Item 4.Ownership.

(a)Amount beneficially owned:

CWH beneficially owns 9,950,000 Common Shares of Beneficial Interest of the Issuer, which it acquired in connection with an investment when the Issuer was formed.

Neither RMR nor RMR Trust holds any Common Shares of Beneficial Interest of the Issuer.  RMR, as manager of CWH, and RMR Trust, as the sole member of RMR, may, under applicable regulatory definitions, be deemed to beneficially own (and have shared voting and dispositive power over) the 9,950,000 Common Shares of Beneficial Interest beneficially owned by CWH, but each disclaims such beneficial ownership.

Mr. Barry Portnoy beneficially owns 5,032.107 Common Shares of Beneficial Interest of the Issuer.  Mr. Adam Portnoy beneficially owns 13,750 Common Shares of Beneficial Interest of the Issuer (of which 4,600 are subject to vesting requirements and will become fully vested, subject to the lapse of certain contingencies, annually through 2014).  In their respective positions with RMR and RMR Trust, described in Item 2(a) above, Mr. Barry Portnoy and Mr. Adam Portnoy may also be deemed to beneficially own (and have shared voting and dispositive

CWH beneficially owns approximately 21.1% of the Issuer’s Common Shares of Beneficial Interest.

Each of Mr. Barry Portnoy and Mr. Adam Portnoy beneficially owns less than 1% of the Issuer’s Common Shares of Beneficial Interest, and RMR and RMR Trust beneficially own none of the Issuer’s Common Shares of Beneficial Interest.  Reference is made to Item 4(a) above as to the Issuer’s Common Shares of Beneficial Interest owned by CWH that may, under applicable regulatory definitions, be deemed to be beneficially owned by RMR, RMR Trust, Mr. Barry Portnoy or Mr. Adam Portnoy.  If all such Common Shares of Beneficial Interest were beneficially owned by such persons, their respective percentage beneficial ownership of the Issuer’s Common Shares of Beneficial Interest would be approximately 21.1%, 21.1%, 21.2% and 21.2%.
