(b)cash benefits shall, where appropriate, be provided by the competent institution as determined by the rules of paragraph 2, in accordance with the legislation which it administers. However, upon agreement between the competent institution and the institution of the place of residence, such benefits may be provided by the latter institution on behalf of the former, in accordance with the legislation of the competent State.

(a)where the pensioner is entitled to the said benefits under the legislation of a single Member State, the cost shall be borne by the competent institution of that State;
(b)where the pensioner is entitled to the said benefits under the legislation of two or more Member States, the cost thereof shall be borne by the competent institution of the Member State to whose legislation the pensioner has been subject for the longest period of time; should the application of this rule result in several institutions being responsible for the cost of benefits the cost shall be borne by the institution administering the legislation to which the pensioner was last subject.
