Artikel (1)

(a). The States which are parties to the Convention on the date of its entry into force, together with any other States which may become members of the Organization during the period ending on the 31st of December, 1954, shall between them contribute the whole of the sums required by such provisional budgetary arrangements as the Council may take under paragraph (1) of Article 4.
(b). The contributions of the States, which are members of the Organization when the Council first makes such provisional budgetary arrangements, shall be provisionally assessed on the basis set out in paragraph (2) of Article 4, subject to the provisoes mentioned in (i) and (ii) of sub-paragraph (b) of paragraph 1 of Article VII of the Convention, except that in proviso (i) thirty per cent shall be deemed to be substituted for twenty-five per cent.
(c). The contributions of the States which become members of the Organization during the period between the first occasion on which provisional budgetary arrangements have been made and the 31st of December, 1954, shall be provisionally assessed in such a manner that the relative proportions between the provisional contributions of all Member States are the same as between the percentage figures set out in paragraph (2) of this Annex. Such contributions will serve either, as provided for in sub-paragraph (d) below, to reimburse subsequently part of the provisional contributions previously paid by the other Member States, or to meet additional budgetary appropriations approved by the Council during that period.
(d). The final contributions due for the period ending on the 31st of December, 1954, from all the States which are members of the Organization on that date shall be retroactively assessed after that date on the basis of the total budget for the said period, so that they shall be those which they would have been if all these States had become parties to the Convention on the date of its entry into force. Any sum paid by a Member State in excess of its contribution thus retroactively assessed shall be placed to the credit of that Member State.
(e). If all the States specified in the scale set out in paragraph (2) of this Annex have become members of the Organization before the 31st of December, 1954, their percentage contributions to the total budget for that period shall be those set out in that scale.
