Unless all of the outstanding Series 2025B Junior Subordinated Notes have been redeemed as of March 15, 2035, the Company will appoint a calculation agent (the “Calculation Agent”) with respect to the Series 2025B Junior Subordinated Notes prior to the Reset Interest Determination Date preceding March 15, 2035. The Company or any of its affiliates may assume the duties of the Calculation Agent. The applicable interest rate for each Interest Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. If the Company or one of its affiliates is not the Calculation Agent, the Calculation Agent will notify the Company of the interest rate for the relevant Interest Reset Period promptly upon such determination. The Company will notify the Subordinated Note Indenture Trustee of such interest rate, promptly upon making or being notified of such determination. The Calculation Agent’s determination of any interest rate and its calculation of the amount of interest for any Interest Reset Period beginning on or after March 15, 2035 will be conclusive and binding absent manifest error, will be made in the Calculation Agent’s sole discretion and, notwithstanding anything to the contrary in the documentation relating to the Series 2025B Junior Subordinated Notes, will become effective without consent from any other person or entity. Such determination of any interest rate and calculation of the amount of interest will be on file at the Company’s principal offices and will be made available to any holder of the Series 2025B Junior Subordinated Notes upon request. In no event shall the Subordinated Note Indenture Trustee be the Calculation Agent, nor shall it have any liability for any determination made by or on behalf of such Calculation Agent.
