** The Issuer expects that delivery of the Notes will be made to investors on or about September 26, 2024, which will be the third business day following the date hereof. Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the business day preceding the closing of the Notes hereunder will be required, by virtue of the fact that the Notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to the business day preceding the closing of the Notes should consult their advisors.

Investors are advised to carefully consider the investment objectives, risks, charges and expenses of the Issuer before investing. The Preliminary Prospectus, which has been filed with the Securities and Exchange Commission (the "SEC"), contains this and other information about the Issuer and should be read carefully before investing.
