Section 2.2 Principal and Interest.

2.2.1 Principal and Interest.

(a) Subject to Section 2.2.2, from the date hereof to but excluding the respective Maturity Dates with respect to each of the Notes, Borrower shall pay interest on the outstanding principal balance of the Notes at the Interest Rate.

Notwithstanding anything to the contrary in this Agreement and to the extent permitted by applicable law, if the aggregate amount of interest payable in respect of any Note pursuant to this Section 2.2 and all other consideration which would constitute interest for any period under applicable law with respect to such Note results in an effective rate of interest for such period on such Note in excess of the maximum rate permitted by law (after giving effect to any adjustment permitted by law to the interest rate paid or payable in any periods other than such period), the effective rate of interest for such period for such Note shall be limited to a rate of interest which would not cause the effective rate to exceed the maximum legal rate and, if any principal remains outstanding with respect to the other Note, the effective interest rate for the other Note shall be increased in a manner such that the aggregate payment of interest due on the Notes after such adjustments shall be equal to the aggregate interest payment due on the Notes had no adjustment been necessary, but in no event shall such increase in the effective interest rate for such other Note exceed the maximum legal rate applicable to such Note.

(b) Commencing with the Payment Date on May 11, 1998, and on each and every Payment Date thereafter through but excluding the Stated Maturity Date with respect to each Note, the principal amount of each Note and interest thereon at the Fixed Rate shall be payable in monthly installments of (i) principal with respect to each Note based on the amortization schedule as set forth in the applicable Note, and (ii) interest at the Fixed Rate as computed in accordance with Section 2.5.2 (the aggregate of such amounts with respect to the Notes, the “Monthly Debt Service Payment Amount”). Unless otherwise elected by Lender, such payments shall be applied first to the payment of interest with respect to the Notes with the remainder of such payment being applied to the reduction of the outstanding principal balance of the Notes.

(c) From and after the Anticipated Prepayment Date, interest on the Tranche A Note shall accrue at the Revised Interest Rate and shall be payable as provided in Sections 2.2.2 and 9.4.2.

2.2.2 Accrued Interest. Each monthly payment of principal and interest under the Tranche A Note made by Borrower thereunder on and after the Anticipated Prepayment Date shall be applied first to the payment of interest computed at the Fixed Rate with the remainder of such payment being applied to the reduction of the outstanding principal balance of the Tranche A Note. All Accrued Interest accruing in respect of the Tranche A Note shall be deferred, be added to the principal balance of the Tranche A Note and, to the extent permitted by applicable law, accrue interest at the Revised Interest Rate. All Accrued Interest shall be due and payable on the Maturity Date with respect to the Tranche A Note.

2.2.3 Default Rate. If an Event of Default shall have occurred and is continuing, Borrower shall pay interest at the Default Rate on the outstanding principal amount

- 26 -

of the Notes and due but unpaid interest thereon, upon demand from time to time (which interest is payable both before and after Lender has obtained a judgment with respect to the Loan), to the extent permitted by applicable law. Payment or acceptance of the increased rates provided for in this subsection is not a permitted alternative to timely payment or full performance by Borrower and, shall not constitute a waiver of any Default or Event of Default or an amendment to this Agreement or any other Loan Document and shall not otherwise prejudice or limit any rights or remedies of Lender.

Section 2.3 Loan Repayment and Defeasance.

2.3.1 Repayment. (a) Borrower shall repay any outstanding principal indebtedness of each Note in full on the Maturity Date with respect to each Note, together with all accrued and unpaid interest thereon to (but excluding) the date of repayment.

(b) Other than as set forth in Section 2.3.3 below, or as required or permitted pursuant hereto in connection with a Casualty or Condemnation, Borrower shall have no right to prepay all or any portion of the Loan during the period commencing on the Closing Date to but not including the Anticipated Prepayment Date; provided, however, that Borrower shall have the right to prepay the Tranche A Note in full, without penalty or premium, on the Payment Date occurring immediately prior to the Anticipated Prepayment Date in accordance with the remaining provisions of this Section 2.3.1(b). From and after the Anticipated Prepayment Date, the Tranche A Note may be prepaid in whole or in part, on any Payment Date, together with accrued interest to the date of such prepayment on the principal amount prepaid, without penalty or premium. Any such prepayment, shall be subject, in each case, to the satisfaction of the condition precedent that Borrower shall provide not less than five (5) Business Days’ prior written notice to Lender specifying the Payment Date on which such prepayment is to occur and indicating the principal amount of the Tranche A Note to be so prepaid.

2.3.2 Voluntary Defeasance of the Notes. (a) On or after the Optional Defeasance Date and subject to a Rating Confirmation having been obtained therefor and subject to the terms and conditions set forth in this Section 2.3.2, Borrower may defease all or any portion of either Note (hereinafter, a “Defeasance”). No Defeasance shall be permitted on or after the Anticipated Prepayment Date. Each Defeasance shall be subject, in each case, to the satisfaction of the following conditions precedent:

(i) Borrower shall provide not less than thirty (30) days’ prior written notice to Lender specifying a date (the “Defeasance Date”) on which the Defeasance is to occur. Such notice shall indicate whether both Notes or only one Note is to be defeased, whether such Defeasance will be partial or total, and if partial, the principal amount of the Notes or such Note to be defeased.

(ii) Borrower shall pay to Lender all accrued and unpaid interest on the principal balance of the Note or Notes to be defeased to but not including the Defeasance Date (and if the Defeasance Date is not a Payment Date, the Defeasance Deposit shall take into account the interest that would have accrued on such Note or Notes to but not including the next Payment Date).

- 27 -

(iii) Borrower shall pay to Lender all other sums, not including scheduled interest or principal payments, then due under such Note or Notes, this Agreement, the Mortgage and the other applicable Loan Documents (including, without limitation, in the event that an Event of Default shall then exist, all unpaid interest payable at the Default Rate and all sums expended by Lender in connection with such Event of Default).

(iv) If an Event of Default shall then exist, then the Defeasance must serve to cure such Event of Default and notwithstanding anything to the contrary contained herein, such Defeasance must be a total Defeasance.

(v) Borrower shall pay to Lender the required Defeasance Deposit for the Defeasance.

(vi) In the event only a portion of a Note or a portion of each Note is the subject of the Defeasance, Borrower shall execute and deliver all necessary documents to amend and restate such Note or Notes and issue two substitute notes for each such Note: one note having a principal balance equal to the defeased portion of such original Note (the “Defeased Note”) and one note having a principal balance equal to the undefeased portion of such original Note (the “Undefeased Note”). The Defeased Note and Undefeased Note shall have identical terms as such original Note (and the Defeased Note shall be cross-defaulted with the Undefeased Note), except for the principal balance. A Defeased Note cannot be the subject of any further Defeasance. An Undefeased Note may be the subject of a further Defeasance in accordance with the terms of this clause (vi) (the term “Note”, as used above in this clause (vi) for these purposes, being deemed to refer to the Undefeased Note that is the subject of the further defeasance) and the other provisions of this Section 2.3.2.

(vii) Borrower shall execute and deliver one or more security agreements, in form and substance reasonably satisfactory to Lender, creating a first priority lien on the Defeasance Deposit and the U.S. Government Securities purchased with the Defeasance Deposit in accordance with the provisions of this Section 2.3.2 (the “Security Agreement”).

(viii) Borrower shall deliver to Lender an opinion of counsel for Borrower in form reasonably satisfactory to Lender, which opinion may be based on reasonable assumptions, representations and warranties of Borrower, stating, among other things, that Lender has a perfected security interest in the U.S. Government Securities purchased with the Defeasance Deposit.

(ix) If required by the applicable Rating Agencies, Borrower shall also deliver or cause to be delivered a non-consolidation opinion with respect to the Successor Borrower, if any, in form and substance satisfactory to the applicable Rating Agencies and reasonably satisfactory to Lender (it being understood and agreed that if such opinion is acceptable to the Rating Agencies, Lender will be deemed to have approved such opinion). In addition, if the Loan is included in any REMIC formed pursuant to a Securitization, Borrower shall also deliver or cause to be delivered an opinion of counsel,

- 28 -

in form and substance reasonably satisfactory to Lender, stating that, after a Defeasance, the Loan will continue to be a “qualified mortgage” within the meaning of Section 860G of the Code and the REMIC will not fail to maintain its status as a “real estate mortgage investment conduit” within the meaning of Section 860D of the Code as a result of such Defeasance.

(x) Borrower shall deliver to Lender an Officer’s Certificate certifying that the requirements set forth in this Section 2.3.2(a) have been satisfied.

(xi) Borrower shall deliver such other certificates, documents or instruments as Lender may reasonably request.

(b) In connection with each Defeasance of all or any portion of any Note, Borrower hereby appoints Lender as its agent and attorney-in-fact for the purpose of using the Defeasance Deposit to purchase U.S. Government Securities (which purchases, if made by Lender, shall be made on an arm’s-length basis at then prevailing market rates) which provide payments on or prior to, but as close as possible to, all successive Payment Dates after the Defeasance Date, in the case of a Defeasance for the entire outstanding principal balance of the Notes, or the Defeased Note or Notes, in the case of a Defeasance for only a portion of the outstanding principal balance of a Note or the Notes, as applicable (including the outstanding principal balance of either the Loan or the Defeased Note or Notes on the Anticipated Prepayment Date), and in amounts equal to the Debt Service due on such dates under the Note or Notes or the Defeased Note or Notes, as applicable (the “Scheduled Defeasance Payments”). Borrower, pursuant to the Security Agreement or other appropriate document, shall irrevocably authorize and direct that the payments received from the U.S. Government Securities may be made directly to Lender and applied to satisfy the obligations of Borrower under the Note or Notes or the Defeased Note or Notes, as applicable. In connection with any total Defeasance of the Loan, any portion of the Defeasance Deposit in excess of the amount necessary to purchase the U.S. Government Securities required by this Section 2.3.2(b) and satisfy Borrower’s obligations under Section 2.3 shall be remitted to Borrower. In connection with any partial Defeasance of the Loan, any portion of the Defeasance Deposit in excess of the amount necessary to purchase the U.S. Government Securities required by this Section 2.3.2(b) and satisfy Borrower’s obligations under Section 2.3 shall be retained by Lender in an Eligible Account as additional collateral for the Loan, and shall be invested in Permitted Investments, Borrower hereby granting to Lender a security interest in such account and in such Permitted

Investments.

Borrower shall not be obligated to pay a Yield Maintenance Payment in addition to the Defeasance Deposit in connection with any Defeasance.

(c) In connection with a Defeasance under this Section 2.3.2 of the total aggregate outstanding principal amount of the Notes, Lender shall establish or designate one or more successor entities (the “Successor Borrower”) and Borrower shall transfer and assign all obligations, rights and duties under and to the Notes, together with the pledged U.S. Government Securities, to the Successor Borrower. The obligation of Lender to establish or designate a Successor Borrower shall be retained by the original Lender named herein notwithstanding the sale or transfer of this Agreement unless such obligation is specifically assumed by the transferee. The Successor Borrower shall assume the obligations hereunder and under the Notes (including all Defeased Notes) and the Security Agreement and, notwithstanding anything to the contrary contained in any Loan Document, the representations, warranties and covenants of the Loan Documents pertaining to the Property and the provisions of Section 6.1(i) hereof shall be of no further force or effect other than (i) Sections 11.13, 11.21 and 11.24 of this Agreement, (ii) the Environmental Indemnity, which shall terminate in accordance with its terms, and (iii) the Cooperation Agreement, which shall terminate in accordance with its terms.

2.3.3 Repayment Upon Default. If all or any part of the principal amount of the Notes is prepaid upon acceleration of the Loan following the occurrence of an Event of Default prior to the Anticipated Prepayment Date, then, in addition to such principal payment, Borrower shall be required to make such payments (the “Yield Maintenance Payments”) in an amount equal to the excess, if any, of (i) the sum of (A) the aggregate respective present values of all scheduled interest payments payable on each Payment Date in respect of the Notes (or the portion of all such interest payments corresponding to the portion of the principal of the Notes to be prepaid upon acceleration) for the period from the date of such prepayment upon acceleration to the Stated Maturity Date with respect to each Note, discounted monthly at a rate equal to the Treasury Constant Yield with respect to each Note and based on a 360-day year of twelve 30-day months and (B) the aggregate respective present values of all scheduled principal payments payable on each Payment Date in respect of the Notes (or the then unpaid portion thereof to be prepaid upon acceleration) assuming the then outstanding principal balance of the Notes is paid in full on the Stated Maturity Date with respect to each Note, discounted monthly at a rate equal to the Treasury Constant Yield with respect to each Note and based on a 360-day year of twelve 30-day months over (ii) the then current outstanding principal amount of the Notes (or the then unpaid portion thereof to be prepaid upon acceleration). If the Yield Maintenance Payments as calculated pursuant to this Section 2.3.3 would not be a positive number, the Yield Maintenance Payments shall be zero. The Yield Maintenance Payments, if any, to be paid in connection with any prepayment under this Section 2.3.3 shall be determined by Lender and written notice of the respective amounts and calculations thereof shall be furnished to Borrower by Lender promptly

- 30 -

after the acceleration. For purposes of this Section 2.3.3, the amount of the Notes (or the portion of the principal of the Notes to be prepaid upon acceleration) on the date of prepayment shall be determined after giving effect to any payment of scheduled amortization made on such date.

Section 2.4 Release of Property. No repayment, prepayment or Defeasance of all or any portion of the Loan shall cause, give rise to a right to require, or otherwise result in, the release of the Property from the lien of the Mortgage, except as set forth in Sections 2.4.1 and 2.4.2.

2.4.1 Total Defeasance. (a) If Borrower has elected to defease the Notes in their entirety, and the requirements of Section 2.3.2 have been satisfied, the Property shall be released from the lien of the Mortgage, and the U.S. Government Securities, pledged pursuant to the Security Agreement, shall be the sole source of collateral securing the Notes.

(b) In connection with the release contemplated in Section 2.4.1(a), Borrower shall submit to Lender, not less than ten (10) days prior to the Defeasance Date, a satisfaction of mortgage (for execution by Lender) in a form appropriate for recording in the Commonwealth of Pennsylvania and otherwise satisfactory to Lender in its reasonable discretion and all other documentation Lender reasonably requires to be delivered by Borrower in connection with such release (collectively, “Release Instruments”), together with an Officer’s Certificate certifying that such Release Instruments (i) are in compliance with all Legal Requirements, and (ii) will effect such release in accordance with the terms of this Agreement.

In addition to the rights of Borrower to have informational computer access to the accounts maintained hereunder in accordance with Section 9.1, Lender shall, upon the written request of Borrower, not more often than monthly, provide such information as it has in its possession regarding the records maintained in accordance with the first sentence hereof and information regarding funds on deposit in the Deposit Account.

- 36 -

and authority to own its properties and to transact the businesses in which it is now engaged. It is duly qualified to do business and is in good standing in each jurisdiction where it is required to be so qualified in connection with its properties, businesses and operations. It possesses all rights, licenses, permits and authorizations, governmental or otherwise, necessary to entitle it to own its properties and to transact the businesses in which it is now engaged (except where the failure to possess such rights, licenses, permits or authorizations would not have a Material Adverse Effect), and its sole business has been and is the ownership, management and operation of the Property.

(b) Proceedings. It has taken all necessary action to authorize the execution, delivery and performance of this Agreement and the other Loan Documents to which it is a party. This Agreement and such other Loan Documents have been duly executed and delivered by it and constitute legal, valid and binding obligations of Borrower enforceable against Borrower in accordance with their respective terms, subject to applicable bankruptcy, insolvency and similar laws affecting rights of creditors generally and general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) without offset, defense or counterclaim.

(c) No Conflicts. The execution, delivery and performance of this Agreement and the other Loan Documents by it will not conflict in any material respect with or result in a material breach of any of the terms or provisions of, or constitute a material default under, or result in the creation or imposition of any lien, charge or encumbrance (other than pursuant to the Loan Documents) upon any of its properties or assets pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, partnership agreement, management agreement or other Material Agreement to which it is a party or to which any of its properties or assets is subject, nor will such action result in any violation of the provisions of any statute or any order, rule or regulation applicable to it of any court or governmental agency or body having jurisdiction over it or any of its properties or assets, and any consent, approval, authorization, order, registration or qualification of or with any court or any such regulatory authority or other governmental agency or body or any other Person required for the execution, delivery and performance by it of this Agreement or any other Loan Documents to which it is a party or required for the consummation of the Bankruptcy Plan has been obtained and is in full force and effect in all material respects.

There are no actions, suits or proceedings at law or in equity by or before any Governmental Authority or other agency now commenced and to its Actual Knowledge there are no such actions, suits or proceedings threatened against or affecting it or the Property, which actions, suits or proceedings, alone or in the aggregate, if adversely determined, are reasonably likely to have a Material Adverse Effect.

(e) Agreements. It is not a party to any Material Agreement (excluding any Loan Document) which is reasonably likely to have a Material Adverse Effect. It is not in default (including, without limitation, by reason of succeeding to a default of the Prior Owner) in any material respect in the performance, observance or fulfillment of any of the material obligations, covenants or conditions contained in any Permitted Encumbrance, the Management Agreement or any other Material Agreement or instrument to which it is a party or by which it or the Property is bound except to the extent such default is not reasonably likely to have a Material Adverse Effect.

- 37 -

(f) Title. It has good and indefeasible title in fee to the real property constituting a part of the Property and owns no leasehold estates, as tenant, to any properties, and it has good and indefeasible title to the balance of the Property, in each case free and clear of all Liens whatsoever except the Permitted Encumbrances. The Mortgage, when properly recorded in the appropriate records, together with any Uniform Commercial Code financing statements required to be filed in connection therewith, will create (i) a valid, perfected first priority lien on the Property subject only to Permitted Encumbrances and the Liens created by the Loan Documents and (ii) perfected security interests in and to, and perfected collateral assignments of, all personalty (including the Leases), all in accordance with the terms thereof, subject only to any applicable Permitted Encumbrances. The Permitted Encumbrances do not and will not materially adversely affect or interfere with the value, or current use or operation, of the Property, or the security intended to be provided by the Mortgage or the ability of Borrower to repay the Notes or perform its obligations under any other Loan Document in accordance with the terms of the Loan Documents. Except as indicated in and insured over by a Qualified Title Insurance Policy, it has no Actual Knowledge of any claims for payment for work, labor or materials affecting the Property which are or may become a lien prior to, or of equal priority with, the Liens created by the Loan Documents (other than mechanics’ or materialmen’s liens for work or materials performed or supplied the costs for which are not yet past due or which are being contested in accordance with Section 5.1(b)(ii)). Nothing in this paragraph may be relied on by any title insurance company issuing a policy covering the Property. The Assignment of Leases, when properly recorded in the appropriate records, creates a valid first priority assignment of, or a valid first priority security interest in, Borrower’s rights under the Leases and the Rents, subject only to a license granted to Borrower to exercise certain rights and to perform certain obligations of the lessor under such Leases, including the right to operate the Property and, subject to Section 9.1.2 hereof, to collect and receive Rents. No Person other than Borrower owns any interest in any payments due under such Leases that is superior to or of equal priority with the Lender’s interest therein.

Giving effect to the transactions contemplated by the Loan Documents, the fair saleable value of its assets exceeds and will, immediately following the execution and delivery of the Loan Documents, exceed its total liabilities, including subordinated, unliquidated, disputed or contingent liabilities. The fair saleable value of its assets is and will, immediately following the execution and delivery of the Loan Documents, be greater than their probable liabilities, including the maximum amount of their contingent liabilities or their debts as such debts become absolute and matured. Borrower’s assets do not and, immediately following the execution and delivery of the Loan Documents will not, constitute unreasonably small capital to carry out its business as conducted or as proposed to be conducted. Borrower does not intend to, and does not believe that it will, incur debts and liabilities (including contingent liabilities and other commitments) beyond its ability to pay such debts as they mature (taking into account the timing and amounts to be payable on or in respect of its obligations).

(ff) Material and Management Agreements. To its Actual Knowledge each of the Material Agreements and the Management Agreement is in full force and effect and is valid and enforceable in all material respects, subject in each case to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; there are no defaults, breaches or violations thereunder by Borrower or, to Borrower’s Actual Knowledge, any other party thereto, and, to Borrower’s Actual Knowledge, there are no conditions (other than payments that are due but not yet delinquent and other non-delinquent executory obligations) that, with the passage of time or the giving of notice, or both, would constitute a default by any party thereunder, where with respect to any such Agreement the effect of one or more of any such defaults described in this paragraph would have a Material Adverse Effect. Neither the execution and delivery of the Loan Documents, Borrower’s performance thereunder, the recordation of the Mortgage, nor the exercise of any remedies by Lender, will have a Material Adverse Effect.

- 45 -

(gg) Employees. It either has no employees or has no material liability which has been incurred by it and remains unsatisfied for any taxes or penalties with respect to (i) any Employee Benefit Plan established, sponsored, maintained or contributed to by it on behalf of its employees at the Property or (ii) any “multiemployer plan” (as defined in Section 4001(a)(3) of ERISA) as to which it is making or has an obligation to make contributions or (iii) any lien which has been imposed on its assets pursuant to Section 412 of the Code or Sections 302 or 4068 of ERISA.

(hh) Rent Roll. The rent roll for the Property delivered to Lender on or prior to the Closing Date is true, correct and complete in all material respects.

(ii) Legal Compliance. To its Actual Knowledge, neither the Property nor any portion thereof is on the date hereof in violation of any Legal Requirement or any Insurance Requirement in a manner that is reasonably likely to have a Material Adverse Effect.

(jj) Security Deposits. It is in compliance with all applicable material Legal Requirements with respect to the Security Deposits.

Section 4.2 Survival of Representations. Borrower agrees that all of the representations and warranties set forth in Section 4.1 and elsewhere in this Agreement and in the other Loan Documents shall survive for so long as any portion of the Debt is outstanding (it being acknowledged by Lender that such representations and warranties have been made as of the Closing Date). Borrower acknowledges and agrees that all representations, warranties, covenants and agreements made in this Agreement or in the other Loan Documents by Borrower are a material inducement to the making of the Loan hereunder by Lender.

It will deliver to Lender, upon request, receipts for payment or other evidence satisfactory to Lender that the Taxes and Other Charges have been so paid (provided, however, that Borrower is not required to furnish such receipts for payment of Taxes in the event that such Taxes have been paid by Lender pursuant to Section 9.3.2 hereof). Subject to the provisions of 5.1(b)(ii) and other than Permitted Encumbrances, it shall not suffer and shall promptly cause to be paid and discharged any lien or charge whatsoever which may be or become a lien or charge against the Property and shall promptly pay for all utility services provided to the Property. Subject to Section 5.1(b)(ii), within thirty (30) days of obtaining knowledge thereof, it shall pay, bond or otherwise discharge, from time to time when the same shall become due, all claims and demands of mechanics, materialmen, laborers and others that, if unpaid, might result in, or permit the creation of, a lien or encumbrance on the Property or on the Rents arising therefrom.

(ii) Notwithstanding the foregoing, after prior written notice to Lender, Borrower, at its own expense, may contest by appropriate legal, administrative or other 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 Taxes or Other Charges or any Lien therefor or any Legal Requirement or Insurance Requirement or the application of any instrument of record affecting the Property or any part thereof (other than the Loan Documents) or any claims or judgments of mechanics, materialmen, suppliers, vendors or other Persons or any Lien therefor, and may withhold payment of the same pending such proceedings if permitted by law; provided that (A) no Default or Event of Default has occurred and remains uncured other than a Default or Event of Default resulting solely from the matter in question, (B) such proceeding shall suspend any collection of the contested Taxes, Other Charges or Liens from the Property, Borrower and Lender, (C) such proceeding shall be permitted under and be conducted in accordance with the provisions of any other instrument to which Borrower is subject and shall not constitute a default thereunder, (D) neither the Property nor any part thereof or interest therein will be in danger of being sold, forfeited, terminated, canceled or lost, (E) to the extent not already escrowed with Lender under Section 9.3 hereof, Borrower shall have furnished Lender with security (in an amount or type reasonably approved by Lender) to insure the payment of any such Taxes or Other Charges, or the cost of the contested Legal Requirement or Insurance Requirement or the removal of the Lien, in each case together with all reasonably anticipated interest and penalties thereon, (F) in the case of an Insurance Requirement, the failure of Borrower to comply therewith shall not impair the validity of any insurance required to be maintained by Borrower hereunder or the right to full payment of any claims thereunder, (G) in the case of any essential or significant service with respect to the Property, any contest or failure to pay will not result in a discontinuance of any such service, (H) in the case of any instrument of record affecting the Property or any part thereof, the contest or failure to perform under any such instrument shall not result in the placing of any Lien on the Property or any part thereof

- 47 -

(except if such Lien would be removed upon completion of such proceedings and the compliance by the parties with the terms of the resulting order, decision or determination and the removal costs for such Lien have been escrowed with Lender or in the proceeding), (I) except to the extent Borrower has provided sufficient Eligible Collateral therefor, neither the failure to pay or perform any obligation which Borrower is permitted to contest under this Section nor an adverse determination of any such contest shall result in a Material Adverse Effect, and (J) Borrower shall promptly upon final determination thereof pay the amount of any such Taxes, Other Charges or Liens, if any, together with all costs, interest and penalties which may be payable in connection therewith. Lender may pay over any such cash deposit or part thereof held by Lender to the claimant entitled thereto at any time when, in the good faith judgment of Lender, the entitlement of such claimant is finally established, and Lender shall otherwise remit any remaining such amounts to Borrower. Subject to the foregoing, at Borrower’s timely request, Lender shall not pay from the Tax and Insurance Escrow Account the contested Taxes or Other Charges being contested.

(c) Litigation. It shall give prompt written notice to Lender of any litigation or governmental proceedings commenced or to its Actual Knowledge threatened in writing against it which, if determined adversely to it, might reasonably be likely to have a Material Adverse Effect.

(i) Further Assurances. It shall, at its sole cost and expense:

(i) execute and deliver to Lender such documents, instruments, certificates, assignments and other writings, and do such other acts necessary or desirable, to evidence, preserve and/or protect the Lien of the Lender at any time securing or intended to secure the obligations of Borrower under the Loan Documents, as Lender may reasonably require; and

All such statements shall set forth the financial condition and the income and expenses for the Property for the immediately preceding Fiscal Year. Borrower’s audited annual financial statements shall be accompanied by a management report, in form and substance reasonably satisfactory to Lender, discussing the reconciliation between the financial statements for such Fiscal Year and the most recent Annual Budget.

Notwithstanding anything to the contrary contained herein, if following written notice from Borrower to Lender of Lender’s (or Servicer’s) failure to provide any financial information pursuant to Section 2.5.3 and the exercise by Borrower of reasonable diligence to obtain the same, Borrower is unable to include certain financial information required to be included in such Required Record or to make certain calculations required therefor, due to the failure of Lender or Servicer or either of their agents, representatives or employees to deliver such financial information, Borrower shall prepare and deliver to Lender the Required Records without such information, and calculations to the extent feasible (and, to the extent feasible, with good-faith estimates with respect to such missing information, clearly stated as estimates); provided, further that Borrower shall deliver revised financial reports or statements promptly following receipt of the necessary financial information from Lender, Servicer or other sources.

From and after the Anticipated Prepayment Date or if an Event of Default has occurred and is continuing, (i) Borrower shall prepare and deliver such Annual Budget to Lender for its approval, on or before November 1 of each year

during the Term and, promptly after preparation thereof, any subsequent revisions to such Annual Budget necessitated by unforeseeable events; provided that no more than one (1) such subsequent revision shall be permitted in any two (2) month period, (ii) such Annual Budget and any such subsequent revisions thereto shall be subject to Lender’s approval (which shall not be unreasonably withheld, conditioned or delayed), (iii) Borrower shall operate the Property in accordance with each such Annual Budget, subject to a five percent (5%) variance on Operating Expenses on a line-item basis (except that up to three (3) line items totaling no more than $250,000 may be aggregated for such variance), but in no event shall such additional amount exceed more than five percent (5%) of such month’s budgeted amount for all Operating Expenses, and (iv) if the period as to which any Annual Budget relates has expired and an Annual Budget for the next period has not been approved, then Borrower shall operate the Property in accordance with the last approved Annual Budget until a new Annual Budget has been approved; provided, however, that Borrower agrees to promptly submit revised Annual Budgets to Lender for its approval and shall work diligently and in good faith to respond to Lender’s objections to any Annual Budget. Notwithstanding the foregoing, Borrower shall have the right, without obtaining Lender’s prior approval (but subject to notifying Lender of the same and the amount thereof as soon as possible) to incur expenses in excess of the approved Annual Budget in the event of an emergency which, in the reasonable judgement of Borrower, requires immediate action to avoid imminent personal injury, material physical property damage or material devaluation or criminal liability.

(q) No Joint Assessment. Borrower shall not suffer, permit or initiate the joint assessment of the Property (i) with any other real property constituting a tax lot separate from the Property, and (ii) unless required by applicable law, with any portion of the Property which may be deemed to constitute personal property, or any other procedure whereby the lien of any taxes which may be levied against such personal property shall be assessed or levied or charged to the Property.

Borrower shall, within two Business Days of receipt thereof, deposit, directly into the escrow account referred to below, all security deposits, letters of credit or other collateral (“Security Deposits”) that it receives from time to time from any Tenant as security for the performance by such Tenant of its obligations under its Lease. Lender shall deposit any cash received from Borrower pursuant to the preceding sentence in an escrow account in the name of Lender (the “Security Deposit Account”) and, except to the extent required by law or the applicable Lease, the Security Deposit Account shall be maintained in accordance with the terms of Section 11.2. Borrower shall require each applicable Tenant to maintain in effect all existing and future letters of credit, bonds or other similar collateral which constitute Security Deposits (unless replaced by cash deposits) during the term of the applicable Lease (or so long as such tenant is required to maintain such Security Deposit under its Lease). Each future letter of credit, bond or other similar collateral that is a Security Deposit shall be issued by an institution reasonably satisfactory to Lender, shall, if permitted by applicable Legal Requirements, name Lender as payee, mortgagee or beneficiary (or, at Lender’s option, be fully assignable to Lender without any action being required to be taken by Borrower) and shall in all respects comply with all applicable Legal Requirements and otherwise be reasonably satisfactory to Lender. Borrower shall have the right to replace any Cash which was initially placed in the Security Deposit Account in lieu of a letter of credit, bond or similar collateral with a letter of credit, bond or similar collateral meeting the requirements of this Section 5.1(r). Lender shall

- 54 -

comply with all applicable Legal Requirements in holding such Security Deposits and, subject thereto, shall make such Security Deposits available to Borrower or the applicable Tenant on or prior to the tenth (10th) Business Day after notice from Borrower to the extent required to comply with obligations owed to such Tenant under the terms of its Lease or to Borrower, in the event Borrower is entitled to such deposit in accordance with the applicable Lease and applicable law by reason of such Tenant’s default under its Lease. Lender may commingle funds in the Security Deposit Account and Lender shall not be obligated to segregate, designate or separately account for any specific Security Deposit, except to the extent that such Security Deposit is required to be segregated by the applicable Lease or under applicable law.

(s) Management Agreements; Material Agreements. Borrower shall:

Notwithstanding anything to the contrary contained in the foregoing (except the parenthetical contained in Section 5.1(s)(iv)), and provided that no Event of Default has occurred and is continuing, Borrower shall at all times have the right to (A) replace the Current Manager or any other then current Manager, provided that (x) such Manager is at all times an Acceptable Manager, (y) Borrower shall comply with the provisions of Section 6.1(a) hereof and (z) such manager shall execute and deliver a consent agreement in form and substance substantially similar to the Consent of Manager referred to in Section 3.1(k) and (B) enter into new Material Agreements provided that such Agreements contain commercially reasonable terms and are negotiated on an arm’s-length basis and provided that Borrower is otherwise in compliance with the terms of this Agreement.

VI. NEGATIVE COVENANTS

(a) Operation of Properties. It shall not, without Lender’s prior consent (except as elsewhere herein expressly provided): (i) surrender, terminate or cancel any Material Agreement to which it is a party (unless, other than with respect to the REA, the other party thereto is in default or the termination of such agreement would be commercially reasonable), (ii) materially increase or consent to the material increase of the amount of any charges due from Borrower under any Material Agreement to which it is a party or any Management Agreement, except, other than with respect to the REA, as provided therein or on an arm’s-length basis and commercially reasonable terms; or (iii) otherwise modify, change, supplement, alter or amend, or waive or release any of its rights and remedies under any Material Agreement to which it is a party or any Management Agreement in any material respect, except, other than with respect to the REA, on an arm’s-length basis and commercially reasonable terms.

(b) Liens. Subject to Section 5.1(b)(ii), it shall not, without the prior written consent of Lender, which consent may be withheld in the sole discretion of Lender, create, incur, assume, permit or suffer to exist any Lien on any portion of the Property, except Permitted Encumbrances.

(d) Change in Business. It shall not enter into any line of business other than the ownership, maintenance, financing, refinancing and operation of the Property (in each case subject to the terms hereof), or make any material change in the scope or nature of its business objectives or purposes, or undertake or participate in activities other than the continuance of its present business.

(e) Debt Cancellation. It shall not cancel or otherwise forgive or release any claim or debt owed to Borrower by any Person, including any arising under any of the Leases, the Management Agreement and the Material Agreements except (i) with respect to the Leases, Management Agreements and Material Agreements, in accordance with and subject to the terms hereof and thereof and (ii) with respect to other matters, for adequate consideration in the ordinary course of Borrower’s business and on commercially reasonable terms, subject to other restrictions contained herein, if any, or in any other Loan Document.

(h) Borrower shall permit Lender, the Independent Architect, and Lender’s agents and representatives (including Servicer, Special Servicer, Lender’s engineer, architect or inspector) to enter onto the Property during normal business hours after reasonable notice considering the circumstances (subject to the rights of Tenants under the Leases) to inspect the progress of any work being performed by or on behalf of Borrower, including any Alterations or Expansions, and all materials being used in connection therewith, to examine all plans and shop drawings relating thereto and, following an Event of Default and during the continuance thereof, to undertake and complete any work required to be undertaken in accordance with the terms hereof Borrower shall cause all contractors and subcontractors to cooperate with Lender or Lender’s representatives or such other persons described above in connection with inspections described in this Section 7.1(h) or the undertaking or completion of work pursuant to this Section 7.1(h).

(i) Borrower shall collaterally assign to Lender, as additional security for the Loan, all rights and claims Borrower may have against all Persons supplying labor or materials in connection with any Alterations or Expansions; provided, however, Lender may not pursue any such right or claim unless an Event of Default has occurred and remains uncured.

Section 7.2 Leasing.

(a) Borrower shall have the right, without the prior written consent of Lender to, enter into a new individual Lease or a Lease renewal affecting less than 75,000 rentable square feet of the Property, and thereafter to modify or amend the same, in each case without the consent of Lender but subject to the provisions of clauses (b) and (c) below. Borrower shall have the right, without the prior written consent of Lender, to terminate an individual Lease affecting less than 75,000 rentable square feet of the Property; provided that, in the aggregate over any six (6) month period, individual Leases affecting 125,000 rentable square feet or more may not be terminated without Lender’s prior written consent and provided that such termination is on commercially reasonable terms and shall not materially adversely affect the value of the Property. Borrower shall not, without the prior written consent of Lender, enter into a new individual Lease or a Lease renewal (other than a renewal it is obligated to enter into pursuant to the existing Lease) or terminate any individual Lease after the date hereof affecting 75,000 or more rentable square feet of the Property.

(b) All new Leases entered into from and after the date hereof shall be on the Lease Form approved by Lender pursuant to Section 3.1(v), without any changes to such Lease Form which would be materially adverse to Lender, shall be the result of arm’s-length negotiations, shall in the aggregate (taking into account all terms of such Lease, such as rent concessions, landlord’s obligations on Tenant Improvements and other economic benefits or concessions) provide for “market” rental rates and other market terms and shall not contain any additional terms which would materially adversely affect Lender’s rights under the Loan Documents (provided that the rent payable under a new Lease may be below market rate if (x) the lessee is a managing and/or leasing agent for Borrower and the space leased under the new Lease is to be used solely in connection with the managing and leasing of the Property and is of a size reasonably required for an office for such agent for such purposes, or (y) the rents from the space leased under the new Lease were, immediately prior to the entry into that Lease, below market rate, such new Lease was given in exchange for the surrender of the prior Lease

- 69 -

and the below market discount reflected in such new Lease is not more than the below market discount of the Lease being surrendered); all future Leases shall provide that they are subordinate to the Mortgage and that the lessee agrees to attorn to Lender at Lender’s request and may, in the case of the Leases described in clause (e) below, make subordination conditioned upon the granting of non-disturbance rights acceptable to Lender.

(c) Borrower (i) shall observe and perform the obligations imposed upon the lessor under the Leases in a commercially reasonable manner; (ii) shall enforce the material terms, covenants and conditions contained in the Leases upon the part of the lessee thereunder to be observed or performed in a commercially reasonable manner; (iii) shall not collect any of the rents more than one (1) month in advance (other than Security Deposits); (iv) shall not execute any assignment of lessor’s interest in the Leases or the Rents (except for the Assignment of Leases); (v) shall not alter, modify or change the terms of the Leases in a manner which shall materially adversely effect Lender’s rights or remedies under the Loan Documents; and (vi) subject to the provisions of Section 5.1(n), shall execute and deliver at the request of Lender all such further assurances, confirmations and assignments in connection with the Leases as Lender shall from time to time reasonably require.

(d) With respect to Leases affecting 75,000 or more rentable square feet of the Property, Borrower may, at its discretion, submit for Lender’s approval (which shall not be unreasonably withheld, conditioned or delayed) leasing guidelines (the “Leasing Guidelines”) (provided that in all events Leasing Guidelines shall expire not later than one year after their initial approval). Subject to clause (b) above, any such Lease, which conforms in all material respects with approved Leasing Guidelines and the approved Lease Form will not be subject to Lender’s prior written consent. Any Lease submitted to Lender for Lender’s approval, which shall be accompanied by (x) an Officer’s Certificate on behalf of Borrower stating that said Lease complies in all respects with the requirements of clause (b) above and (y) a summary of the material terms of such Lease (including the economic terms and any termination options), shall be deemed approved if Lender shall have not notified Borrower in writing of its disapproval (together with a statement of the grounds of such disapproval) within three Business Days after Borrower has given Lender written notice that at least three (3) Business Days have elapsed since such submission).

(e) Lender shall enter into, execute and deliver a nondisturbance and attornment agreement, in form and substance acceptable to Lender in its reasonable discretion, among Lender and any Tenant under a Lease which is permitted under or which has been approved (or deemed to have been approved) in accordance with the terms of this Agreement and which (i) with respect to a Lease of retail space, affects 1,000 square feet or more of rentable space in the Property or (ii) with respect to all other Leases, affects 14,000 or more rentable square feet of the Property, provided that, in each such case, such Tenant also executes and delivers such agreement in favor of Lender.

(f) Borrower shall be entitled to retain (i) any termination payment paid by former tenants Clark, Ladner, ▇▇▇▇▇▇▇▇▇▇▇ and ▇▇▇▇▇ or LeShoppe, Inc. or (ii) any other payment, fee or penalty (“Termination Fee”) paid by a Tenant in connection with the exercise of an express cancellation or termination clause provided in such Lease, if and only if at the time of such cancellation or termination, the Net Operating Income for the Property (exclusive of the

- 70 -

then applicable Above Market IBM Rent Component) for the most recent trailing 12-month period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) (excluding any Net Operating Income received during such period in respect of the Lease being canceled or terminated) is $7,500,000 or more. In all other circumstances not covered by the first sentence of this clause (f), and provided that no Default or Event of Default has occurred and is continuing, any Termination Fee shall be deposited in the Deposit Account within two (2) Business Days of receipt thereof and shall be applied, on the next Payment Date, in the following order of priority: (i) to the funding of the Tax and Insurance Escrow Account to the extent required to cause such account to be in the amount required under Section 9.3; (ii) to the payment of the Monthly Debt Service Payment Amount; (iii) to the funding of the Leasing Reserve Account to the extent required to cause such account to be in the amount required under Section 9.4; (iv) to the funding of the Capital Reserve Account to the extent required to cause such account to be in the amount required under Section 9.4; and (v) to the funding of the Low Debt Service Reserve Account to the extent required under Section 9.4. After payment of the foregoing items, all remaining funds shall be deposited in a separate Eligible Account in which Lender is hereby granted a security interest (the “Termination Payment Account”), which funds are only to be released from such account (a) to reimburse Borrower for the capital costs and expenses required to lease that portion of the Improvements affected by such cancellation or termination, such reimbursement to be made in the manner provided by, and in accordance with, the provisions of Section 9.2.2 relating to Leasing Commissions and Tenant Improvement costs (and for so long as there are funds in the Termination Payment Account, funds in the Leasing Reserve Account shall not be available for the reimbursement of such capital costs and expenses) or (b) to Borrower if Borrower delivers to Lender evidence satisfactory to Lender that the premises which were affected by such cancellation or termination have been fully relet to a tenant and that Borrower has no obligation whatsoever to pay for or perform any tenant improvement work in connection with such reletting; provided that the foregoing provisions shall not apply if a Default or an Event of Default has occurred and is continuing.

(g) Borrower acknowledges that, because an Affiliate of Borrower owns the property which is immediately adjacent to the Property (the “Adjacent Property”), Borrower may have the opportunity to direct potential tenants to the Property or to the Adjacent Property. Recognizing such conflict of interest, and recognizing that it is in the best interest of Lender for the Property to be occupied fully, Borrower agrees that it will at all times conduct its leasing activities in a manner which is commercially fair and reasonable to the Property.

(h) On or before April 15, 1998, Borrower shall deliver to Lender Subordination, Nondisturbance and Attornment Agreements in substantially the same form as the Subordination and Attornment Agreements granted by The Mitsubishi Trust and Banking Corporation, or such other form as may be reasonably Acceptable to Lender, executed by each Tenant set forth on Schedule 3.

(vi) During any period of repair or restoration, builder’s “all risk” insurance in an amount equal to not less than the full insurable value of the Property against such risks (including fire and extended coverage and collapse of the Improvements to agreed limits) as are customarily obtained for such work by prudent owners in the locality where the Property is located;

(vii) Coverage to compensate for the cost of demolition and the increased cost of construction for the Property in an amount reasonably satisfactory to Lender, and

(viii) Such other insurance as may from time to time be reasonably required by Lender in order to protect its interests.

(c) All policies of insurance (the “Policies”) required pursuant to this Section 8.1.1(i) shall be issued by companies approved by Lender and licensed to do business in the Commonwealth of Pennsylvania, and unless otherwise approved by Lender and the applicable Rating Agencies in writing, shall have a claims paying ability rating of “AA” or better by the applicable Rating Agencies, provided that, for so long as United States Fidelity and Guaranty Corp. (“USF&G”), American Protection Insurance Company or The Travellers Indemnity Company has a claims paying ability rating of not less than its rating as of the Closing Date, USF&G, American Protection Insurance Company and The Travellers Indemnity Company shall each be deemed an approved company pursuant to this clause (i); (ii) shall name Lender and its successors and/or assigns as their interest may appear as an additional insured and as a loss payee (except that in the case of general liability insurance, Lender shall be named an additional insured and not a loss payee); (iii) shall contain a non-contributory standard lender clause and, except with respect to general liability insurance and worker’s compensation insurance, a Lender’s Loss Payable Endorsement, or their equivalents, and a separate endorsement naming Lender as the person to which all payments made by such insurance company shall be paid; (iv) shall include effective waivers by the insurer of all claims for insurance premiums against all loss payees, additional insureds and named insured (other than Borrower) and all rights of subrogation against any loss payee, additional insured or named insured; (v) subject to the provisions of Section 8.1.1(a), shall be subject to a deductible, if any,

- 73 -

not greater in any material respect, in proportion to the coverage maintained, than the deductible for such coverage on the date hereof; (vi) shall contain such provisions as Lender deems reasonably necessary or desirable to protect its interest including endorsements providing that neither Borrower, Lender nor any other party shall be a co-insurer under said Policies and that no modification, reduction, cancellation or termination in amount of, or material change (other than an increase) in, coverage of any of the Policies shall be effective until at least thirty (30) days after receipt by each named insured, additional insured and loss payee of written notice thereof, (vii) shall permit Lender to pay the premiums and continue any insurance upon failure of Borrower to pay premiums when due, upon the insolvency of Borrower or through foreclosure or other transfer of title to the Property (it being understood that Borrower’s rights to coverage under such policies may not be assignable without the consent of the insurer); and (viii) shall provide that the insurance shall not be impaired or invalidated by virtue of (A) any act, failure to act, negligence of, or violation of declarations, warranties or conditions contained in such policy by, Borrower, Lender or any other named insured, additional insured or loss payee, except for the willful misconduct of Lender knowingly in violation of the conditions of such policy, (B) the occupation, use, operation or maintenance of the Property for purposes more hazardous than permitted by the terms of the Policy, (C) any foreclosure or other proceeding or notice of sale relating to the Improvements or the Equipment or (D) any change in the possession of the Improvements or Equipment without a change in the identity of the holder of actual title to such Improvements or Equipment (provided that with respect to items (C) and (D), any notice requirements of the applicable Policies are satisfied).

(d) Insurance Premiums; Certificates of Insurance.

(i) Borrower shall pay (or cause to be paid) the premiums for such Policies (the “Insurance Premiums”) as the same become due and payable and shall furnish to Lender the receipts for the payment of the Insurance Premiums or other evidence of such payment reasonably satisfactory to Lender (provided, however, that Borrower is not required to furnish such evidence of payment to Lender if such Insurance Premiums are to be paid by Lender pursuant to the terms of this Agreement). Within thirty (30) days after request by Lender, but not more frequently than once annually, Borrower shall obtain such increases in the amounts of coverage required hereunder as may be reasonably requested by Lender, taking into consideration changes in liability and/or laws, changes in prudent customs and practices. In the event Borrower satisfies the requirements under this Section 8.1.1 through the use of a Policy covering other properties, then (unless such policy is provided in substantially the same manner as it is as of the date hereof), Borrower shall provide evidence reasonably satisfactory to Lender that the Insurance Premiums for the Property is separately allocated under such Policy to the Property and that payment of such allocated amount shall maintain the effectiveness of such Policy as to the Property notwithstanding the failure of payment of any other portion of premiums. If no such allocation is available, Lender shall have the right to increase the Tax and Insurance Escrow in an amount sufficient to purchase a non-blanket Policy covering only the Property from insurance companies which qualify under this Agreement.

(ii) Borrower shall deliver to Lender on or prior to the Closing Date certificates setting forth in reasonable detail the material terms (including any applicable

- 74 -

notice requirements) of all Policies from the respective insurance companies (or their authorized agents) that issued the Policies, including that such Policies may not be canceled, modified, reduced or terminated without thirty (30) days’ prior notice to Lender and stating that all premiums then due thereon have been paid to the applicable insurers for the current period and that the same are in full force and effect. Borrower shall deliver to Lender, concurrently with each material change in any Policy, a certificate with respect to such changed Policy certified by the insurance company issuing that Policy, in substantially the same form and containing substantially the same information as the certificates required to be delivered by Borrower pursuant to the first sentence of this clause (d)(ii) and stating that all premiums then due thereon have been paid to the applicable insurers and that the same are in full force and effect (or if such certificate and report shall not be obtainable by Borrower, Borrower may deliver an Officer’s Certificate to such effect in lieu thereof).

(e) Renewal and Replacement of Policies.

(i) Not less than fifteen (15) days prior to the expiration, termination or cancellation of any Policy, Borrower shall renew such policy or obtain a replacement policy or policies (or a binding commitment for such replacement policy or policies), which shall be effective no later than the date of the expiration, termination or cancellation of the previous policy, and shall deliver to Lender a certificate in respect of such policy or policies (A) containing the same information as the certificates required to be delivered by Borrower pursuant to clause (d)(ii) above, or a copy of the binding commitment for such policy or policies and (B) confirming that such policy complies with all requirements hereof.

(ii) If Borrower does not furnish to Lender the certificates as required under clause (e)(i), Lender may procure, but shall not be obligated to procure, such replacement policy or policies and pay the Insurance Premiums therefor, and Borrower agrees to reimburse Lender for the cost of such Insurance Premiums promptly on demand.

(iii) Concurrently with the delivery of each replacement policy or a binding commitment for the same pursuant to this clause (e), Borrower shall deliver to Lender a report from a reputable and experienced insurance broker or from the insurer, setting forth the particulars as to all insurance obtained by Borrower pursuant to this Section 8.1.1 and then in effect and stating that all Insurance Premiums then due thereon have been paid in full to the applicable insurers, that such insurance policies are in full force and effect and that, in the opinion of such insurance broker or insurer, such insurance otherwise complies in all material respects with the requirements of this Section 8.1.1 (or if such report shall not be available after Borrower shall have used its reasonable efforts to provide the same, Borrower will deliver to Lender an Officer’s Certificate containing the information to be provided in such report).

(f) Separate Insurance. Borrower will not take out separate insurance concurrent in form or contributing in the event of loss with that required to be maintained pursuant to this Section 8.1.1 unless such insurance complies with clause (c) above.

- 75 -

(g) Securitization. In the event of a Securitization, Borrower shall name any trustee, Servicer or Special Servicer designated by Lender as a loss payee, and any trustee, Servicer and Special Servicer as additional insureds, with respect to any Policy for which Lender is to be so named hereunder.

8.1.2 Casualty; Application of Proceeds.

(a) Right to Adjust.

(i) If the Property is damaged or destroyed, in whole or in part, by fire or other casualty (a “Casualty”), Borrower shall (except to the extent such damage or destruction is in a de minimis amount) give prompt written notice thereof to Lender, generally describing the nature and extent of such Casualty. Following the occurrence of a Casualty, Borrower, regardless of whether proceeds are available, shall in a reasonably prompt manner proceed to restore, repair, replace, or rebuild the Property to the extent practicable to be of at least equal value and of substantially the same character as prior to the Casualty, all in accordance with the terms hereof applicable to Alterations.

(ii) Subject to clause (iv) below, in the event of any Casualty, Borrower may settle and adjust any claim with respect thereto; provided that such adjustment is carried out in a competent and timely manner. In such case, Borrower is hereby authorized to collect and receipt for Lender any Proceeds.

(iii) All Proceeds shall be due and payable solely to Lender and held and applied in accordance with the terms hereof or, if paid to Borrower, shall be held in trust by Borrower for the benefit of Lender and shall be paid over to Lender by Borrower within one Business Day of receipt.

(iv) Lender shall have the sole authority to adjust any claim with respect to a Casualty and to collect all Proceeds if an Event of Default shall have occurred and is continuing.

(b) Borrower’s Right to Apply to Restoration or Repayment. In the event of a Casualty or Condemnation where the loss is in an aggregate amount less than thirty percent (30%) of the original principal amount of the Loan, where access to the Improvements is not materially adversely affected by such Casualty or Condemnation and where Lender has received evidence satisfactory to it that no individual Lease affecting 150,000 rentable square feet or more, and no Leases in the aggregate affecting 150,000 rentable square feet or more, will be terminated or canceled as a result of such Casualty or Condemnation (a “Minor Loss”), Lender shall permit the application of the Proceeds to pay, or to reimburse Borrower, at the option of Borrower, for the cost of restoring, repairing, replacing or rebuilding the Property (the “Restoration”), in the manner required hereby, provided and on the condition that, no Event of Default shall have occurred and be then continuing and, in the reasonable judgment of Lender exercised in good faith:

(i) the Property can be restored to an economic unit not less valuable and not less useful than the same was prior to the Casualty or Condemnation,

- 76 -

(ii) the Restoration can be completed by the earliest to occur of:

(A) the 365th day after the Casualty or Condemnation or, with Rating Confirmation, such longer period as may reasonably be required,

(B) the 180th day prior to the Stated Maturity Date with respect to the Tranche A Note, and

(C) with respect to a Casualty only, the expiration of the payment period on the rental-loss insurance coverage in respect of such Casualty, and

(iii) during the period of the Restoration, the sum of (A) income derived from the Property, plus (B) proceeds of rent loss insurance or business interruption insurance, if any, payable, plus (C) any Cash deposited with, or any Credit Facility made available to, Lender (which Credit Facility shall be in form and substance, and the issuer thereof shall be, reasonably satisfactory to Lender), will equal or exceed one hundred five percent (105%) of the sum of (1) Operating Expenses and (2) the Debt Service.

If any of the conditions so forth in the proviso in this clause (b) is not satisfied, then, notwithstanding anything herein to the contrary, unless Lender shall otherwise elect, at its sole option, the Proceeds shall be applied to the prepayment of the Loan in accordance with the terms of Section 8.1.2(d).

(c) Lender’s Right to Apply to Repayment. In the event of a Casualty or Condemnation which is not a Minor Loss (a “Material Casualty” or “Material Condemnation”, as applicable), then Lender shall have the option (to be exercised by notice to Borrower given not later than the thirtieth (30th) day after the receipt of the Proceeds) to apply the net Proceeds to the prepayment of the Debt in accordance with Section 8.1.2(d) or to reimburse Borrower for the cost of any Restoration in the manner set forth below in Section 8.1.2(e) (and Lender shall be deemed to have elected prepayment if it shall fail to have given such notice within said 30-day period).

(d) Application of Prepayment. Any application of Proceeds to the Debt pursuant to Section 8.1.2(b) or (c) shall be without any prepayment premium or penalty except that if an Event of Default has occurred and is continuing, then Borrower shall pay to Lender an additional amount equal to the Yield Maintenance Payments, if any, that would be required in respect of the principal being prepaid assuming Section 2.3.3 hereof were applicable. Any such application to the Debt shall be applied to those payments of principal and interest last due under the Notes and shall not postpone or reduce any payments otherwise required pursuant to the Notes other than such last due payments.

(e) Manner of Restoration and Reimbursement. If Borrower is entitled pursuant to Section 8.1.2(b) or (c) to reimbursement out of Proceeds (and the conditions specified therein shall have been satisfied), such Proceeds shall be disbursed from time to time upon Lender being furnished with (i) such architect’s certificates, waivers of lien for the cost of work previously paid for with a prior disbursement, contractor’s sworn statements, title insurance endorsements, bonds, plats of survey and such other evidences of cost, payment and performance as are

- 77 -

customary and reasonably obtainable by prudent property owners in the locality in which the Property is located and as Lender may reasonably require and approve, and (ii) all plans and specifications for such Restoration, such plans and specifications to be approved by Lender prior to commencement of any work (such approval not to be unreasonably withheld, conditioned or delayed). In addition, no payment made prior to the Final Completion of the Restoration shall exceed ninety-five percent (95%) of the value of the work performed from time to time; funds deposited by Borrower with Lender for any deficiency shall be disbursed prior to disbursement of such Proceeds; and at all times, the undisbursed balance of such Proceeds remaining in the hands of Lender, together with funds deposited for that purpose or irrevocably committed to the satisfaction of Lender by or on behalf of Borrower for that purpose, shall be at least sufficient in the reasonable judgment of Lender exercised in good faith to pay for the cost of completion of the Restoration, free and clear of all Liens or claims for Lien. Prior to any disbursement, Lender shall have received evidence reasonably satisfactory to it of the estimated cost of completion of the Restoration, and Borrower shall have deposited with Lender Eligible Collateral in an amount equal to the excess (if any) of such estimated cost of completion over the net Proceeds. Any surplus which may remain out of Proceeds received pursuant to a Casualty shall be paid to Borrower after payment of such costs of Restoration. Any surplus which may remain out of Proceeds received pursuant to a Condemnation shall be escrowed with Lender as security for the Debt after payment of such costs of Restoration.

8.1.3 Condemnation. (a) Borrower shall promptly give Lender written notice of the actual or, to Borrower’s Actual Knowledge, proposed, contemplated or threatened in writing commencement of any taking, condemnation, or eminent domain proceeding or similar proceeding affecting the Property (a “Condemnation”) and shall deliver to Lender copies of any and all papers served in connection with such Condemnation. Following the occurrence of a Condemnation, Borrower, regardless of whether Proceeds are available, shall promptly proceed to restore, repair, replace or rebuild the same to the extent practicable to be of at least equal value and of substantially the same character as prior to such Condemnation, all to be effected in accordance with the terms hereof applicable to Alterations.

(b) Lender is hereby irrevocably appointed as Borrower’s attorney-in-fact, coupled with an interest, with exclusive power to collect, receive and retain any Proceeds in respect of a Condemnation and to make any compromise or settlement in connection with such Condemnation, subject to the provisions of this Section. Provided no Default or Event of Default has occurred and is continuing, Borrower may settle and compromise such Proceeds, provided that the same is effected in a competent and timely manner. Notwithstanding any Condemnation by any public or quasi-public authority (including any transfer made in lieu of or in anticipation of such a Condemnation), Borrower shall continue to pay the Debt at the time and in the manner provided for in the Notes, this Agreement and the other Loan Documents, and the Debt shall not be reduced unless and until any Proceeds shall have been actually received and applied by Lender to expenses of collecting such Proceeds and to discharge of the Debt. Lender shall not be limited to the interest paid on the Proceeds by the condemning authority but shall be entitled to receive out of the Proceeds interest at the rate or rates provided in the Notes. Borrower shall cause any Proceeds that are payable to Borrower to be paid directly to Lender to be held and applied in accordance with the terms hereof.

require the Cash Hold until such reserve accounts are funded in the initial amounts required as of the Closing Date):

(a) an account in the amount of $4,497,025 for the payment of Tenant Improvement expenses and Leasing Commissions (the “Leasing Reserve Account”); subsequent to the Closing, monies shall be transferred in accordance with Section 9.4 hereof from the Deposit Account into the Leasing Reserve Account;

(b) an account, initially at zero, for the payment of routine capital improvements (excluding Tenant Improvements and Leasing Commissions and, until the Deferred Maintenance Reserve Account has been reduced to zero, Deferred Maintenance Conditions) at the Property (the “Capital Reserve Account”); subsequent to the Closing, monies shall be transferred in accordance with Section 9.4 hereof from the Deposit Account into the Capital Reserve Account;

(c) a reserve account in the initial amount of $352,000, for the payment of the cost of remediating the Deferred Maintenance Conditions (the “Deferred Maintenance Reserve Account”); and

Each of the Leasing Reserve Account, Capital Reserve Account, Deferred Maintenance Reserve Account and Unpaid TI/Leasing Commissions Reserve Account (each, a “Reserve Account”) shall be in the name of and under the sole dominion and control of Lender, subject only to Lender’s obligations hereunder to advance funds therefrom in accordance with this Agreement, and Borrower shall have no authority or power to make withdrawals from said Reserve Accounts. The amount required in each Reserve Account as of the Closing Date shall be deposited on Borrower’s behalf by Lender’s funding said amount out of the proceeds of the Loan provided that, in lieu of all (but not part of) such initial deposits and other deposits to the Leasing Reserve Account or the Deferred Maintenance Reserve Account required to be made hereunder, Borrower may, until the ninth (9th) anniversary of the Closing Date only, deliver to Lender, a Credit Facility or Facilities in the amounts required to be deposited in each such Reserve Account, in form and substance acceptable to Lender (in its reasonable discretion) and approved by a Rating Confirmation; and provided further, however, that with respect to any Credit Facility delivered in lieu of deposits to the Leasing Reserve Account, (i) such Credit Facility shall have an annual expiration date of July 1st and shall be renewed by Borrower in accordance with the definition of Credit Facility and (ii) at the time of each such renewal the amount of such Credit Facility shall equal the amount set forth for such date on Schedule 7 (the “Leasing Reserve Account Balance”); provided further, however, that the required amount of such Credit Facility (and accordingly, the Leasing Reserve Account Balance) shall be reduced in an amount equal to the aggregate amount of all Tenant Improvement costs and Leasing Commissions disbursed to Borrower pursuant to the provisions of Section 9.2.2 or expended by Borrower out of other funds (provided that Lender has been provided with evidence reasonably satisfactory to it that such funds have been expended for Tenant Improvement costs or Leasing Commissions) with respect

to new Leases (or Lease extensions) relating to the initial reletting of the IBM Space which have an initial term which expires after September 20, 2006 (such amount being hereinafter referred to as the “IBM Space Reduction Amount”). Borrower may from time to time convert all or any part of a Credit Facility into Cash, or replace all or any part of the Cash in a Reserve Account with a Credit Facility in the amount of the then applicable Leasing Reserve Account Balance and otherwise meeting the requirements for such Credit Facility set forth above. From and after such ninth (9th) anniversary date all and any Credit Facilities delivered in lieu of such deposits in such Reserve Accounts shall be replaced with immediately available funds and, to the extent that immediately available funds have not been deposited in such Reserve Accounts by such ninth (9th) anniversary date, Lender shall have the right at any time on or after such date to draw upon any Credit Facilities delivered in lieu of deposits and hold the proceeds of such Credit Facilities and apply the same in accordance with the terms hereof. Funds in each Reserve Account shall not be commingled with any other monies.

Notwithstanding anything to the contrary contained in this Article IX, Borrower shall have the right at any time after September 20, 2002 to request the Rating Agencies to modify the Leasing Reserve Account Balances, and if the Rating Agencies shall agree in their sole discretion to any such modification and shall issue a Rating Confirmation with respect thereto, then such modification shall be made without requiring the consent of Lender.

9.2.2 Disbursements from the Reserve Accounts. (a) Borrower shall have the right to obtain disbursements from time to time or to require that a Credit Facility be drawn upon from time to time: (1) with respect to the Leasing Reserve Account, for Leasing Commissions and Tenant Improvement costs incurred by Borrower in connection with a new Lease (or Lease extension) entered into in accordance with the terms hereof; provided, however, that with respect to any Leasing Commission or Tenant Improvement cost relating to the initial reletting of the IBM Space, such new Lease (or Lease extension) must have an initial term which expires on or after September 20, 2006, (2) with respect to the Capital Reserve Account, for routine capital improvements made by Borrower at the Property in accordance with the terms hereof (excluding Tenant Improvements and Leasing Commissions and Deferred Maintenance Conditions), (3) with respect to the Deferred Maintenance Reserve Account, for expenses incurred by Borrower in remediating any Deferred Maintenance Condition in accordance with the terms hereof and, following the completion of such remediation, the balance thereof may be used for capital improvements at the Property (provided, that such use following such completion shall not be permitted unless (x) Borrower shall have delivered to Lender an Officer’s Certificate stating that all such remediation has been completed ‘in accordance with the terms hereof as specified in Schedule 1 and (y) Lender shall have delivered a written confirmation, not to be unreasonably withheld, that it concurs in such statement contained in such Officer’s Certificate), and (4) with respect to the Unpaid TI/Leasing Commissions Reserve Account, for the Tenant Costs incurred by Borrower in connection with any of the Leases identified on Schedule 6 hereto up to the allocated amounts for each such Lease, as set forth on such Schedule, in each case on the following terms and conditions:

(i) disbursements or draws on a Credit Facility shall be made only to pay or to reimburse Borrower in respect of actual costs of the work or payments in respect of Tenant Costs made, which costs or payments were approved by Lender (such approval not to be unreasonably withheld, conditioned or delayed) or made in accordance with Section 7.1;

- 81 -

(ii) each request for a disbursement from any Reserve Account or a draw on a Credit Facility shall be in a form specified or approved by Lender, shall specify the work or payment for Tenant Costs, as the case may be, for which the disbursement or drawdown is requested and shall include an Officer’s Certificate certifying that such funds will be applied (x) to pay or reimburse for materials or work permitted hereunder and done in accordance herewith, and shall be accompanied by copies of invoices for all items or materials purchased and all contracted labor or services provided or (y) to pay for Tenant Costs permitted hereunder;

(iii) Lender shall have received from Borrower evidence reasonably satisfactory to Lender that Borrower has incurred such expenses and, to the extent applicable, that the materials for which the request is made are on site at the Property and are properly secured or have been installed in the Property; with respect to disbursements from the Deferred Maintenance Reserve Account and the Unpaid TI/Leasing Commission Reserve Account (or draws on Credit Facilities related thereto), the funds remaining in the Reserve Account in question or remaining undrawn on the applicable Credit Facility in question shall be, in Lender’s reasonable judgment made in good faith, sufficient to pay the balance of the items contemplated to be funded therefrom when required to be so paid, and Lender shall receive any Lien waivers or other releases as are customarily and reasonably obtained by prudent property owners in the locality in which the Property is located and as Lender may reasonably require; and

(iv) Lender shall disburse from the Reserve Account in question or draw on the Credit Facility in question, or authorize such disbursement or drawing, within five (5) Business Days after the receipt of Borrower’s request for such disbursement or draw and the satisfaction of the other conditions set forth above in this Section, but in no event more often than once in any 10-day period, the amount requested by Borrower for such expenses, provided, however:

(A) with respect to the Deferred Maintenance Reserve Account, in no event shall the amount so disbursed or drawn exceed the amount set forth on Schedule 1 for the remediation of the item in question; and

(B) with respect to the Unpaid TI/Leasing Commission Reserve Account, in no event shall the amount so disbursed or drawn with respect to a Lease exceed the amount set forth for such Lease on Schedule 6 for the Tenant Costs in question.

9.2.3 No Other Disbursements from Reserve Accounts. Except as provided in Sections 9.2.2 and 9.2.4, Borrower shall not be entitled to any disbursements from the Reserve Accounts or any drawing on the applicable Credit Facilities, even if the work for which a particular Reserve Account was established has been completed and funds remain in such Reserve Account.

9.2.4 Release of Accounts Upon Repayment or Defeasance. Lender shall disburse to Borrower, or draw on the Credit Facilities, on the date that the Debt shall be paid or Defeased in full by Borrower, all amounts remaining in the Reserve Accounts, the Deposit Account and any other accounts established pursuant to this Agreement, or all amounts remaining undrawn on the Credit Facilities.

- 82 -

9.2.5 Obligations Unaffected. The insufficiency of any balance in any Reserve Account shall not relieve Borrower from its obligation to fulfill all preservation and maintenance covenants in the Loan Documents.

Section 9.3 Tax and Insurance Escrow Account.

9.3.1 Establishment. On or prior to the Closing Date Borrower shall establish a separate account or accounts (the “Tax and Insurance Escrow Account”), and Borrower shall deposit therein on each Payment Date:

(a) one-twelfth (1/12) of the Taxes and Other Charges that Lender reasonably estimates will be payable during the next ensuing twelve (12) months in order to accumulate with Lender sufficient funds to pay all such Taxes and Other Charges at least thirty (30) days prior to their respective delinquent dates, and

(b) one-twelfth (1/12) of the Insurance Premiums that Lender estimates will be payable for the renewal of the coverage afforded by the Policies upon the expiration thereof in order to accumulate with Lender sufficient funds to pay all such Insurance Premiums at least thirty (30) days prior to the expiration of the Policies.

On the Closing Date, Lender on behalf of Borrower shall disburse from the Loan to the Tax and Insurance Escrow Account an amount equal to (i) the product of the next installment of Taxes and Other Charges times a fraction, the numerator of which is the number of months in the installment period for such Taxes and Other Charges elapsed as of the Closing Date (rounded up to the nearest integer) and the denominator of which is the number of months in such installment period, and (ii) the product of the next installment of Insurance Premiums payable times a fraction, the numerator of which is the number of months in the installment period for such Premiums elapsed as of the Closing Date (rounded up to the nearest integer) and the denominator of which is the number of months in such installment period. Amounts in the Tax and Insurance Escrow Account may only be invested in Permitted Investments in accordance with Section 11.2.

9.3.2 Application Generally. Lender will apply amounts in the Tax and Insurance Escrow Account either: (x) to pay Taxes and Other Charges and Insurance Premiums required to be made by Borrower hereunder (and so long as the Tax and Insurance Escrow Account shall have a balance at least equal to the then-payable Taxes, Other Charges and Insurance Premiums, Borrower shall not be in default hereunder if Lender shall have not so applied such balance to the payment of such Taxes, Other Charges and Insurance Premiums, unless Lender shall have not so applied such balance at the request of Borrower) or (y) to reimburse Borrower for such amounts upon presentation of evidence of payment and an Officer’s Certificate in form and substance reasonably satisfactory to Lender, subject, however in the case of (x) or (y), to Borrower’s right to contest Taxes and Other Charges in accordance with the terms hereof. In making any payment from or to the Tax and Insurance Escrow Account, Lender may do so according to any ▇▇▇▇, statement or estimate procured from the appropriate public office (with respect to Taxes and Other Charges) or insurer or agent (with respect to Insurance Premiums), without inquiry into the accuracy of such ▇▇▇▇, statement or estimate or into the validity of any tax, assessment, sale, forfeiture, tax lien or title or claim thereof unless Lender was given written notice by Borrower of such inaccuracy, invalidity or other contest, in each

- 83 -

case in accordance with Section 5.1(b)(ii). If the amount in the Tax and Insurance Escrow Account shall exceed the amounts due for Taxes and Other Charges and Insurance Premiums, Lender shall, at its option, return any excess to Borrower or credit such excess against future payments to be made to the Tax and Insurance Escrow Account. Provided no Event of Default has occurred and is continuing, Borrower shall have the right to have Lender apply amounts deposited in the Tax and Insurance Escrow Account on account of Taxes and Other Charges toward the payment of such Taxes and Other Charges prior to their delinquent dates for the purpose of achieving a discount on such Taxes and Other Charges obligation. If at any time Lender reasonably determines that the amount in the Tax and Insurance Escrow Account is not or will not be sufficient to pay the items set forth in Sections 9.3.1(a) and 9.3.1(b) above, Lender shall notify Borrower of such determination and Borrower shall increase its monthly payments to Lender by the amount that Lender estimates is sufficient to make up the deficiency at least thirty (30) days prior to delinquency of the Taxes and Other Changes and/or expiration of the Policies, as the case may be.

Section 9.4 Disbursements from the Deposit Account; Borrower’s Obligation to Fund Deposit Account.

- 84 -

(d) on each Payment Date occurring in July through and including December, to the Leasing Reserve Account, except to the extent a Credit Facility delivered therefor pursuant to Section 9.2.1 remains undrawn, an amount equal to one-sixth (1/6th) of the amount required to cause the amount in the Leasing Reserve Account to equal the Leasing Reserve Account Balance set forth for such year on Schedule 7; provided, however, that the Leasing Reserve Account Balance shall be reduced in an amount equal to the IBM Space Reduction Amount;

(e) to the Capital Reserve Account, an amount equal to the amount shown on Schedule 8 hereto (regardless of the amount then in such Capital Reserve Account);

(f) to Borrower, an amount equal to the Capital Expenditures set forth in the Annual Budget (approved by Lender to the extent such approval is required pursuant to Section 5.1(p)) for the month immediately prior to the month in which such Payment Date occurs; provided that Borrower shall have delivered to Lender an Officer’s Certificate, dated no less than five (5) days prior to such Payment Date, that there is not outstanding for more than sixty (60) days any amounts (other than de minimis amounts) claimed by any creditor to be due and owing from Borrower for prior capital improvements (except for claims any Borrower is in good faith contesting and the payment for which Borrower has escrowed with Lender), and that the amounts disbursed to Borrower pursuant to this clause (f) shall be used by Borrower within the next sixty (60) days solely to pay for Capital Expenditures;

(g) to Borrower to pay the costs of extraordinary Capital Expenditures approved in writing by Lender to the extent such approval is required pursuant to Section 5.1(p);

(h) if the Mezzanine Loan is then outstanding, to the Mezzanine Lender in an amount equal to all amounts then due and payable to the Mezzanine Lender (provided that Lender shall have been notified of such amount at least six (6) Business Days prior to each Payment Date);

(i) to the Preferred Equity Holder an amount equal to all amounts then due and payable to the Preferred Equity Holder (provided that Lender shall have been notified of such amount at least six (6) Business Days prior to each Payment Date); and

Notwithstanding the foregoing, if at any time during the Term, the Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) for the most current trailing 12-month period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) is less than $8,000,000, all amounts remaining in the Deposit Account after the transfers described in clauses (a) through (f) above shall be deposited in a separate Eligible Account in which Lender is hereby granted a security interest (the “Low Debt Service Reserve Account”); provided, however, that if at the time in question, either (1) at such time the aggregate Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) for the most current trailing 6-month period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) plus the Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) as projected in

- 85 -

good faith by Borrower (taking into account only Leases which are then in place) and reasonably agreed to by Lender for the 6-month period immediately following such trailing 6-month period shall equal or exceed $8,000,000, or (2) if the time in question occurs during the year 2003, the Net Operating Income for the Property (exclusive of then applicable Above Market IBM Rent Component) as projected in good faith by Borrower (taking into account only Leases which are then in place) and reasonably agreed to by Lender for the 12-month period immediately following the last period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) shall equal or exceed $8,000,000, then notwithstanding the foregoing, in either case, the amounts remaining in the Deposit Account shall not be deposited into the Low Debt Service Reserve Account and shall instead be distributed as provided in clauses (g) through (j) above. If at any time (i) the Net Operating Income for the Property for any such 12-month (exclusive of the then applicable Above Market IBM Rent Component) period is less than $7,000,000, or (ii) if an Event of Default has occurred and is continuing, all amounts on deposit in the Low Debt Service Reserve Account shall be applied, on each Payment Date occurring during the period that the conditions in clause (i) or (ii) apply, to prepay principal due under the Notes until the principal amount of the Notes is paid in full; provided, however, that provided that no Event of Default has occurred and is continuing, if either (1) at such time the aggregate Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) for the most recent trailing 6-month period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) plus the Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) projected in good faith by Borrower (taking into account only Leases which are then in place) and reasonably agreed to by Lender for the 6-month period immediately following such trailing 6-month period shall equal or exceed $7,000,000, or (2) if the time in question occurs during the year 2003, the Net Operating Income for the Property (exclusive of then applicable Above Market IBM Rent Component) as projected in good faith by Borrower (taking into account only Leases which are then in place) and reasonably agreed to by Lender for the 12-month period immediately following the last period for which Borrower has furnished the statements required by Section 5.1(j)(iii)(B) shall equal or exceed $7,000,000, then notwithstanding the foregoing, in either case, the amounts on deposit in the Low Debt Service Reserve Account shall not be applied to prepay the Notes; provided, further however, that if after establishment of the Low Debt Service Reserve Account, any such trailing 12-month Net Operating Income for the Property (exclusive of the then applicable Above Market IBM Rent Component) exceeds $8,000,000 for four (4) consecutive quarters and provided no Event of Default has occurred and is continuing, all amounts on deposit in the Low Debt Service Reserve Account shall be released to Borrower. The foregoing provisions shall not apply during any Hyperamortization Period (during which period the provisions of Section 9.4.2 shall apply). Lender acknowledges that, as of the Closing Date, no Low Debt Service Reserve Account is required hereunder.

- 86 -

9.4.2 Disbursements After the Anticipated Prepayment Date. On each Payment Date from and after the Anticipated Prepayment Date until the entire Debt has been paid in full (such period, the “Hyperamortization Period”), provided no Event of Default has occurred and is continuing, and subject to Section 9.4.3, Lender shall transfer from the Deposit Account (or authorize such transfer), to the extent available therein, the following payments in the following order of priority:

(a) to the Tax and Insurance Escrow Account, the amounts required to be reserved pursuant to Section 9.3 hereof,

(b) to Lender to pay the Monthly Debt Service Payment Amount for the Loan, which amount shall immediately be available and payable to Lender;

(c) to Borrower, payments for monthly Operating Expenses approved by Lender pursuant to the Annual Budget in accordance with the provisions of Section 9.4.1(c);

(d) to the Leasing Reserve Account, except to the extent a Credit Facility delivered therefor pursuant to Section 9.2.1 remains undrawn, in accordance with the provisions of Section 9.4.1(d);

(e) to the Capital Reserve Account, in accordance with the provisions of Section 9.4.1(e);

(f) to Borrower, payments for monthly Capital Expenditures approved by Lender pursuant to the Annual Budget, in accordance with the provisions of Section 9.4.1(f);

(g) to Borrower to pay the costs of extraordinary Capital Expenditures approved in writing by Lender;

(h) to Lender, to prepay the principal amount outstanding under the Tranche A Note until the principal amount of the Tranche A Note is paid in full;

(i) to Lender, to be applied against Accrued Interest with respect to the Tranche A Note; and

(k) to the Preferred Equity Holder in an amount equal to all amounts then due and payable to the Preferred Equity Holder (provided that Lender shall have been notified of such amount at least six (6) Business Days prior to each Payment Date); and

(l) to Borrower or its designee, as Borrower shall direct, any funds remaining in the Deposit Account.

However, the failure of Borrower to pay any amounts required to be paid under clauses (g) through (k) above, including Accrued Interest on a Payment Date, as a result of insufficient funds in the Deposit Account for such payment shall not constitute an Event of Default hereunder. All Accrued Interest shall nonetheless be due and payable on the Maturity Date.

9.4.3 Obligation to Fund; Deemed Payment. In the event that on any Payment Date the amount in the Deposit Account shall be insufficient to make all of the transfers described in Sections 9.4.1(a) through (f) or 9.4.2(a) through (f) above, as applicable; Borrower

- 87 -

shall deposit into the Deposit Account on such Payment Date the amount of such deficiency, and if Borrower shall fail to make such deposit in accordance with the provisions of Section 10.1(a), the same shall be an Event of Default and, in addition to all other rights and remedies provided for hereunder, Lender may disburse and apply the amounts in the Deposit Account in such order as Lender may determine. Notwithstanding the foregoing, Borrower shall not be obligated to deposit a deficiency in accordance with the immediately preceding sentence to the extent that Borrower shall have paid directly any amount included within the budgeted amounts for which disbursement would otherwise be made for the month in question in accordance with Sections 9.4.1(a), (c) or (f) or 9.4.2(a), (c) or (f), as applicable, as established to Lender’s reasonable satisfaction prior to the date that Borrower shall otherwise be obligated to deposit such deficiency in accordance with the immediately preceding sentence of this Section 9.4.3. If on any Payment Date the amount in the Deposit Account shall be sufficient to make all of the transfers described in Sections 9.4.1(a) through (f) or 9.4.2(a) through (f) above, as applicable, Borrower shall be deemed to have paid the Monthly Debt Service Payment Amount and the deposits in the Reserve Accounts required by Sections 9.4.1(a), (c), (d), (e) and (f) or 9.4.2(a), (c), (d), (e) and (f), as applicable, unless Lender is legally constrained from transferring such amount in accordance with Sections 9.4.1(a) through (f) or 9.4.2(a) through (f) above, as applicable, by reason of (x) any bankruptcy or insolvency related to Borrower or (y) any other event of which Lender has delivered written notice to Borrower at least three Business Days prior to the applicable Payment Date; provided, however, that Borrower shall not be relieved from its obligations to make any such payments in the absence of such notice and that Borrower shall be in Default if it fails to make any such payments by such Payment Date.

9.4.4 Borrower to Provide for Reconciliation of Excess Disbursements. In the event that the quarterly reports delivered by Borrower pursuant to Section 5.1(j)(iv)(B) shall show that the actual Operating Expenses and Capital Expenditures incurred by Borrower with respect to the period covered by such report shall be different than the amounts actually received by Borrower as disbursements from the Deposit Account pursuant to Sections 9.4.1(c), (e), (f) and (g) or 9.4.2 (c), (e), (f) and (g), as applicable, including the second proviso of Section 9.4.1(c), with respect to the corresponding period (or such difference shall otherwise be established), and the Capital Reserve Account or the Leasing Reserve Account has a balance less than the balance that such Reserve Account(s) would otherwise have had, or Lender received less than would have received under Sections 9.4.2(h) or (i), as applicable, if the amounts disbursed to Borrower pursuant to the aforementioned Sections equaled such actual Operating Expenses and Capital Expenditures, then Borrower shall deposit into such Reserve Account(s) the amount or, to the extent permitted hereunder, deliver a Credit Facility in the amount that should otherwise have been deposited into such Reserve Account(s) or paid to Lender as principal or Accrued Interest. Such deposit or payment shall be made not later than three (3) Business Days after the date on which Borrower’s quarterly report under Section 5.1(j)(iv)(B) is required to be delivered hereunder.

Section 9.5 No Release if Event of Default Exists. Notwithstanding the terms hereof, in no event shall Lender have any obligation to disburse funds from the Deposit Account, Termination Payment Account, Security Deposit Account, Low Debt Service Reserve Account, Tax and Insurance Escrow Account or any Reserve Account for so long as an Event of Default shall have occurred and be continuing.

- 88 -

Section 9.6 Grant of Security Interest; Rights upon Default. (a) Subject to the provisions of this Agreement permitting the release of funds in certain accounts under certain circumstances, Borrower hereby pledges, assigns and grants a security interest to Lender, as security for payment of all sums due in respect of the Loan and the performance of all other terms, conditions and covenants of this Agreement and any other Loan Document on Borrower’s part to be paid and performed, all of Borrower’s right, title and interest in and to the Deposit Account, the Termination Payment Account, the Security Deposit Account (subject to the rights of Tenants therein), the Low Debt Service Reserve Account, each Reserve Account and the Tax and Insurance Escrow Account, together with the deposits therein; including all interest earned thereon and Permitted Investments held therein. Borrower shall not, without obtaining the prior written consent of Lender, which consent may be withheld in the sole discretion of Lender, further pledge, assign or grant any security interest in any such account, or permit any Lien or encumbrance to attach thereto, or any levy to be made thereon, or any UCC-1 Financing Statements, except those naming Lender as the secured party, to be filed with respect thereto.

(b) Upon the occurrence, and during the continuance of an Event of Default, Lender may draw upon any Credit Facilities delivered in lieu of deposits into any Reserve Accounts and apply the proceeds thereof and any other amounts in the Deposit Account, the Termination Payment Account, the Low Debt Service Reserve Account, any Reserve Account and the Tax and Insurance Escrow Account (or any portion thereof) and to the extent permitted by applicable law and the applicable Leases, the Security Deposit Account, for any of the following purposes relating to the Loan or Borrower’s obligations hereunder or under any other Loan Document, and in any order, as Lender shall elect in its sole discretion: (i) Taxes and Other Charges; (ii) Insurance Premiums; (iii) interest on the unpaid principal balance of the Notes; (iv) amortization of the unpaid principal balance of the Notes; (v) Accrued Interest; (vi) Default Interest; (vii) completion of all work required to be performed hereunder, (viii) reimbursement of Lender for all losses (other than consequential damages) and expenses (including reasonable legal fees and disbursements) suffered or incurred by Lender as a result of such Event of Default; (ix) the cost of any repair or replacement to the Property; (x) payment of any amount expended in exercising rights and remedies available to Lender at law or in equity or under this Agreement or under any of the other Loan Documents; or (xi) any other portion of the Debt then due and payable (whether by acceleration or otherwise), including the Yield Maintenance Payments applicable to any full or partial prepayment; provided that Yield Maintenance Payments and Default Interest will not be applied to repayment of the Debt prior to payment in full of all principal and accrued interest (other than Default Interest).

Section 9.7 Lender Not Responsible. Nothing in this Article IX or elsewhere in the Loan Documents shall make Lender responsible for making or completing any work in respect of the Property, or obligate Lender to demand from Borrower additional sums to make or complete any work.

Section 9.8 Disbursements Relating to Material Alterations. For any work (or series of related items of work) that would constitute a Material Alteration, disbursement of funds therefor shall be subject to compliance by Borrower of the provisions of Section 7.1(g) hereof.

- 89 -

Section 9.9 Cash Hold During a Letter of Credit Default. Notwithstanding anything to the contrary contained in this Agreement or the Deposit Account Agreement, so long as a Letter of Credit Default shall exist, all amounts on deposit in the Deposit Account shall remain therein and Borrower shall have no right to require or request any disbursements therefrom, including without limitation, any disbursements pursuant to Sections 9.2.2 or 9.4 (the foregoing restrictions are hereinafter referred to as the “Cash Hold”).

(vii) if a receiver, liquidator or trustee shall be appointed for Borrower or if Borrower shall be adjudicated a bankrupt or insolvent, or if any petition for bankruptcy, reorganization or arrangement pursuant to federal bankruptcy law, or any similar federal or state law, shall be filed by or against, consented to, or acquiesced in by, Borrower, or if any proceeding for the dissolution or liquidation of Borrower shall be instituted; provided, however, if such appointment, adjudication, petition or proceeding

- 90 -

was involuntary and not consented to by Borrower, upon the same not being discharged, stayed or dismissed within ninety (90) days;

(viii) if Borrower attempts to assign its respective rights under this Agreement or under any other Loan Document or any interest herein or therein in contravention of this Agreement or any of the Loan Documents;

(ix) if any of the covenants contained in Section 6.1 (other than Section 6.1(i)) are breached or if Borrower breaches any covenant contained in Section 4.1(cc) hereof and, if the same is susceptible of cure, the same is not cured within thirty (30) days after written notice thereof from Lender; provided, that no cure of a breach of any covenant contained in Section 4.1(cc) shall be effective unless Borrower causes to be delivered to Lender an opinion as to non-consolidation in form and substance and from counsel reasonably satisfactory to Lender, which opinion takes into account such breach;

(x) if an Event of Default as defined or described in any of the other Loan Documents occurs and is continuing, or if any other such event shall occur or condition shall exist, if the effect of such event or condition is to accelerate the maturity of any portion of the Debt or to permit Lender to accelerate the maturity of all or any portion of the Debt in accordance with the terms of any such Loan Document;

(xi) if Borrower shall be in default of its obligations to make deposits into the Tax and Insurance Escrow Account, the Termination Payment Account, the Leasing Reserve Account, the Security Deposit Account, the Low Debt Service Account, the Capital Reserve Account, or the Deposit Account or in any other reserve or escrow account required hereunder and such default continues for three (3) Business Days after notice from Lender;

(xii) if any Subordination and Attornment Agreement referred to in Section 7.2(h) is not delivered in accordance therewith, provided, however, that, other than with respect to the Affiliate Office Leases, if Borrower is diligently and expeditiously pursuing the obtaining of such Subordination and Attornment Agreements (including, without limitation, through the exercise of all remedies available to Borrower against such Tenant for failure to deliver such Subordination and Attornment Agreement), then such failure shall not be an Event of Default; or

(xiii) except as provided in Section 5.1(j)(viii), if Borrower shall continue to be in default under any of the other terms, covenants or conditions of this Agreement not specified in subsections (i) to (xii) above, for ten (10) days after notice to Borrower from Lender, in the case of any Default which can be cured by the payment of a sum of money, or for thirty (30) days after notice from Lender in the case of any other Default; provided, however, that if such nonmonetary Default is susceptible of cure but cannot reasonably be cured within such 30-day period and provided further that Borrower shall have commenced to cure such default within such 30-day period and thereafter diligently and expeditiously proceeds to cure the same, such 30-day period shall be extended for an additional period of time as is reasonably necessary for Borrower in the

- 91 -

exercise of due diligence to cure such Default, such additional period not to exceed one hundred and twenty (120) days.

(b) Upon the occurrence of an Event of Default and at any time thereafter Lender may, in addition to any other rights or remedies available to it pursuant to this Agreement or any other Loan Document, or at law or in equity, take such action, without notice or demand, that Lender deems advisable to protect and enforce its rights against Borrower and in and to all or any portion of the Property, including declaring the Debt to be immediately due and payable (provided, however, with respect to an Event of Default described in clauses (vi), (vii) or (viii) above, the Debt and all other obligations of Borrower hereunder and under the other Loan Documents shall immediately and automatically become due and payable, without notice or demand, and Borrower hereby expressly waives any such notice or demand, anything contained herein or in any other Loan Document to the contrary notwithstanding), and Lender may enforce or avail itself of any or all rights or remedies provided in the Loan Documents against Borrower and any or all of the Properties, including all rights or remedies available at law or in equity.

Section 10.2 Remedies. (a) Upon the occurrence of an Event of Default, all or any one or more of the rights, powers, privileges and other remedies available to Lender against Borrower under this Agreement or any of the other Loan Documents executed and delivered by, or applicable to, Borrower or at law or in equity may be exercised by Lender at any time and from time to time, whether or not all or any of the Debt shall be declared due and payable, and whether or not Lender shall have commenced any foreclosure proceeding or other action for the enforcement of its rights and remedies under any of the Loan Documents with respect to all or any portion of the Property. Any such actions taken by Lender shall be cumulative and concurrent and may be pursued independently, singly, successively, together or otherwise, at such time and in such order as Lender may determine in its sole discretion, to the fullest extent permitted by law, without impairing or otherwise affecting the other rights and remedies of Lender permitted by law, equity or contract or as set forth herein or in the other Loan Documents. Without limiting the generality of the foregoing, to the extent permitted by applicable Legal Requirements, Borrower agrees that if an Event of Default is continuing (i) Lender is not subject to any “one action” or “election of remedies” law or rule, and (ii) all liens and other rights, remedies or privileges provided to Lender shall remain in full force and effect until Lender has exhausted all of its remedies against the Property and the Mortgage has been foreclosed, sold and/or otherwise realized upon in satisfaction of the Debt or the Debt has been paid in full.

(b) Upon the occurrence of an Event of Default, Lender shall have the right from time to time to sever each Note and the other Loan Documents into one or more separate notes, mortgages and other security documents in such denominations as Lender shall determine in its sole discretion for purposes of evidencing and enforcing its rights and remedies provided hereunder. Borrower shall execute and deliver to Lender from time to time, promptly after the request of Lender, a severance agreement and such other documents as Lender shall request in order to effect the severance described in the preceding sentence, all in form and substance reasonably satisfactory to Lender. Borrower hereby absolutely and irrevocably appoints Lender as its true and lawful attorney, coupled with an interest, in its name and stead to make and execute all documents necessary or desirable to effect the aforesaid severance, Borrower

- 92 -

ratifying all that its said attorney shall do by virtue thereof; provided Lender shall not avail itself of such power of attorney without first giving each Borrower five (5) days’ prior notice.

Section 10.3 Remedies Cumulative. The rights, powers and remedies of Lender under this Agreement shall be cumulative and not exclusive of any other right, power or remedy which Lender may have against Borrower pursuant to this Agreement or the other Loan Documents, or existing at law or in equity or otherwise. Lender’s rights, powers and remedies may be pursued singly, concurrently or otherwise, at such time and in such order as Lender may determine in Lender’s sole discretion. No delay or omission to exercise any remedy, right or power accruing upon an Event of Default shall impair any such remedy, right or power or shall be construed as a waiver thereof, but any such remedy, right or power may be exercised from time to time and as often as may be deemed expedient. A waiver of one Default or Event of Default with respect to Borrower shall not be construed to be a waiver of any subsequent Default or Event of Default with respect to Borrower or to impair any remedy, right or power consequent thereon.

XI. MISCELLANEOUS

Section 11.1 Survival. (a) This Agreement and all covenants, agreements, representations and warranties made herein and in the certificates delivered pursuant hereto shall survive the making by Lender of the Loan and the execution and delivery to Lender of the Notes, and shall continue in full force and effect so long as all or any of the Debt of Borrower is outstanding and unpaid.

(b) Whenever in this Agreement any Person is referred to, such reference shall be deemed to include the legal representatives, successors and assigns of such Person (provided that the foregoing shall not be deemed to permit any transfer of any ownership interest that is otherwise prohibited hereunder). All covenants, promises and agreements in this Agreement contained, by or on behalf of Borrower, shall inure to the benefit of the respective legal representatives, successors and assigns of Lender.

Section 11.2 Permitted Investments; Eligible Accounts; Eligible Institutions. Lender shall invest any amounts to be held by Lender in accordance with the terms of this Agreement or any other Loan Document, pending the application of such amounts to the purposes herein or therein provided, in one of the Permitted Investments as directed by Borrower from time to time (provided no Event of Default has occurred and is continuing) or Lender from time to time (if any Event of Default has occurred and is continuing). If Borrower is entitled to choose the Permitted Investments but fails to do so, such amounts may remain in the Eligible Accounts until receipt by Lender of such direction by Borrower. Lender shall not be responsible for its inability to invest funds received after 1:30 p.m. New York City time, but shall invest such sums on the following Business Day. Except as otherwise provided in Section 7.1(h)(vi), after application to the purposes for which any amounts invested pursuant to this Section 11.2 are held and so long as no Event of Default has occurred and is continuing hereunder, any investment income earned from such investments shall be paid to Borrower. All accounts maintained hereunder, including the Deposit Account, the Termination Payment Account, the Low Debt Service Reserve Account, the Reserve Accounts and the Tax and Insurance Escrow

- 93 -

Account, shall, at Lender’s election, be (1) an account or account maintained with a federal or state-chartered depository institution or trust company which complies with the definition of Eligible Institution (as defined below) or (2) a segregated trust account or accounts maintained with the corporate trust department of a federal depository institution or state-chartered depository institution subject to regulations regarding fiduciary funds on deposit similar to Title 12 of the Code of Federal Regulations Section 9.10(b) which, in either case, has corporate trust powers, acting in its fiduciary capacity (such accounts, “Eligible Accounts”). “Eligible Institutions” are institutions whose (1) commercial paper, short-term debt obligations or other short-term deposits are rated at least “A-1+” (or the equivalent) by each applicable Rating Agency, if the deposits are to be held in the account for less than 35 days, or (2) long-term senior unsecured debt obligations are rated at least “AA”, if the deposits are to be held in the account for more than 30 days. Following a rating downgrade, withdrawal, qualification or suspension of such institution’s rating, each account must promptly (and in any case within not more than 30 calendar days) be moved to a qualifying institution or to one or more segregated trust accounts in the trust department of such institution, if permitted. No Eligible Account shall be evidenced by a certificate of deposit, passbook or other instrument. Each Eligible Account (A) shall be a separate and identifiable account from all other funds held by the holding institution, (B) shall be established and maintained in the name of the Lender (and subsequent to any Securitization, shall bear a designation clearly indicating that the funds deposited therein are held for the benefit of the holders of the Certificates), (C) shall be under the sole dominion and control of Lender, and shall contain only funds held for its benefit. All costs and expenses incurred in establishing and maintaining any account or reserve held by Lender pursuant to this Agreement or any other Loan Document shall be borne by Borrower (except in the case of the Deposit Account with respect to which Lender shall be responsible for the costs only of establishing (as opposed to maintaining) such account) and such costs and expenses may be paid out of any income earned by way of investment of amounts in such accounts or reserves or, if insufficient, from amounts in such accounts. Anything to the contrary herein notwithstanding, the parties hereto agree that, for so long as Chase or First Union has (i) a long term senior unsecured credit rating and (ii) a short term credit rating, in each case by the applicable Rating Agencies not less than its rating as of the Closing Date, each of Chase and First Union shall be deemed an Eligible Institution for purposes of maintaining all accounts hereunder provided any such accounts so maintained shall be Eligible Accounts.

Neither any failure nor any delay on the part of Lender in insisting upon strict performance of any term, condition, covenant or agreement, or exercising any right, power, remedy or privilege hereunder, or under any Note or under any other Loan Document, or any other instrument given as security therefor, shall operate as or constitute a waiver thereof, nor shall a single or partial exercise thereof preclude any other future exercise, or the exercise of any other right, power, remedy or privilege. In particular, and not by way of limitation, by accepting payment after the due date of any amount payable under this Agreement, any Note or any other Loan Document, Lender shall not be deemed to have waived any right either to require prompt payment when due of all other amounts due under this Agreement, the Notes or the other Loan Documents, or to declare a default for failure to effect prompt payment of any such other amount.

Section 11.8 Headings. The Article and/or Section headings and the Table of Contents in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 11.9 Severability. Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

Section 11.10 Preferences. Subject to Article IX, Lender shall have the continuing and exclusive right to apply or reverse and reapply any and all payments by Borrower to any portion of the obligations of Borrower hereunder. To the extent Borrower makes a payment or payments to Lender, which payment or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or proceeds received, the obligations hereunder or part thereof intended to be satisfied shall be revived and continue in full force and effect, as if such payment or proceeds had not been received by Lender.

Section 11.11 Waiver of Notice. Borrower shall not be entitled to any notices of any nature whatsoever from Lender except with respect to matters for which this Agreement or the other Loan Documents specifically and expressly provide for the giving of notice by Lender to Borrower and except with respect to matters for which Borrower is not, pursuant to applicable Legal Requirements, permitted to waive the giving of notice. Borrower hereby expressly waives

- 98 -

the right to receive any notice from Lender with respect to any matter for which this Agreement or the other Loan Documents do not specifically and expressly provide for the giving of notice by Lender to Borrower.

Section 11.12 Remedies of Borrower; Consents. In the event that a claim or adjudication is made that Lender or its agents, including Servicer or Special Servicer, have acted unreasonably or unreasonably delayed (or refrained from), acting in any case where by law or under this Agreement or the other Loan Documents, Lender or such agent, as the case may be, has an obligation to act reasonably or promptly, Borrower agrees that neither Lender nor its agents, including Servicer and Special Servicer, shall be liable for any monetary damages, and Borrower’s sole remedies shall be limited to commencing an action seeking injunctive relief or declaratory judgment, except in any instance in which it has been finally determined that Lender’s action, delay or inaction has constituted gross negligence, fraud, willful misconduct or an illegal act. The parties hereto agree that any action or proceeding to determine whether Lender has acted reasonably shall be determined by an action seeking declaratory judgment.

Section 11.13 Expenses; Indemnity. (a) Borrower covenants and agrees to reimburse Lender upon receipt of written notice from Lender for (i) all reasonable costs and expenses incurred by or on behalf of Lender in connection with Borrower’s ongoing performance of and compliance with Borrower’s respective agreements and covenants contained in this Agreement and the other Loan Documents on its part to be performed or complied with after the Closing Date, including confirmation by the Lender of compliance with environmental and insurance requirements; (ii) all reasonable costs and expenses incurred by or on behalf of Lender in connection with the negotiation, preparation, execution, delivery and administration of any consents, amendments, waivers or other modifications to this Agreement and the other Loan Documents requested by Borrower, and any other documents or matters reasonably requested by Lender after the Closing Date; (iii) filing and recording fees and expenses, title insurance, reasonable fees and expenses of counsel for providing to Lender all legal opinions required after the Closing Date, and other similar expenses incurred in maintaining the Liens in favor of Lender pursuant to this Agreement and the other Loan Documents; (iv) all costs and expenses incurred by or on behalf of Lender in connection with enforcing or preserving any rights, in response to third party claims or the prosecuting or defending of any action or proceeding or other litigation, in each case against, under or affecting Borrower, this Agreement, the other Loan Documents, the Property or any other security given for the Loan, and (v) all costs and expenses incurred by or on behalf of Lender in connection with enforcing any obligations of or collecting any payments due from Borrower under this Agreement, the other Loan Documents or with respect to the Property or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in the nature of a “work-out” or of any insolvency or bankruptcy proceedings; provided, however, Borrower shall not be liable for the payment of any such costs and expenses to the extent the same arise by reason of the gross negligence, illegal acts, fraud or willful misconduct of Lender. Any costs and expenses due and payable to Lender hereunder which are not paid by Borrower within ten (10) Business Days after demand may be paid from any amounts in the Deposit Account, with notice thereof to Borrower.

(b) Borrower shall indemnify and hold harmless Lender from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including the reasonable

- 99 -

fees and disbursements of counsel for Lender in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not Lender shall be designated a party thereto), that may be imposed on, incurred by, or asserted against Lender in any manner relating to or arising out of any breach by Borrower of its obligations under, or any material misrepresentation by Borrower contained in this Agreement or the other Loan Documents; provided, however, Borrower shall not be liable for the payment of any such costs and expenses to the extent the same arise by reason of the gross negligence, illegal acts, fraud or willful misconduct of Lender. Any costs and expenses due and payable to Lender hereunder which are not paid by Borrower within ten (10) Business Days after demand may be paid from any amounts in the Deposit Account with notice thereof to Borrower.

(c) The provisions of Section 11.13(a)(iv) and 11.13(b) shall survive the expiration and termination of this Agreement and the repayment of the Debt.

Section 11.15 Offsets, Counterclaims and Defenses. Any assignee of Lender’s interest in and to this Agreement, the Notes and the other Loan Documents shall take the same free and clear of all offsets, counterclaims or defenses which are unrelated to such documents which Borrower may otherwise have against any assignor of such documents, and no such unrelated counterclaim or defense shall be interposed or asserted by Borrower in any action or proceeding brought by any such assignee upon such documents and any such right to interpose or assert any such unrelated offset, counterclaim or defense in any such action or proceeding is hereby expressly waived by Borrower.

Section 11.16 No Joint Venture or Partnership. Borrower and Lender intend that the relationships created hereunder and under the other Loan Documents be solely that of borrower and lender. Nothing herein or therein is intended to create a joint venture, partnership, tenancy-in-common, or joint tenancy relationship between Borrower and Lender nor to grant Lender any interest in the Property other than that of mortgagee or lender.

Section 11.17 Publicity. Except in connection with publicity relating to or facilitating a Securitization or as otherwise set forth in the Cooperation Agreement (with respect to any of which Lender may refer to ▇▇▇▇▇▇ Development Partners and may refer to Lazard Frères and their respective Affiliates), all news releases, publicity or advertising by Lender, Borrower or their respective Affiliates through any media intended to reach the general public which refers to the Loan Documents or the financing evidenced by the Loan Documents, or to Lender, Borrower, Goldman, the Loan purchaser, the Servicer or the trustee in a Securitization, shall be subject to the prior written approval of all such parties.

Section 11.18 Waiver of Marshaling of Assets. To the fullest extent Borrower may legally do so, Borrower waives all rights to a marshaling of the assets of Borrower, Borrower’s partners, if any, and others with interests in Borrower, and of the Property, or to a sale in inverse order of alienation in the event of foreclosure of the interests hereby created, and agrees not to assert any right under any laws pertaining to the marshaling of assets, the sale in

- 100 -

inverse order of alienation, homestead exemption, the administration of estates of decedents, or any other matters whatsoever to defeat, reduce or affect the right of Lender under the Loan Documents to a sale of the Property for the collection of the Debt without any prior or different resort for collection, of the right of Lender to the payment of the related Debt out of the net proceeds of the Property in preference to every other claimant whatsoever.

Section 11.19 Waiver of Counterclaim. Borrower hereby waives the right to assert a counterclaim, other than a compulsory counterclaim, in any action or proceeding brought against it by Lender or its agents, including Servicer and Special Servicer.

Section 11.20 Conflict; Construction of Documents. In the event of any conflict between the provisions of this Agreement and any of the other Loan Documents, the provisions of this Agreement shall control. The parties hereto acknowledge that they were represented by counsel in connection with the negotiation and drafting of the Loan Documents and that such Loan Documents shall not be subject to the principle of construing their meaning against the party which drafted same.

Section 11.21 Brokers and Financial Advisors. (a) Borrower hereby represents that it has dealt with no financial advisors, brokers, underwriters, placement agents, agents or finders in connection with the transactions contemplated by this Agreement. Borrower hereby indemnifies Lender and its affiliates and holds Lender and its affiliates each harmless from and against any and all claims, liabilities, costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) of any kind in any way relating to or arising from a claim by any Person that such Person acted on behalf of Borrower or its affiliates or any of its agents or representatives in connection with the transactions contemplated herein. The provisions of this Section 11.21(a) shall survive the expiration and termination of this Agreement and the repayment of the Debt.

(b) Lender hereby represents that it has dealt with no brokers or finders in connection with the transactions contemplated by this Agreement, other than Goldman. Lender hereby indemnifies Borrower and its respective affiliates and holds Borrower and its respective affiliates, each harmless from and against any and all claims, liabilities, costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) of any kind in any way relating to or arising from a claim by any Person (including, without limitation, Goldman) that such Person acted on behalf of Lender or its affiliates or any of its agents or representatives in connection with the transactions contemplated herein. The provisions of this Section 11.21(b) shall survive the expiration and termination of this Agreement and the repayment of the Debt.

Section 11.22 No Third Party Beneficiaries. This Agreement and the other Loan Documents are solely for the benefit of Lender and Borrower, and nothing contained in this Agreement or the other Loan Documents shall be deemed to confer upon anyone other than Lender and Borrower any right to insist upon or to enforce the performance or observance of any of the obligations contained herein or therein. All conditions to the obligations of Lender to make the Loan hereunder are imposed solely and exclusively for the benefit of Lender, and no other Person shall have standing to require satisfaction of such conditions in accordance with their terms or be entitled to assume that Lender will refuse to make the Loan in the absence of strict compliance with any or all thereof and no other Person shall under any circumstances be

Section 11.24 Exculpation. Subject to the qualifications below, Lender shall not enforce the liability and obligation of Borrower to perform and observe the obligations contained in the Notes, this Agreement, the Mortgage or the other Loan Documents by any action or proceeding wherein a money judgment shall be sought against Borrower, unless, except as expressly reserved to Lender in clause (g) below, the judgment in any such action or proceeding shall be enforceable against Borrower only to the extent of Borrower’s interest in the Property, the Rents and any other collateral given to Lender, and Lender, by accepting the Notes, this Agreement, the Mortgage and the other Loan Documents, agrees that it shall not ▇▇▇ for, seek or demand any deficiency judgment against Borrower or its direct or indirect partners or members in any such action or proceeding under or by reason of or under or in connection with the Notes, this Agreement, the Mortgage or the other Loan Documents except, to the extent permitted by applicable law, for any deficiency judgment that shall be enforced solely against or collected solely from the Property, the Rents or any other collateral given to Lender. The provisions of this Section shall not, however, (a) constitute a waiver, release or impairment of any obligation evidenced or secured by any of the Loan Documents; (b) impair the right of Lender to name Borrower as a party defendant in any action or suit for foreclosure and sale under the Mortgage; (c) affect the validity or enforceability of or any guaranty or indemnity made in connection with the Loan or any of the rights and remedies of Lender thereunder; (d) impair the right of Lender to obtain the appointment of a receiver; (e) impair the enforcement of the Assignment of Leases; (f) constitute a prohibition against Lender to seek a deficiency judgment against Borrower in order to fully realize the security granted by the Mortgage or to commence any other appropriate action or proceeding in order for Lender to exercise its remedies against the Property; or (g) constitute a waiver of the right of Lender to enforce the liability and obligation of Borrower (but not its limited partners), by money judgment or otherwise, to the extent of any loss, damage, cost, expense, liability, claim or other obligation incurred by Lender (including attorneys’ fees and costs reasonably incurred), but excluding consequential damages, arising out of or in connection with (but only to the extent of) the following:

(i) fraud, gross negligence or willful misconduct by Borrower in connection with the Loan;

(ii) any liability under the Environmental Indemnity;

(iii) the misappropriation by Borrower of any Proceeds, Rents or other revenues from the Property, except to the extent such funds are applied to the payment of Operating Expenses of the Property or to pay amounts due under the Loan Documents; and

(iv) the amount of any security deposits collected with respect to the Property which are not delivered to Lender upon a foreclosure of the Property or action in lieu thereof, except to the extent any such security deposits were applied in accordance with the terms and conditions of any of the Leases or pursuant to Applicable Law prior to the occurrence of the Event of Default that gave rise to such foreclosure or action in lieu thereof.

Notwithstanding anything to the contrary in this Agreement or any of the Loan Documents, Lender shall not be deemed to have waived any right which Lender may have under Section 506(a), 506(b), 1111(b) or any other provisions of the U.S. Bankruptcy Code to file a claim for the full amount of the Debt secured by the Mortgage or to require that all collateral shall continue to secure all of the Debt owing to Lender in accordance with the Loan Documents.

Section 11.25 Loan Assignability by Lender. The Loan, and all of Lender’s rights, remedies and privileges hereunder and the other Loan Documents, shall be assignable by Lender at any time and from time to time.

Section 11.26 Counterparts. This Agreement may be executed in several counterparts, each of which may be deemed to be an original and all of which, together, shall constitute one and the same instrument.

Section 11.27 Severance. Lender shall have the right from time to time to sever each Note and the Loan Documents into one or more separate notes, mortgages and other security documents in such denominations as Lender shall determine in its sole discretion, which severed documents shall nevertheless be held by one holder. In connection therewith, Borrower shall execute and deliver to Lender from time to time, at Lender’s sole cost and expense, promptly after the request of Lender, a severance agreement and such other documents as Lender shall reasonably request in order to effect the severance described in the preceding sentence, all in form and substance reasonably satisfactory to Lender and Borrower.
