    of the principal amount of the Notes plus (ii) a make-whole premium
    plus (iii) accrued and unpaid interest to the redemption date. The
    make-whole premium will be calculated using a discount rate equal to
    (a) the yield on certain U.S. treasury securities (as determined at
    least two business days prior to the redemption date) plus (b) 50
    basis points.
