or other latent medical conditions. It is further agreed by Seller that
Purchaser has not waived and does not by reason of this Agreement or otherwise
waive any non-contractual common law or statutory claim for indemnity or
contribution which Purchaser might in the future assert against Seller arising
out of a product liability claim of any nature asserted against Purchaser
relating to products sold by Seller.
