WHEREAS, the Corporation proposes to issue the Bonds under and pursuant to the terms of its Indenture of Mortgage, dated as of June 19, 2020 (the “Indenture”), between the Corporation and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as previously supplemented and as further supplemented by the Seventh Supplemental Indenture dated as of November 16, 2020 (the “Supplemental Indenture”) relating to the Bonds. Terms used but not defined herein shall have the meanings assigned to them in the Indenture, as supplemented by the Supplemental Indenture.

WHEREAS, the Bonds are to bear interest at a rate per annum to be determined quarterly as set forth in the Supplemental Indenture.

For the purpose of appointing an agent to calculate the Interest Rate applicable to the Bonds as specified and described in the Supplemental Indenture, the Corporation and The Bank of New York Mellon Trust Company, N.A. hereby agree as follows:

2.    On each interest determination date, the Calculation Agent shall determine the Interest Rate applicable to the Bonds for the relevant Interest Period, as provided for and contemplated by the Supplemental Indenture. The Calculation Agent shall

notify the Corporation and the Trustee of such Interest Rate promptly after the determination thereof. The Calculation Agent shall perform such other actions and undertake such other duties of the Calculation Agent as are described in the Supplemental Indenture to be performed or undertaken by the Calculation Agent.

3.    The Calculation Agent shall exercise due care to determine the interest rates on the Bonds and shall communicate the same to the Corporation, the Trustee, The Depository Trust Company and any paying agent identified by the Corporation in writing as soon as practicable after each determination. The Calculation Agent will, upon the request of the Holder of any Bond, provide the interest rate then in effect with respect to such Bond and, if determined, the interest rate with respect to such Bond which will become effective on the next Interest Payment Date. No amendment to the provisions of the Bonds relating to the duties or obligations of the Calculation Agent hereunder may become effective without the prior written consent of the Calculation Agent, which consent shall not be unreasonably withheld.

The Corporation shall also indemnify the Calculation Agent for, and hold it harmless against, any and all loss, liability, damage, claim or expense (including the costs and expenses of defending against any claim (regardless of who asserts such claim) of liability) incurred by the Calculation Agent that arises out of or in connection with its accepting appointment as, or acting as, Calculation Agent hereunder, except such as may result from the gross negligence, willful misconduct or bad faith of the Calculation Agent or any of its agents or employees. The Calculation Agent shall incur no liability and shall be indemnified and held harmless by the Corporation for, or in respect of, any actions taken, omitted to be taken or suffered to be taken in good faith by the Calculation Agent in reliance upon (i) the opinion or advice of legal or other professional advisors satisfactory to it or (ii) written instructions from the Corporation. The Calculation Agent shall not be liable for any error resulting from the use of or reliance on a source of information used in good faith and with due care to calculate any interest rate hereunder. The provisions of this section shall survive the termination of this Agreement.

The Calculation Agent may be removed at any time upon 30 days’ notice by the filing with it of any instrument in writing signed on behalf of the Corporation and specifying such removal and the date when it is intended to become effective. Such resignation or removal shall take effect upon the date of the appointment by the Corporation, as hereinafter provided, of a successor Calculation Agent. If within 30 days after notice of resignation or removal has been given, a successor Calculation Agent has not been appointed, the Calculation Agent may, at the expense of the Corporation, petition a court of competent jurisdiction to appoint a successor Calculation Agent. A successor Calculation Agent shall be appointed by the Corporation by an instrument in writing signed on behalf of the Corporation and the successor Calculation Agent.
