Manner of Exercising Option Shares. A Participant who desires to exercise an Option and to defer current receipt and distribution of the gain related to Gain Shares must follow the procedures and requirements that are applicable to the Option under the Pitney Bowes Stock Plan as amended and restated, January 1, 2002, including the procedures and requirements relating to the exercise of an Option; provided, however, that in the case of a deferral of Gain Shares under this Plan, the Participant shall only be permitted to tender Consideration Shares to pay the entire exercise price for any exercised Option. Notwithstanding the foregoing, the Administrative Committee may in its discretion accept the Participants attestation that he or she owns the number of Consideration Shares necessary to effectuate the stock swap contemplated hereunder. The attestation method or any other procedure accepted by the Administrative Committee shall be consistent with applicable legal authority regarding the tax-free treatment of such a transaction.
