  **Recitals**
  A.  Emeritus Properties IX, LLC, a Washington limited liability company (the Original Borrower or Operating Lessee), is indebted to the Lender with respect to a loan (the Loan) in the original principal amount of TEN MILLION THREE HUNDRED NINETY-FIVE THOUSAND AND NO/100 DOLLARS ($10,395,000.00).
  B.  The Loan is evidenced by that certain Fixed Rate Note dated September 29, 1999 (the Note), made by the Original Borrower, in the original principal amount of $10,395,000.00, payable to the order of AMRESCO Capital, L.P. (the Original Lender).
  C.  The Note is secured by, inter alia, that certain Mortgage and Security Agreement dated of even date with the Note (the Mortgage), executed by the Original Borrower to the Original Lender, which Mortgage was recorded in Deed Book 10436, Page 268 in the Registry of Deeds of Middlesex County, Massachusetts (the Records), and by that certain Assignment of Leases and Rents dated of even date with the Note (the Assignment of Rents) recorded in Deed Book 10437, Page 1 in the Records. Capitalized terms used but not defined herein  shall have the meanings ascribed to them in the Mortgage.
  D.  The Note, the Mortgage, the Assignment of Rents, the Guaranty (hereinafter defined) and that certain Environmental Liabilities Agreement dated of even date with the Note and executed by Original Borrower in favor of Lender (the Environmental Indemnity), together with any other instruments, certificates, assignments, opinions, and other documents and instruments of writing evidencing, guaranteeing, securing or pertaining to the Loan, are sometimes hereinafter collectively referred to as the Loan Documents.
  E.  In connection with the execution and delivery of the Loan Documents, the Original Guarantor represented to the Original Lender that it was an affiliate of the Original Borrower and that it would derive substantial economic benefit from the Original Lender making the Loan to the Original Borrower, and, as the Original Guarantor, it undertook certain obligations and agreements and assumed certain liabilities under, pursuant to, and in accordance
  [SB043500.194]    with the Loan Documents, including those set forth in that certain Guaranty dated of even date with the Note (the Guaranty), by the Original Guarantor in favor of the Original Lender.
  F.  The Original Guarantor, by its execution hereof, hereby acknowledges, ratifies and re-affirms its obligation to pay and perform each and all of the obligations, agreements and liabilities of Guarantor under, pursuant to, and in accordance with the Guaranty as fully and completely as if it were re-executing and re-delivering the Guaranty as of the date of this Agreement. Original Guarantor acknowledges and agrees that notwithstanding the assumption of Original Guarantors obligations under the Guaranty by New Guarantor as set forth in this Agreement, Original Guarantor is in no way released from Original Guarantors obligations as set forth in the Guaranty whether now existing or hereafter arising, but is and shall continue to be firmly bound to pay and perform all indebtedness and obligations as required by the terms of the Guaranty, until payment in full of all indebtedness secured by the Mortgage. The obligations of Original Guarantor and New Guarantor shall be joint and several.
  G.  Lender is the current holder of all of the Original Lenders interest in the Loan and Loan Documents.
  H.  Original Borrower has agreed to sell and HCRI Drum Hill Properties, LLC, a Delaware limited liability company (the New Borrower) has agreed to purchase, that certain real property more particularly described on Exhibit A attached to the Mortgage, together with all other property encumbered by the Mortgage or the other Loan Documents except as set forth below (collectively, the Property). Notwithstanding the foregoing, the parties recognize and agree that Original Borrower is not transferring to New Borrower any of the following: (a) licenses, permits, certificates, approvals and other intangible personal property of every kind and nature whatsoever owned by Original Borrower as of the date hereof and related to the operation of the Assisted Living Facility, (b) cash (on hand or in banks) and accounts, notes, interest and other receivables arising from the operation of the Assisted Living Facility prior to the date hereof or hereafter accruing, (c) all inventories of every kind and nature whatsoever (specifically including, but not limited to, all pharmacy supplies, medical supplies, office supplies and foodstuffs) owned by Original Borrower as of the date hereof and relating to the Assisted Living Facility, (d) all rights to the telephone numbers of the Assisted Living Facility and its sequential numbers, and (e) medical records, administrative records, manuals, and other books and records relating directly to the operation of the Assisted Living Facility. The parties further recognize and agree that any such items of excluded property shall continue to be owned by Original Borrower who, as Operating Lessee, will lease the Assisted Living Facility back from New Borrower, that such items are pledged as collateral to secure Operating Lessees obligations under the Operating Lease (hereinafter defined) for the benefit of New Borrower and, in turn, also for the benefit of Lender under the Assignment of Rents.
  I.  Simultaneously with the transfer and assumption, Original Borrower and New Borrower will enter into a Lease Agreement (the Operating Lease) whereby Original Borrower (herein Operating Lessee in such context) will lease the Property back from New Borrower and, in addition to seeking Lenders consent to the transfer and assumption, Original Borrower and New Borrower have requested Lenders consent to New Borrowers lease of the Property to Original Borrower as Operating Lessee pursuant to the Operating Lease.
  [SB043500.194]    J.  The Original Borrower and the New Borrower have requested that the Lender consent to the transfer and the lease, subject to the Mortgage, the Assignment of Rents and the other Loan Documents, and subject to the assumption by the New Borrower of the Loan and the obligations of the Original Borrower under the Loan Documents (collectively hereinafter, the Transfer and Assumption). The Lender has required, among other things, as a condition of its consent to the Transfer and Assumption, that the Assuming Guarantor, effective from and after the date hereof, become obligated and responsible for the performance of each and all of the obligations and agreements of the Original Guarantor under the Guaranty, and that the Assuming Guarantor, effective from and after the date hereof, become liable and responsible for each and all of the liabilities of the Original Guarantor thereunder, as fully and completely as if the Assuming Guarantor had originally executed and delivered the Guaranty. In addition, the Lender has required, as a condition of its consent to the Transfer and Assumption, that the New Borrower, in accordance with the terms and conditions of an Assumption Agreement (herein so called) dated of even date herewith, effective from and after the date hereof, become obligated and responsible for the performance of each and all of the obligations and agreements of the Original Borrower under the Loan Documents including those under the Environmental Indemnity, and that the New Borrower, effective from and after the date hereof, become liable and responsible for each and all of the liabilities of the Original Borrower thereunder, as fully and completely as if the New Borrower had originally executed and delivered the Environmental Indemnity.
  K.  The Lender, the Original Guarantor and the Assuming Guarantor, by their respective executions hereof, evidence their consent to the assumption, effective from and after the date hereof, by the Assuming Guarantor of each and all of the obligations, agreements and liabilities of the Original Guarantor under the Guaranty upon the terms and conditions hereinafter set forth.

  4.  **Transfer Fee and Other Fee** . The effectiveness and validity of this Agreement, and the consent of the Lender to the Transfer and Assumption, is expressly conditioned upon the Lenders receipt, in accordance with the provisions of the Loan Documents of the non-refundable application fee, the transfer or assumption fee and any and all other fees, payments or reimbursements payable to the Lender in connection with the transactions set forth herein.

  13.  **Multiple Counterparts** . This Agreement may be executed in multiple counterparts, each of which will be an original, but all of which, when taken together, will constitute one and the same Agreement.
