 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

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.

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

 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.

 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

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,

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,

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,

 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

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
