CONVERSION

(a)

Conversion

(i)

At any time from the Effective Date until the Holder demands repayment or the Maturity Date, the Holder shall have the option, but is not obligated to, deliver to the Issuer, a Notice of Conversion, setting forth the principal amount of the Outstanding Indebtedness to be converted, such Notice of Conversion to be substantially in the form set forth in Schedule B hereto, duly executed by the Holder or its successors or assigns or its or their attorney duly appointed by an instrument in writing in form and executed in a manner reasonably satisfactory to the Issuer, confirming the registration and delivery instructions for the Common Shares or Preferred Shares to be issued upon such conversion. Thereupon the Holder, its successors or assigns, or such Person as it or they may direct, shall be entitled to be entered in the books of the Issuer as at the Date of Conversion as the holder of the number of Common Shares or Preferred Shares, as applicable, into which the portion of the principal amount of Outstanding Indebtedness is converted at the Conversion Price in accordance with the provisions of this Section 3 and, the Issuer shall deliver to the Holder or its successors or assigns, or such Person as it or they may direct, a certificate or certificates for such Common Shares or Preferred Shares, as applicable.

(ii)

For the purposes of this Section 3, the conversion of the principal amount of the Outstanding Indebtedness converted hereunder shall be deemed to have occurred on the date upon which the Notice of Conversion is delivered to the Issuer (the "Date of Conversion"), and the Person or Persons entitled to receive Common Shares or Preferred Shares shall become the holder or holders of record of such Common Shares or Preferred Shares, as applicable, on such Date of Conversion.

13

(iii)

From and after the Date of Conversion, the portion of this Debenture subject to the Notice of Conversion (the "Converted Principal Amount") shall not be considered as outstanding, interest shall cease to accrue after such date on the Converted Principal Amount and the Holder shall have no right under this Debenture except to receive the certificate representing the Common Shares for the Converted Principal Amount. The Issuer shall issue a new Debenture certificate, dated the date of Conversion, reflecting the decreased principal amount of the Debenture after giving effect to the Converted Principal Amount.

(iv)

The Holder shall, in respect of any Outstanding Indebtedness which is converted to Common Shares or Preferred Shares in accordance with this Section 3, be entitled to receive accrued and unpaid interest in respect thereof up to the Date of Conversion, and the holder of the Common Shares or Preferred Shares, as applicable, issued upon such conversion shall be entitled to receive any dividends declared in favour of Shareholders of record on and after the Date of Conversion, from which applicable date such Common Shares or Preferred Shares will for all purposes be and be deemed to be issued and outstanding as fully paid and non-assessable Common Shares or Preferred Shares, as applicable.

(v)

The Holder may convert the interest amount of any Outstanding Indebtedness in the same manner as set out above, mutatis mutandis, relating to the principal amount of any Outstanding Indebtedness, provided that the Issuer first obtains any necessary approval of the TSX and the Issuer and the Holder satisfy any requirements of the TSX with respect thereto, including TSX requirements relating to the conversion price applied to the Outstanding Indebtedness. If requested by the Holder, the Issuer shall use reasonable commercial efforts to accommodate the Holder's wish to convert the interest amount of any Outstanding Indebtedness into Common Shares and to seek and obtain any necessary approvals to effect same.

(vi)

Unless an individual who holds the ultimate investment making authority on behalf of the Holder has: (a) completed a Personal Information Form (a "PIF"), (b) submitted such PIF to the TSX, and (c) had such PIF cleared by the TSX, at no time shall the Holder be permitted to convert any portion of the principal amount of any Outstanding Indebtedness or interest accrued thereon if, after the conversion of such amounts, the Holder shall own (taking into account any Common Shares acquired other than as a result of this Debenture) more than 9.9% of the outstanding Common Shares of the Issuer.

(b)

Adjustment of Conversion Price

(i)

Adjustment for Stock Dividends, Subdivisions, Combinations or Consolidations

If and whenever at any time after the date hereof the Issuer shall:

(1)

issue Common Shares to all or substantially all of the holders of outstanding Common Shares as a stock dividend or make a distribution on its outstanding Common Shares payable in Common Shares;

14

(2)

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

(3)

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

(each of the events enumerated in the clauses (1), (2) and (3), above, being hereinafter referred to as a "Common Share Reorganization"), the Conversion Price shall be adjusted effective immediately after the record date or effective date, as the case may be, which is used to determine the holders of outstanding Common Shares for the happening of a Common Share Reorganization, by multiplying the Conversion Price in effect immediately prior to such record date or effective date by a fraction, the numerator of which shall be the number of Common Shares outstanding on such record date or effective date before giving effect to such Common Share Reorganization, and the denominator of which shall be the number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization.

(ii)

Adjustment for Reclassification, Exchange and Substitution

If and whenever at any time after the date hereof there shall be a reclassification of the Common Shares at any time outstanding or a change of the outstanding Common Shares into other securities, (other than a Common Share Reorganization), or a consolidation, arrangement, amalgamation or merger of the Issuer with or into any other Person (other than a consolidation, arrangement, amalgamation 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 transfer of all or substantially all of the assets of the Issuer to another Person (any of such events being herein called a "CapitalReorganization"),the holder, upon any exercise of its conversion rights hereunder to acquire Common Shares after the effective date of such Capital Reorganization, shall be entitled to receive, and shall accept, upon such conversion, in lieu of the number of Common Shares to which the holder was theretofore entitled upon such conversion, the aggregate number of shares, other securities or other property which the Holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, the Holder had been the registered holder of the number of Common Shares that the Holder was theretofore entitled to acquire upon such conversion. If mutually determined appropriate by the Holder and the Issuer, each acting reasonably, appropriate adjustments shall be made following any such Capital Reorganization in the application of the provisions set forth herein, with respect to the rights and interest thereafter of the holder and the adjustments to the Conversion Price to the end that such provisions shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares, other securities or other property thereafter deliverable upon the conversion of this Debenture.

15

(iii)

Adjustments for Rights Offerings

If and whenever at any time after the date hereof, the Issuer shall issue, or fix a record date for the issuance of, Options to the holders of all or substantially all of the Common Shares entitling them (for a period expiring within 60 days after such record date) 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) (the "Rights Offering Price") less than the then applicable Current Market Price (each such event being herein referred to as a "Rights Offering"),the Conversion Price shall be adjusted effective as of such record date (or in the event that the Common Shares will commence trading on an ex-rights or similar basis prior to such record date, such adjustment shall be made effective as of such earlier time) to be equal to the Rights Offering Price.

For greater certainty, the foregoing adjustment shall be made in the event that any Options become exercisable under any shareholder rights plan adopted by the Issuer. To the extent that such Options are not so issued, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record had not been fixed.

(iv)

Adjustment for Special Distributions

If and whenever at any time after the date hereof, the Issuer shall issue or distribute, or fix a record date for the issuance or distribution (a "Special Distribution"), to holders of all or substantially all of the holders of the Common Shares, of:

(1)

shares of the Issuer of any class (other than Common Shares);

(2)

Options;

(3)

evidences of indebtedness; or

(4)

any other property or assets of the Issuer (including cash, other than cash dividends paid to Shareholders in the ordinary course of business);

and such issuance or distribution does not constitute a Common Share Reorganization, Capital Reorganization or Rights Offering, the Conversion Price shall be adjusted effective immediately as of such record date (or in the event that the Common Shares will commence trading on an ex-distribution or similar basis prior to such record date, such adjustment shall be made effective as of such earlier time) to a price determined by multiplying the Conversion Price then in effect by a fraction:

(1)

the numerator of which shall be:

a.

the product obtained when the number of Common Shares outstanding on such record date is multiplied by the Current Market Price of the Common Shares on such record date; less

b.

the fair market value, as mutually determined by the Holder and the Issuer, each acting reasonably, of the shares, Options, evidences of indebtedness, property or other assets distributed in the Special Distribution; and

16

(2)

the denominator of which shall be the product obtained when the number of Common Shares outstanding on such record date is multiplied by the Current Market Price of the Common Shares on such record date.

To the extent that such Special Distribution is not so made, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed.

(v)

No Impairment

The Issuer shall not, by amendment of its articles or through any reorganization, transfer of assets, consolidation, merger, amalgamation, arrangement, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance of any of the terms to be observed or performed hereunder by the Issuer, but will at all times in good faith assist in the carrying out of all the provisions of this Section 3(b) and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against impairment.

(vi)

Certificate as to Adjustments

Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 3(b), the Issuer at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to the Holder a certificate executed by the Chief Executive Officer or Chief Financial Officer of the Issuer setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Issuer shall, upon the written request at any time of the Holder, furnish or cause to be furnished to such Holder a similar certificate setting forth all such adjustments and readjustments, the Conversion Price in effect at such time, and the number of Common Shares or the amount, if any, of other securities (as determined under Section 3(b)(ii)), which at such time would be issuable upon the conversion of this Debenture.

(c)

Fractional Interests

The Issuer shall not be required to issue fractional Common Shares or fractional Preferred Shares upon the conversion of Outstanding Indebtedness pursuant to this Section 3. Any fractions will be rounded to the nearest whole number with fractions of one-half or greater being rounded to the next higher whole number and fractions of less than one-half being rounded to the next lower whole number.

4.

SECURITY

The Issuer acknowledges that the Security shall be continuing security for, among other things, the payment, observance and performance of the Secured Obligations.

The Security will be in the form of a general security agreement, in a form satisfactory to the Holder, acting reasonably, and will be registered in all such offices and in all such jurisdictions as the Holder may from time to time require or deem appropriate to protect or perfect the Liens created thereby.

17

(iii)

The Issuer will, in connection with the provision of any Security referred to in this Debenture, including any amended, new or replacement Security:

(1)

provide or cause to be provided to the Holder such security instruments and other documents which the Holder deems are necessary to give full force and effect to the provisions of this Section 4; and

(Items (1) through (2) immediately above are hereinafter referred to as the "Security Grant Obligations")

(iv)

The Holder may grant extensions, take and give up securities, accept compositions, grant releases and discharges and otherwise deal with the Issuer and with other third parties, guarantors, sureties or securities as the Holder may see fit without prejudice to the liability and obligations of the Issuer to the Holder under the Debenture Documents.

(v)

The Security will not operate so as to create any merger or discharge of any amount owing by the Issuer under the Debenture Documents, or of any assignment, transfer, guarantee, Lien, contract, promissory note, bill of exchange or security of any form held or which may hereafter be held by the Holder from the Issuer.

(vi)

No failure or delay on the part of the Holder to exercise any right, power or remedy given under the Debenture Documents, by statute, at law, in equity or otherwise will operate as a waiver thereof, nor will any single or partial exercise of any right preclude any other exercise thereof or the exercise of any right, power or remedy, nor will any waiver by the Holder be deemed to be a waiver of any subsequent similar or other event.

(b)

Acknowledgement of Subordination of Security

(i)

The Debenture will be a direct secured obligation, pursuant to a registered general security agreement, and rank ahead of unsecured debt holders and equity holders, but subordinate to the Senior Indebtedness. Subject to statutory preferred exceptions and the limited subordination to the Senior Indebtedness as provided herein, this Debenture will participate pro rata (based on invested capital) with any other debt secured under the Debenture Documents, but in priority to other secured obligations of the Corporation in any liquidation or distribution of assets, shares or other property as a result of any liquidation.

(d)

Registrations

The Issuer hereby authorizes the Holder to file or register such financing statements, financing change statements or other registrations and other documents in all such jurisdictions and offices as the Holder may deem appropriate to perfect on an ongoing basis and continue the Security and the Issuer, upon the occurrence of an Event of Default, hereby irrevocably constitutes and appoints the Holder (or its nominee) from time to time as its true and lawful attorney, with full power of substitution, to do any of the foregoing in the name of the Issuer whenever and wherever it may be deemed necessary or expedient.

(e)

Paramountcy

Should any of the provisions of the Security conflict with or be inconsistent with any of the provisions of this Debenture, the provisions of this Debenture shall prevail to the extent necessary to resolve any such conflict or inconsistency. For greater certainty, if there is any right or remedy of the Holder set forth in this Debenture which is not set forth in the Security, or if there is any right or remedy of the Holder set forth in the Security which is not set forth in this Debenture, the existence of such right or remedy shall not constitute a conflict.

GENERAL PROVISIONS

(a)

Interest Rate Provisions

(i)

The theory of deemed reinvestment shall not apply to the calculation of interest or payment of fees or other amounts hereunder and notwithstanding anything contained in this Debenture or in any other Debenture Document, all interest and fees payable by the Issuer to the Holder shall accrue from day to day and be computed as described herein in accordance with the "nominal rate" method of interest calculation.

(ii)

All interest payable under this Debenture or any document executed pursuant to this Debenture shall be payable both before and after default, demand, maturity and judgment. To the extent permitted by applicable law, the provisions of the Judgment Interest Act (Alberta) will not apply to this Debenture and are hereby expressly waived by the Issuer.

(iii)

Notwithstanding anything herein or in any other Debenture Document to the contrary, in the event that any provision of this Debenture or any Security would oblige the Issuer to make any payment of interest or other amount payable to the Holder hereunder in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by the Holder of interest at a criminal or prohibited rate (as such terms are construed under the Criminal Code (Canada) or any other applicable law), notwithstanding such provision, such amount or rate shall be deemed to have been adjusted nunc pro tunc to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by the Holder of interest at a criminal or prohibited rate, such adjustment to be effected, to the extent necessary, firstly, by reducing the amount or rate of interest exigible under this Debenture; and thereafter, by reducing any fees, commissions, premiums and other amounts which would constitute interest for the purposes of Section 347 of the Criminal Code (Canada), as may be amended from time to time, or any other applicable law. Any amount or rate of interest referred to in this Debenture shall be determined in accordance with generally accepted actuarial practices and principles over the term of the Debenture and, in the event of a dispute, a certificate of a fellow of the Canadian Institute of Actuaries appointed by the Holder shall be conclusive for the purposes of such determination.

(iv)

In determining whether or not the interest paid or payable under this Debenture exceeds the maximum amount permitted by the foregoing paragraph, the Issuer and the Holder shall, to the maximum extent permitted under the Criminal Code (Canada), or any other applicable law, characterize any non-principal payments as an expense, fee or premium or other payment rather than as interest, as may be necessary to reduce the amount otherwise characterized as interest pursuant to such applicable law, exclude voluntary prepayments and the effects thereof and amortize, prorate, allocate and spread the total amount of interest rateably over the longer of the contemplated term or the actual term of this Debenture.

(b)

Lost Debenture

If this Debenture is stolen, lost, mutilated or destroyed, the Issuer shall, on such reasonable terms as to indemnity or otherwise as it may impose, deliver a replacement Debenture of like denomination, tenor and date as this Debenture which is so stolen, lost, mutilated or destroyed.



24

(c)

No Impairment

To the extent permitted by Applicable Law, the Security shall not be impaired by any indulgence, moratorium or release which may be granted, including any renewal, extension or modification which may be granted with respect to any Secured Obligation or any part thereof or any interest therein, or any release or indulgence granted to any endorser, guarantor or surety of any of the Secured Obligations.

(d)

Inconsistency

To the extent that any provisions of this Debenture conflict with or are inconsistent with any of the provisions of the Subscription Agreement, this Debenture shall govern and prevail to resolve such conflict or inconsistency. For greater certainty, if there is any right or remedy of the Holder set forth in this Debenture which is not set forth in the Subscription Agreement, or if there is any right or remedy of the Holder set forth in the Subscription Agreement which is not set forth in this Debenture, the existence of such additional right or remedy shall not constitute a conflict or inconsistency.

(e)

No Set-Off

The obligation of the Issuer to make all payments hereunder will be absolute and unconditional and will not be affected by any circumstance, including:

(i)

any set off, compensation, counterclaim, recoupment, defence or other right which the Issuer may have against the Holder, or anyone else for any reason whatsoever; and

(ii)

any insolvency, bankruptcy, reorganization or similar proceedings by or against the Issuer.

(f)

(g)

Payments

All payments under or in respect of this Debenture, whether of principal, interest, commitment fees or otherwise, are to be paid by wire transfer by the Issuer to such account as the Holder may advise the Issuer from time to time. The Issuer will be entitled to withhold any and all amounts as required by applicable law and shall remit such withholdings to the applicable governmental authority. If the Issuer is required to make a deduction or withholding, the amount payable to the Holder must be grossed up to ensure that, after the deduction or withholding, the amount received by the Holder is the same as the amount that would have been paid if no deduction or withholding was required.

All such payments shall be made at or before 1:00 p.m. (Calgary time) on the day such payment is due or if such day is not a Business Day, the first Business Day immediately preceding such day.
