6. CASTLE CREATIONS LIMITED WARRANTY. Subject to the limitations and conditions hereinafter set forth, CASTLE warrants, at the time of delivery by CASTLE, each product to be free from (i) defects in material or workmanship and (ii) defects in design that in view of the state-of-the-art as of the date of manufacture should have been foreseen; provided, however, that the defect must be discovered and reported within twelve (12) months of date of purchase for new parts. The entire extent of CASTLE'S liability shall be limited to reimbursing Buyer for its costs of purchasing a rebuilt, overhauled, repaired or serviceable product from CASTLE, or at CASTLE’S sole discretion, the actual repair of the product. If CASTLE elects not to repair the product and if no rebuilt, overhauled, repaired or serviceable product is, at CASTLE'S sole determination, timely available then CASTLE may provide an equivalent CASTLE product. The product to be replaced or repaired must in all instances be returned, shipping prepaid, to CASTLE, unless otherwise directed by CASTLE. CASTLE'S LIMITED WARRANTY will apply to any product repaired or replaced by a CASTLE pursuant to CASTLE'S LIMITED WARRANTY; however, the applicable warranty for such product repaired or replaced shall be limited to the unexpired portion of CASTLE'S LIMITED WARRANTY as applicable.
