AGREEMENT BETWEEN

THE GOVERNMENT OF THE DEMOCRATIC REPUBLIC OF TIMOR-LESTE AND THE GOVERNMENT OF AUSTRALIA RELATING TO THE UNITISATION OF THE SUNRISE AND TROUBADOUR FIELDS

The Government of the Democratic Republic of Timor-Leste and the Government of Australia,

Considering that the exploration in the Timor Sea between Timor-Leste and Australia has proved the existence of petroleum deposits which extend across the eastern boundary of the Joint Petroleum Development Area; those deposits being known as the Sunrise and Troubadour deposits (collectively known as Greater Sunrise);

Noting that Timor-Leste and Australia have, at the date of this agreement, made maritime claims, and not yet delimited their maritime boundaries, including in an area of the Timor Sea where Greater Sunrise lies;

Desiring, before production commences, to make provisions for the integrated exploitation of Greater Sunrise;

Acknowledging that Timor-Leste and Australia agreed under Annex E of the Timor Sea Treaty to unitise Greater Sunrise on the basis that 20.1% of Greater Sunrise lies within the JPDA and that production from Greater Sunrise shall be distributed on the basis that 20.1% is attributed to the JPDA and 79.9% is attributed to Australia;

Recalling further the Memorandum of Understanding between the Government of the Democratic Republic of Timor-Leste and the Government of Australia of 20 May 2002 in which they agreed to work expeditiously and in good faith to conclude a unitisation agreement for Greater Sunrise;

Have agreed as follows:

ANNEX III

Petroleum Valuation Principles

1. This Annex sets out the principles to be applied in determining the value of petroleum in non- arm’s length transactions under Article 16, for the purposes of cost recovery and production sharing of that part of Unit Petroleum apportioned to the Joint Petroleum Development Area in accordance with the Apportionment Ratio.

1. An arm’s length transaction is one where the parties to the transaction are dealing at arm’s length with each other in relation to the transaction. Whether the parties are dealing at arm’s length is determined not only by the relationship between the parties but also by the nature of the dealings between those parties, even if they are otherwise independent of each other.

1. In determining whether an arm’s length transaction has taken place, the Regulatory Authorities shall, amongst other things, have due regard to the functions performed, assets used and risks assumed. In assessing the allocation of risk, and the associated return to those risks, regard shall be had to the outcomes expected of parties acting at arm’s length.

1. Where there is no arm’s length sale, the petroleum shall be valued with reference to a comparable uncontrolled price (CUP) at the Valuation Point.

1. If no CUP exists petroleum shall be valued by the application of the pricing methodology set out in paragraph 6.  In this methodology:

Calculation Period means the period beginning with the year five years before production of petroleum from Greater Sunrise is scheduled under the Development Plan to commence

(t = 0), and ending with the year when production is scheduled under the Development Plan to cease (t = T).

Downstream Facilities means any petroleum processing facilities after the Valuation Point and before the earlier of the first point of arm’s length sale and the first available CUP.

1. The petroleum valuation (PV) shall be:

(a)        calculated at (and all estimates required therefor shall be calculated as at) the date of commencement of production; and

(b)        calculated in United States dollars per unit of undifferentiated hydrocarbons with respect to the following formula:

NCFt = VDPt - ECCt - OCt - CDCt - PVt x  QHt

by substituting and solving for PV the equation

where:

T

∑

t=0

NCFt =0 (1+r)

r = 14% for floating gas-to-liquids technology and 10.5% for an export pipeline;

NCF is net cash flow before tax;

VDP is the total market value of the downstream product, at the first point of arm’s length sale, or the first available CUP, in that year;

ECC is expenditures made for items which normally have a useful life of more than one (1) year incurred by the owners of the Downstream Facilities in the year for which NCF is being calculated (including, but not limited to, feasibility and engineering costs and other costs incurred for the purposes of designing and constructing the Downstream Facilities (and in the first year, those costs incurred prior to the start of the Calculation Period)), but only to the extent such are incurred in respect of the Downstream Facilities before the date of commencement of production;

OC is an amount equal to the operating costs (including taxes other than taxes on income, profit or gain and further including expenditures to maintain, repair and replace equipment necessary for the operation of the Downstream Facilities) incurred by the owners of the Downstream Facilities in that year, but only to the extent such are incurred on and from the date of commencement of production in respect of the Downstream Facilities, but does not include:

(a)           any cost or provision against the eventual costs of decommissioning the Downstream Facilities;

(b)           depreciation of capital costs; and

(c)            the cost of natural gas used in the production process;

CDC in the last year of production is the estimated costs of decommissioning the Downstream Facilities, and otherwise is zero;

QH is the quantity of undifferentiated hydrocarbons that, in that year, passed the Valuation Point.

1. Where that part of the undifferentiated hydrocarbon stream which is processed as condensate or LPG is processed under a fixed processing fee arrangement, with those revenues being passed upstream, then the following adjustments shall be taken into account in the calculation in paragraph 6:

(a)        VDP shall exclude the value of the condensate or LPG but include the amount of tolling fees paid in that year in respect of the processing services supplied to a Sunrise Joint Venturer in respect of production of that condensate or LPG; and

(b)        QH shall exclude the quantity of undifferentiated hydrocarbons which results in production of that condensate or LPG for which tolling fees were paid.

1. All costs and estimates of costs used for the purposes of the calculation in paragraph 6, including any tolling fees charged under paragraph 7, shall be not more than those which

would be directly and necessarily incurred by a reasonable and prudent operator in an arm’s length transaction.

1. Where the average realised price for downstream product over the previous two years differs by more than 10% from the average price over that period as included in the calculations under paragraph 6, then either Timor-Leste or Australia may initiate a review of these calculations by the Regulatory Authorities, in accordance with the following:

(a)        Any review shall occur not within two years of any prior review, and the first review shall not occur earlier than five years following the commencement of production from Greater Sunrise.

(b)        The calculations under paragraph 6 shall be re-undertaken from the beginning of the Calculation Period, taking into account actual realised downstream product prices to date, and any new estimates of downstream product prices.

(c)        Where a new petroleum valuation is determined under this review process, this new valuation shall apply prospectively from the date of recalculation.

ANNEX IV

Dispute Resolution Procedure

(a)            An arbitral tribunal to which a dispute is submitted pursuant to Article 26 (2) shall consist of three persons appointed as follows:

1. Timor-Leste and Australia shall each appoint one arbitrator;

Within sixty (60) days after the giving of such notice the respondent country shall notify the country instituting proceedings of the name of the arbitrator appointed by the respondent country.

(c)        If, within the time limits provided for in sub-paragraphs (a) (ii) and (iii) and paragraph (b) of this Annex, the required appointment has not been made or the required approval has not been given, Timor-Leste or Australia may request the President of the International Court of Justice to make the necessary appointment.  If the President is a citizen or permanent resident of Timor-Leste or Australia or is otherwise unable to act, the Vice-President shall be invited to make the appointment. If the Vice-President is a citizen or permanent resident of Timor-Leste or Australia or is otherwise unable to act, the Member of the International Court of Justice next in seniority who is not a citizen or permanent resident of Timor-Leste or Australia shall be invited to make the appointment.

(d)        In case any arbitrator appointed as provided for in this Annex shall resign or become unable to act, a successor arbitrator shall be appointed in the same manner as prescribed for the appointment of the original arbitrator and the successor shall have all the powers and duties of the original arbitrator.

(j)             An award shall be final and binding on Timor-Leste and Australia.

ANNEX V

Expert Determination Procedure

1. If no agreement is reached on the appointment of an expert within the period specified in Article 26, each Government shall forthwith exchange with the other a list of not more than three independent experts, putting them in order of preference. In each list, the first shall have three points, the second two points and the third one point. The expert having the greatest number of points from the two lists shall be appointed.

1. If two or more of the experts named on the lists exchanged by the Governments share the greatest number of points, the Governments shall, within 30 days of exchange, by agreement or, failing that, by lot, select which of the experts shall be appointed to decide the matter in question.

1. If the expert to be appointed is unable or unwilling to act, or fails, in the opinion of both Governments, to act within a reasonable period of time to decide the matter in question, then the expert with the greatest number of points among the experts remaining shall be the expert to decide the matter in question. If two or more such experts share the greatest number of points, both Governments shall, by unanimous agreement or by lot, select which expert shall be appointed as the expert to decide the matter in question.

1. If a Government fails to respond to any request or notice within the time specified under this Annex, the Government shall be deemed to have waived its rights in respect of the subject of the request or notice but nevertheless shall be bound by the actions of the other Government in selecting an expert and by the decision of the expert.

1. The task of the expert is to reach an independent determination of whatever matters are in question. Where the matter in dispute is in relation to technical redetermination of the Apportionment Ratio pursuant to Article 8, the expert’s decision must be made in accordance with any technical procedures and calculation formula pertaining to redetermination as set out in the relevant Joint Venturers’ Agreement.

1. The expert may engage independent contractors to undertake work which is necessary to enable the expert to reach a decision, provided that any contractor nominated by the expert for that purpose is approved by the Governments and gives an undertaking that neither it nor any of its personnel has a conflict of interest which would prevent it from undertaking the work.

1. The fees and costs of the expert shall be paid initially by the Government which first:

(a)            initiated the redetermination of the Apportionment Ratio; or

(b)           disagreed with the measurement, pursuant to Article 24, of quantities of gas and liquids;

and shall be recoverable from the Unit Operator. The latter shall be required to use best efforts to reimburse the initial payer within 12 months of the payment of those fees and costs.

1. Except as set out in this Agreement, the expert shall establish its own procedures. The expert shall only meet with a Government jointly with the other Government.  All communications
