DEFINITIONS

SECTION 1.1. Definitions. The following terms, as used herein, have the following meanings:

“Adjusted Interbank Offered Rate” as applicable to any Interest Period means a rate per annum equal to the quotient obtained (rounded upward, if necessary, to the next higher 1/100 of 1%) by dividing (i) the Interbank Offered Rate applicable during such Interest Period by (ii) 1.00 minus the Euro-Dollar Reserve Percentage.

“Administrative Agent” shall mean Bank of America, N.A. in its capacity as Administrative Agent hereunder, and its permitted successors in such capacity in accordance with the terms of this Agreement.

“Administrative Questionnaire” means with respect to each Bank, an administrative questionnaire in the form prepared by the Administrative Agent and submitted to the Administrative Agent (with a copy to the Borrower and the Documentation Agent) duly completed by such Bank.

“Agents” shall mean the Administrative Agent, the Documentation Agent and the Syndication Agent, collectively.

“Agreement” shall mean this Credit Agreement as the same may from time to time hereafter be modified, supplemented or amended.

“Applicable Interest Rate” means (i) with respect to any Fixed Rate Indebtedness, the fixed interest rate applicable to such Fixed Rate Indebtedness at the time in question, and (ii) with respect to any Floating Rate Indebtedness, either (x) the rate at which the interest rate applicable to such Floating Rate Indebtedness is actually capped (or fixed pursuant to an interest rate hedging device), at the time of calculation, if Borrower has entered into an interest rate cap agreement or other interest rate hedging device with respect thereto or (y) if Borrower has not entered into an interest rate cap agreement or other interest rate hedging device with respect to such Floating Rate Indebtedness, the greater of (A) the rate at which the interest rate applicable to such Floating Rate Indebtedness could be fixed for the remaining term of such Floating Rate Indebtedness, at the time of calculation, by Borrower’s entering into any unsecured interest rate hedging device either not requiring an upfront payment or if requiring an upfront payment, such upfront payment shall be amortized over the term of such device and included in the calculation of the interest rate (or, if such rate is incapable of being fixed by entering into an unsecured interest rate hedging device at the time of calculation, a fixed rate equivalent reasonably determined by Administrative Agent) or (B) the floating rate applicable to such Floating Rate Indebtedness at the time in question.

“Applicable Lending Office” means with respect to any Bank, (i) in the case of its Base Rate Loans, its Domestic Lending Office and (ii) in the case of its Euro-Dollar Loans, its Euro-Dollar Lending Office.

“Applicable Margin” means with respect to each Loan, the respective percentages per annum determined, at any time, based on the range into which Borrower’s Credit Rating then falls, in accordance with the table set forth below, subject to adjustment pursuant to Section 5.14. Any change in Borrower’s Credit Rating causing it to move to a different range on the table shall effect an immediate change in the Applicable Margin. In the event that Borrower receives only two (2) Credit Ratings, and such Credit Ratings are not equivalent, the Applicable Margin shall be determined by the lower of such two (2) Credit Ratings. In the event that Borrower receives more than two (2) Credit Ratings, and such Credit Ratings are not all equivalent, the Applicable Margin shall be determined by the higher of the ratings from S&P and Moody’s; provided that the rating from one of the other Rating Agencies shall be at least equivalent to such higher rating; provided, further, that if the rating from one of the other Rating Agencies is not at least equivalent to the higher of the ratings from S&P and Moody’s, then the Applicable Margin shall be determined by the second (2nd) highest Credit Rating. In the event that only one of the Rating Agencies shall have set Borrower’s Credit Rating, then the Applicable Margin shall be based on such rating only.

adjustment provided in clause (aa) of this proviso) which would cause such aggregate amount to exceed thirty-five percent (35%) of the total Unencumbered Asset Value at such time (after making all adjustments required by this proviso) will be disregarded in determining Unencumbered Asset Value, and (ee) the portion of the amount of the Unencumbered Asset Value attributable to all Qualifying Unencumbered Property located outside of the United States (after first taking into account the adjustment provided in clause (aa) of this proviso) which would cause such amount to exceed ten percent (10%) of the total Unencumbered Asset Value at such time (after making all adjustments required by this proviso) will be disregarded in determining Unencumbered Asset Value. Anything in the foregoing to the contrary notwithstanding, in the event that Borrower, a Financing Partnership or a Joint Venture Subsidiary disposes (for purposes of this definition of “Unencumbered Asset Value”, each, a “Disposition”) of (x) an interest in any Qualified Unencumbered Property (which was not acquired during the Fiscal Quarter most recently ended), (y) a direct or indirect interest in the owner of any such Property or (z) any such Property in such a manner that results in Borrower holding a direct or indirect interest in such Property or the owner of such Property, then, for purposes of the foregoing calculation of Unencumbered Asset Value, such Property shall be treated as follows:

(A) if, following a Disposition, an undivided interest in the Property is owned by Borrower or a Financing Partnership, then such undivided interest shall be treated as if Borrower or such Financing Partnership had owned such undivided interest in the Property for the entire Fiscal Quarter most recently ended;

(B) if, following a Disposition, the Property or an undivided interest in the Property is owned by a Joint Venture Subsidiary, then such Property or undivided interest shall be treated as if such Joint Venture Subsidiary had owned such Property for the entire Fiscal Quarter most recently ended; and

(C) and no such Property or undivided interest therein will be treated as having been disposed of or acquired in such Fiscal Quarter.

ARTICLE II

THE CREDITS

SECTION 2.1. Commitments to Lend. Each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make Loans to the Borrower pursuant to this Article in amounts such that the aggregate principal amount of Committed Loans by such Bank outstanding shall not exceed the amount of its Commitment. The Loans shall be in an aggregate principal amount not to exceed $1,000,000,000 and shall be made by the Lenders in a single disbursement to the Borrower on the Funding Date, subject to the terms and conditions set forth in this Agreement. In the event the Funding Date does not occur and the Loans are not advanced to Borrower on or before December 31, 2001, the Commitments shall expire and the Banks shall have no further obligation to advance the Loans to Borrower. The Borrowing shall be made from the several Banks ratably in proportion to their respective Commitments. Any amounts repaid may not be reborrowed.

SECTION 2.2. Notice of Borrowing. With respect to the Borrowing, the Borrower shall give Administrative Agent notice not later than 11:00 a.m. (Dallas, Texas time) (x) one Business Day before each Base Rate Borrowing, or (y) three Business Days before each Euro-Dollar Borrowing, specifying:

      (i)        the date of such Borrowing, which shall be a Business Day,

      (ii)       the aggregate amount of such Borrowing,

      (iii)      whether the Loans comprising such Borrowing are to be Base Rate Loans or Euro-Dollar Loans, and

      (iv)      in the case of a Euro-Dollar Borrowing, the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period.

SECTION 2.3. [Intentionally Omitted].

SECTION 2.4. [Intentionally Omitted].

SECTION 2.5. Notice to Banks; Funding of Loans.

(a) Upon receipt of a Notice of Borrowing from Borrower in accordance with Section 2.2, the Administrative Agent shall, on the date such Notice of Borrowing is received by the Administrative Agent, notify Documentation Agent and each Bank of the contents thereof

and of such Bank’s share of such Borrowing, of the interest rate determined pursuant thereto and the Interest
Period(s) (if different from those requested by the Borrower) and such Notice of Borrowing shall not thereafter be revocable by the Borrower, unless Borrower shall pay any applicable expenses pursuant to Section 2.13.

(b) Not later than 1:00 p.m. (Dallas, Texas time) on the date of the Borrowing as indicated in the applicable Notice of Borrowing, each Bank shall (except as provided in subsection (d) of this Section) make available its share of the Borrowing in Federal funds immediately available in Dallas, Texas, to the Administrative Agent at its address referred to in Section 9.1.

(d) Unless the Administrative Agent shall have received notice from a Bank prior to the date 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. If and to the extent that such Bank shall not have so made such share available to the 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. If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Loan included in such Borrowing for purposes of this Agreement. If such Bank shall not pay to Administrative Agent such corresponding amount after reasonable attempts are made by Administrative Agent to collect such amounts from such Bank, Borrower agrees to repay to Administrative Agent forthwith on demand such corresponding amounts together with interest thereto, for each day from the date such amount is made available to Borrower until the date such amount is repaid to Administrative Agent, at the interest rate applicable thereto one (1) Business Day after demand. Nothing contained in this Section 2.5(d) shall be deemed to reduce the Commitment of any Bank or in any way affect the rights of Borrower with respect to any defaulting Bank or Administrative Agent. The failure of any Bank to make available to the Administrative Agent such Bank’s share of any Borrowing in accordance with Section 2.5(b) shall not relieve any other Bank of its obligations to fund its Commitment, in accordance with the provisions hereof.

(e) Subject to the provisions hereof, the Administrative Agent shall make available each Borrowing to Borrower in Federal funds immediately available in accordance with, and on the date set forth in, the applicable Notice of Borrowing.

SECTION 2.6. Notes.

(a) The Loans of each Bank shall be evidenced by a single Note payable to the order of such Bank for the account of its Applicable Lending Office.

(b) Each Bank may, by notice to the Borrower, the Administrative Agent and the Documentation Agent, request that its Loans of a particular type be evidenced by a separate Note in an amount equal to the aggregate unpaid principal amount of such Loans. Any additional costs incurred by the Administrative Agent, the Borrower or the Banks in connection with preparing such a Note shall be at the sole cost and expense of the Bank requesting such Note. In the event any Loans evidenced by such a Note are paid in full prior to the Maturity Date, any such Bank shall return such Note to Borrower. Each such Note shall be in substantially the form of Exhibit A hereto with appropriate modifications to reflect the fact that it evidences solely Loans of the relevant type. Upon the execution and delivery of any such Note, any existing Note payable to such Bank shall be replaced or modified accordingly. Each reference in this Agreement to the “Note” of such Bank shall be deemed to refer to and include any or all of such Notes, as the context may require.

(c) Upon receipt of each Bank’s Note pursuant to Section 3.1(a), the Documentation Agent shall forward such Note to such Bank. Each Bank shall record the date, amount, type and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and may, if such Bank so elects in connection with any transfer or enforcement of its Note, endorse on the appropriate schedule appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Bank to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required.

(d) The Committed Loans shall mature, and the principal amount thereof shall be due and payable, on the Maturity Date.

(e) [Intentionally Omitted]

(f) There shall be no more than ten (10) Euro-Dollar Groups of Loans outstanding at any one time.

SECTION 2.7. Method of Electing Interest Rates.

(a) The Loans included in the Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article VIII), as follows:

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert all or any portion of such Loans to Euro-Dollar Loans as of any Business Day;

(ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert all or any portion of such Loans to Base Rate Loans and/or elect to continue all or any portion of such Loans as Euro-Dollar Loans for an additional Interest Period or additional Interest Periods, in each case effective on the last day of the then current Interest Period applicable to such Loans, or on such other date designated by Borrower in the Notice of Interest Rate Election provided Borrower shall pay any losses pursuant to Section 2.13.

Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the Administrative Agent at least three (3) Business Days before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group, (ii) the portion to which such Notice applies, and the remaining portion to which it does not apply, are each $500,000 or any larger multiple of $100,000, (iii) there shall be no more than ten (10) Euro-Dollar Groups of Loans outstanding at any time, (iv) no Committed Loan may be continued as, or converted into, a Euro-Dollar Loan when any Event of Default has occurred and is continuing, and (v) no Interest Period shall extend beyond the Maturity Date.

(b) Each Notice of Interest Rate Election shall specify:

(i) the Group of Loans (or portion thereof) to which such notice applies;

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of subsection (a) above;

(iii) if the Loans comprising such Group are to be converted, the new type of Loans and, if such new Loans are Euro-Dollar Loans, the duration of the initial Interest Period applicable thereto; and

(iv) if such Loans are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Upon receipt of a Notice of Interest Rate Election from the Borrower pursuant to subsection (a) above, the Administrative Agent shall notify the Documentation Agent and each Bank the same day as it receives such Notice of Interest Rate Election of the contents thereof, the interest rates determined pursuant thereto and the Interest Periods (if different from those requested by the Borrower) and such notice shall not thereafter be revocable by the

Borrower. If the Borrower fails to deliver a timely Notice of Interest Rate Election to the Administrative Agent for any Group of Euro-Dollar Loans, such Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto.

SECTION 2.8. Interest Rates.

(a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made until the date it is repaid or converted into a Euro-Dollar Loan pursuant to Section 2.7, at a rate per annum equal to the Base Rate for Base Rate Loans for such day.

(b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during the Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin for Euro-Dollar Loans for such day plus the Adjusted Interbank Offered Rate applicable to such Interest Period.

(d) In the event that, and for so long as, any Event of Default shall have occurred and be continuing, the outstanding principal amount of the Loans, and, to the extent permitted by applicable law, overdue interest in respect of all Loans, shall bear interest at the annual rate equal to the sum of the Base Rate and four percent (4%) (the “Default Rate”).

(e) The Administrative Agent shall determine each interest rate applicable to the Loans 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 or 90 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.

SECTION 2.9. Fees.

(a) Unused Facility Fee. In the event Loans are not advanced to Borrower on or before July 16, 2001, for the period beginning on July 16, 2001 (the “Fee Accrual Date”) and ending on the date the Loans are advanced to Borrower (the “Unused Facility Fee Period”), the Borrower shall pay to the Administrative Agent, for the account of the Banks ratably in propor-

tion to their respective Commitments, an unused fee at an annual rate equal to the product of (i) the aggregate Commitments (less any portion of the Commitments that has been cancelled by Borrower) and (ii) 0.15%. The unused fee shall be payable in arrears on the first day of each calendar month commencing on August 1, 2001 for the period during the prior calendar month that falls within the Unused Facility Fee Period that the Loans were not advanced to Borrower.

(b) Facility Fee. In the event any Loan is outstanding on the date that is one hundred twenty (120) days following the Funding Date, Borrower shall pay to the Administrative Agent, on such date for the account of the Banks ratably in proportion to their respective Commitments, a facility fee in the amount of 0.20% of the aggregate outstanding principal amount of the Loans on such date.

(c) Fees Non-Refundable. All fees set forth in this Section 2.9 shall be deemed to have been earned on the date payment is due in accordance with the provisions hereof and shall be non-refundable. The obligation of the Borrower to pay such fees in accordance with the provisions hereof shall be binding upon the Borrower and shall inure to the benefit of the Administrative Agent, the Documentation Agent, the Syndication Agent and the Banks regardless of whether any Loans are actually made.

(g) Any amounts so prepaid pursuant to this Section 2.11 may not be reborrowed. In the event Borrower elects to cancel all or any portion of the Commitments pursuant to this Section 2.11, such amounts may not be borrowed.

All amounts due hereunder shall be payable, without any counterclaim, setoff or deduction whatsoever, at the office of Administrative Agent at the address set forth on the signature page of this Agreement or at such other place as Administrative Agent may from time to time designate in writing. The Administrative Agent will promptly (and in any event within one (1) Business Day after receipt thereof) distribute to each Bank its ratable share of each such payment received by the Administrative Agent for the account of the Banks. 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 (Dallas, Texas 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. Whenever any payment of principal of, or interest on the Base Rate Loans or of fees shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business Day.

If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate.

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 sheet of EOPT as of December 31, 2000, and the related statements of operations and cash flows of EOPT for the fiscal year then ended, reported on by Ernst & Young LLP, fairly present, in conformity with GAAP, the consolidated financial position of EOPT as of such date and the consolidated results of operations and cash flows for such fiscal year.

(b) Since March 31, 2001, (i) except as may have been disclosed in writing to the Banks, nothing has occurred 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 or proceeding 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.

(a) Except as set forth on Schedule 4 .6 attached hereto, neither Borrower nor EOPT is a member of or has entered into, maintained, contributed to, or been required to contribute to, or may incur any liability with respect to any Plan or Multiemployer Plan or any other Benefit Arrangement.

(b) Except for a “prohibited transaction” arising solely because of a Bank’s breach of the covenant set forth in Section 9.17, 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, Documentation 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, the Documentation 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, the Documentation 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, Documentation 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 Documentation 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 or public body or 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 4.16. 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. As of the Closing Date, 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 the Borrower is not 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.

SECTION 4.22. Brokers’ Fees. 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 Documenta-

tion Agent, the Syndication Agent and the Banks, and certain other Persons as previously disclosed in writing to the Administrative Agent and certain fees relating to the Spieker Merger.

SECTION 4.23. Labor Matters. Except as disclosed on Schedule 4.6, there are no collective bargaining agreements or Multiemployer Plans covering the employees of the Borrower or any member of the ERISA Group and neither the Borrower nor any member of the ERISA Group has suffered any strikes, walkouts, work stoppages or other material labor difficulty within the last five years.

SECTION 4.24. Insurance. The Borrower currently maintains 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.

SECTION 5.6. Inspection of Property, Books and Records.

reasonably be desired. Administrative Agent shall coordinate any such visit or inspection to arrange for review by any Bank requesting any such visit or inspection.

(b) EBITDA to Interest Expense Ratio. Borrower shall not permit the ratio of EBITDA for the then most recently completed Fiscal Quarter to Interest Expense for the then most recently completed Fiscal Quarter to be less than 2.00:1.

(i) Dividends. The Borrower will not, as determined on an aggregate annual basis, pay any partnership distributions in excess of 90% of the Borrower’s FFO for such year.

During the continuance of a monetary Event of Default, Borrower shall only pay partnership distributions that are necessary to enable EOPT to make those dividends necessary to maintain EOPT’s status as a real estate investment trust.

(j) Permitted Holdings. Borrower’s primary business will be the ownership, operation and development of Office Properties and Parking Properties and any other business activities of Borrower and its Subsidiaries will remain incidental thereto. Notwithstanding the foregoing, Borrower and its Subsidiaries may acquire or maintain Permitted Holdings if and so long as the aggregate value of Permitted Holdings, whether held directly or indirectly by Borrower does not exceed, at any time, twenty-five percent (25%) of Total Asset Value of Borrower unless a greater percentage is approved by the Majority Banks (which approval shall not be unreasonably withheld, conditioned or delayed); provided, however, Borrower and its Subsidiaries may not acquire or maintain (i) Unimproved Assets if and to the extent that the aggregate value of Unimproved Assets, whether held directly or indirectly by Borrower, exceeds, at any time ten percent (10%) of Total Asset Value of Borrower or (ii) interests in Taxable REIT Subsidiaries if and to the extent that the aggregate value of interests in Taxable REIT Subsidiaries, whether held directly or indirectly by Borrower exceeds, at any time, twenty percent (20%) of Total Asset Value of Borrower unless, in either case, a greater percentage is approved by the Majority Banks (which approval shall not be unreasonably withheld, conditioned or delayed).

(k) No Liens. Borrower and EOPT shall not, and shall not allow any of their Subsidiaries, Financing Partnerships or Joint Venture Subsidiaries to, allow any Qualifying Unencumbered Property (or any equity interests in such Property that are owned directly or indirectly by Borrower, EOPT or any Joint Venture Parent), that is necessary to comply with the provisions of Sections 5.8(f) and (g), to become subject to a Lien that secures the Indebtedness of any Person, other than Permitted Liens.

(l) Calculation. Each of the foregoing ratios and financial requirements shall be calculated as of the last day of each Fiscal Quarter.

SECTION 5.9. Restriction on Fundamental Changes.

market value of the assets of the entity which is merged into the Borrower or EOPT is less than twenty-five percent (25%) of the Borrower’s or EOPT’s then Total Asset Value following such merger. Neither the Borrower nor EOPT shall liquidate, wind-up or dissolve (or suffer any liquidation or dissolution), discontinue its business or convey, lease, sell, transfer or otherwise dispose of, in one transaction or series of transactions, all or substantially all of its business or property, whether now or hereafter acquired. Nothing in this Section shall be deemed to prohibit the sale or leasing of portions of the Real Property Assets in the ordinary course of business. Notwithstanding anything in this Agreement to the contrary, the parties hereto hereby agree that the Majority Banks shall be deemed to have approved the terms of the Spieker Merger set forth in the Agreement and Plan of Merger, dated February 22, 2001, by and among Borrower, EOPT and Spieker Properties.

(b) The Borrower shall not amend its agreement of limited partnership or other organizational documents in any manner that would have a Material Adverse Effect without the Majority Banks’ consent, which shall not be unreasonably withheld. Without limitation of the foregoing, no Person shall be admitted as a general partner of the Borrower other than EOPT. EOPT shall not amend its declaration of trust, by-laws, or other organizational documents in any manner that would have a Material Adverse Effect without the Majority Banks’ consent, which shall not be unreasonably withheld. The Borrower shall not make any “in-kind” transfer of any of its property or assets to any of its constituent partners if such transfer would result in an Event of Default under Section 6.1(b) by reason of a breach of the provisions of Section 5.8.

(c) Subject to the provisions of clause (b) above, the Borrower shall deliver to Administrative Agent copies of all amendments to its agreement of limited partnership or to EOPT’s declaration of trust, by-laws, or other organizational documents no less than ten (10) days after the effective date of any such amendment.

SECTION 5.10. Changes in Business.

(a) Except for Permitted Holdings, neither the Borrower nor EOPT shall enter into any business which is substantially different from that conducted by the Borrower or EOPT on the Closing Date after giving effect to the transactions contemplated by the Loan Documents. The Borrower shall carry on its business operations through the Borrower, its Consolidated Subsidiaries and its Investment Affiliates.

(b) Except for Permitted Holdings, Borrower shall not engage in any line of business other than ownership, operation and development of Office Properties and Parking Properties and the provision of services incidental thereto, whether directly or through its Consolidated Subsidiaries and Investment Affiliates.

(d) Environmental Liabilities. Neither EOPT nor any of its Subsidiaries shall become subject to any Environmental Claim which has a Material Adverse Effect, including, without limitation, any arising out of or related to (i) the release or threatened release of any Material of Environmental Concern into the environment, or any remedial action in response thereto, or (ii) any violation of any Environmental Laws. Notwithstanding the foregoing provision, EOPT shall have the right to contest in good faith any claim of violation of an Environmental Law by appropriate legal proceedings and shall be entitled to postpone compliance with the obligation being contested as long as (i) no Event of Default shall have occurred and be continuing, (ii) EOPT shall have given Administrative Agent prior written notice of the commencement of such contest, (iii) noncompliance with such Environmental Law shall not subject EOPT or such Subsidiary to any criminal penalty or subject Administrative Agent,

Documentation Agent or any Bank to pay any civil penalty or to prosecution for a crime, and (iv) no portion of any Property material to Borrower or its condition or prospects shall be in substantial danger of being sold, forfeited or lost, by reason of such contest or the continued existence of the matter being contested.

(e) Disposal of Partnership Interests. EOPT will not directly or indirectly convey, sell, transfer, assign, pledge or otherwise encumber or dispose of any of its partnership interests in Borrower or any of its equity interest in any of the partners of the Borrower as of the date hereof (except in connection with the dissolution or liquidation of such partners of the Borrower), except for the reduction of EOPT’s interest in the Borrower arising from Borrower’s issuance of partnership interests in the Borrower or the retirement of preference units by Borrower. EOPT will continue to be the managing general partner of Borrower.

SECTION 5.12. Other Indebtedness. Borrower and EOPT shall not allow any of their Subsidiaries, Financing Partnerships or Joint Venture Subsidiaries that own, directly or indirectly, any Qualifying Unencumbered Property to directly or indirectly create, incur, assume or otherwise become or remain liable with respect to any Indebtedness other than trade debt incurred in the ordinary course of business and Indebtedness owing to Borrower, if the resulting failure of such Property to qualify as a Qualifying Unencumbered Property would result in an Event of Default under Section 5.8.

SECTION 5.13. Forward Equity Contracts. If Borrower shall enter into any forward equity contracts, Borrower may only settle the same by delivery of stock, it being agreed that if Borrower shall settle the same with cash, the same shall constitute an Event of Default hereunder.

SECTION 5.14. Syndication.

(a) In the event any Loan is outstanding on the date that is one hundred twenty (120) days following the date of the Funding Date by Borrower, the Arrangers shall have the right to syndicate the Loans to financial institutions and shall have the rights provided in the Fee Letter and all of such terms are incorporated herein in connection with such syndication. In the event the Arrangers commence syndication efforts the Borrower and EOPT shall actively assist the Arrangers in completing such syndication as reasonably requested by the Arrangers. Such assistance shall include (a) the Borrower and EOPT using commercially reasonable efforts to ensure that the syndication efforts benefit materially from the Borrower’s and EOPT’s existing lending relationships; (b) the Borrower and EOPT assisting in the preparation of a confidential information memorandum and other marketing materials to be used in connection with the syndication by providing the information described in this Section
5.14(b), below; and (c) the Borrower and EOPT making their senior management and advisors available to participate, upon reasonable notice, in information meetings for potential syndicate members at such times and places as the Arrangers may reasonably request.

(b) The Arrangers will jointly manage all aspects of the syndication, provided that decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted and which institutions will participate, will be made by mutual agreement of the Arrangers and the Borrower and the allocations of the commitments among the Lenders and the amount and distribution of fees among the Lenders will be determined by the Arrangers, the Agents and the Lead Lenders. The Arrangers will have no responsibility other than to arrange the syndication. To assist the Arrangers in their syndication efforts, the Borrower and EOPT shall promptly prepare and provide to the Arrangers all information with respect to the Borrower and EOPT and the transactions contemplated hereby, including all financial information and projections (the “Projections”), as the Arrangers may reasonably request in connection with the arrangement and syndication of the Loans, so long as disclosure by the Borrower, EOPT or any of their respective Subsidiaries, of such information would not result in a violation of, or expose the Borrower, EOPT or their respective Subsidiaries to any material liability under, any applicable law, ordinance or regulation or any agreements with unaffiliated third parties which are binding on the Borrower, EOPT or any of their respective Subsidiaries or on any Property of any of them. The Borrower and EOPT shall use commercially reasonable efforts to obtain any necessary consents or waivers under any such agreements to disclose such information to the Arrangers, the Agents and the Banks. The Borrower and EOPT represent and covenant that (a) all information other than the Projections (the “Information”) that has been or will be made available to the Arrangers by the Borrower, EOPT or any of their respective representatives is or will be, when furnished, complete and correct in all material respects and does not or will not, when furnished, contain any material misstatement or omission of fact and (b) the Projections that have been or will be made available to the Arrangers by the Borrower, EOPT or any of their representatives have been or will be prepared in good faith based upon assumptions believed to be reasonable at the time of preparation thereof. The Borrower and the Guarantor agree to supplement the Information and Projections on the one hundred twentieth (120th) day following the Funding Date and from time to time upon request of the Arrangers or the Agents from the Closing Date until the completion of any syndication of the Loans as contemplated by this Section 5.14 so all Information is complete and correct in all material respects and does not contain any material misstatements or omissions of fact. The Borrower and EOPT understand that in arranging and syndicating the Loans the Arrangers, the Agents and the Banks may use and rely on the Information and Projections without independent verification thereof.

(c) Prior to and during the syndication of the Loans, the Borrower and EOPT shall not entertain or undertake any competing offering, placement or arrangement of any bank financing other than property-specific mortgage debt and property-specific mezzanine debt not prohibited by this Agreement by or on behalf of the Borrower, EOPT or any affiliate thereof, unless otherwise agreed by the Arrangers and the Agents.

(d) The initial syndication of the Loan shall be allocated among the Banks as provided in the Syndication Letter.

In the event that the any Agent 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, such Agent, as the case may be, shall reimburse the Banks which previously made the payment(s) pro rata, based upon the actual amounts which were theretofore paid by each Bank. Each Agent, as the case may be, 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 Documentation Agent, the Syndication Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent, Documentation Agent, the Syndication Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement.

SECTION 7.8. Successor Administrative Agent, Documentation Agent or Syndication Agent. The Administrative Agent, the Documentation Agent or the Syndication Agent may resign at any time by giving notice thereof to the Banks, the Borrower and each other and the Administrative Agent shall resign in the event its Commitment or the Loans held by the Administrative Agent 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, Documentation Agent or Syndication Agent, as applicable, which successor Administrative Agent, successor

Documentation 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 or delayed (except that Borrower shall, in all events, be deemed to have approved The Chase Manhattan Bank or Citicorp Real Estate, Inc, as a successor Administrative Agent; The Chase Manhattan Bank or Bank of America, N.A. as a successor Documentation Agent; and Bank of America, N.A. or Citicorp Real Estate, Inc. as successor Syndication Agent). If no successor Administrative Agent, Documentation 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, Documentation Agent or Syndication Agent (as applicable) gives notice of resignation, then the retiring Administrative Agent, retiring Documentation Agent, or retiring Syndication Agent (as applicable) may, on behalf of the Banks, appoint a successor Administrative Agent, Documentation Agent or Syndication Agent (as applicable), which shall be the Administrative Agent, the Documentation Agent or the Syndication Agent as the case may be, who shall act until the Majority Banks shall appoint an Administrative Agent, Documentation Agent or Syndication Agent. Any appointment of a successor Administrative Agent, Documentation Agent or Syndication Agent by Majority Banks or the retiring Administrative Agent, the Documentation 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 or delayed. Upon the acceptance of its appointment as the Administrative Agent, Documentation Agent or Syndication Agent hereunder by a successor Administrative Agent or successor Documentation Agent or successor Syndication Agent, as applicable, such successor Administrative Agent, successor Documentation 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, retiring Documentation Agent or retiring Syndication Agent, as applicable, and the retiring Administrative Agent, the retiring Documentation Agent or the retiring Syndication Agent, as applicable, shall be released and discharged from its duties and obligations hereunder. After any retiring Administrative Agent’s, retiring Documentation 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, the Documentation 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 or Documentation Agent in its capacity as a Bank, as applicable), Administrative Agent, Documentation Agent or Syndication Agent may be removed at any time by giving at least thirty (30) Business Days prior written notice to Administrative Agent, Documentation Agent, Syndication Agent and Borrower. Such resignation or removal shall take effect upon the acceptance of appointment by a successor Administrative Agent, Documentation 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 disap-

proval 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 Required Banks, 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 Required Banks, 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 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 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(c).

SECTION 8.3. Increased Cost and Reduced Return.

(a) If, on or after the date hereof in the case of Committed Loans made pursuant to Section 2.1 (the “Loan Effective Date”), 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 (but excluding with respect to any Euro-Dollar Loan any such requirement reflected in an applicable Euro-Dollar Reserve Percentage)), 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 and Documentation 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 and Documentation 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(c).

SECTION 8.4. Taxes.

(a) Any and all payments by the Borrower to or for the account of any Bank, the Documentation Agent 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, the Documentation Agent 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, the Documentation Agent 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, Documentation Agent 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, the Documentation Agent 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) The Borrower agrees to indemnify each Bank, the Documentation Agent 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, the Documentation Agent or the Administrative Agent (as the case may be) and, so long as such Bank, Documentation Agent 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, the Documentation Agent or the Administrative Agent (as the case may be) makes demand therefor.

(d) 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 4224, as appropriate, or any successor form prescribed by the Internal Revenue Service, and (B) an Internal Revenue Service Form W-8 or W-9, 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 or 4224, 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 a Form W-8 or W-9, 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).

(e) 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.

(f) 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.

(g) 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.

(c) Except for liability of each Bank for damages incurred by the Borrower or EOPT to Spieker Properties in connection with a default by the Borrower or EOPT under the Borrower’s agreement with Spieker Properties that results solely and directly from a breach of the obligations of such Bank under this Agreement (or directly in combination with such Bank’s

breach and a breach of the obligations of another Bank under this Agreement), no Arranger, Agent or Bank shall be liable for any special, indirect, consequential or punitive damages in connection with its activities related to this Agreement or for any special, indirect, consequential or punitive damages in connection with this Agreement.

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 and the Documentation 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 is 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) shall be effective unless signed by the Borrower and the Required Banks and (B) no such amendment or waiver with respect to this Agreement, the Notes or any other Loan Docu-

ments 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 subsection (b) and (c) of this Section 9.6.

(b) Any Bank may at any time grant to an existing Bank, one or more banks, finance companies, insurance companies or other financial institutions (a “Participant“), at any time after the date that is one hundred twenty (120) days following the Funding Date, or at any time after the occurrence and during the continuance of an Event of Default, 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. 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, the Documentation Agent 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 after the date that is one hundred twenty (120) days following the Funding Date, or at any time after the occurrence and during the continuance of an Event of Default, assign to a Qualified Institution (in each case, an “Assignee“) (i) prior to the occurrence of an Event of Default, 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 C 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 or delayed; and provided further that if an Assignee is an affiliate of such transferor Bank 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 each Lead Lender, Ten Million Dollars ($10,000,000)) 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).

(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 or the Documentation 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 Documentation 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 DOCUMENTATION 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 Documentation 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 sue 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 (other than pursuant to the Acorn Guaranty (as defined in the EOPT Guaranty)) 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, the Documentation Agent and each Bank shall use reasonable efforts to assure that information about Borrower, EOPT and its Subsidiaries and Investments Affiliates, and the Properties thereof and their operations, affairs and financial condition, not generally disclosed to the public, which is furnished to Administrative Agent, the Documentation 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 Documentation 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, the Documentation 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, 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, the Documentation Agent or any Bank or by any applicable law, rule, regulation or judicial process.

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, Documentation 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, Documentation 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 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, sue 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, 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 Administra- tive 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 Administra- tive 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 Required Banks or 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 accor- dance 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. Section 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. Section 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.
