Stock options granted pursuant to an Election Grant shall be for a number of whole shares of Common Stock. Any fractional share of Common Stock shall be rounded down to the nearest whole share of Common Stock. Fractions of shares of Common Stock subject to a stock option shall not vest on a vesting date of an Initial Grant, an Annual Grant, an Interim Annual Grant, or an Election Grant, and the shares of Common Stock that do vest on a vesting date shall be rounded down to the nearest whole share of Common Stock; provided, however, that such fractions of shares of Common Stock shall be added to the number of shares of Common Stock that vest on the final vesting date or that otherwise vest due to the vesting acceleration (with any resulting fraction of a share of Common Stock being rounded down to the nearest whole share of Common Stock).
