Section 1.4 Terms and Provisions of Notes. The Notes shall be governed by all of the terms and provisions of the Original Indenture, as supplemented by this Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes:

(a) Registration and Form. The Notes shall be issuable as registered securities as provided in Section 1.3 of this Supplemental Indenture. The Notes shall be issued and may be transferred only in minimum denominations of $2,000 and integral multiples of 1,000 in excess thereof.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Interest on the Notes shall accrue from August 10, 2021.

(c) Sinking Fund, Redemption or Repayment. No sinking fund shall be provided for the Notes and the Notes shall not be repayable at the option of the Holders thereof prior to Stated Maturity.

(d) Redemption at the Option of the Issuer.

(1) Prior to June 1, 2031 (the “Par Call Date”), the Notes will be redeemable at any time in whole, or from time to time in part, at the option of the Issuer on any date at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed, and (ii) the sum of the present values as of the date of redemption payment of the remaining scheduled payments of principal of and interest on the Notes to be redeemed, after the date of redemption payment through the Par Call Date (assuming, for this purpose, that the Notes are scheduled to mature on the Par Call Date) (the “Assumed Remaining Life”) (exclusive of interest accrued to the applicable redemption date) discounted to such redemption date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points, plus, in the case of both clauses (i) and (ii) above, any accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding, such Redemption Date. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on an Interest Payment Date falling on or prior to the relevant Redemption Date will be payable to the persons who were the Holders of the Notes registered as such at the close of business on the relevant Regular Record Dates according to the terms and provisions of the Indenture. If the Notes are redeemed on or after the Par Call Date, the redemption price will be equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

(2) Notice of any redemption by the Issuer will be mailed at least 15 days but no more than 60 days before the Redemption Date to each Holder of Notes to be redeemed. The notice of redemption will specify among other things, the Redemption Price and principal amount of the Notes held by the Holder to be redeemed.

(3) The notice of redemption may contain any conditions that must be satisfied before such redemption will occur.

(4) If the Issuer chooses to redeem less than all of the Notes of a series, the Issuer will notify the Trustee at least 20 days prior to the Redemption Date, or a shorter period as may be satisfactory to the Trustee, of the aggregate principal amount of Notes of the series to be redeemed, if less than all of the Notes of that series are to be redeemed, and their Redemption Date. The Trustee will select, based on a method that most nearly approximates a pro rata selection unless otherwise required by law or applicable stock exchange or depositary requirements, no less than 15 days nor more than 60 days prior to the Redemption Date, the Notes of that series to be redeemed in whole or in part.

4

(5) Unless the Issuer defaults in payment of the Redemption Price, on and after any Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

(e) Defeasance: Covenant Defeasance; Waiver. The provisions for defeasance in Section 402(2) of the Original Indenture for covenant defeasance in Sections 402(3) and 1012 of the Original Indenture shall apply to the Notes (including, without limitation, to the covenants set forth in Article Two hereof and Article Ten of the Original Indenture as if such covenants were referred to therein).

(f) Further Issues. The Issuer may, from time to time, without the consent of the Holders, create and issue further securities having the same terms and conditions as the Notes in all respects, except for issue date and issue price. Additional Notes issued in this manner shall be consolidated with and shall form a single series with the previously outstanding Notes. Notice of any such issuance shall be given to the Trustee and a new supplemental indenture or amendment to this Supplemental Indenture shall be executed in connection with the issuance of such securities.

(e) Events of Default. The provisions of Section 501 of the Original Indenture shall be replaced in their entirety by the following with respect to the Notes:

“Event of Default” whenever used herein with respect to the Notes means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or to be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) default in the payment of any installment of interest on any Note when such interest becomes due and payable, and continuance of such default for a period of 30 days; or

(2) default in the payment of the principal of or any premium on any Note when it becomes due and payable at the Final Maturity Date; or

(3) default in the performance, or breach, of any covenant or warranty of the Issuer in the Indenture or the Notes (other than a covenant or warranty a default in the performance or the breach of which is elsewhere in this Section 1.4(e) specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in the principal amount of the outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(4) default under any evidence of recourse Indebtedness of the Issuer or the Company, or under any mortgage, indenture or other instrument of the Issuer or the Company (including a default with respect to Securities of any series other than the Notes) under which there may be issued or by which there may be secured any recourse Indebtedness of the Issuer or the Company (or by any Subsidiary, the repayment of which the Issuer has guaranteed or for which the Issuer is directly responsible or liable as obligor or guarantor), whether such Indebtedness now exists or shall hereafter be created, which default shall constitute a failure to pay an aggregate principal amount exceeding $25,000,000 of such Indebtedness when due and payable after the expiration of any applicable grace period with respect thereto and shall have resulted in such Indebtedness in an aggregate principal amount exceeding $25,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such Indebtedness having been discharged, or such acceleration having been rescinded or annulled, within a period of 10 days after there shall have been given, by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 10% in principal amount of the outstanding Notes a written notice specifying such default and requiring the Issuer to cause such Indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” hereunder; provided, however that $25,000,000 in this Section 1.4(e)(4) will be replaced with $5,000,000 for so long as any of the Issuer’s 2.750% Senior Notes due 2023, 3.750% Senior Notes due 2024, 3.125% Senior Notes due 2026 or 2.750% Senior Notes due 2027 are outstanding; or

(a) 100% of the principal amount of the Notes to be redeemed, and

(b) the sum of the present values as of the date of redemption of the remaining scheduled payments of principal of and interest on the Notes to be redeemed, after the date of redemption through the Par Call Date (assuming, for this purpose, that the Notes are scheduled to mature on the Par Call Date) (the “Assumed Remaining Life”) (exclusive of interest accrued to the applicable redemption date) discounted to such redemption date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points, plus, in the case of both clauses (a) and (b) above, any accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding. such Redemption Date.
