2	THE LOAN

2.1	Subject to the terms of this Agreement, and in reliance upon the Warranties and undertakings of the Company contained herein, the Lender agrees to make available to the Company the Loan.

2.2	The Lender will only be obliged to advance the Loan to the Company if it has received the documents and evidence listed in clause 2.3 below in a form and substance reasonably satisfactory to the Lender.

2.3	The Lender shall not be required to advance the Loan to the Company unless the following conditions have been satisfied:

(a)

the Warranties being true and accurate, by reference to the facts and circumstances then existing; and

(b)

the execution by the Company of the Warrant Deed and the delivery by the Company to the Lender of the executed Warrant Deed and accompanying Warrant certificates.

3	Purpose

The Company shall apply the Loan to pay U$1,000,000 due to the EPA and for general working capital purposes.

4	INTEREST

4.1	The Company shall pay interest on the outstanding Loan at the rate of 10% per annum, such interest to accrue from the Advance Date up to the date of repayment or conversion in full of the Loan.

4.2	Interest on the outstanding amount of a Loan shall be calculated on a daily basis and based on a year of three hundred and sixty five (365) days.

4.3	The Company shall pay accrued and unpaid interest on the Conversion Date as provided in clause 6.1 or the Maturity Date to the extent the Lender does not exercise its conversion rights hereunder.

4.4	If the Company fails to pay any sum on the due date for payment under this Agreement or fails to allot and issue any Common Shares to the Lender in accordance with the terms hereunder, interest will accrue on a daily basis (payable on demand) on the outstanding principal amount of the Loan from the date of default until actual payment or conversion (both before and after judgement) at the rate of 20% per annum.

5	Repayment

5.1	The Loan, including accrued interest thereon, shall be repayable by the Company to a bank account notified in advance to the Lender on the date that is one (1) year from the Advance Date (the “Maturity Date”).

5.2	The Company shall not be entitled to prepay the Loan in part or in whole.

6	LENDER’S CONVERSION OPTION

6.1	Subject to this clause 6, the Lender shall have the option on any date specified by the Lender in its discretion prior to the Maturity Date (“Conversion Date”) by providing written notice to the Company (“Conversion Notice”), to require a conversion of all or part of the Loan and any accrued interest thereon into Common Shares, and the Company shall effect a conversion of such amount as is specified by the Lender in the Conversion Notice (the “Conversion Amount”) into Common Shares.

6.2	The number of Common Shares to be issued in satisfaction of the Conversion Amount (the “Conversion Shares”) shall be equal to that number resulting when the Conversion Amount is divided by the Conversion Price.

6.3	The Company acknowledges that the Lender may sell some or all of the Conversion Shares allotted and issued to it at such times and in such numbers as the Lender may decide.

6.4	Notwithstanding the other provisions set out in this clause 6, and in the event the issuance to the Lender of any Conversion Shares then required to be issued hereunder would breach the Company’s constitution, or any laws or regulations, including the CSA Trading Rules or the rules of any other stock exchange on which the Common Shares are then listed, the Company may elect to make a cash payment to the Lender in lieu of and in full satisfaction of the obligation to issue such number of Conversion Shares as would otherwise give rise to such breach, with the balance being issued in accordance with the Conversion Notice. The Company undertakes to the Lender that before making any such election it shall use its best endeavours to obtain the consents and approvals necessary to issue the relevant Conversion Shares (including obtaining any shareholder authorities and the publication of any prospectus or offer document). If such consents and approvals cannot be obtained within two months of date of the Conversion Notice, the Company may elect to make the cash payment promptly which shall be equal to the number of Conversion Shares which may not be issued, multiplied by the Conversion Price.

6.5	Notwithstanding the other provisions set out in this clause 6, if at any time during the TERM of this Agreement, in the event the issuance to the Lender of any Conversion Shares then required to be issued hereunder would, together with the number of Common Shares which could arise on exercise of all the Lender’s outstanding rights to Common Shares under the Warrant Deed, result in the Lender holding 10% or more of the Company’s issued Common Shares, the Company shall, instead of issuing any such Conversion Shares, be required to make a cash payment promptly to the Lender which shall be equal to the number of Conversion Shares which may not be issued, multiplied by the Conversion Price. The provisions of this clause shall cease to apply in circumstances where the Lender acquires any interest in Common Shares other than under the terms of this Agreement and the Warrant Deed, which, together with any Conversion Shares already issued and the number of Common Shares which could arise on exercise of all the Lender’s outstanding rights to Common Shares under the Warrant Deed, result in the Lender holding 10% or more of the Company’s issued Common Shares.

6.6	Following conversion, and for so long as the Lender holds 5% or more of the Company’s issued Common Shares, it shall have the right to appoint and remove a Director to the board of the Company.

7	REORGANISATION

7.1	If any Reorganisation takes place after the date of this Agreement, such adjustments shall be made to the Conversion Price and number of Conversion Shares as the Auditors shall certify in writing to the Company and the Lender to be necessary in order that, after such adjustment:

(a)

the total number of Conversion Shares which may be issued pursuant to the Conversion Notice, is such that Conversion Shares when issued:

	(i)	will carry as nearly as possible (and in any event not less than) the same proportion of the votes as the Conversion Shares would have carried prior to such adjustment; and

	(ii)	will carry the entitlement to participate in the same proportion in the profits and assets of the Company as would the total number of Conversion Shares converted pursuant to the Conversion Notice immediately prior to the event giving rise to such adjustment;

7.2	The Company shall procure that no such event as is referred to in clause 7.1 shall occur prior to the end of the Maturity Period unless the Auditors shall either (i) prior to or (ii) contemporaneously with, the relevant resolution of the members of the Company or the Directors giving effect to or sanctioning such event, certify the appropriate adjustments. The Company shall send notice of such adjustments to the Lender as soon as practicable (and in any event no later than seven days) following such resolution as aforesaid.

7.3	In calculating any entitlement to Conversion under this clause 7 fractions shall be rounded down to the nearest whole Common Share.

8	Taxes

8.1	All payments due to be made by the Company to the Lender under this Agreement, whether of principal, interest or otherwise, shall be made without deduction or withholding for, or on account of, any Taxes, except to the extent the Company is required by law to deduct or withhold any Taxes on any amounts payable hereunder. If at any time the Company is required to make any deduction or withholding in respect of Taxes from any payment due hereunder, then the Company shall pay any such additional amount to the Lender as is necessary to ensure that, after the making of such deduction or withholding, the Lender receives on the due date for such payment (and retains, free from any liability in respect of such deduction or withholding) a net sum equal to the sum which it would have received had no such deduction or withholding been required to be made. The Company shall use its reasonable endeavours to obtain from the applicable authority as soon as possible after making such payment (to the extent they are issued by such authority) an official receipt or other appropriate evidence issued by such authority evidencing that the payment has been duly remitted to the appropriate authority and shall furnish the Lender within ten (10) days of receipt of the same such official receipt or evidence.

8.2	Without prejudice to the provisions of clause 8.1, if the Lender is required to make any payment on account of Tax (and such Tax is directly incurred as a result of the Lender having entered into, performed its obligations under and received the benefits of this Agreement, and not being a Tax imposed on all or part of the Investor’s net income or as the result of any of the Lender’s business operations anywhere in the world) on any sum received or receivable under this Agreement by the Lender from the Company (including, without limitation, any sum received or receivable under this clause 8.2) the Company shall, upon demand of the Lender, indemnify the Lender against that payment or liability, together with any interest, penalties and reasonable expenses payable or incurred in connection therewith.
