 (for any series of RSNs that the Company elects to remarket as fixed-rate notes) and the reset spread (for any series of RSNs that the Company elects to remarket as floating-rate notes) will be the interest rate or spread determined by the remarketing agent, in consultation with the Company, as the rate or spread, as the case may be, that each series of RSNs should bear in order for the remarketing proceeds to equal at least 100% of the principal amount of the RSNs being remarketed. In any case, the reset rate (for any series of RSNs remarketed as fixed-rate notes) or the applicable interest rate index plus the reset spread (for any series of RSNs remarketed as floating-rate notes), as applicable, may be higher or lower than the initial interest rate on such series of RSNs depending on the results of the remarketing and market conditions at that time. However, in no event will the reset rate or the applicable interest rate index plus the reset spread, as the case may be, exceed the maximum rate permitted by applicable law. In addition, following a successful remarketing, interest on any series of RSNs remarketed as fixed-rate notes will be payable on a semi-annual basis on June 15 and December 15 of each year.
