The underwriters for the transaction are J.P. Morgan Securities LLC, Mizuho Securities USA LLC, PNC Capital Markets LLC, and Wells Fargo Securities, LLC.

The Operating Partnership retains the option to redeem the notes of either series at any time, in whole or in part, upon not less than 10 and not more than 60 days’ prior written notice. The redemption price will equal the principal amount plus accrued interest, subject to a “make-whole” premium calculated under the terms of the indenture, with specific exceptions for redemptions on or after the maturity dates of each series.

The notes are subject to customary events of default, including nonpayment, failure to comply with the indenture agreements for a period of 90 days after notice, and certain bankruptcy, insolvency, and reorganization events.
