GUARANTY OF PAYMENT

(Loan A)

     THIS GUARANTY OF PAYMENT (this “Agreement”) is made as of August 28, 2007, by SUNRISE SENIOR LIVING, INC., a corporation organized under the laws of the State of Delaware (“Guarantor”) in favor of CHEVY CHASE BANK, F.S.B., a federal savings bank, its successors and assigns, as Agent (“Agent”) for Lenders (individually a “Lender” and collectively, “Lenders”) party to the Loan Agreement (as hereinafter defined).

     IN ORDER to induce Lenders to make a loan in the principal amount of $30,000,000 (the “Loan”) to Sunrise Connecticut Avenue Assisted Living, L.L.C., a limited liability company organized under the laws of the Commonwealth of Virginia (“Borrower”) and in connection therewith to accept one or more Deed of Trust Notes (as amended, extended, restated, supplemented or otherwise modified from time to time, collectively, the “Note”) and a Deed of Trust, Assignment, Security Agreement and Fixture Filing (Loan A) (as amended, extended, restated, supplemented or otherwise modified from time to time, the “Deed of Trust”), all of even date herewith, made by Borrower in the aggregate principal sum of $30,000,000, which Loan is to be advanced pursuant to the terms of a Loan and Security Agreement (Loan A) of even date herewith by and among Borrower, Agent and Lenders named therein and party thereto (as amended, extended, restated, supplemented or otherwise modified from time to time, the “Loan Agreement”), Guarantor hereby covenants and agrees with Agent and Lenders as follows:

     1. Guaranty.

     Guarantor hereby unconditionally and irrevocably guarantees to Agent and Lenders: (a) the due and punctual payment in full (and not merely the collectibility) of the principal of the Note and the interest thereon, in each case when due and payable, whether on any installment payment date or at the stated or accelerated maturity, all according to the terms of the Note and the Deed of Trust; and (b) the due and punctual payment in full (and not merely the collectibility) of all other sums and charges which may at any time be due and payable in accordance with, or secured by, the Note, the Deed of Trust or any other document evidencing or securing the Loan (together with the Note and the Deed of Trust, the “Financing Documents”); and (c) the due and punctual performance of all of the other terms, covenants and conditions contained in the Note and the other Financing Documents, on the part of Borrower or any subsequent owner of the property more particularly described in the Deed of Trust (the “Property”) to be performed.

     2. Guaranty Unconditional.

     Guarantor expressly agrees that Agent may, in its sole and absolute discretion, without notice to or further assent of Guarantor, except as specifically set forth herein, and without in any way releasing, affecting or impairing the obligations and liabilities of Guarantor hereunder: (a) waive compliance with, or any defaults under, or grant any other indulgences with respect to, the Financing Documents; (b) with Guarantor’s prior written consent, modify, amend, change or terminate any provisions of the Financing Documents; (c) with Guarantor’s prior written consent, grant extensions or renewals of or with respect to the Note or the other Financing Documents; (d) with Guarantor’s prior written consent, effect any release, subordination,

compromise or settlement in connection with the Note and the other Financing Documents; (e) with Guarantor’s prior written consent, agree to the substitution, exchange, release or other disposition of all or any part of the Property, or any other collateral for the Loan; (f) make advances for the purpose of performing any term or covenant contained in any of the Financing Documents with respect to which Borrower or the then owner of the Property shall be in default; (g) with Guarantor’s prior written consent, assign or otherwise transfer the Financing Documents or this Agreement or any interest therein or herein; and (h) deal in all respects with Borrower or the then owner of the Property as if this Agreement were not in effect. The obligations of Guarantor under this Agreement shall be unconditional, irrespective of the genuineness, validity, regularity or enforceability of the Note or the Deed of Trust, or any security given therefor or in connection therewith, or any other circumstances which might otherwise constitute a legal or equitable discharge of a surety or guarantor.

     3. Guaranty Primary.

     The obligations and liability of Guarantor under this Agreement shall be primary, direct and immediate; shall not be conditional or contingent upon pursuit by Agent of any remedies it may have against Borrower with respect to the Financing Documents, whether pursuant to the terms thereof or by law; and shall not be subject to any counterclaim, recoupment, set-off, reduction or defense based upon any claim that Guarantor may have against Borrower, Agent or any Lender. Without limiting the generality of the foregoing, Agent shall not be required to make any demand on Borrower and/or the then owner of the Property, or to sell at foreclosure or otherwise pursue or exhaust its remedies against the Property or any part thereof and/or against Borrower or the then owner of the Property, before, simultaneously with or after enforcing its rights and remedies hereunder against Guarantor. Any one or more successive and/or concurrent actions may be brought hereon against Guarantor either in the same action, if any, brought against Borrower and/or the then owner of the Property or in separate actions, as often as Agent may deem advisable.

     4. Waivers by Guarantor.

     Guarantor hereby unconditionally and irrevocably waives: (a) presentment and demand for payment of the principal of or interest on the Note and protest of non-payment; (b) notice of acceptance of this Agreement and of presentment, demand and protest; (c) except as set forth below, notice of any default under this Agreement or any of the Financing Documents and notice of all indulgences; (d) except as set forth below, demand for observance, performance, or enforcement of any terms or provisions of this Agreement or any of the Financing Documents; (e) any right or claim of right to cause a marshalling of the assets of Borrower; and (f) all other notices and demands otherwise required by law which Guarantor may lawfully waive.

     5. Reimbursement for Expenses.

     If Agent shall commence any action or proceeding for the enforcement of this Agreement, Guarantor shall reimburse Agent promptly upon demand, for all expenses incurred in connection therewith, including, without limitation, reasonable attorneys’ fees.

     6. Acceleration.

     Anything in this Agreement or in any of the Financing Documents to the contrary notwithstanding, Agent, at its option, may, as to Guarantor, accelerate the indebtedness evidenced and secured by the Financing Documents in the event of: (a) the making by Guarantor of an assignment for the benefit of creditors; (b) the appointment of a custodian for Guarantor, or for any property of Guarantor; (c) the commencement of any proceeding by Guarantor under any bankruptcy, reorganization, arrangement, insolvency, readjustment, receivership or like law or statute; or (d) the commencement of any proceeding against Guarantor under any bankruptcy, reorganization, arrangement, insolvency, readjustment, receivership or like law or statute which is not discharged or dismissed within ninety (90) days after institution thereof; or (e) the termination, dissolution or, liquidation of Guarantor, without the prior written consent of Agent. A change of control of Guarantor will not be a default hereunder or under any other Financing Document for this Loan so long as Guarantor continues to own one hundred percent (100%) of Sunrise Senior Living Management, Inc., Sunrise Senior Living Investments, Inc. and Sunrise Development, Inc. and the contracts between these entities and the Borrower remain in full force and effect.

     7. Subordination; Subrogation.

     If Guarantor shall advance any sums to Borrower or if Borrower shall hereafter become indebted to Guarantor, such sums and indebtedness shall be subordinate in all respects to the amounts then or thereafter due and owing to Lenders under the Financing Documents. Nothing herein contained shall be construed to give Guarantor any right of subrogation in and to the Note or the Deed of Trust or all or any part of Lenders’ interest therein, until all amounts owing to Lenders shall have been paid in full. Notwithstanding any provision of this Paragraph to the contrary, if Guarantor is or becomes an “insider” (as defined from time to time in Section 101 of the Federal Bankruptcy Code) with respect to Borrower, then Guarantor irrevocably and absolutely waives any and all rights of subrogation, contribution, indemnification, reimbursement or any similar rights against Borrower with respect to this Agreement, whether such rights arise under an express or implied contract or by operation of law. It is the intention of the parties hereto that Guarantor shall not be deemed to be a “creditor” (as defined in Section 101 of the Federal Bankruptcy Code) of Borrower by reason of the existence of this Agreement in the event that Borrower becomes a debtor in any proceeding under the Federal Bankruptcy Code.

     8. Representations and Warranties.

     Guarantor represents and warrants to Agent as follows:

          (a) Good Standing. Guarantor (a) is a corporation duly organized, existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power to own its property and to carry on its business as now being conducted, and (c) is duly qualified to do business and is in good standing in each jurisdiction in which the character of the properties owned by it therein or in which the transaction of its business makes such qualification necessary.

          (b) Power and Authority. Guarantor has full corporate power and authority to execute and deliver this Agreement and the other Financing Documents to which it is a party and

to incur and perform the Obligations (as defined in the Deed of Trust) whether under this Agreement, the other Financing Documents or otherwise, all of which have been duly authorized by all proper and necessary corporate action. No consent or approval of shareholders or any creditors of Guarantor, and no consent, approval, filing or registration with or notice to any Governmental Authority on the part of Guarantor, is required as a condition to the execution, delivery, validity or enforceability of this Agreement or the other Financing Documents or the performance by Guarantor of the Obligations.

          (c) Binding Agreements. This Agreement and the other Financing Documents executed and delivered by Guarantor have been properly executed and delivered and constitute the valid and legally binding obligations of Guarantor and are fully enforceable against Guarantor in accordance with their respective terms.

          (d) No Conflicts. Neither the execution, delivery and performance of the terms of this Agreement or of any of the other Financing Documents executed and delivered by Guarantor nor the consummation of the transactions contemplated by this Agreement will conflict with, violate or be prevented by (i) the charter or bylaws of Guarantor, (ii) any existing mortgage, indenture, contract or agreement binding on Guarantor or affecting its property, or (iii) any Laws.

          (e) Compliance with Laws. Guarantor is not in violation of any applicable Laws (including, without limitation, any Laws relating to employment practices, to environmental, occupational and health standards and controls) or order, writ, injunction, decree or demand of any court, arbitrator or any Governmental Authority affecting Guarantor or its properties, the violation of which, considered in the aggregate, are reasonably likely to materially adversely affect the business, operations or properties of Guarantor.

          (f) Litigation. Except as shown on the Form 8K provided to Lender, there are no proceedings, actions or investigations pending or, so far as Guarantor knows, threatened before or by any court, arbitrator or any Governmental Authority which, in any one case or in the aggregate, if determined adversely to the interests of Guarantor, would have a material adverse effect on the business, properties, condition (financial or otherwise) or operations, present or prospective, of Guarantor.

          (g) Financial Condition. On the date delivered, the draft financial statements of Guarantor dated June 30, 2006 were complete and correct and fairly presented the financial position of Guarantor and the results of its operations and transactions in its surplus accounts as of the date and for the period referred to and were prepared in accordance with GAAP applied on a consistent basis throughout the period involved. Subsequently the Guarantor provided additional information including cash and debt levels as of June 30, 2007 and there has been no material adverse change in the cash or debt levels of Guarantor since such reports. The representations and warranties contained in this Section shall also cover financial statements furnished from time to time to Agent pursuant to the Loan Agreement. Notwithstanding the foregoing, except as provided in Section 7.1 of the Loan Agreement, Guarantor will not be required to deliver financial statements or operating statement until ten (10) days after such statements have been made publicly available by the Securities and Exchange Commission.

There is no fact known to Guarantor which Guarantor has not disclosed to Agent in writing prior to the date of this Agreement which materially and adversely affects or in the future could, in the reasonable opinion of Guarantor materially adversely affect the condition, financial or otherwise, results of operations, business, or assets of Guarantor.

          (i) Financial Interest. Financial Interest. Guarantor will derive a benefit from the credit facilities extended to and the Obligations incurred by Borrower, and hereby waives any claim that Agent violated the Equal Credit Opportunity Act (15 U.S.C. 1691 et seq.) in connection with the Loan, any of the Financing Documents or any of the other Obligations or security for any obligation which is the subject thereto.
