[1]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. While we do not believe the overall impact of the Pillarstone Rights Agreement on the value of our investment in Pillarstone OP is material, we cannot reasonably estimate a range of possible loss at this time.[2]Representing eight property interests and 926,798 square feet of GLA, as of June 30, 2022 and December 31, 2021.[3]Operating lease right of use assets (net) $ 171 $ 222[4]Operating lease liabilities $ 171 $ 231

[1]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. While we do not believe the overall impact of the Pillarstone Rights Agreement on the value of our investment in Pillarstone OP is material, we cannot reasonably estimate a range of possible loss at this time.[2]Representing eight property interests and 926,798 square feet of GLA, as of June 30, 2022 and December 31, 2021.[3]The Company manages these real estate partnership investments and, where applicable, earns acquisition fees, leasing commissions, property management fees, and asset management fees.
