 W I T N E S S E T H : 
 WHEREAS, the parties hereto have heretofore
entered into a Three-Year Credit Agreement dated as of June 30, 2004, which was amended and restated as of June 30, 2005 (the “Agreement”); and 
 WHEREAS, the parties hereto desire to amend the Agreement as set forth herein and to restate the Agreement in its entirety to read as set forth in the Agreement with the amendments specified below; 
 NOW, THEREFORE, the parties hereto agree as follows: 
 SECTION 1. Definitions; References. Unless otherwise specifically defined herein, each capitalized term used herein which is defined in the Agreement shall have the meaning assigned to such term in the Agreement. Each reference
to “hereof”, “hereunder”, “herein” and “hereby” and each other similar reference and each reference to “this Agreement” and each other similar reference contained in the Agreement shall from and
after the date hereof refer to the Agreement as amended and restated hereby. 
 SECTION 2. Extension of the Facility. The date “June
30, 2009” in the definition of “Commitment Termination Date” is changed to “June 29, 2010”. 
  
 SECTION 3. Amendments. 
 (a)
Section 1.01 of the Agreement is amended by amending the following definitions to read in their entirety as follows: 
 “Additional Bank” means any financial institution that becomes a Bank for purposes hereof pursuant to Section 2.17 or 8.06. 
 “Issuing Bank” means (i) each of JPMorgan Chase Bank, N.A. and Wachovia Bank, National Association, and (ii) any other Bank that may agree to issue letters of credit hereunder, in each case as issuer
of a Letter of Credit hereunder. No Issuing Bank shall be obligated to issue any Letter of Credit hereunder if, after giving effect thereto, the aggregate Letter of Credit Liabilities in respect of all Letters of Credit issued by such Issuing Bank
hereunder would exceed (i) in the case of any Issuing Bank named in clause (i) of the preceding sentence, $300,000,000 (as such amount may be modified from time to time by agreement between the Borrower and such Issuing Bank) or
(ii) with respect to any other Issuing Bank, such amount (if any) as may be agreed for this purpose from time to time by such Issuing Bank and the Borrower. For avoidance of doubt, the limitations in the preceding sentence are for the exclusive
benefit of the respective Issuing Banks, are incremental to the other limitations specified herein on the availability of Letters of Credit and do not affect such other limitations. 
 “Letter of Credit” means a letter of credit issued or to be issued hereunder by an Issuing Bank in accordance with
Section 2.15 and each Existing Letter of Credit. 
 “Principal Subsidiary” means each of Texas Eastern
Transmission, LP, Algonquin Gas Transmission, LLC, Westcoast Energy Inc. and their respective successors. 
 “Substantial
Assets” means assets (other than Duke Energy International, Inc., Duke Energy North America, LLC and Crescent Resources, LLC) sold or otherwise disposed of in a single transaction or a series of related transactions representing 25% or more
of the consolidated assets of the Borrower and its Consolidated Subsidiaries, taken as a whole. 
 (b) Section 1.01 of the
Agreement is amended by adding the following definitions: 
 “Company” means Duke Energy Corporation, a Delaware
corporation, originally incorporated as Deer Holding Corporation, a Delaware corporation. 
 “Increased Commitments”
has the meaning set forth in Section 2.17. 
 “Permitted Spin-Off” means a distribution of the common equity
interests in the Borrower (or in a parent corporation of the Borrower) (whichever the case, the “Public Company”) to the shareholders of the Company, provided that immediately after giving effect thereto (i) the Borrower
retains United States assets of its natural gas transmission segment comprising not less than 85% of the book value of all such assets at December 31, 2005 and contributing not less than 85% of the United States EBITDA of such segment for the
year then ended and (ii) the Borrower’s senior unsecured long-term debt is rated at least BBB- by S&P and Baa3 by Moody’s. For purposes solely of clause (i) above, the Borrower shall be deemed to own assets which have been
contributed to a master limited partnership or similar entity in exchange for equity interests in such entity, to the extent it retains such equity interests. 
 “Public Company” has the meaning set forth in the definition of Permitted Spin-Off. 

 (c) Section 2.01(a) is amended by deleting the words “Revolving Credit” immediately
preceding “Loans” in the first sentence therof. 
 (d) Section 2.01(b) is amended to read in its entirety as follows:

 (b) Term Loans. Each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make a loan to the
Borrower on its Commitment Termination Date in an amount such that the principal amount of the Loans by such Bank, together with its Letter of Credit Liabilities, shall not exceed its Commitment; provided that no Bank shall be obligated to
make a loan pursuant to this subsection if any Commitment shall have been extended pursuant to Section 2.01(c) to a date later than the Commitment Termination Date of such Bank. Each Borrowing under this Section 2.01(b) shall be made from
the several Banks having the same Commitment Termination Date ratably in proportion to their respective Commitments. 
 (e)
Section 2.01(c) is amended to read in its entirety as follows: 
 (c) Extension of Commitments. The Borrower may, upon
notice to the Administrative Agent not less than 60 days but no more than 90 days prior to any anniversary of the Effective Date, propose to extend the Commitment Termination Dates for an additional one-year period measured from the Commitment
Termination Dates then in effect. The Administrative Agent shall promptly notify the Banks of receipt of such request. Each Bank shall endeavor to respond to such request, whether affirmatively or negatively (such determination in the sole
discretion of such Bank), by notice to the Borrower and the Administrative Agent within 30 days. Subject to the execution by the Borrower, the Administrative Agent and such Banks of a duly completed Extension Agreement in substantially the form of
Exhibit E, the Commitment Termination Date applicable to the Commitment of each Bank so affirmatively notifying the Borrower and the Administrative Agent shall be extended for the period specified above; provided that no Commitment
Termination Date of any Bank shall be extended unless Banks having Commitments in an aggregate amount equal to at least 51% in aggregate amount of the Commitments in effect at the time any such extension is requested shall have elected so to extend
their Commitments. Any Bank which does not give such notice to the Borrower and the Administrative Agent shall be deemed to have elected not to extend as requested, and the Commitment of each non-extending Bank shall terminate on its Commitment
Termination Date determined without giving effect to such requested extension. The Borrower may, in accordance with Section 8.06, designate another bank or other financial institution (which may be, but need not be, an extending Bank) to
replace a non-extending Bank. 
 (f) Section 2.05(c) is amended to read in its entirety as follows: 
 (c) If any provision of any debt instrument or other agreement or instrument binding upon the Borrower, including without limitation this Agreement,
would be contravened by any deposit required hereunder to cash collateralize any Letter of Credit Liabilities, the Borrower shall either (x) obtain a waiver of such provision, (y) prepay the debt incurred under such debt instrument and
terminate such debt instrument or (z) make other arrangements satisfactory to the Required Banks; it being understood and agreed that the risk of any such contravention shall be borne solely by the Borrower and not by the Banks and shall in no
event constitute a defense available to the Borrower for nonperformance of its obligations hereunder. 
 (g) Section 2.15(b) of the
Agreement is amended to read in its entirety as follows: 
 (b) Subject to the terms and conditions hereof, each Continuing LC Issuer
agrees to issue Letters of Credit hereunder from time to time before its Commitment Termination Date upon the request of the Borrower; provided that, immediately after each Letter of Credit is issued, the aggregate amount of the Letter of
Credit Liabilities plus the aggregate outstanding amount of all Loans shall not exceed the aggregate amount of the Commitments. Upon the date of issuance by the Continuing LC Issuer of a Letter of Credit, the Continuing LC Issuer shall be deemed,
without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Continuing LC Issuer, a participation in such Letter of Credit and the
related Letter of Credit Liabilities in the proportion its Commitment bears to the aggregate Commitments; provided that (i) if the scheduled Commitment Termination Date of a Bank falls prior to the expiry date of a Letter of Credit then
outstanding and the Commitments of the other Banks are extended on such date in accordance with Section 2.01(c), such Bank’s participation in such Letter of Credit shall terminate on its Commitment Termination Date, and the participations
of the other Banks therein shall be redetermined pro rata in proportion to their Commitments after giving effect to the termination of the Commitment of such former Bank; and (ii) in the event that the Commitments of the other Banks are not
extended in accordance with Section 2.01(c), then such Bank’s participation in all Letters of Credit shall remain at the level existing prior to the proposed extension, regardless of whether the expiry of any such Letters of Credit extends
beyond such Bank’s Commitment Termination Date. If and to the extent necessary to permit redetermination of the participations in Letters of Credit pursuant to clause (i) of the foregoing proviso within the limits of the Commitments which
are not terminated, the Borrower shall prepay on such date all or a portion of the outstanding Loans and/or secure cancellation of outstanding Letters of Credit, and such redetermination and termination of participations in outstanding Letters of
Credit shall be conditioned upon its having done so. 
  

 2 

 (h) The Agreement is amended by the addition of the following new Section 2.17: 
 Section 2.17. Increase In Commitments; Additional Banks. (a) Subsequent to the Effective Date, the Borrower may, upon at least 30
days’ notice to the Administrative Agent (which shall promptly provide a copy of such notice to the Banks), propose to increase the aggregate amount of the Commitments, provided that after giving effect to any such increase, the total
Commitments shall not exceed $800,000,000 (the amount of any such increase, the “Increased Commitments”). Each Bank party to this Agreement at such time shall have the right (but no obligation), for a period of 15 days following
receipt of such notice, to elect by notice to the Borrower and the Administrative Agent to increase its Commitment hereunder. 
 (b) If
any Bank party to this Agreement shall not elect to increase its Commitment pursuant to subsection (a) of this Section, the Borrower may designate another bank or other lenders (which may be, but need not be, one or more of the existing Banks)
which at the time agree to (i) in the case of any such lender that is an existing Bank, increase its Commitment and (ii) in the case of any other such lender (an “Additional Bank”), become a party to this Agreement. The
sum of the increases in the Commitments of the existing Banks pursuant to this subsection (b) plus the Commitments of the Additional Banks shall not in the aggregate exceed the unsubscribed amount of the Increased Commitments. 
 (c) An increase in the aggregate amount of the Commitments pursuant to this Section 2.17 shall become effective upon the receipt by the
Administrative Agent of an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrower, by each Additional Bank and by each other Bank whose Commitment is to be increased, setting forth the new Commitments of such
Banks and setting forth the agreement of each Additional Bank to become a party to this Agreement and to be bound by all the terms and provisions hereof, together with such evidence of appropriate corporate authorization on the part of the Borrower
with respect to the Increased Commitments and such opinions of counsel for the Borrower with respect to the Increased Commitments as the Administrative Agent may reasonably request. 
 Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.17, (i) the respective Letter of Credit
Liabilities of the Banks shall be redetermined as of the effective date of such increase and (ii) within five Domestic Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with
respect thereto, in the case of any Euro-Dollar Loans then outstanding, the Borrower shall prepay such Group of Loans in its entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in Article 3, the Borrower
shall reborrow Revolving Credit Loans from the Banks in proportion to their respective Commitments after giving effect to such increase, until such time as all outstanding Revolving Credit Loans are held by the Banks in such proportion. 

(i) Section 3.02 of the Agreement is amended by adding the phrase “or issuance” immediately following the phrase “such
Borrowing” in the last sentence thereof. 
 (j) Section 4.04(a) of the Agreement is amended by changing the date specified

issuance of Letters of Credit will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock. 
 (n) Article 4 of the Agreement is amended by deleting Section 4.09 thereof in its entirety. 
 (o) Section 4.06 of the Agreement is amended by changing the phrase “reports referred to in Section 4.04” to

 (p) Section 5.08(a) of the Agreement is amended by changing the date specified therein from “June 30, 2005” to “June 29,
2006”. 
 (q) Section 5.11 of the Agreement is amended (i) by changing each reference therein to “Duke Energy
Corporation” to “Duke Power Company LLC and/or Cinergy Corp.” and (ii) changing the figure “$200,000,000” to “$500,000,000”.

Subsidiary of the Company; except pursuant to a Permitted Spin-Off; or (ii) subsequent to a Permitted Spin-Off: (x) any person or group of persons (within the meaning of Section 13 or 14 of the Exchange Act) other than trustees and
participants in employee benefit plans of the Public Company and its Subsidiaries or the Endowment or Trust, shall have acquired beneficial ownership (within the meaning of Rule 13d-3 promulgated by the Securities and Exchange Commission under the
Exchange Act) of 50% or more of the outstanding shares of common stock of the Public Company; (y) during any period of twelve consecutive calendar months commencing on or after the date of the Permitted Spin-Off, individuals who were directors

giving notice thereof to the Banks and the Borrower. Upon any such resignation,(i) the Borrower, with the consent of the Required Banks (such consent not to be unreasonably withheld or delayed), or (ii) if an Event of Default has occurred and
is continuing, then the Required Banks, shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment, within 30 days after the retiring
Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United
States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder; provided that if such
successor Administrative Agent is appointed without the consent of the Borrower, such successor Administrative Agent may be replaced by the Borrower with the consent of the Required Banks so long as no Event of Default has occurred and is continuing
at the time. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative
Agent. 
 (u) Article 8 of the Agreement is amended by deleting Section 8.03(c) thereof in its entirety. 
 (v) The last sentence of Section 8.06(b) of the Agreement is amended to read as follows: 
 Upon satisfaction of the foregoing conditions, the Commitment of such Bank shall terminate on the effective date specified in such notice, its
participation in any outstanding Letters of Credit shall terminate on such effective date and the participations of the other Banks therein shall be redetermined as of such date as if such Letters of Credit had been issued on such date. 

(w) The Pricing Schedule attached hereto replaces the Pricing Schedule attached to the Agreement. 
 SECTION 4. Change in Commitments. (a) With effect from and including the date this Amendment and Restatement becomes effective in accordance with

Commitment of each Bank shall be the amount set forth opposite the name of such Bank on the attached Commitment Schedule, which shall become the Commitment Schedule referred to in the Agreement. Any Bank under the Agreement not listed on such

be due and payable on such date; provided that the provisions of Sections 8.03, 8.04 and 9.03 of the Agreement shall continue to inure to the benefit of each Departing Bank.

 4

warrants that as of the date hereof and after giving effect hereto: 
 (a) no Default has occurred and is continuing; and 
 (b) each representation and warranty of the Borrower set forth in the Agreement after giving effect to this Amendment and Restatement is true and
correct as though made on and as of such date. 
 SECTION 6. Governing Law. This Amendment and Restatement shall be governed by and
construed in accordance with the laws of the State of New York. 
 SECTION 7. Counterparts; Effectiveness. This Amendment and Restatement
may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Amendment and Restatement shall become effective as of the date hereof
when each of the following conditions shall have been satisfied: 
 (i) receipt by the Administrative Agent of duly executed
counterparts hereof signed by each of the parties listed on the signature pages hereof (or, in the case of any party as to which an executed counterpart shall not have been received, the Administrative Agent shall have received telegraphic, telex or
other written confirmation from such party of execution of a counterpart hereof by such party); 
 (ii) receipt by the Administrative
Agent of an opinion of such counsel for the Borrower as may be acceptable to the Administrative Agent, substantially to the effect of Exhibits B-1 and B-2 to the Agreement with reference to this Amendment and Restatement and the Agreement as amended
and restated hereby;

 The Euro-Dollar Margin for any
Term Loan shall equal the sum of (i) the rate that would otherwise be in effect based upon the table above and (ii) 12.5 basis points. 
 The
“Utilization” applicable to any date is the percentage equivalent of a fraction the numerator of which is the sum of (i) the aggregate outstanding principal amount of the Loans determined at such time after giving effect, if
one or more Loans are being made at such time, to any substantially concurrent application of the proceeds thereof to repay one or more other Loans plus (ii) the aggregate amount of the Letter of Credit Liabilities of all Banks at such time and
the denominator of which is the aggregate amount of the Commitments at such date. If for any reason any Loans or Letter of Credit Liabilities remain outstanding following termination of the Commitments, Utilization will be deemed to be 100%.

 The credit ratings to be utilized for purposes of this Schedule are those indicated for or assigned to the senior unsecured long-term debt securities
of the Borrower without third-party credit enhancement, and any rating indicated for or assigned to any other debt security of the Borrower shall be disregarded. The ratings in effect for any day are those in effect at the close of business on such
day. A change in credit rating will result in an immediate change in the applicable pricing. In the case of split ratings from S&P and Moody’s, the rating to be used to determine the applicable pricing is a rating one notch higher than the
lower of the two.Amended and Restated Credit Agreement

 ARTICLE 2 
 THE CREDITS 
  
 Section 2.01.
Commitments to Lend. (a) Revolving Credit Loans. During its Revolving Credit Period, each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make loans to the Borrower pursuant to this subsection from
time to time in amounts such that the aggregate principal amount of Loans by such Bank, together with its Letter of Credit Liabilities, at any one time outstanding shall not exceed the amount of its Commitment. Each Borrowing under this subsection
shall be in an aggregate principal amount of $10,000,000 or any larger multiple of $1,000,000 (except that any such Borrowing may be in the aggregate amount available in accordance with Section 3.02(b)) and shall be made from the several Banks
ratably in proportion to their respective Commitments in effect on the date of Borrowing; provided that, if the Interest Period selected by the Borrower for a Borrowing would otherwise end after the Commitment Termination Dates of some but
not all Banks, the Borrower may in its Notice of Borrowing elect not to borrow from those Banks whose Commitment Termination Dates fall prior to the end of such Interest Period. Within the foregoing limits, the Borrower may borrow under this
subsection (a), or to the extent permitted by Section 2.11, prepay Loans and reborrow at any time during the Revolving Credit Periods under this subsection (a). 
 (b) Term Loans. Each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make a loan to the Borrower on its
Commitment Termination Date in an amount such that the principal amount of the Loans by such Bank, together with its Letter of Credit Liabilities, shall not exceed its Commitment; provided that no Bank shall be obligated to make a loan
pursuant to this subsection if any Commitment shall have been extended pursuant to Section 2.01(c) to a date later than the Commitment Termination Date of such Bank. Each Borrowing under this Section 2.01(b) shall be made from the several
Banks having the same Commitment Termination Date ratably in proportion to their respective Commitments. 
 (c) Extension of
Commitments. The Borrower may, upon notice to the Administrative Agent not less than 60 days but no more than 90 days prior to any anniversary of the Effective Date, propose to extend the Commitment Termination Dates for an additional one-year
period measured from the Commitment Termination Dates then in effect. The Administrative Agent shall promptly notify the Banks of receipt of such request. Each Bank shall endeavor to respond to such request, whether affirmatively or negatively (such
determination in the sole discretion of such Bank), by notice to the Borrower and the Administrative Agent within 30 days. Subject to the execution by the Borrower, the Administrative Agent and such Banks of a duly completed Extension Agreement in
substantially the form of Exhibit E, the Commitment Termination Date applicable to the Commitment of each Bank so affirmatively notifying the Borrower and the Administrative Agent shall be extended for the period specified above; provided
that no Commitment Termination Date of any Bank shall be extended unless Banks having Commitments in an aggregate amount equal to at least 51% in aggregate amount of the Commitments in effect at the time any such extension is requested shall have
elected so to extend their Commitments. Any Bank which does not give such notice to the Borrower and the Administrative Agent shall be deemed to have elected not to extend as requested, and the Commitment of each non-extending Bank shall terminate
on its Commitment Termination Date determined without giving effect to such requested extension. The Borrower may, in accordance with Section 8.06, designate another bank or other financial institution (which may be, but need not be, an
extending Bank) to replace a non-extending Bank. 
 Section 2.02. Notice of Borrowings. The Borrower shall give the Administrative Agent
notice (a “Notice of Borrowing”) not later than 11:00 A.M. (New York City time) on (x) the date of each Base Rate Borrowing and (y) the third Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying:

 (a) the date of such Borrowing, which shall be a Domestic Business Day in the case of a Domestic Borrowing or a Euro-Dollar Business
Day in the case of a Euro-Dollar Borrowing; 
 (b) the aggregate amount of such Borrowing; 
 (c) whether the Loans comprising such Borrowing are to bear interest initially at the Base Rate or a Euro-Dollar Rate; and 
 (d) in the case of a Euro-Dollar Borrowing, the duration of the initial Interest Period applicable thereto, subject to the provisions of the
definition of Interest Period. 
 Section 2.03. Notice to Banks; Funding of Loans. (a) Upon receipt of a Notice of Borrowing,
the Administrative Agent shall promptly notify each Bank of the contents thereof and of such Bank’s share (if any) of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Borrower. 
 (b) Not later than 1:00 P.M. (New York City time) on the date of each Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address specified in or pursuant to Section 9.01. Unless the
Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Banks available to the Borrower at the Administrative Agent’s
aforesaid address. 
 (c) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Borrowing that
such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such 

  

 6 

 
Bank has made such share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (b) of this Section 2.03 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 such Bank shall not have so made such share available to the Administrative Agent, such Bank
and, if such Bank shall not have made such payment within two Domestic Business Days of demand therefor, the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and
the interest rate applicable thereto pursuant to Section 2.06 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute
such Bank’s Loan included in such Borrowing for purposes of this Agreement. 
 (d) The failure of any Bank to make the Loan to be
made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make a Loan on the date of such Borrowing, but no Bank shall be responsible for the failure of any other Bank to make a Loan to be made by
such other Bank. 
 Section 2.04. Registry; Notes. (a) The Administrative Agent shall maintain a register (the
“Register”) on which it will record the Commitment of each Bank, each Loan made by such Bank and each repayment of any Loan made by such Bank. Any such recordation by the Administrative Agent on the Register shall be conclusive,
absent manifest error. Failure to make any such recordation, or any error in such recordation, shall not affect the Borrower’s obligations hereunder. 
 (b) The Borrower hereby agrees that, promptly upon the request of any Bank at any time, the Borrower shall deliver to such Bank a duly executed Note, in substantially the form of Exhibit A hereto, payable to the order of such
Bank and representing the obligation of the Borrower to pay the unpaid principal amount of the Loans made to the Borrower by such Bank, with interest as provided herein on the unpaid principal amount from time to time outstanding. 
 (c) Each Bank shall record the date, amount and maturity of each Loan made by it and the date and amount of each payment of principal made by the
Borrower with respect thereto, and each Bank receiving a Note pursuant to this Section, if such Bank so elects in connection with any transfer or enforcement of its Note, may endorse on the schedule forming a part thereof appropriate notations to
evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of such Bank to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the
Notes. Such Bank is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required. 
 Section 2.05. Maturity of Loans; Effect of Cash Collateralization of Letters of Credit. (a) Each Revolving Credit Loan made by any Bank
shall mature, and the principal amount thereof shall be due and payable together with accrued interest thereon, on the Commitment Termination Date of such Bank. 
 (b) The Term Loan of each Bank shall mature, and the principal amount thereof shall be due and payable, together with accrued interest thereon, on
the Final Maturity Date. 
 (c) If any provision of any debt instrument or other agreement or instrument binding upon the Borrower,
including without limitation this Agreement, would be contravened by any deposit required hereunder to cash collateralize any Letter of Credit Liabilities, the Borrower shall either (x) obtain a waiver of such provision, (y) prepay the
debt incurred under such debt instrument and terminate such debt instrument or (z) make other arrangements satisfactory to the Required Banks; it being understood and agreed that the risk of any such contravention shall be borne solely by the
Borrower and not by the Banks and shall in no event constitute a defense available to the Borrower for nonperformance of its obligations hereunder. 
 Section 2.06. Interest Rates. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made until it becomes due, at a rate per annum equal to
the Base Rate for such day. Such interest shall be payable quarterly in arrears on each Quarterly Payment Date, at maturity and on the date of termination of the Commitments in their entirety. Any overdue principal of or overdue interest on any Base
Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 1% plus the Base Rate for such day. 
 (b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such day
plus the London Interbank Offered Rate applicable to such Interest Period. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after
the first day thereof. 
 The “London Interbank Offered Rate” applicable to any Interest Period means the rate appearing on Page 3750
of the Telerate Service Company (or on any successor or substitute page of such service, or any successor to or substitute for such service, providing rate quotations comparable to those currently provided on such page of the Telerate Service, as
may be nominated by the British Bankers’ Association for purposes of providing quotations of interest rates applicable to dollar deposits in the London interbank market) as of 

  

 7 

 
11:00 A.M. (London time) two Euro-Dollar Business Days prior to the commencement of such Interest Period, as the rate for dollar deposits with a maturity comparable to
such Interest Period. In the event that such rate is not so available at such time for any reason, then the “London Interbank Offered Rate” for such Interest Period shall be the average (rounded upward, if necessary, to the next
higher 1/16 of 1%) of the respective rates per annum at which deposits in dollars are offered to each of the Euro-Dollar Reference Banks in the London interbank market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before
the first day of such Interest Period in an amount approximately equal to the principal amount of the Loan of such Euro-Dollar Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. If
any Euro-Dollar Reference Bank does not furnish a timely quotation, the Administrative Agent shall determine the relevant interest rate on the basis of the quotation furnished by the remaining Euro-Dollar Reference Bank or, if none of such
quotations is available on a timely basis, the provisions of Section 8.01 shall apply. 
 (c) Any overdue principal of or overdue
interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 1% plus the higher of
(i) the sum of the Euro-Dollar Margin for such day plus the London Interbank Offered Rate applicable to such Loan at the date such payment was due and (ii) the Base Rate for such day. 
 (d) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice
to the Borrower and the participating Banks by telecopy, telex or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error unless the Borrower raises an objection thereto within
five Domestic Business Days after receipt of such notice. 
 Section 2.07. Fees. (a) Facility Fee. The Borrower shall pay to the
Administrative Agent for the account of each Bank a facility fee at the Facility Fee Rate (determined daily in accordance with the Pricing Schedule). Such facility fee shall accrue (i) from and including the Effective Date to but excluding such
Bank’s Commitment Termination Date, on the daily average aggregate amount of such Bank’s Commitment (whether used or unused) and (ii) from and including such Bank’s Commitment Termination Date to but excluding the date such
Bank’s Loans and Letter of Credit Liabilities shall be repaid in their entirety, on the daily average aggregate outstanding principal amount of such Bank’s Loans and Letter of Credit Liabilities. 
 (b) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent (i) for the account of the Banks ratably a letter of
credit fee accruing daily on the aggregate amount then available for drawing under all outstanding Letters of Credit at a rate per annum equal to the then applicable Euro-Dollar Margin and (ii) for the account of each Issuing Bank a letter of
credit fronting fee accruing daily on the aggregate amount then available for drawing under all Letters of Credit issued by such Issuing Bank at a rate per annum of 0.125% (or such other rate as may be mutually agreed from time to time by the
Borrower and such Issuing Bank). 
 (c) Payments. Accrued fees under this Section for the account of any Bank shall be payable
quarterly in arrears on each Quarterly Payment Date and upon such Bank’s Commitment Termination Date and Final Maturity Date (and, if later, the date the Loans and Letter of Credit Liabilities of such Bank shall be repaid in their entirety).

 Section 2.08. Optional Termination or Reduction of Commitments. The Borrower may, upon at least three Domestic Business Days’ notice
to the Administrative Agent, (i) terminate the Commitments at any time, if no Loans or Letter of Credit Liabilities are outstanding at such time, or (ii) ratably reduce from time to time by an aggregate amount of $10,000,000 or any larger
multiple of $1,000,000 the aggregate amount of the Commitments in excess of the aggregate outstanding principal amount of the Loans and Letter of Credit Liabilities. 
 Section 2.09. Method of Electing Interest Rates. (a) The Loans included in each Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of
Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article 8 and the last sentence of this subsection (a)), as
follows: 
 (i) if such Loans are Base Rate Loans, the Borrower may elect to convert such Loans to Euro-Dollar Loans as of any
Euro-Dollar Business Day; and 
 (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate
Loans or elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period, subject to Section 2.13 in the case of any such conversion or continuation effective on any day other than the last day of the then current Interest
Period applicable to such Loans. 
 Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the
Administrative Agent not later than 11:00 A.M. (New York City time) on the third Euro-Dollar Business Day before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such notice applies,
and the remaining portion to which it does not apply, are each $10,000,000 or any larger multiple of $1,000,000. 
  

 8 

 (b) Each Notice of Interest Rate Election shall specify: 
 (i) the Group of Loans (or portion thereof) to which such notice applies; 
 (ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of
subsection 2.09(a) above; 
 (iii) if the Loans comprising such Group are to be converted, the new type of Loans and, if the Loans being
converted are to be Euro-Dollar Loans, the duration of the next succeeding Interest Period applicable thereto; and 
 (iv) if such Loans
are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period. 
 Each Interest Period specified in a
Notice of Interest Rate Election shall comply with the provisions of the definition of the term “Interest Period”. 
 (c) Promptly after receiving a Notice of Interest Rate Election from the Borrower pursuant to subsection 2.09(a) above, the Administrative Agent shall notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower. If no Notice of Interest Rate Election is timely received prior to the end of an Interest Period for any Group of Loans, the Borrower shall be deemed to have elected that such Group of Loans be converted to Base Rate Loans
as of the last day of such Interest Period. 
 (d) An election by the Borrower to change or continue the rate of interest applicable to
any Group of Loans pursuant to this Section shall not constitute a “Borrowing” subject to the provisions of Section 3.02. 
 Section 2.10. Mandatory Termination of Commitments. The Commitment of each Bank shall terminate on such Bank’s Commitment Termination Date, and any Revolving Credit Loans of such Bank then outstanding (together with accrued
interest thereon) shall be due and payable on such date. 
 Section 2.11. Optional Prepayments. (a) The Borrower may
(i) upon notice to the Administrative Agent not later than 11:00 A.M. (New York City time) on any Domestic Business Day prepay on such Domestic Business Day any Group of Base Rate Loans and (ii) upon at least three Euro-Dollar Business
Days’ notice to the Administrative Agent not later than 11:00 A.M. (New York City time) prepay any Group of Euro-Dollar Loans, in each case in whole at any time, or from time to time in part in amounts aggregating $5,000,000 or any larger
multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment and together with any additional amounts payable pursuant to Section 2.13. Each such optional prepayment shall
be applied to prepay ratably the Loans of the several Banks included in such Group or Borrowing. 
 (b) Upon receipt of a notice of
prepayment pursuant to this Section, the Administrative Agent shall promptly notify each Bank of the contents thereof and of such Bank’s share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower.

 Section 2.12. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on,
the Loans and of fees hereunder, not later than 1:00 P.M. (New York City time) on the date when due, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address referred to in Section 9.01 and
without reduction by reason of any set-off, counterclaim or deduction of any kind. The Administrative Agent will promptly distribute to each Bank in like funds its ratable share of each such payment received by the Administrative Agent for the
account of the Banks. Whenever any payment of principal of, or interest on, the Base Rate Loans or Letter of Credit Liabilities or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to
the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next
succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is
extended by operation of law or otherwise, interest thereon shall be payable for such extended time. 
 (b) Unless the Administrative
Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment
in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to
such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate. 
 Section 2.13. Funding Losses.
If the Borrower makes any payment of principal with respect to any Euro-Dollar Loan or any Euro-Dollar Loan is converted to a Base Rate Loan or continued as a Euro-Dollar Loan for a new Interest Period (pursuant to Article 2, 6 or 8 or
otherwise) on any day other than the last day of an Interest Period applicable thereto, or if the Borrower fails to borrow, prepay, convert 

  

 9 

 
or continue any Euro-Dollar Loans after notice has been given to any Bank in accordance with Section 2.03(a), 2.09(c) or 2.11(b), the Borrower shall reimburse
each Bank within 15 days after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing
deposits from third parties, but excluding loss of margin for the period after any such payment or conversion or failure to borrow, prepay, convert or continue; provided that such Bank shall have delivered to the Borrower a certificate
setting forth in reasonable detail the calculation of the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error. 
 Section 2.14. Computation of Interest and Fees. Interest based on the Base Rate and facility fees hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual
number of days elapsed (including the first day but excluding the last day). All other interest and Letter of Credit fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day
but excluding the last day). 
 Section 2.15. Letters of Credit. 
 (a) Subject to the terms and conditions hereof, each Issuing Bank agrees to issue Letters of Credit hereunder from time to time before its
Commitment Termination Date upon the request of the Borrower; provided that, immediately after each Letter of Credit is issued, (i) the aggregate amount of the Letter of Credit Liabilities plus the aggregate outstanding principal amount
of the Revolving Credit Loans shall not exceed the aggregate amount of the Commitments and (ii) the aggregate amount of the Letter of Credit Liabilities shall not exceed $250,000,000. Upon the date of issuance by the Issuing Bank of a Letter of
Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation in
such Letter of Credit and the related Letter of Credit Liabilities in the proportion its Commitment bears to the aggregate Commitments; provided that (i) if the scheduled Commitment Termination Date of a Bank falls prior to the expiry
date of a Letter of Credit then outstanding and the Commitments of the other Banks are extended on such date in accordance with Section 2.01(c), such Bank’s participation in such Letter of Credit shall terminate on its Commitment
Termination Date, and the participations of the other Banks therein shall be redetermined pro rata in proportion to their Commitments after giving effect to the termination of the Commitment of such former Bank; and (ii) in the event that the
Commitments of the other Banks are not extended in accordance with Section 2.01(c), then such Bank’s participation in all Letters of Credit shall remain at the level existing prior to the proposed extension, regardless of whether the
expiry of any such Letters of Credit extends beyond such Bank’s Commitment Termination Date. If and to the extent necessary to permit redetermination of the participations in Letters of Credit pursuant to clause (i) of the foregoing
proviso within the limits of the Commitments which are not terminated, the Borrower shall prepay on such date all or a portion of the outstanding Loans and/or secure cancellation of outstanding Letters of Credit, and such redetermination and
termination of participations in outstanding Letters of Credit shall be conditioned upon its having done so. 
 (b) The Borrower shall
give the Issuing Bank notice at least three Domestic Business Days prior to the requested issuance of a Letter of Credit, or in the case of a Letter of Credit substantially in the form of Exhibit G, at least one Business Day prior to the requested
issuance of such Letter of Credit, specifying the date such Letter of Credit is to be issued and describing the terms of such Letter of Credit (such notice, including any such notice given in connection with the extension of a Letter of Credit, a
“Notice of Issuance”), substantially in the form of Exhibit F, appropriately completed. Upon receipt of a Notice of Issuance, the Issuing Bank shall promptly notify the Administrative Agent, and the Administrative Agent shall
promptly notify each Bank of the contents thereof and of the amount of such Bank’s participation in such Letter of Credit. The issuance by the Issuing Bank of each Letter of Credit shall, in addition to the conditions precedent set forth in
Article 3, be subject to the conditions precedent that such Letter of Credit shall be denominated in U.S. dollars and shall be in such form and contain such terms as shall be reasonably satisfactory to the Issuing Bank. Unless otherwise notified by
the Administrative Agent, the Issuing Bank may, but shall not be required to, conclusively presume that all conditions precedent set forth in Article 3 have been satisfied. The Borrower shall also pay to each Issuing Bank for its own account
issuance, drawing, amendment and extension charges in the amounts and at the times as agreed between the Borrower and such Issuing Bank. Except for non-substantive amendments to any Letter of Credit for the purpose of correcting errors or
ambiguities or to allow for administrative convenience (which amendments each Issuing Bank may make in its discretion with the consent of the Borrower), the amendment, extension or renewal of any Letter of Credit shall be deemed to be an issuance of
such Letter of Credit. If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination is given by the Issuing Bank of such Letter of Credit, the Issuing Bank shall timely
give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which the Issuing Bank’s notice of termination may be given to the beneficiaries of such Letter of Credit, the Issuing Bank has
received a notice of termination from the Borrower or a notice from the Administrative Agent that the conditions to issuance of such Letter of Credit have not been satisfied or (ii) the renewed Letter of Credit would have a term not permitted
by subsection (c) below. 
 (c) No Letter of Credit shall have a term extending beyond the first anniversary of the Commitment
Termination Date of the applicable Issuing Bank. 
  

 10 

 (d) Upon receipt from the beneficiary of any applicable Letter of Credit of any notice of a drawing
under such Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Bank as to the amount to be paid as a result of such demand or drawing and the payment
date. The Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank upon any drawing under any Letter of Credit without presentment, demand, protest or other
formalities of any kind. All such amounts paid by the Issuing Bank and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate for such day plus, if such amount
remains unpaid for more than two Domestic Business Days, 1%. In addition, each Bank will pay to the Administrative Agent, for the account of the applicable Issuing Bank, immediately upon such Issuing Bank’s demand at any time during the period
commencing after such drawing until reimbursement therefor in full by the Borrower, an amount equal to such Bank’s ratable share of such drawing (in proportion to its participation therein), together with interest on such amount for each day
from the date of the Issuing Bank’s demand for such payment (or, if such demand is made after 12:00 Noon (New York City time) on such date, from the next succeeding Domestic Business Day) to the date of payment by such Bank of such amount at a
rate of interest per annum equal to the Federal Funds Rate and, if such amount remains unpaid for more than five Domestic Business Days after the Issuing Bank’s demand for such payment, at a rate of interest per annum equal to the Base Rate
plus 1%. The Issuing Bank will pay to each Bank ratably all amounts received from the Borrower for application in payment of its reimbursement obligations in respect of any Letter of Credit, but only to the extent such Bank has made payment to the
Issuing Bank in respect of such Letter of Credit pursuant hereto. 
 (e) The obligations of the Borrower and each Bank under subsection
2.15(d) above shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following circumstances: 

(i) the use which may be made of the Letter of Credit by, or any acts or omission of, a beneficiary of a Letter of Credit (or any Person for whom
the beneficiary may be acting); 
 (ii) the existence of any claim, set-off, defense or other rights that the Borrower may have at any
time against a beneficiary of a Letter of Credit (or any Person for whom the beneficiary may be acting), the Banks (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document
related hereto or thereto or any unrelated transaction; 
 (iii) any statement or any other document presented under a Letter of Credit
proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; 
 (iv) payment under a Letter of Credit to the beneficiary of such Letter of Credit against presentation to the Issuing Bank of a draft or certificate that does not comply with the terms of the Letter of Credit; provided that the
determination by the Issuing Bank to make such payment shall not have been the result of its willful misconduct or gross negligence; or 
 (v) any other act or omission to act or delay of any kind by any Bank (including the Issuing Bank), the Administrative Agent or any other Person or any other event or circumstance whatsoever that might, but for the provisions of this
subsection (v), constitute a legal or equitable discharge of the Borrower’s or the Bank’s obligations hereunder. 
 (f) The
Borrower hereby indemnifies and holds harmless each Bank (including the Issuing Bank) and the Administrative Agent from and against any and all claims, damages, losses, liabilities, costs or expenses which such Bank or the Administrative Agent may
incur (including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the Issuing Bank may incur by reason of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to
such Issuing Bank hereunder (but nothing herein contained shall affect any rights the Borrower may have against such defaulting Bank) or (ii) any litigation arising with respect to this Agreement (whether or not the Issuing Bank shall prevail
in such litigation)), and none of the Banks (including the Issuing Bank) nor the Administrative Agent nor any of their officers or directors or employees or agents shall be liable or responsible, by reason of or in connection with the execution and
delivery or transfer of or payment or failure to pay under any Letter of Credit, including without limitation any of the circumstances enumerated in subsection 2.15(e) above, as well as (i) any error, omission, interruption or delay in
transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, (ii) any loss or delay in the transmission of any document required in order to make a drawing under a Letter of Credit and (iii) any consequences
arising from causes beyond the control of the Issuing Bank, including, without limitation, any government acts or any other circumstances whatsoever, in making or failing to make payment under such Letter of Credit; provided that the Borrower
shall not be required to indemnify the Issuing Bank for any claims, damages, losses, liabilities, costs or expenses, and the Borrower shall have a claim for direct (but not consequential) damage suffered by it, to the extent found by a court of
competent jurisdiction to have been caused by (x) the willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or
(y) the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of the Letter of Credit. Nothing in this subsection 2.15(f) is intended to limit
the obligations of 

  

 11 

 
the Borrower under any other provision of this Agreement. To the extent the Borrower does not indemnify the Issuing Bank as required by this subsection, the Banks
agree to do so ratably in accordance with their Commitments. 
 (g) The Issuing Bank shall act on behalf of the Banks with respect to
any Letters of Credit issued by it and the documents associated therewith, and the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in Article 7 (other than Sections 7.08 and 7.09) with respect
to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as
if the term “Administrative Agent” as used in Article 7 included the Issuing Bank with respect to such acts or omissions and (ii) as additionally provided herein with respect to the Issuing Bank. 
 Section 2.16. Regulation D Compensation. In the event that a Bank is required to maintain reserves of the type contemplated by the definition of
“Euro-Dollar Reserve Percentage”, such Bank may require the Borrower to pay, contemporaneously with each payment of interest on the Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such Bank at a rate per
annum determined by such Bank up to but not exceeding the excess of (i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank
Offered Rate. Any Bank wishing to require payment of such additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Bank shall be payable to such
Bank at the place indicated in such notice with respect to each Interest Period commencing at least three Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least three Euro-Dollar Business Days prior
to each date on which interest is payable on the Euro-Dollar Loans of the amount then due it under this Section. Each such notification shall be accompanied by such information as the Borrower may reasonably request. 
 “Euro-Dollar Reserve Percentage” means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for determining the maximum reserve requirement for a member bank of the Federal Reserve System in New York City with deposits exceeding five billion dollars in respect of
“Eurocurrency liabilities” (or in respect of any other category of liabilities which includes deposits by reference to which the interest rate on Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United States residents). 
 Section 2.17. Increase In Commitments;
Additional Banks. (a) Subsequent to the Effective Date, the Borrower may, upon at least 30 days’ notice to the Administrative Agent (which shall promptly provide a copy of such notice to the Banks), propose to increase the aggregate
amount of the Commitments, provided that after giving effect to any such increase, the total Commitments shall not exceed $700,000,000 (the amount of any such increase, the “Increased Commitments”). Each Bank party to this
Agreement at such time shall have the right (but no obligation), for a period of 15 days following receipt of such notice, to elect by notice to the Borrower and the Administrative Agent to increase its Commitment hereunder. 
 (b) If any Bank party to this Agreement shall not elect to increase its Commitment pursuant to subsection (a) of this Section, the Borrower may
designate another bank or other lenders (which may be, but need not be, one or more of the existing Banks) which at the time agree to (i) in the case of any such lender that is an existing Bank, increase its Commitment and (ii) in the case
of any other such lender (an “Additional Bank”), become a party to this Agreement. The sum of the increases in the Commitments of the existing Banks pursuant to this subsection (b) plus the Commitments of the Additional Banks
shall not in the aggregate exceed the unsubscribed amount of the Increased Commitments. 
 (c) An increase in the aggregate amount of
the Commitments pursuant to this Section 2.17 shall become effective upon the receipt by the Administrative Agent of an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrower, by each Additional Bank and
by each other Bank whose Commitment is to be increased, setting forth the new Commitments of such Banks and setting forth the agreement of each Additional Bank to become a party to this Agreement and to be bound by all the terms and provisions
hereof, together with such evidence of appropriate corporate authorization on the part of the Borrower with respect to the Increased Commitments and such opinions of counsel for the Borrower with respect to the Increased Commitments as the
Administrative Agent may reasonably request. 
 Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.17, (i) the respective
Letter of Credit Liabilities of the Banks shall be redetermined as of the effective date of such increase and (ii) within five Domestic Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current
Interest Period with respect thereto, in the case of any Euro-Dollar Loans then outstanding, the Borrower shall prepay such Group of Loans in its entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in
Article 3, the Borrower shall reborrow Revolving Credit Loans from the Banks in proportion to their respective Commitments after giving effect to such increase, until such time as all outstanding Revolving Credit Loans are held by the Banks in such
proportion.

 ARTICLE 7 
 THE ADMINISTRATIVE AGENT 
  
 Section 7.01. Appointment and Authorization. Each Bank irrevocably appoints and authorizes the Administrative Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement and the Notes as are delegated to the Administrative Agent by the terms hereof or thereof, together with all such powers as are reasonably incidental thereto. 
 Section 7.02. Administrative Agent and Affiliates. Citibank, N.A. shall have the same rights and powers under this Agreement as any other Bank and may
exercise or refrain from exercising the same as though it were not the Administrative Agent, and Citibank, N.A. and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any
Subsidiary or affiliate of the Borrower as if it were not the Administrative Agent hereunder. 
 Section 7.03. Action by Administrative Agent.
The obligations of the Administrative Agent hereunder are only those expressly set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default,
except as expressly provided in Article 6. 
 Section 7.04. Consultation with Experts. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel,
accountants or experts. 
 Section 7.05. Liability of Administrative Agent. Neither the Administrative Agent nor any of its affiliates nor
any of their respective directors, officers, agents or employees shall be liable to any Bank for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Banks or (ii) in the absence
of its own gross negligence or willful misconduct. Neither the Administrative Agent nor any of its affiliates nor any of their respective directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with this Agreement or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower; (iii) the
satisfaction of any condition specified in Article 3, except receipt of items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness or genuineness of this Agreement, the Notes or any other instrument or
writing furnished in connection herewith. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) believed
by it in good faith to be genuine or to be signed by the proper party or parties. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative
relationship between independent contracting parties. 
 Section 7.06. Indemnification. Each Bank shall, ratably in accordance with its
Commitment, indemnify the Administrative Agent, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct) that such indemnitees may suffer or incur in connection with this Agreement or any action taken or omitted by such
indemnitees thereunder. 
 Section 7.07. Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon any
Agent or any other Bank, 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 Bank also acknowledges that it will, independently and without reliance
upon any Agent or any other Bank, 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 any action under this Agreement. 
 Section 7.08. Successor Administrative Agent. The Administrative Agent may resign at any time by giving notice thereof to the Banks and the Borrower.
Upon any such resignation,(i) the Borrower, with the consent of the Required Banks (such consent not to be unreasonably withheld or delayed), or (ii) if an Event of Default has occurred and is continuing, then the Required Banks, shall have the
right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed, and shall have 

  

 19 

 
accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000.
Upon the acceptance of its appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder; provided that if such successor Administrative Agent is appointed without the consent of the Borrower, such successor
Administrative Agent may be replaced by the Borrower with the consent of the Required Banks so long as no Event of Default has occurred and is continuing at the time. After any retiring Administrative Agent’s resignation hereunder as
Administrative Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent. 
 Section 7.09. Administrative Agent’s Fee. The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon between the Borrower and the
Administrative Agent. 
 Section 7.10. Other Agents. None of the Syndication Agent or the Documentation Agents, in their capacity as such,
shall have any duties or obligations of any kind under this Agreement. 
  
 ARTICLE 8 
 CHANGE IN CIRCUMSTANCES 
  
 Section 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest
Period for any Euro-Dollar Borrowing: 
 (a) the Administrative Agent is advised by the Euro-Dollar Reference Banks that deposits in
dollars (in the applicable amounts) are not being offered to the Euro-Dollar Reference Banks in the relevant market for such Interest Period, or 
 (b) Banks having 66 2/3% or more of the aggregate amount of the affected Loans advise the
Administrative Agent that the London Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Euro-Dollar Loans for such Interest Period, 
 the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the
circumstances giving rise to such suspension no longer exist, (i) the obligations of the Banks to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each outstanding
Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least one Domestic Business Day before the date of any
Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing. 
 Section 8.02. Illegality. If on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank
(or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office)
to make, maintain or fund any of its Euro-Dollar Loans and such Bank shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower, whereupon until such Bank notifies the
Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank to make Euro-Dollar Loans, or to continue or convert outstanding Loans as or into Euro-Dollar Loans, shall be
suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not be otherwise
disadvantageous to such Bank in the good faith exercise of its discretion. If such notice is given, each Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current
Interest Period applicable to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund such Loan to such day or (b) immediately if such Bank shall determine that it may not lawfully continue to maintain and fund such Loan
to such day. 
 Section 8.03. Increased Cost and Reduced Return. (a) If on or after the date of this Agreement, the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (the terms “Bank” and “Issuing Bank” shall include, for purposes of this Section 8.03, the holding company of any Issuing Bank) (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law) issued on or after such date of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve, special deposit or similar
requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar Reserve
Percentage) against 

  

 20 

 
assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its Applicable
Lending Office) or on the London interbank market any other condition (other than in respect of Taxes or Other Taxes) affecting its Euro-Dollar Loans, its Note or its obligation to make Euro-Dollar Loans or its obligations hereunder in respect of
Letters of Credit and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan or of issuing or participating in any Letter of Credit, or to reduce the
amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed by such Bank to be material, then, within 15 days after demand by such Bank
(with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction; provided that no such amount shall be payable with respect to
any period commencing more than 90 days prior to the date such Bank first notifies the Borrower of its intention to demand compensation therefor under this Section 8.03(a). 
 (b) If any Bank shall have determined that, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency given or made after the date of this Agreement, has or would have the effect of
reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but for such adoption, change, request or
directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction; provided that no such amount shall be payable with respect to any period commencing less than 30 days after the
date such Bank first notifies the Borrower of its intention to demand compensation under this Section 8.03(b). 
 (c) Each Bank
will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable
Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this
Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. 

Section 8.04. Taxes. (a) For purposes of this Section 8.04, the following terms have the following meanings: 
 “Taxes” means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the
Borrower pursuant to this Agreement or any Note, and all liabilities with respect thereto, excluding (i) in the case of each Bank and the Administrative Agent, taxes imposed on its income, net worth or gross receipts and franchise or
similar taxes imposed on it by a jurisdiction under the laws of which such Bank or the Administrative Agent (as the case may be) is organized or in which its principal executive office is located or, in the case of each Bank, in which its Applicable
Lending Office is located and (ii) in the case of each Bank, any United States withholding tax imposed on such payments except to the extent that such Bank is subject to United States withholding tax by reason of a U.S. Tax Law Change.

 “Other Taxes” means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or
levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note. 
 “U.S. Tax Law Change” means with respect to any Bank or Participant the occurrence (x) in the case of each Bank listed on the signature pages
hereof, after the date of its execution and delivery of this Agreement and (y) in the case of any other Bank, after the date such Bank shall have become a Bank hereunder, and (z) in the case of each Participant, after the date such
Participant became a Participant hereunder, of the adoption of any applicable U.S. federal law, U.S. federal rule or U.S. federal regulation relating to taxation, or any change therein, or the entry into force, modification or revocation of any
income tax convention or treaty to which the United States is a party. 
 (b) Any and all payments by the Borrower to or for the account
of any Bank or the Administrative Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such
payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 8.04) such Bank or the Administrative Agent (as the
case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.01, the original or a certified copy of a receipt evidencing payment
thereof. 
  

 21 

 (c) The Borrower agrees to indemnify each Bank and the Administrative Agent for the full amount of
Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 8.04) paid by such Bank or the Administrative Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be paid within 15 days after such Bank or the Administrative Agent (as the case may be) makes demand therefor. 

(d) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter as required by law (but only so long as such Bank remains
lawfully able to do so), shall provide the Borrower two completed and duly executed copies of Internal Revenue Service form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the Internal Revenue Service, or other documentation
reasonably requested by the Borrower, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which exempts the Bank from United States withholding tax or reduces the rate of withholding tax
on payments of interest for the account of such Bank or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. 
 (e) For any period with respect to which a Bank has failed to provide the Borrower with the appropriate form pursuant to Section 8.04(d)
(unless such failure is due to a U.S. Tax Law Change), such Bank shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with respect to any Taxes or Other Taxes which would not have been payable had such form been so
provided; provided that if a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as
such Bank shall reasonably request to assist such Bank to recover such Taxes (it being understood, however, that the Borrower shall have no liability to such Bank in respect of such Taxes). 
 (f) If the Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 8.04, then such Bank will
take such action (including changing the jurisdiction of its Applicable Lending Office) as in the good faith judgment of such Bank (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not
otherwise disadvantageous to such Bank. 
 (g) If any Bank or the Administrative Agent receives a refund (including a refund in the form
of a credit against taxes that are otherwise payable by the Bank or the Administrative Agent) of any Taxes or Other Taxes for which the Borrower has made a payment under Section 8.04(b) or (c) and such refund was received from the taxing
authority which originally imposed such Taxes or Other Taxes, such Bank or the Administrative Agent agrees to reimburse the Borrower to the extent of such refund; provided that nothing contained in this paragraph (g) shall require any
Bank or the Administrative Agent to seek any such refund or make available its tax returns (or any other information relating to its taxes which it deems to be confidential). 
 Section 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make or to continue or convert
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) or 8.04 with respect to its Euro-Dollar Loans and the Borrower shall, by at
least five Euro-Dollar Business Days’ prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the
circumstances giving rise to such suspension or demand for compensation no longer apply: 
 (a) all Loans which would otherwise be made
by such Bank as (or continued as or converted to) Euro-Dollar Loans, as the case may be, shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and

 (b) after each of its Euro-Dollar Loans has been repaid, all payments of principal which would otherwise be applied to repay such
Loans shall be applied to repay its Base Rate Loans instead. 
 If such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Banks.

 Section 8.06. Substitution of Bank; Termination Option. If (i) the obligation of any Bank to make or to convert or continue
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Bank has demanded compensation under Section 8.03 or 8.04, (iii) any Bank exercises its right not to extend its Commitment
Termination Date pursuant to Section 2.01(c) or (iv) Investment Grade Status ceases to exist as to any Bank, then: 
 (a) the
Borrower shall have the right, with the assistance of the Administrative Agent, to designate a substitute bank or banks (which may be one or more of the Banks) mutually satisfactory to the Borrower, the Administrative Agent and the Issuing Banks
(whose consent shall not be unreasonably withheld or delayed) to purchase for cash, pursuant to an Assignment and Assumption 

  

 22 

 
Agreement in substantially the form of Exhibit D hereto, the outstanding Loans of such Bank and assume the Commitment and Letter of Credit Liabilities of such Bank,
without recourse to or warranty by, or expense to, such Bank, for a purchase price equal to the principal amount of all of such Bank’s outstanding Loans and funded Letter of Credit Liabilities plus any accrued but unpaid interest thereon and
the accrued but unpaid fees in respect of such Bank’s Commitment hereunder and all other amounts payable by the Borrower to such Bank hereunder plus such amount, if any, as would be payable pursuant to Section 2.13 if the outstanding Loans
of such Bank were prepaid in their entirety on the date of consummation of such assignment; and 
 (b) if at the time Investment Grade
Status exists as to the Borrower, the Borrower may elect to terminate this Agreement as to such Bank; provided that (i) the Borrower notifies such Bank through the Administrative Agent of such election at least three Euro-Dollar Business
Days before the effective date of such termination, (ii) the Borrower repays or prepays the principal amount of all outstanding Loans made by such Bank plus any accrued but unpaid interest thereon and the accrued but unpaid fees in respect of
such Bank’s Commitment hereunder plus all other amounts payable by the Borrower to such Bank hereunder, not later than the effective date of such termination and (iii) if at the effective date of such termination, any Letter of Credit
Liabilities are outstanding, the conditions specified in Section 3.02 would be satisfied (after giving effect to such termination) were the related Letters of Credit issued on such date. Upon satisfaction of the foregoing conditions, the
Commitment of such Bank shall terminate on the effective date specified in such notice, its participation in any outstanding Letters of Credit shall terminate on such effective date and the participations of the other Banks therein shall be
redetermined as of such date as if such Letters of Credit had been issued on such date.

agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind, including, without limitation, the reasonable
fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such Indemnitee shall be designated a party thereto) relating to or arising out
of this Agreement or any actual or proposed use of proceeds of Loans hereunder; provided that no Indemnitee shall have the right to be indemnified hereunder for such Indemnitee’s own gross negligence or willful misconduct as determined
by a court of competent jurisdiction. 
 Section 9.04. Sharing of Set-offs. Each Bank agrees that if it shall, by exercising any right of
set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount then due with respect to the Loans and Letter of Credit Liabilities held by it which is greater than the proportion received by any other Bank in respect
of the aggregate amount then due with respect to the Loans and Letter of Credit Liabilities held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Loans and Letter of Credit
Liabilities held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments with respect to the Loans and Letter of Credit Liabilities held by the Banks shall be shared by the Banks pro rata;
provided that nothing in this Section shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than
its indebtedness under this Agreement. 
  

 23 

 Section 9.05. Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or
waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Banks (and, if the rights or duties of any Agent or any Issuing Bank are affected thereby, by such Person); provided that no such
amendment or waiver shall (a) unless signed by each affected Bank, (i) increase the Commitment of any Bank or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or the amount to
be reimbursed in respect of any Letter of Credit or any interest thereon or any fees hereunder or (iii) postpone the date fixed for any payment of principal of or interest on any Loan or for reimbursement in respect of any Letter of Credit or
interest thereon or any fees hereunder or for termination of any Commitment or (b) unless signed by all Banks, (i) change the definition of Required Banks or the provisions of this Section 9.05 or (ii) change the provisions of
Section 9.04. 
 Section 9.06. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns and each Indemnitee, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all
Banks. 
 (b) Any Bank may, with the consent (unless an Event of Default then exists) of the Borrower (such consent not to be
unreasonably withheld or delayed), at any time grant to one or more banks or other institutions (each a “Participant”) participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities;
provided that any Bank may, without the consent of the Borrower, at any time grant participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities to another Bank, an Approved Fund or an Affiliate of such
transferor Bank. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Administrative Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and
the Borrower, the Issuing Banks and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Any agreement pursuant to which any Bank may
grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or
waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (i), (ii) or (iii) of
Section 9.05 without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article 8 with respect to its participating
interest, subject to the performance by such Participant of the obligations of a Bank thereunder. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement
only to the extent of a participating interest granted in accordance with this subsection (b). 
 (c) Any Bank may at any time assign to
one or more banks or other financial institutions (each an “Assignee”) all, or a proportionate part (equivalent to an initial Commitment of not less than $10,000,000 (unless the Borrower and the Administrative Agent shall otherwise
agree)) of all, of its rights and obligations under this Agreement and its Note (if any), and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto
executed by such Assignee and such transferor Bank, with (and only with and subject to) the prior written consent of the Issuing Banks, the Administrative Agent (which shall not be unreasonably withheld or delayed) and, so long as no Event of
Default has occurred and is continuing, the Borrower (which shall not be unreasonably withheld or delayed); provided that unless such assignment is of the entire right, title and interest of the transferor Bank hereunder, after making any
such assignment such transferor Bank shall have a Commitment of at least $10,000,000 (unless the Borrower and the Administrative Agent shall otherwise agree). Upon execution and delivery of such instrument of assumption and payment by such Assignee
to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment
as set forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any
assignment pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required by the Assignee, a Note is issued to the Assignee. If the Assignee is not
incorporated under the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account, deliver to the Borrower and the Administrative Agent certification as
to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 8.04. All assignments (other than assignments to Affiliates) shall be subject to a transaction fee established by, and payable by
the transferor Bank to, the Administrative Agent for its own account (which shall not exceed $5,000). 
 (d) Any Bank may at any time
assign all or any portion of its rights under this Agreement and its Note (if any) to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder or modify any such obligations. 
 (e) No Assignee, Participant or other transferee of any Bank’s rights (including any Applicable Lending Office other than such Bank’s
initial Applicable Lending Office) shall be entitled to receive any greater payment under Section 8.03 or 8.04 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made by reason of
the provisions 

  

 24 

 
of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the
circumstances giving rise to such greater payment did not exist. 
 Section 9.07. Collateral. Each of the Banks represents to the
Administrative Agent and each of the other Banks that it in good faith is not relying upon any “margin stock” (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

 Section 9.08. Confidentiality. Each Agent and each Bank agrees to keep any information delivered or made available by the Borrower
pursuant to this Agreement confidential from anyone other than persons employed or retained by such Bank and its affiliates who are engaged in evaluating, approving, structuring or administering the credit facility contemplated hereby;
provided that nothing herein shall prevent any Bank from disclosing such information (a) to any other Bank or any Agent, (b) to any other Person if reasonably incidental to the administration of the credit facility contemplated
hereby, (c) upon the order of any court or administrative agency, (d) upon the request or demand of any regulatory agency or authority, (e) which had been publicly disclosed other than as a result of a disclosure by any Agent or any
Bank prohibited by this Agreement, (f) in connection with any litigation to which any Agent, any Bank or its subsidiaries or Parent may be a party, (g) to the extent necessary in connection with the exercise of any remedy hereunder,
(h) to such Bank’s or any Agent’s legal counsel and independent auditors and (i) subject to provisions substantially similar to those contained in this Section 9.08, to any actual or proposed Participant or Assignee.

 Section 9.09. Governing Law; Submission to Jurisdiction. This Agreement and each Note (if any) shall be construed in accordance with and
governed by the law of the State of New York. The Borrower hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City for
purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. The Borrower irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. 
 Section 9.10. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written,
relating to the subject matter hereof. 
 Section 9.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENTS, THE ISSUING BANKS AND THE
BANKS, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 Section 9.12. USA Patriot Act. Each Bank hereby notifies the Borrower 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 the Borrower, which information includes the name and address of the Borrower and other
information that will allow such Bank to identify the Borrower in accordance with the Act.

 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective
authorized officers as of the day and year first above written.

 The Euro-Dollar Margin for any Term Loan shall equal the sum of (i) the rate that would otherwise be in
effect based upon the table above and (ii) 12.5 basis points. 
 *The “Utilization” applicable to any date is the percentage
equivalent of a fraction the numerator of which is the sum of (i) the aggregate outstanding principal amount of the Loans determined at such time after giving effect, if one or more Loans are being made at such time, to any substantially
concurrent application of the proceeds thereof to repay one or more other Loans plus (ii) the aggregate amount of the Letter of Credit Liabilities of all Banks at such time and the denominator of which is the aggregate amount of the Commitments
at such date. If for any reason any Loans or Letter of Credit Liabilities remain outstanding following termination of the Commitments, Utilization will be deemed to be 100%. 
 The credit ratings to be utilized for purposes of this Schedule are those indicated for or assigned to the senior unsecured long-term debt securities of the
Borrower without third-party credit enhancement, and any rating indicated for or assigned to any other debt security of the Borrower shall be disregarded. The ratings in effect for any day are those in effect at the close of business on such day. A
change in credit rating will result in an immediate change in the applicable pricing. In the case of split ratings from S&P and Moody’s, the rating to be used to determine the applicable pricing is a rating one notch higher than the lower
of the two.

 OPINION OF INTERNAL COUNSEL OF THE BORROWER 
  
 [Effective
Date] 
 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Citibank, N.A. 
 as Administrative Agent 
 388 Greenwich Street 
 New York, New
York 10013 
  
 Ladies and Gentlemen: 
 I am [title of internal counsel] of Duke Power Company LLC (the “Borrower”) and have acted as its counsel in connection with the Amended and
Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among the Borrower, the banks listed on the signature pages thereof, Citibank, N.A., as Administrative Agent, and Bank of America, N.A., as
Syndication Agent. Capitalized terms defined in the Credit Agreement are used herein as therein defined. This opinion letter is being delivered pursuant to Section 3.01(b) of the Credit Agreement. 
 In such capacity, I or attorneys under my direct supervision have examined originals or copies, certified or otherwise identified to my satisfaction, of such
documents, company records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or advisable for purposes of this opinion. 
 Upon the basis of the foregoing, I am of the opinion that: 
 1. The Borrower is limited liability company, validly existing and in good standing under the laws of North Carolina. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement and any Notes are within the Borrower’s limited liability company powers, have been duly authorized by all necessary limited liability company action,
require no action by or in respect of, or filing with, any governmental body, agency or official (except for the approval of the obtaining of credit pursuant to the Credit Agreement by the North Carolina Utilities Commission and The Public Service
Commission of South Carolina, which has been obtained) and do not contravene, or constitute a default under, any provision of applicable law or regulation or of the certificate of formation or limited liability company agreement of the Borrower or,
to my knowledge, of any agreement, judgment, injunction, order, decree or other instrument binding upon the Borrower or, to my knowledge, result in the creation or imposition of any Lien on any asset of the Borrower or any of its Material
Subsidiaries. 
 3. The Credit Agreement and any Notes executed and delivered as of the date hereof have been duly executed and
delivered by the Borrower. 
 4. Except as disclosed in the Borrower’s annual report on Form 10-K for the fiscal year ended
December 31, 2005 and its quarterly report on Form 10-Q for the period ended March 31, 2006, to my knowledge (but without independent investigation), there is no action, suit or proceeding pending or threatened against or affecting, the
Borrower or any of its Subsidiaries before any court or arbitrator or any governmental body, agency or official, which would be likely to be decided adversely to the Borrower or such Subsidiary and, as a result, to have a material adverse effect
upon the business, consolidated financial position or consolidated results of operations of the Borrower and its Consolidated Subsidiaries, considered as a whole, or which in any manner draws into question the validity of the Credit Agreement or any
Notes. 
 The phrase “to my knowledge”, as used in the foregoing opinion, refers to my actual knowledge without any independent investigation
as to any such matters. 
 I am a member of the Bar of the State of North Carolina and do not express any opinion herein concerning any law other than
the law of the State of North Carolina and the federal law of the United States of America. 
 This opinion is rendered to you in connection with the
above-referenced matter and may not be relied upon by you for any other purpose, or relied upon by, or furnished to, any other Person, firm or corporation without my prior written consent, except for Additional Banks and Assignees. My opinions
expressed herein are as of the date hereof, and I undertake no obligation to advise you of any changes of applicable law or any other matters that may come to my attention after the date hereof that may affect my opinions expressed herein.

  
 Very truly yours, 

 EXHIBIT B-2 
  
 OPINION OF 
 ROBINSON, BRADSHAW & HINSON, P.A.,

 SPECIAL COUNSEL FOR THE BORROWER 
  
 [Effective Date] 
 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Citibank, N.A. 
 as Administrative Agent 
 388 Greenwich Street 
 New York, New York 10013 
  
 Ladies and Gentlemen: 
 We have acted as counsel to Duke Power Company LLC, a North Carolina limited liability company (the
“Borrower”), in connection with the Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among Duke Power Company LLC, the banks listed on the signature pages thereof,
Citibank, N.A., as Administrative Agent, and Bank of America, N.A., as Syndication Agent. Capitalized terms used herein and not defined shall have the meanings given to them in the Credit Agreement. This opinion letter is being delivered pursuant to
Section 3.01(b) of the Credit Agreement. 
 In connection with this opinion, we also examined originals, or copies identified to our satisfaction,
of such other documents and considered such matters of law and fact as we, in our professional judgment, have deemed appropriate to render the opinions contained herein. Where we have considered it appropriate, as to certain facts we have relied,
without investigation or analysis of any underlying data contained therein, upon certificates or other comparable documents of public officials and officers or other appropriate representatives of the Borrower. 
 In rendering the opinions contained herein, we have assumed, among other things, that the Credit Agreement and any Notes to be executed (i) are within the
Borrower’s limited liability company powers, (ii) have been duly authorized by all necessary limited liability company action, (iii) have been duly executed and delivered, (iv) require no action by or in respect of, or filing
with, any governmental body, agency of official, and (v) do not contravene, or constitute a default under, any provision of applicable law or regulation or of the Borrower’s certificate of formation or limited liability company agreement
or any agreement, judgment, injunction, order, decree or other instrument binding upon the Borrower or result in the creation or imposition of any Lien on any asset of the Borrower. In addition, we have assumed that the Credit Agreement fully states
the agreement between the Borrower and the Banks with respect to the matters addressed therein, and that the Credit Agreement constitutes a legal, valid and binding obligation of each Bank, enforceable in accordance with its respective terms.

 The opinions set forth herein are limited to matters governed by the laws of the State of North Carolina and the federal laws of the United States,
and no opinion is expressed herein as to the laws of any other jurisdiction. For purposes of our opinions, we have disregarded the choice of law provisions in the Credit Agreement and, instead, have assumed with your permission that the Credit
Agreement and the Notes are governed exclusively by the internal, substantive laws and judicial interpretations of the State of North Carolina. We express no opinion concerning any matter respecting or affected by any laws other than laws that a
lawyer in North Carolina exercising customary professional diligence would reasonably recognize as being directly applicable to the Borrower, the Loans, or any of them. 
 Based upon and subject to the foregoing and the further limitations and qualifications hereinafter expressed, it is our opinion that the Credit Agreement constitutes the legal, valid and binding obligation of the Borrower and
the Notes, if and when issued, will constitute legal, valid and binding obligations of the Borrower, in each case, enforceable against the Borrower in accordance with its terms. 
 The opinions expressed above are subject to the following qualifications and limitations: 
 1. Enforcement of the Credit Agreement and the Notes is subject to the effect of applicable bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium and similar laws affecting the enforcement of creditors’ rights generally. 
 2. Enforcement of the Credit
Agreement and the Notes is subject to the effect of general principles of equity (regardless of whether considered in a proceeding in equity or at law) by which a court with proper jurisdiction may deny rights of specific performance, injunction,
self-help, possessory remedies or other remedies. 
 3. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement or any Note that (i) purport to excuse a party for liability for its own acts, (ii) purport to make void any act done in contravention thereof, (iii) purport to authorize a party to act in its sole
discretion, (iv) require waivers or amendments to be made only in writing, (v) purport to effect waivers of constitutional, statutory or equitable rights or the effect of applicable laws, (vi) impose liquidated damages, penalties or
forfeiture, or (vii) purport to indemnify a party for its own negligence or willful misconduct. Indemnification provisions in the Credit Agreement are subject to and may be rendered unenforceable by applicable law or public policy, including
applicable securities law. 

 4. We do not express any opinion as to the enforceability of any provisions contained in the Credit
Agreement or the Notes purporting to require a party thereto to pay or reimburse attorneys’ fees incurred by another party, or to indemnify another party therefor, which may be limited by applicable statutes and decisions relating to the
collection and award of attorneys’ fees, including but not limited to North Carolina General Statutes § 6-21.2. 
 5. We
do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement purporting to waive the right of jury trial. Under North Carolina General Statutes § 22B-10, a provision for the waiver of the right to
a jury trial is unconscionable and unenforceable. 
 6. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement concerning choice of forum or consent to the jurisdiction of courts, venue of actions or means of service of process. 
 7. It is likely that North Carolina courts will enforce the provisions of the Credit Agreement providing for interest at a higher rate resulting from a Default or Event of Default (a ”Default Rate”) which
rate is higher than the rate otherwise stipulated in the Credit Agreement. The law, however, disfavors penalties, and it is possible that interest at the Default Rate may be held to be an unenforceable penalty, to the extent such rate exceeds the
rate applicable prior to a default under the Credit Agreement. Also, since North Carolina General Statutes § 24-10.1 expressly provides for late charges, it is possible that North Carolina courts, when faced specifically with the issue,
might rule that this statutory late charge preempts any other charge (such as default interest) by a bank for delinquent payments. The only North Carolina case which we have found that addresses this issue is a 1978 Court of Appeals decision, which
in our opinion is of limited precedential value, North Carolina National Bank v. Burnette, 38 N.C. App. 120, 247 S.E.2d 648 (1978), rev’d on other grounds, 297 N.C. 524, 256 S.E.2d 388 (1979). While the court in that case did
allow interest after default (commencing with the date requested in the complaint) at a rate six percent in excess of pre-default interest, we are unable to determine from the opinion that any question was raised as to this being penal in nature,
nor does the court address the possible question of the statutory late charge preempting a default interest surcharge. Therefore, since the North Carolina Supreme Court has not ruled in a properly presented case raising issues of its possible penal
nature and those of North Carolina General Statutes § 24-10.1, we are unwilling to express an unqualified opinion that the Default Rate of interest prescribed in the Credit Agreement is enforceable. 
 8. We do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement relating to evidentiary standards or
other standards by which the Credit Agreement are to be construed. 
 This opinion letter is delivered solely for your benefit in connection with the
Credit Agreement and, except for any Additional Bank or any Assignee which becomes a Bank pursuant to Section 2.17 or 9.06(c) of the Credit Agreement, may not be used or relied upon by any other Person or for any other purpose without our prior
written consent in each instance. Our opinions expressed herein are as of the date hereof, and we undertake no obligation to advise you of any changes of applicable law or any other matters that may come to our attention after the date hereof that
may affect our opinions expressed herein. 
  
 Very truly
yours,

 DAVIS POLK & WARDWELL, SPECIAL
COUNSEL 
 FOR THE AGENTS
  
 [Effective Date] 
 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Citibank, N.A., 
 as Administrative Agent 
 388 Greenwich Street 
 New York, New York 10013 
  
 Dear Sirs: 
 We have participated in the preparation of the Amended and Restated Credit Agreement (the “Credit Agreement”)
dated as of June 29, 2006 among Duke Power Company LLC, a North Carolina limited liability company (the “Borrower”), the banks listed on the signature pages thereof (the “Banks”), Citibank, N.A., as
Administrative Agent (the “Administrative Agent”), and Bank of America, N.A., as Syndication Agent, and have acted as special counsel for the Agents for the purpose of rendering this opinion pursuant to Section 3.01(c) of the
Credit Agreement. Terms defined in the Credit Agreement are used herein as therein defined. 
 We have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents, company records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes
of this opinion. 
 Upon the basis of the foregoing, we are of the opinion that: 
 1. The execution, delivery and performance by the Borrower of the Credit Agreement and the Notes are within the Borrower’s limited liability
company powers and have been duly authorized by all necessary limited liability company action. 
 2. The Credit Agreement constitutes a
valid and binding agreement of the Borrower and the Notes, if and when issued, constitute valid and binding obligations of the Borrower enforceable in accordance with their respective terms, except as the same may be limited by bankruptcy,
insolvency or similar laws affecting creditors’ rights generally and by general principles of equity. 
 In giving the foregoing opinion,
(i) we express no opinion as to the effect (if any) of any law of any jurisdiction (except the State of New York) in which any Bank is located which limits the rate of interest that such Bank may charge or collect and (ii) we have relied,
without independent investigation, as to all matters governed by the laws of North Carolina, upon the opinion of internal counsel of the Borrower, dated [Effective Date], a copy of which has been delivered to you. 
 This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or
furnished to any other person, firm or corporation without our prior written consent, except for Additional Banks and all Participants. 
  
 Very truly yours,

 ASSIGNMENT AND ASSUMPTION AGREEMENT 
  
 AGREEMENT dated as of             , 20     among [ASSIGNOR] (the
“Assignor”), [ASSIGNEE] (the “Assignee”), [DUKE POWER COMPANY LLC,] and CITIBANK, N.A., as Administrative Agent (the “Administrative Agent”). 
  
 W I T N E S S E T H 
 WHEREAS, this Assignment and Assumption Agreement (the “Agreement”) relates to the Amended and Restated Credit Agreement dated as of June 29,
2006 among Duke Power Company LLC (the “Borrower”), the Assignor and the other Banks party thereto, as Banks, the Administrative Agent and Bank of America, N.A., as Syndication Agent (the “Credit Agreement”);

 WHEREAS, as provided under the Credit Agreement, the Assignor has a Commitment to make Loans to the Borrower and participate in Letters of Credit in
an aggregate principal amount at any time outstanding not to exceed $            ;1 
 WHEREAS, Loans made to the Borrower by the Assignor under the Credit Agreement in the aggregate principal amount of $            are outstanding at the date hereof; 
 WHEREAS, Letters of Credit with a total amount available for drawing thereunder of $            are
outstanding at the date hereof; and 
 WHEREAS, the Assignor proposes to assign to the Assignee all of the rights of the Assignor under the Credit
Agreement in respect of a portion of its Commitment thereunder in an amount equal to $            (the “Assigned Amount”), together with a corresponding portion of its
outstanding Loans and Letter of Credit Liabilities, and the Assignee proposes to accept assignment of such rights and assume the corresponding obligations from the Assignor on such terms;* 
 NOW, THEREFORE, in consideration of the foregoing and the mutual agreements contained herein, the parties hereto agree as follows: 
 SECTION 1. Definitions. All capitalized terms not otherwise defined herein shall have the respective meanings set forth in the Credit
Agreement. 
 SECTION 2. Assignment. The Assignor hereby assigns and sells to the Assignee all of the rights of the Assignor
under the Credit Agreement to the extent of the Assigned Amount, and the Assignee hereby accepts such assignment from the Assignor and assumes all of the obligations of the Assignor under the Credit Agreement to the extent of the Assigned Amount,
including the purchase from the Assignor of the corresponding portion of the principal amount of the Loans made by, and Letter of Credit Liabilities of, the Assignor outstanding at the date hereof. Upon the execution and delivery hereof by the
Assignor, the Assignee [, the Borrower] [, the Issuing Banks] and the Administrative Agent, the payment of the amounts specified in Section 3 required to be paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed to
the rights and be obligated to perform the obligations of a Bank under the Credit Agreement with a Commitment in an amount equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by a like
amount and the Assignor released from its obligations under the Credit Agreement to the extent such obligations have been assumed by the Assignee. The assignment provided for herein shall be without recourse to the Assignor. 
 SECTION 3. Payments. As consideration for the assignment and sale contemplated in Section 2 hereof, the Assignee shall pay to the
Assignor on the date hereof in Federal funds the amount heretofore agreed between them.2 It is understood that facility [and Letter of Credit] fees accrued to the date hereof in respect of the Assigned Amount are for the
account of the Assignor and such fees accruing from and including the date hereof are for the account of the Assignee. Each of the Assignor and the Assignee hereby agrees that if it receives any amount under the Credit Agreement which is for the
account of the other party hereto, it shall receive the same for the account of such other party to the extent of such other party’s interest therein and shall promptly pay the same to such other party. 
 SECTION 4. Consent to Assignment. This Agreement is conditioned upon the consent of [the Borrower,] [the Issuing Banks] and the
Administrative Agent pursuant to Section 9.06(c) of the Credit Agreement. The execution of this Agreement by [the Borrower,] [the Issuing Banks] and the Administrative Agent is evidence of this consent. Pursuant to Section 9.06(c) the
Borrower agrees to execute and deliver a Note, if required by the Assignee, payable to the order of the Assignee to evidence the assignment and assumption provided for herein. 
 SECTION 5. Non-reliance on Assignor. The Assignor makes no representation or warranty in connection with, and shall have no
responsibility with respect to, the solvency, financial condition, or statements of any Borrower, or the validity and enforceability of the obligations of any Borrower in respect of the Credit Agreement or any Note. The Assignee acknowledges that it
has, independently and without reliance on the Assignor, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and will continue to be responsible for making
its own independent appraisal of the business, affairs and financial condition of the Borrower. 
  

	1	The asterisked provisions shall be appropriately revised in the event of an assignment after the Commitment Termination Date. 

	2	Amount should combine principal together with accrued interest and breakage compensation, if any, to be paid by the Assignee. It may be preferable in an appropriate case to specify these
amounts generically or by formula rather than as a fixed sum. 

 SECTION 6. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York. 
 SECTION 7. Counterparts. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 
 SECTION 8. Administrative Questionnaire. Attached is an Administrative Questionnaire duly completed by the Assignee.

 IN WITNESS WHEREOF, the parties have caused this Agreement to be executed and delivered by their duly authorized
officers as of the date first above written.
