unless Borrower complies with the terms of Section 2.2.3(g) and (c) subject to Sections 2.2.3(d) and 2.2.3(e), any Conversion or Continuation of Loans shall be pro rata among the Lenders. Notwithstanding the foregoing, and without limiting the rights and remedies of the Administrative Agent and the Lenders under Article X, in the event that any Event of Default exists, the Administrative Agent may (and at the request of the Majority Lenders shall) suspend the right of Borrower to Convert any Loan into a LIBOR Loan, or to Continue any Loan as a LIBOR Loan for so long as such Event of Default exists, in which event all Loans shall be Converted (on the last day(s) of the respective Interest Periods therefor) or Continued, as the case may be, as Base Rate Loans. In connection with any such Conversion, a Lender may (at its sole and absolute discretion) transfer a Loan from one Applicable Lending Office to another. The amount to be Converted or Continued for any Interest Period shall be determined after giving effect to the amounts to be applied from the Sweep Account in repayment of the principal of the Loan on the Monthly Payment Date for the immediately preceding Interest Period in accordance with clause Eighth of Section 3 of the Modification Agreement and the Cash Management Agreement. At least three (3) Business Days prior to that Monthly Payment Date, Borrower shall contact Administrative Agent in order for Borrower and Administrative Agent to agree upon a calculation of the sums that are projected to be available for application from the Sweep Account in repayment of the principal of the Loan on such Monthly Payment Date based on the balance in the Deposit Account (and subaccounts thereof) as of the date three (3) Business Days prior to such Monthly Payment Date (the amount of principal so projected to be repaid by Borrower on any Monthly Payment Date, as agreed to by Borrower and the Administrative Agent, is referred to herein as the “Projected Principal Pay-Down Amount” for such Monthly Payment Date), and in no event shall Borrower deliver to Administrative Agent pursuant to this Section 2.2.3(b) any election with respect to the Conversion or Continuation of Loans if the aggregate principal balance of the Loans after giving effect to such Conversion or Continuation would exceed the aggregate principal balance of the Loans that would be outstanding after giving effect to the application from the Sweep Account in repayment of the principal of the Loan on such Monthly Payment Date of the Projected Principal Pay-Down Amount for such Monthly Payment Date.

(kk)    Section 2.2.3(d) of the Loan Agreement is hereby amended as follows:

Whenever any additional amount is payable by Borrower with respect to a Lender pursuant to this Section 2.2.3(d), Borrower shall, as promptly as possible thereafter, send to such Lender an original official receipt, if available, or certified copy thereof showing payment of such amount. Borrower hereby indemnifies Lender for any incremental taxes, interest or penalties that may become payable by a Lender which may result from any failure by Borrower to pay any such amount when due to the appropriate taxing authority or any failure by Borrower to remit to Lender the required receipts or other required documentary evidence.

For the purposes hereof, (A) “U.S. Person” means a citizen, national or resident of the United States of America, a corporation, limited liability company, partnership or other entity created or organized in or under any laws of the United States of America or any State thereof, or any estate or trust that is subject

If Borrower fails to select the Type of Loan within the time period (i.e., three (3) Business Days prior to the first day of the next applicable Interest Period) and otherwise as provided in this Section 2.3.5(e), such Loan (if outstanding as a LIBOR Loan) will be automatically Continued as a LIBOR Loan with an Interest Period of one (1) month on the last day of the current Interest Period for such Loan (based on a LIBOR Rate determined two (2) Business Days prior to the first day of the next Interest Period) or, if outstanding as a Base Rate Loan, will remain as a Base Rate Loan.

(qq)    Section 2.4.1 of the Loan Agreement is hereby modified as follows:

(i)    The words “On and after the Permitted Prepayment Date Borrower may, at its option and upon at least ten (10) Business Days” starting on the second (2^nd) line are hereby replaced with “Borrower may, at its option and upon at least three (3) Business Days”.

(iii)    The following sentence is hereby added at the end of Section 2.4.1 of the Loan Agreement:

Notwithstanding anything to the contrary in Section 3 of the Modification Agreement or the Cash Management Agreement, the amount equal to the Required Principal Payment that Borrower deposits into the Sweep Account at or prior to the Modification Effectiveness Time pursuant to Section 1(b) of the Modification Agreement shall be held in the Sweep Account as collateral for the Loan subject to the provisions of this Section 2.4.1. At any time after the Modification Effectiveness Time, Borrower may instruct the Administrative Agent upon not less than four (4) Business Days’ notice to disburse the Required Principal Payment from the Sweep Account to the Administrative Agent for distribution to the Lenders holding an interest in Note A, and in proportion to their respective interests therein, to reduce the outstanding balance of Note A, in which event Borrower shall pay any Breakage Costs described in Section 2.2.3(g) in connection therewith. From time to time after the Modification Effectiveness Time, at Borrower’s request the Administrative Agent agrees to provide Borrower with an estimate of any Breakage Costs described in Section 2.2.3(g) that would be payable by Borrower in connection with any such prepayment as of any given date. If the Required Principal Payment has not been disbursed to prepay a portion of the outstanding balance of Note A before August 9, 2012, then on August 9, 2012, and without further instructions from Borrower, it shall be automatically disbursed to the Administrative Agent for distribution to the Lenders holding an interest in Note A, and in proportion to their respective interests therein, to reduce the outstanding balance of Note A. In connection with any such prepayment on August 9, 2012, Borrower shall not be required to pay any Breakage Costs described in Section 2.2.3(g).

(rr)    The following sentence is hereby added at the end of Section 2.4.2 of the Loan Agreement:

Following the Modification Effectiveness Time, while a Cash Trap Period exists, on each Monthly Payment Date, all amounts in the Sweep Account shall be used to prepay the outstanding principal amount of the Notes (with the first such payments to be applied to the principal balance of Note A until the principal balance of Note A has been paid in full, and then applied to Note B), without any prepayment premium. It is understood and agreed that, as a material inducement to the Administrative Agent and the Lenders to agree to the modifications of the Loan Agreement and the Loan Documents that are provided for in the Modification Agreement, Borrower has elected to make the principal payment provided for in Section 1(b) of the Modification Agreement, as well as the principal payments that will result from the application of the funds in the Sweep Account to the principal balance of Notes A and B as provided for herein. Borrower hereby confirms that each of principal payments made pursuant to the foregoing provisions are and shall be principal payments which the Borrower has

elected (and is obligated) to make, and Borrower’s election and obligation to make such principal payments is and shall be absolute, unconditional and irrevocable. No prepayment premium shall apply to, nor shall any requirement for prior notice of such prepayments or for any minimum amount of prepayments be applicable to, any of the principal payments provided for in Section 1(b) of the Modification Agreement or that will result from the application of the funds in the Sweep Account to the principal balance of Notes A and B as provided for herein. Provided that no Event of Default exists, if the amount of funds that would otherwise be required under this Agreement to be applied from the Sweep Account to repay the principal balance of the Loans on any Monthly Payment Date exceeds the Projected Principal Pay-Down Amount for such Monthly Payment Date, as determined pursuant to Section 2.2.3(b), then (i) only the portion of such funds equal to the Projected Principal Pay-Down Amount shall be applied to repay the principal balance of the Loans on such Monthly Payment Date; and (ii) such excess funds shall be deposited into the Deposit Account on the Business Day following such Monthly Payment Date, and available for allocation in accordance with the Cash Management Agreement on the next Monthly Payment Date.

(ss)    The text of Section 2.4.3 of the Loan Agreement is hereby deleted and replaced with the following:

If, while an Event of Default exists, but prior to October 1, 2013, payment of all or any part of the principal of the Loan is tendered by Borrower (which tender Lender may reject to the extent permitted under applicable Legal Requirements), a purchaser at foreclosure or any other Person, such tender shall be deemed an attempt to circumvent the prohibition against prepayment set forth in Section 2.4.1 and Borrower, such purchaser at foreclosure or other Person shall pay (i) all accrued and unpaid interest calculated at the Applicable Interest Rate on the amount of principal being paid, (ii) the Interest Shortfall, if applicable, with respect to the principal amount being paid, (iii) Breakage Costs, if any, without duplication of any sums paid pursuant to the preceding clause (ii), (iv) a prepayment premium described in Section 2.4.1(d) calculated with respect to the amount of principal being paid, and (v) all other sums due under this Agreement (including Section 2.3.3), the Notes or the other Loan Documents in connection with a partial or total prepayment.

(yy)    Section 4.1.9 of the Loan Agreement is hereby modified by adding the following subsection at the end thereof:

(d)    In connection with any new Lease, if a tenant under such Lease requires that it be given a right of offset against rentals payable by it thereunder, for unpaid leasing commissions, tenant improvement or other leasing costs, the Administrative Agent will agree to recognize such offset right in a subordination, non-disturbance and attornment agreement in favor of such tenant to the extent the form of such subordination, non-disturbance and attornment agreement is reasonably acceptable to the Administrative Agent and there are funds on deposit in the Rollover Account which are sufficient to cover the maximum amount of rentals that may be offset on account of unpaid leasing commissions, tenant improvement or other leasing costs; provided that, in the case any such offset rights are recognized, a portion of the funds on deposit in the Rollover Account, in an amount equal to the maximum amount of rentals that may be offset by such tenant on account of such unpaid leasing commissions, tenant improvement or other leasing costs shall be earmarked as available to be disbursed to Borrower for no purpose other than the leasing commissions, tenant improvement or other leasing costs with respect to which such rights of offset may be exercised. If, while any Event of Default exists, the Administrative Agent shall direct any portion of the funds in the Rollover Account that have been earmarked for such leasing commissions, tenant improvement or other leasing costs to be released to it, or otherwise exercises any rights and remedies with respect to such portion of such funds in any manner that results in the remittance to the Administrative Agent of such portion of such funds, it is understood and agreed that no portion of the Debt shall be deemed to have been repaid with such funds, and that the Administrative Agent may continue to hold such funds, and apply them towards the funding of the leasing commissions, tenant improvement or other leasing costs with respect to which such portion of such funds has been earmarked, unless the Administrative Agent expressly otherwise elects in writing. The Administrative Agent shall be authorized to exercise all available rights and remedies with respect to such portion of the funds, and to apply any leasing commissions, tenant improvement or other leasing costs with respect to which such portion of such funds has been earmarked. Nothing contained in this Section 4.1.9, however, shall be deemed or construed to limit a tenant’s rights to offsets for any leasing commissions, tenant improvement or other leasing costs that are recognized by the Administrative Agent pursuant to a subordination,

non-disturbance and attornment agreement entered into by the Administrative Agent in accordance with the provisions hereof.

(zz)    A new Section 4.1.23 is hereby added to the Loan Agreement as follows:

In addition, upon the Administrative Agent’s request therefore, Borrower shall also cause to be delivered to the Administrative Agent (A) such appropriate documentation as may be reasonably requested by the Administrative Agent reflecting the identity, organization, good standing, tax status and financial standing of the Approved Transferee and any Person Controlling such Approved Transferee and of the entities that will hold, after such Transfer, twenty percent (20%) or more of the direct or indirect interests in Borrower, if any, and (B) such other documents as the Administrative Agent or any Lender may reasonably require for the purpose of undertaking such background checks and satisfying such “know-your-customer” and “anti-money laundering” requirements with respect to such Approved Transferee and any Person Controlling such Approved Transferee as are required by applicable law; provided, however, that in no event shall the foregoing be deemed to require Borrower to deliver any such documentation with respect to a shareholder of the Approved Transferee if the Approved Transferee is an entity whose common stock is listed on the New York Stock Exchange or another nationally recognized stock exchange (except for a shareholder whose holdings in the Approved Transferee would involve twenty percent (20%) or more of the direct or indirect interests in Borrower);

(iii)    as of the consummation of the Permitted Corporate Transfer Transaction, Borrower shall deliver its written certification to the Administrative Agent and Lenders to the effect that, after giving effect to such Permitted Corporate Transfer Transaction, no natural person owns, directly or indirectly, more than 25% of the capital interest and/or voting interests of Borrower, except as disclosed in such certification;

(iv)    no monetary default and no Event of Default shall have occurred and remain uncured or unwaived at the time of or shall result from such Permitted Corporate Transfer Transaction;

(v)    Borrower shall at all times continue to be a single member limited liability company that complies with the requirements of Section 3.1.24;

(vi)    after giving effect to such Permitted Corporate Transfer Transaction, (i) the REIT (or, if applicable, the Person that is the survivor of a merger or consolidation with the REIT or that acquires all of the partnership interests of the Sponsor that are owned by the REIT) shall continue to be the sole general partner of the Sponsor, (ii) the Sponsor (or, if applicable, the Person that is the survivor of a merger or consolidation with the Sponsor) shall continue to Control Borrower, (iii) subject to the rights of any approved property manager under any approved management agreement with respect to the Property, the Sponsor (or, if applicable, the Person that is the survivor of a merger or consolidation with the Sponsor) shall continue to manage and direct the day-to-day operations of the Property, and (iv) Borrower shall continue to own the Property;

(vii)    the financial standing and creditworthiness of the Guarantor (determined immediately prior to giving effect to such Permitted Corporate Transfer Transaction) shall not be materially adversely affected as a result of such Permitted Corporate Transfer Transaction (and any transactions occurring concurrently therewith), unless: (i) a replacement guarantor that is not a Prohibited Person, with financial standing and creditworthiness at least equivalent to the financial standing and creditworthiness of the Guarantor (determined immediately prior to giving effect to such Permitted Corporate Transfer Transaction), shall assume all of the obligations of the Guarantor under the Recourse Guarantee pursuant to an assumption agreement that is in form and substance reasonably satisfactory to the Administrative Agent, (ii) concurrently with the delivery of such assumption agreement, the replacement guarantor shall deliver to the Administrative Agent true and correct certified copies of the organizational documents for such replacement guarantor and copies of the resolutions or other corporate or organizational authorizations that authorize such replacement guarantor to execute and deliver such assumption agreement, and (iii) concurrently with the delivery of such assumption agreement, counsel to such replacement guarantor shall deliver to the Administrative Agent an opinion in form and substance reasonably satisfactory to the Administrative Agent as to the due authorization, execution, delivery and enforceability of such assumption agreement. For purposes of the foregoing, the financial standing and creditworthiness of the Guarantor shall not be deemed materially adversely affected unless the capital/statutory surplus or shareholder’s (or owner’s) equity, as the case may be, of Guarantor as a result of such Permitted Corporate Transfer Transaction (and any transactions occurring concurrently therewith) is less than ninety percent (90%) of the Guarantor’s capital/statutory

surplus or shareholder’s (or owner’s) equity, as the case may be, immediately prior to giving effect to such Permitted Corporate Transfer Transaction; and

(viii)    Borrower shall reimburse the Administrative Agent for all reasonable out-of-pocket costs and expenses incurred by the Administrative Agent (including reasonable fees and expenses of legal counsel) in connection with such Permitted Corporate Transfer Transaction.

Notwithstanding anything to the contrary in this Section 8.1(j), if as a result of a transaction that would otherwise be a Permitted Corporate Transfer Transaction (an “Otherwise Permitted Corporate Transfer Transaction”), a Person’s acquisition of direct or indirect ownership interests in or control of Borrower would cause any exposure, lending or loan-to-one-borrower (or borrower group) or similar limits imposed pursuant to any law, rule, order, regulation, judgment, injunction, directive or regulatory guideline of any governmental authority (whether foreign, domestic or supranational (including, without limitation, the European Union)) applicable to any Lender in relation to such Person to be exceeded, or any other law, rule, order or regulation, judgment, injunction, directive or regulatory guideline of any governmental authority (whether foreign, domestic or supranational (including, without limitation, the European Union)) applicable to any Lender in relation to such Person to be violated (such limit, a “Lending Limit,” such Person, a “Limiting Purchaser,” and any such Lender, a “Limit-Constrained Lender”), then such Otherwise Permitted Corporate Transfer Transaction shall not be consummated unless such Limit-Constrained Lender’s prior written approval (or deemed approval, as hereinafter provided) of such Otherwise Permitted Corporate Transfer Transaction shall have been obtained.

The Administrative Agent shall promptly deliver to each Lender a copy of the written notice delivered to the Administrative Agent by Borrower of such Otherwise Permitted Corporate Transfer Transaction pursuant to clause (ii) above (Borrower’s notice is referred to herein as the “Transaction Notice” with respect to such Otherwise Permitted Corporate Transfer Transaction).

If a Lender has not, within five (5) Business Days after its receipt of the Transaction Notice from the Administrative Agent, delivered written notice to Borrower and the Administrative Agent stating whether or not such Lender is a Limit-Constrained Lender in relation to the Otherwise Permitted Corporate Transfer Transaction described in the Transaction Notice and certifying, if such notice states that such Lender is a Limit-Constrained Lender in relation to such Otherwise Permitted Corporate Transfer Transaction, as to the Lending Limit to which such Limit-Constrained Lender is subject in relation to such Otherwise Permitted Corporate Transfer Transaction (such notice is referred to herein as a “Limit-Constrained Lender Identification Notice”), then Borrower may send a written request to the Administrative Agent and such Lender

which shall reference this Agreement and include in bold lettering the following statement: “A ‘LIMIT-CONSTRAINED LENDER IDENTIFICATION NOTICE’ FROM ________________ [INSERT HERE THE NAME OF THE NON-RESPONDING LENDER], IN WHICH IT IDENTIFIES WHETHER OR NOT IT IS A LIMIT-CONSTRAINED LENDER IN RELATION TO THE OTHERWISE PERMITTED CORPORATE TRANSFER TRANSACTION DESCRIBED IN THE TRANSACTION NOTICE DATED ________, 201_, IS REQUESTED WITHIN FIVE (5) BUSINESS DAYS AFTER _______________’S RECEIPT OF THIS NOTICE. FAILURE OF ______________ TO PROVIDE SUCH LIMIT-CONSTRAINED LENDER IDENTIFICATION NOTICE WITHIN SUCH FIVE (5) BUSINESS DAY PERIOD SHALL RESULT IN SUCH LENDER BEING DEEMED NOT TO BE A LIMIT-CONSTRAINED LENDER IN RELATION TO THE OTHERWISE PERMITTED CORPORATE TRANSFER TRANSACTION DESCRIBED IN THE TRANSACTION NOTICE DATED ________, 201_.” If any Lender fails to provide a Limit-Constrained Lender Identification Notice to Borrower and the Administrative Agent within five (5) Business Days after its receipt of the foregoing notice from Borrower, then such Lender shall be deemed not to be a Limit-Constrained Lender with respect to the Otherwise Permitted Corporate Transfer Transaction described in the Transaction Notice.

If, within ten (10) Business Days after the delivery by any Limit-Constrained Lender of its Limit-Constrained Lender Identification Notice to Borrower and the Administrative Agent, such Limit-Constrained Lender has not delivered written notice to Borrower and the Administrative Agent as to whether it approves or disapproves of the Otherwise Permitted Corporate Transfer Transaction described in the Transaction Notice (such notice is referred to herein as a “Lending Limit Response Notice”), then Borrower may send a written request to the Administrative Agent and such Limit-Constrained Lender which shall reference this Agreement and include in bold lettering the following statement: “A ‘LENDING LIMIT RESPONSE NOTICE’ FROM ________________ [INSERT HERE THE NAME OF THE LIMIT-CONSTRAINED LENDER], IN WHICH IT APPROVES OR DISAPPROVES OF THE OTHERWISE PERMITTED CORPORATE TRANSFER TRANSACTION DESCRIBED IN THE TRANSACTION NOTICE DATED ________, 201_, IS REQUESTED WITHIN FIVE (5) BUSINESS DAYS AFTER _______________’S RECEIPT OF THIS NOTICE. FAILURE OF ______________ TO PROVIDE SUCH LENDING LIMIT RESPONSE NOTICE WITHIN SUCH FIVE (5) BUSINESS DAY PERIOD SHALL RESULT IN THE DEEMED APPROVAL BY ______________ OF THE OTHERWISE PERMITTED CORPORATE TRANSFER TRANSACTION DESCRIBED IN THE TRANSACTION NOTICE DATED ________, 201_.” If any Lender fails to provide a Lending Limit Response Notice to Borrower and the Administrative Agent within five (5) Business Days after its receipt of the foregoing notice from Borrower, then such Lender shall be

deemed to have approved of the Otherwise Permitted Corporate Transfer Transaction described in the Transaction Notice, notwithstanding any Lending Limit applicable to it.

If a Lender timely provides a Limit-Constrained Lender Identification Notice and a Lending Limit Response Notice to Borrower and the Administrative Agent, and in such Lending Limit Response Notice states that it does not approve of such Otherwise Permitted Corporate Transfer Transaction, then Borrower may at its option, upon not less than three (3) Business Days’ notice (and in all events either prior to or concurrently with the consummation of the Otherwise Permitted Corporate Transfer Transaction), require such Limit-Constrained Lender to, and such Limit-Constrained Lender shall, transfer all of its right, title and interest under the Loan Agreement and such Limit-Constrained Lender’s Note to a Borrower-Affiliated Purchaser (as hereinafter defined) or to any Eligible Assignee or other prospective assignee selected by Borrower or such Limiting Purchaser that is not a Prohibited Person and is satisfactory to the Administrative Agent (provided that the Administrative Agent shall not unreasonably withhold its consent to a proposed transfer of such right, title and interest to an Eligible Assignee that is not a Prohibited Person), provided that (i) such Borrower-Affiliated Purchaser, such Eligible Assignee or such other approved assignee shall not be a Prohibited Person and shall assume all of the obligations of such Limit-Constrained Lender under the Loan Documents and under any separate agreement among the Lenders, and purchases all of such Limit-Constrained Lender’s loan(s) for consideration equal to the aggregate outstanding principal amount of such Limit-Constrained Lender’s loan(s), together with interest thereon to the date of such purchase (to the extent not then paid by Borrower), and (ii) such Limit-Constrained Lender receives, in addition to such consideration, and either from Borrower or from such Borrower-Affiliated- Purchaser, such Eligible Assignee or such other approved assignee, all other amounts then accrued and payable on such Limit Constrained Lender’s loan(s) as of the date of such transfer and all Breakage Costs and prepayment premiums (but not any amounts on account of future interest to be accrued prior to the end of the applicable Interest Period in which such purchase occurs) that would be payable pursuant to the Amended Loan Documents as if such Limit-Constrained Lender’s Loans were being prepaid in full on such date.

For purposes of this Section 8.1(j) and Section 8.1(k), a “Borrower-Affiliated Purchaser” shall mean any Person that complies with the covenants described in clause (1) of the immediately preceding paragraph and is an Affiliate of Borrower or an Affiliate of the Limited Purchaser (where for purposes of this definition, the definition of “Control” for determination of an Affiliate shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of an entity, whether through the ability to exercise voting power, by contract or otherwise (and “Controlled by,” “Controlling” and “under Common Control with” shall have the respective correlative meaning thereto), or the ownership, directly or

indirectly, ten percent (10%) or more of the equity interests of the affiliated Person).

Prior to the consummation of the transfer of any interest to a Borrower-Affiliated Purchaser, and as a condition thereto, information comparable to that required in the second sentence of clause (b) of this Section 8.1(j) shall have been provided with respect to such Borrower-Affiliated Purchaser to the Administrative Agent, together with all tax forms applicable to withholding, administrative details, and other information customarily delivered to the Administrative Agent in connection with the transfer by a Lender of any interest in the Loan, and the Administrative Agent shall have completed all background checks and “know your customer” and “anti-money laundering” requirements applicable to such transferee.

“Eligibility Requirements” shall mean, with respect to any Person, that such Person (i) has total assets (in name or under management) in excess of $500,000,000 and (except with respect to a pension advisory firm, asset manager or similar fiduciary) a capital/statutory surplus or shareholder’s (or owner’s) equity of at least $250,000,000 and (ii) is regularly engaged in the business of owning and operating commercial real estate properties of the type, size and quality comparable to the Property (or shall have engaged a management and/or leasing agent that has such experience and such management and/or leasing agent is reasonably acceptable to the Administrative Agent).

3.    Cash Management. Upon the Modification Effectiveness Time, the Original Cash Management Agreement shall be replaced with the Cash Management Agreement, which shall provide that the Agent shall (subject to the Administrative Agent’s rights under Article V of the Cash Management Agreement while any Event of Default exists), in accordance with directions provided by the Administrative Agent to the Agent, which directions the Administrative Agent may provide in the Administrative Agent’s discretion while any Event of Default exists, allocate all available funds on deposit in the Deposit Account on every Business

Day of each calendar month to the following Reserve Funds, in the following amounts and order of priority (capitalized terms used in this Section 3 but not defined in the Loan Agreement, as amended hereby, shall have the meanings set forth in the Cash Management Agreement), it being understood that if such allocation is occurring on a Monthly Payment Date, the references in clauses (i), (ii) and (iv) below to the “next” Monthly Payment Date shall mean the Monthly Payment Date on which such allocation is occurring):

(i)    First, funds sufficient to pay the Monthly Tax Amount due on the next Monthly Payment Date shall be deposited into the Tax Account;

(ii)    Second, funds sufficient to pay the Monthly Insurance Amount due on the next Monthly Payment Date shall be deposited into the Insurance Account;

4.    Reaffirmation and Waiver.

(a)    Borrower hereby (i) reaffirms, ratifies, confirms, and acknowledges its obligations and waivers under the Notes, the Loan Agreement, and all the other Loan Documents as of the date hereof and after giving effect to this Amendment and the actions contemplated thereby, and agrees to continue to be bound thereby and perform thereunder after giving effect to this Amendment and the actions contemplated thereby, (ii) agrees and acknowledges that all such Loan Documents and all of Borrower’s obligations and waivers thereunder are and remain in full force and effect and, except as expressly provided herein, have not been modified. Except as expressly provided herein, nothing in this Amendment shall alter or affect any provision, condition, or covenant contained in the Loan Agreement or other Loan Documents or affect or impair any rights, powers or remedies of the Administrative Agent or the Lenders, it being the intent of the parties hereto that the provisions of the Loan Agreement and other Loan Documents shall continue in full force and effect except as expressly modified hereby.

(b)    Concurrently herewith, Guarantor is executing and delivering to the Administrative Agent the Guarantor Reaffirmation Agreement referred to in Section 1(a)(ii) above.

5.    Representations and Warranties. Borrower hereby represents and warrants to the Administrative Agent and the Lenders as of the date hereof and as of the Modification Effectiveness Time as follows:

(a)    Borrower has the power and authority to enter into this Amendment and the documents and instruments to be delivered by Borrower pursuant hereto and to perform its obligations hereunder and thereunder, and Borrower’s execution and delivery of this Amendment and the documents and instruments to be delivered by Borrower pursuant hereto have been duly authorized by all necessary organizational action. No consent, approval, authorization or order of any court or Governmental Authority is required in connection with the execution, delivery or performance by Borrower of this Amendment or any document or instrument to be delivered by Borrower pursuant hereto, other than those which have been obtained by Borrower. This Amendment and the documents and instruments to be delivered by Borrower pursuant hereto have been duly executed and delivered, and constitute the legal, valid and binding obligation of

Borrower, enforceable against Borrower in accordance with their respective terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally, or by equitable principles relating to enforceability.

(b)    As of the Modification Effectiveness Time, no Event of Default or, to Borrower’s knowledge, Potential Default exists.

(c)    As of the date hereof and immediately after giving effect to this Amendment and the actions contemplated thereby, Borrower certifies, represents, warrants and acknowledges that it has no claims, offsets or defenses with respect to the payment of sums due, the performance of any other obligations under or the effectiveness of any waivers set forth in the Loan Agreement, the Notes or any other Loan Document. Without limiting the foregoing, immediately prior to the Modification Effectiveness Time, Borrower hereby confirms that Loans in the aggregate amount of $400,000,000 are outstanding and that interest on the Loans at the Applicable Interest Rate has been paid through (but not including) June 9, 2012.

(d)    Borrower represents, warrants and acknowledges that it has performed all of its obligations under the Latham & Watkins U.S. Bank Tower Lease Takeover Agreement, that no other obligations remain outstanding under the Latham & Watkins U.S. Bank Tower Lease Takeover Agreement and that the Latham & Watkins U.S. Bank Tower Lease Takeover Agreement has terminated by its own terms.

(e)    As of the date hereof and immediately after giving effect to this Amendment and the actions contemplated thereby, all representations and warranties made and given by Borrower in the Loan Documents are true, accurate and correct in all material respects as if made on the date hereof.

(f)    No condemnation or adverse zoning or usage change has occurred or has been proposed with respect to the Property which would have a Material Adverse Effect, and no Legal Requirements have been enacted or adopted, and no proceeding, litigation or action has been commenced or threatened by any Person or Governmental Authority, that would have a Material Adverse Effect.

6.    Release and Covenant Not to Sue. In consideration of the Administrative Agent’s and each Lender’s execution and delivery of this Amendment, Borrower hereby remises, releases, acquits, satisfies and forever discharges the Administrative Agent and each of the Lenders from any and all manner of debts, accountings, bonds, warranties, representations, covenants, promises, contracts, controversies, agreements, liabilities, obligations, expenses, damages, judgments, executions, actions, claims, demands and causes of action of any nature whatsoever, at law or in equity, known or unknown, either now accrued or subsequently maturing, which Borrower now has or hereafter can, shall or may have by reason of any matter, cause or thing, from the beginning of the world to and including the date of this Amendment arising out of or relating to (a) the Loans, including, but not limited to, the administration and funding of the Loans, (b) the Loan Documents, and (c) any other agreement or transaction between Borrower and any of Lenders relating to the matters described in (a) and (b) above (collectively, the “Released Claims”). Borrower hereby covenants and agrees never to institute or cause to be instituted or continue prosecution of any suit or other form of action or proceeding

of any kind or nature whatsoever against any of the Lenders by reason of or in connection with any of the foregoing matters, claims or causes of action. Borrower acknowledges and agrees that it may hereafter discover facts relating to the Released Claims released herein in addition to or different from those which it believed to be true as of the date hereof, which if known by it might have materially affected its willingness to enter into this settlement on the terms herein, and further understand, acknowledge and agree that it is its intention that the Released Claims released herein shall nonetheless be deemed to be fully, finally, and forever settled and released as of the date hereof, without regard to the subsequent discovery or existence of such additional or different facts. Borrower acknowledges that it has received competent and independent legal advice with respect to the meaning and effect of this express waiver of unknown claims.

Without limiting the generality of the forgoing, Borrower hereby acknowledges that it is familiar with and knowingly and intentionally waives all rights under California Civil Code Section 1542, or any comparable statute which may be applicable. California Civil Code Section 1542 provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Notwithstanding the provisions of California Civil Code Section 1542, and for the purpose of implementing a full and complete release and discharge of the Parties, Borrower hereby knowingly and intentionally waives and relinquishes all rights and benefits which it has or may have under California Civil Code Section 1542 or the law of any other state or jurisdiction to the same or similar effect, to the full extent that it may lawfully waive all such rights and benefits relating to the Released Claims and that this Section 5 expressly contemplates the extinguishment of all such claims.

Borrower hereby represents and warrants to the Lenders that it has not heretofore assigned, transferred or encumbered in any manner, including by subrogation, operation of law or otherwise, or purported to assign, transfer or encumber (and covenants that such it will not, except as provided herein, assign, transfer, encumber or attempt to assign, transfer or encumber), to any Person, any of the Released Claims.

Borrower hereby represents and warrants to the Administrative Agent and the Lenders that it has had a full and complete opportunity to investigate, and has, in fact, investigated, all facts and circumstances pertaining to the Released Claims and any and all additional relevant matters, as it deems necessary; that it is relying solely upon its own investigation in executing the release set forth in Section 5; and that it has not relied upon any statement, representation, promise or agreement of any other Person or any representative or attorney of any other Person in executing said release. Without limiting the generality of the foregoing, Borrower acknowledges that (a) it understands the terms and consequences of making said release; (b) it has been represented in the preparation, negotiation, and execution of this Amendment by legal counsel of its own choice; (c) is fully aware of the legal and binding effect of said release; and (d) has executed this

Amendment voluntarily and without any duress or undue influence on the part of any of the Release Parties or any third party.

7.    Miscellaneous.

(a)    Controlling Provisions. In the event of any inconsistencies between the provisions of this Amendment and the provisions of any other Loan Document, the provisions of this Amendment shall govern and prevail. Except as expressly modified by this Amendment, the Loan Documents shall not be modified and shall remain in full force and effect.

(b)    Further Assurances. At the Administrative Agent’s request, Borrower shall promptly execute any other document or instrument and/or seek any consent or agreement from any third party that the Administrative Agent reasonably determines is necessary to evidence or further, or is otherwise relevant to, the intent of the parties, as set forth in this Amendment, provided, the same shall not result in a decrease of the rights of Borrower or result in an increase in Borrower’s obligations under the Loan Documents. At the Administrative Agent’s request, Borrower shall promptly cause Guarantor to execute any other document or instrument and/or diligently seek any consent or agreement from any third party that the Administrative Agent reasonably determines is necessary to evidence or further, or is otherwise relevant to, the intent of the parties, as set forth in this Amendment, provided the same shall not result in a decrease of the rights of Guarantor or result in an increase in Guarantor’s obligations under the Loan Documents.

(c)    Counterparts. This Amendment may be executed by one or more of the parties to this Amendment in any number of separate counterparts, each of which, when so executed, shall be deemed an original, and all of said counterparts taken together shall be deemed to constitute but one and the same instrument.

(d)    Entire Agreement. This Amendment is a Loan Document. This Amendment, together with the other Loan Documents, sets forth the entire agreement and understanding among Borrower, the Administrative Agent and the Lenders, and supersedes all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof. This Amendment shall not prejudice any rights or remedies of the Administrative Agent or the Lenders under the Loan Documents. The Administrative Agent and each Lender reserve, without limitation, all rights which each has against any indemnitor, guarantor or endorser of the Notes. Nothing in this Amendment shall impair the lien of the Mortgage, which after giving effect hereto remains a deed of trust, security agreement and fixture filing creating a first priority, perfected lien and security interest, with power of sale, upon the Property as described therein

(e)    GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(f)    No Third Parties Benefited. This Amendment is made and entered into for the sole protection and legal benefit of Borrower, the Administrative Agent, the Lenders and their permitted successors and assigns, and no other Person shall be a direct or indirect legal

beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Amendment or any of the other Loan Documents.
