Parts 210 and 211 and all applicable rules, regulations, guides and guidances, as well as all applicable rules, regulations, guides and guidances of the Canadian Health Protection Board; 1.3 Product(s) shall mean Ridaura in finished dosage form. 1.4 Territory shall mean Canada. 1.5 Vendor shall mean any supplier of Products to SELLER, (with the parties acknowledging that sole current Vendor is SmithKline). ARTICLE 2 - ORDERS, PRICING, PAYMENT AND ACCEPTANCE 2.1 Sale of Products. SELLER shall sell Product exclusively to BUYER for sale in the Territory and, to the extent that SELLER is able to order Product from its Vendor, shall supply all of BUYER's reasonable requirements of Product in the Territory. SELLER will effect such sales by including BUYER's reasonable requests for Products in SELLER's orders submitted to its Vendor(s). 2.2 Forecasts and Orders. (a) By September 1st of each year during the term of this Agreement, BUYER shall provide SELLER with a 12 month forecast to run from January 1st to December 31st of the next calendar year of BUYER's estimated requirements of the Product, which forecast may be updated every three (3) months. The first three (3) months of each rolling 12-month forecast or updated forecast shall be a binding order against which SELLER is authorized to order Products from its Vendor. (b) Upon receipt of BUYER's ordered Products from the Vendor, SELLER shall deliver such Products to BUYER in a timely manner. SELLER may also, in its sole discretion, request the Vendor to deliver products directly to BUYER. (c) BUYER is not obligated to buy any specific amount of Products under this Agreement and shall be obligated to purchase only those quantities for which it has submitted a binding order. 2.3 Price; Payment; Shipment. (a) Except as otherwise agreed to between BUYER and SELLER, the price for the Product ordered shall be the price 2 charged for the Products by the Vendor to SELLER. For all orders, risk of loss in transit, either from the Vendor to SELLER or from SELLER to BUYER, shall lie with BUYER. In addition, for all orders, BUYER shall be responsible for all out-of-pocket charges, taxes and other costs incurred in connection with the supply of Products to BUYER, including without limitation all freight and shipping charges, transfer costs, and sales and import taxes, levies or duties; provided, that in the case of the shipment of Products to SELLER by the Vendor, BUYER shall only be responsible for its pro rata portion of the costs incurred by SELLER (i.e., the proportion that BUYER's quantity of Products ordered bears to the total quantity of Products ordered by SELLER from the Vendor). (b) BUYER agrees to pay SELLER for the Products as set forth above, net thirty (30) days from the receipt of invoice. All payments hereunder shall be made in U.S. Dollars. 2.4 Acceptance. Within twenty-five (25) days of receipt of any Product, BUYER shall perform such samplings and tests as it deems appropriate, if any, using validated test methods to determine whether the Product meets the Product specifications agreed to between SELLER and the Vendor (e.g., those set forth in Exhibit A of the SmithKline Agreement) (the "Specifications"). SELLER shall provide certificates of analysis for each batch of Product, as provided to SELLER by the Vendor. If BUYER wishes to reject any shipment, BUYER shall within such twenty-five (25) days' time, inform SELLER in writing of its refusal to accept the lot(s), and the reasons therefor. Any Product not timely rejected shall be deemed accepted. In the event that BUYER rejects any shipment, SELLER, upon confirmation of the reasons for rejection, shall either replace the defective Products or to refund the purchase price, as SELLER may elect. If SELLER and BUYER do not agree on the rejection of Product, then either party may refer the matter for final analysis to a specialized laboratory of international reputation reasonably acceptable to both parties for the purpose of determining whether the Product meet Specifications. Any determination by such laboratory shall be binding upon both parties. 2.5 Reservation of Rights.

Said determination may be made by the governmental agency involved, or by mutual agreement of the parties following examination and review of all records pertinent to the manufacture of the Product subject to such recall.
