This MOU replaces and supercedes in its entirety the MOU between AltaRex and Dompe dated November 10, 2000. The purpose of this MOU is to set forth the mutual understanding of AltaRex and Dompe (the "Parties") regarding the terms of a Collaboration and Distribution Agreement between the two companies by which Dompe will act as exclusive distributor for AltaRex's OvaRex(TM) MAb (the "Product") in Italy, Switzerland, Austria, Spain, Portugal, the Republic of San Marino, the State of the Vatican City and certain Eastern European countries (Ukraine, Belarus, Hungary, Poland, Czech Republic, Yugoslavia, Lithuania, Estonia and Latvia) (the "Territory") as well as provisions for investments in Common Shares of AltaRex. The Parties will further enter into discussions regarding the possible inclusion of Russia into the Territory for a period not to exceed 120 days from the date of the signing of this MOU, during which period AltaRex will not discuss with others the licensure of Product for Russia. This MOU is a binding commitment with respect to the investment provisions as outlined in Section 9. Further, this MOU is intended to provide a general framework for a more detailed Distribution Agreement (the "Agreement"). The Parties agree to work together in good faith in order to complete such an Agreement within 90 days of signing of this MOU. 1. DISTRIBUTION AGREEMENT AltaRex hereby grants Dompe exclusive distribution rights for the Product in the Territory. AltaRex also grants to Dompe a Right of First Offer ("ROFO") for the Territory to enter into negotiation over a ninety day period on each additional antibody for cancer ("Other Products") when each antibody enters Phase II clinical trials in the United States or Europe. At the moment, Other Products refer to BrevaRex(R), AR54, ProstaRex(TM) and GivaRex(TM) antibodies. Pursuant to this agreement between Dompe and AltaRex, Dompe will commercialize the Product either directly or indirectly in the Territory. Dompe shall also be responsible for obtaining pricing authorization from the Italian authorities and shall make reasonable efforts to obtain a price consistent with other worldwide pricing policies and practices for the Product at the time regulatory approval is obtained by AltaRex. In establishing a price in Italy, Dompe shall advise AltaRex and its other partners of its discussions with Italian authorities. 2. CLINICAL DEVELOPMENT Upon the availability of cell culture-produced OvaRex(TM) MAb, AltaRex will supply, [**] to Dompe, sufficient OvaRex(TM) MAb for a [**] patient trial of the Product to be conducted in the Territory. Such trial (either as a separate trial or as part of a multicenter, multinational trial) shall be conducted by Dompe using a protocol supplied by AltaRex and agreed upon by the Parties. Confidential Page 2 11/15/00 Any and all other costs for such trial will be borne exclusively by Dompe. The data resulting from such trial, and any other pertinent information thereto, will be the property of AltaRex. Dompe shall be given access to clinical and other data available to AltaRex and its other licensees and other resellers, to the extent such data may be useful in order to obtain required pricing approval in the Territory and for marketing purposes. 3. TERM OF THE AGREEMENT The initial term of the Agreement shall be ten (10) years starting from the commercialization date of the Product. Thereafter, the Agreement will provide for automatic 24 month renewals (each 24 month renewal an "Extension Term") unless either Party gives the other written notice of its intention not to renew the Agreement, provided that either Party gives notice of its intention not later than 24 months prior to the expiration of the initial term or not later than 12 months prior to the expiration of any Extension Period. 4. ORDERING AND FORECASTING Upon the granting or marketing authorization in the Territory, Dompe shall submit to AltaRex a forecast containing the unit volume of Product to be ordered over the following 12 months for each country of the Territory. This forecast will be updated quarterly and provided to AltaRex within 10 working days of the beginning of each quarter. Irrevocable purchase orders for the Product shall be placed not less than 3 months in advance of the required delivery date. 5. PURCHASE MINIMUM During each year of the Agreement, Dompe agrees to purchase a designated number of units ("Purchase Minimum") of the Product. The Purchase Minimum shall be based on the registration of the Product by the Ministry of Health ("MOH") as either a Class A drug (no prescribing limitations) or Class H drug (prescribing limitations). If the Product is registered as a Class B or Class C drug, the Parties shall negotiate in good faith a revised Purchase Minimum. During contract years 1 through 3 the Purchase Minimum shall equal [**]% of the amount set forth in a schedule to be defined by the Parties and attached to the final Agreement as Appendix A. 6. REGULATORY APPROVAL AltaRex at its own cost will be responsible for obtaining marketing authorization in the Territory. Dompe shall furnish assistance to AltaRex in its efforts to obtain marketing approval from the MOH. AltaRex and Dompe shall cooperate fully with each other in submitting and prosecuting such applications including a co-ordinated approach with Dompe for achieving an accelerated approval in Italy. 7. PURCHASE PRICE AltaRex will sell each unit of Product to Dompe for an amount equal to [**] percent ([**]%) of the ex-factory reimbursed price for the Product established by applicable government authorities Confidential Page 3 11/15/00 in each market. If the ex-factory reimbursement price is lower than the expected $[**] by an amount exceeding 10%, the Parties will negotiate an appropriate solution in good faith. If, AltaRex has accepted a lower price in any European Economic Community (EEC) country, Dompe will be able to commercialize the Product in the Territory at that lower ex-factory reimbursement price. 8. MILESTONE PAYMENTS Dompe agrees to pay to AltaRex U.S. $1.0 million upon the first commercialization (marketing approval and reimbursement without restriction for either the "watchful waiting" or the recurrent disease indication) of OvaRex(TM) MAb in Spain and U.S. $0.250 million upon a similar commercialization approval and reimbursement in Portugal. 9.
