Artikel 8

(a). The contract price, including the value of sub-contracts hereunder, does not include any tax or duty which the Government of the United States and the Government of the Netherlands have agreed in the agreement dated 7 March 1952 as it may be amended from time to time and the agreed procedures thereunder shall not be applicable to expenditures in the Netherlands by the United States or any other tax or duty not applicable to this contract under the laws of the Netherlands. If any such tax or duty has been included in the contract price through error or otherwise, the contract price shall be correspondingly reduced.
(b). If, after the contract date, the Government of the United States and the Government of the Netherlands shall agree that any tax or duty included in the contract price shall not be applicable to expenditures in the Netherlands by the United States, the contract price shall be reduced accordingly.
