Except for Notes sold to level-fee accounts, Notes offered to the public will be offered at the public offering price set forth in this Pricing Supplement. Selected dealers purchasing Notes on an agency basis for non-level fee client accounts shall purchase Notes at the public offering price. Notes purchased by the selected dealers for their own account may be purchased at the public offering price less the applicable concession. Notes purchased by the selected dealers on behalf of level-fee accounts may be sold to such accounts at the applicable concession to the public offering price, in which case, such selected dealers will not retain any portion of the sales price as compensation.

 

If the maturity date or an interest payment date for any note is not a business day (as term is defined in prospectus), principal, premium, if any, and interest for that note is paid on the next business day, and no interest will accrue from, and after, the maturity date or interest payment date.
