 For purposes of the foregoing, (a) if only one Rating Agency provides a rating for Index Debt, the Tier
corresponding to that rating shall apply, unless such rating is by Fitch, in which case the Tier shall be deemed to be Tier 5, (b) if only two Rating Agencies provide a rating for Index Debt, then (i) if both ratings correspond to the same
Tier, that Tier shall apply, (ii) if there is a one Tier difference between the two ratings, then the Tier corresponding to the higher rating shall be used (with the rating for Tier 1 being the highest and the rating for Tier 5 being the
lowest), and (iii) if there is a greater than one Tier difference between the ratings, then the Tier that is one Tier below the higher rating will be used, (c) if three Rating Agencies provide a rating for Index Debt, then (i) if all
three ratings correspond to the same Tier, that Tier shall apply, (ii) if all three ratings are at different Tiers, the Tier that applies to the middle of the three ratings shall apply, and (iii) if two ratings correspond to the same Tier

in the rating system of such Rating Agency), such change shall be effective as of the date on which it is first announced or published by the applicable Rating Agency or, in the absence of such announcement or publication, on the effective date of
such rating. 
 Each change in the Applicable Margin shall apply during the period commencing on the effective date of such change and
ending on the date immediately preceding the effective date of the next such change. If the rating system of any Rating Agency shall change, or if any Rating Agency shall cease to be in the business of rating corporate debt obligations, the Borrower
and the Lenders shall negotiate in good faith to amend these provisions to reflect such changed rating system or the unavailability of ratings from such Rating Agency and, pending the effectiveness of any such amendment, the Applicable Margin shall
be determined by reference to the rating most recently in effect prior to such change or cessation; provided that, if the rating system of both Moody’s and S&P shall change, or if both Moody’s and S&P shall cease to be in
the business of rating corporate debt obligations, pending the effectiveness of any such amendment, the Tier shall be deemed to be Tier 5. From the Amendment No. 1 Effective Date until the first such ratings change, if any, the Applicable
Margin shall be determined by reference to Tier 3.

 Notwithstanding the foregoing, until the date that is three (3) Business Days after the
date of the Borrower’s delivery of irrevocable written notice to the Administrative Agent stating that the Borrower wishes to include Fitch as a Rating Agency for purposes of determining the Applicable Margin, Fitch shall be deemed not to
provide an Index Debt rating for purposes of determining the Applicable Margin.

Section 1.7 Restricted Lenders. With respect to each Restricted Lender, Sections 4.9, 4.18, 5.1, 5.9, and 6.9 shall only benefit
such Restricted Lender to the extent that such provision would not result in any violation of, conflict with or liability under (a) the Council Regulation (EC) No. 2271/96 of 22 November 1996, as amended from time to time, or any law
or regulation implementing such Council Regulation in any member state of the European Union or the United Kingdom, (b) section 7 of the German Foreign Trade Ordinance (Aubenwirtschaftsverordnung

that on or prior to the date of such amendment, waiver, determination or direction (and until such time as such Lender shall advise the Administrative Agent in writing otherwise), such Lender has advised the Administrative Agent in writing that it
does not have such benefit, the Commitments of that Restricted Lender will be excluded for the purpose of determining whether the consent of the Majority Lenders has been obtained or whether the determination or direction by the Majority Lenders has
been made. The foregoing limitations are strictly limited to the Restricted Lenders and nothing contained in this paragraph shall affect the applicability or benefit of Sections 4.9, 4.18, 5.1, 5.9, and 6.9 to any other Lender or party hereto. For
purposes of this Section 1.7, a “Restricted Lender” means any Lender to whom the Council Regulation (or law or regulation implementing the Council Regulation), section 7 of the German Foreign Trade Ordinance, or any similar
anti-boycott statute in any member state of the European Union or the United Kingdom applies. 
 Section 1.8 Rates. The
Administrative Agent does not warrant or accept responsibility for, and shall not have any liability with respect to, the administration, submission or any other matter related to the rates in the definition of “Eurocurrency Adjusted Base
Rate,” “Eurocurrency Rate,” or with respect to any rate that is an alternative or replacement for or successor to any such rate (including, without limitation, any Benchmark Replacement) or the effect of any of the foregoing, or of
any Benchmark Replacement Conforming Changes.

connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or
liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the
first date of its existence by the holders of its equity interests at such time. 
 ARTICLE II 

THE ADVANCES AND THE LETTERS OF CREDIT 

Section 2.1 The Advances. 

(a) Revolving Advances. Each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Revolving
Advances to the Borrower from time to time on any Business Day prior to the latest Maturity Date in an aggregate amount not to exceed at any time outstanding an amount equal to such Lender’s Revolving Commitment less the sum of the Dollar
Amount of (i) the aggregate principal amount of Revolving Advances owing to such Lender at such time, (ii) such Lender’s Pro Rata Share of the aggregate of the Letter of Credit Exposure at such time, and (iii) such Lender’s
Pro Rata Share of the Swingline Advances; provided that, (A) before and after giving effect to such Borrowing, the aggregate Dollar Amount of all outstanding Revolving Advances, Swingline Advances and Letter of Credit Exposure at any
time may not exceed the aggregate Revolving Commitments at such time, (B) such Revolving Advances may be denominated and funded in any Agreed Currency and (C) before and after giving effect to such Borrowing, the aggregate Dollar Amount of
all outstanding Revolving Advances, Swingline Advances and Letter of Credit Exposure which are denominated in Norwegian Kroner may not exceed $500,000,000 at any time. Within the limits of each Lender’s Revolving Commitment, the Borrower may
from time to time prepay pursuant to Section 2.7 and reborrow under this Section 2.1(a). 
 (b) Swingline Advances. 

(i) On the terms and conditions set forth in this Agreement, (A) the US Swingline Lender agrees to, from time-to-time on any Business Day during the period from the date of this Agreement until the US Swingline Lender’s Maturity Date, make advances (“US Swingline
Advances”) to the Borrower in an aggregate principal amount not to exceed $200,000,000 outstanding at any time and denominated in US Dollars; (B) the Canadian Swingline Lender agrees to, from time-to-time on any Business Day during the period from the date of this Agreement until the Canadian Swingline Lender’s Maturity Date, make advances (“Canadian Swingline Advances”) to
the Borrower in an aggregate principal amount not to exceed $100,000,000 outstanding at any time and denominated in Canadian Dollars or US Dollars; (C) the Norwegian Swingline Lender agrees to, from time-to-time on any Business Day during the period from the date of this Agreement until the Norwegian Swingline Lender’s Maturity Date, make advances (“Norwegian Swingline Advances”) to
the Borrower in an aggregate principal amount not to exceed $100,000,000 outstanding at any time and denominated in Norwegian Kroner or US Dollars; provided that, before and after giving effect to such Borrowing, the aggregate Dollar Amount of all
outstanding Revolving Advances, Swingline Advances and Letter of Credit Exposure which are denominated in Norwegian Kroner may not exceed $500,000,000 at any time; and (D) the UK Swingline Lender agrees to, from
time-to-time on any Business Day during the period from the date of this Agreement until the UK Swingline Lender’s Maturity Date, make advances (“UK
Swingline Advances”) to the Borrower in an aggregate principal amount not to exceed $100,000,000 outstanding at any time and denominated in Pounds Sterling or US Dollars; 

  
 28 












 provided that, (x) with respect to all Swingline Subfacilities, before and after
giving effect to any such Borrowing, the aggregate Dollar Amount of the sum of all outstanding Revolving Advances, Swingline Advances and the Letter of Credit Exposure may not exceed the aggregate Revolving Commitments at such time; (y) with
respect to all Swingline Subfacilities, no Swingline Advance shall be made if the statements set forth in Section 3.2 are not true on the date of the making of such Swingline Advance, it being agreed by the Borrower that the giving of the
applicable Notice of Borrowing and the acceptance by the Borrower of the proceeds of such Swingline Advance shall constitute a representation and warranty by the Borrower that on the date of such Swingline Advance such statements are true; and
(z) with respect to any Foreign Swingline Advance, whether denominated in US Dollars or any Foreign Currency, such Foreign Swingline Advance shall be in a minimum amount of $500,000. Subject to the other provisions hereof, the Borrower may from
time-to-time borrow, prepay (in whole or in part) and reborrow Swingline Advances. Immediately upon the making of a Swingline Advance, each Lender shall be deemed to,
and hereby irrevocably and unconditionally agrees to, purchase from the applicable Swingline Lender a risk participation in such Swingline Advance in an amount equal to its Pro Rata Share of such Swingline Advance. 

(ii) Except as provided in the following clause (iv) below, each request for a US Swingline Advance shall be made pursuant
to telephone notice to the US Swingline Lender given no later than 1:00 p.m. (Houston, Texas time) on the date of the proposed Swingline Advance, promptly confirmed by a completed and executed Notice of Borrowing faxed to the Administrative Agent.
The US Swingline Lender will promptly (but in any event prior to 3:00 p.m. (Houston, Texas time)) on the date of such proposed US Swingline Advance make such US Swingline Advance available to the Borrower at the Borrower’s account with the
Administrative Agent or such other accounts as may be designated by the Borrower. 
 (iii) Except as provided in the
following clause (iv) below, each request for a Foreign Swingline Advance shall be made pursuant to telephone notice to the applicable Foreign Swingline Lender, together with a written notice to the Administrative Agent, given no later than
10:00 a.m. in the Applicable Time specified by the applicable Foreign Swingline Lender, promptly confirmed by a completed and executed Notice of Borrowing faxed to the applicable Foreign Swingline Lender and the Administrative Agent. If, on the date
such request is made, the Dollar Amount of the sum of the outstanding Revolving Advances and the Letter of Credit Exposure is equal to or less than 50% of the aggregate Revolving Commitments, then subject to the terms and conditions hereof, the
applicable Foreign Swingline Lender will, not later than 2:00 p.m. (in the Applicable Time) on the borrowing date specified for such Swingline Advance, make the amount of such Swingline Advance available at the Borrower’s account with the
Administrative Agent or such other accounts as may be designated by the Borrower. However, if on the date such request is made, the Dollar Amount of the sum of the outstanding Revolving Advances and the Letter of Credit Exposure is greater than 50%
of the aggregate Revolving Commitments, then (A) promptly after receipt by the applicable Foreign Swingline Lender of any request for a Foreign Swingline Advance, the applicable Foreign Swingline Lender will confirm with the Administrative
Agent that the Administrative Agent has also received such request and, if not, the applicable Foreign Swingline Lender will notify the Administrative Agent of the contents thereof, and (B) unless the applicable Foreign Swingline Lender has
received notice in writing from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. (in the Applicable Time) on the date of the proposed Swingline Advance directing the applicable 

  
 29 












 
Foreign Swingline Lender not to make such Swingline Advance as a result of the limitations set forth in the first proviso of Section 2.1(b) above then, subject to the terms and conditions
hereof, the applicable foreign Swingline Lender will, not later than 3:00 p.m. (in the Applicable Time) on the borrowing date specified for such Swingline Advance, make the amount of such Swingline Advance available at the Borrower’s account
with the Administrative Agent or such other accounts as may be designated by the Borrower. 
 (iv) With respect to Swingline
Advances denominated in Dollars, each Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender
make an Adjusted Base Rate Advance in an amount equal to such Lender’s Pro Rata Share of such Swingline Advances in order to refinance such Swingline Advances. With respect to Foreign Swingline Advances, each Swingline Lender in its sole and
absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender make a Eurocurrency Rate Advance in the same Foreign Currency, in an amount equal to
such Lender’s Pro Rata Share of such Swingline Advances and with Interest Period of one month. The applicable Swingline Lender shall give the Administrative Agent notice of such Mandatory Revolving Borrowing (A) by 12:00 p.m. (Houston,
Texas time) on the date before the proposed Mandatory Revolving Borrowing is to be made in the case of an Adjusted Base Rate Advance and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed
Mandatory Revolving Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency, which notice the Administrative Agent will promptly forward to each Lender. Each Lender shall make its Revolving Advance available to the
Administrative Agent for the account of the applicable Swingline Lender in immediately available funds by 2:00 p.m. (Houston, Texas time) on the date requested, and the Borrower hereby irrevocably instructs the applicable Swingline Lender to apply
the proceeds of such Mandatory Revolving Borrowing to the payment of the outstanding Swingline Advances. 
 (v) If for any
reason any Swingline Advance cannot be refinanced by a Revolving Borrowing in accordance with clause (iv) above, the request for the Revolving Advances submitted by the applicable Swingline Lender as set forth therein shall be deemed to be a
request by such Swingline Lender that each of the Lenders fund its risk participation in the relevant Swingline Advances and each Lender’s payment to the Administrative Agent for the account of the applicable Swingline Lender pursuant to clause
(iv) above shall be deemed payment in respect of such participation. 
 (vi) If any Lender fails to make available to
the Administrative Agent for the account of the applicable Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.1(b) by the time specified in this Section 2.1(b), such
Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is
immediately available to such Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect. A certificate of such Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to
any amounts owing under this clause (vi) shall be conclusive absent manifest error. 

  
 30 












 (vii) Each Lender’s obligation to make the Revolving Advances or to
purchase and fund risk participations in Swingline Advances pursuant to this Section 2.1(b) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or
other right which such Lender may have against any Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, (C) whether or not the conditions precedent in
Section 3.2 have been satisfied, (D) termination of the Revolving Commitments or acceleration of the Advances, and (E) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk
participations shall relieve or otherwise impair the obligation of the Borrower to repay Swingline Advances, together with interest as provided herein. 

(viii) At any time after any Lender has purchased and funded a risk participation in a Swingline Advance, if the applicable
Swingline Lender receives any payment on account of such Swingline Advance, such Swingline Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of
time during which such Lender’s risk participation was funded) in the same funds as those received by such Swingline Lender. 

(ix) Each Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Advances made by such
Swingline Lender. Until a Lender funds its Adjusted Base Rate Advance, Eurocurrency Rate Advance or risk participation pursuant to this Section 2.1(b) to refinance such Lender’s Pro Rata Share of any Swingline Advance, interest in respect
of such Pro Rata Share shall be solely for the account of the applicable Swingline Lender. 
 (x) The Borrower shall make
all payments of principal and interest in respect of any Swingline Advances directly to the applicable Swingline Lender. 

(xi) For purposes of calculating outstandings under this Agreement (a) on each March 31, June 30,
September 30 and December 31, commencing June 30, 2017, and (b) from time to time as the Administrative Agent may request, each Swingline Lender shall provide the Administrative Agent with a daily log, in form and detail
reasonably acceptable to the Administrative Agent, setting forth the outstanding Dollar Amount of the Swingline Advances made by such Swingline Lender using the Exchange Rate as most recently determined by the Administrative Agent. 

Section 2.2 Method of Borrowing. 

(a) Notice. Each Revolving Borrowing shall be made pursuant to a Notice of Borrowing and given: 

(i) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the fourth Business Day
before the date of the proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency, 

(ii) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the third Business Day

(iii) by the Borrower to the Administrative Agent not later than 10:00 a.m. (Houston, Texas time) on the date of the
proposed Borrowing in the case of an Adjusted Base Rate Advance. 

  
 31 












 The Administrative Agent shall give each Lender prompt notice on the day of receipt of timely Notice of
Borrowing of such proposed Borrowing by facsimile. Each Notice of Borrowing shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing (which confirmation may be provided by facsimile or with a “PDF” file
delivered in an e-mail with a return acknowledgment requested), specifying the (i) requested date of such Borrowing (which shall be a Business Day), (ii) requested Type of Advances comprising such
Borrowing, (iii) aggregate amount of such Borrowing, (iv) if such Borrowing is to be comprised of Eurocurrency Rate Advances, the Interest Period for each such Advance, and (v) the Designated Currency of such Borrowing. In the case of
a proposed Borrowing comprised of Eurocurrency Rate Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.6(b). Each Lender shall, before 3:00 p.m. (Houston, Texas time) on the date
of the proposed Borrowing, make available for the account of its Lending Office to the Administrative Agent at its address referred to in Section 9.2, or such other location as the Administrative Agent may specify by notice to the Lenders, in
same day funds, such Lender’s Pro Rata Share of such Borrowing. Promptly upon the Administrative Agent’s receipt of such funds (but in any event not later than 4:00 p.m. (Houston, Texas time) on the date of the proposed Borrowing)
and provided that the applicable conditions set forth in Article III have been satisfied, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent. 

(b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing
under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office (i) no later than 10:00 a.m. (Houston, Texas time) on the proposed
Conversion date in the case of a Conversion of such Advances to Adjusted Base Rate Advances, (ii) no later than 12:00 p.m. (Houston, Texas time) at least three Business Days in advance of the proposed Conversion or continuation date in the case
of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Dollars; and (iii) no later than 12:00 p.m. (Houston, Texas time) at least four Business Days in advance of the proposed Conversion or continuation date in the
case of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Foreign Currencies. Each such Notice of Conversion or Continuation shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing (which
confirmation may be provided by facsimile or with a “PDF” file delivered in an e-mail with a return acknowledgment requested), specifying (A) the requested Conversion or continuation date (which
shall be a Business Day), (B) the Borrowing amount and Type of the Advances to be Converted or continued, (C) whether a Conversion or continuation is requested, and if a Conversion, into what Type of Advances, and (D) in the case of a
Conversion to, or a continuation of, Eurocurrency Rate Advances, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each Lender with a copy
thereof and, in the case of a Conversion to or a continuation of Eurocurrency Rate Advances, notify each Lender of the applicable interest rate under Section 2.6(b). For purposes other than the conditions set forth in Section 3.2, the
portion of Revolving Advances comprising part of the same Revolving Borrowing that are Converted to Revolving Advances of another Type shall constitute a new Revolving Borrowing. 

(c) Certain Limitations. Notwithstanding anything herein to the contrary: 

(i) each Borrowing (other than a Borrowing of Swingline Advances) shall (A) in the case of Eurocurrency Rate
Advances, be in an aggregate amount not less than $3,000,000 and greater multiples of $1,000,000 in excess thereof, (B) in the case of Adjusted Base Rate Advances, be in an aggregate amount not less than $500,000 and greater multiples of
$100,000 in excess thereof, and (C) consist of Advances of the same Type made on the same day by the Lenders according to their Pro Rata Share; 

(ii) at no time shall there be more than eight Interest Periods applicable to outstanding Eurocurrency Rate Advances; 


  
 32 












 (iii) no single Borrowing consisting of Eurocurrency Rate Advances may
include Advances in different currencies; 
 (iv) the Borrower may not select Eurocurrency Rate Advances for any
Borrowing to be made, Converted or continued if (A) the aggregate Dollar Amount of such Borrowing is less than $3,000,000 or (B) a Default or Event of Default has occurred and is continuing; 

(v) (A) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurocurrency Rate
Advances, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such
Lender or its Lending Office to perform its obligations under this Agreement to make Eurocurrency Rate Advances or to fund or maintain Eurocurrency Rate Advances, or any Governmental Authority has imposed material restrictions on the authority of
such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then (1) if the requested Borrowing was of Revolving Advances denominated in Dollars, such Lender’s Pro Rata Share of
such Borrowing shall be made as an Adjusted Base Rate Advance of such Lender, (2) in any event, such Adjusted Base Rate Advance shall be considered part of the same Borrowing and interest on such Adjusted Base Rate Advance shall be due and
payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable, and (3) any obligation of such Lender to make, continue, or Convert to, Eurocurrency Rate Advances in
the affected currency or currencies, including in connection with such requested Borrowing, shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer
exist; and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the
effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender; 

(vi) subject to Section 2.6(f), if the Administrative Agent is unable to determine the Eurocurrency Rate for
Eurocurrency Rate Advances comprising any requested Revolving Borrowing, the right of the Borrower to select Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Borrowing shall be suspended
until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and upon receipt by the Borrower of the notice of such suspension, the Borrower may revoke the pending request
or, failing that, each Revolving Advance comprising such Borrowing shall be made as an Adjusted Base Rate Advance in the Dollar Amount of the originally requested Advance; 

(vii) subject to Section 2.6(f), if the Majority Lenders shall, at least one Business Day before the date of any
requested Borrowing, notify the Administrative Agent that (A) the Eurocurrency Rate for Eurocurrency Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurocurrency
Rate Advances, or (B) deposits are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurocurrency Rate Advance, the right of the Borrower to select
Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Revolving Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing
such suspension no longer exist, and upon receipt by the Borrower of the 
 notice of such suspension, the Borrower may revoke the pending
request or, failing that, each Advance comprising such Borrowing shall be made as an Adjusted Base Rate Advance in the Dollar Amount of the originally requested Advance; 

  
 33 












 (viii) if any Lender shall, at any time prior to the making of any
requested Borrowing comprised of Eurocurrency Rate Advances denominated in a Foreign Currency, notify the Administrative Agent that, as a result of internal banking policy limitations on fundings in such Foreign Currency, such Lender cannot fund all
or any portion of its Pro Rata Share of such Borrowing, then (A) such portion shall be made as an Adjusted Base Rate Advance of such Lender, and (B) in any event, such Adjusted Base Rate Advance shall be considered part of the same
Borrowing and interest on such Adjusted Base Rate Advance shall be due and payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable; 

(ix) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurocurrency Rate
Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1 and paragraph (a) or (b) above, the Administrative Agent will forthwith so notify the Borrower and the Lenders and
(A) if denominated in Dollars, such affected Advances will be made available to the Borrower on the date of such Borrowing as Adjusted Base Rate Advances or, if such affected Advances are existing Advances, will be Converted into Adjusted Base
Rate Advances at the end of the Interest Period then in effect, and (B) if denominated in a Foreign Currency, the Borrower shall be deemed to have specified an Interest Period of one month for such affected Advances or, if such affected
Advances are existing Advances, such affected Advances will be continued as a Eurocurrency Rate Advance in the original Designated Currency with an Interest Period of one month; 

(x) if the Borrower shall fail to specify a currency for any Eurocurrency Rate Advances, then the Eurocurrency Rate
Advances as requested shall be made in Dollars; 
 (xi) Revolving Advances may only be Converted or continued as
Revolving Advances; (xii) Swingline Advances may not be Converted or continued; and 
 (xiii) no Revolving Advance
may be Converted or continued as a Revolving Advance in a different currency, but instead must be prepaid in the original Designated Currency of such Revolving Advance and reborrowed in such new Designated Currency. 

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the
Borrower. 
 (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the
date of any Revolving Borrowing or Mandatory Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made
its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.2 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 Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to
immediately repay to the 

  
 34 












 
Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Overnight Rate for such day. If such
Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even
though not made on the same day as the other Advances comprising such Borrowing. 
 (f) Lender Obligations Several. The failure of
any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other
Lender to make the Advance to be made by such other Lender on the date of any Borrowing. 
 (g) Evidence of
Obligations.     
 (i) The Advances made by each Lender shall be evidenced by one or more accounts
or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by Administrative Agent and the Lenders shall be conclusive absent manifest error of the amount of the
Advances made by such Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing
with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the
Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender to the Borrower made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) the
applicable Note or Notes which shall evidence such Lender’s Advances to the Borrower in addition to such accounts or records. Each Lender may attach schedules to such Notes and endorse thereon the date, Type (if applicable), amount, currency
and maturity of its Advances and payments with respect thereto. 
 (ii) In addition to the accounts and records referred to
in subsection (i) above, each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline
Advances. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control
in the absence of manifest error. 
 Section 2.3 Fees. 

(a) Commitment Fees. Subject to Section 2.20(a)(iii), the Borrower agrees to pay to the Administrative Agent for the account of
each Lender a commitment fee (the “Commitment Fee”) equal to the Applicable Margin for Commitment Fees times the actual daily amount by which such Lender’s Revolving Commitment exceeds the sum of such Lender’s Revolving
Advances plus such Lender’s Pro Rata Share of the Letter of Credit Exposure, for the period from the Closing Date until the latest Maturity Date (including at any time during which one or more of the conditions in Article III is not met). The
Commitment Fees shall be due and payable quarterly in arrears on the tenth (10th) day after the end of each March, June, September and December, commencing September 30, 2017, and on each Maturity Date. For the avoidance of doubt, Swingline
Advances shall not reduce the amount of unused Revolving Commitment solely for purposes of calculating the Commitment Fee under this Section 2.3(a).  

  
 35 












 (b) Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent
for the pro rata benefit of the Lenders letter of credit fees in respect of all Letters of Credit outstanding at a rate per annum equal to the Applicable Margin for Eurocurrency Rate Advances calculated on the maximum amount available from time to
time to be drawn under such outstanding Letters of Credit. All such letter of credit fees shall be (i) calculated quarterly in arrears for the period ending on the last day of each March, June, September and December, commencing
September 30, 2017 and due and payable on the immediately following 10th Business Day, and (ii) calculated in arrears, and due and payable on, each Maturity Date. In addition, the Borrower agrees to pay to each Issuing Lender for its own
account fronting fees in respect of all Letters of Credit outstanding and issued by such Issuing Lender equal to the greater of (A) one-eighth percent (1/8%) per annum of the maximum amount available from
time to time to be drawn under such outstanding Letters of Credit and (B) $500, payable at issuance and on the earlier of each annual anniversary thereafter and on such Issuing Lender’s Maturity Date. The Borrower shall also pay to each Issuing
Lender for its own account such documentary, processing and other charges in connection with the issuance, amendment, transfer, modification of and draws under Letters of Credit assessed or incurred by such Issuing Lender from time to time. For
purposes of calculating the letter of credit fees, fronting fees and other fees under this Section 2.3(b), the face amount of each Letter of Credit made in a Foreign Currency shall be at any time the Dollar Amount of such Letter of Credit as
determined on the most recent Computation Date with respect to such Letter of Credit. 
 (c) Fee Letters. The Borrower agrees to pay
when due the fees set forth in the Fee Letters, in each case, pursuant to the terms thereof. 
 Section 2.4 Reduction of Revolving
Commitments. The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the Administrative Agent and the Lenders, to terminate in whole or reduce ratably in part the unused portion of the Revolving
Commitments; provided that, each partial reduction shall be in the aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. Any reduction or termination of the Revolving Commitments pursuant to this
Section 2.4 shall be permanent, with no obligation of the Lenders to reinstate such Revolving Commitments and the Commitment Fees provided for in Section 2.3(a) shall thereafter be computed on the basis of the Revolving Commitments, as so
reduced. 
 Section 2.5 Repayment of Advances. 

(a) Revolving Advances. The Borrower shall repay the outstanding principal amount of each Revolving Advance on each Maturity Date and,
for each Mandatory Revolving Borrowing made on or after the latest Maturity Date, on demand, and in any event, in the Designated Currency in which each such Advance was funded. 

(b) Swingline Advances. The Borrower shall repay the outstanding principal amount of each Swingline Advance on the earlier of
(i) the Swingline Due Date immediately following the date such Swingline Advance is made by the applicable Swingline Lender and (ii) the applicable Swingline Lender’s Maturity Date. 

  
 36 












 Section 2.6 Interest. The Borrower shall pay interest on the unpaid principal
amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum: 

(a) Adjusted Base Rate Advances. If such Advance is an Adjusted Base Rate Advance, a rate per annum equal at all times to the lesser of
(i) the Adjusted Base Rate in effect from time to time plus the Applicable Margin for Adjusted Base Rate Advances and (ii) the Maximum Rate, payable in arrears on the last Business Day of each calendar quarter, commencing with the calendar
quarter ending June 30, 2017, and on the date such Adjusted Base Rate Advance shall be paid in full, provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was
due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two
percent (2%) and (B) the Maximum Rate. 
 (b) Eurocurrency Rate Advances. If such Advance is a Eurocurrency Rate Advance, during
the Interest Period for such Advance, a rate per annum equal at all times to the lesser of (i) the Eurocurrency Rate for such Interest Period plus the Applicable Margin for Eurocurrency Rate Advances plus (in the case of a Eurocurrency Rate
Advance of any Lender which is lent from a Lending Office in the United Kingdom or a Participating Member State) the Mandatory Cost Rate and (ii) the Maximum Rate, payable in arrears on the last day of such Interest Period (provided that for
Eurocurrency Rate Advances with an Interest Period longer than three months, accrued but unpaid interest shall also be due and payable on each day prior to the last day of such Interest Period that occurs at intervals of three months’ duration
after the first date of such Interest Period), and on the date such Eurocurrency Rate Advance shall be paid in full; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such
payment was due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the greater of (1) the Adjusted Base Rate in effect from time to time plus the Applicable Margin for
Adjusted Base Rate Advances plus two percent (2%) and (2) the rate required to be paid on such Advance immediately prior to the date on which such amount became due (including the Applicable Margin and any Mandatory Cost Rate) plus two percent
(2%) and (B) the Maximum Rate. 
 (c) Swingline Advances. If such Advance is a Swingline Advance, a rate per annum equal at all
times to the lesser of (i) the Swingline Rate for such Swingline Advance and (ii) the Maximum Rate, payable quarterly in arrears on the last Business Day of each calendar quarter, commencing with the calendar quarter ending June 30,
2017, and on such applicable Swingline Lender’s Maturity Date; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in
full, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate. 

(d) Usury Recapture. As to each Lender, in the event the rate of interest chargeable under this Agreement or the Notes at any time is
greater than the Maximum Rate, the unpaid principal amount of Obligations owing to such Lender shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on such Obligations equals the amount of interest which would
have been paid or accrued on such Obligations if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of such Obligations, the total amount of interest paid or accrued under the
terms of this Agreement and the Notes as to any Lender is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall,
to the extent permitted by applicable Legal Requirements, pay the Administrative Agent for the account of such Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on
Obligations owing to such Lender if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Obligations if the rates of interest set forth in this Agreement had at all times been in
effect and (ii) the amount of interest actually paid or accrued under 

  
 37 












 this Agreement on such Obligations. In the event any Lender ever receives, collects or applies as interest
any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Obligations owing to it, and if no such principal is then outstanding, such excess or part
thereof remaining shall be paid to the Borrower. 
 (e) Other Amounts Overdue. If any amount payable under this Agreement other than
the Advances is not paid when due and payable, including accrued interest and fees, then such overdue amount shall accrue interest hereon due and payable on demand (i) if such amount is in Dollars, at a rate per annum equal to the lesser of
(A) Adjusted Base Rate plus the Applicable Margin for Adjusted Base Rate Advances plus two percent (2%) and (B) the Maximum Rate, from the date such amount became due until the date such amount is paid in full, and (ii) if such amount
is in a Foreign Currency, the lesser of (A) the greater of (1) the Adjusted Base Rate in effect from time to time plus the Applicable Margin for Adjusted Base Rate Advances plus two percent (2%) and (2) the overnight Eurocurrency Rate
plus the Applicable Margin for Eurocurrency Rate Advances and any Mandatory Cost Rate for Eurocurrency Rate Advances plus two percent (2%) and (B) the Maximum Rate. 

(f) Effect of Benchmark Transition Event. 

(i) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Credit Document, upon the
occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, the Administrative Agent and the Borrower may amend this Agreement to replace the Eurocurrency Adjusted Base Rate with
respect to any applicable currency with one or more Benchmark Replacements, as applicable (it being understood that all Advances denominated in a given currency for which the Eurocurrency Adjusted Base Rate is being replaced shall be subject to the
same Benchmark Replacement). Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all Lenders and the
Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Majority Lenders. Any such amendment with respect to an Early
Opt-in Election will become effective on the date that Lenders comprising the Majority Lenders have delivered to the Administrative Agent written notice that such Lenders accept such amendment. No replacement
of the Eurocurrency Adjusted Base Rate with a Benchmark Replacement pursuant to this Section 2.6(f) will occur prior to the applicable Benchmark Transition Start Date. 

(ii) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the
Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Credit Document, any amendments implementing such Benchmark Replacement
Conforming Changes will become effective without any further action or consent of any other party to this Agreement. 
 (iii)
Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (A) any occurrence of a Benchmark Transition Event or an Early
Opt-in Election, as applicable, and its related Benchmark Replacement Date and Benchmark Transition Start Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any
Benchmark Replacement Conforming Changes and (D) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or Lenders pursuant to this
Section 2.6(f), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from
taking any action, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this
Section 2.6(f). 

  
 38 












 (iv) Benchmark Unavailability Period. Upon the Borrower’s
receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a borrowing of, Conversion to or continuation of Eurocurrency Adjusted Base Rate Advances subject to such Benchmark Unavailability
Period to be made, Converted or continued during any such Benchmark Unavailability Period and, failing that, (A) in the case of a request for borrowing of, Conversion to or continuation of Advances denominated in Dollars, the Borrower will be
deemed to have converted any such request into a request for a borrowing of or Conversion to Adjusted Base Rate Advances and (B) in the case of a request for borrowing of, Conversion to or continuation of Advances denominated in any Agreed
Currency subject to such Benchmark Unavailability Period, the Borrower will be deemed to have converted any such request into a request for a borrowing of or Conversion to Adjusted Base Rate Advances denominated in Dollars. During any Benchmark
Unavailability Period, the component of Adjusted Base Rate based upon Daily One Month LIBOR will not be used in any determination of Adjusted Base Rate. 

Section 2.7 Prepayments. 

(a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this
Section 2.7. 
 (b) Optional Prepayments. The Borrower may elect to prepay any of the Advances, after giving notice thereof to
the Administrative Agent and the Lenders by 10:00 a.m. (Houston, Texas) for Adjusted Base Rate Advances, by 12:00 p.m. (Houston, Texas) for all other Advances denominated in Dollars and by 12:00 p.m. in the Applicable Time for Revolving Advances
denominated in Foreign Currencies and Swingline Advances made by Foreign Swingline Lenders (i) on the day of prepayment of any Swingline Advance, (ii) at least three Business Days’ prior to the day of prepayment of any Eurocurrency
Rate Advances and (iii) on the day of prepayment of any Adjusted Base Rate Advance. Such notice shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing, and must state the proposed date and aggregate principal
amount of such prepayment, whether such prepayment should be applied to reduce outstanding Revolving Advances or Swingline Advances, and if applicable, the relevant Interest Period for the Advances to be prepaid. If any such notice is given, the
Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, and shall also pay accrued interest to the date of such prepayment on the
principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date; provided, however, that (i) each partial prepayment of Eurocurrency Rate
Advances shall be in an aggregate principal amount of not less than $3,000,000 and in integral multiples of $1,000,000 in excess thereof, (ii) each partial prepayment of Adjusted Base Rate Advances shall be in an aggregate principal amount of
not less than $500,000 and in integral multiples of $100,000 in excess thereof, (iii) each partial prepayment of Swingline Advances shall be in an aggregate principal amount of not less than $500,000, and (iv) any prepayment of an Advance
shall be made in the Designated Currency in which such Advance was funded. Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any,
required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date. 

  
 39 












 (c) Ratable Payments. Each payment of any Advance pursuant to this Section 2.7
or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part. 

(d) Effect of Notice. All notices given pursuant to this Section 2.7 shall be irrevocable and binding upon the Borrower. 

Section 2.8 Breakage Costs. If (a) any payment of principal of any Eurocurrency Rate Advance is made other than on the last
day of the Interest Period for such Advance as a result of any payment hereunder or the acceleration of the maturity of the Obligations pursuant to Article VIII or otherwise; (b) the Borrower fails to borrow, Convert, continue, repay or prepay
any Eurocurrency Rate Advance on the date specified in any notice delivered pursuant hereto (other than default by a Lender); or (c) the Borrower fails to make a principal or interest payment with respect to any Eurocurrency Rate Advance on the
date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower (with a copy to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts
(without duplication of any other amounts payable in respect of breakage costs) required to compensate such Lender for any additional losses, out-of-pocket costs or
expenses which it may reasonably incur as a result of such payment or nonpayment, including any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired
by any Lender to fund or maintain such Advance. 
 Section 2.9 Increased Costs. 

(a) Increased Costs Generally. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement
against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (other than any change by way of imposition or increase of reserve requirements included in the calculation of the Eurocurrency Rate but
including any change or introduction which would result in the failure of the Mandatory Cost Rate, as calculated hereunder, to represent the cost to any Lender of complying with the requirements of the Bank of England and/or the Financial Services
Authority or the European Central Bank in relation to its making, funding or maintaining Eurocurrency Rate Advances) or any Issuing Lender; 

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses
(b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable
thereto; or 
 (iii) impose on any Lender or any Issuing Lender or the London interbank market any other condition, cost
or expense (other than Taxes) affecting this Agreement or Advances made by such Lender or any Letter of Credit or participation therein; 
 and the result
of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, Converting to, continuing or maintaining any Advance or of maintaining its obligation to make any such Advance, or to increase the cost to such
Lender, such Issuing Lender or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received
or receivable by such Lender, Issuing Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Issuing Lender or other Recipient, the Borrower will pay to such Lender, Issuing Lender
or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Issuing Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered. 

  
 40 












 (b) Capital Requirements. If any Lender or Issuing Lender determines that any Change
in Law affecting such Lender or Issuing Lender or any lending office of such Lender or such Lender’s or Issuing Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the
rate of return on such Lender’s or Issuing Lender’s capital or on the capital of such Lender’s or Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Revolving Commitments of such Lender or the
Advances made by, or participations in Letters of Credit or Swingline Advances held by, such Lender, or the Letters of Credit issued by any Issuing Lender, to a level below that which such Lender or Issuing Lender or such Lender’s or Issuing
Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Lender’s policies and the policies of such Lender’s or Issuing Lender’s holding company with respect
to capital adequacy), then from time to time the Borrower will pay to such Lender or Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Lender or such Lender’s or Issuing
Lender’s holding company for any such reduction suffered. 
 (c) Certificates for Reimbursement. A certificate of a Lender or
Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or Issuing Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower, shall be
conclusive absent manifest error. The Borrower shall pay such Lender or Issuing Lender, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof. 

(d) Delay in Requests. Failure or delay on the part of any Lender or Issuing Lender to demand compensation pursuant to this Section
shall not constitute a waiver of such Lender’s or Issuing Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or Issuing Lender pursuant to this Section for any increased
costs incurred or reductions suffered more than 180 days prior to the date that such Lender or Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such
Lender’s or Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to
include the period of retroactive effect thereof). 
 Section 2.10 Payments and Computations. 

(a) Payment Procedures. Except if otherwise set forth herein, the Borrower shall make each payment under this Agreement not later than
1:00 p.m. (Houston, Texas time) for payments due in Dollars and not later than 1:00 p.m. in the Applicable Time for payments due in Foreign Currencies (and payments due to Foreign Swingline Lenders related to Foreign Swingline Advances), on the day
when due in the Designated Currency as to outstanding Advances and Reimbursement Obligations, and in Dollars as to all other amounts, to the Administrative Agent at its Lending Office (or such other location as the Administrative Agent shall
designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the
Administrative Agent, the Issuing Lenders, or a specific Lender pursuant to Section 2.1(b), 2.3(b), 2.3(c), 2.6(d), 2.6(e), 2.8, 2.9, 2.11, 2.12, 2.13(d), 9.4 or 9.7 but after taking into account payments effected pursuant to Section 7.6)
to the Lenders in accordance with each Lender’s Pro Rata Share for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or any Issuing Lender to such Lender or such
Issuing Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. 

  
 41 












 (b) Computations. All computations of interest based on the Prime Rate, interest on
Swingline Advances and interest on Eurocurrency Rate Advances denominated in Pounds Sterling shall be made by the Administrative Agent (or with respect to each Swingline Advance, by the applicable Swingline Lender) on the basis of a year of 365 or
366 days, as the case may be. All computations of fees and interest based on the Eurocurrency Rate (other than as set forth in the immediately preceding sentence), Overnight Rate and the Federal Funds Rate shall be made by the Administrative Agent
on the basis of a year of 360 days. In any case, such computations shall be made for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each
determination by the Administrative Agent (or with respect to each Swingline Advance, by the applicable Swingline Lender) of an interest rate shall be conclusive and binding for all purposes, absent manifest error. 

(c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if
such extension would cause payment of interest on or principal of Eurocurrency Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day. 

(d) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the
date on which any payment is due to the Lenders that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative
Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative
Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent, at the Overnight Rate for such day. 
 (e) Application of Payments. Whenever any payment
received by the Administrative Agent under this Agreement is insufficient to pay in full all amounts then due and payable under this Agreement and Notes, such payment shall be distributed and applied by the Administrative Agent and the Lenders in
the following order: first, to the payment of fees and expenses due and payable to the Administrative Agent under and in connection with this Agreement or any other Credit Document; second, to the payment of all amounts due and payable
under Section 2.11(c), ratably among the Lenders in accordance with the aggregate amount of such payments owed to each such Lender; third, to the payment of fees due and payable pursuant to Section 2.3(b), ratably among the Issuing
Lenders in accordance with the aggregate amount of such payments owed to each such Issuing Lender; fourth, to the payment of all other fees due and payable under Section 2.3 ratably among the Lenders in accordance with their applicable
Revolving Commitments; and fifth, to the payment of the interest accrued on and the principal amount of all of the Advances, and the interest accrued on and the principal amount of all Reimbursement Obligations, regardless of whether any such
amount is then due and payable, ratably among the Lenders in accordance with the aggregate accrued interest plus the aggregate principal amount owed to such Lender. 

  
 42 












 Section 2.11 Taxes. 

(a) Defined Terms. For purposes of this Section 2.11, the term “Lender” includes any Issuing Lender and the term
“applicable law” includes FATCA. 
 (b) Payments Free of Taxes. Any and all payments by or on account of any obligation of
the Borrower under any Credit Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires
the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the
relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such
deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. 

(c) Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with
applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. 
 (d)
Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts
payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative
Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 
 (e) Indemnification by the Lenders.
Each Lender shall severally indemnify the Administrative Agent, within 30 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the
Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.6(e) relating to the maintenance
of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Credit Document, and any reasonable expenses arising therefrom or with
respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be
conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Credit Document or otherwise payable by the Administrative Agent to the
Lender from any other source against any amount due to the Administrative Agent under this paragraph (e). 
 (f) Evidence of
Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.11, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 

  
 43 












 (g) Status of Lenders. 

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any
Credit Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the
Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such
other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or
information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.11(g)(ii)(A),
(ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or
commercial position of such Lender. 
 (ii) Without limiting the generality of the foregoing, in the event that the Borrower
is a U.S. Person, 
 (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on
or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form
W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax; 

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the
Borrower or the Administrative Agent), whichever of the following is applicable; 
 (1) in the case of a Foreign
Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Credit Document, executed copies of IRS Form W-8BEN-E or IRS Form W-8BEN, as applicable, establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article
of such tax treaty and (y) with respect to any other applicable payments under any Credit Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant
to the “business profits” or “other income” article of such tax treaty; 
 (2) executed copies of
IRS Form W-8ECI; 
 (3) in the case of a Foreign Lender claiming the benefits
of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank”
within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent 

  
 44 












 shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the
Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN-E or IRS Form W-8BEN, as applicable; or 

(4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E or IRS Form W-8BEN, as applicable, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are
claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner; 

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

(D) if a payment made to a Lender under any Credit Document would be subject to U.S. federal withholding Tax imposed by
FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the
Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by
Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under
FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any
amendments made to FATCA after the date of this Agreement. 
 Each Lender agrees that if any form or certification it previously delivered expires or
becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. 

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a
refund of any Taxes as to which it has been indemnified pursuant to this Section 2.11 (including by the payment of additional amounts pursuant to this Section 2.11), it shall pay to the indemnifying party an amount equal to such refund
(but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including
Taxes) of such indemnified party and without interest (other than 

  
 45 












 any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying
party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event
that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying
party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to
indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require
any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. 

(i) Survival. Each party’s obligations under this Section 2.11 shall survive the resignation or replacement of the
Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Revolving Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document. 

(j) For purposes of determining withholding Taxes imposed under FATCA, the Borrower and the Administrative Agent shall treat (and the Lenders
hereby authorize the Administrative Agent to treat) the Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i). 

Section 2.12 Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any
change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Lending Office to perform its obligations under this Agreement
to maintain any Eurocurrency Rate Advances of such Lender then outstanding hereunder or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign
Currency in the applicable interbank market, then, notwithstanding anything herein to the contrary, the Borrower shall, if demanded by such Lender in its notice, no later than 12:00 p.m. (Houston, Texas time), (a) if not prohibited by any Legal
Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurocurrency Rate Advance of such Lender or (b) if prohibited by any Legal Requirement
to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice from such Lender, then (i) with respect to Revolving Advances denominated in a Foreign
Currency, prepay such Eurocurrency Rate Advances of such Lender then outstanding and which are denominated in such affected currency or currencies together with all accrued interest on the amount so prepaid, and amounts, if any, required to be paid
pursuant to Section 2.8 as a result of such prepayment being made on such date, and (ii) with respect to Revolving Advances denominated in Dollars, Convert all such Eurocurrency Rate Advances of such Lender then outstanding to Adjusted
Base Rate Advances and pay accrued interest on the principal amount Converted to the date of such Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such Conversion being made on such date. Each Lender
agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would
not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

 Section 2.13 Letters of Credit. 

(a) Issuance of Letters of Credit. Each Issuing Lender, the Lenders and the Borrower agree that effective as of the Closing Date, any
Existing Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement as Letters of Credit. From time to time from the date of this Agreement until ten days before such
applicable Issuing Lender’s Maturity Date, at the written request of the Borrower given to the applicable Issuing Lender and to the Administrative Agent not later than (i) 12:00 p.m. (Houston, Texas time) on the third Business Day before the
date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in a Foreign Currency and (ii) 12:00 p.m. (Houston, Texas time) on the second Business Day (or such later time and date as may be agreed to among the Borrower,
the applicable Issuing Lender and the Administrative Agent) before the date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in Dollars, the requested Issuing Lender shall, on any Business Day and on the terms and
conditions hereinafter set forth (and, if applicable, subject to the terms of the applicable Letter of Credit), issue, increase, decrease, amend, or extend the expiration date of, Letters of Credit for the account of the Borrower (for its own
benefit or for the benefit of any of its Subsidiaries); provided that Barclays Bank PLC shall only be obligated to issue standby Letters of Credit. Promptly after receipt by the applicable Issuing Lender of such request, the applicable
Issuing Lender will confirm with the Administrative Agent that the Administrative Agent has also received such request and, if not, the applicable Issuing Lender will notify the Administrative Agent of the contents thereof. With respect to any
issuance of or increase to a Letter of Credit, unless the applicable Issuing Lender has received notice in writing from the Administrative Agent (including at the request of any Lender) at least one Business Day prior to the requested date of the
proposed issuance or increase, directing the applicable Issuing Lender not to issue or increase such Letter of Credit as a result of the limitations set forth clause 2.13(b)(i) below then, subject to the terms and conditions hereof, the applicable
Issuing Lender will issue or increase such Letter of Credit as requested by the Borrower. Letters of Credit shall be denominated in any Agreed Currency. 

(b) Limitations. No Letter of Credit will be issued (or deemed issued as to any Existing Letters of Credit), increased, or extended
(i) if such issuance, increase, or extension would cause the sum of the Letter of Credit Exposure plus the aggregate Dollar Amount of all outstanding Revolving Advances and Swingline Advances at such time to exceed the Letter of Credit
Maximum Amount; (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) sixty months after the date of issuance thereof and (B) twenty-four months after such applicable Issuing Lender’s Maturity
Date; (iii) unless such Letter of Credit (or, if applicable, the amendment to a Letter of Credit) is in form and substance reasonably acceptable to the applicable Issuing Lender in its sole discretion; (iv) unless the Borrower has
delivered to the applicable Issuing Lender a completed and executed letter of credit application on such Issuing Lender’s standard form, which shall contain terms no more restrictive than the terms of this Agreement; (v) unless such Letter
of Credit is governed by the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600 (“UCP”), the International Standby Practices (ISP 98), International
Chamber of Commerce Publication No. 590 (“ISP”) or any successor to the UCP or ISP and, to the extent not inconsistent therewith, the New York Uniform Commercial Code, or such other state’s Uniform Commercial Code
acceptable to the Administrative Agent, the applicable Issuing Lender and the Borrower, in each case as in effect from time to time; (vi) if such issuance, increase, or extension would violate one or more policies of such applicable Issuing
Lender that are applicable to letters of credit generally or (vii) if any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain an Issuing Lender from issuing or providing such
Letter of Credit, or any Legal Requirements applicable to such Issuing Lender shall prohibit the issuance or provision of such type of Letter of Credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender with
respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuing Lender is not 

  
 47 












 otherwise compensated hereunder) not in effect on the date hereof or shall impose upon such Issuing Lender
any unreimbursable loss, cost or expense which was not applicable on the date hereof and which such Issuing Lender in good faith deems material. If the terms of any letter of credit application referred to in the foregoing clause (iv) conflicts
with the terms of this Agreement, the terms of this Agreement shall control. 
 (c) Participations. With respect to each Letter of
Credit described on Schedule 1.1(c) which is outstanding on the Closing Date, each Lender is deemed to have purchased a participation in the related Letter of Credit Exposure equal to such Lender’s Pro Rata Share of such Letter of Credit
Exposure on the Closing Date. On the date of the issuance or increase of any Letter of Credit on or after the Closing Date, each Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have
purchased from such Issuing Lender a participation in the Letter of Credit Exposure related to the Letters of Credit issued by such Issuing Lender equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be
in accordance with the terms of this Agreement. Each Issuing Lender shall promptly deliver to the Administrative Agent by telex, telephone, or facsimile (or by e-mail with a return receipt requested) which the
Administrative Agent will promptly deliver to each such participant Lender, a notice of each Letter of Credit of such Issuing Lender issued, increased or decreased, and the Administrative Agent shall also notify each Lender of the actual amount of
such Lender’s participation in such Letter of Credit. Each Lender’s obligation to purchase participating interests pursuant to this Section, to make a Mandatory Revolving Borrowing as set forth in clause (d) below, to reimburse such
Issuing Lender for such Lender’s Pro Rata Share of any payment under a Letter of Credit by such Issuing Lender not reimbursed in full by the Borrower, and to fund its participation interests in Letters of Credit as set forth below, shall be
absolute and unconditional and shall not be affected by any circumstance, including (i) any of the circumstances described in paragraph (f) or (e) below, (ii) the occurrence and continuance of a Default, (iii) an adverse change
in the financial condition of the Borrower, (iv) any deposit of cash or other securities as collateral or the provision of any other support for the Borrower’s reimbursement obligations related thereto, (v) any termination of this
Agreement other than a termination in writing agreed to by each Issuing Lender which expressly provides for a termination of the Lenders’ reimbursement obligations owing to the Issuing Lenders hereunder, and (vi) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing; provided that, a Lender may have a claim against an Issuing Lender for any such circumstance, happening or event constituting or arising from gross negligence or willful
misconduct on the part of the such Issuing Lender. 
 (d) Reimbursement. Upon receipt from the beneficiary of any Letter of Credit of
any notice of a drawing under such Letter of Credit, the applicable Issuing Lender shall, within the period, if any, stipulated by the terms and conditions of such Letter of Credit, examine such notice of drawing. After such examination, the Issuing
Lender shall promptly notify the Borrower and the Administrative Agent thereof (which notification the Administrative Agent will promptly forward to the Lenders). No later than 11:00 a.m. on the date of any payment to be made by such Issuing Lender
under a Letter of Credit, the Borrower agrees to pay to such Issuing Lender an amount equal to any amount paid or to be paid by such Issuing Lender on such date under or in respect of such Letter of Credit and in the currency paid or to be paid by
such Issuing Lender. Notwithstanding the foregoing, if, after the issuance of any Letter of Credit denominated in a Foreign Currency, such currency ceases to be an Agreed Currency as provided in the definition of Agreed Currency, then all payments
to be made by the Borrower hereunder in such currency shall instead be made when due (either directly by the Borrower or through a deemed borrowing under clause (i) below) in Dollars in an amount equal to the Dollar Amount (as of the date of
repayment) of such payment due, it being the intention of the parties hereto that the Borrower take all risks of the imposition of any such currency control or exchange regulations. In the event an Issuing Lender makes a payment pursuant to a
request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower as required herein, such Issuing Lender shall give 

  
 48 












 notice of such payment to the Administrative Agent (which the Administrative Agent will promptly forward to
the Lenders). In such event, the Borrower shall be deemed to have requested a Mandatory Revolving Borrowing consisting of (i) for unreimbursed drawings under Letters of Credit denominated in Dollars or in a Foreign Currency which ceased to be
an Agreed Currency, Adjusted Base Rate Advances, and (ii) for unreimbursed drawings under Letters of Credit denominated in Foreign Currencies, Eurocurrency Rate Advances in such Agreed Currency and in the amount of such unreimbursed amount with
an Interest Period of one month; provided that, if the Revolving Commitments have terminated or otherwise expired, such Eurocurrency Rate Advances shall bear interest at the overnight Eurocurrency Rate. The applicable Issuing Lender shall give the
Administrative Agent notice of such deemed Borrowing (A) by 12:00 p.m. (Houston, Texas time) on the date before the proposed Borrowing is to be made in the case of an Adjusted Base Rate Advance or Eurocurrency Rate Advances bearing interest at
the overnight Eurocurrency Rate and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency with an Interest
Period of one month (which notice the Administrative Agent shall promptly give to each Lender). Each Lender shall, no later than 1:00 p.m. on the Business Day specified in such notice, promptly make such funds available to the applicable Issuing
Lender, in the applicable currency and in an amount equal to such Lender’s Pro Rata Share of the unreimbursed amount. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders
to record and otherwise treat each payment under a Letter of Credit not immediately reimbursed by the Borrower as a Borrowing comprised of Adjusted Base Rate Advances or Eurocurrency Rate Advances, as applicable, to the Borrower. If for any reason
such Mandatory Revolving Borrowing cannot be made by any Lender, the request for such Mandatory Revolving Borrowing submitted by the applicable Issuing Lender as set forth herein shall be deemed to be a request by such Issuing Lender that each of
the Lenders fund its risk participation in the relevant Letter of Credit and each Lender’s payment to the Administrative Agent for the account of the applicable Issuing Lender pursuant to this clause (d) shall be deemed payment in respect
of such participation. If the funds are not made available by a Lender to the applicable Issuing Lender on the required date (either as the making of a Revolving Advance or the funding of its participation interest in such Letters of Credit), such
Lender shall pay interest thereon to the applicable Issuing Lender at a rate per annum equal to the applicable Overnight Rate. At any time after any Lender has funded its participation in a Letter of Credit, if the applicable Issuing Lender receives
any payment on the applicable Reimbursement Obligation from the Borrower, such Issuing Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time
during which such Lender’s participation was funded) in the same funds as those received by such Issuing Lender. All overdue Reimbursement Obligations of the Borrower shall bear interest as set forth in
 Section 2.6(e). 

(e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances: 

(i) any lack of validity or enforceability of any Letter of Credit Documents; 

(ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents; 

(iii) the existence of any claim, set-off, defense or other right which the
Borrower or any Lender or any other Person may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any Issuing Lender or any other
Person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction; 

  
 49 












 (iv) any statement, draft or any other document presented under such
Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent an Issuing Lender would not be liable therefor pursuant to the following
paragraph (f); 
 (v) payment by an Issuing Lender under such Letter of Credit against presentation of a draft or certificate
which does not comply with the terms of such Letter of Credit; or 
 (vi) any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing; 
 provided, however, that nothing contained in this paragraph (e) shall be
deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit. 
 (f) Liability of Issuing
Lenders. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. No Issuing Lender nor any of its officers or directors shall be liable or
responsible for, and the Borrower’s obligations hereunder shall not be affected by: 
 (i) the use which may be
made of any Letter of Credit, any transfer of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; 

(ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should
prove to be in any or all respects invalid, insufficient, fraudulent or forged; 
 (iii) payment by any Issuing Lender
against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; 

(iv) any adverse change in the relevant exchange rates or in the availability of the relevant Agreed Currency to the
Borrower or in the relevant currency markets generally; or 
 (v) any other circumstances whatsoever in making or
failing to make payment under any Letter of Credit (INCLUDING ANY ISSUING LENDER’S OWN NEGLIGENCE), 
 except that the Borrower
shall have a claim against such Issuing Lender, and such Issuing Lender shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves
were caused by such Issuing Lender’s willful misconduct or gross negligence. In furtherance and not in limitation of the foregoing clause (f), the Issuing Lenders may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or information to the contrary and may refuse to accept documents that are not in strict conformity with the terms of the Letter of Credit, and any such acceptance or refusal shall
not be deemed to constitute gross negligence or willful misconduct. 

  
 50 












 (g) Cash Collateral Account. The Borrower shall, (i) within 10 days prior to
the latest Maturity Date and (ii) at any time, if an Event of Default has occurred and is continuing, on the Business Day the Borrower receives written notice from an Issuing Lender or the Administrative Agent that collateralization is being
required pursuant to Section 7.2(b) or Section 7.3(b), either (A) provide Cash Collateral in an amount equal to the Letter of Credit Exposure as of such date or (B) cause to be issued an irrevocable standby letter of credit in
favor of the applicable Issuing Lender and issued by a bank or other financial institution acceptable to such Issuing Lender and the Administrative Agent to support the full amount of the Letter of Credit Exposure as of such date. With respect to
Letters of Credit issued in Foreign Currencies, if the Borrower elects to provide Cash Collateral pursuant to clause (A) above, then at the election of the Administrative Agent, the Borrower shall be required to either (1) deposit cash
with the Administrative Agent in the Designated Currencies for the Letters of Credit or (2) deposit cash with the Administrative Agent in Dollars equal to the Dollar Amount of the Letter of Credit Exposure and, thereafter, deposit additional
cash in Dollars at any time and from time to time as may be reasonably requested by the Administrative Agent in order to protect against the results of exchange rate fluctuations. 

(h) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of
any obligations of, or is for the account of, a Subsidiary of the Borrower, the Borrower shall be obligated to reimburse the applicable Issuing Lender hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges
that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries. 

(i) Information to Administrative Agent from Issuing Lenders. For purposes of calculating outstandings and Letters of Credit issued
under this Agreement (i) on each March 31, June 30, September 30 and December 31, commencing June 30, 2017, and (ii) from time to time as the Administrative Agent may request, each Issuing Lender shall provide the
Administrative Agent with a daily log, in form and detail reasonably acceptable to the Administrative Agent, setting forth the Dollar Amount of all outstanding Letters of Credit issued by such Issuing Lender using the Exchange Rate as most recently
determined by the Administrative Agent. 
 Section 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) on account of its Advances or its share of Letter of Credit Obligations in excess of its Pro Rata Share of payments
on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, then such Lender shall notify the Administrative Agent and the other Lenders and forthwith purchase from the other Lenders, such participations in the Advances
made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably in accordance with the requirements of this Agreement with each of them; provided, however,
that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such
Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such
recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required
repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered; provided further that, the provisions of this paragraph shall not be construed to apply
to (A) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (B) the application of Cash Collateral to
address the fronting exposure of Defaulting Lenders as provided in Section 2.16, or (C) any 

  
 51 












 
payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in Swingline Advances and Letters of Credit to any assignee
or participant, other than to the Borrower or any of its Subsidiaries or Affiliates (as to which the provisions of this paragraph shall apply). The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this
Section 2.14 may, to the fullest extent permitted by law, unless and until rescinded as provided above, exercise all its rights of payment (including the right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. 
 Section 2.15
Increase of Revolving Commitment. 
 (a) At any time prior to the latest Maturity Date, the Borrower may effectuate no more than two
increases in the aggregate Revolving Commitments by an aggregate amount not greater than $1,000,000,000 (any such increase, a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its
sole discretion, may determine whether to participate in such Commitment Increase and the amount by which it is willing to increase its Revolving Commitment) or one or more other banks or other financial institutions (reasonably acceptable to the
Administrative Agent, the Issuing Lenders and the Swingline Lenders) that at the time agree, in the case of any such bank or financial institution that is an existing Lender to increase its Revolving Commitment as such Lender shall so select (an
“Increasing Lender”) and, in the case of any other such bank or financial institution (an “Additional Lender”), to become a party to this Agreement; provided, however, that (i) the aggregate Revolving
Commitments shall not at any time exceed $3,000,000,000 and (ii) the minimum amount of each such Commitment Increase shall not be less than $100,000,000. The sum of the increases in the Revolving Commitments of the Increasing Lenders plus the
Revolving Commitments of the Additional Lenders upon giving effect to the Commitment Increase shall not in the aggregate exceed the amount of the Commitment Increase. The Borrower shall provide prompt notice of any proposed Commitment Increase
pursuant to this Section 2.15 to the Administrative Agent and the Lenders. 
 (b) Any Commitment Increase shall become effective
upon (i) the receipt by the Administrative Agent of (A) an agreement in form and substance reasonably satisfactory to the Administrative Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the new
Revolving Commitment of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon each Lender, and (B) such evidence of
appropriate authorization on the part of the Borrower with respect to the Commitment Increase and such opinions of counsel for the Borrower with respect to the Commitment Increase, if any, as the Administrative Agent may reasonably request, and
(ii) receipt by the Administrative Agent of a certificate (the statements contained in which shall be true) of a Responsible Officer of the Borrower stating that both before and after giving effect to such Commitment Increase (A) no Event
of Default has occurred and is continuing, and (B) all representations and warranties made by the Borrower in this Agreement are true and correct in all material respects (unless already qualified by materiality or Material Adverse Effect in
the text thereof, in which case, such representations and warranties are true and correct in all respects), unless such representation or warranty relates to an earlier date, in which case such representation or warranty shall be true and correct in
all material respects (unless already qualified by materiality or Material Adverse Effect in the text thereof, in which case, such representations and warranties are true and correct in all respects) as of such earlier date, and except that for
purposes of this Section 2.15, the representations and warranties contained in Section 4.6 shall be deemed to refer to the most recent statements furnished pursuant to subsection (b) of Section 5.6. 

  
 52 












 (c) The Borrower shall prepay any Advances outstanding on the effective date of such
Commitment Increase to the extent necessary to keep the outstanding Revolving Advances ratable with any revised Pro Rata Share arising from any non-ratable increases in the Revolving Commitments under this
Section 2.15; provided that such prepayment may be made with the proceeds of additional Revolving Advances made hereunder (reflecting such increase in Revolving Commitments). The Administrative Agent and the Lenders hereby agree that the
minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. 

(d) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and
payments of interest on the Advances shall take into account the actual Revolving Commitment of each Lender and the principal amount outstanding of each Advance made by such Lender during the relevant period of time. 

(e) Effective with any Commitment Increase, each Lender’s share of the Letter of Credit Exposure and participations in respect of
Swingline Advances on such date shall automatically be deemed to equal such Lender’s Pro Rata Share of such Letter of Credit Obligations and participations in respect of Swingline Advances (such Pro Rata Share for such Lender to be determined
as of the effective date of such Commitment Increase in accordance with its Revolving Commitment on such date as a percentage of the aggregate Revolving Commitments on such date) without further action by any party. 

Section 2.16 Mitigation Obligations; Lender Replacement; Termination of Defaulting Lender. 

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.9, or requires the
Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, then such Lender shall (at the request of the Borrower) use reasonable efforts to
designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.9 or 2.11, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 

(b) Right to Replace. The Borrower shall have the right to replace each Lender affected by a condition under Sections 2.2(c)(v),
2.2(c)(viii), 2.9, 2.11 or 2.12, each Lender that is a Defaulting Lender, a Non-Approving Lender or a Non-Consenting Lender and each Lender that is due interest based on
the Mandatory Cost Rate (each such Lender, an “Affected Lender”) in accordance with the procedures in this Section 2.16 and provided that (i) no reduction of the total Revolving Commitments occurs as a result thereof,
(ii) such Affected Lender has declined or is unable to designate a different lending office in accordance with Section 2.16(a) to remedy any such condition, (iii) the condition entitling the Borrower to require such replacement has
not ceased to apply and (iv) such assignment does not conflict with applicable law. 
 (c) Procedure. Any assumptions of
Revolving Commitments pursuant to this Section 2.16 shall be made by the purchasing Lender or Eligible Assignee and the selling Lender by entering into an Assignment and Acceptance and by following the procedures in Section 9.6 for adding
a Lender; provided that the Borrower or the assignee (if such assignee is not the Administrative Agent or its Affiliate) shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 9.6(a), which may be waived by
the Administrative Agent in its sole discretion. In connection with the increase of the Revolving Commitments of any Lender or the introduction of any Eligible Assignee pursuant to the foregoing paragraph (b), each Lender with an increased Revolving
Commitment and each new Eligible Assignee shall purchase from the Affected Lenders at par such Lender’s or such new 

  
 53 












 Lender’s ratable share of the outstanding Advances, funded participations, accrued interest thereon and
accrued fees of the Affected Lenders (and provided that the Borrower shall be obligated to pay any other amounts payable to any such Affected Lender under the Credit Documents, including pursuant to Section 2.8 hereof) and shall be
automatically deemed to have assumed such Lender’s or such new Lender’s ratable share of the Affected Lenders’ participations in Letter of Credit Exposure. 

(d) Termination of Defaulting Lender. 

(i) Entire Revolving Commitment. At any time when a Lender is then a Defaulting Lender, the Borrower, at the
Borrower’s election, may elect to terminate such Defaulting Lender’s Revolving Commitment hereunder; provided that (A) the Borrower must elect to terminate such Defaulting Lender’s entire Revolving Commitment, (B) the
Borrower shall pay to the Administrative Agent all amounts owed by the Borrower to such Defaulting Lender in its capacity as a Lender under this Agreement and under the other Credit Documents (excluding any amounts owing under Section 2.8 as
result of such payment) and shall, to the extent such Defaulting Lender’s ratable share of the Letter of Credit Exposure has not been, or has only partially been, reallocated pursuant to Section 2.20(a)(iv), deposit with the Administrative
Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s Fronting Exposure (after giving effect to any partial reallocation pursuant to Section 2.20(a)(iv)), (C) a Defaulting Lender’s
Revolving Commitment may be terminated by the Borrower under this Section 2.16(d) only if at such time, the Borrower has elected, or is then electing, to terminate the Revolving Commitments of all then existing Defaulting Lenders and
(D) such termination shall not be permitted if a Default has occurred and is continuing. Upon written notice to the Defaulting Lender and the Administrative Agent of the Borrower’s election to terminate such Defaulting Lender’s
Revolving Commitment pursuant to this clause (i) and the payment and deposit of amounts required to be made by the Borrower under clause (B) above, (1) such Defaulting Lender shall cease to be a “Lender” hereunder for all
purposes except that such Lender’s rights and obligations as a Lender under Sections 2.9, 2.11, 8.5 and 9.7 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender”
hereunder, (2) such Defaulting Lender’s Revolving Commitment shall be deemed terminated in whole and (3) such Defaulting Lender shall be relieved of its obligations hereunder as a “Lender” except as to its obligations under
Section 8.5 with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, provided that any such termination will not be deemed to be a waiver or release of any claim by the
Borrower, the Administrative Agent, any Swingline Lender, any Issuing Lender or any Lender against such Defaulting Lender. 

(ii) Unused Commitment Termination. The Borrower may terminate the unused amount of the Revolving Commitment of any
Lender that is a Defaulting Lender upon not less than 30 Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Lenders thereof), and in such event the provisions of Section 2.20(a)(ii) will apply to all
amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts); provided that (i) no Event of Default shall have occurred and
be continuing, (ii) such termination shall not be deemed to be a waiver or release of any claim the Borrower, the Administrative Agent, any Issuing Lender, the Swingline Lender or any Lender may have against such Defaulting Lender, and
(iii) to the extent such Defaulting Lender’s ratable share of the Letter of Credit Exposure has not been, or has only partially been, reallocated pursuant to Section 2.20(a)(iv), the Borrower shall deposit with the Administrative
Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s Fronting Exposure (after giving effect to any partial reallocation pursuant to Section 2.20(a)(iv)).

 Section 2.17 Currency Fluctuations, Mandatory Prepayments and Deposits in the Cash
Collateral Accounts. 
 (a) Not later than 1:00 p.m., Houston, Texas time, on each Computation Date, the Administrative Agent shall
determine the Exchange Rate as of such Computation Date and give notice thereof to the Borrower, each Lender, Swingline Lender and Issuing Lender. The Exchange Rate so determined shall become effective on the first Business Day after such
Computation Date and shall remain effective through the next succeeding Computation Date. 
 (b) If, on any Computation Date, the Dollar
Amount of the sum of the outstanding principal amount of Revolving Advances plus the outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure exceeds an amount equal to 102% of the aggregate Revolving Commitments then in
effect, then the Administrative Agent shall give notice thereof to the Borrower and the Lenders, and the Borrower shall within five (5) Business Days thereafter prepay Advances, or if the Advances have been repaid or prepaid in full, make
deposits into the Cash Collateral Account, such that after giving effect to such prepayment of Advances or deposits into the Cash Collateral Account, the Dollar Amount of the sum of the outstanding principal amount of Revolving Advances plus the
outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure does not exceed the aggregate Revolving Commitments then in effect. 

(c) If any currency shall cease to be an Agreed Currency as provided in the last sentence of the definition of “Agreed Currency”,
then promptly, but in any event within five (5) Business Days of receipt of the notice from the Administrative Agent provided for in such sentence, the Borrower shall repay all Advances funded and denominated in such affected currency or
Convert such Advances into Advances in Dollars or another Agreed Currency, subject to the other terms set forth in Article II. 
 (d) Each
prepayment pursuant to this Section 2.17 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being
made on such date. 
 (e) Each payment of any Advance pursuant to this Section 2.17 or any other provision of this Agreement shall be
made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part and each payment of an Advance shall be made in the Designated Currency in which such Advance was funded. 

Section 2.18 Market Disruption. Notwithstanding the satisfaction of all conditions referred to herein with respect to any proposed
Borrowing consisting of Eurocurrency Rate Advances denominated in any Foreign Currencies, if there shall occur on or prior to the date of such Borrowing any change in national or international financial, political or economic conditions or currency
exchange rates or exchange controls which would in the reasonable opinion of the Administrative Agent or the Majority Lenders, make it impracticable for such Borrowing to be denominated in the Agreed Currency designated by the Borrower, then the
Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, and such Advances shall not thereafter be denominated and funded in such Agreed Currency but shall, except as otherwise set forth in Article II, be made on
such date in Dollars, in an aggregate principal amount equal to the Dollar Amount of the aggregate principal amount specified in the related Notice of Borrowing, as the case may be, as Adjusted Base Rate Advances to the Borrower, unless the Borrower
notifies the Administrative Agent at least one Business Day before such date that it elects not to borrow on such date. 

  
 55 












 Section 2.19 Extension of Maturity Date. 

(a) Not later than 30 days prior to each anniversary of the Amendment No. 1 Effective Date, the Borrower may, upon notice to the
Administrative Agent (which shall promptly notify the Lenders), request that each Lender extend such Lender’s then existing Maturity Date (i) for an additional one year from such Lender’s Maturity Date then in effect, (ii) for
such additional number of days which would cause its Maturity Date to be the latest Maturity Date then in effect, or (iii) for such additional number of days which would cause its Maturity Date to be one year after the latest Maturity Date then
in effect (each Lender’s then existing Maturity Date being referred to herein as its “Present Maturity Date” and such Lender’s proposed extended Maturity Date being referred to herein as its “Extended Maturity
Date”). This option may only be exercised (x) after the first anniversary of the Amendment No. 1 Effective Date, (y) once during any twelve (12) month period, and (z) twice during the term of this Agreement. Within
20 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not responding
within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses. Notwithstanding anything herein to the contrary, no
Extended Maturity Date shall be a date later than five years from the applicable Extension Closing Date. 
 (b) Subject to the satisfaction
of the condition precedent set forth below, the Maturity Date of each extending Lender shall be extended only if the consenting Lenders (the “Consenting Lenders”) constitute Majority Lenders. If so extended, the Present Maturity
Date, as to the Consenting Lenders, shall be extended to the applicable Extended Maturity Date effective as of the first date on which such necessary consent required pursuant to this clause (b) is obtained and the condition precedent specified
below in this clause (b) is satisfied with respect to the applicable extension (such date, the “Extension Closing Date”). All non-consenting Lenders (“Non-Consenting Lenders”) shall continue to be subject to such Lender’s Present Maturity Date. The Borrower shall pay or prepay all Advances, interest thereon and all other amounts due each Non-Consenting Lender on or before the Present Maturity Date, and, if after giving effect thereto, the Outstandings exceed the Revolving Commitments of the Consenting Lenders the Borrower shall prepay the Advances
(or if no Advances are then outstanding, Cash Collateralize the Letter of Credit Exposure) in the amount of such excess, together with all accrued and unpaid interest thereon. The Administrative Agent and the Borrower shall promptly confirm to the
Lenders such extension and each Consenting Lender’s Extended Maturity Date. As a condition precedent to any such extension the Borrower shall deliver to the Administrative Agent a certificate of the Borrower (in form and substance satisfactory
to the Administrative Agent and in sufficient copies for each Lender) signed by a Responsible Officer of the Borrower (i) certifying that attached thereto is evidence that such extension is within the Borrower’s corporate authority and has
been duly authorized by appropriate governing action and proceedings and (ii) certifying that, before and after giving effect to such extension, (A) the representations and warranties contained in Article IV and the other Credit Documents
are true and correct in all material respects (unless already qualified by materiality or Material Adverse Effect in the text thereof, in which case, such representations and warranties are true and correct in all respects), except to the extent
that such representations and warranties expressly relate solely to an earlier date, in which case they shall have been true and correct in all material respects (unless already qualified by materiality or Material Adverse Effect in the text
thereof, in which case, such representations and warranties are true and correct in all respects) as of such earlier date, and except that for purposes of this Section 2.19, the representations and warranties contained in Section 4.6 shall
be deemed to refer to the most recent statements furnished pursuant to subsection (b) of Section 5.6, and (B) no Default has occurred and is continuing. If the Maturity Date has been extended, then on such applicable Present Maturity
Date, each Consenting Lender shall automatically be deemed to have purchased participations in each Letter of Credit, the related Letter of Credit Exposure, and each Swingline Advance equal to such 

  
 56 












 Consenting Lender’s Pro Rata Share thereof after giving effect to the departure of the Non-Consenting Lenders and the elimination of their Revolving Commitments, but only to the extent that such reallocation does not cause the Aggregate Exposure of any Lender whose Revolving Commitment does not
terminate on such Maturity Date to exceed such Lender’s Revolving Commitment. If the reallocation described in this Section 2.19(b) cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy
available to the Administrative Agent, the Lenders, or any Issuing Lender hereunder or under applicable Legal Requirement, (I) first, prepay Swingline Advances in an amount equal to the portion of each Swingline Lender’s Fronting Exposure
that was attributable to each Lender whose Commitment terminates on such Maturity Date but was not so reallocated and (II) second, Cash Collateralize each Issuing Lender’s Fronting Exposure in an amount equal to the portion of such Issuing
Lender’s Fronting Exposure (plus all related fees and expenses with respect to such Letters of Credit then outstanding over their remaining terms) that was attributable to each Lender whose Commitment terminates on such Maturity Date but was
not so reallocated. 
 (c) If any Lender’s Maturity Date is extended in accordance with this Section 2.19, immediately upon the
effectiveness of each such extension, Schedule 1.1(a) hereof shall be amended and restated to set forth all Lenders and their respective Revolving Commitments and Maturity Dates after giving effect to such extension. 

(d) This Section shall supersede any provisions in Section 2.14 or Section 9.1 to the contrary. 

(e) The Borrower shall prepay any Advances outstanding on the Present Maturity Date (and pay any additional amounts required pursuant to
Section 2.8) or borrow additional amounts to the extent necessary to keep outstanding Revolving Advances ratable with any revised and new Revolving Commitment of all Consenting Lenders effective as of the Present Maturity Date. 

Section 2.20 Defaulting Lender. 

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender
becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law: 

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or
consent with respect to this Agreement shall be restricted as set forth in the definition of Majority Lenders. 
 (ii)
Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or
otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 7.6 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts
owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Lender or Swingline Lender hereunder; third, to Cash
Collateralize, on a pro rata basis, the Issuing Lenders’ and the Swingline Lenders’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.20(b); fourth, as the Borrower may request (so long as no
Default has occurred and is continuing), to the funding of any Advance in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so
determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in 

  
 57 












 
order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Advances under this Agreement and (y) Cash Collateralize the Issuing
Lenders’ and the Swingline Lenders’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement and Swingline Advances made under this Agreement, in accordance with
Section 2.20(b); sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or Swingline Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Lenders or
Swingline Lenders against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default has occurred and is continuing, to the payment of any amounts owing
to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth,
to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advances or Letters of Credit in respect of which such Defaulting Lender has
not fully funded its appropriate share, and (y) such Advances were made or the related Letters of Credit were issued at a time when the conditions set forth in Sections 3.2 and 3.3 were satisfied or waived, such payment shall be applied solely
to pay the Advances of, and Letter of Credit Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Letter of Credit Obligations owed
to, such Defaulting Lender until such time as all Advances and funded and unfunded participations in Letters of Credit and Swingline Advances are held by the Lenders pro rata in accordance with the Revolving Commitments without giving effect to
Section 2.20(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.20(a)(ii)
shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto. 
 (iii)
Certain Fees. 
 (A) No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which
that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender). 

(B) Each Defaulting Lender shall be entitled to receive fees set forth in Section 2.3(b) for any period during which that
Lender is a Defaulting Lender only to the extent allocable to its Pro Rata Share of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.20(b). 

(C) With respect to any fee not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower
shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in Letters of Credit that
has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Lender the amount of any such fee otherwise payable to such Defaulting Lender to the extent
allocable to such Issuing Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee. 

  
 58 












 (iv) Reallocation of Participations to Reduce Fronting Exposure. All
or any part of such Defaulting Lender’s participation in Letters of Credit and Swingline Advances shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares
of the aggregate amount of the Revolving Commitment (calculated without regard to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) the conditions set forth in Sections 3.2 and 3.3 are satisfied at the time of
such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such
reallocation does not cause any Non-Defaulting Lender’s Pro Rata Share of the Aggregate Exposure to exceed such Non-Defaulting Lender’s Revolving Commitment.
Subject to Section 9.20, no reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation. 

(b) Cash Collateral; Prepayment of Swingline. At any time that there shall exist a Defaulting Lender, within one Business Day following
the written request of the Administrative Agent or any Issuing Lender (with a copy to the Administrative Agent), the Borrower shall Cash Collateralize the Issuing Lenders’ Fronting Exposure, as requested, with respect to such Defaulting Lender
(determined after giving effect to Section 2.20(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the applicable Minimum Collateral Amount. At any time that there shall exist a Defaulting Lender,
within one Business Day following the written request of the Administrative Agent or any Swingline Lender (with a copy to the Administrative Agent), the Borrower shall either (i) Cash Collateralize the Swingline Lenders’ Fronting Exposure,
as requested, with respect to such Defaulting Lender (determined after giving effect to Section 2.20(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the applicable Minimum Collateral Amount or
(ii) prepay Swingline Advances in an amount equal to the Swingline Lenders’ Fronting Exposure as to Swingline Advances. 

(i) Grant of Security Interest. The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting
Lender to the extent not prohibited under applicable law, hereby grants to the Administrative Agent, for the benefit of the Issuing Lenders and the Swingline Lenders, and agrees to maintain, a first priority security interest in all such Cash
Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of Letter of Credit Obligations and Swingline Advances, to be applied pursuant to clause (ii) below and the introductory paragraph of this
Section 2.20(b). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent, the Issuing Lenders, and the Swingline Lenders, or that the total
amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to
eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender). 
 (ii)
Application. Notwithstanding anything to the contrary contained in this Agreement but subject to the introductory paragraph of this Section 2.20(b), (A) Cash Collateral provided under this Section 2.20(b) in respect of Letters of
Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Letter of Credit Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such
obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein and (B) Cash Collateral provided under this Section 2.20(b) in respect of Swingline Advances
shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Swingline Advances (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for
which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein. 

  
 59 












 (iii) Cash Collateral, Repayment of Swingline Advances. If the
reallocation described in Section 2.20(a)(iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first prepay or Cash Collateralize the
Swingline Advances as set forth above in this Section 2.20(b), and (y) second, Cash Collateralize the Issuing Lenders’ Fronting Exposure as set forth above in this Section 2.20(b). 

(iv) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce any Issuing
Lender’s or any Swingline Lender’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.20(b) following (i) the elimination of the applicable Fronting Exposure (including by the
termination of Defaulting Lender status of the applicable Lender) with respect to Letters of Credit and Swingline Advances, or (ii) the determination by the Administrative Agent, each Swingline Lender and each Issuing Lender that there exists
excess Cash Collateral; provided that, the Person providing Cash Collateral, the Issuing Lenders and the Swingline Lenders may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations. 

(c) Defaulting Lender Cure. If the Borrower, the Administrative Agent and each Swingline Lender and each Issuing Lender agree in
writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include
arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be
necessary to cause the Advances and funded and unfunded participations in Letters of Credit and Swingline Advances to be held pro rata by the Lenders in accordance with the Revolving Commitments (without giving effect to Section 2.20(a)(iv)),
whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and
provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that
Lender’s having been a Defaulting Lender. 
 (d) New Swingline Advances/Letters of Credit. So long as any Lender is a Defaulting
Lender, (i) no Swingline Lender shall be required to fund any Swingline Advances unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Advance and (ii) no Issuing Lender shall be required to
issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

of property, the making of any investment, the giving of any guaranty, the assumption of any obligation or the rendering of any service) with any of their Affiliates unless such transaction or series of transactions is on terms (taken as a whole)
substantially as favorable to the Borrower or the Subsidiary, as applicable, as those that could reasonably be expected to be obtained in a comparable arm’s length transaction with a Person that is not such an Affiliate; provided that, the

 ARTICLE VIII 

AGENCY AND ISSUING LENDER PROVISIONS 

Section 8.1 Authorization and Action. Each Lender hereby 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 other Credit Documents as are delegated to the Administrative Agent by the terms hereof and of the other Credit Documents, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Credit Document (including enforcement or collection of the Obligations), the Administrative Agent shall not be required to exercise 

  
 77 












 any discretion or take any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders or all Lenders, and such instructions shall be binding upon all Lenders and all holders of the Obligations; provided, however, that
Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, any other Credit Document, or applicable Legal Requirements. It is understood and
agreed that the use of the term “agent” herein or in any other Credit Documents (or any other similar term) 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 as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. 

Section 8.2 Administrative Agent’s Reliance, Etc. Neither Administrative Agent nor any of its respective directors, officers,
agents or employees shall be liable for any action taken or omitted to be taken (INCLUDING THE ADMINISTRATIVE AGENT’S OWN NEGLIGENCE) by it or them under or in connection with this Agreement or the other Credit Documents, except for its
or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative Agent receives written
notice of the assignment or transfer thereof signed by such payee and in form reasonably satisfactory to the Administrative Agent; (b) may consult with legal counsel (including 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 in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender and
shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Credit Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement or any other Credit Document on the part of the Borrower or its Subsidiaries or to inspect the property (including the books and records) of the Borrower or its Subsidiaries;
(e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Credit Document; and (f) shall incur no liability under or in respect of
this Agreement or any other Credit Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or
parties. 
 Section 8.3 The Administrative Agent and its Affiliates. With respect to its Revolving Commitments, the Advances
made by it and the Letters of Credit issued by it, the Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an agent hereunder. The term
“Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. Administrative Agent and its respective Affiliates may accept deposits from, lend money to, own
securities of, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower or any of its Subsidiaries, and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as
if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders. 
 Section 8.4
Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender and based on the financial statements referred to in Section 4.6 and such
other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the
Arrangers or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. 

  
 78 












 Section 8.5 Indemnification. The Lenders severally agree to indemnify the
Administrative Agent, each Arranger, each Swingline Lender and each Issuing Lender (to the extent not reimbursed by the Borrower), according to their respective Pro Rata Shares from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including legal fees) which may be imposed on, incurred by, or asserted against the Administrative Agent, such Arranger or such Issuing Lender
in its capacity as such in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by the Administrative Agent, such Arranger, such Swingline Lender or such Issuing Lender under this Agreement
or any other Credit Document (INCLUDING THE ADMINISTRATIVE AGENT’S, THE ARRANGER’S, SUCH SWINGLINE LENDER’S OR SUCH ISSUING LENDER’S OWN NEGLIGENCE), provided that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements found by a final judgment by a court of competent jurisdiction to have resulted from the Administrative Agent’s, such
Arranger’s, such Swingline Lender’s or such Issuing Lender’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to (a) reimburse the Administrative Agent promptly upon demand for its
ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery,
modification or amendment of this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower and (b) reimburse the Administrative Agent promptly upon demand for its
ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the administration or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document, in each case to the extent that the Administrative Agent is not reimbursed for
such expenses by the Borrower. All obligations of the Lenders provided in this Section 8.5 shall survive any termination of this Agreement and repayment in full of the Obligations. All amounts due under this Section 8.5 shall be payable
not later than 30 days after demand therefor. 
 Section 8.6 Successor Administrative Agent and Issuing Lenders. 

(a) Administrative Agent and any Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower. The
Administrative Agent and any Issuing Lender may be removed at any time with or without cause by the Majority Lenders upon receipt of written notice from such Majority Lenders to such effect. Any Issuing Lender designated in writing by the Borrower
as provided in the definition of “Issuing Lender” may be removed at any time with or without cause by the Borrower. Upon receipt of notice of any such resignation or removal (other than a removal of an Issuing Lender by the Borrower), the
applicable Majority Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if an Event of Default has not occurred and is not continuing, the consent of the Borrower, which consent shall not be unreasonably
withheld or delayed. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring or removed Administrative Agent’s or
Issuing Lender’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring or removed Administrative Agent or Issuing Lender may, on behalf of the Lenders and
the Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be a commercial bank meeting the financial requirements of an Eligible Assignee and, in the case of a Issuing Lender, a Lender. Upon the acceptance of any
appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring or removed Administrative Agent or Issuing Lender (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent or Issuing Lender), and the retiring or removed Administrative Agent


  
 79 












 
or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring or removed Issuing Lender shall remain the
Issuing Lender with respect to any Letters of Credit issued by such Issuing Lender and outstanding on the effective date of its resignation or removal and the provisions affecting such Issuing Lender with respect to such Letters of Credit shall
inure to the benefit of the retiring or removed Issuing Lender until the termination of all such Letters of Credit and the payment of all outstanding Obligations owing to such Issuing Lender. After any retiring or removed Administrative Agent’s
or Issuing Lender’s resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative
Agent or Issuing Lender under this Agreement and the other Credit Documents (including rights to indemnity payments owed to the retiring or removed Administrative Agent or Issuing Lender). 

(b) Any Swingline Lender may resign at any time by giving 30 days’ prior notice to the Administrative Agent, the Lenders and the
Borrower. After the resignation of such Swingline Lender hereunder, the resigning Swingline Lender shall remain a party hereto and shall continue to have all the rights and obligations of such Swingline Lender under this Agreement and the other
Credit Documents with respect to Swingline Advances made by it prior to such resignation, but shall not be required to make any additional Swingline Advances. Upon such notice of resignation, the Borrower shall have the right to designate any other
Lender as a replacement Swingline Lender with the consent of such Lender and the Administrative Agent. 
 Section 8.7 Co-Lead
Arrangers, Joint Book Runners, other Agency Titles. The Arrangers, Joint Book Runners and any other agents identified on the cover sheet hereof (other than the Administrative Agent) shall have no duties, obligations or liabilities hereunder in

by the Administrative Agent or any of its respective Affiliates in connection with the Platform. 
 (ii) Each Lender agrees that notice to it
(as provided in the next sentence) (a “Notice”) specifying that any Communication has been posted to the Platform shall for purposes of this Agreement constitute effective delivery to such Lender of such information, documents or other
materials comprising such Communication. Each Lender agrees (A) to notify, on or before the date such Lender becomes a party to this Agreement, the Administrative Agent in writing of such Lender’s
e-mail address to which a Notice may be sent (and from time to time thereafter to ensure that the Administrative Agent have on record an effective e-mail address for
such Lender) and (B) that any Notice may be sent to such e-mail address. 
 Section 9.3
No Waiver; Remedies. No failure on the part of any Lender, the Administrative Agent, or any Issuing Lender to exercise, and no delay in exercising, any right hereunder or under any other Credit Document shall operate as a waiver thereof; nor
shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in this Agreement and the other Credit Documents are cumulative and not exclusive of any
remedies provided by law. 
 Section 9.4 Costs and Expenses. The Borrower agrees to pay on demand (a) all out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, execution, delivery, modification and amendment of this Agreement, the Notes
and the other Credit Documents, (b) all out-of-pocket costs and expenses of the Issuing Lenders and Swingline Lenders in connection with the administration of this

by the Borrower and the Administrative Agent, and when the Administrative Agent shall have, as to each Lender, either received a counterpart hereof executed by such Lender or been notified by such Lender that such Lender has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, each Arranger, each Issuing Lender, each Swingline Lender and each Lender and their respective successors and assigns, except that the Borrower

 Section 9.6 Lender Assignments and Participations. 

(a) Assignments. Any Lender may assign to one or more banks or other entities all or any portion of its rights and obligations under
this Agreement (including all or a portion of its Revolving Commitment, the Advances owing to it, the Notes held by it, if any, and the participation interest in the Letter of Credit Obligations held by it); provided, however, that
(i) each such assignment shall be of a constant, and not a varying, percentage of all of such Lender’s rights and obligations under this Agreement as a Lender and shall involve a ratable assignment of such Lender’s Revolving
Commitment and such Lender’s Revolving Advances and shall be in an amount not less than $5,000,000, (ii) the amount of the resulting Revolving Commitment and Revolving Advances of the assigning Lender (unless it is assigning all its Revolving
Commitment) and the assignee Lender pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000, (iii) each such assignment shall be to an
Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the applicable Notes, if any,
subject to such assignment, (v) each Eligible Assignee shall pay to the Administrative Agent a $4,000 administrative fee; and (vi) the Administrative Agent shall promptly deliver a copy of the fully executed Assignment and Acceptance to
the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof,
(A) the assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and (B) such Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to
the benefits of Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 with respect to facts and circumstances occurring prior to the effective date of such assignment. Notwithstanding anything herein to the contrary, any Lender may assign, as collateral or
otherwise, any of its rights under the Credit Documents to any Federal Reserve Bank. 
 (b) Term of Assignments. By executing and
delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender
makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or
the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together
with copies of the financial statements referred to in Section 4.6 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such
assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this
Agreement are required to be performed by it as a Lender. 

  
 83 












 (c) The Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses
of the Lenders, and the Revolving Commitments of, and principal amounts (and stated interest) of the Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall
be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent, the Issuing Lenders, and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes
of this Agreement. At any reasonable time and from time to time upon reasonable prior notice, the Register shall be available (i) for inspection by the Borrower, (ii) for inspection by each Lender as to its Revolving Commitment and
principal amount of Advances owing to it, and (iii) for inspection by each Issuing Lender and each Swingline Lender for purposes of determining each Lender’s participation interest in Letters of Credit and Swingline Advances. The Borrower
hereby agrees that the Administrative Agent acting as its non-fiduciary agent solely for the purpose set forth above in this clause (c), shall not subject the Administrative Agent to any fiduciary or other
implied duties, all of which are hereby waived by the Borrower. 
 (d) Procedures. Upon its receipt of an Assignment and Acceptance
executed by a Lender and an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit
A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower. 

(e) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell
participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this
Agreement (including all or a portion of its Commitment and/or the Advances owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent, the Issuing Lenders, the Swingline Lenders and the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity and other obligations under Section 8.5 with respect to any payments made by such
Lender to its Participant(s). 
 Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such
Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver that requires the approval of all affected Lenders in accordance with the terms of Section 9.1 that affects such Participant. The Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.8, 2.9 and 2.11 (subject to the requirements and limitations therein) (it being understood that the documentation required under Section 2.11(g) shall be delivered to the participating Lender) to
the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.6(a); provided that such Participant (A) agrees to be subject to the provisions of Section 2.16 as if it were an assignee under
Section 9.6(a); and (B) shall not be entitled to receive any greater payment under Sections 2.9 or 2.11, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such
entitlement to receive a greater payment results from a 

  
 84 












 
Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable
efforts to cooperate with the Borrower to effectuate the provisions of Section 2.16 with respect to any Participant. To the extent permitted by Legal Requirement, each Participant also shall be entitled to the benefits of Section 7.6
as though it were a Lender; provided that such Participant agrees to be subject to Section 2.14 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a
non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the
Advances or other obligations under the Credit Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any
Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Credit Document) to any Person except to the extent that such disclosure is necessary to
establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant
Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the
contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. The Borrower hereby agrees that each Lender acting as its non-fiduciary agent solely for the purpose set forth above in this clause (e), shall not subject such Lender to any fiduciary or other implied duties, all of which are hereby waived by the Borrower. 

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this
Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto. 
 (g) Information. Any Lender may furnish any information
concerning the Borrower or any of its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the provisions of Section 9.12. 

(h) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such
assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon
distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent,
the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities
then owed by such Defaulting Lender to the Administrative Agent, each Issuing Lender, each Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all
Advances and participations in Letters of Credit and Swingline Advances in accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become
effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. Except to the
extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. 

  
 85 












 Section 9.7 Indemnification. The Borrower shall indemnify the Administrative
Agent, each Arranger, each Lender (including any lender which was a Lender hereunder prior to any full assignment of its Revolving Commitment), each Issuing Lender, each Swingline Lender and each affiliate thereof and their respective directors,
officers, employees and agents from, and discharge, release, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, insofar as such losses, liabilities, claims or damages
arise out of or result from (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or any other transactions
contemplated hereby, (ii) any actual or proposed use by the Borrower or any Affiliate of the Borrower of the proceeds of any Advance or Letter of Credit, (iii) any breach by the Borrower of any provision of this Agreement or any other
Credit Document, (iv) any Environmental Claim or requirement of Environmental Laws concerning or relating to the present or previously-owned or operated properties, or the operations or business, of the Borrower or any of its Subsidiaries, or
(v) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, and the Borrower shall reimburse the Administrative Agent, each Arranger, the Issuing Lender, each Swingline
Lender and each Lender, and each affiliate thereof and their respective directors, officers, employees and agents, upon demand for any reasonable out-of-pocket expenses
(including legal fees) incurred in connection with any such losses, liabilities, claims, damages, investigation, litigation, Environmental Claim or requirement, or other proceeding; and EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES,
CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES FOUND BY A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE
RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED. All amounts due under this Section 9.7 shall be payable not later than 30 days after demand therefor. 

Section 9.8 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page of this Agreement
by facsimile or other electronic imaging means (e.g. “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement. 

Section 9.9 Survival of Representations, etc. All representations and warranties contained in this Agreement or made in writing by
or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Lenders, none of which
investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 shall survive any termination of this Agreement and
repayment in full of the Obligations. 
 Section 9.10 Severability. In case one or more provisions of this Agreement or the
other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable Legal Requirement, the validity, legality and enforceability of the remaining provisions contained herein or therein shall not be affected or
impaired thereby. 
 Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and
performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable Legal Requirements of the
State of Texas and the United States of America from time to time in effect. In furtherance thereof, each Lender and the Borrower stipulate and 

  
 86 












 agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall
ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all
charges which constitute interest under such laws that are contracted for, charged or received under this Agreement. In the event that the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this
Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Obligations (or, if the applicable Obligations shall have been paid in full,
refunded to the Borrower). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith. 

Section 9.12 Confidentiality. None of the Administrative Agent, Issuing Lenders or Lenders shall disclose any Confidential
Information to any Person without the consent of the Borrower, other than (a) to the Administrative Agent’s, Issuing Lender’s or Lender’s Affiliates and their officers, directors, employees, agents and advisors, (b) to
actual or prospective Eligible Assignees and participants and their officers, directors, employees, agents and advisors, (c) to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization
transaction related to the obligations under this Agreement, and then, in any event, only on a confidential basis, (d) as required by any law, rule or regulation or judicial process, (e) as requested or required by any state, Federal or
foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Issuing Lender, such Lender or Administrative Agent, (f) to insurers,
insurance brokers or direct or indirect providers of credit protection when required by it, provided that, prior to any such disclosure, such Person shall undertake to preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (g) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality
of any Confidential Information relating to the Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (h) in connection with any litigation or proceeding to which Administrative Agent, such Issuing Lender or
such Lender or any of its Affiliates may be a party or (i) in connection with the exercise of any right or remedy under this Agreement or any other Credit Document. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this
Agreement shall (a) restrict the Administrative Agent, any Issuing Lender or any Lender from providing information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff;
(b) require or permit the Administrative Agent, any Issuing Lender or any Lender to disclose to the Borrower that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or
permit the Administrative Agent, any Issuing Lender or any Lender to inform the Borrower of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action.

conflicts or choice of law principles thereof.

Issuing Lender, each Swingline Lender and each Lender consents, for itself and in respect of its property, to the non-exclusive jurisdiction of those courts. The Borrower, the Administrative Agent, each
Issuing Lender, each Swingline Lender and each Lender irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any
action or proceeding in such jurisdiction in respect of this Agreement or any other Credit Document or other document related thereto. 

(c) The Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such
process to it at the address specified for it in this Agreement.

Lender to bring any action or proceeding against the Borrower in the courts of any other jurisdiction. 
 Section 9.14 Waiver of
Jury Trial. THE BORROWER, THE ISSUING LENDERS, THE SWINGLINE LENDERS, THE LENDERS
AND THE ADMINISTRATIVE AGENT HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT

ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF, THIS
AGREEMENT OR ANY OTHER CREDIT DOCUMENT, ANY ADVANCE OR LETTER OF
CREDIT OR THE USE OF THE PROCEEDS THEREOF.  

Section 9.16 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from
the Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall
be that at which in accordance with usual and customary banking procedures the Administrative Agent could purchase the specified currency with such other currency at any of the Administrative Agent’s offices in the United States of America on
the Business Day preceding that on which final, non-appealable judgment is given. The obligations of the Borrower in respect of any sum due to any Lender, any Issuing Lender or the Administrative Agent
hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender, such Issuing Lender or the Administrative Agent (as the case
may be) of any sum adjudged to be so due in such other currency such Lender, such Issuing Lender or the Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such
other currency. If the amount of the specified currency so purchased is less than the sum originally due to such 

  
 88 












 Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency, the
Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender, such Issuing Lender or the Administrative Agent, as the case may be, against such loss,
and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other
Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.14, each Lender, Issuing Lender or the Administrative Agent, as the case may be, agrees to promptly remit such excess to the
Borrower. All obligations of the Borrower provided in this Section 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations. 

Section 9.17 Headings Descriptive. The headings of the several Sections and paragraphs of the Agreement are inserted for
convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

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

 (ii) a conversion of all, or a portion of, such liability into
shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be

 Section 9.22 Acknowledgement Regarding Any Supported QFCs. To the extent that
the Credit Documents provide support, through a guarantee or otherwise, for Financial Contracts or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and, each such QFC, a “Supported
QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the FDIC under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the
regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Credit Documents and any Supported QFC
may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): 

(a) In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding
under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing
such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such
interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special
Resolution Regime, Default Rights under the Credit Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such
Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Credit Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is
understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support. 

(b) As used in this Section 9.22, the following terms have the following meanings: 

“BHC Act Affiliate” of a party means an “affiliate” (as such term is defined under, and interpreted
in accordance with, 12 U.S.C. 1841(k)) of such party. 
 “Covered Entity” means any of the following: 

(i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b);

 (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b);
or 
 (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §
382.2(b). 
 “Default Right” has the meaning assigned to that term in, and shall be interpreted in
accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. 

  
 91 












 “QFC” has the meaning assigned to the term “qualified
financial contract” in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D). 
 THIS WRITTEN
AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT
