[1] On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new shareholder rights agreement (the “Pillarstone Rights Agreement”). Because Pillarstone REIT sought to use the Pillarstone Rights Agreement to prevent Whitestone OP from exercising its contractual Redemption Right, on July 12, 2022, Whitestone OP filed suit against Pillarstone REIT in the Court of Chancery of the State of Delaware challenging the Pillarstone Rights Agreement. On September 8, 2022, Whitestone OP’s Motion to Preserve the Status Quo was granted by the Court, limiting Pillarstone OP from engaging in any acts outside the ordinary course of business and otherwise imposing restrictions on Pillarstone OP to ensure that Whitestone’s right of redemption is not impaired while the underlying dispute is being considered by the Court. On January 25, 2024, the Delaware Court of Chancery: held that Pillarstone breached the implied covenant of good faith and fair dealing when it adopted the Pillarstone Rights Agreement that thwarted Whitestone OP from exercising the unfettered contractual redemption right it obtained in connection with its investment in the partnership; and the Court held that the Rights Plan was unenforceable as to the limited partner and allowed Whitestone OP to exercise its redemption right; allowed Pillarstone to determine the current value of the Partnership’s assets; and, as necessary, later enter a monetary judgment against Pillarstone for the difference between the amount Whitestone would have received in or around December 2021 and the current value. On January 25, 2024, the Company exercised its notice of redemption for substantially all of its investment in Pillarstone OP. On March 4, 2024, Pillarstone REIT authorized and filed the Chapter 11 bankruptcy of itself, Pillarstone OP, and the remainder of its special purpose entities in the United States Bankruptcy Court for the Northern District of Texas. As of the date of this filing, Whitestone has not received consideration for its redemption of its equity investment in Pillarstone OP as required by the partnership agreement. We intend to pursue collection of amounts due from Pillarstone OP through all means, including further litigation if necessary and while we do not know the ultimate amount to be collected, we believe the amount will be in excess of the current carrying value of our equity investment in Pillarstone OP.
