Pending Merger with Diversified Healthcare Trust

On April 11, 2023, we and Diversified Healthcare Trust, or DHC, entered into an Agreement and Plan of Merger, or the Merger Agreement, pursuant to which, on the terms and subject to the satisfaction or waiver of the conditions thereof, DHC will be merged with and into us, with us continuing as the surviving entity in the merger, or the Merger.

Pursuant to the terms and subject to the conditions and limitations set forth in the Merger Agreement, at the date and time the Merger becomes effective, or the Effective Time, each common share of beneficial interest, $ 0.01 par value per share, of DHC, or the DHC Common Shares, issued and outstanding as of immediately prior to the Effective Time will be automatically converted into the right to receive 0.147 (such ratio, the Exchange Ratio) of our common shares of beneficial interest, $ 0.01 par value per share, or our common shares, subject to adjustment for certain reclassifications, distributions, recapitalizations or similar transactions and other exceptional distributions as described in the Merger Agreement, with cash paid in lieu of fractional shares.

Other than as provided in the Merger Agreement, the Exchange Ratio is fixed and will not be adjusted to reflect changes in the market price of our common shares or the DHC Common Shares prior to the Effective Time.

Our common shares issued and outstanding immediately prior to the Effective Time will remain issued and outstanding common shares of beneficial ownership of the surviving entity following the Merger.

In connection with the Merger, we expect to change our name to “Diversified Properties Trust” and, following the Effective Time, will change our ticker symbol to “DPT.”

The transactions contemplated by the Merger Agreement and the terms thereof were evaluated, negotiated and recommended to our Board of Trustees, or our Board, by a special committee of our Board, or the OPI Special Committee, and to DHC’s board of trustees, or the DHC Board, by a special committee of DHC’s Board, or the DHC Special Committee, each consisting of disinterested, independent trustees of us and DHC, respectively.

Following the recommendations of the OPI Special Committee and the DHC Special Committee, our Board and the DHC Board each approved the Merger Agreement and the transactions contemplated thereby and resolved to recommend that the OPI and DHC shareholders, respectively, vote in favor of approval of the Merger and the transactions contemplated thereby.

Our shareholders will be asked to vote on the approval of the Merger and related matters, including the issuance of our common shares in the Merger, at a special meeting of our shareholders.

The consummation of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among others:

(1) the approval of the Merger by the affirmative vote of at least a majority of all the votes entitled to be cast by holders of outstanding DHC Common Shares at the meeting held for that purpose;

(2) the approval of the Merger by the affirmative vote of at least a majority of all the votes entitled to be cast by holders of our outstanding common shares at the meeting held for that purpose;

(3) the approval of the issuance of our common shares to be issued in the Merger, or the Share Issuance, by the affirmative vote of at least a majority of all votes cast by holders of our outstanding common shares at the meeting held for that purpose;

(4) the absence of any statute, rule or regulation by any governmental entity of competent jurisdiction or any temporary, preliminary or permanent judgment, order or decree by any court of competent jurisdiction which would prohibit or make illegal or prevent the consummation of the Merger or any of the transactions contemplated by the Merger Agreement;

and (9) the other party’s representations and warranties being accurate (subject to certain customary materiality exceptions) and the other party having performed or complied in all material respects with its agreements and covenants in the Merger Agreement.

The Merger Agreement contains certain customary representations, warranties and covenants, including covenants providing that we and DHC will use reasonable best efforts to conduct our and its respective businesses in all material respects in the ordinary course during the period between the execution of the Merger Agreement and the earlier of the Effective Time or the termination of the Merger Agreement, and to refrain from taking certain types of actions without the other party’s consent during the period between the execution of the Merger Agreement and the earlier of the Effective Time or the termination of the Merger Agreement, subject in each case to specified exceptions.

In connection with the execution of the Merger Agreement, we entered into a commitment letter, dated as of April 11, 2023, with JPMorgan Chase Bank, N.A., or JPM, pursuant to which JPM committed to provide, subject to the terms and conditions of the commitment letter, a senior secured bridge facility to us in an aggregate principal amount of $ 368,000 .

As of June 30, 2023, we have issued four mortgage notes with an aggregate principal balance of $ 108,120 secured by properties that previously collateralized the senior secured bridge facility, and as a result, we subsequently amended the commitment letter to reduce the principal amount of the senior secured bridge facility to $ 259,880 .
