NOTE 3. COLLABORATION AGREEMENT

(a) Collaboration Agreement with Astellas

In October 2009, the Company entered into the Astellas Collaboration Agreement, pursuant to which it is collaborating with Astellas to develop and commercialize XTANDI globally for all indications, dosages and formulations of enzalutamide. Under the agreement, decision making and economic participation differs between the U.S. market and the ex-U.S. market. In the United States, decisions are generally made by consensus, pre-tax profits and losses are shared equally, and, subject to certain exceptions, development and commercialization costs (including cost of goods sold and the royalty on net sales payable to UCLA under the Company’s license agreement with UCLA) are also shared equally. The primary exceptions to equal cost sharing in the U.S. market are that each party is responsible for its own commercial full-time equivalent, or FTE, costs, and that development costs supporting marketing approvals in both the United States and either Europe or Japan are borne one-third by the Company and two-thirds by Astellas. The Company and Astellas are co-promoting XTANDI in the U.S. market, with each company providing half of the sales and medical affairs effort in support of the product. Both the Company and Astellas are entitled to receive a fee for each qualifying detail made by its respective sales representatives. Outside the United States, decisions are generally made by Astellas and all development and commercialization costs (including cost of goods sold and the royalty on net sales payable to UCLA) are borne by Astellas. Astellas retains all ex-U.S. profits and losses, and pays the Company a tiered royalty ranging from the low teens to the low twenties as a percentage of the aggregate net sales of XTANDI outside the United States, or ex-U.S. XTANDI net sales. Astellas has sole responsibility for promoting XTANDI outside the United States and for recording all XTANDI net sales both inside and outside the United States. Both the Company and Astellas have agreed not to commercialize certain other products having a similar mechanism of action (as defined by the Astellas Collaboration Agreement) as XTANDI for the treatment of prostate cancer for a specified time period, subject to certain exceptions.

Under the Astellas Collaboration Agreement, Astellas paid the Company a non-refundable, upfront cash payment of $110.0 million in the fourth quarter of 2009. The Company was also eligible to receive up to $335.0 million in development milestone payments and up to $320.0 million in sales milestone payments. As of December 31, 2015, the Company has earned all development and sales milestone payments under the Astellas Collaboration Agreement.

The Company and Astellas are each permitted to terminate the Astellas Collaboration Agreement for an uncured material breach by the other party or for the insolvency of the other party. Astellas has a right to terminate the Astellas Collaboration Agreement unilaterally by advance written notice to the Company. Following any termination of the Astellas Collaboration Agreement in its entirety, all rights to develop and commercialize XTANDI will revert to the Company, and Astellas will grant a license to the Company to enable it to continue such development and commercialization. In addition, except in the case of a termination by Astellas for the Company’s material breach, Astellas will supply XTANDI to the Company during a specified transition period.

Unless terminated earlier by the Company or Astellas pursuant to the terms thereof, the Astellas Collaboration Agreement will remain in effect: (a) in the United States, until such time as Astellas notifies the Company that Astellas has permanently stopped selling products covered by the Astellas Collaboration Agreement in the United States; and (b) in each other country of the world, on a country-by-country basis, until such time as (i) products covered by the Astellas Collaboration Agreement cease to be protected by patents or regulatory exclusivity in such country and (ii) commercial sales of generic equivalent products have commenced in such country.
