(3) Each restricted stock unit represents a contingent right to receive one share of Old Merck common stock and was (i) assumed by the Surviving Corporation in the Transactions and (ii) converted into a restricted stock unit representing a contingent right to receive one share of Surviving Corporation Common Stock on the same vesting schedule as applied prior to the Transactions.
(4) This option to purchase shares of Old Merck common stock, which vesting in three equal annual installments beginning one year from date of grant, was assumed by the Surviving Corporation in the Transactions and continued on the same terms and conditions as an option to purchase an equivalent number of shares of Surviving Corporation Common Stock at the same exercise price as applied prior to the Transactions.
(5) This option to purchase shares of Old Merck common stock, which vesting on the exercisable date, was assumed by the Surviving Corporation in the Transactions and continued on the same terms and conditions as an option to purchase an equivalent number of shares of Surviving Corporation Common Stock at the same exercise price as applied prior to the Transactions.
