If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable and documented fees and expenses of such proceeding and shall pay the reasonable and documented fees and expenses of such counsel related to such proceeding, as incurred.

It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by RBC Capital Markets, LLC, and any such separate firm for the Company, the Guarantors, their respective affiliates, directors and officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for the reasonable and documented fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such

settlement is entered into more than 60 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request or contested such reimbursement in good faith prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, liabilities or expenses referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding

the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of an untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 (f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) the Company shall have failed, refused or been unable to perform any agreement on its part to be performed under this Agreement when and as required; (ii) any other condition to the obligations of the Initial Purchasers under this Agreement to be fulfilled by the Company and each of the Guarantors pursuant to Section 7 is not fulfilled when and as required in any material respect; (iii) trading in any securities of the Company shall be suspended or limited by the Ontario Securities Commission, any other Canadian securities regulator whose jurisdiction the Company is subject to, the Toronto Stock Exchange, OTCQX, or the Commission; (iv) trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or materially limited, or minimum prices shall have been established thereon by the Commission, FINRA, or by such exchange or other regulatory body or governmental authority having jurisdiction; (v) a general moratorium shall have been declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; (vi) there is an outbreak or escalation of hostilities or national or international calamity or crisis in any case involving the United States, on or after the date of this Agreement, or if there has been a declaration by the United States of a national emergency or war or other national or international calamity or crisis (economic, political, financial or otherwise) which affects the U.S. and international financial markets, that, in the judgment of the Representative (acting reasonably), is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum; or (vii) there shall have been such a material adverse change in general economic, political or financial conditions or the effect (or potential effect if the financial markets in the United States or Canada have not yet opened) of international conditions on the financial markets in the United States or Canada shall be such that, in the judgment of the Representative (acting reasonably), makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

9. Defaulting Initial Purchaser.

(a) If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 48 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 48 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers and the Company and the Guarantors. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 hereof (except for any such expenses of a defaulting Initial Purchaser) and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company, the Guarantors or any non-defaulting Initial Purchaser for damages caused by its default.

10. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all reasonable costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the reasonable fees and expenses of the Company’s and the Guarantors’ counsel (including local and special counsel) and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related, reasonable and documented fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors including, without limitation, expenses associated with the preparation or dissemination of any electronic road show presentation, expenses associated with production of road show slides and graphics, and, with the prior written approval of the Company, reasonable and documented fees and expenses of any consultants engaged in connection with the road show presentations, and travel and lodging expenses of the representatives and officers of the Company and any such consultants.

(b) If (i) this Agreement is terminated pursuant to Section 8, (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers (other than pursuant to Section 9) or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and each of the Guarantors jointly and severally agrees to reimburse the Initial Purchasers for all reasonable and documented out- of-pocket costs and expenses (including the reasonable and documented fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby subject to [REDACTED]

No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Guarantors or the Initial Purchasers.

(d) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(e) Submission to Jurisdiction; Waiver of Jury Trial. The Company agrees that any suit, action or proceeding against the Company brought by any Initial Purchaser, the directors, officers, employees and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. The Issuers hereby waive all right to trial by jury in any proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Issuers agree that a final judgment in any such proceeding brought in any such court shall be conclusive and binding upon the Issuers and may be enforced in any other courts in the jurisdiction of which the Issuers are or may be subject, by suit upon such judgment.

(f) Waiver of Immunity. With respect to any proceeding related to this Agreement or the transactions contemplated hereby, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, and with respect to any suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any such proceeding brought in any such court, each party waives any such immunity in any such court or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such proceeding or enforcement of a judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended. Each Issuer hereby designates, appoints and empowers CT Corporation System, 00 Xxxxxx Xxxxxx, Xxx Xxxx, XX (and any successor thereto, the “Agent of Service”) as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and its properties, assets and revenues, service of any and all legal process, summons, notices and documents that may be served in any action, suits or proceedings brought against it in any courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York with respect to any proceeding related to this Agreement or the transactions contemplated hereby. Each Issuer further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents that may be served in any action, suits or proceedings brought against it by serving a copy thereof upon the Agent of Service. The Issuers agree that the failure of the Agent of Service to give any notice of such service to them shall not impair

or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon.

(g) Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers could purchase U.S. dollars with such other currency in the City of New York on the business day preceding that on which final judgment is given. The obligations of the Issuers in respect of any sum due from them to the Initial Purchasers shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by the Initial Purchasers of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Initial Purchasers may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to the Initial Purchasers hereunder, the Issuers agree, as a separate obligation and notwithstanding any such judgment, to indemnify the Initial Purchasers against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Initial Purchasers hereunder, the Initial Purchasers agree to pay to the Issuers (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to the Initial Purchasers hereunder.

(i) Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.
