. We intend to use the net proceeds from the sale of the notes for the repayment of short-term borrowings, 
 which have an average annualized interest rate of approximately 4.55% and maturities under 30 days, and for general corporate purposes.                                                                                                         |

| Conflict of Interest | Certain of the underwriters or their affiliates may hold a portion of the indebtedness that we intend to repay using the net proceeds of this offering. It is possible that one or more of the underwriters or their affiliates could receive more       
 than 5% of the net proceeds of the offering, and in that case such underwriter would be deemed to have a conflict of interest under FINRA Rule 5121 (Public Offerings of Securities with Conflicts of Interest). In the event of any such conflict of    
 interest, such underwriter would be required to conduct the distribution of the notes in accordance with FINRA Rule 5121. If the distribution is conducted in accordance with FINRA Rule 5121, such underwriter would not be permitted to confirm a sale 
 to an account over which it exercises discretionary authority without first receiving specific written approval from the account holder. See “Underwriting — Conflict of Interest” herein.                                                               |
