PAYOR BANK'S RIGHT TO SUBROGATION ON IMPROPER PAYMENT

If a payor bank has paid an item over the order of the drawer or

maker to stop payment, or after an account has been closed, or

otherwise under circumstances giving a basis for objection by the

drawer or maker, to prevent unjust enrichment and only to the extent

necessary to prevent loss to the bank by reason of its payment of

the item, the payor bank is subrogated to the rights:

(1) Of any holder in due course on the item against the

drawer or maker;

(2) Of the payee or any other holder of the item against

the drawer or maker either on the item or under

transaction out of which the item arose; and

(3) Of the drawer or maker against the payee or any other

holder of the item with respect to the transaction of

which the item arose.
