company shall be determined in accordance with expenses already incurred by each Party with regard to the deposit which is the purpose of the Mining Permit of which this limited liability company is the owner. This Interest shall be equal to the
ratio between expenses already financed by this Party and total expenditure already financed by the Parties as a whole. However, the cash Participation of the State shall be at most equal to 10 % of the company capital of the limited liability
company subject to the provisions of Article 14.6 below.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the sum of expenses already incurred by the State
should be greater than 10 % of the company capital of the limited liability company, any excess shall be carried to the credit of the State for future requirements in company capital by the limited liability company, or shall be considered as a
shareholders advance and shall be repaid to the State by the limited liability company when its financial situation allows. The sum of expenses already incurred by the Parties and to be included into the initial company capital of an limited
liability company shall be determined by mutual agreement between the State and BHP.



|14.2 | At the date of signature of the present Convention, the following amount shall be considered, in terms of the contract, as expenses already incurred by the
State, for exploration work carried out within the boundary: One million six hundred thousand US Dollars (1.600.000 $ US) which shall bear interest at the LIBOR rate + 2 %. These expenses may only be used by the State for the constitution of the
first limited liability company established within the framework of the present Convention.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14.3 | In accordance with Article 62 of the Mining Code, the cash participation of the State in the company capital of the limited liability company, envisaged in Article 14.1
above, shall be increased by a free participation equal to 10 % of the company capital of the limited liability company. This free Participation of the State equal to 10 % of the company capital shall have the same rights pari passu as

|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14.4 | The State shall have no obligation by virtue of its percentage free Participation stipulated in Article 14.3, to contribute to exploration and Feasibility Study
expenses or expenses related to the development of the deposit or any development works or mining expenses.

shares shall be allocated to the State free of charge so as to allow it to retain its percentage free Participation of 10 %.

financial means and/or guarantees necessary for the development and mining by the limited liability company of the deposit in proportion to this 10 % Participation and shall subscribe to any increase in company capital.

participating in the capital of the said limited liability company, and according to the procedures stipulated in Articles 14.1 to 14.5 above, choose the following formula :
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | to obtain automatically, in exchange for expenses already incurred and the free Participation of 10 % stipulated by Article 62 of the Order
pertaining to the Mining Code, 15 % of the initial company capital in the limited liability company, with the possibility of obtaining in cash from BHP an additional Participation of 5 % of company capital.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The State shall notify BHP in writing of its decision on whether to accept this formula thirty (30) days after the establishment of
the first limited liability company at the latest.

The acquisition price of the cash Participation of 5 % shall equal the
percentage of 5 % multiplied by the coverall cost of Exploration Work and the Feasibility Study relating to the deposit, and carried by BHP before the establishment of the limited liability company, increased by interest at the LIBOR rate + 2
%.

Should the State decide to acquire from BHP the additional 5 % cash Participation, payment shall be made within three
months of the establishment of the limited liability company at the latest.

Should an increase in the capital of the limited
liability company be decided by an Extraordinary General Assembly prior to First Production, 15 % of the new shares shall be allocated to the State free of charge so as to allow it to retain its initial percentage of 15 %.

The State shall have no obligation by virtue of its initial percentage of 15 % to contribute to exploration and Feasibility Study
expenses or expenses related to the development of the deposit or any development work or mining expenses up to First Production.

Should there be new investments and/or an increase in the capital after First Production, this 15 % Participation shall carry the same obligations pari passu as the Participations held by the other
shareholders in the limited liability company.

during the validity of the said limited liability company exceed 20 % of the total of the said company capital.

Parties is that the Malian tax on profits which shall be payable by BHP by virtue of the present Article 22 shall be considered as a tax credit in the meaning of the Internal Revenue Code of the United States of America. If the Internal Revenue

which can constitute a tax credit in its entirety. However, such modifications can in no circumstances have the effect of modifying the economic or other advantages granted to the State in the present Convention.

Article 33, notwithstanding any provision to the contrary in the present Convention, shall automatically be extended by a period equal to the delay caused by the force majeure event. However, it is understood that neither the State nor BHP may

|38.3 | When one or the other of the parties deems that it has been prevented from fulfilling any one of its obligations by reason of a case of force majeure, it should
immediately notify the other party of this impediment in writing, giving the reasons. The parties should take all necessary steps to ensure that there is the shortest time possible before a return to the normal execution of obligations affected by
the force majeure, subject to a party not being bound to settle disputes with third parties, including labour conflicts, unless the conditions are acceptable to it or the settlement is made compulsory following a final arbitration judgement or a
decision by a competent court of law. The State undertakes to co-operate with BHP and/or the limited liability company for a mutual settlement of any labour conflict that may arise.
