Except in the case of fraud, no Party shall be liable to any other Party, nor any successor in interest or beneficiary or assignee of this Agreement, for any consequential, incidental, indirect, special or punitive damages arising out of this Agreement or any breach thereof (it being understood that amounts owing or alleged to be owing by a Person to a Third Party on account of Claims by Third Parties constitute actual damages to that Person regardless of whether the Third Party’s Claim for that amount includes consequential, incidental, indirect, special or punitive damages); provided that consequential, incidental, indirect, special or punitive damages shall not include direct financial loss suffered by a Party or an Indemnified Party, including diminution of value and loss of profits, and direct financial loss and loss of profits shall be recoverable except where restricted by principles of remoteness under Applicable Law. In the case of fraud, the limitations on indemnification (including as to duration and amount) set forth in Sections 5.3 and 5.4 shall not apply to any claim for indemnification pursuant to this Article 5.

5.6 | Third Party Claim Indemnity Procedures

| (a) | In the event that any written Claim for which an Indemnifying Party may have liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a Third Party (a “Third Party Claim”), such Indemnified Party shall promptly, but in no event more than ten (10) Business Days following such Indemnified Party’s receipt of a Third Party Claim, notify the Indemnifying Parties in writing of such Third Party Claim, the amount or the estimated amount of damages sought thereunder to the extent then reasonably ascertainable (which estimate shall not be conclusive of the final amount of such Third Party Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”). However, the failure to give prompt notice will not affect the rights or obligations of the Indemnifying Party except and only to the extent that, as a result of such failure, the Indemnifying Party was prejudiced by such failure. The

​

23

Indemnifying Party shall have ten (10) Business Days (or such lesser number of days set forth in the Claim Notice as may be required by court proceedings in the event of a litigated matter) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third Party Claim, and if such notification is not provided, it shall be deemed to have elected not to defend the Indemnified Party in respect of the Third Party Claim.

| (b) | In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the power to direct and control such defence at its expense; provided that the Indemnified Party will have the right to approve defence counsel, which approval will not be unreasonably withheld. Once the Indemnifying Party has duly assumed the defence of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defence and to employ a single separate counsel of its choosing for this purpose; provided that the cost of such counsel shall be at its expense, unless the Indemnified Party shall have reasonably concluded, based on the advice of outside counsel, that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case the Indemnified Party may participate in such defence and employ separate counsel at the Indemnifying Party’s expense; and provided further that provided that the power to control an direct such defence shall remain with the Indemnifying Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third Party Claim if such settlement (i) does not include an unconditional written release by the claimant or plaintiff of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) would result in (A) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any Person related thereto; or (B) a finding or admission of a violation of Applicable Law, wrongdoing or violation of the rights of any Person by the Indemnified Party or any Person related thereto.

| (c) | In the event that the Indemnified Party shall in good faith determine (i) that the conduct of the defense of any action, proceeding or claim subject to indemnification hereunder or any proposed settlement of any such action, proceeding or claim by the Indemnifying Party could reasonably be expected to (A) affect adversely the Indemnified Party’s tax liability or the ability of any Affiliate of the Indemnified Party who is a party to this Agreement to conduct its business or (B) be inconsistent with the position of the Indemnified Party with respect to its taxation status in any jurisdiction (including without limitation whether it should file any tax return), or (ii) that the Indemnified Party may have available to it one or more defenses or counterclaims that are in addition to, or inconsistent with, one or more of those that may be available to the Indemnifying Party in respect of such action, proceeding or claim or any litigation relating thereto, the Indemnified Party shall have the right at all times to take over and assume control over the defense, settlement, negotiations or litigation relating to any such action, proceeding or claim at the sole cost of the Indemnifying Party, provided, that, the Indemnified Party shall not settle any such action, proceeding or claim without the written consent of the Indemnifying Party.

| (d) | If the Indemnifying Party elects not to, or is deemed to elect not to, defend the Indemnified Party against a Third Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, the Indemnified Party shall have the right, but not the obligation, to assume its own defence, it being understood that the Indemnified

​

24

Party’s right to indemnification for a Third Party Claim shall not be adversely affected by assuming the defence of such Third Party Claim. The Indemnified Party (i) may defend such Third Party Claim and (ii) may not enter into a settlement thereof without obtaining approval of the Indemnifying Party (which approval shall not be unreasonably withheld, delayed or conditioned) unless the Indemnified Party will not be seeking indemnification from the Indemnifying Party for any amounts paid pursuant to such settlement thereof or for any other consequences of such Third Party Claim.

| (e) | The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defence of a Third Party Claim, including by providing access to each other’s relevant business records and other documents and employees. Further, the applicable Party conducting the defence of a Third Party Claim shall keep the other Party apprised of material developments from time to time.

| (f) | The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of confidential information (consistent with Applicable Law) and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable solicitor-client or litigation privileges. For the avoidance of doubt, nothing in this Section shall be construed as a waiver by an Indemnified Party or an Indemnifying Party of any privilege, including any privilege associated with separate counsel as described herein.

5.7 | Adjustment to Purchase Price

| (a) | All amounts payable by the McEwen Parties to the Purchaser Indemnified Parties pursuant to Section 5.1 will be deemed to be a decrease to the Purchase Price. All amounts payable by Purchaser to the McEwen Indemnified Parties pursuant to Section 5.2 will be deemed to be an increase to the Purchase Price.

6.2 | Amendment

This Agreement may only be amended by the written agreement of all the Parties hereto or, as applicable, their successors and permitted assigns.

6.3 | Public Disclosure

A Party shall not issue any press release or make any other public statement or disclosure with respect to this Agreement without the consent of the other Parties (which consent shall not be unreasonably withheld, conditioned or delayed); provided, however, that the foregoing shall be subject to each Party’s overriding obligation to make any disclosure or filing in accordance with Applicable Laws, including applicable securities laws, and if, in its reasonable opinion, such disclosure or filing is required and the other Party has not reviewed or commented on the disclosure or filing, the Party shall use its reasonable best efforts to give the other Party prior oral or written notice and a reasonable opportunity to review or

​

26

comment on the disclosure or filing (other than with respect to confidential information contained in such disclosure or filing). The Party making such disclosure shall give reasonable consideration to any comments made by the other Party or its counsel, and if such prior notice is not possible, shall give such notice immediately following the making of such disclosure or filing.

6.4 | Assignment

No Party may assign or transfer any right, benefit, interest or obligation in or under this Agreement without the prior express written consent of the other Parties, which consent may not be unreasonably withheld; provided that in the case of any assignment or transfer, the assigning or transferring Party shall remain liable for all of its obligations hereunder, including indemnity obligations.

6.5 | Governing Law

This Agreement and all matters related hereto or arising herefrom are governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein. Each of the Parties irrevocably attorns to the exclusive jurisdiction of the courts of the Province of Ontario in all matters related to, or arising from, this Agreement.

6.6 | Waiver

| (a) | No failure on the part of a Party to exercise, no delay in exercising, and no course of dealing with respect to, any right, power or privilege established by this Agreement shall operate as a waiver thereof.

| (b) | Except as otherwise expressly provided for herein, no waiver of any provision of this Agreement or consent to any departure by any Party from any provision of this Agreement shall be effective unless it is confirmed in writing. The waiver or consent shall be effective only in the specific instance, for the specific purpose and for the specific length of time for which it is given.

| (c) | The single or partial exercise of any right, power or privilege established by this Agreement shall not preclude any other exercise thereof.

6.7 | Severability

Each of the provisions contained in this Agreement is distinct and severable and a declaration of invalidity or unenforceability of any such provision or part thereof by a court of competent jurisdiction in any jurisdiction shall not affect the validity or enforceability of that provision in any other jurisdiction, or affect the validity or enforceability of any other provision hereof. To the extent permitted by Applicable Laws, the parties waive any provision of law which renders any provision of this Agreement invalid or unenforceable in any respect. The Parties shall engage in good faith negotiations to replace any provision which is declared invalid or unenforceable with a valid and enforceable provision, the economic effect of which comes as close as possible to that of the invalid or unenforceable provision which it replaces.

6.8 | Benefit of the Agreement

This Agreement shall enure to the benefit of and be binding upon the Parties hereto and their respective successors and permitted assigns, provided that any transfer of or any Encumbrance upon any rights under this Agreement not made in accordance with this Agreement shall be null and void and of no force or effect.

​

27

6.11 | Further Assurances

Each of the Parties shall promptly do, make, execute or deliver, or cause to be done, made, executed or delivered, all such further acts, documents and things as any other Party hereto may reasonably require from time to time in order to give full effect to the provisions of this Agreement and shall use reasonable efforts and take all such steps as may be reasonably within its power to implement to their full extent the provisions of this Agreement.
