(h)             The Authority shall have been furnished with an endorsement to the title insurance policy issued by Land Title Guarantee Company (the “Title Company”) disclosing no additional exceptions to title to the Property or Improvements and increasing the amount of the coverage equal to the amount of the advance requested plus the total of all prior advances and deleting the mechanic’s and materialmen’s lien exception with respect thereto.

(i)              Borrower shall be in compliance with all governmental regulations pertaining to the zoning, construction, maintenance and operation of the Improvements.

(j)              The Authority shall have inspected the work in place and determined that all Renovations completed to the date of the request for an advance have been performed in accordance with the Plans in a good and workmanlike manner and that the Renovations theretofore completed are of a value reasonably determined by the Authority to be not less than the amount theretofore disbursed, plus the amount requested. The Authority and its agents shall have the right of entry and free access to the Improvements during normal business hours and the right to inspect all work done, and materials, equipment and fixtures furnished, installed or stored in and about the Improvements and to inspect all books, contracts and records of the Borrower.

(k)             The Loan shall be and remain in balance. The Loan shall be deemed to be in balance only when the undisbursed proceeds of the Loan (after provision for reserves, fees, expenses and other deposits required by the Authority) equal or exceed the amount necessary (based on the Authority’s estimate of the cost to complete construction of the Renovations) to pay for all work completed and all materials delivered, for which payment has not been made, and the cost of completing the Renovations in accordance with the Plans.

(l)              Changes in the Plans, or changes by altering or adding to the work contemplated, or orders for extra work must have received the prior written approval of the Authority.

(a)             Except for the initial disbursement to be made by the Authority at closing of the Loan to fund the Borrower’s acquisition of the Property and Improvements, the Borrower shall make applications for disbursements of the Loan proceeds (each a “Draw Request”) in accordance with the Disbursement Agreement.

(b)             If, at any time a mechanic’s lien is filed against the Property and Improvements or a notice of intent to file a mechanic’s lien is filed which is not released or otherwise satisfied to the Authority’s satisfaction, or if the Borrower fails to comply with any of the other terms, conditions and provisions of this Agreement, or if the Authority determines, which determination shall be binding on Borrower, that the materials furnished or work performed do not comply with the Plans, or if the Authority determines that the work done at that particular stage of construction has not been done in a good and workmanlike manner, or if Borrower is in any way in default under the Loan Documents, the Authority may, at its option, refuse to make a disbursement pursuant to any Draw Request until such conditions have been remedied to the satisfaction of the Authority and may exercise its other rights and remedies under the Loan Documents.

(c)             If the Authority determines that the Loan is not in balance and there are insufficient undisbursed Loan proceeds to enable the Borrower to complete the construction of the Renovations, or make any other payments required herein or under the Loan Documents, including but not limited to the payment of all items described in paragraph (f) of this Section 5 (the “Other Costs”), or if there are insufficient funds in a line item, as shown on the Budget or Schedule of Values, then the Authority may refuse to make any further disbursements of Loan proceeds until Borrower shall have deposited with the Title Company an amount (the “Borrower’s Balancing Funds”) equal to the greater of: (i) the amount as determined and certified by a licensed architect, employed at Borrower’s expense and approved by the Authority, as the amount required to complete the Renovations in accordance with the Plans together with payment of the Other Costs; (ii) the amount of any subcontracts and/or firm quotations for the completion of any such work together with payment of the Other Costs; or (iii) an amount determined necessary by the Authority to bring the Loan in balance. The Borrower’s Balancing Funds

3

shall be deposited into an interest-bearing account established by the Title Company for the purpose of disbursing the Loan proceeds and shall for all purposes become a part of the Loan proceeds as provided herein and in the Disbursement Agreement and shall be disbursed first to fund Draw Requests prior to the disbursement of any further Loan proceeds. All Borrower’s Balancing Funds are hereby pledged to secure the Loan and in the event of default by Borrower under the Loan Documents, Borrower’s Balancing Funds may, at the option of Lender, be applied either to the completion of the Renovations or the amounts due to the Lender under the Loan Documents.

(d)             The Authority may, without the consent of the Borrower, but with prior notice to Borrower before disbursement, authorize the disbursement to itself from the Loan proceeds any sums payable to the Authority by the Borrower on account of recording costs, title insurance costs, loan fees, attorney fees, interest, loan extension fees, insurance, taxes and inspection fees all as provided for in the Loan Documents; provided, however, that Borrower may pay any of such items and upon furnishing receipt evidencing such payments, shall be entitled to reimbursement from the Loan proceeds, provided there are sufficient funds to complete the construction of the Renovations and such items are included in the Budget.

5.             Additional Conditions for Final Disbursement. In addition to the satisfaction of all other conditions for the disbursement of Loan proceeds, the final disbursement of Loan proceeds and retainage shall be subject to the following:

(a)             Receipt and approval by the Authority of a final certificate of occupancy or other evidence of the completion of construction and approval of the Improvements for occupancy from the applicable governmental authority.

(b)             Receipt and approval by the Authority of Certificates of completion from Borrower’s architect stating that the Renovations have been completed substantially in accordance with the Plans and all applicable requirements of governmental authorities and that an authorized representative of the party executing the certificate made such periodic inspections of the Renovations during the course of construction as it deemed necessary as the basis of such certification, and any other evidence reasonably required by Authority that the Renovations have been completed in compliance with all requirements of governmental authority.

(c)             Such final lien waivers, certificates and estoppels as the Authority or Title Company may reasonably require from Borrower’s architect, general contractor, and all other contractors, subcontractors and material suppliers retained by Borrower or Borrower’s general contractor or any subcontractor which have performed work on the Property or provided labor, materials or supplies in connection therewith certifying receipt of the final payment of all sums owing to each of such parties from Borrower with respect to the construction and stating that each such party has no claim against Borrower, the construction or any Loan funds arising out of or in connection with such work, labor, materials or supplies.

(d)             An affidavit and indemnity duly executed by Borrower stating that each person providing any material or performing any work in connection with the construction for Borrower, the general contractor and all subcontractors has been paid in full or will be paid in full from the proceeds of such advance, and that lien waivers have been received from all contractors, subcontractors and suppliers who have performed work or supplied materials in connection with the construction of the construction for Borrower, the general contractor and all subcontractors.

(e)             The Authority agrees that if upon final completion of the Renovations the total actual costs of the acquisition and renovation of the Property and Improvements is less than the amount estimated as of the execution of the Commitment and therefore the Borrower’s equity advanced at closing is more than the fifteen percent (15%) of such costs required in the Commitment, the Authority agrees to refund the amount of such excess equity to Borrower from the Loan proceeds, less any Cost of Funds Reimbursement due to the Authority pursuant to the Note if the final amount advanced under the Loan is less than $6,750,000.

6.             Commencement and Completion of Construction. Borrower shall commence the Renovations no later than sixty (60) days after the date hereof, but in no event prior to the satisfaction of the conditions to commencement of the Renovations set froth in Section 3 hereof, and shall prosecute the construction or rehabilitation with due diligence and shall complete the Renovations by no later than December 8, 2008 (the “Completion Date”), in strict compliance with the Plans and applicable rules and regulations and in a good and workmanlike manner.

(a)           Upon the occurrence of any Event of Default that is not cured as otherwise provided herein or in the other Loan Documents, and at any time thereafter, the Authority may, at its option, terminate this Agreement and shall be under no further obligation to make payments or disbursements hereunder or take any other action with respect to this Agreement. If the Authority so elects to terminate this Agreement, it may use and apply any undisbursed Loan proceeds together with any Borrower’s Balancing Funds, regardless of the purpose for which such funds were deposited, in such manner and for such purposes as it may determine. The Loan, with all accrued interest and other amounts payable hereunder, shall, at the option of the Authority, become immediately due and payable without presentment, demand, protest or other notice of any kind all of which are expressly waived by the Borrower. The Authority may proceed with every remedy available at law or equity or provided for herein or in any document executed in connection herewith, and all expenses incurred by the Authority and any assignee of the Authority in connection with any remedy shall be deemed indebtedness of the Borrower to the Authority or such assignee and a part of the Secured Obligations (as defined in the Deed of Trust).

7

The Authority may apply the proceeds from any collateral for the Loan or from any other source against any of the Secured Obligations as and in any order it sees fit.

(b)             If the Authority elects not to terminate this Agreement, it may enter into possession of the premises and perform any and all work and labor necessary to complete the Renovations substantially according to the Plans. All sums expended by the Authority to complete the Renovations shall be deemed to have been paid to the Borrower and secured by the Deed of Trust. For this purpose, the Borrower hereby constitutes and appoints the Authority its true and lawful attorney-in-fact, with full power of substitution in the premises, to complete the construction or rehabilitation of the Improvements in the name of the Borrower. The Borrower hereby empowers the Authority as follows: (i) to use any undisbursed Loan proceeds and Borrowers Balancing Funds, including any balance which may be held in escrow, for the purpose of completing the Renovations in the manner called for by the Plans; (ii) to make such additions, changes and corrections in the Plans as shall be necessary or desirable to complete the Renovations in substantially the manner contemplated by the Plans; (iii) to employ such contractors, subcontractors, agents, architects and inspectors as shall be required for said purposes; (iv) to pay, settle or compromise all existing bills and claims which may be liens against the mortgaged property, or as may be necessary or desirable for the completion of the Renovations, or for clearance of title; (v) to execute all applications and certificates in the name of the Borrower which may be required by any of the contract documents; (vi) to prosecute and defend all actions or proceedings in connection with the mortgaged premises or the Renovations and to take such action and require such performance as it deems necessary under the accepted guaranty of completion; and (vii) to do any and every act which the Borrower might do in its own behalf. It is further understood and agreed that this power of attorney, which shall be deemed to be a power coupled with an interest, cannot be revoked. The Borrower hereby assigns and quit claims to the Authority all Loan proceeds unadvanced under the Note and all Borrower’s Balancing Funds for use in completing the Renovations, such assignment to become effective only in case of the Borrower’s uncured default.

(c)             No delay or failure of the Authority in the exercise of any right or remedy provided for hereunder shall be deemed a waiver of the right by the Authority and no exercise or partial exercise or waiver of any right or remedy shall be deemed a waiver of any further exercise of such right or remedy or of any other right or remedy that the Authority may have. The enforcement of any rights of the Authority as to any security for the Loan shall not affect the rights of the Authority to enforce payment of the Loan and to recover judgment for any portion thereof remaining unpaid. The rights and remedies herein expressed are cumulative and not exclusive of any right or remedy that the Authority shall otherwise have.

10.           Rights of the Authority. The Authority may assign, negotiate, pledge or otherwise hypothecate this Agreement, the Note and the Loan Documents or any of its rights and security hereunder or thereunder, in whole or in part.

11.           Miscellaneous Provisions.

(a)             Based upon periodic physical inspections, the documentation for Loan advances, and upon information supplied by the Contractor, the Borrower shall monitor progress of construction under the Construction Contract and under each subcontract and shall make a monthly assessment as to the possibility that there may be cost overruns in connection with such contract or subcontracts. The Borrower shall promptly notify the Authority of any such potential cost overruns.

(b)             Borrower shall be liable to the Authority for all sums paid or incurred in excess of the amount of the Loan for the completion of the Renovations, whether the same shall be paid or incurred pursuant to provisions of this Agreement or the other Loan Documents, or otherwise and for all accrued interest.

8

paid by Borrower to the Authority upon demand with interest at the default rate set forth in the Note to the date of payment to the Authority and all of the foregoing, including interest, shall be deemed and shall constitute advances under this Agreement.

(c)             Any obligation of the Authority to make advances hereunder is imposed solely and exclusively for the benefit of Borrower and no other person, firm or corporation shall, under any circumstances, be deemed to be a beneficiary of such condition, nor shall it have any derivative claim against the Authority.

(d)             Neither this Agreement nor any provision hereof may be changed, waived, discharged, or terminated orally and may only be modified or amended by an instrument in writing, signed by the parties hereto.

(e)             Inspections and approval of the Plans, the Renovations, the Improvements and the workmanship and materials used therein impose no responsibility or liability of any nature or kind whatsoever on the Authority to Borrower and/or any third parties.

(f)              All rights, powers, and remedies herein given to the Authority are cumulative and not alternative, and are in addition to all other statutes or rules of law. Any forbearance or delay by the Authority in exercising the same shall not be deemed to be a waiver thereof and the exercise of any right or partial exercise thereof shall not preclude the further exercise thereof and the same shall continue in full force and effect until specifically waived by an instrument in writing executed by the Authority. All representations, warranties and covenants by Borrower shall survive the making of the advances of the Loan and the provisions hereof shall be binding upon Borrower, its successors and assigns and inure to the benefit of the Authority, its successors and assigns.

(h)             Borrower agrees that, in the event there is any conflict between the terms and conditions of this Agreement and the Note and Deed of Trust, the Note and Deed of Trust shall prevail.

(i)              All notices required under this Agreement shall be in writing and shall be deemed to have been sufficiently given or served when presented personally or when deposited in the United States mail, by registered or certified mail, addressed to the parties at the address set forth in the Deed of Trust. Such addresses may be changed by notice to the other party given in the same manner as provided in the Deed of Trust.
