5.3	Funding of Joint Venture Company

(a)

The Operator shall create and maintain a funding tracking account (the “Tracking Account”) for each of the Shareholders. The total initial amount to be recorded in Vista Barbados’ Tracking Account shall be $4,000,000 and the total initial amount to be recorded in Pan Asia’s Tracking Account shall be $6,000,000.

For greater certainty, the Tracking Accounts are intended to track the actual and deemed capital contributions of the Shareholders for determining each Shareholder’s Proportionate Share and is separate from the capital of Salu Siwa for Australian Corporate Law purposes [Note to draft: Aus counsel to review.]. Each Shareholder’s Tracking Account shall be credited with any further capital contributions made by such Party as set out in this Section 5.2.

(b)	Each Shareholder shall fund its Proportionate Share of all costs, expenses and liabilities incurred by Salu Siwa through subscriptions for treasury Shares (at the same par share price), which Proportionate Share, from time to time, shall be determined as follows:

“Proportionate Share” at any time (subject to adjustment for Double Dilution below) means:

(i)	the total amount of the Shareholder’s then Tracking Account, divided by:

(ii)	the total amount of the then Tracking Accounts of both Shareholders.

Each time a Shareholder funds costs, expenses and liabilities incurred by Salu Siwa, such amount shall be credited to the Shareholder’s Tracking Account. For the purposes of Australian Corporate Law, if a Shareholder contributes funds pursuant to this Section 5.2(b), the Parties shall cause to be issued to such funding Shareholder the number of additional Shares as is necessary so that the Shareholders’ respective Shareholdings in Salu Siwa reflect their then Proportionate Share.

(c)

Promptly following approval of a Program and Budget, the Operator shall prepare and provide to the Board of Directors for consideration and approval a proposed schedule of the monthly cash calls the Operator anticipates making over the course of that Program and Budget. On the basis of each approved Program and Budget, the Operator shall submit prior to the last day of each month a cash call billing to Shareholders for estimated cash requirements of Salu Siwa for the next month. Within 30 days after receipt of each billing, each Shareholder shall advance its Proportionate Share of such cash requirements. The Operator shall record all funds received by Salu Siwa pursuant to such cash advances. The Operator may issue cash calls in order to maintain a cash balance in Salu Siwa approximately equal to the reasonably expected rate of Salu Siwa’s

B-16

Exhibit 10.43

(d)

expenditures under an approved Program and Budget for a maximum of 30 days. All funds in excess of immediate cash requirements received by Salu Siwa pursuant to cash calls shall be invested by the Operator for the benefit of Salu Siwa in cash management accounts and investments selected at the discretion of the Operator, which accounts may include, but are not limited to, money market investments and money market funds.

(e)

Notwithstanding the above, within 20 days of approval of a Program and Budget by the Board of Directors, each Shareholder will have the opportunity to elect to contribute its Proportionate Share, a lesser amount or no amount to such Program and Budget. Failure of a Shareholder to provide an election to the Operator within such 20 day period shall be deemed to be an election to fund its Proportionate Share. In the event that a Shareholder notifies the Operator that it elects not to fund its Proportionate Share (whether less than its Proportionate Share or none at all) of a Program and Budget within such 20 days of the Board of Directors approving such Program and Budget, the other Shareholder will have the right, but not the obligation, to fund all or part of the unpaid portion of the advance by increasing its contribution or subscription, as the case may be, such that it results in straight-line dilution (“Straight-Line Dilution”) of the Shareholder not funding (as reflected by the Shareholders’ Tracking Accounts after such funding is credited) in accordance with the following formula:

Y% =	100 x	A1 + A2
		B1 + B2 +A2

Where:

Y	=	the non-funding Shareholder’s Proportionate Share (expressed as a percentage);
A1	=	the amount of the non-funding Shareholder’s Tracking Account immediately before the first cash call of the Program and Budget at issue;
A2	=	the non-funding Shareholder’s contribution, if any, to all cash calls for the Program and Budget at issue;
B1	=	the total of the Tracking Accounts of both Shareholders immediately before the first cash call of the Program and Budget at issue; and
B2	=	the funding Shareholder’s contribution, if any, to all cash calls for the Program and Budget at issue.

In the event a Shareholder suffers a reduction in its Proportionate Share pursuant to the above Straight-Line Dilution formula, the other Shareholder’s Proportionate Share will be correspondingly increased by the amount of the reduction.

If the other Shareholder does not wish to fund the elected shortfall, the Program and Budget may be sent back to the Board of Directors for amendment and re-approval.

(f)

In the event that a Shareholder fails to advance cash to fund a cash call billing submitted by the Operator pursuant to Section 5.2(c), in accordance with its election under Section 5.2(d), the other Shareholder will have the right, but not the obligation, to fund all or part of the unpaid portion of the advance by making a demand loan to the non

B-17

Exhibit 10.43

(g)

funding Shareholder at an annual rate of interest equal to the U.S. Prime Rate (a “Cover Payment”). Each and every Cover Payment shall constitute a demand loan bearing interest from the date of the advance at the Prime Rate. If more than one Cover Payment is made, the Cover Payments shall be aggregated and the rights and remedies described herein pertaining to an individual Cover Payment shall apply to the aggregated Cover Payments. The failure to repay such loan upon demand shall be a default. All funding will be funded as subscriptions for treasury Shares and not contributed surplus.

(h)

In the event that a Shareholder fails to advance cash to fund a cash call billing submitted by the Operator pursuant to Section 5.2(c), in accordance with its election under Section 5.2(d) and no Cover Payment is made or the non-funding Party fails to pay such Cover Payment loan upon demand pursuant to Section 5.2(e), the non-funding Shareholder shall be in default and, as liquidated damages and the exclusive remedy for such default, the funding Shareholder shall be entitled to cause the non-funding Shareholder’s Proportionate Share to be diluted (and to be so reflected in the non-funding Shareholders’ Tracking Account) at a rate which is double that of Straight-Line Dilution (“Double Dilution”) in accordance with the following formula. The amount of any Cover Payment and interest not paid upon demand shall be included as an amount advanced by the funding Shareholder (and not the non-funding Shareholder):

Y% =	100 x	A1 + A2
		B1 + 2 (B2) +A2

Where:

Y	=	the non-funding Shareholder’s Proportionate Share (expressed as a percentage);
A1	=	the amount of the non-funding Shareholder’s Tracking Account immediately before the first cash call of the Program and Budget at issue;
A2	=	the non-funding Shareholder’s contribution, if any, to all cash calls for the Program and Budget at issue;
B1	=	the total of the Tracking Accounts of both Shareholders immediately before the first cash call of the Program and Budget at issue; and
B2	=	the funding Shareholder’s contribution, if any, to all cash calls for the Program and Budget at issue.

In the event a Shareholder suffers a reduction in its Proportionate Share pursuant to the above Double Dilution formula, the other Shareholder's Proportionate Share shall be correspondingly increased by the amount of the reduction. In order that the Shareholders’ Tracking Accounts will reflect the new Proportionate Shares, the non-funding Shareholder’s Tracking Account will be credited with the amount equal to A2 above and the funding Party’s Tracking Account will be credited with the amount equal to 2 times B2 above. Double Dilution shall be effective as of the date of the default giving rise to such Double Dilution.

(i)	From time to time, in the event of either Straight-Line Dilution or Double Dilution pursuant to this Section 5.2, Salu Siwa will either: (a) issue for nominal consideration,

B-18

Exhibit 10.43

(j)

such number of Shares to a funding Shareholder as is necessary so that the Shareholders’ respective Shareholdings in Salu Siwa reflect their then Proportionate Share; or (b) accept for surrender, and the non-funding Shareholders shall surrender to Salu Siwa, such number of Shares held by the non-funding Shareholder as is necessary so that the Shareholders’ respective Shareholdings in Salu Siwa reflect their then Proportionate Share following such Straight-Line Dilution or Double Dilution.

(k)	For greater certainty, in the event of either Straight-Line Dilution or Double Dilution the non-funding Party’s dilution extinguishes any debt associated with their failure to fund.

5.4	Conversion to Net Smelter Royalty

– If at any time, a Shareholder’s Proportionate Share is less than 10 percent, that Shareholder shall forthwith surrender, free and clear of all liens and encumbrances, all of its Shares for cancellation and such Shareholder shall have no further rights, interests or obligations in respect of Salu Siwa, its assets or the Property, except that as a refund Salu Siwa shall promptly enter into an agreement with such Shareholder pursuant to which such Shareholder shall receive, at the election of the receiving Shareholder, (i) a 10% carried interest in the Property, or (ii) within 60 days of the end of each calendar quarter during which the commercial production of Minerals occurs from a Property, a cash payment equal to 1.5% of Net Smelter Returns in accordance with Exhibit B.

Upon a Shareholder surrendering its Shares pursuant to this Section 5.3, such Shareholder shall cause its Representatives to the Board of Directors to immediately resign.

5.5	Return of Contributions

– No Shareholder shall be entitled to the return of any part of its capital contributions from Salu Siwa or to be paid interest in respect of such capital contributions, except as determined by the Board of Directors. No unrepaid capital contribution shall constitute a liability of Salu Siwa, PT Masmindo, the Operator or any Shareholder. A Shareholder is not required to contribute or to lend cash or property to Salu Siwa to enable Salu Siwa to return any Shareholder’s capital contributions. The provisions of this Section 5.4 shall not limit a Shareholder’s rights or obligations under Article XVIII.

5.6	Bankruptcy of a Shareholder

– A Shareholder shall cease to have any power as a Shareholder or Operator or to exercise any voting rights under its Shares or rights of approval hereunder upon the bankruptcy, insolvency, dissolution or assignment for the benefit of creditors of such Shareholder, provided that such Shareholder shall continue to be liable for all obligations of the Shareholder under this Agreement. The foregoing shall continue to apply to any of the Shareholder’s successors as a result of such bankruptcy, insolvency, dissolution or assignment for the benefit of creditors. In such event, the Shareholder shall cause its Representatives on the Board of Directors to immediately resign or be removed and such Shareholder (and any successor holding such Shareholder’s Shares) shall cease to have a right to vote on the Board of Directors and to nominate any director to the Board.

5.7	Continuing Obligations and Liabilities of Shareholders

– On dissolution of Salu Siwa under Article XVIII of this Agreement, each Shareholder shall remain liable for its respective Proportionate Share of liabilities to third parties (whether such arises before or after such dissolution), including Environmental Liabilities and Continuing Obligations, for which Shareholders or former Shareholders are determined to be personally liable under Australian Corporate

B-19

Exhibit 10.43

Law or any other applicable law. Further, and notwithstanding anything to the contrary herein, any withdrawal or deemed withdrawal of a Shareholder pursuant to Article XVIII or Section 5.3, any Transfer by such Shareholder of all or any portion of its Shares, or any reduction of a Shareholder’s Proportionate Share shall not relieve such Shareholder of its share of any such liability accruing before such resignation, Transfer or reduction. In the event of the withdrawal or deemed withdrawal of a Shareholder pursuant to Article XVIII of this Agreement, the resigning Shareholder’s share of such liabilities shall be equal to its Proportionate Share at the time such liability was incurred, after first taking into account any reduction, readjustment, and restoration under Section 5.2 and 5.3 (or, as to liabilities arising prior to the Effective Date, its initial Proportionate Share).

5.8	Indemnity by Shareholders for Salu Siwa Liabilities

– To the extent either or both Shareholders (in their capacity as shareholders) are finally determined to be personally liable for any third party losses, claims, damages and liabilities arising out of or relating to: (i) Salu Siwa, PT Masmindo or the Operations, including without limitation Environmental Liabilities and Continuing Obligations, incurred by such other Shareholder; or (ii) any Property assigned to the other Shareholder as an objecting Shareholder pursuant to Section 15.1, but only to the extent in the case of this Section 5.7 arising out of or relating to Operations, including without limitation Environmental Liabilities and Continuing Obligations, conducted prior to the date of such assignment, such Shareholder(s) shall first seek indemnity from Salu Siwa pursuant to Section 4.9(b) and only to the extent Salu Siwa does not have assets sufficient to cover such indemnity or is otherwise unable to meet its obligations thereunder, each Shareholder shall be liable to the other Shareholder to reimburse and pay to such other Shareholder its respective share of the third party losses, claims, damages and liabilities, such respective share to be based on each Shareholder’s Proportionate Share. The reimbursement obligation of a Shareholder under this Section 5.7 shall apply whether or not any such losses, claims, damages or liabilities accrue before or after the withdrawal or deemed withdrawal of such Shareholder, the Transfer by such Shareholder of all or any portion of its Shares, the dissolution or liquidation of Salu Siwa or PT Masmindo, or any reduction of such Shareholder’s Proportionate Share, but shall not apply to the extent the Shareholder is indemnified by Salu Siwa pursuant to Section 4.9(b), or to the extent such losses, claims, damages and liabilities arise out of conduct of the Shareholder requesting reimbursement described in any of clauses (i) through (iii) of Section 4.9(b). For purposes of this Section 5.7, each Shareholder’s share of such liability shall be equal to its Proportionate Share at the time such liability was incurred, after first taking into account any reduction, readjustment, and restoration under Section 5.2 and 5.3 (or, as to liabilities arising prior to the Effective Date, its initial Proportionate Share). Notwithstanding the foregoing, the provisions of this Section 5.7 shall not be construed as a waiver or reduction of the limitations of liability under Australian Corporate Law or other applicable law of the liability of a Shareholder or the Operator for Salu Siwa’s obligations.

(c)	notice that the Shareholder rejects the proposed Program and Budget.

If a Shareholder fails to give any of the foregoing responses within the allotted time, the failure shall be deemed to be an approval by the Shareholder of the Operator’s proposed Program and Budget. If a Shareholder makes a timely submission to the Board of Directors pursuant to Section [8.4(b) or (c)], then the Board of Directors shall seek to develop a Program and Budget acceptable to the Shareholders.

ARTICLE IX

AUDITS

9.1

Audits

– Upon request made by any Shareholder within 24 months following the end of any calendar year (or, if the Board of Directors has adopted an accounting period other than the calendar year, within 24 months after the end of such period), the Operator shall order an audit of the accounting and financial records of Salu Siwa and PT Masmindo for such calendar year (or other accounting period). All written exceptions to and claims upon the Operator for discrepancies disclosed by such audit shall be made not more than three months after receipt of the audit report. Failure to make any such exception or claim within the three month period shall mean the audit is correct and binding upon the Shareholders, Salu Siwa and PT Masmindo. The audits shall be conducted by a firm of certified public accountants selected by the Operator, unless otherwise agreed by the Board of Directors.

The Operator shall, at a Shareholder’s reasonable request and at the requesting Shareholder’s own expense, grant access during regular business hours to Salu Siwa’s and PT Masmindo’s books and records to satisfy the requesting Shareholder’s own audit, reporting and regulatory requirements.

ARTICLE X

RESTRICTIONS

10.1	Area of Interest

– If any Shareholder or any of its Affiliates (the “Acquiring Shareholder”) stakes, leases or otherwise acquires or becomes entitled to acquire any interest, directly or indirectly, alone or in concert with any other Person, in any mineral right, surface right, water right or other mining related assets within the Area of Interest (the “Acquired Property”), the following shall apply:

(a)

the Acquiring Shareholder shall promptly give the other Shareholder written notice thereof (including with its notice all information and data in its possession or control regarding the Acquired Property and a statement of its acquisition costs for the Acquired Property) (the “Acquisition Notice”) and unconditionally offer to transfer and assign the Acquired Property to Salu Siwa or PT Masmindo, free and clear of all liens and

B-28

Exhibit 10.43

(b)

encumbrances (other than those arising under the terms of the mineral rights or by law). The other Shareholder may elect, by notice delivered within 30 days, to require the Acquiring Shareholder to assign and transfer all of its interest in the Acquired Property to Salu Siwa in consideration for a reimbursement of the Acquiring Shareholder’s acquisition costs by Salu Siwa (other than any land transfer or other real property taxes, fees or charges paid by the Acquiring Shareholder on the original acquisition that Salu Siwa will be required to pay on the acquisition from the Acquiring Shareholder). If the other Shareholder does not elect to deliver such a notice, the Acquiring Shareholder shall be entitled to retain its interest in the Acquired Property;

(c)

if the consideration paid by the Acquiring Shareholder was other than cash or a work commitment in respect of the Acquired Property, the Acquisition Notice shall specify the cash equivalent of such consideration. The non-acquiring Shareholder may, within ten days of its receipt of the Acquisition Notice, if no mutual agreement between the Shareholders can be reached, require the determination of the cash equivalent of the consideration to be submitted to the dispute resolution process in Section 19.9, in which event the 30 day period specified in this Section 10.1 shall commence to run on the date of the binding resolution under such process. The cash value so determined and communicated in writing to the Shareholders shall be deemed to be the cash equivalent of the consideration;

(d)	if the Acquired Property to be assigned to Salu Siwa or PT Masmindo hereunder is subject to an agreement with a third party which provides for the operation (including by earn-in) of such Acquired Property then the Acquiring Shareholder shall use its reasonable best efforts to:

(i)	have Salu Siwa or PT Masmindo, as the case may be, assigned or novated into such operating agreement as to its interest; and

(ii)	if the Operator under this Agreement is not the operator pursuant to such operating agreement, to have the Operator appointed as operator pursuant to such Agreement.

Until such time as Salu Siwa or PT Masmindo, as the case may be, is assigned or novated into such an existing operating agreement, the Acquiring Shareholder shall hold Salu Siwa’s or PT Masmindo’s interest, as the case may be, in such Acquired Property in trust for Salu Siwa. During the period that such interest is held in trust, the Acquiring Shareholder shall promptly provide to the Operator any and all notices which the Acquiring Shareholder receives and the Operator, on behalf of Salu Siwa or PT Masmindo, as the case may be, shall have one-half of the time period set forth in the applicable operating agreement to advise the Acquiring Shareholder whether or not it elects to participate in the operations set forth in any such notice. Failure to respond within the time period will be deemed to be an election not to join in the proposed operation; and

(e)	each Shareholder shall cause any of its Affiliates which acquire or become entitled to acquire an Acquired Property to comply with this Section 10.1.

10.2	Right to Acquire Shares

B-29

Exhibit 10.43

10.3

If Vista Barbados does not accept the offer contained in the Offer Notice within 15 Business Days, Vista Barbados shall have the right to purchase all of Pan Asia’s interests in Salu Siwa and PT Masmindo (including, for greater certainty, all Shares then owned by Pan Asia) on the same terms as contained in the Offer Notice. An acquisition by Pan Asia pursuant to an Offer Notice will have to be completed within 30 days of the date of the Offer Notice.

Any distribution by Salu Siwa of proceeds from a Mine between the Shareholders (whether by return of capital or contributed surplus, dividend or such other method as the Shareholders may agree to) will be made at the same time and in amounts in accordance with each Shareholder’s respective Proportionate Share.

ARTICLE XIII

13.2

General

– The Parties agree that each Party shall be responsible for the tax payments, rights and other tax issues that legally correspond to each Party, in accordance with the applicable Indonesian tax legislation, Australian Tax legislation, [the ● Treaty and any applicable laws].

– All required payments of production royalties, taxes based on production of Products, and other payments out of production to private parties and governmental entities, shall be determined and made by PT Masmindo or Salu Siwa, as the case may be, in a timely manner and otherwise in accordance with applicable laws and agreements. The Operator shall furnish to the Shareholders evidence of timely payment for all such required payments. In the event PT Masmindo or Salu Siwa, as the case may be, fails to make any such required payment, any Shareholder shall have the right to make such payment and shall thereby become subrogated to the rights of such third party; provided, however, that the making of any such payment on behalf of PT Masmindo or Salu Siwa shall not constitute acceptance by the paying Shareholder of any liability to such third party for the underlying obligation.

ARTICLE XIV

ABANDONMENT AND SURRENDER OF PROPERTIES

14.1	Surrender or Abandonment of Property

– The Board of Directors may authorize the Operator to surrender or abandon part or all of the Properties. If the Board of Directors authorizes any such surrender or abandonment over the written objection of a Shareholder, PT Masmindo shall assign to the objecting Shareholder or an Affiliate designated by the Shareholder, by appropriate legal documentation and without cost to the surrendering Shareholder, all of PT Masmindo’s interest in the part of the Property to be abandoned or surrendered, and the abandoned or surrendered part of the Property shall cease to be part of the Property for purposes of this Agreement and neither PT Masmindo nor Salu Siwa shall have a further right, title or interest therein.

15.2	Exceptions

– The consent required by Section 16.1 shall not apply to a disclosure:

(a)	to a consultant, contractor, subcontractor, officer, director or employee of Salu Siwa, PT Masmindo, the Operator or any Shareholder or any of their respective Affiliates that has a bona fide need to be informed;

B-31

Exhibit 10.43

(b)	to any third party to whom the disclosing Shareholder contemplates a Transfer of all or any part of its Shares;

(c)	to any actual or potential lender, underwriter or investors for the sole purpose of evaluating whether to make a loan to or investment in the disclosing Shareholder or Salu Siwa; or

(d)	to a governmental agency or to the public which the disclosing Shareholder or Operator believes in good faith is required by pertinent law or regulation or the rules of any stock exchange on which its (or its Affiliate’s) securities are listed.

In any case to which this Section 16.2 is applicable, the disclosing Shareholder or Operator shall give notice to the other Shareholder concurrently with the making of such disclosure. As to any disclosure pursuant to Section 16.2(a), (b) or (c) [Note to draft: confirm.], only such Confidential Information as such third party shall have a legitimate business need to know shall be disclosed and such third party shall first agree in writing to protect the Confidential Information from further disclosure to the same extent as the Shareholders are obligated under this Article XVI, and the disclosing Shareholder or Operator shall be responsible and liable for any use or disclosure of the Confidential Information by such parties in violation of this Agreement and such other writing.

Such approval shall not be unreasonably withheld or delayed. Failure of a Shareholder to comment within three Business Days of receipt of a draft press release or disclosure document will be deemed to constitute approval. However, such approval shall not be considered certification by the other Shareholder of the accuracy of the information in such press release or public disclosure, or a confirmation by it that the content of such press release or public disclosure complies with the rules, policies, by-laws and disclosure standards of the applicable regulatory authorities or stock exchange.

ARTICLE XVI

If within a 60 day period both Shareholders elect to withdraw, then the Joint Venture shall instead be deemed to have been terminated by the written agreement of the Shareholders pursuant to Section 18.1 and the Parties shall proceed to take all necessary action to dissolve (i) Salu Siwa in accordance with Australian Corporate Law and any other applicable law; and (ii) PT Masmindo in accordance with Indonesian Corporate Law and any other applicable law.

INITIAL PROGRAM AND BUDGET

Pan Asia proposes an initial budget of US$1,350,000 for the first 12 months of the option period. Central to the work program is the commencement of an ▇▇▇▇▇ or Environmental Impact Statement by suitably qualified contractors. In addition the database will be modelled in light of current changes in the metals price and some resource drilling is planned principally concentrating on the further definition of vertical structures within the Awak Mas deposit due to their generally higher grade.

Some initial optimisation studies will be undertaken to gain some insight into the best mining scenario for the deposit for completion of the Feasibility Study in year 2.

Rehabilitation of the camp and core shed to bring the storage of drill core in aluminum trays is planned.

Detailed studies on two critical elements in the feasibility will be undertaken - costs to bring the road up to a standard for heavy equipment transport and alternatives to capital costs of a Power plant for the mine.

Details of the budget are provided below including G&A costs.

Pan Asia proposes an initial budget of US$1,350,000 for the first 12 months of the option period. Central to the work program is the commencement of an ▇▇▇▇▇ or Environmental Impact Statement by suitably qualified contractors and public meetings to be held by PT Masmindo and its representatives in accordance with prevailing Indonesian regulations.

The geological database will be modelled in light of current changes in the metals price and potential mining scenarios of the deposit. Some resource drilling is planned principally concentrating on the further definition of vertical structures within the Awak Mas deposit due to their generally higher grade. A suitably-qualified project manager will be hired.

A scoping study and initial optimisation studies will be undertaken by recognized international consultants to gain some insight into the best mining scenario for the deposit for completion of the Feasibility Study in year two and to provide necessary technical information for the ▇▇▇▇▇.

Rehabilitation of the camp and facilities is planned due to planned increase in use throughout 2010.
