 set forth on the cover page of this prospectus supplement and in part to certain securities dealers at such price less a concession not in excess of 0.250% of the principal amount of the Notes. The underwriters may allow, and such dealers may reallow, a concession not to exceed 0.150% of the principal amount of the Notes to certain brokers and dealers. After the initial public offering, the public offering price, concession and discount may be changed. In addition, HSI and/or its affiliates will reimburse us for certain of our offering related expenses and underwriting discounts and commissions. Certain of the underwriters may not be U.S. registered broker-dealers and accordingly will not effect any offers or sales of any Notes in the United States unless it is through one or more U.S. registered broker-dealers as permitted by applicable securities laws and the regulations of FINRA. The underwriting agreement provides that the obligations of the underwriters to purchase the Notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters have S-58

agreed to purchase all of the Notes sold pursuant to the underwriting agreement if any of the Notes are sold. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaultingunderwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the several underwriters against certain liabilities, including civil liabilities under the Securities Act, or contribute to payments the underwriters may be required to make in respect thereof. It is expected that the delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which is the sixth business day following the date hereof (this settlement cycle being referred to as T+6). Under Rule 15c6-1under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to the trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to one business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+6, to specify an alternative settlement cycle at the time of any trade to prevent a failed settlement and should consult their own adviser. The following are the estimated expenses to be incurred in connection with the issuance and distribution of the Notes:

| SEC registration fee                                                |     | $ | 229,650 |
| Printing expenses                                                   |     | $ |
