Item 4.

Ownership.

(a)          Amount beneficially owned:

HPT beneficially owns 2,540,000 Common Shares of the Issuer, 1,540,000 of which were acquired by HPT pursuant to a rent deferral agreement with the Issuer, entered into on August 11, 2008, and 1,000,000 of which were purchased by HPT as part of an underwritten public offering of common shares by the Issuer completed on May 27, 2011.

Neither RMR nor RMR Trust holds any Common Shares of the Issuer.  RMR, as manager of HPT, 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 2,540,000 Common Shares beneficially owned by HPT, but each disclaims such beneficial ownership.

Mr. Barry Portnoy beneficially owns 54,911.6 Common Shares of the Issuer.  Mr. Adam Portnoy beneficially owns 49,763.8 Common Shares of the Issuer (of which 29,900 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

CUSIP No. 894174101

to beneficially own (and have shared voting and dispositive power over) the 2,540,000 Common Shares beneficially owned by HPT, but each disclaims such beneficial ownership.

(b)         Percent of class:

HPT beneficially owns approximately 9.1% of the Issuer’s Common Shares.

Each of Mr. Barry Portnoy and Mr. Adam Portnoy beneficially owns less than 1% of the Issuer’s Common Shares, and RMR and RMR Trust beneficially own none of the Issuer’s Common Shares.  Reference is made to Item 4(a) above as to the Issuer’s Common Shares beneficially owned by HPT 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 were beneficially owned by such persons, their respective percentage beneficial ownership of the Issuer’s Common Shares would be approximately 9.1%, 9.1%, 9.2% and 9.2%.
