TO THE INDENTURE

Dated as of April 6, 2020

5.75% Convertible Senior Notes due 2023

Doc#: US1:13888519v5

THIS FIRST SUPPLEMENTAL INDENTURE is dated as of June 30, 2020, among Carnival Corporation, a corporation duly organized and existing under the laws of the Republic of Panama, as issuer (the “Company”), Carnival plc, a company incorporated and registered under the laws of England and Wales (“Carnival plc”), the Subsidiary Guarantors listed on the signature pages hereto and U.S. Bank National Association, a national banking association organized under the laws of the United States of America, as trustee (the “Trustee”).

RECITALS

WHEREAS, the Company, Carnival plc, the Subsidiary Guarantors and the Trustee executed and delivered an Indenture, dated as of April 6, 2020 (the “Indenture”), to provide for the issuance by the Company of its 5.75% Convertible Senior Notes due 2023 (the “Notes”);

WHEREAS, pursuant to Section 10.01(a) of the Indenture, the Company, the Guarantors and the Trustee may amend the Indenture without the consent of any Holders to cure any ambiguity, mistake, omission, defect or inconsistency in the Indenture in a manner that does not adversely affect any Holder in any material respect, as set forth in an Officer’s Certificate;

WHEREAS, Section 14.01(b)(iv) incorrectly references calendar quarters instead of fiscal quarters in determining quarterly periods during which the Notes may be convertible, and the Company’s fiscal year-end is not the calendar year-end;

WHEREAS, the parties wish to correct this mistake commencing with the fiscal quarter ending August 31, 2020 (without, however, impacting any Holder’s rights to convert its Notes during the calendar quarter ending September 30, 2020); and

WHEREAS, the entry into this First Supplemental Indenture by the parties hereto is in all respects authorized by the provisions of the Indenture.

NOW, THEREFORE, for and in consideration of the foregoing premises, the Company, the Guarantors and the Trustee mutually covenant and agree as follows:

ARTICLE I.

Section 1.1 Amendments to the Indenture.

Section 14.01(b)(iv) of the Indenture is hereby amended and restated as follows:

“(iv) Prior to the close of business on the Business Day immediately preceding January 1, 2023, a Holder may surrender all or any portion of its Notes in an Authorized Denomination for conversion at any time during any fiscal quarter of the Company commencing after the fiscal quarter of the Company ending on May 31, 2020 (and only during such fiscal quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days

First Supplemental Indenture

Doc#: US1:13888519v5

ending on the last Trading Day of the immediately preceding fiscal quarter of the Company is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine whether the Notes are convertible because the Last Reported Sale Price condition has been met and promptly provide written notice to the Holders, the Trustee and the Conversion Agent (if other than the Trustee). Notwithstanding the first sentence above, a Holder may surrender all or any portion of its Notes in an Authorized Denomination for conversion at any time during the period commencing on July 1, 2020 and ending on September 30, 2020, as if this Section 14.01(b)(iv) continued to refer to calendar quarter rather than fiscal quarter.”
