Explanation of Responses:
(1)	Acquired pursuant to the Agreement and Plan of Merger, dated as of September 14, 2018, by and among the issuer, GOV MS REIT, a wholly owned subsidiary of the issuer, and Select Income REIT ("SIR") in exchange for 40,801 SIR common shares of beneficial interest having a market value of $7.36 per share on the effective date of the merger of SIR with and into GOV MS REIT (the "Merger"), based on the closing price of SIR's common shares of beneficial interest on such effective date.
(2)	Following the closing of the Merger on December 31, 2018, the issuer changed its name from Government Properties Income Trust to Office Properties Income Trust, and the issuer effected a reverse share split (the "Reverse Split") pursuant to which every four common shares of the issuer were converted and reclassified into one common share of the issuer, subject to the receipt of cash in lieu of fractional shares. The amounts set forth in the table are presented prior to giving effect to the impact of the Reverse Split.
