(ii)

Notwithstanding subparagraph 1(d)(i) or any other provision of this Debenture, at any time following the expiry of six months after the date of the Purchase Agreement, provided that no Event of Default has then occurred and is continuing, upon twenty (20) Trading Days’ prior notice in writing to the Holder, which notice shall set out particulars of the principal amount being prepaid, the date of prepayment and the prepayment price (a “Prepayment Notice”), the Company shall be entitled to prepay:

(1)

all or any portion of the principal amount outstanding under this Debenture out of the proceeds of any equity financing; and

2.

CONVERSION OF DEBENTURES.  This Debenture shall be convertible into validly issued, fully paid and non-assessable Common Shares, on the terms and conditions set forth in this Section 2.  

(a)

Voluntary Conversion. This Debenture shall be convertible, in whole or in part, into Common Shares at the option of the Holder, at any time and from time to time (subject to the conversion limitations set forth in Section 2(c)(ix)).  The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein the principal amount of this Debenture to be converted and, if the Holder determines in its sole discretion to convert such accrued and unpaid interest (or a portion thereof), the amount of accrued and unpaid interest thereon to be converted and the date on which such conversion shall be effected (such date, the “Conversion Date”); provided that a Holder may only convert the portion of the accrued interest

3

that corresponds to the principal being converted.  If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered hereunder.  To effect conversions hereunder, the Holder shall not be required to physically surrender this Debenture to the Company unless the entire principal amount of this Debenture, plus all accrued and unpaid interest thereon, has been so converted or otherwise been repaid to the Holder.  Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Debenture in an amount equal to the principal amount converted in such conversion.  The Holder and the Company shall maintain records showing the principal amount(s) converted and the date of such conversion(s).  In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder, and any assignee by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Debenture, the unpaid and unconverted principal amount of this Debenture may be less than the amount stated on the face hereof.

(b)

Conversion Price.  The Conversion Price in effect on any Conversion Date shall be equal to $0.98 and shall be subject to adjustment as provided in Section 3 (the “Conversion Price”).

(c)

Mechanics of Conversion.

(i)

Conversion Shares Issuable Upon Conversion of Debenture.  The number of Conversion Shares issuable upon a conversion hereunder shall be determined by the quotient obtained by dividing (x) the sum of (a) the outstanding principal amount of this Debenture to be converted and (b) at the option of the Holder, a portion or all of any accrued and unpaid interest on this Debenture to be converted by (y) the Conversion Price.

(ii)

Delivery of Certificate Upon Conversion. Not later than forty-eight (48) hours over two (2) Trading Days (and, where the Conversion Notice was delivered after 4:00 p.m. on a Trading Day, by no later than 10 a.m. on the third (3^rd) Trading Day) after each Conversion Date (the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates representing the Conversion Shares which, on a Legend Removal Qualification Event shall be free of restrictive legends and trading restrictions representing the number of Conversion Shares being acquired upon the conversion of this Debenture and (B) if the Holder elects not to convert the accrued and unpaid interest on this Debenture (or a portion thereof) to be converted, a bank check in the amount of such accrued and unpaid interest.  If (i) there is an effective registration statement permitting the issuance of Conversion Shares to or resale of the Conversion Shares by the Holder or (ii) following the six month anniversary of the Original Issue Date, the Conversion Shares are eligible for sale under Rule 144 without volume or manner-of-sale restrictions and as of such date the Company is in compliance with the current public information required under Rule 144 as to such Conversion Shares, the Company shall deliver any certificate or certificates required to be delivered by the Company under this Section 2(c) by causing such certificates to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian (“DWAC”) system. The Holder shall be entitled to require the Company to deliver Conversion Shares and/or Common Shares

4

issuable pursuant to Section 5(e) to and in the name of one or more Affiliates of the Holder in accordance with the Holder’s written instructions.   

(iii)

Failure to Deliver Certificates.  If, in the case of any Notice of Conversion, such certificate or certificates are not credited to the account of the Holder’s broker with The Depository Trust Company through its DWAC system or delivered to or as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Company at any time on or before such crediting or its receipt of such certificate or certificates, to rescind such Conversion, in which event the Company shall promptly return to the Holder any original Debenture delivered to the Company and the Holder shall promptly return to the Company the Common Shares certificates (or any Common Shares received electronically) issued to such Holder pursuant to the rescinded Conversion Notice.

(iv)

Obligation Absolute; Partial Liquidated Damages.  The Company’s obligations to issue and deliver the Conversion Shares upon conversion of this Debenture in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of such Conversion Shares.  In the event the Holder of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse conversion based on any claim by the Company or any Affiliate thereof that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining conversion of all or part of this Debenture shall have been sought and obtained, and the Company posts a surety bond for the benefit of the Holder in the amount of 150% of the outstanding principal amount of this Debenture, which is subject to the injunction, which bond shall remain in effect until the completion of litigation of the underlying dispute and the proceeds of which shall be payable to the Holder to the extent it obtains judgment.  In the absence of such injunction, the Company shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion.  If the Company fails when required hereunder for any reason to deliver to the Holder such certificate or certificates pursuant to Section 2(c)(ii) by the second Trading Day following the Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount being converted, $5 per Trading Day (increasing to $10 per Trading Day on the fourth (4^th) Trading Day after such liquidated damages begin to accrue) for each Trading Day commencing on the second Trading Day after such Share Delivery Date until such certificates are delivered or Holder rescinds such conversion.  Nothing herein shall limit the Holder’s right to pursue actual damages or declare an Event of Default (as defined below) pursuant to Section 4 hereof for the Company’s failure to deliver Conversion Shares within the period specified herein and the Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.  The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

5

(v)

Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion.  In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery Date pursuant to Section 2(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, Common Shares to deliver in satisfaction of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in addition to any other remedies available to or elected by the Holder) the amount, if any, by which (x) the Holder’s total purchase price (including any brokerage commissions) for the Common Shares so purchased exceeds (y) the product of (1) the aggregate number of Common Shares that the Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the Holder, either reissue (if surrendered) this Debenture in a principal amount equal to the principal amount of the attempted conversion (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number of Common Shares that would have been issued if the Company had timely complied with its delivery requirements under Section 2(c)(ii).  The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In.  Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Common Shares upon conversion of this Debenture as required pursuant to the terms hereof.

(vi)

Reservation of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued Common Shares for the sole purpose of issuance upon conversion of this Debenture, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the other holders of the Debentures), not less than such aggregate number of Common Shares as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 3) upon the conversion of the then outstanding principal amount of this Debenture.  The Company covenants that all Common Shares that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and non-assessable and, if the Registration Statement is then effective under the Securities Act, shall be registered for public resale in accordance with such Registration Statement (subject to such Holder’s compliance with its obligations under the Registration Rights Agreement).

(vii)

Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Debenture.  As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Company shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

6

(viii)

Transfer Taxes.  The issuance of certificates for the Common Shares on conversion of this Debenture shall be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates.

(ix)

Holder’s Conversion Limitations.  The Company shall not effect any conversion of this Debenture, and a Holder shall not have the right to convert any portion of this Debenture, to the extent that after giving effect to the conversion set forth on the applicable Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with the Holder or any of the Holder’s Affiliates) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  To the extent that the limitation contained in this Section 2(c)(ix) applies, the determination of whether this Debenture is convertible (in relation to other securities owned by the Holder together with any Affiliates) and of which principal amount of this Debenture is convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether this Debenture may be converted (in relation to other securities owned by the Holder together with any Affiliates) and which principal amount of this Debenture is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of such determination.  In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.  For purposes of this Section 2(c)(ix), in determining the number of outstanding Common Shares, the Holder may rely on the number of outstanding Common Shares as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the SEC, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer agent setting forth the number of Common Shares outstanding.  Upon the written or oral request of a Holder, the Company shall within two (2) Trading Days confirm orally and in writing to the Holder the number of Common Shares then outstanding.  In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Debenture, by the Holder or its Affiliates since the date as of which such number of outstanding Common Shares was reported. The “Beneficial Ownership Limitation” shall be all of the following: (i) 4.9% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares upon conversion of this Debenture held by the Holder calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder; (ii) 9.9% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares upon conversion of this Debenture held by the Holder calculated in accordance with Sections 102 and 102.1 of Part XX of the Securities Act (Ontario); and (iii) 19.9% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares upon conversion of this Debenture held by the Holder calculated in accordance with the definition of “Beneficial Ownership” in Section 1.1(e) of the Shareholder Rights Plan Agreement of the Company dated as of November 25, 2011, as amended or amended and restated from time to time.  The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease (provided that, in no case may the Holder decrease the

7

Beneficial Ownership Limitation below 4.9%) the Beneficial Ownership Limitation provisions of this Section 2(c)(ix), provided that the Beneficial Ownership Limitation in no event exceeds 19.9% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares upon conversion of this Debenture held by the Holder and the Beneficial Ownership Limitation provisions of this Section 2(c)(ix) shall continue to apply.  Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Company.  The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(c)(ix) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation.  The limitations contained in this paragraph shall apply to a successor holder of this Debenture.

3.

Certain Adjustments.

(a)

Stock Dividends and Stock Splits.  If the Company, at any time while this Debenture is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in Common Shares on the Common Shares or any Common Share Equivalents, (ii) subdivides the outstanding Common Shares into a larger number of shares, (iii) combines (including by way of a reverse stock split) the outstanding Common Shares into a smaller number of shares or (iv) issues, in the event of a reclassification of the Common Shares, any shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares (excluding any treasury shares of the Company) outstanding immediately before such event, and of which the denominator shall be the number of Common Shares outstanding immediately after such event.  Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b)

Subsequent Rights Offerings.  If the Company, at any time while this Debenture is outstanding, shall issue rights, options or warrants to all holders of the Common Shares entitling them to subscribe for or purchase Common Shares (the “Purchase Rights”), then, upon any conversion of this Debenture, the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights that the Holder could have acquired if the Holder had held the number of Conversion Shares issued upon such conversion of this Debenture immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of the Common Shares are to be determined for the grant, issue or sale of such Purchase Rights; provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation.

8

(c)

Pro Rata Distributions. If the Company, at any time while this Debenture is outstanding, shall distribute to all holders of Common Shares evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security other than Common Shares (a “Distribution”), then, upon any conversion of this Debenture, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Conversion Shares issued upon such conversion of this Debenture immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the participation in such Distribution.

(d)

Fundamental Transaction. If, at any time while this Debenture is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Shares are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Shares, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Shares or any compulsory share exchange pursuant to which the Common Shares are effectively converted into or exchanged for other securities, cash or property, (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding Common Shares (not including any Common Shares held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion of this Debenture, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 2(c) on the conversion of this Debenture), the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Shares for which this Debenture is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(c) on the conversion of this Debenture).  For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) Common Share in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration.  If holders of Common Shares are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Debenture following such Fundamental Transaction.  The Company shall cause any successor entity in a Fundamental Transaction in

9

which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Debenture and the other Transaction Documents in accordance with the provisions of this Section 3(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction.  Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Debenture and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Debenture and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein, except, in any case and notwithstanding anything to the contrary contained herein, that with respect to the conversion of this Debenture, the Holder shall only be entitled to receive the Alternate Consideration upon any conversion hereof subsequent to the consummation of a Fundamental Transaction.

(e)

Adjustment Upon Issuance of Common Shares.

(i)

Dilutive Issuances. If and whenever on or after the Original Issue Date, the Company issues or sells, or in accordance with this Section 3(e) is deemed to have issued or sold, any Common Shares (including the issuance or sale of Common Shares owned or held by or for the account of the Company, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold and any issuances of Common Shares or Common Share Equivalents covered by Sections 3(a) through (d)) for a consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such issue or sale or deemed issuance or sale (such Conversion Price then in effect is referred to as the “Applicable Price” and such issuance, a“Dilutive Issuance”), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Conversion Price and consideration per share under this Section 3(e)(i)), clauses (ii) through (vi) of this Section 3(e) shall be applicable.

(ii)

Issuance of Options. If the Company in any manner grants or sells any Options (other than Excluded Securities) and the lowest price per share for which one Common Share is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share.  For purposes of this Section 3(e)(ii), the “lowest price per share for which one Common Share is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one Common Share upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option and (y) the lowest exercise price set forth in such Option for which one Common Share is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon

10

exercise of any such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person).  Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Share or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Share upon conversion, exercise or exchange of such Convertible Securities.

(iii)

Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities (other than Excluded Securities) and the lowest price per share for which one Common Share is issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share.  For the purposes of this Section 3(e)(iii), the “lowest price per share for which one Common Share is issuable upon the conversion, exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one Common Share upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one Common Share is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or any other Person).  Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Share upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price has been or is to be made pursuant to other provisions of this Section 3(e), except as contemplated below, no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

(iv)

Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for Common Shares increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold.  For purposes of this Section 3(e)(iv), if the terms of any Option or Convertible Security that was outstanding as of the Original Issue Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Shares deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease.

11

No adjustment pursuant to this Section 3(e)(iv) shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

(v)

Calculation of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (the “Primary Security” and such Option, Convertible Security, and/or Adjustment Right, a “Secondary Security”), together comprising one integrated transaction, the Primary Security issued or sold in such integrated transaction shall be deemed to have been issued for consideration equal to the difference of (A) the aggregate consideration received by the Company to purchase such Primary Security and each such Option (as applicable) and/or Convertible Security (as applicable) and/or Adjustment Right (as applicable), minus (B) the product of (x) the sum of the Black Scholes Consideration Value of each such Option and/or Convertible Security (as applicable) and/or Adjustment Right (as applicable) on a per share basis multiplied by (y) the aggregate number of Common Shares issued or issuable pursuant to such Option and/or Convertible Security (as applicable) and/or Adjustment Right (as applicable).  If any Common Shares, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor (for the purpose of determining the consideration paid for such Common Shares, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to be the gross amount of consideration received by the Company therefor.  If any Common Shares, Options or Convertible Securities are issued or sold for a consideration other than cash (for the purpose of determining the consideration paid for such Common Shares, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company for such securities will be the arithmetic average of the VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of receipt.  If any Common Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity (for the purpose of determining the consideration paid for such Common Shares, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Shares, Options or Convertible Securities, as the case may be.  The fair value of any consideration other than cash or publicly traded securities (for the purpose of determining the consideration paid for such Common Shares, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be determined by the Company and the Holder.  If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10^th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder.  The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

(vi)

Record Date. If the Company takes a record of the holders of the Common Shares for the purpose of entitling them (A) to receive a dividend or other distribution

12

payable in Common Shares, Options or in Convertible Securities or (B) to subscribe for or purchase Common Shares, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Common Shares deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be).

(f)

Holder's Right of Alternative Conversion Price Following Issuance of Certain Options or Convertible Securities. In addition to and not in limitation of the other provisions of this Section 3, if the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Shares, Options or Convertible Securities other than Excluded Securities (any such securities, “Variable Price Securities”) after the Original Issue Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for Common Shares pursuant to such Options or Convertible Securities, as applicable, at a price which varies or may vary with the market price of the Common Shares, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations and share dividends) (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via facsimile and overnight courier to the Holder on the date of such agreement and/or the issuance of such Convertible Securities or Options, as applicable.  From and after the date the Company enters into such agreement or issues any such Variable Price Securities, the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of this Debenture by designating in the Conversion Notice delivered upon any conversion of this Debenture that solely for purposes of such conversion the Holder is relying on the Variable Price rather than the Conversion Price then in effect.  The Holder’s election to rely on a Variable Price for a particular conversion of this Debenture shall not obligate the Holder to rely on a Variable Price for any future conversion of this Debenture.

(g)

Calculations.  All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.  For purposes of this Section 3, the number of Common Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Common Shares (excluding any treasury shares of the Company) issued and outstanding.

(h)

Notice to the Holder.

(i)

Adjustment to Conversion Price.  Whenever the Conversion Price is adjusted pursuant to any provision of this Section 3, the Company shall within ten (10) calendar days of such adjustment deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.  

(ii)

Notice to Allow Conversion by Holder.  If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Shares, (C) the Company shall authorize the granting to all holders of the Common Shares of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any

13

rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Shares, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Shares are converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of this Debenture, and shall cause to be delivered to the Holder at its last address as it shall appear upon the Debenture Register, at least ten (10) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Shares of record shall be entitled to exchange their Common Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice.  To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the SEC pursuant to a Current Report on Form 8-K.  

4.

5.

REDEMPTION.

(a)

Optional Redemption Right of the Holder.

(i)

Commencing on March 1, 2015, the Holder shall have the right, at its option, to require the Company to redeem up to $750,000 of principal (plus accrued and unpaid interest thereon) (the “Monthly Allowance”) per calendar month (the “Holder Redemption Right”).  The Holder may exercise its Holder Redemption Right for a calendar month, at any time and from time to time, during such calendar month, by sending one or more written notices to the Company (each a “Holder Redemption Notice”) by not later than 11:59:59 P.M. (local time in New York City, New York) on the last Trading Day of such calendar month, which Holder Redemption Notices shall specify the principal amount to be redeemed and the amount of accrued and unpaid interest thereon (together, the “Holder Redemption Amount”).  The Company shall promptly, but in any event no more than two (2) Trading Days after the date that the Holder delivers a Holder Redemption Notice to the Company (the “Holder Redemption Payment Date”), pay the applicable Holder Redemption Amount (1) in cash by wire transfer of immediately available funds to the extent that this Debenture is Stock Off (as defined below) on the date that the Holder delivers the Holder Redemption Notice to the Company or (2) Common Shares to the extent that this Debenture is Stock On (as defined below) on the date that the Company delivers the Holder Redemption Notice to the Company in accordance with Section 5(e) below.  For the avoidance of doubt, payment in cash or Common Shares shall be determined according to the status of the Debenture as Stock On or Stock Off on the date that the Holder delivers the Holder Redemption Notice to Company and not the Holder Redemption Payment Date.  For the further avoidance of doubt, the Holder and the Company agree that the Holder may deliver more than one Holder Redemption Notice during a calendar month provided that the sum of the Holder Redemption Amounts set forth in all of the Holder Redemption Notices delivered during such calendar month does not exceed the Monthly Allowance.

17

(b)

At any time, and from time to time, subject to the provisions of this Section 5, the Company may deliver a written notice to the Holder that it will pay any Holder Redemption Amounts under Section 5(a)(i) in Common Shares (a “Stock On Notice”) and any such notice shall become effective on the second (2^nd) Trading Day after the Holder’s receipt thereof (the “Stock On Effective Date”).  Such Stock On Notice shall certify that the Equity Conditions are satisfied and at any time that this Debenture is Stock On, the Company shall, upon the Holder’s request, certify in writing to the Holder that the Equity Conditions are satisfied.  From the time that a Stock On Notice takes effect until such time that such Stock On Notice is withdrawn pursuant to Section 5(d) or deemed withdrawn pursuant to Section 5(c), this Debenture shall be deemed to be “Stock On.”  At any time that this Debenture is not Stock On, then this Debenture shall be deemed to be “Stock Off.”  For the avoidance of doubt, the Holder may deliver a Holder Redemption Notice during the period after receipt of the Stock On Notice but prior to the Stock On Effective Date; the Debenture shall be Stock Off during such period and, accordingly, the applicable Holder Redemption Amount would be payable in cash.  

(c)

The Company may not deliver a Stock On Notice unless the Equity Conditions are then satisfied.  If the Equity Conditions cease, for any reason, to be satisfied while this Debenture is Stock On, then the applicable Stock On Notice shall, automatically without any further action of the Company or the Holder, immediately be deemed to be withdrawn and this Debenture shall immediately be deemed to be Stock Off (an “Equity Conditions Failure”).  The Company shall immediately notify the Holder of any Equity Conditions Failure.  

(d)

The Company may voluntarily withdraw a Stock On Notice by delivering a written notice (a “Stock Off Notice”) to the Holder and such Stock On Notice shall be deemed withdrawn and this Debenture shall be Stock Off two (2) Trading Days after receipt thereof by the Holder (the “Voluntary Stock Off Effective Date”).  For the avoidance of doubt, the Holder may deliver a Holder Redemption Notice during the period after receipt of the Stock Off Notice but prior to the Voluntary Stock Off Effective Date; the Debenture shall be Stock On during such period and, accordingly, the applicable Holder Redemption Amount would be payable in Common Shares on the applicable Holder Redemption Payment Date as provided herein.  

(e)

With respect to each Holder Redemption Notice delivered to the Company pursuant to Section 5(a)(i) at a time when this Debenture was Stock On, subject to the provisions of this Section 5(e), the Company shall, in payment of the Holder Redemption Amount deliver to the Holder a number of Common Shares equal to the quotient of (such quotient of (x) and (y), the “Stock Payment Price”) (x) the applicable Holder Redemption Amount and (y) ninety percent (90%) of the arithmetic average of each of the five (5) lowest daily VWAPs for the Common Shares during the twenty (20) Trading Days immediately prior to the date of the Holder Redemption Notice (the “Pricing Period”) by not later than the applicable Holder Redemption Payment Date.  Notwithstanding the foregoing or any other provision herein to the contrary:

(A)

in the event any Equity Conditions Failure occurs after the delivery of the applicable Holder Redemption Notice at a time when this Debenture is Stock On but prior to the applicable Holder Redemption Payment Date, the Company shall pay to the Holder an amount in cash equal to the product of (i) the applicable Holder

18

Redemption Amount divided by Stock Payment Price and (ii) the highest VWAP for the Common Shares during the applicable Pricing Period (such product of (i) and (ii), the “Stock Replacement Payment”);

(B)

in the event that the aggregate number of Common Shares to be delivered to the Holder pursuant to this Section 5(e) in respect of any individual Holder Redemption Notice would cause such Holder to exceed the Beneficial Ownership Limitation, then, (I) the Holder shall provide written notice to the Company that such delivery of all or a portion of such Common Shares would cause Holder to exceed the Beneficial Ownership Limitation, and (II) in addition to delivery of the number of Common Shares that would not cause such Holder to exceed the Beneficial Ownership Limitation, the Company shall pay to the Holder in lieu of such number of Common Shares that would cause the Holder to exceed the Beneficial Ownership Limitation (such excess number of shares, the “Excess Shares”), not more than the later of (x) the Holder Redemption Payment Date and (y) one (1) Trading Day after the date of the Holder’s written notice, an amount in cash equal to the portion of the Holder Redemption Amount that would otherwise be payable in respect of the Excess Shares;

(C)

in the event that the Holder Redemption Amount in respect of any Holder Redemption Notice would exceed the Dollar Volume Limitation, then the Company shall pay the portion of the Holder Redemption Amount that would be in excess of the Dollar Volume Limitation in cash;  

(D)

the event that the aggregate number of Common Shares to be delivered to the Holder pursuant to this Section 5(e) in respect of any individual Holder Redemption Notice would cause the Holder’s Authorized Share Allocation and/or Exchange Cap Allocation to be exceeded, then that portion of such number of Common Shares that would not exceed the Holder’s Authorized Share Allocation and/or Exchange Cap Allocation shall be delivered to the Holder in Common Shares as provided above and the Company shall pay to the Holder, not later than the applicable Holder Redemption Payment an amount in cash equal to the Stock Replacement Payment in lieu of the portion of the applicable Holder Redemption Amount that would cause the Holder’s Authorized Share Allocation and/or Exchange Cap Allocation to be exceeded.

Any Common Shares required to be delivered by the Company to the Holder under this Section 5(e) shall be credited to the Holder’s or its designee’s balance account with Depository Trust Company through its DWAC system on the Holder Redemption Payment Date and free of any restrictive legends under the Securities Act or otherwise.  In addition, the provisions of Section 2(c)(iv) and Section 2(c)(v) shall apply to the delivery of Common Shares under this Section 5(e) mutatis mutandis as if each date when Common Shares are required to be delivered under this Section 5(e) was a Share Delivery Date.

(f)

Notwithstanding anything contained herein to the contrary, the Holder may convert any Holder Redemption Amount pursuant to Section 2 hereof at any time prior to the applicable Holder Redemption Payment Date.  

19

(g)

Redemption Right upon a Change of Control.  No later than ten (10) Trading Days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile, e-mail and overnight courier to the Holder (a “Change of Control Notice”).  At any time during the period beginning after the Holder’s receipt of a Change of Control Notice or the Holder becoming aware of a Change of Control if a Change of Control Notice is not delivered to the Holder in accordance with the immediately preceding sentence (as applicable) and ending on the later of twenty (20) Trading Days after (A) consummation of such Change of Control or (B) the date of receipt of such Change of Control Notice, the Holder may require the Company to redeem all or any portion of this Debenture by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company, which Change of Control Redemption Notice shall indicate the principal amount of this Debenture that the Holder is electing to redeem.  The portion of this Debenture subject to redemption pursuant to this Section 5(g) shall be redeemed by the Company in cash at a price equal to one-hundred ten present (110%) of the principal amount being redeemed plus all accrued and unpaid interest and late charges (the “Change of Control Redemption Price”) and such Change of Control Redemption Price shall be due and payable in cash not later than the later of (x) two (2) Trading Days after the consummation of such Change of Control and (y) the Company’s receipt of the Change of Control Redemption Notice.  Redemptions required by this Section 5(g) shall have priority to payments to holders of the Common Shares in connection with such Change of Control.  Notwithstanding anything to the contrary in this Section 5(g), but subject to Section 2(c)(ix), until the Change of Control Redemption Price is paid in full, the principal amount of this Debenture submitted for redemption under this Section 5(g) (together with any accrued and unpaid interest thereon) may be converted, in whole or in part, by the Holder into Common Shares pursuant to Section 2 and Section 3(d), to the extent applicable.

(h)

Permitted Project Financing.  At least ten (10) Trading Days prior to the consummation of any Permitted Project Financing, but not prior to the public announcement thereof, the Company shall deliver written notice thereof via facsimile, e-mail and overnight courier to the Holder (a “Permitted Project Financing Notice”).  At any time during the period beginning after the Holder’s receipt of a Permitted Project Financing Notice or the Holder becoming aware of any Permitted Project Financing if a Permitted Project Financing Notice is not delivered to the Holder in accordance with the immediately preceding sentence (as applicable) and ending on the later of twenty (20) Trading Days after (A) consummation of such Permitted Project Financing or (B) the date of receipt of such Permitted Project Financing, the Holder may require the Company to redeem all or any portion of this Debenture by delivering written notice thereof (“Permitted Project Financing Redemption Notice”) to the Company, which Permitted Project Financing Redemption Notice shall indicate the principal amount of this Debenture that the Holder is electing to redeem.  The portion of this Debenture subject to redemption pursuant to this Section 5(h) shall be redeemed by the Company in cash at a price equal to one-hundred five present (105%) of the principal amount being redeemed plus all accrued and unpaid interest and late charges (the “Permitted Project Financing Redemption Price”) and such Permitted Project Financing Redemption Price shall be due and payable in cash not later than the later of (x) concurrently with the consummation of such Permitted Project Financing and (y) the Company’s receipt of the Permitted Project Financing Redemption Notice.  Notwithstanding anything to the contrary in this Section 5(h), but subject to Section 2(c)(ix), until the Permitted Project Financing Redemption Price is paid in full, the principal amount of

20

this Debenture submitted for redemption under this Section 5(h) (together with any accrued and unpaid interest thereon) may be converted, in whole or in part, by the Holder into Common Shares pursuant to Section 2.

6.

NONCIRCUMVENTION.  The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined in the Purchase Agreement), Bylaws (as defined in the Purchase Agreement) or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Debenture, and will at all times in good faith carry out all of the provisions of this Debenture and take all action as may be required to protect the rights of the Holder of this Debenture.  Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any Common Shares receivable upon conversion of this Debenture above the Conversion Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable Common Shares upon the conversion of this Debenture, and (iii) shall, so long as any of the Debentures are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued Common Shares, solely for the purpose of effecting the conversion of the Debentures, the maximum number of Common Shares as shall from time to time be necessary to effect the conversion of the Debentures then outstanding (without regard to any limitations on conversion).

7.

RESERVATION OF AUTHORIZED SHARES; EXCHANGE CAP.  

(a)

Reservation.  The Company shall initially reserve out of its authorized and unissued Common Shares a number of Common Shares for each of the Debentures equal to two-hundred twenty five percent (225%) of the entire Conversion Rate with respect to the entire outstanding principal amount of each such Debenture as of the Original Issue Date.  So long as any of the Debentures are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Shares, solely for the purpose of effecting the conversion of the Debentures and other issuances hereunder, including Section 5, two-hundred twenty five percent (225%) of the number of Common Shares as shall from time to time be necessary to effect the conversion of all of the Debentures then outstanding(the “Required Reserve Amount”), provided that at no time shall the number of Common Shares so reserved be less than the number of shares required to be reserved by the previous sentence (without regard to any limitations on conversions).  The initial number of Common Shares reserved for issuance hereunder and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Debentures based on the outstanding principal amount of the Debentures held by each holder on the Original Issue Date or the date of the increase in the number of reserved shares (as the case may be) (the Holder’s pro rata portion of the initial Common Shares reserved for issuance and of each increase thereof as provided herein, the Holder’s “Authorized Share Allocation”).  In the event that a holder shall sell or otherwise transfer any of such holder’s Debentures, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation.  Any Common Shares reserved and allocated to any Person which ceases to hold any Debentures shall be allocated to the remaining holders of Debentures, pro rata based on the principal amount of the Debentures then held by such holders.    

21

(b)

Insufficient Authorized Shares.  If, notwithstanding Section 7(a), and not in limitation thereof, at any time while any of the Debentures remain outstanding the Company does not have a sufficient number of authorized and unreserved Common Shares to satisfy its obligation to reserve for issuance upon conversion of the Debentures or other issuances of Common Shares hereunder at least a number of Common Shares equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized Common Shares to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Debentures then outstanding.  Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than seventy five (75) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized Common Shares.  In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized Common Shares and to cause its board of directors to recommend to the stockholders that they approve such proposal.  

(c)

Exchange Cap.  The Company shall not be obligated to issue any Common Shares upon conversion of this Debenture or pursuant to Section 5(e), and no Holder shall be entitled to receive any Common Shares if the issuance of such Common Shares would exceed that number of Common Shares which the Company may issue upon the conversion of the Debentures and the Warrants without breaching the Company’s obligations under the rules and regulations of the NYSE MKT (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (i) obtains the approval of its shareholders as required by the applicable rules of the NYSE MKT and the Toronto Stock Exchange for issuances of Common Shares in excess of such amount or (ii) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Holder.  Until such approval or written opinion is obtained, no Holder shall be issued in the aggregate, upon conversion of this Debenture or pursuant to Section 5(e), Common Shares in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the original principal amount of this Debenture on the Original Issue Date and the denominator of which is the aggregate original principal amount of all of the Debentures on the Original Issue Date (the “Exchange Cap Allocation”).  In the event that the Holder shall sell or otherwise transfer any of this Debenture, the transferee shall be allocated a pro rata portion of the Holder’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee.  In the event that, at any time prior to the Maturity Date, the Company issues a number of Common Shares under this Debenture and the Warrants equal to 15% of the outstanding Common Shares on the date of the Purchase Agreement or it would otherwise reasonably be expected that the number of Common Shares issued pursuant to the  Transaction Documents would exceed the Exchange Cap, then the Company will promptly seek the approval of its shareholders as required by the applicable rules of the NYSE MKT and the Toronto Stock Exchange for issuances of Common Shares in excess of the Exchange Cap.
