ARTICLE 3

PARTICIPATION RIGHTS

3.1 Pre-emptive Right

(1) Unless a Trigger Event has occurred, if the Corporation proposes to issue or sell any New Securities (including pursuant to any exercise of pre-emptive or similar rights held by any other person) (a “New Securities Offering”), then Osisko has the right (the “Participation Right”) to subscribe for and purchase, each type, class or series of New Securities, as applicable, on terms and conditions not less favorable than those provided to the other subscribers of such New Securities in the New Securities Offering, up to an amount sufficient to maintain its aggregate pro rata ownership interest in the outstanding Shares (calculated on a Partially-Diluted Basis), immediately prior to the closing of the New Securities Offering. Osisko may exercise its Participation Right with respect to any underwritten New Securities Offering through a concurrent and separate Private Placement, in which case Osisko and the Corporation shall use commercially reasonable efforts to cause the announcement of such Private Placement to occur at the same time as the announcement of such New Securities Offering, being understood that the closing of any such Private Placement may take place after the closing of any such New Securities Offering as contemplated in Section 3.1(5).

(2) If the Corporation proposes to issue or sell New Securities pursuant to a New Securities Offering giving rise to the Participation Right, the Corporation will give written notice to Osisko (the “Offering Notice”) as soon as possible and, in any event, at least five (5) Business Days prior to the earlier of (i) the Corporation entering into a binding agreement with any person providing for such New Securities Offering, and (ii) the Corporation publicly announcing such New Securities Offering. The Offering Notice will contain the following information, to the extent known at the time:

a) the total number of each type, class and series of Equity Securities outstanding as at the date of the Offering Notice;

b) the total number of each type, class and series of New Securities to be offered in such New Securities Offering, and the rights, privileges, restrictions, terms and conditions of each such type, class and series;

c) the proposed price (on a per security basis) payable for the New Securities upon which Osisko is entitled to purchase pursuant to the Participation Right;

d) the maximum number of New Securities that Osisko is entitled to subscribe for;

e) the proposed announcement date, and the proposed closing date for such New Securities Offering; and

f) any other material terms of such New Securities Offering, including a statement as to the expected use of proceeds;

- 9 -

and the Corporation will use its commercially reasonable efforts to consult with Osisko and, if applicable, any stock exchange(s) on which the Corporation’s securities are listed as to the size, structure and other characteristics of the New Securities Offering with a view to giving full effect to the intention of the Parties that Osisko will be able to fully exercise its Participation Right in connection therewith. Further, any material information not provided to Osisko in the Offering Notice because it is not then known shall be provided forthwith upon becoming known to the Corporation. Notwithstanding any other provision of this Agreement to the contrary, in the case of a New Securities Offering that is implemented by way of Bought Deal offering, the Corporation shall provide notice to Osisko of such potential Bought Deal offering as soon as it is seriously considering such a Bought Deal offering or is in advanced discussions with underwriters in connection thereto, and the reference in this Section 3.1(2) to five (5) Business Days shall be changed to such notice as is practicable in the circumstances which shall at a minimum be thirty six (36) hours, provided that such minimum notice period may be waived in writing by any officer of Osisko irrespective of the notice provisions set forth herein.

(3) In the case of a contemplated issuance of securities for non-cash consideration, the Board shall determine the deemed issue price, acting reasonably, which shall be the price at which Osisko may participate.

(4) If Osisko wishes to exercise the Participation Right in respect of a particular New Securities Offering, Osisko shall give written notice to the Corporation (the “Participation Exercise Notice”) of the exercise of its Participation Right and of the number of each type, class and series of New Securities Osisko wishes to purchase (the “Participation Securities”), within four (4) Business Days after the date of receipt of the Offering Notice. Notwithstanding any other provisions of this Agreement to the contrary, in the case of a New Securities Offering that is implemented by way of a Bought Deal offering, Osisko shall use commercially reasonable efforts to provide its Participation Exercise Notice within twenty four (24) hours following the receipt of the Offering Notice so that the participation by Osisko can be announced concurrently with the Bought Deal, provided, however, that failure to do so shall not prevent Osisko from providing a Participation Exercise Notice within four (4) Business Days after the date of receipt of the Offering Notice and shall not prevent Osisko from exercising its Participation Right through a concurrent Private Placement as contemplated in Section 3.1(1).

(5) If Osisko exercises its Participation Right, subject to the receipt of any required regulatory approvals (including of any stock exchange(s) on which the Corporation’s securities are listed), which approvals the Corporation will use its commercially reasonable efforts to promptly obtain (including applying for any necessary price protection confirmations), the closing of the purchase by Osisko of its New Securities will occur on the date indicated by Osisko in the Participation Exercise Notice, but in any event not more than the later of (i) ten (10) Business Days following the Participation Exercise Notice and (ii) the closing of the sale of the New Securities to the other purchasers thereof.

(6) The Participation Right will not terminate if, on receipt of any Offering Notice from the Corporation, Osisko fails or declines to exercise it.

(7) If pursuant to the rules of any stock exchange(s) on which Shares are listed or applicable law, the exercise of the Participation Right by Osisko results in Osisko holding 20% or more of the voting shares of the Corporation or otherwise results in a requirement for the Corporation to obtain shareholder approval, Osisko may, at its discretion, accept such lesser amount of New Securities, as applicable, as will not result in Osisko holding 20% or more of the Corporation’s voting shares or otherwise trigger shareholder approval.

ARTICLE 4

PARTICIPATION RIGHT ON STREAMING AND SIMILAR RIGHTS

4.1 Right to Participate in the Purchase of Future Streams and Similar Transactions

(1) Unless a Trigger Event has occurred, Osisko shall have the right to participate in, and acquire up to 20% of, any stream, forward sale, prepay, royalty, off-take or similar transaction (each an “Eligible Transaction”) between the Corporation as purchaser and/or creditor and one or more third party counterparties (the “Stream Participation Right”). The Corporation agrees that the Stream Participation Right shall be exclusive to Osisko and neither it nor its Affiliates shall solicit, negotiate, entertain or agree any similar right or arrangement with any other Person whose primary business relates to: (i) mine exploration, development or operation; or (ii) the purchase and sale of metals streams, royalties or similar transactions.

(2) The Corporation shall provide Osisko written notice (the “Stream Offer Notice”) promptly and in any case, within two (2) Business Days of entering into a term sheet (whether binding or non-binding) or agreeing commercial terms in respect of an Eligible Transaction. The Stream Offer Notice shall inform Osisko of its Stream Participation Right and detail all relevant information pertaining to the Eligible Transaction to enable Osisko to determine if it wishes to exercise its Stream Participation Right.

(3) The Corporation shall inform the counterparty to the Eligible Transaction of Osisko’s Stream Participation Right and use commercially reasonable efforts to include Osisko within the scope of its confidentiality undertaking in respect of the Eligible Transaction or to have the counterparty agree to execute a separate confidentiality undertaking with Osisko, as applicable.

(4) Within fifteen (15) Business Days of receipt of a Stream Offer Notice, Osisko shall be entitled to provide written notice (the “Stream Participation Acceptance Notice”) to the Corporation stating that is wishes in principle to exercise its Stream Participation Right in respect of the Eligible Transaction based on the indicative terms set out in the Stream Offer Notice.

(5) Where Osisko has served a Stream Participation Acceptance Notice within the time period specified in Section 4.1(4) it shall be entitled to participate in the Eligible Transaction on the same terms and conditions (including with respect to price) as the Corporation. In the event Osisko does not provide a Stream Participation Acceptance Notice to the Corporation within the time period specified in Section 4.1(4), Osisko’s Stream Participation Right in respect of the Eligible Transaction specified in the applicable Stream Offer Notice shall terminate.

(6) Where Osisko has served a Stream Participation Acceptance Notice within the time period specified in Section 4.1(4), it shall thereafter be entitled to participate in negotiations and the Corporation shall keep Osisko informed of all relevant developments relating to the Eligible Transaction and provide Osisko with all other information that it may reasonably request in order to make informed decisions regarding the Eligible Transaction.

- 11 -

(7) If, following completion of negotiations with the third party counterparty or counterparties, the Corporation elects to enter into definitive documentation to proceed with the Eligible Transaction, then the Corporation shall promptly upon such election but in any case not later than fifteen (15) Business Days (or such shorter period as the Parties may agree) prior to the proposed date of closing of the Eligible Transaction give notice to Osisko (the “Stream Participation Right Election Notice”) which shall include:

a) the purchase price payable by Osisko if it elects to fully exercise its Stream Participation Right to acquire 20% of the Eligible Transaction;

b) all other material terms and conditions of the Eligible Transaction, including the draft share purchase agreement and the security agreement; and

c) any other information reasonably requested by Osisko in respect of the Eligible Transaction.

(8) Within 10 Business Days of receipt of the Stream Participation Right Election Notice, Osisko shall have the right to serve written notice to the Corporation electing to exercise its Stream Participation Right, which notice shall include the percentage of the Eligible Transaction Osisko is electing to acquire, which for the avoidance of doubt it shall acquire on the same terms and conditions (including with respect to price) as the Corporation.

(9) If the counterparty to the Eligible Transaction objects to Osisko’s participation in the Eligible Transaction (for whatever reason), the Corporation shall acquire Osisko’s portion of the relevant transaction and Osisko shall purchase such portion from the Corporation on the same terms and conditions (including with respect to price) as those agreed in the Eligible Transaction. The Corporation and Osisko shall work in good faith to agree definitive documentation in respect of such arrangement prior to, or concurrently with, the execution of the Eligible Transaction.

(10) Unless a Trigger Event has occurred, in consideration of the grant of the Stream Participation Right by the Corporation to Osisko, Osisko shall not, on its own behalf or on behalf of or in connection with any Person invest, participate or otherwise be commercially involved in any bona fide, confidential, privately-held carbon credit opportunity which has been introduced to Osisko by the Corporation.

4.2 Right to Participate in the Sale of Future Streams and Similar Transactions

(1) Unless a Trigger Event has occurred, the Corporation shall not, and shall cause each of its Affiliates not sell, transfer or otherwise dispose of all or part of its interest in or rights under any asset or agreement in respect of which Osisko has exercised its Stream Participation Right (each an “Eligible Right”), except as otherwise expressly permitted under this Section 4.2, without first having offered same to Osisko in writing (the “Stream Sale Notice”).

(2) If Osisko does not elect to acquire such an interest in an Eligible Right within thirty (30) Business Days of the Stream Sale Notice (or if Osisko elects to acquire an interest in an Eligible Right and such transaction does not close within sixty (60) Business Days of Osisko making an election in respect of a Stream Sale Notice, unless otherwise extended by the Parties acting reasonably and diligently) the Corporation shall then have the right to transfer its interest in such Eligible Right without further restriction on the same terms as offered to Osisko for a period of ninety (90) Business Days following such decision of Osisko not to so elect (or the failure to close the acquisition of the Eligible Right).

- 12 -

(3) If no transaction has been consummated by the Corporation or any of its Affiliates prior to the expiry of such 90 Business Day period with respect to the Eligible Right, then the terms of this Section 4.2 shall again come into effect with respect to such Eligible Right.

(4) The participation right will not terminate if, on receipt of any Stream Sale Notice from the Corporation, Osisko fails to or decides not to exercise it.

(5) Nothing in Section 4.2 restricts in any manner:

a) the disposition by a Party of an interest in the Right or this Agreement to an Affiliate; or

b) an amalgamation, merger, or other form of corporate reorganization or change of control transaction which is a bona fide business combination transaction that has the effect in law of the amalgamated or surviving corporation possessing, directly or indirectly, substantially all the properties, rights and interests and being subject to substantially all the debts, liabilities and obligations of the transferring Party.
