, provided that the Securities are not at any time offered at a price greater than the price set forth in Schedule I hereto. Any decrease in the price at which the Securities are offered will not decrease the amount of the net proceeds of the offering to the Selling Shareholder.

(d) The Underwriters will not solicit offers to purchase or sell Securities so as to require registration thereof or the filing of a prospectus, registration statement or other notice or document with respect thereto under the laws of any jurisdiction other than the Qualifying Provinces and the United States, or which could subject the Company to reporting obligations in any such jurisdiction or result in the listing of the Company’s securities on any exchange other than an exchange where such securities are listed as of the date hereof, and will require each banking and selling group member to agree with the Underwriters not to so solicit or sell, provided that the Underwriters and the banking and selling groups may offer and sell the Securities outside of the Qualifying Provinces and the United States if such offer and sale is conducted in compliance with the securities laws of such jurisdictions and does not require the Company to file any prospectus, registration statement or other notice or document in connection with such offer and sale or subject the Company to reporting obligations in any such jurisdiction or result in the listing of the Company’s securities on any exchange other than an exchange where such securities are listed as of the date hereof.

(e) Each Underwriter shall notify the Representatives, and the Representatives shall notify the Selling Shareholder and the Company, in writing, of the aggregate number of Securities sold in each of the Qualifying Provinces as soon as possible after the distribution of the Securities has been completed, and in any event no later than 30 days following the date on which such distribution has been completed.

(d) The Representatives shall have received an appropriate legal opinion, dated the Closing Date, in form and substance satisfactory to the Representatives acting reasonably, addressed to the Representatives and their counsel, of Xxxxxx, de Xxxxx L.L.P. as to compliance with the laws of Québec relating to the use of the French language in connection with the documents, including the Canadian Preliminary Prospectus, the

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) since the date of the most recent financial statements included in the Disclosure Package, the Canadian Final Prospectus and the U.S. Final Prospectus (exclusive of any supplement thereto), there has been no material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Canadian Final Prospectus and the U.S. Final Prospectus (exclusive of any supplement thereto).

(f) The Selling Shareholder shall have furnished to the Representatives a certificate of the Selling Shareholder, signed by the Chairman of the Board or the Chief Executive Officer and the principal financial or accounting officer of the Selling Shareholder, dated the Closing Date, to the effect that the representations and warranties of the Selling Shareholder in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Selling Shareholder has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date.

(g) The Company shall have requested and caused KPMG LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, (which may refer to letters previously delivered to one or more of the Representatives), dated respectively as of the Execution Time and as of the Closing Date in form and substance satisfactory to the Representatives, concerning the financial information with respect to the Company set forth in the Disclosure Package, the U.S. Final Prospectus and the Canadian Final Prospectus.

(h) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) the Canadian Final Prospectus and the U.S. Final Prospectus (exclusive of any amendment or supplement thereto), there shall not have been any change specified in the letter or letters referred to in paragraph (g) of this Section 8.

(i) Prior to the Closing Date, the Company and the Selling Shareholder shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 8 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled by the Representatives at, or at any time prior to, the Closing Date and the obligations of the Underwriters to purchase the Option Shares may be cancelled by the Representatives at, or at any time prior to, the Additional Closing Date. Notice of such cancellation shall be given to the Selling Shareholder and the Company in writing or by telephone or facsimile confirmed in writing.

9. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 8 hereof is not satisfied, because of any termination pursuant to Section 12 hereof or because of any refusal, inability or failure on the part of the Company or the Selling Shareholder to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Selling Shareholder will reimburse the Underwriters severally through the Representatives on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

10. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, the Canadian Securities Law or other Federal, state or provincial statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereto, or in the Canadian Base Prospectus, the U.S. Base Prospectus, any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Canadian Final Prospectus, the U.S. Final Prospectus, any Issuer Free Writing Prospectus, any Marketing Information, the information contained in the press release required to be prepared and filed pursuant to Section 6(c) hereto, or in any amendment thereof or

supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with the Selling Shareholder Information or written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Selling Shareholder agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, the Canadian Securities Law or other Federal, state or provincial statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereto, or in the Canadian Base Prospectus, the U.S. Base Prospectus, any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Canadian Final Prospectus, the U.S. Final Prospectus, any Issuer Free Writing Prospectus, any Marketing Information, the information contained in the press release required to be prepared and filed pursuant to Section 6(c) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, claim, damage liability, or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with the Selling Shareholder Information, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action.

(c) The Company agrees to indemnify and hold harmless the Selling Shareholder, each of the directors, officers, employees and agents of the Selling Shareholder and each person who controls the Selling Shareholder within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, the Canadian Securities Law or other Federal, state or provincial statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for

the registration of the Securities as originally filed or in any amendment thereto, or in the Canadian Base Prospectus, the U.S. Base Prospectus, any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Canadian Final Prospectus, the U.S. Final Prospectus, any Issuer Free Writing Prospectus, any Marketing Information, the information contained in the press release required to be prepared and filed pursuant to Section 6(c) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity the Selling Shareholder Information or written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(d) The Selling Shareholder agrees to indemnify and hold harmless the Company, each of the directors, officers, employees and agents of the Company and each person who controls the Company within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, the Canadian Securities Law or other Federal, state or provincial statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereto, or in the Canadian Base Prospectus, the U.S. Base Prospectus, any Canadian Preliminary Prospectus, U.S. Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Canadian Final Prospectus, the U.S. Final Prospectus, any Issuer Free Writing Prospectus, any Marketing Information, the information contained in the press release required to be prepared and filed pursuant to Section 6(c) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, claim, damage liability, or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with the Selling Shareholder Information, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action.

(e) Each Underwriter severally and not jointly agrees to indemnify and hold harmless each of the Selling Shareholder and the Company, each of their directors, each of their officers who sign the Registration Statement or the Canadian Final Prospectus, and

each person who controls the Selling Shareholder or the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnities from the Selling Shareholder and the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Selling Shareholder or the Company, as applicable, by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnities. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Selling Shareholder and the Company acknowledge that the statements set forth (i) in the paragraph under the Over-Allotment table on the cover page regarding delivery of the Securities and, under the heading “Underwriting”, (ii) the sentences related to concessions and reallowances and (iii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any Canadian Preliminary Prospectus or U.S. Preliminary Prospectus, the Canadian Final Prospectus and the U.S. Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Canadian Preliminary Prospectus or U.S. Preliminary Prospectus, the Canadian Final Prospectus and the U.S. Final Prospectus, any Issuer Free Writing Prospectus or any Marketing Information.

(f) Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraphs (a), (b), (c), (d) or (e) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a), (b), (c), (d) or (e) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of

the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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.

(g) In the event that the indemnity provided in paragraphs (a), (b), (c), (d) or (e) of this Section 10 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Selling Shareholder, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Selling Shareholder, the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Selling Shareholder or the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Selling Shareholder, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Selling Shareholder or the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Selling Shareholder and the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Selling Shareholder, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the U.S. Final Prospectus and the Canadian Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Selling Shareholder or the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Selling Shareholder, the Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (g), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 10, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Selling Shareholder or

the Company within the meaning of either the Act or the Exchange Act, each officer of the Selling Shareholder or the Company, respectively, who shall have signed the Registration Statement or the Canadian Final Prospectus, and each director of the Selling Shareholder or the Company shall have the same rights to contribution as the Selling Shareholder or the Company, subject in each case to the applicable terms and conditions of this paragraph (g).

11. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the number of Securities set forth opposite their names in Schedule II hereto bears to the aggregate number of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate number of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate number of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter, the Selling Shareholder or the Company. In the event of a default by any Underwriter as set forth in this Section 11, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement, the Canadian Final Prospectus and the U.S. Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Selling Shareholder or Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

12. Termination.

12.1 In addition to any other remedies which may be available to the Underwriters, any Underwriter shall be entitled, at its option, to terminate and cancel its obligations under this Agreement, without any liability on their or its part, in the following circumstances:

(a) Regulatory Proceeding Out. If, after the Bid Letter Time and prior to the Closing Time, an inquiry, action, suit, investigation or other proceeding is commenced or threatened or any order is made or issued under or pursuant to any law of Canada or the United States or by any other regulatory authority or stock exchange (except any such proceeding or order based solely upon the activities of any of the Underwriters), or there is any change of law or the interpretation or administration thereof, which in such Underwriter’s opinion, acting reasonably, would prevent, suspend, delay, restrict or adversely affect the trading in or the distribution of the Securities or any other securities of the Company in any of the Qualifying Provinces or in the United States; or

(b) Disaster Out. If, after the Bid Letter Time and prior to the Closing Time, there should develop, occur or come into effect or existence any event, action, state, condition or occurrence of national or international consequence or any action,

governmental law or regulation, enquiry or other occurrence of any nature whatsoever which, in such Underwriter’s sole opinion in its absolute discretion, acting reasonably, might be expected to have a significant adverse effect on the market price or value of the Securities, including, without limitation, the outbreak or escalation of hostilities involving the United States or Canada or the declaration by the United States or Canada of a national emergency or war or the occurrence of any other calamity or crisis in the United States, Canada or elsewhere; or

(c) Material Change. If, after the Bid Letter Time and prior to the Closing Time, there should occur, be discovered by the Underwriters or be announced by the Company, any material change or a change in any material fact which results or, in the sole opinion of such Underwriter, acting reasonably, might be expected to result, in the purchasers of a material number of Securities exercising their right under applicable legislation to withdraw from their purchase of Securities or, in the sole opinion of such Underwriter, might reasonably be expected to have a significant adverse effect on the market price or value of the Securities or makes it impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Disclosure Package, the U.S. Final Prospectus, the Canadian Preliminary Prospectus and the Canadian Final Prospectus; or

(d) Financial Market Out. If there is a suspension or material limitation in trading in securities generally on any of the Exchanges, a suspension or material limitation in trading in the Company’s securities on the NYSE or the TSX or a general moratorium on commercial banking activities declared by either Canadian, U.S. Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in Canada or the United States which, in each such instance, the effect is such as to make it, in the judgment of such Underwriter, acting reasonably, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Disclosure Package, the U.S. Final Prospectus, the Canadian Preliminary Prospectus and the Canadian Final Prospectus.

12.2 The rights of termination contained in Section 12.1 may be exercised by any Underwriter giving written notice thereof to the Company and the Selling Shareholder and the Representatives at any time prior to the Closing Time and are in addition to any other rights or remedies the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Company or the Selling Shareholder in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability or obligation on the part of the Underwriters to the Company or the Selling Shareholder or on the part of the Company and the Selling Shareholder to the Underwriters except in respect of any liability or obligation under any of Sections 9 and 10 which will remain in full force and effect.

13. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Selling Shareholder, the Company or their officers and of the Underwriters set forth in or made pursuant to this

Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Selling Shareholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 9 and 10 hereof shall survive the termination or cancellation of this Agreement.

15. Relationship of Underwriters with TMX Group Limited. Each of CIBC World Markets Inc., Scotia Capital Inc. and TD Securities Inc., or an affiliate thereof, owns or controls an equity interest in TMX Group Limited (“TMX Group”) and, has a nominee director serving on the TMX Group’s board of directors. As such, each such investment dealer may be considered to have an economic interest in the listing of securities on any exchange owned or operated by TMX Group, including the TSX, the TSX Venture Exchange and the Alpha Exchange. No person or company is required to obtain products or services from TMX Group or its affiliates as a condition of any such dealer supplying or continuing to supply a product or service. None of CIBC World Markets Inc., Scotia Capital Inc. and TD Securities Inc. require the Company or the Selling Shareholder to list securities on any of the exchanges.

16. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 10 hereof, and no other person will have any right or obligation hereunder.

17. No fiduciary duty. The Selling Shareholder and the Company hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Selling Shareholder and the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Selling Shareholder and the Company and (c) the Selling Shareholder’s and the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Selling Shareholder and the Company agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Selling Shareholder or the Company on related or other matters). The Selling Shareholder and the Company agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Selling Shareholder or the Company, in connection with such transaction or the process leading thereto.

18. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Selling Shareholder, the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

19. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

20. 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 indemnifying party will indemnify each indemnified party or other person to whom such amount is due against any loss incurred by such indemnified party or other person, as the case may be, as a result of any variation as between (i) the rate of exchange at which the currency amount of the country of the indemnified party is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which such indemnified party or other person, as the case may be, is able to purchase the currency, of the country of the indemnified party with the amount of the judgment currency actually received by such indemnified party or other person, as the case may be. The foregoing indemnity shall constitute a separate and independent obligation of each indemnifying party 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 the currency of the country of the indemnified party.

21. Submission to Jurisdiction; Agent for Service. Each of the Selling Shareholder and the Company hereby irrevocably agrees that any legal suit, action or proceeding arising out of or based upon this Agreement or the transaction contemplated hereby may be instituted in any state or federal court in The City of New York and in the respective courts of each party’s own corporate (or, in the case of the Underwriters, partnership) domicile with respect to actions brought against it, hereby irrevocably waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding in any state or federal court in The City of New York and hereby irrevocably submits to the jurisdiction of such courts in any such suit, action or proceeding. Each of the Selling Shareholder and the Company has appointed Torys LLP, 1114 Avenue of the Americas, 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx, 00000.0000 as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transaction contemplated hereby which may be instituted in any state or federal court in The City of New York, expressly consents to the jurisdiction of any such court in respect of any such action and waives any other requirements of or objections to personal jurisdiction with respect thereto and designates its domicile, the domicile of Torys LLP specified above and any domicile that Torys LLP may have in the future as its domicile to receive any notice hereunder (including service of process). Such appointment shall be irrevocable. If for any reason Torys LLP (or any successor agent for this purpose) shall cease to act as agent for service of process as provided above, the Selling Shareholder and the Company will promptly appoint a successor agent for this purpose reasonably acceptable to the Representatives.
