Not later than 1:00 p.m., Cleveland time, on the date specified for any Loan (which must be a Banking Day), each Lender shall make its Percentage of the Loan in immediately available funds available to the Administrative Agent at the Administrative Agent’s Office. Upon satisfaction or waiver of the applicable conditions set forth in Articles 6, 7 and 10, such Loan shall be wire transferred on that date in immediately available funds to the account or accounts designated in the wiring instructions included in such Request for Loan. Following each such Loan disbursement, the Administrative Agent will make available for review by the Lenders the Borrower’s Request for Loan, together with any inspections completed by Lender’s Consultant, the date down endorsement, the Borrower’s Certificate, the completed Soft and Hard Cost Requisition Form, and the pay applications (prepared using AIA Form G702 and G703) certified by Borrower.

If the Administrative Agent has made funds available to Borrower based on such assumption and such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender plus an administrative fee of $200. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent promptly shall notify Borrower and Borrower shall pay such corresponding amount (but not the administrative fee) to the Administrative Agent. The Administrative Agent also shall be entitled to recover from such Lender or Borrower interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) from such Lender, the daily Federal Funds

Effective Rate or (ii) from Borrower, at the applicable rate for such Loan.

circumstances, to the extent reasonably allocable to such obligations under this Agreement, provided that Borrower shall not be obligated to pay any such amount which arose prior to the date which is ninety (90) days preceding the date of such demand or is attributable to periods prior to the date which is ninety (90) days preceding the date of such demand. Each Lender’s determination of such amounts shall be conclusive in the absence of manifest error.

     3.5 LIBOR Costs and Related Matters.

          (a) If, after the date hereof, the existence or occurrence of any Special LIBOR Circumstance:

               (i) shall subject any Lender or its LIBOR Lending Office to any tax, duty or other charge or cost with respect to any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances, or shall change the basis of taxation of payments to any Lender attributable to the principal of or interest on any LIBOR Rate Advance or any other amounts due under this Agreement in respect of any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Advances or its obligation to make LIBOR Rate Advances, excluding (i) taxes imposed on or measured in whole or in part by its overall net income (including taxes on gross income imposed in lieu of net income, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which it is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which it is “doing business” and (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which it has failed, for any reason, to provide Borrower with the appropriate form or forms required by Section 18.21, to the extent such forms are then required by applicable Laws to establish a complete exemption;

               (ii) shall impose, modify or deem applicable any reserve not applicable or deemed applicable on the date hereof (including any reserve imposed by the Board of Governors of the Federal Reserve System, special deposit, capital or similar requirements against assets of, deposits with or for the account of, or credit extended by, any Lender or its LIBOR Lending Office); or

               (iii) shall impose on any Lender or its LIBOR Lending Office or the London interbank market any other condition affecting any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Advances, its obligation to make LIBOR Rate Advances or this Agreement, or shall otherwise affect any of the same;

and the result of any of the foregoing, as determined in good faith by such Lender, increases the cost to such Lender or its LIBOR Lending Office of making or maintaining any LIBOR Rate Advance or in respect of any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances or reduces the amount of any sum received or receivable by such Lender or its LIBOR Lending Office with respect to any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Advances or its obligation to make LIBOR Rate Advances, then, within five (5) Banking Days after demand by such Lender (with a copy to the Administrative Agent), Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction (determined as though such

Lender’s LIBOR Lending Office had funded 100% of its LIBOR Rate Advance in the London interbank market), provided, that with respect to any additional amount arising as a result of the occurrence of an event described in clause (i) above, Borrower shall not be obligated to pay any such amount which arose prior to the date which is ninety (90) days preceding the date of such demand or is attributable to periods prior to the date which is ninety (90) days preceding the date of such demand. A statement of any Lender claiming compensation under this subsection shall be conclusive in the absence of manifest error.

          (b) If, after the date hereof, the existence or occurrence of any Special LIBOR Circumstance shall, in the good faith opinion of any Lender, make it unlawful or impossible for such Lender or its LIBOR Lending Office to make, maintain or fund its portion of any LIBOR Rate Loan, or materially restrict the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, or to determine or charge interest rates based upon the LIBOR Rate, and such Lender shall so notify the Administrative Agent, then such Lender’s obligation to make LIBOR Rate Advances shall be suspended for the duration of such illegality or impossibility and the Administrative Agent forthwith shall give notice thereof to the other Lenders and Borrower. Upon receipt of such notice, the outstanding principal amount of such Lender’s LIBOR Rate Advances, together with accrued interest thereon, automatically shall be converted to Alternate Base Rate Advances on either (1) the last day of the LIBOR Period(s) applicable to such LIBOR Rate Advances if such Lender may lawfully continue to maintain and fund such LIBOR Rate Advances to such day(s) or (2) immediately if such Lender may not lawfully continue to fund and maintain such LIBOR Rate Advances to such day(s), provided that in such event the conversion shall not be subject to payment of a prepayment fee under Section 3.5(d). Each Lender agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will cause that Lender to notify the Administrative Agent under this Section, and agrees to designate a different LIBOR Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender. In the event that any Lender is unable, for the reasons set forth above (or those set forth in clause (c) below), to make, maintain or fund its portion of any LIBOR Rate Loan, such Lender shall fund such amount as an Alternate Base Rate Advance for the same period of time, and such amount shall be treated in all respects as an Alternate Base Rate Advance. Any Lender whose obligation to make LIBOR Rate Advances has been suspended under this Section shall promptly notify the Administrative Agent and Borrower of the cessation of the Special LIBOR Circumstance which gave rise to such suspension.

          (c) If, with respect to any proposed LIBOR Rate Loan:

               (i) the Administrative Agent reasonably determines that, by reason of circumstances affecting the London interbank market generally that are beyond the reasonable control of the Lenders, deposits in Dollars (in the applicable amounts) are not being offered to any Lender in the London interbank market for the applicable LIBOR Period; or

               (ii) the Requisite Lenders advise the Administrative Agent that the LIBOR Rate as determined by the Administrative Agent (i) does not represent the effective pricing to such Lenders for deposits in Dollars in the London interbank market in the relevant amount for

the applicable LIBOR Period, or (ii) will not adequately and fairly reflect the cost to such Lenders of making the applicable LIBOR Rate Advances;

then the Administrative Agent forthwith shall give notice thereof to Borrower and the Lenders, whereupon until the Administrative Agent notifies Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of the Lenders to make any future LIBOR Rate Advances shall be suspended.

          (d) Except for a failure caused by any Lender’s default, Borrower shall indemnify the Lenders against any loss or expense that the Lenders may sustain or incur (including, without limitation, any loss or expense sustained or incurred in obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any LIBOR Rate Loans) as a consequence of (i) any failure of Borrower to make any payment when due of any amount due hereunder, (ii) any failure of Borrower to borrow, continue or convert a LIBOR Rate Loan on a date specified therefor in a notice thereof, (iii) any failure to fulfill on the scheduled commencement date of any LIBOR Period hereunder the applicable conditions set forth herein as prerequisites to an Advance that is to be a LIBOR Rate Loan or to the election of a LIBOR Rate, (iv) any failure to borrow hereunder after a request for a LIBOR Rate Loan has been given, (v) any payment or prepayment permitted or mandated hereunder of a LIBOR Rate Loan on a date other than the last day of the relevant LIBOR Period, including without limitation upon acceleration following an Event of Default, or (vi) the occurrence of any Event of Default, including but not limited to any loss or expense sustained or incurred or to be sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain a LIBOR Rate Loan. Without limiting the foregoing, such loss or expense shall conclusively be deemed to include a “Breakage Fee” (as defined below). The term “Breakage Fee” shall mean that sum equal to the greater of $200 or the financial loss incurred by the Lenders resulting from prepayment or failure to borrow, calculated by the Administrative Agent as the difference between the amount of interest the Lenders would have earned (from like investments in the Money Markets (as hereinafter defined) as of the first day of the applicable LIBOR Period) had prepayment or failure to borrow not occurred and the interest the Lenders would actually earn (from like investments in the Money Markets as of the date of prepayment or failure to borrow) as a result of the redeployment of funds from the prepayment or failure to borrow. Borrower agrees that the Breakage Fee shall not be discounted to its present value. Any voluntary prepayment of a LIBOR Rate Loan shall be in an amount equal to the remaining entire principal balance of such LIBOR Rate Loan. The term “Money Markets” refers to one or more wholesale funding markets available to Lenders, including negotiable certificates of deposit, commercial paper, Eurodollar deposits, bank notes, federal funds and others. The Administrative Agent shall provide to Borrower a statement, signed by an officer of the Administrative Agent, explaining any such loss or expense and setting forth the computation of the Breakage Fee pursuant to the preceding provisions which, in the absence of manifest error, shall be conclusive and binding on Borrower.

          (e) Each Lender agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will entitle such Lender to compensation pursuant to this Section 3.5, and agrees to designate a different LIBOR Lending Office if such designation will avoid the need for or reduce the amount of such compensation and

- 34 -

will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender. Any request for compensation by a Lender under this Section 3.5 shall set forth the basis upon which it has been determined that such an amount is due from Borrower, a calculation of the amount due, and a certification that the corresponding costs have been incurred by the Lender.

     3.6 Late Payments. If any installment of principal or interest or any fee or cost or other amount payable under any Loan Document to the Administrative Agent or any Lender is not paid when due, it shall thereafter bear interest at a fluctuating interest rate per annum (the “Default Rate”) at all times equal to (i) in the case of interest or principal, the sum of the rate otherwise applicable to the Loans, plus 3% and (ii) in the case of any other amount, the sum of the Alternate Base Rate plus 3%, to the fullest extent permitted by applicable Laws. Accrued and unpaid interest on past due amounts (including, without limitation, interest on past due interest) shall be compounded monthly, on the last day of each calendar month, to the fullest extent permitted by applicable Laws, and shall be payable upon demand. In addition, Borrower shall pay, upon demand, a late charge equal to five percent (5%) of any amount of interest and/or principal payable on the Loans or any other amounts payable hereunder or under the other Loan Documents which is not paid within ten (10) days of the date when due.

     3.7 Computation of Interest and Fees. Computation of interest and fees under this Agreement shall be calculated on the basis of a year of 360 days and the actual number of days elapsed, except that interest at the Alternate Base Rate shall be calculated on the basis of a 365 or 366 day year, as applicable. Interest shall accrue on each Loan for the day on which the Loan is made; interest shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid. Any Loan that is repaid on the same day on which it is made shall bear interest for one day. Notwithstanding anything in this Agreement to the contrary, interest in excess of the maximum amount permitted by applicable Laws shall not accrue or be payable hereunder or under the Notes, and any amount paid as interest hereunder or under the Notes which would otherwise be in excess of such maximum permitted amount shall instead be treated as a payment of principal.

     3.8 Non Banking Days. If any payment to be made by Borrower or any other Party under any Loan Document shall come due on a day other than a Banking Day, payment shall instead be considered due on the next succeeding Banking Day, unless, in the case of a payment relating to a LIBOR Rate Loan, such next succeeding Banking Day is in the next calendar month, in which case such payment shall be made on the next preceding Banking Day, but the extension of time shall not be reflected in computing interest and fees.

     3.9 Manner and Treatment of Payments.

          (a) Each payment hereunder (except payments pursuant to Sections 3.4, 3.5, 18.3, 18.11 and 18.22) or on the Notes or under any other Loan Document shall be made to the Administrative Agent at the Administrative Agent’s Office for the account of each of the Lenders or the Administrative Agent, as the case may be, in immediately available funds not later than 2:00 p.m., Cleveland time, on the day of payment (which must be a Banking Day). All payments received after such time, on any Banking Day, shall be deemed received on the next succeeding Banking Day. The amount of all payments received by the Administrative Agent for the account of each Lender shall be immediately paid by the Administrative Agent to the applicable Lender in

- 35 -

immediately available funds and, if such payment was received by the Administrative Agent by 2:00 p.m., Cleveland time, on a Banking Day and not so made available to the account of a Lender on that Banking Day, the Administrative Agent shall reimburse that Lender for the cost to such Lender of funding the amount of such payment at the Federal Funds Effective Rate. All payments shall be made in Dollars.

          (b) Each payment or prepayment shall be applied first to Alternate Base Rate Loans and then to LIBOR Rate Loans. Each payment or prepayment on account of any such Alternate Base Rate Loan or LIBOR Rate Loan shall be applied pro rata according to the outstanding Advances made by each Lender comprising such Loan.

          (c) Each Lender shall keep a record (in writing or by an electronic data entry system) of Advances made by it and payments received by it with respect to each of its Notes and, subject to Section 17.6(g), such record shall, as against Borrower, be presumptive evidence of the amounts owing, absent manifest error. Notwithstanding the foregoing sentence, the failure by any Lender to keep such a record shall not affect Borrower’s obligation to pay the Obligations.

          (d) Each payment of any amount payable by Borrower or any other Party under this Agreement or any other Loan Document shall be made without setoff or counterclaim and free and clear of, and without reduction by reason of, any taxes, assessments or other charges imposed by any Governmental Agency, central bank or comparable authority, excluding (i) taxes imposed on or measured in whole or in part by any Lender’s overall net income (including taxes on gross income imposed in lieu of net income tax, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which such Lender is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which such Lender is “doing business” and (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which any Lender has failed, for whatever reason, timely to provide Borrower with the appropriate form or forms required by Section 18.21, to the extent such forms are then required by applicable Laws to establish a complete exemption (all such non excluded taxes, assessments or other charges being hereinafter referred to as “Taxes”). To the extent that Borrower is obligated by applicable Laws to make any deduction or withholding on account of Taxes from any amount payable to any Lender under this Agreement, Borrower shall (i) make such deduction or withholding and pay the same to the relevant Governmental Agency and (ii) pay such additional amount to that Lender as is necessary to result in that Lender’s receiving a net after Tax amount equal to the amount to which that Lender would have been entitled under this Agreement absent such deduction or withholding.

     3.10 Funding Sources. Nothing in this Agreement shall be deemed to obligate any Lender to obtain the funds for any Loan or Advance in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan or Advance in any particular place or manner.

     3.11 Failure to Charge Not Subsequent Waiver. Any decision by the Administrative Agent or any Lender not to require payment of any interest (including interest arising under Section 3.6), fee, cost or other amount payable under any Loan Document, or to calculate any amount payable by a particular method, on any occasion shall in no way limit or be deemed a waiver of the

Administrative Agent’s or such Lender’s right to require full payment of any interest (including interest arising under Section 3.6), fee, cost or other amount payable under any Loan Document, or to calculate an amount payable by another method that is not inconsistent with this Agreement, on any other or subsequent occasion.

     3.12 Administrative Agent’s Right to Assume Payments Will be Made by Borrower. Unless the Administrative Agent shall have been notified by Borrower prior to the date on which any payment to be made by Borrower hereunder is due that Borrower does not intend to remit such payment, the Administrative Agent may, in its discretion, assume that Borrower has remitted such payment when so due and the Administrative Agent may, in its discretion and in reliance upon such assumption, make available to each Lender on such payment date an amount equal to such Lender’s share of such assumed payment. If Borrower has not in fact remitted such payment to the Administrative Agent, each Lender shall forthwith on demand repay to the Administrative Agent the amount of such assumed payment made available to such Lender, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent at the Federal Funds Effective Rate.

     3.13 Calculations Detail. The Administrative Agent, and any Lender, shall provide reasonable detail to Borrower regarding the manner in which the amount of any payment to the Administrative Agent and the Lenders, or that Lender, under Article 3 has been determined, within a reasonable period of time after request by Borrower.

     3.14 Survivability. The provisions of Sections 3.4 and 3.5 shall survive following the date on which the Commitments are terminated and all Loans hereunder are fully paid, and Borrower shall remain obligated thereunder for all claims under such Sections made by any Lender to Borrower.

               (i) such Pension Plan complies in all material respects with ERISA and any other applicable Laws to the extent that noncompliance would constitute a Material Adverse Effect;

     4.18 Property. All of the Loan Parties’ and their respective Subsidiaries’ properties are in good repair and condition, subject to ordinary wear and tear, other than with respect to (i) deferred maintenance existing as of the date of acquisition of such property as permitted in this Section 4.18, (ii) Projects currently under development and (iii) defects relating to properties other than the Subject Property which would not constitute a Material Adverse Effect. The Loan Parties further have completed or caused to be completed an appropriate investigation of the environmental

There are no unpaid or outstanding real estate or other taxes or assessments on or against any property of any Loan Party or any of their respective Subsidiaries which are payable by such Person (except only real estate or other taxes or assessments, that are not yet due and payable). There are no pending eminent domain proceedings against the Subject Property, and, to the knowledge of Borrower, no such proceedings are presently threatened by any taking authority which individually or in the aggregate would constitute a Material Adverse Effect. None of the property of the Loan Parties or their respective Subsidiaries is now damaged or injured as a result of any fire, explosion, accident, flood or other casualty in any manner which individually or in the aggregate would constitute a Material Adverse Effect.

     4.19 Brokers. None of the Loan Parties or their respective Subsidiaries has engaged or otherwise dealt with any broker, finder or similar entity in connection with this Agreement or the Loans contemplated hereunder.

     4.20 Other Debt.

     4.21 Solvency. As of the Closing Date and after giving effect to the transactions contemplated by this Agreement and the other Loan Documents, including all of the Loans made or to be made hereunder, none of the Loan Parties (taken on a consolidated basis) is insolvent on a balance sheet basis such that the sum of such Person’s assets exceeds the sum of such Person’s liabilities (taken on a consolidated basis), each Loan Party is able to pay its debts as they become due, and each Loan Party has sufficient capital to carry on its business.

     4.22 No Fraudulent Intent. Neither the execution and delivery of this Agreement or any of the other Loan Documents nor the performance of any actions required hereunder or thereunder is being undertaken by any Loan Party with or as a result of any actual intent by any of such Persons to hinder, delay or defraud any entity to which any of such Persons is now or will hereafter become indebted.

     4.23 Transaction in Best Interests of Loan Parties; Consideration. The transaction evidenced by this Agreement and the other Loan Documents is in the best interests of the Loan

Parties. The direct and indirect benefits to inure to the Loan Parties pursuant to this Agreement and the other Loan Documents constitute substantially more than “reasonably equivalent value” (as such term is used in Section 548 of the Bankruptcy Code) and “valuable consideration,” “fair value,” and “fair consideration” (as such terms are used in any applicable state fraudulent conveyance law), in exchange for the benefits to be provided by the Loan Parties pursuant to this Agreement and the other Loan Documents, and but for the willingness of the Loan Parties to be jointly and severally liable as co Loan obligor for the Loan, Loan Parties would be unable to obtain the financing contemplated hereunder which financing will enable the Loan Parties and their respective Subsidiaries to have available financing to conduct and expand their business.

     4.24 No Bankruptcy Filing. None of the Loan Parties or any of their respective Subsidiaries is contemplating either the filing of a petition by it under any state or federal bankruptcy or insolvency laws or the liquidation of its Property, and none of the Loan Parties has any knowledge of any Person contemplating the filing of any such petition against it or any Subsidiary.

Borrower is unaware of any other such costs, expenses or fees which are material and are not covered by the Budget.

     (i) Borrower has not made any material contract or arrangement, the performance of which by the other party thereto could give rise to a lien on the Subject Property or any portion thereof, except for the Permitted Exceptions, the Leases and its agreements with the General Contractor, the Architect, certain consultancy agreements and their agreements with various subcontractors and material suppliers, all of which have been disclosed in writing to the Administrative Agent or are set forth in the Budget.

All Leases are in full force and effect. Borrower is not in default under any Lease and Borrower has disclosed to Lenders in writing any material default, of which Borrower has knowledge, by the tenant under any Lease.

     (l) When the Construction is completed in accordance with the Plans and Specifications, no building or other improvement will encroach upon any property line, building line, setback line, side yard line or any recorded or visible easement (or other easement of which Borrower is aware or has reason to believe may exist) with respect to the Subject Property.

     (m) To the Borrower’s knowledge, there are no material delinquent taxes, ground rents, water charges, sewer rents, assessments, insurance premiums, leasehold payments, or other outstanding charges affecting the Subject Property except to the extent such items are being contested in good faith and as to which adequate reserves have been provided.

ARTICLE 8

BUDGET AND CONTINGENCY FUND

     8.1 Budget. Disbursement of the Loan shall be governed by a budget for the Subject Property (the “Budget”), in form and substance acceptable to Administrative Agent in Administrative Agent’s reasonable discretion, specifying the amount of cash equity invested in the Subject Property and all costs and expenses of every kind and nature whatever to be incurred by Borrower in connection with the Subject Property prior to the Maturity Date as described more fully in Section 8.2 below. The Budget shall include, in addition to the Budget Line Items described in Section 8.2 below, the Contingency Fund described in Section 8.3 below, and amounts satisfactory to Administrative Agent for soft costs and other reserves acceptable to Administrative Agent. The initial Budget is attached hereto as Exhibit G and made a part hereof. Except as expressly provided herein to the contrary, all changes to the Budget shall in all respects be subject to the prior written approval of Administrative Agent. Changes in the scope of construction work or to any construction related contract must be documented with a change order on the AIA Form G 701 or equivalent form.

     8.2 Budget Line Items. The Budget shall include as line items (“Budget Line Items”), to the extent determined to be applicable by Administrative Agent in its reasonable discretion, the cost of all labor, materials, equipment, fixtures and furnishings needed for the completion of Construction, and all other costs, fees and expenses relating in any way whatsoever to the Construction of the Improvements, leasing commissions, tenant improvements and tenant allowances, operating deficits, real estate taxes, and all other sums due in connection with Construction and operation of the Subject Property, the Loan, and this Agreement. Borrower agrees that all Loan proceeds shall be used only for the Budget Line Items for which such proceeds were disbursed.

     Without limiting Borrower’s rights under Section 8.3 below, Borrower shall have the right to reallocate cost savings effected by final change order or other appropriate final documentation to

other Budget Line Items subject to Administrative Agent’s prior written consent not to be unreasonably withheld.

     Lenders shall not be obligated to disburse any amount for any category of costs set forth as a Budget Line Item which is greater than the amount set forth for such category in the applicable Budget Line Item. Borrower shall pay as they become due all amounts set forth in the Budget with respect to costs to be paid for by Borrower.

     8.3 Contingency Fund. The Budget contains a line item titled “Hard Cost Contingency” designated for contingency (“Contingency Fund”) which shall represent an amount necessary to provide reasonable assurances to Lenders that additional funds are available to be used if additional costs and expenses are incurred or additional interest accrues on the Loan, or unanticipated events or problems occur. Borrower may from time to time request that the Contingency Fund be reallocated to pay needed Project Costs of the Subject Property. Borrower shall have the right to reallocate amounts from the Contingency Fund, without the prior written approval of the Administrative Agent, to the extent that the sum remaining in the Contingency Fund, following such reallocation, represents at least 1.5% of the remaining amount in the line item for Hard Costs (Lab Tower & Garage) on Exhibit I. Requests to reallocate the Contingency Fund in excess of such amounts shall be subject to Administrative Agent’s written approval in its reasonable discretion.

     Borrower agrees that the decision with respect to utilizing portions of the Contingency Fund in order to keep the Loan “In Balance” shall, except as provided in the preceding paragraph of this Section 8.3, be made by the Administrative Agent in its reasonable discretion, and that the Administrative Agent may require Borrower to make a Deficiency Deposit even if funds remain in the Contingency Fund.

     8.4 Optional Method for Payment of Interest. For Borrower’s benefit, the Budget includes a Budget Line Item for interest. Borrower hereby authorizes the Administrative Agent from time to time, for the mutual convenience of Lenders and Borrower, to disburse Loan proceeds to pay all the then accrued interest on the Notes, regardless of whether Borrower shall have specifically requested a disbursement of such amount. Any such disbursement, if made, shall be added to the outstanding principal balance of the Note. The authorization hereby granted, however, shall not obligate Lender to make disbursements of the Loan for interest payments (except upon Borrower’s qualifying for and requesting disbursement of that portion of the proceeds of the Loan allocated for such purposes in the Budget) nor prevent Borrower from paying accrued interest from its own funds. Once the Subject Property begins to generate Net Operating Income, Borrower may only borrow from the Loan interest in excess of the Net Operating Income so generated.

ARTICLE 9

SUFFICIENCY OF LOAN

     9.1 Loan In Balance. Anything in this Agreement contained to the contrary notwithstanding, it is expressly understood and agreed that in the Administrative Agent’s reasonable discretion the Loan shall at all times be “In Balance” on a line-by-line and an aggregate basis. Each line item in the Budget shall be deemed to be “In Balance” only when the undisbursed portion of

the then-current line item equals or exceeds the costs required to complete all elements of the construction of the Subject Property intended to be covered by such line item. The Loan shall be deemed to be “In Balance” in the aggregate only when the total of the undisbursed portion of the then-current Maximum Loan Amount less the Contingency Fund (subject to Borrower’s reallocation rights under Sections 8.2 and 8.3), equals or exceeds the aggregate of (a) the costs required to complete the construction of the Subject Property in accordance with the Plans and Specifications and the Budget, including, without limitation, all Tenant Work required to be performed by Borrower or tenant allowances to be paid for by Borrower under Leases or reasonably anticipated for unleased space; (b) the amounts to be paid as retainages to persons who have supplied labor or materials to the Subject Property; (c) the amount in excess of projected Net Operating Income required to pay interest on the Loan through the Maturity Date; and (d) all other hard and soft costs not yet paid for in connection with the Subject Property. Such costs and amounts described in clauses (a), (b), (c) and (d) may be estimated and/or approved in writing by the Administrative Agent from time to time. Borrower agrees that if for any reason, in the Administrative Agent’s reasonable discretion, the amount of such undistributed Loan proceeds shall at any time be or become insufficient for such purpose regardless of how such condition may be caused, Borrower will, within ten (10) days after written request by the Administrative Agent, deposit the deficiency with the Administrative Agent (“Deficiency Deposit”). The Deficiency Deposit shall first be exhausted before any further disbursement of Loan proceeds shall be made. Lenders shall not be obligated to make any Loan disbursements if and for as long as the Loan is not “In Balance”. Notwithstanding anything contained herein to the contrary, if, as a result of any subsequent events, such Deficiency Deposit is no longer needed in order for the Loan to be “In Balance”, then to the extent that any portion of such Deficiency Deposit has not otherwise been applied to Project Costs, such Deficiency Deposit funds held by Administrative Agent shall be returned to Borrower.

ARTICLE 10

          (c) Paid invoices or other evidence satisfactory to the Administrative Agent that fixtures and equipment have been paid for and are free of any lien or security interest therein;

          (d) An endorsement to the Title Policy issued to the Administrative Agent on behalf of the Lenders covering the date not more than twenty-nine (29) days prior to the date of disbursement, increasing the insured amount to the then-current Outstanding Loan Amount (after giving effect to such disbursement) and showing the Mortgage as a first and prior lien on the Subject Property subject only to the Permitted Exceptions and particularly that nothing has intervened to affect the validity or priority of the Mortgage;

          (e) Copies of any change orders, whether proposed or executed, which have not been previously furnished to the Administrative Agent;

     10.4 Retainages. At the time of each disbursement of Loan proceeds, ten percent (10%) of the total amount then due the General Contractor and the various contractors, subcontractors and material suppliers for costs of Construction shall be withheld from the amount disbursed until 50% completion of the Construction is achieved. No further retainage shall be withheld from amounts disbursed after 50% Construction completion is achieved. On the Closing Date, Borrower shall deliver to Administrative Agent the same statement regarding the General Contract that is provided to Borrower in connection with its acquisition of the Subject Property, which statement shall confirm the retainage that has been withheld from the General Contractor, and that the Budget includes the appropriate retainage, given the then-current status of Construction and all prior payments to the General Contractor. The retained Loan amounts for Construction costs will be disbursed only at the time of the final disbursement of Loan proceeds under Article 11 below; provided, however, upon the satisfactory completion of one hundred percent (100%) of the work with respect to any trade (including any trade performed by General Contractor) or the delivery of all materials pursuant to a purchase order in accordance with the Plans and Specifications as

certified by the Architect and Lenders’ Consultant, the retainages with respect to such trade or order, as the case may be, shall be disbursed to Borrower within thirty (30) days after Lenders’ Consultant’s approval of all work and materials and the Administrative Agent’s receipt of a final waiver of lien with respect to such completed work or delivered materials.

     10.5 Disbursements for Materials Stored On-Site. Any requests for disbursements which in whole or in part relate to materials, equipment or furnishings which Borrower owns and which are not incorporated into the Improvements as of the date of the request for disbursement, but are to be temporarily stored at the Subject Property, shall be made in an aggregate amount not to exceed the amounts set forth in the Budget. Any such request must be accompanied by evidence satisfactory to Administrative Agent that (i) such stored materials are included within the coverages of insurance policies carried by Borrower, (ii) the ownership of such materials is vested in Borrower free of any liens and claims of third parties, (iii) such materials are properly insured and protected against theft or damage, (iv) the materials used in the Construction are not commodity items but are uniquely fabricated for the Construction, (v) if requested by the Administrative Agent, the Lenders’ Consultant has viewed and inspected the stored materials, and (vi) if so requested by Administrative Agent, in the reasonable opinion of the Lenders’ Consultant the stored materials are physically secured and can be incorporated into the Subject Property within forty five (45) days. Administrative Agent may require separate Uniform Commercial Code financing statements to cover any such stored materials.

     10.6 Disbursements for Offsite Materials. Except to the extent expressly provided in the Budget, Administrative Agent may in its sole discretion, but shall not be obligated to, make disbursements for materials stored off-site, in which event all of the requirements of Section 10.5 (i)-(v) shall be applicable to such disbursement as well as any other requirements with the Administrative Agent may, in its sole discretion, determine are appropriate under the circumstances.

     10.7 Disbursements For Tenant Work and Allowances.

          (a) Lenders will agree to make interim disbursements for Tenant Work or tenant allowances for Tenants under Approved Leases as required to comply with the terms of any such Lease.

          (b) The first request for disbursement for Tenant Work in connection with a specific leased space in the Subject Property shall be accompanied by the following, all of which shall be subject to the reasonable approval of Administrative Agent:

                    (i) copies of all contracts, if not previously delivered to Administrative Agent, for the performance of such Tenant Work;

          (a) Upon the occurrence and during the continuance of any Event of Default, Administrative Agent, on behalf of the Lender, may take possession of the Subject Property and complete the Construction and do anything which is necessary or appropriate in its sole judgment to fulfill the obligations of Borrower under this Agreement and the other Loan Documents, including either the right to avail itself of and procure performance of existing contracts or let any contracts with the same contractors or others. Without restricting the generality of the foregoing and for the purposes aforesaid, Borrower hereby appoints and constitutes Administrative Agent its lawful attorney-in-fact with full power of substitution in the Subject Property to complete the Construction in the name of Borrower; to use unadvanced funds remaining under the Loan or which may be reserved, escrowed or set aside for any purposes hereunder at any time, or to advance funds in excess of the Maximum Loan Amount, to complete the Construction; to make changes in the Plans and Specifications which shall be necessary or desirable to complete the Construction in substantially the manner contemplated by the Plans and Specifications; to retain or employ new general contractors, subcontractors, architects, engineers and inspectors as shall be required for said purposes; to pay, settle or compromise all existing bills and claims, which may be liens or security interests, or to avoid such bills and claims becoming liens against the Subject Property; to execute all applications and certificates in the name of Borrower prosecute and defend all actions or proceedings in connection with the Improvements or the Subject Property; to take action and require such performance as it deems necessary under any of the Bonds to be furnished hereunder and to make settlements and compromises with the surety or sureties thereunder, and in connection therewith, to execute instruments of release and satisfaction; and to do any and every act which the Borrower might do in its own behalf; it being understood and agreed that this power of attorney shall be a power coupled with an interest and cannot be revoked.

          (b) Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent may withhold further disbursement of the proceeds of the Loan and/or terminate the Lenders’ obligations to make further disbursements hereunder.

          (c) Upon the occurrence, and during the continuance, of any Event of Default other than an Event of Default described in Section 16.1(o), the Requisite Lenders may request the Administrative Agent to, and the Administrative Agent thereupon shall, declare all or any part of the unpaid principal of all Notes, all interest accrued and unpaid thereon and all other amounts payable under the Loan Documents to be forthwith due and payable, whereupon the same shall become and be forthwith due and payable, without protest, presentment, notice of dishonor, demand or further notice of any kind, all of which are expressly waived by Borrower, and Lenders’ Commitments to make further disbursements hereunder shall be terminated immediately without any further action.

          (d) Upon the occurrence and during the continuance of any Event of Default described in Section 16.1(o), the unpaid principal of all Notes, all interest accrued and unpaid thereon and all other amounts payable under the Loan Documents shall be forthwith due and payable, all without protest, presentment, notice of dishonor, demand or further notice of any kind, all of which are expressly waived by Borrower.

          (e) Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent, on behalf of the Lenders, without notice to (except as expressly provided for in any Loan Document) or demand upon Borrower, which are expressly waived by Borrower (except as to notices expressly provided for in any Loan Document), may proceed (but only with the consent of the Requisite Lenders) to protect, exercise and enforce their rights and remedies under the Loan Documents against Borrower and any other Loan Party and such other rights and remedies as are provided by Law or equity.

          (f) The order and manner in which the Lenders’ rights and remedies are to be exercised shall be determined by the Requisite Lenders in their sole discretion, and all payments received by the Administrative Agent and the Lenders, or any of them, shall be applied first to the costs and expenses (including reasonable attorneys’ fees and disbursements and the reasonably allocated costs of attorneys employed by the Administrative Agent or by any Lender) of the Administrative Agent and of the Lenders, then to the repayment of the Loans, and thereafter paid pro rata to the Lenders in the same proportions that the aggregate Obligations owed to each Lender under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all the Lenders, without priority or preference among the Lenders. Regardless of how each Lender may treat payments for the purpose of its own accounting, for the purpose of computing the Obligations hereunder and under the Notes, payments shall be applied first, to the costs and expenses of the Administrative Agent and the Lenders, as set forth above, second, to the payment of accrued and unpaid interest due under any Loan Documents to and including the date of such application (ratably, and without duplication, according to the accrued and unpaid interest due under each of the Loan Documents), and third, pari passu to the payment of all other amounts (including principal and fees) then owing to the Administrative Agent or the Lenders under the Loan Documents and to the payment of any termination payments due from Borrower in respect of Swap Agreements. No application of payments under this clause (f) will cure any Event of Default, or prevent acceleration, or continued acceleration, of amounts payable under the Loan Documents, or prevent the exercise, or continued exercise, of rights or remedies of the Lenders hereunder or thereunder or at Law or in equity.

ARTICLE 17

THE ADMINISTRATIVE AGENT

     17.1 Appointment and Authorization. Subject to Section 17.8, each Lender hereby irrevocably appoints and authorizes the Administrative Agent to take such action as the contractual representative on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms thereof or are reasonably incidental, as determined by the Administrative Agent, thereto. This appointment and authorization is intended solely for the

purpose of facilitating the servicing of the Loans and does not constitute appointment of the Administrative Agent as trustee for any Lender or as representative of any Lender for any other purpose and, the Administrative Agent shall take such action and exercise such powers only in an administrative and ministerial capacity.

     17.2 Administrative Agent and Affiliates. KeyBank (and each successor Administrative Agent in its individual capacity) has the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” includes KeyBank in its individual capacity. KeyBank (and each successor Administrative Agent in its individual capacity) and its Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with Borrower or any other member of the Consolidated Group, as if it were not the Administrative Agent and without any duty to account therefor to the Lenders. KeyBank (and each successor Administrative Agent in its individual capacity) need not account to any other Lender for any monies received by it for reimbursement of its costs and expenses as the Administrative Agent hereunder, or for any monies received by it in its capacity as a Lender hereunder, other than as required of any Lender hereunder. The Administrative Agent shall not be deemed to hold a fiduciary or agency relationship with any Lender and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against the Administrative Agent.

     17.3 Proportionate Interest in any Collateral. The Administrative Agent, on behalf of all the Lenders, shall hold in accordance with the Loan Documents all items of collateral (if any) or interests therein received or held by the Administrative Agent. Subject to the Administrative Agent’s and the Lenders’ rights to reimbursement for their costs and expenses hereunder (including reasonable attorneys’ fees and disbursements and other professional services and the reasonably allocated costs of attorneys employed by the Administrative Agent or, upon the occurrence and during the continuation of an Event of Default, a Lender) and subject to the application of payments in accordance with Section 16.2(f), each Lender shall have an interest in the Administrative Agent’s interest in such collateral (if any) or interests therein in the same proportions that the aggregate Obligations owed such Lender under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all the Lenders, without priority or preference among the Lenders.

     17.4 Lenders’ Credit Decisions. Each Lender agrees that it has, independently and without reliance upon the Administrative Agent, any other Lender or the directors, officers, agents, employees or attorneys of the Administrative Agent or of any other Lender, and instead in reliance upon information supplied to it by or on behalf of Borrower and upon such other information as it has deemed appropriate, made its own independent credit analysis and decision to enter into this Agreement. Each Lender also agrees that it shall, independently and without reliance upon the Administrative Agent, any other Lender or the directors, officers, agents, employees or attorneys of the Administrative Agent or of any other Lender, continue to make its own independent credit analyses and decisions in acting or not acting under the Loan Documents.

     17.5 Action by Administrative Agent.

          (a) Absent actual knowledge of the Administrative Agent of the existence of a Default, the Administrative Agent may assume that no Default (other than the failure to make a payment of principal or interest when due) has occurred and is continuing, unless the Administrative Agent has received notice from Borrower stating the nature of the Default or has received notice from a Lender stating the nature of the Default and that such Lender considers the Default to have occurred and to be continuing.

          (b) The Administrative Agent has only those obligations under the Loan Documents as are expressly set forth therein.

          (c) Except for any obligation expressly set forth in the Loan Documents and as long as the Administrative Agent may assume that no Default has occurred and is continuing, the Administrative Agent may, but shall not be required to, exercise its discretion to act or not act, except that the Administrative Agent shall be required to comply with the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 12.1) and those instructions shall be binding upon the Administrative Agent and all the Lenders, provided that the Administrative Agent shall not be required to comply with such instructions if to do so would be contrary to any Loan Document or to applicable Law or would result, in the reasonable judgment of the Administrative Agent, in substantial risk of liability to the Administrative Agent.

          (d) If the Administrative Agent has received a notice specified in clause (a) or has actual knowledge of the existence of a Default, the Administrative Agent shall promptly give notice thereof to the Lenders and shall comply with the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 19.1), provided that the Administrative Agent shall not be required to comply with such instructions if to do so would be contrary to any Loan Document or to applicable Law or would result, in the reasonable judgment of the Administrative Agent, in substantial risk of liability to the Administrative Agent, and except that if the Requisite Lenders (or all the Lenders, if required under Section 19.1) fail, for five (5) Banking Days after the receipt of notice from the Administrative Agent, to instruct the Administrative Agent, then the Administrative Agent, in its sole discretion, may act or not act as it deems advisable for the protection of the interests of the Lenders.

     17.6 Liability of Administrative Agent. Neither the Administrative Agent nor any of its directors, officers, agents, employees or attorneys shall be liable for any action taken or not taken by them under or in connection with the Loan Documents, except for their own gross negligence or willful misconduct. Without limitation on the foregoing, the Administrative Agent and its directors, officers, agents, employees and attorneys:

          (a) May treat the payee of any Note as the holder thereof until the Administrative Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent, signed by the payee, and may treat each Lender as the owner of that Lender’s interest in the Obligations for all purposes of this Agreement until the Administrative Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent, signed by that Lender;

          (b) May consult with legal counsel (including in house legal counsel), accountants (including in house accountants) and other professionals or experts selected by it, or with legal counsel, accountants or other professionals or experts for the Consolidated Group or the Lenders, and shall not be liable for any action taken or not taken by it in good faith in accordance with any advice of such legal counsel, accountants or other professionals or experts;

          (c) Shall not be responsible to any Lender for any statement, warranty or representation made in any of the Loan Documents or in any notice, certificate, report, request or other statement (written or oral) given or made in connection with any of the Loan Documents;

          (d) Shall have no duty to ask or inquire as to the performance or observance by Borrower or the Loan Parties of any of the terms, conditions (except to ascertain that documents facially responsive to the requirements of Section 6.1(a) have been delivered) or covenants of any of the Loan Documents or to inspect any collateral or any Property, books or records of the Loan Parties;

          (e) Will not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, effectiveness, sufficiency or value of any Loan Document, any other instrument or writing furnished pursuant thereto or in connection therewith, or any collateral;

          (f) Will not incur any liability by acting or not acting in reliance upon any Loan Document, notice, consent, certificate, statement, request or other instrument or writing believed in good faith by it to be genuine and signed or sent by the proper party or parties;

          (g) Will not incur any liability for any arithmetical error in computing any amount paid or payable by Borrower or any other Loan Party thereof or paid or payable to or received or receivable from any Lender under any Loan Document, including, without limitation, principal, interest, commitment fees, Advances and other amounts; provided that, promptly upon discovery of such an error in computation, the Administrative Agent, the Lenders and (to the extent applicable) Borrower and/or the other Loan Parties shall make such adjustments as are necessary to correct such error and to restore the parties to the position that they would have occupied had the error not occurred; and

          (h) Have not made nor do they now make any representations or warranties, express or implied, nor do they assume any liability to the Lenders, with respect to the creditworthiness or financial condition of the Consolidated Group, the value of their respective assets or the collectability of the Loans.

     17.7 Indemnification. Each Lender shall, ratably in accordance with its Percentage of the aggregate Indebtedness then evidenced by the Notes, indemnify and hold the Administrative Agent and its directors, officers, agents, employees and attorneys harmless against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees and disbursements and allocated costs of attorneys employed by the Administrative Agent) that may be imposed on, incurred by or asserted against it or them in any way relating to or arising out of the Loan Documents (other than losses incurred by reason of the failure of Borrower to pay the Indebtedness

represented by the Notes) or any action taken or not taken by it as the Administrative Agent thereunder, except such as result from its own gross negligence or willful misconduct. Without limitation on the foregoing, each Lender shall reimburse the Administrative Agent upon demand for that Lender’s Percentage of any out of pocket cost or expense incurred by the Administrative Agent in connection with the negotiation, preparation, execution, delivery, amendment, waiver, restructuring, reorganization (including a bankruptcy reorganization), enforcement or attempted enforcement of the Loan Documents, to the extent that any Borrower or any other Loan Party is required by Section 18.3 to pay that cost or expense but fails to do so upon demand. Nothing in this Section 17.7 shall entitle the Administrative Agent or any indemnitee referred to above to recover any amount from the Lenders if and to the extent that such amount has theretofore been recovered from Borrower or any other Loan Party. To the extent that the Administrative Agent or any indemnitee referred to above is later reimbursed such amount by Borrower or any other Loan Party, it shall return the amounts paid to it by the Lenders in respect of such amount.

     17.8 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon reasonable notice to the Lenders and Borrower effective not earlier than thirty (30) days after such notice, upon acceptance of appointment by a successor Administrative Agent. The Requisite Lenders may (with the prior consent, not to be unreasonably withheld or delayed, of Trust, unless an Event of Default shall have occurred and be continuing) remove the Administrative Agent from its capacity as Administrative Agent in the event of the Administrative Agent’s willful misconduct or gross negligence. If the Administrative Agent shall resign or be removed as Administrative Agent under this Agreement, the Requisite Lenders shall appoint from among the Lenders a successor Administrative Agent for the Lenders, which successor Administrative Agent shall require approval by Trust so long as no Default or Event of Default has occurred and is continuing (and such approval shall not be unreasonably withheld or delayed). If no successor Administrative Agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders and, so long as no Default or Event of Default has occurred and is continuing, with the consent of Trust, a successor Administrative Agent from among the Lenders. Upon the acceptance of its appointment as successor Administrative Agent hereunder, such successor Administrative Agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor Administrative Agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article 17, and Sections 18.3, 18.11 and 18.22, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if no successor Administrative Agent has accepted appointment as Administrative Agent by the date which is thirty (30) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Administrative Agent as provided for above.

     17.9 No Obligations of Borrower. Nothing contained in this Article 17 shall be deemed to impose upon Borrower any obligation in respect of the due and punctual performance by the

Administrative Agent of its obligations to the Lenders under any provision of this Agreement, and Borrower shall have no liability to the Administrative Agent or any of the Lenders in respect of any failure by the Administrative Agent or any Lender to perform any of its obligations to the Administrative Agent or the Lenders under this Agreement. Without limiting the generality of the foregoing, where any provision of this Agreement relating to the payment of any amounts due and owing under the Loan Documents provides that such payments shall be made by Borrower to the Administrative Agent for the account of the Lenders, Borrower’s obligations to the Lenders in respect of such payments shall be deemed to be satisfied upon the making of such payments to the Administrative Agent in the manner provided by this Agreement.

ARTICLE 18

MISCELLANEOUS

     18.1 Cumulative Remedies; No Waiver. The rights, powers, privileges and remedies of the Administrative Agent and the Lenders provided herein or in any Note or other Loan Document are cumulative and not exclusive of any right, power, privilege or remedy provided by Law or equity. No failure or delay on the part of the Administrative Agent or any Lender in exercising any right, power, privilege or remedy may be, or may be deemed to be, a waiver thereof; nor may any single or partial exercise of any right, power, privilege or remedy preclude any other or further exercise of the same or any other right, power, privilege or remedy. The terms and conditions of Articles 6 and 7 hereof are inserted for the sole benefit of the Administrative Agent and the Lenders; the same may be waived in whole or in part, with or without terms or conditions, in respect of any Loan without prejudicing the Administrative Agent’s or the Lenders’ rights to assert them in whole or in part in respect of any other Loan.

     18.2 Subordination of Mortgage to Condominium; Release of BIDMC Parking Unit from Lien of Mortgage.

          (a) Upon the request of the Borrower, Administrative Agent shall (x) subordinate the lien of the Security Documents on the Subject Property to the Condominium Documents and (y) release the BIDMC Parking Unit from such lien on the Subject Property, provided that the following conditions are satisfied: (i) there is then occurring no Event of Default, (ii) the Administrative Agent has reviewed and approved the final form of the Condominium Documents and all plans and other agreements delivered or executed in connection therewith, and determined that such agreements are intended to facilitate the development of the Subject Property and do not have a material and adverse impact on the construction, ownership, use or operation of the Subject Property (and, as of the date hereof, the Administrative Agent hereby approves the current form of the Condominium Documents and all plans and other agreements delivered in connection herewith), (iii) the Administrative Agent has received evidence reasonably satisfactory to the Administrative Agent and the Administrative Agent’s counsel that the Subject Property after such release shall comply with all applicable Laws, including, without limitation, all applicable zoning by-laws and all applicable federal, state, and local permits, (iv) the BIDMC Parking Unit has been assigned a separate tax parcel identification number, or is reasonably anticipated to have a separate tax parcel identification number in the ordinary course, (v) to the extent not previously granted, easements, in

          (b) In order to effectuate the subordination of the lien of the Security Documents on the Subject Property to the Condominium Documents, and the release of the BIDMC Parking Unit from such lien, an escrow arrangement, in form and substance reasonably satisfactory to the Administrative Agent, the Borrower, and BIDMC shall be entered into such that the following events shall all occur: (i) the Administrative Agent, on behalf of the Lenders, shall subordinate such lien to the Condominium Documents, (ii) the Administrative Agent, on behalf of the Lenders, shall release such lien on the BIDMC Parking Unit, (iii) the fee simple determinable currently held by BIDMC in the Adjacent Property shall terminate, and (v) all obligations of the Parking Agreement shall be deemed satisfied such that the Borrower shall receive the purchase price of $28,800,000 (subject to adjustments, and reduced to cover transfer taxes and closing costs per the Parking Agreement) for the BIDMC Parking Unit.

     18.3 Costs, Expenses and Taxes. Borrower shall pay within five (5) Banking Days after demand, accompanied by an invoice therefor, the reasonable costs and expenses of the Administrative Agent in connection with the negotiation, preparation, syndication, execution, delivery, administration and interpretation of the Loan Documents and any amendment thereto or waiver thereof. Following and during the continuation of an Event of Default, Borrower shall also pay on demand, accompanied by an invoice therefor, the reasonable costs and expenses of the Administrative Agent and the Lenders in connection with the refinancing, restructuring, reorganization (including a bankruptcy reorganization) and enforcement or attempted enforcement of the Loan Documents, and any matter related thereto. The foregoing costs and expenses shall include filing fees, recording fees, title insurance fees, appraisal fees, search fees, and other out of pocket expenses and the reasonable fees and out of pocket expenses of any legal counsel (including reasonably allocated costs of legal counsel employed by the Administrative Agent or any Lender), independent public accountants and other outside experts retained by the Administrative Agent or any Lender, whether or not such costs and expenses are incurred or suffered by the Administrative Agent or any Lender in connection with or during the course of any bankruptcy or insolvency proceedings of any member of the Consolidated Group. Borrower shall pay any and all documentary and other taxes, excluding (i) taxes imposed on or measured in whole or in part by any Lender’s overall net income imposed on such Lender (including taxes on gross income imposed in lieu of net income, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which such Lender is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which such Lender is “doing business” or (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which any Lender has failed, for any reason, to provide Borrower with the appropriate form or forms required by Section 18.21, to the extent such forms are then required by applicable Laws to establish a complete exemption, and all

costs, expenses, fees and charges payable or determined to be payable in connection with the filing or recording of this Agreement, any other Loan Document or any other instrument or writing to be delivered hereunder or thereunder, or in connection with any transaction pursuant hereto or thereto, and shall reimburse, hold harmless and indemnify on the terms set forth in Section 18.11 the Administrative Agent and the Lenders from and against any and all loss, liability or legal or other expense with respect to or resulting from any delay in paying or failure to pay any such tax, cost, expense, fee or charge or that any of them may suffer or incur by reason of the failure of any Party to perform any of its Obligations. Any amount payable to the Administrative Agent or any Lender under this Section 18.3 shall bear interest from the fifth Banking Day following the date of demand for payment at the Default Rate.

     18.4 Nature of Lenders’ Obligations. The obligations of the Lenders hereunder are several and not joint or joint and several. Nothing contained in this Agreement or any other Loan Document and no action taken by the Administrative Agent or the Lenders or any of them pursuant hereto or thereto may, or may be deemed to, make the Lenders a partnership, an association, a joint venture or other entity, either among themselves or with Borrower or any other member of the Consolidated Group. A default by any Lender will not increase the Percentage of the Commitments attributable to any other Lender. Any Lender not in default may, if it desires, assume in such proportion as the nondefaulting Lenders agree the obligations of any Lender in default, but is not obligated to do so. The Administrative Agent agrees that it will use reasonable efforts (which will not include the payment of money) either to induce the other Lenders to assume the obligations of a Lender in default or to obtain another Lender, reasonably satisfactory to Borrower, to replace such a Lender in default. A defaulting Lender’s right to participate in the administration of the Loan Documents, including, without limitation, any rights to consent to or direct any action or inaction of the Administrative Agent or to vote on any matter presented to the Lenders shall be suspended during the pendency of such Lender’s default.

     18.5 Survival of Representations and Warranties. All representations and warranties contained herein or in any other Loan Document, or in any certificate or other writing delivered by or on behalf of any one or more of the Parties to any Loan Document, will survive the making of the Loans hereunder and the execution and delivery of the Notes, and have been or will be relied upon by the Administrative Agent and each Lender, notwithstanding any investigation made by the Administrative Agent or any Lender or on their behalf.

     18.6 Notices. Except as otherwise expressly provided in the Loan Documents, all notices, requests, demands, directions and other communications provided for hereunder or under any other Loan Document must be in writing and must be mailed, telegraphed, telecopied, dispatched by commercial courier or delivered to the appropriate party at the address set forth on the signature pages of this Agreement or other applicable Loan Document or, as to any party to any Loan Document, at any other address as may be designated by it in a written notice sent to all other parties to such Loan Document in accordance with this Section. Except as otherwise expressly provided in any Loan Document, if any notice, request, demand, direction or other communication required or permitted by any Loan Document is given by mail it will be effective on the earlier of receipt or the fourth Banking Day after deposit in the United States mail with first class or airmail postage prepaid; if given by telegraph or cable, when delivered to the telegraph company with

charges prepaid; if given by telecopier, when sent; if dispatched by commercial courier, on the scheduled delivery date; or if given by personal delivery, when delivered (provided that if any such communication is received after normal business hours or on a day that is not a Banking Day, it shall be deemed to have been received on the next Banking Day following receipt). The Administrative Agent and the Lenders shall be entitled to rely and act upon any notices purportedly given by or on behalf of Borrower and Lenders shall be entitled to rely and act upon any notices purportedly given to them by or on behalf of the Administrative Agent, even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. Borrower shall indemnify the Administrative Agent and each Lender from all losses, costs, expenses and liabilities resulting from the reliance of such Person on each notice purportedly given by Borrower, except to the extent of such Person’s gross negligence.

     18.7 Execution of Loan Documents. Unless the Administrative Agent otherwise specifies with respect to any Loan Document, (a) this Agreement and any other Loan Document may be executed in any number of counterparts and any party hereto or thereto may execute any counterpart, each of which when executed and delivered will be deemed to be an original and all of which counterparts of this Agreement or any other Loan Document, as the case may be, when taken together will be deemed to be but one and the same instrument and (b) execution of any such counterpart may be evidenced by a telecopier transmission of the signature of such party.

     18.8 Binding Effect; Assignment.

          (a) This Agreement and the other Loan Documents to which the Loan Parties are a party are and will be binding upon and inure to the benefit of the Loan Parties, the Administrative Agent, each of the Lenders, and their respective successors and assigns, except that the Loan Parties may not assign their rights hereunder or thereunder or any interest herein or therein without the prior written consent of all the Lenders, and any purported assignment without such consent shall be null and void. Each Lender represents that it is not acquiring its Note with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (subject to any requirement that disposition of such Note must be within the control of such Lender). Any Lender may at any time pledge or assign a security in all or any portion of its Note or any other instrument evidencing its rights as a Lender under this Agreement to secure obligations of such Lender, including without limitation (i) any pledge or assignment to secure obligations to a Federal Reserve Bank, and (ii) in the case of a Lender that is a Related Fund, any pledge or assignment to any holders of obligations owed, or security issued, by such Lender, including to any trustee for, or any other representative of such holders, provided that no such pledge shall release that Lender from its obligations hereunder or grant to such Federal Reserve Bank or other pledgee or assignee the rights of a Lender hereunder absent foreclosure of such pledge or assignment.

          (b) From time to time following the Closing Date, each Lender may assign to one or more Eligible Assignees all or any portion of its Commitment; provided that (i) such Eligible

- 81 -

Assignee, if not then a Lender or an Affiliate or Related Fund of a Lender, shall require approval by the Administrative Agent and (if no Event of Default then exists) Trust (neither of which approvals shall be unreasonably withheld or delayed), (ii) such assignment shall be evidenced by a Commitments Assignment and Acceptance, a copy of which, together with any Notes subject to such assignment, shall be furnished to the Administrative Agent as hereinbelow provided, (iii) except in the case of an assignment to an Affiliate or Related Fund of the assigning Lender, to another Lender or of the entire remaining Commitment of the assigning Lender, the assignment shall not assign a share of the Commitment that is equivalent to less than $5,000,000, (iv) the assignment shall be of a constant, and not a varying, percentage of the Assignor’s rights and obligations under this Agreement, and (v) the effective date of any such assignment shall be as specified in the Commitments Assignment and Acceptance, but not earlier than the date which is five (5) Banking Days after the date the Administrative Agent has received the Commitments Assignment and Acceptance unless otherwise agreed by the Administrative Agent. Upon the effective date of such Commitments Assignment and Acceptance, the Eligible Assignee named therein shall be a Lender for all purposes of this Agreement, with a Percentage and Commitment amount as therein (and herein, if such Eligible Assignee was already a Lender) set forth and, to the extent of the portion of the Commitment assigned, the assigning Lender shall be released from its further obligations under this Agreement. Borrower agrees that it shall execute and deliver to such assignee Lender, Notes evidencing that assignee Lender’s Commitment, and to the assigning Lender, Notes evidencing the remaining balance of such Lender’s Commitment.

          (c) By executing and delivering a Commitments Assignment and Acceptance, the Eligible Assignee thereunder acknowledges and agrees that: (i) the Administrative Agent has not made any representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness or sufficiency of this Agreement or any other Loan Document; (ii) the Administrative Agent has not made any representation or warranty and assumes no responsibility with respect to the financial condition of the Loan Parties or the performance by the Loan Parties of the Obligations; (iii) it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 15.1 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Commitments Assignment and Acceptance; (iv) it will, independently and without reliance upon the Administrative Agent or any Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) it appoints and authorizes the Administrative Agent to take such action and to exercise such powers under this Agreement as are delegated to the Administrative Agent by this Agreement; and (vi) it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

          (d) The Administrative Agent shall maintain at the Administrative Agent’s Office a copy of each Commitments Assignment and Acceptance delivered to it and a register (the “Register”) of the names and address of each of the Lenders and the Percentage and Commitment amount held by each Lender, giving effect to each Commitments Assignment and Acceptance. The Register shall be available during normal business hours for inspection by Borrower or any Lender

- 82 -

upon reasonable prior notice to the Administrative Agent. After receipt of a completed Commitments Assignment and Acceptance executed by any Lender and an Eligible Assignee and the Notes subject to such assignment, and receipt of an assignment fee of $3,500 from such Lender or Eligible Assignee (which fee shall be imposed only once with respect to simultaneous transfers on a single day to different Affiliates or Related Funds of such Lender), the Administrative Agent shall, promptly following the effective date thereof, upon the request of any party, provide to Borrower and the Lenders a revised Schedule 1.1 giving effect thereto. Borrower, the Administrative Agent and the Lenders shall deem and treat the Persons listed as Lenders in the Register as the holders and owners of the Commitments listed therein for all purposes hereof, and no assignment or transfer of any such Commitment shall be effective, in each case unless and until a Commitments Assignment and Acceptance effecting the assignment or transfer thereof shall have been accepted by the Administrative Agent and recorded in the Register as provided above. Prior to such recordation, all amounts owed with respect to the applicable Commitment shall be owed to the Lender listed in the Register as the owner thereof, and any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a Lender shall be conclusive and binding on any subsequent holder, assignee or transferee of such Commitment.

          (e) Each Lender may from time to time grant participations to one or more banks or other financial institutions (including another Lender but excluding an Employee Plan) in a portion of its Commitment; provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other financial institutions shall not be a Lender hereunder for any purpose except, if the participation agreement so provides, for the purposes of Sections 3.7, 3.8, 18.11 and 18.22 but only to the extent that the cost of such benefits to Borrower does not exceed the cost which Borrower would have incurred absent the participation, (iv) Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, (v) the participation interest shall be expressed as a percentage of the granting Lender’s Commitment as it then exists and shall not afford such participant any rights or privileges under the Loan Documents except as provided in clause (iii) above.

          (f) Notwithstanding anything contained in this Agreement or any other Loan Document to the contrary, Administrative Agent shall have the right to change the structure and terms of the Loan in connection with the syndication of the Loan to the extent and on the terms expressly provided in that certain Mandate Letter dated November 3, 2006 by and among Administrative Agent, KeyBanc Capital Markets, Borrower and Guarantors.

     18.9 Right of Setoff. If an Event of Default has occurred and is continuing, the Administrative Agent or any Lender (but in each case only with the consent of the Requisite Lenders and subject to the provisions of Section 18.10) may exercise its rights under Article 9 of the Uniform Commercial Code and other applicable Laws and, to the extent permitted by applicable Laws, apply any funds in any deposit account maintained with it by Borrower and/or any Property of Borrower in its possession against the Obligations. any and all rights to require administrative agent or any lender to exercise its rights or remedies with respect to

any other collateral which secures the loan (if any), prior to exercising its right of setoff with respect to such deposits, credits, or other property of borrowers, are hereby, knowingly, voluntarily, and irrevocably waived.

     18.10 Sharing of Setoffs. Each Lender severally agrees that if it, through the exercise of any right of setoff, banker’s lien or counterclaim against Borrower, or otherwise, receives payment of the Obligations held by it that is ratably more than any other Lender, through any means, receives in payment of the Obligations held by that Lender, then, subject to applicable Laws: (a) the Lender exercising the right of setoff, banker’s lien or counterclaim or otherwise receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from each of the other Lenders a participation in the Obligations held by the other Lenders and shall pay to the other Lenders a purchase price in an amount so that the share of the Obligations held by each Lender after the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment shall be in the same proportion that existed prior to the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment; and (b) such other adjustments and purchases of participations shall be made from time to time as shall be equitable to ensure that all of the Lenders share any payment obtained in respect of the Obligations ratably in accordance with each Lender’s share of the Obligations immediately prior to, and without taking into account, the payment; provided that, if all or any portion of a disproportionate payment obtained as a result of the exercise of the right of setoff, banker’s lien, counterclaim or otherwise is thereafter recovered from the purchasing Lender by Borrower or any Person claiming through or succeeding to the rights of Borrower, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest (unless the Lender from which such payment is recovered is required to pay interest thereon, in which case each Lender returning funds to such Lender shall pay its pro rata share of such interest). Each Lender that purchases a participation in the Obligations pursuant to this Section 18.10 shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased. Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in an Obligation so purchased pursuant to this Section 18.10 may exercise any and all rights of setoff, banker’s lien or counterclaim with respect to the participation as fully as if the Lender were the original owner of the Obligation purchased.

     18.11 Indemnity by Borrower. Borrower agrees to indemnify, save and hold harmless the Administrative Agent and Lead Arranger and each Lender and their respective directors, officers, agents, attorneys and employees (collectively the “Indemnitees”) from and against: (a) any and all claims, demands, actions or causes of action (except a claim, demand, action, or cause of action for any amount excluded from the definition of “Taxes” in Section 3.9(d)) if the claim, demand, action or cause of action arises out of or relates to any act or omission (or alleged act or omission) of Borrower, the other members of the Consolidated Group or any of their officers, directors or stockholders relating to the Commitments, the use or contemplated use of proceeds of any Loan, or the relationship of Borrower and the Lenders under this Agreement; (b) any administrative or investigative proceeding by any Governmental Agency arising out of or related to a claim, demand, action or cause of action described in clause (a) above; and (c) any and all liabilities, losses, costs or expenses (including reasonable attorneys’ fees and the reasonably allocated costs of attorneys

employed by any Indemnitee and disbursements of such attorneys and other professional services) that any Indemnitee suffers or incurs as a result of the assertion of any foregoing claim, demand, action or cause of action; provided that no Indemnitee shall be entitled to indemnification for any loss caused by its own gross negligence or willful misconduct or for any loss asserted against it by another Indemnitee. If any claim, demand, action or cause of action is asserted against any Indemnitee, such Indemnitee shall promptly notify Borrower, but the failure to so promptly notify Borrower shall not affect Borrower’s obligations under this Section unless such failure materially prejudices Borrower’s right to participate in the contest of such claim, demand, action or cause of action, as hereinafter provided. Such Indemnitee may (and shall, if requested by Borrower in writing) contest the validity, applicability and amount of such claim, demand, action or cause of action and shall permit Borrower to participate in such contest. Any Indemnitee that proposes to settle or compromise any claim or proceeding for which Borrower may be liable for payment of indemnity hereunder shall give Borrower written notice of the terms of such proposed settlement or compromise reasonably in advance of settling or compromising such claim or proceeding and shall obtain Borrower’s prior written consent (which shall not be unreasonably withheld or delayed). In connection with any claim, demand, action or cause of action covered by this Section 18.11 against more than one Indemnitee, all such Indemnitees shall be represented by the same legal counsel (which may be a law firm engaged by the Indemnitees or attorneys employed by an Indemnitee or a combination of the foregoing) selected by the Indemnitees and reasonably acceptable to Borrower; provided, that if such legal counsel determines in good faith that representing all such Indemnitees would or could result in a conflict of interest under Laws or ethical principles applicable to such legal counsel or that a defense or counterclaim is available to an Indemnitee that is not available to all such Indemnitees, then to the extent reasonably necessary to avoid such a conflict of interest or to permit unqualified assertion of such a defense or counterclaim, each affected Indemnitee shall be entitled to separate representation by legal counsel selected by that Indemnitee and reasonably acceptable to Borrower, with all such legal counsel using reasonable efforts to avoid unnecessary duplication of effort by counsel for all Indemnitees; and further provided that the Administrative Agent (as an Indemnitee) shall at all times be entitled to representation by separate legal counsel (which may be a law firm or attorneys employed by the Administrative Agent or a combination of the foregoing). Any obligation or liability of Borrower to any Indemnitee under this Section 18.11 shall survive the expiration or termination of this Agreement and the repayment of all Loans and the payment and performance of all other Obligations owed to the Lenders.

     18.12 Nonliability of the Lenders. Borrower acknowledges and agrees that:

          (a) Any inspections of any Property of Borrower or any other Loan Party made by or through the Administrative Agent or the Lenders are for purposes of administration of the Loan only and Borrower and such other Loan Parties are not entitled to rely upon the same (whether or not such inspections are at the expense of Borrower);

          (b) By accepting or approving anything required to be observed, performed, fulfilled or given to the Administrative Agent or the Lenders pursuant to the Loan Documents, neither the Administrative Agent nor the Lenders shall be deemed to have warranted or represented the sufficiency, legality, effectiveness or legal effect of the same, or of any term, provision or

- 85 -

condition thereof, and such acceptance or approval thereof shall not constitute a warranty or representation to anyone with respect thereto by the Administrative Agent or the Lenders;

          (c) The relationship between Borrower and the Administrative Agent and the Lenders is, and shall at all times remain, solely that of borrowers and lenders; neither the Administrative Agent nor the Lenders shall under any circumstance be construed to be partners or joint venturers of Borrower or any other member of the Consolidated Group, neither the Administrative Agent nor the Lenders shall under any circumstance be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any other member of the Consolidated Group, or to owe any fiduciary duty to Borrower or any other member of the Consolidated Group; neither the Administrative Agent nor the Lenders undertake or assume any responsibility or duty to Borrower or any other member of the Consolidated Group, to select, review, inspect, supervise, pass judgment upon or inform Borrower or any other member of the Consolidated Group, of any matter in connection with their Property or the operations of Borrower or any other member of the Consolidated Group; Borrower and such other members shall rely entirely upon their own judgment with respect to such matters; and any review, inspection, supervision, exercise of judgment or supply of information undertaken or assumed by the Administrative Agent or the Lenders in connection with such matters is solely for the protection of the Administrative Agent and the Lenders and neither Borrower nor any other Person is entitled to rely thereon; and

          (d) The Administrative Agent and the Lenders shall not be responsible or liable to any Person for any loss, damage, liability or claim of any kind relating to injury or death to Persons or damage to Property caused by the actions, inaction or negligence of Borrower and/or any other member of the Consolidated Group, and Borrower hereby indemnifies and holds the Administrative Agent and the Lenders harmless on the terms set forth in Section 18.11 from any such loss, damage, liability or claim.

     18.13 No Third Parties Benefited. This Agreement is made for the purpose of defining and setting forth certain obligations, rights and duties of Borrower, the Administrative Agent and the Lenders in connection with the Loans, and is made for the sole benefit of Borrower, the Administrative Agent and the Lenders, and the Administrative Agent’s and the Lenders’ successors and assigns. Except as provided in Sections 18.8, 18.11 and 18.22 no other Person shall have any rights of any nature hereunder or by reason hereof.

     18.14 Confidentiality.

          (a) Confidentiality. Each Lender and the Administrative Agent (each, a “Lender Party”) hereby agrees for itself only that, except as specifically set forth herein, such Lender Party (i) shall not participate in or generate any press release or other release of information to the general public relating to the closing of the Loan without the prior written consent of Borrower, (ii) shall hold the Confidential Information in strict confidence in accordance with such Lender Party’s customary procedures to prevent the misuse or disclosure of confidential information of this nature and in accordance with safe and sound banking practices, (iii) shall use the Confidential Information solely for the purposes of underwriting the Loan or acquiring an interest therein, carrying out such Lender Party’s rights or obligations under this Agreement, in connection with the syndication of the

- 86 -

Loan, the enforcement of the Loan Documents, or other internal examination, supervision or oversight of the transactions contemplated hereby as reasonably determined by such Lender Party, or as otherwise permitted by the terms of this Section 18.14 (collectively, “Permitted Purposes”), and (iv) shall not disclose the Confidential Information to any third party, except as expressly authorized in this Agreement or with prior written consent of Borrower. Each Lender Party shall promptly notify Borrower in the event that it becomes aware of any loss or unauthorized disclosure of any Confidential Information.

Each Lender Party shall not have any obligations under this Agreement with respect to a specific portion of the Confidential Information if such Lender Party can demonstrate that such Confidential Information (i) was publicly available at the time it was disclosed to such Lender Party, (ii) became publicly available subsequent to the time it was disclosed to such Lender Party (except to the extent such public availability was the result of such Lender Party’s disclosure), (iii) was in or came into a Lender Party’s possession from a source not known to such Lender Party (after reasonable inquiry) to be in breach of an obligation of confidentiality owed to Borrower in making such disclosure to such Lender Party, (iv) was in or comes into Lender Party’s possession free of any obligation of confidence owed to Borrower at the time it was disclosed to such Lender Party, or (v) was developed by the employees or agents of the Lender Party without the use of the Confidential Information.

          (b) Disclosures.

L. 107-56 (signed into law October 26, 2001) (the “Act”), each Lender is required to obtain, verify and record information that identifies the Loan Parties, which information includes the name and address of the Loan Parties and other information that will allow such Lender to identify the Loan Parties in accordance with the Act), (vi) to another potential Lender or participant in connection with an assignment or proposed assignment to that Person of all or part of that Lender Party’s interests hereunder or a participation interest in its Notes, and (vii) to its directors, officers, employees and Affiliates who need to know the Confidential Information for purposes of underwriting the Loan or becoming a party to this Agreement, the syndication of the Loan, the administration, interpretation, performance or exercise of rights under the Loan Documents, the enforcement of the Loan Documents, or other internal supervision, examination or oversight of the transactions contemplated hereby as reasonably determined by such Lender Party, provided that any Person to whom any of the Confidential Information is disclosed is informed by such Lender Party of the strictly confidential nature of the Confidential Information, and such Persons described in clauses (b)(iv) and (vi) shall agree in writing to be bound by confidentiality restrictions at least as restrictive as those contained herein. Notwithstanding the foregoing, a Lender Party may disclose

- 87 -

Confidential Information to the extent such Lender Party is requested or required by any Law or any order of any Governmental Agency or self regulatory body or other legal process to make any disclosure of or about any of the Confidential Information. In such event (except with respect to banking regulators or auditors), such Lender Party shall, if permitted by Law, promptly notify Borrower in writing so that Borrower may seek an appropriate protective order or waive compliance with the provisions of this Agreement (provided that if a protective order or the receipt of a waiver hereunder has not been obtained, or if prior notice is not possible, and a Lender Party is, in the opinion of its counsel, compelled to disclose Confidential Information, such Lender Party may disclose that portion of the Confidential Information which its counsel advises it that such Lender Party is compelled to disclose, and provided further that in any event, such Lender Party will not oppose action by Borrower to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information.) Each Lender Party shall be liable (but only to the extent it is finally determined to have breached the provisions of this Section 18.14(b)) for any actions by such Lender Party (but not any other Person) which are not in accordance with the provisions of this Section 18.14(b).

Notwithstanding anything herein to the contrary, Confidential Information shall not include, and Administrative Agent and each Lender may disclose to any and all Persons, without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011 4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or any Lender relating to such tax treatment and tax structure; provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans, and transactions contemplated hereby.

          (c) No Rights in Confidential Information. The Administrative Agent and each Lender recognizes and agrees that nothing contained in this Section 18.14 shall be construed as granting any property rights, by license or otherwise, to any Confidential Information (other than the Agreement or any amendments thereto or any related agreements), or to any invention or any patent, copyright, trademark, or other intellectual property right that has issued or that may issue, based on such Confidential Information (other than the Agreement or any amendments thereto or any related agreements). No Lender Party shall make, have made, use or sell for any purpose any product or other item using, incorporating or derived from any such Confidential Information; provided that the foregoing shall not limit or restrict in any way the creation, use or sale of banking or related services by any Lender Party.

          (d) Survival. All Confidential Information provided by or on behalf of Borrower during the term of this Agreement or any predecessor agreements shall remain confidential indefinitely and shall continue to receive that level of confidential treatment customarily provided by commercial banks dealing with confidential information of their borrower customers, subject, however, to the specific exceptions to confidential treatment provided herein. For a period of one year after the Termination Date, the affected Lender Party shall continue to make reasonable inquiry of any third party providing Confidential Information as to whether such third party is subject to an

- 88 -

obligation of confidentiality owed to Borrower or its Subsidiaries and if such Lender Party obtains knowledge that such third party is violating a confidentiality agreement with Borrower, such Lender Party shall treat the Confidential Information received from such third party as strictly confidential in accordance with the provisions of this Section 18.14. For purposes of this Section 18.14(d), the “Termination Date” shall mean the earlier of the termination of this Agreement or, with respect to a specific Lender Party, the date such Person no longer holds an interest in the Loan.

          (e) Injunctive Relief. Each Lender Party hereby agrees that breach of this Section 18.14 will cause Borrower irreparable damage for which recovery of damages would be inadequate, and that Borrower shall therefore be entitled to obtain timely injunctive relief under this Agreement, as well as such further relief as may be granted by a court of competent jurisdiction.

          (f) No Fiduciary Duty. Nothing in this Section shall be construed to create or give rise to any fiduciary duty on the part of the Administrative Agent or the Lenders to Borrower.

          (g) Separate Action. Borrower covenants and agrees not to, and hereby expressly waives any right to, raise as a defense, affirmative defense, setoff, recoupment or otherwise against any Lender Party any claim arising from or relating to an alleged breach of this Section 18.14 in any action, claim or proceeding relating to a breach of the Loan Documents by Borrower or other action to enforce or recover the Obligations, and covenant and agree that any claim against a Lender Party arising from or relating to an alleged breach of this Section 18.14 by a Lender Party shall only be asserted as an affirmative claim in a separate action against the applicable Lender Party.

     18.15 Further Assurances. Borrower shall, at its expense and without expense to the Lenders or the Administrative Agent, do, execute and deliver such further acts and documents as the Requisite Lenders or the Administrative Agent from time to time reasonably require for the assuring and confirming unto the Lenders or the Administrative Agent of the rights hereby created or intended now or hereafter so to be, or for carrying out the intention or facilitating the performance of the terms of any Loan Document.

     18.16 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and supersedes all prior agreements, written or oral, on the subject matter hereof. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control and govern; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

     18.17 Governing Law. Except to the extent otherwise provided therein, each Loan Document shall be governed by, and construed and enforced in accordance with, the Laws of the State of New York without any regard to conflicts of law principles that would result in the application of any Law other than the Laws of the State of New York.

     18.18 Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable or invalid as to any party or in any jurisdiction shall, as to that party or jurisdiction, be inoperative, unenforceable or invalid without affecting the remaining provisions or the operation, enforceability or validity of that provision as to any other party or in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

     18.19 Headings. Article and Section headings in this Agreement and the other Loan Documents are included for convenience of reference only and are not part of this Agreement or the other Loan Documents for any other purpose.

     18.20 Time of the Essence. Time is of the essence of the Loan Documents.

     18.21 Delivery of Tax Forms. Each Lender that is incorporated or otherwise organized under the Laws of a jurisdiction other than the United States of America or any State thereof or the District of Columbia shall deliver to Borrower (with a copy to the Administrative Agent), on or before the Closing Date (or on or before accepting an assignment or receiving a participation interest herein pursuant to Section 18.8, if applicable) two duly completed copies, signed by a Responsible Official, of either Form W-8BEN (relating to such Lender and entitling it to a complete exemption from withholding on all payments to be made to such Lender by Borrower pursuant to this Agreement) or Form W-8ECI (relating to all payments to be made to such Lender by Borrower pursuant to this Agreement), or W-8IMY, as applicable, of the United States of America Internal Revenue Service or such other evidence satisfactory to Borrower and the Administrative Agent that no withholding under the federal income tax laws is required with respect to such Lender. If a Lender is claiming a “portfolio interest exemption,” such Lender shall, in addition to Form W-8BEN, provide a certificate signed by a Responsible Official to the effect that (i) such Lender is not a bank within the meaning of Section 881(c)(3)(A) of the Code, (ii) such Lender is not a 10% shareholder of Borrower, and (iii) such Lender is not related to Borrower within the meaning of Section 881(c)(3)(C) of the Code. Thereafter and from time to time, including before the expiration of any previously delivered form, each such Lender shall (a) promptly submit to Borrower (with a copy to the Administrative Agent), such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States of America taxing authorities) as may then be required under then current United States of America Laws and regulations to avoid, or such evidence as is satisfactory to Borrower and the Administrative Agent of any available exemption from, United States of America withholding taxes in respect of all payments to be made to such Lender by Borrower pursuant to this Agreement and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re designation of its LIBOR Lending Office, if any) to avoid any applicable deduction or withholding for taxes from amounts payable to such Lender. In the event that Borrower or the Administrative Agent become aware that a participation has been granted pursuant to Section 18.8(e) to a financial institution that is incorporated or otherwise organized under the Laws of a jurisdiction other than the United States of America, any State thereof or the District of Columbia, then, upon request made by Borrower or the Administrative Agent to the Lender which granted such participation, such Lender shall cause such participant financial institution to deliver the same documents and information to Borrower and the Administrative Agent as would be required under this Section if such financial institution were a

Lender. Each Lender that is a United States of America Person shall, upon the reasonable request of Borrower, deliver Form W-9 on or before the Closing Date (or on or before accepting an assignment or receiving a participation pursuant to Section 18.8, if applicable) and before the expiration of a previously delivered form.

     18.22 [Intentionally Omitted].

     18.23 [Intentionally Omitted].

     18.24 Removal of a Lender. Borrower shall have the right to remove a Lender as a party to this Agreement if (a) such Lender is paid a material amount by Borrower pursuant to Section 3.4 or Section 3.5, (b) any of the events described in Section 16.1(o) occurs with respect to such Lender, or (c) such Lender becomes (and at the time of the proposed removal hereunder remains) a Defaulting Lender hereunder. Upon notice from Borrower, such Lender shall execute and deliver a Commitments Assignment and Acceptance covering that Lender’s Percentage of the Commitments in favor of such Eligible Assignee as Borrower may designate with the approval of the Administrative Agent, subject to payment in full by such Eligible Assignee of all principal, interest and fees and any other amount owing to such Lender through the date of assignment. The removal of any Defaulting Lender pursuant to this Section 18.24 shall not preclude Borrower from pursuing all remedies available to it against such Defaulting Lender for damages arising out of such Defaulting Lender’s breach hereof.

     18.25 Waiver Of Right To Trial By Jury.

     18.27 Sign and Publicity. Borrower shall promptly erect a sign approved in advance by the Administrative Agent and reasonably acceptable to Borrower in a conspicuous location on the

Subject Property during Construction indicating that the financing for the Subject Property is provided by the Lenders. Lenders reserve the right to publicize the making of the Loan.

     18.28 Replacement of Notes. Upon receipt of evidence reasonably satisfactory to Borrower of the loss, theft, destruction or mutilation of any Note, and in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory to Borrower or, in the case of any such mutilation, upon surrender and cancellation of the applicable Note, Borrower will execute and deliver, in lieu thereof, a replacement Note, identical in form and substance to the applicable Note and dated as of the date of the applicable Note and upon such execution and delivery all references in the Loan Documents to such Note shall be deemed to refer to such replacement Note.

     18.29 Defaulting Lenders. In the event that any Lender becomes a Defaulting Lender, then, in addition to any rights and remedies that may be available to Borrower or the other Lenders and the Administrative Agent (such other Lenders and the Administrative Agent being called “Non Defaulting Lenders”) at Law or in equity:

          (a) The Defaulting Lender’s rights to participate in the administration of the Loan and the Loan Documents, including any right to vote upon, approve, disapprove, consent to or direct any action of the Administrative Agent (other than amendments to the Loan Documents directly affecting the Defaulting Lender’s Commitment), shall be suspended and such rights shall not be reinstated unless and until such Lender ceases to be a Defaulting Lender (and all decisions, except the decision to remove the Administrative Agent, which are to be based on a vote of the Requisite Lenders or all Lenders shall be resolved based upon a decision or determination made by the required percentage of the Non-Defaulting Lenders); provided, however, that if the Administrative Agent is a Defaulting Lender, the Administrative Agent shall continue to have all rights provided for in this Loan Agreement, as the Administrative Agent only, with respect to the administration of the Loan unless it is removed and replaced as the Administrative Agent as provided in Section 17.8.

          (b) Any or all of the Non-Defaulting Lenders shall be entitled (but shall not be obligated) to: (i) fund the aggregate amount that the Defaulting Lender has failed to fund or pay to the Administrative Agent (such amount being called the “Defaulted Amount”); and (ii) collect interest at the Default Rate on the Defaulted Amount (after crediting all interest actually paid by Borrower on the Defaulted Amount from time to time), either directly from the Defaulting Lender or from amounts otherwise payable to the Defaulting Lender, for the period from the date on which the Defaulted Amount was funded by the Non-Defaulting Lenders until the date on which payment is made. If the Administrative Agent has funded the Defaulted Amount, the Administrative Agent shall be entitled to collect interest at the Default Rate from the Defaulting Lender on the Defaulted Amount as set forth above, as if the Administrative Agent were a Non-Defaulting Lender that had elected to fund the Defaulted Amount.

          (c) In the event the Defaulted Amount is funded by any Non-Defaulting Lenders or the Administrative Agent pursuant to Section 18.29(b) above, the Defaulting Lender’s interest in the Loans, the Loan Documents and proceeds thereof shall be subordinated to any Defaulted Amount funded by any Non-Defaulting Lenders or the Administrative Agent pursuant to Section

18.29(b) above, plus all interest which may be due in accordance with Section 18.29(b) above (to be applied pari passu among the Non-Defaulting Lenders (including the Administrative Agent, unless the Administrative Agent is the Defaulting Lender) funding the Defaulted Amount), without necessity for executing any further documents; provided that such Defaulting Lender’s interest in the Loan, the Loan Documents and the proceeds thereof shall no longer be so subordinated if the Defaulted Amount funded by the Non-Defaulting Lenders or the Administrative Agent (and all interest which has accrued pursuant to Section 18.29(b) above) shall be repaid in full.

          (d) If, following the payment in full of all amounts due pursuant to Section 18.29(c) above to the Non-Defaulting Lenders (including the Administrative Agent, unless the Administrative Agent is the Defaulting Lender) which have funded all or any portion of any Defaulted Amount, there remains any unfunded Defaulted Amount which has not been funded by the Non-Defaulting Lenders, the Administrative Agent or the Defaulting Lender (“Unfunded Defaulted Amount”), then a portion of the Defaulting Lender’s interest in the Loan, the Loan Documents and the proceeds thereof equal to the amount of the Unfunded Defaulted Amount (together with interest thereon at the rate applicable to the Defaulted Amount from time to time pursuant to the Loan Documents) shall be subordinated to the interests of the Non-Defaulting Lenders (including the Administrative Agent, unless the Administrative Agent is the Defaulting Lender) unless and until such Unfunded Defaulted Amount is funded either by one or more Non -Defaulting Lenders, the Administrative Agent or the Defaulting Lender.

          (e) Subject to the provisions of Section 18.8 and the definition of Eligible Assignee, each Non-Defaulting Lender will have the right, but not the obligation, in its sole discretion, to acquire at par all or a proportionate share (based on the ratio of its Commitment to the aggregate amount of the Commitments of all of the Non-Defaulting Lenders that elect to acquire a share of the Defaulting Lender’s Commitment) of the Defaulting Lender’s Commitment, including without limitation its proportionate share in the outstanding principal balance of the Loan, and all rights and interests of the Defaulting Lender under this Agreement and the other Loan Documents.

          (f) Nothing herein contained shall be deemed or construed to waive, diminish, limit, prevent or estop the Administrative Agent, Borrower or any Lender from exercising or enforcing any rights or remedies which may be available at law or in equity as a result of or in connection with any default under this Agreement by a Lender (including the right to bring suit against the Defaulting Lender to recover the Defaulted Amount and interest thereon at the rate provided in this Section 18.29).

     18.30 Massachusetts Lien Law Provisions. Notwithstanding any other provision in this Agreement or any of the other Loan Documents to the contrary, and in order to comply with the Massachusetts lien law as set forth in Massachusetts General Laws, Chapter 254, it shall not constitute a Default or Event of Default under any of the Loan Documents if a contractor, or any other third party who may be entitled to assert lien rights under Massachusetts General Laws, Chapter 254, Section 2, shall file a notice of contract. However, Lenders shall not be obligated to disburse any proceeds of the Loan which are intended to make any payment to a contractor or any such third party unless and until Administrative Agent shall have received from the applicable contractor or any such third party a properly completed and valid partial waiver and subordination

of lien in a form approved by Administrative Agent and in compliance with Massachusetts General Laws, Chapter 254, Section 2. Further, Lenders shall have the right to not fund a requested Advance if Administrative Agent reasonably believes that the contractor or any such third party may not receive the amounts intended to be advanced to the contractor or any such third party not later than the twenty-fifth (25th) day following the end of the period covered by the applicable partial waiver and subordination of lien. In such event, Administrative Agent may request an updated partial waiver and subordination of lien so that Administrative Agent is reasonably assured that the Advance will be received by the contractor or any such third party not later than 25 days from and after the last day of the period covered by the partial waiver and subordination of lien.

Lenders also shall have the right to defer funding any Advance as to which all or some of the proceeds are intended for payment to a sub-contractor or supplier entitled to file a notice of contract and obtain a lien pursuant to Massachusetts General Laws, Chapter 254, Section 4, if such sub-contractor or supplier has in fact filed a notice of contract under Massachusetts General Laws, Chapter 254, Section 4, unless and until the notice is discharged or bonded in accordance with the applicable provisions of the Massachusetts General Laws, Chapter 254.
