Summary of terms of Global Crossing Senior Leadership Performance Program

 Exhibit 10.11 
  
 Senior Leadership Performance Program 
  
 This special Performance Program provides the opportunity for additional cash and equity awards at the time the Company reaches critical
financial milestones. 
  
 Highlights of the program are as follows: 

	 	•	 	The Performance Program is subject to all the terms and conditions of the 2003 Global Crossing Limited Stock Incentive Plan, as amended. 

  

	 	•	 	Performance Based—Target performance to attaining Positive EBITDA and Positive Cash Flow by December 31, 2006. Prorated payment is made when each independent and equally
weighted target is reached. Business goal of Positive Cash Flow or Positive EBITDA must be met for all three months within a quarter or for two consecutive quarters ending on or prior to December 31, 2006 before corresponding payment will be made.

  

	 	•	 	Payments would be combination of cash and stock, i.e., 50% Cash, 50% Stock. Must be on payroll when performance results are attained and payment made. 

  

	 	•	 	Award value will be equal to your annual bonus potential at target as of the effective date of this program. 

  

	 	•	 	Key element—the number of restricted stock units granted will be based on closing stock price on day of Board approval; quantity to be granted will not change based on
fluctuations in share price after day of approval; therefore, the value received is appropriately impacted by changes in stock performance. 

  

	 	•	 	Senior Leadership Performance Program is in effect until key financial goals are attained or December 31, 2006 whichever comes first. Until December 31, 2006, the Compensation
Committee of the Global Crossing Limited Board of Directors has the ability to review and postpone the sustained performance period as outlined above. 

  

	 	•	 	This special one-time program is in addition to the corporate annual bonus program and any other long-term incentive grants. Target opportunities for future periods may be modified
to ensure total compensation is appropriate with regards to market. 

  
 This program is not a contract. The Compensation Committee of the Board of Directors may, in its sole discretion, make any determination that it deems necessary or desirable for the administration of this program. Nothing in this program
will in any way be deemed to establish an employment relationship on a basis other than terminable at will. 
  
  
 Overview: 
  
 Global Crossing offers this performance-based compensation program for retaining and motivating key executives to achieve the
corporation’s strategic direction. This special one-time program is designed to align key executives to work towards the common goals of the corporation. 
  

Goals: 
  
 Attain Positive EBITDA and Positive Cash Flow by December 31, 2006. These objectives are independent with equal weighting. For each objective, the result must be met for all three months within a quarter
or for two consecutive quarters before corresponding payment will be made. Prorated payments will be made when each independent objective is reached. 
  

	 	•	 	EBITDA excludes future stock-based compensation expense; calculated using $18M annual accrual for incentive compensation, regardless of the actual amount of such expense.

  

	 	•	 	Cash Use excludes all cash costs associated with existing or new financing facilities (including principal, interest and fees), includes cash capex. 

  

	 	•	 	The Compensation Committee may calculate performance without regard to extraordinary items. 

  
 Eligibility: 
  
 Select members of Global Crossing’s senior management team identified at time of program approval and that are actively employed at the time of payment are eligible
as participants in this program. 
  
 Calculation: 
  
 Eligible award value will be equal to the executive’s annual target bonus potential as
of the effective date of this program. 
  
 Payments will be made as a combination
of 50% cash and 50% stock. The quantity of shares available for each eligible executive will be based on the economic value of the stock units on November 19, the day on which the Board approved the program. This economic value equals $14.90 per
share (the closing stock price on that day) multiplied by approximately 90% (the discount factor used in the program design valuation model to give effect to certain risk assumptions).Summary of Executive Officer and Non-employee Director Compensation

 Exhibit 10.5 
  
 Summary of Executive Officer and Non-employee Director Compensation 
  
 Set forth below is a summary of the compensation paid by Dril-Quip, Inc. (the “Company”) to its executive officers
and non-employee directors as of the date of filing of the Company’s Annual Report on Form 10-K. For more information regarding executive officer and director compensation, please read “Election of Directors—Director
Compensation,” “—Executive Compensation,” and
 “—Employment Agreements” contained in the Company’s proxy statement for its 2005 Annual Meeting of Stockholders to be filed with the SEC pursuant to Regulation
14A. 
  
 Executive Officers. 
  
 Each of the Company’s Co-Chief Executive Officers (the
“Co-CEOs”) are compensated in accordance with the employment agreements entered into with the Company prior to the closing of the Company’s initial public offering. Each of these agreements provides for an annual base salary, as well
as an annual performance bonus for each 12-month period based on (i) the Company’s performance in the 12-month period ending December 31 against the Company’s annual budget and (ii) the Company’s return on capital compared to that of
a peer group of companies for the 12-month period ending September 30. In addition, each agreement provides for an annual grant of a number of options under the Company’s incentive plan equal to the employee’s base salary multiplied by
three and divided by the market price of the Company’s Common Stock on the grant date. Each agreement also requires the Company to maintain a flexible perquisites spending account in the amount of $25,000 each year for each of the Co-CEOs for
use in paying for membership dues, costs associated with purchasing or leasing an automobile, financial counseling, tax return preparation and mobile phones. The Company is required to pay the unused and remaining balances of such accounts annually
to the Co-CEOs. 
  
 Each Co-CEO currently receives a base salary
of $469,000. For the 2004 bonus period, each Co-CEO received a bonus of $269,000. On October 28, 2004, the Company entered into letter agreements with each of the Co-CEOs pursuant to which the Co-CEOs waived their rights to receive stock option
awards in 2004 under their respective employment agreements in light of the current uncertainty surrounding stock option expensing. 
  
 The Company’s Chief Financial Officer (the “CFO”) is compensated with a base salary and annual bonus as determined by the Co-CEOs and
approved by the Company’s Compensation Committee. The CFO currently receives a base salary of $177,000. For 2004, the CFO received a bonus of $50,000. 
  
 Non-Employee Directors. 
  
 The Company’s non-employee directors receive an annual fee of $50,000, plus a fee of $1,000 for attendance at each Board of Directors meeting and
$1,000 for each committee meeting, unless the committee meeting is held on the same day as the Board of Directors meeting. All directors are reimbursed for their out-of-pocket expenses and other expenses incurred in attending meetings of the Board
or committees thereof and for other expenses incurred in their capacity as directors.Second Amended and Restated Credit Agreement

 “ABR Payment Date” means (i) the last Business Day of March, June, September and December of each year, beginning March 31, 2005, and (ii) any day on which past due interest or principal is owed under the Notes and is
unpaid. If the terms of any Loan Document provide that payments of interest or principal on the Notes shall be deferred from one ABR Payment Date to another day, such other day shall also be an ABR Payment Date. 
  
 “Affiliate” means, as to any Person, each other Person that
directly or indirectly (through one or more intermediaries or otherwise) controls, is controlled by, or is under common control with, such Person. A Person shall be deemed to be “controlled by” any other Person if such other Person

 ARTICLE II - The Loans 
  
 Section 2.1. Commitments to Make Loans; Notes; Participate in Letters of Credit. Subject to the terms and conditions hereof, each Lender severally
agrees to make loans to Borrower (herein called such Lender’s “Loans”) upon Borrower’s request from time to time during the Commitment Period, provided that subject to Sections 3.3, 3.4 and 3.6, all Lenders are requested
to make Loans of the same Type (or participate in Letters of Credit) in accordance with their respective Percentage Shares and as part of the same Borrowing. No Lender shall be permitted or required to (a) make any Loan if, after giving effect
thereto (i) the Facility Usage would exceed the lowest of (A) the Borrowing Base determined as of the date on which the requested Loans are to be made, (B) the Commitment or (C) the Facility Amount, (ii) the Loan by such Lender would exceed such
Lender’s Percentage Share of the aggregate amount of Loans then requested from all Lenders, or (iii) the sum of the aggregate outstanding principal amount of all Loans of such Lender together with such Lender’s Percentage Share of Letter
of Credit Outstandings would exceed such Lender’s Percentage Share of the lowest of (A) the Borrowing Base then outstanding, (B) the Commitment or (C) the Facility Amount; or (b) issue (in the case of an Issuer) or participate in (in the case
of a Lender) any Letter of Credit if, after giving effect thereto (i) the Facility Usage would exceed the lowest of (A) the Borrowing Base determined as 

  

 19 

 
of the date on which the requested Letter of Credit is to be issued, (B) the Commitment or (C) the Facility Amount; (ii) such Lender’s Percentage Share
of all Letter of Credit Outstandings together with the aggregate outstanding principal amount of all Loans of such Lender would exceed such Lender’s Percentage Share of the lowest of (A) the Borrowing Base then outstanding, (B) the Commitment
or (C) the Facility Amount; or (iii) all Letter of Credit Outstandings would exceed $90,000,000. The aggregate amount of all Loans in any Borrowing of ABR Loans must be greater than or equal to $500,000 (any higher, in multiples of $100,000) or must
equal the remaining availability under the Borrowing Base. The aggregate amount of all Loans in any Borrowing of Eurodollar Loans must be greater than or equal to $500,000 (any higher, in multiples of $100,000) or must equal the remaining
availability under the Borrowing Base. Borrower may have no more than five (5) Borrowings of Eurodollar Loans outstanding at any time. The obligation of Borrower to repay to each Lender the aggregate amount of all Loans made by such Lender, together
with interest accruing in connection therewith, shall be evidenced by a single promissory note (herein called such Lender’s “Note”) made by Borrower payable to the order of such Lender in the form of Exhibit A with appropriate
insertions. The amount of principal owing on any Lender’s Note at any given time shall be the aggregate amount of all Loans theretofore made by such Lender plus such Lender’s Percentage Share of the Letter of Credit Outstandings minus all
payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein, with Eurodollar Loans bearing interest at the Eurodollar Rate and ABR Loans bearing
interest at the Alternate Base Rate (subject to the applicability of the Default Rate as provided for herein or in the Notes and limited by the provisions of Section 10.9). Subject to the terms and conditions hereof, Borrower may borrow, repay, and
reborrow hereunder. 
  
 Section 2.2. Requests for New
Loans. Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Loans to be advanced by Lenders. Each such notice constitutes a “Borrowing Notice” hereunder and
must: 
  
 (a) specify (i) the aggregate amount of
any such Borrowing of new ABR Loans and the date on which such ABR Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the
first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and 
  
 (b) be received by Agent not later than 12:00 noon, New York City time, on (i) the day on which any such ABR Loans are to be made, or (ii)
the third Business Day preceding the day on which any such Eurodollar Loans are to be made. 
  
 Each such written request or confirmation must be made in the form and substance of the “Borrowing Notice” attached hereto as Exhibit B, duly completed. Each such telephonic request shall be deemed a
representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Agent shall give each Lender prompt notice of the terms
thereof. If all conditions precedent to such new Loans have been met, each Lender will on the date requested promptly remit to Agent at Agent’s office in Houston, Texas, the amount of such Lender’s new Loan in immediately available funds,
and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Loans have been neither met nor waived as 

  

 20 

 
provided herein, Agent shall promptly make such Loans available to Borrower. Unless Agent shall have received prompt notice from a Lender that such Lender
will not make available to Agent such Lender’s new Loan, Agent may in its discretion assume that such Lender has made such Loan available to Agent in accordance with this section and Agent may if it chooses, in reliance upon such assumption,
make such Loan available to Borrower. If and to the extent such Lender shall not so make its new Loan available to Agent, such Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Loan
together with interest thereon, for each day from the date such amount was made available to Borrower until the date such amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such Lender is making such payment and (ii)
the interest rate applicable at the time to the other new Loans made on such date, if Borrower is making such repayment. If neither such Lender nor Borrower pay or repay to Agent such amount within such three-day period, Agent shall in addition to
such amount be entitled to recover from such Lender and from Borrower, on demand, interest thereon at the Default Rate, calculated from the date such amount was made available to Borrower. The failure of any Lender to make any new Loan to be made by
it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender. 
  
 Section 2.3. Continuations and Conversions of Existing Loans. Borrower
may make the following elections with respect to Loans already outstanding: to convert ABR Loans to Eurodollar Loans, to convert Eurodollar Loans to ABR Loans on the last day of the Interest Period applicable thereto, or to continue Eurodollar Loans
beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings into one new
Borrowing or divide existing Loans made pursuant to one Borrowing into separate new Borrowings. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such conversion or
continuation of existing Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a “Continuation/Conversion Notice” hereunder and must: 
  
 (a) specify the existing Loans which are to be continued or converted; 
  
 (b) specify (i) the aggregate amount of any Borrowing of ABR
Loans into which such existing Loans are to be continued or converted and the date on which such continuation or conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are to be
continued or converted, the date on which such continuation or conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and 

 
 (c) be received by Agent not later than 12:00 noon, New
York City time, on (i) the day on which any such continuation or conversion to ABR Loans is to occur, or (ii) the third Business Day preceding the day on which any such continuation or conversion to Eurodollar Loans is to occur. 
  

 21 

 Each such written request or confirmation must be made in the form and substance of the “Continuation/Conversion
Notice” attached hereto as Exhibit C, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written
confirmation. Upon receipt of any such Continuation/Conversion Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Borrowing Notice shall be irrevocable and binding on Borrower. During the continuance of any Default,
Borrower may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any notice
of continuation or conversion with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into ABR Loans at the end
of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any continuation or conversion of existing Loans pursuant to this section, and no such continuation or conversion shall be deemed to be a
new advance of funds for any purpose; such continuations and conversions merely constitute a change in the interest rate applicable to already outstanding Loans. 
  
 Section 2.4. Use of Proceeds. Borrower shall use all Loans to refinance indebtedness under the Existing Credit
Agreement, finance capital expenditures, and provide working capital for its operations and for other general business purposes, including the acquisition of oil and gas properties and related assets. In no event shall the funds from any Loan be
used directly or indirectly by any Person (i) for personal, family, household or agricultural purposes or (ii) for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any “margin stock” or any
“margin securities” (as such terms are defined respectively in Regulation U and Regulation G promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of
purchasing or carrying any such margin stock or margin securities or (iii) for the acquisition of any Person unless such acquisition has been approved by the board of directors, management committee or partners, as the case may be of such Person.
Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower’s important activities, in the business of extending credit to others for the purpose of purchasing or carrying such margin stock or margin
securities. 
  
 Section 2.5. Fees. 
  
 (a) Commitment Fees. In consideration of each
Lender’s commitment to make Loans, Borrower will pay to Agent for the account of each Lender a commitment fee determined on a daily basis by applying the Commitment Fee Rate to such Lender’s Percentage Share of the unused portion of the
Borrowing Base on each day during the Commitment Period, determined for each such day by deducting from the amount of the Borrowing Base at the end of such day the Facility Usage. This commitment fee will be due and payable in arrears on each ABR
Payment Date and at the end of the Commitment Period. 
  
 (b) Other Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay fees to Agent as described in a letter agreement of March 15, 2005 between Agent and Borrower. 
  

 22 

 (c) Letter of Credit Stated Amount Fee. The Borrower agrees to pay to the Agent,
for the account of each Lender, a participation fee with respect to its participations in Letters of Credit, for the period from and including the date of the issuance of such Letter of Credit to (but not including) the date upon which such Letter
of Credit expires, at a rate per annum equal to Eurodollar Margin on the Stated Amount of such Letter of Credit, based on a year comprised of three-hundred and sixty (360) days (such participation fee, “Letter of Credit Fee”). A
prorated portion of such fee shall be payable by the Borrower in arrears on each ABR Payment Date, and at the end of the Commitment Period for any period then ending for which such fee shall not theretofore have been paid, commencing on the first
such date after the issuance of such Letter of Credit. 
  
 (d) Letter of Credit Issuance Fee. The Borrower agrees to pay to each Issuer for its own account an issuance fee for each Letter of Credit issued by such Issuer equal to 0.125% of the Stated Amount of such Letter of Credit. Such fee
shall be payable by the Borrower on the date of issuance of such Letter of Credit. The Borrower also agrees to pay such Issuer’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing
of drawings thereunder, which fees shall be payable to such Issuer within ten (10) days after demand. 
  
 (e) Upfront Fee. In the event that, as a result of a redetermination of the Borrowing Base, the Borrowing Base is increased to an
amount that is higher than $230,000,000 (the “Base Amount”; and such higher amount herein the “Designated Amount”), the Borrower agrees to pay to the Agent, for the account of each Lender, an upfront fee in an amount equal to 30
basis points on such Lender’s Percentage of the difference between the Designated Amount and the Base Amount; provided, however, that solely for purposes of calculating the upfront fee pursuant to this clause (e), upon payment of such upfront
fee and for purposes of future upfront fees pursuant to this clause (e), the Base Amount shall be increased to be equal to the last Designated Amount for which an upfront fee has been paid hereunder. 
  
 Section 2.6. Optional Prepayments. Borrower may, upon one Business
Day’s notice in the case of ABR Loans, or three Business Days’ notice in the case of Eurodollar Loans, to Agent for the account of each Lender, from time to time and without premium or penalty prepay the Notes, in whole or in part, so long
as the aggregate amounts of all partial prepayments of principal on the Notes equals $500,000 or any higher integral multiple of $100,000, so long as Borrower pays all breakage costs associated with the prepayment of any Eurodollar Loan as provided
in Section 3.5, and so long as Borrower does not make any prepayments which would reduce the unpaid principal balance of any Loan to less than $100,000 without first either (a) terminating this Agreement or (b) providing assurance satisfactory to
Agent in its discretion that Lenders’ legal rights under the Loan Documents are in no way affected by such reduction. Each prepayment of principal of a Eurodollar Loan under this section shall be accompanied by all interest then accrued and
unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

  

 23 

	Section	2.7. Mandatory Prepayments. 

  
 (a) If at any time the Facility Usage exceeds the Commitment (whether due to a reduction in the Commitment in accordance with this
Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Loans (and, upon repayment of all Loans, shall provide cash collateral as set forth in Section 2.11(g)) in an amount at least equal to such excess.

  
 (b) If at any time the Facility Usage is less
than the Commitment but in excess of the Borrowing Base (such excess being herein called a “Borrowing Base Deficiency”), Borrower shall, within five Business Days after Agent gives notice of such fact to Borrower, either: 
  
 (i) prepay the principal of the Loans (and, upon repayment
in full of all Loans, shall provide cash collateral to Issuer as set forth in Section 2.11(g)) in an aggregate amount at least equal to such Borrowing Base Deficiency, or 
  
 (ii) give notice to Agent electing to prepay the principal of the Loans (and, upon repayment of all Loans,
shall provide cash collateral as set forth in Section 2.11(g)) in up to three monthly installments in an aggregate amount at least equal to such Borrowing Base Deficiency, with each such installment equal to or in excess of one-third of such
Borrowing Base Deficiency, and with the first such installment to be paid one month after the giving of such notice and the subsequent installments to be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been
eliminated, or 
  
 (iii) give notice to Agent
that Borrower desires to provide Agent with deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other security documents in form and substance satisfactory to Agent, granting, confirming, and perfecting first
and prior liens or security interests in collateral acceptable to Required Lenders, to the extent needed to allow Required Lenders to increase the Borrowing Base (as they in their reasonable discretion deem consistent with prudent oil and gas
banking industry lending standards at the time) to an amount which eliminates such Borrowing Base Deficiency, and then provide such security documents within thirty days after Agent specifies such collateral to Borrower. If, prior to any such
specification by Agent, Required Lenders determine that the giving of such security documents will not serve to eliminate such Borrowing Base Deficiency, then, within five Business Days after receiving notice of such determination, Borrower will
elect to make, and thereafter make, the prepayments specified in either of the preceding subsections (i) or (ii) of this subsection (b). 
  
 (c) The Borrower will prepay the Loans (and/or provide cash collateral) to the extent otherwise required by the other provisions of this
Agreement. 
  
 (d) Each prepayment of principal
of a Eurodollar Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu 

  

 24 

 
of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. 
  
 Section 2.8. Initial Borrowing Base. During the period from the date
hereof to the first Determination Date, the Borrowing Base shall be $230,000,000. 
  
 Section 2.9. Subsequent Determinations of Borrowing Base. 
  
 By each Evaluation Date (or in the case of an Evaluation Date pursuant to clause (a) of the definition of “Evaluation Date”, within thirty days
after such Evaluation Date), Borrower shall furnish to each Lender all information, reports and data which Agent has then requested concerning Restricted Persons’ businesses and properties (including their oil and gas properties and interests
and the reserves and production relating thereto), together with the Engineering Report described in Section 6.2 which is then due, if any; provided that in the case of any “Evaluation Date” pursuant to clause (a) of the definition
thereof, Borrower shall deliver to Agent an Engineering Report of the type described in Section 6.2(e) within thirty days after such Evaluation Date. Within thirty days after receiving such information, reports and data, Required Lenders shall agree
upon an amount for the Borrowing Base, and Agent shall by notice to Borrower designate such amount as the new Borrowing Base available to Borrower hereunder, which designation shall take effect immediately on the date such notice is sent (herein
called a “Determination Date”) and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined. If Borrower does not furnish all such information, reports and data by the date specified in
the first sentence of this section, Agent may nonetheless designate the Borrowing Base at any amount which Required Lenders determine and may redesignate the Borrowing Base from time to time thereafter until each Lender receives all such
information, reports and data, whereupon Required Lenders shall designate a new Borrowing Base as described above. Required Lenders shall determine the amount of the Borrowing Base based upon the loan collateral value which they in their discretion
assign to the various oil and gas properties included in the Collateral at the time in question and based upon such other credit factors (including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign
exchange rate, and interest rate changes, business, properties, prospects, management and ownership of Borrower and its Affiliates) as they in their discretion deem significant. It is expressly understood that Lenders and Agent have no obligation to
agree upon or designate the Borrowing Base at any particular amount, whether in relation to the Commitment or otherwise, and that Lenders’ commitments to advance funds hereunder is determined by reference to the Borrowing Base from time to time
in effect, which Borrowing Base shall be used to the extent permitted by Law and regulatory authorities, for the purposes of capital adequacy determination and reimbursements under Section 3.2. Should the last day for Lenders to redetermine the
Borrowing Base in connection with a particular Evaluation Date be a day other than a Business Day, the period for such redetermination shall be extended to the next succeeding Business Day. 
  
 Section 2.10. Maturity Date and Requests for Extension. The Loans
shall be finally due and payable on the Maturity Date, subject to earlier maturity in accordance with the terms hereof; provided, that, so long as no Default or Event of Default is existing, the Maturity Date may be extended at the written
request of the Borrower for an additional one-year period upon the written approval of each Lender, which shall be determined in each Lender’s sole discretion. 

  

 25 

 
Unless the Agent shall have received from the Borrower a written request regarding the extension of the Maturity Date at least sixty (60) days prior to the
Maturity Date then in effect, the Lenders will not consider extending and will not extend the Maturity Date. If the Agent has received such a request for extension by such time, the Agent will notify the Borrower whether or not Lenders will extend
the Maturity Date in writing at least thirty (30) days prior to the Maturity Date then in effect. 
  
 Section 2.11. Letters of Credit. From time to time on any Business Day prior to the end of the Commitment Period, each Issuer will issue, and each
Lender will participate in, to the extent of each Lender’s Percentage Share, the Letters of Credit, in accordance with the following terms: 
  
 (a) Issuance Requests. By delivering to the Agent and the applicable Issuer an Issuance Request on or before 11:00 a.m., Central
time, the Borrower may request, from time to time during the Commitment Period and on not less than three (3) nor more than ten (10) Business Days’ notice, that such Issuer issue an irrevocable standby letter of credit in such form as may be
mutually agreed to by the Borrower and such Issuer (each a “Letter of Credit”), in support of financial obligations of the Borrower incurred in the Borrower’s ordinary course of business and which are described in such Issuance
Request. Upon receipt of an Issuance Request, the Agent shall promptly notify the Lenders thereof. Each Letter of Credit shall by its terms: (i) be issued in a Stated Amount which (1) together with all Letter of Credit Outstandings and all
outstanding Loans does not exceed (or would not exceed) the then Commitment or Borrowing Base or (2) together with all Letter of Credit Outstandings would not exceed $90,000,000; (ii) be stated to expire on a date (its “Stated Expiry
Date”) no later than the earlier (1) of one year from its date of issuance and (2) the end of the Commitment Period. So long as no Default has occurred and is continuing, by delivery to the applicable Issuer and the Agent of an Issuance Request
at least three (3) but not more than ten (10) Business Days prior to the Stated Expiry Date of any Letter of Credit, the Borrower may request such Issuer to extend the Stated Expiry Date of such Letter of Credit for an additional period not to
exceed the earlier of (i) one year from its date of extension or (ii) the end of the Commitment Period. 
  
 No Issuer is under any obligation to issue any Letter of Credit if: (i) any order, judgment or decree of any government agency or
arbitrator shall by its terms purport to enjoin or restrain such Issuer from issuing such Letter of Credit, or any requirement of applicable Law or any request or directive (whether or not having the force of law) from any government agency with
jurisdiction over such Issuer shall prohibit, or request that the Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuer with respect to such Letter of Credit any
restriction, reserve or capital requirement (for which such Issuer is not otherwise compensated hereunder) not in effect on the date hereof, or shall impose upon such Issuer any unreimbursed loss, cost or expense which was not applicable on the date
hereof and which such Issuer in good faith deems material to it; (ii) one or more of the applicable conditions contained in Article IV is not then satisfied; (iii) the expiry date of any requested Letter of Credit is prior to the maturity date of
any financial obligation to be supported by the requested Letter of Credit; (iv) any requested Letter of Credit does not 

  

 26 

 
provide for drafts, or is not otherwise in form and substance acceptable to such Issuer, or the issuance of a Letter of Credit shall violate any applicable
policies of such Issuer; (v) any standby Letter of Credit is for the purpose of supporting the issuance of any letter of credit by any other Person; or (vi) such Letter of Credit is in a face amount denominated in a currency other than Dollars. The
Uniform Customs and Practice for Documentary Credits most recently published by the International Chamber of Commerce at the time of issuance of any Letter of Credit shall (unless otherwise expressly provided in the Letter of Credit) apply to all
Letters of Credit. 
  
 (b) Issuances and
Extensions. On the terms and subject to the conditions of this Agreement (including Article IV), the applicable Issuer shall issue Letters of Credit, and extend the Stated Expiry Dates of outstanding Letters of Credit, in accordance with
the Issuance Requests made therefor. Each Issuer will make available the original of each Letter of Credit which it issues in accordance with the Issuance Request therefor to the beneficiary thereof (and will promptly provide each of the Lenders and
the Borrower with a copy of such Letter of Credit) and will notify the beneficiary under any Letter of Credit of any extension of the Stated Expiry Date thereof. 
  
 (c) Existing Letter of Credit. The parties acknowledge and agree that the letter of credit issued by
The Toronto Dominion Bank under the Existing Credit Agreement in the face amount of $5,000,000 naming Greenwich Insurance Company as beneficiary thereunder shall be deemed to be a Letter of Credit issued hereunder by The Toronto Dominion Bank having
the same face amount, maturity date and general terms. 
  
 (d) Other Lenders’ Participation. Each Letter of Credit issued pursuant to Section 2.11(b) shall, effective upon its issuance and without further action, be issued on behalf of all Lenders (including the
Issuer thereof) pro rata according to their respective Percentage Shares. Each Lender shall, to the extent of its Percentage Share, be deemed irrevocably to have participated in the issuance of such Letter of Credit and shall be responsible to
reimburse promptly the Issuer thereof for Reimbursement Obligations which have not been reimbursed by the Borrower in accordance with Section 2.11(e), or which have been reimbursed by the Borrower but must be returned, restored or disgorged by such
Issuer for any reason, and each Lender shall, to the extent of its Percentage Share, be entitled to receive from the Agent a ratable portion of the Letter of Credit Fee received by the Agent pursuant to Section 2.5(c), with respect to each Letter of
Credit. In the event that the Borrower shall fail to reimburse any Issuer, or if for any reason Loans shall not be made to fund any Reimbursement Obligation, all as provided in Section 2.11(e) and in an amount equal to the amount of any drawing
honored by such Issuer under a Letter of Credit issued by it, or in the event such Issuer must for any reason return or disgorge such reimbursement, such Issuer shall promptly notify each Lender of the unreimbursed amount of such drawing and of such
Lender’s respective participation therein. Each Lender shall make available to such Issuer, whether or not any Default shall have occurred and be continuing, an amount equal to its respective participation in same day or immediately available
funds at the office of such Issuer specified in such notice not later than 11:00 a.m., Central time, on the Business Day (under the laws of the jurisdiction of such Issuer) after the date notified by such Issuer. In the event that any Lender fails
to make available to such Issuer the amount of such Lender’s participation in 

  

 27 

 
such Letter of Credit as provided herein, such Issuer shall be entitled to recover such amount on demand from such Lender together with interest at the daily
average Federal Funds Rate for three (3) Business Days (together with such other compensatory amounts as may be required to be paid by such Lender to the Agent pursuant to the Rules for Interbank Compensation of the council on International Banking
or the Clearinghouse Compensation Committee, as the case may be, as in effect from time to time) and thereafter at the interest rate applicable to ABR Loans plus two percent (2%). Nothing in this Section shall be deemed to prejudice the right of any
Lender to recover from any Issuer any amounts made available by such Lender to such Issuer pursuant to this Section in the event that it is determined by a court of competent jurisdiction that the payment with respect to a Letter of Credit by such
Issuer in respect of which payment was made by such Lender constituted gross negligence or willful misconduct on the part of such Issuer. Each Issuer shall distribute to each other Lender which has paid all amounts payable by it under this Section
with respect to any Letter of Credit issued by such Issuer such other Lender’s Percentage Share of all payments received by such Issuer from the Borrower in reimbursement of drawings honored by such Issuer under such Letter of Credit when such
payments are received. 
  
 (e)
Disbursements. Each Issuer will notify the Borrower and the Agent promptly of the presentment for payment of any Letter of Credit, together with notice of the date (the “Disbursement Date”) such payment shall be made. Subject to the
terms and provisions of such Letter of Credit, the applicable Issuer shall make such payment to the beneficiary (or its designee) of such Letter of Credit. Prior to 11:00 a.m., Central time, on the Disbursement Date, the Borrower will reimburse the
applicable Issuer for all amounts which it has disbursed under or in respect of such Letter of Credit. In the event the applicable Issuer is not reimbursed by the Borrower on the Disbursement Date, or if such Issuer must for any reason return or
disgorge such reimbursement, the Lenders (including such Issuer) shall, on the terms and subject to the conditions of this Agreement, fund the Reimbursement Obligation therefor by making, on the next Business Day, Loans which are ABR Loans as
provided in Section 2.1 (the Borrower being deemed to have given a timely Borrowing Notice therefor for such amount); provided, however, for the purpose of determining the availability of the Commitments to make Loans immediately prior
to giving effect to the application of the proceeds of such Loans, such Reimbursement Obligation shall be deemed not to be outstanding at such time. To the extent the applicable Issuer is not reimbursed in full in accordance with the preceding
sentences, the Borrower’s Reimbursement Obligation shall accrue interest at a fluctuating rate determined by reference to the interest rate applicable to ABR Loans, plus a margin of two percent (2%) per annum, payable on demand. 
  
 (f) Reimbursement. The Borrower’s obligation (a
“Reimbursement Obligation”) under Section 2.11(e) to reimburse an Issuer with respect to each Disbursement (including interest thereon), and each Lender’s obligation to make participation payments in each drawing which has not been
reimbursed by the Borrower, shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim, or defense to payment which the Borrower may have or have had against any Lender or any beneficiary of a
Letter of Credit, including any defense based upon the occurrence of any Default, any draft, demand or certificate or other 

  

 28 

 
document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient, the failure of any disbursement to conform to the
terms of the applicable Letter of Credit (if, in the applicable Issuer’s good faith opinion, such disbursement is determined to be appropriate) or any non-application or misapplication by the beneficiary of the proceeds of such disbursement, or
the legality, validity, form, regularity, or enforceability of such Letter of Credit; provided, however, that nothing herein shall adversely affect the right of the Borrower or any Lender to commence any proceeding against the
applicable Issuer for any wrongful disbursement made by such Issuer under a Letter of Credit as a result of acts or omissions constituting gross negligence or willful misconduct on the part of such Issuer. 
  
 (g) Deemed Disbursements. Upon either (i) the
occurrence and during the continuation of an Event of Default pursuant to Section 8.1(j) or the occurrence of the end of the Commitment Period or (ii) the declaration by the Agent of all or any portion of the outstanding principal amount of the
Loans and other Obligations to be due and payable and/or the commitments (if not theretofore terminated) to be terminated as provided in Section 8.1, an amount equal to that portion of Letter of Credit Outstandings attributable to outstanding and
undrawn Letters of Credit shall, at the election of the applicable Issuer acting on instructions from the Required Lenders, and without demand upon or notice to the Borrower, be deemed to have been paid or disbursed by such Issuer under such Letters
of Credit (notwithstanding that such amount may not in fact have been so paid or disbursed), and, upon notification by such Issuer to the Agent and the Borrower of its obligations under this Section, the Borrower shall be immediately obligated to
reimburse such Issuer the amount deemed to have been so paid or disbursed by such Issuer. Any amounts so received by such Issuer from the Borrower pursuant to this Section shall be held as collateral security for the repayment of the Borrower’s
obligations in connection with the Letters of Credit issued by such Issuer. All amounts on deposit pursuant to this Section 2.11(g) shall, until their application to any Obligation or their return to the Borrower, as the case may be, at the
Borrower’s written request, be invested in high grade short term liquid investments as such Issuer may choose in its sole discretion reasonably exercised, which interest shall be held by the applicable Issuer as additional collateral security
for the repayment of the Borrower’s Obligations under and in connection with the Letters of Credit and all other Obligations. Any losses, net of earnings, and reasonable fees and expenses of such investments shall be charged against the
principal amount invested. No Lender Party shall be liable for any loss resulting from any investment made by such Issuer at the Borrower’s request. Such Issuer is not obligated hereby, or by any other Loan Document, to make or maintain any
investment, except upon written request by the Borrower. At any time when such Letters of Credit shall terminate and all Obligations to each Issuer are either terminated or paid or reimbursed to such Issuer in full, the Obligations of the Borrower
under this Section shall be reduced accordingly (subject, however, to reinstatement in the event any payment in respect of such Letters of Credit is recovered in any manner from such Issuer), and such Issuer will return to the Borrower the excess,
if any, of (A) the aggregate amount held by such Issuer and not theretofore applied by such Issuer to any Reimbursement Obligation over (B) the aggregate amount of all Reimbursement Obligations to such Issuer pursuant to this Section, as so
adjusted. At such time when all Events of Default shall have been cured or waived, if the end of the Commitment Period shall not have occurred for any 

  

 29 

 
reason, each Issuer shall return to the Borrower all amounts then on deposit with such Issuer pursuant to this Section. Borrower hereby assigns and grants to
such Issuer a continuing security interest in all such collateral security paid by it to such Issuer, all investments purchased with such collateral security, and all proceeds thereof to secure its Obligations under this Agreement, the Notes, and
the other Loan Documents, and Borrower agrees that collateral security and investments shall be subject to all of the terms and conditions of the Security Documents. Borrower further agrees that such Issuer shall have all of the rights and remedies
of a secured party under the Uniform Commercial Code as adopted in the State of Texas with respect to such security interest and that an Event of Default under this Agreement shall constitute a default for purposes of such security interest.

  
 (h) Nature of Reimbursement
Obligations. The Borrower shall assume all risks of the acts, omissions, or misuse of any Letter of Credit by the beneficiary thereof. Neither any Issuer nor any Lender (except to the extent of its own gross negligence or willful misconduct)
shall be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness, or legal effect of any Letter of Credit or any document submitted by any party in connection with the application for and issuance of a Letter of Credit, even if
it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent, or forged; (ii) the form, validity, sufficiency, accuracy, genuineness, or legal effect of any instrument transferring or assigning or purporting to
transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) failure of the beneficiary to comply fully with conditions
required in order to demand payment under a Letter of Credit; (iv) errors, omissions, interruptions, or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex, facsimile or otherwise; (v) any loss or delay in the
transmission or otherwise of any document or draft required in order to make a Disbursement under a Letter of Credit or of the proceeds thereof; (vi) any change in the time, manner or place of payment of, or in any other term of, all or any of the
obligations of the Borrower in respect of any Letter of Credit; (vii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or any Person
for whom any such beneficiary or any such transferee may be acting), the Issuer (if other than the Lender or its Affiliates) or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by the Letter of
Credit or any unrelated transaction; (viii) any payment by an Issuer under any Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of any Letter of Credit; or any payment made by an Issuer
under any Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of any
Letter of Credit, including any arising in connection with any insolvency proceeding; or (ix) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise
constitute a defense available to, or a discharge of, the Borrower or a guarantor. None of the foregoing shall affect, impair, or prevent the vesting of any of the rights or powers granted any Issuer or any Lender hereunder. In furtherance and
extension, and not in limitation or derogation, of any of the foregoing, any action taken or 

  

 30 

 
omitted to be taken by any Issuer in good faith shall be binding upon the Borrower and shall not put such Issuer under any resulting liability to the
Borrower. 
  
 (i) Increased Costs;
Indemnity. If by reason of (i) any change in applicable law, regulation, rule, decree or regulatory requirement or any change in the interpretation or application by any judicial or regulatory authority of any law, regulation, rule, decree or
regulatory requirement, or (ii) compliance by any Issuer or any Lender with any direction, or requirement of any governmental or monetary authority, including, without limitation, Regulation D: (1) any Issuer or any Lender shall be subject to any
tax (other than taxes on net income and franchises), levy, charge or withholding of any nature or to any variation thereof or to any penalty with respect to the maintenance or fulfillment of its obligations under this Section 2.11, whether directly
or by such being imposed on or suffered by such Issuer or such Lender; (2) any reserve, deposit or similar requirement is or shall be applicable, increased, imposed or modified in respect of any Letters of Credit issued by any Issuer or
participations therein purchased by any Lender; or (3) there shall be imposed on any Issuer or any Lender any other condition regarding this Section 2.11, any Letter of Credit or any participation therein, and the result of the foregoing is directly
to increase the cost to such Issuer or such Lender of issuing or maintaining any Letter of Credit or of purchasing or maintaining any participation therein, or to reduce any amount receivable in respect thereof by such Issuer or such Lender, then
and in any such case such Issuer or such Lender may, at any time after the additional cost is incurred or the amount received is reduced, notify the Agent and the Borrower thereof, and the Borrower shall pay within ten (10) days of demand such
amounts as such Issuer or Lender may in good faith specify to be necessary to compensate such Issuer or Lender for such additional cost or reduced receipt, together with interest on such amount from the date demanded until payment in full thereof at
a rate equal at all times to the Alternate Base Rate per annum. The determination by such Issuer or Lender, as the case may be, of any amount due pursuant to this Section, as set forth in a statement setting forth the calculation thereof in
reasonable detail, shall be rebuttable presumptive evidence of such amounts. 
  
 In addition to amounts payable as elsewhere provided in this Section 2.11, the Borrower hereby indemnifies, exonerates and holds each Issuer, the Agent and each Lender harmless from and against any and all actions,
causes of action, suits, losses, costs, liabilities and damages, and expenses incurred in connection therewith (irrespective of whether such Issuer, the Agent or such Lender is a party to the action for which indemnification is sought), including
reasonable attorneys’ fees and disbursements, which such Issuer, the Agent or such Lender may incur or be subject to as a consequence, direct or indirect, of the issuance of the Letters of Credit, other than as a result of the gross negligence
or willful misconduct of such Issuer as determined by a court of competent jurisdiction, or the failure of such Issuer to honor a drawing under any Letter of Credit as a result of any act or omission, whether rightful or wrongful, of any present or
future de jure or de facto government or governmental authority. 
  

 31 

 ARTICLE III - Payments to Lenders 
  
 Section 3.1. General Procedures. Borrower will make each payment which it owes under the Loan Documents to Agent for
the account of the Lender Party to whom such payment is owed. Each such payment must be received by Agent not later than 12:00 noon, New York City time, on the date such payment becomes due and payable, in lawful money of the United States of
America, without set-off, deduction or counterclaim, and in immediately available funds. Any payment received by Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and
payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the
period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place provided therein and, if no specific place of payment is provided, shall be due and
payable at the place of payment of Agent’s Note. When Agent collects or receives money on account of the Obligations, Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as
follows: 
  
 (a) first, for the payment of all
fees and expenses of Agent and its counsel which are then due; 
  
 (b) then for the payment of all other Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Agent under Section 6.9 or 10.4 and second to the
partial payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree); 
  
 (c) then for the prepayment of amounts owing under the Loan Documents (other than principal on the Notes) if so specified by Borrower;

  
 (d) then for the prepayment of principal on
the Notes, together with accrued and unpaid interest on the principal so prepaid; and 
  
 (e) last, for the payment or prepayment of any other Obligations. 
  
 All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal
then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts described in any of subsections (c), (d) or (e) above shall be made by Agent pro rata to each Lender
Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection. 
  
 Section 3.2. Capital Reimbursement. If either (a) the introduction or implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the compliance with any request, directive or guideline from any central bank or other governmental authority (whether or not having the force of Law) affects or would affect
the amount of capital required or expected to be maintained by any Lender Party (or any assignee of such Lender Party) or any corporation controlling any Lender 

  

 32 

 
Party (or its assignee), then, upon demand by such Lender Party, Borrower will pay to Agent for the benefit of such Lender Party, from time to time as
specified by such Lender Party, such additional amount or amounts which such Lender Party shall reasonably determine to be appropriate to compensate such Lender Party or any corporation controlling such Lender Party in light of such circumstances,
to the extent that such Lender Party reasonably determines that the amount of any such capital would be increased or the rate of return on any such capital would be reduced by or in whole or in part based on the existence of the face amount of such
Lender Party’s Loans or commitments under this Agreement. 
  
 Section 3.3. Increased Cost of Eurodollar Loans. If any applicable Law (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental
authority charged with the interpretation or administration thereof (whether or not having the force of Law): 
  
 (a) shall change the basis of taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any
Eurodollar Loan or otherwise due under this Agreement in respect of any Eurodollar Loan (other than taxes imposed on the overall net income of such Lender Party or any lending office of such Lender Party by any jurisdiction in which such Lender
Party or any such lending office is located); or 
  
 (b) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Loan (excluding those for which such Lender Party is fully compensated pursuant to adjustments made
in the definition of Eurodollar Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender Party; or 
  
 (c) shall impose on any Lender Party or the interbank eurocurrency deposit market any other condition affecting any Eurodollar Loan, the
result of which is to increase the cost to any Lender Party of funding or maintaining any Eurodollar Loan or to reduce the amount of any sum receivable by any Lender Party in respect of any Eurodollar Loan by an amount deemed by such Lender Party to
be material, 
  
 then such Lender Party shall promptly notify Agent and Borrower
in writing of the happening of such event and of the amount required to compensate such Lender Party for such event (on an after-tax basis, taking into account any taxes on such compensation), whereupon (i) Borrower shall pay such amount to Agent
for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loans into ABR Loans.

  
 Section 3.4. Availability. If (a) any change in
applicable Laws, or in the interpretation or administration thereof of or in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful or impracticable for any Lender Party to fund or maintain Eurodollar Loans (or to participate in,
issue or maintain any Letter of Credit), or shall materially restrict the authority of any Lender Party to purchase or take offshore deposits of dollars (i.e., “eurodollars”), or (b) any Lender Party determines that matching deposits
appropriate to fund or maintain any Eurodollar Loan (or to participate in, issue or maintain any Letter of Credit) are not available to it, or (c) any Lender Party determines that the formula for calculating the Adjusted Eurodollar Rate does not

  

 33 

 
fairly reflect the cost to such Lender Party of making or maintaining Loans (or of participating in, issuing or maintaining any Letter of Credit) based on
such rate, then, upon notice by such Lender Party to Borrower and Agent, Borrower’s right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, impracticability or restriction
and all Eurodollar Loans (or participations in, issuances of or maintenance of any Letter of Credit) of such Lender Party which are then outstanding or are then the subject of any Borrowing Notice (or Issuance Request) and which cannot lawfully or
practicably be maintained or funded shall immediately become or remain, or shall be funded as, ABR Loans of such Lender Party. Borrower agrees to indemnify each Lender Party and hold it harmless against all costs, expenses, claims, penalties,
liabilities and damages which may result from any such change in Law, interpretation or administration. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. 
  
 Section 3.5. Funding, Losses. In addition to its other obligations
hereunder, Borrower will indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by a Lender Party to fund or maintain Eurodollar Loans), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan
on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice,
if such payment or prepayment prevents such Continuation/Conversion Notice from becoming fully effective, (c) the failure of any Loan to be made or of any Continuation/Conversion Notice to become effective due to any condition precedent not being
satisfied or due to any other action or inaction of any Restricted Person, or (d) any conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Loan into an ABR Loan or into a different Eurodollar
Loan on a day other than the day on which the applicable Interest Period ends. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. 
  
 Section 3.6. Reimbursable Taxes. Borrower covenants and agrees that:

  
 (a) Borrower will indemnify each Lender Party
against and reimburse each Lender Party for all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of this Agreement or any Eurodollar Loans (whether or not
legally or correctly imposed, assessed, levied or collected), excluding, however, any taxes imposed on or measured by the overall net income of Agent or such Lender Party or any lending office of such Lender Party by any jurisdiction in which such
Lender Party or any such lending office is located (all such non-excluded taxes, levies, costs and charges being collectively called “Reimbursable Taxes” in this section). Such indemnification shall be on an after-tax basis, taking into
account any taxes imposed on the amounts paid as indemnity. 
  
 (b) All payments on account of the principal of, and interest on, each Lender Party’s Loans and Note and all payments in respect of any Reimbursement Obligation, and all other amounts payable by Borrower to any
Lender Party hereunder, shall be made 

  

 34 

 
in full without set-off or counterclaim and shall be made free and clear of and without deductions or withholdings of any nature by reason of any
Reimbursable Taxes, all of which will be for the account of Borrower. In the event of Borrower being compelled by Law to make any such deduction or withholding from any payment to any Lender Party, Borrower shall pay on the due date of such payment,
by way of additional interest, such additional amounts as are needed to cause the amount receivable by such Lender Party after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or
withholding. If Borrower should make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to such Lender Party an official receipt or other official document evidencing payment of such deduction or withholding.

  
 (c) If Borrower is ever required to pay any
Reimbursable Tax with respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loan into an ABR Loan,
but such election shall not diminish Borrower’s obligation to pay all Reimbursable Taxes. 
  
 (d) Notwithstanding the foregoing provisions of this section, Borrower shall be entitled, to the extent it is required to do so by Law, to
deduct or withhold (and not to make any indemnification or reimbursement for) income or other similar taxes imposed by the United States of America (other than any portion thereof attributable to a change in federal income tax Laws effected after
the date hereof) from interest, fees or other amounts payable hereunder for the account of any Lender Party, other than a Lender Party (i) who is a U.S. person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Agent
(with copies provided to Borrower) for the applicable year to the extent deduction or withholding of such taxes is not required as a result of the filing of such Prescribed Forms, provided that if Borrower shall so deduct or withhold any such taxes,
it shall provide a statement to Agent and such Lender Party, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender Party may reasonably request for assisting
such Lender Party to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender Party is subject to tax. As used in this section, “Prescribed Forms” means such
duly executed forms or statements, and in such number of copies, which may, from time to time, be prescribed by Law and which, pursuant to applicable provisions of (x) an income tax treaty between the United States and the country of residence of
the Lender Party providing the forms or statements, (y) the Internal Revenue Code of 1986, as amended from time to time, or (z) any applicable rules or regulations thereunder, permit Borrower to make payments hereunder for the account of such Lender
Party free of such deduction or withholding of income or similar taxes. 
  
 Section 3.7. Change of Applicable Lending Office. Each Lender Party agrees that, upon the occurrence of any event giving rise to the operation of any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 with respect to such Lender Party, it will,
if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender Party) to designate another Lending Office, provided that such designation is made on such terms that such Lender Party and its 

  

 35 

 
Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of
any such section. Nothing in this section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6. 
  
 Section 3.8. Replacement of Lenders. If any Lender Party seeks
reimbursement for increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, then within ninety days thereafter and provided no Event of Default then exists, Borrower shall have the right (unless such Lender Party withdraws its request for
additional compensation) to replace such Lender Party by requiring such Lender Party to assign its Loans, Notes and its commitments hereunder to an Eligible Transferee reasonably acceptable to Agent and to Borrower, provided that: (i) all
Obligations of Borrower owing to such Lender Party being replaced (including such increased costs, but excluding principal and accrued interest on the Notes being assigned) shall be paid in full to such Lender Party concurrently with such
assignment, and (ii) the replacement Eligible Transferee shall purchase the Note being assigned by paying to such Lender Party a price equal to the principal amount thereof plus accrued and unpaid interest thereon. In connection with any such
assignment Borrower, Agent, such Lender Party and the replacement Eligible Transferee shall otherwise comply with Section 10.6. Notwithstanding the foregoing rights of Borrower under this section, however, Borrower may not replace any Lender Party
which seeks reimbursement for increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, unless Borrower is at the same time replacing all Lender Parties which are then seeking such compensation. In connection with any such replacement of a
Lender Party, Borrower shall pay all costs that would have been due to such Lender Party pursuant to Section 3.5 if such Lender Party’s Loans had been prepaid at the time of such replacement. 
  
 Section 3.9. Participants. If a Lender has assigned a participation in
its Loans or commitment hereunder to another Person in accordance with Section 10.6, any amount otherwise payable by Borrower to such Lender under Section 3.3 through 3.6 (in this section called “Increased Costs”), shall include that
portion of the Increased Costs determined by such Lender to be allocable to the amount of any interest or participation transferred by such Lender in such Lender’s Loan or commitments under this Agreement.

hereby. Each Restricted Person is duly qualified, in good standing, and authorized to do business in all other jurisdictions within the United States wherein the character of the properties owned or held by it or the nature of the business
transacted by it makes such qualification necessary. Each Restricted Person has taken all actions and procedures customarily taken in order to enter, for the purpose of conducting business or owning property, each jurisdiction outside the United
States wherein the character of the properties owned or held by it or the nature of the business transacted by it makes such actions and procedures desirable.

misleading as of the date made or deemed made. There is no fact known to any Restricted Person (other than industry-wide risks normally associated with the types of businesses conducted by Restricted Persons) that has not been disclosed to each
Lender Party in writing which could cause a Material Adverse Change. There are no statements or conclusions in any Engineering Report which are based upon or include misleading information or fail to take into account material information regarding
the matters reported therein, it being understood that each Engineering Report is necessarily based upon professional opinions, estimates and projections and that Borrower does not warrant that such opinions, estimates and projections will

expressly waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement. Upon any such acceleration, any obligation of any Lender to make any further Loans hereunder and any obligation of any Issuer to issue
Letters of Credit hereunder shall be permanently terminated. During the continuance of any other Event of Default, Agent at any time and from time to time may (and upon written instructions from Required Lenders, Agent shall), without notice to

Obligations immediately due and payable, and all such Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to

 Section 8.2. Remedies. If any Default shall occur and be continuing,
each Lender Party may protect and enforce its rights under the Loan Documents by any appropriate 

  

 58 

 
proceedings, including proceedings for specific performance of any covenant or agreement contained in any Loan Document, and each Lender Party may enforce
the payment of any Obligations due it or enforce any other legal or equitable right which it may have. All rights, remedies and powers conferred upon Lender Parties under the Loan Documents shall be deemed cumulative and not exclusive of any other
rights, remedies or powers available under the Loan Documents or at Law or in equity. 
  
 ARTICLE IX - Agent 
  
 Section 9.1. Appointment and Authority. Each Lender Party hereby irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments of principal, interest and other amounts due hereunder as specified herein and to take
all other actions and to exercise such powers under the Loan Documents as are specifically delegated to Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. The relationship of Agent to the other Lender
Parties is only that of one commercial lender acting as administrative agent for others, and nothing in the Loan Documents shall be construed to constitute Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation
therein nor to impose on Agent duties and obligations other than those expressly provided for in the Loan Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within
the discretion of Agent, Agent shall not be required to exercise any discretion or take any action, and it may request instructions from Lenders with respect to any such matter, in which case it shall be required to act or to refrain from acting
(and shall be fully protected and free from liability to all Lenders in so acting or refraining from acting) upon the instructions of Required Lenders (including itself), provided, however, that Agent shall not be required to take any action which
exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable Law. Upon receipt by Agent from Borrower of any communication calling for action on the part of Lenders or upon
notice from any other Lender Party to Agent of any Default or Event of Default, Agent shall promptly notify each other Lender Party thereof. 
  
 Section 9.2. Exculpation, Agent’s Reliance, Etc. Neither Agent nor any of its directors, officers, agents, attorneys, or employees shall be
liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each shall be liable for its own gross negligence or willful misconduct.
Without limiting the generality of the foregoing, Agent (a) may treat the payee of any Note as the holder thereof until Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and
in form satisfactory to Agent; (b) may consult with legal counsel (including counsel for 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 other Lender Party and shall not be responsible to any other Lender Party for any statements, warranties or representations made
in or in connection with the Loan 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 the Loan Documents on the part of any Restricted Person or to
inspect the property (including the books and records) of any Restricted Person; (e) shall not be 

  

 59 

 
responsible to any other Lender Party for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or
any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of each Restricted Person and the Lenders in exercising its powers hereunder; and (g) shall incur no liability under or in respect of
the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. 
  
 Section 9.3. Credit Decisions. Each Lender Party acknowledges that it
has, independently and without reliance upon any other Lender Party, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender
Party also acknowledges that it will, independently and without reliance upon any other Lender Party 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 the Loan Documents. 
  
 Section 9.4.
Indemnification. Each Lender agrees to indemnify Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender’s Percentage Share of any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called
“liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and
the transactions and events (including the enforcement thereof) at any time associated therewith or contemplated therein (including any Environmental Claims or violation or noncompliance with any Environmental Laws by any Person or any liabilities
or duties of any Person with respect to the presence or Release of Hazardous Materials found in or released into the environment). 
  
 THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR
THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT, 
  
 provided only that no Lender shall be obligated under this section to indemnify Agent for that portion, if any, of any liabilities and costs which is proximately
caused by Agent’s own individual gross negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Lender agrees to reimburse Agent promptly upon demand for such Lender’s Percentage Share of
any costs and expenses to be paid to Agent by Borrower under Section 10.4(a) to the extent that Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this section the term “Agent” shall refer
not only to the Person designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Person. 
  
 Section 9.5. Rights as Lender. In its capacity as a Lender, Agent shall have the same rights and obligations as any
Lender and may exercise such rights as though it were not Agent. 

  

 60 

 
Agent may accept deposits from, lend money to, act as Trustee under indentures of, and generally engage in any kind of business with any Restricted Person or
their Affiliates, all as if it were not Agent hereunder and without any duty to account therefor to any other Lender. 
  
 Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights under
Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Agent under Section
3.1, causes such Lender Party to have received more than it would have received had such payment been received by Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to
purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Agent and all
Lenders share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker’s lien,
set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not
acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such
interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to
have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to Tribunal order to be paid on account of the possession of such funds prior to such recovery. 
  
 Section 9.7. Investments. Whenever Agent in good faith determines that
it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Agent in good faith determines that there is any dispute among Lenders about how such funds should be distributed, Agent may choose to defer distribution
of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to Lenders,
Agent shall invest such funds pending distribution; all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Agent
for distribution to Lenders (other than to the Person who is Agent in its separate capacity as a Lender) shall be held by Agent pending such distribution solely as Agent for such Lenders, and Agent shall have no equitable title to any portion
thereof. 
  
 Section 9.8. Benefit of Article IX. The
provisions of this Article (other than the following Section 9.9) are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense
against any Lender Party. Lender Parties may waive or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person. 
  

 61 

 Section 9.9. Resignation. Agent may resign at any time by giving written notice thereof to Lenders
and Borrower. Each such notice shall set forth the date of such resignation. Required Lenders shall have the right to appoint a successor Agent. A successor must be appointed for any retiring Agent, and such Agent’s resignation shall become
effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Agent’s resignation, no successor Agent has been appointed and has accepted such appointment, then the retiring Agent may appoint a
successor Agent, which shall be a financial institution organized under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, the retiring Agent shall be
discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent’s resignation hereunder the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under the Loan Documents. 
  
 ARTICLE X - Miscellaneous 
  
 Section 10.1.
Waivers and Amendments; Acknowledgments. 
  
 (a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender Party in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate
as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No
waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the
specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand
in similar or other circumstances. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and
understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto
unless the same is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if such party is Agent, by such party, (iii) if such party is a Lender, by such Lender or by Agent on behalf of Lenders with the written consent of Required
Lenders (which consent has already been given as to the termination of the Loan Documents as provided in Section 10.14) and (iv) if such party is Issuer, by Issuer. Notwithstanding the foregoing or anything to the contrary herein, Agent shall not,
without the prior consent of each individual Lender, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Article IV (provided that Agent may in its discretion withdraw any
request it has made under Section 4.2(e)), (2) increase the Commitment of such Lender or subject such Lender to any additional obligations, (3) reduce any fees payable to such lender 

  

 62 

 
hereunder, or the principal of, or interest on, such Lender’s Note, (4) postpone any date fixed for any payment of any such fees, principal or interest,
(5) increase the Facility Amount or the aggregate Commitment of the Lenders to an amount in either case in excess of $300,000,000 or amend the definition herein of “Required Lenders” or otherwise change the aggregate amount of Percentage
Shares which is required for Agent, Lenders or any of them to take any particular action under the Loan Documents, (6) release Borrower from its obligation to pay such Lender’s Note or (7) release all or substantially all of the Collateral.
Notwithstanding the foregoing, to the extent that the Borrower or any Restricted Person transfers, sells or otherwise assigns any Collateral in accordance with the Loan Documents, the Agent is authorized to release the Agent’s and Lenders’
Liens on such Collateral without any further consent by any of the Lenders. 
  
 (b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to
which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Agent or any Lender, whether
written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by any Lender Party
as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender Party has any fiduciary obligation toward Borrower with respect to any Loan Document or the
transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender Party, on the other hand, is and shall be solely that of debtor and creditor,
respectively, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender Party, (vii) Agent is not Borrower’s Agent, but Agent for Lenders, (viii) should an Event of Default or
Default occur or exist, each Lender Party will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (ix) without limiting any of the foregoing, Borrower is not relying
upon any representation or covenant by any Lender Party, or any representative thereof, and no such representation or covenant has been made, that any Lender Party will, at the time of an Event of Default or Default, or at any other time, waive,
negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the
truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become obligated hereunder. 
  
 (c) Representation by Lenders. Each Lender hereby represents that it will acquire its Note for its own account in the ordinary
course of its commercial lending business; however, the disposition of such Lender’s property shall at all times be and remain within its control and, in particular and without limitation, such Lender may sell or otherwise transfer its Note,
any participation interest or other interest in its Note, or any of its other rights and obligations under the Loan Documents. 
  

 63 

 (d) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. 
  
 THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 
  
 Section 10.2. Survival of Agreements; Cumulative Nature. All of
Restricted Persons’ various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including
the making or granting of the Loans and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties’ obligations to Borrower are
terminated. All statements and agreements contained in any certificate or other instrument delivered by any Restricted Person to any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower or agreements and
covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights, powers, and privileges granted to Lender Parties in the Loan Documents, are
cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such representation, warranty,
indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation,
warranty, indemnity, or covenant contained in any other Loan Document, and each such similar representation, warranty, indemnity, or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the
various Loan Documents. 
  
 Section 10.3. Notices. All
notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Agent may give telephonic notices to the
other Lender Parties), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by telecopy or telex, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to
Borrower and Restricted Persons at the address of Borrower specified on the signature pages hereto and to each Lender Party at its address specified in the Lenders Schedule as its lending offices for ABR Loans (unless changed by similar notice in
writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during
normal business hours at the address provided herein, (b) in the case of telecopy or telex, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Borrowing
Notice shall become effective until actually received by Agent. 
  

 64 

 Section 10.4. Payment of Expenses; Indemnity. 
  
 (a) Payment of Expenses. Whether or not the
transactions contemplated by this Agreement are consummated, Borrower will promptly (and in any event, within 30 days after any invoice or other statement or notice) pay: (i) all transfer, stamp, mortgage, documentary or other similar taxes,
assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on
behalf of Agent (including attorneys’ fees, consultants’ fees and engineering fees, travel costs and miscellaneous expenses) in connection with (1) the negotiation, preparation, execution and delivery of the Loan Documents, and any and all
consents, waivers or other documents or instruments relating thereto, (2) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled
or re-recorded by the terms of any Loan Document, (3) the borrowings hereunder and other action reasonably required in the course of administration hereof, (4) monitoring or confirming (or preparation or negotiation of any document related to)
Borrower’s compliance with any covenants or conditions contained in this Agreement or in any Loan Document, and (iii) all reasonable costs and expenses incurred by or on behalf of any Lender Party (including reasonable attorneys’ fees,
consultants’ fees and accounting fees) in connection with the defense or enforcement of any of the Loan Documents (including this section) or the defense of any Lender Party’s exercise of its rights thereunder. In addition to the
foregoing, until all Obligations have been paid in full, Borrower will also pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of Agent or its agents or employees in connection with the continuing administration of the Loans
and the related due diligence of Agent, including travel and miscellaneous expenses and fees and expenses of Agent’s outside counsel, reserve engineers and consultants engaged in connection with the Loan Documents. 
  
 (b) Indemnity. Borrower agrees to indemnify each
Lender Party, upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Lender
Party by the Borrower or any Restricted Person or by any third party growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement or defense
thereof) at any time associated therewith or contemplated therein (including any Environmental Claims or violation or noncompliance with any Environmental Laws by any Restricted Person or any liabilities or duties of any Restricted Person or any
Lender Party with respect to the presence or Release of Hazardous Materials found in or released into the environment). 
  
 THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR
THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, 
  

 65 

 provided only that no Lender Party shall be entitled under this section to receive indemnification for that portion,
if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment. If any Person (including Borrower or any of its Affiliates) ever alleges such gross
negligence or willful misconduct by any Lender Party, the indemnification provided for in this section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a court of competent jurisdiction enters a
final judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this section the term “Lender Parties” shall refer not only to the Persons designated as such in Section 1.1 but also to each
director, officer, agent, attorney, employee, representative and Affiliate of such Persons. 
  
 Section 10.5. Joint and Several Liability; Parties in Interest. All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and liabilities. All grants,
covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Restricted Person may assign or transfer any of its rights or
delegate any of its duties or obligations under any Loan Document without the prior consent of Required Lenders. Neither Borrower nor any Affiliates of Borrower shall directly or indirectly purchase or otherwise retire any Obligations owed to any
Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time
purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender Party under the Loan Documents unless and until Borrower or its Affiliates have purchased all of the
Obligations. 
  
 Section 10.6. Assignments. 
  
 (a) Any Lender may sell a participation interest in its
commitment hereunder or any of its rights under its Loans or under the Loan Documents to any Person, provided that the agreement between such Lender and such participant must at all times provide: (i) that such participation exists only as a result
of the agreement between such participant and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant
is not entitled to payment from any Restricted Person under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii)
unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any
Loan Document, except for actions which would require the consent of all Lenders under the next-to-last sentence of subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be
relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Agent and Borrower.

  

 66 

 (b) Except for sales of participations under the immediately preceding subsection (a), no
Lender shall make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance
with the following requirements: 
  
 (i) Each
such assignment shall apply to all Obligations owing to the assignor Lender hereunder and to the unused portion of the assignor Lender’s commitments, so that after such assignment is made the assignor Lender shall have a fixed (and not a
varying) Percentage Share in its Loans, Letter of Credit Outstandings and Note and be committed to make that Percentage Share of all future Loans and participations in Letters of Credit, the assignee shall have a fixed Percentage Share in such
Loans, Letter of Credit Outstandings and Note and be committed to make that Percentage Share of all future Loans and participations in Letters of Credit, the Percentage Share of the aggregate of the Commitment of the assignor shall not be less than
$10,000,000 (unless such assignor is assigning all of its Percentage Share of the Commitment) and the Percentage Share of the aggregate of the Commitment of the assignee shall equal or exceed $5,000,000. 
  
 (ii) The parties to each such assignment shall execute and
deliver to Agent, for its acceptance and recording in the “Register” (as defined below in this section), an Assignment and Acceptance in the form of Exhibit E, appropriately completed, together with the Note subject to such assignment and
a processing fee payable to Agent of $4,000. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (i) Borrower shall issue new Notes to such assignor and assignee upon
return of the old Notes to Borrower, and (ii) as of the “Settlement Date” specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereupon deliver to Borrower and
each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the Percentage Shares of all other Lenders. 
  

(iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue
Code of 1986, as amended) for Federal income tax purposes, shall (to the extent it has not already done so) provide Agent and Borrower with the “Prescribed Forms” referred to in Section 3.6(d). 
  
 (c) Nothing contained in this section shall prevent or
prohibit any Lender from assigning or pledging all or any portion of its Loans and Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank or to one of its Affiliates; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder.

 (d) By executing and delivering an Assignment and Acceptance, each assignee Lender
thereunder will be confirming to and agreeing with Borrower, Agents and each other Lender hereunder that such assignee understands and agrees to the terms hereof, including Article IX hereof. 
  
 (e) Agent shall maintain a copy of each Assignment and
Acceptance and a register for the recordation of the names and addresses of Lenders and the Percentage Shares of, and principal amount of the Loans owing to, each Lender from time to time (in this section called the “Register”). The
entries in the Register shall be conclusive, in the absence of manifest error, and Borrower and each Lender Party may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes. The Register shall be available
for inspection by Borrower or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. 
  
 Section 10.7. Confidentiality. Each Lender Party agrees that it will take all reasonable steps to keep confidential any proprietary information
given to it by any Restricted Person, provided, however, that this restriction shall not apply to information which (i) has at the time in question entered the public domain, (ii) is required to be disclosed by Law (whether valid or invalid) of any
Tribunal, (iii) is disclosed to any Lender Party’s Affiliates, auditors, attorneys, or agents, (iv) is furnished to any other Lender Party or to any purchaser or prospective purchaser of participations or other interests in any Loan or Loan
Document (provided each such purchaser or prospective purchaser first agrees to hold such information in confidence on the terms provided in this section), or (v) is disclosed in the course of enforcing its rights and remedies during the existence
of an Event of Default. 
  
 Section 10.8. Governing Law;
Submission to Process. Except to the extent that the law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the laws of the State of Texas and shall be
construed and enforced in accordance with and governed by the laws of the State of Texas and the laws of the United States of America, without regard to principles of conflicts of law. Chapter 346 of the Texas Finance Code (which regulates certain
revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or to the Notes. Borrower hereby irrevocably submits itself and each other Restricted Person to the non-exclusive jurisdiction of the state and federal
courts sitting in the State of Texas and agrees and consents that service of process may be made upon it or any Restricted Person in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under Texas or federal
law. 
  
 Section 10.9. Limitation on Interest. Lender
Parties, Restricted Persons and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and
provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable Law from time
to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required
to pay interest thereon in excess of the 

  

 68 

 
maximum amount that may be lawfully charged under applicable Law from time to time in effect, and the provisions of this section shall control over all other
provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender Parties expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation
is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any
other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be
charged by applicable Law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such
Lender’s or holder’s option, promptly returned to US Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount
permitted under applicable Law, Lender Parties and Restricted Persons (and any other payors thereof) shall to the greatest extent permitted under applicable Law, characterize any non-principal payment as an expense, fee or premium rather than as
interest, exclude voluntary prepayments and the effects thereof, and amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the
amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable Law in order to lawfully charge the maximum amount of interest permitted under applicable Law. In the event
applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code;
provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As used in this section the term “applicable Law” means the Laws of the State of Texas or the Laws of the United States of
America, whichever Laws allow the greater interest, as such Laws now exist or may be changed or amended or come into effect in the future. 
  
 Section 10.10. Termination: Limited Survival. In its sole and absolute discretion Borrower may at any time that no Obligations are owing elect in a
written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from
all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6,
and any obligations which any Person may have to indemnify or compensate any Lender Party shall survive any termination of this Agreement or any other Loan Document. At the request and expense of Borrower, Agent shall prepare and execute all
necessary instruments to reflect and effect such termination of the Loan Documents. Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender. 
  
 Section 10.11. Severability. If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law. 
  

 69 

 Section 10.12. Counterparts. This Agreement may be separately executed in any number of
counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. 
  

Section 10.13. Waiver of Jury Trial, Punitive Damages, etc. Borrower and each Lender Party hereby knowingly, voluntarily, intentionally, and
irrevocably (a) waives, to the maximum extent not prohibited by Law, any right it may have to a trial by jury in respect of any litigation based hereon, or directly or indirectly at any time arising out of, under or in connection with the Loan
Documents or any transaction contemplated thereby or associated therewith, before or after maturity; (b) waives, to the maximum extent not prohibited by Law, any right it may have to claim or recover in any such litigation any “Special
Damages”, as defined below, (c) certifies that no party hereto nor any representative or agent or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to
enforce the foregoing waivers, and (d) acknowledges that it has been induced to enter into this Agreement, the other Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications
contained in this section. As used in this section, “Special Damages” includes all special, consequential, exemplary, or punitive damages (regardless of how named), but does not include any payments or funds which any party hereto has
expressly promised to pay or deliver to any other party hereto. 
  
 Section 10.14. Release of Collateral. Agent and each Lender Party hereby agree that so long as no Event of Default shall have occurred and be continuing, Agent shall release from the Security Documents, upon written request by
Borrower and at Borrower’s expense, interests in oil and gas properties sold or otherwise transferred by any Restricted Person in compliance with Section 7.5(c), upon receipt of the indefeasible prepayment of the Loans and Letter of Credit
Outstandings required in connection with such sale, if any. In connection with the prior sale of W&T Offshore, L.L.C., a Louisiana limited liability company (“W&T LLC”), to Mr. Krohn and Mrs. Freel for approximately $1,000,000, the
Agent is authorized by the Lenders and the Issuer to release the guaranty of W&T LLC and the Security Documents executed and delivered by W&T LLC, and the liens granted thereby, without further action or consent from the Lenders or the
Issuers. No further authorization from any Lender Party shall be required in connection with any such releases. The Agent is further authorized to release the properties specified in Schedule 5 without further consent of any Lender Party. The
Borrower hereby represents that such release of such properties will not cause a breach of the requirements of Section 6.15 of the Credit Agreement. 
  
 Section 10.15. Amendment and Restatement. This Agreement restates and amends the Existing Credit Agreement in its entirety, and all of the terms
and provisions hereof shall supersede the terms and conditions thereof. Borrower hereby agrees that (i) the Loans outstanding under the Existing Credit Agreement and all accrued and unpaid interest thereon, and (ii) all accrued and unpaid fees under
the Existing Credit Agreement shall be deemed to be outstanding under and payable by this Agreement; provided that changes in the Percentage Shares, interest rates, or fee rates shall not change the amounts accrued and owing to each Lender under the
Existing Credit Agreement. 
  

 70 

 Section 10.16. Other Agents. None of the Persons identified in this Agreement as the
“Arranger” or the “Co-Syndication Agents” or the “Co-Documentation Agents” or the “Co-Agent” shall have any right, power, obligation, liability, responsibility or duty under this Agreement or any other Loan
Document other than (a) except in the case of the Arranger, those applicable to all Lenders as such or (b) as expressly provided for herein or therein. Without limiting the foregoing, none of the Other Agents shall have or be deemed to have any
fiduciary relationship with any Restricted Person or any Lender. Each of the Lenders and Borrower, on behalf of itself and the other Restricted Persons, acknowledges that it has not relied, and will not rely, on any of the Other Agents in deciding
to enter into this Agreement or in taking or not taking any action hereunder or under the Loan Documents. 
  
 Section 10.17. Exiting Lender; Assignment and Reallocation of Existing Loans, Etc. Each of Washington Mutual Bank, FA, as a lender under the
Existing Credit Agreement (the “Exiting Lender”) and the other Existing Lenders, hereby sells, assigns, transfers and conveys to the Lenders hereto, and each of the Lenders (including Societe Generale and Amegy Bank National
Association, as new Lenders hereunder) hereto hereby purchases and accepts, so much of the aggregate Commitments under, and Loans outstanding under, the Existing Credit Agreement such that, after giving effect to this Agreement (including any
increase of the commitments effectuated hereby), (a) the Exiting Lender shall cease to become a “Lender” under the Existing Credit Agreement and the “Loan Documents” as defined therein, and shall relinquish its rights (provided
that it shall still be entitled to any rights of indemnification in respect of any circumstance or event or condition arising prior to the date hereof) and be released from its obligations under the Existing Credit Agreement and the other “Loan
Documents” as defined therein, and (b) the Percentage of each Lender to this Agreement, the Loans of each Lender, and the portion of the Commitment of each Lender, shall be as set forth on Schedule 3 hereto. The foregoing assignments, transfers
and conveyances are without recourse to the Exiting Lender and without any warranties whatsoever by the Agent, the Issuers or the Exiting Lender as to title, enforceability, collectibility, documentation or freedom from liens or encumbrances, in
whole or in part, other than that the warranty of the Exiting Lender that it has not previously sold, transferred, conveyed or encumbered such interests. The Exiting Lender and the Lenders shall make all appropriate adjustments in payments under the
Existing Credit Agreement, the “Notes” and the other “Loan Documents” thereunder for periods prior to the adjustment date among themselves.
