ITEM 4. Ownership.

(a) Amount beneficially owned:

SNH beneficially owns 3,235,000 Shares of Common Stock of the Issuer, which it acquired pursuant to a lease realignment agreement with the Issuer, entered into on August 4, 2009.

Neither RMR nor RMR Trust holds any Shares of Common Stock of the Issuer. RMR, as manager of SNH, 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 3,235,000 Shares of Common Stock beneficially owned by SNH, but each disclaims such beneficial ownership.

Mr. Barry Portnoy beneficially owns 168,122 Shares of Common Stock of the Issuer. Mr. Adam Portnoy beneficially owns 24,000 Shares of Common Stock of the Issuer (of which 14,000 are subject to vesting requirements and will become fully vested, subject to the lapse of certain contingencies, annually through 2012). 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 power over) the 3,235,000 Shares of Common Stock beneficially owned by SNH, but each disclaims such beneficial ownership.

CUSIP No. 33832D106 13G Page 9 of 12 Pages

(b) Percent of class:

SNH beneficially owns approximately 9.1% of the Issuer’s Common Stock.

Each of Mr. Barry Portnoy and Mr. Adam Portnoy beneficially owns less than 1% of the Issuer’s Common Stock, and RMR and RMR Trust beneficially own none of the Issuer’s Common Stock. Reference is made to Item 4(a) above as to the Issuer’s Common Stock beneficially owned by SNH 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 Shares of Common Stock were beneficially owned by such persons, their respective percentage beneficial ownership of the Issuer’s Common Stock would be approximately 9.1%, 9.1%, 9.6% and 9.2%.

(c) Number of shares as to which such person has:

(i) Sole power to vote or direct the vote:

SNH:	3,235,000
RMR:	0
RMR Trust:	0
Barry M. Portnoy:	168,122
