        <Identifier>SCHEDULE L, PART IV, LINE (1) - 143 Sound Beach Avenue Associates, L.P.</Identifier>
        <Explanation>HSS subleases physician office space from HSS Properties Corporation, an affiliate, which, in turn, leases physician office space from 143 Sound Beach Avenue Associates, L.P. A son of Russell F. Warren, M.D., the former Surgeon-in-Chief of HSS and an elected member of HSS' Board of Trustees, is a part owner of 143 Sound Beach Avenue Associates, L.P., the lessor. HSS Properties Corporation entered into the original lease in October 2000, following a lengthy search for suitable office space in the area, and after an independent valuation of the terms of the lease by a professional, commercial real estate firm confirmed the fair market value of the terms. At that time, Dr. Warren was the Surgeon-in-Chief of HSS and an ex officio member of HSS' Board of Trustees. The potential conflict of interest was disclosed to HSS' Board of Trustees and to the Board of Trustees of HSS Properties Corporation. Dr. Warren recused himself from the review, deliberation and vote. In 2010, HSS Properties renewed the lease through 2021, at a reduced rental rate that reflected a change in the real estate market from the time of the original lease, as confirmed by an independent professional real estate firm. The same due diligence, disclosure and review process (including recusal of Dr. Warren) was followed when the lease was renewed in June 2010. The approvals of the original lease and of the renewal were made by the vote of the disinterested members of the respective Boards of HSS and HSS Properties Corporation. Amount of Transaction: $336,685 Description of Transaction: HSS Properties Corporation (an affiliate of HSS) made lease payments in 2012 for physician office space it leases that is owned by 143 Sound Beach Avenue Associates, L.P. HSS Properties subleases the space to HSS.</Explanation>
