              2.1

            	
              Terms of Debenture

            


       

      

    

    This Debenture is subject to the following terms and conditions:

    
      

      

      	

            	(a)	
              The Debentures shall be dated as of the date on which the Debentures are issued by the Corporation pursuant to this Indenture (the “Issuance Date”) and shall bear interest from and including the date of issuance at the rate of 8.0% per annum, payable in quarterly installments in arrears on August 31, November 30, February 28 and May 31 in each year, the first such interest payment to fall due on August 31, 2022, and the last such interest payment
                to fall due on April ___, 2026, payable after as well as before maturity and after as well as before default, demand and judgment, with interest on amounts in default at the same rate, compounded semi-annually and calculated based on a
                360-day year consisting of twelve 30-day months.

            


       

      	

            	(b)	
              Maturity. This Debenture shall mature on April [●], 2026 (the “Maturity Date”).

            


       

      	

            	(c)	
              Payment of Interest. Subject to receipt of applicable regulatory approval
                (including the approval of such stock exchange(s) on which the Shares are listed, if applicable) and compliance with the Shareholder Rights Plan, if any, the Corporation shall satisfy its Interest Obligation on this Debenture on each
                Interest Payment Date (including, for greater certainty, following conversion or redemption or on the Maturity Date) by delivering: (i) cash for that portion of the interest equal to 6% per annum; and (ii) Shares for the balance of the
                interest equal to 2% per annum, subject to any required regulatory approval and provided that such payment in Shares does not cause the interest expense to be a nondeductible expense for tax purposes by the Corporation. The Shares to be
                issued in satisfaction of the Corporation’s Interest Obligation on this Debenture shall be issued at the Current Market Price. If the Current Market Price is lower than the price required by the policies or rules of any applicable stock
                exchange or market, the Shares to be issued in satisfaction of the Corporation’s Interest Obligation on this Debenture shall be issued at the lowest price permitted by such stock exchange or market. If on the applicable Interest Payment

                the issuance of Shares in satisfaction of part of the Corporation’s Interest Obligation would trigger the operation of the Shareholder Rights Plan, if any, or a vote of the Corporation's shareholders, then the Corporation shall satisfy its
                entire Interest Obligation in respect of such Interest Payment Date in cash. If part of the Corporation’s Interest Obligation payable on an Interest Payment Date is to be satisfied in Shares, the Corporation shall confirm by the end of the
                business day before the Interest Payment Date by Officer’s Certificate compliance with the above noted conditions for issuance of the Shares, and confirm the Current Market Price and the number of Shares to be issued in connection with the
                Interest Payment Date. If part of the Corporation’s Interest Obligation payable on an Interest Payment Date is to be satisfied in Shares, the Corporation shall issue or cause to be issued the Shares as at the Interest Payment Date, and
                deliver or cause to be delivered such Shares to the Debentureholder accordingly.

                principal amount thereof, plus, accrued and unpaid interest, if any, on this Debenture up to, but excluding, the Secured Financing Put Date (collectively, the “Total Secured Financing Put Price”), payable from the proceeds of the Secured Financing Package.

            


       

      	

            	(ii)

            	(iv)	
              To the extent that the Debentureholder has exercised the Secured Financing Put Right in respect of this Debenture, this Debenture shall become due and payable at the
                Total Secured Financing Put Price on the Secured Financing Put Date, in the same manner and with the same effect as if it were the date of maturity specified in this Debenture, anything therein or herein to the contrary notwithstanding, and

            	(m)	
              Conditional Early Conversion Upon Announcement of Change of Control. From
                and after the announcement by the Corporation of a Change of Control that is recommended by the directors, subject to the provisions and conditions of this Section 2.1(m), the Corporation shall have a right (the “Early Conversion Right”) to require the Debentureholder to convert some or the whole or any part which is $1,000 or an multiple thereof, of the principal
                amount of this Debenture into Shares at the Conversion Price. The terms and conditions of such right are set forth below:

            


       

      
        
          


        15

      

      	

            	(i)	
              The Early Conversion Right may only be exercised by the Corporation provided
                  that: (i) the directors have recommended that the shareholders of the Corporation approve such Change of Control and such recommendation is included in the announcement of the Change of Control; (ii) the amount that the holders of
                Debentures will receive upon completion of the Change of Control per Share received on conversion of this Debenture exceeds the Conversion Price; and (iii) either (A) such amount is payable in cash, or (B) such amount is payable, in whole
                or in part, in property or securities which the holder of this Debenture, in its sole discretion, wishes to receive.

            


       

      	

            	(ii)

            	(iii)	
              The Debentureholder may elect, in its sole discretion, to not have this Debenture converted pursuant to the Early Conversion Right if the consideration to be received

                recommended by the directors and for which the directors have determined to exercise the Early Conversion Right, give written notice to the Debentureholder of the pending Change of Control (the “Early Conversion Notice”). The Early Conversion Notice shall be prepared by the Corporation and shall include (A) a description of the pending Change of Control, including the
                price to be paid for each Share in the Change of Control and the form of consideration such price will take; (B) a statement of the Corporation’s intention to exercise the Early Conversion Right, including confirmation of compliance with

                statement that the conversion pursuant to the Early Conversion Right is conditional upon the completion of the Change of Control and if such Change of Control is not completed, this Debenture will remain outstanding.

            	(v)	
              To the extent applicable, paragraphs 5.2, 5.3, 5.5. and 5.7 of this Debenture shall apply mutatis mutandis to the exercise by the Corporation of the Early Conversion

                Mutilation, Loss, Theft or Destruction

              


         

        

      

    

    In case this Debenture shall become mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue and deliver, a new Debenture
      upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in the form of this Debenture and be ranked
      equally in accordance with its terms with all other Debentures originally issued on the Issuance Date. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Corporation such evidence of the loss, theft
      or destruction of this Debenture as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion along with any other documents that might be required by the

              	(a)	
                This Debenture shall bear interest (i) from and including the Issuance Date, or (ii) from and including the last Interest Payment Date to which interest shall have
                  been paid or on the outstanding principal amount of this Debenture, whichever shall be the later, to but excluding the next Interest Payment Date.

              


         

        	

              	(b)	
                Interest for any period of less than six months shall be computed on the basis of a year of 360 days consisting of twelve 30-day months (the “deemed year”). Whenever interest is computed on the basis of the deemed year, interest shall be expressed as a yearly rate by multiplying
                  such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

              


         

      

    

    
      	
              2.4

            	
              Payment of Interest

            


       

      

    

    The following provisions shall apply to this Debenture, except as otherwise provided in Section 2.1(a) or elsewhere in this Debenture or specified in a
      Board Resolution or an Officer’s Certificate relating to this Debenture:

    
      
        


      17

    

    

    

    
      	
              (a)

            	
              As interest becomes due on this Debenture (except on conversion, at maturity or on redemption, when interest may at the option of the Corporation
                be paid upon surrender of this Debenture) the Corporation (which shall be confirmed by the Corporation by Officer’s Certificate pursuant to Section 2.1(c)) shall send or forward a check by prepaid ordinary mail, wire, electronic transfer of
                funds or such other means as may be agreed to by the Debentureholder and, if applicable, deliver the Shares, pursuant to Section 2.1(c), in payment of such interest to the order of the registered holder of such Debenture appearing on the
                registers maintained by the Corporation as at the close of business on the fifth Business Day prior to the applicable Interest Payment Date and addressed to the holder at the holder’s last address appearing on the register (or in the case
                of joint holders, to such address of one of the joint holders), unless such holder otherwise directs in writing to the Corporation in advance. If cash payment is made by check, such check shall be forwarded at least three days prior to the
                Interest Payment Date and if payment is made by other means (such as wire or electronic transfer of funds), such payment shall be made in a manner whereby the holder receives credit for such payment on the Interest Payment Date. The mailing
                of such check or the making of such payment by other means shall, to the extent of the sum represented thereby, satisfy and discharge all liability for interest on this Debenture, unless in the case of payment by check, such check is not
                paid at par on presentation. In the event of non-receipt of any check for or other payment of interest by the person to whom it is so sent as aforesaid, the Corporation will issue to such person a replacement check or other payment for a
                like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its
                control (including, without limitation, any interruption in mail service) from making payment of any interest due on this Debenture in the manner provided above, the Corporation may make payment of such interest in any other manner
                acceptable to the Debentureholder with the same effect as though payment had been made in the manner provided above.

              (a)

            	
              The Corporation will be entitled to deduct and withhold any applicable Taxes or similar charges (including interest, penalties or similar amounts
                in respect thereof) imposed or levied by or on behalf of any government or of any state, province or territory thereof, or any authority or agency therein or thereof, having power to tax, from any payment to be made on or in connection with
                this Debenture (including, for greater certainty, the issuance of Shares upon any conversion of Debentures and in respect of an Interest Obligation), provided that the Corporation forthwith remits such withheld amount to such government,
                authority or agency and files all required forms in respect thereof and, at the same time, provides copies of such remittance and filing to the Debentureholder, the amount of any such deduction or withholding will be considered an amount
                paid in satisfaction of the Corporation’s obligations under this Debenture.

              (b)

            	
              The Corporation will pay any stamp, issue, registration, documentary or other similar Taxes and other duties (including interest and penalties)
                payable in respect of the creation, issue, offering, execution or enforcement of this Debenture, or any documentation with respect thereto.

                  this Debenture be and be deemed to be the owner thereof, and the Corporation will not be affected by any notice or knowledge to the contrary except as required by statute or by order of a court of competent jurisdiction, and payment of or

        REDEMPTION AND PURCHASE OF DEBENTURES

     

    
      	
              4.1

            	
              Applicability

            


       

      

    

    In the circumstances described in, and subject to the additional procedures set out in, Section 2.1(i), and subject to compliance with applicable laws, the
      Corporation shall have the right to redeem this Debenture either in whole at any time or in part from time to time before maturity. In addition to the procedures set out in the sections referred to above, the following procedures will apply.

              Partial Redemption

            


       

      

    

    If less than the whole principal amount of this Debenture is at any time to be redeemed, the Corporation shall, at least 15 days before the date upon which
      the Redemption Notice is to be given, notify the Debentureholder by a Written Direction of the Corporation of its intention to redeem such portion of the aggregate principal amount of this Debenture to be redeemed. This Debenture may be redeemed in
      the minimum principal amount of $1,000 or a multiple thereof. If this Debenture becomes subject to redemption in part only, upon surrender of this Debenture for payment of the Redemption Price, together with interest accrued but unpaid to but
      excluding the Redemption Date, the Corporation shall execute and deliver without charge to the holder thereof or upon the holder’s order one or more new Debentures for the unredeemed part of the principal amount of this Debenture so surrendered.
      Unless the context otherwise requires, the terms “Debenture” or “Debentures” as used in this Article 4 shall be deemed to mean or include any part of the principal amount of this Debenture which in accordance with the foregoing provisions has become
      subject to redemption.

    Written notice of redemption (the “Redemption Notice”)
      of this Debenture shall be given to the holders of this Debenture at least 30 days and not more than 60 days prior to the date fixed for redemption (the “Redemption
        Date”) in the manner provided in Section 13.2. Every such notice shall specify the aggregate principal amount of Debenture called for redemption, the Redemption Date, the Redemption Price, any right of the holder to convert such Debenture
      and the places of payment and shall state that interest upon the principal amount of this Debenture called for redemption shall cease to accrue and be payable from and after the Redemption Date.

              Debenture Due on Redemption Date

            


       

      

    

    Upon notice having been given as aforesaid, this Debenture shall thereupon be and become due and payable at the Redemption Price, together with accrued but
      unpaid interest to but excluding the Redemption Date, on the Redemption Date specified in such notice, in the same manner and with the same effect as if it were the date of maturity specified in this Debenture, anything therein or herein to the
      contrary notwithstanding, and from and after such Redemption Date, if the monies necessary to redeem this Debenture shall have been paid as provided in Section 4.5, interest upon this Debenture shall cease.

              Payment of Redemption Monies

            


       

      

    

    Redemption of this Debenture shall be provided for by the Corporation paying the Debentureholder, on or before 11:00 a.m. (Houston time) on the Redemption
      Date specified in the applicable Redemption Notice, such sums of money as may be sufficient to pay the Redemption Price of this Debenture, plus accrued but unpaid interest thereon up to but excluding the Redemption Date. The Corporation shall also
      deliver or cause to be delivered the Shares pursuant to Section 2.1(c). Every such payment shall be irrevocable. Upon receipt of such payment, the Debentureholder shall surrender this Debenture to the Corporation.

              Failure to Surrender Debenture Called for Redemption

            


       

      

    

    In case the holder of this Debenture shall fail to surrender this Debenture, provided that the entirety of the Redemption Price plus accrued interest and
      unpaid interest has been paid to the Debentureholder, to that extent, this Debenture shall thereafter not be considered as outstanding hereunder.

              Cancellation of Debentures Redeemed

            


       

      

    

    Subject to the provisions of Sections 4.2 and 4.8 as to the redemption or purchase of this Debenture in part, to the extent redeemed, the portion of the
      aggregate principal amount of this Debenture which has been satisfied under this Article 4 shall forthwith be cancelled and no Debenture shall be issued in substitution therefor. The Corporation shall, if applicable, without charge forthwith deliver
      to the holder a new Debenture in an aggregate principal amount equal to the principal amount of this Debenture so surrendered which has not been redeemed or purchased.

              (a)

            	
              The Corporation may, at any time and from time to time, purchase this Debenture in the market (which shall include purchase from or through an
                investment dealer or a firm holding membership on a recognized stock exchange) or by tender offer or by private contract, at any price, subject to compliance with Applicable Securities Laws regarding issuer tender offers. If an Event of
                Default has occurred and is continuing, the Corporation may purchase all or any of this Debenture as aforesaid. All Debentures so purchased shall be cancelled and no Debentures shall be issued in substitution therefor.

            


       

      

    

    
      	
              (b)

            	
              If, upon a partial tender offer, more Debentures are tendered at the same lowest price that the Corporation is prepared to accept, the Debentures
                to be purchased by the Corporation shall be selected by the Corporation, in such manner (which may include selection by lot, selection on a pro
                  rata basis, random selection by computer or any other method) or in such other manner consented to by the exchange or market on which the Debentures are then listed and the Corporation considers appropriate, from the Debentures
                tendered by each tendering Debentureholder who tendered at such lowest price. The Debentureholder of which a part only is purchased, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such holder,
                one or more new Debentures for the unpurchased part so surrendered, and the Corporation shall deliver such new Debenture or Debentures upon receipt of the Debenture so surrendered.

                Subject to applicable regulatory approval (including the approval of such stock exchange(s) on which the Shares are listed, if applicable), this Debenture (subject,
                  however, to any applicable restriction on the conversion of this Debenture contained in Sections 2.1(e), 2.1(m) and/or 5.3(a)) will be convertible into Shares, at such conversion rate or rates, and on such date or dates and in accordance
                  with such other provisions as shall have been determined at the time of issue of this Debenture and shall have been expressed in this Debenture or in an Officer’s Certificate.

              


         

        	

              	(b)	
                Such right of conversion shall extend only to the maximum number of whole Shares into which the aggregate principal amount of this Debenture surrendered for
                  conversion at any one time by the holder thereof may be converted. Fractional interests in Shares shall be dealt with in the manner provided in Section 5.5.

              Revival of Right to Convert

            


       

      

    

    If this Debenture is called for redemption by the Corporation, but is not redeemed or the payment of the purchase price of this Debenture which has been
      tendered in acceptance of an offer by the Corporation to purchase this Debenture for cancellation is not made, in the case of a redemption upon due surrender of this Debenture or in the case of a purchase on the date on which such purchase is
      required to be made, as the case may be, then the right to convert this Debenture shall revive and continue as if this Debenture had not been called for redemption or tendered in acceptance of the Corporation’s offer, respectively.

    

    

    
      	
              5.3

            	
              Manner of Exercise of Right to Convert

            


       

      

      
        	

              	(a)	
                The holder of this Debenture desiring to convert this Debenture in whole or in part into Shares shall surrender this Debenture to the Corporation at its principal
                  office in Houston, Texas, together with the conversion notice in the form attached as Schedule “B” to this Debenture or any other written notice in a form satisfactory to the Corporation, in either case duly executed by the holder or its
                  executors or administrators or other legal representatives or its or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Corporation, exercising its right to convert this
                  Debenture in accordance with the provisions of this Article 5. If the number of Shares issuable upon a conversion of this Debenture would result in the Maximum Conversion Shares being exceeded such that the approval of one or more stock
                  exchange(s) on which the Shares are then listed is required for the Shares issuable upon a conversion this Debenture to be listed on such stock exchange(s), the Corporation shall use its reasonable commercial efforts to obtain the
                  approval of such stock exchange(s) (provided, for greater certainty, such commercially reasonable efforts shall not require the Corporation to seek securityholder approval, if required by such stock exchange(s)) and the conversion shall
                  be conditional on such approval(s) being obtained. Thereupon such Debentureholder or, subject to payment of all applicable stamp or security transfer taxes or other governmental charges and compliance with all reasonable requirements of
                  the Corporation, its nominee(s) or assignee(s), shall be entitled to be entered in the books of the Corporation as at the Date of Conversion (or such later date as is specified Section 5.3(b) or, if stock exchange approval is required in
                  respect of a conversion, as soon as practicable following the date such approval is obtained) as the holder of the number of Shares into which this Debenture is convertible in accordance with the provisions of this Article 5 and, as soon
                  as practicable thereafter, the Corporation shall deliver to such Debentureholder or, subject as aforesaid, its nominee(s) or assignee(s), a certificate or other evidence of such Shares.

              	(b)	
                For the purposes of this Article, this Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered in accordance with the provisions of this Article 5 and, in if this Debenture is surrendered by post or other
                  means of transmission, on the date on which it is received by Corporation at its principal office in Houston, Texas; provided that if this Debenture is surrendered for conversion on a day on which the register of Shares is closed, the
                  person or persons entitled to receive Shares shall become the holder or holders of record of such Shares as at the date on which such registers are next reopened.

              


         

        	

              	(c)	
                Any part, being $1,000 or an integral multiple thereof, of this Debenture in a denomination in excess of $1,000 may be converted as provided in this Article and all
                  references in this Debenture to conversion of this Debenture shall be deemed to include conversion of such parts.

              


         

        	

              	(d)	
                The holder of this Debenture of which only a part is converted shall, upon the exercise of its right of conversion surrender this Debenture to the Corporation, and
                  the Corporation shall cancel the same and shall, if applicable, without charge forthwith deliver to the holder a new Debenture in an aggregate principal amount equal to the unconverted part of the principal amount of this Debenture so
                  surrendered.

              


         

        	

              	(e)	
                The holder of this Debenture surrendered for conversion in accordance with this Section 5.3 shall be entitled to receive accrued and unpaid interest in accordance
                  with Section 2.1(c) in respect thereof up to but excluding the Date of Conversion of this Debenture and the Shares issued upon such conversion shall rank only in respect of distributions or dividends declared in favour of shareholders of
                  record on and after the Date of Conversion or such later date as such holder shall become the holder of record of such Shares pursuant to Section 5.3, from which applicable date they will for all purposes be and be deemed to be issued and
                  outstanding as fully paid, non-assessable Shares.

                Adjustment of Conversion Price

              


         

        

      

    

    The Conversion Price in effect at any date shall be subject to adjustment from time to time as set forth below.

     

    

    
      	

            	(a)	
              If and whenever at any time prior to the Time of Expiry the Corporation shall (i) subdivide or redivide the outstanding Shares into a greater number of Shares, (ii)
                reduce, combine or consolidate the outstanding Shares into a smaller number of Shares, or (iii) issue Shares or securities convertible into or exchangeable for Shares to the holders of all or substantially all of the outstanding Shares by
                way of a dividend or distribution (other than pursuant to any dividend re-investment or Share purchase plans or similar arrangements), the Conversion Price in effect on the effective date of such subdivision, redivision, reduction,
                combination or consolidation or on the record date for such issue of Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to
                the number of outstanding Shares resulting from such subdivision, redivision, dividend or distribution (including, in the case where securities convertible into or exchangeable for Shares are distributed, the number of Shares that would
                have been outstanding had all such securities been exchanged for or converted into Shares on such effective date or record date), or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number
                of outstanding Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this 5.4(a) shall occur. Any such issue of Shares by way of a dividend or
                distribution shall be deemed to have been made on the record date for the dividend or distribution for the purpose of calculating the number of outstanding Shares under Subsections 5.4(b) and 5.4(c) of this Section 5.4.

            


       

      	

            	(b)	
              If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the issuance of options, rights or warrants, but not including
                issuances of options, rights or warrants to employees of the Corporation pursuant to an equity incentive plan of the Corporation, to all or substantially all the holders of its outstanding Shares entitling them, for a period expiring not
                more than 45 days after such record date, to subscribe for or purchase Shares (or securities convertible or exchangeable into 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 Share on such record date, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion Price in effect on such record date by a
                fraction, of which the numerator shall be the total number of Shares outstanding on such record date plus that number of Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Shares offered
                for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price per Share, and of which the denominator shall be the total number of Shares
                outstanding on such record date plus the total number of additional Shares offered for subscription or purchase (or into which the convertible or exchangeable securities so offered are convertible). Such adjustment shall be made
                successively whenever such a record date is fixed. To the extent that any such options, rights or warrants are not so issued or any such options, rights or warrants are not exercised prior to the expiration thereof, the Conversion Price
                shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon the number of Shares (or securities convertible or
                exchangeable into Shares) actually issued upon the exercise of such options, rights or warrants, as the case may be.

            


       

      
        
          


        26

      

      	

            	(c)	
              If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the making of a distribution to all or substantially all the
                holders of its outstanding Shares of (i) shares of any class other than Shares (other than pursuant to any dividend re-investment or share purchase plans or similar arrangements), (ii) rights, options or warrants (excluding rights, options
                or warrants entitling the holders thereof for a period of not more than 45 days to subscribe for or purchase Shares or securities convertible or exchangeable into Shares), (iii) evidences of its indebtedness, or (iv) other assets (excluding
                dividends or distributions paid in the ordinary course) then, in each such case, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion Price in
                effect on such record date by a fraction, of which the numerator shall be the total number of Shares outstanding on such record date multiplied by the Current Market Price per Share on such record date, less the fair market value (as
                determined by an investment dealer chosen by the Corporation and subject to applicable exchange or market approval, which determination shall be conclusive) of such shares or rights, options or warrants or evidences of indebtedness or
                assets so distributed, and of which the denominator shall be the total number of Shares outstanding on such record date multiplied by such Current Market Price per Share. Such adjustment shall be made successively whenever such a record
                date is fixed. To the extent that such distribution is not so made, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which
                would then be in effect based upon such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be.

            


       

      	

            	(d)	
              Subject to Section 9.1, if and whenever at any time prior to the Time of Expiry, there is a reclassification of the Shares or a capital reorganization of the
                Corporation other than as described in Section 5.4(a) or a merger or consolidation, of the Corporation with or into any other person, or a sale or conveyance of all or substantially all the assets of the Corporation to any other person, or
                a liquidation, dissolution or winding up of the Corporation, any holder of a Debenture who has not exercised its right of conversion prior to the effective date of such reclassification, capital reorganization, merger, consolidation, sale
                or conveyance, or liquidation, dissolution or winding-up, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Shares then sought to be acquired by it, the number of shares or
                other securities or property of the Corporation or of the person resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such holder of a Debenture would have been
                entitled to receive on such reclassification, capital reorganization, merger, consolidation, sale or conveyance, or liquidation, dissolution or winding-up, if, on the record date or the effective date thereof, as the case may be, the holder
                had been the registered holder of the number of Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the conversion right.

            


       

      
        
          


        27

      

      	

            	(e)	
              In any case in which this Section 5.4 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the
                Corporation shall defer, until the occurrence of such event, issuing to the holder of any Debenture converted after such record date and before the occurrence of such event the additional Shares issuable upon such conversion by reason of
                the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional Shares
                upon the occurrence of the event requiring such adjustment and the right to receive any dividends or distributions made on such additional Shares declared in favour of holders of record of Shares on and after the Date of Conversion or such
                later date as such holder would, but for the provisions of this Section 5.4(e), have become the holder of record of such additional Shares pursuant to Section 5.4(b).

            


       

      	

            	(f)	
              The adjustments provided for in this Section 5.4 are cumulative 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, provided that, notwithstanding any other provision of this Section, no adjustment of the Conversion Price shall be required unless such
                adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect; provided however, that any adjustments which by reason of this Section 5.4(f) are not required to be made shall be carried forward and
                taken into account in any subsequent adjustment

            


       

      	

            	(g)	
              For the purpose of calculating the number of Shares outstanding, Shares owned by or for the benefit of the Corporation or any Subsidiary of the Corporation shall not
                be counted.

            


       

      	

            	(h)	
              If any question or dispute arises with respect to the adjustments provided in this Section 5.4, such question or dispute shall be conclusively determined by a firm of
                chartered accountants appointed by the Corporation (who may be the Auditors of the Corporation); such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation,
                and the Debentureholder (subject to manifest error).

            


       

      
        
          


        28

      

      	

            	(i)	
              In case the Corporation shall take any action affecting the Shares other than action described in this Section 5.4, which in the opinion of the directors would
                materially adversely affect the rights of Debentureholders, the Conversion Price shall be adjusted in such manner and at such time as the directors in their sole discretion may determine to be equitable in the circumstances. Failure of the
                directors to make such an adjustment shall be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

            


       

      	

            	(j)	
              Subject to the prior written consent of any stock exchange or market upon which the Shares are then listed, as the case may be, and if required, no adjustment in the
                Conversion Price shall be made in respect of any event described in Section 5.4(a), Section 5.4(b) or Section 5.4(c) if the holders of the Debentures are entitled to participate in such event on the same terms mutatis mutandis as if they had converted their Debentures prior to the effective date or record date, as the case may be, of such event.

            


       

      	

            	(k)	
              Except as stated above in this Section 5.4, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Shares at less than
                the Current Market Price for such Shares on the date of issuance.

            


      

      	
              5.5

            	
              No Requirement to Issue Fractional Shares

            


       

      

    

    The Corporation shall not be required to issue fractional Shares upon the conversion of this Debenture pursuant to this Article 5. If more than one
      Debenture shall be surrendered for conversion at one time by the same holder, the number of whole Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted. If any
      fractional interest in a Share would, except for the provisions of this Section 5.5, be deliverable upon the conversion of any principal amount of Debentures, the Corporation shall, in lieu of delivering any certificate representing such fractional
      interest, make a cash payment to the holder of such Debenture of an amount equal to the fractional interest which would have been issuable multiplied by the Current Market Price. Upon request by the Debentureholder, the Corporation shall provide, in
      writing to the Debentureholder, the price to be paid in respect of such fractional Shares.

    

    

    
      	
              5.6

            	
              Corporation to Reserve Shares

            


       

      

    

    The Corporation covenants with the Debentureholder that it will at all times reserve and keep available out of its authorized Shares, solely for the
      purpose of issue upon conversion of this Debenture as in this Article 5 provided, and conditionally allot to the Debentureholder upon the exercise of the conversion rights hereunder, such number of Shares as shall then be issuable upon the conversion
      of all outstanding Debentures. The Corporation covenants with the Debentureholder that all Shares which shall be so issuable shall be duly authorized and validly issued.

              Cancellation of Converted Debentures

            


       

      

    

    Subject to the provisions of Section 5.3(d) as to the partial conversion of this Debenture, converted in part, if this Debenture is converted in whole or
      in part under the provisions of this Article 5 it shall be delivered in accordance with Section 5.3(a) to and cancelled by the Corporation and no Debenture shall be issued in substitution therefor.

    

    

    
      	
              5.8

            	
              Certificate as to Adjustment

            


       

      

    

    The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section
      5.4, deliver an Officer’s Certificate to the Debentureholder 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 specified therein shall be verified by an opinion of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the
      Debentureholder (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest (subject to manifest error). When so approved, the Corporation shall, except in respect of any subdivision, redivision,
      reduction, combination or consolidation of the Shares, forthwith give notice to the Debentureholder in the manner provided in Section 13.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting
      Conversion Price; provided that, if the Corporation has given notice otherwise than under this Section 5.8 covering all the relevant facts in respect of such event, no such notice need be given under this Section 5.8.

    

    

    
      	
              5.9

            	
              Notice of Special Matters

            


       

      

    

    The Corporation covenants with the Debentureholder that so long as this Debenture remains outstanding, it will give notice to the Debentureholder in the
      manner provided in Section 13.2, of its intention to fix a record date for any event referred to in Section 5.4(a), 5.4(b), or 5.4(c) (other than a subdivision, redivision, reduction, combination or consolidation of its Shares) which may give rise to
      an adjustment in the Conversion Price, and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation shall only be required to specify in such
      notice such particulars of such event as shall have been fixed and determined on the date on which such notice is given. Such notice shall be given not less than fourteen (14) days, in each case, prior to such applicable record date.

    

    

     

    ARTICLE 6

        COVENANTS OF THE CORPORATION

     

    The Corporation hereby covenants and agrees with the Debentureholder that:

              To Give Notice of Default

              Preservation of Existence, Etc.

            


       

      

    

    Subject to the express provisions hereof, the Corporation will carry on and conduct its activities, and cause its Subsidiaries, if any, to carry on and
      conduct their businesses, in a proper, efficient and business-like manner and in accordance with prudent business practices and, subject to the express provisions hereof, it will use reasonable commercial efforts to preserve and maintain the
      existence of the Corporation and its Subsidiaries, if any.

    

    

    
      	
              6.4

            	
              Keeping of Books

            


       

      

    

    The Corporation will keep or cause to be kept proper books of record and account, in which full and correct entries, in all material respects, shall be
      made of all financial transactions and the assets and business of the Corporation in accordance with GAAP.

              	(a)	
                The Corporation will use reasonable commercial efforts to maintain the listing of the Shares on the NYSE-A, OTC Markets, Toronto Stock Exchange or a comparable
                  public stock exchange or over the counter market, provided that, for greater certainty, the foregoing covenant shall not prevent or restrict the Corporation from carrying out a transaction to which Article 9 would apply if carried out in
                  compliance with Article 9 even if as a result of such transaction the Shares cease to be listed on a stock exchange or market.

              


         

        	

              	(b)	
                The Corporation will use reasonable commercial efforts to maintain its status as a “reporting issuer”, or the equivalent thereof, not in default of Applicable
                  Securities Laws; provided that, for greater certainty, the foregoing covenant shall not prevent or restrict the Corporation from carrying out a transaction to which Article 9 would apply if carried out in compliance with Article 9 even if
                  as a result of such transaction the Corporation no longer maintains its status as a “reporting issuer”, or the equivalent thereof.

    The Corporation shall deliver to the Debentureholder, within 90 days after the end of each fiscal year of the Corporation, an Officer’s Certificate as to
      the knowledge of such officer who executes the Officer’s Certificate certifying that after reasonable investigation and inquiry, the Corporation has complied with all covenants, conditions or other requirements contained in this Debenture, the
      non-compliance with which would, with the giving of notice, lapse of time or otherwise, constitute an Event of Default hereunder, or if such is not the case, setting forth with reasonable particulars the circumstances of any failure to comply and
      steps taken or proposed to be taken to eliminate such circumstances and remedy such Event of Default, as the case may be.

              (a)

            	
              The Corporation will deliver to the Debentureholder a copy of all quarterly and annual financial statements of the Corporation and the report of
                the Corporation’s Auditors thereon (in the case of annual financial statements) and the associated “Management’s Discussion and Analysis” (collectively, “Financial Reports”) at the same time as they are required to be filed under Applicable Securities Laws. Any such obligation to provide such Financial Reports shall continue in the event that the Corporation
                ceases to be a “reporting issuer” (or its equivalent) as if it had continued to be a “reporting issuer” (or its equivalent). Unless the Corporation advises the Debentureholder in writing otherwise, the Debentureholder shall assume that the
                Corporation is a “reporting issuer” and filing the documents on the Securities and Exchange Commission’s EDGAR website pursuant to this Section. Notwithstanding the foregoing, all Financial Reports will be deemed to have been provided to
                the Debentureholder once filed on the Securities and Exchange Commission’s EDGAR website or any successor system thereto. For greater certainty, the Debentureholder shall have no obligation or responsibility to participate in the
                preparation of, or to review or analyze, any such Financial Reports.

              (b)

            	
              purchase for cancellation any Shares, (other than Shares which the Corporation is obligated to purchase under its equity incentive plans in

      the business for which the meeting was originally convened notwithstanding that they may not represent 40% of the principal amount of the outstanding Debentures. Any business may be brought before or dealt with at an adjourned meeting which might
