The resulting fraction shall then be multiplied by 1,000,000 Shares to determine each Eligible Employee's number of Option Shares; provided, however, that the total shall be rounded down to the nearest whole Share. An Eligible Employee who is granted an Option pursuant to this Section 5.1(c) shall not be eligible to be granted an Option under Section 5.1(d).
