In accordance with the Adjustable Interest Rate (LIBOR) Act (the "LIBOR Act") and the regulation issued by the Board of Governors of the Federal Reserve System on Dec. 16, 2022, implementing the LIBOR Act (the "LIBOR Rule"), the applicable tenor of three month CME Term SOFR will be the reference rate for calculations of the amount of interest payable with respect to interest periods with reference rate determination dates occurring after June 30, 2023, and specifically August 15, 2023, in the case of the Notes.

In the case of the Notes, the replacement rate, and therefore calculation of the amount of interest payable on the above security for interest periods with reference rate determination dates that occur after June 30, 2023, will also include the applicable tenor spread adjustment of 0.26161 percent per annum, as specified in the LIBOR Act.
