To place an order for the Goods, Buyer shall submit to PMAD a written purchase order (each, a “Purchase Order”) specifying the number of units of each Good that Buyer wishes to purchase and the requested date of pick-up. PMAD reserves the right to accept or reject and Purchase Order, or any portion thereof. PMAD’s acceptance of a Purchase Order shall be deemed to have occurred upon PMAD rendering to Buyer an invoice with respect to such Purchase Order (each, an “Invoice”), which Invoice shall specify, among other things, the number of units of each Good ordered pursuant to such Purchase Order, the per unit price for each such Good, the corresponding total amount due to PMAD with respect to such Purchase Order and the estimated date when PMAD anticipates being able to fulfill such Purchase Order. Each Invoice shall be binding on Buyer unless Buyer delivers to PMAD a written objection to such Invoice within ten (10) business days after Buyer’s receipt thereof.
