Artikel 11A

Interest on short-term credits at the rate of 4 per cent. per annum for the period since the date to which such interest was last paid to the Foreign Bank Creditor or the date of termination of the latest of the previous Agreements applicable thereto (whichever be the later) up to the date of this Agreement shall, at the option of the Foreign Bank Creditor concerned, either
(i) as of the date of this Agreement be added to the principal of the relative short-term credit and form part thereof for the purpose of adherence to and for all other purposes of this Agreement, or
(ii) be postponed and fall due in the relative foreign currency upon the termination of this Agreement, provided however that at any time prior to such termination the Foreign Bank Creditor may be paid pursuant to the provisions of Clause 10 hereof all or any part of such postponed interest in German currency (converted at the official middle rate quoted in the Federal Republic one working day previous to the day on which payment is actually made).
Each Foreign Bank Creditor, upon giving notice to his German Debtor of adherence to this Agreement, shall at the same time notify such Debtor which of the options the Creditor elects to exercise and, if no election is so notified, the Creditor shall be deemed to have elected to exercise option (i).
