(1) On September 19, 2014, the Reporting Person was granted a performance-based stock option to purchase 1,125,000 shares of common stock pursuant to the Exelixis, Inc. 2014 Equity Incentive Plan. Vesting of the option is tied to performance goals set by the Compensation Committee (the "Committee") as follows: (i) 50% of the option will vest if the Committee determines that top-line efficacy data received from the METEOR phase 3 pivotal trial of cabozantinib in metastatic renal cell carcinoma ("mRCC") met its primary endpoint at a specified level, with such result to occur no later than a specified date; (ii) 25% of the option will vest if the Committee confirms that a new drug application ("NDA") for cabozantinib for the treatment of mRCC is accepted for review by the United States Food and Drug Administration ("FDA") by a specified date; and (iii) 25% of the option will vest if the Committee confirms that the FDA has approved cabozantinib for the treatment of mRCC by a specified date.
(2) On April 28, 2016, the Committee convened to determine that the NDA for cabozantinib for the treatment of mRCC was approved by the FDA within the time period permitted by the performance goals, resulting in the vesting of the option as to the remaining 281,250 shares.
(3) On February 5, 2015, the Reporting Person was granted a performance-based stock option to purchase 450,000 shares of common stock pursuant to the Exelixis, Inc. 2014 Equity Incentive Plan. Vesting of the option is tied to performance goals set by the Committee as follows: (i) 50% of the option will vest if the Committee determines that top-line efficacy data received from the METEOR phase 3 pivotal trial of cabozantinib in mRCC met its primary endpoint at a specified level, with such result to occur no later than a specified date; (ii) 25% of the option will vest if the Committee confirms that an NDA for cabozantinib for the treatment of mRCC is accepted for review by the FDA by a specified date; and (iii) 25% of the option will vest if the Committee confirms that the FDA has approved cabozantinib for the treatment of mRCC by a specified date.
(4) On April 28, 2016, the Committee convened to determine that the NDA for cabozantinib for the treatment of mRCC was approved by the FDA within the time period permitted by the performance goals, resulting in the vesting of the option as to the remaining 112,500 shares.
