(f) a Beneficial Warrantholder will have no direct rights as against the Corporation, who may treat the Depository as the sole Warrantholder.

the Warrant Agent, on notification by the Corporation, shall so notify the Depository and request that the Depository notify all Beneficial Warrantholders of the occurrence of any such event and of the availability to Beneficial Warrantholders of definitive warrant certificate(s). As soon as is reasonably practicable thereafter, upon the surrender by the Depository to the Warrant Agent of the Global Warrant Certificate(s) representing the Book-Entry Only Warrants, the Corporation shall execute and the Warrant Agent shall certify and issue through the Depository definitive Warrant certificate(s) in a form adopted by the Corporation and prepared in compliance with all applicable laws, register such certificates in the names of the

- 14 -

Warrantholders (or in such names as the Warrantholders may instruct) and deliver such certificates in accordance with the instructions of the Warrantholders and cause the names of such Warrantholders (or such other Persons as the Warrantholders have instructed) to be entered on the register. Upon the issuance of definitive Warrant certificate(s), the Corporation and the Warrant Agent shall recognize the registered holders of the definitive Warrant certificate(s) as Warrantholders.

ARTICLE 3

EXERCISE OF WARRANTS

Section 3.1 Exercise of Warrants by the Holder

(1) Subject to the terms hereof, including the provisions of Section 3.1, each holder of Warrants may exercise the right conferred on such holder to purchase one Common Share (subject to adjustment in accordance with the terms hereof) for each Warrant held by surrendering to the Warrant Agent at the Warrant Agency, after the Effective Date and prior to the Time of Expiry:

(a) the Warrant Certificate with a duly completed and executed Exercise Form in the form substantially set out in Schedule “A”; and

(b) a certified cheque, bank draft or money order in lawful money of Canada payable to or to the order of the Corporation at par in the city where such Warrant Certificate is surrendered in an amount equal to the Exercise Price multiplied by the number of Common Shares subscribed for.

A Warrant Certificate with the duly completed and executed Exercise Form referred to in Section 3.1(1)(a), together with the payment of the Exercise Price of the Common Shares subscribed for and referred to in Section 3.1(1)(b), shall be deemed to be surrendered only upon personal delivery thereof or, if sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the Warrant Agency.

(2) A Beneficial Warrantholder who desires to exercise his or her Warrants must do so by causing a Depository Participant to deliver to the Depository (at its office in the City of Toronto or the City of Calgary), on behalf of the Beneficial Warrantholder, a written notice of the owner’s intention to exercise Warrants. A beneficial owner who desires to exercise Warrants should ensure that the Depository Participant is provided with notice (the “Exercise Notice”) of his intention to exercise sufficiently in advance of the Time of Expiry so as to permit the Depository Participant to deliver notice to the Depository and so as to permit Depository to deliver notice to the Corporation by the required time. Any expense associated with the preparation and delivery of Exercise

- 15 -

Notices will be for the account of the beneficial owner exercising the subscription privilege.

(3) By causing a Depository Participant to deliver to the Depository a notice of the Beneficial Warrantholder’s intention to exercise Warrants, a Beneficial Warrantholder shall be deemed to have irrevocably surrendered his or her Warrants so exercised and appointed such Depository Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Common Shares in connection with the obligations arising from such exercise.

(4) Any Exercise 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 Depository Participant to exercise or to give effect to the settlement thereof in accordance with the beneficial owner’s instructions will not give rise to any obligations or liability on the part of the Corporation to the Depository Participant or the Beneficial Warrantholder.

(5) Notwithstanding any provision to the contrary contained in this Indenture, no U.S. Person or person holding a Warrant for the account of a U.S. Person shall exercise any Warrant pursuant to this Section 3.1 at any time when no Registration Statement is effective, provided that at any such time, any U.S. Person and any person holding a Warrant for the account or benefit of a U.S. Person shall be entitled to the rights and benefits set forth in Section 3.9 hereof. If no Registration Statement is effective at any time when a Warrant is exercised, as a condition to the exercise of any Warrant the Corporation may require that the holder of such Warrant provide such evidence as the Corporation shall reasonably request that such person is not a U.S. Person or person holding such Warrant for the account of a U.S. Person.

(6) Any Exercise Form referred to in Section 3.1(1) and any Notice of Intent to Exercise Form referred to in Section 3.9 shall be signed by the Warrantholder and shall specify:

(a) the number of Common Shares which the holder wishes to acquire (being not more than the number of Common Shares which the holder is entitled to acquire pursuant to the Warrant Certificate(s) surrendered);

(b) the person or persons in whose name or names such Common Shares are to be issued;

(c) the address or addresses of such person or persons; and

- 16 -

(d) the number of Common Shares to be issued to each such person if more than one is so specified.

Any Warrantholder in a jurisdiction other than Canada or the United States must ensure compliance with all applicable securities laws in such jurisdictions in connection with the issuance of Common Shares upon exercise of Warrants.

(7) Notwithstanding the foregoing, if any of the Common Shares subscribed for are to be issued to a person or persons other than the Warrantholder, the signature(s) set out in the Exercise Form or Notice of Intent to Exercise Form (as the case may be) shall be guaranteed by an Eligible Institution and the Warrantholder shall comply with such reasonable requirements as the Warrant Agent may prescribe. The duly completed and executed Transfer Form shall be completed along with the Exercise Form or Notice of Intent to Exercise Form (as the case may be).

Section 3.2 Transfer Fees and Taxes

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

Section 3.3 Warrant Agency

In connection with the exchange or transfer of Warrant Certificates and exercise of Warrants and compliance with such other terms and conditions hereof as may be required, the Corporation has appointed the principal office of the Warrant Agent in the city of Toronto, Ontario or Calgary, Alberta as the agency at which Warrant Certificates 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 and shall give notice to the Warrant Agent of any change of the Warrant Agency.

Section 3.4 Effect of Exercise of Warrants

(1) Upon the exercise of Warrants pursuant to Section 3.1 or upon the Determination Date (as defined below) pursuant to Section 3.9, as the case may be, and subject to Section 3.5, the Common Shares to be issued shall be deemed to have been issued and the person or persons to whom such

- 17 -

Common Shares are to be issued shall be deemed to have become the holder or holders of record of such Common Shares on the Exercise Date unless the transfer registers of the Corporation shall be closed on such date, in which case the Underlying Securities 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 transfer registers are reopened.

(2) The Corporation shall, upon receipt of the Warrant Certificate, the payment of the Exercise Price and the Exercise Form duly completed, as soon as practicable and in any event within five (5) Business Days after the Exercise Date, cause to be 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 for the appropriate number of Underlying Securities evidenced by the Warrant Certificate. In addition, if it is required by law, the Corporation shall cause to be delivered to any U.S. Person in whose name the Underlying Securities issuable upon exercise of the Warrants are to be issued a prospectus that complies with the U.S. Securities Act.

Section 3.5 Partial Exercise of Warrants; Fractions

(1) The holder of any Warrants may exercise his right to acquire Common Shares in part and may thereby acquire a number of Common Shares less than the aggregate number which such holder is entitled to acquire pursuant to the surrendered Warrant Certificate(s). 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 the Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate(s) in respect of the balance of the Warrants represented by the surrendered Warrant Certificate(s) and which were not then exercised.

(2) Notwithstanding anything herein contained, including any adjustment provided for in Article 4, the Corporation shall not be required, upon the exercise of any Warrants, to issue fractions of Underlying Securities or to distribute certificates or Warrants which evidence a fractional Underlying Security. In the event that a fractional share results upon the exercise of any Warrants, the issuance shall be rounded down to the nearest whole Common Share. If more than one Warrant shall be presented for exercise in full at the same time by the same Warrantholder, the number of Underlying Securities that shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Underlying Securities purchasable on exercise of the Warrants so presented.

- 18 -

Section 3.6 Expiration of Warrants

Immediately after the Time of Expiry, all rights under any Warrant in respect of which the right of acquisition herein and therein provided for shall not have been exercised shall cease and terminate and such Warrant shall be void and of no further force or effect except to the extent that the Warrantholder has not received certificates representing the Common Shares held by it, in which instances the Warrantholder’s rights hereunder shall continue until it has received that to which it is entitled hereunder.

Section 3.7 Accounting and Recording

(1) The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised. Any securities or other instruments (including any property), 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 in trust 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 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.

Section 3.8 Securities Restrictions

Notwithstanding any provision to the contrary contained in this Indenture, in relation to the issuance of Common Shares outside of Canada or the United States, no Common Shares will be issued pursuant to the exercise of any Warrant if the issuance of such securities would constitute a violation of the securities laws of any such jurisdiction, and, without limiting the generality of the foregoing, the Corporation will legend the certificates representing the Common Shares 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 such 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, at his 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 may thereafter be surrendered to the Corporation in exchange for a certificate which does not bear such legends. For greater certainty, should no Registration Statement be effective, the Corporation

- 19 -

shall permit, at the Corporation’s sole discretion, the cashless exercise or redemption of Warrants held by U.S. Persons as set forth in Section 3.9 and shall not be permitted to issue legended Underlying Securities in lieu thereof.

Section 3.9 Cashless Exercise or Redemption of Warrants by U.S. Persons

(1) If the Registration Statement ceases to be effective, prior to the Time of Expiry and for so long as the Registration Statement is not effective, any holder of any Warrant that is a U.S. Person may provide the Corporation with a notice of intent to exercise such Warrant by surrendering the certificate representing such Warrant at any time during such period to the Warrant Agent at the Warrant Agency, with a duly completed and executed notice of intent to exercise form in substantially the form attached hereto (“Notice of Intent to Exercise Form”), upon which the holder shall indicate that he or she is exercising his or her right to exercise the Warrants. Upon receipt of the Notice of Intent to Exercise Form, the Warrant Agent at the Warrant Agency shall inform the Corporation of the Warrantholder’s intent to exercise. Within three business days of notice from the Warrant Agent at the Warrant Agency of the provision of a Notice of Intent to Exercise Form, the Corporation shall (i) elect, at its sole discretion, to either (a) redeem the Warrants or (b) permit the cashless exercise of the Warrants, each as provided in this section, and (ii) deliver an officer’s certificate to the Warrant Agent of such election (the “Officer’s Certificate”), which election shall be irrevocable. As a condition of such cashless exercise or redemption, the Corporation may require that the holder of such Warrant provide such evidence that it is a U.S. Person as the Corporation shall reasonably request, provided that if the Corporation, acting reasonably, is not satisfied in such circumstance that such Warrantholder is a U.S. Person or person holding such Warrant for the account of a U.S. Person, such Warrantholder shall be notified forthwith by the Warrant Agent that such Warrantholder is entitled to exercise his or her Warrant, in whole or in part, in accordance with Section 3.1. If the holder exercises the right provided for in this Section 3.9(1) in respect of a lesser number of Warrants than the aggregate number of Warrants represented by the Warrant Certificate surrendered, the Warrantholder shall be entitled to receive a further Warrant Certificate in respect of the Warrants represented by the Warrant Certificates that have not been part of a cashless exercise or redeemed. The Corporation’s right to issue Common Shares upon the exercise of Warrants pursuant to this Section 3.9 shall be subject to the requirement that any such Common Shares not be subject to any restrictions on transfer in the United States or Canada.

(2) Forthwith following the election of the Corporation to permit the exercise by a Warrantholder of the cashless exercise or to redeem the Warrants in accordance with Section 3.9(1), the Warrant Agent shall deliver to the

- 20 -

Corporation a notice setting out the particulars of the Warrants to be exercised or redeemed and the name and address of the Warrantholder, the number of Common Shares to be issued, if a cashless exercise, or the amount of money to be paid pursuant to the redemption right (“Final Exercise Notice”).

(3) Within three Business Days of receipt of the Final Exercise Notice referred to in (2), the Corporation shall deliver an Officer’s Certificate to the Warrant Agent setting out the details of the Corporation’s decision whether to either (i) redeem the Warrants or (ii) permit the cashless exercise of the Warrants, each as provided in this section and the Corporation shall cause either (a) in the case of a redemption, a cheque in the amount of money determined by multiplying the number of Common Shares that would have been issued if the Warrants to be redeemed were exercised on the Determination Date (as defined below) by the excess (if any) of the Current Market Price per Common Share on the Determination Date over the Exercise Price or (b) in the case of a cashless exercise, a certificate representing the number of Common Shares equal to the number of Common Shares which would, but for such cashless exercise, have been issuable (“Total Share Number”) less the number of Common Shares equal to the quotient obtained by dividing (A) the product of the Total Share Number and Exercise Price by (B) the Current Market Price of the Common Shares on the Determination Date, to be mailed to such Warrantholder at the address specified in such Notice of Intent to Exercise Form, or, if so specified in such Notice of Intent to Exercise Form, to be made available for pick-up by such Warrantholder at the Warrant Agency.

(4) “Determination Date” means, with respect to any Warrants subject to the provisions of Section 5.1(h) hereof, the date the Warrant Certificate together with a duly completed and executed Notice of Intent to Exercise Form is surrendered to the Warrant Agent. A Warrant Certificate with the duly completed and executed Notice of Intent to Exercise Form shall be deemed to be surrendered upon personal delivery thereof, or if sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the Warrant Agency.

ARTICLE 4

ADJUSTMENT OF EXERCISE RIGHTS

Section 4.1 Adjustment of Exercise Rights

The Exercise Price per Common Share and the number of Common Shares or other property which may be subscribed for upon exercise of a Warrant shall be subject to adjustment from time to time upon the occurrence of any of the events and in the manner provided as follows:

- 21 -

(a) If and whenever at any time prior to the Time of Expiry the Corporation shall:

(i) issue, declare a dividend or make a distribution on its Common Shares in each case payable in Common Shares (or securities exchangeable for or convertible into Common Shares) at no additional cost to all or substantially all of the holders of Common Shares, or

(ii) subdivide, redivide or change its outstanding Common Shares into a greater number of Common Shares, or

(iii) reduce, combine or consolidate its outstanding Common Shares into a lesser number,

(any of such events in clauses 4.1(a)(i), (ii) and (iii) being called a “Share Reorganization”), then effective immediately after the record date or effective date, as the case may be, at which the holders of Common Shares are determined for the purposes of the Share Reorganization, the Exercise Price shall be adjusted to a price determined by multiplying the applicable Exercise Price in effect on 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 Share Reorganization and the denominator of which shall be the number of Common Shares outstanding immediately after giving effect to such Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of additional Common Shares that would have been outstanding had such securities been exchanged for or converted into Common Shares immediately after giving effect to such Share Reorganization).

(b) If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the issuing of rights, options or warrants to all or substantially all of the holders of the Common Shares entitling them for a period expiring not more than 45 days after such record date (the “Rights Period”) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for Common Shares) at a price per share (or having a conversion or exchange price per share) which is less than 95% of the Current Market Price per Common Share on the record date for such issue (any of such events being called a “Rights Offering”), then effective immediately after the end of the Rights Period the Exercise Price shall be adjusted to a price determined by multiplying the applicable Exercise Price in

- 22 -

effect at the end of the Rights Period by a fraction the numerator of which shall be the sum of:

(i) the number of Common Shares outstanding as of the record date for the Rights Offering, and

(ii) the number determined by dividing (A) either the product of (i) the number of Common Shares issued during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering and (ii) the price at which such Common Shares are issued, or, as the case may be, the product of (iii) the number of Common Shares for or into which the convertible or exchangeable securities issued during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering are exchangeable or convertible and (iv) the exchange or conversion price of the convertible or exchangeable securities so issued, by (B) the Current Market Price per Common Share as of the record date for the Rights Offering, and

the denominator of which shall be the number of Common Shares outstanding (including the number of Common Shares actually issued or subscribed for during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering) or which would be outstanding upon the conversion or exchange of all convertible or exchangeable securities issued during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering, as applicable, in each case after giving effect to the Rights Offering.

Common Shares owned by or held (otherwise than as security) for the account of the Corporation or any Subsidiary of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. In order to give effect to the provisions of Section 4.1(e) in the circumstances described below, any holder who shall have exercised his right to purchase Underlying Securities during the period beginning immediately after the record date for a Rights Offering and ending on the last day of the Rights Period therefor, in addition to the Underlying Securities to which he is otherwise entitled upon such exercise, shall be entitled to that number of additional Underlying Securities equal to the result obtained when the difference, if any, between the Exercise Price in effect immediately prior to the end of such Rights Offering and the Exercise Price as adjusted for such Rights Offering pursuant to this Section 4.1(b), is multiplied by the number of Common Shares purchased upon exercise of the Warrant held by such holder during such period, and the resulting product is divided by the

- 23 -

Exercise Price as adjusted for such Rights Offering pursuant to this Section 4.1(b). Such additional Common Shares shall be deemed to have been issued to the holder immediately following the end of the Rights Period and a certificate for such additional Common Shares shall be delivered to such holder within 10 Business Days following the end of the Rights Period.

(c) If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the payment, issue or distribution to all or substantially all of the holders of the Common Shares of (i) a dividend, (ii) cash or assets (including evidences of the Corporation’s indebtedness), or (iii) rights, options, warrants or other securities (including securities convertible into or exchangeable for Common Shares), and such payment, issue or distribution does not constitute a Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a “Special Distribution”), the Exercise Price shall be adjusted effective immediately after such record date to a price determined by multiplying the applicable Exercise Price in effect on such record date by a fraction:

(i) the numerator of which shall be:

(A) the product of the number of Common Shares outstanding on such record date and the Current Market Price per Common Share on such record date; less

(B) the fair market value, as determined in good faith by action of the directors (whose determination shall be conclusive), to the holders of the Common Shares of such cash, assets, rights, options, warrants or securities so paid, issued or distributed less the fair market value, as determined in good faith by action of the directors (whose determination shall be conclusive), of the consideration, if any, received therefor by the Corporation, and

(ii) the denominator of which shall be the number of Common Shares outstanding on such record date multiplied by the Current Market Price per Common Share on such record date.

Such adjustment shall be made successively whenever such a record date is fixed. To the extent that such payment, issuance or distribution is not so made, the Exercise Price shall be readjusted effective immediately to the Exercise Price which would then be in effect based upon such payment, issuance or distribution actually made.

- 24 -

(d) If and whenever at any time prior to the Time of Expiry there shall be a reorganization, reclassification or other change of Common Shares outstanding at such time or change of the Common Shares into other shares or into other securities (other than a Share Reorganization, a Rights Offering or a Special Distribution), or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other corporation or other entity (other than a consolidation, amalgamation, arrangement or merger which does not result in any reclassification of the outstanding Common Shares or a change of the Common Shares into other shares), or a sale, conveyance or transfer of the undertaking or assets of the Corporation as an entirety or

- 25 -

substantially as an entirety to another corporation or entity in which the holders of Common Shares are entitled to receive shares, other securities or property, including cash (other than transfers of the property or assets of the Corporation which do not result in any reclassification of the outstanding Common Shares or a change of the Common Shares into other shares) (any of such events being herein called a “Capital Reorganization”), any holder who exercises his right to subscribe for and purchase Common Shares pursuant to the exercise of Warrants after the effective date of such Capital Reorganization shall be entitled to receive, and shall accept for the same aggregate consideration in lieu of the number of Common Shares to which such holder was theretofore entitled upon such exercise, the aggregate number of shares, other securities or other property which such holder would have received as a result of such Capital Reorganization had he exercised his right to acquire Underlying Securities immediately prior to the effective date or record date, as the case may be, of the Capital Reorganization and had he been the registered holder of such Underlying Securities on such effective date or record date, as the case may be, subject to adjustment thereafter in accordance with provisions the same, or nearly as may be possible, as those contained in Section 4.1(b) and Section 4.1(c) hereof. If determined appropriate by the directors, acting in good faith, appropriate adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Section 4.1, with respect to the rights and interests thereafter of the holder of a Warrant to the end that the provisions set forth in this Section 4.1 shall thereafter correspondingly be made applicable as nearly as may be reasonably possible in relation to any shares, other securities or other property thereafter deliverable upon the exercise of the Warrant. Any such adjustment shall be made by and set forth in an agreement supplemental hereto approved by action of the directors, acting in good faith, and shall for all purposes be conclusively deemed to be an appropriate adjustment.

(e) If and whenever at any time prior to the Time of Expiry there shall occur a Share Reorganization, a Rights Offering, or a Special Distribution and any such event results in an adjustment to the Exercise Price pursuant to the provisions of this Section 4.1, the number of Common Shares purchasable upon the exercise of each Warrant (at the adjusted Exercise Price) shall be adjusted contemporaneously with the adjustment of the Exercise Price by multiplying the number of Common Shares theretofore purchasable on the exercise thereof by a fraction, the numerator of which shall be the applicable Exercise Price in effect immediately prior to such

- 26 -

adjustment and the denominator of which shall be the applicable Exercise Price resulting from such adjustment.

(f) In case the Corporation after the date of issue of the Warrants shall take any action affecting the Common Shares, other than action described in this Section 4.1, which in the opinion of the directors, acting reasonably, would materially adversely affect the rights of the Warrantholders, the Exercise Price or the number of Common Shares purchasable upon the exercise of each Warrant shall be adjusted in such manner, if any, and at such time, by action of the directors, acting reasonably, as they may determine to be equitable in the circumstances, but subject in all cases to any necessary regulatory approvals.

Section 4.2 Adjustment Rules

For the purposes of Section 4.1, any adjustment shall be made successively whenever an event referred to therein shall occur, subject to the following provisions:

(a) all calculations shall be made to the nearest 1/100th of a Common Share;

(b) no adjustment to an Exercise Price shall be required unless such adjustment would result in a change of at least one per cent in the prevailing Exercise Price and no adjustment shall be made in the number of Common Shares which may be subscribed for upon exercise of the Warrant unless it would require a change of at least 1/100th of a Common Share; provided, however, that any adjustments which, except for the provisions of this Section 4.2(b) would otherwise have been required to be made shall be carried forward and taken into account in any subsequent adjustment;

(c) if any question shall arise with respect to adjustments provided for in this Article 4, such question shall, absent manifest error, be conclusively determined by a firm of chartered accountants appointed by the Corporation (who may be the Corporation’s Auditors) and acceptable to the Warrant Agent, acting reasonably; such chartered accountants shall have access to all necessary records of the Corporation and such determination shall be binding on the Corporation, the Warrant Agent and the Warrantholders, absent manifest error. In the event that any such determination is made, the Corporation shall deliver a certificate to the Warrant Agent describing such determination and confirming such consent;

- 27 -

(d) if the Corporation shall set a record date to determine the holders of its Common Shares for the purpose of entitling them to receive any dividend or distribution or any subscription or purchase rights, options or warrants and shall thereafter and before the distribution to such Shareholders of any such dividend, distribution or subscription or purchase rights legally abandon its plan to pay or deliver such dividend, distribution or subscription or purchase rights, then no adjustment in the Exercise Price or the number of Common Shares purchasable upon exercise of the Warrant shall be required by reason of the setting of such record date; and

(e) as a condition precedent to the taking of any action which would require any adjustment in any of the subscription rights pursuant to any of the Warrants, the Corporation shall take any corporate action which may, in the opinion of Counsel, 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 of the Underlying Securities that the Warrantholders are entitled to receive on full exercise thereof in accordance with the provisions hereof.

Section 4.3 Postponement of Subscription

In any case where the application of Section 4.1 results in an increase in the number of Underlying Securities taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior to completion of the event, the Corporation may postpone the issuance to the holder of the Warrant of the Common Shares to which such Warrantholder is entitled by reason of such adjustment but such Common Shares shall be so issued and delivered to that holder upon completion of that event, with the number of such Common Shares calculated on the basis of the number of Common Shares on the date that the Warrant was adjusted for completion of that event and the Corporation shall deliver to the person or persons in whose name or names the Common Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive such Common Shares and the right to receive any dividends or other distributions which, but for the provisions of this Section 4.3, such person or persons would have been entitled to receive in respect of such Common Shares from and after the date that the Warrant was exercised in respect thereof.

Section 4.4 Notice of Adjustment of Exercise Rights

(a) At least 14 days prior to the effective date or record date, as the case may be, of any event that requires or that may require an adjustment in any of the exercise rights pursuant to any of the Warrants, including

- 28 -

the number of Underlying Securities that may be acquired upon the exercise thereof, the Corporation shall:

(i) file with the Warrant Agent a certificate of the Corporation specifying the particulars of such event (including the record date or the effective date for such event) and, if determinable, the required adjustment and the computation of such adjustment; and

(ii) give notice to the Warrantholders of the particulars of such event (including the record date or the effective date for such event) and, if determinable, the required adjustment, in accordance with the provisions set out in Section 10.2.

(b) In case any adjustment for which a notice in Section 4.4(a) has been given is not then determinable, the Corporation shall promptly after such adjustment is determinable:

(i) file a certificate of the Corporation with the Warrant Agent showing how such adjustment was computed; and

(ii) give notice to the Warrantholders of the adjustment, in accordance with the provisions set out in Section 10.2.

(c) The Warrant Agent may act and rely for all purposes upon any certificates and any other documents filed by the Corporation pursuant to this Section 4.4.

Section 4.5 No Action after Notice

The Corporation shall not take any other corporate action that might deprive any Warrantholder of the opportunity to exercise Warrants during the 14-day period after the giving of the notice set forth in Section 4.4(a).

Section 4.6 No Duty to Inquire

The Warrant Agent shall not at any time be under any duty or responsibility to any Warrantholder to determine whether any facts exist which may require any adjustment contemplated by Section 4.1 and Section 4.2, 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. The Warrant Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant.

Section 4.7 Rights Issued in Respect of Underlying Securities on Exercise

Each Common Share issued on the exercise of Warrants shall be entitled to receive the appropriate number of purchase rights (“Rights”), if any, that all

- 29 -

Common Shares are entitled to receive, and the certificates representing such Common Shares shall bear such legends, if any, in each case as may be provided by the terms of any shareholder rights agreement adopted by the Corporation, as the same may be amended from time to time (a “Rights Agreement”); provided that such Rights Agreement requires that each Common Share issued on exercise of Warrants at any time prior to the distribution of separate certificates representing the Rights be entitled to receive such Rights, then, not withstanding anything else to the contrary in this Indenture, there shall not be any adjustment made pursuant to this Article 4 as a result of the issuance of Rights, the distribution of separate certificates representing the Rights, the exercise or redemption of such Rights in accordance with any such Rights Agreement, or the termination or invalidation of such Rights.

Section 4.8 Determination Date

For the purposes of Article 4, the Determination Date for any Warrant shall be the date such Warrant was exercised.

ARTICLE 5

RIGHTS OF THE CORPORATION AND COVENANTS

Section 5.1 General Covenants

The Corporation covenants with the Warrant Agent that so long as any Warrants remain outstanding:

upon being indemnified to its reasonable satisfaction by the Corporation or by the Warrantholders signing such Warrantholders’ Request against the cost which may be incurred in connection with the calling and holding of such meeting, convene a meeting of the Warrantholders. In the event of the Warrant Agent failing to so convene a meeting within ten (10) days after receipt of such written request of the Corporation or such Warrantholders’ Request and indemnity given as aforesaid, the Corporation or such Warrantholders, as the case may be, may convene such meeting.

At least twenty-one calendar days prior notice of any meeting of Warrantholders shall be given to the Warrantholders in the manner provided for in Section 10.2 and a copy of such notice shall be sent by mail to the Warrant Agent (unless the meeting has been called by the Warrant Agent) and to the Corporation (unless the meeting has been called by the Corporation). 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 Article 7.

Section 7.3 Chairman

An individual (who need not be a Warrantholder) designated in writing by the Warrant Agent shall be chairman of any meeting of Warrantholders and if no individual is so designated, or if the individual so designated is not present within 15 minutes from the time fixed for the holding of the meeting, the Warrantholders present in person or by proxy shall choose some individual present to be chairman.

- 35 -

be given. Any business may be brought before or dealt with at an adjourned meeting which might have been dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless a quorum be present at the commencement of business. 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, notwithstanding that they may not be entitled to acquire at least 25% of the aggregate number of Common Shares which may be acquired pursuant to all then outstanding Warrants.

A proxy need not be a Warrantholder. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Warrants, if any, held or represented by him.

(e) the form of the instrument of proxy; and

(f) generally for the calling of meetings of Warrantholders and the conduct of business thereat.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted.

(c) the Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof;

- 45 -

(4) Any corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Warrant Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Warrant Agent shall be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under Section 9.8(1).

(5) Any Warrant Certificates certified but not delivered by a predecessor Warrant Agent may be certified by the successor Warrant Agent in the name of the predecessor or successor Warrant Agent.

- 47 -

approved by the Corporation and meeting the requirements set forth in Section 9.8(1). Notwithstanding the foregoing provisions of this Section 9.1(1), if any such material conflict of interest exists or hereafter shall exist, the validity and enforceability of this Indenture and the Warrant Certificate shall not be affected in any manner whatsoever by reason thereof.

The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to lack of information or for any other reason whatsoever, the Warrant Agent, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Warrant Agent, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on thirty (30) days written notice to the Corporation, provided that (a) the Warrant Agent’s written notice shall describe the circumstances of such non-compliance; and (b) if such circumstances are rectified to the Warrant Agent’s satisfaction within such ten (10) day period, then such resignation shall not be effective.

Section 9.13 Accounts Opened for Corporation

The Corporation hereby represents to the Warrant Agent that any account to be opened by, or interest to be held by, the Warrant Agent in connection with this Indenture, for or to the credit of the Corporation, either (a) is not intended to be used by or on behalf of any third party; or (b) is intended to be used by or on behalf of a third party, in which case the Corporation hereto agrees to complete and execute forthwith a declaration in the Warrant Agent’s prescribed form as to the particulars of such third party.

THIS IS SCHEDULE “A” to the Warrant Indenture made as of September [25], 2009 between Compton Petroleum Corporation and Computershare Trust Company of Canada, as Warrant Agent.

WARRANT CERTIFICATE

COMPTON PETROLEUM CORPORATION

(Incorporated under the laws of the Province of Alberta)

CUSIP 204940118

WARRANT CERTIFICATE NO.                                                                   WARRANTS entitling the holder to acquire, subject to adjustment, one (1) Common Share for each Warrant represented hereby.

THIS IS TO CERTIFY THAT,                                                      , for value received (hereinafter referred to as the “holder”), subject to the terms, covenants, conditions and provisions of that Warrant Indenture between Compton Petroleum Corporation (the “Corporation”) and Computershare Trust Company of Canada (the “Warrant Agent”), dated September [25], 2009 (the “Indenture”), is entitled at any time prior to 5:00 p.m. (Calgary time) on September [25], 2011 (the “Time of Expiry”) to acquire in the manner and subject to the restrictions and adjustments set forth herein, one (1) fully paid and non-assessable common share (“Common Share”) of the Corporation, as such shares were constituted on the Effective Date, upon payment of C$1.55 per share payable to the Corporation by way of a certified cheque, money order or bank draft. Any Warrants not exercised prior to the Time of Expiry shall be void and of no effect. Any terms utilized herein and not otherwise defined shall have the meanings ascribed thereto in the Indenture.

The certificates representing the Common Shares issued may be obtained upon duly completing and executing the Exercise Form attached hereto and surrendering this Warrant Certificate to the Warrant Agent at the principal office of the Warrant Agent in the city of Toronto, Ontario or the city of Calgary, Alberta (or such alternate place or additional place as may be designated from time to time), together with a certified cheque, bank draft or money order payable to the Corporation for the applicable Exercise Price. These Warrants shall be deemed to be surrendered only upon personal delivery hereof or, if sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above, unless the Corporation accepts another form of delivery.

Upon surrender of these Warrants, the person or persons in whose name or names the Common Shares issuable upon exercise of the Warrants are to be issued

- 2 -

shall be deemed for all purposes (except as provided in the Indenture) to be the holder or holders of record of such Common Shares and the Corporation has covenanted that it will (subject to the provisions of the Indenture) as soon as practicable and in any event within five (5) Business Days after the Exercise Date cause a certificate or certificates representing such Common Shares to be delivered to the Warrant Agency or to be mailed to the person or persons at the address or addresses specified in the Exercise Form.

The registered holder of these Warrants may only acquire that number of Common Shares that is equal to the number of Common Shares which may be acquired for the Warrants represented by this Warrant Certificate. The registered holder of these Warrants may acquire any lesser number of Common Shares than the total number of Common Shares that may be acquired upon the exercise of the Warrants represented by this Warrant Certificate. In such event, the holder shall be entitled to receive a new Warrant Certificate for the balance of the Common Shares which may be acquired. No fractional Common Shares will be issued.

The Indenture provides for adjustments to the right of exercise, including the amount of and class and kind of securities or other property issuable upon exercise, upon the happening of certain stated events, including the subdivision or consolidation of the Common Shares, certain distributions of Common Shares or securities convertible into Common Shares or of other securities or assets of the Corporation, certain offerings of rights, warrants or options and certain reorganizations.

The Warrants represented by this certificate are issued under and pursuant to the Indenture between the Corporation and the Warrant Agent. Reference is made to the Indenture and any instruments supplemental thereto for a full description of the rights of the holders of the Warrants and the terms and conditions upon which the Warrants are, or are to be, issued and held, with the same effect as if the provisions of the Indenture and all instruments supplemental thereto were herein set forth. By acceptance hereof, the holder assents to all provisions of the Indenture. A copy of the Indenture will be provided at no cost to a holder who makes a request for such copy to the Corporation. IF ANY CONFLICT EXISTS BETWEEN THE PROVISIONS CONTAINED HEREIN AND THE PROVISIONS OF THE INDENTURE, THE PROVISIONS OF THE INDENTURE SHALL GOVERN.

The Warrants evidenced hereby shall not be exercised by any person in the United States or any “U.S. person” (a “U.S. Person”) as defined in Rule 902(k) of Regulation S under the U.S. Securities Act or any person holding such Warrants for the account or benefit of a U.S. Person or persons in the United States during any time that no registration statement under the U.S. Securities Act registering the Common Shares issuable upon the exercise of the Warrants evidenced hereby is effective, unless an exemption from the registration requirements to the U.S.

- 3 -

Securities Act is available and such holder provides evidence of the availability of such exemption satisfactory to the Corporation and the Warrant Agent. During such time and prior to the Time of Expiry, any U.S. Person holding such Warrants shall have the right to provide notice to the Corporation of their intent to exercise, at which time the Corporation shall, at its own discretion, permit such holder to exercise on a cashless basis such Warrant (provided that the Common Shares issued pursuant to such cashless exercise shall not be subject to any transfer restrictions in the United States or Canada) or redeem such Warrants in accordance with the terms of the Indenture.

The holder of this Warrant Certificate may, at any time prior to the Time of Expiry, upon surrender hereof to the Warrant Agent at its principal office in the city of Toronto, Ontario or the city of Calgary, Alberta (or such alternate place or additional place as may be designated from time to time), exchange this Warrant Certificate for other Warrant Certificates entitling the holder to acquire, in the aggregate, the same number of Common Shares as may be acquired under this Warrant Certificate.

The holding of the Warrants evidenced by this Warrant Certificate shall not constitute the holder hereof a shareholder of the Corporation or entitle the holder to any right or interest in respect thereof except as expressly provided in the Indenture and in this Warrant Certificate.

The Indenture provides that all holders of Warrants shall be bound by any resolution passed at a meeting of the holders of Warrants held in accordance with the provisions of the Indenture and resolutions signed by the holders of Warrants entitled to acquire a specified majority of the Common Shares which may be acquired pursuant to all then outstanding Warrants.

The Warrants evidenced by this Warrant Certificate may be transferred on the register kept at the office of the Warrant Agent by the registered holder hereof or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent, upon compliance with the conditions prescribed in the Indenture including the execution of the Transfer Form attached to this Warrant Certificate and all applicable laws and upon compliance with such reasonable requirements as the Warrant Agent may prescribe.

This Warrant Certificate shall not be valid for any purpose whatever unless and until it has been certified by or on behalf of the Warrant Agent.

The parties hereto have expressly requested that this Warrant Certificate, all documents attached hereto, any notices or other documents to be given under this Warrant Certificate, and other documents related thereto be drawn up in the English language. Les parties aux présentes ont expressément exigé que le présent certificat de bons de souscription et tous les documents qui y sont affixés à ledit certificat de

bons de souscription, ainsi que tout avis donné en vertu dudit certificat de bons de souscription ou tout autre document qui s’y rapporte, soient rédigés en anglais.

The Indenture and this Warrant Certificate shall be governed by and construed in accordance with the laws of the Province of Alberta. Notwithstanding the preceding sentence, the exercise, performance or discharge by the Warrant Agent of any of its rights, powers, duties or responsibilities under the Indenture shall be construed in accordance with the laws of the Province of Ontario and the Federal laws of Canada applicable therein. Time shall be of the essence hereof.
