Exercise/Distribution of Option/Award Shares
The exercised option shares may be paid in one of three ways: by cash; or by a “stock swap” or by the “net share issuance”. For a stock swap, the grantee would tender already owned Common Stock or Class A Common Stock as all or part of the aggregate option purchase price valued at the closing price on the date of exercise as reported by the Wall Street Journal. A net share issuance is similar to a stock swap in that an amount of shares equal to the exercise and withholding tax is netted against the gross amount of shares exercised. Only the amount of shares remaining after such deductions is given to the grantee.
The restricted stock award shares are distributed on the vesting dates according to the vesting schedule. No consideration is due from the employee other than employment at Molex or any of its subsidiaries and affiliates at the time of distribution.
