AGREEMENTS

NOW THEREFORE, in consideration of the premises and the agreements contained herein, the parties to this Agreement hereby agree as follows:

1.                                       DEFINITIONS.

(a)                                  The Loan Agreement, the Note, the Deed of Trust, and all other documents or instruments executed in connection therewith are hereinafter referred to, collectively, as the “Loan Documents”. Unless the context otherwise requires or unless otherwise expressly defined herein, the terms defined in the Loan Agreement shall have the same meanings whenever used in this Agreement.

(b)                                 The definition of “Defaulting Lender” in Exhibit B of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

“Defaulting Lender” means (a) a Lender that fails to pay its Pro Rata Share of a Payment Amount within five (5) Business Days after notice from Administrative Agent, until such Lender cures such failure as permitted in this Agreement, and (b) a Lender that assigns any of its interest in the Loan in a manner that contradicts the terms for assignment set forth in the Loan Documents.”

(c)                                  The definition of “Target Monthly Amortization” in Exhibit B of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

“Target Monthly Amortization” means for any period, the hypothetical monthly payment of principal and interest which would be required for each month during such period if the Deemed Principal Balance was amortized in level payments of principal and interest over a thirty (30) year period at an interest rate per annum equal to the greater of (i) 7.5% per annum, and (ii) 2.75% plus the Treasury Rate.”

2.                                       EXTENSION OF MATURITY DATE. Hereinafter, the term “Maturity Date” and all other references to the maturity date of the Loan in the Note and the other Loan Documents shall mean November 15, 2011. The unpaid principal balance of the Loan, together with all accrued but unpaid interest thereon, shall be due and payable on the Maturity Date, as extended hereby. Borrower hereby renews, but does not extinguish, the Note and the liens, security interests and assignments created and evidenced by the Deed of Trust and the other

2

Loan Documents, and all of the Loan Documents are hereby renewed and modified by extending the maturity date thereof as set forth above.

3.                                       EXTENSION OPTIONS.   Section 1.12(c) of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

“(c) Borrower shall have one option to extend the Maturity Date of the Loan for a period of six (6) months (the “Extension Period”), at which time the term “Maturity Date” shall mean the Maturity Date, as extended pursuant to this Section 1.12. The exercise of each extension option shall be effective only if all of the following conditions have been satisfied as to each extension on or before the applicable Maturity Date:

(i)                                     The request for extension must be made to Administrative Agent in writing not more than one hundred twenty (120) days, and not less than sixty (60) days (unless such time period is shortened by Administrative Agent in its reasonable discretion), prior to the applicable Maturity Date.

(ii)                                  There shall then exist no Default or Potential Default on the applicable Maturity Date.

(iii)                               For the Extension Period to be granted, either the most current appraisal of the Property in the Administrative Agent’s possession (that complies with Section 2.13 of the Loan Agreement and has been approved by Administrative Agent) or, if required by Administrative Agent, an update of such appraisal prepared within the ninety (90) days preceding the existing Maturity Date, in form and substance satisfactory to Administrative Agent and otherwise in accordance with the appraisal requirements described in Section 2.13 below, shows that the Deemed Principal Balance is not greater than 70% of the as-is value of the Property.

(iv)                              The NOI for the Property, verified by Administrative Agent’s NOI Confirmation Letter after receipt of Borrower’s NOI Certificate, based on twelve (12) calendar months is not less than 100% of the Target Monthly Amortization for the Loan for such twelve-month period. In the event the NOI for the Property is less than 100% of the Target Monthly Amortization for the Loan, Borrower has the option on or prior to the initial Maturity Date to pay down the outstanding principal balance of the Loan without any prepayment charge or penalty to an amount (as reasonably determined by Administrative Agent) which, if such amount had been outstanding on the date of calculation required above, the NOI for the Property would not have been less than 100% of the Target Monthly Amortization for the Loan.

(v)                                 Administrative Agent shall have determined, in its commercially reasonable judgment, that no material adverse change has occurred with respect to the Project, or the financial condition or creditworthiness of Borrower or Guarantor.

3

(vi)                              On or before the Maturity Date, Borrower shall make a principal payment on the Loan, in addition to all other payments required to be made on the Loan, in the amount of $500,000.00.

(vii)                           Borrower shall cause to be delivered to Administrative Agent at Borrower’s expense an endorsement to the Title Insurance reflecting that the coverage afforded by the Title Insurance has not been adversely affected as a result of the modification and extension of the Loan and the documents referred to in paragraph (vii) below.

(viii)                        Borrower and Guarantor shall have executed and delivered to Administrative Agent a modification and extension agreement, providing for, among other things (1) the extension of the Maturity Date, (2) the reaffirmation by Borrower and Guarantor of their respective obligations under the Loan Documents, and (3) the waiver and release by Borrower and Guarantor of any defenses, claims, counterclaims, and rights of offset, if any, which Borrower or Guarantor may then have in respect of the Lenders and the Indebtedness and Obligations, together with such other agreements, documents or amendments to the Loan Documents as are reasonably requested by Administrative Agent to properly document the extension, all in form and content satisfactory to each of the Lenders in their good faith business judgment. During the Extension Period, unless noted above, all terms and conditions of the Loan Documents (including but not limited to interest rates and payments) pertaining to the Loan shall continue to apply.

(ix)                                Borrower shall have paid to Administrative Agent, for the ratable benefit of Lenders, as a condition to such extension on or before the first day of the applicable Extension Period, an extension fee of 0.175% of the then Deemed Principal Balance of the Loan as of the first day of each Extension Period.

If all of the foregoing conditions are not satisfied strictly in accordance with their terms, the extension shall not be or become effective. Upon the execution and delivery by Borrower, Guarantor and Administrative Agent of the modification and extension agreement referred to in subparagraph (vii) above, the extension shall be deemed to be effective. Whether or not the extension becomes effective, Borrower shall pay all out-of- pocket costs and expenses incurred by Administrative Agent in connection with the proposed extension (pre- and post-closing), including, without limitation, appraisal fees, environmental audit and legal fees; all such costs and expenses incurred up to the time of Administrative Agent’s written agreement to the extension shall be due and payable prior to Administrative Agent’s execution of that agreement (or if the proposed extension does not become effective, then upon demand by Administrative Agent).”

4.                                       PRINCIPAL PAYMENT.  Prior to the effectiveness of this Agreement, Borrower shall make a principal repayment on the Loan in the amount of $500,000.00 (the “Principal Payment”).

4

5.                                       LOAN AMOUNT; NO FURTHER ADVANCES. The amount of the Loan, following receipt of the Principal Payment, is hereby decreased to $62,268,359.73 and the amount of the Loan referenced in each Loan Document shall hereafter be $62,268,359.73. No further advances of the Loan shall be made to Borrower. The Deemed Principal Balance, following receipt of the Principal Payment, is $62,268,359.73.

6.                                       INTEREST RATE.   Section 1.7(a) of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

“(a)                            BBA LIBOR Daily Floating Rate. The unpaid principal balance of the Notes from day to day outstanding which is not past due, shall bear interest at a fluctuating rate of interest per annum (the “Floating Rate”) equal to the lesser of (i) the maximum non-usurious rate of interest allowed by applicable law or (ii) the greater of (A) the BBA LIBOR Daily Floating Rate plus four hundred (400) basis points per annum, and (B) six percent (6.00%). The “BBA LIBOR Daily Floating Rate” shall mean a fluctuating rate of interest per annum equal to the British Bankers Association LIBOR Rate (“BBA LIBOR”), as published by Reuters (or other commercially available source providing quotations of BBA LIBOR as selected by Administrative Agent from time to time) as determined for each Business Day at approximately 11:00 a.m. London time two (2) London Banking Days prior to the date in question, for U.S. Dollar deposits (for delivery on the first day of such interest period) with a one month term, as adjusted from time to time in Administrative Agent’s sole discretion for reserve requirements, deposit insurance assessment rates and other regulatory costs. A “London Banking Day” is a day on which banks in London are open for business and dealing in offshore dollars. Interest shall be computed for the actual number of days which have elapsed, on the basis of a 360-day year. The calculation of interest on this basis will result in a higher interest rate than it would if it were calculated based upon a three hundred sixty-five (365) or three hundred sixty-six (366) day period.”

7.                                       APPLICATION OF NOI.   Borrower covenants and agrees that, prior to the occurrence of a Default, in each month during the term of the Loan, the NOI (provided, that, for the purposes of this paragraph, in calculating NOI the adjustment required in items (i) and (iii) of the definition of Adjusted Expenses shall not be made, but the calculation will account for the accrual of the management fee for only one calendar month and at a rate not to exceed two and one half percent (2.50%)) for the immediately preceding month shall be applied in the following order:

(a)                             To payment of interest on the Loan pursuant to Section 1.12(a) of the Loan Agreement;

(b)                            To fund an operating reserve (the “Operating Reserve”) until the Operating Reserve equals $500,000 (the “Required Operating Reserve Amount”); and, thereafter, remaining NOI shall be used to fund the Operating Reserve to the extent necessary to maintain the Required Operating Reserve Amount; and

5

(c)          Until such time that the Target DSC is achieved, all remaining NOI (in the amount of NOI evidenced on the Excess Cash Flow Certificate most recently submitted to Administrative Agent) shall be delivered to Administrative Agent to be applied as a payment of principal on the Loan (the “Excess Cash Flow Payment”). As used herein, “Target DSC” means the achievement of NOI equal to 140% of the Target Monthly Amortization, with testing based on the prior twelve (12) month period.

Payments of interest and scheduled principal payments shall be made as required by this Agreement, and the application of remaining NOI as above required shall be made on the 25th day of each month. After the occurrence of a Default or a Potential Default, all NOI shall be applied against the Loan or in such other manner, as determined by the Lenders in their sole discretion.

8.             PRINCIPAL PAYMENTS.

(a)          In addition to Excess Cash Flow Payments, interest payments due pursuant to the terms of the Loan Documents, and any other payments required by the Loan Documents Borrower shall make principal payments in the amount of $375,000.00 on each of March 31, 2011, June 30, 2011, September 30, 2011, and December 30, 2011 (the December payment to be made to the extent that the Maturity Date is extended pursuant to Section 1.12(c) of the Loan Agreement) (each a “Quarterly Payment”). Once the Condominium Loan has been paid in full, any Release Payment (as defined in that certain Sixth Loan Modification and Extension Agreement executed as of March 15, 2011 among Condominium Borrower and the lenders party to the Condominium Loan) from the Condominium Loan shall be paid by Condominium Borrower to Administrative Agent and credited against the amount of the next Quarterly Payment.

(b)         From and after the date on which the Target DSC is achieved, Borrower shall, in lieu of Excess Cash Flow Payments but in addition to all interest payments on the Loan required by the Loan Documents, make monthly principal payments on the Loan on the first day of each month in an amount equal to the hypothetical monthly payment of principal if the Deemed Principal Balance was amortized in level monthly payments of principal and interest over a thirty (30) year period at an interest rate equal to the greater of (i) 7.5% per annum, and (ii) 2.75% plus the Treasury Rate. If, as of the end of each calendar quarter, the Property does not satisfy the Target DSC, Borrower shall immediately resume making monthly payments on the Loan in the amount of the Excess Cash Flow Payment until the first day of the month following the achievement of the Target DSC as tested at the end of a calendar quarter, at which time monthly payments shall re-commence as set forth in the first sentence of this Section 8(b).

9.             OPERATING RESERVE. The Operating Reserve shall be maintained in an account at Administrative Agent, which account shall be pledged as collateral for the Loan. Prior to the occurrence of a Default or Potential Default, Borrower shall be entitled to obtain disbursements from the Operating Reserve to pay operating expenses and capital expenses related to the Property and approved by Administrative Agent. In order to obtain each such disbursement, Borrower shall deliver to Administrative Agent five (5) business days written

6

notice of the requested disbursement, which notice shall contain the amount requested, a detailed description of the use of such funds, a calculation in detail reasonably satisfactory to Administrative Agent that an operating deficit exists with respect to operations of the Property in an amount equal to the requested disbursement, and such invoices, purchase orders or other information related to the amount of the requested disbursement as Administrative Agent shall reasonably require. Borrower shall only be entitled to a disbursement from the Operating Reserve in an amount reasonably approved by Administrative Agent and not more than once each calendar month. After the occurrence of a Default, Administrative Agent shall be entitled to apply any and all amounts in the Operating Reserve against the Loan as determined in its sole and absolute discretion. On or prior to the date of this Agreement, Borrower shall execute and deliver to Administrative Agent a Security Agreement (Deposit Account) (herein so called) in form and substance satisfactory to Administrative Agent granting a security interest in favor of the Lenders in the account used to establish the Operating Reserve.

10.           GUARANTY.
