**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

The information contained in "Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer" contained in the Schedule 13D is hereby amended to include the following:

On February 2, 2023, in connection with the proposed acquisition of the Issuer by the Purchaser pursuant to a tender offer for all of the outstanding Common Shares (other than the Common Shares owned by ABP Acquisition LLC or ABP Trust), at a price of $1.31 per share (the "Proposed Transaction"), DHC entered into a Consent and Amendment Agreement (the "Consent Agreement") with the Purchaser, ABP Acquisition LLC, ABP Trust and Adam D. Portnoy (collectively, the "Requesting Parties").

Pursuant to the Consent Agreement, DHC: (1) consented to the Issuer's granting of certain exceptions to the ownership restrictions set forth in its charter to the Requesting Parties in connection with the Proposed Transaction, (2) waived any default under its Master Management Agreement and Guaranty Agreement with the Issuer (the "DHC/ALR Agreements") arising or resulting from the Proposed Transaction, (3) agreed to tender all of the 10,691,658 Common Shares that the Reporting Persons own, representing an aggregate of 31.9% of the outstanding Common Shares, into the tender offer at the tender offer price, subject to the right, but not the obligation, to purchase, in a single private transaction, on or before December 31, 2023, a number of shares of common stock of the surviving entity in the Proposed Transaction constituting a percentage up to 31.9% of the then issued and outstanding shares of the common stock of the surviving entity based on the tender offer price and otherwise pursuant to a stockholders agreement to be entered into at the time of any such purchase on such terms as are negotiated and mutually agreed by the parties, and (4) agreed to amend the DHC/ALR Agreements to eliminate any change of control default or event of default provisions effective upon the consummation of the Proposed Transaction. The foregoing description of the Consent Agreement is not complete and is qualified in its entirety by reference to the full text of the Consent Agreement, a copy of which is filed to this Schedule 13D as Exhibit 99.7.

On February 2, 2023, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with ABP Acquisition LLC ("Parent") and the Purchaser, pursuant to which, and upon the terms and subject to the conditions thereof, on February 17, 2023, the Purchaser commenced a tender offer (the "Offer") to acquire all of the outstanding Common Shares (other than Common Shares held by Parent, the Purchaser, any other direct or indirect wholly owned subsidiary of Parent or any person that owns, directly or indirectly, all of the outstanding equity interests of the Purchaser) at a price of $1.31 per share, net to the seller in cash, without interest (such amount per Share, the "Offer Price"), subject to any withholding of taxes. The Merger Agreement also provides that, among other things, following the consummation of the Offer and subject to the terms and conditions of the Merger Agreement, the Purchaser will merge with and into the Issuer, with the Issuer being the surviving corporation (the "Merger"). The terms of the Offer, and the conditions to which it is subject, are set forth in the combined Tender Offer Statement and Rule 13e-3 Transaction Statement filed under cover of Schedule TO by Parent on February 17, 2023 (as amended or supplemented from time to time, the "Schedule TO"), which contains as exhibits an Offer to Purchase dated February 17, 2023 (the "Offer to Purchase"), and the related Letter of Transmittal (the "Letter of Transmittal," which together with the Offer to Purchase, as each of them may be amended or supplemented from time to time, contain the terms of the Offer). In response to the Offer, the Issuer filed a Solicitation/Recommendation Statement on Schedule 14D-9 on February 17, 2023. The Offer will expire at one minute after 11:59 p.m., Eastern Time, on March 17, 2023, unless the Offer is extended.
