(1) Represents the estimated maximum number of common shares of beneficial interest of Office Properties Income Trust (“OPI”), par value $.01 per share, estimated to be issued to holders of common shares of beneficial interest of Diversified Healthcare Trust (“DHC”), par value $.01 per share, in connection with the consummation of the merger of DHC with and into OPI (the “Merger”), with OPI as the surviving entity in the Merger. The number of common shares of beneficial interest of OPI (the “OPI Common Shares”) being registered is based upon the product of (A) 0.147, the exchange ratio in the Merger representing the OPI Common Shares expected to be exchanged for each common share of beneficial interest of DHC (the “DHC Common Shares”), and (B) 239,659,809, the number of DHC Common Shares outstanding as of May 17, 2023. The 239,659,809 DHC Common Shares outstanding includes the 994,200 DHC Common Shares outstanding in respect of unvested awards of DHC Common Shares awarded under DHC’s Amended and Restated 2012 Equity Compensation Plan.

(2) Estimated solely for the purpose of calculating the registration fee required by Section 6(b) of the Securities Act of 1933, as amended (the “Securities Act”), and calculated pursuant to Rules 457(f)(1) and 457(c) of the Securities Act. The proposed maximum aggregate offering price was calculated on the basis of (i) $0.87, the average of the high and low prices per share of the DHC Common Shares, on the Nasdaq Stock Market LLC on May 15, 2023 multiplied by (ii) 239,659,809, the maximum number of shares of the DHC Common Shares estimated to be cancelled and exchanged in the Merger.

(3) Calculated pursuant to Section 6(b) of the Securities Act at a rate equal to $110.20 per $1,000,000 of the proposed maximum aggregate offering price.
