The Contribution and Exchange Agreement includes customary representations, warranties, covenants and indemnities of the Partnership and the Contributor and also provides for the Contributor to pay the Partnership at closing an amount of cash equal to the aggregate amount of cash receipts attributed to the Properties that were received by the Contributor on or after July 1, 2026. The acquisition is expected to close on October 30, 2026, subject to customary closing conditions.

No material relationship exists between the Partnership and the Contributor.
