The Corporation shall pay to the Executive, in cash, in a lump sum, on the Payment Date an amount equal to two and one half (2.5) times the annual allowance to which the Executive is entitled as of the date of the Date of Termination (or, if higher, as of immediately prior to the Effective Date).

Professional Membership Fees. The Corporation shall pay the Executive, in cash, in a lump sum, on the Payment Date, an after-tax amount equal to two and one half (2.5) times the amount reimbursed or paid by the Corporation (separate from the annual allowance) in respect of membership fees for membership in professional organizations related to the Executive’s position and duties with the Corporation for the year preceding the year in which the Date of Termination occurs (or, if greater, preceding the year in which the Effective Date occurs).

IN WITNESS WHEREOF this Second Amendment has been executed effective as of the Effective Date.
