the Warrantholder has executed and delivered to the Trustee a declaration in the form attached as Schedule B hereto (or as the Corporation may otherwise prescribe) to the effect that the transfer is being made pursuant to Rule 904 of Regulation S under the 1933 Act, and in such case the Warrant Certificate issued to the transferee shall not include the legend set forth in Section 2.10 unless the Corporation has, prior to the issuance thereof, informed the Trustee that it has ceased to be a “foreign issuer” as defined in Rule 902 under the 1933 Act; or

(ii)

the Warrantholder has delivered to the Trustee and the Corporation an opinion of counsel to the effect that the transfer is in compliance with the requirements of the 1933 Act and all applicable state securities laws, and the Corporation has confirmed in writing to the Trustee that such opinion is satisfactory to the Corporation, and in such case the Warrant Certificate issued to the transferee shall include the legend set forth in Section 2.11 unless such opinion states that the legend is no longer required; or

- 9 -

PROVIDED THAT THE CORPORATION IS A “FOREIGN ISSUER” WITHIN THE MEANING OF REGULATION S AT THE TIME OF SALE AND THESE SECURITIES ARE BEING SOLD IN COMPLIANCE WITH RULE 904 OF REGULATION S, A NEW CERTIFICATE BEARING NO LEGEND MAY BE OBTAINED FROM COMPUTERSHARE TRUST COMPANY OF CANADA, AS REGISTRAR AND TRANSFER AGENT, UPON DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED DECLARATION, IN A FORM SATISFACTORY TO COMPUTERSHARE TRUST COMPANY OF CANADA AND THE CORPORATION, TO THE EFFECT THAT SUCH SALE IS BEING MADE IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT;

The transferee of a Warrant shall, after the transfer form attached to the Warrant Certificate is duly completed and the Warrant Certificate and form of transfer are lodged with the Trustee, and upon compliance with all other conditions in that regard required by this Indenture and by all applicable securities legislation and requirements of regulatory authorities, be entitled to have his name entered on the register as the owner of such Warrant free from all equities or rights of set-off or counterclaim between the Corporation and his transferor or any previous Warrantholder of such Warrant, save in respect of equities of which the Corporation or the transferee is required to take notice by statute or by order of a court of competent jurisdiction.

2.15

Registers Open for Inspection

The registers hereinbefore referred to shall be open at the office of the Trustee during normal business hours on each Business Day and upon reasonable written notice for inspection by the Corporation, the Trustee or any Warrantholder. The Trustee shall, from time to time when requested to do so by the Corporation, furnish the Corporation with a list of the names and

- 12 -

addresses of Warrantholders entered in the register kept by the Trustee showing the number of Warrants and the number of Common Shares which may then be acquired upon the exercise of the Warrants held by each such Warrantholder.

2.16

Ownership of Warrants

(a)

The Corporation and the Trustee may deem and treat the registered Warrantholder of any Warrant Certificate as the absolute owner of the Warrant represented thereby for all purposes, and the Corporation and the Trustee shall not be affected by any notice or knowledge to the contrary, except where the Corporation or the Trustee is required to take notice by statute or by order of a court of competent jurisdiction. For greater certainty, subject to applicable law, neither the Corporation nor the Trustee will be bound to take notice of or see to the execution of any trust, whether express, implied or constructive, in respect of any Warrant, and may transfer any Warrant on the direction of the person registered as Warrantholder thereof, whether named as trustee or otherwise, as though that person were the beneficial owner thereof.

(b)

Subject to the provisions of this Indenture and applicable law, each Warrantholder shall be entitled to the rights and privileges attaching to the Warrants held thereby. The exercise of the Warrants in accordance with the terms hereof and the receipt by any such Warrantholder of Common Shares pursuant thereto shall be a good discharge to the Corporation and the Trustee with respect to such Warrants and neither the Corporation nor the Trustee shall be bound to inquire into the title of any such holder.

ARTICLE 3

Exercise of Warrants

3.1

Method of Exercise of Warrants

(a)

Subject to Section 3.9, the holder of any Warrant may exercise the right evidenced thereby conferred on such holder to acquire Common Shares by surrendering, prior to the Time of Expiry, to the Trustee at a Warrant Agency:

(i)

the Warrant Certificate representing such Warrant, with a duly completed and executed exercise form in the form attached to the Warrant Certificate; and

(ii)

a certified cheque or bank draft payable to or to the order of the Corporation (or payment in such other form as the Trustee may accept), in the amount of the aggregate Exercise Price of such Warrants being exercised.

A Warrant Certificate with the duly completed and executed exercise form referred to in this subsection 3.1(a) 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 at, in each case, a Warrant Agency or such other place or

- 13 -

places that may be designated by the Corporation with the approval of the Trustee, provided that such Warrant Certificate is accompanied by the requisite payment of the aggregate Exercise Price for the Warrants represented thereby that are being exercised.

(b)

Any exercise form referred to in subsection 3.1(a) shall be signed by the Warrantholder or his executors, administrators or other legal representatives or his attorney duly appointed (such persons being obligated to provide the Trustee at the Warrant Agency with proof satisfactory to the Trustee of his or her authority to act on behalf of the Warrantholder) and shall specify:

(i)

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

(ii)

the person or persons in whose name or names such Common Shares are to be issued, and if such persons are individuals, the relevant social insurance numbers;

(iii)

the address or addresses of such person or persons;

(iv)

the number of Common Shares to be issued to each such person if more than one is so specified; and

(v)

that the Warrantholder represents, warrants and certifies as set forth in one of box A, box B or box C of the exercise form.

If any of the Common Shares subscribed for are to be issued to a person or persons other than the Warrantholder, the Warrantholder shall pay to the Corporation or the Trustee 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 Trustee 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 none is due.

(c)

In connection with the exchange 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 Trustee in each of Calgary and Toronto as an agency at which Warrant Certificates may be surrendered for exchange or at which Warrants may be exercised and the Trustee has accepted such appointment. The Corporation shall give notice to the Trustee of any change of the Warrant Agency.

3.2

Effect of Exercise of Warrants

(a)

Upon compliance by the holder of any Warrant Certificate with the provisions of Section 3.1, and subject to Section 3.3, the Common Shares subscribed for shall

- 14 -

be deemed to have been issued as fully paid and non-assessable 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 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 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 transfer registers are reopened.

(b)

Within five Business Days after the Exercise Date of a Warrant as set forth above, the Corporation shall cause to be mailed to the person or persons in whose name or names the Common Shares so subscribed for have been issued, as specified in the exercise form completed in connection with the exercise of the Warrants, at the address specified in such exercise form or, if so specified in such exercise form, 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 Common Shares subscribed for.

3.3

Partial Exercise of Warrants; Fractions

(a)

The holder of any Warrants may acquire a number of Common Shares less than the number which the 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 exercise thereof shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate(s) in respect of the balance of the Warrants which such holder was entitled to exercise pursuant to the surrendered Warrant Certificate(s) and which were not then exercised.

(b)

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 Common Shares or to distribute certificates which evidence fractional Common Shares. In lieu of fractional Common Shares, the Corporation shall pay to the holder who would otherwise be entitled to receive fractional Common Shares upon an exercise of Warrants, within 10 Business Days after the date upon which the fractional Common Shares would have been issued, an amount in lawful money of Canada equal to the Current Market Price of the Common Shares as of the Exercise Date multiplied by an amount equal to the fractional interest of Common Shares such holder would otherwise be entitled to receive upon such exercise, provided that the Corporation shall not be required to make any payment, calculated as aforesaid, that is less than $10.00. The price to be paid shall be provided by the Corporation in writing to the Trustee upon request.

3.4

Acceleration of Expiry Date

(a)

In the event the volume weighted average closing price of the Corporation’s Common Shares on the Toronto Stock Exchange is US$1.40 per share or more for

- 15 -

a period of 20 consecutive Trading Days at any time during the last 20 months of the original term of the Warrants, the board of directors of the Corporation may elect, by providing a written notice of the Corporation to the Warrantholders at their last known addresses on the records of the Corporation, to accelerate the expiry date for the exercise of all unexercised Warrants.

(b)

The Warrants will expire and cease to be exerciseable at the Time of Expiry on the date which is 30 calendar days after the date of mailing or other transmission of such notice by the Corporation to the Warrantholders in accordance with Section 10.2, provided that such notice is sent at least four months following the Issue Date.

(c)

For certainty, Warrantholders exercising unexercised Warrants pursuant to this Section 3.4 must do so in compliance with Section 3.1 and the provisions of Section 3 apply mutatis mutandis.

3.5

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.

3.6

Cancellation of Surrendered Warrants

All Warrant Certificates surrendered to the Trustee pursuant to Sections 2.7, 2.8, 2.9, 3.1, 3.3 and 5.1 shall be cancelled by the Trustee and, after the expiry of any period of retention prescribed by law, destroyed by the Trustee and, upon written request by the Corporation, the Trustee shall furnish to the Corporation a destruction certificate identifying the Warrant Certificates so destroyed, the number of Warrants evidenced thereby and the number of Common Shares which could have been purchased pursuant thereto.

3.7

Accounting and Recording

(a)

The Trustee shall as soon as reasonably practicable account to the Corporation with respect to Warrants exercised. Any monies, securities or other instruments, from time to time received by the Trustee shall be received in trust for and shall be segregated and kept apart by the Trustee in trust for the Corporation.

(b)

The Trustee shall record the particulars of Warrants exercised which shall include the names and addresses of the persons who become holders of Common Shares on exercise and the Exercise Date. Within five Business Days of each Exercise Date, the Trustee shall provide such particulars in writing to the Corporation.

3.8

Common Share Certificates

At the instruction of the Corporation, Common Shares issued in connection with the exercise of the Warrants may bear such legends as may be required by applicable securities regulatory requirements, authorities or stock exchanges, including, without limitation, the Toronto Stock Exchange.

- 16 -

3.9

Prohibition on Exercise by U.S. Persons; Exception

(a)

Warrants may not be exercised in the United States or by or on behalf of a U.S. Person unless the offer of Common Shares pursuant to the Warrants is registered under the 1933 Act or an exemption is available from the registration requirements of the 1933 Act and applicable state securities laws;

(b)

Any holder which exercises a Warrant shall provide to the Corporation and the Trustee, and the Corporation and the Trustee shall be entitled to act and rely thereon, either:

(i)

a written certification that such holder (i) at the time of exercise of the Warrant is not in the United States; (ii) is not a U.S. Person and is not exercising the Warrant, on behalf of a U.S. Person; and (iii) did not execute or deliver the exercise form for the Warrant in the United States;

(ii)

a written certification that such holder (i) originally purchased the Warrant on its own behalf or on behalf of a beneficial purchaser (a “Beneficial Purchaser”), directly from the Corporation pursuant to the Corporation’s offering of Units at a time when the holder was and any Beneficial Purchaser was an accredited investor, as defined in Rule 501(a) under the 1933 Act (“Accredited Investor”); (ii) is exercising the Warrant solely for its own account or for the account of the Beneficial Purchaser, if any, and not on behalf of any other person; and (iii) is, and the Beneficial Purchaser, if any, is, an Accredited Investor on the date of exercise of the Warrant; or

(iii)

a written opinion of counsel of recognized standing in form and substance satisfactory to the Corporation to the effect that an exemption from the registration requirements of the 1933 Act and applicable state securities laws is available for the issuance of the Common Shares issuable on exercise of the Warrants.

(c)

No certificates representing Common Shares will be registered or delivered to an address in the United States unless the holder of Warrants complies with the requirements set forth in subsection 3.9(b)(ii) or subsection 3.9(b)(iii) and, in the case of subsection 3.9(b)(iii), the Corporation has confirmed in writing to the Trustee that the opinion of counsel is satisfactory to the Corporation.

ARTICLE 4

Adjustment of Number of Common Shares

4.1

Adjustment of Number of Common Shares

The acquisition rights as they relate to Common Shares, attaching to the Warrants in effect at any date, and the Exercise Price in respect thereof, shall be subject to adjustment from time to time as follows:

(a)

If and whenever at any time during the Adjustment Period, the Corporation shall:

(i)

subdivide, redivide or change outstanding Common Shares into a greater number of shares,

(ii)

reduce, combine or consolidate the outstanding Common Shares into a smaller number of shares, or

(iii)

issue Common Shares or securities exchangeable for or convertible into Common Shares at no additional cost to the holders of all or substantially all of the outstanding Common Shares by way of a stock dividend or other distribution (other than the issue of Common Shares to holders of Common Shares pursuant to their exercise of options to receive dividends in the form of Common Shares in lieu of Dividends Paid in the Ordinary Course on the Common Shares),

(any of such events in these clauses (i), (ii) and (iii) being called a “Common Share Reorganization”), then effective immediately after the record date at which the holders of Common Shares are determined for the purposes of the Common Share Reorganization, the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of Common Shares outstanding on such record date before giving effect to such Common Share Reorganization and the denominator of which shall be the number of Common Shares outstanding after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares at no additional cost 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). Upon any adjustment to the Exercise Price pursuant to subsection 4.1(a), the number of Common Shares subject to the right of purchase under each Warrant shall be contemporaneously adjusted by multiplying the number of Common Shares which theretofore may have been purchased under such Warrant by a fraction of which the numerator shall be the respective Exercise Price in effect immediately prior to such adjustment and the denominator shall be the respective Exercise Price resulting from such adjustment.

(b)

If and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the issuance of rights, options or warrants to all or

- 18 -

substantially all the holders of its outstanding Common Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares (or securities convertible or exchangeable into Common Shares) at a price per share (or having a conversion or exchange price per share) less than 95% of the Current Market Price of a Common Share on such record date, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount 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 a number of Common Shares equal to the number arrived at 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 such 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; any Common Shares owned by or held for the account of the Corporation or any Subsidiary shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon the number of Common Shares (or securities convertible or exchangeable into Common Shares) actually issued upon the exercise of such rights, options or warrants, as the case may be.

(c)

If and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding Common Shares of (i) securities of any class, whether of the Corporation or any other person (other than Common Shares and other than securities distributed to holders of Common Shares pursuant to their exercise of options to receive dividends in the form of such securities in lieu of Dividends Paid in the Ordinary Course on the Common Shares), (ii) rights, options or warrants (excluding those referred to in subsection 4.1(b)), (iii) evidences of its indebtedness or (iv) assets (excluding Dividends Paid in the Ordinary Course) then, in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price 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 of a Common Share on such record date, less the aggregate fair market value (as determined by the directors, which determination shall be conclusive) of such securities shares, rights, options, warrants, evidences of indebtedness or assets so distributed, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by such Current Market Price; any Common Shares owned by or held for the account of the Corporation or any Subsidiary shall be deemed

- 19 -

not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that such distribution is not so 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 or to the Exercise Price which would then be in effect based upon such shares or rights, options or warrants or evidences of indebtedness or assets actually is distributed, as the case may be; in clause (iv) of this subsection 4.1(c) the term Dividends Paid in the Ordinary Course shall include the value of any securities or other property or assets distributed in lieu of cash Dividends Paid in the Ordinary Course at the option of Shareholders.

(d)

If and whenever at any time during the Adjustment Period, there is a reclassification of the Common Shares or a capital reorganization of the Corporation (other than as described in subsection 4.1(a)) or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity or a liquidation, dissolution or winding up of the Corporation (any of such events being hereinafter called a “Capital Reorganization”), any 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 and shall accept, in lieu of the number of Common Shares then sought to be acquired by it, 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, or to which such sale or conveyance may be made, as the case may be, that such Warrantholder would have been entitled to receive on such Capital Reorganization, if, on the record date or the effective date thereof, as the case may be, the Warrantholder had been the registered holder of the number of Common Shares sought to be acquired by it and to which it was entitled to acquire upon exercise of the Warrants. If determined appropriate by the Trustee to give effect to or to evidence the provisions of this subsection 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 Warrantholder is entitled on exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Trustee pursuant to the provisions of this subsection 4.1(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 8. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Trustee 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 Capital Reorganizations.

- 20 -

(e)

Notwithstanding any other provision of this Indenture, in the event of a Corporate Transaction, each Warrant will terminate immediately prior to the specified effective date of the Corporate Transaction, unless the Warrant is assumed by the successor corporation (or person) or its parent corporation (or person) in connection with the Corporate Transaction. Upon approval of a Corporate Transaction by the directors of the Corporation, the Corporation will give notice to each Warrantholder which will set forth terms that permit a Warrantholder to exercise its Warrants on a basis that provides the Warrantholder with the ability to participate in the Corporate Transaction or, failing completion of the Corporate Transaction, to retain all rights under the Warrants in accordance with the terms of this Indenture. A copy of such notice shall be sent to the Warrant Trustee.

(f)

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 holder of any Warrant exercised after such record date and before the occurrence of such event the additional Common Shares or other securities or property issuable upon such exercise by reason of the adjustment required by such event; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional Common Shares or other securities or property upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares or other securities or property declared in favour of holders of record of Common Shares or such other securities or property on and after the relevant date of exercise or such later date as such holder would, but for the provisions of this subsection 4.1(f), have become the holder of record of such additional Common Shares or other securities or property pursuant to subsection 4.1(b).

(g)

In any case in which subsections 4.1(a), 4.1(b) or 4.1(c) require that an adjustment be made to the Exercise Price, no such adjustment shall be made if, subject to the prior approval of the Toronto Stock Exchange (or other stock exchange or trading system on which the Common Shares or Warrants are listed for trading), the holders of the outstanding Warrants receive the Common Shares or securities exchangeable for or convertible into Common Shares referred to in subsection 4.1(a), the rights, options or warrants referred to in subsection 4.1(b) or the securities, rights, options, warrants, evidences of indebtedness or assets referred to in subsection 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 or effective date, as the case may be.

(h)

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

- 21 -

and shall apply to successive subdivisions, redivisions, 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, 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 subsection 4.1(h) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

(i)

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 Warrantholder is entitled to receive upon the exercise of his 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 or other property or securities a 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 Shares on Exercise of Warrant

All shares of any class or other securities or property which a 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 shares which such Warrantholder is entitled to acquire pursuant to such Warrant.

4.3

No Adjustment for Stock Options or Warrants

Anything in this Article 4 to the contrary notwithstanding, no adjustment shall be made in the acquisition rights attached to the Warrants if the issue of Common Shares is being made pursuant to this Indenture, pursuant to any stock option, stock purchase, stock appreciation rights or other employee compensation plan in force from time to time for directors, officers, employees or consultants of the Corporation or any of its Subsidiaries, as the case may be, or pursuant to any warrant outstanding immediately prior to the Effective Date.

4.4

Determination by Corporation’s Auditors

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 the Corporation’s Auditors or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by the Corporation. Such Auditors or accountants shall have access to all necessary records of the Corporation, and such determination shall be binding upon the Corporation, the Trustee, all Warrantholders and all other persons interested therein (absent manifest error).

- 22 -

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 number of Common Shares which are to be received upon the exercise thereof, 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 the Common Shares or other securities or property 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 Article 4, deliver a certificate of the Corporation to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment shall be supported by a certificate of the Corporation’s Auditors verifying such calculation. When so verified, the Trustee shall forthwith give notice, supplied by the Corporation and at the Corporation’s expense, to the Warrantholders specifying the event requiring such adjustment or readjustment and the results thereof including the resulting Exercise Price; provided that, if the Corporation has given notice under Section 4.7 covering all the relevant facts in respect of such event, no such notice need be given under this Section 4.6.

4.7

Notice of Special Matters

The Corporation covenants with the Trustee that, so long as any Warrant remains outstanding, it will give notice to the Trustee and to the Warrantholders of its intention to fix the record date for any event referred to in subsections 4.1(a), (b), (c) or (d) or the proposed effective date for a Corporate Transaction which may give rise to an adjustment of the Exercise Price. 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 10 Business Days prior to such applicable record date.

4.8

No Action after Notice

The Corporation covenants with the Trustee that it will not close its transfer books or take any other corporate action which might deprive the holder of a Warrant of the opportunity to exercise its right of acquisition pursuant thereto during the period of 10 Business Days after the giving of the certificate or notices set forth in Sections 4.6 and 4.7 or, in the case of a Corporation Transaction.

- 23 -

4.9

Protection of Trustee

Except as provided in Section 9.2, the Trustee:

(a)

shall be entitled to act and rely on any adjustment calculation of the directors or the Corporation’s Auditors;

(b)

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, 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;

(c)

shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Shares or of any shares or other securities or property which may at any time be issued or delivered upon the exercise of the rights attaching to any Warrant;

(d)

shall not 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

(e)

shall not incur any liability or responsibility whatsoever 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.

4.10

Other Adjustments

In case the Corporation after the date hereof shall take any action affecting the Common Shares, other than an action described in Article 4 which in the opinion of the directors would have a material adverse affect on the rights of Warrantholders, the Exercise Price and/or the number and/or kind of Common Shares purchasable upon exercise, there shall be an adjustment in such manner, if any, and at such time, by action by the directors subject to the prior consent of the Toronto Stock Exchange, if applicable. Failure of the taking of action by the directors so as to provide for an adjustment prior to the effective date of any action by the Corporation affecting the Common Shares shall be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

ARTICLE 5

Rights and Covenants of The Corporation

5.1

Optional Purchases by the Corporation

The Corporation may from time to time purchase by private contract, in the open market, on any stock exchange or otherwise any of the Warrants.

- 24 -

other terms as the Corporation, in its sole discretion, may determine subject to compliance with all applicable laws.

The Warrant Trustee is hereby irrevocably appointed (and the successive respective Warrantholders by taking and holding the same shall be conclusively deemed to have so appointed the Warrant Trustee) the true and lawful attorney-in-fact of the respective Warrantholders or on behalf of the Warrantholders as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the Warrantholders themselves if and to the extent permitted hereunder, for any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and documents and to do and perform any and all such acts and things for and on behalf of the Warrantholders, as may be necessary or advisable in the opinion of the Warrant Trustee, in order to have the respective claims of the Warrant Trustee and of the Warrantholders against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that nothing contained in this Indenture shall be deemed to give the Warrant Trustee, unless so authorized by extraordinary resolution (as provided in Section 7.11), any right to accept or consent to any plan of reorganization or otherwise by action of any character in such proceeding to waive or change in any way any right of any Warrantholder.

The undersigned (A) acknowledges that the sale of the common shares/warrants (circle one) represented by certificate number of TransAtlantic Petroleum Corp. to which this declaration relates is being made in reliance on Rule 904 of Regulation S under the United States Securities Act of 1933, as amended (the “1933 Act”) and (B) certifies that (1) the undersigned is not an affiliate (as defined in Rule 405 under the 1933 Act), (2) the offer of such securities was not made to a person in the United States and either (a) at the time the buy order was originated, the buyer was outside the United States, or the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States, or (b) the transaction was executed on or through the facilities of the Toronto Stock Exchange and neither the seller nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States, (3) neither the seller nor any person acting on its behalf engaged in any directed selling efforts in connection with the offer and sale of such securities, (4) the sale is bona fide and not for the purpose of “washing off” the resale restrictions imposed because the securities are “restricted securities” (as such term is defined in Rule 144(a)(3) under the 1933 Act), (5) the seller does not intend to replace such securities with fungible unrestricted securities; (6) the contemplated sale is not a transaction, or part of a series of transactions which, although in technical compliance with Regulation S, is part of a plan or scheme to evade the registration provisions of the 1933 Act. Terms used herein have the meanings given to them by Regulation S under the 1933 Act; and (7) in the case of an affiliate of the Corporation, no selling concession, fee or other remuneration is paid in connection with such offer or sale other than the usual and customary broker’s commission that would be received by a person executing such transaction as agent.
