      is the Manager, and the third, who will be chairman, to be appointed by
      the first two arbitrators or as hereinafter provided. If any of the
      parties to the dispute fails to appoint an arbitrator within thirty (30)
      days after receiving notification of a referral to arbitration by another
      party, then such arbitrator will be appointed by the President of the
      international Chamber of Commerce.

      Furthermore, if the two arbitrators so appointed do not appoint a third
      arbitrator within thirty (30) days from the appointment of the second
      arbitrator such third arbitrator will also be appointed by the President
      of the International Chamber of Commerce. After the appointment of the
      third arbitrator, the Board will convene at a place selected by him and
      proceed with the arbitration hearing without delay. After such hearing,

      determine. The Board will determine by majority vote the rules of evidence
      and procedure that will apply to the hearing before the Board, provided
      that each Joint Venturer and the Manager will be entitled to submit oral
      evidence to the hearing. The Manager and the Joint Venturers will be bound
      by the majority decision of the Board, whose decision shall be final.

(f)   In the event that Placer's Percentage Interest in the Joint Venture is
      reduced to less than 20% and a majority in Percentage Interest of the
      other Joint Venturers jointly notify the Manager in writing that they do
      not wish the Manager to continue as Manager as of a specified date, the
      position of Manager shall become vacant on the date specified in the said
      notice.

Clause 10. Termination by Manager

                                 OPERATING PHASE
                    OPERATING FEE AND BASIS FOR REIMBURSEMENT

1.    INTERPRETATION

In this Schedule the following terms shall have the meanings set out below:

"Operating Fee" means the fee payable to the Manager as provided in Paragraph 5
hereof.

"Operating Year" means each period of twelve (12) consecutive calendar months
commencing from the commencement of the Operating Phase.

"Consumer Price Index" or "CPI" shall mean the Consumer Price Index for all
consumers published by the Bureau of Labor Statistics of the United States
Department of Labor in its monthly "Consumer Price Index Detailed Report," as it
is calculated from time to time. In this definition, reference to the Consumer
Price Index includes the same index but with a different name, and the same
index adjusted mathematically to take account of a change in an Operating Year
(provided that indices based on the same year are used throughout the
calculation), and the reference to the United States Bureau of Labor Statistics
includes a reference to that Bureau but with a different name, and any
governmental agency in the United States having similar functions. If the
Consumer Price Index is not published for any reason for any month, the Joint
Venturers shall endeavor to agree on a substitute index. If they fail to
unanimously agree within 14 business days commencing from the time a calculation
is to be made, any Joint Venturer may request the President for the time being
of the Institute of Chartered Accountants in Australia to nominate within 5 days
of being so requested an expert to determine a substitute index within 30 days
of being so nominated. The expert shall act as an expert and not as an
arbitrator and his decision shall be final and binding on the Joint Venturers.
The costs of the determination shall be borne by the Joint Venturers in
accordance with the Percentage Interest.

2.    REIMBURSEMENT OF MANAGER

pursuant to this Agreement or the Joint Venture Agreement during the Operating

Venturers to substantiate any costs or expenses pursuant to paragraph 2 hereof.

On, or as soon after as practical, the 1st day of each calendar month
immediately following a calendar month in which services have been performed;

(a)   the Manager shall prepare and submit to each Joint Venturer a detailed
      invoice showing that Joint Venturer's proportion, in accordance with its
      Percentage Interest, of:

      (i)   actual salary and on-costs of employees of the Manager calculated in
            accordance with sub paragraph 2(a) of this Schedule C;

      (ii)  all other costs and expenses referred to in paragraph 2 of this

<PAGE>

      to be due, (if any) in Kina or in such other currency as the Manager may

(c)   (i)   Any Joint Venturer shall have the right to dispute any such invoice
            by notice as hereunder provided not later than 180 days after the

            received. If a Joint Venturer does not dispute any invoices within
            the aforesaid time, then such invoice shall be deemed to be
            undisputed and final.

      (ii)  If a Joint Venturer disputes any invoices as aforesaid:

            (1)   the Joint Venturer shall give notice in writing to the Manager
                  detailing the dispute and shall pay any unpaid and undisputed
                  portion of the invoice forthwith; and

            (2)   the dispute shall be submitted to the auditors of the Joint
                  Venture acting as experts and not as arbitrators, to determine
                  the amount, if any, payable by the Joint Venturer. In order to
                  resolve the dispute the auditors shall, as may be necessary,
                  have access to the books and records of the Manager and may at
                  their discretion seek independent assistance or advice. The
                  Joint Venturer shall pay any balance that the auditors
                  determine as due to the Manager within 7 days of the auditors
                  notifying the Joint Venturer of such determination. If the

                  further pay interest on the said amount at the rate set out in
                  Clause 5(b) of the Joint Venture Agreement. The auditors costs
                  of such determination shall be borne by the Manager if the
                  balance (if any) certified by the auditors as due is less than
                  the disputed portion of the invoice and by the Joint Venturer
                  if the invoice is certified as correct.
