 securities the United States Treasury security that is trading closest to
par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity
of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to
three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all
purposes, absent manifest error. Neither the Trustee nor the calculation agent shall be responsible for or have any responsibility to determine or make any calculations in connection with any redemption.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC’s procedures) to
each holder of senior notes to be redeemed (with a copy to the Trustee) at least 5 days but not more than 60 days before the redemption date. Unless we default in payment of the redemption price, on and after the redemption date interest will cease
to accrue on the senior notes or portions thereof called for redemption.

In the case of a partial redemption, selection of the senior
notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair; provided that, for so long as the senior notes are held by DTC (or another depositary), any redemption of
the senior notes shall be effected in accordance with the policies and procedures of the depositary.

The senior notes may not otherwise
be redeemed prior to the senior notes maturity date.
