for an amendment to an existing Letter of Credit (an “Amendment”), each Issuer severally agrees to issue (or
continue) such Letter of Credit or Letters of Credit (in each case, in a form reasonably satisfactory to such Issuer), or agree
to such Amendment, as the case may be. If requested by the applicable Issuer, the Applicant also shall submit a letter of credit
application on such Issuer’s standard form in connection with any request for a Letter of Credit. Each Issuer’s obligation
to effect such issuance, continuance or Amendment shall be subject to the following conditions: (i) prior satisfaction by
the Applicant of its obligations set forth in Section 5(a), (ii) 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 (iii) all representations and warranties contained in this Agreement are 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 (iii). 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).


 


(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 which 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.


 






    10


     


    

 


(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 rules of the International Standby Practices 1998 (ISP98) (or such
later version thereof as may be in effect at the time of issuance) shall apply to each standby Letter of Credit.


 


(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 a copy of such Letter of Credit (and any amendments, renewals, increases or extensions
thereof) to the Administrative Agent. Each Issuer shall provide to the Administrative Agent, within 10 Business Days of the end
of each calendar month, 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.


 






    11


     


    

 


(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 NRG Collateral Account an amount
of cash and/or Eligible UST 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 UST Assets on deposit in or credited to the NRG Collateral Account on any such date, the Collateral Agent
shall withdraw from the Trust Collateral Account (in accordance with Section 6(d)) an amount of Eligible UST 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
(x) authorizes and directs the Collateral Agent to charge the NRG Collateral Account (i) 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 (ii) from time to time for any other Obligations not paid
within five (5) Business Days after the due date thereof and (y) confirms that it has irrevocably directed and caused
the Trust to authorize and direct the Collateral Agent to charge the Trust Collateral Account (i) 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 (ii) 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. 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 UST Assets deposited in or credited
to the NRG Collateral Account and (ii) the aggregate Net Asset Value of Eligible UST 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 NRG Collateral Account, 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, 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.


 






    12


     


    

 


(b)          The
Applicant hereby agrees that it 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, preserve and maintain in full force and effect its
corporate 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.


 


(c)          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: (A) 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 (B) 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).


 


(d)          The
Applicant hereby agrees that it 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, 2021, 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,
2020, 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 KPMG 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;


 






    13


     


    

 


(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.


 


(f) 
The Applicant shall cause each Collateral Account at all times to be under the sole dominion and control (within the meaning of
Section 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
Account Monitoring and Shortfalls; Withdrawal of Eligible UST 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 UST 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 UST 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 of 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 UST Assets that the Applicant would be required to provide
to the Collateral Agent for contribution to the NRG Collateral Account, 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”).


 






    14


     


    

 


(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
UST Assets equal to the Shortfall Amount in the NRG Collateral Account, 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 UST Assets in the NRG Collateral Account and shall
provide the Administrative Agent notice of such deposit promptly after the desposit of such cash and/or Eligible UST Assets, and
such amount shall be taken into account in the calculation of the Aggregate Net Asset Value of the NRG Collateral Account on the
following Collateral Valuation Date.


 


(d)          In
the event of any withdrawal by the Collateral Agent of Eligible UST Assets from any Collateral Account pursuant to Section 4(b),
Section 15, or otherwise, the Collateral Agent and/or its sub-agent(s) shall (i) determine the amount of Eligible
UST Assets that would need to be monetized to satisfy the Obligations then due and payable, the selection of such Eligible UST
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 UST Assets and (iii) apply the cash proceeds from such sale to satisfy
the Obligations then due and payable in accordance with the terms hereof.


 


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):


 


(a)          (i) It
is a corporation duly organized, validly existing and in good standing under the laws of the state of Delaware and (ii) has
(x) all the requisite powers and (y) all material government licenses, authorizations, consents and approvals required
to carry on its business as now conducted, except, in the case of this clause (ii), to the extent the failure to do so could not
reasonably be expected to result in a material adverse effect on the Applicant’s business, operations, property, assets,
liabilities or financial condition.


 


(b)          The
(i) execution, delivery and performance by it of this Agreement, (ii) the granting of the Liens granted by it (including
the first priority nature thereof, subject to Permitted Liens) pursuant to the Pledge Agreement, (iii) the perfection or
maintenance of the Liens created pursuant to the Pledge Agreement, and (iv) the granting of authority to the Agents and the
Issuers with respect to the exercise of their respective rights hereunder or under any other Facility Document or remedies in
respect of the Collateral Accounts, (v) are within its corporate powers, (w) have been duly authorized by all necessary
corporate action, (x) require no action by or in respect of, or filing with, any governmental body, agency or official, except
for any immaterial actions, consents, approvals, registrations or filings or such as have been made or obtained and are in full
force and effect, (y) do not contravene, or constitute a default under, any provision of applicable material law or regulation
or of constituent documents of the Applicant, as the case may be, or of any material agreement, judgment, injunction, order, decree
or other material instrument binding upon the Applicant, as the case may be, or any of its subsidiaries, or (z) result in
the creation or imposition of any Lien on any asset of the Applicant or any of its subsidiaries, except the Liens created pursuant
to the Pledge Agreement.


 


(c)          This
Agreement and each other Facility Document have each been duly executed and delivered by the Applicant. Each of this Agreement
and each other Facility Document constitutes a legal, valid and binding agreement of the Applicant, enforceable against it in
accordance with its terms, except to the extent such enforceability may be limited by the effect of applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer or other similar laws affecting the enforcement of creditors’ rights generally
or by general principles of equity. The Applicant acknowledges that the Collateral Agent has control (within the meaning of Section 9-104
and/or 9-016, as applicable, of the UCC) over the Collateral Accounts.


 






    15


     


    

 


(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.


 


(e)          Both
immediately before and immediately after the issuance (or continuance) of each Letter of Credit (or Amendment thereto), no Event
of Default shall have occurred and be continuing.


 


(f)           The
Applicant is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended. Neither
the issuance (or continuance) of the Letters of Credit (or any Amendment thereto) nor the transactions contemplated hereunder
will violate any provision of such Act or any rule, regulation or order of the Securities and Exchange Commission thereunder.


 


(g)          There
is no action, suit, investigation, litigation or proceeding against the Applicant pending or, to the knowledge of the Applicant,
threatened, before any court, tribunal, arbitrator or any other Governmental Authority or national securities exchange, that purports
to affect the legality, validity or enforceability of this Agreement or as to which there is a reasonable possibility of an adverse
determination and that, if adversely determined, would reasonably be expected to result in a material adverse effect on the Applicant’s
business, operations, property, assets, liabilities or financial condition.


 


(h)          The
Applicant is Solvent.


 


(i)           The
information included in the Beneficial Ownership Certification is true and correct in all material respects.


 


(j)           None
of the Applicant, any of its Subsidiaries or, to the knowledge of the Applicant, any director, officer or employee of the Applicant
or any of its subsidiaries, is a Sanctioned Person. No part of the proceeds of the Letters of Credit or payment or disbursement
made pursuant thereto will be used directly or, to the knowledge of the Applicant, indirectly, (i) in violation of Anti-Corruption
Laws or violation of Section 5(c) hereof.


 


(k)          The
Facility Documents and the transactions contemplated thereby do not violate Regulations T, U or X of the Board of Governors of
the Federal Reserve.


 


All representations
and warranties made or deemed made in this Agreement shall survive the execution and delivery of this Agreement and the issuance
(or continuance) of any Letter of Credit (or any Amendment thereto).


 


8.            Issuance
Fee / Issuer Costs; Application of Payments.


 


(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:


 






    16


     


    

 


(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 (x) Non-Excluded Taxes that are imposed on any payments made hereunder or under any Facility Document, (y) Other
Taxes, and (z) 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;


 


(ii)            increased
costs to the Issuer or any entity controlling the Issuer for issuing, continuing or maintaining any Letter of Credit or a reduction
in the yield or amount received or receivable by the Issuer or any entity controlling the Issuer for issuing, continuing or maintaining
any Letter of Credit, arising from any change in any applicable law, rule, regulation, guideline, request or directive, or any
change in the interpretation of any of the foregoing (whether or not having the force of law) imposed or becoming effective after
the date hereof by any Governmental Authority or agency imposing on the Issuer or such entity or any other condition affecting
this Agreement or any Letter of Credit (or any Amendment thereto) or its issuance or continuance (including as to liquidity or
capital adequacy), in each case imposed or becoming effective after the date hereof by any Governmental Authority or agency that
has jurisdiction over the Issuer or any such entity controlling the Issuer (notwithstanding anything herein to the contrary, (x) the
Dodd-Frank Wall Street Reform and Consumer Protection Act, and (y) all requests, rules, guidelines, requirements and directives
promulgated thereunder, and all requests, rules, guidelines, requirements and directives promulgated by the Bank of International
Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign
regulatory authorities, in each case pursuant to Basel III, are deemed to have been introduced or adopted after the date hereof,
regardless of the date enacted, adopted, issued or implemented); and


 


(iii)           all
documented out-of-pocket sums expended by the Agents and the Issuers, including, without limitation, reasonable and documented
attorney’s fees, disbursements and court costs, in connection with the exercise of any right or remedy provided for herein,
the preservation of the Collateral and the Issuer’s interest therein and the defense or prosecution of any actions, suits
or proceedings arising out of or relating to the Collateral.


 


(b)          The
Applicant shall pay the following fees:


 


(i)             to
the Administrative Agent, for the account of each Issuer, a fee (the “L/C Fee”) as follows:


 


(1)            for
the period from the Effective Date through and including March 31, 2021, in an amount equal to 0.55% of the Stated Amount
of all outstanding Letters of Credit issued by such Issuer pursuant to this Agreement; and


 


(2)            for
the period from and after April 1, 2021 until the Termination Date, in an amount equal to 0.55% of such Issuer’s aggregate
Commitment hereunder,


 


in each case, payable quarterly
in arrears on each L/C Fee Payment Date; and


 


(ii)            to
the Administrative agent, for its own account, an annual administration fee in the amount agreed in writing pursuant to that certain
Fee Proposal dated as of November 16, 2020 by the Administrative Agent and accepted by the Applicant, or as otherwise agreed
in writing from time to time between the Applicant and the Administrative Agent.


 






    17


     


    

 


Once paid, none of
the fees shall be refundable under any circumstances. For the avoidance of doubt, the fees shall be in addition to any reimbursements
of the Issuer’s out-of-pocket expenses pursuant to Section 8. Notwithstanding anything contained herein to the
contrary, during such period as an Issuer is a Defaulting Issuer, such Defaulting Issuer will not be entitled to any L/C Fee accruing
during such period.


 


(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 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:


 


(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 (x) 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 (y) 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 (x) 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 (y) such Issuer
changes its lending office (other than pursuant to a request by the Applicant under Section 9(c)),


 






    18


     


    

 


(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”).


 


(such non-excluded Taxes, “Non-Excluded
Taxes”) 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 (i) 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 (ii) 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 (i) an IRS Form W-9, (ii) an applicable
Form W-8, or (iii) 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 (iii), “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.


 






    19


     


    

 


(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
(i) may 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 (ii) 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.

against any Beneficiary or any transferee of any Letter of Credit (or any Persons for whom such Beneficiary or any such transferee
may be acting), the applicable Issuer, or any other Person, whether in connection with this Agreement or otherwise;

failure by the Issuer to make payment under any Letter of Credit as a result of any requirement of law, control or restriction
rightfully or wrongfully exercised or imposed by any Governmental Authority;

other act or omission to act or delay of any kind of the Issuer or any other Person or any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the provisions of this Section 12, constitute a

be construed to excuse any Issuer from liability to the Applicant to the extent of any direct damages suffered by the Applicant
that are caused by such Issuer’s gross negligence or willful misconduct, as determined by a court of competent jurisdiction
by final and nonappealable judgment, in determining whether drafts and other documents presented under a Letter of Credit comply
with the terms thereof. It is understood that each Issuer may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under
any Letter of Credit (A) the Issuer’s exclusive reliance on the documents presented to it under such Letter of Credit
as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit,

pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order,
and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or
invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever, and (B) any noncompliance in
any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed

for any action taken or omitted by such Issuer under or in connection with this Agreement, any Letter of Credit (or any Amendment
thereto) or a related draft or documents, if done in the absence of gross negligence and willful misconduct and in accordance
with any mandatory standard of care applicable under the Uniform Commercial Code of the State of New York, as in effect from time
to time (the “UCC”) and the International Standby Practices 1998 (ISP98), as in effect from time to time (provided
that in the event of a conflict, the applicable provisions of the UCC shall govern to the extent of such conflict).

ratable portion of all such distributions by the Administrative Agent, such Issuer shall promptly turn the same over to the Administrative
Agent, in kind, and with such endorsements as may be required to negotiate the same to the Administrative Agent, or in same day
funds, as applicable, for the account of all of the Issuers and for application to the Obligations in accordance with the applicable

is to accelerate the maturity of such Indebtedness or otherwise to cause such Indebtedness to mature, or any such Indebtedness
shall be declared to be due and payable or required to be prepaid or redeemed, purchased or defeased, or an offer to prepay, redeem,
purchase or defease such Indebtedness shall be required to be made, in each case prior to the stated maturity thereof and other
than by a regularly scheduled required prepayment or redemption other than (i) pursuant to customary asset sale provisions
or (ii) delivery of a notice of voluntary prepayment or redemption; or


 


(ix)          any
provision of this Agreement or any other Facility Document shall at any time for any reason cease to be valid and binding on the
Applicant, or shall be declared to be null and void, or the validity or enforceability thereof shall be contested by the Applicant,
or a final decision by a court, any governmental agency or other authority having jurisdiction over the Applicant shall establish
the invalidity or unenforceability thereof, or the Applicant shall deny that it has any or further liability or obligation under
this Agreement.


 


(b)         Upon
the occurrence and during the continuance of an Event of Default, and upon every such occurrence and during such continuance, in
addition to all rights and remedies set forth in this Agreement and/or otherwise available under applicable law, (x) the unused
Commitments of the Issuers hereunder shall automatically terminate and (y) the Agents may, and at the direction of the Issuers
then holding a majority of the L/C Outstandings, shall:


 


(i)           declare
all amounts (whether direct or contingent) payable hereunder to be, and such amounts shall thereupon become, immediately due and
payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Applicant;


 






    26


     


    

 


(ii)           apply,
sell or otherwise liquidate and realize upon any and all funds, assets or property in the Collateral Accounts in satisfaction of
the Obligations;


 


(iii)          do
any acts which it deems proper to protect the Collateral as security hereunder, and collect and sue upon the Collateral and receive
any payments due thereon or any damages thereunder, and apply all sums received in connection with the Collateral to the payment
of the Obligations in such order as the Administrative Agent shall determine;


 


(iv)          require
the Applicant to deliver to the Collateral Agent all documents in the possession of the Applicant relating to the Collateral, and
the Applicant shall promptly take such actions and furnish to the Collateral Agent such documents as the Issuer deems necessary
or appropriate, in its sole discretion, to enforce its rights with respect to the Collateral;


 


(v)          direct
the Securities Intermediary to make all payments and deliveries under the Collateral directly to the Collateral Agent or its designee,
and the Applicant shall, and shall direct the Trust to, upon request by the Collateral Agent and as applicable, execute and consent
to all notices and directions given by the Collateral Agent to the Securities Intermediary, including transferring all Collateral
to accounts maintained solely in the name of the Collateral Agent. For avoidance of doubt, the Collateral Agent may exercise remedies
against the NRG Collateral Account (including any Collateral on deposit therein or credited thereto) and the Trust Collateral Account
(including any Collateral on deposit therein or credited thereto) in such order as the Collateral Agent shall decide in its sole
discretion and shall have no duty to marshall any Collateral;


 


(vi)         exercise,
or cause the exercise of, the Applicant’s rights under or in respect of any Collateral; and/or


 


(vii)        exercise
or cause the exercise of any other rights or remedies provided herein, in any document or instrument delivered pursuant
hereto, under any other agreement or under applicable law (including, without limitation, any rights or remedies under the UCC).


 


(c)          each
Agent may enforce its rights and remedies hereunder without prior judicial process or hearing, and the Applicant hereby expressly
waives, to the fullest extent permitted by law, any right the Applicant might otherwise have to require any Agent to enforce its
rights by judicial process. The Applicant also waives, to the fullest extent permitted by law, any defense the Applicant might
otherwise have to the Obligations secured hereby arising from use of nonjudicial process, enforcement and sale of all or any portion
of the Collateral or from any other election of remedies, in each case, to the extent permitted under the UCC.


 


(d)         If
the Collateral is insufficient to cover the payment in full of all Obligations, the Applicant shall remain liable for any deficiency.


 


(e)          The
powers conferred on each Agent hereunder are solely for its benefit and for the benefit of the Issuers and do not impose any duty
on any Agent to exercise any such powers. 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.


 






    27


     


    

 


(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.


 


16.          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:


 


(i)            postpone
or delay any date fixed by this Agreement or any other Facility Document for any payment of interest, fees or other amounts due
to the Issuers (or any of them) hereunder or under any other Facility Document;


 


(ii)           reduce
the principal of, or the rate of interest specified herein on any Obligation, or any fees or other amounts payable hereunder or
under any other Facility Document;


 


(iii)          change
the percentage of the Commitments or of the aggregate unpaid amount of the Obligations which is required for the Issuers or any
of them to take any action hereunder;


 


(iv)         amend
this Section or any provision of this Agreement providing for consent or other action by all Issuers;


 


(v)          change
the definition of “Majority Issuers”;


 


(vi)          reduce
the Minimum Collateral Base or amend any component definition thereof that would have the effect of reducing the Minimum Collateral
Base; or


 


(vii)         increase
the Facility Amount;


 


provided, however,
that no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent or the Collateral Agent, as
applicable, affect the rights or duties of the Administrative Agent or the Collateral Agent under this Agreement or any other Facility
Document.


 


Notwithstanding the
foregoing, (x) the consent of the Issuers shall not be required for any amendment (i) to cure any mutually identified
ambiguity or correct any mutually identified mistake or (ii) 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
(y) 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 however, that, if any amendment to Schedule I
attached hereto shall cause the Facility Amount to exceed $874,000,000, such amendment shall be subject to the consent requirement
under clause (vii) above.


 






    28


     


    

 


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.


 


Notwithstanding anything
herein to the contrary, during such period as an Issuer is a Defaulting Issuer, to the fullest extent permitted by applicable law,
such Defaulting Issuer shall not be entitled to 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 16 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.


 


17.          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 17. The provisions of this Section 17 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.


 






    29


     


    

 


(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 17 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 UST Assets under
Section 6(a), if necessary, and (ii) the duties under Section 6(d)(i) and Section 6(d)(ii) of
this 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 16) 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.


 






    30


     


    

 


(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 18,
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 15; 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.


 






    31


     


    

 


(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 17 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.

costs and expenses of the Agents and the Issuers (including reasonable fees and disbursements of Latham & Watkins LLP,

execution and delivery of this Agreement and all Letters of Credit, as well as in connection with the enforcement of, and preservation
of rights under, and ongoing advice, administration, and any modifications or amendments with respect to, this Agreement.


 


20.          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. No waiver or approval by any Agent or any Issuer shall,
except as may be otherwise stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval
hereunder shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law. None of any Agent, any Issuer nor any of their respective Related
Parties shall be liable for any loss of any or all of the Collateral in the absence of gross negligence, fraud or willful misconduct
(as determined by a court of competent jurisdiction in a final and non- appealable decision) on the part of any such person or
entity.


 


21.          Successors
and Assigns. This Agreement shall be binding upon each party hereto and its successors and permitted assigns and shall inure
to the benefit of and be enforceable by each party hereto, its successors and permitted assigns. The Applicant shall not transfer
or otherwise assign any of its obligations under this Agreement and any assignment in violation of this Section 21
shall be null and void. Each Issuer may transfer or otherwise assign its rights and obligations under this Agreement to one or
more assignees (other than any natural person, the Applicant or any of the Applicant’s affiliates); provided that
each of the Administrative Agent and the Applicant must give its prior written consent to such assignment (which consent shall
not be unreasonably withheld or delayed); provided that the consent of the Applicant shall not be required to any such
assignment (i) during the continuance of any Event of Default or (ii) to any affiliate of such Issuer or to any other
Issuer or any affiliate of another Issuer.


 






    33


     


    

 


The Administrative
Agent, acting solely for this purpose as a non-fiduciary agent of the Applicant, shall maintain at one of its offices in the United
States a copy of each assignment delivered to it and a register for the recordation of the names and addresses of the Issuers,
and principal amounts (and stated interest) of the drawings on each Letter of Credit issued by, each Issuer pursuant to the terms
hereof from time to time (the “Register”). 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.


 


22.          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.


 


23.          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 23 are in addition to other rights and remedies (including, without limitation,
other rights of set-off) that any Issuer may have.


 


24.          Counterparts.
This Agreement may be executed in counterparts, each of which when so executed shall be deemed to be an original and all of which
when taken together shall constitute one and the same instrument. Any signature to this Agreement or any notice or other document
delivered in connection herewith may be delivered by electronic mail (including pdf) or any electronic signature complying with
the Electronic Signatures in Global and National Commerce Act, the New York Electronic Signature and Records Act or the Uniform
Electronic Transaction Act, or other transmission method, and any counterpart so delivered shall be deemed to have been duly and
validly delivered and be valid and effective for all purposes to the fullest extent permitted by applicable law. For the avoidance
of doubt, the foregoing also applies to any amendment, extension or renewal of this Agreement.


 


Each party hereto represents
and warrants to the other party hereto that it has the corporate capacity and authority to execute this Agreement through electronic
means and that there are no restrictions for doing so in that party’s constitutive documents.


 


25.          Governing
Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
