(d) The Administrative Agent shall maintain accounts in which it shall record (i) the portion and amount of the Term Loan made by each Lender hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of the Term Loan or portion thereof to be prepaid.

(a) From and including the first day of the -------- first Interest Period to, but not including, the last day of the last Interest Period during the term of this Agreement, the entire principal balance of the Term Loan shall, except as specifically set forth in this Agreement to the contrary, bear interest at one of the available Adjusted LIBO Rates plus the ---- Applicable Rate. The available Adjusted LIBO Rates shall consist of a one-month Adjusted LIBO Rate, a two-month Adjusted LIBO Rate, a three-month Adjusted LIBO Rate and a six-month Adjusted LIBO Rate; provided that the only available -------- Adjusted LIBO Rate for the period commencing on the Effective Date and ending on the first to occur of (i) the first Interest Payment Date after the end of the Initial Syndication Period (promptly following the end of which the Administrative Agent shall notify the Borrower) or (ii) the fourth Interest Payment Date during the term of this Agreement, shall be a one-month Adjusted LIBO Rate. From and including the Interest Period commencing on the last day of the Initial Syndication Period, and for each Interest Period thereafter during the term of this Agreement, the Borrower shall have the right to select the applicable available Adjusted LIBO Rate to be added to the Applicable Rate to determine the interest rate applicable to Eurodollar Borrowings, provided such -------- selection is made in writing to the Administrative Agent at least four (4) Business Days prior to the first day of the Interest Period to which such selection is to apply. In the event no such selection is made before such four (4) Business Day period, the Borrower shall be deemed to have irrevocably selected a one-month Adjusted LIBO Rate. (b) Notwithstanding the foregoing, if any principal of or interest on any of the Term Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, (i) such overdue amount shall bear interest, after as well as before judgment, at a rate per annum (the "Default Rate") equal to 4% plus the ------------ Alternate Base Rate until such amount shall be paid in full and (ii) the Borrower shall also pay to the Administrative Agent for the benefit of the Lenders, upon demand, an amount equal to 3% of such unpaid amount as a late payment charge if such amount is not paid within ten (10) days of the date when due, except that such ten (10) day period for application of such late payment ------ charge shall not apply to a late payment of the amount due on the Maturity Date. (c) Accrued interest on each Term Loan shall be payable in arrears on each Interest Payment Date for such Term Loan and on the Maturity Date; provided -------- that (i) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand and (ii) in the event of any repayment or prepayment of the Term Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment. 13 (d) All interest and fees hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent, such determination shall be conclusive absent manifest error and shall be promptly communicated to the Lenders. (e) Notwithstanding anything to the contrary contained herein, at all times that interest is not accruing at an available Adjusted LIBO Rate plus the ---- Applicable Rate pursuant to the provisions of Section 2.05(a), interest shall accrue on the entire principal balance of the Term Loan at the Alternate Base Rate, except that from and after the Maturity Date or sooner acceleration of the ------ Term Loan, the entire principal balance of the Term Loan shall bear interest at the Default Rate. (f) Notwithstanding anything to the contrary set forth in this Section, the Borrower shall have the option from and after the date after which Adjusted LIBO Rates other than the one-month Adjusted LIBO Rate may be selected by the Borrower, to select up to, but not in excess of, three (3) Adjusted LIBO Rates to take effect on any given Interest Payment Date. The Borrower shall make such election by written notice given to the Administrative Agent at least four (4) Business Days prior to each Interest Payment Date, which shall be the last day of a previously selected Adjusted LIBO Rate period, in which notice the Borrower shall specify the Adjusted LIBO Rates so selected by the Borrower and the respective portions of the principal balance of the Term Loan to which such Adjusted LIBO Rates are to respectively pertain, it being agreed that: (i) the minimum portion of the principal balance of the Term Loan to which any such Adjusted LIBO Rate may pertain shall be an amount sufficient to give each Lender at least a $500,000.00 share of each portion of the principal balance of the Term Loan bearing interest at a particular Adjusted LIBO Rate; (ii) each such Adjusted LIBO Rate so selected by the Borrower shall be applicable to the portion of the principal balance of the Term Loan to which it pertains from and including the first day of the applicable Interest Period to, but not including, the last day of the Interest Period applicable to such Adjusted LIBO Rate; and (iii) the Borrower shall not have the right to exercise its option pursuant to this provision as of any given Interest Payment Date if the effect thereof would be to cause more than three (3) different Adjusted LIBO Rate periods to be in effect with respect to the principal balance of the Term Loan at any given time during the term of this Agreement. SECTION 2.06. Alternate Rate of Interest. Notwithstanding the -------------------------- provisions of Section 2.05(a), if prior to the commencement of any Interest Period: (a) the Administrative Agent reasonably and in good faith determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means 14 do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or (b) the Administrative Agent is advised by a Lender or Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lender (or Lenders) of making or maintaining its portion of the Term Loan (or their portions of the Term Loan) for such Interest Period; then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, such portion or portions of the Term Loan shall bear interest at the Alternate Base Rate. SECTION 2.07. Increased Costs. (a) If any Change in Law shall: --------------- (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or (ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Borrowing made by such Lender or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Borrowing (or of maintaining its obligation to make any such Eurodollar Borrowing) or to increase the cost to such Lender or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as such Lender shall determine in good faith to be sufficient to compensate such Lender for such additional costs incurred or reduction suffered, provided that Lender is generally imposing -------- similar charges on its other similarly situated borrowers. (b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of such Lender's holding company, if any, as a consequence of this Agreement or the portion of the Term Loan made by such Lender to a level below that which such Lender or such Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of such Lender's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as such Lender shall determine in good faith to be sufficient to compensate such Lender or such Lender's holding company for any such reduction suffered. Each Lender shall allocate such additional amount or amounts among its customers in good faith and on an equitable basis, and will not charge the Borrower unless it is generally imposing a similar charge on its other similarly situated borrowers. (c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or 15 (b) of this Section, and a brief explanation of such amounts which are due, including reasonably detailed information regarding the method and calculation of such amounts shall be delivered to the Borrower and shall be prima facie ----- ----- evidence that such amounts are due and owing. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof. If the Borrower disputes the amount required to be so paid, such amount shall, nevertheless, be paid on such tenth (10th) Business Day, subject to the Borrower's right to a refund of the disputed amount, if the Borrower's claim for a refund is successful. (d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation; provided that the Borrower shall not be required to -------- compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender's intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs - -------- ------- or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. SECTION 2.08. Break Funding Payments. In the event of (a) the ---------------------- payment of any principal of the Term Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default or any right pursuant to Sections 5.05 or 5.11), (b) the failure to borrow or prepay the Term Loan on the date specified in any notice delivered pursuant hereto or (c) the assignment of the Term Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.11, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. Such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be equal to the portion of the principal balance of the Term Loan being so prepaid, multiplied by a per annum interest rate equal to ---------- -- the difference between the then applicable LIBO Rate and the 360-day equivalent interest yield, as adjusted to reflect interest payments on a monthly basis (the "Reinvestment Rate"), on any U.S. Government Treasury obligations selected by ----------------- the Lender, in its sole and absolute discretion, in an aggregate amount comparable to the portion of the principal balance of the Term Loan being so prepaid, and with maturities comparable to the last day of the period relating to the Adjusted LIBO Rate applicable to the portion of the principal balance of the Term Loan being so prepaid, calculated over a period of time from and --------------- including the date of prepayment to, but not including, the last day of such period. If the LIBO Rate applicable to the portion of the principal balance of the Term Loan being so prepaid is equal to or less than the Reinvestment Rate, no prepayment premium, nor any rebate, shall be due. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section, and a brief explanation of such amounts which are due, including reasonably detailed information regarding the method and calculation of such amounts, shall be delivered to the Borrower by the Administrative Agent and shall be prima facie evidence that such amounts are ----- ----- due, it being agreed that: (i) the calculation of such prepayment premium may be based on any U.S. Government Treasury obligations selected by the Lenders, in their sole and absolute discretion, and (ii) no Lender shall be obligated or required to have actually reinvested the prepaid portion of the principal balance of the Term Loan in any such U.S. Government Treasury obligations as a condition precedent to the Borrower being obligated to pay a prepayment premium calculated as aforesaid. The Borrower shall pay such Lender the amount 16 shown as due on any such certificate within ten (10) Business Days after receipt thereof. If the Borrower disputes the amount required to be so paid, such amount shall, nevertheless, be paid on such tenth (10th) Business Day, subject to the Borrower's right to a refund of the disputed amount, if the Borrower's claim for a refund is successful. SECTION 2.09. Taxes. (a) Any and all payments by or on account of ----- any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the -------- Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. (c) The Borrower shall indemnify the Administrative Agent and each Lender within ten (10) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be prima facie evidence as to ----- ----- the amount of such payment or liability. If the Borrower disputes the amount required to be so paid, such amount shall, nevertheless, be paid on such tenth (10th) Business Day, subject to the Borrower's right to a refund of the disputed amount, if the Borrower's claim for a refund is successful. (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), if, and at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. 17 SECTION 2.10. Payments Generally; Pro Rata Treatment; Sharing of Set- ------------------------------------------------------ offs. (a) The Borrower shall make each payment required to be made by it - ---- hereunder (whether of principal, interest, fees or of amounts payable under Section 2.07, 2.08 or 2.09, or otherwise) prior to 2:00 p.m., New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received on such date after such time may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest or fees thereon. All such payments shall be made to the Administrative Agent at its offices at 380 Madison Avenue, New York, New York, except that payments pursuant to Sections 2.07, 2.08, 2.09 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in U.S. dollars. (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards the payment of fees then due hereunder, (ii) second, toward the payment of interest then due hereunder, and (iii) third, towards payment of principal then due hereunder, with all such payments to be applied ratably among the parties entitled thereto in accordance with the respective Applicable Percentages of the Lenders as applied to the amounts of fees, interest and principal then due to such parties. (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on its respective portion of the Term Loan resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its portion of the Term Loan and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Term Loan of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective portions of the Term Loan; provided that (i) if any such participations are purchased and all or any - -------- portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in the Term Loan to any assignee or participant, other than to the Borrower or any Affiliate thereof (as to which the provisions of this paragraph shall apply). (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders, as the case may be, the amount due. In 18 such event, if the Borrower has not in fact made such payment, then each of the Lenders, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined in accordance with banking industry rules on interbank compensation. (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.10(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under Section 2.10(d) until all such unsatisfied obligations are fully paid. SECTION 2.11. Mitigation Obligations; Replacement of Lenders. (a) ---------------------------------------------- If, pursuant to Section 2.06(b), any Lender's portion of the Term Loan for an Interest Period bears interest at the Alternate Base Rate, or if increased costs are paid to any Lender pursuant to Sections 2.07 or 2.09, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Sections 2.07 or 2.09, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Commitment hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.06(b), 2.07 or 2.09, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) If any Lender requests that interest be paid to it on its portion of the Term Loan pursuant to Section 2.06(b), or if any Lender requests compensation under Section 2.07, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Sections 2.06(b), 2.07 or 2.09, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the -------- prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its share of the Term Loan, accrued interest thereon, accrued fees and all other amounts payable to it hereunder (including any costs incurred under Sections 2.07 and 2.09), from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.07 or payments required to be made pursuant to Sections 2.06(b) or 2.09, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 19 ARTICLE III Representations and Warranties ------------------------------ The Borrower represents and warrants to the Lenders that: SECTION 3.01.

The Borrower will not alter the use of the Mortgaged Property without the prior written consent of the Administrative Agent. (c) The Borrower shall not be deemed to violate the terms and provisions of this Section 5.05 if it is prevented by a tenant from complying herewith; provided, the Borrower promptly pursues all available remedies against such tenant and promptly delivers to the Administrative Agent such evidence of the Borrower's diligent efforts to pursue all remedies against the tenant and such failure to comply does not, in the Borrower's reasonable opinion, endanger the priority of the lien of this Agreement or the Transaction Documents on, or the Borrower's title to, the Mortgaged Property. If the Borrower shall first notify the Administrative Agent in writing of its intention so to do, the Borrower may, at its expense and in its own name and behalf, in good faith contest any statute, ordinance, order, violation or regulation concerning the Mortgaged Property by appropriate legal proceedings; provided, in the event of any such contest, that all necessary steps are taken to protect the Lien of the Mortgage and the other Transaction Documents and that adequate reserves or other appropriate provisions required by GAAP in respect thereof shall have been set aside or made, adequate bonds shall have been obtained, or sufficient funds or other security satisfactory to the Administrative Agent have been provided in a manner satisfactory to the Administrative Agent in all respects, assuring the discharge of the Borrower's obligation under this Section 5.05 with respect to such statutes, ordinances, orders, violations and regulations and provided further that if at any time payment of any assessment or other charge shall become necessary to prevent the loss of priority of the Administrative Agent's Lien interest in the Mortgaged Property, then the Borrower shall immediately pay the sums in sufficient time to prevent such loss of priority of the Administrative Agent's security interest in the Mortgaged Property. (d) The Borrower shall not perform, or suffer to permit, any structural alterations to the Improvements, or perform, or suffer to permit, any alternations which would have a material adverse effect on the building systems of the Improvements, without the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld. (e) The Borrower shall comply with the asbestos maintenance and operation plan of the Borrower for the Mortgaged Property delivered to the Administrative Agent prior to the Effective Date, and shall provide reasonable evidence of compliance therewith to the Administrative Agent from time to time within fifteen (15) days after any request therefor by the Administrative Agent. The Borrower shall use diligent efforts to cause to be delivered an addendum to that certain Phase I 30 Environmental Site Assessment dated March 12, 1997 prepared by Ambient Labs, Inc. (the "Phase I"), to be delivered to the Administrative Agent promptly after the Effective Date, which addendum shall include all additional information necessary to complete the Phase I (including, without limitation, responses to requests made to Governmental Authorities for information relating to the Mortgaged Property). (f) The Borrower shall (i) keep the Mortgaged Property insured with extended coverage against loss or damage by fire, vandalism, malicious mischief and such other hazards as the Administrative Agent shall from time to time reasonably require, in amounts reasonably approved by the Administrative Agent, which amounts shall in no event be less than 100% of the full insurable value of the Improvements and the Equipment (as such terms are defined in the Mortgage) and shall be sufficient to meet all applicable co-insurance requirements, and (ii) will maintain rental and business interruption and rental loss insurance and such other forms of insurance coverage with respect to the Mortgaged Property as the Administrative Agent shall from time to time reasonably require in amounts reasonably approved by the Administrative Agent (including, without limitation, any insurance required to be maintained by the Borrower pursuant to any agreements to which the Mortgaged Property is subject). If the Premises are improved, and any portion thereof is located in a Federally designated "special flood hazard area," in addition to the other policies of insurance required under this paragraph (the "Policies"), a flood insurance policy shall be -------- delivered by the Borrower to the Administrative Agent. If no portion of the Premises is located in a Federally designated "special flood hazard area" such fact shall be substantiated by a certificate in form satisfactory to the Administrative Agent from a licensed surveyor, appraiser or professional engineer or other qualified person satisfactory to the Administrative Agent in accordance with applicable regulations. (g) The Borrower shall at all times comply with and shall cause the Improvements and Equipment on the Mortgaged Property and the use, occupancy, operation, maintenance, alteration, repair and restoration thereof to comply with the terms, conditions, stipulations and requirements of the Policies. All Policies shall be issued by insurers having a minimum policy holders rating of "A" per the latest rating publication of Property and Casualty Insurers by A.M. Best Company and who are lawfully doing business in New York and selected by the Borrower with the approval of the Administrative Agent, which approval shall not be unreasonably withheld or delayed. All Policies shall, with respect to the Premises and the Improvements, contain the standard New York mortgagee non- contribution clause endorsement or an equivalent endorsement and, with respect to the Equipment, contain a lender's loss payable clause endorsement or an equivalent endorsement, all naming the Administrative Agent as the person to which all payments made by the insurer thereunder shall be paid and otherwise in form and substance satisfactory in all respects to the Administrative Agent. Blanket insurance policies shall be acceptable for the purposes of this paragraph, provided that the Borrower provides the Administrative Agent with -------- proof reasonably satisfactory to the Administrative Agent that such blanket policy complies in all respects with the provisions for insurance set forth in this Section 5.05, and that the coverage available with respect to the Mortgaged Property shall at all times be at least equal to the coverage which would be provided under a separate policy covering only the Mortgaged Property. The Borrower shall pay the premiums for the Policies as the same become due and payable. At the request of the Administrative Agent, the Borrower will deliver the Policies to the Administrative Agent. Not later than thirty (30) days prior to the 31 expiration date of each of the Policies, the Borrower will deliver to the Administrative Agent a renewal policy or policies marked "premium paid" or accompanied by other evidence of payment of premium satisfactory to the Administrative Agent. If at any time any insurance required hereunder is not in full force and effect, the Administrative Agent shall have the right, without notice to the Borrower, to take such action as the Administrative Agent deems reasonably necessary to protect its interest in the Mortgaged Property, including, without limitation, the obtaining of such insurance coverage as the Administrative Agent deems reasonably appropriate, and all expenses incurred by the Administrative Agent in connection with such action or in obtaining such insurance and keeping it in effect, with interest thereon at the Default Rate, shall be paid by the Borrower to the Administrative Agent within five (5) Business Days after demand and until paid shall be secured by the Liens of the Transaction Documents. (h) If the Mortgaged Property shall be damaged or destroyed, in whole or in part, by fire or other property hazard or casualty, the Borrower shall give reasonably prompt notice thereof to the Administrative Agent. Except as otherwise hereinafter specifically provided to the contrary, sums paid to the Administrative Agent by any insurer may be retained and applied by the Administrative Agent toward payment of the Term Loan, whether or not then due and payable, in such order, priority and proportions as the Administrative Agent in its discretion shall deem proper or, at the discretion of the Administrative Agent, the same may be paid, either in whole or in part, to the Borrower for such purposes as the Administrative Agent shall designate. If the Administrative Agent shall receive and retain such insurance proceeds, the Liens of the Transaction Documents shall be reduced only by the amount thereof received and retained by the Administrative Agent and actually applied by the Administrative Agent in reduction of the Term Loan. The Administrative Agent shall not be obligated to see to the proper application of insurance money paid over to the Borrower, and if the Administrative Agent receives and retains any insurance proceeds, the Liens of the Transaction Documents shall be affected only by a reduction of the amount of said Liens by the amount of such insurance money so received and retained by the Administrative Agent. Nevertheless, if ------------ prior to the receipt by the Administrative Agent of any insurance proceeds, the Mortgaged Property shall have been sold on foreclosure of the Mortgage, as between the Borrower and the Administrative Agent, the Administrative Agent shall have the right to receive said insurance proceeds, and the Borrower shall pay over to the Administrative Agent said insurance proceeds as, if and when the Borrower receives same, to the extent of (i) any deficiency found to be due upon such sale, with legal interest thereon, whether or not a deficiency judgment on the Note and the Mortgage shall have been sought or recovered, and (ii) the attorney's fees, costs and disbursements incurred by the Administrative Agent in connection with the collection of such insurance proceeds. All remaining right, title and interest of the Borrower in and to all policies of insurance required by this Section 5.05 shall inure to the benefit of and pass to the successor-in- interest to the Borrower or the purchaser or grantee of the Mortgaged Property. The Borrower hereby appoints the Administrative Agent its attorney-in-fact to endorse any checks, drafts or other instruments representing any proceeds of such insurance, whether payable by reason of loss thereunder or otherwise; provided the Administrative Agent shall hold such funds in accordance with the terms of this Agreement. The provisions of subsection 4 of Section 254 of the Real Property Law of New York covering the insurance of buildings against loss by fire shall not apply to the Mortgage, this Agreement or any other Transaction Document. 32 (i) If the Mortgaged Property shall be damaged or destroyed, in part, by fire or other casualty, the Administrative Agent shall, in accordance with the provisions of this Section 5.05 herein set forth, but subject to clause (m) below, make the net amount of all insurance proceeds received by the Administrative Agent pursuant to the provisions of this Agreement as a result of such damage or destruction, after deduction of its reasonable costs and expenses (including, but not limited to, reasonable counsel fees), if any, in collecting the same (the "Net Proceeds") available for the repair and restoration of the ------------ Mortgaged Property, provided that: (i) no Default shall have occurred and shall be continuing; (ii) the Borrower shall commence the repair and restoration of the Mortgaged Property, as nearly as possible to the condition the Mortgaged Property was in immediately prior to such fire or other casualty, with such alterations as may be reasonably approved by the Administrative Agent, as soon as reasonably practicable (but in no event later than ninety (90) days after such damage or destruction occurs) and shall diligently and continuously pursue the same to satisfactory completion; (iii) the Administrative Agent shall be satisfied that any operating deficits which will be incurred with respect to the Mortgaged Property as a result of the occurrence of any such fire or other casualty will be covered out of the Net Proceeds, rental loss insurance, business interruption insurance or by other funds of the Borrower; (iv) the Administrative Agent shall be satisfied that the repair and restoration of the Mortgaged Property (a) will be completed on or before the earlier to occur of (x) six (6) months prior to the Maturity Date, and (y) the earliest date required for such completion under the terms of any Leases which will or are required to remain in effect subsequent to the occurrence of such fire or other casualty, and (b) is capable of being completed within a period of twelve (12) months or less; (v) The Borrower and the Guarantor shall each execute and deliver to the Administrative Agent a joint and several, personal recourse completion guaranty in form and substance satisfactory to the Administrative Agent and its counsel pursuant to the provisions of which they shall jointly and severally guaranty to the Administrative Agent the lien-free completion by the Borrower of the repair and restoration of the Mortgaged Property in accordance with the provisions of this Section 5.05 and within such time as shall be required pursuant to any Leases which are not terminated as a consequence of such damage and destruction. (j) The Net Proceeds shall be held by the Administrative Agent in an interest bearing special account, and until disbursed in accordance with the provisions of this Section 5.05, shall constitute additional security for the payment of the Term Loan. The Net Proceeds, together with interest earned thereon, shall be disbursed by the Administrative Agent to, or as directed by, the Borrower from time to time during the course of the repair and restoration of the Mortgaged Property, upon receipt of evidence satisfactory to the Administrative Agent that (i) all materials installed and work and labor performed (except to the extent that they are to be paid for out of the 33 requested disbursement) in connection with the repair and restoration of the Mortgaged Property have been paid for in full, and (ii) there exist no notices of pendency, stop orders, mechanic's or materialman's liens or notices of intention to file same, or any other liens or encumbrances of any nature whatsoever on the Mortgaged Property arising out of the repair and restoration of the Mortgaged Property which have not either been fully bonded to the satisfaction of the Administrative Agent and discharged of record or in the alternative fully insured over to the satisfaction of the Administrative Agent by the title company insuring the Liens of the Transaction Documents. (k) The repair and restoration of the Mortgaged Property shall be done and completed by the Borrower in an expeditious and diligent fashion and in compliance with all applicable governmental laws, rules and regulations (including, without limitation, all applicable Environmental Laws), and all plans and specifications required in connection with the repair and restoration of the Mortgaged Property shall be subject to the reasonable prior review and acceptance in all respects by the Administrative Agent and by an independent consulting engineer selected by the Administrative Agent (hereinafter referred to in this paragraph as the "Casualty Consultant"), which Casualty Consultant ------------------- shall be subject to the reasonable prior approval of the Borrower. Upon the occurrence and during the continuance of a Default or an Event of Default, the Administrative Agent shall have the use of such plans and specifications and all permits, licenses and approvals required or obtained in connection with the repair and restoration of the Mortgaged Property. The identity of the contractors, subcontractors and materialmen engaged in the repair and restoration of the Mortgaged Property, as well as the contracts under which they have been engaged, shall be subject to the reasonable prior review and acceptance by the Administrative Agent and the Casualty Consultant. Failure of the Administrative Agent or the Casualty Consultant to approve or disapprove (with specific reasons for any such disapprovals) the plans and specifications, or the contractors, subcontractors and materialmen engaged in the repair and restoration of the Mortgaged Property, as well as the contracts under the which they have been engaged, within five (5) Business Days of receiving a written request from the Borrower for such approval, if such plans and specifications relate to restoration of 75,000 square feet of space or less in the Mortgaged Property, and within twenty (20) Business Days, if such plans and specifications relate to more than 75,000 square feet of space in the Mortgaged Property, shall be deemed the approval by the Administrative Agent or the Casualty Consultant, or both, as the case may be. All costs and expenses incurred by the Administrative Agent in connection with making the Net Proceeds available for the repair and restoration of the Mortgaged Property including, without limitation, reasonable counsel fees and the Casualty Consultant's reasonable fees, shall be paid by the Borrower. (l) In no event shall the Administrative Agent be obligated to make disbursements of the Net Proceeds in excess of an amount equal to the costs actually incurred from time to time for work in place as part of the repair and restoration of the Mortgaged Property, as certified by the Casualty Consultant, minus the Casualty Retainage. The term "Casualty Retainage" as used in this - ----- ------------------ paragraph shall mean an amount equal to 10% of the costs actually incurred for work in place as part of the repair and restoration of the Mortgaged Property, as certified by the Casualty Consultant. The Casualty Retainage shall in no event, and notwithstanding anything to the contrary hereinabove set forth in this paragraph, be less than the amount actually held back by the Borrower from contractors, subcontractors and materialmen engaged in the making of the repair and restoration of the Mortgaged Property. The Administrative Agent shall not be obligated to make disbursements of the Net 34 Proceeds more frequently than once every thirty (30) days. The Casualty Retainage shall not be released until the Casualty Consultant certifies to the Administrative Agent that the repair and restoration of the Mortgaged Property has been completed in accordance with the provisions of this paragraph and that all approvals necessary for the re-occupancy and use of the Mortgaged Property have been obtained from all appropriate Governmental Authorities, and the Administrative Agent receives evidence satisfactory to the Administrative Agent that the costs of the repair and restoration of the Mortgaged Property has been paid in full or will be paid in full out of the Casualty Retainage, provided, however, that the Administrative Agent will release the portion of the Casualty Retainage being held with respect to any contractor, subcontractor or materialman engaged in the repair and restoration of the Mortgaged Property as of the date upon which the Casualty Consultant certifies to the Administrative Agent that such contractor, subcontractor or materialman has satisfactorily completed all work and has supplied all materials in accordance with the provisions of such contractor's, subcontractor's or materialman's contract, and such contractor, subcontractor or materialman delivers such lien waivers and evidence of payment in full of all sums due to such contractor, subcontractor or materialman as may be reasonably requested by the Administrative Agent or by the title company insuring the Liens of the Transaction Documents. If required by the Administrative Agent, the release of any such portion of the Casualty Retainage shall be approved by the surety company, if any, which has issued a payment or performance bond with respect to such contractor, subcontractor or materialman. (m) Notwithstanding anything to the contrary contained in this Section 5.05, the Administrative Agent shall not be obligated to, and shall not without the consent of the Required Lenders, make Net Proceeds available for the repair and restoration of the Mortgaged Property in accordance with the provisions of this Section 5.05 if more than 50% of the Mortgaged Property have been damaged or destroyed by such fire or other casualty, unless, in addition to all of the other terms and conditions set forth in this Section 5.05, including, without limitation, subparagraph (i) above, Leases covering 75% of the rentable area of the Improvements shall remain in full force and effect notwithstanding the occurrence of such damage and destruction. Determinations of the anticipated time necessary for the repair and restoration of the Improvements pursuant to Sections 5.05 and 5.11 shall be made by the Casualty Consultant, whose determination shall be binding and conclusive, absent manifest error. (n) Notwithstanding anything to the contrary contained in this Section 5.05, if the Net Proceeds and the costs of completing the repair and restoration of the Mortgaged Property shall be equal to or less than $7,500,000, the Net Proceeds will be disbursed by the Administrative Agent to the Borrower upon receipt, provided that no Default shall have occurred and shall be continuing, and the Borrower delivers to the Administrative Agent a written undertaking to expeditiously commence and to satisfactorily complete with due diligence the repair and restoration of the Mortgaged Property. In the event the circumstances in clause (i) shall apply, and the Administrative Agent shall elect not to make the Net Proceeds available to the Borrower for restoration, the Borrower shall terminate any Leases which it has a right to terminate and with respect to which the Administrative Agent may be bound to make such proceeds available for restoration pursuant to a non-disturbance or similar agreement, and the Borrower hereby irrevocably appoints the Administrative Agent as its attorney-in-fact for the purpose of exercising the termination of any such Leases under such circumstances. 35 (o) If at any time the Net Proceeds or the undisbursed balance thereof shall not, in the opinion of the Administrative Agent and the Casualty Consultant, be sufficient to pay in full the balance of the costs which will be incurred in connection with the completion of the repair and restoration of the Mortgaged Property, the Borrower shall deposit the deficiency (the "Net Proceeds ------------ Deficiency") with the Administrative Agent before any further disbursement of - ---------- the Net Proceeds shall be made, which Net Proceeds Deficiency deposit shall be held by the Administrative Agent in an interest bearing special account, and shall be disbursed, together with interest earned thereon, for costs actually incurred in connection with the repair and restoration of the Mortgaged Property on the same conditions applicable to the disbursement of the Net Proceeds, and until so disbursed pursuant to this paragraph (n) shall constitute additional security for the payment of the Term Loan. Upon the occurrence of an Event of Default, the Administrative Agent shall have the right to apply the undisbursed balance of any Net Proceeds and any Net Proceeds Deficiency deposit, together with interest thereon, to the payment of the Term Loan in such order, priority and proportions as the Administrative Agent shall deem to be appropriate in its discretion. The excess, if any, of the Net Proceeds and the remaining balance, if any, of the Net Proceeds Deficiency deposit, together with interest thereon, after the Casualty Consultant certifies to the Administrative Agent that the repair and restoration of the Mortgaged Property has been completed in accordance with the provisions of this paragraph, and the receipt by the Administrative Agent of evidence satisfactory to the Administrative Agent that all costs incurred in connection with the repair and restoration have been paid in full, shall be remitted to the Borrower. (p) All costs of the repair and restoration of the Mortgaged Property in excess of the Net Proceeds shall be paid for by the Borrower. If the Administrative Agent shall receive and retain insurance proceeds, the Liens of the Transaction Documents shall be reduced only by the amount thereof received and retained by the Administrative Agent and actually applied by the Administrative Agent in reduction of the Term Loan. SECTION 5.06. Books and Records; Inspection Rights. (a) The ------------------------------------ Borrower will keep and maintain, and will cause its Affiliates to keep and maintain, on a fiscal year basis in accordance with GAAP consistently applied, proper and accurate books, records and accounts reflecting all of the financial affairs of the Borrower and its Affiliates, including without limitation, all items of income and expense in connection with the operation of the Mortgaged Property and in connection with all services, equipment and furnishings provided in connection with the operation of the Mortgaged Property, whether such income or expense be realized by the Borrower or by any other Person excepting lessees unrelated to and unaffiliated with the Borrower who have leased from the Borrower portions of the Mortgaged Property for the purpose of occupying the same. The Administrative Agent and each Lender shall have the right from time to time at all times during normal business hours and upon reasonable prior notice, to examine such books, records and accounts at the offices of the Borrower and its Affiliates, or any other Person maintaining such books, records and accounts, and to make copies or extracts thereof as the Administrative Agent or any Lender shall desire. The Borrower shall be, and shall cause its Affiliates, officers and independent accountants to be, available to discuss such financial affairs, books and records with the Administrative Agent's and any Lender's representatives, at reasonable times and as often as reasonably requested. 36 (b) The Administrative Agent and each Lender, and their representatives, shall be permitted to inspect the Mortgaged Property, at reasonable times and as often as reasonably requested, and the Borrower shall cooperate with the Administrative Agent and any Lender in connection with requested inspections of tenanted areas in the Improvements. SECTION 5.07. Further Assurances. The Borrower agrees, at its ------------------ expense, that at any time it will, and will cause the Guarantor to, promptly execute and deliver all instruments and documents, and take all further action that the Administrative Agent may reasonably request, in order to perfect any security interest granted under the Transaction Documents or to enable the Administrative Agent to exercise and enforce its rights and remedies hereunder and under the Transaction Documents. SECTION 5.08. Use of Proceeds. The proceeds of the Term Loan will be --------------- used solely for the acquisition of the Mortgaged Property and no part of such proceeds shall, in any event, be used for any purpose, whether directly or indirectly, that entails a violation of any of the Regulations of the Board, including Regulations G, U and X. SECTION 5.09. Management. (a) The Mortgaged Property shall at all ---------- times be managed by the Borrower, and the fees retained by the Borrower therefor shall be subject to the approval of the Administrative Agent, which shall not be unreasonably withheld if such rates are commercially reasonable and, in any event, shall not exceed 1% of the gross rental income collected if management shall be by the Borrower or an Affiliate of the Borrower. The Borrower acknowledges and agrees that its right to receive such fees are subordinate to any and all sums due to the Administrative Agent and the Lenders under the Transaction Documents. If the existing management by the Borrower shall cease with the approval of the Administrative Agent, which approval shall not be unreasonably withheld, then the Borrower shall at all times thereafter retain or cause to be retained, at its expense, a qualified, nationally recognized commercial property manager that has a significant presence in the New York metropolitan area and that is, in the judgment of the Administrative Agent, qualified to act as such to operate and manage the Mortgaged Property and the Leases pursuant to the terms and conditions of a management agreement or agreements satisfactory to the Administrative Agent in its reasonable discretion. Any future management agreements entered into in accordance with this Section 5.09 is hereinafter each referred to as a "Management Agreement". -------------------- The Borrower warrants and represents that the existing management by the Borrower shall be terminable, at the election of the Administrative Agent, upon the occurrence and continuance of an Event of Default, and each Management Agreement shall be, (i) terminable with respect to the Mortgaged Property upon not less than sixty (60) days' prior notice by the Borrower, without cause or at will upon thirty (30) days' prior notice and without cause upon a transfer of the Mortgaged Property to the Administrative Agent or its designee as a result of a foreclosure, deed in lieu of foreclosure or otherwise, in each case, without payment of any premium or penalty, and (ii) assignable to the Administrative Agent or its designee in the event the Administrative Agent shall succeed to the interest of the Borrower in the Mortgaged Property pursuant to the events described in clause (i) above. The Borrower shall (A) pay all sums required to be paid by it for management, whether to itself or under a Management Agreement (except to the extent the Borrower shall contest in good faith such payment), (B) diligently perform and observe all of the material terms, covenants and conditions of such Management Agreements on its part to be performed and observed to the end 37 that all things shall be done which are necessary to keep unimpaired its rights under such Management Agreements, except to the extent the Borrower shall contest in good faith such terms, covenants and conditions, (C) diligently enforce its rights under such Management Agreements in a commercially reasonable manner so as to require full and faithful performance by the related property manager of its obligations under such Management Agreements, (D) promptly provide the Administrative Agent with a copy of any written notice to the Borrower or the related property manager of any material default in the performance or observance of any of the material terms, covenants or conditions of any of such Management Agreements, and (E) cause any Affiliate which is the property manager, and use reasonable efforts to cause any unaffiliated Person which is the property manager, under each of the Management Agreements to comply with the terms and conditions of this Agreement and the Transaction Documents (it being agreed that in the event of any conflict between the terms of any Management Agreement, and this Agreement or any other Transaction Document, the terms of this Agreement and the other Transaction Documents shall control). (b) If the Borrower defaults in the performance or observance of any material term, covenant or condition of any Management Agreement on the part of the Borrower to be performed or observed, then, if such default is not remedied within twenty (20) days after the Borrower's receipt of written notice of the occurrence of such default (or to the extent such default cannot with diligence be remedied within such twenty (20) day period, the Borrower does not commence and thereafter proceed with due diligence to cure such default), then, without limiting the generality of the other provisions of this Agreement, and without waiving or releasing the Borrower from any of its obligations hereunder, the Administrative Agent shall have the right, but shall be under no obligation, to pay any sums or take any action as may be appropriate to cause such term, covenant or condition of such Management Agreement on the part of the Borrower to be promptly performed or observed on behalf of the Borrower, to the end that the rights of the Borrower in, to and under such Management Agreement shall be kept unimpaired and free from default. The Borrower shall reimburse the Administrative Agent on demand for any such sums paid by the Administrative Agent, with interest thereon at the Default Rate from the date such sum was expended until fully reimbursed, which sum and interest shall be additional indebtedness under the Term Loan and secured by the Transaction Documents. (c) Any substitute property manager engaged after the date hereof shall be subject to the approval of the Required Lenders, which approval shall not be unreasonably withheld provided such substitute property manager and the Substitute Management Agreement satisfies the requirements of paragraph (a) above. (d) The Management Agreements shall not be (i) amended or modified in any material respect without the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, or (ii) terminated without the prior written consent of the Required Lenders, which consent shall not be unreasonably withheld if a substitute property manager satisfying the approval requirements of paragraph (c) above has been obtained by the Borrower. The Borrower shall obtain a replacement property manager meeting the approval requirements set forth in paragraph (c) above prior to exercising any right to terminate the then effective Management Agreement unless such termination arises by reason of a default by the property manager under the then effective 38 Management Agreement and the Borrower determines in its reasonable judgment that the failure of the Borrower to remove such property manager would have a material adverse effect on the Mortgaged Property or the Borrower, in which case the Borrower shall replace the property manager promptly following such termination. The Management Agreements shall be collaterally assigned to the Administrative Agent pursuant to collateral assignments in form and substance reasonably acceptable to the Administrative Agent. Each Substitute Management Agreement and the manager thereunder shall be subject to the approval of the Required Lenders, which approval shall not be unreasonably withheld, and each Substitute Management Agreement shall be (A) terminable by the Borrower (1) upon not less than sixty (60) days' prior notice without cause and (2) at will upon 30 days' prior notice and without cause upon a transfer of the Mortgaged Property to the Administrative Agent or its designee as a result of a foreclosure, deed-in-lieu of foreclosure or otherwise, in each case, without payment of any premium or penalty and (B) assignable to the Administrative Agent or its designee in the event the Administrative Agent or its designee shall succeed to the interest of the Borrower in the Mortgaged Property as a consequence of the events described in clause (2) above. The amount of the fees payable by the Borrower under such Substitute Management Agreements may vary from those payable under the Existing Management Agreement being substituted so long as such fees are not higher than current market rates for managers of properties of similar character and nature as the Mortgaged Property. (e) Notwithstanding any provision of this Agreement or the Transaction Documents to the contrary, at any time an Event of Default exists, the Required Lenders shall have the option to direct the Borrower to terminate any or all of the then existing Management Agreements and to replace the property management (and upon such direction, the Borrower shall terminate and replace such Management Agreements and property managers, as the case may be); provided, that in such event, the replacement of the property managers and - -------- Management Agreements directed by the Required Lenders shall be consistent with the requirements of this Section 5.09. SECTION 5.10. Net Cash Flow Shortfall. The Borrower shall provide ----------------------- all necessary funds to the operating account of the Mortgaged Property at the end of each calendar month, equal to the Net Cash Flow Shortfall (as such term is defined in the Joint and Several Guaranty and Agreement (Net Cash Flow Shortfall), of even date herewith, made by the Borrower and the Guarantor), for such month, and shall use such funds and other funds available to it to pay all expenses of the Mortgaged Property as and when due. The Borrower shall provide the Administrative Agent with such evidence thereof as the Administrative Agent may from time to time reasonably request. SECTION 5.11. Condemnation. (a) Notwithstanding any taking by any ------------ public or quasi-public authority through eminent domain or otherwise, the Borrower shall continue to pay the Term Loan at the time and in the manner provided for its payment in this Agreement and the Transaction Documents, and the Term Loan shall not be reduced until any award or payment therefor shall have been actually received and applied by the Administrative Agent to the discharge of the Term Loan. Except as otherwise hereinafter specifically provided to the contrary, the Administrative Agent may apply the entire amount of any such award or payment to the discharge of the Term Loan whether or not then due and payable in such order, priority and proportions as the Administrative Agent in its discretion shall deem proper. The Administrative Agent shall not be obligated to see to 39 the proper application of any award or payment paid over to the Borrower, and if the Administrative Agent receives and retains such award or payment, the Lien of the Mortgage shall be affected only by a reduction of the amount of said Lien by the amount of such award or payment so received and retained by the Administrative Agent. Nevertheless, if the Mortgaged Property is sold, through foreclosure or otherwise, prior to the receipt by the Administrative Agent of such award or payment, as between the Borrower and the Administrative Agent, the Administrative Agent shall have the right, whether or not a deficiency judgment on the Note and the Mortgage shall have been sought, recovered or denied, to receive such award or payment, or a portion thereof sufficient to pay the Term Loan, whichever is less, and the Borrower shall pay over to the Administrative Agent said award or payment as, if and when the Borrower receives same, to the extent of (i) any deficiency found to be due upon such sale, with interest thereon, whether or not a deficiency judgement on the Note and the Mortgage shall have been sought or recovered or denied, and (ii) the attorney's fees, costs and disbursements incurred by the Administrative Agent in connection with the collection of such award or payment. It is the express intent and agreement of the parties that in the event of any such taking, the Administrative Agent shall receive interest at the rate set forth in this Agreement up to and including the date of actual payment in full of the Term Loan, provided that the rate set forth in this Agreement is higher than the statutory rate, and the Borrower (or any assignee or successor in interest thereof) shall therefore be responsible to pay to the Administrative Agent an amount equal to the entire difference between the amount of interest received by the Administrative Agent from the condemning authority (or to which the Administrative Agent is entitled under the condemnation interest statute) and the interest rate it would have been paid hereunder from the date of vesting of title in such condemnation to the date of actual payment, except where the statutory rate on the condemnation award is higher than the rate set forth in this Agreement, in which event, the Administrative Agent shall be entitled to the statutory rate. The Borrower shall file and prosecute its claim or claims for any such award or payment in good faith and with due diligence and cause the same to be collected and paid over to the Administrative Agent. The Borrower hereby irrevocably authorizes and empowers the Administrative Agent, in the name of the Borrower or otherwise, to collect and receipt for any such award or payment and to file and prosecute such claim or claims. Although it is hereby expressly agreed that the same shall not be necessary in any event, the Borrower shall, upon demand of the Administrative Agent, make, execute and deliver any and all assignments and other instruments sufficient for the purpose of assigning any such award or payment to the Administrative Agent, free and clear of any encumbrances of any kind or nature whatsoever. (b) If less than all the Mortgaged Property is taken by any public or quasi-public authority through eminent domain or otherwise, the Administrative Agent shall, in accordance with the provisions of this clause (b), make the portion of the aggregate award or payment received by the Administrative Agent pursuant to the provisions of this Agreement as a result of such taking, after deduction of its reasonable costs and expenses (including, but not limited to, reasonable counsel fees), if any, in collecting the same (the "Net Restoration --------------- Award") available for the repair and restoration of the Mortgaged Property, - ----- provided that: (i) no Default shall have occurred and shall be continuing; (ii) the Borrower shall commence the repair and restoration of the Mortgaged Property, as nearly as possible to the condition the Mortgaged Property was in immediately 40 prior to such taking, with such alterations as may be reasonably approved by the Administrative Agent, as soon as reasonably practicable (but in no event later than ninety (90) days after the earlier to occur of the date of such taking or the date the condemnation award or payment is settled) and shall diligently and continuously pursue the same to satisfactory completion; (ii) the Administrative Agent shall be satisfied that any operating deficits which will be incurred with respect to the Mortgaged Property as a result of the occurrence of any such taking will be covered out of the Net Restoration Award, business interruption and rental loss insurance or by other funds of the Borrower; (iv) the Administrative Agent shall be satisfied that the repair and restoration of the Mortgaged Property (a) will be completed on or before the earlier to occur of (x) six (6) months prior to the maturity date of the Term Loan, and (y) the earliest date required for such completion under the terms of any of the Leases which will or are required to remain in effect subsequent to such taking, and (b) is capable of being completed within a period of twelve (12) months or less; (v) the Borrower and the Guarantor shall execute and deliver to the Administrative Agent a personal recourse completion guaranty in form and substance satisfactory to the Administrative Agent and its counsel pursuant to the provisions of which they shall jointly and severally guaranty to the Administrative Agent the lien-free completion by the Borrower of the repair and restoration of the Mortgaged Property in accordance with the provisions of this Section 5.11 and prior to such time as shall be required pursuant to any Lease which is not terminated as a consequence of such condemnation. (c) The Net Restoration Award shall be held by the Administrative Agent in an interest bearing special account, and until disbursed in accordance with the provisions of this Section 5.11, shall constitute additional security for the payment of the Term Loan. The Net Restoration Award, shall be disbursed by the Administrative Agent to, or as directed by, the Borrower from time to time during the course of the repair and restoration of the Mortgaged Property, upon receipt of evidence satisfactory to the Administrative Agent that (i) all materials installed and work and labor performed (except to the extent that they are to be paid for out of the requested disbursement) in connection with the repair and restoration of the Mortgaged Property have been paid for in full, and (ii) there exist no notices of pendency, stop orders, mechanic's or materialman's liens or notices of intention to file same, or other liens or encumbrances of any nature whatsoever on the Mortgaged Property arising out of the repair and restoration of the Mortgaged Property which have not either been fully bonded to the satisfaction of the Administrative Agent and discharged of record or in the alternative fully insured over to the satisfaction of the Administrative Agent by the title company insuring the Lien of the Mortgage. (d) The repair and restoration of the Mortgaged Property shall be done and completed by the Borrower in an expeditious and diligent fashion and in compliance with all applicable governmental laws, rules and regulations (including, without limitation, all applicable Environmental Laws), and all plans and specifications required in connection with the repair and restoration of the 41 Mortgaged Property shall be subject to the reasonable prior review and acceptance in all respects by the Administrative Agent and by an independent consulting engineer selected by the Administrative Agent (hereinafter referred to in this paragraph as the "Restoration Consultant"), which Restoration ---------------------- Consultant shall be subject to the reasonable prior approval of the Borrower. Upon the occurrence and during the continuance of a Default or an Event of Default, the Administrative Agent shall have the use of such plans and specifications and all permits, licenses and approvals required or obtained in connection with the repair and restoration of the Mortgaged Property. The identity of the contractors, subcontractors and materialmen engaged in the repair and restoration of the Mortgaged Property, as well as the contracts under which they have been engaged, shall be subject to the reasonable approval, review and acceptance by the Administrative Agent and the Restoration Consultant. Failure of the Administrative Agent or the Restoration Consultant to approve or disapprove (with specific reasons for any such disapprovals) the plans and specifications, or the contractors, subcontractors and materialmen engaged in the repair and restoration of the Mortgaged Property, as well as the contracts under the which they have been engaged, within seven (7) Business Days of receiving a written request from the Borrower for such approval, shall be deemed the approval by the Administrative Agent or the Restoration Consultant, or both, as the case may be. All costs and expenses incurred by the Administrative Agent in connection with making the Net Restoration Award available for the repair and restoration of the Mortgaged Property including, without limitation, appraisal fees, reasonable counsel fees and the Restoration Consultant's reasonable fees, shall be paid by the Borrower. (e) In no event shall the Administrative Agent be obligated to make disbursements of the Net Restoration Award in excess of an amount equal to the costs actually incurred for work in place as part of the repair and restoration of the Mortgaged Property, as certified by the Restoration Consultant, minus the ----- Condemnation Retainage. The term "Condemnation Retainage" as used in this ---------------------- paragraph shall mean an amount equal to 10% of the costs actually incurred for work in place as part of the repair and restoration of the Mortgaged Property, as certified by the Restoration Consultant. The Condemnation Retainage shall in no event, and notwithstanding anything to the contrary hereinabove set forth in this paragraph, be less than the amount actually held back by the Borrower from contractors, subcontractors and materialmen engaged in the making of the repair and restoration of the Mortgaged Property. The Administrative Agent shall not be obligated to make disbursements of the Net Restoration Award more frequently than once every thirty (30) days. The Condemnation Retainage shall not be released until the Restoration Consultant certifies that the repair and restoration of the Mortgaged Property has been completed in accordance with this paragraph and that all approvals necessary for the re-occupancy and use of the Mortgaged Property has been obtained from all appropriate Governmental Authorities, and the Administrative Agent receives evidence satisfactory to the Administrative Agent that the costs of the repair and restoration of the Mortgaged Property have been paid in full or will be paid in full out of the Condemnation Retainage, provided, however, that the Administrative Agent will release the portion of the Condemnation Retainage being held with respect to any contractor, subcontractor or materialman engaged in the repair and restoration of the Mortgaged Property as of the date upon which the Restoration Consultant certifies to the Administrative Agent that such contractor, subcontractor or materialman has satisfactorily completed all work and has supplied all materials in accordance with the provisions of such contractor's, subcontractor's or materialman's contract, and such contractor, subcontractor or materialman delivers such lien waivers and evidence of payment in full of all sums due to such 42 contractor, subcontractor or materialman as may be reasonably requested by the Administrative Agent or by the title company insuring the Liens of the Transaction Documents. If required by the Administrative Agent, the release of any such portion of the Condemnation Retainage shall be approved by the surety company, if any, which has issued a payment or performance bond with respect to such contractor, subcontractor or materialman. (f) If at any time the Net Restoration Award, or the undisbursed balance thereof, shall not, in the opinion of the Administrative Agent and the Restoration Consultant, be sufficient to pay in full the balance of the costs which will be incurred in connection with the completion of the repair and restoration of the Mortgaged Property, the Borrower shall deposit the deficiency (the "Net Award Deficiency") with the Administrative Agent before any further -------------------- disbursement of the Net Restoration Award shall be made, which Net Award Deficiency deposit shall be held by the Administrative Agent in an interest bearing special account, and shall be disbursed, together with interest earned thereon, for costs actually incurred in connection with the repair and restoration of the Mortgaged Property on the same conditions applicable to the disbursement of the Net Restoration Award, and, until so disbursed pursuant to this paragraph (f), shall constitute additional security for the payment of the Term Loan. Upon the occurrence of an Event of Default, the Administrative Agent shall have the right to apply the undisbursed balance of any Net Restoration Award and Net Award Deficiency deposit, together with interest thereon, to the payment of the Term Loan in such order, priority and proportions as the Administrative Agent shall deem to be appropriate in its discretion. The Excess, if any, of the Net Restoration Award and the remaining balance, if any, of the Net Award Deficiency deposit, together with interest thereon, after the Restoration Consultant certifies to the Administrative Agent that the repair and restoration of the Mortgaged Property has been completed in accordance with the provisions of this paragraph, and the receipt by the Administrative Agent of evidence satisfactory to the Administrative Agent that all costs incurred in connection with the repair and restoration have been paid in full, shall be remitted to the Lender, unless the Borrower shall request Lender to obtain, at Borrower's expense, an appraisal of the Mortgaged Property which indicates that the value of the Mortgaged Property before such taking is equal to or greater than the value of the Mortgaged Property after such taking and restoration. (g) Notwithstanding anything to the contrary contained in this Section 5.11, (i) the Administrative Agent shall not be obligated to, and shall not without the consent of the Required Lenders, make the Net Restoration Award available for the repair and restoration of the Mortgaged Property in accordance with the provisions of this Section 5.11, if more than 50% of the Mortgaged Property have been damaged or destroyed by such fire or other casualty, unless, in addition to all of the other terms and conditions set forth in this section 5.11, including, without limitation, subparagraph (b) above, Leases covering 75% of the rentable area of the Improvements shall remain in full force and effect notwithstanding the occurrence of such damage and destruction. (h) Notwithstanding anything to the contrary contained in this Section 5.11, if the Net Restoration Award and the costs of completing the repair and restoration of the Mortgaged Property shall be equal to or less than $7,500,000, the Net Restoration Award will be disbursed by the Administrative Agent to the Borrower upon receipt, provided that no Default shall have occurred and shall be continuing, and the Borrower delivers to the Administrative Agent a written undertaking to 43 expeditiously commence and to satisfactorily complete with due diligence the repair and restoration of the Mortgaged Property. (i) All costs of the repair and restoration of the Mortgaged Property in excess of the Net Restoration Award shall be paid for by the Borrower. SECTION 5.12. Leases and Rents. (a) Subject to the terms of this ---------------- Section 5.12, the Administrative Agent waives the right to enter the Mortgaged Property for the purpose of collecting the Rents, and grants the Borrower the right to collect the Rents and to let the Mortgaged Property or any part thereof. The Borrower shall hold the Rents, or an amount sufficient to discharge all current sums due on the Term Loan, in trust for use in payment of the Term Loan. The right of the Borrower to collect the Rents and to let the Mortgaged Property or any part thereof may be revoked by the Administrative Agent with the approval of the Required Lenders upon the occurrence and during the continuance of any Event of Default and thereafter the Administrative Agent with the approval of the Required Lenders may let the Mortgaged Property or any part thereof and may retain and apply the Rents toward payment of the Term Loan in such order, priority and proportions as the Administrative Agent with the approval of the Required Lenders, in their sole discretion, shall deem proper, or toward the operation, maintenance and repair of the Mortgaged Property, and irrespective of whether the Administrative Agent shall have commenced a foreclosure of this Mortgage or shall have applied or arranged for the appointment of a receiver. The Administrative Agent, on behalf of the Required Lenders, shall give to the Borrower notice of such revocation of the right to let and collect the Rents within a reasonable time thereafter. Except as expressly permitted by this Section 5.12, the Borrower shall not, (i) make, or suffer to be made, any Lease, (ii) modify any Lease, (iii) cancel any Lease, (iv) accept prepayments of installments of the Rents for a period of more than one (1) month in advance, or (v) assign the whole or any part of the Rents other than to the Lenders pursuant to the Transaction Documents. The Borrower shall (i) fulfill or perform each and every provision of the Leases on the part of the Borrower to be fulfilled or performed, (ii) promptly send copies of all notices of default which the Borrower shall send or receive under the Leases to the Administrative Agent and (iii) enforce, short of termination of the Leases, the performance or observance of the provisions thereof by the tenants thereunder. (b) In addition to the rights which the Administrative Agent may have herein, after and during the continuance of any Event of Default, the Administrative Agent, at its option, may require the Borrower to pay monthly in advance to the Administrative Agent, or any receiver appointed to collect the Rents, the fair and reasonable rental value for the use and occupation of such part of the Mortgaged Property as may be in possession of the Borrower. Upon default in any such payment, the Borrower will vacate and surrender possession of the Mortgaged Property to the Administrative Agent, or to such receiver, and, in default thereof, the Borrower may be evicted by summary proceedings or otherwise. Nothing contained in this Section 5.12 or any other provision of this Agreement or any other Transaction Document shall be construed as imposing on the Administrative Agent or any Lender any of the obligations of the lessor under the Leases. (c) The Borrower shall, within thirty (30) days after the date of this Agreement, submit to Administrative Agent for its review and approval and the review and approval of its counsel, a standard form of office lease, which approval shall be given or denied within ten (10) 44 Business Days after receipt of such form and if the Administrative Agent shall fail to respond within such ten (10) Business Day period, then the Administrative Agent shall be deemed to have not approved such proposed form; provided that if thereafter the Borrower shall make the same request, and such second request shall state, in bold type that "the request is a second request and must be responded to by the Administrative Agent within five (5) Business Days or shall be deemed approved," and if the Administrative Agent shall thereafter fail to respond within five (5) Business Days of its receipt of such second request, then such request shall be deemed approved. Without limiting any other provisions of this Section 5.12, all Leases executed after the date hereof, whether or not requiring any consent pursuant to paragraphs (d) and (e) below, shall be on the form of Lease so approved by the Administrative Agent and its counsel without substantive modification except for commercially reasonable modifications typically made in the usual and ordinary course of arm's length negotiations of leases of office space in improvements comparable to the Improvements and, unless otherwise elected by the Administrative Agent, be subject and subordinate to this Agreement and the Transaction Documents and to the Liens thereof, provided that, upon Borrower's request, the Administrative -------- Agent, acting for itself and on behalf of all Lenders shall not unreasonably withhold its agreement to execute and deliver a subordination, non-disturbance and attornment agreement (a "SNDA"), substantially in the Administrative Agent's customary form, a copy of which is attached hereto as Exhibit C, for each Lease entered into subsequent to the date hereof covering the lesser of (i) 10,000 rentable square feet or more or (ii) one full floor or more, of the Improvements. The Borrower shall pay, within thirty (30) days following presentation of invoices therefor, the Administrative Agent's reasonable actual out-of-pocket costs (including, without limitation, reasonable attorneys' fees) incurred in connection with any SNDA. Notwithstanding the previous sentence, the Borrower shall not be liable for such out-of-pocket costs if any such SNDA is presented to the Administrative Agent and is executed in the form of Exhibit C hereto, and when presented to the Administrative Agent, is accompanied by a letter from the Borrower's counsel certifying that such SNDA is in the form of Exhibit C. (d) Provided no Event of Default or material Default has occurred and is continuing, the Borrower shall have the right without the Administrative Agent's or the Required Lenders' prior consent: (A) in the case of any Lease that covers less than 10,000 rentable square feet, to terminate or accept a surrender of any such Lease (1) in accordance with its terms upon a default by the tenant thereunder or (2) in the absence of a default by the tenant thereunder, provided that, if in consideration for such surrender, the tenant -------- makes a commercially reasonable payment to the Borrower, and the Borrower causes such sum to be deposited in an interest bearing escrow account under the control of the Administrative Agent within three (3) Business Days following receipt thereof by the Borrower for subsequent application by the Borrower (upon its written request to the Administrative Agent) to costs or expenses in connection with the reletting of such space, and until so applied shall constitute additional security for the repayment of the Term Loan, or if a new Lease for the same space on surrender or more favorable terms shall be executed on or prior to the date of such termination, (B) to enter into new Leases with tenants which are not Major Leases, provided that each such Lease (1) is substantially in accordance with the form of Lease previously approved by the Administrative Agent and its counsel, except for commercially reasonable modifications typically made in the usual and ordinary course of arm's length negotiations of leases of office space in improvements comparable to the Improvements, and (2) contains commercially reasonable market 45 rate terms; and (C) to modify any such Lease which is not a Major Lease, but only on commercially reasonable market rate terms and provided that after giving effect to such modification, such Lease continues to be substantially (x) in accordance with the standard form of Lease previously approved by the Administrative Agent and its counsel, except for commercially reasonable modifications typically made in the usual and ordinary course of arm's length negotiations of leases of office space in improvements comparable to the Improvements, if such Lease was entered in to after the date of this Agreement or (y) the same as the form of such Lease prior to such amendment, if such Lease exists on the date of this Agreement. For purposes hereof, any consent to a subletting of all or any portion of the premises demised under a Lease, or to an assignment of a Lease, or any recapture, leaseback or similar arrangement of all or any part of the premises demised under a Lease, by Borrower which results directly or indirectly in the release of any tenant from any liability under its Lease shall be deemed a "termination" of a Lease under this Agreement. (e) In each case in this Agreement where a reference to a square footage of a Lease is made, such reference shall be deemed to include the aggregate space of a tenant in the Improvements, whether under one or more Leases, and irrespective of whether the space demised to any such tenant is physically contiguous. Prior to entering into any Lease, or a renewal or amendment or termination of any Lease, in each case respecting a Lease covering 10,000 rentable square feet or more of the Improvements, the Borrower shall deliver to the Administrative Agent the following documents (the "Lease ----- Package"): (A) a final term sheet, in form reasonably satisfactory to the - ------- Administrative Agent, containing all the material terms of the proposed Lease, or such renewal or amendment or termination thereof, as the case may be, including, without limitation, in the case of a new Lease, the identity of the proposed tenant and (B) with respect to a new Lease, such information with respect to the prospective tenant as shall permit the Administrative Agent to assess such proposed tenant's business, character and creditworthiness. The Borrower shall not enter into any Major Lease, or renew, modify, amend or terminate or accept the surrender of any such Major Lease, without first obtaining the prior written consent of the Required Lenders, which consent shall not be unreasonably withheld. With respect to each proposal for a new Major Lease, or for any renewal, amendment or termination of any existing Major Lease, the Administrative Agent shall promptly upon receipt deliver a copy of the Lease Package with respect to such Major Lease or such renewal, amendment or termination, as the case may be, to each Lender. Within ten (10) Business Days after the Lenders shall have received the Lease Package with respect to such Major Lease, the Required Lenders shall either consent or refuse to consent to the Lease Package relating to such Major Lease. If consent to the Lease Package relating to such Major Lease is refused, then the Administrative Agent shall provide to the Borrower the reasons for such refusal. If the Administrative Agent shall fail to respond on behalf of the Required Lenders within such ten (10) Business Day period, then the Required Lenders shall be deemed to have not consented to the proposed Major Lease; provided that if thereafter the Borrower shall make the same request, and such second request shall state, in bold type, that "the request is a second request and must be responded to by the Administrative Agent within five (5) Business Days or shall be deemed approved," then the Administrative Agent shall promptly send such second request to the other Lenders, and if the Administrative Agent shall thereafter fail to respond within five (5) Business Days of its receipt of such second request, then such request shall be deemed approved. If a Lender has not responded to the Administrative Agent with respect to its decision as to a transaction involving a Major Lease prior to the expiration of the 46 such ten (10) Business Day period, then the Administrative Agent shall have the right to respond to such Major Lease transaction on behalf of such Lender. (f) True and complete copies of all Leases in existence on the date hereof (including all modifications, guarantees and other documents related thereto) were delivered to the Administrative Agent prior to the date hereof, and all new Leases and of all modifications, renewal, termination and surrender agreements relating to Leases, together with all guarantees, certificates and other documents delivered in connection therewith, shall be delivered to the Administrative Agent within fifteen (15) Business Days after being fully executed and delivered. (g) Until the Term Loan is fully repaid, operating, reserve, savings, checking, banking and other accounts of the Borrower relating to the Mortgaged Property shall be kept and maintained at, and the Borrower shall cause each property manager to keep and maintain all such accounts relating to the Mortgaged Property in the name of the Borrower at, a branch of the Administrative Agent located in New York, New York. The Borrower shall, or shall cause any Person receiving any Rents, to deposit all Rents received into the operating account for the Mortgaged Property at such branch promptly after receipt. The Borrower shall cause funds to be available in a designated operating account maintained at a branch of the Administrative Agent located in New York sufficient to pay, when due, all interest and amortization payments on the Term Loan; provided that, with respect to interest payments, the -------- Administrative Agent has advised the Borrower of the amount of the interest payment in writing not less than three (3) Business Days prior to its due date, which advice may be made by telecopier. (h) Calculations hereunder of "rentable square footage" of the Improvements shall be calculated on the basis of the entire Improvements containing 1,200,000 rentable square feet of space on the date hereof. ARTICLE VI Negative Covenants ------------------ Until the principal of and interest on the Term Loan and all fees payable hereunder have been paid in full, the Borrower covenants and agrees with the Lenders that: SECTION 6.01. Indebtedness. The Borrower will not create, incur, ------------ assume or permit to exist any indebtedness with respect to the Mortgaged Property, or secured by any interest therein, except for indebtedness created hereunder or commercially reasonable unsecured indebtedness incurred in the ordinary course of business in connection with the operation of the Mortgaged Property and consistent with the applicable Operating Budget. SECTION 6.02. Liens. The Borrower will not create, incur, assume or ----- permit to exist any Lien on the Mortgaged Property, or assign or sell any income or revenues (including accounts receivable) or rights in respect of any thereof, except: 47 (a) the Permitted Encumbrances; (b) the existing Leases and new Leases permitted hereunder; and (c) Liens created by the Transaction Documents; or (d) Liens or attachments which are not affirmatively created or incurred, provided such Liens or attachments are removed of record by bonding or otherwise by the Borrower within thirty (30) days of the Borrower's knowledge thereof and which do not result in a Material Adverse Effect. SECTION 6.03. Fundamental Changes. The Borrower will not merge into ------------------- or consolidate with any other Person, or permit any other Person to merge into or consolidate with it, or sell, transfer, lease or otherwise dispose of (in one transaction or in a series of transactions) all or substantially all of its assets (in each case, whether now owned or hereafter acquired), or liquidate or dissolve, without the prior written consent of the Required Lenders. Notwithstanding the provisions of the preceding sentence, so long as no Default or Event of Default has occurred and is continuing, or would occur after giving effect to the succeeding provisions of this sentence, the merger or consolidation of one or more Persons with and into the Borrower or the Guarantor shall be permitted in connection with the acquisition of Real Estate Assets if the Borrower or the Guarantor, as the case may be, is the surviving entity; provided that prior to any such merger or consolidation (other than (y) the - -------- merger or consolidation of one or more Affiliates with and into the Borrower or (z) the merger of consolidation of two or more of the Affiliates of the Borrower), the Borrower shall provide to the Administrative Agent (with copies to the Administrative Agent for each Lender) a certificate signed by a Financial Officer of the Borrower certifying, to the best knowledge of the signatory, that no Default or Event of Default has occurred and is continuing or would occur and be continuing after giving effect to such merger or consolidation and such merger or consolidation does not have a Material Adverse Effect. SECTION 6.04. Hedging Agreements. The Borrower will offer, or will ------------------ cause its Affiliates to offer, to the Administrative Agent a right of first refusal with respect to any Hedging Agreement the Borrower or any Affiliates of Borrower may enter into in connection with the debt evidenced by the Term Loan Agreement. Such right of first refusal shall operate in the following fashion: If Borrower intends to enter into any Hedging Agreement, the Borrower shall notify the Administrative Agent of Borrower's intention to do so, and shall advise the Administrative Agent of the business terms upon which the Borrower is prepared to enter into such a Hedging Agreement. If the Administrative Agent wishes to exercise its right of first refusal, it shall do so, if at all, by giving the Borrower notice of its desire to enter into a Hedging Agreement on such terms as has been proposed by the Borrower within seven (7) Business Days after the Borrower's notice to the Administrative Agent of its intention to enter into a Hedging Agreement and of such terms. If the Administrative Agent shall give such notice, the same shall constitute an agreement to enter into a Hedging Agreement within seven (7) Business Days thereafter, the form of such Hedging Agreement to incorporate the business terms agreed upon and such other terms as are customarily contained in such types of agreements. If the Administrative Agent shall not so exercise its right of first refusal aforesaid, the Borrower, at any time thereafter, shall be free to enter into a Hedging Agreement in 48 form acceptable to the Borrower with any other Person on business terms not substantially more favorable to such other Person and those offered to the Administrative Agent. If no such transaction with another Person is concluded within sixty (60) days from the expiration of the seven (7) Business Day period in which the Administrative Agent has the right to notify the Borrower that the Administrative Agent wishes to enter into a Hedging Agreement, as aforesaid, then the Borrower, before proceeding to enter into a Hedging Agreement with some other Person, shall be obligated to follow the same right of first refusal procedure. Once having concluded any such transaction, however, there shall be no further right of first refusal available to the Administrative Agent. Nothing herein shall be construed to require any Lender to become a party to a Hedging Agreement. SECTION 6.05. Change in Control; Conduct of Business. At no time -------------------------------------- during the term of this Agreement shall the Guarantor cease to be the sole general partner of the Borrower or shall a Change in Control otherwise occur, without the prior written consent of the Required Lenders, which consent may be withheld in the Required Lenders' sole discretion. The Borrower shall not primarily engage in any business other than the business of owning, purchasing, developing, constructing, renovating and operating office and industrial buildings and hotels in the United States of America and other countries throughout the world. SECTION 6.06. Transfer of the Mortgaged Property. Notwithstanding ---------------------------------- anything to the contrary provided herein, the Borrower shall not sell, assign or otherwise transfer its interest in the Mortgaged Property, in whole or in part, by operation of law or otherwise without the prior written consent of all of the Lenders, which consent may be withheld in their sole discretion. SECTION 6.07. Transactions with Affiliates. The Borrower shall not ---------------------------- engage in any transactions with any of its Affiliates relating to the Mortgaged Property (including without limitation pursuant to a Management Agreement relating to the Mortgaged Property), except on terms and conditions not less favorable than could be obtained on an arms-length basis with unrelated third parties. ARTICLE VII Events of Default ----------------- SECTION 7.01. Events of Default. If any of the following events ----------------- ("Events of Default") shall occur: ----------------- (a) the Borrower shall fail to pay any principal of the Term Loan when and as the same shall become due and payable, whether at the due date thereof or at a date fixed for prepayment thereof or otherwise and such failure shall continue unremedied for five (5) Business Days (such five Business Day grace period shall not apply to payments due on the Maturity Date);

(l) if a Default shall occur under Sections 6.05 or 6.06. (m) any of the Transaction Documents or any material provision of any Transaction Document shall be cancelled, terminated, revoked or rescinded, or any Lien thereof shall cease or lose its priority, otherwise than in accordance with the terms thereof or with the express prior written agreement, consent or approval of the Required Lenders; or any of the Current Guarantees shall be cancelled, terminated, revoked or rescinded at any time or for any reason whatsoever; or any assertion is made by or on behalf of the Borrower or any Affiliate of the Borrower that this Agreement or any other Transaction Document is not legal, valid and binding; or any action at law, suit in equity or other legal proceeding to make unenforceable, or to cancel, revoke or rescind any of the Transaction Documents shall be commenced by or on behalf of the Borrower, the Guarantor or any of its Affiliates, or any court or any Governmental Authority of competent jurisdiction shall make a determination that, or ensure a judgment, order, decree or ruling to the effect that, any one or more the Transaction Documents is illegal, invalid or unenforceable as to any material terms thereof; (n) the Policies are not in full force and effect, or if the Policies are not delivered to the Administrative Agent within five (5) Business Days of request; and 51 (o) an "Event of Default" (as defined in any other Transaction Document) shall occur and be continuing; (p) if a default after any applicable notice and grace shall occur under any mortgage covering all or any part of the Mortgaged Property which is superior or subordinate to the Mortgage (provided, that, nothing in this clause (p) shall be construed to modify the provisions of Section 6.02); then, and in every such event (other than an event described in clause (f) or (g) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent, may and at the request of the Required Lenders, shall, by notice to the Borrower declare the Term Loan then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Term Loan so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower, and the Administrative Agent may, and at the request of the Required Lenders shall, exercise any or all the rights and remedies available under the Transaction Documents at law and in equity, including without limitation, foreclosure of the Mortgaged property; provided, however that the Administrative Agent shall not commence a foreclosure proceeding without the consent of the Required Lenders. In case of any event described in clause (f) or (g) of this Article, however, the principal of the Term Loan then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder and under the other Transaction Documents, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower. ARTICLE VII The Administrative Agent ------------------------ SECTION 8.01. The Administrative Agent. (a) Each of the Lenders ------------------------ hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. (b) The Administrative Agent shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Affiliate thereof as if it were not the Administrative Agent hereunder. (c) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) except for acts of gross negligence or willful misconduct, the Administrative Agent shall not be subject to any fiduciary or other implied duties or liabilities, regardless of whether a Default has occurred and is continuing, 52 however the Administrative Agent shall carry out its obligations hereunder as if it were administering the Term Loan solely for its own account; (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as may be expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Transaction Document, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Transaction Document, (iv) the validity, enforceability, effectiveness or genuineness of any Transaction Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere, other than to confirm receipt of items expressly required hereunder to be delivered to the Administrative Agent. (d) The Administrative Agent shall be entitled to rely upon and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. (e) The Administrative Agent may perform any and all of its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent and approved by the Borrower and the Required Lenders, which approval shall not be unreasonably withheld or delayed. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. (f) Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders 53 and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with and approval by the Borrower, which approval shall not be unreasonably withheld or delayed with respect to the appointment of a Lender as Administrative Agent if such Lender has a Commitment at such time which is either (i) equal to or greater than $20,000,000 or (ii) equal to or greater than the amount of the Commitment held at such time by each other Lender, to appoint a successor Administrative Agent; provided that no approval -------- of the Borrower shall be required if an Event of Default has occurred and is continuing. If, in the case of a resignation by the Administrative Agent, no successor shall have been so appointed by the Required Lenders and, if required, so approved by the Borrower, and no successor Administrative Agent shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York and which would qualify as an Eligible Assignee, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent's resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent. Except as set forth in subparagraph (e) of this Section 8.01, the Administrative Agent agrees that it shall not assign any of its rights or duties as Administrative Agent to any other Person, prior to an Event of Default. (g) Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

The rights and remedies of the Administrative Agent and the Lenders hereunder or under the other Transaction Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or under the other Transaction Documents or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by clause (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

All sums expended by any Lender or the Administrative Agent shall be payable within ten (10) Business Days after demand and, until reimbursed by the Borrower pursuant hereto, shall bear interest at the Default Rate, and such sums with such interest shall be secured by the Transaction Documents. In litigation, or the preparation therefor, the Borrower shall be entitled to select counsel reasonably acceptable to the Required Lenders, and the Administrative Agent (as approved by the Required Lenders) shall be entitled to select their own supervisory counsel. Prior to any settlement of any such litigation by the Lenders, the Lenders shall provide the Borrower and the Guarantor with notice and an opportunity to address any of their concerns with the Lenders, and the Lenders shall not settle any litigation without first obtaining Borrower's consent thereto, which consent shall not be unreasonably withheld or delayed, except that any such settlement relating to clause (iii) of this subparagraph (b) shall be subject to the Borrower's consent which may be withheld by the Borrower in its sole discretion. The obligations of the Borrower under clauses 57 (iii) and (viii) of this paragraph shall, notwithstanding any exculpatory or other provisions of any nature whatsoever set forth in the Transaction Documents, constitute the personal recourse undertakings, obligations and liabilities of the Borrower. (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, as the case may be, such Lender's Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that such indemnity shall not be available to the extent -------- that such losses, claims, damages, liabilities or related expenses resulted from the gross negligence or willful misconduct of the Administrative Agent; provided -------- further that the unreimbursed expense or indemnified loss, claim, damage, - ------- liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such and Borrower hereby indemnifies such Lenders for any such payments made by a Lender to the Administrative Agent. (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transaction, the Term Loan or the use of the proceeds thereof.

SECTION 9.04. Successors and Assigns. (a) The provisions of this ---------------------- Agreement and the other Transaction Documents shall be binding upon and inure to the benefit of the parties hereto and thereto and their respective successors and assigns permitted hereby or thereby, as the case may be, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b) Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement and the other Transaction Documents (including all or a portion of its Commitment and the Term Loan at the time owing to it); provided that (i) the Administrative Agent and -------- the Borrower must each give its prior written consent to such assignment (which consent shall not be unreasonably withheld, delayed or conditioned), irrespective of whether 58 Event of Default has occurred and is continuing, any Lender may assign all or a portion of its rights and obligations under this Agreement and the other Transaction Documents to any Person without the consent of the Borrower and (ii) no such consent shall be required to be obtained from the Administrative Agent or the Borrower in the case of an assignment to a Lender or an Affiliate of a Lender, provided the assigning Lender is not then in default under the terms of this Agreement. Each such assignment shall be subject to the following terms and conditions: (A) Except in the case of an assignment to a Lender or an Affiliate of a Lender, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless the Administrative Agent otherwise consents, in its sole discretion; (B) except in the case of an assignment by a Lender at such time as an Event of Default is continuing, the amount of the remaining Commitment retained by such assigning Lender shall not be less than $10,000,000 unless the Administrative Agent otherwise consents, in its sole discretion; (C) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement; (D) the parties to each assignment shall execute and deliver to the Administrative Agent, for recording in the Register, an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (E) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance and upon payment to the Administrative Agent of the processing and recordation fee of $3,500, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.07, 2.08, 2.09 and 9.03) as well as any fees accrued for its own account not yet paid. Any such Assignment and Acceptance shall run to the benefit of the Borrower, and a copy of such Assignment and Acceptance shall be delivered by the Administrative Agent to the Borrower. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section. Each Lender may make available to each prospective assignee, on a confidential basis, such financial and other information concerning the Borrower and the Transaction as such Lender shall deem necessary. The Administrative Agent agrees to promptly notify all Lenders of any assignment of its rights and obligations as a Lender under this Agreement and further agrees that in the event of an assignment of all such rights and obligations, it shall promptly resign as Administrative Agent. (c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be -------- conclusive, absent manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register 59 shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. IRS Tax Form 4224, or such substitute documentation, required in connection with the Administrative Questionnaire shall be delivered to the Administrative Agent. To the extent required by a Lender, Borrower shall execute and deliver such replacement notes reflecting such assignment. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. (e) Each Lender may sell participations to one or more Eligible Assignees and all or a portion of such Lender's rights and obligations under this Agreement and the other Transaction Documents; provided that (a) each such -------- participation shall be in an amount of not less than $10,000,000, (b) any such sale or participation shall not affect the rights and duties of the selling Lender hereunder with respect to the Borrower, and the Administrative Agent and the selling Lender shall continue to exercise all approvals, disapprovals and other functions of a Lender, (c) the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of, or approvals under, the Transaction Documents shall be the rights to approve waivers, amendments or modifications that would reduce the principal of or the interest rate on the Term Loan, extend the term or increase the amount of the Commitment of such Lender as it relates to such participant, reduce the amount of any fees to which such participant is entitled or extend any regularly scheduled payment date for principal or interest, and (d) no participant shall have the right to grant further participations or assign its rights, obligations or interests under such participations to other Persons without the prior written consent of the Administrative Agent. SECTION 9.05. Survival. All covenants, agreements, representations -------- and warranties made by the Borrower herein and the other Transaction Documents, including without limitation, in certificates and other instruments delivered in connection with or pursuant to this Agreement or any other Transaction Document, shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of the Term Loan, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on the Term Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.07, 2.08, 2.09 and 9.03 and Article VIII shall survive (for a period of one (1) year thereafter) the full repayment of payments due on account of the Term Loan and the termination of the obligations of the Lenders under this Agreement and any of the other Transaction Document. 60 SECTION 9.06. Counterparts; Integration; Effectiveness. This ---------------------------------------- Agreement and the other Transaction Documents may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Transaction Documents, including without limitation, any separate agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement and the other Transaction Documents shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and the Term Loan shall have been funded, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement or any other Transaction Document by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement or any other Transaction Documents. SECTION 9.07. Severability. Any provision of this Agreement or any ------------ other Transaction Documents held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. SECTION 9.08. Right of Setoff. If an Event of Default shall have --------------- occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured; provided the account against which such set- off shall be made shall be one of the operating, savings, checking, escrow, reserve or other accounts relating to the operation of the Mortgaged Property and maintained pursuant to the requirements of Section 5.12(g) of this Agreement. The rights of each Lender under this Section are subject to the provisions of Section 2.10(c) hereof and are in addition to other rights and remedies (including other rights of setoff) which such Lender may have. No other set-offs against accounts of the Borrower or the Guarantor shall be permitted hereunder or under any other Transaction Documents. SECTION 9.09. Governing Law.

                                                              New York, New York
                                                              September 11, 1997


     WHEREAS, BOSTON PROPERTIES LIMITED PARTNERSHIP, a Delaware limited
partnership having an office at c/o Boston Properties, Inc., 8 Arlington Street,
Boston, Massachusetts (the "Borrower"), has applied to THE CHASE MANHATTAN BANK,
                            --------                                            
a New York banking corporation having an office at Chase Real Estate Finance
Group, 380 Madison Avenue, New York, New York ("Chase"), as Administrative Agent
                                                -----                           
for the Lenders (as such term is defined in that certain Term Loan Agreement, of
even date herewith (the "Term Loan Agreement")), for a loan in the principal sum
                         -------------------                                    
of $220,000,000.00 (the "Term Loan"), which Term Loan will be secured, among
                         ---------                                          
other things, by that certain Mortgage, of even date herewith, made by the
Borrower to Chase (the "Mortgage"), covering premises known as 280 Park Avenue,
                        --------                                               
New York, New York, and evidenced by the Note (as such term is defined in the
Mortgage);

     WHEREAS, to induce the Lenders to enter into the Term Loan Agreement, the
undersigned have agreed to execute and deliver this Agreement;

     WHEREAS, the Lenders are willing to extend the Term Loan to the Borrower
only if the Borrower and BOSTON PROPERTIES, INC. ("BPI"), jointly and severally,
                                                   ---                          
execute and deliver this Agreement agreeing and guaranteeing to pay to the
Lenders interest on the Term Loan in the manner hereinafter provided;

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and legal sufficiency of which are hereby
acknowledged, and in order to induce the Lenders to make and extend the Term
Loan to the Borrower, the undersigned hereby acknowledge, agree and confirm that
all of the above recitals are true, correct and complete and hereby covenant and
agree with the Lenders as follows:

     1.   Subject only to the limitation of liability set forth in Paragraph 2
below, until the Term Loan is fully repaid, the undersigned, jointly and
severally, and absolutely, irrevocably and unconditionally, guarantee and agree
to pay to the Lenders, following the occurrence and during the continuance of an
Event of Default including, without limitation, following an acceleration of the
Term Loan pursuant to the Term Loan Agreement, accrued and unpaid interest on
the Term Loan calculated pursuant to the provisions of the Term Loan Agreement
and the Note, whether accruing before or after such an Event of Default,

 
including specifically and without limitation, all interest accruing from and
after the commencement of any case, proceeding or action under any existing or
future laws relating to bankruptcy, insolvency or similar matters with respect
to the Borrower, unaffected by modification thereof in any bankruptcy or
insolvency proceeding, and even though the Lenders may not have an allowed claim
for the same against the Borrower as a result of any bankruptcy or insolvency
proceeding.  For purposes of this Agreement an Event of Default shall be deemed
to be continuing if the same shall be the case under the Term Loan Agreement.

     2.   Notwithstanding anything to the contrary contained in Paragraph 1 of
this Agreement, for purposes of determining the interest liability under this
Agreement, interest shall be deemed to cease to accrue under this Agreement (but
not under the Term Loan Agreement or the Note) from and after the earlier to
occur of the following two (2) dates (the "Cut-Off Date") viz: (a) the date that
the Premises has been sold at a foreclosure sale or a deed-in-lieu of the
foreclosure of the Premises has been accepted by Chase or its nominee, and (b)
the date corresponding to the six (6) month anniversary of an Event of Default
under the Term Loan Agreement, which date shall be extended (i) if and to the
extent that Chase lacked knowledge of such an Event of Default under the Term
Loan Agreement, to the date when Chase first acquired knowledge of the
occurrence of such an Event of Default, or (ii) by the duration of any time
period during which, while such Event of Default remains uncured or is not
waived, the Borrower, BPI, or any related Party of the Borrower or BPI shall at
any time after the occurrence of such Event of Default take any action which
contests or otherwise impedes, delays or interferes with, in any manner, the
exercise of any rights or remedies of Chase under the Term Loan Agreement or any
of the other Transaction Documents, including, without limitation, the
commencement of any case, proceeding or action under any existing or future laws
relating to bankruptcy, insolvency or similar matters which results in a stay of
any enforcement of any right or remedy of the Lenders under any of the
Transaction Documents.  Nothing in this Paragraph 2 shall be construed as
barring the commencement of any such case, proceeding or action by the Borrower
or any Related Party, the effect of such provision merely being that the six (6)
month time limitation on the interest liability of the undersigned shall be
extended until such case, proceeding or action is concluded.  Notwithstanding
the foregoing, if the Borrower or any Related Party shall successfully contest
any such Event of Default, or if such Event of Default is cured, revoked,
rescinded or waived, then, in such circumstance, the provisions set forth in
clause (b) of this Paragraph 2 will once again become applicable upon the
occurrence and during the continuance of any subsequent Event of Default under
the Term Loan Agreement.

     3.   The undersigned agree to pay to Chase and the other Lenders the
reasonable cost of any and all lawful action that may be taken by Chase and the
other Lenders in connection with the enforcement of the provisions of this
Agreement, whether or not suit is filed in connection therewith, or in
connection with either or both of the undersigned becoming a party to a
voluntary or involuntary federal or state bankruptcy, insolvency or similar
proceeding (including, but not limited to, reasonable attorneys' fees and

                                      -2-

 
disbursements, whether in house staff, retained firms or otherwise).  All sums
due Chase and the other Lenders under this paragraph 3 by the undersigned shall
be payable by the undersigned from time to time within ten (10) Business Days of
demand and, until paid in full, shall bear interest from such due date at the
Default Rate.  The obligations of the undersigned pursuant to paragraphs 1 and 3
hereof are hereinafter collectively referred to as the "Liabilities".
                                                        -----------  

     4.   The undersigned hereby expressly agrees that this Agreement is
independent of, and in addition to, all collateral, if any, granted, pledged or
assigned under the Transaction Documents.

     5.   BPI hereby consents that from time to time, before or after any
Default, with or without further notice to or assent from BPI:

          (a) any security at any time held by or available to Chase or the
other Lenders for any obligation of the Borrower, or any security at any time
held by or available to Chase or the other Lenders for any obligation of any
other person or party primarily, secondarily or otherwise liable for all or any
portion of the Term Loan and/or any other obligations of the Borrower or any
other person or party (other than Chase and the Lenders) under any of the
Transaction Documents ("Other Obligations"), if any, including any guarantor of
                        -----------------                                      
the Term Loan and/or of any of such Other Obligations, may be accelerated,
settled, exchanged, surrendered or released and Chase and the other Lenders may
fail to set off and may release, in whole or in part, any balance of any deposit
account or credit on its books in favor of the Borrower, or of any such other
person or party;

          (b) any obligation of the Borrower, or of any such other person or
party, may be changed, altered, renewed, extended, continued, accelerated,
surrendered, compromised, settled, waived or released in whole or in part, or
any Default or Event of Default thereto waived; and

          (c) Chase or any other Lender may extend further credit in any manner
whatsoever to the Borrower, and generally deal with the Borrower or any of the
above mentioned security, deposit account, credit on its books or other person
or party as Chase or any other Lender may see fit;

and BPI shall remain bound in all respects for the Liabilities under this
Agreement, without any loss of any rights by Chase or the other Lenders and
without affecting the liability of the undersigned, notwithstanding any such
exchange, surrender, release, change, alteration, renewal, extension,
continuance, compromise, waiver, inaction, extension of further credit or other
dealing; and the Borrower agrees that none of the events described in clauses
(a)-(c) above shall be construed in any way to result in a release of the
Borrower from its personal recourse obligations hereunder for the Liabilities.

                                      -3-

 
     6.   All moneys available to Chase or the other Lenders pursuant to the
Transaction Documents for application in payment or reduction of the Term Loan,
the Liabilities and/or any Other Obligations may be applied by Chase in such
manner and in such amounts and at such time or times and in such order, priority
and proportions as Chase may see fit.

     7.   The undersigned hereby waives:

          (a) notice of acceptance of this Agreement and of the extending of the
Term Loan or the making of any advance thereunder by the Lenders to the
Borrower;

          (b) presentment and demand for payment of the Liabilities or any
portion thereof;

          (c) protest and notice of dishonor or default to any of the
undersigned or to any other person or party with respect to the Liabilities or
any portion thereof;

          (d) all other notices to which any of the undersigned might otherwise
be entitled; and

          (e) any demand under this Agreement.

     8.   If any of the following events should occur:

          (a) an Event of Default continues uncured;

          (b) any of the undersigned violates any provision of this Agreement;

          (c) any of the undersigned terminates or dissolves or suspends its
usual business activities or conveys, sells, leases, transfers or otherwise
disposes of all or substantially all of its property, business or assets other
than in the ordinary course of business;

then, and in such event, Chase may declare the Liabilities to be, and the same
shall become, immediately due and payable.

     9.   This Agreement includes a personal recourse agreement by the Borrower
and a personal recourse guaranty by BPI.  BPI acknowledges and agrees that such
guaranty is a guaranty of payment and not of collection.  The undersigned waive
any right to require that any action be brought against the Borrower or any
other person or party or to require that resort be had to any security or to any
balance of any deposit account or credit on the books of Chase or any other
Lender in favor of the Borrower or any other person or party.  Any payment on
account of or reacknowledgment of the Liabilities by the Borrower or any other

                                      -4-

 
party liable therefor shall be deemed to be made on behalf of BPI and shall
serve to start anew the statutory period of limitations applicable to the
Liabilities.

     10.  The provisions hereof shall inure to the benefit of Chase and the
other Lenders, and shall be binding upon each of the undersigned.  Each
reference herein to Chase and the other Lenders shall be deemed to include their
respective successors and assigns permitted pursuant to the provisions of the
Term Loan Agreement, and each reference to Chase shall refer to it in its
capacity as a Lender and as the Administrative Agent under the Transaction
Documents.  Each reference herein to the undersigned shall be deemed to include
the administrators, legal representatives, successors and assigns of the
undersigned, provided, however, that the undersigned shall in no event nor under
any circumstance have the right, without obtaining the prior written consent of
Chase, to assign or transfer the Liabilities, in whole or in part, to any other
person, party or entity.

     11.  The term "undersigned" as used herein shall, if this Agreement is
                    -----------                                            
signed by more than one party, unless otherwise stated herein, mean the
"undersigned and each of them'' and each undertaking herein contained shall be
their joint and several undertaking. Chase may proceed against none, one or more
of the undersigned at one time or from time to time as it sees fit in its sole
and absolute discretion.  If any party hereto shall be a partnership, the
agreements and obligations on the part of the undersigned herein contained shall
remain in force and application notwithstanding any changes in the individuals
composing the partnership and the term "undersigned" shall include any altered
or successive partnerships, but the predecessor partnerships and their general
partner(s) shall not thereby be released from any obligations or liability
hereunder.  If any party hereto shall be a corporation, the agreements and
obligations on the part of the undersigned herein contained shall remain in
force and application notwithstanding the merger, consolidation, reorganization
or absorption thereof, and the term "undersigned" shall include such new entity,
but the old entity shall not thereby be released from any obligations or
liabilities hereunder.

     12.  No delay on the part of Chase or any other Lender in exercising any
right or remedy under this Agreement or failure to exercise the same shall
operate as a waiver in whole or in part of any such right or remedy.  No notice
to or demand on any of the undersigned shall be deemed to be a waiver of the
obligations of any of the undersigned or of the right of Chase or any other
Lender to take further action without notice or demand as provided in this
Agreement.  No course of dealing between any of the undersigned and Chase or any
other Lender shall change, modify or discharge, in whole or in part, this
Agreement or any obligations of the undersigned hereunder.

     13.  This Agreement may only be modified, amended, changed or terminated by
an agreement in writing signed by Chase, as Administrative Agent, and both of
the undersigned. No waiver of any term, covenant or provision of this Agreement
shall be effective unless given in writing by Chase, as Administrative Agent,
and if so given by Chase shall only be 

                                      -5-

 
effective in the specific instance in which given. The execution and delivery
hereafter to Chase or any other Lender by any of the undersigned of a new
instrument of guaranty or any reaffirmation of guaranty, of whatever nature,
shall not terminate, supersede or cancel this instrument, unless executed by
Chase, as Administrative Agent, and expressly so provided therein, and all
rights and remedies of Chase and the other Lenders hereunder and under each
other Transaction Document, at law and in equity, whether against any or both of
the undersigned or any other party or parties, shall be cumulative and may be
exercised singly or concurrently.

     14.  The undersigned acknowledge that this Agreement and the undersigned's
obligations under this Agreement are and shall at all times continue to be
absolute, irrevocable and unconditional in all respects, and shall at all times
be valid and enforceable irrespective of any other agreements or circumstances
of any nature whatsoever which might otherwise constitute a defense to this
Agreement and the obligations of any of the undersigned under this Agreement or
the obligations of any other person or party relating to this Agreement or the
obligations of any of the undersigned hereunder or otherwise with respect to the
Term Loan, or the Liabilities, including, but not limited to, the realization
upon any collateral given, pledged or assigned as security for all or any
portion of the Term Loan, or the filing of a petition under Title 11 of the
United States Code with regard to the undersigned, or the commencement of an
action or proceeding for the benefit of the creditors of the undersigned, or the
obtaining by Chase of title to any collateral given, pledged or assigned as
security for the Term Loan by reason of foreclosure or enforcement of Chase's
lien thereon, the acceptance of an assignment or deed in lieu of foreclosure or
sale, or otherwise.  This Agreement sets forth the entire agreement and
understanding of Chase, the other Lenders and the undersigned with respect to
the matters covered by this Agreement and the undersigned acknowledge that no
oral or other agreements, understandings, representations or warranties exist
with respect to this Agreement or with respect to the Liabilities, except those
specifically set forth in this Agreement.

     15.  This Agreement has been validly authorized, executed and delivered by
each of the undersigned.  The undersigned represent and warrant to Chase and the
other Lenders that they have the corporate and partnership power to do so and to
perform their respective obligations under this Agreement, and this Agreement
constitutes the legally binding obligations of each of the undersigned fully
enforceable against each of the undersigned in accordance with the terms hereof.
The undersigned further represent and warrant to Chase and the other Lenders
that:

          (a) neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby nor compliance with the
terms and provisions hereof will violate any applicable provision of law or any
applicable regulation or other manifestation of governmental action; and

                                      -6-

 
          (b) all necessary approvals, consents, licenses, registrations and
validations of any governmental regulatory body, including, without limitation,
approvals required to permit the undersigned to execute and carry out the
provisions of this Agreement, for the validity of the obligations of the
undersigned hereunder and for the making of any payment or remittance of any
funds required to be made by either of the undersigned under this Agreement,
have been obtained and are in full force and effect.

     16.  Notwithstanding any payments made by BPI pursuant to the provisions of
this Agreement, BPI shall not seek to enforce or collect upon any rights which
it now has or may acquire against the Borrower either by way of subrogation,
indemnity, reimbursement or contribution for any amount paid under this
Agreement or by way of any other obligations whatsoever of the Borrower to BPI,
nor shall BPI file, assert or receive payment on any claim, whether now existing
or hereafter arising, against the Borrower in the event of the commencement of a
case by or against the Borrower under Title 11 of the United States Code.  In
the event either a petition is filed under said Title 11 of the United States
Code with regard to the Borrower or an action or proceeding is commenced for the
benefit of the creditors of the Borrower, this Agreement shall at all times
thereafter remain effective in regard to any payments or other transfers of
assets to Chase or any other Lender, received from or on behalf of the Borrower
prior to notice of termination of this Agreement and which are or may be held
voidable on the grounds of preference or fraud, whether or not the Term Loan has
been paid in full.

     17.  Any notice, request or demand given or made under this Agreement shall
be in writing and shall be hand delivered or sent by Federal Express or other
reputable courier service or by postage prepaid registered or certified mail,
return receipt requested, and shall be deemed given (a) when received at the
following addresses if hand delivered or if sent by Federal Express or other
reputable courier service, and (b) three (3) Business Days after being

     18.  This Agreement is, and shall be deemed to be, a contract entered into
under and pursuant to the laws of the State of New York and shall be in all
respects governed, construed, applied and enforced in accordance with the laws
of the State of New York without regard to principles of conflicts of laws.  The
undersigned acknowledges and agrees that this Agreement is, and is intended to
be, an instrument for the payment of money only, as such phrase is used in (S)
3213 of the Civil Practice Law and Rules of the State of New York, and the

Lenders' rights and remedies pursuant to said (S) 3213.

     19.  Each of the undersigned agrees to submit to personal jurisdiction in

In furtherance of such agreement, the undersigned hereby agree and consent that
without limiting other methods of obtaining jurisdiction, personal jurisdiction

waives any and all right to assert or interpose any defense (other than the
right of the undersigned to assert or interpose the defense that the Cut-off
Date has occurred and its Liabilities under this Agreement have terminated
pursuant to the terms of this Agreement), setoff, counterclaim or crossclaim of
any nature whatsoever with respect to this Agreement, the Liabilities, or the
obligations of any other person or party relating to this Agreement or otherwise
with respect to the Term Loan in any action or proceeding brought by Chase or

Agreement (provided, however, that the foregoing shall not be deemed a waiver of
the right of the undersigned to assert any compulsory counterclaim maintained in
a court of the United States, or of the State of New York if such counterclaim
is compelled under local law or rule of procedure, nor shall the foregoing be
deemed a waiver of the right of the undersigned to assert any claim which would
constitute a defense, setoff, counterclaim or crossclaim of any nature
whatsoever against Chase in any separate action or proceeding).

     21.  No exculpatory provisions which may be contained in the Note, the
Mortgage, the Term Loan Agreement or in any other Transaction Document shall in

under the Other Agreements (as hereinafter defined).  The discharge of any or
all of the undersigned's obligations and liabilities under any one or more of
the Other Agreements by the undersigned or by reason of operation of law or
otherwise shall in no event or under any circumstance constitute or be deemed to
constitute a discharge, in whole or in part, of the undersigned's obligations
and liabilities under this Agreement.  Conversely, the discharge of any or all
of the undersigned's obligations and liabilities under this Agreement by the
undersigned or by reason of operation of law or otherwise shall in no event or
under any circumstance constitute or be deemed to constitute a discharge, in
whole or in part, of the undersigned's obligations and liabilities under any of
the Other Agreements.  The term "Other Agreements" as used herein shall mean (a)
                                 ----------------

connection with the Term Loan.  The undersigned hereby undertakes and agrees
that this Agreement shall remain in full force and effect for all of the
liabilities of the undersigned hereunder, notwithstanding the maturity of the
Term Loan, whether by acceleration, scheduled maturity or otherwise, subject
however, to the provisions of Paragraph 2 hereof.

     23.  This Agreement may be executed in one or more counterparts by some or
all of the parties hereto, each of which counterparts shall be an original and

hereof, shall not relieve the other signatory or signatories from their
obligations hereunder.

     24.  Capitalized terms not defined in this Agreement shall have the
meanings ascribed to such terms in the Term Loan Agreement.

     25.  THE UNDERSIGNED HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, AND
CHASE BY ITS ACCEPTANCE OF THIS AGREEMENT IRREVOCABLY AND UNCONDITIONALLY
WAIVES, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR COUNTERCLAIM
ARISING IN CONNECTION WITH, OUT OF OR OTHERWISE RELATING TO THIS AGREEMENT.

     WHEREAS, to induce the Lenders to enter into the Term Loan Agreement, the

     WHEREAS, the Lenders are willing to extend the Term Loan to the Borrower
only if the Borrower and BOSTON PROPERTIES, INC. ("BPI"), jointly and severally,
                                                   ---

     NOW, THEREFORE, in consideration of the premises and other good and

Loan to the Borrower, the undersigned hereby acknowledge, agree and confirm that
all of the above recitals are true, correct and complete and hereby covenant and
agree with the Lenders as follows:

     1.   Subject only to the limitation of liability set forth in Paragraph 2
below, until the Term Loan is fully repaid, the undersigned, jointly and
severally, and absolutely, irrevocably and unconditionally, guarantee and agree
to pay to the Lenders, following the occurrence and during the continuance of an
Event of Default, including without limitation following an acceleration of the

Shortfall from time to time, whether accruing before or after the occurrence of
any such Event of Default.  From and after the occurrence of an Event of

                                     - 1 -

 
Default, the amount of any Net Cash Flow Shortfall as at the first day of each
calendar month, shall be paid to Chase on the first day of each calendar month
succeeding such Event of Default.  For the purposes of this Agreement an Event
of Default shall be deemed to be continuing if the same shall be the case under
the Term Loan Agreement.

          The term "Net Cash Flow Shortfall" as used in this Agreement shall
                    -----------------------                                 
mean with respect to any period of time, the amount, if any, by which capital
expenditures, including without limitation, tenant improvements and other
alterations, leasing commissions, and reasonable reserves for such items and
other capital expenditures, paid or incurred (or imputedly incurred in the case
of reasonable reserves) during the period in question exceeds the Net Operating
                                                      -------                  
Income for such period.  The term "Net Operating Income" as used in this
                                   --------------------                 
Agreement means Property Income less Property Expenses.  The term "Property
                                ----                               --------
Income" as used in this Agreement means the sum, determined on a cash basis, as
- ------                                                                         
and when received, of all gross income and Rentals paid to the owner of the
Premises from the ownership and operation of such Premises, service fees and
charges, rebates, refunds, all tenant expense reimbursement income and all
insurance and condemnation proceeds net of costs permitted under the Mortgage
and not included in Property Expenses but excluding (i) any proceeds resulting
from a transfer and (ii) security deposits received by tenants until forfeited.
The term "Rentals" as used in this Agreement means, collectively, all payments
          -------                                                             
made by tenants under their lease obligations and all other persons or entities
(corporate partnerships or otherwise) making payments to the Borrower for the
use and occupation of the Premises, whether constituting rents, royalties,
issues, profits, condemnation and insurance proceeds (except as otherwise
provided in the Mortgage), refunds, rebates, escalations, option payments,
application of security deposits, collection proceeds and other payments of
whatever type or nature, foreseen or unforeseen, whether in payment of past,
present or future obligations.  The term "Property Expenses" as used in this
                                          -----------------                 
Agreement means the following items with respect to the Premises, determined in
accordance with GAAP, without duplication thereof (provided, however, that
Property Expenses shall not include tenant improvements, tenant work allowances
and tenant expenses (to the extent actually incurred) debt service (principal
and interest), non-cash items such as depreciation and amortization and any
extraordinary expenditures not considered operating expenses in accordance with
GAAP); (i) all expenses for the operation of the Premises incurred by the
Borrower, but not including any expenses incurred in connection with a sale of
other capital or interim capital transaction; (ii) taxes, water charges,
property taxes, sewer rents, other than fines, penalties, interest or such taxes
(or portions thereof) that are payable by reason of the failure of the owner of
the property to pay a tax timely; (iii) the cost of routine maintenance (the
cost of which may be expenses), repairs and minor alterations, the cost of which
can be expensed under GAAP; (iv) all reasonable and customary expenses incurred
by the Borrower directly relating to the ownership of the Premises, such as
asset and property management fees and insurance expenses and also including
accounting costs and legal fees (but excluding other costs not directly related
to the ownership of the Premises), provided that if the Borrower owns properties
other than the 

                                     - 2 -

 
Premises any such expense not directly related to the ownership of the Premises
but permitted as a Property Expense under this paragraph (iv) shall be included
only to the extent equitably allocable to the Premises; and (v) all commercially
reasonable expenses incurred by the Borrower in connection with the takeover of
any leases in connection with leases entered into in accordance with the terms
hereof.

     2.   Notwithstanding anything to the contrary contained in Paragraph 1 of
this Agreement, liability under this Agreement for Net Cash Flow Shortfall shall
not apply after a Debt Service Coverage Ratio of 1.2 to 1.0 is achieved for two
(2) consecutive calendar quarters; provided, however, that if subsequent to such
                                   --------  -------                            
achievement of a 1.2 to 1.0 Debt Service Coverage Ratio, the Term Loan Debt
Service Coverage Ratio shall become less than 1.2 to 1.0 for any one (1)
calendar quarter, then the undersigned shall again have liability hereunder for
the Net Cash Flow Shortfall.

     3.   The undersigned agree to pay to Chase and the other Lenders the
reasonable cost of any and all lawful action that may be taken by Chase and the
other Lenders in connection with the enforcement of the provisions of this
Agreement, whether or not suit is filed in connection therewith, or in
connection with either or both of the undersigned, becoming a party to a
voluntary or involuntary federal or state bankruptcy, insolvency or similar
proceeding, (including, but not limited to, reasonable attorneys' fees and
disbursements, whether in-house staff, retained firms or otherwise).  All sums
due Chase and the other Lenders under this paragraph 3 by the undersigned shall
be payable by the undersigned from time to time within ten (10) Business Days of
demand and, until paid in full, shall bear interest from such due date at the
Default Rate.  The obligations of the undersigned pursuant to paragraphs 1 and 3
hereof are hereinafter collectively referred to as the "Liabilities".
                                                        ------------ 

     4.   The undersigned hereby expressly agrees that this Agreement is
independent of, and in addition to, all collateral, if any, granted, pledged or
assigned under the Transaction Documents.

     5.   BPI hereby consents that from time to time, before or after any
default by the Borrower, with or without further notice to or assent from BPI:

          (a) any security at any time held by or available to Chase or the
other Lenders for any obligation of the Borrower, or any security at any time
held by or available to Chase or the other Lenders for any obligation of any
other person or party primarily, secondarily or otherwise liable for all or any
portion of the Term Loan and/or any other obligations of the Borrower or any
other person or party (other than Chase and the Lenders) under any of the
Transaction Documents ("Other Obligations"), if any, including any guarantor of
                        -----------------                                      
the Term Loan and/or of any of such Other Obligations, may be accelerated,
settled, exchanged, surrendered or released and Chase and the other Lenders may
fail to set 

                                     - 3 -

 
off and may release, in whole or in part, any balance of any deposit account or
credit on its books in favor of the Borrower, or of any such other person or
party;

          (b) any obligation of the Borrower, or of any such other person or
party, may be changed, altered, renewed, extended, continued, accelerated,
surrendered, compromised, settled, waived or released in whole or in part, or
any Default or Event of Default thereto waived; and

          (c) Chase or any other Lender may extend further credit in any manner
whatsoever to the Borrower, and generally deal with the Borrower or any of the
above mentioned security, deposit account, credit on its books or other person
or party as Chase or any other Lender may see fit;

and BPI shall remain bound in all respects under this Agreement, without any
loss of any rights by Chase or the other Lenders and without affecting the
liability of the undersigned, notwithstanding any such exchange, surrender,
release, change, alteration, renewal, extension, continuance, compromise,
waiver, inaction, extension of further credit or other dealing; and the Borrower
agrees that none of the events described in clauses (a)-(c) above shall be
construed in any way to result in a release of the Borrower from its personal
recourse obligation hereunder for the Liabilities.

     6.   All moneys available to Chase or the other Lenders pursuant to the
Transaction Documents for application in payment or reduction of the Term Loan,
the Liabilities and/or any Other Obligations may be applied by Chase in such
manner and in such amounts and at such time or times and in such order, priority
and proportions as Chase may see fit.

     7.   The undersigned hereby waives:

          (a) notice of acceptance of this Agreement and of the extending of the
Term Loan or the making of any advance thereunder by the Lenders to the
Borrower;

          (b) presentment and demand for payment of the Liabilities or any
portion thereof;

          (c) protest and notice of dishonor or default to any of the
undersigned or to any other person or party with respect to the Liabilities or
any portion thereof;

          (d) all other notices to which any of the undersigned might otherwise
be entitled; and

          (e) any demand under this Agreement.

                                     - 4 -

 
     8.   If any of the following events should occur:

          (a) an Event of Default continues uncured;

          (b) any of the undersigned violates any provision of this Agreement;

          (c) any of the undersigned terminates or dissolves or suspends its
usual business activities or conveys, sells, leases, transfers or otherwise
disposes of all or substantially all of its property, business or assets other
than in the ordinary course of business;

then, and in such event, Chase may declare the Liabilities to be, and the same
shall become, immediately due and payable.

     9.   This Agreement includes a personal recourse agreement by the Borrower
and a personal recourse guaranty by BPI.  BPI acknowledges and agrees that such
guaranty is a guaranty of payment and not of collection.  The undersigned waive
any right to require that any action be brought against the Borrower or any
other person or party or to require that resort be had to any security or to any
balance of any deposit account or credit on the books of Chase or any other
Lender in favor of the Borrower or any other person or party.  Any payment on
account of or reacknowledgment of the Liabilities by the Borrower or any other
party liable therefor shall be deemed to be made on behalf of BPI and shall
serve to start anew the statutory period of limitations applicable to the
Liabilities.

     10.  The provisions hereof shall inure to the benefit of Chase and the
other Lenders, and shall be binding upon each of the undersigned.  Each
reference herein to Chase and the other Lenders shall be deemed to include their
respective successors and assigns permitted pursuant to the provisions of the
Term Loan Agreement, and each reference to Chase shall refer to it in its
capacity as a Lender and as the Administrative Agent under the Transaction
Documents.  Each reference herein to the undersigned shall be deemed to include
the administrators, legal representatives, successors and assigns of the
undersigned, provided, however, that the undersigned shall in no event nor under
any circumstance have the right, without obtaining the prior written consent of
Chase, to assign or transfer the Liabilities, in whole or in part, to any other
person, party or entity.

     11.  The term "undersigned" as used herein shall, if this Agreement is
                    -----------                                            
signed by more than one party, unless otherwise stated herein, mean the
"undersigned and each of them" and each undertaking herein contained shall be
their joint and several undertaking. Chase may proceed against none, one or more
of the undersigned at one time or from time to time as it sees fit in its sole
and absolute discretion.  If any party hereto shall be a partnership, the
agreements and obligations on the part of the undersigned herein contained shall
remain in force and application notwithstanding any changes in the individuals
composing the partnership and the term "undersigned" shall include any altered
or successive 

                                     - 5 -

 
partnerships, but the predecessor partnerships and their general partner(s)
shall not thereby be released from any obligations or liability hereunder. If
any party hereto shall be a corporation, the agreements and obligations on the
part of the undersigned herein contained shall remain in force and application
notwithstanding the merger, consolidation, reorganization or absorption thereof,
and the term "undersigned" shall include such new entity, but the old entity
shall not thereby be released from any obligations or liabilities hereunder.

     12.  No delay on the part of Chase or any other Lender in exercising any
right or remedy under this Agreement or failure to exercise the same shall
operate as a waiver in whole or in part of any such right or remedy.  No notice
to or demand on any of the undersigned shall be deemed to be a waiver of the
obligations of any of the undersigned or of the right of Chase or any other
Lender to take further action without notice or demand as provided in this
Agreement.  No course of dealing between any of the undersigned and Chase or any
other Lender shall change, modify or discharge, in whole or in part, this
Agreement or any obligations of the undersigned hereunder.

     13.  This Agreement may only be modified, amended, changed or terminated by
an agreement in writing signed by Chase, as Administrative Agent, and both of
the undersigned. No waiver of any term, covenant or provision of this Agreement
shall be effective unless given in writing by Chase, as Administrative Agent,
and if so given by Chase shall only be effective in the specific instance in
which given.  The execution and delivery hereafter to Chase or any other Lender
by any of the undersigned of a new instrument of guaranty or any reaffirmation
of guaranty, of whatever nature, shall not terminate, supersede or cancel this
instrument, unless executed by Chase, as Administrative Agent, and expressly so
provided therein, and all rights and remedies of Chase and the other Lenders
hereunder and under each other Transaction Document, at law and in equity,
whether against any or both of the undersigned or any other party or parties,
shall be cumulative and may be exercised singly or concurrently.

     14.  The undersigned acknowledge that this Agreement and the undersigneds'
obligations under this Agreement are and shall at all times continue to be
absolute, irrevocable and unconditional in all respects, and shall at all times
be valid and enforceable irrespective of any other agreements or circumstances
of any nature whatsoever which might otherwise constitute a defense to this
Agreement and the obligations of any of the undersigned under this Agreement or
the obligations of any other person or party relating to this Agreement or the
obligations of any of the undersigned hereunder or otherwise with respect to the
Term Loan, the Term Loan, the other obligations or the Liabilities, including,
but not limited to, the realization upon any collateral given, pledged or
assigned as security for all or any portion of the Term Loan, or the filing of a
petition under Title 11 of the United States Code with regard to the
undersigned, or the commencement of an action or proceeding for the benefit of
the creditors of the undersigned, or the obtaining by Chase of title to any
collateral given, pledged or assigned as security for the Term Loan by reason of

                                     - 6 -

 
foreclosure or enforcement of Chase's lien thereon, the acceptance of an
assignment or deed in lieu of foreclosure or sale, or otherwise.  This Agreement
sets forth the entire agreement and understanding of Chase, the other Lenders
and the undersigned with respect to the matters covered by this Agreement and
the undersigned acknowledge that no oral or other agreements, understandings,
representations or warranties exist with respect to this Agreement or with
respect to the Liabilities, except those specifically set forth in this
Agreement.

     15.  This Agreement has been validly authorized, executed and delivered by
each of the undersigned.  The undersigned represent and warrant to Chase and the
other Lenders that they have the corporate and partnership power to do so and to
perform their respective obligations under this Agreement, and this Agreement
constitutes the legally binding obligations of each of the undersigned fully
enforceable against each of the undersigned in accordance with the terms hereof.
The undersigned further represent and warrant to Chase and the other Lenders
that:

          (a) neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby nor compliance with the
terms and provisions hereof will violate any applicable provision of law or any
applicable regulation or other manifestation of governmental action; and

          (b) all necessary approvals, consents, licenses, registrations and
validations of any governmental regulatory body, including, without limitation,

          (b) All obligations and liabilities of the undersigned under this

commenced prior to, or which otherwise relates back to the period before, the
Cut-Off Date; provided further that if there shall be a foreclosure of the
Mortgage, and title to the Mortgaged Property shall be transferred to the
Lenders or their designee, then the Cut-Off Date shall be twenty-four (24)
months from the later to occur of (x) the date title is so transferred and (y)
the date of such audit.  In addition, if prior to the Cut-Off Date, the Term
Loan was paid in full the Mortgaged Property is sold (other than pursuant to a
foreclosure of the Mortgage), and any Lender shall become a mortgagee of the
Mortgaged Property, then with respect to such Lender or Lenders, the Cut-Off
Date shall be the date such Lender or Lenders becomes a mortgagee of the
Mortgaged Property pursuant to a mortgage other than the Mortgage.

          (c) Notwithstanding the provisions of subparagraph (b) of this Section
7, in no event shall the provisions of subparagraph (b) release or terminate the
