2. Purchase and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at the purchase price set forth in Schedule I hereto the principal amount of the Securities set forth opposite such Underwriter’s name in Schedule II hereto.

4. Offering by Underwriters.

(a) It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the U.S. Final Prospectus and the Underwriters hereby agree that they will not distribute Securities under the U.S. Final Prospectus or the Canadian Final Prospectus to a purchaser resident in Canada; provided, however, that either prospectus may form part of the Canadian offering memorandum in respect of the offer and sale of Securities on a private placement basis in Canada in accordance with Section 4(b) referred to in Section 4(b) of this Agreement. The several Underwriters may also offer the Securities to purchasers located or resident in Canada on a private placement basis pursuant to exemptions from the prospectus requirements of Canadian securities laws as set forth in Section 4(b) of this Agreement.

(b) The Underwriters shall provide each purchaser located in Canada or that is a resident of Canada with a copy of the form of Canadian offering memorandum approved by the Company and the Underwriters, pursuant to which each such purchaser will make the deemed representations and warranties contained therein for the benefit of the Company and the Underwriters. The Underwriters agree that they will distribute the Securities to residents in Canada only on a private placement basis to non-individual purchasers located or resident in Xxxxxxx, Xxxxxx, Xxxxxxx or British Columbia who qualify as both “accredited investors” as defined in Section 73.3 of the Securities Act (Ontario) or NI 45-106 and as “permitted clients” within the meaning of National Instrument 31-103 – Registration Requirements, Exemptions and Ongoing Registrant Obligations and further represent and agree that, except in respect of activities relating to the private placement of Securities in Canada in accordance with the foregoing, they have not undertaken and will not undertake any advertisement or solicitation respecting the Securities to a prospective purchaser resident in Canada. Each Underwriter will provide the Company with the information pertaining to each purchaser of the Securities in Canada as is required to be disclosed in Schedule 1 of Form 45-106F1 under NI 45-106 within three (3) business days after the Closing Date.

(c) The Underwriters hereby further represent and agree that they have not undertaken and will not undertake any advertisement or solicitation in furtherance of the public distribution of the Securities in Canada (which, for certainty, does not include any activities undertaken in connection with the purchases and sales of Securities completed to residents of Canada on a private placement basis in accordance with Section 4(b) of this Agreement).

5. Agreements. The Company agrees with the several Underwriters that:

(a) Prior to the termination of the offering of the Securities, the Company will not file any amendment to the Registration Statement, the Canadian Base Prospectus, the U.S. Base Prospectus, the Canadian Preliminary Prospectus, the U.S. Preliminary Prospectus, the Canadian Final Prospectus or the U.S. Final Prospectus, or any amended Canadian Base Prospectus, U.S. Base Prospectus, Canadian Preliminary Prospectus, U.S. Preliminary Prospectus, Canadian Final Prospectus or U.S. Final Prospectus unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Company will cause the Canadian Final Prospectus and the U.S. Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives and shall file (i) such Canadian Final Prospectus with the ASC in accordance with the Shelf Procedures and (ii) such U.S. Final Prospectus with the SEC pursuant to General Instruction II.L of Form F-10 not later than the SEC’s close of business on the Business Day following the date of the filing thereof with the ASC. The Company will promptly file all reports required to be filed by it with the ASC pursuant to Alberta Securities Law and the SEC pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act for so long as the delivery of a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) is required under the Securities Act in connection with the offering or sale of the Securities. During such same period, the Company will advise the Representatives, promptly after it receives notice thereof, (i) of the time when any amendment to the Canadian Final Prospectus has been filed or receipted, (ii) when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Canadian Base Prospectus or any amended Canadian Final Prospectus or U.S. Final Prospectus has been filed with the ASC or the SEC, (iii) of the issuance by the ASC (or other Canadian securities regulatory authorities) or the SEC of any stop order or cease trade order or of any order preventing or suspending the use of any prospectus relating to the Securities, (iv) of the suspension of the qualification of such Securities for offering or sale in any jurisdiction, (v) of the initiation or threatening of any proceeding for any such purpose, or (vi) of any request by the ASC or the SEC for the amending or supplementing of the Registration Statement, the Canadian Final Prospectus or the U.S. Final Prospectus or for additional information relating to the Securities. The Company will use its reasonable efforts to prevent the issuance of any such stop order or cease trade order or any such order preventing or suspending the use of any prospectus relating to the Securities or the suspension of any such qualification and, in the event of the issuance of any such stop order or cease trade order or of any such order preventing or suspending the use of any prospectus relating to the Securities or suspending any such qualification, to use its reasonable efforts to obtain as soon as possible the withdrawal of such order.

(b) The Company will prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof, in the form approved by the Representatives and attached as Schedule IV hereto and will file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(c) During the period from the date hereof until completion of the distribution of the Securities, the Company shall promptly notify the Representatives in writing of:

(i) any material change (actual, anticipated, contemplated or threatened, financial or otherwise) in the business, affairs, operations, assets, liabilities (contingent or otherwise) or capital of the Company and the Company subsidiaries on a consolidated basis;

(ii) any material fact that has arisen or has been discovered which would have been required to have been stated in the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package, each as then amended or supplemented, had the fact arisen or been discovered on, or prior to, the date of the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package, as the case may be; and

(iii) any change in any material fact (which for the purposes of this Agreement shall be deemed to include the disclosure of any previously undisclosed material fact) in the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package,

which change or new material fact is, or may be, of such a nature as:

(i) to render the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package, as they exist taken together in their entirety immediately prior to such change or material fact, misleading or untrue or would result in any of such documents, as they exist taken together in their entirety immediately prior to such change or material fact, containing a misrepresentation;

(ii) to cause the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package, each as then supplemented, to include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading;

(iii) to make it necessary to amend the Registration Statement, file a new registration statement or supplement the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package to comply with the Securities Act or the Exchange Act, or the respective rules thereunder, including in connection with use or delivery of the Canadian Final Prospectus or the U.S. Final Prospectus;

(iv) would result in the Canadian Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package, as they exist taken together in their entirety immediately prior to such change or material fact, not complying with any Alberta Securities Law; or

(v) could reasonably be expected to have a Material Adverse Effect.

The Company shall in good faith discuss with the Representatives any material fact or material change (actual, anticipated, contemplated or threatened, financial or otherwise) which is of such a nature that there is reasonable doubt as to whether notice in writing need be given to the Representatives pursuant to this Section. During the period from the date hereof until completion of the distribution of the Securities and at any time when a prospectus relating to the Securities is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company shall promptly comply with all

applicable filing and other requirements under the Securities Act and Alberta Securities Law arising as a result of any material change, fact, event or circumstance referred to in this Section and shall promptly, and in any event within any time limit prescribed under the Securities Act and applicable Alberta Securities Law, (i) prepare and file with the ASC and the SEC, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (ii) use its reasonable efforts to have any amendment to the Registration Statement or new registration statement become effective as soon as practicable in order to avoid any disruption in use of the Canadian Final Prospectus or U.S. Final Prospectus and (iii) thereafter supply any supplemented Canadian Final Prospectus, U.S. Final Prospectus and Disclosure Package to you in such quantities as you may reasonably request and shall comply with its obligations hereunder in respect thereof.

(d) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158.

(e) The Company will furnish to the Representatives and counsel for the Underwriters, without charge, signed copies (which may be electronic copies) of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Canadian Base Prospectus, U.S. Base Prospectus, Canadian Final Prospectus, U.S. Final Prospectus, and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request. If applicable, the Company will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject; provided further that the Securities may not be offered in any jurisdiction other than the provinces and territories of Canada or the United States in a manner that would require the Company to comply with any registration, prospectus, continuous disclosure, filing or other similar requirements under the applicable securities laws of such jurisdiction, other than with respect to filing reports of exempt distribution with Canadian securities regulatory authorities.

(g) The Company agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the SEC or retained by the Company under Rule 433, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereto; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto and any electronic road show. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will

treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the SEC, legending and record keeping.

(h) The Company will not, without the prior written consent of BofA Securities, Inc., offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any debt securities similar to the Securities issued or guaranteed by the Company (other than the Securities) or publicly announce an intention to effect any such transaction, until the Business Day set forth on Schedule I hereto.

(i) The Company agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the SEC of the Registration Statement (including financial statements and exhibits thereto), the Form F-X, the Form T-1, each of the Canadian Base Prospectus, the U.S. Base Prospectus, the Canadian Preliminary Prospectus, the U.S. Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) if applicable, the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each of the Canadian Base Prospectus, the U.S. Base Prospectus, the Canadian Preliminary Prospectus, the U.S. Preliminary Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (v) all expenses in connection with the registration or qualification of the Securities for offering and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification and in connection with any Blue Sky memoranda); (vi) any filings required to be made with the Financial Industry Regulatory Authority, Inc. or the ASC (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (vii) any fees charged by securities rating services for rating the Securities; (viii) the fees and expenses of the Trustee and the reasonable fees and disbursements of counsel for the Trustee in connection with any Indenture and the Securities; (ix) the fees and expenses of the Company’s accountants and the fees and expenses of counsel (including local and special counsel) for the Company and (x) all other reasonable costs and expenses incident to the performance by the Company of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that except as provided in this Section, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel.

(j) The Company will cooperate with the Underwriters and use its commercially reasonable efforts to permit the Securities to be eligible for clearance and settlement through the facilities of DTC.

(k) The Company will use the proceeds received by it from the sale of the Securities in the manner specified in the Canadian Final Prospectus, U.S. Final Prospectus and Disclosure Package under the caption “Use of Proceeds.”

(l) The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(m) The Company will deliver to the Representatives, on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as the Representatives may reasonably request in connection with the verification of the foregoing certification.

(n) The Company will timely file all documents required to be filed with Canadian securities regulatory authorities in connection with the issuance and sale of the Securities to purchasers resident in Canada in accordance with applicable Canadian securities laws, including, without limitation, any Form 45-106F1 prescribed by NI 45-106.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, their affiliates involved in the distribution of the Securities, the directors and officers of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities 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 Securities Act, the Exchange Act or other Federal or state 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 thereof, or in the Canadian Preliminary Prospectus, the U.S. Preliminary Prospectus, the Canadian Base Prospectus, the U.S. Base Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) 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 as such expenses are incurred; 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 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) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in

the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that the following statements set forth under the heading “Underwriting (Conflicts of Interest)” in the Registration Statement, the Canadian Final Prospectus, the U.S. Final Prospectus and the Disclosure Package constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in Registration Statement, the Canadian Final Prospectus, the U.S. Final Prospectus and the Disclosure Package or any Issuer Free Writing Prospectus: (i) the names of the Underwriters, (ii) the sentences related to concessions, discounts and reallowances and (iii) the paragraphs related to price stabilization and short positions.

(c) Promptly after receipt by an indemnified party under this Section 8 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 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than under subsection (a) or (b) 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 reasonably 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. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, 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 party is an actual or potential party to such claim or action) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, action, suit or proceeding 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.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, 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 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 Company on the one hand and by the Underwriters on the other from the offering of the Securities to which such Loss relates; provided, however, no Underwriter shall be

required to contribute any amount in excess of the total underwriting discounts and commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. If the allocation provided by the immediately preceding sentence is unavailable for any reason, 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 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. The relative benefits received by the Company on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters, in each case as set forth on the cover page of the Canadian Final Prospectus and the U.S. 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 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 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 (d), 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. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, affiliate, and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. 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 principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount 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 principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount 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 or the Company. In the event of a default by any Underwriter as set forth in this Section 9, 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 Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Stabilization. In connection with the offering of the Securities, and in compliance with applicable laws, the Underwriters (or persons acting on their behalf) may over-allot Securities or effect

transactions with a view to supporting the market price of the Securities at a level higher than that which might otherwise prevail. However, stabilization may not necessarily occur.

11. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time after the Execution Time and prior to such delivery and payment (i) trading in any of the Company’s securities shall have been the subject of a cease trade order by the ASC or suspended by the SEC, the New York Stock Exchange or the Toronto Stock Exchange, (ii) trading in securities generally on the New York Stock Exchange or the Toronto Stock Exchange shall have been suspended or limited or minimum prices shall have been established on either of such exchanges, (iii) any inquiry, action, suit, investigation or other proceeding, whether formal or informal, is instituted, announced or threatened or any order is made by any federal, provincial or other governmental authority in relation to the Company or any of the Company subsidiaries or any law or regulation is promulgated, changed or announced, which, in the sole opinion of an Underwriter, acting reasonably, operates to or is expected to prevent or materially restrict the distribution or trading of the Securities or any other securities of the Company, (iv) a banking moratorium shall have been declared either by Federal or New York State authorities, Canadian federal authorities or European Union authorities or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or Canada of a national emergency or war, or other calamity or crisis the effect of which on U.S., European Union or Canadian financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any U.S. Preliminary Prospectus or Canadian Preliminary Prospectus, the Canadian Final Prospectus (exclusive of any amendment or supplement thereto) and the U.S. Final Prospectus (exclusive of any amendment or supplement thereto).

12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its 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 or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

18. Waiver of Jury Trial. The Company hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. Judgment Currency. The obligation of the Company in respect of any sum due to any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first Business Day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.
