Following any successful remarketing of the RSNs:

• the interest rate on each series of RSNs may be reset as described below and under “Description of the Remarketable Senior Notes—Interest Rate Reset” below;

• interest will be payable on the RSNs semi-annually on June 15 and December 15 of each year (except with respect to any series of RSNs remarketed as floating-rate notes); and

• the Series 2025C RSNs will cease to be redeemable at the Company’s option, and the provisions described under “Description of the Remarketable Senior Notes—Redemption at the Company’s Option” and “—Redemption Procedures” will no longer apply to the Series 2025C RSNs.

All such modifications will take effect only if the remarketing is successful, without the consent of holders, upon the earlier of the optional remarketing settlement date or the purchase contract settlement date, as the case may be, and will apply to all RSNs of such series, whether or not included in the remarketing. All other terms of the RSNs will remain unchanged.

In order to remarket the RSNs, the remarketing agent, in consultation with the Company, may:

• remarket each series of RSNs as fixed-rate notes or floating-rate notes;

• in the case of any series of RSNs remarketed as fixed-rate notes, reset the interest rate on such series of RSNs (either upward or downward) and, in the case of any series of RSNs remarketed as floating-rate notes, determine the interest rate spread applicable to such series of RSNs, in order to produce the required price in the remarketing, as discussed under “—Optional Remarketing” and “—Final Remarketing” below; and

• in the case of any series of RSNs remarketed as floating-rate notes, (i) provide that the interest on such series of RSNs will be equal to an interest rate index determined by the Company plus a spread determined by the remarketing agent, in consultation with the Company, in which case interest on such series of RSNs may be calculated on the basis of a 360-day year and the actual number of days elapsed (or such other basis as is customarily used for floating-rate notes bearing interest at a rate based on such interest rate index), and (ii) provide for provisions regarding calculation of the selected
