 2032 fixed rate notes. The underwriters may allow, and the dealers may reallow, a discount on the notes to other dealers not in excess of 0.050% of the principal amount of the 2027 floating rate notes, 0.100% of the principal amount of the 2028 floating rate notes, 0.050% of the principal amount of the 2027 fixed rate notes, 0.100% of the principal amount of the 2028 fixed rate notes and 0.125% of the principal amount of the 2032 fixed rate notes. After the initial offering, the underwriters may change the public offering price, concession or any other term of the offering. We estimate that our total expenses (which consist of, among other fees, SEC registration fees, legal fees and expenses, accounting fees and expenses and printing expenses) for this offering will be approximately $3,000,000. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make because of any of those liabilities. Price Stabilization and Short Positions In connection with the offering, the underwriters may purchase and sell the notes in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and S-43

stabilizing purchases. Short sales involve sales by the underwriters of a greater principal amount of notes than they are required to purchase in the offering. The underwriters must close out any
short position by purchasing notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the prices of the notes in the open market after pricing that could
adversely affect investors who purchase in the offering. Stabilizing transactions involve bids to purchase notes so long as the stabilizing bids do not exceed a specified maximum.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales, stabilizing purchases, as well
as other purchases by the underwriters’ for their own accounts, may have the effect of raising or maintaining the market prices of the notes or preventing or retarding a decline in the market prices of the notes. As a result, the prices of the
notes may be higher than the prices that might otherwise exist on the open market.

Neither we nor any of the underwriters make any
representation
