That award no longer represents the right to receive shares of the issuer's common stock. Instead, if the applicable performance goal is achieved by December 31, 2016, the reporting person will be entitled to the grant of a stock option with respect to the same number of shares that would have been issued to the reporting person upon achievement of the goal under the original terms of the award. The option is scheduled to vest in eight semi-annual installments over the four-year period following the grant date, subject to the reporting person's continued employment or service with the issuer through the applicable vesting date.
