⁽³	⁾	^{The 2029 Series Cap represents the maximum aggregate principal amount of the 2029 Notes that may be purchased pursuant to the 2029 Notes Tender Offer. The Operating Partnership reserves the right, but is under no obligation, to further increase or decrease the Aggregate Maximum Tender Amount and/or the 2029 Series Cap at any time, without extending the Withdrawal Deadline (as defined herein) for the 2029 Notes Tender Offer or otherwise reinstating withdrawal or revocation rights of Holders, subject to applicable law, which could result in the Operating Partnership purchasing a greater or lesser aggregate principal amount of the 2029 Notes in the 2029 Notes Tender Offer. There can be no assurance that the Operating Partnership will exercise its right to further increase or decrease the Aggregate Maximum Tender Amount and/or the 2029 Series Cap. If the Operating Partnership increases or decreases the Aggregate Maximum Tender Amount and/or the 2029 Series Cap, the Operating Partnership reserves the right to extend the Expiration Date.}

⁽⁴	⁾	^{Per $1,000 principal amount of the 2029 Notes validly tendered (and not validly withdrawn) and accepted for purchase by the Operating Partnership. Excludes Accrued Interest (as defined herein), which will be paid on the 2029 Notes accepted for purchase by the Operating Partnership.}

The 2029 Notes Tender Offer consists of an offer on the terms and conditions set forth in the Offer to Purchase. The 2029 Notes Tender Offer is open to all registered holders (the “Holders”) of the 2029 Notes. The 2029 Notes Tender Offer is not conditioned upon any minimum aggregate principal amount of the 2029 Notes being tendered. The Operating Partnership will only accept for purchase the 2029 Notes up to an aggregate principal amount that will not exceed the 2029 Series Cap. The Operating Partnership reserves the right, but is under no obligation, to further increase or decrease the 2029 Series Cap at any time without extending the Withdrawal Deadline for the 2029 Notes Tender Offer or otherwise reinstating withdrawal or revocation rights of Holders, subject to applicable law, which could result in the Operating Partnership purchasing a greater or lesser aggregate principal amount of the 2029 Notes in the 2029 Notes Tender Offer.

Holders of the 2029 Notes must validly tender and not validly withdraw their 2029 Notes prior to or at the Expiration Date to be eligible to receive the applicable Tender Offer Consideration (as defined in the Offer to Purchase) and the Accrued Interest. Holders will receive the Tender Offer Consideration, as set forth in the table above, per $1,000 principal amount of the 2029 Notes validly tendered (and not validly withdrawn) and accepted for purchase pursuant to the 2029 Notes Tender Offer. The 2029 Notes tendered after the Expiration Date will not be valid and will not be purchased pursuant to the 2029 Notes Tender Offer.

The 2029 Notes may be subject to proration if the aggregate principal amount of the 2029 Notes validly tendered and not validly withdrawn would cause the 2029 Series Cap to be exceeded. If proration of the tendered 2029 Notes is required, the Operating Partnership will determine the final proration factor as soon as practicable after the Expiration Date.

Holders who validly tender their 2029 Notes, may validly withdraw their tendered 2029 Notes at any time (a) at or prior to the earlier of (i) the Expiration Date, and (ii) if the 2029 Notes Tender Offer is extended, the 10th business day after commencement of the 2029 Notes Tender Offer or (b) at any time after the 60th business day after commencement of the 2029 Notes Tender Offer if for any reason the 2029 Notes Tender Offer has not been consummated within 60-business days after commencement of the 2029 Notes Tender Offer (the “Withdrawal Deadline”).

Holders will also receive accrued and unpaid interest on the 2029 Notes validly tendered and accepted for purchase from the last interest payment date up to, but not including, the date the Operating Partnership initially makes payment for such 2029 Notes (“Accrued Interest”), which date is anticipated to be August 27, 2026 (the “Settlement Date”). The Operating Partnership intends to fund the Tender Offer Consideration for the 2029 Notes tendered in the 2029 Notes Tender Offer with cash on hand and/or borrowings under the $600,000,000 line of credit under the Operating Partnership’s Second Amended and Restated Credit Agreement. Additional terms and conditions of the 2029 Notes Tender Offer are set forth in the Offer to Purchase.

The 2029 Notes Tender Offer is subject to the satisfaction or waiver of certain conditions, and the Operating Partnership expressly reserves its right, subject to applicable law, to terminate the 2029 Notes Tender Offer at any time prior to the Expiration Date.
