      if, during the effectiveness of a Registration Statement

      prospectus included in the Registration Statement no longer compliant with
      the applicable Securities Laws or the requirements of the Securities
      Regulators, after notice containing the facts and legal conclusions relied
      upon from the Company to the Subscriber of the occurrence of such an
      event, make no further sales or other dispositions, or offers therefor, of
      the Warrant Shares under such Registration Statement until the Subscriber

      prospectus complying with the applicable Securities Laws or applicable
      requirements of the Securities Regulators as soon as practicable after
      such notice. The Company shall keep the Subscriber fully informed as to
      the status of the Company’s efforts which shall be prompt and diligent to

All payments of all or any part of the Principal Amount due under this Debenture shall be made only by way of conversions in accordance with the provisions of Section 5 hereof.

Conversion

	
	 	 
	
5.1 		
At any time and from time-to-time after the Issue Date and until the Maturity Date, and provided that the Debenture is then outstanding, some or all of the Principal Amount outstanding at any time shall be converted into
Conversion Units, in whole or in part, as and to the extent that the Company receives Foreign Law Loan Payments.

	
	 	 
	
5.2 		
The Company, with or without prior notice to or request from the Holder, shall effect conversions within five (5) Business Days after receipt of any Foreign Law Loan Payment and the amount of any shortfall, if applicable, as
contemplated in Section 7.4 of this Debenture, below, and shall provide written notice to the Holder thereof by delivering to the Holder a duly completed and executed notice of conversion in the form attached hereto as Appendix A (each a

(each a ”Conversion Date”). The Holder shall not be required to physically surrender the Debenture to the Company unless and until the entire Principal Amount has been converted in the manner specified in this Section 5.2.

	
	 	 
	
5.3 		
Any conversions hereunder shall have the effect of reducing the outstanding Principal Amount in an amount equal to the applicable amount of the Principal Amount being converted. The Company shall maintain records showing all
Principal Amounts converted, the date of such conversions and the outstanding balance of the Principal Amount remaining.

	
	 	 
	
5.4 		
The Holder, by acceptance of the Debenture, acknowledges and agrees that, following each conversion of any portion of the Principal Amount, the unpaid and unconverted Principal Amount will be decreased by the dollar amount of the
product of the number of Conversion Units issued upon conversion and the Conversion Price.

	
	 	 
	
5.5 		
The number of Conversion Units issuable upon any conversion shall be equal to the number obtained by dividing (x) by (y) where (x) is equal to the amount of the Principal Amount to be converted and (y)
is the Conversion Price.

	

	
5.6 		
Not later than ten (10) Business Days after any Conversion Date, the Company will deliver to the Holder certificates representing the number of Conversion Shares and Warrants being issued, which certificates shall bear such
restrictive legends and trading restrictions as are required by applicable laws and by the Exchange.

	
	 	 	 
	
5.7 		
If at any time or from time to time while any Principal Amount is still outstanding, the Company shall effect a subdivision or consolidation of the issued and outstanding Shares, the Conversion Price in effect immediately before a
subdivision shall be proportionately decreased, and, conversely, the Conversion Price in effect immediately before a consolidation shall be proportionately increased. Any adjustment under this Section 5.7 shall become effective at the close of
business on the date the subdivision or consolidation becomes effective.

	
	 	 	 
	
5.8 		
If at any time or from time to time while the Debenture is outstanding, the Company issues, or fixes a record date for the determination of holders of Shares entitled to receive, a cash or other dividend or other distribution
payable solely in Shares, the Conversion Price that is then in effect shall be decreased as of the time of such issuance or, in the event such record date is fixed, as of the close of business on such record date, by multiplying the Conversion Price
by a fraction (i) the numerator of which is the total number of Shares issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (ii) the denominator of which is the sum of the total
number of Shares issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of Shares issuable in payment of such dividend or distribution; provided, however, that if such
record date is fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the
Conversion Price shall be adjusted pursuant to this Section 5.8 to reflect the actual payment of such dividend or distribution.

	
	 	 	 
	
5.9 		
If at any time while the Debenture is outstanding, (i) the Company effects any merger or combination of the Company with or into another entity, (ii) the Company effects any sale of all or substantially all of its assets in one or
more transactions, (iii) any tender offer or exchange offer (whether by the Company or another entity) is completed pursuant to which holders of Shares are permitted to tender or exchange their Shares for other securities, cash or property, or (iv)
the Company effects any reclassification or recapitalization of the Shares or any compulsory share exchange pursuant to which the Shares are effectively converted into or exchanged for other securities, cash or property (other than a subdivision,
consolidation or dividend provided for elsewhere in this Section 5) (in any such case, a “Fundamental Change”), then, upon any subsequent conversion of the Debenture, the Holder shall have the right to receive, for each Conversion
Unit that would have been issuable upon such conversion absent such Fundamental Change, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Change if it had been,
immediately prior to such Fundamental Change, the holder of one Conversion Unit (the ”Alternate Consideration”). If holders of Shares are given any choice as to the securities, cash or property to be received in a Fundamental
Change, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of the Debenture following such Fundamental Change. In the event of a Fundamental Change, the Company or the successor or
purchasing entity, as the case may be, shall execute with the Holder a written agreement providing that:

	
	 	 	 
		
(a) 		
the Debenture shall thereafter entitle the Holder to purchase the Alternate Consideration; and

	
	 	 	 
		
(b) 		
in the case of any such successor or purchasing entity, upon such consolidation, merger, statutory exchange, combination, sale or conveyance, such successor or purchasing entity shall be jointly and severally liable with the
Company for the performance of all of the Company’s obligations under the Debenture and the Subscription Agreement entered into in connection with the issuance of the Debenture.

	

	
5.10 		
If, in the case of any Fundamental Change, the Alternate Consideration includes shares, other securities, other property or assets of an entity other than the Company or any such successor or purchasing entity, as the case may be,
then such written agreement shall also be executed by such other entity and shall contain such additional provisions to protect the interests of the Holder as the board of directors of the Company shall reasonably consider necessary by reason of the
foregoing. At the Holder’s request, any successor to the Company or surviving entity in such Fundamental Change shall issue to the Holder a new debenture consistent with the foregoing provisions and evidencing the Holder’s right to
convert such new debenture into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Change is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section
5 and insuring that the Debenture (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Change.

	
	 	 
	
5.11 		
The Company covenants that it will at all times keep available out of its authorized and unissued Shares, a number of Shares that is sufficient for the purpose of issuance upon conversion of all or any part of the Principal Amount
then outstanding and upon exercise of the Warrants, not less than such number of Shares as shall be issuable upon the conversion of the Principal Amount and upon the exercise of the Warrants. The Company covenants that all Shares that shall be so
issuable shall, upon issue, be duly and validly authorized, issued and fully paid and non-assessable.

	
	 	 
	
5.12 		
No fractional Shares shall be issued upon conversion of all or any part of the Principal Amount under the Debenture. All Shares and Warrants (including fractions thereof) issuable upon conversion of all or any part of the
Principal Amount shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fraction of a Share or Warrant. If, after the aforementioned aggregation, the conversion would result in the issuance of any
fraction of a Share, the Company shall, in lieu of issuing any fraction of a Share, pay cash equal to the product of such fraction multiplied by the fair market value per Share on the date of the conversion (as reported by the Exchange or any other
national securities exchange on which the Shares are then listed for trading, or if none, the most recently reported “over the counter” trade price or if none, as determined in good faith by the board of directors of the Company).

	
	 	 
	
5.13 		
In each case of an adjustment or readjustment of the Conversion Price for the number of Conversion Units issuable upon conversion of all or any part of the Principal Amount then outstanding under the Debenture, the Company, at its
own expense, shall cause its Chief Financial Officer or other officer as directed by the board of directors of the Company to compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such
adjustment or readjustment, and shall deliver such certificate to the Holder in accordance with Section 9.1. The certificate shall set forth such adjustment or readjustment, showing in reasonable detail the facts upon which such adjustment or
readjustment is based. No adjustment in the Conversion Price shall be required to be made unless it would result in an increase or decrease of at least one cent, but any adjustments not made because of this sentence shall be carried forward and
taken into account in any subsequent adjustment otherwise required hereunder.

	
	 	 
	
6. 		
Limitations on Conversion

	
	 	 
	
6.1 		
The Company shall not convert any portion of the Principal Amount pursuant to the terms and conditions of the Debenture to the extent that, after giving effect to such conversion, the Holder together with the Holder’s
Affiliates (as defined in Exchange Policy 1.1) and Persons acting jointly or in concert with such Persons (together, the “Joint Actors”) would beneficially own in excess of 19.9% (the “Maximum Percentage”) of
the number of Shares outstanding immediately after giving effect to such conversion on a partially diluted basis, assuming the conversion of all securities of the Joint Actors which are convertible into Shares within sixty days from the proposed
Conversion Date, including without limitation, the Conversion Shares issuable upon conversion of all or any part of the Principal Amount then outstanding but excluding the Shares issuable upon exercise of Warrants if and to the extent that the
Warrants contain a provision limiting exercise where exercise would cause the Holder to beneficially own in excess of the Maximum Percentage.

	

	7. 	
      Foreign Currency Exchange

	 	 	 
	7.1 	
      At the request of the Holder, the Company has agreed that
      the Holder may pay the monetary consideration for the issue of the
      Debenture to the Argentine Branch and with the Foreign Currency
      Subscription Amount, and that the Argentine Branch will thereafter lend
      the Foreign Currency Subscription Amount to the Foreign Borrower pursuant
      to the Foreign Law Loan. In consideration of the Company agreeing to such
      payment, the Holder hereby assumes and shall bear all risk, foreseen or
      unforeseen, that the Company or the Argentine Branch may incur losses by
      accepting such payment in Foreign Currency, including risks associated
      with any failure to repay the Foreign Law Loan and risks associated with
      fluctuations in foreign currency exchange rates and any devaluation of the
      Foreign Currency, and shall indemnify the Company against any losses
      caused by such; provided, however, that the Holder shall be permitted to
      credit, against amounts due pursuant to such indemnity, the amount of any
      Conversion Penalty. Notwithstanding the foregoing, this indemnity shall
      not extend to banking or exchange rate risk loss suffered by the Company
      through its Argentine Branch in respect of all or any portion of a timely
      payment on account of the Foreign Law Loan where the loss is due to a
      change in the foreign exchange rate, a banking failure or a change in the
      applicable laws, rules, or regulation affecting Argentine banks and
      financial institutions that occurs after the date of receipt. For clarity,
      once the Company receives timely payment on account of the Foreign Law
      Loan either from the Borrower or the Guarantor, the Company shall assume
      the risk – but only as to the amount of that payment – that all or any
      part of that payment is subsequently devalued by virtue of foreign
      exchange fluctuations or other banking failure.

	 	 	 
	7.2 	
      Upon receipt, the Argentine Branch will loan the entire
      Foreign Currency Subscription Amount to the Foreign Borrower pursuant to
      the Foreign Law Loan Agreement, which will include provisions permitting
      the Argentine Branch to be repaid in installments on specified Foreign Law
      Loan Payment Dates. Within five (5) Business Days after a Foreign Law Loan
      Payment Date, the Company will effect a conversion pursuant to the terms
      of the Debenture.

	 	 	 
	7.3 	
      Notwithstanding the foregoing, if:

	 	 	 
		(a) 	
      the Foreign Borrower and the Guarantor are unable to
      repay any amounts due under the Foreign Law Loan Agreement, other than due
      to public holiday, computer failure or other work place disruption (unless
      such disruption exists for five Business Days or more) pursuant to the
      terms of the Foreign Law Loan Agreement and the Guaranty, respectively;
      or

	 	 	 
		(b) 	
      there is an Event of Default under the Foreign Law Loan
      Agreement of the type specified in Section VI(a), (d), (f) or (h) of the
      Foreign Law Loan Agreement, or the Foreign Law Loan Agreement is
      unenforceable by the Argentine Branch, and the Guarantor has not paid the
      amounts due thereunder pursuant to the Guaranty within ten (10) Business
      Days after notice (as and to the extent that notice is required under the
      terms of the Guaranty),

	 	 	 
			
      the Company may, at its sole discretion, elect to cause
      the Argentine Branch to assign and transfer, without

	 	 	 
		
      recourse, the Company’s interest in the Foreign Law Loan
      Agreement and the moneys owed to it thereunder to the Holder and such
      assignment and transfer shall constitute full and final repayment of the
      sum of the Principal Amount and any other amounts owed pursuant to this
      Convertible Debenture, and this Convertible Debenture shall thereupon be
      cancelled.

	 	 	 
	7.4 	
      Until such time as the Foreign Currency Holdings equal
      zero, the Holder shall indemnify and hold harmless the Company and the
      Argentine Branch from any losses incurred by them (or either of them) if,
      on any Conversion Date, the Conversion Exchange Rate is less than the
      Subscription Date Exchange Rate and, without limiting the foregoing and as
      a condition precedent to the completion of any conversion hereunder, the
      Holder shall immediately pay such additional amount in Foreign Currency as
      may be necessary to compensate Argentine Branch for the shortfall, such
      amount to be net of any interest received by the Argentine Branch under
      the Foreign Law Loan Agreement and not otherwise applied to any previous
      shortfall and provided further that the Holder shall be permitted to
      credit, against amounts due pursuant to such indemnity, the amount of any
      Conversion Penalty.

	8. 	
      Events of Default

	 	 	 
	8.1 	
      The occurrence of any of the following shall constitute
      an “Event of Default” under the Debenture:

	 	 	 
		(a) 	
      the Company not complying with the payment and conversion
      proceedings and obligations set forth in Sections 4 and 5 of this
      Debenture and/or failing to pay any Principal Amount on the due date
      hereunder and such failure continuing for ten (10) Business Days after
      written notice thereof is delivered to the Company unless the Company
      cannot convert the Principal Amount because of the ownership limitation
      imposed pursuant to Section 6;

	 	 	 
		(b) 	
      the Company failing to observe or perform any other
      covenant or agreement contained in the Debenture or the Subscription
      Agreement which failure is not cured, if possible to cure, within thirty
      (30) calendar days after notice of such default is sent by the Holder to
      the Company;

	 	 	 
		(c) 	
      the Company or the Argentine Branch (i) applying for or
      consenting to the appointment of a receiver, trustee, liquidator or
      custodian of itself or of all or a substantial part of its property, (ii)
      being unable, or admitting in writing its inability, to pay its debts
      generally as they mature or become due, (iii) making a general assignment
      for the benefit of its or any of its creditors or making a proposal or
      otherwise taking advantage of any provisions for relief under the
      Bankruptcy and Insolvency Act (Canada), the Companies Creditors'
      Arrangement Act (Canada) or similar legislation in any jurisdiction,
      (iv) being dissolved or liquidated in full or in part, (v) commencing a
      voluntary case or other proceeding seeking liquidation, reorganization or
      other relief with respect to itself or its debts under any bankruptcy,
      insolvency or other similar law now or hereafter in effect or consenting
      to any such relief or to the appointment of or taking possession of its
      property by any official in an involuntary case or other proceeding
      commenced against it, or (vi) taking any action for the purpose of
      effecting any of the foregoing; and

	 	 	 
		(d) 	
      proceedings for the appointment of a receiver, manager or
      receiver-manager, trustee, liquidator or custodian of the Company and/or
      the Argentine Branch or of all or a substantial part of the property
      thereof, or an involuntary case or other proceedings seeking liquidation,
      reorganization or other relief with respect to the Company and/or the
      Argentine Branch or the debts thereof under any bankruptcy, insolvency or
      other similar law now or hereafter in effect being commenced and an order
      for relief entered or such proceeding is not dismissed or discharged
      within thirty (30) days of commencement.

	 	 	 
	8.2 	
      Upon the occurrence or existence of any Event of Default
      and following the expiry of any applicable grace periods and at any time
      thereafter during the continuance of such Event of Default, the Holder
      may, by written notice to the Company, declare all outstanding amounts
      payable by the Company hereunder to be immediately due and payable without
      presentment, demand, protest or any other notice of any kind, all of which
      are hereby expressly waived, anything contained herein to the contrary
      notwithstanding. Upon the occurrence or existence of any Event of Default
      described in subsection 8.1(c) hereof, immediately and without notice, all
      outstanding amounts payable by the Company hereunder shall automatically
      become immediately due and payable, without presentment, demand, protest,
      notice of dishonour or any other notice of any kind, all of which are
      hereby expressly waived, anything contained herein to the contrary
      notwithstanding. The Company hereby waives: (a) marshaling of assets and
      liabilities; (b) sale in inverse order of alienation; (c) notice of
      acceptance; and (d) all rights the Company may have under any applicable
      suretyship law. In addition to the foregoing remedies, upon the occurrence
      or existence of any Event of Default, the Holder may exercise any other
      right, power or remedy permitted to it by law, either by suit in equity or
      by action at law, or both.
