to the Company, upon its request, Letters of Credit for the Company’s own account or jointly for its own account and the account of any of its subsidiaries, other than the Borrowing Subsidiary and Ameren Illinois and their 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, and shall constitute, 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 2.6(b) 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 transmit by facsimile (or transmit 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

  
 27 

 
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 $250,000,000. Notwithstanding the foregoing, no Issuing Bank shall be required to (A) issue, amend, renew or extend any Letter of Credit (w) other
than in Dollars, (x) if 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) if 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 Restatement Effective 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 Restatement Effective 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) if, for Letters of Credit to be issued jointly for the account of either Borrower and
any of its subsidiaries in accordance with Section 2.4(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, (B) issue any Letter of Credit that is a commercial letter of credit (as opposed to a standby letter of credit) if such Issuing Bank
shall have advised the applicable Borrower that it is unable or not approved to do so, or (C) in the case of any Letter of Credit containing an automatic renewal provision, permit the extension of such Letter of Credit if (x) such Issuing Bank would
have no obligation, at such time, to issue such Letter of Credit under the terms hereof and (y) the Issuing Bank gives notice of the non-renewal thereof to the applicable Borrower and the beneficiary prior to the last date on which, under and
pursuant to the terms of such Letter of Credit, such notice will be effective to prevent such renewal. 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 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 

  
 28 

 
(ii) the date that is five Business Days prior to the earlier of the Maturity Date 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 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
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 and the LC Commitment Termination Date for such Issuing Bank, in which case the
applicable Borrower shall deposit, on or prior to the date that is 90 days prior to the earlier of the Maturity Date 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 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 of which 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 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 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 time), on (i) the Business Day on which such Borrower receives such notice, if such notice is received prior to 10:00 a.m. (New York time) on the day of

  
 29 

 
receipt, or (ii) the Business Day immediately following the day on which 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 that such payment be financed with a Floating Rate Advance
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. 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 2.9 with respect to Loans made by such Lender (and Section 2.9 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 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 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 

  
 30 

 
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 facsimile) 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 on which such LC Disbursement is made to but excluding the date on which 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 2.12 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 

  
 31 

 
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 Maturity 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 Maturity Date, at which time the Borrowers shall pay any unpaid fees accrued for the account of the terminated Issuing Bank pursuant to Section
2.6(b). 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. 

  
 32 

 (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. 
 2.5. 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 2.9 and 2.10. 

2.6. Facility Fee; Letter of Credit Fees; Reductions in Aggregate Commitment and Borrower Sublimits.

(a) Facility Fee. Subject to Section 2.22, 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 Restatement Effective Date to and including the Availability Termination Date for such Borrower, payable quarterly in arrears on each Payment Date, commencing on the first Payment Date to occur after the Restatement
Effective Date; 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. 
 (b) 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  

  
 33 

 
Participation Fee”), which shall accrue at a per annum rate equal to such Borrower’s 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 Restatement Effective 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 Restatement Effective 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 Restatement Effective 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. 
 (c) Termination of and Reductions in Aggregate Commitment and Borrower Sublimits. The
Commitments will automatically terminate on the Maturity Date. The Company (on behalf of itself and the Borrowing Subsidiary) may permanently reduce (subject to its right pursuant to Section 2.23 to subsequently increase) the Aggregate
Commitment (with or without reducing either Borrower’s 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 Business Days’ written notice to the Agent, which notice shall specify,
as applicable, (i) the aggregate amount of any such reduction and/or (ii) the individual amount by which the applicable Borrower Sublimit shall be reduced; provided, however, that (A) the amount of the Aggregate
Commitment may not be reduced below the Aggregate Outstanding Credit Exposure and (B) the Borrower Sublimit of either Borrower may not be reduced below the Borrower Credit Exposure of such Borrower, in each case, giving effect to any prepayment to
be made on such date. Any reduction of the Aggregate Commitment under this paragraph (other than the first sentence hereof) shall reduce ratably the Commitments of all the Lenders. 

2.7. 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 

  
 34 

 
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. 
 2.8. 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 $5,000,000 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 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 $5,000,000 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 Business Days’ prior notice to the Agent. Any optional payment of Advances
under this Section shall be applied ratably to the Advances of all the Lenders. Failure to make any optional payment of Advances under this Section on the date specified by the applicable Borrower to the Agent shall not constitute a Default.

 2.9. 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 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
1:00 p.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 to each Lender of each request for borrowing under this Section 2.9 by 2:00 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 3:00 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.

  
 35 

 2.10. 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 2.10 or are
repaid in accordance with Section 2.8. 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 one month (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 2.8 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 2.7, 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 2.10, 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 1:00 p.m. (New York time) at least three 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. 

2.11. 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 2.10, as applicable, 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 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 excluding) the earlier of the last day of such Interest Period or the date it is paid in accordance with Section
2.8, 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 2.9 and 2.10 and otherwise in accordance with the terms
hereof. 

  
 36 

 2.12. 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 2.11 or (ii) in the case of any other amount, 2% per annum plus the rate applicable to Floating Rate Advances as provided in Section 2.11. 

2.13. 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 JPMorgan for each payment of principal, interest and fees owed by such Borrower as such
payment becomes due hereunder. 
 2.14. Noteless Agreement; Evidence of Indebtedness. 

(a) 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. 

(b) The Agent shall also maintain accounts in which it will record (i) 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, (ii) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder,
(iii) 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, (iv) the amount of any sum received by the Agent hereunder from each Borrower and each
Lender’s share thereof and (v) all other appropriate debits and credits as provided in this Agreement, including all fees, charges, expenses and interest. 

(c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) 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. 
 (d) Any Lender may request that its
Loans be evidenced by a promissory note in substantially the form of Exhibit D (a “Note”). In such event, the applicable Borrower shall prepare, execute and deliver to such Lender such Note payable to 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 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 (a) and (b) above. 

  
 37 

 2.15. Telephonic Notices. Each Borrower hereby authorizes the Lenders and the Agent
to extend, convert or continue Advances, effect selections of Types of Advances and 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.

 2.16. 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 Restatement Effective Date, on any date on which such Floating Rate Advance is prepaid, whether by 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 such 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 on Eurodollar Advances and fees hereunder shall be calculated for actual days
elapsed on the basis of a 360-day year. Interest on Floating Rate Advances, at times when the Floating Rate Advances are based on the Prime Rate, shall be calculated for actual days elapsed on the basis of a 365/366-day year, and in each other
case shall be payable for the actual number of days elapsed on the basis of a 360-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. 

2.17. 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 

  
 38 

 
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. 

2.18. 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. 
 2.19. 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 2.4(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. 
 2.20. 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), (c), (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 Declining Lender, 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 

  
 39 

 
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 and each Issuing
Bank (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 (or the applicable portion thereof) 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
2.8. 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, in each case, giving effect to all prepayments
of the Obligations to be made in connection therewith. 
 2.21. Extension of Maturity 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 90 days (or such
shorter or longer period, respectively, as may otherwise be agreed to by the Agent and the Company), before any anniversary of the Restatement Effective Date, request that the Lenders extend the then effective Maturity Date (the “Existing
Maturity 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 Maturity Date extension request, then the Maturity Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Existing Maturity
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 

  
 40 

 
Commitment of any Declining Lender shall terminate on the Existing Maturity 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 (in each case, solely with respect to such Declining Lenders and no other Lenders) be due and payable on the Existing Maturity
Date, and on the Existing Maturity 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 Maturity 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 the “Credit Extension Date” therein shall be deemed to refer to such effective date and (B) all references to the
“Restatement Effective Date” in (x) Section 4.2.2 as it relates to Sections 5.5, 5.7 and 5.12(ii) and (y) in Sections 5.5, 5.7 and 5.12(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. Notwithstanding any other provision of this Agreement, no Issuing Bank shall have any obligation to issue any Letter of Credit expiring after the Existing Maturity
Date, or to amend, renew or extend any Letter of Credit such that it would expire after the Existing Maturity Date, unless such Issuing Bank shall have consented to the applicable Maturity Date extension (such consent to be deemed given if such
Issuing Bank is a Consenting Lender). 
 2.22. 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 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 LC Exposure does not exceed the total of all non-Defaulting Lenders’
Commitments. 

  
 41 

	 	(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 2.6(b) shall be adjusted in accordance with such
reallocation. 

  

	 	(v)	If (or to the extent that) 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 (and until and for so
long as such condition shall exist), 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 2.4(i) for so long as such
unreallocated LC Exposure is outstanding or as otherwise provided pursuant to Section 2.22(c) below. 

  

	 	(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
2.6(b) 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 2.22. 

 (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) 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, such Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless such Issuing Bank shall have entered into arrangements with the applicable Borrower or such Lender
reasonably satisfactory to such Issuing Bank 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 and each Issuing Bank shall agree that a Defaulting Lender has adequately remedied all
matters that caused such Lender to be a Defaulting Lender, then the 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 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, and all cash collateral then being held pursuant to
Section 2.22(a)(v) above in connection with the LC Exposure of such Defaulting Lender shall be released and returned to the applicable Borrower. 

  
 42 

 (d) Except as expressly provided in this Section 2.22 in connection with the obligations of
the Issuing Banks, the obligation of each Lender and Issuing Bank 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 2.22 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. 
 2.23.
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 2.23(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 and each Issuing Bank (which approval
shall not be unreasonably withheld or delayed) and shall not be subject to the approval of any other Lenders, and the Borrowers 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 Letters of Credit held by each Lender (including each such Augmenting Lender) will (subject to Section 2.22) 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 

  
 43 

 
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 2.23 shall become effective on the date specified in the
notice delivered by the Borrowers pursuant to the first sentence of paragraph (a) above or on such other date as agreed upon by the Borrowers, 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 “Restatement Effective Date” in Sections 5.5, 5.7 and 5.12(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 2.23 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: 

(a) 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 

(b) 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 

  
 44 

 (c) imposes 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 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 (and otherwise subject to the terms of Section 3.6), 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 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 and liquidity), then, within 15
days after the submission of the written statement required by Section 3.6 by such Lender or Issuing Bank (and otherwise subject to the terms of Section 3.6), 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 facsimile 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 

  
 45 

 
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 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 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 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 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 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 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 2.20 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

  
 46 

 
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 (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. 

  
 47 

	 	(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 or IRS Form W-8BEN-E 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 or IRS Form W-8BEN-E 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 IRS Form W-8BEN-E; 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 or IRS Form W-8BEN-E, 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; 

  
 48 

 (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 

  
 49 

 
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. 
 (i) For purposes of determining withholding Taxes imposed
under FATCA, from and after the Restatement Effective Date, the Borrowers and the Agent shall treat (and the Lenders hereby authorize the Agent to treat) the Agreement as not qualifying as a “grandfathered obligation” within the meaning of
Treasury Regulation Section 1.1471-2(b)(2)(i). 
 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 15 days (or, in the case of
Section 3.5, 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 

  
 50 

 
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 2.20 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 such Subsidiary to so be in good standing or to be qualified to do business in any such jurisdiction or the failure of any such Subsidiary to be so
validly existing, in each case, to the extent any such failure would not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 

  
 53 

 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

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 (x) have been or will be, on or prior to the time required, obtained or made and are or will be, as applicable, in full force and effect or (y) the failure to have obtained or made which would not
reasonably be expected to result in a Material Adverse Effect, (ii) will not violate (a) any law, rule, 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 would reasonably be expected to, have a Material Adverse Effect with respect to such Borrower, (b) such Borrower’s or any Subsidiary’s (other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC) 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, (c)
the provisions of (x) the Illinois Credit Agreement or (y) 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, which in the case of the immediately preceding clause (y) is known to, or would reasonably be expected to, have a Material Adverse Effect with respect to such Borrower or a material adverse effect on the
priority of the claims of the Agent or the Lenders hereunder or constitute an Event of Default hereunder or (d) will not 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 Illinois Credit Agreement or any such indenture, instrument or agreement, in each case other than a Lien which would not be prohibited hereunder. 

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, 2015, and the unaudited consolidated balance sheets of such Borrower as of March 31, 2016, June 30, 2016 and September 30, 2016, 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 (including by the electronic filing thereof by the Borrowers with the SEC as provided in Section 6.1 below), were prepared in accordance with GAAP 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, 2016, June 30, 2016 and September 30, 2016, to the absence of

  
 54 

 
footnotes and to year-end audit adjustments) and fairly present in all material respects the consolidated financial condition and results of 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 3 hereto, neither such
Borrower nor any of its Subsidiaries has as of the Restatement Effective Date any material contingent liabilities. 
 5.5. Material
Adverse Change. As of the Restatement Effective Date, since December 31, 2015, there has been no change in the business, Property, financial condition or results of operations of such Borrower and its Subsidiaries (other than any
Project Finance Subsidiary), taken as a whole, that would 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 would 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 Restatement Effective 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 would 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. 
 5.8. 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, would reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 

5.9. 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. 

  
 55 

 5.10. 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 hereunder or under any credit facility with
any Lender or Affiliate of a Lender, or any other restriction hereunder. 
 5.11. Compliance with Laws. Except for the Disclosed
Matters, such Borrower and its Subsidiaries have complied 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 would reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. 

5.12. 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 Restatement Effective 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), would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect with respect to such Borrower. 

5.13. Investment Company Act. Such Borrower is not an “investment company” or a company “controlled” by an
“investment company”, within the meaning of the Investment Company Act of 1940. 
 5.14. Anti-Corruption Laws and
Sanctions. The Company maintains and will maintain in effect policies and procedures designed to ensure compliance by the Company, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and
applicable Sanctions, and the Company and its Subsidiaries and, to the knowledge of the Company, their respective officers, employees, directors and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material
respects. None of (a) the Company, any of its Subsidiaries or, to the knowledge of the Company, any of their respective directors, officers or employees, or (b) to the knowledge of the Company, any agent of the Company or of any of its
Subsidiaries that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person. No borrowing or use of the proceeds thereof will
result in a violation by any party hereto of Anti-Corruption Laws or applicable Sanctions.

 ARTICLE VI 

COVENANTS 
 During the

Non-Material Subsidiary or SPC) to pay when due (after the expiration of any applicable grace or cure periods) any principal of or interest on any of their Material Indebtedness, or the default by such
Borrower or any of its Subsidiaries (other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC) in the performance (beyond the applicable grace period with respect thereto, if any) of any other
term, provision or condition contained in any of their respective Material Indebtedness Agreements or any other event shall occur or condition exist, the effect of which default, event or condition is to cause, or to permit the holder(s) of such
Material Indebtedness or the lender(s) under any such Material Indebtedness Agreement to cause, such Material Indebtedness to become due, or to be required to be prepaid or repurchased (other than by a regularly scheduled payment or a mandatory
prepayment of a corresponding receipt by such Borrower or such Subsidiary (such as from the proceeds of sale, transfer, loss or other disposition of property or the issuance of Indebtedness, equity or other securities)) prior to its stated maturity
or, solely with respect to the Company with respect to the Illinois Credit Agreement, any commitment to lend to such Borrower thereunder to be terminated prior to its stated expiration date; or, as a result of any of the foregoing, any Material

transaction the Material Indebtedness thereunder is repaid in full with respect to the Borrower or Subsidiary which would otherwise have been in default of such Material Indebtedness Agreement (and, if such Material Indebtedness Agreement is the
Illinois Credit Agreement, the commitments available thereunder to such Borrower or Subsidiary are terminated); and provided further that any “Default” of the Company under the Illinois Credit Agreement that consists solely of, or
termination of any commitment to lend under the Illinois Credit Agreement that results solely from, a default by the “Borrowing Subsidiary” or any of its “Subsidiaries” thereunder and as defined therein shall not constitute a

mandated time period therefor (or any extension thereof) to contest in good faith any appointment or proceeding described in Section 7.7, or (vii) become unable, admit in writing its inability or fail generally to pay its debts as they become due.

 7.7. Without the application, approval or consent of such Borrower or any of its Subsidiaries (other than any Project Finance Subsidiary,
Non-Material Subsidiary or SPC ), a receiver, trustee, examiner, liquidator or similar official shall be appointed for such Borrower or any of its Subsidiaries (other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC) or any Substantial Portion of its Property or the Property of any of its Subsidiaries (other than any Project Finance Subsidiary, Non-Material
Subsidiary or 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 bankrupt or insolvent, or seeking dissolution, winding up, liquidation, reorganization,

(other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC) of any term, provision or condition contained in one or more Rate Management Transactions or other swap, forward, future or

transactions, options or similar transactions resulting in liability of such Borrower or such Subsidiaries for obligations and/or settlement amounts under such Rate Management Transactions or other swap, forward, future or derivative transactions,
options or similar transactions in an aggregate amount of $100,000,000 or more (after giving effect to all netting arrangements and agreements); provided that no Default shall occur under this Section 7.10 as a result of (i) any notice of voluntary

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, to the Company) shall automatically terminate and the Obligations of such Borrower (and, if such
Borrower is the Borrowing Subsidiary, of the Company) shall immediately become 

  
 69 

 
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, (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 the definition of the term “Pro Rata
Share” or 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 or (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, and (iii) no such agreement shall amend, modify, extend or otherwise affect the rights or obligations of the Agent or any Issuing Bank without the prior written consent of the Agent or
such Issuing Bank, as the case may be. 

  
 70 

 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.

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.

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 

  
 71

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

paralegals for the Agent, the Arrangers, the Issuing Banks and the Lenders, which attorneys and paralegals may be employees of the Agent, the Arrangers, the Issuing Banks or the Lenders) paid or incurred by the Agent, such Arranger, any Issuing Bank

(c) below, the Borrowers hereby further agree to indemnify the Agent, each Arranger, each Issuing Bank, 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, any Lender or any Affiliate is
a party thereto, and all attorneys’ and 

  
 72 

 
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, (i) from the gross negligence or willful misconduct of the party seeking indemnification, (ii) 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) or (iii) from claims of one or more indemnified parties against another indemnified party (other than claims against the Agent (or any other
designated agent), any Issuing Bank or any Arranger in their capacities as such) and not involving any act or omission of the Borrowers or their subsidiaries or any of their respective Affiliates (or any such person’s officers, directors,
employees, advisors, agents or representatives). 
 (c) Each amount payable under paragraph (a) or (b) of this Section shall be an
obligation of, and shall be discharged by (i) to the extent arising out of acts, events and circumstances related to a particular Borrower, such Borrower, and (ii) otherwise, both Borrowers, with each of them being severally, but not

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). 
 (d) To the extent that the Borrowers fail to pay any amount required to be paid by them to the Agent, any
Arranger or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Agent, the Arrangers 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 or such Issuing Bank in its capacity as such. 
 (e) 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. 

(f) No indemnified party referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients
of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or
thereby, except to the extent resulting from the gross negligence or willful misconduct of such disclosing party or other indemnified party, as determined by a final non-appealable judgment of a court of competent jurisdiction.

 9.7. [Reserved]. 

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 either 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 the Company, 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, as they relate solely to such change, shall
mean generally accepted accounting principles as of the date of such amendment. Notwithstanding the foregoing, all financial statements to be delivered by the Borrowers 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, (a) for purposes of all financial or covenant
calculations made under this Agreement and for purposes of defining and calculating Capitalized Leases, Capitalized Lease Obligations, Indebtedness and Funded Debt hereunder for such purposes, all leases or other agreements of any Person deemed to
be a lease under GAAP (as in effect from time to time) (whether such lease or other agreement is existing as of the date hereof or hereafter entered into) that would not be characterized as (i) a Capitalized Lease under GAAP as in effect as of
December 31, 2015 or (ii) (1) a Capitalized Lease Obligation, (2) Indebtedness or (3) Funded Debt, in each case, under this Agreement as in effect as of the Restatement Effective Date, will not be deemed to be (i) a
Capitalized Lease or finance lease as a result of any change in GAAP occurring or coming into or taking effect after December 31, 2015, or (ii) (1) a Capitalized Lease Obligation, (2) Indebtedness or (3) Funded Debt,
respectively, as a result of any change in GAAP occurring or coming into or taking effect after the Restatement Effective Date, including, in the case of each of clauses (i) and (ii), ASC Topic 840 or 842 or any similar or successor
pronouncement or rule and (b) 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,
(i) without giving effect to any election under Statement of Financial Accounting Standards 159, The Fair Value Option for Financial Assets and Financial Liabilities, or any successor thereto (including pursuant to the Accounting Standards
Codification), to value any Indebtedness at “fair value”, as defined therein, (ii) without giving effect to any treatment of Indebtedness in respect of convertible debt instruments under Accounting Standards Codification 470-20 (or any
other Accounting Standards Codification or Financial Accounting Standard having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein, and such Indebtedness shall at all times be valued at
the full stated principal amount thereof. 

  
 74 

 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 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, 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 

  
 75 

 
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, (xii) to 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 and (xiii) information
that is of the type routinely provided by arrangers to data service providers, including league table providers, that serve the lending industry, such as information identifying the Company, the type, amount and maturity of the credit facility
established hereby and the roles and titles of the Arrangers and Agents named on the cover hereof (but excluding any confidential information relating to the Borrowers). 

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, each Lender and each 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 or Issuing Bank to identify
the Borrowers in accordance with its requirements. The Borrowers shall, promptly following a request by the Agent or any Lender or Issuing Bank, provide all 

  
 76 

 
documentation and other information that the Agent or such Lender or Issuing Bank 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.

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. 

  
 77 

 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 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 

  
 78 

 
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, facsimile, 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), (a) 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, (b) 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 (c) 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. 

  
 79 

 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, 45 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 30 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, 

  
 80 

 
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. 
 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 October 28, 2016 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. 
 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. 

  
 81 

 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 resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans
and participations in LC Disbursements 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 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; 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 Section 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 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, each Lender and each Issuing Bank (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
Defaulting Lender, 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 or delayed) 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; 

  
 82 

 (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; and 
 (C) each Issuing Bank. 

 

	 	(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; 

(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

  
 83 

	 	
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, acting solely for this purpose as a non-fiduciary agent, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation 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. 

  

	 	(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 and any tax forms required by
Section 3.5(e) (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 or any Issuing Bank, 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 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 

  
 84 

	 	
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 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 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 or other central banking authority, 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.

 “Level II Status” exists at any date if, on such date, (i)
the applicable entity has not qualified for Level I Status and (ii) the applicable entity’s Moody’s Rating is A2 or better and the applicable entity’s S&P Rating is A or better. 

“Level III Status” exists at any date if, on such date, (i) the applicable entity has not qualified for Level I Status or

 EXHIBIT A 

[FORM OF] 
 BORROWERS’
COUNSEL’S OPINION 
 See attached. 

 December 7, 2016 

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 Amended and
Restated Credit Agreement dated as of December 7, 2016 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 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. Each of the Borrowers is a corporation, 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 to which such Borrower is a party. The execution and delivery by each of the Borrowers of the Loan Documents to which such Borrower is a
party, and the performance by each of the Borrowers of its obligations under the Loan Documents to which such Borrower is a party, 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 to which such Borrowers are parties, nor the consummation of
the transactions contemplated therein, nor the performance by the Borrowers of the 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 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 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 such Borrower pursuant to the terms of, any such indenture, instrument or agreement. Except as set forth in opinion paragraph 6 below, 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 the 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 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. 

  
 - 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 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 February 29,
2016, 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 February 29, 2016 FERC Order
expires March 16, 2018. 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 16, 2018. 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 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
your permission, I have assumed that the laws of the State of New York do not differ from the laws 

  
 - 3 - 

 
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 advise you of any change in matters of law or fact set forth herein or upon which this opinion is based.

Loans in Dollars to each Borrower from time to time from and including the Restatement Effective Date and prior to the Availability Termination Date for such Borrower in an amount not to exceed its Pro Rata Share of the Available Aggregate
Commitment; provided that after giving effect thereto and to any repayments of outstanding Obligations made with proceeds of such Revolving Loans, (i) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment,
(ii) the Revolving Credit Exposure of any Lender shall not exceed its Commitment and (iii) the Borrower Credit Exposure of the Borrower requesting any such Revolving Loan shall not exceed the Borrower Sublimit of such Borrower. Subject to
the terms of this Agreement, each Borrower may, severally and not jointly with the other Borrower, borrow, repay and reborrow Revolving Loans at any time prior to the Availability Termination Date for such Borrower. The commitment of each Lender to
lend to a Borrower hereunder shall automatically expire on the Availability Termination Date for such Borrower (as the same may from time to time be extended pursuant to the terms hereof). 

2.2. Required Payments; Termination. Each Borrower, severally and not jointly with the other Borrower, hereby unconditionally promises
to pay to the Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan made by such Lender to such Borrower, (i) in the case of the Company, on the Availability Termination Date for the Company and (ii) in the
case of the Borrowing Subsidiary, on the earlier of the Availability Termination Date for the Borrowing Subsidiary and (without limiting its ability to reborrow hereunder in accordance with the other terms of this Agreement) the date 364 days after

rights and remedies with respect to such Borrower and its Obligations under this Agreement and the other Loan Documents shall survive. 

  
 27 

 2.3. Loans. Each Advance hereunder shall consist of Revolving Loans made by the
Lenders ratably in accordance with their Pro Rata Shares of the Aggregate Commitment. 
 2.4. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, (i) each Issuing Bank agrees to issue to the Borrowing
Subsidiary, upon its request, Letters of Credit for the Borrowing Subsidiary’s 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) each Issuing Bank agrees to issue
to the Company, upon its request, Letters of Credit for the Company’s own account or jointly for its own account and the account of any of its subsidiaries, other than the Borrowing Subsidiary and Union Electric and their 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, and shall constitute, 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 2.6(b) 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 transmit by facsimile (or transmit 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 

  
 28 

 
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 $275,000,000. Notwithstanding the foregoing, no Issuing
Bank shall be required to (A) issue, amend, renew or extend any Letter of Credit (w) other than in Dollars, (x) if 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) if 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 Restatement Effective 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 Restatement Effective 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) if,
for Letters of Credit to be issued jointly for the account of either Borrower and any of its subsidiaries in accordance with Section 2.4(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, (B) issue any Letter of Credit that is a
commercial letter of credit (as opposed to a standby letter of credit) if such Issuing Bank shall have advised the applicable Borrower that it is unable or not approved to do so, or (C) in the case of any Letter of Credit containing an automatic
renewal provision, permit the extension of such Letter of Credit if (x) such Issuing Bank would have no obligation, at such time, to issue such Letter of Credit under the terms hereof and (y) the Issuing Bank gives notice of the non-renewal thereof
to the applicable Borrower and the beneficiary prior to the last date on which, under and pursuant to the terms of such Letter of Credit, such notice will be effective to prevent such renewal. 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 

  
 29 

 
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 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 the earlier of the
Maturity Date 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 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 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 and the LC Commitment Termination Date for such Issuing Bank, in which case the applicable Borrower shall deposit, on or prior to the date that is 90 days prior to the earlier of the Maturity Date 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 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. 

  
 30 

 (e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrower for the account of which 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 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 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 time), on (i) the Business Day on which such Borrower receives such notice, if such notice is received prior to 10:00 a.m. (New York time) on the day of receipt,
or (ii) the Business Day immediately following the day on which 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 that such payment be financed with a Floating Rate Advance 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. 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 2.9 with respect to Loans made by such Lender (and Section 2.9 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 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 

  
 31 

 
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 facsimile) 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 on which such LC Disbursement is made to but excluding the date on which 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 2.12 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 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. 

  
 33 

 (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 Maturity 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 Maturity Date, at which time the Borrowers shall pay any unpaid fees accrued for the account of the terminated Issuing Bank
pursuant to Section 2.6(b). 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. 
 2.5. 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 2.9 and 2.10. 

  
 34 

 2.6. Facility Fee; Letter of Credit Fees; Reductions in Aggregate Commitment and Borrower
Sublimits.
 (a) Facility Fee. Subject to Section 2.22, 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 Restatement Effective Date to and including the Availability Termination Date for such Borrower, payable quarterly in arrears on each Payment Date, commencing on the first Payment Date to
occur after the Restatement Effective Date; 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. 
 (b) 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 a per annum rate equal to such Borrower’s 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 Restatement Effective 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 Restatement
Effective 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 Restatement Effective 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. 

  
 35 

 (c) Termination of and Reductions in Aggregate Commitment and Borrower Sublimits. The
Commitments will automatically terminate on the Maturity Date. The Company (on behalf of itself and the Borrowing Subsidiary) may permanently reduce (subject to its right pursuant to Section 2.23 to subsequently increase) the Aggregate
Commitment (with or without reducing either Borrower’s 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 Business Days’ written notice to the Agent, which notice shall specify,
as applicable, (i) the aggregate amount of any such reduction and/or (ii) the individual amount by which the applicable Borrower Sublimit shall be reduced; provided, however, that (A) the amount of the Aggregate Commitment may not be
reduced below the Aggregate Outstanding Credit Exposure and (B) the Borrower Sublimit of either Borrower may not be reduced below the Borrower Credit Exposure of such Borrower, in each case, giving effect to any prepayment to be made on such
date. Any reduction of the Aggregate Commitment under this paragraph (other than the first sentence hereof) shall reduce ratably the Commitments of all the Lenders. 

2.7. 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. 
 2.8. 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 $5,000,000 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 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 $5,000,000
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 Business Days’ prior notice to the Agent. Any optional payment
of Advances under this Section shall be applied ratably to the Advances of all the Lenders. Failure to make any optional payment of Advances under this Section on the date specified by the applicable Borrower to the Agent shall not constitute a
Default. 
 2.9. 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 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 

  
 36 

 
sole discretion. The applicable Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 1:00 p.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 to each Lender of each request for borrowing under this Section 2.9 by 2:00 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 3:00 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.

2.10. 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 2.10 or are repaid in accordance with Section 2.8. 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 one
month (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 2.8 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 2.7, 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 2.10, 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

  
 37 

 
conversion of a Eurodollar Advance to a Floating Rate Advance not later than 1:00 p.m. (New York time) at least three 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. 

2.11. 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 2.10, as applicable, 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 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 excluding) the earlier of the last day of such Interest Period or the date it is paid in accordance with Section 2.8, 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 2.9 and 2.10 and otherwise in accordance with the terms hereof. 

2.12. 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 2.11 or (ii) in the case of any other amount, 2% per annum plus the rate applicable to Floating Rate Advances as provided in Section 2.11. 

2.13. 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 

  
 38 

 
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 JPMorgan for each payment of principal, interest and fees owed by such Borrower as such payment becomes due hereunder. 

2.14. Noteless Agreement; Evidence of Indebtedness.

(a) 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. 

(b) The Agent shall also maintain accounts in which it will record (i) 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, (ii) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder,
(iii) 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, (iv) the amount of any sum received by the Agent hereunder from each Borrower and each
Lender’s share thereof and (v) all other appropriate debits and credits as provided in this Agreement, including all fees, charges, expenses and interest. 

(c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) 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. 
 (d) Any Lender may request that its
Loans be evidenced by a promissory note in substantially the form of Exhibit D (a “Note”). In such event, the applicable Borrower shall prepare, execute and deliver to such Lender such Note payable to 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 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 (a) and (b) above. 

2.15. Telephonic Notices. Each Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect
selections of Types of Advances and 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. 

  
 39 

 2.16. 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 Restatement Effective Date, on any date on which such Floating Rate Advance is prepaid, whether by 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 such 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 on Eurodollar Advances and fees hereunder shall be
calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances, at times when the Floating Rate Advances are based on the Prime Rate, shall be calculated for actual days elapsed on the basis of a 365/366-day
year, and in each other case shall be payable for the actual number of days elapsed on the basis of a 360-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. 

2.17. 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. 
 2.18. 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. 
 2.19.
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 2.4(e) or (ii) in the case of a Borrower, a payment of principal, interest or fees to the 

  
 40 

 
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. 
 2.20. 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), (c), (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 Declining Lender, 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 and each Issuing Bank (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 (or the applicable portion thereof) 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 

  
 41 

 
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 2.8. 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, in each case, giving effect to all prepayments of the Obligations to be made in connection therewith. 

2.21. Extension of Maturity 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 90 days (or such shorter or longer period, respectively, as may otherwise be agreed to by
the Agent and the Company), before any anniversary of the Restatement Effective Date, request that the Lenders extend the then effective Maturity Date (the “Existing Maturity 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 Maturity Date extension
request, then the Maturity Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Existing Maturity 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 Maturity 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 (in each case, solely with respect to such Declining Lenders and no other Lenders) be due and payable on the Existing Maturity Date, and on the Existing
Maturity 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 Maturity 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 the “Credit Extension Date” therein shall be deemed to refer to such effective date and (B) all references to the “Restatement

  
 42 

 
Effective Date” in (x) Section 4.2.2 as it relates to Sections 5.5, 5.7 and 5.12(ii) and (y) in Sections 5.5, 5.7 and 5.12(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. Notwithstanding any other provision of this Agreement, no Issuing Bank shall have any obligation to issue any Letter of Credit expiring after the Existing
Maturity Date, or to amend, renew or extend any Letter of Credit such that it would expire after the Existing Maturity Date, unless such Issuing Bank shall have consented to the applicable Maturity Date extension (such consent to be deemed given if
such Issuing Bank is a Consenting Lender). 
 2.22. 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 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 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 2.6(b) shall be adjusted in accordance with such
reallocation. 

  

	 	(v)	 If (or to the extent that) 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 (and until and for so long as such condition shall exist), 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

  
 43 

	 	
partial reallocation pursuant to clause (iii) above) in accordance with the procedures set forth in Section 2.4(i) for so long as such unreallocated LC Exposure is outstanding or as otherwise
provided pursuant to Section 2.22(c) below. 

  

	 	(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
2.6(b) 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 2.22. 

 (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) 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, such Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless such Issuing Bank shall have entered into arrangements with the applicable Borrower or such Lender reasonably
satisfactory to such Issuing Bank 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 and each Issuing Bank shall agree that a Defaulting Lender has adequately remedied all matters
that caused such Lender to be a Defaulting Lender, then the 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 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, and all cash collateral then being held pursuant to Section
2.22(a)(v) above in connection with the LC Exposure of such Defaulting Lender shall be released and returned to the applicable Borrower. 

(d) Except as expressly provided in this Section 2.22 in connection with the obligations of the Issuing Banks, the obligation of each Lender
and Issuing Bank 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 2.22 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. 

  
 44 

 2.23. 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 2.23(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 and each Issuing Bank (which approval shall not be unreasonably withheld or delayed) and
shall not be subject to the approval of any other Lenders, and the Borrowers 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 Letters of Credit held by each Lender (including each such Augmenting Lender) will (subject to Section 2.22) 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. 

  
 45 

 (c) Commitment Increases and new Commitments created pursuant to this Section 2.23 shall become
effective on the date specified in the notice delivered by the Borrowers pursuant to the first sentence of paragraph (a) above or on such other date as agreed upon by the Borrowers, 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 “Restatement Effective Date” in Sections 5.5, 5.7 and 5.12(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 2.23 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: 

(a) 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 

(b) 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 
 (c) imposes 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 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 (and 

  
 46 

 
otherwise subject to the terms of Section 3.6), 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 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 and liquidity), then, within 15 days after the submission of the written statement required by Section 3.6 by such Lender or Issuing Bank (and otherwise subject to the terms of Section 3.6), 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 facsimile 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 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 or a Floating Rate Advance is not converted into a Eurodollar Advance on the date specified by the applicable

  
 47 

 
Borrower for any reason other than default by the Lenders, a Eurodollar Advance 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 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 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 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 2.20 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 

  
 48 

 
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 (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 

  
 49 

 
(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 or IRS Form W-8BEN-E 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 or IRS Form W-8BEN-E
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 IRS Form
W-8BEN-E; 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 or IRS Form W-8BEN-E, 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 

  
 50 

 
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 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. 

  
 51 

 (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. 
 (i) For
purposes of determining withholding Taxes imposed under FATCA, from and after the Restatement Effective Date, the Borrowers and the Agent shall treat (and the Lenders hereby authorize the Agent to treat) the Agreement as not qualifying as a
“grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i). 
 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 15 days (or, in the case of Section 3.5, 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 2.20 to replace a Lender. 

  
 52 

 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

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 such Subsidiary to so be in good standing or to be qualified to do business in any such jurisdiction or the failure of any such Subsidiary to be so
validly existing, in each case, to the extent any such failure would not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

Documents and to perform its obligations thereunder. The 

  
 55

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 (x) have been or will be, on or prior to the time required, obtained or made and are or will be, as applicable, in full force and effect or (y) the failure to have obtained or made which would not reasonably be expected to result in a Material
Adverse Effect, (ii) will not violate (a) any law, rule, 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 would reasonably be expected to, have
a Material Adverse Effect with respect to such Borrower, (b) such Borrower’s or any Subsidiary’s (other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC) 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, (c) the provisions of (x) the Union Electric Credit
Agreement or (y) 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, which in the case of
the immediately preceding clause (y) is known to, or would reasonably be expected to, have a Material Adverse Effect with respect to such Borrower or a material adverse effect on the priority of the claims of the Agent or the Lenders hereunder or
constitute an Event of Default hereunder or (d) will not 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, in each case other than a Lien which would not be prohibited hereunder.

March 31, 2016, June 30, 2016 and September 30, 2016, 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 (including by the electronic

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 would 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. 

5.8. 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, would reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

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

Matters, such Borrower and its Subsidiaries have complied 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

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, to the Company) shall automatically terminate and the Obligations of such Borrower (and, if such
Borrower is the Borrowing Subsidiary, of 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. 

  
 72 

 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, (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 the definition of the term “Pro Rata
Share” or 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 or (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, and (iii) no such agreement shall amend, modify, extend or otherwise affect the rights or obligations of the Agent or any Issuing Bank without the prior written consent of the Agent or
such Issuing Bank, 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 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. 

  
 73 

 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.

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).

that they have resulted, as determined in a final non-appealable judgment by a court of competent jurisdiction, (i) from the gross negligence or willful misconduct of the party seeking indemnification, (ii) 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

 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 either 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
the Company, 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,
as they relate solely to such change, shall mean generally accepted accounting principles as of the date of such amendment. Notwithstanding the foregoing, all financial statements to be delivered by the Borrowers 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, (a) for
purposes of all financial or covenant calculations made under this Agreement and for purposes of defining and calculating Capitalized Leases, Capitalized Lease Obligations, Indebtedness and Funded Debt hereunder for such purposes, all leases or
other agreements of any Person deemed to be a lease under GAAP (as in effect from time to time) (whether such lease or other agreement is existing as of the date hereof or hereafter entered into) that would not be characterized as (i) a Capitalized
Lease under GAAP as in effect as of December 31, 2015 or (ii) (1) a Capitalized Lease Obligation, (2) Indebtedness or (3) Funded Debt, in each case, under this Agreement as in effect as of the Restatement Effective Date, will not be deemed
to be (i) a Capitalized Lease or finance lease as a result of any change in GAAP occurring or coming into or taking effect after December 31, 2015, or (ii) (1) a Capitalized Lease Obligation, (2) Indebtedness or (3) Funded Debt, respectively, as a
result of any change in GAAP occurring or coming into or taking effect after the Restatement Effective Date, including, in the case of each of clauses (i) and (ii), ASC Topic 840 or 842 or any similar or successor pronouncement or rule and (b) 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, (i) without giving effect to any election
under Statement of Financial Accounting Standards 159, The Fair Value Option for Financial Assets and Financial Liabilities, or any successor thereto (including pursuant to the Accounting Standards Codification), to value any Indebtedness at
“fair value”, as defined therein, (ii) without giving effect to any treatment of Indebtedness in respect of convertible debt instruments under Accounting Standards Codification 470-20 (or any other Accounting Standards Codification or
Financial Accounting Standard having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein, and such Indebtedness shall at all times be valued at the full stated principal amount thereof.

 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 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, 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

  
 78 

 
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, (xii)
to 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 and (xiii) information that is of the type routinely provided by arrangers
to data service providers, including league table providers, that serve the lending industry, such as information identifying the Company, the type, amount and maturity of the credit facility established hereby and the roles and titles of the
Arrangers and Agents named on the cover hereof (but excluding any confidential information relating to the Borrowers). 
 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, each Lender and each 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 

  
 79 

 
names and addresses of the Borrowers and other information that will allow such Lender or Issuing Bank to identify the Borrowers in accordance with its requirements. The Borrowers shall,
promptly following a request by the Agent or any Lender or Issuing Bank, provide all documentation and other information that the Agent or such Lender or Issuing Bank 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

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 

  
 80 

 
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.

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

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

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.

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

its capacity as Agent, (b) 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 (c) 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. 

  
 82 

 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, 45 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 30 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

  
 83 

 
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.
 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 October 28, 2016 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. 
 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,

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 resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations
in LC Disbursements 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 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; 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 Section 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 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, each Lender and each Issuing Bank (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.

  
 85 

 (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
Defaulting Lender, 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 or delayed) 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; and 

(C) each Issuing Bank. 
  

	 	(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; 

(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. 

  
 86 

	 	(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, acting solely for this purpose as a non-fiduciary agent, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation 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. 

  

	 	(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 and any tax forms required by Section 3.5(e)
(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. 

  
 87 

 (c) Participations.

 

	 	(i)	Any Lender may, without the consent of either Borrower, the Agent or any Issuing Bank, 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 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 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 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 

  
 88 

	 	
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 or other central banking authority, 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.

 Level Status shall be determined based upon the applicable Ratings for the applicable Borrower provided by
Moody’s and S&P. If the applicable Borrower is split-rated, then (a) if the Ratings differential is one level, each rating agency will be deemed to have a Rating corresponding to the higher level and (b) if the Ratings differential is
two levels or more, then each rating agency will be deemed to have a Rating corresponding to the level one level below the higher Rating. For purposes of the foregoing, a rating agency that shall not have a Rating in effect shall be deemed to

the close of business on such date; provided that no upgrade in Ratings shall take effect prior to the receipt by the Agent of notice thereof from either Borrower. 

“Level I Status” exists at any date if, on such date, the applicable entity’s Moody’s Rating is A1 or better and
the applicable entity’s S&P Rating is A+ or better. 
 “Level II Status” exists at any date if, on such date, (i)
the applicable entity has not qualified for Level I Status and (ii) the applicable entity’s Moody’s Rating is A2 or better and the applicable entity’s S&P Rating is A or better. 

“Level III Status” exists at any date if, on such date, (i) the applicable entity has not qualified for Level I Status or
Level II Status and (ii) the applicable entity’s Moody’s Rating is A3 or better and the applicable entity’s S&P Rating is A- or better. 

“Level IV Status” exists at any date if, on such date, (i) the applicable entity has not qualified for Level I Status, Level
II Status or Level III Status and (ii) the applicable entity’s Moody’s Rating is Baa1 or better and the applicable entity’s S&P Rating is BBB+ or better. 

 “Level V Status” exists at any date if, on such date, (i) the applicable entity
has not qualified for Level I Status, Level II Status, Level III Status or Level IV Status and (ii) the applicable entity’s Moody’s Rating is Baa2 or better and the applicable entity’s S&P Rating is BBB or better. 

“Level VI Status” exists at any date if, on such date, the applicable entity has not qualified for Level I Status, Level II
Status, Level III Status, Level IV Status or Level V Status.

RESTRICTIVE AGREEMENTS 

(see Section 6.12) 

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

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 

  
 Schedule 2 Page 1 

 
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 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

[FORM OF] 
 BORROWERS’
COUNSEL’S OPINION 
 See attached. 

 December 7, 2016 

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 Senior Corporate 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 Amended and Restated Credit Agreement dated as of December 7, 2016 (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 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, 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 to which Ameren Illinois is a party. The execution and delivery by Ameren Illinois of, and the performance by Ameren Illinois of its obligations under, the Loan
Documents to which Ameren Illinois is a party 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 to which Ameren Illinois is a party, 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. 
 Except as set forth in opinion paragraph 4 below, 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 Ameren Illinois, is required to be obtained by Ameren Illinois in connection with the execution and delivery of the Loan Documents, the borrowings and issuances of Letters of Credit for account of Ameren Illinois under
the Loan Documents, the payment and performance by Ameren Illinois of its Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents with respect to Ameren Illinois. 

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 August 8, 2016, 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 August 8, 2016 FERC Order expires September 14, 2018 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 

  
 2 

 
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 14, 2018. 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. 

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 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
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.

[FORM OF] 
 BORROWERS’
COUNSEL’S OPINION FOR THE BORROWING SUBSIDIARY 
 See attached. 

 December 7, 2016 

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 Amended and Restated Credit Agreement dated as of December 7, 2016 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, 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 to which the Company is a party. The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Loan Documents to
which the Company is a party 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 to which the Company is a party, 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. Except as set forth in opinion paragraph 6 below, 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 August 8, 2016 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 August 8, 2016 FERC Order expires September 14, 2018 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 14, 2018. 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 your 

  
 3 

 
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.
