The claimants seeks monetary relief in excess of $1,000,000 million in damages and equitable relief. However, the Company denies the claims, has substantial legal and factual defenses against the claims, and intends to vigorously defend against the claims. The Company does not believe a probable loss will be incurred, nor does it anticipate a material adverse effect on its financial position, results of operations, cash flows or liquidity. Therefore, the Company has not recorded a charge as a result of this action. *Former CEO Litigation* On February 23, 2022, the Company’s former CEO, James Mastandrea, filed suit against the Company and certain of its trustees (Nandita Berry, Jeff Jones, Jack Mahaffey, and David Taylor) and officers (David Holeman, Christine Mastandrea, Peter Tropoli) in the District Court of Harris County, Texas, alleging claims relating to the termination of claimant’s employment. Claimant purports to assert claims for breach of contract, breach of fiduciary duties, tortious interference with contract, civil conspiracy, and declaratory judgment. The claimant seeks a maximum of $25 million in damages and equitable relief. However, the Company denies the claims, has substantial legal and factual defenses against the claims, and intends to vigorously defend against the claims. The Company does not believe a probable loss will be incurred, nor does it anticipate a material adverse effect on its financial position, results of operations, cash flows or liquidity. Therefore, the Company has not recorded a charge as a result of this action. *Pillarstone Rights Plan* On December 26, 2021, the Board of Trustees of Pillarstone REIT adopted a new rights agreement (the “Pillarstone Rights Agreement”), pursuant to which each holder of Pillarstone REIT common stock received one preferred share purchase right (a “Right”) per common share held as of the applicable record date. Each Right entitles the registered holder to purchase from Pillarstone REIT one one-thousandth (a “Unit”) of a series D preferred share of Pillarstone at a purchase price (“Purchase Price”) of $7.00 per Unit, subject to adjustment. The Rights are exercisable upon the occurrence of certain events as described in the Pillarstone Rights Agreement, including the acquisition by certain holders of 5% or more of the common shares of Pillarstone REIT (an “Acquiring Person”). Upon the acquisition of Pillarstone REIT common shares by an Acquiring Person, each holder of a Right (other than an Acquiring Person), will have the right to receive upon exercise a number of Pillarstone REIT common shares having a market value of two times the Purchase Price. As set forth in the Amended and Restated Limited Partnership Agreement of Pillarstone OP, dated as of December 8, 2016 (the “Pillarstone Partnership Agreement”), we have the contractual right to have our limited partnership interests in Pillarstone redeemed at our discretion. However, upon receipt of a redemption notice, Pillarstone OP has the option of the applicable redemption price in cash, based on the market value of Pillarstone REIT common shares, or in Pillarstone REIT common shares. To the extent we seek to have our partnership units in Pillarstone OP redeemed and Pillarstone OP elects to pay the applicable redemption price in Pillarstone REIT common shares (and such shares represent 5% or more of the outstanding common shares of Pillarstone REIT), the Rights could become exercisable. To the extent the Rights are exercised as a result of our Pillarstone OP units being redeemed for Pillarstone REIT common shares, our ownership interest in Pillarstone REIT would be significantly diluted, which could adversely impact the value of our investment in Pillarstone OP. Because the Pillarstone Rights Agreement seeks 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 due to Pillarstone REIT’s breach of the Pillarstone OP partnership agreement, breach of its fiduciary duty as general partner of Pillarstone OP to Whitestone OP, and breach of the implied covenant of good faith and fair dealing under the Pillarstone OP partnership agreement. The lawsuit seeks rescission and voiding of the Pillarstone Rights Agreement; a declaration that the Pillarstone Rights Agreement is unenforceable, invalid, and of no force and effect; an order permanently enjoining enforcement of the Pillarstone Rights Agreement; an award of monetary damages; and broad restrictions on Pillarstone REIT’s ability to conduct its business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. On September 8, 2022, the Company’s Motion to Preserve the Status Quo was granted by the Court, limiting Pillarstone from engaging in any acts outside the ordinary course of business and otherwise imposing restrictions on Pillarstone to ensure that Whitestone’s right of redemption right is not impaired while the underlying dispute is being considered by the Court. While we do not believe the overall impact of the Pillarstone Rights Agreement on the carrying value of our investment in Pillarstone OP is material, we cannot reasonably estimate a range of possible loss at this time. We are subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.
