          (d) Unless the Administrative Agent shall have received notice from a Bank prior to the time of any Borrowing that such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in accordance with of this Section 2.5 and the Administrative Agent may, in reliance upon such assumption, but shall not be obligated to, make available to the Borrower on such date a corresponding amount on behalf of such Bank.

Administrative Agent, such Bank agrees to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at the rate of interest applicable to such Borrowing hereunder.

The Administrative Agent shall give prompt notice to the Borrower and the Banks of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of demonstrable error.

          (f) Intentionally Omitted.

          (g) Interest on all Loans (other than Base Rate Loans) shall be payable on the last Business Day of each applicable Interest Period (provided that in the event any Interest Period ends on the date which is 60, 90 or 180 days after the date on which any Interest Period commences, interest on all Loans (other than Base Rate Loans) shall be payable on the first Business Day of each calendar month during such Interest Period and on the last day of such Interest Period) and interest on Base Rate Loans shall be payable on the first Business Day of each calendar month.

          (a) The term (the “Term”) of the Commitments (and each Bank’s obligations to make Loans hereunder) shall terminate and expire on the Maturity Date.

          (b) Upon the date of the termination of the Term, any Loans then outstanding (together with accrued interest thereon and all other Obligations) shall be due and payable on such date.

Any such prepayment shall be upon at least three (3) Business Days notice to the Administrative Agent. Each such optional prepayment shall be in the amounts set forth in Section 2.11(a) above and shall be applied to prepay ratably the Loans of the Banks included in any Group of Euro-Dollar Loans, except that any Euro-Dollar Loan which has been converted to a Base Rate Loan pursuant to Section 8.2, 8.3 or 8.4 hereof may be prepaid without ratable payment of the other Loans in such Group of Loans which have not been so converted.

          (c) Subject to the provisions of Section 2.3, any amounts so prepaid pursuant to Section 2.11(a) or (b) may not be reborrowed.

If and to the extent that the Administrative Agent shall receive any such payment for the account of the Banks on or before 12:00 Noon (Charlotte, North Carolina time) on any Business Day, and Administrative Agent shall not have distributed to any Bank its applicable share of such payment on such Business Day, Administrative Agent shall distribute such amount to such Bank together with interest thereon, for each day from the date such amount should have been distributed to such Bank until the date Administrative Agent distributes such amount to such Bank, at the Federal Funds Rate.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

          In order to induce the Administrative Agent and each of the other Banks which is or may become a party to this Agreement to make the Loans, the Borrower makes the following representations and warranties as of the Closing Date.

          SECTION 4.1. Existence and Power. The Borrower is a limited partnership, duly formed and validly existing as a limited partnership under the laws of the State of Delaware and has all powers and all material governmental licenses, authorizations, consents and approvals required to own its property and assets and carry on its business as now conducted or as it presently proposes to conduct and has been duly qualified and is in good standing in every jurisdiction in which the failure to be so qualified and/or in good standing is likely to have a Material Adverse Effect. EOPT is a real estate investment trust, duly formed, validly existing and in good standing as a real estate investment trust under the laws of the State of Maryland and has all powers and all material governmental licenses, authorizations, consents and approvals required to own its property and assets and carry on its business as now conducted or as it presently proposes to conduct and has been duly qualified and is in good standing in every jurisdiction in which the failure to be so qualified and/or in good standing is likely to have a Material Adverse Effect.

          SECTION 4.2. Power and Authority. The Borrower has the partnership power and authority to execute, deliver and carry out the terms and provisions of each of the Loan Documents to which it is a party and has taken all necessary partnership action, if any, to authorize the execution and delivery on behalf of the Borrower and the performance by the Borrower of such Loan Documents. The Borrower and EOPT each have duly executed and delivered each Loan Document to which it is a party in accordance with the terms of this Agreement, and each such Loan Document constitutes the legal, valid and binding obligation of the Borrower and EOPT, enforceable in accordance with its terms, except as enforceability may be limited by applicable insolvency, bankruptcy or other laws affecting creditors rights generally, or general principles of equity, whether such enforceability is considered in a proceeding in equity or at law. EOPT has the power and authority to execute, deliver and carry out the terms and provisions of each of the Loan Documents to which it is a party and has taken all necessary action to authorize the execution, delivery and performance of such Loan Documents. EOPT has the power and authority to execute, deliver and carry out the terms and provisions of each of the Loan Documents on behalf of the Borrower to which the Borrower is a party and has taken all necessary action to authorize the execution and delivery on behalf of the Borrower and the performance by the Borrower of such Loan Documents.

          SECTION 4.3. No Violation.

          (a) Neither the execution, delivery or performance by or on behalf of the Borrower of the Loan Documents to which it is a party, nor compliance by the Borrower with the terms and provisions thereof nor the consummation of the transactions contemplated by the Loan Documents, (i) will materially contravene any applicable provision of any law, statute, rule, regulation, order, writ, injunction or decree of any court or governmental instrumentality, (ii) will materially conflict with or result in any breach of, any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of the Borrower or any of its Consolidated Subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, or other agreement or other instrument to which the

Borrower (or of any partnership of which the Borrower is a partner) or any of its Consolidated Subsidiaries is a party or by which it or any of its property or assets is bound or to which it is subject (except for such breaches and defaults under loan agreements which the lenders thereunder have agreed to forbear pursuant to valid forbearance agreements), or (iii) will cause a material default by the Borrower under any organizational document of any Person in which the Borrower has an interest, or cause a material default under the Borrower’s agreement or certificate of limited partnership, the consequences of which conflict, breach or default would have a Material Adverse Effect, or result in or require the creation or imposition of any Lien whatsoever upon any Property (except as contemplated herein).

          (b) Neither the execution, delivery or performance by EOPT of the Loan Documents to which it is a party, nor compliance by EOPT with the terms and provisions thereof nor the consummation of the transactions contemplated by the Loan Documents, (i) will materially contravene any applicable provision of any law, statute, rule, regulation, order, writ, injunction or decree of any court or governmental instrumentality, (ii) will materially conflict with or result in any breach of, any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of EOPT or any of its Consolidated Subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, or other agreement or other instrument to which EOPT (or of any partnership of which EOPT is a partner) or any of its Consolidated Subsidiaries is a party or by which it or any of its property or assets is bound or to which it is subject (except for such breaches and defaults under loan agreements which the lenders thereunder have agreed to forbear pursuant to valid forbearance agreements), or (iii) will cause a material default by EOPT under any organizational document of any Person in which EOPT has an interest, the consequences of which conflict, breach or default would have a Material Adverse Effect, or result in or require the creation or imposition of any Lien whatsoever upon any Property (except as contemplated herein).

          SECTION 4.4. Financial Information.

          (a) The consolidated balance sheets of EOPT and the Borrower as of December 31, 2004, and the related statements of operations and cash flows of EOPT and the Borrower for the fiscal year then ended, reported on by Ernst & Young LLP, fairly present, in conformity with GAAP, the consolidated financial position of EOPT and the Borrower, as the case may be, as of such date and the consolidated results of operations and cash flows for such fiscal year.

          (b) Since June 30, 2005, (i) except as may have been disclosed in writing to the Banks, nothing has occurred prior to the Closing Date having a Material Adverse Effect, and (ii) except as set forth on Schedule 4.4(b), neither the Borrower nor EOPT has incurred any material indebtedness or guaranty on or before the Closing Date.

          SECTION 4.5. Litigation. Except as previously disclosed by the Borrower in writing to the Banks, there is no action, suit, proceeding or investigation pending against, or to the knowledge of the Borrower threatened against or affecting, (i) the Borrower, EOPT or any of their Consolidated Subsidiaries, (ii) the Loan Documents or any of the transactions contemplated by the Loan Documents or (iii) any of their assets, before any court or arbitrator or any governmental body, agency or official in which there is a reasonable possibility of an adverse decision which could, individually, or in the aggregate have a Material Adverse Effect or which in any manner draws into question the validity of this Agreement or the other Loan Documents. As of the Closing Date, no such action, suit or proceeding exists.

          SECTION 4.6. Compliance with ERISA. Except for a “prohibited transaction” arising solely because of a Bank’s breach of the covenant set forth in Section 9.17 hereof, the transactions contemplated by the Loan Documents will not constitute a nonexempt prohibited transaction (as such term is defined in Section 4975 of the Code or Section 406 of ERISA) that could subject the Administrative Agent or any of the Banks to any tax or penalty on prohibited transactions imposed under Section 4975 of the Code or Section 502(i) of ERISA and such transactions will not otherwise result in the Administrative Agent or any of the Banks being deemed in violation of Sections 404 or 406 of ERISA or Section 4975 of the Code or in the Administrative Agent or any of the Banks being a fiduciary or party in interest under ERISA or a “disqualified person” as defined in Section 4975(e)(2) of the Code with respect to an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code. No assets of Borrower constitute “assets” (within the meaning of ERISA or Section 4975 of the Code, including, but not limited to, 29 C.F.R. § 2510.3-101 or any successor regulation thereto) of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code. In addition to the prohibitions set forth in this Agreement and the other Loan Documents, and not in limitation thereof, Borrower covenants and agrees that Borrower shall not use any “assets” (within the meaning of ERISA or Section 4975 of the Code, including but not limited to 29 C.F.R. § 2510.3-101) of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code to repay or secure the Note, the Loan, or the Obligations.

          SECTION 4.7. Environmental. The Borrower conducts reviews of the effect of Environmental Laws on the business, operations and properties of the Borrower and its Consolidated Subsidiaries when necessary in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, and any actual or potential liabilities to third parties, including, without limitation, employees, and any related costs and expenses). On the basis of this review, the Borrower has reasonably concluded that such associated liabilities and costs, including, without limitation, the costs of compliance with Environmental Laws, are unlikely to have a Material Adverse Effect.

          SECTION 4.8. Taxes. The Borrower, EOPT and their Consolidated Subsidiaries have filed all United States Federal income tax returns and all other material tax returns which are required to be filed by them and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Borrower, EOPT or any Consolidated Subsidiary, except such taxes, if any, as are reserved against in accordance with GAAP, such taxes as are being contested in good faith by appropriate proceedings or such taxes, the failure to make payment of which when due and payable will not have, in the aggregate, a Material Adverse Effect. The charges, accruals and reserves on the books of the Borrower, EOPT and their Consolidated Subsidiaries in respect of taxes or other governmental charges are, in the opinion of the Borrower, adequate.

          SECTION 4.9. Full Disclosure. All information heretofore furnished by the Borrower to the Administrative Agent or any Bank for purposes of or in connection with this Agreement or any transaction contemplated hereby or thereby is true and accurate in all material respects on the date as of which such information is stated or certified. The Borrower has disclosed to the Administrative Agent, in writing any and all facts which have or may have (to the extent the Borrower can now reasonably foresee) a Material Adverse Effect.

          SECTION 4.11. Use of Proceeds. All proceeds of the Loans will be used by the Borrower only in accordance with the provisions hereof. Neither the making of any Loan nor the use of the proceeds thereof will violate or be inconsistent with the provisions of regulations T, U, or X of the Federal Reserve Board.

          SECTION 4.12. Governmental Approvals. No order, consent, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, any Governmental Authority, or any subdivision thereof, is required to authorize, or is required in connection with the execution, delivery and performance of any Loan Document or the consummation of any of the transactions contemplated thereby other than those that have already been duly made or obtained and remain in full force and effect or those which, if not made or obtained, would not have a Material Adverse Effect;

          SECTION 4.13. Investment Company Act; Public Utility Holding Company Act. Neither the Borrower, EOPT nor any Consolidated Subsidiary is (x) an “investment company” or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended, (y) a “holding company” or a “subsidiary company” of a “holding company” or an “affiliate” of either a “holding company” or a “subsidiary company” within the meaning of the Public Utility Holding Company Act of 1935, as amended, or (z) subject to any other federal or state law or regulation which purports to restrict or regulate its ability to borrow money.

          SECTION 4.14. Principal Offices. As of the Closing Date, the principal office, chief executive office and principal place of business of the Borrower is ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇.

          SECTION 4.15. REIT Status. EOPT is qualified and EOPT intends to continue to qualify as a real estate investment trust under the Code.

          SECTION 4.16. Patents, Trademarks, etc. The Borrower has obtained and holds in full force and effect all patents, trademarks, servicemarks, trade names, copyrights and other such rights, free from burdensome restrictions, which are necessary for the operation of its business as presently conducted, the impairment of which is likely to have a Material Adverse Effect.

          SECTION 4.17. Judgments. There are no final, non-appealable judgments or decrees in an aggregate amount of Five Million Dollars ($5,000,000) or more entered by a court or courts of competent jurisdiction against EOPT or the Borrower or, to the extent such judgment would be recourse to EOPT or Borrower, any of its Consolidated Subsidiaries (other than judgments as to which, and only to the extent, a reputable insurance company has acknowledged coverage of such claim in writing or which have been paid or stayed).

          SECTION 4.18. No Default. No Event of Default or, to the best of the Borrower’s knowledge, Default exists under or with respect to any Loan Document and neither the Borrower nor EOPT is in default in any material respect beyond any applicable grace period under or with respect to any other material agreement, instrument or undertaking to which it is a party or by which it or any of its property is bound in any respect, the existence of which default is likely to result in a Material Adverse Effect.

          SECTION 4.19. Licenses, etc. The Borrower has obtained and does hold in full force and effect, all franchises, licenses, permits, certificates, authorizations, qualifications, accreditation, easements, rights of way and other consents and approvals which are necessary for the operation of its businesses as presently conducted, the absence of which is likely to have a Material Adverse Effect.

          SECTION 4.20. Compliance With Law. To the Borrower’s knowledge, the Borrower and each of its Real Property Assets are in compliance with all laws, rules, regulations, orders, judgments, writs and decrees, including, without limitation, all building and zoning ordinances and codes, the failure to comply with which is likely to have a Material Adverse Effect.

          SECTION 4.21. No Burdensome Restrictions. Except as may have been disclosed by the Borrower in writing to the Banks, Borrower is not a party to any agreement or instrument or subject to any other obligation or any charter or corporate or partnership restriction, as the case may be, which, individually or in the aggregate, is likely to have a Material Adverse Effect.

The Borrower has not dealt with any broker or finder with respect to the transactions contemplated by this Agreement or otherwise in connection with this Agreement, and the Borrower has not done any act, had any negotiations or conversation, or made any agreements or promises which will in any way create or give rise to any obligation or liability for the payment by the Borrower of any brokerage fee, charge, commission or other compensation to any party with respect to the transactions contemplated by the Loan Documents, other than the fees payable to the Administrative Agent, the Lead Arrangers and the Banks, and certain other Persons as previously disclosed in writing to the Administrative Agent.

          SECTION 4.23. Intentionally Omitted.

          SECTION 4.24. Intentionally Omitted.

          SECTION 5.3. Maintenance of Property; Insurance; Leases.

          (a) The Borrower will keep, and will cause each Consolidated Subsidiary to keep, all property useful and necessary in its business, including without limitation its Real Property Assets (for so long as it constitutes Real Property Assets), in good repair, working order and condition, ordinary wear and tear excepted, in each case where the failure to so maintain and repair will have a Material Adverse Effect.

          (b) The Borrower shall maintain, or cause to be maintained, insurance at 100% replacement cost insurance coverage (subject to customary deductibles) in respect of each of its Real Property Assets, as well as commercial general liability insurance (including, without limitation, “builders’ risk” where applicable) against claims for personal, and bodily injury and/or death, to one or more persons, or property damage, as well as workers’ compensation insurance, in each case with respect to liability and casualty insurance with insurers having an A.M.

so will not have a Material Adverse Effect or expose Administrative Agent or Banks to any material liability therefor.

          SECTION 5.6. Inspection of Property, Books and Records. The Borrower will keep proper books of record and account in which full, true and correct entries shall be made of all dealings and transactions in relation to its business and activities in conformity with GAAP, modified as required by this Agreement and applicable law; and will permit representatives of any Bank at such Bank’s expense to visit and inspect any of its properties, including without limitation its Real Property Assets, and so long as disclosure of such information could not result in a violation of, or expose the Borrower, EOPT or their Subsidiaries to any material liability under, any applicable law, ordinance or regulation or any agreements with unaffiliated third parties that are binding on the Borrower, EOPT or any of their Subsidiaries or on any Property of any of them, to examine and make abstracts from any of its books and records and to discuss its affairs, finances and accounts with its officers and independent public accountants, all at such reasonable times during normal business hours, upon reasonable prior notice and as often as may reasonably be desired.

          SECTION 7.5. Liability of Administrative Agent. As between Administrative Agent on the one hand and the Banks on the other hand, none of the Administrative Agent nor any of its affiliates nor any Agent-Related Person, shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Majority Banks or (ii) in the absence of its own gross negligence or willful misconduct. As between Administrative Agent on the one hand and the Banks on the other hand, none of the Administrative Agent nor any Agent-Related Person, shall be responsible for or have any duty to ascertain, inquire into or verify: (i) any statement, warranty or representation made in connection with this Agreement or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower; (iii) the satisfaction of any condition specified in Article III, except receipt of items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness or genuineness of this Agreement, the other Loan Documents or any other instrument or writing furnished in connection herewith.

          SECTION 7.6. Indemnification. Each Bank shall, ratably in accordance with its Commitment, indemnify the Administrative Agent and each Agent-Related Person and their affiliates and its directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including, without limitation, counsel fees and disbursements), claim, demand, action,

loss or liability (except such as result from such indemnitee’s gross negligence or willful misconduct) that such indemnitee may suffer or incur in connection with its duties as Administrative Agent under this Agreement, the other Loan Documents or any action taken or omitted by such indemnitee hereunder. In the event that the Administrative Agent or any Agent-Related Person shall, subsequent to its receipt of indemnification payment(s) from Banks in accordance with this section, recoup any amount from the Borrower, or any other party liable therefor in connection with such indemnification, the Administrative Agent or such Agent-Related Person shall reimburse the Banks which previously made the payment(s) pro rata, based upon the actual amounts which were theretofore paid by each Bank. The Administrative Agent or such Agent-Related Person shall reimburse such Banks so entitled to reimbursement within two (2) Business Days of its receipt of such funds from the Borrower or such other party liable therefor.

          SECTION 7.7. Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent, the Syndication Agent or any other Bank or Agent-Related Person, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

          SECTION 7.8. Successor Administrative Agent or Syndication Agent. The Administrative Agent or the Syndication Agent may resign at any time by giving notice thereof to the Banks, the Borrower and each other. In addition, the Administrative Agent shall resign in the event its Commitment (without participations) is reduced to less than Thirty Million Dollars ($30,000,000), unless as a result of a cancellation or reduction in the aggregate Commitments. Upon any such resignation, the Majority Banks shall have the right to appoint a successor Administrative Agent or Syndication Agent, as applicable, which successor Administrative Agent or successor Syndication Agent (as applicable) shall, provided no Event of Default has occurred and is then continuing, be subject to Borrower’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. If no successor Administrative Agent or Syndication Agent (as applicable) shall have been so appointed by the Majority Banks and approved by the Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent or Syndication Agent (as applicable) gives notice of resignation, then the retiring Administrative Agent, or retiring Syndication Agent (as applicable) may, on behalf of the Banks, appoint a successor Administrative Agent or Syndication Agent (as applicable), which shall be the Administrative Agent or the Syndication Agent as the case may be, who shall act until the Majority Banks shall appoint an Administrative Agent or Syndication Agent. Any appointment of a successor Administrative Agent or Syndication Agent by Majority Banks or the retiring Administrative Agent or the Syndication Agent pursuant to the preceding sentence shall, provided no Event of Default has occurred and is then continuing, be subject to the Borrower’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Upon the

acceptance of its appointment as the Administrative Agent or Syndication Agent hereunder by a successor Administrative Agent or successor Syndication Agent, as applicable, such successor Administrative Agent, or successor Syndication Agent, as applicable, shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent or retiring Syndication Agent, as applicable, and the retiring Administrative Agent or the retiring Syndication Agent, as applicable, shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent’s or retiring Syndication Agent’s resignation hereunder, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent or the Syndication Agent, as applicable. For gross negligence or willful misconduct, as determined by all the Banks (excluding for such determination Administrative Agent in its capacity as a Bank, as applicable), Administrative Agent or Syndication Agent may be removed at any time by giving at least thirty (30) Business Days prior written notice to Administrative Agent, Syndication Agent and Borrower. Such resignation or removal shall take effect upon the acceptance of appointment by a successor Administrative Agent or Syndication Agent, as applicable, in accordance with the provisions of this Section 7.8.

     SECTION 7.9. Consents and Approvals. All communications from Administrative Agent to the Banks requesting the Banks’ determination, consent, approval or disapproval (i) shall be given in the form of a written notice to each Bank, (ii) shall be accompanied by a description of the matter or item as to which such determination, approval, consent or disapproval is requested, or shall advise each Bank where such matter or item may be inspected, or shall otherwise describe the matter or issue to be resolved, (iii) shall include, if reasonably requested by a Bank and to the extent not previously provided to such Bank, written materials and a summary of all oral information provided to Administrative Agent by Borrower in respect of the matter or issue to be resolved, and (iv) shall include Administrative Agent’s recommended course of action or determination in respect thereof. Each Bank shall reply promptly, but in any event within ten (10) Business Days after receipt of the request therefor from Administrative Agent (the “Bank Reply Period”). Unless a Bank shall give written notice to Administrative Agent that it objects to the recommendation or determination of Administrative Agent (together with a written explanation of the reasons behind such objection) within the Bank Reply Period, such Bank shall be deemed to have approved of or consented to such recommendation or determination. With respect to decisions requiring the approval of the Majority Banks or all the Banks, Administrative Agent shall submit its recommendation or determination for approval of or consent to such recommendation or determination to all Banks and upon receiving the required approval or consent shall follow the course of action or determination of the Majority Banks or all the Banks (and each non-responding Bank shall be deemed to have concurred with such recommended course of action), as the case may be.

ARTICLE VIII

CHANGE IN CIRCUMSTANCES

          SECTION 8.1. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar Borrowing the Administrative Agent determines in good faith that deposits in dollars (in the applicable amounts) are not being offered in the relevant market for such Interest Period, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make Euro-Dollar Loans shall be suspended. Unless the Borrower notifies the Administrative Agent at least two Business Days before the date of any Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing.

          SECTION 8.2. Illegality. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency shall make it unlawful for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower, whereupon until such Bank notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank in case of the event described above to make Euro-Dollar Loans, shall be suspended. With respect to Euro-Dollar Loans, before giving any notice to the Administrative Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans to maturity and shall so specify in such notice, the Borrower shall be deemed to have delivered a Notice of Interest Rate Election and such Euro-Dollar Loan shall be converted as of such date to a Base Rate Loan (without payment of any amounts that Borrower would otherwise be obligated to pay pursuant to Section 2.13 hereof with respect to Loans converted pursuant to this Section 8.2) in an equal principal amount from such Bank (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and such Bank shall make such a Base Rate Loan.

          If at any time, it shall be unlawful for any Bank to make, maintain or fund its Euro-Dollar Loans, the Borrower shall have the right, upon five (5) Business Day’s notice to the Administrative Agent, to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to

offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans, and to become a Bank hereunder, or obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest and all other amounts due thereon, upon which event, such Bank’s Commitments shall be deemed to be canceled pursuant to Section 2.11(e).

          SECTION 8.3. Increased Cost and Reduced Return.

          (a) If, on or after the date hereof in the case of Loans made pursuant to Section 2.1, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) made at the Closing Date of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or on the interbank market any other condition materially more burdensome in nature, extent or consequence than those in existence as of the Loan Effective Date affecting such Bank’s Euro-Dollar Loans, its Note, or its obligation to make Euro-Dollar Loans, and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect to such Euro-Dollar Loans, by an amount deemed by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts (based upon a reasonable allocation thereof by such Bank to the Euro-Dollar Loans made by such Bank hereunder) as will compensate such Bank for such increased cost or reduction to the extent such Bank generally imposes such additional amounts on other borrowers of such Bank in similar circumstances.

          (b) If any Bank shall have reasonably determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but for such adoption, change, request or directive (taking into consideration its

policies with respect to capital adequacy) by an amount reasonably deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction to the extent such Bank generally imposes such additional amounts on other borrowers of such Bank in similar circumstances.

          (c) Each Bank will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall fail to notify Borrower of any such event within 90 days following the end of the month during which such event occurred, then Borrower’s liability for any amounts described in this Section incurred by such Bank as a result of such event shall be limited to those attributable to the period occurring subsequent to the ninetieth (90th) day prior to the date upon which such Bank actually notified Borrower of the occurrence of such event. A certificate of any Bank claiming compensation under this Section and setting forth a reasonably detailed calculation of the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of demonstrable error. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

          (d) If at any time, any Bank shall be owed amounts pursuant to this Section 8.3, the Borrower shall have the right, upon five (5) Business Day’s notice to the Administrative Agent to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans, and to become a Bank hereunder, or to obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest and all other amounts due thereon, upon which event, such Bank’s Commitment shall be deemed to be canceled pursuant to Section 2.11(e).

          SECTION 8.4. Taxes.

          (a) Any and all payments by the Borrower to or for the account of any Bank or the Administrative Agent hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Bank or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise or similar taxes imposed on it, by the jurisdiction of such Bank’s Applicable Lending Office or any political subdivision thereof or by any other jurisdiction (or any political

subdivision thereof) as a result of a present or former connection between such Bank or Administrative Agent and such other jurisdiction or by the United States (all such non-excluded taxes, duties, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Non-Excluded Taxes”). If the Borrower shall be required by law to deduct any Non-Excluded Taxes from or in respect of any sum payable hereunder or under any Note, (i) the sum payable shall be increased as necessary so that after making all required deductions (including, without limitation, deductions applicable to additional sums payable under this Section 8.4) such Bank or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.1, the original or a certified copy of a receipt evidencing payment thereof.

          (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, or charges or similar levies which arise from any payment made hereunder or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note (hereinafter referred to as “Other Taxes”).

          (c) In the event that Non-Excluded Taxes not imposed on the Closing Date are imposed, or Non-Excluded Taxes imposed on the Closing Date increase, the applicable Bank shall notify the Administrative Agent and the Borrower of such event in writing within a reasonable period following receipt of knowledge thereof. If such Bank shall fail to notify Borrower of any such event within ninety (90) days following the end of the month during which such event occurred, then Borrower’s liability for such additional Non-Excluded Taxes incurred by such Bank as a result of such event (including payment of a make-whole amount under Section 8.4(a)(i)) shall be limited to those attributable to the period occurring subsequent to the ninetieth (90th) day prior to, but excluding, the date upon which such Bank actually notified Borrower of the occurrence of such event.

          (d) The Borrower agrees to indemnify each Bank and the Administrative Agent for the full amount of Non-Excluded Taxes or Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 8.4) paid by such Bank or the Administrative Agent (as the case may be) and, so long as such Bank or Administrative Agent has promptly paid any such Non-Excluded Taxes or Other Taxes, any liability for penalties and interest arising therefrom or with respect thereto. This indemnification shall be made within 15 days from the date such Bank or the Administrative Agent (as the case may be) makes demand therefor.

          (e) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, shall provide the Borrower with (A) two duly completed copies of Internal Revenue

Service form 1001, or any successor form prescribed by the Internal Revenue Service, and (B) an Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the Internal Revenue Service, and shall provide Borrower with two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to Borrower, certifying (i) in the case of a Form 1001, that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, and (ii) in the case of being under Sections 1442(c)(1) and 1442(a) of the Internal Revenue Code, that it is entitled to an exemption from United States backup withholding tax. If the form provided by a Bank at the time such Bank first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from “Non-Excluded Taxes” as defined in Section 8.4(a).

          (f) For any period with respect to which a Bank has failed to provide the Borrower with the appropriate form pursuant to Section 8.4(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 8.4(c) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes so long as Borrower shall incur no cost or liability as a result thereof.

          (g) Upon reasonable demand by Borrower to the Administrative Agent or any Bank, the Administrative Agent or Bank, as the case may be, shall deliver to the Borrower, or to such government or taxing authority as the Borrower may reasonably direct, any form or document that may be required or reasonably requested in writing in order to allow the Borrower to make a payment to or for the account of such Bank or the Administrative Agent hereunder or under any other Loan Document without any deduction or withholding for or on account of any Non-Excluded Taxes or with such deduction or withholding at a reduced rate (so long as the completion, execution or submission of such form or document would not materially prejudice the legal or commercial position of the party in receipt of such demand), with any such form or document to be accurate and completed in a manner reasonably satisfactory to the Borrower making such demand and to be executed and to be delivered with any reasonably required certification.

          (h) If the Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 8.4, then such Bank will change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

          (i) If at any time, any Bank shall be owed amounts pursuant to this Section 8.4, the Borrower shall have the right, upon five (5) Business Day’s notice to the Administrative Agent to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans, and to become a Bank hereunder, or to obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest and all other amounts due thereon, upon which event, such Bank’s Commitment shall be deemed to be canceled pursuant to Section 2.11(c).

          SECTION 8.5. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.2 or (ii) any Bank has demanded compensation under Section 8.3 or 8.4 with respect to its Euro-Dollar Loans and the Borrower shall, by at least five Business Days’ prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist:

          (a) Borrower shall be deemed to have delivered a Notice of Interest Rate Election with respect to such affected Euro-Dollar Loans and thereafter all Loans which would otherwise be made by such Bank as Euro-Dollar Loans shall be made instead as Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and

          (b) after each of its Euro-Dollar Loans has been repaid, all payments of principal which would otherwise be applied to repay such Euro-Dollar Loans shall be applied to repay its Base Rate Loans instead, and

          (c) Borrower will not be required to make any payment which would otherwise be required by Section 2.13 with respect to such Euro-Dollar Loans converted to Base Rate Loans pursuant to clause (a) above.

          SECTION 9.3. Expenses; Indemnification.

          (a) The Borrower shall pay within thirty (30) days after written notice from the Administrative Agent, (i) all reasonable out-of-pocket costs and expenses of the Administrative Agent (including, without limitation, reasonable fees and disbursements of special counsel Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP), in connection with the preparation of this Agreement, the Loan Documents and the documents and instruments referred to therein, and any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder, (ii) all reasonable fees and disbursements of special counsel in connection with the syndication of the Loans, and (iii) if an Event of Default occurs, all reasonable out-of-pocket expenses incurred by the Administrative Agent and each Bank, including, without limitation, fees and disbursements of counsel for the Administrative Agent and each of the Banks, in connection with the enforcement of the Loan Documents and the instruments referred to therein and such Event of Default and collection, bankruptcy, insolvency and other enforcement proceedings resulting therefrom; provided, however, that the attorneys’ fees and disbursements for which Borrower is obligated under this subsection (a)(iii) shall be limited to the reasonable non-duplicative fees and disbursements of (A) counsel for Administrative Agent, and (B) counsel for all of the Banks as a group; and provided, further, that all other costs and expenses for which Borrower is obligated under this subsection (a)(iii) shall be limited to the reasonable non-duplicative costs and expenses of Administrative Agent. For purposes of this Section 9.3(a)(iii), (1)

counsel for Administrative Agent shall mean a single outside law firm representing Administrative Agent, and (2) counsel for all of the Banks as a group shall mean a single outside law firm representing such Banks as a group (which law firm may or may not be the same law firm representing Administrative Agent).

          (b) The Borrower agrees to indemnify the Administrative Agent and each Bank, their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding that may at any time (including, without limitation, at any time following the payment of the Obligations) be asserted against any Indemnitee, as a result of, or arising out of, or in any way related to or by reason of, (i) any of the transactions contemplated by the Loan Documents or the execution, delivery or performance of any Loan Document, (ii) any violation by the Borrower or the Environmental Affiliates of any applicable Environmental Law, (iii) any Environmental Claim arising out of the management, use, control, ownership or operation of property or assets by the Borrower or any of the Environmental Affiliates, including, without limitation, all on-site and off-site activities of Borrower or any Environmental Affiliate involving Materials of Environmental Concern, (iv) the breach of any environmental representation or warranty set forth herein, but excluding those liabilities, losses, damages, costs and expenses (a) for which such Indemnitee has been compensated pursuant to the terms of this Agreement, (b) incurred solely by reason of the gross negligence, willful misconduct bad faith or fraud of any Indemnitee as finally determined by a court of competent jurisdiction, (c) arising from violations of Environmental Laws relating to a Property which are caused by the act or omission of such Indemnitee after such Indemnitee takes possession of such Property or (d) owing by such Indemnitee to any third party based upon contractual obligations of such Indemnitee owing to such third party which are not expressly set forth in the Loan Documents. In addition, the indemnification set forth in this Section 9.3(b) in favor of any director, officer, agent or employee of Administrative Agent or any Bank shall be solely in their respective capacities as such director, officer, agent or employee. The Borrower’s obligations under this Section shall survive the termination of this Agreement and the payment of the Obligations. Without limitation of the other provisions of this Section 9.3, Borrower shall indemnify and hold each of the Administrative Agent and the Banks free and harmless from and against all loss, costs (including reasonable attorneys’ fees and expenses), expenses, taxes, and damages (including consequential damages) that the Administrative Agent and the Banks may suffer or incur by reason of the investigation, defense and settlement of claims and in obtaining any prohibited transaction exemption under ERISA or the Code necessary in the Administrative Agent’s reasonable judgment by reason of the inaccuracy of the representations and warranties, or a breach of the provisions, set forth in Section 4.6(b).

          SECTION 9.4. Sharing of Set-Offs. In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default, each Bank is hereby authorized at any time or from

time to time, without presentment, demand, protest or other notice of any kind to the Borrower or to any other Person, any such notice being hereby expressly waived, but subject to the prior consent of the Administrative Agent to set off and to appropriate and apply any and all deposits (general or special, time or demand, provisional or final) and any other indebtedness at any time held or owing by such Bank (including, without limitation, by branches and agencies of such Bank wherever located) to or for the credit or the account of the Borrower against and on account of the Obligations of the Borrower then due and payable to such Bank under this Agreement or under any of the other Loan Documents, including, without limitation, all interests in Obligations purchased by such Bank. Each Bank agrees that if it shall by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it, which is greater than the proportion received by any other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have to any deposits not received in connection with the Loans and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness under the Notes. The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. Notwithstanding anything to the contrary contained herein, any Bank may, by separate agreement with the Borrower, waive its right to set off contained herein or granted by law and any such written waiver shall be effective against such Bank under this Section 9.4.

          SECTION 9.5. Amendments and Waivers. Any provision of this Agreement or the Notes or other Loan Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Majority Banks (and, if the rights or duties of the Administrative Agent in its capacity as Administrative Agent are affected thereby, by the Administrative Agent); provided that (A) no amendment or waiver of the provisions of Article V (including, without limitation, any of the definitions of the defined terms used in Section 5.8 hereof) shall be effective unless signed by the Borrower and the Majority Banks and (B) no such amendment or waiver with respect to this Agreement, the Notes or any other Loan Documents shall, unless signed by all the Banks, (i) increase or decrease the Commitment of any Bank (except for a ratable decrease in the Commitments of all Banks) or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any Loan or any fees hereunder or for any reduction or termination of any Commitment, (iv) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Banks, which shall be required for the Banks or any of them to take any action under this Section or any other provision of this Agreement, (v) release the EOPT Guaranty or (vi) modify the provisions of this Section 9.5.

          SECTION 9.6. Successors and Assigns.

          (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement or the other Loan Documents without the prior written consent of all Banks and the Administrative Agent and a Bank may not assign or otherwise transfer any of its interest under this Agreement except as permitted in subsections (b), (c) and (e) of this Section 9.6.

          (b) Prior to the occurrence of an Event of Default, any Bank may at any time from and after the date that is six (6) months after the Closing Date, with (and subject to) the consent of Borrower (which consent shall not be unreasonably withheld, conditioned or delayed), grant to an existing Bank, one or more banks, finance companies, insurance companies or other financial institutions (a “Participant”) in minimum amounts of not less than $5,000,000 (or any lesser amount in the case of participations to an existing Bank) participating interests in its Commitment or any or all of its Loans. After the occurrence and during the continuance of an Event of Default, any Bank may at any time grant to any Person in any amount (also a “Participant”), participating interests in its Commitment or any or all of its Loans. Any participation made during the continuation of an Event of Default shall not be affected by the subsequent cure of such Event of Default. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Any agreement pursuant to which any Bank may grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (i), (ii), (iii), (iv) or (v) of Section 9.5 without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article VIII with respect to its participating interest.

          (c) Any Bank may at any time assign to a Qualified Institution (in each case, an “Assignee”) (i) prior to the occurrence of an Event of Default and from and after the date that is six (6) months after the Closing Date, in minimum amounts of not less than Five Million Dollars ($5,000,000) and integral multiple of One Million Dollars ($1,000,000) thereafter (or any lesser amount in the case of assignments to an existing Bank) and (ii) after the occurrence and during the continuance of an Event of Default, in any amount, all or a proportionate part of all, of its rights and obligations under this Agreement, the Notes and the other Loan Documents, and, in either case, such Assignee shall assume such rights and obligations, pursuant to a Transfer Supplement in substantially the form of Exhibit B hereto executed by such Assignee and such transferor Bank; provided, that if no Event of Default shall

have occurred and be continuing, such assignment shall be subject to the Administrative Agent’s and the Borrower’s consent, which consent shall not be unreasonably withheld, conditioned or delayed; and provided further that if an Assignee is an affiliate of such transferor Bank and is an Affiliate Qualified Institution, or was a Bank immediately prior to such assignment, no such consent shall be required. Upon execution and delivery of such instrument and payment by such Assignee to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set forth in such instrument of assumption, and no further consent or action by any party shall be required and the transferor Bank shall be released from its obligations hereunder to a corresponding extent. Upon the consummation of any assignment pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee. In connection with any such assignment, the transferor Bank shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $2,500. If the Assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 8.4. Any assignment made during the continuation of an Event of Default shall not be affected by any subsequent cure of such Event of Default.

          (d) Intentionally Omitted.

          (e) Any Bank may at any time assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder.

          (f) No Assignee, Participant or other transferee of any Bank’s rights shall be entitled to receive any greater payment under Section 8.3 or 8.4 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist.

          (g) No Assignee of any rights and obligations under this Agreement shall be permitted to further assign less than all of such rights and obligations. No participant in any rights and obligations under this Agreement shall be permitted to sell subparticipations of such rights and obligations.

          (h) Anything in this Agreement to the contrary notwithstanding, so long as no Event of Default shall have occurred and be continuing, no Bank shall be permitted to enter into an assignment of, or sell a participation interest in, its rights and obligations hereunder which would result in such Bank holding a Commitment without participants of less than Five Million Dollars ($5,000,000) (or in the

case of the Administrative Agent, Thirty Million Dollars ($30,000,000)) unless as a result of a cancellation or reduction of the aggregate Commitments; provided, however, that no Bank shall be prohibited from assigning its entire Commitment so long as such assignment is otherwise permitted under this Section 9.6.

          SECTION 9.7. Collateral. Each of the Banks represents to the Administrative Agent and each of the other Banks that it in good faith is not relying upon any “margin stock” (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

          SECTION 9.8. Governing Law; Submission to Jurisdiction.

          (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW OTHER THAN SECTION 1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

          (b) Any legal action or proceeding with respect to this Agreement or any other Loan Document and any action for enforcement of any judgment in respect thereof may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York, and, by execution and delivery of this Agreement, the Borrower hereby accepts for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts and appellate courts from any thereof. The Borrower irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the hand delivery, or mailing of copies thereof by registered or certified mail, postage prepaid, to the Borrower at its address set forth below. The Borrower hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement or any other Loan Document brought in the courts referred to above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. Nothing herein shall affect the right of the Administrative Agent to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Borrower in any other jurisdiction.

          SECTION 9.9. Counterparts; Integration;. Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective upon receipt by the Administrative Agent and the Borrower of counterparts hereof signed by

each of the parties hereto (or, in the case of any party as to which an executed counterpart shall not have been received, receipt by the Administrative Agent in form satisfactory to it of telegraphic, telex or other written confirmation from such party of execution of a counterpart hereof by such party).

          SECTION 9.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE ADMINISTRATIVE AGENT, THE SYNDICATION AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          SECTION 9.11. Survival. All indemnities set forth herein shall survive the execution and delivery of this Agreement and the other Loan Documents and the making and repayment of the Loans hereunder.

          SECTION 9.12. Domicile of Loans. Each Bank may transfer and carry its Loans at, to or for the account of any domestic or foreign branch office, subsidiary or affiliate of such Bank.

          SECTION 9.13. Limitation of Liability. No claim may be made by the Borrower or any other Person acting by or through Borrower against the Administrative Agent, the Syndication Agent or any Bank or the affiliates, directors, officers, employees, attorneys or agent of any of them for any punitive damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by this Agreement or by the other Loan Documents, or any act, omission or event occurring in connection therewith; and the Borrower hereby waives, releases and agrees not to ▇▇▇ upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

          SECTION 9.14. Recourse Obligation. This Agreement and the Obligations hereunder are fully recourse to the Borrower. Notwithstanding the foregoing, no recourse under or upon any obligation, covenant, or agreement contained in this Agreement shall be had against (i) any officer, director, shareholder or employee of the Borrower or EOPT, or (ii) any general partner of Borrower other than EOPT, in each case except in the event of fraud or misappropriation of funds on the part of such officer, director, shareholder or employee or such general partner.

          SECTION 9.15. Confidentiality. The Administrative Agent and each Bank shall use reasonable efforts to assure that information about Borrower, EOPT and its Subsidiaries and Investment Affiliates, and the Properties thereof and their operations, affairs and financial condition, not generally disclosed to the public, which is furnished to Administrative Agent or any Bank pursuant to the provisions hereof or any other Loan Document is used only for the purposes of this Agreement and shall not be divulged to any Person other than the Administrative Agent, the Banks, and their affiliates and respective officers, directors, employees and agents who are actively and directly participating in the evaluation, administration or enforcement of the Loan and other transactions between such Bank

and the Borrower, except: (a) to their attorneys and accountants, (b) in connection with the enforcement of the rights and exercise of any remedies of the Administrative Agent and the Banks hereunder and under the other Loan Documents, (c) in connection with assignments and participations and the solicitation of prospective assignees and participants referred to in Section 9.6 hereof, who have agreed in writing to be bound by a confidentiality agreement substantially equivalent to the terms of this Section 9.15, and (d) as may otherwise be required or requested by any regulatory authority having jurisdiction over the Administrative Agent or any Bank or by any applicable law, rule, regulation or judicial process. Notwithstanding anything herein to the contrary, “information” shall not include, and the Administrative Agent and each Bank may disclose 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 and tax analyses) that are provided to the Administrative Agent or such Bank 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 portion of the documents or similar item that relate to the tax treatment or tax structure of the Loans and transactions contemplated hereby. The Administrative Agent and/or the Bank making any such disclosure shall endeavor to notify Borrower prior to making any such disclosure of the fact that such disclosure is being made and the nature of the disclosure. In addition, the Administrative Agent and/or such Bank shall provide Borrower with a copy of the disclosure promptly after the same is made.

          SECTION 9.16. Bank’s Failure to Fund.

          (a) If a Bank does not advance to Administrative Agent such Bank’s Pro Rata Share of a Loan in accordance herewith, then neither Administrative Agent nor the other Banks shall be required or obligated to fund such Bank’s Pro Rata Share of such Loan.

          (b) As used herein, the following terms shall have the meanings set forth below:

               (i) “Defaulting Bank” shall mean any Bank which (x) does not advance to the Administrative Agent such Bank’s Pro Rata Share of a Loan in accordance herewith for a period of five (5) Business Days after notice of such failure from Administrative Agent, (y) shall otherwise fail to perform such Bank’s obligations under the Loan Documents (including, without limitation, the obligation to purchase participations pursuant to Section 2.3) for a period of five (5) Business Days after notice of such failure from Administrative Agent, or (z) shall fail to pay the Administrative Agent or any other Bank, as the case may be, upon demand, such Bank’s Pro Rata Share of any costs, expenses or disbursements incurred or made by the Administrative Agent pursuant to the terms of the Loan Documents for a period of five (5) Business Days after notice of such failure from Administrative Agent, and in all cases, such failure is not as a result of a good faith dispute as to whether such advance is properly required to be made pursuant to the provisions of this Agreement, or as to whether such other performance or payment is properly required pursuant to the provisions of this Agreement.

               (ii) “Junior Creditor” means any Defaulting Bank which has not (x) fully cured each and every monetary default on its part under the Loan Documents and (y) unconditionally tendered to the Administrative Agent such Defaulting Bank’s Pro Rata Share of all costs, expenses and disbursements required to be paid or reimbursed pursuant to the terms of the Loan Documents.

               (iii) “Payment in Full” means, as of any date, the receipt by the Banks who are not Junior Creditors of an amount of cash, in lawful currency of the United States, sufficient to indefeasibly pay in full all Senior Debt.

               (iv) “Senior Debt” means (x) collectively, any and all indebtedness, obligations and liabilities of the Borrower to the Banks who are not Junior Creditors from time to time, whether fixed or contingent, direct or indirect, joint or several, due or not due, liquidated or unliquidated, determined or undetermined, arising by contract, operation of law or otherwise, whether on open account or evidenced by one or more instruments, and whether for principal, premium, interest (including, without limitation, interest accruing after the filing of a petition initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or otherwise, which arise under, in connection with or in respect of the Loans or the Loan Documents, and (y) any and all deferrals, renewals, extensions and refundings of, or amendments, restatements, rearrangements, modifications or supplements to, any such indebtedness, obligation or liability.

               (v) “Subordinated Debt” means (x) any and all indebtedness, obligations and liabilities of Borrower to one or more Junior Creditors from time to time, whether fixed or contingent, direct or indirect, joint or several, due or not due, liquidated or unliquidated, determined or undetermined, arising by contract, operation of law or otherwise, whether on open account or evidenced by one or more instruments, and whether for principal, premium, interest (including, without limitation, interest accruing after the filing of a petition initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or otherwise, which arise under, in connection with or in respect of the Loans or the Loan Documents, and (y) any and all deferrals, renewals, extensions and refundings of, or amendments, restatements, rearrangements, modifications or supplements to, any such indebtedness, obligation or liability.

          (c) Immediately upon a Bank’s becoming a Junior Creditor and until such time as such Bank shall have cured all applicable defaults, no Junior Creditor shall, prior to Payment in Full of all Senior Debt:

               (i) accelerate, demand payment of, ▇▇▇ upon, collect, or receive any payment upon, in any manner, or satisfy or otherwise discharge, any Subordinated Debt, whether for principal, interest and otherwise;

               (ii) take or enforce any Liens to secure Subordinated Debt or attach or levy upon any assets of Borrower, to enforce any Subordinated Debt;

               (iii) enforce or apply any security for any Subordinated Debt; or

               (iv) incur any debt or liability, or the like, to, or receive any loan, return of capital, advance, gift or any other property, from, the Borrower.

          (d) In the event of:

               (i) any insolvency, bankruptcy, receivership, liquidation, dissolution, reorganization, readjustment, composition or other similar proceeding relating to Borrower;

               (ii) any liquidation, dissolution or other winding-up of the Borrower, voluntary or involuntary, whether or not involving insolvency, reorganization or bankruptcy proceedings;

               (iii) any assignment by the Borrower for the benefit of creditors;

               (iv) any sale or other transfer of all or substantially all assets of the Borrower; or

               (v) any other marshaling of the assets of the Borrower;

each of the Banks shall first have received Payment in Full of all Senior Debt before any payment or distribution, whether in cash, securities or other property, shall be made in respect of or upon any Subordinated Debt. Any payment or distribution, whether in cash, securities or other property that would otherwise be payable or deliverable in respect of Subordinated Debt to any Junior Creditor but for this Agreement shall be paid or delivered directly to the Administrative Agent for distribution to the Banks in accordance with this Agreement until Payment in Full of all Senior Debt. If any Junior Creditor receives any such payment or distribution, it shall promptly pay over or deliver the same to the Administrative Agent for application in accordance with the preceding sentence.

          (e) Each Junior Creditor shall file in any bankruptcy or other proceeding of Borrower in which the filing of claims is required by law, all claims relating to Subordinated Debt that such Junior Creditor may have against Borrower and assign to the Banks who are not Junior Creditors all rights of such Junior Creditor thereunder. If such Junior Creditor does not file any such claim prior to forty-five (45) days before the expiration of the time to file such claim, Administrative Agent, as attorney-in-fact for such Junior Creditor, is hereby irrevocably authorized to do so in the name of such Junior Creditor or, in Administrative Agent’s sole discretion, to assign the claim to a nominee and to cause proof of claim to be filed in the name of such nominee. The foregoing power of attorney is coupled with an interest and cannot be revoked. The Administrative Agent shall, to the exclusion of each Junior Creditor, have the sole right, subject to Section 9.5 hereof, to accept or reject any plan proposed in any such proceeding and to take any other action that a party filing a claim is entitled to take. In all such cases, whether in administration, bankruptcy or otherwise, the Person or Persons

authorized to pay such claim shall pay to Administrative Agent the amount payable on such claim and, to the full extent necessary for that purpose, each Junior Creditor hereby transfers and assigns to the Administrative Agent all of the Junior Creditor’s rights to any such payments or distributions to which Junior Creditor would otherwise be entitled.

          (f) (i) If any payment or distribution of any character or any security, whether in cash, securities or other property, shall be received by any Junior Creditor in contravention of any of the terms hereof, such payment or distribution or security shall be received in trust for the benefit of, and shall promptly be paid over or delivered and transferred to, Administrative Agent for application to the payment of all Senior Debt, to the extent necessary to achieve Payment in Full. In the event of the failure of any Junior Creditor to endorse or assign any such payment, distribution or security, Administrative Agent is hereby irrevocably authorized to endorse or assign the same as attorney-in-fact for such Junior Creditor.

               (ii) Each Junior Creditor shall take such action (including, without limitation, the execution and filing of a financing statement with respect to this Agreement and the execution, verification, delivery and filing of proofs of claim, consents, assignments or other instructions that Administrative Agent may require from time to time in order to prove or realize upon any rights or claims pertaining to Subordinated Debt or to effectuate the full benefit of the subordination contained herein) as may, in Administrative Agent’s sole and absolute discretion, be necessary or desirable to assure the effectiveness of the subordination effected by this Agreement.

          (g) (i) Each Bank that becomes a Junior Creditor understands and acknowledges by its execution hereof that each other Bank is entering into this Agreement and the Loan Documents in reliance upon the absolute subordination in right of payment and in time of payment of Subordinated Debt to Senior Debt as set forth herein.

               (ii) Only upon the Payment in Full of all Senior Debt shall any Junior Creditor be subrogated to any remaining rights of the Banks which are not Defaulting Banks to receive payments or distributions of assets of the Borrower made on or applicable to any Senior Debt.

               (iii) Each Junior Creditor agrees that it will deliver all instruments or other writings evidencing any Subordinated Debt held by it to Administrative Agent, promptly after request therefor by the Administrative Agent.

               (iv) No Junior Creditor may at any time sell, assign or otherwise transfer any Subordinated Debt, or any portion thereof, including, without limitation, the granting of any Lien thereon, unless and until satisfaction of the requirements of Section 9.6 above and the proposed transferee shall have assumed in writing the obligation of the Junior Creditor to the Banks under this Agreement, in a form acceptable to the Administrative Agent.

               (v) If any of the Senior Debt, should be invalidated, avoided or set aside, the subordination provided for herein nevertheless shall continue in full force and effect and, as between the Banks which are not Defaulting Banks and all Junior Creditors, shall be and be deemed to remain in full force and effect.

               (vi) Each Junior Creditor hereby irrevocably waives, in respect of Subordinated Debt, all rights (x) under Sections 361 through 365, 502(e) and 509 of the Bankruptcy Code (or any similar sections hereafter in effect under any other Federal or state laws or legal or equitable principles relating to bankruptcy, insolvency, reorganizations, liquidations or otherwise for the relief of debtors or protection of creditors), and (y) to seek or obtain conversion to a different type of proceeding or to seek or obtain dismissal of a proceeding, in each case in relation to a bankruptcy, reorganization, insolvency or other proceeding under similar laws with respect to the Borrower. Without limiting the generality of the foregoing, each Junior Creditor hereby specifically waives (A) the right to seek to give credit (secured or otherwise) to the Borrower in any way under Section 364 of the Bankruptcy Code unless the same is subordinated in all respects to Senior Debt in a manner acceptable to Administrative Agent in its sole and absolute discretion and (B) the right to receive any collateral security (including, without limitation, any “super priority” or equal or “priming” or replacement Lien) for any Subordinated Debt unless the Banks which are not Defaulting Banks have received a senior position acceptable to the Banks in their sole and absolute discretion to secure all Senior Debt (in the same collateral to the extent collateral is involved).

          (h) (i) In addition to and not in limitation of the subordination effected by this Section 9.16, the Administrative Agent and each of the Banks which are not Defaulting Banks may in their respective sole and absolute discretion, also exercise any and all other rights and remedies available at law or in equity in respect of a Defaulting Bank; and

               (ii) The Administrative Agent shall give each of the Banks notice of the occurrence of a default under this Section 9.16 by a Defaulting Bank and if the Administrative Agent and/or one or more of the other Banks shall, at their option, fund any amounts required to be paid or advanced by a Defaulting Bank, the other Banks who have elected not to fund any portion of such amounts shall not be liable for any reimbursements to the Administrative Agent and/or to such other funding Banks.

          (i) Notwithstanding anything to the contrary contained or implied herein, a Defaulting Bank shall not be entitled to vote on any matter as to which a vote by the Banks is required hereunder, including, without limitation, any actions or consents on the part of the Administrative Agent as to which the approval or consent of all the Banks or the Majority Banks is required under Article VIII, Section 9.5 or elsewhere, so long as such Bank is a Defaulting Bank; provided, however, that in the case of any vote requiring the unanimous consent of the Banks, if all the Banks other than the Defaulting Bank shall have voted in accordance with each other, then the Defaulting Bank shall be deemed to have voted in accordance with such Banks.

          (j) Each of the Administrative Agent and any one or more of the Banks which are not Defaulting Banks may, at their respective option, (i) advance to the Borrower such Bank’s Pro Rata Share of the Loans not advanced by a Defaulting Bank in accordance with the Loan Documents, or (ii) pay to the Administrative Agent such Bank’s Pro Rata Share of any costs, expenses or disbursements incurred or made by the Administrative Agent pursuant to the terms of this Agreement not theretofore paid by a Defaulting Bank. Immediately upon the making of any such advance by the Administrative Agent or any one of the Banks, such Bank’s Pro Rata Share and the Pro Rata Share of the Defaulting Bank shall be recalculated to reflect such advance. All payments, repayments and other disbursements of funds by the Administrative Agent to Banks shall thereupon and, at all times thereafter be made in accordance with such Bank’s recalculated Pro Rata Share unless and until a Defaulting Bank shall fully cure all defaults on the part of such Defaulting Bank under the Loan Documents or otherwise existing in respect of the Loans or this Agreement, at which time the Pro Rata Share of the Bank(s) which advanced sums on behalf of the Defaulting Bank and of the Defaulting Bank shall be restored to their original percentages.

          SECTION 9.17. Banks’ ERISA Covenant. Each Bank, by its signature hereto or on the applicable Transfer Supplement, hereby agrees (a) that on the date any Loan is disbursed hereunder no portion of such Bank’s Pro Rata Share of such Loan will constitute “assets” within the meaning of 29 C.F.R. § 2510.3-101 of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code, and (b) that following such date such Bank shall not allocate such Bank’s Pro Rata Share of any Loan to an account of such Bank if such allocation (i) by itself would cause such Pro Rata Share of such Loan to then constitute “assets” (within the meaning of 29 C.F.R. § 2510.3-101) of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code and (ii) by itself would cause such Loan to constitute a prohibited transaction under ERISA or the Code (which is not exempt from the restrictions of Section 406 of ERISA and Section 4975 of the Code and the taxes and penalties imposed by Section 4975 of the Code and Section 502(i) of ERISA) or any Agent or Bank being deemed in violation of Section 404 of ERISA.

          SECTION 9.18. Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to Borrower or any party to the EOPT Guaranty, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Banks and the Administrative Agent (including any claim for the reasonable compensation,

expenses, disbursements and advances of the Banks and the Administrative Agent and their respective agents and counsel and other amounts due the Banks and the Administrative Agent hereunder allowed in such judicial proceeding); and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Banks, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel and other amounts due the Administrative Agent hereunder.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Bank any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Bank or to authorize the Administrative Agent to vote in respect of the claim of any Bank in any such proceeding.

          SECTION 9.19. USA Patriot Act. Each Bank hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank to identify the Borrower in accordance with the Act.

          SECTION 9.20. Public/Private Information. The Borrower hereby acknowledges that (a) the Administrative Agent and/or the Syndication Agent will make available to the Banks materials and/or information provided by or on behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on IntraLinks or another similar electronic system (the “Platform”) and (b) certain of the Banks may be “public-side” lenders (i.e., Banks that do not wish to receive material non-public information with respect to the Borrower or its securities) (each, a “Public Lender”). The Borrower hereby agrees that (w) all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower Materials “PUBLIC”, the Borrower shall be deemed to have authorized the Administrative Agent, the Syndication Agent, and the Banks to treat such Borrower Materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws (provided, however, that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 9.15); (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform marked “PUBLIC” or through a portion of the Platform designated “Public Investor;” and (z) the Administrative Agent and the Syndication Agent shall be entitled to treat any Borrower Materials that are not marked

“PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Investor.”

          WHEREAS, the Loans are evidenced by certain promissory notes (the “Notes”) of Borrower made to each of the Banks in accordance with the terms of the Credit Agreement;

          WHEREAS, the Credit Agreement and the Notes and any other documents executed in connection therewith are hereinafter collectively referred to as the “Loan Documents”;

          WHEREAS, capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Credit Agreement;

          WHEREAS, Guarantor is the sole general partner of Borrower; and

          WHEREAS, as a condition to the execution and delivery of the Loan Documents, the Banks have required that Guarantor execute and deliver this Guaranty; and

          NOW THEREFORE, in consideration of the premises and the benefits to be derived from the making of the Loans by the Banks to Borrower, and in order to induce the Administrative Agent, and the Banks to enter into the Credit Agreement and the other Loan Documents, the Guarantor hereby agrees as follows:

          1. Guarantor, on behalf of itself and its successors and assigns, hereby irrevocably, absolutely and unconditionally guarantees the full and punctual payment when due, whether at stated maturity or otherwise, of all Obligations of Borrower now or hereafter existing under the

Notes and the Credit Agreement, for principal and/or interest as well as any and all other amounts due thereunder, including, without limitation, all indemnity obligations of Borrower thereunder, and any and all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) incurred by the Administrative Agent or the Banks in enforcing their rights under this Guaranty (all of the foregoing obligations being the “Guaranteed Obligations”).

          2. It is agreed that the Guaranteed Obligations of Guarantor hereunder are primary and this Guaranty shall be enforceable against Guarantor and its successors and assigns without the necessity for any suit or proceeding of any kind or nature whatsoever brought by the Administrative Agent or any of the Banks against Borrower or its respective successors or assigns or any other party or against any security for the payment and performance of the Guaranteed Obligations and without the necessity of any notice of non-payment or non-observance or of any notice of acceptance of this Guaranty or of any notice or demand to which Guarantor might otherwise be entitled (including, without limitation, diligence, presentment, notice of maturity, extension of time, change in nature or form of the Guaranteed Obligations, acceptance of further security, release of further security, imposition or agreement arrived at as to the amount of or the terms of the Guaranteed Obligations, notice of adverse change in Borrower’s financial condition and any other fact which might materially increase the risk to Guarantor), all of which Guarantor hereby expressly waives; and Guarantor hereby expressly agrees that the validity of this Guaranty and the obligations of Guarantor hereunder shall in no way be terminated, affected, diminished, modified or impaired by reason of the assertion of or the failure to assert by the Administrative Agent or any of the Banks against Borrower or its respective successors or assigns, any of the rights or remedies reserved to the Administrative Agent or any of the Banks pursuant to the provisions of the Loan Documents. Guarantor agrees that any notice or directive given at any time to the Administrative Agent or any of the Banks which is inconsistent with the waiver in the immediately preceding sentence shall be void and may be ignored by the Administrative Agent and the Banks, and, in addition, may not be pleaded or introduced as evidence in any litigation relating to this Guaranty for the reason that such pleading or introduction would be at variance with the written terms of this Guaranty, unless the Administrative Agent has specifically agreed otherwise in a writing, signed by a duly authorized officer. Guarantor specifically acknowledges and agrees that the foregoing waivers are of the essence of this transaction and that, but for this Guaranty and such waivers, the Administrative Agent and the Banks would have declined to execute and deliver the Loan Documents.

          3. Guarantor waives, and covenants and agrees that it will not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any and all appraisal, valuation, stay, extension, marshalling-of-assets or redemption laws, or right of homestead or exemption, whether now or at any time hereafter in force, which may delay, prevent or otherwise affect the performance by Guarantor of its obligations under, or the enforcement by the Administrative Agent or any of the Banks of, this Guaranty. Guarantor further covenants and agrees not to set up or claim any defense, counterclaim, offset, setoff or other objection of any kind to any action, suit or proceeding in law, equity or otherwise, or to any demand or claim that may be instituted or made by the Administrative Agent or any of the Banks other than the defense of the actual timely payment and

performance by Borrower of the Guaranteed Obligations hereunder; provided, however, that the foregoing shall not be deemed a waiver of Guarantor’s right to assert any compulsory counterclaim, if such counterclaim is compelled under local law or rule of procedure, nor shall the foregoing be deemed a waiver of Guarantor’s right to assert any claim which would constitute a defense, setoff, counterclaim or crossclaim of any nature whatsoever against Administrative Agent or any Bank in any separate action or proceeding. Guarantor represents, warrants and agrees that, as of the date hereof, its obligations under this Guaranty are not subject to any counterclaims, offsets or defenses against the Administrative Agent or any Bank of any kind.

          4. The provisions of this Guaranty are for the benefit of the Administrative Agent and the Banks and their successors and permitted assigns, and nothing herein contained shall impair as between Borrower and the Administrative Agent and the Banks the obligations of Borrower under the Loan Documents.

          5. This Guaranty shall be a continuing, unconditional and absolute guaranty and the liability of Guarantor hereunder shall in no way be terminated, affected, modified, impaired or diminished by reason of the happening, from time to time, of any of the following, although without notice or the further consent of Guarantor:

     (a) any assignment, amendment, modification or waiver of or change in any of the terms, covenants, conditions or provisions of any of the Guaranteed Obligations or the Loan Documents or the invalidity or unenforceability of any of the foregoing; or

     (b) any extension of time that may be granted by the Administrative Agent to Borrower, any guarantor, or their respective successors or assigns, heirs, executors, administrators or personal representatives; or

     (c) any action which the Administrative and/or the Banks may take or fail to take under or in respect of any of the Loan Documents or by reason of any waiver of, or failure to enforce any of the rights, remedies, powers or privileges available to the Administrative Agent under this Guaranty or available to the Administrative Agent and/or the Banks at law, equity or otherwise, or any action on the part of the Administrative Agent and/or the Banks granting indulgence or extension in any form whatsoever; or

     (d) any sale, exchange, release, or other disposition of any property pledged, mortgaged or conveyed, or any property in which the Administrative Agent and/or the Banks have been granted a lien or security interest to secure any indebtedness of Borrower to the Administrative Agent and/or the Banks; or

     (e) any release of any person or entity who may be liable in any manner for the payment and collection of any amounts owed by Borrower to the Administrative Agent and/or

     the Banks; or

     (f) the application of any sums by whomsoever paid or however realized to any amounts owing by Borrower to the Administrative Agent and/or the Banks under the Loan Documents in such manner as the Administrative Agent shall determine in its sole discretion; or

     (g) Borrower’s or any guarantor’s voluntary or involuntary liquidation, dissolution, sale of all or substantially all of their respective assets and liabilities, appointment of a trustee, receiver, liquidator, sequestrator or conservator for all or any part of Borrower’s or Guarantor’s assets, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment, or the commencement of other similar proceedings affecting Borrower or any guarantor or any of the assets of any of them, including, without limitation, (i) the release or discharge of Borrower or any guarantor from the payment and performance of their respective obligations under any of the Loan Documents by operation of law, or (ii) the impairment, limitation or modification of the liability of Borrower or any guarantor in bankruptcy, or of any remedy for the enforcement of the Guaranteed Obligations under any of the Loan Documents, or Guarantor’s liability under this Guaranty, resulting from the operation of any present or future provisions of the Bankruptcy Code or other present or future federal, state or applicable statute or law or from the decision in any court; or

     (h) any improper disposition by Borrower of the proceeds of the Loans, it being acknowledged by Guarantor that the Administrative Agent or any Bank shall be entitled to honor any request made by Borrower for a disbursement of such proceeds and that neither the Administrative Agent nor any Bank shall have any obligation to see the proper disposition by Borrower of such proceeds.

          6. Guarantor agrees that if at any time all or any part of any payment at any time received by the Administrative Agent from Borrower or Guarantor under or with respect to this Guaranty is or must be rescinded or returned by the Administrative Agent or any Bank for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of Borrower or Guarantor), then Guarantor’s obligations hereunder shall, to the extent of the payment rescinded or returned, be deemed to have continued in existence notwithstanding such previous receipt by such party, and Guarantor’s obligations hereunder shall continue to be effective or reinstated, as the case may be, as to such payment, as though such previous payment had never been made.

          7. Until this Guaranty is terminated pursuant to the terms hereof, Guarantor (i) shall have no right of subrogation against Borrower or any entity comprising same by reason of any payments or acts of performance by Guarantor in compliance with the obligations of Guarantor hereunder, (ii) waives any right to enforce any remedy which Guarantor now or hereafter shall have against Borrower or any entity comprising same by reason of any one or more payment or acts of performance in compliance with the obligations of Guarantor hereunder and (iii) from and after an Event

of Default (as defined in the Credit Agreement), subordinates any liability or indebtedness of Borrower or any entity comprising same now or hereafter held by Guarantor or any affiliate of Guarantor to the obligations of Borrower under the Loan Documents. The foregoing, however, shall not be deemed in any way to limit any rights that Guarantor may have pursuant to the Agreement of Limited Partnership of Borrower or which it may have at law or in equity with respect to any other partners of Borrower.

          8. Guarantor represents and warrants to the Administrative Agent and the Banks with the knowledge that the Administrative Agent and the Banks are relying upon the same, as follows:

     (a) as of the date hereof, Guarantor is the sole general partner of Borrower;

     (b) based upon such relationships, Guarantor has determined that it is in its best interests to enter into this Guaranty;

     (c) this Guaranty is necessary and convenient to the conduct, promotion and attainment of Guarantor’s business, and is in furtherance of Guarantor’s business purposes;

     (d) the benefits to be derived by Guarantor from Borrower’s access to funds made possible by the Loan Documents are at least equal to the obligations undertaken pursuant to this Guaranty;

     (e) Guarantor is solvent and has full power and legal right to enter into this Guaranty and to perform its obligations under the term hereof and (i) Guarantor is organized and validly existing under the laws of the State of Maryland, (ii) Guarantor has complied with all provisions of applicable law in connection with all aspects of this Guaranty, and (iii) the person executing this Guaranty has all the requisite power and authority to execute and deliver this Guaranty;

     (f) to the best of Guarantor’s knowledge, there is no action, suit, proceeding, or investigation pending or threatened against or affecting Guarantor at law, in equity, in admiralty or before any arbitrator or any governmental department, commission, board, bureau, agency or instrumentality (domestic or foreign) which is likely to materially and adversely impair the ability of Guarantor to perform its obligations under this Guaranty;

     (g) the execution and delivery of and the performance by Guarantor of its obligations under this Guaranty have been duly authorized by all necessary action on the part of Guarantor and do not (i) violate any provision of any law, rule, regulation (including, without limitation, Regulation U or X of the Board of Governors of the Federal Reserve System of the United States), order, writ, judgment, decree, determination or award presently in effect having applicability to Guarantor or the organizational documents of Guarantor the consequences of which violation is likely to materially and adversely impair the ability of Guarantor to perform its

obligations under this Guaranty or (ii) violate or conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default under any indenture, agreement or other instrument to which Guarantor is a party, or by which Guarantor or any of its property is bound, the consequences of which violation, conflict, breach or default is likely to materially and adversely impair the ability of Guarantor to perform its obligations under this Guaranty;

     (h) this Guaranty has been duly executed by Guarantor and constitutes the legal, valid and binding obligation of Guarantor, enforceable against it in accordance with its terms except as enforceability may be limited by applicable insolvency, bankruptcy or other laws affecting creditors’ rights generally or general principles of equity, whether such enforceability is considered in a proceeding in equity or at law;

     (i) no authorization, consent, approval, license or formal exemption from, nor any filing, declaration or registration with, any Federal, state, local or foreign court, governmental agency or regulatory authority is required in connection with the making and performance by Guarantor of this Guaranty, except those which have already been obtained; and

     (j) Guarantor is not an “investment company” as that term is defined in, nor is it otherwise subject to regulation under, the Investment Company Act of 1940, as amended.

          9. Guarantor and Administrative Agent each acknowledge and agree that this Guaranty is a guarantee of payment and performance and not of collection and enforcement in respect of any obligations which may accrue to the Administrative Agent and/or the Banks from Borrower under the provisions of any Loan Document.

          10. Subject to the terms and conditions of the Credit Agreement, and in conjunction therewith, the Administrative Agent or any Bank may assign any or all of its rights under this Guaranty. In the event of any such assignment, the Administrative Agent shall give Guarantor prompt notice of same. If the Administrative Agent or any Bank elects to sell all the Loans or participations in the Loans and the Loan Documents, including this Guaranty, the Administrative Agent or any Bank may forward to each purchaser and prospective purchaser all documents and information relating to this Guaranty or to Guarantor, whether furnished by Borrower or Guarantor or otherwise, subject to the terms and conditions of the Credit Agreement.

          11. Guarantor agrees, upon the written request of the Administrative Agent, to execute and deliver to the Administrative Agent, from time to time, any modification or amendment hereto or any additional instruments or documents reasonably considered necessary by the Administrative Agent or its counsel to cause this Guaranty to be, become or remain valid and effective in accordance with its terms, provided, that, any such modification, amendment, additional instrument or document shall not increase Guarantor’s obligations or diminish its rights hereunder and shall be reasonably satisfactory as to form to Guarantor and to Guarantor’s counsel.

          12. The representations and warranties of Guarantor set forth in this Guaranty shall survive until this Guaranty shall terminate in accordance with the terms hereof.

          13. This Guaranty contains the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements relating to such subject matter and may not be modified, amended, supplemented or discharged except by a written agreement signed by Guarantor and the Administrative Agent.

          14. If all or any portion of any provision contained in this Guaranty shall be determined to be invalid, illegal or unenforceable in any respect for any reason, such provision or portion thereof shall be deemed stricken and severed from this Guaranty and the remaining provisions and portions thereof shall continue in full force and effect.

          15. This Guaranty may be executed in counterparts which together shall constitute the same instrument.

          16. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, telex, facsimile transmission followed by telephonic confirmation or similar writing) and shall be addressed to such party at the address set forth below or to such other address as may be identified by any party in a written notice to the others:

          17. Any acknowledgment or new promise, whether by payment of principal or interest or otherwise by Borrower or Guarantor, with respect to the Guaranteed Obligations shall, if the statute of limitations in favor of Guarantor against the Administrative Agent shall have commenced to run, toll the running of such statute of limitations, and if the period of such statute of limitations shall have expired, prevent the operation of such statute of limitations.

          18. This Guaranty shall be binding upon Guarantor and its successors and assigns and shall inure to the benefit of the Administrative Agent and the Banks and their successors and permitted assigns.

          19. The failure of the Administrative Agent to enforce any right or remedy hereunder, or promptly to enforce any such right or remedy, shall not constitute a waiver thereof, nor give rise to any estoppel against the Administrative Agent, nor excuse Guarantor from its obligations hereunder. Any waiver of any such right or remedy to be enforceable against the Administrative Agent must be expressly set forth in a writing signed by the Administrative Agent.

          20. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

               (b) Any legal action or proceeding with respect to this Guaranty and any action for enforcement of any judgment in respect thereof may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York, and, by execution and delivery of this Guaranty, the Guarantor hereby accepts for itself and in respect of its

property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts and appellate courts from any thereof. The Guarantor irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Guarantor at its address for notices set forth herein. The Guarantor hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Guaranty brought in the courts referred to above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. Nothing herein shall affect the right of the Administrative Agent to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Guarantor in any other jurisdiction.

               (c) GUARANTOR HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY AND ALL CLAIMS OR CAUSES OF ACTION BASED UPON OR ARISING OUT OF THIS GUARANTY. IT IS HEREBY ACKNOWLEDGED BY GUARANTOR THAT THE WAIVER OF A JURY TRIAL IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT TO ACCEPT THIS GUARANTY AND THAT THE LOANS MADE BY THE BANKS ARE MADE IN RELIANCE UPON SUCH WAIVER. GUARANTOR FURTHER WARRANTS AND REPRESENTS THAT SUCH WAIVER HAS BEEN KNOWINGLY AND VOLUNTARILY MADE, FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, THIS GUARANTY MAY BE FILED BY THE ADMINISTRATIVE AGENT IN COURT AS A WRITTEN CONSENT TO A NON-JURY TRIAL.

               (d) Guarantor does hereby further covenant and agree to and with the Administrative Agent that Guarantor may be joined in any action against Borrower in connection with the Loan Documents and that recovery may be had against Guarantor in such action or in any independent action against Guarantor (with respect to the Guaranteed Obligations), without the Administrative Agent first pursuing or exhausting any remedy or claim against Borrower or its successors or assigns. Guarantor also agrees that, in an action brought with respect to the Guaranteed Obligations in any jurisdiction, it shall be conclusively bound by the judgment in any such action by the Administrative Agent (wherever brought) against Borrower or its successors or assigns, as if Guarantor were a party to such action, even though Guarantor was not joined as a party in such action.

               (e) Guarantor agrees to pay all reasonable expenses (including, without limitation, attorneys’ fees and disbursements) which may be incurred by the Administrative Agent or the Banks in connection with the enforcement of their rights under this Guaranty, whether or not suit is initiated.

          21. Notwithstanding anything to the contrary contained herein, this Guaranty shall terminate and be of no further force or effect upon the full performance and payment of the Guaranteed

Obligations hereunder and the termination of the Commitments under the Credit Agreement. Upon termination of this Guaranty in accordance with the terms of this Guaranty, the Administrative Agent promptly shall deliver to Guarantor such documents as Guarantor or Guarantor’s counsel reasonably may request in order to evidence such termination.

          22. All of the Administrative Agent’s rights and remedies under each of the Loan Documents or under this Guaranty are intended to be distinct, separate and cumulative and no such right or remedy therein or herein mentioned is intended to be in exclusion of or a waiver of any other right or remedy available to the Administrative Agent.

          23. The Guarantor shall not use any assets of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Internal Revenue Code (the “Code”) to repay or secure the Loan, the Note, the Obligations or this Guaranty. The Guarantor shall not assign, sell, pledge, encumber, transfer, hypothecate or otherwise dispose of any of its rights or interests (direct or indirect) in Borrower, or attempt to do any of the foregoing or suffer any of the foregoing, or permit any party with a direct or indirect interest or right in Borrower to do any of the foregoing, if such action would cause the Note, the Loan, the Obligations, this Guaranty, or any of the Loan Documents or the exercise of any of the Administrative Agent’s or Bank’s rights in connection therewith, to constitute a prohibited transaction under ERISA or the Code (unless the Guarantor furnishes to the Administrative Agent a legal opinion satisfactory to the Administrative Agent that the transaction is exempt from the prohibited transaction provisions of ERISA and the Code (and for this purpose, the Administrative Agent and the Banks, by accepting the benefits of this Guaranty, hereby agree to supply Guarantor all relevant non-confidential, factual information reasonably necessary to such legal opinion and reasonably requested by Guarantor) or would otherwise result in the Administrative Agent or any of the Arrangers or Banks being deemed in violation of Sections 404 or 406 of ERISA or Section 4975 of the Code or would otherwise result in the Administrative Agent or the Banks being a fiduciary or party in interest under ERISA or a “disqualified person” as defined in Section 4975(e)(2) of the Code with respect to an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code. The Guarantor shall indemnify and hold each of the Administrative Agent and the Banks free and harmless from and against all loss, costs (including attorneys’ fees and expenses), expenses, taxes and damages (including consequential damages) that each of the Administrative Agent and the Banks may suffer by reason of the investigation, defense and settlement of claims and in obtaining any prohibited transaction exemption under ERISA necessary in Administrative Agent’s reasonable judgment as a result of Guarantor’s action or inaction or by reason of a breach of the foregoing provisions by Guarantor.

          24. This Guaranty shall become effective simultaneously with the making of the initial Loans under the Credit Agreement.
