Each Issuer’s obligation to effect such issuance, continuance or Amendment shall be subject to the following conditions: (A) prior satisfaction by the Applicant of its obligations set forth in Section 5(a), (B) payment in full of the fees and expenses described in Section 8 hereof that are due and payable on or prior to the date of issuance (or continuance) or amendment of such Letter of Credit and (C) all representations and warranties contained in this Agreement being true and correct in all material respects as of the date of such issuance, continuance or Amendment, except to the extent such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall be true and correct in all material respects on and as of such earlier date (provided that, in each case, if any representation or warranty is already qualified by materiality, such representation or warranty must be true and correct in all respects) and that no Event of Default hereunder has occurred as of the date such Letter of Credit is issued (or continued) or amended, as applicable. Each issuance, continuance or Amendment of a Letter of Credit shall be deemed to constitute a representation and warranty by the Applicant on the date of such issuance, continuance or Amendment as to the matters specified in the preceding subclause (C). No Issuer shall be required or permitted to issue, continue, amend or renew any Letter of Credit (except to reduce the face amount thereof) if immediately after giving effect thereto, (x) the aggregate L/C Outstandings with respect to all Letters of Credit would exceed the Aggregate Availability or (y) the aggregate L/C Outstandings with respect to all Letters of Credit issued by such Issuer would exceed such Issuer’s Commitment. For the avoidance of doubt, no Issuer will be required to provide documentary, trade or commercial letters of credit without its prior written consent (in each Issuer’s sole discretion). However, documentary Letters of Credit calling for invoices or copies of invoices may be allowed, in each Issuer’s sole discretion.

(b)Notwithstanding the foregoing, no Issuer is under any obligation to issue any Letter of Credit or Amendment thereto if: (i) at the time of such issuance any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms enjoin or restrain such Issuer from issuing such Letter of Credit or any requirement of law applicable to such Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuer shall prohibit, or request that such Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuer with respect to such Letter of Credit any restriction or reserve or capital requirement (for which such Issuer is not otherwise compensated hereunder) not in effect with respect to such Issuer on the Effective Date, or any unreimbursed loss, cost or expense that was not applicable or in effect with respect to such Issuer as of the Effective Date and which such Issuer reasonably and in good faith deems material to it, (ii) the proposed beneficiary is a Sanctioned Person or (iii) such issuance would violate any policies of such Issuer applicable to the issuance of letters of credit generally.

(c)Each Issuer, in its sole discretion, may issue (or continue) any Letter of Credit through one or more of its branches or affiliates.

(d)Notwithstanding anything to the contrary contained herein, in no event may a Request or Amendment Request be submitted to any Issuer, and no Letter of Credit (or Amendment thereto) shall be issued or continued, after the expiration of the Issuance Period unless expressly consented to in writing by the applicable Issuer. Furthermore, no Letter of Credit shall have an expiration date later than the earlier of (i) the date one year after the issuance of such Letter of Credit and (ii) the date that is five (5) Business Days prior to the last day of the Issuance Period; provided that a Letter of Credit may, upon the request of the Applicant, include a provision whereby such Letter of Credit shall be renewed automatically for additional consecutive periods of 12 months or less (but not beyond the date that is five (5) Business Days prior to the last day of the Issuance Period) unless the Issuer notifies the beneficiary thereof at least 30 days (or within such longer period as specified in such Letter of Credit) (the date on which any such notice is due, the “L/C Roll Determination Date”) prior to the then-applicable expiration date that such Letter of Credit will not be renewed. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Applicant to, or entered into by the Applicant with, an Issuer relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(e)Unless otherwise expressly agreed by the applicable Issuer and the Applicant (including any such agreement applicable to an existing Letter of Credit), when a Letter of Credit is issued, the Letter of Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication Number 600 (“UCP 600”) and matters not governed by UCP 600 shall be governed and construed in accordance with the laws of New York.

(f)It is understood that (i) no Issuer shall be responsible for any failure by any other Issuer to perform its obligation to issue any Letter of Credit hereunder; nor shall any Commitment of any Issuer be increased or decreased as a result of any failure by any other Issuer to perform its obligation to issue any Letter of Credit hereunder, (ii) no failure by any Issuer to perform its obligation to issue any Letter of Credit hereunder shall excuse any other Issuer from its obligation to issue any Letter of Credit hereunder, and (iii) the obligations of each Issuer hereunder shall be several, not joint and several.

(g)As of the Business Day immediately preceding the requested issuance date of any Letter of Credit, the Administrative Agent shall determine the Total Unutilized L/C Commitment and Aggregate Availability and notify each Issuer thereof.

(h)Each Issuer shall promptly (i) notify the Administrative Agent in writing of the Stated Amount and expiry date of each Letter of Credit issued by it and (ii) provide the pertinent details of such Letter of Credit or amendment to the Administrative Agent. Each Issuer shall provide to the Administrative Agent, as per Administrative Agent’s request, an activity report in the form of Exhibit C attached hereto.

4.Reimbursement.

(a)The Applicant shall reimburse the applicable Issuer for the amount of any drawing honored under a Letter of Credit and paid by such Issuer (the “L/C Reimbursement Amount”). The Applicant shall reimburse the applicable Issuer under this Section 4(a) in immediately available funds (i) no later than 3:00 p.m. on the day (which shall be a Business Day) on which payment is made by such Issuer under a Letter of Credit; provided that the Issuer notifies the Applicant by 12:00 p.m. on such date that such Issuer has made such payment under such Letter of Credit and the full amount of the L/C Reimbursement Amount, or (ii) if the Issuer notifies the Applicant after 12:00 p.m. on the date of such payment, by 11:00 a.m. on the next Business Day following receipt of such notice by the Applicant; provided that the failure of the Issuer to so notify the Applicant, and any delay in so notifying the Applicant, shall not relieve, limit or otherwise affect any obligation of the Applicant under this Agreement or any related document. Each Issuer shall simultaneously provide a copy of each reimbursement notice provided to the Applicant under this Section 4(a) to the Administrative Agent and the Collateral Agent.

(b)If the Applicant fails to reimburse the Issuer on the date and at the time required in accordance with Section 4(a), the Collateral Agent shall, following notice to the Collateral Agent from the applicable Issuer and upon not less than one (1) Business Days’ prior written notice from the Collateral Agent to the Applicant, withdraw from the Constellation Collateral Accounts (to the extent established) an amount of cash and/or Eligible Treasury Assets (in accordance with Section 6(d)) equal to the L/C Reimbursement Amount due to such Issuer and shall apply such amounts to repay such L/C Reimbursement Amount; provided that if there is not a sufficient amount of cash and/or Eligible Treasury Assets on deposit in or credited to the Constellation Collateral Accounts on any such date, the Collateral Agent shall withdraw from the Trust Collateral Account (in accordance with Section 6(d)) an amount of Eligible Treasury Assets equal to the amount of such shortfall and shall apply such amounts to repay the L/C Reimbursement Amount due to such Issuer. The Applicant (i) authorizes and directs the Collateral Agent to charge the Constellation Collateral Accounts (A) upon and after the drawing of any Letter of Credit for the full amount of the L/C Reimbursement Amount, to the extent the Applicant has failed to reimburse the applicable Issuer in accordance with Section 4(a), and (B) from time to time for any other Obligations not paid within five (5) Business Days after the due date thereof and (ii) confirms that it has irrevocably directed and caused the Trust to authorize and direct the Collateral Agent to charge the Trust Collateral Account (A) upon and after the drawing of any Letter of Credit for the full amount of the L/C Reimbursement Amount, to the extent the Applicant has failed to reimburse the applicable Issuer in

accordance with Section 4(a), and (B) from time to time for any other Obligations not paid within five (5) Business Days after the due date thereof.

(c)The Applicant shall pay to each Issuer, promptly upon demand, all Issuer Costs as more specifically set forth in Section 8(a).

5.Covenants.

(a)The Applicant will, and will direct the Trust in accordance with the Facility Agreement to, enter into the Pledge Agreement with the Securities Intermediary and the Collateral Agent, pursuant to which the Applicant and the Trust will grant to the Collateral Agent a Lien on the Collateral Accounts to secure the Obligations owed to the Secured Parties and the Applicant will, and will direct the Trust to, enter into an amendment to the Pledge Agreement, if necessary, to perfect the Lien granted to the Collateral Agent upon the establishment of any Collateral Accounts after the date hereof. Prior to the issuance (or continuance) by any Issuer of any Letter of Credit (or any Amendment thereto) hereunder and as a condition precedent thereto, the Applicant shall confirm that the sum of (i) the aggregate Net Asset Value of cash and Eligible Treasury Assets deposited in or credited to the Constellation Collateral Accounts and (ii) the aggregate Net Asset Value of Eligible Treasury Assets credited to the Trust Collateral Account (such aggregate amount, the “Aggregate Collateral Amount”) is equal to or greater than the Minimum Collateral Base. In the event the Aggregate Collateral Amount exceeds the Minimum Collateral Base, upon the written request of Applicant, any such excess amount, as certified by the Applicant, shall be released from any Lien created under the Pledge Agreement and the Applicant shall be permitted to withdraw such excess funds from the Constellation Collateral Accounts, and shall be permitted to withdraw such excess assets from the Trust Collateral Account in connection with any permitted voluntary or mandatory exercise of issuance rights under the Facility Agreement (provided that any such release of Lien with respect to, and withdrawal of, Eligible Treasury Assets from the Trust Collateral Account shall be made pro rata across each interest and principal STRIP as determined in accordance with the Pledge Agreement), so long as no Event of Default has occurred and is continuing or would result therefrom; provided, further, that, in the case of any cancellation, termination or expiration of any Letter of Credit in connection therewith, the applicable Issuer shall have received reasonably satisfactory evidence of such cancellation, termination or expiration. The Applicant agrees to use commercially reasonable efforts to return such expired, terminated or cancelled Letter of Credit to the applicable Issuer within a reasonable period after such cancellation, termination or expiration. Upon release of any portion of the Collateral deposited by the Applicant in accordance with this Section 5(a), the Collateral Agent shall promptly execute and deliver to the Applicant, at the Applicant’s expense, such documents as the Applicant shall reasonably request to evidence the release of such Collateral from any Lien granted to the Collateral Agent. Notwithstanding anything to the contrary herein, the Applicant shall at all times be permitted to withdraw Eligible Treasury Assets from the Trust Collateral Account and deposit such Eligible Treasury Assets into the Constellation Collateral Accounts pursuant to a mandatory exercise of the issuance right under the Facility Agreement that is triggered by an Investment Company Act Event.

(b)The Applicant shall use commercially reasonable efforts to establish the Constellation Securities Account within 14 days after the date hereof.

(c)The Applicant will (i) comply in all material respects with all applicable U.S. and foreign laws, regulations (including foreign exchange control regulations, foreign asset control regulations and other trade-related regulations) and rules now or later applicable to any Letter of Credit or this Agreement and the transactions contemplated thereunder and hereunder, or the Applicant’s execution, delivery and performance under this Agreement, (ii) preserve and maintain in full force and effect its limited liability company existence and good standing under the laws of its jurisdiction of organization, and (iii) pay and discharge as the same shall become due and payable, all of its material Taxes, assessments and governmental levies, except as such are being contested in good faith by appropriate proceedings and for which adequate reserves are being maintained in accordance with U.S. generally accepted accounting principles or where failure to effect such payment is not adverse in any material respect to the Issuers.

(d)The Applicant will comply, in all material respects, with the PATRIOT Act. The Applicant will not, directly or, to the knowledge of the Applicant, indirectly, use any Letter of Credit: (i) to fund any activities or business of or with any Person that, at the time thereof, is the subject of Sanctions or in any country or territory that, at the time thereof, is the subject of comprehensive Sanctions, or (ii) in any other manner that would result in a violation of Sanctions by any Person (including any Person participating in the transactions contemplated hereby, whether as an issuer, underwriter, investor, or otherwise).

(e)The Applicant will furnish to the Administrative Agent for distribution to each Issuer:

(i)within forty-five (45) days after the end of each of the first three quarters of each fiscal year of the Applicant beginning with the fiscal quarter ending on March 31, 2022, its unaudited consolidated balance sheet and related statements of income, stockholders’ equity and cash flows showing the financial condition as of the close of such fiscal quarter of the Applicant and its consolidated Subsidiaries at such time and the results of its operations and the operations of such Subsidiaries during such fiscal quarter, certified by the chief financial officer or other responsible officer of the Applicant to the effect that such financial statements, while not examined by independent public accountants, reflect in the opinion of the Applicant all adjustments necessary to present fairly in all material respects the financial condition and results of operations of the Applicant and its consolidated Subsidiaries on a consolidated basis as of the end of and for such periods in accordance with GAAP consistently applied, subject to normal year-end audit adjustments and the absence of footnotes;

(ii)within ninety (90) days after the end of each fiscal year of the Applicant beginning with the fiscal year ending on December 31, 2022, the Applicant’s consolidated balance sheet and related statements of income, stockholders’ equity and cash flows showing the financial condition as of the close of such fiscal year of the Applicant and its consolidated Subsidiaries at such time and the results of its operations and the operations of such Subsidiaries during such year, all audited by PricewaterhouseCoopers LLP or other independent public accountants of recognized national standing and accompanied by an opinion of such accountants to the effect that such consolidated financial statements fairly present the financial condition and results of operations of the Applicant and its consolidated Subsidiaries on a consolidated basis in accordance with GAAP consistently applied;

(iii)promptly upon the Applicant becoming aware of the occurrence of each Event of Default, a statement of the chief financial officer or other responsible officer of the Applicant setting forth details of such Event of Default and the action which the Applicant has taken and proposes to take with respect thereto;

(iv)information and documentation reasonably requested in writing by any Issuer for purposes of compliance with applicable “know your customer” requirements under the PATRIOT Act or other applicable anti-money laundering rules and regulations;

(v)prompt written notice of any change in the information provided in any Beneficial Ownership Certification that would result in a change to the list of beneficial owners identified in parts (c) or (d) of such certification; and

(vi)such other information relating to the business, operations, assets, liabilities or condition, financial or otherwise, of the Applicant as any Issuer (acting through the Administrative Agent) may from time to time reasonably request promptly following such request.

    Documents required to be delivered pursuant to Section 5(e)(i) and (ii) (to the extent any such documents are included in materials otherwise filed with the SEC) may be delivered electronically and, if so delivered, shall be deemed to have been delivered on the date (i) on which such materials are publicly

available as posted on the Electronic Data Gathering, Analysis and Retrieval system (EDGAR); or (ii) on which such documents are posted on the Applicant’s behalf on an Internet or intranet website, if any, to which each Issuer and the Administrative Agent have access (whether a commercial, third-party website or whether made available by the Administrative Agent); provided that: (A) upon written request by the Administrative Agent (or any Issuer through the Administrative Agent) to the Applicant, the Applicant shall deliver paper copies of such documents to the Administrative Agent or such Issuer until a written request to cease delivering paper copies is given by the Administrative Agent or such Issuer and (B) the Applicant shall notify the Administrative Agent and each Issuer (by telecopier or electronic mail) of the posting of any such documents and provide to the Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents. The Administrative Agent shall have no obligation to request the delivery of or to maintain paper copies of the documents referred to above, and in any event shall have no responsibility to monitor compliance by the Applicant with any such request by an Issuer for delivery, and each Issuer shall be solely responsible for timely accessing posted documents or requesting delivery of paper copies of such document to it and maintaining its copies of such documents.

(f)The Applicant shall cause each established Collateral Account at all times to be under the sole dominion and control (within the meaning of Sections 8-106, 9-104 and/or 9-106 of the UCC, as applicable) of the Collateral Agent, and the Collateral Agent shall have the exclusive right of withdrawal over such account except as set forth in the Facility Agreement (as in effect on the date hereof).

6.Collateral Accounts Monitoring and Shortfalls; Withdrawal of Eligible Treasury Assets from Collateral Accounts.

(a)The Applicant agrees that the value of assets on deposit in the Collateral Accounts will be monitored by the Collateral Agent (or its sub-agent), and that the value of assets in the Collateral Accounts (the “Net Asset Value”) will be obtained according to the Collateral Agent’s (or its sub-agent’s) standard operating procedures on (i) each Collateral Valuation Date, and (ii) each other date as the Collateral Agent may be directed by the Majority Issuers in their discretion, in each case, in a commercially reasonable manner. For these purposes the value of any cash will be the face amount thereof and the value of any Eligible Treasury Assets will be obtained by reference to prices/quotes available on a reputable third party reporting or quotation service (such as Bloomberg, IDC or Reuters) or, if not so available, shall be their fair market value thereof as reasonably determined by the Collateral Agent or its sub-agent. The Collateral Agent shall have no liability for the value of any Eligible Treasury Assets obtained from a third party reporting service (or its sub-agent) and may, without further investigation, conclusively rely on such values. The Collateral Agent shall, no later than 12:00 p.m. on each Collateral Valuation Date, promptly provide notice to the Administrative Agent of the Net Asset Value.

(b)The Administrative Agent will, in the event that the aggregate Net Asset Value of the Collateral Accounts, as calculated on any Collateral Valuation Date, is less than the Minimum Collateral Base, on such day (a “Notice Date”), notify the Applicant and each Issuer of such shortfall by electronic mail transmission (a “Shortfall Notice”). If a Shortfall Notice is given prior to 10:00 a.m. on a Business Day, then such Business Day shall be the “Shortfall Date”; provided that if such notice is given after 10:00 a.m. on a Business Day or on a day that is not a Business Day, then the subsequent Business Day shall be the “Shortfall Date”. The Shortfall Notice shall include (i) the aggregate Net Asset Value in each Collateral Account as of the Notice Date, (ii) the aggregate L/C Outstandings as of the Notice Date and (iii) a calculation showing the amount of cash or Eligible Treasury Assets that the Applicant would be required to provide to the Collateral Agent for contribution to the Constellation Collateral Accounts, as set forth in Section 6(c), such that the Net Asset Value of the Collateral Accounts would be equal to the Minimum Collateral Base on any such Shortfall Date (such amount, the “Shortfall Amount”).

(c)On any Shortfall Date, the Applicant may, but shall not be required to, deposit an amount of cash in U.S. dollars and/or or Eligible Treasury Assets equal to the Shortfall Amount in the Constellation Collateral Accounts, with any such deposit to be made prior to 4:00 p.m. on the relevant Shortfall Date. If the Applicant has not made such deposit by such time, the Administrative Agent shall recalculate the Aggregate Availability and notify each Issuing Bank thereof. At any time thereafter, the

Applicant may in its sole discretion elect to deposit an additional amount of cash in U.S. dollars and/or Eligible Treasury Assets in the Constellation Collateral Accounts and shall provide the Administrative Agent notice of such deposit promptly after the deposit of such cash and/or Eligible Treasury Assets, and such amount shall be taken into account in the calculation of the Aggregate Net Asset Value of the Constellation Collateral Accounts on the following Collateral Valuation Date.

(d)In the event of any withdrawal by the Collateral Agent of Eligible Treasury Assets from any Collateral Account pursuant to Section 4(b), Section 16, or otherwise, the Collateral Agent and/or its sub-agent(s) shall (i) determine, in consultation with the Calculation Agent, the amount of Eligible Treasury Assets that would need to be monetized to satisfy the Obligations then due and payable, the selection of such Eligible Treasury Assets to be sold being at the sole discretion of the Collateral Agent (and its sub-agent) and in a manner consistent with the Pledge Agreement, (ii) sell such amount of Eligible Treasury Assets and (iii) apply the cash proceeds from such sale to satisfy the Obligations then due and payable in accordance with the terms hereof; provided that, in connection with the withdrawal by the Collateral Agent of Eligible Treasury Assets from the Collateral Accounts, the Collateral Agent shall use commercially reasonable efforts to select Eligible Treasury Assets to be monetized and sell such Eligible Treasury Assets on a pro rata basis across each principal and interest STRIP, selecting, to the extent practicable, (A) first from the Constellation Collateral Accounts (to the extent established), second from the Retained Eligible Treasury Assets Account and third from the Primary Eligible Treasury Assets, and (B) in each case, an equal percentage of each such principal and interest STRIP and, to the extent any such principal or interest STRIP to be selected would have a face amount less than $100, rounding such face amount to be selected up to the nearest $100. For the avoidance of doubt, in the event that a withdrawal by the Collateral Agent of Eligible Treasury Assets exceeds the amount necessary to satisfy the Obligations then due and payable, such excess proceeds from the monetization of the selected Eligible Treasury Assets will be deposited into the Constellation Collateral Account (or, if such account has not yet been established, into the Retained Eligible Treasury Assets Account, which proceeds shall be considered Retained Eligible Treasury Assets).

(e)Notwithstanding anything to the contrary herein, the Collateral Agent shall not withdraw, and each Issuer agrees that it shall not instruct the Collateral Agent to withdraw, a portion of any principal or interest STRIP to monetize in order to satisfy Obligations due to an Issuer if such withdrawal would exceed such Issuer’s Eligible Treasury Assets Cap with respect to any such principal or interest STRIP; provided that, if each Issuer’s Eligible Treasury Assets Cap has been reduced to zero and the Collateral Agent is permitted to withdraw additional Eligible Treasury Assets from the Collateral Accounts pursuant to Section 16, the Collateral Agent may withdraw, and any Issuer may instruct the Collateral Agent to withdraw, Eligible Treasury Assets from the Collateral Accounts to be monetized for the Issuers on a pro rata basis based on each Issuer’s respective Commitment. The covenant set forth in this Section 6(e) is solely for the benefit of the respective Issuers, and the Applicant shall have no rights under, and agrees that it shall not take any action to enforce or object to, this Section 6(e).

7.Representations and Warranties. The Applicant represents and warrants to the Agents and the Issuers as follows on the date hereof and as of the date of issuance (or continuance) of each Letter of Credit (or as of the date of any Amendment thereto):

The Applicant acknowledges that the Collateral Agent has control (within the meaning of Sections 8-106, 9-104 and/or 9-016, as applicable, of the UCC) over the Collateral Accounts now in existence and shall have control (within the meaning of Sections 8-106, 9-104 and/or 9-016, as applicable, of the UCC) over any Collateral Accounts established after the date hereof.

(d)The Collateral Agent, for the benefit of the Secured Parties, has a valid, first-priority perfected security interest in and lien on all of the Collateral granted by the Applicant, subject to no other Lien, other than Permitted Liens, securing all Obligations hereunder, and all filings and other actions necessary or desirable to perfect and protect such security interests granted by the Applicant have been duly taken. All funds, assets and property provided by the Applicant to the Collateral Agent pursuant to the Facility Documents are free and clear of any Lien, other than Permitted Liens, except for the liens and security interests created under the Pledge Agreement, and the Applicant was the legal and beneficial owner thereof at the time provided to the Collateral Agent.

(a)The Applicant agrees to pay to the applicable Issuer, promptly upon demand, all reasonable and documented out-of-pocket costs and expenses (including attorney’s fees of a single external counsel for all Issuers and Agents) (collectively, the “Issuer Costs”) that the Issuer may pay or incur, or has already paid or incurred on or prior to the date hereof, in connection with the issuance (or continuance) of any Letter of Credit (or any Amendment thereto) and the negotiation, preparation, execution, performance and delivery of this Agreement and the transactions contemplated hereby and thereby, as well as in connection with the enforcement of, and preservation of the Issuer’s rights hereunder and thereunder, including, without limitation:

(i)increased costs to the Issuer or any entity controlling the Issuer arising from the imposition or modification or effectiveness after the date hereof of any reserve, special deposit, insurance, or similar requirement by any Governmental Authority or from Taxes (other than (A) Non-Excluded Taxes that are imposed on any payments made hereunder or under any Facility Document, (B) Other Taxes, and (C) Taxes described in clauses (i) through (iv) in paragraph (a) of Section 9), including charges with respect to any Letters of Credit issued (or continued) by the Issuer;

(c)If any Issuer becomes entitled to claim any additional amount pursuant to Section 8(a), it shall promptly notify the Applicant of the event by reason of which it has become so entitled. A certificate as to any additional amount payable pursuant to Section 8(a), showing in reasonable detail the determination of the additional amount claimed, submitted by the applicable Issuer to the Applicant shall be conclusive in the absence of manifest error. The agreements in this Section 8 shall survive the termination of this Agreement and the payment of all other amounts payable hereunder.

(d)Failure or delay on the part of any Issuer to demand compensation pursuant to Section 8(a) shall not constitute a waiver of such Issuer’s right to demand such compensation; provided that the Applicant shall not be under any obligation to compensate any Issuer under pursuant to Section 8(a)(i) or (ii) with respect to any period prior to the date that is 270 days prior to such request.

(e)Payments of the Obligations shall be apportioned ratably among the Issuers (according to the aggregate unpaid Obligations owing to each Issuer) and payments of the fees shall, as applicable, be apportioned ratably among the Issuers (according to the Pro Rata Shares of each Issuer), except for fees payable solely to the Agents. All payments shall be remitted to the Administrative Agent and all such payments not constituting payment of specific fees shall be applied, ratably, subject to the provisions of this Agreement, first, to pay any fees, indemnities or expense reimbursements then due to the Agents from the Applicant; second, to pay any fees or expense reimbursements then due to the Issuers from the Applicant; third, to pay unpaid reimbursement obligations in respect of Letters of Credit; fourth, to the payment of any other Obligation; and fifth, to the extent of any excess, to the Applicant or to whosoever the Applicant may lawfully direct.

9.Taxes.

(a)All payments made by or on account of the Applicant under any Facility Document shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, including interest and penalties with respect thereto (“Taxes”), except as required by

applicable law. If any Taxes, excluding the following Taxes (such non-excluded Taxes, “Non-Excluded Taxes”):

(i)net income taxes, franchise taxes (imposed in lieu of net income taxes), and branch profits taxes, in each case, imposed on the Administrative Agent or any Issuer as a result of (A) a present or former connection between the Administrative Agent or Issuer and the jurisdiction of the Governmental Authority imposing such Tax or political subdivision or taxing authority thereof or therein (other than any such connection arising from the Administrative Agent or any Issuer having executed, delivered or performed its obligations or received a payment under, received or perfected a security interest under, engaged in any other transaction pursuant to, or enforced, this Agreement, any Letter of Credit, or any Facility Document) or (B) as a result of the Administrative Agent or Issuer being organized under the laws of, or having its principal office or, in the case of any Issuer, its applicable lending office located in, the jurisdiction imposing such Tax (or any political subdivision thereof);

(ii)in the case of an Issuer, U.S. federal withholding Taxes imposed on a Letter of Credit or any Facility Document pursuant to a law in effect on the date on which (A) such Issuer acquires such interest in the Letter of Credit or Facility Document (other than pursuant to an assignment request or requirement by the Applicant under Section 9(c)) or (B) such Issuer changes its lending office (other than pursuant to a request by the Applicant under Section 9(c));

(iii)with respect to amounts to be received by an Issuer, Taxes attributable to such Issuer’s failure to comply with Section 9(b), and with respect to amounts to be received by the Administrative Agent, Taxes attributable to Administrative Agent’s failure to comply with Section 9(b); and

(iv)any U.S. federal withholding tax imposed under Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof, any agreements entered into pursuant to Section 1471(b)(1) of the Code, and any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement, treaty or convention among Governmental Authorities and implementing such Sections of the Code (“FATCA”),

are required by applicable law to be deducted or withheld from any amounts payable to or for the account of the Administrative Agent or any Issuer hereunder or under any Facility Document, the amounts so payable shall be increased to the extent necessary in order that the Administrative Agent or Issuer (after deduction or withholding of all Non-Excluded Taxes) receives an amount equal to the sum it would have received had no such deduction or withholding been made. Whenever any Taxes are payable by the Applicant pursuant to this Section 9, as promptly as possible the Applicant shall send to the Administrative Agent a certified copy of an original official receipt received by the Applicant showing payment thereof (or if such document is not reasonably available to the Applicant, other documentary evidence of payment). The Applicant shall indemnify the Administrative Agent and each Issuer for (x) any Non-Excluded Taxes imposed on or with respect to any payment made by or on account of the Applicant under this Agreement or any Facilities Document and (y) any Other Taxes, in each case, payable or paid by the Issuer or Administrative Agent, whether or not such Non-Excluded Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Applicant by an Issuer (with a copy to the Administrative Agent) shall be conclusive absent manifest error. The agreements in this Section 9 shall survive the termination of this Agreement and the payment of all other amounts payable hereunder.

(b)Each Issuer shall deliver to the Applicant and the Administrative Agent, at the time or times reasonably requested by the Applicant or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Applicant or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. The Administrative Agent shall deliver to the Applicant, at the time or times reasonably requested by the

Applicant, such properly completed and executed documentation reasonably requested by the Applicant as will permit any payments to be made to the Administrative Agent without withholding. In addition, the Administrative Agent and any Issuer, if reasonably requested by the Applicant or the Administrative Agent (as applicable), shall deliver such other documentation prescribed by applicable law or reasonably requested by the Applicant or the Administrative Agent as will enable the Applicant or the Administrative Agent to determine whether or not such Issuer is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in this Section 9(b), the completion, execution and submission of such documentation (other than (A) an IRS Form W-9, (B) an applicable Form W-8, or (C) any documentation prescribed by FATCA (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Applicant or the Administrative Agent as may be necessary for the Applicant and the Administrative Agent to comply with their obligations under FATCA and to determine that such Issuer has complied with such Issuer’s obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment (provided that, solely for purposes of this clause (C), “FATCA” shall include any amendments made to FATCA after the date of this Agreement), in each case to the extent the Issuer is legally entitled to complete, execute and submit such documentation) shall not be required if in an Issuer’s reasonable judgment such completion, execution or submission would subject such Issuer to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Issuer.

(c)If any Issuer requests compensation under Section 8(a)(i) or (ii), or requires the Applicant to pay any Non-Excluded Taxes or Other Taxes or additional amounts to any Applicant or any Governmental Authority for the account of any Issuer pursuant to Section 9, then such Issuer shall (at the request of the Applicant) use reasonable efforts to designate a different lending office for funding or booking its Letters of Credit hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Issuer, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 8(a)(i) or (ii) or Section 9, as the case may be, in the future, and (ii) would not subject such Issuer to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Issuer. If any such Issuer has declined or is unable to designate a different lending office in accordance with this Section 9(c), then the Applicant may, at its sole expense and effort, upon notice to such Issuer and the Administrative Agent, require such Issuer to assign and delegate, without recourse, all of its interests, rights and obligations under this Agreement and the related Facility Documents to a permitted assignee that shall assume such obligations.

(d)If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to Section 9 (including by the payment of additional amounts pursuant to this Section 9), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 9 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 9(d) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 9(d), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 9(d) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 9(d) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

10.Indemnity. The Applicant hereby agrees to indemnify and hold harmless each Agent, each Issuer and each Related Party of each Agent and each Issuer (“Indemnified Parties”), promptly upon demand and to the fullest extent legally permissible, and hold each of them harmless from and in respect of any and all losses, damages, liabilities, expenses (including, without limitation, expenses of investigation and defense and reasonable and documented out-of-pocket fees, charges and disbursements

of counsel), claims, liens or other obligations of any nature whatsoever (including, without limitation, the costs of enforcing this provision) that may arise out of any claim, litigation, investigation or proceeding in any connection whatsoever with this Agreement or a Letter of Credit, whether or not any Indemnified Parties are party to any such action and whether or not brought by third parties or the Applicant or its affiliates, other than losses, damages, liabilities, expenses, claims, liens or other obligations that (a)  arise out of such Indemnified Party’s gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction in a non-appealable final judgment or (b) arise out of any claim, litigation, investigation or proceeding brought by such Indemnified Party against another Indemnified Party (other than any claim, litigation, investigation or proceeding that is brought by or against an Agent, acting in its capacity as such) that does not involve any act or omission of the Applicant. The agreements in this Section 10 shall survive the termination of this Agreement and the payment of all other amounts payable hereunder.

The effectiveness of this Agreement is subject to the satisfaction or waiver of the following conditions precedent (such initial date of satisfaction of such obligations and receipt of such items being the “Execution Date”); provided that, the obligations of the Issuers to issue Letters of Credit hereunder shall be subject to the satisfaction or waiver of the conditions precedent set forth in Section 12 below:

Following an Event of Default, the Collateral Agent shall have no duty of care as a secured party hereunder to the Applicant as to any Collateral or with respect to the taking of any necessary steps to preserve rights against other parties or any other obligations pertaining to the Collateral, other than as may be expressly required by the UCC. The Applicant waives all rights whatsoever against each Agent for any loss, expense, liability or damage suffered by the Applicant as a result of actions taken by any such Agent as secured party pursuant to this Agreement or any other Facility Document, except to the extent caused by the gross negligence or willful misconduct of such Agent, as determined by a court of competent jurisdiction in a non-appealable final judgment.

(f)The Applicant hereby expressly waives, to the fullest extent permitted by law, every statute of limitation, right of redemption, any moratorium or redemption period, any limitation on a deficiency judgment, and any right which it may have to direct the order in which any of the Collateral shall be disposed of in the event of any disposition pursuant hereto.

(g)Each of the Issuers agrees that it shall not, unless specifically requested to do so by the Administrative Agent or the Collateral Agent, take or cause to be taken any action to enforce its rights under this Agreement or any Facility Document or against the Applicant.

17.Amendments; Waivers. Any provision of this Agreement may be amended, supplemented or waived if, but only if, such amendment, supplement or waiver is in writing and signed by each of the

Applicant, the Administrative Agent and the Majority Issuers, and shall be effective only in the specific instance and for the specific purpose for which it is given; provided that no such amendment, supplement or waiver shall increase or extend the Commitment of any Issuer without the written consent of such Issuer (it being understood that such increase may be effected solely with the consent of the Applicant and such Issuer); provided, further, that no such amendment, supplement or waiver shall, unless in writing and signed by all of the affected Issuers, the Administrative Agent and the Applicant, do any of the following:

Notwithstanding the foregoing, (i) the consent of the Issuers shall not be required for any amendment (A) to cure any mutually identified ambiguity or correct any mutually identified mistake or (B) to correct or supplement any provision of this Agreement that may be defective or inconsistent with any other provision of this Agreement, the Facility Agreement or the Trust Declaration and (ii) after the execution and delivery of the Issuer Joinder Agreement, Schedule I attached hereto may be amended from time to time with respect to any Issuer solely with the written consent of the Applicant and such Issuer (and notice thereof to the Administrative Agent), and no other consent will be required hereunder to establish, increase or decrease the Commitments of such Issuer; it being understood that the Applicant and the Administrative Agent shall be permitted to make technical amendments to this Agreement as may be necessary or appropriate in the reasonable opinion of the Applicant and the Administrative Agent to reflect any such newly established or increased Commitments of an Issuer; provided that, if any amendment to Schedule I attached hereto shall cause the Facility Amount to exceedthe amount set forth in the proviso to the definition of Facility Amount, such amendment shall be subject to the consent requirement under clause (g) above.

In the case of any waiver, the Applicant and the Issuers shall be restored to their former positions and rights hereunder and any Event of Default waived shall be deemed to be cured and not continuing, but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereon.

vote in respect of waivers, amendments or modifications to any Facility Document and the Commitment and the Obligations of such Defaulting Issuer hereunder shall not be taken into account in determining whether the Majority Issuers or all of the Issuers, as required by this Section 17 or otherwise, have approved any such waiver, amendment or modification (and the definition of “Majority Issuers” will automatically be deemed modified accordingly for the duration of such period); provided that any such waiver, amendment or modification that would increase or extend the Commitment of such Defaulting Issuer, extend the date fixed for the payment of interest or other amounts owing to such Defaulting Issuer hereunder, reduce the principal amount of any Obligation owing to such Defaulting Issuer, reduce the rate of interest on any Obligation owing to such Defaulting Issuer or of any fee payable to such Defaulting Issuer hereunder, or alter the terms of this proviso, shall require the prior written consent of such Defaulting Issuer.

18.The Agents.

(a)Appointment and Authorization. Applicant requests the Administrative Agent and Collateral Agent to enter into this Agreement and the Pledge Agreement prior to the Issuer Joinder Agreement and authorizes the Administrative Agent to enter into the Issuer Joinder Agreement. Each Issuer hereby designates and appoints each of the Administrative Agent and the Collateral Agent (the Administrative Agent and the Collateral Agent are referred to collectively as the “Agents”) as its agent under this Agreement and the other Facility Documents, and each Issuer hereby irrevocably authorizes the Agents to take such actions on its behalf under the provisions of this Agreement and each other Facility Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Facility Document, together with such powers as are reasonably incidental thereto. Each Agent is hereby authorized to execute, deliver and perform each of the Facility Documents to which the Administrative Agent or the Collateral Agent, as the case may be, is a party. Each Agent agrees to act as such on the express conditions contained in this Section 18. The provisions of this Section 18 are solely for the benefit of the Agents and the Issuers and the Applicant shall not have any rights as a third party beneficiary of any of the provisions contained herein. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Facility Document, no Agent shall have any duties or responsibilities, except those expressly set forth herein, nor shall any Agent have or be deemed to have any fiduciary relationship with any Issuer, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Facility Document or otherwise exist against any Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Agreement with reference to any Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Notwithstanding the foregoing, prior to the execution and delivery of the Issuer Joinder Agreement, each Agent shall be entitled to rely on instructions delivered to such Agent by the Applicant in connection with the taking of any actions under the provisions of this Agreement and each other Facility Document; provided that immediately upon the execution and delivery of the Issuer Joinder Agreement, each Agent shall thereafter act hereunder as directed by the Issuers as set forth herein.

(b)Delegation of Duties. Each Agent may perform any and all of its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it and shall not be liable for the negligence or misconduct of a sub-agent appointed with due care. Each Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section 18 shall apply to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Agent. The parties hereto acknowledge that as of the Execution Date, the Collateral Agent has appointed Credit Suisse Securities (USA) LLC, in its capacity as Calculation Agent (as defined in the Calculation Agency Agreement), as sub-agent for purposes of (i) determining the fair market value of Eligible Treasury Assets under Section 6(a), if necessary, (ii) the duties under Section 6(d)(i) and Section 6(d)(ii) of this Agreement, including the determination of the pro rata amount of each interest and principal STRIP as set forth in the provision of such Sections and (iii) any determination of a Percentage

Pro Rata Basis under the Pledge Agreement, together with such powers as are reasonably incidental thereto.

(c)Liability of Agents. None of the Agent-Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Facility Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Issuers for any recital, statement, representation or warranty made by the Applicant or affiliate of the Applicant, or any officer thereof, contained in this Agreement or in any other Facility Document, or in any certificate, report, statement or other document referred to or provided for in, or received by any Agent under or in connection with, this Agreement or any other Facility Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Facility Document, or for any failure of the Applicant or any other party to any Facility Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Issuer to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Facility Document, or to inspect the properties, books or records of the Applicant. The Agents shall not be responsible for and make no representation as to the existence, genuineness, value or protection of any Collateral, for the legality, effectiveness or sufficiency of the Pledge Agreement or for the creation, perfection, priority, sufficiency or protection of any liens securing the Obligations. Nothing herein shall require the Agents to file financing statements or continuation statements, or be responsible for maintaining the security interests purported to be created as described herein (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder or under any other Facility Document) and such responsibility shall be solely that of the Applicant. No Agent shall incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of such Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war, pandemic, epidemic, civil unrest, local or national disturbance or disaster, any act of terrorism, or the unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility). The Agents shall not be required to expend or risk any of its own funds or otherwise incur any liability, financial or otherwise, in the performance of any of its duties hereunder or under any other Facility Document.

(d)Reliance by Agent. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex, electronic mail or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Applicant), independent accountants and other experts selected by such Agent. Each Agent shall be fully justified in failing or refusing to take any action or exercising any discretion or right under this Agreement or any other Facility Document unless it shall first receive such advice or concurrence of the Majority Issuers as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Issuers against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action; provided, that the Agents shall not be required to take any action that would violate any Facility Document or applicable law. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Facility Document in accordance with a request or consent of the Majority Issuers (or all Issuers if so required by Section 17) and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Issuers. The Agents may consult with legal counsel of its own choosing, at the expense of the Applicant, as to any matter relating to the Facility Documents, and the Agents shall not incur any liability in acting in good faith in accordance with any advice from such counsel.

(e)Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Event of Default, unless such Agent shall have received written notice from an Issuer or the Applicant in accordance with the provisions of Section 19, referring to this Agreement, describing such Event of Default and stating that such notice is a “notice of default.” The applicable Agent will notify the Issuers of its receipt of any such notice. The Agents shall take such action with respect to such Event of Default as may be requested by the Majority Issuers in accordance with Section 16; provided,

however, that unless and until the Agents have received any such request, the Agents may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Event of Default as it shall deem advisable.

(f)Credit Decision. Each Issuer acknowledges that none of the Agent-Related Persons has made any representation or warranty to it, and that no act by any Agent hereinafter taken, including any review of the affairs of the Applicant and its Affiliates, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Issuer. Each Issuer represents to each Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Applicant, and all applicable bank regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Applicant. Each Issuer also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Facility Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of Applicant. Except for notices, reports and other documents expressly herein required to be furnished to the Issuers by an Agent, no Agent shall have any duty or responsibility to provide any Issuer with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of the Applicant which may come into the possession of any of the Agent-Related Persons.

(g)Indemnification. Whether or not the transactions contemplated hereby are consummated, the Issuers shall indemnify upon demand the Agent-Related Persons (to the extent not reimbursed by or on behalf of the Applicant and without limiting the obligation of the Applicant to do so), in accordance with their Pro Rata Shares, from and against any and all indemnified liability pursuant to Section 10; provided, however, that no Issuer shall be liable for the payment to the Agent-Related Persons of any portion of such Indemnified Liabilities resulting solely from such Person’s gross negligence or willful misconduct. Without limitation of the foregoing, each Issuer shall reimburse each Agent upon demand for its Pro Rata Share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by such Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Facility Document, or any document contemplated by or referred to herein, to the extent that such Agent is not reimbursed for such expenses by or on behalf of the Applicant. The undertaking in this Section shall survive the payment of all Obligations hereunder and the resignation or replacement of the applicable Agent.

(h)Agent in Individual Capacity. Deutsche Bank Trust Company Americas and its affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Applicant and its Subsidiaries and affiliates as though Deutsche Bank Trust Company Americas were not an Agent hereunder and without notice to or consent of the Issuers. Deutsche Bank Trust Company Americas or its affiliates may receive information regarding the Applicant and its affiliates (including information that may be subject to confidentiality obligations in favor of the Applicant) and acknowledge that the Agents and Deutsche Bank Trust Company Americas shall be under no obligation to provide such information to them.

(i)Successor Agent. Any Agent may resign as Administrative Agent and/or Collateral Agent, as applicable, upon at least thirty (30) days’ prior written notice to the Issuers and the Applicant, such resignation to be effective upon the acceptance of a successor agent to its appointment as Administrative Agent or Collateral Agent, as applicable. Subject to the foregoing, if any Agent resigns under this Agreement, the Majority Issuers shall appoint from among the Issuers a successor agent for the Issuers. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Issuers and the Applicant, a successor agent from among the Issuers, or, at the expense of the Applicant, apply to a court of competent jurisdiction for the appointment

of a successor. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the term “Administrative Agent” and/or “Collateral Agent”, as applicable, shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 18 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

21.No Waiver; Remedies Cumulative. No failure to exercise, and no delay in exercising any right, power or remedy under this Agreement or any other document executed and delivered in connection herewith shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The rights, remedies, powers and privileges provided under this Agreement are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law or in equity.

The entries in the Register shall be conclusive absent manifest error, and the Applicant, the Administrative Agent and the Issuers shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as an Issuer hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Applicant and any Issuer, at any reasonable time and from time to time upon reasonable prior notice.

Notwithstanding the foregoing, each Issuer may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure its obligations, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this paragraph shall not apply to any such pledge or assignment of a security interest.

23.Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

24.Right of Set-off. If an Event of Default shall have occurred and be continuing, each Issuer is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set-off and apply any and all deposits (general or special, time or demand, provisional or final, including, without limitation, any amount held by the Issuer pursuant to this Agreement or otherwise) at any time held and other indebtedness at any time owing by the Issuer to or for the credit or the account of the Applicant against any and all of the Obligations (now or hereafter existing) that are due and payable hereunder or under any related document. The rights of the Issuers under this Section 24 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that any Issuer may have.

30.PATRIOT Act and Beneficial Ownership Regulation Notice. Each Issuer hereby notifies the Applicant that pursuant to the requirements of the PATRIOT Act and the Beneficial Ownership Regulation, it is required to obtain, verify and record information that identifies the Applicant (and related information), which information includes the name and address of the Applicant and other information that will allow it to identify the Applicant in accordance with the PATRIOT Act and the Beneficial Ownership Regulation.
