 prospectus is a part. When we refer to the “indenture”
in this prospectus, we are referring to the indenture under which the debt securities are issued as supplemented by any supplemental indenture
applicable to the debt securities. We will provide the name of the trustee in any prospectus supplement related to the issuance of debt
securities, and we will also provide certain other information related to the trustee, including describing any relationship we have with
the trustee, in such prospectus supplement.

THE FOLLOWING DESCRIPTION IS A SUMMARY OF THE
MATERIAL PROVISIONS OF THE INDENTURE. IT DOES NOT RESTATE THE INDENTURE IN ITS ENTIRETY. THE INDENTURE IS GOVERNED BY THE TRUST INDENTURE
ACT OF 1939. THE TERMS OF THE DEBT SECURITIES INCLUDE THOSE STATED IN THE INDENTURE AND THOSE MADE PART OF THE INDENTURE BY REFERENCE
TO THE TRUST INDENTURE ACT. WE URGE YOU TO READ THE INDENTURE BECAUSE IT, AND NOT THIS DESCRIPTION, DEFINES YOUR RIGHTS AS A HOLDER OF
THE DEBT SECURITIES.

Information You Will Find in the Prospectus Supplement

The indenture provides that we may issue debt
securities from time to time in one or more series and that we may denominate the debt securities and make them payable in foreign currencies.
The indenture does not limit the aggregate principal amount of debt securities that can be issued thereunder. The prospectus supplement
for a series of debt securities will provide information relating to the terms of the series of debt securities being offered, which may
include:

| ● | the title and denominations of the debt securities of the series; |

| ● | any limit on the aggregate principal amount of the debt securities of the series; |

| ● | the date or dates on which the principal and premium, if any, with respect to the debt securities of the series are payable or the 
 method of determination thereof;                                                                                                   |

| ● | the rate or rates, which may be fixed or variable, at which the debt securities of the series shall bear interest, if any, or the 
 method of calculating and/or resetting such rate or rates of interest;                                                            |

| ● | the dates from which such interest shall accrue or the method by which such dates shall be determined and the duration of the extensions 
 and the basis upon which interest shall be calculated;                                                                                   |
