2. BUYER’S REPRESENTATIONS AND WARRANTIES. The Buyer represents and warrants to the Company and the Placement Agents (as defined herein), as of the date hereof and as of the applicable Closing Date, that:

(a) No Public Sale or Distribution. The Buyer is acquiring the Securities for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the Buyer does not agree to hold any of the Securities for any minimum or other specific term and reserves the right to convert the Notes at any time in accordance with the terms thereof and/or dispose of the Securities at any time in accordance with or pursuant to an effective registration statement under the Securities Act or an exemption from such registration and in compliance with applicable federal and state securities laws. The Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute or effect any distribution of any of the Securities (or any securities that are derivatives thereof). For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity, and any Governmental Authority or any department or agency thereof. Notwithstanding the foregoing, the Buyer agrees not to dispose of any of the Securities (other than the disposition of the Notes upon conversion into Conversion Shares) while they are subject to any hold period under applicable Canadian Securities Laws unless such disposal is in compliance with an exemption from the prospectus requirements of applicable Canadian Securities Laws.

(b) Accredited Investor Status. At the time the Buyer was offered the Securities, it was, and as of the date hereof and as of the applicable Closing Date is, an “accredited investor” as that term is defined in Rule 501(a) of Regulation D (“Regulation D”) as is promulgated by the United States Securities and Exchange Commission (the “SEC”) under the Securities Act.

Exemptions and has entered into this Agreement as principal. The Buyer is an “accredited investor” in reliance on paragraph (m) of the definition of “accredited investor” in Section 1.1 of NI 45-106 and was not created or used solely to purchase or hold securities as an accredited investor under that paragraph (m). The Buyer is not an “insider” of the Company or a “registrant” (each as defined under applicable Canadian Securities Laws).

(d) Reliance on Exemptions. As of the applicable Closing Date, the Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the Securities.

(e) Exempt Offering. As of the applicable Closing Date, the Buyer has not taken any action that would cause the loss of any exemption from registration under the Securities Act applicable to the issuance of the Notes or the Common Shares issuable upon conversion of the Notes.

(f) No Governmental Review. The Buyer understands that no United States or Canadian federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(g) Purchase for Investment. As of the applicable Closing Date, the Buyer understands that, except as provided in the Registration Rights Agreement and in the terms of the Notes: (i) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) the Buyer shall have delivered to the Company an opinion of counsel, in a form reasonably satisfactory to the Company, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, (C) the Buyer provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the Securities Act, as amended (or a successor rule thereto) (“Rule 144” and “Rule 144A”, respectively) or to an accredited investor in a private transaction exempt from the registration requirements of the Securities Act; (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder; or (D) such transaction relates solely to the conversion of the Notes into Conversion Shares, which the Company and the Buyer understand and agree will be exempt under Section 3(a)(9) of the Securities Act. Notwithstanding the foregoing, (A) the Securities may be pledged in connection with a bona fide margin account

or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and the Buyer shall not be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document (as defined in Section 3(b)), including, without limitation, this Section 2(g), for effecting a pledge of Securities and (B) the Securities may be transferred to Affiliates of the Buyer. The Buyer (1) has such knowledge and experience in financial and business matters and in investments of this type that it is capable of evaluating the merits and risks of its investment in the Securities and of making an informed investment decision and (2) (I) has performed such investigations it deems necessary in order to make an informed investment decision and (II) can bear the economic risk of (x) an investment in the Securities and (y) a total loss in respect of such investment. The Buyer has such knowledge and experience in business and financial matters so as to enable it to understand and evaluate the risks of and form an investment decision with respect to its investment in the Securities and to protect its own interest in connection with such investment.

The Buyer understands that the certificates or other instruments representing the Notes and the book-entry accounts maintained by the Company’s transfer agent representing the Conversion Shares, except as set forth below, in the Registration Rights Agreement or in the terms of the Notes, shall bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such certificates):

[NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE HAVE BEEN] [THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL SELECTED BY THE HOLDER AND REASONABLY ACCEPTABLE TO THE COMPANY, IN A FORM REASONABLY SATISFACTORY TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT [OR] [,] (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD (X) PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT AND THE SELLING HOLDER PROVIDES REASONABLE ASSURANCE THAT THE SECURITIES CAN BE SOLD PURSUANT TO SUCH RULE OR (Y) TO AN ACCREDITED INVESTOR IN A PRIVATE TRANSACTION EXEMPT FROM THE REGISTRATION REQUIREMENTS OF SAID ACT[; OR (III) SUCH TRANSACTION RELATES SOLELY TO THE CONVERSION OF THIS SECURITY IN ACCORDANCE WITH ITS TERMS]. NOTWITHSTANDING THE FOREGOING, THE

SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

The Company shall instruct its transfer agent to remove (and shall cooperate with the transfer agent with respect to the removal of) the legend set forth above and the Company shall issue to the holder of such Securities by electronic delivery at, (x) in the case of Conversion Shares, the applicable balance account at DTC (as directed by the holder of such Securities), or (y) in the case of Notes, if eligible and requested by the holder, the applicable balance account at DTC, or otherwise, on the books of the Company or its transfer agent, if in the case of each of (x) and (y), (i) such Securities are sold or otherwise transferred pursuant to an effective registration statement under the Securities Act and in accordance with the plan of distribution contained therein, or (ii) a registration statement covering the resale of the Securities is effective under the Securities Act, or (iii) in connection with a sale, assignment or other transfer, such holder provides the Company with an opinion of counsel reasonably acceptable to the Company, to the effect that such sale, assignment or transfer of the Securities may be made without registration under the requirements of applicable securities laws, including the Securities Act, or (iv) are being sold or transferred pursuant to Rule 144, or (v) the Securities can be sold, assigned or transferred pursuant to Rule 144 without restrictions and without the requirement that the Company has complied with the public reporting requirements of the Exchange Act (and such holder provides the Company with a customary Rule 144 non-affiliate representation letter in connection therewith). The Company shall use its commercially reasonable efforts to cause its transfer agent to remove the legend set forth above in connection with such sale, assignment or other transfer promptly following satisfaction of one or more of the foregoing conditions and, in the case of clauses (i), (iii) and (iv) only, following the date on which it receives a written request from such holder to remove such legend, provided that, in the case of clauses (ii), (iii) and (iv) only, the Company, its transfer agent and such counsel shall have received a letter of representations and/or “will comply” letters in reasonably acceptable form from such holder and such other documentation and evidence as may be reasonably required by the Company or its transfer agent. If any Securities covered by a registration statement had been originally issued or delivered to the Investors with a U.S. restrictive legend thereon, then the Company shall, as soon as reasonably practicable following the effective date of such registration statement, remove, or cause its transfer agent to remove, all such legends and deposit such Securities in the appropriate account balance account at DTC. The Company shall be responsible for the fees of its transfer agent and all DTC fees associated with such issuance.

(i) OID Legend. The Buyer understands that if any Note is issued with more than de minimis original issue discount for U.S. federal income tax purposes, such Note shall bear the following additional legend on the face thereof:

THIS NOTE IS BEING ISSUED WITH ORIGINAL ISSUE DISCOUNT FOR UNITED STATES FEDERAL INCOME TAX PURPOSES. FOR INFORMATION REGARDING THE ISSUE PRICE, THE TOTAL AMOUNT OF ORIGINAL ISSUE DISCOUNT, THE ISSUE DATE, AND THE YIELD TO MATURITY OF THIS NOTE, PLEASE CONTACT THE GENERAL COUNSEL OF THE COMPANY AT THE

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY AND ANY SECURITY ISSUED ON CONVERSION HEREOF MUST NOT TRADE THE SECURITY BEFORE [the date which is four months and one day after the Initial Closing Date or Delayed Closing Date, as applicable, will be inserted].

The Buyer understands that if the Conversion Shares underlying the Initial Notes are issued before the date which is four months and one day after the Initial Closing Date, or if the Conversion Shares underlying the Delayed Note are issued before the date which is four months and one day after the Delayed Closing Date, the certificates or other instruments representing the Conversion Shares, except as set forth below, shall bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such certificates), as applicable:

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [the date which is four months and one day after the Initial Closing Date or Delayed Closing Date, as applicable, will be inserted].

THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR DRS ADVICE ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, THE SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE OR DRS ADVICE REPRESENTING SUCH SECURITIES IS NOT “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON TSX

The Placement Agents shall have no liability or obligation on or with respect to the accuracy or completeness, as of any date, of any information set forth in, or any omission from, any valuation or other materials that may have been provided or made available to the Buyer in connection with the Agreement. The Placement Agents shall have no liability to the Buyer with respect to any action heretofore or hereafter taken or omitted to be taken by the Buyer in connection with the Agreement.

(r) No Other Representations or Warranties. The Buyer acknowledges and agrees (i) that the representations and warranties of the Company in Section 3, in any certificate delivered pursuant to this Agreement and in any of the other Transaction Documents constitute the sole and exclusive representations and warranties of the Company in connection with the transactions contemplated by the Transaction Documents (and notwithstanding any information conveyed at management presentations, in virtual data rooms or in due diligence sessions and, without limiting the foregoing, any estimates, projections, predictions or other forward-looking information, or information relating to the quality, quantity or condition of the properties (whether real, personal or mixed) or assets of the Company or any of its Subsidiaries), (ii) there are uncertainties inherent in attempting to make estimates, projections, forecasts, plans, budgets and similar materials and information, the Buyer is familiar with such uncertainties, the Buyer is taking full responsibility for making their own evaluations of the adequacy and accuracy of any and all estimates, projections, forecasts, plans, budgets and other materials or information that may have been delivered or made available to it or any of its representatives and the Buyer has not relied or will not rely on such information, and any representations and warranties of any kind or nature expressed or implied in respect of such information is specifically disclaimed by the Buyer, and (iii) neither the Company nor any of its Affiliates shall have any liability to the Buyer or its Affiliates resulting from the Company’s reliance on any such information other than the representations and warranties of the Company in Section 3, in any certificate delivered pursuant to this Agreement and in any of the other Transaction Documents.

No proceeding has been instituted or, to the knowledge of the Company, threatened in any such jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification, licensing or registration. The Company has no Subsidiaries except as set forth in Schedule 3(a).

(i) by the mutual written consent of the Company and the Buyer;

(ii) by either the Company or the Buyer if the Initial Closing has not occurred on or prior to the date that is twenty (20) Business Days from the date hereof (the “Termination Date”); provided that the right to terminate this Agreement under this Section 8(a)(ii) shall not be available to any party if any breach by such party of its representations and warranties set forth in this Agreement or the failure of such party to perform any of its obligations under this Agreement has been a principal cause of or primarily resulted in the events specified in this Section 8(a);

(iii) by either the Company or the Buyer if any temporary or permanent order, judgment, injunction, ruling, writ or decree of any Governmental Authority shall have been enacted, promulgated, issued, entered, amended or enforced by any Governmental Authority or if any proceeding brought by a Governmental Authority seeking any of the foregoing shall be pending, or any applicable law shall be in effect enjoining or otherwise

prohibiting consummation of the transactions contemplated hereby, and shall have become final and non-appealable prior to the applicable Closing Date;

(iv) by the Buyer, if the Company shall have breached any of its representations or warranties or failed to perform any of its covenants or agreements set forth in this Agreement, which breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 6(e) and (B) is incapable of being cured prior to the Termination Date; and

(v) by the Company if the Buyer shall have breached any of its representations or warranties or failed to perform any of its covenants or agreements set forth in this Agreement, which breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 5(c) and (B) is incapable of being cured prior to the Termination Date.

(b) Any termination of this Agreement as provided in Section 8(a) shall be effective upon delivery of written notice thereof (i) by the Company to the Buyer or (ii) by the Buyer to the Company, as applicable, specifying the provision hereof pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than this Section 8(b) and Section 9), all of which shall survive termination of this Agreement, and there shall be no liability on the part of the Buyer or the Company in connection with this Agreement, except that no such termination shall relieve any party hereto from liability for damages to another party resulting from a Willful Breach of any representation, warranty, covenant or agreement in this Agreement prior to the date of termination or from Fraud. A “Willful Breach” means, with respect to any Person, a material breach or failure to perform that is the consequence of an act or omission of such party with the knowledge that such act or omission would, or would be reasonably expected to, cause a material breach of this Agreement. Notwithstanding anything herein to the contrary, if this Agreement is terminated pursuant to this Section 8, the Company shall remain obligated to reimburse the Buyer or its designee(s), as applicable, for the expenses described in Section 4(e).

9. MISCELLANEOUS.

(a) Governing Law; Jurisdiction; Jury Trial. This Note shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Agreement shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in New York, New York, Borough of Manhattan and any appellate court thereof, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address set forth in Section 9(f) of this Agreement and agrees that such service

shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude each party from bringing suit or taking other legal action against each party in any other jurisdiction to collect on such party’s obligations to the other, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of such party. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(b) Counterparts. This Agreement may be executed in identical counterparts, each of which shall be deemed an original but all of which shall constitute one and the same agreement. This Agreement, once executed by a party, may be delivered to the other party hereto by email transmission of a copy of this Agreement bearing the signature of the party so delivering this Agreement. Counterparts may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

(c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

(d) Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

(e) Entire Agreement; Amendments. This Agreement and the other Transaction Documents supersede all other prior oral or written agreements between the Buyer, the Company, their Affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the other Transaction Documents and the instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor the Buyer make any representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument in writing signed by the Company and the Required Holders, and any amendment to this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on the Buyer and holders of Securities and the Company. No provisions hereto may be waived other than by an instrument in

writing signed by the party against whom enforcement is sought. No such amendment shall be effective to the extent that it applies to less than all of the holders of the applicable Securities then outstanding. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties to the Transaction Documents, holders of Notes, as the case may be. The Company has not, directly or indirectly, made any agreements with the Buyer relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms that, except as set forth in this Agreement, the Buyer has not made any commitment or promise or has any other obligation to provide any financing to the Company or otherwise. As used herein, “Required Holders” means (I) prior to the Initial Closing Date, the Buyer and (II) on or after the Initial Closing Date, holders of a majority of the outstanding Principal amount of the Notes (calculated as of the date of the applicable amendment, waiver, consent or modification), which shall include Buyer so long as the Buyer or any of its Affiliates holds at least 25% of the outstanding Securities at such time.

(f) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement or any of the other Transaction Documents must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon delivery, when sent by electronic mail (provided that the sending party does not receive an automated rejection notice); or (iii) one (1) Business Day after deposit with an overnight courier service, in each case properly addressed to the party to receive the same.

(g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Notes. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required Holders, including by way of a Change of Control (unless the Company is in compliance with the applicable provisions governing Change of Control set forth in the Notes). The Buyer may assign some or all of its rights hereunder, other than to a Competitor or Disqualified Institution (each as defined in the Registration Rights Agreement) unless an Event of Default has occurred and is continuing at the time of such assignment, without the consent of the Company; provided such assignee agrees in writing to be bound by the

provisions hereof that apply to the Buyer, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights; provided, further, that no rights or obligations applicable to the Delayed Notes hereunder shall be assignable by the Buyer (other than to its Affiliates or if there is an event of default or default under the Notes by the Company and such event of default or default is continuing) until the Delayed Closing has occurred. The Buyer may provide to any potential assignee or transferee of this Agreement or any other Transaction Documents such information, including confidential information, concerning this Agreement, the other Transaction Documents and the financial position and the operations of the Company as, in the reasonable opinion of the Buyer, may be relevant or useful in connection with this Agreement, the other Transaction Documents or any portion thereof proposed to be acquired by such assignee or transferee, provided that each recipient of such information agrees with the Buyer to follow the same confidentiality restrictions applicable to the Buyer at such time. In connection with any potential assignment of this Agreement or the other Transaction Documents, the Company agrees to enter into such documents as may reasonably be required by the Buyer or its assignee to evidence such assignment and shall reasonably cooperate, at the Buyer or the potential assignee’s expense, with facilitating reasonable information requests in connection with such assignment.

(h) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Indemnitee (as defined below) shall have the right to enforce the obligations of the Company with respect to Section 9(k) and except that the Placement Agents are the intended third-party beneficiary of Sections 2 and 3 hereof and shall be permitted to rely on the legal opinions identified in Sections 6(b) and 6(c) hereof. The parties further agree that the Placement Agents may rely on the certificates and other deliverables to be delivered pursuant to this Agreement.

(i) Survival. The applicable representations and warranties of the Buyer and the Company contained in Sections 2 and 3 shall survive the Initial Closing and the Delayed Closing, respectively, and the agreements and covenants set forth in Sections 4 and 9 which by their terms are required to be performed after the applicable Closing shall, in each case, survive such Closing(s) until the Notes are fully repaid or converted in accordance with their terms.

(j) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

(k) Indemnification.

(i) Indemnity. The Company shall defend, protect, indemnify and hold harmless the Buyer, its Affiliates, directors, officers, partners, members and employees, and each Person, if any, who controls the Buyer or its Affiliates within the meaning of the Securities Act or the Exchange Act (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims (including causes of action, suits or claims asserted directly by or between an Indemnitee

and the Company), losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable and documented attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (A) any breach of any representation or warranty made by the Company in Section 3, or any other certificate, instrument or document contemplated by this Agreement, (B) any breach of any covenant, agreement or obligation of the Company contained in this Agreement or any of the other Transaction Documents, (C) the application by the Company of the proceeds of the Notes, or (D) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby that are actually incurred (unless such cause of action, suit or claim is based upon a material breach of an Indemnitee’s representations or warranties, or any failure of an Indemnitee or its Affiliates to perform or comply, in any material respect, with any of its covenants or agreements, in this Agreement or in any other Transaction Documents, or any violations by an Indemnitee or its Affiliates of state or federal securities or other laws or regulations, or any conduct by such Indemnitee or its Affiliate which constitutes bad faith, fraud, gross negligence or willful misconduct). The Buyer shall defend, protect, indemnify and hold harmless the Company and its Affiliates, directors, officers, partners, members and employees and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Company Indemnitees”) from and against any and all actions, causes of action, suits, claims (including causes of action, suits or claims asserted directly by or between a Company Indemnitee and the Buyer), losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Company Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable and documented attorneys’ fees and disbursements (the “Company Indemnified Liabilities”), incurred by any Company Indemnitee as a result of, or arising out of, or relating to (A) any breach of any representation or warranty made by the Buyer in Section 2, or any other certificate, instrument or document contemplated by this Agreement or (B) any breach of any covenant, agreement or obligation of the Buyer contained in this Agreement.

Without limiting the foregoing, the Company shall defend, protect, indemnify and hold harmless the Indemnitees from and against any and all Indemnified Liabilities which may be asserted against or incurred by such Indemnitees under or on account of any applicable Environmental Laws (including the assertion of any Liens thereunder), whether as a lender to the Company, or as successor to or assignee of any right or interest of any Group Member or as a result of any order, investigation or action by any Governmental Authority relating to any one of their business or property in which it has a direct or indirect interest (the

“Environmental Indemnified Liabilities”). Environmental Indemnified Liabilities shall include, but not be limited to, any Indemnified Liabilities arising from:

unless such cause of action, suit or claim is based upon a material breach of an Indemnitee’s representations or warranties, or any failure of an Indemnitee or its Affiliates to perform or comply, in any material respect, with any of its covenants or agreements, in this Agreement or in any other Transaction Documents, or any violations by an Indemnitee or its Affiliates of state or federal securities or other laws or regulations, or any conduct by such Indemnitee or its Affiliate which constitutes bad faith, fraud, gross negligence or willful misconduct.

Any indemnification payment made pursuant to this Agreement shall be treated as an adjustment to purchase price for Tax purposes, except as otherwise required by law or deemed impermissible under IFRS or U.S. GAAP, as applicable. Such payment shall not result in an adjustment to the value of the original investment reported by the Company under IFRS or U.S. GAAP, as applicable.

(ii) Third Party Claims. Promptly after receipt by any Indemnitee or Company Indemnitee (in either case, an “Indemnified Party”) of notice of any demand, claim, or circumstances from a third party which would or might give rise to a claim or the commencement of any action in respect of which indemnity may be sought pursuant to Section 9(k)(i) (a “Third Party Claim”), such Indemnified Party shall promptly notify the Buyer or the Company (as applicable, the “Indemnifying Party”) in writing describing such Indemnified Liabilities or Company Indemnified Liabilities, as applicable (the “Indemnified Loss”), including the amount thereof, if known, in such detail as is reasonably practicable and the Indemnifying Party shall have sixty (60) calendar days after receipt of such notice to notify the Indemnified Party that it elects to assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is actually and materially and adversely prejudiced by such failure to notify. In any such action, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (I) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, (II) the Indemnifying Party shall have failed to assume the defense of such action within such sixty (60) calendar day period, or (III) in the reasonable judgment of counsel to such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Indemnifying Party shall not be liable for any settlement of any action effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of the Indemnified Party, the Indemnifying Party shall not affect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such action and such settlement shall not include any admission as to fault on the part of the Indemnified Party. For the avoidance of doubt, the obligations of the Indemnitees and Company Indemnitees contained in this Section 9(k)(ii) shall apply to Third Party Claims only, and shall not apply to direct claims by or between an Indemnitee and the Company.

(iii) Limitations.

(A) Except in the case of Fraud or Willful Breach and in respect of Environmental Indemnified Liabilities, notwithstanding anything to the contrary, (x) the maximum aggregate liability of the Company for all Indemnified Losses under Section 9(k)(i) (other than in respect of Indemnified Losses relating to Environmental Indemnified Liabilities) shall be an amount equal to [***]% of the amount that has been actually funded by the Buyer on the Initial Closing Date (provided, that, such amount is to be increased to account for the amount that has been actually funded by the Buyer as of the Delayed Closing Date if the Delayed Closing Date has occurred) and (y) the maximum aggregate liability of the Buyer for all Indemnified Losses under Section 9(k)(i) shall be not exceed an amount equal to [***]% of the sum of the principal amount of the Notes that remains outstanding at the time of the notice of a claim brought under Section 9(k)(i) plus accrued and unpaid interest thereon.

(B) Prior to and in conjunction with seeking indemnification, an Indemnified Party shall use its commercially reasonable efforts to mitigate the amount of Indemnified Losses for which it may be entitled to indemnification hereunder.

(C) Except in the case of criminal activity, Fraud or Willful Breach, the right of the Indemnitees to be indemnified pursuant to this Section 9(k) will be the sole and exclusive remedy of the Indemnitees with respect to all monetary losses in connection with, arising out of, or resulting from the subject matter of this Agreement. Notwithstanding any other provision of this Agreement, no party hereto shall be liable for any exemplary or punitive damages or any other damages to the extent not reasonably foreseeable arising out of or in connection with this Agreement or the transactions contemplated hereby (in each case, unless any such damages are awarded pursuant to a third party claim). Notwithstanding the foregoing, nothing in this Section 9(k) will limit any party’s right to seek and obtain specific performance or injunctive relief to which any party may be entitled or limit or diminish the rights of the applicable Indemnitees to indemnification under the Production Payment Agreement pursuant to the indemnification provisions contained therein.

(l) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m) Remedies. Each party to this Agreement shall be entitled to enforce all rights provided herein specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the parties recognize that in the event that any party fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the non-breaching parties. The parties therefore agrees that the non-breaching parties shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security.

(n) Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyer hereunder or pursuant to any of the other Transaction Documents or the Buyer enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, foreign, state, local or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.
