(1) The effect of ORS 24.260 to 24.335 may be varied by agreement of the parties made before or after commencement of an action or distribution proceeding or the entry of judgment. The right of the parties to vary the effect of ORS 24.260 to 24.335 includes, but is not limited to, the selection of the date and time for conversion or of a specified rate of exchange to be applied to a particular transaction or a portion thereof and, after the entry of judgment, any agreement as to how the judgment is to be satisfied.
(2) Parties to a transaction may agree upon the money to be used in a transaction giving rise to a foreign-money claim and may agree to use different moneys for different aspects of the transaction. Stating the price in a foreign money for one aspect of a transaction does not alone require the use of that money for other aspects of the transaction.
