Item 1.01. Entry Into a Material Definitive Agreement.

The disclosure set forth below under Item 1.02 of this Current Report on Form 8-K is incorporated by reference herein.

Item 1.02. Termination of a Material Definitive Agreement.

As previously disclosed, on April 11, 2023, we and DHC entered into an Agreement and Plan of Merger, or the Merger Agreement, pursuant to which we and DHC agreed that DHC would merge with and into us, with us as the surviving entity in the merger, subject to the terms and conditions of the Merger Agreement. On September 1, 2023, we and DHC mutually agreed to terminate the Merger Agreement and entered into a termination agreement, or the Termination Agreement. The mutual termination of the Merger Agreement was separately recommended by our and DHC’s respective Special Committee and approved by our and DHC’s respective Board of Trustees.

Pursuant to the Termination Agreement, the termination of the Merger Agreement is effective as of September 1, 2023. Neither we nor DHC will be required to pay any termination fee as a result of the mutual decision to terminate the Merger Agreement. We and DHC will bear our and their respective costs and expenses related to the Merger Agreement and the transactions contemplated thereby in accordance with the terms of the Merger Agreement.

The foregoing description of the Merger Agreement and the Termination Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which was previously filed as Exhibit 2.1 to our Current Report on Form 8-K on April 12, 2023, and the full text of the Termination Agreement, which is attached hereto as Exhibit 10.1 and incorporated by reference herein.

Contemporaneously with the execution of the Merger Agreement, on April 11, 2023, we and our manager, The RMR Group LLC, or RMR, entered into a Third Amended and Restated Property Management Agreement, or the Amended Property Management Agreement. The effectiveness of the Amended Property Management Agreement was conditioned upon the consummation of the merger. Since the merger will not be consummated, the Amended Property Management Agreement will not become effective and the Second Amended and Restated Property Management Agreement between us and RMR will remain in effect.

Item 8.01. Other Information.

On September 1, 2023, we and DHC issued a joint press release announcing the mutual termination of the Merger Agreement and the cancellation of our and DHC’s respective special meetings of shareholders to be held in connection with the Merger Agreement. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
