Section III. Interest
Article 78
If a party fails to pay the price or any other sum that is in arrears, the other party is entitled to interest on it, without prejudice to any claim for damages recoverable under article 74.
Section IV. Exemptions
Article 79
(1) A party is not liable for a failure to perform any of his obligations if he proves that the failure was due to an impediment beyond his control and that he could not reasonably be expected to have taken the impediment into account at the time of the conclusion of the contract or to have avoided or overcome it or its consequences.
(2) If the party's failure is due to the failure by a third person whom he has engaged to perform the whole or a part of the contract, that party is exempt from liability only if:
(a) he is exempt under the preceding paragraph; and
(b) the person whom he has so engaged would be so exempt if the provisions of that paragraph were applied to him.
(3) The exemption provided by this article has effect for the period during which the impediment exists.
(4) The party who fails to perform must give notice to the other party of the impediment and its effect on his ability to perform. If the notice is not received by the other party within a reasonable time after the party who fails to perform knew or ought to have known of the impediment, he is liable for damages resulting from such non-receipt.
(5) Nothing in this article prevents either party from exercising any right other than to claim damages under this Convention.
Article 80
A party may not rely on a failure of the other party to perform, to the extent that such failure was caused by the first party's act or omission.
Section V. Effects of avoidance
Article 81
(1) Avoidance of the contract releases both parties from their obligations under it, subject to any damages which may be due. Avoidance does not affect any provision of the contract for the settlement of disputes or any other provision of the contract governing the rights and obligations of the parties consequent upon the avoidance of the contract.
