 (f) The Agent shall promptly notify each bidding Lender by telecopy whether or not its Competitive Bid has been accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each successful
bidder will thereupon become bound, subject to the terms and conditions hereof, to make the Competitive Loan in respect of which its Competitive Bid has been accepted. 
 (g) If the Agent shall elect to submit a Competitive Bid in its capacity as a Lender, it shall submit such Competitive Bid directly to the applicable Borrower at least one quarter of an hour earlier than
the time by which the other Lenders are required to submit their Competitive Bids to the Agent pursuant to paragraph (c) of this Section. 
 2.5. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to each Borrower from time to time during the period from
and including the Closing Date and prior to the Availability Termination Date for such Borrower; provided that after giving effect thereto and to any repayments of outstanding Obligations made with proceeds of such Swingline Loans
(i) the aggregate principal amount of the outstanding Swingline Loans shall not exceed $40,000,000, (ii) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment, (iii) the Revolving Credit Exposure of any
Lender shall not exceed its Commitment and (iv) the Borrower Credit Exposure of the Borrower requesting any such Swingline Loan shall not exceed the Borrower Sublimit for such Borrower; provided that the Swingline Lender shall not be
required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, each Borrower may, severally and not jointly with the other Borrower, borrow, prepay
and reborrow Swingline Loans at any time prior to the Availability Termination Date for such Borrower. 

  
 27 

 (b) To request a Swingline Loan, a Borrower shall notify the Agent of such request by
telephone not later than 3:00 p.m., New York City time, on the day of the proposed Swingline Loan. Each such telephonic notice shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile to the Agent of an executed written
notice. Each such telephonic and written notice shall specify the requested date (which shall be a Business Day) and the amount of the requested Swingline Loan and the location and number of the account of the Borrower to which funds are to be
disbursed or, in the case of any Swingline Loan requested to finance the reimbursement of an LC Disbursement as provided in Section 2.6(e), the identity of the Issuing Bank that has made such LC Disbursement. Promptly following the receipt of a
notice in accordance with this Section, the Agent shall advise the Swingline Lender of the details thereof. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a wire transfer to the account specified in such
notice or to the applicable Issuing Bank, as the case may be. 
 (c) The Swingline Lender may by written notice given to the
Agent not later than 10:00 a.m., New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount
of the Swingline Loans in which the Lenders will be required to participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Pro Rata Share of such Swingline Loan
or Loans. Each Lender hereby absolutely and unconditionally agrees to pay, upon receipt of notice as provided above, to the Agent, for the account of the Swingline Lender, such Lender’s Pro Rata Share of such Swingline Loan or Loans. Each
Lender acknowledges and agrees that, in making any Swingline Loan, the Swingline Lender shall be entitled to rely, and shall not incur any liability for relying, upon the representation and warranty of the applicable Borrower deemed made pursuant to
Section 4.2, unless, at least one Business Day prior to the time such Swingline Loan was made, the Required Lenders shall have notified the Swingline Lender (with a copy to the Agent) in writing that, as a result of one or more events or
circumstances described in such notice, one or more of the conditions precedent set forth in Section 4.2.1 or 4.2.2 would not be satisfied if such Swingline Loan were then made (it being understood and agreed that, in the event the Swingline
Lender shall have received any such notice, it shall have no obligation to make any Swingline Loan until and unless it shall be satisfied that the events and circumstances described in such notice shall have been cured or otherwise shall have ceased
to exist). Each Lender further acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the
occurrence and continuance of any Default or Unmatured Default or any reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply
with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.11 with respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis
mutandis, to the payment obligations of the Lenders pursuant to this paragraph), and the Agent shall promptly remit to the Swingline Lender the amounts so received by it from the Lenders. The Agent shall notify the applicable Borrower of any
participations in any Swingline Loan acquired pursuant to this 

  
 28 

 
paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the applicable
Borrower (or other Person on behalf of such Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Agent; any such amounts received by the
Agent shall be promptly remitted by the Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid
to the Swingline Lender or to the Agent, as applicable, if and to the extent such payment is required to be refunded to the applicable Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not
constitute a Loan and shall not relieve the applicable Borrower of its obligation to repay such Swingline Loan. 
 2.6.
Letters of Credit. 
 (a) General. Subject to the terms and conditions set forth herein, (i) the Borrowing
Subsidiary may request the issuance of Letters of Credit for its own account or jointly for its own account and the account of any of its subsidiaries (in which case the Borrowing Subsidiary shall be solely responsible for all payments due hereunder
in respect of such Letters of Credit notwithstanding any listing of any subsidiary of the Borrowing Subsidiary as an account party or applicant with respect to such Letters of Credit) and (ii) the Company may request the issuance of Letters of
Credit for its own account or jointly for its own account and the account of any of its subsidiaries other than the Borrowing Subsidiary and its subsidiaries (in which case the Company shall be solely responsible for all payments due hereunder in
respect of such Letters of Credit notwithstanding any listing of any subsidiary of the Company as an account party or applicant with respect to such Letters of Credit), in each case in a form reasonably acceptable to the Agent and the applicable
Issuing Bank, at any time and from time to time prior to the earlier of the Availability Termination Date for such Borrower and the LC Commitment Termination Date for such Issuing Bank. Each Existing Letter of Credit shall be deemed, for all
purposes of this Agreement (including paragraphs (d) and (e) of this Section), to be a Letter of Credit issued hereunder for the account of the applicable Borrower thereunder. 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 a Borrower to, or entered into by a Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and
conditions of this Agreement shall control. The Borrowing Subsidiary, in the case of clause (i) above, and the Company, in the case of clause (ii) above, unconditionally and irrevocably agrees that, in connection with any Letter of Credit
referred to in the applicable clause, it will be fully responsible for the reimbursement of LC Disbursements, the payment of interest thereon and the payment of LC Participation Fees and other fees due under Section 2.8.2 to the same extent as
if it were the sole account party in respect of such Letter of Credit (the Borrowing Subsidiary and the Company each hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of any of its
subsidiaries that shall be a joint account party with it in respect of any such Letter of Credit). 
 (b) Notice of Issuance,
Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the applicable Borrower shall hand deliver or telecopy (or transmit

  
 29 

 
by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Agent (reasonably in advance of the requested
date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension
(which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the account party or account parties with respect to such Letter
of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit, together, in the case of a request for an issuance of a Letter of Credit, with
draft language for such Letter of Credit reasonably acceptable to the applicable Issuing Bank. If requested by the applicable Issuing Bank, such Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in
connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit, such Borrower shall be deemed to represent and
warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the Aggregate Outstanding Credit Exposure will not exceed the Aggregate Commitment, (ii) the Revolving Credit Exposure of any Lender will not exceed
its Commitment, (iii) the Borrower Credit Exposure of the Borrower requesting such Letter of Credit will not exceed the Borrower Sublimit of such Borrower, (iv) the portion of the LC Exposure attributable to Letters of Credit issued by the
applicable Issuing Bank will not, unless such Issuing Bank shall so agree, exceed the LC Commitment of such Issuing Bank and (v) the LC Exposure will not exceed the greater of (A) $250,000,000 and (B) 25% of the Aggregate Commitment
as then in effect. Notwithstanding the foregoing, no Issuing Bank shall be required to issue any Letter of Credit if (x) any order, judgment or decree of any governmental authority shall enjoin or restrain, or by its terms purport to enjoin or
restrain, such Issuing Bank from issuing such Letter of Credit, (y) any applicable law or any order, request or directive (whether or not having the force of law) of any governmental authority with jurisdiction over such Issuing Bank shall
prohibit, or request that such Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or impose upon such Issuing Bank any restriction, reserve or capital requirement with respect to such Letter
of Credit not in effect on the Closing Date for which such Issuing Bank is not otherwise compensated (or assured to its satisfaction that it will be compensated) hereunder or any unreimbursed loss, cost or expense not applicable to such Issuing Bank
on the Closing Date, which such Issuing Bank deems in good faith to be material to it and for which such Issuing Bank is not otherwise compensated (or assured to its satisfaction that it will be compensated) hereunder or (z) for Letters of
Credit to be issued jointly for the account of either Borrower and any of its subsidiaries in accordance with Section 2.6(a), the applicable Issuing Bank has not received documentation that it shall have reasonably requested in order to comply
with its obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the USA Patriot Act, with respect to such subsidiaries. If the Required Lenders notify the Issuing Banks that a Default
exists with respect to a requesting Borrower and instruct the Issuing Banks to suspend the issuance, amendment, renewal or extension of Letters of Credit for the account of such Borrower, no Issuing Bank shall issue, amend, renew or extend any
Letter of Credit for the account of such Borrower or the Company without the consent of the Required Lenders until such notice is withdrawn by the Required Lenders (and each Lender that shall have delivered such notice agrees promptly to withdraw it
at such time as no Default exists). 

  
 30 

 (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five
Business Days prior to earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for the applicable Issuing Bank; provided that any Letter of Credit may contain customary automatic renewal provisions
agreed upon by the applicable Borrower and the applicable Issuing Bank pursuant to which the expiration date of such Letter of Credit shall automatically be extended for a period of up to 12 months (but not to a date later than the date that is five
Business Days prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, unless otherwise permitted pursuant to the immediately succeeding proviso), subject to a right on the
part of such Issuing Bank to prevent any such renewal from occurring by giving notice to the beneficiary in advance of any such renewal; provided, further that, with the prior consent of the Agent and the applicable Issuing Bank, a
Letter of Credit may be issued or extended with an expiration date beyond the fifth Business Day prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, in which case the
applicable Borrower shall deposit on or prior to the date 90 days prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, in an account with such Issuing Bank, for the
benefit of the Lenders and such Issuing Bank, as cash collateral pursuant to documentation reasonably satisfactory to the Agent and such Issuing Bank, an amount in cash equal to 101% of the aggregate amount of all outstanding Letters of Credit
issued for its account by such Issuing Bank that have an expiration date later than the fifth Business Day prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank.

 (d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount
thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal
to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Agent, for
the account of such Issuing Bank, such Lender’s Pro Rata Share of each LC Disbursement made by such Issuing Bank and not reimbursed by the applicable Borrower on the date due as provided in paragraph (e) of this Section, or of any
reimbursement payment required to be refunded to the applicable Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and
unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
 (e) Reimbursement.
If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower for the account such Letter of Credit was issued, severally and not 

  
 31 

 
jointly with the other Borrower, shall reimburse such LC Disbursement by paying to the Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date
that such LC Disbursement is made, if such Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by such Borrower prior to such time on such date,
then not later than 12:00 noon, New York City time, on (i) the Business Day that such Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day
immediately following the day that such Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $1,000,000, such Borrower may, subject to
the conditions to borrowing set forth herein, request in accordance with Section 2.1 or 2.5 that such payment be financed with a Floating Rate Advance or a Swingline Loan to such Borrower in an equivalent amount and, to the extent so financed,
such Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Floating Rate Advance or Swingline Loan. If such Borrower fails to make such payment when due, the Agent shall notify each Lender of the
applicable LC Disbursement, the payment then due from such Borrower in respect thereof and such Lender’s Pro Rata Share thereof. Promptly following receipt of such notice, each Lender shall pay to the Agent its Pro Rata Share of the payment
then due from such Borrower, in the same manner as provided in Section 2.11 with respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent
shall promptly pay to such Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Agent of any payment from such Borrower pursuant to this paragraph, the Agent shall distribute such payment to such Issuing
Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to
reimburse an Issuing Bank for any LC Disbursement (other than the funding of a Floating Rate Advance or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve such Borrower of its obligation to reimburse such LC
Disbursement. 
 (f) Obligations Absolute. Each Borrower’s obligation to reimburse LC Disbursements as provided in
paragraph (e) of this Section in respect of Letters of Credit issued for its account shall be several and not joint with the other Borrower, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with
the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other
document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against
presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of
this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, such Borrower’s obligations hereunder. None of the Agent, the Lenders or the Issuing Banks, or any of their respective affiliates, directors,
officers or employees, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances
referred to in the preceding sentence), or any error, omission, interruption, loss or 

  
 32 

 
delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error
in interpretation of technical terms or any consequence arising from causes beyond the control of the applicable Issuing Bank; provided that the foregoing shall not be construed to excuse an Issuing Bank from liability to a Borrower to the
extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by such Borrower that are caused by such Issuing Bank’s
wrongful honor or rejection of any drawing under such Letter of Credit to the extent arising out of the Issuing Bank’s gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction). In furtherance of the
foregoing and without limiting the generality thereof, but subject to any non-waivable provisions of the laws and/or other rules to which a Letter of Credit is subject, the parties agree that, with respect to documents presented which appear on
their face to be in substantial compliance with the terms of a Letter of Credit, an Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any
notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 

(g) Disbursement Procedures. The applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents
purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Agent and the applicable Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Bank has
made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve such Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC
Disbursement. 
 (h) Interim Interest. If an Issuing Bank shall make any LC Disbursement in respect of any Letter of
Credit, then, unless the Borrower for the account of which such Letter of Credit was issued shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and
including the date such LC Disbursement is made to but excluding the date that such Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Floating Rate Advances; provided that, if such Borrower fails to reimburse
such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.14 shall apply. Interest accrued pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on and after
the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment. 

(i) Cash Collateralization. If (i) a Default under Section 7.2 with respect to a Borrower shall occur and be continuing
or (ii) any other Default with respect to a Borrower shall occur and be continuing and the Required Lenders shall have terminated the Commitments insofar as they are available to such Borrower or accelerated the maturity of any Loans of such
Borrower, in either case as a result of such Default (and unless and until any such termination or acceleration has been rescinded), then on the Business Day that such Borrower receives notice from the Agent or the Required Lenders (or, if the
maturity of the Loans has been accelerated, Lenders with LC Exposures representing greater than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, such Borrower shall deposit in an account

  
 33 

 
with the Agent, in the name of the Agent and for the benefit of the Lenders, an amount in cash equal to 101% of the portion of the LC Exposure as of such date attributable to Letters of Credit
issued for the account of such Borrower; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind,
upon the occurrence of any Default with respect to such Borrower described in Section 7.6 or 7.7. Such deposit shall be held by the Agent as collateral for the payment and performance of the Obligations of such Borrower under this Agreement.
The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made only if and to the extent
requested by such Borrower and then only at the option and sole discretion of the Agent, and all at such Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in
such account. Moneys in such account shall be applied by the Agent to reimburse each Issuing Bank for LC Disbursements under outstanding Letters of Credit issued for the account of such Borrower for which it has not been reimbursed and, to the
extent not so applied, shall be held for the satisfaction of future reimbursement obligations under Letters of Credit issued for the account of such Borrower or, if the maturity of the Loans has been accelerated (but subject to the consent of such
Lenders with LC Exposures representing greater than 50% of the total LC Exposure), be applied to satisfy other Obligations of such Borrower under this Agreement. If either Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of any event specified in clause (i) or (ii) above with respect to such Borrower, such amount (to the extent not applied as aforesaid) shall be returned to such Borrower within three Business Days after all
Defaults with respect to such Borrower have been cured or waived and, if Loans or other Obligations (other than any unasserted contingent indemnity claims) of such Borrower have been accelerated, all such Loans and other Obligations of such Borrower
have been repaid (or such acceleration has been rescinded). If at any time the cash collateral of either Borrower shall exceed 101% of such portion of the LC Exposure as of such date attributable to Letters of Credit issued for the account of such
Borrower, the Agent shall apply such excess funds to the payment of such Borrower’s Obligations or (x) if no such Obligations are then due and owing and no Default with respect to such Borrower shall exist, shall release such excess funds
to such Borrower or (y) if no such Obligations are outstanding (other than contingent Obligations in respect of Letters of Credit which are fully collateralized and unasserted contingent indemnification claims), such excess amount shall be
released to such Borrower notwithstanding the existence of a Default in respect of such Borrower. 
 (j) Designation of
Additional Issuing Banks; Termination of Appointment of Issuing Banks. From time to time, the Borrowers may by notice to the Agent and the Lenders designate as additional Issuing Banks one or more Lenders that agree to serve in such capacity as
provided below. The acceptance by a Lender of any appointment as an Issuing Bank hereunder shall be evidenced by an agreement (an “Issuing Bank Agreement”), which shall be in a form satisfactory to the Borrowers and the Agent, shall
set forth the LC Commitment of such Lender and shall be executed by such Lender, the Borrowers and the Agent and, from and after the effective date of such agreement, (i) such Lender shall have all the rights and obligations of an Issuing Bank
under this Agreement and the other Loan Documents and (ii) references herein and in the other Loan Documents to the term “Issuing Bank” shall be deemed to include such Lender in its capacity as an Issuing Bank. If the Commitment
Termination Date shall be extended beyond the 

  
 34 

 
LC Commitment Termination Date of any Issuing Bank that is a Declining Lender, the appointment of such Issuing Bank shall be terminated effective as of the Existing Commitment Termination Date,
at which time the Borrowers shall pay any unpaid fees accrued for the account of the terminated Issuing Bank pursuant to Section 2.8.2. Notwithstanding the effectiveness of any such termination, the terminated Issuing Bank shall remain a party
hereto and shall continue to have all rights as an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such termination, but shall not issue any additional Letters of Credit. 

(k) Issuing Bank Reports to the Agent. Unless otherwise agreed by the Agent, each Issuing Bank shall, in addition to its
notification obligations set forth elsewhere in this Section, report in writing to the Agent (i) upon the reasonable request of the Agent, periodic activity (for such period or recurrent periods as shall be requested by the Agent) in respect of
Letters of Credit issued by such Issuing Bank, including all issuances, extensions, amendments and renewals, all expirations and cancelations and all disbursements and reimbursements, (ii) reasonably prior to the time that such Issuing Bank
issues, amends, renews or extends any Letter of Credit, the Borrower for the account of which such Letter of Credit is to be issued, the date of such issuance, amendment, renewal or extension, and the stated amount of the Letters of Credit issued,
amended, renewed or extended by it for the account of each Borrower and outstanding after giving effect to such issuance, amendment, renewal or extension (and whether the amounts thereof shall have changed), (iii) on each Business Day on which
such Issuing Bank makes any LC Disbursement, the date and amount of such LC Disbursement and the Letter of Credit to which it relates and (iv) on any Business Day on which a Borrower fails to reimburse an LC Disbursement required to be
reimbursed to such Issuing Bank on such day, the date of such failure and the amount of such LC Disbursement. 
 (l) LC
Exposure Determination. For all purposes of this Agreement, the amount of a Letter of Credit that, by its terms or the terms of any document related thereto, provides for one or more automatic increases in the stated amount thereof shall be
deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at the time of determination. 

2.7. Types of Advances. Revolving Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof,
selected by the applicable Borrower in accordance with Sections 2.11 and 2.12. Competitive Loans may be Eurodollar Rate Advances or Fixed Rate Advances, or a combination thereof, selected by the applicable Borrower in accordance with
Section 2.4. Each Swingline Loan shall be a Floating Rate Advance. 
 2.8. Facility Fee; Letter of Credit Fees;
Reductions in Aggregate Commitment and Borrower Sublimits. 
 2.8.1 Facility Fee. Subject to
Section 2.25, each Borrower agrees, severally and not jointly with the other Borrower, to pay to the Agent for the account of each Lender a facility fee (the “Facility Fee”) at a per annum rate equal to such Borrower’s
Applicable Fee Rate on its Contribution Percentage of such Lender’s Commitment (whether used or unused) from and including the Closing Date to and including the Availability 

  
 35 

 
Termination Date for such Borrower, payable quarterly in arrears on each Payment Date hereafter and on the Availability Termination Date for such Borrower; provided, that if any Lender
continues to have Revolving Credit Exposure attributable to such Borrower hereunder after the Availability Termination Date for such Borrower (excluding any Revolving Credit Exposure in respect of LC Exposure which is cash collateralized hereunder),
then the Facility Fee shall continue to accrue on the aggregate principal amount of such Revolving Credit Exposure until such Lender ceases to have any such Revolving Credit Exposure, and shall be payable on demand. 

2.8.2 Letter of Credit Fees. Each Borrower agrees, severally and not jointly with the other Borrower, to pay
(i) to the Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit issued for the account of such Borrower (the “LC Participation Fee”), which shall accrue at the
Applicable Fee Rate on the average daily amount of that portion of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) attributable to Letters of Credit issued for the account of such Borrower
during the period from and including the Closing Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any such LC Exposure, and (ii) to each Issuing Bank
a fronting fee, which shall accrue at the rate or rates per annum separately agreed upon between such Borrower and such Issuing Bank on the average daily amount of the LC Exposure attributable to Letters of Credit issued by such Issuing Bank for the
account of such Borrower (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Closing Date to but excluding the later of the date of termination of such Issuing Bank’s LC
Commitment and the date on which there ceases to be any such LC Exposure attributable to Letters of Credit issued by such Issuing Bank for such Borrower, as well as each Issuing Bank’s standard fees with respect to the issuance, amendment,
renewal or extension of any Letter of Credit issued by such Issuing Bank for the account of such Borrower or processing of drawings thereunder. LC Participation Fees and fronting fees accrued through and including the last day of March, June,
September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Closing Date; provided that all such fees accrued for the account of such Borrower
shall be payable on the Availability Termination Date for such Borrower and any such fees accruing after the Availability Termination 

  
 36 

 
Date for such Borrower shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this paragraph shall be payable promptly upon receipt of an invoice therefor in reasonable
detail. 
 2.8.3 Termination of and Reductions in Aggregate Commitment and Borrower Sublimits. The
Commitments will automatically terminate on the Commitment Termination Date. The Company (on behalf of itself and the Borrowing Subsidiary) may permanently reduce the Aggregate Commitment (with or without reducing either Borrower Sublimit), and
(without limiting the foregoing) the Borrowing Subsidiary or the Company, as applicable, may permanently reduce its respective Borrower Sublimit (with or without reducing the Aggregate Commitment), in each case, in whole or in part and without
penalty or premium, ratably among the Lenders in integral multiples of $5,000,000, upon at least three (3) Business Days’ written notice to the Agent, which notice shall specify, as applicable (a) the aggregate amount of any such
reduction and/or (b) the individual amount by which the applicable Borrower Sublimit shall be reduced, provided, however, that (i) the amount of the Aggregate Commitment may not be reduced below the Aggregate Outstanding
Credit Exposure and (ii) the Borrower Sublimit of either Borrower may not be reduced below the Borrower Credit Exposure of such Borrower. Any reduction of the Aggregate Commitment under this Section (other than the first sentence hereof) shall
reduce ratably the Commitments of all the Lenders. 
 2.9. Minimum Amount of Each Advance. Each Eurodollar Advance shall
be in the minimum amount of $5,000,000 (and in a multiple of $1,000,000 if in excess thereof), and each Floating Rate Advance shall be in the minimum amount of $5,000,000 (and in a multiple of $1,000,000 if in excess thereof); provided,
however, that (i) any Floating Rate Advance to a Borrower may be in the amount of the Available Aggregate Commitment and (ii) any Floating Rate Advance to a Borrower may be in the amount equal to the lesser of the Available
Aggregate Commitment and the amount by which the Borrower Sublimit of such Borrower exceeds the Borrower Credit Exposure of such Borrower. Each Swingline Loan shall be in an amount that is an integral multiple of $500,000 and not less than
$1,000,000. 
 2.10. Optional Principal Payments. Each Borrower may from time to time pay, without penalty or premium,
all outstanding Floating Rate Advances of such Borrower, or any portion of such outstanding Floating Rate Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (or, if less, the remaining
outstanding principal amount of such Borrower’s Floating Rate Advances), upon at least one (1) Business Day’s prior notice to the Agent. Each Borrower may from time to time pay, subject to the payment of any funding indemnification
amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances of such Borrower, or any portion of such outstanding 

  
 37 

 
Eurodollar Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (or, if less, the remaining outstanding principal amount of such
Borrower’s Eurodollar Advances), upon at least three (3) Business Days’ prior notice to the Agent; provided that no Competitive Loan may be prepaid without the consent of the applicable Lender. Each Borrower may from time to
time pay, without penalty or premium, any outstanding Swingline Loan upon giving notice thereof to the Swingline Lender not later than 12:00 noon, New York City time, on the date of prepayment. Any optional payment of Advances (other than
Competitive Loans and Swingline Loans) under this Section shall be applied ratably to the Advances (other than Competitive Loans and Swingline Loans) of all the Lenders. 
 2.11. Method of Selecting Types and Interest Periods for New Revolving Advances; Funding of Loans. The applicable Borrower shall select the Type of each Revolving Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable thereto; provided that there shall be no more than five (5) Interest Periods in effect with respect to all of the Revolving Loans of any single Borrower at any time, unless such limit
has been waived by the Agent in its sole discretion. The applicable Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 11:30 a.m. (New York time) on the Borrowing Date of each Floating Rate
Advance or on the third Business Day before the Borrowing Date for each Eurodollar Advance, specifying: 
  

	 	(i)	the Borrower requesting such Advance, 

  

	 	(ii)	the Borrowing Date, which shall be a Business Day, of such Advance, 

  

	 	(iii)	the aggregate amount of such Advance, 

  

	 	(iv)	the Type of Advance selected, and 

  

	 	(v)	in the case of each Eurodollar Advance, the Interest Period applicable thereto. 

 The Agent shall provide written notice of each request for borrowing under this Section 2.11 by 12:30 p.m. (New York time) on the Borrowing Date for each Floating Rate Advance or on the third
Business Day prior to the Borrowing Date for each Eurodollar Advance, as applicable. Not later than 2:00 p.m. (New York time) on each Borrowing Date, each Lender shall make available its Revolving Loan or Revolving Loans in Federal or other funds
immediately available in New York to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Lenders available to such Borrower at the Agent’s aforesaid address. 

2.12. Conversion and Continuation of Outstanding Revolving Advances; No Conversion or Continuation of Eurodollar Advances After
Default. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.12 or are repaid in accordance with Section 2.10.
Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Eurodollar Advance with an Interest Period of
30 days (unless such conversion would otherwise be prohibited hereunder, in which case such Eurodollar 

  
 38 

 
Advance shall be converted into a Floating Rate Advance) unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.10 or (y) the applicable Borrower shall
have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance either continue as a Eurodollar Advance for the same or another Interest Period or be converted to
a Floating Rate Advance. Subject to the terms of Section 2.9, a Borrower may elect from time to time to convert all or any part of an Advance of any Type into any other Type or Types of Advances; provided that any conversion of any
Eurodollar Advance shall be made on, and only on, the last day of the Interest Period applicable thereto. Notwithstanding anything to the contrary contained in this Section 2.12, during the continuance of a Default with respect to a Borrower,
the Agent may (or shall at the direction of the Required Lenders), by notice to such Borrower, declare that no Advance of such Borrower may be made, converted or continued as a Eurodollar Advance. The applicable Borrower shall give the Agent
irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance to a Eurodollar Advance, continuation of a Eurodollar Advance, or conversion of a Eurodollar Advance to a Floating Rate Advance
not later than 11:00 a.m. (New York time) at least three (3) Business Days prior to the date of the requested conversion or continuation, specifying: 
  

	 	(i)	the requested date, which shall be a Business Day, of such conversion or continuation, 

 

	 	(ii)	the aggregate amount and Type of the Advance to be converted or continued, and 

 

	 	(iii)	the amount of the Advance to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto.

 This Section shall not apply to Competitive Loans and Swingline Loans, which may not be converted or continued. 

2.13. Interest Rates, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each
day from and including the date such Advance is made, to, but excluding, the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.12, as applicable, at a rate per annum equal to the Floating Rate applicable to such
Borrower for such day. Each Swingline Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Loan is made to but excluding the date it is paid, at a rate per annum equal to the Floating
Rate applicable to such Borrower for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance and on any Swingline Loan will take effect simultaneously with each change in the Alternate Base
Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of each Interest Period applicable thereto to (but not including) the earlier of the last day of such Interest Period or
the date it is paid in accordance with Section 2.10, at the applicable Eurodollar Rate as determined by the Agent as applicable to such Borrower’s Eurodollar Advance based upon the applicable Borrower’s selections under Sections 2.11
and 2.12 and otherwise in accordance with the terms hereof. Each Fixed Rate Advance shall bear interest at the Fixed Rate applicable thereto. 

  
 39 

 2.14. Rates Applicable After Default. Notwithstanding the foregoing, if any principal
of any Loan is not paid when due, or if any interest on any Loan or any fee or other amount payable by either Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise (in each case, after giving effect to
any applicable grace period with respect to such payment), such overdue amount shall bear interest, commencing on the day after such amount shall have become due in the case of principal and on the second Business Day after such amount shall have
become due (in each case, after giving effect to any applicable grace period with respect to such payment) in the case of other amounts, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any
Loan, 2% per annum plus the rate otherwise applicable to such Loan as provided in Section 2.13 or (ii) in the case of any other amount, 2% per annum plus the rate applicable to Floating Rate Advances as provided in
Section 2.13. 
 2.15. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff,
deduction or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent reasonably in advance of the
date any such payment is required to be made, by 12:00 noon (New York time) on the date when due and shall be applied ratably by the Agent among the Lenders to which such Obligations are owing. Each payment delivered to the Agent for the account of
any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent from
such Lender. The Agent is hereby authorized, at any time when a Default shall have occurred and be continuing, to charge the respective accounts of each Borrower maintained with JPMCB for each payment of principal, interest and fees owed by such
Borrower as such payment becomes due hereunder. 
 2.16. Noteless Agreement; Evidence of Indebtedness. (i) Each
Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan made by such Lender to such Borrower from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time hereunder. 
  

	 	(ii)	The Agent shall also maintain accounts in which it will record (a) the date and the amount of each Loan made to each Borrower hereunder, the Type thereof and the
Interest Period (in the case of a Eurodollar Advance) with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder, (c) the effective date and
amount of each Assignment and Assumption delivered to and accepted by it pursuant to Section 12.1 and the parties thereto, (d) the amount of any sum received by the Agent hereunder from each Borrower and each Lender’s share thereof,
and (e) all other appropriate debits and credits as provided in this Agreement, including all fees, charges, expenses and interest. 

  

	 	(iii)	 The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence
absent manifest error of the existence and amounts of the Obligations therein recorded; provided, however, that the failure 

  
 40 

	 	
of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of such Borrower to repay the Obligations in accordance with their terms.

  

	 	(iv)	Any Lender may request that its Loans be evidenced by a promissory note in substantially the form of Exhibit E (a “Note”). In such event, the
applicable Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to
Section 12.1) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be
evidenced as described in paragraphs (i) and (ii) above. 

 2.17. Telephonic Notices. Each
Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good
faith believes to be acting on behalf of such Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. Each Borrower agrees to
deliver promptly to the Agent a written confirmation, signed by an Authorized Officer, of each telephonic notice. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the
Agent and the Lenders shall govern absent manifest error. 
 2.18. Interest Payment Dates; Interest and Fee Basis.
Interest accrued on each Floating Rate Advance shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the Closing Date, on any date on which such Floating Rate Advance is prepaid, whether due to
acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of each applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or
otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest accrued on each Fixed
Rate Loan shall be payable on the last day of the Interest Period applicable to the Advance of which such Loan is a part and, in the case of a Fixed Rate Advance with an Interest Period of more than 90 days’ duration (unless otherwise specified
in the applicable Competitive Bid Request), each day prior to the last day of such Interest Period that occurs at intervals of 90 days’ duration after the first day of such Interest Period, and any other dates that are specified in the
applicable Competitive Bid Request as dates for payment of interest with respect to such Advance. Interest accrued on each Swingline Loan shall be payable in arrears on the day that such Loan is repaid or is required to be paid. Interest accrued on
any Advance that is not paid when due shall be payable on demand and on the date of payment in full. Interest on Eurodollar Advances, Fixed Rate Loans and fees hereunder shall be calculated for actual days elapsed on the basis of a 360-day year.
Interest on Floating Rate Advances and Swingline Loans shall be calculated for actual days elapsed on the basis of a 365/366-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if
payment is received prior to 12:00 noon (New York time) at the place of 

  
 41 

 
payment. If any payment of principal of or interest on an Advance, any fees or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business
Day, such payment shall be made on the next succeeding Business Day and, in the case of principal payment, such extension of time shall be included in computing interest, fees and commissions in connection with such payment. 

2.19. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions; Availability of Loans. Promptly after
receipt thereof, the Agent will notify each Lender in writing of the contents of each Aggregate Commitment or Borrower Sublimit reduction notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The
Agent will notify the applicable Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Borrower and each Lender prompt notice of each change in the
Alternate Base Rate. 
 2.20. Lending Installations. Each Lender may, subject to its obligations under Section 3.7,
book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans and any Notes issued hereunder shall
be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice to the Agent and the Borrowers in accordance with Article XIII, designate replacement or additional Lending Installations through
which Loans will be made by it and for whose account Loan payments are to be made. 
 2.21. Non-Receipt of Funds by the
Agent. Unless the applicable Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or any payment under
Section 2.6(e) or (ii) in the case of a Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The
Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or such Borrower, as the case may be, has not in fact made such payment to the Agent, the
recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent
until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the
relevant Loan or (y) in the case of payment by a Borrower, the interest rate applicable to the relevant Loan. 
 2.22.
Replacement of Lender. If (a) either Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender, (b) any Lender’s obligation to make or continue, or to convert Floating Rate
Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3, (c) any Lender is a Declining Lender, (d) any Lender is a Defaulting Lender or has a direct or indirect parent company that is the subject of a Bankruptcy
Event, (e) any Lender invokes Section 9.2 or (f) any Lender has advised that it will not consent to any waiver or amendment of this Agreement that requires the approval of all the Lenders or all

  
 42 

 
affected Lenders and, upon the replacement of such non-consenting Lender, the Lender replacing such non-consenting Lender shall consent to any such waiver or amendment and such approval (as to
all Lenders or as to all affected Lenders, as applicable) shall be obtained (any Lender subject to any of the foregoing clauses (a), (b), (c), (d), (e) or (f) being an “Affected Lender”), the Borrowers may elect
(i) in the case of the foregoing clauses (a), (b), (d) or (e) (but only if such additional payment continues to be required, such suspension continues to be effective, such Lender continues to be a Defaulting Lender or the direct
or indirect parent company of such Lender continues to be the subject of a Bankruptcy Event or Section 9.2 continues to be invoked), to terminate the Commitment of such Affected Lender (without affecting the Commitments of the other Lenders),
or (ii) in all cases, to replace such Affected Lender and its Commitment (including with one or more Lenders (which may be current Lenders) having lesser, equivalent or greater aggregate Commitments than those of the Affected Lenders being so
replaced); provided that (A) in the case of any termination of the Commitment of an Affected Lender, no Default or Unmatured Default shall have occurred and be continuing at the time of such termination, (B) in the case of any
replacement of an Affected Lender, one or more banks or other entities which are approved by the Borrowers, the Agent, each Issuing Bank and the Swingline Lender (such approval not to be unreasonably withheld or delayed) shall purchase for cash at
face amount the Outstanding Credit Exposure of the Affected Lender pursuant to an Assignment and Assumption substantially in the form of Exhibit C (and, if not already a Lender, shall become a Lender for all purposes under this Agreement) and assume
the Commitment and all obligations of the Affected Lender as of the time of such replacement and comply with the requirements of Section 12.1 applicable to assignments, and (C) in the case of any termination or replacement of the
Commitment of an Affected Lender, each Borrower shall pay to such Affected Lender in immediately available funds on the day of termination or replacement, to the extent not paid by a replacement Lender pursuant to the preceding clause (B), all
principal, interest, fees and other amounts (other than unasserted contingent indemnity obligations) then outstanding or accrued but unpaid for the account of such Affected Lender to the extent constituting Obligations of such Borrower hereunder,
including payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and, except in the case of a Defaulting Lender, an amount, if any, equal to the payment which would have been due to such Lender on the day of such termination or
replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date pursuant to Section 2.10. Notwithstanding the foregoing, the Borrowers may not terminate the Commitment of an Affected Lender if, after giving
effect to such termination, (x) the Aggregate Outstanding Credit Exposure would exceed the Aggregate Commitment (as then in effect giving effect to any increases thereof effected in accordance with the terms hereof) or (y) the Borrower
Credit Exposure of either Borrower would exceed the Borrower Sublimit of such Borrower. 
 2.23. Extension of Commitment
Termination Date. The Company, on behalf of both Borrowers, may, on not more than two occasions during the term of this Agreement, by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders) delivered not fewer
than 45 days, and not more than 60 days, before any anniversary of the Closing Date, request that the Lenders extend the then effective Commitment Termination Date (the “Existing Commitment Termination Date”) for an additional
period of one year, effective as of a date specified in such notice. Each Lender shall, by notice to the Company and the Agent given not later than the 20th day after the date of the Agent’s receipt of the Company’s notice, advise the
Company whether or not it agrees to the requested extension (each Lender agreeing to a 

  
 43 

 
requested extension being called a “Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender
that has not so advised the Company and the Agent by such day shall be deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to a Commitment Termination
Date extension request, then the Commitment Termination Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Existing Commitment Termination Date. The decision of any Lender to agree or withhold agreement to any
extension request shall be at the sole discretion of such Lender. The Commitment of any Declining Lender shall terminate on the Existing Commitment Termination Date. The principal amount of any outstanding Loans made by Declining Lenders, together
with any accrued interest thereon and any accrued fees and other amounts payable to or for the accounts of such Declining Lenders hereunder, shall be due and payable on the Existing Commitment Termination Date, and on the Existing Commitment
Termination Date each Borrower shall also make such other prepayments of its Loans as shall be required in order that, after giving effect to such prepayments and to the termination of the Commitments of, and all payments to, Declining Lenders
pursuant to this sentence, (a) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment, (b) the Revolving Credit Exposure of any Lender shall not exceed its Commitment and (c) the Borrower Credit Exposure
of either Borrower shall not exceed the Borrower Sublimit of such Borrower. Notwithstanding the foregoing, no extension of the Commitment Termination Date shall become effective under this Section unless (i) on the effective date of such
extension, the conditions set forth in Section 4.2 (it being understood and agreed that (A) all references to “Credit Extension Date” therein shall be deemed to refer to such effective date and (B) all references to the
“Closing Date” in (x) Section 4.2.2 as it relates to Sections 5.5, 5.7 and 5.14(ii) and (y) in Sections 5.5, 5.7 and 5.14(ii) shall be deemed to refer to such effective date for purposes of determining satisfaction of the
conditions set forth in Section 4.2 as of such date) shall be satisfied as of such date (as though the effectiveness of such extension were a Credit Extension) and (ii) the Agent shall have received a certificate to that effect dated such
effective date and executed by an Authorized Officer of the Company. 
 2.24. Extension of Borrowing Subsidiary Maturity
Date. The Borrowing Subsidiary may, by notice (a “Maturity Date Extension Request”) to the Agent (which shall promptly deliver a copy to each of the Lenders) given at any time (and from time to time without limitation) not more
than 90 days and not less than 30 days prior to its then-current Maturity Date (the “Existing Maturity Date”), request an extension of such Maturity Date to a date not more than 364 days after the Existing Maturity Date specified in
such notice, but in no event to a date later than the Commitment Termination Date. Each Lender shall, by notice to such Borrowing Subsidiary, the Company and the Agent given not later than the 20th day after the date of the Agent’s receipt of
such Maturity Date Extension Request, advise such Borrowing Subsidiary and the Company whether or not it agrees to the requested extension (and, except as set forth in the following proviso, any Lender that has not so advised such Borrowing
Subsidiary, the Company and the Agent by such day shall be deemed to have declined to agree to such extension); provided, that notwithstanding the foregoing, (i) so long as the Borrowing Subsidiary shall have received FERC authorization
for short-term financings for the period through the requested Maturity Date, then upon written notice thereof to the Agent (either concurrently with the delivery of the Maturity Date Extension Request or at anytime thereafter but prior to the then
effective Maturity Date) and satisfaction of the conditions set forth in the following sentence, each Lender shall be obligated to consent (and shall be deemed to have consented) to such 

  
 44 

 
extension and the Maturity Date for such Borrowing Subsidiary shall be deemed extended to the date requested by the Borrowing Subsidiary in such notice without any further consent or approval of
any Lender, any Issuing Bank or the Agent and (ii) upon the Borrowing Subsidiary’s receipt of the necessary approvals from the Missouri Public Service Commission authorizing such Borrowing Subsidiary to borrow hereunder through the
Commitment Termination Date, then upon written notice thereof to the Agent and satisfaction of the conditions set forth in the following sentence, the Maturity Date for such Borrowing Subsidiary shall automatically be extended to the Commitment
Termination Date without the consent or approval of or any further action by any Lender, any Issuing Bank or the Agent. If requested by the Borrowing Subsidiary, the effectiveness of any such extension shall be confirmed by the Agent in writing to
the Borrowing Subsidiary. Unless otherwise consented to by the Required Lenders, no extension of such Maturity Date pursuant to this Section 2.24 shall become effective unless the Agent shall have received (1) copies of any approvals by
FERC and/or the Missouri Public Service Commission, as applicable, required for such extension and (2) legal opinions (including from Borrowing Subsidiary’s in-house counsel) in substantially the form of those delivered pursuant to
Section 4.1.7 solely as to the fact that any and all FERC, Missouri Public Service Commission and/or other regulatory approvals, as applicable, required to permit borrowings by and Credit Extensions to the Borrowing Subsidiary in the amount of
its Borrower Sublimit through the extended Maturity Date have been obtained (to be in form and substance (to the extent of the limited scope thereof set forth above) reasonably satisfactory to the Agent). 

2.25. Defaulting Lenders. (a) Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a
Defaulting Lender, then the following provisions shall apply: 
  

	 	(i)	Facility Fees shall cease to accrue on the unused portion of such Defaulting Lender’s Commitment. 

 

	 	(ii)	The Commitment and Outstanding Credit Exposure of such Defaulting Lender shall not be included in determining whether the Required Lenders or other requisite Lenders
have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 8.2); provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender
shall require the consent of such Defaulting Lender (in such case, to the extent such Defaulting Lender is an affected Lender). 

  

	 	(iii)	Unless a Default or an Unmatured Default shall have occurred and be continuing, all or any part of such Defaulting Lender’s Swingline Exposure and LC Exposure
shall be reallocated among the non-Defaulting Lenders in accordance with their Pro Rata Shares of the Aggregate Commitment, but only to the extent the sum of all non-Defaulting Lenders’ Outstanding Credit Exposures plus such Defaulting
Lender’s Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments. 

  

	 	(iv)	If the LC Exposure of such Defaulting Lender is reallocated pursuant to clause (iii) above, then the LC Participation Fees payable to the Lenders pursuant to
Section 2.8.2 shall be adjusted in accordance with such reallocation. 

  
 45 

	 	(v)	If (or to the extent) the reallocation described in clause (iii) above cannot, or can only partially, be effected, each Borrower shall within one Business Day
following notice by the Agent (x) first, prepay the Defaulting Lender’s non-reallocated portion of the Swingline Exposure attributable to Swingline Loans made to such Borrower and (y) second, cash collateralize for the
benefit of the Issuing Banks such Borrower’s obligations corresponding to the portion of such Defaulting Lender’s non-reallocated LC Exposure that is attributable to Letters of Credit issued for the account of such Borrower (in each case,
as determined after giving effect to any partial reallocation pursuant to clause (iii) above) in accordance with the procedures set forth in Section 2.6(i) for so long as such LC Exposure is outstanding. 

 

	 	(vi)	If a Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to clause (v) above, such Borrower shall not be required to pay
any fees to such Defaulting Lender pursuant to Section 2.8.2 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized. 

 

	 	(vii)	The Agent shall adjust the allocation of payments hereunder to ensure that a Defaulting Lender does not receive payment in respect of any Loan or LC Disbursement that
it did not fund or to reflect any of the actions or adjustments referred to in this Section 2.25. 

 (b) If
(i) a Bankruptcy Event with respect to the parent company of any Lender shall occur following the date hereof and for so long as such event shall continue or (ii) the Swingline Lender or any Issuing Bank shall have a good faith belief that
any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Swingline Lender shall not be required to fund any Swingline Loan and such Issuing Bank shall not be
required to issue, amend or increase any Letter of Credit, unless the Swingline Lender or such Issuing Bank, as the case may be, shall have entered into arrangements with the applicable Borrower or such Lender reasonably satisfactory to the
Swingline Lender or such Issuing Bank, as the case may be, to mitigate the risk to it in respect of such Lender failing to satisfy its participating interest therein. 
 (c) In the event that the Agent, each Borrower, the Swingline Lender and each Issuing Bank agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting
Lender, then the Swingline Exposure and LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans (other than Competitive Loans and
Swingline Loans) and participations in LC Disbursements of the other Lenders as the Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Pro Rata Share. 

(d) Except as expressly provided in this Section 2.25 in connection with the obligations of the Swingline Lender or the Issuing
Banks, the obligation of each Lender, Issuing Bank and Swingline Lender to fund the full amount of its Commitment and to make Loans, Advances and other extensions of credit hereunder shall not be released or diminished in any respect by any other
Lender becoming a Defaulting Lender. 

  
 46 

 (e) None of the foregoing provisions of this Section 2.25 shall be deemed to effect,
diminish or release any rights, claims or causes of action the Borrowers may have against any Lender that becomes a Defaulting Lender. 
 2.26. Commitment Increases. (a) The Borrowers may from time to time (and more than one time), by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders),
executed by the Borrowers and one or more financial institutions (any such financial institution referred to in this Section being called an “Augmenting Lender”), which may include any Lender, cause new Commitments to be extended by
the Augmenting Lenders or cause the existing Commitments of the Augmenting Lenders to be increased, as the case may be (the aggregate amount of such increase for all Augmenting Lenders on any single occasion being referred to as a
“Commitment Increase”), in an amount for each Augmenting Lender set forth in such notice; provided that (i) the amount of each Commitment Increase shall be not less than $10,000,000, except to the extent necessary to
utilize the remaining unused amount of increase permitted under this Section 2.26(a) and (ii) the Aggregate Commitment shall not exceed $1,200,000,000 after giving effect to the effectiveness of any Commitment Increase. The decision of any
Lender to become an Augmenting Lender shall be at the sole discretion of such Lender. Each Augmenting Lender shall be subject to the approval of the Agent, each Issuing Bank and the Swingline Lender (which approval shall not be unreasonably withheld
or delayed) and shall not be subject to the approval of any other Lenders, and the Company and each Augmenting Lender shall execute all such documentation as the Agent shall reasonably specify to evidence the Commitment of such Augmenting Lender
and/or its status as a Lender hereunder (such documentation in respect of any Commitment Increase together with the notice of such Commitment Increase being referred to collectively as the “Commitment Increase Amendment” in respect
of such Commitment Increase). 
 (b) Upon each Commitment Increase pursuant to this Section, (i) each Lender immediately
prior to such increase will automatically and without further act be deemed to have assigned to each Augmenting Lender providing a portion of such Commitment Increase, and each such Augmenting Lender will automatically and without further act be
deemed to have assumed, a portion of such Lender’s participations hereunder in outstanding Letters of Credit such that, after giving effect to such Commitment Increase and each such deemed assignment and assumption of participations, the
percentage of the aggregate outstanding participations hereunder in Swingline Loans and Letters of Credit held by each Lender (including each such Augmenting Lender) will (subject to Section 2.25) equal such Lender’s Pro Rata Share and
(ii) if, on the date of such Commitment Increase, there are any Revolving Loans outstanding, the parties hereto shall, at the request of the Agent, take actions agreed upon by the Agent and the Company that will result, within a period
acceptable to the Agent and the Company, in the outstanding Revolving Loans being held by the Lenders ratably in accordance with their Commitments. In determining the actions to be taken (which may include the prepayment and reborrowing of all or a
portion of such Revolving Loans and/or the making of Revolving Loans on a non-pro-rata basis by Augmenting Lenders for the balance of Interest Periods in progress and at rates reflecting the Eurodollar Base Rate at the time for loans of such
duration), the Agent and the Lenders will endeavor to minimize breakage costs for which the Borrowers must 

  
 47 

 
compensate the Lenders to the extent practicable without undue complexity or administrative burdens on the Agent or the Lenders. The Agent and the Lenders hereby agree that the minimum borrowing,
pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. 

(c) Commitment Increases and new Commitments created pursuant to this Section 2.26 shall become effective on the date specified in
the notice delivered by the Company pursuant to the first sentence of paragraph (a) above or on such other date as agreed upon by the Company, the Agent and the applicable Augmenting Lenders. 

(d) Notwithstanding the foregoing, no increase in the Commitments (or in any Commitment of any Lender) or addition of an Augmenting
Lender shall become effective under this Section unless (i) on the date of such increase, the conditions set forth in Section 4.2 (it being understood and agreed that (A) all references to “Credit Extension Date” therein
shall be deemed to refer to the date of such Commitment Increase and (B) all references to the “Closing Date” in Sections 5.5, 5.7 and 5.14(ii) shall be deemed to refer to the date of such Commitment Increase) shall be satisfied as of
such date (as though the effectiveness of such increase were a Credit Extension) and the Agent shall have received a certificate to that effect dated such date and executed by an Authorized Officer of the Company, and (ii) the actions referred
to in paragraph (b)(ii) of this Section 2.26 shall have been agreed upon by the Agent and the Company (provided, however, that the prepayment and reborrowing on the date of such Commitment Increase of all Revolving Loans then
outstanding shall be deemed to satisfy the condition specified in this clause (ii)). 
 ARTICLE III 

YIELD PROTECTION; TAXES 
 3.1. Yield Protection. If any Change in Law: 
 3.1.1
subjects any Recipient to any Taxes (other than Indemnified Taxes and Excluded Taxes) on its Loans, Loan principal, Letters of Credit, Commitment or other obligations hereunder, or its deposits, reserves, other liabilities or capital attributable
thereto, or 
 3.1.2 imposes, modifies or deems applicable any reserve, assessment, insurance charge, special
deposit, compulsory loan or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Issuing Bank, any Lender or any applicable Lending Installation (other than reserves and
assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or 

  
 48 

 3.1.3 impose on any Lender, any Issuing Bank or any applicable Lending
Installation or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or such Lending Installation or any Letter of Credit or participation therein, 

and the result of any of the foregoing is to increase the cost to the Agent, such Lender or Issuing Bank or such Lending Installation of making,
converting to, continuing or maintaining its Commitment, any Loan or Letter of Credit or any participation therein or to reduce the amount of any sum received or receivable by the Agent, such Lender or Issuing Bank or such Lending Installation
hereunder, then, within fifteen (15) days after the submission of the written statement required by Section 3.6 by the Agent or such Lender or Issuing Bank or such Lending Installation, the Borrowers shall pay the Agent or such Lender or
Issuing Bank or such Lending Installation such additional amount or amounts as will compensate it for such increased cost or reduction in amount received. 
 3.2. Changes in Capital Adequacy and Liquidity Requirements. If any Lender or Issuing Bank determines that any Change in Law affecting such Lender or Issuing Bank or any Lending Installation of
such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding capital or liquidity requirements has had or would have the effect of reducing the rate of return on such Lender’s or Issuing Bank’s capital or on
the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitment of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender,
or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such
Lender’s or Issuing Bank’s policies and the policies of such Lender’s or Issuing Bank’s holding company with respect to capital adequacy or liquidity), then, within fifteen (15) days after the submission of the written
statement required by Section 3.6 by such Lender or Issuing Bank, the Borrowers shall pay such Lender or Issuing Bank the amount applicable to such Borrower necessary to compensate such Lender or Issuing Bank or such Lender’s or Issuing
Bank’s holding company for any such reduction suffered. 
 3.3. Availability of Types of Advances. If prior to the
first day of any Interest Period, the Agent shall give telecopy or telephonic notice thereof to the Borrowers and the Lenders that: 
 (a) the Agent shall have determined (which determination shall be conclusive and binding upon the Borrowers) that, by reason of circumstances affecting the relevant market, adequate and reasonable means
do not exist for ascertaining the interest rate applicable to Eurodollar Advances for such Interest Period, or 
 (b) the Agent
shall have received notice from the Required Lenders that the interest rate for Eurodollar Advances determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively determined
by such Lenders) of making or maintaining their affected Eurodollar Advances during such Interest Period, then (x) any Eurodollar Advances requested to be made on the first day of such Interest Period shall be made as Floating Rate Advances,
(y) any Floating Rate 

  
 49 

 
Advances that were to have been converted on the first day of such Interest Period to Eurodollar Advances shall be continued as Floating Rate Advances and (z) any outstanding Eurodollar
Advances shall be converted, on the last day of the then-current Interest Period, to Floating Rate Advances. Until such notice has been withdrawn by the Agent, no further Eurodollar Advances shall be made or continued as such, nor shall any Borrower
have the right to convert Floating Rate Advances to Eurodollar Advances. 
 3.4. Funding Indemnification. If any payment
of a Eurodollar Advance or a Fixed Rate Loan occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made or continued, a Fixed Rate Loan
is not made or a Floating Rate Advance is not converted into a Eurodollar Advance on the date specified by the applicable Borrower for any reason other than default by the Lenders, a Eurodollar Advance or Fixed Rate Loan is not prepaid on the date
specified by such Borrower for any reason, or a Eurodollar Advance is prepaid by such Borrower without such Borrower providing at least three (3) Business Days’ prior notice to the Agent for any reason, such Borrower will severally, and
not jointly with the other Borrower, indemnify each Lender for any loss or cost incurred by such Lender resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance or
Fixed Rate Loan as determined by such Lender (if and to the extent such Lender, in its sole discretion, elects to impose such a charge). Such loss or cost to any Lender in liquidating or employing deposits acquired to fund or maintain any such
Eurodollar Advance or Fixed Rate Loan shall be an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the
Eurodollar Rate that would have been applicable to such Loan (but not including the Applicable Margin applicable thereto), for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by
placing such amount on deposit at the commencement of such period for a comparable period with leading banks in the London interbank eurodollar market. Notwithstanding the foregoing, a Defaulting Lender required to assign its Loans pursuant to
Section 2.22 shall not be entitled to compensation under this Section 3.4 in connection with any such assignment. 

3.5. Taxes. 
 (a) Any and all payments by or on account of any obligation of each Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If
any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled
to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant governmental authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by each Borrower
shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 3.5) the applicable Recipient receives an amount
equal to the sum it would have received had no such deduction or withholding been 

  
 50 

 
made. As soon as practicable after any payment of Taxes by either Borrower to a governmental authority pursuant to this Section 3.5, such Borrower shall deliver to the Agent the original or
a certified copy of a receipt issued by such governmental authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent. 

(b) The Borrowers shall timely pay to the relevant governmental authority in accordance with applicable law, or at the option of the
Agent timely reimburse it for, Other Taxes. 
 (c) The Borrowers shall jointly and severally indemnify each Recipient, within 20
days after written demand therefor (in each case setting forth the basis therefor and the manner of determination thereof), for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts
payable under this Section 3.5) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified
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 either Borrower by a Lender (with a copy to the Agent), or by the Agent on its own
behalf or on behalf of a Lender, shall be conclusive absent manifest error. 
 (d) Each Lender shall severally indemnify the
Agent, within 20 days after written demand therefor (in each case setting forth the basis therefor and the manner of determination thereof), for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrowers
have not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of the Borrowers to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.1(c)
relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising
therefrom or with respect thereto, whether or not such 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 any Lender, as applicable, by
the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to such Lender from any
other source against any amount due to the Agent under this Section 3.5(d) 
 (e) (i) Any Lender that is entitled to
an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the applicable Borrower and the Agent, at the time or times set forth herein or as are reasonably requested by such Borrower or
the Agent, such properly completed and executed documentation reasonably requested by such Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably
requested by the applicable Borrower or the Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by such Borrower or the Agent as will enable such Borrower or the Agent to determine whether or not such
Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation

  
 51 

 
(other than such documentation set forth in Sections 3.5(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or
submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. 
  

	 	(ii)	Without limiting the generality of the foregoing, in the event that either Borrower is a U.S. Person, 

(A) any Lender that is a U.S. Person shall deliver to such Borrower and the Agent on or prior to the date on which such
Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth herein or upon the reasonable request of the Borrower or the Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S.
federal backup withholding tax; 
 (B) any Non-U.S. Lender shall, to the extent it is legally entitled to do so,
deliver to such Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Non-U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth
herein or upon the reasonable request of such Borrower or the Agent), whichever of the following is applicable: 

(1) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party
(x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax
treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other
income” article of such tax treaty; 
 (2) executed originals of IRS Form W-8ECI; 

(3) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under
Section 881(c) of the Code, (x) a certificate to the effect that such Non-U.S. Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the
meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form
W-8BEN; or 
 (4) to the extent a Non-U.S. Lender is not the beneficial owner, executed originals of IRS Form
W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Non-U.S. Lender is a
partnership and one or more direct or indirect partners of such Non-U.S. Lender are claiming the portfolio interest exemption, such Non-U.S. Lender may provide a U.S. Tax Compliance Certificate on behalf of each such direct and indirect partner;

  
 52 

 (C) any Non-U.S. Lender shall, to the extent it is legally entitled to do
so, deliver to each Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth
herein or upon the reasonable request of either Borrower or the Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together
with such supplementary documentation as may be prescribed by applicable law to permit the Borrowers and the Agent to determine the withholding or deduction required to be made; and 

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by
FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to each Borrower and the Agent at
the time or times prescribed by law and at such time or times reasonably requested by either Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such
additional documentation reasonably requested by either Borrower or the Agent as may be necessary for Borrowers and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s
obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in
any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so. 
 (f) 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 this Section 3.5 (including by
the payment of additional amounts pursuant to this Section 3.5), 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 3.5 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 3.5(f) (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 3.5(f), in no event will the indemnified party be required to pay any amount to an
indemnifying party pursuant to this Section 3.5(f) 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 indemnification payments or additional
amounts giving rise to such refund had never been paid. This Section 3.5(f) shall not be 

  
 53 

 
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. 
 (g) Each party’s obligations under this Section 3.5 shall survive the resignation or replacement of the
Agent or any assignment of rights by, or the replacement of, a Lender and the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document. 

(h) For purposes of this Section 3.5, (i) the term “Lender” includes any applicable Lending Installation and any
Issuing Bank and (ii) the term “applicable law” includes FATCA. 
 3.6. Statements as to Claims; Survival of
Indemnity. The Agent, each Lender or each Issuing Bank, as the case may be, shall deliver a written statement to the applicable Borrower (with a copy to the Agent) as to each amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such
written statement shall set forth an explanation in reasonable detail of the manner in which such Lender determined such amount and shall be final, conclusive and binding on such Borrower in the absence of manifest error, and upon the reasonable
request of such Borrower, such Lender shall promptly provide supporting documentation describing and/or evidencing the applicable event giving rise to such amount to the extent not inconsistent with such Lender’s policies or applicable law.
Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type, currency and maturity corresponding to the
deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable within
fifteen (15) days (or, in the case of Section 3.5, twenty (20) days) after receipt by the applicable Borrower of such written statement, unless subject to a good faith dispute by such Borrower, notice and details of which were
provided to the affected Lender prior to such due date. The obligations of each Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement. Notwithstanding the foregoing, (a) the
Borrowers shall not be responsible for any reimbursement of any such amount under Section 3.1, 3.2, 3.4 or 3.5 which shall have accrued and of which the Agent or the applicable Lender or Issuing Bank, as the case may be, shall have become aware
more than 180 days prior to its delivery to the Borrower of notice requesting reimbursement thereof and (b) none of the Agent, any Lender or any Issuing Bank will make any claim (nor shall any Borrower have any liability) under
Section 3.1, 3.2 or 3.5 unless the Agent, such Lender or such Issuing Bank, as applicable, shall have determined that the making of such claim is consistent with its general practices under similar circumstances in respect of similarly situated
borrowers under credit agreements entitling it to make such claims. 
 3.7. Alternative Lending Installation. To the
extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrowers to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. A Lender’s designation of an alternative Lending Installation shall not affect the Borrowers’
rights under Section 2.22 to replace a Lender. 

  
 54 

 3.8. Allocation of Amounts Payable Among Borrowers. Each amount payable by “the
Borrowers” under this Article shall be an obligation of, and shall be discharged by (a) to the extent arising out of acts, events and circumstances related to a particular Borrower, such Borrower and (b) otherwise, both Borrowers,
with each Borrower being severally liable for such Borrower’s Contribution Percentage of such amount, provided that the Company agrees that, if the Borrowing Subsidiary shall fail to pay any amount owed by it under clause (b) of
this Section after a demand shall have been made by the Person to which such amount is owed, the Company shall promptly pay such amount (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of
the obligations of such Borrowing Subsidiary under this Section). 
 ARTICLE IV

 56 

 
following conditions are satisfied (it being acknowledged and agreed that conversions and continuations of Loans and Advances that do not result in an increase in the Aggregate Outstanding Credit

ARTICLE V 

REPRESENTATIONS AND WARRANTIES 
 Each Borrower severally, as to itself and, as applicable, its Subsidiaries, and not jointly with the other Borrower or its Subsidiaries, hereby represents and warrants to each Lender, each Issuing Bank
and the Agent: 
 5.1. Existence and Standing. Such Borrower and each of its Subsidiaries (other than any Project Finance
Subsidiary, Non-Material Subsidiary or SPC) is a corporation, partnership (in the case of Subsidiaries only) or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such
concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted, other than the
failure of any such Borrower or any of its Subsidiaries to so be in good standing or to be qualified to transact business in any such jurisdiction to the extent such failure could not reasonably be expected to result in a Material Adverse Effect
with respect to such Borrower. 

  
 57

Indebtedness of such Project Finance Subsidiary shall have occurred and be continuing.

 ARTICLE VIII 
 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES 
 8.1. Acceleration.
If any Default described in Section 7.6 or 7.7 occurs with respect to a Borrower, the obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder to such Borrower (and, if such Borrower is the
Borrowing 

  
 77 

 
Subsidiary, the Company) shall automatically terminate and the Obligations of such Borrower (and, if such Borrower is the Borrowing Subsidiary, the Company) shall immediately become due and
payable without any election or action on the part of the Agent, any Issuing Bank or any Lender. If any other Default occurs with respect to a Borrower, the Required Lenders (or the Agent at the direction of the Required Lenders) may terminate or
suspend the obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder to such Borrower, or declare the Obligations of such Borrower (and, in the case of a Default with respect to a Borrowing Subsidiary,
of the Company) to be due and payable, or both, whereupon the Obligations of such Borrower (and, in the case of a Default with respect to the Borrowing Subsidiary, of the Company) shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which such Borrower hereby expressly waives. 
 If, after acceleration of the
maturity of the Obligations or termination of the obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder as a result of any Default (other than any Default as described in Section 7.6 or 7.7 with
respect to such Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to such Borrower,
rescind and annul such acceleration and/or termination. 
 8.2. Amendments. None of this Agreement, any other Loan
Document or any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by each Borrower, the Agent and the Required Lenders and, in the
case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Agent and the other party or parties thereto, in each case with the consent of the Required Lenders; provided that (i) any provision
of this Agreement or any other Loan Document may be amended by an agreement in writing entered into by each Borrower and the Agent to correct any administrative or other manifest error, omission, defect or inconsistency so long as, in each case, the
Lenders shall have received at least seven Business Days’ prior written notice thereof and the Agent shall not have received, within seven Business Days of the date of such notice to the Lenders, a written notice from the Required Lenders
stating that the Required Lenders object to such amendment and (ii) no such agreement shall (A) increase the Commitment of any Lender without the written consent of such Lender, (B) reduce the principal amount of any Loan or LC
Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (C) except as expressly otherwise provided herein, postpone the scheduled maturity date of
any Loan or LC Disbursement or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent
of each Lender affected thereby, (D) change Section 11.2 in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender, (E) change any of the provisions of this Section or
the percentage set forth in the definition of the term “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any
determination or grant any consent thereunder, without the written consent of each Lender; provided that no such agreement shall amend, modify, extend or otherwise affect the rights or obligations of the Agent, any Issuing Bank or the
Swingline Lender without the prior written consent of the Agent, such Issuing Bank or the Swingline Lender, as the case may be. 

  
 78 

 Notwithstanding the foregoing, any provision of this Agreement may be amended by an
agreement in writing entered into by the applicable Borrower, the Required Lenders and the Agent if, by the terms of such agreement, (i) the Commitment of each Lender not consenting to the amendment provided for therein shall terminate upon the
effectiveness of such amendment and (ii) upon the effectiveness of such amendment, each Lender not consenting to such amendment shall receive payment in full of the principal of and interest accrued on each Advance made by it and all other
amounts owing to it or accrued for its account under this Agreement. 
 8.3. Preservation of Rights. No omission of the
Lenders, the Agent or the Issuing Banks to exercise or delay in exercising any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension
notwithstanding the existence of a Default or Unmatured Default or the inability of a Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such
right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by, or by the Agent with the consent of, the requisite number of Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Agent, the Issuing Banks and the Lenders until all of the Obligations have been paid in full. 
 ARTICLE IX 
 GENERAL PROVISIONS 

9.1. Survival of Representations. All representations and warranties of the Borrowers contained in this Agreement shall survive
the making of the Credit Extensions herein contemplated. 
 9.2. Governmental Regulation. Anything contained in this
Agreement to the contrary notwithstanding, no Lender shall be obligated to extend credit to either Borrower in violation of any limitation or prohibition provided by any applicable statute or regulation. 

9.3. Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the
interpretation of any of the provisions of the Loan Documents. 
 9.4. Entire Agreement. The Loan Documents embody the
entire agreement and understanding among the Agent, each Issuing Bank and the Lenders, and between the Agent, each Issuing Bank and the Lenders on one hand, and the Borrowers individually on the other hand, and supersede all prior agreements and
understandings among and between such parties, as the case may be, relating to the subject matter thereof (but do not supersede (a) any provisions of the fee letters related to the credit facilities established hereby or (b) the
indemnification and reimbursement provisions of any commitment letter related to the credit facilities established hereby to the extent applicable to the Arrangers and the Initial Lenders (as such terms are defined 

  
 79 

 
therein) in their capacities as such, that in each case do not by the terms of such documents terminate upon the effectiveness of this Agreement, all of which provisions shall remain in full
force and effect). 
 9.5. Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders and
the Issuing Banks hereunder are several and not joint and no Lender or Issuing Bank shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of the Agent, any Lender or any
Issuing Bank to perform any of its obligations hereunder shall not relieve the Agent, any other Lender or any Issuing Bank of any of its obligations hereunder. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.1(c)), and, with
respect to Sections 9.6, 9.10 and 10.11, the Arrangers, the Syndication Agents, the Documentation Agents and the Related Parties of any of the Agent, any Arranger, any Syndication Agent, any Documentation Agent, any Issuing Bank and any Lender) any

out-of-pocket expenses (including reasonable attorneys’ and paralegals’ fees and time charges of one outside legal counsel for the Agent and the Arrangers, and reasonable out-of-pocket expenses of and reasonable fees for other advisors and
professionals engaged by the Agent or any Arranger) paid or incurred by the Agent or the Arrangers in connection with the investigation, preparation, negotiation, documentation, execution, delivery, syndication, distribution (including via the

the Swingline Lender or any Lender in connection with the collection of the Obligations and enforcement of the Loan Documents. 

  

	 	(ii)	 Subject to paragraph (iii) below, the Borrowers hereby further agree to indemnify the Agent, each Arranger, each Issuing Bank, the Swingline
Lender, each Lender and their Related Parties against all losses, claims, damages, penalties, judgments, liabilities and expenses (including all expenses or liabilities related to or resulting from litigation or preparation therefor, whether
commenced by the Borrowers or their Affiliates or by any third party and whether or not the Agent, any Arranger, 

  
 80 

	 	
any Issuing Bank, the Swingline Lender, any Lender or any Affiliate is a party thereto, and all attorneys’ and paralegals’ fees, time charges and expenses of attorneys and paralegals of
the party seeking indemnification, which attorneys and paralegals may or may not be employees of such party seeking indemnification) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the
transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Loan hereunder, except to the extent that they have resulted, as determined in a final non-appealable judgment by a court of
competent jurisdiction, (a) from the gross negligence or willful misconduct of the party seeking indemnification or (b) from the material breach by the party seeking indemnification of its agreements hereunder or under the other Loan
Documents (it being agreed, however, that no such breach shall be deemed to occur as a result of any reasonable assertion in good faith by any indemnified party that any condition to any of its obligations hereunder has not been satisfied).

  

	 	(iii)	Each amount payable under paragraph (i) or (ii) of this Section shall be an obligation of, and shall be discharged by (a) to the extent arising out of
acts, events and circumstances related to a particular Borrower, such Borrower, and (b) otherwise, both Borrowers, with each of them being severally, but not jointly, liable for its Contribution Percentage of such amount; provided that
the Company agrees that, if the Borrowing Subsidiary shall fail to pay any amount owed by it under clause (b) of this paragraph (iii) after a demand shall have been made by the Person to which such amount is owed, the Company shall
promptly pay such amount (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of the Borrowing Subsidiary under this Section). 

 

	 	(iv)	To the extent that the Borrowers fail to pay any amount required to be paid by them to the Agent, any Arranger, the Swingline Lender or any Issuing Bank under paragraph
(i) or (ii) of this Section, each Lender severally agrees to pay to the Agent, the Arrangers, the Swingline Lender or such Issuing Bank, as the case may be, such Lender’s Pro Rata Share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the
Agent, the Arrangers, the Swingline Lender or such Issuing Bank in its capacity as such. 

  

	 	(v)	The obligations of the Borrowers under this Section 9.6 shall survive the termination of this Agreement and, as to each Borrower, the Availability Termination Date
of such Borrower. 

 9.7. Numbers of Documents. All statements, notices, closing documents, and requests
hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders, to the extent that the Agent deems necessary. 

  
 81 

 9.8. Accounting. Except as provided to the contrary herein, all accounting terms used
in the calculation of any financial covenant or test shall be interpreted and all accounting determinations hereunder in the calculation of any financial covenant or test shall be made in accordance with Agreement Accounting Principles. If any
changes in generally accepted accounting principles are hereafter required or permitted and are adopted by any Borrower or any of its Subsidiaries with the agreement of its independent certified public accountants and such changes result in a change
in the method of calculation of any of the financial covenants, tests, restrictions or standards herein or in the related definitions or terms used therein (“Accounting Changes”), the parties hereto agree, at the request of such Borrower,
the Agent or the Required Lenders, to enter into negotiations, in good faith, in order to amend such provisions in a credit neutral manner so as to reflect equitably such changes with the desired result that the criteria for evaluating such
Borrower’s and its Subsidiaries’ financial condition shall be the same after such changes as if such changes had not been made; provided, however, until such provisions are amended in a manner reasonably satisfactory to the
Company, the Agent and the Required Lenders, no Accounting Change shall be given effect in such calculations. In the event such amendment is entered into, all references in this Agreement to Agreement Accounting Principles shall mean generally
accepted accounting principles as of the date of such amendment. Notwithstanding the foregoing, all financial statements to be delivered by such Borrower pursuant to Section 6.1 shall be prepared in accordance with generally accepted accounting
principles in effect at such time (subject in the case of interim financial statements, to the absence of footnotes and year-end adjustments). Notwithstanding the foregoing, for purposes of all accounting or financial calculations made under this
Agreement and for purposes of defining and calculating Indebtedness hereunder, leases that would have been classified as operating leases in accordance with Agreement Accounting Principles as in effect on June 30, 2010, whether entered into
before or after the Closing Date, will be treated in a manner consistent with the treatment of such leases under Agreement Accounting Principles as in effect on June 30, 2010, notwithstanding any modifications or interpretive changes in
Agreement Accounting Principles that may occur thereafter. 
 9.9. Severability of Provisions. Any provision in any Loan
Document that is held to be inoperative, unenforceable or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable or invalid without affecting the remaining provisions in that jurisdiction or the operation,
enforceability or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable. 
 9.10. Nonliability. The relationship between the Borrowers individually on the one hand and the Lenders, each Issuing Bank and the Agent on the other hand shall be solely that of borrower and
lender. No provision in any Loan Document, the transactions contemplated thereby, any relationships established thereby, any communications pursuant thereto or the nature of services provided by the Lenders, each Issuing Bank and the Agent shall
create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lenders, each Issuing Bank and the Agent on the one hand and the Borrowers and their subsidiaries, Affiliates or equityholders on the other hand.
None of the Agent, any Arranger, any Issuing Bank or any Lender undertakes any responsibility to the Borrowers to review or inform the Borrowers of any matter in connection with any phase of the Borrowers’ businesses or operations. The
Borrowers agree that none of the Agent, any Arranger, any Issuing Bank or any Lender shall have liability to the Borrowers (whether sounding in tort, contract or otherwise) for 

  
 82 

 
losses suffered by the Borrowers in connection with, arising out of or in any way related to the transactions contemplated and the relationship established by the Loan Documents or any act,
omission or event occurring in connection therewith unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from (a) the gross negligence or willful misconduct of the party from
which recovery is sought or (b) the material breach by the party from which recovery is sought of its agreements hereunder or under the other Loan Documents (it being agreed, however, that no such breach shall be deemed to occur as a result of
any reasonable assertion in good faith by the Agent, any Arranger, any Issuing Bank or any Lender that any condition to any of its obligations hereunder has not been satisfied). None of the Borrowers, the Agent, any Arranger, any Issuing Bank or any
Lender shall have any liability for, and each of the Agent, each Arranger, each Issuing Bank, each Lender and each Borrower hereby waives, releases and agrees not to sue for, any special, indirect, consequential or punitive damages in connection
with, arising out of or in any way related to the Loan Documents or the transactions contemplated thereby; provided, that each Borrower shall be obligated as, and subject to the limitations, provided in Section 9.6 to indemnify the
Agent, each Arranger, each Issuing Bank, the Swingline Lender, each Lender and their Related Parties against any special, indirect, consequential or punitive damages that may be awarded against them. 

9.11. Confidentiality. Each Lender and each Issuing Bank agrees to hold any confidential information which it may receive from
either Borrower pursuant to this Agreement in confidence, except for disclosure (i) to its Affiliates and to other Borrowers, Lenders or Issuing Banks and their respective Affiliates, for use solely in connection with the transactions
contemplated hereby, (ii) to legal counsel, accountants, and other professional advisors to, and agents, officers and employees of, such Lender or Issuing Bank, in each case which have been informed as to the confidential nature of such
information, for use solely in connection with the transactions contemplated hereby, (iii) to regulatory officials having jurisdiction over it or its Affiliates, (iv) to any Person as required by law, regulation, or legal process
(provided that, to the extent legally permitted, such Lender or Issuing Bank shall provide each Borrower with notice of such required disclosure to permit the Borrowers to contest the necessity thereof), (v) to any Person in connection
with any legal proceeding arising under or in connection with this Agreement, the Loan Documents or the transactions contemplated hereby to which such Lender or Issuing Bank is a party (provided that, to the extent legally permitted, such
Lender or Issuing Bank shall provide the Borrowers with notice of such required disclosure to permit the Borrowers to contest the necessity thereof), (vi) to any assignee of or participant in, or prospective assignee of or participant in, any
of its rights or obligations under this Agreement, if and to the extent such Person has been informed as to the confidential nature of such information and has agreed to treat such information in accordance with the terms of this Section 9.11,
(vii) to such Lender’s or Issuing Bank’s direct or indirect contractual counterparties in swap agreements or credit insurance providers with respect to the credit facilities established hereunder, or to legal counsel, accountants and
other professional advisors to any of the foregoing, in each case which have been informed as to the confidential nature of such information and have agreed to treat such information in accordance with the terms of this Section 9.11,
(viii) to rating agencies if requested or required by such agencies in connection with a rating relating to this Agreement or the Advances hereunder, (ix) with the consent of such Borrower, (x) to any other party to this Agreement,
(xi) in connection with the exercise of any remedies under this Agreement or any other Loan Document or any suit, action or proceeding 

  
 83 

 
relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder and (xii) the CUSIP Service Bureau or any similar agency in connection with the
issuance and monitoring of CUSIP numbers with respect to the credit facilities established hereunder. 
 9.12. Lenders Not
Utilizing Plan Assets. Each Lender represents and warrants that none of the consideration used by such Lender to make its Loans constitutes for any purpose of ERISA or Section 4975 of the Code assets of any “plan” as defined in
Section 3(3) of ERISA or Section 4975 of the Code and the rights and interests of such Lender in and under the Loan Documents shall not constitute such “plan assets” under ERISA. 

9.13. Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in
Regulation U) as collateral in the extension or maintenance of the credit provided for herein. 
 9.14. Disclosure. Each
Borrower, Lender and Issuing Bank hereby acknowledges and agrees that each Lender, each Issuing Bank and their Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrowers and their
Affiliates. 
 9.15. USA Patriot Act. Each Lender and each Issuing Bank hereby notifies the Borrowers that pursuant to
the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the names and addresses of the Borrowers and other information that will allow such Lender to
identify the Borrowers in accordance with its requirements. The Borrowers shall, promptly following a request by the Agent or any Lender, provide all documentation and other information that the Agent or such Lender reasonably requests in order to
comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations including the USA Patriot Act. 
 9.16. Non-Public Information. Each Lender acknowledges that all information, including requests for waivers and amendments, furnished by the Borrowers or the Agent pursuant to or in connection
with, or in the course of administering, this Agreement will be syndicate-level information, which may contain MNPI. Each Lender represents to the Borrowers and the Agent that (i) it has developed compliance procedures regarding the use of MNPI
and that it will handle MNPI in accordance with such procedures and applicable law, including Federal, state and foreign securities laws, and (ii) it has identified in its Administrative Questionnaire a credit contact who may receive
information that may contain MNPI in accordance with its compliance procedures and applicable law, including Federal, state and foreign securities laws. 
 ARTICLE X 
 THE AGENT 

10.1. Appointment; Nature of Relationship. JPMCB is hereby appointed by each of the Lenders and each of the Issuing Banks as its
contractual representative (herein referred to as the 

  
 84 

 
“Agent”) hereunder and under each other Loan Document, and each of the Lenders and the each of the Issuing Banks irrevocably authorizes the Agent to act as the contractual
representative of such Lender and such Issuing Bank with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this
Article X. Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender or any Issuing Bank by reason of this Agreement or any other
Loan Document and that the Agent is merely acting as the contractual representative of the Lenders and the Issuing Banks with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the
Lenders’ and the Issuing Banks’ contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders or the Issuing Banks, (ii) is a “representative” of the Lenders and the Issuing
Banks within the meaning of the term “secured party” as defined in the New York Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this
Agreement and the other Loan Documents. Each of the Lenders and the Issuing Banks hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender
hereby waives. 
 10.2. Powers. The Agent shall have and may exercise such powers under the Loan Documents as are
specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties or fiduciary duties to the Lenders or the Issuing Banks, or any obligation to
the Lenders or the Issuing Banks to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent. Without limiting any other power granted under any Loan Document, each Lender authorizes and
directs the Agent to vote all the interests of the Lenders as a single bloc based upon the direction of the Required Lenders as contemplated by any Loan Document. 
 10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrowers, the Lenders or any Lender or any Issuing Bank for any action
taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final, non-appealable judgment by a court of competent
jurisdiction to have arisen from (i) the gross negligence or willful misconduct of the party from which recovery is sought or (ii) the material breach by such party of its agreements hereunder or under the other Loan Documents (it being
agreed, however, that no such breach shall be deemed to occur as a result of any reasonable assertion in good faith by the Agent, any Arranger, any Issuing Bank or any Lender that any condition to any of its obligations hereunder has not been
satisfied). 
 10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers,
agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or
observance of any of the covenants or agreements of any obligor under any Loan Document, including any agreement by an obligor to furnish information directly to each Lender and each Issuing Bank; (c) the satisfaction of any condition specified
in Article IV, except receipt of items required to be 

  
 85 

 
delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness
of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrowers
or any guarantor of any of the Obligations or of any of the Borrowers’ or any such guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders or the Issuing Banks information that is not required to be
furnished by the Borrowers to the Agent at such time, but is voluntarily furnished by the Borrowers to the Agent (either in its capacity as Agent or in its individual capacity). 

10.5. Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly requires such), and such instructions and any
action taken or failure to act pursuant thereto shall be binding on all of the Lenders and each Issuing Bank. The Lenders and each Issuing Bank hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be
taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly
requires such). The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction in writing by the Lenders pro rata against any and all
liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 
 10.6. Employment
of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders or the Issuing Banks, except as
to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual
arrangement between the Agent and the Lenders and the Issuing Banks and all matters pertaining to the Agent’s duties hereunder and under any other Loan Document. 
 10.7. Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it in
good faith to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent. 

10.8. Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent, severally and not
jointly, ratably in proportion to the their Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Aggregate Outstanding Credit Exposure) (determined as of the date of any such request by the Agent)
(i) for any amounts not reimbursed by the Borrowers for which the Agent is entitled to reimbursement by the Borrowers under the Loan Documents in its capacity as Agent, (ii) to the extent not paid by the Borrowers, for any other expenses
incurred by the Agent on behalf of the Lenders or the Issuing Banks, in connection with the preparation, execution, delivery, 

  
 86 

 
administration and enforcement of the Loan Documents (including for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of
the Lenders or Issuing Banks) and (iii) to the extent not paid by the Borrowers, for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which
may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including for any such amounts
incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders or Issuing Banks), or the enforcement of any of the terms of the Loan Documents or of any such other
documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of the Agent, (ii) any indemnification required pursuant to Section 3.5(d) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions
thereof and (iii) the Agent shall reimburse the Lenders for any amounts the Lenders have paid to the extent such amounts are subsequently recovered from the Borrowers. The obligations of the Lenders under this Section 10.8 shall survive
payment of the Obligations, termination and expiration of the Letters of Credit and termination of this Agreement. 
 10.9.
Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or a Borrower referring to this Agreement
describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Borrowers, the Lenders and the
Issuing Banks. 
 10.10. Rights as a Lender. In the event the Agent is a Lender or an Issuing Bank, the Agent shall have
the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Credit Extensions as any Lender or any Issuing Bank and may exercise the same as though it were not the Agent, and the term
“Lender” or “Lenders” or “Issuing Bank” shall, at any time when the Agent is a Lender or an Issuing Bank, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with each Borrower or any of its
Subsidiaries in which such Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender. 

10.11. Independent Credit Decision. Each Lender and each Issuing Bank acknowledges that it has, independently and without reliance
upon the Agent, any Arranger or any other Lender or any other Issuing Bank and based on the financial statements prepared by the Borrowers and such other documents and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Loan Documents. Each Lender and each Issuing Bank also acknowledges that it will, independently and without reliance upon the Agent, any Arranger or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents. 

  
 87 

 10.12. Successor Agent. The Agent may resign at any time by giving written notice
thereof to the Lenders, the Issuing Banks and the Borrowers, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. Upon any such resignation, the Required Lenders, with the consent of the Borrowers (which consent shall not be unreasonably withheld or delayed; provided that such consent shall not be required in the event and
continuation of a Default), shall have the right to appoint, on behalf of the Borrowers and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders or consented to by the Borrowers within thirty
days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrowers and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time
without the consent of the Borrowers or any Lender or any Issuing Bank, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned and no successor Agent has been appointed, the Required
Lenders may perform all the duties of the Agent hereunder and the Borrowers shall make all payments in respect of the Obligations to the applicable Lenders and for all other purposes shall deal directly with the Lenders. If the Agent has resigned
and, at such time, holds cash collateral under this Agreement, the Agent shall continue to hold such cash collateral for the benefit of the Lenders and the applicable Issuing Bank until a successor Agent has been appointed. No successor Agent shall
be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Unless otherwise agreed by the Company, any such successor Agent shall be a Lender or, if no Lender will accept such appointment, a commercial bank having
capital and retained earnings of at least $1,000,000,000 (or such lower amount as shall be acceptable to the Company). Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the resigning Agent. Upon the effectiveness of the resignation of the Agent, the resigning Agent shall be discharged from its duties and obligations hereunder and under the Loan
Documents. After the effectiveness of the resignation of the Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent
hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as
used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent. 
 10.13. Agent and
Arrangers Fees. Each Borrower severally and not jointly agrees to pay to the Agent and each Arranger, for their respective accounts, the agent and arrangers fees separately agreed to by such Borrowers, the Agent and such Arranger pursuant to and
in accordance with those certain fee letters dated as of September 21, 2012 and as otherwise mutually agreed to in writing from time to time. 
 10.14. Delegation to Affiliates. The Borrowers, the Lenders and the Issuing Banks agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates (it being agreed
that the Agent will remain responsible for the performance of all such duties). Any 

  
 88 

 
such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X. 
 10.15.
Joint Arrangers, Joint Bookrunners, Syndication Agents and Documentation Agents. The Persons identified in this Agreement as “Joint Arrangers”, “Joint Bookrunners”, “Syndication Agents” and “Documentation
Agents”, in such capacities, shall have no right, power, obligation, liability, responsibility or duty under this Agreement. Without limiting the foregoing, such Persons, in such capacities, shall not have or be deemed to have a fiduciary
relationship with any other Person. Each Lender hereby makes the same acknowledgements with respect to such Persons as it makes with respect to the Agent in Section 10.11. 
 ARTICLE XI 
 SETOFF; RATABLE PAYMENTS 

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Borrower becomes
insolvent or any payment Default pursuant to Section 7.2 occurs with respect to a Borrower, or any other Default with respect to a Borrower shall occur and be continuing and the Required Lenders shall have terminated any Commitments as to such
Borrower or accelerated the maturity of any Loans to such Borrower, then any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or
owing by any Lender or any Affiliate of any Lender or any Issuing Bank to or for the credit or account of such Borrower may be offset and applied toward the payment of the Obligations owing by such Borrower to such Lender or such Issuing Bank,
whether or not the Obligations, or any part thereof, shall then be due. Promptly upon the exercise of its right of setoff hereunder, each Lender and Issuing Bank shall deliver written notice thereof to the Agent and the Agent shall make such notice
available to the other Lenders and Issuing Banks. 
 11.2. Ratable Payments. If any Lender shall, by exercising any right
of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at
face value) participations in the Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the amount of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amounts of principal of and accrued interest on their Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by
the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or 

  
 89 

 
participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to either Borrower, any other Subsidiary or any Affiliate of any of the foregoing (as to which the
provisions of this paragraph shall apply). Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise
against each Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), except that (i) no Borrower may assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of the Agent and each Lender (and any attempted assignment or transfer by either Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or

(including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: 

(A) each Borrower; provided that no consent of the Borrowers shall be required (1) for an assignment to a
Lender, an Affiliate of a Lender or an Approved Fund and (2) if a Default has occurred and is continuing, for any other assignment; provided further, that each Borrower will be deemed to have consented to an assignment if it does not
respond to a written request for a consent thereto within 10 Business Days after actual receipt of such request; 
 (B) the Agent; provided that no consent of the Agent shall be required for an assignment to a Lender or an Affiliate of a Lender; 

(C) each Issuing Bank; and 
 (D) the Swingline Lender. 

  
 90 

	 	(ii)	Assignments shall be subject to the following additional conditions: 

(A) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the
entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Agent) shall not be less than $5,000,000 unless each Borrower and the Agent otherwise consent; provided that no such consent of the Borrowers shall be required if a Default has occurred and is continuing;

 (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning
Lender’s rights and obligations under this Agreement, except that this sentence shall not apply to rights in respect of outstanding Competitive Loans; 
 (C) the parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 

(D) the assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire in which the
assignee designates one or more credit contacts to whom all syndicate-level information (which may contain MNPI) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable
law, including Federal, State and foreign securities laws. 
  

	 	(iii)	Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and
Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all the assigning Lender’s rights and obligations under this
Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Article III and Section 9.6). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply
with this Section 12.1 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such Lender’s rights or obligations as provided in Section 12.1(c). 

 

	 	(iv)	 The Agent shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and records of the names and addresses of the
Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent

  
 91 

	 	
manifest error and the Borrowers, the Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by either Borrower and, as to entries pertaining to it, any Issuing Bank or Lender, at any reasonable time and from time to time
upon reasonable prior notice. 

  

	 	(v)	Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative
Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in this Section and any written consent to such assignment required by this Section, the Agent shall accept such Assignment
and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. Each assignee, by its execution
and delivery of an Assignment and Assumption, shall be deemed to have represented to the assigning Lender and the Agent that such assignee is an Eligible Assignee. 

(c) Participations. 
  

	 	(i)	Any Lender may, without the consent of either Borrower, the Agent, any Issuing Bank or the Swingline Lender, sell participations to one or more Eligible Assignees
(“Participants”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s
obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Agent, the Issuing Banks, the Swingline
Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement or any other Loan
Document; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.2 that affects
such Participant or requires the approval of all of the Lenders. Subject to paragraph (c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Article III to the same extent as if it were a Lender
and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided such
Participant agrees to be subject to Section 11.2 as though it were a Lender. 

  
 92 

	 	(ii)	A Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the applicable Lender would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Non-U.S. Lender if it were a Lender shall not
be entitled to the benefits of Section 3.5 unless each Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.5 as though it were a Lender.

  

	 	(iii)	Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name
and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under any Loan Document (the “Participant Register”); provided that no
Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its
other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the
United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for
all purposes of any Loan Document notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent shall have no responsibility for maintaining a Participant Register. 

(d) Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this
Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that
no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

 DISCLOSED MATTERS 
 (See Section 1.1) 

Pending Electric Rate Case 
 In February 2012, Union Electric Company (“Ameren Missouri”) filed a request with the Missouri Public Service Commission (“MoPSC”) to increase its annual revenue for
electric service. The currently pending request, as amended in October 2012, seeks an annual revenue increase of $323 million based on a 10.5% return on equity. The annual increase request includes $73 million related to an anticipated increase in
normalized net fuel costs above the net fuel costs included in base rates previously authorized by the MoPSC in its 2011 electric rate order. The annual increase request also includes $80 million for recovery of the costs associated with energy
efficiency programs under the Missouri Energy Efficiency Investment Act (“MEEIA”), which are discussed below. In this rate case, Ameren Missouri requested that the MoPSC approve the implementation of a storm cost tracking mechanism,
as well as plant-in-service accounting treatment. The plant-in-service accounting proposal is designed to reduce the impact of regulatory lag on earnings and future cash flows related to assets placed in service between rate cases by both accruing a
return on the assets and deferring depreciation expense from their in-service dates until those capitalized costs are included in rates. 
 The MoPSC staff is currently recommending an increase to Ameren Missouri’s annual revenues of $210 million based on a return on equity of 9%. The MoPSC staff opposed Ameren Missouri’s request to
implement a storm cost tracking mechanism and Ameren Missouri’s plant-in-service accounting proposal. The MoPSC staff also recommended that all transmission costs currently recovered through the FAC (as defined below) be recovered through base
rates. Other parties also made recommendations through testimony filed in this case. 
 Ameren Missouri has agreed to
settlements of various issues, some of which have been approved by the MoPSC and some of which are still subject to approval by the MoPSC. One of the approved settlements will allow Ameren Missouri to retain the refund received in June 2012 from
Entergy Arkansas, Inc. (“Entergy”) related to a power purchase agreement that existed prior to the implementation of the FAC, which did not impact Ameren Missouri’s pending request. 

The MoPSC has several important issues to consider in this case. Those issues include determining the appropriate return on equity,
Ameren Missouri’s request for the implementation of a storm cost tracking mechanism and plant-in-service accounting treatment, Ameren Missouri’s request for recovery of its 2011 severance costs, and whether Ameren Missouri should be able
to continue to employ its existing FAC, including all of the transmission costs currently included within the FAC, at the current 95% sharing level. 
 A decision by the MoPSC in this proceeding is expected in December 2012, with rates becoming effective on January 2, 2013. Ameren Missouri cannot predict the level of any electric service rate change
the MoPSC may approve or whether any rate increase that may eventually be approved will be sufficient for Ameren Missouri to recover its costs and earn a reasonable return on its investments when the increase goes into effect. 

  
 Schedule 6
Page 1 

 As used in this Schedule 6 “FAC” means a fuel and purchased power cost recovery
mechanism that allows Ameren Missouri to recover, through customer rates, 95% of changes in fuel (coal, coal transportation, natural gas for generation, and nuclear), emission allowances and purchased power costs, net of off-system revenues,
including MISO (Midwest Independent Transmission System Operator, Inc., a Regional Transmission Organization) costs and revenues, greater or less than the amount set in base rates, without a traditional rate proceeding. 

MEEIA Filing 
 In August 2012, the MoPSC issued an order that approved a stipulation and agreement between Ameren Missouri, MoPSC staff, and other parties. The order includes megawatthour savings targets for Ameren
Missouri's energy efficiency programs as well as associated cost recovery mechanisms and incentive awards. The order provides that, beginning in 2013, Ameren Missouri will invest approximately $147 million over three years for energy efficiency
programs. The order allows for Ameren Missouri to collect, over the next three years, its program costs and 90% of its projected lost revenue from customers starting on the expected effective date for the pending electric service rate case, which is
expected to be January 2, 2013. The remaining 10% of projected lost revenue is expected to be recovered as part of future rate proceedings. 
 Additionally, the order provides for an incentive award that would allow Ameren Missouri to earn additional revenues based on achievement of certain energy efficiency goals, including approximately $19
million if 100% of its energy efficiency goals are achieved during the three-year period, with the potential to earn more if Ameren Missouri’s energy savings exceed those goals. Ameren Missouri must achieve at least 70% of its energy efficiency
goals before it earns any incentive award. The recovery of the incentive award from customers, if the energy efficiency goals are achieved, would begin after the three-year energy efficiency plan is complete and upon the effective date of an
electric service rate case or potentially with the future adoption of a rider mechanism. 
 The MoPSC’s order will not
affect Ameren Missouri rates until these rates are included in an electric service rate case. The impacts of the MoPSC’s order in this MEEIA filing are expected to be included in rates set under Ameren Missouri’s pending electric service
rate case that was filed in February 2012. Ameren Missouri’s pending electric service rate case includes an annual revenue increase request of $80 million related to its planned portfolio of energy efficiency programs included in its MEEIA
filing.

 EXHIBIT A 
 November 14, 2012 
 To the Lenders and 

JPMorgan Chase Bank, N.A., as Agent 
 383 Madison
Avenue 
 New York, NY 10179 
 Dear
Ladies and Gentlemen: 
 I, Gregory L. Nelson, am the Senior Vice President, General Counsel and Secretary of Ameren Corporation,
a Missouri corporation (the “Company”), and its subsidiary Union Electric Company, d/b/a Ameren Missouri, a Missouri corporation (“UE” and together with the Company, the “Borrowers” and each a
“Borrower”). I, or lawyers under my direction, have acted as counsel for each of the Borrowers in connection with the Credit Agreement dated as of November 14, 2012 (the “Credit Agreement”), among the
Borrowers, the lenders from time to time party thereto (the “Lenders”) and JPMorgan Chase Bank, N.A., as Agent. Capitalized terms used and not otherwise defined herein have the meanings assigned to such terms in the Credit
Agreement. 
 In rendering the opinion expressed below, I, or lawyers under my direction, have examined originals or copies,
certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or advisable
for purposes of this opinion. 
 In making the examinations described above, I have assumed without independent investigation
the capacity of natural persons (other than the office held by each representative of the Borrowers) as reflected adjacent to such individual’s signature on the Credit Agreement and the Notes (each a “Loan Document” and
collectively, the “Loan Documents”), the genuineness of all signatures (other than those of representatives of the Borrowers appearing on the Loan Documents), the authenticity of all documents furnished to me as originals, the
conformity to originals of all documents furnished to me as certified or photostatic copies and the authenticity of the originals of such documents. In addition, I have assumed without independent investigation that (i) the Loan Documents have
been duly authorized, executed and delivered by the Lenders and the Agent, and constitute their valid, lawful and binding obligation and agreement, and (ii) there is no separate agreement, undertaking, or course of dealing modifying, varying or
waiving any of the terms of the Loan Documents. As to matters of fact not independently established by me relevant to the opinions set forth herein, I have relied without independent investigation on the representations contained in the Loan
Documents and in certificates of public officials and responsible representatives of each Borrower furnished to me; provided, however, that I advise that in the course of my representation of the Borrowers, I obtained no information
that leads me to believe that any such representation or certificate is untrue or misleading in any material respect. 

 Upon the basis of and subject to the foregoing, I am of the opinion that: 

1. Each of the Borrowers is a corporation, duly and properly incorporated, validly existing and in good standing under the laws of the
State of Missouri and has all requisite authority to conduct its business as presently conducted in each jurisdiction in which its business is conducted, other than the failure of any such Borrower to be qualified to transact business in any such
jurisdiction to the extent such failure could not reasonably be expected to result in a Material Adverse Effect. 
 2. Each of
the Borrowers has the power and authority and legal right to execute and deliver, and to perform its obligations under, the Loan Documents. The execution and delivery by each of the Borrowers of the Loan Documents, and the performance by each of the
Borrowers of its obligations under the Loan Documents, have been duly authorized by proper proceedings, and the Loan Documents to which such Borrower is a party constitute legal, valid and binding obligations of such Borrower enforceable against
such Borrower in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights
generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing. 

3. Neither the execution and delivery by the Borrowers of the Loan Documents, nor the consummation of the transactions contemplated
therein, nor the performance by the Borrowers of the obligations thereunder, (x) violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on such Borrower or (ii) such Borrower’s articles
or certificate of incorporation or by-laws, or (iii) the provisions of any indenture, any material instrument or any material agreement to which such Borrower is a party or is subject, or by which it, or its Property, is bound, or
(y) conflict with, or constitute a default under, or result in, or require, the creation or imposition of any Lien in, of or on the Property of such Borrower pursuant to the terms of, any such indenture, instrument or agreement. No order,
consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has
not been obtained by such Borrower, is required to be obtained by such Borrower in connection with the execution and delivery of the Loan Documents, the borrowings and issuances of Letters of Credit for account of such Borrower under the Loan
Documents, the payment and performance by such Borrower of its Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents with respect to such Borrower. 

4. Except for the Disclosed Matters, there is no litigation, arbitration, governmental investigation, proceeding or inquiry currently
existing, or, to the best of my knowledge after due inquiry, pending or threatened against or affecting the Borrowers or any of their Subsidiaries, which, if determined adversely to such Borrower or any of its Subsidiaries, could reasonably be
expected to have a Material Adverse Effect with respect to such Borrower or any of its Subsidiaries or which seeks to prevent, enjoin or delay the making of any Loans or would adversely effect the legality, validity or enforceability of the Loan
Documents as to such Borrower or the ability of such Borrower to perform the transactions contemplated therein. 
 5. No Borrower
is an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended. 

  
 - 2 -

 6. The Company is a “holding company” and UE is a “public utility,” as
such terms are defined in the Public Utility Holding Company Act of 2005. The FERC, in accordance with Section 204 of the Federal Power Act, has issued a FERC Order dated April 9, 2012, with respect to UE, which is in full force and
effect, authorizing the incurrence of short-term indebtedness by UE in an aggregate principal amount outstanding not to exceed $1 billion. The authorization under the April 9, 2012 FERC Order expires March 31, 2014. Unless such
authorization is no longer required by applicable laws and regulations, additional authorization from the FERC (or any governmental agency that succeeds to the authority of the FERC) or the Missouri Public Service Commission will be necessary for UE
to obtain any Advances under the Credit Agreement or to incur or issue short-term indebtedness, including Advances extended under the Credit Agreement, after March 31, 2014. No regulatory authorizations, approvals, consents, registrations,
declarations or filings are required in connection with the borrowings by, and issuances of Letters of Credit for the account of, the Borrowers under the Credit Agreement or the performance by each Borrower of its Obligations under the Credit
Agreement and under the other Loan Documents, except as set forth above or where the failure to have obtained, made or maintained any such authorizations, approvals, consents, registrations, declarations or filings could not reasonably be expected
to result in a Material Adverse Effect with respect to such Borrower. 
 7. In a properly presented case, a Missouri court or a
federal court applying Missouri choice of law rules should give effect to the choice of law provisions of the Loan Documents and should hold that the Loan Documents are to be governed by the laws of the State of New York rather than the laws of the
State of Missouri. In rendering the foregoing opinion, I note that by their terms the Loan Documents expressly select New York law as the law governing their interpretation. The choice of law provisions of the Loan Documents are not voidable
under the laws of the State of Missouri. Notwithstanding the foregoing, even if a Missouri court or a federal court holds that the Loan Documents are to be governed by the laws of the State of Missouri, the Loan Documents would constitute
legal, valid and binding obligations of each of the Borrowers, enforceable under Missouri law (including usury provisions) against such Borrower in accordance with their terms, except as enforceability may be limited by (i) bankruptcy,
insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and
(iii) requirements of reasonableness, good faith and fair dealing. 
 I express no opinion as to the compliance or
noncompliance, or the effect of the compliance or noncompliance, of any addressee with any state or federal laws or regulations applicable to it by reason of its status as or affiliation with a federally insured depository institution. 

I am a member of the Bar of the State of Missouri and the foregoing opinion is limited to the laws of the State of Missouri and the
Federal laws of the United States of America. I note that the Loan Documents are governed by the laws of the State of New York and, for purposes of the opinion expressed in opinion paragraph 2 above and with your permission, I have assumed that the
laws of the State of New York do not differ from the laws of the State of Missouri in any manner that would render such opinion incorrect. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied
upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without my prior written 

  
 - 3 -

 
consent. Notwithstanding anything in this opinion letter to the contrary, you may disclose this opinion (i) to prospective successors and assigns of the addressees hereof, (ii) to
regulatory authorities having jurisdiction over any of the addressees hereof or their successors and assigns, and (iii) pursuant to valid legal process, in each case without my prior consent.

 This opinion is delivered as of the date hereof and I undertake no, and disclaim any,
obligation to advise you of any change in matters of law or fact set forth herein or upon which this opinion is based.

 All subordinated indebtedness (hereinafter referred to as
“Subordinated Debt”) of any Borrower incurred after the date of this Agreement that is not being included in the calculation of Consolidated Indebtedness pursuant to subclause (i)(B)(x) of the proviso in Section 6.15 shall be
in the form of indebtedness of such Borrower to the Company or any of its Subsidiaries that is subordinate and junior to any and all indebtedness (hereinafter referred to as “Senior Debt”) of such Borrower, whether existing on the
date of this Agreement or thereafter incurred, in respect of (i) all Obligations of such Borrower under this Agreement, including Obligations in respect of Letters of Credit, (ii) other borrowings of such Borrower from any one or more
banks, insurance companies, pension or profit sharing trusts or other financial institutions whether secured or unsecured and (iii) all other borrowings incurred, assumed or guaranteed by such Borrower, at any time, evidenced by a note,
debenture, bond or other similar instrument (including capitalized lease and purchase money obligations, and/or for the acquisition (whether by way of purchase, merger or otherwise) of any business, real property or other assets (except assets
acquired in the ordinary course of business) but excluding obligations other than for borrowed money including trade payables and other obligations to general creditors) other than indebtedness which, by its terms or the terms of the instrument
creating or evidencing it, provides that such indebtedness is subordinated to all other indebtedness of such Borrower. Notwithstanding any other provision of this Agreement or this Exhibit F, “Senior Debt” shall include refinancings,
renewals, amendments, extensions or refundings of the indebtedness described in clauses (i) through (iii) above. 

“Subordinate and junior” as used herein shall mean that in the event of: 

(a) any default in, or violation of, the terms or covenants of any Senior Debt, including any default in payment of
principal of, or premium, if any, or interest on, any Senior Debt whenever due (whether by acceleration of maturity or otherwise), and during the continuance thereof, or 

(b) the institution of any liquidation, dissolution, bankruptcy, insolvency, reorganization or similar proceeding relating
to any Borrower, its property or its creditors as such, 
 the obligee of indebtedness so described shall not be entitled to receive any payment
of principal of, or premium, if any, or interest on, such indebtedness until all amounts owing in respect of Senior Debt (matured and unmatured) shall have been paid in full; and from and after the happening of any event described in clause
(b) of this paragraph, all payments and distributions of any kind or character (whether in cash, securities or property) which, except for the subordination provisions hereof, would have been payable or distributable to the obligee of such
indebtedness (whether directly or by reason of being superior to any other indebtedness), shall be made to and for the benefit of the holders of Senior Debt (who shall be entitled to make all necessary claims therefor) in accordance with the
priorities of payment thereof until all Senior Debt (matured and unmatured) shall have been paid in full. No act or failure to act on the part of any Borrower, and no default under or breach of any agreement of such Borrower, whether or not herein
set forth, shall in any way prevent or limit the holder of any Senior Debt from 

 
enforcing fully the subordination terms herein provided for, irrespective of any knowledge or notice which such holder may at any time have or be charged with. In the event that any payment or
distribution is made with respect to Subordinated Debt in violation of the terms of this Exhibit F or any outstanding Senior Debt, any holder of Subordinated Debt receiving such payment or distribution shall hold it in trust for the benefit of,

any Swingline Loan until and unless it shall be satisfied that the events and circumstances described in such notice shall have been cured or otherwise shall have ceased to exist). Each Lender further acknowledges and agrees that its obligation to
acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of any Default or Unmatured Default or any
reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of

Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the account party or account parties with respect to such Letter of Credit, the name and address of the beneficiary
thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit, together, in the case of a request for an issuance of a Letter of Credit, with draft language for such Letter of Credit reasonably
acceptable to the applicable Issuing Bank. If requested by the applicable Issuing Bank, such Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A
Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit, such Borrower shall be deemed to represent and warrant that), after giving effect to such issuance,
amendment, renewal or extension (i) the Aggregate Outstanding Credit Exposure will not exceed the Aggregate Commitment, (ii) the Revolving Credit Exposure of any Lender will not exceed its Commitment, (iii) the Borrower Credit
Exposure of the Borrower requesting such Letter of Credit will not exceed the Borrower Sublimit of such Borrower, (iv) the portion of the LC Exposure attributable to Letters of Credit issued by the applicable Issuing Bank will not, unless such
Issuing Bank shall so agree, exceed the LC Commitment of such Issuing Bank and (v) the LC Exposure will not exceed the greater of (A) $275,000,000 and (B) 25% of the Aggregate Commitment as then in effect. Notwithstanding the
foregoing, no Issuing Bank shall be required to issue any Letter of Credit if (x) any order, judgment or decree of any governmental authority shall enjoin or restrain, or by its terms purport to enjoin or restrain, such Issuing Bank from
issuing such Letter of Credit, (y) any applicable law or any order, request or directive (whether or not having the force of law) of any 

  
 30 

 
governmental authority with jurisdiction over such Issuing Bank shall prohibit, or request that such Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of
Credit in particular or impose upon such Issuing Bank any restriction, reserve or capital requirement with respect to such Letter of Credit not in effect on the Closing Date for which such Issuing Bank is not otherwise compensated (or assured to its
satisfaction that it will be compensated) hereunder or any unreimbursed loss, cost or expense not applicable to such Issuing Bank on the Closing Date, which such Issuing Bank deems in good faith to be material to it and for which such Issuing Bank
is not otherwise compensated (or assured to its satisfaction that it will be compensated) hereunder or (z) for Letters of Credit to be issued jointly for the account of either Borrower and any of its subsidiaries in accordance with
Section 2.6(a), the applicable Issuing Bank has not received documentation that it shall have reasonably requested in order to comply with its obligations under applicable “know your customer” and anti-money laundering rules and
regulations, including the USA Patriot Act, with respect to such subsidiaries. If the Required Lenders notify the Issuing Banks that a Default exists with respect to a requesting Borrower and instruct the Issuing Banks to suspend the issuance,
amendment, renewal or extension of Letters of Credit for the account of such Borrower, no Issuing Bank shall issue, amend, renew or extend any Letter of Credit for the account of such Borrower or the Company without the consent of the Required
Lenders until such notice is withdrawn by the Required Lenders (and each Lender that shall have delivered such notice agrees promptly to withdraw it at such time as no Default exists). 

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date
one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to earlier of the Maturity Date
for the applicable Borrower and the LC Commitment Termination Date for the applicable Issuing Bank; provided that any Letter of Credit may contain customary automatic renewal provisions agreed upon by the applicable Borrower and the
applicable Issuing Bank pursuant to which the expiration date of such Letter of Credit shall automatically be extended for a period of up to 12 months (but not to a date later than the date that is five Business Days prior to the earlier of the
Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, unless otherwise permitted pursuant to the immediately succeeding proviso), subject to a right on the part of such Issuing Bank to prevent any
such renewal from occurring by giving notice to the beneficiary in advance of any such renewal; provided, further that, with the prior consent of the Agent and the applicable Issuing Bank, a Letter of Credit may be issued or extended
with an expiration date beyond the fifth Business Day prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, in which case the applicable Borrower shall deposit on or prior
to the date 90 days prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank, in an account with such Issuing Bank, for the benefit of the Lenders and such Issuing Bank, as
cash collateral pursuant to documentation reasonably satisfactory to the Agent and such Issuing Bank, an amount in cash equal to 101% of the aggregate amount of all outstanding Letters of Credit issued for its account by such Issuing Bank that have
an expiration date later than the fifth Business Day prior to the earlier of the Maturity Date for the applicable Borrower and the LC Commitment Termination Date for such Issuing Bank. 

  
 31 

 (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a
participation in such Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Agent, for the account of such Issuing Bank, such Lender’s Pro Rata Share of each LC Disbursement made by such Issuing Bank and not reimbursed by the applicable Borrower on the date due as provided in
paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the applicable Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in
respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
 (e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower for the account such Letter of Credit was issued, severally and not jointly with
the other Borrower, shall reimburse such LC Disbursement by paying to the Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if such Borrower shall have
received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by such Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on
(i) the Business Day that such Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that such Borrower receives
such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $1,000,000, such Borrower may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.1 or 2.5 that such payment be financed with a Floating Rate Advance or a Swingline Loan to such Borrower in an equivalent amount and, to the extent so financed, such Borrower’s obligation to make such payment
shall be discharged and replaced by the resulting Floating Rate Advance or Swingline Loan. If such Borrower fails to make such payment when due, the Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from such
Borrower in respect thereof and such Lender’s Pro Rata Share thereof. Promptly following receipt of such notice, each Lender shall pay to the Agent its Pro Rata Share of the payment then due from such Borrower, in the same manner as provided in
Section 2.11 with respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to such Issuing Bank the amounts so received
by it from the Lenders. Promptly following receipt by the Agent of any payment from such Borrower pursuant to this paragraph, the Agent shall distribute such payment to such Issuing Bank or, to the extent that Lenders have made payments pursuant to
this paragraph to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement (other than the
funding of a Floating Rate Advance or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve such Borrower of its obligation to reimburse such LC Disbursement. 

  
 32 

 (f) Obligations Absolute. Each Borrower’s obligation to reimburse LC
Disbursements as provided in paragraph (e) of this Section in respect of Letters of Credit issued for its account shall be several and not joint with the other Borrower, shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein,
(ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a
Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but
for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, such Borrower’s obligations hereunder. None of the Agent, the Lenders or the Issuing Banks, or any of their respective
affiliates, directors, officers or employees, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of
any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the applicable Issuing Bank; provided that the foregoing shall not be construed to
excuse an Issuing Bank from liability to a Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by such
Borrower that are caused by such Issuing Bank’s wrongful honor or rejection of any drawing under such Letter of Credit to the extent arising out of the Issuing Bank’s gross negligence or willful misconduct (as finally determined by a court
of competent jurisdiction). In furtherance of the foregoing and without limiting the generality thereof, but subject to any non-waivable provisions of the laws and/or other rules to which a Letter of Credit is subject, the parties agree that, with
respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, an Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility
for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 

(g) Disbursement Procedures. The applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents
purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Agent and the applicable Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Bank has
made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve such Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC
Disbursement. 

  
 33 

 (h) Interim Interest. If an Issuing Bank shall make any LC Disbursement in respect of
any Letter of Credit, then, unless the Borrower for the account of which such Letter of Credit was issued shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each
day from and including the date such LC Disbursement is made to but excluding the date that such Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Floating Rate Advances; provided that, if such Borrower fails
to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.14 shall apply. Interest accrued pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on
and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment. 

(i) Cash Collateralization. If (i) a Default under Section 7.2 with respect to a Borrower shall occur and be continuing
or (ii) any other Default with respect to a Borrower shall occur and be continuing and the Required Lenders shall have terminated the Commitments insofar as they are available to such Borrower or accelerated the maturity of any Loans of such
Borrower, in either case as a result of such Default (and unless and until any such termination or acceleration has been rescinded), then on the Business Day that such Borrower receives notice from the Agent or the Required Lenders (or, if the
maturity of the Loans has been accelerated, Lenders with LC Exposures representing greater than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, such Borrower shall deposit in an account with the
Agent, in the name of the Agent and for the benefit of the Lenders, an amount in cash equal to 101% of the portion of the LC Exposure as of such date attributable to Letters of Credit issued for the account of such Borrower; provided that the
obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Default with respect to such Borrower
described in Section 7.6 or 7.7. Such deposit shall be held by the Agent as collateral for the payment and performance of the Obligations of such Borrower under this Agreement. The Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made only if and to the extent requested by such Borrower and then only at the option and sole discretion
of the Agent, and all at such Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Agent to
reimburse each Issuing Bank for LC Disbursements under outstanding Letters of Credit issued for the account of such Borrower for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of future
reimbursement obligations under Letters of Credit issued for the account of such Borrower or, if the maturity of the Loans has been accelerated (but subject to the consent of such Lenders with LC Exposures representing greater than 50% of the total
LC Exposure), be applied to satisfy other Obligations of such Borrower under this Agreement. If either Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of any event specified in clause (i) or
(ii) above with respect to such Borrower, such amount (to the extent not applied as aforesaid) shall be returned to such Borrower within three Business Days after all Defaults with respect to such Borrower have been cured or waived and, if
Loans or other Obligations (other than any unasserted contingent indemnity claims) of such Borrower have been accelerated, all such Loans and other Obligations of such Borrower have been repaid (or such acceleration has been

  
 34 

 
rescinded). If at any time the cash collateral of either Borrower shall exceed 101% of such portion of the LC Exposure as of such date attributable to Letters of Credit issued for the account of
such Borrower, the Agent shall apply such excess funds to the payment of such Borrower’s Obligations or (x) if no such Obligations are then due and owing and no Default with respect to such Borrower shall exist, shall release such excess
funds to such Borrower or (y) if no such Obligations are outstanding (other than contingent Obligations in respect of Letters of Credit which are fully collateralized and unasserted contingent indemnification claims), such excess amount shall
be released to such Borrower notwithstanding the existence of a Default in respect of such Borrower. 
 (j) Designation of
Additional Issuing Banks; Termination of Appointment of Issuing Banks. From time to time, the Borrowers may by notice to the Agent and the Lenders designate as additional Issuing Banks one or more Lenders that agree to serve in such capacity as
provided below. The acceptance by a Lender of any appointment as an Issuing Bank hereunder shall be evidenced by an agreement (an “Issuing Bank Agreement”), which shall be in a form satisfactory to the Borrowers and the Agent, shall
set forth the LC Commitment of such Lender and shall be executed by such Lender, the Borrowers and the Agent and, from and after the effective date of such agreement, (i) such Lender shall have all the rights and obligations of an Issuing Bank
under this Agreement and the other Loan Documents and (ii) references herein and in the other Loan Documents to the term “Issuing Bank” shall be deemed to include such Lender in its capacity as an Issuing Bank. If the Commitment
Termination Date shall be extended beyond the LC Commitment Termination Date of any Issuing Bank that is a Declining Lender, the appointment of such Issuing Bank shall be terminated effective as of the Existing Commitment Termination Date, at which
time the Borrowers shall pay any unpaid fees accrued for the account of the terminated Issuing Bank pursuant to Section 2.8.2. Notwithstanding the effectiveness of any such termination, the terminated Issuing Bank shall remain a party hereto
and shall continue to have all rights as an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such termination, but shall not issue any additional Letters of Credit. 

(k) Issuing Bank Reports to the Agent. Unless otherwise agreed by the Agent, each Issuing Bank shall, in addition to its
notification obligations set forth elsewhere in this Section, report in writing to the Agent (i) upon the reasonable request of the Agent, periodic activity (for such period or recurrent periods as shall be requested by the Agent) in respect of
Letters of Credit issued by such Issuing Bank, including all issuances, extensions, amendments and renewals, all expirations and cancelations and all disbursements and reimbursements, (ii) reasonably prior to the time that such Issuing Bank
issues, amends, renews or extends any Letter of Credit, the Borrower for the account of which such Letter of Credit is to be issued, the date of such issuance, amendment, renewal or extension, and the stated amount of the Letters of Credit issued,
amended, renewed or extended by it for the account of each Borrower and outstanding after giving effect to such issuance, amendment, renewal or extension (and whether the amounts thereof shall have changed), (iii) on each Business Day on which
such Issuing Bank makes any LC Disbursement, the date and amount of such LC Disbursement and the Letter of Credit to which it relates and (iv) on any Business Day on which a Borrower fails to reimburse an LC Disbursement required to be
reimbursed to such Issuing Bank on such day, the date of such failure and the amount of such LC Disbursement. 

  
 35 

 (l) LC Exposure Determination. For all purposes of this Agreement, the amount of a
Letter of Credit that, by its terms or the terms of any document related thereto, provides for one or more automatic increases in the stated amount thereof shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect
to all such increases, whether or not such maximum stated amount is in effect at the time of determination. 
 2.7. Types of
Advances. Revolving Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, selected by the applicable Borrower in accordance with Sections 2.11 and 2.12. Competitive Loans may be Eurodollar Rate Advances or
Fixed Rate Advances, or a combination thereof, selected by the applicable Borrower in accordance with Section 2.4. Each Swingline Loan shall be a Floating Rate Advance. 
 2.8. Facility Fee; Letter of Credit Fees; Reductions in Aggregate Commitment and Borrower Sublimits. 
 2.8.1 Facility Fee. Subject to Section 2.25, each Borrower agrees, severally and not jointly with the other Borrower, to pay to the Agent for the account of each Lender a facility fee (the
“Facility Fee”) at a per annum rate equal to such Borrower’s Applicable Fee Rate on its Contribution Percentage of such Lender’s Commitment (whether used or unused) from and including the Closing Date to and including the
Availability Termination Date for such Borrower, payable quarterly in arrears on each Payment Date hereafter and on the Availability Termination Date for such Borrower; provided, that if any Lender continues to have Revolving Credit Exposure
attributable to such Borrower hereunder after the Availability Termination Date for such Borrower (excluding any Revolving Credit Exposure in respect of LC Exposure which is cash collateralized hereunder), then the Facility Fee shall continue to
accrue on the aggregate principal amount of such Revolving Credit Exposure until such Lender ceases to have any such Revolving Credit Exposure, and shall be payable on demand. 

2.8.2 Letter of Credit Fees. Each Borrower agrees, severally and not jointly with the other Borrower, to pay
(i) to the Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit issued for the account of such Borrower (the “LC Participation Fee”), which shall accrue at the
Applicable Fee Rate on the average daily amount of that portion of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) attributable to Letters of Credit issued for the account of such Borrower
during the period from and including the Closing Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any such LC Exposure, and (ii) to each Issuing Bank
a fronting fee, which shall accrue at the rate or rates per annum separately agreed upon between such Borrower and such Issuing Bank on the average daily amount of the LC Exposure attributable to

  
 36 

 
Letters of Credit issued by such Issuing Bank for the account of such Borrower (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including
the Closing Date to but excluding the later of the date of termination of such Issuing Bank’s LC Commitment and the date on which there ceases to be any such LC Exposure attributable to Letters of Credit issued by such Issuing Bank for such
Borrower, as well as each Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit issued by such Issuing Bank for the account of such Borrower or processing of drawings thereunder. LC
Participation Fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after
the Closing Date; provided that all such fees accrued for the account of such Borrower shall be payable on the Availability Termination Date for such Borrower and any such fees accruing after the Availability Termination Date for such
Borrower shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this paragraph shall be payable promptly upon receipt of an invoice therefor in reasonable detail. 

2.8.3 Termination of and Reductions in Aggregate Commitment and Borrower Sublimits. The Commitments will
automatically terminate on the Commitment Termination Date. The Company (on behalf of itself and the Borrowing Subsidiary) may permanently reduce the Aggregate Commitment (with or without reducing either Borrower Sublimit), and (without limiting the
foregoing) the Borrowing Subsidiary or the Company, as applicable, may permanently reduce its respective Borrower Sublimit (with or without reducing the Aggregate Commitment), in each case, in whole or in part and without penalty or premium, ratably
among the Lenders in integral multiples of $5,000,000, upon at least three (3) Business Days’ written notice to the Agent, which notice shall specify, as applicable (a) the aggregate amount of any such reduction and/or (b) the
individual amount by which the applicable Borrower Sublimit shall be reduced, provided, however, that (i) the amount of the Aggregate Commitment may not be reduced below the Aggregate Outstanding Credit Exposure and (ii) the
Borrower Sublimit of either Borrower may not be reduced below the Borrower Credit Exposure of such Borrower. Any reduction of the Aggregate Commitment under this Section (other than the first sentence hereof) shall reduce ratably the Commitments of
all the Lenders. 
 2.9. Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of
$5,000,000 (and in a multiple of $1,000,000 if in excess thereof), and each Floating Rate Advance shall be in the minimum amount of $5,000,000 (and in a multiple of $1,000,000 if in excess thereof); provided, however, that (i) any
Floating Rate Advance to a 

  
 37 

 
Borrower may be in the amount of the Available Aggregate Commitment and (ii) any Floating Rate Advance to a Borrower may be in the amount equal to the lesser of the Available Aggregate
Commitment and the amount by which the Borrower Sublimit of such Borrower exceeds the Borrower Credit Exposure of such Borrower. Each Swingline Loan shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000.

 2.10. Optional Principal Payments. Each Borrower may from time to time pay, without penalty or premium, all
outstanding Floating Rate Advances of such Borrower, or any portion of such outstanding Floating Rate Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (or, if less, the remaining
outstanding principal amount of such Borrower’s Floating Rate Advances), upon at least one (1) Business Day’s prior notice to the Agent. Each Borrower may from time to time pay, subject to the payment of any funding indemnification
amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances of such Borrower, or any portion of such outstanding Eurodollar Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple
of $1,000,000 in excess thereof (or, if less, the remaining outstanding principal amount of such Borrower’s Eurodollar Advances), upon at least three (3) Business Days’ prior notice to the Agent; provided that no Competitive
Loan may be prepaid without the consent of the applicable Lender. Each Borrower may from time to time pay, without penalty or premium, any outstanding Swingline Loan upon giving notice thereof to the Swingline Lender not later than 12:00 noon, New
York City time, on the date of prepayment. Any optional payment of Advances (other than Competitive Loans and Swingline Loans) under this Section shall be applied ratably to the Advances (other than Competitive Loans and Swingline Loans) of all the
Lenders. 
 2.11. Method of Selecting Types and Interest Periods for New Revolving Advances; Funding of Loans. The
applicable Borrower shall select the Type of each Revolving Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto; provided that there shall be no more than five (5) Interest Periods in effect with
respect to all of the Revolving Loans of any single Borrower at any time, unless such limit has been waived by the Agent in its sole discretion. The applicable Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”)
not later than 11:30 a.m. (New York time) on the Borrowing Date of each Floating Rate Advance or on the third Business Day before the Borrowing Date for each Eurodollar Advance, specifying: 

 

	 	(i)	the Borrower requesting such Advance, 

  

	 	(ii)	the Borrowing Date, which shall be a Business Day, of such Advance, 

  

	 	(iii)	the aggregate amount of such Advance, 

  

	 	(iv)	the Type of Advance selected, and 

  

	 	(v)	in the case of each Eurodollar Advance, the Interest Period applicable thereto. 

 The Agent shall provide written notice of each request for borrowing under this Section 2.11 by 12:30 p.m. (New York time) on the Borrowing Date for each Floating Rate Advance or on the third
Business Day prior to the Borrowing Date for each Eurodollar Advance, as applicable. Not 

  
 38 

 
later than 2:00 p.m. (New York time) on each Borrowing Date, each Lender shall make available its Revolving Loan or Revolving Loans in Federal or other funds immediately available in
New York to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Lenders available to such Borrower at the Agent’s aforesaid address. 

2.12. Conversion and Continuation of Outstanding Revolving Advances; No Conversion or Continuation of Eurodollar Advances After
Default. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.12 or are repaid in accordance with Section 2.10.
Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Eurodollar Advance with an Interest Period of
30 days (unless such conversion would otherwise be prohibited hereunder, in which case such Eurodollar Advance shall be converted into a Floating Rate Advance) unless (x) such Eurodollar Advance is or was repaid in accordance with
Section 2.10 or (y) the applicable Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance either continue as a Eurodollar Advance
for the same or another Interest Period or be converted to a Floating Rate Advance. Subject to the terms of Section 2.9, a Borrower may elect from time to time to convert all or any part of an Advance of any Type into any other Type or Types of
Advances; provided that any conversion of any Eurodollar Advance shall be made on, and only on, the last day of the Interest Period applicable thereto. Notwithstanding anything to the contrary contained in this Section 2.12, during the
continuance of a Default with respect to a Borrower, the Agent may (or shall at the direction of the Required Lenders), by notice to such Borrower, declare that no Advance of such Borrower may be made, converted or continued as a Eurodollar Advance.
The applicable Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance to a Eurodollar Advance, continuation of a Eurodollar Advance, or conversion of a
Eurodollar Advance to a Floating Rate Advance not later than 11:00 a.m. (New York time) at least three (3) Business Days prior to the date of the requested conversion or continuation, specifying: 

 

	 	(i)	the requested date, which shall be a Business Day, of such conversion or continuation, 

 

	 	(ii)	the aggregate amount and Type of the Advance to be converted or continued, and 

 

	 	(iii)	the amount of the Advance to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto.

 This Section shall not apply to Competitive Loans and Swingline Loans, which may not be converted or continued. 

2.13. Interest Rates, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each
day from and including the date such Advance is made, to, but excluding, the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.12, as applicable, at a rate per annum equal to the Floating Rate applicable to such

  
 39 

 
Borrower for such day. Each Swingline Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Loan is made to but excluding the date it
is paid, at a rate per annum equal to the Floating Rate applicable to such Borrower for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance and on any Swingline Loan will take effect
simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of each Interest Period applicable thereto to (but not including)
the earlier of the last day of such Interest Period or the date it is paid in accordance with Section 2.10, at the applicable Eurodollar Rate as determined by the Agent as applicable to such Borrower’s Eurodollar Advance based upon the
applicable Borrower’s selections under Sections 2.11 and 2.12 and otherwise in accordance with the terms hereof. Each Fixed Rate Advance shall bear interest at the Fixed Rate applicable thereto. 

2.14. Rates Applicable After Default. Notwithstanding the foregoing, if any principal of any Loan is not paid when due, or if any
interest on any Loan or any fee or other amount payable by either Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise (in each case, after giving effect to any applicable grace period with respect to
such payment), such overdue amount shall bear interest, commencing on the day after such amount shall have become due in the case of principal and on the second Business Day after such amount shall have become due (in each case, after giving effect
to any applicable grace period with respect to such payment) in the case of other amounts, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% per annum plus the rate
otherwise applicable to such Loan as provided in Section 2.13 or (ii) in the case of any other amount, 2% per annum plus the rate applicable to Floating Rate Advances as provided in Section 2.13. 

2.15. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction or counterclaim, in
immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent reasonably in advance of the date any such payment is
required to be made, by 12:00 noon (New York time) on the date when due and shall be applied ratably by the Agent among the Lenders to which such Obligations are owing. Each payment delivered to the Agent for the account of any Lender shall be
delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent from such Lender. The Agent
is hereby authorized, at any time when a Default shall have occurred and be continuing, to charge the respective accounts of each Borrower maintained with JPMCB for each payment of principal, interest and fees owed by such Borrower as such payment
becomes due hereunder. 
 2.16. Noteless Agreement; Evidence of Indebtedness. (i) Each Lender shall maintain in
accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan made by such Lender to such Borrower from time to time, including the amounts of principal and interest
payable and paid to such Lender from time to time hereunder. 

  
 40 

	 	(ii)	The Agent shall also maintain accounts in which it will record (a) the date and the amount of each Loan made to each Borrower hereunder, the Type thereof and the
Interest Period (in the case of a Eurodollar Advance) with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder, (c) the effective date and
amount of each Assignment and Assumption delivered to and accepted by it pursuant to Section 12.1 and the parties thereto, (d) the amount of any sum received by the Agent hereunder from each Borrower and each Lender’s share thereof,
and (e) all other appropriate debits and credits as provided in this Agreement, including all fees, charges, expenses and interest. 

  

	 	(iii)	The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence absent manifest error
of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of such
Borrower to repay the Obligations in accordance with their terms. 

  

	 	(iv)	Any Lender may request that its Loans be evidenced by a promissory note in substantially the form of Exhibit E (a “Note”). In such event, the
applicable Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to
Section 12.1) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be
evidenced as described in paragraphs (i) and (ii) above. 

 2.17. Telephonic Notices. Each
Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good
faith believes to be acting on behalf of such Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. Each Borrower agrees to
deliver promptly to the Agent a written confirmation, signed by an Authorized Officer, of each telephonic notice. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the
Agent and the Lenders shall govern absent manifest error. 
 2.18. Interest Payment Dates; Interest and Fee Basis.
Interest accrued on each Floating Rate Advance shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the Closing Date, on any date on which such Floating Rate Advance is prepaid, whether due to
acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of each applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or
otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such 

  
 41 

 
Interest Period. Interest accrued on each Fixed Rate Loan shall be payable on the last day of the Interest Period applicable to the Advance of which such Loan is a part and, in the case of a
Fixed Rate Advance with an Interest Period of more than 90 days’ duration (unless otherwise specified in the applicable Competitive Bid Request), each day prior to the last day of such Interest Period that occurs at intervals of 90 days’
duration after the first day of such Interest Period, and any other dates that are specified in the applicable Competitive Bid Request as dates for payment of interest with respect to such Advance. Interest accrued on each Swingline Loan shall be
payable in arrears on the day that such Loan is repaid or is required to be paid. Interest accrued on any Advance that is not paid when due shall be payable on demand and on the date of payment in full. Interest on Eurodollar Advances, Fixed Rate
Loans and fees hereunder shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances and Swingline Loans shall be calculated for actual days elapsed on the basis of a 365/366-day year. Interest
shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to 12:00 noon (New York time) at the place of payment. If any payment of principal of or interest on an Advance, any
fees or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of principal payment, such extension of
time shall be included in computing interest, fees and commissions in connection with such payment. 
 2.19. Notification of
Advances, Interest Rates, Prepayments and Commitment Reductions; Availability of Loans. Promptly after receipt thereof, the Agent will notify each Lender in writing of the contents of each Aggregate Commitment or Borrower Sublimit reduction
notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The Agent will notify the applicable Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon
determination of such interest rate and will give each Borrower and each Lender prompt notice of each change in the Alternate Base Rate. 
 2.20. Lending Installations. Each Lender may, subject to its obligations under Section 3.7, book its Loans at any Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans and any Notes issued hereunder shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender
may, by written notice to the Agent and the Borrowers in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it and for whose account Loan payments are to be made. 

2.21. Non-Receipt of Funds by the Agent. Unless the applicable Borrower or a Lender, as the case may be, notifies the Agent prior
to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or any payment under Section 2.6(e) or (ii) in the case of a Borrower, a payment of principal, interest or fees
to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended
recipient in reliance upon such assumption. If such Lender or such Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the 

  
 42 

 
amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent
recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in
the case of payment by a Borrower, the interest rate applicable to the relevant Loan. 
 2.22. Replacement of Lender. If
(a) either Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender, (b) any Lender’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances
shall be suspended pursuant to Section 3.3, (c) any Lender is a Declining Lender, (d) any Lender is a Defaulting Lender or has a direct or indirect parent company that is the subject of a Bankruptcy Event, (e) any Lender invokes
Section 9.2 or (f) any Lender has advised that it will not consent to any waiver or amendment of this Agreement that requires the approval of all the Lenders or all affected Lenders and, upon the replacement of such non-consenting Lender,
the Lender replacing such non-consenting Lender shall consent to any such waiver or amendment and such approval (as to all Lenders or as to all affected Lenders, as applicable) shall be obtained (any Lender subject to any of the foregoing clauses
(a), (b), (c), (d), (e) or (f) being an “Affected Lender”), the Borrowers may elect (i) in the case of the foregoing clauses (a), (b), (d) or (e) (but only if such additional payment continues to be
required, such suspension continues to be effective, such Lender continues to be a Defaulting Lender or the direct or indirect parent company of such Lender continues to be the subject of a Bankruptcy Event or Section 9.2 continues to be
invoked), to terminate the Commitment of such Affected Lender (without affecting the Commitments of the other Lenders), or (ii) in all cases, to replace such Affected Lender and its Commitment (including with one or more Lenders (which may be
current Lenders) having lesser, equivalent or greater aggregate Commitments than those of the Affected Lenders being so replaced); provided that (A) in the case of any termination of the Commitment of an Affected Lender, no Default or
Unmatured Default shall have occurred and be continuing at the time of such termination, (B) in the case of any replacement of an Affected Lender, one or more banks or other entities which are approved by the Borrowers, the Agent, each Issuing
Bank and the Swingline Lender (such approval not to be unreasonably withheld or delayed) shall purchase for cash at face amount the Outstanding Credit Exposure of the Affected Lender pursuant to an Assignment and Assumption substantially in the form
of Exhibit C (and, if not already a Lender, shall become a Lender for all purposes under this Agreement) and assume the Commitment and all obligations of the Affected Lender as of the time of such replacement and comply with the requirements of
Section 12.1 applicable to assignments, and (C) in the case of any termination or replacement of the Commitment of an Affected Lender, each Borrower shall pay to such Affected Lender in immediately available funds on the day of termination
or replacement, to the extent not paid by a replacement Lender pursuant to the preceding clause (B), all principal, interest, fees and other amounts (other than unasserted contingent indemnity obligations) then outstanding or accrued but unpaid for
the account of such Affected Lender to the extent constituting Obligations of such Borrower hereunder, including payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and, except in the case of a Defaulting Lender, an amount, if any,
equal to the payment which would have been due to such Lender on the day of such termination or replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date pursuant to Section 2.10. Notwithstanding the
foregoing, the Borrowers may not terminate the Commitment of an Affected Lender if, after giving effect to such 

  
 43 

 
termination, (x) the Aggregate Outstanding Credit Exposure would exceed the Aggregate Commitment (as then in effect giving effect to any increases thereof effected in accordance with the
terms hereof) or (y) the Borrower Credit Exposure of either Borrower would exceed the Borrower Sublimit of such Borrower. 

2.23. Extension of Commitment Termination Date. The Company, on behalf of both Borrowers, may, on not more than two occasions
during the term of this Agreement, by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders) delivered not fewer than 45 days, and not more than 60 days, before any anniversary of the Closing Date, request that the
Lenders extend the then effective Commitment Termination Date (the “Existing Commitment Termination Date”) for an additional period of one year, effective as of a date specified in such notice. Each Lender shall, by notice to the
Company and the Agent given not later than the 20th day after the date of the Agent’s receipt of the Company’s notice, advise the Company whether or not it agrees to the requested extension (each Lender agreeing to a requested extension
being called a “Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender that has not so advised the Company and the Agent by such day shall be
deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to a Commitment Termination Date extension request, then the Commitment Termination Date shall, as to
the Consenting Lenders, be extended to the first anniversary of the Existing Commitment Termination Date. The decision of any Lender to agree or withhold agreement to any extension request shall be at the sole discretion of such Lender. The
Commitment of any Declining Lender shall terminate on the Existing Commitment Termination Date. The principal amount of any outstanding Loans made by Declining Lenders, together with any accrued interest thereon and any accrued fees and other
amounts payable to or for the accounts of such Declining Lenders hereunder, shall be due and payable on the Existing Commitment Termination Date, and on the Existing Commitment Termination Date each Borrower shall also make such other prepayments of
its Loans as shall be required in order that, after giving effect to such prepayments and to the termination of the Commitments of, and all payments to, Declining Lenders pursuant to this sentence, (a) the Aggregate Outstanding Credit Exposure
shall not exceed the Aggregate Commitment, (b) the Revolving Credit Exposure of any Lender shall not exceed its Commitment and (c) the Borrower Credit Exposure of either Borrower shall not exceed the Borrower Sublimit of such Borrower.
Notwithstanding the foregoing, no extension of the Commitment Termination Date shall become effective under this Section unless (i) on the effective date of such extension, the conditions set forth in Section 4.2 (it being understood and
agreed that (A) all references to “Credit Extension Date” therein shall be deemed to refer to such effective date and (B) all references to the “Closing Date” in (x) Section 4.2.2 as it relates to Sections
5.5, 5.7 and 5.14(ii) and (y) in Sections 5.5, 5.7 and 5.14(ii) shall be deemed to refer to such effective date for purposes of determining satisfaction of the conditions set forth in Section 4.2 as of such date) shall be satisfied as of
such date (as though the effectiveness of such extension were a Credit Extension) and (ii) the Agent shall have received a certificate to that effect dated such effective date and executed by an Authorized Officer of the Company. 

2.24. Extension of Borrowing Subsidiary Maturity Date. The Borrowing Subsidiary may, by notice (a “Maturity Date Extension
Request”) to the Agent (which shall promptly deliver a copy to each of the Lenders) given at any time (and from time to time without limitation) not more than 90 days and not less than 30 days prior to its then-current Maturity 

  
 44 

 
Date (the “Existing Maturity Date”), request an extension of such Maturity Date to a date not more than 364 days after the Existing Maturity Date specified in such notice, but in
no event to a date later than the Commitment Termination Date. Each Lender shall, by notice to such Borrowing Subsidiary, the Company and the Agent given not later than the 20th day after the date of the Agent’s receipt of such Maturity Date
Extension Request, advise such Borrowing Subsidiary and the Company whether or not it agrees to the requested extension (and, except as set forth in the following proviso, any Lender that has not so advised such Borrowing Subsidiary, the Company and
the Agent by such day shall be deemed to have declined to agree to such extension); provided, that notwithstanding the foregoing, (i) so long as the Borrowing Subsidiary shall have received FERC authorization for short-term financings
for the period through the requested Maturity Date, then upon written notice thereof to the Agent (either concurrently with the delivery of the Maturity Date Extension Request or at anytime thereafter but prior to the then effective Maturity Date)
and satisfaction of the conditions set forth in the following sentence, each Lender shall be obligated to consent (and shall be deemed to have consented) to such extension and the Maturity Date for such Borrowing Subsidiary shall be deemed extended
to the date requested by the Borrowing Subsidiary in such notice without any further consent or approval of any Lender, any Issuing Bank or the Agent and (ii) upon the Borrowing Subsidiary’s receipt of the necessary approvals from the
Illinois Commerce Commission authorizing such Borrowing Subsidiary to borrow hereunder through the Commitment Termination Date, then upon written notice thereof to the Agent and satisfaction of the conditions set forth in the following sentence, the
Maturity Date for such Borrowing Subsidiary shall automatically be extended to the Commitment Termination Date without the consent or approval of or any further action by any Lender, any Issuing Bank or the Agent. If requested by the Borrowing
Subsidiary, the effectiveness of any such extension shall be confirmed by the Agent in writing to the Borrowing Subsidiary. Unless otherwise consented to by the Required Lenders, no extension of such Maturity Date pursuant to this Section 2.24
shall become effective unless the Agent shall have received (1) copies of any approvals by FERC and/or the Illinois Commerce Commission, as applicable, required for such extension and (2) legal opinions (including from Borrowing
Subsidiary’s in-house counsel) in substantially the form of those delivered pursuant to Section 4.1.7 solely as to the fact that any and all FERC, Illinois Commerce Commission and/or other regulatory approvals, as applicable, required to
permit borrowings by and Credit Extensions to the Borrowing Subsidiary in the amount of its Borrower Sublimit through the extended Maturity Date have been obtained (to be in form and substance (to the extent of the limited scope thereof set forth
above) reasonably satisfactory to the Agent). 
 2.25. Defaulting Lenders. (a) Notwithstanding any provision of this
Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply: 
  

	 	(i)	Facility Fees shall cease to accrue on the unused portion of such Defaulting Lender’s Commitment. 

 

	 	(ii)	The Commitment and Outstanding Credit Exposure of such Defaulting Lender shall not be included in determining whether the Required Lenders or other requisite Lenders
have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 8.2); provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender
shall require the consent of such Defaulting Lender (in such case, to the extent such Defaulting Lender is an affected Lender). 

  
 45 

	 	(iii)	Unless a Default or an Unmatured Default shall have occurred and be continuing, all or any part of such Defaulting Lender’s Swingline Exposure and LC Exposure
shall be reallocated among the non-Defaulting Lenders in accordance with their Pro Rata Shares of the Aggregate Commitment, but only to the extent the sum of all non-Defaulting Lenders’ Outstanding Credit Exposures plus such Defaulting
Lender’s Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments. 

  

	 	(iv)	If the LC Exposure of such Defaulting Lender is reallocated pursuant to clause (iii) above, then the LC Participation Fees payable to the Lenders pursuant to
Section 2.8.2 shall be adjusted in accordance with such reallocation. 

  

	 	(v)	If (or to the extent) the reallocation described in clause (iii) above cannot, or can only partially, be effected, each Borrower shall within one Business Day
following notice by the Agent (x) first, prepay the Defaulting Lender’s non-reallocated portion of the Swingline Exposure attributable to Swingline Loans made to such Borrower and (y) second, cash collateralize for the
benefit of the Issuing Banks such Borrower’s obligations corresponding to the portion of such Defaulting Lender’s non-reallocated LC Exposure that is attributable to Letters of Credit issued for the account of such Borrower (in each case,
as determined after giving effect to any partial reallocation pursuant to clause (iii) above) in accordance with the procedures set forth in Section 2.6(i) for so long as such LC Exposure is outstanding. 

 

	 	(vi)	If a Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to clause (v) above, such Borrower shall not be required to pay
any fees to such Defaulting Lender pursuant to Section 2.8.2 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized. 

 

	 	(vii)	The Agent shall adjust the allocation of payments hereunder to ensure that a Defaulting Lender does not receive payment in respect of any Loan or LC Disbursement that
it did not fund or to reflect any of the actions or adjustments referred to in this Section 2.25. 

 (b) If
(i) a Bankruptcy Event with respect to the parent company of any Lender shall occur following the date hereof and for so long as such event shall continue or (ii) the Swingline Lender or any Issuing Bank shall have a good faith belief that
any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Swingline Lender shall not be required to fund any Swingline Loan and such Issuing Bank shall not be
required to issue, amend or increase any Letter of Credit, unless the Swingline Lender or such Issuing Bank, as the case may be, shall have entered into arrangements with the applicable Borrower or such Lender reasonably satisfactory to the
Swingline Lender or such Issuing Bank, as the case may be, to mitigate the risk to it in respect of such Lender failing to satisfy its participating interest therein. 

  
 46 

 (c) In the event that the Agent, each Borrower, the Swingline Lender and each Issuing Bank
agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s
Commitment and on such date such Lender shall purchase at par such of the Loans (other than Competitive Loans and Swingline Loans) and participations in LC Disbursements of the other Lenders as the Agent shall determine may be necessary in order for
such Lender to hold such Loans in accordance with its Pro Rata Share. 
 (d) Except as expressly provided in this
Section 2.25 in connection with the obligations of the Swingline Lender or the Issuing Banks, the obligation of each Lender, Issuing Bank and Swingline Lender to fund the full amount of its Commitment and to make Loans, Advances and other
extensions of credit hereunder shall not be released or diminished in any respect by any other Lender becoming a Defaulting Lender. 
 (e) None of the foregoing provisions of this Section 2.25 shall be deemed to effect, diminish or release any rights, claims or causes of action the Borrowers may have against any Lender that becomes
a Defaulting Lender. 
 2.26. Commitment Increases. (a) The Borrowers may from time to time (and more than one
time), by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders), executed by the Borrowers and one or more financial institutions (any such financial institution referred to in this Section being called an
“Augmenting Lender”), which may include any Lender, cause new Commitments to be extended by the Augmenting Lenders or cause the existing Commitments of the Augmenting Lenders to be increased, as the case may be (the aggregate amount
of such increase for all Augmenting Lenders on any single occasion being referred to as a “Commitment Increase”), in an amount for each Augmenting Lender set forth in such notice; provided that (i) the amount of each
Commitment Increase shall be not less than $10,000,000, except to the extent necessary to utilize the remaining unused amount of increase permitted under this Section 2.26(a) and (ii) the Aggregate Commitment shall not exceed
$1,300,000,000 after giving effect to the effectiveness of any Commitment Increase. The decision of any Lender to become an Augmenting Lender shall be at the sole discretion of such Lender. Each Augmenting Lender shall be subject to the approval of
the Agent, each Issuing Bank and the Swingline Lender (which approval shall not be unreasonably withheld or delayed) and shall not be subject to the approval of any other Lenders, and the Company and each Augmenting Lender shall execute all such
documentation as the Agent shall reasonably specify to evidence the Commitment of such Augmenting Lender and/or its status as a Lender hereunder (such documentation in respect of any Commitment Increase together with the notice of such Commitment
Increase being referred to collectively as the “Commitment Increase Amendment” in respect of such Commitment Increase). 
 (b) Upon each Commitment Increase pursuant to this Section, (i) each Lender immediately prior to such increase will automatically and without further act be deemed to have assigned to each Augmenting
Lender providing a portion of such Commitment Increase, and 

  
 47 

 
each such Augmenting Lender will automatically and without further act be deemed to have assumed, a portion of such Lender’s participations hereunder in outstanding Letters of Credit such
that, after giving effect to such Commitment Increase and each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding participations hereunder in Swingline Loans and Letters of Credit held by each Lender
(including each such Augmenting Lender) will (subject to Section 2.25) equal such Lender’s Pro Rata Share and (ii) if, on the date of such Commitment Increase, there are any Revolving Loans outstanding, the parties hereto shall, at
the request of the Agent, take actions agreed upon by the Agent and the Company that will result, within a period acceptable to the Agent and the Company, in the outstanding Revolving Loans being held by the Lenders ratably in accordance with their
Commitments. In determining the actions to be taken (which may include the prepayment and reborrowing of all or a portion of such Revolving Loans and/or the making of Revolving Loans on a non-pro-rata basis by Augmenting Lenders for the balance of
Interest Periods in progress and at rates reflecting the Eurodollar Base Rate at the time for loans of such duration), the Agent and the Lenders will endeavor to minimize breakage costs for which the Borrowers must compensate the Lenders to the
extent practicable without undue complexity or administrative burdens on the Agent or the Lenders. The Agent and the Lenders hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this
Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. 
 (c) Commitment
Increases and new Commitments created pursuant to this Section 2.26 shall become effective on the date specified in the notice delivered by the Company pursuant to the first sentence of paragraph (a) above or on such other date as agreed
upon by the Company, the Agent and the applicable Augmenting Lenders. 
 (d) Notwithstanding the foregoing, no increase in the
Commitments (or in any Commitment of any Lender) or addition of an Augmenting Lender shall become effective under this Section unless (i) on the date of such increase, the conditions set forth in Section 4.2 (it being understood and agreed
that (A) all references to “Credit Extension Date” therein shall be deemed to refer to the date of such Commitment Increase and (B) all references to the “Closing Date” in Sections 5.5, 5.7 and 5.14(ii) shall be deemed
to refer to the date of such Commitment Increase) shall be satisfied as of such date (as though the effectiveness of such increase were a Credit Extension) and the Agent shall have received a certificate to that effect dated such date and executed
by an Authorized Officer of the Company, and (ii) the actions referred to in paragraph (b)(ii) of this Section 2.26 shall have been agreed upon by the Agent and the Company (provided, however, that the prepayment and
reborrowing on the date of such Commitment Increase of all Revolving Loans then outstanding shall be deemed to satisfy the condition specified in this clause (ii)).

 ARTICLE III 
 YIELD PROTECTION; TAXES 
 3.1. Yield Protection. If any Change in
Law: 
 3.1.1 subjects any Recipient to any Taxes (other than Indemnified Taxes and Excluded Taxes) on its
Loans, Loan principal, Letters of Credit, Commitment or other obligations hereunder, or its deposits, reserves, other liabilities or capital attributable thereto, or 

3.1.2 imposes, modifies or deems applicable any reserve, assessment, insurance charge, special deposit, compulsory loan
or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Issuing Bank, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in
determining the interest rate applicable to Eurodollar Advances), or 
 3.1.3 impose on any Lender, any Issuing
Bank or any applicable Lending Installation or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or such Lending Installation or any Letter of Credit or
participation therein, 
 and the result of any of the foregoing is to increase the cost to the Agent, such Lender or Issuing Bank or such
Lending Installation of making, converting to, continuing or maintaining its Commitment, any Loan or Letter of Credit or any participation therein or to reduce the amount of any sum received or receivable by the Agent, such Lender or Issuing Bank or
such Lending Installation hereunder, then, within fifteen (15) days after the submission of the written statement required by Section 3.6 by the Agent or such Lender or Issuing Bank or such Lending Installation, the Borrowers shall pay the
Agent or such Lender or Issuing Bank or such Lending Installation such additional amount or amounts as will compensate it for such increased cost or reduction in amount received. 

3.2. Changes in Capital Adequacy and Liquidity Requirements. If any Lender or Issuing Bank determines that any Change in Law
affecting such Lender or Issuing Bank or any Lending Installation of such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding capital or liquidity requirements has had or would have the effect of reducing the rate
of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitment of such Lender or the Loans made by, or
participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company
could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Bank’s policies and the policies of such Lender’s or Issuing Bank’s holding company with respect to capital adequacy or
liquidity), then, within fifteen (15) days after the submission of the written 

  
 49 

 
statement required by Section 3.6 by such Lender or Issuing Bank, the Borrowers shall pay such Lender or Issuing Bank the amount applicable to such Borrower necessary to compensate such
Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company for any such reduction suffered. 
 3.3.
Availability of Types of Advances. If prior to the first day of any Interest Period, the Agent shall give telecopy or telephonic notice thereof to the Borrowers and the Lenders that: 

(a) the Agent shall have determined (which determination shall be conclusive and binding upon the Borrowers) that, by reason of
circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the interest rate applicable to Eurodollar Advances for such Interest Period, or 

(b) the Agent shall have received notice from the Required Lenders that the interest rate for Eurodollar Advances determined or to be
determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively determined by such Lenders) of making or maintaining their affected Eurodollar Advances during such Interest Period, then
(x) any Eurodollar Advances requested to be made on the first day of such Interest Period shall be made as Floating Rate Advances, (y) any Floating Rate Advances that were to have been converted on the first day of such Interest Period to
Eurodollar Advances shall be continued as Floating Rate Advances and (z) any outstanding Eurodollar Advances shall be converted, on the last day of the then-current Interest Period, to Floating Rate Advances. Until such notice has been
withdrawn by the Agent, no further Eurodollar Advances shall be made or continued as such, nor shall any Borrower have the right to convert Floating Rate Advances to Eurodollar Advances. 

3.4. Funding Indemnification. If any payment of a Eurodollar Advance or a Fixed Rate Loan occurs on a date which is not the last
day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made or continued, a Fixed Rate Loan is not made or a Floating Rate Advance is not converted into a Eurodollar Advance on
the date specified by the applicable Borrower for any reason other than default by the Lenders, a Eurodollar Advance or Fixed Rate Loan is not prepaid on the date specified by such Borrower for any reason, or a Eurodollar Advance is prepaid by such
Borrower without such Borrower providing at least three (3) Business Days’ prior notice to the Agent for any reason, such Borrower will severally, and not jointly with the other Borrower, indemnify each Lender for any loss or cost incurred
by such Lender resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance or Fixed Rate Loan as determined by such Lender (if and to the extent such Lender, in its sole
discretion, elects to impose such a charge). Such loss or cost to any Lender in liquidating or employing deposits acquired to fund or maintain any such Eurodollar Advance or Fixed Rate Loan shall be an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the Eurodollar Rate that would have been applicable to such Loan (but not including the Applicable Margin
applicable thereto), for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such 

  
 50 

 
Lender on such amount by placing such amount on deposit at the commencement of such period for a comparable period with leading banks in the London interbank eurodollar market. Notwithstanding
the foregoing, a Defaulting Lender required to assign its Loans pursuant to Section 2.22 shall not be entitled to compensation under this Section 3.4 in connection with any such assignment. 

3.5. Taxes. 
 (a) Any and all payments by or on account of any obligation of each Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If
any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled
to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant governmental authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by each Borrower
shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 3.5) the applicable Recipient receives an amount
equal to the sum it would have received had no such deduction or withholding been made. As soon as practicable after any payment of Taxes by either Borrower to a governmental authority pursuant to this Section 3.5, such Borrower shall deliver
to the Agent the original or a certified copy of a receipt issued by such governmental authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent. 

(b) The Borrowers shall timely pay to the relevant governmental authority in accordance with applicable law, or at the option of the
Agent timely reimburse it for, Other Taxes. 
 (c) The Borrowers shall jointly and severally indemnify each Recipient, within 20
days after written demand therefor (in each case setting forth the basis therefor and the manner of determination thereof), for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts
payable under this Section 3.5) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified
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 either Borrower by a Lender (with a copy to the Agent), or by the Agent on its own
behalf or on behalf of a Lender, shall be conclusive absent manifest error. 
 (d) Each Lender shall severally indemnify the
Agent, within 20 days after written demand therefor (in each case setting forth the basis therefor and the manner of determination thereof), for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrowers
have not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of the Borrowers to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.1(c)
relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable

  
 51 

 
expenses arising therefrom or with respect thereto, whether or not such 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 any Lender, as applicable, by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any
Loan Document or otherwise payable by the Agent to such Lender from any other source against any amount due to the Agent under this Section 3.5(d) 
 (e) (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the applicable Borrower and the Agent,
at the time or times set forth herein or as are reasonably requested by such Borrower or the Agent, such properly completed and executed documentation reasonably requested by such Borrower or the Agent as will permit such payments to be made without
withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the applicable Borrower or the Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by such Borrower
or the Agent as will enable such Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the
completion, execution and submission of such documentation (other than such documentation set forth in Sections 3.5(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or
submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. 
  

	 	(ii)	Without limiting the generality of the foregoing, in the event that either Borrower is a U.S. Person, 

(A) any Lender that is a U.S. Person shall deliver to such Borrower and the Agent on or prior to the date on which such
Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth herein or upon the reasonable request of the Borrower or the Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S.
federal backup withholding tax; 
 (B) any Non-U.S. Lender shall, to the extent it is legally entitled to do so,
deliver to such Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Non-U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth
herein or upon the reasonable request of such Borrower or the Agent), whichever of the following is applicable: 

(1) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party
(x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax
treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other
income” article of such tax treaty; 

  
 52 

 (2) executed originals of IRS Form W-8ECI; 

(3) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under
Section 881(c) of the Code, (x) a certificate to the effect that such Non-U.S. Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the
meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form
W-8BEN; or 
 (4) to the extent a Non-U.S. Lender is not the beneficial owner, executed originals of IRS Form
W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Non-U.S. Lender is a
partnership and one or more direct or indirect partners of such Non-U.S. Lender are claiming the portfolio interest exemption, such Non-U.S. Lender may provide a U.S. Tax Compliance Certificate on behalf of each such direct and indirect partner;

 (C) any Non-U.S. Lender shall, to the extent it is legally entitled to do so, deliver to each Borrower and the
Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter as set forth herein or upon the reasonable request of
either Borrower or the Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as
may be prescribed by applicable law to permit the Borrowers and the Agent to determine the withholding or deduction required to be made; and 
 (D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements
of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to each Borrower and the Agent at the time or times prescribed by law and at such time or times reasonably requested by
either Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by either Borrower or the Agent as may be
necessary for Borrowers and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.
Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

  
 53 

 Each Lender agrees that if any form or certification it previously delivered
expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so. 

(f) 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 this Section 3.5 (including by the payment of additional amounts pursuant to this Section 3.5), 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 3.5 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 3.5(f) (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 3.5(f), in no
event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 3.5(f) 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 indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 3.5(f) 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. 
 (g) Each
party’s obligations under this Section 3.5 shall survive the resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender and the termination of the Commitments and the repayment, satisfaction or
discharge of all obligations under any Loan Document. 
 (h) For purposes of this Section 3.5, (i) the term
“Lender” includes any applicable Lending Installation and any Issuing Bank and (ii) the term “applicable law” includes FATCA. 
 3.6. Statements as to Claims; Survival of Indemnity. The Agent, each Lender or each Issuing Bank, as the case may be, shall deliver a written statement to the applicable Borrower (with a copy to
the Agent) as to each amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth an explanation in reasonable detail of the manner in which such Lender determined such amount and shall be final, conclusive
and binding on such Borrower in the absence of manifest error, and upon the reasonable request of such Borrower, such Lender shall promptly provide supporting documentation describing and/or evidencing the applicable event giving rise to such amount
to the extent not inconsistent with such Lender’s policies or applicable law. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through
the purchase of a deposit of the type, currency and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the
amount specified in the written statement of any Lender shall be payable within fifteen (15) days (or, in the case of Section 3.5, twenty (20) days) after receipt by the applicable Borrower of such written statement, unless subject to
a 

  
 54 

 
good faith dispute by such Borrower, notice and details of which were provided to the affected Lender prior to such due date. The obligations of each Borrower under Sections 3.1, 3.2, 3.4 and 3.5
shall survive payment of the Obligations and termination of this Agreement. Notwithstanding the foregoing, (a) the Borrowers shall not be responsible for any reimbursement of any such amount under Section 3.1, 3.2, 3.4 or 3.5 which shall
have accrued and of which the Agent or the applicable Lender or Issuing Bank, as the case may be, shall have become aware more than 180 days prior to its delivery to the Borrower of notice requesting reimbursement thereof and (b) none of the
Agent, any Lender or any Issuing Bank will make any claim (nor shall any Borrower have any liability) under Section 3.1, 3.2 or 3.5 unless the Agent, such Lender or such Issuing Bank, as applicable, shall have determined that the making of such
claim is consistent with its general practices under similar circumstances in respect of similarly situated borrowers under credit agreements entitling it to make such claims. 
 3.7. Alternative Lending Installation. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability
of the Borrowers to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. A
Lender’s designation of an alternative Lending Installation shall not affect the Borrowers’ rights under Section 2.22 to replace a Lender. 
 3.8. Allocation of Amounts Payable Among Borrowers. Each amount payable by “the Borrowers” under this Article shall be an obligation of, and shall be discharged by (a) to the extent
arising out of acts, events and circumstances related to a particular Borrower, such Borrower and (b) otherwise, both Borrowers, with each Borrower being severally liable for such Borrower’s Contribution Percentage of such amount,
provided that the Company agrees that, if the Borrowing Subsidiary shall fail to pay any amount owed by it under clause (b) of this Section after a demand shall have been made by the Person to which such amount is owed, the Company shall
promptly pay such amount (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of such Borrowing Subsidiary under this Section).

ARTICLE V 

REPRESENTATIONS AND WARRANTIES 
 Each Borrower severally, as to itself and, as applicable, its Subsidiaries, and not jointly with the other Borrower or its Subsidiaries, hereby represents and warrants to each Lender, each Issuing Bank
and the Agent: 
 5.1. Existence and Standing. Such Borrower and each of its Subsidiaries (other than any Project Finance
Subsidiary, Non-Material Subsidiary or SPC) is a corporation, partnership (in the case of Subsidiaries only) or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such
concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted, other than the
failure of any such Borrower or any of its Subsidiaries to so be in good standing or to be qualified to transact business in any such jurisdiction to the extent such failure could not reasonably be expected to result in a Material Adverse Effect
with respect to such Borrower. 
 5.2. Authorization and Validity. Such Borrower has the power and authority and legal
right to execute and deliver the Loan Documents and to perform its obligations thereunder. The execution and delivery by such Borrower of the Loan Documents and the performance of its obligations thereunder have been duly authorized by proper
proceedings, and the Loan Documents to which such Borrower is a party constitute legal, valid and binding obligations of such Borrower enforceable against such Borrower in accordance with their terms, except as enforceability may be limited by
(i) bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization or similar laws relating to or affecting the enforcement of creditors’ rights generally, (ii) general equitable principles (whether considered in a
proceeding in equity or at law) and (iii) requirements of reasonableness, good faith and fair dealing. 
 5.3. No
Conflict. The execution and delivery by such Borrower of the Loan Documents, the consummation of the transactions therein contemplated and compliance with the provisions thereof (i) do not require any consent or approval of, registration or
filing with or any other action by any governmental authority, except such as have been obtained or made and are in full force and effect or the failure to have obtained or made which could not reasonably be expected to result in a Material Adverse
Effect and (ii) will not violate (a) any law, rule, 

  
 58 

 
regulation, order, writ, judgment, injunction, decree or award binding on such Borrower or any of its Subsidiaries the violation of which is known to, or could reasonably be expected to, have a
Material Adverse Effect with respect to such Borrower, (b) such Borrower’s or any Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization,
by-laws, or operating agreement or other management agreement, as the case may be, or (c) the provisions of the Union Electric Credit Agreement or any indenture or the material provisions of any material instrument or any material agreement to
which such Borrower or any of its Subsidiaries is a party or is subject, or by which it or its Property is bound, or result in or require the creation or imposition of any Lien in, of or on the Property of such Borrower or any of its Subsidiaries
pursuant to the terms of the Union Electric Credit Agreement or any such indenture, instrument or agreement. 
 5.4.
Financial Statements. The consolidated financial statements of such Borrower, audited by PricewaterhouseCoopers LLP, as of and for the fiscal year ended December 31, 2011, and the unaudited consolidated balance sheets of such Borrower as
of March 31, 2012, and June 30, 2012, and the related unaudited statement of income and statement of cash flows for the periods then ended, copies of which have been furnished to each Lender, were prepared in accordance with generally
accepted accounting principles in effect on the dates such statements were prepared (subject in the case of such balance sheets and statements of income for the periods ended March 31, 2012, and June 30, 2012, to the absence of footnotes
and to year-end audit adjustments) and fairly present in all material respects the consolidated financial condition and results of the operations of such Borrower and its subsidiaries, taken as a whole, at such dates and the consolidated results of
its operations for the periods then ended. Except as disclosed in the financial statements referred to above or in the notes thereto or on Schedule 5 hereto, neither such Borrower nor any of its Subsidiaries has as of the Closing Date any
material contingent liabilities. 
 5.5. Material Adverse Change. As of the Closing Date, since December 31, 2011,
there has been no change in the business, Property, condition (financial or otherwise) or results of operations of such Borrower and its Subsidiaries (other than any Project Finance Subsidiary), taken as a whole, that could reasonably be expected to
have a Material Adverse Effect with respect to such Borrower, except for the Disclosed Matters. 
 5.6. Taxes. Such
Borrower and each of its Subsidiaries has timely filed complete and correct U.S. federal and all other applicable material foreign, state and local tax returns required by law and has paid when due all U.S. federal and all other applicable material
foreign, state and local taxes, assessments and governmental charges and levies upon it or its income, profits or Property, except (a) those which are being contested in good faith by appropriate proceedings and with respect to which adequate
reserves have been recorded in accordance with Agreement Accounting Principles or (b) where the failure to make any such filings or payments could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

 5.7. Litigation and Contingent Obligations. As of the Closing Date, other than the Disclosed Matters, there is no
litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of its officers, threatened against or affecting such Borrower or any of its Subsidiaries that could reasonably be expected to have a
Material Adverse Effect with respect to such Borrower or that seeks to prevent, enjoin or delay the making of any Loans to such Borrower. 

  
 59 

 5.8. Subsidiaries. Schedule 1 contains an accurate list of all Subsidiaries (other
than Non-Material Subsidiaries) of such Borrower as of the Closing Date, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by such Borrower or other
Subsidiaries of such Borrower. 
 5.9. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when
taken together with all other ERISA Events that have occurred or are reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 

5.10. Accuracy of Information. The written information, exhibits or reports (other than budgets, forecasts, projections and
forward looking statements (collectively, “Projections”)) with respect to such Borrower furnished to the Agent or to any Lender in connection with the negotiation of, or compliance with, the Loan Documents as of the date prepared,
and the information with respect to such Borrower communicated by responsible officers of such Borrower to attendees generally at any meeting or conference call of Lenders or prospective Lenders (including any due diligence meeting or call)
scheduled or arranged by the Agent as of the date communicated, do not, when taken as a whole, contain any material misstatement of any material fact or omit to state any material fact necessary to make the statements contained therein, in light of
the circumstances in which they were made, not materially misleading as of such date. The Projections with respect to such Borrower furnished to the Agent or to any Lender in connection with the negotiation of, or compliance with, the Loan Documents
as of the date furnished have been prepared in good faith based upon assumptions believed by such Borrower to be reasonable at the time such Projections were prepared. 
 5.11. Regulation U. Neither such Borrower nor any of its Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose, whether
immediate, incidental or ultimate, of buying or carrying margin stock (as defined in Regulation U), and after applying the proceeds of each Advance, margin stock (as defined in Regulation U) will constitute less than 25% of the value of those assets
of such Borrower and its Subsidiaries that are subject to any limitation on sale or pledge or any other restriction hereunder. 

5.12. Compliance With Laws. Except for the Disclosed Matters, such Borrower and its Subsidiaries have complied in all material
respects with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government or any instrumentality or agency thereof having jurisdiction over the conduct of their respective businesses or the ownership of
their respective Property, the non-compliance with which could reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 
 5.13. Ownership of Properties. Such Borrower and its Subsidiaries have good title to or rights to use (except for minor defects in title that do not interfere with their ability to conduct their
business as currently conducted or to utilize such properties for the intended purposes), free of all Liens other than those permitted by Section 6.12, all of the assets material to the business 

  
 60 

 
of such Borrower and its Subsidiaries, taken as a whole, except where the failure to have such title or right could not reasonably be expected to result in a Material Adverse Effect with respect
to such Borrower. 
 5.14. Environmental Matters. Other than the Disclosed Matters, (i) there exists no violation
of, no liability known to such Borrower, whether or not asserted, under, and no requirement under, any Environmental Laws, and (ii) as of the Closing Date, neither Borrower nor any Subsidiary has received any written notice alleging any such
violation, liability or requirement under any Environmental Laws, that, in the case of either clause (i) or clause (ii), could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect with respect to such

Subsidiaries or Non-Material Subsidiaries or an SPC) or any Substantial Portion of its Property or the Property of any of its Subsidiaries (other than a Project Finance Subsidiary or a Non-Material Subsidiary or an SPC), or a proceeding seeking an
order for relief under the Federal bankruptcy laws as now or hereafter in effect or seeking to adjudicate it a bankrupt or insolvent, or seeking dissolution, winding up, liquidation, reorganization, arrangement, adjustment or composition of it or

have been satisfied). 

 ARTICLE VIII 

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES 
 8.1. Acceleration. If any Default described in Section 7.6 or 7.7 occurs with respect to a Borrower, the obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of
Credit hereunder to such Borrower (and, if such Borrower is the Borrowing Subsidiary, the Company) shall automatically terminate and the Obligations of such Borrower (and, if such Borrower is the Borrowing Subsidiary, the Company) shall immediately
become due and payable without any election or action on the part of the Agent, any Issuing Bank or any Lender. If any other Default occurs with respect to a Borrower, the Required Lenders (or the Agent at the direction of the Required Lenders) may
terminate or suspend the obligations of the 

  
 78 

 
Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder to such Borrower, or declare the Obligations of such Borrower (and, in the case of a Default with respect to a
Borrowing Subsidiary, of the Company) to be due and payable, or both, whereupon the Obligations of such Borrower (and, in the case of a Default with respect to the Borrowing Subsidiary, of the Company) shall become immediately due and payable,
without presentment, demand, protest or notice of any kind, all of which such Borrower hereby expressly waives. 
 If, after
acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder as a result of any Default (other than any Default as described in
Section 7.6 or 7.7 with respect to such Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by
notice to such Borrower, rescind and annul such acceleration and/or termination. 
 8.2. Amendments. None of this
Agreement, any other Loan Document or any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by each Borrower, the Agent and the
Required Lenders and, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Agent and the other party or parties thereto, in each case with the consent of the Required Lenders; provided
that (i) any provision of this Agreement or any other Loan Document may be amended by an agreement in writing entered into by each Borrower and the Agent to correct any administrative or other manifest error, omission, defect or inconsistency
so long as, in each case, the Lenders shall have received at least seven Business Days’ prior written notice thereof and the Agent shall not have received, within seven Business Days of the date of such notice to the Lenders, a written notice
from the Required Lenders stating that the Required Lenders object to such amendment and (ii) no such agreement shall (A) increase the Commitment of any Lender without the written consent of such Lender, (B) reduce the principal
amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (C) except as expressly otherwise provided herein, postpone the
scheduled maturity date of any Loan or LC Disbursement or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment,
without the written consent of each Lender affected thereby, (D) change Section 11.2 in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender, (E) change any of the
provisions of this Section or the percentage set forth in the definition of the term “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any
rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender; provided that no such agreement shall amend, modify, extend or otherwise affect the rights or obligations of the Agent,
any Issuing Bank or the Swingline Lender without the prior written consent of the Agent, such Issuing Bank or the Swingline Lender, as the case may be. 
 Notwithstanding the foregoing, any provision of this Agreement may be amended by an agreement in writing entered into by the applicable Borrower, the Required Lenders and the Agent if, by the terms of
such agreement, (i) the Commitment of each Lender not consenting to the amendment provided for therein shall terminate upon the effectiveness of such amendment 

  
 79 

 
and (ii) upon the effectiveness of such amendment, each Lender not consenting to such amendment shall receive payment in full of the principal of and interest accrued on each Advance made by
it and all other amounts owing to it or accrued for its account under this Agreement. 
 8.3. Preservation of Rights. No
omission of the Lenders, the Agent or the Issuing Banks to exercise or delay in exercising any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a
Credit Extension notwithstanding the existence of a Default or Unmatured Default or the inability of a Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial
exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid
unless in writing signed by, or by the Agent with the consent of, the requisite number of Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents
or by law afforded shall be cumulative and all shall be available to the Agent, the Issuing Banks and the Lenders until all of the Obligations have been paid in full. 
 ARTICLE IX 
 GENERAL PROVISIONS 

9.1. Survival of Representations. All representations and warranties of the Borrowers contained in this Agreement shall survive
the making of the Credit Extensions herein contemplated. 
 9.2. Governmental Regulation. Anything contained in this
Agreement to the contrary notwithstanding, no Lender shall be obligated to extend credit to either Borrower in violation of any limitation or prohibition provided by any applicable statute or regulation. 

9.3. Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the
interpretation of any of the provisions of the Loan Documents. 
 9.4. Entire Agreement. The Loan Documents embody the
entire agreement and understanding among the Agent, each Issuing Bank and the Lenders, and between the Agent, each Issuing Bank and the Lenders on one hand, and the Borrowers individually on the other hand, and supersede all prior agreements and
understandings among and between such parties, as the case may be, relating to the subject matter thereof (but do not supersede (a) any provisions of the fee letters related to the credit facilities established hereby or (b) the
indemnification and reimbursement provisions of any commitment letter related to the credit facilities established hereby to the extent applicable to the Arrangers and the Initial Lenders (as such terms are defined therein) in their capacities as
such, that in each case do not by the terms of such documents terminate upon the effectiveness of this Agreement, all of which provisions shall remain in full force and effect). 

  
 80 

 9.5. Several Obligations; Benefits of this Agreement. The respective obligations of
the Lenders and the Issuing Banks hereunder are several and not joint and no Lender or Issuing Bank shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of the Agent, any
Lender or any Issuing Bank to perform any of its obligations hereunder shall not relieve the Agent, any other Lender or any Issuing Bank of any of its obligations hereunder. Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in

the Swingline Lender or any Lender in connection with the collection of the Obligations and enforcement of the Loan Documents. 

  

	 	(ii)	 Subject to paragraph (iii) below, the Borrowers hereby further agree to indemnify the Agent, each Arranger, each Issuing Bank, the Swingline
Lender, each Lender and their Related Parties against all losses, claims, damages, penalties, judgments, liabilities and expenses (including all expenses or liabilities related to or resulting from litigation or preparation therefor, whether
commenced by the Borrowers or their Affiliates or by any third party and whether or not the Agent, any Arranger, any Issuing Bank, the Swingline Lender, any Lender or any Affiliate is a party thereto, and all attorneys’ and paralegals’
fees, time charges and expenses of attorneys and paralegals of the party seeking indemnification, which attorneys and paralegals may or may not be employees of such party seeking indemnification)

  
 81 

	 	
which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed
application of the proceeds of any Loan hereunder, except to the extent that they have resulted, as determined in a final non-appealable judgment by a court of competent jurisdiction, (a) from the gross negligence or willful misconduct of the
party seeking indemnification or (b) from the material breach by the party seeking indemnification of its agreements hereunder or under the other Loan Documents (it being agreed, however, that no such breach shall be deemed to occur as a result
of any reasonable assertion in good faith by any indemnified party that any condition to any of its obligations hereunder has not been satisfied). 

  

	 	(iii)	Each amount payable under paragraph (i) or (ii) of this Section shall be an obligation of, and shall be discharged by (a) to the extent arising out of
acts, events and circumstances related to a particular Borrower, such Borrower, and (b) otherwise, both Borrowers, with each of them being severally, but not jointly, liable for its Contribution Percentage of such amount; provided that
the Company agrees that, if the Borrowing Subsidiary shall fail to pay any amount owed by it under clause (b) of this paragraph (iii) after a demand shall have been made by the Person to which such amount is owed, the Company shall
promptly pay such amount (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of the Borrowing Subsidiary under this Section).

unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the
Agent, the Arrangers, the Swingline Lender or such Issuing Bank in its capacity as such. 

  

	 	(v)	The obligations of the Borrowers under this Section 9.6 shall survive the termination of this Agreement and, as to each Borrower, the Availability Termination Date
of such Borrower.

hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders, to the extent that the Agent deems necessary. 
 9.8. Accounting. Except as provided to the contrary herein, all accounting terms used in the calculation of any financial covenant or test shall be interpreted and all accounting determinations
hereunder in the calculation of any financial covenant or test shall be made in accordance with Agreement Accounting Principles. If any changes in generally accepted 

  
 82 

 
accounting principles are hereafter required or permitted and are adopted by any Borrower or any of its Subsidiaries with the agreement of its independent certified public accountants and such
changes result in a change in the method of calculation of any of the financial covenants, tests, restrictions or standards herein or in the related definitions or terms used therein (“Accounting Changes”), the parties hereto agree,
at the request of such Borrower, the Agent or the Required Lenders, to enter into negotiations, in good faith, in order to amend such provisions in a credit neutral manner so as to reflect equitably such changes with the desired result that the
criteria for evaluating such Borrower’s and its Subsidiaries’ financial condition shall be the same after such changes as if such changes had not been made; provided, however, until such provisions are amended
in a manner reasonably satisfactory to the Company, the Agent and the Required Lenders, no Accounting Change shall be given effect in such calculations. In the event such amendment is entered into, all references in this Agreement to Agreement
Accounting Principles shall mean generally accepted accounting principles as of the date of such amendment. Notwithstanding the foregoing, all financial statements to be delivered by such Borrower pursuant to Section 6.1 shall be prepared in
accordance with generally accepted accounting principles in effect at such time (subject in the case of interim financial statements, to the absence of footnotes and year-end adjustments). Notwithstanding the foregoing, for purposes of all
accounting or financial calculations made under this Agreement and for purposes of defining and calculating Indebtedness hereunder, leases that would have been classified as operating leases in accordance with Agreement Accounting Principles as in
effect on June 30, 2010, whether entered into before or after the Closing Date, will be treated in a manner consistent with the treatment of such leases under Agreement Accounting Principles as in effect on June 30, 2010, notwithstanding
any modifications or interpretive changes in Agreement Accounting Principles that may occur thereafter. 
 9.9. Severability
of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable or invalid without affecting the remaining provisions in
that jurisdiction or the operation, enforceability or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable. 

9.10. Nonliability. The relationship between the Borrowers individually on the one hand and the Lenders, each Issuing Bank and the
Agent on the other hand shall be solely that of borrower and lender. No provision in any Loan Document, the transactions contemplated thereby, any relationships established thereby, any communications pursuant thereto or the nature of services
provided by the Lenders, each Issuing Bank and the Agent shall create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lenders, each Issuing Bank and the Agent on the one hand and the Borrowers and their
subsidiaries, Affiliates or equityholders on the other hand. None of the Agent, any Arranger, any Issuing Bank or any Lender undertakes any responsibility to the Borrowers to review or inform the Borrowers of any matter in connection with any phase
of the Borrowers’ businesses or operations. The Borrowers agree that none of the Agent, any Arranger, any Issuing Bank or any Lender shall have liability to the Borrowers (whether sounding in tort, contract or otherwise) for losses suffered by
the Borrowers in connection with, arising out of or in any way related to the transactions contemplated and the relationship established by the Loan Documents or any act, omission or event occurring in connection therewith unless it is determined in
a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from (a) the 

  
 83 

 
gross negligence or willful misconduct of the party from which recovery is sought or (b) the material breach by the party from which recovery is sought of its agreements hereunder or under
the other Loan Documents (it being agreed, however, that no such breach shall be deemed to occur as a result of any reasonable assertion in good faith by the Agent, any Arranger, any Issuing Bank or any Lender that any condition to any of its
obligations hereunder has not been satisfied). None of the Borrowers, the Agent, any Arranger, any Issuing Bank or any Lender shall have any liability for, and each of the Agent, each Arranger, each Issuing Bank, each Lender and each Borrower hereby
waives, releases and agrees not to sue for, any special, indirect, consequential or punitive damages in connection with, arising out of or in any way related to the Loan Documents or the transactions contemplated thereby; provided, that each
Borrower shall be obligated as, and subject to the limitations, provided in Section 9.6 to indemnify the Agent, each Arranger, each Issuing Bank, the Swingline Lender, each Lender and their Related Parties against any special, indirect,
consequential or punitive damages that may be awarded against them. 
 9.11. Confidentiality. Each Lender and each
Issuing Bank agrees to hold any confidential information which it may receive from either Borrower pursuant to this Agreement in confidence, except for disclosure (i) to its Affiliates and to other Borrowers, Lenders or Issuing Banks and their
respective Affiliates, for use solely in connection with the transactions contemplated hereby, (ii) to legal counsel, accountants, and other professional advisors to, and agents, officers and employees of, such Lender or Issuing Bank, in each
case which have been informed as to the confidential nature of such information, for use solely in connection with the transactions contemplated hereby, (iii) to regulatory officials having jurisdiction over it or its Affiliates, (iv) to
any Person as required by law, regulation, or legal process (provided that, to the extent legally permitted, such Lender or Issuing Bank shall provide each Borrower with notice of such required disclosure to permit the Borrowers to contest
the necessity thereof), (v) to any Person in connection with any legal proceeding arising under or in connection with this Agreement, the Loan Documents or the transactions contemplated hereby to which such Lender or Issuing Bank is a party
(provided that, to the extent legally permitted, such Lender or Issuing Bank shall provide the Borrowers with notice of such required disclosure to permit the Borrowers to contest the necessity thereof), (vi) to any assignee of or
participant in, or prospective assignee of or participant in, any of its rights or obligations under this Agreement, if and to the extent such Person has been informed as to the confidential nature of such information and has agreed to treat such
information in accordance with the terms of this Section 9.11, (vii) to such Lender’s or Issuing Bank’s direct or indirect contractual counterparties in swap agreements or credit insurance providers with respect to the credit
facilities established hereunder, or to legal counsel, accountants and other professional advisors to any of the foregoing, in each case which have been informed as to the confidential nature of such information and have agreed to treat such
information in accordance with the terms of this Section 9.11, (viii) to rating agencies if requested or required by such agencies in connection with a rating relating to this Agreement or the Advances hereunder, (ix) with the consent
of such Borrower, (x) to any other party to this Agreement, (xi) in connection with the exercise of any remedies under this Agreement or any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan
Document or the enforcement of rights hereunder or thereunder and (xii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the credit facilities established hereunder.

 9.12. Lenders Not Utilizing Plan Assets. Each Lender represents and warrants that
none of the consideration used by such Lender to make its Loans constitutes for any purpose of ERISA or Section 4975 of the Code assets of any “plan” as defined in Section 3(3) of ERISA or Section 4975 of the Code and the
rights and interests of such Lender in and under the Loan Documents shall not constitute such “plan assets” under ERISA. 
 9.13. Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U) as collateral in the extension or maintenance of the credit
provided for herein. 
 9.14. Disclosure. Each Borrower, Lender and Issuing Bank hereby acknowledges and agrees that each
Lender, each Issuing Bank and their Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrowers and their Affiliates. 

9.15. USA Patriot Act. Each Lender and each Issuing Bank hereby notifies the Borrowers that pursuant to the requirements of the
USA Patriot Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the names and addresses of the Borrowers and other information that will allow such Lender to identify the Borrowers
in accordance with its requirements. The Borrowers shall, promptly following a request by the Agent or any Lender, provide all documentation and other information that the Agent or such Lender reasonably requests in order to comply with its ongoing
obligations under applicable “know your customer” and anti-money laundering rules and regulations including the USA Patriot Act. 
 9.16. Non-Public Information. Each Lender acknowledges that all information, including requests for waivers and amendments, furnished by the Borrowers or the Agent pursuant to or in connection
with, or in the course of administering, this Agreement will be syndicate-level information, which may contain MNPI. Each Lender represents to the Borrowers and the Agent that (i) it has developed compliance procedures regarding the use of MNPI
and that it will handle MNPI in accordance with such procedures and applicable law, including Federal, state and foreign securities laws, and (ii) it has identified in its Administrative Questionnaire a credit contact who may receive
information that may contain MNPI in accordance with its compliance procedures and applicable law, including Federal, state and foreign securities laws. 
 ARTICLE X 
 THE AGENT 

10.1. Appointment; Nature of Relationship. JPMCB is hereby appointed by each of the Lenders and each of the Issuing Banks as its
contractual representative (herein referred to as the “Agent”) hereunder and under each other Loan Document, and each of the Lenders and the each of the Issuing Banks irrevocably authorizes the Agent to act as the contractual
representative of such Lender and such Issuing Bank with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this
Article X. Notwithstanding the use of the defined term 

  
 85 

 
“Agent,” it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender or any Issuing Bank by reason of this Agreement or any other
Loan Document and that the Agent is merely acting as the contractual representative of the Lenders and the Issuing Banks with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the
Lenders’ and the Issuing Banks’ contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders or the Issuing Banks, (ii) is a “representative” of the Lenders and the Issuing
Banks within the meaning of the term “secured party” as defined in the New York Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this
Agreement and the other Loan Documents. Each of the Lenders and the Issuing Banks hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender
hereby waives. 
 10.2. Powers. The Agent shall have and may exercise such powers under the Loan Documents as are
specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties or fiduciary duties to the Lenders or the Issuing Banks, or any obligation to
the Lenders or the Issuing Banks to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent. Without limiting any other power granted under any Loan Document, each Lender authorizes and
directs the Agent to vote all the interests of the Lenders as a single bloc based upon the direction of the Required Lenders as contemplated by any Loan Document. 
 10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrowers, the Lenders or any Lender or any Issuing Bank for any action
taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final, non-appealable judgment by a court of competent
jurisdiction to have arisen from (i) the gross negligence or willful misconduct of the party from which recovery is sought or (ii) the material breach by such party of its agreements hereunder or under the other Loan Documents (it being
agreed, however, that no such breach shall be deemed to occur as a result of any reasonable assertion in good faith by the Agent, any Arranger, any Issuing Bank or any Lender that any condition to any of its obligations hereunder has not been
satisfied). 
 10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers,
agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or
observance of any of the covenants or agreements of any obligor under any Loan Document, including any agreement by an obligor to furnish information directly to each Lender and each Issuing Bank; (c) the satisfaction of any condition specified
in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness
of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrowers
or any guarantor of any of the Obligations or of any of the 

  
 86 

 
Borrowers’ or any such guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders or the Issuing Banks information that is not required to be furnished
by the Borrowers to the Agent at such time, but is voluntarily furnished by the Borrowers to the Agent (either in its capacity as Agent or in its individual capacity). 
 10.5. Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with
written instructions signed by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly requires such), and such instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders and each Issuing Bank. The Lenders and each Issuing Bank hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly requires such). The Agent shall be fully justified in
failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction in writing by the Lenders pro rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action. 
 10.6. Employment of Agents and Counsel. The Agent may execute
any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders or the Issuing Banks, except as to money or securities received by it or its
authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders
and the Issuing Banks and all matters pertaining to the Agent’s duties hereunder and under any other Loan Document. 

10.7. Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit,
letter, telegram, statement, paper or document believed by it in good faith to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the
Agent, which counsel may be employees of the Agent. 
 10.8. Agent’s Reimbursement and Indemnification. The Lenders
agree to reimburse and indemnify the Agent, severally and not jointly, ratably in proportion to the their Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Aggregate Outstanding Credit Exposure)
(determined as of the date of any such request by the Agent) (i) for any amounts not reimbursed by the Borrowers for which the Agent is entitled to reimbursement by the Borrowers under the Loan Documents in its capacity as Agent, (ii) to
the extent not paid by the Borrowers, for any other expenses incurred by the Agent on behalf of the Lenders or the Issuing Banks, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents
(including for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders or Issuing Banks) and (iii) to the extent not paid by the Borrowers, for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or 

  
 87 

 
asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including
for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders or Issuing Banks), or the enforcement of any of the terms of the Loan Documents or
of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from
the gross negligence or willful misconduct of the Agent, (ii) any indemnification required pursuant to Section 3.5(d) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the
provisions thereof and (iii) the Agent shall reimburse the Lenders for any amounts the Lenders have paid to the extent such amounts are subsequently recovered from the Borrowers. The obligations of the Lenders under this Section 10.8 shall
survive payment of the Obligations, termination and expiration of the Letters of Credit and termination of this Agreement. 

10.9. Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured
Default hereunder unless the Agent has received written notice from a Lender or a Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to the Borrowers, the Lenders and the Issuing Banks. 
 10.10. Rights as a Lender. In the event the Agent is a Lender or an Issuing Bank, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its
Commitment and its Credit Extensions as any Lender or any Issuing Bank and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” or “Issuing Bank” shall, at any time when the Agent is
a Lender or an Issuing Bank, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other
transaction, in addition to those contemplated by this Agreement or any other Loan Document, with each Borrower or any of its Subsidiaries in which such Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The
Agent, in its individual capacity, is not obligated to remain a Lender. 
 10.11. Independent Credit Decision. Each
Lender and each Issuing Bank acknowledges that it has, independently and without reliance upon the Agent, any Arranger or any other Lender or any other Issuing Bank and based on the financial statements prepared by the Borrowers and such other
documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender and each Issuing Bank also acknowledges that it will, independently and without
reliance upon the Agent, any Arranger or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the
other Loan Documents. 
 10.12. Successor Agent. The Agent may resign at any time by giving written notice thereof to the
Lenders, the Issuing Banks and the Borrowers, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, 

  
 88 

 
forty-five days after the retiring Agent gives notice of its intention to resign. Upon any such resignation, the Required Lenders, with the consent of the Borrowers (which consent shall not be
unreasonably withheld or delayed; provided that such consent shall not be required in the event and continuation of a Default), shall have the right to appoint, on behalf of the Borrowers and the Lenders, a successor Agent. If no successor
Agent shall have been so appointed by the Required Lenders or consented to by the Borrowers within thirty days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the
Borrowers and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrowers or any Lender or any Issuing Bank, appoint any of its Affiliates which is a commercial bank as a
successor Agent hereunder. If the Agent has resigned and no successor Agent has been appointed, the Required Lenders may perform all the duties of the Agent hereunder and the Borrowers shall make all payments in respect of the Obligations to the
applicable Lenders and for all other purposes shall deal directly with the Lenders. If the Agent has resigned and, at such time, holds cash collateral under this Agreement, the Agent shall continue to hold such cash collateral for the benefit of the
Lenders and the applicable Issuing Bank until a successor Agent has been appointed. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Unless otherwise agreed by the Company, any
such successor Agent shall be a Lender or, if no Lender will accept such appointment, a commercial bank having capital and retained earnings of at least $1,000,000,000 (or such lower amount as shall be acceptable to the Company). Upon the acceptance
of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning Agent. Upon the effectiveness of the resignation of the
Agent, the resigning Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation of the Agent, the provisions of this Article X shall continue in effect for the benefit
of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties
and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent. 

10.13. Agent and Arrangers Fees. Each Borrower severally and not jointly agrees to pay to the Agent and each Arranger, for their
respective accounts, the agent and arrangers fees separately agreed to by such Borrowers, the Agent and such Arranger pursuant to and in accordance with those certain fee letters dated as of September 21, 2012 and as otherwise mutually agreed
to in writing from time to time. 
 10.14. Delegation to Affiliates. The Borrowers, the Lenders and the Issuing Banks
agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates (it being agreed that the Agent will remain responsible for the performance of all such duties). Any such Affiliate (and such Affiliate’s
directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX
and X. 

  
 89 

 10.15. Joint Arrangers, Joint Bookrunners, Syndication Agents and Documentation
Agents. The Persons identified in this Agreement as “Joint Arrangers”, “Joint Bookrunners”, “Syndication Agents” and “Documentation Agents”, in such capacities, shall have no right, power, obligation,
liability, responsibility or duty under this Agreement. Without limiting the foregoing, such Persons, in such capacities, shall not have or be deemed to have a fiduciary relationship with any other Person. Each Lender hereby makes the same
acknowledgements with respect to such Persons as it makes with respect to the Agent in Section 10.11. 
 ARTICLE XI

 SETOFF; RATABLE PAYMENTS 
 11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Borrower becomes insolvent or any payment Default pursuant to Section 7.2 occurs
with respect to a Borrower, or any other Default with respect to a Borrower shall occur and be continuing and the Required Lenders shall have terminated any Commitments as to such Borrower or accelerated the maturity of any Loans to such Borrower,
then any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender or any Issuing Bank
to or for the credit or account of such Borrower may be offset and applied toward the payment of the Obligations owing by such Borrower to such Lender or such Issuing Bank, whether or not the Obligations, or any part thereof, shall then be due.
Promptly upon the exercise of its right of setoff hereunder, each Lender and Issuing Bank shall deliver written notice thereof to the Agent and the Agent shall make such notice available to the other Lenders and Issuing Banks. 

11.2. Ratable Payments. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC
Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations
in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the amount of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amounts of principal of and accrued interest on their
Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded
and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms
of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to either
Borrower, any other Subsidiary or any Affiliate of any of the foregoing (as to which the provisions of this paragraph shall apply). Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that
any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in
the amount of such participation.

 ARTICLE XII 
 BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS 
 12.1. Successors and
Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), except that (i) no Borrower may assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of the Agent and each Lender (and any attempted assignment or transfer by either Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or
obligations hereunder except in accordance with this Section. 
 (b) Assignments. 

 

	 	(i)	Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more Lenders, Affiliates of Lenders, Approved Funds or other Persons,
other than, in each case, a natural person, a Borrower or a subsidiary or Affiliate of a Borrower (any such permitted assignee being called an “Eligible Assignee”) all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: 

(A) each Borrower; provided that no consent of the Borrowers shall be required (1) for an assignment to a
Lender, an Affiliate of a Lender or an Approved Fund and (2) if a Default has occurred and is continuing, for any other assignment; provided further, that each Borrower will be deemed to have consented to an assignment if it does not respond to
a written request for a consent thereto within 10 Business Days after actual receipt of such request; 
 (B) the
Agent; provided that no consent of the Agent shall be required for an assignment to a Lender or an Affiliate of a Lender; 
 (C) each Issuing Bank; and 
 (D) the Swingline Lender. 

 

	 	(ii)	Assignments shall be subject to the following additional conditions: 

(A) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the
entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of 

  
 91 

 
the date the Assignment and Assumption with respect to such assignment is delivered to the Agent) shall not be less than $5,000,000 unless each Borrower and the Agent otherwise consent;
provided that no such consent of the Borrowers shall be required if a Default has occurred and is continuing; 
 (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, except that this sentence shall not apply
to rights in respect of outstanding Competitive Loans; 
 (C) the parties to each assignment shall execute and
deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 
 (D) the assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level
information (which may contain MNPI) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable law, including Federal, State and foreign securities laws. 

 

	 	(iii)	Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and
Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all the assigning Lender’s rights and obligations under this
Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Article III and Section 9.6). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply
with this Section 12.1 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such Lender’s rights or obligations as provided in Section 12.1(c). 

 

	 	(iv)	The Agent shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and records of the names and addresses of the Lenders, and the
Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error and
the Borrowers, the Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.
The Register shall be available for inspection by either Borrower and, as to entries pertaining to it, any Issuing Bank or Lender, at any reasonable time and from time to time upon reasonable prior notice. 

  
 92 

	 	(v)	Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative
Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in this Section and any written consent to such assignment required by this Section, the Agent shall accept such Assignment
and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. Each assignee, by its execution
and delivery of an Assignment and Assumption, shall be deemed to have represented to the assigning Lender and the Agent that such assignee is an Eligible Assignee. 

(c) Participations. 
  

	 	(i)	Any Lender may, without the consent of either Borrower, the Agent, any Issuing Bank or the Swingline Lender, sell participations to one or more Eligible Assignees

obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Agent, the Issuing Banks, the Swingline
Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement or any other Loan
Document; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.2 that affects
such Participant or requires the approval of all of the Lenders. Subject to paragraph (c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Article III to the same extent as if it were a Lender
and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided such
Participant agrees to be subject to Section 11.2 as though it were a Lender. 

  

	 	(ii)	 A Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Non-U.S. Lender if it were
a Lender shall 

  
 93 

	 	
not be entitled to the benefits of Section 3.5 unless each Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to
comply with Section 3.5 as though it were a Lender. 

  

	 	(iii)	Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name
and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under any Loan Document (the “Participant Register”); provided that no
Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its
other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the
United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for
all purposes of any Loan Document notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent shall have no responsibility for maintaining a Participant Register. 

(d) Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this
Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that
no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

 RESTRICTIVE AGREEMENTS 
 (see Section 6.14) 

Ameren Illinois Company 
 Ameren Illinois Company Restated Articles of Incorporation: Dividend Restriction. So long as any shares of the Cumulative Preferred Stock are outstanding, Ameren Illinois Company shall not pay any
dividends on its Common Stock (other than dividends payable in Common Stock) or make any distribution on or purchase or otherwise acquire for value any of its Common Stock (each such payment, distribution, purchase and/or acquisition being referred
to in this paragraph as a “common stock dividend”), except to the extent permitted by the following provisions of this paragraph: 
 (a) No common stock dividend shall be declared or paid in an amount which, together with all other common stock dividends declared in the year ending on (and including) the date of the declaration of such
common stock dividend, would in the aggregate exceed 50% of the net income of Ameren Illinois Company available for dividends on its Common Stock for the twelve consecutive calendar months ending on the last day of the calendar month next preceding
the declaration of such common stock dividend, if at the end of such calendar month the ratio (referred to in this paragraph as the “capitalization ratio”) of the Common Stock Equity (as hereinafter defined) of Ameren Illinois
Company, to the total capital (as hereinafter defined) of Ameren Illinois Company shall be less than 20%. 
 (b)
If such capitalization ratio, determined as aforesaid, shall be 20% or more, but less than 25%, no common stock dividend shall be declared or paid in an amount which, together with all other common, stock dividends declared in the year ending on
(and including) the date of the declaration of such common stock dividend, would exceed 75% of the net income of Ameren Illinois Company available for dividends on its Common Stock for the twelve consecutive calendar months ending on the last day of
the calendar month next preceding the declaration of such common stock dividend. 
 (c) If such capitalization
ratio, determined as aforesaid, shall be in excess of 25%, no common stock dividend shall be declared or paid which would reduce such capitalization ratio to less than 25% except to the extent permitted by the next preceding clauses (a) and
(b) hereof. 
 “Common Stock Equity,” as that term is used in this paragraph shall consist of the sum of (1) the
capital represented by the issued and outstanding shares of Common Stock (including premiums on Common Stock) and (2) the surplus accounts of Ameren Illinois Company, less (i) any excess of the value, as recorded on Ameren Illinois
Company’s books, over the original cost, as determined or approved by the regulatory commission having jurisdiction thereof, of used and useful electric and gas utility plant and property, unless (a) such excess is being amortized or
provided for by reserves, or (b) such excess has been held, by final order of a court having jurisdiction or of the regulatory bodies having jurisdiction, to constitute an asset which need not be amortized or provided for by reserves, and
(ii) any amount by which the aggregate amount payable, on the involuntary dissolution, liquidation or winding up of Ameren Illinois Company, in respect of all outstanding shares of stock of Ameren Illinois Company having a preference as to
dividends over the Common Stock 

  
 Schedule 3
Page 1 

 
exceeds the aggregate par or stated value of such outstanding shares, unless such excess is being amortized, or provided for by reserves, and (iii) any items such as debt discount, premium
and expense, capital stock discount and expense and similar items, classified as assets on the balance sheet of Ameren Illinois Company, unless such items are being amortized, or provided for by reserves or unless and to the extent that such items
are not required to be written off or amortized by the uniform systems of accounts applicable thereto prescribed by the regulatory bodies having jurisdiction. The “total capital of Ameren Illinois Company” shall consist of the sum
of (i) the principal amount of all outstanding indebtedness of Ameren Illinois Company maturing one year or more after the date of the issue thereof and (ii) the par or stated value of all outstanding capital stock (which shall include
premiums on capital stock) of all classes of Ameren Illinois Company, and (iii) all surplus accounts of Ameren Illinois Company. The “net income of Ameren Illinois Company available for dividends on its Common Stock” for any
period shall be determined by deducting from the sum of the operating revenues and income from investments and other miscellaneous income for such period, all operating expenses for such period, including maintenance and provision for depreciation
as recorded on the books of Ameren Illinois Company (but not less than an amount equal to 15% of the gross operating revenues of Ameren Illinois Company less the cost of electric energy and gas purchased for resale, during such period), income and
excess profits and other taxes, all proper accruals, interest charges, amortization charges, other proper income deductions and an amount equal to the dividend requirements for such period on all outstanding shares of stock of Ameren Illinois
Company having a preference as to dividends over the Common Stock, all as shall be determined in accordance with such systems of accounts as may be prescribed by regulatory authorities having jurisdiction in the premises or, in the absence thereof,
in accordance with sound accounting practices. All indebtedness and capital stock of Ameren Illinois Company owned by Ameren Illinois Company shall be excluded in determining total capital. Purchases or other acquisitions of Common Stock shall be
deemed, for the purposes of this paragraph, to constitute a common stock dividend declared as of the date on which such purchases or acquisitions are consummated. 
 Genco 
 Genco Indenture dated November 1, 2000, as supplemented:
Restricted/Conditional Payments. So long as any senior notes are outstanding, if Genco’s Senior Debt Service Coverage Ratio calculated on a Pro-Forma Basis (both as defined in Article I of this indenture) is below 1.75 to 1.0 for the most
recently ended four fiscal quarters prior to the date of measurement or, based on projections prepared by Genco, below 1.75 to 1.0 (or 1.50 to 1.0 under circumstances described in Section 3.11(b) of this indenture) for any of the succeeding
four six-month periods from the month including the date of measurement, Genco may not (i) pay dividends on or redeem or repurchase its capital stock or (ii) make payments of principal or interest on any subordinated indebtedness Genco has
issued unless any such redemption or repurchase of capital stock or subordinated indebtedness is paid from proceeds received from the concurrent issuance of capital stock or other subordinated indebtedness. There are no restrictions or conditions in
the Indenture limiting Genco’s ability to make repayments of borrowings under, or investments in, the Company’s Non-utility Money Pool Agreement.

 DISCLOSED MATTERS 
 (See Section 1.1) 

Illinois Energy Infrastructure Modernization Act (“IEIMA”) 

On January 3, 2012, Ameren Illinois Company elected to participate in the performance-based formula ratemaking process established
pursuant to the IEIMA by filing initial performance-based formula rates with the Illinois Commerce Commission (the “ICC”). The initial filing was based on 2010 recoverable costs and expected net plant additions for 2011 and 2012. In
September 2012, the ICC issued an order approving an Ameren Illinois Company electric delivery service revenue requirement of $779 million, which is a $55 million decrease from the electric delivery service revenue requirement allowed in the
pre-IEIMA 2010 electric delivery service rate order. The rates became effective on October 19, 2012, and will be effective through the end of 2012. Ameren Illinois Company requested a rehearing of the initial filing order, which the ICC denied.
In October 2012, Ameren Illinois Company filed an appeal of the ICC order to the Appellate Court of the Fourth District of Illinois. A decision by the appellate court is expected in 2013. Ameren Illinois Company believes that the ICC misapplied
Illinois law, through including the use of an average rate base as opposed to a year-end rate base, the treatment of accumulated deferred income taxes, the method for calculating the equity portion of Ameren Illinois Company’s capital
structure, and the method for calculating interest on the revenue requirement reconciliation. 
 The ICC’s September 2012
order jeopardizes Ameren Illinois Company’s ongoing ability to implement infrastructure improvements to the extent and on the timetable envisioned in the IEIMA. Until the uncertainty surrounding how the Illinois law will ultimately be
implemented is removed, Ameren Illinois Company is reducing its IEIMA capital spending with a corresponding negative effect on the job creation that the legislature sought to achieve with the law. Ameren Illinois Company expects to reduce or defer a
total of $30 million of its previously planned 2013 electric distribution capital expenditures. 
 On April 20, 2012,
Ameren Illinois Company filed a request with the ICC to update its annual electric delivery service revenue requirement based on 2011 recoverable costs and expected net plant additions for 2012. The update filing will result in new electric delivery
service rates on January 1, 2013. The update filing, as amended in September 2012, requested an annual revenue requirement of $796 million, which would result in an annual increase of $17 million in Ameren Illinois Company’s revenues for
electric delivery service above the amount allowed in the ICC initial filing order. The requested increase primarily reflects higher recoverable operating expenses, higher taxes, and a higher equity portion of the capital structure offset by a lower
return on equity due to decreases in the average 30-year United States treasury bond rates. In September 2012, the ICC staff recommended a $765 million electric delivery service revenue requirement, which is $14 million below the amount allowed in
the ICC initial filing order. Other parties also made recommendations through testimony filed in Ameren Illinois Company’s update filing. On November 7, 2012, the administrative law judges issued a proposed order that reflected an annual
revenue requirement of $764 million, which would result in an annual decrease of $15 million in Ameren Illinois Company’s revenues for electric delivery service below the amount allowed in the ICC initial filing order. 

  
 Schedule 6
Page 1 

 The IEIMA provides for an annual reconciliation of the revenue requirement necessary to
reflect the actual costs incurred in a given year with the revenue requirement that was in effect for that year. Consequently, Ameren Illinois Company’s 2012 electric delivery service revenues will be based on its 2012 actual recoverable costs,
rate base, and return on common equity as calculated under the IEIMA’s performance-based formula ratemaking framework. The 2012 revenue requirement under the IEIMA’s formula ratemaking framework is expected to be lower than the revenue
requirement included in both the ICC’s 2010 electric rate order and the ICC’s September 2012 order related to Ameren Illinois Company’s initial IEIMA filing. As a result, Ameren Illinois Company recorded a regulatory liability to
represent its estimate of the probable decrease in electric delivery service rates expected to be approved by the ICC to provide Ameren Illinois Company recovery of all prudently and reasonably incurred costs and an earned rate of return on common
equity for 2012. Ameren Illinois Company’s actual return on equity relating to electric delivery service cannot exceed 50 basis points above or below its allowed return. During the third quarter of 2012, Ameren Illinois Company’s electric
delivery service return on equity was capped at the maximum allowed return on equity based on the IEIMA formula ratemaking framework. As of September 30, 2012, Ameren Illinois Company recorded a cumulative regulatory liability of $35 million
with a corresponding decrease in electric revenues for electric delivery service relating to the 2012 revenue requirement reconciliation and the return on equity collar, which will be refunded to customers during 2014 with interest pursuant to the
provisions of the IEIMA. 
 The IEIMA requires Ameren Illinois Company to obtain ICC approval of its advanced metering
infrastructure deployment plan. The advanced metering infrastructure deployment plan outlines how Ameren Illinois Company will comply with the IEIMA requirement to spend $360 million on smart grid assets over ten years on a cost-beneficial basis to
its electric customers. In March 2012, Ameren Illinois Company submitted its advanced metering infrastructure deployment plan to the ICC, and the ICC subsequently denied that plan in May 2012. The ICC ruled that Ameren Illinois Company’s plan
did not provide enough support to prove that it was cost beneficial for electric customers. Ameren Illinois Company requested and received a rehearing from the ICC. In its rehearing request, Ameren Illinois Company submitted a modified advance
metering infrastructure deployment plan designed to address the ICC’s concerns about the cost justification of the plan. Ameren Illinois Company expects the ICC will issue an order later this year. If approved, the plan targets the second
quarter of 2014 to begin installation of smart meters. If an advanced metering infrastructure deployment plan is ultimately not approved by the ICC, Ameren Illinois Company may be precluded from using the IEIMA’s performance-based formula
rates.

 November 14, 2012 
 To the Lenders and 

JPMorgan Chase Bank, N.A., as Agent 
 383 Madison
Avenue 
 New York, NY 10179 
 Dear
Ladies and Gentlemen: 
 I, Gregory L. Nelson, am the Senior Vice President, General Counsel and Secretary of Ameren Corporation,
a Missouri corporation (the “Company”), and certain of its subsidiaries. I, or lawyers under my direction, have acted as counsel for the Company in connection with the negotiation and execution of that certain Credit Agreement dated
as of November 14, 2012 (the “Credit Agreement”), among the Company, Ameren Illinois Company, an Illinois corporation (“Ameren Illinois” and, together with the Company, the “Borrowers” and each
a “Borrower”), the lenders from time to time party thereto (the “Lenders”) and JPMorgan Chase Bank, N.A., as Agent. Capitalized terms used and not otherwise defined herein have the meanings assigned to such terms in
the Credit Agreement. 
 In rendering the opinion expressed below, I, or lawyers under my direction, have examined originals or
copies, certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or
advisable for purposes of this opinion. 
 In making the examinations described above, I have assumed without independent
investigation the capacity of natural persons (other than the office held by each representative of the Company) as reflected adjacent to such individual’s signature on the Credit Agreement and the Notes (each a “Loan Document”
and collectively, the “Loan Documents”), the genuineness of all signatures (other than those of representatives of the Company appearing on the Loan Documents), the authenticity of all documents furnished to me as originals, the
conformity to originals of all documents furnished to me as certified or photostatic copies and the authenticity of the originals of such documents. In addition, I have assumed without independent investigation that (i) the Loan Documents have
been duly authorized, executed and delivered by the parties thereto other than the Company, and constitute their valid, lawful and binding obligations and agreements, and (ii) there is no separate agreement, undertaking, or course of dealing
modifying, varying or waiving any of the terms of the Loan Documents. As to matters of fact not independently established by me relevant to the opinions set forth herein, I have relied without independent investigation on the representations
contained in the Loan Documents and in certificates of public officials and responsible representatives of the Company furnished to me; provided, however, that I advise that in the course of my representation of the Company, I have
obtained no information that leads me to believe that any such representation or certificate is untrue or misleading in any material respect. 

 Upon the basis of and subject to the foregoing, I am of the opinion that: 

1. The Company is a corporation, duly and properly incorporated, validly existing and in good standing under the laws of the State of
Missouri and has all requisite authority to conduct its business as presently conducted in each jurisdiction in which its business is conducted, other than the failure of the Company to be qualified to transact business in any such jurisdiction to
the extent such failure could not reasonably be expected to result in a Material Adverse Effect. 
 2. The Company has the power
and authority and legal right to execute and deliver, and to perform its obligations under, the Loan Documents. The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Loan Documents have been
duly authorized by proper proceedings, and the Loan Documents to which the Company is a party constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforceability
may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a
proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing. 
 3. Neither the
execution and delivery by the Company of the Loan Documents, nor the consummation of the transactions contemplated therein, nor the performance by the Company of its obligations thereunder, (x) violate (i) any law, rule or regulation of
the State of Missouri or the United States of America, or any order, writ, judgment, injunction, decree or award binding on the Company, (ii) the Company’s articles of incorporation or by-laws, or (iii) the provisions of any
indenture, material instrument or material agreement to which the Company or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or (y) conflict with, or constitute a default under, or result in, or
require, the creation or imposition of any Lien in, of or on the Property of the Company pursuant to the terms of, any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or
filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Company, is required to be obtained by the Company in
connection with the execution and delivery of the Loan Documents, the borrowings and issuances of Letters of Credit for the account of the Company under the Loan Documents, the payment and performance by the Company of the obligations thereunder or
the legality, validity, binding effect or enforceability as to the Company of any of the Loan Documents. 
 4. Except for the
Disclosed Matters, there is no litigation, arbitration, governmental investigation, proceeding or inquiry currently existing, or, to the best of my knowledge after due inquiry, pending or threatened against or affecting the Borrowers or any of their
Subsidiaries, which, if determined adversely to such Borrower or any of its Subsidiaries, could reasonably be expected to have a Material Adverse Effect with respect to such Borrower or which seeks to prevent, enjoin or delay the making of the Loans
or would adversely effect the legality, validity or enforceability of the Loan Documents as to such Borrower or the ability of such Borrower to perform the transactions contemplated therein. 

  
 2 

 5. No Borrower is an “investment company” or a company “controlled” by
an “investment company,” within the meaning of the Investment Company Act of 1940, as amended. 
 6. The Company is a
“holding company” and Ameren Illinois is a “public utility,” as such terms are defined in the Public Utility Holding Company Act of 2005. The FERC, in accordance with Section 204 of the Federal Power Act, has
issued a FERC Order dated September 20, 2012, with respect to Ameren Illinois, which is in full force and effect, authorizing the incurrence of short-term indebtedness by Ameren Illinois in an aggregate principal amount outstanding not to
exceed $1 billion. The authorization under the September 20, 2012 FERC Order expires September 30, 2014 and, unless such authorization is no longer required by applicable laws and regulations, additional authorization from the FERC (or any
governmental agency that succeeds to the authority of the FERC) or the Illinois Commerce Commission will be necessary for Ameren Illinois to obtain any Advances under the Credit Agreement or to incur or issue short-term indebtedness, including
Advances extended under the Credit Agreement, after September 30, 2014. No regulatory authorizations, approvals, consents, registrations, declarations or filings are required in connection with the borrowings by, and issuances of Letters of
Credit for the account of, the Borrowers under the Credit Agreement or the performance by each Borrower of its Obligations under the Credit Agreement and under the other Loan Documents, except as set forth above or where the failure to have
obtained, made or maintained any such authorizations, approvals, consents, registrations, declarations or filings could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 

7. In a properly presented case, a Missouri court or a federal court applying Missouri choice of law rules should give effect to the
choice of law provisions of the Loan Documents and should hold that the Loan Documents are to be governed by the laws of the State of New York rather than the laws of the State of Missouri. In rendering the foregoing opinion, I note that by their
terms the Loan Documents expressly select New York law as the law governing their interpretation. The choice of law provisions of the Loan Documents are not voidable under the laws of the State of Missouri. Notwithstanding the foregoing, even
if a Missouri court or a federal court holds that the Loan Documents are to be governed by the laws of the State of Missouri, the Loan Documents would constitute legal, valid and binding obligations of the Company, enforceable against the Company
under Missouri law (including usury provisions) in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the
enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing. 

I express no opinion as to the compliance or noncompliance, or the effect of the compliance or noncompliance, of any addressee with any
state or federal laws or regulations applicable to it by reason of its status as or affiliation with a federally insured depository institution. 
 I am a member of the Bar of the State of Missouri and the foregoing opinion is limited to the laws of the State of Missouri and the Federal laws of the United States of America typically relevant to a
transaction of this type. I note that the Loan Documents are governed by the laws of the State of New York and, for purposes of the opinion expressed in opinion paragraph 2 above and with 

  
 3 

 
your permission, I have assumed that the laws of the State of New York do not differ from the laws of the State of Missouri in any manner that would render such opinion incorrect. This opinion is
rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without my prior written consent.
Notwithstanding anything in this opinion letter to the contrary, you may disclose this opinion (i) to prospective successors and assigns of the addressees hereof, (ii) to regulatory authorities having jurisdiction over any of the
addressees hereof or their successors and assigns, and (iii) pursuant to valid legal process, in each case without my prior consent.

To the Lenders and 
 JPMorgan Chase Bank, N.A.,
as Agent 
 383 Madison Avenue 
 New
York, NY 10179 
 Dear Ladies and Gentlemen: 
 I, Craig W. Stensland, am Managing Assistant General Counsel of Ameren Services Company, a subsidiary of Ameren Corporation, a Missouri corporation (the “Company”) and an affiliate of
Ameren Illinois Company, an Illinois corporation (“Ameren Illinois” and, together with the Company, the “Borrowers”) which provides legal and other professional services to Ameren Illinois. I, or lawyers under my
direction, have acted as counsel for Ameren Illinois in connection with the Credit Agreement dated as of November 14, 2012 (the “Credit Agreement”), among the Company, Ameren Illinois, the lenders from time to time party
thereto (the “Lenders”) and JPMorgan Chase Bank, N.A., as Agent. Capitalized terms used and not otherwise defined herein have the meanings assigned to such terms in the Credit Agreement. 

In rendering the opinion expressed below, I, or lawyers under my direction, have examined originals or copies, certified or otherwise identified to my
satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or advisable for purposes of this opinion. 

In making the examinations described above, I have assumed without independent investigation the capacity of natural persons (other than the office held
by each representative of Ameren Illinois) as reflected adjacent to such individual’s signature on the Credit Agreement and the Notes (each a “Loan Document” and collectively, the “Loan Documents”), the
genuineness of all signatures (other than those of representatives of Ameren Illinois appearing on the Loan Documents), the authenticity of all documents furnished to me as originals, the conformity to originals of all documents furnished to me as
certified or photostatic copies and the authenticity of the originals of such documents. In addition, I have assumed without independent investigation that (i) the Loan Documents have been duly authorized, executed and delivered by the parties
thereto other than Ameren Illinois, and constitute their valid, lawful and binding obligations and agreements, and (ii) there is no separate agreement, undertaking, or course of dealing modifying, varying or waiving any of the terms of the Loan
Documents. As to 

 EXHIBIT A-2 

 

 
matters of fact not independently established by me relevant to the opinions set forth herein, I have relied without independent investigation on the representations contained in the Loan
Documents and in certificates of public officials and responsible representatives of Ameren Illinois furnished to me; provided, however, that I advise that in the course of my representation of Ameren Illinois, I have obtained no
information that leads me to believe that any such representation or certificate is untrue or misleading in any material respect. 
 Upon the
basis of and subject to the foregoing, I am of the opinion that: 
  

	1.	Ameren Illinois is a corporation, duly and properly incorporated, validly existing and in good standing under the laws of the State of Illinois and has all requisite
authority to conduct its business as presently conducted in each jurisdiction in which its business is conducted, other than the failure of Ameren Illinois to be qualified to transact business in any such jurisdiction to the extent such failure
could not reasonably be expected to result in a Material Adverse Effect. 

  

	2.	Ameren Illinois has the power and authority and legal right to execute and deliver, and to perform its obligations under, the Loan Documents. The execution and delivery
by Ameren Illinois of, and the performance by Ameren Illinois of its obligations under, the Loan Documents have been duly authorized by proper proceedings, and the Loan Documents to which Ameren Illinois is a party constitute legal, valid and
binding obligations of Ameren Illinois, enforceable against Ameren Illinois in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating
to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing.

  

	3.	Neither the execution and delivery by Ameren Illinois of the Loan Documents, nor the consummation of the transactions contemplated therein, nor the performance by
Ameren Illinois of its obligations thereunder, (x) violate (i) any law, rule or regulation of the State of Illinois or the United States of America, or any order, writ, judgment, injunction, decree or award binding on Ameren Illinois,
(ii) Ameren Illinois’ articles of incorporation or by-laws, or (iii) the provisions of any indenture, material instrument or material agreement to which Ameren Illinois or its Subsidiaries, if any, is a party or is subject, or by
which it, or its Property, is bound, or (y) conflict with, or constitute a default under, or result in, or require, the creation or imposition of any Lien in, of or on the Property of Ameren Illinois pursuant to the terms of, any such
indenture, instrument or agreement. 

 EXHIBIT A-2 

 

	4.	Ameren Illinois is a “public utility” as defined in the Illinois Public Utilities Act. The FERC, in accordance with Section 204 of the Federal Power Act,
has issued a FERC Order dated September 20, 2012, with respect to Ameren Illinois, authorizing the incurrence of short-term indebtedness by Ameren Illinois in an aggregate principal amount outstanding not to exceed $1 billion. The authorization
under the September 20, 2012 FERC Order expires September 30, 2014 and, unless such authorization is no longer required by applicable laws and regulations, additional authorization from the FERC (or any governmental agency that succeeds to
the authority of the FERC) or the Illinois Commerce Commission will be necessary for Ameren Illinois to obtain any Advances under the Credit Agreement or to incur or issue short-term indebtedness, including Advances extended under the Credit
Agreement, after September 30, 2014. No regulatory authorizations, approvals, consents, registrations, declarations or filings are required in connection with the borrowings by, and issuances of Letters of Credit for the account of, Ameren
Illinois under the Credit Agreement or the performance by Ameren Illinois of its Obligations under the Credit Agreement and under the other Loan Documents, except as set forth above or where the failure to have obtained, made or maintained any such
authorizations, approvals, consents, registrations, declarations or filings could not reasonably be expected to result in a Material Adverse Effect with respect to Ameren Illinois. 

 

	5.	In a properly presented case, an Illinois court or a federal court applying Illinois choice of law rules should give effect to the choice of law provisions of the Loan
Documents and should hold that the Loan Documents are to be governed by the laws of the State of New York rather than the laws of the State of Illinois. In rendering the foregoing opinion, I note that by their terms the Loan Documents expressly
select New York law as the law governing their interpretation. The choice of law provisions of the Loan Documents are not voidable under the laws of the State of Illinois. Notwithstanding the foregoing, even if an Illinois court or a federal
court holds that the Loan Documents are to be governed by the laws of the State of Illinois, the Loan Documents would constitute legal, valid and binding obligations of Ameren Illinois, enforceable under Illinois law (including usury provisions)
against Ameren Illinois in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’
rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing. 

I express no opinion as to the compliance or noncompliance, or the effect of the compliance or noncompliance, of any addressee with any state or federal
laws or regulations applicable to it by reason of its status as or affiliation with a federally insured depository institution. 

 EXHIBIT A-2 

 

 I am a member of the Bar of the State of Illinois and the foregoing opinion is limited to the laws of
the State of Illinois and the Federal laws of the United States of America. I note that the Loan Documents are governed by the laws of the State of New York and, for purposes of the opinion expressed in opinion paragraph 2 above and with your
permission, I have assumed that the laws of the State of New York do not differ from the laws of the State of Illinois in any manner that would render such opinion incorrect. This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without my prior written consent. Notwithstanding anything in this opinion letter to the
contrary, you may disclose this opinion (i) to prospective successors and assigns of the addressees hereof, (ii) to regulatory authorities having jurisdiction over any of the addressees hereof or their successors and assigns, and
(iii) pursuant to valid legal process, in each case without my prior consent.

 SUBORDINATION TERMS 
 All subordinated indebtedness (hereinafter referred to as
“Subordinated Debt”) of any Borrower incurred after the date of this Agreement that is not being included in the calculation of Consolidated Indebtedness pursuant to subclause (i)(B)(x) of the proviso in Section 6.15 shall be
in the form of indebtedness of such Borrower to the Company or any of its Subsidiaries that is subordinate and junior to any and all indebtedness (hereinafter referred to as “Senior Debt”) of such Borrower, whether existing on the
date of this Agreement or thereafter incurred, in respect of (i) all Obligations of such Borrower under this Agreement, including Obligations in respect of Letters of Credit, (ii) other borrowings of such Borrower from any one or more
banks, insurance companies, pension or profit sharing trusts or other financial institutions whether secured or unsecured and (iii) all other borrowings incurred, assumed or guaranteed by such Borrower, at any time, evidenced by a note,
debenture, bond or other similar instrument (including capitalized lease and purchase money obligations, and/or for the acquisition (whether by way of purchase, merger or otherwise) of any business, real property or other assets (except assets
acquired in the ordinary course of business) but excluding obligations other than for borrowed money including trade payables and other obligations to general creditors) other than indebtedness which, by its terms or the terms of the instrument
creating or evidencing it, provides that such indebtedness is subordinated to all other indebtedness of such Borrower. Notwithstanding any other provision of this Agreement or this Exhibit F, “Senior Debt” shall include refinancings,
renewals, amendments, extensions or refundings of the indebtedness described in clauses (i) through (iii) above. 

“Subordinate and junior” as used herein shall mean that in the event of: 

(a) any default in, or violation of, the terms or covenants of any Senior Debt, including any default in payment of
principal of, or premium, if any, or interest on, any Senior Debt whenever due (whether by acceleration of maturity or otherwise), and during the continuance thereof, or 

(b) the institution of any liquidation, dissolution, bankruptcy, insolvency, reorganization or similar proceeding relating
to any Borrower, its property or its creditors as such, 
 the obligee of indebtedness so described shall not be entitled to receive any payment
of principal of, or premium, if any, or interest on, such indebtedness until all amounts owing in respect of Senior Debt (matured and unmatured) shall have been paid in full; and from and after the happening of any event described in clause
(b) of this paragraph, all payments and distributions of any kind or character (whether in cash, securities or property) which, except for the subordination provisions hereof, would have been payable or distributable to the obligee of such
indebtedness (whether directly or by reason of being superior to any other indebtedness), shall be made to and for the benefit of the holders of Senior Debt (who shall be entitled to make all necessary claims therefor) in accordance with the
priorities of payment thereof until all Senior Debt (matured and unmatured) shall have been paid in full. No act or failure to act on the part of any Borrower, and no default under or breach of any agreement of such Borrower, whether or not herein
set forth, shall in any way prevent or limit the holder of any Senior Debt from 

 
enforcing fully the subordination terms herein provided for, irrespective of any knowledge or notice which such holder may at any time have or be charged with. In the event that any payment or
distribution is made with respect to Subordinated Debt in violation of the terms of this Exhibit F or any outstanding Senior Debt, any holder of Subordinated Debt receiving such payment or distribution shall hold it in trust for the benefit of,
