§ 2A506.  Statute of limitations.
        (a)  General rule.--An action for default under a lease
     contract, including breach of warranty or indemnity, must be
     commenced within four years after the cause of action accrued.
     By the original lease contract the parties may reduce the period
     of limitation to not less than one year.
        (b)  Accrual of cause of action.--A cause of action for
     default accrues when the act or omission on which the default or
     breach of warranty is based is or should have been discovered by
     the aggrieved party, or when the default occurs, whichever is
     later. A cause of action for indemnity accrues when the act or
     omission on which the claim for indemnity is based is or should
     have been discovered by the indemnified party, whichever is
     later.
        (c)  New action after termination of another.--If an action
     commenced within the time limited by subsection (a) is so
     terminated as to leave available a remedy by another action for
     the same default or breach of warranty or indemnity, the other
     action may be commenced after the expiration of the time limited
     and within six months after the termination of the first action
     unless the termination resulted from voluntary discontinuance or
     from dismissal for failure or neglect to prosecute.
        (d)  Unaffected laws and actions.--This section does not
     alter the law on tolling of the statute of limitations nor does
     it apply to causes of action that have accrued before this
     division becomes effective.
