10. RECOVERY OF OPERATING COSTS AND SHARING OF PETROLEUM PRODUCTION

10.1 The allocation of Available Crude Oil shall be calculated on a Contract Area basis for Royalty Oil, Cost Oil and Profit Oil. This allocation of Available Crude Oil shall be in accordance with the Accounting Procedure, the Allocation and Lifting Procedure and this Clause 10 as follows:

(a) Royalty Oil shall be allocated to the State from the first day of Production, based on the daily total of Available Crude Oil from a Contract Area, set at a rate of two percent (2%);

(b) Cost Oil shall be allocated to the Contractor in such quantum as will generate an amount of Proceeds sufficient for recovery of Operating Costs in each Contract Area. All costs will be recovered in United States dollars through Cost Oil allocation;

(c) Cost Oil shall be not more than eighty percent (80%) of Available Crude Oil in each Contract Area less deduction of Royalty Oil in any accounting period;

(d) Profit Oil, being the balance of Available Crude Oil after deducting Royalty Oil and Cost Oil, shall be allocated to each Party based on the pre-tax, nominal rate of return calculated on a quarterly basis for the Contract Area in accordance with the following sliding scale:

Contractor's Rate of Return for Contract Area (%per annum)	Government Share of Profit Oil	Contractor Share of Profit Oil
<16%	0%	100%
>=16 %< 19%	10%	90%
>=19 %< 23%	20%	80%
>=23 %< 26%	40%	60%
>=26%	50%	50%

10.2 Beginning at the date of Commercial Discovery, Contractor's rate of return shall be determined at the end of each Quarter on the basis of the accumulated compounded net cash flow for each Contract Area, using the following procedure:

(a) The Contractor's net cash flow for a Contract Area for each Quarter is:

(i) The sum of the Contractor's Cost Oil and share of Contract Area Profit Oil regarding the Petroleum actually lifted in that Quarter at the Realizable Price;

(ii) Minus Operating Costs;

(b) For this computation, neither any expenditure incurred prior to the date of Commercial Discovery for a Contract Area nor any Exploration Expenditure shall be included in the computation of the Contractor's net cash flow.

(c) The Contractor's net cash flows for each Quarter are compounded and accumulated for a Contract Area from the date of the Commercial Discovery according to the following formula:

ACNCF (Current Quarter) =

(100% + DQ) x ACNCF (Previous Quarter) + NCF (Current Quarter) 100%

where:

ACNCF = accumulated compounded net cash flow

NCF = net cash flow

DQ = quarterly compound rate (in percent)

The formula will be calculated using quarterly compound rates (in percent) of 3.78%, 4.45%, 5.31%, and 5.95%, which correspond to annual compound rates ("DA") of 16%, 19%, 23%, and 26%, respectively.

(d) The Contractor's rate of return in any given Quarter for a Contract Area shall be deemed to be between the largest DA which yields a positive or zero ACNCF and the smallest DA which causes the ACNCF to be negative.

(e) The sharing of Profit Oil from a Contract Area between the State and the Contractor in a given Quarter shall be in accordance with the scale in paragraph (a) above using the Contractor's deemed rate of return as per paragraph (c) in the immediately preceding Quarter.

(f) In a given Contract Area, it is possible for the Contractor's deemed rate of return to decline as a result of negative cash flow in a Quarter with the consequence that Contractor's share of Profit Oil from that Contract Area would increase in the subsequent Quarter.

(g) Pending finalization of accounts, Profit Oil from the Contract Area shall be shared on the basis of provisional estimates, if necessary, of a deemed rate of return as approved by the National Petroleum Agency. Adjustments shall be effected with the procedure subsequently to be adopted by the National Petroleum Agency.

10.3 The quantum of Available Crude Oil to be allocated to each Party under this Contract shall be determined at the Delivery Point.

10.4 Each Party shall lift and dispose of its allocation of Available Crude Oil in accordance with the Allocation and Lifting Procedures as provided in Schedule 3. In the event of any reconciliation, the records of the National Petroleum Agency shall be the official, final and binding records.

10.5 Allocation of Royalty Oil and Profit Oil shall be in the form of delivery of Production of Petroleum to the National Petroleum Agency and the National Petroleum Agency or other appropriate authority shall issue receipts for such delivery within thirty (30) days of lifting such Royalty Oil and Profit Oil. These receipts are issued by the National Petroleum Agency or other appropriate authority on behalf of the Government of Sao Tome and Principe.

10.6 Any Party may, at the request of any other Party, lift such other Party's Available Crude Oil, pursuant to Clause 10.3, and the lifting Party, within thirty (30) days, shall transfer to the account of the non-lifting Party the Proceeds of the sale to which the non-lifting Party is entitled. Overdue payments shall bear interest at the rate of LIBOR plus two percent (2%).

10.7 The State may sell to the Contractor all or any portion of its allocation of Available Crude Oil from the Contract Area under mutually agreed terms and conditions at the Realizable Price.

10.8 The Parties shall meet as and when agreed in the Allocation and Lifting Procedures to reconcile all Petroleum produced, allocated and lifted during the period in accordance with the Allocation and Lifting Procedures set forth in Schedule 3.

10.9 Notwithstanding the above, in lieu of lifting the State's Profit Oil and/or Royalty Oil, the State, upon one hundred eighty (180) days advance notice to the Operator, issued by the National Petroleum Agency, may elect to receive the State's allocation of Profit Oil and/or Royalty Oil in cash based on the Realizable Price rather than through lifting, regardless of whether or not the Contractor sells the State's Profit Oil and/or

Royalty Oil to a third party. If the State elects to receive cash in lieu of lifting, the Operator shall lift the State's allocation of Profit Oil and/or Royalty Oil and pay into the National Petroleum Account cash in respect of such lifting within thirty (30) days from the end of the month in which the lifting occurred. Every six (6) months, the State may elect to have an entity designated by the State to resume lifting the State's allocation of Profit Oil and/or Royalty Oil, upon one hundred eighty (180) days notice to the Operator, prior to the date the State elects to have an entity, designated by the State, to resume lifting. In the event the State elects to receive its allocation of Profit Oil and or/Royalty Oil in cash, then the Contractor may charge a marketing fee to be mutually agreed.

11. VALUATION OF CRUDE OIL

11.1 The valuation of Crude Oil shall reflect the true market value based on arm's length transactions for the sale of the Crude Oil.

11.2 Save as otherwise provided in this Contract, Crude Oil Production shall be valued in accordance with the following procedures:

(a) On the attainment of commercial production of Crude Oil, each Party shall engage the services of an independent laboratory of good repute to undertake a qualitative and quantitative analysis of such Crude Oil.

(b) When a new Crude Oil stream is produced, a trial marketing period shall be designated which shall extend for the first six (6) month period during which such new stream is lifted or for the period of time required for the first ten (10) liftings, whichever is longer. During the trial marketing period the Parties shall:

(i) collect samples of the new Crude Oil upon which the qualitative and quantitative analysis shall be performed as provided in Clause 1l.2(a);

(ii) determine the approximate quality of the new Crude Oil by estimating the yield values from refinery modeling;

(iii) market, in accordance with their entitlement to the new Crude Oil and to the extent that one Party lifts the other Party's allocation of Available Crude Oil, and payments therefore, shall be made by the buyers to the Operator who will be responsible for distributing to the other Parties in accordance with their entitlement, Cost Oil and Profit Oil and the Contractor's accounting shall reflect such revenues, in accordance with Clause 10;

(iv) provide information to a third party who shall compile the information and maintain all individual Party information confidential, with regard to the marketing of the new Crude Oil, including documents which verify the sales price and terms of each lifting; and

(v) apply the actual F.0.B. sales price to determine the value for each lifting which F.O.B. sales pncmg for each lifting shall continue, as the

Realizable Price, after the trial marketing period until the Parties agree to a valuation of the new Crude Oil but in no event longer than ninety (90) days after conclusion of the trial marketing period.

(c) As soon as practicable but in any event not later than sixty (60) days after the end of the trial marketing period, the Parties shall meet to review the qualitative and quantitative analysis, yield and actual sales data. Each Party may present a proposal for the valuation of the new Crude Oil. A valuation formula for the Realizable Price shall be agreed to by the Parties not later than nine (9) months after the first lifting. It is the intent of the Parties that such prices shall reflect the true market value based on arm's length transactions for the sale of the new Crude Oil. The valuation formula, as determined hereinbefore (including the product yield values), shall be mutually agreed within thirty (30) days of the aforementioned meeting, failing which, it shall be referred to a mutually agreed independent expert who shall have the appropriate international oil and gas experience and who will resolve and settle the matter in a manner as he shall in his absolute discretion think fit and the decision of the expert shall be final and binding on the Parties. If, after a period of thirty (30) days, the Parties are unable to agree on the identity of the expert, such expert shall be appointed by the International Centre for Expertise in accordance with the provisions for the appointment of experts under the Rules for Expertise of the International Chamber of Commerce.

(d) Upon the conclusion of the trial marketing period, the Parties shall be entitled to lift their allocation of Available Crude Oil pursuant to Clause 10.3 and the Allocation and Lifting Procedures set forth in Schedule 3.

(e) When a new Crude Oil stream is produced from the Contract Area and is commingled with an existing Crude Oil produced, which has an established Realizable Price basis, then such basis shall be applied to the extent practicable for determining the Realizable Price of the new Crude Oil. The Parties shall meet and mutually agree on any appropriate modifications to such established valuation basis, which may be required to reflect any change in the market value of the Crude Oils as a result of commingling.

11.3 If, in the opinion of either the National Petroleum Agency or the Contractor, an agreed price valuation method fails to reflect the market value of Crude Oil produced in the Contract Area, then such Party may propose to the other Party modifications to such valuation method once in every six (6) months but in no event more than twice in any Calendar Year. The Parties shall then meet within thirty (30) days of such proposal and mutually agree on any modifications to such valuation within thirty (30) days from such meeting, failing which, the issue shall be referred to a mutually agreed independent expert who shall have the appropriate international oil and gas experience and who will resolve and settle the matter in a manner as he shall in his absolute discretion think fit and the decision of the expert shall be final and binding on the Parties. If after a period of thirty (30) days, the Parties are unable to agree on the identity of the expert, such expert shall be appointment by the International Centre for Expertise in accordance with the provisions for the appointment of experts under the Rules for Expertise of the International Chamber of Commerce.

11.4 Segregation of Crude Oils of different quality and/or grade shall, by agreement of the Parties, take into consideration, among other things, the operational practicality of segregation and the cost benefit analysis thereof. If the Parties agree on such segregation the following provisions shall apply:

(a) any and all provisions of this Contract concerning valuation of Crude Oil shall separately apply to each segregated Crude Oil produced; and

(b) each grade or quality of Crude Oil produced and segregated in a given year shall contribute its proportionate share to the total quantity designated in such year as Royalty Oil, Cost Oil and Profit Oil.
