There have been no material changes to the information previously reported in the Original Schedule 13D with respect to the Reporting Persons.

Item 4.

Purpose of Transaction.

“Item 4. Purpose of Transaction” of the Original Schedule 13D is hereby amended and restated as follows:

Senior Housing and other Reporting Persons acquired the Shares reported in this Schedule 13D for investment purposes.  The Reporting Persons previously reported their beneficial ownership of the Shares on Schedule 13G, initially filed on August 12, 2009 and amended on January 20, 2010.

The Issuer was Senior Housing’s wholly owned subsidiary until December 31, 2001, when the Issuer’s Shares were spun off to Senior Housing’s shareholders.  Senior Housing’s primary reason for the spinoff related to certain requirements under Federal income tax laws for Senior Housing’s maintenance of its status as a REIT.  Among other things, to remain a REIT, Senior Housing, in most cases, was required to derive a substantial majority of its revenues from real estate rents and mortgage interest.  For tax years beginning in 2009, there was a change in the

REIT qualification requirements in the Internal Revenue Code which permits REITs to receive the financial results of health care facilities’ operations, as well as rents from those operations, provided these results are received by a taxable REIT subsidiary (a “TRS”).

Since the time of the spinoff, Senior Housing and the Issuer have engaged in a number of transactions and have developed several contractual relationships.  Information about current transactions between Senior Housing and the Issuer appears in Senior Housing’s Annual Report on Form 10-K for its fiscal year ended December 31, 2009 (the “Senior Housing Annual Report”) and its other filings made with the SEC.  In particular, the Reporting Persons refer to (i) the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Related Person Transactions” in the Senior Housing Annual Report, (ii) the section captioned “Related Person Transactions and Company Review of Such Transactions” in Senior Housing’s Proxy Statement dated February 22, 2010 relating to its 2010 Annual Meeting of Shareholders, (iii) Item 1.01 in Senior Housing’s Current Report on Form 8-K filed with the SEC on January 13, 2010, and (iv) the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Related Person Transactions” in Senior Housing’s Quarterly Report on Form 10-Q for its fiscal quarter ended March 31, 2010. Copies of the information contained in such sections are filed as Exhibit 99.2 in Item 7 and such Exhibit 99.2 is incorporated herein by reference. The information contained in Exhibit 99.2 is presented as of the respective dates the related reports, as identified in such Exhibit, were filed with the SEC.

On May 12, 2010, Senior Housing’s Board of Trustees appointed a special committee consisting of its Independent Trustees and requested that the Issuer’s Board of Directors appoint a special committee consisting of its Independent Directors to consider, in light of the tax law changes described above and uncertainties created by recent changes in the market for healthcare services, including the recent adoption of the Patient Protection and Affordable Care Act and expected Medicare and Medicaid rate changes, whether Senior Housing and the Issuer should: (i) change one or more of the existing leases between Senior Housing, as lessor, and the Issuer, as lessee, to a management arrangement between a Senior Housing owned TRS and the Issuer as manager; (ii) combine the Issuer into a Senior Housing owned TRS; or (iii) otherwise change one or more of the contractual arrangements between Senior Housing and the Issuer or take other actions.  On May 12, 2010, the Issuer’s Board of Directors appointed a special committee consisting of its Independent Directors.  The special committees of the Boards of Senior Housing and of the Issuer conferred separately and together.  As a result of these discussions, Senior Housing and the Issuer mutually agreed that it is not advisable at this time to change the existing leases between Senior Housing and the Issuer into management arrangements, to combine the Issuer into a Senior Housing owned TRS or to otherwise change any contractual arrangement between them.  The special committees did decide that, in the future, in connection with the possible acquisition by Senior Housing of properties which may be operated by the Issuer, Senior Housing and the Issuer may consider management arrangements using a TRS structure, as well as leases, depending upon the circumstances of any such future acquisition.

Because of their close business relationships, the Reporting Persons, including Senior Housing, and the Issuer have discussions from time to time on a variety of matters; and, in the future, these

CUSIP NO. 33832D106

discussions may implicate some of the topics discussed by the special committees described above or other topics described in clauses (a) through (j) of Item 4.  There can be no assurance that any of the potential actions referred to above will or will not be undertaken in the future.

Item 5.

Interest in Securities of the Issuer.

There have been no material changes to the information previously reported in the Original Schedule 13D with respect to the Reporting Persons.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

There have been no material changes to the information previously reported in the Original Schedule 13D with respect to the Reporting Persons.
