10. Agreement to sell at valuation.

(1) Where there is an agreement to sell goods on the terms that the price is to be fixed by the valuation of a third party and such third party cannot or does not make such valuation, the agreement is thereby avoided:
Provided that, if the goods or any part thereof have been delivered to, and appropriated by, the buyer, he shall pay a reasonable price therefor.

(2) Where such third party is prevented from making the valuation by the fault of the seller or buyer, the party not in fault may maintain a suit for damages against the party in fault.
