The letter has been filed with the U.S. Securities and Exchange Commission and is available at www.dhcreit.com/mergerofdhcandopi with other materials related to the Special Meeting.

Full text of the letter follows:

DHC’s Merger with Office Properties Income Trust is the Best Available Opportunity
to Protect and Enhance the Value of Your Investment

Those Publicly Opposing the Merger are DHC Debtholders Who Would Benefit at the Expense of DHC Shareholders if the Merger is Rejected

Vote FOR On the White Card Today!

July 31, 2023

Dear Fellow DHC Shareholder,

The DHC Board of Trustees unanimously recommends that you vote FOR the merger with Office Properties Income Trust. We firmly believe the merger of DHC and OPI provides compelling value and is in the best interest of our Company and all DHC shareholders.

The merger offers DHC shareholders compelling value now, solves a series of severe and time-sensitive challenges for DHC related to the Company’s debt covenants, and preserves DHC shareholders’ ability to participate in the future upside of DHC’s business. Under the terms of the merger agreement, DHC shareholders will receive 0.147 shares of OPI for each common share of DHC, which represents a 20% premium to the 30-day average price prior to announcement of the merger and a 37% premium to the unaffected price1. With 42% ownership in the combined company, DHC shareholders will also be able to participate in the upside potential of a larger, stronger and more diversified REIT with enhanced access to capital and benefit from an immediate 267% increase over the dividend paid to DHC shareholders today.

Those Publicly Opposing the Merger are DHC Debtholders Who Would Benefit at the Expense of DHC Shareholders if the Merger is Rejected

Despite the compelling value the merger offers, a few investors have announced their intent to vote against the transaction. We believe these investors are opposing the merger for self-serving reasons, motivated by their investments in DHC’s bonds, which are contrary to the interests of long-term DHC shareholders. We believe these investors are trying to trick shareholders into rejecting the pending merger in order to force DHC into default, which would improve their position as DHC debtholders. An event of default, which is quite possible if the merger is not approved, would give these investors considerable leverage as the Company would be forced to refinance its debt under less favorable terms to the Company.

The Pending Merger With OPI Is the Best Strategic Alternative for DHC Shareholders

VOTE THE ENCLOSED WHITE PROXY CARD TODAY!

YOUR VOTE MATTERS: Only affirmative votes FOR the transaction count towards the votes required to approve the merger. A failure to vote is equivalent to a vote against the transaction. It is imperative that you vote FOR the transaction today using the WHITE proxy card.

Regardless of how many shares you own or whether you plan to attend the virtual Special Meeting of Shareholders, please follow the instructions on the WHITE proxy card to vote TODAY online, by telephone or by signing and returning the enclosed WHITE proxy card. Please discard any gold proxy card sent to you.

Thank you for your continued support.

Sincerely,

The DHC Board of Trustees

Warning Concerning Forward-Looking Statement

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws. Also, whenever DHC uses words such as “believe”, “expect”, “anticipate”, “intend”, “plan”, “estimate”, “will”, “may” and negatives or derivatives of these or similar expressions, it is making forward-looking statements. These forward-looking statements are based upon DHC’s present intent, beliefs or expectations, but forward-looking statements are not guaranteed to occur and may not occur. Actual results may differ materially from those contained in or implied by DHC’s forward-looking statements as a result of various factors. For example: (a) OPI and DHC have entered into a definitive merger agreement and the proposed merger is expected to close in the third quarter of 2023. However, the closing of the proposed merger is subject to the satisfaction or waiver of closing conditions, including DHC shareholder approval and the financing or any consents or approvals required or contemplated in connection with the proposed merger, some of which are beyond DHC’s control, and DHC cannot be sure that any or all of these conditions will be satisfied or waived. Accordingly, the proposed merger may not close on the contemplated terms or at all or it may be delayed; (b) OPI may not be able to recast its existing revolving credit facility on favorable terms as expected in connection with the proposed merger; (c) DHC shareholders are expected to benefit from an annual distribution of $1.00 per share of the combined company. However, the Board of Trustees of the combined company will consider many factors when setting distribution rates, and thus future distribution rates may be increased or decreased and DHC cannot be sure as to the rate at which future distributions will be paid; (d) the transactions contemplated by the merger agreement and the terms thereof were evaluated, negotiated and recommended to DHC’s Board of Trustees by a special committee of DHC’s Board of Trustees, comprised solely of DHC’s disinterested, independent trustees, and were separately approved by DHC’s independent trustees and by DHC’s Board of Trustees, and BofA Securities acted as exclusive financial advisor to DHC. Despite this process, DHC could be subject to claims challenging the proposed merger or other transactions or DHC’s entry into the merger agreement and related agreements because of the multiple relationships among DHC, OPI and The RMR Group LLC (“RMR”), the manager of DHC and OPI, and their related persons and entities or other reasons, and defending even meritless claims could be expensive and distracting to DHC management; and (e) this press release contains statements regarding the expectations for the proposed merger and the combined company which may imply that the combined company will achieve its expected strategic and financial goals and DHC shareholders will benefit from the growth potential of the combined company. However, the combined company will be subject to various risks, including: the risk that the combined businesses will not be integrated successfully or that the integration will be more costly or more time-consuming and complex than anticipated; the risk that cost savings and synergies anticipated to be realized by the proposed merger may not be fully realized or may take longer to realize than expected; risks associated with the impact, timing or terms of the proposed merger; the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement relating to the proposed merger; the risk of shareholder litigation in connection with the proposed merger, including resulting expense or delay; risks related to future opportunities, plans and strategy for the combined company, including the uncertainty of expected future financial performance, expected access to cash flows and capital, timing of accretion, distribution rates and results of the combined company following completion of the proposed merger and the challenges facing the industries in which each company currently operates and the combined company will, following the closing of the transaction, operate; risks related to the market value of the OPI common shares to be issued in the proposed merger; the expected qualification of the proposed merger as a tax-free “reorganization” for U.S. federal income tax purposes; the risk that the financing or any consents or approvals required or contemplated in connection with the proposed merger will not be received or obtained within the expected timeframe, on the expected terms or at all; the risk that the combined company will not be in compliance with its debt covenants; risks associated with expected financing transactions undertaken in connection with the proposed merger and risks associated with indebtedness incurred in connection with the proposed merger, including the potential inability to access, or reduced access to, the capital markets or other capital resources or increased cost of borrowings, including as a result of a credit rating downgrade; risks associated with the level of capital expenditures of each company and the combined company following the proposed merger, including possible changes in the amount or timing of capital expenditures; and risks associated with the impact of general economic, political and market factors on the combined company. As a result, the combined company may not achieve the long-term growth and value creation for shareholders as expected.

These risks, as well as other risks associated with the proposed transaction between DHC and OPI, are more fully discussed under “Risk Factors” in the definitive proxy statement filed by DHC with the Securities and Exchange Commission (the “SEC”) on July 21, 2023. The information contained in DHC's periodic reports filed with the SEC, including under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” or incorporated therein, also identifies important factors that could cause DHC's actual results to differ materially from those stated in or implied by DHC's forward-looking statements.
