Upon receipt of any such written notice of non-conformance, Atrix shall either acknowledge that the subject Product does not meet the specifications or resample the lot or batch of the Product in question and have such samples tested by an independent laboratory mutually agreeable to the Parties. If such samples fail to meet the specifications, then Atrix shall, at Block's option, either replace the non-conforming Licensed Product at no additional cost to Block as soon as reasonably possible or refund Block's payment for said non-conforming Product.

The payment by Block of an invoice for any shipment delivered at the Block facility to which the shipment was made prior to actual inspection and acceptance of that shipment shall not be deemed as an act of acceptance by Block.
