6.



In the event of the occurrence of any of the following, Sonangol can require Contractor to immediately propose another

Contractor company as Operator:

(a)



if the Operator, by action or omission, commits a Serious Fault in carrying out its obligations and if this fault is

not remedied to the satisfaction of Sonangol within a period of twenty-eight (28) days with effect from the date

of receipt by the Operator of written notice issued by Sonangol requesting the Operator to remedy such fault (or

within a greater period of time if so specified in the notice, or as agreed later by Sonangol);



(b)



if sentence has been passed in court declaring the bankruptcy, liquidation or dissolution of the Operator, or if, in

the court action taken in order to obtain such declaration, any injunction has been granted or any interim judicial

ruling has been made, which prevents Operator from fulfilling its obligations under the Agreement;

17



(c)



if the Operator undertakes the legal procedures established to prevent bankruptcy or without just cause ceases

payment to creditors;



(d)



if the Operator terminates or if there is strong evidence that it intends to terminate its activities or a significant

portion thereof, and, as a result, fails to fulfil its obligations under the Agreement. If said strong evidence that



the Operator intends to terminate its activities exists, the Operator shall be given a period of fifteen (15) days

with effect from the date of receipt by the Operator of written notice issued by Sonangol, or such greater period

of time if so specified in the notice, in which to refute such strong evidence to the satisfaction of Sonangol.

7.



If Contractor, in accordance with paragraph 6, does not comply with the obligation to propose another Operator from

among its members within thirty (30) days from the date when Sonangol gave notice to Contractor, Sonangol may freely

Contractor’s rate of return shall be determined at the end of each Quarter after the date of Commercial Discovery on the

basis of the accumulated compounded net cash flow for the Contract Area, using the following procedure:

(a)



Contractor’s net cash flow computed in U.S. dollars for the Contract Area for each Quarter is:

(i)



the value received and actually lifted by Contractor for all Crude Oil from the Contract Area in that

Quarter at the Market Price;



(ii)



minus Petroleum Production Tax, Petroleum Income Tax and Petroleum Transaction Tax;

19



(iii)



minus all expenditures incurred in respect the Contract Area.



(b)



Contractor’s net cash flow for each Quarter are compounded and accumulated according with 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 2.41%, 3.56%, 4.66%, 6.78%, 8.78% and 10.67%

which correspond to annual compound rates (“DA”) of 10%, 15%, 20%, 30%, 40% and 50%, respectively, as referred to in

previous paragraph.

5.



The Contractor rate of return in any given Quarter 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.



6.



The payment to Contractor and the calculation of the production allowance in a given Quarter shall be in accordance with

the table in paragraph 3 above using the Contractor Group’s rate of return as per this article in the preceding Quarter.



7.



It is possible for the Contractor rate of return to decline as a result of negative cash flow in a Quarter with the

consequence that the payment to Contractor and the calculation of the production allowance would increase in the

subsequent Quarter.

20



8.



Pending finalization of accounts, the payment to Contractor and the calculation of the production allowance shall be

calculated on the basis of provisional estimates, if necessary, of deemed rate of return as approved by Sonangol.

Adjustments shall be subsequently effected in accordance with the procedure to be established by agreement between

Sonangol and the Contractor.

Article 11

(Petroleum Operations costs and expenses)



Except as otherwise provided for in this Agreement. the costs and expenses incurred in the Petroleum Operations, as well as any

losses and risks derived therefrom, shall accrue to or be borne by Contractor, and Sonangol shall not be responsible to bear or

repay any of the aforesaid costs, expenses and risks.

such procedures and regulations.



5.



In any event, the agreed lifting procedures and regulations, as provided in the previous paragraph, shall always comply

with the Law.



6.



In the case of more than one (1) quality of Crude Oil in the Contract Area, Sonangol and Contractor shall, unless they

mutually agree that the Crude Oil should be commingled, lift each of the Crude Oil qualities in proportion to their

respective total liftings from the Contract Area. In determining these proportions any Petroleum belonging to Sonangol as

1.



During the Initial Exploration Phase Contractor shall perform a seismic program covering 1,500 Km(2) of 3D “longoffset” seismic, with an offset that varies between eight (8) kilometers and ten (10) kilometers. Sonangol agrees that such

obligation has been fulfilled through the acquisition of existing seismic.



2.



During the Initial Exploration Phase Contractor shall drill, to geological horizons defined in the Approved Work Plan and

Budget, four (4) Exploration Wells in four (4) different prospects, one of which (subject to paragraph 4) shall have a presalt objective.



3.



In the event Contractor elects to extend the Exploration Period into the Optional Exploration Phase, Contractor shall be

required to drill, to geological horizons defined in the Approved Work Plan and Budget, two (2) Exploration Wells, one

of which (subject to paragraph 4) shall have a pre-salt objective.



4.



In the event Contractor exceeds the minimum work obligations described in the preceding paragraphs during the Initial

Exploration Phase, then such excess shall be credited against the minimum work obligations for the Optional Exploration

Phase. In the event that, prior to any Commercial Discovery, Contractor elects to drill more than one Exploration Well

with a pre-salt objective, such additional pre-salt Exploration Well shall constitute one of the Exploration Wells which

Contractor is required to drill pursuant to paragraph 2 or 3 (as the case may be) and the drilling of such additional pre-salt



Exploration Well shall satisfy the obligation of Contractor to drill one Exploration Well of any kind.

5.



Without prejudice to paragraph 4 of Article 6, in the event Contractor fails to satisfy the minimum work obligations

referred to in this Article within the deadlines specified in Article 6, Contractor shall be deemed, unless otherwise agreed

by Sonangol, to have voluntarily terminated activities

25



and withdrawn from all of the Contract Area not already converted into a Development Area(s).

6.



If Contractor withdraws from all of the Contract Area before drilling the minimum number of Exploration Wells

undertaken by it under this Article, Contractor shall be obligated to pay Sonangol an amount equal to fifty million U.S.

Dollars (U.S. $50,000,000) if the pre-salt Exploration Well is not so drilled, and an amount equal to thirty two million

five hundred thousand U.S. Dollars (U.S. $32,500,000) for each of the other three (3) Exploration Wells not so drilled.



7.



Contractor shall be required to incur the following minimum Exploration Expenditures:

(a)



Initial Exploration Phase – one hundred and forty seven million five hundred thousand U.S. Dollars (U.S.

$147,500,000);



(b)



Optional Exploration Phase – eighty two million five hundred thousand U.S. Dollars (U.S. $82,500,000).



8.



If Contractor fulflls the minimum work obligations referred to in paragraphs 2 and 3 of this Article relating to each phase

of the Exploration Period, then Contractor shall be considered as having fulfilled the minimum Exploration Expenditures

set forth in the previous paragraph.



9.



Each Exploration Well referred to in this Article shall test all productive horizons agreed to by Sonangol and Contractor,

unless diligent test efforts consistent with sound and normal oil industry practices indicate that it is technically

impracticable to reach and/or test any such horizons.



10.



During the drilling of Wells under this Agreement, Contractor shall keep Sonangol informed of the progress of each

Well, its proposals for testing and the results of such tests, and if Sonangol so requests, shall test any additional

prospective zones within the agreed Well depth provided that such tests shall be consistent with professional rules and

standards which are generally accepted in the international petroleum industry and not

26



interfere with the safety and efficiency of the Petroleum Operations planned by Contractor. Such tests shall be at

Contractor’s expense and shall be credited towards fulfilling the mandatory work program.

11.



If any obligatory Exploration Well is abandoned due to technical difficulties and, at the time of such abandonment, the

Exploration Expenditures for such Well have equalled or exceeded fifty million U.S. dollars (U.S.$50,000,000) if such

Well is a Well with a pre-salt objective, or thirty two million five hundred thousand U.S. dollars (U.S.$32,5000,000) in

the case of any other Well, for all purposes of this Agreement Contractor shall be considered to have fulfilled the work

requirement in respect of one (1) Exploration Well and all costs of the Exploration Well shall be considered part of the

Exploration Expenditures set forth in paragraphs 6 and 7 of this Article. If any obligatory Exploration Well is abandoned

due to technical difficulties, and if at the time of such abandonment the Exploration Expenditures for such Well are less

than fifty million U.S. dollars (U.S.$50,000,000) if such Well is a Well with a pre-salt objective, or thirty two million five

hundred thousand U.S. dollars (U.S.$32,500,000) in the case of any other Well, then Contractor shall have the option

either to:

(a)



drill a substitute Well at the same or another location in which case the Exploration Expenditures for both the

original Well and the substitute Well shall be credited against Contractor’s minimum Exploration Expenditures

set forth in paragraphs 6 and 7 of this Article; or



(b)



pay Sonangol an amount equal to the difference between (i) fifty million U.S. dollars (U.S.$50,000,000) if such



Well is a Well with a pre-salt objective, or thirty two million five hundred thousand U.S. dollars

(U.S.$32,500,000) in the case of any other Well, and (ii) the amount of Exploration Expenditures actually spent

in connection with such Well.

27



In this case, for all purposes of the Agreement, Contractor shall be considered to have fulfilled the work obligation in

respect of one (1) Exploration Well and the total amount of fifty million U.S. dollars (U.S.$50,000,000) if such Well is a

Well with a pre-salt objective, or thirty two million five hundred thousand U.S. dollars (U.S.$32,500,000) in the case of

any other Well, shall be considered part of the minimum Exploration Expenditures set forth in paragraphs 6 and 7 of this

Article.
