		(a)	Power and Capacity: it has full power and capacity to enter into this Agreement and to do
all acts and things and execute and deliver all documents as are required hereunder to be done, observed, performed or executed

thereof.



 


		4.	Participation by the Investor in Equity Financing



 


Subject to compliance with Applicable
Law, including, if required, the approval of the Exchange, from and after the date of this Agreement and for so long as the Investor’s
Percentage is at least 10%, the Investor shall have the following rights in respect of any Equity Financing:


 




     


     


    

 


		(a)	the right, but not the obligation, to participate, in such Equity Financing up to the extent required
to allow the Investor to maintain the same Investor’s Percentage that it possessed immediately prior to the announcement
of such Equity Financing such that, if fully exercised, the Investor does not suffer any equity dilution (the “Participation
Right”); and



 


		(b)	the right, but not the obligation, to subscribe for any Equity Securities issued in connection
with such Equity Financing not taken up by other investors or subscribers to enable the Investor to increase its equity ownership
percentage in the Company (the “Top-up Right”).



 


If the Company intends or proposes to, or enters into
documentation purporting to issue or authorize an Equity Financing, then in each case:


 


		(i)	Notice of Financing: the Company shall first provide written notice of such Equity Financing
to the Investor, as soon as possible, but in any event on or prior to the earlier of 10 Business Days prior to the expected completion
date of such Equity Financing, and the date on which the Company files a preliminary prospectus or other offering document in connection
with such Equity Financing, including a detailed summary of the material terms and conditions of such Equity Financing, together
with any other information that the Investor may thereafter reasonably request in respect of the same;



 


		(ii)	Election Right of Investor: if the Investor wishes
to exercise its Participation Right or Top-up Right, as the case may be, the Investor must provide the Company with written notice
that it is exercising its Participation Right or its Top-up Right, as the case may be, before the earlier of (A) five (5) Business
Days after the date of receipt by the Investor of notice of such Equity Financing from the Company pursuant to paragraph (i) above,
and (B) 48 hours after public announcement of such Equity Financing if such Equity Financing is a “bought deal” public
offering (or 24 hours in the event that the Investor elects to exercise its Top-up Right and such exercise would require shareholder
approval under Applicable Law); failing which, the Investor shall be deemed to have elected not to exercise its rights under this
paragraph 4;



 


		(iii)	Flow-Through Shares: to the extent that such Equity Financing involves the issuance of common
shares in the Company that will be issued as “flow-through shares” (as defined in subsection 66(15) of the Income
Tax Act (Canada)), at a price per share that reflects a premium associated with a flow-through designation, and the Investor
elects to participate in such offering, the Company agrees to negotiate in good faith the price at which such flow-through shares
will be issued to the Investor, taking into consideration that any benefits received by a purchaser of flow-through shares will
not be received by the Investor;



 


		(iv)	Completion of Equity Financing: if the Investor notifies the Company of its election to
exercise its Participation Right or Top-up Right pursuant to paragraph (ii) above, the Company shall use all commercially reasonable
efforts, including, but not limited to, promptly making all required filings with the Exchange or any other applicable securities
regulator, commission or authority and paying all fees in connection therewith, to obtain any Exchange or regulatory approvals
required in respect of the issuance of Equity Securities to the Investor in respect of such Equity Financing and, subject to Applicable
Law, the Company and the Investor shall proceed to complete the purchase and sale of the Equity Securities that are the subject
of such Equity Financing, which completion may take place concurrently with and subject to the closing of the issuance of other
Equity Securities forming part of the same Equity Financing, provided that the issue price offered to the Investor shall,
subject to Applicable Law, be equivalent to the issue price under the Equity Financing. In the case of an Equity Financing that
is a “bought deal” public offering, the Equity Securities that the Investor elects to purchase shall be issued to the
Investor by the Company in a concurrent private placement with the Investor on the same terms as such wider Equity Financing, subject
to Applicable Law;



 










     


     


    

 


		(v)	Prospectus Offering: without limitation to any of the rights of the Investors under paragraphs
(i) to (iv) above, the Company shall use commercially reasonable efforts to include the Investor’s pro rata entitlement in
any such Equity Financing that is a prospectus offering, provided that if the Investor’s pro rata share is not included in
such prospectus offering, the Company shall ensure that the Investor is provided with the opportunity to subscribe for such Equity
Securities on a private placement basis as soon as reasonably possible thereafter, and in no case later than fifteen (15) Business
Days after the closing of the prospectus offering on terms no less favourable as those provided to investors under such Equity
Financing. Notwithstanding the foregoing, any Equity Securities subscribed for by the Investor in the case of a public offering
that is a “bought deal” shall be issued on a private placement basis on terms no less favourable as those provided
to investors under such Equity Financing;



 


		(vi)	Shareholder Approval: if the Company is required
by the Exchange or otherwise to seek shareholder approval for the issuance of Equity Securities to the Investor under such Equity
Financing, then the Company may complete that portion of such Equity Financing that the Exchange will then permit without shareholder
approval, provided that the Investor subscribes for and is issued at that time the lesser of:





 


		(A)	a pro rata portion of the maximum number of Equity Securities that the Investor wishes to purchase
as part of such Equity Financing based on the size of the issuance that the Company is entitled to complete without obtaining shareholder
approval; and



 


		(B)	the maximum number of Equity Securities that the Exchange will permit the Company to issue to the
Investor as part of such Equity Financing without obtaining shareholder approval,



 


and the Company shall call and
hold a meeting of its shareholders to consider the subscription and issuance of the balance of the Equity Securities in such Equity
Financing as soon as reasonably practicable and in any event within sixty (60) days after the date that the Company is advised
that it will require shareholder approval. In connection with such meeting of shareholders (or any adjournment or postponement
thereof), unless inconsistent with the fiduciary duties of the Board, management of the Company shall recommend in writing that
shareholders vote in favour of such equity issuance to the Investor and shall vote their common shares in the Company in respect
of which management is granted a discretionary proxy in favour of such equity issuance to the Investor. If shareholder approval
for such issuance is obtained, the Company will issue to the Investor the remaining Equity Securities in such Equity Financing
on the Business Day following receipt of such shareholder approval. If, however, shareholder approval for the issuance of Equity
Securities in such Equity Financing is not obtained at such meeting, the Company shall not issue any such Equity Securities to
the Investor; and


 


		(vii)	Continuing Right of the Company: if the Investor
elects or is deemed to have elected not to exercise its Participation Right or Top-up Right in respect of such Equity Financing
then the Company may, at any time within forty-five (45) days of such election (or deemed election), complete such Equity Financing
on substantially the same terms and conditions as initially indicated to the Investor by the Company.



 




     


     


    

 


For greater certainty and notwithstanding
anything to the contrary contained in this Agreement, the participation rights of the Investor under this paragraph 4 or otherwise
will not apply to the issuance by the Company of Equity Securities (A) pursuant to the Company’s stock option plan or other
compensation plans for employees, consultants, officers or directors of the Company and its Affiliates (including the issuance
of options, restricted stock, restricted share units, restricted stock units, performance share units, deferred share units and
any securities issued on exercise, vesting or settlement thereof), (B) in respect of securities issued or made issuable in connection
with bona fide acquisitions by the Company, (C) the conversion or exchange of any Equity Securities of the Company into common
shares of the Company, or the exercise of any warrants or other rights to acquire common shares of the Company, or (D) in respect
of securities issued or made issuable pursuant to or in connection with a rights offering or similar transaction.


 


		5.	Participation by the Investor in Debt or Royalty Financing



 


If, at any time while the Investor’s
Percentage is at least 10%, the Company intends or proposes to issue any convertible debt securities, or enters into documentation
purporting to create, incur or assume any Indebtedness (as defined in the Credit Agreement or, if the Credit Agreement is of no
force and effect, as imported into this Agreement from the Credit Agreement with the same meaning as set out in the Credit Agreement
immediately prior to its termination), including in respect of any Project Financing, or establish, sell, or create any royalty,
metal stream or similar arrangement (in each case, other than Permitted Indebtedness (as defined in the Credit Agreement or, if
the Credit Agreement is of no force and effect, as imported into this Agreement from the Credit Agreement with the same meaning
as set out in the Credit Agreement immediately prior to its termination)) to any Person other than the Investor (any such transaction,
a “Debt or Royalty Financing”), then in each case:


 


		(a)	Notice of Financing: the Company shall promptly provide written notice of such Debt or Royalty
Financing, as the case may be, to the Investor, including a detailed summary of the material terms and conditions of such Debt
or Royalty Financing, together with any other information that the Investor may thereafter reasonably request in respect of the
same;



 


		(b)	Election Right of Investor: within twenty (20) Business Days of receipt of the notice of
the Company contemplated in paragraph (a) above, the Investor may notify the Company that it has elected to participate in such
Debt or Royalty Financing, up to an amount equal to the Investor’s Percentage in respect of such Debt or Royalty Financing
on a pro rata basis, at its sole discretion, and thereafter the Company and the Investor will (and, if applicable, the Company
will cause any other applicable Persons to) take steps to promptly complete such Debt or Royalty Financing on terms and conditions
acceptable to the Investor but which substantially match the terms of the Debt or Royalty Financing proposed to be entered into
by the Company with the other Person, if applicable; failing which, the Investor shall be deemed to have elected not to exercise
its rights under this paragraph 5; and



 


		(c)	Continuing Right of the Company: if the Investor does not elect (or is deemed to have not
elected) to exercise its right of participation pursuant to paragraph (b) above then the Company may, at any time within sixty
(60) days of such election (or such deemed election at the end of the above twenty (20) Business Day period), take steps to complete
such Debt or Royalty Financing on substantially the same terms and conditions as initially indicated to the Investor.

then-current Directors and officers) shall take all such actions and steps to promptly appoint the Investor Nominee(s) to the
Board, including convening a meeting of the shareholders or directors of the Company, as the case may be, in order to so effect
such nomination and appointment. The parties acknowledge that appointees to the Company’s Board (including the Investor
