The Register shall be available for inspection by the Corporation or any Warrantholder during the Warrant Agent's regular business hours on a Business Day and upon payment to the Warrant Agent of its reasonable fees. Any Warrantholder exercising such right of inspection shall first provide an affidavit in form satisfactory to the Corporation and the Warrant Agent stating the name and address of the Warrantholder and agreeing not to use the information therein except in connection with an effort to call a meeting of Warrantholders or to influence the voting of Warrantholders at any meeting of Warrantholders.

(2)

Once an Uncertificated Warrant has been Authenticated, the information set forth in the Register with respect thereto at the time of Authentication may be altered, modified, amended, supplemented or otherwise changed only to reflect exercise or proper instructions to the Warrant Agent from the holder as provided herein, except that the Warrant Agent may act unilaterally to make purely administrative changes internal to the Warrant Agent and changes to correct errors. Each person who becomes a holder of an Uncertificated Warrant, by his, her or its acquisition thereof shall be deemed to have irrevocably (i) consented to the foregoing authority of the Warrant Agent to make such minor error corrections and (ii) agreed to pay to the Warrant Agent, promptly upon written demand, the full amount of all loss and expense (including without limitation reasonable legal fees of the Corporation and the Warrant Agent plus interest, at an appropriate then prevailing rate of interest to the Warrant Agent), sustained by the Corporation or the Warrant Agent as a proximate result of such error if but only if and only to the extent that such present or former holder realized any benefit as a result of such error and could reasonably have prevented, forestalled or minimized such loss and expense by prompt reporting of the error or avoidance of accepting benefits thereof whether or not such error is or should have been timely detected and corrected by the Warrant Agent; provided, that no person who is a bona fide purchaser shall have any such obligation to the Corporation or to the Warrant Agent.

2.10

Issue in Substitution for Warrant Certificates Lost, etc.

(1)

If any Warrant Certificate becomes mutilated or is lost, destroyed or stolen, the Corporation, subject to Applicable Legislation, shall issue and thereupon the Warrant Agent shall certify and deliver, a new Warrant Certificate of like tenor, and bearing the same legend, if applicable, as the one mutilated, lost, destroyed or stolen in exchange for and in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost, destroyed or stolen Warrant Certificate, and the substituted Warrant Certificate shall be in a form approved by the Warrant Agent and the Corporation and the Warrants evidenced thereby shall be entitled to the benefits hereof and shall rank equally in accordance with its terms with all other Warrants issued or to be issued hereunder.

(2)

The applicant for the issue of a new Warrant Certificate pursuant to this Section 2.10 shall bear the cost of the issue thereof and in case of loss, destruction or theft shall, as a condition precedent to the issuance thereof, furnish to the Corporation and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate so lost, destroyed or stolen as shall be satisfactory to the Corporation and to the Warrant Agent, in their sole discretion, and such applicant shall also be required to furnish an indemnity and surety bond in amount and form satisfactory to the Corporation and the Warrant Agent, in their sole discretion, and shall pay the reasonable charges of the Corporation and the Warrant Agent in connection therewith.

- 15 -

2.11

Exchange of Warrant Certificates

(1)

Any one or more Warrant Certificates representing any number of Warrants may, upon compliance with the reasonable requirements of the Warrant Agent (including compliance with applicable securities legislation), be exchanged for one or more other Warrant Certificates representing the same aggregate number of Warrants, and bearing the same legend, if applicable, as represented by the Warrant Certificate or Warrant Certificates so exchanged.

(2)

Warrant Certificates may be exchanged only at the Warrant Agency or at any other place that is designated by the Corporation with the approval of the Warrant Agent. Any Warrant Certificate from the holder (or such other instructions, in form satisfactory to the Warrant Agent), tendered for exchange shall be surrendered to the Warrant Agency and cancelled by the Warrant Agent.

2.12

Transfer and Ownership of Warrants

(1)

The Warrants may only be transferred on the Register kept by the Warrant Agent at the Warrant Agency by the holder or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent only upon (a) in the case of a Warrant Certificate, surrendering to the Warrant Agent at the Warrant Agency the Warrant Certificate representing the Warrants to be transferred together with a duly executed transfer form as set forth in Schedule "C", (b) in the case of Book Entry Only Warrants, in accordance with procedures prescribed by the Depository under the book entry registration system, (c) in the case of DRS Advices, surrendering to the Warrant Agent at the Warrant Agency, DRS Advices representing the Warrants to be transferred together with a duly executed form of transfer as set forth in Schedule "C" and (d) upon compliance with:

(i)

the conditions herein;

(ii)

such reasonable requirements as the Warrant Agent may prescribe; and

(iii)

all applicable securities legislation and requirements of regulatory authorities;

and, in the case of a Warrant Certificate, such transfer shall be duly noted in such Register by the Warrant Agent. Upon compliance with such requirements, the Warrant Agent shall issue to the transferee of a Certificated Warrant, a Warrant Certificate, to the transferee of a DRS Advice, a DRS Advice, or the Warrant Agent shall Authenticate and deliver a Warrant Certificate upon request that part of the CDS Global Warrant be certificated. Transfers within the systems of the Depository are not the responsibility of the Warrant Agent and will not be noted on the Register maintained by the Warrant Agent and Warrants that are held as Book Entry Only Warrants shall be transferred and recorded through the relevant Book Entry Only Participant in accordance with the book entry registration system as the entitlement holder in respect of such Warrants.

No duty shall rest with the Warrant Agent to determine compliance of the transferor or transferee with Applicable Securities Laws. The Warrant Agent shall be entitled to assume that all transfers are legal and proper.

(2)

Subject to the provisions of this Indenture and Applicable Legislation, the Warrantholder shall be entitled to the rights and privileges attaching to the Warrants, and the issue of Common Shares by the Corporation upon the exercise of Warrants in accordance with the terms and conditions herein contained shall discharge all responsibilities of the Corporation and the Warrant Agent with respect to such Warrants and neither the Corporation nor the Warrant Agent shall be bound to inquire into the title of any such holder.

- 16 -

2.13

Cancellation of Surrendered Warrants

All Warrant Certificates surrendered pursuant to Section 2.10, Section 2.11, Section 2.12, Article 3 or Section 5.1 shall be cancelled by the Warrant Agent and upon such circumstances all such Uncertificated Warrants shall be deemed cancelled and so noted on the Register by the Warrant Agent. Upon written request by the Corporation, the Warrant Agent shall furnish to the Corporation a cancellation certificate identifying the Warrant Certificates so cancelled, the number of Warrants evidenced thereby, the number of Common Shares, if any, issued pursuant to such Warrants and the details of any Warrant Certificates issued in substitution or exchange for such Warrant Certificates cancelled.

ARTICLE 3

EXERCISE OF WARRANTS

3.1

Right of Exercise

Subject to the provisions hereof, each Warrant shall entitle the holder, from the Effective Date and prior to the Expiry Time, to subscribe for and purchase that number of Common Shares equal to the Exchange Rate, at a price per share equal to the Exercise Price, all in accordance with the terms hereof and the conditions herein.

3.2

Warrant Exercise

(1)

Warrantholders of Warrant Certificates or DRS Advice who wish to exercise the Warrants held by them in order to acquire Common Shares must complete the exercise form (the " Exercise Notice") attached to the Warrant Certificate(s) which form is attached hereto as Schedule "D", which may be amended by the Corporation with the consent of the Warrant Agent, if such amendment does not, in the reasonable opinion of the Corporation and the Warrant Agent, which may be based on the advice of Counsel, materially and adversely affect the rights, entitlements and interests of the Warrantholders, and deliver such certificate(s) or DRS Advice, the executed Exercise Notice and a certified cheque, bank draft, wire transfer or money order payable to or to the order of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Warrants represented by a Warrant Certificate or evidenced by a DRS Advice shall be deemed to be surrendered upon personal delivery of such certificate or DRS Advice, Exercise Notice and aggregate Exercise Price or, if such documents are sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above.

A beneficial holder of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants in the book entry registration system who desires to exercise his or her Warrants must do so by causing a Book Entry Only Participant to deliver to the Depository on behalf of the entitlement holder, notice of the owner's intention to exercise Warrants in a manner acceptable to the Depository. Forthwith upon receipt by the Depository of such notice, as well as payment for the aggregate Exercise Price, the Depository shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (a "Confirmation") in a manner acceptable to the Warrant Agent, including by electronic means through a book based registration system, including CDSX. An electronic exercise of the Warrants initiated by the Book Entry Only Participant through a Book Based System, including CDSX, shall constitute a representation to both the Corporation and the Warrant Agent that the beneficial owner at the time of exercise of such Warrants (I) (a) is not in the United States; (b) is not a U.S. Person and is not exercising such Warrants on behalf of a U.S. Person or a person in the United States; (c) was not offered and did not acquire the Warrants in the United States; and (d) did not execute or deliver the notice of the owner's intention to exercise such Warrants in the United States or (II) is a QIB Purchaser, and the representations, warranties and covenants made by such QIB Purchaser in the Qualified Institutional Buyer Letter attached as Schedule C to the U.S. Subscription Agreement remain true and correct at the time of exercise. If the Book Entry Only Participant is not able to make or deliver the foregoing representation by initiating the electronic exercise of the Warrants, then such Warrants shall be required to be withdrawn from the Book Based System by the Book Entry Only Participant and an individually registered Warrant Certificate shall be issued by the Warrant Agent to such beneficial owner or Book Entry Only Participant and the exercise procedures set forth in Section 3.2(1) shall be followed (and provided, for greater certainty, that the foregoing does not apply, in the case of a QIB Purchaser who complies with Section 3.3(2)).

- 17 -

(2)

Subject to Section 3.3(2) below, the Warrants may not be exercised by or on behalf of a person in the United States or a U.S. Person.

(3)

Payment representing the aggregate Exercise Price must be provided to the appropriate office of the Book Entry Only Participant in a manner acceptable to it. A notice in form acceptable to the Book Entry Only Participant and payment from such beneficial holder should be provided to the Book Entry Only Participant sufficiently in advance so as to permit the Book Entry Only Participant to deliver notice and payment to the Depository and for the Depository in turn to deliver notice and payment to the Warrant Agent prior to the Expiry Time. The Depository will initiate the exercise by way of the Confirmation and forward the aggregate Exercise Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by causing the issuance to the Depository through the book entry registration system of the Common Shares to which the exercising Warrantholder is entitled pursuant to the exercise. Any expense associated with the exercise process will be for the account of the entitlement holder exercising the Warrants and/or the Book Entry Only Participant exercising the Warrants on its behalf.

(4)

By causing a Book Entry Only Participant to deliver notice to the Depository, a beneficial holder shall be deemed to have irrevocably surrendered his, her or its Warrants so exercised and appointed such Book Entry Only Participant to act as his, her or its exclusive settlement agent with respect to the exercise of the Warrants and the receipt of Common Shares in connection with the obligations arising from such exercise.

(5)

Any notice which the Depository determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a Book Entry Only Participant to exercise or to give effect to the settlement thereof in accordance with the beneficial holder's instructions will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the Book Entry Only Participant or the Warrantholder.

(6)

Any exercise form or Exercise Notice referred to in this Section 3.2 shall be signed by the registered Warrantholder, or its executors or administrators or other legal representatives or an attorney of the registered Warrantholder, duly appointed by an instrument in writing satisfactory to the Warrant Agent but such exercise form or Exercise Notice need not be executed by the Depository.

(7)

Any exercise referred to in this Section 3.2 shall require that the entire Exercise Price for Common Shares subscribed must be paid at the time of subscription and such Exercise Price and original Exercise Notice executed by the registered Warrantholder or the Confirmation from the Depository must be received by the Warrant Agent prior to the Expiry Time.

- 18 -

(8)

If the form of Exercise Notice set forth in the Warrant Certificate shall have been amended, the Corporation shall cause the amended Exercise Notice to be forwarded to all Warrantholders.

(9)

Exercise Notices and Confirmations must be delivered to the Warrant Agent at any time during the Warrant Agent's actual business hours on any Business Day prior to the Expiry Time. Any Exercise Notice or Confirmations received by the Warrant Agent after business hours on any Business Day other than the Expiry Date will be deemed to have been received by the Warrant Agent on the next following Business Day.

(10)

Any Warrant with respect to which a Confirmation or valid exercise is not received by the Warrant Agent before the Expiry Time shall be deemed to have expired and become void and all rights with respect to such Warrants shall terminate and be cancelled.

3.3

Prohibition on Exercise by Persons in the United States and U.S. Persons

(1)

Subject to Section 3.3(2) below, (i) Warrants may not be exercised within the United States or by or on behalf of any person in the United States or U.S. Person; and (ii) no Common Shares issued upon exercise of Warrants may be delivered to any address in the United States unless such securities are registered under the U.S. Securities Act and the securities laws of all applicable states of the United States.

(2)

Notwithstanding Section 3.2(2) or Section 3.3(1), (i) Warrants may be exercised in the United States or by or on behalf of a person in the United States or U.S. Person, and (ii) Common Shares issued upon exercise of any such Warrants may be delivered to an address in the United States, provided that:

(a)

the person exercising the Warrants is a QIB Purchaser with respect to those Warrants that originally executed a U.S. Subscription Agreement and the representations, warranties and covenants made by such QIB Purchaser in the Qualified Institutional Buyer Letter attached as Schedule "C" to the U.S. Subscription Agreement remain true and correct at the time of exercise and any exercise of Warrants without the delivery of an opinion of counsel or other evidence shall be deemed a representation and warranty to the Corporation to that effect or has provided an opinion of counsel of recognized standing in form and substance reasonably satisfactory to the Corporation that the exercise of the Warrants and the issuance of the Common Shares are exempt from the registration requirements of the U.S. Securities Act and applicable state securities laws. Any certificates representing Common Shares issued to a Qualified Institutional Buyer shall not bear any legend for purposes of the U.S. Securities Act, or

(b)

the person exercising the Warrants (i) has executed and delivered to the Warrant Agent a subscription form as attached to the Warrant Certificate and that such person is an "accredited investor" (that satisfies the criteria set forth in Rule 501(a) of Regulation D under the U.S. Securities Act) (a "U.S. Accredited Investor") exercising the Warrants for its own account or the account of a U.S. Accredited Investor over which it exercises sole investment discretion, (ii) understands that the Common Shares have not been registered under the U.S. Securities Act or the securities laws of any state of the United States, (iii) has provided such documentation as the Corporation may reasonably require to meet the requirements of the U.S. Securities Act and (iv) agrees to the restrictions on transfer and resale more fully described in this Indenture. Any certificates representing Common Shares issued to a U.S. Accredited Investor that is not a Qualified Institutional Buyer pursuant to this Section 3.3(2)(b) shall bear the U.S. Common Share Legend until such time as the U.S. Common Share Legend is no longer required under applicable requirements of the U.S. Securities Act or applicable state securities laws.

- 19 -

(3)

Common Shares issued upon the exercise of Warrants by a U.S. Accredited Investor that is not a Qualified Institutional Buyer shall be represented by definitive certificates and shall bear the following legend (the "U.S. Common Share Legend") until such time as the same is no longer required under applicable requirements of the U.S. Securities Act or applicable state securities laws:

"THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT"), OR UNDER ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF OSISKO DEVELOPMENT CORP. (THE "CORPORATION") THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES, IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, (C) PURSUANT TO THE EXEMPTIONS FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY (1) RULE 144, IF AVAILABLE, OR (2) RULE 144A THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, PROVIDED THAT IN THE CASE OF TRANSFERS PURSUANT TO (C)(1) OR (D) ABOVE, A LEGAL OPINION IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION MUST FIRST BE PROVIDED TO THE CORPORATION'S TRANSFER AGENT.

DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA."

provided that: (i) if any such Common Shares are being sold outside the United States in accordance with Rule 904 of Regulation S under the U.S. Securities Act, the U.S. Common Share Legend may be removed by providing a declaration to the registrar and Transfer Agent in the form attached hereto as Schedule "E", or such form as the Corporation may from time to time prescribe, together with together with any other evidence, which may include an opinion of counsel of recognized standing reasonably satisfactory to the Corporation, to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act; and (ii) if any such Common Shares are being sold pursuant to Rule 144 under the U.S. Securities Act, the U.S. Common Share Legend may be removed by delivery to the Corporation and Transfer Agent of an opinion of counsel of recognized standing reasonably satisfactory to the Corporation to the effect that the U.S. Common Share Legend is no longer required under applicable requirements of the U.S. Securities Act.

- 20 -

3.4

Transfer Fees and Taxes

If any of the Common Shares subscribed for are to be issued to a person or persons other than the registered Warrantholder, the registered Warrantholder shall execute the form of transfer as set forth in Schedule "C" and will comply with such reasonable requirements as the Warrant Agent may stipulate and will pay to the Corporation, or the Warrant Agent on behalf of the Corporation, all applicable transfer or similar taxes and the Corporation will not be required to issue or deliver certificates or DRS Advices evidencing Common Shares unless or until such Warrantholder shall have paid to the Corporation or the Warrant Agent on behalf of the Corporation, the amount of such tax or shall have established to the satisfaction of the Corporation and the Warrant Agent that such tax has been paid or that no tax is due.

3.5

Warrant Agency

To facilitate the exchange, transfer or exercise of Warrants and compliance with such other terms and conditions hereof as may be required, the Corporation has appointed the Warrant Agency as the agency at which Warrants may be surrendered for exchange or transfer or at which Warrants may be exercised and the Warrant Agent has accepted such appointment. The Corporation may from time to time designate alternate or additional places as the Warrant Agency (subject to the Warrant Agent's prior approval) and will give notice to the Warrant Agent of any proposed change of the Warrant Agency. Branch registers shall also be kept at such other place or places, if any, as the Corporation, with the approval of the Warrant Agent, may designate. The Warrant Agent will from time to time when requested to do so by the Corporation or any registered Warrantholder, upon payment of the Warrant Agent's reasonable charges, furnish a list of the names and addresses of Warrantholders showing the number of Warrants held by each such registered Warrantholder.

3.6

Effect of Exercise of Warrants

(1)

Upon the exercise of Warrants pursuant to and in compliance with Section 3.2 and subject to Section 3.3, the Common Shares to be issued pursuant to the Warrants exercised shall be deemed to have been issued and the person or persons to whom such Common Shares are to be issued shall be deemed to have become the holder or holders of such Common Shares on the Exercise Date unless the Register shall be closed on such date, in which case the Common Shares subscribed for shall be deemed to have been issued, and such person or persons deemed to have become the holder or holders of record of such Common Shares, on the date on which such Register is reopened.

(2)

Within five Business Days after the Exercise Date with respect to a Warrant, the Warrant Agent shall use commercially reasonable efforts to cause to be delivered or mailed to the person or persons in whose name or names the Warrant is registered or, if so specified in writing by the holder, cause to be delivered to such person or persons at the Warrant Agency where the Warrant Certificate was surrendered, a certificate or certificates or DRS Advices for the appropriate number of Common Shares subscribed for, or any other appropriate evidence of the issuance of Common Shares to such person or persons in respect of Common Shares issued under the book entry registration system or direct registration system.

3.7

Partial Exercise of Warrants; Fractions

(1)

A holder of Warrants may exercise his, her or its right to acquire a number of whole Common Shares less than the aggregate number which the holder is entitled to acquire pursuant to such Warrants. In the event of any exercise of a number of Warrants less than the number which the holder is entitled to exercise, the holder of Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate(s), bearing the same legend, if applicable, or other appropriate evidence of Warrants, in respect of the balance of the Warrants held by such holder and which were not then exercised.

- 21 -

(2)

Notwithstanding anything herein contained, including any adjustment provided for in Section 4.1, the Corporation shall not be required, upon the exercise of any Warrants, to issue fractions of Common Shares. Warrants may only be exercised in a sufficient number to acquire whole numbers of Common Shares. If, upon the exercise of Warrants by a person, the aggregate number of Common Shares to be issued to such person includes a fractional Common Share, the number of Common Shares to be issued to such person shall be rounded down to the nearest whole number and no consideration shall be paid for any such fractional Common Share.

3.8

Expiration of Warrants

From and after the Expiry Time, all rights under any Warrant in respect of which the right of acquisition provided for herein shall not have been exercised shall cease and terminate and each Warrant shall be void and of no further force or effect.

3.9

Accounting and Recording

(1)

The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised, and shall promptly forward to the Corporation (or into an account or accounts of the Corporation with the bank or trust company designated by the Corporation for that purpose), all monies received by the Warrant Agent on the subscription of Common Shares through the exercise of Warrants. All such monies and any securities or other instruments from time to time received by the Warrant Agent shall be received in trust for, and shall be segregated and kept apart by the Warrant Agent for, the Warrantholders and the Corporation as their interests may appear.

(2)

The Warrant Agent shall record the particulars of Warrants exercised, which particulars shall include the names and addresses of the persons who become holders of Common Shares on exercise and the Exercise Date, in respect thereof. The Warrant Agent shall provide such particulars in writing to the Corporation within five Business Days of any request by the Corporation therefor.

3.10

Securities Restrictions

Notwithstanding anything herein contained, no Warrants, or Common Shares issuable upon the exercise of such Warrants, will be issued if the issuance of such Warrants or Common Shares would constitute a violation of the securities laws of any applicable jurisdiction, and, without limiting the generality of the foregoing, the Corporation may include any legend on the certificates or DRS Advices representing the Warrants and Common Shares issuable upon exercise of any Warrant if, in the opinion of counsel to the Corporation, such legend is necessary in order to avoid a violation of any securities laws of any applicable jurisdiction or to comply with the requirements of any stock exchange on which the Common Shares are listed; provided that if, at any time, in the opinion of outside counsel to the Corporation, acting reasonably, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate or DRS Advices, at his, her or its expense, provides the Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel of recognized standing satisfactory to the Corporation) to the effect that such holder is entitled to sell or otherwise transfer such securities in a transaction in which such legends are not required, such legended certificates or DRS Advices may thereafter be surrendered to the Warrant Agent in exchange for a certificate or DRS Advices that does not bear such legends.

- 22 -

The Warrant Agent shall be entitled to assume that the Common Shares may be issued pursuant to the exercise of any Warrant without violating any Applicable Securities Laws and without legending the certificate or DRS Advices representing the Common Shares unless the Warrant Agent has received notice in writing from the Corporation stating otherwise and setting forth the restrictions on the exercise of the Warrants and any legend the certificates or DRS Advices representing the Common Shares should bear.

ARTICLE 4

ADJUSTMENT OF NUMBER OF COMMON SHARES AND EXERCISE PRICE

4.1

Adjustment of Number of Common Shares and Exercise Price

The subscription rights in effect under the Warrants for Common Shares issuable upon the exercise of the Warrants shall be subject to adjustment from time to time as follows:

(a)

if, at any time after the Effective Date but prior to the Expiry Date, the Corporation shall:

(i)

subdivide, re-divide or change its outstanding Common Shares into a greater number of Common Shares;

(ii)

reduce, combine or consolidate its outstanding Common Shares into a lesser number of Common Shares; or

(iii)

issue Common Shares or securities exchangeable for, or convertible into, Common Shares to the holders of all or substantially all of the Common Shares by way of a stock dividend or other distribution (other than a distribution of Common Shares upon the exercise of Warrants or any outstanding options or a distribution to the holders of all or substantially all of the Common Shares on its outstanding Common Shares payable in Common Shares or securities convertible into or exchangeable for Common Shares);

(any of such events in Section 4.1(a)(i), (ii) or (iii) being called an "Common Share Recapitalization"), then, in each case:

(iv)

the Exercise Price shall be adjusted as of the effective date or record date of such Common Share Recapitalization so that it shall equal the amount, in dollars, determined by multiplying the Exercise Price in effect immediately prior to such effective date or record date by a fraction, the numerator of which shall be the number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Recapitalization, and the denominator of which shall be the number of Common Shares outstanding as of the effective date or record date after giving effect to such Common Share Recapitalization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities been exchanged for or converted into Common Shares on such record date or effective date);

(v)

concurrently with any adjustment of the Exercise Price pursuant to this Section 4.1(a), the Exchange Rate shall be adjusted so that it shall equal the amount determined by multiplying the Exchange Rate in effect immediately prior to such adjustment by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; and

- 23 -

(vi)

any adjustments required under this Section 4.1(a) shall be made successively whenever any Common Share Recapitalization shall occur;

(b)

if and whenever, at any time after the Effective Date but prior to the Expiry Date, the Corporation shall fix a record date for the issuance of rights, options or warrants to all or substantially all the holders of outstanding Common Shares entitling them, for a period expiring not more than 45 days after such record date ("Rights Offering Exercise Period"), to subscribe for or purchase Common Shares (or securities convertible or exchangeable into Common Shares) at a price per Common Share (or having a conversion or exchange price per Common Share) less than 95% of the Current Market Price on such record date (a "Rights Offering"), then, in each case:

(i)

the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount, in dollars, determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date plus that number of Common Shares determined by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase or into which the convertible or exchangeable securities so offered are convertible or exchangeable; for purposes of the foregoing calculation, any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding;

(ii)

to the extent that no such rights or warrants are exercised prior to the expiry of the Rights Offering Exercise Period, the Exercise Price shall, upon expiry of the Rights Offering Exercise Period, be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed;

(iii)

if any such rights or warrants are exercised, the Exercise Price shall, upon such exercise, be adjusted to the Exercise Price which would otherwise be determined under Section 4.1(b)(i) if each reference therein to "offered for subscription or purchase" were replaced by a reference to "issued upon the exercise of such rights or warrants" and each reference therein to "so offered" were replaced by a reference to "so purchased";

(iv)

concurrently with any adjustment of the Exercise Price pursuant to this Section 4.1(b), the Exchange Rate will be adjusted so that it will equal the amount determined by multiplying the Exchange Rate in effect immediately prior to such adjustment by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; and

- 24 -

(v)

any adjustments required by this Section 4.1(b) shall be made successively whenever a record date for a Rights Offering is fixed ( provided that if two or more such record dates or are fixed within a period of 25 Trading Days, such adjustment will be made successively as if each of such record dates occurred on the earliest of such record dates);

(c)

if and whenever at any time after the Effective Date but prior to the Expiry Date the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of outstanding Common Shares of (i) securities of any class, whether of the Corporation or any other person (other than Common Shares), (ii) rights, options or warrants to subscribe for or purchase Common Shares (or other securities convertible into or exchangeable for Common Shares), other than pursuant to a Rights Offering; (iii) evidences of its indebtedness, or (iv) any property or other assets (but excluding any distribution referred to in Section 4.1(a) or Section 4.1(b)), then, in each such case:

(i)

the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount, in dollars, determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price on such record date, less the excess, if any, of the fair market value on such record date, as determined by the Corporation (subject to Exchange approval), of such securities or other assets so issued or distributed over the fair market value of any consideration received therefor by the Corporation from the holders of the Common Shares, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price; for purposes of the foregoing calculation, any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding;

(ii)

to the extent no such distribution is made, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed;

(iii)

concurrently, with any adjustment of the Exercise Price pursuant to this Section 4.1(c), the Exchange Rate will be adjusted so that it will equal the amount determined by multiplying the Exchange Rate in effect immediately prior to such adjustment by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; and

(iv)

any adjustments required by this Section 4.1(c) shall be made successively whenever such a record date is fixed;

(d)

if and whenever at any time after the Effective Date but prior to the Expiry Date there is a reclassification or redesignation of the Common Shares, or a capital reorganization of the Corporation (other than as described in Section 4.1(a), Section 4.1(b) or Section 4.1(c)) or a consolidation, amalgamation, arrangement, merger or other form of business combination of the Corporation with or into any other body corporate, trust, partnership or other entity that results in any reclassification of the Common Shares or any change or exchange of the Common Shares into or for other securities or any sale, lease, exchange, transfer or conveyance of the property, undertaking and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity (any of such events being a "Capital Reorganization"), any registered Warrantholder who has not exercised its right of acquisition prior to the effective date of such Capital Reorganization, upon the exercise of such right thereafter, shall be entitled to receive upon payment of the Exercise Price and shall accept, in lieu of the number of Common Shares that prior to such effective date the registered Warrantholder would have been entitled to receive, the number of shares or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such Capital Reorganization, that such registered Warrantholder would have been entitled to receive on such Capital Reorganization, if, on the effective date thereof, as the case may be, the registered Warrantholder had been the registered holder of the number of Common Shares to which prior to such effective date it was entitled to acquire upon the exercise of the Warrants. If determined appropriate by the Warrant Agent, relying on advice of Counsel, to give effect to or to evidence the provisions of this Section 4.1(d), the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the case may be, shall, prior to or contemporaneously with any such Capital Reorganization, enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the Warrantholders to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which a registered Warrantholder is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Warrant Agent pursuant to the provisions of this Section 4.1(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 8 hereof. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Warrant Agent shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 4.1 and which shall apply to successive reclassifications, redesignations, capital reorganizations, arrangements, amalgamations, consolidations, mergers, sales or conveyances;

(e)

in any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the registered Warrantholder of any Warrant exercised after the record date and prior to completion of such event the additional Common Shares issuable by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such registered Warrantholder an appropriate instrument evidencing such registered Warrantholder's right to receive such additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise or such later date as such registered Warrantholder would, but for the provisions of this Section 4.1(e), have become the holder of record of such additional Common Shares pursuant to Section 4.1;

(f)

in any case in which Section 4.1(a)(iii), Section 4.1(b) or Section 4.1(c) require that an adjustment be made to the Exercise Price, no such adjustment shall be made if the Warrantholders of the outstanding Warrants receive, subject to any required stock exchange or regulatory approval, the rights or warrants referred to in Section 4.1(a)(iii), Section 4.1(b) or the shares, rights, options, warrants, evidences of indebtedness or assets referred to in Section 4.1(c), as the case may be, in such kind and number as they would have received if they had been holders of Common Shares on the applicable record date or effective date, as the case may be, by virtue of their outstanding Warrant having then been exercised into Common Shares at the Exercise Price in effect on the applicable record date or effective date, as the case may be;

- 26 -

(g)

the adjustments provided for in this Section 4.1 are cumulative, and shall, in the case of adjustments to the Exercise Price be computed to the nearest whole cent and shall apply to successive subdivisions, re-divisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section 4.1, provided that, notwithstanding any other provision of this Section 4.1, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect; provided, however, that any adjustments which by reason of this Section 4.1(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; and

(h)

after any adjustment pursuant to this Section 4.1, the term "Common Shares" where used in this Indenture shall be interpreted to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, the registered Warrantholder is entitled to receive upon the exercise of this Warrant, and the number of Common Shares indicated by any exercise made pursuant to a Warrant shall be interpreted to mean the number of Common Shares and other property or securities a registered Warrantholder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, upon the full exercise of a Warrant.

4.2

Entitlement to Common Shares on Exercise of Warrant

All Common Shares, or shares of any class or other securities, which a registered Warrantholder is at the time in question entitled to receive on the exercise of its Warrant, whether or not as a result of adjustments made pursuant to this Article 4, shall, for the purposes of the interpretation of this Indenture, be deemed to be Common Shares which such registered Warrantholder is entitled to acquire pursuant to such Warrant.

4.3

No Adjustment for Certain Transactions

Notwithstanding anything in this Article 4, no adjustment shall be made under Section 4.1 in respect of any issuance of Common Shares (i) pursuant to any stock option, stock purchase, restricted share plan or other equity incentive plan in force from time to time for officers, directors or employees, consultants or other service providers of the Corporation, or (ii) pursuant to any stock option granted or other convertible security issued by the Corporation prior to the date of this Indenture.

4.4

Determination by Independent Firm

In the event of any question arising with respect to the adjustments provided for in this Article 4, such question shall be conclusively determined by an independent firm of chartered accountants other than the Auditors, who shall have access to all necessary records of the Corporation, and such determination shall be binding upon the Corporation, the Warrant Agent, all holders and all other persons interested therein.

- 27 -

4.5

Proceedings Prior to any Action Requiring Adjustment

As a condition precedent to the taking of any action which would require an adjustment in any of the acquisition rights pursuant to any of the Warrants, including the Exercise Price and number of Common Shares which are to be received upon the exercise thereof, the Corporation shall take any action which may, in the opinion of Counsel (acting reasonably), be necessary in order that the Corporation has unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non- assessable all the Common Shares which the holders of such Warrants are entitled to receive on the full exercise thereof in accordance with the provisions hereof.

4.6

Certificate of Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 4.1, deliver a certificate of the Corporation to the Warrant Agent specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate shall be supported by a certificate of the Auditors verifying such calculation. The Warrant Agent shall act and rely, and shall be protected in acting and relying, upon the certificate of the Corporation or of the Auditors and any other document filed by the Corporation pursuant to this Article 4 for all purposes.

4.7

Notice of Special Matters

The Corporation covenants with the Warrant Agent that, so long as any Warrant remains outstanding, it will give notice to the Warrant Agent and to the Warrantholders of its intention to fix a record date that is prior to the Expiry Date for any matter for which an adjustment may be required pursuant to Section 4.1. Such notice shall specify the particulars of such event and the record date for such event, provided that the Corporation shall only be required to specify in the notice such particulars of the event as shall have been fixed and determined on the date on which the notice is given. The notice shall be given in each case not less than 14 days prior to such applicable record date. If notice has been given and the adjustment is not then determinable, the Corporation shall promptly, after the adjustment is determinable, file with the Warrant Agent a computation of the adjustment and give notice to the Warrantholders of such adjustment computation.

4.8

No Action after Notice

The Corporation covenants with the Warrant Agent that it will not close its transfer books or take any other corporate action which might deprive the registered Warrantholder of the opportunity to exercise its right of acquisition pursuant thereto during the period of 14 days after the giving of the certificate or notices set forth in Section 4.6 and Section 4.7.

4.9

Other Action

If the Corporation, after the date hereof, shall take any action affecting the Common Shares, other than an action described in Section 4.1 or an action referred to in Section 4.3, which in the reasonable opinion of the directors of the Corporation would materially affect the rights of Warrantholders, the Exercise Price and/or Exchange Rate shall be adjusted in such manner and at such time, by action of the directors, acting reasonably and in good faith, as they in their sole discretion may determine to be equitable to the Warrantholders in the circumstances, provided that no such adjustment will be made unless any requisite prior approval of any stock exchange on which the Common Shares are or may be listed for trading has been obtained.

- 28 -

4.10

Protection of Warrant Agent

The Warrant Agent shall not:

(a)

at any time be under any duty or responsibility to any registered Warrantholder to determine whether any facts exist which may require any adjustment contemplated by Section 4.1, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same;

(b)

be accountable with respect to the validity or value (or the kind or amount) of any Common Shares or of any other securities or property which may at any time be issued or delivered upon the exercise of the rights attaching to any Warrant;

(c)

be responsible for any failure of the Corporation to issue, transfer or deliver Common Shares or certificates for the same upon the surrender of any Warrants for the purpose of the exercise of such rights or to comply with any of the covenants contained in this Article; and

(d)

incur any liability or be in any way responsible for the consequences of any breach on the part of the Corporation of any of the representations, warranties or covenants herein contained or of any acts of the directors, officers, employees, agents or servants of the Corporation.

4.11

Participation by Warrantholder

No adjustments shall be made pursuant to this Article 4 if the Warrantholders are entitled to participate in any event described in this Article 4 on the same terms, mutatis mutandis, as if the Warrantholders had exercised their Warrants prior to, or on the effective date or record date of, such event.

4.12

Regulatory Approval of Adjustments

Notwithstanding the foregoing, any adjustment to the Exercise Price and/or Exchange Rate shall be subject to the prior written consent of the Exchange.

ARTICLE 5

RIGHTS OF THE CORPORATION AND COVENANTS

5.1

Optional Purchases by the Corporation

Subject to compliance with applicable securities legislation and approval of applicable regulatory authorities, if any, the Corporation may from time to time purchase, by private contract or otherwise, any of the Warrants.

In the case of Certificated Warrants, Warrant Certificates representing the Warrants purchased pursuant to this Section 5.1 shall forthwith be delivered to and cancelled by the Warrant Agent and reflected accordingly on the Register of Warrants.

Suits by Warrantholders

All or any of the rights conferred upon any registered Warrantholder by any of the terms of this Indenture may be enforced by the registered Warrantholder by appropriate proceedings but without prejudice to the right which is hereby conferred upon the Warrant Agent to proceed in its own name to enforce each and all of the provisions herein contained for the benefit of the Warrantholders from time to time outstanding.

Such notice shall state the time when and the place where the meeting is to be held, shall state briefly the general nature of the business to be transacted thereat and shall contain such information as is reasonably necessary to enable the Warrantholders to make a reasoned decision on the matter, but it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Section 7.2.

(i)

to assent to any compromise or arrangement with any creditor or creditors or any class or classes of creditors, whether secured or otherwise, and with holders of any shares or other securities of the Corporation.

7.11

Meaning of Extraordinary Resolution

(1)

The expression "Extraordinary Resolution" when used in this Indenture means, subject as hereinafter provided in this Section 7.11 and in Section 7.14, a resolution: (i) proposed at a meeting of Warrantholders duly convened for that purpose and held in accordance with the provisions of this Article 7 at which there are present in person or by proxy Warrantholders holding in the aggregate at least 25% of the aggregate number of Warrants then outstanding and passed by the affirmative votes of Warrantholders holding not less than 66 2/3% of the aggregate number of Warrants then outstanding at the meeting and voted on the poll upon such resolution; or (ii) in writing signed by the holders of at least 66 2/3% of the then outstanding Warrants on any matter that would otherwise be voted upon at a meeting called to approve such resolution as contemplated in this Section 7.11(1).

(2)

If, at the meeting at which an Extraordinary Resolution is to be considered, Warrantholders holding at least 25% of the aggregate number of Warrants then outstanding are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by Warrantholders or on a Warrantholders' Request, shall be dissolved; but in any other case it shall stand adjourned to such day, being not less than 15 or more than 60 days later, and to such place and time as may be appointed by the chair. Not less than 14 days' prior notice shall be given of the time and place of such adjourned meeting in the manner provided for in Section 10.2. Such notice shall state that at the adjourned meeting the Warrantholders present in person or by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars. At the adjourned meeting the Warrantholders present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided in Section 7.11(1) shall be an Extraordinary Resolution within the meaning of this Indenture notwithstanding that Warrantholders holding at least 25% of the aggregate number of the then outstanding Warrants are not present in person or by proxy at such adjourned meeting.

- 35 -

(3)	Subject to Section 7.14, votes on an Extraordinary Resolution shall always be given on a poll and no demand for a poll on an Extraordinary Resolution shall be necessary.

7.12

Powers Cumulative

Any one or more of the powers or any combination of the powers in this Indenture stated to be exercisable by the Warrantholders by Extraordinary Resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers or any combination of powers from time to time shall not be deemed to exhaust the right of the Warrantholders to exercise such power or powers or combination of powers then or thereafter from time to time.

7.13

Minutes

Minutes of all resolutions and proceedings at every meeting of Warrantholders shall be made and duly entered in books to be provided from time to time for that purpose by the Warrant Agent at the expense of the Corporation, and any such minutes as aforesaid, if signed by the chair or the secretary of the meeting at which such resolutions were passed or proceedings had shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting in respect of the proceedings of which minutes shall have been made shall be deemed to have been duly convened and held, and all resolutions passed thereat or proceedings taken shall be deemed to have been duly passed and taken.

7.14

Rights and Duties of Warrant Agent

(1)

In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall exercise that degree of care, diligence and skill that a reasonably prudent warrant agent would exercise in comparable circumstances.

(2)

The obligation of the Warrant Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing, when required by notice by the Warrant Agent, sufficient funds to commence or to continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent to protect and to hold harmless the Warrant Agent and its officers, directors, employees and agents, against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof.

The Warrant Agent may, before commencing or at any time during the continuance of any such act, action or proceeding, require the Warrantholders, at whose instance it is acting to deposit with the Warrant Agent the Warrants Certificates held by them, for which Warrants the Warrant Agent shall issue receipts.

The Warrant Agent has sole discretion and shall be protected in acting and relying upon any Document received either in facsimile or by e-mail of a pdf form.

- 39 -

(3)

Whenever it is provided in this Indenture or under Applicable Legislation that the Corporation shall deposit with the Warrant Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Corporation to have the Warrant Agent take the action to be based thereon.

(4)

Whenever Applicable Legislation requires that evidence referred to in Section 9.3(1) be in the form of a statutory declaration, the Warrant Agent may accept such statutory declaration in lieu of a certificate of the Corporation required by any provision hereof. Any such statutory declaration may be made by one or more of the Chair of the board of directors and Chief Executive Officer, President and Chief Operating Officer, Executive Vice-President, Vice-President, Secretary, Controller, Treasurer, or any Assistant-Secretary or Assistant-Treasurer of the Corporation.

(5)

Proof of the execution of an instrument in writing, including a Warrantholders' Request, by any Warrantholder may be made by the certificate of a notary, solicitor or commissioner for oaths, or other officer with similar powers, that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Warrant Agent may consider adequate and in respect of a corporate Warrantholder, shall include a certificate of incumbency of such Warrantholder together with a certified resolution authorizing the person who signs such instrument to sign such instrument.

(6)

The Warrant Agent may employ or retain such Counsel, accountants, appraisers or other experts or advisers as it may reasonably require for the purpose of discharging and determining its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any Counsel, and shall not be responsible for any misconduct or negligence on the part of any such Counsel, experts or advisers who have been appointed with due care by the Warrant Agent. The Corporation shall pay or reimburse the Warrant Agent for any reasonable fees, expenses and disbursements of such Counsel or advisers.

(7)

The Warrant Agent may act and rely and shall be protected in acting and relying in good faith on the opinion or advice of or information obtained from any Counsel, accountant, appraiser, engineer or other expert or adviser in good standing and who in good faith the Warrant Agent determined would be appropriately able to give such opinion, advice or information, whether retained or employed by the Corporation or by the Warrant Agent, in relation to any matter arising in the administration of the agency hereof.

All amounts held by the Warrant Agent pursuant to this Indenture shall be held by the Warrant Agent for the Corporation and the delivery of the funds to the Warrant Agent shall not give rise to a debtor-creditor or other similar relationship. The amounts held by the Warrant Agent pursuant to this Indenture are at the sole risk of the Corporation and, without limiting the generality of the foregoing, the Warrant Agent shall have no responsibility or liability for any diminution of the funds which may result from any deposit made with an Approved Bank pursuant to this section, including any losses resulting from a default by the Approved Bank or other credit losses (whether or not resulting from such a default). The parties hereto acknowledge and agree that the Warrant Agent will have acted prudently in depositing the funds at any Approved Bank, and that the Warrant Agent is not required to make any further inquiries in respect of any such bank.

Rights of Rescission and Withdrawal for Holders

Should a holder of Warrants exercise any legal, statutory, contractual or other right of withdrawal or rescission that may be available to it, and the holder's funds which were paid on exercise have already been released to the Corporation by the Warrant Agent, the Warrant Agent shall not be responsible for ensuring the exercise is cancelled and a refund is paid back to the holder. In such cases, the holder shall seek a refund directly from the Corporation and subsequently, the Corporation, upon surrender to the Corporation or the Warrant Agent of any underlying Common Shares or other securities that may have been issued, or such other procedure as agreed to by the parties hereto, shall instruct the Warrant Agent in writing, to cancel the exercise transaction and any such underlying Common Shares or other securities on the register, which may have already been issued upon the Warrant exercise. In the event that any payment is received by the holder from the Corporation by virtue of the holder being a Shareholder for such Warrants that were subsequently rescinded, such payment must be returned to the Corporation by such holder. The Warrant Agent shall not be under any duty or obligation to take any steps to ensure or enforce the return of the funds pursuant to this section, nor shall the Warrant Agent be in any other way responsible in the event that any payment is not delivered or received pursuant to this section. Notwithstanding the foregoing, in the event that the Corporation provides the refund to the Warrant Agent for distribution to the holder, the Warrant Agent shall return such funds to the holder as soon as reasonably practicable, and in so doing, the Warrant Agent shall incur no liability with respect to the delivery or non-delivery of any such funds.

To acquire Common Shares of

OSISKO DEVELOPMENT CORP.

(existing pursuant to the federal laws of Canada)

Warrant		Certificate for
Certificate No.		Warrants, each entitling the holder to acquire one Common Share (subject to adjustment as provided for in the Warrant Indenture (as defined below))

		CUSIP 68828E270

		ISIN CA68828E2704

THIS IS TO CERTIFY THAT, for value received,

(the "Warrantholder") is the registered holder of the number of common share purchase warrants (the "Warrants") of Osisko Development Corp. (the "Corporation") specified above, and is entitled, on exercise of these Warrants upon and subject to the terms and conditions set forth herein and in the Warrant Indenture, to purchase at any time before 5:00 p.m. (Toronto time) (the " Expiry Time") on October 1, 2029 (the "Expiry Date"), one fully paid and non-assessable common share without par value in the capital of the Corporation as constituted on the date hereof (a "Common Share") for each Warrant, subject to adjustment in accordance with the terms of the Warrant Indenture.

The right to purchase Common Shares may only be exercised by the Warrantholder within the time set forth above by:

(a)	duly completing and executing the exercise form (the "Exercise Form") attached hereto; and

(b)

surrendering this warrant certificate (the "Warrant Certificate"), with a duly completed Exercise Form, to the Warrant Agent at one of the principal offices of the Warrant Agent, in the City of Toronto, together with a certified cheque, bank draft, wire transfer or money order in the lawful money of Canada payable to or to the order of the Corporation in an amount equal to the purchase price of the Common Shares so subscribed for.

The surrender of this Warrant Certificate, the duly completed Exercise Form and payment as provided above will be deemed to have been effected only on personal delivery thereof to, or if sent by mail or other means of transmission on actual receipt thereof by, the Warrant Agent at its principal office as set out above.

Subject to adjustment thereof in the events and in the manner set forth in the Warrant Indenture hereinafter referred to, the exercise price payable for each Common Share upon the exercise of Warrants shall be US$3.00 per Common Share (the "Exercise Price").

A-3

Certificates for the Common Shares subscribed for will be mailed to the persons specified in the Exercise Form at their respective addresses specified therein or, if so specified in the Exercise Form, delivered to such persons at the office where this Warrant Certificate is surrendered. If fewer Common Shares are purchased than the number that can be purchased pursuant to this Warrant Certificate, the holder hereof will be entitled to receive without charge a new Warrant Certificate in respect of the balance of the Warrants not so exercised. No fractional Common Shares will be issued upon exercise of any Warrant.

This Warrant Certificate evidences Warrants of the Corporation issued or issuable under the provisions of a warrant indenture (which indenture, together with all other instruments supplemental or ancillary thereto, is herein referred to as the "Warrant Indenture") dated as of October 1, 2024 among the Corporation and TSX Trust Company, as Warrant Agent, to which Warrant Indenture reference is hereby made for particulars of the rights of the holders of Warrants, the Corporation and the Warrant Agent in respect thereof and the terms and conditions on which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder, by acceptance hereof, assents. The Corporation will furnish to the holder, on request and without charge, a copy of the Warrant Indenture.

Neither the Warrants nor the Common Shares issuable upon exercise hereof have been or will be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or U.S. state securities laws. The Warrants may not be exercised in the United States, or by or on behalf of, or for the account or benefit of, a U.S. person or a person in the United States, unless (i) this Warrant and such Common Shares have been registered under the U.S. Securities Act and the applicable laws of any such state, or (ii) an exemption from such registration requirements is available and the requirements set forth in the Exercise Form have been satisfied. "United States" and "U.S. person" are as defined in Regulation S under the U.S. Securities Act.

If this Warrant Certificate tendered for transfer bears the legend set forth in subsection 2.6(4) of the Warrant Indenture, the Warrant Agent shall not register such transfer unless the transferor has provided the Warrant Agent with this Warrant Certificate and the transfer is made: (i) to the Corporation, (ii) outside the United States, in accordance with Rule 904 of Regulation S under the U.S. Securities Act and in compliance with applicable local laws and regulations, (iii) pursuant to the exemptions from registration under the U.S. Securities Act provided by (1) Rule 144, if available, or (2) Rule 144A thereunder, if available, and in compliance with applicable state securities laws, or (iv) in another transaction that does not require registration under the U.S. Securities Act or any applicable state securities laws, provided that in the case of transfers pursuant to (iii)(1) or (iv) above, a legal opinion in form and substance reasonably satisfactory to the Corporation must first be provided to the Corporation's transfer agent; provided that (i) if this Warrant Certificate is transferred outside the United States in accordance with Rule 904 of Regulation S under the U.S. Securities Act, such legend may be removed by providing a declaration to the Warrant Agent in the form attached as Schedule "E" to the Warrant Indenture, or such form as the Corporation may from time to time prescribe, together with such documentation as the Warrant Agent may require.

On presentation at the principal office of the Warrant Agent as set out above, subject to the provisions of the Warrant Indenture and on compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged for one or more Warrant Certificates representing in the aggregate an equal number of Warrants as are held under the Warrant Certificate(s) so exchanged.

The Warrant Indenture contains provisions for the adjustment of the Exercise Price payable for each Common Share upon the exercise of Warrants and the number of Common Shares issuable upon the exercise of Warrants in the events and in the manner set forth therein.

A-4

The Warrant Indenture also contains provisions making binding on all holders of Warrants outstanding thereunder resolutions passed at meetings of holders of Warrants held in accordance with the provisions of the Warrant Indenture and instruments in writing signed by Warrantholders of Warrants holding a specific majority of the Warrants.

Nothing contained in this Warrant Certificate, the Warrant Indenture or elsewhere shall be construed as conferring upon the holder hereof any right or interest whatsoever as a holder of Common Shares or any other right or interest except as herein and in the Warrant Indenture expressly provided. In the event of any discrepancy between anything contained in this Warrant Certificate and the terms and conditions of the Warrant Indenture, the terms and conditions of the Warrant Indenture shall govern.

Warrants may only be transferred in compliance with the conditions of the Warrant Indenture on the register to be kept by the Warrant Agent in Toronto, or such other registrar as the Corporation, with the approval of the Warrant Agent, may appoint at such other place or places, if any, as may be designated, upon surrender of this Warrant Certificate to the Warrant Agent or other registrar accompanied by a written instrument of transfer in form and execution satisfactory to the Warrant Agent or other registrar and upon compliance with the conditions prescribed in the Warrant Indenture and with such reasonable requirements as the Warrant Agent or other registrar may prescribe and upon the transfer being duly noted thereon by the Warrant Agent or other registrar. Time is of the essence hereof.

This Warrant Certificate will not be valid for any purpose until it has been countersigned by or on behalf of the Warrant Agent from time to time under the Warrant Indenture.

The parties hereto have declared that they have required that these presents and all other documents related hereto be in the English language. Les parties aux présentes déclarent qu'elles ont exigé que la présente convention, de même que tous les documents s'y rapportant, soient rédigés en anglais.

Any capitalized term in this Warrant Certificate that is not otherwise defined herein, shall have the meaning ascribed thereto in the Warrant Indenture.
