EXHIBIT 10.20 [METRA BIOSYSTEMS LOGO] INTERNATIONAL DISTRIBUTOR AGREEMENT This International Distributor Agreement (the "Agreement") is entered into in Palo Alto, California, as of April 8, 1993, between METRA BIOSYSTEMS, INC., a corporation organized under the laws of California, United States of America, with principal offices at 3181 Porter Drive, Palo Alto, California 94304, United States of America, ("Manufacturer") and Amersham K.K., an organization organized under the laws of Japan with offices at Tokyo Toyama Kaikan, 1-3, Kakusan 5-Chome, Bunkyo-ku, Tokyo 112, Japan ("Distributor"). In consideration of the mutual promises contained herein, the parties agree as follows: 1. DEFINITIONS (a) "Products" shall mean those products listed in EXHIBIT A attached hereto to be distributed solely for research purposes. Metra Biosystems may appoint other parties to develop and commercialize products for clinical use. Products may be changed, abandoned or added by Manufacturer, at Manufacturer's sole discretion, provided that Manufacturer gives ninety (90) days' prior written notice to Distributor. Manufacturer shall be under no obligation to continue the production of any Product, except as provided herein. (b) "Territory" shall mean that geographic area identified in EXHIBIT B attached hereto. 2. APPOINTMENT AND AUTHORITY OF DISTRIBUTOR (a) APPOINTMENT. Subject to the terms and conditions set forth herein, Manufacturer hereby appoints Distributor as Manufacturer's distributor for the Products in the Territory, and Distributor hereby accepts such appointment. For so long as Distributor is performing in compliance with this Agreement, Manufacturer shall not appoint any other distributor with responsibility for sale of the Products in the Territory. (b) TERRITORIAL RESPONSIBILITY. Distributor shall not promote the Products outside the Territory or establish a facility for purposes relating to the Products outside the Territory. Distributor shall forward to Manufacturer all unsolicited inquiries relating to the Products from customers or potential customers outside the Territory. (c) OTHER DISTRIBUTORS. In the event that Manufacturer receives requests for information relating to, or purchase orders for, the Products from customers or potential customers within the Territory, Manufacturer shall forward such requests or orders to Distributor. Notwithstanding the above, nothing in this Agreement shall prevent Manufacturer's other distributors from selling Products in the Territory, so long as such sales are not solicited in the Territory. In the event that Distributor becomes aware that other distributors of Manufacturer are selling Products in the Territory, and provides Manufacturer written notice thereof, Manufacturer will use Manufacturer's commercially reasonable efforts to limit such sales of Products. (d) CONFLICT OF INTEREST. Distributor warrants to Manufacturer that Distributor does not currently represent or promote any lines or products that compete with the Products. During the term of this Agreement, Distributor shall not, without Manufacturer's prior written consent, represent, promote or otherwise try to sell within the Territory any lines or products that, in Manufacturer's judgment, compete with the Products covered by this Agreement. (e) INDEPENDENT CONTRACTORS. The relationship of Manufacturer and Distributor established by this Agreement is that of independent contractors, and nothing contained in this Agreement shall be construed to give either party the power to direct and control the day-to-day activities of the other or allow one party to create or assume any obligation on behalf of the other for any purpose whatsoever. All financial obligations associated with Distributor's business are the sole responsibility of Distributor. All sales and other agreements between Distributor and Distributor's customers are Distributor's exclusive responsibility and shall have no effect on Distributor's obligations under this Agreement. 3. TERMS OF PURCHASE OF PRODUCTS BY DISTRIBUTOR (a) TERMS AND CONDITIONS. All purchases of Products by Distributor from Manufacturer during the term of this Agreement shall be subject to the terms and conditions of this agreement. (b) PRICES. All prices of Products are F.O.B. Manufacturer's Distribution Site at the address listed for Manufacturer at the beginning of this Agreement or as provided by written notice to Distributor. The purchase price to Distributor for each of the Products ("Purchase Price") shall be as set forth in EXHIBIT A attached hereto. The difference between Distributor's Purchase Price and Distributor's selling price to Distributor's customers shall be Distributor's sole remuneration for sale of the Products. Manufacturer has the right at any time to revise the prices in EXHIBIT A with sixty (60) days' advance written notice to Distributor; PROVIDED, that Manufacturer shall not revise such prices more than once each calendar year. Such revisions shall apply to all orders received after the effective date of revision. Price changes shall not affect unfulfilled purchase orders accepted by Manufacturer prior to the effective date of the price change. (c) TAXES. Distributor's Purchase Price does not include any federal, state or local taxes that may be applicable to the Products. In the event that such taxes are applicable and Manufacturer has the legal obligation to collect such taxes, Manufacturer shall be entitled to add to Distributor's invoice the amount of such taxes and Distributor shall pay such amount unless Distributor provides -2- Manufacturer with a valid tax exemption certificate authorized by the appropriate taxing authority. (d) ORDER AND ACCEPTANCE. All orders for Products submitted by Distributor shall be initiated by written purchase orders sent to Manufacturer and requesting a delivery date during the term of this Agreement; PROVIDED, HOWEVER, that an order may initially be placed orally or by telecopy if a confirmational written purchase order is received by Manufacturer within five (5) days after said oral or telecopy order. To facilitate Manufacturer's production scheduling, Distributor shall submit purchase orders to Manufacturer at least sixty (60) days prior to the first day of the requested month of delivery. No order shall be binding upon Manufacturer until accepted by Manufacturer in writing, and Manufacturer shall have no liability to Distributor with respect to purchase orders that are not accepted. No partial shipment of an order shall constitute the acceptance of the entire order, absent the written acceptance of such entire order. Manufacturer shall use Manufacturer's reasonable best efforts to deliver Products at the times specified either in Manufacturer's quotation or in Manufacturer's written acceptance of Distributor's purchase orders. Notwithstanding the foregoing, Manufacturer shall have no obligation to supply Products to Distributor during any period for which Distributor's payments to Manufacturer hereunder are thirty (30) days or more past due. (e) TERMS OF PURCHASE ORDERS. Distributor's purchase orders submitted to Manufacturer from time to time with respect to Products to be purchased hereunder shall be governed by the terms of this Agreement and Manufacturer's published Standard Terms and Conditions of Sale as in effect at the time of such purchase, PROVIDED that, in the event of any conflict between the terms of this Agreement and the Standard Terms and Conditions of Sale of Manufacturer then in effect, this Agreement shall be controlling. Nothing contained in any purchase order of Distributor shall in any way modify such terms of purchase of Manufacturer or add any additional terms or conditions. (f) PAYMENT. Full payment of Distributor's Purchase Price for the Products (including any freight, taxes or other applicable costs initially paid by Manufacturer but to be borne by Distributor) shall be in United States of America dollars. All exchange, interest, banking, collection, and other charges shall be at Distributor's expense. Payment terms shall be [net forty-five] ([45]) days, and payment shall be made by wire transfer, check or other instrument approved by Manufacturer. Any invoiced amount not paid when due shall be subject to a service charge at the lower of the rate of [one and one-half] percent ([1.5]%) per month or the maximum rate permitted by law. If Distributor fails to make any payment to Manufacturer when due, Manufacturer may, without affecting its rights under this Agreement, cancel or delay any future shipments of the Products to Distributor. (g) SHIPPING. All Products delivered pursuant to the terms of this Agreement shall be suitably packed for air freight shipment in Manufacturer's standard shipping cartons, marked for shipment at Manufacturer's manufacturing plant to Distributor's address set forth above, and delivered to Distributor or Distributor's carrier agent F.O.B. Manufacturer's Distribution Site, at which time title to such Products and risk of loss shall pass to Distributor. All shipments of -3- Products shall include a Certificate of Analysis for each lot. Manufacturer shall deliver Products to the carrier selected by Distributor. In the event that Distributor does not provide written notice of such carrier, Manufacturer shall select the carrier.

Distributor shall also bear all applicable taxes, duties, and similar charges that may be assessed against the Products after delivery to the carrier at Manufacturer's Distribution Site. (h) REJECTION OF PRODUCTS. Distributor shall inspect all Products promptly upon receipt thereof, such inspection to include, without limitation, a quality control analysis to determine whether Products and, where applicable, components thereof meet the specifications set forth in then-current package inserts for such Products and components and the Certificate of Analysis accompanying each shipment of Products. Distributor may reject any Product or component thereof that fails in any material way to meet such specifications. In the event that Distributor is not able to conduct a quality control analysis, Distributor, at Distributor's expense, may utilize contract facilities to conduct such analysis. Manufacturer will maintain samples of each production lot of Product, and Distributor will maintain samples of each shipment lot of Product, for archival purposes. Any Product or component thereof not properly rejected within four (4) weeks after receipt of that Product by Distributor ("Rejection Period") shall be deemed accepted. If any Product is shipped by Distributor to Distributor's customer prior to expiration of the Rejection Period, such unit shall be deemed accepted upon shipment by Distributor. To reject a Product or a component thereof, Distributor shall, within the Rejection Period, notify Manufacturer in writing or by telecopy of Distributor's rejection of such Product or component, stating the reason for such rejection. In the event that Manufacturer, in Manufacturer's sole discretion, desires that Distributor return a rejected Product or component thereof to Manufacturer, Distributor shall return to Manufacturer the rejected Product or component thereof, freight prepaid. Manufacturer will provide Distributor a credit to be applied against Distributor's future Product orders equal to the freight charges prepaid by Distributor for properly rejected Products or components thereof. As promptly as possible but no later than thirty (30) working days after receipt by Manufacturer of properly rejected Products or components thereof, Manufacturer shall replace such Products or components. Manufacturer shall pay shipping charges in connection with shipment of replaced Products or components thereof to Distributor for properly rejected Products; otherwise, Distributor shall be responsible for shipping charges. In the event that such replaced Products or components are shipped to Distributor together with Products corresponding to a purchase order pursuant to this Agreement, shipping charges in connection with such shipment shall be pro-rated between Manufacturer and Distributor.
