Par Call Date).

Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the

principal of and interest on the Securities that would be due after the related redemption date but for the redemption (but not including any interest accrued as of the date of redemption). If that redemption date is not an interest payment date

Notice of redemption will be mailed at least 10 days but not more than 60 days before the redemption date to each Holder of Securities to be
redeemed at its registered address. Securities in denominations larger than $2,000 may be redeemed in part. On and after the redemption date interest ceases to accrue on Securities or portions of them called for redemption, provided that if
