§ 2725.  Statute of limitations in contracts for sale.
        (a)  General rule.--An action for breach of any contract for
     sale must be commenced within four years after the cause of
     action has accrued. By the original agreement the parties may
     reduce the period of limitation to not less than one year but
     may not extend it.
        (b)  Accrual of cause of action.--A cause of action accrues
     when the breach occurs, regardless of the aggrieved party's lack
     of knowledge of the breach. A breach of warranty occurs when
     tender of delivery is made, except that where a warranty
     explicitly extends to future performance of the goods and
     discovery of the breach must await the time of such performance
     the cause of action accrues when the breach is or should have
     been discovered.
        (c)  New action after termination of another.--Where 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 breach such 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)  Laws and actions unaffected by section.--This section
     does not alter the law on tolling of the statute of limitations
     nor does it apply to causes of action which have accrued before
     this title becomes effective.
