The Company shall pay interest (except Defaulted Interest) on the principal amount of the Notes on each January 15 and July 15 to the Persons who are Holders (as reflected in the Note Register at the close of business on January 1 and July 1 immediately preceding the Interest Payment Date), in each case, even if the Note is transferred or exchanged after such Regular Record Date, except as provided in Section 306(b) with respect to Defaulted Interest; provided that, with respect to the payment of principal, the Company shall make payment to the Holder that surrenders this Note to any Paying Agent on or after July 15, 2021.

The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes at the time outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and its consequences. Any such consent or waiver shall be binding upon all future Holders of this Note and of any Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. The Indenture also permits the Company and the Trustee, without notice to or consent of the Holders of the Notes, to enter into one or more indentures supplemental thereto for the purposes specified in the Indenture.

Successor Persons.

When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person shall be released from those obligations, subject to certain exceptions and conditions.

Remedies for Events of Default.

If an Event of Default with respect to the Notes occurs and is continuing, either the Trustee or the Holders of at least 25% of the aggregate principal amount of the outstanding Notes may declare the principal of all the Notes, and accrued and unpaid interest, if any, thereon, to be due and payable immediately. At any time after the Notes have been accelerated, but before a judgment or decree based on acceleration has been obtained, the Holders of a majority of the aggregate principal amount of outstanding Notes may, under certain circumstances provided in the Indenture, rescind and annul such acceleration.

Trustee Dealings with Company.

The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not the Trustee; provided, however, that, if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.
