The Reporting Persons acquired the Common Shares reported herein for investment purposes.

The Reporting Persons may from time to time engage in discussions with the Issuer, its Trustees and officers, other shareholders of the Issuer and other persons on matters that relate to the management, operations, business, assets, capitalization, financial condition, strategic plans, governance and the future of the Issuer and/or its subsidiaries. The Reporting Persons and their affiliates may acquire or dispose of Common Shares, other shares of capital stock or equity interests of the Issuer and/or its subsidiaries, from time to time, in the open market, private transactions, through the Issuer’s dividend reinvestment plan, or otherwise, depending upon various factors, including without limitation, the Issuer’s business, prospects and financial condition, the market for such shares or interests, actions taken by the Issuer’s trustees, general economic and stock market conditions, proposals from time to time sought by or presented to them and other factors. Each Reporting Person intends to closely monitor its or his investments and may from time to time take advantage of opportunities presented to it or him. The Reporting Persons may in the future formulate plans or proposals regarding the Issuer and/or its subsidiaries, including possible future plans or proposals concerning events or transactions of the kind described in Item 4(a) through (j) of Schedule 13D.

On April 26, 2021, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) with TRMT. Upon the terms and subject to the conditions of the Merger Agreement, TRMT merged with and into the Issuer, with the Issuer continuing as the surviving entity in the merger (the “Merger”). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, and as provided in a letter agreement dated August 26, 2021 between the Issuer and TRMT (the “Letter Agreement”), at the effective time of the Merger (the “Effective Time”), each one (1) TRMT Common Share issued and outstanding immediately prior to the Effective Time was converted into the right to receive 0.516 of one (1) newly issued Common Share, subject to adjustment as described in the Merger Agreement, with cash paid in lieu of fractional shares. The Merger closed at 4:01 p.m. Eastern Time on September 30, 2021.

The foregoing summary of the Merger Agreement and the Letter Agreement is not intended to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement and the Letter Agreement, copies of which are filed as Exhibit 99.3 and Exhibit 99.4 hereto, respectively, and incorporated herein by reference.

Except as otherwise described above in this Item 4 and with respect to Adam D.

Voting and investment power with respect to the Common Shares beneficially owned by ABP Trust may be deemed to be shared by Adam D.

Portnoy may be deemed to beneficially own an aggregate of 1,078,247 Common Shares, consisting of the 175,426 Common Shares he directly holds and the 902,821 Common Shares beneficially owned by ABP Trust, representing approximately 7.4% of the Common Shares outstanding as of September 30, 2021.
