 2 

 The Administrative Agent shall notify the parties hereto of the Restatement Effective Date, and such notice
shall be conclusive and binding. 
 Section 4. Effect of Agreement. (a) Except as

conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Credit Document in similar or different circumstances. 
 (b) Upon the occurrence of the Restatement Effective Date, the Administrative Agent shall duly complete and distribute to the Borrower and the Lenders a revised Schedule I to the Credit Agreement

 19 

 
shall be made in accordance with GAAP. In the event that the financial statements generally prepared by Exelon reflect a change in GAAP that affects the computation of any financial ratio or
requirement set forth herein (as contemplated by Section 1.03(b)), the compliance certificate delivered pursuant to Section 5.01(b)(iv) accompanying such financial statements shall include information in reasonable detail reconciling such

ARTICLE II 

THE CREDITS 
 Section 2.01. Extensions of Credit. 
 (a) Subject to the terms
and conditions herein set forth, each Lender agrees, severally and not jointly, to make Advances, at any time and from time to time until the Termination Date, to the Borrower in an aggregate principal amount at any time outstanding not to exceed
such Lender’s Commitment minus an amount equal to such Lender’s Commitment Percentage multiplied by the Outstanding Credits at such time. 

  
 20 

 (b) At no time shall the Outstanding Credits exceed the aggregate Commitments. The Borrower
agrees to prepay Advances (subject to payment of the breakage fee required pursuant to Section 9.05(b)(ii)), satisfy reimbursement obligations and/or deposit funds in the Cash Collateral Account in respect of undrawn Letters of Credit to the
extent required to ensure compliance with this provision at all times. 
 (c) No more than ten Eurodollar Borrowings shall be
outstanding at any one time. 
 (d) Within the foregoing limits, the Borrower may borrow, pay or prepay, subject to the
limitations set forth in Sections 2.12(a), and reborrow Advances hereunder, on and after the date hereof and prior to the Termination Date, subject to the terms, conditions and limitations set forth herein. 

Section 2.02. Advances. 
 (a) Each Advance (other than Swingline Advances, which shall be made by the Swingline Lender in accordance with Section 2.03) shall be made as part of a Borrowing consisting of Advances made by the
Lenders ratably in accordance with their respective Commitments; provided, however, that the failure of any Lender to make any Advance shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood,
however, that no Lender shall be responsible for the failure of any other Lender to make any Advance required to be made by such other Lender). The Advances (other than Swingline Advances) comprising any Borrowing shall be in an aggregate principal
amount that is an integral multiple of $1,000,000 and not less than $5,000,000 (or an aggregate principal amount equal to the remaining balance of the available Commitments). 
 (b) Each Borrowing (other than with respect to Swingline Advances) shall be comprised entirely of Eurodollar Advances or Base Rate Advances, as the Borrower may request pursuant to Section 2.03. Each
Lender may at its option make any Eurodollar Advance by causing any domestic or foreign branch or Affiliate of such Lender to make such Advance; provided that any exercise of such option shall not affect the obligation of the Borrower to
repay such Advance in accordance with the terms of this Agreement. Subject to Section 2.01(c), Borrowings of more than one Type may be outstanding at the same time. 
 (c) Each Lender shall make each Advance to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds to the Administrative Agent in New York, New York, not later
than 12:00 noon, and the Administrative Agent shall, by 2:00 P.M., credit the amounts so received to the account or accounts specified from time to time in one or more notices delivered by the Borrower to the Administrative Agent or, if a Borrowing
shall not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so received to the respective Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the
time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent
on the date of such Borrowing in accordance with this subsection (c) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that

  
 21 

 
such Lender shall not have made such portion available to the Administrative Agent, such Lender and the Borrower (without waiving any claim against such Lender for such Lender’s failure to
make such portion available) severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date
such amount is repaid to the Administrative Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Effective Rate;
provided, however, that should both the Borrower and such Lender repay the Administrative Agent in accordance with this sentence, the Administrative Agent will forthwith return the amount in excess of the portion due to it under this sentence
to the Borrower. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement. 

Section 2.03. Borrowing and Conversion Procedures; Swingline Advances. 

(a) In order to request a Borrowing, the Borrower shall hand deliver or telecopy to the Administrative Agent a duly completed Borrowing
Request (a) in the case of a Eurodollar Borrowing, not later than 10:00 A.M. three Business Days before such Borrowing, and (b) in the case of a Base Rate Borrowing or a Swingline Advance, not later than 10:00 A.M. on the Business Day of
such Borrowing. Such notice shall be irrevocable and shall in each case specify (i) whether the Borrowing then being requested is to comprise Eurodollar Advances or Base Rate Advances or will consist of a Swingline Advance; (ii) the date
of such Borrowing (which shall be a Business Day) and the amount thereof; and (iii) if such Borrowing is to be a Eurodollar Borrowing, the Interest Period with respect thereto, which shall not end after the Termination Date. If no election as
to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be a Base Rate Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is specified in any such notice, then the Borrower shall be deemed
to have selected an Interest Period of one month’s duration. Each Swingline Advance shall be made and maintained as a Base Rate Advance at all times. 
 (b) The Borrower may on any Business Day, by delivering a notice of conversion (a “Notice of Conversion”) to the Administrative Agent not later than 10:00 A.M. on the third
Business Day prior to the date of the proposed Conversion, and subject to the provisions of Sections 2.09 and 2.13, Convert any Borrowing of one Type or for one Interest Period into a Borrowing of another Type or for another Interest Period (other
than Swingline Advances); provided, however, that any Conversion of any Eurodollar Borrowing shall be made on, and only on, the last day of an Interest Period. Each such Notice of Conversion shall be in substantially the form of Exhibit I
hereto and shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Borrowings to be Converted, (iii) if such Conversion will result in a Eurodollar Borrowing, the duration of the Interest
Period for such Eurodollar Borrowing, and (iv) the aggregate amount of Borrowings proposed to be Converted. If the Borrower shall not have provided a Notice of Conversion with respect to any Eurodollar Borrowing on or prior to 10:00 A.M. on the
third Business Day prior to the last day of the Interest Period applicable thereto, in the case of a Conversion to or in respect of Eurodollar Advances, or if an Event of Default shall have occurred and be continuing on the third Business Day prior
to the last day of the Interest Period with respect to any Eurodollar Borrowing, the Administrative Agent will 

  
 22 

 
forthwith so notify the Borrower and the Lenders and such Borrowing will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Borrowing.

 (c) Notwithstanding any other provision of this Agreement to the contrary, no Borrowing shall be requested or Converted if
the Interest Period with respect thereto would end after the Termination Date. The Administrative Agent shall promptly advise the Lenders of any notice given pursuant to this Section 2.03 and of each Lender’s portion of the requested
Borrowing or Conversion. 
 (d) Subject to the terms and conditions of this Agreement, the Swingline Lender, in reliance upon
the agreements of the other Lenders set forth in this Section 2.03, may in its sole discretion make Swingline Advances to the Borrower from time to time from on or after the date hereof through, but not including, the Termination Date;
provided, that the aggregate principal amount of all Swingline Outstandings (after giving effect to any amount requested), shall not exceed the Swingline Commitment, and that the Outstanding Credits of any Lender (after giving effect to any
amount requested) shall not exceed such Lender’s Commitment; and provided further, that the Borrower shall not use the proceeds of any Swingline Advance to refinance any outstanding Swingline Advance. Each Swingline Advance shall be in
an aggregate principal amount of $5,000,000 or any larger multiple of $1,000,000 (except that any such Swingline Advance may be in the aggregate amount of the unused Swingline Commitment). The Borrower shall repay to the Swingline Lender the
outstanding principal amount of all Swingline Advances on the earlier of (i) 10 Business Days after the date a Swingline Advance is made and (ii) the Termination Date. Within the foregoing limits, the Borrower may borrow, repay and
reborrow Swingline Advances, in each case under this Section 2.03. 
 (e) Swingline Advances shall be refunded by the
Lenders on demand by the Swingline Lender. Such refundings shall be made by the Lenders in accordance with their respective Commitment Percentages and shall thereafter be reflected as Advances of the Lenders on the books and records of the
Administrative Agent. Each Lender shall fund its Commitment Percentage of Advances required to repay Swingline Advances outstanding upon demand by the Swingline Lender but in no event later than 1:00 P.M. (Charlotte, North Carolina time) on the next
succeeding Business Day after such demand is made. No Lender’s obligation to fund its Commitment Percentage of a Swingline Advance shall be affected by any other Lender’s failure to fund its Commitment Percentage of a Swingline Advance,
nor shall any Lender’s Commitment Percentage be increased as a result of any such failure of any other Lender to fund its Commitment Percentage of a Swingline Advance. 
 (f) The Borrower shall pay to the Swingline Lender on demand, the outstanding principal amount of all Swingline Advances to the extent amounts received from the Lenders are not sufficient to repay in full
the outstanding Swingline Advances requested or required to be refunded. In addition, the Borrower hereby authorizes the Administrative Agent to charge any account maintained by the Borrower with the Swingline Lender (up to the amount available
therein) in order to immediately pay the Swingline Lender the outstanding principal amount of such Swingline Advances to the extent amounts received from the Lenders are not sufficient to repay in full the outstanding principal amount of the
Swingline Advances requested or required to be refunded. If any portion of any such amount paid to the Swingline Lender shall be recovered by or on behalf of the Borrower from the Swingline Lender in bankruptcy or

  
 23 

 
otherwise, the loss of the amount so recovered shall be ratably shared among all the Lenders in accordance with their respective Commitment Percentages (unless the amounts so recovered by or on
behalf of the Borrower pertain to a Swingline Advance extended after the occurrence and during the continuance of an Event of Default of which the Administrative Agent has received notice in the manner required pursuant to Section 5.01(b) and
which such Event of Default has not been waived in accordance with Section 9.08). 
 (g) Each Lender acknowledges and
agrees that its obligation to refund Swingline Advances (other than Swingline Advances extended after the occurrence and during the continuation of an Event of Default of which the Administrative Agent has received notice in the manner required
pursuant to Section 5.01(b) and which such Event of Default has not been waived in accordance with Section 9.08) in accordance with the terms of this Section is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Article III. Further, each Lender agrees and acknowledges that if prior to the refunding of any outstanding Swingline Advance pursuant to this Section, any
event described in Section 7.01(e) or (f) shall have occurred, each Lender will, on the date the applicable Advance would have been made, purchase an undivided participating interest in such Swingline Advance to be refunded in an amount
equal to its Commitment Percentage of the aggregate amount of such Swingline Advance. Each Lender will immediately transfer to the Swingline Lender, in immediately available funds, the amount of its participation, and upon receipt of such amount the
Swingline Lender will deliver to such Lender a certificate evidencing such participation dated the date of receipt of such funds and for such amount. Whenever, at any time after the Swingline Lender has received from any Lender such Lender’s
participating interest in a Swingline Advance, the Swingline Lender receives any payment on account thereof, the Swingline Lender will distribute to such Lender its participating interest in such amount (appropriately adjusted, in the case of
interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded). 
 Section 2.04. Letters of Credit. 
 (a) Upon the written request
of the Borrower and subject to the terms and conditions hereof, an LC Bank, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, shall issue Letters of Credit hereunder for the account of the Borrower or any of
its Subsidiaries; provided that the Borrower shall be the account party for the purposes of this Agreement and shall have the reimbursement obligations with respect thereto. Each Letter of Credit shall be issued in a form acceptable to the
issuing LC Bank. Each Letter of Credit shall be issued (or the stated maturity thereof extended or terms thereof modified or amended) on not less than two Business Days’ (or such shorter period as may be agreed to by the Borrower and the
applicable LC Bank) prior notice thereof by delivery of (x) a Request for Issuance of a Letter of Credit and (y) a Letter of Credit Application to such LC Bank (with a copy to the Administrative Agent, which shall promptly forward copies
thereof to the Lenders). Each such Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated
expiry date thereof (which shall be no later than the earliest to occur of (x) one year after the date of issuance (or later, with the consent of the applicable LC Bank, subject to the limitation in clause (y) below) and (y) the fifth
Business Day preceding the Termination Date; provided, that Auto-Extension Letters of Credit will be permitted, subject to the limitation in clause (y) above 

  
 24 

 
and subsection (b) below), (ii) the proposed stated amount of such Letter of Credit, (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a
statement of drawing conditions applicable to such Letter of Credit, and if such request for issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit
thereto. Each Request for Issuance of a Letter of Credit shall be irrevocable unless modified or rescinded by the Borrower not less than one Business Day prior to the proposed date of issuance (or effectiveness) specified therein. Unless the
applicable LC Bank has received written notice from any Lender or the Administrative Agent, at least one Business Day prior to the requested date of issuance or amendment specified in such Request for Issuance, that one or more applicable conditions
contained in Section 3.01 or 3.02 shall not then be satisfied, then, subject to the terms and conditions hereof, the applicable LC Bank shall, not later than 12:00 noon on such requested date, issue (or extend, amend or modify) such Letter of
Credit and provide notice and a copy thereof to the Borrower and to the Administrative Agent, in each case in accordance with the LC Bank’s usual and customary business practices. The Administrative Agent shall furnish (i) to each Lender,
a copy of such notice and (ii) to each Lender that may so request, a copy of such Letter of Credit. The LC Bank shall provide to the Administrative Agent, on a monthly basis, a list of the amounts and expiration dates of all undrawn Letters of
Credit, a copy of which list the Administrative Agent shall furnish to each Lender that may so request. No Letter of Credit shall be amended or modified after issuance (i) other than in accordance with its terms, which terms permit reductions
by the beneficiary by delivery of a certificate attached to such Letter of Credit, or (ii) without the prior written consent of the Borrower, which consent may be sent by telecopy. 

(b) If the Borrower so requests in any Request for Issuance or Letter of Credit Application, the applicable LC Bank shall issue a Letter
of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit such LC Bank to prevent any such extension at least
once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such
twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by such LC Bank, the Borrower shall not be required to make a specific request to such LC Bank for any such extension. Once an
Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) such LC Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than the day that is five
Business Days prior to the Termination Date then in effect (or, if such day is not a Business Day, the next preceding Business Day); provided, however, that such LC Bank shall not permit any such extension if (A) such LC Bank has
determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of Section 2.04(a) or (d) or
otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the Non-Extension Notice Date from the Administrative Agent that an Event of Default has occurred and is
continuing. 
 (c) If the Borrower so requests in any Request for Issuance or Letter of Credit Application, the applicable LC
Bank may, in its sole discretion, agree to issue a Letter of Credit that permits the automatic reinstatement of all or a portion of the stated amount thereof after any drawing thereunder (each, an “Auto-Reinstatement Letter of
Credit”). Unless otherwise 

  
 25 

 
directed by such LC Bank, the Borrower shall not be required to make a specific request to such LC Bank to permit such reinstatement. Once an Auto-Reinstatement Letter of Credit has been issued,
the Lenders shall be deemed to have authorized (but may not require) such LC Bank to reinstate all or a portion of the stated amount thereof in accordance with the provisions of such Letter of Credit; provided, however, that such LC
Bank shall not permit any such reinstatement if such LC Bank has determined that it would not be permitted, or would have no obligation, at such time to reinstate such Letter of Credit under the terms hereof (by reason of the provisions of the first
sentence of Section 2.04(d) or otherwise). 
 (d) No Letter of Credit shall be requested, issued, extended or reinstated
hereunder if, after the issuance, extension or reinstatement thereof, (i) the LC Outstandings would exceed the LC Committed Amount, (ii) the Outstanding Credits would exceed the aggregate Commitments or (iii) the LC Outstandings with
respect to all Letters of Credit issued by any LC Bank would exceed the Fronting Commitment of such LC Bank. No LC Bank shall be under any obligation to issue any Letter of Credit if (A) any order, judgment or decree of any Governmental
Authority or arbitrator shall by its terms purport to enjoin or restrain such LC Bank from issuing such Letter of Credit, (B) any law applicable to such LC Bank or any request or directive (whether or not having the force of law) from any
Governmental Authority with jurisdiction over such LC Bank shall prohibit, or request that such LC Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such LC Bank with respect
to such Letter of Credit any restriction, reserve or capital requirement (for which such LC Bank is not otherwise compensated hereunder) not in effect on the Original Agreement Date, or shall impose upon such LC Bank any unreimbursed loss, cost or
expense that was not applicable on the Original Agreement Date and that such LC Bank in good faith deems material to it, (C) the issuance of such Letter of Credit would violate one or more policies of such LC Bank or (D) any Lender is at
that time a Defaulting Lender, unless such LC Bank has entered into arrangements, including the delivery of cash collateral, satisfactory to such LC Bank (in its sole discretion) with the Borrower or such Lender to eliminate such LC Bank’s
actual or potential Fronting Exposure (after giving effect to Section 9.15(a)(iv)) with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other LC Outstandings
as to which such LC Bank has actual or potential Fronting Exposure, as it may elect in its sole discretion. 
 (e) The Borrower
hereby agrees to pay to the Administrative Agent for the account of the applicable LC Bank, no later than the second Business Day following demand made by such LC Bank or the Administrative Agent, on and after the date on which such LC Bank shall
pay any amount under any Letter of Credit issued by it, a sum equal to the amount so paid plus interest on such amount from the date so paid by such LC Bank until repayment to such LC Bank in full at a fluctuating interest rate per annum
equal to the Base Rate plus the Applicable Margin for Base Rate Advances plus, if any amount paid by such LC Bank under a Letter of Credit is not reimbursed by the Borrower on or prior to the date when due under this clause (e) (whether
with the proceeds of Advances or otherwise), 2%. 
 (f) If the Borrower shall not have reimbursed the LC Bank for any
Unreimbursed LC Disbursement by 10:00 A.M. on the second Business Day following demand for payment by an LC Bank or the Administrative Agent pursuant to subsection (e) above, then, unless the Borrower shall have notified the Administrative
Agent otherwise, the LC Bank shall promptly 

  
 26 

 
deliver notice of such failure to reimburse to the Administrative Agent, and the Borrower shall be deemed to have delivered to the Administrative Agent a Borrowing Request for a Borrowing to be
made on such date comprising Base Rate Advances in an aggregate principal amount equal to the principal amount of such Unreimbursed LC Disbursement. The Administrative Agent shall deliver prompt notice of such Borrowing Request to the Lenders, and
each Lender shall make the Advance to be made by it in connection with such Borrowing in accordance with Section 2.02(c); provided, however, the proceeds of such Advances shall be credited solely to the account of the applicable LC Bank
in order to reimburse such LC Bank for such Unreimbursed LC Disbursement. If and to the extent that any Lender shall have funded its participation in such Unreimbursed LC Disbursement pursuant to subsection (h) below prior to the time that such
Lender is required to fund its Advance under this subsection (f) pursuant to a Borrowing made to reimburse the LC Bank for such Unreimbursed LC Disbursement, then such participation interest shall be deemed to be such Lender’s Advance made
as part of such Borrowing, and such Lender shall have no further obligation to fund an Advance as part of such Borrowing. Notwithstanding anything to the contrary in this subsection (f), if the conditions precedent to Extensions of Credit in
Section 3.02 are not satisfied on the date the Borrowing Request described above is deemed to be given by the Borrower, then amounts funded by the Lenders under this subsection (f) will not constitute Advances hereunder but will constitute
participations purchased by the Lenders in the applicable Unreimbursed LC Disbursement pursuant to subsection (h) below. 

(g) Upon the issuance of any Letter of Credit by an LC Bank, such LC Bank hereby sells and transfers to each Lender, and each Lender
hereby acquires from such LC Bank, an undivided interest and participation to the extent of such Lender’s Commitment Percentage in and to such Letter of Credit, including the obligations of such LC Bank under and in respect thereof and the
Borrower’s reimbursement and other obligations in respect thereof, whether now existing or hereafter arising. 
 (h) Each
Lender, upon issuance of a Letter of Credit, shall be deemed to have purchased without recourse a risk participation from the applicable LC Bank in such Letter of Credit and the rights and obligations arising thereunder, in each case in an amount
equal to its Commitment Percentage of the obligations under such Letter of Credit, and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the applicable LC Bank therefor and
discharge when due, its Commitment Percentage of the obligations arising under such Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, if an LC Bank shall not have been reimbursed in
full for any payment made by such LC Bank under any Letter of Credit on the date of such payment, such LC Bank shall promptly notify the Administrative Agent and the Administrative Agent shall promptly notify each Lender of such non-reimbursement
and the amount thereof. Upon receipt of such notice from the Administrative Agent, each Lender shall pay to the Administrative Agent for the account of such LC Bank an amount equal to such Lender’s Commitment Percentage of such Unreimbursed LC
Disbursement, plus interest on such amount at a rate per annum equal to the Federal Funds Effective Rate from the date of such payment by such LC Bank to the date of payment to such LC Bank by such Lender. All such payments by each Lender
shall be made in United States dollars and in same day funds not later than 3:00 P.M. on the later to occur of (A) the Business Day immediately following the date of such payment by such LC Bank and (B) the Business Day on which such
Lender shall have received notice of such non-reimbursement; provided, however, that if such notice is received by 

  
 27 

 
such Lender later than 11:00 A.M. on such Business Day, such payment shall be payable on the next Business Day. Each Lender agrees that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever. If a Lender shall have paid to such LC Bank its ratable portion of any Unreimbursed LC Disbursement, together with all interest thereon required by the second sentence of this subsection (h), such
Lender shall be entitled to receive its ratable share of all interest paid by the Borrower in respect of such Unreimbursed LC Disbursement. If such Lender shall have made such payment to such LC Bank, but without all such interest thereon required
by the second sentence of this subsection (h), such Lender shall be entitled to receive its ratable share of the interest paid by the Borrower in respect of such Unreimbursed LC Disbursement only from the date it shall have paid all interest
required by the second sentence of this subsection (h). 
 (i) The failure of any Lender to make any payment to an LC Bank in
accordance with subsection (f) or (h) above shall not relieve any other Lender of its obligation to make payment, but neither such LC Bank nor any Lender shall be responsible for the failure of any other Lender to make such payment. If any
Lender shall fail to make any payment to an LC Bank in accordance with subsection (f) or (h) above, then such Lender shall pay to such LC Bank forthwith on demand such corresponding amount together with interest thereon, for each day until
the date such amount is repaid to such LC Bank at the Federal Funds Effective Rate. Nothing herein shall in any way limit, waive or otherwise reduce any claims that any party hereto may have against any non-performing Lender. 

(j) If any Lender shall fail to make any payment to an LC Bank in accordance with subsection (f) or (h) above, then, in
addition to other rights and remedies that such LC Bank may have, the Administrative Agent is hereby authorized, at the request of such LC Bank, to withhold and to apply to the payment of such amounts owing by such Lender to such LC Bank and any
related interest, that portion of any payment received by the Administrative Agent that would otherwise be payable to such Lender. In furtherance of the foregoing, if any Lender shall fail to make any payment to an LC Bank in accordance with
subsection (f) or (h) above, and such failure shall continue for five Business Days following written notice of such failure from such LC Bank to such Lender, such LC Bank may acquire, or transfer to a third party acceptable to the
Borrower, such acceptance, not to be unreasonably withheld, in exchange for the sum or sums due from such Lender, such Lender’s interest in the related Unreimbursed LC Disbursement and all other rights of such Lender hereunder in respect
thereof, without, however, relieving such Lender from any liability for damages, costs and expenses suffered by such LC Bank as a result of such failure, and prior to such transfer, such LC Bank shall be deemed, for purposes of Section 2.15 and
Article VII hereof, to be a Lender hereunder owed an Advance in an amount equal to the outstanding principal amount due and payable by such Lender to the Administrative Agent for the account of such LC Bank pursuant to subsection (f) or
(h) above. The purchaser of any such interest shall be deemed to have acquired an interest senior to the interest of such Lender and shall be entitled to receive all subsequent payments that such LC Bank or the Administrative Agent would
otherwise have made hereunder to such Lender in respect of such interest. 
 (k) The payment obligations of the Borrower under
Section 2.04(e) in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be paid 

  
 28 

 
strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances: 

(i) any lack of validity or enforceability of this Agreement or any other agreement or instrument relating thereto or to such Letter of
Credit; 
 (ii) any amendment or waiver of, or any consent to departure from, the terms of this Agreement or such Letter of
Credit; 
 (iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any
beneficiary, or any transferee, of such Letter of Credit (or any Person for which any such beneficiary or any such transferee may be acting), or any other Person, whether in connection with this Agreement, the transactions contemplated thereby or by
such Letter of Credit, or any unrelated transaction; 
 (iv) any statement or any other document presented under such Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 
 (v) payment in good faith by an LC Bank under a Letter of Credit against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; 

(vi) any failure to issue a Letter of Credit (or any amendment thereto) in accordance with the specifications set forth by the Borrower
pursuant to Section 2.04(a), provided that the Borrower may cause such a Letter of Credit (or such amendment) to be replaced or rescinded if (A) it provides written notice to the applicable LC Bank (which shall promptly forward
copies to the Administrative Agent for distribution to the Lenders) of any discrepancy from such specifications within three Business Days after the Borrower shall have received a copy of such Letter of Credit (or such amendment), (B) such
discrepancy is material and consequential, and (C) the beneficiary of such Letter of Credit consents in writing to such replacement or revocation; 
 (vii) any claim or potential claim for breach of warranty by the applicable LC Bank, the Lenders or the Borrower against the beneficiary of a Letter of Credit; 

(viii) any action or inaction taken or not taken by an LC Bank or any of its correspondents in connection with any Letter of Credit or
any sight draft, certificate or other document presented pursuant thereto, if taken or not taken, as the case may be, in good faith and in conformity with applicable law. 
 (l) Without limiting any other provision of this Section 2.04, for purposes of this Section 2.04 each LC Bank and any of its respective correspondents: 

(i) may rely upon any oral, telephonic, telegraphic, facsimile, electronic, written or other communication believed in good faith to have
been authorized by the Borrower, whether or not given or signed by an authorized person of the Borrower; 

  
 29 

 (ii) shall not be responsible for errors, omissions, interruptions or delays in transmission
or delivery of any message, advice or document in connection with a Letter of Credit, whether transmitted by courier or facsimile, or for errors in interpretation of technical terms or in translation (and such LC Bank and its correspondents may
transmit Letter of Credit terms without translating them), other than those errors resulting from gross negligence or willful misconduct of such LC Bank or such correspondent, as the case may be, as determined by a final judgment of a court of
competent jurisdiction; 
 (iii) shall not be responsible, absent the gross negligence or willful misconduct of such LC Bank or
its correspondents, as determined by a final judgment of a court of competent jurisdiction, for verifying the identity or authority of any signer of, or the form, accuracy, genuineness, falsification or legal effect of, any draft, certificate or
other document presented under any Letter of Credit if such draft, certificate or other document on its face appears to be in order; 
 (iv) shall not be responsible for any acts or omissions by, or the solvency of, the beneficiary of any Letter of Credit or any other person or entity having any role in any transaction underlying such
Letter of Credit; 
 (v) may accept or pay as complying with the terms and conditions of any Letter of Credit, any draft,
certificate or other document appearing on its face (i) substantially to comply with the terms and conditions of such Letter of Credit, (ii) to be signed or presented by, or issued to any successor of, the beneficiary or any other person
required or authorized by such Letter of Credit to sign or present any sight draft, certificate or other document under such Letter of Credit, including any administrator, executor, personal representative, trustee in bankruptcy, debtor in
possession, liquidator, receiver, or successor by merger or consolidation, or any other person or entity purporting to act as the representative of or in place of any of the foregoing, or (iii) to have been signed, presented or issued after a
change of name of the beneficiary of such Letter of Credit; 
 (vi) may disregard any discrepancies known to it in any Letter of
Credit that do not reduce, in the good faith judgment of such LC Bank or its correspondents, the value of the performance to the Borrower by the beneficiary of such Letter of Credit in any transaction underlying such Letter of Credit; 

(vii) shall not be responsible for the effectiveness or suitability of any Letter of Credit with respect to the Borrower’s purpose
in requesting such Letter of Credit; 
 (viii) shall not be liable to the Borrower for any consequential or special damages, or
for any damages resulting from any change in the value of any goods or other property subject to or underlying any Letter of Credit; 
 (ix) absent any gross negligence or willful misconduct on part of such LC Bank or its correspondents, as determined by a final judgment of a court of competent jurisdiction, may honor a previously
dishonored presentation under a Letter of Credit, whether pursuant to court order, to settle or compromise any claim wrongfully dishonored, or otherwise, and shall be 

  
 30 

 
entitled to reimbursement of amounts paid under such Letter of Credit to the same extent as if such presentation had been honored initially; and 

(x) may pay amounts owed to any paying or negotiating bank (designated or permitted by the terms of any Letter of Credit) claiming that
it rightfully honored, under the laws or practices of the place where it is located, any sight draft, certificate or other document presented under any Letter of Credit. 
 None of the circumstances described in this Section 2.04(l) shall subject such LC Bank or any of its correspondents to any liability to the Borrower. 

(m) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the
Administrative Agent, any LC Bank, the Lenders nor any of their respective officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any
acts or omissions of any beneficiary or transferee thereof in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (iii) payment by any LC Bank against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference
to such Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under a Letter of Credit, except that the Borrower shall have the right to bring suit against the applicable LC Bank, and the applicable
LC Bank shall be liable to the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower that the Borrower proves were caused by the applicable LC Bank’s willful misconduct or gross negligence, as
determined by a final judgment of a court of competent jurisdiction, including the applicable LC Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft
and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, any LC Bank may accept sight drafts and accompanying certificates presented under the
Letter of Credit issued by such LC Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute
willful misconduct or gross negligence by such LC Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the LC Bank for damages caused by any LC Bank’s willful misconduct or gross negligence, as determined by a final
judgment of a court of competent jurisdiction. 
 (n) The Borrower acknowledges that the rights and obligations of the
applicable LC Bank under any Letter of Credit are independent of the existence, performance or nonperformance of any contract or arrangement underlying such Letter of Credit. The applicable LC Bank may, without incurring any liability to the
Borrower or impairing its entitlement to reimbursement under this Agreement, honor any Letter of Credit despite notice from the Borrower of, and without any duty to inquire into, any defense to payment or any adverse claims or other rights against
the beneficiary of the Letter of Credit or any other person. The applicable LC Bank shall have no duty to request or require the presentation of any document, including any default certificate, not required to be presented under the terms and
conditions of any Letter 

  
 31 

 
of Credit. The applicable LC Bank shall have no duty to seek any waiver of discrepancies from the Borrower, nor any duty to grant any waiver of discrepancies that the Borrower approves or
requests. The applicable LC Bank shall have no duty to extend the expiration date or term of any Letter of Credit or, except as provided under Section 2.04(k)(vi), to issue a replacement letter of credit on or before the expiration date of such
Letter of Credit or the end of such term. The applicable LC Bank shall not be liable to the Borrower under this Section 2.04(n) for any action or inaction by it, unless such action or inaction results from such LC Bank’s gross negligence
or willful misconduct, as determined by a final judgment of a court of competent jurisdiction. 
 (o) Unless otherwise expressly
agreed by the applicable LC Bank and the Borrower when a Letter of Credit is issued, the rules of the ISP shall apply to each Letter of Credit, provided that, if the Borrower wishes to opt out of Rule 3.14 of the ISP for a Letter of Credit,
the Borrower must so request in the Request for Issuance and Letter of Credit Application for such Letter of Credit, and provided further that, if the applicable LC Bank is not so instructed, then Rule 3.14 of the ISP shall be deemed to apply
to such Letter of Credit, and such Letter of Credit shall be deemed outstanding as indicated in the last sentence of the definition of “LC Outstandings”. 
 Section 2.05. Fees 
 (a) Facility Fee. In
consideration of the Commitments being made available by the Lenders, the Borrower agrees to pay to the Administrative Agent, for the pro rata benefit of the Lenders, a facility fee equal to the Facility Fee Rate in effect from time to time
multiplied by the aggregate amount of the Commitments from time to time (regardless of usage), payable in arrears on the last day of each March, June, September and December during the term of such Lender’s Commitment and on the Termination
Date. 
 (b) Letter of Credit Fee. The Borrower agrees to pay to the Administrative Agent for the account of each
Lender a letter of credit fee (the “Letter of Credit Fee”), at a rate per annum equal to the Applicable Margin with respect to Eurodollar Advances on the daily average amount of each such Lender’s Commitment
Percentage multiplied by the LC Outstandings, from the date hereof until the later to occur of the Termination Date and the date on which no Letters of Credit in which such Lender is obligated to participate are outstanding, payable in arrears on
the last day of each March, June, September and December during the term of such Lender’s Commitment, and on such later date. 
 (c) Additional Fees. The Borrower shall pay to the Administrative Agent, for its own account, and to the Arrangers, for their own respective accounts, such other fees as are required to be
paid to it under the Fee Letters. The Borrower shall pay to each LC Bank, for its own account, such other fees relating to the issuance of Letters of Credit as have been or may from time to time be agreed between them. 

(d) Nonrefundable; Basis for Calculation. Once paid, none of the facility fees, the Letter of Credit Fees or other fees
provided for in this Section 2.05 shall be refundable under any circumstances. All fees shall be computed on the basis of the actual number of days elapsed over a year of 360 days. 

  
 32 

 Section 2.06. Repayment of Advances; Evidence of Indebtedness.

 (a) The outstanding principal balance of each Advance, together with accrued and unpaid interest thereon shall be due and
payable on the Termination Date. 
 (b) Each Lender shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness to such Lender resulting from each Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. 

(c) The Administrative Agent shall maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Type
of each Advance made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received
by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof. 
 (d) The entries made in the
accounts maintained pursuant to subsections (b) and (c) of this Section 2.06 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided,
however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Advances and interest thereon in accordance with their
terms. 
 (e) Any Lender may request that its Advances be evidenced by a Note. In such event, the Borrower shall prepare,
execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Advances evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 9.04) be represented by
one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 9.04, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such
Advances once again be evidenced as described in subsections (a) and (b) above. 
 Section 2.07.
Interest. 
 (a) Subject to the provisions of subsection (d) below and Sections 2.08, 2.09 and 2.13, the Advances
comprising each Eurodollar Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days), at a rate per annum equal to the Eurodollar Rate for the Interest Period in effect for such
Borrowing plus the Applicable Margin. 
 (b) Subject to the provisions of Sections 2.08, the Advances comprising each Swingline
Advance shall bear interest (computed on the basis of the actual number of days elapsed over a year of 365/366 days) at a rate per annum equal to the Base Rate plus the Applicable Margin for Base Rate Advances. 

(c) Subject to the provisions of Section 2.08, the Advances comprising each Base Rate Borrowing shall bear interest (computed on the
basis of the actual number of days elapsed 

  
 33 

 
over a year of 365/366 days) at a rate per annum equal to the Base Rate plus the Applicable Margin. 
 (d) Interest on each Advance shall be payable in arrears on each Interest Payment Date applicable to such Advance except as otherwise provided in this Agreement. 

(e) The Borrower shall pay to the Administrative Agent for the account of each Lender any costs actually incurred by such Lender in
connection with making or maintaining Extensions of Credit hereunder that are attributable to such Lender’s compliance with regulations of the Board requiring the maintenance of reserves with respect to liabilities or assets consisting of or
including Eurocurrency Liabilities. Such costs shall be paid to the Administrative Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each Eurodollar Advance of such Lender, from the date such
Advance is made until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the
rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each Interest Payment Date for such Advance. Such additional interest
shall be determined by such Lender and notified to the Borrower through the Administrative Agent at least two Business Days prior to the relevant Interest Payment Date, provided, that failure to so notify the Borrower shall not constitute a
waiver of such Lender’s right to request and receive additional interest under this subsection (d). A certificate as to the amount of such additional interest, submitted to the Borrower and the Administrative Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error. Each Lender claiming any additional interest payable pursuant to this subsection shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate
or document reasonably requested in writing by the Borrower or to change the jurisdiction of its Applicable Lending Office if the making of such a filing or change would avoid the need for or reduce the amount of any such additional interest that
may thereafter be due and payable and would not, in the good faith determination of such Lender, be otherwise disadvantageous to such Lender. 
 Section 2.08. Default Interest. 
 Except as otherwise provided
in Section 2.04(e), if and for so long as an Event of Default shall have occurred and be continuing, each Advance outstanding hereunder shall bear interest at the rate otherwise applicable to such Advance plus 2%. Without limiting the
foregoing, if the Borrower shall default in the payment of any amount becoming due hereunder (other than the principal amount of any Advance), whether by scheduled maturity, notice of prepayment, acceleration or otherwise, the Borrower shall on
demand from time to time from the Administrative Agent pay interest, to the extent permitted by law, on such defaulted amount up to (but not including) the date of actual payment (after as well as before judgment) at a rate per annum
(computed as provided in Section 2.07(c)) equal to the Base Rate plus the Applicable Margin for Base Rate Advances plus 2%. 

  
 34 

 Section 2.09. Alternate Rate of Interest. 

In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurodollar
Borrowing the Administrative Agent shall have determined (i) that dollar deposits in the principal amounts of the Eurodollar Advances comprising such Borrowing are not generally available in the London interbank market or (ii) that
reasonable means do not exist for ascertaining the Eurodollar Rate, the Administrative Agent shall, as soon as practicable thereafter, give telecopy notice of such determination to the Borrower and the Lenders. In the event of any such determination
under clause (i) or (ii) above, until the Administrative Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (x) any request by the Borrower for a Eurodollar
Borrowing pursuant to Section 2.03 shall be deemed to be a request for a Base Rate Borrowing and (y) each Eurodollar Advance then outstanding will automatically, on the last day of the then applicable Interest Period therefor, Convert into
a Base Rate Advance. In the event the Majority Lenders notify the Administrative Agent that the rates at which dollar deposits are being offered will not adequately and fairly reflect the cost to such Lenders of making or maintaining Eurodollar
Advances during any Interest Period, the Administrative Agent shall notify the Borrower of such notice and until the Majority Lenders shall have advised the Administrative Agent that the circumstances giving rise to such notice no longer exist,
(A) any request by the Borrower for a Eurodollar Borrowing shall be deemed a request for a Base Rate Borrowing and (B) each Eurodollar Advance then outstanding will automatically, on the last day of the then applicable Interest Period
therefor, Convert into a Base Rate Advance. Each determination by the Administrative Agent hereunder shall be made in good faith and shall be conclusive absent manifest error; provided that the Administrative Agent shall, upon request,
provide to the Borrower a certificate setting forth in reasonable detail the basis for such determination. 

Section 2.10. Termination and Reduction of Commitments. 

(a) The Commitments shall automatically terminate on the Termination Date. 

(b) Upon at least three Business Days’ prior irrevocable written notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce, the Commitments; provided, however, that (i) each partial reduction of the Commitments shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $5,000,000, (ii) no such termination or reduction shall be made that would reduce the aggregate Commitments to an amount (A) less than the Outstanding Credits on the date of such termination or reduction (after giving
effect to Section 2.11(b)) or (B) less than $25,000,000, unless the result of such termination or reduction referred to in this clause (B) is to reduce the aggregate Commitments to $0 and (iii) the definition of “LC
Committed Amount” set forth in Section 1.01 shall be deemed amended to reflect an LC Committed Amount equal to the aggregate Commitments following such reduction. The Administrative Agent shall advise the Lenders of any notice given
pursuant to this Section 2.10(b) and of each Lender’s portion of any such termination or reduction of the aggregate Commitments. 
 (c) Each reduction in the Commitments hereunder shall be made ratably among the Lenders in accordance with their respective Commitments. Once terminated, a Commitment

  
 35 

 
may not be reinstated. The Borrower shall pay to the Administrative Agent for the account of the Lenders, on the date of each termination or reduction of the Commitments, the fees payable on the
Commitments under Section 2.05 so terminated or reduced accrued through the date of such termination or reduction. 

Section 2.11. Prepayment. 
 (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon giving telecopy notice (or telephone notice promptly confirmed by telecopy) to
the Administrative Agent: (i) before 10:00 A.M. three Business Days prior to prepayment, in the case of Eurodollar Advances, and (ii) before 10:00 A.M. one Business Day prior to prepayment, in the case of Base Rate Advances; provided,
however, that each partial prepayment shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000. 
 (b) If at any time (i) the aggregate Outstanding Credits exceed the aggregate Commitments or (ii) the aggregate LC Outstandings exceed the LC Committed Amount, the Borrower shall pay or prepay
so much of the Borrowings and/or deposit funds in the Cash Collateral Account in respect of undrawn Letters of Credit outstanding on such date, as applicable, as shall be necessary in order that the Outstanding Credits will not exceed the
Commitments and the LC Outstandings will not exceed the LC Committed Amount. 
 (c) Each notice of prepayment shall specify the
prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such Borrowing (or portion thereof) by the amount stated therein on the date stated therein.
All prepayments under this Section 2.11 shall be subject to Section 9.05(b) but otherwise without premium or penalty. All prepayments under this Section 2.11 shall be accompanied by accrued interest on the principal amount being
prepaid to the date of payment. 
 Section 2.12. Reserve Requirements; Change in Circumstances. 

(a) Notwithstanding any other provision herein, if after the Original Agreement Date the enactment of any new law or regulation, or any
change in applicable existing law or regulation, or in the interpretation or administration of the foregoing by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law), including,
without limitation, all requests, rules, guidelines or directives in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act regardless of the date enacted, adopted or issued, shall change the basis of taxation of payments to
any Lender hereunder (except for changes in respect of (i) Indemnified Taxes, (ii) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (iii) Connection Income Taxes), or shall result in the
imposition, modification or applicability of any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender, or shall result in the imposition on any Lender or the London
interbank market of any other condition affecting this Agreement, such Lender’s Commitment or any Extension of Credit made by such Lender, and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Extension of Credit or to reduce the amount of any sum 

  
 36 

 
received or receivable by such Lender hereunder (whether of principal, interest or otherwise) by an amount deemed in good faith by such Lender to be material, then the Borrower shall, upon
receipt of the notice and certificate provided for in Section 2.12(c), promptly pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 

(b) If any Lender shall have determined that the adoption after the Original Agreement Date of any law, rule, regulation or guideline
promulgated by the Bank for International Settlements, the Basel Committee on Banking Regulations and Supervisory Practices (or any successor or similar authority) or the United States financial regulatory authorities or the adoption after the
Original Agreement Date of any other law, rule, regulation or guideline regarding capital adequacy, or any change in any of the foregoing or in the interpretation or administration of any of the foregoing by any Governmental Authority, central bank
or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or any lending office of such Lender) or any Lender’s holding company with any request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central bank or comparable agency, has the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence
of this Agreement, such Lender’s Commitment or the Extensions of Credit made by such Lender pursuant hereto to a level below that which such Lender or such Lender’s holding company could have achieved but for such adoption, change or
compliance (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount deemed in good faith by such Lender to be material, then from time to time such
additional amount or amounts as will compensate such Lender for any such reduction suffered will be paid by the Borrower to such Lender. For the avoidance of doubt, this Section 2.12(b) shall apply to all requests, rules, guidelines or
directives concerning capital adequacy issued in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives concerning capital adequacy. 

(c) A certificate of each Lender setting forth such amount or amounts as shall be necessary to compensate such Lender or its holding
company as specified in subsection (a) or (b) above, as the case may be, and containing an explanation in reasonable detail of the manner in which such amount or amounts shall have been determined, shall be delivered to the Borrower and
shall be conclusive absent manifest error. The Borrower shall pay each Lender the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same. Each Lender shall give prompt notice to the Borrower of any
event of which it has knowledge, occurring after the Original Agreement Date, that it has determined will require compensation by the Borrower pursuant to this Section 2.12. If any such law, rule, regulation, guideline or other change or
condition described in this Section 2.12 shall later be held by a court of competent jurisdiction to be invalid or inapplicable to the Borrower or such Lender, such Lender shall promptly refund to the Borrower any amounts previously paid by the
Borrower to such Lender pursuant to this Section 2.12. 
 (d) Failure on the part of any Lender to demand compensation for
any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to any period shall not constitute a waiver of such Lender’s right to demand compensation with

  
 37 

 
respect to such period or any other period; provided that such Lender shall not be entitled to demand compensation hereunder if such demand is made more than 90 days following the later of
such Lender’s incurrence or sufferance thereof and such Lender’s actual knowledge of the event giving rise to such Lender’s rights under this Section. The protection of this Section shall be available to each Lender regardless of any
possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition that shall have occurred or been imposed. 
 (e) Each Lender agrees that it will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of
such Lender, be disadvantageous to such Lender. 
 Section 2.13. Change in Legality. 

(a) Notwithstanding any other provision herein, if the introduction of, or any change in, any law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Advance or to give effect to its obligations as contemplated hereby with respect
to any Eurodollar Advance, then, by written notice to the Borrower and to the Administrative Agent, such Lender may: 
 (i)
declare that Eurodollar Advances will not thereafter be made by such Lender hereunder, whereupon any request for a Eurodollar Borrowing shall, as to such Lender only, be deemed a request for a Base Rate Advance unless such declaration shall be
subsequently withdrawn (any Lender delivering such a declaration hereby agreeing to withdraw such declaration promptly upon determining that such event of illegality no longer exists); and 

(ii) require that all outstanding Eurodollar Advances made by it be Converted to Base Rate Advances, in which event all such Eurodollar
Advances shall be automatically Converted to Base Rate Advances as of the effective date of such notice as provided in subsection (b) below. 
 Prior to any Lender giving notice to the Borrower under this Section 2.13, such Lender shall use reasonable efforts to change the jurisdiction of its Applicable Lending Office, if such change would
avoid such event of illegality and would not, in the sole reasonable determination of such Lender, be otherwise disadvantageous to such Lender. In the event any Lender shall exercise its rights under (i) or (ii) above, all payments and
prepayments of principal that would otherwise have been applied to repay the Eurodollar Advances that would have been made by such Lender or the Converted Eurodollar Advances of such Lender shall instead be applied to repay the Base Rate Advances
made by such Lender in lieu of, or resulting from the Conversion of, such Eurodollar Advances. 
 (b) For purposes of this
Section 2.13, a notice by any Lender shall be effective as to each Eurodollar Advance, if lawful, on the last day of the Interest Period currently applicable to such Eurodollar Advance; in all other cases such notice shall be effective on the
date of receipt. 

  
 38 

 Section 2.14. Pro Rata Treatment. 

Except as required under Section 2.07(e), 2.12, 2.13, 2.17 or 9.15, each Borrowing, each payment or prepayment of principal of any
Borrowing, each payment of interest on the Advances, each payment of facility fees and Letter of Credit Fees, each reduction of the Commitments and each Conversion of any Advance by the Borrower shall be allocated pro rata among the Lenders in
accordance with their respective Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective Outstanding Credits of the Lenders); provided further, that the provisions of this Section shall
not be construed to apply to any payment made by or on behalf of the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender). For purposes
of determining the available or used Commitments at any time, the LC Outstandings shall be deemed to have utilized the Commitments of the Lenders pro rata in accordance with their respective Commitments. Each Lender agrees that in computing such
Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount. Notwithstanding the foregoing, in
connection with an extension of the Termination Date described in the last proviso in the first sentence of Section 9.08(b), this Agreement may provide for an increase in or otherwise different fees, margins and other amounts payable to the
extending Lenders relative to the amounts payable to Lenders that do not consent to the extension. 
 Section 2.15.
Sharing of Setoffs. 
 Each Lender agrees that if it shall, through the exercise of a right of banker’s lien,
setoff or counterclaim, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Extension of Credit, in any case as a result of which the unpaid principal portion of its Extensions of
Credit shall be proportionately less than the unpaid principal portion of the Extensions of Credit of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other
Lender the purchase price for, a participation in the Extensions of Credit of such other Lender, so that the aggregate unpaid principal amount of the Extensions of Credit and participations in the Extensions of Credit held by each Lender shall be in
the same proportion to the aggregate unpaid principal amount of all Extensions of Credit then outstanding as the principal amount of its Extensions of Credit prior to such exercise of banker’s lien, setoff or counterclaim or other event was to
the principal amount of all Extensions of Credit outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that, (i) if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.15 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored
without interest and (ii) the provisions of this Section shall not be construed to apply to (x) any payment made by or on behalf of the Borrower pursuant to and in accordance with the express terms of this Agreement (including the
application of funds arising from the existence of a Defaulting Lender), (y) the application of cash collateral provided for in Section 7.02, or (z) any payment obtained by a Lender as

  
 39 

 
consideration for the assignment of or sale of a participation in any of its Commitment, including pursuant to Section 2.18. The Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in an Extension of Credit deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such
Lender by reason thereof as fully as if such Lender had made an Extension of Credit in the amount of such participation. 

Section 2.16. Payments. 
 (a) The Borrower shall make each payment (including principal of or interest on any Borrowing, any fees, any reimbursements in respect of Letters of Credit that have been paid by any Lender or other
amounts) hereunder without setoff, counterclaim, defense, recoupment or other deduction from an account in the United States not later than 12:00 noon on the date when due in dollars to the Administrative Agent at its offices specified in
Section 9.01, in immediately available funds. 
 (b) Whenever any payment (including principal of or interest on any
Borrowing, any fees, any reimbursements in respect of Letters of Credit that have been paid by any Lender or other amounts) hereunder shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the
next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or fees, if applicable. 
 Section 2.17. Taxes. 
 (a) For purposes of this
Section 2.17, the term “Lender” includes any LC Bank and the Swingline Lender. 
 (b) Any and all payments by or
on account of any obligation of any Loan Party under any Credit 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 the applicable Loan Party 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) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or
withholding been made. 
 (c) The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with
applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. 
 (d) The
Loan Parties shall jointly and severally indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this
Section) payable or 

  
 40 

 
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 the Borrower by a Lender (with a copy to the Administrative Agent), or
by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 
 (e) Each
Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the
Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.04 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 Administrative Agent in connection with any Credit 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 by the
Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Credit Document or otherwise payable by the
Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this subsection (e). 
 (f) As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 2.17, such Loan Party shall deliver to the Administrative 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 Administrative Agent. 

(g) (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Credit
Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or
the Administrative 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 Borrower or the Administrative Agent, shall deliver such other
documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative 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 2.17(g)(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. 

  
 41 

 (ii) Without limiting the generality of the foregoing, in the event that the Borrower is a
U.S. Person, 
 (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to
the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt
from U.S. federal backup withholding tax; 
 (B) any Foreign Lender shall, to the extent it is legally entitled to do so,
deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon
the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable: 

(i) in the case of a Foreign 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 Credit Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax
treaty and (y) with respect to any other applicable payments under any Credit Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other
income” article of such tax treaty; 
 (ii) executed originals of IRS Form W-8ECI; 

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under
Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit K-1 to the effect that such Foreign 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 
 (iv) to the extent a Foreign
Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit K-2 or Exhibit K-3, IRS Form W-9, and/or other
certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such
Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit K-4 on behalf of each such direct and indirect partner; 

  
 42 

 (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the
Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable
request of the Borrower or the Administrative 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 Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and 

(D) if a payment made to a Lender under any Credit 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 the Borrower and the Administrative Agent at
the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative 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 the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative 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 the
Amendment and Restatement 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 Administrative Agent in writing of its legal inability to do so. 

(h) 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 2.17 (including by the payment of additional amounts pursuant to this Section 2.17), 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 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 subsection (h) (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 subsection (h), in no event will the
indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection (h) 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 subsection shall not be construed 

  
 43 

 
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.

 (i) Each party’s obligations under this Section 2.17 shall survive the resignation or replacement of the
Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document. 

Section 2.18. Assignment of Commitments Under Certain Circumstances. 

In the event that any Lender shall have delivered a notice or certificate pursuant to Section 2.12 or 2.13, or the Borrower shall be
required to make additional payments to any Lender under Section 2.09 or 2.17, or any Lender shall be a Defaulting Lender, or any Lender shall not consent to an amendment that requires the consent of such Lender and to which the Majority
Lenders have consented, the Borrower shall have the right, at its own expense, upon notice to such Lender, to require such Lender to transfer and assign without recourse (in accordance with and subject to the restrictions contained in
Section 9.04) all such Lender’s interests, rights and obligations under this Agreement and the other Credit Documents including without limitation in all interests in outstanding Letters of Credit, to another Eligible Assignee identified
by the Borrower and approved by the Administrative Agent, the Swingline Lender and each LC Bank to the extent required for assignments under Section 9.04(b), which financial institution shall assume such obligations of such Lender for
consideration equal to the outstanding principal amount of such Lender’s Advances, and if satisfactory arrangements are made for the payment to such Lender of interest and fees accrued hereunder to the date of such transfer and all other
amounts payable hereunder to such Lender on or prior to the date of such transfer, including, without limitation, amounts payable under Section 9.05(b); provided that (i) no such assignment shall conflict with any law, rule or
regulation or order of any Governmental Authority, (ii) the assignee or the Borrower, as the case may be, shall pay to the assignor in immediately available funds on or prior to the date of such assignment the principal of and interest accrued
to the date of payment on the Extensions of Credit made by such assignor hereunder and all other amounts accrued for its account or owed to it hereunder and (iii), if the assignee is not a Lender prior to such assignment, the Borrower shall have
paid to the Administrative Agent an administrative fee of $3,500 on or prior to the date of such assignment.

respect to this Guaranty, a separate action or actions may be brought and prosecuted against Exelon whether or not the Borrower is joined therein or a separate action or actions are brought against the Borrower. All remedies of the Credit Parties
are cumulative.

(c) any right to assert against any Credit Party, as a defense, counterclaim, set-off, recoupment or cross claim in respect of the
Guaranteed Obligations, any defense (legal or equitable) or other claim that Exelon may now or at any time hereafter have against the Borrower or any other Person (other than payment of the Obligations in full); 

(d) any defense based upon an election of remedies by any Credit Party, unless the same would excuse performance by the Borrower under

regarding the Borrower or its ability to perform under the Credit Documents. 
 Section 6.06. Limitation of Guaranty.

conveyance or fraudulent transfer (including the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act and Section 548 of title 11 of the United States Code or any applicable provisions of comparable requirements of law).

 Section 6.07. Termination. 

This Guaranty shall constitute a continuing guaranty and shall continue in full force and effect until such time as the Guaranteed
Obligations (other than contingent indemnity obligations) shall have been fully paid or otherwise extinguished under the Credit Documents; provided, that this Guaranty and all of this Article 6 shall automatically terminate and be of no
further force and effect immediately upon the merger of the Borrower into Exelon in accordance with Section 5.02(b). 

Section 6.08. Reliance. 
 Exelon hereby assumes responsibility for keeping itself informed of the financial condition of the Borrower and any other guarantor, maker or endorser of any Guaranteed Obligation or any part thereof, and
of all other circumstances bearing upon the risk of nonpayment of any Guaranteed Obligation or any part thereof that diligent inquiry would reveal, and Exelon hereby agrees that no Credit Party shall have any duty to advise Exelon of information
known to it regarding such condition or any such circumstances. In the event any Credit Party, in its sole discretion, undertakes at any time or from time to time to provide any such information to Exelon, such Credit Party shall be under no
obligation to (i) undertake any investigation not a part of its regular business routine, (ii) disclose any information that such Credit Party, pursuant to accepted (iii) make any future disclosures of such information or any other
information to Exelon.

(B) shall at the request, or may with the consent, of the Majority Lenders, by notice to the Borrower, declare the Advances, all interest thereon and all other amounts payable by the Borrower under this Agreement to be forthwith due and
payable, whereupon the Advances, all such interest and all such amounts shall become and be immediately due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower;
(ii) any LC Bank may issue a notice to the Borrower for and in accordance with each outstanding Letter of Credit providing that such LC Bank’s obligations under each such Letter of Credit shall terminate on the fifth Business Day following
the delivery of such notice; (iii) the Administrative Agent, for the account of the applicable LC Bank, may, by notice to the Borrower, give notice of the occurrence of an Event of Default to the Trustee for each series of Bonds supported by a
Bond Letter of Credit and instruct such Trustee either to accelerate such Bonds, thereby causing such 

  
 61 

 
Bond Letter of Credit to expire thereafter, per the terms of such Bond Letter of Credit, or to effect a mandatory tender of such Bonds and (iv) the Administrative Agent, for the account of
the applicable LC Bank, may exercise any other rights or remedies it may have under the Related Documents executed and delivered in connection with any Bond Letter of Credit. Notwithstanding anything in this Section 7.02 to the contrary, an
Event of Default under any of (x) subsection (h) or (i) of Section 7.01, or (y) subsection (c) of Section 7.01 resulting from a breach of Section 5.01(c) or Section 5.02(g), (h), (i) or (j) or
Section 5.01(a) (solely with respect to notices relating to a breach of any of the foregoing specified sections of this Agreement) shall not constitute an Event of Default for any purpose of this Agreement except for the purpose of exercising
the remedies described in clauses (iii) and (iv) of this Section 7.02(a) and shall not give the Administrative Agent the right to exercise any other remedy described in this Section 7.02(a), unless the facts and circumstances
underlying such Event of Default give rise to another Event of Default otherwise described in Section 7.01. If any Event of Default described in subsection (e) of Section 7.01 with respect to the Borrower shall occur and be
continuing, then (A) the obligation of each Lender to make Advances, the obligation of the Swingline Lender to make Swingline Advances and the obligation of the LC Banks to issue Letters of Credit shall automatically immediately terminate and
(B) the Advances, all interest thereon and all other amounts payable by the Borrower under this Agreement shall automatically become and be due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower. 
 (b) Cash Collateral Account. Notwithstanding anything to the contrary
contained herein, no notice given or declaration made by the Administrative Agent pursuant to this Section 7.02 shall affect the obligation of the LC Banks to make any payment under any Letter of Credit in accordance with the terms of such
Letter of Credit; provided, however, that (i) upon the occurrence and during the continuance of any Event of Default, the Administrative Agent shall at the request, or may with the consent, of the Majority Lenders, upon notice to the
Borrower, require the Borrower to deposit with the Administrative Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below equal to the aggregate maximum amount available to be drawn
under all Letters of Credit outstanding at such time and (ii) at any time that there shall exist a Defaulting Lender, promptly upon (and in any case within 2 Business Days after) the request of the Administrative Agent, any LC Bank or the
Swingline Lender, the Borrower shall deposit with the Administrative Agent an amount in the Cash Collateral Account equal to an amount sufficient to cover all Fronting Exposure (after giving effect to Section 9.15(a)(iv) and any cash collateral
provided by the Defaulting Lender). Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Administrative Agent in the name of, and under
the sole dominion and control of, the Administrative Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by Bank of America for deposits equal to the amount deposited by the
Borrower in the Cash Collateral Account, for a term to be determined by the Administrative Agent in its sole discretion. The Borrower hereby grants to the Administrative Agent for the benefit of the Lenders and the LC Banks a Lien on, and hereby
assigns to the Administrative Agent for the benefit of the Lenders and the LC Banks all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in
respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any

  
 62 

 
such event, the Administrative Agent may, and, upon the Borrower’s request, shall, apply the amounts then on deposit in the Cash Collateral Account, in such priority as the Administrative
Agent shall elect, toward the payment in full of any or all of the Borrower’s obligations hereunder as and when such obligations shall become due and payable. Upon payment in full, after the termination of the Letters of Credit, of all such
obligations, the Administrative Agent will repay and reassign to the Borrower any cash then on deposit in the Cash Collateral Account and the Lien of the Administrative Agent on the Cash Collateral Account and the funds therein shall automatically
terminate. Any cash deposited in the Cash Collateral Account provided to reduce Fronting Exposure or other cash collateralization obligations in relation to a Defaulting Lender shall be released promptly following (i) the elimination of the
applicable Fronting Exposure or such other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender, in the appropriate portion of such deposited cash, or (ii) the Administrative
Agent’s good faith determination that there exists excess cash collateral, in the amount of such excess; provided, however, (x) that cash collateral furnished by or on behalf of the Borrower shall not be released during the
continuance of an Event of Default, and (y) the Person providing cash collateral and each relevant LC Bank or Swingline Lender, as applicable, may agree that cash collateral shall not be released but instead held to support future anticipated
Fronting Exposure or such other obligations. 
 ARTICLE VIII 

THE ADMINISTRATIVE AGENT 
 Section 8.01. Appointment and Authority. 
 Each Lender and LC
Bank hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent hereunder and under the other Credit Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers
as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Except as expressly set forth in Section 8.06, the provisions of this Article are solely
for the benefit of the Administrative Agent, the Lenders and the LC Banks, and the Borrower and Exelon shall not have rights as a third party beneficiary of any of such provisions. 

Section 8.02. Rights as a Lender. 
 The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the
Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual
capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Exelon, the Borrower or any Subsidiary of any Loan
Party or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders. 

  
 63 

 Section 8.03. Exculpatory Provisions. 

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Credit
Documents. Without limiting the generality of the foregoing, the Administrative Agent: 
 (a) shall not be
subject to any fiduciary or other implied duties, regardless of whether an Unmatured Event of Default has occurred and is continuing; 
 (b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents
that the Administrative Agent is required to exercise as directed in writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit Documents), provided that
the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Credit Document or applicable law; and 

(c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

 The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the
request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.08 and 7.02)
or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Unmatured Event of Default unless and until notice describing such Unmatured Event of Default is
given to the Administrative Agent by Exelon, the Borrower, a Lender or an LC Bank. 
 The Administrative Agent shall not be
responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other
document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any
Unmatured Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in
Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 
 Section 8.04. Reliance by Administrative Agent. 
 The
Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or 

  
 64 

 
other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated
by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining
compliance with any condition hereunder to the making of an Advance, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an LC Bank, the Administrative Agent may presume that such condition
is satisfactory to such Lender or LC Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or LC Bank prior to the making of such Advance or the issuance of such Letter of Credit. The Administrative Agent
may consult with legal counsel (who may be counsel for Exelon or the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts. 
 Section 8.05. Delegation of Duties. 

The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit
Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective
Affiliates. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication
of the credit facilities provided for herein as well as activities as Administrative Agent. 
 Section 8.06.
Resignation of Administrative Agent. 
 (a) The Administrative Agent may at any time give notice of its resignation to
the Lenders, the LC Banks and the Borrower. Upon receipt of any such notice of resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United
States, or an Affiliate of any such bank with an office in the United States that is acceptable to the Borrower as long as no Event of Default has occurred and is continuing. If no such successor shall have been so appointed by the Majority Lenders
(and accepted by the Borrower) and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the LC
Banks, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such
resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents and (2) all
payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and each LC Bank directly, until such time as the Majority Lenders appoint a successor
Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and
duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent 

  
 65 

 
shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this Section). After the
retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article and Section 9.05 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent. 

(b) Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also constitute its resignation as the
Swingline Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the Swingline Lender, and
(ii) the Swingline Lender shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents. 
 Section 8.07. Non-Reliance on Administrative Agent and Other Lenders. 
 Each Lender and LC Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and
information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each of the Lenders and LC Banks also acknowledges that it will, independently and without reliance upon the Administrative Agent or
any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any
other Credit Document or any related agreement or any document furnished hereunder or thereunder. 
 Section 8.08. No
Other Duties, Etc. 
 Anything herein to the contrary notwithstanding, (i) none of the Joint Lead Arrangers and

Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall
cease to be a party to 

  
 68 

 
this Agreement (but shall continue to be entitled to the benefits of Sections 2.12 and 9.05 afforded to such Lender prior to its assignment as well as to any fees accrued for its account
hereunder and not yet paid)). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with provision (b)(viii) of this Section shall be treated for purposes of this Agreement as a sale by such Lender
of a participation in such rights and obligations in accordance with subsection (f) of this Section. 
 (c) By executing
and delivering an Assignment and Assumption, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it
is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, (ii) except as set forth in (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document
furnished pursuant thereto or the financial condition of the Borrower or the performance or observance by the Borrower of any obligations under this Agreement or any other instrument or document furnished pursuant thereto; (iii) such assignor
and such assignee represents and warrants that it is legally authorized to enter into such Assignment and Assumption; (iv) such assignee confirms that it has received copies of this Agreement, together with copies of the most recent financial
statements delivered pursuant to Section 5.03 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (v) such assignee will
independently and without reliance upon the Administrative Agent, such assigning Lender 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; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent
by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement are required to be
performed by it as a Lender. 
 (d) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall
maintain at one of its offices in the United States 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 Commitments of, and the principal amount of
Outstanding Credits (and stated interest) 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 Borrower, the
Administrative Agent and the Lenders shall 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. The Register shall be available for inspection by the Borrower
and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 
 (e) Upon its receipt of a duly
completed Assignment and Assumption executed by an assigning Lender and an assignee, the processing and recordation fee referred to in subsection (b) above and, if required, the written consent of the Borrower, the Administrative Agent to such

  
 69 

 
assignment, the Administrative Agent shall (i) accept such Assignment and Assumption and (ii) record the information contained therein in the Register. 

(f) Each Lender may without the consent of the Borrower or the Administrative Agent sell participations to one or more banks or entities
(other than the Borrower, the Borrower’s Affiliates, the Borrower’s Subsidiaries, a Defaulting Lender or any natural person) in all or a portion of its rights and/or obligations under this Agreement (including all or a portion of its
Commitment and the Outstanding Credits owing to it); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties to
this Agreement for the performance of such obligations, (iii) each participating bank or other entity shall be entitled to the benefit of the cost protection provisions contained in Sections 2.12 and 9.05 and of the tax provision contained in
Section 2.17 to the same extent as if it were the selling Lender (and limited to the amount that could have been claimed by the selling Lender had it continued to hold the interest of such participating bank or other entity, unless the sale of
the participation is made with the Borrower’s prior written consent), except that all claims made pursuant to such Sections shall be made through such selling Lender, (iv) if a participant would be a Foreign Lender if it were a Lender,
such participant shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such participant and such participant agrees, for the benefit of the Borrower, to comply with
Section 2.17(f) as though it were a Lender, and (v) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such selling Lender in connection with such Lender’s rights and
obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower under this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers (x) decreasing any fees payable hereunder or the amount of principal of, or the rate at which interest is payable on, the Outstanding Credits, (y) extending any principal payment date or date fixed for
the payment of interest on the Outstanding Credits or (z) extending the Commitments). Such participations shall not create any “security” (as the word “security” is defined under the Securities Act of 1933, as amended) of
the Borrower. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each participating bank or other entity and the
principal amounts (and stated interest) of each participating bank or other entity’s interest in the Outstanding Credits or other obligations under the Credit Documents (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 participating bank or other entity or any information relating to a participating bank or other entity ‘s interest in
any commitments, loans, letters of credit or its other obligations under any Credit 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 this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no
responsibility for maintaining a Participant Register. 

  
 70 

 (g) Any Lender or participant may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section, disclose to the assignee or participant or proposed assignee or participant any information relating to any Loan Party furnished to such Lender by or on behalf of such Loan Party;
provided that, prior to any such disclosure, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the
confidentiality of any such information. 
 (h) Any Lender may at any time pledge all or any portion of its rights under this
Agreement to a Federal Reserve Bank; provided that no such pledge shall release any Lender from its obligations hereunder or substitute any such Bank for such Lender as a party hereto. In order to facilitate such an assignment to a Federal
Reserve Bank, the Borrower shall, at the request of the assigning Lender, duly execute and deliver to the assigning Lender a promissory note or notes evidencing the Advances made to the Borrower by the assigning Lender hereunder. 

Section 9.05. Expenses; Indemnity. 
 (a) The Borrower agrees to pay all reasonable out-of-pocket expenses incurred by the Administrative Agent, including, without limitation, the reasonable fees, charges and disbursements of one outside
counsel for the Administrative Agent and its Affiliates (and, to the extent necessary, one additional local counsel in any relevant jurisdiction), in connection with entering into this Agreement and the other Credit Documents and in connection with
any amendments, modifications or waivers of the provisions thereof (whether or not the transactions hereby contemplated are consummated), and all reasonable out-of-pocket expenses, including, without limitation, the reasonable fees, charges and
disbursements of counsel, incurred by the Administrative Agent, the Swingline Lender, any LC Bank or any Lender in connection with the enforcement or protection of their rights in connection with the Credit Documents or in connection with the
Extensions of Credit made hereunder. 
 (b) The Borrower agrees to indemnify each Lender against any actual loss, calculated in
accordance with the next sentence that such Lender may incur as a consequence of (i) any failure by the Borrower to borrow or to Convert any Eurodollar Advance hereunder (including as a result of the Borrower’s failure to fulfill any of
the applicable conditions set forth in Article III) after irrevocable notice of such borrowing or Conversion has been given pursuant to Section 2.03, (ii) any payment or prepayment of a Eurodollar Advance by the Borrower made or deemed
made on a date other than the last day of the Interest Period, if any, applicable thereto, including as a result of an Event of Default, (iii) any default in payment or prepayment of the principal amount of any Eurodollar Advance or interest
accrued thereon, as and when due and payable (at the due date thereof, whether by scheduled maturity or otherwise), or (iv) any assignment of a Eurodollar Advance made at the request of the Borrower pursuant to Section 2.18 on a date other
than the last day of the Interest Period applicable thereto, including, in each such case, any loss or reasonable expense incurred or to be incurred by such Lender in liquidating or employing deposits from third parties, or with respect to
commitments made or obligations undertaken with third parties, to effect or maintain any Advance hereunder or any part thereof as a Eurodollar Advance. Such loss shall include an amount equal to the excess, if any, as reasonably determined by such
Lender, of (i) its cost of obtaining the funds for the Advance being paid, prepaid, not borrowed or Converted or assigned (assumed to be the Eurodollar Rate applicable 

  
 71 

 
thereto) for the period from the date of such payment, prepayment, failure to borrow or Convert or assignment to the last day of the Interest Period for such Extension of Credit (or, in the case
of a failure to borrow or Convert the Interest Period for such Extension of Credit that would have commenced on the date of such failure) over (ii) the amount of interest at the Eurodollar Rate for the relevant remaining interest period (as
reasonably determined by such Lender) that would be realized by such Lender in re-employing the funds so paid, prepaid, not borrowed or Converted or assigned for such period or Interest Period, as the case may be, but excluding any anticipated
profit. This Section 9.05(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim. 
 (c) The Borrower agrees to indemnify the Administrative Agent, the Swingline Lender, the LC Banks, each Lender, each of their Affiliates (including, in the case of Bank of America, Banc of America
Securities LLC) and the directors, officers, employees, advisors, attorneys-in-fact and agents of the foregoing (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all
actual losses, claims, damages, liabilities and related reasonable out-of-pocket costs and expenses, including reasonable counsel fees and expenses, incurred by any Indemnitee arising out of (i) the consummation of the transactions contemplated
by this Agreement, (ii) the use of the proceeds of the Extensions of Credit, (iii) any documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement, (iv) the
utilization, storage, disposal, treatment, generation, transportation, release or ownership of any Hazardous Substance (A) at, upon, or under any property of the Borrower or any of its Affiliates or (B) by or on behalf of the Borrower or
any of its Affiliates at any time and in any place, or (v) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto, including any of the foregoing arising from the
negligence, whether sole or concurrent, on the part of any Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined
by a final judgment of a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee; provided, further, that the Borrower agrees that it will not, nor will it permit any
Subsidiary to, without the prior written consent of each Indemnitee named in such settlement as set forth below (such consent not to be unreasonably withheld), settle, compromise or consent to the entry of any judgment in any pending or threatened
claim, action, suit or proceeding in respect of which indemnification could be sought under the indemnification provisions of this Section 9.05(c) (whether or not any Indemnitee is an actual or potential party to such claim, action, suit or
proceeding), if such settlement, compromise or consent includes any statement as to an admission of fault, culpability or failure to act by or on behalf of any Indemnitee or involves any payment of money or other value by any Indemnitee or any
injunctive relief or factual findings or stipulations binding on any Indemnitee. 
 (d) The provisions of this Section shall
remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the termination of the Commitments, the repayment of any of the Outstanding Credits,
the invalidity or unenforceability of any term or provision of this Agreement or any investigation made by or on behalf of the Administrative Agent or any Lender. All amounts due under this Section shall be payable on written demand therefor.

  
 72 

 (e) Ten Business Days prior to the date on which any amount or amounts due under this
Section are payable in accordance with a demand from a Lender or the Administrative Agent for such amount or amounts, such Lender or the Administrative Agent will cause to be delivered to the Borrower a certificate, which shall be conclusive absent
manifest error, setting forth any amount or amounts that such person is entitled to receive pursuant to subsection (b) of this Section and containing an explanation in reasonable detail of the manner in which such amount or amounts shall have
been determined. 
 (f) To the extent permitted by applicable law, none of the parties hereto shall assert, and each hereby
waives, any claim against any Indemnitee or any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of,
this Agreement or any other Credit Document, the transactions contemplated herein or therein, any Extension of Credit or the use of proceeds thereof. 
 Section 9.06. Right of Setoff. 
 If (i) an Event of
Default shall have occurred and be continuing and (ii) the request shall have been made or the consent granted by the Majority Lenders as specified by Section 7.02 to authorize the Administrative Agent to declare the Extensions of Credit
of the Borrower due and payable pursuant to the provisions of Section 7.02, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of any Loan Party against any of and all the obligations of such Loan Party under this
Agreement, irrespective of whether or not such Lender shall have made any demand under this Agreement, and although such obligations may be unmatured; provided, that in the event that any Defaulting Lender shall exercise any such right of
setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 9.15 and, pending such payment, shall be segregated by such Defaulting
Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the
obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

 Section 9.07. Applicable Law. 
 THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 
 Section 9.08. Waivers; Amendment. 
 (a) No failure or delay of
the Administrative Agent or any Lender in exercising any power or right under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or the exercise of 

  
 73 

 
any other right or power. The rights and remedies of the Administrative Agent and the Lenders under this Agreement are cumulative and are not exclusive of any rights or remedies that they would
otherwise have. No waiver of any provision of this Agreement or consent to any departure therefrom shall in any event be effective unless the same shall be permitted by subsection (b) below, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice or demand on any Loan Party or any Subsidiary thereof in any case shall entitle such party to any other or further notice or demand in similar or other circumstances.

 (b) No provision of this Agreement may be waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by the Borrower, Exelon and the Majority Lenders (but only when notice thereof is delivered to the Administrative Agent in accordance with Section 9.01) or the Administrative Agent with the consent or at the direction of
the Majority Lenders; provided, however, that no such agreement shall (i) decrease the principal amount of, or extend the maturity of or any scheduled principal payment date or date for the payment of any interest on any Outstanding
Credit, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Outstanding Credit (other than pursuant to an amendment to or waiver of Section 2.08), without the prior written consent of each Lender
affected thereby, (ii) increase the Commitment of any Lender, decrease the fees owing to any Lender (except pursuant to Section 9.14) or postpone the payment of any fee owing to any Lender without the prior written consent of such Lender,
(iii) amend, waive or modify the provisions of Section 2.14, Section 2.15 or Section 9.04(h), the provisions of this Section or the definition of the “Majority Lenders”, without the prior written consent of each Lender,
(iv) release or permit the transfer of the obligations of any Loan Party hereunder (including Exelon’s obligations under Article VI) without the prior written consent of each Lender, except as permitted by Section 5.02(b) or
(v) change the definition of LC Committed Amount without the prior written consent of the applicable LC Bank (which consent shall not be unreasonably withheld); provided further, however, that no such agreement shall amend, modify
or otherwise affect the rights or duties of the Administrative Agent or the LC Bank hereunder without the prior written consent of the Administrative Agent or the LC Bank, as the case may be, provided, further that this Agreement may
be amended and restated without the consent of any Lender, any LC Bank, or the Administrative Agent if, upon giving effect to such amendment and restatement, such Lender, LC Bank or the Administrative Agent, as the case may be, shall no longer be a
party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender, such LC Bank or the Administrative Agent, as the case may be;
provided, further, that (i) the Termination Date with respect to any Lender’s Commitment may be extended with only the consent of the Lenders agreeing to such extension with respect to such Lender’s Commitment, and
(ii) any amendment to this Agreement to effectuate such extension, including the creation of separate tranches of Commitments with extended Termination Dates with different pricing and other terms, may be made with the consent of the Majority
Lenders. Each Lender shall be bound by any waiver, amendment or modification authorized by this Section and any consent by any Lender pursuant to this Section shall bind any assignee of its rights and interests hereunder. 

(c) Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment,
waiver or consent hereunder (and any 

  
 74 

 
amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting
Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected
Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender. 
 Section 9.09. ENTIRE AGREEMENT. 
 THIS AGREEMENT (INCLUDING THE
SCHEDULES AND EXHIBITS HERETO), THE NOTES, THE LETTERS OF CREDIT AND THE FEE LETTER (COLLECTIVELY, THE “AGREEMENT DOCUMENTS”) REPRESENT THE ENTIRE CONTRACT AMONG THE PARTIES RELATIVE TO THE SUBJECT MATTER HEREOF AND THEREOF.
ANY PREVIOUS AGREEMENT, WHETHER WRITTEN OR ORAL, AMONG THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF OR THEREOF IS SUPERSEDED BY THE AGREEMENT DOCUMENTS. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. NOTHING IN THIS AGREEMENT
OR THE FEE LETTERS, EXPRESSED OR IMPLIED, IS INTENDED TO CONFER UPON ANY PARTY OTHER THAN THE PARTIES HERETO AND THERETO ANY RIGHTS, REMEDIES, OBLIGATIONS OR LIABILITIES UNDER OR BY REASON OF THE AGREEMENT DOCUMENTS. 

Section 9.10. Severability. 
 In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable provisions. Without limiting the foregoing provisions of this Section 9.10, if and to the extent that the enforceability of any provisions in this Agreement relating to
Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, any LC Bank or the Swingline Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so
limited. 
 Section 9.11. Execution in Counterparts; Integration. 

This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when
so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes all prior and
contemporaneous agreements and understandings, oral or written, relating to the subject mater hereof.

Section 9.13. Jurisdiction; Venue; Waiver of Jury Trial. 

(a) Each Loan Party, the Administrative Agent, each LC Bank, the Swingline Lender and each Lender hereby irrevocably and unconditionally
submits to the nonexclusive jurisdiction of any Federal court, to the extent permitted by law, of the United States of America sitting in the borough of Manhattan in New York City or, if such Federal court is not available due to lack of
jurisdiction, any New York State court sitting in the borough of Manhattan in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any
judgment, and hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Federal Court, to the extent permitted by law, or in such New York State court. Each Loan
Party, the Administrative Agent, each LC Bank, the Swingline Lender and each Lender each agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any
other manner provided by law. Subject to the foregoing and to subsection (b) below, nothing in this Agreement shall affect any right that any party thereto may otherwise have to bring any action or proceeding relating to this Agreement against
any other party thereto in the courts of any jurisdiction. 
 (b) Each Loan Party, the Administrative Agent, each LC Bank, the
Swingline Lender and each Lender each hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or thereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any New York State or Federal court. Each Loan Party, the Administrative Agent, each LC Bank, the Swingline Lender and each Lender each hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (c)
EACH LOAN PARTY, THE ADMINISTRATIVE AGENT, THE SWINGLINE LENDER, EACH LENDER AND EACH LC BANK EACH HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON THIS AGREEMENT,
OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS OF ANY LOAN PARTY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT,
THE LENDERS, THE LC BANKS AND THE LOAN PARTIES ENTERING INTO THIS AGREEMENT.

 Section 9.14. Confidentiality; USA PATRIOT Act. 

(a) The Administrative Agent, each LC Bank, the Swingline Lender and each Lender shall hold in confidence all non-public, confidential or
proprietary information, memoranda, or extracts (collectively, “Information”) furnished to the Administrative Agent, such LC Bank, the Swingline Lender and such Lender (directly or through the Administrative Agent) by each
Loan Party under this Agreement or in connection with the negotiation thereof; provided that the Administrative Agent, such LC Bank, the Swingline Lender and such Lender may disclose any such Information (i) (A) to its directors,

any regulatory or supervisory authority having authority to examine the Administrative Agent, such LC Bank, the Swingline Lender, such Lender or such Lender’s Affiliates, (iii) as required by any legal or governmental process or otherwise
by law (with such Lender providing details, to the extent permitted by law, to such Loan Party of the Information disclosed pursuant to this clause (iii)), (iv) to any Person to which the Administrative Agent, such LC Bank, the Swingline Lender
or such Lender sells or proposes to sell an assignment or a participation in its Outstanding Credits hereunder, if such other Person agrees for the benefit of such Loan Party to comply with the provisions of this Section and (v) to the extent
that such Information shall be publicly available or shall have become known to the Administrative Agent, such LC Bank, the Swingline Lender or such Lender independently of any disclosure by such Loan Party under this Agreement or in connection with
the negotiation thereof. The Administrative Agent, any LC Bank, the Swingline Lender and any Lender disclosing Information pursuant to clause (i) or (iv) of this Section 9.13 will take reasonable steps to ensure that the persons
receiving such Information pursuant to such Sections will hold the same in confidence in accordance with this Section 9.13. To the extent possible, the Administrative Agent, any LC Bank, the Swingline Lender and any Lender disclosing
Information pursuant to clause (ii) or (iii) of this Section 9.13 will take reasonable steps to ensure that the persons receiving such Information pursuant to such Sections will hold the same in confidence in accordance with this
Section 9.13. 
 (b) Notwithstanding the foregoing, any Lender may disclose the provisions of this Agreement and the
amounts, maturities and interest rates of its Outstanding Credits to any purchaser or potential purchaser of such Lender’s interest in any Outstanding Credits. Notwithstanding anything to the contrary in this Agreement, each party hereto shall
not be limited from disclosing the US tax treatment or US tax structure of the transactions contemplated by this Agreement. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies each Loan Party that,
pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies each Loan Party,
which information includes the name and address of each Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify each Loan Party in accordance with the Act. Each Loan Party shall, promptly
following a request by the Administrative Agent or any Lender (made through the Administrative Agent), provide all documentation and other information that the Administrative Agent or such Lender (made through the Administrative Agent) reasonably

 Section 9.15. Defaulting Lenders. 

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting
Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable law: 
 (i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in
Section 9.08(c). 
 (ii) Reallocation of Payments. Any payment of principal, interest, fees or other
amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise, and including any amounts made available to the Administrative Agent by that
Defaulting Lender pursuant to Section 9.06), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative
Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the LC Banks or Swingline Lender hereunder; third, if so determined by the Administrative Agent or requested by the LC Banks
or Swingline Lender, to be held in the Cash Collateral Account, in accordance with the procedures set forth in Section 7.02, for future funding obligations of that Defaulting Lender of any participation in any Swingline Advance or Letter of
Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Advance in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as
determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in the Cash Collateral Account, and released in order to satisfy obligations of that Defaulting Lender to fund Advances
under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the LC Banks or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any LC Bank or Swingline Lender against
that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of
any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as
otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advance or Unreimbursed LC Disbursement in respect of which that Defaulting Lender has not fully
funded its appropriate share and (y) such Advance or Unreimbursed LC Disbursement was made at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and
Unreimbursed LC Disbursements owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Unreimbursed LC Disbursements owed to, that Defaulting Lender. Any payments, prepayments or other
amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral 

  
 78 

 
pursuant to this Section 9.14(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto. 

(iii) Certain Fees. That Defaulting Lender shall not be entitled to receive any Facility Fee in respect of such
Defaulting Lender’s Commitments not utilized by Advances or any Letter of Credit Fee pursuant to Section 2.05 for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that
otherwise would have been required to have been paid to that Defaulting Lender). 
 (iv) Reallocation of
Applicable Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in
Letters of Credit or Swingline Advances pursuant to Sections 2.03 and 2.04, the Commitment Percentage of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that,
(i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Unmatured Event of Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting
Lender to acquire, refinance or fund participations in Letters of Credit and Swingline Advances shall not exceed the positive difference, if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the sum of the
Outstanding Credits, Swingline Outstandings and LC Outstandings of that Lender. 
 (b) Defaulting Lender
Cure. If the Borrower, the Administrative Agent, the Swingline Lender and the LC Banks agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent
will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any cash collateral), that Lender will, to the extent
applicable, purchase that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit and
Swingline Advances to be held on a pro rata basis by the Lenders in accordance with their Commitment Percentages (without giving effect to Section 9.14(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no
adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed
by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. 

Section 9.16. No Advisory or Fiduciary Responsibility. 

In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other
modification hereof or of any other Credit Document), each Loan Party acknowledges and agrees that: (i) (A) the arranging and other services regarding this Agreement provided by the Administrative Agent, the Arrangers and the

  
 79 

 
Lenders are arm’s-length commercial transactions between such Loan Party and its Affiliates, on the one hand, and the Administrative Agent, the Arrangers and the Lenders, on the other hand,
(B) such Loan Party has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (C) such Loan Party is capable of evaluating, and understands and accepts, the terms, risks and
conditions of the transactions contemplated hereby and by the other Credit Documents; (ii) (A) the Administrative Agent, each Arranger and each Lender each is and has been acting solely as a principal and, except as expressly agreed in
writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for such Loan Party or any of its Affiliates, or any other Person and (B) neither the Administrative Agent nor any Arranger or
Lender has any obligation to such Loan Party or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Credit Documents; and (iii) the Administrative
Agent, the Arrangers and the Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of such Loan Party and its Affiliates, and neither the Administrative Agent nor any
Arranger or Lender has any obligation to disclose any of such interests to such Loan Party or its Affiliates. To the fullest extent permitted by law, each Loan Party hereby waives and releases any claims that it may have against the Administrative
Agent, the Arrangers and the Lenders with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby. 

Section 9.17. Electronic Execution of Assignments and Certain Other Documents. 

The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption or
in any amendment or other modification hereof (including waivers and consents) shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability
as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New
York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

that the rights and obligations of the Assignees hereunder are several and not joint.]2 Capitalized terms used but not defined herein shall have the meanings given to them in the Credit Agreement identified below (as amended, the “Credit Agreement”), receipt of a
copy of which is hereby acknowledged by [the][each] Assignee. The Standard Terms and Conditions set forth in Annex 1 attached hereto are hereby agreed to and incorporated herein by reference and made a part of this Assignment and Assumption as if
set forth herein in full. 
 For an agreed consideration, the Assignor hereby irrevocably sells and assigns to [the
Assignee][the respective Assignees], and [the][each] Assignee hereby irrevocably purchases and assumes from the Assignor, subject to and in accordance with the Standard Terms and Conditions and the Credit Agreement, as of the Effective Date inserted
by the Administrative Agent as contemplated below (i) all of the Assignor’s rights and obligations in its capacity as a Lender under the Credit Agreement and any other documents or instruments delivered pursuant thereto (collectively, the
“Credit Documents”) to the extent related to the amount and percentage interest identified below of all of such outstanding rights and obligations of the Assignor under the respective facilities identified below (including
without limitation any letters of credit or swingline loans included in such facilities) and (ii) to the extent permitted to be assigned under applicable law, all claims, suits, causes of action and any other right of the Assignor (in its

 (a) Except as specifically amended and
supplemented hereby, the Existing Credit Agreement shall remain in full force and effect to the extent in effect immediately prior to this Amendment and is hereby ratified and confirmed. 

(b) The execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or

(iii) the aggregate principal amount of the requested Advances and (iv) in the case of a borrowing of Eurodollar Advances, the initial Interest Period therefor. Each Lender shall, before 12:00 noon on the date of such borrowing, make
available for the account of its Applicable Lending Office to the 

  
 -15-

 
Administrative Agent at its address referred to in Section 8.02, in same day funds, such Lender’s ratable portion of the requested borrowing. After the Administrative
Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent’s aforesaid address.

 (b) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. If a Notice of Borrowing requests Eurodollar
Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure of the Borrower to fulfill on or before the requested borrowing date the applicable conditions set forth in

available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances made in connection with such borrowing and (ii) in the
case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this
Agreement. 
 (d) The failure of any Lender to make the Advance to be made by it on any borrowing date shall not relieve any
other Lender of its obligation, if any, hereunder to make its Advance on such date, but no Lender shall be responsible for the failure of any other Lender to make any Advance to be made by such other Lender.

Advance, a rate per annum equal to the sum of the Adjusted LIBO Rate for each applicable Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of each Interest Period for such Eurodollar Advance (and,
if any Interest Period for such Advance is six months, on the day that is three months after the first day of such Interest Period) or, if earlier, on the date such Eurodollar Advance is converted to a Base Rate Advance or paid in full and on such
Lender’s Termination Date (and, if applicable, thereafter on demand). 
 SECTION 2.07 Alternate Rate of
Interest. If prior to the commencement of any Interest Period for a Eurodollar Advance: 
 (a) the Administrative Agent
determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or 

(b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately
and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Advances (or its Advances) included in such Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the
Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any notice that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective and
(ii) if any Notice of Borrowing requests a Eurodollar Advance, such Advance shall be made as a Base Rate Advance.

 SECTION 2.08 Interest Rate Determination. 

(a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of each applicable interest rate determined by the
Administrative Agent for purposes of Section 2.06(a) or (b). 
 (b) If, with respect to any Borrowing of
Eurodollar Advances, the Majority Lenders notify the Administrative Agent that the Adjusted LIBO Rate for any Interest Period for such Advances will not adequately reflect the cost to such Majority Lenders of making, funding or maintaining their
respective Eurodollar Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon 
 (i) each Eurodollar Advance will automatically, on the last day of the then existing Interest Period therefor (unless prepaid or converted to a Base Rate Advance prior to such day), convert into a Base
Rate Advance, and 
 (ii) the obligation of the Lenders to make, continue or convert into Eurodollar Advances
shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. 
 SECTION 2.09 Continuation and Conversion of Advances. 
 (a) The
Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 10:00 A.M. on the third Business Day prior to the date of any proposed continuation of or conversion into Eurodollar Advances, and on the date of any
proposed conversion into Base Rate Advances, and subject to the provisions of Sections 2.08 and 2.12, continue Eurodollar Advances for a new Interest Period or convert a Borrowing of Advances of one Type into Advances of the other
Type; provided that any continuation of Eurodollar Advances or conversion of Eurodollar Advances into Base Rate Advances shall be made on, and only on, the last day of an Interest Period for such Eurodollar Advances, unless, in the case of
such a conversion, the Borrower shall also reimburse the Lenders pursuant to Section 8.04(b) on the date of such conversion. Each such notice of a continuation or conversion shall, within the restrictions specified above, specify
(i) the date of such continuation or conversion, (ii) the Advances to be continued or converted, and (iii) in the case of continuation of or conversion into Eurodollar Advances, the duration of the Interest Period for such Advances.

 (b) If the Borrower fails to select the Type of any Advance or the duration of any Interest Period for any Borrowing of
Eurodollar Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and Section 2.09(a), the Administrative Agent will forthwith so notify the Borrower and the
Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, convert into Base Rate Advances. 
 SECTION 2.10 Prepayments. The Borrower may, upon notice to the Administrative Agent not later than 10:00 A.M. at least three Business Days prior to any prepayment of Eurodollar Advances or on
the date of any prepayment of Base Rate Advances, in each case stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall, prepay the outstanding principal amounts of the Advances made
as part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided that (i) each partial prepayment shall be in an aggregate principal amount
not less than $10,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Eurodollar Advances and $5,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of

  
 -18-

 
Base Rate Advances (provided that if the aggregate amount of Advances made pursuant to Section 2.16 as a result of a drawing under a Facility LC is not $5,000,000 or a higher
integral multiple of $1,000,000, then the next prepayment of Base Rate Advances shall be in an aggregate amount that causes the aggregate principal amount of all Base Rate Advances to be either (A) zero or (B) $5,000,000 or a higher
integral multiple of $1,000,000) and (ii) in the case of any such prepayment of a Eurodollar Advance, the Borrower shall be obligated to reimburse the Lenders pursuant to Section 8.04(b) on the date of such prepayment. 

SECTION 2.11 Increased Costs. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with
or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any LC Issuer; 
 (ii) impose on any Lender or any LC Issuer or the London interbank market any other condition affecting this Agreement or Eurodollar Advances made by such Lender or any Facility LC or participation
therein; or 
 (iii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes and (B) Other
Connection Taxes on gross or net income, profits or revenue (including value-added or similar Taxes)) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital
attributable thereto; 
 and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making
or maintaining any Eurodollar Advance (or of maintaining its obligation to make any such Advance) or to increase the cost to such Lender, any LC Issuer or such other Recipient of participating in, issuing or maintaining any Facility LC or to reduce
the amount of any sum received or receivable by such Lender, such LC Issuer or such other Recipient hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender, such LC Issuer or such other Recipient, as the
case may be, such additional amount or amounts as will compensate such Lender, such LC Issuer or other Recipient for such additional costs incurred or reduction suffered. 
 (b) If any Lender or any LC Issuer determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such LC
Issuer’s capital or on the capital of such Lender’s or such LC Issuer’s holding company, if any, as a consequence of this Agreement or the Advances made by, or participations in Facility LCs held by, such Lender, or the Facility LCs
issued by such LC Issuer, to a level below that which such Lender or such LC Issuer or such Lender’s or such LC Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such
LC Issuer’s policies and the policies of such Lender’s or such LC Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such LC Issuer such additional amount or
amounts as will compensate such Lender or such LC Issuer or such Lender’s or such LC Issuer’s holding company for any such reduction suffered. 
 (c) A certificate of a Lender or an LC Issuer setting forth the amount or amounts necessary to compensate such Lender or such LC Issuer or its holding company, as the case may be, as specified in
paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such LC Issuer the amount shown as due on any such certificate within 10 days
after receipt thereof. 

  
 -19-

 (d) Failure or delay on the part of any Lender or any LC Issuer to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender’s or such LC Issuer’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an LC Issuer pursuant to this
Section for any increased costs or reductions incurred more than 90 days prior to the date that such Lender or such LC Issuer notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or
such LC Issuer’s intention to claim compensation therefor; provided, further, that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 90-day period referred to above shall be extended
to include the period of retroactive effect thereof, provided that such demand is made within 90 days after the implementation of such retroactive Change in Law. 
 SECTION 2.12 Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar
Advances or to fund or maintain Eurodollar Advances hereunder, (i) the obligation of such Lender to make, continue or convert Advances into Eurodollar Advances shall be suspended (subject to the following paragraph of this
Section 2.12) until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist and (ii) all Eurodollar Advances of such Lender then outstanding shall, on the
last day of the then applicable Interest Period (or such earlier date as such Lender shall designate upon not less than five Business Days’ prior written notice to the Administrative Agent), be automatically converted into Base Rate Advances.

 If the obligation of any Lender to make, continue or convert into Eurodollar Advances has been suspended pursuant to the
preceding paragraph, then, unless and until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, (i) all Advances that would otherwise be made by such Lender as
Eurodollar Advances shall instead be made as Base Rate Advances and (ii) to the extent that Eurodollar Advances of such Lender have been converted into Base Rate Advances pursuant to the preceding paragraph or made instead as Base Rate Advances
pursuant to the preceding clause (i), all payments and prepayments of principal that would have otherwise been applied to such Eurodollar Advances of such Lender shall be applied instead to such Base Rate Advances of such Lender. 

SECTION 2.13 Payments and Computations. 
 (a) The Borrower shall make each payment hereunder not later than 10:00 A.M. on the day when due in U.S. dollars to the Administrative Agent at its address referred to in Section 8.02 in same
day funds without setoff, counterclaim or other deduction. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, facility fees and letter of credit fees ratably (other
than amounts payable pursuant to Section 2.02(b), 2.11, 2.14 or 8.04(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount
payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information
contained therein in the Register pursuant to Section 8.07(d), from the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to
the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 

  
 -20-

 (b) The Borrower hereby authorizes each Lender, if and to the extent any payment owed to
such Lender by the Borrower is not made when due hereunder, to charge from time to time against any of the Borrower’s accounts with such Lender any amount so due. Each Lender agrees to notify the Borrower promptly after any such set-off and
application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. 
 (c) All computations of interest based on the Prime Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all other computations of interest and
of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are
payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. 
 (d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of any interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of a Eurodollar Advance to be made in the next following calendar month, such
payment shall be made on the next preceding Business Day. 
 (e) Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due by the Borrower to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the
Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower
shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such
amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate. 
 (f) Notwithstanding anything to the contrary contained herein, any amount payable by the Borrower hereunder that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to
the fullest extent permitted by law) bear interest from the date when due until paid in full at a rate per annum equal at all times to the Alternate Base Rate plus the Applicable Margin in effect from time to time plus 2%, payable upon demand.

 SECTION 2.14 Taxes. 
 (a) Each payment by or on account of the Borrower under this Agreement shall be made without withholding for any Taxes, unless such withholding is required by any law. If any Withholding Agent determines,
in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with
applicable law. If such Taxes are Indemnified Taxes, then the amount payable by the Borrower shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section),
the applicable Recipient receives the amount it would have received had no such withholding been made. 
 (b) The Borrower shall
timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 

  
 -21-

 (c) As soon as practicable after any payment of Indemnified Taxes by the Borrower to a
Governmental Authority, the Borrower shall deliver to the Administrative 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 Administrative Agent. 
 (d) The Borrower shall indemnify each Recipient for any
Indemnified Taxes that are paid or payable by such Recipient in connection with this Agreement (including amounts paid or payable under this Section 2.14(d)) 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. The indemnity under this Section 2.14(d) shall be paid within 10 days after the Recipient delivers to the Borrower a
certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient and describing in reasonable detail the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent
manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent. 
 (e) Each Lender shall
severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes, only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the
obligation of the Borrower to do so) attributable to such Lender that are paid or payable by the Administrative Agent in connection with this Agreement 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, as a result of the failure by such Lender to deliver, or as a result of the inaccuracy, inadequacy or deficiency of, any documentation required to be delivered by
such Lender to the Borrower or the Administrative Agent pursuant to Section 2.14(f); provided that no Lender shall be liable for the portion of any interest, expenses or penalties that are found by a final non-appealable decision
of a court of competent jurisdiction to have resulted from the Administrative Agent’s gross negligence or willful misconduct. The indemnity under this Section 2.14(e) shall be paid within 10 days after the Administrative Agent
delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent and, if requested by the applicable Lender, a copy of any notice of claim of the relevant Governmental Authority at the time
the Administrative Agent makes a written demand for indemnification. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. 
 (f) Status of Lenders. 
 (i) Any Lender that is entitled to an
exemption from, or reduction of, any applicable withholding Tax with respect to any payments under this Agreement shall promptly deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the
Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender,
if requested by the Borrower or the Administrative Agent, shall promptly deliver such other documentation prescribed by law or at the time or times reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent to determine whether or not such Lender is subject to any withholding (including 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 Section 2.14(f)(ii)(A) through (E) and Section 2.14(f)(iii) below) shall not be required if the Lender notifies the
Borrower and the Administrative 

  
 -22-

 
Agent that the Lender is waiving its rights under this Section 2.14 to indemnification of the withholding Taxes to which the requested documentation relates. Upon the reasonable
request of the Borrower or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 2.14(f). If any form or certification previously delivered pursuant to this Section
expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify the Borrower and the Administrative Agent in
writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so. 
 (ii) Without limiting the generality of the foregoing, if the Borrower is a U.S. Person, any Lender with respect to the Borrower shall, if it is legally eligible to do so, deliver to the Borrower and the
Administrative Agent (in such number of copies reasonably requested by the Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto, duly completed and executed copies of whichever of the following
is applicable: 
 (A) in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is
exempt from U.S. Federal backup withholding tax; 
 (B) 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 (1) with respect to payments of interest under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the
“interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the
“business profits” or “other income” article of such tax treaty; 
 (C) in the case of a
Non-U.S. Lender for whom payments under this Agreement constitute income that is effectively connected with such Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI; 

(D) 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 both (1) IRS Form W-8BEN and (2) a certificate substantially in the appropriate form of Exhibit E (a “U.S. Tax Certificate”) to the effect that such Lender is not (a) a “bank” within
the meaning of Section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code (c) a “controlled foreign corporation” described in
Section 881(c)(3)(C) of the Code and (d) conducting a trade or business in the United States with which the relevant interest payments are effectively connected; 

(E) in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under this Agreement (including a
partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of each such
beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Non-U.S. Lender is a partnership providing an IRS Form W-8IMY on behalf of itself and one or more of its
partners are claiming the exemption for portfolio interest under Section 881(c) of the 

  
 -23-

 
Code, such Non-U.S. Lender may provide a U.S. Tax Certificate on behalf of such partners; or 
 (F) any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation necessary to enable the Borrower
or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld. 
 (iii) If a
payment made to a Lender under this Agreement 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 the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding 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 the Withholding Agent as may be necessary for the Withholding Agent to comply with its
obligations under FATCA, to determine that such Lender has or has not 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
Section 2.14(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 
 (g) 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 2.14
(including additional amounts paid pursuant to this Section 2.14), 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 with respect to the Taxes
giving rise to such refund, including additional amounts paid pursuant to this Section 2.14), net of all out-of-pocket expenses (including any Taxes payable on account of such refund) 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 to such indemnified party pursuant to
the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the
contrary in this Section 2.14(g), in no event will any indemnified party be required to pay any amount to any indemnifying party pursuant to this Section 2.14(g) if such payment would place such indemnified party in a less
favorable position (on a net after-Tax basis) than such indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.14(g) shall not be
construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person. 

(h) Without prejudice to the survival of any other agreement of the Borrower or any Lender hereunder, the agreements and obligations of
the Borrower and the Lenders contained in this Section 2.14 shall survive the payment in full of principal and interest hereunder and the termination of this Agreement; provided that no Lender shall be entitled to demand any
payment from the Borrower under this Section 2.14 more than one year following the payment to or for the account of such Lender of all other amounts payable by the Borrower hereunder to such Lender and the termination of such
Lender’s Commitment; provided, further, that the foregoing proviso shall in no way limit the right of any Lender to demand or receive any payment under this Section 2.14 to the extent that such payment relates to the
retroactive application of any Taxes or Other Taxes if such demand is made within one year after the implementation of such Taxes or Other Taxes. 

  
 -24-

 (i) For purposes of Section 2.14(e) and (f), the term “Lender”
includes any LC Issuer. 
 SECTION 2.15 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by it to the Borrower or its participation interest in any Facility LC issued for the account of the Borrower (other than pursuant to
Section 2.02(b), 2.11, 2.14, 2.17.7 or 8.04(b)) in excess of its ratable share of payments on account of the Advances to the Borrower and LC Obligations obtained by all Lenders, such Lender shall forthwith
purchase from the other Lenders such participations in the Advances and/or LC Obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided that if all or any portion of such
excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount
equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. 

SECTION 2.16 Facility LCs. 
 SECTION 2.16.1 Issuance. Each LC Issuer agrees, on the terms and conditions set forth in this Agreement (including the limitations set forth in Sections 2.01, 2.19 and
3.02), upon the request of the Borrower, to issue standby and direct pay letters of credit and to extend, increase or otherwise modify Facility LCs (“Modify”, and each such action a “Modification”) for the
Borrower, from time to time from the date of this Agreement to the Termination Date; provided that (a) the aggregate amount of LC Obligations owed by the Borrower to any LC Issuer shall not exceed the amount of such LC Issuer’s LC
Pro Rata Share of the LC Sublimit (or such higher amount agreed upon in writing between the Borrower and such LC Issuer); (b) the aggregate amount of all LC Obligations shall not exceed the LC Sublimit; (c) the stated amount of all
Facility LCs that have scheduled expiry dates after the next scheduled Termination Date for any Lender plus the aggregate principal amount of all Eurodollar Advances that have Interest Periods ending after such Termination Date shall not exceed the
remainder of (i) the Aggregate Commitment Amount minus (ii) the aggregate amount of the Commitments that are scheduled to terminate on such Termination Date; and (d) no LC Issuer shall be obligated to issue or Modify any Facility LC
if (i) any order, judgment or decree of any court or other governmental authority shall by its terms purport to enjoin or restrain such LC Issuer from issuing such Facility LC or (ii) any applicable law, or any request or directive from
any governmental authority having jurisdiction over such LC Issuer, shall prohibit, or request or direct that such LC Issuer refrain from, the issuance of letters of credit generally or of such Facility LC in particular. Facility LCs may be issued
for any proper corporate purpose. Each Facility LC 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 Facility LC (or, in the case of any renewal or extension
thereof, one year after such renewal or extension and provided that such Facility LC may contain customary “evergreen” provisions pursuant to which the expiry date is automatically extended by a specific time period unless such LC Issuer
gives notice to the beneficiary of such Facility LC at least a specified time period prior to the expiry date then in effect) and (ii) the date that is five Business Days prior to the next scheduled Termination Date in effect at the time of
issuance, renewal or extension; provided that with the prior consent of the Administrative Agent and the applicable LC Issuer, such LC Issuer may issue or extend a Facility LC with a later expiration date so long as on or before the date

  
 -25-

 
which is seven Business Days prior to the last scheduled Termination Date, whether or not an Event of Default exists, the Borrower shall deposit cash collateral with the Administrative Agent in
accordance with Section 2.16.12 in respect of all outstanding Facility LCs with an expiration date later than five Business Days prior to the last scheduled Termination Date. Any Facility LC theretofore issued which contains an
“evergreen” or similar automatic extension feature shall, unless the Borrower shall have notified the Administrative Agent and the applicable LC Issuer in writing not less than thirty (30) days (or such shorter period as may be
acceptable to the applicable LC Issuer in its sole discretion or such longer period as may be required by the beneficiary of such Facility LC) prior to the date that such Facility LC is scheduled to be automatically extended that the Borrower
desires that such Facility LC not be so extended, be automatically extended in accordance with the terms thereof subject to the applicable LC Issuer’s right not to so extend if the conditions precedent to the issuance of such Facility LC would
not be satisfied. If the Borrower is required to provide an amount of cash collateral hereunder as a result of an approaching Termination Date, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three
(3) Business Days after all Facility LCs have expired and all related LC Obligations are satisfied in full. By their execution of this Agreement, the parties hereto agree that on the Effective Date (without any further action by any Person),
each Existing Letter of Credit shall be deemed to have been issued under this Agreement and the rights and obligations of the issuer and the account party thereunder shall be subject to the terms hereof. 

SECTION 2.16.2 Participations. Upon the issuance or Modification by an LC Issuer of a Facility LC in
accordance with this Section 2.16 (or, in the case of the Existing Letters of Credit, on the Effective Date), the applicable LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably
sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the
related LC Obligations in proportion to its Pro Rata Share. 
 SECTION 2.16.3 Notice. Subject to
Section 2.16.1, the Borrower shall give the applicable LC Issuer notice prior to 11:00 A.M. at least five Business Days (or such lesser time as the applicable LC Issuer may agree) prior to the proposed date of issuance or Modification of
each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported
thereby. Upon receipt of such notice, the applicable LC Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s
participation in such proposed Facility LC. The issuance or Modification by an LC Issuer of any Facility LC shall, in addition to the applicable conditions precedent set forth in Article III (the satisfaction of which an LC Issuer shall have
no duty to ascertain; provided that no LC Issuer shall issue a Facility LC if such LC Issuer shall have received written notice (which has not been rescinded) from the Administrative Agent or any Lender that any applicable condition precedent
to the issuance or modification of such Facility LC has not been satisfied and, in fact, such condition precedent is not satisfied at the requested time of issuance), be subject to the conditions precedent that such Facility LC shall be satisfactory
to the applicable LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as such LC Issuer shall have reasonably requested (each a
“Facility LC Application”). In the event of any conflict (including any additional terms requiring the posting of collateral) between the terms of this Agreement and the terms of any Facility LC Application, the terms of this
Agreement shall control.

 SECTION 2.16.4 LC Fees. The Borrower agrees to pay to the
Administrative Agent, for the account of each Lender, a letter of credit fee at a rate per annum equal to the LC Fee Rate on such Lender’s Pro Rata Share of the undrawn stated amount of all Facility LCs for the period from the Effective Date to
such Lender’s Termination Date (or, if later, the date on which such Lender has no participation interests in the Facility LCs), payable in arrears on the last day of each March, June, September and December and on the applicable Termination
Date (and, if applicable, thereafter on demand). The Borrower also agrees to pay to the applicable LC Issuer for its own account (a) fronting fees in amounts and at times agreed upon between such LC Issuer and the Borrower and
(b) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with such LC Issuer’s standard schedule for such charges as in effect from time to time. 

SECTION 2.16.5 Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC
of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each Lender as to the amount to be paid by such LC Issuer as a
result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of an LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment)
delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. Each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of the
Termination Date (but subject to Sections 2.17 and 2.16.12), the occurrence of any Event of Default or Unmatured Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand for (i) such
Lender’s Pro Rata Share of the amount of each payment made by such LC Issuer under any Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.16.6, plus (ii) interest on the foregoing
amount to be reimbursed by such Lender, for each day from the date of such LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 A.M. on such day, from the next succeeding Business Day) to the date on which such
Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Rate for the first three days and, thereafter, at the Alternate Base Rate. 

SECTION 2.16.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to
reimburse the applicable LC Issuer on or before the applicable LC Payment Date for any amount to be paid by such LC Issuer upon any drawing under any Facility LC issued for the account of the Borrower, without presentment, demand, protest or other
formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the
extent, caused by (i) the willful misconduct or gross negligence (as finally determined by a court of competent jurisdiction) of the applicable LC Issuer in determining whether a request presented under any Facility LC complied with the terms
of such Facility LC or (ii) the applicable LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. If the Borrower fails to fully
reimburse the applicable LC Issuer by 11:00 A.M. on an LC Payment Date, such LC Issuer shall promptly notify the Administrative Agent. Upon receipt of such notice, the Administrative Agent shall promptly notify each Lender of such LC Payment Date,
the amount of the unpaid Reimbursement Obligations and such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested Base Rate Advances to be disbursed on the applicable LC Payment Date in an amount equal
to the unpaid Reimbursements Obligations, without regard to the minimum and multiples specified for Base Rate Advances in Section 2.02(e), but subject to the conditions set forth in Article III. All

  
 -27-

 
Reimbursement Obligations that are not fully refinanced by the making of Base Rate Advances because the Borrower cannot satisfy the conditions set forth in Article III or for any other
reason shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin plus 2%. The applicable LC Issuer will pay to each Lender ratably in accordance with its Pro Rata
Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligations in respect of any Facility LC issued by such LC Issuer, but only to the extent such Lender has made payment to such
LC Issuer in respect of such Facility LC pursuant to Section 2.16.5. 
 SECTION 2.16.7
Obligations Absolute. The Borrower’s obligations under this Section 2.16 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have against any LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower agrees with the LC Issuers and the Lenders that the LC Issuers and the Lenders shall not be responsible for, and the Reimbursement Obligations in
respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of
any of its Affiliates against the beneficiary of any Facility LC or any such transferee. No LC Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted,
in connection with any Facility LC. The Borrower agrees that any action taken or omitted by any LC Issuer or any Lender under or in connection with any Facility LC and the related drafts and documents, if done without gross negligence or willful
misconduct (as finally determined by a court of competent jurisdiction), shall be binding upon the Borrower and shall not put the applicable LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.16.7 is
intended to limit the right of the Borrower to make a claim against an LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.16.6. 

SECTION 2.16.8 Actions of LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected
in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, facsimile, message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by
the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such LC Issuer. An LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement
unless it shall first have received such advice or concurrence of the Majority Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.16, an LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under
this Agreement in accordance with a request of the Majority Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holder of a participation in any Facility LC. 

SECTION 2.16.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, each LC
Issuer and the Administrative Agent, and their respective directors, officers, agents and employees, from and against any claim, damage, loss, liability, cost or expense which such Lender, such LC Issuer or the Administrative Agent may incur (or
which may be claimed against such Lender, such LC Issuer or the Administrative Agent by any Person 

  
 -28-

 
whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility
LC, including any claim, damage, loss liability, cost or expense which the applicable LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to such LC Issuer
hereunder (but nothing herein contained shall affect any right the Borrower may have against any Defaulting Lender) or (ii) by reason of or on account of such LC Issuer issuing any Facility LC that specifies that the term
“Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document,
satisfactory to such LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, any LC Issuer or the Administrative Agent for any claim, damage, loss,
liability, cost or expense to the extent, but only to the extent, caused by (a) the willful misconduct or gross negligence (as finally determined by a court of competent jurisdiction) of an LC Issuer in determining whether a request presented
under any Facility LC complied with the terms of such Facility LC or (b) an LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC.
Nothing in this Section 2.16.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement. 
 SECTION 2.16.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the applicable LC Issuer, its Affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such
indemnitees’ gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) or such LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the
terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder. 

SECTION 2.16.11 Rights as a Lender. In its capacity as a Lender, each LC Issuer shall have the same rights and
obligations as any other Lender. 
 SECTION 2.16.12 Cash Collateralization. In the event the Borrower
is required to deposit cash collateral pursuant to the provisions of this Article II, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in
cash equal to 105% of the LC Obligations as of such date plus any accrued and unpaid interest thereon. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the LC Obligations. The Administrative
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 at the option and sole discretion of
the Administrative Agent and at the 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
Administrative Agent to reimburse the applicable LC Issuer for amounts paid by such LC Issuer in respect of a Facility LC for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement
obligations of the Borrower for the LC Obligations. For the avoidance of doubt, no Lender shall have any reimbursement obligations under Section 2.16.5 in respect of any LC Obligations with respect to any Facility LC for which cash
collateral has been deposited in accordance with the terms of this Agreement. 
 SECTION 2.17 Extensions of Scheduled
Termination Date. 

  
 -29-

 SECTION 2.17.1 Extension Requests. The Borrower may, not more
than two (2) times, by notice to the Administrative Agent (which shall promptly notify each Lender) not earlier than 60 and not later than 30 days prior to any anniversary of the Effective Date (each, an “Anniversary Date”),
request that each Lender extend such Lender’s scheduled Termination Date then in effect (the “Existing Termination Date”) for an additional year from the Existing Termination Date, it being understood that the Termination Date
shall not be later than the seventh anniversary of the Effective Date as a result of any such request. 

SECTION 2.17.2 Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall,
by notice to the Administrative Agent given not later than the date (the “Notice Date”) that is 20 days prior to the applicable Anniversary Date, notify the Administrative Agent whether such Lender agrees to the requested extension
of the Termination Date (each Lender that determines not to so extend its Termination Date, a “Declining Lender”). Any Lender that does not advise the Administrative Agent on or before the Notice Date that it has agreed to extend
the Existing Termination Date shall be deemed to be a Declining Lender. 
 SECTION 2.17.3 Notification by
Administrative Agent. The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section no later than the date 15 days prior to the applicable Anniversary Date. 

SECTION 2.17.4 Additional Commitment Lenders. The Borrower shall have the right, at any time after a Lender
has become a Declining Lender, to require such Declining Lender to assign and delegate its rights and obligations hereunder to one or more existing Lenders or other financial institutions that have agreed to assume such rights and obligations (each
an “Additional Commitment Lender”) pursuant to, and in accordance with the requirements of, Section 8.07. 
 SECTION 2.17.5 Minimum Extension Requirement. If (and only if) the total of the Commitments of the Lenders (including Additional Commitment Lenders) that have agreed so to extend their
Termination Date (each an “Extending Lender”) shall be more than 50% of the Aggregate Commitment Amount in effect immediately prior to the Anniversary Date, then, effective as of such date, the Termination Date of each Extending
Lender (including any applicable Additional Commitment Lender) shall be extended to the date falling one year after the Existing Termination Date (except that, if such date is not a Business Day, such Termination Date as so extended shall be the
next preceding Business Day). 
 SECTION 2.17.6 Conditions to Effectiveness of Extensions.
Notwithstanding the foregoing, no extension of the Termination Date pursuant to this Section shall be effective unless: 
 (a) no
Event of Default or Unmatured Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto; 
 (b) the representations and warranties of the Borrower contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of
such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and 
 (c) subject to Section 8.07(h), each LC Issuer shall have consented to such extension (which consent shall not be unreasonably delayed or withheld). 

SECTION 2.17.7 Effect of Termination Date for some but not all Lenders. If the scheduled Termination Date for
one or more Lenders (each an “Exiting Lender”) occurs on a date 

  
 -30-

 
that is not the Termination Date for all Lenders, then on such Termination Date (a) the Borrower shall repay all amounts payable to the Exiting Lenders in accordance with
Section 2.05, (b) the Commitments of the Exiting Lenders, and the participations of the Exiting Lenders in Facility LCs, shall terminate and (c) the Pro Rata Shares and the participations in Facility LCs of the remaining
Lenders shall be redetermined pro rata in accordance with their respective Commitment Amounts after giving effect to the terminations described in clause (b) above; provided that if an Event of Default or Unmatured Event of
Default exists on such Termination Date and either (i) the Borrower fails to pay in full all amounts payable to the Exiting Lenders or (ii) the Majority Lenders so request, then the participations of the Exiting Lenders in Facility
LCs shall not terminate and no redetermination of the participations of the Lenders in Facility LCs shall be made until the earlier of the first Business Day after such Termination Date on which no Event of Default or Unmatured Event of Default
exists and the date specified by the Majority Lenders in a notice to the Administrative Agent (which shall promptly advise each Lender). Nothing in the proviso clause to the preceding sentence shall affect the termination of the Commitment of an
Exiting Lender on the relevant Termination Date (except with respect to such Exiting Lender’s participation in Facility LCs) or any Exiting Lender’s right to demand immediate repayment of all amounts owed to such Exiting Lender by the
Borrower hereunder and to pursue remedies with respect thereto. Further, if at any time after the relevant Termination Date (x) the Borrower has not paid all principal, interest and facility fees payable to one or more Exiting Lenders hereunder
and (y) the Lenders (excluding any Exiting Lender) elect to make Advances, then all proceeds of such Advances shall be applied to pay the amounts owed by the Borrower to such Exiting Lenders (ratably based upon the amounts owed to such Lenders)
until such principal, interest and facility fees have been paid in full. 
 SECTION 2.18 Optional Increase in
Commitments. The Borrower may, from time to time, by means of a letter delivered to the Administrative Agent substantially in the form of Exhibit C, request that the Aggregate Commitment Amount be increased by an aggregate amount (for all
such increases) not exceeding $250,000,000 by (a) increasing the Commitment Amount of one or more Lenders that have agreed to such increase (in their sole discretion) and/or (b) adding one or more commercial banks or other Persons as a
party hereto (each an “Additional Lender”) with a Commitment Amount in an amount agreed to by any such Additional Lender; provided that (i) any increase in the Aggregate Commitment Amount shall be in an aggregate amount
of $25,000,000 or a higher integral multiple of $1,000,000; (ii) no Additional Lender shall be added as a party hereto without the written consent of the Administrative Agent and the LC Issuers (which consents shall not be unreasonably
withheld) or if an Event of Default or an Unmatured Event of Default exists; (iii) subject to Section 8.07(h), no such increase shall be effective without the written consent of the LC Issuers (which consent shall not be
unreasonably withheld or delayed); and (iv) the Borrower may not request an increase in the Aggregate Commitment Amount unless the Borrower has delivered to the Administrative Agent (with a copy for each Lender) a certificate (A) stating
that any applicable governmental authority has approved such increase, (B) attaching evidence, reasonably satisfactory to the Administrative Agent, of each such approval and (C) stating that the representations and warranties contained in
Section 4.01 are correct on and as of the date of such certificate as though made on and as of such date and that no Event of Default or Unmatured Event of Default exists on such date. Any increase in the Aggregate Commitment Amount
pursuant to this Section 2.18 shall be effective three Business Days after the date on which the Administrative Agent has received and accepted the applicable increase letter in the form of Annex 1 to Exhibit C (in the case
of an increase in the Commitment Amount of an existing Lender) or assumption letter in the form of Annex 2 to Exhibit C (in the case of the addition of a commercial bank or other Person as a new Lender). The Administrative Agent shall
promptly notify the Borrower and the Lenders of any increase in the Aggregate Commitment Amount pursuant to this Section 2.18 and of the Commitment Amount and Pro Rata Share of each Lender after giving effect thereto. The Borrower shall
prepay any Advances outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 8.04(b)) to the extent 

  
 -31-

 
necessary to keep the outstanding Advances ratable among the Lenders in accordance with any revised Pro Rata Shares arising from any non-ratable increase in the Commitment Amounts under this
Section 2.18; provided that, notwithstanding any other provision of this Agreement, the Administrative Agent, the Borrower and each increasing Lender and Additional Lender, as applicable, may make arrangements satisfactory to such
parties to cause an increasing Lender or an Additional Lender to temporarily hold risk participations in the outstanding Advances of the other Lenders (rather than fund its Pro Rata Share of all outstanding Advances concurrently with the applicable
increase) with a view toward minimizing breakage costs and transfers of funds in connection with any increase in the Aggregate Commitment Amount. To the extent that any increase pursuant to this Section 2.18 is not expressly authorized
pursuant to resolutions or consents delivered pursuant to Section 3.01(b)(i), the Borrower shall, prior to the effectiveness of such increase, deliver to the Administrative Agent a certificate signed by an authorized officer of the
Borrower certifying and attaching the resolutions or consents that have been adopted to approve or consent to such increase. 

SECTION 2.19 Defaulting Lenders. 
 Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

 (a) fees shall cease to accrue on the unutilized portion of the Commitment of such Defaulting Lender pursuant to
Section 2.03; 
 (b) the Commitment Amount and LC Obligations of such Defaulting Lender shall not be included in
determining whether all Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 8.01); provided that, any waiver, amendment or modification
(i) requiring the consent of all Lenders or each affected Lender, which affects such Defaulting Lender differently than other affected Lenders or (ii) under Section 8.01(b), (c), (d) or
(f) (except, in the case of Section 8.01(c) or (d), with respect to fees as contemplated under this Section 2.19), shall in each case require the consent of such Defaulting Lender; 

(c) if any LC Obligations exist at the time a Lender becomes a Defaulting Lender then: 

(i) all or any part of such LC Obligations shall be reallocated among the non-Defaulting Lenders in accordance with their
respective Pro Rata Shares but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s LC Obligations does not exceed the total of all non-Defaulting Lenders’
Commitment Amounts, (y) the sum of each non-Defaulting Lender’s Revolving Credit Exposure plus the portion of such Defaulting Lender’s LC Obligations allocated to such non-Defaulting Lender does not exceed such non-Defaulting
Lender’s Commitment Amount and (z) the conditions set forth in Section 3.02 are satisfied at such time; 
 (ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Administrative Agent (after
giving effect to any partial reallocation pursuant to clause (i) above) cash collateralize such Defaulting Lender’s LC Obligations in accordance with the procedures set forth in Section 2.16.12 for so long as such LC Obligation
is outstanding; 
 (iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC
Obligations pursuant to this Section 2.19(c), the Borrower shall not be 

  
 -32-

 
required to pay any fees to such Defaulting Lender pursuant to Section 2.16.4 with respect to such Defaulting Lender’s LC Obligations during the period such Defaulting
Lender’s LC Obligations are cash collateralized; 
 (iv) if the LC Obligations of the non-Defaulting Lenders
are reallocated pursuant to this Section 2.19(c), then the fees payable to the Lenders pursuant to Section 2.16.4 shall be adjusted in accordance with such non-Defaulting Lenders’ Pro Rata Shares; and 

(v) if any Defaulting Lender’s LC Obligations are neither cash collateralized nor reallocated pursuant to this
Section 2.19(c), then, without prejudice to any rights or remedies of the LC Issuers or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such
Defaulting Lender’s Commitment that was utilized by such LC Obligations) and letter of credit fees payable under Section 2.16.4 with respect to such Defaulting Lender’s LC Obligations shall be payable to the applicable LC
Issuers until such LC Obligations are cash collateralized and/or reallocated; and 
 (d) so long as any Lender is a Defaulting
Lender, no LC Issuer shall be required to issue, amend or increase any Facility LCs, unless it is satisfied that the related exposure and the Defaulting Lender’s then outstanding LC Obligations will be 100% covered by the Commitments of the
non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.19(c), and participating interests in any such newly issued or increased Facility LC shall be allocated among non-Defaulting
Lenders in a manner consistent with Section 2.19(c)(i) (and Defaulting Lenders shall not participate therein). 
 In
the event that the Administrative Agent, the Borrower, each LC Issuer each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Obligations 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 Advances of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender
to hold such Advances in accordance with its Pro Rata Share.

hereunder in its capacity as a Lender, JPMCB shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent; and the term “Lender” or
“Lenders” shall include JPMCB in its individual capacity. JPMCB and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower, any Affiliate
thereof and any Person who may do business with or own securities of the Borrower or any such Affiliate, all as if it were not Administrative Agent and without any duty to account therefor to the Lenders. 

SECTION 7.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on the financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed 

  
 -45-

 
appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent
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. 

SECTION 7.05 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the
Borrower), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Administrative Agent under this Agreement, provided that no Lender
shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. Without
limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any out-of-pocket expenses (including reasonable counsel fees) incurred by the Administrative Agent in connection with
the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the
extent that such expenses are reimbursable by the Borrower but for which the Administrative Agent is not reimbursed by the Borrower. 
 SECTION 7.06 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time
with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the
Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank described in clause (i) or (ii) of the definition of “Eligible Assignee” having a
combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s
resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.
Notwithstanding the foregoing, if no Event of Default or Unmatured Event of Default shall have occurred and be continuing, then no successor Administrative Agent shall be appointed under this Section 7.06 without the prior written
consent of the Borrower, which consent shall not be unreasonably withheld or delayed. 
 SECTION 7.07 Co-Documentation
Agents, Co-Syndication Agents, Joint Active Lead Arrangers, Joint Passive Arrangers, Joint Active Bookrunners and Joint Passive Bookrunners. The titles “Co-Documentation Agents,” “Co-Syndication Agents”, “Joint Active
Lead Arrangers”, “Joint Passive Arrangers”, “Joint Active Bookrunners”, and “Joint Passive Bookrunners” (each, in such capacity or capacities, a “Titled Person”) are purely honorific, and no Person
designated as a Titled Person shall have any duties or responsibilities in such capacity and no Titled Person shall have or be deemed to have any fiduciary relationship with any Lender or with the Borrower or any of its Affiliates.

any Lender, any LC Issuer or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. 
 SECTION 8.04 Costs and Expenses; Indemnification. 

  
 -47-

 (a) The Borrower agrees to pay on demand all costs and expenses incurred by the
Administrative Agent and the Joint Active Lead Arrangers in connection with the preparation, execution, delivery, administration, syndication, modification and amendment of this Agreement and the other documents to be delivered hereunder, including
the reasonable fees, internal charges and out-of-pocket expenses of counsel (including in-house counsel) for the Administrative Agent and the Joint Active Lead Arrangers with respect thereto and with respect to advising the Administrative Agent and
the Joint Active Lead Arrangers as to their respective rights and responsibilities under this Agreement. The Borrower further agrees to pay on demand all costs and expenses, if any (including counsel fees and expenses of outside counsel and of
internal counsel), incurred by the Administrative Agent, any LC Issuer or any Lender in connection with the collection and enforcement (whether through negotiations, legal proceedings or otherwise) of the Borrower’s obligations under this
Agreement and the other documents to be delivered by the Borrower hereunder, including reasonable counsel fees and expenses in connection with the enforcement of rights under this Section 8.04(a). 

(b) If any payment of principal of, or any conversion of, any Eurodollar Advance is made other than on the last day of the Interest
Period for such Advance, as a result of a payment or conversion pursuant to Section 2.09 or 2.12 or acceleration of the maturity of the Advances pursuant to Section 6.01 or for any other reason, the Borrower shall,
upon demand by any Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amount required to compensate such Lender for any additional loss, cost or expense which it may
reasonably incur as a result of such payment or conversion, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance. 

(c) The Borrower agrees to indemnify and hold each Lender, each LC Issuer, each Agent and each of their respective Affiliates, officers,
directors, advisors, agents and employees (each, an “Indemnified Person”) harmless from and against any claim, damage, loss, liability, cost or expense (including reasonable attorney’s fees and expenses, whether or not such
Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) that any of them may pay or incur arising out of or relating to this Agreement or the transactions
contemplated hereby, or the use by the Borrower or any Subsidiary of the proceeds of any Advance; provided that the Borrower shall not be liable for any portion of any such claim, damage, loss, liability, cost or expense resulting from such
Indemnified Person’s gross negligence or willful misconduct as determined in a final non-appealable order of a court of competent jurisdiction. The Borrower’s obligations under this Section 8.04(c) shall survive the repayment
of all amounts owing by the Borrower to the Lenders and the Administrative Agent under this Agreement and the termination of the Commitments and this Agreement. If and to the extent that the obligations of the Borrower under this
Section 8.04(c) are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law. This Section 8.04(c) shall not apply
with respect to Taxes other than any Taxes that represent losses or damages arising from any non-Tax claim. In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective
whether or not such investigation, litigation or proceeding is brought by the Borrower, any of the Borrower’s equityholders or creditors, an Indemnified Person or any other person or entity, whether or not an Indemnified Person is otherwise a
party thereto. 
 SECTION 8.05 Right of Set-off. Upon (i) the occurrence and during the continuance of any
Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances due and payable pursuant to the provisions of
Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time 

  
 -48-

 
owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement,
whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. Each Lender agrees to notify the Borrower promptly after any such set-off and application made by such Lender or Affiliate
thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.05 are in addition to other rights and remedies (including other
rights of set-off) that such Lender may have. 
 SECTION 8.06 Binding Effect. This Agreement shall be binding upon
and inure to the benefit of the Borrower, the Agents and each Lender and their respective successors and assigns, provided that (except as permitted by Section 5.02(b)(iii)) the Borrower shall not have the right to assign rights
hereunder or any interest herein without the prior written consent of all Lenders. 
 SECTION 8.07 Assignments and
Participations. 
 (a) Each Lender may, with the prior written consent of the Borrower, each LC Issuer and the
Administrative Agent (which consents shall not be unreasonably withheld or delayed), and if demanded by the Borrower pursuant to Section 8.07(g) shall to the extent required by such Section, assign to one or more banks or other entities
all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it and its participation in Facility LCs); provided that (i) each such assignment shall be of a
constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the Commitment Amount of the assigning Lender being assigned pursuant to each such assignment (determined as of the
date of the Assignment and Assumption with respect to such assignment) shall in no event be less than $5,000,000 or, if less, the entire amount of such Lender’s Commitment, and shall be an integral multiple of $1,000,000 or such Lender’s
entire Commitment, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment
and Assumption, together with a processing and recordation fee of $3,500 (which shall be payable by one or more of the parties to the Assignment and Assumption, and not by the Borrower (except in the case of a demand under
Section 8.07(g)), and shall not be payable if the assignee is a Federal Reserve Bank), (v) the consent of the Borrower shall not be required after the occurrence and during the continuance of any Event of Default, and (vi) the
Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof. Upon such execution, delivery,
acceptance and recording, from and after the effective date specified in each Assignment and Assumption, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it
pursuant to such Assignment and Assumption, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Assumption, relinquish its rights and be released from its obligations under this Agreement and, in the case of an Assignment and Assumption covering all or the remaining portion of an assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto (although an assigning Lender shall continue to be entitled to indemnification pursuant to Section 8.04(c)). Notwithstanding anything contained in this
Section 8.07(a) to the contrary, (A) the consent of the Borrower and the Administrative Agent shall not be required with respect to any assignment by any Lender to an Affiliate of such Lender or to another Lender or to an Approved
Fund, and (B) any Lender may at any time, without the consent of the Borrower, any LC Issuer or the Administrative Agent, and without any requirement to have an Assignment and Assumption executed, assign all or any part of its rights under this
Agreement to a Federal Reserve Bank, provided that no such assignment shall release the transferor Lender from any of its obligations hereunder. 

  
 -49-

 For the purposes of this Section 8.07(a), the term “Approved Fund” has
the following meaning: 
 “Approved Fund” means any Person (other than a natural person) that is engaged in
making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
Affiliate of an entity that administers or manages a Lender. 
 (b) By executing and delivering an Assignment and Assumption,
the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Assumption, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the
financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (iv) such assignee
will, independently and without reliance upon the Administrative Agent, such assigning Lender 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; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their
terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender. 
 (c) The
Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Assumption delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the
Commitment Amount of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender
at any reasonable time and from time to time upon reasonable prior notice. 
 (d) Upon its receipt of an Assignment and
Assumption executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, the Administrative Agent shall, if such Assignment and Assumption has been completed and is in substantially the form of Exhibit A
(including any necessary consents of the Administrative Agent, the LC Issuers and the Borrower), (i) accept such Assignment and Assumption, (ii) record the information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower. 
 (e) Any Lender may, without the consent of the Borrower, any LC Issuer or the Administrative Agent,
sell participations to one or more banks or other entities (a “Participant”) 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 Advances 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 Borrower, the Administrative Agent and the 

  
 -50-

 
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 any amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.01 that affects such Participant. Borrower
agrees that each Participant shall be entitled to the benefits of Sections 2.11, 2.14 and 8.04(b) (subject to the requirements and limitations therein, including the requirements under Section 2.14(f) (it being understood that the
documentation required under Section 2.14(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section;
provided that such Participant (A) agrees to be subject to the provisions of Sections 2.15 and 8.07(g) as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any
greater payment under Sections 2.11 or 2.14, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change
in Law that occurs after the Participant acquired the applicable participation. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.15 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, 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 Advances or other obligations under this Agreement (the “Participant Register”); provided that no Lender shall
have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Advances or its other
obligations hereunder) except to the extent that such disclosure is necessary to establish that such Commitment, Advance, 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 this Agreement
notwithstanding any notice to the contrary. 
 (f) Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the
Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any confidential information relating to the Borrower received by it from
such Lender (subject to customary exceptions regarding regulatory requirements, compliance with legal process and other requirements of law). 
 (g) If any Lender (i) shall make demand for payment under Section 2.11(a), 2.11(b) or 2.14, (ii) shall deliver any notice to the Administrative Agent pursuant to
Section 2.12 resulting in the suspension of certain obligations of the Lenders with respect to Eurodollar Advances, (iii) does not consent to an amendment or waiver that requires the consent of all Lenders and has been approved by
the Majority Lenders, or (iv) is a Defaulting Lender, then (A) in the case of clause (i), within 60 days after such demand (if, but only if, the payment demanded under Section 2.11(a), 2.11(b) or
2.14 has been made by the Borrower), (B) in the case of clause (ii), within 60 days after such notice (if such suspension is still in effect), (C) in the case of clause (iii), within 60 days after the date the
Majority Lenders approve the applicable amendment or waiver, or (D) in the case of clause (v), at any time so long as such Lender continues to be a Defaulting Lender, as the case may be, the Borrower may demand that such Lender assign in
accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrower and reasonably acceptable to the Administrative Agent and the LC Issuers all (but not less than all) of such Lender’s rights and
obligations hereunder within the next succeeding 30 days; provided that such 

  
 -51-

 
Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in LC Obligations, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts). If any such Eligible Assignee designated by the Borrower shall fail to
consummate such assignment on terms acceptable to such Lender, or if the Borrower shall fail to designate any such Eligible Assignee for all of such Lender’s Commitment, Advances and participation in Facility LCs, then such Lender may (but
shall not be required to) assign such Commitment and Advances to any other Eligible Assignee in accordance with this Section 8.07 during such period. No replacement of a Defaulting Lender pursuant to this Section 8.07(g)
shall be deemed to be a waiver of any right that the Borrower, the Administrative Agent, any LC Issuer or any other Lender may have against such Defaulting Lender. In the event that a Lender assigns any Eurodollar Advances pursuant to this
Section 8.07(g), such assignment shall be deemed to be a prepayment by the Borrower of such Eurodollar Advances for purposes of Section 8.04(b). 
 (h) If any LC Issuer does not consent to (A) a request by the Borrower to extend the Existing Termination Date pursuant to Section 2.17 or (B) a request by the Borrower to increase
the Aggregate Commitment Amount pursuant to Section 2.18, the Borrower may upon written notice to the Administrative Agent and such LC Issuer, (i) reduce the LC Sublimit by an amount equal to such LC Issuer’s LC Pro Rata Share
of the LC Sublimit and such LC Issuer shall cease to be an LC Issuer as of the date of such notice by the Borrower pursuant to this Section 8.07(h) (in which case the consent of such LC Issuer shall not be required under
Section 2.17 or 2.18) or (ii) require such LC Issuer to assign and delegate its rights and obligations hereunder, as an LC Issuer and as a Lender in accordance with Section 8.07(g), and, in each case, the Borrower
shall make arrangements satisfactory to such LC Issuer with respect to any Facility LCs previously issued by such LC Issuer. 

(i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Bank”) may grant to a special
purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such
Granting Bank would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Advance, the Granting Bank shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Bank to the
same extent, and as if, such Advance were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the
Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding
commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of
the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 8.07, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the
Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advance to the Granting Bank or to any financial institution (consented to by the Borrower and Administrative Agent, which consents
shall be unreasonably withheld or delayed) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a confidential basis any non-public information
relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 8.07(i) may not be amended in any manner which adversely affects a
Granting Bank or an SPC without the written consent of such Granting Bank or SPC.

such amendment (which shall require the approval of the Majority Lenders), the Debt Rating shall be determined by reference to the rating most recently in effect prior to such change. If the Borrower has no Fitch Rating, no Moody’s Rating and
no S&P Rating, Pricing Level VI shall apply.
