               (i) comprehensive all risk insurance on the Improvements and the Personal Property, including contingent liability from Operation of Building Laws, Demolition Costs and Increased Cost of Construction Endorsements, in each case (A) in an amount equal to 100% of the “Full Replacement Cost,” which for purposes of this Security Instrument shall mean actual replacement value (exclusive of costs of excavations, foundations, underground utilities and footings) with a waiver of depreciation, (B) containing an agreed amount endorsement with respect to the Improvements and Personal Property waiving all co-insurance provisions; and (C) providing for no deductible in excess of $250,000;

               (ii) commercial general liability insurance against claims for personal injury, bodily injury, death or property damage occurring upon, in or about the Property, such insurance (A) to be on the so-called “occurrence” form with a combined single limit of not less than $2,000,000; and (B) to cover at least the following hazards: (1) premises and operations; (2) products and completed operations on an “if any” basis; (3) independent contractors; and (4) blanket contractual liability for all written and oral contracts;

               (vii) such other insurance as may be required pursuant to the terms of the Indenture.

          (b) All insurance provided for in Subsection 3.3 (a) hereof shall be obtained under valid and enforceable policies (the “Policies” or in the singular, the “Policy”), in such forms and as may be reasonably satisfactory to Beneficiary, issued by financially sound and responsible insurance companies authorized to do business in the state in which the Property is located and approved by Beneficiary. The insurance companies must have a general policy rating of A or better and a financial class of VI or better by A.M. Best Company, Inc.. Not less than thirty (30) days prior to the expiration dates of the Policies theretofore furnished to Beneficiary pursuant to Subsection 3.3(a), certified copies of the Policies (or certificates evidencing the coverage afforded thereby) marked “premium paid” or accompanied by evidence reasonably satisfactory to Beneficiary of payment of the premiums due thereunder (the “Insurance Premiums”), shall be delivered by Grantor to Beneficiary.

          (c) Grantor shall not obtain (i) any umbrella or blanket liability or casualty Policy unless Beneficiary’s interest is included therein as provided in this Security Instrument and such Policy is issued by a Qualified Insurer, or (ii) separate insurance concurrent in form or contributing in the event of loss with that required in Subsection 3.3(a) to be furnished by, or which may be reasonably required to be furnished by, Grantor. In the event Grantor obtains separate insurance or an umbrella or a blanket Policy, Grantor shall notify Beneficiary of the same and shall cause certified copies of each Policy (or certificates evidencing the coverage afforded thereby) to be delivered as required in Subsection 3.3(a). Any blanket insurance Policy shall specifically allocate to the Property the amount of coverage from time to time required hereunder and shall otherwise provide the same protection as would a separate Policy insuring only the Property in compliance with the provisions of Subsection 3.3(a).

          (d) All Policies of insurance provided for or contemplated by Subsection 3.3(a), except for the Policy referenced in Subsection 3.3(a)(v), shall name Beneficiary and

Grantor as the insured or additional insured, as their respective interests may appear, and in the case of property damage, boiler and machinery, and flood insurance, shall contain a so-called New York standard non-contributing mortgagee clause in favor of Beneficiary providing that the loss thereunder shall be payable to Beneficiary.

          (e) All Policies of insurance provided for in Subsection 3.3(a) shall contain clauses or endorsements to the effect that:

               (i) the Policy shall not be materially changed (other than to increase the coverage provided thereby) or cancelled without at least 30 days’ written notice to Beneficiary; and

               (ii) each Policy shall provide that the issuers thereof shall give written notice to Beneficiary if the Policy has not been renewed thirty (30) days prior to its expiration.

          (f) If at any time Beneficiary is in receipt of written evidence that all insurance required hereunder is not in full force and effect, Beneficiary shall have the right, without notice to Grantor to obtain such insurance coverage as is required hereunder, and all expenses incurred by Beneficiary in connection with such action or in obtaining such insurance and keeping it in effect shall be paid by Grantor to Beneficiary upon demand.

          (g) If the Property shall be damaged or destroyed, in whole or in part, by fire or other casualty, Grantor shall give prompt notice of such damage to Beneficiary and, at the election of Grantor, either redeem Notes in the principal amount equal to the Net Proceeds payable in connection with such fire or other casualty, or shall promptly commence and diligently prosecute the completion of the repair and restoration of the Property as nearly as possible to the condition the Property was in immediately prior to such fire or other casualty, with such alterations as may be reasonably approved by Beneficiary (the “Restoration”) and otherwise in accordance with Section 4.2 of this Security Instrument; it being understood, however, that if Grantor elects to restore the Property, Grantor shall not be obligated to restore the Property to the precise condition of the Property prior to any casualty or other damage or injury to the Property if the restoration or repair to be performed shall have no material effect on the fair market value of the Property as compared to the fair market value of the Property if the same had been restored or repaired to its precise condition immediately prior to such taking or casualty. If Grantor elects to restore the Property, Grantor shall pay all costs of such Restoration whether or not such costs are covered by insurance.

     3.4 Payment of Taxes, etc.

          (a) Subject to Grantor’s rights to contest the same as provided below, Grantor shall pay all taxes, assessments, water rates, sewer rents, governmental impositions, and other charges, including without limitation vault charges and license fees for the use of vaults, chutes and similar areas adjoining the Land, now or hereafter levied or assessed or imposed against the Property or any part thereof (the “Taxes”), all ground rents, maintenance charges and similar charges, now or hereafter levied or assessed or imposed against the Property or any part thereof (the “Other Charges”), and all charges for utility services provided to the Property prior to the date the same would become delinquent. Grantor will deliver to Beneficiary, within ten (10)

days of a request by Beneficiary’s, evidence reasonably satisfactory to Beneficiary that the Taxes, Other Charges and utility service charges have been so paid, are not then delinquent or are being contested. Upon request of Beneficiary, Grantor shall furnish to Beneficiary paid receipts for the payment of the Taxes and Other Charges prior to the date the same shall become delinquent, unless the same are being contested in accordance with the terms hereof.

          (b) After prior written notice to Beneficiary, Grantor, at its own expense, may contest by appropriate legal proceeding, promptly initiated and conducted in good faith and with due diligence, the amount or validity or application in whole or in part of any of the Taxes or Other Charges, provided that (i) no Event of Default (as defined in Article 9) has occurred and is continuing, (ii) Grantor is permitted to do so under the provisions of any other mortgage, deed of trust or deed to secure debt affecting the Property, (iii) such proceeding shall suspend the collection of the Taxes from Grantor and from the Property or Grantor shall have paid all of the Taxes under protest, (iv) such proceeding shall be permitted under and be conducted in accordance with the provisions of any other instrument to which Grantor is subject and shall not constitute a default thereunder, and (v) neither the Property nor any part thereof or interest therein will be in danger of being sold, forfeited, terminated, cancelled or lost.

     3.5 Condemnation. Grantor, within ten (10) days of becoming aware of the institution of the actual or threatened commencement of any condemnation or eminent domain proceeding, shall notify Beneficiary of the pendency of such proceedings, and shall deliver to Beneficiary copies of any and all papers served in connection with such proceedings. Notwithstanding any taking by any public or quasi-public authority through eminent domain or otherwise, the Debt shall not be reduced until any award or payment therefor shall have been actually received and applied by Beneficiary, after the deduction of expenses of collection, to the reduction or discharge of the Debt. If the Property or any portion thereof is taken by a condemning authority, Grantor shall, at its option, either redeem Notes in the principal amount equal to the Net Proceeds (as defined in Section 4.2(b)) payable in connection with such condemnation, or promptly commence and diligently prosecute the restoration of the Property in accordance with, and otherwise comply with the provisions of, Section 4.2. If the Property is sold, through foreclosure or otherwise, prior to the receipt by Beneficiary of the award or payment, Beneficiary shall have the right, whether or not a deficiency judgment on the Indenture shall have been sought, recovered or denied, to receive the award or payment, or a portion thereof sufficient to redeem the Notes and repay and other outstanding Debt.

     3.6 Leases and Rents. No future Lease shall be executed without Beneficiary’s approval, which shall not be unreasonably withheld. Upon request, Grantor shall furnish Beneficiary with executed copies of all Leases. All future Leases shall provide that they are subordinate to this Security Instrument and that the lessee shall attorn to the Beneficiary, and by acceptance of this Security Instrument, Beneficiary agrees to enter into a customary non-disturbance agreement with the tenant under any such future Lease, which agreement shall be in form and substance reasonably satisfactory to Beneficiary.

     3.7 Maintenance of Property. Grantor shall cause the Property to be maintained in a good and safe condition and repair, reasonable wear and tear excepted. The Improvements shall not be removed or demolished without the consent of Beneficiary. Grantor shall, in accordance with prudent business practices, repair, replace or rebuild any part of the Property which may be

destroyed by any casualty, or become damaged, worn or dilapidated, or which may be affected by any proceeding of the character referred to in Section 3.5 hereof, and shall complete and pay for any structure at any time in the process of construction or repair on the Land.

     3.8 Waste. Grantor shall not commit or suffer any waste of the Property or make any change in the use of the Property which will in any way materially increase the risk of fire or other hazard arising out of the operation of the Property, or take any action that might invalidate or give cause for cancellation of any Policy.

     3.9 Compliance With Laws. Grantor shall comply in all material respects with all existing and future federal, state and local laws, orders, ordinances, governmental rules and regulations or court orders affecting or which may be interpreted to affect the Property, or the use thereof (“Applicable Laws”).

     3.10 Liens. Grantor will never permit to be created or exist in respect of the Property or any part thereof any lien or security interest other than the liens or security interests hereof and other than Permitted Exceptions (as defined in Section 5.1).

Beneficiary shall have the use of the plans and specifications and all permits, licenses and approvals required or obtained in connection with the Material Restoration. The identity of the contractors, subcontractors and materialmen engaged in any Material Restoration, as well as the contracts under which they have been engaged, shall be subject to prior review and acceptance by Beneficiary and the Casualty Consultant, not to be unreasonably withheld, conditioned or delayed. All costs and expenses incurred by Beneficiary in connection with making the Net Proceeds available for the Restoration including, without limitation, reasonable counsel fees and disbursements and the Casualty Consultant’s fees, shall be paid by Grantor.

               (iv) In no event shall Beneficiary be obligated to make disbursements of the Net Proceeds in excess of an amount equal to the costs actually incurred from time to time for work in place as part of the Restoration, as certified by the Casualty Consultant, minus, at the option of Beneficiary, the Casualty Retainage. The term “Casualty Retainage” as used in this Subsection 4.2(b) shall mean an amount equal to 10% of the costs actually incurred for work in place as part of the Restoration, as certified by the Casualty Consultant, until such time as the Casualty Consultant certifies to Beneficiary that Net Proceeds representing 50% of the required Restoration have been disbursed. There shall be no Casualty Retainage with respect to costs actually incurred by Grantor for work in place in completing the last 50% of the required Restoration. The Casualty Retainage shall in no event, and notwithstanding anything to the contrary set forth above in this Subsection 4.2(b), be less than the amount actually held back by Grantor from contractors, subcontractors and materialmen engaged in the Restoration. The Casualty Retainage shall not be released until the Casualty Consultant certifies to Beneficiary that the Restoration has been completed in accordance with the provisions of this Subsection 4.2(b) and that all approvals necessary for the re-occupancy and use of the Property have been obtained from all appropriate governmental and quasi-governmental authorities, and Beneficiary receives evidence reasonably satisfactory to Beneficiary that the costs of the Restoration have been paid in full or will be paid in full out of the Casualty Retainage, provided, however, that Beneficiary will release the portion of the Casualty Retainage being held with respect to any contractor, subcontractor or materialman engaged in the Restoration as of the date upon which the Casualty Consultant certifies to Beneficiary that the contractor, subcontractor or materialman has satisfactorily completed all work and has supplied all materials in accordance with the provisions of the contractor’s, subcontractor’s or materialman’s contract, and the contractor,

subcontractor or materialman delivers the lien waivers and evidence of payment in full of all sums due to the contractor, subcontractor or materialman as may be reasonably requested by Beneficiary or by the title company insuring the lien of this Security Instrument.

               (v) Beneficiary shall not be obligated to make disbursements of the Net Proceeds more frequently than once every calendar month.

               (vi) The excess, if any, of the Net Proceeds deposited with Beneficiary after the Casualty Consultant certifies to Beneficiary that the Restoration has been completed in accordance with the provisions of this Subsection 4.2(b), and the receipt by Beneficiary of evidence satisfactory to Beneficiary that all costs incurred in connection with the Restoration have been paid in full, shall be remitted by Beneficiary to Grantor, provided no Event of Default shall have occurred and shall be continuing.

          (c) All Net Proceeds not required (i) to be made available for the Restoration or (ii) to be returned to Grantor as excess Net Proceeds pursuant to Subsection 4.2(b)(vi) may be retained and applied by Beneficiary toward redemption of the Notes, whether or not then due and payable in such order, priority and proportions as Beneficiary in its discretion shall deem proper or, at the discretion of Beneficiary, the same may be paid, either in whole or in part, to Grantor for such purposes as Beneficiary shall designate, in its discretion. If Beneficiary shall receive and retain Net Proceeds, the lien of this Security Instrument shall be reduced only by the amount thereof received and retained by Beneficiary and actually applied by Beneficiary in redemption of the Notes and repayment of any other outstanding Debt.

          (c) The rights of Beneficiary or Trustee under this Security Instrument shall be separate, distinct and cumulative and none shall be given effect to the exclusion of the others.

     10.7 Right to Release Any Portion of the Property. Beneficiary may release any portion of the Property for such consideration as Beneficiary may require without, as to the remainder of the Property, in any way impairing or affecting the lien or priority of this Security Instrument, or improving the position of any subordinate lienholder with respect thereto, except to the extent that the obligations hereunder shall have been reduced by the actual monetary consideration, if any, received by Beneficiary for such release, and may accept by assignment, pledge or otherwise any other property in place thereof as Beneficiary may require without being accountable for so doing to any other lienholder. This Security Instrument shall continue as a lien and security interest in the remaining portion of the Property.
