5.1 Each of the following events will constitute an “Event of Default” hereunder:

Borrower fails to make any payment when due under this Note on the applicable due date;

After receiving a Notice of Conversion in accordance with the terms herein, and notwithstanding said terms of this Note and without written waiver of said terms from the Holder, Borrower fails to issue the Common Shares to Holder pursuant to Section 6 hereof;

A receiver is appointed for any material part of Borrower’s property, Borrower makes a general assignment for the benefit of creditors, or Borrower becomes a debtor or alleged debtor in a case under an applicable Bankruptcy Code or becomes the subject of any other bankruptcy or similar proceeding for the general adjustment of its debts or for its liquidation;

5.2 Upon the occurrence of any Event of Default, all accrued but unpaid expenses, accrued but unpaid interest, all principal and any other amounts outstanding under this Note will (i) in the case of any Event of Default under Section 5(c), become immediately due and payable in full without further notice or demand by the Holder and (ii) in the case of any Event of Default other than under Section 5(c), become immediately due and payable upon written notice by or on behalf of the affected Holder to Borrower. Notwithstanding any other provision of this Note, the Holder agrees that the Holder will only exercise Holder’s rights and remedies under this Note and will not take any action, including commencement or prosecution of litigation or any other proceeding to collect this Note, until such time as the Borrower has had the opportunity to cure any Event of Default as described herein within thirty (30) days of said notice of default, or otherwise agreed to resolve any said Event of Default in a manner and within a time so agreed to and set down in writing by the parties hereto.

5.3 Any amount that has not been paid in accordance with eh terms of this Note, will bear interest at the rate of the lesser of (i) twenty percent (20%) per annum or (ii) the maximum amount permitted under Canadian Law from the due date thereof until the same is paid in full.

5.4 Without in any way limiting the Holder’s right to pursue other remedies, including actual damages and/or equitable relief, the parties agree that if the Holder elects to convert the Note, as allowed pursuant to Section 6 herein, and delivery of the Common Shares issuable upon conversion of this Note is not delivered by the deadline in Section 6 herein, the Borrower shall pay to the Holder USD $1,000 per day in cash, for each day beyond the deadline that the Borrower fails to deliver such Common Shares. Such cash amounts shall be paid to Holder by the fifth day of the month following the month in which it has accrued or, at the option of the Holder (by written notice to the Borrower by the first day of the month following the month in which it has accrued), shall be added to the principal amount of this Note, in which interest shall accrue thereon in accordance with the terms of this Note. The Borrower agrees that the right to receive Common Shares is a valuable right to the Holder. The damages resulting from a failure, attempt to frustrate, interference with such conversion right are difficult if not impossible to qualify. Accordingly, the parties acknowledge that the liquidated damages provision contained in this Section 5 are justified.

6.	Conversion.

6.1 Upon the Maturity Date, the Holder will have the right, at its option, to convert all the Principal Amount hereof into Common Shares of the Company in a manner and in accordance with Section 6.2 below at the conversion price as set forth below in 6.3 below (subject to adjustment as described herein).

6.2 In the event that the Holder elects to convert the Principal Amount of this Note into Common Shares, the Holder will give the Notice of Conversion to the Borrower before 4:00 p.m. (EST) on the Maturity Date. No later than fifteen (15) business days from the receipt of the then delivered Notice of Conversion to the Borrower, the Borrower will deliver to the Holder the agreed upon Common Shares equal to 3.23% of the fully diluted share capital of the Borrower as of the Conversion Date. The Borrower will cooperate with any reasonable requests made by the Holder to substantiate the capitalization, including the execution of additional documents containing legal representations. The Holder must surrender this Note to the Borrower upon receipt of the Common Shares. Pursuant to the terms of the Notice of Conversion, the Borrower will issue instructions to its transfer agent as soon as practicable thereafter, to cause to be issued and delivered to the Holder certificates for the number of Common Shares to which such Holder will be entitled. The Borrower will not issue fractional Common Shares upon conversion, but the number of Common Shares to be received by the Holder upon conversion will be rounded up the next whole number. In the case of the exercise of the conversion rights set forth herein the conversion privilege will be deemed to have been exercised and the Common Shares issuable upon such conversion will be deemed to have been issued upon the date of receipt by the Borrower of the Notice of Conversion.

6.3 If the Holder elects to convert the Principal Amount under the Note to Common Shares, the Principal Amount will be convertible into shares of Common Shares equal to 3. 23% of the fully diluted share capital of the Borrower as of the Conversion Date.

6.4 The Borrower will reserve for issuance and maintain available, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the full conversion of the Principal Amount under the Note, the full number of Common Shares deliverable upon the conversion of the Note. The Borrower will from time to time (subject to obtaining necessary director and shareholder approvals), in accordance with applicable laws and its governing documents, increase the number of shares of its Common Shares authorized if at any time the authorized number of shares of its Common Shares remaining unissued shall not be sufficient to permit the full conversion of the Principal Amount under the Note.

6.5 Termination of Rights. All rights with respect to this Note will terminate upon the effective conversion of the entire Balance of the Note as provided in Section 6 hereof. In any event, the Holder will not be entitled to receive any stock certificates representing the shares of Common Shares issuable upon conversion of this Note unless and until Holder has surrendered the original of this Note (or Lost Note Documentation where applicable).

CERTIFICATES; NO FRACTIONAL SHARES; LIMITATION ON MERGER, SALE OR CONSOLIDATION; AND SUBSEQUENT DEBT ISSUANCES OR EQUITY SALES.

7.1 Subject to Section 6 hereof, as soon as practicable after conversion of this Note pursuant to Section 6 hereof Borrower at its expense will register Common Shares in Borrower’s Register of Shareholders in the name of the respective Holder and will cause to be issued in the name of Holder and to be delivered to Holder, a certificate or certificates for the number of Common Shares to which Holder shall be entitled upon such conversion (bearing such legends as may be required by applicable provincial, state and/or federal securities laws in the opinion of legal counsel of Borrower, by Borrower’s Articles of Incorporation and Bylaws and by any agreement between Borrower and Holder), together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note. No fractional shares will be issued upon conversion of this Note. If upon any conversion of this Note (and after aggregating the amounts of all other Notes held by the same Holder which are converted at the same time as this Note), a fraction of a share would otherwise be issued, then in lieu of such fractional share, Borrower will round up to the nearest whole share.

7.2 Except as contemplated by any proposed business combination between the Borrower and the Holder, the Borrower may not, directly or indirectly, consolidate with or merge into another person or sell, lease, conveyor transfer all or substantially all of its assets (computed on a consolidated basis), whether in a single transaction or a series of related transactions, to another person or group of affiliated persons, without the written permission of the Holder.

7.3 From the date hereof until such time as the Note is no longer outstanding, the Borrower will not, without written consent of the Holder, which consent will not be unreasonably withheld by the Holder, issue any convertible debt or issue any derivative securities.

8.	PROVISIONS RELATING TO SHAREHOLDERS RIGHTS.

8.1 No Voting or Other Rights. This Note does not entitle the Holder to any voting rights or other rights as a shareholder of Borrower, unless and until (and only to the extent that) this Note is actually converted into shares of Borrower’s capital stock in accordance with its terms. In the absence of conversion of this Note into Common Shares, no provisions of this Note, and no enumeration herein of the rights or privileges of the Holder, will cause the Holder to be a shareholder of Borrower for any purpose.

9.10 Capitalization. No person has any right of first refusal, pre-emptive right, right of participation, or any similar right to participate in the transactions contemplated by the Note.

REPRESENTATIONS, WARRANTIES AND CERTAIN AGREEMENTS OF HOLDER. Holder hereby represents and warrants to and agrees with Borrower as follows.

10.1 Authorization. This Note constitutes Holder’s valid and legally binding obligations, enforceable against Holder in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and (ii) the effect of rules of law governing the availability of equitable remedies. Holder represents and warrants to Borrower that Holder has full power and authority to enter into this Note.

10.2 Purchase for Own Account. This Note, the Common Shares are being and may be acquired for investment for Holder’s own account, not as a nominee or agent, and not with a view to the public resale or distribution thereof within the meaning of the Act, and Holder has no present intention of selling, granting any participation in, or otherwise distributing the same. For clarity, this representation is that the Borrower is not selling, nor may it be deemed to have sold securities to an underwriter as defined in applicable Securities Act.

10.3 No Solicitation. At no time was Holder presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Securities.

10.4 Disclosure of Information. Holder has received or has had full access to all the information Holder considers necessary or appropriate to make an informed investment decision with respect to the Securities. Holder further has had an opportunity to ask questions and receive answers from Borrower regarding the terms and conditions of the offering of the Securities and to obtain additional information (to the extent Borrower possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder had access. The foregoing, however, does not in any way limit or modify the representations and warranties made by Borrower in Section 9 hereof.

10.5 Investment Experience. Holder understands that the purchase of the Securities involves substantial risk. Holder (i) has experience as a Holder in securities of companies in the development stage and acknowledges that Holder is able to fend for itself, can bear the economic risk of Holder’s investment in the Securities and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of this investment in the Securities and protecting Holder’s own interests in connection with this investment in the Securities or (ii) has a pre-existing personal or business relationship with Borrower and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. Holder acknowledges that any investment in the Securities involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

10.6 Restricted Securities. Holder understands that the Securities are characterized as “restricted securities” since they are being acquired from Borrower in a transaction not involving a public offering, and that under such applicable Act and applicable regulations the Securities may be resold only in certain limited circumstances. Holder further understands that Borrower is under no obligation to register the Securities, and Borrower has no present plans to do so. Furthermore, Holder is familiar with the relevant securities laws and regulations applicable to this Note, as presently in effect, and understands the limitations imposed thereby and by such legislation on resale of the Securities. Holder understands that no public market now exists for any of the Securities and that it is uncertain whether a public market will ever exist for the Securities.

10.7 Further Limitations on Disposition. Without in any way limiting the representations set forth above, Holder further agrees not to make any disposition of all or any portion of the Securities unless and until:

there is then in effect a registration statement under an applicable securities Act or regulation covering such proposed disposition and such disposition is made in accordance with such effective registration statement; or

(i) Holder will have notified Borrower in writing of the proposed disposition and will have furnished Borrower with a detailed statement of the circumstances surrounding the proposed disposition, and (ii) if reasonably requested by Borrower, Holder will have furnished Borrower with an opinion of counsel, reasonably satisfactory to Borrower that such disposition will not require registration of such shares under any applicable securities legislation.

10.8 Information on Company. The Holder has received in writing from the Borrower such information concerning the Borrower’s operations, financial condition and other matters as the Holder has requested, identified thereon as OTHER WRITTEN INFORMATION (such other information is collectively, the “Other Written Information”), and considered all factors the Holder deems material in deciding on the advisability of investing the Principal Amount.

The Holder is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations under this Note in accordance with the terms hereof, provided that for purposes of the representation made in this sentence, the Holder is assuming and relying upon the accuracy of the relevant representations and agreements of the Borrower herein.

11.3 Transfer. Neither this Note nor any of the rights or obligations of Holder hereunder may be assigned, conveyed or transferred, in whole or in part, without Borrower’s prior written consent, which Borrower may withhold in its sole discretion; provided, however, that this Note may be assigned, conveyed or transferred without the prior written consent of Borrower to any Affiliate of Holder who: (a) executes and delivers an acknowledgement that such transferee agrees to be subject to, and bound by, all the terms and conditions of this Note, (b) makes the representations and warranties to Borrower that are set forth in Section 10 hereof and (c) (if requested by Borrower) delivers to Borrower an opinion of legal counsel, reasonably satisfactory to Borrower, that such transfer complies with state and federal securities laws.

Subject to the foregoing, the rights and obligations of Borrower and Holder under this Note and the other Financing Documents will be binding upon and benefit their respective permitted successors, assigns, heirs, administrators and transferees.

11.4 Maximum Interest. In the event that any provision of this Note would oblige the Borrower to make any payment of interest (more so than the maximum interest of 10% per annum agreed to herein) or any other payment which is construed by a court of competent jurisdiction to be interest in an amount or calculated at a rate which would be prohibited by Applicable Law (as defined below) or would result in a receipt by the Holder of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)), then notwithstanding such provision, such amount or rate will be deemed to have been adjusted nunc pro tunc to the maximum amount or rate of interest (which for clarity herein is agreed to be calculated at 10% per annum), as the case may be, as would not be so prohibited by Applicable Law or so result in a receipt by the Lender of interest at a criminal rate, and the following shall apply: (i) the provisions of this paragraph shall govern and control, (ii) neither the Borrower nor any other person or entity now or hereafter liable for the payment thereof, will be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by such Applicable Law, (iii) any such excess which may have been collected will be either applied as a credit against the then unpaid principal amount thereof or refunded to the Borrower at the Holder’s option, and (iv) the effective rate of interest will be automatically reduced to the maximum lawful rate of interest allowed under the Applicable Law as now or hereafter construed by the courts having jurisdiction thereof. It is further agreed that without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under the Note which are made for the purpose of determining whether such rate exceeds the maximum lawful rate of interest, will be made, to the extent permitted by Applicable Law, by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the Note evidenced thereby, all interest at any time contracted for, charged or received from the Company or otherwise by the Holder in connection with this Note.

11.5 Independent Legal Advice to the Holder. The Borrower invites and encourages the Holder to seek independent legal advice with respect to the terms of the Note. The Holder hereby acknowledges and agrees that the Holder has had the opportunity to seek, and were not prevented from seeking, independent legal advice prior to the execution and delivery of the Note. If the Holder does not avail itself of that opportunity to receive independent legal advice prior to signing the Note, the Holder has done so voluntarily without any pressure or influence by the Borrower, and covenants that the right to do so has been specifically waived, and agrees that the Holder’s failure to obtain independent legal advice may not be used to challenge the enforceability of the Note.
