4-2-614.    Substituted performance.
    (1)  Where  without fault of either party the agreed berthing, loading, or  unloading facilities fail or an agreed type of carrier becomes  unavailable or the agreed manner of delivery otherwise becomes  commercially impracticable but a commercially reasonable substitute is  available, such substitute performance must be tendered and accepted.
(2)  If  the agreed means or manner of payment fails because of domestic or  foreign governmental regulation, the seller may withhold or stop  delivery unless the buyer provides a means or manner of payment which is  commercially a substantial equivalent. If delivery has already been  taken, payment by the means or in the manner provided by the regulation  discharges the buyer's obligation unless the regulation is  discriminatory, oppressive or predatory.
