Accordingly, there follows the mutual understanding between IMMU and LILLY as to the terms and conditions applicable to this Agreement. NOW IT IS HEREBY AGREED AS FOLLOWS: 1. Import of the Product into the European Union 1.1 The Product is manufactured in the United States of America. IMMU warrants that the Product has the necessary regulatory 1 and legal approvals for the export thereof out of the US with import, sale, and distribution to countries in the European Union and any other country in which the Product shall be sold. IMMU has the responsibility to maintain these approvals. If for whatever reason, LILLY is required to receive regulatory and legal approvals for the Product for the activities covered in this Agreement, IMMU will provide LILLY with the information necessary to secure such approvals. 1.2 The port of arrival of the Product is LILLY, Giessen, Germany. 1.3 IMMU shall arrange for transport of the Product (contained in glass vials) to the port of arrival in accordance with the relevant instructions given by LILLY with respect to the addressing of the shipment, proper labeling in accordance with international regulations, and the contents of the necessary documentation. Cost for transport and insurance fees covering damage and loss of the Product to the port of arrival shall be for the account of IMMU. 1.4 Product delivered to LILLY by IMMU hereunder for storage, labeling, packaging and distribution will remain at all times under and subject to the ownership, direction and control of IMMU until sold to the end users. Title to the Product distributed by LILLY will pass directly from IMMU to the end users who purchase the Product from IMMU. IMMU shall bear the risk of loss of the Product not yet delivered by LILLY to a customer, whether by fire, theft, or other casualty; provided, however, that LILLY shall promptly reimburse IMMU [*] for each 2 vial of the Product which is lost or damaged as a result of LILLY's negligence. 1.5 LILLY shall take all reasonable steps to clear the Product through Customs. All clearance fees and levied import duties and taxes, if charged to LILLY as importer of the Product, are for the account of IMMU and will be reimbursed by IMMU upon LILLY's presentation of the corresponding invoices and/or charge notes. 2. Quality Control of the Product 2.1 IMMU warrants to LILLY that each lot of Product imported into the European Union (and into those countries outside of the European Union to which IMMU requests LILLY to deliver the Product) shall satisfy, at the time of importation, all quality criteria set forth in its Summary of Product Characteristics. Promptly following arrival of each shipment of the Product, LILLY shall conduct all necessary quality control inspections, according to procedures and specifications agreed with IMMU, including without limitation, labeling, documentation, visual inspection of each lot of the Product for external container or other damage or loss, and inspection of the temperature recorder data accompanying such shipment to determine that the Product was not exposed to temperatures outside of the acceptable range defined by IMMU during the transport thereof to the port of arrival. LILLY shall report any such damage or loss to IMMU promptly. IMMU 3 will promptly notify LILLY of any change made in quality criteria and in quality control procedures and specifications which is relevant to the activities and services provided by LILLY pursuant to this Agreement. 2.2 IMMU warrants to LILLY that the packing and storage conditions required for the Product, either in transit or during warehouse storage, are such that the Product will continue to satisfy all quality specifications as defined in the Summary of Product Characteristics during the entire period of storage until a predetermined expiration date, provided LILLY stores and ships the Product in accordance with approved procedures. 2.3 To enable LILLY to perform its packaging and distribution function for the Product, IMMU shall provide LILLY with those details relating to the Product as are required by the European Union or applicable national regulations. If required by competent authorities, IMMU shall authorize qualified LILLY representatives (Manufacturing and/or Quality Control) (collectively, "LILLY Representatives") to inspect the Product facility and its operational procedures. This inspection does not imply that IMMU has any obligation to reveal its trade secrets with respect to the essential steps of manufacturing the Product. IMMU shall provide LILLY with all information relevant to the release of each lot of Product, including (but not limited to) the relevant Certificate of Analysis for the Product provided by a European Union-qualified laboratory. LILLY grants the right to IMMU to 4 inspect LILLY's labeling, packaging, storage and shipping facilities. 2.4 IMMU shall perform or shall have performed on all lots of Product imported, all relevant tests required by European Union regulations, or by the applicable national law of countries outside the European Union. Such tests as IMMU is unable to perform itself will be executed by a qualified third party laboratory within the European Union. No lot of Product shall be shipped by IMMU to LILLY until the third party laboratory shall have certified that the sample batch therefrom shall have satisfied all required tests. 2.5 IMMU will indicate clearly in all its correspondence, documents and product labels the item number, product name, lot number(s), manufacturing date(s) and expiry date(s) of each shipment of Product. 2.6 Any information IMMU possesses or receives which casts doubt on the usability of the Product, or a specific lot of the Product, shall be promptly shared with an authorized representative of LILLY and in consultation between IMMU and LILLY all the necessary decisions and steps will be made and taken to control further distribution of the Product or specific lot of the Product in question. LILLY will provide IMMU with all necessary information and support to perform a recall, if required. The final decision as to whether a recall is required, and notification to end users, is the responsibility of IMMU. All costs associated with such 5 actions shall be for the account of IMMU, unless such defect shall be due to the fault or negligence of LILLY in performing its obligations under this Agreement, in which event such costs shall be borne by LILLY. The recalled and returned Product shall be kept available to IMMU to be treated in the way IMMU deems fit. IMMU cannot direct return of whatever number of vials of the recalled material LILLY is required by applicable law to retain. 2.7 LILLY Representatives will release the finished lots according to current LILLY procedures and based on (but not limited to) the relevant Certificate of Analysis provided by the authorized European Union-qualified laboratory. If a deviation which might affect the quality of the Product occurs, LILLY will consult with IMMU for finished lot approval. 2.8 IMMU shall provide LILLY with all necessary information about the Product, including but not limited to, safety data, in order to enable the appropriate and safe handling of the Product by LILLY. 3.

When an agreed minimum level of stock is reached, LILLY will inform IMMU accordingly, and IMMU will take all necessary action to replenish the stock to a level deemed appropriate by IMMU. 3.5 LILLY will distribute Product with the earliest expiry date first, unless otherwise directed by IMMU. No delivery to end users will take place after the expiration date of any lot of Product or after any date prior to that expiration date determined by IMMU and communicated to LILLY in writing. 3.6 IMMU will be responsible for directing end users regarding return of the Product. Product for whatever reason returned 7 will not be returned to saleable inventory unless agreed to by IMMU and promptly communicated to LILLY.

IMMU will reimburse LILLY for the costs associated with this disposition. 3.7 LILLY will timely and regularly advise IMMU of the number of vials of the Product and their respective lot numbers of any expired Product and shall keep such Product at IMMU's disposal until one month after its expiration date. After that date, unless IMMU advises LILLY that it expects to be able to extend the expiration date, IMMU shall determine the manner of disposition of such expired Product, which shall be at the expense of IMMU. 3.8 LILLY will hold the necessary resources available for inspections by the competent authorities of its premises and procedures relating to the Product. LILLY will assist in a manner consistent with practices in the industry to obtain satisfactory results of such inspections. 4. Package Development and Packaging of the Product 4.1 LILLY will manage the development of packaging materials (including labels and package leaflets) with IMMU. IMMU will provide LILLY with an approved packaging file for each packaging presentation that LILLY will be responsible for managing. LILLY will develop and coordinate the creation of packaging materials according to these approved files. 8 LILLY bears the responsibility for any inconsistencies in packaging materials vis-a-vis the approved packaging files. LILLY will provide specimens of packaging materials to IMMU promptly upon preparation. 4.2 LILLY shall maintain a sufficient inventory of labelling/packaging materials. 4.3 IMMU will communicate to LILLY changes to the approved packaging in a timely manner and provide an update to the approved packaging file for each packaging presentation which is changed.

The Service Fee shall consist of a Product Packaging Fee (which shall be LILLY's compensation for all services rendered and materials required in connection with the importation, storage, inventory management, labeling and packaging of the Product) and a Shipment Fee (which shall be LILLY's compensation for all services rendered and materials required in connection with the filling and shipment of each order of the Product (including invoicing thereof) to the end user). 9.3 The Product Packaging Fee shall be based on the total number of vials of the Product labeled and packaged annually by LILLY pursuant to orders transmitted by IMMU to LILLY therefor. For the first [*] vials labeled and packaged in a twelve month period, the Product Packaging Fee shall be [*] per vial. For the next [*] vials labeled and packaged in that twelve month period, the Product Packaging Fee shall be [*] per vial.

(b) Promptly following the end of the twelfth month of distribution of the Product by LILLY, and following the end of each twelve month period thereafter, the parties shall calculate the amount of the Product Packaging Fee and the Shipment Fee actually due as provided in Sections 9.3 and 9.4 in respect of such services rendered during the twelve months then ended. If the amount of the Service Fee thus calculated exceeds the aggregate Monthly Service Fee payments previously 15 made or deemed made ([*] in the first year), IMMU shall remit the amount of such excess to LILLY within 30 days of receiving LILLY's invoice therefor. (c) The parties agree that following the initial calculation under paragraph (b) above, and at the end of each annual period thereafter, they will reevaluate the fairness and adequacy of the Monthly Service Fee, the Product Packaging Fee and the Shipment Fee with a view to making such adjustments thereto as shall be mutually acceptable. 10. Addition of CEA-Scan(R) as a Product; Other Products 10.1 At the request of IMMU, Lilly shall also provide all of the services required of it hereunder for the importation, storage, labeling, packaging and distribution of CEA-Scan(R), an additional product of IMMU, and the term "Product" shall then include both LeukoScan(R) and CEA-Scan(R). In such event, the Product Packaging Fee computation to be made under Section 9.3 shall include the total number of vials of LeukoScan(R) and CEA- Scan(R), taken together, labeled and packaged by Lilly.
